Expense net of interest income for such period plus (B) all dividends on

in paragraphs 2(a), (b), (c), (d) and (e) hereof shall only be effective
through and including November 1, 1996, and any Event of Default that
would have existed and been continuing but for the effect of this Waiver
shall be reinstated and shall thereafter continue to constitute an Event
of Default unless further expressly waived in writing in accordance with
the Credit Agreement and the Note Agreements.

          (g)  Notwithstanding anything in the Credit Agreement to the
contrary, during the period from the date hereof to and including November
1, 1996, no Loans may be made or requested under the Credit Agreement. 
During such period, the Commitments thereunder shall only be available for
the issuance of Letters of Credit, subject to all the other provisions of
the Credit Agreement and to the extent available to be issued in

deemed to be references to this Waiver and to the Credit Agreement or the
Note Agreements, as the case may be, as amended by this Waiver.

          5.   Limited Waiver.  Except as expressly waived herein, the
Credit Agreement and each of the Note Agreements shall continue to be, and
shall remain, in full force and effect.  This Waiver shall not be deemed

other term or condition of the Credit Agreement, any other Loan Document,
any of the Note Agreements or any Senior Note or to prejudice any other
right or rights which the Lenders may now have or may have in the future
under or in connection with any thereof or any of the instruments or
agreements referred to therein, as the same may be amended from time to
time.

          6.   GOVERNING LAW.  THIS WAIVER SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK.

hereto in any number of separate counterparts and all of said counterparts
taken together shall be deemed to constitute one and the same instrument.
