2.01 The Specifications may be changed at any time by mutual agreement of the
     parties.  Any disagreement concerning revisions to the Specifications shall

SECTION 3.  PRICE: PAYMENT

3.01 Customer agrees to compensate [*] for performing the Services in the
     amounts shown in Exhibit D.

3.02 Prices set forth in Exhibit D will be adjusted upwards for each subsequent
     contract year by any increase in the Producer Price Index during the twelve

     adjustments at least 60 days prior to the end of each contract year and
     will furnish Customer a revised Exhibit D to this Agreement.

3.03 [*] shall also be authorized to pass through any cost increases for raw
     materials and packaging components provided by [*] to the extent such
     increases would cause total cost of goods of finished Products to increase
     by more than 2%.  [*] will advise Customer in writing of any such cost
     increases quarterly at the time [*] confirms in writing Customer's purchase
     order.  Upon Customer's request, [*] will furnish supporting documentation
     therefor.

     Production as expressed in Section V thereof referenced in Exhibits B and C
     attached hereto.  For each batch of Product delivered to the Customer, [*]
     shall, concurrently with delivery of notice of Product completion pursuant

     by a third party acceptable to and at the shared expense of both parties,
     that any Product shipped by [*] hereunder does not conform with the
     Specifications, at the Customer's option, (i) [*] shall be relieved of any
     obligation to deliver any Product with respect to the non-conforming
     shipment and in such case [*] shall credit against future purchases by
     Customer the purchase price of such non-conforming Product paid by Customer
     together with any shipping costs paid by the Customer for delivery of such
     non-conforming Product, or (ii) [*] shall replace the non-conforming
     Product with substitute Product which conforms with said Specifications and
     any other requirements of this Agreement, within the time agreed to by both
     parties, in which case the Customer shall pay to [*] amounts in accordance
     with Section 3 hereof based on the substitute shipment.  The non-conforming
     Product shall become the property of and returned to [*] at [*]'s expense.
     [*] shall dispose of such Product at its own expense according to all
     appropriate regulations.

4.04 [*] shall substitute Product at no cost to the Customer to complete any
     Product recall required by subsequent determination that the Product was
     not produced in accordance with Specifications when released to the
     Customer or was not produced in compliance with applicable USDA
     regulations.  The Customer shall be responsible for all other recalls.

4.05 [*] shall promptly communicate in writing to Customer all inquiries or
     complaints about the Products made to [*] by customers of the Customer.

     dating may be accepted at the discretion of Customer.  Customer is
     responsible for the cost and handling of all outdated Products.

4.07 The remedies described in this Section 4 are exclusive and in lieu of any
     other remedy Customer would otherwise have against [*] with respect to
     defective Products or any breach of [*]'s warranty contained in Section
     1.02; provided, that this section shall not limit [*]'s indemnity
     obligation set forth in Section 13 with respect to third party claims.

     it will order from [*] during the first twelve (12) months of this

     Section 5.01 to [*], Customer will also furnish revised written estimates
     of the quantities it anticipates it will order during the succeeding twelve
     (12) month period.  The forecasts will not be deemed binding commitments,

12.02  [*] is and shall always remain an independent contractor in its
       performance of this Agreement. The provisions of this Agreement shall not
       be construed as authorizing or reserving to the Customer any right to
       exercise any control or direction over the operations, activities,
       employees, or agents of [*] in connection with this Agreement except to
       the extent required by law, it being understood and agreed that the
       control and direction of such operations, activities, employees, or
       agents shall otherwise remain with [*]. Neither party to this Agreement
       shall have any authority to employ any person as an employee or agent for
       or on behalf of the other party to this Agreement, nor any person
       performing any duties or engaging in any work at the request of such
       party, shall be deemed to be an employee or agent of the other party to
       this Agreement.

12.03  Law Governing and Venue:

       (a)  This Agreement shall be governed by and construed in accordance with
            the laws of the State of California (as to proceedings initiated by
            [*]) or [*] (as to proceedings initiated by Customer) as if the
            Agreement had been delivered in such State and all acts performed or
            required to be performed hereunder have been performed entirely
            within that State.

                                      -8-

     (b) Any dispute or controversy arising out of or relating to this
         Agreement, any document or instrument delivered pursuant to, or in
         connection with, or simultaneously with this Agreement; or any breach
         of this Agreement or any such document or instrument, shall be resolved
         (as to proceedings initiated by [*]) in San Diego, California, or (as
         to proceedings initiated by Customer) in [*].

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

12.05  No modification or waiver of any provision of this Agreement shall be
       effective unless the modification is made in writing and signed by both
       parties, and the same shall then be effective only for a period and on
       the conditions and for the specific instances and purposes specified in
       such writing. No course of dealing between [*] and the Customer or delay
       or failure to exercise any rights hereunder shall operate a waiver of
       such rights or preclude the exercise of any other rights hereunder.

12.06  Termination or expiration of this Agreement shall not relieve either
       party from any obligation under this Agreement which may have accrued
       prior thereto or which survives by its terms.

12.07  The captions set forth in this Agreement are for convenience only and
       shall not be used in any way to construe or interpret this Agreement.

12.08  Neither party to this Agreement may assign this Agreement or its rights
       or obligations hereunder without the prior written consent of the other
       party; except that either party may assign its rights and delegate its
       obligations hereunder without prior consent of the other party to any
       successor entity by way of merger, consolidation, or reorganization. Any
       permitted assignee shall assume all obligations of its assignor under
       this Agreement. No assignment shall relieve either party of
       responsibility for the performance of any accrued obligation which it has
       hereunder. Any consent required shall not be unreasonably withheld.

12.09  This Agreement (including the Exhibits hereto) constitute the entire
       understanding of the parties with respect to the subject matter hereof
       and supersede all prior negotiations or communications, however given,
       regarding the subject matter hereof. There are no other understandings,
       representations or warranties of any kind, express or implied.

12.10  Dispute Resolution, Arbitration:

     (a)  Customer and [*] agree that in the case of a dispute or difference of
          any kind, the parties in the first instance shall attempt to settle
          the dispute amicably.

          All disputes and differences of any kind arising under this Agreement,
          or arising between the parties including the existence or continued
          existence of this Agreement and the arbitrability of a particular
          issue which cannot be settled amicably by the parties shall be
          submitted to arbitration.  The arbitration shall be conducted in [*]
          (as to proceedings initiated by Customer) or San Diego, California (as
          to proceedings initiated by [*]), and shall be finally settled in
          accordance with the Rules of Arbitration of the American Arbitration
          Association in [*] (as to proceedings initiated by Customer) or San
          Diego (as to proceedings initiated by [*]) by one or more arbitrators
          appointed in accordance with the above-mentioned Rules.

          The decision of the arbitration tribunal shall be final and binding
          upon the parties and may be enforced in any court of competent
          jurisdiction, and no party shall seek redress against the other

                                      -9-
<PAGE>
 
          in any court or tribunal except solely for the purpose of obtaining
          execution of the arbitration award or of obtaining a judgement
          consistent with the reward.

     (b)  During any adjudication pursuant to Section (a) of this paragraph, the
          Customer and [*] shall continue to fulfill their respective
          obligations under this Agreement, unless the subject matter of the
          dispute is of such a nature that this is by no means possible until
          the dispute has been finally settled.

12.11  This Agreement is for the benefit of the parties hereto and is not
       intended to, and shall not be construed as benefitting or creating rights
       in any person or entity other than the signatories hereto.

12.12  [*] acknowledges and agrees that the legal remedies available to Customer
       in the event [*] violates the covenants and agreements made in this
       Agreement would be inadequate and that Customer shall be entitled,
       without posting any bond or other security, to temporary, preliminary and
       permanent injunctive relief, specific performance and other equitable
       remedies in the event of such a violation, in addition to any other
       remedies which Customer may have at law or in equity.


SECTION 13. INDEMNIFICATION

13.01  [*] hereby agrees to defend, indemnify and hold the Customer harmless
       against any and all expense, including reasonable attorneys fees and
       court costs, damages, claims and liabilities arising out of (a) any
       breach of warranty hereunder or material non-fulfillment or non-
       performance by [*] of any agreement, covenant or obligation of [*] under
       this Agreement; or (b) [*]'s failure to manufacture a Product in
       compliance with its Specifications.

13.02  The Customer hereby agrees to defend, indemnify and hold [*] harmless
       against any and all expense, including reasonable attorney fees and court
       costs, damages, claims and liabilities arising out of (a) a material non-
       fulfillment or non-performance by Customer of any agreement, covenant or
       obligation of Customer under this Agreement; (b) the use by the Customer
       or customers of the Customer of the Product, sale or distribution by the
       Customer of any of the Product which has been manufactured in compliance
       with the Specifications and (c) any alleged patent, trademark or
       copyright infringement.

13.03  In the event either party incurs, or expects to incur expenses, damages,
       claims, or liability for which it intends to seek indemnification from
       the other party, the party claiming indemnification (the "Indemnitee")
       shall promptly notify the other party (the "Indemnitor") and will permit
       the Indemnitor at the Indemnitor's sole discretion, to settle any such
       claim or suit and agrees to the complete control of such defense or
       settlement by the Indemnitor, and the Indemnitor shall not be responsible
       for any legal fees or other costs incurred other than as provided in the
       Agreement. The Indemnitee, its employees and agent(s) shall cooperate
       fully with the Indemnitor and its legal representatives in the
       investigation and defense of any claims or suits covered by the
       indemnification provisions of this Agreement.

13.04  [*] will maintain insurance in amounts meeting statutory requirements to
       protect [*] and the Customer from claims under any Worker's Compensation
       Acts and will maintain general comprehensive personal liability insurance
       in the minimum amount of $500,000 for any one occurrence to protect [*]
       and Customer from any other damages from personal injury, including
       death, which may be sustained by [*]'s agents, servants or employees and
       the general public and/or claims of property damage which might be
       sustained from any one of them due to the negligence of [*]. [*] shall,
       upon request, furnish the Customer a certificate of insurance.
