-------------------------------------

Guarantor hereby covenants and agrees that from the date of this
Agreement, Guarantor shall faithfully observe and fulfill, and Guarantor shall
cause to be fulfilled and observed, each and all of the following covenants
until all amounts due under the Senior Secured Notes and the Indenture shall
have been repaid.

Section 4.1. Events of Loss. If any Event of Loss or Event of Eminent
--------------
is $5.0 million or less, and if, Domain occurs and the cost of repairing,
restoring, replacing or rebuilding (collectively, "Reconstructing") in the
reasonable judgment of the managing partner of the Guarantor, to Reconstruct
would be prudent and consistent with the Guarantor's obligations to maintain
such Project, then the Guarantor shall, at its own expense and whether or not
such damage, destruction or loss is covered by an insurance policy, with
reasonable promptness, Reconstruct the same. If there are Loss Proceeds or
Eminent Domain Proceeds (from insurance or otherwise) available as a result of
such damage, destruction or loss in the amount of $5.0 million or less, then
said Loss Proceeds or Eminent Domain Proceeds shall be available to the
Guarantor for application pursuant to Section 3.10 of the Depositary Agreement.

If an Event of Loss or an Event of Eminent Domain occurs and the Loss
Proceeds or Eminent Domain Proceeds are greater than $5.0 million but less than
the total amount outstanding under the Partnership Note (the "Partnership Note
----------------
Balance") the Guarantor shall have the option to Reconstruct the Project, or any
-------
part thereof, upon the satisfaction of certain conditions outlined in Section
3.10 of the Depositary Agreement. If the Guarantor fails to exercise such
option, the Guarantor shall apply the Loss Proceeds or Eminent Domain Proceeds
to prepay amounts outstanding under the Partnership Note as described in Section
2.5(b) of this Agreement.

If an Event of Loss or an Event of Eminent Domain occurs and the Loss
Proceeds or Eminent Domain Proceeds are equal to or exceed the Partnership Note
Balance, then the Guarantor shall apply those Loss Proceeds or Eminent Domain
Proceeds to prepay amounts outstanding under the Partnership Note, as described
in Section 2.5(b) of this Agreement unless the Guarantor obtains a determination
form the Rating Agencies that the credit rating of the senior secured notes that
had been in effect immediately before the Event of Loss or Event of Eminent
Domain will not be adversely affected by applying those Loss Proceeds or Eminent
Domain Proceeds to Reconstruction of the Project.

Section 4.2. Reporting Requirements. Guarantor shall provide to
----------------------
Funding Corporation (a) all quarterly and annual financial information that

with respect to the annual information only, a report thereon by the Guarantor's
independent certified public accountants, (b) all current reports that would be
required to be filed with the SEC on Form 8-K if Guarantor was required to file
such reports, within the time periods specified in the SEC's rules and
regulations, (c) all other information in respect of Guarantor requested by
Funding Corporation to enable Funding Corporation to meet its obligations under
