deposited in an interest-bearing account (the "REINVESTMENT ACCOUNT") which
shall be maintained by the Borrower with the Administrative Agent, and which
shall be under the sole dominion and control of the Administrative Agent. During

day on which such net cash proceeds were received and the amount of such
prepayment shall be the excess, if any, of such Asset Restoration Amount over
the amount thereof used by the Borrower for repairs or replacements prior to
such 90th day. The Asset Restoration Amount shall be deposited in an


                                       16

<PAGE>

interest-bearing account (the "RESERVE ACCOUNT") which shall be maintained by

kind then used or usable in the business of the Borrower, and on the Business

                           (ii) EFFECT OF REDUCTIONS. Simultaneously with each
voluntary permanent reduction, the Borrower shall make a payment of the
outstanding Revolving Credit Loans equal to the excess, if any, of (A) the
aggregate principal amount of the outstanding Revolving Credit Loans and the
Stated Amount of any Letters of Credit over (B) the Revolving Credit Loan
Commitments, as so reduced. Notice of a reduction, once given, shall be

warranties to the Administrative Agent, the Lenders and the Issuing Bank, all of
which shall survive the execution and delivery of this Agreement and the making
of the Loans and other extensions of credit:

         SECTION 5.1 ORGANIZATION, POWER AND AUTHORITY. The Borrower is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware;

                                       22

<PAGE>

each Subsidiary of the Borrower is duly organized, validly existing and in good
standing under the laws of the state of its incorporation or organization; and
the Borrower and each Subsidiary of the Borrower are in good standing as foreign
corporations authorized to do business in each jurisdiction where the nature of
their respective activities or the ownership of their respective properties
makes such qualification or licensing necessary, other than jurisdictions in
which failure to be so qualified would not, individually or in the aggregate,
have a Material Adverse Effect. The Borrower and each of its Subsidiaries has
the corporate power and authority to own or hold under lease the properties it
purports to own or hold under lease, to transact the business it transacts or
proposes to transact, to execute and deliver the Loan Documents to which it is a
party and to perform the provisions thereof.

         SECTION 5.2 AUTHORIZATION; ETC. The Loan Documents to which each Loan
Party is a party have been duly authorized by all necessary corporate action on
the part of such Loan Party, and each of the Loan Documents constitute a legal,
valid and binding obligation of the Loan Party executing the same, enforceable
against such Loan Party in accordance with its terms except as such
enforceability may be limited by (a) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforceability of
creditor's rights generally and (b) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).
The individuals who represent themselves to the Administrative Agent, the
Lenders and the Issuing Bank as holding one or more of the following executive
officer positions with the Borrower at the time of making a certification
hereunder shall be authorized to execute and deliver on behalf of the Borrower
the certifications contemplated under this Agreement to be delivered in the
future (each an "AUTHORIZED OFFICER"): Philip J. Balsamo.

         SECTION 5.3 FINANCIAL STATEMENTS. The Borrower has delivered or caused
to be delivered to the Administrative Agent copies of the Consolidated financial
statements of the Borrower. All of said financial statements (including in each
case the related schedules and notes) fairly present in all material respects
the financial condition of the Borrower and its Subsidiaries, on a consolidated
basis, as of the respective dates specified therein and the results of
operations and cash flows for the respective periods so specified and have been
prepared in accordance with GAAP consistently applied throughout the periods
involved except as set forth in the notes thereto (subject, in the case of any
interim financial statements, to the omission of notes thereto and normal
year-end adjustments).

         SECTION 5.4 NO MATERIAL ADVERSE EFFECT. Since the most recent balance
sheet of the Borrower delivered to the Administrative Agent, neither the
Borrower nor any Subsidiary of the Borrower has suffered any damage, destruction
or loss to any Material part of its assets (tangible or intangible), and no
event or circumstance has occurred or exists, which individually or in the
aggregate has resulted or could reasonably be expected to result in a Material
Adverse Effect.

         SECTION 5.5 NO DEFAULTS, VIOLATIONS OR CONFLICTS; ETC. The execution,
delivery and performance by the Loan Parties of the Loan Documents will not (a)
contravene, result in any breach of, or constitute a default under, or result in
the creation of any Lien in respect of any property of any Loan Party under, the
corporate charter, by-laws, or similar constituent documents, or any Material
indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease,
or any other Material agreement or instrument to which any Loan Party is


                                       23

<PAGE>

bound or by which any Loan Party or any of its properties may be bound or
affected, (b) conflict with or result in a breach of any of the terms,
conditions or provisions of any order, judgment, decree, or ruling of any court,
arbitrator or Governmental Authority applicable to any Loan Party, or (c)
violate any provision of any statute or other rule or regulation of any
Governmental Authority applicable to any Loan Party, which default or violation,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

         SECTION 5.6 CONDITIONS OF AND TITLE TO PROPERTY; LEASES. Except as
disclosed on SCHEDULE 5.6, each Loan Party has good and sufficient title to or a
valid leasehold interest in all of its Material properties, including all such
properties reflected in the most recent balance sheet of the Borrower delivered

the ordinary course of business), in each case free and clear of all Liens,
except for Permitted Liens.

         SECTION 5.7 LITIGATION. Except as disclosed on SCHEDULE 5.7, there are
no actions, suits, proceedings or governmental investigations pending or, to
each Loan Party's knowledge, threatened against any Loan Party, in any court or
before any arbitrator of any kind or before any Governmental Authority, which,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect, or which purport to affect the rights and remedies of
the Administrative Agent, the Lenders, or the Issuing Bank pursuant to this
Agreement and the other Loan Documents or which purport to restrain or enjoin
(either temporarily, preliminarily or permanently) the performance by any Loan
Party of any action contemplated by any of the Loan Documents.

         SECTION 5.8 TAX RETURNS. Except as disclosed on SCHEDULE 5.8, each Loan
Party has filed all returns and reports that are required to be filed by it in
connection with any federal, state or local tax, duty or charge levied, assessed
or imposed upon it or its property or withheld by it, including unemployment,
social security and similar taxes and all of such taxes, have been either paid
or adequate reserves or other provision for the payment thereof have been made
in accordance with GAAP, except for any non-filing of returns or reports or any
non-payment of taxes or assessments that could not individually or in the
aggregate reasonably be expected to have a Material Adverse Effect.

Party, each employee benefit plan as to which any Loan Party may have any
liability complies in all material respects with all applicable provisions of
ERISA, including minimum funding requirements, and (a) no Prohibited Transaction
(as defined under ERISA) has occurred with respect to any such plan, (b) no
Reportable Event (as defined under Section 4043 of ERISA) has occurred with
respect to any such plan which would cause the Pension Benefit Guaranty
Corporation to institute proceedings under Section 4042 of ERISA, (c) the
Borrower has not withdrawn from any such plan or initiated steps to do so, and
(d) no steps have been taken to terminate any such plan.

         SECTION 5.10 ENVIRONMENTAL MATTERS. Except as disclosed on SCHEDULE
5.10, each Loan Party is (or, in respect of prior owned or operated real
property, was) in compliance, in all material respects, with all Environmental
Laws, including, without limitation, all Environmental Laws in jurisdictions in
which such Loan Party owns or operates, or had owned or operated, a

                                       24

facility or site, stores or has stored Collateral, arranges or has arranged for

knowledge, threatened against any Loan Party, any real property which any Loan
Party holds or has held an interest or any past or present operation of any Loan
Party that could reasonably be expected to result in a Material Adverse Effect.
To each Loan Party's knowledge, no release, threatened release or disposal of
hazardous waste, solid waste or other wastes is occurring, or to each Loan
Party's knowledge has occurred, on, under or to any real property in which any
Loan Party holds any interest or performs any of its operations, in violation of
any Environmental Law that could reasonably be expected to result in a Material
Adverse Effect. As used in this Section, "LITIGATION OR PROCEEDING" means any
demand, claim notice, suit, suit in equity, action, administrative action,
investigation or inquiry whether brought by a Governmental Authority or other
person; "ENVIRONMENTAL LAWS" means all provisions of laws, statutes, ordinances,
rules, regulations, permits, licenses, judgments, writs, injunctions, decrees,
orders, awards and standards promulgated by any Governmental Authority
concerning health, safety and protection of, or regulation of the discharge of
substances into, the environment; and the terms "REAL PROPERTY," "FACILITY" and

facility or site actually or previously leased by any Loan Party.

do not own any patents, trademarks or copyrights.

         SECTION 5.12 USE OF PROCEEDS; MARGIN REGULATIONS. The Borrower will use
the proceeds of the Loan only for lawful purposes in accordance with the terms
of this Loan Agreement. No part of the proceeds of the Loan will be used
directly or indirectly for the purpose of "PURCHASING" or "CARRYING" any "MARGIN
STOCK" within the respective meanings of each of the quoted terms under
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time in effect or for any purpose which violates the provisions of
the Regulations of such Board of Governors.

         SECTION 5.13 SOLVENCY. As of the date hereof and after giving effect to
the transactions contemplated by the Loan Documents, the Borrower will have
sufficient cash flow to enable it to generally pay its debts as and when they
mature and will not have an unreasonably small amount of capital relative to the

         SECTION 5.14 FULL DISCLOSURE. None of the Loan Documents contains any
untrue statement of material fact or omits to state a material fact necessary in
order to make the statements contained in this Agreement or the Loan Documents,
taken as a whole, not

                                       25

<PAGE>

misleading. There is no fact known to the Borrower which, individually or in the
aggregate with other facts known to the Borrower, could reasonably be expected
to have a Material Adverse Effect, and which has not otherwise been fully set
forth in this Agreement, the Addendum, the Schedules hereto or in the Loan
Documents. Each of the certificates delivered or to be delivered by each Loan
Party or any of its officers pursuant to the terms of the Loan Documents will be
true, accurate and complete in all material respects as of the date made.

         SECTION 5.15 COMPLIANCE WITH LAWS. Each Loan Party has duly complied
with, and its properties, business operations and leaseholds are in compliance
in all material respects with all Governmental Rules applicable to it, its
properties and the conduct of its business, except where the failure to comply
will not have a Material Adverse Effect.

SECTION 6. AFFIRMATIVE COVENANTS.

         The Borrower will comply with the covenants and agreements set forth in
this Section 6 from the date of execution of this Agreement unless and until all
Obligations have been fully paid and any commitments of the Administrative
Agent, the Lenders and the Issuing Bank to the Borrower have been terminated.

         SECTION 6.1 BOOKS AND RECORDS. The Borrower will maintain and will
cause its Subsidiaries to maintain accurate and complete books and records. The
Borrower will give and will cause its Subsidiaries to give representatives of
the Administrative Agent (who may be accompanied by representatives of the
Lenders) access, upon request and during normal business hours and in accordance
with the provisions of this Section 6.1, to books and records of account,
including permission to examine, copy and make abstracts from any of such books
and records and such other information as the Administrative Agent may from time
to time reasonably request, and the Borrower will make available to the
Administrative Agent, and will cause its Subsidiaries to make available to the
Administrative Agent, during normal business hours and in accordance with the
provisions of this Section 6.1, for examination copies of any reports,
statements or returns which the Borrower or any of its Subsidiaries may make to
or file with any governmental department, bureau or agency, federal or state. So
long as an Event of Default does not exist, the Administrative Agent will give
reasonable written notice at least one (1) Business Day prior to conducting any
examination under the preceding sentence and shall not conduct such examinations
at Borrower's expense more than once in any calendar year. Administrative Agent
agrees that it will conduct such review in a manner so as not to unreasonably
interfere with Borrower's business. Except as permitted under Section 10.7
hereof in connection with an assignment or grant of a participation interest in
the Loan, the Administrative Agent, the Lenders and the Issuing Bank will treat
as confidential all non-public information contained in such books and records;
provided, however, that if the Administrative Agent, the Lenders or the Issuing
Bank is required to disclose confidential information pursuant to a court order,
subpoena or similar process, prior to disclosure the Administrative Agent, the
Lenders and the Issuing Bank will: (a) promptly provide the Borrower with a copy
of the court order or subpoena; (b) cooperate with the Borrower at the
Borrower's expense in obtaining a protective or similar order; and (c) in any
event, disclose only such confidential information as the Administrative Agent,
the Lenders and the Issuing Bank, with the advice of its counsel, shall deem
necessary to comply with such court order or subpoena.

or made other adequate provision with respect thereto acceptable to the
Administrative Agent in its reasonable discretion; provided, however, that they
need not pay any such tax or assessment or claims if the nonpayment of all such
taxes and assessments and claims in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

         SECTION 6.6 MAINTENANCE OF EXISTENCE, OPERATION AND ASSETS. The
Borrower will and will cause its Subsidiaries to do all things reasonably
necessary to maintain, renew and keep in full force and effect their
organizational existence and all rights, permits and franchises necessary to
enable them to continue their business; continue in operation in substantially
the same manner as at present; keep their properties in good operating condition
and repair subject to normal wear and tear; and will make all reasonably
necessary and proper repairs, renewals, replacements, additions and improvements
thereto; provided that nothing in this Section 6.6 shall prevent the Borrower or
any of its subsidiaries from discontinuing the operations and maintenance of any
of their properties if such discontinuance is, in the judgment of the Borrower

expressly set forth in this Agreement) under or in connection with this
Agreement or any other instrument or document in connection herewith except for
gross negligence or willful misconduct. Without limiting the foregoing, neither

taken in good faith, in accordance with advice given by counsel. The
Administrative Agent may employ agents and attorneys-in-fact and shall not be
liable for the default or misconduct of any such Administrative agents or
attorneys-in-fact selected by the Administrative Agent with reasonable care. The
Administrative Agent shall not be bound to ascertain or inquire as to the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any of the other Loan Documents on the part of the Borrower or any
other party thereto.

         SECTION 9.4 ACTION ON INSTRUCTIONS. The Administrative Agent shall be
required to act and shall be fully protected in so acting and shall be entitled
to refrain from acting, and shall be fully protected in refraining from so
acting, under this Agreement, the Notes, the other Loan Documents or any other
instrument or document executed or delivered in connection herewith or
therewith, in accordance with written instructions from the Required Lenders or,
in the case of the matters set forth in items (a) through (g) of Section 10.2,
from all of the Lenders.

         SECTION 9.5 INDEMNIFICATION. To the extent the Borrower does not
reimburse and save harmless the Administrative Agent according to the terms
hereof for and from all costs, expenses and disbursements in connection
herewith, such costs, expenses and disbursements shall be borne by the Lenders
ratably in accordance with their respective Commitment Percentages. Each Lender
hereby agrees on such basis (i) to reimburse the Administrative Agent for such
Lender's pro rata share of all such reasonable costs, expenses and disbursements
on request and (ii) to the


                                       36

<PAGE>

extent of each such Lender's pro rata share, to indemnify and save harmless the
Administrative Agent against and from any and all losses, obligations,
penalties, actions, judgments and suits and other costs, expenses and
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against the Administrative Agent, other than as a consequence of
gross negligence or willful misconduct on the part of the Administrative Agent,
arising out of or in connection with (i) this Agreement, the Notes, the other
Loan Documents or any other agreement, instrument or document executed or
delivered in connection herewith or therewith, or (ii) any action taken at the
request of the Required Lenders or all of the Lenders hereunder, as the case may
be, including without limitation the reasonable costs, expenses and
disbursements in connection with defending themselves against any claim or
liability, or answering any subpoena or other process related to the exercise or
performance of any of their powers or duties under this Agreement, the other
Loan Documents, or any of the other agreements, instruments or documents
executed or delivered in connection herewith or the taking or refraining from
any action under or in connection with any of the foregoing.

         SECTION 9.6 ADMINISTRATIVE AGENT'S RIGHTS AS LENDER. With respect to
the Commitments of the Administrative Agent as Lenders hereunder, and any Loans
of the Administrative Agent under this Agreement, the other Loan Documents and
any other agreements, instruments and documents delivered pursuant hereto and
any other amounts due to the Administrative Agent under this Agreement, the
Administrative Agent shall have the same rights and powers, duties and
obligations under this Agreement, the Notes, the other Loan Documents or other
agreement, instrument or document as any Lender and may exercise such rights and
powers and shall perform such duties and fulfill such obligations as though it
were not an Administrative Agent hereunder. The Administrative Agent may accept
deposits from, lend money to, and generally engage, and continue to engage, in
any kind of business with the Borrower as if it were not an Administrative Agent
hereunder.

         SECTION 9.7 PAYMENT TO LENDERS. Promptly after receipt from the
Borrower of any principal repayment of the Loans, interest due on the Loans and
any Fees owing to the Lenders or other amounts due under any of the Loan
Documents (except for such amounts which are payable for the sole account of any
Lender or the Administrative Agent), the Administrative Agent shall distribute
to each Lender that Lender's share of the funds so received.

         SECTION 9.8 PRO RATA SHARING. All interest and principal payments on
the Loans and all Commitment Fees and Letter of Credit Fees are to be divided
pro rata among the Lenders in accordance with their respective Commitment
Percentages. Any sums obtained from the Borrower by any Lender by reason of the
exercise of its rights of set-off, banker's lien or in collection shall be
shared (net of costs) pro rata among the Lenders on the basis of the principal
amount of Loans outstanding. Nothing in this Section 9.8 shall be deemed to
require the sharing among the Lenders of collections specifically relating to,
or of the proceeds of any collateral securing, any other Indebtedness of the
Borrower to any Lender.

         SECTION 9.9 SUCCESSOR AGENT.

                  (a) RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative
Agent may resign as Administrative Agent hereunder by giving ninety (90) days
prior written notice to the Lenders and the Borrower. If such notice shall be
given, the Required Lenders shall appoint a


                                       37

<PAGE>

successor agent for the Lenders, during such ninety (90) day period, which
successor agent shall be reasonably satisfactory to the Borrower, to serve an
Administrative Agent hereunder and under the several Loan Documents. If at the
end of such ninety (90) day period, the Lenders have not appointed such a
successor, the resigning Administrative Agent shall use reasonable commercial
efforts to procure a successor reasonably satisfactory to the Lenders and the
Borrower, to serve as a successor agent for the Lenders hereunder and under the
several Loan Documents. Any such successor agent shall succeed to the rights,
powers and duties of the resigning Administrative Agent.

                           (b) RIGHTS OF THE FORMER ADMINISTRATIVE AGENT. Upon
the appointment of such successor agent or upon the expiration of such ninety
(90) day period (or any longer period to which the resigning Administrative
Agent has agreed), the resigning Administrative Agent's rights, powers and
duties hereunder shall be terminated, without any other or further act or deed
on the part of such former Administrative Agent or any of the parties to this
Agreement. After any resigning Administrative Agent's resignation hereunder as
an Administrative Agent hereunder, the provisions of this Section 9 shall inure
to the benefit of such retiring Administrative Agent as to any actions taken or
omitted to be taken by it while it was an Administrative Agent under this
Agreement.

SECTION 10. GENERAL PROVISIONS

         SECTION 10.1 SET-OFF. If the unpaid principal amount of the Notes,
interest accrued on the unpaid principal amount of the Notes or other amount
owing by the Borrower under this Agreement, the Notes or the other Loan
Documents shall have become due and payable (at maturity, by acceleration or
otherwise upon the occurrence of an Event of Default and during the continuance
thereof), each Lender will have the right, in addition to all other rights and
remedies available to it, to set-off against and to appropriate and apply to
such due and payable amounts any debt owing to, and any other funds held in any
manner for the account of, the Borrower by such Lender including, without
limitation, all funds in all deposit accounts (whether time or demand, general
or special, provisionally credited or finally credit, or otherwise) now or in
the future maintained by the Borrower with such Lender (but excluding in any
event accounts held by such Lender in a fiduciary capacity or as trustee, such
as Borrower's 401(k) Plan account). The Borrower consents to and confirms the
foregoing arrangements and confirms each Lender's right of banker's lien and
set-off. Nothing in this Agreement will be deemed a waiver or prohibition of or
restriction on each Lender's rights of banker's lien or set-off.

         SECTION 10.2 AMENDMENTS AND WAIVERS. Subject to the remaining
provisions of this Section 10.2, the Agent, the Lenders and the Borrower may,
from time to time, enter into amendments, extensions, renewals, modifications,
supplements and replacements to and of this Agreement, the Notes or the other
Loan Documents and the Lenders or the Required Lenders, as the case may be, may,
from time to time, waive compliance with a provision thereof. No amendment,
renewal, modification, extension, supplement, replacement or waiver of any
provision of the Agreement, the Notes or the other Loan Documents or consent to
any departure therefrom by the Borrower shall be effective unless it is in
writing and is signed by the Required Lenders (or the Administrative Agent with
the written consent of the Required Lenders), and then such waiver or consent
shall be effective only for the specific instance and for the specific purpose
for which it is given; provided, however, that no amendment, renewal,
modification,

                                       38

<PAGE>

waiver or consent, unless in writing and signed by all of the Lenders (or the
Administrative Agent with the written consent of all of the Lenders), shall do
any of the following:

                  (a) increase the Commitment of any Lender or subject any
Lender to any additional obligations hereunder;

                  (b) except for changes made pursuant to an Assignment and
Assumption Agreement, change any Lender's Commitment Percentage or the aggregate
or individual unpaid principal amount of the Notes, or forgive the payment of
the principal or interest payable on the Notes;

                  (c) waive an Event of Default in the payment of principal
and/or interest due hereunder and under any of the Notes;

                  (d) decrease the interest rate relating to the Loans;

                  (e) postpone any date fixed for any payment of principal of or
interest on the Loans, the Commitment Fee, the Letter of Credit Fee, or any
other obligations of the Borrower to the Lenders set forth in Section 2;

                  (f) reduce the Commitment Fee or the Letter of Credit Fee;

                  (g) amend the definition of the term "REQUIRED LENDERS",
"MAXIMUM AVAILABLE REVOLVING CREDIT LOAN AMOUNT" or "BORROWING BASE" as used
herein, or amend or waive the provisions of Section 2.2(a), 7.4(e), 9.8, 10.10
or this Section 10.2 hereof;

                  (h) release any Guarantor from its obligations pursuant to any
Guaranty Agreement;

                  (i) release any collateral securing the Obligations from the
security interest therein in favor of the Administrative Agent, for itself and
on behalf of the Lenders and the Issuing Bank; or

                  (j) amend or waive the provisions of this Section 10.2 in any
manner.

         Any such supplemental agreement shall apply equally to the Borrower and
each of the Lenders and shall be binding upon the Borrower, the Lenders, the
Administrative Agent and all future holders of the Notes. In the case of any
waiver, the Borrower, the Lenders and the Administrative Agent shall be restored
to their former positions and rights, and any Event of Default waived shall be
deemed to be cured and not continuing, but no such waiver shall extend to any
subsequent or other Event of Default, or impair any right consequent thereon.

         SECTION 10.3 TAXES. The Borrower shall pay any and all stamp, document,
transfer and recording taxes, filing fees and similar impositions payable or
hereafter reasonably determined by the Administrative Agent to be payable in
connection with this Agreement, the other Loan Documents and any other
documents, instruments and transactions pursuant to or in connection with any of
the Loan Documents other than for any tax which is measured on each Lender's net
income. The Borrower agrees to save the Lenders harmless from and against any
and all present

                                       39

<PAGE>

and future claims or liabilities with respect to, or resulting from, any delay
in paying or failure to pay any such taxes or similar impositions (other than
taxes or similar impositions remitted by the Borrower to a Lender and which such
Lender fails to pay in a timely or appropriate manner). The obligations of the
Borrower pursuant to this Section 10.3 shall survive the termination of this
Agreement and the repayment of the Obligations.

         SECTION 10.4 INCREASED COSTS. Within 30 calendar days following written
demand, together with the written evidence of the justification therefore
(including in reasonable detail, the calculation thereof), the Borrower will pay
to the Administrative Agent, all direct increased costs incurred and any losses
suffered or increased payments made by the Lenders as a consequence of making
the Loan by reason of any change in law or regulation or the interpretation of
any law or regulation imposing any reserve, deposit, allocation of capital or
similar requirement; provided that (i) each Lender shall take commercially
reasonable steps to mitigate or reduce amounts otherwise payable by the Borrower
and (ii) Borrower is not responsible for costs arising more than 90 days prior
to receipt of notice.

         SECTION 10.5 EXPENSES. The Borrower shall pay:

                  (a) All (A) out-of-pocket costs and expenses incurred by the
Administrative Agent in connection with the preparation, execution and delivery
of this Agreement, the other Loan Documents, and any and all other documents and
instruments prepared in connection herewith, including the Administrative
Agent's legal fees and expenses in connection therewith, and (B) reasonable
costs and expenses of the Administrative Agent (including but not limited to
reasonable fees and expenses of the Administrative Agent's counsel) in
connection with all amendments, waivers, consents and other documents and
instruments prepared or entered into from time to time in connection with this
Agreement and the other Loan Documents, after the Closing Date; and

                  (b) All reasonable costs and expenses of the Administrative
Agent, the Lenders and the Issuing Bank (including without limitation the
reasonable fees and disbursements of each such Person's counsel) in connection
with (A) the enforcement of this Agreement and the other Loan Documents arising
pursuant to a breach by Borrower of any of the terms, conditions,
representations, warranties or covenants of any Loan Document to which it is a
party including without limitation workouts and renegotiations; or (B) defending
or prosecuting any actions, suits or proceedings relating to any of the Loan
Documents.

         All of such costs and expenses shall be payable by the Borrower to the
Administrative Agent, upon demand or as otherwise agreed upon by the
Administrative Agent and the Lenders, and shall constitute Obligations under
this Agreement. The Borrower's obligations to pay such costs and expenses shall
survive the termination of this Agreement and the repayment of the Obligations.

         SECTION 10.6 NOTICES.

                  (a) NOTICE TO THE BORROWER. All notices required to be

         SECTION 10.7 ASSIGNMENTS AND PARTICIPATIONS.

                  (a) ASSIGNMENTS. Subject to the remaining provisions of this
Subsection 10.7(a), any Lender (a "TRANSFEROR LENDER"), at any time, in the
ordinary course of its commercial banking business and in accordance with
applicable law, may sell to one or more financial institutions (individually a
"PURCHASING LENDER"), a portion or all of its rights and obligations under this
Agreement and the Notes then held by it, pursuant to an Assignment and
Assumption Agreement substantially in the form of EXHIBIT H executed by the
Transferor Lender, such Purchasing Lender and the Administrative Agent; subject,
however to the following requirements:

                           (i) Each such assignment must be in a minimum amount
of $4,000,000, or, if in excess thereof, in integral multiples of $1,000,000,
unless the Transferor Lender's Commitment is less than $4,000,000, in which case
such assignment shall be in the full amount of the Transferor Lender's
Commitment;

                           (ii) The Borrower and the Administrative Agent shall
consent to each such assignment, which consent shall not be unreasonably
withheld or delayed; and

                           (iii) The Transferor Lender shall pay to the
Administrative Agent a $3,500 service fee for each such transfer at the time of
each such transfer;

provided, however, the restrictions set forth in item (i) above shall not apply
(x) in the case of an assignment by a Lender to an Affiliate of such Lender or
(y) in the case of any assignment by any Transferor Lender upon the occurrence
and during the continuation of an Event of Default; and provided, further, that
upon the occurrence and during the continuance of an Event of Default the
consent of the Borrower to any assignment shall not be required.

         Upon the execution, delivery, acceptance and recording of any such
Assignment and Assumption Agreement, from and after the Transfer Effective Date
determined pursuant to such Assignment and Assumption Agreement, all parties
hereto agree that (a) the Purchasing Lender thereunder shall be a party hereto
as a Lender and, to the extent provided in such Assignment and Assumption
Agreement, shall have the rights and obligations of a Lender hereunder with a
Commitment as set forth therein, and (b) the Transferor Lender thereunder shall,
to the extent provided in such Assignment and Assumption Agreement, be released
from its obligations as a Lender under this Agreement. Such Assignment and
Assumption Agreement shall be deemed to amend this Agreement (without further
action) to the extent, and only to the extent, necessary to reflect the addition
of such Purchasing Lender as a Lender and the resulting adjustment of Commitment
Percentages arising from the purchase by such Purchasing Lender of all or a
portion of the rights and obligations of such Transferor Lender under this
Agreement and its

                                       42

<PAGE>

Notes. On or prior to the Transfer Effective Date, the Borrower shall execute
and deliver to the Administrative Agent, in exchange for the surrendered Notes
held by the Transferor Lender, to the order of such Purchasing Lender in an
amount equal to the Commitment or the Loans assumed by it and purchased by it
pursuant to such Assignment and Assumption Agreement, and new Notes payable to
the order of the Transferor Lender in an amount equal to the Commitment or the
Loans retained by it hereunder.

         In addition to the assignments permitted above, any Lender may assign
and pledge all or any portion of its Loans and Notes to any Federal Reserve Bank
as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank. No such assignment shall release the assigning Lender from its obligations
and duties hereunder.

                  (b) ASSIGNMENT REGISTER. The Administrative Agent shall
maintain, at its address referred to in Subsection 10.6(b), a copy of each
Assignment and Assumption Agreement delivered to it and a register (the
"REGISTER") for the recordation of the names and addresses of the Lenders and
the amount of the Loans owing to each Lender from time to time. The entries in
the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register as the owner of the Loans recorded therein for
all purposes of this Agreement. The Register shall be available at the office of
the Administrative Agent set forth in Subsection 10.6(b) for inspection by
either the Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice.

                  (c) PARTICIPATIONS. Each Lender, in the ordinary course of its
commercial banking business and in accordance with applicable law, may sell to
one or more Participants a participating interest (in minimum amounts of
$4,000,000) in any Loan owing to such Lender, the interest of such Lender in any
Notes or the Commitment of such Lender. In the event of any such sale by a
Lender of a participating interest to a Participant, such Lender's obligations
under this Agreement to the other parties to this Agreement shall remain
unchanged, such Lender shall remain solely responsible for the performance
thereof, such Lender shall remain the holder of its Notes for all purposes under
this Agreement and the Borrower, the other Lenders and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement or its Notes. No
participation interest may be sold to a direct competitor of the Borrower.

         SECTION 10.8 WITHHOLDING OF INCOME TAXES. At least five (5) Business
Days prior to the first date on which interest or fees are payable hereunder for
the account of any Lender or Participant each Lender or Participant that is not
incorporated under the laws of the United States or a state thereof shall
deliver to the Borrower and the Administrative Agent two (2) duly completed
copies of United States Internal Revenue Service Form W-9, 4224 or 1001 or other
applicable form prescribed by the Internal Revenue Service. Such form shall
certify that such Lender or Participant is entitled to receive payments under
this Agreement and any applicable Note without deduction or withholding of any
United States Federal income taxes, or is subject to such tax at a reduced rate
under an applicable tax treaty or under United States Internal Revenue Service
Form W-8, or another applicable form or a certificate of such Lender or
Participant indicating that no such exemption or reduced rate is allowable with
respect to such

                                       43

<PAGE>

payments. Each Lender or Participant which delivers a Form W-8, W-9, 4224 or
1001 further undertakes to deliver to the Borrower and the Administrative Agent
two additional copies of such form (or a successor form) on or before the date
that such form expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form so delivered by it, and such
amendments thereto or extensions or renewals thereof as may be reasonably
required by the Borrower or the Administrative Agent, either certifying that
such Lender or Participant is entitled to receive payments under this Agreement
and the Notes without deduction or withholding of any United States Federal
income taxes or is subject to such tax at a reduced rate under an applicable tax
treaty or stating that no such exemption or reduced rate is allowable. The
Administrative Agent shall be entitled to withhold United States Federal income
taxes at the full withholding rate, unless the Lender or Participant establishes
an exemption, or at the applicable reduced rate, as established pursuant to the
provisions of this Section 10.8.

         SECTION 10.9 INDEMNITY. The Borrower hereby agrees to indemnify the
Administrative Agent, the Lenders and the Issuing Bank and each of their
respective directors, officers, employees, attorneys, agents and Affiliates
against, and hold each of them harmless from, any loss, liabilities, damages,
claims, costs and expenses (including reasonable attorneys' fees and
disbursements) suffered or incurred by any of them arising out of, resulting
from or in any manner connected with, the execution, delivery and performance of
each of the Loan Documents, the Loans, the Notes and any and all transactions
related to or consummated in connection with the Loans, including, without
limitation, losses, liabilities, damages, claims, costs and expenses suffered or
incurred by the Administrative Agent, the Lenders and the Issuing Bank or any of
their respective directors, officers, employees, attorneys, agents or Affiliates
arising out of or related to investigating, preparing for, defending against, or
providing evidence, producing documents or taking any other action in respect of
any commenced or threatened litigation, administrative proceeding or
investigation under any Federal Securities Law or any other Governmental Rule of
any jurisdiction, or at common law or otherwise, that is alleged to arise out of
or is based on (i) any untrue statement or alleged untrue statement of any
material fact of the Borrower or any Affiliate of the Borrower in any document
or schedule filed with the Securities and Exchange Commission or any other
Governmental Authority; (ii) any omission or alleged omission to state any
material fact required to be stated in such document or schedule, or necessary
to make the statements made therein, in light of the circumstances under which
made, not misleading; (iii) any actual or alleged acts, practices or omissions
of the Borrower or its directors, officers, partners, employees, attorneys,
agents or Affiliates related to the making of any acquisition, purchase of
shares or assets pursuant thereto, financing of such purchases or the
consummation of any other transactions contemplated by any such acquisitions
that are alleged to be in violation of any Federal securities law or of any
other statute, regulation or other law of any jurisdiction applicable to the
making of any such acquisition, the purchase of shares or assets pursuant
thereto, the financing of such purchases or the consummation of the other
transactions contemplated by any such acquisition; or (iv) any withdrawals,
termination or cancellation of any such proposed acquisition for any reason
whatsoever. Excluding, however, any claim arising due to the gross negligence or
willful misconduct of the indemnified party. The indemnity set forth in this
Section 10.9 shall be in addition to any other obligations or liabilities of the

upon the Borrower, the Administrative Agent, the Lenders, the Issuing Bank and
their respective successors and assigns, and shall inure to the benefit of the

agreements of the Borrower contained herein or in the other Loan Documents or

hereunder and so long thereafter until payment in full of the Loans, the Notes
and the Obligations is made.

         SECTION 10.14 PRESERVATION OF RIGHTS. No delay or omission on the part
of the Lenders to exercise any right or power arising hereunder will impair any
such right or power or be considered a waiver of any such right or power or any
acquiescence therein, nor will the action or inaction of the Lenders impair any
right or power arising hereunder. The Lenders' rights and remedies hereunder are
cumulative and not exclusive of any other rights or remedies which the Lenders
may have under other agreements, at law or in equity.

         SECTION 10.15 ILLEGALITY. In case any one or more of the provisions
contained in this Agreement should be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
contained herein shall not in any way be affected or impaired thereby.

         SECTION 10.16 CHANGES IN WRITING. No modification, amendment or waiver
of any provision of this Agreement nor consent to any departure by the Borrower
therefrom, will in any event be effective unless the same is in writing and
signed by the Lenders and, in the case of amendments and modifications, by the
Borrower, and then such waiver or consent shall be

                                       45

effective only in the specific instance and for the purpose for which given. No
notice to or demand on the Borrower in any case will entitle the Borrower to any
other or further notice or demand in the same, similar or other circumstance.

this Agreement are included for convenience of reference only and shall not

payment(s) had not been made) if at any time any amount received by the Lenders

refunded or returned by the Lenders to the Borrower or any other person or
entity (i) upon or as a result of the insolvency, bankruptcy, dissolution,
liquidation or reorganization of the Borrower or (ii) upon or as a result of the
