representations and warranties given by MOVA in Article 4 hereof.  Each
shipment of the Product shall be accompanied by a quality assurance
analytical data sheet (the "Q.A. Certificate of Analysis").

fails to conform to the applicable specifications or otherwise fails to
conform to the representations and warranties given by MOVA herein, by
giving written notice to MOVA specifying the manner in which all or part of
such shipment fails to meet the foregoing 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

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

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 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.

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.

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.

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

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

the provisions of any pertinent law, order or regulation.

party.

6.4  Active Ingredient Cost Fluctuations.  In the event that the cost of
     -----------------------------------

                     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 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

     application or use of any information for which it is obligated to
     maintain as confidential according to this Paragraph.
