          requirements.  If PAR rejects a shipment before the date on which
          payment therefor is due according to Paragraph 2.6 hereof, it may
          withhold payment for that shipment or the rejected portion thereof.
          All shipments or portions thereof not rejected by PAR before such date
          shall be paid for in accordance with Paragraph 2.6 hereof.  All
          shipments or portions thereof which PAR rejected but, as determined
          pursuant to Paragraph 3.4 hereof, did not have the right to reject,
          shall be paid within fifteen (15) days following the day on which such
          determination was made, unless PAR had paid earlier.  In the event PAR
          rejects a shipment or portion thereof within such thirty (30) day
          period in accordance with the terms hereof but after payment therefor
          had been made, PAR shall be entitled to recoup the payment amount by,
          at PAR's election, MOVA's issuing a prompt refund or by PAR's
          offsetting such amount against the payment of future invoices or other
          payments that may become due hereunder.  The representations and
          warranties given by MOVA hereunder shall survive any failure to reject
          by PAR under this Paragraph.

          3.3  Recalls.  If the Product is recalled pursuant to FDA regulation
               -------                                                        
          or other applicable laws and returned as a result of any such recall
          and such recall is due to MOVA's negligence or willful misconduct or a
          breach of any representation or warranty of MOVA hereunder, then MOVA
          shall bear all incremental out-of-pocket direct costs in connection
          with the recall, including, but not limited to, all notification
          letters and all shipping expenses.  In no event shall MOVA be
          responsible for any indirect expenses incurred by PAR.  If the
          recalled Product is to be destroyed, MOVA, at PAR's request, shall
          replace free of charge said Product or issue a credit to PAR's account
          or refund payment to PAR.  If the recalled Product is to be reworked,
          MOVA shall bear all costs of reworking said

 
                                                                               7

          product.  If the Product is recalled and such recall is due to PAR's
          negligence or willful misconduct or a breach of any representation or
          warranty of PAR hereunder, then PAR shall bear all incremental out-of-
          pocket direct costs in connection with the recall, including, but not
          limited to, all notification letters and all shipping expenses.  In no
          event shall PAR be responsible for any indirect expenses incurred by
          MOVA.

          3.4  Disputes.  If MOVA disputes PAR's right to reject all or part of
               --------                                                        
          any shipment of the Product as set forth in Paragraph 3.2 or 3.3
          hereof, such dispute shall be resolved by an independent approved FDA
          testing organization or consultant of recognized repute within the
          U.S. pharmaceutical industry mutually agreed upon by the parties, the
          appointment of which shall not be unreasonable withheld or delayed by
          either party.  The determination of such entity with respect to all or
          part of any shipment of the Product shall be final and binding upon
          the parties, but only as to the reasons given by PAR in rejecting the
          shipment or portion thereof and shall have no effect on any matter for
          which said entity did not render a determination.  The fees and
          expenses of the third party making the determination shall be paid by
          the party against which the determination is made.

          3.5  Obligation to Inform the Other.  Parties agree to keep each other
               ------------------------------

          whether received directly or indirectly, which might in any way affect
          the marketability, safety or effectiveness of the Product, or which
          might result in potential liability for either party, or which might
          necessitate action on the part of either party, or which might result
          in recall of the Product, or which might otherwise in any way affect
          either of the parties' interest with respect to the distribution or
          use of the Product.  Nothing contained in this Paragraph shall
          obligate either party to provide the other with any information other
          than information regarding the quality of the Product.

          3.6  Inspections.  Upon reasonable notice given to MOVA, PAR shall
               -----------

          any facility at which the Product to be sold to PAR hereunder is

          3.7  Packaging.  MOVA shall supply the Product to PAR in bulk and in
               ---------

                                                                               9

                             ARTICLE 5 - APPROVALS
                             ---------------------

          5.1  ANDA.  MOVA shall be responsible for obtaining the approval of
               ----                                                          
          the ANDA by the FDA and in so doing shall exercise what it in good
          faith believes to be reasonable commercial effort to obtain such
          approval at the earliest possible date.

          5.2  Inspections by Government Agencies.  Without limiting the
               ----------------------------------                       
          generality of Paragraph 5.1 hereof, MOVA shall permit the FDA to

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

          6.1  Price Protection.  Notwithstanding any provision herein to the
               ----------------                                              
          contrary, if at any time MOVA makes sales of the Product to any other
          party within the USA or for resale in the USA, except sales to
          federal, state and local government agencies, at a price lower than
          one hundred twenty-five percent (125%) of the Base Price to PAR then
          in effect under this Agreement,  the Base Price to PAR then in effect
          under this Agreement shall be reduced to eighty percent (80%) of such
          lower price given to the other party for so long as MOVA continues to
          make such sales to such other party at such lower price, unless sale
          to PAR at such lower price would violate the provisions of any
          pertinent law, order or regulation.

          6.2  Adjustment.  In the event that PAR's average selling price for
               ----------                                                    
          the Product to any other party becomes less than [     ] per bottle of
          100 tablets for 300 mg tablets adjusted on January 1st. every year,
          commencing on January 1, 1995 for the annual change in the CPI (with
          comparable limits for other strengths as set forth in Exhibit A), the
          parties shall negotiate such modification to this Agreement as may be
          necessary to enable each to perform thereunder on terms fair and
          reasonable under the circumstances and if no agreement thereon can be
          reached within a reasonable time, either party may terminate this
          agreement by giving ninety (90) days prior notice.

 
                                                                              10

          6.3  Independent Prices.  Each of the parties shall establish the
               ------------------                                          
          prices at which it sells the Product to its customers independently of
          the other party.

          6.4  Active Ingredient Cost Fluctuations.  In the event that the cost
               -----------------------------------                             
          of the Active Ingredient purchased from third parties by MOVA, as
          defined in Exhibit A, increases or decreases by more than 10% at any
          time, such change shall be added or deducted to the Base Prices paid
          by PAR to MOVA according to Paragraph 2.6 hereof.  MOVA shall provide
          PAR with the necessary information to verify the changes in the cost
          of the Active Ingredient.


                          ARTICLE 7 - INDEMNIFICATION
                          ---------------------------

          7.1  MOVA's Obligation to Indemnify.  MOVA agrees to indemnify,
               ------------------------------                            
          defend, and hold harmless PAR, its affiliates and subsidiaries and
          their respective employees against any and all claims, losses, damages
          and liabilities, including reasonable attorneys' fees and costs
          associated with a recall of the Product as defined in Paragraph 3.3
          hereof, incurred by any of them arising out of any breach of any
          obligation hereunder or any representation or warranty by MOVA
          hereunder or any act or omission of MOVA in connection with its
          obligations hereunder.

          7.2  PAR's Obligation to Indemnify.  PAR agrees to indemnify, defend
               -----------------------------                                  
          and hold harmless MOVA, its affiliates and subsidiaries and their
          respective employees against any and all claims, losses, damages and
          liabilities, including reasonable attorneys' fees and costs associated
          with a recall of the Product as defined in Paragraph 3.3 hereof,
          incurred by any of them arising out of any breach of any obligation
          hereunder or any representation or warranty by PAR hereunder or any
          act or omission of PAR in connection with its obligations hereunder.

          7.3  Obligations of the Party Seeking to be Indemnified. If PAR or any
               ---------------------------------------------------              
          of its affiliates or subsidiaries or MOVA or any of its affiliates or
          subsidiaries (in each case an "Indemnified Party") receive any written
          claims which it believes is the subject of indemnity hereunder by MOVA
          or PAR, as the case may be (in each case an "Indemnifying Party"), the
          Indemnified Party shall, as soon as reasonably practicable after
          forming such belief, give notice thereof to the Indemnifying Party,
          including full particulars of such claim to the extent known to the
          Indemnified Party; provided, that the failure to give timely notice to
          the Indemnifying Party as contemplated hereby shall not release the
          Indemnifying Party from any liability to the Indemnified Party except
          to the extent that the Indemnifying Party is injured by such delay.
          The Indemnifying Party shall have the right, by prompt notice to the
          Indemnified Party, to assume the defense of such claim with counsel
          reasonably satisfactory to the Indemnified Party, and at the cost of
          the Indemnifying Party.  If the Indemnifying Party does not assume the

 
                                                                              11

          defense of such claim, or, having done so, does not diligently pursue
          such defense, the Indemnified Party may assume such defense, with
          counsel of its choice, but for the account of the Indemnifying Party.
          If the Indemnifying Party so assumes such defense, the Indemnified
          Party may participate therein through counsel of its choice, but the
          cost of such counsel shall be for the account of the Indemnified
          Party.  The party not assuming the defense of any such claim shall
          render all reasonable assistance to the party assuming such defense,
          and all out-of-pocket costs of such assistance shall be for the
          account of the Indemnifying Party.  No such claim shall be settled
          other than by the party defending the same, and then only with the
          consent of the other party, which shall not be unreasonably withheld;
          provided, that the Indemnified Party shall have no obligation to
          consent to any settlement of any such claim which imposes on the
          Indemnified Party and liability or obligation which cannot be assumed
          and performed in full by the Indemnifying Party.

          7.4  Insurance.  Each party and its Affiliates shall carry products
               ---------                                                     
          liability insurance in an amount at least equal to [     ] with an
          insurance carrier reasonably acceptable to the other party.  Such
          insurance shall cover the indemnifications set forth in Article 7
          hereof.  Each party shall name the other party as additional insured
          under such policy.  A copy of such policy or policies shall be
          delivered to the other party within ten (10) days prior to the date
          any such Product is first commercially sold by such party, and shall
          provide among other things, that such insurance shall not be canceled
          or modified without giving the other party at least thirty (30) days
          prior written notice.

                          ARTICLE 8 - CONFIDENTIALITY
                          ---------------------------

          8.1 Each party shall at all times maintain as confidential any know-
          how or other business information received from the other party under
          this Agreement during the term of this Agreement, shall only use such
          information in furtherance of this Agreement shall only disclose such
          information to those of its employees with a need to know in
          furtherance of this Agreement, provided, however, that nothing

          contained herein shall prevent a party from submitting information to
          a governmental instrumentality in connection with seeking approval to
          market the Product.  Said obligation of confidentiality shall not
          apply, however, to any information which:

               (a) was known to the receiving party, as evidenced by its written
               records, prior to receipt from the other party;

               (b) is in the public domain at time of receipt or subsequently
               enters the public domain through no breach of this Agreement by
               the receiving party;

               (c) after the date of receipt from the disclosing party, is
               received without

 
                                                                              12

          cover of secrecy from a third party with a bona fide right to disclose
          without violating any right of the disclosing party; or

               (d) is independently developed by the receiving party without the
               aid, application or use of any information for which it is
               obligated to maintain as confidential according to this
               Paragraph.

          The respective obligations of MOVA and PAR under this Paragraph shall
          be in effect during the term of this Agreement and for the  three (3)
          years thereafter.
