sales to Third Parties by such Affiliates or sublicensees.


If a Product is sold as part of a Combination Product (as defined below), Net Sales will be the product of (i) Net Sales of the
Combination Product calculated as above (i.e., calculated as for a non-Combination Product) and (ii) the fraction (A/(A+B)), where:

"A" is the average wholesale acquisition cost of the Product comprising Ronacaleret as the sole therapeutically active
ingredient during the four (4) most recently completed Calendar Quarters during which such non-Combination Products were sold in
such country; and

"B" is the average wholesale acquisition cost in such country of the other therapeutically active ingredients contained in
the Combination Product when sold separately during the four (4) most recently completed Calendar Quarters during which such
products were sold in such country.   

If "A" or "B" cannot be determined by reference to non-Combination Product sales as described above, then
Net Sales for purposes of determining royalty payments will be calculated as above, but the average wholesale acquisition cost in the
above equation shall be determined by GSK prior to the end of the accounting period in question based on an equitable method of
determining same that takes into account, in the applicable country, variations in dosage units and the relative fair market value of each
therapeutically active ingredient in the Combination Product.   

As used in this Section 1.30, "Combination Product" means a Product that contains one or more additional
active ingredients (whether co-formulated or co-packaged) that are neither Ronacaleret nor generic or other non-proprietary
compositions-of-matter.  Pharmaceutical dosage form vehicles, adjuvants and excipients shall be deemed not to be "active
ingredients". 

To the extent the Net Sales definition is used herein with respect to an NPS Compound Product or [*] Product, Net Sales shall have
the meaning set forth above, with all references to "GSK" replaced by "NPS", all references to
"Product" replaced with "NPS Compound Product" or "[*] Product", as applicable.

avoidance of doubt, and by way of example only, if as of the Effective Date, a Patent discloses, but does not claim Ronacaleret
generically or specifically, then such Patent is not a Ronacaleret Patent; provided, that if during the Term of this Agreement, such
Patent issues or is otherwise modified in a manner that results in the claiming of Ronacaleret, then such Patent thereafter shall be
deemed a Ronacaleret Patent for all purposes of this Agreement.

[*]%








                                                14







For illustrative purposes only, if worldwide annual Net Sales of a Product were $[*], the royalties payable with respect to such
annual Net Sales, subject to adjustment as set forth in this Section 5.2 below and Section 6.2, would be [*].  GSK's royalty
obligations to NPS under this Section 5.2(a) in each country shall commence on a country-by-country and Product-by-Product
basis on the date of First Commercial Sale of the Product by GSK, its Affiliates or sublicensees to a Third Party in the relevant country,
and shall expire on a country-by-country and Product-by-Product basis upon the later of the following: (i) the expiration or invalidation of
the last remaining NPS Licensed Ronacaleret Patent in such country which claims the composition of matter or method of using
Ronacaleret or the Product or (ii) the tenth (10th) anniversary of the First Commercial Sale of such Product in such
country by GSK, its Affiliates or sublicensees (the "GSK Royalty Term"). 



	The foregoing provisions of Section 5.2(a) notwithstanding, the
royalties payable with respect to Net Sales of a Product shall be reduced, on a country-by-country basis, to [*] of Net Sales during any
portion of the GSK Royalty Term when (i) all NPS Licensed Ronacaleret Patents in such country that claim the composition of matter or
method of using Ronacaleret or the Product have lapsed, been abandoned or held invalid or unenforceable by a decision of a court or
tribunal of competent jurisdiction from which no appeal is or can be taken; and (b) substantial competition exists in such country.
"Substantial competition", as used in this Section 5.2(b), means a composition of matter that either is the same
chemical entity or has the same mechanism of action as Ronacaleret, and the period of substantial competition shall be applied
retroactively to the date of first commercial sale of such substantial competition in such country, and shall continue only for so long as
such commercialization continues.


	Royalties on Net Sales of the Product for veterinary use, diagnostic use or any other use other than a human ethical
pharmaceutical use shall be calculated separately at [*] of the royalty rates set forth in Sections 5.2(a) or 5.2(b), as
applicable.

5.3   Records.  GSK shall keep, and require its Affiliates and sublicensees to keep, complete and accurate records of all sales
of Products for a period of three (3) years after the relevant payment is owed to NPS pursuant to Section 5.2(a) or
(b).  Upon ninety (90) days' prior written notice, NPS shall have the right to examine such records during regular business
hours using a certified public accountant or like person reasonably acceptable to GSK.  Such examination shall not be performed more
frequently than once in any twelve (12)-month period, and shall be conducted under appropriate confidentiality provisions, for the sole
purpose of verifying the accuracy and completeness of all financial, accounting and numerical information and calculations provided
under this Agreement with respect to royalties paid under Section 5.2 and reports provided under Section 5.4.  The certified public
accountant shall have the right to make copies of relevant portions of GSK's books and records; provided, that any such copies shall be
the Confidential Information of GSK, shall be protected by appropriate confidentiality obligations and shall not be shared with NPS or
any Third Party.  The sole deliverable to NPS shall be a copy of the accounting firm's final report, which also shall be provided to GSK
at the same time.  Such examination is to be made at the expense of NPS, except if the results of the




                                                15







audit reveal an underpayment of royalties under this Agreement of five percent (5%) or more in any calendar year, in which case reasonable audit fees
for such examination shall be paid by GSK.  Any underpayment determined by such audit shall be paid promptly to NPS.


5.4   Reports.  Until the expiration of all applicable Royalty Terms in all countries, GSK shall make
written reports to NPS within [*] days after the end of each calendar quarter, setting forth Net Sales on a country-by-country and Product-by-Product basis and the
royalties due to NPS by GSK during the preceding calendar quarter.  Concurrent with the delivery of each
such report, GSK shall make the royalty payment due to NPS as set forth in
the report.

5.5   Payment Terms.




	All royalties due under this Agreement shall be payable in U.S. dollars. If governmental regulations prevent remittances from a
country to any other country with respect to sales made in that country, the obligation of GSK to pay royalties on sales in that country
shall be suspended until such remittances are possible, and once they are possible, GSK shall pay NPS any back royalties which may
be owed. Alternatively, NPS shall have the right, upon giving written notice to GSK, to receive payment in that country in local
currency.


	With respect to sales of the Product invoiced in Dollars, the Net Sales and the amounts due hereunder
will be expressed in Dollars.  With respect to Net Sales invoiced in a currency other than Dollars, the Net Sales and amounts due
hereunder will be reported in Dollars, calculated using the standard methodologies employed by GSK for consolidation
purposes. As of the Effective Date, the method utilized by GSK's group reporting system uses spot exchange
rates sourced from Reuters/Bloomberg.   

5.6   Taxes.  Any tax paid or required to be withheld by GSK on account of royalties payable to NPS under this Agreement shall
be deducted from the amount of royalties otherwise due.  GSK shall secure and send to NPS written proof of any such taxes withheld
and paid by GSK, its Affiliates or its sublicensees for the benefit of NPS in a form sufficient to satisfy the United States Internal Revenue
Service.

5.6   Royalty Payments by NPS.  As consideration for the assignment of Transferred Compound
Patents related to Existing Compounds to NPS under Section 2.2 of this Agreement, NPS shall pay GSK a royalty rate of [*] on
worldwide annual Net Sales of any pharmaceutical product comprising an Existing Compound, whether or not as the sole active
ingredient and in any dosage form or formulation ("NPS Compound Product").  NPS' royalty obligations under this
Section 5.7 shall commence on a country-by-country and NPS Compound Product-by-NPS Compound Product basis on the
date of First Commercial Sale of the NPS Compound Product by NPS, its Affiliates or sublicensees to a Third Party in the relevant
country, and shall expire on a country-by-country and NPS Compound Product-by-NPS Compound Product basis upon the later of the
following: (i) the expiration or invalidation of the last remaining Transferred Compound Patent in such country which claims the
composition of matter or method of using the Existing Compound or the NPS Compound Product or (ii) the tenth (10th)
anniversary of the First Commercial Sale of such NPS Compound Product in such country by NPS, its Affiliates or sublicensees (the
"NPS Compound Product Royalty Term"). The terms of Sections 5.3, 5.4, 5.5 and 5.6 would apply mutatis
mutandis to the payment of royalties to GSK under this Section 5.7.




                                                16






6.   COMPULSORY LICENSES AND THIRD PARTY LICENSES.

6.1   Compulsory Licenses.  In the event that a governmental agency in any country or territory grants or compels NPS to grant a
license to the NPS Licensed Ronacaleret Patents to any Third Party to make, have made, use or sell Ronacaleret, GSK shall have the
benefit in such country or territory of the terms granted to such Third Party to the extent that such terms are more favorable to the Third
Party than those of this Agreement.

6.1   Third Party Licenses.   If, during the Term, GSK's
Average Gross Margin on Net Sales of the Product during a particular calendar year falls below [*] in a particular country as a result of
royalty payments made by GSK to Third Parties on such Net Sales for license rights to Patents or Data owned or Controlled by such
Third Parties that are necessary for the manufacture, use, offer for sale, sale or importation of such Product in such country, then
GSK's royalty obligations under Section 5.2(a) shall be reduced by the amount required to raise GSK's Average Gross Margin
to [*]; provided that the reduction shall not be greater than (x) [*] of the total royalty payable by GSK to such Third Parties or (y) [*] of the
royalty payable by GSK to NPS on such Net Sales in such country under Section 5.2(a).   "Average
Gross Margin" means Net Sales during a calendar year minus Cost of Goods Sold attributable to the Product sold, minus all
royalties payable by GSK to NPS and all Third Parties on such Net Sales.

diagnosis or treatment of hypoparathyroidism if NPS, its




                                                17








Affiliates or sublicensees launches a pharmaceutical product containing
NPSP558 on or before June 1, 2017.  The foregoing covenant shall not prevent, limit or restrict GSK or any of its Affiliates or licensees
from making, having made, using, selling or otherwise developing or commercializing any compound or product other than Ronacaleret
for the prevention, diagnosis or treatment of hypoparathyroidism.  In addition, nothing in the foregoing covenant shall prohibit GSK from

and agree that the foregoing covenant shall not prevent, limit or restrict NPS, its Affiliates or any of its licensees from making, having
made, using, selling or otherwise Developing or commercializing any compound or product other than the Transferred Compounds and
Existing Compounds in any field of use or indication, including, without limitation, ADHH.


	NPS shall not, and shall cause its Affiliates to not, directly or indirectly through any Third Party, make, have made, use, sell or

8.   TERM AND TERMINATION.


8.1   Term.  This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 8,
shall remain in effect until it expires (the "Term") as follows:




	On a Product-by-Product and country-by-country basis, this Agreement shall expire on the date of the expiration of all applicable
GSK Royalty Terms with respect to such Product in such country; and




                                                18









	This Agreement shall expire in its entirety upon the expiration of all applicable GSK Royalty Terms under this Agreement with
respect to all Products in all countries in the Territory.


	Upon expiration of the Term, GSK shall have a fully paid-up, non-exclusive, perpetual license to
use the applicable NPS Licensed Ronacaleret Patents and Ronacaleret Know-How to make, have made, use, sell, offer for sale and
import Ronacaleret and Products in the GSK Field.  To the extent that any [*] Product Royalty Term or NPS Compound Product Royalty
Term survives expiration of the Term, NPS shall be obligated to continue to pay royalties to GSK for the remainder of the applicable [*]
Product Royalty Term or NPS Compound Product Royalty Term.           

8.2   Termination for Default.  Either Party (the "Non-
Breaching Party") may, without prejudice to any other remedies available to it under Applicable Law or in equity, terminate
this Agreement if the other Party (the "Breaching Party") shall have materially breached or defaulted in the
performance of its obligations hereunder, and such default shall have continued for sixty (60) days after written notice thereof was
provided to the Breaching Party by the Non-Breaching Party, such notice describing the alleged breach.  Any such termination of this
Agreement shall become effective at the end of such sixty (60) day cure period, unless:




	the Breaching Party has cured such breach or default prior to the expiration of such cure period; or


	such breach is not susceptible to cure within such cure period even with the use of Commercially Reasonable Efforts, in which
event the Non-Breaching Party's right to termination shall be suspended only if and for so long as (i) the Breaching Party has provided
to the Non-Breaching Party a written plan that is reasonably calculated to effect a cure, (ii) such plan is reasonably acceptable to the
Non-Breaching Party, and (iii) the Breaching Party commits to and does carry out such plan.  Where the
Non-breaching Party has accepted any such plan in accordance with the
preceding sentence, the Non-breaching Party may terminate this Agreement immediately upon written notice to the Breaching Party if the Breaching Party subsequently fails
to carry out such plan.  

8.3   Country Specific Termination. GSK may
terminate this Agreement with respect to any country or all countries by giving NPS at least thirty (30) days written notice thereof (the
"Country Termination Notice") based on a reasonable determination by GSK, using the same standards GSK
would use in assessing whether or not to continue Development or commercialization of a product solely and exclusively owned by it,
that the patent, medical/scientific, technical, regulatory or commercial profile of Ronacaleret does not justify continued Development or
commercialization of Ronacaleret in such country or countries; provided, that NPS may delay the effective date of such termination for
up to six (6) months (the "Delay Period") in any country in which GSK, its Affiliates or sublicensees are
commercializing Ronacaleret on the date on which GSK provides the Country Termination Notice if, within sixty (60) days of NPS'
receipt of the Country Termination Notice, NPS (a) gives written notice to GSK that NPS intends to continue the commercialization of
Ronacaleret on its own or through Third Party sublicensees, in accordance with a reasonable marketing plan provided to GSK with




                                                19







such notice and (b) during the Delay Period, NPS uses Commercially Reasonable Efforts to implement such plan.  If NPS uses
Commercially Reasonable Efforts to implement such marketing plan during the Delay Period, then GSK hereby grants to NPS an
exclusive license to Ronacaleret Patents and Ronacaleret Know-How owned or Controlled by GSK to make, have made, use, offer to
sell, sell and import Ronacaleret in the GSK Field in such terminated countries as described in this Section 8.3.

GSK in such country under Section 3.1 with full reversion to NPS of all NPS' interest and rights in NPS Licensed Ronacaleret
Patents and Ronacaleret Know-How in such country.  Termination by GSK of this Agreement with respect to any countries or all
countries under this Section 8.3 shall not affect the license granted to NPS by GSK in accordance with Section 3.2 which shall remain
in effect after any such termination, subject to all applicable terms and conditions of this Agreement.


8.4   Termination for Bankruptcy.




	Either Party may terminate this Agreement if, at any time, the other Party shall file in any court
or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for
an arrangement or for the appointment of a receiver or trustee of the Party or of its assets, or if such Party proposes a written
agreement of composition or extension of its debts, or is served with an involuntary petition against it, filed in any insolvency
proceeding, and such petition is not dismissed within sixty (60) days after the filing thereof, or if such Party shall propose or be a party
to any dissolution or liquidation, or if such Party shall make an assignment for the benefit of creditors.


	Notwithstanding the bankruptcy of NPS, or the impairment of performance by NPS of its obligations under this Agreement as a
result of bankruptcy or insolvency of NPS, GSK shall be entitled to retain the licenses granted herein, subject to NPS' rights to
terminate this Agreement for reasons other than bankruptcy or insolvency as expressly provided in this Agreement, and subject to
performance by GSK of its preexisting obligations under this Agreement.  Notwithstanding the bankruptcy of GSK, or the impairment of
performance by GSK of its obligations under this Agreement as a result of bankruptcy or insolvency of GSK, NPS shall be entitled to
retain the licenses granted herein, subject to GSK's rights to terminate this Agreement for reasons other than bankruptcy or insolvency
as expressly provided in this Agreement, and subject to performance by NPS of its preexisting obligations under this Agreement.

as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S.
Bankruptcy Code, or any other provisions of Applicable Law outside the United States that provide similar protection for intellectual
property rights, subject to performance by the licensee of its preexisting obligations under this Agreement. The Parties further agree
that, in the event that any proceeding shall be instituted by or against licensor under the U.S. Bankruptcy Code seeking to adjudicate it
bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition of it or its





                                                20








debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking an entry of an order for
relief or the appointment of a receiver, trustee or other similar official for it or any substantial part of its property or it shall take any
action to authorize any of the foregoing actions (each a "Proceeding"), the licensee shall have the right to retain
and enforce its rights under this Agreement, including but not limited to the following rights:

all embodiments of the foregoing, and the same, if not already in licensee's possession.  Such materials shall be promptly delivered to
licensee (1) upon any such commencement of a Proceeding upon written request therefor by licensee, unless licensor elects to

upon ninety (90) days prior written notice to GSK if Ronacaleret is not in Development or under commercialization by GSK, its Affiliates
or sublicensees for a period of [*]. Upon receipt of such written notice, GSK will have forty-five (45) days from the receipt of such notice
to verify to NPS that it either (i) is [*] Ronacaleret, (ii) has Ronacaleret [*] or (iii) intends to have Ronacaleret enter [*].  If GSK
reasonably demonstrates such intent to the reasonable satisfaction of NPS, there shall be no such termination.

sale of which would, but for the termination, be subject to royalty, and GSK, its Affiliates, sublicensees and distributors shall thereupon
be permitted to sell that amount of Ronacaleret provided that GSK pays the royalty thereon at the time herein provided for.

9.4   Effect of Termination for Bankruptcy.




	If, as a result of the happening of any event described in Section 8.4(a), any tangible or intangible asset owned by
NPS relating to Ronacaleret (e.g., intellectual property) is offered for sale or license, in addition to other remedies in law or
equity which may be available to GSK, GSK shall have a right of first refusal with respect to the asset; provided, that to the extent the
asset also relates to subject matter other than Ronacaleret, GSK's right of first refusal shall extend only to so much of the asset as

10.   CONFIDENTIALITY.


10.1   Definition of Confidential Information.  "Confidential Information" means any and all proprietary
information furnished or made available to one Party (the "Receiving Party") by the other Party (the
"Disclosing Party") relating to the Disclosing Party's current or future business, or any other proprietary information
of the Disclosing Party whether in written, oral, electronic or other form.  For purposes of clarification, all data, information and know-how




                                                23







contained in any Transferred Assets shall be deemed to be Confidential Information of NPS, and all Confidential Information
exchanged during the term of the Original Agreement shall remain subject to the terms and conditions of this Article 10.  In addition, the
terms and conditions of this Agreement are hereby deemed to be Confidential Information of both Parties.

10.2   Obligations of Nonuse and Nondisclosure.  The Receiving
Party (a) shall hold the Disclosing Party's Confidential Information in strict confidence, (b) shall not disclose such Confidential
Information to any Third Party and shall employ reasonable practices and procedures necessary to prevent such disclosure, which
steps shall include at least those taken by the Receiving Party to protect its own confidential information of like kind, and (c) shall not
use such Confidential Information unless the Disclosing Party has agreed otherwise in writing. Notwithstanding the foregoing, the
Receiving Party may disclose the Disclosing Party's Confidential Information to the Receiving Party's Affiliates, employees, licensees,
agents, advisors, financing sources, potential acquirors, sublicensees or distributors (collectively "Responsible
Persons") who have a bona fide need to know, but only to the extent reasonably necessary to perform its obligations
under this Agreement or to perform due diligence on the Receiving Party.  The Receiving Party (i) will inform all Responsible Persons in
writing that such Confidential Information is confidential and is not to be disclosed to Third Parties, (ii) will obligate all Responsible
Persons in writing to abide by the nondisclosure and nonuse obligations of this Agreement, and (iii) will be responsible for any
noncompliance by Responsible Persons. Notwithstanding the foregoing, but subject to Section 10.3, these
obligations of nonuse and nondisclosure shall not be breached by disclosures that are required for purposes of investigating,
developing, manufacturing or marketing an Existing Compound, Transferred Compound or Ronacaleret, or for securing essential or
desirable authorizations, privileges or rights from governmental agencies with respect to Existing Compounds, Transferred Compounds
or Ronacaleret, or that are necessary to file or prosecute patent applications concerning Existing Compounds, Transferred Compounds
or Ronacaleret, or to carry out litigation concerning Existing Compounds, Transferred Compounds or Ronacaleret.  Further, nothing in
this Section 10.2 shall be construed as preventing or in any way inhibiting GSK or NPS from complying with statutory and
regulatory requirements governing the Development, manufacture, use and sale or other distribution of an Existing Compound,
Transferred Compound or Ronacaleret in any manner which it reasonably deems appropriate.

10.3   Exclusions from Confidential Information.  The obligations of nondisclosure and nonuse in Section 10.2 shall
not apply to any part of the Confidential Information which the Receiving Party can show by clear and convincing evidence using written
documents (a) was already known to the Receiving Party before receiving such information from the Disclosing Party, (b) is or
becomes known to the public or generally available to the public through no fault of the Receiving Party, (c) is rightfully furnished to the
Receiving Party by a Third Party who has not received such Confidential Information, directly or indirectly, from the Disclosing Party or
any other party under an obligation of nondisclosure or nonuse, or (d) is independently developed by or for the Receiving Party without
use of Confidential Information received from the Disclosing Party.


10.4   Judicial Order.  The obligation of nondisclosure in this Agreement shall not be breached by disclosure required in a judicial
proceeding or governmental investigation, provided




                                                24







the Receiving Party gives the Disclosing Party prior written notice of such
requirement and affords the Disclosing Party an opportunity to oppose such disclosure or seek a protective order.

10.5   Public Announcement.  No public announcement or other disclosure to Third Parties concerning the existence of or terms
of this Agreement shall be made, either directly or indirectly, by any Party to this Agreement, except as may be legally required or as
may be required for recording purposes, without first obtaining the approval of the other Party and agreement upon the nature and text
of such announcement or disclosure. The Party desiring to make any such public announcement or other disclosure shall inform the
other Party of the proposed announcement or disclosure in reasonably sufficient time prior to public release, and shall provide the other
Party with a written copy thereof, in order to allow such other Party to comment upon such announcement or disclosure. Each Party
agrees that it shall cooperate fully with the other with respect to all disclosures regarding this Agreement to the Securities Exchange
Commission and any other governmental or regulatory agencies, including requests for confidential treatment of proprietary information
of either Party included in any such disclosure.

10.6   Clinical Trial
Register.  GSK shall have the right to publish the results or summaries of results of all clinical
trials (including meta-analysis or observational studies) conducted by or on behalf of GSK with respect to
Ronacaleret or Products in any clinical trial register maintained by GSK or its Affiliates and the protocols of clinical trials relating to Ronacaleret or Products on www.ClinicalTrials.gov
(and/or in each case publish the results, summaries and/or protocols of clinical trials on such other websites and/or repositories as
required by Applicable Laws or GSK's or its Affiliates' policies).  Each such
publication made in accordance with this Section 10.6 shall not be a breach of the confidentiality obligations
provided in this Article 10.  It is understood and agreed that NPS shall not have the right to
publish any information regarding the Development of Ronacaleret, whether such Development was conducted during the term of the
Original Agreement or under this Agreement, without the prior written consent of GSK, which consent GSK may withhold in its
discretion; provided, that if GSK consents to such publication, then GSK shall have the right to review, comment on and approve such
publication which shall be made in accordance with all relevant GSK policies and procedures, including all policies regarding scientific
engagement.

10.7   Return of Confidential Information.  Except as otherwise
provided in Article 9 of this Agreement, upon termination of this Agreement, each Party hereto and its Affiliates shall use Commercially
Reasonable Efforts to return all Confidential Information of the other Party in its possession to the other Party; provided, that each Party
may retain: (a) a single archival copy of the Confidential Information of the other Party; (b) any portion of the Confidential Information of
the other Party which is contained in laboratory notebooks or other electronic systems, the deletion from which would not be
practicable; in either case, solely for the purpose of determining the extent of disclosure of Confidential Information hereunder,
assuring compliance with the surviving provisions of this Agreement, relevant document retention policies of the Party and Applicable
Laws.

unenforceable, and NPS shall thereafter have the right, at its sole expense, to prepare, file, prosecute and maintain such Patents in
such country.

including settlement thereof; provided, that if such infringement relates to a Ronacaleret Patent (including NPS Licensed Ronacaleret
Patents) that, at the time of such infringement action, generically or specifically claims [*], then NPS shall control such action, at its sole
expense, subject to Section 11.4.   NPS shall have the sole right but not the obligation to bring, at its own expense, an infringement
action or file any other appropriate action or claim directly related to infringement of the `003 Patent and/or the `684 Patent, wherein

reasonable assistance to the other Party as required (i) to facilitate filing of all patent applications covering inventions referred to in
Section 11.1 and shall execute all documents deemed necessary or desirable therefor, and (ii) in connection with any litigation
regarding Patents as described in Sections 11.2(c) and 11.2(d).

11.4   Consultation; Cooperation.  With respect to any Transferred Compound Patents that disclose or describe Ronacaleret,
and any Ronacaleret Patents that disclose, describe or claim Transferred Compounds, respectively, the Parties will use reasonable
efforts to keep each other informed of issues in the prosecution, enforcement or defense of Transferred
Compound Patents that are likely to have a material effect on Ronacaleret, and Ronacaleret Patents that are likely to have a material
effect on Transferred Compounds, respectively. Each Party will allow the other Party the right to review and comment on any such
material issues, and each Party will consider the input of the other in good faith.  The Parties shall be responsible for formulating a
strategy for the protection of Transferred Compound Patents that disclose or describe Ronacaleret, and Ronacaleret Patents that
disclose, describe or claim Transferred Compounds to ensure consistency between the Parties with respect to the prosecution,
enforcement and defense of all such Patents.  The foregoing principles shall also apply to the extent that NPS is controlling any

to perform, unless conclusive evidence to the contrary is provided, the Party so affected shall, upon giving written notice to the other
Party, be excused from such performance to the extent of such prevention, restriction, interference or delay, provided that the affected
Party shall use its reasonable best efforts to avoid or remove such causes of non-performance and shall continue performance with the
utmost dispatch whenever such causes are removed. When such circumstances arise, the parties shall discuss what, if any,
modification of the terms of this Agreement may be required in order to arrive at an equitable solution.

14.2   Governing Law.  This Agreement shall be deemed to have been made in the State of Delaware and its form, execution,

referred to as "Dispute") shall be attempted to be settled by the parties, in good faith, by submitting each such
Dispute to appropriate senior management representatives of each Party in an effort to affect a mutually acceptable resolution thereof.
In the event no mutually acceptable resolution is achieved, then each Party shall be




                                                32







entitled to seek relief for such Dispute by using any
appropriate mechanism which may be available, such as, but not limited to, judicial relief.

14.4   Severability.  In the event any portion of this Agreement shall be held illegal, void or
ineffective, the remaining portions shall remain in full force and effect.  If any of the terms or provisions of this Agreement are in conflict
with any applicable statute or rule of law, then such terms or provisions shall be deemed inoperative to the extent that they may conflict
therewith and shall be deemed to be modified to conform with such statute or rule of law.  In the event that the terms and conditions of
this Agreement are materially altered as a result of this Section 14.4, the Parties will renegotiate such terms and conditions of
this Agreement to resolve any inequities.

solely responsible for all tangible assets included in the Transferred Assets against any such loss.



	No Transfer of Liabilities.  As between NPS and GSK, GSK will be solely responsible for and pay, perform and/or
otherwise discharge when due those Liabilities (including any Liabilities arising in respect of taxes) arising out of or in connection with or

enlarge or in any way affect the provisions, including warranties, covenants, agreements, conditions, representations or, in general any
of rights and remedies, and any of the obligations of GSK or NPS set forth in the License Agreement. This Assignment Agreement is
subject to and governed entirely in accordance with the terms and conditions of the License Agreement.
