     WHEREAS  Genpharm and its Affiliates (as hereafter  defined) are engaged in

submission of abbreviated new drug applications) for certain of the Products (as
hereafter defined);

     AND  WHEREAS,  as between  Genpharm  and its  Affiliates,  Genpharm has the
exclusive right to supply, market and distribute such Products in North America,
which right permits Genpharm to appoint distributors, exclusive or otherwise, in
respect  of all or any of the  Products  for  the  whole  or any  part  of  such
territory;

     AND  WHEREAS  Resources  and its  Affiliate  are  engaged  in,  inter alia,
manufacturing,   marketing  and  distributing  generic  pharmaceutical  products
throughout the Territory (as hereafter defined) and own and operate FDA approved
manufacturing  facilities  and  possess  qualified  marketing  and  distribution
systems  and   organizations  to  enable  it  to  repackage  bulk  Products  and
effectively  promote,   market  and  distribute  such  Products  throughout  the
Territory;

     AND WHEREAS  Genpharm  desires to grant to Resources the exclusive right to
purchase,  market,  promote and  distribute  the Products in the  Territory  and

     AND  WHEREAS  the parties  wish to enter into this  agreement  to set forth
herein the arrangements  regarding their respective  rights and obligations with
respect  to  the  development,  registration,  supply  and  distribution  of the
Products for the Territory;

     NOW THEREFORE the parties hereto agree as follows:

                                    ARTICLE 2
                              EXCLUSIVE APPOINTMENT

2.1 Exclusive  Distributor:  Subject to the  provisions of this agreement and to
the  receipt  by  Genpharm  or its  Affiliate,  as the case may be, of a Product
Approval for such Product,  Genpharm hereby  appoints  Resources as the sole and
exclusive  distributor  of the Products for the Territory  and Resources  hereby
accepts such  appointment and agrees to act as such sole  distributor  upon such
terms and  conditions.  Except  for its right to  delegate  to an  Affiliate  of
Resources any duty,  obligation  or right  hereunder in relation to a Product in
accordance  with the  provisions  of Section 14.8 below (but only for so long as
such Person remains an Affiliate of Resources),  Resources shall not delegate to
any Person any duty or  obligation  of  Resources  hereunder  in  relation  to a
Product  without the prior  written  consent of Genpharm  (which  consent may be
withheld in the sole discretion of Genpharm).

2.2 Additional  Products:  The parties may, by mutual  agreement,  add any other
generic  pharmaceutical  product to or delete a Product from this agreement and,
in such event,  the parties  shall date and initial such  alteration on Schedule
"B" for purposes of  identification  and  thereafter the terms of this agreement
shall  govern  the  products  so added and shall  terminate  in  respect  of the
products so deleted  (except to the extent of continuing  obligations  following
termination as hereinafter contemplated).  The foregoing right to terminate this
agreement  as regards a specific  Product by mutual  agreement is in addition to
and not in  substitution  or  derogation  of any right of a party  hereunder  to
unilaterally terminate this agreement as regards any Product pursuant to Section
3.4 or 3.7 or Article  10  hereof.  The  foregoing  right to add any  product by
mutual  agreement to Schedule "B" is in addition to and not in  substitution  or
derogation of the rights and  obligations  contemplated  in Sections 3.4 or 3.10
hereof.

2.3 Nature of  Relationship:  This  agreement does not constitute or create (and
the  parties  do  not  intend  to  create  hereby)  a  joint  venture,   pooling
arrangement,  partnership,  or formal business  organization of any kind between
and among any of the  parties,  and the rights and  obligations  of the  parties
shall  be only  those  expressly  set  forth  herein.  The  relationship  hereby
established  between  Resources and Genpharm is solely that of buyer and seller,
each is an independent contractor engaged in the operation of its own respective
business.  Neither party shall be considered to be an agent of the other for any
purpose  whatsoever.  Each party  shall be  responsible  for  providing  its own
personnel and workers'  compensation,  medical coverage or similar benefits, any
life, disability or other insurance protection;  and shall be solely responsible

                                       2


for the payment of social security  benefits,  unemployment  insurance,  pension
benefits,    withholding   any   required   amounts   for   income   and   other
employment-related  taxes and benefits of its own employees,  and shall make its
own  arrangements  for injury,  illness or other  insurance  coverage to protect
itself; its Affiliates,  its subcontractors and personnel from any damages, loss
and/or liability arising out of the performance of this agreement. Neither party
has the  power or  authority  to act for,  represent,  or bind the other (or its
Affiliates) in any manner.

2.4 Territorial  and Product  Restrictions  Applicable to Resources:  During the
term of this agreement  applicable to a Product neither Resources nor any of its
Affiliates  will  directly  or  indirectly  sell  such  Product  outside  of the
Territory  or to any  Person in the  Territory  where it knows or has  reason to
believe  that  such  Product  will be  resold  by  such  Person  outside  of the
Territory.  In the event the foregoing provision is or becomes  unenforceable or
is  unlawful  in the  Territory,  then it shall be deemed  replaced  by the most
restrictive  provision  on  marketing  or sale  of the  Product  outside  of the
Territory  as shall be lawful and  enforceable  in the  Territory.  If  Genpharm
establishes  that  one  of  Resources'  customers  or a  customer  of any of its
Affiliates is exporting such Product out of the Territory,  Resources shall (and
shall cause its  Affiliates  to) either cease to supply such  customer or obtain
(and enforce,  if necessary) an  undertaking  from such customer not to sell the
Product  outside of the Territory  (unless  Resources [or its Affiliate,  as the
case may be] is precluded  from taking such action  under  applicable  law).  In
addition,  Resources shall not (and it shall not authorize, permit or suffer any
of its Affiliates to), directly or indirectly,  manufacture,  purchase,  sell or
distribute a Competing  Product in the  Territory at any time during the term of
this agreement applicable to a Product (including,  for greater certainty, prior
to receipt by Genpharm or any of its  Affiliate  of a Product  Approval for such
Product).

2.5 Product  Restrictions  Applicable to Genpharm:  Genpharm agrees that, during
the term of this  agreement  applicable to a Product,  neither it nor any of its
Affiliates shall, directly or indirectly,  sell such Product in the Territory or
to any Person  outside of the Territory  where it knows or has reason to believe
that such Product will be resold by such Person in the  Territory.  In the event
the foregoing provision is or becomes unenforceable or unlawful in the Territory
it shall be deemed to be replaced by the most restrictive provision on marketing
or sale of the Product in the Territory as shall be lawful or enforceable in the
Territory.  If  Resources  notifies  Genpharm  that one of its  customers  (or a
customer of its Affiliate) is marketing the Product in the  Territory,  Genpharm
shall (and shall cause its  Affiliates  to) either cease to supply such customer
or obtain (and enforce if  necessary) an  undertaking  from such customer not to
market such Product in the Territory (unless Genpharm [or its Affiliate,  as the
case may be] is  precluded  from  taking  such  action  under  applicable  law).
Genpharm  further  agrees that,  so long as Merck KGaA and its  Affiliates  hold
collectively at least 33-1/3% of the issued and outstanding shares of Resources'
common stock,  neither  Genpharm nor any of its Affiliates will sell,  market or
distribute  in the Territory  any generic  pharmaceutical  product which has the
same active  ingredient,  same strengths,  is in the same dosage form and is for
the same indication as a generic  pharmaceutical  product currently marketed and
distributed  by Resources  and its  Affiliates  in the Territory as described in
Schedule "C" annexed  hereto so long as Resources or any of its  Affiliates  are
actively  marketing  and selling such Product in the  Territory;  provided  that
where a product  identified on Schedule "C" is one in respect of which  Genpharm
or any of its  Affiliates  holds the ANDA approval and is being  distributed  by
Resources  and its  Affiliates in the  Territory  pursuant to an agreement  with
Genpharm or any of its Affiliates then Genpharm and its Affiliates shall be free
to sell, market and distribute such product in the Territory at such time as its
agreement  with  Resources  and its  Affiliates  terminates  in  respect of such
product or Resources  and/or its Affiliates'  exclusive right to distribute such


                                       3


product  by or on  behalf  of  Genpharm  and  its  Affiliates  pursuant  to such
agreement is terminated in accordance with the provisions thereof.



                                    ARTICLE 3
                      PRODUCT DEVELOPMENT AND REGISTRATION


3.1 Obligations to Develop and Register Products:  Subject to Section 3.4 below,
Genpharm  shall, or shall cause its Affiliates to, use  commercially  reasonable
best efforts to develop the Products for the Territory in such order of priority
as is determined  by Genpharm and to submit ANDA's to the FDA to obtain  Product
Approvals  for  such  Products  as  soon  as  reasonably  practicable  following
successful  development,  provided  that Genpharm  shall have the right,  in its
discretion, to alter the priority to be given to development and/or registration
of the Products and nothing  herein  contained  shall  constitute a guarantee or
warranty of  Genpharm  that  development  of any Product  will be  commenced  or
continued,  that a  submission  for a Product  Approval for such Product will be
filed within any specific time period or that a Product Approval for any Product
will be obtained. Notwithstanding the foregoing, Genpharm and its Affiliate may,
at their  option,  in lieu of  independently  developing a Product  (directly or
through any other Affiliate) obtain a licence of the Product  Information of any
Person who is not an Affiliate of Merck KGaA (the "Third  Party  Licensor")  and
submit an ANDA for such Product based upon such licenced Product Information. It
is  understood  and agreed by  Resources  that where  Genpharm or its  Affiliate
licences its Product  Information  for a Product from a Third Party  Licensor it
may  be  required  to pay to  the  Third  Party  Licensor  a  royalty  or  other
compensation  (including,  without limitation,  profit sharing) for its right to
use such  Product  Information  (the  "Third  Party  Royalty").  Genpharm  shall
hereafter advise Resources of its intention or the intention of its Affiliate to
licence any Product  Information in relation to a Product for the Territory from
a Third Party Licensor and shall consult with  Resources  prior to entering into
any agreement with such Third Party Licensor to licence such Product Information
so that  Resources  shall be fully  informed  as to the nature and terms of such
relationship.


3.2  Development  Responsibility:  Subject to Section 3.4 below, it shall be the
responsibility   of  Genpharm  and/or  its  Affiliates,   (i)  to  complete  the
development of the Products in accordance  with the applicable  requirements  of
the FDA, (ii) where such development has been successfully completed, to file an
ANDA for the Product with the FDA and,  (iii) where an ANDA for such Product has
been  submitted,  to use  commercially  reasonable  efforts  to  ensure  that it
receives  a  Product  Approval  for such  Product  from the FDA on the  earliest
possible  schedule  given the FDA process.  It is understood and agreed that the
Product  Approval  granted  in  respect  of a  Product  will  be  registered  in
Genpharm's name or the name of one of its Affiliates.

                                       4



3.3      Status Reporting: Genpharm shall from time to time:

         (i)      advise  Resources  in  writing  of  any  unforeseen   material
                  problems  or delays  encountered  or  additional  requirements
                  imposed upon  Genpharm or its  Affiliate,  as the case may be,
                  since  the  date of its last  report  in  connection  with the
                  development  and/or  registration  of a Product  (and of which
                  Resources  has not been  otherwise  advised  pursuant  to (ii)
                  below); and

         (ii)     provide  Resources  with such  information  as  Resources  may
                  reasonably  request in writing  from time to time with respect
                  to the  status of the  development  and/or  registration  of a
                  particular Product.

3.4 Right to Terminate  Obligations Prior to Product  Approval:  Notwithstanding
Section  3.1  hereof or any other  provision  contained  in this  agreement  but
subject to the  limitations  set forth in the final  sentence  of this  Section,
Genpharm shall have the right, upon written notice to Resources,  to immediately
terminate its obligations  hereunder to develop,  and/or seek a Product Approval
for a Product or Products if, in the reasonable  opinion of Genpharm,  it is not
commercially reasonable to develop such Product or to seek to obtain or maintain
a Product Approval therefor,  including, by way of illustration only and without
limiting the generality of the foregoing, by reason of:

         (i)      technical  factors  relating to the development of the Product
                  including,   without  limitation,   the  failure  of  clinical
                  trials/bioavailability   studies   previously   conducted   by
                  Genpharm or its Affiliate,  as the case may be, in relation to
                  the Territory or elsewhere or the  introduction  by the FDA of
                  new technical  requirements,  in each case,  which  materially
                  increase the cost of developing the Product or of obtaining or
                  maintaining a Product Approval therefore;

         (ii)     withdrawal from the market of the branded counterpart of the 
                  Product in the Territory;

         (iii)    the  existence of contra  indications  relating to the Product
                  not   currently   known   which  may   adversely   affect  the
                  marketability of such Product;

         (iv)     the high cost of manufacturing the Product;

         (v)      the  shortage  of supply  of the  active  ingredient  or other
                  components essential to the manufacture of such Product;

         (vi)     the  presence  or  anticipated   presence  on  the  market  of
                  Competing Products in the Territory at the time when a Product
                  Approval for such Product is expected to be obtained or within
                  a  reasonable  time  period  thereafter  which may  affect the
                  potential selling price of the Product or Resources' potential
                  share of the market having  regard for the volume  required to
                  obtain  reasonable  economies  of scale  for  Genpharm  or the
                  Manufacturer;

                                       5



         (vii)    the  introduction  into the Territory of new branded  products
                  which   materially   adversely   affect  or  may   potentially
                  materially  adversely affect the market for the Product in the
                  Territory;

         (viii)   the  introduction   into  the  Territory  or  the  anticipated
                  introduction  into the  Territory  of a product  which has the
                  same active  ingredient  and is for the same  indication  as a
                  Product  but  which is in a  different  dosage  form and which
                  materially  adversely  affects  or  may  materially  adversely
                  affect the market for such Product in the Territory; or

         (ix)     the institution of any suit,  action or other legal proceeding
                  against  Genpharm  or its  Affiliates,  as the case may be, or
                  against any other Person  alleging that the development of the
                  Product  as  contemplated  by  Genpharm  or the  Affiliate  in
                  question  breaches the proprietary  rights of any Person which
                  proceeding, in the reasonable opinion of Genpharm, could delay
                  the ability of Genpharm or such  Affiliate to obtain a Product
                  Approval  for the  Product to a point in time where  marketing
                  the Product will no longer be economically feasible and/or the
                  costs  of  litigating,  even if  successful,  will  materially
                  adversely affect the potential economic benefit which Genpharm
                  or its Affiliate may derive  through the  distribution  of the
                  Product  pursuant  to this  agreement  or could  result in the
                  liability of Genpharm or such  Affiliate for material  damages
                  or affect  their  right to develop,  manufacture  or sell such
                  Product.

Upon the exercise of such right by Genpharm this agreement,  except Sections 3.5
and 3.6 below,  shall terminate in respect of the Product in question.  Provided
that if Genpharm  exercises the rights  hereunder to terminate this agreement as
regards  more than 10 of the  Products  to which this  agreement  applies on the
Effective Date then it shall,  upon any further  exercise of such right pursuant
to this Section,  substitute  for the Product in respect of which this agreement
is to be terminated (the "Replaced  Product") a generic  pharmaceutical  product
which  in  the  opinion  of  Genpharm,  acting  reasonably,  is  a  commercially
reasonable  substitute  (the  "Substitute  Product") for such Replaced  Product.
Genpharm shall consult with Resources prior to selecting the Substitute  Product
and shall advise Resources in writing of the identity of the Substitute  Product
within  30 days of the  exercise  of its right of  termination  as  regards  the
Replaced Product pursuant to this Section,  whereupon  Schedule "B" hereto shall
be amended by the addition of the  Substitute  Product,  which addition shall be
dated and  initialled by Genpharm and  Resources for purposes of  identification
and thereafter  this agreement shall apply to the Substitute  Product.  Genpharm
acknowledges  and agrees  that once a clinical  trial/bioavailability  study has
been  successfully  completed  with  respect  to a  Product  Genpharm  shall  be
obligated to file (or cause its Affiliate to file) an ANDA with the FDA for such
Product unless  Resources  consents to Genpharm (and its  Affiliates) not filing
such an ANDA,  which consent of Resources shall not be unreasonably  withheld or
unduly delayed.

3.5      Licence of Product Information to Resources:

(a)      If Genpharm  exercises its right pursuant to Section 3.4 for any reason
         (other  than  pursuant  to  Paragraphs  3.4  (iii)  or (ix)  above)  to
         terminate this agreement in respect of a Product,  Resources shall have
         the right for a period of 20 business days  following  receipt by it of
         the notice  contemplated  in Section 3.4 hereof to require  Genpharm to
         grant (or cause the  applicable  Affiliate  to grant) to  Resources  an
         exclusive licence upon the terms herein contemplated to use the Product

                                       6


         Information  to  obtain a  Product  Approval  for such  Product  in the
         Territory  and to market and sell such  Product in the  Territory,  the
         right of  Resources  hereunder  to be exercised by notice in writing to
         Genpharm (which notice, to be effective,  shall reference this Section,
         shall  specify  the  Product to be  licenced  and shall be  received by
         Genpharm  within such 20 business day period).  The rights of Resources
         and the  obligations of Genpharm  pursuant to this Subsection (a) shall
         not  apply  to any  Products  in  respect  of  which  Genpharm  (or the
         applicable Affiliate,  as the case may be) licenses Product Information
         from a Third  Party  Licensor  if the  agreement  with such Third Party
         Licensor  prohibits Genpharm (or such Affiliate) from so licensing such
         Product  Information  to Resources  (whether  absolutely or without the
         consent of the Third Party  Licensor,  which consent  Genpharm (or such
         Affiliate)  has  been  unable  to  obtain  notwithstanding  its  use of
         reasonable commercial efforts to obtain such consent).

(b)      Following  the proper  exercise by Resources of its rights  pursuant to
         Subsection  (a) above,  Resources and Genpharm (on its own behalf or on
         behalf of its applicable Affiliate, as the case may be) shall negotiate
         in good faith the  provisions  of an  exclusive  licence  agreement  in
         relation to such Product  Information and the Product,  which agreement
         shall be executed and delivered by the licensor and Resources within 60
         days  of  the  receipt  by  Genpharm  of  the  notice  contemplated  in
         Subsection  (a) above or within 15 days of the final  determination  of
         the provisions of such licence  agreement as contemplated in Subsection
         (c) below.  Such agreement shall be prepared  initially by Genpharm and
         shall be  submitted  by  Genpharm  to  Resources  within 30 days of its
         receipt of such notice. Such agreement shall provide that:

         (i)      Resources  shall not have the right to sublicence  any Product
                  Information  or to  authorize  any other Person to use Product
                  Information  for any  purpose  (other  than to a Person who is
                  then  and  who  continues  thereafter  to be an  Affiliate  of
                  Resources and who agrees to be bound by the  provisions of the
                  licence agreement);

         (ii)     all  information,  tests  and  studies  not  contained  in the
                  Product  Information  and which are  required by  Resources to
                  obtain a Product  Approval for such Product shall be developed
                  and conducted by Resources  and/or its Affiliate at their sole
                  cost and expense;

         (iii)    the  licensor  will  answer  Resources'  reasonable  inquiries
                  concerning such Product  Information so as to enable Resources
                  to obtain a Product  Approval  for the Product in question but
                  it shall not be  required  to compile  or develop  information
                  which is not already available to or possessed by it;

         (iv)     Resources will not use the Product Information  licenced to it
                  pursuant hereto to obtain a regulatory  licence or approval to
                  market the Product  outside of the  Territory nor will it sell
                  such Product  outside of the Territory or to any Person in the
                  Territory  where Resources knows or has reason to believe such
                  Person will resell the same outside of the Territory  (and the
                  agreement will contain restrictions similar to those contained
                  in Section 2.4 hereof);

                         ASTERISKS DENOTE SUCH OMISSION

         (v)      Resources  will pay to the licensor  (and to  Genpharm,  where
                  Genpharm is not the licensor,  in the proportions  directed by
                  Genpharm)  an aggregate  royalty  equal to [****] of the Gross
                  Profits derived from Net Sales of the licensed Product made by
                  or on behalf of Resources or its  Affiliates  in the Territory
                  (determined in the manner  contemplated in this agreement with
                  the proviso  that  Resources or its  Affiliates  manufacturing
                  cost of such product calculated in the manner  contemplated in
                  the definition  "Manufacturing Cost" herein contemplated shall
                  be treated as the Transfer Price hereunder),  provided that no
                  royalty  shall be payable  on Gross  Profits  earned  from Net
                  Sales of the licensed  Product until such Gross Profits exceed
                  an amount equal to the reasonable  Development  Costs incurred
                  by Resources and its Affiliates to develop such Product and to
                  obtain the Product Approval for such Product.

(c)      Such  agreement  shall also  contain  such other  terms and  provisions
         customarily  included in license agreements for product  information as
         Genpharm and  Resources  may mutually  agree upon and in the event of a
         dispute  between such parties as to the  inclusion of any  provision in
         such  agreement or the manner of expressing  any concept,  such dispute
         shall be resolved  through  arbitration  to be conducted in  accordance
         with the provisions of Article 13 hereof.

3.6 Withdrawal from Market:  If Genpharm  terminates this agreement with respect
to a Product  pursuant to Section 3.4 hereof and Resources does not exercise its
rights pursuant to Section 3.5 in respect of such Product then neither  Genpharm
nor its Affiliate will seek a Product  Approval for such Product for a period of
18 months from the date upon which this agreement  terminates in respect of such
Product  without  offering  Resources the right to reinstate  this  agreement as
regards such Product.

3.7      Election of Resources:

(a)      At least 90 days  prior  to  Genpharm  commencing  to  manufacture  the
         validation  batches  of the  Product  required  to obtain  the  Product
         Approval for such Product,  Genpharm shall notify  Resources in writing
         of its estimated  Transfer Price of such Product (it being acknowledged
         and agreed by  Resources  that  Genpharm  shall have no  obligation  to
         manufacture  or cause its  Affiliates  to  manufacture  the  validation
         batches  until such time as Resources  has waived in writing its rights
         with  respect to such  Product  pursuant  to  Subsection  (b) below and
         submitted  to  Genpharm  [or such right has expired  and  Resources  is
         deemed to have submitted to Genpharm  pursuant to Subsection (b) below]
         a  purchase  order  for  the  Product  to be so  manufactured  in  such
         validation batches).

(b)      Notwithstanding  the  provisions  of 2.1 hereof,  within 30 days of the
         receipt by  Resources  of the notice  contemplated  in  Subsection  (a)
         above,  Resources  shall have the  right,  to be  exercised  by written
         notice  to  Genpharm,  to  immediately  terminate  its  obligations  to
         distribute  such Product  hereunder  if, in the  reasonable  opinion of
         Resources:

           CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                       SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION

         (i)      it is not commercially  reasonable to sell and distribute such
                  Product by reason of those  factors,  events or  circumstances
                  contemplated in clauses 3.4 (ii), (iii), (vii) or (viii); or

         (ii)     the Gross  Profit  which may be  earned by  Resources  and its
                  Affiliates pursuant to this agreement from the distribution of
                  such  Product  will be less than [****] of Gross Sales  having
                  regard to the  estimated  Transfer  Price of the  Product  and
                  taking into  account the presence or  anticipated  presence in
                  the market of Competing  Products at the time when the Product
                  Approval  for such  Product  is  expected  to be  obtained  by
                  Genpharm or its  Affiliate or within a reasonable  time period
                  thereafter which may affect the potential selling price of the
                  Product or Resources' potential share of the market;

         Upon the exercise of such right by Resources,  this  agreement,  except
         Subsection  (c) below,  shall  terminate  in respect of the  Product in
         question.  In the event that  Resources does not exercise such right of
         termination   within   the   time  and  in  the   manner   hereinbefore
         contemplated, Resources shall be deemed to have placed a purchase order
         with Genpharm for the products  manufactured  as part of the validation
         batches, which products shall be made available to Resources for pickup
         as  contemplated  in Section 5.3 hereof as soon as  possible  following
         receipt  by  Genpharm  or  its  Affiliates  of  the  Product   Approval
         therefore.

(c)      If Resources  exercises the right  pursuant to Subsection  (b) above to
         terminate  this agreement in respect of a Product and within 30 days of
         Genpharm or its Affiliate receiving a Product Approval for such Product
         Genpharm, despite reasonable commercial efforts in that regard, remains
         unable to engage any other Person reasonably  acceptable to Genpharm to
         exclusively distribute such Product in the Territory on its behalf upon
         terms  and  provisions  at least as  favourable  to  Genpharm  as those
         contained  herein,  Resources  shall  pay  to  Genpharm  [****]  of the
         reasonable Development Costs incurred by Genpharm and its Affiliates to
         develop the Product and to obtain a Product  Approval for such Product.
         In addition,  Resources  shall not, and shall not authorize,  permit or
         suffer any of its Affiliates to sell,  market or distribute a Competing
         Product  in the  Territory  for a period of 3 years  from the date upon
         which  Resources  shall have  elected to  terminate  this  agreement in
         respect of such Product.

3.8      Representation and Warranties re Status:

(a)      Resources  represents  and warrants to Genpharm that neither it nor any
         of its  Affiliates is prohibited by any law,  rules or regulation or by
         any  order,  directive  or  policy  from  selling  any of the  Products
         (assuming  that the  Product  Approvals  have been  obtained)  or other
         pharmaceutical products within the Territory and that neither Resources
         nor any of its  Affiliates is a Person who is listed by a United States
         federal  agency as  debarred,  suspended,  proposed  for  debarment  or
         otherwise ineligible for federal programs in the United States or other
         jurisdictions within the Territory (an "Ineligible Person").

                         ASTERISKS DENOTE SUCH OMISSION

(b)      Genpharm  represents  and warrants to Resources that neither it nor any
         of its  Affiliates  who  have  or are  developing  a  Product  for  the
         Territory  or who is or will be a  Manufacturer  thereof  is  currently
         prohibited by any law, rule or regulation or by any order, directive or
         policy  from  selling  the  Products   within  the  Territory  (on  the
         assumption  that it holds whatever  licenses are required for a foreign
         corporation to carry on business generally within such jurisdiction and
         holds Product  Approvals for such  Products) and that neither  Genpharm
         nor any such Affiliate is an Ineligible Person.

3.9 Expenses of Patent  Challenges:  Resources shall pay to Genpharm,  within 30
days of the receipt of an invoice  therefor  (which invoice shall be accompanied
with a copy of the third party  invoice  evidencing  the  expense in  question),
[****]  of the  legal  fees and  disbursements  and  other  reasonable  expenses
actually  incurred by Genpharm and its Affiliates to investigate  and defend the
claim of any Person  (hereafter  referred  to as a "Claim")  that the Product as
developed  by Genpharm  (and/or its  Affiliates)  infringes  any patent or other
proprietary right of such Person  enforceable in the Territory (such legal fees,
disbursements  and other  expenses  incurred by Genpharm and its  Affiliates  to
investigate  and defend a Claim being herein  referred to as the "Patent Defence
Expenses"). If  the  Patent  Defence  Expenses  incurred  by  Genpharm  and  its
Affiliates in respect of a Product exceeds [****] then, at any time  thereafter,
Resources  shall have the right  terminate its  obligation to fund [****] of any
future Patent  Defence  Expenses  incurred by Genpharm and its  Affiliates  with
respect to such  Product by notice in writing to  Genpharm (a  "Notice"),  which
Notice shall be effective  upon its receipt by Genpharm and shall  terminate the
obligation of Resources to fund any Patent Defence Expenses incurred by Genpharm
and its  Affiliates  with respect to such Product after the date upon which such
Notice is received by Genpharm  but,  for  greater  certainty,  Resources  shall
remain liable to Genpharm for [****] of the Patent Defence Expenses  incurred by
Genpharm and its  Affiliates to and including the date upon which such Notice is
so received by Genpharm. Termination by Resources hereunder of its obligation to
fund Patent Defence Expenses  incurred by Genpharm and its Affiliates in respect
of one or more  Products  shall not affect the  obligation  of Resources to fund
Patent Defence Expenses  incurred by Genpharm and its Affiliates with respect to
other  Products  (subject to Resources'  rights to terminate its  obligations to
fund such  expenses  with respect to any other Product or Products in accordance
with the provisions hereof).  The obligation of Resources to fund Patent Defence
Expenses  incurred in respect of a Product shall  terminate upon  termination of
this agreement in respect of such Product  provided that Resources  shall remain
liable to Genpharm  for the Patent  Defence  Expenses  relating to such  Product
incurred prior to such date of termination (to the extent it is otherwise liable
therefor), which liability shall survive the termination of this agreement. Upon
a written  request of  Resources  Genpharm  will  authorize  the lawyer or other
representative of Genpharm or its applicable Affiliate engaged in the defense or
investigation  of such Claim to discuss with and disclose to Resources  possible
future Patent Defense Expenses to be incurred in the investigation or defense of
the Claim.

3.10 Right of First Refusal - Development:  Resources acknowledges and agrees on
its own behalf and on behalf of its  Affiliates  that they shall not commence to
develop any generic  pharmaceutical  product for the  Territory not under active

                                       10


development  by Resources or any of its Affiliates on the Effective Date without
first offering to Genpharm,  by notice in writing (which notice shall specify in
respect of such product,  its dosage form,  indications and strengths) the right
to develop such product  (either itself or through one of its  Affiliates) as an
additional product to which this agreement shall apply.  Genpharm shall,  within
45 days of the receipt of such notice, notify Resources whether or not it wishes
to add such product to this  agreement  (and,  in the absence of any such reply,
Genpharm shall be deemed to have declined such offer).  If Genpharm  declines or
is  deemed to have  declined  such  offer  Resources  and  Genpharm  (and  their
respective  Affiliates)  shall  each be free to  develop  such  product  for the
Territory free of any rights of the other. Subject to the final sentence of this
Section, if Genpharm accepts such offer within the time and in the manner herein
provided  such product  shall be added to Schedule "B" hereto as a product to be
developed for the Territory by Genpharm  and/or its  Affiliate  (which  addition
shall be dated and initialled by the parties for purposes of identification) and
thereafter the terms of this agreement shall govern such product.  Provided that
from and after the date, if ever,  upon which Merck KGaA and its Affiliates hold
collectively  less  than  33-1/3%  of  the  issued  and  outstanding  shares  of
Resources' common stock,  Resources shall have no further obligation pursuant to
this  section to offer to  Genpharm  the first right to develop  products  which
Resources and its Affiliates proposes to develop as herein  contemplated.  Where
Resources' proposes to develop such product and obtain an ANDA approval therefor
from the FDA based upon a licence of Product Information from a third party then
any  exercise  by Genpharm  of its right  pursuant to this  Section to have such
product added to this  agreement  shall be null and void (and such product shall
not be added to this  agreement  with each such party being free to develop such
product independently as hereinbefore contemplated) if Resources, within 60 days
of the  exercise  by Genpharm of such right  hereunder,  can provide  reasonable
evidence that Genpharm and its Affiliates do not have the ability to develop and
have such product available to market within a reasonably comparative time frame
to that within which  Resources could  reasonably  develop and have such product
available to market based upon the third party's licenced information.

efforts to manufacture (or cause to be manufactured) and supply to Resources, in
accordance  with the  terms and  conditions  set  forth  herein  and in a timely
fashion,  reasonable  quantities  of such  Product.  Resources  shall order from

                                       11


4.4 Quality Control and Assurances and Release Documentation: Genpharm shall or,
shall cause the  Manufacturer  to, perform all in-process  quality control tests
and  quality  assurance  reviews  on the  Product  as  required  by the  Product
Manufacturing  Requirements  and  shall,  or shall  cause the  Manufacturer  to,
certify in writing that each batch of the Product  delivered  to  Resources  was
manufactured in strict  conformity with the Product  Manufacturing  Requirements
and the other terms of this agreement.

4.5 Product  Warranty:  Genpharm  warrants  that all  Product  supplied by it to
Resources  pursuant to this agreement shall be manufactured,  packaged,  tested,
stored and handled in accordance with the Product Manufacturing Requirements and
that at the time of the delivery of such Product to the carrier at Genpharm's or
the  Manufacturer's  Plant,  as the case may be, such  Product:  (i) will not be
adulterated  or  misbranded  within the  meaning of the Federal  Food,  Drug and
Cosmetic Act ("Act"),  as amended, or within the meaning of any applicable state
or municipal law in which the  definitions of  adulteration  and misbranding are
substantially  the same as those contained in the Act, as such Act and such laws
are  constituted  and  effective at the time of delivery and (ii) will not be an
article which may not, under the provisions of Sections 404 and 505 of such Act,
be introduced into interstate  commerce.  NEITHER  GENPHARM NOR THE MANUFACTURER
MAKES ANY REPRESENTATION  THAT THE PRODUCT IS USEFUL FOR THE INTENDED PURPOSE OR
THAT IT IS FREE FROM INHERENT SIDE EFFECTS EXCEPT AS EXPRESSLY SET FORTH IN THIS
AGREEMENT.


                                    ARTICLE 5
                   PRODUCTION FORECASTS, ORDERS AND DELIVERIES

5.1 Forecasts and Commitments:  To assist Genpharm to schedule production of the
Products,  Resources  shall  provide to  Genpharm  (or as it  directs)  for each
Product to be manufactured  and supplied to Resources  hereunder,  quarterly (at
least  45 days in  advance  of the  commencement  of the  first  calendar  month
forecasted  thereunder),  a 12 month rolling  forecast of  Resources'  estimated
requirements  of the Product,  which  forecast  shall  represent a commitment of
Resources  to purchase  the  quantity of Product  projected  for the first month
thereunder and a commitment, subject to a 20% variance, to purchase the quantity
of Product  forecasted  for the second and third months  forecasted  thereunder.
Subject to the foregoing,  all forecasts are estimates only and Resources  shall
only be bound to purchase the Product pursuant to purchase orders submitted,  or
deemed  hereunder  to be  submitted,  by it to  Genpharm  (or to such  person as
Genpharm  may  direct).  All  purchase  orders for a Product  shall  specify the
delivery  date  therefor,  which  delivery date shall be no sooner than 16 weeks
following  the receipt of such order by Genpharm or such other period of time as
Genpharm  shall  specify in writing to Resources  within a reasonable  period of
time following  receipt by Genpharm or the  Manufacturer of the Product Approval
for such  Product.  Resources  shall  deliver the first such  forecast  within a
reasonable period of time following receipt of such Product Approval by Genpharm
or the Manufacturer and shall deliver the updated and extended forecasts every 3
months thereafter.

5.2 Purchase  Orders:  All orders for Product  shall be placed using  Resources'
standard form of purchase order and shall be invoiced using Genpharm's  standard


                                       12


form of invoice.  All purchase orders  submitted by Resources shall  contemplate
the purchase of Product in minimum batch sizes as contemplated in the applicable
Product  Approval or multiples  thereof  (unless  Genpharm  agrees in writing to
smaller  quantities  [either generally or in respect of any particular  purchase
order]) and shall specify,  amongst other things, the required delivery date. In
the event of any conflict  between the terms of any purchase order and the terms
of any invoice related thereto, the terms of the purchase order shall govern. In
the event of any conflict  between the terms of any purchase order and the terms
of this agreement,  the terms of this agreement shall govern (unless the parties
shall have mutually agreed to the contrary in writing in respect of a particular
instance).

5.3      Delivery of Product:

(a)      Products  shall be made  available  to  Resources  for  pickup  in bulk
         containers  (where  applicable)  at  Genpharm's  or the  Manufacturer's
         Plant, as the case may be.  Resources shall arrange for shipping and/or
         transportation  of the Products  from such Plant to  Resources'  Spring
         Valley,  New York  facility  and pay all  shipping  and related  costs,
         including insurance,  and any customs duties and other taxes imposed on
         the  importation of the Product into the Territory.  Genpharm shall (or
         shall cause the  Manufacturer to) promptly notify Resources by fax that
         any order (or part  thereof) is available for pick-up at its or at such
         Manufacturer's Plant (this notice shall hereafter be referred to as the
         "Availability  Notice").  Resources  shall  use  reasonable  commercial
         efforts to pick up the Products that are the subject of an Availability
         Notice within 10 business days of receipt of the  Availability  Notice;
         provided  that,  if such  pickup  has not  occurred  on or prior to the
         expiry of such 10 day  period,  Resources  shall,  for  purposes of its
         payment obligations to Genpharm pursuant to Sections 6.1 and 6.2 below,
         be deemed to have picked up the  Products  which are the subject of the
         Availability  Notice on the last business day of such 10 day period. If
         the  Products  in  question  have not been picked up by or on behalf of
         Resources within 20 business days of an Availability  Notice,  Genpharm
         may, but shall not be obligated  to, cause the Products to be delivered
         to Resources' Spring Valley, New York, facility at Resources' sole cost
         and  expense and risk of loss and title to the  Products  shall pass to
         Resources   upon  pickup  of  the  Products  at   Genpharm's   or  such
         Manufacturer's  Plant, as the case may be, in the same manner as if the
         pickup had been  effected by Resources  itself,  provided that Genpharm
         shall  provide  for the  Products  to be  insured  during  transit in a
         commercially reasonable manner at Resources' sole cost and expense.

(b)      Genpharm shall, or shall cause the Manufacturer to, supply to Resources
         all   documentation   necessary   to  export  such   Product  from  the
         jurisdiction where its Plant is located and all documentation  required
         by Resources  to import such  Product into the  Territory to the extent
         that  same is  available  to  Genpharm  (or  such  Manufacturer)  or is
         reasonably capable of being generated by it.

(c)      Risk of loss and title to the  Products  shall pass to  Resources  upon
         pickup of the Product by, on behalf of, or for the account of Resources
         at Genpharm's or such Manufacturer's Plant as aforesaid.

(d)      Products supplied by Genpharm hereunder shall have a minimum shelf life
         of 20 months which shall run from the date that the Availability Notice
         in respect of such Product is received by Resources.

                                       13


5.4  Cancellation of Order:  Notwithstanding  anything herein  contained,  if an
Availability  Notice in respect of any Product  subject to a purchase  order has
not been given within 60 days  following the required  delivery  date  hereunder
Resources  shall be entitled to cancel such order (or portion thereof in respect
of which no  Availability  Notice  has so been  given) by notice in  writing  to
Genpharm.

5.5  Documentation to Accompany  Deliveries:  All deliveries of Product by or on
behalf of Genpharm  shall be  accompanied  by all  documentation  required under
applicable  law to import  the  Product  into,  and for  Resources  to offer the
Product for sale in, the Territory  including,  without limitation,  any quality
assurance  or quality  control  audit  results  and/or  certifications  that the
Product  Approval  for the Product  have been audited to ensure that any Product
supplied  hereunder has been manufactured in conformity with cGMP and applicable
FDA regulations.

5.6 Assistance  With Export & Import Laws:  Resources and Genpharm shall provide
such commercially reasonable assistance as the other may request relative to the
exportation or importation of Products not expressly provided in this agreement.

                           PAYMENTS, REPORTS AND AUDIT


6.1      Purchase Price:

(a)      The purchase  price payable by Resources for Product  supplied to it by
         or on behalf of Genpharm  shall be the  aggregate  of (i) the  Transfer
         Price of such Product and (ii) the additional  consideration to be paid
         to  Genpharm  pursuant to Section 6.3 hereof in respect of Net Sales of
         such Product.

(b)      In addition to such purchase price  Resources  shall pay all applicable
         sales tax, use tax,  consumption  tax,  goods and services  tax,  value
         added tax or similar tax, imposts or duties levied upon the sale of the
         Product by Genpharm to Resources  whether  that tax,  impost or duty is
         levied  under the laws of the  jurisdiction  where  the  Manufacturer's
         Plant is located or the  jurisdiction  where  Resources  or Genpharm is
         located  (or of any  state,  province,  territory  or  other  political
         subdivision thereof) and whether it is currently in force or comes into
         force after the Effective Date of this agreement.

(c)      The Transfer Price shall be invoiced and all payments  hereunder  shall
         be made in U.S. dollars.  Any costs or expenses which are to be paid by
         Resources   hereunder  or  which  were   incurred  by  Genpharm  (or  a
         Manufacturer, as the case may be) in a currency other than U.S. dollars
         shall be converted into its U.S.  dollar  equivalent in accordance with
         the usual  procedures  therefore  used by  Genpharm  or the  applicable
         Manufacturer in determining its Manufacturing Costs.

6.2 Invoicing  and Payment:  Genpharm  shall invoice  Resources for the Transfer
Price of the  Product  at the time such  product is picked up or is deemed to be
picked up by or on behalf of Resources as  contemplated in Section 5.3 hereof or

                                       14


within a reasonable  period of time thereafter.  The Transfer Price shall be due
and payable within 45 days following the date of such invoice.  Each shipment of
Product to Resources shall constitute a separate sale,  obligating  Resources to
pay the  purchase  price  therefor,  whether  such  shipment be in whole or only
partial fulfilment of any order.

6.3      Additional Consideration:

(a)      As additional  consideration  for the Products  Resources  shall pay to
         Genpharm the Applicable  Percentage of the Gross Profits arising out of
         Net Sales in the  Territory by Resources or its  Affiliates  of Product
         supplied by or on behalf of Genpharm pursuant hereto,  which additional
         consideration  shall be paid to Genpharm as part of the purchase  price
         for the  Product  sold and shall not be treated as a royalty or similar
         payment.

 (b)     The payment to Genpharm of its share of Gross  Profits shall be made in
         U.S  dollars.  For the  purposes  of  determining  Gross  Profits,  any
         delivery  costs or other  expenses  incurred  by  Resources  which  are
         relevant to the  calculation  of Gross Profits and which are payable or
         were paid in a currency other than U.S. Dollars shall be converted into
         their U.S. dollar  equivalent  based upon the rate of exchange  between
         the  currency  in  question  and U.S.  dollars as  reported in the Wall
         Street  Journal on the 2nd business day  preceding the day on which any
         such payment on account of Gross Profits is due.

6.4  Payment  of  Additional   Consideration  and  Accompanying   Documentation:
Genpharm's  share  of  Gross  Profits  shall be paid by  Resources  to  Genpharm
quarterly,  within 30 days following the end of each calendar quarter (being the
last day of March,  June,  August and December in each year) with respect to Net
Sales made by Resources or its Affiliates of such Products  during such calendar
quarter.  Each such payment shall be  accompanied by the following in respect of
each Product supplied by or on behalf of Genpharm:

(a)      a sales summary  reasonably  satisfactory to Genpharm showing all sales
         of such Product by Units  (sku's) and dollars made by Resources and its
         Affiliates during the quarter in question;

(b)      a detailed statement showing all returns, adjustments, credits, rebates
         and other debits and credits  relevant to the  calculation of Net Sales
         of such Product for the quarter in question together with copies of all
         documentation  to support  allowable  deductions  used in computing Net
         Sales during such quarter;

(c)      a detailed statement showing Repackaging Expenses,  Recall Expenses and
         Excess Reprocurement Costs incurred by Resources and its Affiliates and
         duties and taxes  recovered by Resources and its  Affiliates  which are
         relevant  to the  calculation  of  Gross  Profits  for the  quarter  in
         question;

(d)      a  certificate  signed  by the Chief  Financial  Officer  of  Resources
         certifying that, to the best of his knowledge,  information and belief,
         after reasonable  investigation,  the foregoing statements contemplated
         in (a),  (b) and (c)  above  are true and  correct  and do not omit any
         material  information required to be provided pursuant to this Section;
         and

(e)      a summary of the  calculation of the Gross Profits  payable to Genpharm
         on such date.

                                       15


For purposes of this  agreement a sale shall be  considered to have been made at
the  time the  Product  is  shipped  by  Resources'  or its  Affiliate's  to its
customer.  For purposes of computing Net Sales, all sales and other transactions
between Resources and its Affiliates shall be disregarded.

6.5 Additional Information:  Resources shall provide to Genpharm and shall cause
its Affiliates to provide to Genpharm,  promptly  following a request  therefor,
such  additional   information  concerning  any  sales  of  a  specific  Product
(including,  without  limitation,  in  respect  of any  sale,  the  date  of the
shipment,  the name of the customer, the number of Units of the Product (by sku,
if  requested)  sold to such customer and the invoice price charged by Resources
or its Affiliates), chargebacks, credits, returns, adjustments and other credits
and debits relevant to the calculation of Net Sales and Gross Profits in respect
of a Product  including  information  relating to Repackaging  Expenses,  Recall
Expenses and Excess  Reprocurement Costs incurred in or applicable to any period
in respect of such Product, as Genpharm may reasonably request.  Genpharm shall,
or shall cause the applicable  Manufacturer  to, provide to Resources,  promptly
following  a  request  therefor,  such  additional  information  concerning  the
calculation of the Transfer Price of Products  previously  supplied to Resources
hereunder as Resources may reasonably request.

6.6 Interest:  All payments to be made to Genpharm  under this  agreement  shall
bear interest from and after the  Applicable Day (as that term is defined below)
until  paid at the  annualized  rate  equal  to the  daily  (as at the  close of
business  on each such day) prime rate as quoted  from time to time by  Citibank
N.A., New York, New York plus 5%, compounded daily. For purposes of this Section
the term "Applicable Day" shall mean:

         (i)      where the  payment is on account  of the  Transfer  Price of a
                  Product  which has not been made on its due date and Resources
                  has not on 2 or more  occasions  during the same calendar year
                  failed to pay a Transfer Price to Genpharm on its due date, 30
                  days after the due date therefore;

         (ii)     in any other case, the due date therefore.

6.7 Maintenance of Records:  Each of Genpharm and Resources agrees that it shall
keep (and shall cause its  Affiliates to keep)  complete and accurate  books and
records of account  containing all information  required for the computation and
verification  of all amounts on which  payments  hereunder  are based and shall,
upon reasonable  written notice from the other,  make such records available for
examination by such other party or, at the requesting  party's  expense,  supply
copies of such records to such other party.

6.8 Examination of Records: Each of Genpharm and Resources shall have the right,
upon  reasonable  written  notice to the  other,  to  designate  an  independent
certified  public or  chartered  accountant  (except one to whom the other has a
reasonable  objection)  to have access  during  ordinary  working  hours to such
records as may be necessary to audit the  correctness of any invoice,  report or
payment made under this  agreement.  Genpharm and  Resources  shall  provide and
shall cause its  Affiliates  to provide to the  accountant  engaged by the other
full and complete access to their pertinent books and records. In the event that
any accountant  shall have questions  which are not in his judgment  answered by
such books and  records,  the  accountant  shall  have the right to confer  with
representatives of the Person whose books and records are under review including
its Chief Financial Officer.  If any audit under this Section 6.8 shall reveal a

                                       16


discrepancy  by more than 3% of any amount  payable  hereunder or $10,000.00 US,
whichever   is   greater,    the   costs   and   expenses   relating   to   such
investigation/audit  shall be  borne by the  party  creating  such  discrepancy.
Genpharm and Resources shall each have the right to audit such books and records
of the other  pursuant  to this  Section  6.8 no more  often  than  twice in any
contract  year (as  hereinafter  defined)  unless in any of the prior 3 contract
years such  investigation  revealed a discrepancy  by more than 3% or $10,000.00
US, as aforesaid,  in which case  Genpharm or Resources  shall have the right to
audit such books and records of the other 3 times in such contract year. For the
purposes  hereof,  a contract year shall be a period of 12 months  commencing on
the Effective Date of this agreement or on an  anniversary  thereof.  Any Person
whose books and records are to be audited in accordance  with the foregoing may,
as a condition  to  providing  any  accountant  access to its books and records,
require such accountant to execute a reasonable confidentiality agreement.

6.9 Survival of  Obligation:  The obligation to make the payments and to provide
the  reports  contemplated  in this  Article 6 and the rights of  Resources  and
Genpharm  to conduct  audits or  investigations  pursuant  to Section 6.8 hereof
shall survive the  termination or expiration of this agreement or thereafter and
shall apply to all  Products  supplied to  Resources by or on behalf of Genpharm
pursuant  hereto prior to the effective date of the termination or expiration of
this  agreement or  thereafter  notwithstanding  that such Product may have been
resold by Resources or its Affiliates to its customers  after the termination or
expiration of this agreement. For greater certainty, the parties acknowledge and
agree that  Resources  shall pay to Genpharm the  Applicable  Percentage  of the
Gross Profit  derived from Net Sale of all Products  supplied by or on behalf of
Genpharm to Resources  pursuant to this agreement  irrespective  of whether such
Product is resold by Resources or its  Affiliate  prior to or  subsequent to the
termination or expiration of this agreement.

                          REPACKAGING AND DISTRIBUTION


7.1      Resources' Repackaging Responsibilities:

(a)      Resources  shall  repackage  and  relabel  the  Product  into  finished
         labelled  Units for sale in the  Territory in an FDA approved  facility
         and shall be solely  responsible  for the  contents  of the  labels and
         artwork on all Units of finished  labelled  Product  sold or  otherwise
         released by Resources (except for information  contained in such labels
         which are also contained on the labels of the bulk Product  supplied by
         or on behalf of Genpharm to Resources pursuant hereto).  In repackaging
         and  relabelling  the  Product  Resources  shall  comply  with  (i) the
         Specifications for such Product, (ii) applicable FDA cGMP and (iii) all
         other applicable rules, regulations and requirements of the FDA and any
         other  applicable  governmental  or  regulatory  bodies,  agencies  and
         officials in the Territory relative to repackaging and labelling of the
         Product for sale in the Territory.  All labels and all artwork concepts
         on  all  packaging  material  used  by  Resources  in  connection  with
         relabelling  and  packaging of a Product  shall be subject to the prior
         reasonable approval of Genpharm, provided that the approval by Genpharm

                                       17


         of any label or artwork  concept shall not relieve or otherwise  affect
         Resources'  obligations  or  responsibilities  hereunder in relation to
         relabelling  and  packaging of the Product or arising out of the use of
         such  labels or  packaging  material  or the  release of Product in the
         Territory  so  labelled  and  packaged  (or  impose any  obligation  or
         responsibility  on Genpharm in connection with such labels or packaging
         material or their use or release,  as  aforesaid,  except as  expressly
         contemplated   above  with  respect  to  the  contents  of  information
         contained  on  the  labels  which  was  provided  by  or on  behalf  of
         Genpharm).

(b)      Genpharm shall, or shall cause the Manufacturer to, supply to Resources
         all information and data relating to a Product which it is obligated to
         provide to Resources and its  Affiliates as a repackager and relabeller
         of such Product pursuant to applicable  laws.  Genpharm shall, or shall
         cause the  Manufacturer  to,  deliver  to  Resources,  upon  reasonable
         request of Resources,  a copy of all  correspondence  which it receives
         from or forwards to the FDA or other regulatory  authority with respect
         to a  Product  following  receipt  of  its  Product  Approval  therefor
         provided  that  such  correspondence  does  not  contain   Confidential
         Information  of  Genpharm  or such  Manufacturer  which it  desires  to
         maintain  confidential and which it is not obligated by law to disclose
         to Resources.

7.2  Resources'  Obligation re Marketing:  Resources shall use  reasonable  best
commercial efforts (utilizing its marketing, distribution and management systems
and  those of its  Affiliate)  to  develop  a  market  for the  Products  in the
Territory and to actively and  continuously  promote the sale of the Products in
the  Territory,  such efforts shall be not less than those used by Resources and
its  Affiliates  to  promote  the  sale of other  products  which  they  market.
Resources  shall be solely  responsible  for  advertising  and  promotion of the
Product and shall comply with all applicable laws, rules and regulations in that
regard including, without limitation, applicable FDA regulations and guidelines.

7.3 Pricing:  Resources  shall have sole discretion in setting the price for the
sale of the Products in the  Territory,  provided that it shall not discount the
price of any Product to enhance the sale of Resources' or any of its Affiliates'
Other  Products  (as that term is  defined  below) or use any  Product as a loss
leader or incentive to procure the sale of Resources' or any of its  Affiliates'
Other Products (including,  without limitation,  through tied or bundled sales).
Rebate and other discount  programs  (excluding  any pricing  programs where the
price of the Product is  discounted  to enhance the sale of Resources' or any of
its Affiliates' Other Products or where a Product is used as such loss leader or
incentive  or to  procure  the  sale  of  Resources'  or its  Affiliates'  Other
Products)  generally  available to  Resources' or its  Affiliates'  customers in
connection with the purchase of pharmaceutical  products shall not be prohibited
by this Section.  Any discounts to a price below what is reasonably necessary to
secure sales of any Product or  discounts  that are used to secure sale of Other
Products of Resources' or its Affiliate's  (through  bundled sales or otherwise)
will be fully  absorbed  by  Resources  out of its  share of  Gross  Profits  in
relation to the Product or will be charged to those Other  Products of Resources

                                       18


or its Affiliates that are in the product bundles,  as the case may be, and will
not directly or indirectly reduce  Genpharm's share of Gross Profits  hereunder.
For  purposes  of this  Section  7.3,  the  term  "Other  Products"  shall  mean
pharmaceutical  products  sold,  marketed  and  distributed  by Resources or its
Affiliates other than the Products.

7.4 Storage and Handling by Resources:  Resources shall ensure that all Products
made available to it by or on behalf of Genpharm  pursuant to this agreement are
transported,  received,  handled,  stored and delivered in  accordance  with the
Specifications  for the Product applicable thereto and applicable cGMP and other
FDA requirements  (and the requirements of all other applicable  governmental or
regulatory  bodies,  agencies  or  affiliates  in the  Territory)  so that  such
Products  do  not  become   adulterated   or  otherwise   cease  to  meet  their
Specifications  as  a  result  of  any  acts  or  omissions  of  Resources,  its
Affiliates,  and their respective agents,  employees,  transporters or those for
whom Resources or its Affiliates are responsible.

7.5  Release of Product By  Resources:  Resources  shall  conduct or cause to be
conducted such quality control tests as it deems necessary or as are required by
law  (including  any  rules,  regulations  and  requirements  of the FDA and the
requirements of all other applicable  governmental or regulatory body, agency or
officials in the  Territory)  prior to sale or other release of a Product in the
Territory.

7.6 Credit  Risks:  Resources  shall assume sole  responsibility  for all credit
risks and  collections  of  receivables in respect of Products sold by it or its
Affiliates in the Territory and in respect of all dealings between  Resources or
its  Affiliates  and its  customers  and any third  parties from whom  Resources
and/or  its  Affiliates  sources  any  goods  and  services  required  by  it in
connection  with  repackaging,   labelling,  transporting,  storing,  promoting,
marketing, selling or delivering the Product.

7.7  Repackaging  and  Marketing  Expenses:  For  greater  certainty,  Resources
acknowledges  and agrees that it shall be solely  responsible  for all costs and
expenses  incurred  by it or its  Affiliates  in  connection  with  relabelling,
packaging,  promoting,  marketing  and selling the Products in the Territory (or
otherwise  performing its  obligations  hereunder)  without any right to recover
same directly or indirectly from Genpharm (save and except for partial  recovery
of permitted  listing fees and other similar payments  contemplated in Paragraph
(iv)  of the  definition  "Net  Sales"  and  Repackaging  Expenses  through  the
calculation and sharing of Gross Profits hereunder).


                                    ARTICLE 8
                         PRODUCT REJECTIONS AND RETURNS

8.1      Product Rejection:

(a)      Within 35 days from the date of  receipt  of each  delivery  of Product
         Resources  shall inspect the Product  (Resources  hereby  acknowledging

                                       19


         that its failure to inspect  shall not release it from the  obligations
         it would  otherwise  have had it  conducted  an  inspection  as  herein
         contemplated,  or provide it with additional  rights).  Resources shall
         advise  Genpharm  in writing (a  "Rejection  Notice")  if a shipment of
         Product is not in conformity with Genpharm's  obligations  hereunder or
         is otherwise defective,  provided,  however, that Resources' failure to
         advise  Genpharm in a timely manner that a shipment of Product does not
         conform  shall not prejudice  Resources'  right to reject or return the
         Product if the defect or other non-conforming condition which justifies
         rejection  or  return  could  not  have  been  detected  by  Resources'
         inspection in accordance with cGMP standards.  If Resources  delivers a
         Rejection  Notice  in  respect  of all or any  part  of a  shipment  of
         Product,  then Genpharm and Resources  shall have 60 days from the date
         of Genpharm's  receipt of such notice to resolve any dispute  regarding
         whether all or any part of such  shipment  of Product  fails to conform
         with the Product  Specifications  or is otherwise  defective.  Disputes
         between  such  parties  as to  whether  all or any  part of a  shipment
         rejected by Resources conforms with Product Specifications not resolved
         in the 60 day  period  shall  be  resolved  by an  independent  testing
         laboratory or a consultant ( if not a laboratory  analysis issue),  the
         cost of  which  shall be paid by the  party  least  successful  in such
         dispute.

(b)      In the event any Product is appropriately  rejected by Resources (being
         Product  which does not satisfy the Product  warranty  contemplated  in
         Section  4.5 as a result of any act by or  omission  of Genpharm or the
         Manufacturer),  Genpharm  shall replace such  Products with  conforming
         goods within 16 weeks or, if requested by  Resources,  provide a credit
         to Resources  for the Transfer  Price  previously  paid by Resources to
         Genpharm  on  account  of  the  Product  in   question,   and  for  all
         transportation  and  insurance  costs,  duties,  taxes and fees paid or
         payable by Resources to import and deliver the Product in question from
         Genpharm's  or  the  Manufacturer's  Plant,  as the  case  may  be,  to
         Resources'  facility in Spring  Valley,  New York.  The credit shall be
         provided  immediately  following  the expiry of the period during which
         Genpharm may dispute a Rejection  Notice as  contemplated in Subsection
         (a) above  (unless the  Rejection  Notice is disputed by  Genpharm,  in
         which  event such  credit  shall only be given upon  resolution  of the
         dispute).  Replacement  Products  shall be delivered to Resources at no
         cost to  Resources  if  Resources  has  already  paid for the  rejected
         Products and not received a credit therefor, as aforesaid.

(c)      For  purposes  of Section  10.2  hereof,  once a Product is rejected by
         Resources,  Resources'  obligation  to pay for  such  Product  shall be
         suspended until such time as it is determined:

         (i)      by the independent laboratory or consultant that the Product
                  should not have been rejected by Resources; or

         (ii)     by the parties or by any arbitration conducted pursuant hereto
                  or by a final  order  of a  court  of  competent  jurisdiction
                  (which is not  subject  to further  appeal)  that no act by or
                  omission of Genpharm or the  Manufacturer was the cause of the
                  problem.

                                       20


8.2      Products Returns:

(a)      Notwithstanding  the  provisions of Section 8.1 hereof,  Genpharm shall
         accept the return of any Product  which is returned to Resources by its
         customers because of defects  (including  failure to meet the Product's
         Specifications)  which are due to any act or omission of  Genpharm.  In
         the event of such an accepted  return,  Genpharm shall provide a credit
         to Resources  for the Transfer  Price paid by Resources to Genpharm for
         the returned  Product and all  transportation  and insurance  costs and
         custom duties,  taxes and fees paid by Resources  upon the  importation
         and  delivery of such  Product from  Genpharm's  or the  Manufacturer's
         Plant, as the case may be, to Resources' facility in Spring Valley, New
         York (or an allowance on account  thereof) or, at  Resources'  request,
         shall make available to Resources,  without charge, replacement Product
         within a period of 16 weeks. At Resources' option, and with the consent
         of Genpharm,  which shall not be unreasonably  withheld,  Resources may
         destroy any Product returned to it.

(b)      Any return of Product  accepted by Resources  from its customers in the
         ordinary  course of business,  including  without  limitation,  Product
         returned  as  defective  due  to  acts  or  omissions  attributable  to
         Resources,  its  Affiliates  or their  respective  agents or employees,
         shall be treated as returns for the purpose of calculating Net Sales so
         that when Resources next  calculates the share of Gross Profits payable
         to Genpharm in respect of the Product in question, it shall not include
         (if the sale of the returned  Product was not previously  included in a
         prior  reporting  period)  or  it  shall  deduct  from  Net  Sales  (if
         previously  included in respect of a prior  reporting  period),  as the
         case may be,  an  amount  equal to the  Gross  Profit  attributable  to
         returned Product, it being the intention of Genpharm and Resources that
         no share of  Gross  Profit  shall be paid or  payable  to  Genpharm  in
         respect of the sale of a returned Product.

(c)      In the event any  Product is  returned  to  Genpharm  by its  customers
         because the Product is alleged to be defective and  Resources  believes
         that  such  defect  is due to an act or  omission  of  Genpharm  or the
         Manufacturer,  Resources  shall  notify  Genpharm  within a  reasonable
         period  of any such  return  and shall  provide  or make  available  to
         Genpharm (or, at Genpharm's  direction,  the Manufacturer) such samples
         (if available) and other  information  concerning the returned  Product
         available  to Resources  or its  Affiliate so as to allow  Genpharm (or
         such  Manufacturer)  to  test  and  evaluate  the  allegedly  defective
         Product.  Resources shall retain a sufficient  number of samples of the
         allegedly defective Product so that additional samples are available at
         a later date should  additional  testing be required by an  independent
         testing  laboratory  or consultant as  contemplated  in Subsection  (d)
         below, or by Resources or by Genpharm (or such  Manufacturer) for their
         own  purposes.  If not  enough  samples  exist to be so  divided,  then
         Resources  and  Genpharm  shall  confer and reach  agreement  as to the
         handling of any available samples.

                                       21


(d)      Genpharm  shall  complete  its review and  evaluation  of the  returned
         Products  (or  cause the  Manufacturer  to  complete  such  review  and
         evaluation)  within 20 business days of receiving the returned Products
         from  Resources or such longer  period of time as may be  reasonable in
         the circumstances to enable Genpharm (or such  Manufacturer) to conduct
         or cause to be conducted such tests,  studies or investigations (and to
         receive the results therefrom) as may be required to confirm or dispute
         the  existence  of the  problem  or to  identify  the  cause or  source
         thereof.  If Genpharm asserts that the returned  Product  satisfies the
         Product Manufacturing Requirements or that the defect is not due to any
         act or omission of Genpharm or the Manufacturer, representative samples
         of the Product shall be submitted to a mutually acceptable  independent
         testing  laboratory or consultant (if not a laboratory  analysis issue)
         for  analysis or review,  the costs of which shall be paid by the party
         against whom the  discrepancy  is resolved.  If it is determined by the
         independent laboratory or consultant that the returned Product does not
         satisfy the Product warranty  contemplated in Section 4.5 and that such
         failure  is  due  to  any  act  by  or  omission  of  Genpharm  or  the
         Manufacturer,  then the replacement  Product in respect of the returned
         Product shall be delivered to Resources  without  charge or appropriate
         credit  (or  allowance)  shall be given  therefor  as  contemplated  in
         Subsection 8.2(a) hereof.

8.3 Exclusive  Remedy:  Subject to Section 9.1 and 9.2 hereof and to its rights,
if any, to recover  expenses  associated  with a Recall as herein  contemplated,
Resources hereby  acknowledges and agrees (on its own behalf or on behalf of its
Affiliates)  that the sole remedy for  Genpharm's  failure to supply  Product in
accordance with the provisions of this agreement  (unless such failure is wilful
or due to gross negligence of Genpharm or the Manufacturer, if applicable) shall
be to require  Genpharm to replace the Product that does not meet such Product's
warranty  hereunder with conforming  goods within the time periods  hereinbefore
contemplated or to provide Resources with a credit in the amount contemplated in
this  Article  and that  Genpharm  (and its  Affiliates)  shall not be liable to
Resources for consequential or incidental damages including, without limitation,
loss of profits or prospective  profits of any kind (and that neither  Resources
nor any of its Affiliates shall have any rights or recourse  whatsoever  against
the Manufacturer,  all of which rights and recourses,  if any, are herein waived
and released);  provided that in the event that Genpharm fails to supply Product
(or  replacement  Product)  to  Resources  in  accordance  with its  obligations
hereunder  and,  as a result of such  failure,  a customer of  Resources  or its
Affiliate is entitled to cancel an order for such Product from  Resources or its
Affiliate  and to source a Competing  Product from an alternate  source (being a
Person other than Resources or any of its Affiliates)  and to require  Resources
or its Affiliate to pay to such  customer the  reasonable  excess  reprocurement
costs incurred by such customer, then Genpharm's responsibility shall be limited
to  reimbursing   Resources  for  the  Applicable   Percentage  of  such  excess
reprocurement  costs  actually paid or credited by Resources or its Affiliate to
its customer  (such costs being the  difference  between the landed cost to such
customer of such Competing  Product over and above the sale price of the Product
in question from Resources to such customer [the "Excess Reprocurement Costs"]).

                                       22


8.4 Return Policy: Other than Product which have been appropriately  rejected by
Resources  pursuant to Section 8.1 above or returned  Product as contemplated in
Subsection 8.2(a) above Resources shall not have the right to return to Genpharm
any Product purchased by it without Genpharm's prior written consent.

8.5 Survival of  Provisions:  The provisions of this Article 8 shall survive the
termination or expiration of this agreement.

                                    ARTICLE 9
                     DAMAGES, INDEMNIFICATION AND INSURANCE


9.1 Limitation re Claims:  Subject to the  limitations set forth in this Section
9.1,  Resources and Genpharm covenant and agree to indemnify,  save harmless and
compensate  the other (and its  Affiliates,  for whose  benefit such other party
shall hold the benefit of this provision in trust) from,  against or for, as the
case may be, any and all  claims,  demands,  actions,  causes of action,  suits,
proceedings, judgements, damages, expenses (including reasonable attorney's fees
and expenses),  losses, fines,  penalties and other similar assessments,  as the
case may be, (the "Damages")  relating to or arising out of a breach by Genpharm
or  Resources,  as the case may be, of any of the  representations,  warranties,
covenants or agreements  herein;  provided that,  except where the breach arises
out of the representation or warranty being intentionally false or inaccurate or
constitutes a wilful  material  breach by Genpharm or Resources of its duties or
obligations hereunder or an act or omission  constituting gross negligence,  the
claim of the  aggrieved  party for Damages  arising  out of the breach  shall be
limited to claiming the amounts  owing or payable to it in  accordance  with the
provisions of this agreement and any out of pocket costs and expenses (including
amounts paid or payable by it to third parties,  other than Excess Reprocurement
Costs [except to the extent  contemplated  in Section 8.3 hereof])  which it has
incurred  and the  aggrieved  party shall not be  entitled  to recover  from the
defaulting  or  breaching  party any lost profits or  consequential  or punitive
damages, including loss or damage to its goodwill or reputation.

9.2 Third  Party  Claims:  In the event  that the sale or other  release  in the
Territory by Resources or its Affiliates of any Product supplied by or on behalf
of Genpharm to  Resources  pursuant to this  agreement  results in a third party
claim:

(a)      to the extent that the Damages  awarded or incurred  relate to or arise
         out  of the  manufacturing,  testing,  bulk  packaging,  labelling  (if
         applicable),  storage  or  handling  of  a  Product  by  Genpharm  or a
         Manufacturer   or  any  other  act  by  or  omission  of  Genpharm,   a
         Manufacturer  or any other Persons for whose acts or omissions they are
         responsible  at law Genpharm  shall be  responsible  therefor and shall
         defend,  indemnify and hold harmless  Resources and its Affiliate  from
         and against all such Damages; and

                                       23


(b)      to the extent that the Damages  awarded or incurred  relate to or arise
         out  of  transporting,   receiving,   manufacturing   (if  applicable),
         repackaging,  labelling (if applicable),  testing,  storage,  handling,
         use,  marketing,  distribution,  sale  or  delivery  of  a  Product  by
         Resources  or  its  Affiliates  or any  other  act  by or  omission  of
         Resources,  any of its  Affiliate or any other Person for whose acts or
         omissions  they or any one or  more  of  them  is  responsible  at law,
         Resources shall be responsible therefor and shall defend, indemnify and
         hold  harmless  Genpharm and its  Affiliates  from and against all such
         Damages;

Upon the  assertion of any third party claim  against  Genpharm or Resources (or
their  respective  Affiliates)  that may give  rise to right of  indemnification
under this  agreement,  the  Person  claiming  a right to  indemnification  (the
"Indemnified  Party") shall give prompt notice to the Person alleged to have the
duty to  indemnify  (the  "Indemnifying  Party") of the  existence of such claim
(provided  that the  failure  to give such  notice in timely  fashion  shall not
release the Indemnifying Party of its obligations of  indemnification  hereunder
except to the extent that the  Indemnifying  Party has been prejudiced  thereby)
and shall give the Indemnifying Party reasonable opportunity to control,  defend
and/or  settle  such  claim  at its own  expense  and  with  counsel  of its own
selection;  provided,  however,  that the Indemnified Party shall, at all times,
have the right to fully  participate  in such  defense at its own  expense  with
separate counsel and, provided that both parties to the extent that they are not
contractually or legally excluded therefrom,  or otherwise prejudiced in a legal
position by so doing, shall co-operate with each other and with their respective
insurers in relation to the defense of such third party claim.  The Indemnifying
Party shall consult with the Indemnified Party with respect to settlement of any
claim. The  Indemnifying  Party shall have the right to settle any claim without
the consent of the Indemnified  Party,  provided that the  Indemnified  Party is
unconditionally  released from such claim and it is not otherwise  prejudiced by
the terms of settlement.  In the event the  Indemnifying  Party elects to defend
such claim,  the  Indemnified  Party may not settle such claim without the prior
written  consent of the  Indemnifying  Party. If the  Indemnifying  Party shall,
within a  reasonable  time after such  notice  has been  given,  fail to defend,
compromise or settle such claim, (or thereafter fails to diligently  defend such
claim) then the Indemnified Party shall have the right to defend,  compromise or
settle such claim without prejudice to its rights of indemnification  hereunder.
Notwithstanding  the  foregoing,  in the event of any  dispute  with  respect to
indemnity hereunder,  each party shall be entitled to participate in the defence
of such claim and to join and implead the other in any such action.

9.3  Insurance:  Each of  Resources  and  Genpharm  shall (and shall cause their
respective  Affiliates,  as required,  to) during the term of this agreement and
for a period  of not less  than 36  months  following  the  termination  of this
agreement,  carry or be subject to coverage under (as a named  insured)  product
liability insurance  (including blanket  contractual  liability) in an amount of
not less than $10 Million U.S.  combined  single limit,  which insurance will be
written  on an  occurrence  policy  form with an  insurance  carrier  reasonably
acceptable  to the other party.  Each of Genpharm and  Resources  shall,  at the
request of the other,  provide  evidence to such requesting  party of compliance
with its insurance  obligations  (and those of its Affiliate) under this Section
and evidence of renewals of any such policy, from time to time.


                                       24

                              TERM AND TERMINATION


10.1 Term:  The initial term of this  agreement  shall commence on the Effective
Date and, for each particular  Product,  shall terminate on the 10th anniversary
of the date upon which Genpharm or its Affiliate  receives the Product  Approval
for such Product, unless earlier terminated in accordance with the provisions of

notice of  termination to the other at least 180 days prior to the expiration of
the initial  term or any renewal  term,  as the case may be,  subject to earlier
termination as provided in this agreement.

10.2  Payment  and  Reporting  Defaults:  Genpharm  may, by notice in writing to
Resources,  terminate this agreement or, at its option, terminate this agreement
in respect of the  particular  Product or Products  to which the default  herein
contemplated  relates,  if Resources fails to pay to Genpharm any amount payable
by it to  Genpharm  hereunder  as and when the same  shall  have  become due and
payable or shall have failed to deliver (or caused to be delivered,  as the case
may be), in timely fashion, the reports or information  contemplated in Sections
6.4 or 6.5  hereof,  and in  either  case,  such  breach  shall  have  continued
unremedied  for a period of 15 business days after written notice of such breach
has been given by Genpharm to Resources;  provided that Resources shall not have
the right to such 15 business day grace period within which to cure such default
and Genpharm shall have the immediate  right to terminate the agreement for such
breach if Resources shall have previously breached Section 6.4 or 6.5, or failed
to  remit  any  sums of at  least  $100,000.00  to  Genpharm  when  due,  in the
aggregate,  three times in the 12 month period immediately preceding the default
in question In the event that  Resources has been given notice  pursuant to this
Section 10.2 and it disputes the alleged breach,  the dispute shall be submitted
to arbitration pursuant to Article 13 below and this agreement shall continue in
full force until such time as the arbitrator  renders his decision.  Termination
of this agreement  pursuant hereto shall be without prejudice to any other right
or remedy which Genpharm may have against Resources arising out of the breach in
question  including the right to obtain  compensation for its damages  (provided
that such right  shall be subject to the  limitations  set forth in Section  9.1
hereof).

10.3 Material Breach:  Subject to the provisions of Section 10.2 above, Genpharm
or Resources  may, by notice in writing to the other,  terminate  this agreement
or, at its option, terminate this agreement in respect only of those Products to
which the default in question  relates,  if such other party shall have breached
any of its material duties or obligations  under this agreement and such default
continues unremedied for a period of 60 days following receipt of notice of such
default (or, if such default is capable of being  remedied but is not reasonably
capable of being remedied within such 60 day period,  such longer period of time

                                       25


as is reasonable in the  circumstances,  not exceeding 90 days in the aggregate,
provided that the defaulting party has, within such 60 day period, commenced and
thereafter  actively and diligently  pursues the remedying of such default).  In
the event that a party has been given  notice  pursuant to this Section 10.3 and
such party  disputes  the alleged  breach,  the dispute  shall be  submitted  to
arbitration  pursuant to Article 13 hereof and this agreement  shall continue in
full  force  until  such  time  as the  arbitrator  renders  his  decision.  The
arbitrator shall determine whether or not there has been a breach and/or whether
or not the same has been remedied  within the required cure period.  Termination
of this agreement  pursuant hereto shall be without prejudice to any other right
or remedy the party  terminating  this agreement may have against the defaulting
party  arising  out of the  breach  in  question  including  the right to obtain
compensation  for its damages  (provided that such right shall be subject to the
limitations set forth in Section 9.1 hereof).

10.4  Events  of  Default:  Genpharm  shall  have the  right to  terminate  this
agreement  upon written notice to Resources in the event that any one or more of
the  following  events  shall  become  applicable  to  Resources  or  any of its
Affiliates to whom any material duty or obligations  of Resources  hereunder has
been  delegated or assigned and Resources may  terminate  this  agreement in the
event that any one or more of the  following  events shall become  applicable to
Genpharm  or, at its option,  may  terminate  this  agreement in respect only to
those  Products  which are being  manufactured  by a  Manufacturer  (other  than
Genpharm)  if  any  of  the  following  events  shall  become  applicable  to  a
Manufacturer (Resources, its Affiliate, Genpharm or the Manufacturer affected by
such event being referred to as the "Party"):

         (i)      an order is made or a resolution or other action of such Party

                  arrangement,  composition  or  readjustment  of its  debts  or
                  obligations  or  otherwise  proposes to take  advantage  of or
                  shelter  under any statute in force in the United States or in
                  the governing jurisdiction of such Party for the protection of
                  debtors;

         (iii)    if any proceeding is commenced with respect to a compromise or
                  arrangement,  or to have such Party  declared  bankrupt  or to
                  have a  receiver  appointed  in  respect  of such  Party  or a
                  substantial portion of its property and such proceeding is not

                  business.

10.5  Ineligible  Person:  Genpharm or Resources may terminate this agreement in
respect of a Product  upon 30 days prior  written  notice to the other  party if
such party (otherwise than by reason of a breach of its obligations hereunder in
respect of such Product) is legally  prohibited  from performing its obligations
hereunder or becomes (or, in case of Resources, its Affiliates become and in the
case of  Genpharm,  a  Manufacturer  thereof  becomes) an  Ineligible  Person in
respect of such Product  (and,  where the party  purporting  to  terminate  this
agreement is also the party prohibited from performing or it or its Affiliate as
hereinbefore  contemplated is the Ineligible  Person, it [or such Affiliate,  as
the case may be], has made  diligent best efforts to remove the  prohibition  or
its  status  as an  Ineligible  Person)  and such  prohibition  or  status as an
Ineligible Person has continued uninterrupted for a period of 120 days.

10.6 Force Majeure:  Either party may terminate this agreement with respect to a
particular  Product  materially  affected  by  an  event  of  Force  Majeure  in

and which are not effected by such Force Majeure event).

10.7 Price Erosion: Either Genpharm or Resources may terminate this agreement in
respect of a  particular  Product  (the  "Specific  Product")  on 120 days prior
written  notice to the other party if, in any calendar  year,  the Gross Profits
derived  from Net Sale of such  Specific  Product  is less than 20% of the Gross
Sales of the Specific Product during such period.

10.8     Minimum Threshold Sales: If, with respect to a Product:

         (i)      in the  first  12  month  period  (such  period  being  herein
                  referred  to as the  "Period")  commencing  on the  date  (the
                  "Commencement   Date")   which  is  the  2nd   business   days
                  immediately   following   the  date   upon   which  the  first
                  Availability  Notice (as  contemplated  in  Subsection  5.3(a)
                  hereof)  is given to  Resources  hereunder  in respect of such
                  Product,  the  aggregate  Net Sales of such  Product  for such
                  Period is less than the Threshold Amount  applicable  thereto;
                  or

         (ii)     in any  subsequent  12 month  period (a  "Subsequent  Period")
                  commencing on the  anniversary  of the  Commencement  Date the
                  aggregate number of Units of such Product sold (excluding, for
                  greater certainty, free goods) by Resources and its Affiliates
                  in such  Subsequent  Period (and  included in the Net Sales of
                  such  Product  for  such   Subsequent   Period)  is,   without
                  reasonable justification (having regard to such factors as, by
                  way of illustration  only but without  limitation,  the Market
                  Factors [as defined below]) less than 70% of the Units of such
                  Product sold (excluding, for greater certainty, free goods) by
                  Resources and its Affiliates during the Period;

and the  shortfall  in sales  cannot be  attributable  primarily to the fault of
Genpharm,  then  Genpharm  shall have the right to terminate  this  agreement in

                                       27


respect of such Product upon 90 days prior written notice to Resources.
For purposes of this Section, the term "Market Factor" means:

                  additional  Competing  Products  during  that  or a  preceding
                  Subsequent  Period which had a material  adverse effect on the
                  market  share of  Resources  and any other  manufacturers  and
                  distributors  who  were  at  the  time  of  such  introduction
                  marketing Competing Products in the Territory;

         (B)      a  significant  price  erosion  relating  to the  Product  and
                  Competing Products as a result of market forces resulting in a
                  decision  by  Resources,   acting  reasonably,   not  to  seek
                  additional and less profitable sales of such Product merely to
                  increase  Unit sales of such  Product at the  expense of Gross
                  Profit;

         (C)      the  introduction  into the Territory of new branded  products
                  which  materially  adversely  affected  the  market  for  such
                  Product  and  Competing  Products,  if any,  in the  Territory
                  during that or a preceding Subsequent Period;

         (D)      the introduction into the Territory of a product which has the
                  same active  ingredient and is for the same indication as such
                  Product  but  which is in a  different  dosage  form and which
                  materially  adversely affected the market for such Product and
                  Competing  Products,  if any,  in the  Territory  in that or a
                  preceding Subsequent Period;

         (E)      Force Majeure (as defined in Section 14.2 hereof).

10.9  Closing  Share  Purchase:  If the closing  pursuant to the Stock  Purchase
Agreement  has not occurred on or before July 15, 1998,  or if prior to July 15,
1998,  the  Stock  Purchase  Agreement  is  terminated  in  accordance  with the
provisions of Section 13.11 thereof, Genpharm may deliver a notice in writing to
Resources  on or  before  July  31,  1998 and  thereupon  this  agreement  shall
immediately  terminate in respect of those Products for which Product  Approvals
have not been  received by Genpharm or its  Affiliate on or before July 15, 1998
or the date upon which the Stock Purchase Agreement is terminated,  whichever is
earlier,  and shall  terminate  in  respect of all other  Products  on the first

(or  terminates  this  agreement in respect of a particular  Product or Products
only) pursuant to Section 10.2,  10.3 or 10.8 hereof or if Resources  terminates

Competing  Products to any  Product(s)  as to which this  agreement  has been so
terminated  for a period  of 24  months  following  the  effective  date of such
termination.

                                       28


10.11 Non-Compete Obligation of Genpharm: If Resources terminates this agreement
(or  terminates  this  agreement in respect of a particular  Product or Products
only) pursuant to Section 10.3 hereof or if Genpharm  terminates  this agreement

                  by Resources or any of its Affiliates (but in any event within
                  5 days of receipt thereof, except in the case of a Serious ADE
                  [as  defined  below] in which  event  Resources  shall  notify
                  Genpharm and the  Manufacturer of same within 24 hours,  which
                  latter  notification  shall be by  telephone  with a facsimile
                  confirmation immediately following; or

         (ii)     of any FDA complaints or complaints of any other  governmental
                  or regulatory body, agency or official in the Territory within
                  48 hours, except on weekends and holidays.

         For  purposes  of this  agreement  "Serious  ADE" shall mean an adverse

         congenital  abnormality  or  serious  laboratory  abnormality  which is

         relevant clinical signs or symptoms. Genpharm shall, or shall cause the
         applicable  Manufacturer  to, notify Resources in the manner and within
         the time periods hereinbefore  contemplated of any ADE or FDA complaint
         (or of the complaint of any  governmental  body,  agency or official in
         the  Territory)  relating to such  Product in respect of the  Territory
         following their receipt by Genpharm or such Manufacturer.

(b)      Genpharm shall be responsible for filing or causing the Manufacturer to

         Manufacturer  with a copy  of any  correspondence,  reports,  or  other

                                       31


         documents  relating to a complaint  or ADE received by Resources or its
         Affiliate  relating to the Product  promptly of the receipt thereof and
         shall  also  provide to  Genpharm  (and such  Manufacturer)  Resources'
         response  thereto within a reasonable  period  following  generation of
         such  document by  Resources.  Upon the request of Genpharm,  Resources
         shall use reasonable commercial efforts to retrieve and shall cause its
         Affiliates  to use  reasonable  commercial  efforts  to  retrieve  such
         samples of the Product  which are the object of a  complaint  or ADE to
         enable  Genpharm  and/or the  applicable  Manufacturer  to conduct such
         tests,  studies and  investigations as it determines to be necessary to
         respond  to such ADE or  complaint  or to take  appropriate  corrective
         action.

11.7     Recalls:

(a)      In the event that  Genpharm or a  Manufacturer  shall be  required  (or
         shall voluntarily  decide) to initiate a recall,  product withdrawal or
         field  correction  of any  Product  (a  "Recall"),  whether or not such
         Recall  has  been  requested  or  ordered  by the  FDA  (or  any  other
         governmental  body,  agency  or  official  having  jurisdiction  in the
         Territory) or by a court, Genpharm shall, or shall cause the applicable
         Manufacturer  to, notify Resources and Resources shall fully co-operate
         and shall cause its Affiliates to fully  co-operate  with Genpharm (and
         such  Manufacturer)  in  notifying  their  customers to return all such
         Product and shall  follow any other  instructions  provided by Genpharm
         (or such Manufacturer).

(b)      In the event that  Resources  believes  that a Recall may be  necessary
         and/or  appropriate,   prior  to  taking  any  action  Resources  shall
         immediately  notify  Genpharm  and  the  applicable   Manufacturer  and
         Genpharm and  Resources  shall  co-operate  and cause their  respective
         Affiliates to co-operate with each other (and the other's Affiliate) in
         determining the necessity and nature of the action to be taken.

(c)      With respect to any Recall, Genpharm or the Manufacturer shall make all
         contacts with the FDA and shall be responsible for co-ordinating all of
         the necessary  activities in connection  with such Recall and Resources
         (and its  Affiliates)  and  Genpharm  (and its  Affiliate)  shall  each
         co-operate with the other (and with the other's Affiliate) in recalling
         the affected Product.

(d)      In the event that it is  determined  by  agreement of the parties or by
         arbitration  as herein  contemplated  that a Recall results solely from
         any cause or event arising from the  manufacture,  labelling,  storage,
         handling,  or packaging of the Product by Genpharm or a Manufacturer or
         other  cause or  event  attributable  to  Genpharm  or a  Manufacturer,
         Genpharm shall be responsible  for all expenses of such Recall.  In the
         event  that  it  is  determined  by  agreement  of  the  parties  or by
         arbitration  as herein  contemplated  that a Recall results solely from
         any cause or event arising from the  transportation,  manufacturing (if
         applicable),  repackaging,  labelling,  storage, handling, marketing or
         distribution  of the Product by Resources or any of its  Affiliates  or
         other  cause  or  event   attributable  to  Resources  or  any  of  its
         Affiliates,  Resources  shall be  responsible  for all expenses of such
         Recall.  If: 

                                       32


         (i)      within 60 days of the initiation of a Recall,  the parties are
                  unable to agree  that the cause of such  Recall was solely the
                  responsibility of Resources or its Affiliates or Genpharm or a
                  Manufacturer as hereinbefore contemplated; or

         (ii)     an arbitrator  pursuant to an arbitration  initiated by one of
                  the parties in respect of such Recall within the 60 day period
                  contemplated  in (i) above,  determines that the cause of such
                  Recall was not solely the  responsibility  of Resources or its
                  Affiliates or of Genpharm or a  Manufacturer  as  hereinbefore
                  contemplated;

         then  Resources  shall  initially  pay or  reimburse  Genpharm  and its
         Affiliates,  as the case may be,  for the  expenses  of the  Recall but
         shall be entitled to recover from Genpharm the Applicable Percentage of
         the  expenses so incurred  through  deductions  to and sharing of Gross
         Profits.

(e)      For purposes of this agreement,  Recall expenses shall include, but not
         be limited to, the expenses of  notification  and destruction or return
         of the recalled  Product,  as the case may be, and Resources'  (and its
         Affiliates')   and   Genpharm's   and   its   Affiliates'    reasonable
         out-of-pocket  costs in connection  with such Recall  including but not
         limited to  reasonable  attorney's  fees and  expenses  and credits and
         recall expenses claimed and paid to customers (the "Recall  Expenses").
         Each of the parties  shall use, and shall cause its  Affiliates to use,
         its  reasonable  best efforts to minimize the Recall  Expenses which it
         incurs  and  shall  provide  to the  other,  upon  request,  reasonable
         evidence of the out-of-pocket  expenses being claimed by it. The direct
         out-of-pocket costs and expenses of the Recall contemplated above shall
         not include the gross amount invoiced by Resources or its Affiliates to
         the customers on the sale of the Product  recalled,  which amount shall
         be dealt with in  accordance  with the  provisions  of Sections 8.2 and
         shall also not  include  any Excess  Reprocurement  Costs  (within  the
         meaning of Section 8.3 hereof),  which costs shall be paid by Resources
         (subject to its right to partially  recover same through deduction from
         Gross Profits).

(f)      All Product recalled  pursuant to this Section 11.7 shall be treated as
         Product  returned to Resources by its customers  and the  provisions of
         Section 8.2 shall apply thereto.

(g)      All communications relating to a Recall shall be held in confidence and
         shall be subject to the terms of Article 12 hereof.


                                   ARTICLE 12
                                 CONFIDENTIALITY


12.1 Confidential  Nature of Agreement:  Each of the parties hereto agrees that,
without the prior written  consent of the other, or except as may be required by

                                       33


law or court  order,  the  existence  and terms of this  agreement  shall remain
confidential  and shall not be disclosed to any Person other than  employees and
professional  advisers of such party or its  Affiliate  who  reasonably  require
knowledge of the existence or terms of this  agreement and who are bound to such
party or its Affiliate by a like obligation of  confidentiality.  Such employees
and advisors will be advised of the nature and existence of the  confidentiality
undertakings of this agreement and of the  applicability of such undertakings to
them and will agree to be bound hereby.  

12.2 Duty of  Confidentiality:  Each of Genpharm and Resources agrees to hold in
trust  and  confidence  (and to  cause  its  Affiliates  to hold  in  trust  and
confidence)  for the  benefit  of the  other  party  (and  its  Affiliates)  all
Confidential Information of such other party and its Affiliates and each further
agree to safeguard,  and to cause its Affiliates to safeguard,  the Confidential
Information  of the other (or its  Affiliates)  to the same  extent that it does
with its own confidential  information and to limit and control copies, extracts
and  reproductions  made of such Confidential  Information.  Neither party will,
without the express  written consent of the other,  directly or indirectly,  use
(or authorize,  permit or suffer any of its Affiliates to use) any  Confidential
Information  of the other party or of its  Affiliates for any purpose other than
to implement the provisions of this agreement or in regulatory proceedings or in
litigation.  Neither party will disclose Confidential Information to any Person,
other than its employees or other representatives or those of its Affiliates who
have a need to know to  fulfill  the  provisions  and  intent of this  agreement
(where such  provisions  and intent  cannot  properly be fulfilled  without such
disclosure)  and who  have  been  informed  of the  confidential  nature  of the
information  and have agreed to be bound by the terms  hereof.  Each of Genpharm
and  Resources  shall  use its  best  efforts  to  prevent  unauthorized  use or
disclosure of the  Confidential  Information  of the other or its Affiliates and
shall use protective measures no less stringent than those used by it in its own
business to protect its own confidential information, including segregating such
information  at all  times  from the  confidential  material  of others so as to
prevent any commingling.

12.3 Compulsory Disclosures:  In the event that either Genpharm or Resources (or
any of their respective  Affiliates) shall be legally compelled or required by a
court of competent  jurisdiction to disclose all or any part of the Confidential
Information of the other (or its Affiliates),  it shall provide prompt notice to
the other so that such other party (or its Affiliates) may determine  whether or
not to seek a protective order or any other appropriate  remedy. If a protective
order or other  appropriate  remedy is not obtained  before such  disclosure  is
required,  the party  required  to make  disclosure  will  disclose  only  those
portions of the  Confidential  Information  in  question  which it is advised by
written  opinion of counsel  (which opinion shall be addressed to such party and
to the other  party),  it is legally  required to disclose and will exercise its
best efforts to obtain reliable  assurances that confidential  treatment will be
accorded such Confidential Information.

12.4 Return of Confidential Information: Upon termination of this agreement each
of Genpharm and  Resources  shall  immediately  return to the other all material
containing  or reflecting or referring to any  Confidential  Information  of the
other party or its Affiliates (including all notes, summaries, analysis or other
documents  prepared  or derived  therefrom)  and all copies  thereof in any form
whatsoever  under the power or control of such party or its  Affiliates,  except
that one copy may be retained for legal archival purposes,  and such party shall

                                       34


delete such  Confidential  Information from all retrieval systems and data bases
or destroy  same as directed by the other party and furnish to the other  party,
if requested,  a certificate of a senior officer of such party  certifying  such
return,  deletion  and/or  destruction.  Where this  agreement is  terminated in
respect of a particular Product or Products only then the foregoing  obligations
shall thereupon apply to  Confirmation  Information  relating to such Product or
Products.

12.5 Survival: The obligations of confidentiality contained herein shall survive
the termination of this agreement.

                                   ARBITRATION


13.1 Arbitration:  Any controversy or claim arising out of, or relating to, this
agreement or the breach  thereof  shall be referred for decision  forthwith to a
senior  executive of each party not involved in the dispute.  If no agreement is
reached  within  30 days of the  request  by one party to the other to refer the
same to such senior  executive,  then such controversy or claim shall be settled
by  arbitration  in  accordance  with the  Commercial  Arbitration  Rules of the

general postal disruption (whether as a result of rotating strikes or otherwise)
in the  country or  territory  where the  sender or the  intended  recipient  is
situated then such notice shall not become  effective until the 5th business day
following the date of resumption of normal mail service.

Where  Resources is  authorized  or required to notify or otherwise  communicate

14.2  Force  Majeure:  Neither  party  shall be  considered  to be in default in
respect of any obligation  hereunder if failure of  performance  shall be due to
Force Majeure (as hereinafter  defined).  If either party is affected by a Force
Majeure event such party shall, within 20 days of its occurrence, give notice to
the other party stating the nature of the event,  its  anticipated  duration and
any action  being  taken to avoid or  minimize  its effect.  The  suspension  of
performance shall be of no greater scope and no longer duration than is required
by such  Force  Majeure  and the  non-performing  party  shall use  commercially
reasonable  efforts to remedy its  inability to perform.  The  obligation to pay
money in a timely  manner is  absolute  and shall  not be  subject  to the Force
Majeure  provisions,  except to the extent payment is prohibited by governmental
rule or regulations  other than rules or  regulations  incident to bankruptcy or
insolvency  proceedings of a party. Force Majeure shall mean an unforeseeable or
unavoidable cause beyond the control and without the fault or negligence of a

shall,  after  the  passage  of 120 days,  have the  option  to  terminate  this

the parties and their respective successors and permitted assigns.

Chief Financial Officer of Genpharm or, at Genpharm's  option,  the Manufacturer
of such Product  certifying that, to the best of his knowledge,  information and
belief,  after reasonable  investigation,  such statement is true and correct in

                  consideration  of such  customer's  agreement  to purchase any
                  service or any  product  other than the  Product  unless  such
                  rebates or discounts are across-the-board rebates or discounts
                  applied  uniformly  to  the  Product  and  other  products  or
                  services as part of an overall program of rebates or discounts

                  incurred  by  Resources  or its  Affiliates  in the  period to

         (iii)    payments   made   by   Resources   and  its   Affiliates   for
                  administrative fees,  reimbursements or similar payments to or

                  purchase or utilization of the Product;

         (iv)     Deductible  Listing Fees paid by  Resources or its  Affiliates
                  which are applicable to the period.

It is understood and agreed that:

         accordance with generally accepted accounting principles;

         invoiced or other revenue  recognized  are for actual credits issued or
         payments  made by  Resources  and  its  Affiliates  and do not  include
         amounts  accrued,  provided  or reserved  for  estimated  or  potential
         deductions;

(c)      the deduction  under (i) above from the gross amount  invoiced or other
         revenue  recognized  shall not  include  any Recall  Expenses or Excess

         provisions  of Sections 8.2 or 8.3 hereof or the  definition  of "Gross
         Profit");

(d)      no amount  shall be  deducted  under (i),  (ii),  (iii),  (iv) above or

         account of or as an  allowance  for a bad debt or  doubtful  account in
         relation to Product sold by Resources or its Affiliates;

(e)      no amount shall be deducted under (i), (ii),  (iii),  (iv) or otherwise
         from the  gross  amount  invoiced  or other  revenue  recognized  where
         Resources  has the right to recover  the amount  paid or  credited to a
         customer or other Person from Genpharm  pursuant to this agreement and,
         if any amount  previously  claimed as such deduction in calculating Net
         Sales in one period is  subsequently  recovered or becomes  recoverable
         from Genpharm in another period the amount so recovered  shall be added
         to the Net Sales in the  period  in which it is  recovered  or  becomes
         recoverable from Genpharm, it being the intention of the parties hereto
         that  Resources  shall not have the right to recover  the same  expense
         directly  from  Genpharm  and again  through the  calculation  of Gross
         Profits hereunder;

(f)      no credit or payment to an  unrelated  third  party  customer  shall be
         deducted  under (i) from the gross  amount  invoiced  or other  revenue
         recognized  where such  credit or payment is an attempt to  directly or
         indirectly  circumvent the restrictions or limitations contained herein
         as to  the  nature  or  quantum  of the  items  which  may be  deducted
         hereunder  in  calculating   Net  Sales  nor  shall  Resources  or  its
         Affiliates  reduce the selling price at which the Product is sold to an
         unrelated  third  party  customer  with a view  to  circumventing  such
         restrictions or limitations; and

(g)      in respect of transfers of Product by Resources to its  Affiliates  (or
         between  Affiliates)  for resale,  the price at which such products are
         resold by such Affiliate to third parties (other than other Affiliates)
         shall be  included  in Gross  Profits and the  transfer  price  between
         Resources  and  its  Affiliates  or  between  such  Affiliates  will be
         disregarded.
