    INDEMNIFICATION

    


    7.1      Indemnification of Marketing
Agent. The General Partner agrees to indemnify, defend and hold harmless
the Marketing Agent, its partners, stockholders, members, directors, officers
and employees of the foregoing, 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 Marketing Agent
or 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:

     

    
      
        
        

      

      
        15

        
          

        

      

      
        
        

      

    

     

    
      	
               
      

            	
              (a)

            	
              any
      untrue statement or alleged untrue statement of a material fact contained
      in the Registration Statement (or in the Registration Statement as amended
      or supplement) or in a Prospectus (the term Prospectus for the purpose of
      this Section 7 being deemed to include the Prospectus and the Prospectus
      as amended or supplemented), or arises out of or is based upon any
      omission or alleged omission to state a material fact required to be
      stated in either such Registration Statement or such Prospectus or
      necessary to make the statements made therein not misleading, except
      insofar as any 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 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 in
      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.

    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.

    9.1      Confidentiality.

    


    
      	
               
      

            	
              (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.

              (b)

            	
              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.

              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
      other media containing any such Confidential
  Information.

    SECTION
10

    MISCELLANEOUS

    


    10.1     No Third Party Beneficiaries.
This Agreement shall not confer any rights or remedies upon any Person other
than the parties hereto, the indemnities referred to in this Agreement and their
respective successors and assigns.

    


    10.2     Entire Agreement. This
Agreement (including any schedules and exhibits attached hereto and thereto)
contains all of the agreements among the parties hereto and thereto with respect
to the transactions contemplated hereby and thereby and supersedes all prior
agreements or understandings, whether written or oral, among the parties with
respect thereto.

    


    10.3     Amendment and Modification.
This Agreement may be amended, modified or supplemented only by a written
instrument executed by all the parties.

    


    10.4     Successors and Assigns;
Assignment. All the terms and provisions of this Agreement shall be
binding upon and inure to the benefit of the parties and their respective
successors and permitted assigns. This Agreement shall not be assigned by any
party without the prior written consent of the other parties and any assignment
without such consent shall be null and void.

    


    10.5     Waiver of Compliance. Except
as otherwise provided in this Agreement, any failure of any of the parties to
comply with any obligation, covenant, agreement or condition herein may be
waived by the party entitled to the benefits thereof only by a written
instrument signed by the party granting such waiver, but any such waiver, or the
failure to insist upon strict compliance with any obligation, covenant,
agreement or condition herein, shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure or breach.

    


    10.6     Severability. The parties
hereto desire that the provisions of this Agreement be enforced to the fullest
extent permissible under the Law and public policies applied in each
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.

    


    10.7     Notices. All notices, waivers,

be deemed to be sufficient if delivered Personally, by facsimile (and, if sent

              (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.

      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 State
      of New York and hereby irrevocably consents and submits to the
      non-exclusive jurisdiction of each such court in Personam, generally 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 any
      court of the State of New York.

            


    

    


    The
provisions of this Section 10.8 shall survive any termination of this Agreement,
in whole or in part.

    10.9     No Partnership. Nothing in
this Agreement is intended to, or will be construed to constitute the General
Partner or the Fund, on the one hand, and the Marketing Agent, on the other
hand, as partners or joint venturers; it being intended that the relationship
between them will at all times be that of independent contractors.

    


    10.10   Force Majeure. Neither party
will be liable to any other party for any delay or failure to perform its
obligations under this Agreement (except for the payment of money) if such delay
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 enemy
due to war, the outbreak or escalation of hostilities, riot, fire, flood, civil
commotion, insurrection, severe or adverse weather conditions, power failure or
computer or communications line failure.

    


    10.11   Interpretation. The article
and section headings contained in this Agreement are solely for the purpose of
reference, are not part of the agreement of the parties and shall not in any way
affect the meaning or interpretation of this Agreement.

    


    10.12   No Strict Construction. The

parties to express their mutual intent, and no rule of strict construction will
be applied against any party.

    


    10.13   Counterparts; Facsimile
Signatures. This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original but all of which together shall
constitute one and the same instrument.  Facsimile counterpart
signatures to this Agreement shall be acceptable and binding.
