such litigation.     (b)   In order to discharge the obligations set forth in
Section 5.2(a), each Party agrees to obtain and keep in force during the Term,

6.   TERM; TERMINATION   6.1   Term. The term of this Agreement shall commence
on the Effective Date, and, unless terminated earlier as provided in
Section 6.2, shall continue in full force and effect until expiration of all
claims in all issued patents of the NxStage Dialyzer Manufacturing Patent
Rights, the NxStage Harmony Technology and/or the NxStage Streamline Technology
(the “Term”) and, thereafter, the rights and obligations of the Parties will be
as set forth in Section 6.3.   6.2   Termination for Material Breach or
Insolvency. Either Party may terminate this Agreement in the event the other
Party shall have materially breached or defaulted in the performance of any of
its material obligations hereunder, and such default shall have continued for
[**] after written notice thereof was provided to the breaching Party by the
non-breaching Party. Any termination shall become effective at the end of such
[**] period unless the breaching Party (or any other party on its behalf) has
cured any such breach or default prior to the expiration of the [**] period. If
a petition in bankruptcy or for corporate reorganization or for any similar
relief is filed by or against either Party (and in the case of involuntary
proceedings, is not successfully contested), or a receiver is appointed with
respect to any of the material assets of such Party, or a liquidation proceeding
is commenced by or against such Party (and, in the case of involuntary
proceedings, is not successfully contested) (collectively, hereinafter defined
as “Insolvency”), then the other Party may terminate this Agreement upon thirty
(30) days prior notice; provided that such termination right shall not extend if
the Party is in Chapter 11 rather than Chapter 7 bankruptcy proceedings under
the bankruptcy law of the USA or in similar bankruptcy proceedings of proper law
in any other country.   6.3   Effect of Expiration or Termination.

  (a)   Expiration or termination of this Agreement for any reason shall not
release either Party from any liability or obligation that, at the time of
expiration or such termination, has already accrued to the other Party or that
is attributable to a period prior to expiration or such termination, nor shall
it preclude either Party from pursuing any right and/or remedy that such Party
may have hereunder, at law or in equity, with respect to any breach of this
Agreement.     (b)   Upon any termination of this Agreement, but not expiration
of this Agreement, each Party shall promptly return to the other Party all
Confidential Information received from such other Party except one (1) copy of
which may be retained for archival purposes or as necessary to exercise the
rights and satisfy the obligations of the Party retaining such copy, and for no
other reason.     (c)   Except as provided below, Sections 1, 2.3, 4, 5.2, 5.3,
5.4, 6.3 and 7 shall survive the expiration or the termination of this Agreement
for any reason. Sections 2.1, 2.2, 2.3 and 2.4 shall survive the expiration of
this Agreement, but not the termination of this Agreement pursuant to
Section 6.2.

the termination of this Agreement by Asahi for a reason due to NxStage’s

termination of this Agreement as a consequence of NxStage being in Chapter 7
bankruptcy proceedings under the bankruptcy law of the USA pursuant to
Section 6.2 or while under similar bankruptcy liquidation rather than
reorganization proceedings under the bankruptcy laws of any other country, or
(iii) upon the termination of this Agreement under the direction and consent of
a bankruptcy trustee while NxStage is in Chapter 11 rather than Chapter 7
bankruptcy proceedings under the bankruptcy laws of the USA or while under
similar bankruptcy reorganization rather than liquidation proceedings under the
bankruptcy laws of any other country, or (iv) upon the termination of this
Agreement for any other reason due to NxStage’s Insolvency pursuant to
Section 6.2, Asahi shall retain its rights and licenses granted by NxStage to
Asahi under Sections 2.1 and 2.2 on and after such termination, and Asahi shall
have (i) a right of first refusal against any terms offered and agreed to by any
Third Party to obtain a license under the rights granted to Asahi under
Sections 2.1 and 2.2 to practice such rights in the USA and Canada, and (ii) a
right to practice such first refusal rights until the earlier of [**] after the
initiation of NxStage’s bankruptcy proceedings, or the execution of such right
of first refusal, in exchange for the payment by Asahi to NxStage of [**]
dollars ($[**]). Except as expressly set forth in this Section 6.3, upon such
termination, NxStage’s rights and licenses granted by Asahi to NxStage under
Section 2.2 shall immediately terminate.     (f)   Except as expressly set forth
in this Section 6.3, (i) upon the termination of this Agreement by NxStage for a
reason due to Asahi’s material breach or default hereof pursuant to Section 6.2,

to Section 6.2 or while under similar bankruptcy liquidation rather than
reorganization proceedings under the bankruptcy laws of any other country, or
(iii) upon the termination of this Agreement under the direction and consent of

Agreement for any other reason due to Asahi’s Insolvency pursuant to

7.   MISCELLANEOUS

14

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

 

7.1   Relationship. Each Party is an independent contractor, and neither Party
is the agent, representative or partner of the other Party. Neither Party has
the authority or power to bind or contract in the name of or to create any
liability against the other Party in any way or for any purpose. Each Party
expressly reserves the right to enter other similar agreements with other
Parties on the same or on different terms.   7.2   Assignment and Change of
Control.   7.2.1   In this Section 7.2, the following terms shall have the
following meanings respectively;

  (a)   “Change of Control” means any one of the following events: (i) any
person or two or more persons acting in concert shall have acquired beneficial
ownership, directly or indirectly, of more than fifty percent (50%) of the total
voting power of the stock then outstanding of the Party normally entitled to
vote in elections of directors; (ii) the Party consolidates with or merges into
another entity, or any entity consolidates with or merges into the Party, in
either event pursuant to a transaction in which more than fifty percent (50%) of
the total voting power of the stock outstanding of the surviving entity normally
entitled to vote in elections of directors is not held by the parties holding at
least fifty percent (50%) of such total voting power of the Party preceding such
consolidation or merger; or (iii) the Party conveys, transfers or leases all or
substantially all of its assets to a another entity not an Affiliate of the
Party. Notwithstanding the foregoing, the acquisition/ownership of more than 50%
by any Existing Stockholder or two or more Existing Stockholders (meaning any
stockholder of NxStage Medical as of the Effective Date which beneficially owns,
together with its Affiliates, more than five percent (5%) of the outstanding
capital stock of NxStage Medical as of the Effective Date) will not constitute a
Change of Control. As soon as available after the Effective Date, NxStage shall
provide Asahi with the list of the Existing Stockholders.     (b)   Competitor
of Asahi” means an individual or entity that, as of the date of the Change of
Control, competes with Asahi in the business of the same or competitive products
of Dialyzers.     (c)   “Competitor of NxStage” means an individual or entity
that, as of the date of the Change of Control, competes with NxStage in the
business of the same or competitive products of the NxStage System One.     (d)
  “Permitted Assignee” means (i) Affiliates of the assigning Party, including
Asahi Kasei Corporation and Affiliates of Asahi Kasei Corporation, in case of
Asahi being the assigning Party, and (ii) Third Parties, including Asahi Kasei
Corporation and Affiliates of Asahi Kasei Corporation, in case of Asahi being
the assigning Party, other than a Competitor of the other Party, to whom the
assigning Party transfers all or substantially all of the products, business and
services to which this Agreement relates.

7.2.2   Assignment and Change of Control. This Agreement and the covenants it
contains will be binding and inure to the benefits of the Parties and their
heirs, assigns, successors and legal

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

 

representatives. Except as provided below, (i) no Party may assign this
Agreement, as amended from time to time, other than to a Permitted Assignee, and
(ii) it shall be a condition of any such assignment that the assignee shall, in
writing, assume all obligations of assigning Party under this Agreement. In the
event that an assignee is a Competitor of the other Party to whom the assigning
Party transfers all or substantially all of the products, business and services
to which this Agreement relates, or in the event that a Change of Control event
of the assigning Party arises where the surviving entity is a Competitor of the
other Party, the assigning Party realizes that, if an assignee or surviving
entity is a Competitor, this may significantly affect the business of the other
Party and performance under this Agreement. In the event that an assignee is a
Competitor of either NxStage or Asahi, or a Change of Control event of either
NxStage or Asahi arises where the surviving entity is a Competitor, the Parties
shall meet to discuss what changes, if any, will be required in this Agreement
and the treatment of this Agreement. Despite consultation, if the Parties cannot
find a mutually acceptable solution, notwithstanding anything herein to the
contrary, this Agreement shall nonetheless survive such assignment or Change of
Control; provided that if Asahi is the non-assigning Party, Asahi may elect to
immediately revoke, upon the closing date of such assignment or Change of
Control and upon written notice to the assigning Party all license rights
granted in Improvements under Section 2.2 prior to the date of the closing of
such assignment or Change of Control; and provided further, if Asahi is the
non-assigning Party, the obligations to purchase Simplex Dialyzers from NxStage
under Section 2.1(a)(i) shall terminate upon the closing of such assignment or
Change of Control. License rights and obligations with respect to future
Improvements from and after the closing date of any assignment or Change of
Control of either NxStage or Asahi shall terminate immediately on the date of
such closing.

7.3   Waiver. Failure or neglect by either Party to enforce at any time any of
the provisions hereof shall not be construed nor shall be deemed to be a waiver
of such Party’s rights hereunder nor in any way affect the validity of the whole
or any part of this Agreement nor prejudice such Party’s rights to take
subsequent action.   7.4   Notices. Any notice required or permitted to be given
under this Agreement shall be in writing, shall make specific reference to this
Agreement, and shall be addressed to the appropriate Party at the address
specified below or such other address as may be specified by such Party in
writing in accordance with this Section 7.4, and shall be deemed to have been
given for all purposes (a) when received, if hand-delivered or sent by a
reputable overnight delivery service, (b) on the day of sending by facsimile, if
followed by mailing by first class certified or registered mail, postage
prepaid, return receipt requested, or (c) five (5) days after mailing, if mailed
by first class certified or registered mail, postage prepaid, return receipt
requested.
