                  (a) Commitment. Subject to the terms and conditions hereof and
         in reliance upon the representations and warranties set forth herein,
         each Lender severally agrees to make available to the Borrower such
         Lender's Commitment Percentage of revolving credit loans requested by
         the Borrower in Dollars ("Revolving Loans") from time to time from the
         Closing Date until the Maturity Date, or such earlier date as the
         Commitments shall have been terminated as provided herein; provided,
         however, that the sum of the aggregate outstanding principal amount of
         Revolving Loans shall not exceed the Committed Amount; provided,
         further, (A) with regard to each Lender individually, such Lender's
         outstanding principal amount of Revolving Loans shall not exceed such
         Lender's Commitment Percentage of the Committed Amount, (B) the sum of
         the aggregate outstanding principal amount of Revolving Loans plus LOC

         and (C) the sum of the aggregate outstanding principal amount of
         Revolving Loans plus Swingline Loans shall not exceed the Borrowing
         Base. Revolving Loans may consist of Base Rate Loans or Eurodollar
         Loans, or a combination thereof, as the Borrower may request; provided,
         however, that no more than 10 Eurodollar Loans shall be outstanding
         hereunder at any time (it being understood that, for purposes hereof,
         Eurodollar Loans with different Interest Periods shall be considered as
         separate Eurodollar Loans, even if they begin on the same date,
         although borrowings, extensions and conversions may, in accordance with
         the provisions hereof, be combined at the end of existing Interest
         Periods to constitute a new Eurodollar Loan with a single Interest
         Period). Revolving Loans hereunder may be repaid and reborrowed in
         accordance with the provisions hereof.

                           (ii) Minimum Amounts. Each Eurodollar Loan or Base
                  Rate Loan that is a Loan shall be in a minimum aggregate
                  principal amount of $500,000 and integral multiples of $50,000
                  in excess thereof (or the remaining amount of the Committed
                  Amount, if less), subject to Sections 2.2(e) and 2.3(b)(iii).

         SUBPART 2.3 Amendments to Section 2.3. Section 2.3(a) of the Existing
Credit Agreement is hereby amended and restated in its entirety to read as
follows:

                  2.3      Swingline Loan Subfacility.

                  (a) Swingline Commitment. Subject to the terms and conditions
         hereof and in reliance upon the representations and warranties set
         forth herein, the Swingline Lender, in its individual capacity, agrees
         to make certain revolving credit loans requested by the Borrower in
         Dollars to the Borrower (each a "Swingline Loan" and, collectively, the
         "Swingline Loans") from time to time from the Closing Date until the
         Maturity Date for the purposes hereinafter set forth; provided,
         however, (i) the aggregate principal amount of Swingline Loans
         outstanding at any time shall not exceed ZERO DOLLARS ($0) (the
         "Swingline Committed Amount"), (ii) the sum of the aggregate
         outstanding principal amount of Revolving Loans plus LOC Obligations
         plus Swingline Loans shall not exceed the Committed Amount and (iii)
         the sum of the aggregate outstanding principal amount of Revolving
         Loans plus Swingline Loans shall not exceed the Borrowing Base.
         Swingline Loans hereunder shall be made as Base Rate Loans and may be
         repaid and reborrowed in accordance with the provisions hereof.

         SUBPART 2.4 Amendments to Section 3.3. Section 3.3 of the Existing
Credit Agreement is hereby amended and restated in its entirety to read as
follows:

         3.3      Prepayments.

                  (a) Voluntary Prepayments. The Borrower shall have the right
         to prepay Loans in whole or in part from time to time; provided,
         however, that each partial prepayment of Loans (other than Swingline
         Loans) shall be in a minimum principal amount of $500,000 and integral
         multiples of $50,000 in excess thereof (or the then remaining principal
         balance of the Revolving Loans, if less). Subject to the foregoing
         terms, amounts prepaid under this Section 3.3(a) shall be applied as
         the Borrower may elect; provided that if the Borrower fails to specify
         a voluntary prepayment then such prepayment shall be applied to Loans,
         first to Base Rate Loans and then to Eurodollar Loans in direct order
         of Interest Period maturities. All prepayments under this Section
         3.3(a) shall be subject to Section 3.12, but otherwise without premium
         or penalty, and, in the case of Eurodollar Loans, shall be accompanied
         by interest on the principal amount prepaid through the date of
         prepayment.

                  (b)      Mandatory Prepayments.
                           ---------------------

                           (i) Committed Amount/ Borrowing Base. If at any time,
                  the sum of the aggregate outstanding principal amount of
                  Revolving Loans plus LOC Obligations plus Swingline Loans
                  shall exceed the Committed Amount, the Borrower immediately
                  shall prepay the Revolving Loans and (after all Revolving
                  Loans have been repaid) cash collateralize the LOC
                  Obligations, in an amount sufficient to

                  eliminate such excess. If at any time, the sum of the
                  aggregate outstanding principal amount of Revolving Loans
                  plus Swingline Loans shall exceed the Borrowing Base, the
                  Borrower immediately shall prepay the Revolving Loans and
                  Swingline Loans, in an amount sufficient to eliminate such
                  excess.

                           (ii) Cash on Hand. If at any time the cash on hand
                  and Cash Equivalents of the Consolidated Parties exceed
                  $6,000,000, the Borrower shall immediately prepay the Loans in
                  an aggregate amount equal to such excess (except to the extent
                  that such excess is attributable to Net Cash Proceeds or
                  Excess Proceeds from Asset Dispositions or Involuntary
                  Dispositions, as the case may be, which have not yet been
                  required to be applied to the prepayment of the Loans pursuant
                  to clause (iii) below) (such prepayment to be applied as set
                  forth in clause (v) below).

                           (iii) (A) Asset Dispositions. Immediately upon the
                           occurrence of any Asset Disposition Prepayment Event,
                           the Borrower shall prepay the Loans in an aggregate
                           amount equal to 100% of the Net Cash Proceeds of the
                           related Asset Disposition not applied (or caused to
                           be applied) by the Credit Parties to make Eligible
                           Reinvestments within the Application Period (such
                           prepayment to be applied as set forth in clause (v)
                           below).

                                 (B) Casualty and Condemnation Events.
                           Immediately upon the occurrence of any event
                           requiring application of any Excess Proceeds to the
                           prepayment of Loans (and cash collateralization of
                           LOC Obligations) pursuant to Section 7.6(b), the
                           Borrower shall prepay the Loans in the amount
                           required by such Section 7.6(b) (such prepayment to
                           be applied as set forth in clause (v) below).

                           (iv) Equity Issuances. Immediately upon receipt by a
                  Consolidated Party of proceeds from the Equity Issuance
                  required under Subpart 4.1.3 of Amendment No. 2 or made
                  pursuant to clause (viii) of the definition of "Permitted
                  Acquisition", the Borrower shall prepay the Loans in an
                  aggregate amount equal to 100% of the Net Cash Proceeds of
                  such Equity Issuance (such prepayment to be applied as set
                  forth in clause (v) below).

                           (v) Application of Mandatory Prepayments. All amounts
                  required to be paid pursuant to this Section 3.3(b) shall be
                  applied to Revolving Loans and Swingline Loans. Within the
                  parameters of the applications set forth above, prepayments
                  shall be applied first to Swingline Loans, second to Revolving
                  Loans which are Base Rate Loans and third to Revolving Loans
                  which are Eurodollar Loans (in direct order of Interest Period
                  maturities). All prepayments under this Section 3.3(b) shall
                  be subject to Section 3.12, but otherwise without premium or
                  penalty, and shall be accompanied by interest on the principal
                  amount prepaid through the date of prepayment.

                           (vi) Prepayment Account. If the Borrower is required
                  to make a mandatory prepayment of Eurodollar Loans under this
                  Section 3.3(b), the Borrower shall have the right, in lieu of
                  making such prepayment in full, to deposit an amount equal to
                  such mandatory prepayment with the Agent in a cash

                  collateral account maintained (pursuant to documentation
                  reasonably satisfactory to the Agent) by and in the sole
                  dominion and control of the Agent. Any amounts so deposited
                  shall be held by the Agent as collateral for the prepayment
                  of such Eurodollar Loans and shall be applied to the
                  prepayment of the applicable Eurodollar Loans at the end of
                  the current Interest Periods applicable thereto. At the
                  request of the Borrower, amounts so deposited shall be
                  invested by the Agent in Cash Equivalents maturing prior to
                  the date or dates on which it is anticipated that such
                  amounts will be applied to prepay such Eurodollar Loans; any
                  interest earned on such Cash Equivalents will be for the
                  account of the Borrower and the Borrower will deposit with
                  the Agent the amount of any loss on any such Cash
                  Equivalents to the extent necessary in order that the amount
                  of the prepayment to be made with the deposited amounts may
                  not be reduced.

         SUBPART 2.5 Amendments to Section 3.4. Sections 3.4(a)(i) and 3.4(b)(1)
of the Existing Credit Agreement are hereby amended and restated in their

                  permanently reduce or terminate the Committed Amount in whole
                  or in part (in minimum aggregate amounts of $500,000 or in
                  integral multiples of $50,000 in excess thereof (or, if less,
                  the full remaining amount of the then applicable Committed
                  Amount)) upon three Business Days' prior written notice to the
                  Agent; provided, however, no such termination or reduction
                  shall be made which would cause the sum of the aggregate
                  outstanding principal amount of Revolving Loans plus LOC
                  Obligations plus Swingline Loans to exceed the Committed
                  Amount unless, concurrently with such termination or
                  reduction, the Loans are repaid to the extent necessary to
                  eliminate such excess. The Agent shall promptly notify each
                  affected Lender of receipt by the Agent of any notice from the
                  Borrower pursuant to this Section 3.4(a).

         the Committed Amount, subject, however, to satisfaction of the
         following conditions precedent:

                           (1) no Event of Default shall have occurred and be
                  continuing on the date on which such Committed Amount increase
                  is to become effective, and the Total Leverage Ratio as of the
                  most recent fiscal quarter end preceding the date of such
                  increase with respect to which the Agent has received the
