                        (b)     Anything to the contrary in this Section 2.1

amounts, and with respect to such matters, as Agent in its Permitted Discretion
shall deem necessary or appropriate, against the Borrowing Base, including,

leased assets, rents or other amounts payable under such leases) and has failed
to pay under any Section of this Agreement or any other Loan Document, and (ii)
amounts owing by Borrower to any Person to the extent secured by a Lien on, or
trust over, any of the Collateral (other than any existing Permitted Lien set
forth on Schedule P-1 which is specifically identified thereon as entitled to
have priority over Agent's Liens), which Lien or trust, in the Permitted
Discretion of Agent likely would have a priority superior to the Agent's Liens
(such as Liens or trusts in favor of landlords, warehousemen, carriers,

Advances in the amount of $5,000,000. Amounts borrowed pursuant to this Section

severally) to make term loans (collectively, the "Closing Date Term Loan") to
Borrower in an amount equal to such Lender's Pro Rata Share of the Term Loan
Amount on the Closing Date less the amount of the Term Loan Holdback. In
addition, subject to the terms and conditions of this Agreement and the Final
Bankruptcy Court Order, on the Revolver Facility Effective Date, each Lender

Lender's Pro Rata Share of the Term Loan Amount on the Revolver Facility
Effective Date less the sum of (i) amount of the Closing Date Term Loan made on

                        (b)     A portion of the Term Loan Amount equal to
$8,000,000 (the "Term Loan Holdback") shall not be available to the Borrower
until the Agent is satisfied, in its Permitted Discretion, that either the
mechanics or contractors Liens set forth on Schedule P-1 to this Agreement are
released or the obligations secured by such mechanics or contractors Liens have
been satisfied. If the Agent determines in its Permitted Discretion that any
such mechanics or contractors Liens are released or any obligations secured by
such mechanics or contractors Liens are satisfied, the Agent shall release a
portion of the Term Loan Holdback in the amount corresponding on Schedule P-1 to
the Liens released or the obligations satisfied. Upon any such release, each
Lender with a Term Loan Commitment agrees (severally and not jointly and
severally) to make an additional term loan to the Borrower in an amount
corresponding to the amount of the Term Loan Holdback released by the Agent,
provided that (i) the conditions contained in Section 3.4 are satisfied on the
date of any such additional term loan and (ii) such additional term loans made
in connection with a release of a portion of the Term Loan Holdback shall not be
made more frequently than once each week and shall not be for an amount of less
than $1,000,000 unless the Term Loan Holdback then in effect is less than
$1,000,000. The additional term loans made pursuant to this Section 2.2(b) in
connection with any release of a portion of the Term Loan Holdback shall
constitute a part of the Term Loan for all purposes of this Agreement.

                        (c)     The outstanding unpaid principal balance and all
accrued and unpaid interest under the Term Loan shall be due and payable on the
Maturity Date, whether by the terms of this Agreement, by prepayment, or by
acceleration. All amounts outstanding under the Term Loan shall constitute
Obligations.

                2.3     Borrowing Procedures and Settlements.

                        (a)     Procedure for Borrowing. Each Borrowing shall be
made by an irrevocable written request by an Authorized Person delivered to
Agent (which notice must be received by Agent no later than 10:00 a.m.
(California time) on the Business Day prior to the date that is the requested
Funding Date in the case of a request for an Advance or the Term Loan specifying
(i) the amount of such Borrowing, and (ii) the requested Funding Date, which
shall be a Business Day; provided, however, that in the case of a request for a
Swing Loan in an amount of $2,000,000, or less, such notice will be timely
received if it is received by Agent no later than 10:00 a.m. (California time)
on the Business Day that is the requested Funding Date) specifying (i) the
amount of such Borrowing, and (ii) the requested Funding Date, which shall be a
Business Day. At Agent's election, in lieu of delivering the above-described
written request, any Authorized Person may give Agent telephonic notice of such
request by the required time, with such telephonic notice to be confirmed in
writing within 24 hours of the giving of such notice.

                        (b)     Agent's Election. Promptly after receipt of a
request for a Borrowing pursuant to Section 2.3(a), Agent shall elect, in its
discretion, (i) to have the terms of Section 2.3(c) apply to such requested
Borrowing, or the terms of Section 2.3(d) in the amount of the requested
Borrowing, or (ii) if the Borrowing is for an Advance, to request Swing Lender
to make a Swing Loan pursuant to the terms of Section 2.3(d) in the amount of
the requested Borrowing; provided, however, that if Swing Lender declines in its
sole discretion to make a Swing Loan pursuant to Section 2.3(d), Agent shall
elect to have the terms of Section 2.3(c) apply to such requested Borrowing.



                                      -23-
<PAGE>   30


                (c)     Making of Advances.

                        (i)     In the event that Agent shall elect to have the
        terms of this Section 2.3(c) apply to a requested Borrowing as described
        in Section 2.3(b), then promptly after receipt of a request for a
        Borrowing pursuant to Section 2.3(a), Agent shall notify the Lenders,
        not later than 1:00 p.m. (California time) on the Business Day
        immediately preceding the Funding Date applicable thereto, by telecopy,
        telephone, or other similar form of transmission, of the requested
        Borrowing. Each Lender shall make the amount of such Lender's Pro Rata
        Share of the requested Borrowing available to Agent in immediately
        available funds, to Agent's Account, not later than 10:00 a.m.
        (California time) on the Funding Date applicable thereto. After Agent's
        receipt of the proceeds of such Advances (or the Term Loan, as
        applicable), upon satisfaction of the applicable conditions precedent
        set forth in Section 3 hereof, Agent shall make the proceeds thereof
        available to Borrower on the applicable Funding Date by transferring
        immediately available funds equal to such proceeds received by Agent to
        Borrower's Designated Account; provided, however, that, subject to the
        provisions of Section 2.3(i), Agent shall not request any Lender to
        make, and no Lender shall have the obligation to make, any Advance (or
        its portion of the Term Loan) if Agent shall have actual knowledge that
        (1) one or more of the applicable conditions precedent set forth in
        Section 3 will not be satisfied on the requested Funding Date for the
        applicable Borrowing unless such condition has been waived, or (2) the
        requested Borrowing would exceed the Availability on such Funding Date.

                        (ii)    Unless Agent receives notice from a Lender on or
        prior to the Closing Date or, with respect to any Borrowing after the
        Closing Date, at least 1 Business Day prior to the date of such
        Borrowing, that such Lender will not make available as and when required
        hereunder to Agent for the account of Borrower the amount of that
        Lender's Pro Rata Share of the Borrowing, Agent may assume that each
        Lender has made or will make such amount available to Agent in
        immediately available funds on the Funding Date and Agent may (but shall
        not be so required), in reliance upon such assumption, make available to
        Borrower on such date a corresponding amount. If and to the extent any
        Lender shall not have made its full amount available to Agent in
        immediately available funds and Agent in such circumstances has made
        available to Borrower such amount, that Lender shall on the Business Day
        following such Funding Date make such amount available to Agent,
        together with interest at the Defaulting Lender Rate for each day during
        such period. A notice submitted by Agent to any Lender with respect to
        amounts owing under this subsection shall be conclusive, absent manifest
        error. If such amount is so made available, such payment to Agent shall
        constitute such Lender's portion of the requested Advance on the date of
        Borrowing for all purposes of this Agreement. If such amount is not made
        available to Agent on the Business Day following the Funding Date, Agent
        will notify Borrower of such failure to fund and, upon demand by Agent,
        Borrower shall pay such amount to Agent for Agent's account, together
        with interest thereon for each day elapsed since the date of such
        Borrowing, at a rate per annum equal to the interest rate applicable at
        the time to the Advances composing such Borrowing. The failure of any
        Lender to make its portion of any Advance on any Funding Date shall not
        relieve any other Lender of any obligation hereunder to make available
        its portion of the requested Advance on such Funding Date,



                                      -24-
<PAGE>   31


        but no Lender shall be responsible for the failure of any other Lender
        to make its portion of the requested Advance to be made by such other
        Lender on any Funding Date.

                        (iii)   Agent shall not be obligated to transfer to a
        Defaulting Lender any payments made by Borrower to Agent for the
        Defaulting Lender's benefit, and, in the absence of such transfer to the
        Defaulting Lender, Agent shall transfer any such payments to each other
        non-Defaulting Lender member of the Lender Group ratably in accordance
        with their Commitments (but only to the extent that such Defaulting
        Lender's Advance was funded by the other members of the Lender Group)
        or, if so directed by Borrower and if no Default or Event of Default had
        occurred and is continuing (and to the extent such Defaulting Lender's
        portion of the Advance was not funded by the Lender Group), retain the
        same to be re-advanced to Borrower as if such Defaulting Lender had made
        Advances to Borrower. Subject to the foregoing, Agent may hold and, in
        its Permitted Discretion, re-lend to Borrower for the account of such
        Defaulting Lender the amount of all such payments received and retained
        by it for the account of such Defaulting Lender. Solely for the purposes
        of voting or consenting to matters with respect to the Loan Documents,
        such Defaulting Lender shall be deemed not to be a "Lender" and such
        Lender's Commitment shall be deemed to be zero. This Section shall
        remain effective with respect to such Lender until (x) the Obligations
        under this Agreement shall have been declared or shall have become
        immediately due and payable, (y) the non-Defaulting Lenders, Agent, and
        Borrower shall have waived such Defaulting Lender's default in writing,
        or (z) the Defaulting Lender makes its Pro Rata Share of the applicable
        Advance and pays to Agent all amounts owing by Defaulting Lender in
        respect thereof. The operation of this Section shall not be construed to
        increase or otherwise affect the Commitment of any Lender, to relieve or
        excuse the performance by such Defaulting Lender or any other Lender of
        its duties and obligations hereunder, or to relieve or excuse the
        performance by Borrower of its duties and obligations hereunder to Agent
        or to Lenders other than such Defaulting Lender. Any such failure to
        fund by any Defaulting Lender shall constitute a material breach by such
        Defaulting Lender of this Agreement and shall entitle Borrower at its
        option, upon written notice to Agent, to arrange for a substitute Lender
        to assume the Commitment of such Defaulting Lender, such substitute
        Lender to be acceptable to Agent. In connection with the arrangement of
        such a substitute Lender, the Defaulting Lender shall have no right to
        refuse to be replaced hereunder, and agrees to execute and deliver a
        completed form of Assignment and Acceptance in favor of the substitute
        Lender (and agrees that it shall be deemed to have executed and
        delivered such document if it fails to do so) subject only to being
        repaid its share of the outstanding Obligations (including an assumption
        of its Pro Rata Share of the Risk Participation Liability) without any
        premium or penalty of any kind whatsoever; provided further, however,
        that any such assumption of the Commitment of such Defaulting Lender
        shall not be deemed to constitute a waiver of any of Lender Groups' or
        Borrower's rights or remedies against any such Defaulting Lender arising
        out of or in relation to such failure to fund.

                (d)     Making of Swing Loans.

                        (i)     In the event Agent shall elect, with the consent
        of Swing Lender, as a Lender, to have the terms of this Section 2.3(d)
        apply to a requested

        Borrowing as described in Section 2.3(b), Swing Lender as a Lender shall
        make such Advance in the amount of such Borrowing (any such Advance made
        solely by Swing Lender as a Lender pursuant to this Section 2.3(d) being
        referred to as a "Swing Loan" and such Advances being referred to
        collectively as "Swing Loans") available to Borrower on the Funding Date
        applicable thereto by transferring immediately available funds to
        Borrower's Designated Account. Each Swing Loan is an Advance hereunder
        and shall be subject to all the terms and conditions applicable to other
        Advances, except that all payments on any Swing Loan shall be payable to
        Swing Lender as a Lender solely for its own account (and for the account
        of the holder of any participation interest with respect to such Swing
        Loan). Subject to the provisions of Section 2.3(i), Agent shall not
        request Swing Lender as a Lender to make, and Swing Lender as a Lender
        shall not make, any Swing Loan if Agent has actual knowledge that (i)
        one or more of the applicable conditions precedent set forth in Section
        3 will not be satisfied on the requested Funding Date for the applicable
        Borrowing unless such condition has been waived, or (ii) the requested
        Borrowing would exceed the Availability on such Funding Date. Swing
        Lender as a Lender shall not otherwise be required to determine whether
        the applicable conditions precedent set forth in Section 3 have been
        satisfied on the Funding Date applicable thereto prior to making, in its
        sole discretion, any Swing Loan.

                        (ii)    The Swing Loans shall be secured by the Agent's
        Liens, shall constitute Advances and Obligations hereunder, and shall
        bear interest at the rate applicable from time to time to Advances.

                (e)     Agent Advances.

                        (i)     Agent hereby is authorized by Borrower and the
        Lenders, from time to time after the Revolver Facility Effective Date,
        in Agent's sole discretion, (1) after the occurrence and during the
        continuance of a Default or an Event of Default, or (2) at any time that
        any of the other applicable conditions precedent set forth in Section 3
        have not been satisfied, to make Advances to Borrower on behalf of the
        Lenders that Agent, in its Permitted Discretion deems necessary or
        desirable (A) to preserve or protect the Collateral, or any portion
        thereof, (B) to enhance the likelihood of repayment of the Obligations,
        or (C) to pay any other amount chargeable to Borrower pursuant to the
        terms of this Agreement, including Lender Group Expenses and the costs,
        fees, and expenses described in Section 10 (any of the Advances
        described in this Section 2.3(e)shall be referred to as "Agent
        Advances"), provided, that notwithstanding anything to the contrary
        contained in this Section 2.3(e), the aggregate principal amount of
        Agent Advances outstanding at any one time, when taken together with the
        aggregate principal amount of Overadvances made in accordance with
        Section 2.3(i) outstanding at any time, shall not exceed an amount equal
        to the lesser of (x) 10% of the Borrowing Base then in effect and (y)
        $5,000,000. Each Agent Advance is an Advance hereunder and shall be
        subject to all the terms and conditions applicable to other Advances,
        except that all payments thereon shall be payable to Agent solely for
        its own account (and for the account of the holder of any participation
        interest with respect to such Agent Advance).

                        (ii)    The Agent Advances shall be repayable by
        Borrower on demand and secured by the Agent's Liens granted to Agent
        under the Loan Documents,



                                      -26-

        shall constitute Advances and Obligations hereunder, and shall bear
        interest at the rate applicable from time to time to Advances.

                        (f)     Settlement. It is agreed that each Lender's
funded portion of the Advances is intended by the Lenders to equal, at all
times, such Lender's Pro Rata Share of the outstanding Advances. Such agreement
notwithstanding, Agent, Swing Lender, and the other Lenders agree (which
agreement shall not be for the benefit of or enforceable by Borrower) that in
order to facilitate the administration of this Agreement and the other Loan
Documents, settlement among them as to the Advances, the Swing Loans, and the
Agent Advances shall take place on a periodic basis in accordance with the
following provisions:

                                (i)     Agent shall request settlement
        ("Settlement") with the Lenders on a weekly basis, or on a more frequent
        basis if so determined by Agent, (1) on behalf of Swing Lender, with
        respect to each outstanding Swing Loan, (2) for itself, with respect to
        each Agent Advance, and (3) with respect to Collections received by the
        Agent, as to each by notifying the Lenders by telecopy, telephone, or
        other similar form of transmission, of such requested Settlement, no
        later than 2:00 p.m. (California time) on the Business Day immediately
        prior to the date of such requested Settlement (the date of such
        requested Settlement being the "Settlement Date"). Such notice of a
        Settlement Date shall include a summary statement of the amount of
        outstanding Advances, Swing Loans, and Agent Advances for the period
        since the prior Settlement Date. Subject to the terms and conditions
        contained herein (including Section 2.3(c)(iii)): (y) if a Lender's
        balance of the Advances, the Swing Loans, and Agent Advances exceeds
        such Lender's Pro Rata Share of the Advances, the Swing Loans, and Agent
        Advances as of a Settlement Date, then Agent shall, by no later than
        12:00 noon (California time) on the Settlement Date, transfer in
        immediately available funds to the account of such Lender as such Lender
        may designate, an amount such that each such Lender shall, upon receipt
        of such amount, have as of the Settlement Date, its Pro Rata Share of
        the Advances, the Swing Loans, and Agent Advances; and (z) if a Lender's
        balance of the Advances, the Swing Loans, and Agent Advances is less
        than such Lender's Pro Rata Share of the Advances, the Swing Loans, and
        Agent Advances as of a Settlement Date, such Lender shall no later than
        12:00 noon (California time) on the Settlement Date transfer in
        immediately available funds to Agent's Account, an amount such that each
        such Lender shall, upon transfer of such amount, have as of the
        Settlement Date, its Pro Rata Share of the Advances, Swing Loans, and
        Agent Advances. Such amounts made available to Agent under clause (z) of
        the immediately preceding sentence shall be applied against the amounts
        of the applicable Swing Loan or Agent Advance and, together with the
        portion of such Swing Loan or Agent Advance representing Swing Lender's
        Pro Rata Share thereof, shall constitute Advances of such Lenders. If
        any such amount is not made available to Agent by any Lender on the
        Settlement Date applicable thereto to the extent required by the terms
        hereof, Agent shall be entitled to recover for its account such amount
        on demand from such Lender together with interest thereon at the
        Defaulting Lender Rate.

                                (ii)    In determining whether a Lender's
        balance of the Advances, Swing Loans, and Agent Advances is less than,
        equal to, or greater than such Lender's Pro Rata Share of the Advances,
        Swing Loans, and Agent Advances as of a



                                      -27-
<PAGE>   34


        Settlement Date, Agent shall, as part of the relevant Settlement, apply
        to such balance the portion of payments actually received in good funds
        by Agent with respect to principal, interest, fees payable by Borrower
        and allocable to the Lenders hereunder, and proceeds of Collateral. To
        the extent that a net amount is owed to any such Lender after such
        application, such net amount shall be distributed by Agent to that
        Lender as part of such next Settlement.

                                (iii)   Between Settlement Dates, Agent, to the
        extent no Agent Advances or Swing Loans are outstanding, may pay over to
        Swing Lender any payments received by Agent, that in accordance with the
        terms of this Agreement would be applied to the reduction of the
        Advances, for application to Swing Lender's Pro Rata Share of the
        Advances. If, as of any Settlement Date, Collections received since the
        then immediately preceding Settlement Date have been applied to Swing
        Lender's Pro Rata Share of the Advances other than to Swing Loans, as
        provided for in the previous sentence, Swing Lender shall pay to Agent
        for the accounts of the Lenders, and Agent shall pay to the Lenders, to
        be applied to the outstanding Advances of such Lenders, an amount such
        that each Lender shall, upon receipt of such amount, have, as of such
        Settlement Date, its Pro Rata Share of the Advances. During the period
        between Settlement Dates, Swing Lender with respect to Swing Loans,
        Agent with respect to Agent Advances, and each Lender (subject to the
        effect of letter agreements between Agent and individual Lenders) with
        respect to the Advances other than Swing Loans and Agent Advances, shall
        be entitled to interest at the applicable rate or rates payable under
        this Agreement on the daily amount of funds employed by Swing Lender,
        Agent, or the Lenders, as applicable.

                        (g)     Notation. Agent shall record on its books the
principal amount of the Advances owing to each lender, including the Swing Loans
owing to Swing Lender, and Agent Advances owing to Agent, and the interests
therein of each Lender, from time to time. In addition, each Lender is
authorized, at such Lender's option, to note the date and amount of each payment
or prepayment of principal of such Lender's Advances in its books and records,
including computer records, such books and records constituting conclusive
evidence, absent manifest error, of the accuracy of the information contained
therein.

                        (h)     Lenders' Failure to Perform. All Advances (other
than Swing Loans and Agent Advances) shall be made by Lenders contemporaneously
and in accordance with their Pro Rata Shares. It is understood that (i) no
Lender shall be responsible for any failure by any other Lender to perform its
obligation to make any Advance (or other extension of credit) hereunder, nor
shall any Commitment of any Lender be increased or decreased as a result of any
failure by any other Lender to perform its obligations hereunder, and (ii) no
failure by any Lender to perform its obligations hereunder shall excuse any
other Lender from its obligations hereunder.

                        (i)     Optional Overadvances. Any contrary provision of
this Agreement notwithstanding, the Lenders hereby authorize Agent or Swing
Lender, as applicable, and Agent or Swing Lender, as applicable, may, but is not
obligated to, knowingly and intentionally, continue to make Advances (including
Swing Loans) to Borrower notwithstanding that an Overadvance exists or thereby
would be created, so long as (i) after giving effect to such Advances (including
Swing Loans), the outstanding Revolver Usage does not exceed the



                                      -28-

<PAGE>   35
Borrowing Base by more than an amount equal to the lesser of (A) 10% of the
Borrowing Base then in effect and (B) $5,000,000, (ii) after giving effect to
such Advances (including Swing Loans) the outstanding Revolver Usage (except for
and excluding amounts charged to the Loan Account for interest, fees, or Lender
Group Expenses) does not exceed the Maximum Revolver Amount, (iii) the aggregate
principal amount of Overadvances made pursuant to this Section 2.3(i) when taken
together with the aggregate principal amount of Agent Advances made pursuant to
Section 2.3(e) does not exceed at any time an amount equal to the lesser of (1)
10% of the Borrowing Base then in effect and (2) $5,000,000, at the time of the
making of any such Advance (including any Swing Loan), Agent does not believe,
in good faith, that the Overadvance created by such Advance will be outstanding
for more than 90 days, provided that, prior to the Revolver Facility Effective
Date, clauses (i) and (iii) shall not be applicable. The foregoing provisions
are for the exclusive benefit of Agent, Swing lender, and the Lenders and are
not intended to benefit Borrower in any way. The Advances and Swing Loans, as
applicable, that are made pursuant to this Section 2.3(i) shall be subject to
the same terms and conditions as any other Advance or Swing Loan, as applicable,
except that the rate of interest applicable thereto shall be the rate applicable
to Advances under Section 2.6(c) hereof without regard to the presence or
absence of a Default or Event of Default.

                                (i)     In the event Agent obtains actual
        knowledge that the Revolver Usage exceeds the amounts permitted by the
        preceding paragraph, regardless of the amount of, or reason for, such
        excess, Agent shall notify Lenders as soon as practicable (and prior to
        making any (or any additional) intentional Overadvances (except for and
        excluding amounts charged to the Loan Account for interest, fees, or
        Lender Group Expenses) unless Agent determines that prior notice would
        result in imminent harm to the Collateral or its value), and the Lenders
        with Revolver Commitments thereupon shall, together with Agent, jointly
        determine the terms of arrangements that shall be implemented with
        Borrower intended to reduce, within a reasonable time, the outstanding
        principal amount of the Advances to Borrower to an amount permitted by
        the preceding paragraph. In the event Agent or any Lender disagrees over
        the terms of reduction or repayment of any Overadvance, the terms of
        reduction or repayment thereof shall be implemented according to the
        determination of the Required Lenders.

                                (ii)    Each Lender with a Revolver Commitment
        shall be obligated to settle with Agent as provided in Section 2.3(f)
        for the amount of such Lender's Pro Rata Share of any unintentional
        Overadvances by Agent reported to such Lender, any intentional
        Overadvances made as permitted under this Section 2.3(i), and any
        Overadvances resulting from the charging to the Loan Account of
        interest, fees, or Lender Group Expenses.

                2.4     Payments.

                        (a)     Payments by Borrower.

                                (i)     Except as otherwise expressly provided
        herein, all payments by Borrower shall be made to Agent's Account for
        the account of the Lender Group and shall be made in immediately
        available funds, no later than 11:00 a.m. (California time) on the date
        specified herein. Any payment received by Agent later than



                                      -29-
<PAGE>   36

        11:00 a.m. (California time) shall be deemed to have been received on
        the following Business Day and any applicable interest or fee shall
        continue to accrue until such following Business Day.

                                (ii)    Unless Agent receives notice from
        Borrower prior to the date on which any payment is due to the Lenders
        that Borrower will not make such payment in full as and when required,
        Agent may assume that Borrower has made (or will make) such payment in
        full to Agent on such date in immediately available funds and Agent may
        (but shall not be so required), in reliance upon such assumption,
        distribute to each Lender on such due date an amount equal to the amount
        then due such Lender. If and to the extent Borrower does not make such
        payment in full to Agent on the date when due, each Lender severally
        shall repay to Agent on demand such amount distributed to such Lender,
        together with interest thereon at the Defaulting Lender Rate for each
        day from the date such amount is distributed to such Lender until the
        date repaid.

                        (b)     Apportionment and Application of Payments.

                                (i)     Except as otherwise provided with
        respect to Defaulting Lenders and except as otherwise provided in the
        Loan Documents (including letter agreements between Agent and individual
        Lenders), aggregate principal and interest payments shall be apportioned
        ratably among the Lenders (according to the unpaid principal balance of
        the Obligations to which such payments relate held by each Lender) and
        payments of fees and expenses (other than fees or expenses that are for
        Agent's separate account, after giving effect to any letter agreements
        between Agent and individual Lenders) shall be apportioned ratably among
        the Lenders having a Pro Rata Share of the type of Commitment or
        Obligation to which a particular fee relates. All payments shall be
        remitted to Agent and all such payments not relating to principal or
        interest of specific Obligations (other than payments constituting the
        payment of specific fees), and all proceeds of Accounts or other
        Collateral received by Agent, shall be applied as follows:

                                        (A)     first, to pay any Lender Group
                Expenses then due to Agent under the Loan Documents, until paid
                in full,

                                        (B)     second, to pay any Lender Group
                Expenses then due to the Lenders under the Loan Documents, on a
                ratable basis, until paid in full,

                                        (C)     third, to pay any fees then due
                to Agent (for its separate accounts, after giving effect to any
                letter agreements between Agent and individual Lenders) under
                the Loan Documents until paid in full,

                                        (D)     fourth, to pay any fees then due
                to any or all of the Lenders (after giving effect to any letter
                agreements between Agent and individual Lenders) under the Loan
                Documents, on a ratable basis, until paid in full,



                                      -30-
<PAGE>   37

                                        (E)     fifth, to pay interest due in
                respect of all Agent Advances, until paid in full,

                                        (F)     sixth, ratably to pay interest
                due in respect of the Advances (other than Agent Advances), the
                Swing Loans, and the Term Loan until paid in full,

                                        (G)     seventh, to pay the principal of
                all Agent Advances until paid in full,

                                        (H)     eighth, to pay the principal of
                all Swing Loans until paid in full,

                                        (I)     ninth, ratably (x) to pay the
                principal of all Advances and (y) on the Maturity Date or, at
                the election of the Agent or the Required Lenders (or as
                otherwise provided in a letter agreement among the Agent and the
                Lenders), if an Event of Default has occurred and is continuing,
                to pay the outstanding principal balance of the Term Loan and to
                Agent, to be held by Agent, for the ratable benefit of Issuing
                Lender and those Lenders having a Revolver Commitment, as cash
                collateral in an amount up to 105% of the then extant Letter of
                Credit Usage, in each case until paid in full,

                                        (J)     tenth, to pay any other
                Obligations until paid in full, and

                                        (K)     eleventh, to Borrower (to be
                wired to the Designated Account) or such other Person entitled
                thereto under applicable law.

                                (ii)    Agent promptly shall distribute to each
        Lender, pursuant to the applicable wire instructions received from each
        Lender in writing, such funds as it may be entitled to receive, subject
        to a Settlement delay as provided in Section 2.3(f).

                                (iii)   In each instance, so long as no Event of
        Default has occurred and is continuing, Section 2.4(b) shall not be
        deemed to apply to any payment by Borrower specified by Borrower to be
        for the payment of specific Obligations then due and payable (or
        prepayable) under any provision of this Agreement.

                                (iv)    For purposes of the foregoing, "paid in
        full" means payment of all amounts owing under the Loan Documents
        according to the terms thereof, including loan fees, service fees,
        professional fees, interest, default interest, interest on interest, and
        expense reimbursements.

                                (v)     In the event of a direct conflict
        between the priority provisions of this Section 2.4 and other provisions
        contained in any other Loan Document, it is the intention of the parties
        hereto that such priority provisions in such documents shall be read
        together and construed, to the fullest extent possible, to be in concert
        with each other. In the event of any actual, irreconcilable conflict
        that cannot be

        resolved as aforesaid, the terms and provisions of this Section 2.4
        shall control and govern.

                2.5     Overadvances. If, at any time or for any reason, the
amount of Obligations owed by Borrower to Lender Group pursuant to Sections 2.1
and 2.13 is greater than either the Dollar or percentage limitations set forth
in Sections 2.1 and 2.13, (an "Overadvance"), Borrower immediately shall pay to
Agent, in cash, the amount of such excess, which amount shall be used by Agent
to reduce the Obligations in accordance with the priorities set forth in Section
2.4(b). In addition, Borrower hereby promises to pay the Obligations (including
principal, interest, fees, costs, and expenses) in Dollars in full to the Lender
Group as and when due and payable under the terms of this Agreement and the
other Loan Documents.

                2.6     Interest Rates, Payments, Letter of Credit Fee and
Calculations.

                        (a)     Interest Rates. Except as provided in clause (c)
below, all Obligations (except for undrawn Letters of Credit) that have been
charged to the Loan Account pursuant to the terms hereof (including the portion
of the Obligations consisting of Advances, the Term Loan and the Risk
Participation Liability except for undrawn Letters of Credit) shall bear
interest on the Daily Balance thereof at a per annum rate equal to the Base Rate
plus the Base Rate Margin.

                        (b)     Letter of Credit Fee. Borrower shall pay Agent
(for the ratable benefit of the Lenders with a Revolver Commitment, subject to
any letter agreement between Agent and individual Lenders), a Letter of Credit
fee (in addition to the charges, commissions, fees, and costs set forth in
Section 2.13(e)) which shall accrue at a rate equal to 3.50% per annum times the
Daily Balance of the undrawn amount of all outstanding Letters of Credit.

                        (c)     Default Rate. Upon the occurrence and during the
continuation of an Event of Default (and at the election of Agent or the
Required Lenders), all Obligations (except for undrawn Letters of Credit) that
have been charged to the Loan Account pursuant to the terms hereof shall bear
interest on the Daily Balance thereof at a per annum rate equal to 2 percentage
points above the per annum rate otherwise applicable hereunder, the Letter of
Credit fee provided for above shall be increased to 2 percentage points above
the per annum rate otherwise applicable hereunder.

                        (d)     Payment. Interest, Letter of Credit fees, and
all other fees payable hereunder shall be due and payable, in arrears, on the
first day of each month at any time that Obligations or Commitments are
outstanding. Borrower hereby authorizes Agent, from time to time without prior
notice to Borrower, and the Agent agrees that it will charge such interest and
fees, all Lender Group Expenses (as and when incurred), the charges,
commissions, fees, and costs provided for in Section 2.13(e) (as and when
accrued or incurred), the fees and costs provided for in Section 2.11 (as and
when accrued or incurred) and all other payments as and when due and payable
under any Loan Document (including the amounts due and payable with respect to
the Term Loan) to Borrower's Loan Account, which amounts thereafter constitute
Advances hereunder and shall accrue interest at the rate then applicable to
Advances hereunder. Any interest not paid when due shall be compounded by being
charged to Borrower's Loan



                                      -32-
<PAGE>   39

Account and shall thereafter constitute Advances hereunder and shall accrue
interest at the rate then applicable to Advances.

                        (e)     Computation. All interest and fees chargeable
under the Loan Documents shall be computed on the basis of a 360 day year for
the actual number of days elapsed. In the event the Base Rate is changed from
time to time hereafter, the rates of interest hereunder based upon the Base Rate
automatically and immediately shall be increased or decreased by an amount equal
to such change in the Base Rate.

                        (f)     Intent to Limit Charges to Maximum Lawful Rate.
In no event shall the interest rate or rates payable under this Agreement, plus
any other amounts paid in connection herewith, exceed the highest rate
permissible under any law that a court of competent jurisdiction shall, in a
final determination, deem applicable. Borrower and Lender Group, in executing
and delivering this Agreement, intend legally to agree upon the rate or rates of
interest and manner of payment stated within it; provided, however, that,
anything contained herein to the contrary notwithstanding, if said rate or rates
of interest or manner of payment exceeds the maximum allowable under applicable
law, then, ipso facto, as of the date of this Agreement, Borrower is and shall
be liable only for the payment of such maximum as allowed by law, and payment
received from Borrower in excess of such legal maximum, whenever received, shall
be applied to reduce the principal balance of the Obligations to the extent of
such excess.

                2.7     Cash Management.

                        (a)     Each Loan Party shall on or before the Revolver
Facility Effective Date (i) establish and maintain cash management services of a
type and on terms satisfactory to Agent at one or more of the banks set forth on
Schedule 2.7(a) (each, a "Cash Management Bank"), and shall request in writing
and otherwise take such reasonable steps to ensure that all of its Account
Debtors forward payment of the amounts owed by them directly to such Cash
Management Bank, and (ii) deposit or cause to be deposited promptly, and in any
event no later than the first Business Day after the date of receipt thereof,
all Collections (including those sent directly by Account Debtors to a Cash
Management Bank) into a bank account in Agent's name (a "Cash Management
Account") at one of the Cash Management Banks.

                        (b)     Each Cash Management Bank shall establish and
maintain Cash Management Agreements with Agent and a Loan Party, in form and
substance acceptable to Agent. Each such Cash Management Agreement shall
provide, among other things, that (i) all items of payment deposited in such
Cash Management Account and proceeds thereof are held by such Cash Management
Bank as agent or bailee-in-possession for Agent, (ii) the Cash Management Bank
has no rights of setoff or recoupment or any other claim against the applicable
Cash Management Account other than for payment of its service fees and other
charges directly related to the administration of such Cash Management Account
and for returned checks or other items of payment, and (iii) it immediately will
forward by daily sweep all amounts in the applicable Cash Management Account to
the Agent's Account.

                        (c)     So long as no Default or Event of Default has
occurred and is continuing, the Loan Parties may amend Schedule 2.7(a) to add or
replace a Cash Management Bank or Cash Management Account; provided, however,
that (i) such prospective Cash



                                      -33-
<PAGE>   40

Management Bank shall be satisfactory to Agent and Agent shall have consented in
writing in advance to the opening of such Cash Management Account with the
prospective Cash Management Bank, and (ii) prior to the time of the opening of
such Cash Management Account, the Loan Parties and such prospective Cash
Management Bank shall have executed and delivered to Agent a Cash Management
Agreement. Each Loan Party shall close any of its Cash Management Accounts (and
establish replacement cash management accounts in accordance with the foregoing
sentence) promptly and in any event within 30 days of notice from Agent that the
creditworthiness of any Cash Management Bank is no longer acceptable in Agent's
Permitted Discretion, or as promptly as practicable and in any event within 60
days of notice from Agent that the operating performance, funds transfer, or
availability procedures or performance of the Cash Management Bank with respect
to Cash Management Accounts or Agent's liability under any Cash Management
Agreement with such Cash Management Bank is no longer acceptable in Agent's
Permitted Discretion.

                        (d)     The Cash Management Accounts shall be cash
collateral accounts, with all cash, checks and similar items of payment in such
accounts securing payment of the Obligations, and in which the Loan Parties are
hereby deemed to have granted a Lien to Agent.

                2.8     Crediting Payments; Float Charge.

                        (a)     The receipt of any payment item by Agent
(whether from transfers to Agent by the Cash Management Banks pursuant to the
Cash Management Agreements or otherwise) shall not be considered a payment on
account unless such payment item is a wire transfer of immediately available
federal funds made to the Agent's Account or unless and until such payment item
is honored when presented for payment. Should any payment item not be honored
when presented for payment, then Borrower shall be deemed not to have made such
payment and interest shall be calculated accordingly. Anything to the contrary
contained herein notwithstanding, any payment item shall be deemed received by
Agent only if it is received into the Agent's Account on a Business Day on or
before 11:00 a.m. (California time). If any payment item is received into the
Agent's Account on a non-Business Day or after 11:00 a.m. (California time) on a
Business Day, it shall be deemed to have been received by Agent as of the
opening of business on the immediately following Business Day. All payment items
received by the Agent shall be credited to the Agent's Account for application
on each Business Day as provided above.

                        (b)     From and after the Closing Date, Agent shall be
entitled to charge Borrower for two (2) Business Days of 'clearance' or 'float'
at the rate applicable to Advances under Section 2.6 on all Collections that are
received by a Loan Party (regardless of whether forwarded by the Cash Management
Banks to Agent). This across-the-board two (2) Business Day clearance or float
charge on all Collections is acknowledged by the parties to constitute an
integral aspect of the pricing of the financing of Borrower and shall apply
irrespective of whether or not there are any outstanding monetary Obligations;
the effect of such clearance or float charge being the equivalent of charging
two (2) Business Days of interest on such Collections. The parties acknowledge
and agree that, except as otherwise provided in letter agreements between the
Agent and individual Lenders, the economic benefit of the foregoing provisions
of this Section 2.8 shall be for the exclusive benefit of Agent.



                                      -34-
<PAGE>   41

                2.9     Designated Account. Agent is authorized to make the
Advances and the Term Loan, and Issuing Lender is authorized to issue the
Letters of Credit, under this Agreement based upon telephonic or other
instructions received from anyone purporting to be an Authorized Person, or
without instructions if pursuant to Section 2.6(d). Borrower agrees to establish
and maintain the Designated Account with the Designated Account Bank for the
purpose of receiving the proceeds of the Advances requested by Borrower and made
by Agent or the Lenders hereunder. Unless otherwise agreed by Agent and
Borrower, any Advance, Agent Advance, or Swing Loan requested by Borrower and
made by Agent or the Lenders hereunder shall be made to the Designated Account.

                2.10    Maintenance of Loan Account; Statements of Obligations.
Agent shall maintain an account on its books in the name of Borrower (the "Loan
Account") on which Borrower will be charged with the Term Loan, all Advances
(including Agent Advances and Swing Loans) made by Agent, Swing Lender, or the
Lenders to Borrower or for Borrower's account, the Letters of Credit issued by
Issuing Lender for Borrower's account, and with all other payment Obligations
hereunder or under the other Loan Documents, including, accrued interest, fees
and expenses, and Lender Group Expenses. In accordance with Section 2.8, the
Loan Account will be credited with all payments received by Agent from Borrower
or for Borrower's account, including all amounts received in Agent's Account
from any Cash Management. Agent shall render statements regarding the Loan
Account to Borrower, including principal, interest, fees, and including an
itemization of all charges and expenses constituting Lender Group Expenses
owing, and such statements shall be conclusively presumed to be correct and
accurate and constitute an account stated between Borrower and the Lender Group
unless, within 30 days after receipt thereof by Borrower, Borrower shall deliver
to Agent written objection thereto describing the error or errors contained in
any such statements.

                2.11    Fees. Borrower shall pay to Agent the following fees and
charges, which fees and charges shall be non-refundable when paid (irrespective
of whether this Agreement is terminated thereafter) and shall be apportioned
among the Lenders in accordance with the terms of letter agreements between
Agent and individual Lenders:

                        (a)     Interim Facility Fee. On the Entry Date, a fee
in the amount of $350,000 (the "Interim Facility Fee") which fee shall be earned
in full when paid.

                        (b)     Revolver Facility Fee. On the Revolver Facility
Effective Date, a fee in the amount of $2,200,000 less the amount of the Interim
Facility Fee paid by the Borrower, which fee shall be earned in full when paid.

                        (c)     Unused Line Fee. On the first day of each month
during the term of this Agreement, an unused line fee in an amount equal to .50%
per annum times the result of (a) the Maximum Revolver Amount, less (b) the sum
of (i) the average Daily Balance of Advances that were outstanding during the
immediately preceding month, plus (ii) the average Daily Balance of the Letter
of Credit Usage during the immediately preceding month.

                        (d)     Anniversary Fee. On the first anniversary of the
Entry Date, a fee in the amount of $150,000, which fee shall be earned in full
when paid.



                                      -35-
<PAGE>   42

                        (e)     Audit, Appraisal, and Valuation Charges. For the
separate account of Agent and, in the case of clause (iii) below, the Co-Agent,
audit, appraisal, and valuation fees and charges as follows (i) a fee of $750
per day, per auditor, plus the out-of-pocket expenses for each financial audit
of any Loan Party performed by personnel employed by Agent, (ii) a fee of $1,500
per day per appraiser, plus the out-of-pocket expenses, for each appraisal of
the Collateral performed by personnel employed by Agent, and (iii) the actual
charges paid or incurred by the Agent and the Co-Agent if any such Person elects
to employ the services of one or more third Persons to perform financial audits
of any Loan Party, to appraise the Collateral, or any portion thereof, or to
assess any Loan Party's business valuation.

                        (f)     Servicing Fee. For the sole and separate account
of Agent, on first day of each month during the term of this Agreement, and
thereafter so long as any Obligations are outstanding, a servicing fee in an
amount equal to $10,000, which fee shall be earned in full when paid.

                2.12    Capital Requirements. If, after the date hereof, any
Lender determines that (i) the adoption of or change in any law, rule,
regulation or guideline regarding capital requirements for banks or bank holding
companies, or any change in the interpretation or application thereof by any
Governmental Authority charged with the administration thereof, or (ii)
compliance by such Lender or its parent bank holding company with any guideline,
request, or directive of any such entity regarding capital adequacy (whether or
not having the force of law), the effect of reducing the return on such Lender's
or such holding company's capital as a consequence of such Lender's Commitments
hereunder to a level below that which such Lender or such holding company could
have achieved but for such adoption, change, or compliance (taking into
consideration such Lender's or such holding company's then existing policies
with respect to capital adequacy and assuming the full utilization of such
entity's capital) by any amount deemed by such Lender to be material, then such
Lender may notify Borrower and Agent thereof. Following receipt of such notice,
Borrower agrees to pay such Lender on demand the amount of such reduction of
return of capital as and when such reduction is determined, payable within 90
days after presentation by such Lender of a statement in the amount and setting
forth in reasonable detail such Lender's calculation thereof and the assumptions
upon which such calculation was based (which statement shall be deemed true and
correct absent manifest error). In determining such amount, such Lender may use
any reasonable averaging and attribution methods.

                2.13    Letters of Credit.

                        (a)     Subject to the terms and conditions of this
Agreement and the Orders, on and after the Entry Date the Issuing Lender agrees
to issue letters of credit for the account of Borrower (each, an "L/C") or to
purchase participations or execute indemnities or reimbursement obligations
(each such undertaking, an "L/C Undertaking") with respect to letters of credit
issued by an Underlying Issuer (as of the Closing Date, the prospective
Underlying Issuer is to be Wells Fargo) for the account of Borrower, provided
that, on and after the Closing Date and prior to the Revolver Facility Effective
Date, the Issuing Lender agrees to issue L/Cs or L/C Undertakings, provided
that, prior to the issuance of any such L/C or L/C Undertaking, the Borrower
repays the Advances in an amount equal to the requested L/C or L/C Undertaking.
To request the issuance of an L/C or an L/C Undertaking (or the amendment,
renewal, or extension



                                      -36-
<PAGE>   43

of an outstanding L/C or L/C Undertaking), Borrower shall hand deliver or
telecopy (or transmit by electronic communication, if arrangements for doing so
have been approved by the Issuing Lender) to the Issuing Lender and Agent
(reasonably in advance of the requested date of issuance, amendment, renewal, or
extension) a notice requesting the issuance of an L/C or L/C Undertaking, or
identifying the L/C or L/C Undertaking to be amended, renewed, or extended, the
date of issuance, amendment, renewal, or extension, the date on which such L/C
or L/C Undertaking is to expire, the amount of such L/C or L/C Undertaking, the
name and address of the beneficiary thereof (or the beneficiary of the
Underlying Letter of Credit, as applicable), and such other information as shall
be necessary to prepare, amend, renew, or extend such L/C or L/C Undertaking. If
requested by the Issuing Lender, Borrower also shall be an applicant under the
application with respect to any Underlying Letter of Credit that is to be the
subject of an L/C Undertaking. The Issuing Lender shall have no obligation to
issue a Letter of Credit if any of the following would result after giving
effect to the requested Letter of Credit:

                                (i)     after the Revolver Facility Effective
        Date, the Letter of Credit Usage would exceed the Borrowing Base less
        the amount of outstanding Advances, or

                                (ii)    the Letter of Credit Usage would exceed
        $5,000,000 prior to the Revolver Facility Effective Date and $10,000,000
        thereafter, or

                                (iii)   the Letter of Credit Usage would exceed
        (A) the Maximum Revolver Amount less the then extant amount of
        outstanding Advances or (B) the maximum Indebtedness for the
        corresponding month set forth in Section 7.20(c) less the then extant
        amount of outstanding Advances and the Term Loan.

                Each Letter of Credit (and corresponding Underlying Letter of
Credit) shall have an expiry date no later than 30 days prior to the Maturity
Date and all such Letters of Credit (and corresponding Underlying Letter of
Credit) shall be in form and substance acceptable to the Issuing Lender (in the
exercise of its Permitted Discretion), including the requirement that the
amounts payable thereunder must be payable in Dollars. If Issuing Lender is
obligated to advance funds under a Letter of Credit, Borrower immediately shall
reimburse such L/C Disbursement to Issuing Lender by paying to Agent an amount
equal to such L/C Disbursement not later than 11:00 a.m., California time, on
the date that such L/C Disbursement is made, if Borrower shall have received
written or telephonic notice of such L/C Disbursement prior to 10:00 a.m.,
California time, on such date, or, if such notice has not been received by
Borrower prior to such time on such date, then not later than 11:00 a.m.,
California time, on the Business Day that Borrower receives such notice, if such
notice is received prior to 10:00 a.m., California time, on the date of receipt,
and, in the absence of such reimbursement, the L/C Disbursement immediately and
automatically shall be deemed to be an Advance hereunder and, thereafter, shall
bear interest at the rate then applicable to Advances under Section 2.6. To the
extent an L/C Disbursement is deemed to be an Advance hereunder, Borrower's
obligation to reimburse such L/C Disbursement shall be discharged and replaced
by the resulting Advance. Promptly following receipt by Agent of any payment
from Borrower pursuant to this paragraph, Agent shall distribute such payment to
the Issuing Lender or, to the extent that Lenders have made payments pursuant to
Section 2.13(c) to reimburse the Issuing Lender, then to such Lenders and the
Issuing Lender as their interest may appear.



                                      -37-
<PAGE>   44

                        (b)     Promptly following receipt of a notice of L/C
Disbursement pursuant to Section 2.13(a), each Lender with a Revolver Commitment
agrees to fund its Pro Rata Share of any Advance deemed made pursuant to the
foregoing subsection on the same terms and conditions as if Borrower had
requested such Advance and Agent shall promptly pay to Issuing Lender the
amounts so received by it from the Lenders. By the issuance of a Letter of
Credit (or an amendment to a Letter of Credit increasing the amount thereof) and
without any further action on the part of the Issuing Lender or the Lenders with
Revolver Commitments, the Issuing Lender shall be deemed to have granted to each
Lender with a Revolver Commitment, and each Lender with a Revolver Commitment
shall be deemed to have purchased, a participation in each Letter of Credit, in
an amount equal to its Pro Rata Share of the Risk Participation Liability of
such Letter of Credit, and each such Lender agrees to pay to Agent, for the
account of the Issuing Lender, such Lender's Pro Rata Share of any payments made
by the Issuing Lender under such Letter of Credit. In consideration and in
furtherance of the foregoing, each Lender with a Revolver Commitment hereby
absolutely and unconditionally agrees to pay to Agent, for the account of the
Issuing Lender, such Lender's Pro Rata Share of each L/C Disbursement made by
the Issuing Lender and not reimbursed by Borrower on the date due as provided in
clause (a) of this Section, or of any reimbursement payment required to be
refunded to Borrower for any reason. Each Lender with a Revolver Commitment
acknowledges and agrees that its obligation to deliver to Agent, for the account
of the Issuing Lender, an amount equal to its respective Pro Rata Share pursuant
to this Section 2.13(b) shall be absolute and unconditional and such remittance
shall be made notwithstanding the occurrence or continuation of an Event of
Default or Default or the failure to satisfy any condition set forth in Section
3 hereof. If any such Lender fails to make available to Agent the amount of such
Lender's Pro Rata Share of any payments made by the Issuing Lender in respect of
such Letter of Credit as provided in this Section, Agent (for the account of the
Issuing Lender) shall be entitled to recover such amount on demand from such
Lender together with interest thereon at the Defaulting Lender Rate until paid
in full.

                        (c)     Borrower hereby agrees to indemnify, save,
defend, and hold the Lender Group harmless from any loss, cost, expense, or
liability, and reasonable attorneys fees incurred by the Lender Group arising
out of or in connection with any Letter of Credit; provided, however, that
Borrower shall not be obligated hereunder to indemnify for any loss, cost,
expense, or liability that is caused by the gross negligence or willful
misconduct of the Issuing Lender or any other member of the Lender Group.
Borrower agrees to be bound by the Underlying Issuer's regulations and
interpretations of any Underlying Letter of Credit or by Issuing Lender's
interpretations of any L/C issued by Issuing Lender to or for Borrower's
account, even though this interpretation may be different from Borrower's own,
and Borrower understands and agrees that the Lender Group shall not be liable
for any error, negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letter of Credit or
any modifications, amendments, or supplements thereto. Borrower understands that
the L/C Undertakings may require Issuing Lender to indemnify the Underlying
Issuer for certain costs or liabilities arising out of claims by Borrower
against such Underlying Issuer. Borrower hereby agrees to indemnify, save,
defend, and hold the Lender Group harmless with respect to any loss, cost,
expense (including reasonable attorneys fees), or liability incurred by the
Lender Group under any L/C Undertaking as a result of the Lender Group's
indemnification of any Underlying Issuer; provided, however, that Borrower shall
not be obligated hereunder to



                                      -38-
<PAGE>   45

indemnify for any loss, cost, expense, or liability that is caused by the gross
negligence or willful misconduct of the Issuing Lender or any other member of
the Lender Group.

                        (d)     Borrower hereby authorizes and directs any
Underlying Issuer to deliver to the Issuing Lender all instruments, documents,
and other writings and property received by such Underlying Issuer pursuant to
such Underlying Letter of Credit and to accept and rely upon the Issuing
Lender's instructions with respect to all matters arising in connection with
such Underlying Letter of Credit and the related application.

                        (e)     Any and all charges, commissions, fees, and
costs incurred by the Issuing Lender relating to Underlying Letters of Credit
shall be Lender Group Expenses for purposes of this Agreement and immediately
shall be reimbursable by Borrower to Agent for the account of the Issuing
Lender; it being acknowledged and agreed by Borrower that, as of the Closing
Date, the issuance charge imposed by the prospective Underlying Issuer is .825%
per annum times the face amount of each Underlying Letter of Credit, that such
issuance charge may be changed from time to time, and that the Underlying Issuer
also imposes a schedule of charges for amendments, extensions, drawings, and
renewals.

                        (f)     If by reason of (i) any change in any applicable
law, treaty, rule, or regulation or any change in the interpretation or
application thereof by any Governmental Authority, or (ii) compliance by the
Underlying Issuer or the Lender Group with any direction, request, or
requirement (irrespective of whether having the force of law) of any
Governmental Authority or monetary authority including, Regulation D of the
Federal Reserve Board as from time to time in effect (and any successor
thereto):

                                (i)     any reserve, deposit, or similar
        requirement is or shall be imposed or modified in respect of any Letter
        of Credit issued hereunder, or

                                (ii)    there shall be imposed on the Underlying
        Issuer or the Lender Group any other condition regarding any Underlying
        Letter of Credit or any Letter of Credit issued pursuant hereto,

and the result of the foregoing is to increase, directly or indirectly, the cost
to the Lender Group of issuing, making, guaranteeing, or maintaining any Letter
of Credit or to reduce the amount receivable in respect thereof by the Lender
Group, then, and in any such case, Agent may, at any time within a reasonable
period after the additional cost is incurred or the amount received is reduced,
notify Borrower, and Borrower shall pay on demand such amounts as Agent may
specify to be necessary to compensate the Lender Group for such additional cost
or reduced receipt, together with interest on such amount from the date of such
demand until payment in full thereof at the rate then applicable to Advances.
The determination by Agent of any amount due pursuant to this Section, as set
forth in a certificate setting forth the calculation thereof in reasonable

order of any nature prohibiting, directly or indirectly, the extending of such

written joinder or consent of Agent, on behalf of the Required Lenders, and the

                3.5     Conditions Subsequent to the Initial Extension of
Credit. The obligation of the Lender Group (or any member thereof) to continue
to make Advances (or otherwise extend credit hereunder) is subject to the
fulfillment, on or before the date applicable thereto, of each of the conditions
subsequent set forth below (the failure by Borrower to so perform or cause to be
performed constituting an Event of Default):

                        (a)     within 30 days of the Closing Date, deliver to
Agent certified copies of the policies of insurance, together with the
endorsements thereto, as are required by Section 6.8, the form and substance of
which shall be satisfactory to Agent and its counsel.

                3.6     Term. This Agreement shall become effective upon the
execution and delivery hereof by each Loan Party, each of the Lenders and the
Agent, and shall continue in full force and effect for a term ending on the date
(the "Maturity Date") that is the earliest to occur of (i) the date of
substantial consummation (as defined in Section 1101(2) of the Bankruptcy Code)
of a plan of reorganization in the Chapter 11 Cases that has been confirmed by
order of the Bankruptcy Court, (ii) October 10, 2002, (iii) the conversion of
the Chapter 11 Cases in the Bankruptcy Court to cases under Chapter 7 of the
Bankruptcy Code, (iv) the appointment of a trustee under Chapter 11 of the
Bankruptcy Code, (v) the appointment of an examiner with expanded powers under
the Bankruptcy Code, (vi) the sale of all or substantially all of the assets of
Borrower or ASCI NT, Inc. under Section 363 of the Bankruptcy Code, (vii) the
date which is forty-five (45) days from the Entry Date, if upon that date the
Final Bankruptcy Court Order has



                                      -43-
<PAGE>   50

not been entered; and (viii) the Loan Parties ceasing and discontinuing their
ordinary business operations. The foregoing notwithstanding, the Lender Group,
upon the election of the Required Lenders, shall have the right to terminate its
obligations under this Agreement immediately and without notice to the Borrower
upon the occurrence and during the continuation of an Event of Default.

                3.7     Effect of Termination. On the date of termination of
this Agreement, all Obligations (including contingent reimbursement obligations
of Borrower with respect to outstanding Letters of Credit) immediately shall
become due and payable without notice or demand. No termination of this
Agreement, however, shall relieve or discharge Borrower of its duties,
Obligations, or covenants hereunder and the Agent's Liens in the Collateral
shall remain in effect until all Obligations have been fully and finally
discharged and the Lender Group's obligations to provide additional credit
hereunder have been terminated. When this Agreement has been terminated and all
of the Obligations have been fully and finally discharged and the Lender Group's
obligations to provide additional credit under the Loan Documents have been
terminated irrevocably, Agent will, at Borrower's sole expense, execute and
deliver any lien releases, discharges of security interests, and other similar
discharge or release documents (and, if applicable, in recordable form) as are
reasonably necessary to release, as of record, the Agent's Liens and all notices
of security interests and liens previously filed by Agent with respect to the
Obligations.

                3.8     Early Termination by Borrower. Borrower has the option,
at any time upon 90 days prior written notice to Agent, to terminate this
Agreement by paying to Agent, for the benefit of the Lender Group, in cash, the
Obligations (including either (i) providing cash collateral to be held by Agent
for the benefit of those Lenders with a Revolver Commitment in an amount equal
to 105% of the then extant Letter of Credit Usage, or (ii) causing the original
Letters of Credit to be returned to the Issuing Lender), in full, together with
the Applicable Prepayment Premium (to be allocated based upon letter agreements
between Agent and individual Lenders). If Borrower has sent a notice of
termination pursuant to the provisions of this Section, then the Commitments
shall terminate and Borrower shall be obligated to repay the Obligations
(including either (i) providing cash collateral to be held by Agent for the
benefit of those Lenders with a Revolver Commitment in an amount equal to 105%
of the then extant Letter of Credit Usage, or (ii) causing the original Letters
of Credit to be returned to the Issuing Lender), in full, together with the
Applicable Prepayment Premium, on the date set forth as the date of termination
of this Agreement in such notice. In the event of the termination of this
Agreement and repayment of the Obligations at any time prior to the Maturity
Date, for any other reason, including (a) termination upon the election of the
Required Lenders to terminate after the occurrence of an Event of Default, (b)
foreclosure and sale of Collateral or (c) by the confirmation of a plan of
reorganization in the Chapter 11 cases, then, in view of the impracticability
and extreme difficulty of ascertaining the actual amount of damages to the
Lender Group or profits lost by Lender Group as a result of such early
termination, and by mutual agreement of the parties as to a reasonable
estimation and calculation of the lost profits or damages of the Lender Group,
Borrower shall pay the Applicable Prepayment Premium to Agent (to be allocated
based upon letter agreements between Agent and individual Lenders), measured as
of the date of such termination.

                4.      CREATION OF SECURITY INTEREST.

                4.1     Grant of Security Interest. Each Loan Party hereby
grants to Agent, for the benefit of the Lender Group, a continuing security
interest in all of its right, title, and interest in all currently existing and
hereafter acquired or arising Collateral in order to secure prompt repayment of
any and all of the Obligations in accordance with the terms and conditions of
the Loan Documents and in order to secure prompt performance by each Loan Party
of each of their covenants and duties under the Loan Documents. The Agent's
Liens in and to the Collateral shall attach to all Collateral without further
act on the part of Agent or any Loan Party. Anything contained in this Agreement
or any other Loan Document to the contrary notwithstanding, except for Permitted
Dispositions, no Loan Party has authority, express or implied, to dispose of any
item or portion of the Collateral.

                4.2     Negotiable Collateral. In the event that any Collateral,
including proceeds, is evidenced by or consists of Negotiable Collateral, and if
and to the extent that perfection or priority of Agent's security interest is
dependent on or enhanced by possession, each Loan Party, immediately upon the
request of Agent, shall endorse and deliver physical possession of such
Negotiable Collateral to Agent.

                4.3     Collection of Accounts, General Intangibles, and
Negotiable Collateral. At any time after the occurrence and during the
continuation of an Event of Default, Agent or Agent's designee may (a) notify
Account Debtors of each Loan Party that the Accounts, chattel paper, or General
Intangibles have been assigned to Agent or that Agent has a security interest
therein, or (b) collect the Accounts, chattel paper, or General Intangibles
directly and charge the collection costs and expenses to the Loan Account. Each
Loan Party agrees that it will hold in trust for the Lender Group, as the Lender
Group's trustee, any Collections that it receives and immediately will deliver
said Collections to Agent or a Cash Management Bank in their original form as
received by such Loan Party.

                4.4     Delivery of Additional Documentation Required. At any
time upon the request of Agent, each Loan Party shall execute and deliver to
Agent, any and all financing statements, original financing statements in lieu
of continuation statements, fixture filings, security agreements, pledges,
assignments, endorsements of certificates of title, and all other documents (the
"Additional Documents") that Agent may request in its Permitted Discretion, in
form and substance satisfactory to Agent, to perfect and continue perfected the
Agent's Liens in the Collateral (whether now owned or hereafter arising or
acquired), to create and perfect Liens in favor of Agent in any Real Property
Collateral acquired after the Closing Date, and in order to fully consummate all
of the transactions contemplated hereby and under the other Loan Documents. To
the maximum extent permitted by applicable law, each Loan Party authorizes Agent
to execute any such Additional Documents in such Loan Party's name and
authorizes Agent to file such executed Additional Documents in any appropriate
filing office. In addition, on such periodic basis as Agent shall require, each
Loan Party shall (a) provide Agent with a report of all new material patentable,
copyrightable, or trademarkable materials acquired or generated by such Loan
Party during the prior period, (b) cause all material patents, copyrights, and
trademarks acquired or generated by such Loan Party that are not already the
subject of a registration with the appropriate filing office (or an application
therefor diligently prosecuted) to be registered with such appropriate filing
office in a manner sufficient to impart constructive



                                      -45-
<PAGE>   52

notice of such Loan Party's ownership thereof, and (c) cause to be prepared,
executed, and delivered to Agent supplemental schedules to the applicable Loan
Documents to identify such patents, copyrights, and trademarks as being subject
to the security interests created thereunder.

                4.5     Power of Attorney. Each Loan Party hereby irrevocably
makes, constitutes, and appoints Agent (and any of Agent's officers, employees,
or agents designated by Agent) as such Loan Party's true and lawful attorney,
with power to (a) if such Loan Party refuses to, or fails timely to execute and
deliver any of the documents described in Section 4.4, sign the name of such
Loan Party on any of the documents described in Section 4.4, (b) at any time
that an Event of Default has occurred and is continuing, sign such Loan Party's
name on any invoice or bill of lading relating to the Collateral, drafts against
Account Debtors, or notices to Account Debtors, (c) send requests for
verification of Accounts, (d) endorse such Loan Party's name on any Collection
item that may come into the Lender Group's possession, (e) at any time that an
Event of Default has occurred and is continuing, make, settle, and adjust all
claims under such Loan Party's policies of insurance and make all determinations
and decisions with respect to such policies of insurance, and (f) at any time
that an Event of Default has occurred and is continuing, settle and adjust
disputes and claims respecting the Accounts, chattel paper, or General
Intangibles directly with Account Debtors, for amounts and upon terms that Agent
determines to be reasonable, and Agent may cause to be executed and delivered
any documents and releases that Agent determines to be necessary. The
appointment of Agent as each Loan Party's attorney, and each and every one of
its rights and powers, being coupled with an interest, is irrevocable until all
of the Obligations have been fully and finally repaid and performed and the
Lender Group's obligations to extend credit hereunder are terminated.

                4.6     Right to Inspect. Agent and each Lender (through any of
their respective officers, employees, or agents) shall have the right, from time
to time hereafter to inspect the Books and to check, test, and appraise the
Collateral in order to verify each Loan Party's financial condition or the
amount, quality, value, condition of, or any other matter relating to, the
Collateral and such inspection, appraisal and verification shall be conducted in
a manner so as not to unreasonably disrupt the business of any Loan Party,
provided that, in the absence of a continuing Event of Default (i) the Borrower
shall not be obligated to pay for more than two (2) such inspections, appraisals
and verifications in any calendar year, (ii) the first such inspection,
appraisal and verification shall not occur until on or after the date that is
three (3) months after the Revolver Facility Effective Date, and (iii) the
Borrower will receive reasonable prior notice of any such inspection, appraisal
or verification.

                4.7     Administrative Priority. Each Loan Party hereby agrees
that the Obligations shall constitute allowed administrative expenses in the
Chapter 11 Cases having priority over all administrative expenses of and
unsecured claims against such Loan Party now existing or hereafter arising, of
any kind or nature whatsoever, including without limitation all administrative
expenses of the kind specified in Sections 503(b) and 507(b) of the Bankruptcy
Code, subject, as to priority, only to the Carve-Out Expenses having priority
over any Obligations to the extent set forth in the definition of Agreed
Administrative Expense Priorities.

                4.8     Grants, Rights and Remedies. The Liens and security
interests granted by each Loan Party to Agent (for the benefit of Lender Group)
by and pursuant to Section 4.1 hereof and administrative priority granted by and
pursuant to Section 4.7 hereof may be independently



                                      -46-
<PAGE>   53

granted by the Loan Documents hereafter entered into. This Agreement, the
Interim Bankruptcy Court Order, the Final Bankruptcy Court Order and such other
Loan Documents supplement each other, and the grants, priorities, rights and
remedies of Agent hereunder and thereunder are cumulative.

                4.9     No Filings Required. The Liens and security interests
granted by each Loan Party to Agent (for the benefit of Lender Group) herein
shall be deemed valid, binding, continuing, enforceable and fully-perfected
first priority Liens on the Collateral by entry of the Interim Bankruptcy Court
Order and the Final Bankruptcy Court Order, as the case may be subject to
Permitted Priority Liens. Agent shall not be required to file any financing
statements, notices of Lien or similar instruments in any jurisdiction or filing
office or to take any other action in order to validate or perfect the Liens and
security interests granted by or pursuant to this Agreement, the Interim
Bankruptcy Court Order, the Final Bankruptcy Court Order or any other Loan
Document.

                4.10    Survival. The Liens and security interests granted to
Agent (for the benefit of Lender Group), the priority of such Liens and security
interests, and the administrative priorities and other rights and remedies
granted to Lender Group pursuant to this Agreement, the Interim Bankruptcy Court
Order, the Final Bankruptcy Court Order and the other Loan Documents
(specifically including but not limited to the existence, perfection and
priority of the Liens and security interest provided herein and therein) and the
administrative priority provided herein and therein shall not be modified,
altered or impaired in any manner by any other financing or extension of credit
or incurrence of debt by any Loan Party (pursuant to Section 364 of the
Bankruptcy Code or otherwise), or by any dismissal or conversion of the Chapter
11 Cases, or by any other act or omission whatsoever. Without limitation,
notwithstanding any such order, financing, extension, incurrence, dismissal,
conversion, act or omission;

                        (a)     except for the Carve-Out Expenses having a
priority over the Obligations to the extent set forth in the definition of
Agreed Administrative Expense Priorities, no costs or expenses of administration
which have been or may be incurred in the Chapter 11 Cases or any conversion of
the same or in any other proceedings related thereto, and no priority claims,
are or will be prior to or on a parity with any claim of Agent and Lenders
against any Loan Party in respect of any Obligation;

                        (b)     the Liens and security interests granted by each
Loan Party to Agent (for the benefit of Lender Group) by and pursuant to the
Interim Bankruptcy Court Order, the Final Bankruptcy Court Order and Section 4.1
hereof shall constitute valid, binding, continuing, enforceable and
fully-perfected first priority Liens, subject only to Permitted Priority Liens
to which such Liens and security interests shall or may be subordinate and
junior, and shall be prior to all other Liens and interests, now existing or
hereafter arising, in favor of any other creditor or any other Person
whatsoever; and

                        (c)     the Liens and security interests granted by each
Loan Party to Agent (for the benefit of Lender Group) by and pursuant to the
Interim Bankruptcy Court Order, the Final Bankruptcy Court Order and Section 4.1
hereof shall continue to be valid, binding, continuing, enforceable and
fully-perfected without the necessity for Agent to file any financing statements
or to otherwise perfect such Liens and security interests under applicable
non-bankruptcy law.

<PAGE>   54

                4.11    Control Agreements. Each Loan Party agrees that it will
not transfer assets out of any Securities Accounts other than as permitted under
Section 7.19 and, if to another securities intermediary, unless each of such
Loan Party, Agent, and the substitute securities intermediary have entered into
a Control Agreement. No arrangement contemplated hereby or by any Control
Agreement in respect of any Securities Accounts or other Investment Property
shall be modified by any Loan Party without the prior written consent of Agent.
Upon the occurrence and during the continuance of an Event of Default, Agent may
notify any securities intermediary to liquidate the applicable Securities

their expiration dates, held by each of the Loan Parties as of the date of this

in a Material Adverse Change. None of the Loan Parties is a party as a defendant
to, or is aware of any overt threat of, any litigation, proceedings, action,
notice of violation or apparent liability, order to show cause, order of
forfeiture, formal or informal complaint, inquiry or investigation by or before
the FCC, any State PUC or any local governmental authority with jurisdiction
over the services which it offers as to which there is a reasonable possibility
of an adverse determination and, which if adversely determined, could reasonably
be expected, individually or in the aggregate, to result in a Material Adverse
Change.

regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940 or
under any other federal or state statute or regulation (other than Regulation X
of the Board of Governors of the Federal Reserve System) which may limit its
ability to incur Indebtedness or which may otherwise render all or any portion
of the Obligations unenforceable.

Permitted Discretion, materially impair the prospects of repayment of the
Obligations by the Loan Parties or materially impair the Loan Parties'
creditworthiness, (ii) such refinancings, renewals, or extensions do not result
in an increase in the principal amount of, or interest rate with respect to, the

                8.      EVENTS OF DEFAULT.

provision, condition, covenant, or agreement contained in this Agreement or in
any of the other Loan Documents;

entered by the Bankruptcy Court without the express prior written consent of
Agent, (i) to revoke, vacate, reverse, stay, modify, supplement or amend this

Expense Priorities;

                8.10    An order shall be entered by the Bankruptcy Court
granting relief from the automatic stay to any creditor(s) of any Loan Party
with respect to any claim in an amount equal to or exceeding $750,000 in the
aggregate; provided, however, that it shall not be an Event of Default if relief

collect solely against an insurance company;

                8.11    An application for any of the orders described in

interest created by this Agreement, the Interim Bankruptcy Court Order or the
Final Bankruptcy Court Order shall, for any reason, cease to be valid or (c) any

interests of Agent created by this Agreement, the Interim Bankruptcy Court Order
or the Final Bankruptcy Court Order;

                8.13    If any Loan Party is enjoined, restrained, or in any way
prevented by court order from continuing to conduct all or any material part of
its business affairs;

                8.14    If a Lien, levy, or assessment is filed of record with
respect to any of the Loan Parties' assets by the United States, or any
department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, or if any taxes or debts owing at any



                                      -68-
<PAGE>   75

time hereafter to any one or more of such entities becomes a Lien, whether
choate or otherwise, upon any of the Loan Parties' assets and the same is not
paid before such payment is delinquent;

                8.15    If there is a default in any material agreement to which
any Loan Party is a party and such default results in a right by the other party
thereto, which is not stayed by reason of the commencement of the Chapter 11
Cases and irrespective of whether exercised, to accelerate the maturity of any
Loan Party's obligations thereunder, to terminate such agreement, or to refuse
to renew such agreement pursuant to an automatic renewal right therein;

                8.16    If any Loan Party makes any payment on account of
Indebtedness that has been contractually subordinated in right of payment to the
payment of the Obligations, except to the extent such payment is permitted by
the terms of the subordination provisions applicable to such Indebtedness;

                8.17    If any material misstatement or misrepresentation exists
now or hereafter in any warranty, representation, statement, or Record made to
the Lender Group by any Loan Party, or any officer, employee, agent, or director
of any Loan Party;

                8.18    If this Agreement or any other Loan Document that
purports to create a Lien, shall, for any reason, fail or cease to create a
valid and perfected and, except to the extent permitted by the terms hereof or
thereof, first priority Lien on or security interest in the Collateral covered
hereby or thereby;

                8.19    Any provision of any Loan Document shall at any time for
any reason be declared to be null and void, or the validity or enforceability
thereof shall be contested by any Loan Party, or a proceeding shall be commenced
by any Loan Party, or by any Governmental Authority having jurisdiction over any
Loan Party, seeking to establish the invalidity or unenforceability thereof, or
any Loan Party shall deny that such Loan Party has any liability or obligation
purported to be created under any Loan Document;

                8.20    Any of the following shall occur, the result of which

materially impaired or otherwise finally denied renewal, or shall cease to be in
full force and effect; (ii) any proceeding shall have been instituted by or
shall have been commenced before any court or any Communications Regulatory

termination, rescission, revocation, material impairment, suspension or denial
of renewal of a material License, or (b) a modification of a material License in
a material adverse respect or a renewal thereof on terms that materially and
adversely affect the economic or commercial value or usefulness thereof; or

suspended or otherwise materially impaired, or shall be renegotiated and renewed
or replaced on terms that materially and adversely affect the economic or
commercial value or usefulness thereof, whether by action of the parties thereto
or by action of or under, modification to, or rescinding of the Communications
Act, State Law or any Regulations, in whole or in part; or

                8.21    The Loan Parties shall have defaulted in any of their
obligations under the Adequate Protection Stipulation.

                9.      THE LENDER GROUP'S RIGHTS AND REMEDIES.

                9.1     Rights and Remedies. Notwithstanding the provisions of
Section 362 of the Bankruptcy Code, upon the occurrence, and during the
continuation, of an Event of Default, Agent may, and shall at the authorization
and instruction of the Required Lenders (at their election but without notice of
their election and without demand) do any one or more of the following on behalf
of the Lender Group, all of which are authorized by the Loan Parties:

                        (a)     Declare all Obligations, whether evidenced by
this Agreement, by any of the other Loan Documents, or otherwise, immediately
due and payable;

                        (b)     Cease advancing money or extending credit to or
for the benefit of Borrower under this Agreement, under any of the Loan
Documents, or under any other agreement between Borrower and the Lender Group;

                        (c)     Terminate this Agreement and any of the other
Loan Documents as to any future liability or obligation of the Lender Group, but
without affecting any of the Agent's Liens in the Collateral and without
affecting the Obligations;

                        (d)     Settle or adjust disputes and claims directly
with Account Debtors for amounts and upon terms which Agent considers advisable,
and in such cases, Agent will credit Borrower's Loan Account with only the net
amounts received by Agent in payment of such disputed Accounts after deducting
all Lender Group Expenses incurred or expended in connection therewith;

                        (e)     Cause each Loan Party to hold all returned
Inventory in trust for the Lender Group, segregate all returned Inventory from
all other assets of each Loan Party or in each Loan Party's possession and
conspicuously label said returned Inventory as the property of the Lender Group;

                        (f)     Without notice to or demand upon any Loan Party,
make such payments and do such acts as Agent considers necessary or reasonable
to protect its security interests in the Collateral. Each Loan Party agrees to
assemble the Personal Property Collateral if Agent so requires, and to make the
Personal Property Collateral available to Agent at a place that Agent may
designate which is reasonably convenient to both parties. Each Loan Party
authorizes Agent to enter the premises where the Personal Property Collateral is
located, to take and maintain possession of the Personal Property Collateral, or
any part of it, and to pay, purchase, contest, or compromise any Lien that in
Agent's determination appears to conflict with the Agent's Liens and to pay all
expenses incurred in connection therewith and to charge Borrower's Loan Account
therefor. With respect to any Loan Party's owned or leased premises, each Loan
Party hereby grants Agent a license to enter into possession of such premises
and to occupy the same, without charge, in order to exercise any of Lender
Group's rights or remedies provided herein, at law, in equity, or otherwise;

                        (g)     Without notice to any Loan Party (such notice
being expressly waived), and without constituting a retention of any collateral
in satisfaction of an obligation (within the meaning of the Code), set off and
apply to the Obligations any and all (i) balances and deposits of any Loan Party
held by the Lender Group (including any amounts received in the



                                      -70-
<PAGE>   77


Cash Management Accounts), or (ii) Indebtedness at any time owing to or for the
credit or the account of any Loan Party held by the Lender Group;

                        (h)     Hold, as cash collateral, any and all balances
and deposits of each Loan Party held by the Lender Group, and any amounts
received in the Cash Management Accounts, to secure the full and final repayment
of all of the Obligations;

                        (i)     Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Personal Property Collateral. Each Loan Party hereby grants to
Agent a license or other right to use, without charge, such Loan Party's labels,
patents, copyrights, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the
Personal Property Collateral, in completing production of, advertising for sale,
and selling any Personal Property Collateral and such Loan Party's rights under
all licenses and all franchise agreements shall inure to the Lender Group's
benefit;

                        (j)     Sell the Personal Property Collateral at either
a public or private sale, or both, by way of one or more contracts or
transactions, for cash or on terms, in such manner and at such places (including
any Loan Party's premises) as Agent determines is commercially reasonable. It is
not necessary that the Personal Property Collateral be present at any such sale;

                        (k)     Except as otherwise provided in the Orders or in
any other order of the Bankruptcy Court in the Chapter 11 Cases, Agent shall
give notice of the disposition of the Collateral as follows:

                                (i)     Agent shall give Borrower a notice in
        writing of the time and place of public sale, or, if the sale is a
        private sale or some other disposition other than a public sale is to be
        made of the Collateral, the time on or after which the private sale or
        other disposition is to be made; and

                                (ii)    The notice shall be personally delivered
        or mailed, postage prepaid, to Borrower as provided in Section 12, at
        least 10 days before the earliest time of disposition set forth in the
        notice; no notice needs to be given prior to the disposition of any
        portion of the Collateral that is perishable or threatens to decline
        speedily in value or that is of a type customarily sold on a recognized
        market;

                        (l)     Agent, on behalf of the Lender Group, may credit
bid and purchase at any public sale; and

                        (m)     Agent may seek the appointment of a receiver or
keeper to take possession of all or any portion of the Collateral or to operate
same and, to the maximum extent permitted by law, may seek the appointment of
such a receiver without the requirement of prior notice or a hearing;

                        (n)     The Lender Group shall have all other rights and
remedies available at law or in equity or pursuant to any other Loan Document;
and



                                      -71-
<PAGE>   78


                        (o)     Any deficiency that exists after disposition of
the Collateral as provided above will be paid immediately by the Loan Parties.
Any excess will be returned, without interest and subject to the rights of third
Persons, by Agent to Borrower.

                9.2     Remedies Cumulative. The rights and remedies of the
Lender Group under this Agreement, the other Loan Documents, and all other
agreements shall be cumulative. The Lender Group shall have all other rights and
remedies not inconsistent herewith as provided under the Code, by law, or in
equity. No exercise by the Lender Group of one right or remedy shall be deemed
an election, and no waiver by the Lender Group of any Event of Default shall be
deemed a continuing waiver. No delay by the Lender Group shall constitute a
waiver, election, or acquiescence by it.

                10.     TAXES AND EXPENSES.

                If any Loan Party fails to pay any monies (whether taxes,
assessments, insurance premiums, or, in the case of leased properties or assets,
rents or other amounts payable under such leases) due to third Persons, or fails
to make any deposits or furnish any required proof of payment or deposit, all as
required under the terms of this Agreement, then, Agent, in its sole discretion
and without prior notice to any Loan Party, may do any or all of the following:
(a) make payment of the same or any part thereof, (b) set up such reserves in
Borrower's Loan Account as Agent deems necessary to protect the Lender Group
from the exposure created by such failure, or (c) in the case of the failure to
comply with Section 6.8 hereof, obtain and maintain insurance policies of the
type described in Section 6.8 and take any action with respect to such policies
as Agent deems prudent. Any such amounts paid by Agent shall constitute Lender
Group Expenses and any such payments shall not constitute an agreement by the
Lender Group to make similar payments in the future or a waiver by the Lender
Group of any Event of Default under this Agreement. Agent need not inquire as
to, or contest the validity of, any such expense, tax, or Lien and the receipt
of the usual official notice for the payment thereof shall be conclusive
evidence that the same was validly due and owing.

                11.     WAIVERS; INDEMNIFICATION.

                11.1    Demand; Protest; etc. Each Loan Party waives demand,
protest, notice of protest, notice of default or dishonor, notice of payment and
nonpayment, nonpayment at maturity, release, compromise, settlement, extension,
or renewal of documents, instruments, chattel paper, and guarantees at any time
held by the Lender Group on which any Loan Party may in any way be liable.

                11.2    The Lender Group's Liability for Collateral. Each Loan
Party hereby agrees that: (a) so long as Agent complies with its obligations, if
any, under the Code, the Lender Group shall not in any way or manner be liable
or responsible for: (i) the safekeeping of the Collateral, (ii) any loss or
damage thereto occurring or arising in any manner or fashion from any cause,
(iii) any diminution in the value thereof, or (iv) any act or default of any
carrier, warehouseman, bailee, forwarding agency, or other Person, and (b) all
risk of loss, damage, or destruction of the Collateral shall be borne by the
Loan Parties.

<PAGE>   79


                11.3    Indemnification. Each Loan Party shall pay, indemnify,
defend, and hold the Agent-Related Persons, the Lender-Related Persons with
respect to each Lender, each Participant, and each of their respective officers,
directors, employees, agents, and attorneys-in-fact (each, an "Indemnified
Person") harmless (to the fullest extent permitted by law) from and against any
and all claims, demands, suits, actions, investigations, proceedings, and
damages, and all reasonable attorneys fees and disbursements and other costs and
expenses actually incurred in connection therewith (as and when they are
incurred and irrespective of whether suit is brought), at any time asserted
against, imposed upon, or incurred by any of them (a) in connection with or as a
result of or related to the execution, delivery, enforcement, performance, or
administration of this Agreement, any of the other Loan Documents, or the
transactions contemplated hereby or thereby, and (b) with respect to any
investigation, litigation, or proceeding related to this Agreement, any other
Loan Document, or the use of the proceeds of the credit provided hereunder
(irrespective of whether any Indemnified Person is a party thereto), or any act,
omission, event, or circumstance in any manner related thereto (all the
foregoing, collectively, the "Indemnified Liabilities"). The foregoing to the
contrary notwithstanding, each Loan Party shall have no obligation to any
Indemnified Person under this Section 11.3 with respect to any Indemnified
Liability that a court of competent jurisdiction finally determines to have
resulted from the gross negligence or willful misconduct of such Indemnified
Person. This provision shall survive the termination of this Agreement and the
repayment of the Obligations. If any Indemnified Person makes any payment to any
other Indemnified Person with respect to an Indemnified Liability as to which
Borrower was required to indemnify the Indemnified Person receiving such
payment, the Indemnified Person making such payment is entitled to be
indemnified and reimbursed by Borrower with respect thereto. WITHOUT LIMITATION,
THE FOREGOING INDEMNITY SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO
INDEMNIFIED LIABILITIES WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF
ANY NEGLIGENT ACT OR OMISSION OF SUCH INDEMNIFIED PERSON OR OF ANY OTHER PERSON.

                12.     NOTICES.

                Unless otherwise provided in this Agreement, all notices or
demands by Borrower or Agent to the other relating to this Agreement or any
other Loan Document shall be in writing and (except for financial statements and
other informational documents which may be sent by first-class mail, postage
prepaid) shall be personally delivered or sent by registered or certified mail

earlier of the date of actual receipt or 3 Business Days after the deposit
thereof in the mail. Borrower acknowledges and agrees that notices sent by the
Lender Group in connection with the exercise of enforcement rights against
Collateral under the provisions of the Code shall be deemed sent when deposited
in the mail or personally delivered, or, where permitted by law, transmitted by
telefacsimile or any other method set forth above.

                13.     CHOICE OF LAW; JURY TRIAL WAIVER.

                        (a)     THE VALIDITY OF THIS AGREEMENT AND THE OTHER
LOAN DOCUMENTS (UNLESS EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER LOAN
DOCUMENT IN RESPECT OF SUCH OTHER LOAN DOCUMENT), THE CONSTRUCTION,
INTERPRETATION, AND ENFORCEMENT HEREOF AND THEREOF, AND THE RIGHTS OF THE
PARTIES HERETO AND THERETO WITH RESPECT TO ALL MATTERS ARISING HEREUNDER OR
THEREUNDER OR RELATED HERETO OR THERETO SHALL BE DETERMINED UNDER, GOVERNED BY,

<PAGE>   81


                        (b)     EACH LOAN PARTY AND THE LENDER GROUP HEREBY
WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH LOAN
PARTY AND THE LENDER GROUP REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH
KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION
WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS AGREEMENT MAY BE
FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

                14.     ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS.

                14.1    Assignments and Participations.

                        (a)     Any Lender may, with the written consent of
Agent (provided that no written consent of Agent shall be required in connection
with any assignment and delegation by a Lender to an Eligible Transferee and no
notice to Agent shall be required in connection with any assignment and
delegation by a Lender to an Affiliate of a Lender or a fund or account managed
by a Lender or an Affiliate of a Lender), assign and delegate to one or more
assignees (each an "Assignee") all, or any ratable part of all, of the
Obligations, the Commitments and the other rights and obligations of such Lender
hereunder and under the other Loan Documents, in a minimum amount of $5,000,000
(except such minimum amount shall not apply to any Affiliate of a Lender or to a
fund or account managed by a Lender, provided that if the minimum amount is not
met, Borrower and Agent may continue to deal solely and directly with such
Lender in connection with the interest so assigned to an Assignee); provided,
however, that Borrower and Agent may continue to deal solely and directly with
such Lender in connection with the interest so assigned to an Assignee until (i)
written notice of such assignment, together with payment instructions,
addresses, and related information with respect to the Assignee, have been given
to Borrower and Agent by such Lender and the Assignee, (ii) such Lender and its
Assignee have delivered to Borrower and Agent a fully-executed Assignment and
Acceptance substantially in the form of Exhibit A-1, and (iii) the assignor
Lender or Assignee has paid to Agent for Agent's separate account a processing
fee in the amount of $5,000. Anything contained herein to the contrary
notwithstanding, the consent of Agent shall not be required (and payment of any
fees shall not be required) if such assignment is in connection with any merger,
consolidation, sale, transfer, or other disposition of all or any substantial
portion of the business or loan portfolio of such Lender or the assignee is an
Affiliate (other than individuals) of, or a fund, money market account,
investment account or other account managed by a Lender or an Affiliate of a
Lender.

                        (b)     From and after the date that Agent notifies the
assignor Lender (with a copy to Borrower), if applicable, that it has received a
fully-executed Assignment and Acceptance and payment (if applicable) of the
above-referenced processing fee, (i) the Assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, shall have the rights
and obligations of a Lender under the Loan Documents, and (ii) the assignor
Lender shall, to the extent that rights and obligations hereunder and under the
other Loan Documents have been



                                      -75-
<PAGE>   82


assigned by it pursuant to such Assignment and Acceptance, relinquish its rights
(except with respect to Section 11.3 hereof) and be released from its
obligations under this Agreement (and in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement and the other Loan Documents, such Lender
shall cease to be a party hereto and thereto), and such assignment shall affect
a novation between Borrower and the Assignee.

                        (c)     By executing and delivering an Assignment and
Acceptance, the assigning Lender thereunder and the Assignee thereunder confirm
to and agree with each other and the other parties hereto as follows: (1) other
than as provided in such Assignment and Acceptance, such assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other Loan Document furnished
pursuant hereto, (2) such assigning Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of any
Loan Party or the performance or observance by any Loan Party of any of its
obligations under this Agreement or any other Loan Document furnished pursuant
hereto, (3) such Assignee confirms that it has received a copy of this
Agreement, together with such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance, (4) such Assignee will, independently and without
reliance upon Agent, such assigning Lender or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement, (5) such Assignee appoints and authorizes Agent to take such
actions and to exercise such powers under this Agreement as are delegated to
Agent, by the terms hereof, together with such powers as are reasonably
incidental thereto, and (6) such Assignee agrees that it will perform all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

                        (d)     Immediately upon each Assignee's making its
processing fee payment (if applicable) under the Assignment and Acceptance and
receipt and acknowledgment by Agent of such fully executed Assignment and
Acceptance, this Agreement shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The Commitment
allocated to each Assignee shall reduce such Commitments of the assigning Lender
pro tanto.

                        (e)     Any Lender may at any time, sell to one or more
commercial banks, financial institutions, or other Persons not Affiliates of
such Lender (a "Participant") participating interests in its Obligations, the
Commitment, and the other rights and interests of that Lender (the "Originating
Lender") hereunder and under the other Loan Documents (provided that no written
consent of Agent shall be required in connection with any sale of any such
participating interests by a Lender to an Eligible Transferee); provided,
however, that (i) the Originating Lender shall remain a "Lender" for all
purposes of this Agreement and the other Loan Documents and the Participant
receiving the participating interest in the Obligations, the Commitments, and
the other rights and interests of the Originating Lender hereunder shall not
constitute a "Lender" hereunder or under the other Loan Documents and the
Originating Lender's obligations under this Agreement shall remain unchanged,
(ii) the Originating Lender shall



                                      -76-
<PAGE>   83


remain solely responsible for the performance of such obligations, (iii)
Borrower, Agent, and the Lenders shall continue to deal solely and directly with
the Originating Lender in connection with the Originating Lender's rights and
obligations under this Agreement and the other Loan Documents, (iv) no Lender
shall transfer or grant any participating interest under which the Participant
has the right to approve any amendment to, or any consent or waiver with respect
to, this Agreement or any other Loan Document, except to the extent such
amendment to, or consent or waiver with respect to this Agreement or of any
other Loan Document would (A) extend the final maturity date of the Obligations
hereunder in which such Participant is participating, (B) reduce the interest
rate applicable to the Obligations hereunder in which such Participant is
participating, (C) release all or a material portion of the Collateral or
guaranties (except to the extent expressly provided herein or in any of the Loan
Documents) supporting the Obligations hereunder in which such Participant is
participating, (D) postpone the payment of, or reduce the amount of, the
interest or fees payable to such Participant, or (E) change the amount or due
dates of scheduled principal repayments or prepayments or premiums in respect of
the Obligations hereunder in which such Participant is participating, or (F)
subordinates the Lien of the Agent for the benefit of the Lender Group to the
Liens of any other creditor of the Loan Parties, and (v) all amounts payable by
Borrower hereunder shall be determined as if such Lender had not sold such
participation, except that, if amounts outstanding under this Agreement are due
and unpaid, or shall have been declared or shall have become due and payable
upon the occurrence of an Event of Default, each Participant shall be deemed to
have the right of set-off in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as Lender under this Agreement,
provided that a Participant shall only have such right of set-off if the
Borrower has received prior written notice of such Participant. The rights of
any Participant only shall be derivative through the Originating Lender with
whom such Participant participates and no Participant shall have any rights
under this Agreement or the other Loan Documents or any direct rights as to the
other Lenders, Agent, Borrower, the Collections, the Collateral, or otherwise in
respect of the Obligations. No Participant shall have the right to participate
directly in the making of decisions by the Lenders among themselves. The
provisions of this Section 14(e) are solely for the benefit of the Lender Group,
and none of the Loan Parties shall have any rights as a third party beneficiary
of any such provisions.

                        (f)     In connection with any such assignment or
participation or proposed assignment or participation, a Lender may disclose all
documents and information which it now or hereafter may have relating to
Borrower or Borrower's business.

                        (g)     Any other provision in this Agreement
notwithstanding, any Lender may at any time create a security interest in, or
pledge, all or any portion of its rights under and interest in this Agreement in
favor of any Federal Reserve Bank in accordance with Regulation A of the Federal
Reserve Bank or U.S. Treasury Regulation 31 CFR Section 203.14, and such Federal
Reserve Bank may enforce such pledge or security interest in any manner
permitted under applicable law.

                14.2    Successors. This Agreement shall bind and inure to the
benefit of the respective successors and assigns of each of the parties;
provided, however, that the Loan Parties may not assign this Agreement or any
rights or duties hereunder without the Lenders' prior written consent and any
prohibited assignment shall be absolutely void ab initio. No consent to



                                      -77-
<PAGE>   84


assignment by the Lenders shall release any Loan Party from its Obligations. A
Lender may assign this Agreement and the other Loan Documents and its rights and
duties hereunder and thereunder pursuant to Section 14.1 hereof and, except as
expressly required pursuant to Section 14.1 hereof, no consent or approval by
Borrower is required in connection with any such assignment.

                15.     AMENDMENTS; WAIVERS.

                15.1    Amendments and Waivers. (i) No amendment or waiver of
any provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by any Loan Party therefrom, shall be effective unless
the same shall be in writing and signed by the Required Lenders (or by Agent at
the written request of the Required Lenders) and Borrower and then any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no such waiver,
amendment, or consent shall, unless in writing and signed by all of the Lenders
affected thereby and Borrower, do any of the following:

                        (a)     increase or extend any Commitment of any Lender,

                        (b)     postpone or delay any date fixed by this
Agreement or any other Loan Document for any payment of principal, interest,
fees, or other amounts due hereunder or under any other Loan Document,

                        (c)     reduce the principal of, or the rate of interest
on, any loan or other extension of credit hereunder, or reduce any fees or other
amounts payable hereunder or under any other Loan Document,

                        (d)     change the percentage of the Commitments that is
required to take any action hereunder,

                        (e)     amend, modify or waive this Section or any
provision of the Agreement providing for consent or other action by all Lenders,

                        (f)     release Collateral other than as permitted by
Section 16.12,

                        (g)     change the definition of "Required Lenders" or
"Pro Rata Share",

                        (h)     contractually subordinate any of Agent's Liens,

                        (i)     release any Loan Party from any obligation for
the payment of money,

                        (j)     change the definitions, or any definitions used
therein, of Borrowing Base, Eligible Fiber Optic Inventory, Maximum Revolver
Amount, or Term Loan Amount,

                        (k)     modify, waive, release or subordinate the
superpriority claim status of the Obligations (except as permitted in this
Agreement and the Loan Documents),

                        (l)     amend any of the provisions of Section 2.1(a),
Section 2.2, Section 2.3(e), Section 2.3(i), Section 2.4(b), Section 3.2(c),
Section 3.3 or Section 16, or

                        (m)     change the definition of Eligible Transferee or
amend, modify or waive any of the provisions of Section 14.

and, provided further, however, that no amendment, waiver or consent shall,
unless in writing and signed by Agent, Issuing Lender, or Swing Lender, as
applicable, affect the rights or duties of Agent, Swing Lender or Issuing
Lenders, as applicable, under this Agreement or any other Loan Document. The
foregoing notwithstanding, any amendment, modification, waiver, consent,
termination, or release of, or with respect to, any provision of this Agreement
or any other Loan Document that relates only to the relationship of the Lender
Group among themselves, and that does not affect the rights or obligations of
Borrower, shall not require consent by or the agreement of Borrower.

                                (ii)    The Agent and the Lenders, have executed
an agreement on the Closing Date pursuant to which the Agent and the Lenders
have agreed to certain intercreditor arrangements, including but not limited to,
certain arrangements regarding voting, allocation of payments, participations in
and buyouts of the Obligations and repayment priorities. The rights and duties
of the Agent and the Lenders with respect to such matters, are subject to such
agreement.

                15.2    Replacement of Holdout Lender.

                        (a)     If any action to be taken by the Lender Group or
Agent hereunder requires the unanimous consent, authorization, or agreement of
all Lenders, and a Lender ("Holdout Lender") fails to give its consent,
authorization, or agreement, then Agent, upon at least 5 Business Days prior
irrevocable notice to the Holdout Lender, may permanently replace the Holdout
Lender with one or more substitute Lenders (each, a "Replacement Lender"), and
the Holdout Lender shall have no right to refuse to be replaced hereunder. Such
notice to replace the Holdout Lender shall specify an effective date for such
replacement, which date shall not be later than 15 Business Days after the date
such notice is given.

                        (b)     Prior to the effective date of such replacement,
the Holdout Lender and each Replacement Lender shall execute and deliver an
Assignment and Acceptance, subject only to the Holdout Lender being repaid its
share of the outstanding Obligations (including an assumption of its Pro Rata
Share of the Risk Participation Liability) without any premium or penalty of any
kind whatsoever. If the Holdout Lender shall refuse or fail to execute and
deliver any such Assignment and Acceptance prior to the effective date of such
replacement, the Holdout Lender shall be deemed to have executed and delivered
such Assignment and Acceptance. The replacement of any Holdout Lender shall be
made in accordance with the terms of Section 14.1. Until such time as the
Replacement Lenders shall have acquired all of the Obligations, the Commitments,
and the other rights and obligations of the Holdout Lender hereunder and under
the other Loan Documents, the Holdout Lender shall remain obligated to make the
Holdout Lender's Pro Rata Share of Advances and to purchased a participation in
each Letter of Credit, in an amount equal to its Pro Rata Share of the Risk
Participation Liability of such Letter of Credit.

                15.3    No Waivers; Cumulative Remedies. No failure by Agent or
any Lender to exercise any right, remedy, or option under this Agreement or any
other Loan Document, or delay by Agent or any Lender in exercising the same,
will operate as a waiver thereof. No waiver by Agent or any Lender will be
effective unless it is in writing, and then only to the extent specifically
stated. No waiver by Agent or any Lender on any occasion shall affect or
diminish Agent's and each Lender's rights thereafter to require strict
performance by Borrower of any provision of this Agreement. Agent's and each
Lender's rights under this Agreement and the other Loan Documents will be
cumulative and not exclusive of any other right or remedy Agent or any Lender
may have.

                16.     AGENT; THE LENDER GROUP.

                16.1    Appointment and Authorization of Agent. Each Lender
hereby designates and appoints Foothill as its representative under this
Agreement and the other Loan Documents and each Lender hereby irrevocably
authorizes Agent to take such action on its behalf under the provisions of this
Agreement and each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to Agent by the terms of this Agreement
or any other Loan Document, together with such powers as are reasonably
incidental thereto. Agent agrees to act as such on the express conditions
contained in this Section 16. The provisions of this Section 16 are solely for
the benefit of Agent, and the Lenders, and Borrower shall have no rights as a
third party beneficiary of any of the provisions contained herein. Any provision
to the contrary contained elsewhere in this Agreement or in any other Loan
Document notwithstanding, Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall Agent have or be deemed to
have any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against Agent;
it being expressly understood and agreed that the use of the word "Agent" is for
convenience only, that Foothill is merely the representative of the Lenders, and
only has the contractual duties set forth herein. Except as expressly otherwise
provided in this Agreement, Agent shall have and may use its sole discretion
with respect to exercising or refraining from exercising any discretionary
rights or taking or refraining from taking any actions that Agent expressly is
entitled to take or assert under or pursuant to this Agreement and the other
Loan Documents. Without limiting the generality of the foregoing, or of any
other provision of the Loan Documents that provides rights or powers to Agent,
Lenders agree that Agent shall have the right to exercise the following powers
as long as this Agreement remains in effect: (a) maintain, in accordance with
its customary business practices, ledgers and records reflecting the status of
the Obligations, the Collateral, the Collections, and related matters, (b)
execute or file any and all financing or similar statements or notices,
amendments, renewals, supplements, documents, instruments, proofs of claim,
notices and other written agreements with respect to the Loan Documents, (c)
make Advances, for itself or on behalf of Lenders as provided in the Loan
Documents, (d) exclusively receive, apply, and distribute the Collections as
provided in the Loan Documents, (e) open and maintain such bank accounts and
cash management arrangements as Agent deems necessary and appropriate in
accordance with the Loan Documents for the foregoing purposes with respect to
the Collateral and the Collections, (f) perform, exercise, and enforce any and
all other rights and remedies of the Lender Group with respect to Borrower, the
Obligations, the Collateral, the Collections, or otherwise related to any of
same as provided in the Loan Documents, and (g)



                                      -80-
<PAGE>   87


incur and pay such Lender Group Expenses as Agent may deem necessary or
appropriate for the performance and fulfillment of its functions and powers
pursuant to the Loan Documents.

                16.2    Delegation of Duties. Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. Agent shall not be responsible
for the negligence or misconduct of any agent or attorney-in-fact that it
selects as long as such selection was made without gross negligence or willful
misconduct.

                16.3    Liability of Agent. None of the Agent-Related Persons
shall (i) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by Borrower or any
Subsidiary or Affiliate of Borrower, or any officer or director thereof,
contained in this Agreement or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
Borrower or any other party to any Loan Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation
to any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the Books or properties of Borrower or the
books or records or properties of any of Borrower's Subsidiaries or Affiliates.

                16.4    Reliance by Agent. Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent, or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to Borrower or counsel to any Lender), independent accountants and other experts
selected by Agent. Agent shall be fully justified in failing or refusing to take
any action under this Agreement or any other Loan Document unless Agent shall
first receive such advice or concurrence of the Lenders as it deems appropriate
and until such instructions are received, Agent shall act, or refrain from
acting, as it deems advisable. If Agent so requests, it shall first be
indemnified to its reasonable satisfaction by Lenders against any and all
liability and expense that may be incurred by it by reason of taking or
continuing to take any such action. Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement or any other Loan
Document in accordance with a request or consent of Lenders and such request and
any action taken or failure to act pursuant thereto shall be binding upon all of
Lenders.

                16.5    Notice of Default or Event of Default. Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default, except with respect to defaults in the payment of principal,
interest, fees, and expenses required to be paid to Agent for the account of the
Lenders, except with respect to Events of Default of which Agent has actual
knowledge, unless Agent shall have received written notice from Lenders or
Borrower referring to this Agreement, describing such Default or Event of
Default, and stating that such notice is a



                                      -81-
<PAGE>   88


"notice of default." Agent promptly will notify the Lenders of its receipt of
any such notice or of any Event of Default of which Agent has actual knowledge.
If any Lender obtains actual knowledge of any Event of Default, such Lender
promptly shall notify the other Lenders and Agent of such Event of Default. Each
Lender shall be solely responsible for giving any notices to its Participants,
if any. Subject to Section 16.4, Agent shall take such action with respect to
such Default or Event of Default as may be requested by the Required Lenders in
accordance with Section 9; provided, however, that unless and until Agent has
received any such request, Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable.

                16.6    Credit Decision. Each Lender acknowledges that none of
the Agent-Related Persons has made any representation or warranty to it, and
that no act by Agent hereinafter taken, including any review of the affairs of
Borrower and its Subsidiaries or Affiliates, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Lender. Each
Lender represents to Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of Borrower and any other Person (other than the Lender Group)
party to a Loan Document, and all applicable bank regulatory laws relating to
the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to Borrower. Each Lender also represents
that it will, independently and without reliance upon any Agent-Related Person
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of Borrower and any other Person (other than the Lender Group)
party to a Loan Document. Except for notices, reports, and other documents
expressly herein required to be furnished to the Lenders by Agent, Agent shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of Borrower and any other
Person party to a Loan Document that may come into the possession of any of the
Agent-Related Persons.

                16.7    Costs and Expenses; Indemnification. Agent may incur and
pay Lender Group Expenses to the extent Agent reasonably deems necessary or
appropriate for the performance and fulfillment of its functions, powers, and
obligations pursuant to the Loan Documents, including court costs, reasonable
attorneys fees and expenses, costs of collection by outside collection agencies
and auctioneer fees and costs of security guards or insurance premiums paid to
maintain the Collateral, whether or not Borrower is obligated to reimburse Agent
or Lenders for such expenses pursuant to the Loan Agreement or otherwise. Agent
is authorized and directed to deduct and retain sufficient amounts from
Collections received by Agent to reimburse Agent for such out-of-pocket costs
and expenses prior to the distribution of any amounts to Lenders. In the event
Agent is not reimbursed for such costs and expenses from Collections received by
Agent, each Lender hereby agrees that it is and shall be obligated to pay to or
reimburse Agent for the amount of such Lender's Pro Rata Share thereof. Whether
or not the transactions contemplated hereby are consummated, the Lenders shall
indemnify upon



                                      -82-
<PAGE>   89


demand the Agent-Related Persons (to the extent not reimbursed by or on behalf
of Borrower and without limiting the obligation of Borrower to do so), according
to their Pro Rata Shares, from and against any and all Indemnified Liabilities;
provided, however, that no Lender shall be liable for the payment to any
Agent-Related Person of any portion of such Indemnified Liabilities resulting
solely from such Person's gross negligence or willful misconduct nor shall any
Lender be liable for the obligations of any Defaulting Lender in failing to make
an Advance or other extension of credit hereunder. Without limitation of the
foregoing, each Lender shall reimburse Agent upon demand for such Lender's
ratable share of any costs or out-of-pocket expenses (including attorneys fees
and expenses) incurred by Agent in connection with the preparation, execution,
delivery, administration, modification, amendment, or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement, any other Loan
Document, or any document contemplated by or referred to herein, to the extent
that Agent is not reimbursed for such expenses by or on behalf of Borrower. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of Agent.

                16.8    Agent in Individual Capacity. Foothill and its
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in, and generally engage in any kind of
banking, lending, trust, financial advisory, underwriting, or other business
with Borrower and its Subsidiaries and Affiliates and any other Person (other
than the Lender Group) party to any Loan Documents as though Foothill were not
Agent hereunder, and, in each case, without notice to or consent of the other
members of the Lender Group. The other members of the Lender Group acknowledge
that, pursuant to such activities, Foothill or its Affiliates may receive
information regarding Borrower or its Affiliates and any other Person (other
than the Lender Group) party to any Loan Documents that is subject to
confidentiality obligations in favor of Borrower or such other Person and that
prohibit the disclosure of such information to the Lenders, and the Lenders
acknowledge that, in such circumstances (and in the absence of a waiver of such
confidentiality obligations, which waiver Agent will use its reasonable best
efforts to obtain), Agent shall not be under any obligation to provide such
information to them. The terms "Lender" and "Lenders" include Foothill in its
individual capacity.

                16.9    Successor Agent. Agent may resign as Agent upon 45 days
notice to the Lenders and the Borrower. If Agent resigns under this Agreement,
the Required Lenders shall appoint a successor Agent for the Lenders. If no
successor Agent is appointed prior to the effective date of the resignation of
Agent, Agent may appoint, after consulting with the Lenders, a successor Agent.
If Agent has materially breached or failed to perform any material provision of
this Agreement or of applicable law, the Required Lenders may agree in writing
to remove and replace Agent with a successor Agent from among the Lenders. In
any such event, upon the acceptance of its appointment as successor Agent
hereunder, such successor Agent shall succeed to all the rights, powers, and
duties of the retiring Agent and the term "Agent" shall mean such successor
Agent and the retiring Agent's appointment, powers, and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 16 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement. If no
successor Agent has accepted appointment as Agent by the date which is 45 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Lenders shall
perform all of



                                      -83-
<PAGE>   90


the duties of Agent hereunder until such time, if any, as the Lenders appoint a
successor Agent as provided for above.

                16.10   Lender in Individual Capacity. Any Lender and its
respective Affiliates may make loans to, issue letters of credit for the account
of, accept deposits from, acquire equity interests in and generally engage in
any kind of banking, trust, financial advisory, underwriting or other business
with Borrower and its Subsidiaries and Affiliates and any other Person (other
than the Lender Group) party to any Loan Documents as though such Lender were
not a Lender hereunder without notice to or consent of the other members of the
Lender Group. The other members of the Lender Group acknowledge that, pursuant
to such activities, such Lender and its respective Affiliates may receive
information regarding Borrower or its Affiliates and any other Person (other
than the Lender Group) party to any Loan Documents that is subject to
confidentiality obligations in favor of Borrower or such other Person and that
prohibit the disclosure of such information to the Lenders, and the Lenders
acknowledge that, in such circumstances (and in the absence of a waiver of such
confidentiality obligations, which waiver such Lender will use its reasonable
best efforts to obtain), such Lender not shall be under any obligation to
provide such information to them. Notwithstanding anything to the contrary, the
Lenders and the Agent acknowledge that any Lender which is an Affiliate of the
Borrower may be prohibited by fiduciary duties or other laws from disclosing
certain information to the Agent and the Lenders, and in any such case said
Lender shall not have any obligation to obtain such waivers or to make such
disclosure.

                16.11   Swing Lender in Individual Capacity. With respect to the
Swing Loans and Agent Advances, Swing Lender shall have the same rights and
powers under this Agreement as any other Lender and may exercise the same as
though it were not the sub-agent of Agent.

                16.12   Withholding Taxes.

                        (a)     If any Lender is a "foreign corporation,
partnership or trust" within the meaning of the IRC and such Lender claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the IRC, such Lender agrees with and in favor of Agent and Borrower, to
deliver to Agent and Borrower:

                                (i)     if such Lender claims an exemption from
        withholding tax pursuant to its portfolio interest exception, (a) a
        statement of the Lender, signed under penalty of perjury, that it is not
        a (I) a "bank" as described in Section 881(c)(3)(A) of the IRC, (II) a
        10% shareholder (within the meaning of Section 881(c)(3)(B) of the IRC),
        or (III) a controlled foreign corporation described in Section
        881(c)(3)(C) of the IRC, and (B) a properly completed IRS Form W-8BEN,
        before the first payment of any interest under this Agreement and at any
        other time reasonably requested by Agent or Borrower;

                                (ii)    if such Lender claims an exemption from,
        or a reduction of, withholding tax under a United States tax treaty,
        properly completed IRS Form W-8BEN before the first payment of any
        interest under this Agreement and at any other time reasonably requested
        by Agent or Borrower;



                                      -84-
<PAGE>   91


                                (iii)   if such Lender claims that interest paid
        under this Agreement is exempt from United States withholding tax
        because it is effectively connected with a United States trade or
        business of such Lender, two properly completed and executed copies of
        IRS Form W-8ECI before the first payment of any interest is due under
        this Agreement and at any other time reasonably requested by Agent or
        Borrower;

                                (iv)    such other form or forms as may be
        required under the IRC or other laws of the United States as a condition
        to exemption from, or reduction of, United States withholding tax.

                Such Lender agrees promptly to notify Agent and Borrower of any
change in circumstances which would modify or render invalid any claimed
exemption or reduction.

                        (b)     If any Lender claims exemption from, or
reduction of, withholding tax under a United States tax treaty by providing IRS
Form W-8BEN and such Lender sells, assigns, grants a participation in, or
otherwise transfers all or part of the Obligations of Borrower to such Lender,
such Lender agrees to notify Agent of the percentage amount in which it is no
longer the beneficial owner of Obligations of Borrower to such Lender. To the
extent of such percentage amount, Agent will treat such Lender's IRS Form W-8BEN
as no longer valid.

                        (c)     If any Lender is entitled to a reduction in the
applicable withholding tax, Agent may withhold from any interest payment to such
Lender an amount equivalent to the applicable withholding tax after taking into
account such reduction. If the forms or other documentation required by
subsection (a) of this Section are not delivered to Agent, then Agent may
withhold from any interest payment to such Lender not providing such forms or
other documentation an amount equivalent to the applicable withholding tax.

                        (d)     If the Internal Revenue Service or any other
Governmental Authority of the United States or other jurisdiction asserts a
claim that Agent did not properly withhold tax from amounts paid to or for the
account of any Lender (because the appropriate form was not delivered, was not
properly executed, or because such Lender failed to notify Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Lender shall indemnify and hold
Agent harmless for all amounts paid, directly or indirectly, by Agent as tax or
otherwise, including penalties and interest, and including any taxes imposed by
any jurisdiction on the amounts payable to Agent under this Section, together
with all costs and expenses (including attorneys fees and expenses). The
obligation of Lenders under this subsection shall survive the payment of all
Obligations and the resignation or replacement of Agent.

                        (e)     All payments made by Borrower hereunder or under
any note will be made without setoff, counterclaim, or other defense, except as
required by applicable law other than for Taxes (as defined below). All such
payments will be made free and clear of, and without deduction or withholding
for, any present or future taxes, levies, imposts, duties, fees, assessments or
other charges of whatever nature now or hereafter imposed by any jurisdiction
(other than the United States) or by any political subdivision or taxing
authority thereof or therein (other than of the United States) with respect to
such payments (but excluding, any tax imposed by any jurisdiction or by any
political subdivision or taxing authority thereof or therein



                                      -85-
<PAGE>   92


(i) measured by or based on the net income or net profits of a Lender, or (ii)
to the extent that such tax results from a change in the circumstances of the
Lender, including a change in the residence, place of organization, or principal
place of business of the Lender, or a change in the branch or lending office of
the Lender participating in the transactions set forth herein) and all interest,
penalties or similar liabilities with respect thereto (all such non-excluded
taxes, levies, imposts, duties, fees, assessments or other charges being
referred to collectively as "Taxes"). If any Taxes are so levied or imposed,
Borrower agrees to pay the full amount of such Taxes, and such additional
amounts as may be necessary so that every payment of all amounts due under this
Agreement or under any note, including any amount paid pursuant to this Section
16.11(e) after withholding or deduction for or on account of any Taxes, will not
be less than the amount provided for herein; provided, however, that Borrower
shall not be required to increase any such amounts payable to Agent or any
Lender (i) that is not organized under the laws of the United States, if such
Person fails to comply with the other requirements of this Section 16.11, or
(ii) if the increase in such amount payable results from Agent's or such
Lender's own willful misconduct or gross negligence. Borrower will furnish to
Agent as promptly as possible after the date the payment of any Taxes is due
pursuant to applicable law certified copies of tax receipts evidencing such
payment by Borrower.

                16.13   Collateral Matters.

                        (a)     Lenders hereby irrevocably authorize Agent, at
its option and in its sole discretion, to release or subordinate any Lien on any
Collateral (i) upon the termination of the Commitments and payment and
satisfaction in full by Borrower of all Obligations, (ii) constituting property
being sold or disposed of if a release is required or desirable in connection
therewith and, in the case of material property or assets of a Loan Party, if
Borrower certifies to Agent that the sale or disposition is permitted under
Section 7.4 of this Agreement or the other Loan Documents (and Agent may rely
conclusively on any such certificate, without further inquiry), (iii)
constituting property in which Borrower owned no interest at the time the
security interest was granted or at any time thereafter, or (iv) constituting
property leased to Borrower under a lease that has expired or is terminated in a
transaction permitted under this Agreement. Except as provided above, Agent will
not execute and deliver a release of any Lien on any Collateral without the
prior written authorization of (y) if the release is of all or any substantial
portion of the Collateral, all of the Lenders, or (z) otherwise, the Required
Lenders. Upon request by Agent or Borrower at any time, the Lenders will confirm
in writing Agent's authority to release any such Liens on particular types or
items of Collateral pursuant to this Section 16.12; provided, however, that (1)
Agent shall not be required to execute any document necessary to evidence such
release on terms that, in Agent's opinion, would expose Agent to liability or
create any obligation or entail any consequence other than the release of such
Lien without recourse, representation, or warranty, and (2) such release shall
not in any manner discharge, affect, or impair the Obligations or any Liens
(other than those expressly being released) upon (or obligations of Borrower in
respect of) all interests retained by Borrower, including, the proceeds of any
sale, all of which shall continue to constitute part of the Collateral.

                        (b)     Agent shall have no obligation whatsoever to any
of the Lenders to assure that the Collateral exists or is owned by Borrower or
is cared for, protected, or insured or has been encumbered, or that the Agent's
Liens have been properly or sufficiently or lawfully created, perfected,
protected, or enforced or are entitled to any particular priority, or to
exercise



                                      -86-
<PAGE>   93


at all or in any particular manner or under any duty of care, disclosure or
fidelity, or to continue exercising, any of the rights, authorities and powers
granted or available to Agent pursuant to any of the Loan Documents, it being
understood and agreed that in respect of the Collateral, or any act, omission,
or event related thereto, subject to the terms and conditions contained herein,
Agent may act in any manner it may deem appropriate, in its sole discretion
given Agent's own interest in the Collateral in its capacity as one of the
Lenders and that Agent shall have no other duty or liability whatsoever to any
Lender as to any of the foregoing, except as otherwise provided herein.

                16.14   Restrictions on Actions by Lenders; Sharing of Payments.

                        (a)     Each of Lenders agrees that it shall not,
without the express consent of Agent, and that it shall, to the extent it is
lawfully entitled to do so, upon the request of Agent, set off against the
Obligations, any amounts owing by such Lender to Borrower or any deposit
accounts of Borrower now or hereafter maintained with such Lender. Each of the
Lenders further agrees that it shall not, unless specifically requested to do so
by Agent, take or cause to be taken any action, including, the commencement of
any legal or equitable proceedings, to foreclose any Lien on, or otherwise
enforce any security interest in, any of the Collateral the purpose of which is,
or could be, to give such Lender any preference or priority against the other
Lenders with respect to the Collateral.

                        (b)     If, at any time or times any Lender shall
receive (i) by payment, foreclosure, setoff, or otherwise, any proceeds of
Collateral or any payments with respect to the Obligations arising under, or
relating to, this Agreement or the other Loan Documents, except for any such
proceeds or payments received by such Lender from Agent pursuant to the terms of
this Agreement, or (ii) payments from Agent in excess of such Lender's Pro Rata
Share of all such distributions by Agent, such Lender promptly shall (1) turn
the same over to Agent, in kind, and with such endorsements as may be required
to negotiate the same to Agent, or in immediately available funds, as
applicable, for the account of all of the Lenders and for application to the
Obligations in accordance with the applicable provisions of this Agreement, or
(2) purchase, without recourse or warranty, an undivided interest and
participation in the Obligations owed to the other Lenders so that such excess
payment received shall be applied ratably as among Lenders in accordance with
their Pro Rata Shares; provided, however, that if all or part of such excess
payment received by the purchasing party is thereafter recovered from it, those
purchases of participations shall be rescinded in whole or in part, as
applicable, and the applicable portion of the purchase price paid therefor shall
be returned to such purchasing party, but without interest except to the extent
that such purchasing party is required to pay interest in connection with the
recovery of the excess payment.

                16.15   Agency for Perfection. Agent hereby appoints each other
Lender as its agent (and each Lender hereby accepts such appointment) for the
purpose of perfecting the Agent's Liens in assets which, in accordance with
Article 9 of the UCC can be perfected only by possession. Should any Lender
obtain possession of any such Collateral, such Lender shall notify Agent
thereof, and, promptly upon Agent's request therefor shall deliver such
Collateral to Agent or in accordance with Agent's instructions.



                                      -87-
<PAGE>   94


                16.16   Payments by Agent to the Lenders. All payments to be
made by Agent to Lenders shall be made by bank wire transfer or internal
transfer of immediately available funds pursuant to such wire transfer
instructions as each party may designate for itself by written notice to Agent.
Concurrently with each such payment, Agent shall identify whether such payment
(or any portion thereof) represents principal, premium, or interest of the
Obligations.

                16.17   Concerning the Collateral and Related Loan Documents.
Each member of Lender Group authorizes and directs Agent to enter into this
Agreement and the other Loan Documents relating to the Collateral, for the
benefit of the Lender Group. Each member of the Lender Group agrees that any
action taken by Agent in accordance with the terms of this Agreement or the
other Loan Documents relating to the Collateral and the exercise by Agent of its
powers set forth therein or herein, together with such other powers that are
reasonably incidental thereto, shall be binding upon all of the Lenders.

                16.18   Field Audits and Examination Reports; Confidentiality;
Disclaimers by Lenders; Other Reports and Information. By becoming a party to
this Agreement, each Lender:

                        (a)     is deemed to have requested that Agent furnish
such Lender, promptly after it becomes available, a copy of each field audit or
examination report (each a "Report" and collectively, "Reports") prepared by or
at the request of Agent, and Agent shall so furnish each Lender with such
Reports,

                        (b)     expressly agrees and acknowledges that Agent
does not (i) make any representation or warranty as to the accuracy of any
Report, and (ii) shall not be liable for any information contained in any
Report,

                        (c)     expressly agrees and acknowledges that the
Reports are not comprehensive audits or examinations, that Agent or other party
performing any audit or examination will inspect only specific information
regarding Borrower and will rely significantly upon the Books, as well as on
representations of Borrower's personnel,

                        (d)     agrees to keep all Reports and other material,
non-public information regarding Borrower and its Subsidiaries and their
operations, assets, and existing and contemplated business plans in a
confidential manner; it being understood and agreed by Borrower that in any
event such Lender may make disclosures (a) to counsel for and other advisors,
accountants, and auditors to such Lender, (b) reasonably required by any bona
fide potential or actual Assignee or Participant in connection with any
contemplated or actual assignment or transfer by such Lender of an interest
herein or any participation interest in such Lender's rights hereunder, (c) of
information that has become public by disclosures made by Persons other than
such Lender, its Affiliates, assignees, transferees, or Participants, or (d) as
required or requested by any court, governmental or administrative agency,
pursuant to any subpoena or other legal process, or by any law, statute,
regulation, or court order; provided, however, that, unless prohibited by
applicable law, statute, regulation, or court order, such Lender shall notify
Borrower of any request by any court, governmental or administrative agency, or
pursuant to any subpoena or other legal process for disclosure of any such
non-public material information concurrent with, or where practicable, prior to
the disclosure thereof, and



                                      -88-
<PAGE>   95


                        (e)     without limiting the generality of any other
indemnification provision contained in this Agreement, agrees: (i) to hold Agent
and any other Lender preparing a Report harmless from any action the
indemnifying Lender may take or conclusion the indemnifying Lender may reach or
draw from any Report in connection with any loans or other credit accommodations
that the indemnifying Lender has made or may make to Borrower, or the
indemnifying Lender's participation in, or the indemnifying Lender's purchase
of, a loan or loans of Borrower, and (ii) to pay and protect, and indemnify,
defend and hold Agent, and any such other Lender preparing a Report harmless
from and against, the claims, actions, proceedings, damages, costs, expenses,
and other amounts (including, attorneys fees and costs) incurred by Agent and
any such other Lender preparing a Report as the direct or indirect result of any
third parties who might obtain all or part of any Report through the
indemnifying Lender.

                In addition to the foregoing: (x) any Lender may from time to
time request of Agent in writing that Agent provide to such Lender a copy of any
report or document provided by Borrower to Agent that has not been
contemporaneously provided by Borrower to such Lender, and, upon receipt of such
request, Agent promptly shall provide a copy of same to such Lender, (y) to the
extent that Agent is entitled, under any provision of the Loan Documents, to
request additional reports or information from Borrower, any Lender may, from
time to time, reasonably request Agent to exercise such right as specified in
such Lender's notice to Agent, whereupon Agent promptly shall request of
Borrower the additional reports or information reasonably specified by such
Lender, and, upon receipt thereof from Borrower, Agent promptly shall provide a
copy of same to such Lender, and (z) any time that Agent renders to Borrower a
statement regarding the Loan Account, Agent shall send a copy of such statement
to each Lender.

                16.19   Several Obligations; No Liability. Notwithstanding that
certain of the Loan Documents now or hereafter may have been or will be executed
only by or in favor of Agent in its capacity as such, and not by or in favor of
Lenders, any and all obligations on the part of Lenders (if any) to make any
credit available hereunder shall constitute the several (and not joint)
obligations of the respective Lenders on a ratable basis, according to their
respective Commitments, to make an amount of such credit not to exceed, in
principal amount, at any one time outstanding, the amount of their respective
Commitments. Nothing contained herein shall confer upon any Lender any interest
in, or subject any Lender to any liability for, or in respect of, the business,
assets, profits, losses, or liabilities of any other Lender. Each Lender shall
be solely responsible for notifying its Participants of any matters relating to
the Loan Documents to the extent any such notice may be required, and no Lender
shall have any obligation, duty, or liability to any Participant of any other
Lender. Except as provided in Section 16.7, no member of Lender Group shall have
any liability for the acts or any other member of the Lender Group. No Lender
shall be responsible to Borrower or any other Person for any failure by any
other Lender to fulfill its obligations to make credit available hereunder, nor
to advance for it or on its behalf in connection with its Commitment, nor to
take any other action on its behalf hereunder or in connection with the
financing contemplated herein.

                16.20   Co-Agent. Notwithstanding the provisions of this
Agreement or any of the other Loan Documents, Ableco Finance LLC (in its
capacity as Co-Agent as opposed to its capacity as a Lender) shall have no
powers, rights, duties, responsibilities, or liabilities with respect to this
Agreement and the other Loan Documents (except as expressly provided in this



                                      -89-
<PAGE>   96


Agreement) nor shall Ableco Finance LLC (in such capacity as Co-Agent) have or
be deemed to have any fiduciary relationship with any Lender.

                17.     GUARANTY.

                17.1    Guaranty. Each Guarantor hereby unconditionally and
irrevocably jointly and severally guarantees the punctual payment when due,
whether at stated maturity, by acceleration or otherwise, of all Obligations of
the Borrower now or hereafter existing under any Loan Document, whether for
principal, interest fees, expenses or otherwise (such obligations, to the extent
not paid by the Borrower, being the "Guaranteed Obligations"), and agrees to pay
any and all expenses (including reasonable counsel fees and expenses) incurred
by the Lender Group in enforcing any rights under the guaranty set forth in this
Article.

                17.2    Guaranty Absolute. Each Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of the
Loan Documents, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Agent, or the Lenders with respect thereto. The obligations of each Guarantor
under this Article are independent of the Guaranteed Obligations, and a separate
action or actions may be brought and prosecuted against each Guarantor to
enforce such obligations, irrespective of whether any action is brought against
Borrower or whether Borrower is joined in any such action or actions. The
liability of each Guarantor under this Article shall be irrevocable, absolute
and unconditional irrespective of, and each Guarantor hereby irrevocably waives
any defenses it may now or hereafter have in any way relating to, any or all of
the following:

                        (a)     any lack of validity or enforceability of any
Loan Document or any agreement or instrument relating thereto;

                        (b)     any change in the time, manner or place of
payment of, or in any other term of, all or any of the Guaranteed Obligations,
or any other amendment or waiver of or any consent to departure from any Loan
Document, including, without limitation, any increase in the Guaranteed
Obligations resulting from the extension of additional credit to Borrower or
otherwise;

                        (c)     any taking, exchange, release or non-perfection
of any Collateral, or any taking, release or amendment or waiver of or consent
to departure from any other guaranty, for all or any of the Guaranteed
Obligations;

                        (d)     any change, restructuring or termination of the
corporate, limited liability company or partnership structure or existence of
any Borrower; or

                        (e)     any other circumstance (including, without
limitation, any statute of limitations) or any existence of or reliance on any
representation by the Agent, or the Lenders that might otherwise constitute a
defense available to, or a discharge of, any Guarantor, any Borrower or any
other guarantor or surety.



                                      -90-
<PAGE>   97


This Article shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by the Agent or the Lenders or any other Person,
all as though such payment had not been made.

                17.3    Waiver. Each Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Article and any requirement that the Agent, or
the Lenders exhaust any right or take any action against any Borrower or any
other Person or any Collateral. Each Guarantor acknowledges that it will receive
direct and indirect benefits from the financing arrangements contemplated herein
and that the waiver set forth in this Section 17.3 is knowingly made in
contemplation of such benefits. Each Guarantor hereby waives any right to revoke
this Article, and acknowledges that this Article is continuing in nature and
applies to all Guaranteed Obligations, whether existing now or in the future.

                17.4    Continuing Guaranty; Assignments. This Article is a
continuing guaranty and shall (a) remain in full force and effect until the
later of the cash payment in full of the Guaranteed Obligations (other than
indemnification obligations as to which no claim has been made) and all other
amounts payable under this Article and the Maturity Date, (b) be binding upon
each Guarantor, its successors and assigns and (c) inure to the benefit of and
be enforceable by the Agent, and the Lenders and their successors, pledgees,
transferees and assigns. Without limiting the generality of the foregoing clause
(c), any Lender may pledge, assign or otherwise transfer all or any portion of
its rights and obligations under this Agreement (including, without limitation,
all or any portion of its Commitments, its loans, owing to it and any note held
by it) to any other Person, and such other Person shall thereupon become vested
with all the benefits in respect thereof granted such Lender herein or
otherwise, in each case as provided in Article 14.

                17.5    Subrogation. No Guarantor will exercise any rights that
it may now or hereafter acquire against any Borrower or any other insider
guarantor that arise from the existence, payment, performance or enforcement of
such Guarantor's obligations under this Article, including, without limitation,
any right of subrogation, reimbursement, exoneration, contribution or
indemnification and any right to participate in any claim or remedy of the Agent
and the Lenders against any Borrower or any other insider guarantor or any
Collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from any Borrower or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security solely on account of such claim, remedy or right, unless and
until all of the Guaranteed Obligations and all other amounts payable under this
Article shall have been paid in full in cash and the Maturity Date shall have
occurred. If any amount shall be paid to any Guarantor in violation of the
immediately preceding sentence at any time prior to the later of the payment in
full in cash of the Guaranteed Obligations and all other amounts payable under
this Article and the Maturity Date, such amount shall be held in trust for the
benefit of the Agent and the Lenders and shall forthwith be paid to the Agent
and the Lenders to be credited and applied to the Guaranteed Obligations and all
other amounts payable under this Article, whether matured or unmatured, in
accordance with the terms of this Agreement, or to be held as collateral for any
Guaranteed Obligations or other amounts payable under this Article thereafter
arising. If (i) any Guarantor shall make payment to the Agent and the Lenders of
all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed
Obligations and all other amounts payable under this



                                      -91-
<PAGE>   98


Article shall be paid in full in cash and (iii) the Maturity Date shall have
occurred, the Agent and the Lenders will, at such Guarantor's request and
expense, execute and deliver to such Guarantor appropriate documents, without
recourse and without representation or warranty, necessary to evidence the
transfer by subrogation to such Guarantor of an interest in the Guaranteed
Obligations resulting from such payment by such Guarantor.

                17.6    The guarantee by each Guarantor of the Guaranteed
Obligations is a joint and several obligation of each Guarantor.

                18.     GENERAL PROVISIONS.

                18.1    Effectiveness. This Agreement shall be binding and
deemed effective when executed by each Loan Party, Agent, and each Lender whose
signature is provided for on the signature pages hereof.

                18.2    Section Headings. Headings and numbers have been set
forth herein for convenience only. Unless the contrary is compelled by the
context, everything contained in each Section applies equally to this entire
Agreement.

                18.3    Interpretation. Neither this Agreement nor any
uncertainty or ambiguity herein shall be construed against Lender Group or
Borrower, whether under any rule of construction or otherwise. On the contrary,
this Agreement has been reviewed by all parties and shall be construed and
interpreted according to the ordinary meaning of the words used so as to
accomplish fairly the purposes and intentions of all parties hereto.

                18.4    Severability of Provisions. Each provision of this
Agreement shall be severable from every other provision of this Agreement for
the purpose of determining the legal enforceability of any specific provision.

                18.5    Amendments in Writing. This Agreement only can be
amended by a writing signed by Agent (on behalf of the requisite number of
Lenders required by this Agreement) and Borrower (on behalf of the Loan
Parties).

                18.6    Counterparts; Telefacsimile Execution. This Agreement
may be executed in any number of counterparts and by different parties on
separate counterparts, each of which, when executed and delivered, shall be
deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement. Delivery of an executed counterpart
of this Agreement by telefacsimile shall be equally as effective as delivery of
an original executed counterpart of this Agreement. Any party delivering an
executed counterpart of this Agreement by telefacsimile also shall deliver an
original executed counterpart of this Agreement but the failure to deliver an
original executed counterpart shall not affect the validity, enforceability, and
binding effect of this Agreement. The foregoing shall apply to each other Loan
Document mutatis mutandis.

                18.7    Revival and Reinstatement of Obligations. If the
incurrence or payment of the Obligations by Borrower or Guarantor or the
transfer to the Lender Group of any property should for any reason subsequently
be declared to be void or voidable under any state or federal law relating to
creditors' rights, including provisions of the Bankruptcy Code relating to



                                      -92-
<PAGE>   99


fraudulent conveyances, preferences, or other voidable or recoverable payments
of money or transfers of property (collectively, a "Voidable Transfer"), and if
Lender Group is required to repay or restore, in whole or in part, any such
Voidable Transfer, or elects to do so upon the reasonable advice of its counsel,
then, as to any such Voidable Transfer, or the amount thereof that the Lender
Group is required or elects to repay or restore, and as to all reasonable costs,
expenses, and attorneys fees of the Lender Group related thereto, the liability
of Borrower or Guarantor automatically shall be revived, reinstated, and
restored and shall exist as though such Voidable Transfer had never been made.

                18.8    Integration. This Agreement, together with the other
Loan Documents, reflects the entire understanding of the parties with respect to
the transactions contemplated hereby and shall not be contradicted or qualified
by any other agreement, oral or written, before the date hereof.

                18.9    Agent as Party in Interest. Each Loan Party hereby
stipulates and agrees that Agent is and shall remain a party in interest in the
Chapter 11 Cases and shall have the right to participate, object and be heard in
any motion or proceeding in connection therewith. Without limitation of the
foregoing, Agent shall have the right to make any motion or raise any objection
it deems to be in its interest (specifically including but not limited to
objections to use of proceeds of the Advances and the Term Loan, to payment of
professional fees and expenses or the amount thereof, to sales or other
transactions outside the ordinary course of business or to assumption or
rejection of any executory contract or lease).

                18.10   Confidentiality. Except as otherwise provided in this
Agreement, Agent and each of the Lenders shall not disclose any Confidential
Information to any Person without the consent of Borrower, other than (a) to
Agent's or a Lender's Affiliates and its officers, directors, employees, agents
and advisors and to actual or prospective assignees and participants, and then
only on a confidential basis; (b) as required by any law, rule, or regulation or
judicial process; and (c) as requested or required by any state, federal, or
foreign authority or examiner regulating banks or banking. If Agent or a Lender
is required by any law, rule, or regulation or judicial process to disclose any
Confidential Information, to the extent permitted by applicable law, it shall
promptly give notice to Borrower so that Borrower may seek a protective order or
other appropriate remedy. If Borrower does not obtain such a protective order or
other remedy, to the extent permitted by applicable law, Agent or the Lender, as
applicable, will endeavor to furnish only that portion of the Confidential
Information which it reasonably believes to be legally required.
