further,  however, that if Sellers or the Additional Signatories become aware of

person or entity with  respect to the voting of, any units (other than the Units
beneficially  owned by Sellers  immediately after the Closing) or other interest

by its severance here from.

     7.10 PURCHASER OBLIGATION.

     (a)  Purchaser  agrees to  indemnify  and hold  Sellers and the  Additional
Signatories  and  their  Affiliates  and  each  of  their  respective  officers,
directors,  partners,  managers  and  employees  (each,  a  "Seller  Indemnified
Person") harmless from and against any and all liabilities, obligations, losses,
damages,  penalties,  actions,  judgments,  suits, costs, charges,  expenses and
disbursements  (including  reasonable fees and expenses of counsel) which may at
any time be  imposed  on,  incurred  by or  asserted  against  any  such  Seller
Indemnified  Person, as the result of any action taken by (or failure to act of)
Purchaser  or its  Affiliates  following  the  execution  and  delivery  of this
Agreement with respect to, or associated or in connection  with, the Partnership
or Purchaser's interests therein,  including the Sale Units (provided,  that for
avoidance of doubt,  such  obligation  of  Purchaser  shall not arise out of the
entry of the  parties  into  this  Agreement  or any  breach by  Sellers  or any
Additional Signatory of any of their representations,  warranties,  covenants or
agreements hereunder).

     (b) If a third  party  commences  any action or makes any demand  against a
Seller Indemnified  Person,  such Seller Indemnified Person will promptly notify
Purchaser in writing of such action or demand;  provided that any failure of any
Seller Indemnified Person to give such notice shall not relieve Purchaser of its
obligations  under this  SECTION  7.10,  except to the extent that  Purchaser is
actually prejudiced by such failure to give notice.  Purchaser shall, at its own
expense,  defend any action for which such Seller Indemnified Person is entitled
to  indemnification  hereunder  and shall be  entitled to control the defense of
such  action  with  counsel  (which  counsel  shall be chosen by  Purchaser  and
reasonably  acceptable to Sellers) who shall jointly represent Purchaser and its
Affiliates and such Seller Indemnified Person; provided that in the event that a
Seller  Indemnified  Person  desires to  participate in such action with counsel
selected by such Seller Indemnified  Person,  such Seller Indemnified Person may
do so at its sole cost and expense;  provided further,  however, that if counsel
chosen by Purchaser cannot represent both Purchaser and such Seller  Indemnified
Person due to a disparity  in the defenses  available  to Purchaser  and to such
Seller  Indemnified   Person,  or  other  conflict  of  interest,   such  Seller
Indemnified  Person may  participate  in such  action  with  counsel  reasonably
selected by such Indemnified Person at Purchaser's cost and expense.

     (c)  Purchaser  shall have the right to settle any  action,  so long as any
such  settlement  results in a full  release to all Seller  Indemnified  Persons
subject to such action with respect to the matters asserted therein.

     (d) In the event that any Seller  Indemnified  Person brings a legal action
against Purchaser in order to enforce its right to such  indemnification,  if it
is ultimately determined by a final non-appealable order of a court of competent
jurisdiction  that:  (i)  such  Seller  Indemnified  Person  is so  entitled  to
indemnification,  then such Seller Indemnified Person asserting such claim shall
also be entitled to recover the reasonable cost and expense of counsel  incurred
in asserting such claim and bringing such action against Purchaser; or (ii) such
Seller Indemnified Person has not prevailed in any such action, then such Seller
Indemnified  Person shall pay to Purchaser  the  reasonable  cost and expense of
counsel incurred by Purchaser and its Affiliates in defending such claim.

     7.11 FURTHER ASSURANCES.  Sellers shall execute and deliver, or cause to be
executed and delivered,  to Purchaser such documents and  agreements,  and shall
take or cause to be taken such  actions,  as Purchaser  may,  from time to time,
request to carry out the terms and conditions of this Agreement.  In addition to
the foregoing and not in limitation  thereof,  each Seller hereby agrees to take
such action and execute any transfer application or other documents (at the sole
cost and expense of Purchaser)  as may be  reasonably  requested by Purchaser to
complete  the  transfer  of the Sale  Units  contemplated  herein  and to permit
Purchaser to seek to become a substituted limited partner in the Partnership.

     7.12 LIABILITY. Each Seller shall, each individually and on its own behalf,
be liable with respect to all losses, costs, damages, judgments, suits, charges,
expenses and disbursements  (including  reasonable fees and expenses of counsel)
("Losses") incurred or suffered by Purchaser or its Affiliates as a result of or
arising out of a breach by any Seller under this  Agreement,  and in  particular
shall be liable for all Losses,  of whatever nature,  resulting from a breach by
Sellers  of  the  terms  of  Article  VI  (Standstill)  hereof.  The  Additional
Signatories  shall,  each  individually  and on his own  behalf,  be liable with
respect to all Losses  incurred or suffered by Purchaser or its  Affiliates as a
result of or arising out of a breach by such  Additional  Signatory of the terms
of  Article VI  (Standstill)  hereof.  Other than as set forth in the  preceding
sentence, the Additional Signatories shall have no personal liability hereunder,
unless such Additional Signatory shall have intentionally and knowingly caused a
Seller to violate its  obligations  hereunder.  Notwithstanding  anything to the
contrary  set forth in this  Agreement,  neither  any Seller nor any  Additional
Signatory  shall be liable under  Article VI for any action taken (or failure to
take any action) by their respective  Associates (as defined in the Poison Pill)
unless (i) such Seller or such  Additional  Signatory,  as the case may be, knew
that such Associate was taking actions in violation of this Agreement;  and (ii)
such  Seller  or  such  Additional  Signatory,  as the  case  may be (A) had the
opportunity  to prevent such  Associate from taking such actions in violation of
this  Agreement and (B) did not use such  opportunity  to prevent such Associate
from taking such action in violation of this Agreement.
