property, subject to the terms and conditions of this Agreement, including any
power of an assignee to become a Limited Partner.

interests of the Partnership. Without limiting the generality of the foregoing,
the General Partner, in its discretion, may make (and if made, may revoke) the
election referred to in Section 754 of the Code, and any similar provisions

      Section 10.1. Exculpatory Provisions.

General Partner, its Affiliates, nor any of their respective officers,
directors, shareholders, partners, employees, representatives or agents nor any
officer, employee, representative or



agent of the Partnership and its Affiliates (individually, a "Covered Person"
and collectively, the "Covered Persons") shall be liable to the Partnership or
any Partner for any act or omission (in relation to the Partnership, this
Agreement, any related document or any transaction or investment contemplated
hereby or thereby) taken or omitted in good faith by a Covered Person and in the
reasonable belief that such act or omission is in or is not contrary to the best
interests of the Partnership and is within the scope of authority granted to
such Covered Person by this Agreement, provided that such act or omission does
not constitute Disabling Conduct.

            (b)   A Covered Person may rely and shall incur no liability in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, debenture,
paper, document, signature or writing reasonably believed by it to be genuine,
and may rely on a certificate signed by an officer of any Person in order to

Indemnified Persons and such other Persons as the General Partner shall
determine, against any liability that may be asserted against or expenses that
may be incurred by such Person in connection with activities of the Partnership
or such Persons, regardless of whether the Partnership would have the power to
indemnify such Person against such liability. The General Partner and the
Partnership may enter into indemnity contracts with Indemnified Persons and
adopt written procedures pursuant to which arrangements are made for the
advancement of expenses and the funding of obligations under this Section 10.2
and containing such other procedures regarding indemnification as are
appropriate. "Indemnified Persons" means the General Partner, its Affiliates and

the Certificate of Limited Partnership shall have been cancelled in the manner
required by the Act.
