(vi)          Reports.  Beginning with the first accrual of royalties or other payments due hereunder, Purchaser shall provide to Aradigm a quarterly royalty report as follows: Within 60 days after the end of each quarterly period, Purchaser shall deliver to Aradigm a true and accurate report, giving such particulars of the business conducted by Purchaser, its Affiliates and Licensees, during such quarterly period as are pertinent to account for payments due under this Section 2.06(a).  Such report shall include, as applicable, at least (A) the total of Net Sales during such quarterly period; (B) the calculation of royalties; (C) the calculation of Royalty Revenue for each applicable Non-Sumatriptan Product and (D) the total royalties and other payments due Aradigm.  Simultaneously with the delivery of each such report, Purchaser shall pay to Aradigm the total amount, if any, due to Aradigm for the period of such report.  If no payment is due, Purchaser shall so report.  Aradigm shall not provide to Third Parties any information contained

Section 3.05           Transferred Contracts.  The Transferred Contracts listed on Exhibit C are all of the contracts between Aradigm and any Third Party currently necessary for or primarily related to, the operation of the Business, and true and complete copies of all such Transferred Contracts have been delivered or made available to Purchaser or its representatives.  Each Transferred Contract is in full force and effect and, to Aradigm’s knowledge, Aradigm is not subject to any default thereunder, nor, to Aradigm’s knowledge, is any party obligated to Aradigm pursuant to any such Transferred Contract subject to any default thereunder.  Aradigm has neither breached, violated or defaulted under, nor received notice that Aradigm has breached, violated or defaulted under, any of the terms or conditions of any Transferred Contract.  Aradigm has obtained, or will obtain prior to the Closing, all necessary consents, waivers and approvals of parties to any Transferred Contract as are required thereunder in connection with the Closing, or for any such Transferred Contract to be transferred to Purchaser, and to remain in full force and effect without limitation, modification or alteration after the Closing.  Following the Closing, Purchaser will be permitted to exercise all of the rights Aradigm had under the Transferred

12

Contracts without the payment of any additional amounts or consideration other than ongoing fees, royalties or payments which Aradigm would otherwise be required to pay pursuant to the terms of such Transferred Contracts had the transactions contemplated by this Agreement not occurred.

Section 3.06           Transferred Intellectual Property.

(a)           The Exhibits listing the Transferred Patents and the Transferred Trademarks are, to Aradigm’s knowledge, complete and accurate.  With respect to Transferred Patents, those Transferred Patents that are Registered Patents are currently in compliance with formal legal requirements (including payment of filing, examination and maintenance fees and proofs of use),  and are not subject to any unpaid maintenance fees or taxes falling due within 90 days after the Closing Date.  There are no proceedings or actions known to Aradigm before any court, tribunal (including the United States Patent and Trademark Office (the “PTO”) or equivalent authority anywhere in the world) related to any such Registered Patent.

(b)           To Aradigm’s knowledge, each Registered Patent that is a Transferred Patent is properly filed and is currently pending or issued, and all necessary registration, maintenance and renewal fees in connection with such Registered Patent that is a Transferred Patent have been paid and all necessary documents and certificates in connection with such Registered Patent have been filed with the relevant patent authorities in the United States or foreign jurisdictions in which Aradigm has elected to pursue such Registered Patent, as the case may be, for the purposes of maintaining such Registered Patent.  There are, to Aradigm’s knowledge, no actions that must be taken by Aradigm within 90 days after the Closing Date, including the payment of any registration, maintenance or renewal fees or the filing of any responses to PTO office actions, documents, applications or certificates for the purposes of obtaining, maintaining, perfecting or preserving or renewing any such Registered Patent.  To the extent Aradigm has acquired from any Person any Technology or Intellectual Property Right, in each case that are included in the Assigned Assets, Aradigm has obtained a valid and enforceable assignment sufficient to irrevocably transfer all rights in such Technology and Intellectual Property Rights (including the right to seek past and future damages with respect thereto) to Aradigm.  To the maximum extent provided for by, and in accordance with, applicable laws and regulations, Aradigm has recorded each such assignment of a Registered Intellectual Property Right assigned to Aradigm with the relevant Governmental Body, including the PTO, the U.S. Copyright Office, or their respective equivalents in any relevant foreign jurisdiction, as the case may be.  Aradigm has not claimed a particular status, including “Small Entity Status,” in the application for any Registered Patent that is a Transferred Patent, which claim of status was not at the time made, or which has since become, inaccurate or false or that will no longer be true and accurate as of the Closing Date.

(c)           Aradigm has no knowledge of any misrepresentation regarding, or failure to disclose, any fact or circumstances in any application for any Registered Patent that is a Transferred Patent that would materially and adversely affect the validity or enforceability of such Registered Patent that is a Transferred Patent.

13

(d)           All Registered Intellectual Property Rights included in the Assigned Assets are free and clear of any Liens.  Immediately prior to the Closing, Aradigm is the exclusive owner or exclusive licensee of all Business Intellectual Property.

(e)           Schedule 3.06(e) sets forth a list of all Regulatory Documents.

(f)            All Assigned Assets will be fully transferable, alienable or licensable by Purchaser without restriction and without payment of any kind to any Third Party, including royalty obligations, other than those restrictions and payments Aradigm would be subject to as of the Closing Date with respect to such Assigned Assets had the transactions contemplated by this Agreement not occurred.

(g)           Each material item of Technology used in the conduct of the Business by Aradigm was (i) written and created by then-current employees of Aradigm acting within the scope of their employment or (ii) acquired or licensed by Aradigm from Third Parties who have validly and irrevocably assigned such item to Aradigm, or granted Aradigm a license to use such item of a sufficient scope to cover Aradigm’s use or prior use of thereof in the Business.

(h)           To Aradigm’s knowledge, the conduct of the Business by Aradigm as it was previously conducted does not, infringe or misappropriate any Intellectual Property Right of any person, or constitute unfair competition or trade practices under the laws of any jurisdiction, and Aradigm has not received notice from any person claiming that such conduct by Aradigm infringes or misappropriates any Intellectual Property Right of any person or constitutes unfair competition or trade practices under the laws of any jurisdiction.

(i)            Each employee and consultant of Aradigm that provides services to Aradigm in connection with the Business has entered into a valid and binding written agreement with Aradigm sufficient to vest title in Aradigm of all Technology and Intellectual Property Rights included in the Assigned Assets and created by such employee or consultant in the scope of his or her services or employment for Aradigm.

(j)            Aradigm has not transferred ownership of, nor granted any exclusive license of or exclusive right to use, or authorized the retention of any exclusive rights to use or joint ownership of, any Technology or Intellectual Property Right that is or was used in connection with the Business, to any other person.

(k)           To Aradigm’s knowledge, no person is infringing or misappropriating any Intellectual Property Right included in the Assigned Assets.

(l)            No Business Intellectual Property is subject to any proceeding or outstanding decree, order, judgment or settlement agreement or stipulation against Aradigm or, to Aradigm’s knowledge, against any Third Parties from whom Aradigm acquired or licensed Business Intellectual Property that restricts in any material way the use, transfer or licensing of such Business Intellectual Property by Aradigm or is reasonably likely to affect the validity, use or enforceability of such Business Intellectual Property.

ARTICLE V
OTHER AGREEMENTS AND COVENANTS

Section 5.01           Additional Documents and Further Assurances.  Each Party hereto, at the request of another Party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably requested for effecting completely the consummation of the transactions contemplated hereby.

Section 5.02           Reasonable Cooperation of Purchaser.  Purchaser shall cooperate, to the extent reasonable, with Aradigm’s efforts to obtain any Third Party consents; provided, however, that this Section 6.02 shall not obligate Purchaser to incur any additional expense or liability.

Section 5.03           Reasonable Efforts.  Each of the Parties will use their reasonable efforts to take all action and to do all things necessary, proper, or advisable in order to consummate and make effective the transactions contemplated by this Agreement.

Section 5.04           Indemnification.

(a)           Indemnification of Purchaser.

(i)             Aradigm shall indemnify and hold harmless each of Purchaser and its Affiliates, and the directors, officers, and employees of Purchaser and of such Affiliates, and the successors and assigns of any of the foregoing (collectively, the “Purchaser Indemnitees”), from and against any and all liabilities, damages, settlements, claims, actions, suits, penalties, fines, costs and expenses (including, without limitation, reasonable attorneys’ fees and other expenses of settlement) (any of the foregoing, a “Claim”) incurred by any Purchaser Indemnitee, based upon a Claim of a Third Party, to the extent resulting from the breach of any of Aradigm’s

15

express representations and warranties set forth in Article III of this Agreement.  Aradigm’s obligations to the Purchaser Indemnitees pursuant to this Section 5.04(a)(i) shall be limited, in the aggregate, to amounts actually received by Aradigm by operation of Section 2.06(a)(i).  Notwithstanding the foregoing, Aradigm shall not have any obligation to the Purchaser Indemnitees in respect of any breach of representations and warranties as to which Purchaser has actual knowledge (including for this purpose the actual knowledge of Steve Farr, John Turanin or Jonathan Rigby) prior to the Closing.

(b)           Aradigm shall indemnify and hold harmless the Purchaser Indemnitees from and against all Claims arising from the Excluded Liabilities.

(c)           Indemnification of Aradigm.  Purchaser shall indemnify and hold harmless each of Aradigm and its Affiliates, and the directors, officers, and employees of Aradigm and of such Affiliates, and the successors and assigns of any of the foregoing (collectively, the “Aradigm Indemnitees”), from and against any and all liabilities, damages, settlements, claims, actions, suits, penalties, fines, costs and expenses (including, without limitation, reasonable attorneys’ fees and other expenses of settlement) incurred by any Aradigm Indemnitee, based upon (i) a Claim of a Third Party, to the extent resulting from the breach of any of Purchaser’s express representations and warranties set forth in Article IV of this Agreement, (ii) a Claim relating to product liability concerning any of the Assigned Assets or (iii) a Claim relating to the Assumed Liabilities.

(d)           Procedure.  A Party that intends to claim indemnification under this Section 5.04 (the “Indemnitee”) shall promptly notify the other Party (the “Indemnitor”) in writing of any Claim in respect of which the Indemnitee intends to require such indemnification, and the Indemnitor shall have sole control of the defense and/or settlement thereof; provided that the Indemnitee shall have the right to participate, at its own expense, with counsel of its own choosing in the defense and/or settlement of such Claim.  The indemnification obligations of the Parties in this Section 5.04 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed.  The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such Claim, if prejudicial to Indemnitor’s ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section 5.04, but the omission to so deliver written notice to the Indemnitor shall not relieve the Indemnitor of any liability to any Indemnitee otherwise than under this Section 5.04.  The Indemnitee under this Section 5.04 and its directors, officers and employees shall cooperate fully with the Indemnitor and its legal representatives and provide full information in the investigation of any Claim covered by this indemnification.

(e)           Sole Remedy.  The indemnification rights provided for in this Article V shall constitute the sole and exclusive remedy and the sole basis and means of recourse among the Aradigm Indemnities and the Purchaser Indemnities with respect to Claims arising out of or in connection with any breach of or inaccuracy in any representation, warranty, covenant or agreement contained in this Agreement.

Section 5.05           Covenant Not to Compete.  Aradigm and its Affiliates agree for a period of four (4) years after the Closing Date (the “Initial Period”) not to (i) conduct, participate in or

16

sponsor, directly or indirectly, any activities directed toward the research, development of technologies or products for the delivery of one or more active pharmaceutical ingredients via needle free injection or the manufacture, marketing or distribution of such products (each, a “Competing Activity”) or (ii) appoint, license or otherwise authorize any Third Party, whether pursuant to such license, appointment, or authorization or otherwise to perform any Competing Activities; provided that during the Initial Period, Purchaser (itself or through one or more Third Parties) is diligently pursuing the development (including preclinical development) or commercialization of one or more Products.  Thereafter during the Royalty Term, Aradigm and its Affiliates agree not to develop or commercialize any product for needle free injection of any active pharmaceutical ingredient for which Purchaser (itself or through one or more Third Parties) is then actively developing or commercializing a Product incorporating such active pharmaceutical ingredient (or any prodrug, metabolite, degradant, intermediate, salt form, hydrate, ester, isomer thereof).

ARTICLE VI
MISCELLANEOUS

Section 6.01           Press Releases and Public Announcements.  No Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement prior to the Closing without the prior written approval of the other Party; provided, however, that (a) either Party may make any public disclosure it believes in good faith is required by applicable law and (b) Aradigm may correspond with Third Parties in writings in form and substance reasonably satisfactory to Purchaser with respect to obtaining consents from such Third Parties.  In furtherance of the foregoing sentence, the Parties agree and acknowledge that either party may issue a press release regarding this Agreement and the transactions contemplated herein at a time to be mutually agreed after the Closing Date, which press release shall not provide the financial terms of the Agreement.  The Parties will provide to each other a copy of such press release at least five business days prior to its release and such press release shall be subject to written approval of the receiving Party, which approval shall not be unreasonably withheld or delayed.

Section 6.03           Force Majeure.  Except with respect to the payment of money, in the event either Party hereto is prevented from or delayed in the performance of any of its obligations hereunder by reason of acts of God, terrorism, war, invasion, strikes, riots, earthquakes, storms, fires, energy shortage, acts of government or governmental agencies, or any other cause whatsoever beyond the reasonable control of the Party, the Party so prevented or delayed shall be excused from the performance of any such obligation to the extent and during the period of such prevention or delay.

Section 6.04           Limitation of Liability.  NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY OR ANY THIRD PARTY FOR ANY SPECIAL, CONSEQUENTIAL, EXEMPLARY OR INCIDENTAL DAMAGES (INCLUDING LOST OR ANTICIPATED REVENUES OR PROFITS RELATING TO THE SAME), ARISING FROM ANY CLAIM RELATING TO THIS AGREEMENT, WHETHER SUCH CLAIM IS BASED ON

CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, EVEN IF AN AUTHORIZED REPRESENTATIVE OF SUCH PARTY IS ADVISED OF THE POSSIBILITY OR LIKELIHOOD OF SAME.

Section 6.05           Entire Agreement and Modification.  This Agreement (including the exhibits hereto) constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes any prior understandings, agreements, or representations by or among the Parties, written or oral, to the extent they related in any way to the subject matter hereof.  This Agreement may not be amended except by a written agreement executed by all Parties.

Section 6.08           Successors and Assigns.  This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns.  This Agreement shall not be assigned by either Party without the prior written consent of the other Party, except that either Party may assign this Agreement, in whole or in part, to an Affiliate of such Party or to the successor (including the surviving company in any consolidation, reorganization or merger) or assignee of all or substantially all of its business pertaining hereto.  This Agreement will be binding upon any permitted assignee of either Party.  No assignment shall have the effect of relieving any Party to this Agreement of any of its obligations hereunder.

Transitional Services Agreement

[Attached]

[ARADIGM LETTERHEAD]

August 25,  2006

SJ2 Therapeutics, Inc.

Re:          Transition Services

Ladies and Gentlemen:

SJ2 Therapeutics, Inc. (“SJ2”) and Aradigm Corporation (“Aradigm”) are entering into an Asset Purchase Agreement (the “APA”) dated as of the date of this letter (the “Effective Date”), which, among other things, provides for the sale to SJ2 of certain Aradigm assets related to the development, manufacture, and commercialization of Aradigm’s Intraject Delivery System.

1.             Services.  On the terms and subject to the conditions contained herein, Aradigm shall provide, or shall cause third parties designated or hired by it (such designated third parties, together with Aradigm, the “Service Providers”) to provide to SJ2 the following services (collectively, the “Services”) for the time period through December 31, 2006 (“Expiration Date”):

(a)           General information technology services and support (e.g., e-mail access, computer equipment and software support, network access and support to SJ2’s server only, and other general computer technologies support) within Aradigm’s current systems and procedures until SJ2 vacates Aradigm’s facilities or the Expiration date, which ever is earlier,

(b)           Telephone and fax services and support,

(c)           Aradigm will provide SJ2 with document control support for the activities documented in Aradigm’s current document control processes, using Aradigm’s Document Control System (DCS) database.  Aradigm has assumed that SJ2 will purchase the DCS on or shortly after the Effective Date.  It is Aradigm’s intention to hire a temporary senior level Document Control Specialist, on or shortly after the Effective Date, who will be fully funded by SJ2, to allow Aradigm’s current document control personnel to provide document control support to SJ2 consistent with Aradigm’s current Document Control processes.  If Aradigm is unable to hire a temporary senior level Document Control Specialist, or should the temporary employee hired leave Aradigm for any reason, Aradigm will not be able to provide the services described in this section 1(c).

(d)           Human resources services and support for Aradigm consultants transferring to SJ2,

(e)           Payment for individual Aradigm consultants transferring to SJ2,

1

(f)                                    Technical consulting as available and approved in writing by both parties,

(g)                                 Office facilities, furnishings, and services (e.g., utilities, maintenance, mail, etc.), and

(h)                                 Such other services as Aradigm and SJ2 may agree to as set forth in paragraph 4.
