        damages, losses, liabilities and expenses (including, without limitation, fees and disbursements of counsel), that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of this Agreement (including as a
        result of any breach or inaccuracy of any representation, warranty or covenant herein), the other Offering Documents, or the transactions contemplated hereby or thereby, solely to the extent such Offering Documents or transactions contemplated
        thereby relate to this Agreement and the Series C Preferred Equity Offering, any use made or proposed to be made with the proceeds of the Series C Preferred Equity Offering, or any claim, litigation, investigation or proceeding relating to any of
        the foregoing, regardless of whether any Indemnified Party is a party thereto, and the Company shall reimburse each Indemnified Party upon demand for reasonable and documented fees and expenses of counsel (which, so long as there are no conflicts
        among such Indemnified Parties, shall be limited to one law firm serving as counsel for the Indemnified Parties) and other expenses incurred by it in connection with investigating, preparing to defend or defending, or providing evidence in or
        preparing to serve or serving as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing, irrespective of whether the transactions contemplated hereby are consummated, except to the extent
        such claim, damage, loss, liability, or expense is found in a Final Order to have resulted from such Indemnified Party’s bad faith, actual fraud, gross negligence, or willful misconduct.  No Indemnified Party shall have any liability (whether
        direct or indirect, in contract, tort or otherwise) to the Company for or in connection with the transactions contemplated hereby, except to the extent such liability is found in a final, non-appealable order of a court of competent jurisdiction to
        have resulted from such Indemnified Party’s bad faith, actual fraud, gross negligence or willful misconduct.  In no event, however, shall the Company or any Indemnified Party be liable on any theory of liability for any special, indirect,
        consequential or punitive damages.  Without the prior written consent of the Indemnified Parties, the Company agrees that it will not enter into any settlement of any lawsuit, claim or other proceeding arising out of this Agreement, the other
        Offering Documents, or the transactions contemplated hereby or thereby, solely to the extent such Offering Documents or transactions contemplated thereby relate to this Agreement and the Series C Preferred Equity Offering, unless such settlement
        (i) includes an explicit and unconditional release from the party bringing such lawsuit, claim or other proceeding of all Indemnified Parties and (ii) does not include a statement as to or an admission of fault, culpability, or a failure to act by
        or on behalf of any Indemnified Party.  No Indemnified Party shall be liable for any damages arising from the use by unauthorized persons of any information made available to the Indemnified Parties by the Company or any of its representatives
        through electronic, telecommunications or other information transmission systems that is intercepted by such persons.  No Indemnified Party shall settle any lawsuit, claim, or other proceeding arising out of this Agreement, the other Offering
        Documents, or the transactions contemplated hereby or thereby without the prior written consent of the Company (such consent not to be unreasonably withheld or delayed).  Notwithstanding the foregoing, an Indemnified Party shall be entitled to no
        indemnification by the Company for any claim, damage, loss, liability, or expense incurred by or asserted or awarded against such Indemnified Party for any violation of Law by such Indemnified Party.

      10.2   Arm’s Length Transaction.  The
          Company acknowledges and agrees that (i) the Series C Preferred Equity Offering and any other transactions described in this Agreement are an arm’s-length commercial transaction between the Parties and (ii) no Purchaser has assumed nor will it
          assume an advisory or fiduciary responsibility in the Company’s favor with respect to any of the transactions contemplated by this Agreement or the process leading thereto, and no Purchaser has any obligation to the Company with respect to the
          transactions contemplated by this Agreement except those obligations expressly set forth in this Agreement or the Offering Documents to which it is a party.

          warranties, covenants, agreements and obligations of the Parties shall survive the Closing as follows (each such survival period, a “Survival Period”): (i) except for Fundamental Representations and the Tax Representations, the
          representations and warranties made by each Party in this Agreement shall survive the Closing until the first anniversary of the Closing; (ii) Fundamental Representations shall survive the Closing until the fifth anniversary of the Closing, (iii)
          Tax Representations shall survive the Closing for the full period of all applicable statutes of limitations related thereto (after giving effect to any waiver or extension thereof), and (iv) the covenants, agreements, obligations and other
          undertakings of the Parties shall survive the Closing until fully performed in accordance with their terms.  All liability of the Indemnifying Parties with respect to the representations, warranties, covenants, agreements and obligations
          hereunder shall be extinguished at the end of the applicable Survival Period, except to the extent that notice of an alleged breach of such representations, warranties, covenants, agreements or obligations has been provided before such date;
          provided that if notice is given prior to the expiration of the applicable Survival Period, the claim with respect to such representation, warranty, covenant, agreement or obligation shall continue indefinitely until finally resolved.

            hereunder must be made in writing, and the failure of any Party at any time to require another Party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation.  Any

                If to the Purchasers, to the addresses set forth with respect to each such Purchaser on Exhibit G.

              


      

       

      Any of the foregoing addresses may be changed by giving notice of such change in the foregoing manner, except that notices for changes of address shall be effective only upon receipt.

       

      10.6   Headings.  The section and subsection
          headings in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

       

        

      
        26

        
          


      

      
        10.7   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 for so long as the economic or legal
            substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall
            negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to
            the greatest extent possible.

        

        
          10.8   Entire Agreement. This Agreement and the agreements and documents
              referenced herein constitute the entire agreement of the Parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, between the Parties with respect to the subject matter
              hereof.

           

            

        

      

      10.9   Successors and Assigns.  This
          Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns.  Except as set forth below, neither this Agreement nor any of the rights, interests or obligations under this Agreement
          may be assigned by either Party (whether by operation of law or otherwise) without the prior written consent of the other Party.  Notwithstanding the foregoing and subject to the restriction on transfer contained in Section 10.10, the
          rights, obligations and interests hereunder and the shares of Series C Preferred Stock purchased hereunder may be assigned, delegated or transferred, in whole or in part, by a Purchaser to (i) any Affiliate of such
          Purchaser without the consent of the Company or (ii) one or more other third parties with the consent of the Company, which consent shall not be unreasonably withheld or delayed; provided, however, that any such transferee, as a condition precedent to such transfer, becomes a Party to this Agreement and assumes the obligations of such Purchaser with respect to the transferred shares under this
          Agreement by executing an addendum substantially in the form set forth in Exhibit A (the “Addendum”) and an assumption agreement in substantially the form set forth in Exhibit B hereto (the “Assumption Agreement”)
          and deliver the same to the Company in accordance with Section 10.5, and provided, further, that (a) with respect to a transfer to an Affiliate of a
          Purchaser, such Purchaser either (i) shall have provided an adequate equity support letter or a guarantee of such Affiliate-transferee’s obligations, in form and substance reasonably acceptable to the Company or (ii) shall remain fully obligated
          to fund the Purchase Price and (b) with respect to a transfer to a third party, the Company, acting in good faith, shall have consented in writing to such transfer (which consent shall not be unreasonably withheld, conditioned or delayed) and
          shall have determined, in its reasonable discretion, after due inquiry and investigation, that such transferee is reasonably capable of fulfilling such obligations, or, absent such a determination, the proposed transferee shall have deposited
          with an agent of the Company or into an escrow account under arrangements satisfactory to the Company funds sufficient, in the reasonable determination of the Company, to satisfy such proposed transferee’s obligations.  Any transfer that is made
          in violation of the immediately preceding sentence shall be null and void ab initio, and the Company shall have the right to enforce the voiding of such transfer.

       

        

      
        27

        
          


      

      
        10.10 Limitations on Transfer of Series C Preferred Stock.  THE SERIES C PREFERRED STOCK (INCLUDING ANY SERIES C PREFERRED STOCK ISSUED IN RESPECT OF DIVIDEND PAYMENTS THEREON) SHALL NOT BE TRANSFERRED BY ANY PURCHASER TO ANY OTHER PERSON WITHOUT THE CONSENT OF THE COMPANY,
            WHICH CONSENT SHALL NOT BE UNREASONABLY WITHHELD OR DELAYED, EXCEPT THAT, SUBJECT TO SECTION 10.9, ANY PURCHASER SHALL BE ENTITLED TO TRANSFER ANY OR ALL SHARES OF ITS SERIES C PREFERRED STOCK TO ANY AFFILIATE OF ANY PURCHASER.

         

        10.11  No Third-Party Beneficiaries.  This
            Agreement shall be binding upon and inure solely to the benefit of the Parties and their respective successors and permitted assigns and, except as expressly set forth in Section 9, nothing herein, express or implied, is intended to or
            shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever.

         

          

      

      10.12  Amendment.  This Agreement may not be
          altered, amended, or modified except by a written instrument executed by or on behalf of the Company and the Purchasers.

       

      10.13  Governing Law.  This Agreement shall
          be interpreted, construed and enforced in accordance with the laws of the State of New York, without regard to the conflicts of law principles thereof.

       

      10.14  Consent to Jurisdiction.  Each of the
          Parties (a) irrevocably and unconditionally agrees that any actions, suits or proceedings, at law or equity, arising out of or relating to this Agreement or any agreements or transactions contemplated hereby shall be heard and determined by the
          federal or state courts located in New York County in the State of New York; (b) irrevocably submits to the jurisdiction of such courts in any such action, suit or proceeding; (c) consents that any such action, suit or proceeding may be brought
          in such courts and waives any objection that such Party may now or hereafter have to the venue or jurisdiction of such courts or that such action or proceeding was brought in an inconvenient forum; and (d) agrees that service of process in any
          such action, suit or proceeding may be effected by providing a copy thereof by any of the methods of delivery permitted by Section 10.5 to such Party at its address as provided in Section 10.5 (provided that nothing herein shall
          affect the right to effect service of process in any other manner permitted by Law).

       

      10.15 Waiver of Jury Trial.  EACH OF THE
          PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE
          TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY).  EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
          SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS, AS APPLICABLE, BY, AMONG
          OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.14.

       

        

      
        28

        
          


      

      
        10.16  Currency.  Unless otherwise
            specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean United States (U.S.) dollars and all payments hereunder shall be made in United States dollars.

         

        10.17 Counterparts.  This Agreement may be
            executed and delivered (including by facsimile or electronic transmission) in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken
            together shall constitute one and the same agreement.  Signatures of the Parties transmitted by electronic mail shall be deemed to be their original signatures for all purposes.

         

      

      10.18  Specific Performance.  Each
          Party acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions contemplated by this Agreement, the other Party would not have an adequate remedy at law for money damages in the event that this
          Agreement has not been performed in accordance with its terms, and therefore agrees that the other Party shall be entitled to specific performance and injunctive or other equitable relief, without the necessity of proving the inadequacy of
          monetary damages as a remedy.

       

      10.19 Waiver of Consequential Damages. 
          Notwithstanding any provision in this Agreement to the contrary, in no event shall any Party or its Affiliates, or their respective managers, members, shareholders or representatives, be liable hereunder at any time for punitive, incidental,
          consequential special or indirect damages, including loss of future profits, revenue or income, or loss of business reputation of any other Party or any of its Affiliates, whether in contract, tort (including negligence), strict liability or
          otherwise, and each Party hereby expressly releases each other Party, its Affiliates, and their respective managers, members, shareholders, partners, consultants, representatives, successors and assigns therefrom.

       

      10.20 Purchaser Obligations.  The Parties hereby agree and acknowledge that (a) all obligations of the Purchasers hereunder, including with respect to each
        Purchaser’s compliance with all applicable covenants and the making by each Purchaser of the representations and warranties set forth in Section 4, are several and not joint and (b) no Purchaser shall have any obligation or liability of any
        kind to the Company or to any other Person in respect of any breach or noncompliance with respect to this Agreement by any other Purchaser.

       

      10.21  Rules of Construction.  The Parties
          and their respective legal counsel participated in the preparation of this Agreement, and therefore, this Agreement shall be construed neither against nor in favor of any of the Parties, but rather in accordance with the fair meaning thereof. All
          definitions set forth in this Agreement are deemed applicable whether the words defined are used in this Agreement in the singular or in the plural, and correlative forms of defined terms have corresponding meanings.  The term “including” is not
          limiting and means “including without limitation.”  The term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder” and similar terms in this
          Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement.  Section, subsection, clause, schedule, annex and exhibit references are to this Agreement unless otherwise specified.  Any reference to this
          Agreement shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, and supplements thereto and thereof, as applicable.  Whenever the context may require, any pronoun includes the
          corresponding masculine, feminine and neuter forms.
