hereto hereby agree as follows:

          SECTION 1. AMENDMENTS AND MODIFICATIONS OF CERTAIN PROVISIONS OF THE

add the following new definitions in the appropriate alphabetical order:

                  "AMENDMENT NO. 10 EFFECTIVE DATE" means the first date on

          (b) Section 1.01 of the Credit Agreement is hereby further amended to
restate the following definition set forth therein in its entirety to read as
follows:

     Agreement, the Senior Subordinated Notes, the New Senior Subordinated
     Notes, all indentures, securities purchase agreements, warrant agreements
     and registration rights agreements entered into in connection with the
     redemption or refinancing of the initial Senior Subordinated Notes and all

     the Senior Subordinated Notes and the New Senior Subordinated Notes have
     been issued or otherwise setting forth the terms of the Senior Subordinated
     Notes and the New Senior Subordinated Notes, in each case as such
     agreement, instrument or other document may be amended, supplemented or
     otherwise modified from time to time in accordance with the terms thereof,
     but solely to the extent permitted under the terms of the Loan Documents.

          (c) Section 2.06(b)(ii) of the Credit Agreement is hereby amended by
replacing the period at the end thereof with the following:

                  "; PROVIDED, HOWEVER, that the Net Cash Proceeds of the New
     Senior Subordinated Notes shall instead be applied as follows: FIRST,
     $25,000,000 of such Net Cash Proceeds shall be retained by the Borrower to
     be used for working capital and other general corporate purposes, SECOND,
     so much of the remaining portion of such Net Cash Proceeds as shall be
     necessary shall be applied to pay in full the outstanding principal amount
     of the Term A Facility and THIRD, the then remaining portion of such Net
     Cash Proceeds shall be applied to prepay the principal installments of the
     Term B Facility on a PRO RATA basis, except that if the New Senior
     Subordinated Notes are issued in an aggregate principal amount greater than
     $75,000,000, only 50% of the Net Cash Proceeds thereof attributable to the
     principal amount being over $75,000,000 shall be applied to prepay the
     principal installments of the Term B Facility on a PRO RATA basis and the
     other 50% of such Net Cash Proceeds shall be retained by the Borrower to be
     used for working capital and other general corporate purposes."

          (d) Section 5.02(b)(i)(B) of the Credit Agreement is hereby amended by
replacing the dollar amount "$150,000,000" with the dollar amount
"$250,000,000".
