Action related thereto) that may be beneficially owned by such Consenting Lender that are not held through accounts or funds managed by such investment manager. 

(c) No Reliance And No Duty To Disclose. Each of the Parties hereto, on behalf of itself and its Related Parties, in any capacity,
agrees and acknowledges that (a) except as expressly provided in this Agreement, no other Party hereto or any other Released Party, in any capacity, has warranted or otherwise made any representations to it or any of its Related Parties
concerning any Restructuring Claim (including any representation concerning the existence, nonexistence, validity or invalidity of any Restructuring Claim) and no Releasing Party has relied on any Released Party in providing the releases and
covenants not to sue in this Article 2, (b) the validity and effectiveness of the foregoing releases and covenants not to sue in this Article 2 do not depend in any way on any such representations or warranties or the accuracy, completeness or
validity thereof, (c) no other Party hereto or any other Released Party, in any capacity, has any duty to disclose or provide any facts or documents (whether material or immaterial, known or unknown, suspected or unsuspected) to it or any other
Releasing Party, including any facts or documents which, if known by any Releasor, might have caused such Releasor or any Party hereto to which such Releasing Party is affiliated not to execute and deliver this Release and/or any of the other
Definitive Documents, and (d) subject to Section 2(b), each such release and covenant not to sue shall remain in full force and effect even if any facts or documents (whether material or immaterial, known or unknown,
suspected or unsuspected, foreseen or unforeseen) were not disclosed or provided (whether intentionally, unintentionally, or otherwise) by any Released Party to any Releasing Party, which facts or documents, if known by such Releasing Party, might
have caused such Releasing Party or any Party hereto to which such Releasing Party is affiliated not to execute and deliver this Release and/or any of the other Definitive Documents. Nothing contained herein is intended to impair or otherwise
derogate from any of the representations, warranties, or covenants expressly set forth in this Agreement or in the other Definitive Documents. 

(d) Waiver of Statutory Limitations on Release. Except as otherwise set forth herein or as prohibited by law or statute, it is the
intention of each Party to extinguish all released Causes of Action and consistent with such intention, each Party hereby expressly waives his, her, or its rights to the fullest extent permitted by law, to any benefits of the provisions of
Section 1542 of the California Civil Code or any other similar state law, federal law, or principle of common law, which may have the effect of limiting the releases set forth herein, which reads in full as follow: 

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE
TIME OF EXECUTING THE RELEASE WHICH, IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR. 
 (e) Each
Party acknowledges that he, she, or it may discover facts in addition to or different from those now known or believed to be true with respect to the subject matter of the releases granted herein, but acknowledges that it is his, her, or its
intention to fully, finally, and forever settle, release and discharge any and all Restructuring Claims hereby known or unknown, suspected or unsuspected, which do or do not exist, or heretofore existed, and without regard to the subsequent
discovery or existence of such additional or different facts. 

  
 4 

 (f) Notwithstanding anything to the contrary herein, nothing in this Release shall prohibit
or impede any Party hereto from communicating, cooperating or filing a complaint with any U.S. federal, state or local law enforcement branch, agency or entity (collectively a “Governmental Entity”) with respect to any possible
violations of any U.S. federal, state or local law or regulation, or otherwise making disclosures relating thereto to any such Governmental Entity, in each case, that are protected under the whistleblower provisions of any provision of such law or
regulation, provided that in each case (i) such communications and disclosures are consistent with applicable law and made in good faith and (ii) the information subject to such disclosure was not obtained by a Party through a
communication that was subject to attorney-client privilege, unless disclosure of that information would otherwise be permitted by an attorney pursuant to 17 C.F.R. 205.3(d), applicable state attorney conduct rules, or otherwise. 

(g) Notwithstanding anything to the contrary set forth herein, each of the Parties hereby expressly reserves all of its defenses to any Cause
of Actions that may be asserted against any of them by any other Party, including, but not limited to, any defense that this Release releases any asserted Restructuring Claim. 

3. Released Party Representations, Warranties and Covenants. 

Each Released Party party hereto represents and warrants, after due inquiry and reasonable investigation, that, as of the Effective Time,
neither it, nor any of its directors or officers is aware of any current or potential indemnification claims or other Causes of Action against it or any of them, or any facts or circumstances that would give rise to any potential indemnification
claim or other Cause of Action. 
 4. Miscellaneous. 

(a) Successors and Assigns. All covenants, rights, obligations and other agreements contained in this Release by, through or on behalf
of any of the Parties bind and inure to the benefit of such Party and its respective successors and permitted assigns, whether so expressed or not. This Release, and the rights and obligations of each Party, shall not be assigned by such Party
without prior written consent of the other Parties. 
 (b) Entire Agreement. This Release contains the entire understanding of the
Parties with respect to the releases set forth herein. 
 (c) Effectiveness; Amendments. This Release (including the releases provided

delivered this Release and (ii) the Closing Date (as defined in the Strict Foreclosure Agreement) has occurred (the “Effective Time”). For the avoidance of doubt, prior to the Effective Time, (x) none of the provisions of
this Release shall be valid, binding or enforceable and (y) no Person shall be permitted to rely on, or shall have any rights or remedies with respect to, this Release. No modification, amendment or supplement to, or waiver, forbearance or
consent under or with respect to, this Release (including any provision hereof, or any rights or obligations hereunder or arising in connection herewith) shall be effective without the prior written consent of each Party hereto. 

  
 5 

 (d) Severability. Any provision of this Release that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to
the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 
 (e)
Counterparts. This Release may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by
less than all, but together signed by all the Parties. This Release may be executed and delivered by facsimile, email, or otherwise and such signature is deemed binding for all purposes hereof, without delivery of an original signature being
thereafter required. 
 (f) Headings. The headings of the sections and subsections of this Release are inserted for convenience only
and shall not affect the interpretation hereof. 
 (g) Governing Law. This Release shall be construed and enforced in accordance with,
and the rights of the Parties shall be governed by, the laws of the State of New York excluding choice-of-law principles of the laws of the State of New York that would
permit the application of the laws of a jurisdiction other than the State of New York. 
 (h) Jurisdiction and Process; Waiver of Jury
Trial. 
  

	 	i.	 Each Party irrevocably and unconditionally agrees that it will not commence any action, litigation, or
proceedings of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against any other Party that in any way relates to this Release in any forum other than the courts of the State of New York sitting in New
York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and the Parties irrevocably and unconditionally submit to the jurisdiction of such courts and agree that all claims
in respect of any such action, litigation or proceeding relating to this Release may be heard and determined in such New York State Court or, to the fullest extent permitted by applicable law, in such federal court. To the fullest extent permitted
by applicable law, in connection with any such action, litigation or proceeding relating to this Release, the Parties irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that they are not subject to the
jurisdiction of any such court, any objection that they may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such
court has been brought in an inconvenient forum. 

  
 6 

	 	ii.	 The Parties hereby waive trial by jury in any action brought on or with respect to this Release, or any other
documents executed in connection herewith. 

 (i) Specific Performance. Each Party recognizes and acknowledges that
a breach by such Party of any of its covenants or agreements contained in this Release may cause the other Parties to sustain damages for which such other Parties may not have an adequate remedy at law for money damages, and, therefore, such Party
agrees that, in the event of any such breach by it, the other Parties may be able to seek the remedy of specific performance of one or more such breached covenants and agreements and injunctive and certain other equitable relief in addition to any
other remedy to which such other Parties may be entitled, at law or in equity. 
 (j) Remedies Cumulative. All rights, powers and
remedies provided under this Release or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise of any right, power or remedy thereof by any Party shall not preclude the simultaneous or
later exercise of any other such right, power or remedy by such Party. 
 (k) No Waiver. The failure of any Party to exercise any
right, power, or remedy provided under this Release or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other Party with its obligations hereunder, and any custom or practice of the Parties at variance
with the terms hereof, shall not constitute a waiver by such Party of its right to exercise any such or other right, power, or remedy or to demand such compliance. 

(l) Several, Not Joint, Obligations. The agreements and obligations of each of the Parties under this Release are, in all respects,
several and not joint. 
 (m) Parties’ Use of Legal Counsel And Construction Of Release. Each Party hereby acknowledges that it
has had the opportunity to be advised by its own legal counsel in connection with the negotiation, drafting, execution, and delivery and consummation of this Release. The Parties agree and acknowledge that the normal rule of construction to the
effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Release or any amendments, exhibits or schedules hereto. Each Party has entered into this Release freely and voluntarily,
without coercion, duress, distress or under influence by any other Persons or its respective shareholders, directors, officers, partners, agents or employees. Each of the Parties hereby acknowledges that (i) it has read this Release and knows
its contents, (ii) it understands the terms and consequences of this Release, and (iii) the terms of this Release are fair and reasonable. 

(n) Compromise; No Admission of Wrongdoing. This Release is entered into in compromise of disputed claims and defenses constituting the
Restructuring Claims. No act or agreement in furtherance of the Release shall be construed in any way as an admission of fault, wrongdoing, or liability on the part of any Party and, for the avoidance of doubt, notwithstanding anything to the
contrary, each Party hereby denies (and shall be deemed to deny) any fault, wrongdoing, or liability for any and all claims and Causes of Action, and no settlement of any Causes of Action against any such Party shall be permitted without such
Party’s prior written consent. Neither this Release, nor any of its terms, shall be offered by any of the Parties in evidence in any arbitral, civil, criminal, administrative, or other proceeding as a concession or admission of fault,
wrongdoing or liability; provided, that nothing in this section shall prevent any Party from using or offering this Release in evidence in any proceeding to enforce and/or effectuate the terms of this Release. 

  
 7 

 (o) No Third Party Rights. The provisions of this Release are for the benefit of the
Parties, and unless otherwise provided herein, no other Person shall have any right or claim against any Party by reason of this Release or any provision hereof or be entitled to enforce any provision of this Release. Notwithstanding the foregoing,
for the avoidance of doubt, the Released Parties may enforce the provisions of this Release, as set forth herein.
