non-exclusive license (exercisable without payment of royalty or other compensation to any Grantor) to use, license or sublicense any Patent Collateral, Trademark Collateral, Copyright Collateral or Know-How Collateral now owned or licensed or
hereafter acquired or licensed by such Grantor (to the extent and only to the extent any of the foregoing does not constitute Excluded Collateral), wherever the same may be located throughout the world, for such term or terms, on such conditions and
in such manner as the Secured Party shall determine, whether general, special or otherwise, and whether on an exclusive or nonexclusive basis, and including in such license reasonable access to all media in which any of the licensed items may be
recorded or stored and to all computer software and programs used for the compilation or printout thereof. The use of such license or sublicense by the Secured Party shall be exercised, at the option of the Secured Party, and only upon the
occurrence and during the continuation of an Event of Default; provided that any license, sublicense or other transaction entered into by the Secured Party in accordance herewith shall be binding upon each applicable Grantor notwithstanding any
subsequent cure of an Event of Default.” 
 3. MHR’s Forbearance From Exercising Certain License Rights. Prior to a
Foreclosure, with respect to each Novo Nordisk Agreement and on a Novo Nordisk Agreement-by-Novo Nordisk Agreement basis, MHR hereby agrees that upon the occurrence of an Event of Default (as defined in the 2005 Loan Agreement, 2014 Loan Agreement,
Convertible Notes, Bridge Notes or Reimbursement Notes) or other similar event occurring under the Investment Agreements, it will forebear from exercising its license rights under Section 6.5 of the Pledge and Security Agreement or any similar

Nordisk Agreements; provided that: (x) the Novo Nordisk Agreement remains in effect and (y) Novo Nordisk, subject to any applicable cure period, is in material compliance with the Novo Nordisk Agreement and performs all of its
obligations thereunder. For the avoidance of doubt, the immediately foregoing sentence shall not in any manner whatsoever restrict or prevent MHR’s right to effect a Foreclosure with respect to any Licensed IP. Novo Nordisk agrees that any
non-compliance that could reasonably materially adversely affect MHR’s rights and interests in Emisphere under the Investment Agreements or nonpayment of any payment obligations under a Novo Nordisk Agreement or any failure to comply with the
election or other requirements of a licensee under Section 365(n) of the Bankruptcy Code, in each case, shall be deemed a material non-compliance. 

4. MHR License Agreement 

(a) Concurrent with the entry into this Agreement, Institutional Partners IIA and Novo Nordisk shall have executed a license agreement in the
form attached as Exhibit C hereto (the “MHR License Agreement”), provided that the MHR License Agreement shall become effective only with respect to Foreclosed IP, on a Novo Nordisk Agreement-by-Novo Nordisk Agreement basis,
and only immediately upon the satisfaction in full of all of the following conditions precedent (collectively, the “License Conditions”): 

(i) a Foreclosure occurs; 

  
 5 








 (ii) at the time of such Foreclosure, subject to any cure period provided in respect of the
applicable Novo Nordisk Agreement covering such Licensed IP, no material breach by Novo Nordisk in respect of the applicable Novo Nordisk Agreement has occurred and is continuing; and 

(iii) the applicable Novo Nordisk Agreement covering the applicable Foreclosed IP has not been terminated in accordance with its terms (it
being acknowledged and agreed that any Novo Nordisk Agreement that is rejected (whether by a debtor-in-possession, a trustee or otherwise) in a bankruptcy proceeding by Emisphere shall not be deemed to have been terminated in accordance with its
terms for purposes of this Section 4(a)(iii) so long as Novo Nordisk has validly complied with the election requirements of Section 365(n) of the Bankruptcy Code and is in full compliance with the applicable Novo Nordisk Agreement as
required by Section 365(n) of the Bankruptcy Code). 
 (b) The parties hereto hereby agree that so long as and to the extent that Novo
Nordisk has performed and is continuing to perform all of Novo Nordisk’s obligations under the MHR License Agreement, including the obligation to pay the Financial Obligations as and when they become due to Institutional Partners IIA, Novo
Nordisk shall not be obligated to perform any obligations under the applicable Novo Nordisk Agreement to the extent related to the Foreclosed IP, including the obligation to pay to Emisphere any Financial Obligations that would otherwise be owed to
Emisphere in respect of such Foreclosed IP or for any other Licensed IP covered by the same Novo Nordisk Agreement, and any Financial Obligations owing to Emisphere in respect of such Foreclosed IP or any other Licensed IP covered by the same Novo
Nordisk Agreement shall be reduced to zero. Emisphere hereby expressly irrevocably waives any right it has to performance of such obligations, including payment of any such Financial Obligations, and such waiver should not be deemed a setoff of
obligations otherwise owed to Emisphere. 
 (c) Institutional Partners IIA hereby agrees to provide Novo Nordisk with a Foreclosure Notice
promptly following consummation of any Foreclosure. 
 (d) By entry into this Agreement or the execution of the MHR License Agreement, none
of Emisphere, MHR or Novo Nordisk shall be deemed to have waived, limited or extinguished any claims or rights to assert that any of them has breached any agreement or obligation or committed any other act or omission. For the avoidance of doubt,
and without limiting the foregoing, MHR shall not be deemed to have waived, limited or extinguished any claims or rights that it may assert under or with respect to the Novo Nordisk Agreements despite having executed the MHR License Agreement or
such MHR License Agreement having become effective. 
 (e) MHR’s agreement hereunder shall not otherwise affect, modify, change or
amend any of the Investment Agreements, including Section 6.5 of the Pledge and Security Agreement, or MHR’s rights and remedies thereunder, which Investment Agreements shall continue in full force and effect. 

  
 6 








 5. MHR’s Consent to GLP-1 Amendment No. 3 and Expansion License
Agreement. Each of Emisphere and Novo Nordisk hereby acknowledge and agree that Section 4.1 of the Pledge and Security Agreement prohibits each Grantor from entering into any agreement or undertaking restricting the right or ability of
such Grantor or the Secured Party (as defined therein) on its own behalf and on behalf of the Lenders (as defined therein) to sell, assign or transfer any of the Collateral (as defined therein) without the prior written consent of the Secured Party,
except as permitted under the Loan Documents (as defined therein) and that, accordingly, Emisphere required MHR’s consent to the execution of the GLP-1 License Agreement and the Insulin License Agreement, and requires MHR’s consent to the
execution of GLP-1 Amendment No. 3 and the Expansion License Agreement. In reliance on this Agreement, MHR hereby consents to Emisphere entering into GLP-1 Amendment No. 3 and the Expansion License Agreement. 

6. Amendments to the Novo Nordisk Agreement. With respect to each Novo Nordisk Agreement and on a Novo Nordisk
Agreement-by-Novo Nordisk Agreement basis, each of Emisphere and Novo Nordisk hereby agree that any modification or amendment to any Novo Nordisk Agreement that could adversely affect MHR’s rights and interests in Emisphere under the Investment
Agreements (including Section 6.5 of the Pledge and Security Agreement) shall require the prior written consent of MHR, which consent shall not be unreasonably withheld or delayed (it is further agreed that MHR’s determination not to give
such consent shall be deemed reasonable if made in good faith); provided, that if MHR determines not to grant such consent, MHR shall give notice to Novo Nordisk and Emisphere of such determination and, for a period commencing with the delivery of
such notice and ending three (3) business days thereafter, the parties will discuss the proposed modification or amendment to the applicable Novo Nordisk Agreement in good faith to attempt to resolve their differences and agree upon a mutually
acceptable amendment or modification. Following the end of such period of three (3) business days, MHR will give Novo Nordisk and Emisphere notice of its final determination of whether to grant its consent to any then proposed amendment or
modification); provided, however, that the selection of additional Program Carriers (as defined in the Novo Nordisk Agreements) in accordance with Section 2 of the relevant Novo Nordisk Agreement or update of the Licensed Patents listed in the
respective Exhibits shall not be deemed to be a modification or an amendment for purposes of this Section 6. 
 7.
Investment Agreements Unchanged; No Reliance. (a) Emisphere agrees and acknowledges that except as expressly provided herein, the Investment Agreements are unmodified in any way and remain in full force and effect. Except as
expressly provided herein, each of MHR and Emisphere agree and acknowledge, each for itself, severally and not jointly, that execution of this Agreement by MHR or Emisphere, as applicable, does not and shall not constitute a waiver of any rights or
remedies to which MHR or Emisphere, as applicable, is entitled pursuant to the Investment Agreements, nor, except as expressly provided herein, shall the same constitute a waiver of any default or event of default (including any Event of Default as
defined in any of the Investment Agreements) with respect to the Investment Agreements.  
 (b) Novo Nordisk hereby acknowledges and
agrees that it does not and shall not rely on this Agreement or the MHR License Agreement or any portion hereof or thereof, except for rights that are expressly provided to Novo Nordisk herein or in the MHR License Agreement, in order to assert any
waiver in connection with Institutional Partners IIA’s Collateral (as defined in the Pledge and Security Agreement) or any of MHR’s rights under the Investment Agreements in any manner whatsoever.

10. Confidentiality. (a) Except as expressly provided in this Section 10, this Agreement and the matters set forth
herein, as well as any notices received and delivered under this Agreement (collectively, the “Confidential Information”), shall remain strictly confidential and in addition, no party to this Agreement shall, directly or indirectly,
discuss with or disclose to any third party any Confidential Information except (i) if in the advice of such party’s counsel, disclosure of such Confidential Information is necessary for such party not to be in violation of or default
under any applicable law (including, without limitation, any statute, regulation, rule, stock exchange requirement, self-regulatory body, supervisory authority, other applicable judicial or governmental order, legal process, fiduciary or similar
duties or otherwise (collectively, the “Legal Requirements”)), provided that: (A) to the extent practical and permitted under any applicable Legal Requirements, such party shall promptly notify each other party


  
 9 








 
hereto so that such other party may, at its sole cost, expense and in its sole discretion, seek any appropriate protective order and/or take any other appropriate action; provided, however, that
such notice shall not be required by MHR or its affiliates (excluding Emisphere) prior to filings made with and to the extent required or requested by the U.S. Securities and Exchange Commission (“SEC”) or other regulatory body and
(B) in the event that such protective order is not obtained, only the portion of material which, in the advice of such person’s counsel is required to be disclosed under any applicable Legal Requirements may be disclosed, and the
disclosing party shall use its good faith efforts to obtain assurance that confidential treatment will be accorded such material; (ii) if such third party has been or will be provided such information by Emisphere or MHR in connection with
considering a potential transaction relating to the Investment Agreements or Emisphere, in each case in any manner whatsoever, and such third party has entered into a confidentiality agreement with Emisphere or MHR, as applicable, on terms that are
at least as protective as those contained in this paragraph; or (iii) to the extent that the other parties hereto have provided prior written consent to such disclosure. Confidential Information shall not include any information that is in the
public domain or any Confidential Information that subsequently enters the public domain without fault on the part of the party receiving such information. Each party agrees to consult with each other party on the possible redaction of certain
provisions, schedules, exhibits and attachments to this Agreement and the Novo Nordisk Agreements that contain information which is Confidential Information in connection with any filings made by a party with the SEC (or other regulatory body) or as
otherwise required by law; provided, however, that each party may make its own final determination of its filing obligation (including without limitation the timing of such filing) and effect such filing accordingly and without any obligation to
delay such filing. The parties agree that they have complied with this Section 10 in all respects if MHR files this Agreement and the MHR License Agreement, including any exhibits hereto or thereto, without redaction with the SEC after the date
hereof. 
 (b) Notwithstanding the foregoing, MHR may disclose Confidential Information (i) to any of MHR’s affiliates, potential
investors and potential financing sources or any acquirer or potential acquirer of assets and their respective representatives who have a need to know such Confidential Information in connection with the evaluation and/or negotiation of a potential
transaction relating to the Investment Agreements or Emisphere; provided, that: (A) the person to whom such Confidential Information is disclosed has previously entered into a confidentiality agreement with Emisphere or MHR, as applicable, on
terms that are at least as protective as those contained in the preceding paragraph 10(a) and (B) any such review by such person shall be solely for purposes of evaluating a potential transaction relating to the Investment Agreements or
Emisphere; or (ii) to any of MHR’s affiliates, equity interest holders, principals, officers, directors, employees, agents and consultants who need to know such Confidential Information in their capacity as the foregoing and who are
subject to obligations of confidentiality on customary terms. 
 (c) Notwithstanding anything else to the contrary in this Agreement, each
of Novo Nordisk and Emisphere acknowledges and agrees that, subject to MHR’s agreement concerning disclosure of the Confidential Information as provided in the immediately two preceding paragraphs, MHR and its affiliates are in the business of
making investments in, and otherwise engaging in, businesses which may or may not be in competition with Novo Nordisk or Emisphere or otherwise related to its or its affiliates’ respective business and that, except to


  
 10 








 
the extent that such activities involve the disclosure of the Confidential Information that would be prohibited hereunder, this Agreement in no way limits or restricts MHR’s or its
affiliates’ ability to make such investments or engage in such businesses. Furthermore, subject to the other provisions of this Section 10, in the event that MHR exercises any of the rights provided hereunder, MHR agrees to use
commercially reasonable efforts to maintain the confidentiality of any Confidential Information. 
 11. Effectiveness and
Termination. This Agreement will come into effect upon Emisphere’s receipt of Novo Nordisk’s payment of (i) $9 million to Emisphere pursuant to Section 1.a of the GLP-1 Amendment No. 2 and (ii) $5 million to
Emisphere pursuant to Section 3.1 of the Expansion License Agreement, and shall remain in effect until the earlier of:  
 (a)
with respect to the rights and obligations of all of the parties hereto, the termination or release of all of Institutional Partners IIA’s security interest and all other rights in the Pledge and Security Agreement in and as applicable to all
of the Licensed IP, except if such release has occurred as result of a Foreclosure; 
 and 

(b) with respect to the rights and obligations of all of the parties hereto, termination of this Agreement in its entirety immediately upon
Institutional Partners IIA or one or more Foreclosure Purchaser(s), as applicable, entering into the MHR License Agreement as to all of the Licensed IP as a result of Foreclosure on all of the Licensed IP and such MHR License Agreement becoming
fully effective as set forth in Section 4(a) hereof. 
 Upon termination of this Agreement with respect to all Licensed IP as provided
in this Section 11, all rights, duties and obligations of the parties hereto shall cease to have any force or effect and the parties shall no longer be bound by, and shall not have any obligations or duties under this Agreement. 

12. Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the domestic laws
of the State of New York, without giving effect to conflicts of law or choice of law principles (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New
York. The undersigned hereby agree that any suit or proceeding arising out of or relating to this Agreement shall be had in the Federal courts in the Borough of Manhattan in The City of New York, and hereby consent to jurisdiction and venue in such
courts.  
 13. Entire Agreement, Assignment, etc. (a) This Agreement and the MHR License Agreement
contains the entire understanding and agreement of the parties hereto and supersedes all prior agreements, understandings and negotiations between the parties hereto relating to the subject matter hereof.  

(b) The invalidity or unenforceability of any of the provisions of this Agreement shall not affect the validity or enforceability of any other
provisions hereof, which shall remain in full force and effect. 

  
 11 








 (c) The benefits of this Agreement shall inure to the parties hereto and their respective
successors and assigns, and the obligations and liabilities assumed in this Agreement by the parties hereto shall be binding upon their respective successors and assigns. 

(d) Novo Nordisk agrees that it will not, directly or indirectly, assign or otherwise transfer this Agreement to any person without MHR’s
prior written consent which consent shall not be unreasonably withheld or delayed, except for simultaneous assignment or transfer of this Agreement, the Novo Nordisk Agreements and the MHR License Agreement to the same assignee or transferee which
shall not require any prior consent. For the avoidance of doubt, in the relationship between Novo Nordisk and Emisphere (in the case of Emisphere, subject to any obligations or limitations of Emisphere pursuant to any agreements to which it is a
party) the relevant Novo Nordisk Agreement shall govern ability to assign the relevant Novo Nordisk Agreement. Also for the avoidance of doubt, Novo Nordisk may elect to assign one but not another Novo Nordisk Agreement and shall be permitted
simultaneously with the transfer or assignment of the relevant Novo Nordisk Agreement to assign or transfer to the same assignee or transferee, all (but not less than all) of the rights and obligations of Novo Nordisk under this Agreement and the
MHR License Agreement with respect to the relevant Novo Nordisk Agreement pursuant to an agreement which is the same as this Agreement (whereupon the obligations of the parties under this Agreement relating to the relevant Novo Nordisk Agreement
