            (b) a Revolving Loan Commitment (to include availability for

      Borrowings of Revolving Loans, in a maximum aggregate principal amount
      (together with all Swing Line Loans and Letter of Credit Outstandings) not
      to exceed $105,000,000 will be made to the Borrower from time to time on
      and subsequent to the Closing Date but prior to the Revolving Loan
      Commitment Termination Date; provided, however, that not more than
      $10,000,000 of the proceeds from Revolving Loans may be used for purposes
      of consummating the Transaction, including the payment of related costs
      and expenses;

            (c) a Letter of Credit Commitment pursuant to which the Issuer will
      issue Letters of Credit for the account of the Borrower and its

      Commitment Termination Date (provided, that the aggregate outstanding
      principal amount of such Swing Line Loans, together with Revolving Loans
      and Letter of Credit Outstandings, at any time shall not exceed the then
      existing Revolving Loan Commitment Amount);

      WHEREAS, on the Closing Date, contemporaneously with the consummation of
the Merger, the Discount Debenture Issuance, the Subordinated Debt Issuance and
the initial Borrowing of Term Loans and Revolving Loans hereunder, the Borrower
shall distribute to Holdings as a dividend (the "Closing Date Dividend") and/or
make an intercompany loan (the "Intercompany Loan") in an amount equal to all of
the net proceeds of the Subordinated Debt Issuance and the initial Borrowing of
Term Loans and Revolving Loans (other than any such proceeds used by the
Borrower to repay existing Indebtedness of the Borrower and its Subsidiaries and
to pay fees and expenses related to the Transaction) for purposes of
consummating the Merger, which Intercompany Loan shall be evidenced by a
promissory note issued by Holdings to the Borrower (the "Intercompany Note");

      WHEREAS, the Lenders are willing, on the terms and subject to the
conditions hereinafter set forth (including Article V), to extend the
Commitments and make the Loans described herein to the Borrower and issue (or
participate in) Letters of Credit for the account of the Borrower and its

have been acquired by the Borrower or any of its Restricted Subsidiaries,
including through mergers or consolidations, after the first day of such period

Fiscal Quarters and (iii) Adjusted EBITDA and expenses attributable to
discontinued operations as determined in accordance with GAAP, and operations,
businesses and assets disposed of prior to the end of such period of four Fiscal
Quarters, shall be excluded. For purposes of the foregoing clause (i), Adjusted
EBITDA attributable to any business or assets acquired by the Borrower or any

attributable to such business or assets for the applicable three-month period
and the expenses that would have been attributable to such business or assets
had the Borrower acquired such business or assets at the beginning of the
applicable three-month period, as determined in good faith by the Borrower,
taking into account the Borrower's historical expenses in connection with the
provision of similar services for similar equipment under similar contracts. If
since the beginning of the applicable period of four Fiscal Quarters any Person
(that subsequently becomes a Restricted Subsidiary or was merged with or into
the Borrower or any Restricted Subsidiary since the beginning of such period)
shall have made or engaged in any Investment, disposition of operations,
businesses or assets, or merger or consolidation, or shall have discontinued any
operations or acquired any business or assets that would have required
adjustment of the Fixed Charge Ratio, Interest Coverage Ratio or Leverage Ratio
pursuant to this subsection (b) had such Person been a Restricted Subsidiary at
the time of such Investment, disposition, merger, consolidation, discontinued
operation or acquisition, then the Fixed Charge Coverage Ratio, Interest
Coverage Ratio and Leverage Rates shall be calculated giving pro forma effect
thereto for such period as if such Investment, acquisition, disposition, merger,
consolidation or discontinued operation had occurred at the beginning of the
applicable period of four Fiscal Quarters.

                          NOTES AND LETTERS OF CREDIT

      SECTION 2.1. Commitments. On the terms and subject to the conditions of
this Agreement (including Sections 2.1.4, 2.1.5 and Article V),

            (a) each Lender severally agrees to make Loans (other than Swing

      Credit pursuant to Section 2.1.3, and each other Lender that has a

Borrower with the terms of Sections 2.1.4, 5.1 and 5.2, on (but solely on) the
Closing Date (which shall be a Business Day), each Lender that has a Percentage
in excess of zero of the Term-A Loan Commitment or the Term-B Loan Commitment,
as applicable,

            (a) will make loans (relative to such Lender, its "Term-A Loans") to
      the Borrower equal to such Lender's Percentage of the aggregate amount of
      the Borrowing or Borrowings of Term-A Loans requested by the Borrower to

      described in this clause (a) herein referred to as its "Term-A Loan
      Commitment"); and

            (b) will make loans (relative to such Lender, its "Term-B Loans") to
      the Borrower equal to such Lender's Percentage of the aggregate amount of
      the Borrowing or Borrowings of Term-B Loans requested by the Borrower to
      be made on the Closing Date (with the commitment of each such Lender
      described in this clause (b) herein referred to as its "Term-B Loan
      Commitment").

No amounts paid or prepaid with respect to Term-A Loans or Term-B Loans may be
reborrowed.

      SECTION 2.1.2. Revolving Loan Commitment and Swing Line Loan Commitment.
Subject to compliance by the Borrower with the terms of Section 2.1.4, Section
5.1 and Section 5.2, from time to time on any Business Day occurring
concurrently with (or after) the making of the Term Loans but prior to the
Revolving Loan Commitment Termination Date,

            (a) each Lender that has a Percentage of the Revolving Loan
      Commitment in excess of zero will make loans (relative to such Lender, its
      "Revolving Loans") to the



                                      38
<PAGE>   46
      Borrower equal to such Lender's Percentage of the aggregate amount of the
      Borrowing or Borrowings of Revolving Loans requested by the Borrower to be
      made on such day. The Commitment of each Lender described in this Section
      2.1.2 is herein referred to as its "Revolving Loan Commitment". On the
      terms and subject to the conditions hereof, the Borrower may from time to
      time borrow, prepay and reborrow Revolving Loans.

            (b) the Swing Line Lender will make a loan (a "Swing Line Loan") to
      the Borrower equal to the principal amount of the Swing Line Loan
      requested by the Borrower to be made on such day. The Commitment of the
      Swing Line Lender described in this clause (b) is herein referred to as
      its "Swing Line Loan Commitment". On the terms and subject to the
      conditions hereof, the Borrower may from time to time borrow, prepay and
      reborrow Swing Line Loans.

            (c) At any time that no Default has occurred and is continuing, the
      Borrower may notify the Agents that the Borrower is requesting that, on
      the terms and subject to the conditions contained in this Agreement, the
      Lenders and/or other lenders not then a party to this Agreement provide up
      to an aggregate amount of $50,000,000 in additional Revolving Loan
      Commitments. Upon receipt of such notice, the Syndication Agent shall use
      its best commercially reasonable efforts to arrange for the Lenders or
      other financial institutions to provide such additional Revolving Loan
      Commitments; provided that the Syndication Agent will first offer each of
      the Lenders that then has a Percentage of the Revolving Loan Commitment a
      pro rata portion of any such additional Revolving Loan Commitment.
      Alternatively, any Lender may commit to provide the full amount of the
      requested additional Revolving Loan Commitment and then offer portions of
      such additional Revolving Loan Commitment to the other Lenders or other
      financial institutions, subject to the proviso to the immediately
      preceding sentence. Nothing contained in this clause (c) or otherwise in
      this Agreement is intended to commit any Lender or any Agent to provide
      any portion of any such additional Revolving Loan Commitments. If and to
      the extent that any Lenders and/or other lenders agree, in their sole
      discretion, to provide any such additional Revolving Loan Commitments, (i)
      the Revolving Loan Commitment Amount shall be increased by the amount of
      the additional Revolving Loan Commitments agreed to be so provided, (ii)
      the Percentages of the respective Lenders in respect of the Revolving Loan
      Commitment shall be proportionally adjusted, (iii) at such time and in
      such manner as the Borrower and the Syndication Agent shall agree (it
      being understood that the Borrower and the Agents will use their best
      commercially reasonable efforts to avoid the prepayment or assignment of
      any LIBO Rate Loan on a day other than the last day of the Interest Period
      applicable thereto), the Lenders shall assign and assume outstanding
      Revolving Loans and participations in outstanding Letters of Credit so as
      to cause the amounts of such Revolving Loans and participations in Letters
      of Credit held by each Lender to conform to the respective Percentages of
      the Revolving Loan Commitment of the Lenders and (iv) the Borrower shall
      execute and deliver any additional Notes or other amendments or
      modifications to this Agreement or any other Loan Document as the Agents
      may reasonably request.

      Date of an existing standby or commercial Letter of Credit previously
      issued hereunder to a date not later than the earlier of (x) the sixth
      anniversary of the Closing Date and (y) one year from the date of such
      extension; provided that, notwithstanding the terms of clause (ii) above,
      a Letter of Credit may, if required by the beneficiary thereof, contain
      "evergreen" provisions pursuant to which the Stated Expiry Date shall be
      automatically extended, unless notice to the contrary shall have been
      given to the beneficiary by the Issuer or the account party more than a
      specified period prior to the then existing Stated Expiry Date.

            (b) Each Existing Letter of Credit shall for all purposes of this
      Agreement be deemed to be a "Letter of Credit" issued hereunder on the
      Closing Date.

      SECTION 2.1.4. Lenders Not Permitted or Required to Make the Loans. No
Lender shall be permitted or required to, and the Borrower shall not request any
Lender to, make

            (a) any Term-A Loan or Term-B Loan (as the case may be) if, after
      giving effect thereto, the aggregate original principal amount of all the
      Term-A Loans or Term-B Loans (as the case may be) of such Lender would
      exceed such Lender's Percentage of the Term-A Loan Commitment Amount (in
      the case of Term-A Loans) or the Term-B Loan Commitment Amount (in the
      case of Term-B Loans);

            (b) any Revolving Loan if, after giving effect thereto, the

      Lender, together with such Lender's Percentage of the aggregate amount of
      all Letter of Credit Outstandings, and such Lender's Percentage of the
      outstanding principal amount of all Swing Line Loans, would exceed such
      Lender's Percentage of the lesser of (x) the then existing Revolving Loan
      Commitment Amount and (y) the then applicable Borrowing Base Amount; or

            (c) any Swing Line Loan if, after giving effect thereto, the
      aggregate outstanding principal amount of all Swing Line Loans would
      exceed the lesser of (x) the then existing Swing Line Loan Commitment
      Amount and (y) an amount equal to (i) the lesser of (A) the then
      applicable Borrowing Base Amount and (B) the then existing Revolving Loan
      Commitment Amount less (ii) the sum of the aggregate outstanding principal
      amount of all Revolving Loans and Letter of Credit Outstandings.

<PAGE>   48
      SECTION 2.1.5. Issuer Not Permitted or Required to Issue Letters of
Credit. No Issuer shall be permitted or required to issue, extend or renew any
Letter of Credit if, after giving effect thereto, (a) the aggregate amount of
all Letter of Credit Outstandings would exceed the Letter of Credit Commitment
Amount or (b) the sum of the aggregate amount of all Letter of Credit
Outstandings plus the aggregate principal amount of all Revolving Loans and
Swing Line Loans then outstanding would exceed the lesser of (x) the Revolving
Loan Commitment Amount and (y) the then applicable Borrowing Base Amount.

      SECTION 2.2. Reduction of the Commitment Amounts. The Commitment Amounts
are subject to reductions from time to time pursuant to this Section 2.2.

      SECTION 2.2.1. Optional. The Borrower may, from time to time on any
Business Day occurring after the time of the initial Credit Extension hereunder,
voluntarily reduce the Revolving Loan Commitment Amount; provided, however, that
all such reductions shall require at least three Business Days' prior notice to
the Administrative Agent and be permanent, and any partial reduction of any
Commitment Amount shall be in an aggregate amount of $500,000 or any larger
integral multiple of $100,000. Any such reduction of the Revolving Loan
Commitment Amount which reduces the Revolving Loan Commitment Amount below the
Letter of Credit Commitment Amount or the Swing Line Loan Commitment Amount
shall result in an automatic and corresponding reduction of the Letter of Credit
Commitment Amount or the Swing Line Loan Commitment Amount, as the case may be,
to an aggregate amount not in excess of the Revolving Loan Commitment Amount, as
so reduced, without any further action on the part of the Issuer or the Swing
Line Lender.

      SECTION 2.2.2. Mandatory. Following the prepayment in full of the Term
Loans, the Revolving Loan Commitment Amount shall, without any further action,
automatically and permanently be reduced on the date the Term Loans would
otherwise have been required to be prepaid on account of any Net Disposition
Proceeds, Net Debt Proceeds, Excess Cash Flow, Net Equity Proceeds or Casualty
Proceeds, in an amount equal to the amount by which the Term Loans would
otherwise have been required to be prepaid if Term Loans had been outstanding.
Any such reduction of the Revolving Loan Commitment Amount which reduces the
Revolving Loan Commitment Amount below the Letter of Credit Commitment Amount or
the Swing Line Loan Commitment Amount shall result in an automatic and
corresponding reduction of the Letter of Credit Commitment Amount or the Swing
Line Loan Commitment Amount, as the case may be, to an aggregate amount not in
excess of the Revolving Loan Commitment Amount, as so reduced, without any
further action on the part of the Issuer or the Swing Line Lender.

      SECTION 2.3. Borrowing Procedures and Funding Maintenance. Loans (other
than Swing Line Loans) shall be made by the Lenders in accordance with Section
2.3.1, and Swing Line Loans shall be made by the Swing Line Lender in accordance

Request to the Administrative Agent on or before 12:00 noon, New York time, on a
Business Day, the Borrower may from time to time irrevocably request, on not
less than one Business Day's notice



                                      41
<PAGE>   49
(in the case of Base Rate Loans) or three Business Days' notice (in the case of
LIBO Rate Loans) nor more than five Business Days' notice (in the case of any
Loans), that a Borrowing be made in an aggregate amount of $500,000 or any
larger integral multiple of $100,000, or in the unused amount of the applicable
Commitment. No Borrowing Request shall be required, and the minimum aggregate
amounts specified under this Section 2.3.1 shall not apply, in the case of
Revolving Loans made under clause (b) of Section 2.3.2 to refund Refunded Swing
Line Loans or deemed made under Section 2.6.2 in respect of unreimbursed
Disbursements. On the terms and subject to the conditions of this Agreement,
each Borrowing shall be comprised of the type of Loans, and shall be made on the
Business Day, specified in such Borrowing Request. On or before 11:00 a.m., New
York time, on such Business Day each Lender shall deposit with the
Administrative Agent same day funds in an amount equal to such Lender's
Percentage of the requested Borrowing. Such deposit will be made to an account
which the Administrative Agent shall specify from time to time by notice to the
Lenders. To the extent funds are received from the Lenders, the Administrative
Agent shall make such funds available to the Borrower by wire transfer to the
accounts the Borrower shall have specified in its Borrowing Request. No Lender's
obligation to make any Loan shall be affected by any other Lender's failure to
make any Loan.

      SECTION 2.3.2. Swing Line Loans. (a) By telephonic notice, promptly
followed (within one Business Day) by the delivery of a confirming Borrowing
Request, to the Swing Line Lender on or before 1:00 p.m., New York City time, on
the Business Day the proposed Swing Line Loan is to be made, the Borrower may
from time to time irrevocably request that a Swing Line Loan be made by the
Swing Line Lender in a minimum principal amount of $50,000 or any larger
integral multiple of $10,000. All Swing Line Loans shall be made as Base Rate
Loans and shall not be entitled to be converted into LIBO Rate Loans. The
proceeds of each Swing Line Loan shall be made available by the Swing Line
Lender, by 2:00 p.m., New York City time, on the Business Day telephonic notice
is received by it as provided in this clause (a), to the Borrower by wire
transfer to the account the Borrower shall have specified in its notice
therefor.

      (b) If (i) any Swing Line Loan shall be outstanding for more than four
Business Days or (ii) any Default shall occur and be continuing, each Lender
with a Revolving Loan Commitment (other than the Swing Line Lender) irrevocably
agrees that it will, at the request of the Swing Line Lender and upon notice
from the Administrative Agent, unless such Swing Line Loan shall have been
earlier repaid in full, make a Revolving Loan (which shall initially be funded
as a Base Rate Loan) in an amount equal to such Lender's Percentage of the
aggregate principal amount of all such Swing Line Loans then outstanding (such
outstanding Swing Line Loans hereinafter referred to as the "Refunded Swing Line
Loans"); provided, that the Swing Line Lender shall not request, and no Lender
with a Revolving Loan Commitment shall make, any Refunded Swing Line Loan if,
after giving effect to the making of such Refunded Swing Line Loan, the sum of
all Swing Line Loans and Revolving Loans made by such Lender, plus such Lender's
Percentage of the aggregate amount of all Letter of Credit Outstandings, would
exceed such Lender's Percentage of the then existing Revolving Loan Commitment
Amount. On or before 12:00 noon (New York time) on the first Business Day
following receipt by each Lender



                                      42
<PAGE>   50
of a request to make Revolving Loans as provided in the preceding sentence, each
such Lender with a Revolving Loan Commitment shall deposit in an account
specified by the Swing Line Lender the amount so requested in same day funds and
such funds shall be applied by the Swing Line Lender to repay the Refunded Swing
Line Loans. At the time the aforementioned Lenders make the above referenced
Revolving Loans, the Swing Line Lender shall be deemed to have made, in
consideration of the making of the Refunded Swing Line Loans, a Revolving Loan
in an amount equal to the Swing Line Lender's Percentage of the aggregate
principal amount of the Refunded Swing Line Loans. Upon the making (or deemed
making, in the case of the Swing Line Lender) of any Revolving Loans pursuant to
this clause (b), the amount so funded shall become outstanding under such
Lender's Revolving Note and shall no longer be owed under the Swing Line Note.
All interest payable with respect to any Revolving Loans made (or deemed made,
in the case of the Swing Line Lender) pursuant to this clause (b) shall be
appropriately adjusted to reflect the period of time during which the Swing Line
Lender had outstanding Swing Line Loans in respect of which such Revolving Loans
were made. Each Lender's obligation (in the case of Lenders with a Revolving
Loan Commitment) to make the Revolving Loans referred to in this clause (b)
shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, (i) any set-off, counterclaim,
recoupment, defense or other right which such Lender may have against the Swing
Line Lender, the Borrower or any other Person for any reason whatsoever; (ii)
the occurrence or continuance of any Default; (iii) any adverse change in the
condition (financial or otherwise) of the Borrower; (iv) the acceleration or
maturity of any Loans or the termination of any Commitment after the making of
any Swing Line Loan; (v) any breach of this Agreement or any other Loan Document
by the Borrower or any Lender; or (vi) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing.

      SECTION 2.4. Continuation and Conversion Elections. By delivering a
Continuation/Conversion Notice to the Administrative Agent on or before 12:00
noon, New York time, on a Business Day, the Borrower may from time to time
irrevocably elect, on not less than one Business Day's notice (in the case of a
conversion of LIBO Rate Loans to Base Rate Loans) or three Business Days' notice
(in the case of a continuation of LIBO Rate Loans or a conversion of Base Rate
Loans into LIBO Rate Loans) nor more than five Business Days' notice (in the
case of any Loans) that all, or any portion in a minimum amount of $500,000 or
any larger integral multiple of $100,000, be, in the case of Base Rate Loans,
converted into LIBO Rate Loans or, in the case of LIBO Rate Loans, converted
into Base Rate Loans or continued as LIBO Rate Loans (in the absence of delivery
of a Continuation/Conversion Notice with respect to any LIBO Rate Loan at least
three Business Days before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically
convert to a Base Rate Loan); provided, however, that (x) each such conversion
or continuation shall be pro rated among the applicable outstanding Loans of the
relevant Lenders, and (y) no portion of the outstanding principal amount of any
Loans may be continued as, or be converted into, LIBO Rate Loans when any
Default has occurred and is continuing.

      SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or



                                      43
<PAGE>   51
Affiliates (or an international banking facility created by such Lender) to make
or maintain such LIBO Rate Loan, so long as such action does not result in
increased costs to the Borrower; provided, however, that such LIBO Rate Loan
shall nonetheless be deemed to have been made and to be held by such Lender, and
the obligation of the Borrower to repay such LIBO Rate Loan shall nevertheless
be to such Lender for the account of such foreign branch, Affiliate or
international banking facility; and provided, further, however, that, except for
purposes of determining whether any such increased costs are payable by the
Borrower, such Lender shall cause such foreign branch, Affiliate or
international banking facility to comply with the applicable provisions of
clause (b) of Section 4.6 with respect to such LIBO Rate Loan. In addition, the
Borrower hereby consents and agrees that, for purposes of any determination to
be made for purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall be conclusively
assumed that each Lender elected to fund all LIBO Rate Loans by purchasing
Dollar deposits in its LIBOR Office's interbank Eurodollar market.

      SECTION 2.6. Issuance Procedures. By delivering to the Administrative
Agent an Issuance Request on or before 12:00 noon, New York time, on a Business
Day, the Borrower may, from time to time irrevocably request, on not less than
three nor more than ten Business Days' notice (or such shorter or longer notice
as may be acceptable to the Issuer), in the case of an initial issuance of a
Letter of Credit, and not less than three nor more than ten Business Days'
notice (unless a shorter or longer notice period is acceptable to the Issuer)
prior to the then existing Stated Expiry Date of a Letter of Credit, in the case
of a request for the extension of the Stated Expiry Date of a Letter of Credit,
that the Issuer issue, or extend the Stated Expiry Date of, as the case may be,
an irrevocable Letter of Credit on behalf of the Borrower (whether issued for
the account of or on behalf of the Borrower or any of its Subsidiaries) in such
form as may be requested by the Borrower and approved by the Issuer, for the
purposes described in Section 7.1.9. Notwithstanding anything to the contrary
contained herein or in any separate application for any Letter of Credit, the
Borrower hereby acknowledges and agrees that it shall be obligated to reimburse
the Issuer upon each Disbursement paid under a Letter of Credit, and it shall be
deemed to be the obligor for purposes of each such Letter of Credit issued
hereunder (whether the account party on such Letter of Credit is the Borrower or
a Subsidiary of the Borrower). Upon receipt of an Issuance Request, the
Administrative Agent shall promptly notify the Issuer and each Lender thereof.
Each Letter of Credit shall by its terms be stated to expire on a date (its
"Stated Expiry Date") no later than the earlier to occur of (i) the sixth
anniversary of the Closing Date or (ii) one year from the date of its issuance;
provided that, notwithstanding the terms of clause (ii) above, a Letter of
Credit may, if required by the beneficiary thereof, contain "evergreen"
provisions pursuant to which the Stated Expiry Date shall be automatically
extended, unless notice to the contrary shall have been given to the beneficiary
by the Issuer or the account party more than a specified period prior to the
then existing Stated Expiry Date. The Issuer will make available to the
beneficiary thereof the original of each Letter of Credit which it issues
hereunder.

      SECTION 2.6.1. Other Lenders' Participation. Upon the issuance of each
Letter of Credit issued by the Issuer pursuant hereto, and without further
action, each Lender (other than the Issuer) that has a Revolving Loan Commitment
shall be deemed to have irrevocably



                                      44
<PAGE>   52
purchased from the Issuer, to the extent of its Percentage in respect of
Revolving Loans, and the Issuer shall be deemed to have irrevocably granted and
sold to such Lender a participation interest in such Letter of Credit (including
the Contingent Liability and any Reimbursement Obligation and all rights with
respect thereto), and such Lender shall, to the extent of its Percentage in
respect of Revolving Loans, be responsible for reimbursing promptly (and in any
event within one Business Day) the Issuer for Reimbursement Obligations which
have not been reimbursed by the Borrower in accordance with Section 2.6.3. In
addition, such Lender shall, to the extent of its Percentage in respect of
Revolving Loans, be entitled to receive a ratable portion of the Letter of
Credit fees payable pursuant to Section 3.3.3 with respect to each Letter of
Credit and of interest payable pursuant to Section 3.2 with respect to any
Reimbursement Obligation. To the extent that any Lender has reimbursed the
Issuer for a Disbursement as required by this Section, such Lender shall be
entitled to receive its ratable portion of any amounts subsequently received
(from the Borrower or otherwise) in respect of such Disbursement.

      SECTION 2.6.2. Disbursements; Conversion to Revolving Loans. The Issuer
will notify the Borrower and the Administrative Agent promptly of the
presentment for payment of any drawing under any Letter of Credit issued by the
Issuer, together with notice of the date (the "Disbursement Date") such payment
shall be made (each such payment, a "Disbursement"). Subject to the terms and
provisions of such Letter of Credit and this Agreement, the Issuer shall make
such payment to the beneficiary (or its designee) of such Letter of Credit.
Prior to 12:30 p.m., New York time, on the first Business Day following the
Disbursement Date (the "Disbursement Due Date"), the Borrower will reimburse the
Administrative Agent, for the account of the Issuer, for all amounts which the
Issuer has disbursed under such Letter of Credit, together with interest thereon
at the rate per annum otherwise applicable to Revolving Loans (made as Base Rate
Loans) from and including the Disbursement Date to but excluding the
Disbursement Due Date and, thereafter (unless such Disbursement is converted
into a Base Rate Loan on the Disbursement Due Date), at a rate per annum equal
to the rate per annum then in effect with respect to overdue Revolving Loans
(made as Base Rate Loans) pursuant to Section 3.2.2 for the period from the
Disbursement Due Date through the date of such reimbursement; provided, however,
that, if no Default shall have then occurred and be continuing, unless the
Borrower has notified the Administrative Agent no later than one Business Day
prior to the Disbursement Due Date that it will reimburse the Issuer for the
applicable Disbursement, then the amount of the Disbursement shall be deemed to
be a Borrowing of Revolving Loans constituting Base Rate Loans and following the
giving of notice thereof by the Administrative Agent to the Lenders, each Lender
with a Revolving Loan Commitment (other than the Issuer) will deliver to the
Issuer on the Disbursement Due Date immediately available funds in an amount
equal to such Lender's Percentage of such Borrowing. Each conversion of
Disbursement amounts into Revolving Loans shall constitute a representation and
warranty by the Borrower that on the date of the making of such Revolving Loans
all of the statements set forth in Section 5.2.1 are true and correct.

      SECTION 2.6.3. Reimbursement. The obligation (a "Reimbursement
Obligation") of the Borrower under Section 2.6.2 to reimburse the Issuer with
respect to each Disbursement (including interest thereon) not converted into a
Base Rate Loan pursuant to Section 2.6.2, and,



                                      45
<PAGE>   53
upon the Borrower failing or electing not to reimburse the Issuer and the giving
of notice thereof by the Administrative Agent to the Lenders, each Lender's (to
the extent it has a Revolving Loan Commitment) obligation under Section 2.6.1 to
reimburse the Issuer or fund its Percentage of any Disbursement converted into a
Base Rate Loan, shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
which the Borrower or such Lender, as the case may be, may have or have had
against the Issuer or any such Lender, including any defense based upon the
failure of any Disbursement to conform to the terms of the applicable Letter of
Credit (if, in the Issuer's good faith opinion, such Disbursement is determined
to be appropriate) or any non-application or misapplication by the beneficiary
of the proceeds of such Letter of Credit; provided, however, that after paying
in full its Reimbursement Obligation hereunder, nothing herein shall adversely
affect the right of the Borrower or such Lender, as the case may be, to commence
any proceeding against the Issuer for any wrongful Disbursement made by the
Issuer under a Letter of Credit as a result of acts or omissions constituting
gross negligence or willful misconduct on the part of the Issuer.

      SECTION 2.6.4. Deemed Disbursements. Upon the occurrence and during the
continuation of any Event of Default of the type described in clauses (b)
through (d) of Section 8.1.9 with respect to any Obligor (other than immaterial
Subsidiaries) or, with notice from the Administrative Agent acting at the
direction of the Required Lenders, upon the occurrence and during the
continuation of any other Event of Default,

            (a) an amount equal to that portion of all Letter of Credit
      Outstandings attributable to the then aggregate amount which is undrawn
      and available under all Letters of Credit issued and outstanding shall,
      without demand upon or notice to the Borrower or any other Person, be
      deemed to have been paid or disbursed by the Issuer under such Letters of
      Credit (notwithstanding that such amount may not in fact have been so paid
      or disbursed); and

            (b) upon notification by the Administrative Agent to the Borrower of
      its obligations under this Section, the Borrower shall be immediately
      obligated to reimburse the Issuer for the amount deemed to have been so
      paid or disbursed by the Issuer.

Any amounts so payable by the Borrower pursuant to this Section shall be
deposited in cash with the Administrative Agent and held as collateral security
for the Obligations in connection with the Letters of Credit issued by the
Issuer. At such time as the Events of Default giving rise to the deemed
disbursements hereunder shall have been cured or waived, the Administrative
Agent shall return to the Borrower all amounts then on deposit with the
Administrative Agent pursuant to this Section, together with accrued interest at
the Federal Funds Rate, which have not been applied to the satisfaction of such
Obligations.

      SECTION 2.6.5. Nature of Reimbursement Obligations. The Borrower and, to
the extent set forth in Section 2.6.1, each Lender with a Revolving Loan
Commitment, shall assume all risks of the acts, omissions or misuse of any
Letter of Credit by the beneficiary thereof. The



                                      46
<PAGE>   54
Issuer (except to the extent of its own gross negligence or willful misconduct)
shall not be responsible for:

            (a) the form, validity, sufficiency, accuracy, genuineness or legal
      effect of any Letter of Credit or any document submitted by any party in
      connection with the application for and issuance of a Letter of Credit,
      even if it should in fact prove to be in any or all respects invalid,
      insufficient, inaccurate, fraudulent or forged;

            (b) the form, validity, sufficiency, accuracy, genuineness or legal
      effect of any instrument transferring or assigning or purporting to
      transfer or assign a Letter of Credit or the rights or benefits thereunder
      or the proceeds thereof in whole or in part, which may prove to be invalid
      or ineffective for any reason;

            (c) failure of the beneficiary to comply fully with conditions
      required in order to demand payment under a Letter of Credit;

            (d) errors, omissions, interruptions or delays in transmission or
      delivery of any messages, by mail, cable, telegraph, telex or otherwise;
      or

            (e) any loss or delay in the transmission or otherwise of any
      document or draft required in order to make a Disbursement under a Letter
      of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to the Issuer or any Lender with a Revolving Loan
Commitment hereunder. In furtherance and extension and not in limitation or
derogation of any of the foregoing, any action taken or omitted to be taken by
the Issuer in good faith (and not constituting gross negligence or willful
misconduct) shall be binding upon the Borrower, each Obligor and each such
Lender, and shall not put the Issuer under any resulting liability to the
Borrower, any Obligor or any such Lender, as the case may be.

      SECTION 2.7.  Register; Notes.

            (a) Each Lender may 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, including the amounts
      of principal and interest payable and paid to such Lender from time to
      time hereunder. In the case of a Lender that does not request, pursuant to
      clause (b)(ii) below, execution and delivery of a Note evidencing the
      Loans made by such Lender to the Borrower, such account or accounts shall,
      to the extent not inconsistent with the notations made by the
      Administrative Agent in the Register, be conclusive and binding on the
      Borrower absent manifest error; provided, however, that the failure of any
      Lender to maintain such account or accounts shall not limit or otherwise
      affect any Obligations of the Borrower or any other Obligor.




                                      47

<PAGE>   55
            (b)(i) The Borrower hereby designates the Administrative Agent to
      serve as the Borrower's agent, solely for the purpose of this clause (b),
      to maintain a register (the "Register") on which the Administrative Agent
      will record each Administrative Lender's Commitment, the Loans made by
      each Lender and each repayment in respect of the principal amount of the
      Loans of each Lender and annexed to which the Administrative Agent shall
      retain a copy of each Lender Assignment Agreement delivered to the
      Administrative Agent pursuant to Section 10.11.1. Failure to make any
      recordation, or any error in such recordation, shall not affect the
      Borrower's obligation in respect of such Loans. The entries in the
      Register shall be conclusive, in the absence of manifest error, and the
      Borrower, the Administrative Agent and the Lenders shall treat each Person
      in whose name a Loan (and as provided in clause (ii) the Note evidencing
      such Loan, if any) is registered as the owner thereof for all purposes of
      this Agreement, notwithstanding notice or any provision herein to the
      contrary. A Lender's Commitment and the Loans made pursuant thereto may be
      assigned or otherwise transferred in whole or in part only by registration
      of such assignment or transfer in the Register. Any assignment or transfer
      of a Lender's Commitment or the Loans made pursuant thereto shall be
      registered in the Register only upon delivery to the Administrative Agent
      of a Lender Assignment Agreement duly executed by the assignor thereof. No
      assignment or transfer of a Lender's Commitment or the Loans made pursuant
      thereto shall be effective unless such assignment or transfer shall have
      been recorded in the Register by the Administrative Agent as provided in
      this Section.

            (ii) The Borrower agrees that, upon the request to the
      Administrative Agent by any Lender, the Borrower will execute and deliver
      to such Lender, as applicable, a Revolving Note, a Term-A Note and a
      Term-B Note and a Swing Line Note evidencing the Loans made by such
      Lender. The Borrower hereby irrevocably authorizes each Lender to make (or
      cause to be made) appropriate notations on the grid attached to such
      Lender's Notes (or on any continuation of such grid), which notations, if
      made, shall evidence, inter alia, the date of, the outstanding principal
      amount of, and the interest rate and Interest Period applicable to the
      Loans evidenced thereby. Such notations shall, to the extent not
      inconsistent with the notations made by the Administrative Agent in the
      Register, be conclusive and binding on the Borrower absent manifest error;
      provided, however, that the failure of any Lender to make any such
      notations shall not limit or otherwise affect any Obligations of the
      Borrower or any other Obligor. The Loans evidenced by any such Note and
      interest thereon shall at all times (including after assignment pursuant
      to Section 10.11.1) be represented by one or more Notes payable to the
      order of the payee named therein and its registered assigns. A Note and
      the obligation evidenced thereby may be assigned or otherwise transferred
      in whole or in part only by registration of such assignment or transfer of
      such Note and the obligation evidenced thereby in the Register (and each
      Note shall expressly so provide). Any assignment or transfer of all or
      part of an obligation evidenced by a Note shall be registered in the
      Register only upon surrender for registration of assignment or transfer of
      the Note evidencing such obligation, accompanied by a Lender Assignment
      Agreement duly executed by the assignor thereof, and thereupon,


                                       48
<PAGE>   56
      if requested by the assignee, one or more new Notes shall be issued to the
      designated assignee and the old Note shall be returned by the
      Administrative Agent to the Borrower marked "exchanged". No assignment of
      a Note and the obligation evidenced thereby shall be effective unless it
      shall have been recorded in the Register by the Administrative Agent as
      provided in this Section.


                                   ARTICLE III

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

      SECTION 3.1. Repayments and Prepayments; Application.

      SECTION 3.1.1. Repayments and Prepayments. The Borrower shall repay in
full the unpaid principal amount of each Loan upon the Stated Maturity Date
therefor. Prior thereto, the Borrower

            (a) may, from time to time on any Business Day, make a voluntary
      prepayment, in whole or in part, of the outstanding principal amount of
      any

                  (i) Loans (other than Swing Line Loans); provided, however,
            that

                        (A) any such prepayment of the Term-A Loans or Term-B
                  Loans shall be made pro rata among Term-A Loans and Term-B
                  Loans, as applicable, of the same type and, if applicable,
                  having the same Interest Period of all Lenders that have made
                  such Term-A Loans or Term-B Loans, and any such prepayment of
                  Revolving Loans shall be made pro rata among the Revolving
                  Loans of the same type and, if applicable, having the same
                  Interest Period of all Lenders that have made such Revolving
                  Loans;

                        (B) the Borrower shall comply with Section 4.4 in the
                  event that any LIBO Rate Loan is prepaid on any day other than
                  the last day of the Interest Period for such Loan;

                        (C) all such voluntary prepayments shall require at
                  least one Business Day's notice in the case of Base Rate
                  Loans, three Business Days' notice in the case of LIBO Rate
                  Loans, but no more than five Business Days' notice in the case
                  of any Loans, in each case in writing to the Administrative
                  Agent; and

                        (D) all such voluntary partial prepayments shall be in
                  an aggregate amount of $500,000 or any larger integral
                  multiple of $100,000 or in the


                                       49
<PAGE>   57
                  aggregate principal amount of all Loans of the applicable
                  Tranche and type then outstanding; or

                  (ii) Swing Line Loans, provided that

                        (A) all such voluntary prepayments shall require prior
                  telephonic notice to the Swing Line Lender on or before 1:00
                  p.m., New York City time, on the day of such prepayment (such
                  notice to be confirmed in writing by the Borrower within 24
                  hours thereafter); and

                        (B) all such voluntary partial prepayments shall be in
                  an aggregate amount of $50,000 and an integral multiple of
                  $10,000 or in the aggregate principal amount of all Swing Line
                  Loans then outstanding;

            (b) shall, on each date when any reduction in the then applicable
      Borrowing Base Amount shall become effective, make a mandatory prepayment
      of Revolving Loans or all Swing Line Loans (or both) and (if necessary)
      deposit with the Administrative Agent cash collateral for Letter of Credit
      Outstandings, in an aggregate amount equal to the excess, if any, of the
      sum of (i) the aggregate outstanding principal amount of all Revolving
      Loans and Swing Line Loans and (ii) the aggregate amount of all Letter of
      Credit Outstandings over the then applicable Borrowing Base Amount;

            (c) shall, no later than five Business Days following the delivery
      by the Borrower of its annual audited financial reports required pursuant
      to clause (b) of Section 7.1.1 (beginning with the financial reports
      delivered in respect of the 1998 Fiscal Year), deliver to the
      Administrative Agent a calculation of the Excess Cash Flow for the Fiscal
      Year (or, in the case of the 1998 Fiscal Year, the period from August 31,
      1997 through June 30, 1998) last ended and, no later than five Business
      Days following the delivery of such calculation, make a mandatory
      prepayment of the Term Loans in an amount equal to (i) 50% of the Excess
      Cash Flow (if any) for such Fiscal Year (or period) less (ii) the
      aggregate amount of all voluntary prepayments of the principal of the Term
      Loans actually made in such Fiscal Year pursuant to clause (a) of Section
      3.1.1, to be applied as set forth in Section 3.1.2; provided, however,
      that no such prepayment shall be required to be made to the extent that
      the amount of Debt as reduced by giving effect to such prepayment would
      result in a Leverage Ratio of 3.50:1 or less as of the end of the
      immediately preceding Fiscal Quarter;

            (d) shall, not later than one Business Day following the receipt of
      any Net Disposition Proceeds or Net Debt Proceeds by the Borrower or any
      of its Restricted Subsidiaries, deliver to the Administrative Agent a
      calculation of the amount of such Net Disposition Proceeds or Net Debt
      Proceeds, as the case may be, and, to the extent the amount of such Net
      Disposition Proceeds or Net Debt Proceeds, as the case may be, with
      respect to any single transaction or series of related transactions,
      exceeds $2,500,000, make a mandatory prepayment of the Term Loans in an
      amount equal to 100% of such


                                       50
<PAGE>   58
      Net Disposition Proceeds or Net Debt Proceeds, as the case may be, to be
      applied as set forth in Section 3.1.2; provided, that no mandatory
      prepayment on account of such Net Disposition Proceeds shall be required
      under this clause if the Borrower informs the Agents no later than 30 days
      following the receipt of any Net Disposition Proceeds of its or its
      Restricted Subsidiary's good faith intention to apply such Net Disposition
      Proceeds to the acquisition of other assets or property consistent with
      the DecisionOne Business (including by way of merger or investment) within
      365 days following the receipt of such Net Disposition Proceeds, with the
      amount of such Net Disposition Proceeds unused after such 365 day period
      being applied to the Loans as set forth in Section 3.1.2;

            (e) shall, concurrently with the receipt of any Net Equity Proceeds
      by the Borrower or any of its Restricted Subsidiaries, deliver to the
      Administrative Agent a calculation of the amount of such Net Equity
      Proceeds, and no later than five Business Days following the delivery of
      such calculation, and, to the extent that the amount of such Net Equity
      Proceeds with respect to any single transaction or series of related
      transactions exceeds $2,500,000, make a mandatory prepayment of the Term
      Loans in an amount equal to 50% of such Net Equity Proceeds to be applied
      as set forth in Section 3.1.2;

            (f) shall, concurrently with the receipt by the Borrower or any of
      its Restricted Subsidiaries of any Casualty Proceeds in excess of
      $2,500,000 (individually or in the aggregate over the course of a Fiscal
      Year), deposit such Casualty Proceeds in an account maintained with the
      Administrative Agent and within 60 days following the receipt by the
      Borrower or any of its Restricted Subsidiaries of such Casualty Proceeds,
      direct the Administrative Agent to apply such Casualty Proceeds to prepay
      the Term Loans in an amount equal to 100% of such Casualty Proceeds, to be
      applied as set forth in Section 3.1.2; provided, that no mandatory
      prepayment on account of Casualty Proceeds shall be required under this
      clause if the Borrower informs the Agents no later than 60 days following
      the occurrence of the Casualty Event resulting in such Casualty Proceeds
      of its or its Restricted Subsidiary's good faith intention to apply such
      Casualty Proceeds to the rebuilding or replacement of the damaged,
      destroyed or condemned assets or property and in fact uses such Casualty
      Proceeds to rebuild or replace the damaged, destroyed or condemned assets
      or property within 365 days following the receipt of such Casualty

      excess, if any, of the sum of (i) the aggregate outstanding principal
      amount of all Revolving Loans and Swing Line Loans and (ii) the aggregate
      amount of all Letter of Credit Outstandings over the Revolving Loan
      Commitment Amount as so reduced;

      Date of any Loans or Obligations pursuant to Section 8.2 or Section 8.3,
      repay all outstanding Loans and other Obligations, unless, pursuant to
      Section 8.3, only a portion of all Loans and other Obligations are so
      accelerated (in which case the portion so accelerated shall be so
      prepaid).


                                       52
<PAGE>   60
      Each prepayment of any Loans made pursuant to this Section shall be
without premium or penalty, except as may be required by Section 4.4. No
prepayment of principal of any Revolving Loans or Swing Line Loans pursuant to
clause (a), (b) or (j) of this Section 3.1.1 shall cause a reduction in the
Revolving Loan Commitment Amount or the Swing Line Loan Commitment Amount, as
the case may be.

      SECTION 3.1.2. Application. (a) Subject to clause (b) below, each
prepayment or repayment of principal of the Loans of any Tranche shall be
applied, to the extent of such prepayment or repayment, first, to the principal
amount thereof being maintained as Base Rate Loans, and second, to the principal
amount thereof being maintained as LIBO Rate Loans.

      (b) Each prepayment of Term Loans made pursuant to clauses (a), (c), (d),
(e), and (f) of Section 3.1.1 shall be applied, (i) on a pro rata basis, to the
outstanding principal amount of all remaining Term-A Loans and Term-B Loans and
(ii) in respect of each Tranche of Term Loans, in direct order of maturity of
the remaining scheduled quarterly amortization payments in respect thereof,
until all such Term-A Loans and Term-B Loans have been paid in full; provided,
however, that if the Borrower at any time elects in writing, in its sole
discretion, to permit any Lender that has Term-B Loans to decline to have such
Loans prepaid, then any Lender having Term-B Loans outstanding may, by
delivering a notice to the Agents at least one Business Day prior to the date
that such prepayment is to be made, decline to have such Loans prepaid with the
amounts set forth above, in which case 50% of the amounts that would have been
applied to a prepayment of such Lender's Term-B Loans shall instead be applied
to a prepayment of the Term-A Loans (until paid in full), with the balance being
retained by the Borrower.

      SECTION 3.2. Interest Provisions. Interest on the outstanding principal
amount of the Loans shall accrue and be payable in accordance with this Section
3.2.

      SECTION 3.2.1. Rates.

       (a) Each Base Rate Loan shall accrue interest on the unpaid principal
amount thereof for each day from and including the day upon which such Loan was
made or converted to a Base Rate Loan to but excluding the date such Loan is
repaid or converted to a LIBO Rate Loan at a rate per annum equal to the sum of
the Alternate Base Rate for such day plus the Applicable Margin for such Loan on
such day.

      (b) Each LIBO Rate Loan shall accrue interest on the unpaid principal
amount thereof for each day during each Interest Period applicable thereto at a
rate per annum equal to the sum of the LIBO Rate (Reserve Adjusted) for such
Interest Period plus the Applicable Margin for such Loan on such day.

All LIBO Rate Loans shall bear interest from and including the first day of the
applicable Interest Period to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such LIBO Rate Loan.


                                       53
<PAGE>   61
      SECTION 3.2.2. Post-Maturity Rates. After the date any principal amount of
any Loan shall have become due and payable (whether on the applicable Stated
Maturity Date, upon acceleration or otherwise), or any other monetary Obligation
(other than overdue Reimbursement Obligations which shall bear interest as
provided in Section 2.6.2) of the Borrower shall have become due and payable,
the Borrower shall pay, but only to the extent permitted by law, interest (after
as well as before judgment) on such amounts at a rate per annum equal to (a) in
the case of any overdue principal of Loans, overdue interest thereon, overdue
commitment fees or other overdue amounts in respect of Loans or other
obligations (or the related Commitments) under a particular Tranche, the rate
that would otherwise be applicable to Base Rate Loans under such Tranche
pursuant to Section 3.2.1 plus 2% and (b) in the case of other overdue monetary
Obligations, the rate that would otherwise be applicable to Revolving Loans that
were Base Rate Loans plus 2%.

      SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be
payable, without duplication:

            (a) on the Stated Maturity Date therefor;

            (b) in the case of a LIBO Rate Loan, on the date of any payment or
      prepayment, in whole or in part, of principal outstanding on such Loan, to
      the extent of the unpaid interest accrued through such date on the
      principal so paid or prepaid;

            (c) with respect to Base Rate Loans, on each Quarterly Payment Date
      occurring after the date of the initial Borrowing hereunder;

            (d) with respect to LIBO Rate Loans, on the last day of each
      applicable Interest Period (and, if such Interest Period shall exceed
      three months, at intervals of three months after the first day of such
      Interest Period);

            (e) with respect to the principal amount of any Base Rate Loans
      converted into LIBO Rate Loans on a day when interest would not otherwise
      have been payable pursuant to clause (c), on the date of such conversion;
      and

            (f) on that portion of any Loans the Stated Maturity Date of which
      is accelerated pursuant to Section 8.2 or Section 8.3, immediately upon
      such acceleration.

Interest accrued on Loans, Reimbursement Obligations or other monetary
Obligations arising under this Agreement or any other Loan Document after the
date such amount is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise) shall be payable upon demand.

      SECTION 3.3. Fees. The Borrower agrees to pay the fees set forth in this
Section 3.3. All such fees shall be non-refundable.


                                       54
<PAGE>   62
      SECTION 3.3.1. Commitment Fee. The Borrower agrees to pay to the
Administrative Agent for the account of each Lender that has a Revolving Loan
Commitment, for each day during the period (including any portion thereof when
any of the Lenders' Revolving Loan Commitments are suspended by reason of the
Borrower's inability to satisfy any condition of Article V) commencing on the
Closing Date and continuing to but excluding the Revolving Loan Commitment
Termination Date, a commitment fee on such Lender's Percentage of the unused
portion, whether or not then available, of the Revolving Loan Commitment Amount
(net of Letter of Credit Outstandings) for such day at a rate per annum equal to
the Applicable Commitment Fee for such day. Such commitment fee shall be payable
by the Borrower in arrears on each Quarterly Payment Date, commencing with the
first such day following the Closing Date, and on the Revolving Loan Commitment
Termination Date. The making of Swing Line Loans shall not constitute usage of
the Revolving Loan Commitment with respect to the calculation of commitment fees
to be paid by the Borrower to the Lenders. Any term or provision hereof to the
contrary notwithstanding, commitment fees payable for any period prior to the
Closing Date shall be payable in accordance with the Fee Letter. Payments by the
Borrower to the Swing Line Lender in respect of accrued interest on Swing Line
Loans shall be net of the commitment fee payable in respect of the Swing Line
Lender's Revolving Loan Commitment.

      SECTION 3.3.2. Administrative Agent Fee. The Borrower agrees to pay an
annual administration fee to the Administrative Agent, for its own account, in
the amount set forth in the Administrative Agent's Fee Letter, payable in
advance on the Closing Date and quarterly thereafter.

      SECTION 3.3.3. Letter of Credit Fee. The Borrower agrees to pay to the
Administrative Agent, for the pro rata account of the Issuer and each other
Lender that has a Revolving Loan Commitment, a Letter of Credit fee for each day
on which there shall be any Letters of Credit outstanding in an amount equal to
(i) with respect to each standby Letter of Credit, a rate per annum equal to the
then Applicable Margin for Revolving Loans maintained as LIBO Rate Loans, minus
1/8 of 1% per annum, multiplied by the Stated Amount of each such Letter of
Credit; and (ii) with respect to each documentary Letter of Credit, 1.25% per
annum multiplied by the Stated Amount of each such Letter of Credit, such fees
being payable quarterly in arrears on each Quarterly Payment Date. The Borrower
further agrees to pay to the Issuer quarterly in arrears on each Quarterly
Payment Date, an issuance fee as specified in the Administrative Agent's Fee
Letter.


                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

      SECTION 4.1. LIBO Rate Lending Unlawful. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrower and the Lenders,
be conclusive and binding on the Borrower) that the introduction of or any
change in or in the interpretation of any


                                       55
<PAGE>   63
law, in each case after the date upon which such Lender shall have become a
Lender hereunder, makes it unlawful, or any central bank or other governmental
authority asserts, after such date, that it is unlawful, for such Lender to
make, continue or maintain any Loan as, or to convert any Loan into, a LIBO Rate
Loan, the obligations of such Lender to make, continue, maintain or convert any
Loans as or to LIBO Rate Loans shall, upon such determination, forthwith be
suspended until such Lender shall notify the Administrative Agent that the
circumstances causing such suspension no longer exist (with the date of such
notice being the "Reinstatement Date"), and (i) all LIBO Rate Loans previously
made by such Lender shall automatically convert into Base Rate Loans at the end
of the then current Interest Periods with respect thereto or sooner, if required
by such law or assertion and (ii) all Loans thereafter made by such Lender and
outstanding prior to the Reinstatement Date shall be made as Base Rate Loans,
with interest thereon being payable on the same date that interest is payable
with respect to the corresponding Borrowing of LIBO Rate Loans made by Lenders
not so affected.

      SECTION 4.2. Deposits Unavailable. If the Administrative Agent shall have
determined that (i) Dollar deposits in the relevant amount and for the relevant
Interest Period are not available to the Administrative Agent in its relevant
market, or (ii) by reason of circumstances affecting the Administrative Agent's
relevant market, adequate means do not exist for ascertaining the interest rate
applicable hereunder to LIBO Rate Loans, then, upon notice from the
Administrative Agent to the Borrower and the Lenders, the obligations of all
Lenders under Section 2.3 and Section 2.4 to make or continue any Loans as, or
to convert any Loans into, LIBO Rate Loans shall forthwith be suspended until
the Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

      SECTION 4.3. Increased LIBO Rate Loan Costs, etc. The Borrower agrees to
reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or of converting (or of its obligation to convert) any
Loans into, LIBO Rate Loans (excluding any amounts, whether or not constituting
Taxes, referred to in Section 4.6) arising as a result of any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority that occurs after the date upon which such
Lender became a Lender hereunder. Such Lender shall promptly notify the
Administrative Agent and the Borrower in writing of the occurrence of any such
event, such notice to state, in reasonable detail, the reasons therefor and the
additional amount required fully to compensate such Lender for such increased
cost or reduced amount. Such additional amounts shall be payable by the Borrower
directly to such Lender within five days of its receipt of such notice, and such
notice shall, in the absence of manifest error, be conclusive and binding on the
Borrower.

      SECTION 4.4. Funding Losses. In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the


                                       56
<PAGE>   64
principal amount of any Loan as, or to convert any portion of the principal
amount of any Loan into, a LIBO Rate Loan, but excluding any loss of margin
after the date of any such conversion, repayment, prepayment or failure to
borrow, continue or convert) as a result of (i) any conversion or repayment or
prepayment of the principal amount of any LIBO Rate Loans on a date other than
the scheduled last day of the Interest Period applicable thereto, whether
pursuant to Section 3.1 or otherwise, (ii) any Loans not being borrowed as LIBO
Rate Loans in accordance with the Borrowing Request therefor, or (iii) any Loans
not being continued as, or converted into, LIBO Rate Loans in accordance with
the Continuation/ Conversion Notice therefor, then, upon the written notice of
such Lender to the Borrower (with a copy to the Administrative Agent), the
Borrower shall, within five days of its receipt thereof, pay directly to such
Lender such amount as will (in the reasonable determination of such Lender)
reimburse such Lender for such loss or expense. Such written notice (which shall
include calculations in reasonable detail) shall, in the absence of manifest
error, be conclusive and binding on the Borrower.

      SECTION 4.5. Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority, in each case occurring after the applicable
Lender becomes a Lender hereunder, affects or would affect the amount of capital
required or expected to be maintained by any Lender or any Person controlling
such Lender, and such Lender determines (in its sole and absolute discretion)
that the rate of return on its or such controlling Person's capital as a
consequence of its Commitments, participation in Letters of Credit or the Loans
made by such Lender is reduced to a level below that which such Lender or such
controlling Person could have achieved but for the occurrence of any such
circumstance, then, in any such case upon notice from time to time by such
Lender to the Borrower, the Borrower shall immediately pay directly to such
Lender additional amounts sufficient to compensate such Lender or such
controlling Person for such reduction in rate of return. A statement of such
Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrower. In determining such amount, such Lender
may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable; provided, that such Lender may not
impose materially greater costs on the Borrower than on other similarly situated
borrowers by virtue of any such averaging or attribution method.

      SECTION 4.6. Taxes. (a) All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder (including
Reimbursement Obligations, fees and expenses) shall be made free and clear of
and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of
any nature whatsoever imposed by any taxing authority, but excluding (i) any
income, excise, stamp or franchise taxes and other similar taxes, fees, duties,
withholdings or other charges imposed on either of the Agents as a result of a
present or former connection between the applicable lending office (or office
through which it performs any of its actions as Agent) of such Agent, and any
income, excise, stamp or franchise taxes and other similar taxes, fees,


                                       57
<PAGE>   65
duties, withholdings or other charges imposed on any Lender as a result of a
present or former connection between the applicable lending office of such
Lender, in each case, and the jurisdiction of the governmental authority
imposing such tax or any political subdivision or taxing authority thereof or
therein (other than any such connection arising solely from such Agent or such
Lender having executed, delivered or performed its obligations or received a
payment under, or taken any action to enforce, this Agreement and any Note) or
(ii) any income, excise, stamp or franchise taxes and other similar taxes, fees,
duties, withholdings or other charges to the extent that they are in effect and
would apply as of the date any Person becomes a Lender or Assignee Lender, or as
of the date that any Lender changes its applicable lending office, to the extent
such taxes become applicable as a result of such change (other than a change in
an applicable lending office made pursuant to Section 4.10 below) (such
non-excluded items being called "Taxes"). In the event that any withholding or
deduction from any payment to be made by the Borrower hereunder is required in
respect of any Taxes pursuant to any applicable law, rule or regulation, then
the Borrower will (i) pay directly to the relevant taxing authority the full
amount required to be so withheld or deducted, (ii) promptly forward to the
Administrative Agent an official receipt or other documentation available to the
Borrower reasonably satisfactory to the Administrative Agent evidencing such
payment to such authority, and (iii) pay to the Administrative Agent for the
account of the Lenders such additional amount or amounts as is necessary to
ensure that the net amount actually received by each Lender will equal the full
amount such Lender would have received had no such withholding or deduction been
required, provided, however, that the Borrower shall not be required to pay any
such additional amounts in respect of amounts payable to any Lender that is not
organized under the laws of the United States or a state thereof if such Lender
fails to comply with the requirements of clause (b) of Section 4.6.

      Moreover, if any Taxes are directly asserted against either of the Agents
or any Lender with respect to any payment received by such Agents or such Lender
hereunder, such Agents or such Lender may pay such Taxes and the Borrower will
promptly pay to such Person such additional amount (including any penalties,
interest or expenses) as is necessary in order that the net amount received by
such Person (including any Taxes on such additional amount) shall equal the
amount of such Taxes paid by such Person; provided, however, that the Borrower
shall not be obligated to make payment to the Lenders or the Agents (as the case
may be) pursuant to this sentence in respect of penalties or interest
attributable to any Taxes, if written demand therefor has not been made by such
Lenders or the Agents within 60 days from the date on which such Lenders or the
Agents knew of the imposition of Taxes by the relevant taxing authority or for
any additional imposition which may arise from the failure of the Lenders or the
Agents to apply payments in accordance with the tax law after the Borrower has
made the payments required hereunder; provided, further, that the Borrower shall
not be required to pay any such additional amounts in respect of any amounts
payable to any Lender or the Agent (as the case may be) that is not organized
under the laws of the United States or a state thereof to the extent the related
Tax is imposed as a result of such Lender failing to comply with the
requirements of clause (b) of Section 4.6. After the Lenders or the Agents (as
the case may be) learn of the imposition of Taxes, such Lenders and the Agents
will act in good faith to notify the Borrower of its obligations hereunder as
soon as reasonably possible.


                                       58
<PAGE>   66
      If the Borrower fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent, for the account of the
respective Lenders, the required receipts or other required documentary
evidence, the Borrower shall indemnify the Lenders for any incremental Taxes,
interest or penalties that may become payable by any Lender as a result of any
such failure.

      (b) Each Non-U.S. Lender shall, (i) on or prior to the date of the
execution and delivery of this Agreement, in the case of each Lender listed on
the signature pages hereof, or, in the case of an Assignee Lender, on or prior
to the date it becomes a Lender, execute and deliver to the Borrower and the
Administrative Agent, two or more (as the Borrower or the Agents may reasonably
request) United States Internal Revenue Service Forms 4224 or Forms 1001 or,
solely if such Lender is claiming exemption from United States withholding tax
under Section 871(h) or 881(c) of the Code with respect to payments of
"portfolio interest", United States Internal Revenue Service Forms W-8 and a
certificate signed by a duly authorized officer of such Lender representing that
such Lender is not a "bank" within the meaning of Section 881(c)(3)(A) of the
Code, or such other forms or documents (or successor forms or documents),
appropriately completed, establishing that payments to such Lender are exempt
from withholding or deduction of Taxes; and (ii) deliver to the Borrower and the
Administrative Agent two further copies of any such form or documents on or
before the date that any such form or document expires or becomes obsolete and
after the occurrence of any event requiring a change in the most recent such
form or document previously delivered by it to the Borrower.

      (c) If the Borrower determines in good faith that a reasonable basis
exists for contesting the imposition of a Tax with respect to a Lender or either
of the Agents, the relevant Lender or Agent, as the case may be, shall cooperate
with the Borrower in challenging such Tax at the Borrower's expense if requested
by the Borrower; provided, however, that nothing in this Section 4.6 shall
require any Lender to submit to the Borrower or any other Person any tax returns
or any part thereof, or to prepare or file any tax returns other than as such
Lender in its sole discretion shall determine.

      (d) If a Lender or an Agent shall receive a refund (including any offset
or credits from a taxing authority (as a result of any error in the imposition
of Taxes by such taxing authority)) of any Taxes paid by the Borrower pursuant
to subsection 4.6(a) above, such Lender or the Agent (as the case may be) shall
promptly pay the Borrower the amount so received, with interest from the taxing
authority with respect to such refund.

      (e) Each Lender and each Agent agrees, to the extent reasonable and
without material cost to it, to cooperate with the Borrower to minimize any
amounts payable by the Borrower under this Section 4.6.

      SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly
provided, all payments by or on behalf of the Borrower pursuant to this
Agreement, the Notes or any other Loan Document shall be made by the Borrower to
the Administrative Agent for the pro rata account of the Lenders, Agents or
Arranger, as applicable, entitled to receive such payment. All


                                       59
<PAGE>   67
such payments required to be made to the Administrative Agent shall be made,
without setoff, deduction or counterclaim, not later than 1:00 p.m., New York
time, on the date due, in same day or immediately available funds, to such
account as the Administrative Agent shall specify from time to time by notice to
the Borrower. Funds received after that time shall be deemed to have been
received by the Administrative Agent on the next succeeding Business Day. The
Administrative Agent shall promptly remit in same day funds to each Lender,
Agent or Arranger, as the case may be, its share, if any, of such payments
received by the Administrative Agent for the account of such Lender, Agent or
Arranger, as the case may be. All interest and fees shall be computed on the
basis of the actual number of days (including the first day but excluding the
last day) occurring during the period for which such interest or fee is payable
over a year comprised of 360 days (or, in the case of interest on a Base Rate
Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made
shall otherwise be due on a day which is not a Business Day, such payment shall
(except as otherwise required by clause (i) of the definition of the term
"Interest Period") be made on the next succeeding Business Day and such
extension of time shall be included in computing interest and fees, if any, in
connection with such payment.

      SECTION 4.8. Sharing of Payments. If any Lender shall obtain any payment
or other recovery (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Loan or Reimbursement Obligations (other than
pursuant to the terms of Sections 4.3, 4.4 and 4.5) in excess of its pro rata
share of payments then or therewith obtained by all Lenders entitled thereto,
such Lender shall purchase from the other Lenders such participation in the
Credit Extensions made by them as shall be necessary to cause such purchasing
Lender to share the excess payment or other recovery ratably with each of them;
provided, however, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing Lender, the purchase shall
be rescinded and each Lender which has sold a participation to the purchasing
Lender shall repay to the purchasing Lender the purchase price to the ratable
extent of such recovery together with an amount equal to such selling Lender's
ratable share (according to the proportion of (i) the amount of such selling
Lender's required repayment to the purchasing Lender in respect of such
recovery, to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by law, exercise all its rights of payment
(including pursuant to Section 4.9) with respect to such participation as fully
as if such Lender were the direct creditor of the Borrower in the amount of such
participation. If under any applicable bankruptcy, insolvency or other similar
law, any Lender receives a secured claim in lieu of a setoff to which this
Section applies, such Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Lenders entitled under this Section to share in the benefits of any
recovery on such secured claim.

      SECTION 4.9. Setoff. Each Lender shall, upon the occurrence of any Event
of Default described in clauses (b) through (d) of Section 8.1.9 with respect to
any Obligor (other than immaterial Subsidiaries) or, with the consent of the
Required Lenders, upon the occurrence of any other Event of Default, to the
fullest extent permitted by law, have the right to appropriate


                                       60
<PAGE>   68
and apply to the payment of the Obligations then due to it, and (as security for
such Obligations) the Borrower hereby grants to each Lender a continuing
security interest in, any and all balances, credits, deposits, accounts or
moneys of the Borrower then or thereafter maintained with or otherwise held by
such Lender; provided, however, that any such appropriation and application
shall be subject to the provisions of Section 4.8. Each Lender agrees promptly
to notify the Borrower and the Administrative Agent after any such setoff and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such setoff and application. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff under applicable law or otherwise)
which such Lender may have.

      SECTION 4.10. Mitigation. Each Lender agrees that if it makes any demand
for payment under Sections 4.3, 4.4, 4.5, or 4.6, or if any adoption or change
of the type described in Section 4.1 shall occur with respect to it, it will use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, as
determined in its sole discretion) to designate a different lending office if
the making of such a designation would reduce or obviate the need for the
Borrower to make payments under Section 4.3, 4.4, 4.5, or 4.6, or would
eliminate or reduce the effect of any adoption or change described in Section
4.1.

      SECTION 4.11. Replacement of Lenders. Each Lender hereby severally agrees
as set forth in this Section. If any Lender (a "Subject Lender") makes demand
upon the Borrower for (or if the Borrower is otherwise required to pay) amounts
pursuant to Section 4.3, 4.5 or 4.6, or gives notice pursuant to Section 4.1
requiring a conversion of such Subject Lender's LIBO Rate Loans to Base Rate
Loans or suspending such Lender's obligation to make Loans as, or to convert
Loans into, LIBO Rate Loans, the Borrower may, within 90 days of receipt by the
Borrower of such demand or notice (or the occurrence of such other event causing
the Borrower to be required to pay such compensation), as the case may be, give
notice (a "Replacement Notice") in writing to the Agents and such Subject Lender
of its intention to replace such Subject Lender with a financial institution (a
"Replacement Lender") designated in such Replacement Notice. If the Agents
shall, in the exercise of their reasonable discretion and within 30 days of
their receipt of such Replacement Notice, notify the Borrower and such Subject
Lender in writing that the designated financial institution is satisfactory to
the Agents (such consent not being required where the Replacement Lender is
already a Lender), then such Subject Lender shall, subject to the payment of any
amounts due pursuant to Section 4.4, assign, in accordance with Section 10.11.1,
all of its Commitments, Loans, Notes and other rights and obligations under this
Agreement and all other Loan Documents (including, without limitation,
Reimbursement Obligations) to such designated financial institution; provided,
however, that (i) such assignment shall be without recourse, representation or
warranty and shall be on terms and conditions reasonably satisfactory to such
Subject Lender and such designated financial institution and (ii) the purchase
price paid by such designated financial institution shall be in the amount of
such Subject Lender's Loans and its Percentage of outstanding Reimbursement
Obligations, together with all accrued and unpaid interest and fees in respect
thereof, plus all other amounts (including the amounts demanded and unreimbursed
under Sections 4.3, 4.5 and


                                       61
<PAGE>   69
4.6), owing to such Subject Lender hereunder. Upon the effective date of an
assignment described above, the Borrower shall issue a replacement Note or
Notes, as the case may be, to such designated financial institution or
Replacement Lender, as applicable, and such institution shall become a "Lender"
for all purposes under this Agreement and the other Loan Documents.

standing to the extent required under the laws of the jurisdiction of its
incorporation, is duly qualified to do business and is in good standing as a

      SECTION 6.2. Due Authorization, Non-Contravention, etc. The execution,
delivery and performance by the Borrower of this Agreement, the Notes and each
other Loan Document executed or to be executed by it, and the execution,
delivery and performance by each other Obligor of each Loan Document executed or
to be executed by it and the Borrower's and, where applicable, each such other
Obligor's participation in the consummation of the Transaction, are within the
Borrower's and each such Obligor's corporate powers, have been duly authorized
by all necessary corporate action, and do not (i) contravene the Borrower's or
any such Obligor's Charter Documents, (ii) contravene any contractual
restriction, law or governmental regulation or court decree or order binding on
or affecting the Borrower or any such Obligor, where such contravention,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect, or (iii) result in, or require the creation or
imposition of, any Lien on any of the Borrower's or any other Obligor's
properties, except pursuant to the terms of a Loan Document.

      SECTION 6.3. Government Approval, Regulation, etc. No authorization or

delivery thereof, constitute, the legal, valid and binding obligations of the
Borrower enforceable in accordance with their respective terms; and each Loan
Document executed pursuant hereto by each other Obligor will, on the due
execution and delivery thereof by such Obligor, be the legal, valid and binding
obligation of such Obligor enforceable in accordance with its terms, in each
case with respect to this Section 6.4 subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

      SECTION 6.5. Financial Information. The Borrower has delivered to the
Agents and each Lender copies of each of (i) the Base Financial Statements, and
(ii) a Pro Forma Balance Sheet. Each of the financial statements described above

consistent with the basis used to prepare the financial statements referred to
in clause (i), and (in the case of clause (i)) present fairly the consolidated
financial condition of the corporations covered thereby as at the date thereof
and the results of their operations for the periods then ended and (in the case
of clause (ii)) include appropriate pro forma adjustments to give pro forma
effect to the Transaction.

      SECTION 6.6. No Material Adverse Change. Since June 30, 1996, there has
been no material adverse change in the financial condition, operations, assets,
business, properties or prospects of the Borrower and its Restricted
Subsidiaries, taken as a whole.

      SECTION 6.7. Litigation, Labor Controversies, etc. There is no pending or,
to the knowledge of the Borrower, threatened litigation, action, proceeding,
labor controversy, arbitration or governmental investigation affecting any
Obligor, or any of their respective properties, businesses, assets or revenues,
which could reasonably be expected to result in a Material Adverse Effect except
as disclosed in Item 6.7 ("Litigation") of the Disclosure Schedule. No material
adverse development has occurred in any litigation, action, labor controversy,
arbitration or governmental investigation or other proceeding disclosed in Item
6.7 ("Litigation") of the Disclosure Schedule.

      SECTION 6.8. Subsidiaries. The Borrower has only those Subsidiaries (i)
which are identified in Item 6.8 ("Existing Subsidiaries") of the Disclosure
Schedule, or (ii) which are permitted to have been acquired in accordance with
Section 7.2.5 or 7.2.8.

      SECTION 6.9. Ownership of Properties. Except to the extent that the
failure to do so could not reasonably be expected to have a Material Adverse
Effect, the Borrower and each


                                       68
<PAGE>   76
of its Subsidiaries owns good title to, or leasehold interests in, all of its
properties and assets (other than insignificant properties and assets), real and
personal, tangible and intangible, of any nature whatsoever (including patents,
trademarks, trade names, service marks and copyrights), free and clear of all
Liens or material claims (including material infringement claims with respect to
patents, trademarks, copyrights and the like), except as permitted pursuant to
Section 7.2.3.

      SECTION 6.10. Taxes. Each of Holdings, the Borrower and each of the
Borrower's Restricted Subsidiaries has filed all Federal, State and other
material tax returns required by law to have been filed by it and has paid all
taxes and governmental charges thereby shown to be owing, except any such taxes
or charges which are being contested in good faith by appropriate proceedings
and for which adequate reserves in accordance with GAAP shall have been set
aside on its books.

      SECTION 6.11. Pension and Welfare Plans. During the
twelve-consecutive-month period prior to the date of the execution and delivery
of this Agreement, no steps have been taken to terminate any Pension Plan, and
no contribution failure has occurred with respect to any Pension Plan sufficient
to give rise to a Lien under section 302(f) of ERISA, which, in either case, is
reasonably expected to lead to a liability to such Pension Plan in excess of
$10,000,000. No condition exists or event or transaction has occurred with
respect to any Pension Plan which could reasonably be expected to result in the
incurrence by the Borrower or any member of the Controlled Group of any material
liability, fine or penalty other than such condition, event or transaction which
would not reasonably be expected to have a Material Adverse Effect. Except as
disclosed in Item 6.11 ("Employee Benefit Plans") of the Disclosure Schedule or
otherwise approved by the Agents (such approval not to be unreasonably withheld
or delayed), since the date of the last financial statement the Borrower has not
increased any contingent liability with respect to any post-retirement benefit
under a Welfare Plan, other than liability for continuation coverage described
in Part 6 of Subtitle B of Title I of ERISA, except as would not have Material
Adverse Effect.

      SECTION 6.12. Environmental Matters. Except as set forth in Item 6.12
("Environmental Matters") of the Disclosure Schedule or as, individually or in
the aggregate, could not reasonably be expected to have a Material Adverse
Effect:

      owned or leased by the Borrower or any of its Subsidiaries are, and
      continue to be, owned or leased by the Borrower and its Subsidiaries in
      compliance with all Environmental Laws;

            (b) there have been no past, and there are no pending or threatened
      (i) written claims, complaints, notices or requests for information
      received by the Borrower or any of its Subsidiaries with respect to any
      alleged violation of any Environmental Law, or (ii) written complaints,
      notices or inquiries to the Borrower or any of its Subsidiaries regarding
      potential liability under any Environmental Law;


                                       69
<PAGE>   77
            (c) to the best knowledge of the Borrower, there have been no
      Releases of Hazardous Materials at, on or under any property now or
      previously owned or leased by the Borrower or any of its Subsidiaries;

      desirable for their businesses;

            (e) no property now or, to the best knowledge of the Borrower,
      previously owned or leased by the Borrower or any of its Subsidiaries is
      listed or, to the knowledge of the Borrower or any of its Subsidiaries,
      proposed for listing (with respect to owned property only) on the National
      Priorities List pursuant to CERCLA, on the CERCLIS or on any similar state
      list of sites requiring investigation or clean-up;

            (f) to the best knowledge of the Borrower, there are no underground
      storage tanks, active or abandoned, including petroleum storage tanks, on
      or under any property now or previously owned or leased by the Borrower or
      any of its Subsidiaries;

            (g) to the best knowledge of the Borrower, the Borrower and its
      Subsidiaries have not directly transported or directly arranged for the
      transportation of any Hazardous Material to any location which is listed
      or to the knowledge of the Borrower or any of its Subsidiaries, proposed
      for listing on the National Priorities List pursuant to CERCLA, on the
      CERCLIS or on any similar state list;

            (h) to the best knowledge of the Borrower, there are no
      polychlorinated biphenyls or friable asbestos present in a manner or
      condition at any property now or previously owned or leased by the
      Borrower or any Subsidiary of the Borrower; and

            (i) to the best knowledge of the Borrower, no conditions exist at,
      on or under any property now or previously owned or leased by the Borrower
      or any of its Subsidiaries which, with the passage of time, or the giving
      of notice or both, would give rise to liability to the Borrower or any of
      its Subsidiaries under any Environmental Law.

      SECTION 6.13. Regulations G, U and X. Neither the Borrower nor Holdings is
engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock, and no proceeds of any Credit Extension will be used in
violation of F.R.S. Board Regulation G, U or X. Terms for which meanings are
provided in F.R.S. Board Regulation G, U or X or any regulations substituted
therefor, as from time to time in effect, are used in this Section with such
meanings.

      SECTION 6.14. Accuracy of Information. All material factual information
concerning the financial condition, operations or prospects of Holdings, the
Borrower, and the Borrower's Restricted Subsidiaries heretofore or
contemporaneously furnished by or on behalf of the Borrower in writing to the
Agents, the Arranger, the Issuer or any Lender for purposes of or in


                                       70
<PAGE>   78
connection with this Agreement or any transaction contemplated hereby or with
respect to the Transaction is, and all other such factual information hereafter
furnished by or on behalf of the Borrower, or any of its Restricted Subsidiaries
to the Agents, the Arranger, the Issuer or any Lender will be, taken as a whole,
true and accurate in every material respect on the date as of which such
information is dated or certified and such information is not, or shall not be,
taken as a whole, as the case may be, incomplete by omitting to state any
material fact necessary to make such information not misleading.

      Any term or provision of this Section to the contrary notwithstanding,
insofar as any of the factual information described above includes assumptions,
estimates, projections or opinions, no representation or warranty is made herein
with respect thereto; provided, however, that to the extent any such
assumptions, estimates, projections or opinions are based on factual matters,
the Borrower has reviewed such factual matters and nothing has come to its
attention in the context of such review which would lead it to believe that such
factual matters were not or are not true and correct in all material respects or
that such factual matters omit to state any material fact necessary to make such
assumptions, estimates, projections or opinions not misleading in any material
respect.

      SECTION 6.15. Solvency. The Transaction (including, among other things,
the incurrence of the initial Credit Extension hereunder, the incurrence by the
Borrower of the Indebtedness represented by the Notes and the Subordinated
Notes, the execution and delivery by the Subsidiary Guarantors, if any, of a
Subsidiary Guaranty, the consummation of the Discount Debenture Issuance and the
application of the proceeds of the Credit Extensions), will not involve or
result in any fraudulent transfer or fraudulent conveyance under the provisions
of Section 548 of the Bankruptcy Code (11 U.S.C. Section 101 et seq., as from
time to time hereafter amended, and any successor or similar statute) or any
applicable state law respecting fraudulent transfers or fraudulent conveyances.
On the Closing Date, after giving effect to the Transaction, the Borrower is
Solvent.

cause each of its Subsidiaries to, comply in all material respects with all
applicable laws, rules, regulations and orders, such compliance to include
(without limitation) (i) except as permitted under Section 7.2.8, the
maintenance and preservation of its corporate existence and qualification as a
foreign corporation, except where the failure to so qualify could not reasonably
be expected to have a Material Adverse Effect, and (ii) the payment, before the
same become delinquent, of all material taxes, assessments and governmental
charges imposed upon it or upon its property except to the extent being
contested in good faith by appropriate proceedings and for which adequate
reserves in accordance with GAAP shall have been set aside on its books.

      SECTION 7.1.3. Maintenance of Properties. Except to the extent that the
failure to do so could not reasonably be expected to have a Material Adverse
Effect, the Borrower will, and will cause each of its Subsidiaries to, maintain,
preserve, protect and keep its properties (other than insignificant properties)
in good repair, working order and condition (ordinary wear


                                       73
<PAGE>   81
and tear excepted), and make necessary and proper repairs, renewals and

properly conducted at all times unless the Borrower determines in good faith
that the continued maintenance of any of its properties is no longer
economically desirable.

      SECTION 7.1.4. Insurance. The Borrower will, and will cause each of its
Restricted Subsidiaries to, maintain or cause to be maintained with responsible
insurance companies insurance with respect to its properties and business

reflect in all material respects all of its business affairs and transactions
and permit the Agents, the Issuer and each Lender or any of their respective
representatives, at reasonable times and intervals, and upon reasonable notice,
but, unless an Event of Default shall have occurred and be continuing, not more
frequently than once in each Fiscal Year, to visit its corporate offices, to
discuss its financial matters with its officers and, only in the presence of a
representative of the Borrower (whose attendance at such discussion cannot be
unreasonably refused), its independent public accountants (and the Borrower
hereby authorizes such independent public accountants to discuss the Borrower's
financial matters with the Issuer and each Lender or its representatives, so
long as a representative of the Borrower is present) and to examine any of its
books or other financial records. The cost and expense of each such visit shall
be borne by the applicable Agent or Lender.

      environmental matters in effect and remain in compliance therewith, and
      handle all Hazardous Materials in compliance with all applicable

      the terms of this clause could not reasonably be expected to have a
      Material Adverse Effect;

            (b) promptly notify the Agents and provide copies of all written
      claims, complaints, notices or inquiries relating to the condition of its
      facilities and properties or compliance with Environmental Laws which
      would have, or would reasonably be expected to have, a Material Adverse
      Effect, and promptly cure and have dismissed with prejudice any material
      actions and proceedings relating to compliance with Environmental Laws,
      except to the extent being diligently contested in good faith by


                                       74
<PAGE>   82
      appropriate proceedings and for which adequate reserves in accordance with
      GAAP have been set aside on its books; and

            (c) provide such information and certifications which the Agents may
      reasonably request from time to time to evidence compliance with this
      Section 7.1.6.

      SECTION 7.1.7. Future Subsidiaries; Material Subsidiaries. The Borrower
hereby covenants and agrees as follows:

            (a) Upon any Person (other than the Trademark Subsidiary and the IPO
      Subsidiary) becoming, after the Closing Date, a Material Subsidiary of the
      Borrower that is a U.S. Subsidiary, or (in the case of clause (a)(ii)
      below only) upon the Borrower or any Material Subsidiary of the Borrower
      that is a U.S. Subsidiary (other than the Trademark Subsidiary and the IPO
      Subsidiary) acquiring additional Capital Stock of any existing Material
      Subsidiary (other than an Unrestricted Subsidiary, the Trademark
      Subsidiary and the IPO Subsidiary), the Borrower shall notify the Agents
      of such acquisition, and

                  (i) the Borrower shall promptly cause such Material Subsidiary
            to execute and deliver to the Administrative Agent, with
            counterparts for each Lender, a Subsidiary Security Agreement (or a
            supplement thereto) (and, if such Material Subsidiary owns any real
            property, to the extent required by clause (b) of Section 7.1.8, a
            Mortgage), together with Uniform Commercial Code financing
            statements (form UCC-1) executed and delivered by the Material
            Subsidiary naming the Material Subsidiary as the debtor and the
            Administrative Agent as the secured party, or other similar
            instruments or documents, in appropriate form for filing under the
            Uniform Commercial Code and any other applicable recording statutes,
            in the case of real property, of all jurisdictions as may be
            necessary or, in the opinion of the Administrative Agent, desirable
            to perfect the security interest of the Administrative Agent
            pursuant to the Subsidiary Security Agreement or a Mortgage, as the
            case may be (other than the perfection of security interests in
            motor vehicles); and

                  (ii) the Borrower shall promptly deliver, or cause to be
            delivered, to the Administrative Agent under a Pledge Agreement (or
            a supplement thereto) certificates (if any) representing all of the
            issued and outstanding shares of Capital Stock of such Subsidiary
            (other than an Unrestricted Subsidiary, the Trademark Subsidiary and
            the IPO Subsidiary) owned by the Borrower or any Material Subsidiary
            of the Borrower that is a U.S. Subsidiary, as the case may be, along
            with undated stock powers for such certificates, executed in blank,
            or, if any securities subject thereto are uncertificated securities
            or are held through a financial intermediary, confirmation and
            evidence satisfactory to the Agents that appropriate book entries
            have been made in the relevant books or records of a financial
            intermediary or the issuer of such securities, as the case may be,
            or other


                                       75
<PAGE>   83
            appropriate steps shall have been taken under applicable law
            resulting in the perfection of the security interest granted in
            favor of the Administrative Agent pursuant to the terms of a Pledge
            Agreement;

      together, in each case, with such opinions, in form and substance and from
      counsel satisfactory to the Agents, as the Agents may reasonably require;
      provided, however, that notwithstanding the foregoing, no Non-U.S.
      Subsidiary shall be required to execute and deliver a Mortgage or a
      Subsidiary Security Agreement (or a supplement thereto), nor will the
      Borrower or any Subsidiary of the Borrower be required to deliver in
      pledge pursuant to a Pledge Agreement in excess of 65% of the total
      combined voting power of all classes of Capital Stock of a Non-U.S.
      Subsidiary entitled to vote.

            (b) Upon any Person (other than the Trademark Subsidiary and the IPO
      Subsidiary) becoming, after the Closing Date, a Material Subsidiary of the
      Borrower that is a U.S. Subsidiary, the Borrower shall notify the Agents
      of such event, and the Borrower shall promptly cause such Material
      Subsidiary to execute and deliver to the Administrative Agent, with
      counterparts for each Lender, a Subsidiary Guaranty together with such
      opinions, in form and substance and from counsel satisfactory to the
      Agents, as the Agents may reasonably require.

      SECTION 7.1.8. Future Leased Property and Future Acquisitions of Real
Property; Future Acquisition of Other Property.

            (a) Prior to entering into any new lease of real property or
      renewing any existing lease of real property following the Closing Date,
      the Borrower shall, and shall cause each of its U.S. Subsidiaries (other
      than the Trademark Subsidiary and the IPO Subsidiary) that is a Restricted
      Subsidiary to, use its (and their) best efforts (which shall not require
      the expenditure of cash or the making of any material concessions under
      the relevant lease) to deliver to the Administrative Agent a Waiver
      executed by the lessor of any real property that is to be leased by the
      Borrower or such U.S. Subsidiary for a term in excess of one year in any
      state which by statute grants such lessor a "landlord's" (or similar) Lien
      which is superior to the Administrative Agent's, to the extent the value
      of any personal property of the Borrower or its U.S. Subsidiaries to be
      held at such leased property exceeds (or it is anticipated that the value
      of such personal property will, at any point in time during the term of
      such leasehold term, exceed) $10,000,000.

      certifying to the accuracy of clause (A) above and certifying that no
      Default shall have occurred and be continuing on the date such Restricted
      Payment is made, nor would a Default result from the making of such
      Restricted Payment;

            (e) notwithstanding the provisions of clauses (a) and (b) above, the
      Borrower and its Subsidiaries shall be permitted to make the Restricted
      Payments included in the Transaction; and

      Borrower may pay a dividend to Holdings consisting solely of a transfer of
      all or a portion of the Intercompany Loan.

      SECTION 7.2.7. Capital Expenditures, etc. With respect to Capital

            (a) The Borrower will not, and will not permit any of its Restricted
      Subsidiaries to, make or commit to make Capital Expenditures in any Fiscal
      Year, except Capital Expenditures of the Borrower and its Restricted
      Subsidiaries (other than the Trademark Subsidiary and the IPO Subsidiary)
      which do not aggregate in excess of (x) in the case of Fiscal Years ending
      on or prior to June 30, 2000, $20,000,000 in such Fiscal Year or (y) in
      the case of any Fiscal Year thereafter, $25,000,000 in such Fiscal Year;
      provided, however, that, to the extent the amount of Capital Expenditures
      permitted to be made in any Fiscal Year pursuant to this Section exceeds
      the aggregate amount of Capital Expenditures actually made during such
      Fiscal Year, such excess amount (up to an aggregate of 50% of the amount
      of Capital Expenditures permitted for such Fiscal Year, without giving
      effect to this proviso) may be carried forward to (but only to) the next
      succeeding Fiscal Year (any such amount to be certified by the Borrower to
      the Agents in the Compliance Certificate delivered for the last Fiscal
      Quarter of such Fiscal Year, and any such amount carried forward to a
      succeeding Fiscal Year shall be deemed to be used prior to the Borrower
      and its Subsidiaries using the amount of Capital Expenditures permitted by
      this Section in such succeeding Fiscal Year, without giving effect to such
      carry-forward).

            (b) The parties acknowledge and agree that the permitted Capital
      Expenditure level set forth in clause (a) above shall be exclusive of (i)
      the amount of Capital Expenditures actually made with cash capital
      contributions made, directly or indirectly, to the Borrower or any of its
      Restricted Subsidiaries by Holdings, the proceeds of equity issuances made
      by the Borrower or any of its Restricted Subsidiaries, directly or
      indirectly, to Holdings, and repayments by Holdings of the Intercompany
      Loan, in each case after the Closing Date and specifically identified in a
      certificate delivered by an Authorized Officer of the Borrower to the
      Agents on or about the time such capital


                                       87
<PAGE>   95
      contribution or equity issuance is made and (ii) that portion of any
      acquisition that is permitted under Section 7.2.5 (other than pursuant to

not permit any of its Restricted Subsidiaries to, liquidate or dissolve,
consolidate with, or merge into or with, any other corporation, or purchase or
otherwise acquire all or substantially all of the assets of any Person (or of
any division thereof) except

            (a) any such Restricted Subsidiary may liquidate or dissolve
      voluntarily into, and may merge with and into, the Borrower (so long as
      the Borrower is the surviving corporation of such combination or merger)
      or any other Subsidiary, and the assets or stock of any Restricted
      Subsidiary may be purchased or otherwise acquired by the Borrower or any
      other Restricted Subsidiary; provided, that notwithstanding the above, a
      Restricted Subsidiary may only liquidate or dissolve into, or merge with
      and into, another Restricted Subsidiary of the Borrower if, after giving
      effect to such combination or merger, the Borrower continues to own
      (directly or indirectly), and the Administrative Agent continues to have
      pledged to it pursuant to a Pledge Agreement, a percentage of the issued
      and outstanding shares of Capital Stock (on a fully diluted basis) of the
      Restricted Subsidiary surviving such combination or merger that is equal
      to or in excess of the percentage of the issued and outstanding shares of
      Capital Stock (on a fully diluted basis) of the Restricted Subsidiary that
      does not survive such combination or merger that was (immediately prior to
      the combination or merger) owned by the Borrower or pledged to the
      Administrative Agent;

            (b) so long as no Default has occurred and is continuing or would
      occur after giving effect thereto, the Borrower or any of its Restricted
      Subsidiaries (other than the Trademark Subsidiary and the IPO Subsidiary)
      may purchase all or substantially all of the assets of any Person (or any
      division thereof) not then a Subsidiary, or acquire such Person by merger,
      if permitted (without duplication) pursuant to Section 7.2.7 or clause
      (f), (j) or (k) of Section 7.2.5;

property acquired after the Closing Date, and the IPO Subsidiary):

<PAGE>   96
            (a) such sale, transfer, lease, contribution or conveyance of such
      assets is (i) in the ordinary course of its business (and does not
      constitute a sale, transfer, lease, contribution or other conveyance of
      all or a substantial part of the Borrower's and its Restricted
      Subsidiaries' assets, taken as a whole) or is of obsolete or worn out
      property, (ii) permitted by Section 7.2.8, or (iii) between the Borrower
      and one of its Subsidiaries or between Subsidiaries of the Borrower;

            (b) such sale, transfer, lease, contribution or conveyance

written consent of the Required Lenders, the Borrower will not, and will not
permit any of its Restricted Subsidiaries to, consent to any amendment,
supplement, amendment and restatement, waiver or other modification of any of
the terms or provisions contained in, or applicable to, the Discount Debentures,
any Subordinated Note (including any agreement or indenture related thereto or
to the Subordinated Debt Issuance) or any Material Document or any schedules,
exhibits or agreements related thereto, in each case which would materially
adversely affect the rights or remedies of the Lenders, or the Borrower's or any
other Obligor's ability to perform hereunder or under any Loan Document or which
would increase the cash consideration payable in respect of the Merger or, in
the case of the Merger Agreement, which would increase the Borrower's or any of
its Restricted Subsidiaries' obligations or liabilities, contingent or otherwise
(other than adjustments to the cash consideration payable in respect of the
Merger made pursuant to the terms of the Merger Agreement).

      other agreement or arrangement which restricts the ability of any such
      Restricted Subsidiary to make any payment, directly or indirectly, to the
      Borrower (other than any limitations or prohibitions existing in any
      Indebtedness permitted under clause (a) of Section 7.2.2 or any Lien
      permitted under clause (a) of Section 7.2.3 or customary limitations and
      prohibitions in any Indebtedness permitted under clause (h) of Section

excess of $10,000,000 if the effect of such default is to accelerate the
maturity of any such Indebtedness or such default shall continue unremedied for
any applicable period of time sufficient to permit the holder or holders of such
Indebtedness, or any trustee or agent for such holders, to cause such
Indebtedness to become due and payable prior to its expressed maturity.

                                       92
<PAGE>   100

      Subsidiary or such other Obligor or shall result in the entry of an order

to be due and payable, require the Borrower to provide cash collateral to be
deposited with the Administrative Agent in an amount equal to the undrawn amount

                                   ARTICLE IX

                                   THE AGENTS

      SECTION 9.1. Actions. Each Lender hereby appoints DLJ as its Syndication
Agent and NationsBank as its Administrative Agent under and for purposes of this
Agreement, the Notes and each other Loan Document. Each Lender authorizes the
Agents to act on behalf of such Lender under this Agreement, the Notes and each
other Loan Document and, in the absence of other written instructions from the
Required Lenders received from time to time by the Agents (with respect to which
each of the Agents agrees that it will comply, except as otherwise provided in
this Section or as otherwise advised by counsel), to exercise such powers
hereunder and thereunder as are specifically delegated to or required of the
Agents by the terms hereof and thereof, together with such powers as may be
reasonably incidental thereto. Each Lender hereby indemnifies (which indemnity
shall survive any termination of this Agreement) the Agents, ratably in
accordance with their respective Term Loans outstanding and Commitments (or, if
no Term Loans or Commitments are at the time outstanding and in effect, then
ratably in accordance with the principal amount of Term Loans held by such
Lender, and their respective Commitments as in effect in each case on the date
of the termination of this Agreement), from and against any and all liabilities,
obligations, losses, damages, claims, costs or expenses of any kind or nature
whatsoever which may at any time be imposed on, incurred by, or asserted
against, either of the Agents in any way relating to or arising out of this
Agreement, the Notes and any other Loan Document, including reasonable
attorneys' fees, and as to which any Agent is not reimbursed by the Borrower or
any other Obligor (and without limiting the obligation of the Borrower or any
other Obligor to do so); provided, however, that no Lender shall be liable for
the payment of any portion of such liabilities, obligations, losses, damages,
claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted solely from such Agent's
gross negligence or willful misconduct. The Agents shall not be required to take
any action hereunder, under the Notes or under any other Loan Document, or


                                       94
<PAGE>   102
to prosecute or defend any suit in respect of this Agreement, the Notes or any
other Loan Document, unless it is indemnified hereunder to its satisfaction. If
any indemnity in favor of either of the Agents shall be or become, in such
Agent's determination, inadequate, the Agent may call for additional
indemnification from the Lenders and cease to do the acts indemnified against
hereunder until such additional indemnity is given.

      SECTION 9.2. Funding Reliance, etc. Unless the Administrative Agent shall
have been notified by telephone, confirmed in writing, by any Lender by 5:00
p.m., New York time, on the day prior to a Borrowing or disbursement with
respect to a Letter of Credit pursuant to Section 2.6.2 that such Lender will
not make available the amount which would constitute its Percentage of such
Borrowing on the date specified therefor, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent and,
in reliance upon such assumption, make available to the Borrower a corresponding
amount. If and to the extent that such Lender shall not have made such amount
available to the Administrative Agent, such Lender severally agrees and the
Borrower agrees to repay the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
the Administrative Agent made such amount available to the Borrower to the date
such amount is repaid to the Administrative Agent, at the interest rate
applicable at the time to Loans comprising such Borrowing.

      SECTION 9.3. Exculpation. None of the Agents or the Arranger nor any of
their respective directors, officers, employees or agents shall be liable to any
Lender for any action taken or omitted to be taken by it under this Agreement or
any other Loan Document, or in connection herewith or therewith, except for its
own willful misconduct or gross negligence, nor responsible for any recitals or
warranties herein or therein, nor for the effectiveness, enforceability,
validity or due execution of this Agreement or any other Loan Document, nor for
the creation, perfection or priority of any Liens purported to be created by any
of the Loan Documents, or the validity, genuineness, enforceability, existence,
value or sufficiency of any collateral security, nor to make any inquiry
respecting the performance by the Borrower of its obligations hereunder or under
any other Loan Document. Any such inquiry which may be made by any Agent or the
Issuer shall not obligate it to make any further inquiry or to take any action.
The Agents and the Issuer shall be entitled to rely upon advice of counsel
concerning legal matters and upon any notice, consent, certificate, statement or
writing which the Agents or the Issuer, as applicable, believe to be genuine and
to have been presented by a proper Person.

      SECTION 9.4. Successor. The Syndication Agent may resign as such upon one
Business Day's notice to the Borrower and the Administrative Agent. The
Administrative Agent may resign as such at any time upon at least 30 days' prior
notice to the Borrower and all Lenders. If the Administrative Agent at any time
shall resign, the Required Lenders may, with the prior consent of the Borrower
(which consent shall not be unreasonably withheld), appoint another Lender as a
successor Administrative Agent which shall thereupon become the Administrative
Agent hereunder. If no successor Administrative Agent shall have been so
appointed by the Required Lenders, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent's giving notice of
resignation, then the retiring


                                       95
<PAGE>   103
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the United States or a United States
branch or agency of a commercial banking institution, and having a combined
capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall be entitled to receive from the
retiring Administrative Agent such documents of transfer and assignment as such
successor Administrative Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges and duties of
the retiring Administrative Agent, and the retiring Administrative Agent shall
be discharged from its duties and obligations under this Agreement. After any
retiring Administrative Agent's resignation hereunder as the Administrative
Agent, the provisions of (i) this Article IX shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was the Administrative
Agent under this Agreement, and (ii) Section 10.3 and Section 10.4 shall
continue to inure to its benefit.

      SECTION 9.5. Credit Extensions by each Agent. Each Agent and the Issuer
shall have the same rights and powers with respect to (x) (i) in the case of the
Agents, the Credit Extensions made by it or any of its Affiliates and (ii) in
the case of the Issuer, the Loans made by it or any of its Affiliates, and (y)
the Notes held by it or any of its Affiliates as any other Lender and may
exercise the same as if it were not an Agent or the Issuer. Each Agent, the
Issuer and each and each of their respective Affiliates may accept deposits
from, lend money to, and generally engage in any kind of business with the
Borrower or any Subsidiary or Affiliate of the Borrower as if such Agent or
Issuer were not an Agent or Issuer hereunder.

      SECTION 9.6. Credit Decisions. Each Lender acknowledges that it has,
independently of each Agent, the Documentation Agent, the Arranger, the Issuer
and each other Lender, and based on such Lender's review of the financial
information of the Borrower, this Agreement, the other Loan Documents (the terms
and provisions of which being satisfactory to such Lender) and such other
documents, information and investigations as such Lender has deemed appropriate,
made its own credit decision to extend its Commitments. Each Lender also
acknowledges that it will, independently of each Agent, the Documentation Agent,
the Arranger, the Issuer and each other Lender, and based on such other
documents, information and investigations as it shall deem appropriate at any
time, continue to make its own credit decisions as to exercising or not
exercising from time to time any rights and privileges available to it under
this Agreement or any other Loan Document.

      SECTION 9.7. Copies, etc. The Administrative Agent shall give prompt
notice to each Lender of each notice or request required or permitted to be
given to the Administrative Agent by the Borrower pursuant to the terms of this
Agreement (unless concurrently delivered to the Lenders by the Borrower). The
Administrative Agent will distribute to each Lender each document or instrument
received for such Lender's account and copies of all other communications
received by the Administrative Agent from the Borrower for distribution to the
Lenders by the Administrative Agent in accordance with the terms of this
Agreement.

<PAGE>   104
      SECTION 9.8. The Syndication Agent, the Documentation Agent and the
Administrative Agent. Notwithstanding anything else to the contrary contained in
this Agreement or any other Loan Document, the Agents and the Documentation
Agent, in their respective capacities as such, each in such capacity, shall have
no duties or responsibilities under this Agreement or any other Loan Document
nor any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or otherwise exist against either Agent or the Documentation
Agent, as applicable, in such capacity except as are explicitly set forth herein
or in the other Loan Documents.


                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

      SECTION 10.1. Waivers, Amendments, etc. The provisions of this Agreement
and of each other Loan Document may from time to time be amended, modified or
waived, if such amendment, modification or waiver is in writing and consented to
by the Borrower and each Obligor party thereto and by the Required Lenders;
provided, however, that no such amendment, modification or waiver which would:

            (a) modify any requirement hereunder that any particular action be
      taken by all the Lenders or by the Required Lenders shall be effective
      unless consented to by each Lender;

            (b) modify this Section 10.1, or clause (i) of Section 10.10, change
      the definition of "Required Lenders", increase any Commitment Amount or
      the Percentage of any Lender (other than pursuant to clause (c) of Section
      2.1.2), reduce any fees described in Section 3.3 (other than the
      administration fee referred to in Section 3.3.2), release any Subsidiary
      Guarantor from its obligations under the Subsidiary Guaranty, if any,
      release all or substantially all of the collateral security (except in
      each case as otherwise specifically provided in this Agreement, any such
      Subsidiary Guaranty, a Security Agreement or a Pledge Agreement) or extend
      any Commitment Termination Date, shall be made without the consent of each
      Lender adversely affected thereby;

            (c) extend the due date for, or reduce the amount of, any scheduled
      repayment of principal of or interest on or fees payable in respect of any
      Loan or reduce the principal amount of or rate of interest on or fees
      payable in respect of any Loan or any Reimbursement Obligations (which
      shall in each case include the conversion of all or any part of the
      Obligations into equity of any Obligor), shall be made without the consent
      of the holder of the Note evidencing such Loan or, in the case of a
      Reimbursement Obligation, the Issuer owed, and those Lenders participating
      in, such Reimbursement Obligation;


                                       97
<PAGE>   105
            (d) affect adversely the interests, rights or obligations of any
      Agent, Issuer or Arranger (in its capacity as Agent, Issuer or Arranger),
      unless consented to by such Agent, Issuer or Arranger, as the case may be;

            (e) (i) change the definition of "Borrowing Base Amount", "Eligible
      Account", "Eligible Inventory" or "Net Asset Value" (in each case if the
      effect of such change would be to require a Lender to make or participate
      in a Credit Extension in an amount that is greater than such Lender would
      have had to make or participate in immediately prior to such change), (ii)
      amend, modify or waive Section 3.1.1(b) or (iii) have the effect (either
      immediately or at some later time) of enabling the Borrower to satisfy a
      condition precedent to the making of a Revolving Loan or the issuance of a
      Letter of Credit without the consent of Lenders holding at least 51% of
      the Revolving Loan Commitments; or

            (f) amend, modify or waive the provisions of clause (a)(i) of
      Section 3.1.1 or clause (b) of Section 3.1.2 or effect any amendment,
      modification or waiver that by its terms adversely affects the rights of
      Lenders participating in any Tranche differently from those of Lenders
      participating in other Tranches, without the consent of the holders of the
      Notes evidencing at least 51% of the aggregate amount of Loans outstanding
      under the Tranche or Tranches affected by such modification, or, in the
      case of a modification affecting the Revolving Loan Commitment Amount, the
      Lenders holding at least 51% of the Revolving Loan Commitments.

No failure or delay on the part of any Agent, the Issuer, any Lender or the
holder of any Note in exercising any power or right under this Agreement or any
other Loan Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further
exercise thereof or the exercise of any other power or right. No notice to or
demand on the Borrower in any case shall entitle it to any notice or demand in
similar or other circumstances. No waiver or approval by any Agent, the Issuer,
any Lender or the holder of any Note under this Agreement or any other Loan
Document shall, except as may be otherwise stated in such waiver or approval, be
applicable to subsequent transactions. No waiver or approval hereunder shall
require any similar or dissimilar waiver or approval thereafter to be granted
hereunder.

      SECTION 10.2. Notices. All notices and other communications provided to
any party hereto under this Agreement or any other Loan Document shall be in
writing or by facsimile and addressed, delivered or transmitted to such party at
its address or facsimile number set forth on Schedule II hereto or, in the case
of a Lender that becomes a party hereto after the date hereof, as set forth in
the Lender Assignment Agreement pursuant to which such Lender becomes a Lender
hereunder or at such other address or facsimile number as may be designated by
such party in a notice to the other parties. Any notice, if mailed and properly
addressed with postage prepaid or if properly addressed and sent by pre-paid
courier service, shall be deemed given when received; any notice, if transmitted
by facsimile, shall be deemed given when transmitted (and telephonic
confirmation of receipt thereof has been received).

<PAGE>   106
      SECTION 10.3. Payment of Costs and Expenses. The Borrower agrees to pay on
demand all reasonable expenses of each of the Agents (including the reasonable
fees and out-of-pocket expenses of a single counsel to the Agents and of local
or foreign counsel, if any, who may be retained by counsel to the Agents) in
connection with

            (a) the syndication by the Syndication Agent and the Arranger of the
      Loans, the negotiation, preparation, execution and delivery of this
      Agreement and of each other Loan Document, including schedules and
      exhibits, and any amendments, waivers, consents, supplements or other
      modifications to this Agreement or any other Loan Document as may from
      time to time hereafter be required, whether or not the transactions
      contemplated hereby are consummated;

            (b) the filing, recording, refiling or rerecording of each Mortgage,
      each Pledge Agreement and each Security Agreement and/or any Uniform
      Commercial Code financing statements relating thereto and all amendments,
      supplements and modifications to any thereof and any and all other
      documents or instruments of further assurance required to be filed or
      recorded or refiled or rerecorded by the terms hereof or of such Mortgage,
      Pledge Agreement or Security Agreement; and

            (c) the preparation and review of the form of any document or
      instrument relevant to this Agreement or any other Loan Document.

The Borrower further agrees to pay, and to save the Agents, the Issuer and the
Lenders harmless from all liability for, any stamp or other similar taxes which
may be payable in connection with the execution or delivery of this Agreement,
the Credit Extensions made hereunder or the issuance of the Notes or Letters of
Credit or any other Loan Documents. The Borrower also agrees to reimburse each
Agent, the Issuer and each Lender upon demand for all reasonable out-of-pocket
expenses (including reasonable attorneys' fees and legal expenses) incurred by
such Agent, the Issuer or such Lender in connection with (x) the negotiation of
any restructuring or "work-out", whether or not consummated, of any Obligations
and (y) the enforcement of any Obligations.

      SECTION 10.4. Indemnification. In consideration of the execution and
delivery of this Agreement by each Lender and the extension of the Commitments,
the Borrower hereby, to the fullest extent permitted under applicable law,
indemnifies, exonerates and holds each Agent, the Documentation Agent, the
Issuer, the Arranger and each Lender and each of their respective Affiliates,
and each of their respective partners, officers, directors, employees and
agents, and each other Person controlling any of the foregoing within the
meaning of either Section 15 of the Securities Act of 1933, as amended, or
Section 20 of the Securities Exchange Act of 1934, as amended (collectively, the
"Indemnified Parties"), free and harmless from and against any and all actions,
causes of action, suits, losses, costs, liabilities and damages, and expenses
actually incurred in connection therewith (irrespective of whether any such
Indemnified Party is a party to the action for which indemnification hereunder
is sought), including reasonable attorneys'


                                       99
<PAGE>   107
fees and disbursements (collectively, the "Indemnified Liabilities"), incurred
by the Indemnified Parties or any of them as a result of, or arising out of, or
relating to

            (a) any transaction financed or to be financed in whole or in part,
      directly or indirectly, with the proceeds of any Credit Extension;

            (b) the entering into and performance of this Agreement and any
      other Loan Document by any of the Indemnified Parties (excluding any
      successful action brought by or on behalf of the Borrower as the result of
      any failure by any Lender to make any Credit Extension hereunder);

            (c) any investigation, litigation or proceeding related to any
      acquisition or proposed acquisition by the Borrower or any of its
      Subsidiaries of all or any portion of the stock or assets of any Person,
      whether or not such Agent, such Documentation Agent, such Issuer, such
      Arranger or such Lender is party thereto;

            (d) any investigation, litigation or proceeding related to any
      environmental cleanup, audit, compliance or other matter relating to the
      Borrower's or any of its Subsidiaries' compliance with or liability under
      Environmental Law or the Release by the Borrower or any of its
      Subsidiaries of any Hazardous Material; or

            (e) the presence on or under, or the escape, seepage, leakage,
      spillage, discharge, emission or release from, any real property owned or
      operated by the Borrower or any Subsidiary thereof of any Hazardous
      Material present on or under such property in a manner giving rise to
      liability at or prior to the time the Borrower or such Subsidiary owned or
      operated such property (including any losses, liabilities, damages,
      injuries, costs, expenses or claims asserted or arising under any
      Environmental Law), regardless of whether caused by, or within the control
      of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or willful misconduct or any Hazardous Materials that are first
manufactured, emitted, generated, treated, released, stored or disposed of on
any real property of the Borrower or any of its Subsidiaries or any violation of
Environmental Law that first occurs on or with respect to any real property of
the Borrower or any of its Subsidiaries after such real property is transferred
to any Indemnified Person or its successor by foreclosure sale, deed in lieu of
foreclosure, or similar transfer, except to the extent such manufacture,
emission, release, generation, treatment, storage or disposal or violation is
actually caused by Holdings, the Borrower or any of the Borrower's Subsidiaries.
The Borrower and its permitted successors and assigns hereby waive, release and
agree not to make any claim, or bring any cost recovery action against, any
Agent, the Issuer, the Documentation Agent, the Arranger or any Lender under
CERCLA or any state equivalent, or any similar law now existing or hereafter
enacted, except to the extent arising out of the gross negligence or willful
misconduct of any Indemnified Party. It is expressly understood and agreed that
to the extent that any of such Persons is strictly liable under any
Environmental Laws, the Borrower's


                                       100
<PAGE>   108
obligation to such Person under this indemnity shall likewise be without regard
to fault on the part of the Borrower, to the extent permitted under applicable
law, with respect to the violation or condition which results in liability of
such Person. Notwithstanding anything to the contrary herein, each Agent, the
Documentation Agent, the Issuer, the Arranger and each Lender shall be
responsible with respect to any Hazardous Materials that are first manufactured,
emitted, generated, treated, released, stored or disposed of on any real
property of the Borrower or any of its Subsidiaries or any violation of
Environmental Law that first occurs on or with respect to any such real property
after such real property is transferred to any Agent, Documentation Agent,
Issuer, Arranger or Lender to its successor by foreclosure sale, deed in lieu of
foreclosure, or similar transfer, except to the extent such manufacture,
emission, release, generation, treatment, storage or disposal or violation is
actually caused by Holdings, the Borrower or any of the Borrower's Subsidiaries.
If and to the extent that the foregoing undertaking may be unenforceable for any
reason, the Borrower hereby agrees to make the maximum contribution to the
payment and satisfaction of each of the Indemnified Liabilities which is
permissible under applicable law.

      SECTION 10.5. Survival. The obligations of the Borrower under Sections
4.3, 4.4, 4.5, 4.6, 10.3 and 10.4, and the obligations of the Lenders under
Sections 4.8 and 9.1, shall in each case survive any termination of this
Agreement, the payment in full of all Obligations and the termination of all
Commitments. The representations and warranties made by the Borrower and each
other Obligor in this Agreement and in each other Loan Document shall survive
the execution and delivery of this Agreement and each such other Loan Document.

      SECTION 10.6. Severability. Any provision of this Agreement or any other
Loan Document which is prohibited or unenforceable in any jurisdiction shall, as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Agreement or such Loan Document or affecting the validity or enforceability
of such provision in any other jurisdiction.

      SECTION 10.7. Headings. The various headings of this Agreement and of each
other Loan Document are inserted for convenience only and shall not affect the
meaning or interpretation of this Agreement or such other Loan Document or any
provisions hereof or thereof.

      SECTION 10.8. Execution in Counterparts, Effectiveness, etc. This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be deemed to be an original and all of which shall constitute
together but one and the same agreement.

      SECTION 10.9. Governing Law; Entire Agreement. THIS AGREEMENT, THE NOTES
AND, EXCEPT TO THE EXTENT OTHERWISE EXPRESSLY PROVIDED THEREIN, EACH OTHER LOAN
DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY THE
INTERNAL LAWS OF THE STATE OF NEW YORK. This Agreement, the Notes and the other
Loan Documents constitute the entire understanding among the parties hereto with
respect to the subject matter


                                       101
<PAGE>   109
hereof and supersede any prior agreements, written or oral, with respect
thereto. Upon the execution and delivery of this Agreement by the parties
hereto, all obligations and liabilities of DLJ Merchant Banking II, Inc. under
or relating or with respect to the Commitment Letter shall be terminated and of
no further force or effect.

      SECTION 10.10. Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that (i) the Borrower may not assign
or transfer its rights or obligations hereunder without the prior written
consent of each of the Agents and all Lenders, and (ii) the rights of sale,
assignment and transfer of the Lenders are subject to Section 10.11.

      SECTION 10.11. Sale and Transfer of Loans and Notes; Participations in
Loans and Notes. Each Lender may assign, or sell participations in, its Loans
and Commitments to one or more other Persons, on a non pro rata basis (except as
provided below), in accordance with this Section 10.11.

      SECTION 10.11.1. Assignments. Any Lender (the "Assignor Lender"),

            (a) with the written consents of the Borrower, the Agents and (in
      the case of any assignment of participations in Letters of Credit or
      Revolving Loan Commitments) the Issuer (which consents shall not be
      unreasonably delayed or withheld and which consents of the Agents and the
      Issuer shall not be required in the case of assignments made by DLJ or any
      of its Affiliates), may at any time assign and delegate to one or more
      commercial banks or other financial institutions or funds which are
      regularly engaged in making, purchasing or investing in loans or
      securities, and

            (b) with notice to the Borrower, the Agents, and (in the case of any
      assignment of participations in Letters of Credit or Revolving Loan
      Commitments) the Issuer, but without the consent of the Borrower, the
      Agents or the Issuer, may assign and delegate to any of its Affiliates or
      to any other Lender

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an "Assignee Lender"), all or any fraction of such Lender's total Loans,
participations in Letters of Credit and Letter of Credit Outstandings with
respect thereto and Commitments (which assignment and delegation shall be, as
among Revolving Loan Commitments, Revolving Loans and participations in Letters
of Credit, of a constant, and not a varying, percentage) in a minimum aggregate
amount of (i) $5,000,000 or (ii) the then remaining amount of such Lender's
Loans and Commitments; provided, however, that any such Assignee Lender will
comply, if applicable, with the provisions contained in Section 4.6 and the
Borrower, each other Obligor and the Agents shall be entitled to continue to
deal solely and directly with such Lender in connection with the interests so
assigned and delegated to an Assignee Lender until


                                       102
<PAGE>   110
            (c) written notice of such assignment and delegation, together with
      payment instructions, addresses and related information with respect to
      such Assignee Lender, shall have been given to the Borrower and the Agents
      by such Lender and such Assignee Lender;

            (d) such Assignee Lender shall have executed and delivered to the
      Borrower and the Agents a Lender Assignment Agreement, accepted by the
      Agents;

            (e) the processing fees described below shall have been paid; and

            (f) the Agent shall have registered such assignment and delegation
      in the Register pursuant to clause (b) of Section 2.7.

From and after the date that the Agents accept such Lender Assignment Agreement
and such assignment and delegation is registered in the Register pursuant to
clause (b) of Section 2.7, (x) the Assignee Lender thereunder shall be deemed
automatically to have become a party hereto and to the extent that rights and
obligations hereunder have been assigned and delegated to such Assignee Lender
in connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents, and (y)
the Assignor Lender, to the extent that rights and obligations hereunder have
been assigned and delegated by it in connection with such Lender Assignment
Agreement, shall be released from its obligations hereunder and under the other
Loan Documents. Within ten Business Days after its receipt of notice that the
Administrative Agent has received an executed Lender Assignment Agreement, the
Borrower shall execute and deliver to the Administrative Agent (for delivery to
the relevant Assignee Lender) new Notes evidencing such Assignee Lender's
assigned Loans and Commitments and, if the Assignor Lender has retained Loans
and Commitments hereunder, replacement Notes in the principal amount of the
Loans and Commitments retained by the Assignor Lender hereunder (such Notes to
be in exchange for, but not in payment of, those Notes then held by such
Assignor Lender). Each such Note shall be dated the date of the predecessor
Notes. The Assignor Lender shall mark the predecessor Notes "exchanged" and
deliver them to the Borrower. Accrued interest on that part of the predecessor
Notes evidenced by the new Notes, and accrued fees, shall be paid as provided in
the Lender Assignment Agreement. Accrued interest on that part of the
predecessor Notes evidenced by the replacement Notes shall be paid to the
Assignor Lender. Accrued interest and accrued fees shall be paid at the same
time or times provided in the predecessor Notes and in this Agreement. Such
Assignor Lender or such Assignee Lender (unless the Assignor Lender or the
Assignee Lender is DLJ or one of its Affiliates) must also pay a processing fee
to the Administrative Agent upon delivery of any Lender Assignment Agreement in
the amount of $3,000, unless such assignment and delegation is by a Lender to
its Affiliate or if such assignment and delegation is by a Lender to a Federal
Reserve Bank, as provided below or is otherwise consented to by the
Administrative Agent. Any attempted assignment and delegation not made in
accordance with this Section 10.11.1 shall be null and void. Nothing contained
in this Section 10.11.1 shall prevent or prohibit any Lender from pledging its
rights (but not its obligations to make Loans or participate in Letters of
Credit of Letter of Credit Outstandings) under this Agreement and/or its Loans
and/or its Notes


                                       103
<PAGE>   111
hereunder to a Federal Reserve Bank in support of borrowings made by such Lender
from such Federal Reserve Bank. In the event that S&P, Moody's or Thompson's
BankWatch (or InsuranceWatch Ratings Service, in the case of Lenders that are
insurance companies (or Best's Insurance Reports, if such insurance company is
not rated by Insurance Watch Ratings Service)) shall, after the date that any
Lender with a Commitment to make Revolving Loans or participate in Letters of
Credit becomes a Lender, downgrade the long-term certificate of deposit rating
or long-term senior unsecured debt rating of such Lender, and the resulting
rating shall be below BBB-, Baa3 or C (or BB, in the case of Lender that is an
insurance company (or B, in the case of an insurance company not rated by
InsuranceWatch Ratings Service)) respectively, then the Issuer or the Borrower
(with the consent of the Agents and the Issuer) shall have the right, but not
the obligation, upon notice to such Lender and the Agents, to replace such
Lender with an Assignee Lender in accordance with and subject to the
restrictions contained in this Section, and such Lender hereby agrees to
transfer and assign without recourse (in accordance with and subject to the
restrictions contained in this Section) all its interests, rights and
obligations in respect of its Revolving Loan Commitment under this Agreement to
such Assignee Lender; provided, however, that (i) no such assignment shall
conflict with any law, rule, regulation or order of any governmental authority
and (ii) such Assignee Lender shall pay to such Lender in immediately available
funds on the date of such assignment the principal of and interest and fees (if
any) accrued to the date of payment on the Loans made, and Letters of Credit
participated in, by such Lender hereunder and all other amounts accrued for such
Lender's account or owed to it hereunder.

      SECTION 10.11.2. Participations. Any Lender may at any time sell to one or
more commercial banks or other Persons (each such commercial bank and other
Person being herein called a "Participant") participating interests in any of
the Loans, Commitments, participations in Letters of Credit and Letters of
Credit Outstandings or other interests of such Lender hereunder; provided,
however, that

            (a) no participation contemplated in this Section shall relieve such
      Lender from its Commitments or its other obligations hereunder or under
      any other Loan Document;

            (b) such Lender shall remain solely responsible for the performance
      of its Commitments and such other obligations;

            (c) the Borrower and each other Obligor and the Agents shall
      continue to deal solely and directly with such Lender in connection with
      such Lender's rights and obligations under this Agreement and each of the
      other Loan Documents;

            (d) no Participant, unless such Participant is an Affiliate of such
      Lender, or is itself a Lender, shall be entitled to require such Lender to
      take or refrain from taking any action hereunder or under any other Loan
      Document, except that such Lender may agree with any Participant that such
      Lender will not, without such Participant's consent, agree to (i) any
      reduction in the interest rate or amount of fees that such Participant is
      otherwise entitled to, (ii) a decrease in the principal amount, or an
      extension of the final Stated


                                       104
<PAGE>   112
      Maturity Date, of any Loan in which such Participant has purchased a
      participating interest or (iii) a release of all or substantially all of
      the collateral security under the Loan Documents or any Subsidiary
      Guarantor under any Subsidiary Guaranty, if any, in each case except as
      otherwise specifically provided in a Loan Document; and

            (e) the Borrower shall not be required to pay any amount under
      Sections 4.3, 4.4, 4.5, 4.6, 10.3 and 10.4 that is greater than the amount
      which it would have been required to pay had no participating interest
      been sold.

The Borrower acknowledges and agrees, subject to clause (e) above, that, to the
fullest extent permitted under applicable law, each Participant, for purposes of
Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 10.3 and 10.4, shall be considered a
Lender.

      SECTION 10.12. Other Transactions. Nothing contained herein shall preclude
any Agent or any other Lender from engaging in any transaction, in addition to
those contemplated by this Agreement or any other Loan Document, with the
Borrower or any of its Affiliates in which the Borrower or such Affiliate is not
restricted hereby from engaging with any other Person.

      SECTION 10.13. Forum Selection and Consent to Jurisdiction. ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE LENDERS, THE ISSUER OR
THE BORROWER RELATING THERETO SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY (TO
THE EXTENT PERMITTED UNDER APPLICABLE LAW) IN THE COURTS OF THE STATE OF NEW
YORK, NEW YORK COUNTY, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT
AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE
AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER
PROPERTY MAY BE FOUND. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK, NEW YORK COUNTY, AND OF
THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE
PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE
BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION. THE
BORROWER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL,
POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK.
THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE
LAYING OF VENUE OF ANY SUCH


                                       105
<PAGE>   113
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT
THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY
COURT OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT
PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES (TO THE EXTENT
PERMITTED UNDER APPLICABLE LAW) SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS
UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

      SECTION 10.14. Waiver of Jury Trial. THE AGENTS, THE ISSUER, THE LENDERS
AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE LENDERS OR THE BORROWER
RELATING THERETO. THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL
AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF
EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A
MATERIAL INDUCEMENT FOR THE AGENTS AND THE LENDERS ENTERING INTO THIS AGREEMENT
AND EACH SUCH OTHER LOAN DOCUMENT.

      SECTION 10.15. Confidentiality. The Agents, the Issuer, the Arranger and
the Lenders shall hold all non-public information obtained pursuant to or in
connection with this Agreement or obtained by them based on a review of the
books and records of the Borrower or any of its Subsidiaries in accordance with
their customary procedures for handling confidential information of this nature,
but may make disclosure to any of their examiners, regulators (including,
without limitation, the National Association of Insurance Commissioners),
Affiliates, outside auditors, counsel and other professional advisors in
connection with this Agreement or as reasonably required by any potential bona
fide transferee, participant or assignee, or in connection with the exercise of
remedies under a Loan Document, or as requested by any governmental agency or
representative thereof or pursuant to legal process; provided, however, that

            (a) unless specifically prohibited by applicable law or court order,
      each Agent, the Arranger and each Lender shall promptly notify the
      Borrower of any request by any governmental agency or representative
      thereof (other than any such request in connection with an examination of
      the financial condition of such Agent, the Issuer, Arranger and


                                       106
<PAGE>   114
      Lender by such governmental agency) for disclosure of any such non-public
      information and, where practicable, prior to disclosure of such
      information;

            (b) prior to any such disclosure pursuant to this Section 10.15,
      each Agent, the Issuer, the Arranger and each Lender shall require any
      such bona fide transferee, participant and assignee receiving a disclosure
      of non-public information to agree in writing

                  (i) to be bound by this Section 10.15; and

                  (ii) to require such Person to require any other Person to
            whom such Person discloses such non-public information to be
            similarly bound by this Section 10.15;

            (c) disclosure may, with the consent of the Agents and the Borrower,
      be made by any Lender to any direct or indirect contractual counterparties
      of such Lender in swap agreements or such contractual counterparties'
      professional advisors; provided that such contractual counterparty or
      professional advisor agrees in writing to keep such information
      confidential to the same extent required of the Lenders hereunder; and

            (d) except as may be required by an order of a court of competent
      jurisdiction and to the extent set forth therein, no Lender shall be
      obligated or required to return any materials furnished by the Borrower or
      any Subsidiary.

                               DISCLOSURE SCHEDULE



ITEM 6.7  Litigation.

      1.    On April 30, 1997, the United States District Court for the Southern
            District of New York granted the joint motion of the U.S. Department
            of Justice and IBM, approving the proposed settlement of the IBM
            Consent Decree litigation. As summary of the terms of the
            settlement, and the possible effects on the Borrower's business, is
            set forth on pages 8-9 of the Holdings' 10-K filed with the
            Securities and Exchange Commission for the Fiscal Year ended June
            30, 1996.

      2.    In Data Study, Inc. v. DecisionOne, the plaintiff filed suit against
            the Borrower for unpaid invoices in the amount of approximately
            $450,000 relating to a software development contract; the Borrower
            counterclaimed, alleging failure of performance by Data Study.


ITEM 6.8 Existing Subsidiaries.

            IC Properties Corporation (Delaware)
            Properties Development Corporation (Delaware)
            Properties Holding Corporation (Delaware)
            Decision Data Investment Corporation (Delaware)
            DecisionOne Supplies, Inc. (Delaware)
            Decision Data International Corporation (Delaware)
            Decision Data Computer International S.A. (Switzerland)
            DecisionOne Corporation (Canada)


ITEM 6.11  Employee Benefit Plans.

      Underfunded Pension Plan

            In 1988 the Borrower assumed the liability of a defined benefit
      pension plan applicable to employees of a company acquired in 1988. The
      eligibility and benefits were frozen in 1988. The Plan is underfunded as
      the projected benefit obligations exceed the fair value of the Plan assets
      by approximately $1.3 million as of June 30, 1996. For a further
      discussion, see footnote 16 to the Notes to the Consolidated Financial
      Statements

      of the Borrower appearing in the Holdings' 10-K filed with the Securities
      and Exchange and Exchange Commission for the Fiscal Year ended June 30,
      1996.


ITEM 6.12 Environmental Matters.

            The Borrower, or certain businesses as to which it is alleged that
      the Borrower is a successor, have been identified as potentially
      responsible parties in respect of four waste disposal sites that have been
      identified by the United States Environmental Protection Agency as
      Superfund sites. In addition, the Borrower received a notice several years
      ago that it may be a potentially responsible party with respect to a fifth
      related site, but has not received any other communication with respect to
      that site. Under applicable law, all parties responsible for disposal of
      hazardous substances at those sites are jointly and severally liable for
      clean up costs. The Borrower originally estimated that its share of the
      costs of the clean-up of one of these sites would be approximately
      $500,000 which is provided for in liabilities related to the discontinued
      products division in the Holdings consolidated balance sheets as of June
      30, 1995 and 1996. Complete information as to the scope of required
      clean-up at these sites is not yet available and, therefore, the
      Borrower's evaluation may be affected as further information becomes
      available.
