of all meetings for that committee in each calendar year shall be held in person. Meetings of a
committee shall be effective only if at least one representative of each Party is present or
participating. Each Party shall be responsible for all of its own expenses of participating in
committee meetings. Each Party shall use good faith and cooperative efforts to facilitate and
assist the efforts of the committees.

          (c) Each committee shall continue to exist until the first to occur of (i) the Parties
mutually agreeing to dissolve it, (ii) the expiration of all payment obligations described in
Article 7, or (iii) Alexza providing to Endo written notice of its intention to dissolve and no
longer participate in such committee. In any event, at any time Alexza may terminate its
participation on any committee, on thirty (30) days’ written notice. Unless the Parties agree
otherwise in writing at the time, upon dissolution of such committee, Alexza’s powers and duties
shall automatically be assumed by Endo; provided, however, Alexza shall have a right to approve
(such approval not to be unreasonably withheld or delayed) any decisions made by Endo after the
dissolution of such committee, to the extent that Alexza would have had the right to make a final
decision on such matter pursuant to Section 2.1(d)(ii) had Alexza not terminated its participation
on the committee.

ARTICLE 3

DEVELOPMENT PROGRAM

     3.1 Overview of Development. The Parties shall undertake the development of Product in a
collaborative and efficient manner in accordance with this Article 3. The pre-clinical and
clinical development of Product in the Territory under this Agreement shall be governed by a
written development plan (the “Development Plan”), as such Development Plan may be revised from
time to time in accordance with Section 3.2(a).

     3.2 Development Plan.

          (a) Development Plan. Within three (3) months following the Effective Date, the JDC shall
develop an initial Development Plan, which will contain detailed provisions governing all
pre-clinical and clinical development, budgets and timelines, manufacturing, and regulatory work to
be performed to obtain Regulatory Approval of the Initial Product. The Development Plan shall be
subject to final approval by Endo, except that, subject to Section 2.1(d)(ii), the Device design,
development and manufacturing portion of the Development Plan shall be subject to final approval by
Alexza. As long as the Product is being developed, the JDC shall review the Development Plan at
least annually and may, from time to time, provide comments to and/or generate a proposed revised
version of the Development Plan that is consistent with the terms of this Agreement and the goals
of the Parties’ collaborative development of the Product, which revised version shall be submitted
to the JSC for approval as set forth above. The JSC shall give good faith consideration to any
comments and/or revisions provided by the JDC with respect to the Development Plan, but the final
determination as to
what changes and/or revisions shall be made to any Development Plan shall be made by the JSC,

been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

subject to the provisions of Section 2.1(d) in the case of any deadlock among the members of the
JSC. Once approved by the JSC, such revised Development Plan shall replace the prior Development
Plan. The Development Plan shall allocate between the Parties responsibility for each
development-related activity described therein in a manner consistent with Section 3.3. The
Development Plan shall in no event be amended in a manner that would require either Party to
perform any assignment or task in a manner that would violate any applicable law or regulation. In
the event of a change in any applicable law or regulation, the Parties shall work together to amend
the Development Plan to enable each Party to comply fully with such law or regulation. If such
amendment is not approved, the affected Party would be excused from performing any activity
specified in the Development Plan that would violate or result in a violation of any applicable law
or regulation.

          (b) Performance of Development Plan. The Parties shall use Commercially Reasonable Efforts to
conduct their respective tasks assigned pursuant to the Development Plan and to attempt to achieve
the objectives of the Development Plan. Each Party shall perform its obligations under the
Development Plan in a professional manner, and in compliance in all material respects with the
Development Plan and the requirements of applicable laws and regulations and all applicable good
clinical and manufacturing practices. Changes in the scope or direction of the development work
under this Agreement that would require a material deviation from the Development Plan must be
approved by the Parties as set forth in Section 3.2(a).

     3.3 Responsibilities of the Parties.

          (a) Endo shall have primary responsibility for implementing the clinical and pre-clinical
development and non-manufacturing regulatory aspects of the Development Plan as set forth in
greater detail in this Article 3 and Article 4.

          (b) Alexza shall have primary responsibility for Device design and development (other than
pre-clinical and clinical development), design implementation, all other Device-related aspects of
the Development Plan, and all manufacturing activities with respect to Product, subject to the
provisions of and as set forth in greater detail in this Article 3 and Articles 4 and 5. Such
responsibilities shall include: (i) the design, development and testing of the Device for use in a
Product, (ii) performance of CMC activities for a Product, and (iii) manufacture and supply of
Clinical Trial Materials for use in Pre-Clinical Trials and Clinical Trials. Notwithstanding
anything to the contrary in this Agreement, Alexza’s responsibility to conduct development work and
to pay development costs under Section 3.5 shall terminate upon receipt of Regulatory Approval for
the Initial Product for the treatment of breakthrough pain in cancer patients and the treatment of
breakthrough pain in non-cancer patients (it being understood that Alexza’s responsibility to
conduct development work and pay development costs under Section 3.5 shall continue prior to
receipt of Regulatory Approval for so long as development work for Regulatory Approval continues
for such indications), except that Alexza’a responsibilities shall continue in respect to all
Clinical Trials necessary to support registration of such Product for such indications.

 

			
	[ * ] =	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

          (c) Notwithstanding anything to the contrary in this Agreement, unless Alexza agrees otherwise
in writing, Alexza shall have no obligation to perform any work in connection with, or in support
of, (i) any Non-Registrational Trial of the Initial Product, (ii) the design, development, or
manufacturing, of any Products other than the Initial Product, or (iii) any Clinical Trials for an
indication other than each indication included in the Initial Indication (it being understood that
Alexza’s responsibility for each such indication shall continue so long as Regulatory Approval for
such indication continues to be sought or has been obtained (where Regulatory Approval has been
obtained, to the extent relating to Clinical Trials to support registration)).

     3.4 Third Party Contractors. Either Party shall be free to subcontract to Third Parties
(“Subcontractors”) any of its obligations under this Agreement; provided, however that (a) with
respect to any such Subcontractor that will be manufacturing major components for Product or
overseeing or conducting Pre-Clinical Trials and Clinical Trials or toxicology studies for Product,
the applicable Party shall notify the other Party in writing upon retaining such Subcontractor; (b)
each Party shall enter into agreements with its Subcontractors that contain confidentiality terms
at least as strict as those set forth in Article 10 hereof; and (c) no such subcontracting shall
relieve a Party of its obligations hereunder. In addition, in the event that Alexza subcontracts
with a Third Party to manufacture, test and/or package Product for use in the Territory, Endo shall
be given the opportunity to review and comment on such manufacturing agreement in advance of its
execution, and Alexza shall give good faith consideration to Endo’s comments. Such Third Party
manufacturing agreement(s) shall provide that Endo shall be an intended third party beneficiary of
such Third Party manufacturer’s obligations to Alexza with respect to Product thereunder, including
with rights of direct enforcement by Endo. In addition, each Third Party manufacturing agreement
for Product for use in the Territory shall provide, in substance, that, in the event that Alexza,
or any other Person acting on behalf of Alexza or its estate pursuant to any bankruptcy laws, shall
seek or obtain a bankruptcy rejection of such Third Party manufacturing agreement, then the Third
Party manufacturer shall (i) timely exercise its rights to continue any and all licenses (if any)
thereunder relating to the Product in the Territory, and (ii) to the extent that bankruptcy
rejection effectively terminated the Third Party manufacturing agreement, immediately enter into an
agreement with Endo for Product in the Territory on substantially the same terms and conditions as
those contained in the agreement with Alexza. The Third Party manufacturing agreements may contain
such additional terms and conditions as Alexza and the Third Party manufacturer shall agree to,
subject to the review (but not the approval) of Endo prior to the execution of such Third Party
manufacturing agreement and provided that such additional terms and conditions do not prejudice,
reduce or limit performance by such Third Party manufacturer under this Agreement.

     3.5 Development Costs. Each Party shall be responsible for all internal costs and expenses
incurred by or on behalf of such Party or its Affiliates in connection with development of the
Initial Product pursuant to the Development Plan hereunder. Alexza shall be responsible for all
out-of-pocket expenses for Device design and development (other than pre-clinical and clinical
development after the Effective Date), design implementation, all other Device-related aspects of
the Development Plan with respect to the Initial Product, and all manufacturing activities with
respect to the Initial Product. Except as set forth in the following sentence, after the Effective
Date Endo shall be responsible for all out-of-pocket expenses payable to Third

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

Parties incurred by Endo or its Affiliates in connection with pre-clinical, clinical, and
regulatory development of the Initial Product pursuant to the Development Plan (“External PC&R
Costs”). Endo and Alexza shall be responsible for [ * ] and [ * ], respectively, of External PC&R
Costs in excess of [ * ]; provided, however, that Alexza’s responsibility for External PC&R Costs
shall not exceed a total of twenty million dollars ($20,000,000). Notwithstanding the foregoing,
Alexza shall not be responsible for any costs associated with any Clinical Trial for an indication
other than each indication included in the Initial Indication (it being understood that Alexza’s
responsibility to pay costs shall continue in respect to each such indication in the Initial
Indication for which Regulatory Approval continues to be sought) or with a Non-Registrational
Trial, and such costs shall not be included in External PC&R Costs for the purpose of determining
whether External PC&R Costs exceed the foregoing [ * ] threshold. Any request or claim by Endo for
reimbursement of External PC&R Costs shall be invoiced on a quarterly basis and shall be calculated
in accordance with GAAP consistently applied by Endo. Such invoices shall be in reasonable detail
and shall be due forty five (45) days after Alexza’s receipt thereof. To the extent that Endo
desires to undertake the pre-clinical or clinical development of Products other than the Initial
Product, the Parties shall discuss in good faith the manner in which any costs associated with such
development or regulatory, design, testing, or manufacturing activities related to such development
shall be paid.

     3.6 Development Guidelines.

          (a) General. In all matters related to implementation of the Agreement, the Parties shall be
guided by standards of reasonableness in economic terms and fairness to each of the Parties,
striving to balance the legitimate interests and concerns of the Parties and further the
development of the Product.

          (b) Independence. Subject to the terms of this Agreement, the activities and resources of
each Party shall be managed by such Party, acting independently and in its individual capacity.
The relationship between Alexza and Endo is that of independent contractors and neither Party shall
have the power to bind or obligate the other Party in any manner, other than as is expressly set
forth in this Agreement.

     3.7 Generic Product. In no event shall Endo develop or manufacture a Generic Product intended
for sale in the Territory or sell or otherwise commercialize a Generic Product in the Territory.

ARTICLE 4

Reasonable Efforts to obtain Regulatory Approvals in the U.S. for Product for one or both
indications included in the Initial Indication (as determined by Endo) and for any other
indications that Endo decides to pursue. If and when Regulatory Approvals are secured in the U.S.,
Endo shall thereafter make a determination as to whether to pursue Regulatory Approvals in Canada
and Mexico, which determination shall be left to Endo’s sole discretion. If Endo decides to pursue
Regulatory Approvals in Canada and/or Mexico, Endo shall use Commercially Reasonable Efforts in
furtherance thereof. Subject to Section 4.2, all Regulatory Submissions for Product shall be filed
in the name of Endo or one of its Affiliates or sublicensees, and, as between the Parties, Endo
shall be responsible for all communications and other dealings with the Regulatory Authorities
relating to Product in the Territory. Endo shall be the legal and beneficial owner of all
Regulatory Submissions and Regulatory Approvals for Product in the Territory. No later than thirty
(30) days following the Effective Date, Alexza shall transfer to Endo any INDs for AZ-003 that are
Controlled by Alexza as of the Effective Date. For clarity, development outside of the U.S. within
the Territory shall be at the sole discretion of Endo.

          (b) Endo shall develop and implement procedures for drafting and review of any IND, New Drug
Application, or other planned Regulatory Submission for a Product, which shall provide Alexza, to
the extent reasonably practicable, a period of not less than ten (10) days to provide substantive

and shall revise each such Regulatory Submission to reflect any comments provided by Alexza that
Endo, in its reasonable discretion, shall deem necessary and/or appropriate to include in such
Regulatory Submission.

          (c) Endo shall promptly notify Alexza of all Regulatory Submissions that it submits, and, at
Alexza’s written request, shall promptly provide Alexza with a copy (which may be wholly or partly
in electronic form) of such Regulatory Submissions. Endo will provide Alexza with reasonable
advance notice of any scheduled meeting between Endo or its Affiliate or sublicensee with any
Regulatory Authority relating to a Product, and Alexza shall have a right to have up to two (2)
Alexza employees or contractors attend, and, at the request of Endo, participate in, any such
meeting. Endo also shall promptly furnish Alexza with summaries of all material correspondence or
material meetings with any Regulatory Authority in the Territory relating to a Product, and Endo
shall, at Alexza’s written request, promptly furnish Alexza with copies of such correspondence or
copies of minutes of such meetings.

          (d) Following receipt of Regulatory Approval for a Product in the Territory, Endo shall retain
primary responsibility for dealings with the applicable Regulatory Authority with respect to such
Product, including filing all supplements and other documents with such Regulatory Authority with
respect to such Regulatory Approval in the Territory.

          (e) To the extent permitted by law, Alexza and its Affiliates, and any licensee of Alexza
from which Alexza has obtained a corresponding right for Endo and its Affiliates (which Alexza
shall use Commercially Reasonable efforts to obtain), shall have a right of reference outside of
the Territory to all Regulatory Submissions filed by, and Regulatory Approvals received by, Endo
with respect to the Initial Product in the Territory upon payment by Alexza or such licensee to
Endo of (i) [ * ] of Endo’s External PC&R Costs allocable to such Regulatory Submissions in the
case such Regulatory Submissions are to be referenced in any

countries in the European Union, and (ii) [ * ] of Endo’s External PC&R Costs allocable to
such Regulatory Submissions in the case such Regulatory Submissions are to be referenced in any
countries outside the Territory and outside the European Union. To the extent permitted by law,
Endo and its Affiliates shall have a right of reference to all Regulatory Submissions filed by, and
Regulatory Approvals received by, Alexza and any licensee of Alexza from which Alexza has obtained
a corresponding right for Endo and its Affiliates (which Alexza shall use Commercially Reasonable
Efforts to obtain) with respect to any Product outside the Territory upon payment by Endo to
Alexza or such licensee of [ * ] of the out-of-pocket costs and expenses paid to a Third Party by
Alexza or such licensee for such Regulatory Submissions. Both Alexza and Endo may exercise their
respective rights under this Section 4.1(e) with respect to Regulatory Submissions on a Clinical
Trial-by-Clinical Trial basis (including toxicology studies), in which case the payments described
above shall be calculated based on the External PC&R Costs (in the case of an exercise by Alexza)
or out-of-pocket costs and expenses paid to a Third Party (in the case of an exercise by Endo)
allocable to the Regulatory Submissions for each such Clinical Trial.

          (f) Except as set forth in Section 4.2(b), all Regulatory Submissions in the Territory and all
safety and other data related thereto shall be deemed to constitute Endo Confidential Information
and shall be subject to Article 10; provided, however, that the foregoing shall not limit Alexza’s
right to use, for any product other than a Product, all Product-related pre-clinical and clinical
data generated by, on behalf of, or for Alexza prior to the Effective Date.

     4.2 Manufacturing-Related Regulatory Submissions

          (a) Notwithstanding Endo’s obligation to submit Regulatory Submissions as set forth in Section
4.1(a), Alexza shall be responsible for compiling CMC information pertaining to Product for
inclusion in Regulatory Submissions. Endo shall provide to Alexza the CMC portion of the Regulatory
Submissions for completion by Alexza. Alexza shall promptly complete and provide the necessary
information to Endo and Endo will include the CMC information provided by Alexza in Endo’s
Regulatory Submissions.

          (b) All CMC information compiled by Alexza pursuant to Section 4.2(a) shall be deemed to be
Alexza Confidential Information and shall be subject to Article 10.

          (c) Adverse Event Reporting.

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

               (ii) Alexza shall be responsible for establishing and maintaining a global safety database.

          (d) Promptly following the Effective Date, but in no event later than sixty (60) days
thereafter, Endo and Alexza will develop and agree upon safety data exchange procedures in a
separate and detailed safety agreement (the “Safety Agreement”). Such agreement will describe the
coordination of collection, investigation, reporting, and exchange of information concerning
adverse events or any other safety problem of any significance, and product quality and product
complaints involving adverse events, sufficient to permit each Party, its Affiliates, sublicensees
or licensees to comply with its legal obligations. The safety data exchange procedures will be
promptly updated if required by changes in legal requirements.

     4.3 Regulatory Correspondence.

          (a) Notification to Other Parties of Regulatory Correspondence. Each Party shall promptly
(and in any event, within five (5) Business Days of the date of receipt of notice) notify the other
Party in writing of, and shall provide the other Party with copies of, any correspondence and other
documentation received or prepared by such Party in connection with any of the following events:
(i) receipt of a material regulatory letter, warning letter, Form 483, or similar item, from any
Regulatory Authority directed to the manufacture, packaging, and/or storage of a Product, or Alexza
facility or contract manufacturing facility associated with Alexza’s supply of Product hereunder;
(ii) any recall or correction of any batch of the Drug; and (3) any regulatory comments relating to
a Product requiring a response or action by a Party.

          (b) Regulatory Correspondence Requiring an Alexza Response. In the event that Alexza receives
any material regulatory letter or comments from any Regulatory Authority directed to its
manufacture of a Product requiring a response or action by Alexza, including, but not limited to,
receipt of a Form 483 or a warning letter, Endo (as applicable) will promptly provide Alexza with
any data or information required by Alexza in preparing any response relating to Alexza’s
manufacture of such Product, and will cooperate fully with Alexza in preparing such response. To
the extent reasonably practicable (subject to the time a response is mandated), Alexza shall
provide Endo with a copy of each such response for Endo’s review and comment at least five (5)
Business Days prior to Alexza’s submission of the response. Alexza shall give good faith
consideration to any Endo comments to each such proposed Alexza response and shall incorporate such
comments to the extent Alexza deems necessary or appropriate. Endo shall have the final decision
with respect to any responses or actions required by such letter or comments which relate to the
pre-clinical and clinical development, commercialization and regulatory aspects of the Product.

          (c) Regulatory Correspondence Requiring an Endo Response. In the event that Endo receives any
material regulatory letter or comments from any Regulatory Authority relating to the manufacture of
a Product, Alexza (as applicable) will promptly provide Endo with any data or information required
by Endo in preparing any response relating to Alexza’s manufacture of a Product, and will cooperate
fully with Endo in preparing such response. To the extent reasonably practicable (subject to the
time a response is mandated), Endo shall provide Alexza with a copy of each such response for
Alexza’s review and comment

 

			
	[ * ] =	 	  Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

at least five (5) Business Days prior to Endo’s submission of the response. Endo shall give
good faith consideration to any Alexza comments to each such proposed Endo response and shall
incorporate such comments to the extent Endo deems necessary or appropriate. Alexza shall have the
final decision with respect to any responses or actions required by such letter or comments which
relate to manufacture of the Product.

     4.4 Inspections. In the event that the Alexza facility or contract manufacturing facility will
be inspected by representatives of any Regulatory Authority directed to Alexza’s manufacture of
Product or Clinical Trial Material, Alexza shall notify Endo promptly after learning of such
inspection, and shall supply Endo with copies of any correspondence or portions of correspondence
which relate to Product. Following any such inspection, Alexza shall provide Endo with a written
summary of that portion of the inspection that was relevant to Product or Clinical Trial Material
within seven (7) Business Days of such inspection.

     4.5 Product Recalls and Withdrawals. In the event that a Party becomes aware that a Product
may not comply with applicable law, rules or regulations (either by notification from a Regulatory
Authority or otherwise) in the Territory and/or that a recall or withdrawal of a Product in the
Territory is desirable, such Party shall promptly notify the other Party. Promptly after Endo
receives such notice from Alexza (if Alexza is the Party that first becomes aware of the
necessity/desirability of a Product recall or withdrawal) or promptly after Endo first becomes
aware of the necessity/desirability of a Product recall or withdrawal (if Endo is the Party that
first becomes so aware), Endo shall undertake an appropriate investigation, give good faith
consideration to all substantive comments provided by Alexza, and make a determination with respect
to the disposition of any such matter, including determining whether the applicable Product in the
Territory shall be recalled or withdrawn. If Endo determines that a Product in the Territory shall
be recalled, Endo shall develop and implement a plan to conduct such recall. The Party that is
predominantly responsible for the applicable Product’s non-compliance with applicable laws, rules
and regulations shall bear all costs and expenses associated with conducting such recall in
accordance with such recall plan, unless such recall results predominantly from the other Party’s
material breach of its obligations under this Agreement or unless such recall otherwise
predominantly results from the gross negligence or wrongful intentional acts or omissions of the
other Party, in which case the other Party shall bear all costs and expenses associated with such
recall. In all cases, each Party shall use Commercially Reasonable Efforts to implement any recall
of any Product in the Territory.

     4.6 Regulatory Updates. During the Term, Endo will keep Alexza generally apprised of the
status of any Regulatory Submissions related to a Product in the Territory. Endo shall immediately
notify Alexza in writing upon receipt by Endo or its sublicensee(s) of any Regulatory Approval to
market a Product for any indication in the Territory. Correspondingly, Alexza shall immediately
notify Endo in writing upon receipt by Alexza or its sublicense(s) of any Regulatory Approvals to
market Product for any indication outside the Territory.

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

[ * ] of its manufacturing capacity to Endo’s Purchase Orders in priority to any other Person’s
orders. In no event shall Alexza manufacture a Generic Product for sale in the Territory.

               (iv) Clinical Trial Materials shall be supplied to Endo as specified in the Development Plan.

          (b) Forecasts; Orders of Product.

               (i) No later than [ * ] prior to January 1 of each year following the First Commercial Sale
of a Product in the Territory, Endo shall deliver to Alexza a non-binding [ * ] forecast of Endo’s
unit requirements for Product for each year during that period. Such long-term forecast shall
thereafter be updated at least once every [ * ] during the Term.

               (ii) No later than [ * ] prior to the expected First Commercial Sale, Endo and Alexza shall
discuss in good faith the quantities of Product forecasted to be necessary to support commercial
launch. No later than [ * ] prior to the First Commercial Sale, Endo shall submit to Alexza a
written forecast of its monthly requirements for Product for each of the next succeeding [ * ].
The forecast shall be updated [ * ].

               (iii) The forecast of the most current [ * ] period shall always constitute a firm order by
Endo for the [ * ] forecasted requirements. Endo shall submit a Purchase Order to Alexza with
respect to such firm order (a “Purchase Order”) with not less than sixty (60) days lead time prior
to a requested Delivery Date for the first nine months following First Commercial Sale, and ninety
(90) days lead time thereafter, which Purchase Order shall state in detail the required amounts and
related Delivery Dates, and shall be binding on the Parties regarding Products to be purchased.
Alexza shall have ten (10) days to accept or reject such order for failure to conform to the firm
order quantity or failure to comply with the lead time requirements, with failure to respond being
deemed acceptance. The forecast for the remaining
[ * ] period of each rolling forecast is for planning purposes only and shall not constitute a
commitment to purchase or supply Product. In the event that Endo does not ultimately purchase the
forecast quantities for the binding [ * ] period representing a firm order, then as of the last day
of the end of the month in such [ * ] period in which a firm order is not completed with Purchase
Orders during such period Endo shall be deemed to have provided a Purchase Order for the amount of
Product equal to (A) the applicable firm order amount less (B) the previously ordered amounts
represented by Purchase Orders for the applicable [ * ] (the “Final Firm Order Commitment”). The
Final Firm Order Commitment shall have a Delivery Date that is sixty (60) days from end of the
month in which the Final Firm Order Commitment is deemed to occur. Notwithstanding the foregoing,
Endo may cancel without penalty any and all Purchase Orders in the event Alexza is unable to
fulfill any outstanding Purchase Order within ninety (90) days of its scheduled Delivery Date due
to a force majeure event.

               (iv) Endo shall have the right to reasonably approve suppliers selected by Alexza for the
provision of Raw Materials for use in the Clinical Trial Materials and Product. Alexza shall be
permitted to purchase Raw Materials for the Manufacture of Product using the forecast of the most
current [ * ] period in the [ * ] Product forecast. Should any Raw Materials purchased based on
this [ * ] forecast become obsolete or unusable as a result of subsequent

been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

changes to Endo’s forecast quantities or to Product Specifications, then Endo shall, at Endo’s
option, purchase from Alexza at Alexza’s acquisition cost, the amount of inventory of Raw Materials
so rendered obsolete (including related costs for destruction), or, if possible, have Alexza return
such materials and reimburse Alexza any restocking fees incurred.

               (v) Should any Purchase Order include volume of Product in amounts that exceed [ * ] of
amounts set forth in the most recent forecast provided by Endo to Alexza pursuant to Section
5.1(b)(ii) hereof, or should Endo desire to increase the amount of Product to be purchased pursuant
to any already submitted Purchase Order, then Alexza shall use Commercially Reasonable Efforts to
meet such excess Product request. Notwithstanding the foregoing, Alexza shall not be liable to Endo
for any inability, despite its Commercially Reasonable Efforts, to manufacture and deliver such
excess Product.

          (c) Purchase of Product; Deliveries.

               (i) Endo shall place Purchase Orders only in whole Batch quantities. Alexza shall furnish to
Endo with each shipment of Product ordered by Endo hereunder, (A) a certificate of analysis
reflecting that such Product conforms to the relevant Specifications and (B) all documentation
required by law, Regulatory Requirements or any Regulatory Authority having jurisdiction over such
shipment.

               (ii) Endo shall not be required to take receipt of a Batch of Product with less than [ * ]
expiry or [ * ] of the original shelf life, whichever is greater, except that in the event that the
Product receives an original shelf life of [ * ] or less, the qualification as to [ * ] of the
original shelf life shall not apply to Product delivered in respect to a Purchase Order that has a
Delivery Date within [ * ]. Endo and Alexza may nonetheless negotiate in good faith for Endo to
purchase such Batches.

               (iii) Property in, title to and risk of loss of or damage to Product shall remain with Alexza
and pass to Endo only upon delivery EXW (Incoterms) Alexza’s Plant shipping dock in the U.S. to a
carrier designated by Endo. Product shall be prepared by Alexza for shipment in accordance with
mutually agreed shipping and packing specifications and all shipments shall be accompanied by
appropriate transportation and other agreed upon documentation.

               (iv) In the event that any Product shall fail to conform in all material respects with any
Purchase Order, any warranty, the Quality Agreement and/or the Specifications, Endo shall have the
right to reject such Product by giving written notice to Alexza within thirty (30) days after
receipt by Endo in the case of patent defects in such Product and thirty (30) days from the date
when Endo learned of such defects in the case of latent defects in such Product. Any notice given
hereunder shall specify in writing the manner in which the Product fails to conform to the Purchase
Order or fails to meet such warranty or the Specifications.

                    (1) If it is determined by agreement of the Parties (or in the absence of agreement of the
Parties, by a mutually acceptable independent laboratory or

 

			
	[ * ] =	 	  Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

consultant whose fees shall be paid by the non-prevailing Party) that the non-conformity is
due to damage to the Product (i) caused by Endo or its agents or customers or (ii) which occurs
subsequent to delivery of such Product to Endo’s carrier at the Plant in the U.S., Alexza shall
have no liability to Endo with respect thereto. In all other instances following the determination
by agreement of the Parties (or in the absence of agreement of the Parties, by a mutually
acceptable independent laboratory or consultant whose fees shall be paid by the non-prevailing
Party) that Alexza is responsible for the non-conformity, Endo shall be entitled, in addition to
any other remedies it may have, to prompt replacement by Alexza of such non-conforming Product with
conforming Product at no additional cost to Endo. In the case of non-conforming Product for which
Alexza is responsible as provided above at a time when Endo has no additional quantities of Product
on order with Alexza, Alexza shall pay to Endo a credit in an amount equal to the amount paid by
Endo to Alexza for such Product, plus associated shipping and insurance charges.

                    (2) In any case where Endo rejects non-conforming Product, Endo shall await written
instructions from Alexza as to further disposition of the non-conforming Product. If Alexza does
not provide such instructions within ninety (90) days of receipt of Endo’s rejection notice, Endo
shall dispose of the Product and invoice Alexza for the costs of destruction. In any event, Endo
may retain samples of non-conforming Product for the purpose of determining any dispute.

               (v) In the event Endo elects to accept Product that is delivered after the Delivery Date
specified in the applicable Purchase Order, Endo may, in addition to any other remedies available
to it, commencing on the eleventh (11th) day after the specified Delivery Date, charge
Alexza for each seven day period thereafter that the delivery is late a late delivery charge equal
to [ * ] of royalties payable by Endo in respect to such Product for the first seven day period, [
* ] of royalties payable by Endo in respect to such Product for the second seven day period, and [
* ] percent of royalties payable by Endo in respect to such Product for each subsequent seven day
period, up to a maximum late delivery charge of [ * ] of royalties in respect to such Product.
However, no late fee shall accrue on any Product delivered (i) pursuant to a Purchase Order
accepted by Alexza pursuant to Section 5.1(b)(v) or (ii) within thirty (30) days after the Delivery
Date specified in the applicable Purchase Order if the Purchase Order has a Delivery Date within
ninety (90) days after [ * ] and includes a volume of Product that is in excess of the amounts set
forth in the forecast provided by Endo to Alexza
[ * ].

               (vi) Endo shall pay Alexza a transfer price of [ * ] per controller included in the Initial
Product and [ * ] per cartridge of Drug included in the Initial Product in respect to Initial
Product acquired by Endo to be sold in the First Commercial Sale [ * ]. In no event shall Endo be
required to pay Alexza for the supply of any Raw Materials, Clinical Trial Materials or other
Product hereunder unless otherwise agreed by Endo. Payments due by Endo to Alexza under this
paragraph are due forty five (45) days from the date of Alexza’s invoice, which invoice shall be
sent out concurrently with shipment of Product.

          (d) Capacity. Alexza covenants that it will have the capacity to Manufacture up to [ * ]
controllers and [ * ] cartridges of Drug for the Initial Product per year for Endo (the

 

			
	[ * ] =	 	  Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

“Volume Commitment”) in the event that Endo forecasts such quantities. Alexza shall use its
Commercially Reasonable Efforts to ensure that all of Endo’s Product requirements in excess of the
Volume Commitment are met. In the event that Alexza in its reasonable judgment based on the
forecast provided pursuant to Section 5.1(b)(i) approaches full capacity for Manufacturing Product
at its Plant which would be reasonably expected to fail to fulfill Endo’s requirements of Product
within the next [ * ] based on Endo’s most recent forecast, Alexza shall give written notice to
Endo. Within sixty (60) days of receipt of such notice, Endo and Alexza shall meet to determine
courses of action to address such capacity issues. If Endo determines that an appropriate course
of action is establishing an alternative source of supply and Alexza is unwilling or unable to
establish such alternative source of supply, Alexza shall transfer to a Third Party manufacturer
designated by Endo such rights in Alexza Intellectual Property and manufacturing technology and
shall otherwise provide Endo, its Affiliates and such Third Party manufacturer with such support as
may be reasonably necessary to allow for such Third Party to Manufacture in a timely manner in
order to avoid any loss of, or interruption in, supply of Product. Anything herein to the contrary
notwithstanding, in such event (i) Endo may send to such Third Party manufacturer the greater of
the shortage in Alexza’s supply capacity or [ * ] of Endo’s requirements for Product, and (ii) no
royalties shall be payable by Endo to Alexza in respect to Product supplied by such Third Party
manufacturer. For the avoidance of doubt, if Alexza establishes an alternative source of supply by
retaining a Third Party manufacturer as a Subcontractor (at Alexza’s expense), Endo shall owe
Alexza the royalties specified in Section 7.3 in respect to Product supplied by such Third Party
manufacturer.

          (e) Continuing Supply.

               (i) Upon expiration of the Term, at Endo’s request, Alexza shall continue the Manufacture of
Product in accordance with the terms of this Agreement for such period as may be reasonably
necessary for Endo to transfer production to an alternative manufacturer (not to exceed [ * ]),
including, without limitation, time to negotiate terms and qualify and validate any such
alternative manufacturer, and otherwise Manufacture all outstanding orders. Royalties under
Section 7.3 shall be paid by Endo in respect to Product supplied by Alexza during such period,
except that if a Generic Product is then being sold and Alexza provides evidence to Endo that the
royalty does not cover its costs of manufacturing Product (as computed consistent with industry
standards to be direct costs plus a reasonable allocation of indirect labor and facilities costs
attributable to manufacture of Product (but not corporate overhead)) plus [ * ], supply shall be
at such cost of manufacturing plus [ * ].

               (ii) Without limiting the obligations of Alexza set forth elsewhere in this Agreement
regarding Manufacture and technology transfer, commencing at the request of Endo made not earlier
than thirty (30) months prior to the expiration of the Term, Alexza shall transfer rights in Alexza
Intellectual Property and technology to any Third Party manufacturer, and otherwise provide Endo,
its Affiliates and/or any Third Party manufacturer, with such support and technical assistance as
may be reasonably necessary to Manufacture in a timely manner in order to avoid any loss of, or
interruption in, supply of Product. Prior to the expiration of the Term, Endo shall owe Alexza the
royalties specified in Section 7.3 in respect to Product supplied by such Third Party manufacturer
under this Section 5.1(e).

 

			
	[ * ] =	 	  Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

          (f) Long-Term Inability to Supply or Other Inability to Supply. In the event that a Long-Term
Inability to Supply has occurred, Endo shall have the right, at its sole discretion, to (i) use a
Third Party manufacturer and take such other related actions as may be necessary to fill the
Product supply shortfall and not pay Alexza any royalties in respect of Product manufactured by
such Third Party manufacturer; or (ii) exercise any right that Endo may have under Section 14.2(c)
to terminate this Agreement (and all licenses granted to Endo) as a result of such Long-Term
Inability to Supply. In the event that a Long-Term Inability to Supply has occurred, Alexza shall
have the obligation, upon request by Endo, to transfer to the Third Party manufacturer rights in
such Alexza Intellectual Property and technology and otherwise provide Endo, its Affiliates and
such Third Party manufacturer with such support and technical assistance as may be reasonably
necessary to allow the Third Party manufacturer to Manufacture in a timely manner so as to minimize
the loss of, and interruption in, the supply of Product.

          In the event that at any time Alexza is in continuing or repeated breach of its obligations to
supply Product under Section 5, but such breach does not constitute Long-Term Inability to Supply,
in addition to any other remedies Endo may have, Endo may give written notice to Alexza and
thereupon the Parties shall promptly meet to determine courses of action to address such breach.
The Parties shall attempt to agree upon a corrective plan with respect to such breach; provided
that if the Parties are unable to agree upon a corrective plan within ninety (90) days of Endo’s
written notice and if Endo determines that an appropriate course of action is establishing an
alternative source of supply and Alexza is unwilling or unable to promptly establish such
alternative source of supply, then Endo shall notify Alexza of such determination in writing.
Promptly thereafter, Alexza shall transfer to a qualified Third Party manufacturer designated by
Endo such rights in Alexza Intellectual Property and manufacturing technology and shall otherwise
provide Endo, its Affiliates and such Third Party manufacturer with such support as may be
reasonably necessary to allow for such Third Party to Manufacture in a timely manner in order to
avoid any loss of, or interruption in, supply of Product. Anything herein to the contrary
notwithstanding, in such event (i) Endo may send to such Third Party manufacturer the greater of
the shortage in Alexza’s supply capacity or [ * ] of Endo’s requirements for Product, and (ii) no
royalties shall be payable by Endo to Alexza in respect to Product supplied by such Third Party
manufacturer. For the avoidance of doubt, if Alexza establishes an alternative source of supply by
retaining a Third Party manufacturer as a Subcontractor (at Alexza’s expense), Endo shall owe
Alexza the royalties specified in Section 7.3 in respect to Product supplied by such Third Party
manufacturer.

          (g) Commercial Supply. Not less than [ * ] prior to the initiation of the first Phase III
clinical study of a Product, the Parties shall agree upon Specifications for the Product and amend
the Quality Agreement consistent with Alexza’s obligations to Manufacture Product for commercial
sale.

ARTICLE 6

COMMERCIALIZATION

     6.1 Commercialization. Endo shall have sole responsibility and decision-making authority for
commercialization of Product in the U.S. (and if Regulatory Approval for a Product

been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

is pursued by Endo as provided in Section 4.1(a) and obtained, elsewhere in the Territory
where such Regulatory Approval is obtained), which shall be carried out in accordance with the
Commercialization Plan. Endo shall be solely responsible for all costs and expenses associated
with its commercialization of Product in the Territory. Endo may, in its sole discretion, choose
whether to market and sell a particular Product itself or to collaborate with Affiliates,
sublicensees or distributors to market and sell such Product, subject to Section 8.6.

     6.2 Commercialization Plan.

          (a) No later than [ * ] prior to the anticipated filing of an application for Regulatory
Approval for a Product in the U.S., Endo shall deliver to the JSC a draft written commercialization
plan setting forth anticipated material commercialization activities to be performed with respect
to such Product in the U.S. by Endo or on its behalf, as well as projected timelines for such
activities (the “Commercialization Plan”). The JSC shall promptly review such draft initial
Commercialization Plan and may provide commercially reasonable comments to Endo for its
consideration. Endo shall give good faith consideration to such comments and may revise such draft
Commercialization Plan to implement such of the JSC’s comments that it shall deem necessary or
advisable to include in the draft. Endo shall, thereafter, submit the Commercialization Plan with
such changes, revisions and modifications that it shall deem advisable to the JSC, and the
Commercialization Plan, together with such changes, revisions and modifications, as applicable,
shall be deemed final.

     
     (b) No later than [ * ] prior to the anticipated launch of a Product in the U.S., Endo shall
update the Commercialization Plan, and shall thereafter update the Commercialization Plan on an
annual basis as follows: Endo shall provide the JSC with a draft update to the Commercialization
Plan no later than December 1 of each year. Endo shall give good faith consideration to any
comments provided by the JSC and may revise such Commercialization Plan to implement such of the
JSC’s comments that it shall deem necessary or advisable to include in the Commercialization Plan,
after which the update to the Commercialization Plan shall be deemed to be finalized. Endo shall
deliver a final version of the updated Commercialization Plan no later than January 31 of the
following year.

          (c) The Commercialization Plan shall include a marketing plan for the Product for which
Regulatory Approval is being sought or obtained in the U.S. that includes plans related to the
anticipated promotion and sale of such Product in the U.S., competitive analysis, including
information regarding actions intended to mitigate competitive threats, a non-binding sales
forecast for the following year and the marketing, promotion and advertising campaigns proposed to
be conducted, including the number of detailing representatives, level of promotion and Endo’s
medical education activities.

     6.3 Efforts. Endo shall use Commercially Reasonable Efforts to commercialize each Product in
such part of the Territory for which Regulatory Approval is obtained. If Alexza in its reasonable
opinion believes that Endo has not satisfied any of its material obligations under this Section,
Alexza may convene a special meeting of the JSC to discuss the matter by written notice to Endo.
Such notice shall state with particularity the obligations that Alexza believes that Endo has not
satisfied and the basis for such belief, including any supporting evidence that it wishes to

 

			
	[ * ] =	 	  Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

provide in connection therewith. The meeting shall be convened at Endo’s office in Chadds
Ford, Pennsylvania, within ten (10) Business Days of Endo’s receipt of such notice. At such
meeting, the members of the JSC shall discuss the concerns of Alexza, Endo’s efforts in such areas
of concern and any additional actions that Alexza requests that Endo take to remedy the cause for
Alexza’s concern. If after such meeting Alexza continues to have reasonable belief that Endo is
not meeting its obligations under this Section, Alexza may within one hundred eighty (180) days
after such meeting so notify Endo in writing. Within thirty (30) days after the date of any such
notice, Endo shall respond in writing in good faith to Alexza with its explanation and supporting
evidence. The foregoing procedure is not intended to limit Alexza’s right to terminate this
Agreement under Section 14.2(c) with respect to any failure by Endo to comply with the first
sentence of this Section 6.3 that is a material breach of this Agreement.

ARTICLE 7

PAYMENTS

     7.1 Upfront Payment. Endo shall pay Alexza a nonrefundable, non-creditable payment of Ten
Million Dollars ($10,000,000) within five (5) Business Days after the Effective Date.

     7.2 Milestone Payments. Endo shall make the following nonrefundable, non-creditable payments

below:

          (a) [ * ];

          (b) [ * ];

          (c) [ * ]; and

          (d) [ * ].

     As a matter of clarification, the payments referred to in subsections (a), (b), and (c) above
shall be made one time with respect to the first Product which meets the requirements for the
payment and not for any subsequent Product and the payment referred to in subsection (d) shall be
made the first time the corresponding event is achieved and not for any subsequent achievement of
such event.

     7.3 Royalty Payments. Commencing with the First Commercial Sale of the Initial Product, Endo
shall make royalty payments to Alexza equal to [ * ] of [ * ] of such Product, except that if a
Generic Product is sold by a Third Party within a country in the Territory during the Term, the
royalties to which Alexza is entitled hereunder with respect to sales in such country shall be
reduced by [ * ]. All royalties due under this Section 7.3 shall be paid quarterly within sixty
(60) days of the end of the relevant calendar quarter. Endo shall be permitted to credit against
such royalty payment the transfer price specified in Section 5.1(c)(vi) that is paid by Endo for
the units of Product whose sale gave rise to such royalties, it being understood that a transfer
price shall only be payable for Product during the [ * ].

 

			
	[ * ] =	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

 Any transfer price
payments not credited against royalties for any period shall be carried forward and applied to
subsequent royalty payments.

     7.4 Term of Royalties. Alexza’s right to receive royalties under Section 7.3 shall expire on
a Product-by-Product basis upon the later of (a) [ * ] years from the First Commercial Sale of such
Product in the Territory, or (b) the expiration of the last to expire Alexza Patent in the
Territory.

     7.5 Royalty Reports. Commencing with the First Commercial Sale of a Product in the Territory,
Endo shall provide Alexza with a written report together with the royalty payment within forty five
(45) days after the last day of each calendar quarter. Each such report shall include a
calculation of the Net Sales of Product, on a Product-by-Product basis made during the calendar
quarter in question, the royalties payable thereon and the total annual Net Sales for the year to
date. In addition, Endo shall provide Alexza within thirty (30) days after the last day of each
calendar quarter with its then-current estimate of the royalties payable by Alexza for the prior
quarter.

     7.6 Payment Method. All payments due under this Agreement to Alexza shall be made by bank
wire transfer in immediately available funds to an account designated by Alexza. All payments
hereunder shall be made in U.S. dollars.

     7.7 Taxes. Alexza shall pay any and all taxes levied on account of all payments it receives
under this Agreement. If laws or regulations require that taxes be withheld, Endo will (a) deduct
those taxes from the remittable payment, (b) pay the taxes to the proper taxing authority, and (c)
send evidence of the obligation together with proof of tax payment to Alexza within thirty (30)
days following that tax payment.

     7.8 Interest. If either Party fails to make any payment due under this Agreement within ten
(10) Business Days after the date upon which such payment is due, then interest shall accrue on
such payment on a daily basis from the date such payment was originally due at a rate equal to [ *
] above the then-applicable prime commercial lending rate of Citibank, N.A., or at the maximum rate
permitted by applicable law, whichever is the lower, and such interest shall be paid when such
payment is made.

     7.9 Records.

          (a) Retention. Endo shall keep for at least three (3) years following the end of the calendar
year to which they pertain complete records of External PC&R Costs and of the Net Sales of Product
in the Territory. Such record keeping obligation shall survive any expiration or termination of
this Agreement for the time provided herein.

          (b) Access to Records. Subject to the other terms of this Section 7.9, Alexza may audit the
records of Endo regarding External PC&R Costs and Net Sales. Such audit shall be conducted (i)
after at least thirty (30) days prior written notice from Alexza, (ii) at the facility(ies) where
the applicable records are maintained, (iii) with the minimal reasonable

 

			
	[ * ] =	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

disruption to operations of Endo (to the extent reasonably practicable, such examination shall
be completed within ten (10) Business Days), (iv) no more frequently than once in any calendar
year, and (v) with respect to calendar years ended not more than two (2) years prior to the date of
the audit. The audit shall be conducted by a nationally recognized independent certified public
accountant selected by Alexza (but not the accountant that conducts or has within the past three
(3) years conducted the audit of Alexza’s financial statements). The auditor will execute a written
confidentiality agreement with Endo that is substantially similar to the confidentiality provisions
of Article 10 and limiting the disclosure and use of information obtained from such audit to
authorized representatives of the Parties and the purposes germane to this Section 7.9. The
auditor will disclose to Alexza only the amount and accuracy of costs or payments, as applicable,
reported and actually paid or otherwise payable under this Agreement. The auditor will send a copy
of the report to both Parties at the same time. Alexza shall be responsible for expenses for the
independent certified public accountant, except that Endo shall reimburse Alexza up to [ * ] for
such independent accountant documented services if the independent accountant determines that the
costs reported or payments made by Endo are less than [ * ] of the amount actually owed in the case
of payments, or more than [ * ] in excess of actual costs in the case of cost reporting, in each
case for the period of the audit and such determination is finally resolved in favor of Alexza
pursuant to Section 7.9(d) below if contested by Endo.

          (c) Underpayment or Overpayment. If, as a result of any audit pursuant to Section 7.9(b), it
is shown that Endo’s charges to Alexza for External PC&R Costs with respect to the time period
audited were higher than the amount that should have been charged or that Endo’s payments to
Alexza under this Agreement with respect to the period of time audited were less than the amount
that should have been paid pursuant to this Agreement, then Endo shall, within thirty (30) days
after Alexza’s demand therefor, either pay Alexza the amount of such excess charge or shortfall in
payment, plus interest thereon as provided in Section 7.8, or proceed to the dispute resolution
mechanism set forth in Section 7.9(d) below. If, as a result of any audit pursuant to Section
7.9(b), it is shown that Endo’s charges to Alexza for External PC&R Costs with respect to the time
period audited were less than the amount that should have been charged or that Endo’s payments to
Alexza under this Agreement with respect to the period of time audited exceeded the amount that
should have been paid pursuant to this Agreement, then Alexza shall, within thirty (30) days after
Endo’s demand therefor, either pay Endo the amount of such under charge or excess, plus interest
thereon as provided in Section 7.8, or proceed to the dispute resolution mechanism set forth in
Section 7.9(d) below.

          (d) Resolution of Dispute as to Audit. In the event that the Parties do not agree on the
amount of overpayment or underpayment, within thirty (30) days, each Party shall select an
independent public accounting firm (and each Party shall pay the costs of its own accounting firm),
which shall meet and discuss the amount in dispute and other related matters within thirty (30)
days thereafter. If such independent public accounting firms cannot agree on a resolution mutually
agreeable to the Parties, such independent public accounting firms shall, within thirty (30) days
after such selection, appoint a third independent public accounting firm which shall resolve the
issue within thirty (30) days after its selection, and the Parties shall equally share the costs of
such accounting firm. The recommendation of the third independent public accounting firm shall be
final and binding upon the Parties. A judgment on such firm’s disposition may be entered in any
court having jurisdiction over the Parties. Notwithstanding

anything to the contrary herein, the resolution of any dispute under this Section 7.9 shall be made
under this subsection 7.9(d) instead and in lieu of Section 15.11. The preceding sentence shall
not preclude the application of Section 15.11 to any contract interpretation issue (as compared to
an accounting issue which would be precluded from determination under Section 15.11).

under Endo Intellectual Property, to use and practice Endo Intellectual Property in connection with
the manufacture, development and commercialization of Product outside the Territory so long as any
licensee of Alexza outside the Territory grants to Alexza (with right to sublicense to Endo)
intellectual property developed by such licensee in connection with development and
commercialization of Product outside the Territory for use and practice of such licensee’s
intellectual property in connection with the manufacture, development and commercialization of

     8.4 Alexza Trademarks.

          (a) Grant of License. Subject to the terms and conditions of this Agreement, Alexza hereby
grants to Endo an exclusive, royalty-bearing (such royalties that are payable being specified in
Section 7.3 for the period specified in Section 7.4) license (with the right to sublicense in
accordance with Section 8.6) to use the Alexza Trademarks specified on Exhibit C solely in
connection with Pre-Clinical Trials and Clinical Trials and upon, or in relation to, Product. Endo
agrees that it shall use Commercially Reasonable Efforts to use the Alexza Trademarks on Product
and identify Alexza as the manufacturer of Product on the packaging therefor, subject, in all
respects, to all applicable laws and Regulatory Requirements. Nothing in this Agreement shall
obligate Endo to identify a Product, or to use Alexza’s Trademarks with respect to a Product, in
any manner that Endo, in its reasonable discretion, determines may have an adverse effect upon the
development or marketability of, or potential sales with respect to, such Product.

          (b) Use of Trademarks. Endo agrees to comply with all applicable laws and regulations
pertaining to the proper use and designation of the Alexza Trademarks. Additionally, Endo shall
use Commercially Reasonable Efforts to:

               (i) use the Alexza Trademarks upon or in relation to Product only in such manner that
the
distinctiveness, reputation, and validity of the Alexza Trademarks shall not be impaired, and

by words accurately describing the nature of the goods or services to which it relates and that the
Alexza Trademarks are displayed as set forth in Exhibit C;

               (ii) comply with the reasonable requirements of Alexza, to the extent provided by Alexza
to
Endo in writing, as to the form, manner, scale and context of use of the Alexza Trademarks;

               (iii) display the proper form of trademark and service mark notice associated with each
Alexza
Trademark in accordance with instructions received from Alexza, subject to Endo being responsible
in this regard to use only the same degree of care as Endo uses with its own marks;

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

               (iv) include, on any item which bears a Alexza Trademark, a statement identifying Alexza
as
the owner of such Alexza Trademark and stating that Endo is an authorized user of such Alexza
Trademark;

               (v) not conduct, without the written consent of Alexza, the whole or any part of its
business
under a business name or trading style which incorporates any of the Alexza Trademarks; and

               (vi) neither use nor display any of the Alexza Trademarks in such relation to any other
mark
or marks owned by any Third Party, Endo or an Affiliate of Endo as to suggest that the multiple
marks constitute a single or composite trademark, service mark, or are under the same
proprietorship.

          (c) Additional Trademark Terms. Endo shall not take any action inconsistent with Alexza’s
ownership of the Alexza Trademarks. Any benefits (including good will) accruing from Endo’s use of
the Alexza Trademarks shall automatically vest in Alexza. Endo shall not form any combination
trademarks or trade names with the Alexza Trademarks. Endo shall grant Alexza reasonable access to
Endo’s packaging and promotional materials for the purpose of inspecting Endo’s use of the Alexza
Trademarks.

     8.5 Negative Covenants.

          (a) Endo hereby covenants that it shall not use or practice, nor shall it cause or permit any
of its Affiliates or sublicensees to use or practice, directly or indirectly, any Alexza
Intellectual Property or Alexza Trademarks for any other purposes other than those expressly
permitted by this Agreement.

          (b) Alexza hereby covenants that it shall not use or practice, nor shall it cause or permit
any of its Affiliates or sublicensees to use or practice, directly or indirectly, any Endo
Intellectual Property, Endo Product Patents or Endo Know-How for any other purposes other than
those expressly permitted by this Agreement.

     8.6 Rights to Sublicense. Subject to Section 8.1(c)(i), Endo shall have the right to
sublicense the rights granted under Sections 8.1 and 8.4 to any Affiliate of Endo and to any Third
Party in Mexico and Canada without the prior written consent of Alexza, and to any Third Party in
the U.S. only with the prior written consent of Alexza, such consent not to be unreasonably
withheld. In the event that Endo sublicenses the rights granted under Sections 8.1 and 8.4, Endo
shall provide Alexza with an accurate and complete copy of the applicable sublicense agreement no
later than thirty (30) days after execution of such sublicense agreement.

     8.7 No Implied Licenses. Neither Party grants (or agrees to grant) to the other Party any
right or license to use any of its intellectual property, know-how or other proprietary
information, materials or technology, or to practice any of its patent, trademark, or trade dress
rights, except as expressly set forth in this Agreement.

ARTICLE 9

INTELLECTUAL PROPERTY

     9.1 Background Intellectual Property. Except as expressly set forth herein, as between the
Parties, each Party is and shall remain the owner of all intellectual property and Confidential
Information that it owns or controls as of the Effective Date or that it develops or acquires
thereafter pursuant to activities independent of this Agreement.

     9.2 Ownership of Developed Technology. Each Party shall own and retain the entire right,
title and interest in and to all Developed Technology made solely by the employee(s) or agent(s) of
such Party or any of its Affiliates, subject only to the rights expressly granted to the other
Party under this Agreement. Each Party shall own and retain an undivided equal ownership interest
in all Developed Technology made jointly by the employee(s) or agent(s) of one Party or any of its
Affiliates and the employee(s) or agent(s) of the other Party or any of its Affiliates, subject
only to the rights expressly granted by the Parties under this Agreement. Inventorship of
Developed Technology will be determined in accordance with U.S. laws of inventorship. Each Party
hereby assigns and agrees to assign to the other Party such rights in the Developed Technology, and
to take all other actions, in each case that are reasonably necessary to give effect to the
ownership interests set forth in this Section 9.2.

     9.3 Patent Prosecution and Maintenance. Except as provided below and in Section 9.4, Alexza
shall have the sole right to prosecute and maintain the Alexza Patents in the Territory, to the
extent it has the rights to do so. Alexza shall provide Endo with a reasonable opportunity to
comment on all draft filings for the Alexza Patents in the Territory listed on Schedule 1.6
(including, without limitation, any foreign counterparts in the Territory, continuations,
divisions, or continuations-in-part, and any substitution, reissue, renewal, reexamination,
protection certificate, extension, registration or confirmation patent), prior to their submission
to the relevant patent authority. On the reasonable request of Alexza, Endo shall cooperate, in
all reasonable ways, in connection with the prosecution of the Alexza Patents. Should Alexza
decide that it is no longer interested in maintaining or prosecuting a particular Alexza Patent in
the Territory, it shall promptly advise Endo, and Endo may assume such prosecution and maintenance
in the Territory at its sole expense.

     9.4 Infringement by Third Parties.

          (a) Notice. Each of Endo and Alexza shall promptly notify the other Party in writing of any
alleged or threatened infringement of any Alexza Patent by a Third Party product that delivers the
Drug through inhalation (a “Field Infringement”), of which the Party becomes aware.

          (b) Right to Bring Suit. Endo shall have the first right to bring and control any action or
proceeding with respect to any Field Infringement. If Endo does not bring and continue pursuing an
action or proceeding against, or otherwise cause the cessation of Field Infringement by or after
(i) one hundred twenty (120) days following the notice of alleged infringement or (ii) ten (10)
days before the time limit, if any, set forth in the appropriate laws and regulations for the
filing of such an action, whichever comes first, then Alexza shall have the

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

right to bring and control an infringement action under the applicable Alexza Patents with
respect to such Field Infringement at its own expense and by counsel of its own choice.

          (c) Cooperation; Settlement. For any action or proceeding brought by a Party under this
Section 9.4 (the “Initiating Party”), regardless of which Party brings such action or proceeding,
the other Party (the “Non-Initiating Party”) hereby agrees to cooperate reasonably in any such
effort, all at the Initiating Party’s expense, and the Parties shall reasonably cooperate to
address new facts or circumstances that come to light during the course of any such action or
proceeding that may affect the need for one Party or the other to participate in such action. The
Non-Initiating Party agrees to be joined as a party plaintiff, at the Initiating Party’s expense,
in any such action if needed for the Initiating Party to bring or continue an infringement action
hereunder. The Non-Initiating Party shall, at its own expense and with its own counsel, have the
right to advise and provide comments with respect to any action against a Field Infringement
brought by the Initiating Party under this Section 9.4. Neither Party may settle any action or
proceeding brought against a Field Infringement under this Section 9.4 in a manner that, or take
any other action in the course thereof that, to the knowledge of the Party taking the action,
materially adversely affects the other Party’s interest in the Alexza Patents, without the written
consent of such other Party, such consent not to be unreasonably withheld.

          (d) Recoveries. Except as otherwise agreed to by the Parties as part of a cost-sharing
arrangement, any recovery realized as a result of any litigation under this Section 9.4, after
reimbursement of any litigation expenses of Endo and Alexza, as applicable, shall be retained by
the Party that brought and controlled such litigation for purposes of this Agreement; provided,
however, that, the other Party shall be entitled to receive twenty-five percent (25%) of any
recovery realized by the Party that brought and controlled such litigation under this Section 9.4,
after reimbursement of each of the Parties’ related litigation expenses.

          (e) Other Infringements. Notwithstanding anything to the contrary in this Agreement, Alexza
shall have the sole right to bring and control any action or proceeding with respect to any alleged
or threatened infringement of any Alexza Patent other than a Field Infringement, and Alexza shall
retain any recovery realized by Alexza in connection therewith.

     9.5 Third Party Claims for Infringement or Misappropriation. Each Party shall promptly notify
the other in writing of any potential or actual allegation, claim or suit that the manufacture, use
or sale of a Product, the Drug, the Device contained in a Product or any component thereof, or any
other activities that are undertaken pursuant to this Agreement, infringes or misappropriates a
Third Party’s patent or other proprietary rights. To the extent such potential or actual
allegation, claim or suit relates to the Device contained in the Product (and does not relate to
the use or combination of such Device with goods, materials, or services not supplied by Alexza, or
any modification or alteration of such Device by anyone other than Alexza, where the alleged
infringement or misappropriation would not have arisen except for such use, combination,
modification or alteration), Alexza shall have the sole right to obtain a license from such Third
Party and shall bear all costs associated therewith and shall use Commercially Reasonable Efforts
to obtain such a license. If such potential or actual allegation, claim or suit is not addressed
in the preceding sentence, then the Parties shall determine as soon as practicable thereafter
whether it is reasonably necessary or appropriate to obtain a license

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

from such Third Party, which Party shall seek to so obtain such license and how the costs
associated with such license shall be allocated between the Parties.

ARTICLE 10

CONFIDENTIALITY

     10.1 Definition of Confidential Information. During the Term, either Party (the “Disclosing
Party”) may from time to time furnish the other Party (the “Receiving Party”) with scientific,
technical, trade or business information or materials which are treated by the Disclosing Party as
confidential or proprietary, including, without limitation, information and materials related to
the Drug, the Device, Product, processes, methods for pulmonary delivery of drugs, assay systems,
formulae, procedures, tests, equipment, data, batch records, reports, know-how, sources of supply,
patent positioning, relationships with consultants and employees, business plans and business
developments, and information concerning the existence, scope or activities of any research,
design, development, manufacturing, marketing or other projects. All such disclosed information
shall be referred to herein as “Confidential Information” if it is provided in writing and is
designated or otherwise identified as “Confidential” at the time of disclosure, or if is first
provided orally, visually, or by inspection and is identified as “Confidential” at the time of
disclosure. Notwithstanding the foregoing, Confidential Information shall also include such
information or materials that would reasonably be identified or understood by the Receiving Party
to be the confidential or proprietary information of the Disclosing Party, even if they are not so
identified as described in the previous sentence. The “Alexza Confidential Information” means any
and all Confidential Information for which Alexza is the Disclosing Party and Endo the Receiving
Party hereunder. The “Endo Confidential Information” means any and all Confidential Information for
which Endo is the Disclosing Party and Alexza the Receiving Party hereunder.

     10.2 Confidentiality. Except to the extent expressly authorized by this Agreement or
otherwise agreed in writing by the Parties, the Parties agree that for the Term and for seven (7)
years thereafter, the Receiving Party shall keep confidential and shall not publish or otherwise
disclose and shall not use for any purpose any Confidential Information furnished to it by the
Disclosing Party pursuant to this Agreement.

     10.3 Exclusions. Notwithstanding anything herein to the contrary, the obligations of
confidentiality and nonuse under this Article 10 applicable to Confidential Information hereunder
shall not apply to information that:

          (a) at the time of disclosure, is known publicly or thereafter becomes known publicly through
no fault of the Receiving Party, its Affiliates or agents;

          (b) is disclosed to the Receiving Party on a non-confidential basis by a Third Party that is
not legally prohibited from disclosing such information;

          (c) was developed by the Receiving Party independently of information obtained from the
Disclosing Party, as shown by the Receiving Party’s prior written records;

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

          (d) was already known to the Receiving Party before receipt from the Disclosing Party, as
shown by the Receiving Party’s prior written records; or

          (e) is released with the prior written consent of the Disclosing Party.

     10.4 Permitted Disclosures. Notwithstanding the foregoing, each Receiving Party may disclose
the Disclosing Party’s Confidential Information (a) to the Receiving Party’s employees,
consultants, Affiliates, agents, contractors, or sublicensees who are bound by obligations relating
to confidentiality at least as restrictive of those contained herein and who have a need to know
such information in connection with the Receiving Party’s performance of its obligations or
practice of its rights under this Agreement, (b) to Regulatory Authorities in connection with any
Regulatory Submissions required for development of Product pursuant to the Development Plan or in
compliance with Regulatory Requirements, including, without limitation, any requirements under or
pursuant to the Food and Drug Administration Amendments Act of 2007, (c) if Alexza is the Receiving
Party, to Regulatory Authorities in connection with any Regulatory Submissions in connection with
Alexza’s exercise of its rights under Section 4.1(e) and Section 8.2, or (d) pursuant to Section
10.6.

     10.5 Terms of Agreement. Subject to Section 10.6 below, no Party shall, without the prior
written consent of the other Party, disclose in any manner to any Third Party the material terms
and conditions of this Agreement, except for terms or subject matter which has been the subject of
prior public disclosure or has been mutually approved for such disclosure. Notwithstanding the
foregoing, each Party shall have the right to disclose the material terms of this Agreement in
confidence to any bona fide potential or actual investor, investment banker, counsel, acquirer,
merger or acquisition target or sublicensee that is otherwise bound by obligations of
confidentiality at least as restrictive as those contained in this Agreement.

     10.6 Mandatory Disclosure.

          (a) Notification and Consultation. In the event that the Receiving Party is required by
applicable statute, regulation, or stock exchange rules or by court order or judicial or
administrative process to disclose any part of the Disclosing Party’s Confidential Information or
any material terms or conditions of this Agreement, the Receiving Party shall (i) promptly notify
the Disclosing Party of each such requirement and identify the documents so required thereby, so
that the Disclosing Party may seek or request the Receiving Party to seek an appropriate protective
order, confidential treatment or other remedy and/or waive compliance by the Receiving Party with
the provisions of this Agreement and (ii) consult with the Disclosing Party on the advisability of
taking legally available steps to resist or narrow the scope of such requirement. Each Party
acknowledges that the other Party may be legally required to file this Agreement as an exhibit to
its filings with the U.S. Securities and Exchange Commission.

          (b) Limited Disclosure. If, in the absence of such a protective order, confidential treatment
request, other remedy or waiver by the Disclosing Party, the Receiving Party is nonetheless
required to disclose any part of the Disclosing Party’s Confidential Information or any material
terms or conditions of this Agreement, the Receiving Party may disclose such Confidential
Information or material terms or conditions without liability under

this Agreement, except that the Receiving Party shall furnish only that portion of the
Confidential Information or material terms or conditions that is legally required.

Agreement shall be substantially in the form of the press release attached as Exhibit D, and the
Parties will cooperate in the release thereof as soon as practicable after the signature of this
Agreement by the Parties. No Party shall publish or otherwise disclose any other press release,
publicity or other form of public written disclosure announcing, describing, or referring to this
Agreement unless the other Party has provided its written consent, which consent shall not be
unreasonably withheld. Each Party shall review any such press release, publicity, or other form of
public disclosure within three (3) Business Days of having received it or within such other time as
may be agreed by the Parties. Notwithstanding the foregoing, if a Party is making such a press
release, publicity or other form of public disclosure to fulfill its applicable regulatory
reporting or legal disclosure obligations, this Section 11.1 shall not apply, but the provisions of
Section 10.6 shall apply instead.

     11.2 Use of Names. Alexza shall not make use of the name of Endo or any of its Affiliates in
any advertising or promotional material, or otherwise, without the prior written consent of Endo
except pursuant to Section 11.1. Except as provided in Section 8.4 or 11.1, Endo shall not make
use of the name of Alexza or any of its Affiliates in any advertising or promotional material, or
otherwise, without the prior written consent of Alexza. Notwithstanding the foregoing, either
Party may use the name of the other Party or its Affiliates in the context of mentioning the
existence of this Agreement in advertising or promotional materials.

     11.3 Publication.

          (a) Prior to public disclosure or submission for publication of a proposed publication
describing the results of any scientific or clinical activity relating to Product, each Party shall
send the JSC by expedited delivery a copy of the proposed publication to be submitted and the JSC
shall have a reasonable time period (but no less than thirty (30) days from the date of confirmed
receipt) in which to determine whether the proposed publication contains subject matter for which
patent protection should be sought (prior to publication of such proposed publication) for the
purpose of protecting an invention, or whether the proposed publication contains Confidential
Information of the other Party, or whether the proposed publication contains information that is
reasonably likely to have a material adverse impact on the development or commercialization of the
Device or the Staccato Technology or Product. Following the expiration of the applicable time
period for review, the applicable Party shall be free to submit such proposed publication for
publication and publish or otherwise disclose to the public such scientific or clinical results,
subject to the procedures set forth in Section 11.3(b), except that any publication in the
Territory by or on behalf of Alexza, its Affiliates, sublicensees or Subcontractors requires the
prior written consent of Endo, not to be unreasonably withheld.

          (b) If the JSC believes that the subject matter of the proposed publication contains
Confidential Information of the non-publishing Party or a patentable invention owned by such Party
or in which such Party otherwise has rights, then prior to the expiration of the applicable time
period for review, the JSC shall notify the other Party in writing of such belief. On receipt of
written notice from the JSC that such proposed publication contains Confidential Information of the
non-publishing Party, the publishing Party shall remove such Confidential Information from such
proposed publication prior to any publication thereof, unless the non-publishing Party agrees
otherwise in writing. On receipt of written notice from the JSC that such proposed publication
contains a patentable invention owned by the non-publishing Party or in which the non-publishing
Party otherwise has rights, the publishing Party shall delay public disclosure of such information
or submission of the proposed publication for an additional period of thirty (30) days to permit
preparation and filing of a patent application on such invention. The publishing Party shall
thereafter be free to publish or disclose such information, subject to Article 10 and the last
sentence in Section 11.3(a).

ARTICLE 12

REPRESENTATIONS AND WARRANTIES

     12.1 Mutual Representations and Warranties of Alexza and Endo. Each of Alexza and Endo hereby
represents and warrants to the other Party as of the Effective Date as follows:

          (a) It is duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. It has the requisite corporate power and authority to conduct
its business as presently being conducted and as proposed to be conducted by it.

          (b) It has the requisite corporate power and authority to enter into this Agreement and to
perform the services contemplated hereunder. All corporate actions on its part, necessary for (i)
the authorization, execution, delivery and performance by it of this Agreement, and (ii) the
consummation of the transactions contemplated hereby, have been duly taken.

          (c) Assuming the due authorization, execution and delivery by the other Party, this Agreement
is its legally valid and binding obligation, enforceable against it in accordance with its terms
(except in all cases as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting the enforcement of creditors’ rights
generally and except that the availability of the equitable remedy of specific performance or
injunctive relief is subject to the discretion of the court or other tribunal before which any
proceeding may be brought).

          (d) There is no contractual restriction or obligation binding on either Party which would be
materially contravened by execution and delivery of this Agreement or by the performance or
observance of its terms.

          (e) Each Party has and will continue to have written contracts with all Third Parties
(including employees and subcontractors) performing services on its behalf under this

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

Agreement where such services are intended to create inventions that assign or license to such
Party all inventions and rights therein.

          (f) To each Party’s knowledge, no representation or warranty made by it in this Agreement, nor
any statement contained in any schedule or exhibit hereto furnished by it, contains any untrue
statement of a material fact or omits any material fact necessary to make the statements contained
herein or therein not misleading.

     12.2 Additional Representations and Warranties of Alexza. Alexza hereby further represents
and warrants to Endo as of the Effective Date:

          (a) Alexza is the owner of, or has exclusive rights to, all of the Alexza Patents in
existence on the Effective Date and is the owner of all of the Alexza Know-How in existence on the
Effective Date and has not granted rights in any of the Alexza Know-How to any Third Party (other
than licenses granted to Symphony Allegro and its affiliated entities (collectively, “Symphony”)
with respect to certain products that are not Products). The Alexza Patents are in full force and
effect. Alexza has the exclusive right to grant the rights granted under this Agreement. To the
knowledge of Alexza, all of the issued Alexza Patents in existence on the Effective Date are valid
and enforceable.

          (b) All of the information requested by Endo for due diligence purposes in connection with
entering into this Agreement has been provided by Alexza and all of such information is in all
material respects true, complete and unredacted (except as expressly noted). Without limiting the
generality of the foregoing, Alexza has provided Endo, or given Endo access to true, complete and
unredacted (except as expressly noted) copies of all (i) submissions to, and correspondence with,
Regulatory Authorities relating to the Device, Drug or Product, including adverse event files,
complaint files, manufacturing records and inspection reports; and (ii) material agreements
(including any letter agreements) between Alexza and any licensor, licensee, production or
financing partner or other Third Party, including all effective amendments to any such agreements,
which in any event (A) would reasonably be expected to materially affect Endo’s rights under the
Agreement; or (B) relates to the Device, Drug or Product. Alexza is in material compliance with
all applicable federal, state and local laws, rules and regulations, including, without limitation,
all Regulatory Requirements, with respect to each facility and site to be used in the Manufacture
of Product and, to Alexza’s knowledge, there are no circumstances or conditions which would
reasonably be expected to prevent compliance from continuing during the duration of this Agreement
or to interfere with Alexza’s ability to Manufacture Product as required by this Agreement.

          (c) There is no pending or, to the knowledge of Alexza, threatened claim, interference,
opposition or demand of any Third Party challenging the ownership, validity or scope of any Alexza
Intellectual Property or Alexza Trademarks in existence as of the Effective Date. To the knowledge
of Alexza, (i) the manufacture or sale of the Initial Product (as formulated as of the Effective
Date) or its use in each indication included in the Initial Indication will not infringe any
existing issued patent in the Territory and (ii) in developing or acquiring the Alexza Intellectual
Property or Alexza Trademarks, Alexza has not misappropriated any trade secret of any Third Party.

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

          (d) Alexza has disclosed to Endo its current financing arrangement with Symphony (as defined
in Section 12.2(a)), pursuant to which certain of the Alexza Intellectual Property is exclusively
licensed to Symphony with respect to certain products that are not Products and certain of such
Alexza Intellectual Property is exclusively sublicensed by Symphony to Alexza. To the knowledge of
Alexza, except as set forth in the Alexza’s agreements with Symphony in connection with such
financing arrangement, there are no liens or claims currently existing on or to the Alexza
Intellectual Property or Alexza Trademarks or on any proceeds thereof (including any liens or
claims on or to (i) rights to sue for past, present and future infringements thereof, (ii) any
licenses, claims, damages and proceeds of suit arising therefor, or (iii) any payments or rights to
payments arising out of the sale, lease, license, assignment, or other disposition thereof). No
liens or claims currently exist on or to Alexza Intellectual Property or Alexza Trademarks or
proceeds thereof, and Alexza will not create, incur, or permit to exist on or to any Alexza
Intellectual Property or Alexza Trademarks or proceeds thereof any lien or claim, in each case that
could adversely affect in any material respect any rights of Endo under this Agreement, including
any right of set-off or credit.

          (e) Product supplied to Endo will be of satisfactory quality, free of any defects and will be
Manufactured in compliance with the Specifications, cGMP and all other provisions of this
Agreement, the Quality Agreement and all applicable federal, state and local laws, rules and
regulations, including, without limitation, all Regulatory Requirements and environmental laws, in
force at the time of Manufacture.

     12.3 Disclaimer. EXCEPT AS EXPRESSLY PROVIDED IN THIS ARTICLE 12, EACH PARTY DISCLAIMS ANY
AND ALL WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE WARRANTIES OF
DESIGN, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT OF THE INTELLECTUAL

Alexza, its Affiliates, and their respective directors, officers, employees consultants,
contractors, sublicensees and agents (collectively, the “Alexza Indemnitees”) harmless from and
against any and all claims, suits, proceedings or causes of action (“Claims”) brought by a Third
Party against such Alexza Indemnitee, including any damages or other amounts payable to such Third
Party, as well as any reasonable attorneys’ fees and costs of litigation incurred as to any such
Claim until the indemnifying Party has acknowledged that it will provide indemnification hereunder
with respect to such Claim as provided below (collectively, “Damages”), in each case resulting from
or based on: (a) clinical development, use, importation, offer for sale or sale of any Product in
the Territory, (b) Endo’s breach of this Agreement; (c) the negligence or willful misconduct of, or
violation of applicable law by, Endo,

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

its Affiliates or (sub)licensees, or their respective employees, contractors or agents in the
performance of this Agreement; and/or (d) breach of a contractual or fiduciary obligation owed by
Endo to a Third Party (including without limitation misappropriation of trade secrets). The
foregoing indemnity obligation shall not apply to the extent Alexza has an obligation to indemnify
Endo in respect to such matter under Section 13.2.

     13.2 Indemnification by Alexza. Subject to Section 13.3, Alexza shall indemnify, defend and
hold Endo, its Affiliates, and their respective directors, officers, employees consultants,
contractors, sublicensees and agents (collectively, the “Endo Indemnitees”) harmless from and
against any and all Claims brought by a Third Party against such Endo Indemnitee, including any
Damages resulting therefrom, in each case resulting from or based on: (a) Alexza’s breach of this
Agreement; (b) the negligence or willful misconduct of, or violation of applicable law by, Alexza,
its Affiliates or (sub)licensees, or their respective employees, contractors or agents in the
performance of this Agreement; (c) breach of a contractual or fiduciary obligation owed by Alexza
to a Third Party (including without limitation misappropriation of trade secrets); (d) an
allegation that the Device comprising part of the Initial Product infringes the patents of a Third
Party (except to the extent such infringement arises from the use or combination of such Device
with goods, materials, or services not supplied by Alexza, or any modification or alteration of
such Device by anyone other than Alexza, where such infringement would not have arisen except for
such use, combination, modification or alteration) and/or (e) any Alexza Design Defect. “Alexza
Design Defect” shall be a defect in the design of the Device included in a Product or the Staccato
Technology used to develop a Product. The foregoing indemnity obligation shall not apply to the
extent such Third Party Claims result from (i) Endo’s breach of this Agreement; (ii) the negligence
or willful misconduct of, or violation of applicable law by, such Endo Indemnitee; and/or (iii)
Endo’s or such Endo Indemnitee’s breach of a contractual or fiduciary obligation owed by it to a
Third Party (including without limitation misappropriation of trade secrets).

     13.3 Indemnification Procedures. A Party seeking indemnification under Sections 13.1 or 13.2
hereof (the “Indemnitee”) shall promptly notify the other Party (the “Indemnitor”) in writing of
any claim, lawsuit or other action in respect of which the Indemnitee, its Affiliates, or any of
their respective directors, officers, employees and agents intend to claim such indemnification.
The Indemnitee shall permit, and shall cause its Affiliates and their respective directors,
officers, employees and agents to permit, (i) the Indemnitor to have complete control of such
defense (except as set forth below) so long as it promptly assumes the defense and prosecutes the
defense with appropriate diligence and care and (ii) the Indemnitor, at its discretion, to settle
any such claim, lawsuit or other action with the prior written consent of the Indemnitee, provided,
however, that such consent shall not be unreasonably withheld or delayed so long as such settlement
does not adversely affect the Indemnitee’s rights hereunder or impose any obligations on the
Indemnitee in addition to those set forth herein. No such claim, lawsuit or other action shall be
settled by the Indemnitee without the prior written consent of the Indemnitor and the Indemnitor
shall not be responsible for any legal fees or other costs incurred other than as provided herein.
The Indemnitee, its Affiliates and their respective directors, officers, employees and agents shall
cooperate fully with the Indemnitor and its legal representatives in the investigation and defense
of any claim, lawsuit or other action covered by this indemnification. The Indemnitor, if it is
directing the defense as set forth above, shall keep

been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

the Indemnitee reasonably informed of the progress of the action and shall consider the
comments and observations of the Indemnitee timely given in the course of the proceedings. The
Indemnitee shall have the right, but not the obligation, to be represented by counsel of its own
selection and expense. Notwithstanding the foregoing, the Indemnitee may be represented by separate
counsel at the expense of the Indemnitor if a conflict of interest exists between the interests of
the Indemnitor and Indemnitee so that a single counsel representing Indemnitor cannot adequately
defend the rights of the Indemnitee

     13.4 Survival of Indemnification Obligations. The provisions of this Article 13 shall survive
the termination or expiration of this Agreement.

     13.5 Insurance. The Parties shall maintain insurance or self-insurance against such risks and
in such amounts as are usually maintained or insured against by other companies of established
repute engaged in the same or a similar business. Each Party shall submit to the other Party
evidence of the insurance or self-insurance that is carried by such Party upon written request of
the other Party.

expiration or termination of this Agreement in its entirety, unless otherwise directed by Alexza,
Endo shall promptly return all Alexza Confidential Information to Alexza, except for a single copy
and/or sample to be retained for documentation purposes only and except that Endo, its Affiliates
and any Third Party manufacturer shall be entitled to retain such Confidential Information relating

agreed, and Alexza shall have the right to use any such information in developing and
commercializing Products, and to license any Third Parties to do so.

          (f) Payment of Certain Costs. Upon the termination of this Agreement by Endo pursuant to
Section 14.2(a) or by Alexza under Section 14.2(c), Endo shall reimburse Alexza for [ * ] of (i)
any non-cancellable capital expenses incurred by Alexza as of the date of termination in order to
increase Alexza’s capacity for Manufacturing Product (whether at its Plant or in connection with

validating a Third Party manufacturer as an alternative source of supply of the Product, in
each case to the extent such activities were consistent with a mutually agreed written plan and
budget for expanding Manufacturing capacity or such activities were, at the time such activities
were initiated, reasonably determined by Endo to be an appropriate course of action in accordance
with Section 5.1(d) to ensure that Alexza would be able to fulfill Endo’s requirements of Product
in excess of the Volume Commitment within the [ * ] based on Endo’s most recent forecast. Such
payment shall be due no later than (60) days following receipt of a written invoice from Alexza.

          (g) Accrued Obligations. Except as set forth herein, any termination or expiration of this

          (h) Cumulative Remedies. Except as expressly stated otherwise in this Agreement, remedies
under this Agreement are cumulative, and termination of this Agreement in accordance with and
fulfillment of all obligations set forth in this Article 14 shall not affect any other rights or
remedies that may be available to a Party in law or equity. In addition, nothing in this Agreement
shall prevent either Party, in the case of a breach, from not terminating this Agreement and
seeking to enforce its rights hereunder.

          (i) Survival. The terms of Sections 3.4, 4.1(e), 4.2(c), 4.3, 4.4, 4.5, 5.1(e), 7.9, 9.2,

     15.2 Entire Agreement. This Agreement (including any Exhibits or other attachments hereto)
constitutes the entire agreement between the Parties with respect to the subject matter hereof, and
no oral or written statement may be used to interpret or vary the meaning of the terms and
conditions hereof. This Agreement supersedes any prior or contemporaneous agreements and
understandings, whether written or oral, between the Parties with respect to the subject matter
hereof, including the Confidentiality Agreement between Alexza and Endo dated February 9, 2007 (the

Alexza Confidential Information for the purposes of this Agreement.

     15.3 Assignment. Neither Party may assign or otherwise transfer this Agreement without the
prior written consent of the other Party; provided, however, that either Party may assign this

under this Agreement to the extent that such performance is prevented by force majeure and the
nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse
shall be continued so long as the condition constituting force majeure continues and the
nonperforming Party takes reasonable efforts to minimize the effect of and overcome or remove the
cause or condition causing such force majeure. For purposes of this Agreement, force majeure shall
include conditions beyond the control of the Parties, including, without limitation, an act of God,
war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of
public utilities or common carriers, destruction of production facilities or materials by fire,
earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such

type of undertaking under the same or similar

circumstances). Notwithstanding the foregoing, a Party shall not be excused from making
payments owed hereunder because of a force majeure affecting such Party. In the event that either
Party is prevented or delayed in performing any of its obligations under this Agreement due to
force majeure for an aggregate period in excess of ninety (90) days in any twelve month period, the
Parties shall meet as soon as practicable to discuss in good faith how best to alleviate the
circumstances in question.

     15.5 Headings. The descriptive headings contained in this Agreement are for convenience of
reference only and shall not affect in any way the meaning or interpretation of the Agreement.

     15.6 Independent Contractor. Each Party shall be acting as an independent contractor in
performing under this Agreement and shall not be considered or deemed to be an agent, employee,
joint venturer or partner of the other Party.

     15.7 Severability. If any term or other provision of this Agreement is invalid, illegal or
incapable of being enforced by any law or public policy, all other terms and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner materially adverse
to any Party.

     15.8 No Third-Party Beneficiaries. Nothing in this Agreement, either express or implied, is
intended to or shall confer upon any third party any legal or equitable right, benefit or remedy of
any nature whatsoever under or by reason of this Agreement.

     15.9 Amendment. This Agreement may not be amended or modified except by an instrument in
writing signed by authorized representatives of Endo and Alexza.

     15.10 Governing Law. This Agreement shall be governed by, and construed in accordance with,
the laws of the State of New York without reference to choice of law rules.

     15.11 Dispute Resolution. In the event of any dispute under this Agreement (other than
disputes excluded in subsection (a) below), the Parties shall refer such dispute to the CEOs for
attempted resolution by good faith negotiations within thirty (30) days after such referral is
made. If the CEOs are unable to resolve the dispute within the time allotted, either Party may
proceed as set forth below.

          (a) Alternative Dispute Resolution. Any dispute, controversy or claim arising out of or
relating to the validity, construction, enforceability or performance of this Agreement, including
disputes relating to an alleged breach or to termination of this Agreement and including any claim
of inducement by fraud or otherwise, but excluding any dispute, controversy or claim arising out of
or relating to the validity, enforceability, or infringement of any Alexza Patent or any suit for
injunctive relief under Section 15.12 (which shall be submitted to a court of competent
jurisdiction), shall be settled by mediation and arbitration in the manner described below:

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has
been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

          (b) Mediation. The CEOs shall select a mediator with appropriate expertise in the subject
matter to which the dispute relates, who will be engaged to resolve the dispute. If the CEOs
cannot agree on a mediator within fifteen (15) days, each Party may seek appropriate resolution
through arbitration as described below. If the Parties are unable to resolve their dispute through
mediation within ninety (90) days after selection of the mediator(s), either Party may seek
appropriate resolution through arbitration as described below.

          (c) Arbitration. Any dispute, controversy or claim arising out of or relating to the
validity, construction, enforceability or performance of this Agreement which is not resolved by
mediation, including disputes relating to alleged breach or to termination of this Agreement (other
than disputes referred to in Section 15.11(a) that are to be submitted to a court of competent
jurisdiction), shall be settled by binding arbitration (“Arbitration”) in the manner described
below:

               (i) If a Party intends to begin an Arbitration to resolve a dispute, such Party shall
provide
written notice (the “Arbitration Request”) to the other Party informing such other Party of such
intention and the issues to be resolved. From the date of the Arbitration Request and until such
time as any matter has been finally settled by Arbitration, the running of the time periods
contained in Article 14 as to which Party must cure a breach of this Agreement shall be suspended
as to the subject matter of the dispute. Within ten (10) Business Days after the receipt of the
Arbitration Request, the other Party may, by written notice to the Party initiating Arbitration,
add additional issues to be resolved.

          (d) Procedure. The Arbitration shall be conducted pursuant to the then-current JAMS/ENDISPUTE
Rules (streamlined for disputes involving [ * ] or less and comprehensive for disputes involving
more than [ * ] or involving a right to terminate this Agreement under Section 14.2(c) or (d)).
Notwithstanding those rules, the following provisions shall apply to the ADR hereunder:

               (i) Arbitrator. In the event that the dispute at issue involves an amount less than
[ * ],
the Arbitration shall be conducted by one (1) arbitrator (the “Threshold 1 Arbitrator”). In the
event, however, that the dispute at issue involves an amount greater than
[ * ] or the termination of this Agreement under Section 14(c) or (d), the Arbitration shall
be conducted by a panel of three (3) arbitrators (collectively, with the Threshold 1 Arbitrator,
the “Arbitrators”). The Arbitrators shall be selected from a pool of retired independent federal
judges to be presented to the Parties by JAMS/ENDISPUTE. Neither Party shall engage in ex parte
contact with the arbitrators.

               (ii) Proceedings. The Arbitrators shall render a written opinion setting forth findings
of
fact and conclusions of law with the reason therefor stated. A transcript of the evidence adduced
at the hearing shall be made and, upon request, shall be made available to each Party. The
Arbitrators shall, in rendering their decision, apply the substantive law set forth in Section
15.10, except that the interpretation of and enforcement of this Section 15.11 shall be governed by
the Federal Arbitration Act. The Arbitrator shall apply the Federal Rules of Evidence to the
hearing. The proceeding shall take place in Chicago, Illinois and shall be conducted in such a
manner so that the written opinion of the Arbitrators is given with 180 days

 

			
	[ * ] = 	 	 Certain confidential information contained in this document, marked by brackets, has

24b-2 of the Securities Exchange Act of 1934, as amended.

 

 

after the Arbitrators are selected. The fees of the Arbitrators and JAMS/ENDISPUTE shall be
paid by the losing Party, which shall be designated by the Arbitrator(s). If the Arbitrator(s) is
unable to designate a losing Party, it shall so state and the fees shall be split equally between
the Parties.

               (iii) Award. Subject to Section 15.12, the Arbitrator(s) is empowered to award any
remedy
allowed by law, including money damages, prejudgment interest and attorneys’ fees, and to grant
final, complete, interim, or interlocutory relief, including injunctive relief.

               (iv) Costs. Except as set forth in Sections 15.11(d)(ii) and (iii) above, each
Party shall
bear its own legal fees and costs.

               (v) Confidentiality. The ADR proceeding shall be confidential and the Arbitrators shall
issue
appropriate protective orders to safeguard each Party’s Confidential Information. Except as
required by law, no Party shall make (or instruct the Arbitrators to make) any public announcement
with respect to the proceedings or decision of the Arbitrators without prior written consent of
each other Party. The existence of any dispute submitted to ADR, and the award, shall be kept in
confidence by the Parties and the Arbitrators, except as required in connection with the
enforcement of such award or as otherwise required by applicable law.

               (vi) Judgment; Provisional Remedies. Any court having jurisdiction of this matter may
enter
judgment upon any award granted under this Section 15.11. Each Party has the right before or
during the arbitration to seek and obtain from the appropriate court provisional remedies such as
attachment, preliminary injunction, replevin, etc. to avoid irreparable harm, maintain the status
quo, or preserve the subject matter of the arbitration.

               (vii) Language. All pleadings, complaints and other documents filed or presented in
connection with, and all proceedings in, any dispute resolution proceeding described in this
Section 15.11 must be in the English language.

     15.12 Injunctive Relief. Each Party shall be entitled to seek injunctive relief to enforce
the respective covenants and agreements of the Parties in this Agreement, including, without
limitation, the respective rights and obligations of the Parties under Articles 5, 8 and 10.

     15.13 Waiver of Jury Trial. EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY.

     15.14 Limitation of Liability. IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR
LOST PROFITS OR FOR ANY SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, HOWEVER
CAUSED, ON ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES, ARISING UNDER ANY CAUSE OF ACTION AND ARISING IN ANY WAY OUT OF THIS
AGREEMENT. THE FOREGOING LIMITATION WILL NOT LIMIT EITHER PARTY’S LIABILITY FOR

BREACH OF ARTICLE 10 OR EITHER PARTY’S INDEMNIFICATION OBLIGATIONS TO THE OTHER PARTY UNDER
ARTICLE 13.

     15.15 No Waiver. The failure of either Party to enforce at any time for any period the
provisions of or any rights deriving from this Agreement shall not be construed to be a waiver of
such provisions or rights or the right of such Party thereafter to enforce such provisions.

     15.16 Counterparts. This Agreement may be executed in one or more counterparts, and by the
respective Parties in separate counterparts, each of which when executed shall be deemed to be an

Exhibit 10.38

January 23, 2008

Michael J. Simms

1879 Los Altos Drive

San Mateo, CA 94402

Dear Mike:

On behalf of Alexza Pharmaceuticals, we are pleased to offer you the position in the
company as Senior Vice President, Operations and Manufacturing, reporting to the
President and CEO, Tom King. This is a Corporate Officer and Executive Team member,
and full-time offer to work at the new Alexza Pharmaceuticals facilities located on
Stierlin Court in Mountain View, California, beginning on or about February 18, 2008
(actual date to be determined). This offer is contingent upon any pre-employment
background check required for DEA and other regulatory agency compliance. To
facilitate these requirements, please complete and sign the enclosed background
check release form.

Your initial monthly base salary will be $26,250.00 payable in accordance with the
Company’s customary payroll practice for salaried exempt positions. This equates to
base compensation of $315,000 on an annualized basis. We are in the process of
finalizing our 2008 Bonus Plan with our Board of Directors and you would be eligible
to participate in that plan at the Senior Vice President level. We anticipate the
plan to be similar to our 2007 plan. That plan was based upon the achievement of a
combination of our corporate goals, as well as your personal and department goals
established and agreed upon by yourself and your manager, with the opportunity to
earn up to 45% of your earned salary for 2008. In the event that we do not put a
bonus plan in place during 2008, we will guarantee a 35% bonus payout of your earned
salary for 2008. We will also provide you a signing bonus of $50,000 (less
applicable payroll taxes) and would be payable in the first pay period after your
start date.

We will also grant you an option to purchase 175,000 shares of common stock. This
option grant will be subject to all the standard terms and conditions of the Alexza
2005 Equity Incentive Plan. The option will vest over a 48-month period, with 1/4 of
the shares vesting after 12 months and the remainder vesting on a monthly basis
thereafter.

You will also be eligible to participate in our Employee Stock Purchase Plan, which
is a payroll deduction plan that offers eligible employees the opportunity to
purchase Alexza common stock at a discount to the market price. Participants may
authorize after-tax deductions of up to 20% of their base compensation for the
purchase of stock under the 2005 Employee Stock Purchase Plan. Detailed provisions
of the Plan are outlined in the Plan Document.

 

 

In addition, as a Senior Vice President at Alexza, you will execute a Severance
Agreement that will entitle you to a severance benefit upon a change of control of
Alexza on the terms and conditions described in our public filings.

Should you decide to accept our offer, you will be an “at-will” employee of Alexza.
This means that either you or Alexza may terminate the employment relationship with
or without cause at any time. Participation in any benefit, compensation or bonus
program does not change the nature of the employment relationship, which remains
“at-will”. The Vice President positions have “change of control” provisions as
outlined in Alexza corporate documents.

To enable Alexza to safeguard its proprietary and confidential information, it is a
condition of your employment that you sign Alexza’s standard Employee Invention
Assignment and Confidentiality Agreement. A copy of this agreement is enclosed for
your review and signature. We understand that you are likely to have signed similar
agreements with prior employers, and wish to impress upon you that Alexza does not
want to receive the confidential or proprietary information of others, and will
support you in respecting your lawful obligations to prior employers.

As an executive with over over 20 years previous work history, you will be eligible
for 20 days of flexible time off (vacation plus sick leave) during your first year
of employment, following your three-month anniversary of full-time employment.

You will also be eligible for medical, dental, vision and life insurance for
yourself and your immediate family. Alexza Pharmaceuticals sponsors a 401(k) plan
to which employees can make contributions. You will be eligible to participate in
this 401(k) plan on the first day of the month coincident with or following your day
of hire. Upon acceptance of this offer of employment, we will provide the materials
to you to apply for coverage under Alexza Pharmaceuticals’ health insurance plan.

This letter contains our complete understanding and agreement regarding the terms of
your employment by Alexza and supersedes in their entirety all other or prior
agreements by you with the Company as to the specific subjects of this letter. This
binding agreement may only be amended in a writing signed by both you and the
Company, although it is understood that Alexza may, from time to time, in its sole
discretion, adjust the salaries, incentive compensation and benefits paid to you and
its other employees, as well as job titles, locations, duties, responsibilities,
assignments and reporting relationships.

If you agree with the terms of this offer letter, please sign below and fax this
page along with the completed Background Check Authorization Form to Alexza
Pharmaceuticals at (650) 687-6698 by January 30, 2008, upon which date this offer
expires. Upon your signature below, this will become our binding agreement with
respect to the subject matter of this letter.

 

 

We look forward to a long and mutually rewarding relationship with you as a member
of the Alexza team. With very best regards.

Sincerely,

/s/ Emily Lee Kelly
