Lenders to changes in interest rates), declare that (i) each Eurodollar Advance

rate otherwise applicable to such Interest Period plus 2% per annum and (ii)
each Floating Rate Advance shall bear interest at a rate per annum equal to the
Floating Rate in effect from time to time plus 2% per annum, provided that,

and each Lender's share thereof.

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

          (iv)  Any Lender may request that its Loans be evidenced by a
promissory note (a "Note"). In such event, the Borrower shall prepare, execute
and deliver to such Lender a Note payable to the order of such Lender in a form
supplied by the Agent. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after any assignment

                                       15
<PAGE>   21

pursuant to Section 12.3) be represented by one or more Notes payable to the
order of the payee named therein or any assignee pursuant to Section 12.3,
except to the extent that any such Lender or assignee subsequently returns any
such Note for cancellation and requests that such Loans once again be evidenced
as described in paragraphs (i) and (ii) above.

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

          1.15  Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the date hereof, on any date on which
the Floating Rate Advance is prepaid, whether due to acceleration or otherwise,
and at maturity. Interest accrued on that portion of the outstanding principal
amount of any Floating Rate Advance converted into a Eurodollar Advance on a day
other than a Payment Date shall be payable on the date of conversion. Interest
accrued on each Eurodollar Advance shall be payable on the last day of its
applicable Interest Period, on any date on which the Eurodollar Advance is
prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued
on each Eurodollar Advance having an Interest Period longer than three months
shall also be payable on the last day of each three-month interval during such
Interest Period. Interest and fees shall be calculated for actual days elapsed
on the basis of a 360-day year. Interest shall be payable for the day an Advance
is made but not for the day of any payment on the amount paid if payment is
received prior to noon (local time) at the place of payment. If any payment of
principal of or interest on an Advance shall become due on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day
and, in the case of a principal payment, such extension of time shall be
included in computing interest in connection with such payment.

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

                                       16
<PAGE>   22

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

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

          1.19  Extension of Facility Termination Date. The Borrower may request
an extension of the Facility Termination Date by submitting a request for an
extension to the Agent (an "Extension Request") no more than 60 days or less
than 45 days prior to the Facility Termination Date. The Extension Request must
specify the new Facility Termination Date requested by the Borrower and the date
(which must be at least 15 days after the Extension Request is delivered to the
Agent) as of which the Lenders must respond to the Extension Request (the
"Response Date"). The new Facility Termination Date shall be no more than 364
days after the Facility Termination Date in effect at the time the Extension
Request is received, including the Facility Termination Date as one of the days
in the calculation of the days elapsed. Promptly upon receipt of an Extension
Request, the Agent shall notify each Lender of the contents thereof and shall
request each Lender to approve the Extension Request. Each Lender approving the
Extension Request shall deliver its written consent no later than the Response
Date. If the consent of each of the Lenders is received by the Agent, the
Facility Termination Date specified in the Extension Request shall become
effective on the existing Facility Termination Date and the Agent shall promptly
notify the Borrower and each Lender of the new Facility Termination Date. If the
consent of each of the Lenders is not so received, the Facility Termination Date
shall not be so extended.

                                       17

          1.20  Replacement of Lender. If any Lender's obligation to make or
continue, or to convert Floating Rate Advances into, Eurodollar Advances shall
be suspended pursuant to Section 3.3 (any Lender so affected an "Affected
Lender"), the Borrower may elect, if such amounts continue to be charged or such
suspension is still effective, to replace such Affected Lender as a Lender party
to this Agreement, provided that no Default or Unmatured Default shall have
occurred and be continuing at the time of such replacement, and provided further
that, concurrently with such replacement, (i) another bank or other entity which
is reasonably satisfactory to the Borrower and the Agent shall agree, as of such
date, to purchase for cash the Advances and other Obligations due to the
Affected Lender pursuant to an assignment substantially in the form of Exhibit C
and to become a Lender for all purposes under this Agreement and to assume all
obligations of the Affected Lender to be terminated as of such date and to
comply with the requirements of Section 12.3 applicable to assignments, and (ii)
the Borrower shall pay to such Affected Lender in same day funds on the day of
such replacement (A) all interest, fees and other amounts then accrued but
unpaid to such Affected Lender by the Borrower hereunder to and including the
date of termination, including without limitation payments due to such Affected
Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the
payment which would have been due to such Lender on the day of such replacement
under Section 3.4 had the Loans of such Affected Lender been prepaid on such
date rather than sold to the replacement Lender.

                                   ARTICLE III

                             YIELD PROTECTION; TAXES

          1.21  Yield Protection. If, on or after the date of this Agreement,
the adoption of any law or any governmental or quasi-governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law), or any change in the interpretation or administration thereof by any
governmental or quasi-governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
Lender or applicable Lending Installation with any request or directive (whether
or not having the force of law) of any such authority, central bank or
comparable agency:

          (1)   subjects any Lender or any applicable Lending Installation to
                any Taxes, or changes the basis of taxation of payments (other
                than with respect to Excluded Taxes) to any Lender in respect of
                its Eurodollar Loans, or

          (2)   imposes or increases or deems applicable any reserve,
                assessment, insurance charge, special deposit or similar
                requirement against assets of, deposits with or for the account
                of, or credit extended by, any Lender or any applicable Lending

                                       18
<PAGE>   24

                Installation (other than reserves and assessments taken into
                account in determining the interest rate applicable to
                Eurodollar Advances), or

          (3)   imposes any other condition the result of which is to increase
                the cost to any Lender or any applicable Lending Installation of
                making, funding or maintaining its Eurodollar Loans or reduces
                any amount receivable by any Lender or any applicable Lending
                Installation in connection with its Eurodollar Loans, or
                requires any Lender or any applicable Lending Installation to
                make any payment calculated by reference to the amount of
                Eurodollar Loans held or interest received by it, by an amount
                deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Eurodollar Loans or
Commitment or to reduce the return received by such Lender or applicable Lending
Installation in connection with such Eurodollar Loans or Commitment, then,
within 15 days of demand by such Lender, the Borrower shall pay such Lender such
additional amount or amounts as will compensate such Lender for such increased
cost or reduction in amount received.

          1.22  Changes in Capital Adequacy Regulations. If a Lender determines
the amount of capital required or expected to be maintained by such Lender, any
Lending Installation of such Lender or any corporation controlling such Lender
is increased as a result of a Change, then, within 15 days of demand by such
Lender, the Borrower shall pay such Lender the amount necessary to compensate
for any shortfall in the rate of return on the portion of such increased capital
which such Lender determines is attributable to this Agreement, its Loans or its
Commitment to make Loans hereunder (after taking into account such Lender's
policies as to capital adequacy). "Change" means (i) any change after the date
of this Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of
or change in any other law, governmental or quasi-governmental rule, regulation,
policy, guideline, interpretation, or directive (whether or not having the force
of law) after the date of this Agreement which affects the amount of capital
required or expected to be maintained by any Lender or any Lending Installation
or any corporation controlling any Lender. "Risk-Based Capital Guidelines" means
(i) the risk-based capital guidelines in effect in the United States on the date
of this Agreement, including transition rules, and (ii) the corresponding
capital regulations promulgated by regulatory authorities outside the United
States implementing the July 1988 report of the Basle Committee on Banking
Regulation and Supervisory Practices Entitled "International Convergence of
Capital Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.

          1.23  Availability of Types of Advances. If any Lender determines that
maintenance of its Eurodollar Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders

                                       19
<PAGE>   25

reasonably determine that (i) deposits of a type and maturity appropriate to
match fund Eurodollar Advances are not available or (ii) the interest rate
applicable to Eurodollar Advances does not accurately reflect the cost of making
or maintaining Eurodollar Advances, then the Agent shall suspend the
availability of Eurodollar Advances (other than for a reason applicable to a
particular Lender only and not to the market in general) and require any
affected Eurodollar Advances to be repaid or converted to Floating Rate
Advances, subject to the payment of any funding indemnification amounts required
by Section 3.4.

          1.24  Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by the Lenders, the Borrower will indemnify each Lender for any
loss or cost incurred by it resulting therefrom, including, without limitation,
any loss or cost in liquidating or employing deposits acquired to fund or
maintain such Eurodollar Advance.

          1.25  Taxes. (i) All payments by the Borrower to or for the account of
any Lender or the Agent hereunder or under any Note shall be made free and clear
of and without deduction for any and all Taxes. If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender or the Agent, (a) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.5) such Lender or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (b) the Borrower shall make such
deductions, (c) the Borrower shall pay the full amount deducted to the relevant
authority in accordance with applicable law and (d) the Borrower shall furnish
to the Agent the original copy of a receipt evidencing payment thereof within 30
days after such payment is made.

          (ii)  In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note ("Other Taxes").

          (iii) The Borrower hereby agrees to indemnify the Agent and each
Lender for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed on amounts payable under this
Section 3.5) paid by the Agent or such Lender and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto.
Payments due under this indemnification shall be made within 30 days of the date
the Agent or such Lender makes demand therefor pursuant to Section 3.6.

                                       20
<PAGE>   26

          (iv)  If the U.S. Internal Revenue Service or any other governmental
authority of the United States or any other country or any political subdivision
thereof asserts a claim that the Agent did not properly withhold tax from
amounts paid to or for the account of any Lender (because the appropriate form
was not delivered or properly completed, because such Lender failed to notify
the Agent of a change in circumstances which rendered its exemption from
withholding ineffective, or for any other reason), such Lender shall indemnify
the Agent fully for all amounts paid, directly or indirectly, by the Agent as
tax, withholding therefor, or otherwise, including penalties and interest, and
including taxes imposed by any jurisdiction on amounts payable to the Agent
under this subsection, together with all costs and expenses related thereto
(including attorneys fees and time charges of attorneys for the Agent, which
attorneys may be employees of the Agent). The obligations of the Lenders under
this Section 3.5(iv) shall survive the payment of the Obligations and
termination of this Agreement.

          1.26  Lender Statements; Survival of Indemnity. To the extent
reasonably possible, each Lender shall designate an alternate Lending
Installation with respect to its Eurodollar Loans to reduce any liability of the
Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the
unavailability of Eurodollar Advances under Section 3.3, so long as such
designation is not, in the judgment of such Lender, disadvantageous to such
Lender. Each Lender shall deliver a written statement of such Lender to the
Borrower (with a copy to the Agent) as to the amount due, if any, under Section
3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable
detail the calculations upon which such Lender determined such amount and shall
be final, conclusive and binding on the Borrower in the absence of manifest
error. Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such written statement. The
obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive
payment of the Obligations and termination of this Agreement.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

          1.27  Initial Advance. The Lenders shall not be required to make the
initial Advance hereunder unless the Borrower has furnished to the Agent with
sufficient copies for the Lenders:

          (1)   Copies of the articles of incorporation of the Borrower,
                together with all amendments, and a certificate of existence,
                each certified by the appropriate governmental officer in its
                jurisdiction of incorporation.

<PAGE>   27

          (2)   Copies, certified by the Secretary or Assistant Secretary of the
                Borrower, of its by-laws and of its Board of Directors'

                authorizing the execution of the Loan Documents to which the
                Borrower is a party.

          (3)   An incumbency certificate, executed by the Secretary or
                Assistant Secretary of the Borrower, which shall identify by
                name and title and bear the signatures of the Authorized
                Officers and any other officers of the Borrower authorized to
                sign the Loan Documents to which the Borrower is a party, upon
                which certificate the Agent and the Lenders shall be entitled to
                rely until informed of any change in writing by the Borrower.

          (4)   A certificate, signed by the treasurer of the Borrower, stating
                that on the initial Borrowing Date no Default or Unmatured
                Default has occurred and is continuing.

          (5)   A written opinion of the Borrower's counsel, addressed to the
                Lenders in substantially the form of Exhibit A.

          (6)   Any Notes requested by a Lender pursuant to Section 2.13 payable
                to the order of each such requesting Lender.

          (7)   Written money transfer instructions, in substantially the form
                of Exhibit D, addressed to the Agent and signed by an Authorized
                Officer, together with such other related money transfer
                authorizations as the Agent may have reasonably requested.

          (8)   Such other documents as any Lender or its counsel may have
                reasonably requested.

          1.28  Each Advance. The Lenders shall not be required to make any
Advance unless on the applicable Borrowing Date:

          (1)   There exists no Default or Unmatured Default.

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

                                       22
<PAGE>   28

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

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

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

          The Borrower represents and warrants to the Lenders that:

          1.29  Existence and Standing. Each of the Borrower and its
Subsidiaries is a corporation, partnership (in the case of Subsidiaries only) or
limited liability company duly and properly incorporated or organized, as the
case may be, validly existing and (to the extent such concept applies to such
entity) in good standing under the laws of its jurisdiction of incorporation or
organization and has all requisite authority to conduct its business in each
jurisdiction in which its business is conducted.

          1.30  Authorization and Validity. The Borrower has the power and
authority and legal right to execute and deliver the Loan Documents and to
perform its obligations thereunder. The execution and delivery by the Borrower
of the Loan Documents and the performance of its obligations thereunder have
been duly authorized by proper corporate proceedings, and the Loan Documents to
which the Borrower is a party constitute legal, valid and binding obligations of
the Borrower enforceable against the Borrower in accordance with their terms,
except as enforceability may be limited by bankruptcy, insolvency or similar
laws affecting the enforcement of creditors' rights generally.

          1.31  No Conflict; Government Consent. Neither the execution and
delivery by the Borrower of the Loan Documents, nor the consummation of the
transactions therein contemplated, nor compliance with the provisions thereof
will violate (i) any law, rule, regulation, order, writ, judgment, injunction,
decree or award binding on the Borrower or any of its Subsidiaries or (ii) the
Borrower's articles or certificate of incorporation or by-laws, or (iii) the
provisions of any indenture, instrument or agreement to which the Borrower or
any of its Subsidiaries is a party or is subject, or by which it, or its
Property, is bound, or conflict with or constitute a default thereunder, or
result in, or require, the creation or imposition of any Lien in, of or on the
Property of the Borrower or a Subsidiary pursuant to the terms of any such
indenture, instrument or agreement. No order, consent, adjudication, approval,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, or other

                                       23
<PAGE>   29

action in respect of any governmental or public body or authority, or any
subdivision thereof, which has not been obtained by the Borrower, is required to
be obtained by the Borrower in connection with the execution and delivery of the
Loan Documents, the borrowings under this Agreement, the payment and performance
by the Borrower of the Obligations or the legality, validity, binding effect or
enforceability of any of the Loan Documents.

          1.32  Financial Statements. The December 31, 1999 consolidated
financial statements of the Borrower and its Subsidiaries included in the
Borrower's Annual Report on Form 10-K for the year December 31, 1999 and
heretofore delivered to the Lenders were prepared in accordance with generally
accepted accounting principles in effect on the date such statements were
prepared and fairly present the consolidated financial condition and operations
of the Borrower and its Subsidiaries at such date and the consolidated results
of their operations for the period then ended.

          1.33  Material Adverse Change. Since December 31, 1999 there has been
no change in the business, Property, prospects, condition (financial or
otherwise) or results of operations of the Borrower and its Subsidiaries which
could reasonably be expected to have a Material Adverse Effect.

          1.34  Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due pursuant to said returns or pursuant to any
assessment received by the Borrower or any of its Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided in accordance with Agreement Accounting Principles
and as to which no Lien exists. No tax liens have been filed and no claims are
being asserted with respect to any such taxes. The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of any
taxes or other governmental charges are adequate.

          1.35  Litigation and Contingent Obligations. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting the
Borrower or any of its Subsidiaries which could reasonably be expected to have a
Material Adverse Effect or which seeks to prevent, enjoin or delay the making of
any Loans. Other than any liability incident to any litigation, arbitration or
proceeding which could not reasonably be expected to have a Material Adverse
Effect, the Borrower has no material contingent obligations not provided for or
disclosed in the financial statements referred to in Section 5.4.

          1.36  Subsidiaries. Schedule 1 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital

                                       24
<PAGE>   30

stock or other ownership interests of such Subsidiaries have been (to the extent
such concepts are relevant with respect to such ownership interests) duly
authorized and issued and are fully paid and non-assessable.

          1.37  ERISA. The Unfunded Liabilities of all Single Employer Plans do
not in the aggregate exceed $3,000,000. Neither the Borrower nor any other
member of the Controlled Group has incurred, or is reasonably expected to incur,
any withdrawal liability to Multiemployer Plans in excess of $3,000,000 in the
aggregate. Each Plan complies in all material respects with all applicable
requirements of law and regulations, no Reportable Event has occurred with
respect to any Plan, neither the Borrower nor any other member of the Controlled
Group has withdrawn from any Plan or initiated steps to do so, and no steps have
been taken to reorganize or terminate any Plan.

          1.38  Accuracy of Information. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or to any
Lender in connection with the negotiation of, or compliance with, the Loan
Documents contained any material misstatement of fact or omitted to state a
material fact or any fact necessary to make the statements contained therein not
misleading.

          1.39  Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder.

          1.40  Material Agreements. Neither the Borrower nor any Subsidiary is
a party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Indebtedness.

          1.41  Compliance With Laws. The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property except for any failure
to comply with any of the foregoing which could not reasonably be expected to
have a Material Adverse Effect.

          1.42  Ownership of Properties. Except as set forth on Schedule 2, on
the date of this Agreement, the Borrower and its Subsidiaries will have good
title, free of all Liens other than those permitted by Section 6.15, to all of

                                       25
<PAGE>   31

recent consolidated financial statements provided to the Agent as owned by the
Borrower and its Subsidiaries.

          1.43  Plan Assets; Prohibited Transactions. Neither the execution of
this Agreement nor the making or holding of Loans hereunder gives rise to a
prohibited transaction within the meaning of Section 406 of ERISA or Section
4975 of the Code.

          1.44  Environmental Matters. In the ordinary course of its business,
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or are the subject of
any federal or state investigation evaluating whether any remedial action is
needed to respond to a release of any toxic or hazardous waste or substance into
the environment, which non-compliance or remedial action could reasonably be
expected to have a Material Adverse Effect.

          1.45  Investment Company Act. Neither the Borrower nor any Subsidiary

company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

of post-retirement medical and insurance benefits payable by the Borrower and
its Subsidiaries to its employees and former employees, as estimated by the
Borrower in accordance with procedures and assumptions deemed reasonable by the
Required Lenders, does not exceed $3,000,000.

                Subsidiary, as applicable, has taken and proposes to take with

                such fourteen day period;

increased over the amounts contributed to such Multiemployer Plans for the
respective plan years of each such Multiemployer Plan immediately preceding the
plan year in which the reorganization or termination occurs by an amount
exceeding $3,000,000.

          1.77  The Borrower or any of its Subsidiaries shall (i) be the subject
of any proceeding or investigation pertaining to the release by the Borrower,
any of its Subsidiaries or any other Person of any toxic or hazardous waste or
substance into the environment, or (ii) violate any Environmental Law, which, in
the case of an event described in clause (i) or clause (ii), could reasonably be
expected to have a Material Adverse Effect.

          1.78  Any Change in Control shall occur.

          1.79  Nonpayment by the Borrower of any Rate Hedging Obligation when
due or the breach by the Borrower of any term, provision or condition contained

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

          1.81  Acceleration. If any Default described in Section 7.6 or 7.7
occurs with respect to the Borrower, the obligations of the Lenders to make
Loans hereunder shall automatically terminate and the Obligations shall
immediately become due and payable without any election or action on the part of
the Agent or any Lender. If any other Default occurs, the Required Lenders (or
the Agent with the consent of the Required Lenders) may terminate or suspend the
obligations of the Lenders to make Loans hereunder, or declare the Obligations
to be due and payable, or both, whereupon the Obligations shall become
immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which the Borrower hereby expressly waives.

                                       34
<PAGE>   40

          If, within 30 days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
Section 7.6 or 7.7 with respect to the Borrower) and before any judgment or
decree for the payment of the Obligations due shall have been obtained or
entered, the Required Lenders (in their sole discretion) shall so direct, the
Agent shall, by notice to the Borrower, rescind and annul such acceleration
and/or termination.

          1.82  Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of all of the Lenders:

          (1)   Extend the final maturity of any Loan or forgive all or any
                portion of the principal amount thereof, or reduce the rate or
                extend the time of payment of interest or fees thereon.

          (2)   Reduce the percentage specified in the definition of Required
                Lenders.

          (3)   Extend the Facility Termination Date, or reduce the amount or
                extend the payment date for, the mandatory payments required
                under Section 2.2, or increase the amount of the Commitment of
                any Lender hereunder, or permit the Borrower to assign its
                rights under this Agreement.

          (4)   Amend this Section 8.2.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent. The Agent may waive payment
of the fee required under Section 12.3.2 without obtaining the consent of any
other party to this Agreement.

          1.83  Preservation of Rights. No delay or omission of the Lenders or
the Agent to exercise any right under the Loan Documents shall impair such right
or be construed to be a waiver of any Default or an acquiescence therein, and
the making of a Loan notwithstanding the existence of a Default or the inability
of the Borrower to satisfy the conditions precedent to such Loan shall not
constitute any waiver or acquiescence. Any single or partial exercise of any
such right shall not preclude other or further exercise thereof or the exercise
of any other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Loan Documents whatsoever shall be valid unless
in writing signed by the Lenders required pursuant to Section 8.2, and then only
to the extent in such writing specifically set forth. All remedies

                                       35
<PAGE>   41

contained in the Loan Documents or by law afforded shall be cumulative and all
shall be available to the Agent and the Lenders until the Obligations have been
paid in full.

                                   ARTICLE IX

                               GENERAL PROVISIONS

          1.84  Survival of Representations. All representations and warranties
of the Borrower contained in this Agreement shall survive the making of the
Loans herein contemplated.

          1.85  Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, no Lender shall be obligated to extend credit to
the Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

          1.86  Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

          1.87  Entire Agreement. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent and the Lenders and supersede
all prior agreements and understandings among the Borrower, the Agent and the
Lenders relating to the subject matter thereof.

          1.88  Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns, provided, however, that the parties
hereto expressly agree that the Arranger shall enjoy the benefits of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth
therein and shall have the right to enforce such provisions on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

          1.89  Expenses; Indemnification. (i) The Borrower shall reimburse the
Agent and the Arranger for any costs, internal charges and out-of-pocket
expenses (including attorneys' fees and time charges of attorneys for the Agent,
which attorneys may be employees of the Agent) paid or incurred by the Agent or
the Arranger in connection with the preparation, negotiation, execution,
delivery, syndication, review, amendment, modification, and administration of
the Loan Documents. The Borrower also agrees to reimburse the Agent, the
Arranger and the Lenders for any costs, internal charges and out-of-pocket
expenses (including attorneys' fees and time charges

                                       36
<PAGE>   42

of attorneys for the Agent, the Arranger and the Lenders, which attorneys may be
employees of the Agent, the Arranger or the Lenders) paid or incurred by the
Agent, the Arranger or any Lender in connection with the collection and
enforcement of the Loan Documents.

          (ii)  The Borrower hereby further agrees to indemnify the Agent, the
Arranger and each Lender, its directors, officers and employees against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all expenses of litigation or preparation
therefor whether or not the Agent, the Arranger or any Lender is a party
thereto) which any of them may pay or incur arising out of or relating to this
Agreement, the other Loan Documents, the transactions contemplated hereby or the
direct or indirect application or proposed application of the proceeds of any
Loan hereunder except to the extent that they are determined in a final
non-appealable judgment by a court of competent jurisdiction to have resulted
from the gross negligence or willful misconduct of the party seeking
indemnification. The obligations of the Borrower under this Section 9.6 shall
survive the termination of this Agreement.

          1.90  Numbers of Documents. All statements, notices, closing
documents, and requests hereunder shall be furnished to the Agent with
sufficient counterparts so that the Agent may furnish one to each of the
Lenders.

          1.91  Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

          1.92  Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

          1.93  Nonliability of Lenders. The relationship between the Borrower
on the one hand and the Lenders and the Agent on the other hand shall be solely
that of borrower and lender. Neither the Agent, the Arranger nor any Lender
shall have any fiduciary responsibilities to the Borrower. Neither the Agent,
the Arranger nor any Lender undertakes any responsibility to the Borrower to
review or inform the Borrower of any matter in connection with any phase of the
Borrower's business or operations. The Borrower agrees that neither the Agent,
the Arranger nor any Lender shall have liability to the Borrower (whether
sounding in tort, contract or otherwise) for losses suffered by the Borrower in
connection with, arising out of, or in any way related to, the transactions
contemplated and the relationship established by the Loan Documents, or any act,
omission or event occurring in connection therewith, unless it is determined in
a final non-appealable judgment by a court of competent jurisdiction that such
losses resulted from the gross negligence or willful misconduct of the party
from which recovery is sought. Neither the

                                       37
<PAGE>   43

Agent, the Arranger nor any Lender shall have any liability with respect to, and
the Borrower hereby waives, releases and agrees not to sue for, any special,
indirect or consequential damages suffered by the Borrower in connection with,
arising out of, or in any way related to the Loan Documents or the transactions
contemplated thereby.

          1.94  Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to such Lender or to a Transferee, (iii) to regulatory
officials, (iv) to any Person as requested pursuant to or as required by law,
regulation, or legal process, (v) to any Person in connection with any legal
proceeding to which such Lender is a party, (vi) to such Lender's direct or
indirect contractual counterparties in swap agreements or to legal counsel,
accountants and other professional advisors to such counterparties, and (vii)
permitted by Section 12.4.

          1.95  Nonreliance. Each Lender hereby represents that it is not
relying on or looking to any margin stock (as defined in Regulation U of the
Board of Governors of the Federal Reserve System) for the repayment of the Loans
provided for herein.

                                    ARTICLE X

                                    THE AGENT

          1.96  Appointment; Nature of Relationship. Bank One, NA is hereby
appointed by each of the Lenders as its contractual representative (herein
referred to as the "Agent") hereunder and under each other Loan Document, and
each of the Lenders irrevocably authorizes the Agent to act as the contractual
representative of such Lender with the rights and duties expressly set forth
herein and in the other Loan Documents. The Agent agrees to act as such
contractual representative upon the express conditions contained in this Article
X. Notwithstanding the use of the defined term "Agent," it is expressly
understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that the Agent is merely acting as the contractual representative
of the Lenders with only those duties as are expressly set forth in this
Agreement and the other Loan Documents. In its capacity as the Lenders'
contractual representative, the Agent (i) does not hereby assume any fiduciary
duties to any of the Lenders, (ii) is a "representative" of the Lenders within
the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting
as an independent contractor, the rights and duties of which are limited to
those expressly set forth in this Agreement and the other Loan Documents. Each
of the Lenders hereby agrees to assert no claim against the Agent on any agency
theory or any other theory of liability for breach of fiduciary duty, all of
which claims each Lender hereby waives.

                                       38
<PAGE>   44

          1.97  Powers. The Agent shall have and may exercise such powers under
the Loan Documents as are specifically delegated to the Agent by the terms of
each thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.

          1.98  General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

          1.99  No Responsibility for Loans, Recitals, etc. Neither the Agent
nor any of its directors, officers, agents or employees shall be responsible for
or have any duty to ascertain, inquire into, or verify (a) any statement,
warranty or representation made in connection with any Loan Document or any
borrowing hereunder; (b) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any Lien in any
collateral security; or (g) the financial condition of the Borrower or any
guarantor of any of the Obligations or of any of the Borrower's or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Lenders information that is not required to be furnished by the Borrower to
the Agent at such time, but is voluntarily furnished by the Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

          1.100 Action on Instructions of Lenders. The Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under
any other Loan Document in accordance with written instructions signed by the
Required Lenders, and such instructions and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first be indemnified to its satisfaction by the Lenders pro rata against any and
all liability, cost and expense that it may incur by reason of taking or
continuing to take any such action.

                                       39
<PAGE>   45

          1.101 Employment of Agents and Counsel. The Agent may execute any of
its duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

          1.102 Reliance on Documents; Counsel. The Agent shall be entitled to
rely upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

          1.103 Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders, in connection with the preparation,
execution, delivery, administration and enforcement of the Loan Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of the Loan
Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such
amounts incurred by or asserted against the Agent in connection with any dispute
between the Agent and any Lender or between two or more of the Lenders), or the
enforcement of any of the terms of the Loan Documents or of any such other
documents, provided that (i) no Lender shall be liable for any of the foregoing
to the extent any of the foregoing is found in a final non-appealable judgment
by a court of competent jurisdiction to have resulted from the gross negligence
or willful misconduct of the Agent and (ii) any indemnification required
pursuant to Section 3.5(iv) shall, notwithstanding the provisions of this
Section 10.8, be paid by the relevant Lender in accordance with the provisions
thereof. The obligations of the Lenders under this Section 10.8 shall survive
payment of the Obligations and termination of this Agreement.

          1.104 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Unmatured Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower referring to this Agreement describing such Default

                                       40
<PAGE>   46

or Unmatured Default and stating that such notice is a "notice of default". In
the event that the Agent receives such a notice, the Agent shall give prompt
notice thereof to the Lenders.

          1.105 Rights as a Lender. In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person.

          1.106 Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other Loan
Documents. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Arranger 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 and the other Loan Documents.

          1.107 Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders, such removal
to be effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on
behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent
shall have been so appointed by the Required Lenders within thirty days after
the resigning Agent's giving notice of its intention to resign, then the
resigning Agent may appoint, on behalf of the Borrower and the Lenders, a
successor Agent. Notwithstanding the previous sentence, the Agent may at any
time without the consent of the Borrower or any Lender, appoint any of its
Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been appointed,
the Lenders may perform all the duties of the Agent hereunder and the Borrower
shall make all payments in respect of the Obligations to the applicable Lender
and for all other purposes shall deal directly with the Lenders. No successor
Agent shall be deemed to be appointed hereunder until such successor Agent has
accepted the appointment. Any such successor Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor

                                       41
<PAGE>   47

Agent, such successor Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the resigning or removed Agent.
Upon the effectiveness of the resignation or removal of the Agent, the resigning
or removed Agent shall be discharged from its duties and obligations hereunder
and under the Loan Documents. After the effectiveness of the resignation or
removal of an Agent, the provisions of this Article X shall continue in effect
for the benefit of such Agent in respect of any actions taken or omitted to be
taken by it while it was acting as the Agent hereunder and under the other Loan
Documents. In the event that there is a successor to the Agent by merger, or the
Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 10.12, then the term "Corporate Base Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new Agent.

          1.108 Delegation to Affiliates. The Borrower and the Lenders agree
that the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Agreement shall be
entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Articles IX and X.

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

          1.109 Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender or
any Affiliate of any Lender to or for the credit or account of the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part hereof, shall then be due.

          1.110 Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to their Loans. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

                                       42
<PAGE>   48

                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

          1.111 Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (ii) any assignment by any Lender must be made in compliance
with Section 12.3. Notwithstanding clause (ii) of this Section, any Lender may
at any time, without the consent of the Borrower or the Agent, assign all or any
portion of its rights under this Agreement and any Note to a Federal Reserve
Bank; provided, however, that no such assignment to a Federal Reserve Bank shall
release the transferor Lender from its obligations hereunder. The Agent may
treat the Person which made any Loan or which holds any Note as the owner
thereof for all purposes hereof unless and until such Person complies with
Section 12.3 in the case of an assignment thereof or, in the case of any other
transfer, a written notice of the transfer is filed with the Agent. Any assignee
or transferee of the rights to any Loan or any Note agrees by acceptance of such
transfer or assignment to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the owner of the
rights to any Loan (whether or not a Note has been issued in evidence thereof),
shall be conclusive and binding on any subsequent holder, transferee or assignee
of the rights to such Loan.

          1.112 Participations.

                12.2.1. Permitted Participants; Effect. Any Lender may, in the
          ordinary course of its business and in accordance with applicable law,
          at any time sell to one or more banks or other entities
          ("Participants") participating interests in any Loan owing to such
          Lender, any Note held by such Lender, any Commitment of such Lender or
          any other interest of such Lender under the Loan Documents. In the
          event of any such sale by a Lender of participating interests to a
          Participant, such Lender's obligations under the Loan Documents shall
          remain unchanged, such Lender shall remain solely responsible to the
          other parties hereto for the performance of such obligations, such
          Lender shall remain the owner of its Loans and the holder of any Note
          issued to it in evidence thereof for all purposes under the Loan
          Documents, all amounts payable by the Borrower under this Agreement
          shall be determined as if such Lender had not sold such participating
          interests, and the Borrower and the Agent shall continue to deal
          solely and directly with such Lender in connection with such Lender's
          rights and obligations under the Loan Documents.

                12.2.2. Voting Rights. Each Lender shall retain the sole right
          to approve, without the consent of any Participant, any amendment,
          modification or waiver of any provision of

                                       43
<PAGE>   49

          the Loan Documents other than any amendment, modification or waiver
          with respect to any Loan or Commitment in which such Participant has
          an interest which forgives principal, interest or fees or reduces the
          interest rate or fees payable with respect to any such Loan or
          Commitment, extends the Facility Termination Date or postpones any
          date fixed for any regularly-scheduled payment of principal of, or
          interest or fees on, any such Loan or Commitment.

                12.2.3. Benefit of Setoff. The Borrower agrees that each
          Participant shall be deemed to have the right of setoff provided in
          Section 11.1 in respect of its participating interest in amounts owing
          under the Loan Documents to the same extent as if the amount of its
          participating interest were owing directly to it as a Lender under the
          Loan Documents, provided that each Lender shall retain the right of
          setoff provided in Section 11.1 with respect to the amount of
          participating interests sold to each Participant. The Lenders agree to
          share with each Participant, and each Participant, by exercising the
          right of setoff provided in Section 11.1, agrees to share with each
          Lender, any amount received pursuant to the exercise of its right of
          setoff, such amounts to be shared in accordance with Section 11.2 as
          if each Participant were a Lender.

          1.113 Assignments.

                12.3.1. Permitted Assignments. Any Lender may, in the ordinary
          course of its business and in accordance with applicable law, at any
          time assign to one or more banks or other entities organized under the
          laws of the United States or a state thereof ("Purchasers") all or any
          part of its rights and obligations under the Loan Documents. Such
          assignment shall be substantially in the form of Exhibit C or in such
          other form as may be agreed to by the parties thereto. The consent of
          the Borrower and the Agent shall be required prior to an assignment
          becoming effective with respect to a Purchaser which is not a Lender
          or an Affiliate thereof; provided, however, that if a Default has
          occurred and is continuing, the consent of the Borrower shall not be
          required. Such consent shall not be unreasonably withheld or delayed.
          Each such assignment with respect to a Purchaser which is not a Lender
          or an Affiliate thereof shall (unless each of the Borrower and the
          Agent otherwise consents) be in an amount not less than the lesser of
          (i) $3,500,000 or (ii) the remaining amount of the assigning Lender's
          Commitment (calculated as at the date of such assignment) or
          outstanding Loans (if the applicable Commitment has been terminated).

                12.3.2. Effect; Effective Date. Upon (i) delivery to the Agent
          of an assignment, together with any consents required by Section
          12.3.1, and (ii) payment of a $3,000 fee to the Agent by the selling
          Lender or the Purchaser for processing such assignment (unless such
          fee is waived by the Agent), such assignment shall become effective on
          the effective

                                       44
<PAGE>   50

          date specified in such assignment. The assignment shall contain a
          representation by the Purchaser to the effect that none of the
          consideration used to make the purchase of the Commitment and Loans
          under the applicable assignment agreement constitutes "plan assets" as
          defined under ERISA and that the rights and interests of the Purchaser
          in and under the Loan Documents will not be "plan assets" under ERISA.
          On and after the effective date of such assignment, such Purchaser
          shall for all purposes be a Lender party to this Agreement and any
          other Loan Document executed by or on behalf of the Lenders and shall
          have all the rights and obligations of a Lender under the Loan
          Documents, to the same extent as if it were an original party hereto,
          and no further consent or action by the Borrower, the Lenders or the
          Agent shall be required to release the transferor Lender with respect
          to the percentage of the Aggregate Commitment and Loans assigned to
          such Purchaser. Upon the consummation of any assignment to a Purchaser
          pursuant to this Section 12.3.2, the transferor Lender, the Agent and
          the Borrower shall, if the transferor Lender or the Purchaser desires
          that its Loans be evidenced by Notes, make appropriate arrangements so
          that new Notes or, as appropriate, replacement Notes are issued to
          such transferor Lender and new Notes or, as appropriate, replacement
          Notes, are issued to such Purchaser, in each case in principal amounts
          reflecting their respective Commitments, as adjusted pursuant to such
          assignment.

          1.114 Dissemination of Information. The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person acquiring
an interest in the Loan Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries, including
without limitation any information contained in any Reports; provided that each
Transferee and prospective Transferee agrees to be bound by Section 9.11 of this
Agreement.

          1.115 Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(iv).

respect to borrowing notices, all notices, requests and other communications to

this Section 13.1. Each such notice, request or other communication shall be

          1.117 Change of Address. The Borrower, the Agent and any Lender may
each change the address for service of notice upon it by a notice in writing to
the other parties hereto.

                                   ARTICLE XIV

                                  COUNTERPARTS

          This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrower, the
Agent and the Lenders and each party has notified the Agent by facsimile
transmission or telephone that it has taken such action.

                                   ARTICLE XV

          CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

          1.118 CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH

SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE
STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL
BANKS.

          1.119 CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE
COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT
ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED
IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER
HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A
COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT
THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER
IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE

                                       46

BORROWER AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE AGENT OR ANY

          1.120 WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH LENDER
HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY
WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.

                                 FORM OF OPINION

                                                                      , 2000

The Agent and the Lenders who are parties to the
Credit Agreement described below.

Gentlemen/Ladies:

     We are counsel for Integra Bank Corporation (the "Borrower"), and have
represented the Borrower in connection with its execution and delivery of a
Credit Agreement dated as of ____________, 2000 (the "Agreement") among the
Borrower, the Lenders named therein, and Bank One, NA, as Agent, and providing
for Advances in an aggregate principal amount not exceeding $50,000,000 at any
one time outstanding. All capitalized terms used in this opinion and not
otherwise defined herein shall have the meanings attributed to them in the
Agreement.

     We have examined the Borrower's **[describe constitutive documents of
Borrower and appropriate evidence of authority to enter into the transaction]**,
the Loan Documents and such other matters of fact and law which we deem
necessary in order to render this opinion. Based upon the foregoing, it is our
opinion that:

     l. Each of the Borrower and each of its Major Bank Subsidiaries is a
corporation or national banking association duly and properly incorporated or
organized, as the case may be, validly existing and (to the extent such concept
applies to such entity) in good standing under the laws of its jurisdiction of
incorporation or organization and has all requisite authority to conduct its
business in each jurisdiction in which its business is conducted.

     2. The execution and delivery by the Borrower of the Loan Documents and the
performance by the Borrower of its obligations thereunder have been duly
authorized by proper corporate proceedings on the part of the Borrower and will
not:

        (a) require any consent of the Borrower's shareholders (other than any
     such consent as has already been given and remains in full force and
     effect);

        (b) violate (i) any law, rule, regulation, order, writ, judgment,
     injunction, decree or award binding on the Borrower or any of its Major
     Bank Subsidiaries or (ii) the

                                   Exhibit A-1

<PAGE>   60

     Borrower's or any Major Bank Subsidiary's articles or certificate of
     incorporation or association, partnership agreement, certificate of
     partnership, articles or certificate of organization, by-laws, or operating
     or other management agreement, as the case may be, or (iii) the provisions
     of any indenture, instrument or agreement to which the Borrower or any of
     its Subsidiaries is a party or is subject, or by which it, or its Property,
     is bound, or conflict with or constitute a default thereunder; or

        (c) result in, or require, the creation or imposition of any Lien in,
     of or on the Property of the Borrower or a Major Bank Subsidiary pursuant
     to the terms of any indenture, instrument or agreement binding upon the
     Borrower or any of its Major Bank Subsidiaries.

     3. The Loan Documents have been duly executed and delivered by the Borrower
and constitute legal, valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their terms except to the extent the
enforcement thereof may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally and subject also to the
availability of equitable remedies if equitable remedies are sought.

     4. There is no litigation, arbitration, governmental investigation,
proceeding or inquiry pending or, to the best of our knowledge after due
inquiry, threatened against the Borrower or any of its Major Bank Subsidiaries
which, if adversely determined, could reasonably be expected to have a Material
Adverse Effect.

     5. No order, consent, adjudication, approval, license, authorization, or
validation of, or filing, recording or registration with, or exemption by, or
other action in respect of any governmental or public body or authority, or any
subdivision thereof, which has not been obtained by the Borrower or any of its
Major Bank Subsidiaries, is required to be obtained by the Borrower or any of
its Major Bank Subsidiaries in connection with the execution and delivery of the
Loan Documents, the borrowings under the Agreement, the payment and performance
by the Borrower of the Obligations, or the legality, validity, binding effect or
enforceability of any of the Loan Documents.

                          INSURANCE AUTO AUCTIONS, INC.
                             1991 STOCK OPTION PLAN

                             AS RESTATED AND AMENDED
                             THROUGH APRIL 24, 2000

I.   PURPOSE.

     This Insurance Auto Auctions, Inc. 1991 Stock Option Plan ("Plan") is
intended to enable Insurance Auto Auctions, Inc. ("Corporation") to attract and
retain the following individuals and to encourage such individuals to acquire a
proprietary interest in the Corporation: (a) employees (including officers and
directors) of the Corporation and its subsidiaries primarily responsible for the
management, growth and financial success of the Corporation and its
subsidiaries, (b) non-employee members of the Corporation's Board of Directors
and (c) consultants and independent contractors who perform valuable services
for the Corporation or its subsidiaries.

II.  ADMINISTRATION.

     The Plan will be administered by a committee or committees appointed by the
Corporation's Board of Directors ("Board"), and each such committee shall
consist of one or more members of the Board. The Board may delegate the
responsibility for administration of the Plan with respect to designated classes
of optionees to different committees, subject to such limitations as the Board
deems appropriate. With respect to any matter, the term "Committee," when used
in this Plan, will refer to the committee that has been delegated authority with
respect to such matter. Members of a committee will serve for such term as the
Board may determine and will be subject to removal by the Board at any time.

     (a)  16(b). The composition of any committee responsible for administration
of the Plan with respect to optionees who are subject to the short-swing profit
restrictions of Section 16(b) of the Securities Exchange Act of 1934, as amended
("1934 Act") with respect to their trading in securities of the Corporation will
be comprised of two or more non-employee Board members who have not received, at
any time during the one-year period preceding the date of their appointment to
such committee or (if shorter) during the period between the initial
registration of the Corporation's equity securities under Section 12 of the 1934
Act and such appointment, any stock options, stock appreciation rights or stock
issuances under this Plan or under any other stock option, stock appreciation,
stock bonus, stock purchase or other stock plan of the Corporation or its
subsidiaries, except for automatic option grants made pursuant to Section VI of
this Plan.

     (b)  AUTHORITY. Any committee appointed by the Board will have full
authority to administer the Plan within the scope of its delegated
responsibilities, including authority to interpret and construe any relevant
provision of the Plan, to adopt such rules and regulations as it may deem
necessary, and to determine the terms of the grants made from time to time under
the Plan (which need not be identical). Decisions of a committee made within the
discretion

<PAGE>   2

delegated to it by the Board will be final and binding on all persons who have
an interest in the Plan.

III.      ELIGIBILITY FOR AWARDS.

          (a)  DISCRETIONARY AWARDS. The Committee may, in its discretion,
select individuals from among the following categories to receive options under
the Plan:

               (1)  KEY EMPLOYEES. The Committee may select key employees of the
Corporation or its subsidiaries (including officers, whether or not they are
also members of the Board).

               (2)  CONSULTANTS AND INDEPENDENT CONTRACTORS. The Committee may
select consultants and independent contractors whose services tend to contribute
materially to the success of the Corporation or its subsidiaries or whose
services may reasonably be anticipated to so contribute.

               Prior to November 20, 1991 ("IPO Date"), discretionary grants
could be made to members of the Board who were not employees of the Corporation
or its subsidiaries.

     (b)  AUTOMATIC GRANTS. On and after the IPO Date, members of the Board who
are not employees of the Corporation or its subsidiaries will receive options in
accordance with, and only in accordance with, the Automatic Option Grant
provisions of Section VI.

IV.       STOCK SUBJECT TO THE PLAN.

          (a)  CLASS. The stock subject to options granted under the Plan is the
Corporation's authorized but unissued or reacquired shares of Common Stock
("Common Stock"). In connection with the issuance of shares under the Plan, the
Corporation may repurchase shares in the open market or otherwise.

          (b)  AGGREGATE AMOUNT.

               (1)  SHARES. Subject to adjustment under Section IV(c), the
maximum number of shares of Common Stock issuable under the Plan is 2,350,000
shares(1). However, not more than 2,266,319 shares may be issued from and after
March 31, 1996, subject to periodic adjustment under Section IV(c).

               (2)  PARTICIPANT LIMITATION. No individual participating in the
Plan may be granted stock options and separately exercisable stock appreciation
rights for more than 500,000 shares of Common Stock over the remaining term of
the Plan, subject to periodic adjustment under Section IV(c). For purposes of
such limitation, no stock options or stock appreciation rights granted prior to
January 1, 1994 shall be taken into account.

--------------------
(1)  Includes the 1,000,000-share increases authorized by the Board on April 24,
     2000, subject to shareholder approval at the 2000 Annual Meeting.

                                       2
<PAGE>   3

               (3) REUSE OF SHARES. If any outstanding option under this Plan
expires or terminates for any reason (including cancellation pursuant to Section
IX of the Plan) before being exercised for the full number of shares to which it
applies, the shares allocable to the unexercised portion of such option will not
be charged against the limitation of Section IV(b)(1) and will become available
for subsequent grants under the Plan. Shares subject to any option (or portion
thereof) surrendered or cancelled in accordance with the "Surrender or
Cancellation of Options for Cash or Stock" provisions of this Plan and all stock
issuances under the Plan, whether or not the shares are subsequently repurchased
by the Corporation pursuant to its repurchase rights under the Plan, shall
reduce on a share-for-share basis the number of shares of Common Stock available
for subsequent issuance under this Plan. Should the exercise price of an
outstanding option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an outstanding option under the Plan, the number of shares of
Common Stock issuable under the Plan shall be reduced by the gross number of
shares for which the option is exercised, and not by the net number of shares of
Common Stock actually issued to the option holder.

          (c)  ADJUSTMENTS. In the event any change is made to the Common Stock
subject to the Plan or subject to any outstanding option granted under the Plan
(whether by reason of merger, consolidation, reorganization, recapitalization,
stock dividend, stock split, combination of shares, exchange of shares, or other
change in corporate or capital structure of the Corporation effected without the
Corporation's receipt of consideration) then, unless such change results in the
termination of all outstanding options, the Committee shall make appropriate
adjustments to (i) the maximum number and/or class of securities available for
issuance under the Plan, (ii) the maximum number and/or class of securities for
which any one individual may be granted stock options and separately-exercisable
stock appreciation rights under the Plan after December 31, 1993, (iii) the
number and/or class of securities and the price per share in effect under each
outstanding option under the Plan (including the automatic option grants) and
(iv) the number and/or class of securities per non-employee Board member for
which automatic option grants are subsequently to be made under the Automatic
Option Grant provisions of the Plan. The adjustments made by the Committee will
be final, binding and conclusive and will be designed to prevent the dilution or
enlargement of rights and benefits under the Plan.

V.        TERMS OF OPTIONS.

          Stock options granted under the Plan may, in the Committee's
discretion, be either incentive stock options ("Incentive Options") qualifying
under Section 422 of the Internal Revenue Code of 1986, as amended ("Internal
Revenue Code"), or nonstatutory options. Individuals who are not employees of
the Corporation or its subsidiaries may only be granted nonstatutory options.
Options will be evidenced by instruments in such form as the Committee may from
time to time approve. These instruments will conform to the following terms and,
in the discretion of the Committee, may contain such other terms and
restrictions as are not inconsistent with the following:

                                       3
<PAGE>   4

          (a)  OPTION PRICE. The option price per share will be fixed by the
Committee; provided, however, that in no event will the option price per share
of an Incentive Option be less than one hundred percent (100%), or with respect
to nonstatutory options, eighty-five percent (85%), of the Fair Market Value of
a share of Common Stock on the date of the option grant.

          (b)  NUMBER OF SHARES, TERM AND EXERCISE.

               (1) TERM AND NUMBER. Each option granted under the Plan will be
exercisable on such date or dates, during such period, and for such number of
shares of Common Stock as the Committee determines and sets forth in the
instrument evidencing the option. No option granted under the Plan will be
exercisable after the expiration of ten (10) years from the date the option was
granted.

               (2) EXERCISE. After any option granted under the Plan becomes
exercisable, it may be exercised by notice to the Corporation at any time prior
to the termination of such option. Except as authorized by the Committee in
accordance with Section VII, the option price for the number of shares for which
the option is exercised will become immediately due and payable upon exercise.

               (3) PAYMENT. The option price will be payable in full in cash
(including cash equivalents); provided, however, that the Committee may, either
at the time the option is granted or at the time the option is exercised and
subject to such limitations as the Committee may determine, authorize payment of
all or a portion of the option price in one or a combination of the following
alternative forms:

                    (i)    a promissory note authorized pursuant to Section VII;
                           or

                    (ii)   delivery of a properly-executed exercise notice,
                           together with irrevocable instructions to a
                           Corporation-designated broker to promptly deliver to
                           the Corporation the amount of sale or loan proceeds
                           to pay the option price for the purchased shares; or

                    (iii)  full payment in shares of Common Stock valued at Fair
                           Market Value on the exercise date and held for the
                           requisite period to avoid a charge to the
                           Corporation's earnings.

          (c)  TERMINATION OF EMPLOYMENT. The Committee will have complete
discretion to determine and set forth in each option agreement whether the
option will continue to be exercisable, and the terms of such exercise, on and
after the date that an optionee ceases to be employed by, or to provide services
to, the Corporation or its subsidiaries. Included within such discretion shall
be the authority of the Committee, exercisable either at the time the option is
granted or at any time while the option remains outstanding, to permit one or
more options held by the optionee to be exercised, during the limited period of
exercisability following the optionee's cessation of employment or service, not
only with respect to the number of shares in which the optionee is at that time
vested but also with respect to one or more subsequent installments of
purchasable shares in which the optionee would otherwise have vested had the

                                       4
<PAGE>   5

optionee continued in employment or service. The Committee will also have
complete discretion, exercisable at any time while the option remains
outstanding, to extend the period for which that option is to remain exercisable
following the optionee's cessation of employment or service, but in no event may
such period be extended beyond the specified expiration date of the option term.

          (d)  INCENTIVE  OPTIONS.  Options granted under the Plan that are
intended to be Incentive Options will be subject to the following additional
terms:

               (1)  DOLLAR LIMITATION. To the extent that the aggregate Fair
Market Value (determined as of the respective date or dates of grant) of shares
with respect to which options that would otherwise be Incentive Options become
exercisable for the first time by any individual during any calendar year under
the Plan (or any other plan of the Corporation, a parent or subsidiary
corporation or predecessor thereof) exceeds the sum of $100,000 (or such greater
amount as may be permitted under the Internal Revenue Code), whether by reason
of acceleration or otherwise, such options will not be treated as Incentive
Options. In making such determination, options will be taken into account in the
order in which they were granted. To the extent the $100,000 limitation on the
initial exercisability of Incentive Options would otherwise be exceeded in any
calendar year, the option or options shall nevertheless become exercisable in
that calendar year for the excess number of shares as nonstatutory options.

               (2)  10% SHAREHOLDER. If any employee to whom an Incentive Option
is to be granted pursuant to the provisions of the Plan is, on the date of
grant, the owner of stock (determined with application of the ownership
attribution rules of Section 424(d) of the Internal Revenue Code) possessing
more than ten percent (10%) of the total combined voting power of all classes of
stock of his or her employer corporation or of its parent or subsidiary
corporation ("10% Shareholder"), then the following special provisions will
apply to the option granted to such individual:

                    (i)    The option price per share of the stock subject to
                           such Incentive Option will not be less than one
                           hundred ten percent (110%) of the Fair Market Value
                           of the option shares on the date of grant; and

                    (ii)   The option will not have a term in excess of five (5)
                           years from the date of grant.

               (3)  PARENT AND SUBSIDIARY. For purposes of this Section V(d)
"parent corporation" and "subsidiary corporation" will have the meaning
attributed to those terms as they are used in Section 424 of the Internal
Revenue Code.

          (e)  WITHHOLDING.

               (1)  OBLIGATION. The Corporation's obligation to deliver stock
certificates upon the exercise of an option will be subject to the option
holder's satisfaction of all applicable federal, state and local income and
employment tax withholding requirements.

                                       5
<PAGE>   6

               (2)  PAYMENT. The Committee may, in its discretion and upon such
terms and conditions as it may deem appropriate (including the applicable
safe-harbor provisions of SEC Rule 16b-3 or any successor rule or regulation)
provide any or all holders of outstanding option grants under the Plan with the
election to have the Corporation withhold, from the shares of Common Stock
otherwise issuable upon the exercise of such options, a portion of such shares
with an aggregate Fair Market Value equal to the designated percentage (up to
100% as specified by the option holder) of the federal and state income and
employment taxes ("Taxes") incurred in connection with the acquisition of such
shares. In lieu of such direct withholding, one or more optionees may also be
granted the right to deliver previously-acquired shares of Common Stock to the
Corporation in satisfaction of such Taxes. The withheld or delivered shares
shall be valued at the Fair Market Value on the applicable determination date
for such Taxes or such other date required by the applicable safe-harbor
provisions of SEC Rule 16b-3.

          (f)  REPURCHASE RIGHTS. The Committee may, in its discretion,
establish as a term of one or more options that the Corporation (or its assigns)
will have the right, exercisable upon the optionee's termination of employment
with, or cessation of service to, the Corporation and its subsidiaries, to
repurchase at the original option price any or all of the shares of Common Stock
acquired by such optionee upon exercise of the option. Any such repurchase right
will be exercisable by the Corporation (or its assigns) upon such terms
(including provisions for the expiration of such right in one or more
installments) as the Committee may specify in the instrument evidencing such
right.

          (g)  SHAREHOLDER RIGHTS. An option holder shall have no shareholder
rights with respect to any shares covered by the option until such individual
shall have exercised the option, paid the option price and satisfied all other
conditions precedent to the issuance of the stock certificates for the purchased
shares.

VI.       AUTOMATIC OPTION GRANTS TO DIRECTORS.

          (a)  GRANTS. Each non-employee member of the Board shall automatically
be granted nonstatutory options ("Automatic Option Grants") to purchase the
number of shares of Common Stock indicated below (subject to adjustment under
Section IV(c) of this Plan) on the dates and pursuant to the terms and
conditions set forth below. Such terms and conditions have been revised
effective February 22, 1994, but such revisions shall not affect any outstanding
options granted under this Section VI prior to such date. However, all option
grants made pursuant to the revised provisions of this Section VI as effective
February 22, 1994 shall not become exercisable in whole or in part unless those
revisions are approved by the Corporation's shareholders at the 1994 Annual
Meeting. If such shareholder approval is not obtained, then the provisions of
this Section VI as last approved by the shareholders shall automatically be
reinstated and continue to govern all subsequent Automatic Option Grants made
under the Plan.

               (1)  INITIAL IPO GRANTS. Each individual who was a non-employee
Board member on the IPO Date received at that time an Automatic Option Grant to
purchase 5,000 shares of Common Stock.

                                       6
<PAGE>   7

               (2)  OCTOBER 28, 1992 GRANTS. Each individual who was serving as
a non-employee Board member on October 28, 1992 was on that date granted an
Automatic Option Grant to purchase an additional 1,000 shares of Common Stock.

               (3)  NEW DIRECTORS PRIOR TO FEBRUARY 22, 1994. Each person who
was first elected or appointed as a non-employee member of the Board after
October 28, 1992 but prior to February 22, 1994 received, on the effective date
of such initial election or appointment, an Automatic Option Grant to purchase
5,000 shares of Common Stock.

               (4)  NEW DIRECTORS AFTER FEBRUARY 21, 1994. Each person who is
first elected or appointed as a non-employee member of the Board on or after
February 22, 1994 shall receive, on the effective date of such initial election
or appointment, an Automatic Option Grant to purchase 10,000 shares of Common
Stock.

               (5)  SPECIAL GRANT. Each individual who is re-elected as a
non-employee Board member at the 1994 Annual Shareholders Meeting shall receive
at that time an Automatic Option Grant to purchase an additional 5,000 shares of
Common Stock, provided the February 22, 1994 amendment to the Plan is approved
by the shareholders at the 1994 Annual Meeting.

               (6)  CONTINUING DIRECTORS. On the last business day of the second
quarter (the "Automatic Grant Date") of each fiscal year of the Corporation
beginning after October 28, 1992, each individual who is at that time serving as
a non-employee member of the Board will receive an Automatic Option Grant to
purchase an additional 2,000 shares(2) of Common Stock. However, an individual
who is first elected or appointed as a non-employee Board member after October
28, 1992 shall not receive his or her first Automatic Option Grant for 2,000
shares under this subparagraph (6) until the last business day of the second
quarter of the fiscal year immediately following the fiscal year of his or her
initial election or appointment to the Board.

          (b)  TERMS. The terms applicable to each Automatic Option Grant shall
be as follows:

               (1)  PRICE. The option price per share will be equal to one
hundred percent (100%) of the Fair Market Value of one share of Common Stock on
the date of grant.

               (2)  TERM. Each Automatic Option Grant shall have a maximum term
of ten (10) years, measured from the date of grant.

               (3)  VESTING. Subject to paragraphs (4) and (5) below, each
Automatic Option Grant shall become exercisable as to twenty-five percent (25%)
of the option shares on the last business day of the fiscal quarter immediately
following the date of grant and as to an additional twenty-five percent (25%) of
the option shares on the last business day of each of the next three (3) fiscal
quarters thereafter, provided the optionee continues to serve as a Board member.

--------------------
(2)  Prior to October 28, 1992 amendment to Section VI, each periodic option
     grant was for 1,000 shares of Common Stock.

                                       7
<PAGE>   8
               (4)  CESSATION. The option will terminate three (3) months
(twelve (12) months in the case of cessation by reason of disability or death)
after the optionee ceases to serve as a Board member unless the option would
terminate sooner under paragraph (2) above. In the case of death, the option may
be exercised within the applicable period by the estate or heirs of the
optionee.

               (5)  ACCELERATION. The options will be subject to the
acceleration provisions contained in Section X(a) of this Plan.

               (6)  PAYMENT. Upon exercise of the option, the option price for
the purchased shares will become payable immediately in cash, in shares of
Common Stock of the Corporation that the optionee has held for at least six (6)
months, or by delivery of a properly-executed exercise notice, together with
irrevocable instructions to a Corporation-designated broker to promptly deliver
to the Corporation the amount of sale or loan proceeds to pay the option price
for the purchased shares.

VII.      LOANS AND INSTALLMENT PAYMENTS.

          In order to assist an optionee (including an employee who is an
officer or member of the Board) in the acquisition of shares pursuant to an
option granted under the Plan (other than pursuant to the Automatic Option Grant
provisions of this Plan), the Committee may authorize, at either the time of the
grant of an option or the time of the acquisition of shares under the option,
(i) the extension of a loan to the optionee by the Corporation, (ii) the payment
by the optionee of the option price for the purchased option shares in
installments, or (iii) the guarantee by the Corporation of a loan obtained by
the optionee from a third party. The terms of any loans, guarantees or
installment payments, including the interest rate and terms of repayment, will
be subject to the discretion of the Committee. Loans, installment payments and
guarantees may be granted without security, but the maximum credit available to
the optionee shall be limited to the option price of the purchased option shares
(less the par value of such shares) plus the maximum federal and state income
and employment tax liability that may be incurred in connection with the
acquisition.

VIII.     ASSIGNABILITY.

          No option or stock appreciation right granted under the Plan is
assignable or transferable by the optionee other than by will or by the laws of
descent and distribution, and during the lifetime of the optionee the granted
option or stock appreciation right may be exercised only by the optionee.

IX.       CANCELLATION AND NEW GRANT OF OPTIONS.

          The Committee will have the authority to effect, at any time and from
time to time, with the consent of the affected option holders, the cancellation
of any or all outstanding options under the Plan (other than options granted
under the Automatic Option Grant provisions of this Plan) and to grant in
substitution therefor new options under the Plan covering the same or different
numbers of shares, but with an option price per share not less than eighty-five
percent

                                       8
<PAGE>   9

(85%) of the Fair Market Value of the option shares on the new grant date or, in
the case of an Incentive Option, one hundred percent (100%) of such Fair Market
Value on the new grant date (or, in the case of an Incentive Option granted to a
10% Shareholder, one hundred ten percent (110%) of such Fair Market Value). The
Committee shall not effect a cancellation and substitution grant as described in
the foregoing sentence without the prior approval of the shareholders of the
Corporation.

X.        ACCELERATION AND TERMINATION OF OPTIONS.

          (a)  ACCELERATION. In the event of one or more of the following
shareholder-approved transactions ("Corporate Transactions"):

               (1)  a merger or acquisition in which the Corporation is not the
surviving entity, except for a transaction the principal purpose of which is to
change the State of the Corporation's incorporation,

               (2)  the sale, transfer or other disposition of all or
substantially all of the assets or outstanding capital stock of the Corporation,
or

               (3)  any reverse merger in which the Corporation is the surviving
entity but in which all of the Corporation's outstanding voting stock is
transferred to the acquiring entity or its wholly-owned subsidiary,

then each option outstanding under the Plan will become exercisable, immediately
prior to the consummation of such Corporate Transaction, with respect to the
full number of shares of Common Stock at the time subject to that option and may
be exercised for any or all of those shares as fully-vested shares. Immediately
following the consummation of the Corporate Transaction, all outstanding options
will terminate and cease to be exercisable, except to the extent assumed by the
successor corporation or parent thereof.

          (b)  ADJUSTMENTS TO SHARES. Each outstanding option which is assumed
in connection with the Corporate Transaction or is otherwise to continue in
effect will be appropriately adjusted, immediately after such Corporate
Transaction, to apply and pertain to the number and class of securities which
would have been issuable, in consummation of such Corporate Transaction, to an
actual holder of the same number of shares of Common Stock subject to such
option immediately prior to such Corporate Transaction. Appropriate adjustments
will also be made to the option price payable per share, provided the aggregate
option price payable for such securities will remain the same. In addition, the
class and number of securities available for issuance under the Plan on both an
aggregate and per participant basis following the consummation of the Corporate
Transaction will be appropriately adjusted.

          (c)  CORPORATE STRUCTURE. The grant of options under this Plan will in
no way affect the right of the Corporation to adjust, reclassify, reorganize, or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

                                       9
<PAGE>   10

XI.       FAIR MARKET VALUE.

          For all valuation purposes under the Plan, the Fair Market Value of a
share of Common Stock (rounded upwards to the nearest whole cent) on any
relevant date will be determined in accordance with the following provisions:

          (a)  If the Common Stock is not at the time listed or admitted to
trading on any national securities exchange, but is traded on the Nasdaq
National Market, the Fair Market Value will be the closing selling price per
share of Common Stock on the trading day immediately preceding the date in
question, as such price is reported by the National Association of Securities
Dealers, Inc. through the Nasdaq National Market or any successor system.

          (b)  If the Common Stock is at the time listed or admitted to trading
on any national securities exchange, then the Fair Market Value will be the
closing selling price per share of Common Stock on the trading day immediately
preceding the date in question on the securities exchange that serves as the
primary market for the Common Stock, as such price is officially quoted on such
exchange.

          (c)  If the Common Stock is at the time neither listed nor admitted to
trading on any national securities exchange nor traded on the Nasdaq National
Market, then the Fair Market Value will be determined by the Committee after
taking into account such factors as the Committee deems appropriate.

XII.      SURRENDER OR CANCELLATION OF OPTIONS FOR CASH OR STOCK.

          (a)  If and only if the Committee, in its discretion, elects to
implement an option surrender program under the Plan, one or more option holders
may, upon such terms as the Committee may establish at the time of the option
grant or at any time thereafter, be granted the right to surrender all or part
of an unexercised option in exchange for a distribution equal in amount to the
excess of (i) the Fair Market Value (on the option surrender date) of the shares
for which the surrendered option or portion thereof is at the time exercisable
over (ii) the aggregate option price payable for such shares. The distribution
to which an option holder becomes entitled under this Section XII may be made in
shares of Common Stock, valued at Fair Market Value on the option surrender
date, in cash, or partly in shares and partly in cash, as the Committee, in its
sole discretion, deems appropriate. The option surrender provisions of this
Section XII will not apply to options granted pursuant to the Automatic Option
Grant provisions of this Plan.

          (b)  One or more officers of the Corporation subject to the
short-swing profit restrictions of the Federal securities laws may, in the Plan
Administrator's sole discretion, be granted limited stock appreciation rights in
tandem with their outstanding options under the Plan. Upon the occurrence of a
Hostile Take-Over effected at any time when the Corporation's outstanding Common
Stock is registered under Section 12(g) of the 1934 Act, each outstanding option
with such a limited stock appreciation right in effect for at least six (6)
months shall automatically be cancelled, and the officer shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to the cancelled option (whether or not the option is otherwise

                                       10
<PAGE>   11

at the time exercisable for such shares) over (ii) the aggregate option price
payable for such shares. The cash distribution payable upon such cancellation
shall be made within five (5) days following the consummation of the Hostile
Take-Over. Neither the approval of the Committee nor the consent of the Board
shall be required in connection with such option cancellation and cash
distribution.

          (c)  For purposes of subparagraph (b) above, the following definitions
shall be in effect:

               A Hostile Take-Over shall be deemed to occur in the event (i) any
          person or related group of persons (other than the Corporation or a
          person that directly or indirectly controls, is controlled by, or is
          under common control with, the Corporation) directly or indirectly
          acquires beneficial ownership (within the meaning of Rule 13d-3 of the
          1934 Act) of securities possessing more than fifty percent (50%) of
          the total combined voting power of the Corporation's outstanding
          securities pursuant to a tender or exchange offer made directly to the
          Corporation's shareholders which the Board does not recommend such
          shareholders to accept and (ii) more than fifty percent (50%) of the
          securities so acquired in such tender or exchange offer are accepted
          from holders other than the Corporation's officers and directors
          subject to Section 16(b) of the 1934 Act.

               The Take-Over Price per share shall be deemed to be equal to the
          greater of (a) the Fair Market Value per share of Common Stock on the
          date of the option cancellation or (b) the highest reported price per
          share of Common Stock paid in effecting such Hostile Take-Over.
          However, if the cancelled option is an Incentive Option, the Take-Over
          Price shall not exceed the clause (a) price per share.

          (d)  The shares of Common Stock subject to any option surrendered or
cancelled for an appreciation distribution pursuant to this Section XII shall
not be available for subsequent issuance under the Plan.

XIII.     EFFECTIVE DATE AND TERM.

          (a)  EFFECTIVE DATE. The Plan was originally adopted by the Board
effective on September 27, 1991 and approved by the shareholders on September
30, 1991. The Plan was restated on March 13, 1992 to increase the number of
shares issuable thereunder by 50,000 shares and to revise the Corporate
Transaction provisions, and such restated Plan was approved by the Corporation's
shareholders on May 27, 1992. The Board again amended the Plan, effective

Plan on March 9, 1993 to increase the number of shares of Common Stock issuable

the number of shares of Common Stock issuable under the Plan by an additional
300,000 shares, (ii) impose a 500,000-share limit on the maximum number of
shares of Common Stock for which any one participant may be granted stock

          (b)  RULE 16B-3 AMENDMENTS. On October 27, 1992, the Board amended the
March 13, 1992 restatement of the Plan in order to bring its provisions into
conformity with the revisions to Rule 16(b)-3 of the Securities and Exchange
Commission governing the treatment, for the purposes of the short-swing
liability provisions of the Federal securities laws, of certain transactions
effected under employee stock plans such as the Plan, and the Plan shall
accordingly become subject to such Rule 16b-3 revisions effective as of October
27, 1992.

          (c)  RESTATEMENTS. Each option issued and outstanding under the Plan
at the time of the adoption of the March 13, 1992 restatement was automatically
amended to incorporate the terms of the revised provisions of Section X of the
Plan applicable to Corporate Transactions. Except as so modified, nothing in the
March 13, 1992 restatement shall be deemed to affect or otherwise modify the
rights or obligations of the holders of such options with respect to their
acquisition of shares of Common Stock thereunder. The revisions to the Plan
effected by the October 27, 1992 restatement shall apply only to stock options
and stock appreciation rights granted under the Plan from and after the October
27, 1992 effective date. All stock options and stock appreciation rights which
were issued and outstanding under the Plan immediately prior to such effective
date shall continue to be governed by the terms and conditions of the Plan (and
the instrument evidencing each such option or stock appreciation right) as in
effect on the date each such option or stock appreciation right was previously
granted, and none of the October 27, 1992 revisions to the Plan shall affect or
otherwise modify the rights or obligations of the holders of such options or
stock appreciation rights with respect to the acquisition of shares of Common
Stock under those options or the exercise of their stock appreciation rights.
The revisions to the Plan effected by the February 22, 1994 amendment shall
apply only to stock options and stock appreciation rights granted under the Plan
from and after the February 22, 1994 effective date. All stock options and stock
appreciation rights which were issued and outstanding under the Plan immediately
prior to such effective date shall continue to be governed by the terms and
conditions of the Plan (and the instrument evidencing each such option or stock
appreciation right) as in effect on the date each such option or stock
appreciation right was previously granted, and none of the February 22, 1994
revisions to the Plan shall affect or otherwise modify the rights or obligations
of the holders of such options or stock appreciation rights with respect to the
acquisition of shares of Common Stock under those options or the exercise of
their stock

                                       12

appreciation rights. The revisions to the Plan effected by the March 11, 1996
amendment shall apply only to stock options and stock appreciation rights
granted under the Plan from and after the March 11, 1996 effective date. All
stock options and stock appreciation rights which were issued and outstanding
under the Plan immediately prior to such effective date shall continue to be
governed by the terms and conditions of the Plan (and the instrument evidencing
each such option or stock appreciation right) as in effect on the date each such
option or stock appreciation right was previously granted, and none of the March
11, 1996 revisions to the Plan shall affect or otherwise modify the rights or
obligations of the holders of such options or stock appreciation rights with
respect to the acquisition of shares of Common Stock under those options or the
exercise of their stock appreciation rights. The revisions to the Plan effected
by the April 24, 2000 amendment shall apply only to stock options and stock
appreciation rights granted under the Plan from and after the April 24, 2000
effective date. All stock options and stock appreciation rights which were
issued and outstanding under the Plan immediately prior to such effective date
shall continue to be governed by the terms and conditions of the Plan (and the
instrument evidencing each such option or stock appreciation right) as in effect
on the date each such option or stock appreciation right was previously granted,
and none of the April 24, 2000 revisions to the Plan shall affect or otherwise
modify the rights or obligations of the holders of such options or stock
appreciation rights with respect to the acquisition of shares of Common Stock
under those options or the exercise of their stock appreciation rights.

          (d)  TERM. Unless sooner terminated in accordance with Section X(a) of
the Plan, the Plan will terminate upon the earlier of (i) September 26, 2006 or
(ii) the date on which all shares available for issuance under the Plan shall
have been issued or cancelled pursuant to the exercise, surrender or cash-out of
options granted under the Plan. If the date of termination is determined under
clause (i) above, then options outstanding on such date will thereafter continue
to have force and effect in accordance with the provisions of the instruments
evidencing such options.

          (e)  EXCESS GRANTS. Options may be granted under this Plan to purchase
shares of Common Stock in excess of the number of shares then available for
issuance under the Plan, provided (i) an amendment to increase the maximum
number of shares issuable under the Plan is adopted by the Board prior to the
initial grant of any such option and within one year thereafter such amendment
is approved by the shareholders of the Corporation and (ii) each option so
granted is not to become exercisable, in whole or in part, at any time prior to
the obtaining of such shareholder approval.

XIV.      AMENDMENT OR DISCONTINUANCE.

          (a)  BOARD. The Board may amend, suspend or discontinue the Plan in
whole or in part at any time; provided, however, that (a) except to the extent
necessary to qualify as Incentive Options any or all options granted under the
Plan that are intended to so qualify, such action may not adversely affect
rights and obligations with respect to options outstanding under the Plan; (b)
the provisions of the Plan concerning the eligibility of non-employee members of
the Board for awards and the amount, price and timing of Automatic Option Grants
under this Plan may not be amended more than once every six months, other than

thereunder; and (c) the Board may not, without the

                                       13

approval of the Corporation's shareholders, (1) materially increase the number
of shares of Common Stock issuable under the Plan or increase the maximum number
of shares for which any one participant may be granted stock options and
separately exercisable stock appreciation rights after December 31, 1993 (unless
necessary to effect the adjustments required under Section IV(c)), (2)
materially modify the eligibility requirements for awards under the Plan, (3)
materially increase the benefits accruing to participants in the Plan or (4)
make any other change with respect to which the Board determines that
shareholder approval is required by applicable law or regulatory standards.

modify or waive any or all of the terms or restrictions applicable to any
outstanding option, to the extent not inconsistent with the Plan, including
(without limitation) the authority to accelerate the exercisability of one or
more outstanding options under the Plan upon such terms and conditions as the
Committee deems appropriate.

XV.       NO EMPLOYMENT OBLIGATION.

          Nothing contained in the Plan (or in any option granted under this
Plan) shall confer upon any employee, director, consultant or independent
contractor any right to continue in the employ of, or to provide services to,
the Corporation or any affiliate or constitute a contract or agreement of
employment or for the provision of services, or interfere in any way with the
right of the Corporation or an affiliate to reduce such employee's, consultant's
or independent contractor's compensation from the rate in existence at the time
of the granting of an option or to terminate such employee's, consultant's or
independent contractor's employment or services at any time, with or without
cause; but nothing contained in the Plan or in any option granted under this
Plan shall affect any contractual rights of an employee pursuant to a written
employment agreement.

XVI.      USE OF PROCEEDS.

          The cash proceeds received by the Corporation from the issuance of
shares pursuant to options under the Plan will be used for general corporate
purposes.

XVII.     COMPLIANCE.

          No option may be exercised, and the Corporation will not be obligated
to issue stock under any option unless, in the opinion of counsel for the
Corporation, such exercise and issuance is in compliance with all applicable
federal and state securities laws. As a condition to the grant of any option, or
to the issuance of stock under any option, the Committee may require that the
option holder agree to comply with such provisions of federal and state
securities laws as may be applicable to such grant, or to the sale of stock
acquired pursuant to the Plan, and that the option holder deliver to the
Corporation a written agreement, in form and substance satisfactory to the
Corporation and its counsel, implementing such agreement.
