possession. 

 Except as modified herein, Landlord and Tenant hereby ratify and reconfirm each provision of the existing Lease.
The provisions of the Amendment shall supersede any inconsistent or conflicting provisions of the original Lease.

consents to and authorizes the grant to Lupin of, a fully paid up, royalty free, non-exclusive (except as otherwise provided herein) license with respect to the Depomed Patents, with the right to grant sublicenses to Affiliates, (i) to make,
have made, use, promote, offer to sell, sell, import, or otherwise dispose of Licensed Products in or for the Territory, and (ii) to make and have made the Licensed Products outside the Territory only for use, sale and importation in or for the
Territory. Further, in connection with the Depomed Products, Santarus and Depomed agree to waive and hereby waive, for themselves and their Affiliates, any and all regulatory exclusivities (including, without limitation, pediatric exclusivity)
vis-à-vis the Licensed Products only that may prevent the approval of the Licensed Products in the Territory under the Lupin ANDA on or after the License Effective Date, as may be accelerated pursuant to the terms herein. At Lupin’s

Section 3.2.Covenant Not To Sue. With respect to the Licensed Products, and effective on the Effective Date (subject to
Lupin’s compliance with this Agreement, including Section 3.3), Depomed, Santarus and their Affiliates covenant not to sue Lupin and its/or their Affiliates, Related Parties, and their manufacturers, importers, suppliers, distributors,
marketing partners and customers, or support or encourage any Third Party to sue, for infringement of any Depomed Patents, or any United States or foreign patent application or any other issued United States or foreign patent owned, licensed or

Licensed Products. Depomed, Santarus and their Affiliates further covenant that for any patent owned, licensed or controlled by Depomed, Santarus or their Affiliates listed in the future in the
Orange Book for the Depomed Products, the foregoing Covenant Not To Sue shall hereby be treated to also be in the form of a non-exclusive license limited to the Licensed Products, for the sole purpose of permitting Lupin and its Affiliates to file a
“Paragraph IV Certification” against such patents under 21 U.S.C. § 355(j)(2)(A)(vii)(IV) (as amended or replaced). Lupin shall have the right to maintain its existing “Paragraph IV Certification” under 21 U.S.C.
§ 355(j)(2)(A)(vii)(IV) (as amended or replaced) against the Depomed Patents and as to any other patent listed in the FDA’s Orange Book in connection with the Depomed Products. Lupin also shall have the right to file a new Paragraph
IV Certification against any patents listed in the future in the FDA’s Orange Book for the Depomed Products and still be covered by the Covenant Not To Sue provided for in this Section 3.2. 

Section 3.3. Restrictions Prior to License Effective Date. Except as permitted by this Section 3.3, Lupin and their
Affiliates and Related Parties shall not make, have made, import into, distribute, offer to sell, or sell in the Territory any Licensed Products prior to the License Effective Date. Lupin agrees that any breach by either or both of them, or their
Affiliates and/or Related Parties, of this Section 3.3 shall cause irreparable harm to Depomed and Santarus, and Lupin and their Affiliates, and their Related Parties consent irrevocably and unconditionally to specific performance, or immediate
entry of a temporary restraining order, preliminary injunction, and permanent injunction, to enforce this Section 3.3. Notwithstanding anything to the contrary, Lupin, their Affiliates and their Related Parties consent irrevocably and
unconditionally to personal jurisdiction and venue in the United States District Court for the Northern District of California for the purpose of enforcing this provision. Notwithstanding the foregoing, Lupin shall have the right and license under
this Agreement to engage in the following activities: 
 (a) ***; and 

(b) ***. 

Section 3.4. Impact of Granting Certain Licenses To Third Parties. In the event that Depomed or Santarus or any of their
Affiliates enters into an agreement with any Third Party or an Affiliate granting such party a license, sublicense, covenant or other agreement or authorization, as applicable, to Market in the Territory a Generic Equivalent of the Depomed Products
prior to *** after *** then the License Effective Date in this Agreement shall automatically be amended to be the date that is *** prior to the date such Third Party or Affiliate is permitted to Market such Generic Equivalent of the Depomed Products
in the Territory under the license, sublicense, covenant or other agreement or authorization from Depomed, Santarus and/or their Affiliates. For avoidance of doubt, Depomed, Santarus and their Affiliates shall not enter into any agreement with any
Third Party or Affiliate granting such party a license, sublicense, covenant or other agreement or authorization, as applicable, to Market in the Territory a Generic Equivalent of the Depomed Products any earlier than *** after the License Effective
Date (as such License Effective Date may be accelerated pursuant to this Agreement). Depomed and Santarus shall provide Lupin with reasonable advance notice of any Third Party or Affiliate permitted a Marketing date that is earlier than *** after

 Section 3.5. *** 

Section 3.6. *** Notwithstanding the provisions of Sections 3.4 and 3.5, Depomed and Santarus shall have the right to: ***

 Section 3.7. Impact Of Final Court Decision. In the event of a Final Court Decision in a proceeding involving a
Third Party proposing to market a Generic Equivalent prior to the License Effective Date of invalidity and/or unenforceability and/or non-infringement of each of the unexpired claims of the Depomed Patents asserted and adjudicated in such
proceeding, then the License Effective Date shall automatically be accelerated and amended to the date of such Final Court Decision. 
 Section 3.8. No Interference But No Consent for FDA Approval. Depomed and Santarus shall not, and shall not cause any Affiliate or Third Party to: (a) initiate any activity (including but
not limited to the filing of any citizen petitions or litigation against the FDA) to interfere with or obstruct Lupin’s efforts to (i) obtain FDA approval of the Lupin ANDA, or (ii) launch Lupin’s ANDA Products as of the date and
under the terms provided by this Agreement; and/or (b) unless required by law, (i) delist or cancel the Depomed Products or NDA No. 21-748 with the FDA, (ii) delist or remove any Depomed Patents, or the Depomed Products or NDA
21-748, from the FDA’s Orange Book, (iii) seek or otherwise undertake any action with the FDA to withdraw the Depomed Products from the market, or (iv) delete, remove, designate as “obsolete” or cancel any National Drug
Code(s) or any other relevant code(s) for the Depomed Products from the applicable National Drug Data File maintained by First Databank (or any successor or equivalent organization), or from any other pricing database. Neither this Agreement nor
this Section shall be interpreted as Depomed’s or Santarus’ consent to approval from the FDA or any other applicable regulatory authority for Lupin to market a product containing metformin in the Territory. As Lupin may reasonably request,
Depomed and Santarus will submit, or will cause their Affiliates to submit, appropriate and reasonable documentation to the FDA evidencing this Agreement. Notwithstanding the above, this Section does not preclude Depomed, Santarus and/or their
Affiliates from taking any action necessary or commencing a Proceeding to secure or maintain their statutory rights under 21 U.S.C. §355a. 
 Section 3.9. Limited Use of Agreement Outside Territory. Depomed, Santarus and Lupin agree that neither will use this Agreement or the Consent Injunction and Dismissal Order outside of the
Territory for any purpose except to enforce the Agreement. 
 Section 3.10. Effect of Third Party Launch After Trial
Court Decision. If, prior to the License Effective Date, any Third Party launches any Generic Equivalent after a trial court enters a final judgment holding that each of the unexpired asserted and adjudicated claims of the Depomed Patents is
invalid or unenforceable or not infringed (a “Third Party At-Risk Launch”), Lupin has the option of launching Lupin’s ANDA Products at that time (“Lupin At-Risk Launch”) only under the following conditions:

 (a)Lupin agrees that during such Lupin At-Risk Launch, if Depomed and/or Santarus obtains a court order from any court
requiring, or if Depomed and/or Santarus and any Third Party enter into an agreement that requires, the cessation of sales of the Generic Equivalent that is the subject of the Third Party At-Risk Launch, Lupin will cease further shipping and At-

Risk sales of Lupin’s ANDA Products and any other infringing activities until the occurrence of the License Effective Date (including any acceleration of the License Effective Date under the
terms of this Agreement) or until the occurrence of another Third-Party At-Risk Launch. 
 (b) Notwithstanding Section 2.1
above, in the event of a Final Court Decision as to the foregoing Third Party launching the Generic Equivalent that any claims of the Depomed Patents asserted in the Third Party proceeding are not invalid and not unenforceable and that such claims
are infringed, ***, and Lupin reserves all rights to contest and defend against, and to assert any and all defenses to, such a claim except that Lupin may not contest and may not raise as a defense the invalidity or unenforceability of any asserted
Depomed Patent claim that such Final Court Decision affirms as valid and/or enforceable. 
 Section 3.11. Effect of
Third Party Launch Before Trial Court Decision. If, prior to the License Effective Date, any Third Party launches any Generic Equivalent prior to a trial court entering a final judgment holding that each of the unexpired asserted and adjudicated
claims of the Depomed Patents is invalid or unenforceable or not infringed (a “Third Party True At-Risk Launch”), Lupin has the option of launching Lupin’s ANDA Products (“Lupin True At-Risk Launch”) only under
the following conditions: 
 (a) Lupin may commence Lupin True At-Risk Launch no earlier than *** after the Third Party True
At-Risk Launch, and only after providing Depomed and Santarus written notice *** before any intended True At-Risk Launch. 
 (b)
Lupin agrees that during any such Lupin True At-Risk Launch, if (i) Depomed obtains a court order from any court requiring, or Depomed and/or Santarus and any Third Party enter into an agreement that requires, the cessation of sales of the
Generic Equivalent that is the subject of the Third Party True At-Risk Launch or (ii) the Third Party ceases sales of the Generic Equivalent that is the subject of the Third Party True At-Risk Launch, by agreement or otherwise, before the
expiration of the *** period in Section 3.11(a), Lupin will cease any shipping and True At-Risk sales of Lupin’s ANDA Products and any other infringing activity until the occurrence of the License Effective Date (including any acceleration
of the License Effective Date under the terms of this Agreement), or until the occurrence of another Third-Party True At-Risk Launch. For the avoidance of doubt, this paragraph does not terminate Lupin’s right to invoke the provisions of
Sections 3.7 and/or 3.10 if they become applicable before the License Effective Date. 
 (c) Notwithstanding Section 2.1
above, in the event there is a Final Court Decision with the Third Party launching the Generic Equivalent under this Section 3.11 that any claims of the Depomed Patents asserted in the Third Party proceeding are not invalid and not
unenforceable and that such claims are infringed, *** and before any reliance by Lupin on the provisions of Sections 3.7 and/or 3.10, and Lupin reserves all rights to contest and defend against, and to assert any and all defenses to, such a claim
except that Lupin may not contest and may not raise as a defense the invalidity or unenforceability of any asserted Depomed Patent claim that such Final Court Decision affirms as valid and/or enforceable. 

Section 3.12. Reservation of Rights. All rights not expressly granted to Lupin hereunder are expressly reserved to Depomed
and Santarus, and neither Depomed nor Santarus has any

obligation to make available any intellectual property rights or to take any other actions other than as expressly set forth herein. Except as expressly provided herein, nothing in this Agreement
shall be construed as granting Lupin or their Affiliates, subsidiaries or Related Parties any rights: (a) with respect to any Licensed Products outside the Territory; (b) with respect to any product other than Licensed Products; or
(c) to make, have made, use, offer to sell, sell, import, or otherwise dispose of any generic version of any Depomed Products covered by Depomed Patents at any time prior to the License Effective Date. 

Section 3.13. *** 
 (a) *** During each calendar quarter, commencing on the Effective Date and terminating on the date that is three (3) months prior to the License Effective Date, *** 

(b) *** During each calendar year (and prorated for any partial calendar years), commencing on the Effective Date and terminating on the
date that is three (3) months prior to the License Effective Date, *** 
 (c) Reporting. Commencing on the Effective
Date and terminating on the date that is three (3) months prior to the License Effective Date (the “Reporting Period”), Santarus or Depomed shall provide Lupin with the following periodic reports: (i) within *** following
the end of each calendar quarter during the Reporting Period, a report of the ***; and (ii) within *** following the end of each calendar year during the Reporting Period, a report of the ***. 

(d) *** In the event that Santarus and/or Depomed: (i) fail to perform the aggregate *** obligations set forth in
Section 3.13(a) during any calendar quarter during the Reporting Period; or (ii) fail to perform the aggregate *** obligations set forth in Section 3.13(b) during any calendar year period during the Reporting Period (each, a
“Failure Event”), then Lupin shall provide each of Depomed and Santarus with written notice specifying the alleged Failure Event (the “Lupin Notice”). Santarus and/or Depomed shall have an opportunity to dispute the
facts underlying the alleged Failure Event (or provide evidence of a cure, as described below) by providing written notice to Lupin within *** following the date of the Lupin Notice (the “Response Notice”). In the event that

Event has occurred pursuant to Section 3.13(d) shall be resolved by arbitration before a single arbitrator in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) then pertaining
(available at http://www.adr.org), except where those rules conflict with this provision, in which case this provision controls. Any court with jurisdiction shall enforce this clause and enter judgment on any final determination. The AAA shall
select the arbitrator within *** from commencement of the arbitration from the AAA’s National Roster of Arbitrators pursuant to agreement or through selection procedures administered. Within *** of initiation of arbitration, the Parties shall
reach agreement upon and thereafter follow procedures, including without limitation limits on discovery, assuring that the arbitration will be concluded and the final determination rendered within no more than *** from selection of the arbitrator
or, failing agreement, procedures meeting such time limits will be designed by the AAA and adhered to by the Parties. The arbitration shall be held in San Francisco, California and the arbitrator shall apply the substantive law of California, except
that the Federal Arbitration Act shall govern the interpretation and enforcement of this arbitration provision. Prior to appointment of the arbitrator or thereafter if he is unavailable, emergency relief is available from any court to avoid
irreparable harm.

           Defendants.	 	

 CONSENT INJUNCTION AND DISMISSAL ORDER 

This action for alleged patent infringement (the “Litigation”) has been brought by Plaintiff Depomed, Inc.
(“Depomed”) against Defendants Lupin Pharmaceuticals, Inc. and Lupin Limited (collectively, “Lupin”) for alleged infringement of United States Patent Nos. 6,635,280, 6,340,475, and 6,488,962 (collectively the “Depomed
Patents”). Depomed’s commencement of the Litigation was based on its receipt of notice from Lupin Limited that Lupin Limited had filed Abbreviated New Drug Application (“ANDA”) No. 91-664 with the United States Food and Drug
Administration containing a certification pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(IV) directed to the Depomed Patents and seeking approval to market 500 mg and 1000 mg metformin tablets as a generic version of Glumetza®. 
 Depomed and Lupin have agreed to enter into a good faith final settlement agreement (the “Settlement and License Agreement”) regarding this Litigation on the expectation and belief that this
would eliminate the substantial litigation costs that would otherwise be incurred by both Depomed and Lupin during the Litigation, while also serving the public interest by saving 

  
 - 1 -

 
judicial resources and avoiding the risks to each of the parties associated with infringement. The Settlement and License Agreement will afford Depomed and Lupin the procompetitive opportunity to
more productively use money and other resources that would have been spent in the continued prosecution and defense of this Litigation, to the benefit of the parties and consumers alike, such as by investing more money in pharmaceutical research and
development. 
 Each of Depomed and Lupin acknowledge there is significant risk to each of them associated with the continued
prosecution of this Litigation and have consented to entry of this order through a final settlement as reflected herein. The Court, upon the consent and request of Depomed and Lupin, hereby issues the following Order. 

Depomed and Lupin now consent to this Consent Injunction and Dismissal Order and 

IT IS HEREBY ORDERED that: 
 1. Subject matter jurisdiction, personal jurisdiction, and venue are all proper in this Court. 
 2. In this Litigation, Depomed has charged Lupin with infringement of the Depomed Patents in connection with Lupin Limited’s submission of ANDA No. 91-664 directed to generic tablets containing
500 mg or 1000 mg of metformin per tablet to the U.S. Food and Drug Administration (“FDA”). 
 3. In response to
Depomed’s charges of patent infringement, Lupin has alleged certain defenses and counterclaims, including that the Depomed Patents are invalid or not infringed. The Court has not adjudicated Depomed’s charges of patent infringement or
Lupin’s defenses and counterclaims. 
 4. Lupin has agreed that each of the defenses and counterclaims set forth in its
Answer, Affirmative Defenses and Counterclaims, including the allegations and averments contained therein, should be dismissed, without prejudice. 

  
 - 2 -

 5. Lupin, their officers, agents, servants, employees and attorneys, and those persons in
active concert or participation with them who receive actual notice of this Order by personal service or otherwise, are hereby enjoined from manufacturing, using, offering to sell or selling within the United States and its territories and
possessions, including the Commonwealth of Puerto Rico (the “Territory”), or importing into the Territory, any generic tablet product containing 500 mg or 1000 mg of metformin per tablet that is the subject of ANDA No. 91-664 until:

 (a) February 1, 2016; or 
 (b) at such earlier date as may be permitted by the Settlement and License Agreement that the Parties have entered into. 
 6. Depomed and Lupin each expressly waives any right to appeal or otherwise move for relief from this Consent Injunction and Dismissal Order. 

7. All claims and defenses as between Depomed and Lupin are hereby dismissed without prejudice. 

8. This Court retains jurisdiction over Depomed and Lupin for purposes of enforcing this Consent Injunction and Dismissal Order.

 9. The Clerk of the Court is directed to enter this Consent Injunction and Dismissal Order forthwith. 

IT IS SO STIPULATED:
