ITEM 1.  BUSINESS

GENERAL

                  Collaborative Clinical Research, Inc. ("Collaborative" or the
"Company") is a multi-specialty Site Management Organization ("SMO") with an
international network comprised of over 540 clinical research sites ("Affiliated
Sites"). Each site is affiliated with the Company through a written agreement
which describes a cooperative relationship between the Company and the
Affiliated Site. The Network, with more than 3,700 clinical investigators,
provides rapid access to patients who can participate in clinical research
trials. Collaborative's customers ("Sponsors") for these trials are primarily
pharmaceutical and biotechnology companies and, to a lesser extent, contract
research organizations, ("CRO's").

         The Company and its Affiliated Sites assist Sponsors in conducting the
clinical research necessary to obtain regulatory approval for new drugs. In
addition, Collaborative provides Sponsors with an innovative and timely means of
selecting clinical research sites and managing clinical trials as part of the
pharmaceutical product development process. Collaborative provides its
Affiliated Sites with sales and marketing, project budgeting and contract
negotiation services. The Company also owns three clinical research sites.
Throughout its history, the Company has been involved in over 400 clinical
trials providing services to approximately 120 Sponsors.

         Founded in 1991 as an innovator of the SMO concept, Collaborative has
grown through a combination of internal expansion and strategic acquisition.
Collaborative acquired two companies in 1996, GFI Pharmaceutical Services, Inc.
("GFI") and WCE Clinical Evaluations ("WCE"). GFI conducts Phase I clinical
research at its 80 bed facility in Evansville, Indiana and Phase II through IV
clinical research at the Company's three owned clinical research sites. WCE's
services are directed primarily toward Over the Counter ("OTC") pharmaceutical
products, and include studies necessary to switch prescription drugs to OTC use,
label comprehension evaluations and consumer product testing.

         In 1996, Collaborative formed a wholly owned subsidiary, DataTRAK, Inc.
("DataTRAK"). In January 1998, DataTRAK purchased the software now known as
DataTRAK EDC(TM). This software is the foundation of the DataTRAK(R) process.
DataTRAK will provide certain electronic data management services to Sponsors
through use of its Electronic Data Capture ("EDC") technology and Quality Review
Center ("QRC") process. Use of the DataTRAK(R) process offers Sponsors the
potential to increase the efficiency, accuracy and timeliness of collection and
management of clinical research data and access to patients through DataTRAK
certified sites. The research sites used in this service may be Affiliated Sites
of Collaborative or sites selected by the Sponsor. The DataTRAK EDC(TM) software
and its earlier versions have supported more than 30 clinical studies in
Europe encompassing over 500 clinical research sites and 3,000 patients.

         In January 1998, the Company announced the termination of its
technology alliance agreement with ISSC, a unit of IBM Global Services. The
Company and IBM Global Services disagree on a number of issues concerning the
parties' financial responsibilities in connection with the termination of the
alliance, and have engaged in discussions concerning those matters. To date,
those discussions have not resulted in an acceptable resolution of these issues.
The Company does not believe that it has any continuing financial obligations to
IBM Global Services and, based on information known to date, does not believe
that additional expenditures associated with the termination of this alliance,
if any, will have a material adverse effect on the Company's results of
operations and financial condition. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition."

CLINICAL RESEARCH INDUSTRY OVERVIEW

         The clinical research industry is driven by regulatory requirements
that Sponsors adequately test new drugs and devices prior to marketing. The drug
development process has become more challenging, lengthy and expensive. In a
recent analysis covering three decades of pharmaceutical industry data, the
Tufts Center for the Study of Drug Development examined the time interval from
Investigational New Drug Application ("IND") to New Drug Application ("NDA")
approval. These approval times grew from 7.3 years in the period from 1963 to
1972, to 11.9 years from 1973 to 1982, and to 14.3 years from 1983 to 1992. The
estimated average cost of this process has also grown substantially.

         Competitive and cost-containment pressures are forcing the
pharmaceutical and biotechnology industries to become more efficient in
developing new drugs. To improve returns on research and development
investments, pharmaceutical and biotechnology companies are expanding their
product pipelines and attempting to shorten the product development timeline.

         In response to similar cost-containment pressures, many hospitals,
physicians, and other healthcare providers have added clinical research
capabilities as an additional revenue source. Clinical research allows
healthcare providers to extend their core competencies and capitalize on their
direct access to patients.

Industry Trends in Drug Development

Pipeline and Process Challenges
- -------------------------------

         Sponsors face many challenges in continuing to deliver an increasing
return on research and development expenditures. Lengthier drug development time
frames, increased drug development costs, margin pressures arising from emphasis
on cost-containment in healthcare, limited patent life, and competition from
generic drug companies, are forcing Sponsors to be as efficient and
cost-effective as possible in managing their clinical development processes.

         One result of these challenges is that Sponsors are targeting
simultaneous regulatory approvals in many countries to accelerate global time to
market. A second result is that product pipelines are expanding as promising new
compounds come from advanced drug discovery efforts, high throughput screening
techniques, and the development of genomic libraries. These efforts have placed
more drugs into the clinical development process, and have increased pressure on
Sponsors to develop products faster to maintain growth and continue to achieve
acceptable returns on research and development expenditures.

         Sponsors have attempted to create process efficiencies, control fixed
costs, and expand capacity by outsourcing certain clinical research activities.
The CROs are the most mature and established group used for outsourcing at this
time. The amount of clinical research that is outsourced varies by Sponsor,
however, the Company believes increases in outsourcing, including temporary
access to therapeutic focus and expertise to develop products across many
disease states, will continue.

Outsourcing
- -----------

         Under traditional outsourcing in clinical research, the Sponsor
subcontracts various aspects of a preclinical or clinical development program to
a service provider. Such services typically include: protocol development, site
selection, site contracting, project management, monitoring, data management,
investigational drug packaging, regulatory consulting, NDA preparation, and
post-approval and marketing services.

         The term outsourcing has not traditionally applied to the use of
clinical research sites, even though Sponsors generally do not own or operate
such sites. Clinical research contracts with investigator sites 



                                       2
<PAGE>   5


provide access to patients for a clinical trial. The Company provides access to
sites and patients, and believes that its services are viable to a Sponsor
regardless of whether a project is outsourced or managed internally by the
Sponsor.

Accelerating Clinical Development
- ---------------------------------

         As drug development pipelines have grown, a substantially greater
number of compounds are scheduled for development today versus a few years ago.
Most Sponsors are facing critical strategic decisions to develop this influx of
new compounds efficiently. Outsourcing to service providers has increased
capacity to conduct these new clinical trials. However, outsourcing, per se,
does not appear to have accelerated the drug development process.

         One of Collaborative's goals is to assist Sponsors in starting and
finishing their clinical trials on a more timely basis. The Company aims to
achieve this goal through its rapid activation of Affiliated Sites at the start
of a clinical trial, and by using the DataTRAK(R) process to expedite the data
collection and reporting process during a clinical trial.

BUSINESS STRATEGY

         The Company's strategy is to help Sponsors accelerate the process of
obtaining regulatory approval for new drugs. Collaborative will implement this
strategy by providing rapid access to patients through a clinical research
network, and by automating the collection of clinical trial data through a
standardized technology platform.

Utilization of the Affiliated Site Network
- ------------------------------------------

         The Company's Network of Affiliated Sites provides a clinical research
model that responds to Sponsors' needs to bring new products to market faster.
The Network improves time-efficiency in the clinical research process primarily
in site identification and contracting. This provides Sponsors with the
opportunity to begin clinical research sooner, thereby shortening this phase of
the new drug development process.

         Collaborative's network approach serves the independent research site
by delivering incremental clinical research revenue, by marketing the
capabilities of all Affiliated Sites and by negotiating one contract for all
Affiliated Sites participating in any one clinical trial. Affiliated Sites are
provided with a number of clinical research opportunities involving a wide
variety of therapeutic areas.

Expansion and Targeting of the Affiliated Site Network
- ------------------------------------------------------

         In targeting potential additions to the Affiliated Site Network, the
Company considers several factors, including clinical trial experience,
enrollment performance and overall work quality. In order to focus better on
projected drug development pipelines of Sponsors, Collaborative will refine its
Network into groups based on site-specific therapeutic specialties. Proficiency
in these identified specialty areas has become an additional consideration for
future site affiliations.

Development of the DataTRAK(R) Process
- --------------------------------------

         DataTRAK is a service business that offers a process for electronic
data collection and clinical trial data management capabilities across a network
of sites. DataTRAK's objective is to improve the traditional process of
collecting clinical research and noninterventional health care data by providing
cleaner data faster than what is available in a paper environment. In order to
implement this strategy, the Company acquired the software technology now known
as DataTRAK EDC(TM) in January 1998. This 


                                       3
<PAGE>   6



software has been validated by several European Sponsors, and has been used in
over 30 clinical trials at 500 sites involving more than 3,000 patients.

         Currently, clinical research associates ("CRAs") visit research sites
to review data manually entered on the case report form ("CRF") for accuracy and
integrity. During these physical visits, each CRF page is reviewed by the CRA.
These monitoring visits may last several days, and corrections to the CRFs are
frequently required before delivery to the Sponsor. Several weeks or even months
of data must be reviewed during each monitoring visit. At the completion of a
monitoring visit, the CRF pages are delivered to a central location where the
data is then entered into a database for statistical compilation. Using this
traditional method of data collection and quality control, the time duration
from patient visit to delivery of clean data to the Sponsor can range from six
to twelve months. Such delays are significant because errors or trends may not
be detected until long after the interaction between patient and investigator.
The Company believes the drug development process can be accelerated by
automating these procedures.

         DataTRAK has two strategies. First is to place systems and software at
Collaborative's Network and Sponsor selected sites for long-term use in clinical
trials. Second is to provide any Sponsor, CRO, SMO or competing network the
opportunity to use the DataTRAK(R) process as a competitive advantage for their
clients. In this manner, the DataTRAK(R) process can develop into a standardized
electronic data capture platform for the clinical trial industry.

         Clinical trial data will be collected on electronic CRFs across a
network of sites and routed across a secure communications environment to
DataTRAK's QRC. The QRC largely replaces traditional monitoring. Once the CRF
data has been reviewed to correct errors it is integrated directly into a
Sponsor's database in Sponsor specified formats.

THE AFFILIATED SITE NETWORK

         Since 1991, the Company has developed a network of more than 540
Affiliated Sites and today provides Sponsors with rapid access to over 3,700
principal investigators in a wide variety of therapeutic areas. Affiliated Sites
range from group practices with individual investigators to integrated health
care delivery systems with hundreds of investigators, and include academic
medical centers, community hospitals, outpatient treatment centers, research
centers, managed care organizations and physician practice groups. Regardless of
its size, each member of the Network is considered a single Affiliated Site.

         The Company's Network includes investigators experienced in infectious
disease and HIV/AIDS, orthopedics, cardiology, hematology/oncology, pulmonary,
endocrinology, gastroenterology/metabolism, and neurology, among other medical
specialties. Each Affiliated Site is a party to an affiliation agreement with
the Company, which defines the duties and responsibilities of each party. These
relationships produce expeditious access for Sponsors to qualified clinical
investigators and evaluable patients. Although Affiliated Sites remain free to
solicit and accept clinical research contracts directly from Sponsors, they are
prohibited from affiliating with another network. At the request of Sponsors,
the Company uses research sites outside of its Affiliated Site Network. For
example, Sponsors may request that the Company use research sites outside the
Affiliated Site Network in large, multi-site trials or to include trial
investigators of national standing in a particular therapeutic area or those
whom the Sponsor has worked with in the past. The Company regularly updates its
demographic database on each Affiliated Site.

SERVICES

         The Company's core business is to provide site selection and project
management services for clinical trial programs in many therapeutic areas. The
Company also performs clinical research at its three owned sites. The Company
assists Sponsors in identifying and recruiting investigators, initiating
clinical trials at sites and managing clinical trials. On occasion, the Company
also provides other clinical trial


                                       4
<PAGE>   7


services to meet specific Sponsor needs. The Company has managed trials which
range in size from single site trials involving fewer than ten patients to a 300
site trial involving 3,000 patients.

Site Selection Services

         The Company identifies and recruits clinical research sites and
clinical investigators to participate in a clinical trial on behalf of a
Sponsor. A Sponsor may utilize certain site selection services, such as the
Company's abstract and survey to determine the specific interest of research
sites in a particular trial and anticipated evaluable patient population. The
Sponsor can use the results of the abstract and survey to determine the number
of sites required for a clinical trial and to predict whether the Company can
deliver the expected results.

Company-Owned Clinical Research Facilities

         The Company's GFI subsidiary performs clinical research and provides
other clinical research services through its three research facilities for
conducting Phase II through Phase IV research (one facility also includes an 80
bed Phase I clinical research unit). Phase I clinical research is substantially
more specialized and limited than other phases of the research process because
hospital or clinic beds must be available for extended stays in a sequestered
environment.

Clinical Trial Management Services

         The Company provides a variety of clinical trial management services,
whether clinical trials are performed at Affiliated Sites or owned research
facilities. These services include pre-study and research site activation
services, patient tracking services and clinical trial management. Additional
services include coordination of investigator meetings, the Institutional Review
Board ("IRB") approval process and other procedures that must be performed prior
to enrollment of patients into a study, and assistance in patient recruitment
and enrollment.

DataTRAK Services

         DataTRAK will provide EDC services to Sponsors that will facilitate
rapid collection of clinical trial data. As a service provider, DataTRAK will
design electronic CRF's with validation routines and edit checks and train
appropriate investigative sites and Sponsors on the use of the electronic data
capture software and associated services. All clinical data collected from the
various sites for a given clinical trial will be reviewed for accuracy by
DataTRAK's QRC. DataTRAK will initiate a Site Certification Program, designed to
train sites on the DataTRAK(R) process.

OTC Services

         The Company's WCE subsidiary provides contract research services on
pharmaceuticals, especially when being switched from prescription to OTC
products, and on medical devices, foods, and other products intended for broad
consumption. The contract research services provided by WCE include consultation
on and performance of studies necessary to switch prescription drugs to OTC
products, label comprehension evaluations, and consumer product testing.

CUSTOMERS AND MARKETING

         Collaborative has served many leading pharmaceutical and biotechnology
companies and CRO's. Collaborative's business development strategy focuses on
marketing its clinical research expertise, as well as that of its Affiliated
Sites, its ability to gain timely access to patients with specific medical
conditions and its ability to rapidly and efficiently start up and manage
multi-site clinical research trials for Sponsors. Collaborative's sales staff
generally has scientific or pharmaceutical backgrounds and are located


                                       5
<PAGE>   8



regionally throughout the United States. They are expected to provide Sponsors
with consultative selling support regarding Collaborative's capabilities and
services in the clinical research process. The Company concentrates a majority
of its marketing resources on direct selling to Sponsors. It also selectively
participates in scientific and medical meetings to promote its services and
occasionally uses direct mail and journal advertisements to build awareness of
its capabilities. DataTRAK markets its services through its United States and
European staff and through the Company's sales and marketing staff.

         During each of the three years in the period ended December 31, 1997,
sales to companies in the pharmaceutical industry accounted for more than 69% of
the Company's revenue. During 1995 and 1996, respectively, sales to Merck & Co.,
Inc. accounted for approximately 76% and 22% of the Company's revenue. Also
during 1996, sales to Dey Laboratories accounted for 31% of the Company's total
revenue. Other customers in the pharmaceutical industry have from time to time
accounted for more than 10% of the Company's annual revenue. Bristol Myers
Squibb and Pharmacia & Upjohn each accounted for more than 10% of revenue during
1997. The extent to which the Company relies on sales to one customer varies
from period to period, depending upon the timing of new clinical research
contracts, the relationship between the Affiliated Sites' therapeutic expertise
and a Sponsor's specific therapeutic needs, the Company's ability to generate
new business, the timing and size of clinical trials, and other factors. Due to
the consolidation in the pharmaceutical industry and the Company's marketing
focus on the major pharmaceutical and biotechnology companies, management
expects continued concentration in its revenue in the future. It is not unusual
for companies involved in the placement and administration of clinical trials to
derive more than 10% of their revenue from a single customer. However, the
Company's small revenue base makes it more dependent on major customers than
many of the larger participants in the clinical research industry. The loss of
business from a significant customer could materially and adversely effect the
Company's revenue.

CONTRACTING AND BACKLOG

         The Company's contracts provide a fixed price for each component or
service delivered. The ultimate contract value depends on such variables as the
number of research sites selected, patients enrolled and other services required
by the Sponsor. Generally, the Company's contracts range in duration from
several months to several years. As services are performed over the life of the
contract, revenue is earned under the percentage of completion method utilizing
units of delivery. Costs associated with contract revenue are recognized as
incurred. Cash flows vary with each contract, although generally a portion of
the contract fee is paid at the time the trial begins, with the balance paid as
pre-determined contract milestones are satisfied.

         Generally, Sponsors may terminate a contract with the Company with or
without cause. In the event of termination, the Company is entitled to payment
for all work performed through the date of notice of termination and for costs
associated with termination of the study. Clinical trials may be terminated for
several reasons, including unexpected results or adverse patient reactions to
the drug, inadequate patient enrollment or investigator recruitment,
manufacturing problems resulting in shortages of the drug, and decisions by the
Sponsor to de-emphasize or terminate either a particular trial or drug. A
Sponsor's decision to terminate a sizable trial in which the Company
participates could have a material adverse effect on the Company's backlog,
future revenue and profitability.

         Backlog consists of anticipated revenue from letters of intent and
signed contracts yet to be completed. In certain cases, the Company will work on
a project prior to finalizing a letter of intent or contract. Such projects are
excluded from backlog until a definitive letter of intent or contract is
executed.

         The Company's backlog is not necessarily a meaningful predictor of
future results. Contracts included in backlog are subject to termination or
delay at any time. There can be no assurance that the Company will realize
revenue from backlog or as to the amount of backlog that will be converted to
revenue within any fiscal period. Delayed contracts remain in the Company's
backlog until canceled. As 


                                       6

of December 31, 1996 and 1997, the Company's backlog was $22.5 million and $25.9
million, respectively.

COMPETITION

         The clinical research industry is highly fragmented and comprised of
several large, full-service CROs and many small CROs and limited service
providers. The major competitors in the industry include the research
departments of pharmaceutical companies, CROs and other SMOs. The Company
competes in this market on the basis of its ability to provide rapid access to
high-quality clinical investigators and patients through its Network of
Affiliated Sites. In addition, through DataTRAK, the Company will integrate
information technology to provide EDC and remote monitoring through its QRC in
order to further accelerate the clinical trial process. Many of the Company's
competitors have substantially greater financial and other resources than the
Company, and there can be no assurance of the Company's ability to continue to
compete effectively with these larger competitors. To the extent the Company's
approach to the conduct of clinical trials continues to gain acceptance in the
market, there can be no assurance that these larger competitors will not develop
their own networks of research sites, nor as to the effect of such competing
networks on the Company's operations. The Company may also face competition from
other networks of research sites in the recruitment of potential Affiliated
Sites.

         Further, the electronic data capture market, which is still developing,
is also highly fragmented. The major competitors include EDC software vendors,
clinical trial data service companies and in-house development efforts within
large pharmaceutical companies. There can be no assurance that the Company will
be able to capture or establish the market presence necessary to effectively
compete in this emerging sector of the clinical research industry.

REGULATORY MATTERS

Government Regulation

         The clinical investigation of new pharmaceutical and biotechnology
products is highly regulated. The purpose of these regulations is to assure that
products are safe and effective before broad public use. The Food and Drug
Administration ("FDA") has promulgated regulations and guidelines pertaining to
applications to initiate trials of new compounds, approval and conduct of
studies, report and record retention, informed consent, applications for
approval of new compounds and post-marketing requirements. Under FDA
regulations, companies providing clinical research services that assume the
obligations of a drug Sponsor are required to comply with applicable FDA
regulations and are subject to regulatory action for failure to comply with such
regulations. The historical trend has been toward increased regulation by the
FDA; however, recent initiatives have been undertaken by the FDA to streamline
the agency's internal review processes.

         The services provided by the Company are ultimately subject to FDA
regulation and to appropriate regulatory authorities in other countries where
the Company offers its services. The level of regulation in other countries
generally has been less comprehensive than that present in the United States.
However, through the efforts of the International Committee on Harmonization,
the governing regulations of participating nations are moving toward
equivalence. Depending on the nature of services provided with respect to a
particular research trial, the Company may be required to comply with FDA
regulations governing such activities as selecting investigators, obtaining
documentation from investigators, verifying that patient informed consent is
obtained, monitoring the validity and accuracy of data, verifying drug
accountability and instructing investigators to maintain records and reports.
The Company must also maintain records for each study for specified periods for
inspection by the study Sponsor and the FDA. If FDA audits indicate that the
Company has failed to adequately comply with federal regulations and guidelines,
it could have a material adverse effect on the Company. In addition, the failure
of the Company to comply with applicable regulations could result in termination
of on-going research or the 


                                       7
<PAGE>   10



disqualification of data, either of which could also have a material adverse
effect on the Company's results of operations, financial condition and
reputation.

The Drug Development and Approval Process

         All drugs proposed to be marketed in the United States must undergo an
extensive development and approval process. Pre-clinical testing is the first
stage in this process. During the pre-clinical stage, a new compound is tested
in vitro and in animals over a one to three year period in order to obtain
information concerning the basic biological activity and safety of the drug. If
the results of pre-clinical studies are satisfactory, the Sponsor files an IND
with the FDA before beginning human testing. In order to receive IND status, the
Sponsor must provide the FDA with manufacturing data, preclinical test results,
information concerning the uses of the drug in other countries or in the United
States for other purposes and a plan for conducting clinical trials. The design
of each clinical trial, or its "protocol," is an essential component of the drug
development effort. Each protocol must anticipate the nature of the data and
results that the FDA will require before approving the drug.

         In the absence of any comments from the FDA on the IND, a Sponsor may
begin clinical trials on human subjects 30 days after the IND is filed. Clinical
trials often represent the most expensive and time consuming part of the drug
development process. The trial process usually starts on a small scale with
trials intended to assess safety, and then expands to larger trials in order to
test a compound's efficacy. There are four phases of clinical testing, with
multiple trials generally conducted within each phase.

         Phase I testing typically consists of specialized studies designed to
         acquire safety and dosing information on a new compound. In these
         studies, the drug is tested on approximately 20 to 80 individuals and
         data is gathered concerning toxicity, absorption, metabolism and other
         pharmacological actions. Each individual study lasts from a period of
         days to several weeks, and the phase itself typically lasts from six
         months to one year.

         Phase II testing typically consists of studies in approximately 100 to
         200 patients who suffer from the targeted disease or condition. Phase
         II trials focus on obtaining information on the drug's effectiveness
         and dose-response relationship. Because these trials gather early
         evidence of a compound's efficacy, their results are often pivotal to a
         Sponsor's decision concerning whether to proceed to larger trials.
         These trials typically last one to two years.

         Phase III testing typically consists of large, multi-center trials
         involving hundreds to thousands of patients. Phase III trials are
         intended to collect efficacy and safety information on a large scale.
         The collection of such data is most critical in Phase III, because the
         data developed during these trials will have a significant influence on
         the labeling aspects of the new drug. At least one Phase III trial is
         required to be performed within the United States on any compound
         before it will be approved by the FDA. These trials typically last two
         to three years.

         Phase IV studies are frequently required by the FDA as a condition to
         granting marketing approval. After a drug is approved for marketing,
         the FDA will often require Sponsors to conduct additional clinical
         trials to monitor long-term risks and benefits, alternative dosage
         levels or evaluate safety and efficacy in targeted patient populations.
         These studies are usually less data intensive than those conducted in
         other phases of clinical research, but may involve hundreds to
         thousands of patients and can last for several years.

         After a new compound has successfully completed the first three phases
of the clinical trial process, a NDA is submitted to the FDA. The NDA is a
comprehensive filing that includes the results of all pre-clinical and clinical
studies, with the majority of its clinical data derived from Phase II and Phase
III trials. In addition, the NDA contains information about the drug's
composition and the Sponsor's plans for producing, packaging and labeling the
product. The FDA's review process for an NDA can take anywhere from a few
months, for drugs related to life threatening conditions, to many years, with
the average review 


                                       8
<PAGE>   11


lasting more than two and one-half years. Drugs that successfully complete this
review may be marketed in the United States, subject to such conditions as the
FDA may specify. As a result of increasing public pressure to allow new drugs to
reach the market more quickly, the FDA has increased its reliance on Phase IV
studies. In some instances, the FDA has granted conditional approval to
potentially lifesaving drugs or those for previously untreatable conditions in
order to permit marketing while Phase IV studies are conducted.

         When results from Phase II or Phase III show special promise in the
treatment of a serious condition for which existing therapeutic options are
limited or of minimal value, the FDA may allow the manufacturer to make the new
drug available to a larger number of patients through the regulated mechanism of
a Treatment Investigational New Drug ("TIND"). Although less scientifically
rigorous than a controlled clinical trial, a TIND trial may enroll and collect a
substantial amount of data from tens of thousands of patients.

         The pre-clinical and clinical testing and approval processes for
biotechnology products are substantially similar to those applicable to drugs,
except that the results of clinical trials are submitted in the form of a
Product License Application rather than an NDA. In many cases, medical device
products are also subject to extensive pre-clinical and clinical testing
requirements.

FDA Guidance for Industry:  Computerized Systems Used in Clinical Trials

         On June 18, 1997, the FDA issued draft guidelines, on the use of
computer systems in clinical trials, for review and comment by the public and
affected industries. The FDA draft includes guidelines related to standard
operating procedures, data entry, system design, security, system dependability
and controls, personnel training, records inspection, and certification of
electronic signatures. Based on its review of these draft guidelines, the
Company believes the DataTRAK(R) process for electronic data capture and
management is consistent with this draft guidance. Because the FDA's development
of this guidance is still in the early stages, the Company will continue to
monitor this guidance to ensure compliance.

POTENTIAL LIABILITY AND INSURANCE

         Clinical trials involve the testing of approved and non-approved drugs
on human beings. This testing carries with it a significant risk of liability
for personal injury or death to participants resulting from an adverse reaction
to, or improper administration of, the trial drug. Many clinical trial
participants are seriously ill and are at great risk of further illness or death
as a result of factors other than their participation in the trial. The Company
participates with Sponsors in the site selection process, and contracts on
behalf of Sponsors with physicians who render professional services, including
administering the drugs being tested, to participants in these trials. Company
personnel and subcontractors also render professional services to participants
in trials, and are materially involved in the patient treatment process.
Consequently, the Company may be subject to claims in the event of personal
injury or death of persons participating in clinical trials and arising from
professional malpractice of physicians with whom it has contracted and its own
employees. To date, the Company has not received any claims resulting from
either the testing of new drugs or professional malpractice.

         The Company believes that the risk of liability associated with
clinical trials is mitigated by various regulatory requirements, including the
role of IRB's. An IRB is an independent committee that includes medical and
non-medical personnel and is obligated to protect the interests of patients
enrolled in the trial. The FDA requires each human clinical trial to be reviewed
and approved by the IRB at each research site After the trial begins, the IRB
monitors the protocol and the measures designed to protect patients, such as the
requirement to obtain informed consent. In addition, regulations governing the
conduct of clinical trials and the protection of human subjects place
responsibility for proper study conduct 



                                       9
<PAGE>   12



and subject protection directly on the principal investigator at each location
where a study is performed. At its owned research facilities, the Company has
assumed the duties and liabilities of a principal investigator.

         In order to reduce its exposure to liability, the Company generally
obtains indemnification from Sponsors and, in some cases, from investigators and
Affiliated Sites contracted by the Company. The Affiliated Sites' agreement
obligates the Company to pursue contracts only with Sponsors that provide
indemnification for adverse outcomes, and that allow such indemnification rights
to pass through to the Affiliated Sites and investigators. These indemnity
rights do not protect the Company against certain of its own actions, such as
negligence or misconduct. Furthermore, these indemnities are contractual
arrangements that are subject to negotiation, and the terms and scope of such
indemnities may vary. In order for such indemnification to be valid, the Company
and its employees and agents must act within the bounds of specific procedural
requirements governing the conduct of the clinical trial. Since the value of the
indemnification depends on the financial viability of the indemnifying party,
there can be no assurance that the Company will be able to rely on such
indemnification in each instance of potential liability. The financial position
of the Company could be materially adversely affected if the Company was forced
to undertake the defense of, or was found financially responsible for, claims
based upon the foregoing or related risks.

         The Company maintains an errors and omissions professional liability
insurance policy in amounts it believes to be sufficient. However, there can be
no assurance that this coverage will be adequate, or that insurance coverage
will continue to be available to the Company.

PATENTS AND TRADEMARKS

         The Company holds registered service marks incorporating the
Collaborative Clinical Research logo, the DataTRAK(R) process, and various
DataTRAK trademarks, including the DataTRAK EDC(TM) software. Through
acquisitions the Company holds additional registered service marks. The DataTRAK
EDC(TM) software is the foundation of the DataTRAK(R) process. The Company does
not own any patents. The Company believes that its ability to attract and retain
highly-skilled employees and manage the growth of its business are more
important to its performance than any intellectual property rights that it has
purchased or developed to date. The Company anticipates that DataTRAK will
constitute a material portion of its business in the future, and the
DataTRAK(R) process will become an important component of the Company's 
business.

INFORMATION TECHNOLOGY

         Information systems are an integral part of the services the Company
provides. The Company is reviewing its systems to assess the Year 2000 issue.
Management believes that neither the costs nor expenses of the Year 2000 issue
will be material to the Company. The Company's services are also dependent on
the systems used by its Affiliated Sites, Sponsors, and other customers and
vendors. Year 2000 issues encountered by these companies could have a material
adverse effect on the Company.

EMPLOYEES

         As of January 31, 1998, the Company had approximately 150 full-time
employees, of whom eight had executive and managerial responsibilities. None of
the Company's employees are represented by a union. The Company considers
relations with its employees to be satisfactory.

          The Company's growth continues to place significant demands on its
management resources. The success of the Company's business is dependent on the
services of its senior management team, which changed substantially in 1997. The
Company has employment agreements with all but one of its executive officers.
The loss of the services of any of its executive officers could have a material
adverse effect on the Company. To address these risks, the Company must, among
other things, continue to attract, retain and 


                                       10
<PAGE>   13



motivate qualified personnel. There can be no assurance that the Company will be
successful in addressing such risks.

ITEM 2.  PROPERTIES

         The Company presently maintains its executive offices in approximately
14,000 square feet of space in Cleveland, Ohio pursuant to two leases with
unaffiliated third parties. The Company leases approximately 32,000 square feet
of office and medical space in Evansville, Indiana. This facility houses, among
other things, an 80 bed in-patient Phase I research facility. The Company also
leases property in two additional states and the United Kingdom, most of which
is used to conduct or manage clinical research projects. Collaborative believes
that its facilities are adequate for its operations and suitable additional
space will be available when needed.

ITEM 3.  LEGAL PROCEEDINGS

         From time to time, the Company is a party to various lawsuits arising
in the ordinary course of business. The Company does not believe that the
outcome of such litigation will have a material adverse effect on its results of
operations or financial condition.

         On September 5, 1997, a summons and complaint was filed by the Company
in the Netherlands against the shareholders of U-Gene Research B.V. for breach
of contract. The claim is for money damages for costs incurred and liquidated
damages related to an aborted acquisition of U-Gene Research B.V. To date,
responsive pleading by the defendants is pending.

         On July 18, 1997, two former executive officers of the Company claimed
that their employment agreements were violated by the Company and, by letter,
each demanded payment from the Company of an amount equal to one year's annual
salary. The Company believes their claims are without merit, and is pursuing the
non-compete provisions of the employment contracts. Under the terms of their
employment agreements, the dispute will be resolved through arbitration. An
arbitration hearing was held on March 7, 1998 but to date, the arbitrator's
ruling has not been announced.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted to a vote of security holders during the
fourth quarter of the fiscal year ended December 31, 1997.

         On February 27, 1998, the last sale price of the Common Shares as
reported by Nasdaq was $4.38 per share. As of February 27, 1998, there were 98
holders of record and approximately 1,100 beneficial holders of the Common
Shares.

         The Company has never declared or paid cash dividends on its Common
Shares. The Company currently intends to retain any earnings for use in its
business and therefore does not anticipate paying any dividends in the
foreseeable future. Any determination to pay cash dividends in the future will
be at the discretion of the Board of Directors after taking into account various
factors, including the Company's financial condition, results of operations,
current and anticipated cash needs and plans for expansion.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND 
         FINANCIAL CONDITION

GENERAL

         The Company is an SMO managing a clinical research network comprised of
over 540 Affiliated Sites. Collaborative also manages three owned clinical
research sites. Collaborative's revenue is derived by providing Sponsors with an
innovative, timely, cost effective and low risk means of selecting clinical
research sites and managing clinical trials as part of the pharmaceutical
product development process.

         Since commencing operations in 1991, Collaborative has grown through a
combination of internal expansion and strategic acquisitions. Collaborative
acquired two companies in 1996, GFI and WCE. GFI conducts Phase I through IV
clinical research at the Company's three owned clinical research sites. WCE's
services include studies necessary to switch prescription drugs to OTC products,
label comprehension 



                                       14
<PAGE>   17


evaluations and consumer product testing. Both acquisitions have been accounted
for under the purchase method of accounting, and the consolidated results of
operations include the results of operations of both businesses from their
respective acquisition dates. After allocating purchase price to the fair value
of the net assets acquired, the Company recorded approximately $8.4 million of
goodwill in connection with the acquisitions. The Company amortizes goodwill
using the straight-line method over a period of 20 years.

         The Company's wholly owned subsidiary, DataTRAK, was formed in 1996.
DataTRAK will provide certain electronic data management services, through its
EDC software and QRC, to improve quality, efficiency, and timeliness of the
clinical research process.


         The Company's backlog at December 31, 1997 was $25.9 million, as
compared to backlog of $22.5 million at December 31, 1996. Backlog is composed
of a number of contracts, each with a different term and duration. As is
customary, these contracts are subject to modification and/or possible
cancellation. Therefore, the amount of backlog is not necessarily indicative of
the Company's future quarterly or annual revenues. The Company has taken several
steps to reorganize its sales and operating structure, however its future
financial performance continues to depend on its success in bringing in new
business and converting backlog into revenue. To that end, management expects
its financial performance in the first half of 1998 to continue to reflect the
weaknesses experienced in the second half of 1997, but believes the remainder of
the year will begin to evidence a turn-around in the Company's business.


         The Company's clinical research service contracts generally have terms
ranging from several months to several years. A portion of the contract fee is
generally payable upon execution of the contract, with the balance payable in
installments over the life of the contract. Revenue and related direct costs are
recognized as specific contract terms are fulfilled under the percentage of
completion method utilizing units of delivery. The Company's contracts are
broken down into discrete units of deliverable services for which a fixed fee
for each unit is established. Pass-through costs that are paid directly by the
Company's Sponsors, and for which the Company does not bear the risk of economic
loss, are excluded from revenue. These costs can include investigator meeting
fees, IRB fees and travel costs. The termination of a contract results in no
material adjustments to revenue or direct costs previously recognized, and the
Company is entitled to payment for all work performed through the date of notice
of termination and all costs associated with termination of a study.

         The Company's contracts generally may be terminated by the Sponsor with
or without cause. Some of the reasons clinical trials may be terminated include
unexpected results or adverse patient reactions to the drug, inadequate patient
enrollment or investigator recruitment, manufacturing problems resulting in
shortages of the drug or decisions by the Sponsor to de-emphasize or terminate a
particular trial or development efforts on a particular drug. Depending on the
size of the trial, a Sponsor's decision to terminate or delay the trial could
have a material adverse effect on the Company's backlog, future revenue and
profitability.

         The Company's quarterly results can fluctuate as a result of a number
of factors, including success in attracting new business, the size and duration
of the clinical trials in which the Company and members of its Network of
Affiliated Sites participate, the timing of Sponsor decisions to conduct new
clinical trials or to cancel or delay ongoing trials, the impact of acquisitions
made by the Company and other factors, many of which are beyond the Company's
control.

- --------------

Year Ended December 31, 1997 Compared with Year Ended December 31, 1996

         Revenue decreased by $8.4 million, or 32.7%, from $25.7 million in 1996
to $17.3 million in 1997. The decrease was the result of a $12.8 million decline
in revenue from clinical trials conducted within the Company's Network of
Affiliated Sites, offset, in part, by the $4.4 million increase in revenue
attributable to operations acquired in 1996. The low level of revenue generated
by the Affiliated Sites was the result of the Company's inability to attract
sufficient new business and convert existing backlog into revenue during 1997.
Management has taken actions that it believes will result in growth in the
Company's level of backlog during 1998.


         Direct costs include compensation and related fringe benefits for
non-administrative employees (including those at Company-owned research
facilities) and other expenses directly related to contracts, which can be
subcontracted to the Affiliated Sites and other vendors. These costs decreased
by $5.4 million, or 30.0%, from $18.0 million in 1996 to $12.6 million in 1997.
Direct costs increased as a percentage of revenue from 69.9% in 1996 to 72.9% in
1997. Of the $5.4 million decrease, $9.0 million was caused by the decline in
revenue generated by the Affiliated Sites, which was partially offset by an
increase of $3.6 million due to the GFI and WCE acquisitions. The increase in
direct cost percentage was the result of the Company's low level of revenue and
its subsequent inability to leverage fixed costs.


         Selling, general and administrative expenses include all administrative
personnel costs, business and Affiliated Site development costs, and all other
expenses not directly chargeable to a specific contract. Selling, general and
administrative expenses increased by $3.9 million, or 63.9%, from $6.1 million
in 1996 to $10.0 million in 1997. Of the $3.9 million increase, approximately
$3.3 million reflects normal ongoing expenses, including $1.0 million incurred
at acquired research facilities and $1.2 million associated with DataTRAK. The
$3.9 million increase also includes approximately $600,000 of expenses related
to terminated negotiations for potential acquisitions. As a percentage of
revenue, selling, general and administrative expenses increased from 23.9% in
1996 to 57.8% in 1997. The increase in selling, general and administrative
expenses as a percentage of revenue reflects the lower absorption of fixed
operating costs resulting from decreased revenues, as well as the impact of
additional expenses incurred to support the Company's efforts to rebuild sales
and backlog, and its strategic initiatives.


                                       16
<PAGE>   19



         Special items include charges of $3.0 million for costs associated with
exiting certain Company activities. The charges were recorded in the fourth
quarter of 1997. These charges relate to changes in DataTRAK's business
including the write off of software and licenses, and changes in other parts of
the Company's business, including the disposal of certain medical equipment,
computer equipment, software and licenses, and the closing of a leased facility.

         Depreciation and amortization expense increased by $394,000 from
$606,000 in 1996 to $1.0 million in 1997. Of the $394,000 increase, $57,000
resulted from the depreciation of assets acquired with GFI and WCE, $133,000
resulted from the amortization of goodwill and $204,000 resulted from increased
capital expenditures.

         Other income increased from $1.0 million in 1996 to $1.9 million in
1997. This was the result of a $791,000 increase in interest income on invested
cash (primarily the proceeds of the Company's initial public offering), and a
$93,000 decrease in interest expense. Interest expense for 1996 was related the
issuance of notes payable to the former shareholders of GFI, and borrowings
against the Company's line of credit. Also, there was a $33,000 increase in the
Company's share of Health Research Innovations L.L.C's. ("HRI") net loss for the
twelve months ended December 31, 1997. The HRI joint venture, between the
Company and Pharmaceutical Marketing Services, Inc., was terminated during the
second quarter of 1997.

         As a result of the Company's net operating loss for the year ended
December 31, 1997, a $198,000 federal income tax benefit has been recorded at
December 31, 1997. This benefit represents the refund the Company is to receive
from its net operating loss carryback for federal income tax purposes. At
December 31, 1997, the Company has a net operating loss carryforward of
approximately $5.0 million which will expire in the year 2012. The Company's
federal tax benefit is offset by $140,000 of state income taxes for 1997.

Year Ended December 31, 1996 Compared with Year Ended December 31, 1995


         Revenue increased by $15.3 million, or 147.1%, from $10.4 million in
1995 to $25.7 million in 1996. Approximately $6.7 million of the increase was a
result of the GFI and WCE acquisitions. The remaining $8.6 million of the
increase was due to the number and size of the Company's new and ongoing
clinical trials primarily conducted at its Affiliated Sites. Approximately $7.6
million of the $8.6 million related to a full service clinical trial which began
in the fourth quarter of 1995. On a pro forma basis, giving effect to the GFI
and WCE acquisitions as if they had occurred on January 1, 1995, pro forma
revenue for 1996 of $28.8 million would have increased by 45% compared to 1995
pro forma revenue of $19.9 million.

         Direct costs increased by $9.5 million, or 111.8%, from $8.5 million in
1995 to $18.0 million in 1996. Direct costs decreased as a percentage of revenue
from 81.2% in 1995 to 69.9% in 1996. Of the $9.5 million increase, $4.0 million
was due to the acquisitions of GFI and WCE, and $5.5 million was due to the
number and size of Collaborative's new and ongoing clinical trials. Direct costs
for Collaborative's ongoing and new clinical trials, primarily conducted at the
Company's Affiliated Sites, decreased from 81.2% to 73.5% as a percentage of
revenue for 1995 and 1996, respectively. This reflects the effects of pricing
changes implemented by the Company during the second half of 1995 intended to
increase prices for certain services and include charges for certain
administrative contract costs that had previously been absorbed. As a percentage
of revenue, Collaborative's higher direct costs at its Affiliated Sites were
offset by the GFI and WCE subsidiaries' lower direct costs.

         Selling, general and administrative expenses increased by $3.3 million,
or 117.9%, from $2.8 million in 1995 to $6.1 million in 1996. Of the $3.3
million increase, $1.9 million reflects expenses associated with GFI and WCE's
operations and the remainder was due to the Company's internal growth. As a
percentage of revenue, selling, general and administrative expenses decreased
from 26.5% in 1995 to 


                                       17
<PAGE>   20



23.9% in 1996. The decrease in selling, general and administrative expenses as a
percentage of revenue reflects improved absorption of fixed costs resulting from
the increase in the Company's revenue.


         Depreciation and amortization expense increased by $544,000 from
$62,000 in 1995 to $606,000 in 1996. Of the $544,000 increase, $199,000 resulted
from the depreciation of assets acquired with the acquisitions of GFI and WCE,
$288,000 resulted from the amortization of goodwill resulting from the
acquisitions and $57,000 resulted from increased capital expenditures.


         Other income increased from $117,000 in 1995 to $1.0 million in 1996.
This was the result of a $924,000 increase in interest income on invested cash
(primarily the proceeds of the Company's initial public offering), offset by a
$93,000 increase in interest expense due to the issuance of notes payable to the
former shareholders of GFI, and borrowings against the Company's line of credit.
Also, there was a $90,000 decrease in the Company's share of HRI's net loss for
the twelve months ended December 31, 1996.


         As a result of the Company's net operating loss carryforwards of $1.4
million for federal income tax purposes, the Company's effective tax rate for
1996 was 19% of pre-tax income. This effective tax rate is reflected in the
Company's Consolidated Statement of Operations for the year ended December 31,
1996. The Company fully utilized its net operating loss carryforwards, at
December 31, 1995, for federal income tax purposes during 1996.

LIQUIDITY AND CAPITAL RESOURCES

         Since its inception, the Company's principal sources of cash have been
cash flow from operations and proceeds from the sale of equity securities. The
Company's investing activities primarily reflect capital expenditures,
acquisitions and net purchases of short-term investments.

         The Company's contracts usually require a portion of the contract
amount to be paid at the time the contract is initiated. Additional payments are
generally received upon completion of negotiated performance milestones
throughout the life of the contract. Cash receipts do not necessarily correspond
to costs incurred or revenue recognized. The Company typically receives a low
volume of large-dollar receipts. Accounts receivable will fluctuate due to the
timing and size of cash receipts. Accounts receivable (net of allowance for
doubtful accounts) was $4.5 million at December 31, 1997 and $8.4 million at
December 31, 1996. Deferred revenue was $852,000 at December 31, 1997 and
$932,000 at December 31, 1996.

         Cash and cash equivalents increased $872,000 during the year ended
December 31, 1997. This was the result of $1.6 million provided by investing
activities, offset by $704,000 used in operating activities. Cash used for
operating activities resulted primarily from the Company's net loss and working
capital needs offset by the decrease in accounts receivable. Investing
activities included net proceeds of $3.0 million from purchases and maturities
of short-term investments offset by $1.4 million used to purchase property and
equipment.


         In January 1998, the Company announced the termination of its
technology alliance agreement with ISSC, a unit of IBM Global Services. The
alliance was formed in June 1996 to develop and market an electronic data
collection and project management system for use in clinical trials. During
1997, the Company invested $1.0 million in the technology alliance. As a result
of the termination of the agreement, the unamortized portion of the Company's
investment was written off in December 1997. The amount written off does not
include expenses incurred by the Company in connection with the technology
alliance throughout 1997. The Company and IBM Global Services disagree on a
number of issues concerning the parties' financial responsibilities in
connection with the termination of the alliance, and have engaged in discussions
concerning those matters. To date, those discussions have not resulted in an
acceptable resolution of these issues. The Company does not believe that it has
any continuing financial obligations to IBM Global Services and, based on
information known to date, does not believe that additional 



                                       18
<PAGE>   21


expenditures associated with the termination of this alliance, if any, will have
a material adverse effect on the Company's results of operations and financial
condition.


         In January 1998, DataTRAK purchased the EDC software known as OpusTWO
from EDS. The Company will be responsible for funding the future development and
testing of this software, which has been renamed DataTRAK EDC(TM). The Company
will continue to invest in the development of the DataTRAK(R) process. As
related to 1997 fourth quarter expense levels, additional expenses of $1.0 to
$1.5 million will be incurred throughout 1998 to build DataTRAK's service
infrastructure.

         In March 1998, the Company announced a reorganization plan including a
reduction of its personnel. In connection with this plan, the Company will
record a charge of approximately $1.4 million in the first quarter of 1998 to
recognize costs associated with employee severance and other special items.

         The Company anticipates that its capital expenditures for 1998 will be
approximately $2.0 million for its DataTRAK and clinical divisions. The
Company's principal cash needs on both a short-term and long-term basis are for
the funding of its operations, capital expenditure requirements, and the
development of its DataTRAK(R) process and service business. The Company
expects to continue expanding its operations through internal growth, joint
ventures and alliances, and after its turn-around has been accomplished,
through strategic acquisitions. The Company expects such activities will be
funded from existing cash and cash equivalents, maturities of short-term
investments, cash flow from operations and borrowings under its line of credit.

         The Company has a line of credit agreement with a bank which provides
for borrowings up to $5.0 million that bears interest at rates not to exceed
prime (no amounts are outstanding at December 31, 1997). The Company's accounts
receivable are pledged as collateral on the line of credit. The line of credit
agreement also requires that the Company maintain investments of $2.0 million
with the bank. Of the $5.0 million line of credit, $2.0 million is considered to
be committed and is subject to renewal at January 31, 2000. The $3.0 million
uncommitted amount is subject to renewal at July 31, 1998.

         As the Year 2000 approaches, an issue has emerged regarding how
existing application software and operating systems can accommodate this date
value. The Company is reviewing its systems to determine if any Year 2000
problems may occur. Management does not anticipate incurring any material
operating expenses or significant computer system investments to be Year 2000
compliant. However, Year 2000 issues incurred by the Company's Affiliated Sites,
Sponsors or other vendors and customers could indirectly affect the Company.

         The Company believes that cash generated from operations, maturities of
short-term investments and amounts available under its line of credit will be
sufficient to fund its working capital and capital expenditure requirements for
the foreseeable future. However, selective acquisitions and joint ventures may
play a role in the Company's growth strategy. To the extent that the Company
were to acquire additional research organizations, it may require additional
capital. There can be no assurance as to the Company's ability to obtain
additional financing.

INFLATION

         To date, the Company believes the effects of inflation have not had a
material adverse effect on its results of operations or financial condition.


                  INFORMATION ABOUT FORWARD LOOKING STATEMENTS

         Certain statements made in this Annual Report on Form 10-K, other SEC
filings or written materials or orally by the Company or its representatives may
constitute forward looking statements. The Company wishes to take advantage of
the safe harbor for forward looking statements provided by the Securities
Litigation Reform Act of 1995 (the "Act"), and is including this information in
its Annual Report on Form 10-K in order to do so. The Company has identified the
following important factors which could cause the Company's actual operational
or financial results to differ materially from any projections, estimates,
forecasts or other forward looking statements made by or on behalf of the
Company. Under no circumstances should the factors listed below be construed as
an exhaustive list of all factors which could 



                                       19
<PAGE>   22


cause actual results to differ materially from those expressed in forward
looking statements made by the Company.

LIMITED OPERATING HISTORY; LACK OF PROFITABLE OPERATIONS

         The Company commenced operations in 1991 and has a limited operating
history upon which investors may evaluate its performance. With the exception of
1996, the Company has recognized losses in each year since its inception. There
can be no assurance that the Company will be profitable during future periods.

FLUCTUATIONS IN QUARTERLY RESULTS

         The Company is subject to significant fluctuations in quarterly results
caused by many factors, including the Company's success in obtaining new
contracts, the size and duration of the clinical trials in which the Company and
members of its Network of Affiliated Sites participate, the timing of Sponsor
decisions to conduct new clinical trials or cancel or delay ongoing trials and
other factors. As a result of the Company's limited operating history, the
Company does not have historical financial data for a significant number of
periods on which to base planned operating expenses. Therefore, the Company's
expense levels are based in part on its expectations as to future revenue and to
a certain extent are fixed. There can be no assurance as to the Company's
revenue in any given period, and it may be unable to adjust expenses in a timely
manner to compensate for any unexpected revenue shortfall. As a result of the
Company's relatively small revenue base, any significant shortfall in revenue
recognized during a particular period could have an immediate adverse effect on
its results of operations and financial condition. There can be no assurance
that the Company will be able to accurately anticipate quarterly results.
Volatility in the Company's quarterly results may adversely affect the market
price of the Company's Common Shares.

RISKS ASSOCIATED WITH UNPROVEN BUSINESS STRATEGIES AND EARLY STAGE OF THE
COMPANY'S DEVELOPMENT

         The Company's efforts to establish a network of Affiliated Sites and
market the Network as a method of streamlining the process of selecting
investigators, conducting clinical trials and to establish a standardized EDC
and QRC process for collection and management of clinical research data
represent a significant departure from the traditional clinical research
practices of Sponsors. The long-term viability of the Company's strategy remains
unproven. There can be no assurance that the Company's strategy will continue to
gain acceptance among Sponsors, research sites or investigators. In that regard,
the Company has undertaken a number of strategic initiatives intended to expand
the scope of its services. These initiatives are identified in this Form 10-K
and in the Company's other SEC filings. All of these initiatives are based upon
assumptions made by the Company concerning trends in the clinical research
market and the health care industry. Any of these assumptions could prove to be
incorrect, which could have a material adverse effect on the Company's business,
results of operations and financial condition. The Company's prospects must be
considered in light of the risks, expenses and difficulties frequently
encountered by companies in their early stages of development, particularly
companies in new and rapidly evolving markets, and there can be no assurance
that the Company will be successful in these efforts.

POTENTIAL DELAY OR LOSS OF CONTRACTS

         Although the Company's contracts with Sponsors provide that it is
entitled to receive revenue earned through the date of termination, Sponsors
generally are free to delay or terminate a clinical trial or the Company's
contract related thereto at any time. The length of a typical clinical trial
contract varies from several months to several years. Sponsors may delay or
terminate clinical trials for several reasons, including unexpected results or
adverse patient reactions to a potential product, inadequate patient enrollment
or investigator recruitment, manufacturing problems resulting in shortages of a
potential product or decisions by the Sponsor to de-emphasize or terminate a
particular trial or drug. A Sponsor's decision to delay or terminate a trial in
which the Company participates could have a material adverse effect on the
Company's business, results of operations and financial condition.



                                       20

DEPENDENCE ON MAJOR CUSTOMERS

         The Company's primary customers are companies in the pharmaceutical
industry. The Company's business is substantially dependent on the research and
development expenditures of companies in this industry. During each of the three
years in the period ended December 31, 1997, sales to companies in the
pharmaceutical industry accounted for more than 69% of the Company's revenue.
During 1995 and 1996, respectively, sales to Merck & Co., Inc. accounted for
approximately 76% and 22% of the Company's revenue. Also during 1996, sales to
Dey Laboratories accounted for 31% of the Company's revenue. Other customers in
the pharmaceutical industry have from time to time accounted for more than 10%
of the Company's annual revenue. The extent to which the Company relies on sales
to one customer varies from period to period, depending upon, among other
things, its ability to generate new business, the timing and size of clinical
trials and other factors. In light of the Company's small revenue base, it is
more dependent on major customers than many of the larger participants in the
clinical research industry. The Company's operations could be materially and
adversely affected by, among other things, any economic downturn in the
pharmaceutical or biotechnology industries, any decrease in their research and
development expenditures or a change in the regulatory environment in which
these companies operate.

RISKS ASSOCIATED WITH ACQUISITIONS AND JOINT VENTURES

         The Company has made several acquisitions and has begun a number of
joint ventures. Management expects to continue to seek and evaluate such
opportunities in the future. There can be no assurance that the Company will be
able to successfully integrate and profitably manage the businesses acquired and
joint ventures entered to date or that it will be able to identify, acquire,
successfully integrate or profitably manage additional acquisitions and joint
ventures without substantial costs, delays or other problems. In addition, there
can be no assurance that such endeavors will be profitable at the time of their
acquisition or that these businesses will achieve or maintain revenue and
profitability that justify the investment therein. Such endeavors involve a
number of special risks, including adverse effects on the Company's reported
operating results, potentially dilutive issuances of equity securities, the
incurrence of debt and contingent liabilities, diversion of management's
attention, dependence on retention, hiring and training of key personnel, risks
associated with unanticipated problems or legal liabilities and amortization of
goodwill and acquired company intangible assets, or the write off of assets with
diminished value, some or all of which could have a material adverse effect on
the Company's business, results of operations and financial condition.

EFFECT OF EXPANSION STRATEGY ON THE COMPANY'S CORE BUSINESS

         The Company's efforts to expand the range of its services expose it to
significant risks. As the Company expands its ability to conduct clinical
research through acquisitions and otherwise, circumstances will arise in which
it will compete for research projects with its Affiliated Sites. There can be no
assurance as to the impact of this competition on the Company's relationship
with its current Affiliated Sites or on its ability to continue to expand the
Affiliated Site Network. The Company's inability to continue to expand its
Network of Affiliated Sites, or the withdrawal of a significant number of
Affiliated Sites or those with expertise in certain therapeutic areas, could
have a material adverse effect on the Company's business, results of operations
and financial condition. In addition, because of the rapid access to clinical
investigators provided by the Company's Affiliated Site Network, CROs have from
time to time engaged the Company to assist them in the site selection process.
During fiscal 1995, 1996 and 1997, services provided to CROs represented
approximately 6%, 7% and 12%, respectively, of the Company's total revenue.
There is no assurance that CROs will continue to do business with the Company.

MANAGEMENT OF GROWTH; NEED FOR IMPROVED SYSTEMS

         The Company believes that the expansion of its business will continue
to place a strain on its operational, human and financial resources. In order to
manage such expansion, the Company must 



                                       21
<PAGE>   24


continue to improve its operating, administrative and information systems and
accurately predict its future personnel and resource needs. In addition,
expansion of foreign operations also may involve the additional risks of
assimilating differences in foreign business practices, hiring and retaining
qualified personnel and overcoming language barriers. Failure by the Company to
meet the demands of and to manage expansion of its business and operations could
have a material adverse effect on the Company's business, results of operations
and financial condition.

LIMITED OBLIGATIONS OF AFFILIATED SITES

         The Company's Network of Affiliated Sites is essential to its business.
The Company enters into affiliation agreements with each Affiliated Site. The
obligations of Affiliated Sites under the affiliation agreements are limited.
Affiliated Sites have full discretion as to whether to participate in clinical
research opportunities presented by the Company, are free to pursue research
opportunities presented to them from sources other than the Company and may
withdraw from the Network at any time.

DEPENDENCE ON KEY PERSONNEL

         As of January 31, 1998, the Company had approximately 150 full-time
employees, of whom eight had executive and managerial responsibilities. The
Company's growth continues to place significant demands on its management
resources. The success of the Company's business is dependent on the services of
its senior management team, which changed substantially in 1997. The Company has
employment agreements with all but one of its executive officers. The loss of
the services of any of its executive officers could have a material adverse
effect on the Company. The Company's performance depends on its ability to
attract and retain qualified personnel. The level of competition among employers
for skilled personnel is high. There can be no assurance that the Company will
be able to continue to attract and retain qualified personnel.

GOVERNMENT REGULATION; POTENTIAL IMPACT OF HEALTH CARE REFORM

         Demand for the Company's services is largely a function of the
regulatory requirements associated with the approval of an NDA by the FDA. These
requirements are more stringent and thus more burdensome than those imposed by
many other developed countries. In recent years, efforts have been made to
streamline the drug approval process and coordinate U.S. standards with those of
other developed countries. Changes in the level of regulation, including a
relaxation in regulatory requirements or the introduction of simplified drug
approval procedures could have a material adverse effect on the demand for the
Company's services. Several competing proposals to reform the system of health
care delivery in the United States have been considered by Congress from time to
time. None of the proposals have been adopted.


         The FDA's guidelines related to the use of computerized systems in
clinical trials are still in the early stages of development. There can be no
assurance that the DataTRAK(R) process can be kept in compliance with these
guidelines as they develop.


         The failure of the Company to comply with applicable regulations could
result in the termination of on-going research or the disqualification of data
for submission to regulatory authorities. Further, the issuance of a notice or
finding by the FDA to either the Company or its clients based upon a material
violation by the Company of either Good Clinical Practices or Good Laboratory
Practices could have a material adverse effect on the Company's business,
results of operations and financial condition.

COMPETITION

         The clinical research industry is highly fragmented and is comprised of
several large, full-service CROs and many small CROs and limited service
providers. The major competitors in the industry include 



                                       22
<PAGE>   25


the research departments of pharmaceutical companies, CROs and SMOs. Many of the
Company's competitors have substantially greater financial and other resources
than the Company, and there can be no assurance of the Company's ability to
continue to compete effectively with these larger competitors. There can be no
assurance that these larger competitors will not develop their own networks of
Affiliated Sites, nor as to the effect of such competing networks on the
Company's operations. The Company may also face competition from other networks
of research sites in the recruitment of potential Affiliated Sites.


         The electronic data capture market, which is still developing, is also
highly fragmented. The major competitors include EDC software vendors, clinical
trial data service companies and in-house development efforts within large
pharmaceutical companies. There can be no assurance that the Company will be
able to capture or establish the market presence necessary to effectively
compete in this emerging sector of the clinical research industry.


POTENTIAL LIABILITY FROM OPERATIONS

         Clinical trials involve the testing of approved and experimental drugs
on human beings. This testing carries with it a significant risk of liability
for personal injury or death to participants resulting from an adverse reaction
to, or improper administration of, the potential product. The Company
participates with Sponsors in the site selection process. The Company also
contracts on behalf of its customers with physicians who render, and itself
renders, professional services including administering the drugs being tested to
participants in these trials. Consequently, the Company may be subject to claims
in the event of personal injury or death of persons participating in clinical
trials and arising from professional malpractice of physicians with whom it has
contracted and its own employees. Although the Company is generally indemnified
by its clients for such liability, in order for such indemnification to be
valid, the Company and its employees and agents must act within the bounds of
specific procedural requirements governing the conduct of the clinical trial.
Since the value of the Company's indemnification depends on the financial
viability of the indemnifying party, there can be no assurance that the Company
will be able to rely on such indemnification in each instance of potential
liability. In addition, the Company has significant involvement in the patient
treatment process at its owned research facilities. Accordingly, the Company's
risk of liability for malpractice is increased. If the Company was forced to
undertake the defense of, or found financially responsible for, claims based
upon the foregoing or related risks, there could be a material adverse effect on
the Company's business, results of operations and financial condition.


ANTI-TAKEOVER PROVISIONS, PREFERRED SHARE PURCHASE RIGHTS

         The Company's Articles of Incorporation and By-Laws contain provisions
that may discourage a third party from acquiring, or attempting to acquire the
Company. These provisions could limit the price that certain investors might be
willing to pay for Common Shares of the Company's stock. In addition Preferred
Shares of the Company's stock can be issued by the Company's Board of Directors,
without shareholder approval, whether under the Company's shareholder rights
plan or for other uses determined by the Board. The issuance of Preferred Shares
may adversely affect the rights of common shareholders, the market price of the
Common Shares and may make it more difficult for a third party to acquire a
majority of the outstanding Common Shares of the Company. At the present time,
the Company does not plan to issue any Preferred Shares.

                         REPORT OF INDEPENDENT AUDITORS




The Board of Directors and Shareholders
Collaborative Clinical Research, Inc.

         We have audited the accompanying consolidated balance sheets of
Collaborative Clinical Research, Inc. and subsidiaries as of December 31, 1996
and 1997, and the related consolidated statements of operations, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. 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 consolidated financial position of
Collaborative Clinical Research, Inc. and subsidiaries at December 31, 1996 and
1997, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1997, in conformity
with generally accepted accounting principles.

1.  ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

Collaborative Clinical Research, Inc. (the "Company") is an SMO managing a
network of affiliated and owned clinical research sites. The Company provides
Sponsors of clinical research (primarily pharmaceutical and biotechnology
companies and, in selected cases, contract research organizations) with an
innovative, timely, cost effective and low risk means of selecting clinical
research sites and managing clinical trials as part of the pharmaceutical
product development process.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.

REVENUE RECOGNITION

Revenue and related direct costs of revenue are recognized as specific contract
terms are fulfilled under the percentage of completion method (the units of
delivery method). Fees for individual contract services are fixed upon execution
of the contract and provide for payment for all work performed. Pass-through
costs that are paid directly by the Company's clients, and for which the Company
does not bear the risk of performance, are excluded from revenue. The
termination of a contract results in no material adjustments to the revenue or
costs previously recognized.

The following sets forth the revenue generated by customers who accounted for
more than 10% of the Company's revenue during each of the periods presented (in
thousands):

*  Less than 10% of revenue.


CONCENTRATION OF CREDIT RISK

The Company is subject to credit risk through accounts receivable and short-term
investments. Credit risk with respect to accounts receivable is minimized
because of the diversification of the Company's customer base and its
geographical dispersion. The Company generally does not require collateral and
the majority of its accounts receivable is unsecured. Short-term investments are
placed with high credit-quality financial institutions or in short-duration with
high credit-quality debt securities. The Company limits the amount of credit
exposure in any one institution or type of investment instrument.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
================================================================================


CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. Investments in cash
equivalents are carried at cost which approximates market value.

PREPAID EXPENSES

Included in prepaid expenses is $108,300 and $126,600 at December 31, 1996 and
1997, respectively, advanced to vendors for services to be provided under
current contracts.

SHORT-TERM INVESTMENTS

Short-term investments are comprised of U.S. Treasury securities and obligations
of U.S. government agencies, obligations of states and U.S. corporate securities
with maturities of one year or less. These securities are stated at amortized
cost, which approximates fair value. The Company has the positive intent and
ability to hold the securities to maturity.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciable assets consist of
medical, office and computer equipment. Depreciation on equipment is computed
using the straight-line method over estimated useful lives of 3 to 7 years.
Leasehold improvements are amortized using the straight-line method over the
lesser of the assets' estimated useful life or the lease term.

DEFERRED REVENUE

Deferred revenue represents cash advances received in excess of revenue earned
on on-going contracts. Payment terms vary with each contract but may include an
initial payment at the time the contract is executed, with future payments
dependent upon the completion of certain contract phases or targeted milestones.
In the event of contract cancellation, the Company is entitled to payment for
all work performed through the point of cancellation.

NET INCOME (LOSS) PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings per Share" ("Statement 128"), which replaced the previously reported
primary and fully diluted earnings per share with basic and diluted earnings per
share. All earnings per share amounts for all periods have been restated to
conform to the Statement 128 requirements.

STOCK BASED COMPENSATION

The Company accounts for stock based compensation in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25").

GOODWILL

The Company has classified as goodwill the cost in excess of fair value of the
net assets acquired in purchase transactions. Goodwill is amortized over a
20-year period using the straight-line method. The carrying value of

              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
================================================================================


goodwill is evaluated if circumstances indicate a possible impairment in value.
If undiscounted cash flows over the remaining amortization period indicate that
goodwill may not be recoverable, the carrying value of goodwill will be reduced
by the estimated shortfall of cash flows on a discounted basis.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
might affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

FINANCIAL INSTRUMENTS

The carrying values of cash and cash equivalents, accounts receivable, accounts
payable and accrued expenses are reasonable estimates of their fair value due to
the short-term of these financial instruments. Investments are reported at
amortized cost which approximates fair value.

ADVERTISING COSTS

Advertising costs are expensed as incurred and are included in selling, general
and administrative expenses. Advertising expenses were $309,000, $173,000 and
$302,000 for 1995, 1996 and 1997, respectively.

RECLASSIFICATION

Certain prior year amounts have been reclassified to conform to the current year
reporting presentation.

2.  SPECIAL ITEMS

Results of operations for 1997 include fourth quarter charges of $2,994,597 or
($0.47) per share for costs associated with exiting certain Company activities.
These charges were for the disposal of certain medical equipment, computer
software and licenses and the closing of a leased facility. In addition the
Company has made a provision for its best estimate of costs associated with the
termination of the technology alliance between IBM and the Company's wholly
owned subsidiary, DataTRAK, Inc.

3.  ACCOUNTS RECEIVABLE

Accounts receivable consist of the following:

11.  STOCK BASED COMPENSATION


The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options. As discussed below, the alternative
fair value accounting provided for under FASB Statement No. 123, "Accounting for
Stock-Based Compensation" requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25 compensation
expense has been recognized for all options granted at less than the fair market
value of the Company's Common Shares on the date of grant (see footnote 10).

Pro forma information regarding net income and earnings per share is required by
Statement 123, which also requires that the information be determined as if the
Company has accounted for its employee stock options granted subsequent to
December 31, 1994 under the fair value method of that Statement. The fair value
for these options was estimated using a Black-Scholes option pricing model with
the following weighted-average assumptions for 1995, 1996 and 1997,
respectively: risk free interest rate of 5.0%, 5.0% and 6.0%, a volatility
factor of the expected market price of the Company's Common Shares of 0.53, 0.53
and 0.66, and a dividend yield of 0.0% for each year and a weighted-average
expected life of the option of seven years. Using the Black-Scholes model, the
weighted-average fair value of options granted during 1995, 1996 and 1997 was
$2.73, $6.66, and $5.18, respectively.


The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated value of the options is
amortized to expense over the options' vesting period. The pro forma results are
not necessarily indicative of what would have occurred had the Company adopted
Statement 123. The Company's pro forma information follows:

12.  RETIREMENT SAVINGS PLAN

The Company sponsors The Collaborative Clinical Research, Inc. Retirement
Savings Plan (the "Plan") as defined by section 401(k) of the Internal Revenue
Code of 1986, as amended. The Plan covers substantially all employees who elect
to participate. Participants may contribute up to 20% of their annual
compensation into a variety of mutual fund options or Common Shares of the
Company's stock. Matching and profit sharing contributions by the Company are
discretionary.


13.  ACQUISITIONS

During the year ended December 31, 1996, the Company completed two acquisitions.
Effective January 31, 1996, the Company acquired GFI, located in Evansville,
Indiana. The purchase price was $6.0 million and consisted of

$2.0 million each of cash, Common Shares (148,148) and notes payable. The notes
payable were paid in full in June 1996. Effective October 25, 1996, WCE, in
Indianapolis, Indiana was acquired by the Company for $3.0 million in cash. The
excess purchase price over the fair value of the net assets acquired was
recorded as goodwill in both acquisitions.

Both acquisitions have been accounted for under the purchase method of
accounting, and the consolidated results of operations include the results of
each business from the date of acquisition. Unaudited pro forma data for the
year ended December 31, 1995 and 1996 as though the Company had completed its
initial public offering and used the net proceeds to repay approximately $3.25
million in indebtedness and purchase GFI and WCE at the beginning of 1995 are
set forth below. The pro forma operating results are not necessarily indicative
of what would have occurred had the transactions taken place on January 1, 1995.

14.  INVESTMENT IN HRI

In June 1995, the Company entered into an equally owned joint venture, Health
Research Innovations L.L.C. ("HRI"), with Pharmaceutical Marketing Services,
Inc. ("PMSI") to collect health care information. Through HRI, the Company and
PMSI marketed their health care data collection and analysis capabilities to the
health care industry. During 1997, the joint venture was terminated. The Company
accounted for its investment in HRI using the equity method.

15.  NET INCOME (LOSS) PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement 128, which
replaced the calculation of primary and fully diluted earnings per share with
basic and diluted earnings per share. Unlike primary earnings per share, basic
earnings per share excludes any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is very similar to the
previously reported net income (loss) per share. In addition, effective February
3, 1998, the Securities and Exchange Commission issued Staff Accounting Bulletin
(SAB) No. 98. SAB 98 revises the views of the staff contained in certain topics
of the staff accounting bulletin series, including SAB 83, "Earnings Per Share
Computations in an Initial Public Offering," to be consistent with the
provisions of Statement 128. All earnings per share amounts for all periods have
been restated to conform to the requirements of Statement 128 and SAB No. 98.

Certain Common Share options were excluded from the computation of diluted
earnings per share since the exercise prices were greater than the average
market price of Common Shares which would have an antidilutive effect on net
income (loss) per share.

                  dollars ($2,000,000.00) outstanding at any one time. The
                  Lender during the loan period, upon the request of the
                  Company, shall also continue Loans of any type or any portion
                  thereof or convert Loans of one type or any portion thereof,
                  into Loans of another type at appropriate intervals.

         (b)      The Lender may in its sole and absolute discretion make one or
                  more Loans to the Company on an Advised Line of Credit, in an
                  aggregate principal amount not to exceed Three Million Dollars
                  ($3,000,000.00) outstanding at any one time. The Lender may in
                  its discretion continue this Loan.

        (c)       The Lender will make one or more Loans to the Company under
                  the Revolving Line Credit from time to time on and after the
                  date of this Agreement through and including the Termination
                  Date, in an aggregate principal amount not to exceed the
                  Committed Amount outstanding at any one time. The Lender shall
                  upon the request of the Company continue Loans of any type or
                  any portion thereof or convert Loans of any type or any
                  portion thereof into Loans of another type at appropriate
                  intervals. The Company may borrow, prepay, and reborrow such
                  Loans; provided, however, that the Company may prepay any
                  Libor Rate Loan only on the last day of the applicable
                  Interest Period for such Loan. The Company may at any time or
                  from time to time, upon not less than ninety (90) Business
                  Days' prior notice made by telegraph, telex, or telephone and
                  confirmed in a writing delivered to the Lender, terminate or
                  reduce permanently the commitment of the Lender to make Loans
                  pursuant to this Section 2.1(a) hereof by the amount of
                  $100,000.00 or any integral multiple thereof; provided that
                  the Company shall immediately pay to the Lender the amount, if
                  any, by which the aggregate principal amount of such Loans
                  outstanding exceeds such reduced commitment of the Lender at
                  that time. If, however, after giving effect to any such
                  payment any Libor Rate Loans would be prepaid prior to the end
                  of their respective Interest Periods, the notice of the
                  termination or permanent reduction in the commitment of the
                  Lender to make Loans pursuant to Section 2.1(a) shall be
                  deemed to be the Company's request that such termination or
                  reduction be effective on the last day of such Interest
                  Periods. Concurrently with such reduction or termination, the
                  company shall pay the unpaid commitment fee that shall have
                  accrued on the portion of such terminated or reduced
                  commitment.

         (d)      Each Loan that is made as or converted into a Prime Rate Loan
                  shall be made or converted on such Business Day in such amount
                  (equal to One Hundred Thousand Dollars ($100,000.00) or an
                  integral multiple thereof) as the Company shall request by
                  written notice given to the Lender no later than 11:00 a.m.
                  (Cleveland, Ohio time) on the date of disbursement of or
                  conversion into the requested Prime Rate Loan, each Loan that
                  is made or continued as or converted into a Libor Rate Loan
                  shall be made, continued, or converted on such Business Day,
                  in such amount (equal to One Hundred Thousand Dollars
                  ($100,000.00) or an integral multiple thereof), and with such
                  an interest Period as the Company shall request by written
                  notice given to the Lender no later than 11:00 a.m.
                  (Cleveland, Ohio time) on the third Business Day prior to the
                  date of disbursement or continuation of or conversion into the
                  requested Libor Rate Loan. Each written notice of any 

                                       4
<PAGE>   5
                  Libor Rate Loan shall be irrevocable and binding on the
                  Company and the Company shall indemnify the Lender against any
                  loss or expense incurred by the Lender as a result of any
                  failure by the Company to consummate such transaction,
                  including, without limitation, any loss (including loss of
                  anticipated profits) or expense incurred by reason of
                  liquidation or re-employment of deposits or other funds
                  acquired by the Lender to fund the Loan. A certificate as to
                  the amount of such loss or expense submitted by the Lender to
                  the Company shall be conclusive and binding for all purposes,
                  absent error. In the event that the Company fails to provide
                  the Lender with the required written notice, the Company shall
                  be deemed to have given a written notice that such Loan shall
                  be converted to a Prime Rate Loan on the last day of the
                  applicable Interest Period. All Loans shall be evidenced by
                  the Note, dated the date hereof. The Note shall be a master
                  note, and the principal amount of all loans outstanding shall
                  be evidenced by the Note or any ledger or other record of the
                  Lender, which shall be presumptive evidence of the principal
                  owing and unpaid on the Note.

         (e)      The Company shall repay to the Lender on the Termination Date,
                  the principal amount of all Loans under the Revolving Line of
                  Credit evidenced by the Note that are outstanding on the
                  Termination Date.

         (f)      The Company shall repay to the Lender on the earlier of July
                  31, 1998 or demand, the amount of all Loans under the Advised
                  Line of Credit.

         SECTION 2.2.  INTEREST RATE.
                       --------------

         (a)      Each Libor Rate Loan shall bear interest at a fixed rate per
                  annum equal to the Libor Rate for such Interest Period plus
                  the Applicable Margin.

         (b)      Each Prime Rate Loan shall bear interest at a floating rate
                  per annum equal to Prime Rate. In the event of any change in
                  the Prime Rate, the rate of interest upon each Prime Rate Loan
                  shall be adjusted to immediately correspond with such change,
                  except such interest rate shall not exceed the highest rate
                  permitted by law.

         SECTION 2.3. INTEREST PAYMENTS. The Company shall pay to the Lender
interest on the unpaid principal balance of each Prime Rate Loan monthly

Rate Loan. The Company shall pay to the Lender interest on the unpaid principal
balance of each Libor Rate loan outstanding on the date such Loan is converted
to a Prime Rate Loan, or the last day of the applicable Interest Period of such
Loan, whichever is earlier. After maturity, whether by acceleration or
otherwise, the principal of the Loans and the unpaid interest and fees thereon
shall bear interest at three percent (3%) in excess of the highest applicable
interest rate provided herein.


         SECTION 2.4. PREPAYMENT. The Company may prepay any Prime Rate Loans in
whole, or in part, in the principal amount of $50,000.00 or any integral
multiple thereof, at any time or times upon not less than one (1) Business Day's
prior notice made by telephone to the Lender. The Company may prepay any Libor
Rate Loan, in whole or in part, in the principal amount of $50,000.00 or any
integral multiple thereof only on the last day of the Interest Period applicable
to such Loan upon not less than one (1) Business Day's prior written notice
given to the Lender.

         SECTION 2.5. USE OF PROCEEDS. The Loans shall be used as working
capital. Any excess proceeds shall be used by the Company for general operating
purposes consistent with the provisions of this Agreement.

         SECTION 2.6.  FEES.  The Company shall pay to the Lender:

         (a)      An origination fee equal to Five Thousand Dollars ($5,000.00)
                  for the Revolving Credit Line of Credit payable on the date of
                  execution of this agreement.

         (b)      A commitment fee computed at the rate of 25 basis points on
                  the unused portion of the Committed Amount. The commitment fee
                  will be paid quarterly in arrears.

         (c)      Prior to maturity (whether acceleration or otherwise), for
                  each payment of principal or interest not paid when due, a
                  late fee equal to five percent (5.0%) of such payment shall be
                  charged.

         (d)      Out of pocket expenses, including Lender's legal fees will be
                  paid by the Company on the date of execution of this
                  Agreement.

         SECTION 2.7 COMPUTATION OF INTEREST AND FEES. Interest on Loans shall
be computed on the basis of a year of 360 days and paid for the actual number of
days elapsed. Interest on unpaid fees, if any, hereunder shall be computed on
the basis of a year of 360 days and paid for the actual number of days elapsed.

         SECTION 2.8  ADDITIONAL COSTS.
                      -----------------

         (a)      If, due to either (i) the introduction of, or any change in,
                  or in the interpretation of, any law or regulation or (ii) the
                  compliance with any guideline or request from any central bank
                  or other governmental authority (whether or not having the
                  force of law), there shall be any increase in the cost to the
                  Lender of making, funding or maintaining Loans, then the
                  Company shall from time to time, upon demand by the Lender pay
                  to the Lender additional amounts sufficient to reimburse the
                  Lender for any such additional costs. A certificate of the
                  Lender submitted to the Company as to the amount of such
                  additional costs, shall be conclusive and binding for all
                  purposes, absent manifest error. Upon notice from the Company
                  to the Lender within five (5) Business Days after the Lender
                  notifies the Company of any such additional costs pursuant to
                  this Section 2.8(a), the Company may either (A) prepay in full
                  all Loans of any types so affected then outstanding, together
                  with interest accrued thereon to the date of such prepayment,
                  or (B) convert all Loans of any types so affected then
                  outstanding into Loans of any other type not so affected upon
                  not less than four (4) Business Days' notice to the Lender. If
                  any such prepayment or conversion of any Libor Rate Loan
                  occurs on any day other than the last day of the applicable
                  Interest Period for such Loan, the Company also shall pay to
                  the Lender such additional amounts sufficient to indemnify the
                  Lender against any loss, cost, or expense incurred by the
                  Lender as a result of such prepayment or conversion,
                  including, without limitation, any loss (including loss of
                  anticipated profits), cost, or expense incurred by reason of
                  the liquidation or reemployment of deposits or other funds
                  acquired by the Lender to fund any such Loan, and a
                  certificate as to the amount of any such loss, cost, or
                  expense submitted by the Lender to the Company shall be
                  conclusive and binding for all purposes, absent manifest
                  error.

         (b)      If either (i) the introduction of, or any change in, or in the
                  interpretation of, any law or regulation or (ii) the
                  compliance with any guideline or request from any central bank
                  or other governmental authority (whether or not having the
                  force of law), affects or would affect the amount of capital
                  required or expected to be maintained by the Lender or any
                  corporation controlling the Lender and the Lender determines
                  that the amount of such capital is increased by or based upon
                  the existence of the Loans (or commitment to make the Loans)
                  and other extensions of credit (or commitments to extend
                  credit) of similar type, then, upon demand by the Lender, the
                  Company shall pay to the Lender from time to time as specified
                  by the Lender additional amounts sufficient to compensate the
                  Lender in the light of such circumstances, to the extent that
                  the Lender reasonably determines such increase in capital to
                  be allocable to the existence of the Lender's Loans (or
                  commitment to make the Loans). A certificate of the Lender
                  submitted to the Company as to such amounts shall be
                  conclusive and binding for all purposes, absent manifest
                  error. Upon notice from the Company to the Lender within five
                  (5) Business Days after the Lender notifies the Company of any
                  such additional costs pursuant to this Section 2.8(b), the
                  Company may either (A) prepay in full all Loans of any types
                  so affected then outstanding, together with interest accrued
                  thereon to the date of such prepayment, or (B) convert all
                  Loans of any types so affected 

                                       6

<PAGE>   7
                  then outstanding into Loans of any other type not so affected
                  upon not less than four (4) Business Days' notice to the
                  Lender. If any such prepayment or conversion of any Libor Rate
                  Loan occurs on any day other than the last day of the
                  applicable Interest Period for such Loan, the Company also
                  shall pay to the Lender such additional amounts sufficient to
                  indemnify the Lender against any loss, cost, or expense
                  incurred by the Lender as a result of such prepayment or
                  conversion, including, without limitation, any loss (including
                  loss of anticipated profits), cost, or expense incurred by
                  reason of the liquidation or reemployment of deposits or other
                  funds acquired by the Lender to fund any such Loan, and a
                  certificate as to the amount of any such loss, cost, or
                  expense submitted by the Lender to the Company shall be
                  conclusive and binding for all purposes, absent manifest
                  error.

         SECTION 2.9. ILLEGALITY. Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law or regulation shall make it unlawful, or any central bank or other
governmental authority shall assert that it is unlawful, for the Lender to
perform its obligations hereunder to make, continue, or convert Libor Rate Loans
hereunder, then, (a) on notice thereof by the Lender to the Company, the
obligation of the Lender to make or continue a Loan of a type so affected or to
convert any type of Loan into a Loan of a type so affected shall terminate and
the Lender shall thereafter be obligated to make Prime Rate Loans whenever any
written notice requests any type of Loans so affected and (b) upon demand
therefor by the Lender to the Company, the Company shall either (i) forthwith
prepay in full all Loans of the type so affected then outstanding, together with
interest accrued thereon or (ii) request that the Lender, upon four (4) Business
Days' notice, convert all Loans of the type so affected then outstanding into
Loans of a type not so affected. If any such prepayment or conversion of any
Libor Rate Loan occurs on any day other than the last day of the applicable
Interest Period for such Loan, the Company also shall pay to the Lender such
additional amounts sufficient to indemnify the Lender against any loss, cost, or
expense incurred by the Lender as a result of such prepayment or conversion,
including, without limitation, any loss (including loss of anticipated profits),
cost, or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by the Lender to fund any such Loan, and a
certificate as to the amount of any such loss, cost, or expense submitted by the
Lender to the Company shall be conclusive and binding for all purposes, absent
manifest error.

the foregoing shall constitute "cash collateral" for purposes of this Agreement.

addition to, not in limitation of, any other right, power, privilege, or remedy,
either in law, in equity, or otherwise, to which the Lender may be entitled. No

remedy will operate as a waiver thereof, nor will any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right hereunder.

HERBERT L. HUGILL (the "Employee").

                                   WITNESSETH:

         WHEREAS, the Employee wishes to become employed by the Company; and

         WHEREAS, the Company desires to employ Employee consistent with the
terms of this Agreement; and

         WHEREAS, the Employee and the Company desire to enter into an agreement
expressly indicating the terms and conditions of their relationship;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained herein, the Company and the Employee agree as follows:

         1. DUTIES. The Company employs Employee in the position of Chief
Operating Officer. Employee shall generally be responsible for overall

by virtue of his position and shall devote his full business time and efforts to
the affairs of the Company. The Employee may, however, serve as an outside
director of any other corporation provided Employee obtains the written consent
of the Company, which shall not be unreasonably withheld.

         2. SALARY. The Company will pay Employee a base salary of One Hundred
Seventy Thousand Dollars ($170,000.00) per year in accordance with the Company's
payroll practices, or in such other periodic method to which both parties agree,
minus appropriate withholdings and deductions. The Company will review
Employee's compensation hereunder on an annual basis, and may adjust the
above-indicated level, in its sole discretion, based on Employee's performance
of his duties hereunder and/or the performance of Collaborative Clinical
Research, Inc., provided, however, that the Company shall not reduce the
Employee's salary to be paid in any succeeding year to an amount less than the
Employee's base salary as established herein. Both parties agree that the above
reference to an "annual base salary" or to other benefits of employment,
including but not limited to bonuses, does not in any way guarantee and/or add
to the express length of employment of Employee, other than as set forth herein.

the Stock Option Agreement. The employee will be entitled to receive additional

additional stock option grants will be based upon the Employee achieving
established targets as outlined in Exhibit A. The strike price for these
additional stock option grants will be the closing price as quoted on the NASDAQ
on the date of grant (1/1/99, 1/1/00, 1/1/01).

         4. BENEFITS. During the course of employment, Employee shall be

conditions of this Agreement.

               7.2 TERMINATION FOR DISABILITY. The Company and the Employee

are unique and critical to the Company and that a disability condition which
causes the Employee to be unable to perform the essential functions of his
position with or without reasonable accommodations for a period in excess of one
hundred twenty (120) calendar days will constitute an undue hardship on the
Company. If the Company determines in good faith upon medical certification and
in consultation with Employee and, if necessary or appropriate, with Employee's
physician(s), that the Employee is disabled and unable to perform the essential
function of his position with or without reasonable accommodations, it may give

workplace, which in the Company's reasonable determination has an adverse effect
on the reputation or business of the Company; or

               7.4 SUSPENSION. In the event Employee engages in conduct
subjecting Employee to potential civil or criminal liability which could have an
adverse effect upon the Company's reputation or business or is related to
Employee's duties and responsibilities, the Company reserves the right to
immediately suspend Employee with pay, pending investigation and/or the outcome
of the matter.

               7.5 TERMINATION BY EMPLOYEE. Employee may terminate his
employment and this Agreement at any time for any or no reason. Employee
