ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

DIRECTORS AND SENIOR MANAGEMENT

In accordance with the German Stock Corporation Act (Aktiengesetz), Bayer AG has both a Board of Management (Vorstand) and a Supervisory Board (Aufsichtsrat). The Board of Management is responsible for the management of our business; the Supervisory Board appoints and supervises the members of the Board of Management. The two boards are separate, and no individual may simultaneously be a member of both boards.

Members of both the Board of Management and the Supervisory Board owe a duty of loyalty and care to Bayer AG. In exercising their duties, the applicable standard of care is that of a diligent and prudent businessperson. Members of both boards must take into account a broad range of considerations when making decisions, including the interests of Bayer AG and its shareholders as well as of employees and creditors.

The members of the Board of Management and the Supervisory Board may be held personally liable to Bayer AG for breaches of their duties of loyalty and care. Bayer AG must bring an action for breach of duty against the Board of Management or Supervisory Board upon a resolution of the shareholders' meeting passed by a simple majority of votes cast, or upon the request of shareholders holding, as a group, at least 10 percent of the outstanding share capital. With the exception of shareholders of companies that (unlike Bayer AG) are under the control of another company, individual shareholders of German companies cannot sue directors on behalf of the company in a manner analogous to a shareholder's derivative action under U.S. law. Under German law, directors may be liable for breach of duty to shareholders (as opposed to a duty to the company itself) only where a breach of duty to the company also constitutes a breach of a statutory provision enacted specifically for the protection of shareholders. As a practical matter, shareholders are able to assert liability against directors for breaches of this sort only in unusual circumstances.

BOARD OF MANAGEMENT

The Board of Management is responsible for managing the business of Bayer AG in accordance with the German Stock Corporation Act and Bayer AG's Articles of Association. It also represents Bayer AG in its dealings with third parties and in court. According to the Articles of Association the Board of Management consists of a minimum of two members. The Supervisory Board determines the number of and appoints the members of the Board of Management. Members of the Board of Management are appointed by the Supervisory Board for a maximum term of five years and are eligible for reappointment after the completion of their term in office.

Bayer AG is legally represented by two members of the Board of Management acting together, or by one member of the Board of Management together with a person possessing a special power of attorney (Prokura).

The Board of Management must report regularly to the Supervisory Board, particularly on proposed business policy and strategy, profitability and on the current business of Bayer AG, as well as on any exceptional matters which may arise from time to time. If not otherwise required by law, the Board of Management decides with a simple majority of the votes cast. In case of deadlock, the vote of the chairman is the relevant vote.

Under certain circumstances, such as a serious breach of duty or a vote of no confidence by the shareholders in an annual meeting, a member of the Board of Management may be removed by the Supervisory Board prior to the expiration of his term. A member of the Board of Management may not deal with, or vote on, matters relating to proposals, arrangements or contracts between him/herself and Bayer.

Committees of the Board of Management oversee various aspects of the management of Bayer as a whole, with the committee chairmen holding primary responsibility. Individual Board members serve as representatives with primary responsibility for our various business segments and as representatives for the various geographic regions in which we operate.

Werner Wenning became chairman of our Board of Management in April 2002. He has served on the Board since 1997. Prior to becoming chairman, he served as chief financial officer and was a member of the Corporate Coordination and Human Resources Committees. From 1996 until he joined the Board in 1997, Mr. Wenning was head of Corporate Planning and Controlling. In addition to his responsibilities on the Board, he is a member of the supervisory boards of Dresdner Bank Lateinamerika AG, Gerling-Konzern Versicherungs-Beteiligungs AG and Rheinhyp Rheinische Hypothekenbank AG. Until May 2001, he served as a member of the supervisory board of Gerling-Konzern Allgemeine Versicherungs-AG. He is also the vice president of the Deutsches Aktieninstitut e.V. and a member of the Presidium of the Cologne Chamber of Industry and Commerce.

Dr. Attila Molnar has served on the Board of Management since 1999. Currently, he chairs the Human Resources Committee and is a member of the Technology and Environment Committee. He is the representative of the Board of Management responsible for the North America and Mexico regions. Dr. Molnar also represents the Agriculture businesses. Prior to joining the Board, Dr. Molnar was the general manager of Bayer's former Organic Chemicals business group from 1996 to 1999 and became the general manager of the Basic and Fine Chemicals business group in 1999, before joining the Board of Management later that year. We expect Dr. Molnar to leave the Board of Management in July 2002 in order to become president of Bayer Corporation, our U.S. subsidiary, as well as Senior Bayer Executive with responsibility for the United States.

Dr. Frank Morich has been a member of the Board of Management since 2000. He is chairman of the Research and Development Committee and a member of the Marketing and Logistics and the Technology and Environment Committees. He represents the Health Care businesses on the Board. Dr. Morich served as head of product development for our Pharmaceuticals segment from 1995 to February 1998 and then, until he joined the Board, as head of our Consumer Care business group. We expect Dr. Morich to leave the Board of Management in July 2002 in order to become chairman of the board of Bayer HealthCare AG, the new subsidiary that we plan to incorporate to operate our Pharmaceuticals, Consumer Care, Diagnostics, Biological Products and Animal Health businesses.

Dr. Udo Oels joined the Board of Management in 1996 and currently chairs the Technology and Environment Committee. He is also a member of the Research and Development and the Corporate Coordination Committees. He is the representative for the China region.

Werner Spinner has been a member of the Board of Management since 1998. He currently chairs the Marketing and Logistics Committee and is a member of the Finance Committee. He also represents the Polymers businesses as well as the Far East region. Prior to joining the Board, Mr. Spinner was the general manager of the Consumer Care business group from 1994 to 1998.

Klaus Kuhn is Bayer's chief financial officer. Prior to joining the Board in May 2002, Mr. Kuhn was head of Bayer's Finance Division. Prior to that appointment, he oversaw the spin-off of Bayer's former Agfa division. Before joining Bayer in 1998, Mr. Kuhn worked with Schering AG, most recently as head of finance. Mr. Kuhn is also a member of the board of directors of Agfa-Gevaert N.V.

Dr. Richard Pott joined the Board in May 2002. He had previously served as General Manager of our Specialty Products business group. Before assuming responsibility for Specialty Products, he served Bayer in a

82

number of positions, most recently as head of the Strategic Planning Department and then as head of Corporate Planning and Controlling. Dr. Pott is slated to oversee strategy and human resources when Bayer makes the transition to its planned holding company structure.

SUPERVISORY BOARD

Under the German Stock Corporation law, the German Co-Determination Act (Mitbestimmungsgesetz) of 1976 and our Articles of Association, the Supervisory Board consists of 20 members. The principal function of the Supervisory Board is to appoint and supervise the Board of Management. The Supervisory Board may not make management decisions, but the Board of Management's standard operating procedures (Geschaftsordnung) may require the prior consent of the Supervisory Board for specified transactions, including:

- the acquisition or disposition of investments above a specified threshold;

- the acquisition, disposition or encumbrance of real property;

- the creation of new business units or the disposition of existing units;

- the issuance of bonds, entering into of credit agreements, or grant of guaranties, sureties (Burgschaften) and loans, except to subsidiaries; and

- the establishment of branch offices (Zweigniederlassungen).

Our shareholders elect 10 members of the Supervisory Board at the annual meeting of shareholders. Pursuant to the Co-Determination Act of 1976, our employees elect the remaining 10 members. The term of a Supervisory Board member expires at the end of the annual meeting of shareholders in which the shareholders discharge Supervisory Board members for the fourth fiscal year following the year in which the member was elected. There is no compulsory retirement age for members of the Supervisory Board.

Any member elected by the shareholders in the annual meeting of shareholders may be removed by a majority of three quarters of the votes cast by the shareholders in such meeting. Any member elected by the employees may be removed by a majority of three quarters of the votes cast by the relevant class of employees. Unless not required by law or by the Articles of Association of Bayer AG, resolutions of the Supervisory Board are passed by simple majority of the votes cast. According to the Articles of Association, in the case of a deadlock, a second vote is held and in such vote the chairman of the Supervisory Board has a second vote. In order to constitute a quorum at least half of the total members of the Supervisory Board must be present in the meeting or participate in the voting by giving a written vote.

All of the current shareholder representatives on the Supervisory Board were elected by the shareholders at the annual meeting of shareholders held on April 26, 2002.

SUPERVISORY BOARD COMMITTEES

Currently, the Supervisory Board has the following committees:

- The nomination committee (Vermittlungsausschuss), established pursuant to sec. 27 (3) of the Co-Determination Act, consists of the chairman and vice chairman of the Supervisory Board, as well as one shareholder representative and one employee representative. The purpose of this committee is to nominate members of the Board of Management for election by a simple majority of the votes of the Supervisory Board in the event that the Supervisory Board is unable to appoint members of the Board of Management with the votes of at least a two thirds majority of the Supervisory Board.

84

Pursuant to sec. 5 (1) of the Standard Operating Procedures (Geschaftsordnung) of the Supervisory Board, the Vermittlungsausschuss also serves as the Presidium, i.e. a sub-body of the Supervisory Board to which the Supervisory Board may delegate some of its functions. Among the Presidium's responsibilities in this capacity is to advise the Supervisory Board as a whole in connection with the Supervisory Board's function as audit committee. The current members of the nomination committee are Mr. Schneider, Mr. Gipperich, Mr. von Pierer and Mr. Schmoldt.

- The personnel committee (Personalausschuss) established pursuant to sec. 5 (2) of the Standard Operating Procedures of the Supervisory Board. The personnel committee consists of four members of the Supervisory Board. The chairman of the Supervisory Board acts as chairman of the personnel committee. The main responsibility of the personnel committee is the determination of the salary and further conditions of the employment of Board of Management members, the legal representation of the Company in affairs with Board of Management members pursuant to sec. 112 of the German Stock Corporation Act, the approval of agreements with Supervisory Board members pursuant to sec. 114 of the German Stock Corporation Act and the approval of loans granted to Supervisory Board and Board of Management members and other persons pursuant to sec. 89 and sec. 115 of the German Stock Corporation Act. The current members of the personnel committee are Mr. Schneider, Mr. Gipperich, Mr. Kohlhaussen and Mr. de Win.

- The investment committee (Beteiligungsausschuss) established pursuant to sec. 5 (3) of the Standard Operating Procedures of the Supervisory Board. This committee consists of four members of the Supervisory Board; its primary purpose is to make recommendations to the Supervisory Board with respect to the acquisition or disposal of investments, where the Standard Operating Procedures of the Board of Management condition these transactions on the Supervisory Board's approval. The investment committee may grant preliminary approval to such transactions, thereby permitting the Board of Management to proceed with a transaction subject to final approval by the Supervisory Board.

- The social policy committee (sozialpolitischer Ausschuss) established pursuant to sec. 5(6) of the Standard Operating Procedures of the Supervisory Board. The social policy committee advises the Supervisory Board on developments in social policy in Germany and abroad that could be important for Bayer.

SHARE OWNERSHIP

Because the shares of Bayer AG are in bearer form, we cannot obtain precise information as to their holders. To the best of our knowledge, however, no member of the Supervisory Board or the Board of Management who beneficially owns shares of Bayer AG owns one percent or more of all outstanding shares.

COMPENSATION

In 2001, we paid salary and bonus compensation totaling E8,153,562 (2000:
E10,387,801) to the members of our Board of Management. Of this amount, E3,780,301 represented base salary and fixed bonus and E4,373,261 represented variable bonus. The variable bonus for a given year is tied to the amount of Bayer AG's dividend for that year. Emoluments to retired members of the Board of Management and their surviving dependents amounted to E8,355,270 (2000:
E8,923,934). We paid E1,293,750 (2000: E2,078,680) in compensation to the members of the Supervisory Board.

In 2000, we implemented our Stock Option Program, under which we may grant "option rights" to members of the Board of Management. The number of shares that these option rights entitle holders to receive will vary substantially depending on certain performance benchmarks; if minimum benchmarks are not reached, the holder is not entitled to exercise the option rights. See below, "-- Employee Option Plans -- Stock Option Program".

There were no loans to members of the Board of Management or Supervisory Board outstanding as of December 31, 2001.

85

We pay retired former members of the Board of Management a monthly pension equal to 80 percent of the monthly base salary received while in service. If we increase the base salary of current Board members, we adjust the pension payments to retired members accordingly.

BOARD OF MANAGEMENT SEVERANCE PLAN

Beginning in 2001, we established a severance plan for the members of Bayer AG's Board of Management. This plan provides for payments for Board members if their relationship with Bayer AG is terminated following a change of control. "Change of control", for the purposes of this plan, is defined as the acquisition by a third party of 25 percent or more of Bayer AG's outstanding shares or transactions that would have a similar effect. A Board member is generally eligible for payment under the plan if his or her relationship with Bayer AG ends within 12 months of the change of control, other than in the case of termination for cause or termination of a Board member aged 62 or more at the time of termination.

Under the plan, former Board members are entitled to receive the discounted present value of the compensation they would have received through the normal expiration date of their employment contracts. In addition, they would receive a severance payment equal to their annual compensation for a period of from two to four years. The basic amount of these severance payments is equal to two years' compensation. If the former Board member is 50 or older at the time of termination, the payment increases by one year's compensation or by two years' compensation if, in addition, the former Board member's length of service with the company was at least 30 years or his or her tenure on the Board was at least ten years. Total payments under the plan are, however, capped at an amount equal to five times the former Board member's annual compensation. In addition, the former Board member would retain full pension rights.

EMPLOYEE OPTION PLANS

In May 2000, we implemented a three-tier program to provide employees and management an opportunity to earn Bayer AG shares. We offer the stock option program for members of the Board of Management and senior executives, the stock incentive program for middle management and equivalent employees and the stock participation program for junior management and other employees.

To be eligible for the stock option and stock incentive programs and for Module 1 of the stock participation program, participants must place Bayer AG shares of their own into a special deposit account. Participants do not pay an exercise price for the shares they receive under these programs. Rather, they receive the shares as bonus shares or, in the case of Module 2 of the stock participation program, have the opportunity to purchase shares at a discounted price.

We may implement our employee option programs in annual tranches. Each tranche has separate terms, holding periods and other key parameters as described below, in each case keyed to the starting date of that tranche.

Stock Option Program

Members of the Board of Management and senior executives who wish to participate in the stock option program must place Bayer AG shares of their own in a special deposit account. We determine on an individual basis the maximum number of shares each participant may deposit; the participant receives one option right for each 20 shares deposited. These deposited shares are "locked up"; the participant may not sell them during the following three-year holding period. After the end of these three years, a two-year exercise period begins. During this period, the participant may exercise the option rights if he or she has fulfilled the performance criteria. Any unexercised option rights expire at the end of this two-year period.

We apply three criteria to determine whether the participant is eligible to exercise option rights granted in any given tranche and, if so, the number of shares received upon exercise. Two of these criteria measure the relative performance of the Bayer AG share; the third measures the individual contribution of the participant.

- If the Bayer AG share's total return has been at least 30 percent from the starting date of the tranche, each option right entitles the participant to one share for each three percentage points of total return, up

86

to a maximum of 50 shares. This number may be modified by the application of the third, individual performance-based criterion.

- If the Bayer AG share's total return exceeds the total return of the Dow Jones Euro Stoxx 50(SM) performance index since the starting date of the tranche, each option right entitles the participant to one share for each percentage point by which the Bayer AG share has outperformed the index, up to a maximum of 50 shares. Again, this number is subject to modification by the third criterion.

- We calculate the cash value the participant has added to the business operations for which he or she is responsible. We do this by comparing the average growth in cash value for these operations over that tranche's holding period with the average growth in cash value for the Bayer Group as a whole during the three years prior to the starting date of the tranche. The result of this calculation is a factor between 0 and 2.

We multiply the number of the participant's option rights by the number of shares to which he is or she is entitled under each the first two criteria. We then multiply the result by the factor produced by the third criterion. If the participant is not entitled to any shares under the first and second criteria, or if the factor produced by the third criterion is 0, the participant receives no shares under the program.

In 2001, participants in our stock option program have received a total of 1,639 option rights. The number of shares that these participants may receive upon exercise of their option rights would vary between a minimum of zero shares and, assuming maximum results for all participants on all three performance criteria described above, a maximum of 327,800 shares.

German law generally requires specific shareholder approval for the issuance of shares to members of a corporation's board of management. To the extent that we are unable to issue shares under the stock option program to participating members of our Board of Management at the time they are entitled to exercise their option rights, therefore, the option rights would function as share appreciation rights. Instead of shares, the participant would receive the cash value of the shares to which the option rights would otherwise entitle him or her, based on the trading price of the Bayer AG share at the time of exercise.

Stock Incentive Program

Like the stock option program, our stock incentive program for middle management requires participants to deposit Bayer AG shares in a special deposit account. In any given annual tranche, a participant may deposit Shares with a maximum aggregate value of half his or her performance-related bonus for the preceding fiscal year. The number of incentive shares the participant receives depends on the number of Bayer AG shares deposited at the start of the tranche as well as on the total return of the Bayer AG share. Unlike the stock option program, the stock incentive program does not "lock up" deposited shares. Participants may sell their deposited shares during the term of the tranche, but any deposited shares they sell are no longer counted in calculating the number of incentive shares for subsequent distribution dates.

Each tranche of the stock incentive program has a ten-year term. There are three incentive share distribution dates during this period. On these dates, the participant receives incentive shares as follows:

                                                          INCENTIVE SHARES RECEIVED
DISTRIBUTION DATE AT END OF                               (PER 10 DEPOSITED SHARES)
---------------------------                               -------------------------
Second year............................................               2
Sixth year.............................................               4
Tenth year.............................................               4

Participants receive incentive shares only if the total return of the Bayer AG share has outperformed the Dow Jones Euro Stoxx 50(SM) performance index on the relevant distribution date, as calculated from the starting date of the tranche.

Based on the number of Bayer AG shares that participants in the stock incentive program deposited in the tranche for 2001, participants are eligible to receive a total of 80,380 shares on the tranche's future distribution

87

dates, assuming satisfaction of the performance criterion on each such date and assuming that these participants do not remove any shares from deposit during the term of the tranche.

Stock Participation Program

Our stock participation program has two components, Module 1 and Module 2. Employees not covered by the stock option program or stock incentive program may generally participate in both Module 1 and Module 2.

The Module 1 program, like the stock incentive program, requires participants to deposit Bayer AG shares in a special account. As with the stock incentive program, participants in the stock participation program may sell their deposited Bayer AG shares during the term of the tranche; any shares they sell are no longer counted in calculating the number of bonus shares on subsequent distribution dates for that tranche. Participants may deposit shares in a total value equal to half their performance-related bonus for the previous year.

Each tranche of Module 1 has a term of ten years and entitles the participant to receive incentive shares on three distribution dates based on the number of shares he or she has deposited. Unlike the stock incentive program, Module 1 does not impose a share performance criterion. The participant receives incentive shares as follows on the distribution dates:

                                                          INCENTIVE SHARES RECEIVED
DISTRIBUTION DATE AT END OF                               (PER 10 DEPOSITED SHARES)
---------------------------                               -------------------------
Second year............................................               1
Sixth year.............................................               2
Tenth year.............................................               2

Based on the number of Bayer AG shares that participants in Module 1 of the stock participation program have deposited in the tranche for 2001, participants are eligible to receive a total of 322,180 shares on the future distribution dates, assuming that these participants do not remove any shares from deposit during the term of the tranche.

LABOR RELATIONS

The union-organized workers at our German facilities belong to several unions, the most important of which is IG BCE, the German Mine, Chemical and Power Workers' Union. We do not negotiate collective bargaining agreements with these unions to cover our workers. Instead, in accordance with German practice, unions

88

negotiate agreements with industry-wide employers' associations, in our case the German Chemical Industry Association.

In Germany, employers and unions generally negotiate collective bargaining agreements annually. The current agreement that covers our workers has a term of 13 months, beginning April 2002. It grants workers a lump-sum payment of E85 in the first month of the agreement and a subsequent 3.3 percent pay increase over the life of the agreement. A German collective bargaining agreement governs the employment of all workers of the categories organized in the relevant union, whether or not the individual worker is a union member.

There are 13 pay grades, based on job description, for our employees in positions governed by collective bargaining agreements. Our management employees, who have individual employment contracts, are organized in six pay grades.

Each Bayer facility in Germany has a works council (Betriebsrat), elected by all non-management employees. Members serve a four-year term; the last elections took place in March 2002. The works councils facilitate communications between us and our staff at the facility level. A joint works council (Gesamtbetriebsrat) serves a similar purpose at the company-wide level. The rights and responsibilities of works councils are set forth in the German Works Council Constitution Act (Betriebsverfassungsgesetz). Members of our works councils share responsibility with us for managing staff-related issues as well as such working conditions as:

- working hours;

- vacation guidelines;

- employee facilities (e.g., subsidized cafeterias); and

- distribution guidelines for performance-related bonuses.

A works council has no authority, however, to negotiate with an employer on wage and salary compensation or other issues covered by the collective bargaining agreements between employers' associations and labor unions. Under German labor law, employees may legally strike only in an effort to obtain more favorable terms in the collective bargaining process. Accordingly, works councils have no legal authority to call a work stoppage.

On December 12, 2000 we entered into an agreement (Standortsicherungsvereinbarung) with our joint works council to further job stability at several of our most important German sites. This agreement became effective on January 1, 2001. Under the agreement, the joint works council agreed to the reduction or elimination of certain social benefits that we previously provided. These included additional vacation days, additional payments and paid breaks. The council also granted us increased flexibility in setting working hours. In exchange, we agreed that we would not, except in exceptional circumstances, lay off employees at our Leverkusen, Dormagen, Uerdingen, Elberfeld and Brunsbuttel sites for operational reasons before December 31, 2004. If exceptional circumstances arise that are beyond our control and lead to employee overcapacity, we have agreed to negotiate with the joint works council to create a solution that will serve the interests of company and employees to the greatest possible extent.

EMPLOYEE PENSION PLAN

All employees who have not reached the age of 55 before entering into employment with Bayer AG must join Bayer AG's pension fund (Bayer-Pensionskasse). As a member of the Pensionskasse, an employee makes a monthly contribution to the pension fund. These contributions are withheld from the member's salary. Bayer AG also contributes to the Pensionskasse. Upon retirement, the employee is entitled to receive a monthly basic pension payment (Grundrente) from the Pensionskasse if the employee was employed by Bayer AG, or was a member of the Pensionskasse, for at least five years. Employees whose annual salary exceeds the annual salary threshold for statutory pension insurance (gesetzliche Rentenversicherung) are entitled to receive an additional monthly pension payment (Zusatzrente). As of December 2001, this salary threshold was E53,378. Bayer AG finances these additional pension payments in total by pension reserves.

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

MAJOR SHAREHOLDERS

Under our Articles of Association, each of our ordinary shares represents one vote. Major shareholders do not have different voting rights.

Under the German Securities Trading Act (Wertpapierhandelsgesetz), holders of voting securities of a listed German company must notify that company of the level of their holding whenever it reaches, exceeds or falls below specified thresholds. These thresholds are 5, 10, 25, 50 and 75 percent of the company's outstanding voting securities. One shareholder, Allianz Versicherungs-Aktiengesellschaft, has informed us that it holds 5.92 percent of Bayer AG's outstanding shares. No other shareholder has notified us that it has crossed any of the Securities Trading Act's thresholds.

Because the shares of Bayer AG are in bearer form, we cannot obtain precise information as to the identity of shareholders or the distribution of the shares among them. From time to time, however, we conduct surveys, using the assistance of banks, to form estimates as to Bayer AG's shareholder base. Our last such survey measured our shareholder structure as of June 1, 2001. The survey recorded responses with respect to 95.6 percent of our approximately 500,000 shareholders. Of this number, 94 percent were individuals, who together owned 24 percent of the shares. Approximately 55,000, or 12 percent, of the individual shareholders were Bayer employees, who together held approximately 2 percent of Bayer AG's outstanding shares. Institutional investors (e.g., banks, insurance companies and investment funds) held another 67 percent of the shares. Shareholders in Germany numbered approximately 437,000 and owned 61 percent of the shares. Approximately 59,000 shareholders in 135 other countries held 39 percent of the shares. Of this group, British shareholders held approximately 10 percent, and U.S. shareholders about 8 percent, of the shares.

To our knowledge, we are not directly or indirectly owned or controlled by another corporation or by any government, and there are no arrangements which may result in a change of control.

See also "Share Ownership" in Item 6, Directors, Senior Management and Employees.

RELATED PARTY TRANSACTIONS

In the ordinary course of business, we purchase materials, supplies and services from numerous companies throughout the world. Members of Bayer AG's Supervisory Board are affiliated with some of these companies. We conduct our transactions with such companies on an arm's length basis. We do not consider the amounts involved in such transactions to be material to our business and believe that these amounts are not material to the business of the companies involved.

During our three most recent complete financial years and through the date of this annual report, we have not been involved in, and we do not currently anticipate becoming involved in, any transactions that are material to us or any of our related parties and that are unusual in their nature or conditions. We have not made any outstanding loans to or for the benefit of:

- enterprises that, directly or indirectly, control or are controlled by, or are under common control with us;

- enterprises in which we have significant influence or which have significant influence over us;

- shareholders beneficially owning a 10 percent or greater interest in our voting power;

- key management personnel; or

- enterprises in which persons described above own, directly or indirectly, a substantial interest in the voting power.

See Item 18.

LEGAL PROCEEDINGS

Bayer is involved in a number of legal proceedings. As a global company active in a wide range of life sciences and chemical activities, we may in the normal course of our business become involved in proceedings relating to such matters as:

- product liability;

- patent validity and infringement disputes;

- tax assessments;

- competition and antitrust; and

- past waste disposal practices and release of chemicals into the environment.

We cannot predict with certainty the outcome of any proceedings in which we are or may become involved. An adverse decision in a lawsuit seeking damages from us could result in a monetary award to the plaintiff and, to the extent not covered by our insurance policies, could significantly harm our business or the result of our operations. If we lose a case in which we seek to enforce our patent rights, we could sustain a loss of future revenue as other manufacturers begin to market products we developed.

In the remainder of this subsection, we describe what we believe to be the most significant of the proceedings in which Bayer AG or its subsidiaries are currently involved.

PATENT VALIDITY CHALLENGES AND INFRINGEMENT PROCEEDINGS; PATENT-RELATED ANTITRUST ACTIONS

In the United States, Bayer AG and its U.S. subsidiary Bayer Corporation are plaintiffs or co-plaintiffs in a number of patent infringement actions against generic drug manufacturers. The lawsuits arose because these manufacturers filed applications in the United States for regulatory approval of generic versions of products containing the active ingredients ciprofloxacin or nifedipine marketed by Bayer or its licensees. Some of these actions have, in turn, given rise to lawsuits alleging that Bayer AG, Bayer Corporation and other parties had violated federal and state antitrust and similar statutes.

Generic drug manufacturers may receive approval to market formerly patented products after all applicable patent protections have expired. A generic drug manufacturer may, however, attempt to avoid a patent prior to its scheduled expiry by attacking its validity or enforceability. In the United States, the Federal Food, Drug, and Cosmetics Act enables generic manufacturers wishing to market a bio-equivalent version of another manufacturer's product to seek regulatory approval by filing an Abbreviated New Drug Application (ANDA). In its ANDA the applicant must state the basis on which it seeks to avoid any applicable patents.

One basis for seeking approval is a claim that the applicant's product does not infringe existing patent rights or that the patent is invalid or unenforceable. This claim is commonly known as a "paragraph IV certification" or "ANDA (IV)." Under the Act, the filing of a paragraph IV certification is deemed an infringement of patent rights. The Act permits the holder of the patent rights to file an infringement action against the ANDA applicant within 45 days of receiving notice of the paragraph IV certification. If the holder of the patent rights chooses not to file suit within this period, the FDA may approve the ANDA immediately. The filing of a suit, however, stays final FDA approval of the ANDA for a period of 30 months. The court may shorten or extend this period. If the court rules that the applicant's product will not infringe the patent or that the patent is invalid or unenforceable, the FDA may grant approval immediately. If, on the other hand, the court rules that the product will infringe the patent, the FDA may not grant final approval until the original patent has expired.

91

Ciprofloxacin-related actions

Patent-related actions. In January 1997, Bayer AG and Bayer Corporation settled a patent infringement suit against Barr Laboratories, Inc. This suit arose when Barr filed an ANDA (IV) seeking regulatory approval of a generic form of Bayer's ciprofloxacin anti-infective product, which we sell in the United States under the trademark Cipro(R). Under the settlement agreement, Barr and Rugby Laboratories Inc., another generic manufacturer that supported Barr during the infringement suit, agreed to dismiss the litigation, acknowledging the validity and enforceability of Bayer's patent rights, and we agreed to pay each company $24.5 million. The agreement gave us the option, until our patent expires in 2003, to supply Barr and Rugby's then parent company Hoechst Marion Roussel Inc. with ciprofloxacin products which they could then market under a license from Bayer using a single trade name, or else to make quarterly cash payments. Since concluding the settlement agreement, we have opted to make payments. Shortly after settling this suit, we applied to the U.S. Patent and Trademark Office for a reexamination of our patent. The Patent and Trademark Office reissued the patent in February 1999.

In April 1999, Danbury Pharmacal Inc., an affiliate of Schein Pharmaceutical, Inc., filed an ANDA (IV) alleging that our ciprofloxacin patent was invalid. Mylan Pharmaceuticals, Inc., an affiliate of Mylan Laboratories, Inc., filed an ANDA (IV) challenging our ciprofloxacin patent in September 1999. To protect and enforce our patent rights, Bayer AG together with Bayer Corporation as licensee filed two lawsuits against Danbury Pharmacal and Schein Pharmaceutical and one lawsuit against Mylan Pharmaceuticals and Mylan Laboratories in 1999, and a second lawsuit against Mylan Pharmaceuticals and Mylan Laboratories in 2000. Reddy Cheminor, Inc. intervened as an additional defendant in the Danbury/Schein suits. All these suits were consolidated for pre-trial proceedings and trial before the U.S. federal District Court for the District of New Jersey.

In their responses the defendants alleged the invalidity and unenforceability of our reexamined patent on several grounds. They then moved for summary judgment on the invalidity issue, and we filed a cross-motion for partial summary judgment. In February 2001, the district court denied the defendants' motion and granted our cross-motion. The court subsequently entered a final judgment in our favor, confirming the validity and enforceability of the patent. The defendants appealed this judgment to the Court of Appeals for the Federal Circuit, which heard oral arguments on January 7, 2002.

In addition, Bayer AG and Bayer Corporation filed a patent infringement action in May 2001 against Carlsbad Technology, Inc., arising from Carlsbad's ANDA (IV) filing seeking regulatory approval of its generic version of Cipro(R). Carlsbad filed two motions for summary judgment. The first motion alleged as a matter of patent procedure that Bayer's patent as it relates to ciprofloxacin should expire in October 2002 and not, as determined by the Patent and Trademark Office, in December 2003. Bayer filed a cross-motion for summary judgment that the expiration date is in December 2003. In its second motion, Carlsbad alleged that ciprofloxacin was obvious in light of the prior art. The federal District Court for the Southern District of California denied both Carlsbad motions in October, 2001 and granted summary judgment to Bayer on its cross-motion. Carlsbad has appealed the decision denying the first motion to the Court of Appeals for the Federal Circuit. A trial regarding the arguments of obviousness raised in Carlsbad's second motion was held in April and May 2002. The court has not yet made a ruling. Carlsbad has withdrawn all other defenses it had originally raised challenging the validity and enforceability of Bayer AG's ciprofloxacin patent.

If we lost our patent protection for ciprofloxacin, or if the expiration of the patent were accelerated to October 2002, we believe that we would forego significant revenue. We intend to continue taking vigorous action to maintain our ciprofloxacin patent rights in the United States through their normal expiry in December 2003.

Antitrust actions. Bayer Corporation has been named as a defendant in 39 putative class action lawsuits, one individual lawsuit and one consumer protection group lawsuit filed in a number of state and federal courts in the United States. Bayer AG has also been named as defendant in twenty of these cases, including the individual lawsuit and the consumer protection group lawsuit; it has been served with process in the individual lawsuit and twelve of the putative class action lawsuits. In addition, Barr Laboratories, Aventis S.A., Hoechst Marion Roussel, Inc., Rugby Laboratories, Inc. and Watson Pharmaceuticals, Inc. have each been named as defendant in one or more of these lawsuits. The plaintiffs in these suits allege that they are direct or indirect purchasers of Cipro(R) who were damaged because Bayer's settlement of the Barr ANDA (IV) litigation prevented generic

92

manufacturers from selling a generic version of Cipro(R). The plaintiffs allege that the defendants violated various federal antitrust and state business, antitrust, unfair trade practices and consumer protection statutes, and seek treble damages and injunctive relief.

These proceedings are at an early stage. None of the relevant courts have certified a class. The Judicial Panel for Multidistrict Litigation, or MDL Panel, transferred 35 of these cases to the U.S. federal District Court for the Eastern District of New York for coordinated pre-trial proceedings. The federal court ordered nine of those cases remanded to various state courts in October 2001. Nine cases are currently pending in a California state court. Bayer is also involved in state court proceedings occurring in Florida, New York, Kansas, Tennessee and Wisconsin.

The Barr settlement is also the subject of ongoing antitrust investigations by the U.S. Federal Trade Commission and a number of state attorneys general.

Because these cases in the aggregate allege substantial unquantified damages and also seek treble and punitive damages and penalties, it is possible that the ultimate liability could be material to our results of operations and cash flows. Although we cannot predict the outcome of these cases with certainty, we believe that we have meritorious defenses to the antitrust allegations and intend to defend them vigorously.

Nifedipine-related actions

Patent-related actions. Since 1997 Bayer AG and Bayer Corporation have been involved in a number of patent infringement actions arising from ANDA (IV)s filed by generic manufacturers seeking regulatory marketing approval for allegedly bio-equivalent versions of our brand-name product Adalat(R) CC and Pfizer, Inc.'s brand-name product Procardia(R) XL. The active ingredient of these products is nifedipine. We own patent rights related to nifedipine drug product formulations. In addition, because Pfizer markets Procardia(R) XL under a license from Bayer, Bayer AG and Bayer Corporation became Pfizer's co-plaintiffs in the infringement actions relating to that product.

In August 1997, Bayer AG and Bayer Corporation filed a patent infringement suit against Elan Pharmaceutical Research Corp. and Elan's parent company, Elan Corp., plc, arising from Elan's ANDA (IV) for a drug product containing nifedipine in a 30mg dosage form. In March 1999, the U.S. federal District Court for the Northern District of Georgia granted summary judgment against us, holding that the particular generic product for which Elan sought marketing approval as described in its ANDA would not violate our patent. In May 2000, the U.S. Court of Appeals for the Federal Circuit affirmed this decision.

In March 2001, the same district court granted summary judgment against Bayer AG and Bayer Corporation in a second ANDA (IV) related suit (60 mg dosage form) that we had filed against Elan and later in another action that we had filed against Elan, Biovail Labs, Inc., Biovail Corp. International and Teva Pharmaceuticals USA, Inc., arising from these parties' commercial sale of an allegedly bio-equivalent nifedipine product. We appealed these decisions to the Court of Appeals for the Federal Circuit. The Federal Circuit vacated these decisions of the District Court and remanded the cases to the District Court for further proceedings.

Bayer AG and Bayer Corporation have also filed four ANDA (IV) related lawsuits against Biovail and two lawsuits arising from the commercial sale of nifedipine products by Biovail and Teva. These suits are currently stayed before the U.S. federal District Court for the District of Puerto Rico.

As defendants have prevailed in some of these lawsuits, it is possible that they may also prevail in the trials and appeals that may take place in the future. We believe, however, that we have meritorious claims in the pending cases, and intend to prosecute these claims vigorously. Because some of our nifedipine dosages have already begun to face generic competition, we do not believe that an adverse result in the pending cases would result in a material amount of additional foregone revenue.

Antitrust actions. Biovail has filed an antitrust lawsuit against Bayer AG, Bayer Corporation and Pfizer in the U.S. federal District Court for the District of Western Pennsylvania. Biovail is seeking a declaratory judgment that Bayer's nifedipine patents are invalid. Biovail also seeks damages under federal and state antitrust statutes

93

alleging, among other things, that Bayer illegally asserted its patent rights. The district court has stayed this litigation pending resolution of the nifedepine-related patent infringement actions against Biovail.

This proceeding is at an early stage. However, we believe that we have meritorious defenses to the antitrust allegations, and we intend to defend this case vigorously.

PRODUCT LIABILITY PROCEEDINGS

HIV-related actions. During the past decade, our U.S. subsidiary Bayer Corporation, as well as other fractionators of plasma products, have been involved in lawsuits alleging that hemophiliacs became infected with the human immunodeficiency virus (HIV), or ultimately developed AIDS, by using clotting factor concentrates derived from human plasma. Plaintiffs have brought actions on these grounds in the United States, Ireland, Italy, Taiwan, Argentina, Canada, Japan, and Germany.

In the United States, a class action against Bayer Corporation and three other defendants consolidated the HIV-related claims of more than 6,000 claimants and claimant groups. The parties resolved this class action through a $600 million settlement. Bayer Corporation's share of this settlement was approximately $290 million. Bayer Corporation has also satisfactorily settled nearly 400 lawsuits by plaintiffs who opted out of the class action. Seven suits remain pending in the United States. Although Bayer Corporation has prevailed in the majority of cases that have proceeded to trial, plaintiffs were successful in three cases. The juries in each of these cases awarded damages not exceeding $2 million. In addition, in 1999, a Louisiana jury awarded a plaintiff damages of $35 million. However, the trial court set this award aside, and an appellate court upheld this decision. Bayer Corporation has since settled this matter in the context of a group settlement of nearly 100 Louisiana cases, of which Bayer Corporation's share was less than $50 million.

Although Bayer Corporation intends to defend aggressively the remaining HIV-related lawsuits in various countries, we have made what we believe to be appropriate provisions should these suits result in judgments in favor of the plaintiffs. These provisions are not material to the Bayer Group.

Cerivastatin-related actions. In August 2001, we voluntarily ceased marketing our cerivastatin anticholesterol products in response to reports of serious side effects in some patients. See Item 4, Information about the Company -- Health Care -- Pharmaceuticals -- Products. Since this withdrawal, about 1,700 lawsuits, many of them putative class actions, have been initiated in the United States against Bayer Corporation and Bayer AG. The actions in the United States have been primarily on theories of product liability, consumer fraud, medical monitoring, predatory pricing and unjust enrichment. These lawsuits seek remedies including compensatory and punitive damages, disgorgement of funds received from the marketing and sale of cerivastatin and the establishment of a trust fund to finance the medical monitoring of former cerivastatin users. The federal cases are being transferred to the U.S. federal District Court for the District of Minnesota for coordinated discovery and other pre-trial proceedings. In addition, several actions have been initiated against other companies of the Bayer Group in other countries. We expect additional lawsuits to be filed in the United States and elsewhere. If the plaintiffs in these actions were to be successful, it is possible that the ultimate liability could be material to our results of operations and cash flows. We believe that we have meritorious defenses in these actions and are defending them vigorously. Without acknowledging any liability, we have settled a small number of these cases in the past. We may, on a case-by-case basis, settle additional cases for reasonable amounts when, in our judgment, settlement is economically feasible given the risks and costs inherent in any litigation.

Phenylpropanolamine (PPA) actions. In late 2000, Bayer Corporation discontinued marketing Alka-Seltzer Plus effervescent medicines containing PPA in the United States, Canada and various Latin American countries in response to a recommendation from the U.S. Food and Drug Administration to all manufacturers of drugs and medicines containing PPA. The FDA issued this recommendation after one epidemiological study of a small number of patients suggested a possible association between PPA and hemorrhagic stroke in women of certain ages. More than 540 class and individual lawsuits have been initiated in the United States against Bayer Corporation. The MDL Panel has assigned management of the federal court cases to the U.S. federal District Court for the Western District of Washington. It is probable that additional actions will be initiated there or in other jurisdictions where products containing PPA were marketed. Bayer Corporation believes it has meritorious defenses to these actions and intends to defend them vigorously.

94

MEDICAID REBATE PROGRAM ALLEGATIONS

Our U.S. subsidiary, Bayer Corporation, is currently under investigation by the U.S. Attorney's Office for the District of Massachusetts. The investigation, which is assisted by the Department of Health & Human Services, focuses primarily on allegations that Bayer Corporation improperly underpaid rebates under the Medicaid Rebate Program during a period from 1995 to 2000.

These investigations could lead the government to bring criminal or civil actions, or both, against Bayer Corporation. If the government brought such actions and obtained a conviction or verdict against Bayer Corporation, we would likely be required to reimburse the government the amount of the alleged underpayment. We would also become liable to pay civil and/or criminal fines or penalties, which could be substantial. Although we believe this outcome to be unlikely, in the worst case a conviction or adverse verdict could result in the exclusion of Bayer Corporation from participation in federal health programs. Bayer Corporation is providing information to the government and otherwise cooperating with the investigation. Bayer Corporation believes that its practices complied in all material respects with all applicable laws and is therefore seeking to persuade the government to discontinue its investigation. If the government does bring civil or criminal charges against Bayer Corporation, Bayer Corporation intends to defend itself vigorously.

AVERAGE WHOLESALE PRICE MANIPULATION PROCEEDINGS

Seven pending lawsuits allege that a number of pharmaceutical companies, including Bayer Corporation, manipulated the average wholesale price of their products. The suits allege that this manipulation resulted in overcharges to Medicare beneficiaries, Medicaid recipients, state governmental health programs, and private health plans. These suits generally seek damages, treble damages, disgorgement of profits, restitution and attorney's fees. We expect that six of these actions will be consolidated before the U.S. federal court for the District of Massachusetts. The remaining case, in which the State of Nevada is plaintiff, has been removed to federal court in Nevada but may be subject to remand to a state court. Bayer Corporation has not yet responded to the complaints in these actions, but intends to defend itself vigorously.

DIVIDEND POLICY AND LIQUIDATION PROCEEDS

Our shareholders may declare dividends at an ordinary general shareholders' meeting, which must be held within the first eight months of each fiscal year.

Under German law, Bayer AG may pay dividends only from balance sheet profits reflected in its unconsolidated financial statements (as opposed to the consolidated financial statements of the Bayer Group), as adopted and approved by the Board of Management and the Supervisory Board. In determining the balance sheet profits that may be distributed as dividends, the Board of Management may under German law allocate to retained earnings (Gewinnrucklagen) up to 50 percent of the net income of Bayer AG for the fiscal year that remains after deducting amounts to be allocated to legal and statutory reserves and losses carried forward. The Board of Management may also increase balance sheet profits when preparing the financial statements with funds withdrawn from retained earnings.

Our shareholders, in their resolution on the appropriation of balance sheet profits, may carry forward balance sheet profits in part or in full and may allocate additional amounts to retained earnings. Profits carried forward will be automatically incorporated in the balance sheet profits of the next fiscal year and may be used in their entirety to pay dividends in the next fiscal year. Amounts allocated to the retained earnings are available for dividends only if and to the extent the retained earnings have been dissolved by the Board of Management when preparing the financial statements, thereby increasing the balance sheet profits.

Dividends approved at an ordinary general shareholders' meeting are payable promptly after the meeting, unless otherwise decided at the meeting. Because all of Bayer AG's shares are in book-entry form represented by a global certificate deposited with Clearstream Banking AG in Frankfurt am Main, Germany, shareholders receive dividends through Clearstream for credit to their deposit accounts.

We expect to continue to pay dividends, although we can give no assurance as to the payment of a dividend for any particular year or as to the particular amounts that we may pay from year to year.

95

Apart from liquidation as a result of insolvency proceedings, Bayer AG may be liquidated only with a combined majority of the votes cast and three-quarters of the share capital present or represented at a shareholders' meeting at which the vote is taken. In accordance with the German Stock Corporation Act, upon a liquidation of Bayer AG, any liquidation proceeds remaining after paying off all of Bayer AG's liabilities would be distributed among the shareholders in proportion to the total number of shares held by each shareholder.

See also "Dividends" in Item 3, Key Information.

ITEM 10. ADDITIONAL INFORMATION

DESCRIPTION OF SHARE CAPITAL

For a description of material provisions of Bayer AG's articles of association (Satzung), including a discussion of the voting, dividend and other rights of shareholders, see our Registration Statement on Form 20-F as filed with the Securities and Exchange Commission on January 15, 2002.

Because the current authorized capital I and II as described in the Registration Statement were scheduled to expire on April 30, 2002, our shareholders created a new authorized capital I and II at their annual meeting on April 26, 2002. The new authorized capital I is in the amount of E150,000,000 and the new authorized capital II is in the amount of E100,000,000. Both authorizations are valid through April 26, 2007. The terms of the new authorized capital I and II are otherwise substantially identical to those described in our Registration Statement. The new authorized capital I and II will become effective upon recordation of the shareholders' resolutions in the commercial register. We expect that the district court (Amtsgericht) at Leverkusen, which maintains the commercial register that includes Bayer, will effect the recording of our authorized capital within approximately 8 to 10 weeks after the shareholders' meeting.

At their April 26, 2002 annual meeting, the shareholders also extended until October 25, 2003 the Board of Management's authorization to repurchase Bayer AG shares. The Board of Management is authorized to repurchase shares for such purposes as distribution to members of the management who are not Board members and to employees of Bayer Group companies in connection with share option programs. See "Employee option plans" in Item 6, Directors, Senior Management and Employees -- Compensation.

MATERIAL CONTRACTS

In connection with our planned acquisition of Aventis CropScience, we entered into two Stock Purchase Agreements, each dated October 2, 2001, with the current shareholders of Aventis CropScience. The first agreement was with Aventis S.A. and Hoechst AG. The second was with Schering AG and SCIC Holdings
LLC. Exhibits 4.1 and 4.2 to this Annual Report incorporate by reference these agreements as previously filed with the Commission.

We are not otherwise party to any contracts that we regard as material to our business or financial position.

EXCHANGE CONTROLS

There are currently no German foreign exchange control restrictions on the payment of dividends on the shares or the conduct of our operations.

TAXATION

The following is a discussion of the material U.S. federal income and German tax consequences to you as a Qualified Holder of Bayer AG shares. This discussion is based upon existing U.S. federal income and German tax law, including legislation, regulations, administrative rulings and court decisions, as in effect on the date of this annual report, all of which are subject to change, possibly with retroactive effect.

For the purposes of this discussion, you are a "Qualified Holder" if you are the beneficial owner of ordinary Bayer AG shares and (1) are a resident of the United States for purposes of the Convention Between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital, as amended (the "Income Tax Treaty"), which generally includes an individual U.S. resident, a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia and a partnership, estate or trust, to the extent its income is subject to taxation in the United States as the income of a U.S. resident, either in its hands or in the hands of its partners or beneficiaries, (2) do not hold Bayer AG shares as part of the business property of a permanent establishment located in Germany or as part of a fixed base located in Germany and used for the performance of independent personal services and (3) if you are not an individual, are not subject to the limitation on benefits restrictions in the Income Tax Treaty. This discussion assumes that you hold Bayer AG shares as a capital asset.

98

This discussion does not address all aspects of U.S. federal income and German taxation that may be relevant to you in light of your particular circumstances. For example, this discussion does not apply to Qualified Holders whose shares were acquired pursuant to the exercise of an employee share option or otherwise as compensation or who are subject to special treatment under U.S. federal income tax laws such as financial institutions, insurance companies, tax-exempt organizations, holders of 10 percent or more of Bayer AG shares, broker-dealers in securities or/currencies, persons that hold Bayer AG shares as part of a "hedging" or a "conversion" transaction or as a position in a "straddle", and persons whose functional currency is other than the U.S. dollar. This discussion also does not address any aspects of state, local or non-U.S. (other than certain German) tax law. If a partnership holds Bayer AG shares, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If a Qualified Holder is a partner in a partnership that holds Bayer AG shares, the Holder is urged to consult its own tax advisor regarding the specific tax consequences of the purchase, ownership and disposition of the Bayer AG shares.

In general, for U.S. federal income tax purposes, if you are a Qualified Holder of ADRs evidencing ADSs, you will be treated as the owner of the Bayer AG shares represented by such ADSs. Unless the context requires otherwise, all references in this section to Bayer "shares" are deemed to refer likewise to ADSs evidencing an ownership interest in Bayer AG shares.

WE URGE YOU TO CONSULT YOUR TAX ADVISOR AS TO THE U.S. FEDERAL INCOME AND GERMAN TAX CONSEQUENCES OF HOLDING BAYER AG SHARES, INCLUDING THE PARTICULAR FACTS AND CIRCUMSTANCES THAT MAY BE UNIQUE TO YOU, AND AS TO ANY OTHER TAX CONSEQUENCES OF HOLDING BAYER AG SHARES.

TAXATION OF DIVIDENDS

As of January 1, 2002, we are required to withhold tax on dividends in respect of the 2001 fiscal year an amount equal to 20 percent of the gross amount paid to resident and non-resident shareholders. As a Qualified Holder, you are eligible to receive a partial refund of this withholding tax under the Income Tax Treaty (subject to certain limitations), effectively reducing the withholding tax to 15 percent of the gross amount of the dividend. Thus, for each $100 of gross dividend paid by Bayer AG to you, the dividend will be subject to a German withholding tax of $15 under the Income Tax Treaty. The cash received per $100 of gross dividend will thus be $85. For U.S. federal income tax purposes, the gross amount of the dividend, including German withholding tax, will be includible in your gross income. You will not be entitled to the dividends received deduction with respect to any dividends we pay.

A surtax on the German withholding tax is currently levied on dividend distributions paid by a German resident company. The rate of this surtax is 5.5 percent. The surtax amounts to 1.375 percent (5.5 percent x 25 percent) of the gross dividend amount. The surtax will equal 1.1 percent (5.5 percent x 20 percent) of the gross dividend paid out in 2002 and thereafter. Under the Income Tax Treaty, you will be entitled to a full refund of this surtax.

Dividends paid to you in euros will be included in income in a U.S. dollar amount, calculated by reference to the exchange rate in effect on the date the dividends are received or treated as received by you. If you convert dividends paid in euros into U.S. dollars on the date received or treated as received, you generally should not be required to recognize foreign currency gain or loss in respect of such dividend.

Under Section 904(g) of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), dividends paid by a foreign corporation that is treated as more than 50 percent owned by U.S. persons may be treated as U.S. source income (rather than foreign source income). Such treatment may adversely affect Qualified Holders' ability to use foreign tax credits. It is possible that we may be treated as more than 50 percent owned by United States persons for the purposes of Section 904(g) of the Code.

The United States Treasury has expressed concerns that parties to whom ADSs are released may be taking actions that are inconsistent with the claiming of foreign tax credits for Qualified Holders of ADSs. Accordingly, the creditability of German withholding tax on dividends could be affected by future actions that may be taken by the United States Treasury.

99

REFUND PROCEDURES

To claim the refund reflecting the reduction of the German withholding tax from 20 percent to 15 percent and the refund of the 5.5 percent German surtax, when applicable, you must submit (either directly, or, as described below, through our U.S. transfer agent or the Depository Trust Company) a claim for refund to the German tax authorities, with the original bank voucher (or a certified copy thereof) issued by the paying entity documenting the tax withheld within four years from the end of the calendar year in which the dividend is received. Claims for refunds are made on a special form, which must be filed with the German tax authorities at the following address: Bundesamt fur Finanzen, 53221 Bonn-Beuel, Germany. A refund claim form may be obtained from the German tax authorities at the same address as where applications are filed, from the Embassy of the Federal Republic of Germany, 4645 Reservoir Road, N.W., Washington, D.C. 20007-1998 or from the Office of International Operations, Internal Revenue Service, 1325 K Street, N.W., Washington, D.C. 20225, Attention: Taxpayer Service Division, Room 900.

You must also submit to the German tax authorities certification of your last filed U.S. federal income tax return (IRS Form 6166). You can obtain this certification from the office of the Director of the Internal Revenue Service Center by filing a request for certification with the Internal Revenue Service Center in Philadelphia, Pennsylvania, Foreign Certificate Request, P.O. Box 16347, Philadelphia, PA 19114-0447. Requests for certification must be made in writing and must include your name, social security number or employer identification number, tax return form number and tax period for which you are requesting certification. The Internal Revenue Service will send the certification directly to the German tax authorities. This certification is valid for three years and need only be resubmitted in a fourth year in the event of a subsequent application for refund. IRS Publication 686 describes the certification procedure in more detail.

Our U.S. transfer agent will perform administrative functions necessary to claim the refund reflecting the reduction in German withholding tax from 20 percent to 15 percent and the refund of the 5.5 percent German surtax, when applicable, for you. However, these arrangements may be amended or revoked at any time in the future. Under the current procedure, the U.S. transfer agent will prepare the German claim for refund forms on your behalf and file them with the German tax authorities. In order for the U.S. transfer agent to file the claim for refund forms, the U.S. transfer agent will prepare and mail to you, and will ask that you sign and return to the U.S. transfer agent, (1) a statement authorizing the U.S. transfer agent to perform these procedures and agreeing that the German tax authorities may inform the Internal Revenue Service of any refunds of German taxes and (2) a written authorization to remit the refund of withholding to an account other than yours. The U.S. transfer agent will also require certification of your last filed United States federal income tax return (IRS Form 6166). The U.S. transfer agent will attach the signed statement, the IRS Form 6166 and the documentation issued by the paying agency documenting the dividend paid and the tax withheld to the claim for refund form and file them with the German tax authorities.

A simplified refund procedure will be available to you if your Bayer AG shares are registered with brokers participating in the Depository Trust Company. Under this simplified refund procedure, the Depository Trust Company will provide the German tax authorities with electronic certification of your U.S. taxpayer status based on information it receives from its broker participants, and will claim a refund on your behalf. If approved by the German tax authorities, a similar simplified refund procedure may also be implemented by the U.S. transfer agent in the future. Under such a simplified refund procedure, following each dividend payment, the U.S. transfer agent would file a claim for refund automatically on your behalf if you have instructed the U.S. transfer agent in writing to file on your behalf.

The German tax authorities will issue refunds denominated in euro. The refunds will be issued in the name of the U.S. transfer agent or the Depository Trust Company, as the case may be, which will then convert the refunds to dollars and make corresponding refund payments to you or your broker. This broker, in turn, will remit corresponding refund amounts to you.

If you receive a refund attributable to reduced withholding taxes under the Income Tax Treaty, you may be required to recognize foreign currency gain or loss, which will be treated as ordinary income or loss to the extent that the dollar value of the refund received or treated as received by you differs from the U.S. dollar equivalent of

100

the refund on the date the dividend on which such withholding taxes were imposed was received or treated as received by you.

TAXATION OF CAPITAL GAINS

Under the Income Tax Treaty, you will not be liable for German tax on capital gains realized or accrued on the sale or other disposition of Bayer AG shares.

Upon a sale or other disposition of Bayer AG shares, you will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference between the amount realized and your adjusted tax basis in the Bayer AG shares. This gain or loss generally will be U.S. source gain or loss, and will be treated as long-term capital gain or loss if your holding period in the Bayer AG shares exceeds one year. The deductibility of capital losses is subject to significant limitations. If you are an individual Qualified Holder of Bayer AG shares, capital gains generally will be subject to tax at preferential rates, provided certain holding periods are met.

PASSIVE FOREIGN INVESTMENT COMPANY STATUS

We believe that we will not be classified as a passive foreign investment company (a "PFIC") for U.S. federal income tax purposes for our current taxable year or any future taxable year. However, as this is a factual matter that must be determined annually at the close of each taxable year, there can be no certainty as to our actual PFIC status in any particular year until the close of the taxable year in question.

GERMAN GIFT AND INHERITANCE TAXES

The Convention between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation with Respect to Taxes on Estates, Inheritances and Gifts, as amended (the "Estate Tax Treaty"), provides that an individual whose domicile is determined to be in the United States for purposes of such treaty will not be subject to German inheritance and gift tax (the equivalent of the U.S. federal estate and gift tax) on the individual's death or making of a gift unless the Bayer AG shares (1) are part of the business property of a permanent establishment located in Germany or (2) are part of the assets of a fixed base of an individual located in Germany and used for the performance of independent personal services. An individual's domicile in the United States, however, does not prevent imposition of German inheritance and gift tax with respect to an heir, donee or other beneficiary who is domiciled in Germany at the time the individual died or the gift was made.

The Estate Tax Treaty also provides a credit against U.S. federal estate and gift tax liability for the amount of inheritance and gift tax paid in Germany, subject to certain limitations, in a case where the shares are subject both to German inheritance or gift tax and U.S. federal estate or gift tax.

GERMAN CAPITAL TAX (VERMOGENSTEUER)

The Income Tax Treaty provides that you will not be subject to German capital tax (Vermogensteuer) with respect to the Bayer AG shares. As a result of a judicial decision, the German capital tax (Vermogensteuer) presently is not imposed.

OTHER GERMAN TAXES

There are no German transfer, stamp or other similar taxes that would apply to you upon receipt, purchase, holding or sale of Bayer AG shares.

U.S. INFORMATION REPORTING AND BACKUP WITHHOLDING

Dividends on Bayer AG shares and payments of the proceeds of a sale of Bayer AG shares paid within the United States or through certain U.S.-related financial intermediaries are subject to information reporting and may be subject to backup withholding at a current rate of up to 30 percent unless you (1) are a corporation or other exempt recipient or (2) provide a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. U.S. persons who are required to establish their exempt status generally must file IRS Form W-9 (Request for Taxpayer Identification Number and Certification). Non-U.S. holders generally

101

will not be subject to U.S. information reporting or backup withholding. However, these holders may be required to provide certification of non-U.S. status (generally on IRS Form W-8BEN) in connection with payments received in the United States or through certain U.S.-related financial intermediaries.

Backup withholdings is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability. You may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK

The global nature of our business exposes our operations, financial results and cash flows to a number of risks, including those listed below.

- Currency exchange rate fluctuations. We are exposed to fluctuations between the euro and other major world currencies. The majority of our currency fluctuation risk is between the euro and the U.S. dollar. In addition, we are exposed to fluctuations between the euro and the Japanese Yen and fluctuations between the euro and the British pound.

- Interest rate fluctuations. We are exposed to changes in interest rates. Our primary interest rate exposure is to fluctuations in short-term U.S. interest rates, especially commercial paper market rates.

- Credit risk. We are exposed to credit risk with respect to the counterparties in our transactions, and

- Raw material price fluctuations. We are exposed to possible increases in raw material prices. We may not be able to pass any such increases on to our customers.

Any of these risks could harm our operating results and financial condition. These risks are similar to the risks to which we were exposed in the prior year.

From time to time, we enter into hedging arrangements to mitigate our exposure to currency and interest risks. Because we believe that the limited liquidity of hedges against changes in raw materials prices makes these hedges unreasonably expensive, we have used them in the past only to a limited extent. If increasing liquidity and lower fees render these hedging arrangements less costly, we would consider using them more often.

Our primary tools for hedging risks are over-the-counter derivative instruments, particularly forward foreign exchange contracts, option contracts, interest rate swaps, and interest and principal currency swaps. As a matter of policy, we enter into these transactions only with counterparties of high credit standing. We have established uniform guidelines and internal controls for the use of derivatives. We use these instruments only to hedge risks arising from our business operations and from related investments and financing transactions. We do not use derivatives for trading or other speculative purposes. In 2000, we began to manage foreign currency risks on anticipated or pending transactions.

SENSITIVITY ANALYSIS

The sensitivity analyses included in the risk sections below present the hypothetical loss in pre-tax income, cash flows or fair value of the financial instruments and derivative financial instruments that we held as of December 31, 2001 and 2000, and were subject to changes in foreign exchange rates and interest rates. The range of sensitivities that we chose for these analyses reflects our view of changes reasonably possible over a one-year period.

INTEREST RATE RISK

Interest rate risk is the possibility that the total return of a financial instrument will change due to movements in market rates of interest. This risk primarily affects receivables and payables with maturities of more than one year. Items with these long maturities are not of material significance to our operations, but are relevant to our investments and financial obligations.

We sometimes make loans to employees. Although a small proportion of these loans are interest-free, they generally bear interest at market-oriented, fixed rates. More than three quarters of our loans to employees have terms of over five years. Because their rates are fixed, these loans are exposed to interest rate fluctuation risk. We do not make these loans for financial purposes, however, and therefore do not hedge their interest rate risk.

103

Derivative financial instruments

Derivative financial instruments are our main method of interest rate hedging. We use interest rate swaps to convert a small portion of our floating rate investments into, in effect, fixed rate investments. The derivatives we use to hedge interest rate risk are primarily over-the-counter instruments, particularly forward rate agreements, option and future contracts, interest rate swaps, and interest and principal currency swaps.

The "notional amount" of these derivatives is the total nominal value of the underlying transactions. The "fair value" of these derivatives is their repurchase value, based on quoted prices or determined by standard methods, as of a given closing date. The table below shows the notional amount and fair value of the interest rate derivatives we held as of December 31, 2001 and 2000; the fair values quoted disregard any opposite movements in the values of the underlying transactions.

                                                              NOTIONAL AMOUNT   FAIR VALUE
                                                              ---------------   -----------
                                                                      DECEMBER 31,
                                                              -----------------------------
                                                               2001     2000    2001   2000
                                                              ------   ------   ----   ----
                                                                   (EUROS IN MILLIONS)
Interest rate hedging contracts.............................  4,485    3,495    (60)   (133)

At December 31, 2001, the notional amount of our short-term interest rate hedging contracts (including interest and principal currency swaps) totaled E2.0 billion (2000: E0.3 billion); those maturing after more than one year totaled E2.5 billion (2000: E3.2 billion).

Sensitivity Analysis

An estimated hypothetical negative effect of 100 basis points, or one percent per year, in interest rates would result in an increase in interest cost per year of approximately E45 million (2000: E40 million) based on our debt position at year-end.

CURRENCY RISK

Because we conduct our operations in many currencies, we face a variety of risks associated with fluctuations in the relative values of these currencies. Upon the introduction of the euro on January 1, 1999, however, the relative values between the "legacy" currencies of the EU member states participating in the third stage of European Monetary Union were irrevocably fixed. Although these legacy currencies are scheduled to remain in circulation until July 2002, we no longer face currency-related risks in relation to member currencies of the Euro Zone.

Transaction Risk

We face transaction risk when our businesses generate revenue in one currency but incur costs relating to that revenue in a different currency. Because we enter into foreign exchange transactions for a significant portion of our contracted and forecasted operational foreign exchange exposures, we believe that a significant increase or decrease in the exchange rate of the euro relative to other major world currencies would not, in the short term, materially affect our cash flows. Over time, however, to the extent that we cannot reflect these exchange rate movements in the pricing of our products in local currency, they could harm our cash flows. In general, appreciation of the euro in relation to another currency has an adverse effect on our reported revenues and results, and depreciation of the euro has a positive effect as long as prices remain unchanged.

Translation Risk

Many of the companies of the Bayer Group are located outside the euro zone. Because the euro is our financial reporting currency, we translate the income statements of these subsidiaries into euro for inclusion in our consolidated financial statements. Period-to-period changes in the average exchange rate for a particular country's currency can significantly affect the translation into euro of both revenues and operating income denominated in that currency. Unlike the effect of exchange rate fluctuations on transaction exposure, the effect

104

of exchange rate translation exposure does not affect our local currency cash flows. See Note 38 to the consolidated financial statements.

Outside the euro zone, we hold significant assets, liabilities and operations denominated in local currencies, most importantly the U.S. dollar, the British pound sterling and the Japanese yen. Although we regularly assess and evaluate the long-term currency risk inherent in these investments, we generally undertake foreign exchange transactions addressing this type of risk only when we are considering withdrawal from a specific venture and repatriating the funds that our withdrawal generates. However, we reflect effects from currency fluctuations on the translation of net asset amounts into euro in our equity position.

Derivative financial instruments

To mitigate the impact of currency exchange fluctuations, we regularly assess our exposure to currency risks and hedge a portion of those risks with derivative financial instruments. Our Corporate Treasury department has central responsibility for managing our currency exposures and using currency derivatives.

We relate the maturity dates of hedging contracts to the anticipated cash flows of the Bayer Group. Our policy is to use a mixture of instruments, basing the specific mix at any time on our technical and fundamental analysis of market conditions.

The table below shows the notional amounts and fair values of the currency derivatives we held as of December 31, 2001 and 2000:

                                                             NOTIONAL AMOUNT      FAIR VALUE

                                                                    (EUROS IN MILLIONS)

* Less than E1 million

At December 31, 2001, we estimated that our aggregate annual direct transaction risk from sales and purchases in foreign currencies was approximately E3.4 billion, which consisted primarily of U.S. dollars ($2.3 billion), Japanese yen (Y70 billion) and British pounds sterling (L0.1 billion). For 2002, we do not anticipate a significant change in these levels of risk with respect to our current business operations. However, the businesses that we would acquire upon consummation of the Aventis CropScience transaction could be exposed to higher levels of risk associated with sales and purchases in foreign currencies.

The following table shows the effective exchange rates (including hedging cost and premium) between the euro and the major world currencies with respect to which we contracted hedging transactions, compared with the market average rates for these currencies for 2001 and 2000:

Sensitivity Analysis

Applying a hypothetical adverse change of 10 percent in foreign currency exchange rates, we estimate the hypothetical loss in cash flows of derivative and non-derivative financial instruments and foreign currency denominated balance sheet positions at December 31, 2001 to be approximately E50 million (2000: 120 million).

CREDIT RISK

Credit risk is the possibility that the value of our assets may become impaired if counterparties cannot meet their obligations in transactions involving financial instruments. Since we do not conclude master netting arrangements with our customers, the total of the amounts recognized in assets represents our maximum exposure to credit risk.

RAW MATERIALS AND COMMODITY PRICE RISKS

We operate in markets in which economic cyclicality often affects raw material and product prices. Fluctuations in prices of raw materials and commodities affect some of our businesses. In order to secure our supply of raw materials, we are party to long-term supply contracts, buying additional quantities on the spot markets as needed. The most important of our raw materials affected by price fluctuations are:

1.3-butadiene  ACN              Benzene  Cyclohexane
Phenol         Propylene oxide  Styrene  Toluene

These products are derived from crude oil, therefore their prices are affected by the market price of crude oil.

We typically use the following measures to avoid and manage pricing risk in purchasing raw materials:

- Coverage of recurrent requirements with long-term contracts to reduce the price volatility of purchases on the spot markets.

- Incorporating pricing formulas linked to economic indices and pre-products into our contracts, rather than using published prices.

We did not hold any significant market risk sensitive commodity instruments at December 31, 2001.

(1) Bayer AG guarantees the principal amount and interest payments of the debt securities issued by Bayer Capital Corp. B.V. and Bayer Ltd. described in the table above. Bayer AG and Bayer Corporation have entered into support agreements with respect to the debt securities issued by Bayer Corporation. Under these agreements, Bayer Corporation can obtain funds from Bayer AG to make payments on these securities if unable to make the payments itself.

106

(2) The warrants entitling bondholders to exchange these bonds for shares of Bayer AG expired on August 28, 1997.

(3) At December 31, 2001, these bonds bore interest at 2.1663%. They matured and were paid in April 2002.

(4) This interest rate will be reset after February 15, 2008.

(5) Under our European MTN program, Bayer AG as well as Bayer Corporation, Bayer Capital Corp. B.V. and Bayer Ltd. (Japan) can issue a variety of debt securities in all major currencies.

(6) The figure listed in the table above is the principal amount in euros of securities issued under our European MTN (or EMTN) program outstanding at December 31, 2001. In October 2001, we filed a registration statement with the Luxembourg exchange in connection with the increase of the maximum outstanding principal amount under this program from E2 billion to E8 billion. Under this program, Bayer AG and the three subsidiaries named in Note 5 may issue debt securities in tranches up to a maximum of E8 billion in principal amount outstanding (or its equivalent in other currencies).

On April 10, 2002, we issued two series of debt securities under our EMTN program in total principal amounts of E3 billion and E2 billion. The first series of securities is due April 10, 2007 and bears interest at an annual rate of 5.375 percent. The second series is due April 10, 2012 and bears interest at an annual rate of 6.000 percent. Including these two series, the total principal amount outstanding under our EMTN program is E5.9 billion.

WARRANTS AND RIGHTS

For a description of the option and stock participation plans that we have established for management and employees, see Item 6, Directors, Senior Management and Employees -- Compensation -- Employee Option Plans. There are otherwise no currently outstanding warrants, rights or other securities convertible into or exchangeable for shares of Bayer AG.

OTHER SECURITIES

None.

AMERICAN DEPOSITARY SHARES

Bayer AG, The Bank of New York, as Depositary, and the registered holders of American Depositary Receipts, or ADRs, and the owners of a beneficial interest in book-entry ADRs, will enter into a Deposit Agreement under which the ADSs are to be issued. The following section summarizes the material terms of the Deposit Agreement. The following is only a summary and does not purport to be complete and is subject to and qualified in its entirety by reference to the Deposit Agreement, including the form of ADRs. Terms used in this summary and not otherwise defined will have the meanings provided for in the Deposit Agreement. The following is a summary of the agreement. Because it is a summary, it does not contain all the information that may be important to you. For more complete information, you should read the entire agreement and the ADR. Copies of these documents are available for inspection at the Corporate Trust Office of The Bank of New York, 101 Barclay Street, New York, NY 10286 (temporarily located at One Wall Street, New York, New York 10286).

AMERICAN DEPOSITARY RECEIPTS

The Bank of New York will issue the ADSs. The ownership interest in each share will be represented by one ADS. The shares (or the right to receive shares) will be deposited by Bayer AG with Dresdner Bank AG, its Custodian in Germany. Each ADS will also represent securities, cash or other property deposited with The Bank of New York but not distributed to ADR holders. The Deposit Agreement refers to the deposited shares together with these other securities, cash or property as "deposited securities". The principal executive office of the Depositary is located at One Wall Street, New York, NY 10286.

You may hold ADRs either directly or indirectly through your broker or other financial institution. If you hold ADRs directly, you are an ADR holder. This description assumes you hold your ADRs directly. If you hold the ADRs indirectly, you must rely on the procedures of your broker or other financial institution to assert the

107

rights of ADR holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

Because The Bank of New York will actually hold the shares, you must rely on it to exercise the rights of a shareholder. The obligations of Bayer AG and The Bank of New York are set out in a deposit agreement among Bayer AG, The Bank of New York and you, as an ADR holder. The agreement and the ADRs are generally governed by New York law.

SHARE DIVIDENDS AND OTHER DISTRIBUTIONS

The Bank of New York has agreed to pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of shares your ADRs represent.

Cash. The Bank of New York will convert any cash dividend or other cash distribution Bayer AG pays on the shares into U.S. dollars, if it can do so on a reasonable basis and can transfer the U.S. dollars to the United States. If that is not possible or if any approval from any government is needed and can not be obtained, the agreement allows The Bank of New York to distribute the foreign currency only to those ADR holders to whom it is possible to do so. It will hold the foreign currency it cannot convert for the account of the ADR holders who have not been paid. It will not invest the foreign currency and it will not be liable for the interest.

Before making a distribution, any withholding taxes that must be paid under German law will be deducted. See Item 10, Additional Information -- Taxation -- Taxation of Dividends. The Bank of New York will distribute only whole U.S. dollars and cents and will round fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when The Bank of New York cannot convert the foreign currency, you may lose some or all of the value of the distribution.

Shares. The Bank of New York may distribute new ADRs representing any shares Bayer AG may distribute as a dividend or free distribution, if Bayer AG furnishes it promptly with satisfactory evidence that it is legal to do so. The Bank of New York will only distribute whole ADRs. It will sell shares which would require it to use a fractional ADR and distribute the net proceeds in the same way as it does with cash. If The Bank of New York does not distribute additional ADRs, each ADR will also represent the new shares.

Rights to receive additional shares. If Bayer AG offers holders of its ordinary shares any rights to subscribe for additional shares or any other rights, The Bank of New York may, after consultation to the extent practicable with Bayer AG, make these rights available to you. Bayer AG must first instruct The Bank of New York to do so and furnish it with satisfactory evidence that it is legal to do so. If Bayer AG does not furnish this evidence and/or give these instructions, and The Bank of New York decides it is practical to sell the rights, The Bank of New York will sell the rights and distribute the proceeds, in the same way as it does with cash. The Bank of New York may allow rights that are not distributed or sold to lapse. In that case, you will receive no value for them.

If The Bank of New York makes rights available to you, upon instruction from you, it will exercise the rights and purchase the shares on your behalf. The Bank of New York will then deposit the shares and issue ADSs to you. It will only exercise rights if you pay it the exercise price and any other charges the rights require you to pay.

U.S. securities laws may restrict the sale, deposit, cancellation and transfer of the ADRs issued after exercise of rights. For example, you may not be able to trade the ADRs freely in the United States. In this case, The Bank of New York may issue the ADRs under a separate restricted deposit agreement which will contain the same provisions as the agreement, except for the changes needed to put the restrictions in place.

Other Distributions. The Bank of New York will send to you anything else Bayer AG distributes on deposited securities by any means it thinks is legal and fair, as promptly as practicable and after consultation, to the extent practicable, with Bayer AG. If it cannot make the distribution in that way, The Bank of New York has a choice. It may decide to sell what Bayer AG distributed and distribute the net proceeds in the same way as it does with cash or it may decide to hold what Bayer AG distributed, in which case the ADSs will also represent the newly distributed property.

108

The Bank of New York is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders. Bayer AG has no obligation to register ADRs, shares, rights or other securities under the Securities Act. Bayer AG also has no obligation to take any other action to permit the distribution of ADSs, shares, rights or anything else to ADR holders. This means that you may not receive the distribution Bayer AG makes on its shares or any value for them if it is illegal or impractical for Bayer AG to make them available to you.

DEPOSIT, WITHDRAWAL AND CANCELLATION

The Bank of New York will issue ADRs if you or your broker deposit shares or evidence of rights to receive shares with the Custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, The Bank of New York will register the appropriate number of ADRs in the names you request and will deliver the ADRs at its Corporate Trust Office to the persons you request.

You may turn in your ADRs at The Bank of New York's Corporate Trust Office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, The Bank of New York will deliver (1) the underlying shares to an account designated by you and (2) any other deposited securities underlying the ADR at the office of the Custodian. Or, at your request, risk and expense, The Bank of New York will deliver the deposited securities at its Corporate Trust Office.

VOTING RIGHTS

Upon receipt of notice from Bayer AG, The Bank of New York will notify you of the upcoming vote and arrange to deliver Bayer AG's voting materials to you. The materials will (1) describe the matters to be voted on and (2) explain how you, on a certain date, may instruct The Bank of New York to vote the shares or other deposited securities underlying your ADRs as you direct. For instructions to be valid, The Bank of New York must receive them on or before the date specified. The Bank of New York will try, as far as practical, subject to German law and the provisions of Bayer AG's Articles of Association, to vote or to have its agents vote the shares or other deposited securities as you instruct. The Bank of New York will only vote or attempt to vote as you instruct. However, if The Bank of New York does not receive your voting instructions, it will give a proxy to vote your shares to a designated representative of Bayer AG.

Bayer AG cannot assure you that you will receive the voting materials in time to ensure that you can instruct The Bank of New York to vote your shares. In addition, The Bank of New York and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote and there may be nothing you can do if your shares are not voted as you requested.

109

FEES AND EXPENSES

ADR holders must pay:                                               For:

You will be responsible for any taxes or other governmental charges payable on your ADRs or on the deposited securities underlying your ADRs. The Bank of New York may refuse to transfer your ADRs or allow you to withdraw the deposited securities underlying your ADRs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities underlying your ADRs to pay any taxes owed and you will remain liable for any deficiency. If it sells deposited securities, it will, if appropriate, reduce the number of ADRs to reflect the sale and pay to you any proceeds, or send to you any property, remaining after it has paid the taxes.

RECLASSIFICATIONS, RECAPITALIZATIONS AND MERGERS

If Bayer AG:                                                        Then:

                                                securities.

AMENDMENT AND TERMINATION

Bayer AG may agree with The Bank of New York to amend the agreement and the ADRs without your consent for any reason. If the amendment adds or increases fees or charges, except for taxes and other governmental charges or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses, or prejudices an important right of ADR holders, it will only become effective 30 days after The Bank of New York notifies you of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADR, to agree to the amendment and to be bound by the ADRs and the agreement is amended.

110

The Bank of New York will terminate the agreement at the direction of Bayer AG by mailing notice of termination to registered holders at least 30 days prior to the date fixed for termination in the notice. The Bank of New York may also terminate the agreement if The Bank of New York has told Bayer AG that it would like to resign and Bayer AG has not appointed a new depositary bank within 60 days.

After termination, The Bank of New York and its agents will be required to do only the following under the agreement: (1) collect distributions on the deposited securities and (2) deliver shares and other deposited securities upon cancellation of ADRs. At any time after the expiration of one year after the date of termination, The Bank of New York may sell any remaining deposited securities by public or private sale. After that, The Bank of New York will hold the proceeds of the sale, as well as any other cash it is holding under the agreement for the pro rata benefit of the ADR holders that have not surrendered their ADRs. It will not invest the money and will have no liability for interest. The Bank of New York's only obligations will be to account for the proceeds of the sale and other cash. After termination our only obligations will be with respect to indemnification and to pay certain amounts to The Bank of New York.

LIMITATIONS ON OBLIGATIONS AND LIABILITY TO ADR HOLDERS

The agreement expressly limits Bayer AG's obligations and the obligations of The Bank of New York, and it limits Bayer AG's liability and the liability of The Bank of New York. Bayer AG and The Bank of New York:

- are only obligated to take the actions specifically set forth in the agreement without negligence or bad faith;

- are not liable if either is prevented or delayed by law or circumstances beyond their control from performing their obligations under the agreement;

- are not liable if either exercises discretion permitted under the agreement;

- have no obligation to become involved in a lawsuit or other proceeding related to the ADRs or the agreement on your behalf or on behalf of any other party; and

- may rely upon any documents they believe in good faith to be genuine and to have been signed or presented by the proper party.

In the agreement, Bayer AG and The Bank of New York agree to indemnify each other under certain circumstances.

REQUIREMENTS FOR DEPOSITARY ACTIONS

Before The Bank of New York will issue or register transfer of an ADR, make a distribution on an ADR, or withdrawal of shares, The Bank of New York may require:

- payment of stock transfer or other taxes or other governmental charges and transfer or registration fees charged by third parties for the transfer of any shares or other deposited securities;

- production of satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and

- compliance with regulations it may establish, from time to time, consistent with the agreement, including presentation of transfer documents.

The Bank of New York may refuse to deliver, transfer, or register transfers of ADRs generally when the books of The Bank of New York or Bayer AG are closed, or at any time if The Bank of New York or Bayer AG thinks it advisable to do so.

You have the right to cancel your ADRs and withdraw the underlying shares at any time except:

- when temporary delays arise due to closing of the transfer books of The Bank of New York or Bayer AG or the deposit of Shares in connection with voting at a shareholders' meeting, or the payment of dividends;

111

- when you or other ADR holders seeking to withdraw shares owe money to pay fees, taxes and similar charges; or

- when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADRs or to the withdrawal of shares or other deposited securities.

This right of withdrawal may not be limited by any other provision of the agreement.

PRE-RELEASE OF ADRS

In certain circumstances, subject to the provisions of the agreement, The Bank of New York may issue ADRs before deposit of the underlying shares. This is called a pre-release of the ADR. The Bank of New York may also deliver shares upon cancellation of pre-released ADRs (even if the ADRs are cancelled before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying shares are delivered to The Bank of New York. The Bank of New York may receive ADRs instead of shares to close out a pre-release. The Bank of New York may pre-release ADRs only under the following conditions: (1) before or at the time of the pre-release, the person to whom the pre-release is being made must represent to The Bank of New York in writing that it or its customer owns the shares or ADRs to be deposited; (2) the pre-release must be fully collateralized with cash or other collateral that The Bank of New York considers appropriate; and (3) The Bank of New York must be able to close out the pre-release on not more than five business days' notice. In addition, The Bank of New York will limit the number of ADRs that may be outstanding at any time as a result of pre-release, although The Bank of New York may disregard the limit from time to time, if it thinks it is appropriate to do so.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors
and Stockholders of Bayer AG

We have audited the accompanying consolidated balance sheet of Bayer AG and its subsidiaries (the "Group") as of December 31, 2001 and 2000, and the related consolidated statements of income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2001. These financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with International Standards on Auditing and auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Bayer AG at December 31, 2001, and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001 in conformity with International Accounting Standards.

International Accounting Standards vary in certain significant respects from accounting principles generally accepted in the United States. The application of the latter would have affected the determination of consolidated net income for the years ended December 31, 2001, 2000 and 1999, and the determination of consolidated stockholders' equity as of December 31, 2001 and 2000, to the extent summarized in Note 44 to the consolidated financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP

ACCOUNTING POLICIES

The consolidated financial statements of the Bayer Group are prepared -- pursuant to Article 292a of the German Commercial Code -- in accordance with the rules of the International Accounting Standards Board (IASB), London, in effect at the closing date. They comply with the European Union's guidelines on consolidation of financial statements (Directive 83/349/EEC).

The financial statements of the consolidated companies are prepared according to uniform recognition and valuation principles. Valuation adjustments made for tax reasons are not reflected in the Group statements. The individual companies' statements are prepared as of the closing date for the Group statements.

In compliance with IAS 37, provisions are established for contingent liabilities if available information indicates that an asset has been impaired or a liability has been incurred, and the amount of the impairment loss can be estimated with sufficient reliability.

Certain income statement and balance sheet items are combined for the sake of clarity, as explained in the Notes. A distinction is made in the balance sheet between long-term and short-term liabilities in accordance with IAS 1 (Presentation of Financial Statements). Liabilities are stated as short-term if they mature within one year. Income received such as royalties, rental income, interest income or dividend income is recognized on an accrual basis.

Changes in recognition and valuation principles are explained in the Notes. The previous year's figures are restated accordingly. Accounting policies for individual categories of items in the income statement and balance sheet are included in the relevant notes.

In a few instances, estimates and assumptions have to be made. These affect the classification and valuation of assets, liabilities, income, expenses and contingent liabilities. The actual values may vary from the estimates.

EFFECTS OF NEW ACCOUNTING PRONOUNCEMENTS

The consolidated financial statements of the Bayer Group for the 2001 fiscal year comply with the following new or revised International Accounting Standards (IAS) and interpretations of the Standing Interpretations Committee (SIC) that the Group implemented for the first time in 2001:

IAS 12 (Revised 2000)        Income Taxes

IAS 19 (Revised 2000)        Employee Benefits

IAS 39                       Financial Instruments: Recognition and Measurement

IAS 40                       Investment Property

SIC-17                       Equity -- Cost of an Equity Transaction

SIC-19                       Reporting Currency -- Measurement and Presentation
                             of Financial Statements under IAS 21 and IAS 29

The adoption of these standards did not have any significant impact on Bayer's financial position or its results of operations during 2001 or on the comparability of its 2001 and 2000 consolidated financial statements.

The following new interpretations will be implemented in 2002. Those applicable for the first time as of December 31, 2001 (marked *) did not have any effect on the 2001 financial statements.

SIC-27                       Evaluating the Substance of Transactions Involving
                             the Legal Form of a Lease*

SIC-28                       Business Combinations -- "Date of Exchange" and
                             Fair Value of Equity Instruments*

SIC-29                       Disclosure -- Service Concession Arrangements*
                                       F-7


NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

SIC-30                       Reporting Currency -- Translation from Measurement
                             Currency to Presentation Currency

SIC-31                       Revenue -- Barter Transactions Involving
                             Advertising Services*

SIC-33                       Consolidation and Equity Method -- Potential Voting
                             Rights and Allocation of Ownership Interests

A series of related transactions legally amounting to a lease contract should be accounted for as a single transaction according to SIC-27 (Evaluating the Substance of Transactions Involving the Legal Form of a Lease). This applies particularly in cases where the substance of the transactions cannot be adequately understood without reference to the series of transactions as a whole.

If a company pays for an acquisition with its own shares, determination of the "date of exchange" is crucial to valuation. According to SIC-28 (Business Combinations -- "Date of Exchange" and Fair Value of Equity Instruments), the "date of exchange" is the day on which the agreed transaction is executed and the acquirer gains control over the net assets and business activities of the acquired unit. The cost of acquisition is based on the publicly quoted price of the equity instruments on that day.

The disclosure requirements for agreements under which the reporting enterprise is granted a concession to provide public services such as drinking water supplies are defined in SIC-29 (Disclosure -- Service Concession Arrangements). All aspects of such concession arrangements should be disclosed.

Where a company's financial statements are published in a currency other than the measurement currency, SIC-30 (Reporting Currency -- Translation from Measurement Currency to Presentation Currency) provides that the statements be translated by the method specified in IAS 21 for foreign companies whose activities are not an integral part of those of the reporting enterprise ("foreign entities").

Rules for realizing revenues from advertising-related barter transactions are given in SIC-31 (Revenue -- Barter Transactions Involving Advertising Services).

According to SIC-33 (Consolidation and Equity Method -- Potential Voting Rights and Allocation of Ownership Interests), potential voting rights that currently can be exercised without restriction, such as those conferred by stock subscription rights or stock purchase options, must be taken into account in determining whether one company controls or significantly influences another. However, the actual ownership interests held must continue to be used for the consolidation.

The adoption of these new interpretations is not expected to have a material effect on Bayer's financial statements.

COMPANIES CONSOLIDATED

The financial statements of the Bayer Group as of December 31, 2001 include Bayer AG and 49 German and 189 foreign consolidated subsidiaries in which Bayer AG, directly or indirectly, has a majority of the voting rights. The total number of consolidated companies has risen by 10 from the previous year. Excluded from consolidation are 85 subsidiaries that in aggregate are immaterial to the net worth, financial position and earnings of the Bayer Group; they account for less than 1 percent of Group sales.

We have included 12 joint ventures -- 29 fewer in total than in the previous year -- by proportionate consolidation in compliance with IAS 31 (Financial Reporting of Interests in Joint Ventures). The decline in the number of included joint ventures is due mainly to the inclusion of DyStar GmbH, Frankfurt am Main, Germany,

by the equity method starting in 2001. The effect of joint ventures on the Group balance sheet and income statement is as follows:

While 11 companies are stated at equity, 58 companies that in aggregate are of minor importance are stated at their carrying amounts.

Consolidated for the first time are 27 companies, including those that belonged to the Cleveland, Ohio-based CSM group, which we acquired at the end of 2000. As a consequence of divestitures and mergers the number of consolidated companies was reduced by 47.

ACQUISITIONS/DIVESTITURES

Acquisitions are accounted for by the purchase method. Accordingly, the results of operations of the acquired businesses are included in the consolidated financial statements as of the respective dates of acquisition. The purchase prices of the foreign acquisitions are translated at the exchange rates in effect at the respective dates of acquisition.

In 2001 a total of E514 million was spent on acquisitions, which were paid for in cash, not with shares of the company. These acquisitions led to goodwill of E50 million, including E45 million in additional goodwill resulting from the Lyondell polyols acquisition. The goodwill amounts are being amortized by the straight-line method over periods not exceeding 20 years.

In June 2001, Bayer Corporation, United States, acquired at a cost of E116 million development, manufacturing and distribution rights for products to detect antibodies to the hepatitis C virus (HCV) and HIV from the strategic cooperation between Ortho-Clinical Diagnostics Inc., Raritan, New Jersey, and Chiron Corporation, Emeryville, California. This acquisition expands the Diagnostics Business Group's portfolio of immunodiagnostic agents, strengthening its laboratory testing segment. The rights are being amortized over an estimated useful life of 12 years.

Bayer expanded its crop protection business in Europe on February 1, 2001 by acquiring MIKADO(R), a leading corn herbicide, from Syngenta AG, Basel, Switzerland, for E115 million. The transaction covers business in the European Union and EFTA (European Free Trade Association) countries as well as patents, registrations, trademark rights, and production and formulation expertise. The acquired intangible assets are being amortized over an estimated useful life of 10 years.

Bayer AG has purchased a E93 million equity interest in CuraGen Corporation, New Haven, Connecticut, a leading biotech company. The objective of the collaboration agreement concluded with CuraGen in mid-January 2001 is to jointly develop and market novel drugs to treat obesity and diabetes. The intention is also to use special genomics-based technologies to evaluate substances in Bayer's early pharmaceutical research pipeline regarding their suitability for further clinical development.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

On May 1, 2001, Bayer Corporation, United States, increased its equity ownership in PharmaNetics Inc., Raleigh, North Carolina, by a further E25 million for the Diagnostics Business Group. The existing distribution agreement with PharmaNetics was expanded to cover Theranostic tests (rapid diagnostic testing during drug therapy), a core component of the technology platform offered by PharmaNetics Inc. The agreement includes non-exclusive rights in the U.S. and exclusive rights elsewhere for the Diagnostics Business Group to distribute Theranostic tests.

In February 2001, Bayer acquired a E17 million equity interest in PPL Therapeutics plc, Edinburgh, United Kingdom. PPL Therapeutics is a biotech company involved in the discovery, development, production and marketing of genetically modified proteins for therapeutic purposes and food products. The Pharmaceuticals Business Group and PPL Therapeutics have concluded an agreement under which Bayer will pursue the clinical development of, and acquire, global exclusive marketing rights to the company's major product, rAAT (recombinant alpha-1-antitrypsin). PPL Therapeutics intends to manufacture the product in a new facility currently scheduled for construction.

On February 12, 2001, the Pharmaceuticals Business Group purchased a E16 million equity interest in Avigen Inc., Alameda, California, a leading biotech company. The investment gives Bayer global, exclusive marketing and distribution rights to the gene therapy Coagulin-B(TM) developed by Avigen Inc. for the treatment of hemophilia B by gene transfer. Avigen Inc. intends to meet global demand for Coagulin-B(TM) from manufacture in a new production facility scheduled for construction.

On March 15, 2001, Bayer Corporation concluded an agreement on HIV and hepatitis C virus (HCV) tests with the biotech company Innogenetics N.V., Ghent, Belgium, for the Diagnostics Business Group. For E12 million Bayer acquired exclusive worldwide distribution and marketing rights, including rights to further developments in the future, for the HIV and HCV product lines manufactured by Innogenetics. These intangible assets are being amortized over an estimated useful life of 10 years.

H.C. Starck GmbH, Goslar, Germany, a subsidiary of Bayer AG, acquired TeCe Technical Ceramics GmbH & Co. KG, Selb, Germany from Deutsche Shell GmbH for E9 million effective January 1, 2001. The acquisition complements H.C. Starck's activities in surface technology and ceramics. The very good manufacturing conditions and geographical advantages support H.C. Starck's aim of expanding its position in the U.S. market. The acquired goodwill of E4 million is being amortized in the Bayer Group financial statements over an estimated useful life of 5 years.

In December 2001, the Consumer Care Business Group of Bayer's Mexican subsidiary Bayer de Mexico, S.A. de C.V. purchased the marketing rights to Cevalin(R), a leading vitamin C brand, and the well-known disinfectant Merthiolate(R) from Eli Lilly. The rights will be amortized over an estimated useful life of 10 years.

Significant DIVESTITURES in 2001 were as follows:

Bayer sold its 50 percent interest in EC Erdolchemie GmbH, Cologne, Germany to the other joint venture partner Deutsche BP AG, Hamburg, Germany, effective May 1, 2001, following approval from the E.U. Commission. The proceeds of the sale amounted to E476 million. Future raw material supplies from Erdolchemie to Bayer are contractually assured, as is the provision of services by Bayer to Erdolchemie.

Bayer Group company Wolff Walsrode AG sold its subsidiary Covexx Films, Walsrode, Germany, a company specializing in high-performance films, to Wipak, part of the Wihuri group of Finland, effective June 1, 2001.

Effective April 1, 2001, Bayer AG sold the H-acid production facilities on its Brunsbuttel site to Rutgers Elbechemie GmbH, a subsidiary of Rutgers VTF AG. Bayer sold its interest in ChemDesign Corporation, Fitchburg, Massachusetts, to Chestnut Acquisition Corporation, Mendham, New Jersey, a subsidiary of Chestnut Investments LLC, Mendham, New Jersey, effective November 30, 2001. ChemDesign manufactures organic chemicals mainly for the agrochemical and photographic industries.

FOREIGN CURRENCY TRANSLATION

The financial statements for 2001 are drawn up in euros (E).

In the financial statements of the individual consolidated companies, foreign currency receivables and payables are translated at closing rates, irrespective of whether they are exchange-hedged. Forward contracts that, from an economic point of view, serve as a hedge against fluctuations in exchange rates are stated at fair value.

The majority of foreign consolidated companies are to be regarded as foreign entities since they are financially, economically and organizationally autonomous. Their functional currencies according to IAS 21 (The Effects of Changes in Foreign Exchange Rates) are thus the respective local currencies. The assets and liabilities of these companies are therefore translated at closing rates, income and expense items at average rates for the year. Goodwill as well as any fair value adjustments arising on the acquisition of entities located outside the European Monetary Union are treated as assets and liabilities of such entities and translated at closing rates.

Where the operations of a foreign company are integral to those of Bayer AG, the functional currency is the euro. Property, plant and equipment, intangible assets, investments in affiliated companies and other securities included in investments are translated at the historical exchange rate on the date of addition, along with any relevant amortization, depreciation and write-downs. All other balance sheet items are translated at closing rates.

F-12

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

Income and expense items (except amortization, depreciation and write-downs) are translated at average rates for the year.

Exchange differences arising from the translation of foreign companies' balance sheets are shown in a separate stockholders' equity item. In case of divestiture, the respective exchange differences are reversed and recognized in income.

The exchange rates for major currencies against the euro varied as follows:

                                                 CLOSING RATE               AVERAGE RATE

CONSOLIDATION METHODS

Capital consolidation is performed according to IAS 22 (Business Combinations) by offsetting investments in subsidiaries against the underlying equities at the dates of acquisition. The identifiable assets and liabilities of subsidiaries and joint ventures are included at their fair values in proportion to Bayer's interest. Remaining differences are recognized as goodwill.

Where the statements of individual consolidated companies reflect write-downs or write-backs of investments in other consolidated companies, these are reversed for the Group statements.

Intragroup sales, profits, losses, income, expenses, receivables and payables are eliminated.

Deferred taxes are recognized for temporary differences related to consolidation entries.

Joint ventures are included by proportionate consolidation according to the same principles.

The consolidated financial statements include the accounts of those material subsidiaries in which Bayer AG is able to exercise operational control, generally through an ownership interest greater than 50 percent.

The equity method is used to account for investments in material entities in which Bayer AG exerts significant influence, generally through an ownership interest between 20 and 50 percent.

Intercompany profits and losses on transactions with companies included at equity were immaterial in 2001, 2000 and 1999.

CASH FLOW STATEMENT

The cash flow statement shows how the liquidity of the Bayer group was affected by the inflow and outflow of cash and cash equivalents during the year. The effects of acquisitions, divestitures and other changes in the scope of consolidation are eliminated. Cash flows are classified by operating, investing and financing activities in accordance with IAS 7 (Cash Flow Statements). An adjustment is shown to reconcile cash and cash equivalents at the end of the year to the liquid assets reflected in the balance sheet.

The amounts reported by foreign consolidated companies are translated at average exchange rates for the year, with the exception of cash and cash equivalents, which are translated at closing rates as in the balance sheet. The effect of changes in exchange rates on cash and cash equivalents is shown separately.

NOTES TO THE STATEMENTS OF INCOME

[1] NET SALES

Sales are recognized upon delivery of goods or rendering of services to third parties and are reported net of sales taxes and rebates. Revenues from contracts that contain customer acceptance provisions are deferred until customer acceptance occurs or the contractual acceptance period has lapsed. Allocations to provisions for rebates to customers are recognized in the period in which the related sales are recorded based on the contract terms. Payments relating to the sale or outlicensing of technologies or technological expertise -- once the respective agreements have become effective -- are immediately recognized in income if all rights to the technologies and all obligations resulting from them have been relinquished under the contract terms. However, if rights to the technologies continue to exist or obligations resulting from them have yet to be fulfilled, the payments received are recorded in line with the actual circumstances.

While total reported sales declined 2001 by E0.7 billion, to E30.3 billion (2000: E31.0 billion; 1999: E27.3 billion), sales from continuing operations increased by E0.3 billion to E28.9 billion (2000: E28.6 billion; 1999: E23.6 billion). In 2001, a E0.9 billion decrease due to lower volumes was offset by positive contributions of E0.3 billion from higher selling prices, E0.1 billion from favorable shifts in exchange rates and E0.8 billion from the net effect of acquisitions and divestitures. Acquisitions and divestitures during 2001 and 2000 affected the comparison between the two years' sales figures by the following amounts:

2000 sales increased by E3.7 billion compared with 1999, to E31.0 billion. Sales from continuing operations advanced by E5.0 billion, to E28.6 billion. The increase in 2000 comprised E1.6 billion from higher volumes, E0.5 billion from improvement in selling prices, E2.2 billion from favorable shifts in exchange rates and E0.7 billion from the net positive effect of acquisitions and investitures. Acquisition and divestitures during 2000 and 1999 affected the comparison between the two years-sales figures by the following amounts:

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

[2] SELLING EXPENSES

Selling expenses include E782 million (2000: E776 million; 1999: E609 million) in shipping and handling costs.

They also include advertising and promotion costs, expensed in the period in which they are incurred. These costs amount to E1,389 million (2000: E1,331 million; 1999: E1,083 million).

[3] RESEARCH AND DEVELOPMENT EXPENSES

According to IAS 38 (Intangible Assets), research costs cannot be capitalized; development costs can only be capitalized if specific conditions are fulfilled. Development costs must be capitalized if it is sufficiently certain that the future economic benefits to the company will cover not only the usual production, selling and administrative costs but also the development costs themselves. There are also several other criteria relating to the development project and the product or process being developed, all of which have to be met to justify asset recognition. As in previous years, these conditions are not satisfied.

[4] OTHER OPERATING INCOME

Among the items of other operating income from continuing operations for 2001 are E68 million (2000: E83 million; 1999: E117) from reversals of unutilized provisions, E74 million (2000: E74 million; 1999: E15 million) from retirements of noncurrent assets, and E25 million (2000: E25 million; 1999: E34 million) from sideline operations.

The cost of goods sold incurred for sideline operations has been offset against the corresponding revenues to more clearly reflect the earnings position. Also included here is E45 million in income resulting from an agreement concluded with Syngenta to settle a patent dispute over thiomethoxam.

[5] OTHER OPERATING EXPENSES

Included in other operating expenses for continuing operations in 2001 are E90 million (2000: E35 million; 1999: E52 million) in write-downs of receivables, E94 million (2000: E77 million; 1999: E139 million) in amortization of acquired goodwill and E15 million (2000: E25 million; 1999: E53 million) in losses from the sale of property, plant and equipment.

In addition, E214 million (2000: E200 million; 1999: E449 million) was spent on restructuring. Further details of restructuring expenses are given in Note 29.

[6] DISCONTINUING OPERATIONS

Bayer sold its 50 percent interest in EC Erdolchemie GmbH, Cologne, to the joint venture partner Deutsche BP AG, Hamburg, effective May 1, 2001. The operating result of Erdolchemie for 2001 shown in the following table comprises the result of the business group's operations up to the date of divestiture and the income from the sale of the 50 percent interest.

In April 2001 Bayer decided to divest the remaining activities of its Fibers Business Group, including the production facilities for Dorlastan(R) spandex fibers and Perlon(R) monofilaments.

In the course of its reorganization Bayer plans to divest the Haarmann & Reimer business group, whose activities it now regards as non-core. It is therefore intended to sell the wholly owned subsidiary Haarmann & Reimer GmbH, a manufacturer of fragrances and flavors based in Holzminden, Germany.

The non-operating results and the income taxes attributable to Haarmann & Reimer, Fibers, Erdolchemie, DyStar and Agfa are reflected in the corresponding items of the income statement.

[7] OPERATING RESULT

In accordance with IAS 14 (Segment Reporting), a breakdown of certain data in the financial statements is given by segment and geographical region. The segments and regions are the same as those used for internal reporting. The aim is to provide users of the financial statements with information regarding the profitability and future prospects of the Group's various activities. To allow a more accurate appraisal of continuing operations, the discontinuing operations are shown separately.

The Bayer Group is managed on the basis of business groups, which are aggregated into reportable segments according to economic characteristics, products, production processes, customer relationships and methods of distribution. There are currently 14 business groups, which are aggregated here into 7 reportable segments.

The reconciliation line reflects intersegment items and income and expenses not allocable to the segments, such as central R&D expenses, corporate costs, and revenues and expenses from sideline operations. The intersegment sales reflect intragroup transactions effected at transfer prices fixed on an arm's-length basis. The reconciliation line also reflects those assets and liabilities that cannot be allocated to the reportable segments.

Business activities which Bayer has already divested or intends to divest are shown as discontinuing operations. These are the worldwide DyStar business group; the Erdolchemie business group located in Europe, the worldwide Agfa business segment, the worldwide Fibers business and the worldwide Haarmann & Reimer business.

The business segment and regional data are calculated as follows:

- The intersegment and interregional sales reflect intragroup transactions effected at transfer prices fixed on an arm's-length basis.

- The other operating income comprises that reflected in the income statement, including such income from discontinuing operations.

- Comparability of the operating results of different years may be restricted by exceptional items relating particularly to restructuring measures and acquisitions or divestitures of companies or businesses. For this reason the operating result before exceptional items is shown in addition.

- The return on sales before exceptional items is the ratio of the operating result before exceptional items to external sales.

- Expenses included in exceptional items mainly relate to restructuring measures affecting the operating business.

[11] INCOME TAXES

This item comprises the income taxes paid or accrued in the individual countries, plus deferred taxes. Deferred taxes arise from temporary differences between the carrying amounts of assets or liabilities in the accounting and tax balance sheets, from consolidation measures and from realizable loss carryforwards. Deferred taxes are calculated at the rates which -- on the basis of the statutory regulations in force, or already enacted in relation to future periods, as of the closing date -- are expected to apply in the individual countries at the time of realization.

The breakdown of pre-tax income and income tax expense by origin is as follows:

                                                              2001     2000     1999

A valuation allowance is recognized against tax loss carryforwards when it is not sufficiently certain that this income will be realized.

Changes in tax rates diminished deferred tax expense for 2001 by E8 million (2000: E21 million; 1999: E41 million increase).

Deferred taxes -- computed according to IAS 12 (Income Taxes) -- result primarily from temporary differences between the accounting and tax balance sheets of the individual consolidated companies with regard to the recognition and/or valuation of certain items.

* According to IAS 12 (Income Taxes), deferred tax assets and deferred tax liabilities should, under certain conditions, be offset if they relate to income taxes levied by the same taxation authority.

In 2001, deferred tax assets of E9 million and deferred tax liabilities of E10 million relate to changes in the scope of consolidation. Utilization of tax loss carryforwards from previous years diminished the amount of income taxes paid or accrued in 2001 by E88 million (2000: E7 million; 1999: E9 million).

The value of existing loss carryforwards by expiration date is as follows:

Deferred tax assets of E204 million (2000: E15 million; 1999: E9 million) are recognized on the E540 million (2000: E48 million; 1999: E27 million) of loss carryforwards that represent income likely to be realized in the future. Recognition of these deferred tax assets results in deferred tax income of E198 million.

Deferred tax liabilities have not been recognized for temporary differences associated with investments in foreign subsidiaries of E3,030 million (2000:
E2,887 million, 1999: E2,617 million) as Bayer has determined that the profits concerned will not be distributed in the foreseeable future. If deferred taxes were recognized for these temporary differences, the liability would be based on the respective withholding tax rates only. For most countries, double taxation agreements ensure that any withholding taxes paid can be deducted from the tax base or the tax to be paid in Germany.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

The actual income tax expense for 2001 of E154 million (2000: E1,148 million, 1999: E818 million) is E259 million (2000: E31 million, 1999: E394 million) less than the E413 million (2000: E1,179 million, 1999: E1,212 million) that would result from applying to the pre-tax income of the Group a tax rate of 37.1 percent (2000: 39.5 percent, 1999: 42.7 percent), which is the weighted average of the theoretical tax rates for the individual Group companies.

The reconciliation of theoretical to actual income tax expense for the Group is as follows:

[12] OTHER TAXES

Other taxes amounting to E247 million (2000: E229 million; 1999: E189 million) are included in the cost of goods sold, selling expenses, research and development expenses or general administration expenses. These are mainly property-related taxes.

[13] MINORITY STOCKHOLDERS' INTEREST

Minority interest in income amounts to E6 million (2000: E29 million; 1999:
E16 million), and minority interest in losses to E10 million (2000: E3 million; 1999: E0 million), adding E4 million to (2000: subtracting E26 million from; 1999: subtracting E16 million from) income after taxes.

[14] EARNINGS PER SHARE

Earnings per share are determined according to IAS 33 (Earnings Per Share) by dividing the net income by the average number of shares.

In 2001, in 2000 and in 1999 the number of shares remained constant at 730,341,920. Earnings per share were E1.32 (2000: E2.49; 1999: E2.74).

There were no subscription rights outstanding in 2001, in 2000 or in 1999, and therefore no dilutive potential shares.

[15] COST OF MATERIALS

The total cost of materials for continuing operations amounted to E11,057 million (2000: E10,040 million; 1999: E7,041 million), comprising E10,361 million (2000: E9,380 million; 1999: E6,495 million) in expenses for raw materials, supplies and goods purchased for resale, and E696 million (2000: E660 million; 1999: E546 million) in expenses for purchased services.

The cost of materials for the discontinuing operations was E533 million (2000: E1,168 million; 1999: E2,101 million). While Erdolchemie incurred costs of E153 million (2000: E545 million; 1999: E371 million) entirely for raw materials and supplies, Haarmann & Reimer accounted for E344 million (2000: E393 million; 1999: E333 million), including E10 million (2000: E10 million; 1999: E4 million) for purchased services.

The employees of joint ventures are included in the above figures in proportion to Bayer's interests in the respective companies. The total number of people employed by our joint ventures in 2001 was 1,075 (2000: 1,048; 1999:
1,121).

The figures in the above table do not include people employed in discontinuing operations. In 2001, Haarmann & Reimer employed on average 3,660 people (2000: 3,742; 1999: 3,882); Fibers employed on average 1,169 people (2000: 1,643; 1999: 1,645).

[18] INTANGIBLE ASSETS

Acquired intangible assets other than goodwill are recognized at cost and amortized by the straight-line method over a period of 4 to 15 years, depending on their estimated useful lives. Write-downs are made for impairment losses. Assets are written back if the reasons for previous years' write-downs no longer apply.

Goodwill, including that resulting from capital consolidation, is capitalized in accordance with IAS 22 and amortized on a straight-line basis over a maximum estimated useful life of 20 years. The value of goodwill is reassessed regularly based on impairment indicators and written down if necessary. In compliance with IAS 36 (Impairment of Assets), such write-downs of goodwill are measured by comparison to the discounted cash flows expected to be generated by the assets to which the goodwill can be ascribed.

Self-created intangible assets are not capitalized.

The exchange differences are the differences between the carrying amounts at the beginning and the end of the year that result from translating foreign companies' figures at the respective different exchange rates and changes in their assets during the year at the average rate for the year.

[19] PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is carried at the cost of acquisition or construction. Assets subject to depletion are depreciated over their estimated useful lives. Writedowns are made for any declines in value that go beyond the depletion reflected in depreciation. In compliance with IAS 36 (Impairment of Assets), such write-downs are measured by comparing the carrying amounts to the discounted cash flows expected to be generated by the respective assets. Where it is not possible to estimate the impairment loss for an individual asset, the loss is assessed on the basis of the discounted cash flow for the cash-generating unit to which the asset belongs. Assets are written back if the reasons for previous years' write-downs no longer apply.

The cost of construction of self-constructed property, plant and equipment comprises the direct cost of materials, direct manufacturing expenses, appropriate allocations of material and manufacturing overheads, and an appropriate share of the depreciation and write-downs of assets used in construction. It includes the shares of expenses for company pension plans and discretionary employee benefits that are attributable to construction.

F-28

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

If the construction phase of property, plant or equipment extends over a long period, the interest incurred on borrowed capital up to the date of completion is capitalized as part of the cost of acquisition or construction.

Expenses for the repair of property, plant and equipment are normally charged against income, but they are capitalized if they result in an enlargement or substantial improvement of the respective assets.

Property, plant and equipment is depreciated by the straight-line method, except where the declining-balance method is more appropriate in light of the actual utilization pattern.

When assets are retired, sold, or abandoned, the difference between the net proceeds and the net carrying amount of the assets is recognized as a gain or loss in other operating income or expenses, respectively.

The following depreciation periods, based on the estimated useful lives of the respective assets, are applied throughout the Group:

Buildings..................................................  20 to 50 years
Outdoor infrastructure.....................................  10 to 20 years
Plant installations........................................   6 to 20 years
Machinery and apparatus....................................   6 to 12 years
Laboratory and research facilities.........................    3 to 5 years
Storage tanks and pipelines................................  10 to 20 years
Vehicles...................................................    4 to 8 years
Computer equipment.........................................    3 to 5 years
Furniture and fixtures.....................................   4 to 10 years

In accordance with IAS 17 (Leases), assets leased on terms equivalent to financing a purchase by a long-term loan (finance leases) are capitalized at the lower of their fair value or the present value of the minimum lease payments. The leased assets are depreciated over their estimated useful life except where subsequent transfer of title is uncertain, in which case they are depreciated over their estimated useful life or the respective lease term, whichever is shorter. The future lease payments are recorded as financial obligations.

The exchange differences are as defined for intangible assets.

Capitalized property, plant and equipment includes assets with a total net value of E588 million (2000: E199 million) held under finance leases. The gross carrying amounts of these assets total E1,229 million (2000: E277 million). These assets are mainly machinery and technical equipment with a carrying amount of E425 million (gross amount E975 million) and buildings with a carrying amount of E106 million (gross amount E141 million). In the case of buildings, either the present value of the minimum lease payments covers substantially all of the cost of acquisition, or title passes to the lessee on expiration of the lease.

Also included are products leased to other parties under operating leases with a carrying amount of E381 million (2000: E247 million), the gross carrying amount of the assets concerned being E753 million (2000: E717 million). However, if under the relevant agreements the lessee is to be regarded as the economic owner of the assets and the lease therefore constitutes a finance lease as defined in IAS 17 (Leases), a receivable is recognized in the balance sheet in the amount of the discounted future lease payments.

[20] INVESTMENTS

Investments in non-consolidated subsidiaries and other affiliated companies are generally carried individually at cost. Where other affiliated companies or other securities included in investments are classified as held-to-maturity investments or available-for-sale financial assets, they are recognized in compliance with IAS 39 (Financial Instruments: Recognition and Measurement) at amortized cost or fair value. Where evidence exists that

such assets may be impaired, they are written down as necessary on the basis of an impairment test. Investments are written back if the reasons for previous years' write-downs no longer apply.

The cost of acquisition of investments in companies included at equity is adjusted annually in line with any changes in these companies' total stockholders' equity. In the first-time consolidation, differences between the cost of acquisition and the underlying equities at the dates of acquisition of the investments are allocated to assets or liabilities by the same method applied to fully consolidated subsidiaries. Loans receivable that are interest-free or bear low rates of interest are carried at present value; other loans receivable are carried at nominal value.

The exchange differences are as defined for intangible assets.

The additions to investments in associated companies relate mainly to a manufacturing company being established jointly with Lyondell and the first-time inclusion of DyStar GmbH at equity. The difference between the equity interest in the underlying net assets of companies included at equity and their at-equity accounting values is E45 million (2000: E91 million). It relates primarily to goodwill. Since Bayer no longer exerts significant influence over Agfa-Gevaert N.V., Belgium, Bayer's 30 percent interest in this company, which was previously valued at equity, is included at fair value under investments in other companies.

[21] INVENTORIES

Raw materials, supplies, and goods purchased for resale are valued at the cost of acquisition; work in process and finished goods are valued at the cost of production. If the inventory values are lower at the closing date because of a drop in market prices, for example, the lower amounts are shown. Of the E5,818 million (2000: E6,095 million) in inventories carried as of December 31, 2001, E824 million (2000: E431 million) represents those included at their net realizable value.

Inventories are normally valued by the weighted-average method.

The cost of production comprises the direct cost of materials, direct manufacturing expenses, appropriate allocations of material and manufacturing overheads, and an appropriate share of the depreciation and write-downs of assets used for production. It also includes the shares of expenses for company pension plans and discretionary employee benefits that are attributable to production. Administrative costs are included where they are attributable to production.

Work in process and finished goods are grouped together in light of the production sequences characteristic of the chemical industry. Inventories are comprised as follows:

[28] PROVISIONS FOR PENSIONS AND OTHER POST-EMPLOYMENT BENEFITS

Group companies provide retirement benefits for most of their employees, either directly or by contributing to independently administered funds. The way these benefits are provided varies according to the legal, fiscal and economic conditions of each country, the benefits generally being based on the employees' remuneration and years of service. The obligations relate both to existing retirees' pensions and to pension entitlements of future retirees. Group companies provide retirement benefits under defined contribution and/or defined benefit plans.

In the case of DEFINED CONTRIBUTION PLANS, the company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. Once the contributions have been paid, the company has no further payment obligations. The regular contributions constitute net periodic costs for the year in which they are due and as such are included in the cost of goods sold, selling expenses, research and development expenses or general administration expenses, and thus in the operating result. In 2001, these expenses totaled E312 million (2000: E437 million; 1999: E491 million).

All other retirement benefit systems are DEFINED BENEFIT PLANS, which may be either unfunded, i.e. financed by provisions (accruals), or funded, i.e. financed through pension funds. In 2001, expenses for defined benefit plans amounted to E301 million (2000: E326 million; 1999: E359 million). These net periodic costs -- except for the interest portion -- are generally included in the cost of goods sold, selling expenses, research and development expenses, general administration expenses or other operating income. For the most important defined benefit plans they are comprised as follows:

The pension provisions for defined benefit plans are calculated in accordance with IAS 19 (Employee Benefits) by the projected unit credit method. The future benefit obligations are valued by actuarial methods on the basis of an appropriate assessment of the relevant parameters.

Benefits expected to be payable after retirement are spread over each employee's entire period of employment, allowing for future changes in remuneration.

The legally independent fund "Bayer Pensionskasse VvaG" (Bayer Pensionskasse) is a private insurance company and is therefore subject to the German Law on the Supervision of Private Insurance Companies. Since Bayer guarantees the commitments of the Bayer Pensionskasse, it is classified as a defined benefit plan for IAS and U.S. GAAP purposes.

All defined benefit plans necessitate actuarial computations and valuations. These are based not only on life expectancy but also on the following parameters, which vary from country to country according to economic conditions:

The adjustments, as yet unrecognized in the income statement, represent the difference between the defined benefit obligation -- after deducting the fair value of plan assets -- and the net liability recognized in the balance sheet. They arise mainly from actuarial gains or losses caused by differences between actual and previously assumed trends in employee turnover and remuneration. Pension assets in excess of the obligation are reflected in other receivables, subject to the asset limitation specified in IAS 19 (Employee Benefits). In accordance with IAS 19, the amounts reflected in the balance sheet will be recognized in the income statement over the expected average remaining working lives of existing employees. The portion of the net actuarial gain or loss to be recognized in the income statement is determined by the corridor method. The actual return on plan assets was a loss of E606 million for defined benefit plans providing pension and healthcare benefits. The net liability under these defined benefit plans changed as follows:

* less than E1 million

Funds and benefit obligations are valued on a regular basis at least every three years. For all major funds, comprehensive actuarial valuations are performed annually.

Provisions are also set up under this item for the obligations of Group companies, particularly in the United States, to provide health care to their retirees. For health care costs, the valuation is based on the assumption that they will increase at an annual rate of 5 percent in the long term. Early retirement and certain other benefits to retirees are also included, since these obligations are similar in character to pension obligations. Like pension obligations, they are valued in line with international standards. In 2001, provisions for early retirement and other post-retirement benefits amounted to E635 million (2000: E637 million). The resulting expenses for 2001 amounted to E63 million (2000: E214 million), comprising E23 million (2000: E192 million) for service cost, E58 million (2000: E52 million) for interest cost, E31 million (2000: E30 million) for expected return on plan assets and E13 million (2000: E0 million) for actuarial losses.

[29] OTHER PROVISIONS

Other provisions are valued in accordance with IAS 37 (Provisions, Contingent Liabilities and Contingent Assets) and, where appropriate, IAS 19 (Employee Benefits), using the best estimate of the extent of the obligation. Long-term portions of provisions are discounted to their present value. The Group sets up and maintains provisions for probable and on-going litigation cases when a reasonable estimate can be made. These provisions include all estimated legal fees and costs of settlement. The amounts are based upon written notification and reasonable settlement cost estimates provided by the Group's attorneys. Periodically, but at least quarterly, the provisions are reviewed with the Group's attorneys and updated.

The breakdown of provisions is as follows:

STOCK COMPENSATION PROGRAM

Bayer's three-tier stock compensation program was first launched in 2000. It consists of a Stock Option Program for the members of the Board of Management and senior executives, a Stock Incentive Program for middle management and equivalent employees, and a Stock Participation Program for junior management and other employees. To be eligible for the Stock Option Program, Stock Incentive Program or Module 1 of the Stock Participation Program, participants must place Bayer AG shares of their own into a special deposit account. Participants do not pay an exercise price for the shares they receive under these programs. Rather, they receive the

F-37

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

shares as bonus shares or, in the case of Module 2 of the Stock Participation Program, have the opportunity to purchase shares at a discounted price.

Stock Option Program

Members of the Board of Management and senior executives who wish to participate in the Stock Option Program must place Bayer AG shares of their own in a special deposit account. We determine on an individual basis the maximum number of shares each participant may deposit; the participant receives one option right for each 20 shares deposited. These deposited shares are "locked up"; the participant may not sell them during the following three years. After the end of these three years, a two-year exercise period begins. During this period, the participant may exercise the option rights if he or she has fulfilled the performance criteria. Any unexercised option rights expire at the end of this two-year period. To determine whether the participant is eligible to exercise option rights and, if so, the number of shares received upon exercise, we apply three performance criteria. Two of these measure the relative performance of the Bayer AG share; the third measures the individual contribution of the participant. If the participant fails to meet minimum standards under these criteria, he or she receives no shares under the program. At December 31, 2001, no options were exercisable. No options expired, nor were any options cancelled, during fiscal 2001.

If it is not possible to issue shares under the Stock Option Program to participants at the time they are entitled to exercise their option rights, the option rights would function as share appreciation rights. Instead of shares, the participant would receive the cash value of the shares to which the option rights would otherwise entitle him or her, based on the trading price of the Bayer AG share at the time of exercise.

Stock Incentive Program

Like the Stock Option Program, our Stock Incentive Program for middle management requires participants to deposit Bayer AG shares of their own in a special deposit account. Each participant may deposit shares with a maximum aggregate value of half his or her performance-related bonus for the preceding fiscal year. The number of incentive shares the participant receives depends on the number deposited at the launch of the program as well as on the overall performance of Bayer stock. Unlike the Stock Option Program, the Stock Incentive Program does not "lock up" deposited shares. Participants may sell their deposited shares during the term of the program, but any deposited shares they sell are no longer counted in calculating the number of incentive shares for subsequent distribution dates. The Stock Incentive Program has a ten-year term. There are three incentive share distribution dates during this period. On these dates, the participant receives incentive shares as follows:

Issuance of incentive shares to employees in the Stock Incentive Program

                                                       INCENTIVE SHARES RECEIVED

                                                                  ---

Participants receive incentive shares only if Bayer stock has outperformed the Dow Jones EURO STOXX 50 index on the relevant distribution date, as calculated from the beginning of the program.

Stock Participation Program

Our Stock Participation Program has two components, Module 1 and Module 2. Employees not covered by the Stock Option Program or Stock Incentive Program may participate in both Module 1 and Module 2. The Module 1 program, like the Stock Incentive Program, requires participants to deposit Bayer AG shares of their

F-38

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

own in a special account. As with the Stock Incentive Program, participants in the Stock Participation Program may sell their deposited shares during the term of the program; any shares they sell are no longer counted in calculating the number of bonus shares on subsequent distribution dates.

Module 1 has a term of ten years and entitles the participant to receive incentive shares on three distribution dates based on the number of shares he or she has deposited. Unlike the Stock Incentive Program, Module 1 does not impose a share performance criterion. The participant receives incentive shares as follows on the distribution dates:

Issuance of incentive shares to employees in the Stock Participation Program

                                                       INCENTIVE SHARES RECEIVED

                                                                  ---

In addition, under Module 2 each participant may purchase 10 Bayer AG shares per year at a tax-free discount of E15.34 (2000: E15.34) per share to the market price. Participants may not include shares that they purchase under Module 2 among the shares they deposit under Module 1. Each participant may take up both modules up to a maximum aggregate value of half his or her performance-related bonus in the year he or she enters the program.

The Stock Option Program, the Stock Incentive Program and Module 1 of the Stock Participation Program are accounted for as follows: Since participants are entitled to receive shares of Bayer AG stock bought in the capital market, subject to certain performance criteria, compensation expense for potential share distributions is recorded when there is a reasonable basis on which to estimate whether the performance criteria will ultimately be met. Compensation expense is recorded at each balance sheet date by estimating the number of rights outstanding multiplied by the current quoted market price of Bayer AG shares. The related personnel provisions on December 31, 2001 amounted to E12 million.

For Module 2 of the Stock Participation Program, the difference between the quoted market price of Bayer AG stock and the discounted price paid by participants at the date of purchase is expensed immediately. During the year ended December 31, 2001, participants in Module 2 received 252,652 shares at a total price of E7.8 million, resulting in personnel expenses of E3.9 million. The discount to the price of Bayer AG stock was 33.2 percent.

ENVIRONMENTAL PROVISIONS

The Group's activities are subject to extensive laws and regulations in the jurisdictions in which it does business and maintains properties. Our compliance with environmental laws and regulations may require us to remove or mitigate the effects of the disposal or release of chemical substances at various sites. Under some of these laws and regulations, a current or previous owner or operator of property may be held liable for the costs of removal or remediation of hazardous substances on, under, or in its property, without regard to whether the owner or operator knew of, or caused the presence of the contaminants, and regardless of whether the practices that resulted in the contamination were legal at the time they occurred. As many of our production sites have an extended history of industrial use, it is impossible to predict precisely what effect these laws and regulations will have on us in the future.

As is typical for companies involved in the chemical and related industries, soil and groundwater contamination has occurred in the past at some of our sites, and might occur or be discovered at other sites. We are subject to claims brought by United States Federal or State regulatory agencies and other private entities and individuals regarding the remediation of sites that we own, formerly owned or operated, where materials were

F-39

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

produced specifically for us by contract manufacturers or where waste from our operations was treated, stored or disposed. In particular, we have a potential liability under the U.S. Federal Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as "Superfund", the U.S. Resource Conservation and Recovery Act and related state laws for investigation and remediation costs at a number of sites. At most of these sites, numerous companies, including Bayer, have been notified that the U.S. Environmental Protection Agency, state governing body or private individuals consider such companies to be potentially responsible parties under Superfund or related laws. At other sites, Bayer is the sole responsible party. The proceedings relating to these sites are in various stages. In most cases remediation measures have already been initiated.

Provisions for environmental remediation as of December 31, 2001 amounted to E200 million (2000: E230 million). The material components of the provisions for environmental remediation costs primarily relate to land reclamation, rehabilitation of contaminated sites, recultivation of landfills, and redevelopment and water protection measures. The provisions for environmental remediation costs are recorded on a discounted basis where environmental assessments or clean-ups are probable, the costs can be reasonably estimated and no future economic benefit is expected to arise from these measures. The above amount of provisions represents anticipated future remediation payments totaling E265 million (2000: E304 million), discounted at risk-free rates of 0.5 percent to 5.5 percent.

These discounted amounts will be paid out over the period of remediation of the relevant sites, which is expected to be 15 years. Costs are estimated based on significant factors such as previous experience in similar cases, environmental assessments, development of current costs and new circumstances with major influences on expenses, our understanding of current environmental laws and regulations, the number of other potentially responsible parties at each site and the identity and financial position of such parties in light of the joint and several nature of the liability, and the remediation methods expected to be employed.

It is difficult to estimate the future costs of environmental protection and remediation because of many uncertainties, particularly with regard to the status of laws, regulations and the information available about conditions in the various countries and at the individual sites. Subject to these factors, but taking into consideration our experience to date regarding environmental matters of a similar nature, we believe that the provisions are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities in this area, it cannot be guaranteed that additional costs will not be incurred beyond the amounts accrued. It is possible that final resolution of these matters may require us to make expenditures in excess of established provisions, over an extended period of time and in a range of amounts that cannot be reasonably estimated. Management nevertheless believes that such additional amounts, if any, would not have a material adverse effect on the Group's financial position, results of operations or cash flows.

LEGAL RISKS

As a global company with a heterogeneous business portfolio, Bayer is exposed to numerous legal risks, particularly in the areas of product liability, patent disputes, tax assessments, competition and antitrust law, and environmental matters. We cannot predict with certainty the outcome of any proceedings in which we are or may become involved. It is therefore possible that legal judgments give rise to expenses that are not fully covered by insurers' compensation payments and significantly affect our revenues and earnings.

In the opinion of the management, however, currently pending litigation is unlikely to result in judgments that would materially affect the Group's financial position or results of operations.

RESTRUCTURING CHARGES

Charges incurred for restructuring programs during 2001 were E214 million, including E98 million in provisions that are expected to be used as the related actions under the plans are completed. The total charges comprise E57 million in severance payments, E61 million in accelerated amortization/depreciation and write-downs of intangible assets, property, plant and equipment, and E96 million in other expenses.

F-40

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

Of the restructuring charges in 2001, a total of E39 million is related to the integration of the polyols business acquired from Lyondell, with severance payments accounting for E13 million, other expenses for E19 million and asset write-downs for E7 million. The greater part of the severance payments and other expenses for 2001 will lead to disbursements in 2002.

The restructuring of our styrenics business in North America and Europe led to a further E43 million in charges, including E19 million for write-downs and E24 million for other expenses.

In the second half of 2001 we announced plans to restructure our styrenics operations in Camacari, Brazil, resulting in charges of E22 million, comprising E16 million in write-offs of assets no longer utilized and E6 million in other expenses.

In 2001, a further E15 million in restructuring charges was incurred in the U.S. for the restructuring of the Consumer Care Business Group in Elkhart, Indiana, including E9 million in write-downs and E6 million in other expenses.

In the second half of 2001 we initiated restructuring measures to enhance the efficiency of our U.S. production facilities in Baytown, Texas and New Martinsville, West Virginia. The E35 million in charges comprises E21 million in severance payments and E13 million in other expenses. We also announced plans to close down a facility in West Virginia, resulting in E10 million in write-offs of assets no longer utilized and E3 million in severance payments.

The ongoing restructuring programs to improve profitability in the Pharmaceuticals Business Group gave rise to E26 million in charges, comprising E7 million in severance payments and E19 million in other expenses.

Further charges relate to various small-scale restructuring programs. Changes in provisions and expenses for restructuring were as follows:

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

Financial commitments resulting from orders already placed under purchase agreements related to planned or ongoing capital expenditure projects total E354 million (2000: E446 million). The respective payments are due almost entirely in 2002.

Under collective agreements on part-time work arrangements for certain older employees, we have to accept applications for such arrangements from a certain quota of the work force. Other financial obligations that may arise from such work arrangements in the future cannot be quantified, since the quota has already been exceeded.

In addition, the Group has entered into research agreements with a number of third parties under which Bayer has agreed to fund various research projects or has assumed other commitments based on the achievement of certain milestones or other specific conditions. The total amount of such funding and other commitments is E732 million (2000: E683 million). At December 31, 2001, the remaining payments expected to be made to these parties, assuming the milestones or other conditions are met, were as follows:

[37] RELATED PARTIES

Transactions with related persons and companies, which are invariably performed on an arm's length basis, are mainly trade transactions. The related receivables and payables have been included in the respective notes to the financial statements as required by European Union directives. The revenue and expenses related to these transactions are immaterial to the consolidated financial statements as a whole.

[38] FINANCIAL INSTRUMENTS

Financial instruments entail contractual claims on financial assets. Under IAS 32 (Financial Instruments: Disclosure and Presentation), financial instruments include both primary instruments, such as trade accounts receivable and payable, investments, and financial obligations; and derivative financial instruments, which are used to hedge risks arising from changes in currency exchange and interest rates.

PRIMARY FINANCIAL INSTRUMENTS

Primary financial instruments are reflected in the balance sheet. In compliance with IAS 39 (Financial Instruments: Recognition and Measurement), asset instruments are categorized as "held for trading", "held to maturity", or "available for sale" and, accordingly, recognized at fair value or amortized cost. Changes in fair value are recognized in stockholders' equity. In the event of impairment losses, the assets are written down and the write-downs are recognized in income. Financial instruments constituting liabilities are carried at the higher of nominal and redemption value.

FAIR VALUE

The fair value of a primary financial instrument is the price at which it could be exchanged in a current transaction between knowledgeable, willing parties in an active market. The fair values of other securities included in investments and of marketable securities are derived from their market prices and reflected in the financial statements. Financial obligations are valued mainly on the basis of quoted prices, or in some cases by discounting future cash flows. Their total fair value is E83 million less than their carrying value. The remaining

F-47

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

receivables and liabilities and the liquid assets have such short terms that there is no significant discrepancy between their fair values and carrying amounts.

CREDIT RISK

Credit risk arises from the possibility of asset impairment occurring because counterparties cannot meet their obligations in transactions involving financial instruments.

Since we do not conclude master netting arrangements with our customers, the total of the amounts recognized in assets represents the maximum exposure to credit risk.

CURRENCY RISK

Currency risk is the potential decline in the value of financial instruments due to exchange rate fluctuations. Exposure to currency risk arises mainly when receivables and payables are denominated in a currency other than the company's local currency or will be denominated in such a currency in the planned course of business.

Such risks may be naturally hedged, as when a receivable in a given currency is matched, for example between Group companies, by one or more payables in the same amount, and having an equivalent term, in the same currency. They may also be hedged using derivative financial instruments.

All currency risks arising on financial transactions, including interest, are generally fully hedged. The instruments used are mainly currency swaps, interest and principal currency swaps and forward exchange contracts. Currency risks relating to operating activities are systematically monitored and analyzed. The level of hedging is regularly reviewed.

The position at year end was as follows:

In some cases forecasted transactions are also hedged to further reduce the related anticipated currency risk. At December 31, 2001 the total notional amount of the hedging instruments concerned -- mainly forward exchange contracts for the sale of U.S. dollars or Japanese yen and all maturing before December 31, 2002 -- was E497 million, which is not included in the hedged amount of E2.5 billion. These hedging relationships amount to cash flow hedges as defined in IAS 39. The contracts are concluded monthly so that they run for one year and mature in the middle of each month. On these dates the results of the transactions are recognized in income. In 2001, the differences resulting from fair value measurement and initially recognized in equity amounted to E1.9 million.

On the asset side, 62 percent of currency risks relate to the U.S. dollar and 10 percent to the Japanese yen. On the liabilities side, 60 percent of foreign currency risks relate to the U.S. dollar, while only 4 percent relate to euro risk positions of subsidiaries domiciled outside the euro zone. The remaining exposure involves liabilities in British pounds (3 percent), Japanese yen (5 percent) and a number of other currencies outside the dollar and euro zones. The U.S. dollar accounts for 77 percent of the asset volume hedged through derivative financial instruments, while the pound accounts for 8 percent and the yen for 6 percent. Of the hedged liabilities, 59 percent are in U.S. dollars, 7 percent in yen, 5 percent in British pounds and 29 percent in other currencies. The need for hedging within the euro zone ceased at the beginning of 1999 due to the permanent fixing of exchange rates. When economically hedging exchange rate risk on recorded foreign currency operating items, we

F-48

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

do not aim for hedge accounting treatment. Changes in the fair values of the respective hedging instruments are therefore recognized immediately in income.

The other securities included in investments are almost exclusively denominated in the currency used by the Group company making the investment, so no currency risk is involved. Similarly, the other loans are made only to borrowers in the same currency zone. Where intragroup loans exposed to currency risk have no natural hedge, they are hedged through derivative financial instruments.

INTEREST RATE RISK

An interest rate risk -- the possibility that the value of a financial instrument will change due to movements in market rates of interest -- applies mainly to receivables and payables with maturities of over one year.

Items with such long maturities are not of material significance on the operating side but are relevant in the case of investments and financial commitments. Here, derivative financial instruments are used as the main method of interest rate hedging, though in some cases interest rate risk is not hedged if attractive fixed interest rates can be obtained.

The other securities included in investments are mostly floating rate investments at market rates of interest. Interest rate swaps are not used to convert floating rate investments into fixed rate investments.

The other loans chiefly comprise loans to employees, generally at market-oriented, fixed interest rates. Such loans are exposed to an interest rate risk which, however, is not hedged since it was entered into for specific reasons. More than three-quarters of employee loans are for terms of more than five years.

DERIVATIVE FINANCIAL INSTRUMENTS

The derivatives we use are mainly over-the-counter instruments, particularly forward foreign exchange contracts, option contracts, interest rate swaps, and interest and principal currency swaps. We deal only with banks of high credit standing. The instruments are employed according to uniform guidelines and are subject to strict internal controls. Their use is confined to the hedging of the operating business and of the related investments and financing transactions. "Regular way" purchases and sales of financial assets are recorded at the settlement date in compliance with IAS 39. The main objective in using derivative financial instruments is to reduce fluctuations in cash flows and earnings associated with changes in interest and foreign exchange rates.

MARKET RISK

Market risk arises from the fact that the value of financial instruments may be positively or negatively affected by fluctuating prices on the financial markets. The fair values quoted are the current values of the derivative financial instruments, disregarding any opposite movements in the values of the respective hedged transactions. The fair value is the repurchase value of the derivatives on the closing date, based on quoted prices or determined by standard methods. The notional amount is the total volume of the contracted purchases or sales of the respective derivatives.

* less than E1 million

Gains and losses from changes in fair values are immediately recognized in income, except where the strict conditions for the recognition of a hedge accounting relationship are present. This is also the case with fair value hedges, where the gain or loss on both the hedging contract and the hedged item are recognized in income. However, gains or losses incurred through cash flow hedge accounting are recognized initially in equity and subsequently in the income for the year in which the term of the respective hedging contract is completed.

CREDIT RISK

Credit risk exposure is E139 million (2000: E227 million), this amount being the total of the positive fair values of derivatives that give rise to claims against the other parties to the instruments. It represents the losses that could result from non-performance of contractual obligations by these parties. We minimize this risk by imposing a limit on the volume of business in derivative financial instruments transacted with individual parties.

CURRENCY RISK

Exchange hedging instruments in the notional amount of E2.7 billion (2000:
E3.3 billion) mature within one year, while instruments in the amount of E0.3 billion (2000: E0.2 billion) have longer remaining terms.

INTEREST RATE RISK

Short-term interest rate hedging contracts (including interest and principal currency swaps) total E2.0 billion (2000: E0.3 billion). Those maturing after more than one year total E2.5 billion (2000: E3.2 billion).

HEDGE ACCOUNTING

Most interest rate swaps and interest and principal currency swaps are performed to allow the company to maintain a target range of floating rate debt. All swap contracts amount to permissible hedge accounting relationships and there is no ineffectiveness related to these hedges. Changes in the fair values of derivatives that hedge interest rate risk are recorded as interest expense for the respective periods, as are offsetting changes in the fair value of the related hedged debt items. Fair value hedge accounting is not used in any other circumstances. Some interest rate or interest and principal currency instruments involve a swap from variable to fixed interest rates. Such contracts are accounted for as cash flow hedges as defined in IAS 39. However, most of the cash flow hedges are entered into to protect future operating revenues against currency fluctuations, as explained earlier.

[39] NET CASH PROVIDED BY OPERATING ACTIVITIES

The cash flow statement starts from the operating result. The gross cash flow for 2001 of E2.9 billion (2000: E4.2 billion; 1999: E3.2 billion) is the cash surplus from operating activities before any changes in working capital. Breakdowns of the gross cash flow by segment and region are given in the table on pages F-20 to F-22. The net cash flow of E3.9 billion (2000: E3.1 billion; 1999: E3.2 billion) takes into account changes in working capital.

[40] NET CASH PROVIDED BY (USED IN) INVESTING ACTIVITIES

Additions to property, plant and equipment and intangible assets in 2001 resulted in a cash outflow of E2.6 billion (2000: E2.6 billion; 1999: E2.6 billion). Cash outflows for acquisitions amounted to E0.5 billion (2000: E4.1 billion; 1999: E0.3 billion). Sales of property, plant and equipment led to a cash inflow of E0.5 billion (2000: E0.3 billion; 1999: E0.1 billion), while that from interest and dividend receipts and from marketable securities amounted to E0.4 billion (2000: E0.3 billion; 1999: E0.4 billion).

[41] NET CASH PROVIDED BY (USED IN) FINANCING ACTIVITIES

The net cash outflow of E1.5 billion in 2001 mainly comprises the E1.0 billion dividend payment for 2000 (2000: E1.0 billion dividend payment for 1999; 1999: E0.8 billion dividend payment for 1998) and E0.5 billion (2000: E0.3 billion; 1999: E0.3 billion) in interest payments.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

(1) The 2001 U.S. dollar figures have been translated at an exchange rate of $1.1235 = E1.00. Such translations should not be construed as representations that the euro amounts represent, or have been or could be converted into, United States dollars at that or any other rate.

a. FAIR VALUE OF DERIVATIVE FINANCIAL INSTRUMENTS

Effective January 1, 2001, the Group began applying IAS 39 "Financial Instruments: Recognition and Measurement" and Statement of Financial Accounting Standard ("SFAS") 133, "Accounting for Derivative Instruments and Hedging Activities." As a result, derivative financial instruments are recorded in the balance sheet at their fair values under both IAS and US GAAP. The Group uses foreign currency forward contracts for hedging of anticipated transactions. These forward contracts were recorded at the lower of cost or market value under IAS and were marked to market through the income statement in accordance with U.S. GAAP applicable at the time. The E95 million difference between IAS and U.S. GAAP net income and equity for the year ended December 31, 2000 arose from the recognition of a E95 million gain relating to the anticipated cash flow forward contracts under U.S. GAAP.

During 2001, the fair value of the foreign currency forward contracts that had been entered into during 2000 declined to E68 million. As the hedged anticipated transactions were realized during 2001, this E68 million was recorded as gain under IAS. Conversely, under U.S. GAAP, the E27 million decline in value was recognized as an expense. Therefore, the reconciling item between net income under IAS and U.S. GAAP for the year ended December 31, 2001 of E95 million results from the difference between the E68 million gain under IAS compared to the E27 million expense under U.S. GAAP. Subsequent to the adoption of IAS 39 and SFAS 133, the accounting for new foreign currency forward contracts for hedging of anticipated transactions is consistent between IAS and U.S. GAAP.

b. AVAILABLE FOR SALE SECURITIES

Under IAS, unrealized losses on available-for-sale financial assets are recorded in income only when the decline in market value is considered permanent. Under U.S. GAAP, unrealized losses are recorded in income when they are judged to be other-than-temporary. All declines in market value are considered to be other-than-temporary if they have exceeded 20% over a continual period of 6 months and there is no indication of a significant increase in fair value in the short-term. Principally, other declines in fair value that do not meet these criteria may be considered other-than-temporary depending upon the circumstances surrounding the underlying investment.

Prior to the adoption of IAS 39 in 2001, investments in debt and certain equity securities were reflected in the balance sheet at nominal value less any necessary write-downs under IAS. Under U.S. GAAP, all investments that have been classified as available-for-sale are carried at fair value, with any unrealized gains or losses recorded as a separate component of equity.

c. BUSINESS COMBINATIONS

Prior to the adoption of IAS 22 (revised 1993) on January 1, 1995, the Group wrote-off all goodwill directly to equity in accordance with IAS existing at that time. The adoption of IAS 22 (revised 1993) did not require prior period restatement. Accordingly, a U.S. GAAP difference exists with respect to the recognition of goodwill and amortisation before January 1, 1995. For the purpose of the reconciliation to U.S. GAAP, the pre-1995 goodwill is being amortized through the income statement over estimated useful lives between 20 and 40 years. In addition to the normally recurring amortization expense on these amounts during 2001, the Group wrote-off E22 million of goodwill capitalized under U.S. GAAP. The write-off was due to the planned disposal of the entity to which the goodwill relates.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

d. PENSION PROVISIONS

Under IAS, pension costs and similar obligations are accounted for in accordance with IAS 19, "Employee Benefits". For purposes of U.S. GAAP, pension costs for defined benefit plans are accounted for in accordance with SFAS No. 87 "Employers' Accounting for Pensions". Using an SEC accommodation to foreign private issuers, the Group adopted SFAS No. 87 on January 1, 1994, for its non-U.S. plans, which was also the date of adoption for IAS 19 for those plans. It was not feasible to apply SFAS No. 87 on the effective date specified in the standard. IAS 19 as applied by the Group from 1994 was substantially similar to the methodology required under SFAS No. 87. The adjustment between IAS and U.S. GAAP comprises amortization of the unrecognized transition obligation over the remaining average service lives of employees from 1994 of E238 million, the recognition of an asset limitation under IAS 19, which is not allowed under SFAS No. 87, and the recognition of an additional minimum liability under SFAS No. 87, which is not required under IAS 19.

Following is a reconciliation of the balance sheet and income statement amounts recognized for IAS and U.S. GAAP for both pension and post-retirement benefit plans:

                                                               2001      2000      1999

e. OTHER

There are also differences between IAS and U.S. GAAP in relation to (1) asset impairments, (2) restructuring provisions, (3) equity compensation, (4) other employee benefits and (5) in-process research and development. None of the differences are individually significant and they are therefore shown as a combined total.

ADDITIONAL U.S. GAAP DISCLOSURES

DISCONTINUED OPERATIONS

Under IAS, the Group has classified DyStar, EC Erdolchemie, Haarmann & Reimer and the Fibers business group as discontinuing operations. Under U.S. GAAP, DyStar does not meet the requirements for classification as a discontinued operation, as the formal plan for disposal of these operations will not be completed within one year. The following U.S. GAAP income statement information excludes DyStar as a discontinued operation.

Prior to the adoption of IAS 39, unrealized holding gains on available for sale securities were not recorded under IAS, and gross unrealized holding losses on available for sale securities were recorded in the other financial expense component of financial income, net. Under U.S. GAAP, unrealized holding gains and losses on available-for-sale-securities are recorded as a component of other comprehensive income in all periods presented.

Proceeds from sales of available for sale securities were E195 million, E296 million, and E71 million in 2001, 2000 and 1999, respectively. Gross realized gains were E25 million, E73 million, and E13 million on those sales in 2001, 2000 and 1999, respectively. Gross realized losses were E2 million in 1999 on those sales. There were no gross realized losses in 2001 or in 2000. The gain or loss on these sales was determined using the weighted average cost method.

The maturities of debt securities at December 31, 2001 are as follows:

DERIVATIVE FINANCIAL INSTRUMENTS

The estimated fair values of derivative financial instruments are provided in Note 38 to the Consolidated Financial Statements of the Bayer Group. The use of derivatives is confined to the hedging of the operating business and of the related investments and financing transactions.

FAIR VALUE HEDGES

Changes in the fair value of derivatives that hedge interest rate risk are recorded in interest expense-net each period. The offsetting changes in the fair values of the related debt are also recorded in interest expense-net. Changes in the fair value of derivatives that hedge foreign exchange rate risks are recorded in other non-operating expense-net for each period. The offsetting changes in the fair values of the related debt are also recorded in other non-operating expense-net. The Group maintains no other fair value hedges.

CASH FLOW HEDGES

While each risk management program has a different time horizon, no program currently extends beyond the next one-year period. The effects of hedges of foreign currency-denominated cash receipts are reported in other non-operating expense-net, and the effects of hedges of payments are reported in the same line item of the underlying payment. There was no hedge ineffectiveness reported in earnings in the twelve-months ended December 1, 2001, and no amounts were reclassified to earnings for forecasted transactions that did not occur.

Cash flow hedge results are reclassified into earnings during the same period in which the related exposure impacts earnings. If it appears that a forecasted transaction will not materialize, reclassifications are made sooner.

HEDGES OF NET INVESTMENT IN A FOREIGN ENTITY

The Group does not maintain any hedges of net investment in a foreign entity.

NON-DERIVATIVE FINANCIAL INSTRUMENTS

The U.S. GAAP carrying values are equivalent to the IAS carrying values for all non-derivative financial assets and liabilities, except for marketable securities before 2001, as described above. Non-derivative financial assets consist of cash and cash equivalents, time deposits, and marketable securities. Non-derivative liabilities consist of commercial paper, bank or other short-term financial debts, and long-term debt.

The carrying amount of cash and cash equivalents, time deposits, commercial paper, and bank and other short-term financial debts approximates their estimated fair values, due to the short-term nature of these instruments. The fair value for marketable securities are estimated based on listed market prices or broker or dealer price quotes. The fair value of long-term debt is estimated based on the current quoted market rates available for debt with similar terms and maturities.

Information concerning the fair values of long and short-term financial debt is provided in Note 38 to the Consolidated Financial Statements of the Bayer Group.

PRO FORMA NET INCOME

The Group applies Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to Employees" and related interpretations in accounting for its stock compensation program. Statement of Financial Accounting Standards No. 123 "Accounting for Stock-Based Compensation" would result in the same accounting treatment for the Group's stock incentive plans as was applied under APB No. 25. Hence the additional pro forma disclosures required under SFAS No. 123 do not apply.

PROPORTIONAL CONSOLIDATION

The Group accounts for its investment in 12 joint ventures using the proportional consolidation method, which is the benchmark treatment specified under IAS 31. Under U.S. GAAP, investments in joint ventures generally are accounted for under the equity method. The differences in accounting treatment between proportionate consolidation and the equity method of accounting have no impact on the Group's consolidated stockholders' equity or net income. Rather, they relate solely to matters of classification and display. The United States Securities and Exchange Commission (SEC) permits the omission of such differences in classification and display in the reconciliation to U.S. GAAP provided certain criteria have been met.

Condensed financial information relating to the Group's pro-rata interest in joint ventures accounted for using the proportionate consolidation method is as follows:

SELF-INSURANCE

Various Group companies are self-insured to different degrees. The maximum amount of any Group company's self-insurance is for general liability up to approximately E10 million per occurrence, and product liability up to E14 million per occurrence. For claims against our US subsidiary, the product liability self-insurance is limited to a maximum of E22 million per year. An estimate of the cost of settling existing claims is included under accrued liabilities.

LEGAL PROCEEDINGS

As discussed in Note 29, Bayer is involved in a number of legal proceedings. As a global company active in a wide range of life sciences and chemical activities, we may in the normal course of our business become involved in proceedings relating to such matters as:

- product liability;

- patent validity and infringement disputes;

- tax assessments;

- competition and antitrust; and

- past waste disposal practices and release of chemicals into the environment.

We cannot predict with certainty the outcome of any proceedings in which we are or may become involved. An adverse decision in a lawsuit seeking damages from us could result in a monetary award to the plaintiff and, to the extent not covered by our insurance policies, could significantly harm our business or the result of our operations. If we lose a case in which we seek to enforce our patent rights, we could sustain a loss of future revenue as other manufacturers begin to market products we developed.

In the remainder of this section, we describe what we believe to be the most significant of the proceedings in which Bayer AG or its subsidiaries are currently involved.

PATENT VALIDITY CHALLENGES AND INFRINGEMENT PROCEEDINGS; PATENT-RELATED ANTITRUST ACTIONS

In the United States, Bayer AG and its U.S. subsidiary Bayer Corporation are plaintiffs or co-plaintiffs in a number of patent infringement actions against generic drug manufacturers. The lawsuits arose because these manufacturers filed applications in the United States for regulatory approval of generic versions of products containing the active ingredients ciprofloxacin or nifedipine marketed by Bayer or its licensees. Some of these actions have, in turn, given rise to lawsuits alleging that Bayer AG, Bayer Corporation and other parties had violated federal and state antitrust and similar statutes.

Generic drug manufacturers may receive approval to market formerly patented products after all applicable patent protections have expired. A generic drug manufacturer may, however, attempt to avoid a patent prior to its scheduled expiry by attacking its validity or enforceability. In the United States, the Federal Food, Drug, and Cosmetics Act enables generic manufacturers wishing to market a bio-equivalent version of another manufacturer's product to seek regulatory approval by filing an Abbreviated New Drug Application (ANDA). In its ANDA the applicant must state the basis on which it seeks to avoid any applicable patents.

One basis for seeking approval is a claim that the applicant's product does not infringe existing patent rights or that the patent is invalid or unenforceable. This claim is commonly known as a "paragraph IV certification" or "ANDA (IV)." Under the Act, the filing of a paragraph IV certification is deemed an infringement of patent rights. The Act permits the holder of the patent rights to file an infringement action against the ANDA applicant within 45 days of receiving notice of the paragraph IV certification. If the holder of the patent rights chooses not to file suit within this period, the FDA may approve the ANDA immediately. The filing of a suit, however, stays final FDA approval of the ANDA for a period of 30 months. The court may shorten or extend this period. If the

F-60

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

court rules that the applicant's product will not infringe the patent or that the patent is invalid or unenforceable, the FDA may grant approval immediately. If, on the other hand, the court rules that the product will infringe the patent, the FDA may not grant final approval until the original patent has expired.

Ciprofloxacin-related actions

Patent-related actions. In January 1997, Bayer AG and Bayer Corporation settled a patent infringement suit against Barr Laboratories, Inc. This suit arose when Barr filed an ANDA (IV) seeking regulatory approval of a generic form of Bayer's ciprofloxacin anti-infective product, which we sell in the United States under the trademark Cipro(R). Under the settlement agreement, Barr and Rugby Laboratories Inc., another generic manufacturer that supported Barr during the infringement suit, agreed to dismiss the litigation, acknowledging the validity and enforceability of Bayer's patent rights, and we agreed to pay each company $24.5 million. The agreement gave us the option, until our patent expires in 2003, to supply Barr and Rugby's then parent company Hoechst Marion Roussel Inc. with ciprofloxacin products which they could then market under a license from Bayer using a single trade name, or else to make quarterly cash payments. Since concluding the settlement agreement, we have opted to make payments. Shortly after settling this suit, we applied to the U.S. Patent and Trademark Office for a reexamination of our patent. The Patent and Trademark Office reissued the patent in February 1999.

In April 1999, Danbury Pharmacal Inc., an affiliate of Schein Pharmaceutical, Inc., filed an ANDA (IV) alleging that our ciprofloxacin patent was invalid. Mylan Pharmaceuticals, Inc., an affiliate of Mylan Laboratories, Inc., filed an ANDA (IV) challenging our ciprofloxacin patent in September 1999. To protect and enforce our patent rights, Bayer AG together with Bayer Corporation as licensee filed two lawsuits against Danbury Pharmacal and Schein Pharmaceutical and one lawsuit against Mylan Pharmaceuticals and Mylan Laboratories in 1999, and a second lawsuit against Mylan Pharmaceuticals and Mylan Laboratories in 2000. Reddy Cheminor, Inc. intervened as an additional defendant in the Danbury/Schein suits. All these suits were consolidated for pre-trial proceedings and trial before the U.S. federal District Court for the District of New Jersey.

In their responses the defendants alleged the invalidity and unenforceability of our reexamined patent on several grounds. They then moved for summary judgment on the invalidity issue, and we filed a cross-motion for partial summary judgment. In February 2001, the district court denied the defendants' motion and granted our cross-motion. The court subsequently entered a final judgment in our favor, confirming the validity and enforceability of the patent. The defendants appealed this judgment to the Court of Appeals for the Federal Circuit, which heard oral arguments on January 7, 2002.

In addition, Bayer AG and Bayer Corporation filed a patent infringement action in May 2001 against Carlsbad Technology, Inc., arising from Carlsbad's ANDA (IV) filing seeking regulatory approval of its generic version of Cipro(R). Carlsbad filed two motions for summary judgment. The first motion alleged as a matter of patent procedure that Bayer's patent as it relates to ciprofloxacin should expire in October 2002 and not, as determined by the Patent and Trademark Office, in December 2003. Bayer filed a cross-motion for summary judgment that the expiration date is in December 2003. In its second motion, Carlsbad alleged that ciprofloxacin was obvious in light of the prior art. The federal District Court for the Southern District of California denied both Carlsbad motions in October, 2001 and granted summary judgment to Bayer on its cross-motion. Carlsbad has appealed the decision denying the first motion to the Court of Appeals for the Federal Circuit. A trial regarding the arguments of obviousness raised in Carlsbad's second motion was held in April and May 2002. The Court has not yet made a ruling. Carlsbad has withdrawn all other defenses it had originally raised challenging the validity and enforceability of Bayer AG's ciprofloxacin patent.

If we lost our patent protection for ciprofloxacin, or if the expiration of the patent were accelerated to October 2002, we believe that we would forego significant revenue. We intend to continue taking vigorous action to maintain our ciprofloxacin patent rights in the United States through their normal expiry in December 2003.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

Antitrust actions. Bayer Corporation has been named as a defendant in 39 putative class action lawsuits, one individual lawsuit and one consumer protection group lawsuit filed in a number of state and federal courts in the United States. Bayer AG has also been named as defendant in twenty of these cases, including the individual lawsuit and the consumer protection group lawsuit; it has been served with process in the individual lawsuit and twelve of the putative class action lawsuits. In addition, Barr Laboratories, Aventis S.A., Hoechst Marion Roussel, Inc., Rugby Laboratories, Inc. and Watson Pharmaceuticals, Inc. have each been named as defendant in one or more of these lawsuits. The plaintiffs in these suits allege that they are direct or indirect purchasers of Cipro(R) who were damaged because Bayer's settlement of the Barr ANDA (IV) litigation prevented generic manufacturers from selling a generic version of Cipro(R). The plaintiffs allege that the defendants violated various federal antitrust and state business, antitrust, unfair trade practices and consumer protection statutes, and seek treble damages and injunctive relief.

These proceedings are at an early stage. None of the relevant courts have certified a class. The Judicial Panel for Multidistrict Litigation, or MDL Panel, transferred 35 of these cases to the U.S. federal District Court for the Eastern District of New York for coordinated pre-trial proceedings. The federal court ordered nine of those cases remanded to various state courts in October 2001. Nine cases are currently pending in a California state court. Bayer is also involved in state court proceedings occurring in Florida, New York, Kansas, Tennessee and Wisconsin.

The Barr settlement is also the subject of ongoing antitrust investigations by the U.S. Federal Trade Commission and a number of state attorneys general.

Because these cases in the aggregate allege substantial unquantified damages and also seek treble and punitive damages and penalties, it is possible that the ultimate liability could be material to our results of operations and cash flows. Although we cannot predict the outcome of these cases with certainty, we believe that we have meritorious defenses to the antitrust allegations and intend to defend them vigorously.

Nifedipine-related actions

Patent-related actions. Since 1997 Bayer AG and Bayer Corporation have been involved in a number of patent infringement actions arising from ANDA (IV)s filed by generic manufacturers seeking regulatory marketing approval for allegedly bio-equivalent versions of our brand-name product Adalat(R) CC and Pfizer, Inc.'s brand-name product Procardia(R) XL. The active ingredient of these products is nifedipine. We own patent rights related to nifedipine drug product formulations. In addition, because Pfizer markets Procardia(R) XL under a license from Bayer, Bayer AG and Bayer Corporation became Pfizer's co-plaintiffs in the infringement actions relating to that product.

In August 1997, Bayer AG and Bayer Corporation filed a patent infringement suit against Elan Pharmaceutical Research Corp. and Elan's parent company, Elan Corp., plc, arising from Elan's ANDA (IV) for a drug product containing nifedipine in a 30 mg dosage form. In March 1999, the U.S. federal District Court for the Northern District of Georgia granted summary judgment against us, holding that the particular generic product for which Elan sought marketing approval as described in its ANDA would not violate our patent. In May 2000, the U.S. Court of Appeals for the Federal Circuit affirmed this decision.

In March 2001, the same district court granted summary judgment against Bayer AG and Bayer Corporation in a second ANDA (IV) related suit (60 mg dosage form) that we had filed against Elan and later in another action that we had filed against Elan, Biovail Labs, Inc., Biovail Corp. International and Teva Pharmaceuticals USA, Inc., arising from these parties' commercial sale of an allegedly bio-equivalent nifedipine product. We appealed these decisions to the Court of Appeals for the Federal Circuit. The Federal Circuit vacated these decisions of the District Court and remanded the cases to the District Court for further proceedings.

Bayer AG and Bayer Corporation have also filed four ANDA (IV) related lawsuits against Biovail and two lawsuits arising from the commercial sale of nifedipine products by Biovail and Teva. These suits are currently stayed before the U.S. federal District Court for the District of Puerto Rico.

F-62

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

As defendants have prevailed in some of these lawsuits, it is possible that they may also prevail in the trials and appeals that may take place in the future. We believe, however, that we have meritorious claims in the pending cases, and intend to prosecute these claims vigorously. Because some of our nifedipine dosages have already begun to face generic competition, we do not believe that an adverse result in the pending cases would result in a material amount of additional foregone revenue.

Antitrust actions. Biovail has filed an antitrust lawsuit against Bayer AG, Bayer Corporation and Pfizer in the U.S. federal District Court for the District of Western Pennsylvania. Biovail is seeking a declaratory judgment that Bayer's nifedipine patents are invalid. Biovail also seeks damages under federal and state antitrust statutes alleging, among other things, that Bayer illegally asserted its patent rights. The district court has stayed this litigation pending resolution of the nifedepine-related patent infringement actions against Biovail.

This proceeding is at an early stage. However, we believe that we have meritorious defenses to the antitrust allegations, and we intend to defend this case vigorously.

Product liability proceedings

HIV-related actions. During the past decade, our U.S. subsidiary Bayer Corporation, as well as other fractionators of plasma products, have been involved in lawsuits alleging that hemophiliacs became infected with the human immunodeficiency virus (HIV), or ultimately developed AIDS, by using clotting factor concentrates derived from human plasma. Plaintiffs have brought actions on these grounds in the United States, Ireland, Italy, Taiwan, Argentina, Canada, Japan, and Germany.

In the United States, a class action against Bayer Corporation and three other defendants consolidated the HIV-related claims of more than 6,000 claimants and claimant groups. The parties resolved this class action through a $600 million settlement. Bayer Corporation's share of this settlement was approximately $290 million. Bayer Corporation has also satisfactorily settled nearly 400 lawsuits by plaintiffs who opted out of the class action. Seven suits remain pending in the United States. Although Bayer Corporation has prevailed in the majority of cases that have proceeded to trial, plaintiffs were successful in three cases. The juries in each of these cases awarded damages not exceeding $2 million. In addition, in 1999, a Louisiana jury awarded a plaintiff damages of $35 million. However, the trial court set this award aside, and an appellate court upheld this decision. Bayer Corporation has since settled this matter in the context of a group settlement of nearly 100 Louisiana cases, of which Bayer Corporation's share was less than $50 million.

Although Bayer Corporation intends to defend aggressively the remaining HIV-related lawsuits in various countries, we have made what we believe to be appropriate provisions should these suits result in judgments in favor of the plaintiffs. These provisions are not material to the Bayer Group.

Cerivastatin-related actions. In August 2001, we voluntarily ceased marketing our cerivastatin anticholesterol products in response to reports of serious side effects in some patients. See Item 4, Information about the Company -- Health Care -- Pharmaceuticals -- Products. Since this withdrawal, about 1,700 lawsuits, many of them putative class actions, have been initiated in the United States against Bayer Corporation and Bayer AG. The actions in the United States have been primarily on theories of product liability, consumer fraud, medical monitoring, predatory pricing and unjust enrichment. These lawsuits seek remedies including compensatory and punitive damages, disgorgement of funds received from the marketing and sale of cerivastatin and the establishment of a trust fund to finance the medical monitoring of former cerivastatin users. The federal cases are being transferred to the U.S. federal District Court for the District of Minnesota for coordinated discovery and other pre-trial proceedings. In addition, several actions have been initiated against other companies of the Bayer Group in other countries. We expect additional lawsuits to be filed in the United States and elsewhere. If the plaintiffs in these actions were to be successful, it is possible that the ultimate liability could be material to our results of operations and cash flows. We believe that we have meritorious defenses in these actions and are defending them vigorously. Without acknowledging any liability, we have settled a small number of these cases in the past. We may, on a case-by-case basis, settle additional cases for reasonable amounts when, in our judgment, settlement is economically feasible given the risks and costs inherent in any litigation.

Phenylpropanolamine (PPA) actions. In late 2000, Bayer Corporation discontinued marketing Alka-Seltzer Plus effervescent medicines containing PPA in the United States, Canada and various Latin American countries in response to a recommendation from the U.S. Food and Drug Administration to all manufacturers of drugs and medicines containing PPA. The FDA issued this recommendation after one epidemiological study of a small number of patients suggested a possible association between PPA and hemorrhagic stroke in women of certain ages. More than 540 class and individual lawsuits have been initiated in the United States against Bayer Corporation. The MDL Panel has assigned management of the federal court cases to the U.S. federal District Court for the Western District of Washington. It is probable that additional actions will be initiated there or in other jurisdictions where products containing PPA were marketed. Bayer Corporation believes it has meritorious defenses to these actions and intends to defend them vigorously.

Medicaid Rebate Program allegations

Our U.S. subsidiary, Bayer Corporation, is currently under investigation by the U.S. Attorney's Office for the District of Massachusetts. The investigation, which is assisted by the Department of Health & Human Services, focuses primarily on allegations that Bayer Corporation improperly underpaid rebates under the Medicaid Rebate Program during a period from 1995 to 2000.

These investigations could lead the government to bring criminal or civil actions, or both, against Bayer Corporation. If the government brought such actions and obtained a conviction or verdict against Bayer Corporation, we would likely be required to reimburse the government the amount of the alleged underpayment. We would also become liable to pay civil and/or criminal fines or penalties, which could be substantial. Although we believe this outcome to be unlikely, in the worst case a conviction or adverse verdict could result in the exclusion of Bayer Corporation from participation in federal health programs. Bayer Corporation is providing information to the government and otherwise cooperating with the investigation. Bayer Corporation believes that its practices complied in all material respects with all applicable laws and is therefore seeking to persuade the government to discontinue its investigation. If the government does bring civil or criminal charges against Bayer Corporation, Bayer Corporation intends to defend itself vigorously.

Average wholesale price manipulation proceedings

Seven pending lawsuits allege that a number of pharmaceutical companies, including Bayer Corporation, manipulated the average wholesale price of their products. The suits allege that this manipulation resulted in overcharges to Medicare beneficiaries, Medicaid recipients, state governmental health programs, and private health plans. These suits generally seek damages, treble damages, disgorgement of profits, restitution and attorney's fees. We expect that six of these actions will be consolidated before the U.S. federal court for the District of Massachusetts. The remaining case, in which the State of Nevada is plaintiff, has been removed to federal court in Nevada but may be subject to remand to a state court. Bayer Corporation has not yet responded to the complaints in these actions, but intends to defend itself vigorously.

EFFECT OF NEW ACCOUNTING PRONOUNCEMENTS

U.S. GAAP

Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS No. 137 and No. 138, requires all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income. The adoption of SFAS No. 133 as of January 1, 2001 did not have a material effect on the Group's financial position, results of operations or cash flows.

In June 2001, the Financial Accounting Standards Board approved SFAS 141 "Business Combinations" and SFAS 142 "Goodwill and Other Intangible Assets". SFAS 141 requires the purchase method of accounting to be used for all business combinations initiated after June 30, 2001, establishes specific criteria for the recognition of intangible assets separately from goodwill, and requires unallocated negative goodwill to be written off

immediately as an extraordinary gain. Bayer will apply SFAS 141 to all business combinations for which purchase agreements are signed after June 30, 2001. SFAS 142 addresses the accounting for goodwill and identifiable intangible assets subsequent to their acquisition. Amortization of goodwill will discontinue upon adoption of SFAS 142. In addition, goodwill recorded as a result of business combinations completed during the six-month period ended December 31, 2001 will not be amortized. All goodwill and intangible assets will be tested for impairment in accordance with the provision of this statement. The Group will apply the provisions of SFAS 142 beginning January 1, 2002. Bayer has not completed its analysis of these standards and, accordingly, has not determined what affect the adoption of SFAS 141 and 142 will have on the Group's financial position, results of operations or cash flows.

In June 2001, the Financial Accounting Standards Board approved SFAS 143 "Accounting for Asset Retirement Obligations". SFAS 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. SFAS 143 is effective for fiscal periods beginning after June 15, 2002. Early adoption is encouraged and initial application of this Statement shall be as of the beginning of an entity's fiscal year. The Group will apply SFAS 143 beginning January 1, 2003. Bayer has not completed its analysis of this standard and, accordingly, has not determined what effect the adoption of SFAS 143 will have on the Group's financial position, results of operations or cash flows.

In August 2001, the Financial Accounting Standards Board approved SFAS 144 "Accounting for the Impairment or Disposal of Long-Lived Assets". SFAS 144 retains the requirements of SFAS 121 to recognize an impairment loss only if the carrying amount of a long-lived asset is not recoverable from its undiscounted cash flows and measure an impairment loss as the difference between the carrying amount and fair value of the asset. SFAS 144 requires a probability-weighted cash flow estimation approach and establishes a "primary-asset" approach to determine the cash flow estimation period for groups of assets and liabilities. SFAS 144 is effective for fiscal years beginning after December 15, 2001, and interim periods within those fiscal years, with early application encouraged. The Group will apply SFAS 144 beginning January 1, 2002. Bayer has not completed its analysis of this standard and, accordingly, has not determined what effect the adoption of SFAS 144 will have on the Group's financial position, results of operations or cash flows.

In 2001, the Emerging Issues Task Force (EITF) reached consensus on EITF 00-14 "Accounting for Certain Sales Incentives" and EITF 00-25 "Vendor Income Statement Characterization of Consideration Paid to a Reseller of the Vendor's Products", which address the recognition, measurement and income statement presentation classification of certain sales incentives, and the statement of earnings of consideration from a vendor to an entity that purchases the vendor's products for resale, respectively. We have not yet completed our analysis of the impact of these statements on our financial information presented in accordance with U.S. GAAP.

[45] SUBSEQUENT EVENTS (UNAUDITED)

In October 2001, we entered into an agreement to acquire Aventis CropScience from Aventis and Schering for E7.25 billion. The European Commission approved the transaction in April 2002, and the United States Federal Trade Commission gave its preliminary approval of the transaction under the terms of a consent order on May 30, 2002. Both approvals are subject to the condition that we divest or out-license some of the combined enterprise's products. These conditions require us, among other things, to: divest Aventis CropScience's Fipronil business worldwide, with a right to obtain a co-exclusive license for non-agricultural uses worldwide, except for Europe; divest five Aventis fungicides in Europe and grant a world-wide, non-exclusive license for the Aventis seed treatment products; divest the sugar beet herbicide Metamitron in Europe; divest the broad-spectrum pyrethroid insecticides Cyfluthrin (Baythroid(R)) and beta-cyfluthrin (Bulldock(R)); divest the sugar beet herbicide (Goltix(R)); divest the insecticide Acetamiprid in Europe and North America; divest the wheat herbicide Everest worldwide; and divest Aventis CropScience's cotton defoliant business Folex in the U.S. The total sales value of all divestments is about E650 to 700 million of which about 25 percent comes from the former Bayer Crop protection business and 75 percent from the former Aventis CropScience. The acquisition of Aventis CropScience

F-65

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS OF THE BAYER GROUP -- (CONTINUED)

was closed on June 3, 2002, and we do not expect to make additional major acquisitions in our Crop Protection segment in the near term.

In April 2002, Bayer AG placed benchmark bonds in the European capital market. The total volume of the issue was E5 billion, split into two tranches of a five-year E3 billion bond and a ten-year E2 billion bond.

The tranches carry a 5.375% and a 6% coupon, respectively. The bond proceeds served to finance part of the costs of Bayer's acquisition of Aventis CropScience. The remaining price will be covered through the ongoing issuance of commercial paper.

In May 2002, we decided to retain our Fiber business as part of polymers, because presently the market is not prepared to pay an appropriate price for this business. We will include the Fiber business in our continuing operations for all periods beginning with the second quarter of 2002. Continuing the business offers better prospects for success than a divestment. As a result of the present review process of the fibers' activities, an impairment write-down affecting the operating results of polymers substantially may arise.

On June 4, 2001 we sold the remaining 30 percent stake in Agfa for a gain of approximately E200 million.

TOTAL REMUNERATION OF THE BOARD OF MANAGEMENT AND THE SUPERVISORY BOARD, ADVANCES AND LOANS

The remuneration of the Board of Management for 2001 amounted to E8,153,562. Emoluments to retired members of the Board of Management and their surviving dependants amounted to E8,355,270.

Pension provisions for these individuals amounting to E69,341,493 are reflected in the balance sheet of Bayer AG.

The remuneration of the Supervisory Board amounted to E1,293,750.

There were no loans to members of the Board of Management or the Supervisory Board outstanding as of December 31, 2001, nor any repayments of such loans during the year.
