LICENSEE shall thereafter issue firm purchase orders to Nastech for Product on a
rolling [***] basis -- each purchase order shall be accompanied by a forecast of
LICENSEE's quantity requirements for Product for the subsequent [***] months
following the period for which the purchase order is made, provided that no
forecasts or orders need be given

for any period after the term of this Agreement. If following Commercial Launch
a required forecast and firm purchase order for [***] is not submitted for the
Product within [***] business after the beginning of [***], the last submitted
[***] forecast shall become the new forecast and the forecast for the
immediately following [***] shall become a binding purchase order. LICENSEE's
forecasts and orders shall reflect its good faith expectations of customer
demand and LICENSEE shall act in a commercially reasonable manner to schedule
orders to avoid creating production capacity problems for Nastech. LICENSEE's
forecasts shall be non-binding except for the binding purchase orders based on
forecasts of the immediately following [***] and that, to the extent that
Nastech is required to place orders for the long lead time items (items with a
lead time of greater than [***] days) used in the Manufacture of Product that
are specified in Schedule 8.3 hereto, based on LICENSEE's forecasts; and Nastech
is actually unable to use such items because LICENSEE orders less Product than
most recently forecast LICENSEE shall reimburse Nastech for its out-of-pocket
costs for such items. Schedule 8.3 shall be revised by the Parties in good faith
to the extent that additional items become only available on a long lead time
basis, and to the extent that item no longer requires long lead times.

(e) Orders for Product shall be made by LICENSEE pursuant to written
binding purchase orders that specify the quantities ordered and the delivery
date. The quantity of Product ordered shall be no less than [***] percent
([***]%) and no more than [***] percent ([***]%) of the most recently provided
forecast for such period. Once received by Nastech, such purchase orders may not
be cancelled or modified by LICENSEE without Nastech's prior written consent,
which shall not be unreasonably withheld.

8.4. No Additional Terms. All contrary, inconsistent or additional
provisions, terms and conditions of any forecast, purchase order, sales or order
acknowledgment, invoice or other standard business form of either Party (a
"Form") are hereby expressly rejected and superseded by this Agreement and shall
be disregarded and have no force and effect. If a Form purports to be
conditioned in any manner on agreement to and/or acceptance of any provisions,
terms and conditions other than those set forth herein, then such condition is
hereby waived.

8.5. Purchase Quantities. All firm orders for Product shall be made in lot
sizes or whole multiples thereof as provided in the Specifications for the
Product. Each such firm order shall specify the quantity of units of the Product
being ordered. Delivery of at least [***] percent ([***]%) and no more than
[***] ([***]%) of the quantities specified on the firm order shall be deemed
satisfactory fulfillment of such order.

8.6. Price. The price to be paid by LICENSEE to Nastech for the Product
ordered by LICENSEE from Nastech hereunder during the term of this Agreement,
including Samples, shall be [***]. Nastech may increase the [***] only in
accordance with Appendix C. Changes to the pricing schedule stated in Schedule
C1 shall reflect actual pricing increases incurred by Nastech. To the extent
such price increases are in excess of [***], such price increases shall only be
effected with the consent of the Parties, provided that if such increases are
reasonably evidenced by Nastech then LICENSEE shall not unreasonably withhold or
delay its consent.

8.7. Quality Agreement. The Quality Agreement further details the quality
assurance obligations and responsibilities of the Parties with respect to the
Product. Notwithstanding

anything to the contrary in this Agreement or in any other document or
agreement, in the event of a conflict between this Agreement and the Quality
Agreement, this Agreement shall govern and control.

8.8. Recordkeeping; LICENSEE Audit. Nastech shall keep accurate records in
sufficient detail to enable LICENSEE or its representative to determine
Nastech's Manufacturing Cost applicable to the Product. LICENSEE shall have the
option, once each Calendar Year, to designate an independent public accountant
mutually agreed to by Nastech and LICENSEE (such agreement not to be
unreasonably delayed or withheld) to conduct a confidential review of records
sufficient to verify Nastech's Manufacturing Cost applicable to the Product sold
to LICENSEE by Nastech hereunder during the preceding [***] and the Product
prices invoiced by Nastech during such [***] period. Such reviews shall be
performed in a confidential manner upon not less than two (2) weeks' prior
written notice and shall be conducted during normal business hours and without
undue interference with Nastech's operations. Such accountant shall not in any
way be compensated (in whole or in part) contingent on the outcome of the audit.
Promptly following the report of the independent accountant, the Parties shall
resolve any over-charges or under-charges in good faith. Nastech shall reimburse
LICENSEE forthwith the amount of any over-charges actually paid by LICENSEE plus
interest thereon for the period from the date originally paid based on the
representative prime rate published by The Wall Street Journal as of the date of
the notice of such over-charge. If the audit discloses over-charges to LICENSEE
in excess of five percent (5%) of the aggregate charges as correctly calculated
for any Calendar Year, Nastech shall also reimburse LICENSEE's reasonable costs
of conducting the review. If the audit discloses undercharges to LICENSEE, such
undercharges shall be billed to, and payable by, LICENSEE.

8.9. Delivery and Payment Terms. The terms of delivery for the Product
shall be F.C.A. (Incoterms 2000) Nastech's Bothell, Washington or Nastech's
Hauppauge, New York or Nastech's designee's (to the extent authorized under
Section 16.3) manufacturing plant. All Product shipped shall be in finished
dosage form, packaged and labeled for commercial sale and shall be properly
prepared for safe and lawful bulk shipment by Nastech or such Nastech designee
according to the Specifications, shall be shipped to LICENSEE's distribution
center or other location designated by LICENSEE, via the common carrier
designated by LICENSEE, and shall be accompanied by appropriate transportation
and other agreed upon documentation. Said common carrier shall execute all
shipments under controlled storage conditions and with proper documentation of
such control, as required by the Quality Agreement, the FDA and other Applicable
Law, and as set forth in the Specifications. Payment for all Product shipped by
Nastech to LICENSEE shall be net thirty (30) days following the date of actual
shipment.

9. Compliance; Adverse Drug Events, Governmental Inquiries, Reporting.

9.1. Regulatory Notice. Each Party shall give to the other Party prompt
written notice of any failure, or allegation of failure by any Regulatory
Authority or other Person, of the notifying Party to comply with the provisions
of Applicable Laws in any manner which affects or could affect the manufacture
of the Product or the performance by the notifying Party of its obligations
under this Agreement. Each Party shall give the other reasonable notice of any
FDA or other Regulatory Authority inspection and a representative of the noticed
party shall have the

right to observe said inspection during its conduct, to the extent permitted by
the FDA or such other Regulatory Authority. Each Party shall also provide to the
other Party, and cause each supplier or packager of Product materials or
components to provide to the other Party, by telefax within [***] of the receipt
thereof, a copy of all FDA 483 observations and all FDA notices and
correspondence relating to the Product or the facilities in which the Product or
any materials or components thereof are manufactured, processed, packaged or
stored, and to promptly provide the other Party with a draft of any response
thereto proposed to be made by the notifying Party and to incorporate any
reasonable suggestions made by the other Party with respect thereto.

9.2. Regulatory Matters. Subject to Nastech's obligations under Section 4
above, the Parties will jointly control all regulatory matters regarding the
marketing, import, export, use, offer for sale or sale of the Product hereunder
as well as matters related to the manufacture of the Product when Nastech is the
manufacturer of the Product. As between the parties, LICENSEE will have the sole
responsibility to respond to product and medical complaints concerning the
Product hereunder.

9.3. Efficacy and Safety Information. Nastech shall furnish LICENSEE with
such efficacy and safety information as is required by law and otherwise is in
the possession or control of Nastech to assist LICENSEE in the marketing,
promotion, sale and distribution of the Product.

9.4. Adverse Drug Experiences. LICENSEE shall notify Nastech of any
Adverse Drug Experience of which the LICENSEE becomes aware within [***] after
first becoming aware thereof. As required under 21 CFR 314.98 and 314.80,
Nastech is required to submit postmarketing safety reports to the Agency for
both serious and nonserious adverse experiences. In order for Nastech to meet
this reporting obligation, and in compliance with 21CFR314.80(C)(1)(iii) and
FDA's "Guidance for Industry - Postmarketing Safety Reporting for Human Drug and
Biological Products Including Vaccines", LICENSEE shall provide supporting
information as required under these regulations.

All reports under this Section 9.4 shall be made by telephone or telefax
as follows:

Nastech Pharmaceutical Company Inc.
Executive Vice President of Clinical Research
& Medical Affairs

and contemporaneously confirmed in writing.

9.5. Product Recall. Each Party shall promptly notify the other Party in
writing of any order, request or directive of a court or other governmental
authority or other decision to recall or withdraw any of the Product in any
jurisdiction. In the event that either Party believes it may be necessary to
conduct a recall, field correction, market withdrawal, stock recovery, or other
similar action with respect to any Product which was sold under this Agreement
(a "Recall"),

they shall promptly consult with each other in good faith as to how best to
proceed, it being understood and agreed that the final decision as to any Recall
of any Product shall be made by LICENSEE; provided however, that neither Party
shall be prohibited hereunder from taking any action that it is required to take
by Applicable Law. Each of Nastech and LICENSEE shall make a permanent, complete
and accurate record of all costs incurred by it in connection with any Product
recall, a copy of which shall be delivered to the other party upon its request
as soon after the completion of such recall or seizure as practically may be
done. If the cause of, or reason for, said recall is attributable to the
negligence or breach of this Agreement by LICENSEE or is associated with any
general recall of other products of LICENSEE, the total cost of the recall to
the parties shall be borne by LICENSEE. If the cause of, or reason for, said
recall or seizure is attributable to the negligence or breach of this Agreement
by Nastech or is associated with any general recall of other products of
Nastech, then Nastech shall reimburse LICENSEE for all reasonable out-of-pocket
costs incurred by it in effecting such recall or seizure. If the reason for the
Recall is not attributable to Nastech or Licensee according to the foregoing and
is due to reasons beyond the reasonable control of the Parties, then the Parties
shall equally share the cost of such Recall and shall promptly reimburse each
other as applicable. If Nastech and LICENSEE cannot agree which party is at
fault or whether the recall was reasonably beyond the control of the parties,
then an independent technical expert, acceptable to both, will be designated to
make the determination. The so designated technical expert shall not be an
employee, consultant, officer, director or shareholder of or otherwise
associated with any party or an Affiliate of any party. The technical expert's
determination shall be, in the absence of fraud or manifest error, binding and
conclusive upon the parties. In the case of fraud or manifest error, the dispute
resolution mechanism of Article XVII shall apply.

9.6. Medical Inquiries. LICENSEE shall handle all medical inquiries
concerning the Product. If Nastech receives any such medical inquiries, it shall
refer such inquiries in writing to:

9.7. Inspection. For the purposes of LICENSEE's compliance with Applicable
Laws governing its activities under this Agreement, Nastech shall, upon
reasonable (but not fewer than fifteen (15) days') prior written notice by
LICENSEE to Nastech, allow or provide for LICENSEE and its representatives to
inspect the respective facilities of Nastech and its designees approved by
LICENSEE, respectively, used for the manufacture of the Product, not more than
once annually (in the absence of the occurrence of extraordinary events
requiring any additional inspection, such as failure to timely supply or the
receipt of any 483), to confirm that

the facilities and the equipment, personnel and operating and testing procedures
used by such parties in the manufacture, testing, storage and distribution of
the Product hereunder are in compliance with cGMPs. Within [***] after its
receipt of any report and observations of LICENSEE resulting from any such
inspection, Nastech shall provide LICENSEE with a formal written response
(including expeditious time lines to complete any necessary corrective action).

LICENSEE will respond to Nastech with any questions Nastech has as a result of
the response of Nastech within [***] after LICENSEE's receipt of notice thereof.
Nastech shall expeditiously pursue any indicated corrective actions to
completion and resolve any related issues, and each communication between the
Parties for this purpose shall occur not later than [***] following a Party's
receipt of the most recent communication from the other Party with respect
thereto until all such actions and issues are completed and resolved. In the
event that a dispute arises between Nastech and LICENSEE regarding the necessity
or fulfillment, of such corrective actions or otherwise arising under this
Article 9, the senior management of the Parties shall in good faith promptly
attempt to resolve disputed issues. If the parties cannot reach agreement, the
matter shall be resolved in accordance with Article 17 hereof.

9.8. Regulatory Materials. Each Party either currently has or will at all
relevant times during the term of this Agreement have sufficient access and
rights to all regulatory materials filed by it with Regulatory Authorities
relevant to the Product and the supporting raw data therefor, as required to
support the development and marketing approval of the Product and its
obligations under this Agreement. Each Party shall, as requested by the other,
at all relevant times during the term of this Agreement disclose such regulatory
materials and data to the other and shall authorize the other to include such
regulatory materials and data in any applications for Regulatory Approval
hereunder. Notwithstanding the foregoing, neither Party makes any
representation, warranty or covenant, and shall have no liability or
responsibility under this Section 9.8 with respect to, any regulatory materials
or other Know-How provided or made available to it by the other, whether or not
filed, disclosed, or relied upon by such Party. Each Party represents, warrants,
and covenants to the other that such other Party currently has, and will at all
relevant times during the term of this Agreement have, access and rights to all
such regulatory materials, as are or become within the possession or control of
such representing Party, sufficient for the other to file the same and the
supporting raw data therefor, and analyses thereof, relevant to the Product and
useful to support the development and Regulatory Approval of the Product, with
Regulatory Authorities and that each Party has and will at all relevant times
during the term of this Agreement have the right to disclose such regulatory
materials and data to the Regulatory Authorities, its Affiliates, and
sublicensees and to include such regulatory materials and data in any
applications for Regulatory Approval of the Product in the Territory, and each
Party shall mutually cooperate with respect thereto.

initiate and use diligent efforts to prosecute such actions as are necessary to
cause the termination of each infringement of the Patent Rights by an Intranasal
Calcitonin Product ("Nastech Patent Infringement") as soon as possible, at
Nastech's sole expense, which shall be recouped in full [***]. Nastech will keep
LICENSEE fully informed of the actions taken and the progress of such actions.
LICENSEE will provide Nastech with reasonable assistance and cooperation in such
actions, at LICENSEE's sole expense which shall be recouped in full [***],
including joining any lawsuits and similar proceedings as a party plaintiff and
taking such other actions as are required to bring or maintain such lawsuits and
proceedings. LICENSEE will have the right to otherwise participate in all such
actions, lawsuits and proceedings with counsel of its own choosing, at
LICENSEE's sole expense which shall be recouped in full [***].

With regard to those patents set forth in Appendix A or issuing from
applications set forth in Appendix A, issuing LICENSEE shall have the first
right, but not the obligation, to assert such patents against potential third
party infringers. LICENSEE shall have sole control of such proceeding which
shall be conducted at LICENSEE's sole cost and expense, which shall be recouped
in full [***]. LICENSEE will keep Nastech fully informed of the actions taken
and the progress of such actions. Nastech will provide LICENSEE with reasonable
assistance and cooperation in such actions, at Nastech's sole expense which
shall be recouped in full [***], including joining any lawsuits and similar

in full [***].

(iii) In the event that Nastech has not within [***] after
LICENSEE's request terminated the Nastech Patent Infringement, or instituted a
lawsuit or similar proceeding that asserts infringement of the Patent Rights in
an effort to do so, or if at any time thereafter such lawsuit is not diligently
pursued to LICENSEE's reasonable satisfaction, LICENSEE or its designee, rather
than Nastech, shall have the right, but not the obligation, to cause termination
of the Nastech Patent Infringement, including without limitation by suing and
otherwise asserting the Patent Rights and assuming control of actions not being
so diligently pursued. In addition to the foregoing, LICENSEE or its designee
shall also have such rights if a diminution or loss of rights or market position
would occur by the failure to file suit within a specified period of time
(including but not limited [***], and Nastech does not either file suit prior to
[***] before the expiration of such period of time or otherwise satisfy LICENSEE
(in LICENSEE's reasonable discretion) that Nastech will file suit before the
expiration of such period of time. Nastech shall cooperate and assist LICENSEE
in such actions, at Nastech's expense which shall be recouped in full [***],
including joining any lawsuits and similar proceedings as a party plaintiff and
taking such other actions as are required to bring or maintain such lawsuits and
proceedings. Nastech hereby grants, and shall grant, to LICENSEE an irrevocable
(during the term of this Agreement) power of attorney (coupled with an
interest), and such other authorizations, as may be necessary for LICENSEE and
its designees to pursue such actions; provided, however, that LICENSEE shall not
exercise such power to pursue any such action unless and until the conditions
set forth above in this Section 11.4(a)(iii) have been met.

(iv) Each Party shall have its related costs and expenses
reimbursed out of any recovery and the remainder of the recovery shall be
payable to LICENSEE and treated as Net Profits of the Product on which a royalty
is payable to Nastech in accordance with Article 6.

(v) Neither Party shall settle any claim, suit or action
involving a Nastech Patent Infringement in any manner that would negatively
impact upon the Patent Rights, or LICENSEE's rights or exclusivity under this
Agreement, without the mutual prior written consent of both Parties, not to be
unreasonably withheld or delayed. If LICENSEE or its designee takes action with
respect to a Nastech Patent Infringement under this Section 11.4, LICENSEE shall
receive a credit from Nastech for amounts due Nastech under this Agreement to
cover the actual costs incurred on a current basis of such action. Upon final
resolution of such action upon which LICENSEE receives any payment said payment
shall first go to reimburse LICENSEE for its unrecouped costs and then to
Nastech to the extent such credit was utilized, and then shall be payable to
LICENSEE and treated as Net Profits of the Product on which a royalty is payable
to Nastech in accordance with Article 6.

11.5. Ownership of Inventions. Each Party shall have and retain sole and
exclusive title to all inventions, discoveries and know-how made, conceived,
reduced to practice or generated solely by its employees, agents or persons
acting under its authority in the course of or as a result of this Agreement.
For the avoidance of doubt, all such inventions, discoveries, and know-how
directed to the Product made solely by or on behalf of Nastech shall be part of
the Patent Rights and Licensed Know-How. Any inventions, discoveries and
know-how which are conceived and reduced to practice jointly by employees,
agents or other persons acting under the authority of both parties in the course
of or as a result of this Agreement directed to the Product shall be the

sole property of LICENSEE, and Nastech hereby assigns, and shall assign, all
rights in and to same to LICENSEE, provided that Nastech shall thereby receive
from LICENSEE a worldwide, royalty free, nonexclusive license (with the right to
sublicense) in and to same for the performance of this Agreement and for all
other purposes that are not exclusive to LICENSEE or prohibited to Nastech under
Sections 2.1, 2.2, or 18.1.

12. Indemnification; Patent Infringement Claims.

12.1. Indemnification of LICENSEE. Nastech shall indemnify, defend and
hold the LICENSEE Indemnitees harmless from and against any and all Damages
which LICENSEE Indemnitees may incur, suffer or be required to pay as a result
of Third Party Claims asserted against any LICENSEE Indemnitee arising from or
relating to: (i) a breach of Nastech's obligations or representations or
warranties under this Agreement (including the Quality Agreement); (ii) the
negligence, recklessness or willful misconduct of Nastech, its Affiliates,
licensees or designees; (iii) any development (including for example, but not by
way of limitation, all activities related to pre-clinical and clinical
development, other studies or testing, or the toxicological, pharmacokinetic,
metabolic formulation, or clinical aspects of the Product) or Manufacturing
(including, but not limited to, Process Development/Validation Activities and
storage) performed by or under the authority of Nastech (except for Third Party
Claims for which LICENSEE is responsible under Section 12.2 below); (iv) Third
Party Claims that the Licensed Know-How disclosed by or under the authority of
Nastech or its Affiliates or designees to LICENSEE or its Affiliates or
sublicensees has been misappropriated; (v) any Claim with respect to any
infringement or misappropriation in the United States (or any other country in
which Nastech has obtained or is obligated to obtain a patent or made a patent
application) relating to the development, making, use, sale, offer for sale,
marketing, import, export or other exploitation of the Product hereunder; and
(vi) the enforcement of, or actions against, the Patent Rights.

12.2. Indemnification of Nastech. LICENSEE shall indemnify, defend and
hold the Nastech Indemnitees harmless from and against any and all Damages which
Nastech Indemnitees may incur, suffer or be required to pay as a result of Third
Party Claims asserted against any Nastech Indemnitee arising from or relating
to: (i) a breach of LICENSEE's obligations or representations or warranties
under this Agreement; (ii) the negligence, recklessness or willful misconduct of
LICENSEE, its Affiliates, sublicensees or designees; and (iii) the actions and
inactions of LICENSEE, its Affiliates or sublicensees in commercializing the
Product (except in the case of (i), (ii) or (iii) to the extent such Third Party
Claims are within the scope of Nastech's indemnification obligations under
section 12.1).

12.3. Notice. Each Party shall promptly notify the other of any Claim with
respect to which it expects to seek indemnification hereunder upon becoming
aware thereof and shall permit the other Party, at its cost, to defend against
such Claim and shall cooperate in the defense thereof. Neither Nastech nor
LICENSEE shall enter into, or permit, any settlement of any such Claim without
the prior written consent of the other Party, which consent shall not be
unreasonably withheld or delayed. The indemnified Party may, at its option and
expense, have its own counsel participate in any proceeding which is under the
direction of the indemnifying Party and will reasonably cooperate with the
indemnifying Party in the disposition of any such

matter. If the indemnifying Party hereunder does not defend any such Claim
within a reasonable time after notice thereof, the indemnified Party shall have
the right to defend the Claim itself and recover from the indemnifying Party as
additional damages all reasonable attorneys' fees and costs incurred by it
during the course of such defense.

12.4. Patent Infringement Claims.

(a) Each Party shall promptly notify the other if any legal
proceedings are commenced or threatened against either Party on the ground that
the filing of a document with or representation to any Regulatory Authority
relating to the Product or the manufacture, use, import, export, offer for sale,
sale or distribution thereof hereunder (each, an "Infringement Action"), is an
infringement of a Third Party's patent or other intellectual property rights.

(b) In the event that a Third Party brings an Infringement Action
against LICENSEE or Nastech in respect of the Product, LICENSEE shall, at its
own cost and expense, control and conduct the defense of such Infringement
Action in its sole discretion, provided such costs and expenses shall be
recouped in full [***]. In connection therewith, Nastech shall reasonably
cooperate with LICENSEE and at the request of LICENSEE provide LICENSEE with any
reasonably required assistance, including the provision and/or execution of any
related documents or instruments and testimony by Nastech's officers, employees
and agents, in connection with any such proceedings. LICENSEE shall, subject to
applicable privilege reasonably applied as to which reasonable actions, such as
joint defense agreements between Nastech and LICENSEE shall be taken, inform
Nastech's counsel of the progress, prosecution and defense of such Infringement
Actions and the court decisions rendered with respect thereto. LICENSEE shall
also, at its discretion and expense which shall be recouped in full [***], have
the right to seek a declaratory judgment of invalidity, non-infringement or
unenforceability of Third Party patents if there are no infringement proceedings
initiated by Third Parties regarding same.

12.5. Failure to Give Notice. The failure of a Party to give notice in
accordance with Section 12.3 or 12.4 shall not relieve the indemnifying Party of
its indemnification obligations hereunder except to the extent, if any, that it
is actually prejudiced thereby.

13. Insurance.

Each Party hereby represents to the other that it has, and during the term
of this Agreement will maintain, products liability insurance coverage of not
less than [***] US Dollars ($[***]) per occurrence and in the aggregate. Upon
the request of the other Party hereto, the insured party shall furnish the other
Party with a certificate of insurance evidencing such coverage and the insured
party hereby agrees that such insurance shall not be cancelled, materially
amended or allowed to lapse without at least [***] prior written notice to the
other Party hereto.

14. Term of Agreement; Termination; Bankruptcy.

14.1. Term of Agreement. The term of this Agreement shall commence
as of the Effective Date and shall continue in effect until the [***]
anniversary date of the Commercial Launch Date ("Termination Date"), provided
that this Agreement shall automatically renew for [successive five year periods]
unless terminated by a party at the end of [***] by notice to the other party
given at least [***] prior to the end of [***]; provided if Nastech gives such
notice to LICENSEE, such termination shall be subject to the effects described
in Section 14.6 (c) below.

14.2. Termination. Failure by either Party to comply with any of the
respective material obligations and conditions contained in this Agreement with
respect to the Product shall entitle the other Party to give the Party in
default notice requiring it to cure such default. If such default is not cured
within [***] of receipt of such notice, the notifying Party shall be entitled
(without prejudice to any of its other rights conferred on it by this Agreement
or under applicable law) to terminate this Agreement.

14.3. Bankruptcy or Insolvency.

(a) Either Party shall be entitled to immediately terminate this
Agreement upon the filing or institution of bankruptcy, reorganization (in
connection with any insolvency), liquidation or receivership proceedings, or
upon an assignment of a substantial portion of the assets for the benefit of
creditors by the other Party, or in the event a receiver or custodian is
appointed for such other Party's business, or if a substantial portion of such
other Party's business is subject to attachment or similar process; provided,
however, that in the case of any involuntary bankruptcy proceeding or the
attachment of a substantial portion of a Party's assets, such right to terminate
shall only become effective if the proceeding or attachment is not dismissed
within [***] after the filing thereof.

(b) In the event that Nastech as a debtor in possession, or a
trustee in bankruptcy under the U.S. Bankruptcy Code, 11 U.S.C. Sections 101 et
seq. (the "Bankruptcy Code"), rejects this Agreement or LICENSEE's right to
continue the licenses under this Agreement, LICENSEE may elect to retain its
license rights under this Agreement in accordance with Section 365(n) of the
Bankruptcy Code, provided LICENSEE continues to meet its obligations under this
Agreement and pays Nastech (or as otherwise directed by the Bankruptcy Court or
provided under the Bankruptcy Code) the amounts payable by LICENSEE hereunder,
minus (to the extent permitted by Section 365(n) of the Bankruptcy Code) any
costs incurred by LICENSEE in connection with its performance of obligations
required to be performed under this Agreement by Nastech and not performed by
it. Thereafter, in the manner provided for in Section 365(n) of the Bankruptcy
Code, neither Nastech as debtor in possession, nor a trustee in bankruptcy,
shall interfere with the license rights of LICENSEE under this Agreement.

14.4 [***]

14.5 Reference Product. [***] If the Agreement is Terminated due to this
Section 14.5 following the Commercial Launch Date, the LICENSEE shall take all
reasonable steps and efforts to assist NASTECH in assuming LICENSEE's
responsibilities in becoming the distributor in order to maintain the Products
market share.

14.6. Effect of Termination.

(a) In the event LICENSEE terminates this Agreement under Section
14.2 or 14.3, the Licenses granted to LICENSEE hereunder shall survive and
Nastech shall continue to use its best efforts to supply LICENSEE for a period
of [***] (the "Termination Supply Period") during which time LICENSEE shall be
free to change over manufacturing to a second source pursuant to Section 16.3.
Licensee's royalty obligation under Section 6.1 shall be reduced by one-half
from the amounts otherwise calculated hereunder and shall continue until the
termination of this Agreement (as it may have been extended in accordance with
Section 14.1) and the end of the Termination Supply Period. The terms of the
Quality Agreement shall apply for so long as Nastech supplies Product to
LICENSEE.

(b) In the event that Nastech terminates this Agreement under
Section 14.2 or 14.3, then the rights and licenses granted to LICENSEE under
Section 2.1 shall terminate and all rights to the Patent Rights, Licensed
Know-How, and the Product and all Regulatory Approvals and regulatory filings
(including applications for Regulatory Approvals) granted pursuant to this
Agreement shall revert or be assigned to Nastech, and LICENSEE shall execute all
documents and take such other actions as may be reasonably necessary to confirm
such reversion or assignment. Furthermore, (i) LICENSEE shall assign to Nastech
any and all trademarks being used exclusively for the Product and any domain
names containing such marks and (ii) LICENSEE shall use commercially reasonable
and diligent efforts, as reasonably requested by Nastech, to assign to Nastech
such sublicenses and/or subcontracts related to the Product or significant
services to be performed by Third Parties related to commercialization of the
Product. For the avoidance of doubt, Nastech shall not be required to provide
LICENSEE any consideration in exchange for the actions to be taken by it
pursuant to this Section 14.5(b); provided, however, that Nastech shall be
solely responsible for paying any royalties, fees or other consideration that
LICENSEE may be obligated to pay to a Third Party in respect of any sublicense
or subcontract.

(c) In the event Nastech terminates this Agreement under Section
14.1, the Licenses granted to LICENSEE hereunder shall survive and Nastech shall
continue to use its best efforts to supply LICENSEE until the end of the then
current term, during which time Nastech shall assist LICENSEE to qualify a
replacement manufacturer of the Product and LICENSEE shall be free to change
over manufacturing to such other manufacturer and thereafter utilize any other
manufacturer to make Product for the Territory. Licensee's royalty obligation
under Section 6.1 shall continue for so long as LICENSEE markets Product. The
LICENSEE shall be entitled to deduct the reasonable direct costs of implementing
such replacement manufacturer from Net Sales until the amount of such reasonable
direct costs has been recouped prior to resumption of the sharing of Net
Profits. The sharing of Net Profits shall resume at the then current profit
split as defined in Section 6.

(d) Termination of this Agreement shall be without prejudice to the
rights of the Parties and shall not release any payment, liability or other
obligation incurred between the Parties prior to the date of such termination or
arising as a result of such termination.

14.7. Surviving Terms. The provisions of Sections 6.1, 6.2, 6.3, 6.4, 9.2,
9.3, 9.4, 9.6,

10.4, 11.5, 12, 14, 15.1, 15.4, 16.1, 17, and 18 (excluding Section 18.1 and
18.2) of this Agreement shall survive any termination or expiration of this
Agreement and shall continue in full force and effect in accordance with their
respective terms. With respect to enforcement actions that commenced during the
term of this Agreement, Sections 11.4(a)(ii), (iii), (iv) and (v) shall survive
the termination or expiration of this Agreement, except to the extent that
LICENSEE does not desire to continue to pursue or remain involved in the
particular action. With respect to any such enforcement actions or Nastech
infringements under Section 11.4, where a Nastech Patent Infringement occurred
during the term of this Agreement, the distribution of recoveries shall be the
same as set forth in Section 11.4. Obligations for LICENSEE to make payments to
Nastech shall survive only to the extent that the payment became due and payable
by LICENSEE to Nastech during the term of this Agreement, subject to Section 6.3
and 6.4 above and the last sentence of this Section 14.5. Notwithstanding
anything to the contrary, if the Agreement is terminated prior to expiration,
other than termination by Nastech under Section 14.2 or 14.3, LICENSEE shall not
be required to accept delivery of, or to pay for, the Product not delivered in
accordance with this Agreement during the term prior to notice of termination by
LICENSEE. Subject to Section 14.6(a) all other terms and conditions of this
Agreement shall terminate and have no further force or effect. Subject to
Section 14.6(a) all terms and conditions of the Quality Agreement shall
terminate, and have no further force or effect, upon any expiration or
termination of this Agreement, except that such other obligations of Nastech
thereunder as necessary to enable LICENSEE to comply with any applicable legal
or regulatory requirements, shall survive. Notwithstanding any termination or
expiration of this Agreement, LICENSEE and its Affiliates and sublicensees shall
be entitled to continue to sell the Product inventories purchased by them prior
to the effective date of such termination or expiration, provided LICENSEE
continues to make the royalty payments with respect to such sales as are payable
by LICENSEE to Nastech under Section 6.1.

15. Confidentiality.

15.1. Confidentiality. During the term of this Agreement with respect to
the Product and for [***] after the termination, cancellation or expiration of
this Agreement, each Party shall maintain (and shall cause its Affiliates and
sublicensees to maintain) as confidential and all proprietary, technical,
marketing, pricing, financial or business information (including in the case of
LICENSEE, the Licensed Know-How) received from the other Party pursuant to this
Agreement ("Confidential Information") and shall only use such Confidential
Information in furtherance of this Agreement. Each Party agrees that any of its
Affiliates, licensees, sublicensees, officers, employees or agents provided or
given access to the other Party's Confidential Information shall be bound by
confidentiality obligations at least as restrictive as those set forth herein
and that it shall be fully responsible for the performance of the obligations
under this Article 15 by each such Person. The foregoing obligations of
confidentiality and use restrictions shall not apply, however, to the extent
that such Confidential Information:

(a) was known to the receiving Party, as evidenced by its written
records, prior to receipt from the other Party;

(b) is in the public domain at time of receipt or subsequently
enters the public domain through no breach of this Agreement by the receiving
Party;

(c) after the date of receipt from the disclosing Party, is received
without secrecy obligations from a Third Party with a bona fide right to
disclose it without violating any right of the disclosing Party;

(d) is independently developed by the receiving Party without the
aid, application or use of any of the disclosing Party's Confidential
Information;

(e) is required to be disclosed to Regulatory Authorities to
effectuate the purposes of this Agreement;

(f) is necessary to be disclosed to Third Parties for the
developing, making, using, selling, importing, exporting or other
commercialization of Product(s) (or for such Third Parties to determine their
interest in performing such activities) in accordance with this Agreement on the
condition that such Third Parties agree in writing to be bound by
confidentiality obligations and use restrictions at least as restrictive as
those contained in this Agreement; or

(g) is required to be disclosed by law or court order, provided that
notice is promptly delivered to the disclosing Party in order to provide the
disclosing Party sufficient opportunity to seek a protective order or other
similar order with respect to such Confidential Information and the receiving
Party thereafter discloses only such information as, in the reasonable opinion
of such Party's counsel, is required to be disclosed in order to comply with the
request, whether or not a protective order or other similar order is obtained by
the disclosing Party.

(h) is required in the reasonable opinion of a party's counsel to be
disclosed in order to comply with applicable securities laws or regulations. The
party's understand and agree that the terms and conditions of this Agreement are
confidential, but that it may be necessary for a Party to disclose this
Agreement and its terms and conditions or portions thereof in order to comply
with applicable securities laws and regulations.

15.2. Nastech Know-How. In view of the exclusive license granted to
LICENSEE hereunder, Nastech agrees to maintain in confidence and not to disclose
to Third Parties, such items or aspects of Nastech's Know-How as pertain
directly and specifically to the Product. It is understood, however, that this
Section 15.2 shall not prevent Nastech from using or disclosing such Know-How
for any product or purpose not expressly prohibited by this Agreement, if such
use and disclosure does not prejudice LICENSEE's rights or interests with
respect to the Product under this Agreement.

15.3. Return of Confidential Information. In the event of the expiration
or earlier termination of this Agreement, LICENSEE shall, upon the request of
Nastech, promptly return to Nastech all documents and materials comprising or
containing any Licensed Know-How relating to the Product that was provided by
Nastech to LICENSEE, or certify their destruction to Nastech. Similarly, in the
event of the expiration or earlier termination of this Agreement, Nastech shall,
upon the request of LICENSEE, promptly return to LICENSEE all documents,
materials, and Confidential Information of LICENSEE (including without
limitation of its

Affiliates, sublicensees, and contractors) that was provided by LICENSEE to
Nastech, or certify their destruction to LICENSEE. Notwithstanding the
foregoing, each Party shall have the right to retain a record copy of all
Know-How that it is required to return in accordance with the foregoing,
provided that such copy is not used by such Party except to document the
information disclosed to it by the other Party.

15.4. Disclosure of Third Party Confidential Material. Neither Party has
delivered nor will it deliver to the other Party confidential or proprietary
intellectual property or know-how of any Third Party without disclosing to the
other Party, in writing in advance of such disclosure, the source thereof and
such Party's right to make such disclosure.

16. Force Majeure; Back-Up Manufacturing.

16.1. Force Majeure. Neither Party shall be responsible or liable to the
other party for, nor shall this Agreement be terminated as a result of, any
failure to perform any of its obligations hereunder, if such failure results
from any unforeseeable event beyond such party's reasonable control such as
requisition or seizure by any government authority, wars, strikes, lockouts,
riots, disease, an act of God, civil commotion, fire, failure of public
utilities, common carriers or supplies, or any other similar circumstances. The
Parties shall use commercially reasonable and diligent efforts to avoid or
remove any such causes and shall resume performance under this Agreement as soon
as practicable whenever such cause is removed; provided, however, that the
foregoing shall not be construed to require either Party to settle any Third
Party dispute, to commence, continue or settle any litigation, or to incur any
unusual or extraordinary expenses.

16.2. Inability to Supply. Nastech shall immediately notify LICENSEE, if
Nastech is unable or unwilling, or anticipates being unable or unwilling, to
fill the Product order placed by LICENSEE.

16.3. Failure of Supply. Nastech hereby grants to LICENSEE, right and
license, in the Territory, during the term of this Agreement under the Patent
Rights and Licensed Know-How, with the right to grant and authorize sublicenses,
to make and have made from manufacturers other than Nastech, the Product.
LICENSEE agrees that it and its sublicensees will not exercise the rights under
this Section 16.3: until Nastech fails to meet LICENSEE's requirements for the
Product, such as without limitation by reason of a failure to meet stability,
quality, volume, labeling, or timing requirements, in LICENSEE's reasonable
judgment, and either (X) LICENSEE provides notice to Nastech that Nastech has
failed to meet LICENSEE's requirements (whether or not for the reasons described
in Section 16.1), and such failure is not cured by Nastech within the [***]
period following the date of such notice or (Y) Nastech has failed to meet
LICENSEE's requirements more than [***] in any [***] period. Without limiting
the foregoing, Nastech shall be considered to have failed to meet LICENSEE's
requirements for the Product if (i) Nastech has failed to supply in accordance
with this Agreement for more than [***] consecutive days after the original
requested delivery date at any time and for any reason (including, those
described in Section 16.1), (ii) Nastech shall have otherwise breached its
obligation under this Agreement to supply the Product, giving rise to LICENSEE's
right to terminate this Agreement under Section 14.2, or (iii) Nastech has
failed to supply to LICENSEE in accordance with this Agreement the Product
specified in purchase orders issued by

LICENSEE or its designee in accordance with Section 8.3 for any [***] shipments
in any [***] period (except for the reasons described in Section 16.1). For
purposes of the foregoing, only conforming Product received in a timely manner
and otherwise in accordance with this Agreement (including the Quality
Agreement) shall be considered supplied in accordance with this Agreement. The
exercise by Licensee of its rights under this Section 16.3 shall not diminish
LICENSEE's obligations under this Agreement, including without limitation under
Articles 5 and 6, except that the distribution of Net Profits to Nastech shall
be reduced by [***] if the applicable failure to supply under this Section 16.3
is due to any reason other than Force Majeure under Section 16.1. Additionally,
to the extent that Nastech fails to timely supply to LICENSEE at least [***]
percent ([***]%) of its ordered requirements of Product for the first [***]
following LICENSEE's scheduled Commercial Launch Nastech shall upon the request
of LICENSEE issue a credit against future profit sharing revenues for milestone
payments already made to Nastech pursuant to Section 5.1(iii), (iv), (v) or (vi)
and LICENSEE shall have no obligation to make any such milestone payments not
already paid.

16.4. Qualification of Back-Up Manufacturer. Notwithstanding any other
provision of this Agreement, in order to avoid delays, Product shortages and
losses which could be caused by an inability, refusal or other failure of
Nastech to meet LICENSEE's requirements for Product at any time, LICENSEE has
and shall have the right at LICENSEE's sole cost and expense, with the full
cooperation and assistance of Nastech, to qualify and validate itself or another
back-up manufacturer for the Product in order to insure that LICENSEE will at
all times have continuity of supply of the Product in the event that Nastech is
unable or unwilling to meet its requirements at any time.

17. Dispute Resolution.

17.1. Intent. The Parties recognize that disputes as to certain matters
may from time to time arise which relate to a Party's rights and/or obligations
under this Agreement. It is the objective of the Parties to establish procedures
to facilitate the resolution of such disputes in an expedient manner by mutual
cooperation and without resort to litigation. To accomplish this objective, the
Parties agree to follow the procedures set forth in this Article 17 if and when
such a dispute arises between the Parties relating to this Agreement.
Notwithstanding the provisions of this Article 17, however, nothing herein
contained shall preclude a Party from seeking equitable remedies in court; the
Parties agree that all proceedings shall be brought in a court located in New
York, New York, and waive objections as to venue and jurisdiction with respect
thereto.

17.2. Negotiation. If any controversy, dispute or claim arises between the
Parties relating to the interpretation, breach, performance, enforcement,
termination or validity of this Agreement and the Parties cannot resolve the
dispute within [***] of a written request by one Party to the other Party, the
Parties agree to hold a meeting, attended by the Chief Executive Officer or
President, or a Vice President designated by him, of each Party, to attempt in
good faith to negotiate a resolution of the dispute prior to pursuing other
available remedies.

18. Miscellaneous.

18.1. Nastech Product Restriction. During the term of this Agreement
neither Nastech nor its Affiliates shall develop, manufacture, market, import,
export, sell, or offer to sell any [***]. Additionally, neither Nastech nor its
Affiliates shall provide any funding or Know-How during the term of this
Agreement to Third Parties for the specific purpose of, or grant a license or
other authorization to or otherwise assist or facilitate any Third Party to,
develop, manufacture, market, import, export, sell, or offer to sell any [***].
Nastech shall include, and cause its Affiliates to include, in any grant or

or otherwise assist or facilitate Third Parties for the specific purpose
thereof.

18.3. Amendments. No amendment or modification of the terms of this
Agreement shall be binding on either Party unless reduced to writing and signed
by both Parties.

18.4. No Waiver. The failure of either Party to enforce any provision of
this Agreement at any time or for any period of time shall not be construed to
be a waiver of any right of either Party hereunder nor to prevent the subsequent
enforcement thereof or of any other provision hereof in accordance with its
terms. Except as otherwise herein expressly provided, no remedy specified in
this Agreement is intended as an exclusive remedy and shall be in addition to
any other remedies that may be available.

18.5. Execution of Additional Documents. Each Party hereto agrees, without
charge, to promptly execute and deliver such further applications, assignments,
descriptions and other instruments and documents and otherwise to cooperate with
the other Party as may be reasonably necessary or desirable to effect the
purpose of this Agreement and carry out its provisions.

18.6. Entire Agreement. This Agreement constitutes the entire
understanding between the Parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous contracts, agreements and

Agreement.

18.8. Assignment. Except as expressly authorized in this Agreement,
neither Party shall assign or otherwise transfer this Agreement, or its rights
or obligations under this Agreement without the prior written consent of the
other Party, provided, however, that: (a) the foregoing shall not affect the
