                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
ClinTrials Research Inc.
 
     We have audited the accompanying balance sheets of Bio-Research
Laboratories Ltd. as of December 31, 1995 and 1994, and the related statements
of income, stockholders' equity, and cash flows for each of the three years in
the period ended December 31, 1995. 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 financial statements referred to above present fairly,
in all material respects, the financial position of Bio-Research Laboratories
Ltd. at December 31, 1995 and 1994, and the results of operations and cash flows
for each of the three years in the period ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1.  ORGANIZATION
 
     Bio-Research Laboratories Ltd. ("Bio-Research"), located in Montreal,
Quebec, Canada, is an independent contract research laboratory providing
preclinical research services to clients in the pharmaceutical, biotechnology,
chemical and medical device industries, primarily serving the United States, the
Far East, Europe and Canada.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
TRANSLATION OF FINANCIAL STATEMENTS INTO U.S. DOLLARS
 
     The functional currency of Bio-Research is Canadian dollars. Assets and
liabilities amounts of Bio-Research are translated into U.S. dollars at the
year-end rate of exchange, and the income statements amounts are translated at
the average rates of exchange for the period. Gains or losses from translating
financial statements are accumulated in a separate component of stockholders'
equity.
 
     Bio-Research enters into forward exchange contracts with banks to hedge
foreign currency transactions, and not to engage in currency speculation. Gains
and losses on forward exchange contracts to hedge future transactions are
deferred and accounted for as part of the cost of these transactions.
 
CASH AND CASH EQUIVALENTS
 
     For the purpose of the statement of cash flows, cash and cash equivalents
include demand deposits and money market accounts held with a financial
institution. Bio-Research considers all highly liquid investments with a
maturity of three months or less when purchased to be cash equivalents.
 
REVENUE RECOGNITION
 
     Revenue from contracts is recorded as costs are incurred and includes
estimated earned fees or profits calculated on the basis of the relationship
between costs incurred and total estimated costs (cost-to-cost type of
percentage-of-completion method of accounting). Certain contracts contain
provisions for price redetermination for cost overruns. Such redetermined
amounts are included in service revenue when realization is assured and the
amounts can reasonably be determined. Estimated amounts representing contract
change orders, claims or funding limitations are included in service revenue
only when realization is probable. In the period in which it is determined that
a loss will result from the performance of a contract, the entire amount of the
estimated ultimate loss is charged against income. Other changes in estimates of
service revenue, costs and profits are recognized using the cumulative catch-up
method of accounting. This method recognizes in the current period the
cumulative effect of the changes on current and prior periods. Hence, the effect
of the changes on future periods of contract performance is recognized as if the
revised estimates had been the original estimates.
 
UNBILLED RECEIVABLES AND ADVANCE BILLINGS
 
     Unbilled receivables arise from those contracts under which billings can
only be rendered upon the achievement of certain negotiated performance
requirements or on a date-certain basis. Advance billings represent contractual
prebillings for services not yet rendered.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost.
 
     Depreciation is provided on the straight-line method over the estimated
useful lives of the respective properties, which approximate three to forty
years.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
NEWLY ISSUED ACCOUNTING STANDARDS
 
     Bio-Research has considered the impact of newly issued financial accounting
pronouncements, principally Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," and does not believe that adoption of this and any other newly
issued pronouncements would have a significant impact on Bio-Research's
financial statements.

     At December 31, 1995, Bio-Research had unrealized research and development
tax credits, net of income tax effect, of $10,036. These credits expire in years
1997 through 2005. For financial reporting purposes, a valuation allowance of
$6,758 has been recognized to offset the deferred tax assets related to those
carryforwards. The net deferred tax asset reflects a decrease in the valuation
allowance of approximately $110.

10.  MAJOR CLIENTS
 
     For the year ended December 31, 1993, one client accounted for 12% of
Bio-Research's service revenue. No single client accounted for more than 10% of
Bio-Research's service revenue for the year ended 1994 or 1995.
 
11.  COMMITMENTS AND CONTINGENCIES
 
     During 1995, Bio-Research entered into foreign exchange contracts to
deliver United States currency for the purpose of hedging its United States
currency cash flow. These contracts call for the delivery of $750,000 United
States Dollars per month for the period January 1996 through January 1997 at
exchange rates averaging $1.3821 Canadian Dollar per United States Dollar.
 
     During 1993, Bio-Research undertook a project to upgrade its computer
systems, which it expects to implement in phases through 1997 at a cost of
approximately $4.8 million. Approximately $2.6 million of this amount was
incurred as of December 31, 1995.
 
     In 1991, a customer commenced legal action against Bio-Research claiming
damages in the amount of $5.2 million, plus interest and costs, resulting from
statistical errors in carrying out two clinical research studies. An amount of
$220,000 has been provided for in the accounts with respect to this claim. Based
on applicable insurance coverage and an indemnification agreement from a former
stockholder in favor of Bio-Research in respect of any liability in excess of
the amount provided for, management is of the opinion that the outcome of this
matter will not have any further impact upon the financial position of
Bio-Research.
 
     Also, in the ordinary course of business, Bio-Research is involved in
certain claims and litigation. Management is of the opinion, based on
information presently available to it, that the eventual outcome of these
matters will not have a material adverse effect upon the financial position of
Bio-Research.
 
12.  SUBSEQUENT EVENT
 
     On May 24, 1996, Bio-Research announced the signing of a definitive
agreement to sell the assets of Bio-Research to ClinTrials Research Inc., a
Nashville, Tennessee based clinical research organization, for approximately $65
million plus the assumption of certain liabilities.

                          NOTES TO UNAUDITED PRO FORMA
 
                        CONDENSED COMBINED BALANCE SHEET
 
(1) To record the purchase of the net assets (including the recording of excess
     of purchase price over net assets acquired) and eliminate the stockholders'
     equity of Bio-Research. No estimate of any purchase accounting adjustments
     to record property and equipment at fair value has been made at this time.
     ClinTrials expects to obtain and record a valuation of Bio-Research's
     property and equipment within six months following the Acquisition. It is
     not expected that the reclassification between excess of purchase price
     over net assets acquired and property and equipment will be significant to
     the combined balance sheet. The pro forma adjustments reflect a temporary
     payable to the stockholders of Bio-Research to effect the purchase of
     Bio-Research. The temporary payable would be satisfied from the proceeds of
     the offering referred to in pro forma adjustment (2).
 
(2) To record the net proceeds from the completion of the offering of 2,600,000
     shares of ClinTrials Common Stock at an assumed price of $42.00 per share.
     Gross proceeds of $109.2 million, less estimated issuance costs of $6.1
     million, provides net proceeds of $103.1 million. A portion of the net
     proceeds would be utilized to retire the temporary payable to the
     stockholders of Bio-Research referred to in pro forma adjustment (1).

                          NOTES TO UNAUDITED PRO FORMA
 
                    CONDENSED COMBINED STATEMENTS OF INCOME
 
(1) The pro forma condensed combined statements of income do not give effect to
     any overhead reductions or cost savings, if any, which may be realized
     after the consummation of the Acquisition.
 
(2) To adjust amortization expense. The excess of purchase price over net assets
     acquired related to the Acquisition will be amortized over 40 years using
     the straight line method. The amounts for the year ended December 31, 1995
     and the three months ended March 31, 1996 were $959 and $240, respectively.
     No estimate of any purchase accounting adjustments to record property and
     equipment at fair value has been made at this time. ClinTrials expects to
     obtain and record a valuation of Bio-Research's property and equipment
     within six months following the Acquisition. It is not expected that any
     reclassification between excess of purchase price over net assets acquired
     and property and equipment would significantly affect amortization expense.
 
(3) Interest income as a result of the cash proceeds received in excess of the
     cash used to acquire Bio-Research and for costs of the Offering is not
     reflected in the pro forma condensed combined statements of income. The
     Company is presently earning a 4.11% yield on tax exempt investments. The
     following table summarizes the total effect on the pro forma condensed
     combined statements of income as if the interest had been earned on the
     excess cash.

(4) The pro forma amortization adjustment (Note 2) does not affect the income
     tax provision as such tax benefit of the amortization adjustment would
     merely increase the federal and Quebec research and development tax credits
     to be carried forward to future periods. The pro forma condensed combined
     statements of income do not provide for deferred United States taxes on the
     income earned by Bio-Research in Canada as ClinTrials intends to
