                 ACKNOWLEDGEMENT AND CONFIRMATION OF GUARANTIES

         THIS ACKNOWLEDGEMENT AND CONFIRMATION (the "ACKNOWLEDGEMENT") is made
  and entered into as of November 8, 1999, by and between the entities listed
  on EXHIBIT "A" attached hereto (each a "GUARANTOR" and collectively, the
  "GUARANTORS") and DVI BUSINESS CREDIT CORPORATION ("LENDER").

                                   BACKGROUND

         A.  Pursuant to various Unconditional Continuing Guaranties dated
  February 25, 1997, June 29, 1999, or November 8, 1999, as the case may be, by
  and between Guarantors and Lender (each a "Guaranty" and collectively, the
  "GUARANTIES"), each Guarantor has agreed to guaranty and become surety for all
  present and future obligations of US Diagnostic, Inc. ("BORROWER") to Lender,
  including, without limitation, all obligations arising under that certain Loan
  and Security Agreement dated February 25, 1997, by and between Borrower and
  Lender, as amended (the "LOAN AGREEMENT"), the Notes executed thereunder and
  all documents, instruments and agreements related thereto (all of the
  foregoing being collectively, the "LOAN DOCUMENTS").

         B.  Borrower has agreed to divide the Loan, the Notes and the
  Collateral under the Loan Documents into two (2) distinct and separate
  obligations, which obligations may subsequently be merged or
  cross-collateralized.

         C.  All capitalized terms not defined herein shall have the meaning set
  forth in the Loan Agreement.

         NOW, THEREFORE, the parties hereto, intending to be legally bound and
  for good and valuable consideration, agree as follows:

         1.  ACKNOWLEDGEMENT AND CONFIRMATION OF OBLIGATIONS. Each Guarantor
  hereby acknowledges and confirms its unconditional continuing guarantee of the
  due and punctual payment, performance and discharge of any and all present and
  future Obligations (as defined in that Guarantor's Guaranty) of Borrower to
  Lender, including, without limitation, Borrower's obligations under Note A and
  under Note B, whether or not such obligations are divided or subsequently
  merged or cross-collateralized.

         2.  COUNTERPARTS. This Acknowledgement may be executed in counterparts,
  all of which when taken together constitute one and the same instrument.

         3.  GOVERNING LAW. This Acknowledgement is governed by and must be
  interpreted and construed in accordance with the laws of the State of
  California (without giving effect to any principles of conflicts of law).
