each jurisdiction where the activities of the Partnership require such
qualification under applicable law, except where the failure to be so qualified
would not be materially adverse to the Partnership or its business.


                                  ARTICLE III.

                    CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS

          3.1.  Capital Contributions.  (a) Upon the formation of the
                ---------------------                                
Partnership under Israeli law, the General Partner shall make a Capital
Contribution to the Partnership in the amount of $40,000, and C.T.P. and PRI-
Research shall make Capital Contributions to the Partnership in the amounts of
$2,019,600 and $1,940,400, respectively.

          (b) The Partners shall make the following additional Capital
Contributions:

             (i) On the first anniversary of the date hereof, the General
     Partner shall make a Capital Contribution to the Partnership in the amount
     of $60,000, and C.T.P. and PRI-Research shall make Capital Contributions to
     the Partnership in the amounts of $3,029,400 and $2,910,600, respectively.

             (ii) On the second anniversary of the date hereof, the General
     Partner shall make a Capital Contribution to the Partnership in the amount
     of $50,000, and C.T.P. and PRI-Research shall make Capital Contributions to
     the Partnership in the amounts of $2,524,500 and $2,425,500, respectively.

          (c) All Capital Contributions pursuant to Section 3.1(b) hereof shall
be made in cash, unless the Partners shall unanimously agree otherwise.  In the
event that the Partners shall agree to accept loans from a Partner or a guaranty
of third-party debt by a Partner in lieu of Capital Contributions pursuant to
Section 3.1(b) hereof, such loans or guarantees shall be treated as Capital
Contributions for purposes of this Section 3.1 and, except as provided in
Section 3.3(a) hereof, for purposes of Section 3.2(b) hereof, but for no other
purposes of this Agreement.

                                       5

 
          (d) Notwithstanding anything herein to the contrary, the Partners
shall not be personally liable for the failure to make any Capital Contributions
specified in Section 3.1(b) hereof.  In the event of the failure of any Partner
to make all or any portion of any such Capital Contributions, the sole remedies
of the other Partners shall be as specified in Sections 3.2(b) and 3.3(a)
hereof.

          (e) No additional Capital Contributions, other than those required
pursuant to Sections 3.1(a) and (b) hereof, shall be made to the Partnership
without the unanimous written consent of the Partners.  Any such additional
Capital Contributions shall, unless otherwise agreed, be made in proportion to
the Partners' Sharing Percentages on the date thereof.

          3.2.  Sharing Percentages.  (a)  The initial Sharing Percentages of
                -------------------                                          
the Partners shall be as follows:  General Partner - 1.00%; C.T.P. - 50.49%; and
PRI-Research - 48.51%.

          (b) Upon any failure of a Limited Partner to make all or any portion
of any Capital Contributions specified in Section 3.1(b) hereof, the other
Limited Partner shall be entitled to make all or any portion of such unpaid
Capital Contributions on behalf of the first Limited Partner.  Simultaneously
with any Capital Contribution pursuant to Section 3.1(b) hereof or the first
sentence of this Section 3.2(b), the Sharing Percentages of the Limited Partners
shall be adjusted so that such Sharing Percentages shall be in proportion to the
aggregate Deemed Contributions of each of such Limited Partners.  For purposes
hereof, a Limited Partner's "Deemed Contributions" shall equal the sum of (i)
such Limited Partner's initial Capital Contributions pursuant to Section 3.1(a)
hereof, (ii) any Proportional Contributions (as defined in Section 3.2(c)
hereof) made by such Limited Partner, (iii) 200% of any Capital Contributions
described in Section 3.1(b)(i) hereof made by such Limited Partner (on behalf of
itself or on behalf of the other Limited Partner) to the extent such Capital
Contributions do not constitute Proportional Contributions, and (iv) 111% of any
additional Capital Contributions described in Section 3.1(b)(ii) hereof made by
such Limited Partner (on behalf of itself or on behalf of the other Limited
Partner) to the extent such Capital Contributions do not constitute Proportional
Contributions.  The General Partner's Sharing Percentage shall remain at 1.00%
throughout the term of the Partnership.

          (c) For purposes of this Section 3.2, a Limited Partner's Capital
Contributions shall be deemed to be "Proportional Contributions" only to the
extent that the other Limited Partner shall make a corresponding Capital
Contribution in proportion to its initial Sharing Percentage,

                                       6

 
as set forth in Section 3.2(a) hereof.  Capital Contributions pursuant to
Section 3.1(a) hereof shall not be treated as Proportional Contributions for
purposes of Section 3.2(b)(ii) hereof.

          (d) For purposes of illustration only, if, on the first anniversary of
the date hereof, C.T.P. shall make its entire required Capital Contribution of
$3,029,400, but PRI-Research shall make only $980,000 of its required Capital
Contribution of $2,910,600, only $1,020,000 ($980,000 x 50.49% / 48.51%) of
C.T.P.'s $3,029,400 Capital Contributions would constitute Proportional
Contributions.  In such a situation, the aggregate Deemed Contributions of
C.T.P. would be $7,058,400 ($2,019,600 + $1,020,000 + (200% x $2,009,400)) and
the aggregate Deemed Contributions of PRI-Research would be $2,920,400
($1,940,400 + $980,000), and their Sharing Percentages would be adjusted to
70.03% and 28.97%, respectively.

          3.3.  Partner Loans.  (a)  In the event that any Limited Partner (a
                -------------                                                
"Defaulting Partner") shall fail to make all or any portion of any additional
Capital Contributions described in Section 3.1(b) hereof, the other Limited
Partner, to the extent it shall not have made a Capital Contribution pursuant to
Section 3.2(b) hereof, shall be entitled to loan to the Partnership (i) all or
any portion of the Capital Contributions that were not made by the Defaulting
Partner, and (ii) all or any portion of its own required Capital Contributions
that would not constitute Proportional Contributions.  Any such loan shall be
payable by the Partnership out of any cash flow from operations or any available
refinancing proceeds and shall bear interest at one percentage point above the
Prime Lending Rate announced by Citibank, N.A. from time to time.
Notwithstanding the provisions of Section 3.1(c) hereof, any such loans shall
not be treated as Capital Contributions for purposes of Section 3.2(b) hereof;
provided, however, that a lending Partner who shall have made a loan pursuant to
- - - - --------  -------                                                               
this Section 3.3(a) shall be entitled, at any time, to convert all or any
portion of the principal amount of such loans to Capital Contributions for all
purposes of this Agreement (including for purposes of Section 3.2(b) hereof).
Any such conversion shall be effective on the date the Partnership and the
Defaulting Partner shall receive notice thereof.

          (b) Loans from the Partners to the Partnership (other than loans
described in Section 3.3(a) hereof) may be requested by the General Partner at
any time.  Such loans shall be on such terms as shall be agreed to by all the
Partners and shall be offered by the General Partner to the Partners in
proportion to their initial Sharing Percentages,

                                       7

 
as set forth in Section 3.1(a) hereof.  No Partner shall be required to make any
loans to the Partnership.

          3.4.  No Partition.  No Partner shall have the right to require
                ------------                                             
partition of the Partnership's property or to compel the sale of the
Partnership's assets or the dissolution of the Partnership.  Except as otherwise
specified herein, no Partner shall have the right to demand or receive cash or
other property for its Interest prior to the liquidation of the Partnership.  No
interest will be paid on any Partner's Capital Contributions or Capital Account.

          3.5.  Capital Accounts.  An individual Capital Account shall be
                ----------------                                         
established and maintained for each Partner in accordance with this Section 3.5.
Each Partner's Capital Account shall be credited with (i) such Partner's Capital
Contributions and (ii) the amount of Net Income allocated to such Partner
pursuant to Section 4.1(a) hereof.  Each such Capital Account shall be debited
with (i) the net fair market value of any property distributed to such Partner,
as determined hereunder; (ii) the amount of any cash distributions to such
Partner from the Partnership; and (iii) the amount of Net Loss allocated to such
Partner pursuant to Section 4.1(b) hereof.  Upon the transfer of any Interest,
the transferee shall receive the portion of the Capital Account of the
transferor attributable to the transferred Interest.

          3.6.  Grants.  The Partnership shall take all reasonable actions
                ------                                                    
necessary to solicit and obtain grants from governmental bodies inside and
outside Israel.  The General Partner shall seek to have the activities of the
Partnership classified as an "approved enterprise" by the Israeli Investment
Center, and to obtain grants from the Chief Scientist of the Israeli Ministry of
Industry and Trade.


                                  ARTICLE IV.

                         ALLOCATIONS AND DISTRIBUTIONS

          4.1.  Allocations of Net Income and Net Loss.  (a)  For accounting
                --------------------------------------                      
purposes, Net Income for each Fiscal Year shall be allocated as follows:

             (i) First, to the General Partner to the extent of the aggregate
     amount of Net Loss, if any, previously allocated to it pursuant to Section
     4.1(b)(iii) hereof which shall not have been offset by previous allocations
     of Net Income pursuant to this Section 4.1(a)(i);

             (ii) Next, among any Partners which shall have been allocated Net
     Loss pursuant to Section 4.1(b)(ii) hereof,

                                       8

 
     in proportion to, and to the extent of, the aggregate amount of such Net
     Loss previously allocated to each of them which shall not have been offset
     by previous allocations of Net Income pursuant to this Section 4.1(a)(ii);

             (iii)  Next, among any Partners which shall have been allocated Net
     Loss pursuant to Section 4.1(b)(i) hereof, in proportion to, and to the
     extent of, the aggregate amount of such Net Loss previously allocated to
     each of them which shall not have been offset by previous allocations of
     Net Income pursuant to this Section 4.1(a)(iii); and

          (iv) Thereafter, among the Partners in proportion to their respective
     Sharing Percentages.

          (b) Net Loss for each Fiscal Year shall be allocated as follows:

             (i) First, among the Partners in proportion to their respective
     initial Sharing Percentages set forth in Section 3.2(a) hereof until such
     allocation shall cause or increase a negative balance in any Limited
     Partner's Capital Account;

             (ii) Next, to the General Partner and any Limited Partner that
     shall not have a negative balance in its Capital Account, in proportion to
     their respective Sharing Percentages, until such allocation shall cause a
     negative balance in such Limited Partner's Capital Account; and

             (iii)  Thereafter, to the General Partner.

          (c) Each Partner's share of each item of the Partnership's income,
gain, deduction, loss or credit for Israeli and United States income tax
purposes shall be determined by the Partnership's accountants in accordance with
the laws of such jurisdictions based, as closely as possible, on the allocations
of Net Income and Net Loss contained herein.  In the event that the Partnership
shall incur any "Nonrecourse Liabilities" or "Partner Nonrecourse Debt", as such
terms are defined under the Treasury Regulations promulgated pursuant to Section
704 of the United States Internal Revenue Code of 1986, as amended, the Partners
shall amend the provisions of this Article IV to the extent necessary to allow
the Limited Partners to claim "Nonrecourse Deductions" and "Partner Nonrecourse
Deductions" for United States income tax purposes.

                                       9

 
          4.2.  Distributions.  (a)  Each Limited Partner may, at any time or
                -------------                                                
from time to time, by notice to the Partnership, request a distribution pursuant
to this Section 4.2(a) for the purpose of paying any additional taxes (including
estimated income tax payments) actually required to be paid within 45 days of
the date of such request by such Limited Partner (or its consolidated tax group)
with respect to any period in excess of the taxes that would have been due for
such period if such Limited Partner had not been a Partner in the Partnership.
Each such notice shall specify the type of tax and the amount (the "Tax
Distribution Amount") of any such additional taxes.  The General Partner shall
cause the Partnership to distribute the Tax Distribution Amount to such Limited
Partner, in cash, within thirty (30) days after any such distribution request.
Simultaneously therewith, the General Partner shall cause the Partnership to
distribute to each of the other Partners, an amount equal to the product of (i)
the Tax Distribution Amount, and (ii) the ratio of such other Partner's Sharing
Percentage to the Sharing Percentage of the Limited Partner that shall have
requested the tax distribution (determined as of the date such distribution
shall have been requested).

          (b) The General Partner shall cause the Partnership to distribute, in
cash, within sixty (60) days after the close of each Fiscal Year, in addition to
any distributions pursuant to Section 4.2(a) hereof, the amount of the
Partnership's Excess Cash.  For purposes hereof, the Partnership's "Excess Cash"
shall be determined as of the last day of each Fiscal Year and shall equal the
excess of (i) the amount of the Partnership's cash and cash equivalents on such
date, over (ii) the sum of (A) the amount of the Partnership's anticipated
future expenditures, as set forth in the budget described in Section 5.3(b)
hereof, and (B) the amount of reasonable reserves for anticipated expenses,
working capital, anticipated distributions pursuant to Section 4.2(a) hereof, or
repayment of Partnership borrowings, as determined in good faith by the General
Partner.  Any distributions pursuant to this Section 4.2(b) shall be made among
the Partners in proportion to their respective Sharing Percentages.

          (c) Notwithstanding Sections 4.2(a) and (b) above, upon dissolution of
the Partnership, all liquidating distributions shall be made in the manner
specified in Section 8.2 hereof.

          4.3.  Changes in Sharing Percentages.  In the event of any change in
                ------------------------------                                
the Partners' Sharing Percentages during any Fiscal Year, any Net Income or Net
Loss required to be allocated for such Fiscal Year in accordance with such
Sharing Percentages shall be allocated (a) for the portion of such Fiscal Year
through the close of the calendar quarter in which

                                       10

 
such change shall occur, on the basis of the average of the Partners' Sharing
Percentages as of the close of each calendar month during such period, and (b)
for the remainder of such Fiscal Year, in accordance with the Partners' new
Sharing Percentages.  In the event of such a change, any distributions pursuant
to Section 4.2(b) hereof with respect to such Fiscal Year shall be made among
the Partners in proportion to amounts of Net Income allocated to each of them
for such Fiscal Year (or, if there shall be no such Net Income, in proportion to
the Partners' Sharing Percentages on the last day of such Fiscal Year).

          4.4.  Tax Elections.  All matters concerning the allocation of tax
                -------------                                               
items among the Partners, tax elections under either Israeli or United States
law (except as may otherwise be required by either of such countries' income tax
laws) and accounting procedures not expressly and specifically provided for by
the terms of this Agreement shall be determined in good faith by the General
Partner, in consultation with the Partnership's accountants, on a basis which
shall be equitable among the Partners and such determination shall be final and
conclusive as to all of the Partners.

          4.5.  Withholding.  The Partnership shall have the right to deduct and
                -----------                                                     
withhold from any distributions hereunder, any taxes which the General Partner
shall determine in good faith are required to be withheld therefrom.  Any such
withholding taxes shall be charged to the Capital Account of the Partner on
whose behalf such taxes shall have been withheld.  In the event that the
Partnership shall be required to withhold any taxes on behalf of any Partner at
any time other than the time of a distribution, the amount of such withholding
shall be deemed to be a Tax Distribution Amount paid on behalf of such Partner
and the other Partners shall be entitled to a simultaneous distribution in
accordance with the last sentence of Section 4.2(a) hereof.

                 RIGHTS AND OBLIGATIONS OF THE LIMITED PARTNERS

          6.1.  No Participation in Management.  The Limited Partners shall have
                ------------------------------                                  
no right to control and shall take no part in the management or control of the

Partners under this Agreement.  The exercise of such rights and powers are
deemed to relate to material matters related to the business of the Partnership

                -----------------------------------                           
hereby represents and warrants to the other Partners and the Partnership as
follows:

              (i) It is a corporation duly organized, validly existing, and in
     good standing under the laws of the state of its formation.  It has all

     authorized and empowered to do so;

              (iii)  The execution and delivery of this Agreement and the
     consummation of the transactions as contemplated hereunder (A) do not, and
     will not, violate or conflict with any statute, regulation, judgment,
     order, writ, decree or injunction currently applicable to it or any of its

     the activities contemplated herein; and

              (v) It is not a party to or, to the best of its knowledge,

                                       15

 
     administrative proceeding that, if decided adversely to it, would delay or
     preclude the consummation of the transactions contemplated in this
     Agreement or have a material adverse effect upon the transactions
     contemplated hereby.

          (b) PRI-Research hereby represents and warrants to the Partnership and
the other Partners that all of its issued and outstanding shares of stock are
owned by PRI and that no options, warrants or other instruments which are
exercisable for, or convertible into, any shares of its capital stock have been

          (c) Each Limited Partner agrees to indemnify and hold harmless the
other Partners and the Partnership and their respective employees, agents and
Affiliates against all losses, liabilities, claims, damages, and expenses
(including, but not limited to, reasonable counsel fees) resulting from or
arising out of any actual or alleged misrepresentation or breach by such Limited

                                  ARTICLE VII.

                     TRANSFERABILITY OF INTERESTS; BUY/SELL

          7.1.  Transferability of Interests.  (a)  Except as provided in
                ----------------------------                             
Section 7.1(b) or Section 7.2 hereof, no Partner shall have the right to assign,
transfer, sell, encumber, pledge or otherwise dispose of all or any portion of
its Interest (a "Transfer") without the unanimous prior written consent of the
other Partners, which consent may be granted or withheld by each Partner in its
sole discretion.

          (b) Notwithstanding the provisions of Section 7.1(a) hereof, a Limited
Partner may Transfer its Interest, in whole or in part, to one or more majority-
owned subsidiaries, without obtaining the prior written consent of the other
Partners; provided, however, that such Transfer shall not release such Limited
          --------  -------                                                   
Partner from its obligations hereunder; and, provided, further, that, as a
                                             --------  -------            
condition to such Transfer,

                                       16

 
each such subsidiary shall agree to be bound by the terms of this Agreement.

          (c) Each Limited Partner agrees that it will, upon the request of the
General Partner, execute such certificates or other documents and perform such
acts as the General Partner shall deem appropriate to preserve the limited
liability of the Limited Partners under the laws of the jurisdictions in which
the Partnership is doing business after any Transfer by that Limited Partner.
Any purported Transfer in violation of the provisions of this Section 7.1 shall
be null and void and shall not bind, or be recognized by, the Partnership.

          (d) Each Partner and each assignee thereof shall indemnify and hold
harmless the Partnership, every other Partner and any Affiliate of the foregoing
(each, an "Indemnified Person") against all losses, claims, damages,
liabilities, costs and expenses (including reasonable counsel fees), joint or
several, to which such Indemnified Persons may become subject by reason of or
arising from any Transfer made by such Limited Partner in violation of this
Section 7.1.

          7.2.  Buy/Sell.  (a) Either Limited Partner may elect to institute the
                --------                                                        
Buy/Sell Procedure at any time after the third anniversary of the date hereof.
Notwithstanding the foregoing, C.T.P. shall be entitled to institute the
Buy/Sell Procedure at any time within two years after the occurrence of a "Third
Party Transaction", as defined in Section 10.1(c) of the SPA, and PRI-Research
shall not be entitled to institute the Buy/Sell Procedure during any period that
C.T.P. or its Affiliates shall have a right to require PRI or any successors
thereto to acquire C.T.P.'s Interest as a result of such a Third Party
Transaction, pursuant to any effective agreement between PRI and CPI or their
Affiliates.

          (b) In order to institute the Buy/Sell Procedure, a Limited Partner
(the "Offeror") shall send the other Limited Partner (the "Offeree") a written
notice (the "Buy/Sell Notice") specifying a value for the Partnership, net of
liabilities (the "Net Value").  The Buy/Sell Notice shall contain an
unconditional offer by the Offeror to either (i) purchase the entire Interest of
the Offeree, together with all of the stock owned by the Offeree and its
Affiliates in the General Partner, at the Offeree's Deemed Liquidation Value, or
(ii) sell its entire Interest, together with all of the stock owned by it and
its Affiliates in the General Partner, to the Offeree at the Offeror's Deemed
Liquidation Value.  For purposes hereof, a Limited Partner's "Deemed Liquidation
Value" shall equal the sum of (A) the amount such Limited Partner would have
received in respect of its Interest had the Partnership been liquidated and the
Net Value been distributed

                                       17

 
in cash in accordance with Section 8.2(b)(iv) hereof, plus (B) the product of
(1) the amount the General Partner would have received in respect of its
Interest had the Partnership been liquidated and the Net Value been distributed
in cash in accordance with Section 8.2(b)(iv) hereof, and (2) the percentage of
the General Partner's stock owned by such Limited Partner and its Affiliates.

          (c) The Offeree shall have 60 days after its receipt of the Buy/Sell
Notice to accept the offer described in either clause (i) or clause (ii) of
Section 7.2(b) hereof.  If the Offeree shall not notify the Offeror, in writing,
within such 60-day period that it shall have elected to accept the offer
described in clause (ii) of such Section 7.2(b), the Offeree shall be
conclusively deemed to have accepted the offer described in clause (i) thereof.

          (d) The closing of the purchase and sale of a Limited Partner's
Interest and its (or its Affiliates') stock in the General Partner shall occur
on a date designated by the Limited Partner purchasing such Interest and stock
(the "Purchaser"), which date shall be no later than 120 days after the date of
the Buy/Sell Notice.  On the date of such closing, the Purchaser shall deliver
the purchase price determined pursuant to Section 7.2(b) hereof to the Limited
Partner selling its Interest (the "Seller"), in cash.  In connection therewith,
the Seller shall execute such documents as shall be necessary to convey its
Interest to the Purchaser; and the Seller and/or its Affiliates shall deliver
certificates representing all shares of stock owned by them in the General
Partner to the Purchaser.  The Interest and any stock in the General Partner
sold to the Purchaser shall be conveyed free and clear of any liens, charges or
encumbrances thereon (other than liens, charges or encumbrances placed thereon
as a result of borrowings by the Partnership or the General Partner).

          (e) The Seller shall not solicit any employees of the Partnership or
the General Partner (other than persons who are or were previously also
employees of the Seller or its Affiliates) for a period of two years after the
closing of any purchase and sale pursuant to the Buy/Sell Procedure.  For
purposes of the preceding sentence, the term "Affiliates" shall not include the
Partnership or the General Partner.
 
          7.3.  Withdrawals of Partners.  No Partner shall withdraw from the
                -----------------------                                     
Partnership prior to the Partnership's dissolution except in connection with a
transfer of such Partner's entire Interest pursuant to this Article VII.

                                 ARTICLE VIII.

          DISSOLUTION, LIQUIDATION AND TERMINATION OF THE PARTNERSHIP

          8.1.  Dissolution.  The Partnership shall be dissolved upon the
                -----------                                               
happening of any of the following events:  (a)  the expiration of its term; (b)
the election of all the Partners to dissolve the Partnership; (c) the
adjudication of bankruptcy of the Partnership; (d) the dissolution or
adjudication of bankruptcy of the General Partner unless, within 90 days
thereafter, Limited Partners holding at least 65% of the Sharing Percentages and
65% of the aggregate Capital Account balances on the date of the General
Partner's dissolution or adjudication of bankruptcy, shall agree to continue the
business of the Partnership and appoint a new General Partner; (e) the sale of
all or substantially all of the assets of the Partnership for cash; and (f) any
dissolution required by operation of law.

          8.2.  Liquidation.  (a)  Upon dissolution of the Partnership, the
                -----------                                                
General Partner or a liquidator appointed by the General Partner shall wind up
the affairs of the Partnership and liquidate its assets.

          (b) As soon as practicable after the date of dissolution of the
Partnership, the Partnership's assets shall be distributed in the following
manner and order:

              (i) the claims of all creditors of the Partnership who are not
     Partners shall be paid and discharged or adequately reserved against;

              (ii) the claims of the Partners as creditors of the Partnership
     shall be paid and discharged or adequately reserved against;

              (iii)  the expenses of dissolution and winding up shall be paid
     and discharged or adequately reserved against; and

              (iv) the remaining assets of the Partnership shall be distributed
     to the Partners, in cash or in kind, in the manner set forth in Section
     8.2(c) hereof, in accordance with the Capital Accounts of the Partners.

          (c) In connection with the liquidation of the Partnership, PRI-
Research shall have the first option to receive all or any portion of any assets
of the Partnership relating to the Partnership's operations in the Americas
(including, without limitation, future revenues, intellectual property,
trademarks, permits, ANDAs, NDAs, manufacturing and

                                       19

 
distribution rights and any tangible assets physically located in the Americas
on the date of dissolution) as a liquidating distribution, and C.T.P. shall have
the first option to receive all or any portion of any other assets of the
Partnership, including, without limitation, the Israeli plant and equipment, as
a liquidating distribution.  In the event that a Limited Partner shall elect not
to exercise such option with respect to any asset within 30 days after the
effective date of the Partnership's dissolution, the other Limited Partner shall
be granted the option, exercisable at any time within 30 days after the
expiration of the first Limited Partner's option, to receive such asset as a
liquidating distribution.  The Limited Partners shall cooperate with respect to
the development of any products under development by the Partnership on the date
of such dissolution; all rights to manufacture and distribute in the Americas
any such products shall be granted to PRI-Research, and all rights to
manufacture and distribute any such products outside the Americas shall be
granted to C.T.P.  Any other assets of the Partnership shall be sold to third
parties as part of the liquidation process or distributed to a liquidating trust
for the benefit of the Partners.  The fair market value of any assets
distributed to any Limited Partner pursuant to this Section 8.2(c) shall be
determined by an independent appraiser mutually acceptable to the Limited
Partners and shall be applied against such Limited Partner's final Capital
Account balance for purposes of Section 8.2(b)(iv) hereof.  In the event that
the fair market value of the assets distributable to any Limited Partner
pursuant to this Section 8.2(c) shall exceed such Limited Partner's final
Capital Account balance, such Limited Partner shall make a cash Capital
Contribution to the Partnership in the amount of such excess.  In the event that
the final Capital Account balance of a Limited Partner shall exceed the fair
market value of any assets distributable to such Limited Partner pursuant to
this Section 8.2(c), such excess shall be distributed to such Limited Partner in
cash.  The General Partner's final Capital Account balance shall be distributed
to it in cash.  In the event that the foregoing order of distribution shall not
be permitted under the Partnership Act, distributions shall be made as closely
as legally possible to the order of distribution required hereby.

          (d) In the event the General Partner shall have a deficit balance in
its Capital Account following the liquidation of the Partnership or its
Interest, after taking into account all adjustments to such Capital Account for
the Fiscal Year in which such liquidation occurs, it shall be unconditionally
obligated to restore the amount of such deficit to the Partnership, as a Capital
Contribution, by the end of such Fiscal Year (or, if later, within 90 days of
the final date of such liquidation).  No Limited Partner with a deficit balance
in its Capital Account shall be required to

                                       20

 
restore the amount of such deficit balance to the Partnership upon liquidation
of the Partnership or such Limited Partner's Interest therein.

          (e) If there shall be any pending transaction or claim by or against
the Partnership as to which the interest or obligation of any Partner therein
cannot, in the judgment of the General Partner or the liquidator, be then
ascertained, the value thereof or probable loss therefrom may be excluded from
the valuation of assets for purposes of computing such Partner's Capital Account
upon liquidation.  No amount shall be paid or charged to any such Partner's
Capital Account in respect of any such transaction or claim until its final
settlement or such earlier time as the General Partner or the liquidator shall
determine.  Moreover, the Partnership may retain from any sums due any such
Partner an amount which the General Partner or the liquidator shall estimate to
be sufficient to cover the share of such Partner in any probable loss or
liability on account of such transaction or claim.  The General Partner or the
liquidator shall, at the earliest practicable time, distribute any assets (or
proceeds realized from the sale thereof) excluded or retained pursuant to this
Section 8.2(e) to each Partner from whom such assets or proceeds shall have been
withheld.

          8.3.  Incorporation of the Partnership.  The Partners shall review the
                --------------------------------                                
structure of the Partnership as a limited liability partnership under Israeli
law upon the request of any Partner.  In the event that any Partner shall
request that the Partnership (a) be converted into a corporation or other form
of entity or (b) organize a corporate subsidiary to conduct all or any part of
the Partnership's operations, such conversion, or the formation of such
subsidiary, shall be effectuated on terms acceptable to all the Partners if the
prior written consent of each other Partner thereto shall have been obtained.
No Partner shall unreasonably withhold its consent to any request to convert the
Partnership into another entity or to organize such a corporate subsidiary;
provided, however, that a Partner shall not be deemed to have unreasonably
- - - - --------  -------                                                         
withheld its consent to such a conversion or organization of a subsidiary if it
shall obtain an opinion of its counsel that such conversion or organization of a
subsidiary would have a reasonable possibility of resulting in significant
adverse tax or regulatory consequences to such Partner or the Partnership.

books of account of the business of the Partnership shall be maintained by the
General Partner at the Partnership's principal place of business, and each
Limited Partner or its duly authorized representative shall have access to them,
upon reasonable notice and for a proper purpose, at all reasonable times during
business hours.

          (b) The books and records of the Partnership shall be kept on the
basis of accounting determined by the General Partner.  The financial statements
of the Partnership shall be prepared on a monthly basis in accordance with
Israeli generally accepted accounting principles consistently applied
denominated in NIS and restated to the general purchasing power of the Israeli
currency, and shall be appropriate and adequate for the Partnership's business
and for carrying out all provisions of this Agreement.  In addition, similar
financial statements prepared in accordance with United States generally
accepted accounting principles consistently applied and denominated in U.S.
Dollars shall be prepared and furnished to PRI-Research, at the expense of the
Partnership, at each time Israeli financial statements shall be prepared.  In
the event of any conflict between the Partnership's Israeli and United States
financial statements, the Israeli financial statements shall be controlling.
The Fiscal Year of the Partnership shall end on December 31.

          9.2.  Tax Information.  Within 60 days after the end of each Fiscal
                ---------------                                              
Year, the General Partner will cause to be delivered to each Person who was a
Partner at any time during such Fiscal Year all information necessary for the
preparation of such Partner's income tax returns in Israel, the United States
and any other jurisdiction (federal, state or local) in which a Partner shall be
required to file an income tax return as a result of the Partnership's
operations.  The Partnership shall, if required under the United States tax
laws, file an annual partnership return of income in the United States on Form
1065 (or any successor form) in accordance with all applicable requirements of
such United States tax laws.

          9.3.  Financial Reporting.  The Partnership shall provide each
                -------------------                                     
Partner, in a timely manner, such information which such Partner's auditors
shall require in order to comply with any applicable laws, regulations or
guidelines in Israel or the United States.  The Partnership shall be audited as
of the Saturday closest to September 30 in each Fiscal Year, and as of such
other dates as shall be requested by any Partner.

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

          10.9.  Counterparts.  This Agreement may be executed in several
                 ------------                                            
counterparts, each of which shall be deemed an original but all of which shall

          10.10. Further Assurances.  Each of the Partners hereby agrees that it
                 ------------------                                             
shall do and perform, or cause to be done and performed, all such further acts
and things and shall execute and deliver all such other agreements,
certificates, instruments and documents as any other Partner may reasonably
request in order to carry out the intent and accomplish the purposes of this
Agreement and the consummation of the transactions contemplated hereby.

          10.11. Arbitration.  Any disagreement or dispute among the Partners
                 -----------                                                 
arising hereunder or in connection with the transactions hereunder shall be
resolved by arbitration by a single arbitrator.  The arbitration shall be held
in Tel Aviv and shall be conducted in the English language, in accordance with
the Israel Arbitration Law - 1968; provided, however, that if the provisions of
                                   --------  -------

and binding upon the parties, and judgment upon the arbitral award may be
entered by any court of competent jurisdiction.  Unless the arbitrator shall
otherwise determine, the parties shall bear equally the fees and expenses of the
arbitrator.  Each of the parties shall bear its own expenses in connection with
the arbitration, but in the event that court proceedings are instituted in
connection with this Agreement or in connection with any arbitration hereunder,
the party prevailing in such proceedings shall be entitled to recover its
reasonable attorneys' fees and expenses.  This provision shall be deemed to be
an arbitration agreement for the purposes of the Israel Arbitration Law.

          10.12. Announcements and Publications.  The Partners shall consult
                 ------------------------------                             
with each other, to the extent practicable, as to the form and substance of any
press releases and other third party communications or disclosures relating to
this Agreement or any of the transactions contemplated hereby.  No Partner (or
Affiliate thereof) shall be prohibited from issuing or filing any press release
or other third party communication or disclosure which, upon advice of its legal
counsel, shall be deemed necessary or required under applicable law or the
applicable rules of any stock exchange, provided that such Partner shall have
first consulted with the other Partners as to the form and content of such
disclosure.
