               (a) Subject to the terms and conditions contained herein, Lender

Agreement as a result of the failure of Borrower to comply with Section 8.10 and
Section 8.10A of the Loan Agreement as of December 31, 1998, provided, that, (i)
such waiver shall only apply to the failure of Borrower to comply with such

referred to in Section 4(a) for the period ending December 31, 1998. Upon the
occurrence of any other Event of Default, whether or not continuing on the date

discretion, to exercise any and all of its rights and remedies under the Loan
Agreement, the other Financing Agreements, applicable law or otherwise.

               (c) The foregoing waiver shall not be construed as a bar to or a
waiver of any other or further Event of Default on any future occasion, whether
similar in kind or otherwise and shall not constitute a waiver, express or
implied of any of the rights and remedies of Lender arising under the terms of
the Financing Agreements of any future occasion or otherwise.

         3. Fee. In consideration of the terms hereof, Borrower shall pay to
Lender a fee in the amount of $10,000, which fee is fully earned as of the date
hereof and shall be payable upon the earliest of the occurrence of an Event of
Default, or termination or non-renewal of the financing arrangements between
Lender and Borrower under the Loan Agreement or the sale by Borrower of all or
any substantial portion of its physical therapy business or the Final Date.

by Borrower and Guarantors and is in full force and effect as of the date
