                                     PART I

                                     ITEM 1.

                                    BUSINESS
                                    --------

    Kendle International Inc., an Ohio corporation established in 1989, (the
"Company"), is a contract research organization (CRO) that provides a broad
range of Phase I through IV clinical research and drug development services to
the pharmaceutical and biotechnology industries. The Company augments the
research and development activities of pharmaceutical and biotechnology
companies by offering high quality, value added clinical research services and
proprietary information technology designed to reduce drug development time and
expense. The Company is organized into two segments for financial reporting
purposes. The contract research services group conducts clinical trial
management, clinical data management, statistical analysis, medical writing, and
regulatory consulting and representation. The medical communications group,
Healthcare Communications Inc. (HCC), a wholly-owned subsidiary of the Company,
provides organizational, meeting management, and publication services to
professional associations and pharmaceutical companies.


         The Company believes that the outsourcing of drug development
activities by pharmaceutical and biotechnology companies has been increasing and
will continue to increase as these companies strive to increase revenues through
faster drug development while also dealing with cost containment pressures. The
CRO industry, by specializing in clinical trial management, is often able to
perform the needed services with a higher level of expertise or specialization,
more quickly and at a lower cost than a customer could perform the services
internally.

         The Company's strategy is to continue to enhance its reputation as a
high-quality provider of a full range of CRO services. The Company's strategy
consists of the following key elements: (i) continue to expand its broad range
of therapeutic expertise; (ii) offer its customers "one-stop shopping" with a
full range of services that encompass the clinical research process and
complement the research and development departments of its customers; (iii)
expedite the drug development process through innovative information technology
offered via the Company's proprietary TrialWare(R) software including
TrialWeb(TM), its clinical trial information web service; (iv) continue to build
a brand presence that portrays high quality work; and (v) supplement internal
growth through strategic acquisitions that expand the Company's geographic
presence and add to the Company's clinical development capabilities in existing
or new therapeutic areas or service offerings.

         In January, 1999, the Company acquired Research Consultants
(International) Holdings Limited ("IRC"), a U.K. based regulatory affairs
company for approximately $4.4 million in cash and 87,558 shares of the
Company's Common Stock.

         In June, 1999, the Company acquired ESCLI S.A., a CRO located in Paris,
France, for approximately $2.7 million in cash.

         In July, 1999, the Company acquired Health Care Communications Inc.
(HCC), a New Jersey based medical communications company, and HCC Health Care
Communications (1991), a Toronto based CRO, for approximately $5.7 million in
cash and 174,559 shares of the Company's Common Stock.

         In August, 1999, the Company acquired Specialist Monitoring Services
Limited (SMS), a U.K. based CRO, for approximately $7.5 million in cash and
141,680 shares of the Company's Common Stock.


                                       3
<PAGE>   4

         Additionally, in January, 1999, the Company acquired a minority
interest in Digineer, Inc. ("Digineer", formerly Component Software
International, Inc.), an Internet healthcare consulting and development company
for approximately $1.6 million in cash and 19,995 shares of the Company's Common
Stock. Additionally, the Company entered into a Multi-Year Strategic Service
Agreement with Digineer whereby the Company will pay Digineer $7.0 million over
a four year period in exchange for strategic software consulting and development
services.

         The Company's net revenues from G.D. Searle & Co. accounted for 24%,
38%, and 54%, of the Company's total net revenues for the years ended December
31, 1999, 1998, and 1997, respectively. Revenues from Centocor, Inc. accounted
for approximately 18% of net revenues for the year ended December 31, 1999 and
were less than 10% in 1998 and 1997.

         Segment and geographic information of the Company is contained in Note
16 to the consolidated financial statements on page 43 of the Company's Annual
Report to Shareholders for 1999, and is incorporated herein by reference.

Backlog
- -------

         Backlog is based on signed contracts and letters of intent. Backlog at
December 31, 1999 was $128 million compared to $96 million at December 31, 1998.
No assurance can be given that the Company will be able to realize the net
revenues that are included in the backlog. Backlog is not necessarily a
meaningful indicator of future results for a variety of reasons, including, but
not limited to, the following: (i) contracts vary in size and duration, with
revenue from some studies realized over a number of years; (ii) the scope of
contracts may change, either increasing or decreasing the value of the contract;
and (iii) studies may be terminated or delayed by the sponsor or by regulatory
authorities.


Competition
- -----------

         The Company competes primarily against in-house research and
development departments of pharmaceutical and biotechnology companies,
universities, teaching hospitals and other full-service CROs, some which possess
substantially greater capital, technical and other resources than the Company.
CROs generally compete on the basis of previous experience, medical and
scientific expertise in specific therapeutic areas, the quality of services
provided, the ability to manage large-scale trials on a global basis, medical
database management capabilities, the ability to provide statistical and
regulatory services, the ability to recruit investigators, the ability to
recruit patients into studies, the ability to integrate information technology
with systems to improve the efficiency of contract research, an international
presence with strategically located facilities, financial viability and price.

         The CRO industry is highly fragmented with several hundred CROs ranging
from small, limited-service providers to full-service, global drug development
corporations. The Company competes with the following CROs, among others:
ClinTrials Research Inc., Covance, Inc., PAREXEL International Corporation,
Pharmaceutical Product Development, Inc. and Quintiles Transnational
Corporation.


Employees
- ---------

         As of February 29, 2000, the Company had approximately 1,525 employees.
None of the Company's employees are covered by a collective bargaining
agreement.

                                     ITEM 2.

                                   PROPERTIES
                                   ----------

         The Company leases all of its facilities with the exception of the
Company-owned facility in Ely, United Kingdom. The Company's principal executive
offices are located in Cincinnati, Ohio, where it leases approximately 118,000
square feet under a lease expiring in 2006. The Company also maintains offices
in various other U.S. locations and in Europe and the Pacific Rim.

         Management believes that such offices are sufficient to meet its
present needs and does not anticipate any difficulty in securing additional
space, as needed, on terms acceptable to the Company.


                                     ITEM 3.

                                LEGAL PROCEEDINGS
                                -----------------

         The Company currently is not involved in any material litigation, nor,
to the Company's knowledge, is any material litigation currently threatened
against the Company.


                                     ITEM 4.

               SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
               ---------------------------------------------------

         No matters were submitted to a vote of security holders during the
fourth quarter of 1999.

                     EQUITY AND RELATED SHAREHOLDER MATTERS
                     --------------------------------------

         "Quarterly Financial Data" on page 21 and "Transfer Agent and Registrar
and Stock Information" on page 45 of the Company's Annual Report to Shareholders
for 1999 are incorporated herein by reference. The Company has not paid

The Company does not currently intend to pay dividends in the foreseeable
future, but intends instead to reinvest earnings in its business.

                           Canadian Seller and Geoffrey H. Kalish, M.D. entered
                           into an Asset Purchase Agreement (the "Canadian
                           Purchase Agreement"). Pursuant to the terms of said
                           Canadian Purchase Agreement, Canadian Purchaser is
                           today



                                       1

                           purchasing from the Canadian Seller substantially all
                           of the assets of the Canadian Seller.

                  C.       The parties desire to enter into this Escrow
                  Agreement to provide for an escrow of certain cash and stock
                  (the "Escrow Property") to provide financial support for
                  Sellers' obligation to indemnify the Purchasing Group for any
                  breaches of warranty or representation by the Selling Group
                  under the U.S. Purchase Agreement and the Canadian Purchase
                  Agreement.

                  NOW, THEREFORE, in consideration of the mutual covenants set
forth below and other good and valuable consideration, the parties hereto agree
as follows:

                  1. DESIGNATION AND DELIVERY. The Purchasing Group and the
Selling Group hereby designate The Fifth Third Bank as "Escrow Agent" under this
Escrow Agreement. The Purchasing Group and the Selling Group hereby deliver to
the Escrow Agent a copy of the U.S. Purchase Agreement and the Canadian Purchase
Agreement, which documents are attached hereto and incorporated herein as
Exhibit "A" and "A-1." The Purchasing Group, in accordance with the U.S.
Purchase Agreement and the Canadian Purchase Agreement, hereby delivers to the
Escrow Agent, and the Escrow Agent hereby acknowledges receipt of, cash in the
amount of $500,000 (the "Deposit") and 31,943 shares of the common stock, no par
value, of Kendle (the "Stock").

                  2. INVESTMENT OF THE DEPOSIT; DIVIDENDS AND DISTRIBUTIONS WITH
RESPECT TO THE DEPOSIT AND STOCK.

                           (a) The Escrow Agent is hereby authorized to invest
the Deposit in money market funds, including the Fountain Square U.S. Treasury
Obligations Fund sponsored by the Escrow Agent's affiliate, Fountain Square
Funds. The Escrow Agent shall cause all stock dividends and stock distributions
(including shares distributed in a stock split) earned on or with respect to the
Stock to be added to the Escrow Property. The U.S. Seller shall be entitled to
exercise all voting rights with respect to any Stock or other Kendle securities
held from time to time as part of the Escrow Property until such time as, if at
all, any such securities are distributed to Kendle in accordance with Section 5
hereof. The parties further acknowledge that the amount of cash and securities
held as part of the Escrow Property may be reduced or (in the case of securities
only) increased from time to time during the term hereof pursuant to the terms
of this Escrow Agreement. Accordingly, the term "Escrow Property" shall refer to
the sum of (i) the Deposit initially placed in escrow hereunder or to such
lesser amount of cash as may be held in escrow pursuant hereto at any point
during the term hereof and (ii) the Stock initially placed into escrow hereunder
or such lesser or greater number of securities as may be held in escrow pursuant
hereto at any point during the term hereof. The parties agree that interest
earned on, and any other



                                       2
<PAGE>   3

accretions to, the Escrow Property (other than stock dividends and other stock
distributions) (collectively, "Seller's Accretions") shall not be deemed to be a
part of the Escrow Property and shall be treated in accordance with Section 2(b)
hereof.

                           (b) All Seller's Accretions earned on or distributed
with respect to the Escrow Property shall be the property of, and fully taxable
to, the U.S. Seller. On each date on which any portion of the Escrow Property is
released to the U.S. Seller pursuant to this Escrow Agreement (and, in any
event, on the date of the final release of the Escrow Property hereunder), the
Escrow Agent shall pay to the U.S. Seller, all Seller's Accretions which have
accrued on or been received with respect to the Escrow Property through such
date.

                           (c) The parties acknowledge that, based upon the
Market Value of Kendle common stock as of the Closing Date, 50% of the initial
Escrow Property consists of the Stock and 50% of the initial Escrow Property
consists of cash.

                  3. ESCROW AGENT AS CUSTODIAN; EXPENSES. The Escrow Agent
shall, for all purposes of this Escrow Agreement, be treated as and considered
legally a custodian. The Escrow Agent shall be entitled to rely conclusively
upon the written notice provided in Section 5 and may assume the genuineness of
all signatures and documents and the authority of all signatories. The Escrow
Agent shall have no liability except for gross negligence or willful misconduct
in the performance of its duties under this Escrow Agreement. Kendle and the
Selling Group, collectively, shall each assume and pay one half (1/2) of all
costs and expenses of the Escrow Agent incurred in its capacity as the Escrow
Agent under this Escrow Agreement. The fees of the Escrow Agent are set forth on
Exhibit "B" attached hereto and incorporated herein.

                  4.       RESIGNATION; DISAGREEMENTS.

                           (a) Escrow Agent (and any successor Escrow Agent) may
at any time resign as such by delivering the Escrow Property to any successor
Escrow Agent designated by the other parties hereto in writing, or to any court
of competent jurisdiction as provided below. The resignation of Escrow Agent
will take effect on the earlier of (i) the appointment of a successor (including
a court of competent jurisdiction), or (ii) the day which is thirty (30) days
after the date of delivery of its written notice of resignation to the other
parties hereto. If at that time Escrow Agent has not received a designation of a
successor Escrow Agent, Escrow Agent's sole responsibility after that time shall
be to retain and safeguard the Escrow Property until receipt of a designation of
successor Escrow Agent or a joint written disposition instruction by the other
parties hereto or a final order of a court of competent jurisdiction.



                                       3
<PAGE>   4

                           (b) In the event of any disagreement between the
other parties hereto resulting in adverse claims or demands being made in
connection with the Escrow Property or in the event that Escrow Agent is in
doubt as to what action it should take hereunder, Escrow Agent shall be entitled
to retain the Escrow Property until Escrow Agent shall have received (i) a final
order of a court of competent jurisdiction directing delivery of the Escrow
Property, or (ii) a written agreement executed by the other parties hereto
directing delivery of the Escrow Property, in which event Escrow Agent shall
disburse the Escrow Property in accordance with such order or agreement. Escrow
Agent shall act on such court order without further question.

                  5.       TERMINATION AND DISTRIBUTION OF ESCROW.

                           (a) TERMINATION. This Escrow Agreement shall
terminate on the date upon which the Escrow Agent shall have fully distributed
the Escrow Property as provided herein.

                           (b) CLAIM NOTICES. If, at any time on or prior to the
date falling two (2) years after the date hereof (the "Second Anniversary
Date"), the Escrow Agent shall receive a notice from any of the Purchasing Group
which (i) affirms that the Purchasing Group believes that the members of the
Selling Group are liable to the U.S. or Canadian Purchaser under the U.S.
Purchase Agreement or the Canadian Purchase Agreement, as the case may be, for
breaches of representations or warranties and (ii) states a specific amount (the
"Claimed Amount") which, as a result of the factual basis underlying such
notice, the Purchasing Group, in good faith, believes it is owed, by the Selling
Group (any such notice being herein referred to as a "Claim Notice"), the Escrow
Agent shall continue to hold in escrow the Claimed Amount stated in such notice
until (A) it shall receive further instructions as to the disposition of such
sum in a writing signed by Kendle and either of the Sellers or (B) it shall be
otherwise ordered by a court of competent jurisdiction. The parties acknowledge
that there may be multiple Claim Notices given by the Purchasing Group during
the term hereof. The Escrow Agent shall deliver a copy of each Claim Notice
received by it to the appropriate Seller.

                           (c) PARTIAL RELEASE. Within 15 days after the date
falling one year after the date hereof (the "First Anniversary Date"), the
Escrow Agent shall release to the U.S. Seller, an amount equal to the excess, if
any, of (i) the Escrow Property as of the First Anniversary Date over (ii) the
sum of (A) $500,000 and (B) any portions of the Escrow Property required, as of
the First Anniversary Date, to be held in escrow pursuant to Section 2(b).

                           (d) FINAL RELEASE. Within 15 days after the Second
Anniversary Date, the Escrow Agent shall release to the U.S. Seller an amount
equal to the excess, if any, of the Escrow Property as of the Second Anniversary



                                       4
<PAGE>   5

Date over the aggregate sum required as of the Second Anniversary Date to be
held in escrow pursuant to Section 5(b).

                           (e) JOINT WRITTEN DIRECTION. Notwithstanding any
provision in this Section 5 to the contrary, the Escrow Agent may make payments
from the Escrow Property, or from any Seller's Accretions, at any time upon
receipt of a joint written direction from Kendle and either of the Sellers (a
"Joint Written Direction").

                           (f) NO DISPUTE. If, on or prior to the Second
Anniversary Date, Kendle shall have delivered a Notice of Claim to the Escrow
Agent and appropriate Seller and such Seller shall not have disputed the Notice
of Claim within ten (10) business days after their receipt of the Notice of
Claim, the Claim Amount shall promptly be released to Kendle by the Escrow
Agent.

                           (g) VALUATION; ALLOCATIONS. For purposes of
determining that portion of the Escrow Property which is to be withheld or
released, as the case may be, under this Section 5 (and except as may be
otherwise provided in a Joint Written Direction), the Market Value of the Stock
shall be used, except that the relevant date used for counting back 20 trading
days shall be (i) the date on which a Claim Notice shall have been given to the
Escrow Agent, (ii) the First Anniversary Date or (iii) the Second Anniversary
Date, as the case may be. In addition, to the extent that any withholding or
release of the Escrow Property by the Escrow Agent is to be effectuated
hereunder, such withholding or release shall be comprised of Stock and cash in
the same percentages referred to in Section 2(c) hereof.

                  6. DUTIES OF ESCROW AGENT. The duties of the Escrow Agent
under this Escrow Agreement shall be entirely administrative and the Escrow
Agent shall not be liable to any third party as a result of any action or
omission taken or made by it, if taken in good faith, except for gross
negligence or willful misconduct in performing its duties. In the event of
disagreement or dispute between Kendle and the Selling Group with respect to
disposition of the Escrow Property, the Escrow Agent shall have the right to
initiate an appropriate legal proceeding to obtain a judicial determination of
the respective parties' rights to the Escrow Property. No rights are intended to
be granted to any third party hereunder. Kendle and the Selling Group shall
severally (each being responsible for a maximum of fifty percent (50%) of the
indemnity account) indemnify and hold harmless the Escrow Agent and reimburse
the Escrow Agent from and for any and all liability, costs and expenses,
including reasonable attorneys' fees, the Escrow Agent may suffer or incur by
reason of its execution and performance of this Escrow Agreement except for any
such liability, costs or expenses (including attorneys fees) which is a result
of Escrow Agent's own gross negligence or willful misconduct. The Escrow Agent
shall have no duties except those which are expressly set forth herein, and it
shall not be bound by any notice of a claim,



                                       5
<PAGE>   6

or demand with respect thereto, or any waiver, modification, amendment,
termination or recission of this Escrow Agreement, unless in writing received by
it and signed by Kendle and either Seller.

                  In the event that the Escrow Agent shall find it necessary to
consult with counsel of its own choosing in connection with this Escrow
Agreement, the Escrow Agent shall not incur any liability for any action taken
in good faith in accordance with such advice. Kendle and the Selling Group,
jointly and severally, shall indemnify and hold harmless the Escrow Agent for
any liability, loss, claim or damage incurred by the Escrow Agent in connection
with this Escrow except for any such liability, costs, expenses (including
reasonable attorneys' fees), loss, claims or damage which is a result of Escrow
Agent's own gross negligence or willful misconduct. This indemnification shall
survive termination of this Escrow Agreement. Kendle and the Selling Group agree
that Kendle, on the one hand, and the Selling Group, collectively, on the other
hand, shall each assume and pay fifty percent (50%) of all amounts due to Escrow
Agent as a result of this indemnification.

                  Escrow Agent is not a party to, and is not bound by, any
agreement which may be evidenced by, or arise out, the foregoing instruction,
other than as expressly set forth herein. In the event that any of the terms and
provisions of any other agreement (excluding any amendment to this Escrow
Agreement) between any of the parties hereto, conflict or are inconsistent with
any of the provisions of this Escrow Agreement, the terms and provisions of this
Escrow Agreement shall govern and control in all respects.

                  7. NOTICES. All notices, consents or other communications
required or permitted to be given under this Escrow Agreement shall be in
writing and shall be deemed to have been duly given:

                           (a) when delivered personally (including via
recognized courier service, such as Fed Ex)

                           (b) five (5) business day after being sent by
certified U.S. mail, postage charges prepaid, or

                           (c) on the date on which a telegram or facsimile is
transmitted to the parties at their respective addresses stated above.

                  Any party may change its address for notice and the address to
which copies must be sent by giving notice of the new addresses to the other
parties in accordance with this Section 7, except that any such change of
address notice shall not be effective unless and until received.



                                       6
<PAGE>   7

                  8. AMENDMENT. No amendment or modification of this Escrow
Agreement shall be effective unless in writing and signed by the parties.

                  9.       SUPPLEMENTAL ESCROW AGREEMENT.

                           (a) The parties acknowledge that, pursuant to Section
11(b)(v) of the U.S. Purchase Agreement, in the event, and to the extent, that
any given claim or claims being asserted in good faith by the Purchaser could
not be satisfied out of the assets being held under this Agreement, Purchaser
may seek recourse by depositing earned, but not yet paid, Earnout Amounts with
the Escrow Agent under this Agreement. The parties have now agreed, however,
that any such sums should, contrary to the U.S. Purchase Agreement, be deposited
with the Escrow Agent not under this Agreement but rather under a similar Escrow
Agreement attached hereto as Exhibit C (the "Secondary Escrow Agreement").
Consequently, in the event of any such deposit by the Purchasing Group (which
deposit must be accompanied by a Claim Notice under the Secondary Escrow
Agreement alleging a Claimed Amount at least equal in amount to the amount being
deposited), the attached Secondary Escrow Agreement shall be deemed
automatically, on the date of the first such deposit (regardless whether the
same shall occur prior to or after the termination of this Agreement), to have
been executed and delivered by the parties hereto, and any sums then or
thereafter deposited pursuant to the aforesaid Section 11(b)(v) shall be deemed
to have been deposited thereunder.

                           (b) The Purchasing Group agrees that any Earnout
Amounts that are deposited with the Escrow Agent in accordance with Section 9(a)
above shall be allocated between cash and Kendle shares in the same percentages
referred to in Section 2(c) above; provided, however, that in the event that
(due to the fact that Earnout Amounts will be composed 67% of cash and 33 % of
Kendle shares) any given Earnout Amount shall not contain a sufficient number of
Kendle shares to comply with the preceding clause of this sentence, Kendle
shall, to the extent of any such deficiency, have the right to deposit with the
Escrow Agent cash instead of Kendle shares. The parties further agree that for
purposes of (i) determining the aggregate number of shares of Kendle stock
which, based upon the related Claim Notice, may be withheld from the U.S. Seller
and deposited in escrow under the Secondary Escrow Agreement and (ii)
implementing the terms of the preceding sentence, all Kendle shares shall be
valued at Market Value, using the 20 trading days preceding [the date on which
the EBIT for the then most recent fiscal year of the U.S. Purchaser shall have
been finally determined under Section 2.2 of the U.S. Purchase Agreement]

                           (c) The terms of this Section 9 shall survive
termination of this Agreement.

                  10. PARTIES IN INTEREST. This Escrow Agreement shall bind,
benefit, and be enforceable by and against each party hereto and their
successors, assigns, heirs and personal representatives. No party shall in any
manner assign any of its rights or obligations under this Escrow Agreement
without the express prior written consent of the other parties.

                  11. NO WAIVERS. No waiver with respect to this Escrow
Agreement shall be enforceable unless in writing and signed by the party against
whom enforcement is sought. Except as otherwise expressly provided herein, no
failure to exercise, delay in exercising, or single or partial exercise of any
right, power or remedy by any party, and no course of dealing between or among
any of the parties, shall constitute a waiver of, or shall preclude any other or
further exercise of the same or any other right, power or remedy.

                  12. SEVERABILITY. If any provision of this Escrow Agreement is
construed to be invalid, illegal or unenforceable, then the remaining provisions
hereof shall not be affected thereby and shall be enforceable without regard
thereto.

                  13. COUNTERPARTS. This Escrow Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall
constitute an original hereof, and it shall not be necessary in making proof of
this Escrow Agreement to produce or account for more than one original
counterpart hereof.

                  14. CONTROLLING LAW. This Escrow Agreement is made under, and
shall be construed and enforced in accordance with, the laws of the State of
Ohio applicable to agreements made and to be performed solely therein, without
giving effect to principles of conflicts of law.

                  15. DEFINITIONS. To the extent not specifically defined
herein, all terms used herein shall have the meanings ascribed to them in the
U.S. Purchase Agreement.

                  Purchase Agreement, Canadian Purchaser purchased from the
                  Canadian Seller substantially all of the assets of the
                  Canadian Seller.

                  C. The parties have previously agreed to enter into this
Escrow Agreement to provide for an escrow of certain cash and stock (the "Escrow
Property") to provide financial support for Sellers' obligation to indemnify the
Purchasing Group for any breaches of warranty or representation by the Selling
Group under the U.S. Purchase Agreement and the Canadian Purchase Agreement.

                  D. The agreement providing for the creation of this Agreement
was the Escrow Agreement, dated the Closing Date, entered into by the parties
hereto in connection with the U.S. and Canadian Purchase Agreements (the
"Primary Escrow Agreement").

                  NOW, THEREFORE, in consideration of the mutual covenants set
forth below and other good and valuable consideration, the parties hereto agree
as follows:

                  1. DESIGNATION AND DELIVERY. The Purchasing Group and the
Selling Group hereby designate The Fifth Third Bank as "Escrow Agent" under this
Escrow Agreement. The Purchasing Group and the Selling Group have previously
delivered to the Escrow Agent a copy of the U.S. Purchase Agreement and the
Canadian Purchase Agreement, which documents are incorporated herein by
reference. The Purchasing Group, in accordance with the U.S. Purchase Agreement,
the Canadian Purchase Agreement, and the Primary Escrow Agreement, hereby
delivers to the Escrow Agent, and the Escrow Agent hereby acknowledges receipt
of, certain cash (the "Deposit") and shares of the common stock, no par value,
of Kendle (the "Stock"). The Escrow Agent shall, promptly after its receipt of
the Deposit and the Stock (the date of occurrence of which shall be deemed for
all purposes to be the "Effective Date" of this Agreement), confirm to the U.S.
Seller the amount of the Deposit and the number of Kendle shares constituting
the Stock.

                  2. INVESTMENT OF THE DEPOSIT; DIVIDENDS AND DISTRIBUTIONS WITH
RESPECT TO THE DEPOSIT AND STOCK.


                           (a) The Escrow Agent is hereby authorized to invest
the Deposit in money market funds, including the Fountain Square U.S. Treasury
Obligations Fund sponsored by the Escrow Agent's affiliate, Fountain Square
Funds. The Escrow Agent shall cause all stock dividends and stock distributions
(including shares distributed in a stock split) earned on or with respect to the
Stock to be added to the Escrow Property. The U.S. Seller shall be entitled to
exercise all voting rights with respect to any Stock or other Kendle securities
held



                                       14
<PAGE>   15

from time to time as part of the Escrow Property until such time as, if at all,
any such securities are distributed to Kendle in accordance with Section 5
hereof. The parties further acknowledge that the amount of cash and securities
held as part of the Escrow Property may be reduced or increased from time to
time during the term hereof pursuant to the terms of this Escrow Agreement and
the U.S. Purchase Agreement. Accordingly, the term "Escrow Property" shall refer
to the sum of (i) the Deposit initially placed in escrow hereunder or to such
greater or lesser amount of cash as may be held in escrow pursuant hereto at any
point during the term hereof and (ii) the Stock initially placed into escrow
hereunder or such lesser or greater number of securities as may be held in
escrow pursuant hereto at any point during the term hereof. The parties agree
that interest earned on, and any other accretions to, the Escrow Property (other
than stock dividends and other stock distributions) (collectively, "Seller's
Accretions") shall not be deemed to be a part of the Escrow Property and shall
be treated in accordance with Section 2(b) hereof.

                           (b) All Seller's Accretions earned on or distributed
with respect to the Escrow Property shall be the property of, and fully taxable
to, the U.S. Seller. On each date on which any portion of the Escrow Property is
released to the U.S. Seller pursuant to this Escrow Agreement (and, in any
event, on the date of the final release of the Escrow Property hereunder), the
Escrow Agent shall pay to the U.S. Seller, all Seller's Accretions which have
accrued on or been received with respect to the Escrow Property through such
date.

                  3. ESCROW AGENT AS CUSTODIAN; EXPENSES. The Escrow Agent
shall, for all purposes of this Escrow Agreement, be treated as and considered
legally a custodian. The Escrow Agent shall be entitled to rely conclusively
upon the written notice provided in Section 5 and may assume the genuineness of
all signatures and documents and the authority of all signatories. The Escrow
Agent shall have no liability except for gross negligence or willful misconduct
in the performance of its duties under this Escrow Agreement. Kendle and the
Selling Group, collectively, shall each assume and pay one half (1/2) of all
costs and expenses of the Escrow Agent incurred in its capacity as the Escrow
Agent under this Escrow Agreement. The fees of the Escrow Agent are set forth on
Exhibit "B" attached to the Primary Escrow Agreement and incorporated herein.

                  4.       RESIGNATION; DISAGREEMENTS.

                           (a) Escrow Agent (and any successor Escrow Agent) may
at any time resign as such by delivering the Escrow Property to any successor
Escrow Agent designated by the other parties hereto in writing, or to any court
of competent jurisdiction as provided below. The resignation of Escrow Agent
will take effect on the earlier of (i) the appointment of a successor (including
a court of competent jurisdiction), or (ii) the day which is thirty (30) days
after the date of delivery of its written notice of resignation to the other
parties hereto. If at that



                                       15
<PAGE>   16

time Escrow Agent has not received a designation of a successor Escrow Agent,
Escrow Agent's sole responsibility after that time shall be to retain and
safeguard the Escrow Property until receipt of a designation of successor Escrow
Agent or a joint written disposition instruction by the other parties hereto or
a final order of a court of competent jurisdiction.

                           (b) In the event of any disagreement between the
other parties hereto resulting in adverse claims or demands being made in
connection with the Escrow Property or in the event that Escrow Agent is in
doubt as to what action it should take hereunder, Escrow Agent shall be entitled
to retain the Escrow Property until Escrow Agent shall have received (i) a final
order of a court of competent jurisdiction directing delivery of the Escrow
Property, or (ii) a written agreement executed by the other parties hereto
directing delivery of the Escrow Property, in which event Escrow Agent shall
disburse the Escrow Property in accordance with such order or agreement. Escrow
Agent shall act on such court order without further question.

                  5.       TERMINATION AND DISTRIBUTION OF ESCROW.

                           (a) TERMINATION. This Escrow Agreement shall
terminate on the date upon which the Escrow Agent shall have fully distributed
the Escrow Property as provided herein.

                           (b) CLAIM NOTICES. Simultaneously with any deposit of
any cash or Kendle shares hereunder in accordance with the U.S. Purchase
Agreement and the Primary Escrow Agreement, U.S. Purchaser shall give to the
Escrow Agent a notice which (i) affirms that the Purchasing Group believes that
the members of the Selling Group are liable to the U.S. or Canadian Purchaser
under the U.S. Purchase Agreement or the Canadian Purchase Agreement for
breaches of representations or warranties and (ii) states a specific amount (at
least equal to the value of the Escrow Property than being deposited) (the
"Claimed Amount") which, as a result of the factual basis underlying such
notice, the Purchasing Group, in good faith, believes it is owed, by the Selling
Group (any such notice being herein referred to as a "Claim Notice"), the Escrow
Agent shall continue to hold in escrow the Claimed Amount stated in such notice
(or, if less, the Escrow Property then being deposited) until (A) it shall
receive further instructions as to the disposition of such property in a writing
signed by Kendle and either of the Sellers or (B) it shall be otherwise ordered
by a court of competent jurisdiction. The parties acknowledge that there may be
multiple Claim Notices given by the Purchasing Group during the term hereof. The
Escrow Agent shall deliver a copy of each Claim Notice received by it to the
appropriate Seller. The U.S. Purchaser represents that it has tendered to the
Escrow Agent a Claim Notice, conforming to the above, with respect to the
initial Escrow Property deposited with the Escrow Agent hereunder.



                                       16
<PAGE>   17

                           (c) JOINT WRITTEN DIRECTION. Notwithstanding any
provision in this Section 5 to the contrary, the Escrow Agent may make payments
from the Escrow Property, or from any Seller's Accretions, at any time upon
receipt of a joint written direction from Kendle and either of the Sellers (a
"Joint Written Direction").

                  6. DUTIES OF ESCROW AGENT. The duties of the Escrow Agent
under this Escrow Agreement shall be entirely administrative and the Escrow
Agent shall not be liable to any third party as a result of any action or
omission taken or made by it, if taken in good faith, except for gross
negligence or willful misconduct in performing its duties. In the event of
disagreement or dispute between Kendle and the Selling Group with respect to
disposition of the Escrow Property, the Escrow Agent shall have the right to
initiate an appropriate legal proceeding to obtain a judicial determination of
the respective parties' rights to the Escrow Property. No rights are intended to
be granted to any third party hereunder. Kendle and the Selling Group shall
severally (each being responsible for a maximum of fifty percent (50%) of the
indemnity account) indemnify and hold harmless the Escrow Agent and reimburse
the Escrow Agent from and for any and all liability, costs and expenses,
including reasonable attorneys' fees, the Escrow Agent may suffer or incur by
reason of its execution and performance of this Escrow Agreement except for any
such liability, costs or expenses (including attorneys fees) which is a result
of Escrow Agent's own gross negligence or willful misconduct. The Escrow Agent
shall have no duties except those which are expressly set forth herein, and it
shall not be bound by any notice of a claim, or demand with respect thereto, or
any waiver, modification, amendment, termination or recission of this Escrow
Agreement, unless in writing received by it and signed by Kendle and either
Seller.

                  In the event that the Escrow Agent shall find it necessary to
consult with counsel of its own choosing in connection with this Escrow
Agreement, the Escrow Agent shall not incur any liability for any action taken
in good faith in accordance with such advice. Kendle and the Selling Group,
jointly and severally, shall indemnify and hold harmless the Escrow Agent for
any liability, loss, claim or damage incurred by the Escrow Agent in connection
with this Escrow except for any such liability, costs, expenses (including
reasonable attorneys' fees), loss, claims or damage which is a result of Escrow
Agent's own gross negligence or willful misconduct. This indemnification shall
survive termination of this Escrow Agreement. Kendle and the Selling Group agree
that Kendle, on the one hand, and the Selling Group, collectively, on the other
hand, shall each assume and pay fifty percent (50%) of all amounts due to Escrow
Agent as a result of this indemnification.

                  Escrow Agent is not a party to, and is not bound by, any
agreement which may be evidenced by, or arise out, the foregoing instruction,
other than as expressly set forth herein. In the event that any of the terms and
provisions of any



                                       17
<PAGE>   18

other agreement (excluding any amendment to this Escrow Agreement) between any
of the parties hereto, conflict or are inconsistent with any of the provisions
of this Escrow Agreement, the terms and provisions of this Escrow Agreement
shall govern and control in all respects.

required or permitted to be given under this Escrow Agreement shall be in

         3. ESCROW AGENT AS CUSTODIAN; EXPENSES. The Escrow Agent shall, for all
purposes of this Escrow Agreement, be treated as and considered legally a

         4.       RESIGNATION; DISAGREEMENTS.

                  (a) Escrow Agent (and any successor Escrow Agent) may at any
         time resign as such by delivering the Escrow Fund to any successor
         Escrow Agent designated by the other parties hereto in writing, or to
         any court of competent jurisdiction as provided below. The resignation

         National Market System during the twenty (20) trading days prior to
         either the date of a disputed claim is finally determined or, if a
         claim is not disputed, the date of release.

         6. DUTIES OF ESCROW AGENT. The duties of the Escrow Agent under this
Escrow Agreement shall be entirely administrative and the Escrow Agent shall not
be liable to any third party as a result of any action or omission taken or made
by it, if taken in good faith, except for gross negligence or willful misconduct
in performing its duties. In the event of disagreement or dispute between Kendle
and Seller with respect to disposition of the Escrow Fund, the Escrow Agent
shall promptly initiate an appropriate legal proceeding to obtain a judicial
determination of the respective parties' rights to the Escrow Fund. No rights
are intended to be granted to any third party hereunder. Kendle and Seller shall
severally (each being responsible for fifty percent (50%) of the indemnity
account) indemnify, defend and hold harmless the Escrow Agent and reimburse the
Escrow Agent from and for any and all liability, costs and expenses, including
reasonable attorneys' fees, the Escrow Agent may suffer or incur by reason of
its execution and performance of this Escrow Agreement. The Escrow Agent shall
have no duties except those which are expressly set forth herein, and it shall
not be bound by any notice of a claim, or demand with respect thereto, or any
waiver, modification, amendment, termination or recision of this Escrow
Agreement, unless in writing received by it and signed by Kendle and/or Seller.

                  In the event that the Escrow Agent shall find it necessary to
consult with counsel of its own choosing in connection with this Escrow
Agreement, the Escrow Agent shall not incur any liability for any action taken
in good faith in accordance with such advice. Kendle and Seller, jointly and
severally, shall indemnify and hold harmless the Escrow Agent for any liability,
loss, claim or damage incurred by the Escrow Agent in connection with this
Escrow except for any such liability, costs, expenses (including reasonable
attorneys' fees), loss, claims or damage which is a result of Escrow Agent's own
gross negligence or willful misconduct. This indemnification shall survive
termination of this Escrow Agreement. Kendle and Seller agree that Kendle, on
the one hand, and Seller, collectively, on the other hand, shall each assume and
pay fifty percent (50%) of all amounts due to Escrow Agent as a result of this
indemnification.

                  Escrow Agent is not a party to, and is not bound by, any
agreement which may be evidenced by, or arise out, the foregoing instruction,
other than as expressly set forth herein. In the event that any of the terms and
provisions of any other agreement (excluding any amendment to this Escrow
Agreement) between any of the parties hereto, conflict or are inconsistent with
any of the provisions of this Escrow Agreement, the terms and provisions of this
Escrow Agreement shall govern and control in all respects.

MANAGEMENT'S DISCUSSION AND ANALYSIS

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information set forth and discussed below is derived from the Company's
Consolidated Financial Statements included herein and should be read in
conjunction therewith.

COMPANY OVERVIEW

Kendle International Inc. (the "Company") is an international contract research
organization (CRO) that provides integrated clinical research services,
including Phase I through IV drug development, on a contract basis to the
pharmaceutical and biotechnology industries. Kendle also provides
organizational, meeting management and publication services to professional
organizations and pharmaceutical companies through its subsidiary, Health Care
Communications, Inc. (HCC). With its acquisition of HCC, the Company is now
managed through two reportable segments, the contract research services group
and the medical communications group. The medical communications group includes
only HCC.

The Company's contracts are generally fixed price, with some variable compo-
nents, and range in duration from a few months to several years. The contract
typically requires a portion of the contract fee to be paid at the time the
contract is entered into and the balance is received in installments over the
contract's duration, in most cases on a milestone achievement basis. Net
revenues from contracts are generally recognized on the percentage of completion
method, measured principally by the total costs incurred as a percentage of
estimated total costs for each contract. The estimated total costs of contracts
are reviewed and revised periodically throughout the lives of the contracts with
adjustments to revenues resulting from such revisions being recorded on a
cumulative basis in the period in which the revisions are made. Additionally,
the Company incurs costs, in excess of contract amounts, in sub- contracting
with third-party investigators. Such costs, which are reimbursable by its
customers, are excluded from direct costs and net revenues.

Direct costs consist of compensation and related fringe benefits for project-
related associates, unreimbursed project-related costs and an allocation of
indirect costs including facilities, information systems, and other costs.
Selling, general and administrative expenses consist of compensation and related
fringe benefits for sales and administrative associates and professional
services, as well as unallocated costs related to facilities, information
systems and other costs.

ACQUISITIONS

In 1999, the Company acquired Research Consultants (International) Holdings
Limited (IRC), a U.K.-based regulatory affairs company, ESCLI S.A., a CRO based
in Paris, France and Specialist Monitoring Services Limited, a U.K.-based CRO.
The Company also acquired HCC, a U.S.-based medical communications company.

The acquisitions have been accounted for using the purchase method of
accounting, with goodwill as a result of the transactions being amortized over
thirty years. The results of operations are included in the Company's
consolidated statements of income from the dates of acquisition.

RESULTS OF OPERATIONS

Net Revenues

Net revenues increased to $117.2 million for the year ended December 31, 1999.
This compares to $89.5 million and $44.2 million for the years ended December
31, 1998, and 1997, respectively. The 31% increase in net revenues in 1999 was
comprised of organic growth of 18% and growth from acquisitions of 13%. The 102%
increase in net revenues in 1998 was comprised of organic growth of 64% and
growth from acquisitions of 38%. Approximately 30%, 25%, and 23% of the
Company's net revenues in 1999, 1998, and 1997, respectively were derived from
the Company's operations outside of the United States. Revenues from G.D. Searle
and Co. accounted for approximately 24%, 38%, and 54% of net revenues for the
years ended December 31, 1999, 1998, and 1997, respectively. Revenues from
Centocor, Inc. accounted for approximately 18% of net revenues for the year
ended December 31, 1999 and were less than 10% in 1998 and 1997.

The CRO industry in general continues to be dependent on the research and
development efforts of the principal pharmaceutical and biotechnology com-
panies as major customers, and the Company believes this dependence will
continue. The loss of business from any of the Company's major customers
could have a material adverse effect on the Company.

Depreciation and Amortization                1.6         4.7         6.7

Direct costs increased by $16.1 million, or 36%, for the year ended December 31,
1999 as compared to 1998. As compared to 1997, direct costs increased by $21.0
million, or 88%, in 1998. The increases are a result of increases in direct
salaries and fringe benefits to support the increases in net revenues for the
periods. Direct costs expressed as a percentage of net revenues were 52.1%,
50.1%, and 54.0% for the years ended December 31, 1999, 1998, and 1997,
respectively. The change in these costs as a percentage of net revenues is due
to the varying levels of profitability within the mix of contracts among
periods.

Selling, general and administrative expenses increased by $8.1 million, or 28%,
for the year ended December 31, 1999 as compared to 1998. These expenses
increased $15.7 million, or 115%, for the year ended December 31, 1998 as
compared to 1997. The increases are primarily comprised of increases in
salaries and benefits, rent and other facility expenses, travel, contractual
services, recruiting, marketing, advertising and other expenses resulting from
the Company's continued efforts to increase its infrastructure to support the
growth in business. In 1999, the Company incurred significant costs to hire and
retain new business development associates in connection with the implementation
of its strategic account management program. Selling, general and administrative
expenses as a percentage of net revenues were 31.9% for the year ended December
31, 1999, 32.6% in 1998, and 30.6% in 1997. In 1998 and the first half of 1999,
the Company made significant investments in infrastructure to support the
growth in business. These investments caused this percentage to be higher in
1998 as compared to 1997; however, in the last half of 1999, the Company was
able to leverage these investments allowing this percentage to decrease in 1999
as compared to 1998.

Depreciation and amortization expense increases from 1997 through 1999 are the
result of the amortization of goodwill as a result of the Company's acquisi-
tions and an increase in depreciation expense as a result of the Company's
increased level of capital expenditures.

INCOME TAXES

The Company's effective tax rate was 39.1% for the year ended December 31, 1999
as compared to 40.6% in 1998 and 28.4% in 1997. The decrease in the Company's
effective tax rate from 1998 to 1999 is due to the Company's investment in tax
advantaged securities in 1999 as compared to taxable securities in 1998 in order
to achieve a better after-tax return on these investments. There were no income
taxes recorded with respect to periods prior to the Company's August, 1997
initial public offering (IPO) as the Company was taxed as an S corporation.

SEGMENT INFORMATION

Net revenues from the contract research services group and the medical
communications group were $114.5 million and $2.7 million, respectively, for the
year ended December 31, 1999. Net income from the contract research services
group and the medical communications group was $7.0 million and $0.7 million,
respectively, for the year ended December 31, 1999. Information is not presented
for prior years because the Company had not yet acquired HCC, and managed its
business as one segment.


LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents decreased by $8.3 million for the year ended December
31, 1999 as a result of cash used in operating and investing activities of $5.0
million and $11.9 million respectively, offset by cash provided by financing
activities of $9.2 million. Net cash used in operating activities resulted from
net income primarily offset by an increase in accounts receivable. Fluctuations
in accounts receivable and advance billings occur on a regular basis as services
are performed, milestones or other billing criteria are achieved, invoices are
sent to customers, and

payments for outstanding accounts receivable are collected from customers. Such
activity varies by individual customer and contract. Accounts receivable, net of
advance billings, increased from $18.8 million at December 31, 1998 to $36.6
million at December 31, 1999. During 1999, the Company experienced customers
becoming more aggressive in managing their own cash flow which caused an
increase in the amount of time certain customers took to pay their invoices.
Additionally, certain contracts contain milestone payment schedules that require
a larger portion of the contract value to be paid near the end of the study,
when compared to historical milestone payment schedules. Because the Company is
in the latter stages of several of these contracts, the payment schedules have
caused the unbilled accounts receivable to grow and accordingly have had a
negative impact on the Company's operating cash flow. The Company does not
anticipate any difficulties in achieving the remaining milestones and
collecting the unbilled accounts receivable related to these contracts.

Investing activities for the year ended December 31, 1999 consisted primarily of
the costs related to the Company's acquisitions of $20.7 million (net of cash
acquired) and capital expenditures of $10.8 million offset by net proceeds from
sales and purchases of available for sale securities of $20.9 million.

Financing activities for the year ended December 31, 1999 consisted primarily of
net borrowings under the Company's credit facility of $8.7 million.


Cash and cash equivalents decreased by $1.8 million for the year ended December
31, 1998 as a result of cash provided by financing activities of $50.6 million
offset by cash used in operating and investing activities of $1.9 million and
$50.7 million, respectively. Net cash used in operating activities resulted pri-
marily from net income offset by additional working capital used to support the
Company's growth.

Investing activities during 1998 consisted primarily of the costs related to the
Company's acquisition of $12.7 million (net of cash acquired) and the purchase
of available for sale securities (net of proceeds) of $30.4 million. Financing
activities consisted primarily of net proceeds of $51.4 million as a result of
the Company's follow-on offering of Common Stock.

Cash and cash equivalents increased by $13.7 million for the year ended December
31, 1997 as a result of cash provided by operating and financing activities of
$6.5 million and $41.6 million, respectively, offset by cash used in investing
activities of $34.4 million. Net cash provided by operating activities resulted
from net income and the net change in working capital items. Investing
activities during the year consisted primarily of the costs related to the
Company's acquisitions of $22.9 million (net of cash acquired). Financing
activities consisted primarily of $45.2 million of net proceeds from the
Company's IPO.

The Company had available for sale securities totaling $19.5 million and $40.8
million at December 31, 1999 and 1998, respectively.

Capital expenditures were $10.8 million, $7.3 million and $3.1 million in 1999,
1998, and 1997, respectively.

The Company has a $30 million credit facility with certain banks. The credit
facility bears interest at a rate equal to either (a) LIBOR plus the Applicable
Percentage (as defined) or (b) the higher of the Bank's prime rate or the
Federal Funds rate plus 0.50%, plus the Applicable Percentage. All amounts
outstanding thereunder become due and payable in February, 2001. The facility
includes various restrictive covenants including the maintenance of certain
fixed coverage and leverage ratios as well as minimum net worth levels. At
December 31, 1999, there was $8.7 million outstanding under the credit facility.

The Company's primary cash needs on both a short-term and long-term basis are
for the payment of salaries and fringe benefits, hiring and recruiting expenses,
business development costs, capital expenditures, acquisitions, and
facility-related expenses. The Company believes that its existing capital
resources, together with cash flows from operations and borrowing capacity under
its credit facility, will be sufficient to meet its foreseeable cash needs. In
the future, the Company will continue to consider acquiring businesses to
enhance its service offerings, therapeutic base and global presence. Any such
acquisitions may require additional external financings and the Company may from
time to time seek to obtain funds from public or private issuances of equity or
debt securities. There can be no assurance that such financings will be
available on terms acceptable to the Company.

FOREIGN CURRENCY

The Company operates on a global basis and is therefore exposed to various types
of currency risks. Two specific transaction risks arise from the nature of the
contracts the Company executes with its customers since contracts are
occasionally denominated in a currency different than the particular
subsidiary's local currency. This contract currency denomination issue is
applicable only to a portion of the contracts executed by the Company's foreign
subsidiaries. The first risk occurs as revenue recognized for services rendered
is denominated in a currency different from the currency in which the
subsidiary's expenses are incurred. As a result, the subsidiary's net revenues
and resultant net income can be affected by fluctuations in exchange rates.
Although some contracts state that currency fluctuations from the rates in
effect at the time the contract is executed up to a specified threshold
(generally plus or minus a few percentage points) will be absorbed by the
Company, and fluctuations in excess of the threshold are the customer's
responsibility, most contracts do not specifically address responsibility for
currency fluctuations. Historically, fluctuations in exchange rates from those
in effect at the time contracts were executed have not had a material effect
upon the Company's consolidated financial results.

The second risk results from the passage of time between the invoicing of
customers under these contracts and the ultimate collection of customer payments
against such invoices. Because the contract is denominated in a currency other
than the subsidiary's local currency, the Company recognizes a receivable at the
time of invoicing at the local currency equivalent of the foreign currency
invoice amount. Changes in exchange rates from the time the invoice is prepared
until the payment from the customer is received will result in the Company
receiving either more or less in local currency than the local currency
equivalent of the invoice amount at the time the invoice was prepared and the
receivable established. This difference is recognized by the Company as a
foreign currency transaction gain or loss, as applicable, and is reported in
other income (expense) in the consolidated statements of income.

The Company's consolidated financial statements are denominated in U.S. dollars.
Accordingly, changes in exchange rates between the applicable foreign currency
and the U.S. dollar will affect the translation of each foreign subsidiary's
financial results into U.S. dollars for purposes of reporting consolidated
financial statements. The Company's foreign subsidiaries translate their
financial results from local currency into U.S. dollars as follows: income
statement accounts are translated at average exchange rates for the period;
balance sheet asset and liability accounts are translated at end of period
exchange rates; and equity accounts are translated at historical exchange rates.
Translation of the balance sheet in this manner affects the shareholders' equity
account, referred to as the foreign currency translation adjustment account.
This account exists only in the foreign subsidiary's U.S. dollar balance sheet
and is necessary to keep the foreign balance sheet stated in U.S. dollars in
balance. Foreign currency translation adjustments, reported as a separate
component of shareholders' equity, were ($1.8) million at December 31, 1999
compared to $564,000 at December 31, 1998.

IMPACT OF THE YEAR 2000

The Company initiated a program in 1998 to identify and address issues associ-
ated with the ability of its date-sensitive software to recognize the Year 2000
properly. The Company spent approximately $900,000 in order to prepare for the
Year 2000 of which approximately 20% was paid to third party service providers.
The Company has not experienced any significant problems associated with the
date change and expects to incur approximately $50,000 in expense in 2000 as it
continues to monitor and test ongoing compliance. While the Company does not
anticipate any significant problems regarding the Year 2000, there can be no
assurance that problems will not arise in the future.

NEW ACCOUNTING PRONOUNCEMENTS

In June, 1998, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 is effective for all fiscal
quarters of all fiscal years beginning after June 15, 2000 (January 1, 2001 for
the Company). SFAS No. 133 requires that all derivative instruments be recorded
on the balance sheet at their fair value. Changes in the fair value of
derivatives are recorded each period in current earnings or other comprehensive
income, depending on whether a derivative is designated as part of a hedge
transaction and, if it is, the type of hedge transaction. Since its only
derivative transaction has historically been the occasional use of foreign
currency exchange rate hedge instruments within a year, management of the
Company anticipates that the adoption of SFAS No. 133 will not have a
significant effect on the Company's results of operations or its financial
position.

Implementation of these strategies and the achievement of such financial
performance are each subject to numerous conditions, uncertainties and risk
factors. Factors which could cause actual performance to differ materially from
these forward-looking statements include, without limitation, factors discussed
in conjunction with a forward-looking statement, changes in general economic
conditions, competitive factors, outsourcing trends in the pharmaceutical
industry, the Company's ability to manage growth and to continue to attract and
retain qualified personnel, the Company's ability to complete additional
acquisitions and to integrate newly acquired businesses, the Company's ability
to penetrate new markets, competition and consolidation within the industry, the
ability of joint venture businesses to be integrated with the Company's
operations, cancellation or delay of contracts, the progress of ongoing
projects, cost overruns, the Company's sales cycle, the ability to maintain
large customer contracts or to enter into new contracts, the effects of exchange
rate fluctuations, and the other risk factors set forth in the Company's SEC
filings, copies of which are available upon request from the Company's investor
relations department.

Kendle International Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, shareholders' equity and cash flows present
fairly, in all material respects, the financial position of Kendle International
Inc. and its subsidiaries (the "Company") at December 31, 1999 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States. 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 of these statements in accordance with auditing standards generally
accepted in the United States which 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, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES:

Nature of Business

Kendle International Inc. (the "Company") is an international contract research
organization (CRO) providing integrated clinical research services, including
Phase I through IV drug development, on a contract basis to the pharmaceutical
and biotechnology industries. The Company also provides organizational, meeting
management, and publication services to professional organizations and
pharmaceutical companies through its subsidiary, Health Care Communications Inc.
(HCC). The Company has operations in North America, Europe and Asia.

Principles of Consolidation and Organization

The consolidated financial statements include the financial information of
Kendle International Inc. and its wholly-owned subsidiaries. Investments in
unconsolidated companies, which are at least 20% owned and the Company can
exercise significant influence but not control, are carried at cost plus equity
in undistributed earnings since acquisition. Investments in unconsolidated
companies, which are less than 20% owned and the Company cannot exercise
significant influence, are carried at cost.

All intercompany accounts and transactions have been eliminated. The results of
operations of the Company's wholly-owned subsidiaries have been included in the
consolidated financial statements of the Company from the respective dates of
acquisition.

Certain amounts reflected in the prior years' consolidated financial statements
have been reclassified to be comparable with the current year.

Foreign Currency Translation

Assets and liabilities of the Company's foreign subsidiaries and investments are
translated into U.S. dollars at year-end exchange rates. Income statement
accounts are translated at average exchange rates for the year. Resultant
translation adjustments are recorded as a separate component of shareholders'
equity. Foreign currency transaction gains and losses are included in the
consolidated statements of income.

As a significant percentage of the Company's cash flow from operations is
derived from operations outside the United States, the Company is subject to the
risks of currency exchange rate fluctuations.

Cash and Cash Equivalents

Cash and cash equivalents consist of demand deposits and money market funds held
with a financial institution, with an initial maturity of three months or less.

The Company maintains its demand deposits with certain financial institutions.
The balance of one account occasionally exceeds the maximum U.S. federally
insured amount. Additionally, there is no state insurance coverage on bank
balances held in The Netherlands.

Available for Sale Securities

Investments purchased with initial maturities greater than three months are
classified as available for sale securities and consist of highly liquid debt
securities. These securities are stated in the consolidated financial statements
at market value. Realized gains and losses are included in the consolidated
statements of income, calculated based on the weighted average cost of the
investments. Unrealized gains and losses, net of tax, are reported as a separate
component of shareholders' equity.

Revenue Recognition

Revenues are earned by performing services primarily under fixed-price
contracts. Net revenues from contracts are generally recognized on the
percentage of completion method, measured principally by the total costs
incurred as a percentage of estimated total costs for each contract. This method
is used because management considers total costs incurred to be the best
available measure of progress on these contracts.The estimated total costs of
contracts are reviewed and revised periodically throughout the lives of the
contracts with adjustments to revenues resulting from such revisions being
recorded on a cumulative basis in the period in which the revisions are made.
Hence, the effect of the changes on future periods of contract performance is
recognized as if the revised estimates had been the original estimates. Because
of the inherent uncertainties in estimating costs, it is at least reasonably
possible that the estimates used will change in the near term and could result
in a material change.


                                                       KENDLE INTERNATIONAL INC.

                                       34
<PAGE>   17

Direct costs include direct labor costs and indirect costs related to contract
performance, such as indirect labor, supplies, depreciation, rent and utilities.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are recognized in the
period in which such losses become known.

Amendments to contracts resulting in revisions to revenues and costs are
recognized in the period in which the revisions are negotiated. Included in
accounts receivable are unbilled accounts receivable, which represent revenue
recognized in excess of amounts billed. Advance billings represent amounts
billed in excess of revenue recognized.

Concentration of Credit Risk

Accounts receivable represents amounts due from customers who are concentrated
mainly in the pharmaceutical and biotechnology industries. The concentration
of credit risk is subject to the financial and industry conditions of the
Company's customers. The Company does not require collateral or other securities
to support customer receivables. The Company monitors the creditworthiness of
its customers, and credit losses have been immaterial and consistent with
management's expectations. Management considers the likelihood of material
credit risk exposure as remote.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed over
estimated useful lives of two to ten years using the straight-line method.
Repairs and maintenance are charged to expense as incurred. Upon disposition,
the asset and the related accumulated depreciation are relieved and any gains or
losses are reflected in operations.

Equipment under capital leases is recorded at the present value of future mini-
mum lease payments and is amortized over the estimated useful lives of the
assets, not to exceed the terms of the related leases. Accumulated amortiza-
tion on equipment under capital leases was $2.7 million and $1.9 million at
December 31, 1999 and 1998, respectively.

Internally Developed Software

The Company capitalizes costs incurred to internally develop software used
primarily in the Company's proprietary clinical trial and data management. These
costs are amortized on a straight-line basis over the estimated useful
life of the product, not to exceed five years. Unamortized software costs
included in the consolidated balance sheets at December 31, 1999 and 1998 were
$6.2 million and $2.0 million, respectively. The related accumulated
amortization at December 31, 1999 and 1998 was $0.7 million and $0.2 million,
respectively.

Excess of Purchase Price Over Net Assets Acquired

The excess of cost over the fair value of the net assets acquired in the
Company's acquisitions is being amortized on a straight-line basis over a thirty
year period. Excess of purchase price over net assets acquired is evaluated
periodically as events or circumstances indicate a possible inability to recover
its carrying amount. Such evaluation will be based on various analyses,
including cash flow and profitability projections that incorporate, as
applicable, the impact on existing company businesses. The analyses will
necessarily involve significant management judgment to evaluate the capacity of
an acquired business to perform within projections. If future expected
undiscounted cash flows are insufficient to recover the carrying amount of the
asset, an impairment loss will be recognized based on discounted expected future
cash flows. Accumulated amortization of the excess of purchase price over net
assets acquired was $4.0 million and $2.0 million at December 31, 1999 and 1998,
respectively.

Investigator and Project Costs

In addition to various contract costs previously described, the Company incurs
costs, in excess of contract amounts, which are reimbursable by its customers.
Such pass-through costs incurred, but not yet reimbursed, are reflected as a
current asset in the accompanying consolidated balance sheets. Advances from
customers for such costs not yet incurred are reflected as a current liability.
Such costs and reimbursement for such costs are excluded from direct costs and
net revenues and totaled $33.3 million, $41.6 million, and $48.7 million for the
years ended December 31, 1999, 1998, and 1997, respectively.

Net Income Per Share Data

Net income per basic share is computed using the weighted average common shares
outstanding. Net income per diluted share is computed using the
weighted average common shares and potential common shares outstanding.



                                                       KENDLE INTERNATIONAL INC.

                                       35
<PAGE>   18

The weighted average shares used in computing net income per diluted share
have been calculated as follows:

   (IN THOUSANDS)                                1999           1998       1997
- --------------------------------------------------------------------------------
  Weighted average common shares outstanding    11,251         9,589      5,055

  Stock options                                    507           637        610

  Contingently issuable shares                      68

  Stock purchase warrants                                                    98
- --------------------------------------------------------------------------------
  Weighted average shares                       11,826        10,226      5,763
- --------------------------------------------------------------------------------


For additional disclosure regarding the contingently issuable shares, see Note
12, Acquisitions.

Options to purchase approximately 398,000 and 89,000 shares of Common Stock were
outstanding during 1999 and 1998 respectively, but were not included in the
computation of earnings per diluted share because the options' exercise price
was greater than the average market price of the common shares and, therefore,
the effect would be antidilutive.

Income Taxes

Since August, 1997, upon terminating its S corporation status, the Company has
recorded deferred tax assets and liabilities based on temporary differences
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect in the year in which the differences are expected to
reverse.

For periods prior to August, 1997, the consolidated financial statements of the
Company do not include a provision for income taxes because taxable income or
loss of the Company was included in the income tax returns of the individual
shareholders under the S corporation election. The consolidated statements of
income include the pro forma income tax provision on taxable income for
financial reporting purposes using statutory federal, state and local rates that
would have resulted had the Company filed corporate tax returns during these
periods.

Stock Options

The Company accounts for stock options issued to associates in accordance
with Accounting Principles Board Opinion (APB) No. 25, "Accounting for Stock
Issued to Employees." Under APB No. 25, the Company recognizes expense
based on the intrinsic value of the options.

Use of Estimates

The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements

In June, 1998, the Financial Accounting Standards Board (FASB) issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No.
133 is effective for all fiscal quarters of all fiscal years beginning after
June 15, 2000 (January 1, 2001 for the Company). SFAS No. 133 requires that all
derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives are recorded each period in current
earnings or other comprehensive income, depending on whether a derivative is
designated as part of a hedge transaction and, if it is, the type of hedge
transaction. Since the Company's only derivative transaction has historically
been the use of foreign currency exchange rate hedge instruments occasionally
within a year, management anticipates that the adoption of SFAS No. 133 will not
have a significant effect on the Company's results of operations or its
financial position.

2. AVAILABLE FOR SALE SECURITIES:

The fair value of available for sale securities is estimated based on quoted
market prices. Information related to the Company's available for sale
securities at December 31, 1999 and 1998 is as follows:

7. DEBT:

The Company has a $30 million credit facility (the "Amended and Restated Senior
Credit Facility") which bears interest at either LIBOR plus the Applicable
Percentage (as defined) or the higher of the bank's prime rate or the Federal
Funds rate plus 0.50%, plus the Applicable Percentage. All amounts
outstanding thereunder are payable in February, 2001. The Amended and Restated
Senior Credit Facility contains various restrictive financial covenants,
including the maintenance of certain fixed coverage and leverage ratios and
minimum net worth levels. Amounts outstanding under this credit facility totaled
$8.7 million at December 31, 1999. There were no amounts outstanding under the
facility at December 31, 1998. Interest is payable on $4.0 million of the
outstanding balance at a rate of 7.0%, and on the remaining $4.7 million at a
rate of 8.5%.

8. EMPLOYEE BENEFIT PLANS:

401(k) Plan

The Company maintains a 401(k) retirement plan covering substantially all U.S.
associates who have completed at least six months of service and meet mini- mum
age requirements. The Company makes a matching contribution of 25% of each
participant's contribution of up to 6% of salary. The Company's matching
contribution to this plan totaled approximately $306,000, $239,000, and $31,000
for the years ended December 31, 1999, 1998, and 1997, respectively.

Employee Stock Purchase Plan

In 1998, the Company's Board of Directors adopted the Kendle International Inc.
Employee Stock Purchase Plan (the "Purchase Plan") which is intended to pro-
vide eligible employees an opportunity to acquire the Company's Common Stock.
Participating employees have the option to purchase shares at 85% of the lower
of the fair market value of the Common Stock on the first or last day of the
Purchase Period. The Purchase Period is defined as the twelve month period
beginning on July 1 of each year. The Purchase Plan is intended to qualify as an
"employee stock purchase plan" under Section 423 of the Internal Revenue Code of
1986, as amended. The Board of Directors has reserved 500,000 shares of Common
Stock for issuance under the Purchase Plan. During 1999, 46,747 shares were
purchased under the Purchase Plan. At December 31, 1999, 453,253 shares were
available for issuance under the Purchase Plan.

Incentive Stock Option and Stock Incentive Plan

In 1997, the Company established a plan that provides for the grant of up to
1,000,000 stock options, consisting of both incentive and non-qualified stock
options (the "1997 Plan"). Participation in the 1997 Plan is at the discretion
of the Board of Directors' Compensation Subcommittee, which is responsible for
administration of the Plan. The exercise price of incentive stock options
granted under the 1997 Plan must be no less than the fair market value of the
Common Stock, as determined under the 1997 Plan provisions, at the date the
option is granted (110% of fair market value for shareholders owning more than
10% of the Company's Common Stock). The exercise price of non-qualified stock
options must be no less than 95% of the fair market value of the Common Stock at
the date the option is granted. The vesting provisions of the options granted
under the 1997 Plan are determined at the discretion of the Compensation
Subcommittee of the Board of Directors. The options generally expire either 90
days after termination of employment or, if earlier, ten years after date of
grant. No options can be granted after August, 2007. The Company has reserved
1,000,000 shares of Common Stock for the 1997 Plan, of which 169,300 are
available for grant at December 31, 1999.

The 1997 Plan replaced a similar plan under which 531,298 options were out-
standing at December 31, 1999.

Aggregate stock option activity during 1999, 1998, and 1997 was as follows:

The weighted average fair value of the options granted in 1999, 1998, and 1997
was estimated as $9.30, $15.35, and $5.37, respectively, on the date of grant
using the Black-Scholes option-pricing model with the following assumptions:
expected dividend yield: zero; risk-free interest rate: 6.4% in 1999, 5.0% in
1998 and a range from 5.6% to 7.69% in 1997; expected volatility: 75.6% for
grants made during 1999, 63.5% for grants made during 1998, 58.3% for grants
made between August 22 and December 31, 1997 and zero for grants made prior to
August 22, 1997; and an expected holding period of seven years. A summary of
options outstanding and exercisable at December 31, 1999 is as follows:

certain associates, including all Executive Officers of the Company. These
Agreements, subject to annual review by the Company's Board of Directors, expire
on December 31, 2000, and will be automatically extended in one year increments
unless canceled by the Company. These Agreements provide for specified benefits
in the event of a change in control, as defined in the Agreements. At December
31, 1999, the maximum amount which could be required to be paid under these
Agreements, if such events occur, is approximately $8.3 million.

11. SHAREHOLDERS' EQUITY:

In June, 1998, the Company completed its follow-on offering of 2,415,000 shares
of Common Stock at a price to the public of $23.50 per share. Of the 2,415,000
shares sold, 2,315,000 were sold by the Company and 100,000 shares were sold by
selling shareholders. Proceeds to the Company approximated $51.4 million, net of
underwriting commissions and discounts and offering expenses of $3.0 million.

In August, 1997, the Company and its shareholders completed an initial public
offering (IPO) of 4,140,000 shares of Common Stock at a price to the public of
$14.00 per share. Of the 4,140,000 shares sold, 3,540,000 were sold by the
Company and 600,000 shares were sold by selling shareholders. Proceeds to the
Company approximated $45.2 million, net of underwriting commissions and

12. ACQUISITIONS:

Details of the Company's acquisitions since 1997 are listed below. The acquisi-
tions have been accounted for using the purchase method of accounting. The
escrow accounts referred to have been established at acquisition date to provide
indemnification of sellers' representations and warranties.

Valuation of the Common Stock issued in the 1999 and 1998 acquisitions was based
on an appraisal obtained by the Company which provided for a discount of the
shares due to lock-up restrictions and the lack of registration of the shares.

1999

In August, 1999, the Company acquired Specialist Monitoring Services Limited
(SMS), a contract research organization located in Crowthorne, United Kingdom.
Total acquisition costs consisted of approximately $7.5 million in cash and
141,680 shares of the Company's Common Stock. Of the total purchase price,
approximately $0.1 million in cash and 97,066 shares were placed in an escrow
account pursuant to the SMS Purchase Agreement, 50% to be released in August,
2000 and the remainder in August, 2001.

In July, 1999, the Company acquired Health Care Communications Inc. (HCC), a New
Jersey-based medical communications company, and HCC Health Care Communications
(1991) Ltd., a Toronto-based contract research organization. Total acquisition
costs consisted of approximately $5.7 million in cash and 174,559 shares of the
Company's Common Stock. Of the total purchase price, $0.5 million in cash and
31,943 shares were placed in an escrow account pursuant to the HCC Purchase
Agreement, 50% to be released in July, 2000 and the remainder in July, 2001.

The purchase price of HCC may be increased dependent upon the achievement of
certain operating results from acquisition date through December 31, 2001. Total
additional consideration could reach $10.9 million, payable 67% in cash and 33%
in shares of the Company's Common Stock, if HCC meets the targeted operating
results. For the period from acquisition date through December 31, 1999, HCC
reached its operating target, and $4.0 million has been accrued in other accrued
liabilities in the Company's December 31, 1999 consolidated balance sheet.

In June, 1999, the Company acquired ESCLI S.A., a contract research organization
located in Paris, France, for approximately $2.7 million in cash.

In January, 1999, the Company acquired Research Consultants (International)
Holdings Limited (IRC), a U.K.-based regulatory affairs company. Total acquisi-
tion costs consisted of approximately $4.4 million in cash and 87,558 shares of
the Company's Common Stock. The shares have been placed in an escrow account
pursuant to the IRC Share Purchase Agreement, 50% released in January, 2000 and
the remainder to be released in January, 2001.

1998

In February, 1998, the Company completed its acquisition of ACER/EXCEL Inc.
(ACER/EXCEL), headquartered in Cranford, New Jersey. Total acquisition costs
consisted of $14.4 million in cash and 987,574 shares of the Company's Common
Stock. A general escrow currently consisting of 186,336 shares of the Company's
Common Stock was scheduled to be released to the sellers, 50% in February, 1999
and the remainder in February, 2000. The scheduled releases of the escrow are
pending resolution of ongoing discussions between the parties.

1997

In September, 1997, the Company acquired GMI Gesellschaft fur Angewandte
Mathematik und Informatik mbH (gmi). Acquisition costs of $12.7 million
consisted of $10.0 million in cash and the issuance of 191,304 shares of the
Company's Common Stock, valued at $14 per share or $2.7 million.

The Company acquired U-Gene Research B.V. (U-Gene) in June, 1997 for
approximately $15.9 million in cash. Approximately $1.6 million of the purchase
price was payable to the U-Gene shareholders and was deposited in an escrow
account pursuant to the U-Gene Purchase Agreement, of which $1.1 million was
paid to the U-Gene shareholders in 1999, with the remainder returned to the
Company resulting in a purchase price reduction.

The following unaudited pro forma results of operations assume the 1999 and 1998
acquisitions occurred at the beginning of 1998:

13. INVESTMENT:

In January, 1999, the Company acquired a minority interest in Digineer, Inc.
(Digineer, formerly Component Software International, Inc.), an Internet
healthcare consulting and development company, for approximately $1.6 million in
cash and 19,995 shares of the Company's Common Stock. The Company's investment
in Digineer is being accounted for using the cost method of accounting for
investments. Additionally, the Company entered into a Multi-Year Strategic
Service Agreement with Digineer whereby the Company will pay Digineer $7.0
million over a four year period in exchange for strategic software consulting
and development services from Digineer. The Company has paid approximately $3.3
million relating to this agreement.

14. RELATED PARTY TRANSACTION:

The Company made payments in 1999, 1998, and 1997 totaling approximately $0.5
million, $0.4 million, and $0.4 million, respectively, to a construction company
owned by a relative of the Company's primary shareholder, for construction and
renovations at various Company locations.

15. EXTRAORDINARY ITEM:

In 1997, the Company recorded an extraordinary item for the early extinguish-
ment of indebtedness of $1.1 million, net of tax benefits of approximately $0.4
million. The extraordinary item resulted from the write-off of the debt dis-
count recorded in connection with long-term borrowings. Such borrowings were
made by the Company in connection with the acquisition of U-Gene prior to the
Company's IPO and were repaid with the proceeds of the IPO.

16. SEGMENT INFORMATION:

With its July, 1999 acquisition of HCC, the Company now manages through two
reportable segments, namely, the contract research services group and the
medical communications group. The contract research services group constitutes
the Company's core business and includes clinical trial management, clinical
data management, statistical analysis, medical writing, and regulatory
consultation and representation. The medical communications group, which
includes only HCC, provides organizational, meeting management, and publication
services to professional organizations and pharmaceutical companies. Corporate
overhead costs are included in the contract research services group and have not
been allocated. Information is not presented for the year ended December 31,
1998 because the Company had not yet acquired HCC, and therefore managed its
business in one segment.
