          (iv) any expenses directly or indirectly incurred in connection with
     the acquisition or the financing of the acquisition of the Company or the

          (v) any gain, loss, income or expense resulting from a change in the
     Company's accounting methods, principles or practices or a change in GAAP

          (b) By March 31, 1999, Buyer shall have prepared and delivered to

year ending


                                       -6-



December 31, 1998 (the "EBITDA Financial Statements") which statements shall
have been prepared in accordance with GAAP (including footnotes and other

provided in subparagraph (d) below, Buyer shall deliver the Earn-Out Payment to
Seller no later than April 30, 1999.

          (c) Buyer's calculation of 1998 EBITDA shall be used in determining
the Earn-Out Payment unless, within thirty (30) days following Seller's receipt
of the EBITDA Financial Statements, Seller has given Buyer notice (the "EBITDA
Dispute Notice") that Seller disputes Buyer's calculation, which notice shall
set forth in reasonable detail the exclusions or calculations being disputed in
good faith. In the event an EBITDA Dispute Notice is timely given to Buyer,
Seller and Buyer shall have fifteen (15) days to resolve the dispute and if not
resolved, the dispute shall be submitted to a nationally recognized "Big Six"
accounting firm or its successor (other than auditors used by Seller or Buyer or
any Affiliate of either within the past three (3) years, or their successors)
chosen by lot (the "EBITDA Arbitrator") which shall be instructed to arbitrate
such disputed item(s) and determine 1998 EBITDA within thirty (30) days. The
fees and expenses of the EBITDA Arbitrator shall be borne equally by Buyer and
Seller. The resolution of disputes by the EBITDA Arbitrator shall be set forth
in writing and shall be conclusive and binding upon and non-appealable by the
parties, and the determination of 1998 EBITDA shall become final upon the date
of such resolution, and may be entered as a final judgment in any court of
proper jurisdiction.

          (d) If an EBITDA Dispute Notice has been delivered in accordance with
subparagraph (c) above and the dispute has not been resolved by the Earn-Out due
date, (a) the amount not in dispute shall be paid as required hereunder, and (b)
the amount, if any, required to be paid as an adjustment shall be paid by Buyer
or Seller, as applicable, no later than 10 days after the dispute is resolved,
which amount shall bear interest, from May 1, 1999 until paid, at the rate equal
to the lower of (i) the maximum rate permitted by Applicable Law or (ii) two
percent (2%) plus the Prime Rate of Bank of Canada on May 1, 1999. In addition,
in the event that Buyer has not delivered an EBITDA Dispute Notice in accordance
with subparagraph (c) above, the amount required to be paid by Buyer pursuant to
Section 1.3 hereof shall bear interest, from May 1, 1999 until paid, at the rate
described in the previous sentence.

          (e) All payments required to be made in respect of the Earn-Out
Payment shall be made by cashier's check or wire transfer of immediately
available funds to an account designated by the payee.

          (f) For purposes of determining the Earn-Out, in the event that, prior
to January 1, 1999, Phoenix U.S. or Phoenix Canada (i) terminates any operation
of the


                                       -7-



Company or any Subsidiary, (ii) sells assets, except in the ordinary course of
business, of the Company or any Subsidiary or (iii) sells a controlling interest
in the Company or any Subsidiary or merges the Company or any Subsidiary with
any other Person (other than an Affiliate) (each such transaction an "Earn-Out
Restricted Transaction"), then the 1998 EBITDA shall equal (x) the annualized
1998 EBITDA for such business or assets sold (the "Divested Operations") based
on the 1998 EBITDA for the period beginning on January 1, 1998 through the last
day of the month prior to the closing of such Earn-Out Restricted Transaction
(the "Reference Period") PLUS (y) the 1998 EBITDA contributed by the remainder
of the Company and Subsidiaries.

     2.5. NET DEBT ADJUSTMENT.

          2.5.1. PRELIMINARY EARNED CASH CERTIFICATE. As soon as practicable and
in any event not later than five (5) business days prior to the U.S. Closing,
KAS will prepare and deliver to Phoenix U.S. a certificate setting forth the
Earned Cash of the Company and its Subsidiaries as of December 31, 1997 (or as
of the end of the month prior to the Closing Date if the Closing occurs after
January 31, 1998) (the "Preliminary Earned Cash"), and shall also include a
calculation of the Net Debt Amount as of December 31, 1997 (or as of the end of
the month prior to the Closing Date) (the "Preliminary Earned Cash
Certificate"). "Earned Cash" means at any particular date, the amount of cash
that would be on hand which is not subject to a corresponding liability,
determined in accordance with the Company's historical revenue recognition
policies as currently applied to each of the contracts of the Company and any
Subsidiary as set forth on SCHEDULE 3.6 (the "Company Policies") and equal to:
(x) the amount of cash reflected on the consolidated balance sheet of the
Company and its Subsidiaries minus the sum of (y) the amount of cash
representing customer deposits for services not yet performed by the Company or
a Subsidiary and (z) the amount of cash representing advanced payments of
reimbursable costs, with respect to which revenue should not be recognized other
than in accordance with the Company Policies.

          2.5.2. NET DEBT ADJUSTMENT. As soon as practicable following the
Closing Date, but not later than ninety (90) days thereafter, Ernst & Young LLP
(the "Buyers' Accountant") shall prepare and deliver a certificate proposing the
final amount of Earned Cash of the Company and its Subsidiaries as of the
Closing Date utilizing the Company Policies, and a calculation of the Net Debt
Amount as at such date (the "Earned Cash Certificate"). Deloitte & Touche LLP
(the "Sellers' Accountant") shall review the Final Earned Cash Certificate. In
the event Buyers' Accountant and Sellers' Accountant cannot agree on the final
amount of Earned Cash and the final Net Debt Amount the matter shall be
submitted to the EBITDA Arbitrator. The EBITDA Arbitrator shall review the
proposed Final Earned Cash Certificate and shall independently verify the
accuracy and completeness thereof and shall make such adjustments thereto as it,
in its independent judgment, believes appropriate to make such Final Earned Cash
Certificate fairly reflect the amount of Earned Cash available on the U.S.
Closing Date utilizing the Company Policies. If the Earned Cash as reflected on
the Earned Cash Certificate (agreed by the Sellers' Accountant and Buyers'
Accountant


                                       -8-



or determined by the EBITDA Arbitrator) is less than the Preliminary Earned
Cash, then KAS shall pay in cash to Phoenix U.S. the amount of the difference
(the "Net Debt Adjustment") which shall be treated as a reduction in the U.S.
Purchase Price. If the Earned Cash or the Final Earned Cash Certificate is more
than the amount of Earned Cash set forth on the Preliminary Earned Cash
Certificate, then Phoenix U.S. will pay in cash to KAS the amount of the
difference as additional U.S. Purchase Price. The payment, if any, to be made
under this Section 2.5.2 shall be made, without interest thereon, within five
(5) business days after delivery of the Final Earned Cash Certificate by the
Buyers' Accountant to the Parties. The fees and expenses of the Buyers'
Accountant in connection with the audit shall be paid by the Buyers, the fees
and expenses of the Sellers' Accountants shall be paid by the Sellers, and the
Buyers and Sellers shall each pay one half of the fees of the EBITDA Arbitrator.

Subsidiary has not incurred any Liability for any tax, excise tax, penalty or
fee with respect to any Employee Benefit Plan, and no event has occurred and no
circumstance exists or has existed that could give rise to any such Liability.

or Affiliates) or, after the Closings, use in any way any information that
relates to this Agreement, the Transactions or the Company and the Subsidiaries
(whether now possessed by the KAS or furnished by the Buyers after the Closing
Date), including, without limitation, all trade secrets, customer lists or other
customer information, marketing plans or proposals, financial information,
personnel information or any data, written material, records or documents used

provisions of this Article 9 are reasonable and necessary to protect the
interests of the Buyers, that any violation of this Article will result in an
irreparable injury to the Buyers and that damages at law would not be reasonable
or adequate compensation to the Buyers for violation of this Article. In the
event of any breach or threatened breach by KAS or any Affiliate thereof of any
provision of this Article 9, the Buyers shall be entitled to injunctive or other
equitable relief, restraining such party from using or disclosing any

provisions of this Article 9 specifically enforced by preliminary and permanent
injunctive relief without the necessity of proving actual damages or posting a

that the provisions of this Article 9 shall ever be deemed to exceed the time,
geographic, product or other limitations permitted by Applicable Law, then the
provisions shall be deemed reformed to the maximum extent permitted by
Applicable Law. KAS acknowledges,


                                      -41-



however, that this Article 9 has been negotiated by the Parties and that the
time, geographic and product limitations, as well as the limitation on
activities, are reasonable in light of the circumstances pertaining to the
Company and the Subsidiaries.

in this Agreement, all covenants, agreements, undertakings and indemnities set
forth in this Agreement shall survive indefinitely.

     10.2. INDEMNIFICATION BY KAS AND KURAYA. Subject to the provisions of
Section 10.3 and to the further provisions of this Section 10, KAS and Kuraya
shall, jointly and severally, indemnify each of the Buyer Indemnified Parties,
and hold them harmless from, against and in respect of, any and all Sellers'
General Liabilities. "Sellers' General Liabilities" shall mean all Losses
resulting from, arising out of, or incurred by the Buyers, the Company, any
Subsidiary or any of their respective successors or assigns and their respective
directors, officers and employees (each a "Buyer Indemnified Party") after the
Closing Date in connection with (i) any breach of any of the representations or
warranties made by the KAS or Kuraya in this Agreement, (ii) any Default by KAS,
Kuraya or IBRD-Rostrum in respect of any of the covenants or agreements made by
KAS, Kuraya or IBRD-Rostrum in this Agreement, (iii) any injuries to Persons,
property or business by


                                      -42-



reason of defectiveness of any services provided by or on behalf of, or 
business operations of, the Company or any Subsidiary, whether known or 
unknown, currently asserted or arising hereafter, if such claims are based 
upon or arise out of services performed or business operations on or prior to 
the Closing Date, provided that in the event of a Contract Claim (as 
hereinafter defined) such Claim is made within the applicable statute of 
limitations; such Losses for purposes of this Section 10.2(iii) shall be (A) 
"Contract Claims" if the gravamen of the action is based on breach of 
contract, or (B) "Tort Claims" if such Losses are not Contract Claims, (iv) 
any attempt by any Person to collect any Liability for Taxes relating to a 
period that ends on or before the Closing Date, or a Straddle Period (for 
which, in accord with the terms of Section 11.1(e) KAS is obligated to pay), 
including, without limitation, Taxes due under Treasury Regulation Section 
1.1502-6 (or any successor provision or any similar provision under state, 
local or foreign laws), provided such Claim is made within the applicable 
statute of limitations (as defined in Section 10.1 in respect of Taxes, 
except for (A) Taxes reserved for on the September Balance Sheet or incurred 
in the ordinary course of business from such date up to and including the 
Closing Date, (B) Taxes which the Buyers are required to pay pursuant to 
Sections 11.3 and 13.2 and (C) Taxes as to which disclosure is made in 
SCHEDULE 3.14 other than items set forth in SCHEDULE 10.2, (v) any 
Environmental Loss provided a Claim relating thereto is brought within the 
applicable statute of limitations, (vi) each item set forth in SCHEDULE 10.2 
hereof or (vii) costs incurred without corresponding contractual change 
orders to increase above the amount due thereunder on the date hereof revenue 
due under (A) Contract Research Organization Agreement (8/15/96) between 
Astra Merck Inc. and the Company (ASMUS 9602) and (B) Master Agreement 
(8/13/93) between the Company and Aviron (AVIRO 9506), to the extent such 
increased revenue on such contracts is less then $245,000 and $122,000, 
respectively.

     Notwithstanding the restrictions set forth in Section 9.1 hereof, in the
event Dainippon requests that the Company reperform any services in respect of
the Zonisamide study or NDA filing, the Buyers shall promptly notify KAS of such
request. KAS, subject to the consent of Dainippon and at KAS's and Kuraya's sole
expense, may elect to reperform such services, or cause such services to be
reperformed, which reperformance shall not constitute a breach of Section 9.1
hereof. Notwithstanding the preceding sentence, KAS and Kuraya shall pay,
perform and discharge all Liabilities, and shall indemnify any Buyer Indemnified
Party in respect of any Losses incurred by such Buyer Indemnified Party relating
to the Dainippon matter.

     10.3. LIMITATIONS ON OBLIGATION OF KAS AND KURAYA TO INDEMNIFY.

          (a) Except as otherwise provided in Section 10.1 with respect to
surviving provisions, KAS and Kuraya shall have no obligation to indemnify any
Buyer Indemnified Party pursuant to Section 10.2(i) above based solely upon any
breach by KAS or Kuraya of any representation or warranty as to which KAS or
Kuraya has not received a Claim Notice within eighteen months after the Closing
Date.


                                      -43-



          (b) Nothing herein shall be deemed to limit or restrict in any manner
any rights or remedies available at law, in equity or otherwise against KAS or
Kuraya based on a willful misrepresentation or willful breach of warranty by KAS
or Kuraya hereunder.

          (c) Notwithstanding anything to the contrary contained in this
Agreement, except as set forth below, KAS or Kuraya shall not have any Liability
for indemnification under Section 10.2(i), (ii) (except in respect of breaches
of representations, warranties or covenants affecting the determination of
Purchase Price or Net Debt Amount, which shall not be limited in any way) or
(iii) of this Agreement unless the aggregate of all Losses relating thereto for
which KAS and Kuraya would, but for this Section 10.3(c), be liable exceeds on a
cumulative and aggregate basis $250,000 (the "Threshold"), and then only to the
extent of such excess; provided, however, that such Threshold shall not apply to
any Losses attributable to or arising out of (1) an inaccuracy in any
representation or warranty set forth in (A) Section 3.14, 3.22, 3.23(b),
3.23(c), or (B) 3.13 or 3.23(a), in each case solely in connection with an
inaccuracy in any representation or warranty relating to an environmental matter
or (2) Section 10.2(iii) (in respect of Tort Claims), (iv), (v) and (vi) of this
Agreement, and, in the case of clauses (1) or (2) above the obligation of KAS
and Kuraya under Section 10.2 shall begin with the first dollar of loss;
further, provided that if but for the Loss giving rise to the indemnification
obligation under Section 10.2(i) or (ii), the Purchase Price or Net Debt Amount
would have been less, the Liability of the Sellers under Section 10.2(i) and
(ii) shall begin with the first dollar of Loss and should not be reduced or
otherwise affected by the Threshold.

          (d) Seller and Kuraya shall not be liable hereunder for any individual
Loss that is less than $5,000; provided, however, that all such Losses of or in
excess of $5,000 (from the first dollar of loss) shall be considered for
purposes of determining the Threshold.

          (e) Except for Losses indemnifiable under Section 10.2(iii) (in
respect of Tort Claims and Contract Claims), (iv) or (v), the maximum aggregate
amount of indemnifiable Losses that may be recovered by the Buyer Indemnified
Parties from KAS and Kuraya under this Article 10 shall not exceed $10,000,000.
The maximum aggregate amount of indemnifiable Losses under Section 10.2(iii) (in
respect of Tort Claims and Contract Claims), (iv) or (v) that may be recovered
by the Buyer Indemnified Parties from KAS and Kuraya under this Article 10 shall
not exceed the Purchase Price.

          (f) Subject to the limitation set forth in this Article 10, the amount
of any Losses for which indemnification by KAS or Kuraya is provided under
Article 10 of this Agreement shall be net of the amount of any insurance
proceeds actually recovered by a Buyer Indemnified Party pursuant to any
insurance policy in force and owned by the Company or any Subsidiary (the
"Insurance Proceeds"); provided, however, that notwithstanding this Section
10.3(f), any payment required under Article 10 shall accrue and become due and
payable in full as provided herein at the time such payment obligation arises
without taking into account any such Insurance


                                      -44-



Proceeds. In the event that Insurance Proceeds are actually recovered by a Buyer
Indemnified Party after payment by the indemnifying Party of any amount required
to be paid to a Buyer Indemnified Party under this Article 10, such Buyer
Indemnified Party shall repay to the indemnifying Party, promptly after such
recovery, any amount that the indemnifying Party would not have had to pay
pursuant to this Section 10.3(f) had such recovery been made to the Buyer
Indemnified Party at the time of the payment by the indemnifying Party.

          (g) Seller's and Kuraya's indemnities herein are intended solely for
the benefit of Buyer Indemnified Parties and are in no way intended to, nor
shall they, constitute an agreement for the benefit of, or be enforceable by,
any other Person.

          (h) Notwithstanding anything to the contrary in this Article 10, the
Buyers shall not be entitled to indemnification under Section 10.2 for any
Losses on account of the Company's or any Subsidiary's recognizing revenue for
periods on or prior to Closing for services to be performed by the Company or
its Subsidiaries after the Closing Date, except that the limitation of liability
in the preceding clause shall not apply for (i) any known material deviations to
the revenue recognition policy set forth in SCHEDULE 3.6, or (ii) Losses
relating to (A) the Contract Clinical Research Services Agreement dated 7/15/97
between Genetics Institute and IBRD-U.K.("GI Contract") and (B) Clinical
Development Agreement dated 4/29/96 between Bracco S.p.A. and IBRD-U.K. (Study
B16880/015) ("Bracco Contract").

     As soon as practicable after the Closing Date, but in any event, not later
than sixty (60) days after the Closing Date, the Buyers shall prepare and
deliver to the Sellers a certificate (the "Revenue Certificate") setting forth
their proposed calculation of Losses relating to the amount of revenue which was
recognized prior to the Closing Date in connection with the GI Contract and/or
Bracco Contract (the "Revenue Losses"). The amount of indemnifiable Loss shall
equal 76% of the Revenue Loss. The Sellers shall have thirty (30) days after
receipt of the proposed Revenue Loss Certificate to provide written notice to
Buyers if, and to the extent it disagrees with the proposed Revenue Losses set
forth in the Revenue Loss Certificate. If Sellers do not provide written notice
of a disagreement with the Revenue Loss Certificate, then the Revenue Losses set
forth therein shall be considered final, binding and conclusive on the Parties.
If Sellers provide a notice disputing the amount of Revenue Losses, then
Sellers' Accountant and Buyers' Accountant shall attempt to resolve the amount
of the Revenue Losses. If Sellers' Accountant and Buyers' Accountant are unable
to reach agreement after thirty (30) days of receipt by Buyers Accountant of the
written dispute notice, then the dispute shall be submitted to a nationally
recognized "Big Six" accounting firm or its successor (other than auditors used
by the Sellers or the Buyers or any Affiliate of either written the part three
(3) years, or their successors) chosen by lot (the "Third Accounting Firm")
which shall be instructed to arbitrate the disputed items and determine the
final Revenue Losses within thirty (30) days. The fees and expenses of the Third
Accounting Firm shall be borne equally by the Buyers and Sellers. The resolution
of disputes by the Third Accounting Firm shall be set forth in writing and shall
be conclusive and binding upon and non-appealable by the Parties


                                      -45-



and the determination of Revenue Losses shall become final upon the date of such
resolution, and may be entered as a final judgment in any court of proper
jurisdiction. KAS shall pay to Phoenix U.S. the final Revenue Losses within five
(5) days of the date of resolution. Amounts not paid when due shall bear
interest from the date due until paid at a rate equal to the lower of (i) the
Maximum Rate permitted by Applicable Law or (ii) two percent plus the prime rate
of the Bank of Canada on the date payment is due. Amounts of Revenue Losses
shall not be subject to the Threshold.

     10.4. INDEMNIFICATION BY THE BUYERS. Subject to the provisions of Section
10.5 and to the further provisions of this Section 10, Phoenix Canada and
Phoenix U.S. shall jointly and severally indemnify all Seller Indemnified
Parties, and hold them harmless from, against and in respect of, any and all the
Buyers' General Liabilities. "Buyers' General Liabilities" shall mean all Losses
resulting from, arising out of, or incurred by KAS or any of its Affiliates, or
any of their respective successors or assigns and their respective directors,
officers and employees (each a "Seller Indemnified Party") after the Closing
Date in connection with (i) any breach of any of the representations or
warranties made by the Buyers in this Agreement, (ii) any Default by the Buyers
in respect of any of the covenants or agreements made by the Buyers in this
Agreement, (iii) any attempt (whether or not successful) by any Person to cause
or require a Seller Indemnified Party to pay or discharge any liability of, or
claim against, the Buyers of any kind in respect of the operation of the Company
or any Subsidiary after the Closing Date to the extent not specifically subject
to an indemnity by the KAS under the terms of this Agreement, or (iv) any
liability under Section 500 of the California Corporations Code directly
resulting from liquidation distribution of the IBRD-Europe Purchase Price to
KAS.

     10.5. LIMITATIONS ON OBLIGATION OF THE BUYERS TO INDEMNIFY.

          (a) The Buyers shall have no obligation to indemnify any Seller
Indemnified Party based solely upon any breach by the Buyers of any
representation or warranty as to which the Buyers have not received a Claim
Notice within eighteen months after the Closing Date; provided, however, that
the representations and warranties of the Buyers under Section 4.5 shall survive
indefinitely and the representations and warranties of the Buyers under Sections
4.6 and 4.7 shall terminate at Closing.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, the Buyers shall not have any Liability for indemnification for
breaches of representations and warranties under this Agreement unless the
aggregate of all Losses relating thereto for which the Buyers would, but for
this Section 10.5(b), be liable exceeds on a cumulative and aggregate basis
$500,000 and then only to the extent of such excess, except for Sections
10.4(iv) and 11.3.

          (c) The maximum aggregate amount of indemnifiable Losses that may be
recovered by the Seller Indemnified Parties from the Buyers for breaches of
representations


                                      -46-



and warranties under this Article 10 shall not exceed $10,000,000, except for
Sections 10.4(iv) and 11.3.

     10.6. PROCEDURES FOR INDEMNIFICATION.

          (a) Each Indemnified Party shall promptly give notice hereunder (the
"Claim Notice") to the indemnifying Party and, to the extent applicable, in
accordance with the Escrow Agreement, after becoming aware of any claim as to
which recovery may be sought against the indemnifying Party because of the
indemnity provided in this Article 10 or otherwise in this Agreement. The
Indemnified Party shall provide the indemnifying Party with full and
unrestricted access to all books and records relating to the claim, and to all
employees or other persons who are knowledgeable about such claim, in order to
allow the indemnifying Party to audit the status of such claim and the payments
that have been or will be, made with respect thereto. After receiving such Claim
Notice, the indemnifying Party shall have thirty (30) days from the delivery of
the Claim Notice to notify the Indemnified Party that the indemnifying Party
will assume the defense of any such claim or any litigation resulting from such
claim; provided that if the period of time to respond, answer, defend or
otherwise plead to any claim or other item is less than such thirty (30) day
period, the Indemnified Party shall give prior notice to the indemnifying Party,
who shall have the right to so respond, defend, answer or otherwise plead by
giving timely notice to the Indemnified Party and if the indemnifying Party
fails to give such timely notice to the Indemnified Party, the Indemnified
Party, acting reasonably shall have the right to so respond, defend, answer or
otherwise plead to such claim. If the indemnifying Party assumes the defense of
the claim or litigation at issue, the Indemnified Party shall have the right to
employ separate counsel in such claim or litigation and to participate in the
defense or conduct thereof, but the fees and expenses of such counsel shall not
be at the expense of the indemnifying Party unless (i) the indemnifying party
shall have failed, within the time limits set forth in the preceding sentence,
to assume the defense of such claim or litigation, (ii) the employment of such
counsel has been specifically authorized in writing by the indemnifying Party,
(iii) the named parties to any such action (including any impleaded parties)
include both such Indemnified Party and the indemnifying Party and such
Indemnified Party and indemnifying Party shall have determined that there are
material conflicting interests between the indemnifying Party and the
Indemnified Party in the legal defense thereof and, in such event, each of legal
counsel selected by the indemnifying Party and the Indemnified Party shall be
required to cooperate fully with each other, (iv) the relief sought exceeds the
indemnifying Party's maximum indemnification obligations under Article 10
hereof, or (v) equitable relief is being sought against any Indemnified Party.
Notwithstanding the foregoing, the right to indemnification hereunder shall not
be affected by any failure of an Indemnified Party to give such Claim Notice (or
by delay by an Indemnified Party in giving such Claim Notice) unless, and then
only to the extent that, the rights and remedies of the indemnifying Party shall
have been prejudiced as a result of the failure to give, or delay in giving,
such Claim Notice. The Claim Notice required hereunder shall specify the basis
for the claim for indemnification to the extent ascertainable at the time of the
Claim Notice. If the matter to which a claim relates shall not have been
resolved as of the date of the Claim Notice, the Indemnified Party


                                      -47-



shall include an estimate of the amount of the claim in the Claim Notice to be
provided pursuant to this Section 10.6(a), accompanied by a statement therein
that the claim has not yet been liquidated (an "Unliquidated Claim"). In the
event that an Indemnified Party gives a Claim Notice for an Unliquidated Claim
relating to or arising from the breach of a representation or warranty prior to
the termination of the survival period of a representation or warranty set forth
in this Section 10, such survival period shall be tolled with respect to such
Unliquidated Claim until it becomes finally resolved pursuant to the provisions
of this Article 10. If an Indemnified Party gives a Claim Notice for an
Unliquidated Claim, the Indemnified Party shall also give a second Claim Notice
within thirty (30) days after the matter giving rise to the claim becomes
finally resolved, and such second Claim Notice shall specify the amount of the
claim.

          (b) Failure by the indemnifying Party to notify the Indemnified Party
of its election to defend any such claim or litigation by a third party within
thirty (30) days from the delivery of the Claim Notice to the indemnifying Party
shall be deemed a waiver by the indemnifying Party of its right to defend such
claim or litigation. If the indemnifying Party shall not assume the defense of
any such claim by a third party or litigation resulting therefrom, the
Indemnified Party may defend against such claim or litigation in such manner as
it may deem appropriate, acting reasonably, and may settle such claim of
litigation on such terms as it may deem appropriate, acting reasonably, without
prejudicing its rights against the indemnifying Party provided for herein. The
parties and their respective counsel shall provide reasonable cooperation and
information in connection with any claim or litigation as to which
indemnification is sought.

          (c) The indemnifying Party shall not, in the defense of such claim or
any Action resulting therefrom, consent to entry of any judgment (other than a
judgment of dismissal on the merits without costs) or enter into any settlement,
except with the written consent, which consent shall not be unreasonably
withheld, of the Indemnified Party, which does not include as an unconditional
term thereof the giving by the claimant or the plaintiff to the Indemnified
Party a release from all liability in respect of such claim or Action or which
would in any way restrict or impair the business of the Buyers, the Company, any
Subsidiary or any Affiliate of any of the foregoing.

          (d) If an indemnifying Party does not, within thirty (30) days after
its receipt of the Claim Notice required by Section 10.6(a) hereof or in
accordance with the Escrow Agreement or, in the case of an Unliquidated Claim,
within thirty (30) days after its receipt of the second Claim Notice described
in Section 10.6(a), advise the Indemnified Party that the indemnifying Party
denies the right of the Indemnified Party to indemnity in respect of the claim,
then the amount of such claim shall be deemed to be finally determined between
the Parties hereto. If the indemnifying Party notifies the Indemnified Party
that it disputes any claim made by the Indemnified Party, then the Parties
hereto shall endeavor to settle and compromise such claim, and if unable to
agree on any settlement or compromise, such claim for indemnification shall be
settled by appropriate arbitration in accordance with the terms of this
Agreement, and any Liability


                                      -48-



established by reason of such settlement, compromise or litigation shall be
deemed to be finally determined. Any claim that is finally determined in the
manner set forth above shall be paid promptly by the indemnifying Party in cash.

     10.7. PAYMENT OF INDEMNIFICATION OBLIGATIONS. Each Party shall pay promptly
to any Indemnified Party the amount of all Losses to which the foregoing
indemnity relates.

     10.8. INTEREST ON UNPAID OBLIGATIONS. If all or part of any indemnification
obligation under this Agreement is not paid when due, the indemnifying Party
shall pay the Indemnified Party interest on the unpaid amount of such obligation
for each day from the date the amount became due until it is paid in full,
payable on demand, at the rate equal to the lower of (i) the maximum rate
permitted by Applicable Law or (ii) two percent (2%) per annum plus the prime
rate of Bank of Canada.

     10.9. EXCLUSIVE REMEDY. Except as otherwise provided in this Agreement, the
provisions for indemnification set forth in this Article 10 are the exclusive
remedies of the parties hereto with respect to the matters addressed in this
Article 10, except for the remedies for injunctive relief provided elsewhere
herein and except for the indemnification obligations expressly provided
elsewhere in this Agreement and except as set forth in Section 10.3(b).


                                   ARTICLE 11

                                      TAXES

     11.1. FINAL TAX RETURN.

          (a) KAS will prepare the Federal consolidated income tax return for 
each taxable year (including any short taxable year) ending on or before the 
Closing Date (individually and in the aggregate, the "Final Return") that 
includes the Company (including IBRD-U.K.), IBRD-Rostrum and IBRD Center for 
Clinical Research, Inc. (the "IBRD Group") consistent with the consolidated 
return regulations promulgated pursuant to the Code and in a manner that is 
substantially similar to all prior KAS consolidated Federal income tax 
returns. In preparing the Final Return, (i) the allocation of tax items as 
between the last period covered by the Final Returns and the period 
commencing immediately after the end of such last period shall be made 
pursuant to the general Code method in accordance with Treasury Regulations 
Section 1.1502-76(b)(2)(i), and (ii) KAS shall not make any elections not 
made in prior returns nor shall it revoke any elections previously made, 
without the prior written consent of Phoenix U.S., which consent shall not be 
unreasonably withheld. KAS will present the draft Final Return to Phoenix 
U.S. 45 days prior to its filing due date (with extensions) for the review 
and approval of Phoenix U.S., which shall not be unreasonably withheld. 
Should Phoenix U.S. object to a reporting of an item or items of income, 
gain, loss,

                                      -49-



deduction or credit by sending written notice to KAS of such objection and the
reasons therefor within 10 business days of receipt of the draft Final Return
for review (the "Tax Notice"), the parties shall endeavor in good faith to reach
an acceptable reporting position. If such agreement cannot be reached within 10
business days after receipt by KAS of the Tax Notice, the issue shall be
reviewed and decided the Third Accounting Firm, taking into account the terms of
this Agreement. If the decision of the Third Accounting Firm is not received by
KAS by the day before the filing due date (with extensions) for the Final
Return, then the Final Return shall be filed in the manner determined by KAS,
and if the decision of the Third Accounting Firm requires a different action or
treatment in respect of any item on the Final Return then KAS shall file an
amended Final Return consistent with the decision of the Third Accounting Firm.
The fees of such Third Accounting firm shall be paid by Phoenix U.S. unless such
accounting firm determines that the Tax Notice is materially correct, in which
case, KAS shall bear such fees.

          (1) Without limiting the foregoing, KAS shall not make an election
     pursuant to Treasury Regulation Section 1.1502-20 of Section 1502 of the
     Code (or any other regulation or successor thereto) to reattribute to KAS
     any portion of the net operating loss carryover and net capital loss
     carryover attributable to any member of the IBRD Group.

          (2) Without the prior written consent of KAS, which consent shall not
     be unreasonably withheld, (i) a Buyer shall make no Code Section 338(g)
     election with respect to any IBRD-Europe Subsidiary.

          (3) Buyers and KAS acknowledge that the liquidation of IBRD-Rostrum
     and the sale of the IBRD-Europe Shares by the Company will be includible in
     the Final Return. Buyers agree not to cause the Company or any Subsidiary
     to take any action outside the ordinary course of business on either
     Closing Date (or to allow any such action to occur with respect to any
     IBRD-Europe Subsidiary once the Canadian Closing has occurred or with
     respect to the Company or any Subsidiary once the U.S. Closing has
     occurred), unless all Tax consequences of any such action shall be (i)
     reported under the "next day rule" of Treasury Regulations
     Section 1.1502-76(b)(1)(ii)(B) or (ii) if such rule is not applicable, 
     treated for all purposes as having occurred on the first day after the 
     Closings have occurred.

          (b) Buyers shall deliver to KAS any refund of Tax received by Buyers,
the Company or any Subsidiary after the Closing Date attributable to any Taxes
paid for any period ending on or before the Closing Date, and KAS shall deliver
to Buyers any refund of income Tax received by KAS, in its capacity as common
parent and agent of the Company and Subsidiaries, as a result of any carryback
of net operating loss or other similar item attributable to activities after the
U.S. Closing Date. KAS and the Buyers shall not have any obligation to seek any
such refunds but shall cooperate as reasonably required with the efforts of the
other to do so. Nothing in this


                                      -50-



Agreement shall require Buyer to incur any costs with respect to a refund that
will be delivered to KAS, and a refund that is derived or available because of a
payment between IBRD-U.K. and IBRD-Rostrum Global Limited with respect to Group
Relief, ACT or Taxation Refund, shall be retained by such Subsidiary and shall
not be deliverable to KAS.

          (c) All state and local Tax Returns for any member of the IBRD Group
not filed prior to the date of this Agreement for periods that end before or on
the U.S. Closing Date (the "Final State and Local Tax Returns") shall be
prepared by KAS in a manner consistent with the principles for preparation of
the Final Return set forth above and substantially similar to the same prior
state and local Tax Returns. KAS shall not make any elections not made in prior
returns nor shall it revoke any elections previously made, without the prior
written consent of Phoenix U.S., which consent shall not be unreasonably
withheld. Such Final State and Local Tax Returns shall be submitted to Phoenix
U.S. for review and approval, which shall not be unreasonably withheld, in the
same manner and subject to the same procedures as described in 11.1(a) above.

          (d) All non-U.S. tax returns for any of IBRD-Europe for periods that
end before or on the Canadian Closing Date, and which are due after such date
shall be completed by Phoenix Canada, or its agents. If any such returns are due
prior to the Closing of the Canadian Acquisition, they shall be prepared by the
relevant company. In either case, such Tax Returns shall be prepared in a manner
consistent with prior returns and the principles for preparation of the Final
Return set forth above, and the company shall allow Phoenix Canada or KAS, as
the case may be, to review and approve such returns prior to the filing, which
approval shall not be unreasonably withheld.

          (e) The Buyers shall, in accordance with Applicable Law, prepare or
cause to be prepared each Tax Return for the Company and each Subsidiary for any
period that includes but does not end upon the U.S. or Canada Closing Date as
applicable (such period the "Straddle Period," such Tax Return the "Straddle
Period Return"), in a manner consistent with prior such Tax Returns filed by or
on behalf of the Company and Subsidiaries. Except for (A) Taxes reserved for on
the September Balance Sheet or incurred in the ordinary course of business from
such date up to and including the Closing Date that have been accrued or
reserved for in the Books and Records of the Company or any Subsidiary, (B)
Taxes which Buyers are required to pay pursuant to Sections and 11.3 and 13.2
and (C) Taxes as to which disclosure is made in SCHEDULE 3.14 other than items
set forth in SCHEDULE 10.2, KAS shall pay the Taxes reported on a Straddle
Period Returns that are allocable to the portion of the Straddle Period ending
on the U.S. or Canada Closing Date. Such allocation of Taxes based on income
shall be done on the "closing of the books" basis; all other allocations of
Taxes shall be allocated based on the days in the Straddle Period. The Buyers
shall present the Straddle Period Return to KAS for review and approval, which
shall not be unreasonably withheld, in accord with the procedures set forth in
Section 11.1(a) above.


                                      -51-



     11.2. AUDITS AND TAX LITIGATION. KAS shall have control over any audit,
examination, appeal, and Tax Court or other Action relating to any Tax Return
required to be filed by KAS hereunder, and any Tax Return filed before Closing
with respect to which KAS or Kuraya may have Liability to a Buyer or any other
person under this Agreement or otherwise, and Buyers shall execute, verify,
acknowledge and deliver any and all powers of attorney and other documents and
instruments necessary for KAS to exercise such control; provided, however, that
Buyers shall have the right to participate in any such events, at Buyers'
expense, and provided further that KAS shall not enter into any settlement or
closing agreement with respect to Taxes without the prior written consent of
Buyers, which shall not be unreasonably withheld. Buyers shall have control over
any audit, examination, appeal, and Tax Court or other Action relating to any
Straddle Period Return or other Tax Return not filed by KAS that relates to any
Taxes for which KAS or Kuraya may have Liability to a Buyer or any other person
under this Agreement or otherwise; provided, however, that KAS shall have the
right to participate in any such events, at its expense solely as it relates to
an indemnifiable item, and provided further that Buyers shall not enter into any
settlement or closing agreement with respect to such item without the prior
written consent of KAS, which shall not be unreasonably withheld.

     11.3. TAX INDEMNITY. Without regard to any limitation expressed in Article
10, (i) Buyers shall, jointly and severally, indemnify KAS, and hold KAS
harmless from, against and in respect of, any and all Excess Tax Liabilities,
and Buyers shall pay to KAS the Gross-Up Amount with respect to any and all
Excess Tax Liabilities. "Excess Tax Liabilities"shall mean all Losses with
respect to Taxes incurred by KAS for Taxes as a result of the Transactions, to
the extent such Losses exceed the amount, if any, of the total liability for
Taxes that KAS would have incurred if the Transactions had been structured as a
sale by KAS of the IBRD-U.S. Shares for the Purchase Price instead of as (1)
first a sale by the Company of the IBRD-Europe Shares for the IBRD-Europe
Purchase Price and (2) then a sale by KAS of the IBRD-U.S. Shares for the
balance of the Purchase Price; provided, however, that Buyers shall have no
obligations under this Section 11.3 to the extent the Loss arose because the tax
basis of the IBRD-Europe Shares (as determined for federal or state purposes) to
the Company is, at the time of the Canadian Acquisition, less than $9,000,000 in
the aggregate. "Gross-Up Amount" shall the amount required to be paid to KAS
such that, after taking into account all Taxes incurred by KAS by reason of both
(i) indemnification of KAS in respect of the Excess Tax Liabilities and (ii) the
Gross-Up Amount, KAS shall have received a net amount after payment of such
Taxes equal to the Excess Tax Liabilities. Section 10.3(h) shall apply in
calculating the Losses under this paragraph, and nothing in this paragraph shall
be deemed to override Section 5.4.

          (f) at any time on or prior to the Closing Date, by mutual written
consent of KAS and the Buyers; or

hereof. None of the parties hereto shall have any liability in respect to a
termination of this Agreement pursuant to this Article 12, except to the extent
that failure to satisfy the conditions of Articles 7 or 8, as applicable,
results from the intentional or willful breach or violation of the
representations, warranties, covenants or agreements of such party under this
Agreement. For purposes of the preceding sentence, the failure of any party to
comply with its respective obligations under Article 1 promptly after all
conditions to such compliance shall have been fulfilled, shall constitute an
intentional or willful violation of the agreement herein contained by such
failing party.

     12.3. RETURN OF MATERIALS. If this Agreement is terminated for any reason
whatsoever, each party shall return to the other all documents, work papers and
other material (including all copies thereof) obtained in connection with the
transactions contemplated hereby and will use all reasonable efforts, including

access to such information, to keep confidential and not to use any such
information, unless such information is now, or is hereafter disclosed, through
no act or omission of such party, in any manner making it available to the

required by Applicable Law.

     13.13. SEVERABILITY. Whenever possible, each provision of this Agreement
and any Transaction Document shall be interpreted in such manner as to be

or invalidity without invalidating the remainder of such provision or the
remaining provisions of this Agreement or such Transaction Document.

     13.14. CONFIDENTIAL INFORMATION. The parties acknowledge that the
transactions described herein are of a confidential nature and shall not be

Affiliates, advisors and consultants in connection with the transactions
contemplated hereby or by any Transaction Document. KAS, at a time and in a
manner which reasonably determines and after prior notice to and consultation
with the Buyers, may notify employees of the Company and the Subsidiaries of the

each Subsidiary have been jointly represented by Sheppard, Mullin, Richter &
Hampton LLP in connection with this transaction and in other matters, and each

Subsidiary any and all conflicts of interest and privileges that may apply to
any future representation by such firm of KAS or its Affiliates in connection
with disputes arising from the transactions contemplated hereby or in connection
with any other matters.

     13.16. INJUNCTIVE RELIEF. The Buyers acknowledge that the provisions of
this Agreement or the Confidentiality Agreement requiring the Buyers (or any
Affiliate of the Buyers) to keep certain information confidential (the
"Confidentiality Provisions") are reasonable and


                                      -57-



necessary to protect the interests of KAS and Kuraya, that any violation of the
Confidentiality Provisions will result in an irreparable injury to KAS and
Kuraya and that damages at law would not be reasonable or adequate compensation
to KAS and Kuraya for such violation. Accordingly, in the event of any breach or
threatened breach by the Buyers (or any Affiliate of the Buyers) of the
Confidentiality Provisions, KAS and Kuraya shall be entitled to injunctive or
other equitable relief (from a Los Angeles County Court), restraining the Buyers
(or any Affiliate of the Buyers), as applicable, from engaging in conduct that
would constitute a breach of the Confidentiality Provisions. Such relief shall
be in addition to and not in lieu of any other remedies that may be available,
including an action for the recovery of damages. In addition to any other
available remedies, KAS and Kuraya shall be entitled to have the Confidentiality
Provisions specifically enforced by preliminary and permanent injunctive relief
without the necessity of proving actual damages or posting a bond or other
security and to an equitable accounting of all earnings, profits and other
benefits arising out of any violation of the Confidentiality Provisions.

     13.17. VENUE. The parties hereby agree that any action, suit arbitration or
other proceeding arising out of or related to this Agreement or any Transaction
Document or the relationship created hereby or thereby shall be conducted only
in Los Angeles County, California. Each party hereby irrevocably consents and
submits to the personal jurisdiction of and venue in United States District
Court for the Central District of California and in the Superior Court and
Municipal Court for Los Angeles County in any legal action, equitable suit or
other proceeding arising out of or related to this Agreement or any Transaction
Document, the negotiations thereof or the relationship between the parties
created hereby or thereby.

only by a written instrument signed by each of the parties hereto, in the case
of a waiver, by the party waiving compliance. The failure of a party to insist,
in any one or more instances, upon performance of the terms or conditions of
this Agreement shall not be construed as a waiver or relinquishment of any right
granted hereunder or of the future performance of any such term, covenant or
condition. No waiver on the part of any party of any right, power or privilege,
nor any single or partial exercise of any such right, power or privilege, shall
preclude any further exercise thereof or the exercise of any other such right,
power or privilege.

to the contrary, any controversy or claim arising out of or relating to this
Agreement or the breach thereof, other than a claim for specific performance or
injunctive relief, shall be settled by arbitration before a single arbitrator in
the State of California in accordance with the Commercial Arbitration Rules of
the American Arbitration Association, and judgment upon the award rendered by
the arbitrator may be entered in any court having jurisdiction thereof. All
costs associated with such arbitration shall be borne equally by the parties to
the dispute, except that each party shall bear the costs of its own attorneys
and experts (except as otherwise provided in this Agreement).

inure to the benefit of the parties and their respective permitted successors
and permitted assigns. Neither this Agreement nor any of the rights hereunder,
may be assigned by any party, nor may any party delegate any obligations
hereunder, without the written consent of the other party hereto or thereto. Any
non-permitted assignment or attempted assignment shall be void. Notwithstanding
the foregoing, any party hereto (other than the Escrow Agent) may assign this
Agreement, and


                                       -7-



any of its rights hereunder, and may delegate any of its obligations hereunder,
to any of its Affiliates.

       10.6 NO THIRD PARTY BENEFICIARIES. Nothing herein is intended or shall be
construed to give any person any legal or equitable right, remedy or claim under
or in respect of this Agreement or any provision contained herein, except as
otherwise provided herein.

       10.7 COUNTERPARTS. This Agreement may be executed by the parties in
separate counterparts, each of which when so executed and delivered shall be an

       10.8 HEADINGS. The heading herein are for reference only and shall not
affect the interpretation of this Agreement.

       10.9 SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
or invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity without invalidating the remainder of
such provision or the remaining provisions of this Agreement.
