    WHEREAS,
the Borrower and the Lenders wish to make certain amendments to the Credit Agreement;

    NOW,
THEREFORE, in consideration of the mutual covenants and agreements set forth herein and for other good and valuable consideration, the receipt and sufficiency of which hereby are

    (3) it
is a valid, legally enforceable and unconditional obligation of the Account Debtor with respect thereto, and, other than as granted by Borrower in the ordinary
course of its business, is not subject to any counterclaim, credit, allowance, discount, rebate or adjustment by the Account Debtor with respect thereto, or to any claim by such Account Debtor denying
liability thereunder in whole or in part;

    (4) there
is no bankruptcy, insolvency or liquidation proceeding by or against the Account Debtor with respect thereto;

    (5) the
Account Debtor with respect thereto is a resident or citizen of, and is located within, the United States or Canada, unless the sale of goods or services giving
rise to such Account Receivable is on letter of credit, banker's acceptance or other credit support terms reasonably satisfactory to the Agent;

    (6) it
is not an Account Receivable arising from a "sale on approval," "sale or return," "consignment" or "bill and hold" or subject to any other repurchase or return
agreement;

    (8) it
arises in the ordinary course of business of the Borrower;

the Borrower maintains a credit limit for an Account Debtor, the aggregate dollar amount of Accounts Receivable due from such Account Debtor, including such
Account Receivable, does not exceed such credit limit;

enforce its claims in such jurisdiction's courts

exemption;

   (14) the
Account Debtor with respect thereto is not an Affiliate of the Borrower;

Eligible Account Receivable. Further, with respect to any Account Receivable, if the Agent or the Required Lenders at any time hereafter determine in their reasonable discretion that the prospect of
payment or performance by the Account Debtor with respect thereto is materially impaired for any reason whatsoever, such Account Receivable shall cease to be an Eligible Account Receivable after
notice of such determination is given to the Borrower.

"Eligible
Subcontracted Account Receivable" means an Account Receivable owing to the Borrower which, except for the fact that it arises from the rendering of services or sale of goods through a
subcontractor of Borrower and billed by the Borrower on a fee basis, instead of arising under a direct contract with Borrower (pursuant to agreements or arrangements satisfactory to the Agent), would

    2.1.  Commitment.  From and including the date of this Agreement and prior to the Facility Termination
Date, each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Loans to the Borrower from time to time in amounts not to exceed in the aggregate at any one time
outstanding its Pro Rata Share of the Available Aggregate Commitment, provided that at no time shall
the Aggregate Outstanding Credit Exposure hereunder exceed the Borrowing Base as then determined and computed. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow at
any time prior to the Facility Termination Date. The Commitments to lend hereunder shall expire on the Facility Termination Date.

	•
	Any
outstanding Advances and all other unpaid Obligations shall be paid in full by the Borrower on the Facility Termination Date.

	•
	Each
Advance hereunder (other than any Swing Line Loan) shall consist of Revolving Loans made from the several Lenders ratably in proportion to the ratio
that their respective Commitments bear to the Aggregate Commitment.

	•
	The
Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.9 and
2.10, or Swing Line Loans selected by the Borrower in accordance with Section 2.5.

    2.5.1.  Amount of Swing Line Loans.  Upon the satisfaction of the conditions precedent set forth in
Section 4.2, from and including the Fifth Amendment Closing Date prior to the Facility Termination Date, the Swing Line Lender agrees, on the terms and conditions set forth in this Agreement,
to make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line Commitment, providedthat the Aggregate Outstanding Credit Exposure shall not
at any time exceed the lesser of (a) Aggregate Commitment or (b) the Borrowing Base,
and provided further that at no time shall the sum of (i) the Swing Line Lender's Pro Rata Share of the Swing Line
Loans, plus (ii) the outstanding Revolving Loans made by the Swing Line Lender pursuant to Section 2.1, exceed the Swing
Line Lender's Commitment at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Facility Termination Date.

    2.5.2.  Borrowing Notice.  The Borrower shall deliver to the Agent and the Swing Line Lender irrevocable
notice (a "Swing Line Borrowing Notice") not later than noon (Chicago time) on the Borrowing Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date shall be a
Business Day), and (ii) the aggregate amount of the requested Swing Line Loan which shall be an amount not less than $1,000,000 or any integral multiple of $100,000 in excess thereof. The Swing
Line Loans shall bear interest at the Floating Rate.

    2.5.3.  Making of Swing Line Loans.  Promptly after receipt of a Swing Line Borrowing Notice, the Agent
shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 2:00 p.m. (Chicago time) on the applicable Borrowing Date, the Swing
Line Lender shall make available the Swing Line Loan, in funds immediately available in Chicago, to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the
funds so received from the Swing Line Lender available to the Borrower on the Borrowing Date at the Agent's aforesaid address.

    2.5.4.  Repayment of Swing Line Loans.  Each Swing Line Loan shall be paid in full by the Borrower on or
before the third (3rd) Business Day after the Borrowing Date for such Swing Line Loan. In addition, the Swing Line Lender (i) may at any time in its sole discretion with respect to any
outstanding Swing Line Loan, or (ii) shall on the third (3rd) Business Day after the Borrowing Date of any Swing Line Loan, require each Lender (including the Swing Line Lender) to make a
Revolving Loan in the amount of such Lender's Pro Rata Share of such Swing Line Loan, for the purpose of repaying such Swing Line Loan. Not later than noon (Chicago time) on the date of any notice
received pursuant to this Section 2.5.4, each Lender shall make available its required Revolving Loan, in funds immediately available in Chicago to the Agent at its address specified pursuant
to Article XIII. Revolving Loans made pursuant to this Section 2.5.4 shall initially be Floating Rate Loans and thereafter may be continued as Floating Rate Loans or converted into
Eurodollar Loans in the manner provided in
Section 2.10 and subject to the other conditions and limitations set forth in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing
Line Loan, that any applicable condition precedent set forth in Sections 4.1 had not then been satisfied, such Lender's obligation to make Revolving Loans pursuant to this Section 2.5.4 to
repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including, without limitation, (a) any set-off,
counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (b) the occurrence or continuance of a Default or
Unmatured Default, (c) any adverse change in the condition (financial or otherwise) of the Borrower, or (d) any other circumstances, happening or event whatsoever. In

the
event that any Lender fails to make payment to the Agent of any amount due under this Section 2.5.4, the Agent shall be entitled to receive, retain and apply against such obligation the
principal and interest otherwise payable to such Lender hereunder until the Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. In addition to the foregoing,
if for any reason any Lender fails to make payment to the Agent of any amount due under this Section 2.5.4, such Lender shall be deemed, at the option of the Agent, to have unconditionally and
irrevocably purchased from the Swing Line Lender, without recourse or warranty, an undivided interest and participation in the applicable Swing Line Loan in the amount of such Revolving Loan, and such
interest and participation may be recovered from such Lender together with interest thereon at the Federal Funds Effective Rate for each day during the period commencing on the date of demand and
ending on the date such amount is received. On the Facility Termination Date, the Borrower shall repay in full the outstanding principal balance of the Swing Line Loans.

	•
	The
Borrower agrees to pay to the Agent for the account of each Lender a commitment fee at a per annum rate equal to the Applicable Fee Rate on the daily
unused portion of such Lender's Commitment from the date hereof to and including the Termination Date, payable on each Payment Date hereafter and on the Facility Termination Date. Swing Line Loans
shall not count as usage of any Lender's Commitment for the purpose of calculating the commitment fee due hereunder. The Borrower may permanently reduce the Aggregate Commitment in whole, or in part
ratably among the Lenders in integral multiples of $5,000,000, upon at least one (1) Business Day's written notice to the Agent, which notice shall specify the amount of any such
reduction, provided, however, that the amount of the Aggregate Commitment may not be reduced below the aggregate principal
amount of the outstanding Advances. All accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Loans hereunder.

	•
	Each
Eurodollar Advance shall be in the minimum amount of $5,000,000 (and in multiples of $1,000,000 if in excess thereof), and each Floating Rate Advance
(other than an Advance to repay Swing Line Loans) shall be in the minimum amount of $1,000,000 (and in multiples of $100,000 if in excess thereof), provided,
however, that any Floating Rate Advance may be in the amount of the unused Aggregate Commitment.

	•
	The
Borrower may from time to time pay, without penalty or premium, all outstanding Floating Rate Advances (other than Swing Line Loans), or, in a minimum
aggregate amount of $1,000,000 or any integral multiple of $100,000 in excess thereof, any portion of the outstanding Floating Rate Advances (other than Swing Line Loans) upon one Business Day's prior
notice to the Agent. The Borrower may at any time pay, without penalty or premium, all outstanding Swing Line Loans, or, in a minimum amount of $1,000,000 and increments of $100,000 in excess thereof,
any portion of the outstanding Swing Line Loans, with notice to the Agent and the Swing Line Lender by 11:00 a.m. (Chicago time) on the date of repayment. The Borrower may from time to time
pay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or, in a minimum aggregate amount
of $5,000,000 or any integral multiple of $1,000,000 in excess thereof, any portion of the outstanding Eurodollar Advances upon three Business Days' prior notice to the Agent.

	•
	The
Borrower shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The
Borrower shall give the Agent irrevocable notice (a "Borrowing Notice") not later than 10:00 a.m. (Chicago time) at least one Business Day before the Borrowing Date of each Floating Rate
Advance (other than a Swing Line Loan) and three Business Days before the Borrowing Date for each Eurodollar Advance, specifying:

    (i)  the
Borrowing Date, which shall be a Business Day, of such Advance,

    (ii) the
aggregate amount of such Advance,

    (iii) the
Type of Advance selected, and

    (iv) in
the case of each Eurodollar Advance, the Interest Period applicable thereto.

Not
later than noon (Chicago time) on each Borrowing Date, each Lender shall make available its Revolving Loan or Revolving Loans in funds immediately available in Chicago to the Agent at its address
specified pursuant to Article XIII. The Agent will make the funds so received from the Lenders available to the Borrower at the Agent's aforesaid address.

	•
	Floating
Rate Advances (other than Swing Line Loans) shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted
into Eurodollar Advances pursuant to this Section 2.10 or are repaid in accordance with Section 2.8. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the
then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar Advance is or was repaid
in accordance with Section 2.8 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period,
such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.7, the Borrower may elect from time to time to convert all or
any part of a Floating Rate Advance (other than a Swing Line Loan) into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a "Conversion/Continuation Notice") of each
conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least three Business Days prior to the date
of the requested conversion or continuation, specifying:

	(i)
	the
requested date, which shall be a Business Day, of such conversion or continuation,

	(ii)
	the
aggregate amount and Type of the Advance which is to be converted or continued, and

	(iii)
	the
amount of such Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable
thereto.

    Each
Floating Rate Advance (other than a Swing Line Loan) shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is
made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.10, to but excluding the date it is paid or is converted into a Eurodollar
Advance pursuant to Section 2.10 hereof, at a rate per annum equal to the Floating Rate for such day. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof, for
each day from and including the day such Swing Line Loan is made to but excluding the date it is paid, at a rate per annum equal to the Floating Rate for each such day. Changes in the rate of interest
on that portion of any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the
outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate
determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower's selections under Sections 2.9 and 2.10 and otherwise in accordance with the terms hereof. No Interest Period
may end after the Facility Termination Date.

    (a) Notwithstanding
anything to the contrary contained in Section 2.9 or 2.10, during the continuance of a Default or Unmatured Default the Required Lenders may,
at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Required Lenders may, at
their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that (i) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such
Interest Period plus 2% per annum and (ii) each Floating Rate Advance shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time
plus 2% per annum, provided that, during the continuance of a Default under Section 7.6 or 7.7, the interest rates set forth in clauses
(i) and (ii) above shall be applicable to all Advances without any election or action on the part of the Agent or any Lender.

    (b) Notwithstanding
anything to the contrary contained in this Agreement at any time prior to December 31, 2000, (i) no Advance may be made as, converted
into or continued as a Eurodollar Advance and (ii) each outstanding Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable
to such Eurodollar Advance plus 2.25% per annum.

    All
payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent's address specified
pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by noon (local time) on the date when due and shall (except with
respect to repayments of Swing Line Loans) be applied ratably by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent
to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent
from such Lender. The Agent is hereby authorized to charge the account of the Borrower maintained with ANB for each payment of principal, interest and fees as it becomes due hereunder.

    (i)  Each
Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from
each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

    (ii) The
Agent shall also maintain accounts in which it will record (a) the amount of each Loan made hereunder, the Type thereof and the Interest Period with
respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (c) the amount of any sum
received by the Agent hereunder from the Borrower and each Lender's share thereof.

    (iii) The
entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima
facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the
Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

    (iv) Any
Lender may request that its Loans be evidenced by a promissory note or, in the case of the Swing Line Lender, promissory notes representing its Revolving Loans
and Swing Line Loans, respectively, substantially in the form of Exhibit E, with appropriate changes for notes evidencing Swing Line Loans (each a "Note"). In such event, the Borrower shall
prepare, execute and deliver to such Lender such Note or Notes payable to the order of such Lender. Thereafter, the Loans evidenced by each such Note and interest thereon shall at all times (including
after any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 12.3, except to the
extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and
(ii) above.

    The
Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic
notices made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically
intended to allow
Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the
Agent or any Lender, of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the
records of the Agent and the Lenders shall govern absent manifest error.

    Interest
accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof and at maturity. Interest
accrued on

each
Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at
maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period.
Interest and commitment fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any
payment on the amount paid if payment is received prior to 1:00 p.m. (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day
which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in
connection with such payment.

    Promptly
after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Swing Line Borrowing Notice,
Conversion/ Continuation Notice, and repayment notice received by it hereunder. The Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination
of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

    Each
Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply
to any such Lending Installation and the Loans and any Notes issued hereunder shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice
to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it and for whose account Loan
payments are to be made.

    Unless
the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender,
the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment,
the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the
amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers
such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate
applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

    2.20.  Required Payments; Termination.  If on any day the Aggregate Outstanding Credit Exposure exceeds
the lesser of (a) the Borrowing Base or (b) Aggregate Commitment, the Borrower shall immediately make a prepayment of the Loans in an amount sufficient to eliminate such excess. Such
prepayments shall be applied first to outstanding Swingline Loans, second to Floating Rate Advances until payment in full thereof, with any balance applied to Eurodollar Advances in the order in which
their Interest Periods expire. Any prepayment applied to the Eurodollar Advances hereunder shall be accompanied by amounts due the Lenders under Section 3.4 hereof.

    (d) Section 4.2
shall be amended in its entirety and as so amended shall read as follows:

    "4.2.  Each Advance.  The Lenders shall (except as otherwise set forth in Section 2.5.4 with
respect to Revolving Loans for the purpose of repaying Swing Line Loans) not be required to make any Advance (other than an Advance that, after giving effect thereto and to the application of the
proceeds thereof, does not increase the aggregate amount of outstanding Advances), unless on the applicable Borrowing Date:

    (i)  There
exists no Default or Unmatured Default.

    (ii) The
representations and warranties contained in Article V are true and correct as of such Borrowing Date except to the extent any such representation or
warranty is stated to relate solely to an earlier date, in which case such representation or warranty shall have been true and correct on and as of such earlier date.

    (iii) All
legal matters incident to the making of such Advance shall be reasonably satisfactory to the Lenders and their counsel.

Each
Borrowing Notice or Swing Line Borrowing Notice, as the case may be, with respect to each such Advance shall constitute a representation and warranty by the Borrower that the conditions contained
in Sections 4.2(i) and (ii) have been satisfied. Any Lender may require a duly completed compliance certificate in substantially the form of Exhibit B as a condition to making an
Advance.

    (e) Section 6.1(ii) shall
be amended in its entirety and as so amended shall read as follows:

"(ii) within
30 days after the end of each month in each year, for itself and its Subsidiaries, consolidated unaudited balance sheets as of the end of such month, and consolidated and

chief financial officer."

    (f)  Section 6.1

"(xii) on
a weekly basis a weekly report of Borrower's and Subsidiaries' six week forward cash flow forecast satisfactory to the Agent and the Lenders."

    (g) Sections
6.24.1 and 6.24.2 of the Credit Agreement shall be amended in their entirety and as so amended shall read as follows:

    6.24.1.  Fixed Charge Coverage Ratio.  The Borrower will not permit the ratio, determined as of the end
of each of its fiscal quarters for the then most-recently ended four fiscal quarters of (i) Consolidated EBIT plus Consolidated
Rentals to (ii) Consolidated Interest Expense, plus Consolidated Rentals, all calculated for the Borrower and its Subsidiaries on a consolidated
basis, to be less than (i) 1.10 to 1.0 as of March 31, 2000, (ii) 0.80 to 1.0 as of June 30, 2000, (iii) 1.25 to 1.0 as of September 30, 2000 and
(iv) 3.0 to 1.0 as of any fiscal quarter end thereafter.

    6.24.2.  Leverage Ratio.  The Borrower will not permit the Leverage Ratio, determined as of the end of
each of its fiscal quarters, to be greater than (i) 4.25 to 1.00 as of March 31, 2000, (ii) 4.50 to 1.0 as of June 30, 2000 and (iii) 3.0 to 1.0 as of any fiscal
quarter end thereafter.

    (h) Section 6.24
of the Credit Agreement is amended by adding a new Section 6.24.4 at the end thereof which shall read as follows:

    6.24.4.  Cumulative Consolidated EBITDA.  The Borrower will have Consolidated EBITDA for the period
commencing January 1, 2000 and ending June 30, 2000 of not less than $2,500,000 and for the period commencing January 1, 200 and ending September 30, 2000 the Borrower will
have Consolidated EBITDA of not less than $7,500,000.

    (i)  Clause (vii)
of Section 6.14 of the Credit Agreement shall be deleted.

    (j)  Section 6.16
of the Credit Agreement shall be amended in its entirety and as so amended shall read as follows:

    "6.16  Capital Expenditures.  The Borrower will not, nor will it permit any Subsidiary to, expend, to be
committed to expend, in excess of $7,000,000 during any one fiscal year for Capital Expenditures nor will it expend or commit to expend more than $2,000,000 for capital

expenditures
during any fiscal quarter on a non-cumulative basis in the aggregate for the Borrower and its Subsidiaries."

    (k) Article VI
of the Credit Agreement shall be amended by adding the following section in the appropriate numerical order:

    6.29  Borrowing Base Certificates.  Within 20 days of the end of each month, a Borrowing Base
Certificate dated as of the end of such month and executed by the Chief Financial Officer or the Vice President Finance of the Borrower on behalf of the Borrower
(provided that (i) the Borrower may deliver a Borrowing Base Certificate more frequently if it chooses and (ii) at any time an Unmatured
Default or Default exists, the Agent may require the Borrower to deliver Borrowing Base Certificates more frequently).

    (l)  Section 8.2

Agent through the date hereof.
