         WHEREAS, Borrower desires to amend certain provisions of the Credit

conditions set forth herein;

         NOW THEREFORE, for and in consideration of the foregoing and for ten
dollars ($10.00) and other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto agree as follows:

                                   ARTICLE 1.

"MARGIN AMOUNT" are hereby added to Section 1.1 of the Credit Agreement to read
in their entirety as follows:

         "Liquid Collateral" means (i) cash or cash equivalents, which cash
         equivalents must be reasonably acceptable to Lender; (ii) stocks listed
         on the New York Stock Exchange, the American Stock Exchange or NASDAQ
         with a market capitalization of at least $500,000,000 and otherwise
         reasonably acceptable to Lender; and (iii) obligations of the United
         States of America or of agencies or authorities the principal of and
         interest on which is fully guaranteed by the United States of America;
         provided, for any such type of Collateral, Borrower shall execute and
         deliver such documentation as Lender may require in its sole discretion

         be subject to no other Liens).

         "Margin Amount" means with respect to (i) Liquid Collateral described
         in clause (i) of the definition thereof, Liquid Collateral in an amount
         not less than 100% of the amount of the requested Loan advance; (ii)

         JOURNAL or other recognized national source, multiplied by the number
         of shares of such stock(s) delivered; and in determining "value" for
         the purposes of clause (iii) hereof, Lender may use any reasonable
         valuation method it determines is appropriate, including the most
         recent closing bid price for such obligations (rather than a stated par
         amount). None of any such Liquid Collateral shall be subject to any
         Lien other than the Lien granted by Borrower in favor of Lender.

          SECTION 2.1 CONDITIONS. The amendments to the Credit Agreement set
