performance by Wexford of its Management Duties hereunder, the
Company shall provide written notice to Wexford of such failure
to perform. Within ten (10) days after receipt of such notice,
Wexford shall provide written notice to the Company that either
(i) Wexford has commenced to perform such action and will
diligently pursue such action to completion or (ii) Wexford
reasonably believes that the action should not be performed, in
which event the decision as to whether or not to take the action

unreasonably falls to complete the required actions within 25
days after receipt of the written notice from the Company (either
of such events being referred to herein as an "Section 2.9
Default"), the Company may terminate this Agreement for Cause.


                           ARTICLE III

                         Management Fee

     3.1  Management Fee.  As full compensation for the services
contemplated to be performed by Wexford during the term of this
Agreement, the Company shall pay Wexford the Asset Liquidation
Fee.  The Asset Liquidation Fee payable by the Company with
respect to a Liquidating Asset shall be paid on the closing of
the sale of such Liquidating Asset. if; during the Term of this
Agreement, the Board of Directors elects for any reason to
withdraw from sale a Liquidating Asset or otherwise takes an
action which materially affects the ability to sell any
Liquidating Asset at or above the Net Sales Price set forth on
Exhibit 3.1 hereto, the Company shall promptly pay to Wexford an
Asset Liquidation Fee as if such Liquidating Asset had been sold
at the Net Sales Price set forth on Exhibit 3.1 hereto [To come,
but not to be disclosed to the public to ensure that the parties'
assumed values of the Liquidating Assets are not made public and
therefore do not inhibit the parties' abilities to sell such
assets to third parties for the highest possible purchase
prices]. Notwithstanding anything to the contrary in this
Agreement, the aggregate Asset Liquidation Fees payable to
Wexford hereunder shall in no event exceed $1,500,000, provided
that, the payment by the Company to Wexford of such maximum Asset
Liquidation Fees of $1,500,000 shall not excuse Wexford from its
obligation to perform the Management Duties for the duration of
the term of this Agreement, which may include the further sale of
Liquidating Assets with respect to which no Asset Liquidation Fee
will thereafter be payable.  If Wexford falls to continue to

                                5

<PAGE>

perform such duties, it shall be liable to the Company for
liquidated damages calculated as Asset Liquidation Fee of the Net
Sales Price set forth on Exhibit 3.1 hereto with respect to those
Liquidating Assets with respect to which Wexford shall have filed
to perform such Management Duties.

     3.2  Effect of Termination for Cause. In the event of a
Termination for Cause, Wexford shall be liable to the Company for
breach of contract damages arising out of the occurrence of the
event that gave rise to the Termination for Cause. In no event
shall Wexford be liable for consequential damages.


                            ARTICLE W

by the Company at any time immediately upon notice to Wexford

whatsoever including, without limitation, reasonable legal fees
which the Indemnitees may incur in connection with their status
as such, other than costs, expenses, or disbursements of any kind
or nature whatsoever arising from the willful misconduct or the
gross negligence of such Indemnitee, if the Indemnitee acted in
good faith and in a manner it reasonably believed to be in, or
not opposed to, the best interests of the Company and, with
respect to any criminal proceeding, had no reasonable cause to
believe its conduct was unlawful.
