2. REGISTRATION OF REGISTRABLE SECURITIES.

2.1 Registration on Request.

(a) Request. Subject to the limitations provided herein, following September 1, 1998, or on the first anniversary of the effective date of the Company's first registration statement under the Securities Act, whichever shall first occur, until the fifth anniversary of the effective date of the Company's first registration statement under the Securities Act, upon the written request (specifying that it is being made pursuant to this Section 2.1) of the Initiating Holders, requesting that the Company effect the registration under the Securities Act of at least fifty percent (50%) of the then-outstanding Registrable Securities, but no less than the number of Registrable Securities issued or issuable upon conversion of twenty five percent (25%) of the total number of shares of Preferred Stock issued by the Company to the Purchasers, and specifying (x) the intended method of disposition thereof, (y) whether or not such requested registration is to be an underwritten offering, and (z) the price range (net of underwriting discounts and commissions) acceptable to such Holder or Holders to be received for such Registrable Securities, the Company will within 10 business days after the Company receives such written request give written notice of such requested registration to all other Holders of Registrable Securities and thereupon the Company will use reasonable efforts to effect the registration under the Securities Act of:

(i) the Registrable Securities which the Company has been so requested to register by such Initiating Holders, and

(ii) all other Registrable Securities which the Company has been requested to register by the other Holders thereof by written request given to the Company within 15 days after the giving of such written notice by the Company (which request shall specify the same information called for by the original request to effect registration described above), all to the extent requisite to permit the disposition (in accordance with Section 2.1(b) hereof) of the Registrable Securities so to be registered.

(b) Method of Distribution. The Holders of 51% of the Registrable Securities to be included in such registration statement shall determine the method of distribution of the Registrable Securities so included; provided, however, that if no agreement of Holders of 51% or more of the Registrable Securities to be included in such registration statement is obtained, then if Holders of more than 30% of the Registrable Securities to be included in such registration statement request an underwritten public offering, an underwritten public offering shall be the method of distribution with other methods permitted to the extent the managing underwriter for such offering, in its sole discretion, agrees to other methods of distribution being covered by such registration statement.

(c) Registration of Other Securities. Whenever the Company shall effect a registration pursuant to this Section 2.1 in connection with an underwritten offering, no securities other than Registrable Securities shall be included among the securities covered by such registration unless (i) the managing underwriter of such offering shall have advised each Holder of Registrable

3

Securities to be covered by such registration in writing that the inclusion of such other securities would not adversely affect such offering or (ii) the Holders of more than 51% or more of all Registrable Securities to be covered by such registration shall have consented in writing to the inclusion of such other securities; provided, however, that the rights of Holders hereunder shall be subject to (A) the prior right of Series A Persons requesting registration (whether pursuant to "demand" or "piggyback" registration rights) to include all of the securities requested to be registered by such Series A Persons in such registration, and (B) the concurrent right of Series B Persons, Series C Persons, Series D Persons, Series F Persons, and Series G Persons requesting registration pursuant to the Series B Registration Rights Agreement, the Series C Registration Rights Agreement, the Series D Registration Rights Agreement, the Series F Registration Rights Agreement, the Grelan Series F Registration Rights Agreement, and/or the Series G Registration Rights Agreements (whether pursuant to "demand" or "piggyback" registration rights) to include securities in such registration on a pro rata basis with the Registrable Securities of Holders to be included in such registration, so that the relative proportion of the amount of securities held by Series B Persons, Series C Persons, Series D Persons, Series F Persons, Series G Persons and Holders that are actually included in such registration is the same as the relative proportion of the total amount of securities held by Series B Persons, Series C Persons, Series D Persons, Series F Persons, Series G Persons and Holders that are requested to be included in such registration pursuant to the Series B Registration Rights Agreement, the Series C Registration Rights Agreement, the Series D Registration Rights Agreement, the Series F Registration Rights Agreement, the Grelan Series F Registration Rights Agreement, the Series G Registration Rights Agreements or Registration Rights Agreements with the Holders, as the case may be.

(d) Registration Statement Form. Registrations under this
Section 2.1 shall be on such appropriate registration form of the Commission (i) as shall be selected by the Company, and (ii) as shall permit the disposition of such Registrable Securities in accordance with the method or methods of disposition selected pursuant to Section 2.1(b) hereof.

(e) Expenses. Except as otherwise provided in this Section 2.1(e) or in Section 2.1(i), the Company shall bear all expenses incurred in connection with two effective registrations pursuant to Section 2.1 hereof and each registration pursuant to Section 2.2 hereof (excluding in each case underwriting discounts and commissions applicable to Registrable Securities), including, without limitation, in each case: (i) all registration, filing and National Association of Securities Dealers fees; (ii) all fees and expenses of complying with securities or blue sky laws; (iii) all word processing, duplicating and printing expenses, messenger, delivery and shipping expenses;
(iv) the fees and disbursements of the accountants and counsel for the Company including the expenses of any special audits or "cold comfort" letters or opinions required by or incident to such registrations; (v) the fees and disbursements of the accountants and counsel for the Company for services rendered in connection with inclusion of Registrable Securities in the registration; provided, however, that if the accountants or the counsel for the Company refuse or decline to undertake such representation because of an actual or perceived conflict of interest or otherwise, then the Company shall bear the reasonable fees and disbursements of one firm of counsel and one firm of accountants (as appropriate) retained by the Holders of such Registrable Securities; (vi) premiums and other costs of policies of insurance maintained for the benefit of the Company against liabilities arising out of the public offering of the Registrable Securities; (vii) any fees and disbursements of underwriters customarily paid by issuers or sellers of securities, but excluding underwriting discounts and commissions, if any. In all cases, each Holder of Registrable Securities shall pay the underwriting discounts and commissions applicable to the securities sold by such Holder.

4

(f) Effective Registration Statement. The Company's obligation to effect a registration requested pursuant to this Section 2.1 shall not be deemed to have been fulfilled (i) unless a registration statement with respect thereto has become effective (unless a substantial cause of the failure of such registration statement to become effective shall be attributable to one or more Holders of Registrable Securities whose securities were to have been included in such registration statement), (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason, resulting in a failure to consummate the offering of Registrable Securities offered thereby, (iii) if after a registration statement with respect thereto has become effective, the offering of Registrable Securities offered thereby is not consummated due to factors beyond the control of the Holders of such Registrable Securities, including without limitation in the context of a proposed firm commitment underwriting, the fact that the underwriters have advised the Holders of such Registrable Securities that such Registrable Securities cannot be sold at a net price equal to or above the net price specified in the notice to the Company at the time of the request, or (iv) if the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such registration are not satisfied (unless a substantial cause of such conditions to closing not being satisfied shall be attributable to one or more Holders of Registrable Securities whose Registrable Securities were included in such registration statement).

(g) Selection of Underwriters. If a requested registration pursuant to this Section 2.1 involves an underwritten offering, the underwriter or underwriters thereof shall be selected by the Company with the approval of the Holders of at least 50% of the Registrable Securities to be so registered, which approval will not be unreasonably withheld.

(h) Priority in Requested Registrations. If a requested registration pursuant to this Section 2.1 involves an underwritten offering, and the managing underwriter shall advise the Company in writing (with a copy to each Holder requesting registration) that, in its opinion, the number of securities requested to be included in such registration exceeds the number which can be sold in such offering within a price range acceptable to the Holders of more than 50% of the Registrable Securities requested to be included in such registration, then the Registrable Securities requested to be registered pursuant to this Section 2.1 shall be reduced to the number of Registrable Securities which the Company is so advised can be sold in (or during the time of) such offering by decreasing the Registrable Securities requested to be registered (pro rata among the Holders requesting such registration on the basis of the percentage of the Registrable Securities held by such Holder immediately prior to the filing of the registration statement with respect to such registration). Nothing in this Section 2.1(h) shall affect (i) the rights of Series A Persons requesting registration to include all of the securities requested to be registered by such Series A Persons in such registration without reduction prior to the inclusion of any Registrable Securities requested to be registered hereunder, or (ii) the rights of Series B Persons, Series C Persons, Series D Persons, Series F Persons, and Series G Persons requesting registration to include securities in such registration on a pro rata basis with the Registrable Securities of Holders hereunder in the same manner as described in
Section 2.1(c) hereof.

(i) Form S-3. Notwithstanding the other provisions of this
Section 2.1, until the fifth anniversary of the effective date of the Company's first registration statement under the Securities Act, the Company shall be required upon the written request of Holder(s) by this Section 2.1 to effect, and bear all expenses (as determined pursuant to Section 2.1(e) hereof) incurred in connection with, up to

5

two registrations on Form S-3 (or any successor similar form) of Registrable Securities during such period, provided that the Registrable Securities to be registered thereon are expected to have an aggregate disposition price (before deductions for underwriting discounts and commissions) of at least $500,000.

(j) Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to prepare and file any other registration statement pursuant to this Section 2.1 within 180 days of the consummation of an underwritten public offering of Common Stock pursuant to a registration statement filed under the Securities Act.

2.2 Incidental Registration.

(a) Right to Include Registrable Securities. If the Company at any time prior to the fifth anniversary of the effective date of the Company's first registration statement under the Securities Act proposes to register any of its securities under the Securities Act (other than by a registration on Form S-8, S-4 or any successor similar forms or any other form not available for registering the Registrable Securities for sale to the public and other than pursuant to Section 2.1 hereof), whether or not for sale for its own account, it will each such time, at least 15 days prior to filing the registration statement, give written notice to all Holders of Registrable Securities of its intention to do so. Upon the written request of Holders of an aggregate of at least 25,000 shares (appropriately adjusted for subdivisions and combinations of shares of Common Stock and dividends on Common Stock payable in shares of Common Stock hereafter) of Registrable Securities, made within 15 days after the receipt of any such notice (which request shall specify the Registrable Securities intended to be disposed of by each such Holder and the intended method of disposition thereof), the Company will use reasonable efforts to effect the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Holders of such Registrable Securities, to the extent requisite to permit the disposition (determined pursuant to the provisions of Section 2.1(b) hereof) of the Registrable Securities so to be registered, provided that if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to each Holder of Registrable Securities and, thereupon, (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay expenses in accordance with Section 2.1(e) hereof), without prejudice, however, to the rights of any Holder or Holders of Registrable Securities entitled to do so to request that such registration be effected as a registration under Section 2.1 hereof, and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities being registered pursuant to this Section 2.2(a), for the same period as the delay in registering such other securities. No registration effected under this Section 2.2 shall relieve the Company of its obligation to effect any registration upon request under Section 2.1 hereof.

(b) Priority in Incidental Registrations. If (i) a registration pursuant to this Section 2.2 involves an underwritten offering of the securities so being registered, whether or not for sale for the account of the Company, to be distributed (on a firm commitment basis) by or through one or more underwriters of recognized standing, whether or not the Registrable Securities so requested to be

6

registered for sale for the account of Holders of Registrable Securities are also to be included in such underwritten offering, and (ii) the managing underwriter of such underwritten offering shall inform the Company and the Holders of the Registrable Securities requesting such registration by letter of its belief that the number of securities requested to be included in such registration exceeds the number which can be sold in (or during the time of) such offering, then the Company may include in such offering all securities proposed by the Company to be sold for its own account and may decrease the number of Registrable Securities and other securities of the Company that persons have requested to be included in such registration by (a) first decreasing the securities requested to be included in such registration other than Registrable Securities (pro rata among the persons requesting such registration on the basis of the number of shares of such securities held by such person immediately prior to the filing of the registration statement with respect to such registration) and (b) then, to the extent necessary, decreasing the Registrable Securities requested to be registered (pro rata among the Holders requesting such registration on the basis of the percentage of the Registrable Securities held by such Holders immediately prior to the filing of the registration statement with respect to such registration); provided, however, that the rights of Holders hereunder shall be subject to (i) the right of the Series A Persons requesting inclusion of securities in such registration to include all of the securities requested to be registered by such Series A Persons in such registration without reduction prior to the inclusion of any Registrable Securities requested to be included in such registration pursuant to this Section 2.2., and (ii) the rights of Series B Persons, Series C Persons, Series D Persons, Series F Persons, and Series G Persons requesting registration to include securities in such registration on a pro rata basis with the Registrable Securities of Holders hereunder in the same manner as described in
Section 2.1(c) hereof.

2.3 Registration Procedures. If and whenever the Company is required to use reasonable efforts to effect the registration of any Registrable Securities under the Securities Act as provided in Sections 2.1 and 2.2 hereof, the Company will, subject to the limitations provided herein, as expeditiously as possible:

(a) prepare and (as soon thereafter as possible or in any event no later than 60 days after the end of the period within which requests for registration may be given to the Company or such longer period as the Company shall in good faith require to produce the financial statements required in connection with such registration) file with the Commission the requisite registration statement to effect such registration and thereafter use reasonable efforts to cause such registration statement to become effective, provided that the Company may discontinue any registration of its securities which are not Registrable Securities (and, under the circumstances specified in
Section 2.2(a) hereof, its securities which are Registrable Securities) at any time prior to the effective date of the registration statement relating thereto;

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement until such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement; provided, however, that the Company shall not in any event be required to keep the registration statement effective for a period of more than three months after such registration statement becomes effective;

7

(c) furnish to each seller of Registrable Securities covered by such registration statement such number of conformed copies of such registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424 under the Securities Act, and such other documents, as such seller may reasonably request;

(d) use reasonable efforts to register or qualify all Registrable Securities and other securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as each seller thereof shall reasonably request, to keep such registration or qualification in effect for so long as such registration statement remains in effect (provided, however, that the Company shall not in any event be required to keep such registration or qualification in effect for a period of more than three months after such registration or qualification becomes effective), and take any other action which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the securities owned by such seller, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this subdivision (d) be obligated to be so qualified or to consent to general service of process in any such jurisdiction;

(e) use reasonable efforts to cause all Registrable Securities covered by such registration statement to be registered with or approved by such other United States federal or state governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Registrable Securities;

(f) furnish to each seller of Registrable Securities a copy, or, upon request, a signed counterpart, addressed to such seller (and the underwriters, if any) of

(i) an opinion of counsel for the Company, dated the effective date of such registration statement (or, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting agreement), and

(ii) a "comfort" letter addressed to the underwriters, dated the effective date of such registration statement (or, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting agreement), signed by the independent public accountants who have audited the Company's financial statements included in such registration statement, covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and, in the case of the accountants' letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer's counsel and in accountants' letters delivered to the underwriters in underwritten public offerings of securities and, in the case of the accountants' letter, such other financial matters, and, in the case of the legal opinion such other legal matters, as such seller or such Holder (or the underwriters, if any) may reasonably request;

8

(g) notify each seller of Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that, or upon the happening of any event as a result of which, the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and at the request of any such seller, prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made;

(h) otherwise use reasonable efforts to comply with all applicable rules and regulations of the Commission, and, if required under applicable regulations, make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act, and will furnish to each such seller, upon request of such seller, prior to the filing thereof a copy of any amendment or supplement to such registration statement or prospectus and shall not file any such supplement or amendment if such seller shall have delivered to the Company an opinion of counsel that such amendment or supplement does not comply in all material respects with the requirements of the Securities Act or of the rules or regulations thereunder;

(i) provide and cause to be maintained a transfer agent for all Registrable Securities covered by such registration statement from and after a date not later than the effective date of such registration statement;

(j) use reasonable efforts to list all Registrable Securities covered by such registration statement on any securities exchange on which the Common Stock is then listed; and

(k) refrain from making any sale or distribution of its equity securities, except pursuant to any employee stock option plan or other employee benefit plan and any preexisting agreement for the sale of such securities, for at least 90 days after the closing of the public offering pursuant to such registration.

It shall be a condition precedent to the obligations of the Company to take any action with respect to registering a Holder's Registrable Securities pursuant to this Section 2.3 that such seller of Registrable Securities as to which any registration is being effected furnish the Company in writing such information regarding such seller, the Registrable Securities and other securities of the Company held by such seller, and the distribution of such securities as the Company may from time to time reasonably request in writing. If a Holder refuses to provide the Company with any of such information on the grounds that it is not necessary to include such information in the registration statement, the Company may exclude such Holder's Registrable Securities from the registration statement if the Company provides such Holder with an opinion of counsel to the effect that such information must be included in the registration statement and such Holder thereafter continues to

9

withhold such information. The deletion of such Holder's Registrable Securities from a registration statement shall not affect the registration of the other Registrable Securities to be included in such registration statement.

Each Holder of Registrable Securities agrees by acquisition of such Registrable Securities that upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.3(g), such Holder will forthwith discontinue such Holder's disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.3(g) and, if so directed by the Company, will deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice.

2.4 Underwritten Offerings.

(a) Requested Underwritten Offerings. If requested by the underwriters for any underwritten offering of Registrable Securities pursuant to a registration requested under Section 2.1 hereof, the Company will enter into an underwriting agreement with such underwriters for such offering, the portions of such agreement that relate to Holders of Registrable Securities being registered to be reasonably satisfactory in substance and form to each Holder of Registrable Securities being registered and to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of this type, including, without limitation, indemnities substantially to the effect and to the extent provided in Section 2.6 hereof. Each such Holder of Registrable Securities will cooperate with the Company in the negotiation of the underwriting agreement and will give consideration to the reasonable requests of the Company regarding the form thereof, provided that nothing herein contained shall diminish the foregoing obligations of the Company. If requested by the underwriters of any underwritten offering pursuant to a registration under Section 2.1 hereof, each Holder of Registrable Securities agrees by acquisition of such Registrable Securities to enter into an agreement with such underwriters not to sell his or its shares of stock in the Company for a period of time (not to exceed 180 days) after the effectiveness of a registration statement equal to the period of time which the sellers of securities in such registration, by separate agreement with the underwriters, have agreed not to sell their shares after the effectiveness of such registration statement. The Holders of Registrable Securities to be distributed by such underwriters shall be parties to such underwriting agreement. Any such Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder's Registrable Securities and other securities of the Company, such Holder's intended method of distribution, and any representations, warranties or agreements required by law.

(b) Incidental Underwritten Offerings. If the Company at any time proposes to register any of its securities under the Securities Act as contemplated by Section 2.2 hereof and such securities are to be distributed by or through one or more underwriters, the Company will, if requested by any Holder of Registrable Securities as provided in Section 2.2 hereof and subject to the provisions of Section 2.2(b) hereof, arrange for such underwriters to include all the Registrable Securities to be offered and sold by such Holder owning the securities to be distributed by such underwriters. In such event, the Holders of Registrable Securities to be distributed by such underwriters shall be parties to the underwriting agreement between the Company and such underwriters. Any such Holder shall not

10

be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder's Registrable Securities or other securities of the Company, such Holder's intended method of distribution and any representations, warranties or agreements required by law.

2.5 Preparation; Reasonable Investigation. In connection with the preparation and filing of each registration statement under the Securities Act pursuant to this Agreement, the Company will give the Holders of Registrable Securities registered under such registration statement, their underwriters, if any, and one counsel or firm of counsel and one accountant or firm of accountants representing all the Holders of Registrable Securities to be registered under such registration statement, the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the Commission, and each amendment thereof or supplement thereto, and will give each of them such access to its books and records and such opportunities to discuss the business of the Company with its officers and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of such Holders' and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act.

2.6 Indemnification.

(a) Indemnification by the Company. In the event any Registrable Securities are included in a registration statement under this
Section 2, to the extent permitted by law, the Company will, and hereby does, indemnify and hold harmless the seller of any Registrable Securities covered by such registration statement, its directors and officers, each other person who participates as an underwriter in the offering or sale of such securities and each other person, if any, who controls such seller or any such underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller or any such director or officer or underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse such seller and each such director, officer, underwriter and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such seller expressly for use in the preparation thereof, and provided further that the Company shall not be liable to any person who participates as an underwriter in the offering or sale of Registrable Securities or any other Person, if any, who controls such underwriter within the meaning of the Securities Act, in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of such person's failure to send or give a

11

copy of the final prospectus, as the same may be then supplemented or amended, to the person asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of the Registrable Securities to such person if such statement or omission was corrected in such final prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer, underwriter or controlling person and shall survive the transfer of such securities by such seller.

(b) Indemnification by the Sellers. The Company may require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2.3 hereof, that the Company shall have received an undertaking satisfactory to it from the prospective seller of such securities, to indemnify and hold harmless (in the same manner and to the same extent as set forth in subdivision (a) of this Section 2.6) each underwriter, each person who controls such underwriter within the meaning of the Securities Act, the Company, each director of the Company, each officer of the Company and each other person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in strict conformity with written information furnished to the Company by such seller expressly for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement; provided that such prospective seller shall not be liable to any person who participates as an underwriter in the offering or sale of Registrable Securities or any other person, if any, who controls such underwriter within the meaning of the Securities Act, in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of such person's failure to send or give a copy of the final prospectus, as the same may be then supplemented or amended, to the person asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such person if such statement or omission was corrected in such final prospectus. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of any underwriter, the Company or any such director, officer or controlling person and shall survive the transfer of such securities by such seller. In no event shall the liability of any selling holder of Registrable Securities under this Section 2.6(b) be greater in amount than the dollar amount of the proceeds received by such holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding subdivisions of this Section 2.6, as a condition to the obligations of the indemnifying party with respect thereto, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding subdivisions of this Section 2.6, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the

12

defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) Other Indemnification. Indemnification similar to that specified in the preceding subdivisions of this Section 2.6 (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation of any governmental authority other than the Securities Act.

(e) Indemnification Payments. The indemnification required by this Section 2.6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.

(f) Contribution. If the indemnification provided for in this
Section 2.6 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue statement of material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 2.6(c) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

The Company and, as a condition to the registration of any of their Registrable Securities, the Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.6(f) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.6(f), no underwriter shall be required to contribute any amount in excess of the amount by which the aggregate total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no selling Holder shall be required to contribute any amount in excess of the amount by which the aggregate total price at which the Registrable Securities of such selling Holder were offered to the public exceeds the amount of any damages which such selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission. No person guilty of fraudulent misrepresentation (within the

13

meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

2.7 Reporting Requirements Under Exchange Act. When it is first legally required to do so, the Company shall register its Common Stock under Section 12 of the Exchange Act (as hereinabove defined) and shall keep effective such registration and shall timely file such information, documents and reports as the Commission may require or prescribe under Section 13 of the Exchange Act. From and after the effective date of the first registration statement filed by the Company under the Securities Act, the Company shall (whether or not it shall then be required to do so) timely file such information, documents and reports which a corporation, partnership or other entity subject to Section 13 or 15(d) (whichever is applicable) of the Exchange Act is required to file.

Immediately upon becoming subject to the reporting requirements of either Section 13 or 15(d) of the Exchange Act, the Company shall forthwith upon request furnish any Holder of Registrable Securities (i) a written statement by the Company that it has complied with such reporting requirements, (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents filed by the Company with the Commission as such Holder may reasonably request in availing itself of an exemption for the sale of Registrable Securities without registration under the Securities Act. The Company acknowledges and agrees that the purposes of the requirements contained in this Section 2.7 are (a) to enable any such Holder to comply with the current public information requirement contained in Paragraph
(c) of Rule 144 should such Holder ever wish to dispose of any of the securities of the Company acquired by it without registration under the Securities Act in reliance upon Rule 144 (or any other similar exemptive provision) and (b) to qualify the Company for the use of registration statements on Form S-3. In addition, the Company shall take such other measures and file such other information, documents and reports, as shall hereafter be required by the Commission as a condition to the availability of Rule 144 under the Securities Act (or any similar exemptive provision hereafter in effect) and the use of Form S-3. The Company also covenants to use reasonable efforts, to the extent that it is reasonably within its power to do so, to qualify for the use of Form S-3.

2.8 Shareholder Information. The Company may require each Holder of Registrable Securities as to which any registration is to be effected pursuant to this Section 2 to furnish the Company such information in writing with respect to such Holder and the distribution of such Registrable Securities as the Company may from time to time reasonably request in writing and as shall be required by law or by the Commission in connection therewith.

2.9 Forms. All references in this Agreement to particular forms of registration statements are intended to include, and shall be deemed to include, references to all successor forms which are intended to replace, or to apply to similar transactions as, the forms herein referenced.

2.10 Transfer of Registration Rights. The registration rights granted to the Holders of Registrable Securities under this Section 2 may not be transferred without the prior written consent of the Company; provided that such registration rights may be transferred, in whole or in part, without such prior written consent in connection with the transfer of Registrable Securities to (i) an affiliate (defined as any person which directly or indirectly controls, is controlled by, or is under common control with such Holder) of one or more of the Holders or (ii) to an immediate or remote transferee of a Holder who after such transfer is the Holder of at least 50% of the number of Registrable

14

Securities purchased by such original Holder hereunder as set forth on Schedule A hereto (appropriately adjusted for subdivisions and combinations of shares of Common Stock and dividends on Common Stock payable in shares of Common Stock subsequent to the date of this Agreement).

Each such notice or other communication shall for all purposes of this Agreement be treated as effective upon receipt, if delivered personally or by courier, or, if sent by mail, at the earlier of its receipt or 48 hours after same has been deposited in a regularly maintained receptacle for deposit of the United States mail, addressed and mailed as aforesaid.

3.5 Delays or Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to any party to this Agreement shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

PRELIMINARY STATEMENTS

Shareholder has entered into that one certain Settlement Agreement dated April 1, 2003 (the "Settlement Agreement"), by and between Shareholder and the Company pursuant to which the Shareholder has agreed to transfer the Shares to a Voting Trust to be held and administered under the terms thereof. A copy of the Settlement Agreement is attached hereto as Exhibit A and incorporated herein for all purposes.

Donald M. Delwood has agreed to serve as Trustee of the Voting Trust.

STATEMENT OF AGREEMENT

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other good, valuable and binding consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

Section 1. Assignment, Delivery and Transfer of Shares; Issuance of Voting Trust Certificates. Simultaneously with the execution of this Agreement, Shareholder will assign and deliver to Trustee a certificate representing 75,000 shares of Common Stock of the Company. Trustee shall cause the Shares to be transferred to the Trustee on the books of the Company and shall issue and deliver to Shareholder a certificate for the number of shares transferred to Trustee in substantially the form indicated on Exhibit B attached hereto ("Voting Trust Certificate").

Section 2. Deposit of Additional Shares. Upon receipt of any additional shares of Common Stock or other securities of the Company subsequent to the date of this Agreement, Shareholder shall deposit with Trustee the certificates representing such additional shares, and Trustee shall cause the transfer to be recognized on the books of the Company and shall issue and deliver to Shareholder a Voting Trust Certificate representing the number of shares transferred.


Section 3. Voting by Trustee. During the period of this Agreement, Trustee shall have the exclusive right to vote the Shares or give written consent, in person or by proxy, at all meetings of the shareholders of the Company, and in all proceedings in which the vote or written consent of shareholders of the Company may be required or authorized by law. On each matter presented to him for vote, the Trustee shall be required to vote the Shares in a manner so that the percentage of the Shares voted in favor of a particular matter and the percentage of the Shares voted against a particular matter by the Trustee equals the percentage of the total number of shares of stock (including Common Stock and Preferred Stock, if any) of the Company voted in favor of that particular matter and the percentage of the total number of shares of stock of the Company voted against that particular matter.

Section 4. Dividends. In the event that the Company issues dividends, Trustee shall accept and receive such dividends for the benefit of Shareholder, and shall thereafter deliver such dividends to Shareholder; provided, however, in the event that the dividends are in the form of share certificates having voting rights, Trustee shall not deliver the share certificates to Shareholder, but shall instead retain the share certificates and issue a new Voting Trust Certificate representing the share dividends.

Section 5. Termination of the Trust. The Voting Trust shall terminate on the earliest occurrence of any of the following:

(a) A vote for termination by a majority of the Board of Directors of the Company;

(b) Six (6) months and seven (7) days after the effective date of a Registration Statement of the Company filed under the Securities Act of 1933, as amended (the "Securities Act") and including securities to be sold on behalf of the Company to the public in a firm commitment underwritten offering under the Securities Act;

(c) Ten years after the effective date of this Agreement; or

(d) The death of Dr. Gopal M. Nair.

On termination of this Agreement, Shareholder shall surrender the Voting Trust Certificates to Trustee and Trustee shall obtain from the Company and deliver to Shareholder shares of Company stock properly endorsed for transfer, equivalent to the amount of shares represented by the Voting Trust Certificates surrendered.

Section 6. Sale or Transfer of Shares. Subject to the Company's right of first refusal as set forth in Section 3 of the attached Settlement Agreement and subject to any applicable lock-up agreement on the part of Shareholder as provided in Section 13.B. of the attached Settlement Agreement, if at any time during the term of this Agreement the Shareholder desires to sell or transfer all or a portion of the Shares to a third party, he

2

shall have the right to do so by notifying the Trustee in writing of his intent to sell or transfer such portion of the Shares. The Trustee shall make the appropriate notations in the records of the Trust and shall, after the transferor has delivered the Voting Trust Certificate(s) representing that portion of the Shares to be transferred to the Trustee for cancellation, issue new Voting Trust Certificate(s) to the transferee and transferor, as applicable, representing the portion of the Shares transferred to the transferee and the portion retained by the transferor, if applicable. Any transferee of such portion of the Shares shall become a party to and agree to be bound by this Agreement. Any purported transfer of all or a portion of the Shares to a person or entity that has not become a party to this Agreement shall be null and void. Any transferee of all or a portion of the Shares shall have all rights and shall be subject to all limitations of the transferor under the applicable Voting Trust Certificate and this Agreement with respect to the Shares so transferred to such transferee.

Section 7. Replacement of Trustee. The Trustee may be removed from his office by the affirmative vote of a majority of the Board of Directors of the Company. In the event of the death, resignation or removal of Trustee, the successor Trustee shall be appointed by majority vote of the Board of Directors of the Company.

Section 8. Liability and Indemnity of Trustee. The Trustee shall not be liable for any error of judgment or mistake of fact or law, or for any act or omission undertaken in good faith in connection with the Trustee's powers and duties under this Agreement, except to the extent due to the Trustee's own willful misconduct or gross negligence. The Trustee is authorized and empowered to construe this Agreement and his reasonable construction made in good faith shall be conclusive and binding. The Trustee shall not be liable for acting on any legal advice or on any notice(s), request(s) or instruction(s), or any other document(s) believed by the Trustee to be genuine and to have been signed by the proper party or parties. The Trustee shall be entitled to be indemnified fully from the distributions coming to his hand for any expenses, claims, losses, damages or liabilities, including, without limitation, attorneys' fees incurred by the Trustee and arising out of or in connection with the administration of the Trust established by this Agreement and his rights and duties hereunder, except to the extent that the action giving rise to such indemnification was the result of willful misconduct or gross negligence by the Trustee ("Losses"). Each holder of record of a Voting Trust Certificate representing all or a portion of the Shares held pursuant hereto covenants with the Trustee that in the event monies and securities in the Trustee's hands are insufficient to indemnify the Trustee against all Losses, each such holder shall, in proportion to the portion of the Shares represented by the Voting Trust Certificate held by such holder, hold harmless and keep indemnified the Trustee against all Losses.

Section 9. Trustee's Compensation. Trustee shall serve in his capacity as Trustee without compensation of any kind except that his expenses lawfully incurred in the administration of his duties as Trustee shall be reimbursed to him by the Company. Notwithstanding the foregoing, Trustee or any of his successors may not serve the

3

Company or any of its affiliates as a director, employee or officer but may serve in any other capacity, and in such capacity may receive compensation from the Company.

Section 10. Notices from the Company. All notices, reports, statements, and other communications directed to Trustee from the Company shall be promptly forwarded to Shareholder.

Section 11. Copies of the Agreement. This Agreement may be executed in multiple counterparts but shall not otherwise be separable or divisible. Upon the execution of this Agreement and the establishment of the Voting Trust, Trustee shall cause a copy of this Agreement to be filed in the registered office of the Company. This Agreement shall be open to inspection in the manner provided for inspection under Article 2.30 of the Texas Business Corporation Act.

Section 12. Governing Law. This Agreement is intended by the parties to be governed and construed in accordance with the laws of the State of Texas, without regard to the conflicts of law principles thereof.

Section 13. Severability of Provisions. This Agreement shall not be severable or divisible in any way, but it is specifically agreed that, if any provision should be invalid, the invalidity shall not affect the validity of the remainder of the Agreement.

Section 14. Arbitration: Agreement Disputes. In the event of any and all disputes arising under this Agreement, the parties hereto agree to try in good faith, to settle such dispute amicably between them. If a dispute has not been settled after thirty (30) days of good-faith negotiation, then the parties hereto agree that any dispute or controversy arising out of or relating to any interpretation, construction, performance or breach of this Agreement shall be settled by arbitration to be held in New Orleans, Louisiana, in accordance with the rules then in effect of the American Arbitration Association. The arbitration shall be held by one arbitrator selected in accordance with the rules then in effect of the American Arbitration Association. The arbitrator may grant injunctions or other relief in such dispute or controversy. The decision of the arbitrator shall be final, conclusive and binding on the parties to the arbitration. Judgment may be entered on the arbitrator's decision in any court having jurisdiction. Each party hereto shall pay one-half of the costs and expenses of the arbitrator and the American Arbitration Association for such arbitration, and each party shall separately pay its counsel fees and expenses, provided that the Company shall reimburse the Trustee for the costs of such arbitration and counsel fees and expenses in connection with such arbitration proceeding. The arbitrator will be informed that he is not to award any punitive damages or exemplary damages. Any arbitration suit will be governed by the laws of the State of Texas, without regard to the conflicts of law principles thereof. Each party hereto acknowledges that compliance with the provisions of this Agreement is necessary to protect the proprietary interests of the other party. Each party hereto agrees that in addition to the arbitration provisions contained herein, in the event of a breach of

4

this Agreement by a party hereto, the other party hereto shall be authorized and entitled to seek and obtain immediate injunctive relief from any court of competent jurisdiction.

Section 15. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. Facsimile signatures shall have the same force and effect as original signatures, provided, however, that any party who provides a facsimile signature agrees to provide an original signature within a reasonable time.

Section 16. Construction by Trustee. Trustee is authorized and empowered to construe this Agreement. His reasonable construction made in good faith shall be conclusive and binding on Shareholder.

STATEMENT OF AGREEMENT

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other good, valuable and binding consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

Section 1. Assignment, Delivery and Transfer of Shares; Issuance of Voting Trust Certificates. Simultaneously with the execution of this Agreement, Shareholders will assign and deliver to Trustee a certificate or certificates representing 34,000 shares of Common Stock of the Company. Trustee shall surrender the certificates to the Company and the Company shall cancel the certificates. New share certificates shall be issued in the name of the Trustee and the new certificates shall state that they are issued pursuant to this Agreement. That fact shall also be noted in the Company's stock transfer records in the entry of Trustee's ownership of the shares.

Upon receipt of any additional shares of Common Stock or other securities of the Company subsequent to the date of this Agreement, each Shareholder shall deposit with Trustee the certificates representing such additional shares, and Trustee shall cause the transfer to be recognized on the books of the Company and shall issue and deliver to Jeffrey A. Goldberg, Shareholders' Attorney, a Voting Trust Certificate representing the number of shares transferred.

Section 3. Voting by Trustee. During the period of this Agreement, Trustee shall have the exclusive right to vote the Shares or give written consent, in person or by proxy, at all meetings of the shareholders of the Company, and in all proceedings in which the vote or written consent of shareholders of the Company may be required or authorized by law. On each matter presented to him for vote, the Trustee shall be required to vote the Shares in a manner so that the percentage of the Shares voted in favor of a particular matter and the percentage of the Shares voted against a particular matter by the Trustee equals the percentage of the total number of shares of stock (including Common Stock and Preferred Stock, if any) of the Company voted in favor of that particular matter and the percentage of the total number of shares of stock of the Company voted against that particular matter. The Trustee shall not vote the Shares in favor of the sale, mortgage, or pledge of all or substantially all of the assets of the Company or for any merger, consolidation, reorganization, or dissolution of the Company, except with the consent of the owners of two-thirds (2/3), or more in interest of the Voting Trust Certificates at a meeting of owners of not less than two-thirds (2/3) in interest of the Voting Trust Certificates.

Section 4. Dividends. In the event that the Company issues dividends, Trustee shall accept and receive such dividends for the benefit of the Shareholders, and shall within a reasonable time thereafter deliver a percentage of such dividends received by Trustee to Jeffrey A. Goldberg, Shareholders' Attorney, which percentage for each Shareholder shall be equal to the percentage that the number of shares of BioNumerik stock transferred by such Shareholder to Trustee bears to the total number of Shares; provided, however, in the event that the dividends are in the form of share certificates having voting rights, Trustee shall not deliver the share certificates to Shareholders, but shall instead retain the share certificates and issue new Voting Trust Certificates representing the share dividends. Any shares issued as dividends shall become subject to this Agreement to the same extent as if they were originally deposited under it. In the event of dissolution or total or partial liquidation of the Company, the Trustee shall receive any moneys, securities, rights, or property to which the Shareholders may be entitled, and shall distribute it for the benefit of the Voting Trust Certificate holders consistent with their ownership percentage to Jeffrey A. Goldberg, Shareholders' Attorney.

2

(a) A vote for termination by a majority of the Board of Directors of the Company; or

(c) Ten years after the effective date of this Agreement; or

(d) The death of both Dasharatha G. Reddy and Dhanabalan Murali.

On termination of this Agreement, Shareholders shall surrender the Voting Trust Certificates to Trustee and Trustee shall obtain from the Company and deliver with respect to each Shareholder to Jeffrey A. Goldberg, Shareholders' Attorney, shares of Company stock properly endorsed for transfer, equivalent to the amount of shares represented by the Voting Trust Certificates surrendered by each Shareholder.

Section 6. Sale or Transfer of Shares.

If a license has not been executed by the end of the Negotiation Period, then BioNumerik shall be free to enter into a third party license and/or alliance with respect to the Product(s) for the territory of Canada, provided the economic terms of such license and/or alliance are no more favorable to such third party than the terms last proposed by ASTA Medica before expiration of the Negotiation Period.

7. MANUFACTURING.

7.1 Manufacturing Rights. BioNumerik will retain all manufacturing rights related to the Product(s) in all parts of the world (including the Territory), subject to ASTA Medica's non-exclusive option described in Section 7.2.

7.2 Non-Exclusive Manufacturing Option for Territory. ASTA Medica is hereby granted the option to bid to manufacture Product(s) for development and regulatory approval and/or sale in the Territory. From time to time during the term of this Agreement, ASTA Medica shall, at its option, provide BioNumerik with a bid containing the price, delivery amount and other material terms under which it would manufacture Product(s) for the Territory on a non-exclusive basis. It is the hope of the Parties that ASTA Medica will be a significant manufacturer of Product supply in the Territory, subject to meeting the competitive requirements of price, quality, supply, delivery and other material terms relative to other potential or active manufacturers. If such bid is on substantially competitive terms with BioNumerik's other alternatives for manufacturing Product(s) for the Territory, then BioNumerik and ASTA Medica will negotiate in good faith to enter into a supply agreement providing for the manufacture by ASTA Medica of a portion of the Product(s) to be supplied for the Territory, which portion will be determined by BioNumerik. In the event of any unsuccessful bid by ASTA Medica, BioNumerik will describe to ASTA Medica the categories in which its bid was deemed not competitive. In the absence of any bid from ASTA Medica to manufacture Product(s) on substantially competitive terms to BioNumerik's other manufacturing alternatives, BioNumerik shall be free to utilize such other alternatives for the manufacture of Product(s) in the Territory.

17

The Supply Agreement will provide among other things that:

(a) Not later than the end of each calendar year that commences after execution of the Supply Agreement, ASTA Medica will supply to BioNumerik an estimate of its requirements of the amount of API or finished Product(s) in the Territory during the following [**] years, and will update this estimate at six-month intervals. BioNumerik will notify ASTA Medica within 90 days of receipt of such estimate if it (or its Affiliates) will be unable to supply the whole or any part of the requirements described in such estimate. Together with the [**] estimate, ASTA Medica will deliver to BioNumerik firm orders for its estimated requirements of Product(s) not less than 12 months in advance of the required date of delivery. Within thirty (30) days of its receipt of such firm order, BioNumerik shall confirm such order in writing and fulfill such orders in accordance with ASTA Medica's required date of delivery provided the quantities specified therein do not exceed those quantities contained in the previous estimate for the same period and provided that BioNumerik has not previously advised ASTA Medica that it will be unable to supply all or part of such quantities.

In such event, (i) BioNumerik shall grant a license to ASTA Medica under the BioNumerik Patent Rights, BioNumerik Know-How, and BioNumerik Improvements to manufacture and have such third party manufacture Product(s) for the purpose of allowing such remaining supply requirements to be filled, and (ii) BioNumerik shall also provide such information and reasonable assistance as may be necessary to allow such third party to manufacture Product(s) for the purpose of allowing such remaining supply requirements to be filled.

(c) The cost of the Product(s) under the Supply Agreement will be based on [**].

(d) ASTA Medica shall be entitled to have BioNumerik's cost of manufacture and overhead confirmed by an independent firm of accountants to which BioNumerik has no reasonable objection, but not more than once in any 12 month period, provided, however, that such firm of accountants shall only report to ASTA Medica the amount of such costs, including overhead, and shall keep confidential all other information acquired in the course of the examination. ASTA Medica shall pay the cost of any such audit and the audit shall be conducted so that it will not disrupt BioNumerik's ongoing business activities.

The Parties in good faith shall negotiate all other terms of supply and purchase to be included in the Supply Agreement.

7.5 No Infringing Manufacture or Supply. In any event, BioNumerik shall not be required to manufacture or supply Product(s) pursuant to this Agreement if by so doing it would be liable to suit for infringement or contributory infringement of the intellectual property rights of a third party.

In the event a Party receives an offer from an outside party or proposes to assign this Agreement to a Competitor, the assigning Party shall give the other Party written notice to such effect and, if requested by the non-assigning Party, the Parties shall negotiate for up to 60 days in an effort to reach agreement (i) that the proposed assignee is at least the equivalent of the assigning Party with respect to its fitness and ability to perform in accordance with the terms of this Agreement and (ii) that such assignment will not impair the reasonable business interests of the non-assigning party. If the Parties are unable to reach an agreement as to such matters, the non-assigning Party may terminate this Agreement upon 60 days written notice to the assigning Party following such assignment. In addition to and notwithstanding the foregoing, in the event the assigning Party is ASTA Medica, then BioNumerik may request and shall be granted a period (the "Evaluation Period") of up to 6 months following receipt of the written notice pursuant to this Section in which to make a determination as to whether or not to terminate this Agreement.

ATTACHMENT C

Set forth below are some examples of what are reasonable expected ranges for the pricing and sales prices for drugs in Japan - these ranges can vary from the examples given below:

1. [**] dose of drug is [**] the retail price to patient and government reimbursement.

2. Hospital or Pharmacy Purchase Price usually is about [**] respectively, [**]. The hospital or pharmacy will typically purchase a drug from a wholesaler or distributor, not directly from a manufacturer or pharmaceutical company.

3. Distributor or Wholesaler Price usually is about [**] of [**] - if the Venture or a third party owned by or affiliated with the Venture directly distributes and sells the drug, then the profit margin (above the Manufacturing Price and royalty) will be [**] between BioNumerik and GRELAN. The same would apply in the event that the Venture or a third party owned by or affiliated with the Venture directly distributes and sells the drug to a Hospital or Pharmacy.

4. Royalty is usually about [**] - this is [**] between BioNumerik and Grelan (e.g.: [**] paid to BioNumerik and [**] paid to Grelan).

5. Manufacturing Price for a contract manufacturer is estimated at about [**] - this is paid to the party that has manufacturing rights to the product and represents the price to manufacture the bulk drug [**] including fill and finish, label, store, record (adds another [**] and the margin of expected Manufacturer's profit (approximately [**] to the manufacturer.

Some scenarios for illustration of the foregoing:

a. The Venture drug sold is by third party distributor that has licensed the right to distribute, market and sell the drug in Japan. The [**] for the approved drug is [**] per unit. Grelan and BioNumerik would each receive [**] royalty payment [**] per unit) by the Japanese distributor. The total royalty that BioNumerik would receive from this would be [**] per unit.

b. In the above scenario, the Manufacturing Price for the Venture product is [**] (estimated at [**] BioNumerik would sell the drug directly to the third party distributor based on a [**] Manufacturing Price to be paid by the third party Japanese distributor. In this scenario, BioNumerik would also receive a manufacturing margin payment from the distributor of approximately [**]. In this scenario this would amount to approximately an additional [**] per unit. BioNumerik could also optionally sell the product directly to the Venture; in this scenario the manufacturer's profit margin would still be [**] and paid by the Venture to BioNumerik.

c. The Venture drug sold by Venture or a Venture-owned third party to distributor, wholesaler or hospital/pharmacy. The [**] for the approved drug is [**] per unit. The Manufacturing Price is [**] (based on [**]) and the price range that the drug is sold to distributor, wholesaler or hospital/pharmacy ranges from [**] The specific points of sale of drug units will be accounted for and payments will be made accordingly, with adjustment and reimbursement for any over- payment or under-payment to Grelan or BioNumerik for any units actually sold. Any profit margin resulting from the direct distribution or sale of the Venture product by the Venture or its affiliates would be paid to the Venture taking into account the Manufacturing Price (which is estimated to range from [**] this profit margin (meaning above that of any royalty and/or Manufacturing Price) would be [**] and paid to BioNumerik and Grelan from the Venture. BioNumerik shall also be paid a manufacturer's profit margin of approximately [**] for each unit. If there is any royalty payment, then this will be [**] between BioNumerik and Grelan as well. In this example, BioNumerik would sell the product to the Venture for [**] (Manufacturing Price of [**] plus Manufacturing Profit Margin of [**] plus [**] (the Wholesale/Distribution and Hospital or Pharmacy Price) per unit for a total of [**] per unit. The Venture would sell the unit to the distributor, wholesaler or hospital or pharmacy for [**] per unit and Grelan and BioNumerik would each be paid from the Venture a total amount of [**] per unit. If there is a royalty payment, then it shall be [**] between Grelan and BioNumerik and shall be part of the BioNumerik sales price of the product to the Venture.

[**] BioNumerik and Grelan will have certain rights to determine and establish prices for the Venture Products. The Manufacturing price for Venture Products BN will be established by BioNumerik and will include the costs for all raw materials and manufacturing along with the margin of profit for the manufacturer - this will be negotiated at the time of any third party license or will be established by mutual agreement in the event the Venture or an affiliate distributes and sells the products directly. The product royalty percentage will be established by BioNumerik and Grelan based on the license agreement with the third party distributor (e.g., a large pharmaceutical company) royalty obligations to the Venture. In the event the Venture or an affiliate decides to directly distribute or sell Venture products to a Japanese wholesaler/distributor, hospital or pharmacy the corresponding sales prices for each endpoint of sale will be jointly agreed upon by BioNumerik and Grelan for all Venture products in the territory of Japan. BioNumerik will have the sole right and authority to establish prices in all territories excluding Japan for all Venture Products BN, the rights to which are licensed to the Venture.

1.01  FORMATION

      The parties to this Agreement are members of the Company, a limited

liability company organized under the provisions of the Delaware Limited Liability Company Act, as amended from time to time (the "Act'). A Certificate of Formation (the "Certificate") was filed on September 20, 2000 with the Secretary of State of the State of Delaware. The Managers (defined in Section 2.01(a) hereof) may take such further actions as they deem necessary to permit the Company to conduct business as a limited liability company in any other jurisdiction.

1.02 NAME

The name of the Company shall be "KI Pharmaceuticals, L.L.C." The name of the Company may be changed from time to time by amendment of this Agreement and the Certificate pursuant to Section 1.07. The Company may transact business under an assumed name by filing an assumed name certificate in the manner prescribed by applicable law.

-1-

1.03 CONTINUATION AND TERM

The Company was formed upon the issuance by the Secretary of State of Delaware of a certified copy of the Certificate. The Company shall continue in existence until the close of the Company's business on December 31, 2030, or until the earlier dissolution of the Company pursuant to the provisions of this Agreement.

1.04 OFFICES

The principal office of the Company shall be determined from time to time by the Managers. The registered office of the Company required by the Act to be maintained in the State of Delaware, may be, but need not be, identical with the principal office. The Company's registered office, registered agent and the addresses thereof may be changed from time to time by the Managers in accordance with the Act. The Company may also have offices at such other places, both within and without the State of Delaware including Japan, as the Managers may from time to time determine.

1.05 NAMES AND ADDRESSES OF MEMBERS

The names and addresses of the Members are set forth on Schedule 1; provided, however, that if Dr. Hashime Kanazawa ceases to be a director, employee or statutory auditor of Grelan (as defined in 1.07 below) for any reason whatsoever, his Units in the Company shall be automatically assigned to Grelan and he shall cease to be a Member without the consent of any other Members or any other formalities notwithstanding any provision of this Agreement. He shall take appropriate steps necessary to ensure such assignment on or before the date of this Agreement and shall continue such steps in full effect during the term of this Agreement.

Subject to the provisions of this Article II, any one or more Managers may act for and on behalf of the Company and execute all agreements on behalf of the Company and otherwise bind the Company as to third parties without the consent of all of the Members. In addition to and not in limitation of any rights and powers conferred by law or other provisions of this Agreement, and except as limited, restricted or prohibited by the express provisions of this Agreement, the Managers shall have and may exercise on behalf of the Company, all powers and rights necessary, proper, convenient or advisable to effectuate and carry out the purposes, business and objectives of the Company. The Managers will have general and active supervision and direction over the day-to-day business operations of the Company and over its officers and employees.

(b) The Managers acting on behalf of the Company shall be reimbursed for their expenses incurred in carrying out their duties on behalf of the Company, but no salary or related compensation shall be payable to them in their capacity as Managers.

(c) In exercising their powers, the Managers may (i) rely upon and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, or document believed by them to be genuine and to have been signed or

-3-

presented by the proper party or parties; (ii) consult with counsel, accountants or experts selected by them and any opinion of an independent counsel, accountant or expert shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by the Managers in good faith and in accordance with such opinion; and (iii) execute any of their powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys.

2.02 LIMITATIONS ON THE MANAGERS' AUTHORITY

The Managers shall have no authority to do any act prohibited by law or in contravention of this Agreement, nor shall the Managers have any authority to do any of the following without the prior written consent of the Members holding more than three-fourths (3/4) of the outstanding Units:

(a) permit or cause the Company to make any loan to any Manager or Member or any Affiliate of a Manager or Member;

(b) permit or cause the funds of the Company to be comingled with the funds of any other Person;

(c) permit any creditor who makes a nonrecourse loan to the Company to acquire, at any time as a result of making such loan, any direct or indirect interest in the profits, capital or property of the Company other than as a secured creditor;

(d) perform any act which would impair or make impossible the ordinary conduct of the Company's business;

(e) sell, lease, exchange or otherwise dispose of all or substantially all of the assets of the Company, with or without goodwill other than in the ordinary course of business;

(f) merge or consolidate the Company with any other entity;

(h) permit or cause the Company to borrow money from any Person other than any Member;

(i) permit or cause the Company to guarantee for the benefit of any Person or to create a mortgage or any other encumbrance on any of the assets of the Company for the benefit of any Person;

-4-

(j) permit or cause the Company to use its property to redeem an Interest;

(k) permit or cause the Company to acquire any share or interest in any company, business or partnership; or

(l) permit or cause the Company to acquire land, buildings or movable fixed assets.

2.03 INDEMNIFICATION OF A MANAGER

(a) A Manager shall not be liable to the Company or any Member for any act or omission based upon errors of judgment or other fault in connection with the business or affairs of the Company if the Managers (other than the Manager seeking indemnification) determine that such course of conduct was in the best interest of the Company and did not result from the gross negligence or willful misconduct of such Manager.

(b) To the fullest extent permitted by law, a Manager shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, settlements and other amounts ("Losses") arising from any and all claims (including attorneys' fees and expenses, as such fees and expenses are incurred), demands, actions, suits or proceedings (civil, criminal, administrative or investigative), in which such Manager may be involved, as a party or otherwise, by reason of such Manager's management of the affairs of the Company, whether or not such Manager continued to be such at the time any such liability or expense is paid or incurred; provided that a Manager shall not be entitled to the foregoing indemnification if a court of competent jurisdiction shall have determined that such Losses resulted primarily from the gross negligence or willful misconduct of such Manager. The termination of a proceeding by judgment, order, settlement or conviction under a plea of nolo contendere, or its equivalent, shall not, of itself, create any presumption that such Losses resulted primarily from the gross negligence or willful misconduct of a Manager or that the conduct giving rise to such liability was not in the best interest of the Company. The Company shall also indemnify a Manager who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action by or in the right of the Company to procure a judgment in its favor by reason of the fact that such Manager is or was an agent of the Company, against any Losses incurred by such Manager in connection with the defense or settlement of such action; provided that no Manager shall be entitled to the foregoing indemnification if a court of competent jurisdiction shall have determined that any such Losses resulted from the gross negligence or willful misconduct of such Manager. The Company may advance a Manager any expenses (including, without limitation, attorneys' fees and expenses) incurred as a result of any demand, action, suit or proceeding referred to in this paragraph
(b) provided that (i) the legal action relates to the performance of duties or services by such Manager on behalf of the Company; and (ii) such Manager gives a full

-5-

recourse promissory note to the Company for the amounts of such advances payable in the event that such Manager is determined to be not entitled to indemnification hereunder.

(c) The indemnification provided by paragraph (b) of this Section 2.03 shall not be deemed to be exclusive of any other rights to which a Manager may be entitled under any agreement, as a matter of law, in equity or otherwise, and shall continue as to a Manager who has ceased to have an official capacity and shall inure to the benefit of the heirs, successors and administrators of such Manager.

(d) Any indemnification pursuant to this Section 2.03 will be payable only from the assets of the Company.

2.04 TRANSACTIONS WITH A MANAGER OR AN AFFILIATE OF A MANAGER

Subject to the provisions of Section 2.02, a Manager, on behalf of the Company, may enter into contracts with itself or its Affiliates, provided that any such transactions shall be on terms no more favorable to the Manager or such Affiliates than generally afforded to unrelated parties in similar transactions.

2.05 VOTING: QUORUM

Each Manager shall have one vote. A majority of the number of Managers fixed by this Agreement shall constitute a quorum for the transaction of business; provided, that if more than one Manager is appointed and less than a majority of the Managers are present at a meeting, a majority of the Managers present may adjourn the meeting from time to time without further notice. If a quorum is present when a vote is taken, the affirmative vote of a majority of the Managers present is the act of the Managers unless this Agreement requires the vote of a greater number of Managers.

2.06 STEERING COMMITTEE

(a) The Managers shall appoint a Steering Committee of the Company comprised of two members: one from among Grelan's senior officers or employees designated by Grelan and the other one from among BioNumerik's senior officers or employees designated by BioNumerik.

(b) shall apply mutatis mutandis to any payment to them for conducting their duties as such members of the Steering Committee. Each Steering Committee member must also be a Manager.

(b) No Steering Committee member shall be removed and no new Steering Committee member shall be appointed unless such removal or appointment is consented to by both Grelan and BioNumerik, acting in their capacity as Members.

2.07 OFFICERS

(a) President, Chief Executive Officer and Secretary. If the Members holding more than two-thirds (2/3) of the outstanding Units deem it necessary or appropriate, they may elect a President, a Chief Executive Officer ("CEO"), and/or a Secretary; provided that the President and the CEO always must be the Managers concurrently.

Sections 3.01 (c), and 3.02 to 3.04 shall also apply mutatis mutandis with respect to the term of office, designation rights, resignation or removal of the office as President, CEO and Secretary. The President, the CEO and the Secretary, if any, acting on behalf of the Company shall be reimbursed for their expenses incurred in carrying out their duties on behalf of the Company, but no salary or related compensation shall be payable to them.

(b) Subordinate Officers. The Managers may appoint such officers (other than the President, CEO and Secretary) as they deem necessary. One (1) person may hold any two (2) or more of these offices. The Managers shall appoint such other officers, in principle, at their first meeting after each annual meeting of Members.

(d) Removal of Subordinate Officers. Any officer (other than the President, CEO and Secretary) may be removed at any time with or without cause by the affirmative vote of the Members holding two-thirds (2/3) of the outstanding Units. The removal of any officer shall be without prejudice to the contract rights, if any, of the person so removed. Election or appointment of such officer shall not of itself create any contract rights, merely by virtue of such election or appointment.

-7-

(e) Vacancies of Subordinate Officers. A vacancy in any officer (other than the President, CEO and Secretary) shall be filled for the unexpired portion of the term by the Managers.

(f) Salaries of Subordinate Officers. The salary or compensation of officers (other than the President, CEO and Secretary), if any, shall be established from time to time by the Managers. The Managers may delegate to any committee or officer the power to fix from time to time the salary or other compensation of officers (other than the President, CEO and Secretary) appointed in accordance with the provisions of this Article.

No Member shall be entitled to interest on any Capital Contribution or on such Member's Capital Account.

4.03 COMPROMISE

                                   ARTICLE V
                         ALLOCATIONS AND DISTRIBUTIONS

5.01  CAPITAL ACCOUNTS

      The Company shall maintain in its books and records, in accordance with

Section 1.704-1(b)(2)(iv) of the Treasury Regulations, a capital account for each Member and Assignee (a "Capital Account"). Each Member's Capital Account shall be increased by (1)(a) the amount of money contributed by such Member to the Company, (b) the fair market value of property or other consideration contributed by such Member to the Company (net of liabilities secured by such contributed property that the Company is considered to assume or take under
Section 752 of the Code), and (c) allocations to such Member of Company income and gain (or items thereof), and is decreased by (2)(w) the amount of money distributed to such Member by the Company, (x) the fair market value of property or other consideration distributed to such Member by the Company (net of liabilities secured by such distributed property that such Member is considered to assume or take under Section 752 of the Code), (y) allocations to such Member of expenditures of the Company described in Section 705(a)(2)(B) of the Code, and (z) allocations of Company loss and deduction (or items thereof). For purposes of this Article, a Member who has more than one Interest in the Company shall have a single Capital Account that reflects all such Interests, regardless of the class of Interests owned by such Member and regardless of the time or manner in which such Interests were acquired. All Capital Accounts are to be determined in accordance with the rules set forth in Section 1.704-1(b)(2)(iv) of the Treasury Regulations.

5.02 ALLOCATION OF PROFITS

The Profits of the Company shall be allocated to the Members as follows:
(a) [**] to Grelan, (b) [**] to BioNumerik, and (c) [**] to Dr. Hashime Kanazawa.

(a) [**] to Grelan, (b) [**] to BioNumerik, and (c) [**] to Dr. Hashime Kanazawa.

5.05 SPECIAL ALLOCATIONS TO CAPITAL ACCOUNTS

The Capital Accounts of the Members are to be maintained in accordance with the Code and the Treasury Regulations, including without limitation the alternative test for economic effect set forth in Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations and the minimum gain chargeback provisions of
Section 1.704-2 of the Treasury Regulations. Nothing in this Agreement is intended to create a deficit restoration obligation or otherwise impose personal liability on a Member for a deficit in its Capital Account. Without limiting the generality of the foregoing:

(a) If an allocation of loss or other allocation pursuant to Section 5.04 hereof including expenditures described in Section 705(a)(2)(B) of the Code would cause or increase a deficit in a Member's Capital Account as defined in
Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations and Section 1.704-2 of the Treasury Regulations, then the amount of the loss or other allocation which would have caused or increased a deficit in a Member's Capital Account shall be allocated instead to the Capital Account of the other Members which would not have a deficit in their Capital Accounts as a result of the allocation, in proportion to their respective Interests, or, if no such Members exist, then to the Members in accordance with their allocation of Profits pursuant to Section 5.02 hereof.

(b) If any Member unexpectedly receives any adjustments, allocations, or distributions described in Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6) of the Treasury Regulations, which create or increase a deficit in such Member's Capital Account, the items of the Company's income and gain for such year and, if necessary, for subsequent years shall be specially credited to the Capital Account of such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the deficit in the Capital Account as quickly as possible. Any such allocations shall be made pro rata. It is the intent that this section be interpreted to comply with the alternate test for economic effect set forth in Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations.

(c) Income and gain attributable to Venture Products BN Activities shall be allocated [**] to the Members, in accordance with their respective Percentage Interests for Venture Products BN Activities.

(d) Income and gain attributable to Venture Products GR Activities shall be allocated [**] to the Members, in accordance with their respective Percentage Interests for Venture Products GR Activities.

(e) Operating costs of the Company for any taxable year shall be allocated [**] to Grelan (up to a maximum of U.S. [**] per year) until such time that product revenues are obtained from Venture Products.

     Upon the signing of this Agreement by the Parties, RPS will undertake
     receipt of the technology transfer from BioNumerik and laboratory
     familiarization with the BNP7787 process as necessary to prepare the
     Compound in accordance with the Specifications, all as described in the
     Project Description (the "Project Description") attached hereto as Annex 1.
     The price for this Phase 1 material will be as described in the Project
     Description attached hereto as Annex 1 to be paid as described in Section
     2.3 hereof.

         (b) Phase 2 - Site Qualification.

     Upon successful completion of Phase 1 and following receipt of written
     authorization from BioNumerik to proceed with Phase 2, RPS will complete

     (cGMP) a number of [**] target batch size qualification batches in order
     to assure meeting the critical success criteria (the "Success Criteria")
     included in Annex 10 hereto. Should the first qualification batch be
     prepared under conditions deemed successful based on the Success Criteria,
     then the second batch may be eliminated and BioNumerik shall only be
     required to pay for such first batch. Should more than two batches be
     required in order to meet the Success Criteria, all batches prepared in
     excess of the first two batches will be done so at the expense of RPS
     without additional cost to BioNumerik. The price for these Phase 2 batches

batches as described in the Project Description. The price for these Phase 3 batches will be as described in the Project Description attached hereto as Annex 1 to be paid as described in Section 2.3 hereof.

(d) Phase 4 - Commercial Batches.

Upon successful completion of Phase 3, RPS will prepare under cGMP commercial batches of the Compound with quantities and delivery schedule to be agreed between BioNumerik and RPS. The price for the commercial batches will be as described in the Project Description attached hereto as Annex 1. It is expected that if BioNumerik gives RPS [**] prior notice of a need for a commercial batch, RPS will do its best to fulfill the order within such time frame. However, RPS cannot guarantee delivery of Compound [**] prior notice, but in any event RPS will deliver Compound within a maximum of six months after notification by BioNumerik, except in the event of an occurrence of a Force Majeure event described in Section 9.4.

2.2 (a) All Compound shall be manufactured and delivered in accordance with the Compound Specifications indicated in Annex 2. These Specifications will be obtained from BioNumerik, or will be developed in conjunction and with the approval of BioNumerik. Any changes in the Specifications will be agreed between BioNumerik and RPS prior to scale-up or commencing the production. In addition, manufacturing of all Compound by RPS (other than Compound manufactured as part of the Phase 1 Work) will be conducted in compliance with relevant current U.S. Food and Drug Administration ("FDA") Good Manufacturing Practices ("cGMP") and International Conference on Harmonisation ("ICH") guidelines.

(b) Unless otherwise already specified in the Annexes hereto, the batch records; specifications for raw materials, intermediates and final products; and analytical test methods for all materials will be delivered to RPS by BioNumerik subsequent to the signing of this Agreement or BNPI will develop in conjunction with RPS any additional requirements. All batch records and production documentation specific to the Compound must be approved in writing by BioNumerik prior to use. Any changes in the production flow steps, analytical methods, production records, test methods, Specifications, or equipment used by RPS will require prior written approval by BioNumerik. RPS will provide a Certificate of Analysis and executed batch record with each shipment that describes product specifications and results.

(c) All starting material and other raw materials necessary for the work hereunder will be supplied by RPS without additional charge to BioNumerik. RPS will have back-up starting material and raw materials available should BioNumerik decide to proceed with an additional batch of Compound in the event a batch fails. If a batch fails to meet Specifications due to factors under the control of RPS or is rejected by BioNumerik or

[**] CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.


RPS due to critical failure to be manufactured in accordance with cGMP, and BioNumerik requests RPS to manufacture an additional batch of Compound or reprocess the batch that is out of specification ("OOS"), then RPS will conduct such manufacturing or reprocess at no additional charge to BioNumerik and will schedule the manufacture of such additional batch of Compound as soon as practical (and in any event within 30 days of BioNumerik's request, unless the manufacture within such time period is prevented by catastrophic equipment failure or other Force Majeure event described in Section 9.4). The specifications of the starting materials for manufacture of the Compound are as set forth on Annex 3 to this Agreement.

(d) Procedures for release of the Compound have been agreed to by BioNumerik and RPS and are attached on Annex 5 hereto. The procedures to be followed upon the occurrence of an Out of Specification (OOS) or Out of Trend (OOT) event are contained in the standard operating procedures (SOPs) for the RPS [**] facility. Current copies of such SOPs have been previously provided by RPS to BioNumerik and RPS will promptly provide BioNumerik with any changes to such SOPs. These procedures contain specific timelines for investigation of OOS and OOT events. Timelines to be followed for a batch failure due to circumstances other than OOS and OOT events are also contained in the SOPs for the RPS Annan, Scotland facility. RPS will retain samples of each API batch of Compound and samples of all solid raw materials and intermediates used in the manufacturing for a period of at least 5 years following completion of the manufacturing, provided that commodity solid raw materials will be maintained for a period of at least one month following completion of the manufacturing.

(e) RPS shall be responsible for conducting an audit program for vendors (including testing facilities) utilized by RPS in connection with manufacturing of the Compound as required to comply with cGMP and ICH Guidelines (including ICH guideline Q7A). RPS will provide BioNumerik with a copy of RPS' audit procedures and analytical approval process, and any updates or amendments to such procedures and process. BioNumerik has the right, during any audits of RPS conducted by BioNumerik, to review the records for all raw material and starting material vendor audits conducted by RPS with respect to raw materials and starting materials (as defined by ICH guidelines) for the Compound. In addition, BioNumerik shall also have the right to review the qualification records (as required by cGMP) of the vendors for the starting materials for the Compound, provided the starting materials are produced under cGMP. RPS shall promptly inform BioNumerik in the event of a concern with the quality or manufacturing compliance with respect to a raw material used in the manufacture of the Compound and RPS will coordinate with BioNumerik to assure a prompt resolution of any such concern. The results of all audits that have occurred that relate to the materials to be used in the manufacture of the Compound have previously been provided to BioNumerik, and RPS will promptly provide to BioNumerik the results of

                  acquired, directly or indirectly, from the disclosing Party;
                  or

         d)       Confidential Information which a receiving Party shall receive

8        INTELLECTUAL PROPERTY RIGHTS

8.1      a) As used herein "Intellectual Work Product" means all inventions,
         modifications, discoveries, improvements (including, without
         limitation, process improvements and improvements in analytical
         methods), processes, techniques, documentation, scientific and
         technical data, drawings and other information (other than the RPS
         Technology) that is generated as a result of any of the manufacturing
         services and other projects performed for BioNumerik by RPS. "RPS
         Technology" means all present and future documentation, scientific and
         technical data, processes, test procedures and other information and
         techniques that are owned, developed or licensed by RPS relating to the
         development, formulation or manufacture of chemical and pharmaceutical
         substances and that are not developed hereunder or in connection with
         the manufacturing or other projects performed for BioNumerik by RPS.
         BioNumerik shall not own any of the RPS Technology. RPS will, however,
         use know-how and experience of RPS to facilitate the efficient
         manufacture of the Compound.

         b) The parties hereto understand and agree that no rights are being
         conveyed to RPS (or any of their affiliates) to use any BioNumerik
         Technology (as hereafter defined) for any purpose other than the sole
         purpose of preparing the Compound for the benefit of BioNumerik in
         accordance with the terms of this Agreement. As used herein,
         "BioNumerik Technology" means all present and future documentation,
         scientific and technical data, processes, test procedures, information,
         techniques, technology, patents, patent rights, inventions and other
         intellectual property rights that are owned, developed, or licensed by
         BioNumerik.


8.2      a) RPS acknowledges that BioNumerik shall be the sole and exclusive
         owner of all Intellectual Work Product (except the RPS Technology, as
         described above in Section 8.1). In consideration of the covenants
         contained herein, and for other good and valuable consideration set
         forth herewith, RPS hereby assigns and transfers to BioNumerik and its
         successors and assigns all right, title and interest that RPS has or
         may later acquire in and to the Intellectual Work Product under
         copyright, patent, trade secret and trademark law. Such assignment
         includes the assignment of the entire right, title and interest in and
         to all applications for letters patent and any and all letters patents
         in the United States of America and all foreign countries which may be
         granted on and in connection with the Intellectual Work Product. Upon
         request by RPS, BioNumerik will meet with RPS to discuss the
         possibility of providing RPS with a non-exclusive, royalty free,
         non-sublicensable license to practice the Intellectual Work Product
         described in 8.1(a) above for the purpose of manufacturing compounds
         other than the Compound that are not similar to or related to the
         Compound and that do not complete in any way with the business and
         planned business of BioNumerik or BioNumerik's strategic alliance
         partners. BioNumerik will have no obligation to grant such a license
         and any determination to grant such a license will be made in the sole
         discretion of BioNumerik and will be based upon such considerations as
         BioNumerik deems appropriate.


         b) RPS agrees to cooperate with BioNumerik so that BioNumerik may enjoy
         to the fullest extent the entire right, title and interest in and to
         the Intellectual Work Product. In connection therewith, RPS agrees to
         execute, if necessary, additional papers and documents and to take all
         actions requested by BioNumerik in order to (a) further evidence
         ownership of the Intellectual Work Product by BioNumerik and its
         successors and assigns and (b) allow BioNumerik to procure, maintain
         and enforce all letters patent and intellectual property rights to the
         Intellectual Work Product. BioNumerik agrees to reimburse RPS all
         reasonable costs in relation to the production of additional papers and
         documents.

         c) In addition, for the purpose of the work conducted by RPS for the
         BNP7787 manufacturing project as described in the Project Description,
         RPS will not incorporate any of its proprietary technologies toward a
         synthesis or manufacturing process.

         d) RPS is hereby granted a worldwide, nonexclusive, royalty-free
         license to practice the Intellectual Work Product solely for the
         purpose of preparing Compound on behalf of BioNumerik in accordance
         with this Agreement and the Project Description.

         e) BioNumerik warrants and represents that the Products manufactured
         and delivered by RPS under this Agreement will be used solely by

         BioNumerik or its designated assignees, licensees, representatives or
         alliance partners for legally permissible purposes. BioNumerik further
         represents and warrants that it has the right to disclose its
         Confidential Information to RPS, including without limitation all
         technology made available by BioNumerik to RPS for the manufacture of
         the Compound subject to and in accordance with the provisions of this
         Agreement, and that BioNumerik has the right to license such technology
         to RPS for such purpose and RPS may use it accordingly, all free and
         clear of any intellectual property or other rights of third parties,
         all subject to and in accordance with the provisions of this Agreement.

8.3      Except as specifically described in this Agreement, no right, title,
         interest, or license in or to any trademark, patent, copyright or
         service mark or symbol or any other intellectual property right of a
         party is granted to the other party under this Agreement.

         further that RPS will not indemnify or hold harmless Indemnified
         BioNumerik Parties for any losses arising out of BioNumerik's
         negligence.

         obligations of either Party to the other Party under this Agreement,
         the following conditions must be met for such indemnification
         obligations to become applicable:

         a) The indemnified Party shall notify the indemnifying Party promptly

         manufacture of the Compound, it simply cannot make the Compound
         required for future phases of this Agreement within the Specifications
         (as defined in this Agreement), such written notice to include an

1. EXECUTIVE SUMMARY

BioNumerik Pharmaceuticals, Inc. ("BioNumerik") is currently in development with BNP7787, also known as Tavocept(TM), a chemoprotectant intended for use to neutralize the toxic side-effects of a number of major anticancer drugs - including platinum and taxane drugs. Currently BioNumerik has established a long-term supply agreement with Sumika of Japan, but is interested in securing a second supplier. The FDA has recently given BNP7787 fast-track designation, and the clinical trial program for BNP7787 is currently in Phase III. BioNumerik has requested Rhodia Pharma Solutions Inc. ("RPS") to provide price and timeline estimates for lab evaluation/tech transfer, qualification batches, validation batches, and commercial batches of BNP7787.

RPS has considered the above requests and offers the following proposal based on the technical data and requirements supplied by BioNumerik. A firm timeline for the activities described will be provided after approval and suitable discussions between RPS and BioNumerik.

RPS proposes a four-phase project (the "Project") to be conducted at RPS'
[**]facility:

Phase 1: Lab familiarization, tech transfer, and hazard evaluation Phase 2: Qualification campaign (up to 2 x [**]) Phase 3: Validation campaign (3 x [**]) Phase 4: Commercial batches

RPS has agreed that the price for Phase 1 of the project on a [**] will be:

Phase 1: Lab familiarization/Tech transfer [**]

[RHODIA LOGO]

RPS has agreed that the price for Phases 2-4 of the project on a [**] will be, subject to the other provisions of this Proposal and to the terms and conditions contained in the Agreement for Manufacturing and Supply of BNP7787 between RPS and BioNumerik (the "Agreement"), to which Agreement this Proposal is attached as Annex 1:

Phase 2:  Qualification campaign                              [**]

Phase 3:  Validation campaign                                 [**]

2. PROPOSAL

The process used to prepare BNP7787 is shown below:

SCHEME 1. SYNTHESIS OF BNP7787

Proposal #ANNJMC20021211-A November 7, 2003 Page 5 of 17


[RHODIA LOGO]

RPS will conduct the Project in the phases described below:

PHASE 1: TECHNOLOGY TRANSFER AND FAMILIARIZATION

BioNumerik developed and scaled this process in-house before entering into BioNumerik's agreement with Sumika. As part of transferring the process to RPS, there are several necessary activities.

RPS would expect to receive copies of all batch records and process development / hazard evaluation reports for review along with analytical standards, markers, and analytical methods used in the manufacturing process. This will allow the technical team from RPS to become familiar with the process and permit the analytical method transfer to commence. A technical exchange with a team from BioNumerik originally involved in the development /operation of this process would allow RPS to assess and highlight to BioNumerik any significant deviations from the original scope before commencing manufacture.[**].

NOTE: Should the tech transfer information received from BioNumerik be, in RPS' opinion, insufficient to enable RPS to safely and efficiently transfer the process to the RPS plant, a new work plan going forward will be discussed (including tasks and appropriate charges) and agreed by RPS and BioNumerik with the goal of getting the process into the plant.

RPS has sourced raw material suppliers. If so desired, BioNumerik may wish RPS to procure raw materials from these suppliers or find other suppliers.

[RHODIA LOGO]

PHASE 2: SITE QUALIFICATION

Based on the process flow sheet, BioNumerik's preferences, and the need to isolate an API at scale in a Class 10,000 isolation area, [**] is the site of choice for qualification with respect to the Project. RPS believes that the BioNumerik process is a good fit for the A3 plant at [**]. This site has also been considered as the site that could accommodate the possible manufacture of up to [**] of BNP7787 if desired by BioNumerik in the future.

After completion of Phase 1, the following qualification strategy would be implemented (timing subject to change based on BioNumerik's strategic plan):

- Qualification campaign - cGMP preparation of up to 2 batches of approximately [**] each to be used to support Phase III clinical trials. [NOTE: should RPS feel that more than two batches of BNP7787 need to be prepared to meet the acceptance criteria, all batches prepared above and beyond the first two will be prepared at RPS' expense]. Target batch size is [**]. Development necessary to support the campaign is included in Phase 1. Should the first batch be prepared under conditions deemed successful based on critical success criteria (included in Appendix 10 to the Agreement), the second batch may be eliminated. Pricing for this work will be [**] with a maximum BioNumerik spend of [**] for the total qualification material.

Hazard Evaluation studies would also be undertaken by RPS to ensure the process will be as safe as possible during scale-up.

As BioNumerik will require [**] of stability data prior to initiation of the NDA submission, RPS has the option of generating material in 2004 with a view toward obtaining [**] stability data which would satisfy BioNumerik's timeline and which could be included with the BNP7787 submission document (currently estimated for as early as approximately [**]. This program of work is based on the expectation of carrying out full stability studies (5-year study to ICH guidelines) on the final API (BNP7787). The assumption is that there will be no intermediate stability studies required since this is a "one-pot" process where no intermediates are isolated.

Details of the 2 x [**] qualification campaign are summarized below.

PHASE 3: VALIDATION BATCHES

Upon successful completion of the 2 x [**] batch qualification campaign, RPS would then validate the process according to BioNumerik's timeline. RPS will prepare three validation batches of [**] each to prepare a total of approx.
[**]. Target batch size is [**] RPS will endeavor to complete the three validation batches during late [**] but cannot guarantee the precise timing. In the event RPS is not able to prepare such batches by late [**], RPS will so advise BioNumerik and RPS will then work expeditiously to complete such batches as soon thereafter as reasonably possible within a time-frame described to and coordinated with BioNumerik. Before these are initiated, however, an additional round of development work may be required to address any issues identified in the process after the qualification campaign. The effect of these changes and their impact on registration would need to be agreed between RPS and BioNumerik before any additional work by RPS occurred.

Pricing for the Phase 3 validation batches will be [**] and BioNumerik will be invoiced for this work in [**], with payment deferred until [**]. An additional [**] will be charged for chemist support for the validation campaign. BioNumerik will be invoiced for this chemist support work in 2004, with payment expected in [**].

Details of the validation campaign are summarized below.

PHASE 4: COMMERCIAL BATCHES

Following successful completion of the validation campaign, RPS would progress the process to commercial scale with the capability of preparing
[**][**] and [**] commercial batches based on such amounts as BioNumerik may request in the future. Details for these commercial batches are summarized below (potential amounts for illustration purposes only).

[**]

Note: Based on BioNumerik's requirements, RPS can offer flexibility in batch size. Batch sizes of [**] and [**] can be generated at BioNumerik's request. In order to achieve the [**] batch size, RPS suggests two options:

- Two successive [**] batches would be combined on a large Rosenmund filter, then slurried together to form the [**] batch.


- Replacement of key vessels to allow the preparation of a discrete
[**] batch.

KEY ASSUMPTIONS:

- The process will operate in line with the batch records supplied (when available) in terms of processing time and yields.

- Validated analytical methods will be supplied during the technical transfer.

- Markers and reference standards will not have to be synthesized.

- Raw materials are readily available from sources identified to date and safe to handle.

- 50 Kilogram heel loss on the Rosenmund vessel is assumed.

- Microbiological analysis will be conducted offsite at a rate of [**] Endotoxin testing will be conducted onsite using a purchased-in kit.

- The high bromide and sulfur content of the aqueous waste stream will necessitate offsite incineration. Guideline disposal price is [**] waste.

- Target prices for sodium 2-bromoethanesulfonate and thioacetic acid are achievable.

The actual charges for BioNumerik's account will be invoiced as described in the Manufacture and Supply Agreement, with payment due net 30 days from invoice date. A down payment as described in the Manufacture and Supply Agreement is due upon acceptance of this proposal. This payment will be used to purchase starting materials, with any balance credited towards the final billable work performed on this project. All deliveries will be FOB, U.S.A. main port basis. Shipments will be made by air unless otherwise agreed by RPS and BioNumerik.

Prior to the start of the Phase 2 qualification campaigns, the A3 plant must be re-engineered to accommodate the process. RPS estimates it will take approximately four months to effect the engineering work and to complete the validation of the USP water system in A3. The majority of the engineering work will be required to handle the pure water system and pressurized oxygen. The specifics of the re-engineering process can be summarized as follows:

ITEM

Pure water ring main installation and tie in to three units Oxygen gassing station
Transfer lines, tracing, lagging, & flow control, support Design and Maintenance support Electrical & Instrumentation

[RHODIA LOGO]

CAPITAL RECAPTURE CLAUSE

RPS' goal is to supply approximately [**] of BNP7787 prepared and delivered at commercial scale under cGMP conditions over a period of approximately [**]. We hope that this will be followed by a launch stock order of at least [**] RPS will provide the approximately [**] in capital spend required to fit the process into our plant. This plan allows RPS to spread out our internal capital spend over enough batches to allow us to offer BioNumerik close to commercial pricing for qualification and validation batches. Should BioNumerik decide to change the scope of the project and order less than [**] total within [**] after the effective date of the Agreement (including qualification, validation, and commercial batches), RPS will attach a capital recapture fee of [**] for the difference in what was ordered and [**] plus an additional [**] to cover the discount on the Phase I work (reduced from [**]), up to a maximum capital recapture fee and additional payment of [**] in the aggregate to be paid by BioNumerik. A worked example is displayed below. In addition, the amount of any recapture fee and additional payment paid by BioNumerik to RPS pursuant to the foregoing provision shall be fully credited against and applied to the satisfaction of the cost of any order for Compound made by BioNumerik within six months after payment of such recapture fee and additional payment. Of course, in the event that the project proceeds as expected and a minimum of [**] is ordered (including qualification, validation, and commercial quantities), no additional charge is payable since all capital expenses are amortized over the campaign.

EXAMPLE:

BioNumerik cancels the project having ordered a total of [**] including qualification, validation, and commercial quantities.

Material delivered to date: [**]

Minimum total order required: [**]

1.0 INTRODUCTION

This procedure applies to all final products made at Rhodia Pharma Solutions,
[**]. It specifies how batches are off-loaded, sampled, labelled, analysed and sentenced.

2.0 DEFINITIONS

QC - Quality Control
OQ - Operational Quality

3.0 RESPONSIBILITIES

See details within the individual parts of the procedure section.

4.0 PROCEDURE

4.1 MANUFACTURING ACTIVITIES

Manufacturing inform the Quality Department when a batch of final product is to be off-loaded. The Quality Department reserve the right to be present during off-loading to ensure that the correct procedures are followed.

Final product is off-loaded under controlled conditions via suitable off-loading equipment e.g. glove-box, containment booth or cleanroom. Specific sampling and off-loading requirements for each product are detailed in the relevant manufacturing logsheet/manufacturing guide. The samples are clearly labelled and delivered to the QC department for analysis.

When off-loaded, the filled containers have a unique sequentially numbered product label attached to them by manufacturing which specify the identity, batch number, container number, gross, Tare and nett weights.

Following offloading and sampling, the containers are sealed by manufacturing using uniquely numbered metal security seals. The seal numbers are recorded on the ancillary logsheet. The containers are then transferred to the S12 warehouse, or the drum park as appropriate. The logsheet is signed to indicate that the off-loading activities are complete. Note: should a container need to be re-sampled it will be checked for cleanliness and returned to the off-loading area. Sealed containers may only be opened with the permission of the OQ Department in line with POP 01/00.

Manufacturing enters the batch weight into SAP, which automatically transfers the batch to QI status.

4.2 ANALYTICAL ACTIVITIES

On receipt of the product samples from manufacturing, QC will designate (as labelled) one sample as a keeping sample, which will be stored for possible future reference.

The QC analyst will then generate "inspection Instructions" from SAP and the remaining sample will be analysed according to the correct method reference. Note that if an MGA is operative, extra testing may be required (see ASOP015C/007 - Manufacturing Guide Amendment Procedure).

ASOP008C/057 REV 1 Page 4 of 8

As the analytical tests are carried out the results are calculated and then checked by a second person. Test results will be evaluated against an approved specification. Any tests, which fail to meet the defined acceptance criteria, are dealt with in accordance with SOP016A/001 - Out of Specification Procedure.

When analysis on the batch is complete, the results are entered onto the SAP system. An Inspection Report is then generated by SAP, signed by the analyst and the data checked by a second person. The analyst, checker or third person signs to indicate that the analysis has been completed correctly.The inspection report is then passed to Operational Quality.

4.3 OQ ACTIVITIES

The correct usage decision (or sentence) for any batch depends on both its manufacturing history and analysis. Rhodia Pharma Solutions Operational Quality are responsible for carrying out the checks specified below and for ensuring that the correct usage decision is made.

OQ carry out the following checks:

- Check batch documentation in line with the requirements of the relevant part of ASOP008F/002. If satisfactory, sign the SAP Inspection Report to indicate that the manufacturing documentation has been completed correctly.

- Check whether the batch was subject to an MGA and confirm that all outstanding actions which impact the usage decision have been assessed and closed out.

- Confirm that any records associated with the manufacture of the batch are present, e.g. in-process analysis.

- Review any PDRs associated with the batch and assess their impact on the usage decision with particular reference to the likely impact on quality, any violations of regulatory submissions and impact on validation and critical parameters.

- Ensure that the analytical data and inspection report are available and have been reviewed and approved by the Analytical Department.

- Check whether the batch is within specification.

- Review any Out of Specification Reports and ensure that a full and thorough investigation has been made and the correct conclusions drawn.

- If the batch is out of specification ensure an OOSIR has been completed (see above). Also, ensure that a process investigation report (PIR) has been completed, which identifies the cause of the failure, corrective action to prevent recurrence and which recommends from a technical viewpoint how the batch should be sentenced. Assess the regulatory, validation and cGMP aspects of such a recommendation prior to making a usage decision. OQ sign off the PIR.

- Inform the customer of significant deviations/issues as required by the relevant agreements.

- Ensure that any issues affecting inputs to the batch are fully accounted

for.


ASOP008C/057 REV 1 Page 5 of 8

The Operational Quality Manager then sentences the batch, taking into account all of the above information. The correct usage decision is entered on the SAP inspection report and the report then signed and dated. The Operational Quality manager then enters the usage decision into SAP.

A batch release checklist is used to facilitate and record the OQ checking associated with each batch of final product. (See Appendix 1).

Analytical data is available to Manufacturing via the SAP system. The Inspection Instructions, computer output and ancillary logsheet are filed in the Quality Department archives.

2                 MANUFACTURE AND SUPPLY OF COMPOUND


2.1               Subject to the provisions of this Agreement, BioNumerik shall
                  purchase from Sumika and Sumika shall supply, at the price set
                  forth in Annex 2 attached hereto, a minimum of [**] of
                  BioNumerik's annual actual requirements of the Compound until
                  the cumulative total amount of the Compound purchased by
                  BioNumerik from Sumika reaches [**]. BioNumerik may also
                  consider additional procurements of its Compound from other
                  manufacturers in accordance with Section 2.3.



2.2               The Compound shall be manufactured and delivered in accordance
                  with the Compound Specifications indicated in Annex 1, which
                  will be mutually updated from time to time by the Parties. In
                  addition, manufacturing of the Compound by Sumika will be
                  conducted in compliance with current U.S. FDA Good
                  Manufacturing Practices (cGMP), ISO9002 and International
                  Conference on Harmonization (ICH) regulations and guidelines.
                  BioNumerik shall not export the Compound sold by Sumika
                  hereunder or the Product(s) produced from such Compound to any
                  country or territory where such export would be in violation
                  of the patent laws of such territory. Prior to any export of
                  Compound(s) or Product(s), BioNumerik and Sumika shall, if
                  requested by either party, discuss in good faith the matter of
                  whether such export would violate the patent laws of the
                  intended country or territory of export. In addition to the
                  foregoing, BioNumerik shall have no obligation to purchase
                  from Sumika any percentage of its requirements of Compound
                  with respect to a territory to which it is unable to export
                  Compound as provided in the Section 2.2 or to which Sumika
                  does not agree to export Compound as provided in Section 2.9.
                  Sumika will not sell the Compound to any party other than
                  BioNumerik without BioNumerik's prior written consent.


                  Sumika shall be entitled to appoint any trading company it
                  deems appropriate to act as an intermediary between the
                  Parties for the purchase, sale and delivery of the Compound,
                  provided that the costs paid or payable by BioNumerik shall
                  not increase because of such appointment and such trading
                  company shall be reasonably acceptable to BioNumerik.

2.3               In the event BioNumerik considers procurements of its Compound
                  in addition to the amount (a minimum of [**] of BioNumerik's
                  annual actual requirements of the Compound until the
                  cumulative total amount of the Compound purchased by
                  BioNumerik from Sumika reaches [**] to be purchased pursuant
                  to Section 2.1, BioNumerik may conduct such additional
                  procurements from other manufacturers, provided BioNumerik
                  shall give Sumika notice of such consideration prior to any
                  farther contracting with another supplier or suppliers for
                  such additional Compound amounts. In such circumstances,
                  Sumika may, a its option, provide BioNumerik with a bid
                  containing new price, delivery amount and other material terms
                  under which it would manufacture and transport Compound on a
                  non-exclusive basis to BioNumerik. It is the hope of the
                  Parties that Sumika will manufacture A significant and major
                  portion of the Compound to be supplied to BioNumerik, subject
                  to meeting the competitive requirements of price, quality,
                  supply, delivery and other material terms relative to other
                  potential or active manufacturers. If such bid from Sumika is
                  on substantially competitive terms with BioNumerik's other
                  alternatives for manufacturing Compound, then BioNumerik and
                  Sumika will negotiate in good faith to enter into an amendment
                  to this Agreement providing for the manufacture by Sumika of a
                  significant portion of the Compound amounts required by
                  BioNumerik, which portion will be determined by BioNumerik in
                  its discretion based on BioNumerik's evaluation of
                  considerations including the need to manage risk by having
                  more than one manufacturer of Compound. In the event of any
                  unsuccessful bid by Sumika, BioNumerik will describe to Sumika
                  the categories in which its bid was deemed not competitive. In
                  the absence of any bid from Sumika (within 60 days of receipt
                  of the notice from BioNumerik) to manufacture Compound on
                  substantially competitive terms to BioNumerik's other bid,
                  BioNumerik shall be free to utilize such other alternatives
                  for the manufacture of manufacturing alternatives Compound.
                  Until an amendment to this Agreement is entered into by the
                  Parties, Sumika's obligations shall continue to manufacture
                  and supply Compound as provided in this Agreement. The Parties
                  recognize that Sumika shall have reasonable opportunities to
                  be a significant manufacturer of Compound as provided above,
                  but that no assurance can be given that Sumika will be a sole
                  source for the Compound due to the expected volume of use,
                  taxation/importation costs that may be encountered in various
                  territories, and other considerations.

2.4               BioNumerik and Sumika will regularly communicate concerning
                  the purchase and sale of the Compound. BioNumerik shall
                  provide to Sumika, no later than the 15th day following the
                  end of each Calendar Quarter, a forecast of its estimated
                  purchase orders from Sumika for the 12 calendar months
                  following the month in which the forecast is transmitted.
                  BioNumerik may make more frequent forecasts as it may deem
                  necessary. Except as otherwise provided herein, the terms and
                  conditions of all sales of the Compound by Sumika to
                  BioNumerik shall be in accordance with an acknowledgement
                  ("Acknowledgement") provided by Sumika to BioNumerik in
                  response to each purchase order placed by BioNumerik
                  hereunder. The quantity of each shipment of the Compound
                  specified in each Acknowledgement shall be definitive for all
                  purposes herein absent conclusive error. BioNumerik shall
                  provide Sumika with purchase order(s) for Compound at least
                  [**] prior to the time BioNumerik requires such Compound.
                  Each minimum purchase order amount of the Compound by
                  BioNumerik shall be [**]. During the term of this Agreement,
                  Sumika shall provide BioNumerik with such quantities of
                  Compound as may be requested by BioNumerik and accepted by
                  Sumika in accordance with the terms of this Agreement.




2.5               BioNumerik shall test and approve the quality of delivered
                  Compound within 21 days after receipt of the Compound. If
                  BioNumerik fails to so test or approve, BioNumerik shall be
                  deemed to have tested and approved the quality of such
                  Compound. If BioNumerik informs Sumika within the said 21
                  days' period that the delivered Compound does not meet the
                  Specifications, BioNumerik shall, within 10 days thereafter,
                  send back the non-conforming Compound, and disclose the test
                  results concerning such Compound, to Sumika. Then, the Parties
                  shall cooperate with each other in promptly examining such
                  test results and promptly comparing the non-conforming
                  Compound in question and the sample of the Compound retained
                  by Sumika. If the Compound proves to be non-conforming at the
                  time of delivery to BioNumerik, upon BioNumerik's written
                  request, Sumika will promptly send to BioNumerik without
                  additional charge replacement amounts of the ordered Compound
                  that were non-conforming, and provide BioNumerik with a credit
                  equal to the transportation costs of such non-conforming
                  Compound. Sumika's foregoing obligations shall be the sole
                  remedy to BioNumerik Sumika's total responsibility shall not

exceed the value of the Compound in question plus related shipping costs. Prior to approval of the Compound for commercial sale, BioNumerik shall warehouse any back-up supply of Compound purchased by BioNumerik from Sumika. If the Parties discuss and agree that Sumika will hold such inventory on behalf of BioNumerik, then Sumika shall send BioNumerik lot sample(s) of the Compound and then BioNumerik shall test and approve the quality of such sample(s) within 21 days of receipt thereof and shall thereafter make the payment for such Compound within 30 days; provided, however, that if the quality of the Compound has been approved in advance by BioNumerik, then BioNumerik shall make the payment within 30 days after BioNumerik's order therefor with Sumika. Such Compound shall be subject to the product warranties set forth in Article 4 of this Agreement.

2.6               The price of the Compound shall be on a [**] and in accordance
                  with Annex 2 attached hereto. In the event that BioNumerik
                  requests for the delivery of the Compound on other trade
                  terms, any increase of transportation and other costs incurred
                  by such request shall be borne by BioNumerik. Payment for all
                  Compound purchased from Sumika by BioNumerik in accordance
                  with this Agreement and approved by BioNumerik in accordance
                  with Section 2.5 shall be made in full within 30 days after
                  Compound satisfying the required Specifications are received.
                  BioNumerik shall make such payment without set-off,
                  counterclaim, or other such rights which BioNumerik may claim
                  against Sumika. Overdue payments shall accumulate interest
                  thereon at the rate of 14 percent per annum. Payment by
                  BioNumerik hereunder shall be made by wire transfer in
                  accordance with Annex 3.



2.7               As a part of this Agreement, Sumika shall maintain all of the
                  appropriate Specifications and standard operating procedures
                  related to the manufacturing of the Compound. These will be
                  treated as controlled documents and will be maintained
                  utilizing a suitable document control procedure to ensure
                  proper issuance and change, respectively. During the term of
                  this Agreement and for a period of at least two years
                  thereafter, Sumika shall maintain records of inspection and
                  testing, lab notebooks and procedures made in connection with
                  the manufacturing work conducted under this Agreement. In
                  addition, as a part of this Agreement Sumika shall prepare and
                  maintain an updated Drug Master FIle (DMF) for the Compound
                  for the United States, the European Union, and Japan and shall
                  answer any deficiency letter that the U.S. FDA and/or other
                  relevant regulatory health authority may issue to BioNumerik
                  regarding the manufacturing process for the Compound, provided
                  that the Parties shall discuss and agree in writing upon the

                           Party hereunder;

                           undertake the sole control of the defense of any such
                           action and claim, including all negotiations for the
                           settlement, or compromise of such claim or action at

10                TERM AND TERMINATION

10.1              This Agreement shall enter into force as of the Effective Date
                  of the Agreement and unless earlier terminated, shall continue
                  in full force and effect until BioNumerik's fulfilling and
                  completing its obligations set forth in Section 2.1 unless
                  extended by agreement of the Parties. Sections 4, 7, 8, 9, 11,
                  16 and 17 shall survive any termination of this Agreement.

10.2              The Parties may terminate this Agreement upon mutual written
                  agreement at any time during the Term of this Agreement.

10.3              Either party may terminate this Agreement without penalty at
                  any time without payment of any compensation by giving six
                  months prior written notice of termination to the other party,
                  if either party believes that such termination is reasonably
                  justified, provided that, if requested by the non-terminating
                  party, the terminating party shall discuss such termination
                  with the other party for a period of up to 60 days in a good
                  faith and best effort to find a mutually agreeable solution
                  for avoiding such termination. If the circumstances require
                  more than 60 days to adequately discuss such matter, the 60
                  days discussion period set forth in the preceding sentence
                  will be extended to up to 180 days (inclusive of the 60 day
                  discussion period described above) at the request of either
                  party. In the event that both parties fail to find a mutually
                  agreeable solution for avoiding such termination in such a
                  period of 60 days or 180 days as stipulated above, this
                  Agreement shall be terminated, provided however that ,
                  notwithstanding the provisions of Section 10.1, (i) any rights
                  and obligations of each party under this Agreement except
                  those stipulated in clauses (ii) and (iii) of this sentence
                  set forth below shall lose effect on the date of such
                  termination, (ii) the Parties shall be responsible for
                  fulfilling and completing all orders for Compound made by
                  BioNumerik prior to the date of such termination, and (iii)
                  Sections 4, 7, 8, 9, 11, 16, and 17 shall survive any such
                  termination.

10

11.1              In no event shall either Party be liable to the other Party or
                  third parties for any indirect, incidental or consequential
                  damages, such as e.g. lost profits in connection with its
                  performance under this Agreement or any breach thereof. The
                  restrictions of liability to compensate damages stipulated for
                  in this article shall not be applied to any breach of the
                  intellectual property rights of Sumika or BioNumerik or its
                  principals, including but not limited to rights of patent,

                  indirect, including but not limited to damages suffered due to
                  loss of profits, business or good-will, provided that the
                  amount of such compensation shall not exceed the value of the
                  Compound sold and purchased between the Parties under this
                  Agreement.

                  be deemed null and void.

(a) Termination. Terminate this Lease by giving written notice of termination to Tenant, in which event Tenant shall immediately surrender the Premises to Landlord. If Tenant fails to so surrender the Premises, then Landlord may, without, prejudice to any other remedy it has for possession of the Premises or arrearages in rent or other damages, re-enter and take possession of the Premises and expel or remove Tenant and any other person occupying the Premises or any part thereof, by any lawful means, without being liable for prosecution or claim for damages whether caused by the negligence of Landlord or otherwise.

(b) Continuation of Lease: Reletting of Premises. Landlord may continue this Lease in full force and effect, in which case Tenant is liable for all rents and other amounts payable under this Lease. Landlord may, nevertheless. re-enter and take possession of the Premises. by any lawful means, without terminating this Lease and without being liable for prosecution or for any claim for damages therefor. and relet the Premises and apply the rent received to the account of Tenant. No reletting by Landlord is considered to be for its own account unless Landlord has notified Tenant that this Lease has been terminated. Landlord may relet the Premises for a period or periods of time equal to, lesser or greater than the remainder of the Term, and on whatever terms and conditions Landlord, in its sole discretion. deems advisable. Landlord's action under this subsection (b) is not considered an acceptance of Tenant's surrender of the Premises unless Landlord expressly so notifies or agrees with Tenant in writing.

(c) Act for Tenant. Re-enter the Premises by any lawful means, without terminating this Lease and without being liable for any prosecution or for any claim for damages therefore, and do whatever Tenant is obligated to do under the terms of this Lease. Tenant shall pay to Landlord, on demand. expenses incurred by Landlord in effecting compliance with Tenant's obligations under this Lease, plus interest thereon at the lesser of 18% per annum or the highest lawful rate, from the date expended until repaid. Landlord is not liable for any damages resulting to Tenant from such action, whether caused by negligence of Landlord or otherwise.

(d) Change Locks. Landlord may change the locks on doors permitting entry into the Premises and deny Tenant's access thereto until all Events of Default have been cured. Landlord has no obligation to advise Tenant of the change of locks other than to provide written notice at Premises of the person whom Tenant may contact, during the normal business hours for the Premises of which Tenant has advised Landlord in writing, to acquire additional Information. Tenant waives all rights under Chapter 93 of the Texas Property Code to which it is otherwise entitled.

(e) Recapture of Advance Benefits. In addition to the remedies set forth in Sections 13.2(a)-(d), inclusive, on the occurrence of an Event of Default by Tenant under this Lease with respect to which Landlord elects either to terminate this Lease or, without terminating this Lease, to terminate Tenant's possession of the Premises. (i) Tenant shall pay to Landlord in cash on demand an amount equal to all "Reimbursable Costs" (as defined below) for which Tenant has not yet vested (as defined below). and (ii) any remaining rental abatement and/or other concessions that have not yet accrued under this Lease shall terminate. As used herein. the

21

term "Reimbursable Costs" means the total of (i) the aggregate dollar value of all rental abatements that Tenant has received under this Lease; and (iii) the aggregate dollar amount which has been paid to or on behalf of Tenant under this Lease, including. without limitation. any brokerage commission paid and/or payable by Landlord in connection with the execution of this Lease. Because the Reimbursable Costs were incurred by Landlord in reliance on Tenant's fully performing Tenant's obligations under this Lease. Tenant hereby acknowledges that Landlord will be damaged on a default by Tenant in an amount equal to the aggregate dollar value of the Reimbursable Costs for which Tenant has not yet vested. in addition to (and not 1n lieu of) any other damages suffered by Landlord. Tenant shall vest as to Reimbursable Costs at the rate of (A) 100% divided by the number of months in the initial Term for which Tenant is obligated to pay full rent, (B) multiplied by the number of months for which Tenant has paid full rent and is not otherwise in default hereunder. No vesting shall occur with respect to any month for which Tenant has not paid rent or in which Tenant is otherwise in default hereunder. For example, if Tenant is obligated to pay full rent for 50 months, then Tenant shall vest hereunder at the rate of 2% for each month for which it pays full rent.

(f) Lease Remedies Not Exclusive; Lease Supersedes Property Code. Pursuit of any of the foregoing remedies does not constitute an irrevocable election of remedies nor preclude pursuit of any other remedy provided elsewhere in this Lease or by applicable law, and none is exclusive of another unless so provided in this Lease or by applicable law. Likewise, forbearance by Landlord to enforce one or more of the remedies available to it on an Event of Default does not constitute a waiver of that default or of the right to exercise at remedy later or of any rent, damages or other amounts due to Landlord hereunder. In the case of a inflict. and to the extent that Chapter 93 of the Texas Property Code applies to this Lease, the terms of this Lease supersede and control the provisions of Chapter 93 of the Texas Property Code.

13.3 Tenant's Liability For Landlord's Damages.

(a) In General. In all events, Tenant is liable for all damages of whatever kind or nature, direct or indirect, suffered by Landlord as a result of the occurrence of an Event of Default.

(b) Termination of Lease. If Landlord terminates this Lease under Section 13.2(a). then Tenant shall pay to Landlord on demand the amount of all loss and damage suffered by Landlord by reason of the termination, to be determined by one or a combination of the following measures of damages:

22

(i) Until Landlord is able, through good faith efforts (the nature of which shall be at Landlord's sole discretion), to relet the Premises. Tenant shall pay to Landlord on or before the first day of each calendar month. the amounts required to be paid by Tenant under this Lease. After the Premises have been relet by Landlord, Tenant shall pay to Landlord on the 20th day of each calendar month, the difference between the amount required to be paid by Tenant under this Lease for that calendar month and the amount actually collected by Landlord for that month. If it becomes necessary for Landlord to bring suit to collect a Deficiency. Landlord may allow the deficiency to accumulate and may bring an action on several or all of the accrued deficiencies at one time. No suit shall prejudice to any way Landlord's right to bring a similar action for any deficiency or deficiencies that arise later. Any amount collected by Landlord from subsequent tenants for any calendar month which exceeds the amounts required to be paid by Tenant under this Lease shall be credited to reduce Tenant's liability for any calendar month for which the amount collected by Landlord is less than the amount required to be paid by Tenant, as Tenant's sole right to that excess.

(ii) When Landlord desires to do so. including after it has elected to proceed under subparagraph (i) immediately above (that election not being exclusive under this Lease). Landlord may demand a final settlement. On that demand, Landlord is entitled to receive from Tenant the difference between the total of all amounts required to be paid by Tenant under this Lease for the remainder of the Term minus the reasonable rental value of the Premises for that period, with such difference to be discounted to a present value based on a rate equal to the rate of interest allowed by law in Texas when the parties to a contract have not agreed on a particular rate of interest (or, in the absence of such a stipulated rate. at the rate of 10% per annum).

(iii) Landlord's election to proceed under subsection
(i) above shall not prejudice its right thereafter to cancel that election in favor of the remedy described in subsection (ii) above, so long as at the time of that cancellation, Tenant is still in default.

(c) Continuation of Lease: Reletting of Premises. If Landlord elects to continue this Lease in effect, then Tenant is liable for the rent and other amounts due hereunder. If Landlord relets the Premises for the account of Tenant, then the amounts actually received by Landlord shall be credited to the amounts owed by Tenant under this lease (including the amounts described in Section 17.3(a)).

Tenant shall pay to Landlord, upon demand, all fees of any consultants Landlord employees in connection with its review and approval of Tenant's Final Plans, not to exceed $1,000.00. If Tenant requests any change, addition or alteration (a "Change") to the Final Plans or in the construction of the Leasehold Improvements, Landlord shall either approve or disapprove in writing the proposed change within five (5) business days of Tenant's request.

Under no circumstances is Landlord's approval of Tenant's Plans to be considered approval of their correctness, of their compliance with applicable building and fire codes and all other requirements of any governmental authority having jurisdiction over the Premises, or of other sufficiency or adequacy for Tenant's purposes, and Tenant shall save and hold Landlord, its officers, employees, legal representatives and assigns harmless from all liability, claim, cost and expense incurred in connection with the failure of any Leasehold improvements constructed in accordance with the Final Plans to comply with said requirements and codes. The Leasehold Improvements constructed as a part of the Final Plans shall be the property of Landlord and shall remain upon and a part of and be surrendered with the Premises upon the expiration of the Term of the Lease.

2. Building Permit, Certificate of Occupancy. Tenant shall be responsible for obtaining all necessary building and other permits for construction of the Leasehold Improvements and for obtaining a certificate of occupancy permitting unconditional occupancy and use of the Premises (for the purpose stipulated in
Section 1.1(r)) after completion of the Leasehold Improvements.

3. Payment for Work. Landlord shall provide to Tenant an allowance not to exceed $15.00 per square foot of Rentable Area of the fourth (4th) floor portion of the Premises plus $2.50 per square foot of Rentable Area of the twelfth
(12th) floor of the Premises (the "Allowance") to be applied to pay only for those actual coats of the Leasehold improvements, including, without limitation, architectural and engineering fees relating to the construction of the Leasehold Improvements to the Premises. The Allowance shall be provided only upon receipt of paid invoices from Tenant.


In the event the cost of constructing the Leasehold Improvements to the Premises described on the Final Plans exceeds the Allowance (the "Excess") Tenant shall pay any such Excess. The Allowance for each floor shall be treated separately and in the event Tenant does not fully utilize all the Allowance on one particular floor, such remaining portion of the Allowance may not be applied to the other floor. Tenant shall promptly pay any such Excess and shall comply fully with any contract or other agreement therefor, to the end that there is no basis for a mechanic's or materialman's lien claim against the Premises or the Building.

If Tenant requests any changes in the Final Plans, then any of those changes that are approved by Landlord shall become part of the Final Plans, and the costs of revising the Final Plans and the costs resulting from the changes shall be added to the Excess, and shall be paid in accordance with the provisions set out in this Rider 301.

If the actual construction costs are less than the Allowance, Tenant shall not be entitled to any portion of the unexpended Allowance, which shall belong to Landlord.

4. Construction. Construction of the Leasehold Improvements shall be performed by Tenant's contractors. In selecting Tenant's contractor, Tenant must competitively bid the Final Plans to at least three (3) qualified contractors. A Qualified Contractor shall be defined as one which meets the insurance requirements and reasonable approvals of Landlord. Landlord shall apply the Allowance only to the amount stipulated in the lowest qualifying bid and no portion of the Allowance may be applied to pay any construction cost of any other Qualified Contractor which is in excess of the lowest bid, reasonable change order cost excepted.

5. Delay. Tenant shall pay any and all costs and expenses incurred by Landlord in connection with any delay in the commencement or completion of the Leasehold Improvements caused by (i) Tenant's failure to timely prepare and submit Tenant's Plans; (ii) Tenant's specification of non-building standard improvements or finishes; (iii) any change, additions or alteration to the Final Plans (or the Leasehold improvements covered thereby) that are requested by Tenant; and (iv) any other delay requested or caused by Tenant.

6. Commencement Date/"Ready for occupancy". For the purpose of this First Amendment to Lease, the Premises are "ready for occupancy" on the first to occur of (i) the date that the Leasehold Improvements to the Premises- described on the Final Plane are substantially completed except for any minor punch-list items to be performed by Tenant's contractor, or (ii) on the date on which Tenant begins occupancy of the Premises, or (iii) the date on which substantial completion would have occurred, but for delays of the nature described in Paragraph 5 of this Rider 301, but in no event later than six (6) months after the full execution of this Amendment. Once the Premises are deemed "ready for occupancy", Tenant shall sign a letter, in a form and fashion satisfactory to Landlord, acknowledging that the Premises have been completed in accordance with the Final Plans and stating the Commencement Date and expiration date of the Term of the Lease. However, Tenant's failure to execute or deliver such a letter shall not delay or otherwise change the Commencement Date.

7. Default. A default by Tenant under this Work Letter is an Event of Default under the Lease and entitles Landlord to any remedies under the Lease (notwithstanding that tile Term thereof has not commenced).

8. Indemnity. Tenant shall indemnify, defend, and hold Landlord harmless from and against any damages suffered by Landlord as a result of Tenant's failure to comply with the terms of this workletter.

9. Landlord Furnished Materials. In addition to the Allowance provided by Landlord above, Landlord shall make available to Tenant (for the construction of the initially leased Premises only) at no additional cost, "stockpiled materials" which may be currently stored in the vacant spaces of the Building. Any such materials not actually used in the construction of the Premises shall be returned to Landlord's inventory. Such inventory of remaining "stockpiled materials" is attached as Exhibit "H".

EXPANSION OPTION/RIGHT OF FIRST OFFER

1. "Expansion Option". So long as Tenant is in possession of the Premises and has not committed an Event of Default under this Lease and Tenant's financial condition, as determined by Landlord is comparable to Tenant's financial condition at the time of the full execution of this Amendment, during the first eighteen (18) months after the commencement Date referenced in Paragraph 4 of this Amendment, Tenant shall have the option (hereinafter defined as the "Expansion Option") to lease an additional 3,960 square feet of Rentable Area on the fourth (4th) floor of the Building where indicated on Exhibit "A-1" attached to be identified as part of Suite 400 (hereinafter defined as the "Expansion Space").

(a) To exercise the Expansion Option (i) Tenant must give written notice (hereinafter defined as the "Expansion Notice") of its intention to lease the Expansion Space at least sixty (60) days prior to the date Tenant anticipates occupying the Expansion Space, (ii) Tenant must lease the entire Expansion Space, and (iii) such anticipated occupancy date must not be later than eighteen
(18) months after the Commencement Date referenced in Paragraph 4 of this Amendment.

(b) Upon receipt of the Expansion Notice from Tenant, Landlord shall submit to Tenant an amendment within fifteen (15) business days setting forth the terms and conditions of such expansion. Such amendment shall establish the effective date of the changes to the Lease and shall set forth the increases in the Area of the Premises, Tenant's Pro Rata share and Tenant's Base Rental. In the event Tenant does not fully execute the amendment in a final form and fashion that is satisfactory to both parties, Landlord shall be free to market the Expansion Space unconditionally and this Expansion Option shall be of no further force or effect.

(c) Once the Expansion Space is "ready for occupancy" (as defined in Rider 301) Tenant's Base Rental for the entire Premises including the Expansion Space shall be increased to the amounts set forth in the following schedule:

                                  Monthly Base Rental for the entire
Monthly Period                 Premises (including the Expansion Space)
--------------                 ----------------------------------------
1-12                                         $16,332.63
13-24                                         17,022.93
25-36                                         17,824.98
37-48                                         18,540.98
49-60                                         19,254.65

For purposes of example only, in the event the Expansion Space is "ready for occupancy" on month five (5) of the Term of the Lease, Tenant's Base Rental as increased by the leasing of the Expansion Space would be $16,332.63 and continue in accordance with the remainder of the schedule above.

(d) In the event Tenant exercises this Expansion Option and the Expansion Space is not "ready for occupancy" within eighteen (18) months after the Commencement Date referenced in Paragraph 4 of this Amendment for any reason whatsoever, Tenant's Base Rental as increased by the leasing of the Expansion Space


shall nevertheless become due and payable on the nineteenth (19th) month of the Term of the Lease in accordance with the amounts set forth in the above schedule.

(e) Leasehold Improvements to the Expansion Space shall be constructed in accordance with Rider 301 attached hereto, provided, however, anything contained in Rider 301 to the contrary notwithstanding the following shall apply:

(i) Tenant shall submit its plans and specifications (for the Expansion Space) referenced in Paragraph 1(a) of said rider to Landlord for approval no later than ten (10) days after Landlord and Tenant fully execute an amendment to the Lease as referenced above; and

(ii) the Allowance for the Expansion space shall not exceed $59,400.00 and such Allowance shall be proportionately reduced by the ratio which the remaining Term of the Lease bears to the Term as stipulated in Paragraph 5 of this Amendment.

(f) As consideration for Landlord providing Tenant this Expansion Option right, until such time as the Expansion Option expires or Tenant has elected to exercise the Expansion Option and has subsequently begun paying the increased Base Rental in accordance with the schedule of Base Rental set forth in 1(c) above, Tenant shall pay as additional Base Rental, the amounts set forth in the following schedule:

                           Additional Base Rental for Tenant's
Monthly Period                   Expansion Option Rights
--------------                   -----------------------
1-6                                     $    0.00
7-12                                     1,524.60
13-18                                    1,980.00

2. "Right of First Offer". Provided there has not been an occurrence of an Event of Default by Tenant and Tenant is in possession of the Premises, Tenant shall have the right to lease the balance of the fourth (4th) floor and all of the sixth (6th) and the seventh (7th) floors should they become available for lease to a third party tenant during tile Term of the Lease (hereinafter defined as the "Right of First Offer"). Landlord shall notify Tenant in writing of the availability of such space and the terms and conditions under which Tenant shall be able to lease such space prior to marketing said space to a third party. Upon such notice Tenant shall have twenty (20) days to either lease such space on the terms and conditions that Landlord has presented to Tenant or counter Landlord with terms and conditions acceptable to Tenant and Landlord. In the event Landlord and Tenant agree to such expansion Landlord and Tenant shall execute an amendment to this Lease in a form and fashion satisfactory to both parties, setting forth the terms and conditions of such expansion. In the event Tenant does not respond or an agreement is not reached within ten (10) days of Landlord's receipt of any counter offer from Tenant, Landlord shall be free to market such space unconditionally.

OPTION TO EXTEND

Tenant shall have one (1) option (the "Option") to renew and extend the Term of this Lease for sixty (60) months (the "Renewal Term"), which option shall follow consecutively on the expiration of the Term of this Lease, provided that at the time that the option to renew is exercised, this Lease is in full force and effect, Tenant is not in default hereunder and has not vacated the Premises. The option shall be exercised by Tenant's giving to Landlord written notice of its intention to renew and extend the Term of this Lease at least twelve (12) months and no more than fifteen (15) months before the expiration date of the initial Term of this Lease. The renewal and extension of this Lease for the Renewal Term shall be on and under the same covenants, agreement, terms, provisions, and conditions as are contained herein for the initial Term of this Lease, including those providing for adjustments to the rent; provided however, that the rent for the Renewal Terms shall be at the then prevailing rental rate for comparable office space. In determining the then prevailing rental rate, Landlord will take into consideration Tenant's creditworthiness, recent leases in the Building and in comparable office buildings in a comparable geographic area, provided however, in the determination of the then prevailing rental rate any recent leases containing previously negotiated rental discounts (i.e. renewal rate ceilings established at the time of initial lease execution, etc.) shall be excluded. A legal document satisfactory to both parties shall be executed by both parties that reflects the terms and conditions of such Renewal Term. Any assignment or subletting by Tenant in violation or breach of Section 11.1 of this Lease or vacating the Premises, shall terminate the Option to Tenant set forth herein. Any termination of this Lease during the initial Term shall terminate all rights of renewal and extension set forth in this Rider 301. In the event Tenant elects to lease less Rentable Area than the initially leased Premises, this option to renew will become null and void.

At any time during the forty-five (45) day period immediately preceding the date by which Tenant is required to exercise a renewal option, Tenant may request in writing a quote from Landlord of the rent that will be applicable for the Renewal Term. Landlord shall respond to a timely written request by providing Tenant a written quote of the rent within fifteen (15) business days after Landlord's receipt of Tenant's request.

3. Section 1.1 (m) "Term" shall commence May 1, 1992 and end April 30, 2002.

4. If the Expansion Option is exercised before December 31, 1995 the Base Rental Rates for Suite 400 described above shall also apply to the Expansion Space as defined in the Expansion Option contained in Rider 401 attached to the First Amendment. Such Expansion Option shall be extended and remain available to Tenant through December 31, 1995, provided, however, if Tenant has not exercised said Expansion Option by July 1, 1995, Tenant shall commence paying a Retention Fee in the amount of $1,524.00 per month to retain such Expansion Option rights through December 31, 1995. Should Tenant fail to timely remit such Retention Fee, Tenant shall forfeit Tenant's rights under the Expansion Option. The Retention Fee provides Tenant no additional rights other than to exercise the rights set forth in Rider 401 and to require Landlord not enter into a lease with another party for the Expansion Space prior to December 31, 1995. This provision supercedes the payment schedule set forth in Paragraph 1 (f) of Rider 401 to the Lease.

Paragraph 1 (c) of Rider 401 shall be deleted in its entirety and the schedule of Base Rental amounts set forth in Paragraph 1 of this Amendment shall be increased in accordance with the following schedule once the Expansion Space is "ready for occupancy" (as defined in Rider 301):

                                                  MONTHLY BASE RENTAL FOR
   MONTHLY PERIOD                                  THE EXPANSION SPACE*

7-1-94 thru 6-30-95                                     $3,960.00
7-1-95 thru 6-30-96                                     $4,118.40
7-1-96 thru 6-30-97                                     $4,316.40
7-1-97 thru 6-30-98                                     $4,483.51
7-1-98 thru 6-30-99                                     $4,649.83
7-1-99 thru 6-30-00                                     $4,973.76
7-1-00 thru 6-30-01                                     $5,294.52
7-1-01 thru 4-30-02                                     $5,635.08

*This amount shall be added to Total Monthly Base Rental shown in Paragraph 1 of this Amendment upon exercise of the Expansion Option.

5. Should Tenant exercise its Right of First Offer as described in Paragraph 2 of Rider 401 before March 31, 1995, then the Base Rental Rates for Suite 400 shall apply to the areas covered by the Right of First Offer of the 4th floor. Failure to exercise this Right of First Offer prior to March 31, 1995 shall relieve Landlord of any obligation to offer the predetermined Base Rental Rate but shall not cause the Right of First Offer to terminate in regards to the remaining 4th, 6th and 7th floor space. Additionally, Landlord and Tenant do hereby agree that in regard to the remaining 4th floor space, Tenant is hereby notified said space is available for lease to Tenant. Except as limited above to defined rental rates, Tenant may lease said area under the same conditions as the Expansion Space and in accordance with the notice provisions contained in Rider 401.

6. Tenant may elect to terminate this Lease as of June 30, 1999, provided however, Tenant has provided Landlord a minimum of six (6) months prior written notice and a maximum of twelve (12) months prior written notice of its intention to exercise said option. To exercise said option Tenant shall remit to Landlord at that time, along with said notice, a Termination Fee payable to Landlord in the amount of $46,855.80. Notwithstanding such option, Tenant shall remain obligated to pay for any sums which it is liable under the Lease including, but not limited to, any and all of its Prorata Share of Operating


Costs which may not have matured as of the effective date of termination plus any remaining unpaid sums (i.e. separate utility charges, past due rentals, late fees, etc.). All such sums remaining due from Tenant shall be payable within thirty (30) days of receipt of Landlord's invoice therefore. In the event the Premises is expanded during the initial term of the Lease and Tenant exercises this option to terminate in accordance with the terms stipulated above, Tenant shall remit an Additional Termination Fee. Such Additional Termination Fee shall be based on the following formula:

                            34
Total Expenses    X   --------------------     =     Additional
                      Remaining Lease Term           Termination Fee

Total Expenses are defined as those expenses incurred by Landlord in connection with the leasing of any such expanded area(s) to include, but not be limited to, architectural fees, consulting fees, finish allowances, etc., but not to include leasing commissions. Remaining Lease Term is defined as the months and days remaining in the term of the Lease at the time such expanded area is "ready for occupancy" through April 30, 2002.

7. The following provision "Supplemental Chiller" is hereby added to the Lease: In the interest of Landlord and Tenant, Landlord has installed a supplemental chilled water system (the "Supplemental Chiller") to provide supplemental cooling to the Building and Tenant's 4th floor Premises. Tenant shall be provided use of the Supplemental Chiller in a quantity not to exceed eighty (80) tons of its one hundred and forty (140) ton capacity (equal to 192 gallons per minute). Tenant shall be responsible for all costs of accessing the chilled water supplied by the Supplemental Chiller to the fourth floor in the location identified by Landlord. In consideration of Landlord's installation of the above system Tenant agreed to pay, and has paid to Landlord eighty thousand three hundred and eighty eight no/100 dollars ($80,388.00).

All utility costs, routine maintenance and repairs and all other costs associated with the use of the Supplemental Chiller shall be borne by Landlord and Tenant on a prorata basis based upon the actual ratio of BTU's consumed by each party. To measure Tenant's use, a BTU metering device shall be installed by Tenant, at Tenant's sole cost and expense, in the 4th floor janitor's closet near the point of supply of the chilled water to the 4th floor Premises. To measure Landlord's use (which for the proposes hereunder shall include other tenant's usage but shall not include Tenant's usage), a BTU metering device(s) shall be installed by Landlord so that any and all such usage of the Supplemental Chiller can be accurately measured. Such metering device(s) shall, at a minimum, measure the temperature differential between the supply and return chilled water lines and record the flow rate of chilled water in gallons per minute (GPM) serving the Premises and other areas served by the Supplemental Chiller, process this data and display the total heat used in BTU's.

Utility costs for this service shall be based on the then applicable rate assessed by the local utility company, City Public Service, or its successor, for such service actually used by Tenant and paid for by Landlord. Such cost shall be calculated based on 1 kilowatt hour per 3413 BTU's of consumption.

8. Paragraph B Option to Terminate as contained in the Addendum to this Lease is hereby deleted in its entirety and Tenant shall have no rights to terminate or cancel this Lease, except as otherwise provided in the Lease or subsequent amendments.

9. The parties hereto do hereby agree that the previous Second Amendment to Lease dated the 28th day of February, 1994 was never fully executed or accepted by either party and shall be considered null and void and shall not be legally binding on either party to this Lease.

10. Notwithstanding anything contained in Paragraph 15 of the First Amendment to Lease, the Letter of Credit shall be provided for the period starting July 1, 1994 and ending June 30, 1999.


11. Section 22.18 "Guarantee" is hereby amended so that Tenant's delivery of said irrevocable Letter of Credit shall be due within one (1) week of full execution of this Amendment. The monthly periods referenced in Paragraph 15 of the First Amendment to Lease shall be deemed to have commenced July 1, 1994, and as such the amount of said Letter of Credit initially provided to Landlord may be reduced in accordance with the provisions contained in Section
22.18. Tenant hereby acknowledges and agrees that Landlord shall have no responsibility to disburse any portion of the Allowance referenced in Rider 301 of the Lease until such time as Landlord has received said Letter of Credit in a form that is reasonably acceptable to Landlord. Tenant shall be solely responsible for any late fees, charges or expenses incurred in the discharging of any mechanics liens on the property or Building occasioned or caused by any potential payment delays resulting from Landlord's withholding of the Allowance or otherwise.

BioNumerik Pharmaceuticals, Inc., a Delaware Corporation hereby affirms the terms of the Lease, the First Amendment and this Second Amendment, Exhibits and Riders, and further attorns to, assumes and agree to be bound by all the terms of the Lease. This Second Amendment to Lease supercedes the Lease and First Amendment to Lease and if there shall be a conflict or an inconsistency between any of these agreements, the Second Amendment to Lease shall govern and control. Except as specifically amended herein, the Lease dated May 1, 1992, (all its Exhibits and Riders) by and between Landlord and Tenant, shall remain in full force and effect in accordance with its terms and provisions.

IN WITNESS WHEREOF, the parties herein have hereunto set forth their hands this 28th day of February, 1995.

NOW THEREFORE, in consideration of the Leased Premises and the mutual benefits to accrue to Landlord and Tenant, both parties agree that the above described Lease, as amended by the First Amendment and the Second Amendment, shall be further amended as follows:

1. Term Extension

The Lease Term shall be extended for a total of forty-four (44) months ("Extension Term") from the current expiration date of April 30, 2002 to a new expiration date of December 31, 2005.

2. Expansion Option

Tenant shall have the option to lease the balance of the space on the fourth floor of the Building ("Expansion Option") as shown on the attached floor plan ("Expansion Space") by providing Landlord written notice on or before December 31, 1998.

The Expansion Space shall be deemed to contain 8,001 rentable sq. ft. If the Expansion Option is exercised, the Leased Premises when combined with the Expansion Space, shall contain 21,033 rentable sq. ft.

Landlord will provide the Expansion Space in an "as is" condition and: a) allow Tenant access to and use of any building materials stored therein; b) provide a base buildout allowance of $15.00 per rentable sq. ft. or $120,015.00; c) provide an architectural and engineering allowance of $.50/rentable sq. ft. or $4000.50; and d) provide, at Tenant's option, an additional buildout allowance of $6.00 per rentable sq. ft. or $48,006.00 to be amortized monthly over the term of the Lease at 10% interest (collectively, the "Buildout Allowances"). Tenant shall have the right to construct improvements in the Expansion Space without paying a construction management fee to Landlord or Landlord's agent, subject only to Landlord's approval of the Expansion Space construction documents, as such approval is described in Rider 301 of the First Amendment to Lease ("Workletter").

Tenant shall pay a Base Rental for the Expansion Space as follows:

    TERM                    MONTHLY RATE                ANNUAL RATE
    ----                    ------------                -----------
7/99 - 12/03                  $ 1.5416                    $ 18.60
1/04 - 12/04                    1.6333                      19.60

Whether or not Tenant has completed the buildout of the Expansion Space, the Base Rental shall commence one hundred eighty (180) days after delivery of Tenant's written notice to exercise the Expansion Option but in no event later than July 1, 1999. The lease term on the Expansion Space shall expire on December 31, 2005.

For purposes of calculating Tenant's Pro Rata Share of Operating Costs attributable to the Expansion Space, the actual Operating Costs for calendar year 1999 shall be Landlord's Operating Cost contribution. Tenant's Pro Rata Share attributable to the Expansion Space is 4.193% and if this Expansion Option is exercised, 11.02% for the combined Leased Premises.

Tenant will be provided a total of twenty-four (24) additional parking spaces. These additional parking spaces will be at no charge for the term of the Lease, and will be unreserved and will be provided as eighteen (18) covered and six (6) open spaces.


3. Termination Option

Upon execution of this Amendment, Tenant will be deemed to have canceled its existing Termination Option as described in item number 6 in the Second Amendment. Tenant may elect to terminate the Lease, as amended ("Termination Option") as of December 31, 2002 by providing Landlord a minimum of six (6) months prior written notice to exercise this Termination Option. If the Expansion Option has been exercised, Tenant shall remit to Landlord a payment ("Termination Fee") equal to the unamortized Buildout Allowance on the Expansion Space only, as calculated on a straight line basis over the total potential term (i.e., until December 31, 2005). If the Termination Option is allowed to expire and is not exercised, Landlord agrees to pay Cross & Company or its successors or assigns, a cash, lump sum leasing commission equal to four percent (4%) of the gross rent to be paid by Tenant on the Leased Premises over the remaining uncancelable term no later than thirty (30) days after June 30, 2002.

4. Tenant or Tenant's officers shall not be required to provide a Letter of Credit or Guarantee as described in the Lease Agreement, First or Second Amendment.

5. Tenant's Right of First Offer to Lease any and all space as it becomes available on the sixth and seventh floor of the Property, as contained in section 2 of Rider 401 of the First Amendment to Lease shall continue in full force and effect. Should Tenant not exercise the Expansion Option, the Tenant shall have a Right of First Refusal on the balance of the fourth floor. Landlord shall provide written notification of the bona fide intent of a third party tenant to lease any or all of this fourth floor space and the terms and conditions which the third party tenant is willing to accept. Tenant shall then have ten (10) business days in which to either accept this space on the same terms and conditions as the third party or to allow Landlord to enter into a lease with the third party. Should the Landlord and the third party fail to execute a lease or should the space again become available for lease during Tenant's term, this Right of First Refusal will still be valid and applicable to this space.

6. Tenant shall have the right to lease any or all of the shell space on the fourth floor of the building at a monthly rate of 54.167(cent) per square foot for storage. This space shall be used solely for the purposes of storing Tenant's equipment, furniture and files only, and for no other purpose. This agreement, as it applies to this storage space only, may be terminated by either party providing fifteen (15) day written notice to the other party.

Except as described in this Amendment, the terms of which shall control if in conflict with the Lease or the First or Second Amendment to Lease, all other terms and conditions of the Lease, First or Second Amendments to Lease shall remain in full force and effect. Except as otherwise defined herein, all capitalized terms used but not defined herein shall have the same meanings assigned to such terms in the Lease, as amended by the First and Second Amendment.

AGREED AND ACCEPTED this 28th day of October , 1998.

NOW THEREFORE, in consideration of the Leased Premises and the mutual benefits to accrue to Landlord and Tenant, both parties agree that the above described Lease, as amended by the First, Second and Third Amendments, shall be further amended as follows:

1. Lease Space Expansion

The Leased Premises shall be expanded by 8,001 rentable square feet or from 13,032 rentable square feet prior to the execution of this Fourth Amendment to a new total of 21,033 rentable square feet. The 8,001 rentable square feet represents the balance of the fourth floor of the Building, as shown on the attached floor plan, and shall be known as the Second Expansion Space ("Second Expansion Space").

2. Expansion Space Tenant Finish

Landlord shall provide an allowance of $15.00 per rentable square foot or a total of $120,015 towards Tenant's interior finish in the Second Expansion Space.

Base rental for the Third Expansion Space shall commence as stipulated on the above schedule regardless of the completeness of any leasehold improvements to be constructed by Tenant.

4. Other

a. For purposes of calculation of Tenant's Pro Rata Share of Operating Costs attributable to the Third Expansion Space, the actual Operating Costs for calendar year 2001 shall be Landlord's Operating Cost contribution. Tenant's Pro Rata Share is 4.991% for the Third Expansion Space and 16.013% for the combined leased premises.

b. The lease term on the Third Expansion Space shall expire on December 31, 2005, except as hereafter provided. Tenant shall have the right to terminate the Lease, as amended, ("Third Expansion Space Termination Option") for the area contained in the Third Expansion Space as of December 31, 2003. To exercise this Termination Option, Tenant must provide Landlord a minimum of six (6) months prior written notice. The Termination Option, as described in the Third Amendment to Lease, Section #3 and the Second Expansion Space Termination Option, as described in the Fourth Amendment, Section 4.b are hereby amended so as to be exercisable and effective in the same manner and as of the same date (as of 12/31/03) as this Third

2

Expansion Space Termination Option; provided however, the parties hereto agree that in the event Tenant elects to exercise the foregoing termination options, the aggregate termination fee shall be $86,814.90. If such termination option is allowed to expire and is not exercised, Landlord agrees to pay Cross & Company or its successors or assigns, a cash, lump sum leasing commission equal to four percent (4%) of the Total Base Rental to be paid by Tenant on the Leased Premises over the remaining uncancelable term. This commission shall be paid no later than January 31, 2004.

c. Landlord shall provide Tenant a total of twenty-nine (29) additional parking spaces at no charge for the term of the Lease to be taken as twenty one (21) in-garage spaces and eight (8) surface spaces resulting in an aggregate of sixty-nine (69) total parking spaces, fifty (50) in garage spaces and nineteen (19) surface spaces.

d. Landlord recognizes and accepts that Tenant has entered into a short term space sublease with the existing tenant in the Third Expansion Space, subject to Landlord's approval of the sublease document. Said sublease shall expire on June 30,2001.

e. Section 11.2 of the Lease is deleted in its entirety and replaced with the following: "Notwithstanding anything to the contrary in this Lease, Tenant may, without obtaining Landlord's prior written consent, sublet the Premises or assign the Lease to (a) an entity controlled by or under common control with Tenant, (b) a successor entity related to Tenant by merger, consolidation, non-bankruptcy reorganization, or governmental action, or (c) a purchaser of substantially all of Tenant's assets located in the Premises (a "Permitted Transfer"). A sale or transfer of Tenant's capital stock, including pursuant to an initial public offering, shall not be deemed an assignment, subletting or any other transfer of the Lease or Premises. No such Permitted Transfer shall be subject to any rights of recapture or rent profit-sharing provisions."

f. Section 22.16 is hereby modified by the addition of the following sentence to the end of the paragraph:
"Notwithstanding the foregoing, Tenant may disclose, without prior written consent of the Landlord, the terms and provisions of this Lease as required by law, including as part of any initial public offering of Tenant's stock."

g. Landlord consents to the Changes in Ownership.

h. This Agreement, together with the Lease, as amended, constitutes the entire agreement between Landlord and Tenant regarding the Lease and the subject matter contained herein and supersedes any and all prior and/or contemporaneous oral or written negotiations, agreements or understandings. This Fifth Amendment shall be binding upon and inure to the benefit of Landlord and Tenant and their respective heirs, legal representatives, successors and assigns. No subsequent change or addition to this Fifth Amendment shall be binding unless in writing and duly executed by both Landlord and Tenant. Except as specifically amended hereby, all of the terms and conditions of the Lease, as amended, are and shall remain in full force and effect and are hereby ratified and confirmed. This Fifth Amendment may be executed in two or more counterparts, each of which shall constitute an original, but all of which, taken together, shall constitute but one Agreement. An executed facsimile copy of this Fifth Amendment shall be considered an original.

Except as described in this Fifth Amendment, the terms of which shall control if in conflict with the Lease or the First, Second, Third or Fourth Amendments to the Lease, all other terms and conditions of the Lease, as amended by the First, Second, Third and Fourth Amendments to the Lease shall remain in full force and effect. Except as otherwise defined herein, all capitalized terms used but not defined herein shall have the same meanings assigned to such terms in the Lease, as amended by the First, Second, Third and Fourth Amendments.

EXHIBIT 10.10

BIONUMERIK PHARMACEUTICALS, INC.

1995 DIRECTOR STOCK OPTION PLAN

1. Purposes of the Plan. The purposes of this Director Stock Option Plan are to attract and retain the best available personnel for service as Directors of the Company, to provide additional incentive to the Outside Directors of the Company to serve as Directors, and to encourage their continued service on the Board.

All options granted hereunder shall be "non-statutory stock options".

2. Definitions. As used herein, the following definitions shall apply:

(a) "Board" shall mean the Board of Directors of the Company.

(b) "Common Stock" shall mean the Common Stock of the Company.

(c) "Company" shall mean BIONUMERIK PHARMACEUTICALS, INC., a Texas corporation.

(d) "Continuous Status as a Director" shall mean the absence of any interruption or termination of status as a Director.

(e) "Director" shall mean a member of the Board.

(f) "Employee" shall mean any person, including officers and Directors, employed by the Company or any Parent or Subsidiary of the Company. The payment of a director's fee by the Company shall not be sufficient in and of itself to constitute "employment" by the Company.

(g) "Exchange Act" shall mean the Securities Exchange Act of 1934, as amended.

(h) "Option" shall mean a stock option granted pursuant to the Plan.

(i) "Optioned Stock" shall mean the Common Stock subject to an Option.

(j) "Optionee" shall mean an Outside Director who receives an Option.

(k) "Outside Director" shall mean a Director who is not an Employee.


(l) "Parent" shall mean a "parent corporation", whether now or hereafter existing, as defined in Section 425(e) of the Internal Revenue Code of 1986, as amended.

(m) "Plan" shall mean this 1995 Director Stock Option Plan, as amended.

(n) "Share" shall mean a share of the Common Stock, as adjusted in accordance with Section 11 of the Plan.

(o) "Subsidiary" shall mean a "subsidiary corporation", whether now or hereafter existing, as defined in
Section 425(f) of the Internal Revenue Code of 1986, as amended.

3. Stock Subject to the Plan. Subject to the provisions of Section 11 of the Plan, the maximum aggregate number of Shares which may be optioned and sold under the Plan is 300,000 Shares (the "Pool") of Common Stock. The Shares may be authorized, but unissued, or reacquired Common Stock.

If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares which were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan.

4. Administration of and Grants of Options under the Plan.

(a) Administrator. Except as otherwise required herein, the Plan shall be administered by the Board.

(b) Procedure for Grants. All grants of Options hereunder shall be made strictly in accordance with the following provisions:

(i) No person shall have any discretion to select which Outside Directors shall be granted Options.

(ii) Each Outside Director shall be automatically granted an Option (the "First Option") to purchase the First Option Amount (as described in Section 4(b)(vi) below) upon the later to occur of (A) the effective date of this Plan, as determined in accordance with Section 6 hereof, or (B) the date on which such person first becomes a Director, whether through election by the shareholders of the Company or appointment by the Board of Directors to fill a vacancy.

(iii) After a First Option has been granted to any Outside Director, each Outside Director shall thereafter be automatically granted an Option (a "Subsequent Option") to purchase the Subsequent Option Amount (as described in Section 4(b)(vii) below) on the day of each subsequent annual shareholders meeting at which such Outside Director is reelected to an additional term; provided, however, that for the first annual shareholders meeting following the date on which such person first becomes a Director (the "First Subsequent Meeting Date"), such

2

Outside Director shall be granted an Option to purchase a number of Shares which is equal to the Subsequent Option Amount for other Directors at such First Subsequent Meeting Date multiplied by that fraction of a year (which fraction shall not exceed one) that has elapsed from the date such person first became a Director to such First Subsequent Meeting Date.

(iv) Notwithstanding the provisions of subsections
(ii) and (iii) hereof, in the event that a grant would cause the number of Shares subject to outstanding Options plus the number of Shares previously purchased upon exercise of Options to exceed the Pool, then each such automatic grant shall be for that number of Shares determined by dividing the total number of Shares remaining available for grant by the number of Outside Directors on the automatic grant date. Any further grants shall then be deferred until such time, if any, as additional Shares become available for grant under the Plan through action to increase the number of Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder.

(v) The terms of an Option granted hereunder shall be consistent with the requirements set forth elsewhere in this plan and shall additionally include the following:

(A) The Option shall be exercisable only while the Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof.

(B) With respect to grants occurring prior to June 1, 1999, the Option shall become exercisable in installments cumulatively with respect to 1/36 of the Shares covered thereby for each complete calendar month after the date of grant of such Option provided, however, that in no event shall any Option be exercisable prior to obtaining shareholder approval of the Plan in accordance with Section 17 hereof. With respect to grants occurring after June 1, 1999, the Option shall become exercisable in installments cumulatively with respect to 1/12 of the Shares covered thereby for each complete calendar month after the date of grant of such Option.

(C) Notwithstanding any other provisions hereof, the grant of initial Options to the Outside Directors of the Company holding office on the date the Plan is adopted by the Board shall be subject to shareholder approval of the Plan in accordance with Section 17(a) hereof and, subject to such approval, the monthly vesting of such initial Options shall commence as of the effective date of the Plan.

(vi) With respect to grants occurring prior to June 1, 1999, the "First Option Amount" shall be an Option to purchase 7,500 Shares. With respect to grants occurring after June 1, 1999, the "First Option Amount" shall be an Option to purchase the Industry Report Amount as determined in accordance with Section 4(b)(vii) below.

(vii) With respect to grants occurring prior to June 1, 1999, the "Subsequent Option Amount" shall be an Option to purchase 2,500 Shares. With respect to grants occurring after June 1, 1999, the "Subsequent Option Amount" shall be an Option to purchase that number of Shares (the "Industry Report Amount") that is determined by the Board in good faith to correspond to the size of option grant awards made to outside directors upon

3

reelection to the board as published in current and representative report(s) (collectively, the "Industry Report") of industry specific compensation amounts determined in good faith by the Board to be representative benchmarks of outside director compensation for companies in the life science industry. Option award amounts in the Industry Report based on a standardized number of outstanding shares shall be proportionately adjusted to reflect the actual number of outstanding shares of Company stock at the time of the grant.

(c) Powers of the Board. Subject to the provisions and restrictions of the Plan, the Board shall have the authority, in its discretion:
(i) to determine, upon review of relevant information and in accordance with
Section 8(b) of the Plan, the fair market value of the Common Stock; (ii) to determine the exercise price per share of Options to be granted, which exercise price shall be determined in accordance with Section 8(a) of the Plan; (iii) to interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations relating to the Plan; (v) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted hereunder; and (vi) to make all other determinations (including the determinations provided in Section 4(b) hereof) deemed necessary or advisable for the administration of the Plan.

(d) Effect of Board's Decision. All decisions, determinations and interpretations of the Board shall be final and binding on all Optionees and any other holders of any Options granted under the Plan.

(e) Suspension or Termination of Option. If the Chief Executive Officer or his designee reasonably believes that an Optionee has committed an act of misconduct, the Chief Executive Officer may suspend the Optionee's right to exercise any option pending a determination by the Board of Directors (excluding the Outside Director accused of such misconduct). If the Board of Directors (excluding the Outside Director accused of such misconduct) determines an Optionee has committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation owed to the Company, breach of fiduciary duty or deliberate disregard of the Company rules resulting in loss, damage or injury to the Company, or if an Optionee makes an unauthorized disclosure of any Company trade secret or confidential information, engages in any conduct constituting unfair competition, induces any Company customer to breach a contract with the Company or induces any principal for whom the Company acts as agent to terminate such agency relationship, neither the Optionee nor his estate shall be entitled to exercise any option whatsoever. In making such determination, the Board of Directors (excluding the Outside Director accused of such misconduct) shall act fairly and shall give the Optionee an opportunity to appear and present evidence on Optionee's behalf at a hearing before a committee of the Board.

5. Eligibility. Options may be granted only to Outside Directors. All Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) hereof. An Outside Director who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options in accordance with such provisions.

The Plan shall not confer upon any Optionee any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in

4

any way with any rights which the Director or the Company may have to terminate his directorship at any time.

6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board of Directors of the Company or its approval by the shareholders of the Company as described in Section 17 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 13 of the Plan.

7. Term of Option. The term of each Option shall be ten (10) years from the date of grant thereof.

8. Exercise Price and Consideration.

(a) Exercise Price. The exercise price per Share of the First Options to be granted to the Outside Directors of the Company holding office on the date of adoption of the Plan by the Board shall be $4.10 per Share. Thereafter, the per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be 100% of the fair market value per Share on the date of grant of the Option.

(b) Fair Market Value. The fair market value shall be determined by the Board in its discretion; provided, however, that where there is a public market for the Common Stock, the fair market value per Share shall be the mean of the bid and asked prices of the Common Stock in the over-the counter market on the date of grant, as reported in The Wall Street Journal (or, if not so reported, as otherwise reported by the National Association of Securities Dealers Automated Quotation ("NASDAQ") System) or, in the event the Common Stock is traded on the NASDAQ National Market System or listed on a stock exchange, the fair market value per Share shall be the closing price on such system or exchange on the date of grant of the Option, as reported in The Wall Street Journal.

(c) Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option shall consist entirely of cash, check, other Shares of Common Stock of the Company which (i) either have been owned by the Optionee for more than six (6) months on the date of surrender, or were not acquired directly or indirectly from the Company, and
(ii) have a fair market value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment.

9. Exercise of Option.

(a) Procedure for Exercise: Rights as a Shareholder. Any Option granted hereunder shall be exercisable at such times as are set forth in
Section 4 hereof; provided, however, that no Options shall be exercisable until shareholder approval of the Plan in accordance with Section 17 hereof has been obtained.

An Option may not be exercised for a fraction of a Share.

5

An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 8(c) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. A share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Status as a Director. In the event of the termination of the Outside Director's Continuous Status as a Director, he may, but only within thirty (30) days after the date of such termination, exercise his Option to the extent that he was entitled to exercise it at the date of such termination. To the extent that he was not entitled to exercise an Option at the date of such termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, the Option shall terminate.

(c) Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's Continuous Status as a Director as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Internal Revenue Code of 1986, as amended), he may, but only within six (6) months (or such other period of time not exceeding twelve (12) months as is determined by the Board) from the date of such termination (but in no event later than the date of expiration of the term of such Option as set forth in the Option Agreement), exercise his Option to the extent he was entitled to exercise it at the date of such termination. To the extent that he was not entitled to exercise the Option at the date of termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, the Option shall terminate.

(d) Death of Optionee. In the event of the death of an Optionee:

(i) during the term of the Option who is at the time of his death a Director of the Company and who shall have been in Continuous Status as a Director since the date of grant of the Option, the Option may be exercised, at any time within twelve (12) months following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of death.

(ii) within thirty (30) days after the termination of Continuous Status as a Director, the Option may be exercised, at any time within twelve (12) months following the

6

date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of termination.

10. Non-Transferability of Options. Unless determined otherwise by the Board, an Option may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution or pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder. The designation of a beneficiary by an Optionee does not constitute a transfer. Unless determined otherwise by the Board, an Option may be exercised, during the lifetime of the Optionee, only by the Optionee or a transferee permitted by this Section 10. If the Board makes an Option transferable, such Option shall contain such additional terms and conditions as the Board deems appropriate.

11. Adjustments Upon Changes in Capitalization or Merger. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without payment or receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.

In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option will terminate immediately prior to the consummation of such proposed action. In the event of a merger of the Company with or into another corporation in which the stock of the Company is exchanged for stock of another company, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Board determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Optionee shall have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. If the Board makes an Option fully exercisable in lieu of assumption or substitution in the event of a merger, the Board shall notify the Optionee that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option will terminate upon the expiration of such period.

7

12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date determined in accordance with Section 4(b) hereof. Notice of the determination shall be given to each Outside Director to whom an Option is so granted within a reasonable time after the date of such grant.

13. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act (or any other applicable law or regulation, including the requirements of the NASD or an established stock exchange), the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. Notwithstanding the foregoing, the provisions set forth in
Section 4(b) of this Plan (and any other Sections of this Plan that affect the formula award terms required to be specified in this Plan by Rule 16b-3) shall not be amended more than once every six months, other than to comport with change in the Code, the Employee Retirement Income Security Act, or the rules thereunder.

(b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company.

14. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

8

15. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

16. Option Agreement. Options shall be evidenced by written option agreements in such form as the Board shall approve.

17. Shareholder Approval.

(a) Continuance of the Plan shall be subject to approval by the shareholders of the Company at or prior to the first annual meeting of shareholders held subsequent to the adoption of the Plan by the Board of Directors of the Company. If such shareholder approval is obtained at a duly held shareholders' meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company present or represented and entitled to vote thereon. If such shareholder approval is obtained by written consent, it may be obtained by the written consent of the holders of a majority of the outstanding shares of the Company.

(b) At such time as the Company is subject to Section 14(a) of the Exchange Act, any required approval of the shareholders of the Company shall be solicited substantially in accordance with the applicable provisions of
Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder.

18. Information to Optionees. The Company shall provide to each Optionee, during the period for which such Optionee has one or more Options outstanding, copies of all annual reports to shareholders, proxy statements and other information provided to all shareholders of the Company.

4. Administration of the Plan.

(a) Procedure.

(i) Administration With Respect to Directors and Officers. With respect to grants of Options to Employees who are also officers or directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board to administer the Plan, which Committee shall be constituted in such a manner as to permit the Plan to comply with Rule 16b-3 promulgated under the Exchange Act or any successor thereto ("Rule 16b-3") with respect to a plan intended to qualify thereunder as a discretionary plan. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies, however caused, and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by Rule 16b-3 with respect to a plan intended to qualify thereunder as a discretionary plan. Notwithstanding the foregoing, the Plan shall not be administered by the Board if (a) the Company and its officers and directors are then subject to the requirements of Section 16 of the Exchange Act and (b) the Board's administration of the Plan would prevent the Plan from complying with Rule 16b-3.

(ii) Multiple Administrative Bodies. If permitted by Rule 16b-3, the Plan may be administered by different bodies with respect to directors, nondirector officers and Employees who are neither directors nor officers.

(iii) Administration With Respect to Consultants and Other Employees. With respect to grants of Options to Employees or Consultants who are neither directors nor officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the legal requirements relating to the

3

administration of incentive stock option plans, if any, of corporate and securities laws applicable to the Company and of the Code (the "Applicable Laws"). Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies, however caused, and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan and in the case of a Committee, the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion:

(i) to determine the Fair Market Value of the Stock, in accordance with Section 2(j) of the Plan;

(ii) to select the officers, Consultants and Employees to whom Options may from time to time be granted hereunder;

(iii) to determine whether and to what extent Options are granted hereunder;

(iv) to determine the number of shares of Stock to be covered by each such award granted hereunder;

(v) to approve forms of agreement for use under the Plan;

(vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder (including, but not limited to, the per share exercise price for the Shares to be issued pursuant to the exercise of an Option and any restriction or limitation, or any vesting acceleration or waiver of forfeiture restrictions regarding any Option or other award and/or the shares of Stock relating thereto, based in each case on such factors as the Administrator shall determine, in its sole discretion);

(vii) to determine whether and under what circumstances an Option may be bought-out for cash under subsection 9(f);

(viii) to determine whether, to what extent and under what circumstances Stock and other amounts payable with respect to an award under this Plan shall be deferred either automatically or at the election of the participant (including providing for and determining the amount during any deferral period); and

4

(ix) to reduce the exercise price of any Option to the then current Fair Market Value if the Fair Market Value of the Stock covered by such Option shall have declined since the date the Option was granted.

(c) Effect of Committee's Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees and any other holders of any Options. Neither the Committee nor any member thereof shall be liable for any act, omission, interpretation, construction or determination made in connection with the Plan in good faith, and the members of the Committee shall be entitled to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including counsel fees) arising therefrom to the full extent permitted by law.

5. Eligibility.

(a) Nonqualified Stock Options may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or Consultant who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options.

(b) Each Option shall be designated in the written option agreement as either an Incentive Stock Option or a Nonqualified Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of the Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonqualified Stock Options.

(c) For purposes of Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted.

(d) The Plan shall not confer upon any Optionee any right with respect to continuation of employment or consulting relationship with the Company, nor shall it interfere in any way with his right or the Company's right to terminate his employment or consulting relationship at any time, with or without cause, unless otherwise agreed in writing by the Company and such Optionee.

6. Term of Plan. The Plan shall become effective upon its adoption by the Board of Directors. It shall continue in effect until September 10, 2003 unless extended by the Board or sooner terminated under Section 14 of the Plan. No grants of Options will be made pursuant to the Plan after September 10, 2003.

5

7. Term of Option. The term of each Option shall be the term stated in the Option Agreement; provided, however, that in the case of an Incentive Stock Option, the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. However, in the case of an Incentive Stock Option granted to an Optionee who, at the time the Option is granted, owns Stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement.

8. Option Exercise Price and Consideration.

(a) The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the following:

In the case of an Incentive Stock Option

(i) granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant.

(ii) granted to any Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant.

(b) The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist entirely of (1) cash, (2) check, (3) promissory note, (4) other shares of the Company's capital stock which (x) in the case of shares of the Company's capital stock acquired upon exercise of an Option either have been owned by the Optionee for more than six months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, (5) authorization from the Company to retain from the total number of Shares as to which the Option is exercised that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for the total number of Shares as to which the Option is exercised, (6) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price, (7) by delivering an irrevocable subscription agreement for the Shares which irrevocably obligates the option holder to take and pay for the Shares not more than twelve months after the date of delivery of the subscription agreement, (8) any combination of the foregoing methods of payment, (9) or such other

6

consideration and method of payment for the issuance of Shares to the extent permitted under applicable laws.

9. Exercise of Option.

(a) Procedure for Exercise: Rights as a Stockholder. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed to be exercised, and the Optionee deemed to be a stockholder of the Shares being purchased upon exercise, when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 8(b) of the Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Employment. In the event of termination of an Optionee's relationship as a Consultant (unless such termination is for purposes of becoming an Employee of the Company) or Continuous Status as an Employee with the Company (as the case may be), such Optionee may, but only within ninety (90) days (or such other period of time as is determined by the Board, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option and not exceeding ninety (90) days) after the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise his Option to the extent that Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of such termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate.

(c) Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's relationship as a Consultant or Continuous Status as an Employee as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months from the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise the Option to the extent otherwise entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate.

7

(d) Death of Optionee. In the event of the death of an Optionee, the Option may be exercised, at any time within twelve (12) months following the date of death (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent the Optionee was entitled to exercise the Option at the date of death. To the extent that Optionee was not entitled to exercise the Option at the date of death, or if the Optionee's estate (or such other person who acquired the right to exercise the Option) does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate.

(e) Rule 16b-3. Options granted to persons subject to Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

(f) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

10. Non-Transferability of Options. Unless determined otherwise by the Administrator, an Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. If the Administrator makes an Option transferable, such Option shall contain such additional terms and conditions as the Administrator deems appropriate.

11. Stock Withholding to Satisfy Withholding Tax Obligations. At the discretion of the Administrator, Optionees may satisfy withholding obligations as provided in this paragraph. When an Optionee incurs tax liability in connection with an Option, which tax liability is subject to tax withholding under applicable tax laws, and the Optionee is obligated to pay the Company an amount required to be withheld under applicable tax laws, the Optionee may satisfy the withholding tax obligation by electing to have the Company withhold from the Shares to be issued upon exercise of the Option, that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the "Tax Date").

All elections by an Optionee to have Shares withheld for this purpose shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions:

(a) the election must be made on or prior to the applicable Tax Date;

(b) once made, the election shall be irrevocable as to the particular Shares of the Option or Right as to which the election is made;

8

(c) all elections shall be subject to the consent or disapproval of the Administrator; and

(d) if the Optionee is subject to Rule 16b-3, the election must comply with the applicable provisions of Rule 16b-3 and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

In the event the election to have Shares withheld is made by an Optionee and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Optionee shall receive the full number of Shares with respect to which the Option is exercised but such Optionee shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date.

12. Adjustments Upon Changes in Capitalization, Merger or Change in Control.

(a) Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option, and the number of Shares which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Stock (or Common Stock into which the Common Stock may be convertible) resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Stock, or any other increase or decrease in the number of issued shares of Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Stock subject to an Option.

(b) In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option will terminate immediately prior to the consummation of such proposed action. In the event of a merger or consolidation of the Company with or into another entity or another transaction pursuant to which all or substantially all of the assets of the Company are conveyed to another entity, the Option shall be assumed or an equivalent option shall be substituted by such successor entity or a parent or subsidiary of such successor entity. In the event that such successor entity does not agree to assume the Option or to substitute an equivalent option, the Administrator shall, in lieu of such assumption or substitution, provide for the Optionee to have the right to exercise the Option as to all of the Optioned Stock,

9

including Shares as to which the Option would not otherwise be exercisable. If the Administrator makes an Option fully exercisable in lieu of assumption or substitution in the event of a merger, consolidation or other transaction covered by this paragraph, the Administrator shall notify the Optionee that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option will terminate upon the expiration of such period.

(c) If the employment of any Optionee that is an Employee is terminated by the Company other than for Cause (as defined in subsection (d) below) within one year following a change in control (as defined below), then all outstanding Options held by such Optionee on the date of such termination shall automatically become 100% vested and fully exercisable. For this purpose, a "change in control" means the occurrence of any of the following after April 14, 1998:

(i) The acquisition by any person of direct or indirect beneficial ownership of the Company's outstanding voting securities in an amount sufficient to elect a majority of the Company's Board of Directors. For purposes of this subsection (c), the term "person" means any group, corporation, partnership, association, trust (other than any trust holding stock for the account of Employees of the Company pursuant to any stock purchase, ownership or employee benefit plan of the Company), business entity, estate, or natural person, and "beneficial ownership" means the direct or indirect power to vote or to direct the voting of the security or the direct or indirect power to dispose or direct the disposition of the security.

(ii) Completion of a tender offer or exchange offer for and acquisition of 50% or more of the voting securities of the Company that is required to be reported by the offeror to the Securities and Exchange Commission pursuant to Section 14(d) of the Exchange Act and the regulations promulgated thereunder.

(iii) The merger or consolidation of the Company with or into another entity in a transaction in which the shareholders of the Company immediately prior to such transaction do not own more than 50% of the voting securities of the surviving entity immediately following such transaction.

(iv) The sale or transfer of all or substantially all of the assets of the Company, other than to a wholly-owned subsidiary of the Company.

(d) For purposes of subsection (c) above, "Cause" shall be deemed to exist if:

(i) Optionee (A) has intentionally failed or refused or habitually has neglected to carry out or to perform the reasonable duties required of Optionee as an employee of the Company, after written notice from the Company of such failure, refusal, neglect or breach and the expiration of ten (10) business days following the delivery of such notice during which such failure, refusal, neglect or breach has remained unremedied, or (B) has intentionally breached any statutory or common law duty of loyalty to the Company;

10

(ii) Optionee has been indicted on felony charges or convicted of fraud, embezzlement or any crime involving moral turpitude, unless the Board determines in good faith that such indictment or conviction is unlikely to have a material adverse effect on the Company's business or reputation;

(iii) Optionee dies or becomes subject to a mental or physical condition that the Company, acting in good faith and upon reasonable grounds, determines will render Optionee unable to perform the essential functions of the job for which Optionee is employed (whether with or without reasonable accommodation on the part of the Company); or

(iv) Optionee materially breaches any confidentiality or noncompetition agreement between Optionee and the Company.

13. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Administrator makes the determination granting such Option, or such other date as is determined by the Administrator. Notice of the determination shall be given to each Employee or Consultant to whom an Option is so granted within a reasonable time after the date of such grant.

14. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act or with
Section 422 of the Code (or any other applicable law or regulation, including the applicable requirements of the NASD or an established stock exchange), the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required.

(b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company.

15. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

11

As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

16. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17. Agreements. Options shall be evidenced by written agreements in such form as the applicable Administrator shall approve from time to time.

18. Information to Optionees. The Company shall provide to each Optionee, during the period for which such Optionee has one or more Options outstanding, copies of all annual reports and other information which are generally provided to all stockholders of the Company. The Company shall not be required to provide such information to persons whose duties in connection with the Company assure their access to equivalent information.

19. Governing Law: Construction. All rights and obligations under the Plan shall be governed by, and the Plan shall be construed in accordance with, the laws of the State of Texas without regard to the principles of conflicts of laws. Titles and headings to Sections herein are for purposes of reference only, and shall in no way limit, define or otherwise affect the meaning or interpretation of any provisions of the Plan.

Dr. Baylin and Dr. Hausheer shall work together to develop and agree upon a definitive outline of the work to be conducted during the first year of the Program. Thereafter, the Program will be conducted pursuant to a definitive annual research plan to be agreed upon by the Institution and BioNumerik at least 30 days before the commencement of each future year of the Program.

It is intended that the Program research will include the following:

i) BioNumerik will endeavor to identify and synthesize molecules, which may be patentable or unpatentable, for the purpose of identifying and meeting molecular requirements for drug modulation of DNA methylation events.


ii) Dr. Baylin and the Institution will focus laboratory efforts and Dr. Baylin's personal expertise on the elucidation and clarification of key mechanism(s) for optimal therapeutic targeting in cancer cells which involve aberrant DNA methylation.

iii) BioNumerik will work to develop and refine robust and detailed atomistic and chemical structural models and perform physics-based computer simulations that describe the biological, thermodynamic, structural and biochemical mechanisms that are the focus of the laboratory work of the Institution under the Program and to use these models and information in the design and synthesis of its new chemical entities as described above.

iv) The Institution will conduct in vitro testing of the new compounds discovered and synthesized by BioNumerik for their ability to influence aberrant DNA methylation with a view to identifying the most potent and desirable potential therapeutic entity to advance to clinical trials in humans.

4. ADDITIONAL BIONUMERIK RESPONSIBILITIES.

(a) The work to be conducted by the Institution under this Agreement will be funded out of the [**] amounts paid by BioNumerik to Institution pursuant to the Joint Collaboration, Licensing, and Clinical Trials Agreement, dated as of February 9, 2000, between BioNumerik and The Johns Hopkins University.

(b) BioNumerik will also undertake sole responsibility for endeavoring to obtain patent protection (including payment of future patent filing fees) on new chemical entities which are developed under the Program and which are identified as either joint inventions or sole inventions of BioNumerik, in the United States and such other countries in the remainder of the world as BioNumerik may determine. The Institution will cooperate with BioNumerik in providing such information and assistance, and executing such documents and instruments, as may be requested by BioNumerik from time to time in connection with prosecution of patents relating to the joint Inventions (as hereinafter defined).

Company shall include in any agreement with its AFFILIATED COMPANIES or its SUBLICENSEE which permits such party to make, use or sell the LICENSED PRODUCT or provide LICENSED SERVICE, a provision requiring such party to retain records of sales of LICENSED PRODUCT and records of LICENSED SERVICE and other information as required in Paragraph 5.1 and permit JHU to inspect such records as required by this Paragraph.

5.3 REASONABLE EFFORTS. Within six months of each amendment of this License Agreement to include JHU inventions or discoveries made under the RESEARCH AGREEMENT, Company shall submit a Development Plan, reasonably satisfactory to JHU, which outlines Company's intent and ability to develop and commercialize the JHU inventions or discoveries. Company shall exercise reasonable efforts, consistent with the Development Plan provided, as might be amended from time to time, to develop and to introduce the LICENSED PRODUCT and LICENSED SERVICE into the commercial market as soon as practicable, consistent with sound and reasonable business practice and judgement; thereafter, until the expiration of the Agreement, Company shall endeavor to keep LICENSED PRODUCT and LICENSED SERVICE reasonably available to the public. Company shall also exercise commercially reasonable efforts to develop other LICENSED PRODUCT suitable for different indications, so that the PATENT RIGHTS can be commercialized as broadly and as speedily as good scientific and business judgement would deem practical.

5.4 OTHER PRODUCTS. After clinical or other evidence, provided in writing by JHU or by another party, to Company, demonstrating the practicality of a particular market which is not being developed or commercialized by Company, Company shall either provide JHU with a reasonable development plan and start development or attempt to reasonably sublicense the particular technology to a third party. If within twelve (12) months of such notification by JHU, Company has not initiated such development efforts or sublicensed that particular market, JHU may terminate this license for such particular therapeutic market. This Paragraph shall not be applicable if Company reasonably demonstrates to JHU that commercializing such LICENSED PRODUCT or LICENSED SERVICE or granting such a sublicense in said market would have a potentially adverse commercial effect upon marketing or sales of the LICENSED PRODUCT developed and being sold by Company.

5.5 PATENT ACKNOWLEDGEMENT. Company agrees that all packaging containing individual LICENSED PRODUCT sold by Company, AFFILIATED COMPANIES and SUBLICENSEE of Company will be marked with the number of the applicable patent(s) licensed hereunder in accordance with each country's patent laws.


5.6 JHU, through its JHU Inventor(s), shall within thirty days of the EFFECTIVE DATE ship Deliverables by overnight courier service to arrive at COMPANY on a business day.

THE JOHNS HOPKINS UNIVERSITY

BIONUMERIK PHARMACEUTICALS, INC.

JOINT COLLABORATION, LICENSING, AND CLINICAL TRIALS AGREEMENT

THIS AGREEMENT is made as of February 9, 2000 (the "Effective Date") by and between The Johns Hopkins University, organized and existing under the laws of the State of Maryland with its principal place of business at 720 Rutland Avenue, Baltimore, Maryland 21205 (the "University") and BioNumerik Pharmaceuticals, Inc., a Texas corporation with its principal place of business at Suite 1250, 8122 Datapoint Drive, San Antonio, Texas 78229 (the "Company").

RECITALS

WHEREAS the Company wishes to obtain the opportunity to discuss new technical developments with a view to potential licenses of certain inventions discovered and/or developed at the Johns Hopkins University Oncology Center (the "Center");

WHEREAS the Center believes that the Company is skillful in the commercialization of pharmaceutical compounds and seeks to benefit economically from the Company's efforts;

WHEREAS the Center desires to do clinical trials for the Company on an agreed basis respecting overhead costs;

WHEREAS in consideration of such basis, the Company is willing to give the Center certain first option rights on any clinical trials to be done by the Company; and

WHEREAS in consideration for these collaborations, the Company will pay to the Center [**] with the execution and delivery of this Agreement and an additional [**] on each of the next [**] anniversaries thereof.

NOW, THEREFORE, the Parties agree as follows:

PART I

TECHNICAL COLLABORATION

1.1 General. This Agreement anticipates a five-year collaboration between the University and the Company (the "Collaboration") providing for the further development by the Company of compounds invented by members of the faculty of the Center (collectively, the "Center Faculty") for the treatment of solid tumors and hematologic malignancies and the potential applications of such compounds ("Oncology Drugs").

[**] CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.


1.2 Term. The Collaboration will take place during the period commencing on the Effective Date and continuing for five years thereafter. The term of the Collaboration may be extended by written agreement between the parties.

1.3 Company's Option.

(a) The University hereby grants to the Company a first option to a worldwide, royalty bearing, exclusive license to inventions of the Center Faculty which are made in the course of performing research funded by this Agreement, subject to the rights of any additional sponsors including U.S. Government rights under 35 U.S.C. Sections 200-212. Inventions discovered through research funded by the Company are hereinafter referred to as "University Inventions".

(b) The University hereby grants to the Company a first option to a worldwide, royalty bearing, exclusive license to selected Oncology Drugs invented by Center Faculty without the Company's financial support and which are unencumbered by the licensing rights of commercial third parties. Inventions discovered without the Company's financial support are hereinafter referred to as "Selected Inventions."

(c) The Company shall have sixty (60) days from the date of receipt of an Invention Notice (defined in Section 1.6) to request that the parties enter license negotiations. In the event that the Company and the University determine to enter into a license negotiation with respect to a University Invention or Selected Invention, the University and the Company will begin such negotiations using the general license form attached hereto as Exhibit A but further negotiation between the parties will be unrestricted. The Office of Technology Licensing of the University's School of Medicine will represent the University in such negotiations.

1.4 Ownership of Collaboration Results. All inventions and discoveries shall be owned by the party making the invention or discovery. Any inventions deemed to be jointly made by the Company and the University shall be owned jointly by the Company and the University and subject to their respective license. Record title to patents and patent applications for University Inventions and/or Selected Inventions shall be held by the University. Record title to patents and patent applications for inventions made jointly by the University and the Company shall be joint and subject to their respective license.

1.5 Other Collaborations. Each of the University and the Company shall be free to conduct other research, whether under the sponsorship of or in collaboration with, the federal government or other third parties, or otherwise, provided that the terms and conditions of any such research, sponsorships, or collaborations shall not conflict with the terms of this Agreement.


1.6 Notice. The Center Faculty will promptly notify the Office of Technology Licensing of the University's School of Medicine (the "Licensing Office") in writing of any University Invention or Selected Invention (the "Invention Notice"). The Invention Notice will include a detailed written description of such invention. When a University Invention is not encumbered by the licensing rights of commercial third parties, the Licensing Office shall notify the director of the Center, who will promptly submit the Invention Notice to the Company. In the case of a Selected Invention, the Licensing Office and the director of the Center will review the Selected Invention and jointly determine whether the Company is a logical licensee, who is as capable of developing and commercializing the Selected Invention as other potential licensees. If the Licensing Office and the director of the Center agree that the Company is the logical licensee, the director of the Center will promptly submit the Invention Notice to the Company.

1.7 Educational Advancement. The University does not guarantee that any patentable or non-patentable Oncology Drugs will result from the Collaboration. The Company understands that the University's primary mission is educational and that the Collaboration is intended to forward that mission.

1.8 Consultation. The Company will make available its chief-executive officer, Frederick H. Hausheer, M.D. ("Dr. Hausheer"), to confer on-site with the Center one day per year, the Center Faculty, and the Center's investigators and researchers concerning Oncology Drugs developed by the Center Faculty. Dr. Hausheer's consultations will be without charge to the University.

1.9 Confidentiality. During the period this agreement is in effect and for a period of three (3) years thereafter, the University and the Company agree to keep in confidence and to use solely as contemplated in this agreement all information received from the other party under this agreement or obtained pursuant to or in connection with the Collaboration. All reasonable efforts will be used to avoid disclosure to any third party of any information supplied or developed under this agreement, unless the prior written consent of the other party is obtained. The preceding confidentiality requirements will not extend to any information which (a) is or becomes public knowledge, after the time it becomes public; (b) the receiving party can show by written or other tangible evidence was in its possession at the time of disclosure hereunder and which the receiving party without breach of any obligation is free to disclose to others;
(c) was received by the receiving party from a third party who did not acquire it, directly or indirectly, from the disclosing party under any obligation of confidentiality and which the third party is free to disclose to others; (d) is required to be disclosed by a court of law or by the regulations of a federal agency, subject to the earliest practical notification by the party obligated to make such disclosure so as to enable the other party to obtain such protective orders as may be available; or (e) is independently developed by the receiving party and which the receiving party can show by written or other tangible evidence was so independently developed.


1.10 Publication. Notwithstanding the foregoing, and except for information supplied by the Company and not otherwise known to the University, the University may publish in scientific journals research results arising from activities funded by the Company, from University Inventions, and from Selected Inventions for which the Company is given notice pursuant to Section 1.6, in accordance with the following procedures:

(a) the University will submit the proposed manuscript to the Company at least thirty (30) days prior to submission for publication; and

(b) within thirty (30) days of the receipt of such manuscript, the Company will advise the University whether the Company has determined that the manuscript contains patentable subject matter relating to a University Invention and whether the Company wishes that a patent application be filed.

If the Company notifies the University that the manuscript includes no confidential information and/or that the Company does not wish patent action to be taken, or if the Company does not so notify the University within the thirty
(30) day period, the University will be free to publish. If the Company wishes patent action to be taken, it will notify the University of its decision and patent protection will be sought pursuant to Section 1. 111. Neither the University nor any of its employees will submit the manuscript for publication or disclose its contents to third parties until patent applications have been filed. The patent application(s) will be filed within ninety (90) days of the University's receipt of the Company's notice requesting that the University seek patent protection. After the earlier of ninety (90) days or the filing of a patent application, the University will be free to submit and publish the manuscript. However, no publication of any compounds, structures or other information which is confidential information of BioNumerik will be made by the University without the prior written consent of the Company, which consent will not be unreasonably withheld.

1.11 Patents. Except as provided in Section 1.10, the Company may for a period of sixty (60) days after the Company's receipt of the Invention Notice elect to seek patent protection for any University Invention or Selected Invention with respect to which it negotiates a license. In the event the Company determines to seek patent protection, the Company will inform the University in writing of its election. The University will then cause to be prepared, filed, prosecuted, and maintained at the Company's expense patent applications and/or patents resulting therefrom, provided, however, that in the event that the Company and the University are unable to negotiate a license for such invention, the Company's liability for any additional patent expenses shall cease upon the University's receipt of the Company's written notification that it no longer wishes to continue negotiations, and the University will, upon licensing the invention to a commercial third party, reimburse the Company for all patent expenses which the Company incurred. Such patent preparation, filing, prosecution, and maintenance will be performed through outside patent counsel selected by the University and approved by the Company, which approval will not be unreasonably withheld. In the event the Company determines not to seek patent protection as provided herein, the University will be free to seek such protection at the University's expense.
