                out
                of or is based upon any untrue statement or alleged untrue statement
                of a
                material fact contained in and in conformity with information concerning
                the Marketing Agent furnished in writing by or on behalf of the Marketing
                Agent to the General Partner expressly for use in such Registration
                Statement or such Prospectus;

            


    

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    
      	 	
              (b)

            	
              any
                untrue statement or alleged untrue statement of a material fact or
                breach
                by the General Partner of any representation or warranty contained

                Section 2 hereof or in any certificate delivered by the General Partner
                pursuant to paragraph (o) of Section 5.1
                hereof;

            


    

    


    
      	 	
              (c)

            	
              the
                failure by the General Partner to perform when and as required any
                agreement or covenant contained
                herein;

            


    

    


    
      	 	
              (d)

            	
              any
                untrue statement of any material fact contained in any audio or visual
                materials provided by the General Partner or based upon written
                information furnished by or on behalf of the General Partner including,
                without limitation, slides, videos, films or tape recordings used
                in
                connection with the marketing of the
                Units;

            


    

    


    
      	 	
              (e)

            	
              the
                Marketing Agent’s performance of its duties under this Agreement except in
                the case of this clause (e), for any loss, damage, expense, liability
                or
                claim resulting from the gross negligence or willful misconduct of
                the
                Marketing Agent; provided, however, that the indemnity agreement
                contained
                in clause (a) above with respect to any amended Preliminary Prospectus
                shall not inure to the benefit of the Marketing Agent (or to the
                benefit
                of any Person controlling the Marketing Agent) from whom the Person
                asserting any such loss, damage, expense, liability or claim purchased
                the
                Units which is the subject thereof if the Prospectus corrected any
                such
                alleged untrue statement or omission in any case where the Marketing
                Agent
                was required to send or give a copy of the Prospectus to such Person
                by
                the 1933 Act, the General Partner had notified the Marketing Agent
                of the
                amendment or supplement prior to the sending of the written confirmation
                of sale and the Marketing Agent failed to send or give a copy of
                the
                Prospectus to such Person, unless the failure is the result of
                noncompliance by the General Partner with paragraph (c) of Section
                5.1
                hereof.

            


    

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    In
      no
      case is the indemnity of the General Partner in favor of the Marketing Agent
      and
      such other Persons as are specified in this Section 7.1 to be deemed to protect
      the Marketing Agent and such Persons against any liability to the General
      Partner or the Fund to which the Marketing Agent would otherwise be subject
      by
      reason of willful misfeasance, bad faith or gross negligence in the performance
      of its duties or by reason of its reckless disregard of its obligations and
      duties under this Agreement.

    


    If
      any
      action, suit or proceeding (each, a “Proceeding”) is brought against the
      Marketing Agent or any such Person in respect of which indemnity may be sought
      against the General Partner pursuant to the foregoing paragraph, the Marketing
      Agent or such Person shall promptly notify the General Partner in writing of
      the
      institution of such Proceeding and the General Partner shall assume the defense
      of such Proceeding, including the employment of counsel reasonably satisfactory
      to such indemnified party and payment of all fees and expenses; provided,
      however, that the omission to so notify the General Partner shall not relieve
      the General Partner from any liability which it may have to the Marketing Agent
      or any such Person except to the extent that it has been materially prejudiced
      by such failure and has not otherwise learned of such Proceeding. The Marketing
      Agent or such Person shall have the right to employ its or their own counsel
      in
      any such case, but the fees and expenses of such counsel shall be at the expense
      of the Marketing Agent or of such Person unless the employment of such counsel
      shall have been authorized in writing by the General Partner in connection
      with
      the defense of such Proceeding or the General Partner shall not have, within
      a
      reasonable period of time in light of the circumstances, employed counsel to
      have charge of the defense of such Proceeding or such indemnified party or
      parties shall have reasonably concluded that there may be defenses available
      to
      it or them which are different from, additional to or in conflict with those
      available to the General Partner (in which case the General Partner shall not
      have the right to direct the defense of such Proceeding on behalf of the
      indemnified party or parties), in any of which events such fees and expenses
      shall be borne by the General Partner and paid as incurred (it being understood,
      however, that the General Partner shall not be liable for the expenses of more
      than one separate counsel (in addition to any local counsel) in any one
      Proceeding or series of related Proceedings in the same jurisdiction
      representing the indemnified parties who are parties to such Proceeding).


    


    The
      General Partner shall not be liable for any settlement of any Proceeding
      effected without the General Partner’s written consent but if settled with the
      General Partner’s written consent, the General Partner agrees to indemnify and
      hold harmless the Marketing Agent and any such Person from and against any
      loss
      or liability by reason of such settlement. Notwithstanding the foregoing
      sentence, if at any time an indemnified party shall have requested an
      indemnifying party to reimburse the indemnified party for fees and expenses
      of
      counsel as contemplated by the second sentence of this paragraph, then the
      indemnifying party agrees that it shall be liable for any settlement of any
      Proceeding effected without its written consent if (i) such settlement is
      entered into more than 60 Business Days after receipt by such indemnifying
      party
      of the aforesaid request, (ii) such indemnifying party shall not have fully
      reimbursed the indemnified party in accordance with such request prior to the
      date of such settlement and (iii) such indemnified party shall have given the
      indemnifying party at least 30 Business Days’ prior notice of its intention to
      settle. No indemnifying party shall, without the prior written consent of the
      indemnified party, effect any settlement of any pending or threatened Proceeding
      in respect of which any indemnified party is or could have been a party and
      indemnity could have been sought hereunder by such indemnified party, unless
      such settlement includes an unconditional release of such indemnified party
      from
      all liability on claims that are the subject matter of such Proceeding and
      does
      not include an admission of fault, culpability or a failure to act, by or on
      behalf of such indemnified party.


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    6.2 The
      Marketing Agent agrees to indemnify, defend and hold harmless each of the Fund,
      the General Partner and its partners, holders of Units, members, directors,
      officers, employees and any Person who controls the General Partner within
      the
      meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act, and
      the
      successors and assigns of all of the foregoing Persons, from and against any
      loss, damage, expense, liability or claim (including the reasonable cost of
      investigation) which the General Partner any such Person may incur under the
      1933 Act, the Exchange Act, the common law or otherwise, insofar as such loss,
      damage, expense, liability or claim arises out of or is based upon any untrue
      statement or alleged untrue statement of a material fact contained in and in
      conformity with information furnished in writing by or on behalf of the
      Marketing Agent to the General Partner expressly for use in the Registration
      Statement (or in the Registration Statement as amended or supplemented by any
      post-effective amendment thereof) or in a Prospectus, or arises out of or is
      based upon any omission or alleged omission to state a material fact in
      connection with such information required to be stated in such Registration
      Statement or such Prospectus or necessary to make such information not
      misleading.

    


    The
      Marketing Agent will also indemnify the General Partner as stated above insofar
      as such loss, damage, expense, liability or claim arises out of or is based
      upon
      the Marketing Agent’s performance of its duties under this Agreement, except in
      the case of any loss, damage, expense, liability or claim resulting from the
      gross negligence or willful misconduct of the General Partner. In no case is
      the
      indemnity of the Marketing Agent in favor of the General Partner to be deemed
      to
      protect the General Partner and such Persons against any liability to the
      Marketing Agent to which the General Partner would otherwise be subject by
      reason of willful misfeasance, bad faith or gross negligence in the performance
      of its duties or by reason of its reckless disregard of its obligations and
      duties under this Agreement.

    


    If
      any
      Proceeding is brought against the General Partner or any Person referred to
      in
      the preceding paragraph in respect of which indemnity may be sought against
      the
      Marketing Agent pursuant to the foregoing paragraph, the General Partner or
      such
      Person shall promptly notify the Marketing Agent in writing of the institution
      of such Proceeding and the Marketing Agent shall assume the defense of such
      Proceeding, including the employment of counsel reasonably satisfactory to
      such
      indemnified party and payment of all fees and expenses; provided, however,
      that
      the omission to so notify the Marketing Agent shall not relieve the Marketing
      Agent from any liability which it may have to the General Partner or any such
      Person except to the extent that it has been materially prejudiced by such
      failure and has not otherwise learned of such Proceeding. The General Partner
      or
      such Person shall have the right to employ their own counsel in any such case,
      but the fees and expenses of such counsel shall be at the expense of the General
      Partner or such Person unless the employment of such counsel shall have been
      authorized in writing by the Marketing Agent in connection with the defense
      of
      such Proceeding or the Marketing Agent shall not have, within a reasonable
      period of time in light of the circumstances, employed counsel to defend such
      Proceeding or such indemnified party or parties shall have reasonably concluded
      that there may be defenses available to it or them which are different from
      or
      additional to or in conflict with those available to the Marketing Agent (in
      which case the Marketing Agent shall not have the right to direct the defense
      of
      such Proceeding on behalf of the indemnified party or parties, but the Marketing
      Agent may employ counsel and participate in the defense thereof but the fees
      and
      expenses of such counsel shall be at the expense of the Marketing Agent), in
      any
      of which events such fees and expenses shall be borne by the Marketing Agent
      and
      paid as incurred (it being understood, however, that the Marketing Agent shall
      not be liable for the expenses of more than one separate counsel (in addition
      to
      any local counsel) in any one Proceeding or series of related Proceedings in
      the
      same jurisdiction representing the indemnified parties who are parties to such
      Proceeding). 

    


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    The
      Marketing Agent shall not be liable for any settlement of any such Proceeding
      effected without the written consent of the Marketing Agent but if settled
      with
      the written consent of the Marketing Agent, the Marketing Agent agrees to
      indemnify and hold harmless the General Partner and any such Person from and
      against any loss or liability by reason of such settlement. Notwithstanding
      the
      foregoing sentence, if at any time an indemnified party shall have requested
      an
      indemnifying party to reimburse the indemnified party for fees and expenses
      of
      counsel as contemplated by the second sentence of this paragraph, then the
      indemnifying party agrees that it shall be liable for any settlement of any
      Proceeding effected without its written consent if (i) such settlement is
      entered into more than 60 Business Days after receipt by such indemnifying
      party
      of the aforesaid request, (ii) such indemnifying party shall not have reimbursed
      the indemnified party in accordance with such request prior to the date of
      such
      settlement and (iii) such indemnified party shall have given the indemnifying
      party at least 30 Business Days’ prior notice of its intention to settle. No
      indemnifying party shall, without the prior written consent of the indemnified
      party, effect any settlement of any pending or threatened Proceeding in respect
      of which any indemnified party is or could have been a party and indemnity
      could
      have been sought hereunder by such indemnified party, unless such settlement
      includes an unconditional release of such indemnified party from all liability
      on claims that are the subject matter of such Proceeding.

    


    7.3 The
      indemnity agreements contained in this Section 7 and the covenants, warranties
      and representations of the General Partner contained in this Agreement shall
      remain in full force and effect regardless of any investigation made by or
      on
      behalf of the Marketing Agent, its partners, stockholders, members, directors,
      officers, employees and or any Person (including each partner, stockholder,
      member, director, officer or employee of such Person) who controls the Marketing
      Agent within the meaning of Section 15 of the 1933 Act or Section 20 of the
      Exchange Act, or by or on behalf of each of the General Partner, the Fund,
      their
      partners, stockholders, members, directors, officers, employees or any Person
      who controls the General Partner or the Fund within the meaning of Section
      15 of
      the 1933 Act or Section 20 of the Exchange Act, and shall survive any
      termination of this Agreement or the initial issuance and delivery of the Units.
      The General Partner and the Marketing Agent agree promptly to notify each other
      of the commencement of any Proceeding against it and, in the case of the General
      Partner, against any of the General Partner’s officers or directors in
      connection with the issuance and sale of the Units, or in connection with the
      Registration Statement or the Prospectus.

      8

    DURATION

    


    This
      Agreement shall become effective on the date hereof and continue for an initial
      term of one (1) year from the date of this Agreement and will include any
      renewal term of this Agreement and will last until the expiration of this
      Agreement or the earlier termination of this Agreement in accordance with its
      terms (the “Term”). This Agreement will automatically be renewed for successive
      one (1) year periods unless, no later than thirty (30) calendar days prior
      to
      the end of the then-current Term, either the Marketing Agent, on the one hand,
      or the General Partner, on the other hand, elects to terminate this Agreement
      by
      delivering written notice thereof to the other party. Notwithstanding the
      foregoing, this Agreement may be terminated by any party upon written notice
      to
      the other parties if (a) the Fund is terminated, (b) any other party becomes
      insolvent or bankrupt or files a voluntary petition, or is subject to an
      involuntary petition, in bankruptcy or attempts to or makes an assignment for
      the benefit of its creditors or consents to the appointment of a trustee or
      receiver, provided that the General Partner may not terminate this Agreement
      pursuant to this provision if the event relates to the General Partner or the
      Fund or (c) any other party willfully and materially breaches its obligations
      under this Agreement and such breach has not been cured to the reasonable
      satisfaction of the non-breaching party prior to the expiration of ninety (90)
      days after notice by the non-breaching party to the breaching party of such
      breach.

              (a)

            	
              The
                General Partner and the Marketing Agent shall during the Term and
                for one
                (1) year thereafter maintain in confidence, use only for the purposes
                provided for in this Agreement, and not disclose to any third party,
                without first obtaining the other party’s consent in writing, any and all
                Confidential Information (as defined below) such party receives from
                the
                other party; provided, however, that either party may disclose
                Confidential Information received from the other party to those of
                its
                Representatives as may be necessary for such party to carry out its
                obligations under this Agreement. 

            


    

    


    
      	 	 	
              “Confidential
                Information” shall mean all information or data of a party that is
                disclosed to or received by the other party, whether orally, visually
                or
                in writing, in any form, including, without limitation, information
                or
                data which relates to such party’s business or operations, research and
                development, marketing plans or activities, or actual or potential
                products.

              Notwithstanding
                the provisions of this Agreement to the contrary, a party shall have
                no
                liability to the other party for the disclosure or use of any Confidential
                Information of the other party if the Confidential
                Information:

            


    

    


    
      	 	 	
              (i)

            	
              is
                known to such party at the time of disclosure other than as the result
                of
                a breach of this Section 9 by such
                party;

            


    

    


    
      	 	 	
              (ii)

            	
              has
                been or becomes publicly known, other than as the result of a breach
                of
                this Section 9 by such party, or has been or is publicly disclosed
                by the
                other party;

            


    

    


    
      	 	 	
              (iii)

            	
              is
                received by such party after the date of this Agreement from a third
                party
                (unless such third party breaches an obligation of confidentiality
                to the
                other party); or

            


    

    


    
      	 	 	
              (iv)

            	
              is
                required to be disclosed by Law or similar compulsion or in connection
                with any legal proceeding, provided that such party shall promptly
                inform
                the other party in writing of such requirement and that such disclosure
                shall be limited to the extent so required and, except to the extent
                prohibited by Law, such party shall reasonably cooperate with the
                other
                party (at the expense of the other party) in seeking a protective
                order or
                other suitable confidentiality
                protections.

            


    

    


    
      	 	
              (c)

            	
              The
                parties recognize and acknowledge that a breach or threatened breach
                by a
                party of the provisions of this Section 9 may cause irreparable and
                material loss and damage to the other party which cannot be adequately
                remedied at law and that, accordingly, in addition to, and not in
                lieu of,
                any damages or other remedy to which the non-breaching party may
                be
                entitled, the issuance of an injunction or other equitable remedy
                (without
                the requirement that a bond or other security be posted) is an appropriate
                remedy for the non-breaching party for any breach or threatened breach
                of
                the obligations set forth in this Section
                9.

            


    

    


    
      	 	
              (d)

            	
              Each
                party agrees that it will use the same degree of care, but no less
                than a
                reasonable degree of care, in safeguarding the Confidential Information
                of
                the other party as it uses for its own Confidential Information of
                a
                similar nature. Each party shall promptly notify the other party
                in
                writing of any misuse, misappropriation or unauthorized disclosure
                of the
                Confidential Information of the other party which may come to such
                party’s
                attention.

            


    

    


    
      	 	
              (e)

            	
              Upon
                the termination of this Agreement, if requested in writing by a party,
                the
                other party shall, at such party’s option, promptly destroy or return to
                the party all Confidential Information received from the other party,
                all
                copies and extracts of such Confidential Information and all documents
                or

                Information.

      jurisdiction in which enforcement is sought. Accordingly, in the event that
      any
      provision of this Agreement would be held in any jurisdiction to be invalid,
      prohibited or unenforceable for any reason, such provision, as to such
      jurisdiction, shall be ineffective, without invalidating the remaining
      provisions of this Agreement or affecting the validity or enforceability of
      such
      provision in any other jurisdiction. Notwithstanding the foregoing, if such
      provision could be more narrowly drawn so as not to be invalid, prohibited
      or
      unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so
      narrowly drawn, without invalidating the remaining provisions of this Agreement
      or affecting the validity or enforceability of such provision in any other
      jurisdiction.

              (a)

            	
              All
                questions concerning the construction, interpretation and validity
                of this
                Agreement shall be governed by, and construed and enforced in accordance
                with, the domestic laws of the State of New York, without giving
                effect to
                any choice or conflict of law provision or rule (whether in 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. In
                furtherance of the foregoing, the internal law of the State of New
                York
                will control the interpretation and construction of this Agreement,
                even
                if under such jurisdiction’s choice of law or conflict of law analysis,
                the substantive law of some other jurisdiction would ordinarily or
                necessarily apply.

            


    

    


    
      	 	
              (b)

                respect
                to its obligations, liabilities or any other matter arising out of
                or in
                connection with this Agreement may be brought in the courts of the

                and
                unconditionally with respect to any action, suit or proceeding for
                itself
                and in respect of its properties, assets and revenues. Each party
                irrevocably waives any immunity to jurisdiction to which it may otherwise
                be entitled or become entitled (including sovereign immunity, immunity
                to
                pre-judgment attachment and execution) in any legal suit, action
                or
                proceeding against it arising out of or based on this Agreement or
                the
                transactions contemplated hereby or thereby which is instituted in

      or failure arises from or is due to any cause or causes beyond the reasonable
      control of the party affected which impedes, delays or aggravates any obligation
      under this Agreement, including, without limitation, acts of God, acts of any
      Governmental Entity, labor disturbances, act of terrorism or act of public
