rights granted herein, upon the Effective Date of this Agreement, Nipro shall
pay to TheraSense a nonrefundable (except as provided for in Section 12.6.2),
noncreditable payment of Five Million U.S. Dollars (U.S. $5,000,000).

     3.2  TheraSense Product Prices.

right to *** revise the Transfer Prices with *** advance written notice to

requirements of Strips (as defined in Exhibit A) for the upcoming calendar year
(the "Estimated Annual Volume"). The Estimated Annual Volume shall be used to
establish the Transfer Price for the Strips for the first quarter of the
upcoming year. Thereafter, upon Nipro's submission of each quarterly forecast to
TheraSense, if either party concludes that the annual purchase of Strips will be
higher or lower than the Estimated Annual Volume so as to cause a different
Transfer Price to obtain, the parties will agree on a price change for Strips
for future shipments in such quarter. The objective of each quarterly price
change will be to minimuze year-end credits or rebates between the parties.

market price for Strips in the Territory may change up or down as a result of
changes in the Japan government reimbursement policies. Nipro shall promptly
inform TheraSense in writing, documenting any such changes in the reimbursement
policies for hospital or clinic blood glucose testing which would affect the
price Nipro would actually receive for sales of Strips. ***.

however, that in such event, solely for purposes of Section 12.6.2, the date of
termination shall be considered to be the date the injunction is effective (as
such date may be extended by any stay or appeal of such injunction).

10.  CONFIDENTIALITY

(5) years after the disclosure of any Confidential Information by one (1) of the
parties to the other hereto pursuant to this Agreement, the receiving party
shall keep completely confidential and shall not publish or otherwise disclose
and shall not use for any purpose except for the purposes contemplated by this
Agreement such Confidential Information, except that to the extent that it can
be established by the receiving party by competent proof that such Confidential
Information:

an obligation of confidentiality, at the time of disclosure;

                 (b)  was generally available to the public or otherwise part of

hereunder, provided that if a party is required to make any such disclosure of
another party's confidential information, other than pursuant to a

11.  INDEMNITY; INSURANCE; LIMITATION OF LIABILITY

     11.1  Indemnification of Nipro.
           ------------------------

           11.1.1  TheraSense shall indemnify, defend, and hold harmless Nipro
and its directors, officers and employees (each an "Nipro Indemnitee") from and
against any and all liabilities, damages, losses, costs or expenses (including
attorneys' and professional fees and other expenses of litigation and/or
arbitration) (a "Liability") resulting from a claim, suit or proceeding made or
brought by a third party against a Nipro Indemnitee arising from defects in
materials, workmanship, design or packaging of the FreeStyle Products, except
for matters for which Nipro is to indemnify TheraSense pursuant to Section
11.2.1.

           11.1.2  TheraSense shall defend, or at its option settle, any claims
brought against Nipro by third parties as a result of any infringement by the
FreeStyle Products of any U.S. or foreign patent, trade name, trademark, service
mark or copyright existing under the laws of the Territory, and shall reimburse
Nipro for any judgments, damages, cost or expenses payable by Nipro to a party
bringing such action together with reasonable attorneys' fees relating thereto.
If the FreeStyle Products, or any part thereof, are, or in the opinion of
TheraSense become, the subject of any claim for infringement of such third party
patent, trademarks, or copyrights, or if it is adjudicatively determined that
the FreeStyle Products, or any part thereof, infringe any such third party
patent trademark, or copyright, then

                                      -30-
<PAGE>

TheraSense may, at its option and expense, either (i) procure for Nipro the
right under such third party patent, trademark or copyright to sell or use, as
appropriate, the FreeStyle Products (or in the case of trademark infringement,
substitute a different trademark) or (ii) replace or modify the FreeStyle
Products or parts thereof in Nipro's possession, with other suitable and
reasonably equivalent technology or parts so that the FreeStyle Products become
non-infringing or (iii) if it is not commercially reasonable to take the actions
specified in items (i) or (ii) immediately preceding, terminate this Agreement
with ninety (90) days written notice.

               11.1.3 Notwithstanding the provisions of Section 11.1.2 above,
TheraSense assumes no liability for (i) infringements relating to any assembly,
circuit, combination, method or process made by anyone other than by or on
authority of TheraSense in which any of the FreeStyle Products may be used where
the FreeStyle Products when used alone would not result in such an infringement;
(ii) infringements involving the modification or servicing of the FreeStyle
Products, or any part thereof, done by anyone other than by or on authority of
TheraSense unless such modification or servicing was done by TheraSense; (iii)
any trademark infringements involving any marking or branding of the FreeStyle
Products not applied by TheraSense or at the request of TheraSense or involving
any marking or branding applied at the request of Nipro or any marking or
branding with Nipro or Kissei's trademarks; or (iv) modification of any
FreeStyle Products other than with TheraSense's written consent.

               11.1.4 The foregoing provisions of this Section 11.1 state the
entire liability and obligations of TheraSense, and the exclusive remedy of
Nipro and its Customers, with respect to any alleged product liability claim or
other matter covered by Section 11.1.1 related to the FreeStyle Products, or any
alleged infringement of any patents, copyrights, trademarks or other
intellectual property rights by the FreeStyle Products or any part thereof.

          11.2   Indemnification of TheraSense.
                 -----------------------------

                 11.2.1 Nipro shall indemnify, defend and hold harmless
TheraSense and its directors, officers, employees and agents and the successors
and assigns of any of the foregoing (each a "TheraSense Indemnitee") from any
and all claims, losses, costs, liabilities or expenses (including, without
limitation, attorneys' fees and other expenses of litigation) (a "Liability")
resulting from a claim, suit or proceeding made or brought by a third party
against a TheraSense Indemnitee arising out of (a) defects in the FreeStyle
Products sold by Nipro resulting from any action of Nipro, its Affiliates and
their Subdistributors, (b) FreeStyle Products claims, whether written or oral,
made by Nipro in its advertising, promotion, sale, or distribution of any of the
FreeStyle Products beyond those made by TheraSense, (c) the labeling, packaging,
storage or other handling, distribution or sale of the FreeStyle Products by
Nipro, its Affiliates or its Subdistributors except to the extent required by
TheraSense pursuant to this Agreement, or (d) any claim alleging noncompliance
by Nipro with Japan laws and regulations in the Territory which are equivalent
to the U.S. FDC&A.

                 11.2.2 Nipro shall defend, or at its option settle, any claims
brought against TheraSense by third parties as a result of any infringement by
the FreeStyle Products of any U.S. or foreign trademark, trade name, or service
mark existing under the laws of the Territory, and shall reimburse TheraSense
for any judgments, damages, cost or expenses payable by TheraSense to a party
bringing such action together with reasonable attorneys' fees relating thereto
as a result of marking or branding the FreeStyle Products with Nipro trademarks.
If the FreeStyle Products, or any part thereof, are, or in the opinion of Nipro
become, the subject of any claim for infringement of such third party
trademarks, trade names or service marks, or if it is adjudicatively determined
that the FreeStyle Products, or any part thereof, infringe any such third party
trademarks, trade names or service marks, Nipro may substitute a new Nipro
trademark, trade name or service mark to be used to sell or use, as appropriate,
the FreeStyle Products.

<PAGE>

                 11.2.3 The foregoing provisions of this Section 11.2 state the
entire liability and obligations of Nipro, and the exclusive remedy of
TheraSense, with respect to any product liability or other matter covered by
Section 11.2.1 or any alleged infringement of any trademarks, trade names or
service marks by the FreeStyle Products or any part thereof.

          11.3   Indemnification Procedure. A party that intends to claim
                 -------------------------
indemnification (the "Indemnitee") under this Article 11 shall promptly notify
the other party (the "Indemnitor") in writing of any claim, complaint, suit,
proceeding or cause of action with respect to which the Indemnitee intends to
claim such indemnification (for purposes of this Section 11.3, each a "Claim"),
and the Indemnitor shall have sole control of the defense and/or settlement
thereof; provided that the Indemnitee shall have the right to participate, at
its own expense, with counsel of its own choosing in the defense and/or
settlement of such Claim. The indemnification obligations of the parties under
this Article 11 shall not apply to amounts paid in settlement of any Claim if
such settlement is effected without the consent of the Indemnitor, which consent
shall not be withheld or delayed unreasonably. The failure to deliver written
notice to the Indemnitor within a reasonable time after the commencement of any
such Claim shall relieve the Indemnitor of its liability to the Indemnitee under
this Article 11, only to the extent that the failure is prejudicial to its
ability to defend such action, but the omission so to deliver written notice to
the Indemnitor shall not relieve the Indemnitor of any liability to any
Indemnitee otherwise than under this Article 11. The Indemnitee under this
Article 11, and its employees, at the Indemnitor's request and expense, shall
provide full information and reasonable assistance to Indemnitor and its legal
representatives with respect to such Claims covered by this indemnification. It
is understood that only Nipro may claim indemnity under this Article 11 (on its
own behalf or on behalf of an Nipro Indemnitee), and other Nipro Indemnitees may
not directly claim indemnity hereunder. Likewise, it is understood that only
TheraSense may claim indemnity under this Article 11 (on its own behalf or on

                                      -33-
<PAGE>

behalf of a TheraSense Indemnitee), and other TheraSense Indemnitees may not
directly claim indemnity hereunder.

         11.4   Insurance. During the term of this Agreement, each party shall
                ---------
maintain liability insurance policies, including without limitation, product
liability insurance coverage, in commercially adequate amounts. TheraSense's
policy shall name Nipro as an additional insured and contain an endorsement to
provide Nipro with at least thirty (30) days prior written notice of any
cancellation or nonrenewal of such policy. Each party shall furnish to the other
party copies of such policies.

         11.5   LIMITED LIABILITY.
                -----------------

                11.5.1  EXCEPTING THE PROVISIONS OF SECTION 12.6.2, THERASENSE'S
LIABILITY ARISING OUT OF THIS AGREEMENT, THE TERMINATION THEREOF, AND/OR SALE OF
THE FREESTYLE PRODUCTS SHALL BE LIMITED TO THE AMOUNT OF TEN MILLION DOLLARS
(USD $10,000,000).


                11.5.2  IN NO EVENT SHALL THERASENSE OR NIPRO BE LIABLE TO THE
OTHER OR ANY OTHER ENTITY FOR LOST PROFITS, OR ANY OTHER SPECIAL, CONSEQUENTIAL,
OR INCIDENTAL DAMAGES, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY ARISING OUT
OF THIS AGREEMENT, OR ANY TERMINATION THEREOF, WHETHER BASED IN CONTRACT, TORT
(INCLUDING NEGLIGENCE), OR OTHERWISE. THESE LIMITATIONS SHALL APPLY WHETHER OR
NOT THERASENSE OR NIPRO HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND
NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY PROVIDED
HEREIN OR IN THE WARRANTY FOUND IN THE FREESTYLE PRODUCTS.

            12.1.1 Initial Term. The initial term of this Agreement shall
                   ------------
commence on the Effective Date and shall continue in force until five (5) years
from the Effective Date, unless terminated earlier under the provisions of this
Article 12 (the "Initial Term").

fourth (4th) year, either party may notify the other party that it would like to
extend the term by an additional rolling three (3) years (i.e. to add years 6,
7, and 8 to the initial five (5) years). The parties shall then meet and agree
to the Annual Minimum Purchase Obligation of Strips that shall apply for each
additional year. If the parties so agree, this Agreement shall be so extended.

Minimum Purchase Obligation for the extension years prior to

performance of any provision of this Agreement, then the non-defaulting party
may give written notice to the defaulting party that if the default is not cured
within ninety (90) days the Agreement will be terminated. If the non-defaulting
party gives such notice and the default is not cured during the ninety (90) day
period, then the Agreement shall automatically terminate at the end of that
period. In addition, this Agreement shall automatically terminate if Nipro fails
to pay TheraSense in accordance with Sections 3.1 or 3.2 and such failure shall
have continued for thirty (30) days after written notice thereof was provided to

Section 12.4.1.


          12.5   Termination Relating to Sales Outside Territory.

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


                 12.5.1 In addition to any other rights or remedies available to
TheraSense, TheraSense shall have the right to terminate this Agreement upon
thirty (30) days prior written notice to Nipro if Nipro is selling the FreeStyle
Products in commercial quantities, (i) for delivery outside the Territory or
(ii) with knowledge that the FreeStyle Products are being purchased for use or
resale outside the territory, unless Nipro cures such breach within such thirty
(30) day period.


                 12.5.2 In the event either TheraSense or Nipro become aware
that any Nipro Affiliate or Subdistributor (including without limitation
distributors, wholesalers, and retailers) has directly or indirectly resold or
reshipped any of the FreeStyle Products outside the Territory in commercial
quantities, it shall notify the other party in writing. In the event that either
of the parties determine that such Nipro Affiliate or Subdistributor (including
without limitation distributors, wholesalers, and retailers) knew or should have
known that such FreeStyle Products were ultimately being resold or reshipped
outside the Territory, it shall notify the other party and Nipro shall take all
necessary action to stop such activities, including without limitation
terminating the right of such third party to distribute and sell FreeStyle
Products, in accordance with its agreement with the Subdistributor.

                        -------------------
Agreement for any reason shall not release any party hereto from any liability
which, at the time of such termination, has already accrued to the other party
or which is attributable to a period prior to such termination nor preclude
either party from pursuing any rights and remedies it may have hereunder or at
law or in equity with respect to any breach of this Agreement. It is understood
and agreed that monetary damages may not be a sufficient remedy for any breach
of this Agreement and that the non-breaching party may be entitled to injunctive
relief as a remedy for any such breach. Such remedy shall not be deemed to be
the exclusive remedy for any such breach of this Agreement, but shall be in
addition to all other remedies available at law or in equity.

          -----------

          13.2.1 Any Dispute that cannot be settled amicably by agreement of the
parties pursuant to Section 13.1 above shall be finally settled by binding
arbitration in the manner described in this Section 13.2. The ADR shall be
conducted pursuant to then obtaining Rules of Arbitration of the London Court of
International Arbitration, by which each party hereto agrees to be bound.
Notwithstanding those rules, the ADR shall be held in London, England by a
single arbitrator, provided that at the request of any party, the arbitration
shall be conducted by a panel of three (3) arbitrators, with one (1) arbitrator
chosen by each of TheraSense and Nipro and the third appointed by the other two
(2) arbitrators. The parties shall use their best efforts to select the
arbitrator(s) within ninety (90) days of the initiation of ADR. It is understood
and agreed that the filing by a party of an action that is subject to this
Section 13.2, whether in court or in arbitration, shall constitute an
"initiation" of ADR. Each party agrees that any such action filed in court shall
be stayed pending the outcome of the related ADR. The

                                      -41-
<PAGE>

arbitrator(s) selected in accordance with this Section 13.2 are referred to
herein as the "Panel" and shall be comprised of independent experts with
experience in the field of the dispute.

          13.2.2 All ADR proceedings, including without limitation the filing of
any documents, papers, and/or motions relating thereto, shall be made in the
English language. In the event of any dispute concerning the construction or
meaning of such documents, papers and/or motions, reference shall be made only
to such documents, papers and/or motions as written in English and not to any
translation into any other language.

          13.2.3 The decision and/or award rendered by the Panel shall be
written (specifically stating the Panel's findings of facts as well as the
reasons upon which the Panel's decision is based), final and nonappealable
(except for an alleged act of corruption or fraud on the part of the Panel) and
may be entered in any court of competent jurisdiction. The parties agree that,
any provision of applicable law notwithstanding, they will not request, and the
Panel shall have no authority to award, punitive or exemplary damages against
any party. The Panel shall have the authority to grant injunctive relief and
order specific performance. The Panel shall determine what discovery will be
permitted, consistent with the goal of limiting the cost and time which the
parties must expend for discovery; provided the Panel shall permit such
discovery as they deem necessary to permit an equitable resolution of the
dispute. Evidence need not be obtained in the presence of the Panel. At the
arbitration hearing, each party may make written and oral presentations to the
Panel, present testimony and written evidence, and examine witnesses. The costs
of any arbitration, including administrative fees and fees of the Panel, shall
be shared equally by the parties. Each party shall bear the cost of its own
attorneys' fees and expert fees. The parties and the Panel shall use their best
efforts to complete any such arbitration within one (1) year after the
appointment of the Panel, unless a party can demonstrate to the Panel that the
complexity of the issues or other reasons warrant the extension of the time
table. In such case, the Panel may extend such time table as reasonably
required. The Panel shall, in rendering its decision, apply the substantive law
of

                                      -42-
<PAGE>

the State of Delaware, without regard to its conflict of laws provisions, except
that the interpretation of and enforcement of this Section 13.2 shall be
governed by the Rules of Arbitration of the International Chamber of Commerce.
No party shall initiate arbitration hereunder unless it has attempted to resolve
the dispute in accordance with Section 13.1.

          13.2.4 Injunctive Relief. This Section 13.2 shall not be construed to
                 -----------------
prohibit either party from seeking preliminary or permanent injunctive relief,
restraining order or degree of specific performance in any court of competent
jurisdiction to the extent not prohibited by this Agreement. For avoidance of
doubt, any such equitable remedies provided under this Section 13.2 shall be
cumulative and not exclusive and are in addition to any other remedies, which
either party may have under this Agreement or applicable law.

14.  MISCELLANEOUS

     14.1 Governing Law. This Agreement, and any proceeding subject to Article

Affiliates, and (b) to an entity that acquires all or substantially all of the

liable to the other party for damages or losses (except for payment obligations)
on account of failure of performance by the defaulting party if the failure is
occasioned by war, strike, fire, Act of God, earthquake, flood, lockout,

failure to perform is beyond the reasonable control and not caused by the
negligence, intentional conduct or misconduct of the nonperforming party and

     14.7  Advice of Counsel. TheraSense and Nipro have each consulted counsel
           -----------------
of their choice regarding this Agreement, and each acknowledges and agrees that
this Agreement shall not be deemed to have been drafted by one party or another
and will be construed accordingly.

     14.8  Compliance with Laws. Each party shall furnish to the other party any
           --------------------
information requested or required by that party during the term of this
Agreement or any extensions hereof to enable that party to comply with the
requirements of any U.S. or foreign, state and/or government agency.

     14.9  Further Assurances. At any time or from time to time on and after the
           ------------------
date of this Agreement, Nipro shall at the request of TheraSense (i) deliver to
TheraSense such records, data or other documents consistent with the provisions

     14.10 Severability; Waiver. In the event that any provisions of this
           --------------------
Agreement are determined to be invalid or unenforceable by a court of competent
jurisdiction, the remainder of the Agreement shall remain in full force and
effect without said provision. The parties shall in good faith negotiate a
substitute clause for any provision declared invalid or unenforceable, which
shall most nearly approximate the intent of the parties in entering this
Agreement. The failure of a party to enforce any provision of the Agreement
shall not be construed to be a waiver of the right of such party to thereafter
enforce that provision or any other provision or right.

     14.11 Entire Agreement; Modification. This Agreement sets forth the entire
           ----------------
agreement and understanding of the parties with respect to the subject matter
hereof, and supersedes all prior discussions, agreements and writings in
relating thereto. This Agreement may not be altered, amended or modified in any
way except by a writing signed by both parties.
