ITEM 1. BUSINESS.

CORE, INC. is a national provider of employee absence management services to Fortune 500 companies and other self-insured employers, third-party administrators and insurance carriers. CORE's services include Integrated Disability Management (which consist of CORE's proprietary WorkAbility-Registered Trademark- Absence Management program, disability reinsurance management services, social security disability benefits advocacy, analytic consulting services, onsite job profiling analysis and workplace risk management services, and licensing), Peer Review Analysis (which consist of specialty physician and behavioral health review services), and other services including Medicare coordination of benefits, health care benefits utilization review and case management services. CORE's services are designed to prevent absence, promote early return to work, improve productivity, and manage disabilities from "day one" through return to work or retirement, without compromising the quality of health care services provided to patients.

CORE's Integrated Disability Management services include monitoring the appropriateness of absences and durations under short and long-term disability plans, family medical leave and similar plans, and workers' compensation programs, in order to reduce unnecessary absenteeism and its related costs of wage replacement, hiring and training replacement personnel and lost productivity. These services are provided through CORE's WorkAbility program, which uses a proprietary software program developed and supported through the statistical analysis of disability utilization data collected over a 10-year period. CORE's WorkAbility program provides an objective, medically based method for recommending and monitoring employees' return-to-work status. The WorkAbility program is designed to obtain and analyze relevant medical and work-related information with the initial onset of the employee's absence and thus assure that the employee, attending physician and employer all have reasonable and consistent expectations as to the projected return-to-work date. CORE's reinsurance and group disability risk management services include providing marketing, underwriting advice, claims, actuarial and compliance services to its insurance company clients and risk management expertise for reinsurers in a reinsurance facility. CORE's social security disability benefits advocacy program provides assistance to disabled employees with obtaining their Social Security Disability Insurance benefits.

CORE's Peer Review Analysis program provides pre-certification, concurrent, appellate, retrospective, medical policy, quality and forensic independent specialty physician review services for use within utilization management programs of CORE's insurance company and self-insured corporate clients. CORE believes its more than 330 Board certified physician reviewers comprise the largest independent physician review service in the country. CORE's behavioral health review program provides comparable review service by psychiatric specialists in specialties such as general, child and adolescent and addiction psychiatry.

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and CORE's actual results could differ materially from those contemplated by such statements. Such statements reflect management's current views, are based on many assumptions and are subject to risks and uncertainties, including those described in the subsection entitled "Risk Factors," below.

HISTORY OF CORE

CORE was incorporated in Massachusetts in April 1984 under the name Peer Review Analysis, Inc. ("PRA") to provide physician-intensive utilization management services to commercial insurance companies and self-insured employers. PRA became a publicly held entity in December 1991 with the completion of an initial public offering.

In March of 1995, PRA completed its merger (the "CMI/PRA Merger") involving Core Management, Inc., a Delaware corporation ("CMI"). CMI was incorporated in 1990 to acquire the health and disability cost management services business (including the WorkAbility program) of Health Data Institute, Inc., a subsidiary of Baxter International, Inc. In April 1993, CMI acquired the mental health case management services business of Integrated Behavioral Health, a California corporation ("IBH"). In July 1995, CORE changed its name from Peer Review Analysis, Inc. to CORE, INC.

In October 1995, CORE acquired all the capital stock of Cost Review Services, Inc. ("CRS"), a regional workers' compensation bill audit firm. In June 1997, CORE purchased certain of the assets of Social Security Disability Consultants and Disability Services, Inc. (collectively, "SSDC"), a disability management services firm which provides social security disability benefits advocacy and Medicare coordination of benefits. In July 1997, CORE purchased the assets and certain liabilities of Protocol Work Systems, Inc. ("PWS"), a provider of job analysis, employee physical agility testing and other loss prevention services to the workers' compensation market. In March 1998, a wholly-owned subsidiary of CORE, TCM Services, Inc. ("TCM"), acquired substantially all of the assets and certain liabilities of Transcend Case Management, Inc. ("Transcend"), a regional provider of workers' compensation case management services. In September 1998, CORE acquired all shares of stock of Disability Reinsurance Management Services, Inc. ("DRMS"), a full-service reinsurance intermediary manager.

In October 1998, CORE discontinued the operations of CRS. In December 1998, TCM transferred substantially all its assets and certain liabilities to Transcend following the exercise by Transcend of its option to reacquire the assets, as described in the Asset Purchase Agreement dated March 17, 1998. In June 1999, CORE sold the assets of IBH to a non-affiliated party.

CORE's executive offices are located at 18881 Von Karman Avenue, Suite 1750, Irvine, California 92612, and its telephone number at that address is
(949) 442-2100.

INDUSTRY OVERVIEW

In recent years, large corporations have begun to recognize the magnitude of the annual cost of occupational and non-occupational injuries and illnesses, which according to one 1999 study represented 12.8% of total payroll costs. These expenses present a significant challenge to corporate productivity. CORE estimates that total U.S. costs due to injury and illness-related workplace absence will reach $340 billion for the year 2000, double what they were in the early 1990's.

According to industry sources, disability costs including workers' compensation expenditures grew at an average annual rate of over 18% from 1990 through 1996, and CORE believes this growth is continuing. CORE estimates that workers' compensation costs were approximately $80 billion in 1998. Despite the general awareness of this high level of workers' compensation costs, expenditures for group disability (including short-term disability and long-term disability plans), sick pay and family leave represent a far larger share of total expenditures estimated at 60% to 75% of total disability costs. Two driving factors behind the increase in group disability and workers' compensation expenditures are workplace and legislative changes. Work-related changes that have contributed to rising benefits costs include the aging of the active workforce, increased volatility in hiring and layoffs (which often results in increased benefits utilization) and increased diagnoses of repetitive stress-related injuries. Also contributing to rising disability benefit costs and awareness are legislative changes such as the Family and Medical Leave Act and the Americans with Disabilities Act, which mandate accommodation for family circumstances and disabled workers, which both have a growing impact on accommodation and lost time issues.

In response to these rising costs, a variety of insurance companies, managed care organizations and self-insured employers have used various cost reduction techniques, often borrowed from group health managed care, including securing pricing concessions from providers, using case management tools, and implementing "gatekeepers" as a means to control utilization. However, these managed care initiatives focus almost entirely on medical costs generated after a disability claim is received, not on the more significant productivity (lost time) impacts of employee ill health. Furthermore, work absence duration, and consequently disability payments, have traditionally been driven by the decision of the treating physician. While workers' compensation cases are typically attended by an occupational specialist, employees with non-occupational disabilities tend to utilize their own primary care physician who have little or no interaction with the employer and limited sensitivity to productivity (lost time) issues.

As traditional managed care tools become standard industry-wide, they are generating diminishing marginal savings for employers, who must find more aggressive and sophisticated utilization review mechanisms to yield further savings. In addition, the new-found awareness of the additional costs associated with workplace absence has brought with it an increasing demand for cost saving strategies that address both health care expenditures and the productivity impact of an employee's ill health. Tight labor markets and global competition have focused Corporate America on achieving real productivity gains. With the importance of each job magnified, employers are actively looking for new tools to help control

4

workplace absence. Until recently, recognition and management of these productivity costs have been impaired by their difficulty in measurement, the fragmentation of responsibilities for disability programs within human resources and risk management departments of most corporations and the historical focus on group health managed care.

While a small group of companies is emerging that are applying managed care principles to the workers' compensation industry, historically there have been few, if any, companies focusing on the provision of managed care techniques to the broader disabilities market. With the support of its analytic and physician services, CORE's products provide employers with an integrated and comprehensive approach to disability benefits management.

WORKABILITY ABSENCE MANAGEMENT PROGRAM

CORE estimates that total direct and indirect expenditures for medically-related workplace absence are 25% of the related to workers' compensation payments. The cost of absenteeism includes wage replacement, the costs of hiring and training replacement personnel and lost productivity. CORE's WorkAbility Absence Management Program provides for the monitoring of the appropriateness of absences and their duration under short and long term disability plans, family medical leave and similar plans, and workers' compensation programs. The program is focused on reducing unnecessary absenteeism and the costs associated with such absences, thereby improving workplace productivity.

The WorkAbility program is built on the foundation of a proprietary software system developed by CORE and maintained through the statistical and clinical analysis of disability utilization data. The WorkAbility program allows CORE to work with employee's physicians to establish expected absence duration using duration guidelines that are specific and objective. These guidelines are packaged in a software module called WorkAbility On-Line Medical Protocols (WOMP). WOMP is proprietary to CORE. The WorkAbility program, which contains WOMP, was developed along six key absence management concepts:

DAY ONE INTERVENTION. Unlike retrospective disability review which is triggered only after an extended employee absence or after significant costs have been incurred, the WorkAbility program is designed to facilitate absence management from the first day of the absence (or sooner, in the case of planned absences such as elective surgery or childbirth). This proactive approach allows return-to-work

5

expectations to be set early with the doctor, the patient and the workplace, and supports efforts to return patients to work on modified hours or with modified duties.

PROPRIETARY TECHNOLOGY AND DATABASE. CORE began developing its WorkAbility program in 1986. The WOMP protocols are regularly updated using COREbase, a database of more than 650,000 disability and workers' compensation records collected by CORE over a period of more than 10 years. This database-driven updating process allows CORE to field absence duration guidelines that are based on actual return-to-work experience. The database continues to grow as CORE adds more clients, and as clients integrate across more lost time benefits.

CLINICAL COLLEGIALITY AND CREDIBILITY. The WorkAbility program is based on conducting a clinically credible dialog with an employee's physician to reach agreement on an appropriate return-to-work plan. The clinical depth and complexity of the WOMP protocols support this activity by providing a foundation of clinical credibility. Our approach is focused on making this dialog a collegial interaction.

CONCURRENT REVIEW. In addition to the initial recommendation of an appropriate return-to-work plan, the WorkAbility program includes ongoing review of the progress of the case. The information from these subsequent reviews add to the cumulative database driving the development of the protocol system, thereby ensuring that the guidelines serve both the initial review, as well as the sequential reviews over time as an illness or injury progresses toward return to work.

COMPLETE WORKFORCE COVERAGE. The WorkAbility program is designed to cover all workplace absences, not only the longer term and more costly absences. The WOMP protocols cover over 10,000 clinical endpoints for medical conditions and surgical procedures. The breadth of the protocols ensures consistent return-to-work planning, regardless of whether the condition causing the absence is a result of workplace injury covered by workers' compensation or an injury occurring outside of the workplace covered by a disability plan.

FLEXIBILITY. The system is designed to allow CORE to customize the product and services to meet client needs and culture. The guidelines are based on a statistical distribution so that a client can choose how to monitor and to manage durations. The system generates communications that are all customized to the client's benefit plan. In addition, depending on the technical capability of the client, other modalities such as e-mail, intranet and internet can be used to disseminate information on claim approvals and status.

The WorkAbility software system is used by customer service representatives and registered nurse reviewers to assess each disability claim in the early stages of an employee's absence. Under the WorkAbility program, the employee contacts CORE and the employee's eligibility for the benefit is assessed using information previously supplied by the employer and loaded onto CORE's system. Once eligibility is determined, CORE's nurse reviewer contacts the employee's physician or office staff (depending on the severity of the case). The nurse reviewer enters information on the diagnosis and severity of the condition into CORE's proprietary WorkAbility system. The return-to-work plan is established by the nurse using the WorkAbility program's automated clinical protocols. The protocols consider such factors as the employee's age and general health, job requirements, symptoms and severity of the condition, diagnosis of the attending physician, treatment plan, medical procedure(s) performed, prognosis for recovery and comorbid factors in establishing a recommended absence duration.

To assure consistency, reviews are guided by program standards based on both statistical and clinical analysis and, in certain circumstances, are referred to physicians for further review. If CORE and the attending physician agree with respect to the anticipated absence duration, letters stating the expected return-to-work date are sent to the employee and physician on the date the review is completed. The employer is notified of the return-to-work date electronically. If the employee's physician disagrees with the suggested return-to-work plan (as occurs in less than 15% of the cases), the case is referred to a WorkAbility physician advisor who will discuss the case with the treating physician. In the event that they cannot reach agreement, the case is referred to the employer for consultation to determine whether or not an independent medical examination (IME) should be requested. IMEs are required in fewer than 2% of the cases. If the employee's condition or medical treatment changes during the absence or the employee is not ready to return to work on the expected date, a request for an extension of the absence is reviewed on a case-by-case basis using the WOMP duration guidelines with the additional information provided by the attending physician and/or patient.

6

In general, CORE's WorkAbility services are advisory only. The attending physician and the patient remain responsible for determining the work-absence period and all other aspects of the plan of treatment. Generally, the employer or other payor is responsible for making all decisions with respect to the payment or denial of benefits under the applicable benefits plan. Certain clients, including Bell Atlantic Corporation, have delegated to CORE the authority to decide whether an employee is eligible for benefits under the client's plan.

In addition to direct absence management activities, the WorkAbility program provides to clients reports that track utilization and cost trends and return-to-work plan performance. In addition to the standard report package, clients can obtain additional services, such as adding health care claims to provide a more complete picture of the clinical factors and costs associated with disability. Clients with integrated benefits often customize the reporting packages to present their utilization separately by plan (e.g. short-term disability, long term disability) as well as on a combined basis.

DISABILITY REINSURANCE MANAGEMENT SERVICES

DRMS, acquired by CORE in September 1998, is a reinsurance intermediary providing turnkey disability reinsurance and management services for insurance company clients marketing other forms of employee benefit products such as medical, dental, and group life insurance. DRMS provides a comprehensive array of services designed to increase its clients success at marketing disability products. These services include strategic planning, sales and marketing, product development, actuarial, underwriting, claims management and compliance services. DRMS' customer-focused team uses proprietary systems to provide creative solutions and day-to day decisions quicker and more efficiently than its competitors.

As a reinsurance intermediary, DRMS does not assume insurance risk. Reinsurance risk protection to DRMS' clients is provided through the Disability Alliance for Reinsurance Treaties ("DART"). The lead reinsurer for DART assumes the risk from DRMS clients and passes on portions of it to a group of participating reinsurers. In addition to managing the reinsurance risk, DRMS provides accounting and administrative services to DART.

During 1999, DRMS began providing additional long-term disability services to CORE customers. Through DRMS, CORE also provides an insurance option to CORE clients. Finally, DRMS' network of insurance contacts bring opportunities for CORE to provide services to insurance carriers.

SOCIAL SECURITY ADVOCACY

CORE's social security disability benefits advocacy program includes claim file reviews, auditing, designing and implementing Social Security assistance programs, and representation and assistance with Social Security claims and appeals. CORE's model is unique in that it integrates all aspects of the Social Security process, producing a streamlined, efficient and effective service.

CORE ANALYTIC

In addition to the services provided to WorkAbility clients, CORE Analytic provides data analysis and consulting services directly to large corporate clients. These services include in-depth customized information concerning their disability and health care costs and utilization experience. Health care costs, disability costs and workers' compensation costs are often under separate departments in a large employer (human resources, benefits and risk management), which has historically impaired corporations' ability to recognize the magnitude of, and to manage, these costs. The basic objectives of CORE's Analytic services are to help employers and insurers obtain better value for their disability, workers' compensation and health care expenditures with a company's specific goals in mind. CORE assists in identifying the best means to reduce the total costs of these benefits or slow the rate of increase, enhance the appropriateness and quality of care, predict future benefit costs and increase the return on investment from managed care programs. CORE's Analytic consulting services can coordinate and analyze information on a company-wide basis and use the client's information and CORE's proprietary disability and medical cost data analysis methodologies to simulate changes in a benefit plan's structure and the resulting impacts on overall benefit program cost. For example, CORE serves as a data partner to several Fortune 500 companies and provides quarterly "CORE Impact Reports" on integrated claims experience of the client covering disability, workers' compensation and group health benefits.

PROTOCOL WORK SYSTEMS

The JobSafe program of CORE's Protocol Work Systems division provides on-site job profiling and functionality assessments in a program that compares the physical agility of each worker with the actual demands of the job to create a

7

safer working environment. The JobSafe program is tailored to each client's specific facility to help ensure compliance with the Americans with Disabilities Act, Occupational Safety Health Administration regulations and quality control requirements of ISO 9000. The program begins with an on-site tour of the client's facility. The tour is followed by a meeting with supervisors, interviews with employees, and the collection of measurement and weight statistics. Job descriptions then are created, videotapes are produced with descriptive commentary for each job, and finally, physical agility testing of each employee is conducted. The process culminates with a compilation of information for the client, along with instructions on how to operate the program.

LICENSING

In addition to the key role the WOMP protocols plays within the WorkAbility software system, the WOMP protocols have also been licensed by CORE to third parties as a separate product. These WorkAbility protocols are updated annually to, among other things, reflect recent advancements in medical technology and procedures, and to update the recommended disability durations using the collective experiential data collected by CORE through its services to clients.

PEER REVIEW ANALYSIS

Peer Review Analysis includes the following products and services:
Physician Review Services
Behavioral Health Review

PHYSICIAN REVIEW SERVICES

CORE's independent specialty physician review program, known commercially as Peer Review Analysis or PRA, provides pre-certification, concurrent, appellate, retrospective, medical policy, quality and forensic physician review services for use with existing utilization management programs of clients, including insurance carriers that service the group health, disability and workers' compensation markets, and other managed care companies. CORE believes its more than 330 Board certified physician reviewers comprise the largest independent physician review organization in the country. CORE's consulting relationship with this large base of physicians has positioned CORE to offer an independent external appeal review service, which is mandated under several state laws and generally requires specialty-matched reviews. CORE believes that appellate review is one of the growing sectors of the otherwise mature health care utilization management industry.

When a client's nurse reviewer determines that a case does not meet the client's established criteria, the nurse reviewer will forward a referral to CORE. The referral describes the principal diagnosis of the patient and the reason for referral for physician review. In most instances the reason for referral is based upon a question of medical necessity or therapeutic benefit of a proposed treatment plan. CORE's independent physician reviews the case information, which will have been previously entered into CORE's data processing systems, and then telephones the attending physician to ascertain any additional clinical data, the attending physician's rationale for the proposed treatment plan or the proposed length of hospital stay. Based on discussions with the attending physician, including, when appropriate, discussions of possible alternative treatment plans, and using clinical judgment as well as criteria based on national norms, CORE's physician makes a recommendation concerning the appropriateness of the proposed or revised treatment plan.

CORE then notifies its client of its recommendation regarding the medical necessity or appropriateness under the client's health care benefit plan of the proposed treatment plan, hospitalization or length of stay. If the proposed hospitalization is not certifiable as such under the plan, the payor typically denies or reduces the payment of benefits for the proposed hospitalization. The decision of the payor may be appealed by the patient or the attending physician. In such event a second CORE independent physician of the same specialty who was not involved in the original decision will review the case on the merits of the clinical criteria or any additional information.

8

Reviews under CORE's specialty physician review program are managed from CORE's offices, and the majority of all review decisions are completed within 24 hours of referral. In most instances, CORE's physician review services are advisory in nature. Determinations as to the payment or denial of benefits are typically made by the third party payor, and the patient and the attending physician make decisions as to the patient's medical treatment.

CORE is certified by the American Accreditation HealthCare Commission ("AAHC/URAC") to perform various utilization review functions. AAHC/URAC is a nationally recognized organization that has developed standards to encourage the availability of effective, efficient and consistent utilization review of health care services throughout the United States. One of AAHC/URAC's objectives is to establish standards for the procedures used to process appeals of utilization review determinations. Many of CORE's clients rely on CORE's specialty physician and behavioral health review services to comply with AAHC/URAC's appellate procedures.

BEHAVIORAL HEALTH REVIEW

CORE's behavioral health review program provides psychiatric review services similar to CORE's specialty physician review services by psychiatrists who are supported by a team of multi-specialty physicians. CORE's independent psychiatrists include specialists in various psychiatric specialties such as general psychiatry, child and adolescent psychiatry and addiction psychiatry. CORE believes that its multi-specialty psychiatrists and CORE's emphasis on intensive specialty review distinguish it from psychiatric review performed by other utilization management firms and better addresses the more subjective nature of many behavioral health reviews.

EXITING/EXITED SERVICES

Operations within the exiting/exited services line ceased in 1999. The line had included the following products and services:
Regional workers' compensation field case management (CRS and TCM) Regional workers' compensation bill audit (CRS) Integrated Behavioral Health (IBH)

On June 21, 1999, CORE sold the assets of IBH, a provider of mental health case management services, to a non-affiliated third party. This sale completed our strategic decision to focus on building CORE's leadership position in employee absence management services and to exit certain businesses in which market leadership or sufficient profit margins did not appear to be attainable. Both CRS and TCM were exited during 1998.

9

OTHER SERVICE LINES

Other service lines includes the following products and services:

Utilization Review and Case Management
Medicare Coordination of Benefits

UTILIZATION REVIEW AND CASE MANAGEMENT

CORE provides medical and behavioral health utilization review and case management services to Fortune 500 companies and other self-insured employers, third-party administrators ("TPAs") and an insurance carrier. CORE's services are designed to evaluate the medical necessity and appropriateness of health care services prescribed for participants in health care benefits plans, including hospital admissions, proposed length of hospital stay, use of outpatient facilities and other treatment alternatives. In cases of high cost diseases, conditions or catastrophic illnesses, CORE may also render case management services of individual cases in order to assure that cost-effective treatment alternatives are utilized. Clients may elect to contract for all of the services offered under the programs or, in the alternative, may elect to contract for only certain portions of services offered.

CORE provides its utilization review services and case management services through a staff consisting primarily of registered nurses and physicians. Clients which utilize CORE's utilization review programs advise their participants of review requirements including the requirement to contact CORE within a specified period of time. From these contacts, CORE's medical and behavioral health review staff gathers the necessary personal and medical information and enters this information into CORE's review system. Based on this information and using CORE's review criteria, CORE conducts its review.

For cases requiring intensive case management, CORE assigns a nurse case manager to the case. These nurse reviewers work with providers and insurers to provide the appropriate health care benefits to patients facing catastrophic or chronic illness.

CORE plans to continue to offer these services to support our existing clients, especially those who have integrated their medical and disability case management programs. Our ability to manage catastrophic cases with an absence management perspective continues to provide value to CORE by building relationships with providers and expanding our clinical credibility.

MEDICARE COORDINATION OF BENEFITS

Through its SSDC subsidiary, CORE provides services to help large employers identify those employees or retirees who should be receiving Medicare benefits. CORE then assists the client in establishing or documenting Medicare primacy, identifying the health care plan payments and costs that can be offset by Medicare, and implements an overpayment recovery program.

Because this product is geared toward the large employer client, one of CORE's target markets, CORE will continue to market and provide these services.

10

CLIENTS AND MARKETING

CORE has over 350 customers across the country, including numerous Fortune 500 companies. Revenues from Fortune 500 companies accounted for approximately 69% of total revenues in 1999. The following is a selected list of CORE's clients which, CORE believes, is representative of its overall client base:

- BELL ATLANTIC CORPORATION
- BMW
- BRISTOL-MYERS SQUIBB
- CHAMPION INTERNATIONAL CORPORATION
- CNA INSURANCE COMPANY
- COMMONWEALTH OF VIRGINIA
- DAIMLERCHRYSLER
- DANA CORPORATION
- GENERAL ELECTRIC CORPORATION
- GTE COMMUNICATIONS SYSTEM CORPORATION
- LIBERTY MUTUAL INSURANCE COMPANY, INC.
- MEDICAL MUTUAL OF OHIO
- MOTOROLA CORPORATION
- PCS HEALTH SYSTEMS, INC.
- RELIASTAR FINANCIAL CORP.

CORE markets its services primarily to national, direct accounts, including self-insured employers, and through group health and disability insurance carriers and third party administrators.

During 1999 and 1998, Bell Atlantic Corporation represented 19% and 21%, respectively, of total revenues. No other client represented more than 10% of total revenues. During the years ended December 31, 1999 and 1998, CORE's five largest clients represented 43% and 45%, respectively, of total revenue.

CORE typically enters into service agreements with its clients. These agreements have automatically renewable successive terms of between one and three years, but are generally terminable upon 60 to 90 days notice. They do not generally provide for minimum payments and are usually non-exclusive. Certain contracts include provisions that the fees payable to CORE can vary based upon CORE's performance and the savings achieved by the client under the contract.

For many of its programs, CORE charges its clients a "capitated fee" (i.e., a fixed per employee per month ("PEPM") fee or a fixed per employee per quarter fee). The amount of this fee varies depending on the number and type of review programs selected by the client and the size of the client. For other services, CORE charges fees on an hourly, per case, percentage of risk premium (for turnkey and reinsurance management services) or percentage of cost recovery (for social security advocacy and Medicare programs) basis rather than a capitated basis. Notwithstanding the outcome of CORE's review, decisions as to the payment or denial of benefits and eligibility or coverage under the benefit plan are typically made by the administrator of the participant's health care plan, not by CORE.

The patient and the attending physician always make decisions as to the patient's medical treatment, not CORE. However, for several clients, CORE accepts fiduciary responsibility for their disability benefit programs. CORE's confidence in its clinical decisions permits it to assume these responsibilities. CORE charges increased fees to those clients for which it serves as a plan fiduciary.

11

INFORMATION SYSTEMS

CORE's key products and services are supported by administrative software that was developed and is maintained by in-house staff. Each of these software programs incorporates e-mail and other external data exchange features for client and remote user communications.

CORE's wide area network ("WAN") is designed to support the organization's rapid growth. A scalable architecture has provided flexibility, allowing for timely deployment of upgraded facilities in response to the business' needs. Additionally, CORE provides for alternative backup WAN capability that will assure continuous business operations during network outages. Another ongoing initiative within information systems development is the continual implementation of available information technology to significantly enhance the productivity of all CORE's key products and services. This includes, specifically, the integration of imaging, network fax computer integrated telephony, and Internet technologies into the workflow. Additionally, CORE's largest WorkAbility client has direct access to real-time information via an Extranet. This "self service" model application provides for both the initiation, as well as, the checking of status on claims on a near 24 hours by seven days per week basis.

The WorkAbility-Plus system, CORE's multi-tier, client/server technology based application, has provided for the ability to migrate rapidly into expanding business opportunities. CORE continues to expand its industry leading capabilities in regard to the family medical leave ("FML") business. Totally integrated with other absence management capabilities, the FML module provides robust capabilities tailored to Federal guidelines as set forth in the Family and Medical Leave Act and other state sponsored legislation. This architecture is designed to allow for client server operation and rapid feature development. Additionally, CORE continues to evolve the system capabilities in regard to the management and payment of long-term disability claims. Integration with software developed by CORE's subsidiary, DRMS, was completed in 1999. The WorkAbility-Plus application utilizes software architecture that provides maximum flexibility in attaching industry-standard databases to support growth and varying client needs. CORE believes that this architecture will support the integration of additional absence management capabilities.

Funding for the initial development of CORE's WorkAbility software (original version) was provided by Chrysler Motor Corporation ("Chrysler") in exchange for a perpetual, non-exclusive, non-transferable license to use such software. Ownership of the WorkAbility software has been retained by CORE, which has the exclusive right to market the software to others.

GOVERNMENT REGULATION; HEALTH CARE REFORM

A number of states, including several of those in which CORE transacts business, have extensive licensing and other requirements applicable to CORE's business. Additionally, CORE's clients, including insurance companies, are subject to regulations that indirectly affect CORE.

The laws of many states regulate the provision of health care utilization management services. These regulations generally require the provider of utilization management services to be reasonably accessible by telephone to doctors and patients, to have adequately qualified personnel, to provide physicians and patients a procedure to appeal determinations of non-reimbursement, and to maintain the confidentiality of patient records. Other states regulate the provision of claims administration services and preferred provider organizations which may affect CORE. CORE believes it is in compliance with all applicable regulations governing the provision of managed health care services in the states where CORE is subject to such regulations, as currently in force and as currently interpreted.

CORE's operations depend upon its continued good standing under applicable laws and regulations. To date, the cost of compliance has not been material. Such laws and regulations, however, are subject to amendment or new interpretation by authorities in each jurisdiction. If amended regulations or new interpretations of federal or state laws or regulations arise, CORE, may have difficulty complying without significant expense or changes in operations. CORE is unable to predict what additional government regulations, if any, directly or indirectly affecting its business may be promulgated. Although CORE believes that it is currently in compliance with applicable regulations in those states in which it is subject to regulation, CORE's business could be adversely affected by a revocation of or failure to obtain required licenses and governmental approvals, a failure to comply with applicable regulations or significant changes in regulations applicable to its clients.

12

In addition to existing government health care regulation, there have been numerous initiatives at the federal and state levels, as well as by third-party payers, for comprehensive reforms affecting the payment for and availability of health care services. CORE believes that such initiatives will continue during the foreseeable future. CORE is unable to predict what, if any, reform initiatives may be adopted, or what effect, if any, their adoption may have on CORE.

COMPETITION

CORE presently competes in two different markets: (1) managed disability and workers' compensation and (2) health care utilization management.

The managed disability and workers' compensation market is a developing market, which is highly competitive. Competitors include both new companies focused solely on the workers' compensation market and large established disability insurance carriers who have traditionally dealt with disability from an underwriting rather than an employee productivity perspective. Some of the competitors are significantly larger and have greater financial and marketing resources than CORE. CORE competes on the basis of quality and cost-effectiveness in this market, and CORE believes that its proprietary disability management protocols and database of clinically defined disability episodes give it a significant competitive advantage.

The health care utilization management market is fragmented but is consolidating rapidly as national health care reform and other forces drive independent utilization review and cost management firms into niche markets or to consolidation with large insurance carriers and provider groups. The health care utilization management market is also highly competitive. Competitors include large established insurance carriers and large managed care organizations. Some of the competitors are significantly larger and have greater financial and marketing resources than CORE. CORE competes on the basis of quality, cost-effectiveness and service.

EMPLOYEES AND PHYSICIAN CONSULTANTS

In addition to its available staff of over 330 physician consultants covering the major medical specialties, CORE has over 625 employees. Generally, CORE's physician consultants are paid by CORE on a per hour or per case review basis. Almost all of CORE's physicians are retained by CORE as independent contractors and also maintain active practices. The majority of CORE's physicians work between 5 and 20 hours per week for CORE. Compensation to CORE's reviewers is not related to any cost savings achieved by CORE's clients.

RISK FACTORS

The factors listed below represent certain important factors CORE believes could negatively affect its business. These factors are not intended to represent a complete list of the general or specific risks that may affect CORE. Investors should recognize that other risks may be significant, presently or in the future, and the risks set forth below may affect CORE to a greater extent than indicated.

RELIANCE ON WORKABILITY-REGISTERED TRADEMARK- PROGRAM. Part of CORE's strategy is to focus its growth efforts on, and commit significant management, marketing and other resources to expanding, its managed disability services, and in particular its WorkAbility disability management program. CORE's focus on its managed disability services may not ultimately be profitable.

CORE's managed disability services depend on its WorkAbility computer software. CORE's ability to continue to derive revenue from the WorkAbility software depends, in part, on maintaining its proprietary and confidential nature. CORE relies on a combination of database size, trade secret, copyright, trademark and contractual protections to establish and protect its proprietary rights to the WorkAbility software. The precautions taken by CORE may not be adequate to prevent misappropriation or re-creation of CORE's database. In addition, these protections and precautions will not prevent development by independent third parties of competitive technology or products, and some companies have developed products which, to some extent, perform functions similar to those performed by the WorkAbility software.

DEPENDENCE ON KEY CLIENTS. Contracts with several key clients account for a substantial portion of CORE's

13

revenues. The majority of CORE's contracts with its clients, including those with its major clients, permit cancellation by the client upon 90 days' notice, while certain other of CORE's contracts permit immediate cancellation under certain circumstances. The failure to renew, the exercise of cancellation rights or a significant reduction in the volume of services requested by CORE's clients, could have a material adverse effect on CORE. See "Business-Clients and Marketing."

RISKS RELATED TO GROWTH STRATEGY. Part of CORE's strategy is to continue its internal growth and, as strategic opportunities arise in the managed disability services market, to pursue relationships with other companies in related lines of business. As a result, CORE is subject to certain growth-related risks, including the risks that it will be unable to retain personnel or acquire other resources necessary to service such growth adequately. Expenses arising from CORE's efforts to increase its market penetration may have a negative impact on operating results. In addition, suitable opportunities for strategic relationships or acquisitions may not arise or, if they do arise, the transactions contemplated thereby may not be completed. See "Business-Strategy."

UNCERTAINTY OF FUTURE PROFITABILITY. Although profitable in 1999, 1997 and 1996, CORE recorded net losses of $3,760,000 for 1998. CORE may not be able to maintain profitability on a quarterly or annual basis. Moreover, the level of profitability, if any, cannot be accurately predicted. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

EXPOSURE TO PROFESSIONAL LIABILITY. CORE, through its managed care services, makes recommendations regarding benefit plan coverage and work absence periods based upon judgments of the appropriateness of proposed medical treatment plans and length of absence. In certain instances CORE can determine or deny such coverage or absence periods. Consequently, CORE has and may in the future become subject to claims related to adverse medical consequences or for the costs of services denied and claims, such as malpractice, arising from the errors or omissions of health care professionals. A successful claim against CORE could have a material adverse effect on CORE's financial position and results of operations. Furthermore, claims against CORE, regardless of their merit or eventual outcome, may involve substantial defense costs. Procedures implemented by CORE to limit its liability may not be effective and litigation to which CORE is or may become subject may adversely affect its financial position or results of operations. CORE maintains professional liability insurance and such other coverages as CORE believes are reasonable in light of its experience to date. However, such insurance may not be sufficient to protect CORE from liability or may not continue to be available to CORE at reasonable cost or at all.

GOVERNMENT REGULATION; HEALTH CARE REFORM. The health care industry is subject to extensive federal and state regulation relating to licensure, conduct of operations and prices for services. A number of states, including several of those in which CORE transacts business, have extensive licensing and other regulatory requirements applicable to CORE's business, including utilization review and workers' compensation. These requirements include compliance with federal and state prohibitions on the offer or receipt of payment for patient referral or other items or services. CORE's clients, including insurance companies, are also subject to regulations which indirectly affect CORE. Regulation in the health care field is constantly evolving. CORE can not predict what additional government regulations, if any, may directly or indirectly affect its business. Although CORE believes it is in material compliance with applicable statutes, licensing requirements and regulations in those states in which it is subject to regulation, a revocation of or failure to obtain required licenses and governmental approvals, a failure to comply with applicable statutes or regulations or significant changes in regulations applicable to its clients could adversely affect CORE's business. See "Business-Government Regulation; Health Care Reform."

In addition to existing government health care regulation, there have been numerous initiatives at the federal and state levels, as well as by private third-party payers, for comprehensive reforms affecting the payment for and availability of health care services. CORE believes that such initiatives will continue during the foreseeable future. CORE can not predict what, if any, reform initiatives may be adopted, or what effect, if any, their adoption may have on CORE.

RELIANCE ON DATA PROCESSING CAPABILITIES. CORE's business in general, and its WorkAbility disability management program in particular, depends on the ability to continuously store, retrieve, process and manage data. Interruption of data processing capabilities for any extended length of time, loss of stored data, programming errors or other computer problems could have a material adverse effect on CORE's business.

14

COMPETITION. The markets in which CORE operates are highly competitive. In addition to other utilization management and disability management companies, CORE competes with insurance companies, third-party administrators and preferred provider organizations. Many of CORE's competitors are larger and have greater financial and other resources than CORE. Competitive factors in CORE's markets may have an adverse effect on CORE. See "Business-Competition."

DEPENDENCE ON KEY PERSONNEL. CORE's success will depend to a significant extent upon the skills of a number of executive officers and key employees. In addition, CORE's success will depend to an extent on its ability to recruit credentialed physicians for CORE's peer review activities. The future loss of the services of one or more key persons could adversely affect CORE.

POTENTIAL VOLATILITY OF STOCK PRICE. The market prices for CORE's Common Stock and the securities of certain other companies in the health care industry have historically been significantly volatile. The trading price of the Common Stock could continue to significantly fluctuate due to uncertainties regarding the businesses of CORE, announcements or actions by competitors, developments involving CORE's relationships with key clients, government regulation, fluctuations in quarterly results and other factors. These broad market fluctuations, as well as general economic conditions and the financial performance of CORE, may adversely affect the market price of CORE Common Stock. See "Price Range of Common Stock."
