                                 INDEMNIFICATION

      7.1 Indemnification by Alliance. Alliance agrees to indemnify, defend and
hold harmless PFC, its affiliates and their respective employees against any and
all third party claims, including claims made against PFC by any of its
distributors, losses, damages and liabilities, including reasonable attorney's
fees, incurred by any of them arising out of any breach of any obligation by
Alliance hereunder or any misrepresentation by Alliance hereunder or any
negligent or intentionally wrongful act or omission by Alliance in connection
with its manufacturing and supply services hereunder. Alliance shall not be
responsible for indemnifying PFC against claims for lost profits, consequential
or indirect damages with respect to the Product.

      7.2 Indemnification by PFC. PFC agrees to indemnify, defend and hold
harmless Alliance, its affiliates and their employees against any and all
third-party claims, losses, damages and liabilities, including reasonable
attorney's fees, incurred by any of them arising out of any breach of any
obligation by PFC hereunder or any misrepresentation by PFC hereunder or any
negligent or intentionally wrongful act or omission of PFC in connection with
the Product.

      7.3 Procedure. If PFC, its affiliates or their respective employees, or
Alliance, its affiliates or their respective employees (in each case an
Indemnified Party) receive any written claim which such Indemnified Party
believes is the subject of indemnity hereunder by Alliance or PFC 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; 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 unless the Indemnifying party
demonstrates that the defense of such claim is prejudiced by such failure. The
Indemnifying Party shall have the right, by prompt notice to the Indemnified
Party, to assume the defense of such claim, at its cost, with counsel reasonably
satisfactory to the Indemnified Party. If the Indemnifying Party does not so
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 at the cost of the Indemnifying Party. If the Indemnifying Party so
assumes such defense, it shall have absolute control of the conduct of the
litigation; the Indemnified Party may, nevertheless, participate therein through
counsel of its choice and at its cost. 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 any liability or obligation which cannot be
assumed and performed in full by the Indemnifying Party.

or elsewhere, shall comply with the provisions of the United States Food, Drug
and Cosmetic Act, and such Product shall not, when delivered, be adulterated or
misbranded within the meaning of the United States Food, Drug and Cosmetic Act.

<PAGE>

provisions of a country in the Territory are different from those of the United

shipped by PFC in accordance with the Specifications.

for compliance with Specifications prior to release and shipment to PFC or its
designee. After receipt PFC or its designee shall test and inspect, as PFC or

Specifications. If within forty-five (45) days after receipt of a lot of Product
PFC or its designee notifies Baxter in writing that such lot does not meet the
Specifications as determined by PFC's or its designee's testing and inspection
of the Product, Baxter shall replace the Product (subject to Section 4.3 below)
at Baxter's expense (such expense to include the cost of Components and
Materials) within forty-five (45) days of such notice. Baxter shall pay for
shipping charges to deliver such replacement Product to PFC or its designee. A

(1) be returned to Baxter within a reasonable period of time or (2) be destroyed
by PFC at Baxter's expense.

      4.3 Disputes with Respect to Rejection. If Baxter disputes PFC's right to
reject all or part of any shipment of the Product as set forth in Section 4.2
hereof, and such dispute is not resolved by mutual agreement between the parties
within sixty (60) days of PFC's notice of rejection, such dispute shall be
resolved by an independent FDA approved 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 unreasonably withheld or
delayed by either party. The determination of such testing 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 PFC 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.

any proposed change to Materials or Components of the Product, process
specifications and/or controls, as well as third party contractors, equipment or

harmless PFC, its affiliates and their respective employees against any and all
third party claims, including claims made against PFC by any of its
distributors, losses, damages and liabilities, including reasonable attorney's

Baxter hereunder or any misrepresentation by Baxter hereunder or any negligent
or intentionally wrongful act or omission by Baxter in connection with its
manufacturing and supply services hereunder. Baxter shall not be responsible for
indemnifying PFC against claims for lost profits, consequential or indirect
damages with respect to the Product.

negligent or intentionally wrongful act or omission of PFC in connection with
the Product.

      7.3 Procedure. If PFC, its affiliates or their respective employees, or
Baxter, its affiliates or their respective employees (in each case an
Indemnified Party) receive any written claim which such Indemnified Party
believes is the subject of indemnity hereunder by Baxter or PFC 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; 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 unless the Indemnifying party
demonstrates that the defense of such claim is prejudiced by such failure. The
Indemnifying Party shall have the right, by prompt notice to the Indemnified
Party, to assume the defense of such claim, at its cost, with counsel reasonably
satisfactory to the Indemnified Party. If the Indemnifying Party does not so
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 at the cost of the Indemnifying Party. If the Indemnifying Party so
assumes such defense, it shall have absolute control of the conduct of the
litigation; the Indemnified Party may, nevertheless, participate therein through
counsel of its choice and at its cost. 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 any liability or obligation which cannot be
assumed and performed in full by the Indemnifying Party.
