                                    RECITALS
                                    --------



     I.   Capitalized terms used herein which are not herein defined shall have
the meanings ascribed thereto by the Credit Agreement.

     II.  MEM Holdings, LLC ("MEM"), which is a member of Holdings and which is
                              ---
indirectly wholly owned by the Sponsors, desires to make a subordinated loan in
an original principal amount of $3,000,000 to the Borrower pursuant to a note, a
copy of which is attached hereto as Exhibit A (the "Subordinated Note").
                                                    -----------------

     III. The Borrower has requested that the definition of "Permitted Sponsor
Subordinated Debt" in the Credit Agreement be amended in its entirety in order
to permit the Borrower to incur Permitted Sponsor Subordinated Debt from MEM as
well as from the Sponsors.

     IV.  The Borrower has also requested the consent of the Requisite Lenders

Agreement. If the Subordinated Note is approved by the Requisite Lenders
pursuant to this Amendment, the loan incurred pursuant to the Subordinated Note
will constitute "Permitted Sponsor Subordinated Debt" under the Credit Agreement

     V.   The Borrower has also requested a waiver to allow it to be in
compliance with the Total Leverage Ratio and the Senior Leverage Ratio after
giving effect to the borrowing of the New Tranche B Term Loans.

     VI.  It is appropriate to amend Section 2.4 of the Credit Agreement to
address the use of proceeds of both Term Loans and Revolving Loans made after
the Closing Date.


     THEREFORE, in consideration of the foregoing and the covenants and
conditions hereinafter set forth, and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the Borrower, the
Agents and the Lenders signatory hereto, hereby agree as follows:

     1.   Amendments to Credit Agreement.
          ------------------------------

               (a)  The definition of "Permitted Sponsor Subordinated Debt" in
Section 1.1 of the Credit Agreement, is hereby amended in its entirety to read
as follows:

          "`Permitted Sponsor Subordinated Debt' means subordinated unsecured
     loans from one or more Sponsors and/or MEM to Holdings or Borrower,
     provided (i) prior to the payment in full in Cash of all of the Obligations
     no payment in respect of the principal of or interest on any such loan
     shall be required or made (unless otherwise approved by Requisite Lenders),
     (ii) no such loan shall mature earlier than June 30, 2007, (iii) if any
     such loan is to Holdings, the net proceeds thereof shall either be
     contributed as Equity Capital to Borrower or loaned to Borrower on the
     terms described in clauses (i), (ii) and (iv) hereof (and any such loan to
     Borrower from Holdings shall also constitute "Permitted Sponsor
     Subordinated Debt") and (iv) in all other respects each such loan shall be
     subordinated to all of the Obligations on terms and conditions acceptable
     to Requisite Lenders; provided, if any Permitted Sponsor Subordinated Debt
     is issued on or prior to the Closing Date, it shall be referred to as
     `Closing Date Sponsor Debt'".

               (b)  The second sentence of Section 2.4 of the Credit Agreement
is hereby amended by deleting the word "Revolving" in the first line thereof.

     2.   Consent.  The terms and conditions of the Subordinated Note are accept
          -------
able to the undersigned, and the loan incurred pursuant to the Subordinated Note
will constitute "Permitted Sponsor Subordinated Debt" under the Credit
Agreement.

     3.   Waiver.  For purposes of calculating each of the Total Leverage Ratio
          ------
and the Senior Leverage Ratio for the period of time from the date of the
proposed borrowing of $30,000,000 of New Tranche B Term Loans until September
29, 1999, the Borrower shall be permitted to reduce the amount of Consolidated
Total Debt by an amount equal to the aggregate amount of Cash and Cash
Equivalents that is maintained from time to time in an account (the "Account")
over which the Administrative Agent has a perfected security interest by means
of control pursuant to a control agreement that is in form and substance
satisfactory to the Administrative Agent; provided that the amount that shall be
                                          --------
deposited in the Account on  the Transition Date shall be equal to the
difference between the aggregate principal amount of New Tranche B Term Loans
and the amount of proceeds of such New Tranche B Term Loans that is used to
prepay Revolving Loans on

                                       2
