agree that the $18,063,000 of Net Proceeds from the Instromedix Sale (as defined

applied to repay the Term Loans shall be the final amount of Net Proceeds from

Amendment No. 7.

            27. (a) Notwithstanding anything to the contrary contained in the
Credit Agreement, but subject to the terms and conditions of this Amendment, the
Banks hereby agree that the Borrower shall have two options for obtaining
financing the proceeds of which may and will be used to redeem or repurchase the
7-1/4% Debentures (one of which option is hereinafter referred to as "Financing
Option 1" and the other of which is hereinafter referred to as "Financing Option
2"). Either or both of Financing Option 1 and Financing Option 2 may be
exercised by the Borrower at any time after the Amendment Effective Date through
January 14, 2002, provided that (i) at the time of any such exercise, no Event
of Default shall have occurred and be continuing and (ii) the aggregate
principal amount of Indebtedness incurred by the Borrower under Financing Option
1 and Financing Option 2 combined (exclusive of PIK interest thereon, as
provided below) shall not exceed $15,000,000.

            (b) The terms and conditions of Financing Option 1 and Financing
Option 2 shall be as follows:
<PAGE>

            (i) Under Financing Option 1, the Banks will permit up to
      $15,000,000 (the "Funds") to be incurred by the Borrower under the
      existing Credit Agreement, by creating a new E Term Loan Facility
      ("Tranche E") thereunder as set forth below, but only if: (x) at the time
      of such exercise, there exists any one or more Banks or parties acceptable
      to the Required Banks who or which, as the case may be, desire to become
      Banks for this purpose (each an "E Bank"), ready, willing and able to lend
      the Funds to the Borrower; and (y) all agreements, instruments and
      documents relating to Tranche E and the Indebtedness created thereby are
      acceptable, in form and substance, to each of the Required Banks, the E
      Banks, the Borrower, the Party (as hereinafter defined) and the Issuing
      Party (as hereinafter defined). Indebtedness under Tranche E will be
      pari-passu (both as to repayment of principal and payment of interest, as
      well as collateral) with the other Obligations under the Credit Agreement.
      Tranche E indebtedness will bear pay-in-kind ("PIK") interest at the
      annual rate of 450 basis points above the Eurodollar Rate, with all
      principal and accrued PIK interest payable (absent an acceleration) one
      month following the D Term Loan Maturity Date; provided that, at the time
      of creation of Tranche E, Jeffry Picower or another party acceptable to
      the E Banks (in either case, the "Party"); (A) unconditionally promises
      that upon the exercise of a put to him by the E Banks, at any time on or
      after the occurrence of a Put Triggering Event (as defined below), he will
      immediately purchase a 100% participation in Tranche E at par (all
      principal, plus accrued interest); (B) provides to the E Banks a letter of
      credit in form and substance satisfactory to the E Banks and issued by a
      party (the "Issuing Party") acceptable to the E Banks, which may be drawn
      against by the E Banks, unconditionally, at any time the E Banks determine
      entitlement to exercise the put option exists (with the amount of such
      letter of credit sufficient to pay the entire purchase price of the 100%
      participation above referred to); and (C) agrees, for himself and his
      successors and assigns, that, upon such purchase, the right of Tranche E
      indebtedness to repayment of principal and payment of interest is
      subordinate to repayment of all other Obligations under the Credit
      Documents. For purposes of the foregoing, a "Put Triggering Event" shall
      mean the earliest of (I) an acceleration of the maturity of the
      Obligations pursuant to the terms of the Credit Agreement, (II) the
      occurrence of an Event of Default under Section 9.01 of the Credit
      Agreement and (III) the occurrence of a Default or Event of Default under
      Section 9.05 of the Credit Agreement.

            (ii) Under Financing Option 2, the Banks will permit the Borrower,
      pursuant to agreements, instruments and documents acceptable to the
      Administrative Agent and the Borrower, to borrow the Funds from Picower or
      from any one or more other parties acceptable to the Administrative Agent,
      all of which Funds must (x) call for repayment of principal and payment of
      interest no sooner than one month following the D Term Loan Maturity Date,
      (y) be subordinate, in right of repayment of principal and payment of
      interest, to repayment of all Obligations and (z) not violate the terms of
      any of the agreements, instruments and documents governing any other
      Indebtedness of Holdings, the Borrower or any of their respective
      Subsidiaries.

            (c) The net proceeds of borrowings (the "New Borrowings") made by
the Borrower under this Section 27 shall only be used by the Borrower to
purchase and pay for the 7-1/4% Debentures as otherwise provided for herein.
<PAGE>

            (d) For the purposes of compliance with (i) Sections 8.10 and 8.12
of the Credit Agreement, PIK interest which accrues on the Funds shall not be
included as Consolidated Interest Expense and (ii) Section 8.11 of the Credit
Agreement, outstanding principal of the Funds shall not be included as
Consolidated Debt.

            28. In order to induce the Banks to enter into this Amendment, each
of Holdings and the Borrower hereby represents and warrants that (i) the
representations and warranties contained in the Credit Agreement and the other
Credit Documents are true and correct in all material respects on and as of the
Amendment Effective Date (as defined below), after giving effect to this
Amendment, and (ii) there exists no Default or Event of Default on the Amendment
Effective Date, after giving effect to this Amendment.

            29. This Amendment is limited as specified and shall not constitute
a modification, acceptance or waiver of any other provision of the Credit
Agreement or any other Credit Document.

            30. This Amendment may be executed in any number of counterparts and
by the different parties hereto on separate counterparts, each of which
counterparts when executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A complete set of
counterparts shall be lodged with Holdings, the Borrower and the Agents.

            31. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE
STATE OF NEW YORK.

            32. This Amendment shall become effective on the date (the
"Amendment Effective Date") when each of Holdings, the Borrower, the Agents and
the Required Banks shall have signed a counterpart hereof (whether the same or
different counterparts) and shall have delivered (including by way of
telecopier) the same to the Administrative Agent at the Notice Office.

            33. The Borrower hereby agrees to pay to the Administrative Agent
for the account of each Bank that has executed a counterpart hereof and
delivered same to the Administrative Agent at the Notice Office on or prior to
5:00 P.M. (New York time) on April 13, 2001, an amendment fee equal to 0.25% of
the sum of (x) such Bank's Revolving Loan Commitment (after giving effect to the
reduction to same pursuant to this Amendment) and (y) the aggregate principal
amount of its outstanding A Term Loans, B Term Loans, C Term Loans and D Term
Loans, in each case on the Amendment Effective Date, which amendment fee shall
only be payable if the Amendment Effective Date occurs on or prior to April 13,
2001, and shall be due and payable at 10:00 A.M. (New York time) on April 16,
2001.

            34. From and after the Amendment Effective Date, all references in
the Credit Agreement and in the other Credit Documents to the Credit Agreement
shall be deemed to be references to the Credit Agreement as modified hereby.
