                                PROXY STATEMENT
                            MAILED ON MARCH 17, 1999
                            ------------------------
 
                        SPECIAL MEETING OF SHAREHOLDERS
                          TO BE HELD ON APRIL 14, 1999
 
                                  INTRODUCTION
 
     This Proxy Statement is being furnished to the holders of Common Shares of
Collaborative Clinical Research, Inc. It is being used to solicit proxies on
behalf of the Board of Directors of the Company to be voted at a Special Meeting
of Shareholders to be held at 10:00 a.m. at The National City Bank Auditorium,
Fourth Floor, Atrium Building, 1900 East Ninth Street, on April 14, 1999.
 
     You may vote in favor of, against or abstain from voting on the proposals
and should specify your choice on the enclosed form of proxy. You may revoke a
proxy that you deliver by notifying the Secretary of the Company in writing of
your decision to revoke it. You may also revoke a proxy by delivering a later
dated proxy or by attending the Special Meeting and voting in person. If you
deliver a properly executed proxy and do not revoke it, it will be voted at the
Special Meeting as you direct.
 
     If you do not instruct us in your proxy as to how you want your shares
voted, your shares will be voted "FOR" the approval and adoption of the
proposals. We need the affirmative vote of at least a majority of the Common
Shares outstanding as of the record date in order to approve the agreement
between Collaborative and West and to approve the change of Collaborative's name
to DataTRAK International, Inc. With respect to the approval of the amendment to
the Company's 1996 Outside Directors Stock Option Plan, we need the affirmative
vote of at least a majority of the outstanding Common Shares that are present,
in person or by proxy, and entitled to vote at the Special Meeting.
 
     The Company is paying for this solicitation. Brokers, custodians and
fiduciaries will be requested to forward proxy soliciting materials to the
beneficial owners of shares held in their name, and the Company will reimburse
them for their out-of-pocket expenses in connection therewith. Directors,
officers and management employees of the Company may, without additional
compensation, solicit proxies by telephone, mail and personal interview.
 
     Only holders of record of Common Shares of the Company at the close of
business on March 3, 1999, are entitled to vote at the Special Meeting or
adjournments thereof. Each holder of record on the record date is entitled to
one vote for each Common Share that it holds. On March 3, 1999, there were
6,430,872 Common Shares of the Company issued and outstanding. A majority of the
outstanding shares will constitute a quorum at the Special Meeting. In voting on
the proposals, votes may be cast in favor, against or abstained. Under
applicable Ohio law, if a broker, custodian or fiduciary returns a proxy and has
not voted on a certain proposal, such broker non-votes are counted as present
for purposes of determining the presence of a quorum.
 
     With respect to the proposal to approve the agreement between Collaborative
and West and the proposal to change the Company's name, abstentions and broker
non-votes will have the same effect as a vote against such proposals. With
respect to the proposal to amend the Company's 1996 Outside Directors Stock
Option Plan, abstentions will have the same effect as a vote against such
proposal. However, because shares represented as broker non-votes are not
regarded as being present and entitled to vote on this proposal, broker
non-votes will have no effect on the outcome of such proposal.

     You may also obtain copies of this information by mail from the Public
Reference Section of the SEC, 450 Fifth Street, N.W., Room 1024, Washington

SEC's Public Reference Room in Washington, D.C. may be obtained by calling the
SEC at 1-800-SEC-0330.
 
     The SEC also maintains a world wide web site that contains reports, proxy
statements and other information about registrants, such as us, that file
electronically with the SEC. The address of that web site is http://www.sec.gov.
 
     No one is authorized to give any information or make any representation
about the agreement between the Company and West, the change of the Company's
name, the amendment to the Company's 1996 Outside Directors Stock Option Plan or
about Collaborative Clinical Research, Inc. that is different from or in
addition to the information contained in this Proxy Statement or any of the
attached appendices. Therefore, if anyone does give you information of this
sort, you should not rely on it. The information contained in this document
speaks only as of the date of this document unless the information specifically
indicates that another date applies.
 
                  INFORMATION ABOUT FORWARD-LOOKING STATEMENTS
 
     Certain sections in this Proxy Statement, including "Summary,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," and "Description of the Business," contain certain forward-looking
statements that are based on management's current beliefs, estimates, and
assumptions concerning the operations, future results, and prospects of
Collaborative and the clinical pharmaceutical research industry in general. All
statements that address operating performance, events or developments that
management anticipates will occur in the future, including statements related to
future sales, profits, expenses, income and earnings per share, or statements
expressing general optimism about future results, are forward-looking
statements. In addition, words such as "expects," "anticipates," "intends,"
"plans," "believes," "estimates," variations of such words, and similar
expressions are intended to identify forward-looking statements.
 
     The statements described in the preceding paragraph constitute
"forward-looking statements" within the meaning of Section 21E of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). Because these statements
are based on a number of beliefs, estimates, and assumptions that could cause
actual results to materially differ from those in the forward-looking
statements, there is no assurance that forward-looking statements will prove to
be accurate.
 
     Any number of factors could affect future operations and results, including
the following: the ability of the Company to absorb corporate overhead and other

                                    SUMMARY
 
     The following is a brief summary of certain information contained elsewhere
in this Proxy Statement. This summary is not intended to be complete and is
qualified in all respects by reference to the detailed information appearing
elsewhere in this Proxy Statement and the appendices hereto and the information
incorporated herein by reference.
 
THE SPECIAL MEETING
 
     The Special Meeting will be held at 10:00 a.m., local time, on Wednesday,
April 14, 1999, at The National City Bank Auditorium, Fourth Floor, Atrium
Building, 1900 East Ninth Street, Cleveland, Ohio to consider and vote upon the
following matters:
 
- - - A proposal to approve and adopt the agreement by which we will sell all of our
  assets related to the Company's clinical business to West. The clinical
  business consists principally of our Affiliated Site Network and the clinical
  research and prescription drug to over the counter switch operations conducted
  by our GFI Pharmaceutical Services and WCE Clinical Evaluations subsidiaries;
 
- - - A proposal to approve and adopt a Certificate of Amendment to the Company's
  Certificate of Incorporation changing the name of the Company from
  Collaborative Clinical Research, Inc. to DataTRAK International, Inc.; and
 
- - - A proposal to approve and adopt an amendment to the Company's Amended and
  Restated 1996 Outside Directors Stock Option Plan.
 
     Shareholders of record on March 3, 1999 are entitled to receive notice of
and to vote at the Special Meeting. See "The Meeting -- Time, Date and Place."
 
THE SALE OF THE CLINICAL BUSINESS
 
     West will purchase all of the assets that constitute the entire business of
the clinical business. After the sale, the Company will remain a public company
and will continue to operate its DataTRAK subsidiary. DataTRAK, Inc. has
developed electronic data capture systems for use in clinical research. See
"Proposal to Approve the Sale of the Clinical Business."
 
CONSIDERATION TO BE RECEIVED BY COLLABORATIVE; USE OF PROCEEDS
 
     If the proposed sale is consummated on the terms contemplated by the
agreement, the Company will receive an aggregate consideration of $15.0 million
in cash, subject to positive or negative adjustments to account for net working
capital as of the date of closing and the collection of net accounts receivable.
The Company currently expects to generate an estimated $13.9 million in cash
proceeds from the proposed sale after deduction for such purchase price
adjustments and additional transaction costs. See "Proposal to Approve the Sale
of the Clinical Business -- Positive and Negative Aspects of the Proposed Sale."
The Board has not yet determined how the proceeds of the proposed sale will be
used. The Board's objective is to determine the best method of permitting
shareholders to realize the value of the DataTRAK technology. To this end, the
Board is considering several alternatives that are available to it. The Board is
considering using some of the proceeds to provide working capital to finance
DataTRAK, Inc.'s development and expansion (either independently or in
conjunction with one or more strategic partners). The Board expects to
distribute some portion of the retained cash to the Company's shareholders or
offer to repurchase some of its outstanding Common Shares. The Board is also
considering a possible sale or merger of the Company. However, the Company is
not currently engaged in any discussions or negotiations concerning a sale or
merger of the Company. See "Use of Proceeds; Plans for Future Operations after
the Proposed Sale."
 
INTERESTS OF CERTAIN PERSONS IN THE PROPOSED SALE
 
     The Company's stock option plans provide that all outstanding options will
become fully exercisable upon a change in control. On July 23, 1998, the Board
approved an amendment to the Company's Amended and Restated 1996 Outside
Directors Stock Option Plan under which, among other things, each non-employee
Director received an option to purchase 10,000 Common Shares, subject to
shareholder approval of the amendment. Because the sale of the clinical business
qualifies as a change in control, if the amendment is approved and the proposed
sale is consummated, the Company's Directors and executive officers will own, or
have the right to purchase, an aggregate 24% of the outstand-
 
                                        3
<PAGE>   10
 
ing Common Shares of the Company. In addition, upon the consummation of the
proposed sale Mr. Hugill will be paid a cash bonus of $20,000. As a condition to
the proposed sale, Dr. Green will enter into a two-year non-competition
agreement with West. See "Proposal to Approve the Sale of the Clinical
Business -- Interests of Certain Persons in the Proposed Sale."
 
REQUIRED VOTE AND RECORD DATE
 
     Ohio law requires the affirmative vote of the holders of a majority of our
outstanding Common Shares held as of March 3, 1999 for the approval of the
transaction and the proposed change of the Company's name. Approval of the
proposed amendment to the Company's Amended and Restated 1996 Outside Directors
Stock Option Plan requires the affirmative vote of the holders of a majority of
our outstanding Common Shares present, in person or by proxy, and entitled to
vote at the Special Meeting. The Directors and executive officers of the
Company, who beneficially own, in the aggregate, approximately 21% of the
outstanding Common Shares, have agreed to vote their shares in favor of the
transaction. See "The Meeting -- Vote Required and Record Date."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The Board of Directors of the Company unanimously recommends that the
shareholders approve the agreement, the proposed change of the Company's name
and the amendment to the Company's Amended and Restated 1996 Outside Directors
Stock Option Plan.
 
OPINION OF FINANCIAL ADVISOR
 
     McDonald Investments Inc. has delivered its written opinion to the Board of
Directors of Collaborative that, as of the date of its opinion, the purchase
price for the clinical business was fair, from a financial point of view, to
Collaborative. The opinion of McDonald Investments Inc. does not constitute a
recommendation as to how you should vote with respect to the transactions
contemplated by the agreement. See "Proposal to Approve the Sale of the Clinical
Business -- Reasons for the Proposed Sale; Opinion of Financial Advisor."
 
CONDITIONS TO THE CLOSING
 
     The closing of the proposed sale is conditioned upon the receipt of the
requisite affirmative vote of the Company's shareholders to approve and adopt
the agreement. In addition, the closing of the proposed sale is subject to the
satisfaction of certain customary conditions including, among other things, the
absence of any material adverse change in the operations, properties, assets,
liabilities or financial condition of the Company's clinical business. See
"Proposal to Approve the Sale of the Clinical Business -- Description of the
Agreement and the Proposed Sale; Conditions to the Proposed Sale."
 
THE CLOSING
 
     If Collaborative's shareholders approve the proposal to adopt the
agreement, the closing of the transaction will take place on or about April 16,
1999, or at such other time as Collaborative and West may agree. See "Proposal
to Approve the Sale of the Clinical Business -- Description of the Agreement and
the Proposed Sale; The Closing."
 
ACCOUNTING TREATMENT OF THE PROPOSED SALE
 
     The transaction will be accounted for as a sale of assets. Any adjustment
for the collection of net accounts receivable will be accounted for as a change
in accounting estimate and will be recognized as an adjustment to the Company's
results of operations in the time period that such amount, if any, is
determined.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE PROPOSED SALE
 
     The Company currently expects to report a gain of approximately $11.0 to
$12.0 million from the proposed sale, subject to certain post-closing
adjustments. The Company does not anticipate federal income tax liability as a
result of the reported gain due to the Company's large net operating loss
carryforwards.
 
APPRAISAL RIGHTS
 
     Under Ohio law, Collaborative shareholders that do not vote for the
agreement will have appraisal rights in connection with the approval and
adoption of the agreement and the consummation of the transaction contemplated
thereby. See "Shareholders' Appraisal Rights."

                            PRO FORMA FINANCIAL DATA
 
     The following unaudited Pro Forma Consolidated Balance Sheet as of December
31, 1998 and Consolidated Statements of Operations for the year ended December
31, 1998 are based on the historical financial statements of the Company. The
Pro Forma Consolidated Balance Sheet is adjusted to reflect the proposed sale
(the "Proposed Sale") of the assets and liabilities of the Company's Affiliated
Site Network, and the clinical research operations conducted by GFI
Pharmaceutical Services, Inc. ("GFI") and Collaborative Holdings, Inc. ("WCE")
(the businesses of the Affiliated Site Network, GFI and WCE are hereinafter
collectively referred to as the "Clinical Business") to The West Company,
Incorporated ("West") for $15.0 million in cash, less applicable transaction
costs, adjustments for working capital and the collection of net accounts
receivable contemplated by the asset purchase agreement (the "Agreement") among
the Company, GFI, WCE, DataTRAK, Inc. ("DataTRAK") and West had this transaction
occurred on December 31, 1998. The Proposed Sale is a sale of a business.
Pursuant to the Agreement, all of the assets that constitute the entire business
of the Clinical Business will be sold to West. The Pro Forma Consolidated
Statements of Operations are adjusted to reflect the sale of the Clinical
Business to West and the June and September 1998 closure of other Clinical
Business locations had these transactions occurred as of the beginning of 1998.
The pro forma operating results are not necessarily indicative of the operating
results that would have been achieved had the disposition actually occurred at
the beginning of 1998, nor do they purport to indicate the results of future
operations.
 
     The Pro Forma Consolidated Financial Data is based on the assumptions set
forth in the notes to such data and should be read in conjunction with the
Company's Consolidated Financial Statements and related Notes thereto and other
financial information included elsewhere in this Proxy Statement.

    transaction costs estimated to be $1.2 million and a positive working
    capital adjustment of $13,000 at December 31, 1998. At December 31, 1998 the
    Clinical Business had current assets of $2,803,000 and current liabilities
    of $2,790,000 resulting in a positive working capital of $13,000. The
    adjustment for the collection of net accounts receivable is not included in
    the Pro Forma Consolidated Balance Sheet as such amount will not be
    determined until 180 days after the Proposed Sale, as contemplated by the
    Agreement. The actual working capital adjustment to be made to the purchase
    price will be based upon a final calculation of the net working capital, as
    defined by the Agreement, of the Clinical Business as of the date on which
    the Proposed Sale is consummated and will therefore not be known until after
    such time, as defined by the Agreement.

PROXIES; VOTING AND REVOCATION
 
     When a proxy is properly executed and returned, the common shares, without
par value (the "Common Shares"), of the Company that it represents will be voted
in accordance with the directions indicated on the proxy. If no directions are
indicated on a proxy with respect to the proposals to approve the Agreement, to
change the Company's name or to amend the Company's Amended and Restated 1996
Outside Directors Stock Option Plan, as amended, the shares represented by such
proxy will be counted as votes in favor of such proposal.
 
     COLLABORATIVE SHAREHOLDERS ARE REQUESTED TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO COLLABORATIVE IN THE ENCLOSED
POSTAGE-PAID ENVELOPE, EVEN IF THEY ARE PLANNING TO ATTEND THE SPECIAL MEETING.
 
     A shareholder who has given a proxy may revoke it any time prior to its
exercise at the Special Meeting by (i) giving written notice of revocation to
the Company's Secretary, (ii) properly submitting to the Company a duly executed
proxy bearing a later date or (iii) voting in person at the Special Meeting. All
written notices of revocation and other communications with respect to

Collaborative Clinical Research, Inc., 20600 Chagrin Boulevard, Cleveland, Ohio
44122, Attention: Secretary.
 
VOTE REQUIRED AND RECORD DATE
 
     Under the Ohio General Corporation Law (the "OGCL"), the affirmative vote
of the holders of a majority of the Common Shares outstanding is required to
approve the Agreement and the proposal to change the Company's name. The
affirmative vote of the holders of a majority of the outstanding Common Shares
present, in person or by proxy, at the Special Meeting is required to approve
the proposed amendment to the Company's Amended and Restated 1996 Outside
Directors Stock Option Plan, as amended.
 
     If a shareholder returns his or her proxy card but abstains from voting,
his or her vote will be counted as shares that are present for purposes of
determining whether a quorum is present at the Special Meeting. If a shareholder
abstains and a nominee, such as a broker, custodian or other fiduciary, holds
his or her shares, his or her shares will be counted as present for the purpose
of determining the presence of a quorum at the Special Meeting if the nominee
has the discretion to vote on behalf of the shareholder.
 
     Abstentions and broker non-votes with respect to the proposal to approve
the Agreement and the proposal to change the Company's name have the same effect
as votes against such proposals. With respect to the proposal to amend the
Company's Amended and Restated 1996 Outside Directors Stock Option Plan, as
amended, abstentions will have the same effect as a vote against such proposal.
However, because shares
 
                                        9
<PAGE>   16
 
represented as broker non-votes are not regarded as being present and entitled
to vote on this proposal, broker non-votes will have no effect on the outcome of
this proposal.
 
     Only holders of record of Collaborative Common Shares at the close of
business on March 3, 1999 (the "Record Date") are entitled to receive notice of,
and to vote at, the Special Meeting. As of the Record Date, Collaborative's

Common Shares entitled to vote at the Special Meeting. Each Director and
executive officer of the Company has agreed to vote his Common Shares in favor
of the proposal to approve the Agreement.
 
OTHER MATTERS
 
     Collaborative management does not currently expect any other business to be
brought before the Special Meeting. If any matters come before the Special
Meeting that are not directly referred to in this Proxy Statement, including
matters incident to the conduct of the Special Meeting, the proxy holders will
vote the shares represented by the proxies in accordance with the
recommendations of the Company's management.

             PROPOSAL TO APPROVE THE SALE OF THE CLINICAL BUSINESS
 
     The terms and conditions of the Proposed Sale are contained in the
Agreement, a copy of which is attached to this Proxy Statement as Appendix A and
is incorporated herein by reference. The description in this Proxy Statement of
the terms and conditions of the Proposed Sale is qualified in its entirety by,
and made subject to, the more complete information set forth in the Agreement.
SHAREHOLDERS OF THE COMPANY ARE URGED TO CAREFULLY READ THE AGREEMENT IN ITS
ENTIRETY.
 
DESCRIPTION OF THE BUSINESS
 
     The Clinical Business. The Company's Clinical Business is a multi-specialty
site management organization ("SMO") that provides clinical research services to
three segments of the pharmaceutical and biotechnology industries. Through WCE,
it provides clinical research services relating to the reclassification of
prescription drugs into drugs available for over the counter ("OTC") purchase
and other OTC clinical research services. The Clinical Business also provides
Phase I clinical research services from its 80-bed clinic at GFI. Finally,
through its Affiliated Site Network, which is comprised of six
therapeutic-focused sub-networks drawn from over 450 clinical research sites,
the Clinical Business provides Phase II, III and IV clinical research services.
Although not owned by the Company, each research site in the Affiliated Site
Network is affiliated with the Clinical Business through a written agreement
that describes a cooperative relationship between the Company and the site. The
Clinical Business provides research sites with sales and marketing, project
management, budgeting and contract negotiation services. Subject to customary
provisions contained in the Agreement, upon the consummation of the Proposed
Sale West will retain all of the Company's employees directly involved in the
Clinical Business with the exception of three employees of the Company, two of
which have executive and managerial responsibilities. The Clinical Business has
historically accounted for all of the Company's revenues (approximately $13.2
million for the fiscal year ended December 31, 1998).
 
     The DataTRAK Business. Based on its previous experience in clinical trials,
the Company believed that development of an effective electronic data capture
("EDC") technology presented significant long-term opportunities for revenue and
earnings growth. Data from clinical research trials is generally collected and
verified through a series of on-site visits by clinical trial monitors, who
physically review and verify the various forms completed by each research site
participating in the trial. The Company believed that an effective EDC system
could reduce the costs of the monitoring process and substantially improve the
accuracy of data generated during the trial. In May 1996, Collaborative formed
DataTRAK, a wholly owned subsidiary of the Company that, during 1997,
participated in a joint venture with IBM Global Services for the purpose of
developing and marketing a data collection and management system for use in
clinical trials. At the end of 1997, DataTRAK and IBM Global Services ("IBM")
terminated their joint venture. Before the termination of its joint venture with
IBM, the Company engaged the services of a consultant to assess the
functionality of the system that DataTRAK had developed with IBM and integrate
that system into the Company's Clinical Business services. This consultant was a
former employee with PadCom Clinical Research GmbH ("PadCom") and had an
in-depth knowledge of clinical EDC software and, in particular, the software
then-owned by PadCom. When the joint venture was terminated, this consultant
advised the Company as to the functionality of PadCom's software relative to
other EDC systems that could be purchased by the Company. After reviewing
various software engines and with the advice of its outside consultant as to
technical matters, the Company determined that purchasing the PadCom software
engine would provide a cost-effective method for the Company to enter the EDC
market because PadCom not only had a fully developed software engine and an
existing software development staff, but also had experience in using its EDC
software in clinical trials. In January 1998, DataTRAK purchased the software
now known as DataTRAK EDC(TM) from PadCom for a purchase price of $610,000. The
DataTRAK EDC(TM) software provides clinical research data faster and more
efficiently than the traditional models of clinical data collection currently
employed. DataTRAK provides electronic information-processing capabilities
designed for the clinical research environment through its EDC technology and
Quality Review Center ("QRC") process. The DataTRAK combination of hardware,
software and services expedites the data collection and reporting process during
the conduct of a clinical trial.
 
                                       11
<PAGE>   18
 
     If the Agreement is approved by the Company's shareholders and the Proposed
Sale is consummated, the Company will pursue the development of the business of
DataTRAK and will no longer engage in the operation of the Clinical Business. As
of December 31, 1998, 14 full-time employees were directly involved in the
commercialization of and product development efforts for DataTRAK EDC(TM).
 
USE OF PROCEEDS; PLANS FOR FUTURE OPERATIONS AFTER THE PROPOSED SALE
 
     The Company expects to generate an estimated $13.9 million in cash proceeds
from the Proposed Sale. Based upon the Clinical Business's net working capital
at December 31, 1998, it is currently estimated that the $15.0 million purchase
price to be paid to the Company will be increased by a $13,000 working capital
adjustment and offset by applicable transaction costs of $1.2 million. The
actual proceeds received by the Company in the Proposed Sale will depend on the
Clinical Business's net working capital as of the closing date, and on the
collection of accounts receivable during the 180 days following the closing
date. The use of these proceeds has not been determined. The Board is
considering the possibility of a strategic alliance, a sale of DataTRAK or a
merger with another entity. After the consummation of the Proposed Sale, the
Company expects to retain about $40.0 million in cash. Currently, the Board
expects to distribute some portion of the retained cash to the Company's
shareholders or offer to repurchase some of its outstanding Common Shares.
However, the Board's primary objective is to determine the best method of
permitting shareholders to realize the value of the DataTRAK technology. To this
end, the Board is considering numerous alternatives that are available to it.
Among them, the Board is considering using some of the proceeds to provide
working capital to finance DataTRAK's commercialization and continued product
development (either independently or in conjunction with one or more strategic
partners).
 
     Based on its previous experience in clinical trials, the Company believed
that development of an effective EDC technology presented significant long-term
opportunities for revenue and earnings growth. The Company purchased DataTRAK
EDC(TM) in January 1998 as a fully operational and marketable software
application designed to manage data collected in clinical pharmaceutical trials.
The Company currently markets the DataTRAK EDC(TM) software and the software is
currently being used in ongoing clinical trials. Additionally, since its
purchase of the software, the Company has devoted resources to upgrade, modify
and improve the software application, to expand its available uses within the
field of clinical pharmaceutical research and to research and develop the
available markets for the commercialization of the software. The Board of
Directors has worked with management of the Company and various outside
consultants to determine the market viability and technological strengths of
DataTRAK EDC(TM). The Company estimates a required expenditure of $1.5 to $2.0
million within a two-year time frame on continued commercialization and product
development in order to more successfully compete within the currently emerging
market for EDC software applications.
 
     While the Company has received expressions of interest from various parties
in establishing a partnership to develop and implement the DataTRAK technology,
it is not engaged in any discussions or negotiations concerning a sale or merger
of the Company.
 
THE WEST COMPANY, INCORPORATED
 
     The West Company, Incorporated is a publicly held company that supplies
products and services for packaging and delivery of healthcare and consumer
products. Over 85% of West's revenue is generated by the healthcare markets,
consisting primarily of large, multinational pharmaceutical and medical device
companies. West also provides contract packaging and contract manufacturing
services for the pharmaceutical and consumer products markets in the United
States and Puerto Rico. West's principal executive offices are located at 101
Gordon Drive, P.O. Box 645, Lionville, Pennsylvania 19341-0645, telephone number
610-594-2900.
 
BACKGROUND OF THE PROPOSED SALE
 
     The Company was organized in 1991. Since that time, the Clinical Business
has provided substantially all of the Company's revenue. Considerable resources
have been devoted to expanding the Clinical Business, including efforts to
increase the volume of clinical trials in which the Company's Affiliated Sites
participate,
 
                                       12
<PAGE>   19
 
efforts to expand the range of clinical research services that the Company
provides and acquisitions of businesses providing complementary services.
Despite the Company's efforts, the Clinical Business has been unable to achieve
sustained earnings or revenue growth. For the year ended December 31, 1996, the
Company had net income of $1.6 million. For the years ended December 31, 1997
and 1998, the Company had a net losses of $7.4 million and $14.1 million,
respectively.
 
     In 1997, Collaborative's Board of Directors began to consider alternatives
for enhancing shareholder value. The alternatives considered by the Board
included the possibility of (1) the sale of the Clinical Business or certain of
the assets of the Clinical Business, (2) the sale of DataTRAK, (3) the sale of
the Company or (4) a strategic alliance with another company within the same or
a related market.
 
     Between July 1997 and June 1998, Collaborative contacted 17 companies that
it believed might be interested in pursuing one of the strategic alternatives
being considered by the Board. None of those companies expressed an interest in
purchasing DataTRAK, acquiring the Company or entering into a strategic alliance
with Collaborative on terms that the Board considered favorable to the Company.
Three of the 17 companies contacted expressed preliminary interest in a possible
transaction involving all or part of the Clinical Business.
 
     In July 1998, a representative of West expressed interest in acquiring the
Clinical Business. In August 1998, the Company retained M.W. Pitt Associates,
LLC ("M.W. Pitt") to assist it in further assessing the interest of West and the
parties previously contacted, and also to investigate the interest in acquiring
all or part of the Company among parties that had not previously been contacted.
The Company has agreed to pay M.W. Pitt $5,000 in monthly retainer fees for its
services. Upon the consummation of the Proposed Sale, the Company will pay
$350,000 to M.W. Pitt, to be offset by any previously paid retainer fees.
Between August and November 1998, Collaborative contacted 17 companies,
consisting of six companies that had been contacted in the period from July 1997
to June 1998, ten other companies that had not been previously contacted and
West. Of this group of 17 companies, extensive discussions were held with
twelve. Six of the twelve companies expressed preliminary interest in purchasing
all or part of the Clinical Business. Face-to-face meetings were held with three
of the six, and two of such companies made offers to purchase all or part of the
Clinical Business. The offers presented to the Company did not generally differ
from one another with the exception of variations among the specific assets to
be sold and the amounts offered as consideration. Consequently, the aggregate
purchase price for assets to be sold was the primary determining factor
considered by the Board when comparing the three offers. The offer made by West
was the only offer made for all of the assets of the Clinical Business, and the
purchase price offered by West was the highest price offered to Collaborative.
 
     On October 23, 1998, West met with representatives of the Company and M.W.
Pitt to discuss its proposal to purchase the Clinical Business. Based on these
discussions and the Company's and M.W. Pitt's judgment concerning other
expressions of interest and the limited possibility that a higher offer might be
presented by another company in the future, Collaborative and West prepared a
non-binding term sheet describing the purchase of the Clinical Business by West
for an aggregate $15.0 million in cash, subject to certain post-closing
adjustments. On November 24, 1998, the Company retained the services of McDonald
Investments Inc. ("McDonald") to opine as to the fairness, from a financial
point of view, to the Company of the consideration proposed to be paid by West
for the purchase of the Clinical Business.
 
     Between November 3, 1998 and December 16, 1998, representatives of West
conducted further due diligence review of Collaborative's records and
facilities, including visits to the Company's GFI and WCE facilities and the
administrative office for the Affiliated Site Network. On December 11, 1998,
West's representatives delivered a draft of the Agreement to Collaborative and
its representatives for review and comment. Between December 11, 1998 and
December 21, 1998, Collaborative and West and each of their respective
representatives negotiated the specific terms, conditions, covenants and
representations contained in the Agreement and in the additional agreements
provided for by the terms of the Agreement.
 
     At a special meeting of the Board of Directors of the Company on December
21, 1998, the Board met to review the Agreement with the advice and assistance
of the Company's financial and legal advisors. All Directors of the Company were
present at this meeting. The Company's legal advisors advised the members of
 
                                       13
<PAGE>   20
 
the Board of their legal responsibilities to the Company. The members of the
Board were aware of their respective personal interests, and the interests of
management, with respect to the transaction. See "-- Interests of Certain
Persons in the Proposed Sale." In considering these potential conflicts of
interest, the Board took into account the fact that the vesting of outstanding
stock options awarded to the Company's executive officers resulted from the
change in control vesting provisions of the option plan that had been in effect
since the adoption of the plan in 1996. In the case of options awarded to the
Company's outside Directors, subject to shareholder approval, the Board was
aware that shareholders would have an opportunity to vote on the proposed
amendment to the Amended and Restated Outside Directors Stock Option Plan under
which these options were awarded, and that the Agreement was not contingent on
shareholder approval of this amendment. The Board did not consider awarding a
bonus to Mr. Hugill until after the Agreement was authorized. Subsequently, the
Compensation Committee determined to authorize a $20,000 bonus to Mr. Hugill in
recognition of his efforts in the sale process. The Company's legal advisors and
M.W. Pitt summarized the material terms and conditions of the Agreement.
McDonald's representatives reviewed the sale process, West's proposal and its
evaluation of West's proposal. During this meeting, McDonald rendered to the
Board its opinion to the effect that, as of such date, the proposed
consideration to be paid by West for the Clinical Business pursuant to the
Agreement was fair, from a financial point of view, to the Company. Following
extensive discussion and review of the transaction, the Board unanimously
approved the Agreement with West.
 
     Collaborative and West executed the Agreement on December 21, 1998.
Simultaneously, Collaborative's Directors and executive officers executed the
related voting agreements described in greater detail below. Following the
execution of the Agreement on December 21, 1998, Collaborative and West each
issued press releases announcing the execution of the Agreement.
 
REASONS FOR THE PROPOSED SALE
 
     At a meeting of the Board of Directors of Collaborative held on December
21, 1998, Collaborative's Directors determined that the Agreement and the
Proposed Sale were advisable and fair to, and in the best interests of, the
Collaborative shareholders. Accordingly, Collaborative's Board of Directors
unanimously approved and adopted the Agreement and unanimously recommended that
the Collaborative shareholders approve the Proposed Sale.
 
     In reaching its decision to approve the Agreement and to recommend approval
and adoption of the Proposed Sale by the Company's shareholders, the Board
consulted with Collaborative's management and its financial and legal advisors
and considered a number of factors, including, without limitation, the
following:
 
      (1) The results of the Board's and management's discussions with numerous
          organizations regarding their interest in a strategic alliance or
          other transaction involving the Company;
 
      (2) The Directors' familiarity with the Clinical Business, its operations,
          financial condition and results of operations on a historical and
          prospective basis;
 
      (3) The assessment of opportunities for long-term revenue and earnings
          growth in the Clinical Business;
 
      (4) The current developmental stage of the DataTRAK technology and the
          DataTRAK business operations and the fact that the sale of the
          Clinical Business would involve the disposition of the source of
          substantially all of the Company's historic revenues;
 
      (5) The potential impact of the transaction on the liquidity of the market
          for the Company's Common Shares, including the possibility that the
          transaction might result in a delisting of the shares from the
          Nasdaq's National Market System and may therefore impair the liquidity
          in the trading market for the Common Shares;
 
      (6) The fact that the Company and the Board of Directors had not yet
          definitively determined the use of proceeds from the Proposed Sale or
          the best method to realize the value of the DataTRAK technology;
 
                                       14
<PAGE>   21
 
      (7) The financial presentation of McDonald that the consideration to be
          received by the Company for the assets of the Clinical Business is
          fair, from a financial point of view, to the Company, supported by its
          written opinion (a copy of which is attached hereto as Appendix B);
 
      (8) The terms and conditions of the Agreement, including the significant
          cash to be delivered by West, the cash and other assets retained by
          the Company, the indemnity obligations of the Company to West and the
          terms of the non-competition agreements between West and the Company,
          DataTRAK and Dr. Jeffrey A. Green, President and Chief Executive
          Officer of the Company;
 
      (9) Other provisions of the Agreement, including the protection of
          severance and other benefits afforded to Collaborative's employees;
 
     (10) The stated willingness of Collaborative's Directors and executive
          officers, owning an aggregate 18% of the outstanding Common Shares, to
          enter into voting agreements obligating them to vote their respective
          shares in favor of the Agreement;
 
     (11) The financial wherewithal of West and the fact that, subject to
          standard conditions, the Agreement provides Collaborative with a
          reasonable degree of certainty that the Proposed Sale would ultimately
          be consummated;
 
     (12) The uncertainty, if West's offer were rejected, of negotiating an
          alternative transaction on as favorable a basis with another party
          within a reasonable time frame; and
 
     (13) The fact that, under certain conditions and upon the payment of a
          termination fee, Collaborative has the right to terminate the
          Agreement to accept an offer more favorable to the Company's
          shareholders.
 
     Each of the foregoing factors was considered by the Board during the course
of its deliberations prior to entering into the Agreement in light of its
knowledge of the Clinical Business and each Director's business judgment. In its
deliberations, the Board did not quantify or otherwise attempt to assign
relative weights to the specific factors considered in determining to approve
(and to recommend that the shareholders approve) the Agreement and the Proposed
Sale. Rather, the Board made its determination based on the total mix of
information available to it, and the judgments of the individual Directors may
have been influenced to a greater or lesser degree by different factors. In
considering the recommendation of the Board with respect to the Proposed Sale,
shareholders should be aware that the interests of certain Directors and
executive officers with respect to the Proposed Sale are or may be different
from or in addition to the interests of the Company's shareholders generally.
The Board was aware of these interests and took these interests into account.
 
OPINION OF FINANCIAL ADVISOR
 
     In connection with the Proposed Sale, the Company retained McDonald to
render an opinion as to the fairness, from a financial point of view, of the
consideration to be received by the Company in connection with the sale of the
Clinical Business. McDonald is an independent investment banking firm and is
actively engaged in the investment banking and brokerage business and regularly
undertakes the valuation of businesses in business combinations, public
offerings, private placements and similar transactions.
 
     McDonald has rendered its written opinion, dated December 21, 1998, to the
Board of Directors of the Company that, as of the date of the opinion and
subject to the assumptions, qualifications and limitations set forth in the
opinion letter and summarized herein, the consideration to be received by the
Company in the Proposed Sale is fair, from a financial point of view, to the
Company. McDonald's opinion is directed only to the fairness, from a financial
point of view, of the consideration to be received by the Company and does not
constitute a recommendation to any Collaborative shareholder as to how such
shareholder should vote on the Agreement. McDonald did not participate in the
determination of the purchase price to be paid to the Company in the Proposed
Sale.
 
     No limitations were placed by the Board of Directors or management of
Collaborative with respect to investigations made or the procedures followed by
McDonald in preparing and rendering its opinion. A copy of
 
                                       15

the full text of the opinion of McDonald, which sets forth the assumptions made,
a description of the factors considered and the scope of the review undertaken,
is attached as Appendix B to this Proxy Statement. McDonald has consented to the
use of its opinion in this Proxy Statement. The following summary of McDonald's
opinion is qualified in its entirety by reference to the full text of that
opinion. As set forth therein, McDonald relied, without independent
verification, upon the accuracy and completeness of all information reviewed by
it for the purposes of such opinion. McDonald did not conduct a physical
inspection of the properties and facilities of the Clinical Business nor did it
make or obtain an independent appraisal of the assets of the Clinical Business.
 
     In connection with the review of the Agreement and the Proposed Sale, and
the preparation of its opinion, McDonald examined: (1) historical financial
statements of Collaborative and certain financial forecasts and other data
provided by Collaborative's management; (2) certain publicly available business
and financial information relating to the contract research organization
industry; (3) the financial terms of the Agreement and the Proposed Sale; (4)
current and historical market prices and trading volumes of Collaborative's
Common Shares; (5) historical and projected revenue and earnings of
Collaborative; (6) backlog information and (7) certain other publicly available
financial information. McDonald also met with certain officers and employees of
Collaborative to discuss the business and prospects of Collaborative as well as
other matters that it believed relevant to its inquiry.
 
     In McDonald's review and analysis, and in arriving at its opinion, McDonald
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided to it or made publicly available and assumed and
relied upon the representations and warranties of the Company and West contained
in the Agreement. McDonald was not engaged to, and did not independently attempt
to, verify any of such information. McDonald also relied upon Collaborative's
management as to the reasonableness and achievability of the financial and
operating projections (and the assumptions and bases therefor) provided to it
and, with the Company's consent, assumed that such projections reflect the best
currently available estimates and judgments of the Company's management and that
such projections and forecasts will be realized in the amounts and in the time
periods currently estimated by management. McDonald was not engaged to assess
the achievability of such projections or the assumptions on which they were
based and expressed no view as to such projections or assumptions. In addition,
McDonald did not conduct an evaluation or appraisal of any of the assets,
properties or facilities of Collaborative nor was it furnished with any such
evaluation or appraisal. McDonald also assumed that the conditions to the
transaction as set forth in the Agreement would be satisfied and that the sale
of the Clinical Business would be consummated on a timely basis in the manner
contemplated by the Agreement.
 
     The following is a summary of the financial and other analyses performed by
McDonald in connection with its opinion.
 
     Comparable Company Analysis. McDonald compared selected historical and
projected market value multiples of ten publicly traded contract research
organizations that it deemed to be comparable to the Clinical Business (the
"Peer Group"). For its comparable company analysis, McDonald selected public
companies that provide pharmaceutical and biotechnology outsourcing services.
The companies included in the Peer Group were Applied Analytical Industries,
Inc., BioReliance Corporation, ClinTrials Research Inc., Covance Inc., ICON
Plc., Kendle International Inc., PAREXEL International Corporation,
Pharmaceutical Product Development, Inc., Premier Research Worldwide, LTD. and
Quintiles Transnational Corp. No company used in McDonald's analysis was
identical to the Company. Accordingly, McDonald considered the market multiples
for the composite of comparable companies to be more relevant than the market
multiples of any single company.
 
     McDonald's analysis of the value the Company as compared to the Peer Group
included a comparison of the ratios of certain items of each company's income to
its enterprise value. A company's enterprise value is its value, on a debt-free
basis, as reflected by the stock market and is calculated by adding its market
capitalization (the total number of shares outstanding multiplied by share
price) and its debt, and subtracting its cash and cash equivalents. When
expressed as a multiple of such readily determinable income items, such as net
income, sales, earnings before interest and taxes ("EBIT") or earning before
interest, taxes,
 
                                       16
<PAGE>   23
 
depreciation and amortization ("EBITDA"), enterprise value can be employed as a
significant basis for measuring the relative value between comparable companies.
 
     Because the Company did not achieve positive net income, EBIT or EBITDA in
its last twelve month ("LTM") period, the ratios of a Peer Group company's
enterprise value to its EBIT and EBITDA were deemed not to be meaningful.
 
     The $15.0 million consideration to be paid to the Company for the assets of
the Clinical Business is 1.15x the Clinical Business's LTM sales. McDonald
concluded that the consideration to be paid was fair, from a financial point of
view, in part because the 1.15x ratio was greater than the median ratio of
enterprise value to LTM sales for the five Peer Group companies with
characteristics most like those of the Company. In their entirety, the companies
in the Peer Group had multiples of enterprise value to LTM sales of 0.4x to 8.1x
with a median of 2.3x. The range of these multiples among the Peer Group
companies varied widely. In general, companies with multinational operations,
larger market capitalizations and a history of profitability traded at higher
enterprise value to LTM sales multiples than the Peer Group median. The median
of the five Peer Group companies with smaller market capitalization had a ratio
of enterprise value to LTM sales of 1.0x. BioReliance, ClinTrials and Premier,
the three companies in the Peer Group with the least market capitalization, had
enterprise values of 1.0x, 0.4x and 0.6x LTM sales, respectively. It is
McDonald's opinion that the financial and operating characteristics of the
Company are more similar to the five Peer Group companies, which had a median
ratio of enterprise value to LTM sales of 1.0x, than to the large, profitable
multi-national contract research organizations, which had higher ratios of
enterprise value to LTM sales. On this basis, the $15.0 million consideration to
be paid was deemed fair because it reflected an enterprise value that was higher
than the median enterprise value of the five Peer Group companies closest in
relative comparison to the Company.
 
     McDonald's analysis also included a measure of relative value based upon
the ratio of each company's market value (its market capitalization) to its book
value. A company's book value is equal to the its total assets minus its total
liabilities. After the consummation of the Proposed Sale, the Company will
retain its cash and cash equivalents. Consequently, the book value of the Peer
Group companies was adjusted downward by an amount equal to the cash and cash
equivalents reflected on their respective balance sheets in order to provide
meaningful comparisons between the companies' market value to book value ratios.
 
     The market value to book value ratio of the Peer Group companies ranged
from 0.5x to 7.7x LTM sales with a median of 3.8x LTM sales. When cash and cash
equivalents are excluded from book value, the market value to adjusted book
value of the Peer Group ranges from 0.6x to 22.1x LTM sales with a median of
5.4x LTM sales. The purchase price of the Clinical Business is 0.5x book value
of the Company (including cash, cash equivalents and assets not included in the
purchase) and 7.8x adjusted book as described above. In other words, when
expressed as a multiple of book value, the purchase price of the Clinical
Business is substantially higher than the median of the Peer Group companies
after adjusting for the fact that the Company will retain its cash and cash
equivalents as part of the Proposed Sale, thereby supporting McDonald's fairness
analysis.
 
     Analysis of Selected Acquisition Transactions. According to McDonald's
research, the Peer Group companies were involved in 13 acquisition transactions
collectively in 1998 and 25 acquisition transactions in 1997. Of those, three
transactions in 1998 and four transactions in 1997 involved target CRO's that
have characteristics similar to Collaborative's Clinical Business. Although
information about those transactions is less readily available than information
about larger transactions, McDonald sought out information about those smaller
transactions for purposes of its acquisition transactions analysis.
 
     McDonald analyzed the multiples of LTM sales represented by the purchase
price paid in the acquisition transactions it reviewed. Sales multiples ranged
from approximately 1.0x to 3.3x with a median of 1.8x. The purchase price to be
paid for the Clinical Business by West represents a multiple of 1.15x LTM sales,
which is within the range of multiples of comparable acquisition transactions.
 
     Other Matters. No company or transaction used in the above analyses for
comparative purposes is identical to the Company. Accordingly, an analysis of
the results of the foregoing necessarily involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the
 
                                       17
<PAGE>   24
 
companies and other factors. For example, McDonald analyzed the projected
revenue growth rate of the pharmaceutical outsourcing industry and 1999 revenue
growth rate forecasts for the Peer Group companies. In addition, McDonald
analyzed the relationship between the year end backlog of the Peer Group
companies and their subsequent realized revenues. These analyses were then
compared with enterprise values of the Peer Group companies and the Clinical
Business. Mathematical analysis (such as determining the median) is not, in
itself, a meaningful method of using comparable company or transaction data.
 
     While the summary of the analyses set forth above does not purport to be a
complete description of the analyses conducted by McDonald, all material
analyses conducted by McDonald for the purpose of rendering its opinion have
been described above. The preparation of a fairness opinion is not necessarily
susceptible to partial analysis or summary description. McDonald believes that
its analyses and the summary set forth above must be considered as a whole and
that selecting portions of its analyses, without considering all analyses, or of
the above summary, without considering all factors and analyses, would create an
incomplete view of the process underlying the analyses set forth in McDonald's
opinion. In addition, McDonald may have deemed various assumptions more or less
probable than other assumptions, so that the ranges of valuations resulting from
any particular analysis described above should not be taken to represent the
actual value of the Clinical Business.
 
     The term "fair, from a financial point of view," is a standard phrase
contained in investment banking fairness opinions and refers to the fact that
McDonald's opinion is addressed solely to the financial attributes of the
consideration to be paid in connection with the Proposed Sale. In performing its
analyses, McDonald made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of the Company. The analyses performed by McDonald
are not necessarily indicative of actual values or actual future results, which
may be significantly more or less favorable than suggested by such analyses.
Such analyses were prepared solely as part of McDonald's analysis of the
fairness of the consideration to be paid pursuant to the Agreement. The analyses
do not purport to be appraisals or to reflect the prices at which a company
might actually be sold or the prices at which any securities may trade at the
present time or at any time in the future. In addition, as described above,
McDonald's opinion to the Board was one of many factors taken into consideration
by the Board in making its determination to approve the Agreement. Consequently,
the McDonald analyses described above should not be viewed as determinative of
the Board's conclusions with respect to the value of the Clinical Business.
 
     During the December 21, 1998 meeting of the Board of Directors of the
Company, McDonald delivered its oral opinion that, as of the date thereof, and
subject to the assumptions, qualifications and limitations provided, that the
consideration to be received by the Company upon the consummation of the
Proposed Sale was fair, from a financial point of view to the Company.
 
     McDonald has expressed no opinion as to the prices at which the Company's
shares may trade following the date of its opinion.
 
     For rendering its opinion, Collaborative paid McDonald a retainer fee of
$25,000 and a further fee of $100,000 payable upon the delivery of the opinion.
McDonald has previously provided investment banking services to the Company for
which it has received customary compensation. The Company also agreed to
reimburse McDonald for its reasonable out-of-pocket expenses and to indemnify
McDonald and its affiliates against certain liabilities, including liabilities
under federal securities laws relating to or arising out of McDonald's
engagement to render its opinion.
 
POSITIVE AND NEGATIVE ASPECTS OF THE PROPOSED SALE
 
     The Proposed Sale provides benefits to the Company by enabling it to sell
its Clinical Business. The Clinical Business has not been a source of growth for
Collaborative in recent years. The Board of Directors believes that a larger,
more established company, such as West, could realize the growth potential of
the Clinical Business. The Board of Directors further believes that DataTRAK
offers greater opportunities for future growth for a company such as
Collaborative. In addition, the cash proceeds to the Company generated by the
Proposed Sale and certain of the Company's retained assets provide it with
significant cash resources to
 
                                       18
<PAGE>   25
 
use in its efforts to expand DataTRAK without diluting the ownership interest of
the Collaborative shareholders. The Proposed Sale will also permit Collaborative
to focus its management and financial resources on the growth opportunities
presented by DataTRAK.
 
     There are also negative aspects to the Proposed Sale. Subsequent to the
Proposed Sale, approximately 95% of the Company's assets, or approximately $40.0
million, will be held in cash, cash equivalents and short-term investments. The
Company's only has a small number of contracts related to its DataTRAK
operations and has not generated more than a small amount of revenue from
DataTRAK ($130,000 for the year ended December 31, 1998). Moreover, there can be
no assurance that DataTRAK will ever generate revenue at a sustainable level or
that it will even be profitable. Consequently, subsequent to the Proposed Sale,
the Company's revenue base will be significantly smaller than in the past, and
it will be required to effectively absorb corporate overhead and other fixed
costs in order to succeed in the Company's efforts to profitably expand
DataTRAK. While the Company has made significant investments in establishing an
infrastructure to support DataTRAK, it has not previously operated in the EDC
business as an independent enterprise. In that regard, one of the Board's
concerns is whether DataTRAK has matured sufficiently to operate independent
from the Clinical Business or any other business in the clinical research
market. The Board anticipates that DataTRAK's operating results will fluctuate
significantly from period to period, and there can be no assurance as to
DataTRAK's future prospects. Although the Company believes DataTRAK's growth
prospects are attractive, it has only operated DataTRAK in its current form
since January 1998, and the Company's management has less experience in
operating that business than it had in operating the Clinical Business.
 
     While the Proposed Sale will provide the Company with significant
additional cash resources, applicable purchase price adjustment provisions may,
under certain circumstances, reduce the net amount actually received by the
Company or require the Company to return a portion of that cash to West
subsequent to the Closing. Based on the Clinical Business's net working capital
at December 31, 1998, it is currently estimated that the net amount received by
the Company will be increased by a $13,000 working capital adjustment and offset
by applicable transaction costs of $1.2 million. The actual proceeds received by
the Company in the Proposed Sale will depend on the Clinical Business's net
working capital as of the closing date, and on collections of accounts
receivable during the 180 days following the closing date. In addition, the
Agreement provides that the Company will have indemnity obligations to West
subsequent to the Proposed Sale. Although the Company does not believe that
these obligations will have a material adverse effect on its future results of
operations, there can be no assurance to that effect.
 
     Subsequent to the Proposed Sale, the Company may be required to voluntarily
delist its Common Shares from quotation and trading on the Nasdaq National
Market, which may significantly impair the liquidity of the trading market for
and the trading price of the Company's Common Shares. Upon the consummation of
the Proposed Sale, the scale of the Company's operations will be significantly
reduced. There can be no assurance that the Company will be able to maintain
continued compliance with Nasdaq's listing requirements or that Nasdaq will not
request the Company to voluntarily delist its securities from the National
Market System. Moreover, if the Company decides to repurchase a portion of its
outstanding Common Shares, a delisting of the Common Shares may reduce the price
at which shareholders may sell their Common Shares to the Company. If the
Company's Common Shares are no longer listed on the Nasdaq National Market, they
may be traded over-the-counter, or the Company may apply for listing of the
Common Shares on the Nasdaq SmallCap Market, subject to Nasdaq's approval.
 
INTERESTS OF CERTAIN PERSONS IN THE PROPOSED SALE
 
     The Company's stock option plans provide that all outstanding options,
including unvested stock option awards held by the Company's Directors and
executive officers, will become fully vested and exercisable upon a change in
control of the Company. Under such stock option plans, the consummation of the
Proposed Sale will constitute a change of control. The number of stock options
to acquire Collaborative Common Shares that are expected to become fully vested
and exercisable as a result of the consummation of the Proposed Sale held by
each Director and executive officer of the Company is as follows: Dr. Green,
18,750 shares; Mr. Black, 10,000 shares; Mr. Chassainge, 20,000; Mr. Folz, 5,050
shares; Mr. Hugill, 37,500 shares; Dr. Kasmer, 10,750 and Dr. Stigelman, 8,750.
On September 17, 1998, the Board adopted an amendment to the Amended and
Restated 1996 Outside Directors Stock Option Plan, as amended (the "Plan"),
under the terms of which,
 
                                       19
<PAGE>   26
 
among other things, each non-employee Director received an option to purchase
10,000 Common Shares at an exercise price of $4.19 per share. Those awards are
subject to shareholder approval of the amendment to the Plan, and are scheduled
to vest over a three year period. If the Proposed Sale is completed and the
amendment to the Plan is adopted, options to purchase 10,000 Common Shares
awarded to each of Messrs. Biro, Harris and Flaherty and Drs. Ratain, Stote,
Stoll and Walton will become fully vested and exercisable.
 
     In addition, the Compensation Committee of the Company's Board of Directors
has determined that, upon the consummation of the Proposed Sale pursuant to the
terms described in the Agreement, Mr. Hugill will be paid a cash bonus of
$20,000.
 
     As a condition to the Proposed Sale, Dr. Green has entered into a two-year
non-competition agreement with West whereby Dr. Green has agreed not to engage
in the contract clinical research business or related activities. See "Proposal
to Approve the Sale of the Clinical Business -- Description of the Agreement and
the Proposed Sale; Non-Competition Agreement."
 
DESCRIPTION OF THE AGREEMENT AND THE PROPOSED SALE
 
     Purchase Price. The Agreement provides that, in consideration of the
transfer to West of all of the "Acquired Assets" (which include substantially
all of the assets relating to the Clinical Business), West has agreed to pay to
Collaborative in cash an amount (the "Purchase Price") equal to $15.0 million
plus or minus adjustments reflecting the value of the net working capital of the
Clinical Business on the Closing Date (defined below) and the ultimate value of
the net accounts receivable of the Clinical Business that are collected within
180 days after the Closing Date. On a pro forma basis at December 31, 1998
(exclusive of the collection of net accounts receivable), such adjustments would
have resulted in an increase in the purchase price of approximately $13,000. The
actual proceeds received by the Company in the Proposed Sale will depend on the
Clinical Business's net working capital as of the closing date and on
collections of accounts receivable during the 180 days following the closing
date. The Company anticipates the payment of an estimated $1.2 million in
transaction costs after consummation of the Proposed Sale. In addition, West has
agreed to assume certain liabilities arising from the Clinical Business.
 
     Fifteen days prior to the Closing Date, Collaborative and West will
calculate an "Estimated Closing Date Net Working Capital" based upon the
Company's financial statements as of the date of the calculation. The Estimated
Closing Date Net Working Capital will (if positive) be added to or (if negative)
be subtracted from the $15.0 million base purchase price to form the "Estimated
Purchase Price." At the Closing Date, West will deliver to Collaborative the
Estimated Purchase Price less $1.0 million. On such date, West will also deliver
$1.0 million to the escrow agent.
 
     Within 60 days after the Closing Date, West will prepare a statement (the
"Final Closing Date Statement") of acquired assets and assumed liabilities
setting forth West's calculation of the net working capital of the Clinical
Business as of the Closing Date (the "Closing Date Net Working Capital"). Upon
completion of the Final Closing Date Statement, West will deliver a copy to
Collaborative. Collaborative will have 15 days to review the Final Closing Date
Statement and accept or reject West's calculation of the Closing Date Net
Working Capital. Collaborative and West will thereupon have three days within
which to resolve any disagreement they may have over the amount. If they cannot
agree upon a Closing Date Net Working Capital within three days, Collaborative
and West will submit their disagreement to an independent certified public
accounting firm for resolution within 15 days from the date of submission. Such
firm's determination of the Closing Date Net Working Capital will be final and
binding upon Collaborative and West.
 
     At a supplemental closing, to be held within 90 days after the Closing Date
or ten days after the determination of the Closing Date Net Working Capital,
Collaborative will pay to West or West will pay to Collaborative, as
appropriate, the difference between the Estimated Purchase Price and the
Purchase Price based upon the final Closing Date Net Working Capital. If such
Purchase Price exceeds the Estimated Purchase Price, the excess amount will be
paid by West to Collaborative. If such Purchase Price is less than the Estimated
Purchase Price, the difference will be paid to West from the funds held in
escrow, with any amount greater than the amount held in escrow to be paid
directly by Collaborative.
 
                                       20
<PAGE>   27
 
     In addition to adjustments reflecting net working capital of the Clinical
Business on the Closing Date, the Purchase Price will be adjusted positively or
negatively to reflect the ultimate value of net accounts receivable collected
within 180 days after the Closing Date.
 
     The Closing. It is anticipated that the closing of the Proposed Sale will
take place on or about April 16, 1999 (the "Closing Date"), subject to approval
of the Proposed Sale by the Collaborative shareholders and the termination of
the applicable waiting period provided for under United States antitrust laws
and regulations. The Closing Date must occur no later than April 30, 1999,
following which date either party may terminate the Agreement.
 
     Acquired Assets and Assumed Liabilities. The Acquired Assets generally
include all of the assets of the Clinical Business that constitute the operating
assets of the Clinical Business, including, without limitation, accounts
receivable, tangible personal property, assigned contracts, claims, prepayments,
deposits, books and records, advertising, permits and licenses and intellectual
property (including, without limitation, the names "Collaborative Clinical
Research," "GFI Pharmaceutical Services" and "WCE Clinical Evaluations" and
derivations thereof).
 
     On the Closing Date, West will assume the following "Assumed Liabilities:"
(1) all obligations of Collaborative under the assigned clinical contracts that
are to be performed after, and relate to the period after, the Closing Date; and
(2) all accrued expenses and accounts payable as of the Closing Date arising in
the ordinary course of the Clinical Business.
 
     On the Closing Date, Collaborative will assign, and West will assume,
certain contracts relating to the operation of the Clinical Business (the
"Assumed Contracts"). In general, West will perform all post-closing obligations
and realize all post-closing benefits under the Assumed Contracts, subject to
the terms of the Agreement.
 
     On the Closing Date, Collaborative will retain, and West will not acquire,
the following "Excluded Assets:" (1) all cash and cash equivalents (including
marketable securities); (2) the corporate charters, qualifications to conduct
business as foreign corporations, taxpayer and other identification numbers,
minute books, seals and other records relating to the maintenance and existence
of Collaborative, GFI and WCE, as corporate entities; (3) all rights under the
Agreement; (4) all assets not related to the Clinical Business; (5) the Common
Shares of DataTRAK, Inc.; (6) Collaborative's tax returns and related corporate
records; (7) all information protected by Collaborative's attorney-client or
attorney work product privilege; (8) claims and similar rights of Collaborative,
GFI and WCE against third parties that are not related to the Clinical Business;
and (9) certain shared assets to be determined by the parties. Except as
otherwise provided in the Agreement, West will not assume any liabilities of
Collaborative of any nature, currently existing or incurred in the future, that
are not expressly included within the definition of Assumed Liabilities.
 
     Representations and Warranties. The Agreement contains certain customary
representations and warranties from each of the parties. The Company made
representations regarding, among other things, (i) its authority to enter into
and perform its obligations under the Agreement; (ii) its organization and good
standing; (iii) compliance of the transactions contemplated by the Agreement
with the Company's Articles of Incorporation, Code of Regulations, certain
agreements and applicable laws; (iv) the financial statements of the Company as
of December 31, 1997 (audited) and as of September 30, 1998 (unaudited); (v) the
Company's title to the assets to be sold and the absence of any encumbrances
impairing such title; (vi) the condition and sufficiency of such assets; (vii)
the absence of any undisclosed liabilities; (viii) taxes; (ix) employment
relations and benefits; (x) compliance with legal requirements, governmental

that may interfere with the Proposed Sale; and brokers' or finders' commissions
or fees.
 
     Conditions to the Proposed Sale. The obligations of West to close the

condition or circumstance will have occurred that could reasonably be expected
to result in such a material adverse change; (10) Collaborative will have
delivered to West any supplement to certain schedules relating to changes in the
business; and (11) Collaborative will have delivered to West, within five days
prior to the Closing Date, true, correct and complete copies of all affiliated
site contracts then in effect.

     Non-Solicitation Provisions. The Agreement prohibits Collaborative from
directly or indirectly soliciting, initiating or encouraging any acquisition
proposals with respect to the Clinical Business. Collaborative can engage in
negotiations or soliciting proposals concerning a possible transaction involving
DataTRAK or the assets not included in the sale. In addition, the Company is
entitled to respond to an unsolicited request for information concerning
Collaborative and, if after consultation with its legal counsel and financial
advisors, the Collaborative Board determines that a bona fide written proposal
represents a superior proposal to the Proposed Sale, the Company can pursue such
superior proposal. The Company is obligated to keep West informed as to the
status of any such proposal or inquiry. If the Company ultimately determines to
pursue the other proposal, the Collaborative Board may withdraw or modify its
approval of the Agreement and may enter into an agreement with respect to the
superior proposal. In such event, the Company would be required to pay West a
termination fee equal to $1.0 million plus West's expenses in connection with
the transaction (not to exceed a maximum of $200,000).
 
     Covenants Pending the Closing. Pursuant to the Agreement, Collaborative has
agreed, with respect to the Clinical Business: (1) to afford West and its
representatives full and free access to records and senior executive management;
(2) to operate in the ordinary course of business; (3) except as contemplated by
the Agreement, not to take any action or take any action outside of the ordinary
course of business; (4) to make all filings legally required to be made by
Collaborative and to cooperate with West with respect to all filings legally
required to be made by West; (5) to notify West if Collaborative becomes aware
of any fact that causes a breach of Collaborative's representations and
warranties under the Agreement; (6) to use its best efforts to cause the
satisfaction of the conditions in the Agreement that are required at or prior to
the Closing Date; (7) to pay one half of all fees associated with compliance
under the United States antitrust laws and
 
                                       22

deliver a voting agreement in the form specified in the Agreement; and (12) to
take all action necessary to hold a meeting of shareholders to consider and vote
upon the approval of the Agreement and the Proposed Sale.
 
     The Agreement requires West: (1) to cause the filing of all legally
required documents necessary to consummate the Proposed Sale; and (2) to use its
best efforts to cause the satisfaction of the conditions contained in the
Agreement that are required at or prior to the Closing Date.
 
     Indemnification. The Company has agreed to indemnify and hold harmless West
and its representatives and affiliates from and against any and all losses,
liabilities, claims, damages and expenses arising from or in connection with:
(1) any breach of any representation or warranty made by Collaborative in the
Agreement; (2) any breach of any covenant or obligation of Collaborative made in
the Agreement; (3) all liabilities that are not Assumed Liabilities; (4) any
environmental, health and safety liabilities arising out of or relating to the
ownership or operation of any acquired real properties; (5) any claim by any
person for brokers' or finders' commissions or fees; and (6) any claims arising
from violations of laws relating to bulk transfers.
 
     West has agreed to indemnify and hold harmless Collaborative from any
damages arising from or in connection with: (1) any breach of representation or
warranty made by West in the Agreement; (2) any breach of any covenant or
obligation of West in the Agreement; and (3) any claim by any person for
brokers' or finders' commissions or fees.
 
     The Company's indemnification obligations are subject to certain
limitations, including (i) that the representations and warranties and the
related indemnification obligation will expire six months following the Closing
Date, with the exception of damages incurred through excluded liabilities; (ii)
a $100,000 threshold liability; and (iii) a maximum liability of $1.0 million.
The threshold and maximum on the Company's indemnification obligations are not
applicable, however, in the event that West suffers loss or damage by reason of
a Company liability which West did not agree to assume.
 
     Termination. The Agreement may be terminated and the Proposed Sale may
thereby be abandoned at any time prior to the Closing Date: (1) by either party
if a material breach of any provision of the Agreement has occurred and has not
been waived or cured within 15 days; (2) by West if any of the conditions
required to be satisfied by Collaborative at or prior to the Closing Date has
not occurred or the satisfaction of such condition has become impossible; (3) by
Collaborative if any of the conditions required to be satisfied by West at or
prior to the Closing Date has not occurred or the satisfaction of such condition
has become impossible; (4) by mutual consent of Collaborative and West; (5) by
Collaborative if deemed necessary in connection with the acceptance of a
superior proposal; and (6) by either party if the Proposed Sale is not
consummated on or before April 30, 1999. If the Agreement is terminated by
Collaborative in connection with the acceptance of a superior proposal,
Collaborative will pay to West a termination fee of $1.0 million and will
reimburse West for all reasonable out-of-pocket expenses up to a total amount
equal to $200,000.
 
     Non-Competition Agreement. As a condition to the Proposed Sale, the
Company, DataTRAK and Dr. Green have entered into a non-competition agreement
(the "Non-Competition Agreement") whereby the Company, DataTRAK and Dr. Green
has each agreed not to engage in the contract clinical research business or
related activities (subject to certain exceptions in the case of Dr. Green). The
term of the Non-Competition Agreement between the Company, DataTRAK and West
will be three years from the Closing Date. The term of the Non-Competition
Agreement between Dr. Green and West will be two years. The Non-Competition
Agreement will not restrict the Company's EDC operations.

EXPECTED GAIN FROM PROPOSED SALE; CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Upon completion of the Proposed Sale, the Company expects to report a gain
of approximately $11.0 to $12.0 million, subject to certain post-closing
adjustments. Any adjustment for the collection of net accounts receivable will
be accounted for as a change in accounting estimate and will be recognized as an
adjustment to the Company's results of operations in the time period that such
amount, if any, is determined. Amounts paid by West to the escrow agent will be
recorded by the Company as restricted cash. The Company does not anticipate
federal income tax liability as a result of the reported gain due to the
Company's large net operating loss carryforwards.
 
ACCOUNTING TREATMENT
 
     The sale of the Clinical Business will be accounted for by the Company as a
sale of assets.
 
RECOMMENDATION; REQUIRED VOTE
 
     THE COLLABORATIVE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE AGREEMENT. THE AFFIRMATIVE
VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING COMMON SHARES OF THE
COMPANY IS REQUIRED TO APPROVE AND ADOPT THE AGREEMENT.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
GENERAL
 
     Collaborative operates two separate businesses within the clinical research
industry. Through its Clinical Business, the Company operates a multi-specialty
site management organization ("SMO") that provides clinical research services to
companies in the clinical pharmaceutical, biotechnology, contract research
organization ("CRO") and medical device research industries (collectively
"Sponsors"). Through DataTRAK, the Company provides EDC and other services to
assist Sponsors in accelerating the completion of clinical trials. DataTRAK had
no revenue prior to 1998.
 
     On December 21, 1998, the Company signed the Agreement with West providing
for the sale of assets of the Company related to the Clinical Business. The sale
is subject to shareholder approval and, if approved, is expected to be completed
by the end of April 1999. Upon completion of the Proposed Sale, the Company will
no longer operate the Clinical Business.
 
     The Proposed Sale would transfer substantially all of the Company's backlog
to West, and the Company would no longer generate revenue from the operation of
the Clinical Business. Consequently, after the Proposed Sale, the DataTRAK
business will be the sole source of the Company's revenue, and approximately 95%
of the Company's assets, or approximately $40.0 million, will be held in cash,
cash equivalents and short-term investments. After the Proposed Sale, the
Company anticipates that DataTRAK's operating results will fluctuate
significantly from period to period. There can be no assurance of DataTRAK's
future prospects.
 
     The discussion that follows highlights the business conditions and certain
financial information specific to each of the Company's two business segments.
 
     Clinical Business. The Clinical Business provides services to three
segments of the pharmaceutical and biotechnology industries. Through WCE, it
provides clinical research services relating to the reclassification of
prescription drugs into drugs available for OTC purchase and other OTC clinical
research services. In addition, the Clinical Business provides Phase I research
services from its 80-bed clinic at GFI. Finally, through its Affiliated Site
Network which is comprised of six therapeutically focused sub-networks drawn
from over 450 affiliated research sites ("Affiliated Sites"), it provides Phase
II, III, and IV research services. The Company has no ownership interest in any
of its Affiliated Sites.
 
     The Clinical Business enters into contracts that 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, these 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. Pass-through costs that are paid directly by Sponsors,
and for which the Company does not bear the risk of economic loss, are excluded
from revenue. These clinical trial 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.
 
     Contracts in the Clinical Business may generally 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 net loss of the Clinical Business was $2.0 million, including a special
items charge of $260,000, for the year ended December 31, 1997 and $10.1 million
for the year ended December 31, 1998, including special items and impairment
charges totaling $7.3 million.
 
                                       25
<PAGE>   32
 
     The Company's backlog at December 31, 1998, substantially all of which
relates to the Clinical Business, was $15.8 million, as compared to backlog of
$25.9 million at December 31, 1997. During 1998, a large contract, which had not
been performing as expected, together with several smaller contracts were
removed from backlog. The removal of these contracts reduced backlog by $16.9
million. The current backlog reflects the addition of $19.0 million of new
backlog during 1998. Other miscellaneous contract adjustments had the effect of
increasing backlog by $1.0 million. Of the $15.8 million backlog at December 31,
1998, the Company expects that $10.4 million will be converted to revenue
subsequent to 1999.
 
     DataTRAK Business. Collaborative's wholly owned subsidiary, DataTRAK, uses
the software known as DataTRAK EDC(TM) to provide EDC and technology services to
Sponsors in order to assist in the more timely completion of clinical trials.
The Company is currently developing this business, has recognized minimal
revenue to date, and has experienced significant losses and negative cash flow
from operations since beginning operations in 1997. DataTRAK had no operating
results during 1995 or 1996. During the year ended December 31, 1997, DataTRAK
had no revenue and a net loss of $3.9 million, including a special items charge
of $2.7 million. For the year ended December 31, 1998, DataTRAK's net loss was
$2.7 million, including a special items charge of $161,000. There can be no
assurance that the Company will be successful in achieving commercial acceptance
of the DataTRAK(R) process.
 
     DataTRAK contracts provide a fixed price for each component or service to
be delivered. Services provided by DataTRAK that are in addition to those
provided for in its contracts are billed on a fee for service basis for services
completed. Generally, these contracts range in duration from twelve to eighteen
months. The ultimate contract value is dependent upon the length of the
customer's use of DataTRAK EDC(TM) and the services provided by DataTRAK. As
services are performed over the life of the contract, revenue is recognized
under the percentage of completion method utilizing units of delivery. Costs
associated with contract revenues are recognized as incurred. These contracts
can be terminated at any time by the Sponsor with or without cause. DataTRAK is
entitled to payment for all work performed through the date of notice of
termination and for recovery of some or all costs incurred to terminate a
contract. The termination of a contract will not result in a material adjustment
to revenue or costs previously recognized.
 
     DataTRAK is also a seller and licenser of software. Generally, revenue is
recognized upon delivery of sold software. Licensing revenue is recognized
ratably over the life of the license. To date DataTRAK has not recognized any
revenue from software sales.
 
     Since its purchase of the DataTRAK EDC(TM) software, in January 1998,
DataTRAK has recorded fee for service revenue related to two fixed unit price
clinical trial contracts. At December 31, 1998, DataTRAK's backlog, related to
one contract, was $30,000. In the future DataTRAK may also record revenue
related to the sales of software. Due to DataTRAK's early stage of development
and its low level of backlog, there can be no assurance as to its future levels
of revenue.

     During 1996, the Company's only line of business was the Clinical Business.
For comparative purposes, statement of operations items related to corporate
overhead have been shown in the "Other Corporate Items" column of the table for
the year ended December 31, 1996.
 
YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997
 
     Clinical Business. Revenue for the year ended December 31, 1998 decreased
24.3% to $13.1 million as compared to $17.3 million for the year ended December
31, 1997. The decrease was the result of a decline in revenue from clinical
trials conducted by the Clinical Business, caused by the inability to attract
sufficient new business and convert existing backlog into revenue during the
year ended December 31, 1998. During both 1997 and 1998 the Clinical Business
performed services on approximately 200 contracts. The size, duration and
difficulty of each contact varies, and therefore the amount of backlog converted
into revenue and revenue earned in any year is independent of the number of
contracts on which services are performed. During the second half of 1997, the
Company hired a new Vice President of Marketing and Sales and rebuilt its sales
force in an effort to increase backlog. In December of 1997, the Company hired a
Chief Operating Officer for the Clinical Business and a new General Manager for
GFI. During 1998, $19.0 million of new contracts was added to backlog, however,
due to the duration of many of these contacts, much of this new backlog was not
converted into revenue in 1998. The Clinical Business's backlog at December 31,
1998 was $15.8 million. The Company expects $5.4 million to be converted to
revenue in 1999. There can be no assurance as to the level of backlog that will
be added in 1999, or as to the Clinical Business's level of revenue in 1999 and
beyond.
 
     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 $2.6 million, or 20.6%, from $12.6 million to $10.0 million for the years
ended December 31, 1997 and 1998, respectively. As a percentage of revenue,
direct costs increased from 72.8% during the year ended December 31, 1997 to
76.3% during the year ended December 31, 1998. The Clinical Business incurs a
high level of fixed direct costs at its owned research sites, due to the number
of clinical and support personnel required in order to offer clinical services
at these sites. The increase in direct costs as a percentage of revenue was the
result of the division's low level of revenue and its inability to leverage
fixed costs at its Company-owned research facilities.
 
     Selling, general and administrative ("SG&A") expenses include all
administrative personnel costs, business development costs, and costs associated
with the growth and quality maintenance of the Affiliated Site network, and all
other expenses not directly chargeable to a specific contract. Approximately 5%
of the Clinical Business's SG&A expenses are for costs associated with the
growth and quality maintenance of the Affiliated Site network. These Affiliated
Site network costs, which include among other things expenses related to
personnel, travel, advertising, database management and regulatory compliance,
are expensed as incurred. SG&A costs for the year ended December 31, 1998
decreased $600,000 to $4.9 million as compared to $5.5 million during the year
ended December 31, 1997. Of this decrease $300,000 was the result of the Company
exiting its European and other strategic initiatives, which were intended to
increase the types of research services offered by the Clinical Business. The
remainder of the decrease was the result of the Company's reorganization in the
first quarter of 1998. As a percentage of revenue, SG&A expenses increased from
31.8% to 37.4% for the years ended December 31, 1997 and 1998, respectively. The
increase in SG&A expenses as a percentage of revenue was the result of the
Clinical Business's low level of revenue being unable to absorb its fixed
operating costs.
 
     During 1998, the Clinical Business recorded asset impairment charges of
$6.1 million related to the impairment of goodwill. Of this charge, $1.9 million
was related to goodwill written off related to two Clinical Business locations
that were closed in September 1998 due to poor operating performance. The $1.9
million of goodwill represents the unamortized portion of goodwill that was
allocated to these sites at the time of their purchase. The remaining $4.2
million of the impairment charge was for goodwill associated with GFI's
operations. GFI's revenue was in continual decline and its net losses continued
to increase since its acquisition. In the third quarter of 1998, after
management's efforts to effect a turn around were exhausted, and concurrent with
the Company's planning process, it was determined that the possibility of
recovering the recorded value of the GFI goodwill through a sale of GFI,
exclusive of a sale of the entire Clinical Business, was remote. In
 
                                       28
<PAGE>   35
 
addition, it was determined that GFI's future undiscounted cash flows were below
the carrying value of GFI's long-lived assets. Accordingly, during the third
quarter of 1998, the Company adjusted the carrying value of GFI's long-lived
assets to their estimated fair value of approximately $1.6 million, resulting in
the non-cash charge of $4.2 million. The estimated fair value was based on the
purchase price allocated to GFI pursuant to an initial offer from West to
purchase the Clinical Business. The write-downs of goodwill will result in a
reduction of the Clinical Business's depreciation and amortization expense by
approximately $230,000 as compared to 1998 expense levels.
 
     The Clinical Business incurred special items charges of $1.2 million for
the year ended December 31, 1998. Of this total, $810,000 was incurred as part
of the Company's reorganization plan and included severance costs for 19
employees who were terminated in March of 1998, costs associated with the
relocation of certain Clinical Business employees and costs related to a lawsuit
settlement with two former Clinical Business executive officers. The remaining
$430,000 was a result of the Company exiting its United Kingdom activities and
costs related to the closing of two of its Clinical Business sites. During 1997,
the Clinical Business had special items charges of $260,000 relating to the
disposal of certain medical equipment, computer equipment and the closing of a
leased facility. Management expects that these actions will lower the Clinical
Business's SG&A expenses by approximately $800,000 as compared to 1998 SG&A
expenses.
 
     Depreciation and amortization expense decreased from $820,000 for the year
ended December 31, 1997 to $690,000 during the year ended December 31, 1998.
Approximately $90,000 of the $130,000 decrease was the result of the goodwill
write-down, and the remainder was due to the disposal of certain assets at the
end of 1997.
 
     Other expenses for the year ended December 31, 1998 of $210,000 were
recorded as a result of costs incurred relating to the Proposed Sale of the
Clinical Business.
 
     Income tax expense for the Clinical Business was $140,000 for the year
ended December 31, 1997 and $80,000 for the year ended December 31, 1998. These
taxes were the result of state taxes incurred during both years.
 
     DataTRAK Business. During the year ended December 31, 1998 DataTRAK had
revenue of $130,000. This revenue was the result of EDC services preformed on
two European clinical trials. Direct costs of this revenue, mainly personnel
costs at DataTRAK's German subsidiary ("DataTRAK GmbH"), were $460,000 resulting
in a gross margin loss of $330,000. Prior to 1998 DataTRAK had recorded no
revenue or direct costs.
 
     SG&A expenses increased from $1.1 million to $1.8 million for the years
ended December 31, 1997 and 1998, respectively. Of this increase, $480,000 was
the result of expenses incurred by DataTRAK GmbH. DataTRAK GmbH was established
in January 1998 in connection with the purchase of the software known as
DataTRAK EDC(TM). The remainder of the increase, as well as the costs incurred
by DataTRAK GmbH, was the result of costs incurred for developing, testing and
marketing the DataTRAK(R) process and the DataTRAK EDC(TM) software.
 
     DataTRAK had special items charges of $160,000 during the year ended
December 31, 1998. Of these charges, $30,000 resulted from the Company's first
quarter 1998 reorganization and included severance costs for one employee who
was terminated. The remaining $130,000 related to costs associated with the
termination of the technology alliance agreement between the Company and IBM
Global Services ("IBM"). DataTRAK recorded a special items charge of $2.7
million during 1997 as a result of the termination of its agreement with IBM.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Year ended December 31, 1997 Compared with Year ended December 31,
1996; DataTRAK Business."
 
     Depreciation and amortization expense increased from $70,000 during the
year ended December 31, 1997 to $360,000 during the year ended December 31,
1998. The increase was the result of the purchase of the DataTRAK EDC(TM)
software, and other assets, as well as capitalized software development costs.
 
     Other Corporate Items. The Company recorded SG&A expenses of $3.4 million
and $2.2 million during the years ended December 31,1997 and 1998, respectively
that were not allocated to either of Collaborative's
 
                                       29
<PAGE>   36
 
operating divisions. Part of the decrease in these expenses is due to the
absence of $600,000 of expenses related to the termination of potential
acquisitions. The remaining $600,000 decrease was due to reduced personnel and
other costs resulting from the Company's reorganization in the first quarter of
1998.
 
     Corporate special items relating to the Company's first quarter 1998
reorganization totaled $590,000. These charges included severance costs for nine
employees who were terminated in March of 1998. It is expected that the first
quarter of 1998 reorganization will have the effect of reducing corporate
related SG&A expenses by $170,000 as compared to 1998 expense levels.
 
     Corporate-related depreciation expense was $120,000 and $110,000 during the
years ended December 31, 1997 and 1998, respectively.
 
     Other income decreased $210,000 for the year ended December 31, 1998
compared to the year ended December 31, 1997. The decrease was primarily the
result of a decrease in interest income caused by the Company's use of cash to
fund its operating losses and other working capital needs. This decrease was
partially offset by the termination of the Company's Health Research Innovations
L.L.C's. ("HRI") joint venture. The HRI joint venture, between the Company and
Pharmaceutical Marketing Services, Inc., was terminated during the second
quarter of 1997. During the year ended December 31, 1997, the Company's share of
the loss from this joint venture was $50,000.
 
     As a result of the Company's net operating loss for the year ended December
31, 1997, a $200,000 federal income tax benefit was recorded at December 31,
1997. This benefit represents the refund the Company received from its net
operating loss carryback for federal income tax purposes. Due to the Company's
net operating loss for 1998, no federal income tax provision was recorded. At
December 31, 1998, the Company has a net operating loss carryforward of
approximately $13.0 million, which will expire in the year 2013.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996
 
     Clinical Business. 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. During the second half of 1997, the Company hired a new Vice President of
Marketing and Sales and rebuilt its sales force in an effort to increase
backlog. In December of 1997, the Company hired a Chief Operating Officer for
the Clinical Business and a new General Manager for GFI.
 
     Direct 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 70.0% in 1996 to 72.8% 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.
 
     SG&A expenses increased by $1.5 million from $4.0 million in 1996 to $5.5
million in 1997. Of the $1.5 million increase, approximately $1.0 million was
incurred at acquired research facilities, and the remainder was due to growth of
the Clinical Business's infrastructure. As a percentage of revenue, SG&A
expenses increased from 15.6% in 1996 to 31.8% in 1997. The increase in SG&A
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.
 
     Special items include charges of $260,000 related to the Clinical Business
that were recorded in the fourth quarter of 1997. These charges relate to the
disposal of certain medical equipment, computer equipment, and the closing of a
leased facility.
 
                                       30
<PAGE>   37
 
     Depreciation and amortization expense increased by $270,000 from $550,000
in 1996 to $820,000 in 1997. Of the $270,000 increase, $60,000 resulted from the
depreciation of assets acquired with GFI and WCE, $130,000 resulted from the
amortization of goodwill and $80,000 resulted from increased capital
expenditures.
 
     During 1997, the Clinical Business had state income tax expense of
$140,000.
 
     DataTRAK Business. During 1997, DataTRAK had SG&A expenses of $1.1 million.
These costs were related to the testing and Affiliated Site training of the EDC
and clinical trial management system, that was being developed through a
technology alliance agreement with ISSC, a unit of IBM Global Services and
DataTRAK. This technology agreement was terminated in 1997.
 
     During 1997, the Company and IBM disagreed on several issues relating to
the strategic direction of its technology alliance. In December of 1997, the two
parties determined these differences to be irreconcilable and the technology
alliance was terminated. As a result of this termination, the Company returned
the software that was developed as a result of this alliance to IBM. The
unamortized cost of this software, totaling $740,000 was written off. The
Company and IBM disagreed on a number of issues concerning the parties'
financial responsibilities in connection with the termination of the alliance,
and the Company recorded a $2.0 million charge, which represented its best
estimate at December 31, 1997 of its financial obligations associated with the
termination of the technology alliance. The total charge of $2.7 million was
recorded as part of special items expense for the year ended December 31, 1997.
 
     DataTRAK had depreciation expense of $70,000 in 1997 related to software
and licenses associated with the technology alliance agreement with ISSC, a unit
of IBM, and DataTRAK.
 
     Other Corporate Items. For the years ended December 31, 1996 and 1997, the
Company had SG&A expenses of $2.1 million and $3.4 million, respectively, that
were not related to either of Collaborative's operating divisions. Of the $1.3
million increase, $600,000 was for expenses related to the terminated
negotiations for potential acquisitions. The remainder of the increase was due
to the Company's strategic initiatives, primarily related to personnel and other
costs incurred as a result of the Company's initiative to acquire clinical
research sites.
 
     Unallocated depreciation and amortization was $60,000 and $120,000 for the
years ended December 31, 1996 and 1997, respectively. The increase was due to
increased capital expenditures, primarily related to computer systems.
 
     Other income increased from $1.0 million in 1996 to $1.9 million in 1997.
This was the result of a $790,000 increase in interest income on invested cash
(primarily the proceeds of the Company's initial public offering), and a $90,000
decrease in interest expense. Interest expense for 1996 was related 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 $30,000 increase in the
Company's share of HRI's net loss for the year ended December 31, 1997.
 
     As a result of the Company's net operating loss for the year ended December
31, 1997, a $200,000 federal income tax benefit was recorded at December 31,
1997. This benefit represents the refund the Company received from its net
operating loss carryback for federal income tax purposes. 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 resulted in $380,000 of income tax expense 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. All amounts received are recorded as a liability (deferred
 
                                       31
<PAGE>   38
 
revenue) until work has been completed and revenue is recognized. 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 $2.7 million at December
31, 1998 and $4.5 million at December 31, 1997. Deferred revenue was $630,000 at
December 31, 1998 and $850,000 at December 31, 1997.
 
     Cash and cash equivalents decreased $2.3 million during the year ended
December 31, 1998. This was the result of $4.5 million provided by investing and
financing activities, offset by $6.8 million used in operating activities.
Investing activities included net proceeds of $6.1 million from purchases and
maturities of short-term investments offset by $1.6 million used to purchase
property and equipment. Financing activities primarily consist of the collection
of a note receivable from an officer.
 
     Cash used for operating activities, of $6.8 million, resulted primarily
from the Company's net loss and other cash uses. Cash provided by operating
activities includes a $2.0 million decrease in receivables due to completion of
contracts and increased collection efforts in 1998. Cash used in operating
activities includes the Company's net loss, exclusive of non-cash operating
items, of $6.3 million. Other cash uses related to operating activities were
$2.1 million related to the termination of the DataTRAK alliance with IBM Global
Services, $820,000 paid for costs related to the Company's reorganization in the
first quarter of 1998 and $180,000 related to other special items charges.
Changes in other current assets and liabilities resulted in a net $600,000
source of cash.
 
     At December 31, 1998 the Company had working capital of $24.4 million, and
its cash, cash equivalents and short-term investments totaled $26.7 million. The
Clinical Business had working capital of $13,000 at December 31, 1998. The
Company's working capital decreased by $8.6 million from December 31, 1997. The
decrease was primarily the result of a $6.9 million decrease in cash, cash
equivalents and short-term investments, and the $2.0 million decrease in
receivables.
 
     The Company has a line of credit agreement with a bank, which provides for
borrowings up to $2.0 million and bears interest at rates not to exceed prime
(no amounts were outstanding at any time during 1998). The line of credit
agreement requires that the Company maintain investments of $2.0 million with
the bank. This line of credit is considered to be committed and is subject to
renewal at January 31, 2000.
 
     In connection with the sale of the Clinical Business, the Company will
receive $15.0 million. Based upon the Clinical Business's net working capital at
December 31, 1998, it is currently estimated that the $15.0 million purchase
price to be paid to the Company will be increased by a $13,000 working capital
adjustment and by offset by applicable transaction costs of $1.2 million. The
actual proceeds received by the Company in the Proposed Sale will depend on the
Clinical Business's net working capital as of the closing date, and on the
collection of net accounts receivable during the 180 days following the closing
date. The Company has not yet determined how those proceeds, as well as its
other cash, cash equivalents and short-term investments will be used. The Board
is considering numerous alternatives consistent with its objective to permit
shareholders to realize the value of the DataTRAK technology. Among them, the
Board is considering using some of the proceeds to provide working capital to
finance DataTRAK's development and expansion (either independently or in
conjunction with one or more strategic partners). It is also considering using a
portion of the proceeds to repurchase outstanding Common Shares. The Board is
also considering a possible sale or merger of the Company. However, the Company
is not currently engaged in any discussions or negotiations concerning a sale or
merger of the Company.
 
     Subsequent to the Proposed Sale, it is possible that the Company may be
required to voluntarily delist its Common Shares from quotation and trading on
the Nasdaq National Market, which may impair the liquidity of the trading market
for the Common Shares. However, if the Common Shares are delisted, the Company
may list its Common Shares for trading over-the-counter or may apply for listing
of the Common Shares on the Nasdaq SmallCap Market, subject to Nasdaq's
approval. The Company's liquidity and capital resources would not be materially
effected if it were required to voluntarily delist its Common Shares from
quotation and trading on the Nasdaq National Market. However, a delisting of the
Common Shares could have a long-term impact on the Company's ability to raise
future capital through a sale of its Common Shares.

     In January 1998, DataTRAK purchased the EDC software now known as DataTRAK
EDC(TM) from EDS for $610,000. The Company is responsible for funding the future
development and testing of this software. The Company will also continue to
invest in the development of the DataTRAK(R) process. DataTRAK's primary source
of cash has been cash generated by the Clinical Business and the maturities of
corporate short-term investments. DataTRAK has had a negative cash flow of
approximately $9.0 million since it began operations in 1997. The Company
anticipates that its cash needs for 1999 operations will be approximately $5.0
million, including $1.0 million related to the payment of special items charges
recorded in 1998. In addition, the Company anticipates software development
expenditures of $1.5 to $2.0 million over the next two years for continued
commercialization and product development of DataTRAK EDC(TM). The Company
expects such activities will be funded from existing cash and cash equivalents,
maturities of short-term investments, cash flow from operations, borrowings
under its line of credit, as needed, and the proceeds from the sale of its
Clinical Business.
 
YEAR 2000 READINESS DISCLOSURE
 
     Many existing computer systems and software programs currently in use are
coded to accept only two digit entries in the date code field. These systems and
programs were designed and developed without considering the impact of the
upcoming change in the century. If not corrected, many computer applications
could fail or create erroneous results by or at the Year 2000.
 
     The Company understands that as the new millennium approaches it is vital
to all of its Sponsors, Affiliated Sites and suppliers that Collaborative's
internal information technology ("IT") and non-IT systems are Year 2000
compliant. In addition, just as important a priority is the compliance of
external IT and non-IT systems and services provided by others to Collaborative.
To meet the above compliance requirements Collaborative has utilized the
following methodology since mid-1997. It has: (i) developed a three-year plan
(1997-1999) with Year 2000 IT issues as a priority, (ii) established a corporate
Year 2000 program, (iii) performed a physical inventory of all IT and non-IT
systems and software, (iv) delegated internal Year 2000 evaluation and testing
responsibilities within the Company, (v) assessed its compliance with the above
plans on an on-going basis, (vi) identified and categorized any "Mission
Critical" items, (vii) repaired or replaced all non-compliant IT and non-IT
systems and services, (viii) internally tested all systems and services for
compliance, (ix) compiled appropriate documentation of all testing and vendor
compliance statements, (x) queried its utilities, Sponsors, Affiliated Sites and
suppliers as to their readiness and status, (xi) developed a business
contingency plan in the event of Year 2000 malfunctions, and (xii) issued a
public Year 2000 disclosure statement on the Company's web site.
 
     The Company has also established internal policies that have actively
informed its employees of the Year 2000 problem and that assist in procurement
of only new equipment that is Year 2000 compliant.
 
     At this point in the Company's Year 2000 effort, substantially all of the
Company's internal IT and non-IT hardware and software systems have been tested
and either replaced or repaired. The Company expects that all other
non-compliant IT and non-IT systems will either be Year 2000 ready or replaced
by June 30, 1999. There can be no assurance that additional coding errors or
other defects will not be discovered in the future though management believes
the possibility of such discoveries is quite low due to the recent vintage and
uniformity of IT and non-IT systems throughout Collaborative.
 
     The Company is in the process of determining how it may be impacted by any
third parties' failure to remedy their own Year 2000 issues. The Company has
initiated formal communications with significant Sponsors, suppliers and other
third parties to determine the extent, if any, to which the Company's interface
systems could be impacted by those third parties' failure to remedy their own
Year 2000 issues. The Company will continue these communications through
mid-1999. Management currently does not anticipate any material adverse impact
on its operations as a result of Year 2000 issues of third parties. However, at
this stage of the review no assurance can be given that the failure by one or
more third parties to become Year 2000 compliant will not have a material
adverse impact on the Company's financial position or results of operations.
 
     Management of the Company believes an effective program for resolving Year
2000 issues in a timely manner is in place. Since it is not possible to
anticipate all possible future outcomes, especially when third
 
                                       33
<PAGE>   40
 
parties are involved, there could be circumstances in which the Company's
operations could be interrupted. In addition, disruptions in the economy in
general resulting from Year 2000 issues could also adversely impact the Company.
The most significant Year 2000 issue and worst case scenario of concern to the
Company has been identified as being a long-term electrical power disruption.
The Company's contingency plans for large-scale Year 2000 disruptions focuses on
two critical high-level operational issues: (i) The preservation and
availability of critical Company data as of December 31, 1999 and (ii) the use
of manual transaction processing until all disruptions are eliminated.
 
     To date, the total cost of the Year 2000 systems review has been immaterial
to the Company's financial position and results of operations. Management does
not anticipate incurring any additional costs that would be material to the
Company's financial position or results of operations. As of January 1999, the
Company has not utilized any outside consultants or technical staff to meet its
Year 2000 goals and has no current plans to do so.
 
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.

                          DESCRIPTION OF THE BUSINESS
 
THE COMPANY
 
     Overview of the Clinical Research Industry. The Company's DataTRAK and
Clinical Business serve companies in the clinical pharmaceutical, biotechnology,
CRO and medical device research industry. This industry is driven by regulatory
requirements that Sponsors adequately test new drugs and medical devices prior
to marketing. Competitive and cost-containment pressures are forcing the
pharmaceutical and biotechnology industries to become more efficient in
developing new products. To improve returns on research and development
investments, pharmaceutical and biotechnology companies are adding products to
their product pipelines and attempting to shorten the product development
timeline. These efforts have placed more drugs into the clinical development
process and have increased the pressure for Sponsors to develop products faster
in order 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.
 
     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.
 
     Employees. As of January 31, 1999, the Company had approximately 120
full-time employees. Upon the consummation of the Proposed Sale, the Company
will have 17 full-time employees, three of which will have 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 has employment agreements with all of its executives. The loss of
the services of any of these executives could have a material adverse effect on
the business or operations of the Company upon the consummation of the Proposed
Sale. To address these risks, the Company must, among other things, continue to
attract, retain and motivate qualified personnel. There can be no assurance that
the Company will be successful in addressing such risks.
 
     Properties. The Company presently maintains its executive, DataTRAK and
Affiliated Site Network offices in approximately 9,000 square feet of space in
Cleveland, Ohio pursuant to a lease with an unaffiliated third party. The
Company also maintains a lease for approximately 7,000 square feet of office
space in Bonn, Germany for its DataTRAK GmbH operations.
 
     The Clinical Business presently leases approximately 32,000 square feet of
office and medical space in Evansville, Indiana, housing, among other things, an
80 bed in-patient Phase I research facility for its GFI operations. WCE operates
from approximately 7,600 square feet of leased office space in Indianapolis,
Indiana. The Affiliated Site Network shares 9,000 square feet of leased office
space with the Company's corporate headquarters and DataTRAK operations in
Cleveland, Ohio. Upon completion of the Proposed Sale, the GFI and WCE leases
will be assigned to West. The Company will sublet to West approximately 4,500
square feet of office space in Cleveland, Ohio at terms substantially similar to
its current lease. The Company believes that the sublease arrangement with West
is adequate for its operations and suitable additional space will be available
when needed.
 
DATATRAK
 
     General. In 1996, Collaborative formed DataTRAK, Inc., a wholly owned
subsidiary. In January 1998, DataTRAK purchased the software now known as
DataTRAK EDC(TM) from PadCom. DataTRAK EDC(TM) was developed to provide clinical
research data faster and more efficiently than current information-processing to
Sponsors of clinical research trials. DataTRAK provides information-processing
capabilities designed for the clinical research environment through its EDC
technology and QRC process. 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 17,000 patients. To date, the Company has
devoted substantially all efforts related to DataTRAK to further developing and
improving the EDC technology employed by the DataTRAK software.
 
                                       35
<PAGE>   42
 
     DataTRAK Software and Services. Currently, clinical research associates
visit research sites to review data manually entered on the paper case report
form for accuracy and integrity. During these physical visits, the research
associate must review each page of each case report form. These monitoring
visits may last several days, and corrections to the case report forms are
frequently required before the data can be delivered 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 case report form pages are physically
transferred 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 nine months. Such delays are
significant because errors or trends may not be detected until long after the
interaction between patient and investigator.
 
     DataTRAK EDC(TM) is a technology platform that consists of Windows(TM)
compatible software and intranet hardware designed to assist Sponsors in
starting and finishing their clinical trials on a more timely basis. The
DataTRAK combination of software and hardware expedites the data collection and
reporting process during a clinical trial. In addition to providing the DataTRAK
technology, DataTRAK is also a service business that offers electronic data
collection and clinical trial data management capabilities across numerous
research sites. DataTRAK's objective is to improve the traditional process of
collecting clinical research and noninterventional health care data by providing
cleaner data more quickly than what is available in a paper environment.
 
     The DataTRAK system consists of five database modules designed for flexible
adaptation to the clinical research process. DataTRAK initially provides a set
of electronic data forms that can be modeled to suit the needs of the clinical
trial. Each form is then made available through data entry capability to each
research site. Once clinical trial data has been entered the data is processed
and reviewed either at DataTRAK's centrally located QRC or at the Sponsor. After
the data is reviewed and cleansed of all entry errors, DataTRAK's report
capability can be accessed by Sponsors and investigators to generate customized
reports.
 
     Finally, DataTRAK's export feature allows completed data and reports to be
transmitted directly to a Sponsor's in-house database.
 
     Under this model, research data is collected more quickly and with greater
accuracy than physical review of paper reports. The QRC largely replaces
traditional, paper-based forms of monitoring. Experienced clinical research
associates review the electronic data as it comes in to a central data
repository, reviewing medical alerts, protocol violations and recurring errors.
They review the incoming data for trends and communicate their findings
electronically to the clinical research site and/or the Sponsor. Once the case
report form data has been reviewed to correct errors it is integrated directly
into a Sponsor's database in Sponsor specified formats. Clinical trial data is
transmitted to DataTRAK's QRC or exported to a Sponsor's database via a global,
secure intranet. In 1998, the Company developed a web-compatible version of the
DataTRAK EDC(TM) software. To date, DataTRAK has not recognized any revenue from
its QRC services.
 
     In October 1998, an international pharmaceutical manufacturer presented
clinical metrics from its use of DataTRAK EDC(TM) in a multicenter,
international clinical trial involving 200 patients. Compared to a traditional
paper model in a similar trial of size and complexity, the clinical study showed
that DataTRAK EDC(TM) reduced overall trial duration by 30% and improved the
"cleanliness" of the data through a significant reduction in queries by 86%. The
Company believes that, by automating these procedures, the DataTRAK system can
be a timesaving component of the drug development process. DataTRAK can provide
any Sponsor or SMO with the DataTRAK process as a competitive advantage for
their clients by accelerating the review and processing of clinical trial data.
 
     Customers and Marketing. DataTRAK's market is largely comprised of
Sponsors. In connection with the Company's purchase of the software now known as
DataTRAK EDC(TM), the Company acquired agreements with a European Sponsor
licensing the use of DataTRAK EDC(TM) in a clinical trial presently underway in
Europe. Although the Company has not developed a defined marketing strategy, it
expects to market its software and services through DataTRAK's sales and
marketing staff located in the United States and Europe. Through DataTRAK's
marketing efforts, four large pharmaceutical companies have been identified who
are now seeking a worldwide EDC solution for their clinical trials. Since the
market for EDC in
 
                                       36
<PAGE>   43
 
general and for DataTRAK specifically has been an emerging one, the
effectiveness of DataTRAK's marketing efforts with Sponsors has been limited.
However, DataTRAK has selectively participated in scientific and medical
meetings to promote its services and has occasionally used direct mail and
journal advertisements to build awareness of its capabilities. During the year
ended December 31, 1998, Bayer accounted for all of DataTRAK's revenue totaling
$130,000.
 
     To assess the market potential of its DataTRAK EDC(TM) technology, the
Company hired an independent consulting firm, in August 1998 to perform a market
survey of pharmaceutical and biotechnology companies as to their interest in
adopting EDC for clinical trials. Thirty-five senior level personnel from
twenty-five companies participated in the survey, which was completed in October
1998. All but one participant agreed that EDC shortens the time required to
complete a clinical trial, saving between four and six weeks, not the
anticipated six months. Nineteen of the twenty-two respondents, from companies
currently without EDC capabilities, stated that their companies were going to
make a commitment towards EDC within the next twelve to twenty-four months. In
the survey, the majority of Sponsors believed that EDC will decrease the time
and cost of clinical research and development.
 
     The EDC market has been slow to develop. Most EDC vendors have
insignificant revenues and are classified as start-ups. The growth of the
Internet over the past two years has drastically altered business strategies and
pricing models in this specific sector. Nonetheless, the Company believes that
automation of some sort is inevitable, and that DataTRAK EDC(TM) can be
competitive in this emerging marketplace. The product is fully validated,
web-enabled, has multilanguage capability which has been utilized in actual
clinical trials, has been deployed in more than 30 studies involving a total of
17,000 patients, has international experience, and possesses sponsor-published
metrics documenting clinical trial acceleration and enhancement of quality
through significant reductions in queries.
 
     Contracting and Backlog. DataTRAK contracts provide a fixed price for each
component or service to be delivered. Services provided by DataTRAK that are in
addition to those provided for in its contracts are billed on a fee for service
basis for services completed. Generally, these contracts range in duration from
twelve to eighteen months. The ultimate contract value is dependent upon the
length of the customer's use of DataTRAK EDC(TM) and the services provided by
DataTRAK. As services are performed over the life of the contract, revenue is
recognized under the percentage of completion method utilizing units of
delivery. Costs associated with contract revenues are recognized as incurred.
These contracts can be terminated at any time by the Sponsor with or without
cause. DataTRAK is entitled to payment for all work performed through the date
of notice of termination and for recovery of some or all costs incurred to
terminate a contract. The termination of a contract will not result in a
material adjustment to revenue or costs previously recognized.
 
     DataTRAK is also a seller and licenser of software. Generally, revenue is
recognized upon delivery of sold software. Licensing revenue is recognized
ratably over the life of the license. To date DataTRAK has not recognized any
revenue from software sales.
 
     Backlog consists of anticipated revenue from letters of intent and signed
contracts yet to be completed. DataTRAK's backlog at December 31, 1998 was
$30,000. DataTRAK'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. The Company expects that the entire $30,000 backlog will be converted
to revenue during 1999.
 
     Competition. DataTRAK competes within the clinical research and the EDC
markets. Both of these industries are highly competitive and fragmented. In
addition, the EDC industry is currently emerging and is characterized by rapidly
evolving technology. The Company expects that DataTRAK will compete within this
market on the strength of its functionality, its design architecture and its
data entry and review tools, which the Company believes equal or exceed those
available in the market. The Company also believes that DataTRAK may enhance its
competitive strength through the formation of strategic alliances with
established industry organizations. While the Company has received expressions
of interest from various parties in establishing such relationships, it is not
engaged in any discussions concerning a sale or merger of the Company.
 
                                       37
<PAGE>   44
 
     DataTRAK's competitors within these fields consist of large, full-service
CROs, large information industry players and smaller, limited service providers.
DataTRAK's major competitors include software vendors specializing in EDC,
clinical trial data service companies and large pharmaceutical companies
currently developing their own in-house technology. Also, many current and
potential future competitors have or may have substantially greater financial
and technical resources, greater name recognition and more extensive customer
bases that could be leveraged, thereby gaining market share or product
acceptance to the Company's detriment. There can be no assurance that DataTRAK
will be able to capture or establish the market presence necessary to
effectively compete in this emerging sector of the clinical research industry.
 
     The Company is aware of other EDC systems that compete or, in the future,
may compete directly with DataTRAK EDC(TM). The Company is also aware of other
current or developing technologies that provide some of the functionality of the
DataTRAK process(R). There are other companies that have developed or are in the
process of developing technologies that are or, in the future, may be the basis
for competitive products in the clinical research EDC market. Some of those
technologies may have an entirely different approach or means of accomplishing
the desired effects of DataTRAK EDC(TM). There can be no assurance that either
existing or new competitors will not develop products that are superior to or
that otherwise achieve greater market acceptance than DataTRAK EDC(TM). In
addition, the Company believes that certain large players in the information
technology industry may be forming alliances and attempting to capitalize on the
data delivery options offered by the Internet. To the extent that DataTRAK's
approach to EDC may gain market acceptance, there can be no assurance that
larger players in the information technology industry will not develop competing
technology, nor as to the effect of such competing technology on DataTRAK's
operations.
 
     Regulatory Matters. On June 18, 1997, the United States Food and Drug
Administration (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
DataTRAK EDC(TM) is consistent with this draft guidance. Because the FDA's
development of this guidance is still in the early stages, no assurance can be
made that DataTRAK EDC(TM) will remain consistent with the FDA's requirements.
Any release of final FDA guidance that is significantly inconsistent with the
design of DataTRAK EDC(TM) may have a material adverse effect on the business
and operations of DataTRAK. The Company intends to continue to monitor this
guidance to ensure compliance.
 
     Potential Liability and Insurance. Clinical pharmaceutical and medical
device research requires the review and handling of large amounts of patient
data. Potential liability may arise from a breach of contract or a loss of or
unauthorized release of clinical trial data. To date, DataTRAK has not received
any claims resulting from its services. However, the Company maintains an errors
and omissions professional liability insurance policy in amounts it believes to
be sufficient to cover claims that may be brought against DataTRAK. There can be
no assurance that this coverage will be adequate, or that insurance coverage
will continue to be available to DataTRAK.
 
     Patents and Trademarks. The Company holds registered service marks
incorporating the DataTRAK process(R), and various DataTRAK trademarks,
including the DataTRAK EDC(TM) software. The DataTRAK EDC(TM) software is the
foundation of the DataTRAK process(R). The Company does not own any patents
relating to DataTRAK. Historically, the Company believed that its ability to
attract and retain highly skilled employees and manage the growth of its
business was more important to its performance than any intellectual property
rights that it has purchased or developed to date. However, upon the
consummation of the Proposed Sale, DataTRAK will become the sole component of
the Company's business, and intellectual property rights in DataTRAK will be
highly significant to the continued operation and development of the DataTRAK
business.
 
THE CLINICAL BUSINESS
 
     The Clinical Business assists Sponsors, through its network of Affiliated
Sites, in identifying and recruiting investigators, initiating clinical trials
at clinical research sites and managing clinical trials. The
 
                                       38
<PAGE>   45
 
Clinical Business also performs clinical research trials and provides other
related research services. The Clinical Business has managed trials ranging in
size from single site trials involving fewer than ten patients to a 300-site
trial involving 3,000 patients.
 
     Collaborative Clinical Research, Inc. was founded in 1991 as an Ohio
corporation. Since then, Collaborative's Clinical Business, through its
Affiliated Site Network, has assisted Sponsors in conducting the clinical
research necessary to obtain regulatory approval for new drugs and provided an
innovative strategy for developing and marketing a clinical research site
management organization. Collaborative acquired GFI and WCE in 1996. GFI
conducts Phase I clinical research at a Company-owned clinical research site.
WCE's services are directed primarily toward OTC pharmaceutical products, and
include studies necessary to switch prescription drugs to OTC use, label
comprehension evaluations and consumer product testing.
 
     The Affiliated Site Network. The Clinical Business's network of Affiliated
Sites provides a clinical research model that responds to Sponsors' needs to
bring new products to market faster. Each Affiliated Site, although not owned by
the Company, is affiliated with the Company through a written affiliation
agreement (the "Affiliation Agreement"). Under the terms of the Affiliation
Agreement the sites agree to consider clinical research business opportunities
presented to them by Collaborative. The sites have no obligation to accept any
research business, but are restricted from independently pursuing any business
opportunities presented to them by the Company. The sites also agree not to
affiliate with another network of research sites during the term of the
Affiliation Agreement and for a period of 6 to 12 months after termination of
the Affiliation Agreement. Through its network of over 450 Affiliated Sites, the
Clinical Business has the capacity to provide Sponsors with rapid access to over
3,700 principal investigators. 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 Affiliated Site Network consists of six therapeutic-focused
sub-networks that provide Phase II, III and IV clinical research services. The
Clinical Business is capable of using research sites outside of its Affiliated
Site Network if requested by the Sponsor. The Clinical Business regularly
updates its demographic database on each Affiliated Site.
 
     The Clinical Business's network approach to clinical research 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.
 
     GFI Pharmaceutical Services. GFI performs clinical research and provides
other clinical research services through its 80-bed facility located in
Evansville, Indiana for conducting Phase I through Phase IV research. 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.
 
     WCE Clinical Evaluations. WCE 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.
 
     The Clinical Business 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 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.
 
     Customers and Marketing. The Clinical Business has provided services for
many leading pharmaceutical and biotechnology companies and CROs. Its sales
personnel generally have scientific or pharmaceutical backgrounds and are
located regionally throughout the United States. The Clinical Business
concentrates a
 
                                       39
<PAGE>   46
 
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.
 
     During each of the three years in the period ended December 31, 1998, sales
to companies in the pharmaceutical industry accounted for more than 72% of the
Clinical Business's revenue. During 1996, sales to Merck & Co., Inc. and Dey
Laboratories accounted for 22% and 31% of the Clinical Business's total revenue.
Other customers in the pharmaceutical industry have from time to time accounted
for more than 10% of the Clinical Business's annual revenue. Bristol Myers
Squibb and Pharmacia & Upjohn each accounted for more than 10% of revenue during
1997. During 1998, Procter & Gamble and Hoechst Marion Roussell, Inc. each
accounted for more than 10% of revenue. The extent to which the Clinical
Business 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.
 
     Contracting and Backlog. The Clinical Business'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. All amounts received are recorded as a liability under "deferred
revenue" until work has been completed and revenue has been recognized.
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.
 
     Backlog consists of anticipated revenue from letters of intent and signed
contracts yet to be completed. 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 of December 31, 1997 and 1998, the
Company's backlog was $25.9 million and $15.8 million, respectively. Of the
$15.8 million backlog at December 31, 1998, the Company expects that $10.4
million will be converted to revenue subsequent to 1999.
 
     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 SMOs. The Clinical Business
competes in this market on the basis of its ability to provide rapid access to
high quality clinical investigators and patients through its Affiliated Sites
Network. Many of the Clinical Business's competitors have substantially greater
financial and other resources than the Clinical Business's, and there can be no
assurance of the Clinical Business's ability to continue to compete effectively
with these larger competitors. To the extent the Clinical Business'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 Clinical Business's operations. The Clinical Business may also face
competition from other networks of research sites in the recruitment of
potential Affiliated Sites.

                         SHAREHOLDERS' APPRAISAL RIGHTS
 
     Under Ohio law, all Collaborative shareholders that do not vote to approve
the Agreement have the right to dissent and seek an appraisal of the value of
their shares. In order to perfect his or her appraisal rights, a shareholder
must comply with the procedures of Section 1701.85 of the OGCL, outlined briefly
as follows:
 
     (1) No vote may be cast in favor of the proposal;
 
     (2) Written demand for payment of the fair cash value of the shares owned
         must be sent to the Company within ten days after the vote on the
         proposal was taken; and
 
     (3) If the Company does not agree on a fair cash value with the
         shareholder, then the shareholder must file a complaint with the
         Cuyahoga County Court of Common Pleas, State of Ohio, seeking a
         judicial determination of the fair cash value of the shares owned.
 
Any Collaborative shareholder contemplating the exercise of appraisal rights is
urged to carefully review the description of these procedures contained in this
section of the Proxy Statement. Shareholders will lose their appraisal rights if
they do not strictly comply with the required procedures. The following
description of these procedures is qualified in its entirety by reference to
Section 1701.85 of the OGCL, a copy of which is attached as Appendix C of this
Proxy Statement.
 
     No Vote in Favor of the Agreement. A Collaborative shareholder that wishes
to exercise appraisal rights may not vote to approve the Agreement. A vote in
favor of the Agreement constitutes a waiver of appraisal rights. The following
examples satisfy this requirement:
 
     (1) The enclosed proxy card is signed and returned with instructions to
         vote against the Agreement;
 
     (2) The enclosed proxy card is signed and returned with instructions to
         abstain from a vote on the Agreement;
 
     (3) The enclosed proxy is not returned and no vote is cast in person at the
         Meeting in favor of the Agreement; or
 
     (4) The shareholder revokes a proxy in favor of the Agreement and later
         abstains from voting on the Agreement or votes against the Agreement in
         person at the Meeting.
 
If the enclosed proxy card is returned with a signature but without an
indication of voting preference, the shares represented by that card will be
voted in favor of the Agreement and will constitute a waiver of appraisal
rights.
 
     A shareholder may revoke his or her proxy at any time before its exercise
by filing with the Company an instrument revoking it or a duly executed proxy
bearing a later date, or by attending and giving notice of the revocation of the
proxy at the Meeting. However, attendance at the Meeting will not in and of
itself constitute revocation of a proxy. See "The Meeting -- Proxies: Voting and
Revocation."
 
     Delivery of Written Demand. Within ten days after the Agreement is voted
on, a dissenting shareholder must send to the Company a written demand for
payment of the fair cash value of that shareholder's dissenting shares. Voting
against the Agreement will not itself qualify as a written demand, and the
Company will not notify shareholders of the expiration of the ten-day period.
 
     The written demand must identify the name and address of the holder of
record of the dissenting shares, the number of dissenting shares and the amount
claimed as the fair cash value of those shares. The written demand must be
signed by the shareholder of record (or by a duly authorized representative of
the shareholder) exactly as the shareholder's name appears on the shareholder
records of the Company. If dissenting shares are jointly owned by more than one
person, the written demand must identify and be signed by all of the
shareholders of record. Any person signing a written demand on behalf of a
partnership or corporation, or in any other representative capacity (such as
attorney-in-fact, executor, administrator, trustee, or guardian), must state the
nature of the representative capacity and, if requested, must furnish written
proof of this capacity and such person's authority to sign the demand.
 
                                       41
<PAGE>   48
 
     If shares are held of record in a brokerage account or by a fiduciary,
custodian, nominee or other holder and the shareholder wishes to exercise
dissenters' rights, he or she must instruct the record holder of the shares to
satisfy the conditions outlined above. If the record holder does not satisfy all
of the conditions outlined in this section within ten days, the shareholder will
lose his or her dissenter's rights.
 
     The fair cash value of the shares is an amount that a seller, under no
compulsion to sell, would accept, and that a buyer, under no compulsion to
purchase, would pay. The fair cash value should be determined as of the date
before the day of the vote on the Agreement. When calculating this amount,
appreciation or depreciation in the market value of the dissenting shares as a
result of the Agreement and the Proposed Sale is excluded.
 
     A dissenter's written demand should be delivered to the Company at 20600
Chagrin Boulevard, Cleveland, Ohio 44122, Attention: Secretary. It is
recommended, although not required, that the written demand be sent by
registered or certified mail, return receipt requested.
 
     After the written demand is sent, all rights normally accruing to the
shareholder are suspended until the shareholder's appraisal rights are satisfied
or the Company purchases the dissenting shares. Consequently, upon delivery of
the written demand, a dissenting shareholder may not vote his or her shares and
is no longer entitled to dividends or distributions. If any cash dividend or
distribution is paid on the Company's Common Shares during this suspension
period, the value of the dividend or distribution which would have been paid,
but for such suspension, will be paid to the record shareholder of the
dissenting shares as a credit upon the fair cash value thereof. If the
dissenter's right to receive a fair cash value is terminated otherwise than by
the purchase of the dissenting shares by Company, all rights will be restored to
the dissenting shareholder and any distribution that would have been made to him
or her, but for the suspension, will be made at the time of the termination.
 
     Complaint to be Filed in Court. If the Company and the dissenting
shareholder do not agree on the fair cash value of the dissenting shares within
three months after the written demand was sent, the dissenting shareholder or
the Company may file a complaint in the Cuyahoga County Court of Common Pleas,
State of Ohio, or join or be joined in an action similarly brought by another
dissenting shareholder, for a judicial determination of the fair cash value of
the dissenting shares. The Company does not intend to file any complaint for a
judicial determination of the fair cash value of any dissenting shares.
 
     If the court concludes that the dissenting shareholder is entitled to
payment of the fair cash value of his or her shares, it may appoint one or more
appraisers to recommend a decision on the dollar amount of the fair cash value.
After determining the fair cash value of the dissenting shares, the court would
render a judgment requiring the Company to pay the fair cash value plus any
accrued interest determined at a rate and from a date considered equitable by
the court. The court will also apportion or assess the costs of the proceedings,
including reasonable appraisers' fees.
 
     If the Agreement is terminated or the Proposed Sale is not consummated, all
rights of dissent and appraisal that have been perfected will be terminated.

              PROPOSAL TO APPROVE AN AMENDMENT TO THE ARTICLES OF
                INCORPORATION TO CHANGE THE NAME OF THE COMPANY
 
     The text of Article I of the Company's Fifth Amended and Restated Articles
of Incorporation, constituting the provision establishing the name of the
Company, as proposed to be amended, is included in the Form of Certificate of
Amendment to the Company's Fifth Amended and Restated Articles of Incorporation
(the "Certificate of Amendment") attached as Appendix D to this Proxy Statement.
The following discussion of the Certificate of Amendment is qualified in its
entirety by reference to the text of the Certificate of Amendment.
 
     At a special meeting held February 10, 1999, the Collaborative Board of
Directors adopted a resolution approving a proposed amendment to Article I of
the Company's Fifth Amended and Restated Articles of Incorporation to change the
name of the Company to DataTRAK International, Inc. Approval of the Certificate
of Amendment is required as a condition to the Proposed Sale because the
Agreement contemplates that West will purchase, among other things, the name
"Collaborative Clinical Research." The Board has concluded that approval of the
Certificate of Amendment would also be in the best interests of the Company's
shareholders because the name DataTRAK International, Inc. will more accurately
communicate the Company's business after the consummation of the Proposed Sale.
 
     THE APPROVAL AND ADOPTION OF THE CERTIFICATE OF AMENDMENT CHANGING THE
COMPANY'S NAME IS CONDITIONED UPON THE APPROVAL OF THE AGREEMENT AND THE CLOSING
OF THE PROPOSED SALE.
 
CERTAIN EFFECTS OF THE PROPOSED AMENDMENT
 
     The proposed name change will not affect the Company's operations or
business, or the rights of shareholders of the Company. As soon as practicable
following the effectiveness of the Certificate of Amendment, the Company will
cause transmittal letters to be mailed to shareholders for use in forwarding
their certificates for Common Shares for surrender and exchange for new
certificates reflecting the change in the Company's name.
 
RECOMMENDATION; REQUIRED VOTE
 
     THE COLLABORATIVE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE CERTIFICATE OF AMENDMENT. THE
AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING COMMON SHARES
OF THE COMPANY IS REQUIRED TO APPROVE AND ADOPT THE CERTIFICATE OF AMENDMENT.

               PROPOSAL TO APPROVE AN AMENDMENT TO THE COMPANY'S
                       AMENDED AND RESTATED 1996 OUTSIDE
                          DIRECTORS STOCK OPTION PLAN
 
     Shareholders will be asked at the Meeting to vote on a proposal to approve
an amendment (the "Amendment") to the Company's Amended and Restated 1996
Outside Directors Stock Option Plan, as amended (the "Plan"), to increase the
number of Common Shares available under the Plan and amend the formula for
automatic awards of options under the Plan. The text of the proposed amendment
is included in the Form of Amendment No. 2 to the Plan (the "Amendment")
attached as Appendix E to this Proxy Statement. The following discussion of the
Amendment is qualified in its entirety by reference to the text of the
Amendment.
 
     The following discussion describes the Plan as it is proposed to be
amended. Where there are material differences between the Plan as it is proposed
to be amended and the Plan as it currently exists, such differences will be
noted by a comparison of the Amendment and the "Current Plan," respectively.
 
GENERAL PLAN INFORMATION
 
     The Plan was adopted by the Company's Board of Directors on February 29,
1996 and approved by the Company's shareholders on May 2, 1996. The Plan was
subsequently amended on September 20, 1996 and May 20, 1997. As of the date of
this Proxy Statement, there were 27,500 Common Shares available for future grant
under the Plan.
 
     The effective date of the Plan was February 29, 1996. By its terms, the
Plan will terminate on February 29, 2006; however, the Plan's expiration will
not affect any outstanding option.
 
     The purpose of the Plan is to provide those Directors of the Company who
are not employees of the Company or any of its subsidiaries or affiliates
("Outside Directors") with a greater incentive to serve and promote the
Company's success by encouraging them to acquire new or additional share
ownership in the Company, thus increasing their proprietary interest in the
Company's business and providing them with an increased personal interest in the
Company's continued success and development. Currently, the Company operates a
small, growth-oriented business. As such, stock option awards and stock-based
compensation play an integral role in providing compensation to the Company's
current Outside Directors and attracting future Outside Directors. Therefore,
the Compensation Committee and the Board of Directors approved the authorization
of an amendment increasing the number of Common Shares available for issuance
under the Plan to 175,000 and amending the manner in which automatic awards of
options will be effected under the Plan in order to further the purposes of the
Plan through the foreseeable future and to continue to have access to a
sufficient pool of Common Shares to be covered by stock options.
 
     The Company believes that the Plan is not subject to the provisions of the
Employee Retirement Income Security Act of 1974, as amended. The Plan is not
qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended.
 
THE AMENDMENT
 
     The Current Plan provides for annual, automatic awards to Outside Directors
of non-qualified stock options to purchase 1,500 Common Shares of the Company.
The Current Plan also provides for awards of stock options to purchase an
aggregate of 50,000 Common Shares.
 
     Under the terms of the Amendment and subject to shareholder approval of the
Amendment, each person who was an Outside Director on July 23, 1998 received a
non-qualified stock option to purchase 10,000 Common Shares at an exercise price
of $4.19 per share (the fair market value of a share on the date of grant). In
addition, the Amendment provides for each Outside Director to receive a
non-qualified stock option to purchase 10,000 Common Shares upon their initial
appointment or election, or re-election, as Outside Directors. The Amendment
also provides for the automatic annual award to Outside Directors on the day
following the Company's annual meeting of shareholders of non-qualified stock
options to purchase
 
                                       44
<PAGE>   51
 
2,500 Common Shares. The Amendment also provides for an increase in the number
of Common Shares available for awards of stock options under the Plan from
50,000 to 175,000.
 
     The information below provides, in tabular format, the number of
non-qualified stock options that will be received by or are allocated to Outside
Directors. Non-qualified stock options awarded under the Plan may not be awarded
to persons other than Outside Directors. The dollar value of such non-qualified
stock options is not determinable.

ADMINISTRATION
 
     The Plan does not provide the Board of Directors, any committee thereof, or
any other person, with discretionary authority with respect to its
administration. Eligibility criteria for awards of options, as well as the
timing, amount, price, vesting, term and other terms of option awards, are set
forth in the Plan itself.
 
SECURITIES TO BE OFFERED
 
     Under the terms of the Amendment, up to an aggregate of 175,000 of the
Company's Common Shares are available for awards of options to the Company's
Outside Directors. Under the terms of the Current Plan, up to an aggregate of
50,000 of the Company's Common Shares are available for awards of options to the
Company's Outside Directors.
 
     Either treasury or authorized and unissued shares, or both, in such amount
or amounts, within the maximum limits of the Plan, as the Board of Directors
shall from time to time determine, may be so issued. If an option awarded under
the Plan is exercised pursuant to the terms and conditions of the Plan, any
Common Shares that are the subject thereof shall not thereafter be available for
re-offering under the Plan.
 
     In the event that, subsequent to the date of adoption of the Plan by the
Board of Directors, the outstanding Common Shares of the Company should be
increased or decreased or changed into or exchanged for a different number or
kind of shares or other securities of the Company, as a result of a share split,
share dividend, combination or exchange of shares, exchange for other
securities, reclassification, reorganization, redesignation, merger,
consolidation, recapitalization or other such change, then (i) there shall
automatically be substituted for each share subject to an unexercised option (in
whole or in part) granted under the Plan, each share available for additional
grants of options under the Plan and each share made available for grant to each
Outside Director pursuant to Section 4 of the Plan, the number and kind of
shares or other securities into which each outstanding share shall be changed or
for which each such share shall be exchanged, (ii) the option price per share or
unit of securities shall be increased or decreased proportionately so that the
aggregate purchase price for the securities subject to the option shall remain
the same as immediately prior to such event and (iii) the Board of Directors
shall make such other adjustments as may be appropriate and equitable to prevent
enlargement or dilution of option rights. Any such adjustment may provide for
the elimination of fractional shares.
 
OPTION PROVISIONS
 
     Automatic Awards. The Amendment provides that each Outside Director will be
awarded non-qualified stock options to purchase such number of the Company's
Common Shares as follows:
 
     (1) Each Director who was an Outside Director on July 23, 1998 shall
         receive a non-qualified stock option to purchase 10,000 Common Shares
         at an exercise price equal to the "fair market value" (defined below)
         of such shares on July 23, 1998;
 
                                       45
<PAGE>   52
 
     (2) Each Director newly appointed or elected, or re-elected, as an Outside
         Director after July 23, 1998 shall thereupon receive a non-qualified
         stock option to purchase 10,000 Common Shares at an exercise price
         equal to the fair market value of such shares as of the date of the
         award;
 
     (3) Each Director who is an Outside Director on the first day following the
         Company's annual meeting of shareholders commencing with the meeting to
         be held in 1999, shall receive a non-qualified stock option to purchase
         2,500 Common Shares at an exercise price equal to the fair market value
         of such shares as of the date of the award.
 
     The Current Plan provides that each Outside Director will automatically
receive a non-qualified stock option for 1,500 Common Shares as of the date of
the Plan's approval by the Company's Board of Directors and will receive a
non-qualified stock option for 1,500 on each anniversary date thereof. Each
Outside Director first appointed or elected to the Company's Board of Directors
after the effective date of the Plan shall be granted a non-qualified share
option to purchase 1,500 Common Shares as of the date of such appointment or
election in addition to a non-qualified share option for 1,500 on each
anniversary date thereof.
 
     The Plan provides that such grants shall occur automatically without any
further action by the Board of Directors.
 
     Option Price. The option price per Common Share under each option granted
pursuant to the Plan shall be equal to the fair market value thereof, but in no
event shall such price be less than the par value of such Common Shares.
 
     Period of Option. Each option granted under the Plan shall expire and all
rights to purchase Common Shares pursuant thereto shall cease on the tenth
anniversary of the date of grant.
 
     Vesting of Options. The Amendment provides that each Outside Director shall
be entitled to exercise options granted under the Plan as follows:
 
     (1) With respect to non-qualified stock options to purchase 10,000 Common
         Shares awarded on July 23, 1998 or upon a Director's initial
         appointment or election, or re-election, as an Outside Director, each
         such option shall become fully vested and exercisable as to 3,333 of
         the underlying Common Shares on the day following the first anniversary
         of the date on which the option was awarded, 6,666 of the underlying
         Common Shares on the day following the second anniversary of the date
         on which the option was awarded and 10,000 of the underlying Common
         Shares on the third anniversary of the day on which the option was
         awarded; and
 
     (2) With respect to non-qualified stock options to purchase 2,500 Common
         Shares awarded on the day following the date of the Company's annual
         meetings of shareholders, each such option shall become fully vested
         and exercisable as to all of the underlying Common Shares on the day
         following the first anniversary of the date on which the option was
         awarded.
 
     The Current Plan provides that each option awarded under the Plan shall
become fully vested and exercisable six months following the date on which the
option was awarded. For purposes of the Plan (and the Company's other stock
option plans), the closing of the Proposed Sale will qualify as change in
control. Pursuant to the terms of the Plan (and the Company's other stock option
plans), all options outstanding upon the occurrence of a change in control,
including the closing of the Proposed Sale, will become immediately vested and
exercisable (including the options to purchase 10,000 Common Shares awarded to
each Outside Director on July 23, 1998).
 
     Limitations on Exercise and Transfer of Options. All or any portion of an
option shall be transferable by the optionee, in whole at any time or in part
from time to time, to (i) any member of the optionee's immediate family, (ii)
any trust whose beneficiaries consist solely of the optionee and/or members of
the optionee's immediate family and (iii) any person or entity who is an
"affiliate" of the optionee (as such term is defined in Rule 501(b) of
Regulation D promulgated under the Securities Act). Notwithstanding the
foregoing, the Company shall be under no obligation to record any such transfer
upon the books of the Company and may treat the optionee as the record and
beneficial owner thereof for all purposes until such time as: (a) the transferor
delivers to the Company a fully executed assignment of option, (b) the
transferee delivers to the
 
                                       46
<PAGE>   53
 
Company a fully executed joinder to the option agreement and (c) the transferor
and transferee establish, to the reasonable satisfaction of the Company, that
such a transfer is permitted under applicable provisions of the federal
securities laws. No option may be pledged or hypothecated, nor may any option be
subject to execution, attachment or similar process.
 
     Conditions Governing Exercise of Option. Options are exercisable by the
Outside Director by giving written notice to the Company, of the Outside
Director's intention to exercise the option and the number of Common Shares with
respect to which the option is being exercised, accompanied by full payment of
the purchase price either in cash or in whole or in part in Common Shares having
a fair market value on the date the option is exercised equal to that portion of
the purchase price for which payment in cash is not made.
 
     Termination of Directorship. Subject to the following provisions, if the
Outside Director ceases to be a Director of the Company, his or her option shall
terminate three (3) months after the effective date of termination of his or her
directorship and neither he nor she nor any other person shall have any right
after such date to exercise all or any part of such option. If the termination
of the directorship is due to death, then the option may be exercised within one
year after the Outside Director's death by the Outside Director's estate or by
the person designated in the Outside Director's last will and testament or to
whom transferred by the applicable laws of descent and distribution.
Notwithstanding the foregoing, in no event shall any option be exercisable after
the expiration of the ten-year option period and no option shall be exercisable
to any greater extent than the Outside Director would have been entitled to
exercise the option at the time of termination or death.
 
INCOME TAX TREATMENT
 
     An Outside Director will not realize income upon the granting of a
non-qualified option; however, in any year in which an Outside Director
exercises a part or all of such option, the excess, if any, of the fair market
value of the Common Shares at the date of exercise over the option price will be
taxed as compensation at ordinary income tax rates, and the Company will be
entitled to a tax deduction for a like amount in the same year. An Outside
Director may elect, within 30 days after the issuance of Common Shares upon the
exercise of an option (which the Internal Revenue Service may assert occurs on
the date of exercise), to treat the excess, if any, of the fair market value of
the Common Shares on the date of issuance over the option price as ordinary
income at that time, and the Company will be entitled to a tax deduction for a
like amount. If this election is made, no additional income will be realized by
the Outside Director on the date six months after the date of issuance.
 
     The Company has made provisions for all taxes required in connection with
an option exercise to be withheld and/or paid. The Company has the discretion to
allow the Outside Director to satisfy tax withholding requirement by (a) the
Company withholding from issuance to the Outside Director the number of Common
Shares agreed upon by the Company and the Outside Director, so long as the
Outside Director has executed an effective standing election to satisfy such tax
withholding requirements within at least six months prior to an option exercise;
or (b) withholding the number of Common Shares equal to that portion of the
withholding obligation for which cash payment has not been made, provided that
consent has been given by the Company's Board of Directors.
 
     As of the date of this Proxy Statement, options to purchase an aggregate of
92,500 Common Shares (including the options to purchase 70,000 shares that were
awarded July 23, 1998, subject to shareholder approval) were awarded to Outside
Directors at a weighted average exercise price of $4.82 per share.
 
     Except for stock options granted under the Plan, the Company does not
intend to compensate Directors for any meetings that they attend, but will
reimburse them for reasonable expenses that are incurred in attending such
meetings.
 
RECOMMENDATION; REQUIRED VOTE
 
     THE COLLABORATIVE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE AMENDMENT. THE AFFIRMATIVE
VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING COMMON SHARES OF THE
COMPANY ENTITLED TO VOTE AND PRESENT AT THE SPECIAL MEETING, IN PERSON OR BY
PROXY, IS REQUIRED TO APPROVE AND ADOPT THE AMENDMENT.

<PAGE>   54
 
                           COMPENSATION OF DIRECTORS
 
     Directors do not receive cash compensation for their service on the
Company's Board. However, they do receive reimbursement for reasonable expenses
incurred in attending Board meetings. Directors who are not also employees
receive options to purchase Common Shares under the Company's Amended and
Restated 1996 Outside Directors' Stock Option Plan, as amended. Under the terms
of this plan, each non-employee Director receives an annual option grant to
purchase 1,500 Common Shares at an exercise price equal to the fair market value
of a share on the date of grant. As of the date of this Proxy Statement, options
to purchase an aggregate of 92,500 Common Shares (including the options to
purchase 70,000 shares that were awarded July 23, 1998, subject to shareholder
approval) have been awarded and were outstanding under this plan at a weighted
average exercise price of $4.82 per share. Options awarded under this plan vest
six months after the date of grant and expire ten years from the date of grant.
Prior to the Company's initial public offering in June 1996, Directors received
options under other option plans maintained by the Company, as described below.
 
     Non-employee Directors received options to purchase Common Shares under the
Company's Amended and Restated 1992 Share Incentive Plan (the "1992 Plan").
Options to purchase an aggregate of 80,000 Common Shares were awarded to
non-employee Directors under the 1992 Plan at an exercise price of $0.15 per
share. Each Director who is not an executive officer named in the Executive
Compensation tables below received options to purchase the following numbers of
shares under the 1992 Plan: Mr. Harris, 25,000 shares; Dr. Stote, 25,000 shares;
and Dr. Ratain, 30,000 shares. Dr. Ratain was awarded stock options for his
service as a consultant to the Company prior to his current service on the
Company's Board. In addition, prior to the Company's initial public offering in
June 1996, members of the Board who were designated to serve as such by certain
of the Company's private investors received, in lieu of Directors' fees, options
to purchase Common Shares having a value equal to $1,000 for each meeting
attended ($500 for each meeting attended by telephone). These awards were made
under the Company's Amended and Restated 1994 Directors' Share Option Plan (the
"1994 Plan"). An aggregate of 6,833 Common Shares were awarded and are
outstanding under the 1994 Plan at a weighted average exercise price of $4.54
per share.

under this agreement, Mr. Folz is entitled to terminate his employment for "good
reason." "Good reason" for such termination will exist if at any time, except in
strict compliance with the terms of the agreement, (i) Mr. Folz's duties,
responsibilities or title are materially reduced, (ii) Mr. Folz's base salary is
reduced or (iii) Mr. Folz is required by the Company to relocate his business
offices to a new city. If Mr. Folz terminates his employment with the Company
for good reason, he will be entitled to receive his base salary for a period of
one year following the date of such termination. If Mr. Folz's employment with
the Company is terminated in connection with the sale of the Company, he will be
entitled to continue to receive his base salary for one year following the date
of such termination. If his employment is terminated without cause, he will be
entitled to receive his base salary for a period of one year subsequent to the
date of termination. If Mr. Folz terminates his employment with the Company
without good reason, or if he is terminated by the Company for "cause," he will
be entitled to receive his base salary through the date of termination. For

purposes of Mr. Folz's agreement, "cause" is defined as (i) failure to complete
satisfactorily the Company's routine pre-employment background check, (ii)
conviction of a felony involving moral turpitude or a felony in connection with
his employment, (iii) fraud, (iv) use or possession of illegal drugs on the
Company's premises or reporting to work under the influence of same, or (v)
engaging in conduct, in or out of the workplace, which may be reasonably
determined to have an adverse effect on the reputation or business of the
Company. Mr. Folz also agreed to certain noncompetition and nondisclosure
provisions which continue for a period of one year following a termination of
Mr. Folz's employment with the Company.
 
     Philip A. Stark. In 1997, the Company entered into an employment agreement
with Mr. Stark providing for an initial term of four years, and thereafter
automatically renewed for successive one-year terms unless otherwise terminated
in accordance with the agreement. The base salary provided for in this agreement
for the first year of employment was $116,000, with the base salary increasing
to $132,000 for each year thereafter. On the first anniversary of the agreement,
Mr. Stark was entitled to a bonus of $16,000. The agreement also provided Mr.
Stark with the right to participate in all benefits plans made available to the
Company's executives and/or employees. Mr. Stark's employment with the Company
could have been terminated with or without cause, upon his death or disability
or with "sufficient reason." Additionally, under his agreement, Mr. Stark was
entitled to terminate his employment for "good reason." "Good reason" for such
termination would have existed if at any time the Company committed a material
breach of the agreement, failed to employ Mr. Stark as a management executive or
failed to vest Mr. Stark with the powers and authority customarily associated
with executives of the Company. If Mr. Stark had terminated his employment with
the Company for good reason, he would have been entitled to continue to receive
his base salary for a period of one year following the date of such termination.
If Mr. Stark's employment had been terminated in connection with the sale of the
Company, he would have been entitled to receive a payment equal to three times
his then current base salary, and all of his previously unvested stock options
would become vested prior to such sale. If Mr. Stark's employment had been
terminated without cause or sufficient reason, he would have been entitled to
receive his base salary for a period of two years following the date of such
termination, and all of his unvested options would have become fully vested. If
Mr. Stark had terminated his employment without good reason, or if he had been
terminated by the Company with sufficient reason or for "cause," he would have
been entitled to receive his base salary through the date of termination. For
purposes of Mr. Stark's agreement, "cause" was defined as a determination that
the employee engaged in (i) fraud, (ii) breach of the material provisions of the
agreement or (iii) a willful failure to perform his duties as required under the
agreement. "Sufficient reason" was defined as a good faith determination that
the employee failed to (i) adequately perform his duties as an officer of the
Company or (ii) exercise a level of judgment and skill in the management of the
Company comparable to other similarly situated executives, following 60 days
notice from the Chief Executive Officer of dissatisfaction with the employee's
performance or (iii) achieve the business objectives mutually agreed upon by the
parties. Mr. Stark also agreed to certain non-competition provisions which
continue for a period of two years following the termination of his employment
with the Company.
 
     In connection with the Company's 1998 corporate reorganization, Mr. Stark's
employment with the Company was terminated on May 4, 1998. Pursuant to Mr.
Stark's employment agreement, Mr. Stark was entitled to receive $255,342 upon
his termination. In 1998, $126,402 of the $255,342 was paid to Mr. Stark and the
remainder will be paid to him in 1999.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
GENERAL
 
     The Compensation Committee administers the Company's stock option plans,
including the selection of optionees and the timing of option grants, and
reviews and monitors key employee compensation and benefits policies and
administers the Company's management compensation plans. The current members of
the Compensation Committee are Messrs. Flaherty and Harris and Dr. Stote, all of
whom are non-employee Directors.
 
     Set forth below is a discussion of the Company's compensation philosophy,
together with a discussion of the factors considered by the Committee in
determining the compensation of the Company's President and Chief Executive
Officer and the executive officers named in the Executive Compensation tables
above.
 
COMPENSATION PHILOSOPHY
 
     The Company's compensation philosophy is that compensation paid to
executive officers and other management personnel should consist of four
elements: (1) salary, (2) annual incentive bonus, (3) stock options and (4)
welfare, retirement and other benefits. The compensation package is designed to
attract and retain top quality management employees. In the opinion of the
Committee, it reflects competitive conditions of peer group companies. To some
extent, elements of compensation are designed to vary as Company performance
varies. In general, the elements of compensation that most typically have a
significant relationship to Company performance are awards under its stock
option and bonus plans. The Committee's decisions concerning compensation make
use of independent surveys of executive compensation of similarly situated
companies.
 
     The Company has entered into employment agreements with all of its
executive officers. In general, the Committee believes that employment
agreements are a useful tool in attracting and retaining qualified executives.
 
     Set forth below is a discussion of the various components of the
compensation arrangements provided to the executive officers, as well as a
discussion of the compensation arrangements provided to the Company's President
and Chief Executive Officer.
 
1998 COMPENSATION DECISIONS
 
     Base Salary and Benefits. Salaries of executive officers are subject to
minimum levels set by the terms of each executive's employment arrangement with
the Company. The primary factor in setting salary levels pursuant to these
arrangements was the Company's desire to provide compensation in amounts
sufficient to induce these individuals to either join or continue with the
Company. Salary levels for executive officers reflect the Committee's judgments
on appropriate salaries in light of the duties and responsibilities inherent in
the executives' respective positions. The particular qualifications of an
individual holding the position and his or her level of experience, as well as
information concerning compensation paid by other companies in the industry, are
considered in establishing salary levels. The Committee's assessment of the
individual's performance and contribution to the Company's performance are the
primary criteria influencing decisions regarding salary. For those executives
who joined the Company during the year, the primary factor in setting salary
levels was the Company's desire to provide compensation in amounts sufficient to
induce these individuals to join the Company.
 
     Stock Options. The Company uses stock options as a long-term incentive
program for executive officers. Stock options are used because they directly
relate the amounts earned by the executive officers to the amount of
appreciation realized by the Company's shareholders over comparable periods.
Stock options also provide executive officers with the opportunity to acquire
and build a meaningful ownership interest in the Company. The Committee
considers stock option awards throughout the year. In determining the number of
options awarded to an individual executive officer, the Committee generally
establishes a level of award based upon the position of the individual and his
or her level of responsibility and upon recommendations made by the Company's
President and Chief Executive Officer. The Committee's decisions concerning
individual option awards are based on its judgment concerning the appropriate
amount of long-term compensation that should
 
                                       54
<PAGE>   61
 
be paid to the executive in question. The Company did not award any such stock
options during the 1998 fiscal year.
 
     Bonuses. Pursuant to the terms of its employment agreements with the
executive officers of the Company, the Company may pay additional compensation
in the form of discretionary bonuses. In general, the bonus structure is
open-ended and the bonus amount in any given year is determined by the
Committee. Bonuses may be provided either in the form of cash, Common shares or
a combination of the two, as the Committee determines. The Company did not pay
bonuses to its executive officers with respect to performance during the 1998
fiscal year. However, in 1999, the Compensation Committee has determined that,
upon consummation of the Proposed Sale pursuant to the terms described in the
Agreement, Mr. Hugill will be paid a cash bonus of $20,000.
 
PRESIDENT AND CHIEF EXECUTIVE OFFICER COMPENSATION
 
     Dr. Green's employment contract with the Company contemplates compensation
in two broad areas: (i) a base salary and (ii) stock options under a long-term
compensation plan. His employment agreement provided for a base salary of
$180,000 for 1997 and 1998. When the Company failed to meet certain objectives
with regard to financial performance during 1997, Dr. Green elected to defer a
portion of his 1997 salary. As a result, Dr. Green was paid $160,984 in salary
for 1997. Dr. Green was paid his full salary of $180,000 in 1998.
 
     In November 1996, the Compensation Committee evaluated Dr. Green's role in
managing and finalizing the Company's initial public offering of Common Shares
in 1996. The Committee also evaluated his role in bringing about the Company's
most financially successful year since its formation. In January 1997, based on
this evaluation, Dr. Green was awarded options to purchase 25,000 Common Shares
at an exercise price of $10.75 per share. These options vest over four years,
and expire in ten years.
 
                                          THE COMPENSATION COMMITTEE
 
                                          Robert E. Flaherty
                                          Seth B. Harris
                                          Dr. Robert M. Stote
 
          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Company has engaged in various private transactions with the members of
its Compensation Committee or entities with which they are affiliated. The
Company believes that these transactions have been on terms no less favorable to
the Company than could have been obtained from unaffiliated third parties.
 
     The Company engaged in various private equity financing transactions with
Mr. Harris, Dr. Stote and other shareholders in 1992, 1993 and 1994. Since these
arrangements were the result of arm's length negotiation among the Company and
these shareholders prior to their acquisition of an interest in the Company, the
Company believes that the arrangements are on terms no less favorable to it than
could have been obtained from unaffiliated third parties. As a result of various
financing transactions, the Company is a party to a registration rights
agreement with Dr. Stote and Mr. Harris. Under the terms of this agreement, the
holders of an aggregate of 1,990,332 Common Shares (the "Registrable Shares")
have the right to demand, no more than once every six months, registration under
the Securities Act of 1933, as amended, of the Common Shares having a market
value of at least $5,000,000 (in the case of a registration on Form S-1) or
$1,000,000 (in the case of a registration on Form S-2 or S-3). Such demand right
may be exercised by the holders of at least 40% of the Registrable Shares. The
holders of Registrable Shares may exercise their right to demand registration of
the Registrable Shares on Form S-1 up to two times at the Company's expense, and
any demand registrations on Form S-2 or S-3 an unlimited number of times at the
Company's expense. Although the holders of Registrable Shares have the right to
demand additional registrations on Form S-1, they will be required to pay their
share of the expenses associated with such registrations. The agreement also
provides the holders of an aggregate of 497,116 Common Shares (the "Related
Shares") with the limited right to participate, at their own expense, in a
registration statement demanded by the holders of Registrable Shares. In
addition, under certain conditions, the holders of Registrable Shares and
Related Shares have the
 
                                       55
<PAGE>   62
 
limited right to include some or all of such shares in any registration
statement filed by the Company with respect to the sale of Common Shares.
 
                               PERFORMANCE CHART
 
     The following line graph compares the percentage change in the cumulative
total shareholder return on the Company's Common Shares against the cumulative
total return of The Nasdaq Stock Market -- U.S. Index and the Nasdaq Health
Services Index for the period commencing June 11, 1996 (the initial trading date
for the Common Shares) and ending December 31, 1998. The graph assumes that the
value of the investment in Common Shares and each index was $100 on June 11,
1996, and that all dividends, if any, were reinvested.

discretion of the Company's Board of Directors after taking into account various
factors, including the Company's financial condition, results of operations and
current and anticipated cash needs.

                         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, 1997
and 1998, and the related consolidated statements of operations, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1998. 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, 1997 and
1998, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998
 
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.
 
  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 $126,600 and $53,100 at December 31, 1997
and 1998, 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 other
political subdivisions, and U.S. corporate obligations 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. Depreciation
expense was $320,000, $590,000 and $820,000 for 1996, 1997 and 1998,
respectively.
 
  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.
 
  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.
 
  Impairment of Long-Lived Assets
 
     The Company evaluates impairment of long-lived assets in accordance with
SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of" ("SFAS 121"). As such the carrying values
of long-lived assets are evaluated if circumstances indicate a possible
impairment in value. If undiscounted cash flows over the remaining amortization
period indicate that long-lived assets may not be recoverable, the carrying
value will be reduced by the estimated shortfall of cash flows on a discounted
basis. (See note 2).

  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 $170,000,
$300,000 and $340,000 for 1996, 1997 and 1998, respectively.
 
  Software Development Costs
 
     Development costs incurred in the research and development of new software
products and enhancements to existing software products are expensed as incurred
until technological feasibility has been established. After technological
feasibility is established, any additional costs are capitalized in accordance
with Statement of Financial Accounting Standards No. 86. "Accounting for the
Costs of Computer Software to be Sold, Leased, or Otherwise Marketed." Such
costs are amortized over the lesser of three years or the economic life of the
related product. The Company performs an annual review of the recoverability of
such capitalized software costs. At the time determination is made that
capitalized amounts are not recoverable based on the estimated cash flows to be
generated from the applicable software, any remaining capitalized amounts are
written off.
 
     Unamortized software and software development costs included in the
Company's balance sheet were zero and $780,000 at December 31, 1997 and 1998,
respectively. Amortization expense related to capitalized software costs was
zero in 1996 and 1997, and $280,000 in 1998.
 
  Foreign Currency Translation
 
     The assets and liabilities of the Company's foreign subsidiaries are
translated into U.S. dollars at current exchange rates. Revenue and expense
accounts of these operations are translated at average rates prevailing during
the period. These translation adjustments are accumulated in a separate
component of shareholders' equity. Foreign currency transaction gains and losses
are included in determining net income (loss) when realized.
 
  Recently Issued Accounting Standards
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" ("Statement No. 130"), which is effective
for years beginning after December 15, 1997. SFAS 130 establishes standards for
reporting and displaying comprehensive income and its components in financial
statements. The Company adopted Statement No. 130 effective January 1, 1998.
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
131, "Disclosures about Segments of an Enterprise and Related Information"
("Statement No. 131"), which is effective for years beginning after December 15,
1997. Statement No. 131 establishes standards for the way that public business
enterprises report information about operating segments in annual financial
statements and requires that those enterprises report selected information about
operating segments in interim financial reports. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. The Company has reported information for two segments (Clinical
Business and DataTRAK, Inc.).

2.  IMPAIRMENT CHARGES AND SPECIAL ITEMS
 
     Results of operations for 1997 included special items charges of $2,994,597
related to costs associated with exiting certain Company activities. Of this
total, $2,000,000 represented the Company's best estimate of its costs
associated with the termination of its technology alliance with IBM. Also, as a
result of the termination of the technology alliance, $737, 916 of unamortized
software was written off. The remaining $256,681 was for the
disposal/abandonment of certain medical and computer equipment and the closing
of a leased facility, which occurred during the fourth quarter of 1997.
 
     During 1998, the Company recorded total special items charges of
$1,998,187. The Company recorded a charge of $1,439,762 in the first quarter of
1998 to recognize costs associated with employee severance and other special
items including the March 24, 1998 termination of 29 employees pursuant to a
reorganization plan announced in March 1998 and expected to be completed before
the end of the second quarter of 1998. In June 1998, an additional special items
charge of $271,425 was recorded related to the closing of the Company's United
Kingdom operations (including the termination of two employees) and the
termination of a joint venture in the United Kingdom, and additional costs
incurred in connection with the termination of the IBM and DataTRAK alliance. In
September 1998, a special items charge of $287,000 was recorded associated with
the closure of two of the Company's owned Clinical Business sites, including
severance related costs for two employees at these locations.
 
     Also during 1998, the Company recorded impairment charges of $6,056,019
related to the impairment of goodwill. Of this charge, $1,848,307 was related to
goodwill written off during the third quarter of 1998 related to the two
Clinical Business locations that were closed in September of 1998 due to their
poor operating performance and represented the remaining unamortized goodwill
allocated to these locations at the time of their purchase in 1996. The
remaining $4,207,712 was for goodwill associated with GFI.
 
     GFI, a subsidiary, was acquired in January 1996 for $6.0 million with
substantially all of the purchase price being allocated to goodwill.
Subsequently, pursuant to SFAS 121, the Company evaluated the recoverability of
the long-lived assets including intangibles of its GFI subsidiary. GFI's revenue
continued to decline and its net losses continued to increase since its
acquisition. In addition, the two principals responsible for the development of
GFI, prior to its purchase by the Company, left the Company and a new management
team was put in place. In the third quarter of 1998, after new management's
efforts to effect a turn around were exhausted, and concurrent with the
Company's planning process, it was determined that the possibility of recovering
the recorded value of the long-lived GFI assets through a sale of GFI, exclusive
of a sale of the entire Clinical Business was remote. In addition, it was
determined that GFI's future undiscounted cash flows were below the carrying
value of GFI's long-lived assets. Accordingly, during the third quarter of 1998,
the Company adjusted the carrying value of GFI's long-lived assets to their
estimated fair value of approximately $1.6 million, resulting in a non-cash
charge of $4,207,712. The estimated fair value was based on the purchase price
allocated to GFI pursuant to an initial offer from The West Company,
Incorporated to purchase the Clinical Business.

4.  NOTE RECEIVABLE -- OFFICER
 
     In September 1997, the Company loaned an officer of DataTRAK, Inc. $165,000
as part of a relocation package. The loan bore interest at the applicable
federal rate, adjusted on a monthly basis. The note, plus interest, was repaid
in 1998.
 
5.  FINANCING ARRANGEMENTS
 
     The Company has a line of credit agreement with a bank which provides for
borrowings up to $2.0 million that bears interest at rates not to exceed prime
(no amounts were outstanding at December 31, 1997 or 1998). The line of credit
agreement requires that the Company maintain investments of $2.0 million with
the bank. This line of credit is considered to be committed and is subject to
renewal at January 31, 2000.

subject to shareholder approval, to sell its Clinical Business to The West
Company, Incorporated. The sale of the clinical business will meet the
definition of a change of control as defined in each of the Company's share
option plans. Upon completion of the sale of the Clinical Business all 444,650
outstanding Common Share options will become fully vested, of which 150,283 of
these options have an exercise price less than the market value of the Company's
Common Shares on December 31, 1998.
 
     The 1996 Director Plan was amended, subject to shareholder approval, to
provide for the granting of a maximum of 175,000 options, which will increase
the number of Common Shares reserved for the exercise of Common Share options to
1,079,708. The 1996 Director Plan was also amended, subject to shareholder
approval, to allow for a three year vesting period for certain options. In 1998,
the Company's Board of Directors have approved the granting of a total of 70,000
Common Share options (excluded from the table above) to outside directors at an
exercise price of $4.19 per share, subject to shareholder approval of the
amendment to the 1996 Director Plan. Pursuant to APB 25, compensation expense
may be incurred in future periods related to these options, if the market value
of the Company's Common Shares is greater than the exercise price of the Common
Share options, upon approval of the amendment to the 1996 Director Plan.
 
12.  STOCK BASED COMPENSATION
 
     The Company has elected to follow APB 25 and related interpretations in
accounting for its employee and director stock options. As discussed below, the
alternative fair value accounting provided for under Financial Accounting
Standards Board Statement No. 123, "Accounting for Stock-Based Compensation"
("Statement No. 123") 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.
 
     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 1996, 1997 and 1998,
respectively: risk free interest rate of 5.0%, 6.0% and 5.5%, a volatility
factor of the expected market price of the Company's Common Shares of 0.53, 0.66
and 0.34, 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 1996, 1997 and 1998 was
$6.66, $5.18, and $1.91, 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:

13.  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. The Company did not make any matching or profit sharing
contributions in 1996, 1997 or 1998.
 
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.  SEGMENT INFORMATION
 
     The Company operates in two principal business segments: Clinical Business
and DataTRAK. The Clinical Business provides Phase I through IV clinical
research services, and over the counter product services. DataTRAK provides
technology and other services to assist in the timely completion of clinical
trials. During 1996, the Company operated only in the Clinical Business segment.
 
     The Company evaluates performance and allocates resources based on profit
or loss from operations before other income and expense and income taxes. The
accounting policies of the reportable segments are the same as those described
in the summary of significant accounting policies. There have been no
intersegment sales.

     The Company's reportable segments are business units that offer different
services utilized in the performance of clinical trials. The reportable segments
are managed separately because they offer separate and distinct services to
customers in the clinical research industry.

16.  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. 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.
 
     The following table sets forth the computation of basic and diluted
earnings per share.

of the Sellers as of the date on which the Estimated Closing Date Net Working
Capital is determined, and such other information which Buyer may require in
connection therewith. The parties hereto shall set forth their agreement with
respect to the Estimated Closing Date Net Working Capital in a written

     means of wire transfer of immediately available funds to an account
     designed by the Escrow Agent, in writing, at least three (3) business days

     pursuant to the Escrow Agreement for (A) the payment of any sums due to the

     Agreement.
 
     2.4  FINAL CLOSING DATE BALANCE SHEET; CALCULATION OF CLOSING DATE NET

     (a) As soon as practicable, but in no event later than sixty (60) days
after the Closing Date, Buyer will prepare and deliver to Sellers a statement of
Acquired Assets and Assumed Liabilities as of the Closing Date setting forth
Buyer's calculation of the Closing Date Net Working Capital by reference thereto
(such statement of Acquired Assets and Assumed Liabilities, including Buyer's
calculation of Closing Date Net Working Capital, being referred to as the "Final
Closing Date Statement"). The Final Closing Date Statement shall be prepared in
a manner consistent with the preparation of the Financial Statement (provided
that the Financial Statements have been prepared in accordance with GAAP
consistently applied).
 
     (b) Upon the completion of the Final Closing Date Statement, a copy thereof
shall be delivered to Sellers. Sellers shall have the right, for a period of
fifteen (15) days following their receipt thereof, to review the Final Closing
Date Statement to determine whether the Final Closing Date Statement was
prepared in accordance with the provisions hereof. If, following such review,
Sellers determine that the Final Closing Date Statement was not prepared in
accordance with the provisions hereof and that Buyer's calculation of Closing
Date Net Working Capital is in error as a result thereof, Sellers shall so
notify Buyer. For a period of fifteen (15) days following the receipt of such
notice, Buyer and Sellers shall attempt to resolve any such dispute with respect
to the Final Closing Date Statement. If, at the expiration of such fifteen (15)
day period, Buyer and Sellers are not able to resolve such dispute, within the
three (3) day period immediately following the expiration of such fifteen (15)
day period, the Buyer and Sellers shall promptly submit to the Pittsburgh,
Pennsylvania office of any "big five" firm of independent, certified public
accountants recommended by the Pennsylvania Institute of Certified Public
Accountants (provided that such accountants do not then serve as accountants to
Buyer or Seller), which firm shall resolve all matters in dispute with respect
to the Final Closing Date Balance Sheet within the fifteen (15) day period
immediately following such submission and whose determination shall be final,
binding and conclusive upon Buyer and Sellers. The fees of any such independent,
certified public accounting firm shall be borne equally by Buyer and Sellers.
 
     (c) At a supplemental closing to be held within the later of ninety (90)
days after the Closing Date or ten (10) days after the final determination of
the Final Closing Date Statement and calculation of the Closing Date Net Working
Capital pursuant to Section 2.4(b) (the "Supplemental Closing"), payment shall
be made from Buyer to Sellers or Sellers to Buyer, as appropriate, to take into
account any difference between the Estimated Purchase Price (based upon the
Estimated Closing Date Net Working Capital) and the Purchase Price (based upon
the actual Closing Date Net Working Capital). Such difference, if any, will be
paid as follows:
 
          (i) If the Purchase Price exceeds the Estimated Purchase Price, at the
     Supplemental Closing, Sellers will be entitled to receive from Buyer an
     amount equal to such excess, which shall be paid by Buyer by means of wire
     transfer of immediately available funds to an account or accounts
     designated by Seller in writing.
 
          (ii) If the Estimated Purchase Price exceeds the Purchase Price, Buyer
     will be entitled to receive from the Escrow Holder funds from the Escrow
     Deposit in an amount equal to such excess, which amount shall be paid by
     Escrow Holder pursuant to the terms of the Escrow Agreement at the
     Supplemental Closing by means of wire transfer of immediately available
     funds to an account or accounts designated by Buyer in writing. If the
     amount by which the Estimated Purchase Price exceeds the Purchase Price is
     greater than the Escrow Deposit, Sellers will pay to Buyer an amount equal
     to such excess which shall be paid by Sellers at the Supplemental Closing
     by means of wire transfer of immediately available funds to an account or
     accounts designated by Buyer in writing.

     2.5  PURCHASE PRICE ADJUSTMENT FOR UNCOLLECTED RECEIVABLES. Notwithstanding

the Buyer's customary collection practices (without resort to legal
proceedings), within one hundred eighty (180) days after the Closing Date
(collectively, the "Uncollected Receivables") there shall be a dollar-for-dollar
reduction in the Purchase Price in an amount equal to the aggregate amount of
the Uncollected Receivables. Any adjustment to the Purchase Price pursuant to
this Section 2.5 shall be paid in the manner provided by Section 2.4(c)(ii).
Following the satisfaction by the Sellers of all of their obligations under this
Section 2.5, the Buyer shall, if requested by the Sellers, assign and transfer
(without recourse, representation, or warranty) to Sellers all of Buyer's right,
title, and interest in, to, and under the Uncollected Receivables, pursuant to a
written instrument of assignment reasonably satisfactory to Buyer and Sellers;
provided, however, Sellers shall not disrupt the Clinical Business conducted by
Buyer in connection with any effort by Sellers to collect the Uncollected
Receivables following such assignment and transfer thereof. The parties further
agree that if the Buyer collects in cash an aggregate amount in respect of
billed and unbilled accounts receivable of the Sellers included in the Acquired
Assets (net of any reserve therefor reflected in the Final Closing Date Balance
Sheet) which is in excess of such billed and unbilled accounts receivable
reflected in the Final Closing Date Balance Sheet (net of the aforesaid reserve)
as of the date which is one hundred eighty (180) days after the Closing Date,
the Purchase Price shall be increased, dollar-for-dollar, by an amount equal to
such excess (such Purchase Price increase to be paid in the manner provided by

          (i) Audited consolidated and consolidating balance sheets of
     Collaborative and its subsidiaries (including the Selling Subsidiaries) as
     at the close of each of the years December 31, 1995, December 31, 1996, and
     December 31, 1997, inclusive, and the related consolidated and
     consolidating statements of income, changes in stockholders' equity, and
     cash flow of collaborative and its subsidiaries (including the selling
     Subsidiaries) for each of the fiscal years then ended, all on a comparative
     basis, together with the notes thereto and the report thereon of Seller's
     Accountant (the "Prior Financial Statements"); and
 
          (ii) a consolidated and consolidating balance sheet of Collaborative
     and its subsidiaries as at September 30, 1998, and the related internally
     prepared consolidated and consolidating statements of income, changes in
     stockholders' equity and cash flow for the nine (9) month period then ended
     (which, together with any financial statements delivered pursuant to
     Section 5.11, shall be collectively referred to as the "Interim Financial
     Statements").
 
     (b) The Financial Statements fairly present, in all material respects, the
financial condition and the results of operations, changes in stockholders'
equity, and cash flow of Collaborative and its subsidiaries as at the respective
dates of and for the periods referred to in such Financial Statements, all in
accordance with GAAP, subject, in the case of interim financial statements, to
normal year-end adjustments (the effect of which will not, individually or in
the aggregate, be materially adverse), and the Financial Statements reflect the
consistent application of such accounting principles throughout the periods
involved. Except to the extent provided otherwise in such Financial Statements,
(i) adequate provision was made in the Financial Statements for doubtful

covered by such Financial Statements was necessary, under GAAP, for Liability on
account of warranties or with respect to the Clinical Business. Any significant
items of income or expense which were unusual or of a nonrecurring nature were
separately disclosed in the Financial Statements.

Sellers' Knowledge, all Facilities currently used by Sellers lie wholly within

encroach upon the property of, or otherwise conflict with the property rights
of, any other Person. The use and operation of such Facilities are in compliance

other improvements and fixtures which comprise the Facilities (i) are free of
any structural or engineering defects, (ii) are in good repair and condition,
ordinary wear and tear excepted, and (iii) are free from any latent defects and
(iv) suitable for their intended use.
 
     3.7  NO UNDISCLOSED LIABILITIES.  Except as set forth in Schedule 3.7 or

become due pursuant to those Tax Returns or otherwise, or pursuant to any
assessment received by Sellers, except such Taxes, if any, as are listed in

reserves (determined in accordance with GAAP) have been provided in the Interim
Balance Sheet.
 
     (b) The charges, accruals, and reserves with respect to Taxes on the books
of Sellers are adequate (determined in accordance with GAAP) and are at least
equal to Sellers liability for Taxes. There exists no proposed tax assessment
against Seller to Seller Knowledge except as disclosed in Schedule 3.8. All
Taxes that Seller is or was required by Legal Requirements to withhold or
collect have been duly withheld or collected and, to the extent required, have
been paid to the proper Governmental Body or other Person.
 
     (c) All Tax Returns filed by Sellers (or that include Sellers on a
consolidated basis) are true, correct, and complete in all material respects.
 
     (d) No audit or examination by any Tax authority is pending with respect to

such later date as the parties may agree upon.
 
     9.2  EFFECT OF TERMINATION.  Each party's right of termination under
Section 9.1 is in addition to any other rights it may have under this Agreement

the parties under this Agreement will terminate, except that the obligations in

representations, warranties, covenants, and obligations in this Agreement, the
Schedules to this Agreement, and the Related Agreement will survive the Closing.
The right to indemnification, reimbursement, or other remedy based on such
representations, warranties, covenants, and obligations will not be affected by
any investigation conducted with respect to, or any Knowledge acquired (or
capable of being acquired) about the accuracy or inaccuracy of or compliance
with, any such representation, warranty, covenant, or obligation. The waiver of
any condition based on the accuracy of any representation or warranty, or on the
performance of or compliance with any covenant or obligation, will not affect

     10.4  PROCEDURE FOR INDEMNIFICATION -- THIRD PARTY CLAIMS.
 
     (a) Promptly after receipt by an indemnified party under Section 10.2 or
10.3 of notice of the commencement of any Proceeding against it, such
indemnified party shall, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement of
such claim, but the failure to notify the indemnifying party will not relieve
the indemnifying party of any liability that it may have to any indemnified
party, except to the extent that the indemnifying party demonstrates that the
defense of such action is materially prejudiced by the indemnifying party's
failure to give such notice.
 
     (b) If any Proceeding referred to in Section 10.4(a) is brought against an
indemnified party and it gives notice to the indemnifying party of the
commencement of such Proceeding, the indemnifying party shall be
 
                                      A-27
<PAGE>   119
 
entitled to participate in such Proceeding and, if (i) the indemnifying party
acknowledges in writing to the indemnified party, without qualification or
limitation, its obligation to indemnify the indemnified party for all Damages
arising from such Proceeding and (ii) provides the indemnified party with
satisfactory assurances that it has the financial ability to fully indemnify the
indemnified party for such Damages, the indemnifying party shall assume the
defense of such Proceeding with counsel reasonably satisfactory to the
indemnified party. If notice is given to an indemnifying party of the
commencement of any Proceeding and the indemnifying party does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.
 
     (c) Notwithstanding the foregoing, if an indemnified party determines in
good faith that there is a reasonable probability that a Proceeding may
adversely affect it or its Related Persons other than as a result of monetary
damages for which it would be entitled to indemnification under this Agreement,
or if an indemnified party reasonably believes that it may not receive the
indemnification to which it may be entitled from the indemnifying party, the
indemnified party may, by notice to the indemnifying party, assume the exclusive
right to defend, compromise, or settle such Proceeding, but the indemnifying
party will not be bound by any determination of a Proceeding so defended or any
compromise or settlement effected without its consent (which may not be
unreasonably withheld).
 
     10.5  LIMITATION OF CLAIMS.
 
     (a) Except as set forth below, there shall be no liability under or with
respect to any of the warranties or representations of Sellers or Buyer in or
under this Agreement or in any Schedule hereto, unless a claim for indemnity is
given by the party seeking indemnification within the six (6) month period
immediately following the Closing Date, except for Damages arising as a result
of, or in connection with, or with respect to the following, with respect to
which there shall be no limitation as to the time period within which an
indemnity claim must be made by Buyer hereunder: (i) the Excluded Liabilities;
or (ii) the Breach of any agreements or covenants of any Seller hereunder.
 
     (b) The maximum aggregate amount recoverable by Buyer from Sellers pursuant
to this Section 10 arising by reason or Breach of a representation or warranty
of Sellers hereunder shall be limited to the sum of One Million Dollars
($1,000,000); provided, however, (i) the Buyer shall be entitled to
indemnification hereunder only when the aggregate of all such claims exceeds One
Hundred Thousand Dollars ($100,000) (the "Threshold Amount"), and (ii) all such
claims shall be recoverable by the Buyer after the Threshold Amount of claims
has been reached.
 
     (c) The maximum amount recoverable by Sellers from Buyer pursuant to this
Section 10 arising by reason or Breach of a representation or warranty of Buyer
hereunder shall be limited to the sum of One Million Dollars ($1,000,000);
provided, however, (i) the Sellers shall be entitled to indemnification
hereunder only when the aggregate of all such claims exceed the Threshold
Amount, and (ii) all such claims shall be recoverable by the Sellers after the
Threshold Amount has been reached.
 
     (d) Anything to the contrary set forth in this Section 10 notwithstanding,
the provisions of this Section 10 shall not apply to any Damages relating to, or
arising out of, or in connection with, the fraud of any party hereto.

cumulative and not alternative. Neither the failure nor any delay by any party
in exercising any right, power, or privilege under this Agreement or the

require Sellers to transfer and convey at the Closing any of the Acquired Assets
specified by Buyer to one or more affiliates of Buyer, and (c) assign or pledge
all of its rights hereunder to the financial institutions providing financing to

preceding sentence, this Agreement will apply to, be binding in all respects
upon, and inure to the benefit of the successors and permitted assigns of the

give any Person other than the parties to this Agreement any legal or equitable
right, remedy, or claim under or with respect to this Agreement or any provision
of this Agreement. This Agreement and all of its provisions and conditions are
for the sole and exclusive benefit of the parties to this Agreement and their

     (a) Claims Against Escrow Fund.  Sellers and Buyer, as the case may be,
shall have the right, in accordance with the procedures more fully set forth
below, to make a claim against the Escrow Fund (an "Escrow Fund Claim") for and
with respect to the following matters for which amounts are or may be due and
owing to the Sellers or the Buyer, as the case may be:
 
          (i) the payment of sums due to the Buyer under the provisions of
     Section 2.4(c)(ii)(the "Estimated Purchase Price Adjustment") and Section
     2.5 (the "Accounts Receivable Adjustment") of the Purchase Agreement.
 
          (ii) any claim for indemnification made by or on behalf of Buyer
     against the Sellers under Section 10.2 of the Purchase Agreement
     ("Indemnity Claim").
 
          The occurrence or existence of any event or circumstance which gives
     rise to a right in favor of the Buyer to make an Escrow Fund Claim shall be
     referred to herein as a "Claim Event."
 
     (b) Notification of Claim Events.  Buyer shall promptly notify the Sellers
and the Escrow Agent in writing of any Claim Event of which the Buyer has
knowledge and its desire to make an Escrow Fund Claim as a result thereof (a
"Claim Notice"), which Claim Notice shall be in the form of Exhibit "B" attached
hereto. In addition, the Escrow Agent shall promptly send a copy of the Claim
Notice to the Sellers. Each Claim Notice shall be signed by an authorized
officer of the Buyer, describe whether the Claim Event relates to the Estimated
Purchase Price Adjustment or an Accounts Receivable Adjustment (as provided by
Section 5(a)(i) hereof) and/or an Indemnity Claim (as provided by Section
5(a)(ii) hereof), set forth the amount of each Escrow Fund Claim and, with
respect to third-party Indemnity Claims, contain copies of any and all
correspondence, information, complaints, and other information relating to such
third-party indemnity claims and provide that the Claim will be paid unless an
objection is made by the Sellers within twenty (20) days.
 
     (c) Disbursements.  Buyer and Sellers shall jointly notify and direct the
Escrow Agent to make the following disbursements from the Escrow Fund to the
extent available for satisfaction of Escrow Fund Claims:
 
          (i) subject to the provisions of Section 5(d) hereof, within twenty
     (20) days following the Escrow Agent's receipt of a Claim Notice in respect
     of an Estimated Purchase Price Adjustment or Accounts Receivable
     Adjustment, the Escrow Agent shall disburse an amount from the Escrow to
     the Buyer, equal to the amount set forth in the Claim Notice. Buyer and
     Sellers covenant and agree to execute and deliver a joint Claim Notice
     pursuant to this Section 5(c)(i) as soon as possible after any Estimated
     Purchase Price Adjustment or Accounts Receivable Adjustment has been
     determined under the Purchase Agreement.
 
          (ii) subject to the provisions of Section 5(d) hereof, within twenty
     (20) days following the Escrow Agent's receipt from the Buyer of a Claim
     Notice in respect of an Indemnity Claim, the Escrow Agent shall disburse an
     amount from the Claims Escrow equal to the amount of the Escrow Fund Claim
     (together with any actual and reasonable attorneys' fees, costs, and other
     expenses incurred by the Buyer
 
                                      A-36
<PAGE>   128
 
     in connection therewith, all of which shall be itemized in the Claim
     Notice) to the Buyer or, at the Buyer's direction, directly to the
     claimant. In the event that a Claim Notice is issued by the Buyer with
     respect to an Indemnity Claim which has not been settled and the amount of
     which has not been determined, the Escrow Agent shall reserve and not
     disburse from the Escrow Fund an amount equal to the Buyer's reasonable
     estimate of the potential amount of the Escrow Fund Claim relating thereto;
     provided, however, notwithstanding the foregoing, the Buyer shall have the
     right, at any time upon written notice to the Escrow Agent, to request and
     receive disbursements from the Escrow Fund with respect to such unsettled
     Indemnity Claim to the extent necessary to pay or reimburse the Buyer for
     actual and reasonable attorneys' fees, costs, and other expenses incurred,
     or to be incurred, by the Buyer in connection therewith, provided that such
     fees and expenses are itemized in the Claim Notice or any supplement
     thereto.
 
          (iii) subject to the provisions of Section 5(d) hereof, one hundred
     and eighty (180) days after the Closing Date (as defined in the Purchase
     Agreement), the Escrow Agent shall release from the Escrow Fund and
     disburse to the Sellers the balance of the Escrow Fund (the "Final
     Payment"). Notwithstanding anything contained in this clause (iii) to the
     contrary, in no event shall amounts be disbursed from the Escrow Fund
     pursuant hereto which are in excess of the aggregate amount of outstanding
     Indemnity Claims of Buyer.
 
     (d) Objection Notices.  Notwithstanding anything contained herein to the
contrary, in the event that the Escrow Agent receives a written objection to any
contemplated disbursement of the Escrow Fund under Sections 5(c)(i), 5(c)(ii),
or 5(c)(iii) hereof prior to the expiration of the twenty (20) day period
referred to therein or the Release Date, as appropriate, describing in detail
the reasons for which such an objection is being made and certified by an
authorized officer of the Sellers or the Buyer (an "Objection Notice"), the
Escrow Agent shall promptly notify the parties hereto and provide such parties
with a copy thereof. The Escrow Agent shall thereafter await settlement and
resolution of the dispute relating to the Escrow Fund Claim described in the
Objection Notice pursuant to the provisions of this Section 5(d). Buyer and the
Sellers shall thereafter use their reasonable efforts to settle and resolve any
dispute which is set forth in an Objection Notice in a mutually acceptable
fashion within thirty (30) days following the their receipt of the Objection
Notice from the Escrow Agent. If the Buyer and the Sellers are able to so settle
and resolve such dispute within the above-described thirty (30) day period (or
any written extension thereof) pursuant to a written settlement agreement duly
executed by the Buyer and the Sellers, they shall provide joint written
instructions to the Escrow Agent directing the Escrow Agent to make a
disbursement of the Escrow Fund in a manner consistent with the settlement
agreement. If the Buyer and the Sellers are unable to reach such a settlement,
either the Buyer or the Sellers may pursue any and all rights and remedies
available to them under the Purchase Agreement and the Related Agreements. In
connection with any Objection Notice issued pursuant hereto, the Escrow Agent
retains all of its rights under Section 9(e) notwithstanding anything contained
herein to the contrary. In the event that the Buyer and the Sellers have
provided joint written instructions to the Escrow Agent with respect to an
Escrow Fund Claim and a disbursement from the Escrow Fund to be made by the
Escrow Agent in connection therewith, the Escrow Agent may assume that an
Objection Notice will not be issued subsequent thereto regarding such
disbursement and the Sellers shall be deemed to have waived their right to issue
an Objection Notice with respect to such disbursement.
 
     6.  Adjustments to Escrow Fund.
 
     (a) Reduction to Escrow Fund.  Any disbursements from the Escrow Fund
pursuant to Section 5 hereof shall reduce the Escrow Fund, dollar-for-dollar, by
an amount equal to such disbursement.
 
     (b) Earnings on Escrow Fund.  Earnings on the Purchase Price Adjustment
Reserve Escrow and the Claims Escrow shall be distributed to Collaborative in
conjunction with the Final Payment, pursuant to Section 5(c)(iii) hereof in
accordance with the terms of the investments into which the Escrow Fund is
invested.
 
     7.  Term of Escrow.  This Agreement shall remain in effect until the date
on which the Escrow Fund has been fully disbursed pursuant hereto. Upon the
termination of this Agreement, as provided in this Section 7, the undisbursed
portion of the Escrow Fund shall be disbursed by the Escrow Agent to the
Sellers.

<PAGE>   129
 
     8.  No Limitation of Remedies.  Notwithstanding the method and procedure
for the making and satisfaction of Indemnity Claims hereunder, nothing contained
in this Agreement shall limit the Buyer's ability to pursue and enforce any and
all other legal and equitable rights and remedies which it may have against any
of the Sellers in connection with any Indemnity Claims or any other matter
related or pertaining to the Purchase Agreement or the Contemplated
Transactions.
 
     9.  Obligations of Escrow Agent.
 
     (a) Nature of Duties.  The duties of the Escrow Agent hereunder shall be
entirely administrative and not discretionary. The Escrow Agent shall be
obligated to act only in accordance with the provisions of this Agreement and/or
written instructions received by it from the Buyer and the Sellers as provided
in this Agreement, except that the Escrow Agent shall comply with any final and
unappealable order, judgment or decree of any court of competent jurisdiction
and shall not be liable as a result of its compliance with such order, judgment
or decree.
 
     (b) No Tax Liability.  The Escrow Agent shall not be liable for any tax on
any earnings on the Escrow Fund.
 
     (c) Reliance on Documents.  The Escrow Agent may rely absolutely upon the
genuineness and authorization of the signature and purported signature of any
party upon any instruction, notice, release, receipt or other document delivered
to it pursuant to this Agreement.
 
     (d) Indemnification.  Sellers and Buyer agree that the Escrow Agent shall
not be liable for any damages or other payments pursuant to any suit, claim or
cause of action which either Sellers or Buyer may commence. Each of the Sellers
and the Buyer further agree to indemnify the Escrow Agent against and from
one-half ( 1/2) of any and all claims, demands, costs, liabilities and expenses,
including counsel fees, which may be asserted against the Escrow Agent or to
which it may be exposed or which it may incur by reason of either such party's
breach of any term or provisions hereof.
 
     (e) Disputes.  Notwithstanding any other provision of this Agreement, if
any dispute or difference arises between Buyer and Sellers or if any conflicting
demand shall be made upon the Escrow Agent, the Escrow Agent shall not be
required to determine the same or take any action thereon. Rather, the Escrow
Agent may:
 
          (i) await settlement of the controversy by appropriate legal
     proceedings; or
 
          (ii) may file suit in interpleader with any court for which
     jurisdiction is proper under Section 11.5 of the Purchase Agreement for the
     purpose of having the respective rights of the parties adjudicated.
 
The Escrow Agent, upon initiation of such suit, may deposit the Escrow Fund with
the court and, upon giving notice thereof to the parties hereto, the Escrow
Agent shall be fully released and discharged from all further obligations
hereunder with respect to all funds held under this Agreement.
 
     (f) Liability.  The Escrow Agent shall not be liable for any error of
judgment, or for any act done or omitted by it, or for any mistake in fact or
law, or for anything that it may do or refrain from doing in connection
herewith; provided, however, that notwithstanding any other provision in this
Agreement, the Escrow Agent shall be liable for its willful misconduct and gross
negligence.
 
     (g) Advice; Consultation.  The Escrow Agent may seek the advice of legal
counsel selected with reasonable care in the event of any dispute or question as
to the construction of any of the provisions of this Agreement or its duties
hereunder, and it shall incur no liability and shall be fully protected in
respect of any action taken, omitted or suffered by it in good faith.
 
     (h) Delegation.  The Escrow Agent may execute any of its powers or
responsibilities hereunder and exercise any rights hereunder either directly or
by or through agents or attorneys selected by it with reasonable care.
 
     (i) Compensation; Reimbursement.  For and in consideration of the services
rendered by the Escrow Agent pursuant hereto, the Escrow Agent shall receive
those fees and charges referenced on Exhibit "C" attached hereto. The Escrow
Agent shall also be entitled to receive reimbursement for any reasonable costs
 
                                      A-38
<PAGE>   130
 
and expenses which it incurs in connection with the performance of its duties
hereunder. The Buyer and the Sellers shall each be responsible for one-half
(1/2) of all fees, costs, and expenses due and payable to the Escrow Agent
under this Section 9(i), all of which shall be promptly paid within thirty (30)
days following any written request by the Escrow Agent.
 
     (j) Survival.  All provisions of this Section 9 shall survive the
termination of this Agreement and the resignation by or removal of the Escrow
Agent.
 
     10.  Cooperation.  Buyer and Sellers shall provide to the Escrow Agent all
instruments and documents within their respective powers to provide that are
necessary for the Escrow Agent to perform its duties and responsibilities
hereunder.
 
     11.  Resignation and Removal of the Escrow Agent.
 
     (a) Resignation; Removal.  The Escrow Agent may resign as Escrow Agent
hereunder upon giving at least sixty (60) days' prior written notice thereof to
Sellers and Buyer and returning to the Buyer and the Sellers, as appropriate,
the unearned portion of any fees paid to the Escrow Agent under Section 9(i)
hereof. In addition, the Escrow Agent may be removed and replaced on a date
designated in a written instrument signed by the Buyer and the Sellers and
delivered to the Escrow Agent and, upon such removal and replacement, the Escrow
Agent shall return to the Buyer and the Sellers, as appropriate, the unearned
portion of any fee payable to the Escrow Agent under Section 9(i) hereof.
Notwithstanding the foregoing, no such resignation or removal shall be effective
until a successor escrow agent has acknowledged its appointment as such as
provided in Section 11(c) hereof. In either event, upon the effective date of
such resignation or removal, the Escrow Agent shall deliver the property
comprising the Escrow Fund to such successor escrow agent, together with such
records maintained by the Escrow Agent in connection with its duties hereunder
and other information with respect to the Escrow Fund as such successor escrow
agent may reasonably request.
 
     (b) Successor Escrow Agent.  If a successor escrow agent shall not have
acknowledged its appointment as such as provided in Section 11(c) below, in the
case of a resignation, prior to the expiration of sixty (60) calendar days
following the date of a notice of resignation or, in the case of a removal, on
the date designated for the Escrow Agent's removal, as the case may be, because
the Sellers and Buyer are unable to agree on a successor escrow agent or for any
other reason, the Escrow Agent may select a successor escrow agent and any such
resulting appointment shall be binding upon all of the parties to this
Agreement.
 
     (c) Release of Escrow Agent.  Upon written acknowledgment by a successor
escrow agent appointed in accordance with the provisions of this Section 11 of
its agreement to serve as escrow agent hereunder and the receipt of the property
then comprising the Escrow Fund and the materials described in Section 11(a)
hereof, the Escrow Agent shall be fully released and relieved of all duties,
responsibilities and obligations under this Agreement, and such successor escrow
agent shall for all purposes hereof be the Escrow Agent.
 
     (d) Sale, Merger, Consolidation, Conversion of Escrow Agent.  Any
corporation, association or other entity into which the Escrow Agent may be
converted or merged, or with which it may be consolidated, or to which it may
sell or otherwise transfer all or substantially all of its corporate trust
assets and business or any corporation, association or other entity resulting
from any such conversion, sale, merger, consolidation or other transfer to which
it is a party, ipso facto, shall be and become successor escrow agent hereunder,
vested with all of the rights, powers, discretions, duties, obligations,
immunities, privileges and all other matters as was its predecessor, without the
execution or filing of any instrument or any further act on the part of the
parties hereto, notwithstanding anything herein to the contrary.
 
     12.  Notices.  All notices, consents, waivers, and other communications
under this Agreement must be in writing and will be deemed to have been duly

                           NON-COMPETITION AGREEMENT
 
     THIS NON-COMPETITION AGREEMENT (the "Agreement") made this      day of
            , 1999, by and among COLLABORATIVE CLINICAL RESEARCH, INC., an Ohio

THE WEST COMPANY, INCORPORATED, a Pennsylvania corporation, with offices at 101
Gordon Drive, Lionville, Pennsylvania 19341 (the "Buyer").
 
                                   BACKGROUND
 
     A.  The Sellers have heretofore been engaged in the business of providing
clinical research and "over-the-counter" drug testing and related services
including (i) the contract clinical research business and (ii) the site
management services business (such businesses, together with any and all
business activities incidental thereto, being collectively referred to herein as
the "Business Activities").
 
     B.  Under an Asset Purchase Agreement dated December 21, 1998 (the "Asset
Purchase Agreement") among the Sellers and the Buyer, the Buyer has agreed to
purchase substantially all of the properties and assets of the Sellers relating
to the Business Activities and thereafter to engage in the Business Activities.
 
     C.  One of the conditions precedent to the consummation by the Buyer of the
purchase, sale, and other transactions contemplated by the Assets Purchase
Agreement (collectively, the "Transactions"), which are being completed on the
date hereof, is that the Sellers enter into this Agreement for the purpose of
preserving, for the Buyer's benefit, the good will, proprietary rights and going
business value of the business and assets purchased from the Buyer.
 
     NOW, THEREFORE, for the purposes set forth above and in consideration of
the mutual covenants contained herein, and intending to be legally bound hereby,
the parties agree as follows:
 
     1.  Agreement Not to Compete.
 
     (a) The Sellers hereby acknowledge and recognize the highly competitive
nature of the Business Activities and accordingly agree that the Sellers will
not, during and for a three (3) year period commencing with the date hereof,
(the "Non-Competition Period"), directly or indirectly, (i) engage in any of the
Business Activities, whether such engagement is as an officer, director,
proprietor, employee, partner, investor (other than as a passive investor in
less than five percent (5%) of the outstanding capital stock of a publicly
traded corporation), consultant, advisor, agent, or other participant in another
business, within the geographic territory in which the Buyer is conducting
Business Activities or actively pursuing business in order to conduct Business
Activities thereat (the "Restricted Territory"); (ii) assist others in engaging
in any of the Business Activities in the manner described in the foregoing
clause (i); or (iii) solicit or induce any person who then is or was an employee
of the Sellers to terminate his or her employment or offer employment to or hire
or engage any such person. Notwithstanding the restrictions contained in this
Section 1(a) or Section 2 hereof, Sellers shall be permitted to (i) engage in
the DataTRAK business described on Exhibit "A" hereto, and (ii) retain a copy of
the IMIC data base (which includes a list of customers and prospective customers
of Sellers), provided that (A) such data base and related information is used
solely and exclusively by Sellers in connection with the DataTRAK business
described on Exhibit "A" hereto and (B) such data base and related information
is not copied, reproduced or shared or divulged to any other person or entity.
 
     (b) Notwithstanding the provisions of Section 1(a) of this Agreement to the
contrary, the parties expressly agree that (i) the Sellers, including DataTRAK,
shall be permitted to engage in a sale (whether assets or stock), merger or
other similar transaction, in whole or part, to any other party (herein
collectively
 
                                      A-47
<PAGE>   139
 
referred to as "Purchaser"), and (ii) the Sellers, including DataTRAK, may
become a member or otherwise participate in a consortium involving other
companies ("Consortium"), either as the leader or a member of such Consortium,
for the purpose of creating, developing or implementing electronic data capture
technology and related electronic data handling services, so long as the
Purchaser, the Consortium, and members of the Consortium, as appropriate, shall
execute a written instrument under which it or they shall covenant and agree to
be bound by (1) the restrictions contained in clause (iii) of Section 1(a)
hereof, and (2) the provisions of Section 2 hereof (subject to the provisions of
clause (kk) of the last sentence of Section 1(a) hereof), which written
instrument shall be satisfactory, in form and substance, to Buyer.
 
     2.  Confidentiality.  The Sellers agree to hold in a fiduciary capacity for
the benefit of the Buyer, all secret and confidential information, knowledge,
techniques of doing business, or data (including customer and prospect lists)
involving or related to the Clinical Business (as defined in the Asset Purchaser
Agreement) ("Confidential Information") and will not, without Buyer's prior
written consent, at any time during or after the Non-Competition Period,
communicate or divulge any such Confidential Information to any individual,
firm, partnership, corporation, or other entity, nor shall the Sellers, at any
time during or after the Non-Competition Period, make use of any Confidential
Information for the Sellers' own purposes or for the benefit of any person or
other entity under any circumstances, except and to the extent (i) any of the
foregoing is in the public domain (other than as a result of the Sellers' breach
of this Section 2), or (ii) such disclosure is required by law or appropriate
court order and written notice thereof is provided to the Buyer not less than
ten (10) days prior to such disclosure.
 
     3.  Reformation.  It is expressly understood and agreed that, although the
Sellers and the Buyer consider the restrictions contained in Sections 1 and 2
hereof to be reasonable for the purpose of preserving for the Buyer the good
will, proprietary rights and going business value of the business and assets
acquired by the Buyer, if a final judicial determination is made by a court
having jurisdiction that the time or territory or any other restriction
contained in Sections 1 or 2 hereof is an unreasonable or otherwise
unenforceable restriction against the Sellers, the provisions of Sections 1 or 2
hereof, as appropriate, shall not be rendered void, but shall be deemed amended
to apply as to such maximum time and territory and to such other extent as such
court may judicially determine or indicate to be reasonable.
 
     4.  Injunctive Relief.  Sellers acknowledge and agree that the Buyer's
remedy at law for a breach or threatened breach of any of the provisions of
Sections 1 or 2 hereof would be inadequate and, in recognition of that fact, in
the event of a breach or threatened breach by the Sellers of the provisions of
Sections 1 or 2 hereof, it is agreed that, in addition to its remedy at law, the
Buyer shall be entitled to, without posting any bond or other security,
equitable relief in the form of specific performance, temporary restraining
order, temporary or permanent injunction, or any other equitable remedy which
may then be available and the Sellers agree not to oppose the Buyer's request
for any of the above relief. Nothing herein contained shall be construed as
prohibiting the Buyer from pursuing any other rights and remedies available to
it for such breach or threatened breach.
 
     5.  Extension of Non-Competition Period.  The Non-Competition Period shall
be automatically extended for any period of time during which the Sellers have
breached any of the provisions hereof.
 
     6.  Waivers.  The waiver by the Buyer of a breach or threatened breach of
any provision of this Agreement by the Sellers shall not operate or be construed
as a waiver of any subsequent breach or threatened breach by the Sellers.
 
     7.  Assignment.  This Agreement shall not be assignable by the Sellers
without the prior written consent of the Buyer except as permitted and required
by Section 1(b) hereof. The Buyer may, upon written notice to but without the
consent of the Sellers, assign its rights hereunder to any party including,
without limitation, any successor of its business.
 
     8.  Governing Law.  This Agreement shall be governed by and construed in
accordance with the domestic, internal laws (but not the law or conflict of
laws) of the Commonwealth of Pennsylvania.
 
     9.  Binding Effect.  Subject to Section 7 hereof, the provisions of this
Agreement are for the benefit of the Buyer and may be enforced by the Buyer and
the Buyer's successors and assigns.

     10.  Joinder by Future Subsidiaries.  Subject to the provisions of Section
1(b) hereof, the Sellers shall cause any and all future subsidiaries of any
Seller to join in and become a party as a Seller under this Agreement pursuant
to and in accordance with a joinder hereto which is satisfactory, in form and
substance, to the Buyer.
 
     IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
caused this Agreement to be executed the day and year first written above.

                           NON-COMPETITION AGREEMENT
 
     THIS NON-COMPETITION AGREEMENT (the "Agreement") made this        day of
       , 1999, by and between DR. JEFFREY A. GREEN ("Dr. Green"), an adult
individual residing at        and THE WEST COMPANY, INCORPORATED, a Pennsylvania
corporation, with offices at 101 Gordon Drive, Lionville, Pennsylvania 19341
(the "Buyer").
 
                                   BACKGROUND
 
     A. Dr. Green has heretofore been an officer of Collaborative Clinical
Research, Inc. ("Collaborative") and GFI Pharmaceutical Services, Inc. and
Collaborative Holdings, Inc., which are wholly-owned subsidiaries of
Collaborative (Collaborative and such subsidiaries being collectively referred
to herein as the "Sellers"), and as such, possesses substantial expertise with
respect to the Business Activities (as defined below) conducted by the Sellers
prior to the date hereof.
 
     B. The Sellers have heretofore been engaged in the business of providing
clinical research and "over-the-counter" drug testing and related services
including (i) the contract clinical research business and (ii) the site
management services business (such businesses, together with any and all
business activities incidental thereto, being collectively referred to herein as
the "Business Activities").
 
     C. Under an Asset Purchase Agreement dated December 21, 1998 (the "Asset
Purchase Agreement") among the Sellers and the Buyer, the Buyer proposes to
purchase substantially all of the properties and assets of the Sellers and
thereafter to engage in the Business Activities.
 
     D. In light of the Dr. Green's position as an officer of the Sellers, and
Dr. Green's major contributions in the past to the growth and development of the
Sellers, one of the conditions precedent to the consummation by the Buyer of the
purchase, sale, and other transactions contemplated by the Assets Purchase
Agreement (collectively, the "Transactions"), is that Dr. Green enter into this
Agreement for the purpose of preserving, for the Buyer's benefit, the good will,
proprietary rights and going business value of the business and assets purchased
from the Sellers.
 
     NOW, THEREFORE, for the purposes set forth above and in consideration of
the mutual covenants contained herein, and intending to be legally bound hereby,
the parties agree as follows:
 
     1. AGREEMENT NOT TO COMPETE.
 
          (a) Dr. Green hereby acknowledges and recognizes the highly
     competitive nature of the Business Activities and accordingly agrees that
     Dr. Green will not, during and for a period of two (2) years commencing
     with the date hereof (the "Non-Competition Period"), directly or
     indirectly, (i) engage in any of the Business Activities, whether such
     engagement is as an officer, director, proprietor, employee, partner,
     investor (other than as a passive investor in less than five percent (5%)
     of the outstanding capital stock of a publicly traded corporation),
     consultant, advisor, agent, or other participant in another business,
     within the geographic territory in which the Buyer is conducting Business
     Activities or actively pursuing business in order to conduct Business
     Activities thereat (the "Restricted Territory"); (ii) assist other in
     engaging in any of the Business Activities in the manner described in the
     foregoing clause (i); (iii) solicit or induce any person who then is or was
     an employee of the Buyer to terminate his or her employment or offer
     employment to or hire or engage any such person; or (iv) solicit customers
     or prospective customers of the Buyer.
 
          (b) Notwithstanding the provisions of Section 1(a), Dr. Green shall be
     permitted to (i) accept employment with a pharmaceutical company including,
     in connection therewith, participate in or be responsible for the
     development and establishment of a clinical research network and/or a site
     management organization so long as Dr. Green does not, directly or
     indirectly, solicit members of the Sellers' clinical research network, the
     rights with respect to which have been assigned to Buyer under the
 
                                      A-52
<PAGE>   144
 
     Asset Purchase Agreement, and (ii) accept employment with any clinical
     research organization which succeeds to the business of DataTRAK, Inc.
     ("DataTRAK") so long as Dr. Green is only engaged in the DataTRAK business
     in connection therewith. A description of the DataTRAK business is attached
     hereto as Exhibit "A."
 
          (c) Notwithstanding the provisions of Section 1(a) hereof, nothing
     contained herein shall restrict Dr. Green from engaging, for and on behalf
     of the Sellers as an officer or employee thereof (as appropriate), in those
     activities which the Sellers are expressly permitted to engage in under the
     provisions of the last sentence of Section 1(a) of the Non-Competition
     Agreement executed on the date hereof by the Sellers and DataTRAK in favor
     of the Buyer (the provisions of which are incorporated herein by reference
     thereto).
 
     2. CONFIDENTIALITY. Dr. Green agrees to hold in a fiduciary capacity for
the benefit of the Buyer, all secret and confidential information, knowledge,
techniques of doing business, or data (including customer and prospect lists)
involving or related to the Clinical Business (as defined in the Asset Purchase
Agreement) ("Confidential Information") and will not, without Buyer's prior
written consent, at any time during or after the Non-Competition Period,
communicate or divulge any such Confidential Information, to any individual,
firm, partnership, corporation, or other entity nor shall Dr. Green, at any time
during or after the Non-Competition Period, make use of any Confidential
Information for Dr. Green's own purposes or for the benefit of any person or
other entity under any circumstances, except and to the extent (i) any of the
foregoing is in the public domain (other than as a result of Dr. Green's breach
of this Section 2), or (ii) such disclosure is required by law or appropriate
court order and written notice thereof is provided to the Buyer not less than
ten (10) days prior to such disclosure.
 
     3. REFORMATION. It is expressly understood and agreed that, although Dr.
Green and the Buyer consider the restrictions contained in Sections 1 and 2
hereof to be reasonable for the purpose of preserving for the Buyer the good
will, proprietary rights and going business value of the business and assets
acquired by the Buyer, if a final judicial determination is made by a court
having jurisdiction that the time or territory or any other restriction
contained in Sections 1 or 2 hereof is an unreasonable or otherwise
unenforceable restriction against Dr. Green, the provisions of Sections 1 or 2
hereof, as appropriate, shall not be rendered void, but shall be deemed amended
to apply as to such maximum time and territory and to such other extent as such
court may judicially determine or indicate to be reasonable.
 
     4. INJUNCTIVE RELIEF. Dr. Green acknowledges and agrees that the Buyer's
remedy at law for a breach or threatened breach of any of the provisions of
Sections 1 or 2 hereof would be inadequate and, in recognition of that fact, in
the event of a breach or threatened breach by Dr. Green of the provisions of
Sections 1 or 2 hereof, it is agreed that, in addition to its remedy at law, the
Buyer shall be entitled to, without posting any bond or other security,
equitable relief in the form of specific performance, temporary restraining
order, temporary or permanent injunction, or any other equitable remedy which
may then be available and Dr. Green agrees not to oppose the Buyer's request for
any of the above relief. Nothing herein contained shall be construed as
prohibiting the Buyer from pursuing any other rights and remedies available to
it for such breach or threatened breach.
 
     5. EXTENSION OF NON-COMPETITION PERIOD. The Non-Competition Period shall be
automatically extended for any period of time during which Dr. Green has
breached, or threatened to breach, any of the provisions hereof.
 
     6. WAIVERS. The waiver by the Buyer of a breach or threatened breach of any
provision of this Agreement by Dr. Green shall not operate or be construed as a
waiver of any subsequent breach or threatened breach by Dr. Green.
 
     7. ASSIGNMENT. This Agreement shall not be assignable by Dr. Green without
the prior written consent of the Buyer. The Buyer may, upon written notice to
but without the consent of Dr. Green, assign its rights hereunder to any party
including, without limitation, any successor of its business.
 
     8. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the domestic, internal laws (but not the law or conflict of
laws) of the Commonwealth of Pennsylvania.

     9. BINDING EFFECT. Subject to Section 7 hereof, the provisions of this
Agreement are for the benefit of the Buyer and may be enforced by the Buyer and
the Buyer's successors and assigns.
 
     IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
caused this Agreement to be executed the day and year first written above.

Attention: Mr. Michael Anderson
 
Dear Mr. Anderson:
 
     On December 21, 1998, The West Company, Incorporated ("Buyer"),
Collaborative Clinical Research, Inc. ("Collaborative"), GFI Pharmaceutical
Services, Inc. ("GFI"), and Collaborative Holdings, Inc. ("CHI") (Collaborative,
GFI and CHI being collectively referred to herein as the "Sellers") entered into
an Asset Purchase Agreement (the "Purchase Agreement"). Pursuant to the terms of
the Purchase Agreement, the Sellers agreed to sell and the Buyer agreed to
purchase substantially all of the assets of the Sellers relating to the Clinical
Business (as defined in the Purchase Agreement). DataTRAK, Inc. ("DataTRAK") is
engaged in, among other things, the business of developing and providing
software, technology and related electronic data handling services (as more
fully described on Exhibit "A" on the Non-Competition Agreement to be executed
by the Sellers and DataTRAK pursuant to the Purchase Agreement).
 
     In connection with the transactions described in the Purchase Agreement and
as a material inducement for the Buyer to complete such transactions, DataTRAK
covenants and agrees to make the services and the products of DataTRAK's
electronic data capture business available to the Buyer on royalty, fee and
other material terms which are no less favorable than those terms offered to
other non-affiliated customers (excluding, however, arrangements made by
DataTRAK with any members of any Consortium described in Section 1(c) of the
above mentioned Non-Competition Agreement.
 
     DataTRAK has executed this letter intending to be legally bound.
 
                                          DATATRAK, INC.
 
                                          By

The Board of Directors
Collaborative Clinical Research, Inc.
20600 Chagrin Boulevard, Suite 1050
Cleveland, Ohio 44122
 
Dear Members of the Board of Directors:
 
     You have requested our opinion as to the fairness, from a financial point
of view, of the consideration to be received by Collaborative Clinical Research,
Inc. pursuant to the terms and subject to the conditions set forth in the Asset
Purchase Agreement dated December 21, 1998 (the "Agreement") entered into by and
among Collaborative Clinical Research, Inc., an Ohio corporation, and its
subsidiaries GFI Pharmaceutical Services, Inc. and Collaborative Holdings, Inc.
(collectively "Collaborative") or the "Company") and The West Company,
Incorporated, a Pennsylvania corporation ("West"). As more fully described in
the Agreement, Collaborative will sell substantially all of its assets relating
to or used in its Clinical Business, as defined therein, and will receive from
West cash consideration of $15 million, subject to adjustment as provided
therein (the "Transaction").
 
     McDonald Investments Inc., A KeyCorp Company, as part of its investment
banking business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.
 
     In arriving at our opinion, we reviewed the Agreement and held discussions
with certain senior officers, directors and other representatives and advisors
of Collaborative, In addition, we reviewed historical financial statements of
Collaborative and certain financial forecasts and other data provided to us by
the management of Collaborative. We examined certain publicly available business
and financial information relating to the contract research organization
industry, including various investment reports by securities analysts who follow
the industry. We reviewed the financial terms of the Transaction in relation to,
among other things: current and historical market prices and trading volumes of
Collaborative Common Shares; historical and projected revenue and earnings of
Collaborative, backlog information; and the capitalization and financial
condition of Collaborative. We evaluated, to the extent publicly available, the
financial terms of certain other similar transactions recently effected which we
considered comparable to that set forth in the Agreement. We also analyzed
certain publicly available information with respect to certain other contract
research organizations that we believe to be comparable to Collaborative or the
Clinical Business and the trading markets for certain of such other companies'
securities. In addition to the foregoing, we conducted such other analyses and
 
                                       B-1
<PAGE>   160
 
examinations and considered such other financial, economic and market criteria
as we deemed appropriate in arriving at our opinion.
 
     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the financial and other information provided us or
publicly available and have assumed and relied upon the representations and
warranties made by Collaborative in the Agreement. We have not been engaged to,
and have not independently attempted to, verify such information. We have not
conducted an appraisal of the assets, properties, or facilities of Collaborative
or the Clinical Business, nor have we been furnished with any such appraisal. We
have not been asked to consider, and our opinion does not address, the relative
merits of the Transaction as compared to any alternative business strategy that
might exist for Collaborative or the Clinical Business.
 
     This opinion has been prepared for the use of the Board of Directors of
Collaborative in its evaluation of the Transaction. The opinion may be included
in a Proxy Statement (or other document given to the holders of Collaborative's
Common Shares) upon McDonald's review and written consent. The opinion does not
constitute a recommendation to any shareholder of Collaborative as to whether
such shareholder should vote in favor of ratifying the Agreement. Our opinion is
necessarily based upon information available to us, and financial, stock market
and other conditions and circumstances existing and disclosed to us, as of the
date hereof.
 
     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Consideration to be received by Collaborative pursuant to the
Agreement is fair, from a financial point of view, to the Company.
 
                                          Very truly yours,
 
                                          McDONALD INVESTMENTS INC.

                          OHIO REVISED CODE ANNOTATED
                    TITLE XVII. CORPORATIONS -- PARTNERSHIPS
                     CHAPTER 1701. GENERAL CORPORATION LAW
                            MERGER AND CONSOLIDATION
 
      1701.85 QUALIFICATIONS OF AND PROCEDURES FOR DISSENTING SHAREHOLDERS
 
     (A)(1) A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.
 
     (2) If the proposal must be submitted to the shareholders of the
corporation involved, the dissenting shareholder shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date fixed for
the determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the date
on which the vote on the proposal was taken at the meeting of the shareholders,
the dissenting shareholder shall deliver to the corporation a written demand for
payment to him of the fair cash value of the shares as to which he seeks relief,
which demand shall state his address, the number and class of such shares, and
the amount claimed by him as the fair cash value of the shares.
 
     (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised Code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of a
merger pursuant to section 1701.801 of the Revised Code shall be a record holder
of the shares of the corporation as to which he seeks relief as of the date on
which the agreement of merger was adopted by the directors of that corporation.
Within twenty days after he has been sent the notice provided in section 1701.80
or 1701.801 of the Revised Code, the dissenting shareholder shall deliver to the
corporation a written demand for payment with the same information as that
provided for in division (A)(2) of this section.
 
     (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.
 
     (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made. The corporation promptly shall return such endorsed certificates to
the dissenting shareholder. A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting shareholder
within twenty days after the lapse of the fifteen-day period, unless a court for
good cause shown otherwise directs. If shares represented by a certificate on
which such a legend has been endorsed are transferred, each new certificate
issued for them shall bear a similar legend, together with the name of the
original dissenting holder of such shares. Upon receiving a demand for payment
from a dissenting shareholder who is the record holder of uncertificated
securities, the corporation shall make an appropriate notation of the demand for
payment in its shareholder records. If uncertificated shares for which payment
has been demanded are to be transferred, any new certificate issued for the
shares shall bear the legend required for certificated securities as provided in
this paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.
 
                                       C-1
<PAGE>   162
 
     (B) Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final orders in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505 of the Revised
Code. If, during the pendency of any proceeding instituted under this section, a
suit or proceeding is or has been instituted to enjoin or otherwise to prevent
the carrying out of the action as to which the shareholder has dissented, the
proceeding instituted under this section shall be stayed until the final
determination of the other suit or proceeding. Unless any provision in division
(D) of this section is applicable, the fair cash value of the shares that is
agreed upon by the parties or fixed under this section shall be paid within
thirty days after the date of final determination of such value under this
division, the effective date of the amendment to the articles, or the
consummation of the other action involved, whichever occurs last. Upon the
occurrence of the last such event, payment shall be made immediately to a holder
of uncertificated securities entitled to such payment. In the case of holders of
shares represented by certificates, payment shall be made only upon and
simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.
 
     (C) If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and, in
the case of a merger pursuant to section 1701.80 or 1701.801 of the Revised
Code, fair cash value as to shareholders of a constituent subsidiary corporation
shall be determined as of the day before the adoption of the agreement of merger
by the directors of the particular subsidiary corporation. The fair cash value
of a share for the purposes of this section is the amount that a willing seller
who is under no compulsion to sell would be willing to accept and that a willing
buyer who is under no compulsion to purchase would be willing to pay, but in no
event shall the fair cash value of a share exceed the amount specified in the
demand of the particular shareholder. In computing such fair cash value, any
appreciation or depreciation in market value resulting from the proposal
submitted to the directors or to the shareholders shall be excluded.
 
     (D)(1) The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:
 
          (a) The dissenting shareholder has not complied with this section,
     unless the corporation by its directors waives such failure;
 
                                       C-2
<PAGE>   163
 
          (b) The corporation abandons the action involved or is finally
     enjoined or prevented from carrying it out, or the shareholders rescind
     their adoption of the action involved;
 
          (c) The dissenting shareholder withdraws his demand, with the consent
     of the corporation by its directors;
 
          (d) The corporation and the dissenting shareholder have not come to an
     agreement as to the fair cash value per share, and neither the shareholder
     nor the corporation has filed or joined in a complaint under division (B)
     of this section within the period provided in that division.
 
     (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.
 
     (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair cash
value of the shares. If the right to receive fair cash value is terminated other
than by the purchase of the shares by the corporation, all rights of the holder
shall be restored and all distributions which, except for the suspension, would
have been made shall be made to the holder of record of the shares at the time
of termination.

     such written agreement shall be a condition to the receipt of such option."
