                              BRIDGE LOAN AGREEMENT

                  This BRIDGE LOAN AGREEMENT is entered into as of April 23,
2002, among Mentor Graphics Corporation, an Oregon corporation (the "Company"),
the several financial institutions from time to time party to this Agreement
(collectively, the "Banks"; individually, a "Bank"), and Bank of America, N.A.,

                  WHEREAS, the Banks have agreed to make available to the
Company bridge loans upon the terms and conditions set forth in this Agreement;

                  NOW, THEREFORE, in consideration of the mutual agreements,
provisions and covenants contained herein, the parties agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

         1.01     Certain Defined Terms. The following terms have the following
                  meanings:

                  "Acquisition" means any transaction or series of related
         transactions for the purpose of or resulting, directly or indirectly,
         in (a) the acquisition of all or substantially all of the assets of a
         Person, or of any line of business or division of a Person; (b) the
         acquisition of in excess of 50% of the capital stock, partnership
         interests, membership interests or equity of any Person, or otherwise
         causing any Person to become a Subsidiary; or (c) a merger or
         consolidation or any other combination with another Person (other than
         a Person that is a Subsidiary) provided that the Company or the
         Subsidiary is the surviving entity.

                  "Affiliate" means, with respect to any Person, another Person
         that directly, or indirectly through one or more intermediaries,
         Controls or is Controlled by, or is under common Control with the
         Person specified. Control means the possession, directly or indirectly,
         of the power to direct or cause the direction of the management or

Base Rate Loans effective as of the expiration date of such Interest Period.

            (b) Interest on each Loan shall be paid in arrears on each Interest
Payment Date. Interest shall also be paid on the date of any prepayment of
Offshore Rate Loans under Section 2.06 for the portion of the Offshore Rate
Loans so prepaid and upon payment (including prepayment) in full thereof and,
during the existence of any Event of Default, interest shall be paid on demand
of the Agent at the request or with the consent of the Majority Banks.

            (c) Notwithstanding subsection (a) of this Section, if any amount of
principal of or interest on any Loan, or any other amount payable hereunder or
under any other Loan Document is not paid in full when due (whether at stated
maturity, by acceleration, demand or otherwise), the Company agrees to pay
interest on such unpaid principal or other amount, from the date such amount
becomes due until the date such amount is paid in full, and after as well as
before any entry of judgment thereon to the extent permitted by law, payable on
demand, at a fluctuating rate per annum equal to the Base Rate plus the
Applicable Margin, plus 2%.

            (d) Anything herein to the contrary notwithstanding, the obligations
of the Company to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for
or receiving such payment by such Bank would be contrary to the provisions of
any law applicable to such Bank limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Bank, and in such event
the Company shall pay such Bank interest at the highest rate permitted by
applicable law.

      2.09  Fees.

            (a) Agency and Other Fees. The Company shall (i) pay an agency fee
to the Agent for the Agent's own account, and (ii) pay certain other fees to the
Agent, in each case in the amounts and at the times specified in the Fee Letter.
Such fees shall be fully earned when paid and shall be nonrefundable for any
reason whatsoever.

            (b) Commitment Fees. The Company shall pay to the Agent for the
account of each Bank a commitment fee of 0.50% on the actual daily unused
portion of such Bank's


                                       23

Commitment, computed on a quarterly basis in arrears on the last Business Day of
each calendar quarter. Such commitment fee shall accrue from the earlier of (i)
the initial Borrowing Date, and (ii) July 1, 2002, to but excluding the
Termination Date and shall be due and payable quarterly in arrears on the last
Business Day of each calendar quarter during such period, with the final payment
to be made on the Termination Date. The commitment fees provided in this
subsection shall accrue at all times after the above-mentioned commencement
date, including at any time during which one or more conditions in Article IV
are not met.

      2.10  Computation of Fees and Interest.

            (a) All computations of interest for Base Rate Loans when the Base
Rate is determined by Bank of America's prime rate shall be made on the basis of
a year of 365 or 366 days, as the case may be, and actual days elapsed. All
other computations of fees and interest shall be made on the basis of a 360-day
year and actual days elapsed (which results in more interest being paid than if
computed on the basis of a 365-day year). Interest shall accrue on each Loan for
the day on which the Loan is made, and shall not accrue on a Loan, or any
portion thereof, for the day on which the Loan or such portion is paid; provided
that any Loan that is repaid on the same day on which it is made shall bear
interest for one day.

            (b) Each determination of an interest rate by the Agent shall be
conclusive and binding on the Company and the Banks in the absence of manifest
error. The Agent will, at the request of the Company or any Bank, deliver to the
Company or the Bank, as the case may be, a statement showing the quotations used
by the Agent in determining any interest rate and the resulting interest rate.

      2.11  Payments by the Company.

            (a) All payments to be made by the Company shall be made without
set-off, recoupment or counterclaim. Except as otherwise expressly provided
herein, all payments by the Company shall be made to the Agent for the account
of the Banks at the Agent's Payment Office, and shall be made in dollars and in
immediately available funds, no later than 11:00 a.m. (San Francisco time) on
the date specified herein. The Agent will promptly distribute to each Bank its
Pro Rata Share (or other applicable share as expressly provided herein) of such
payment in like funds as received. Any payment received by the Agent later than
11:00 a.m. (San Francisco time) shall be deemed to have been received on the
following Business Day and any applicable interest or fee shall continue to
accrue.

            (b) Subject to the provisions set forth in the definition of
"Interest Period" herein, whenever any payment is due on a day other than a
Business Day, such payment shall be made on the following Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be.

            (c) Unless the Agent receives notice from the Company prior to the
date on which any payment is due to the Banks that the Company will not make
such payment in full as and when required, the Agent may assume that the Company
has made such payment in full to the Agent on such date in immediately available
funds and the Agent may (but shall not be so required), in reliance upon such
assumption, distribute to each Bank on such due date an amount


                                       24

equal to the amount then due such Bank. If and to the extent the Company has not
made such payment in full to the Agent, each Bank shall repay to the Agent on
demand such amount distributed to such Bank, together with interest thereon at
the Federal Funds Rate for each day from the date such amount is distributed to
such Bank until the date repaid.

      2.12  Payments by the Banks to the Agent.

            (a) Unless the Agent receives notice from a Bank on or prior to the
Closing Date or, with respect to any Borrowing after the Closing Date, at least
one Business Day prior to the date of such Borrowing, that such Bank will not
make available as and when required hereunder to the Agent for the account of
the Company the amount of that Bank's Pro Rata Share of the Borrowing, the Agent
may assume that each Bank has made such amount available to the Agent in
immediately available funds on the Borrowing Date and the Agent may (but shall
not be so required), in reliance upon such assumption, make available to the
Company on such date a corresponding amount. If and to the extent any Bank shall
not have made its full amount available to the Agent in immediately available
funds and the Agent in such circumstances has made available to the Company such
amount, that Bank shall on the Business Day following such Borrowing Date make
such amount available to the Agent, together with interest at the Federal Funds
Rate for each day during such period. A notice of the Agent submitted to any
Bank with respect to amounts owing under this subsection (a) shall be
conclusive, absent manifest error. If such amount is so made available, such
payment to the Agent shall constitute such Bank's Loan on the date of Borrowing
for all purposes of this Agreement. If such amount is not made available to the
Agent on the Business Day following the Borrowing Date, the Agent will notify
the Company of such failure to fund and, upon demand by the Agent, the Company
shall pay such amount to the Agent for the Agent's account, together with
interest thereon for each day elapsed since the date of such Borrowing, at a
rate per annum equal to the interest rate applicable at the time to the Loans
comprising such Borrowing. Such payment by the Company to the Agent shall be
without prejudice to the Company's rights, if any, against the Bank which failed
to fund.

            (b) The failure of any Bank to make any Loan on any Borrowing Date
shall not relieve any other Bank of any obligation hereunder to make a Loan on
such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.

      2.13  Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from the purchasing
Bank, such purchase shall to that extent be rescinded and each other Bank shall
repay to the purchasing Bank the purchase price paid therefor, together with an
amount equal to such paying Bank's ratable share (according to the proportion of
(i) the amount of such paying Bank's required repayment to (ii) the total amount
so recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in


                                       25

respect of the total amount so recovered. The Company agrees that any Bank so
purchasing a participation from another Bank may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to Section 10.09) with respect to such participation as
fully as if such Bank were the direct creditor of the Company in the amount of
such participation. The Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Banks following any such purchases or
repayments.

                                   ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

      3.01  Taxes.

            (a) Any and all payments by the Company to each Bank or the Agent
under this Agreement and any other Loan Document shall be made free and clear
of, and without deduction or withholding for, any Taxes. In addition, the
Company shall pay all Other Taxes.

            (b) If the Company shall be required by law to deduct or withhold
any Taxes, Other Taxes or Further Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then:

                  (i)   the sum payable shall be increased as necessary so that,
      after making all required deductions and withholdings (including
      deductions and withholdings applicable to additional sums payable under
      this Section), such Bank or the Agent, as the case may be, receives and
      retains an amount equal to the sum it would have received and retained had
      no such deductions or withholdings been made;

                  (ii)  the Company shall make such deductions and withholdings;

                  (iii) the Company shall pay the full amount deducted or
      withheld to the relevant taxing authority or other authority in accordance
      with applicable law; and

                  (iv)  the Company shall also pay to each Bank or the Agent for
      the account of such Bank, at the time interest is paid, Further Taxes in
      the amount that the respective Bank specifies as necessary to preserve the
      after-tax yield the Bank would have received if such Taxes, Other Taxes or
      Further Taxes had not been imposed.

            (c) The Company agrees to indemnify and hold harmless each Bank and
the Agent for the full amount of (i) Taxes, (ii) Other Taxes, and (iii) Further
Taxes in the amount that the respective Bank specifies as necessary to preserve
the after-tax yield the Bank would have received if such Taxes, Other Taxes or
Further Taxes had not been imposed, and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not such Taxes, Other Taxes or Further Taxes were correctly
or legally asserted. Payment under this indemnification shall be made within 30
days after the date the Bank or the Agent makes written demand therefor.



                                       26

            (d) Within 30 days after the date of any payment by the Company of
Taxes, Other Taxes or Further Taxes, the Company shall furnish to each Bank or
the Agent the original or a certified copy of a receipt evidencing payment
thereof, or other evidence of payment satisfactory to such Bank or the Agent.

            (e) If the Company is required to pay any amount to any Bank or the
Agent pursuant to subsection (b) or (c) of this Section, then such Bank shall
use reasonable efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue, if such change in
the sole judgment of such Bank is not otherwise disadvantageous to such Bank.

      3.02  Illegality.

            (a) If any Bank determines that the introduction of any Requirement
of Law, or any change in any Requirement of Law, or in the interpretation or
administration of any Requirement of Law, has made it unlawful, or that any
central bank or other Governmental Authority has asserted that it is unlawful,
for any Bank or its applicable Lending Office to make Offshore Rate Loans, then,
on notice thereof by the Bank to the Company through the Agent, any obligation
of that Bank to make Offshore Rate Loans shall be suspended until the Bank
notifies the Agent and the Company that the circumstances giving rise to such
determination no longer exist.

            (b) If a Bank determines that it is unlawful to maintain any
Offshore Rate Loan, the Company shall, upon its receipt of notice of such fact
and demand from such Bank (with a copy to the Agent), prepay in full such
Offshore Rate Loans of that Bank then outstanding, together with interest
accrued thereon and amounts required under Section 3.04, either on the last day
of the Interest Period thereof, if the Bank may lawfully continue to maintain
such Offshore Rate Loans to such day, or immediately, if the Bank may not
lawfully continue to maintain such Offshore Rate Loan. If the Company is
required to so prepay any Offshore Rate Loan, then concurrently with such
prepayment, the Company shall borrow from the affected Bank, in the amount of
such repayment, a Base Rate Loan.

            (c) If the obligation of any Bank to make or maintain Offshore Rate
Loans has been so terminated or suspended, the Company may elect, by giving
notice to the Bank through the Agent that all Loans which would otherwise be
made by the Bank as Offshore Rate Loans shall be instead Base Rate Loans.

            (d) Before giving any notice to the Agent under this Section, the
affected Bank shall designate a different Lending Office with respect to its
Offshore Rate Loans if such designation will avoid the need for giving such
notice or making such demand and will not, in the judgment of the Bank, be
illegal or otherwise disadvantageous to the Bank.

      3.03  Increased Costs and Reduction of Return.

            (a) If any Bank determines that, due to either (i) the introduction
of or any change (other than any change by way of imposition of or increase in
reserve requirements included in the calculation of the Offshore Rate) in or in
the interpretation of any law or regulation, or (ii) the compliance by that Bank
with any guideline or request from any central bank or other


                                       27

Governmental Authority (whether or not having the force of law), there shall be
any increase in the cost to such Bank of agreeing to make or making, funding or
maintaining any Offshore Rate Loans, then the Company shall be liable for, and
shall from time to time, upon demand (with a copy of such demand to be sent to
the Agent), pay to the Agent for the account of such Bank, additional amounts as
are sufficient to compensate such Bank for such increased costs; provided,
however, that (x) this subsection 3.03(a) shall not apply to matters covered by
Section 3.01 and (y) any increase, subsequent to the date a Bank (or the Agent)
became a party to this Agreement, in the rate or basis of computation of any tax
imposed on or measured by its net income by the jurisdiction (or any political
subdivisions thereof) under the laws of which such Bank or the Agent, as the
case may be, is organized or maintains a lending office shall not result in
increased costs for purposes of this subsection 3.03(a).

            (b) If any Bank shall have determined that (i) the introduction of
any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy
Regulation, (iii) any change in the interpretation or administration of any
Capital Adequacy Regulation by any central bank or other Governmental Authority
charged with the interpretation or administration thereof, or (iv) compliance by
the Bank (or its Lending Office) or any corporation controlling the Bank with
any Capital Adequacy Regulation, affects or would affect the amount of capital
required or expected to be maintained by the Bank or any corporation controlling
the Bank and (taking into consideration such Bank's or such corporation's
policies with respect to capital adequacy and such Bank's desired return on
capital) determines that the amount of such capital is increased as a
consequence of its Commitment, loans, credits or obligations under this
Agreement, then, upon demand of such Bank to the Company through the Agent, the
Company shall pay to the Bank, from time to time as specified by the Bank,
additional amounts sufficient to compensate the Bank for such increase.

      3.04  Funding Losses. The Company shall reimburse each Bank and hold each
Bank harmless from any loss or expense which the Bank may sustain or incur as a
consequence of:

            (a) the failure of the Company to make on a timely basis any payment
of principal of any Offshore Rate Loan;

            (b) the failure of the Company to borrow, continue or convert a Loan
after the Company has given (or is deemed to have given) a Notice of Borrowing
or a Notice of Conversion/Continuation;

            (c) the failure of the Company to make any prepayment in accordance
with any notice delivered under Section 2.06;

            (d) the prepayment (including pursuant to Section 2.06) or other
payment (including after acceleration thereof) of an Offshore Rate Loan on a day
that is not the last day of the relevant Interest Period; or

            (e) the automatic conversion under the proviso of subsection 2.04(a)
of any Offshore Rate Loan to a Base Rate Loan on a day that is not the last day
of the relevant Interest Period;



                                       28

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained. For purposes of
calculating amounts payable by the Company to the Banks under this Section and
under subsection 3.03(a), each Offshore Rate Loan made by a Bank (and each
related reserve, special deposit or similar requirement) shall be conclusively
deemed to have been funded at the LIBOR used in determining the Offshore Rate
for such Offshore Rate Loan by a matching deposit or other borrowing in the
interbank Eurodollar market for a comparable amount and for a comparable period,
whether or not such Offshore Rate Loan is in fact so funded.

      3.05  Inability to Determine Rates. If the Agent determines that for any
reason adequate and reasonable means do not exist for determining the Offshore
Rate for any requested Interest Period with respect to a proposed Offshore Rate
Loan, or that the Offshore Rate applicable pursuant to subsection 2.08(a) for
any requested Interest Period with respect to a proposed Offshore Rate Loan does
not adequately and fairly reflect the cost to the Banks of funding such Loan,
the Agent will promptly so notify the Company and each Bank. Thereafter, the
obligation of the Banks to make or maintain Offshore Rate Loans, as the case may
be, hereunder shall be suspended until the Agent revokes such notice in writing.
Upon receipt of such notice, the Company may revoke any Notice of Borrowing or
Notice of Conversion/Continuation then submitted by it. If the Company does not
revoke such Notice, the Banks shall make, convert or continue the Loans, as
proposed by the Company, in the amount specified in the applicable notice
submitted by the Company, but such Loans shall be made, converted or continued
as Base Rate Loans instead of Offshore Rate Loans.

      3.06  Reserves on Offshore Rate Loans. The Company shall pay to each Bank,
as long as such Bank shall be required under regulations of the FRB to maintain
reserves with respect to liabilities or assets consisting of or including
Eurocurrency funds or deposits (currently known as "Eurocurrency liabilities"),
additional costs on the unpaid principal amount of each Offshore Rate Loan equal
to the actual costs of such reserves allocated to such Loan by the Bank (as
determined by the Bank in good faith, which determination shall be conclusive
absent manifest error), payable on each date on which interest is payable on
such Loan, provided the Company shall have received at least 15 days' prior
written notice (with a copy to the Agent) of such additional interest from the
Bank. If a Bank fails to give notice 15 days prior to the relevant Interest
Payment Date, such additional interest shall be payable 15 days from receipt of
such notice.

      3.07  Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Company (with a copy to
the Agent) a certificate setting forth in reasonable detail the amount payable
to the Bank hereunder and such certificate shall be conclusive and binding on
the Company in the absence of manifest error.

      3.08  Delay. Failure or delay on the part of any Bank to demand
compensation under this Article III shall not constitute a waiver of such Bank's
right to demand such compensation; provided, that no Bank shall be entitled to
compensation under this Article III for any increased costs or reductions
incurred or suffered with respect to any date unless such Bank shall have
notified the Company not more than 90 days after the later of (a) such date and
(b) the date on which such Bank shall have become aware of such costs or
reductions.



                                       29

      3.09  Substitution of Banks. Upon the receipt by the Company from any Bank
(an "Affected Bank") of a claim for compensation under Section 3.03 or if the
Company is required to pay any amount to any Affected Bank or the Agent for the
account of an Affected Bank pursuant to subsection 3.01(b) or 3.01(c) and such
Affected Bank has not changed the jurisdiction of its Lending Office so as to
eliminate such additional payment by the Company within 30 days after a request
by the Company to effect such change, the Company may: (i) request the Affected
Bank to use its best efforts to obtain a replacement bank or financial
institution satisfactory to the Company (which shall, in any event, be an
Eligible Assignee) to acquire and assume all or a ratable part of all of such
Affected Bank's Loans and Commitment (a "Replacement Bank"), (ii) request one or
more of the other Banks to acquire and assume all or part of such Affected
Bank's Loans and Commitment, or (iii) designate a Replacement Bank. Any such
designation of a Replacement Bank under clause (i) or (iii) or of an existing
Bank under clause (ii) shall be subject to the prior written consent of the
Agent (which consent shall not be unreasonably withheld or delayed), and shall
be effected in accordance with all requirements for an assignment set forth in
Section 10.07 hereof. Without limiting the generality of the foregoing, the
Company agrees to pay to each Affected Bank any amounts arising under Section
3.04 by virtue of such Affected Bank's replacement on a date other than the last
day of an Interest Period, with respect to any Offshore Rate Loans then
outstanding.

      3.10  Survival. The agreements and obligations of the Company in this
Article III shall survive the payment of all other Obligations.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

its initial Loan) or to


                                       31

and correct as of such earlier date); and

            (c) No Existing Default. No Default or Event of Default shall exist

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

            The Company represents and warrants to the Agent and each Bank that:

      5.01  Corporate Existence and Power. The Company and each of its Material
Subsidiaries:



                                       32

            (a) is an entity duly organized, validly existing and, if applicable
in such jurisdiction, in good standing under the laws of the jurisdiction of its
incorporation or other establishment;

            (b) has (i) the power and authority and (ii) all governmental
licenses, authorizations, consents and approvals, in each case, to own its
assets, carry on its business and to execute, deliver, and perform its
obligations under the Loan Documents to which it is a party;

            (c) is duly qualified as a foreign corporation or other entity and
is licensed and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification or license; and

            (d) is in compliance with all Requirements of Law; except, in each
case referred to in clause (b)(ii), clause (c) or clause (d), to the extent that
the failure to do so is not reasonably expected to have a Material Adverse
Effect.

      5.02  Corporate Authorization; No Contravention. The execution, delivery
and performance by the Company of this Agreement and each other Loan Document to
which the Company is party, have been duly authorized by all necessary corporate
action, and do not and will not:

            (a) contravene the terms of any of the Company's Organization
Documents;

            (b) conflict with or result in any breach or contravention of, or
the creation of any Lien under, any document evidencing any Contractual
Obligation to which the Company is a party or any order, injunction, writ or
decree of any Governmental Authority to which the Company or its property is
subject; or

            (c) violate any Requirement of Law;

            except, in each case referred to in the foregoing clauses (b) and
(c), where the conflict, breach, contravention, creation or violation would not
reasonably be expected to have a Material Adverse Effect.

      5.03  Governmental Authorization. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, the Company of
this Agreement or any other Loan Document.

      5.04  Binding Effect. This Agreement and each other Loan Document to which
the Company is a party constitute the legal, valid and binding obligations of
the Company, enforceable against the Company in accordance with their respective
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, or similar laws affecting the enforcement of creditors' rights
generally or by equitable principles relating to enforceability.

      5.05  Litigation. Except as specifically disclosed in Schedule 5.05, there
are no actions, suits, proceedings, claims or disputes pending, or to the best
knowledge of the Company,


                                       33

threatened or contemplated, at law, in equity, in arbitration or before any
Governmental Authority, against the Company, or its Subsidiaries or any of their
respective properties which:

            (a) purport to affect or pertain to this Agreement or any other Loan
Document, or any of the transactions contemplated hereby or thereby; or

            (b) would reasonably be expected to have a Material Adverse Effect.
No injunction, writ, temporary restraining order or any order of any nature has
been issued by any court or other Governmental Authority purporting to enjoin or
restrain the execution, delivery or performance of this Agreement or any other
Loan Document, or directing that the transactions provided for herein or therein
not be consummated as herein or therein provided.

      5.06  No Default. No Default or Event of Default exists or would result
from the incurring of any Obligations by the Company. As of the Closing Date,
neither the Company nor any Subsidiary is in default under or with respect to
any Contractual Obligation in any respect which, individually or together with
all such defaults, could reasonably be expected to have a Material Adverse
Effect, or that would, if such default had occurred after the Closing Date,
create an Event of Default under subsection 8.01(e).

      5.07  ERISA Compliance. Except as specifically disclosed in Schedule 5.07:

            (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other applicable federal or state
law, except to the extent that the failure to comply is not reasonably expected
to have a Material Adverse Effect. Each Plan which is intended to qualify under
Section 401(a) of the Code has received or has applied for when due and not been
denied a favorable determination letter from the IRS and to the best knowledge
of the Company, nothing has occurred which would cause the loss of such
qualification. The Company and each ERISA Affiliate has made or duly provided
for all required contributions to any Plan subject to Section 412 of the Code,
and no application for a funding waiver or an extension of any amortization
period pursuant to Section 412 of the Code has been made with respect to any
Plan.

            (b) There are no pending or, to the best knowledge of Company,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan which has resulted or could reasonably be expected to
result in a Material Adverse Effect. There has been no prohibited transaction or
violation of the fiduciary responsibility rules with respect to any Plan which
has resulted or could reasonably be expected to result in a Material Adverse
Effect.

            (c) (i) No ERISA Event has occurred or is reasonably expected to
occur, (ii) no Pension Plan has any Unfunded Pension Liability, (iii) neither
the Company nor any ERISA Affiliate has incurred, or reasonably expects to
incur, any liability under Title IV of ERISA with respect to any Pension Plan
(other than premiums due and not delinquent under Section 4007 of ERISA), (iv)
neither the Company nor any ERISA Affiliate has incurred, or reasonably expects
to incur, any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under
Section 4201 or 4243 of ERISA


                                       34

with respect to a Multiemployer Plan, and (v) neither the Company nor any ERISA
Affiliate has engaged in a transaction that could be subject to Section 4069 or
4212(c) of ERISA.

      5.08  Use of Proceeds; Margin Regulations. The proceeds of the Loans are
to be used solely for the purposes set forth in and permitted by Section 6.12
and Section 7.07. Neither the Company nor any Subsidiary is generally engaged in
the business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock.

      5.09  Title to Properties. The Company and each Subsidiary have good
record and marketable title in fee simple to, or valid leasehold interests in,
all real property necessary or used in the ordinary conduct of their respective
businesses, except for such defects in title as could not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect. As of
the Closing Date, the real and personal property of the Company and its Material
Subsidiaries is subject to no Liens, other than Permitted Liens.

      5.10  Taxes. The Company and its Subsidiaries have filed all Federal and
other material tax returns and reports required to be filed, and have paid all
Federal and other material taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets
otherwise due and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided in
accordance with GAAP. To the best knowledge of the Company, there is no proposed
tax assessment against the Company or any Subsidiary that would, if made, have a
Material Adverse Effect.

      5.11  Financial Condition.

            (a) The audited consolidated balance sheets of the Company and its
Subsidiaries as of December 31, 2001, and the related consolidated statements of
operations and cash flows for the fiscal year ended on that date:

                  (i)   were prepared in accordance with GAAP consistently
      applied throughout the period covered thereby, except as otherwise
      expressly noted therein;

                  (ii)  fairly present the financial condition of the Company
      and its Subsidiaries as of the date thereof and results of operations for
      the period covered thereby; and

                  (iii) reflect or disclose all material Indebtedness and other
      liabilities of the Company and its consolidated Subsidiaries as of the
      date thereof, including liabilities for taxes, material commitments and
      Contingent Obligations.

            (b) Since December 31, 2001, there has been no Material Adverse
Effect.

      5.12  Environmental Matters. The Company conducts in the ordinary course
of business a review of the effect of existing Environmental Laws and existing
Environmental Claims on its business, operations and properties, and as a result
thereof the Company has reasonably concluded that, except as specifically
disclosed in Schedule 5.12, such Environmental


                                       35

Laws and Environmental Claims are not, individually or in the aggregate,
reasonably expected to have a Material Adverse Effect.

      5.13  Regulated Entities. None of the Company, any Person controlling the
Company, or any Subsidiary, is an "Investment Company" within the meaning of the
Investment Company Act of 1940. The Company is not subject to regulation under
the Public Utility Holding Company Act of 1935, the Federal Power Act, the
Interstate Commerce Act, any state public utilities code, or any other Federal
or state statute or regulation limiting its ability to incur Indebtedness.

      5.14  No Burdensome Restrictions. Neither the Company nor any Subsidiary
is a party to or bound by any Contractual Obligation, or subject to any
restriction in any Organization Document, or any Requirement of Law, which could
reasonably be expected to have a Material Adverse Effect.

      5.15  Copyrights, Patents, Trademarks and Licenses, etc. Except as
disclosed on Schedule 5.15, the Company or its Subsidiaries own or are licensed
or otherwise have the right to use all of the patents, trademarks, service
marks, trade names, copyrights, contractual franchises, authorizations and other
rights that are reasonably necessary for the operation of their respective
businesses, without conflict with the rights of any other Person. To the best
knowledge of the Company, no slogan or other advertising device, product,
process, method, substance, part or other material now employed, or now
contemplated to be employed, by the Company or any Subsidiary infringes upon any
rights held by any other Person. Except as specifically disclosed in Schedule
5.05, no claim or litigation regarding any of the foregoing is pending or
threatened, and no patent, invention, device, application, principle or any
statute, law, rule, regulation, standard or code is pending or, to the knowledge
of the Company, proposed, which, in either case, could reasonably be expected to
have a Material Adverse Effect.

      5.16  Subsidiaries As of the Closing Date, the Company has no Subsidiaries
other than those specifically disclosed in part (a) of Schedule 5.16 and has no
material equity investments in any other corporation or entity other than those
specifically disclosed in part (b) of Schedule 5.16.

      5.17  Insurance. Except as specifically disclosed in Schedule 5.17, the
properties of the Company and its Subsidiaries are insured with financially
sound and reputable insurance companies not Affiliates of the Company, in such
amounts, with such deductibles and covering such risks as are customarily
carried by companies engaged in similar businesses and owning similar properties
in localities where the Company or such Subsidiary operates.

      5.18  Swap Obligations. Neither the Company nor any of its Subsidiaries
has incurred any outstanding obligations under any Swap Contracts, other than
Permitted Swap Obligations. The Company has undertaken its own independent
assessment of its consolidated assets, liabilities and commitments and has
considered appropriate means of mitigating and managing risks associated with
such matters and has not relied on any swap counterparty or any Affiliate of any
swap counterparty in determining whether to enter into any Swap Contract.



                                       36

      5.19  Full Disclosure. None of the representations or warranties made by
the Company or any Subsidiary in the Loan Documents as of the date such
representations and warranties are made or deemed made, and none of the
statements contained in any exhibit, report, statement or certificate furnished
by or on behalf of the Company or any Subsidiary in connection with the Loan
Documents (including the offering and disclosure materials delivered by or on
behalf of the Company to the Banks prior to the Closing Date), contains any
untrue statement of a material fact or omits any material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances under which they are made, not misleading as of the time when made
or delivered.

                                   ARTICLE VI

                              AFFIRMATIVE COVENANTS

            (a) of the occurrence of any Default or Event of Default;

            (b) as soon as a Responsible Officer becomes aware thereof, of any

Obligation of the Company or any Subsidiary, (ii) any dispute, litigation,

            (c) of the occurrence of any of the following events affecting the

amendments and supplements thereto to the extent not previously delivered to the
Agent pursuant to Sections 4.01 and 4.03; and

statement by a Responsible Officer setting forth details of the occurrence
referred to therein, and stating what action the Company or any affected
Subsidiary proposes to take with respect thereto and at what time. Each notice
under subsection 6.03(a) shall describe with particularity any and all clauses
or provisions of this Agreement or other Loan Document that have been breached
or violated, but the reasonable failure to identify all such clauses or
provisions shall not, of itself, constitute a failure to comply with subsection
6.03(a).

      6.05  Maintenance of Property. The Company shall, and shall cause each

incidents or conditions, of $20,000,000 or more, and the same shall remain
unsatisfied, unvacated and unstayed pending appeal for a period of 10 days after
the entry thereof; or

            (l) Adverse Change. There occurs a Material Adverse Effect; or

            (m) Invalidity of Subordination Provisions. The subordination
provisions of any agreement or instrument governing any Indebtedness which is
subordinated to the Indebtedness hereunder is for any reason revoked,

Company or any Subsidiary, or the Company or any Subsidiary otherwise contests
in any manner the validity or enforceability thereof or denies that it has any
further liability or obligation thereunder.

      8.02  Remedies. If any Event of Default occurs, the Agent shall, at the
request of, or may, with the consent of, the Majority Banks,

            (a) declare the commitment of each Bank to make Loans to be
terminated, whereupon such commitments shall be terminated;

            (b) declare the unpaid principal amount of all outstanding Loans,
all interest accrued and unpaid thereon, and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due and payable,
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by the Company; and

            (c) exercise on behalf of itself and the Banks all rights and
remedies available to it and the Banks under the Loan Documents or applicable
law;

provided, however, that upon the occurrence of any event specified in subsection
(f) or (g) of Section 8.01 (in the case of clause (i) of subsection (g) upon the
expiration of the 60-day period mentioned therein), the obligation of each Bank
to make Loans shall automatically terminate and the unpaid principal amount of
all outstanding Loans and all interest and other amounts as aforesaid shall
automatically become due and payable without further act of the Agent or any
Bank.

      8.03  Rights Not Exclusive. The rights provided for in this Agreement and
the other Loan Documents are cumulative and are not exclusive of any other
rights, powers, privileges or remedies provided by law or in equity, or under
any other instrument, document or agreement now existing or hereafter arising.

                                   ARTICLE IX

                                    THE AGENT

      9.01  Appointment and Authorization of Agent. Each Bank hereby irrevocably
appoints, designates and authorizes the Agent to take such action on its behalf
under the provisions of this Agreement and each other Loan Document and to
exercise such powers and perform such duties as are expressly delegated to it by
the terms of this Agreement or any other Loan Document, together with such
powers as are reasonably incidental thereto. Notwithstanding any provision to
the contrary contained elsewhere herein or in any other Loan


                                       53

Document, the Agent shall not have any duties or responsibilities, except those
expressly set forth herein, nor shall the Agent have or be deemed to have any
fiduciary relationship with any Bank or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Agent. Without limiting the generality of the foregoing sentence, the use of the
term "agent" herein and in the other Loan Documents with reference to the Agent
is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable law. Instead, such
term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting
parties.

      9.02  Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. The
Agent shall not be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct.

      9.03  Liability of Agent. No Agent-Related Person shall (a) be liable for
any action taken or omitted to be taken by any of them under or in connection
with this Agreement or any other Loan Document or the transactions contemplated
hereby (except for its own gross negligence or willful misconduct in connection
with its duties expressly set forth herein); or (b) be responsible in any manner
to any Bank or participant for any recital, statement, representation or
warranty made by the Company or any Subsidiary or Affiliate of the Company or
any officer thereof, contained herein or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document, or for any failure
of the Company or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Bank or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Company or any Affiliate thereof.

      9.04  Reliance by Agent.

            (a) The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to the Company), independent accountants and
other experts selected by the Agent. The Agent shall be fully justified in
failing or refusing to take any action under any Loan Document unless it shall
first receive such advice or concurrence of the Majority Banks as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or


                                       54

in refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Majority Banks or all the Banks, if
required hereunder, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Banks and participants. Where
this Agreement expressly permits or prohibits an action unless the Majority
Banks otherwise determine, the Agent shall, and in all other instances, the
Agent may, but shall not be required to, initiate any solicitation for the
consent or a vote of the Banks.

            (b) For purposes of determining compliance with the conditions
specified in Section 4.01, each Bank that has signed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Bank for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Bank.

      9.05  Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Agent for the account of the Banks, unless the Agent shall have
received written notice from a Bank or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default." The Agent will notify the Banks of its receipt of any such
notice. The Agent shall take such action with respect to such Default or Event
of Default as may be directed by the Majority Banks in accordance with Article
VIII; provided, however, that unless and until the Agent has received any such
direction, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Banks.

      9.06  Credit Decision; Disclosure of Information by Agent. Each Bank
acknowledges that no Agent-Related Person has made any representation or
warranty to it, and that no act by the Agent hereafter taken, including any
consent to and acceptance of any assignment or review of the affairs of the
Company and its Subsidiaries or any Affiliate thereof, shall be deemed to
constitute any representation or warranty by any Agent-Related Person to any
Bank as to any matter, including whether Agent-Related Persons have disclosed
material information in their possession. Each Bank represents to the Agent that
it has, independently and without reliance upon any Agent-Related Person and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company and
its respective Subsidiaries, and all applicable bank or other regulatory laws
relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to the Company. Each Bank also
represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Company. Except for notices,
reports and other documents expressly required to be furnished to the Banks by
the Agent herein, the Agent shall not have any duty or responsibility to provide
any Bank with any credit or other information concerning the business,
prospects, operations, property, financial and


                                       55

other condition or creditworthiness of the Company, its Subsidiaries or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

      9.07  Indemnification of Agent. Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand each
Agent-Related Person (to the extent not reimbursed by or on behalf of the
Company and without limiting the obligation of the Company to do so), pro rata,
and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided, however, that no Bank shall be
liable for the payment to any Agent-Related Person of any portion of such
Indemnified Liabilities to the extent determined in a final, nonappealable
judgment by a court of competent jurisdiction to have resulted from such
Person's own gross negligence or willful misconduct; provided, however, that no
action taken in accordance with the directions of the Majority Banks shall be
deemed to constitute gross negligence or willful misconduct for purposes of this
Section. Without limitation of the foregoing, each Bank shall reimburse the
Agent upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by the Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,
any other Loan Document, or any document contemplated by or referred to herein,
to the extent that the Agent is not reimbursed for such expenses by or on behalf
of the Company. The undertaking in this Section shall survive termination of the
Commitments, the payment of all Obligations hereunder and the resignation of the
Agent.

      9.08  Agent in its Individual Capacity. The Agent and its Affiliates may
make loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company, its
Subsidiaries and each of their respective Affiliates as though the Agent were
not the Agent hereunder and without notice to or consent of the Banks. The Banks
acknowledge that, pursuant to such activities, the Agent or its Affiliates may
receive information regarding the Company or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Company or such Affiliate) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans, the
Agent shall have the same rights and powers under this Agreement as any other
Bank and may exercise such rights and powers as though it were not the Agent and
the terms "Bank" and "Banks" include the Agent in its individual capacity.

      9.09  Successor Agent. The Agent may resign as Agent upon 30 days' notice
to the Banks. If the Agent resigns under this Agreement, the Majority Banks
shall appoint from among the Banks a successor Agent for the Banks which
successor Agent shall be consented to by the Company at all times other than
during the existence of an Event of Default (which consent of the Company shall
not be unreasonably withheld or delayed). If no successor Agent is appointed
prior to the effective date of the resignation of the Agent, the Agent may
appoint, after consulting with the Banks and the Company, a successor Agent from
among the Banks. Upon the acceptance of its appointment as successor Agent
hereunder, the Person acting as such successor Agent shall succeed to all the
rights, powers and duties of the retiring Agent and the respective terms
"Agent," shall mean such successor Agent and the retiring Agent's appointment,
powers and duties as Agent shall be terminated. After any retiring Agent's
resignation hereunder as


                                       56

Agent, the provisions of this Article IX and Sections 10.04 and 10.05 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement. If no successor Agent has accepted
appointment as Agent by the date which is 30 days following a retiring Agent's
notice of resignation, the retiring Agent's resignation shall nevertheless
thereupon become effective and the Banks shall perform all of the duties of the
Agent hereunder until such time, if any, as the Majority Banks appoint a
successor agent as provided for above.

                                    ARTICLE X

                                  MISCELLANEOUS

      10.01 Amendments, Etc. No amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by the
Company therefrom, shall be effective unless in writing signed by the Majority
Banks and the Company and acknowledged by the Agent, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no such amendment, waiver or
consent shall, unless in writing and signed by each of the Banks directly
affected thereby and by the Company, and acknowledged by the Agent, do any of
the following:

            (a) extend or increase the Commitment of any Bank (or reinstate any
Commitment terminated pursuant to Section 8.02);

            (b) postpone any date fixed by this Agreement or any other Loan
Document for any payment or mandatory prepayment of principal, interest, fees or
other amounts due to the Banks (or any of them) hereunder or under any other
Loan Document;

            (c) reduce the principal of, or the rate of interest specified
herein on, any Loan or (subject to clause (ii) of the proviso below) any fees or
other amounts payable hereunder or under any other Loan Document, or change the
manner of computation of any financial covenant to the extent used in
determining the Applicable Margin that would result in a reduction of any
interest rate on any Loan; provided, however, that only the consent of the
Majority Banks shall be necessary to amend the definition of "Default Rate" or
to waive any obligation of the Company to pay interest at the Default Rate;

            (d) change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which is required for the Banks or any of
them to take any action hereunder; or

            (e) amend this Section, or Section 2.13, or any provision herein
providing for consent or other action by all the Banks;

and; provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks or each
directly-affected Bank, as the case may be, affect the rights or duties of the
Agent under this Agreement or any other Loan Document, and (ii) the Fee Letter
may be amended, or rights or privileges thereunder waived, in a writing executed
only by the respective parties thereto. Notwithstanding anything to the contrary
herein, any Bank that has failed to fund any portion of the Commitment on any
Borrowing Date, shall not have any right to approve or disapprove any amendment,
waiver or


                                       57

consent hereunder, except that the Pro Rata Share of such Bank may not be
increased without the consent of such Bank.

      10.02 Notices and Other Communications; Facsimile Copies.

            (a) General. Unless otherwise expressly provided herein, all notices
and other communications provided for hereunder shall be in writing (including
by facsimile transmission) and mailed, faxed or delivered, to the address,
facsimile number or (subject to subsection (c) below) electronic mail address
specified for notices on Schedule 10.02; or, in the case of the Company or the
Agent, to such other address as shall be designated by such party in a notice to
the other parties, and in the case of any other party, to such other address as
shall be designated by such party in a notice to the Company and the Agent. All
such notices and other communications shall be deemed to be given or made upon
the earlier to occur of (i) actual receipt by the intended recipient, and (ii)
(A) if delivered by hand or by courier, when signed for by the intended
recipient; (B) if delivered by mail, four Business Days after deposit in the
mails, postage prepaid; (C) if delivered by facsimile, when sent and receipt has
been confirmed by telephone (on a Business Day); and (D) if delivered by
electronic mail (which form of delivery is subject to the provisions of
subsection (c) below), when delivered; provided, however, that notices and other
communications to the Agent shall not be effective until actually received by
the Agent. Any notice or other communication permitted to be given, made or
confirmed by telephone hereunder shall be given, made or confirmed by means of a
telephone call to the intended recipient at the number specified on Schedule
10.02, it being understood and agreed that a voicemail message shall in no event
be effective as a notice, communication or confirmation hereunder.

            (b) Effectiveness of Facsimile Documents and Signatures. Loan
Documents may be transmitted and/or signed by facsimile. The effectiveness of
any such documents and signatures shall, subject to applicable law, have the
same force and effect as manually-signed originals and shall be binding on the
Company, the Agent and the Banks. The Agent may also require that any such
documents and signatures be confirmed by a manually-signed original thereof;
provided, however, that the failure to request or deliver the same shall not
limit the effectiveness of any facsimile document or signature.

            (c) Limited Use of Electronic Mail. Electronic mail and Internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information as provided in Section 6.02, and to
distribute Loan Documents for execution by the parties thereto, and may not be
used for any other purpose.

            (d) Reliance by Agent and Banks. The Agent and the Banks shall be
entitled to rely and act upon any notices purportedly given by or on behalf of
the Company even if (i) such notices were not made in a manner specified herein,
were incomplete or were not preceded or followed by any other form of notice
specified herein, or (ii) the terms thereof, as understood by the recipient,
varied from any confirmation thereof. The Company shall indemnify each
Agent-Related Person and each Bank from all losses, costs, expenses and
liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of the Company; provided that such indemnity
shall not be available to the extent that such losses, costs, expenses and
liabilities resulted solely from the gross negligence or willful misconduct of
such Person.


                                       58

All telephonic notices to and other communications with the Agent pursuant to
Section 2 may be recorded by the Agent, and each of the parties hereto hereby
consents to such recording.

      10.03 No Waiver; Cumulative Remedies. No failure by any Bank or the Agent
to exercise, and no delay by any such Person in exercising, any right, remedy,
power or privilege hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges
herein provided are cumulative and not exclusive of any rights, remedies, powers
and privileges provided by law.

      10.04 Attorney Costs, Expenses and Taxes. The Company agrees (a) within 30
calendar days after demand, to pay or reimburse the Agent for all reasonable
costs and expenses incurred in connection with the development, preparation,
negotiation, execution and syndication of this Agreement and the other Loan
Documents and any amendment, waiver, consent or other modification of the
provisions hereof and thereof (whether or not the transactions contemplated
hereby or thereby are consummated), and the consummation and administration of
the transactions contemplated hereby and thereby, including all reasonable
Attorney Costs; and (b) within five Business Days after demand, to pay or
reimburse the Agent and each Bank for all costs and expenses incurred in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or the other Loan Documents (including
all such costs and expenses incurred during any "workout" or restructuring in
respect of the Obligations and during any legal proceeding, including any
Insolvency Proceeding), including all Attorney Costs. The foregoing costs and
expenses shall include all search, filing, recording, title insurance and
appraisal charges and fees and taxes related thereto, and other out-of-pocket
expenses incurred by the Agent and the cost of independent public accountants
and other outside experts retained by the Agent or any Bank. The agreements in
this Section shall survive the termination of the Commitments and repayment of
all other Obligations.

      10.05 Indemnification by the Company. Whether or not the transactions
contemplated hereby are consummated, the Company shall indemnify and hold
harmless each Agent-Related Person, each Bank and their respective Affiliates,
directors, officers, employees, counsel, agents and attorneys-in-fact
(collectively the "Indemnitees") from and against any and all liabilities,
obligations, losses, damages, penalties, claims, demands, actions, judgments,
suits, costs, expenses and disbursements (including reasonable Attorney Costs)
of any kind or nature whatsoever which may at any time be imposed on, incurred
by or asserted against any such Indemnitee in any way relating to or arising out
of or in connection with (a) the execution, delivery, enforcement, performance
or administration of any Loan Document or any other agreement, letter or
instrument delivered in connection with the transactions contemplated thereby or
the consummation of the transactions contemplated thereby; (b) any Commitment or
Loan or the use or proposed use of the proceeds therefrom; (c) any actual or
alleged presence or release of Hazardous Materials on or from any property
currently or formerly owned or operated by the Company, or any Environmental
Claims related in any way to the Company; or (d) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory (including any investigation
of, preparation for, or defense of any pending or threatened claim,
investigation, litigation or proceeding) and regardless of whether any
Indemnitee is a party thereto (all the foregoing,


                                       59

collectively, the "Indemnified Liabilities"), in all cases, whether or not
caused by or arising, in whole or in part, out of the negligence of the
Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulted
solely from the gross negligence or willful misconduct of such Indemnitee. The
agreements in this Section shall survive the resignation of the Agent, the
replacement of any Bank, the termination of the Commitments and the repayment,
satisfaction or discharge of all the other Obligations. All amounts due under
this Section 10.05 shall be payable within ten Business Days after demand
therefor.

      10.06 Payments Set Aside. To the extent that the Company makes a payment
to the Agent or any Bank, or the Agent or any Bank exercises its right of
set-off, and such payment or the proceeds of such set-off or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required (including pursuant to any settlement entered into by the Agent or
such Bank in its discretion) to be repaid to a trustee, receiver or any other
party, in connection with any Insolvency Proceeding or otherwise, then (a) to
the extent of such recovery, the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such set-off had not occurred; and (b) each
Bank severally agrees to pay to the Agent upon demand its applicable share of
any amount so recovered from or repaid by the Agent, plus interest thereon from
the date of such demand to the date such payment is made at a rate per annum
equal to the Federal Funds Rate from time to time in effect.

      10.07 Successors and Assigns.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Company may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Bank (and any attempted assignment or transfer by the Company without such
consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby, Participants
to the extent provided in subsection (d) of this Section and, to the extent
expressly contemplated hereby, the Indemnitees) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

            (b) Any Bank may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans (including for
purposes of this subsection (b), at the time owing to it); provided that (i) so
long as no Event of Default has occurred and is continuing, the Company consents
thereto (each such consent not to be unreasonably withheld or delayed), (ii)
except in the case of an assignment of the entire remaining amount of the
assigning Bank's Commitment and the Loans at the time owing to it or in the case
of an assignment to a Bank or an Affiliate of a Bank or an Approved Fund with
respect to a Bank, the aggregate amount of the Commitment (which for this
purpose includes Loans outstanding thereunder) subject to each such assignment,
determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Agent or, if "Trade Date" is specified in the
Assignment and Assumption, as of the Trade Date, shall not be less than
$5,000,000 unless each of the Agent and, so long as no



                                       60

Event of Default has occurred and is continuing, the Company otherwise consents
(each such consent not to be unreasonably withheld or delayed), (iii) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Bank's rights and obligations under this Agreement with respect to
the Loans or the Commitment assigned, and (iv) the parties to each assignment
shall execute and deliver to the Agent an Assignment and Assumption in the form
of Exhibit E ("Assignment and Assumption"), together with a processing and
recordation fee of $3,500. Subject to acceptance and recording thereof by the
Agent pursuant to subsection (c) of this Section, from and after the effective
date specified in each Assignment and Assumption, the Eligible Assignee
thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a
Bank under this Agreement, and the assigning Bank thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Bank's rights and obligations under
this Agreement, such Bank shall cease to be a party hereto but shall continue to
be entitled to the benefits of Sections 3.01, 3.03, 3.04 and 10.5 with respect
to facts and circumstances occurring prior to the effective date of such
assignment). Upon request, the Company (at its expense) shall execute and
deliver new or replacement Notes to the assigning Bank and the assignee Bank;
provided, that the assigning Bank shall have delivered to the Company either
each original Note to be replaced, marked "canceled", or its executed standard
form of lost note indemnity. Any assignment or transfer by a Bank of rights or
obligations under this Agreement that does not comply with this subsection shall
be treated for purposes of this Agreement as a sale by such Bank of a
participation in such rights and obligations in accordance with subsection (d)
of this Section.

            (c) The Agent, acting solely for this purpose as an agent of the
Company, shall maintain at the Agent's Payment Office a copy of each Assignment
and Assumption delivered to it and a register for the recordation of the names
and addresses of the Banks, and the Commitments of, and principal amounts of the
Loans owing to, each Bank pursuant to the terms hereof from time to time (the
"Register"). The entries in the Register shall be conclusive, and the Company,
the Agent and the Banks may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Bank hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Company and any Bank, at any reasonable time and
from time to time upon reasonable prior notice.

            (d) Any Bank may at any time, without the consent of, or notice to,
the Company or the Agent, sell participations to any Person (other than a
natural person or the Company or any of the Company's Affiliates or Subsidiaries
(each, a "Participant") in all or a portion of such Bank's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans owing to it); provided that (i) such Bank's obligations under
this Agreement shall remain unchanged, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations,
and (iii) the Company, the Agent and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Bank sells such a participation shall provide that such Bank shall retain the
sole right to enforce this Agreement and to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such agreement or
instrument may provide that such Bank will


                                       61

not, without the consent of the Participant, agree to any amendment, waiver or
other modification that would (i) postpone any date upon which any payment of
money is scheduled to be paid to such Participant, or (ii) reduce the principal,
interest, fees or other amounts payable to such Participant. Subject to
subsection (e) of this Section, the Company agrees that each Participant shall
be entitled to the benefits of Sections 3.01, 3.03 and 3.04 to the same extent
as if it were a Bank and had acquired its interest by assignment pursuant to
subsection (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 10.09 as though it were a
Bank, provided such Participant agrees to be subject to Section 2.13 as though
it were a Bank.

            (e) A Participant shall not be entitled to receive any greater
payment under Section 3.01 or 3.03 than the applicable Bank would have been
entitled to receive with respect to the participation sold to such Participant
(determined as if the Bank had not sold such participation), unless the sale of
the participation to such Participant is made with the Company's prior written
consent. A Participant that would be a Foreign Bank if it were a Bank shall not
be entitled to the benefits of Section 3.01 unless the Company is notified of
the participation sold to such Participant and such Participant agrees, for the
benefit of the Company, to comply with Section 10.16 as though it were a Bank.

            (f) Any Bank may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including under its
Notes, if any) to secure obligations of such Bank, including any pledge or
assignment to secure obligations to a Federal Reserve Bank; provided that no
such pledge or assignment shall release such Bank from any of its obligations
hereunder or substitute any such pledgee or assignee for such Bank as a party
hereto.

      10.08 Confidentiality. Each of the Agent and the Banks agrees to maintain
the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its and its Affiliates' directors, officers,
employees and agents, including accountants, legal counsel and other advisors
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential); (b) to the extent requested by any regulatory
authority; (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process; (d) to any other party to this Agreement;
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder; (f) subject to an agreement containing provisions substantially the
same as those of this Section, to (i) any Eligible Assignee of or Participant
in, or any prospective Eligible Assignee of or Participant in, any of its rights
or obligations under this Agreement or (ii) any direct or indirect contractual
counterparty or prospective counterparty (or such contractual counterparty's or
prospective counterparty's professional advisor) to any credit derivative
transaction relating to obligations of the Company; (g) with the consent of the
Company; (h) to the extent such Information (i) becomes publicly available other
than as a result of a breach of this Section or (ii) becomes available to the
Agent or any Bank on a nonconfidential basis from a source other than the
Company; or (i) to the National Association of Insurance Commissioners or any
other similar organization or any nationally recognized rating agency that
requires access to information about a Bank's or its Affiliates' investment
portfolio in connection with ratings issued with respect to such Bank or its
Affiliates. For the purposes of this Section, "Information" means all
information received from the Company relating to the Company or its business,
other


                                       62

than any such information that is available to the Agent or any Bank on a
nonconfidential basis prior to disclosure by the Company; provided that, in the
case of information received from the Company after the date hereof, such
information is clearly identified in writing at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information.

      10.09 Set-off. In addition to any rights and remedies of the Banks
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company (on its
own behalf and on behalf of its Subsidiaries) to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held by, and other indebtedness at any
time owing by, such Bank to or for the credit or the account of the respective
Loan Parties against any and all Obligations owing to such Bank, now or
hereafter existing, irrespective of whether or not the Agent or such Bank shall
have made demand under this Agreement or any other Loan Document and although
such Obligations may be contingent or unmatured. Each Bank agrees promptly to
notify the Company and the Agent after any such set-off and application made by
such Bank; provided, however, that the failure to give such notice shall not
affect the validity of such set-off and application.

      10.10 Automatic Debits of Fees. With respect to any commitment fee,
utilization fee, arrangement fee, or other fee, or any other cost or expense
(including Attorney Costs) due and payable to the Agent or the Arranger under
the Loan Documents, the Company hereby irrevocably authorizes the Agent to debit
any deposit account of the Company with the Agent in an amount such that the
aggregate amount debited from all such deposit accounts does not exceed such fee
or other cost or expense. If there are insufficient funds in such deposit
accounts to cover the amount of the fee or other cost or expense then due, such
debits will be reversed (in whole or in part, in the Agent's sole discretion)
and such amount not debited shall be deemed to be unpaid. No such debit under
this Section shall be deemed a set-off.

      10.11 Interest Rate Limitation. Notwithstanding anything to the contrary
contained in any Loan Document, the interest paid or agreed to be paid under the
Loan Documents shall not exceed the maximum rate of non-usurious interest
permitted by applicable law (the "Maximum Rate"). If the Agent or any Bank shall
receive interest in an amount that exceeds the Maximum Rate, the excess interest
shall be applied to the principal of the Loans or, if it exceeds such unpaid
principal, refunded to the Company. In determining whether the interest
contracted for, charged, or received by the Agent or a Bank exceeds the Maximum
Rate, such Person may, to the extent permitted by applicable law, (a)
characterize any payment that is not principal as an expense, fee, or premium
rather than interest; (b) exclude voluntary prepayments and the effects thereof;
and (c) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the contemplated term of the Obligations.

      10.12 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.



                                       63

      10.13 Integration. This Agreement, together with the other Loan Documents,
comprises the complete and integrated agreement of the parties on the subject
matter hereof and thereof and supersedes all prior agreements, written or oral,
on such subject matter. In the event of any conflict between the provisions of
this Agreement and those of any other Loan Document, the provisions of this
Agreement shall control; provided that the inclusion of supplemental rights or
remedies in favor of the Agent or the Banks in any other Loan Document shall not
be deemed a conflict with this Agreement. Each Loan Document was drafted with
the joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

      10.14 Survival of Representations and Warranties. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the Agent and
each Bank, regardless of any investigation made by the Agent or any Bank or on
their behalf and notwithstanding that the Agent or any Bank may have had notice
or knowledge of any Default or Event of Default at the time of the Borrowers,
and shall continue in full force and effect as long as any Loan or any other
Obligation shall remain unpaid or unsatisfied.

      10.15 Severability. Any provision of this Agreement and the other Loan
Documents to which the Company is a party that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions thereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      10.16 Tax Forms. Each Bank that is not a "United States person" within the
meaning of Section 7701(a)(30) of the Code (a "Foreign Bank") shall deliver to
the Agent, prior to receipt of any payment subject to withholding under the Code
(or upon accepting an assignment of an interest herein), two duly signed
completed copies of either IRS Form W-8BEN or any successor thereto (relating to
such Person and entitling it to an exemption from, or reduction of, withholding
tax on all payments to be made to such Person by the Company pursuant to this
Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments
to be made to such Person by the Company pursuant to this Agreement) or such
other evidence satisfactory to the Company and the Agent that such Person is
entitled to an exemption from, or reduction of, U.S. withholding tax. Thereafter
and from time to time, each such Person shall (i) promptly submit to the Agent
such additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Company and the Agent of any available exemption from or reduction of, United
States withholding taxes in respect of all payments to be made to such Person by
the Company pursuant to this Agreement, (ii) promptly notify the Administrative
Agent of any change in circumstances which would modify or render invalid any
claimed exemption or reduction, and (iii) take such steps as shall not be
materially disadvantageous to it, in the reasonable judgment of such Bank, and
as may be reasonably necessary (including the re-designation of its Lending
Office) to avoid any requirement of applicable Laws that the Company make any
deduction or withholding for taxes from amounts


                                       64

payable to such Person. If such Person fails to deliver the above forms or other
documentation, then the Agent may withhold from any interest payment to such
Person an amount equivalent to the applicable withholding tax imposed by
Sections 1441 and 1442 of the Code, without reduction.

            (a) Upon the request of the Agent, each Bank that is a "United
States person" within the meaning of Section 7701(a)(30) of the Code shall
deliver to the Agent two duly signed completed copies of IRS Form W-9. If such
Bank fails to deliver such forms, then the Agent may withhold from any interest
payment to such Bank an amount equivalent to the applicable back-up withholding
tax imposed by the Code, without reduction.

            (b) If any Governmental Authority asserts that the Agent did not
properly withhold or backup withhold, as the case may be, any tax or other
amount from payments made to or for the account of any Bank, such Bank shall
indemnify the Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to the Administrative Agent
under this Section, and costs and expenses (including Attorney Costs) of the
Agent. The obligation of the Banks under this Section shall survive the
termination of the Commitments, repayment of all Obligations and the resignation
of the Agent.

      10.17 Governing Law.

            (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF CALIFORNIA APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE AGENT AND EACH BANK
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

            (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA
OR OREGON OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF CALIFORNIA OR
OREGON, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE COMPANY, THE Agent
AND EACH BANK CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE COMPANY, THE Agent AND EACH BANK
IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT
OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. THE COMPANY, THE Agent
AND EACH BANK WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER
PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH
STATE.

      10.18 Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT
HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION
OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE


                                       65

DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT,
OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR
HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND
EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY
PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

                            [Signature pages follow.]












                                       66

            IN WITNESS WHEREOF, the parties hereto have caused this Bridge Loan
Agreement to be duly executed and delivered in San Francisco, California, by

written.
