                             PRA INTERNATIONAL, INC.
                   AMENDED AND RESTATED 1993 STOCK OPTION PLAN

         1.       Purpose of the Plan. Under this Amended and Restated 1993
Stock Option Plan (the "Plan") of PRA International, Inc. (the "Company")
options may be granted to eligible employees to purchase shares of the Company's
capital stock. The Plan is designed to enable the Company and its subsidiaries
to attract, retain and motivate their employees by providing for or increasing
the proprietary interests of such employees in the Company. The Plan provides
for options which qualify as incentive stock options ("Incentive Options") under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), as
well as options which do not so qualify.

         2.       Stock Subject to Plan. The maximum number of shares of stock
for which options granted hereunder may be exercised shall be 1,500,000 shares
of Common Stock, subject to the adjustments provided in Sections 6 and 11;
provided, however, that in no event shall any optionee be granted in any
calendar year options to purchase more than 500,000 shares. Shares of stock
subject to the unexercised portions of any options granted under this Plan which
expire or terminate or are cancelled may again be subject to options under the
Plan. However, if stock appreciation rights are granted with respect to any
options under this Plan, the total number of shares of stock for which further
options may be granted under this Plan shall be irrevocably reduced not only
when there is an exercise of an option granted under this Plan, but also when
such option is surrendered upon an exercise of a stock appreciation right
granted under this Plan, in either case by the number of shares covered by the
portion of such option which is exercised or surrendered.

         3.       Eligible Employees. The employees eligible to be considered
for the grant of options hereunder are all persons regularly employed by the
Company or its subsidiaries on a full-time basis.

         4.       Minimum Exercise Price. The exercise price for each option
granted hereunder shall be not less than 100% of the fair market value of the
stock at the date of the grant of the option.

         5.       Nontransferability. Any option granted under this Plan shall
by its terms be nontransferable by the optionee other than by will or the laws
of descent and distribution and is exercisable during the optionee's lifetime
only by him or by his guardian or legal representative.

         6.       Adjustments. If the outstanding shares of stock of the class
then subject to this Plan are increased or decreased, or are changed into or
exchanged for a different number or kind of shares or securities, as a result of
one or more reorganizations, recapitalizations, stock splits, reverse stock
splits, stock dividends (including, without limitation, the stock dividend
contemplated in connection with the Company's proposed initial public offering)
or the like, appropriate adjustments shall be made in the number and/or kind of
shares or securities for which options may thereafter be granted under this
Plan. Like adjustments shall also be made in the number and/or kind of shares or
securities for which, and the exercise price per share at which, options then
outstanding under this Plan may thereafter be exercised. Any such adjustment in
outstanding options shall be made without changing the aggregate exercise price
applicable to the unexercised portions of such options.

         7.       Maximum Option Term. No option granted under this Plan may be
exercised in whole or in part more than ten years after its date of grant. In
the case of an option not otherwise immediately exercisable in full, the Board
or the Committee may accelerate the exercisability of such option in whole or in
part at any time, provided the acceleration of the exercisability of any
Incentive Option would not cause the option to fail to comply with the
provisions of Section 422 of the Code.

         8.       Plan Duration. Options may not be granted under this Plan more
than ten years after the date of the adoption of this Plan, or of shareholder
approval thereof, whichever is earlier.

         9.       Payment. Payment for stock purchased upon any exercise of an
option granted under this Plan shall be made in full in cash concurrently with
such exercise.

         10.      Administration. The Plan shall be administered by the
Company's board of directors (the "Board") or, at the discretion of the Board,
by a committee (the "Committee") of not less than two members each of whom shall
not be an officer or employee of the Company.

         The interpretation and construction by the Committee of any term or
provision of the Plan or of any option granted under it shall be final, unless
otherwise determined by the Board in which event such determination by the Board
shall be final. The Committee may from time to time adopt rules and regulations
for carrying out this Plan and, subject to the provisions of this Plan, may
prescribe the form or forms of the instruments evidencing any option granted
under this Plan.

                                       -3-

         Subject to the provisions of this Plan, the Board or, by delegation
from the Board, the Committee, shall have full and final authority in its
discretion to select the employees to be granted options, to grant such options
and to determine the number of shares to be subject thereto, the exercise
prices, the terms of exercise, expiration dates and other pertinent provisions
thereof.

         11. Accelerated Vesting in the Event of a Change in Control. All
outstanding options held by employees shall Accelerate upon the occurrence of a
Change in Control of the Company. Any options Accelerated in connection with a
Change in Control shall remain fully exercisable until the expiration or sooner
termination of the Option period. For purposes of this Section 11, the following
definitions shall be applicable:

                  (a)      Accelerate, Accelerated and Acceleration, when used
         with respect to an option, mean that as of the relevant time of
         reference, such option shall become fully exercisable with respect to
         the total number of shares of stock subject to such option and may be
         exercised for all or any portion of such shares;

                  (b)      Beneficial Ownership means beneficial ownership
         determined pursuant to Securities and Exchange Commission Rule 13d-3
         promulgated under the Securities Exchange Act of 1934, as amended; and

                  (c)      Change in Control means a change in ownership or
         control of the Company effected through either of the following
         transactions:

                           (i)      any person or related group of persons
                  (other than the Company or a person that directly or
                  indirectly controls, is controlled by, or is under common
                  control with the Company) directly or indirectly acquires
                  Beneficial Ownership of securities possessing more than 50% of
                  the total combined voting power of the Company's outstanding
                  securities pursuant to a tender or exchange offer made
                  directly to the Company's stockholders that the Board does not
                  recommend such stockholders to accept, or

                           (ii)     over a period of 36 consecutive months or
                  less, there is a change in the composition of the Board such
                  that a majority of the Board members (rounded up to the next
                  whole number, if a fraction) ceases, by reason of one or more
                  proxy contests for the election of Board members, to be
                  composed of individuals who either (A) have been Board members

<PAGE>

                                       -4-

                  continuously since the beginning of such period, or (B) have
                  been elected or nominated for election as Board members during
                  such period by at least a majority of the Board members
                  described in the preceding clause (A) who were still in office
                  at the time such election or nomination was approved by the
                  Board.

         12.      Corporate Reorganizations. Upon the dissolution or liquidation
of the Company, or upon a reorganization, merger or consolidation of the Company
as a result of which the outstanding securities of the class then subject to
options hereunder are changed into or exchanged for cash or property or
securities not of the Company's issue, or any combination thereof, or upon a
sale of substantially all the property of the Company to, or the acquisition of
stock representing more than eighty percent (80%) of the voting power of the
stock of the Company then outstanding by, another corporation or person, the
Plan shall terminate, and all options theretofore granted hereunder shall
terminate, unless provision be made in writing in connection with such
transaction for the continuance of the Plan and/or for the assumption of options
theretofore granted, or the substitution for such options of options covering
the stock of a successor employer corporation, or a parent or a subsidiary
thereof, with appropriate adjustments as to the number and kind of shares and
prices, in which event the Plan and options theretofore granted shall continue
in the manner and under the terms so provided. If the Plan and unexercised
options shall terminate pursuant to the foregoing sentence, all persons entitled
to exercise any unexercised portions of options then outstanding, including,
without limitation, as the result of any Acceleration of options in accordance
with Section 11 hereof, shall have the right, at such time prior to the
consummation of the transaction causing such termination as the Company shall
designate, to exercise the unexercised portions of their options, including the
portions thereof which would, but for this paragraph entitled "Corporate
Reorganization," not yet be exercisable. The instrument evidencing any option
may also provide for such acceleration of otherwise unexercisable portions of
the option upon other specified events or occurrences, such as involuntary
terminations of the optionee's employment following certain changes in the
control of the Company.

         13.      Stock Appreciation Rights. If the instrument evidencing the
option so provides, an option granted under this Plan (herein sometimes called
the "corresponding option") may include the right (a "Stock Appreciation Right")
to receive an amount equal to some or all of the excess of the fair market value
(determined in a manner specified in the instrument evidencing the corresponding
option) of the shares subject to unexercised portions of the corresponding
option over the aggregate exercise price for such shares under the corresponding
option as of the date the Stock Appreciation

<PAGE>

                                       -5-

Right is exercised. The amount payable upon exercise of a Stock Appreciation
Right may be paid in cash or in shares of the class then subject to the
corresponding option (valued on the basis of their fair market value, determined
as specified with respect to the measurement of the amount payable as
aforesaid), or in a combination of cash and such shares so valued. No Stock
Appreciation Right may be exercised in whole or in part (a) other than in
connection with the contemporaneous surrender without exercise of such
corresponding option, or the portion thereof that corresponds to the portion of
the Stock Appreciation Right being exercised, or (b) except to the extent that
the corresponding option or such portion thereof is exercisable on the date of
exercise of the Stock Appreciation Right by the person exercising the Stock
Appreciation Right, or (c) unless the class of stock then subject to the
corresponding option is not then "publicly traded." For this purpose, a class of
stock is "publicly traded" if it is listed or admitted to unlisted trading
privileges on a national securities exchange or if sales or bid and offer
quotations therefor are reported on the automated quotation system ("NASDAQ")
operated by the National Association of Securities Dealers, Inc. or on any then
operative successor to the NASDAQ system.

         14.      Restricted Stock. Unless waived by the Company, shares of
stock issued on exercise of an option granted under this Plan shall upon
issuance be subject to the following restrictions (and, as used herein,
"restricted stock" means shares issued on exercise of options granted under this
Plan which are still subject to restrictions imposed under this Section 13 that
have not yet expired or terminated):

                  (a)      shares of restricted stock may not be sold or
         otherwise transferred or hypothecated;

                  (b)      if the employment of the holder of shares of
         restricted stock with the Company or a subsidiary is terminated for any
         reason other than his death, normal or early retirement in accordance
         with his employer's established retirement policies or practices, or
         total disability, the Company (or any subsidiary designated by it)
         shall have the option for sixty (60) days after such termination of
         employment to purchase for cash all or any part of his restricted stock
         at the lesser of (i) the price paid therefor by the holder, or (ii) the
         fair market value of the restricted stock on the date of such
         termination of employment (determined in a manner specified in the
         instrument evidencing the option); and

                  (c)      as to the shares of stock affected thereby, any
         additional restrictions that may be imposed on particular shares of'
         restricted stock as specified in the instrument evidencing the option.
         The

<PAGE>

                                       -6-

         Company may cause an appropriate legend to be imprinted on the stock
         certificates evidencing shares so issued.

         The restrictions imposed under this Section 14 shall apply as well to
all shares of other securities issued in respect of restricted stock in
connection with any stock split, reverse stock split, stock dividend,
recapitalization, reclassification, spin-off, split-off, merger, consolidation
or reorganization, but such restrictions shall expire or terminate at such time
or times as shall be specified therefor in the instrument evidencing the option
which provides for the restrictions.

         15.      Financial Assistance. The Company is vested with authority
under this Plan to assist any employee to whom an option is granted hereunder
(including any director or officer of the Company or any of its subsidiaries who
is also an employee) in the payment of the purchase price payable on exercise of
that option, by lending the amount of such purchase price to such employee on
such terms and at such rates of interest and upon such security (or unsecured)
as shall have been authorized by or under authority of the Board.

         16.      No Preemptive or Registration Rights. Shares of stock
purchased upon exercise of an option granted under this Plan shall provide the
holder with no preemptive or registration rights to demand sale to such holder
of additional shares of the Company or the inclusion of any of the shares so
purchased in any registration or other qualification by the Company for sale of
shares or other securities.

         17.      Amendment and Termination. The Board may alter, amend, suspend
or terminate this Plan, provided that no such action shall deprive an optionee,
without his consent, of any option granted to the optionee pursuant to this Plan
or of any of his rights under such option. Except as herein provided, no such
action of the Board, unless taken with the approval of the shareholders of the
Company, may:

                  (a)      increase the maximum number of shares for which
         options granted under this plan may be exercised;

                  (b)      reduce the minimum permissible exercise price;

                  (c)      extend the ten-year duration of this Plan set forth
         herein; or

                  (d)      alter the class of employees eligible to receive
         options under the Plan.

         18.      Effective Date. The Company's 1993 Stock Option Plan was

      and conditions of this Agreement and the other Loan Documents.

            (iii) Revolving Loans. Each Revolving Lender severally, but not
      jointly, agrees, subject to the limitations set forth below with respect
      to the maximum amount of Revolving Loans permitted to be outstanding from
      time to time, to lend to Company from time to time during the period from
      the Closing Date to but excluding the Revolving Loan Commitment
      Termination Date an aggregate amount not exceeding its Pro Rata Share of
      the aggregate amount of the Revolving Loan Commitments to be used for the
      purposes identified in subsection 2.5B. The original amount of each
      Revolving Lender's Revolving Loan Commitment is set forth opposite its
      name on Schedule 2.1 annexed hereto and the aggregate original amount of
      the Revolving Loan Commitments is $25,000,000; provided that the Revolving

      Commitments shall be paid in full no later than that date. Amounts
      borrowed under this subsection 2.1A(iii) may be repaid pursuant to
      subsection 2.4B(i) and reborrowed to but excluding the Revolving Loan
      Commitment Termination Date.

            Anything contained in this Agreement to the contrary
      notwithstanding, the Revolving Loans and the Revolving Loan Commitments
      shall be subject to the limitation that in no event shall the Total
      Utilization of Revolving Loan Commitments at any time exceed the Revolving
      Loan Commitments then in effect.

            (iv) Swing Line Loans.

                  (a) General Provisions. Swing Line Lender hereby agrees,
            subject to the limitations set forth below with respect to the
            maximum amount of Swing Line Loans permitted to be outstanding from

                                       28

<PAGE>

            the Revolving Loan Commitments available to Company from time to
            time during the period from the Closing Date to but excluding the
            Revolving Loan Commitment Termination Date by making Swing Line
            Loans to Company in an aggregate amount not exceeding the amount of
            the Swing Line Loan Commitment to be used for the purposes
            identified in subsection 2.5B, notwithstanding the fact that such
            Swing Line Loans, when aggregated with Swing Line Lender's
            outstanding Revolving Loans and Swing Line Lender's Pro Rata Share
            of the Letter of Credit Usage then in effect, may exceed Swing Line
            Lender's Revolving Loan Commitment; provided, however, that Swing
            Line Lender shall have no obligation to make Swing Line Loans to
            Company following the occurrence and during the continuation of an
            Event of Default. The original amount of the Swing Line Loan
            Commitment is $5,000,000; provided that any reduction of the
            Revolving Loan Commitments made pursuant to subsection 2.4 that
            reduces the aggregate Revolving Loan Commitments to an amount less
            than the then current amount of the Swing Line Loan Commitment shall
            result in an automatic corresponding reduction of the Swing Line
            Loan Commitment to the amount of the Revolving Loan Commitments, as
            so reduced, without any further action on the part of Company,
            Administrative Agent or Swing Line Lender. The Swing Line Loan
            Commitment shall expire on the Revolving Loan Commitment Termination
            Date and all Swing Line Loans and all other amounts owed hereunder
            with respect to the Swing Line Loans shall be paid in full no later
            than that date. Amounts borrowed under this subsection 2.1A(iv) may
            be repaid and reborrowed to but excluding the Revolving Loan
            Commitment Termination Date.

                  Anything contained in this Agreement to the contrary
            notwithstanding, the Swing Line Loans and the Swing Line Loan
            Commitment shall be subject to the limitation that in no event shall
            the Total Utilization of Revolving Loan Commitments at any time
            exceed the Revolving Loan Commitments then in effect.

                  (b) Swing Line Loan Prepayment with Proceeds of Revolving
            Loans. With respect to any Swing Line Loans that have not been
            voluntarily prepaid by Company pursuant to subsection 2.4B(i), Swing
            Line Lender may, at any time in its sole and absolute discretion,
            deliver to Administrative Agent (with a copy to Company), no later
            than 10:00 A.M. (San Francisco time) on the first Business Day in
            advance of a proposed Funding Date, a notice requesting Revolving
            Lenders to make Revolving Loans that are Base Rate Loans on such
            Funding Date in an amount equal to the amount of such Swing Line
            Loans (the "REFUNDED SWING LINE LOANS") outstanding on the date such
            notice is given. Company hereby authorizes the giving of any such
            notice and the making of any such Revolving Loans. Anything
            contained in this Agreement to the contrary notwithstanding, (1) the
            proceeds of such Revolving Loans made by Revolving Lenders other
            than Swing Line Lender shall be immediately delivered by
            Administrative Agent to Swing Line Lender (and not to Company) and
            applied to repay a corresponding portion of the Refunded Swing Line
            Loans and (2) on the day such Revolving Loans are made, Swing Line
            Lender's Pro Rata Share of the Refunded Swing Line Loans shall be
            deemed to be paid with the proceeds of a

                                       29

<PAGE>

            Revolving Loan made by Swing Line Lender, and such portion of the
            Swing Line Loans deemed to be so paid shall no longer be outstanding
            as Swing Line Loans and shall no longer be due under the Swing Line
            Note, if any, of Swing Line Lender but shall instead constitute part
            of Swing Line Lender's outstanding Revolving Loans and shall be due
            under the Revolving Note, if any, of Swing Line Lender. Company
            hereby authorizes Administrative Agent and Swing Line Lender to
            charge Company's accounts with Administrative Agent and Swing Line
            Lender (up to the amount available in each such account) in order to
            immediately pay Swing Line Lender the amount of the Refunded Swing
            Line Loans to the extent the proceeds of such Revolving Loans made
            by Revolving Lenders, including the Revolving Loan deemed to be made
            by Swing Line Lender, are not sufficient to repay in full the
            Refunded Swing Line Loans. If any portion of any such amount paid
            (or deemed to be paid) to Swing Line Lender should be recovered by
            or on behalf of Company from Swing Line Lender in any bankruptcy
            proceeding, in any assignment for the benefit of creditors or
            otherwise, the loss of the amount so recovered shall be ratably
            shared among all Lenders in the manner contemplated by subsection
            10.5.

                  (c) Swing Line Loan Assignments. If for any reason (1)
            Revolving Loans are not made upon the request of Swing Line Lender
            as provided in the immediately preceding paragraph in an amount
            sufficient to repay any amounts owed to Swing Line Lender in respect
            of any outstanding Swing Line Loans or (2) the Revolving Loan
            Commitments are terminated at a time when any Swing Line Loans are
            outstanding, each Revolving Lender shall be deemed to, and hereby
            agrees to, have purchased an assignment of such outstanding Swing
            Line Loans in an amount equal to its Pro Rata Share (calculated, in
            the case of the foregoing clause (2), immediately prior to such
            termination of the Revolving Loan Commitments) of the unpaid amount
            of such Swing Line Loans together with accrued interest thereon.
            Upon one Business Day's notice from Swing Line Lender, each
            Revolving Lender shall deliver to Swing Line Lender an amount equal
            to its respective assignment in same day funds at the Funding and
            Payment Office. In order to further evidence such assignment (and
            without prejudice to the effectiveness of the assignment provisions
            set forth above), each Revolving Lender agrees to enter into an
            Assignment Agreement at the request of Swing Line Lender in form and
            substance reasonably satisfactory to Swing Line Lender. In the event
            any Revolving Lender fails to make available to Swing Line Lender
            the amount of such Revolving Lender's assignment as provided in this
            paragraph, Swing Line Lender shall be entitled to recover such
            amount on demand from such Revolving Lender together with interest
            thereon at the rate customarily used by Swing Line Lender for the
            correction of errors among banks for three Business Days and
            thereafter at the Base Rate. In the event Swing Line Lender receives
            a payment of any amount in which other Revolving Lenders have
            purchased assignments as provided in this paragraph, Swing Line
            Lender shall promptly distribute to each such other Revolving Lender
            its Pro Rata Share of such payment.

            to make Revolving Loans for the purpose of repaying any Refunded

            Revolving Lender's obligation to purchase an assignment of any
            unpaid Swing Line Loans pursuant to the immediately preceding
            paragraph shall be absolute and unconditional and shall not be
            affected by any circumstance, including (1) any set-off,
            counterclaim, recoupment, defense or other right which such
            Revolving Lender may have against Swing Line Lender, Company or any
            other Person for any reason whatsoever; (2) the occurrence or
            continuation of an Event of Default or a Potential Event of Default;
            (3) any adverse change in the business, operations, properties,
            assets, condition (financial or otherwise) or prospects of Company
            or any of its Subsidiaries; (4) any breach of this Agreement or any
            other Loan Document by any party thereto; or (5) any other
            circumstance, happening or event whatsoever, whether or not similar
            to any of the foregoing; provided that such obligations of each
            Revolving Lender are subject to the condition that (x) Swing Line
            Lender believed in good faith that all conditions under Section 4 to
            the making of the applicable Refunded Swing Line Loans or other
            unpaid Swing Line Loans, as the case may be, were satisfied at the
            time such Refunded Swing Line Loans or unpaid Swing Line Loans were
            made or (y) the satisfaction of any such condition not satisfied had
            been waived in accordance with subsection 10.6 prior to or at the
            time such Refunded Swing Line Loans or other unpaid Swing Line Loans
            were made.

            Neither Administrative Agent nor any Lender shall incur any
liability to Company in acting upon any telephonic notice referred to above that
Administrative Agent believes in good faith to have been given by an Officer or
other person authorized to borrow on behalf of Company or for otherwise acting
in good faith under this subsection 2.1B or under subsection 2.2D, and upon
funding of Loans by Lenders, and upon conversion or continuation of the
applicable basis for determining the interest rate with respect to any Loans
pursuant to subsection 2.2D, in each case in accordance with this Agreement,
pursuant to any such telephonic notice Company shall have effected Loans or a
conversion or continuation, as the case may be, hereunder.

            Company shall notify Administrative Agent prior to the funding of
any Loans in the event that any of the matters to which Company is required to
certify in the applicable Notice of Borrowing is no longer true and correct as
of the applicable Funding Date, and the acceptance by Company of the proceeds of
any Loans shall constitute a re-certification by Company, as of the applicable
Funding Date, as to the matters to which Company is required to certify in the
applicable Notice of Borrowing.

            Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a
Notice of Borrowing for, or a Notice of Conversion/Continuation for conversion
to, or continuation of, a Eurodollar Rate Loan (or telephonic notice in lieu
thereof) shall be irrevocable on and after the related Interest Rate
Determination Date, and Company shall be bound to make a borrowing or to effect
a conversion or continuation in accordance therewith.

            C. DISBURSEMENT OF FUNDS. All Term Loans and Revolving Loans under
this Agreement shall be made by Lenders simultaneously and proportionately to
their respective Pro Rata Shares, it being understood that neither
Administrative Agent nor any Lender shall be responsible for any default by any
other Lender in that other Lender's obligation to make a Loan requested
hereunder nor shall the Commitment of any Lender to make the particular type of
Loan requested be increased or decreased as a result of a default by any other
Lender in that other Lender's obligation to make a Loan requested hereunder.
Promptly after receipt by Administrative Agent of a Notice of Borrowing pursuant
to subsection 2.1B (or telephonic notice in lieu thereof), Administrative Agent
shall notify each Lender for that type of Loan or Swing Line Lender, as the case
may be, of the proposed borrowing. Each such Lender shall make the amount of its
Loan available to Administrative Agent not later than 11:00 A.M. (San Francisco
time) on the applicable Funding Date, and Swing Line Lender shall make the
amount of its Swing Line Loan available to Administrative Agent not later than
2:00 P.M. (San Francisco time) on the applicable Funding Date, in each case in
same day funds in Dollars, at the Funding and Payment Office. Except as provided
in subsection 2.1A(iv) or subsection 3.3B with respect to Revolving Loans used
to repay Refunded Swing Line Loans or to reimburse any Issuing Lender for the
amount of a drawing under a Letter of Credit issued by it, upon satisfaction or
waiver of the conditions precedent specified in subsections 4.1 (in the case of
Loans made on the Closing Date) and 4.2 (in the case of all Loans),
Administrative Agent shall make the proceeds of such Loans available to Company
on the applicable Funding Date by causing an amount of same day funds in Dollars
equal to the proceeds of all such Loans received by Administrative Agent from
Lenders to be credited to the account of Company at the Funding and Payment
Office.

                                       32

<PAGE>

            Unless Administrative Agent shall have been notified by any Lender
prior to a Funding Date for any Loans that such Lender does not intend to make
available to Administrative Agent the amount of such Lender's Loan requested on
such Funding Date, Administrative Agent may assume that such Lender has made
such amount available to Administrative Agent on such Funding Date and
Administrative Agent may, in its sole discretion, but shall not be obligated to,
make available to Company a corresponding amount on such Funding Date. If such
corresponding amount is not in fact made available to Administrative Agent by
such Lender, Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender together with interest thereon,
for each day from such Funding Date until the date such amount is paid to
Administrative Agent, at the customary rate set by Administrative Agent for the
correction of errors among banks for three Business Days and thereafter at the
Base Rate. If such Lender does not pay such corresponding amount forthwith upon
Administrative Agent's demand therefor, Administrative Agent shall promptly
notify Company and Company shall immediately pay such corresponding amount to
Administrative Agent together with interest thereon, for each day from such
Funding Date until the date such amount is paid to Administrative Agent, at the
rate payable under this Agreement for Base Rate Loans. Nothing in this
subsection 2.1C shall be deemed to relieve any Lender from its obligation to
fulfill its Commitments hereunder or to prejudice any rights that Company may
have against any Lender as a result of any default by such Lender hereunder.

            D. THE REGISTER. Administrative Agent, acting for these purposes
solely as an agent of Company (it being acknowledged that Administrative Agent,
in such capacity, and its officers, directors, employees, agent and affiliates
shall constitute Indemnitees under subsection 10.3), shall maintain (and make
available for inspection by Company and Lenders upon reasonable prior notice at
reasonable times) at its address referred to in subsection 10.8 a register for
the recordation of, and shall record, the names and addresses of Lenders and the
Tranche A Term Loan Commitment, Tranche B Term Loan Commitment, Revolving Loan
Commitment, Swing Line Loan Commitment, Tranche A Term Loan, Tranche B Term
Loan, Revolving Loans and Swing Line Loans of each Lender from time to time (the
"REGISTER"). Company, Administrative Agent and Lenders shall deem and treat the
Persons listed as Lenders in the Register as the holders and owners of the
corresponding Commitments and Loans listed therein for all purposes hereof; all
amounts owed with respect to any Commitment or Loan shall be owed to the Lender
listed in the Register as the owner thereof; and any request, authority or
consent of any Person who, at the time of making such request or giving such
authority or consent, is listed in the Register as a Lender shall be conclusive
and binding on any subsequent holder, assignee or transferee of the
corresponding Commitments or Loans. Each Lender shall record on its internal
records the amount of its Loans and Commitments and each payment in respect
hereof, and any such recordation shall be conclusive and binding on Company,
absent manifest error, subject to the entries in the Register, which shall,
absent manifest error, govern in the event of any inconsistency with any
Lender's records. Failure to make any recordation in the Register or in any
Lender's records, or any error in such recordation, shall not affect any Loans
or Commitments or any Obligations in respect of any Loans.

            E. OPTIONAL NOTES. If so requested by any Lender by written notice
to Company (with a copy to Administrative Agent) at least two Business Days
prior to the Closing Date or at any time thereafter, Company shall execute and
deliver to such Lender (and/or, if applicable and if so specified in such
notice, to any Person who is an assignee of such Lender

                                       33

pursuant to subsection 10.1) on the Closing Date (or, if such notice is
delivered after the Closing Date, promptly after Company's receipt of such
notice) a promissory note or promissory notes to evidence such Lender's Tranche
A Term Loan, Tranche B Term Loan, Revolving Loans or Swing Line Loans,
substantially in the form of Exhibit IV, Exhibit V, Exhibit VI or Exhibit VII
annexed hereto, respectively, with appropriate insertions.

      2.2   INTEREST ON THE LOANS.

            A. RATE OF INTEREST. Subject to the provisions of subsections 2.6
and 2.7, each Term Loan and each Revolving Loan shall bear interest on the
unpaid principal amount thereof from the date made through maturity (whether by
acceleration or otherwise) at a rate determined by reference to the Base Rate or
the Eurodollar Rate. Subject to the provisions of subsection 2.7, each Swing
Line Loan shall bear interest on the unpaid principal amount thereof from the
date made through maturity (whether by acceleration or otherwise) at a rate
determined by reference to the Base Rate. The applicable basis for determining
the rate of interest with respect to any Term Loan or any Revolving Loan shall
be selected by Company initially at the time a Notice of Borrowing is given with
respect to such Loan pursuant to subsection 2.1B, and the basis for determining
the interest rate with respect to any Term Loan or any Revolving Loan may be
changed from time to time pursuant to subsection 2.2D. If on any day a Term Loan
or Revolving Loan is outstanding with respect to which notice has not been
delivered to Administrative Agent in accordance with the terms of this Agreement
specifying the applicable basis for determining the rate of interest, then for
that day that Loan shall bear interest determined by reference to the Base Rate.

            (i) Subject to the provisions of subsections 2.2E, 2.2G and 2.7, the
      Tranche A Term Loans and the Revolving Loans shall bear interest through
      maturity as follows:

                  (a) if a Base Rate Loan, then at the sum of the Base Rate plus
            the Base Rate Margin set forth in the table below opposite the
            Consolidated Leverage Ratio for the four Fiscal Quarter period for
            which the applicable Compliance Certificate has been delivered

                  (b) if a Eurodollar Rate Loan, then at the sum of the
            Eurodollar Rate plus the Eurodollar Rate Margin set forth in the
            table below opposite the Consolidated Leverage Ratio for the four
            Fiscal Quarter period for which the applicable Compliance
            Certificate has been delivered pursuant to subsection 6.1(v):

            (ii) in the case of immediately successive Interest Periods
      applicable to a Eurodollar Rate Loan continued as such pursuant to a
      Notice of Conversion/Continuation, each successive Interest Period shall
      commence on the day on which the next preceding Interest Period expires;

            (iii) if an Interest Period would otherwise expire on a day that is
      not a Business Day, such Interest Period shall expire on the next
      succeeding Business Day; provided that, if any Interest Period would
      otherwise expire on a day that is not a Business Day but is a day of the
      month after which no further Business Day occurs in such month, such
      Interest Period shall expire on the next preceding Business Day;

            (iv) any Interest Period that begins on the last Business Day of a
      calendar month (or on a day for which there is no numerically
      corresponding day in the calendar month at the end of such Interest
      Period) shall, subject to clause (v) of this subsection 2.2B, end on the
      last Business Day of a calendar month;

      the Revolving Loans shall extend beyond the Revolving Loan Commitment
      Termination Date;

            (vi) no Interest Period with respect to any type of Term Loans shall
      extend beyond a date on which Company is required to make a scheduled
      payment of principal of such type of Term Loans, unless the sum of (a) the
      aggregate principal amount of such type of Term Loans that are Base Rate
      Loans plus (b) the aggregate principal amount of such type of Term Loans
      that are Eurodollar Rate Loans with Interest Periods expiring on or before
      such date equals or exceeds the principal amount required to be paid on
      such type of Term Loans on such date;

            (vii) there shall be no more than ten Interest Periods outstanding
      at any time; and

            (viii) in the event Company fails to specify an Interest Period for

      of Conversion/Continuation, Company shall be deemed to have selected an
      Interest Period of one month.

            C. INTEREST PAYMENTS. Subject to the provisions of subsection 2.2E,
interest on each Loan shall be payable in arrears on and to each Interest
Payment Date applicable to that Loan, upon any prepayment of that Loan (to the
extent accrued on the amount being prepaid) and at maturity (including final
maturity); provided that in the event any Swing Line Loans or any Revolving
Loans that are ase Rate Loans are prepaid pursuant to subsection 2.4B(i),
interest accrued on such Loans through the date of such prepayment shall be
payable on the next succeeding Interest Payment Date applicable to Base Rate
Loans (or, if earlier, at final maturity).

            D. CONVERSION OR CONTINUATION. Subject to the provisions of
subsection 2.6, Company shall have the option (i) to convert at any time all or
any part of its outstanding Tranche A Term Loans, Tranche B Term Loans or
Revolving Loans equal to $500,000 and multiples of $100,000 in excess of that
amount from Loans bearing interest at a rate determined by reference to one
basis to Loans bearing interest at a rate determined by reference to an
alternative basis or (ii) upon the expiration of any Interest Period applicable
to a Eurodollar Rate Loan, to continue all or any portion of such Loan equal to
$500,000 and multiples of $100,000 in excess of that amount as a Eurodollar Rate
Loan; provided, however, that a Eurodollar Rate Loan may only be converted into
a Base Rate Loan on the expiration date of an Interest Period applicable
thereto.

            Company shall deliver a duly executed Notice of
Conversion/Continuation to Administrative Agent no later than 10:00 A.M. (San
Francisco time) at least one Business Day in advance of the proposed conversion
date (in the case of a conversion to a Base Rate Loan) and at least three
Business Days in advance of the proposed conversion/continuation date (in the
case of a conversion to, or a continuation of, a Eurodollar Rate Loan). In lieu
of delivering a Notice of Conversion/Continuation, Company may give
Administrative Agent telephonic notice by the required time of any proposed
conversion/continuation under this subsection 2.2D; provided that such notice
shall be promptly confirmed in writing by delivery of a duly executed Notice of
Conversion/Continuation to Administrative Agent on or before the proposed
conversion/continuation date. Upon receipt of written or telephonic notice of
any proposed conversion/continuation under this subsection 2.2D, Administrative
Agent shall promptly transmit such notice by telefacsimile or telephone to each
Lender of the Loan subject to the Notice of Conversion/Continuation.

            E. DEFAULT RATE. Upon the occurrence and during the continuation of
any Event of Default, the outstanding principal amount of all Loans and, to the
extent permitted by applicable law, any interest payments thereon not paid when
due and any fees and other amounts then due and payable hereunder, shall
thereafter bear interest (including post-petition interest in any proceeding
under the Bankruptcy Code or other applicable bankruptcy laws) payable upon
demand at a rate that is 2% per annum in excess of the interest rate otherwise
payable under this Agreement with respect to the applicable Loans (or, in the
case of any such fees and other amounts, at a rate which is 2% per annum in
excess of the interest rate otherwise payable under this Agreement for Base Rate
Loans); provided that, in the case of Eurodollar Rate Loans, upon the expiration
of the Interest Period in effect at the time any such increase in interest rate
is effective such Eurodollar Rate Loans shall thereupon become Base Rate Loans
and shall thereafter bear interest payable upon demand at a rate which is 2% per
annum in excess of the interest rate otherwise payable under this Agreement for
Base Rate Loans. Payment or acceptance of the increased rates of interest
provided for in this subsection 2.2E is not a permitted alternative to timely
payment and shall not constitute a waiver of any Event of Default or otherwise
prejudice or limit any rights or remedies of Administrative Agent or any Lender.

            F. COMPUTATION OF INTEREST. Interest on the Loans shall be computed
(i) in the case of Base Rate Loans, on the basis of a 365-day or 366-day year,
as the case may be, and (ii) in the case of Eurodollar Rate Loans, on the basis
of a 360-day year, in each case for the actual number of days elapsed in the
period during which it accrues. In computing interest on any Loan, the date of
the making of such Loan or the first day of an Interest Period applicable to

                                       38

such Loan or, with respect to a Base Rate Loan being converted from a Eurodollar
Rate Loan, the date of conversion of such Eurodollar Rate Loan to such Base Rate
Loan, as the case may be, shall be included, and the date of payment of such
Loan or the expiration date of an Interest Period applicable to such Loan or,
with respect to a Base Rate Loan being converted to a Eurodollar Rate Loan, the
date of conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the
case may be, shall be excluded; provided that if a Loan is repaid on the same
day on which it is made, one day's interest shall be paid on that Loan.

            G. MAXIMUM RATE. Notwithstanding the foregoing provisions of this
subsection 2.2, in no event shall the rate of interest payable by Company with
respect to any Loan exceed the maximum rate of interest permitted to be charged
under applicable law.

            permanently reduced in an aggregate amount equal to 50% of such
            Consolidated Excess Cash Flow, provided that such percentage shall
            be reduced to 0% of Consolidated Excess Cash Flow in respect of any
            Fiscal Year for which the Consolidated Leverage Ratio (determined as
            of the last day of such Fiscal Year) is less than or equal to 2.0 to
            1.0.

                  (f) Calculations of Net Proceeds Amounts; Additional
            Prepayments and Reductions Based on Subsequent Calculations.
            Concurrently with any prepayment of the Loans and/or reduction of
            the Revolving Loan Commitments pursuant to subsections
            2.4B(iii)(a)-(e), Company shall deliver to Administrative Agent an
            Officer's Certificate demonstrating the calculation of the amount of
            the applicable Net Asset Sale Proceeds, Net Insurance/Condemnation
            Proceeds, Net Securities Proceeds, or Consolidated Excess Cash Flow,
            as the case may be, that gave rise to such prepayment and/or
            reduction. In the event that Company shall subsequently determine
            that the actual amount was greater than the amount set forth in such
            Officer's Certificate, Company shall promptly make an additional
            prepayment of the Loans (and/or, if applicable, the Revolving Loan
            Commitments shall be permanently reduced) in an amount equal to the
            amount of such excess, and Company shall concurrently therewith
            deliver to Administrative Agent an Officer's Certificate
            demonstrating the derivation of the additional amount resulting in
            such excess.

                  (g) Prepayments Due to Reductions or Restrictions of Revolving
            Loan Commitments. Company shall from time to time prepay first the
            Swing Line Loans and second the Revolving Loans to the extent
            necessary so that the Total Utilization of Revolving Loan
            Commitments shall not at any time exceed the Revolving Loan
            Commitments then in effect.

                  (h) Prepayments and Reductions from Term Loan Proceeds Not
            Used Pursuant to Subsection 2.5A. No later than March 16, 2004,
            Company shall prepay the Loans and/or the Revolving Loan Commitments
            shall be permanently reduced in an aggregate amount equal to any
            portion of the amount of proceeds described in clause (ii) of
            subsection 2.5A that has not been used for the purposes specified in
            such clause by March 15, 2004 (excluding the amount of proceeds
            retained pending vesting of employee stock options).

            (iv) Application of Prepayments and Reductions of Revolving Loan
      Commitments.

                  (a) Application of Voluntary Prepayments by Type of Loans and
            Order of Maturity. Any voluntary prepayments pursuant to subsection
            2.4B(i) shall be applied as specified by Company in the applicable
            notice of prepayment. In the event Company fails to specify the
            Loans to which any such prepayment shall be applied, such prepayment
            shall be applied first to repay outstanding Swing Line Loans to the
            full extent thereof, second to repay outstanding Revolving Loans to
            the full extent thereof, and third to repay outstanding Term Loans
            to the full extent thereof and any such voluntary prepayments of the
            Term Loans pursuant to subsection 2.4B(i) as to which no such
            application is specified shall be applied to prepay the Tranche A
            Term Loans and the Tranche B Term Loans on a pro rata basis (in
            accordance with the respective outstanding principal amounts
            thereof) and to reduce the scheduled installments of principal of
            the Tranche A Term Loans and Tranche B Term Loans set forth in
            subsections 2.4A(i) and 2.4A(ii) on a pro rata basis (in accordance
            with the respective outstanding principal amounts thereof) to each
            remaining scheduled installment of principal of the Tranche A Term
            Loans or the Tranche B Term Loans, as the case may be, set forth in
            subsection 2.4A(i) or 2.4A(ii), respectively. Notwithstanding the
            foregoing, in the case of any voluntary prepayment of the Tranche B
            Term Loans, Company may elect to offer the Lenders of the Tranche B
            Term Loans the option to waive the right to receive the amount of
            such voluntary prepayment of the Tranche B Term Loans. If any Lender
            or Lenders elect to waive the right to receive the amount of such
            voluntary prepayment, all of the amount that otherwise would have
            been applied to voluntarily prepay the Tranche B Term Loans of such
            Lender or Lenders shall be applied instead to the further prepayment
            of the Tranche A Term Loans to the extent any are then outstanding,
            and thereafter to the voluntary prepayment of the Revolving Loans
            and permanent reduction of the Revolving Loan Commitments.

                  (b) Application of Mandatory Prepayments by Type of Loans.
            Except as provided in subsection 2.4D, any amount required to be
            applied as a mandatory prepayment of the Loans and/or a reduction of
            the Revolving Loan Commitments pursuant to subsections
            2.4B(iii)(a)-(f) shall be applied first to prepay the Term Loans to
            the full extent thereof as provided in subsection 2.4B(iv)(c),
            second, to the extent of any remaining portion of such amount, to
            prepay the Swing Line Loans to the full extent thereof and to
            permanently reduce the Revolving Loan Commitments by the amount of
            such prepayment, third, to the extent of any remaining portion of
            such amount, to prepay the Revolving Loans to the full extent
            thereof and to further permanently reduce the Revolving Loan
            Commitments by the amount of such prepayment, and fourth, to the
            extent of any remaining portion of such amount, to further
            permanently reduce the Revolving Loan Commitments to the full extent
            thereof. Any mandatory reduction of Revolving Loan Commitments
            pursuant to this subsection 2.4B shall be in proportion to each
            Revolving Lender's Pro Rata Share.

                                       45

                  (c) Application of Mandatory Prepayments of Term Loans to
            Tranche A Term Loans and Tranche B Term Loans and the Scheduled
            Installments of Principal Thereof. Any mandatory prepayments of the
            Term Loans pursuant to subsection 2.4B(iii) shall be applied to
            prepay the Tranche A Term Loans and the Tranche B Term Loans on a
            pro rata basis (in accordance with the respective outstanding
            principal amounts thereof). Any such mandatory prepayments applied
            to the Tranche A Term Loans or the Tranche B Term Loans shall be
            applied to reduce the scheduled installments of principal of the
            Tranche A Term Loans or the Tranche B Term Loans, as the case may
            be, set forth in subsection 2.4A(i) or 2.4A(ii), respectively, as
            follows:

                        (1) Net Asset Sale Proceeds, Net Insurance/Condemnation
                  Proceeds and Net Securities Proceeds. Any such mandatory
                  prepayments pursuant to subsections 2.4B(iii)(a), (b), (c) or
                  (d) (and any related such mandatory prepayments pursuant to
                  subsection 2.4B(iii)(f)) shall be applied to reduce such
                  scheduled installments on a pro rata basis (in accordance with
                  the respective outstanding principal amounts thereof) to each
                  such remaining scheduled installment.

                        (2) Consolidated Excess Cash Flow. Any such mandatory
                  prepayments pursuant to subsections 2.4B(iii)(e) (and any
                  related such mandatory prepayments pursuant to subsection
                  2.4B(iii)(f)) shall be applied to reduce such scheduled
                  installments first to the next two scheduled installments in
                  forward chronological order, and then, on a pro rata basis (in
                  accordance with the respective outstanding principal amounts
                  thereof) to each remaining scheduled installment that is
                  unpaid at the time of such prepayment.

            Notwithstanding the foregoing, in the case of any mandatory
            prepayment of the Tranche B Term Loans, Company may elect to offer
            the Lenders of the Tranche B Term Loans the option to waive the
            right to receive the amount of such mandatory prepayment of the
            Tranche B Term Loans. If any Lender or Lenders elect to waive the
            right to receive the amount of such mandatory prepayment, all of the
            amount that otherwise would have been applied to mandatorily prepay
            the Tranche B Term Loans of such Lender or Lenders shall be applied
            instead to the further prepayment of the Tranche A Term Loans to the
            extent any are then outstanding, and thereafter to the mandatory
            prepayment of the Revolving Loans and permanent reduction of the
            Revolving Loan Commitments.

                  (d) Application of Prepayments to Base Rate Loans and
            Eursodollar Rate Loans. Considering Tranche A Term Loans, Tranche B
            Term Loans and Revolving Loans being prepaid separately, any
            prepayment thereof shall be applied first to Base Rate Loans to the
            full extent thereof before application to Eurodollar Rate Loans, in
            each case in a manner which minimizes the amount of any payments
            required to be made by Company pursuant to subsection 2.6D.

            C. GENERAL PROVISIONS REGARDING PAYMENTS.

            (i) Manner and Time of Payment. All payments by Company of
      principal, interest, fees and other Obligations hereunder shall be made in
      Dollars in same day funds, without defense, setoff or counterclaim, free
      of any restriction or condition, and delivered to Administrative Agent not
      later than 12:00 Noon (San Francisco time) on the date due at the Funding
      and Payment Office for the account of Lenders; funds received by
      Administrative Agent after that time on such due date shall be deemed to
      have been paid by Company on the next succeeding Business Day. Company
      hereby authorizes Administrative Agent to charge its accounts with
      Administrative Agent in order to cause timely payment to be made to
      Administrative Agent of all principal, interest, fees and expenses due
      hereunder (subject to sufficient funds being available in its accounts for
      that purpose).

            (ii) Application of Payments to Principal and Interest. Except as
      provided in subsection 2.2C, all payments in respect of the principal
      amount of any Loan shall include payment of accrued interest on the
      principal amount being repaid or prepaid, and all such payments (and, in
      any event, any payments in respect of any Loan on a date when interest is
      due and payable with respect to such Loan) shall be applied to the payment
      of interest before application to principal.

            (iii) Apportionment of Payments. Aggregate principal and interest
      payments in respect of Term Loans and Revolving Loans shall be apportioned
      among all outstanding Loans to which such payments relate, in each case
      proportionately to Lenders' respective Pro Rata Shares. Administrative
      Agent shall promptly distribute to each Lender, at the account specified
      in the payment instructions set forth below its name on the appropriate
      signature page hereof or at such other account as such Lender may request
      in subsequent payment instructions delivered to Administrative Agent by
      such Lender, its Pro Rata Share of all such payments received by
      Administrative Agent and the commitment fees and letter of credit fees of
      such Lender, if any, when received by Administrative Agent pursuant to
      subsection 2.3 and subsection 3.2. Notwithstanding the foregoing
      provisions of this subsection 2.4C(iii), if, pursuant to the provisions of
      subsection 2.6C, any Notice of Conversion/Continuation is withdrawn as to
      any Affected Lender or if any Affected Lender makes Base Rate Loans in
      lieu of its Pro Rata Share of any Eurodollar Rate Loans, Administrative
      Agent shall give effect thereto in apportioning interest payments received
      thereafter.

            (iv) Payments on Business Days. Whenever any payment to be made
      hereunder shall be stated to be due on a day that is not a Business Day,
      such payment shall be made on the next succeeding Business Day and such
      extension of time shall be included in the computation of the payment of
      interest hereunder or of the commitment fees hereunder, as the case may
      be.

            (v) Notation of Payment. Each Lender agrees that before disposing of
      any Note held by it, or any part thereof (other than by granting
      participations therein), that Lender will make a notation thereon of all
      Loans evidenced by that Note and all principal payments previously made
      thereon and of the date to which interest thereon has been

                                       47

<PAGE>

      paid; provided that the failure to make (or any error in the making of) a
      notation of any Loan made under such Note shall not limit or otherwise
      affect the obligations of Company hereunder or under such Note with
      respect to any Loan or any payments of principal or interest on such Note.

            D. APPLICATION OF PROCEEDS OF COLLATERAL AND PAYMENTS AFTER EVENT OF
DEFAULT. Upon the occurrence and during the continuation of an Event of Default,
if requested by Requisite Lenders all payments received on account of the
Secured Obligations, whether from Company, from Holdings or from any Subsidiary
Guarantor or otherwise and all proceeds received by Administrative Agent in
respect of any sale of, collection from, or other realization upon all or any
part of the Collateral under any Collateral Document shall be applied or held by
the Administrative Agent as provided in Section 17 of the Security Agreement.

      2.5   USE OF PROCEEDS.

            A. TERM LOANS. The proceeds of the Term Loans (excluding the
proceeds of Term Loans outstanding under (and as defined in) the Original Credit
Agreement on the Closing Date) shall be used by Company as follows:

      (i) on the Closing Date, up to $22,000,000 shall be used to repurchase,
      redeem, defease or otherwise retire all of the Subordinated Notes;

      (ii) on or prior to March 15, 2004 (or in the case of bonuses to holders
      of employee stock options, when the holders' rights to purchase shares of
      Holdings Common Stock pursuant to such options become vested), up to
      $25,000,000 shall be distributed to PRA Sub, which in turn will distribute
      funds to Holdings, which in turn will (a) purchase shares, or stock
      options or warrants to purchase shares, of Holdings Common Stock, (b)
      purchase, or cause 4063988 Canada Inc. or any other Subsidiary to
      purchase, Exchangeable Shares, (c) make a dividend distribution to holders
      of Holdings Common Stock, (d) make, or cause 4063988 Canada Inc. or any
      other Subsidiary to make, a dividend distribution to holders of
      Exchangeable Shares, and (e) pay bonuses to holders of vested and unvested
      employee stock options to purchase Holdings Common Stock; and

      (iii) to pay the fees payable on the Closing Date referred to in
      subsection 2.3, to pay expenses payable in connection with this Agreement
      pursuant to subsection 10.2, and to pay the fees and expenses payable in
      connection with the transactions contemplated by clause (ii) of this
      subsection 2.5A.

            B. REVOLVING LOANS; SWING LINE LOANS. The proceeds of the Revolving
Loans and any Swing Line Loans shall be applied by Company for working capital
and other general corporate purposes, which may include the making of
intercompany loans to any of Company's wholly-owned Subsidiaries in accordance
with subsection 7.1(iii) for their own general corporate purposes; provided that
the proceeds of the Revolving Loans may be used by Company from time to time to
finance Permitted Acquisitions only if after giving effect to the consummation
of such Permitted Acquisition the unused portion of the Revolving Loan
Commitments is at least $10,000,000.

                                       48

<PAGE>

            C. MARGIN REGULATIONS. No portion of the proceeds of any borrowing
under this Agreement shall be used by Company or any of its Subsidiaries in any
manner that might cause the borrowing or the application of such proceeds to
violate Regulation U, Regulation T or Regulation X of the Board of Governors of
the Federal Reserve System or any other regulation of such Board or to violate
the Exchange Act, in each case as in effect on the date or dates of such
borrowing and such use of proceeds.

      2.6   SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE LOANS.

            Notwithstanding any other provision of this Agreement to the
contrary, the following provisions shall govern with respect to Eurodollar Rate
Loans as to the matters covered:

            A. DETERMINATION OF APPLICABLE INTEREST RATE. On each Interest Rate
Determination Date, Administrative Agent shall determine in accordance with this
Agreement (which determination shall, absent manifest error, be conclusive and
binding upon all parties) the interest rate that shall apply to the Eurodollar
Rate Loans for which an interest rate is then being determined for the
applicable Interest Period and shall promptly give notice thereof (in writing or
by telephone confirmed in writing) to Company and each Lender.

            B. INABILITY TO DETERMINE APPLICABLE INTEREST RATE. In the event
that Administrative Agent shall have determined (which determination shall be
conclusive and binding upon all parties hereto), on any Interest Rate
Determination Date that by reason of circumstances affecting the London
interbank market adequate and fair means do not exist for ascertaining the
interest rate applicable to such Loans on the basis provided for in the
definition of Eurodollar Rate, Administrative Agent shall on such date give
notice (by telefacsimile or by telephone confirmed in writing) to Company and
each Lender of such determination, whereupon (i) no Loans may be made as, or
converted to, Eurodollar Rate Loans until such time as Administrative Agent
notifies Company and Lenders that the circumstances giving rise to such notice
no longer exist and (ii) any Notice of Borrowing or Notice of
Conversion/Continuation given by Company with respect to the Loans in respect of
which such determination was made shall be deemed to be for a Base Rate Loan.

            C. ILLEGALITY OR IMPRACTICABILITY OF EURODOLLAR RATE LOANS. In the
event that on any date any Lender shall have determined (which determination
shall be conclusive and binding upon all parties hereto but shall be made only
after consultation with Company and Administrative Agent) that the making,
maintaining or continuation of its Eurodollar Rate Loans (i) has become unlawful
as a result of compliance by such Lender in good faith with any law, treaty,
governmental rule, regulation, guideline or order (or would conflict with any
such treaty, governmental rule, regulation, guideline or order not having the
force of law even though the failure to comply therewith would not be unlawful)
or (ii) has become impracticable, or would cause such Lender material hardship,
as a result of contingencies occurring after the date of this Agreement which
materially and adversely affect the London interbank market or the position of
such Lender in that market, then, and in any such event, such Lender shall be an
"AFFECTED LENDER" and it shall on that day give notice (by telefacsimile or by
telephone confirmed in writing) to Company and Administrative Agent of such
determination, and Administrative Agent shall promptly notify each other Lender
of the receipt of such notice. Thereafter (a) the

                                       49

<PAGE>

obligation of the Affected Lender to make Loans as, or to convert Loans to,
Eurodollar Rate Loans shall be suspended until such notice shall be withdrawn by
the Affected Lender, (b) to the extent such determination by the Affected Lender
relates to a Eurodollar Rate Loan then being requested by Company pursuant to a
Notice of Borrowing or a Notice of Conversion/Continuation, the Affected Lender
shall make such Loan as (or convert such Loan to, as the case may be) a Base
Rate Loan, (c) the Affected Lender's obligation to maintain its outstanding
Eurodollar Rate Loans (the "AFFECTED LOANS") shall be terminated at the earlier
to occur of the expiration of the Interest Period then in effect with respect to
the Affected Loans or when required by law, and (d) the Affected Loans shall
automatically convert into Base Rate Loans on the date of such termination.
Notwithstanding the foregoing, to the extent a determination by an Affected
Lender as described above relates to a Eurodollar Rate Loan then being requested
by Company pursuant to a Notice of Borrowing or a Notice of
Conversion/Continuation, Company shall have the option, subject to the
provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice of
Conversion/Continuation as to all Lenders by giving notice (by telefacsimile or
by telephone confirmed in writing) to Administrative Agent of such rescission on
the date on which the Affected Lender gives notice of its determination as
described above, and Administrative Agent shall promptly notify each other
Lender of the receipt of such notice. Except as provided in the immediately
preceding sentence, nothing in this subsection 2.6C shall affect the obligation
of any Lender other than an Affected Lender to make or maintain Loans as, or to
convert Loans to, Eurodollar Rate Loans in accordance with the terms of this
Agreement.

            D. COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST
PERIODS. Company shall compensate each Lender, upon written request by that
Lender pursuant to subsection 2.8, for all reasonable losses, expenses and
liabilities (including any interest paid by that Lender to lenders of funds
borrowed by it to make or carry its Eurodollar Rate Loans and any loss, expense
or liability sustained by that Lender in connection with the liquidation or
re-employment of such funds) which that Lender may sustain: (i) if for any
reason (other than a default by that Lender) a borrowing of any Eurodollar Rate
Loan does not occur on a date specified therefor in a Notice of Borrowing or a
telephonic request therefor, or a conversion to or continuation of any
Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of
Conversion/Continuation or a telephonic request therefor, (ii) if any prepayment
(including any prepayment or conversion occasioned by the circumstances
described in subsection 2.6C) or other principal payment or any conversion of
any of its Eurodollar Rate Loans occurs on a date prior to the last day of an
Interest Period applicable to that Loan, (iii) if any prepayment of any of its
Eurodollar Rate Loans is not made on any date specified in a notice of
prepayment given by Company, or (iv) as a consequence of any other default by
Company in the repayment of its Eurodollar Rate Loans when required by the terms
of this Agreement.

            E. BOOKING OF EURODOLLAR RATE LOANS. Any Lender may make, carry or
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of that Lender.

            F. ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR RATE LOANS.
Calculation of all amounts payable to a Lender under this subsection 2.6 and
under subsection 2.7A shall be made as though that Lender had funded each of its
Eurodollar Rate Loans through the purchase of a Eurodollar deposit bearing
interest at the rate obtained pursuant

                                       50

<PAGE>

to clause (i) of the definition of Eurodollar Rate in an amount equal to the
amount of such Eurodollar Rate Loan and having a maturity comparable to the
relevant Interest Period, whether or not its Eurodollar Rate Loans had been
funded in such manner.

            G. EURODOLLAR RATE LOANS AFTER DEFAULT. After the occurrence of and
during the continuation of a Potential Event of Default under subsection 8.1,
8.6, 8.7 or 8.9 or an Event of Default or after the occurrence of and during the
continuation for more than 30 days of a Potential Event of Default under
subsection 8.8, (i) Company may not elect to have a Loan be made or maintained
as, or converted to, a Eurodollar Rate Loan after the expiration of any Interest
Period then in effect for that Loan and (ii) subject to the provisions of
subsection 2.6D, any Notice of Borrowing or Notice of Conversion/Continuation
given by Company with respect to a requested borrowing or
conversion/continuation that has not yet occurred shall be deemed to be for a
Base Rate Loan or, if the conditions to making a Loan set forth in subsection
4.2 cannot then be satisfied, to be rescinded by Company.

      2.7   INCREASED COSTS; TAXES; CAPITAL ADEQUACY.

            A. COMPENSATION FOR INCREASED COSTS. Subject to the provisions of
subsection 2.7B (which shall be controlling with respect to the matters covered
thereby), in the event that any Lender (including any Issuing Lender) shall
determine (which determination shall, absent manifest error, be final and
conclusive and binding upon all parties hereto) that any law, treaty or
governmental rule, regulation or order, or any change therein or in the
interpretation, administration or application thereof (including the
introduction of any new law, treaty or governmental rule, regulation or order),
or any determination of a court or other Government Authority, in each case that
becomes effective after the date hereof, or compliance by such Lender with any
guideline, request or directive issued or made after the date hereof by any
central bank or other Government Authority (whether or not having the force of
law):

            (i) subjects such Lender to any additional Tax with respect to this
      Agreement or any of its obligations hereunder (including with respect to
      issuing or maintaining any Letters of Credit or purchasing or maintaining
      any participations therein or maintaining any Commitment hereunder) or any
      payments to such Lender of principal, interest, fees or any other amount
      payable hereunder;

            (ii) imposes, modifies or holds applicable any reserve, special
      deposit, compulsory loan, insurance charge or similar requirement against
      assets held by, or deposits or other liabilities in or for the account of,
      or advances or loans by, or other credit extended by, or any other
      acquisition of funds by, any office of such Lender (other than any such
      reserve or other requirements with respect to Eurodollar Rate Loans that
      are reflected in the definition of Eurodollar Rate); or

            (iii) imposes any other condition (other than with respect to Taxes)
      on or affecting such Lender or its obligations hereunder or the London
      interbank market;

and the result of any of the foregoing is to increase the cost to such Lender of
agreeing to make, making or maintaining its Loans or Commitments or agreeing to
issue, issuing or maintaining any Letter of Credit or agreeing to purchase,
purchasing or maintaining any participation therein

                                       51

or to reduce any amount received or receivable by such Lender with respect
thereto; then, in any such case, Company shall promptly pay to such Lender, upon
receipt of the statement referred to in subsection 2.8A, such additional amount
or amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as such Lender in its sole discretion shall
determine) as may be necessary to compensate such Lender for any such increased
cost or reduction in amounts received or receivable hereunder; provided that
Company shall not be required to compensate a Lender pursuant to this subsection
for any increased cost in respect of a period occurring more than 180 days prior
to the date that such Lender notifies Company of such Lender's intention to
claim compensation therefor unless the circumstances giving rise to such
increased cost become applicable retroactively, in which case no such time limit
shall apply so long as such Lender requests compensation within 180 days from
the date such circumstances become applicable.

      B.    TAXES.

            (i) Payments to Be Free and Clear. Except as otherwise provided in
      subsection 2.7B(ii), all sums payable by Company under this Agreement and
      the other Loan Documents shall be paid free and clear of, and without any
      deduction or withholding on account of, any Tax imposed, levied,
      collected, withheld or assessed by or within the United States or any
      political subdivision in or of the United States or any other jurisdiction
      from or to which a payment is made by or on behalf of Company or by any
      federation or organization of which the United States or any such
      jurisdiction is a member at the time of payment.

            (ii) Grossing-up of Payments. If Company or any other Person is
      required by law to make any deduction or withholding on account of any
      such Tax from any sum paid or payable by Company to Administrative Agent
      or any Lender under any of the Loan Documents:

                  (a) Company shall notify Administrative Agent of any such
            requirement or any change in any such requirement as soon as Company
            becomes aware of it;

                  (b) Company shall pay any such Tax when such Tax is due, such
            payment to be made (if the liability to pay is imposed on Company)
            for its own account or (if that liability is imposed on
            Administrative Agent or such Lender, as the case may be) on behalf
            of and in the name of Administrative Agent or such Lender;

                  (c) the sum payable by Company in respect of which the
            relevant deduction, withholding or payment is required shall be
            increased to the extent necessary to ensure that, after the making
            of that deduction, withholding or payment, Administrative Agent or
            such Lender, as the case may be, receives on the due date a net sum
            equal to what it would have received had no such deduction,
            withholding or payment been required or made; and

                                       52

<PAGE>

                  (d) within 30 days after paying any sum from which it is
            required by law to make any deduction or withholding, and within 30
            days after the due date of payment of any Tax which it is required
            by clause (b) above to pay, Company shall deliver to Administrative
            Agent evidence satisfactory to the other affected parties of such
            deduction, withholding or payment and of the remittance thereof to
            the relevant taxing or other authority;

provided that no such additional amount shall be required to be paid to any
Lender under clause (c) above except to the extent that any change after the
date on which such Lender became a Lender in any such requirement for a
deduction, withholding or payment as is mentioned therein shall result in an
increase in the rate of such deduction, withholding or payment from that in
effect on the date on which such Lender became a Lender, in respect of payments
to such Lender.

            (iii) Evidence of Exemption from U.S. Withholding Tax.

                  (a) Each Non-US Lender shall deliver to Administrative Agent
            and to Company, on or prior to the Closing Date (in the case of each
            Lender listed on the signature pages hereof) or on or prior to the
            date of the Assignment Agreement pursuant to which it becomes a
            Lender (in the case of each other Lender), and at such other times
            as may be necessary in the determination of Company or
            Administrative Agent (each in the reasonable exercise of its
            discretion), two original copies of Internal Revenue Service Form
            W-8BEN or W-8ECI (or any successor forms) properly completed and
            duly executed by such Lender, or, in the case of a Non-US Lender
            claiming exemption from United States federal withholding tax under
            Section 871(h) or 881(c) of the Internal Revenue Code with respect
            to payments of "portfolio interest", a form W-8BEN, and, in the case
            of a Lender that has certified in writing to Administrative Agent
            that it is not a "bank" (as defined in Section 881(c)(3)(A) of the
            Internal Revenue Code), a certificate of such Lender certifying that
            such Lender is not (i) a "bank" for purposes of Section 881(c) of
            the Internal Revenue Code, (ii) a ten-percent shareholder (within
            the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of
            Company, PRA Sub or Holdings or (iii) a controlled foreign
            corporation related to Company (within the meaning of Section
            864(d)(4) of the Internal Revenue Code), in each case together with
            any other certificate or statement of exemption required under the
            Internal Revenue Code or the regulations issued thereunder to
            establish that such Lender is not subject to United States
            withholding tax with respect to any payments to such Lender of
            interest payable under any of the Loan Documents.

                  (b) Each Non-US Lender, to the extent it does not act or
            ceases to act for its own account with respect to any portion of any
            sums paid or payable to such Lender under any of the Loan Documents
            (for example, in the case of a typical participation by such
            Lender), shall deliver to Administrative Agent and to Company, on or
            prior to the Closing Date (in the case of each Lender listed on the
            signatures pages hereof), on or prior to the date of the Assignment
            Agreement pursuant to which it becomes a Lender (in the case of each
            other Lender), or on such later date when such Lender ceases to act
            for its own account with respect to

                                       53

<PAGE>

            any portion of any such sums paid or payable, and at such other
            times as may be necessary in the determination of Company or
            Administrative Agent (each in the reasonable exercise of its
            discretion), (1) two original copies of the forms or statements
            required to be provided by such Lender under subsection
            2.7B(iii)(a), properly completed and duly executed by such Lender,
            establishing that the portion of any such sums paid or payable with
            respect to which such Lender acts for its own account is not subject
            to United States withholding tax, and (2) two original copies of
            Internal Revenue Service Form W-8IMY (or any successor forms)
            properly completed and duly executed by such Lender, together with
            any information, if any, such Lender chooses to transmit with such
            form, and any other certificate or statement of exemption required
            under the Internal Revenue Code or the regulations issued
            thereunder, to establish that such Lender is not acting for its own
            account with respect to a portion of any such sums payable to such
            Lender.

                  (c) Each Non-US Lender hereby agrees, from time to time after
            the initial delivery by such Lender of such forms, whenever a lapse
            in time or change in circumstances renders such forms, certificates
            or other evidence so delivered obsolete or inaccurate in any
            material respect, that such Lender shall promptly (1) deliver to
            Administrative Agent and to Company two original copies of renewals,
            amendments or additional or successor forms, properly completed and
            duly executed by such Lender, together with any other certificate or
            statement of exemption required in order to confirm or establish
            that such Lender is not subject to United States withholding tax
            with respect to payments to such Lender under the Loan Documents
            and, if applicable, that such Lender does not act for its own
            account with respect to any portion of such payment, or (2) notify
            Administrative Agent and Company of its inability to deliver any
            such forms, certificates or other evidence.

                  (d) Company shall not be required to pay any additional amount
            to any Non-US Lender under clause (c) of subsection 2.7B(ii) if such
            Lender shall have failed to satisfy the requirements of clause (a),
            (b) or (c)(1) of this subsection 2.7B(iii); provided that if such
            Lender shall have satisfied the requirements of subsection
            2.7B(iii)(a) on the date such Lender became a Lender, nothing in
            this subsection 2.7B(iii)(d) shall relieve Company of its obligation
            to pay any amounts pursuant to subsection 2.7B(ii)(c) in the event
            that, as a result of any change in any applicable law, treaty or
            governmental rule, regulation or order, or any change in the
            interpretation, administration or application thereof, such Lender
            is no longer properly entitled to deliver forms, certificates or
            other evidence at a subsequent date establishing the fact that such
            Lender is not subject to withholding as described in subsection
            2.7B(iii)(a).

            C. CAPITAL ADEQUACY ADJUSTMENT. If any Lender shall have determined
that the adoption, effectiveness, phase-in or applicability, in each case after
the date hereof, of any law, rule or regulation (or any provision thereof)
regarding capital adequacy, or any change after the date hereof therein or in
the interpretation or administration thereof by any Government Authority charged
with the interpretation or administration thereof, or compliance by any Lender

                                       54

<PAGE>

with any guideline, request or directive regarding capital adequacy (whether or
not having the force of law) of any such Government Authority, has or would have
the effect of reducing the rate of return on the capital of such Lender or any
corporation controlling such Lender as a consequence of, or with reference to,
such Lender's Loans or Commitments or Letters of Credit or participations
therein or other obligations hereunder with respect to the Loans or the Letters
of Credit to a level below that which such Lender or such controlling
corporation could have achieved but for such adoption, effectiveness, phase-in,
applicability, change or compliance (taking into consideration the policies of
such Lender or such controlling corporation with regard to capital adequacy),
then from time to time, within five Business Days after receipt by Company from
such Lender of the statement referred to in subsection 2.8A, Company shall pay
to such Lender such additional amount or amounts as will compensate such Lender
or such controlling corporation on an after-tax basis for such reduction;
provided that Company shall not be required to compensate a Lender pursuant to
this subsection for any increased cost or reduction in respect of a period
occurring more than 180 days prior to the date that such Lender notifies Company
of such Lender's intention to claim compensation therefor unless the
circumstances giving rise to such increased cost or reduction become applicable
retroactively, in which case no such time limit shall apply so long as such
Lender requests compensation within 180 days from the date such circumstances
become applicable.

      2.8   STATEMENT OF LENDERS; OBLIGATION OF LENDERS AND ISSUING LENDERS TO
            MITIGATE.

            A. STATEMENTS. Each Lender claiming compensation or reimbursement
pursuant to subsection 2.6D, 2.7 or 2.8B shall deliver to Company (with a copy
to Administrative Agent) a written statement, setting forth in reasonable detail
the basis of the calculation of such compensation or reimbursement, which
statement shall be conclusive and binding upon all parties hereto absent
manifest error.

            B. MITIGATION. Each Lender and Issuing Lender agrees that, as
promptly as practicable after the officer of such Lender or Issuing Lender
responsible for administering the Loans or Letters of Credit of such Lender or
Issuing Lender, as the case may be, becomes aware of the occurrence of an event
or the existence of a condition that would cause such Lender to become an
Affected Lender or that would entitle such Lender or Issuing Lender to receive
payments under subsection 2.7, use commercially reasonable effort to make,
issue, fund or maintain the Commitments of such Lender or the Affected Loans or
Letters of Credit of such Lender or Issuing Lender through another lending or
letter of credit office of such Lender or Issuing Lender, if (i) as a result
thereof the circumstances which would cause such Lender to be an Affected Lender
would cease to exist or the additional amounts which would otherwise be required
to be paid to such Lender or Issuing Lender pursuant to subsection 2.7 would be
materially reduced and (ii) as determined by such Lender or Issuing Lender in
its sole discretion, such action would not otherwise be disadvantageous to such
Lender or Issuing Lender; provided that such Lender or Issuing Lender will not
be obligated to utilize such other lending or letter of credit office pursuant
to this subsection 2.8B unless Company agrees to pay all incremental expenses
incurred by such Lender or Issuing Lender as a result of utilizing such other
lending or letter of credit office as described above.

      2.9   REPLACEMENT OF A LENDER.

                                       55

<PAGE>

            If Company receives a statement of amounts due pursuant to
subsection 2.8A from a Lender, a Revolving Lender defaults in its obligations to
fund a Revolving Loan pursuant to this Agreement, or a Lender becomes an
Affected Lender (any such Lender, a "SUBJECT LENDER"), so long as (i) no
Potential Event of Default under subsection 8.1, 8.6, 8.7 or 8.9 or Event of
Default shall have occurred and be continuing and no Potential Event of Default
under subsection 8.8 shall have occurred and be continuing for more than 30 days
and Company has obtained a commitment from another Lender or an Eligible
Assignee to purchase at par the Subject Lender's Loans and assume the Subject
Lender's Commitments and all other obligations of the Subject Lender hereunder,
(ii) such Lender is not an Issuing Lender with respect to any Letters of Credit
outstanding (unless all such Letters of Credit are terminated or arrangements
reasonably acceptable to such Issuing Lender (such as a "back-to-back" letter of
credit) are made) and (iii), if applicable, the Subject Lender is unwilling to
withdraw the notice delivered to Company pursuant to subsection 2.8 and/or is
unwilling to remedy its default upon 10 days prior written notice to the Subject
Lender and Administrative Agent, Company may require the Subject Lender to
assign all of its Loans and Commitments to such other Lender, Lenders, Eligible
Assignee or Eligible Assignees pursuant to the provisions of subsection 10.1B;
provided that, prior to or concurrently with such replacement, (1) the Subject
Lender shall have received payment in full of all principal, interest, fees and
other amounts (including all amounts under subsections 2.6D, 2.7 and/or 2.8B (if
applicable)) through such date of replacement and a release from its obligations
under the Loan Documents, (2) the processing fee required to be paid by
subsection 10.1B(i) shall have been paid to Administrative Agent, and (3) all of
the requirements for such assignment contained in subsection 10.1B, including,
without limitation, the consent of Administrative Agent (if required) and the
receipt by Administrative Agent of an executed Assignment Agreement and other
supporting documents, have been fulfilled

SECTION 3. LETTERS OF CREDIT

      3.1   ISSUANCE OF LETTERS OF CREDIT AND LENDERS' PURCHASE OF
            PARTICIPATIONS THEREIN.

            A. LETTERS OF CREDIT. In addition to Company requesting that Lenders
make Revolving Loans pursuant to subsection 2.1A(iii) and that Swing Line Lender
make Swing Line Loans pursuant to subsection 2.1A(iv), Company may request, in
accordance with the provisions of this subsection 3.1, from time to time during
the period from the Closing Date to but excluding the 30th day prior to the
Revolving Loan Commitment Termination Date, that one or more Revolving Lenders
issue Letters of Credit payable on a sight basis for the account of Company for
the purposes specified in the definition of Letters of Credit. Subject to the
terms and conditions of this Agreement and in reliance upon the representations
and warranties of Company herein set forth, any one or more Lenders may, but
(except as provided in subsection 3.1B(ii)) shall not be obligated to, issue
such Letters of Credit in accordance with the provisions of this subsection 3.1;
provided that Company shall not request that any Revolving Lender issue (and no
Revolving Lender shall issue):

            (i) any Letter of Credit if, after giving effect to such issuance,
      the Total Utilization of Revolving Loan Commitments would exceed the
      Revolving Loan Commitments then in effect;

                                       56

<PAGE>

            (ii) any Letter of Credit if, after giving effect to such issuance,
      the Letter of Credit Usage would exceed $7,500,000;

            (iii) except with respect to the Letters of Credit set forth on
      Schedule 3.1(a) annexed hereto, any Letter of Credit having an expiration
      date later than the earlier of (a) ten days prior to the Revolving Loan
      Commitment Termination Date and (b) the date which is one year from the
      date of issuance of such Letter of Credit; provided that the immediately
      preceding clause (b) shall not prevent any Issuing Lender from agreeing
      that a Letter of Credit will automatically be extended for one or more
      successive periods not to exceed one year each unless such Issuing Lender
      elects not to extend for any such additional period; and provided, further
      that such Issuing Lender shall elect not to extend such Letter of Credit
      if it has knowledge that an Event of Default has occurred and is
      continuing (and has not been waived in accordance with subsection 10.6) at
      the time such Issuing Lender must elect whether or not to allow such
      extension;

            (iv) any Letter of Credit issued for the purpose of supporting (a)
      trade payables or (b) any Indebtedness constituting "antecedent debt" (as
      that term is used in Section 547 of the Bankruptcy Code); and

            (v) any Letter of Credit denominated in a currency other than
      Dollars, the Euro, Pound Sterling, South African Rand, Australian Dollars
      or Yen.

            On and after the Closing Date, the Letters of Credit outstanding
under (and as defined in) the Original Credit Agreement as of the Closing Date,
set forth on Schedule 3.1(b) attached hereto, shall be automatically deemed for
all purposes to be Letters of Credit outstanding under this Agreement and shall
be subject to all of the terms and conditions of this Agreement and the other
Loan Documents.

            B. MECHANICS OF ISSUANCE.

            (i) Request for Issuance. Whenever Company desires the issuance of a
      Letter of Credit, it shall deliver to the proposed Issuing Lender (with a
      copy to Administrative Agent if Administrative Agent is not the proposed
      Issuing Lender) a Request for Issuance no later than 9:00 A.M. (San
      Francisco time) at least three Business Days, or such shorter period as
      may be agreed to by the Issuing Lender in any particular instance, in
      advance of the proposed date of issuance. The Issuing Lender, in its
      reasonable discretion, may require changes in the text of the proposed
      Letter of Credit or any documents described in or attached to the Request
      for Issuance. No Letter of Credit shall require payment against a
      conforming demand for payment to be made thereunder on the same business
      day (under the laws of the jurisdiction in which the office of the Issuing
      Lender to which such demand for payment is required to be presented is
      located) that such demand for payment is presented if such presentation is
      made after 10:00 A.M. (in the time zone of such office of the Issuing
      Lender) on such business day.

            Company shall notify the applicable Issuing Lender (and
      Administrative Agent, if Administrative Agent is not such Issuing Lender)
      prior to the issuance of any Letter of Credit in the event that any of the
      matters to which Company is required to certify in the

                                       57

<PAGE>

      applicable Request for Issuance is no longer true and correct as of the
      proposed date of issuance of such Letter of Credit, and upon the issuance
      of any Letter of Credit Company shall be deemed to have re-certified, as
      of the date of such issuance, as to the matters to which Company is
      required to certify in the applicable Request for Issuance.

            (ii) Determination of Issuing Lender. Upon receipt by a proposed
      Issuing Lender of a Request for Issuance pursuant to subsection 3.1B(i)
      requesting the issuance of a Letter of Credit, (a) in the event
      Administrative Agent is the proposed Issuing Lender, Administrative Agent
      shall be the Issuing Lender with respect to such Letter of Credit,
      notwithstanding the fact that the Letter of Credit Usage with respect to
      such Letter of Credit and with respect to all other Letters of Credit
      issued by Administrative Agent, when aggregated with Administrative
      Agent's outstanding Revolving Loans and Swing Line Loans, may exceed
      Administrative Agent's Revolving Loan Commitment then in effect; provided
      that Administrative Agent shall not be obligated to issue any Letter of
      Credit denominated in a foreign currency which in the judgment of
      Administrative Agent is not readily and freely available, and (b) in the
      event any other Revolving Lender is the proposed Issuing Lender, such
      Revolving Lender shall promptly notify Company and Administrative Agent
      whether or not, in its sole discretion, it has elected to issue such
      Letter of Credit, and (1) if such Revolving Lender so elects to issue such
      Letter of Credit it shall be the Issuing Lender with respect thereto and
      (2) if such Revolving Lender fails to so promptly notify Company and
      Administrative Agent or declines to issue such Letter of Credit, Company
      may request Administrative Agent or another Revolving Lender to be the
      Issuing Lender with respect to such Letter of Credit in accordance with
      the provisions of this subsection 3.1B.

            (iii) Issuance of Letter of Credit. Upon satisfaction or waiver (in
      accordance with subsection 10.6) of the conditions set forth in subsection
      4.3, the Issuing Lender shall issue the requested Letter of Credit in
      accordance with the Issuing Lender's standard operating procedures.

            (iv) Notification to Revolving Lenders. Upon the issuance of or
      amendment to any Letter of Credit, Administrative Agent shall notify each
      Revolving Lender in writing of such issuance or amendment and the amount
      of such Revolving Lender's respective participation in such Letter of
      Credit or amendment, and, if so requested by a Revolving Lender,
      Administrative Agent shall provide such Lender with a copy of such Letter
      of Credit or amendment.

            C. REVOLVING LENDERS' PURCHASE OF PARTICIPATIONS IN LETTERS OF
CREDIT. Immediately upon the issuance of each Letter of Credit, each Revolving
Lender shall be deemed to, and hereby agrees to, have irrevocably purchased from

of the maximum amount which is or at any time may become available to be drawn

                                       58

            Company agrees to pay the following amounts with respect to Letters
of Credit issued hereunder:

            (i) a fronting fee, payable directly to the applicable Issuing
      Lender for its own account, equal to 0.25% per annum of the daily amount
      available to be drawn under such Letter of Credit;

            (ii) a letter of credit fee, payable to Administrative Agent for the
      account of Revolving Lenders, equal to the applicable Eurodollar Rate
      Margin for Revolving Loans per annum of the daily amount available to be
      drawn under such Letter of Credit, each such fronting fee or letter of
      credit fee to be payable in arrears on and to (but excluding) each March
      31, June 30, September 30 and December 31 of each year and computed on the
      basis of a 360-day year for the actual number of days elapsed; and

            (iii) with respect to the issuance, amendment or transfer of each
      Letter of Credit and each payment of a drawing made thereunder (without
      duplication of the fees payable under clauses (i) and (ii) above),
      customary documentary and processing charges payable directly to the
      applicable Issuing Lender for its own account in accordance with the
      applicable Issuing Lender's standard schedule for such charges in effect
      at the time of such issuance, amendment, transfer or payment, as the case
      may be.

            For purposes of calculating any fees payable under clauses (i) and
(ii) of this subsection 3.2, (1) the daily amount available to be drawn under
any Letter of Credit shall be determined as of the close of business on any date
of determination and (2) any amount described in such clauses which is
denominated in a currency other than Dollars shall be valued based on the
applicable Exchange Rate for such currency as of the applicable date of
determination. Promptly upon receipt by Administrative Agent of any amount
described in clause (ii) of this subsection 3.2, Administrative Agent shall
distribute to each Revolving Lender its Pro Rata Share of such amount.

      3.3   DRAWINGS AND REIMBURSEMENT OF AMOUNTS PAID UNDER LETTERS OF CREDIT.

            A. RESPONSIBILITY OF ISSUING LENDER WITH RESPECT TO DRAWINGS. In
determining whether to honor any drawing under any Letter of Credit by the
beneficiary thereof, the applicable Issuing Lender shall be responsible only to
examine the documents delivered under such Letter of Credit with reasonable care
so as to ascertain whether they appear on their face to be in accordance with
the terms and conditions of such Letter of Credit.

            B. REIMBURSEMENT BY COMPANY OF AMOUNTS PAID UNDER LETTERS OF CREDIT.
In the event any Issuing Lender has determined to honor a drawing under a Letter
of Credit issued by it, such Issuing Lender shall immediately notify Company and
Administrative Agent, and Company shall reimburse such Issuing Lender on or
before the Business Day immediately following the date on which such drawing is
honored (the "REIMBURSEMENT DATE") in an amount in Dollars (which amount, in the
case of a payment under a Letter of Credit which is denominated in a currency
other than Dollars, shall be calculated by reference to the applicable Exchange
Rate) and in same day funds equal to the amount of such payment; provided that,
anything contained in this Agreement to the contrary notwithstanding, (i) unless
Company shall

                                       59

<PAGE>

have notified Administrative Agent prior to 10:00 A.M. (San Francisco time) on
the date such drawing is honored that Company intends to reimburse such Issuing
Lender for the amount of such payment with funds other than the proceeds of
Revolving Loans, Company shall be deemed to have given a timely Notice of
Borrowing to Administrative Agent requesting Revolving Lenders to make Revolving
Loans that are Base Rate Loans on the Reimbursement Date in an amount in Dollars
(which amount, in the case of a payment under a Letter of Credit which is
denominated in a currency other than Dollars, shall be calculated by reference
to the applicable Exchange Rate) equal to the amount of such payment and (ii)
subject to satisfaction or waiver of the conditions specified in subsection
4.2B, Revolving Lenders shall, on the Reimbursement Date, make Revolving Loans
that are Base Rate Loans in the amount of such payment, the proceeds of which
shall be applied directly by Administrative Agent to reimburse such Issuing
Lender for the amount of such payment; and provided, further that if for any
reason proceeds of Revolving Loans are not received by such Issuing Lender on
the Reimbursement Date in an amount equal to the amount of such payment, Company
shall reimburse such Issuing Lender, on demand, in an amount in same day funds
equal to the excess of the amount of such payment over the aggregate amount of
such Revolving Loans, if any, which are so received. Nothing in this subsection
3.3B shall be deemed to relieve any Revolving Lender from its obligation to make
Revolving Loans on the terms and conditions set forth in this Agreement, and
Company shall retain any and all rights it may have against any Revolving Lender
resulting from the failure of such Revolving Lender to make such Revolving Loans
under this subsection 3.3B.

            C. PAYMENT BY LENDERS OF UNREIMBURSED AMOUNTS PAID UNDER LETTERS OF
CREDIT.

            (i) Payment by Revolving Lenders. In the event that Company shall
      fail for any reason to reimburse any Issuing Lender as provided in
      subsection 3.3B in an amount (calculated, in the case of a payment under a
      Letter of Credit denominated in a currency other than Dollars, by
      reference to the applicable Exchange Rate) equal to the amount of any
      payment by such Issuing Lender under a Letter of Credit issued by it, such
      Issuing Lender shall promptly notify each other Lender of the unreimbursed
      amount of such honored drawing and of such other Revolving Lender's
      respective participation therein based on such Revolving Lender's Pro Rata
      Share. Each Revolving Lender shall make available to such Issuing Lender
      an amount equal to its respective participation, in Dollars and in same
      day funds, at the office of such Issuing Lender specified in such notice,
      not later than 12:00 Noon (San Francisco time) on the first business day
      (under the laws of the jurisdiction in which such office of such Issuing
      Lender is located) after the date notified by such Issuing Lender. In the
      event that any Revolving Lender fails to make available to such Issuing
      Lender on such business day the amount of such Revolving Lender's
      participation in such Letter of Credit as provided in this subsection
      3.3C, such Issuing Lender shall be entitled to recover such amount on
      demand from such Revolving Lender together with interest thereon at the
      rate customarily used by such Issuing Lender for the correction of errors
      among banks for three Business Days and thereafter at the Base Rate.
      Nothing in this subsection 3.3C shall be deemed to prejudice the right of
      any Lender to recover from any Issuing Lender any amounts made available
      by such Revolving Lender to such Issuing Lender pursuant to this
      subsection 3.3C in the event that it is determined by the final judgment
      of a court of competent jurisdiction that the payment with respect to a
      Letter of Credit by such Issuing Lender in respect of which

                                       60

<PAGE>

      payment was made by such Revolving Lender constituted gross negligence or
      willful misconduct on the part of such Issuing Lender.

            (ii) Distribution to Lenders of Reimbursements Received From
      Company. In the event any Issuing Lender shall have been reimbursed by
      other Revolving Lenders pursuant to subsection 3.3C(i) for all or any
      portion of any payment by such Issuing Lender under a Letter of Credit
      issued by it, such Issuing Lender shall distribute to each other Revolving
      Lender that has paid all amounts payable by it under subsection 3.3C(i)
      with respect to such payment such other Revolving Lender's Pro Rata Share
      of all payments subsequently received by such Issuing Lender from Company
      in reimbursement of such payment under the Letter of Credit when such
      payments are received. Any such distribution shall be made to a Revolving
      Lender at its primary address set forth below its name on the appropriate
      signature page hereof or at such other address as such Revolving Lender
      may request.

            D. INTEREST ON AMOUNTS PAID UNDER LETTERS OF CREDIT.

            (i) Payment of Interest by Company. Company agrees to pay to each
      Issuing Lender, with respect to payments under any Letters of Credit
      issued by it, interest on the amount paid by such Issuing Lender in
      respect of each such payment from the date a drawing is honored to but
      excluding the date such amount is reimbursed by Company (including any
      such reimbursement out of the proceeds of Revolving Loans pursuant to
      subsection 3.3B) at a rate equal to (a) for the period from the date such
      drawing is honored to but excluding the Reimbursement Date, the rate then
      in effect under this Agreement with respect to Revolving Loans that are
      Base Rate Loans and (b) thereafter, a rate which is 2% per annum in excess
      of the rate of interest otherwise payable under this Agreement with
      respect to Revolving Loans that are Base Rate Loans. Interest payable
      pursuant to this subsection 3.3D(i) shall be computed on the basis of a
      360-day year for the actual number of days elapsed in the period during
      which it accrues and shall be payable on demand or, if no demand is made,
      on the date on which the related drawing under a Letter of Credit is
      reimbursed in full.

            (ii) Distribution of Interest Payments by Issuing Lender. Promptly
      upon receipt by any Issuing Lender of any payment of interest pursuant to
      subsection 3.3D(i) with respect to a payment under a Letter of Credit
      issued by it, (a) such Issuing Lender shall distribute to each other
      Revolving Lender, out of the interest received by such Issuing Lender in
      respect of the period from the date such drawing is honored to but
      excluding the date on which such Issuing Lender is reimbursed for the
      amount of such payment (including any such reimbursement out of the
      proceeds of Revolving Loans pursuant to subsection 3.3B), the amount that
      such other Revolving Lender would have been entitled to receive in respect
      of the letter of credit fee that would have been payable in respect of
      such Letter of Credit for such period pursuant to subsection 3.2 if no
      drawing had been honored under such Letter of Credit, and (b) in the event
      such Issuing Lender shall have been reimbursed by other Revolving Lenders
      pursuant to subsection 3.3C(i) for all or any portion of such payment,
      such Issuing Lender shall distribute to each other Revolving Lender that
      has paid all amounts payable by it under subsection 3.3C(i) with respect
      to such payment such other Revolving Lender's Pro Rata Share of

                                       61

<PAGE>

      any interest received by such Issuing Lender in respect of that portion of
      such payment so reimbursed by other Revolving Lenders for the period from
      the date on which such Issuing Lender was so reimbursed by other Revolving
      Lenders to but excluding the date on which such portion of such payment is
      reimbursed by Company. Any such distribution shall be made to a Revolving
      Lender at its primary address set forth below its name on the appropriate
      signature page hereof or at such other address as such Revolving Lender
      may request.

      3.4   OBLIGATIONS ABSOLUTE.

            The obligation of Company to reimburse any Issuing Lender for
payments under the Letters of Credit issued by it and to repay any Revolving
Loans made by Revolving Lenders pursuant to subsection 3.3B and the obligations
of Revolving Lenders under subsection 3.3C(i) shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances including any of the following circumstances:

            (i) any lack of validity or enforceability of any Letter of Credit;

            (ii) the existence of any claim, set-off, defense or other right
      which Company or any Lender may have at any time against a beneficiary or
      any transferee of any Letter of Credit (or any Persons for whom any such
      transferee may be acting), any Issuing Lender or other Revolving Lender or
      any other Person or, in the case of a Revolving Lender, against Company,
      whether in connection with this Agreement, the transactions contemplated
      herein or any unrelated transaction (including any underlying transaction
      between Company or one of its Subsidiaries and the beneficiary for which
      any Letter of Credit was procured);

            (iii) any draft or other document presented under any Letter of
      Credit proving to be forged, fraudulent, invalid or insufficient in any
      respect or any statement therein being untrue or inaccurate in any
      respect;

            (iv) payment by any Issuing Lender under any Letter of Credit
      against presentation of a draft or other document which does not
      substantially comply with the terms of such Letter of Credit;

      similar to any of the foregoing; or

            (viii) the fact that an Event of Default or a Potential Event of
      Default shall have occurred and be continuing;

                                       62

<PAGE>

provided, in each case, that payment by any Issuing Lender under the applicable
Letter of Credit shall not have constituted gross negligence or willful
misconduct of such Issuing Lender under the circumstances in question (as
determined by a final judgment of a court of competent jurisdiction).

      3.5   INDEMNIFICATION; NATURE OF ISSUING LENDERS' DUTIES.

            A. INDEMNIFICATION. In addition to amounts payable as provided in
subsection 2.7, Company hereby agrees to protect, indemnify, pay and save
harmless each Issuing Lender from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
fees, expenses and disbursements of outside counsel and allocated costs of
internal counsel) which such Issuing Lender may incur or be subject to as a
consequence, direct or indirect, of (i) the issuance of any Letter of Credit by
such Issuing Lender, other than as a result of (a) the gross negligence or
willful misconduct of such Issuing Lender as determined by a final judgment of a
court of competent jurisdiction or (b) subject to the following clause (ii), the
wrongful dishonor by such Issuing Lender of a proper demand for payment made
under any Letter of Credit issued by it or (ii) the failure of such Issuing
Lender to honor a drawing under any such Letter of Credit as a result of any act
or omission, whether rightful or wrongful, of any present or future de jure or
de facto Government Authority.

            B. NATURE OF ISSUING LENDERS' DUTIES. As between Company and any
Issuing Lender, Company assumes all risks of the acts and omissions of, or
misuse of the Letters of Credit issued by such Issuing Lender by, the respective
beneficiaries of such Letters of Credit. In furtherance and not in limitation of
the foregoing, no Issuing Lender shall be responsible for: (i) the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
any such Letter of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) failure of the beneficiary of
any such Letter of Credit to comply fully with any conditions required in order
to draw upon such Letter of Credit; (iv) errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex or otherwise, whether or not they be in cipher; (v) errors in
interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any such
Letter of Credit or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing under
such Letter of Credit; or (viii) any consequences arising from causes beyond the
control of such Issuing Lender, including any act or omission by a Government
Authority specified in subsection 3.5A, and none of the above shall affect or
impair, or prevent the vesting of, any of the Issuing Lender's rights or powers
hereunder.

            In furtherance and extension and not in limitation of the specific
provisions set forth in the first paragraph of this subsection 3.5B, any action
taken or omitted by any Issuing Lender under or in connection with the Letters
of Credit issued by it or any documents and certificates delivered thereunder,
if taken or omitted in good faith, shall not put such Issuing Lender under any
resulting liability to Company.

                                       63

<PAGE>

            Notwithstanding anything to the contrary contained in this
subsection 3.5, Company shall retain any and all rights it may have against any
Issuing Lender for any liability arising solely out of the gross negligence or
willful misconduct of such Issuing Lender, as determined by a final judgment of
a court of competent jurisdiction.

SECTION 5. COMPANY'S REPRESENTATIONS AND WARRANTIES

            In order to induce Lenders to enter into this Agreement and to make
the Loans, to induce the Issuing Lenders to issue Letters of Credit and to
induce Revolving Lenders to purchase participations therein, Company represents
and warrants to each Lender:

      5.1   ORGANIZATION, POWERS, QUALIFICATION, GOOD STANDING, BUSINESS AND
            SUBSIDIARIES.

            A. ORGANIZATION AND POWERS. Each Loan Party is a corporation,
partnership, trust or limited liability company duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization as
specified in Schedule 5.1 annexed hereto as said Schedule 5.1 may be
supplemented from time to time pursuant to the provisions of subsection 6.1(xv).
Each Loan Party has all requisite power and authority to own and operate its
properties, to carry on its business as now conducted and as proposed to be
conducted, to enter into the Loan Documents to which it is a party and to carry
out the transactions contemplated thereby.

            B. QUALIFICATION AND GOOD STANDING. Each Loan Party is qualified to
do business and in good standing in every jurisdiction where its assets are
located and wherever necessary to carry out its business and operations, except
in jurisdictions where the failure to be so qualified or in good standing has
not had and could not reasonably be expected to result in a Material Adverse
Effect.

            C. CONDUCT OF BUSINESS. Holdings and its Subsidiaries are engaged
only in the businesses permitted to be engaged in pursuant to subsection 7.11.

            D. SUBSIDIARIES. All of the Subsidiaries of Holdings and their
jurisdictions of organization are identified in Schedule 5.1 annexed hereto, as
said Schedule 5.1 may be supplemented from time to time pursuant to the
provisions of subsection 6.1(xv). The Capital Stock of each of the Subsidiaries
of Holdings identified in Schedule 5.1 annexed hereto (as so supplemented) is
duly authorized, validly issued, fully paid and nonassessable and none of such
Capital Stock constitutes Margin Stock. Each of the Subsidiaries of Holdings
identified in Schedule 5.1 annexed hereto (as so supplemented) is a corporation,
partnership, trust or limited liability company duly organized, validly existing
and in good standing under the laws of its respective jurisdiction of
organization set forth therein, has all requisite power and authority to own and
operate its properties and to carry on its business as now conducted and as
proposed to be conducted, and is qualified to do business and in good standing
in every jurisdiction where its

                                       69

<PAGE>

assets are located and wherever necessary to carry out its business and
operations, in each case except where failure to be so qualified or in good
standing or a lack of such power and authority has not had and could not
reasonably be expected to result in a Material Adverse Effect. Schedule 5.1
annexed hereto (as so supplemented) correctly sets forth the ownership interest
of Holdings and each of its Subsidiaries in each of the Subsidiaries of Holdings
identified therein.

      5.2   AUTHORIZATION OF BORROWING, ETC.

            A. AUTHORIZATION OF BORROWING. The execution, delivery and
performance of the Loan Documents have been duly authorized by all necessary
action on the part of each Loan Party that is a party thereto.

            B. NO CONFLICT. The execution, delivery and performance by Loan
Parties of the Loan Documents to which they are parties and the consummation of
the transactions contemplated by the Loan Documents do not and will not (i)
violate any provision of any law or any governmental rule or regulation
applicable to Holdings or any of its Subsidiaries which violation could
reasonably be expected to have a Material Adverse Effect, or violate any
provision of the Organizational Documents of Holdings or any of its Subsidiaries
or any order, judgment or decree of any court or other Government Authority
binding on Holdings or any of its Subsidiaries, (ii) except as set forth in
Schedule 5.2 annexed hereto, conflict with, result in a breach of or constitute
(with due notice or lapse of time or both) a default under any Contractual
Obligation of Holdings or any of its Subsidiaries, (iii) result in or require
the creation or imposition of any Lien upon any of the properties or assets of
Holdings or any of its Subsidiaries (other than any Liens created under any of
the Loan Documents in favor of Administrative Agent on behalf of Lenders), or
(iv) require any approval of stockholders or any approval or consent of any
Person under any Contractual Obligation of Holdings or any of its Subsidiaries,
except for such approvals or consents which will be obtained on or before the
Closing Date and disclosed in writing to Lenders.

            C. GOVERNMENTAL CONSENTS. The execution, delivery and performance by
Loan Parties of the Loan Documents to which they are parties and the
consummation of the transactions contemplated by the Loan Documents do not and
will not require any Governmental Authorization.

            D. BINDING OBLIGATION. Each of the Loan Documents has been duly
executed and delivered by each Loan Party that is a party thereto and is the
legally valid and binding obligation of such Loan Party, enforceable against
such Loan Party in accordance with its respective terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or limiting creditors' rights generally or by equitable principles
relating to enforceability.

      5.3   FINANCIAL CONDITION.

            Company has heretofore delivered to Lenders, at Lenders' request,
the financial statements and information set forth in subsection 4.1D. All such
statements other than pro forma financial statements were prepared in conformity
with GAAP and fairly present, in all material respects, the financial position
(on a consolidated and, where applicable, consolidating

                                       70

<PAGE>

basis) of the entities described in such financial statements as at the
respective dates thereof and the results of operations and cash flows (on a
consolidated and, where applicable, consolidating basis) of the entities
described therein for each of the periods then ended, subject, in the case of
any such unaudited financial statements, to changes resulting from audit and
normal year-end adjustments. Neither Holdings nor any of its Subsidiaries has
(and will not have following the funding of the initial Loans) any Contingent
Obligation, contingent liability or liability for taxes, long-term lease or
unusual forward or long-term commitment that, as of the Closing Date, is not
reflected in the foregoing financial statements or the notes thereto and, as of
any Funding Date subsequent to the Closing Date, is not reflected in the most
recent financial statements delivered to Lenders pursuant to subsection 6.1 or
the notes thereto and that, in any such case, is material in relation to the
business, operations, properties, assets, condition (financial or otherwise) or
prospects of Company or any of its Subsidiaries.

      5.4   NO MATERIAL ADVERSE CHANGE; NO RESTRICTED JUNIOR PAYMENTS.

            Since December 31, 2002, no event or change has occurred that has
resulted in or evidences, either in any case or in the aggregate, a Material
Adverse Effect. Neither Holdings nor any of its Subsidiaries has directly or
indirectly declared, ordered, paid or made, or set apart any sum or property
for, any Restricted Junior Payment or agreed to do so except as permitted on the
Closing Date or by subsection 7.5.

      5.5   TITLE TO PROPERTIES; LIENS; REAL PROPERTY; INTELLECTUAL PROPERTY.

            A. TITLE TO PROPERTIES; LIENS. Holdings and its Subsidiaries have
(i) good, sufficient and legal title to (in the case of fee interests in real
property), (ii) valid leasehold interests in (in the case of leasehold interests
in real or personal property), or (iii) good title to (in the case of all other
personal property), all of their respective properties and assets reflected in
the financial statements referred to in subsection 5.3 or in the most recent
financial statements delivered pursuant to subsection 6.1, in each case except
for assets disposed of since the date of such financial statements in the
ordinary course of business or as otherwise permitted under subsection 7.7.
Except as permitted by this Agreement, all such properties and assets are free
and clear of Liens.

            B. REAL PROPERTY. As of the Closing Date, Schedule 5.5B annexed
hereto contains a true, accurate and complete list of (i) all fee interests in
any Real Property Assets and (ii) all leases, subleases or assignments of leases
(together with all amendments, modifications, supplements, renewals or
extensions of any thereof) affecting each Real Property Asset, regardless of
whether a Loan Party is the landlord or tenant (whether directly or as an
assignee or successor in interest) under such lease, sublease or assignment.
Except as specified in Schedule 5.5B annexed hereto, each agreement listed in
clause (ii) of the immediately preceding sentence is in full force and effect
and Company does not have knowledge of any default that has occurred and is
continuing thereunder that could reasonably be expected to result in a Material
Adverse Effect, and each such agreement constitutes the legally valid and
binding obligation of each applicable Loan Party, enforceable against such Loan
Party in accordance with its terms, except as enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
or limiting creditors' rights generally or by equitable principles.

                                       71

<PAGE>

            C. INTELLECTUAL PROPERTY. As of the Closing Date, Holdings and its
Subsidiaries own or have the right to use, all Intellectual Property used in the
conduct of their business, except where the failure to own or have such right to
use in the aggregate could not reasonably be expected to result in a Material
Adverse Effect. No claim has been asserted and is pending by any Person
challenging or questioning the use of any such Intellectual Property or the
validity or effectiveness of any such Intellectual Property, nor does Holdings
or any of its Subsidiaries know of any valid basis for any such claim except for
such claims that in the aggregate could not reasonably be expected to result in
a Material Adverse Effect. The use of such Intellectual Property by Holdings and
its Subsidiaries does not infringe on the rights of any Person, except for such
claims and infringements that, in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. All federal and state and all
foreign registrations of and applications for Intellectual Property, and all
unregistered Intellectual Property, that are owned or licensed by Holdings or
any of its Subsidiaries on the Closing Date are described on Schedule 5.5C
annexed hereto.

      5.6   LITIGATION; ADVERSE FACTS.

            Except as set forth in Schedule 5.6 annexed hereto, there are no
Proceedings (whether or not purportedly on behalf of Holdings or any of its
Subsidiaries) at law or in equity, or before or by any court or other Government
Authority (including any Environmental Claims) that are pending or, to the
knowledge of Holdings, threatened against or affecting Company or any of its
Subsidiaries or any property of Company or any of its Subsidiaries and that,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect. Neither Company nor any of its Subsidiaries (i) is in
violation of any applicable laws (including Environmental Laws) that,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect, or (ii) is subject to or in default with respect to any
final judgments, writs, injunctions, decrees, rules or regulations of any court
or other Government Authority, that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect.

      5.7   PAYMENT OF TAXES.

            Except to the extent permitted by subsection 6.3, all federal,
foreign and other material tax returns and reports of Holdings and its
Subsidiaries required to be filed by any of them have been timely filed, and all
taxes shown on such tax returns to be due and payable and all assessments, fees
and other governmental charges upon Holdings and its Subsidiaries and upon their
respective properties, assets, income, businesses and franchises that are due
and payable have been paid when due and payable. Company knows of no proposed
tax assessment against Holdings or any of its Subsidiaries that is not being
actively contested by Holdings or such Subsidiary in good faith and by
appropriate proceedings; provided that such reserves or other appropriate
provisions, if any, as shall be required in conformity with GAAP shall have been
made or provided therefor.

      5.8   PERFORMANCE OF AGREEMENTS; MATERIALLY ADVERSE AGREEMENTS; MATERIAL
            CONTRACTS.

performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in any of its Contractual Obligations, and no condition
exists that, with the giving of notice or the lapse of time or both, would
constitute such a default, except where the consequences, direct or indirect, of
such default or defaults, if any, could not reasonably be expected to result in
a Material Adverse Effect.

            B. Neither Holdings nor any of its Subsidiaries is a party to or
otherwise subject to any agreements or instruments or any charter or other
internal restrictions which, individually or in the aggregate, could reasonably
be expected to result in a Material Adverse Effect.

            C. Schedule 5.8 contains a true, correct and complete list of all
the Material Contracts in effect on the Closing Date. Except as described on
Schedule 5.8, as of the Closing Date all such Material Contracts are in full
force and effect and no material defaults currently exist thereunder.

      5.9   GOVERNMENTAL REGULATION.

            Neither Holdings nor any of its Subsidiaries is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940 or
under any other federal or state statute or regulation which may limit its
ability to incur Indebtedness or which may otherwise render all or any portion
of the Obligations unenforceable.

      5.10  SECURITIES ACTIVITIES.

            A. Neither Holdings nor any of its Subsidiaries is engaged
principally, or as one of its important activities, in the business of extending

25% of the value of the assets (either of Company only or of Company and its
Subsidiaries on a consolidated basis) subject to the provisions of subsection
7.2 or 7.7 or subject to any restriction contained in any agreement or
instrument, between Company and any Lender or any Affiliate of any Lender,
relating to Indebtedness and within the scope of subsection 8.2, will be Margin
Stock.

            A. Holdings, each of its Subsidiaries and each of their respective
ERISA Affiliates are in material compliance with all applicable provisions and
requirements of ERISA and the regulations and published interpretations
thereunder with respect to each Employee Benefit Plan, and have performed all
their material obligations under each Employee Benefit Plan. Each Employee
Benefit Plan that is intended to qualify under Section 401(a) of the Internal
Revenue Code is so qualified. Each Foreign Pension Plan has been maintained in
substantial compliance with its terms and with the requirements of any and all
applicable laws, statutes, rules, regulations and orders and has been
maintained, where required, in good standing

                                       73

<PAGE>

with applicable regulatory authorities. All contributions required to be made

            B. No ERISA Event has occurred or is reasonably expected to occur.

            C. Except to the extent required under Section 4980B of the Internal

annexed hereto, no Employee Benefit Plan provides health or welfare benefits
(through the purchase of insurance or otherwise) for any retired or former
employee of Holdings, any of its Subsidiaries or any of their respective ERISA
Affiliates.

            D. As of the most recent valuation date for any Pension Plan, the
amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of
ERISA), individually or in the aggregate for all Pension Plans (excluding for
purposes of such computation any Pension Plans with respect to which assets
exceed benefit liabilities), does not exceed $500,000.

            E. As of the most recent valuation date for each Multiemployer Plan
for which the actuarial report is available, the potential liability of
Holdings, its Subsidiaries and their respective ERISA Affiliates for a complete
withdrawal from such Multiemployer Plan (within the meaning of Section 4203 of
ERISA), when aggregated with such potential liability for a complete withdrawal
from all Multiemployer Plans, based on information available pursuant to Section
4221(e) of ERISA, does not exceed $500,000.

            F. The present value of the accrued benefit liabilities (whether or
not vested) under each Foreign Pension Plan which is funded, determined as of
the end of the most recently ended fiscal year of each such Foreign Pension Plan
on the basis of actuarial assumptions, each of which is reasonable, did not
exceed the fair market value of the assets of such Foreign Pension Plan by more
than $500,000, and for each Foreign Pension Plan which is not funded, the
obligations of such Foreign Pension Plan are properly accrued on the financial
statements of the Company or the applicable Subsidiary.

indemnifies Lenders against, and agrees that it will hold Lenders harmless from,
any claim, demand or liability for any such broker's or finder's fees alleged to

      order, consent decree or settlement agreement with any Person relating to
      (a) any Environmental Law, (b) any

            (iii) there are and, to Company's knowledge, have been no

      Effect;

            (v) compliance with all current or reasonably foreseeable future
      requirements pursuant to or under Environmental Laws would not,
      individually or in the aggregate, be reasonably expected to result in a
      Material Adverse Effect.

      5.14  EMPLOYEE MATTERS.

            There is no strike or work stoppage in existence or threatened
involving Holdings or any of its Subsidiaries that could reasonably be expected
to result in a Material Adverse Effect.

            B. GOVERNMENTAL AUTHORIZATIONS. No authorization, approval or other
action by, and no notice to or filing with, any Government Authority is required
for either (i) the pledge or grant by any Loan Party of the Liens purported to
be created in favor of Administrative Agent pursuant to any of the Collateral
Documents or (ii) the exercise by Administrative Agent of any rights or remedies
in respect of any Collateral (whether specifically granted or created pursuant

Administrative Agent by or on behalf of any Loan Party with respect to any of
the Collateral (in each case taken as a whole with respect to any particular
Collateral) is accurate and complete in all material respects.

      5.17  DISCLOSURE.

            No representation or warranty of Holdings or any of its Subsidiaries
contained in any Loan Document or in any other document, certificate or written
statement furnished to Lenders by or on behalf of Holdings or any of its
Subsidiaries for use in connection with the transactions contemplated by this
Agreement contains any untrue statement of a material fact or omits to state a
material fact (known to any Loan Party, in the case of any document not
furnished by it) necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances in which the same were
made. Any projections and pro forma financial information contained in such
materials are based upon good faith estimates and assumptions believed by each
Loan Party to be reasonable at the time made, it being recognized by Lenders
that such projections as to future events are not to be viewed as facts and that
actual results during the period or periods covered by any such projections may
differ from the projected results. There are no facts known (or which should
upon the reasonable exercise of diligence be known) to any Loan Party (other
than matters of a general economic nature) that, individually or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect
and that have not been disclosed herein or in such other documents, certificates
and statements furnished to Lenders for use in connection with the transactions
contemplated hereby.

faith, but are unable, to obtain such senior lienholder's consent (any such
non-excluded Real Property Asset described in the foregoing clause (i) or (ii)
being a "MORTGAGED PROPERTY"), Company or such Subsidiary Guarantor shall
deliver to Administrative Agent, as soon as practicable after such Person
acquires such Mortgaged Property or becomes a Subsidiary Guarantor, as the case
may be, a fully executed and notarized Mortgage, in proper form for recording in
all appropriate places in all applicable jurisdictions, encumbering the interest
of such Loan Party in such Mortgaged Property; and such opinions, appraisal,

Company shall maintain in effect one or more Interest Rate Agreements with
respect to the Term Loans, in an aggregate notional principal amount of not less

      6.11  DEPOSIT ACCOUNTS AND CASH MANAGEMENT SYSTEMS.

            Company shall, and shall cause each of its Domestic Subsidiaries to,

reasonably satisfactory to Administrative Agent. From and after the date that is
90 days after the Closing Date, Company shall not permit such Deposit Accounts

respect to any amounts in excess of $250,000. Company shall not, and shall not
permit any of its Domestic Subsidiaries to, accumulate amounts in Deposit

      Administrative Agent may deem necessary or advisable to perfect or
      otherwise protect such Liens; provided, however, that no action shall be
      required to be taken by any Loan Party with respect to the Capital Stock
      of any Foreign Subsidiary pursuant to this subsection in the event that
      Company and Administrative Agent agree in good faith that the pledge of
      such Capital Stock would result in an unreasonable tax liability to any

Subsidiaries shall create or assume any Lien upon any of its properties or
assets, whether now owned or hereafter acquired, other than Liens excepted by

Capital Stock owned by Holdings or any other Subsidiary of Holdings, (ii) repay

under all Letters of Credit then outstanding (whether or not any beneficiary
under any such Letter of Credit shall have presented, or shall be entitled at
such time to present, the drafts or other documents or certificates required to

and the same shall forthwith become, immediately due and payable, and the
obligation of each Lender to make any Loan, the obligation of Administrative

foregoing shall not affect in any way the obligations of Revolving Lenders under

            Notwithstanding anything contained in the second preceding
paragraph, if at any time within 60 days after an acceleration of the Loans
pursuant to clause (ii) of such paragraph Company shall pay all arrears of
interest and all payments on account of principal which shall have become due
otherwise than as a result of such acceleration (with interest on principal and,
to the extent permitted by law, on overdue interest, at the rates specified in
this Agreement) and all Events of Default and Potential Events of Default (other
than non-payment of the principal of and accrued interest on the Loans, in each
case which is due and payable solely by virtue of acceleration) shall be
remedied or waived pursuant to subsection 10.6, then Requisite Lenders, by
written notice to Company, may at their option rescind and annul such
acceleration and its consequences; but such action shall not affect any other or
subsequent Event of Default or Potential Event of Default or impair any right
consequent thereon. The provisions of this paragraph are intended merely to bind
Lenders to a decision which may be made at the election of Requisite Lenders and
are not intended, directly or indirectly, to benefit Company, and such
provisions shall not at any time be construed so as to grant Company the right
to require Lenders to rescind or annul any acceleration hereunder or to preclude
Administrative Agent or Lenders from exercising any of the rights or remedies
available to them under any of the Loan Documents, even if the conditions set
forth in this paragraph are met.

SECTION 9. ADMINISTRATIVE AGENT

      9.1   APPOINTMENT.

            A. APPOINTMENT OF ADMINISTRATIVE AGENT. Wells Fargo is hereby
appointed Administrative Agent hereunder and under the other Loan Documents.
Each Lender hereby authorizes Administrative Agent to act as its agent in
accordance with the terms of this Agreement and the other Loan Documents.
Administrative Agent agrees to act upon the express conditions contained in this
Agreement and the other Loan Documents, as applicable. The provisions of this
Section 9 are solely for the benefit of Administrative Agent and Lenders and no
Loan Party shall have rights as a third party beneficiary of any of the
provisions thereof. In performing its functions and duties under this Agreement,
Administrative Agent (other than as provided in subsection 2.1D) shall act
solely as an agent of Lenders and does not assume and shall not be deemed to
have assumed any obligation towards or relationship of agency or trust with or
for Company or any other Loan Party.

            B. APPOINTMENT OF SUPPLEMENTAL COLLATERAL AGENTS. It is the purpose
of this Agreement and the other Loan Documents that there shall be no violation
of any law of any jurisdiction denying or restricting the right of banking
corporations or associations to transact business as agent or trustee in such
jurisdiction. It is recognized that in case of litigation under this Agreement
or any of the other Loan Documents, and in particular in case of the enforcement
of any of the Loan Documents, or in case Administrative Agent deems that by
reason of any present or future law of any jurisdiction it may not exercise any
of the rights, powers or remedies granted herein or in any of the other Loan
Documents or take any other action which may be desirable or necessary in
connection therewith, it may be necessary that Administrative Agent appoint an
additional individual or institution as a separate trustee, co-trustee,
collateral agent or collateral co-agent (any such additional individual or
institution being referred to herein individually as a "SUPPLEMENTAL COLLATERAL
AGENT" and collectively as "SUPPLEMENTAL COLLATERAL AGENTS").

                                      104

<PAGE>

            In the event that Administrative Agent appoints a Supplemental
Collateral Agent with respect to any Collateral, (i) each and every right,
power, privilege or duty expressed or intended by this Agreement or any of the
other Loan Documents to be exercised by or vested in or conveyed to
Administrative Agent with respect to such Collateral shall be exercisable by and
vest in such Supplemental Collateral Agent to the extent, and only to the
extent, necessary to enable such Supplemental Collateral Agent to exercise such
rights, powers and privileges with respect to such Collateral and to perform
such duties with respect to such Collateral, and every covenant and obligation
contained in the Loan Documents and necessary to the exercise or performance
thereof by such Supplemental Collateral Agent shall run to and be enforceable by
either Administrative Agent or such Supplemental Collateral Agent, and (ii) the
provisions of this Section 9 and of subsections 10.2 and 10.3 that refer to
Administrative Agent shall inure to the benefit of such Supplemental Collateral
Agent and all references therein to Administrative Agent shall be deemed to be
references to Administrative Agent and/or such Supplemental Collateral Agent, as
the context may require.

            Should any instrument in writing from Company or any other Loan
Party be required by any Supplemental Collateral Agent so appointed by
Administrative Agent for more fully and certainly vesting in and confirming to
him or it such rights, powers, privileges and duties, Company shall, or shall
cause such Loan Party to, execute, acknowledge and deliver any and all such
instruments promptly upon request by Administrative Agent. In case any
Supplemental Collateral Agent, or a successor thereto, shall die, become
incapable of acting, resign or be removed, all the rights, powers, privileges
and duties of such Supplemental Collateral Agent, to the extent permitted by
law, shall vest in and be exercised by Administrative Agent until the
appointment of a new Supplemental Collateral Agent.

            C. CONTROL. Each Lender and Administrative Agent hereby appoint each
other Lender as agent for the purpose of perfecting Administrative Agent's
security interest in assets that, in accordance with the UCC, can be perfected
by possession or control.

      9.2   POWERS AND DUTIES; GENERAL IMMUNITY.

            A. POWERS; DUTIES SPECIFIED. Each Lender irrevocably authorizes
Administrative Agent to take such action on such Lender's behalf and to exercise
such powers, rights and remedies hereunder and under the other Loan Documents as
are specifically delegated or granted to Administrative Agent by the terms
hereof and thereof, together with such powers, rights and remedies as are
reasonably incidental thereto. Administrative Agent shall have only those duties
and responsibilities that are expressly specified in this Agreement and the
other Loan Documents. Administrative Agent may exercise such powers, rights and
remedies and perform such duties by or through its agents or employees.
Administrative Agent shall not have, by reason of this Agreement or any of the
other Loan Documents, a fiduciary relationship in respect of any Lender or
Company; and nothing in this Agreement or any of the other Loan Documents,
expressed or implied, is intended to or shall be so construed as to impose upon
Administrative Agent any obligations in respect of this Agreement or any of the
other Loan Documents except as expressly set forth herein or therein.

            B. NO RESPONSIBILITY FOR CERTAIN MATTERS. No Agent shall be
responsible to any Lender for the execution, effectiveness, genuineness,
validity, enforceability, collectibility

                                      105

<PAGE>

or sufficiency of this Agreement or any other Loan Document or for any
representations, warranties, recitals or statements made herein or therein or
made in any written or oral statements or in any financial or other statements,
instruments, reports or certificates or any other documents furnished or made by
such Agent to Lenders or by or on behalf of Company to such Agent or any Lender
in connection with the Loan Documents and the transactions contemplated thereby
or for the financial condition or business affairs of Company or any other
Person liable for the payment of any Obligations, nor shall such Agent be
required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained in any of
the Loan Documents or as to the use of the proceeds of the Loans or the use of
the Letters of Credit or as to the existence or possible existence of any Event
of Default or Potential Event of Default. Anything contained in this Agreement
to the contrary notwithstanding, Administrative Agent shall not have any
liability arising from confirmations of the amount of outstanding Loans or the
Letter of Credit Usage or the component amounts thereof.

            C. EXCULPATORY PROVISIONS. No Agent or any of its officers,
directors, employees or agents shall be liable to Lenders for any action taken
or omitted by such Agent under or in connection with any of the Loan Documents
except to the extent caused by such Agent's gross negligence or willful
misconduct. An Agent shall be entitled to refrain from any act or the taking of
any action (including the failure to take an action) in connection with this
Agreement or any of the other Loan Documents or from the exercise of any power,
discretion or authority vested in it hereunder or thereunder unless and until
such Agent shall have received instructions in respect thereof from Requisite
Lenders (or such other Lenders as may be required to give such instructions
under subsection 10.6) and, upon receipt of such instructions from Requisite
Lenders (or such other Lenders, as the case may be), such Agent shall be
entitled to act or (where so instructed) refrain from acting, or to exercise
such power, discretion or authority, in accordance with such instructions.
Without prejudice to the generality of the foregoing, (i) each Agent shall be
entitled to rely, and shall be fully protected in relying, upon any
communication, instrument or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and shall be
entitled to rely and shall be protected in relying on opinions and judgments of
attorneys (who may be attorneys for Company and its Subsidiaries), accountants,
experts and other professional advisors selected by it; and (ii) no Lender shall
have any right of action whatsoever against an Agent as a result of such Agent
acting or (where so instructed) refraining from acting under this Agreement or
any of the other Loan Documents in accordance with the instructions of Requisite
Lenders (or such other Lenders as may be required to give such instructions
under subsection 10.6).

            D. AGENTS ENTITLED TO ACT AS LENDER. The agency hereby created shall
in no way impair or affect any of the rights and powers of, or impose any duties
or obligations upon, an Agent in its individual capacity as a Lender hereunder.
With respect to its participation in the Loans and the Letters of Credit, an
Agent shall have the same rights and powers hereunder as any other Lender and
may exercise the same as though it were not performing the duties and functions
delegated to it hereunder, and the term "Lender" or "Lenders" or any similar
term shall, unless the context clearly otherwise indicates, include each Agent
in its individual capacity. An Agent and its Affiliates may accept deposits
from, lend money to, acquire equity interests in and generally engage in any
kind of commercial banking, investment banking, trust, financial advisory or
other business with Company or any of its Affiliates as if it were not

                                      106

<PAGE>

performing the duties specified herein, and may accept fees and other
consideration from Company for services in connection with this Agreement and
otherwise without having to account for the same to Lenders.

      9.3   INDEPENDENT INVESTIGATION BY LENDERS; NO RESPONSIBILITY FOR
            APPRAISAL OF CREDITWORTHINESS.

            Each Lender agrees that it has made its own independent
investigation of the financial condition and affairs of Company and its
Subsidiaries in connection with the making of the Loans and the issuance of
Letters of Credit hereunder and that it has made and shall continue to make its
own appraisal of the creditworthiness of Company and its Subsidiaries. No Agent
shall have any duty or responsibility, either initially or on a continuing
basis, to make any such investigation or any such appraisal on behalf of Lenders
or to provide any Lender with any credit or other information with respect
thereto, whether coming into its possession before the making of the Loans or at
any time or times thereafter, and no Agent shall have any responsibility with
respect to the accuracy of or the completeness of any information provided to
Lenders.

      9.4   RIGHT TO INDEMNITY.

            Each Lender, in proportion to its Pro Rata Share, severally agrees
to indemnify Agents and the officers, directors, employees, agents, attorneys,
professional advisors and affiliates of each of them to the extent that any such
Person shall not have been reimbursed by Company, for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including counsel fees and disbursements and fees and
disbursements of any financial advisor engaged by Agents) or disbursements of
any kind or nature whatsoever which may be imposed on, incurred by or asserted
against an Agent or and other such Persons in exercising the powers, rights and
remedies of an Agent or performing duties of an Agent hereunder or under the
other Loan Documents or otherwise in its capacity as Agent in any way relating
to or arising out of this Agreement or the other Loan Documents; provided that
no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from an Agent's gross negligence or willful misconduct
as determined by a final judgment of a court of competent jurisdiction. If any
indemnity furnished to an Agent or any other such Person for any purpose shall,
in the opinion of such Agent, be insufficient or become impaired, such Agent may
call for additional indemnity and cease, or not commence, to do the acts
indemnified against until such additional indemnity is furnished.

      9.5   SUCCESSOR ADMINISTRATIVE AGENT AND SWING LINE LENDER.

            A. SUCCESSOR ADMINISTRATIVE AGENT. Any Agent may resign at any time
by giving 30 days' prior written notice thereof to Lenders and Company, and
Administrative Agent may be removed at any time with or without cause by an
instrument or concurrent instruments in writing delivered to Company and
Administrative Agent and signed by Requisite Lenders. Upon any such notice of
resignation or any such removal, Requisite Lenders shall have the right, upon
five Business Days' notice to Company, to appoint a successor Administrative
Agent. Upon the acceptance of any appointment as Administrative Agent hereunder
by a successor Administrative Agent, that successor Administrative Agent shall
thereupon succeed to and become vested with

                                      107

<PAGE>

all the rights, powers, privileges and duties of the retiring or removed
Administrative Agent and the retiring or removed Administrative Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring or removed Agent's resignation or removal hereunder as an Agent, the
provisions of this Section 9 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was an Agent under this Agreement.

            B. SUCCESSOR SWING LINE LENDER. Any resignation or removal of
Administrative Agent pursuant to subsection 9.5A shall also constitute the
resignation or removal of Wells Fargo or its successor as Swing Line Lender, and
any successor Administrative Agent appointed pursuant to subsection 9.5A shall,
upon its acceptance of such appointment, become the successor Swing Line Lender
for all purposes hereunder. In such event (i) Company shall prepay any
outstanding Swing Line Loans made by the retiring or removed Administrative
Agent in its capacity as Swing Line Lender, (ii) upon such prepayment, the
retiring or removed Administrative Agent and Swing Line Lender shall surrender
any Swing Line Note held by it to Company for cancellation, and (iii) if so
requested by the successor Administrative Agent and Swing Line Lender in
accordance with subsection 2.1E, Company shall issue a new Swing Line Note to
the successor Administrative Agent and Swing Line Lender substantially in the
form of Exhibit VII annexed hereto, in the principal amount of the Swing Line
Loan Commitment then in effect and with other appropriate insertions.

      9.6   COLLATERAL DOCUMENTS AND GUARANTIES.

            Each Lender hereby further authorizes Administrative Agent, on
behalf of and for the benefit of Lenders, to enter into each Collateral Document
as secured party and to be the agent for and representative of Lenders under
each Guaranty, and each Lender agrees to be bound by the terms of each
Collateral Document and Guaranty; provided that Administrative Agent shall not
(i) enter into or consent to any material amendment, modification, termination
or waiver of any provision contained in any Collateral Document or Guaranty or
(ii) release any Collateral (except as otherwise expressly permitted or required
pursuant to the terms of this Agreement or the applicable Collateral Document),
in each case without the prior consent of Requisite Lenders (or, if required
pursuant to subsection 10.6, all Lenders); provided further, however, that,
without further written consent or authorization from Lenders, Administrative
Agent may execute any documents or instruments necessary to (a) release any Lien
encumbering any item of Collateral that is the subject of a sale or other
disposition of assets permitted by this Agreement or to which Requisite Lenders
have otherwise consented, (b) release any Subsidiary Guarantor from the
Subsidiary Guaranty if all of the Capital Stock of such Subsidiary Guarantor is
sold to any Person (other than an Affiliate of Company) pursuant to a sale or
other disposition permitted hereunder or to which Requisite Lenders have
otherwise consented or (c) subordinate the Liens of Administrative Agent, on
behalf of Lenders, to any Liens permitted by subsection 7.2; provided that, in
the case of a sale of such item of Collateral or stock referred to in
subdivision (a) or (b), the requirements of subsection 10.14 are satisfied.
Anything contained in any of the Loan Documents to the contrary notwithstanding,
Company, Administrative Agent and each Lender hereby agree that (1) no Lender
shall have any right individually to realize upon any of the Collateral under
any Collateral Document or to enforce any Guaranty, it being understood and
agreed that all powers, rights and remedies under the Collateral Documents and
the Guaranties may be exercised solely by Administrative Agent for the benefit
of Lenders in accordance with the terms thereof, and (2) in the event of a
foreclosure by Administrative Agent

                                      108

<PAGE>

on any of the Collateral pursuant to a public or private sale, Administrative
Agent or any Lender may be the purchaser of any or all of such Collateral at any
such sale and Administrative Agent, as agent for and representative of Lenders
(but not any Lender or Lenders in its or their respective individual capacities
unless Requisite Lenders shall otherwise agree in writing) shall be entitled,
for the purpose of bidding and making settlement or payment of the purchase
price for all or any portion of the Collateral sold at any such public sale, to
use and apply any of the Obligations as a credit on account of the purchase
price for any collateral payable by Administrative Agent at such sale.

            Without derogating from or limiting any other authority granted to
Administrative Agent herein or in any other Loan Document, each Lender hereby
specifically (i) authorizes Administrative Agent to enter into the Foreign
Pledge Agreements, including, without limitation, such Foreign Pledge Agreements
governed by the laws of Canada, France, Germany, Spain and the United Kingdom
respectively, as agent on behalf of Lenders, with the effect that Lenders each
become a secured party thereunder, (ii) appoints Administrative Agent as its
attorney-in-fact granting it the powers to execute and register, as applicable,
each such Foreign Pledge Agreement or any other document, instrument or
agreement related to perfection, enforceability or notice of the security
interests of Lenders in any of the Collateral in its name and on its behalf,

co-agent, documentation agent or syndication agent, such Lender shall not have

Obligations or the rights of any Lenders or to authorize Administrative Agent to
vote in respect of the claim of any Lender in any such proceeding.

permitted hereby and, to the extent expressly contemplated hereby, the
Affiliates of each of Administrative Agent and Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

            B. ASSIGNMENTS.

            (i) Amounts and Terms of Assignments. Any Lender may assign to one
      or more Eligible Assignees all or any portion of its rights and
      obligations under this Agreement; provided that (a), except (1) in the
      case of an assignment of the entire remaining amount of the assigning
      Lender's rights and obligations under this Agreement or (2) in the case of
      an assignment to a Lender or an Affiliate of a Lender or an Approved Fund
      of a Lender, the aggregate amount of the Revolving Loan Exposure, Tranche
      A Term Loan Exposure or Tranche B Term Loan Exposure, as the case may be,
      of the assigning Lender and the assignee subject to each such assignment
      shall not be less than $3,000,000, in the case of any assignment of a
      Revolving Loan, or $3,000,000, in the case of any assignment of a Term
      Loan, unless each of Administrative Agent and, so long as no Event of
      Default has occurred and is continuing, Company otherwise consents each
      such consent not to be unreasonably withheld or delayed), (b) each partial
      assignment shall be made as an assignment of a proportionate part of all
      the assigning Lender's rights and obligations under this Agreement with
      respect to the Loan or the Commitment assigned, (c) the parties to each
      assignment shall execute and deliver to Administrative Agent an Assignment
      Agreement, together with a processing and recordation fee of $3500 (unless
      the assignee is an Affiliate or an Approved Fund of the assignor, in which
      case no fee shall be required), and the Eligible Assignee, if it shall not
      be a Lender, shall deliver to Administrative Agent information reasonably
      requested by Administrative Agent, including such forms, certificates or
      other evidence, if any, with respect to United States federal income tax
      withholding matters as the assignee under such Assignment Agreement may be
      required to deliver to Administrative Agent pursuant to subsection
      2.7B(iii) and (d), except in the case of an assignment to another Lender,
      an Affiliate of a Lender or an Approved Fund of a Lender, Administrative
      Agent and, if no Event of Default has occurred and is continuing, Company,
      shall have consented thereto (which consent shall not be unreasonably
      withheld. Upon such execution, delivery and consent, from and after the
      effective date specified in such Assignment Agreement, (y) the assignee
      thereunder shall be a party hereto and, to the extent that rights and
      obligations hereunder have been assigned to it pursuant to such Assignment
      Agreement, shall have the rights and obligations of a Lender hereunder and
      (z) the assigning Lender thereunder shall, to the extent that rights and
      obligations hereunder have been assigned by it pursuant to such Assignment
      Agreement, relinquish its rights (other than any rights which survive the
      termination of this Agreement under subsection 10.9B) and be released from
      its obligations under this Agreement (and, in the case of an Assignment
      Agreement covering all or the remaining portion of an assigning Lender's
      rights and obligations under this Agreement, such Lender shall cease to be
      a party hereto; provided that, anything contained in any of the Loan
      Documents to the contrary notwithstanding, if such

                                      111

<PAGE>

      Lender is the Issuing Lender with respect to any outstanding Letters of
      Credit such Lender shall continue to have all rights and obligations of an
      Issuing Lender with respect to such Letters of Credit until the
      cancellation or expiration of such Letters of Credit and the reimbursement
      of any amounts drawn thereunder). The assigning Lender shall, upon the
      effectiveness of such assignment or as promptly thereafter as practicable,
      surrender its Notes, if any, to Administrative Agent for cancellation, and
      thereupon new Notes shall, if so requested by the assignee and/or the
      assigning Lender in accordance with subsection 2.1E, be issued to the
      assignee and/or to the assigning Lender, substantially in the form of
      Exhibit IV, Exhibit V or Exhibit VI annexed hereto, as the case may be,
      with appropriate insertions, to reflect the new Commitments and/or
      outstanding Revolving Loans and/or outstanding Tranche A Term Loans and/or
      Tranche B Term Loans, as the case may be, of the assignee and/or the
      assigning Lender. Other than as provided in subsection 2.1A(iv) and
      subsection 10.5, any assignment or transfer by a Lender of rights or
      obligations under this Agreement that does not comply with this subsection
      10.1B shall be treated for purposes of this Agreement as a sale by such
      Lender of a participation in such rights and obligations in accordance
      with subsection 10.1C.

            (ii) Acceptance by Administrative Agent; Recordation in Register.
      Upon its receipt of an Assignment Agreement executed by an assigning
      Lender and an assignee representing that it is an Eligible Assignee,
      together with the processing and recordation fee referred to in subsection
      10.1B(i) and any forms, certificates or other evidence with respect to
      United States federal income tax withholding matters that such assignee
      may be required to deliver to Administrative Agent pursuant to subsection
      2.7B(iii), Administrative Agent shall, if Administrative Agent and Company
      have consented to the assignment evidenced thereby (in each case to the
      extent such consent is required pursuant to subsection 10.1B(i)), (a)
      accept such Assignment Agreement by executing a counterpart thereof as
      provided therein (which acceptance shall evidence any required consent of
      Administrative Agent to such assignment), (b) record the information
      contained therein in the Register, and (c) give prompt notice thereof to
      Company. Administrative Agent shall maintain a copy of each Assignment
      Agreement delivered to and accepted by it as provided in this subsection
      10.1B(ii).

            (iii) If the consent of Company to an assignment or to an Eligible
      Assignee is required hereunder (including a consent to an assignment which
      does not meet the minimum assignment thresholds specified in subsection
      10.1B(i)), Company shall be deemed to have given its consent five Business
      Days after the date notice thereof has been delivered by the assigning
      Lender (through Administrative Agent) unless such consent is expressly
      refused by Company prior to such fifth Business Day.

            C. PARTICIPATIONS. Any Lender may, without the consent of, or notice
to, Company or Administrative Agent, sell participations to one or more banks or
other entities that is not a Competitor in all or a portion of such Lender's
rights and/or obligations under this Agreement; provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) Company, Administrative Agent and Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender

                                      112

<PAGE>

sells such a participation shall provide that such Lender 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 Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver directly affecting
(i) the extension of the scheduled final maturity date of any Loan allocated to
such participation or (ii) a reduction of the principal amount of or the rate of
interest payable on any Loan allocated to such participation. Subject to the
further provisions of this subsection 10.1C, Company agrees that each
Participant shall be entitled to the benefits, and subject to the requirements,
of subsections 2.6D and 2.7 (including without limitation the requirements of
subsection 2.7B(iii)(a)) to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to subsection 10.1B. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
subsection 10.4 as though it were a Lender, provided such Participant agrees to
be subject to subsection 10.5 as though it were a Lender. A Participant shall
not be entitled to receive any greater payment under subsections 2.6D and 2.7
than the applicable Lender would have been entitled to receive with respect to
the participation sold to such Participant unless the sale of the participation
to such Participant is made with Company's prior written consent.

            D. PLEDGES AND ASSIGNMENTS. Any Lender may at any time pledge or
assign a security interest in all or any portion of its Loans, and the other
Obligations owed to such Lender, to secure obligations of such Lender, including
without limitation any pledge or assignment to secure obligations to any Federal
Reserve Bank; provided that (i) no Lender shall be relieved of any of its
obligations hereunder as a result of any such assignment or pledge and (ii) in
no event shall any assignee or pledgee be considered to be a "Lender" or be
entitled to require the assigning Lender to take or omit to take any action
hereunder.

            E. INFORMATION. Each Lender may furnish any information concerning
Company and its Subsidiaries in the possession of that Lender from time to time
to assignees and participants (including prospective assignees and participants)
that is not a Competitor, subject to subsection 10.20.

            F. AGREEMENTS OF LENDERS. Each Lender listed on the signature pages
hereof hereby agrees, and each Lender that becomes a party hereto pursuant to an
Assignment Agreement shall be deemed to agree, (i) that it is an Eligible
Assignee described in clause (ii) of the definition thereof; (ii) that it has
experience and expertise in the making of or purchasing loans such as the Loans;
and (iii) that it will make or purchase Loans for its own account in the
ordinary course of its business and without a view to distribution of such Loans
within the meaning of the Securities Act or the Exchange Act or other federal
securities laws (it being understood that, subject to the provisions of this
subsection 10.1, the disposition of such Loans or any interests therein shall at
all times remain within its exclusive control).

            G. TRANSFERS OF BENEFICIAL INTERESTS. Any Person that acquires a
beneficial interest in any Loans other than in accordance with subsection 10.1B
or C shall not be entitled to the benefits of subsection 2.7.

whether or not the transactions contemplated hereby shall be consummated,
Company agrees to defend (subject to Indemnitees' selection of counsel),
indemnify, pay and hold harmless Agents and Lenders, and the officers,
directors, employees, agents and affiliates of Agents and Lenders (collectively
called the "INDEMNITEES"), from and against any and all Indemnified Liabilities
(as hereinafter defined); provided that Company shall not have any obligation to
any Indemnitee hereunder with respect to any Indemnified Liabilities to the
extent such Indemnified Liabilities arise solely from the gross negligence or
willful misconduct of that Indemnitee as determined by a final judgment of a
court of competent jurisdiction.

                                      114

or consequential and whether based on any federal, state or foreign laws,
statutes, rules or regulations (including securities and commercial laws,
statutes, rules or regulations and Environmental Laws), on common law or
equitable cause or on contract or otherwise, that may be imposed on, incurred
by, or asserted against any such Indemnitee, in any manner relating to or
arising out of (i) this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby (including Lenders' agreement to
make the Loans hereunder or the use or intended use of the proceeds thereof or

letter delivered by any Lender to Company with respect thereto, or (iii) any
Environmental Claim or any Hazardous Materials Activity relating to or arising
from, directly or indirectly, any past or present activity, operation, land
ownership, or practice of Company or any of its Subsidiaries.

            To the extent that the undertakings to defend, indemnify, pay and
hold harmless set forth in this subsection 10.3 may be unenforceable in whole or
in part because they are violative of any law or public policy, Company shall
contribute the maximum portion that it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all Indemnified Liabilities
incurred by Indemnitees or any of them.

      10.4  SET-OFF.

            In addition to any rights now or hereafter granted under applicable
law and not by way of limitation of any such rights, upon the occurrence of any
Event of Default each Lender is hereby authorized by Company at any time or from
time to time, without notice to Company or to any other Person, any such notice
being hereby expressly waived, to set off and to appropriate and to apply any
and all deposits (general or special, time or demand, provisional or final,
including Indebtedness evidenced by certificates of deposit, whether matured or
unmatured, but not including trust accounts) and any other Indebtedness at any
time held or owing by that Lender or any Affiliate of that Lender to or for the
credit or the account of Company and each other Loan Party against and on
account of the Obligations of Company or any other Loan Party to that Lender (or
any Affiliate of that Lender) or to any other Lender (or any Affiliate of any
other Lender) under this Agreement, the Letters of Credit and participations
therein and the other Loan Documents, including all claims of any nature or
description arising out of or connected with this Agreement, the Letters of
Credit and participations therein or any other Loan Document, irrespective of
whether or not (i) that Lender shall have made any demand hereunder or (ii) the
principal of or the interest on the Loans or any amounts in respect of the
Letters of

                                      115

<PAGE>

Credit or any other amounts due hereunder shall have become due and payable
pursuant to Section 8 and although said obligations and liabilities, or any of
them, may be contingent or unmatured.

      10.5  RATABLE SHARING.

            Lenders hereby agree among themselves that if any of them shall,
whether by voluntary or mandatory payment (other than a payment or prepayment of
Loans made and applied in accordance with the terms of this Agreement), by
realization upon security, through the exercise of any right of set-off or
banker's lien, by counterclaim or cross action or by the enforcement of any
right under the Loan Documents or otherwise, or as adequate protection of a
deposit treated as cash collateral under the Bankruptcy Code, receive payment or
reduction of a proportion of the aggregate amount of principal, interest,
amounts payable in respect of Letters of Credit, fees and other amounts then due
and owing to that Lender hereunder or under the other Loan Documents
(collectively, the "AGGREGATE AMOUNTS DUE" to such Lender) that is greater than
the proportion received by any other Lender in respect of the Aggregate Amounts
Due to such other Lender, then the Lender receiving such proportionately greater
payment shall, unless such proportionately greater payment is required by the
terms of this Agreement, (i) notify Administrative Agent and each other Lender
of the receipt of such payment and (ii) apply a portion of such payment to
purchase assignments (which it shall be deemed to have purchased from each
seller of an assignment simultaneously upon the receipt by such seller of its
portion of such payment) of the Aggregate Amounts Due to the other Lenders so
that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders
in proportion to the Aggregate Amounts Due to them; provided that if all or part
of such proportionately greater payment received by such purchasing Lender is
thereafter recovered from such Lender upon the bankruptcy or reorganization of
Company or otherwise, those purchases shall be rescinded and the purchase prices
paid for such assignments shall be returned to such purchasing Lender ratably to
the extent of such recovery, but without interest. Company expressly consents to
the foregoing arrangement and agrees that any purchaser of an assignment so
purchased may exercise any and all rights of a Lender as to such assignment as
fully as if that Lender had complied with the provisions of subsection 10.1B
with respect to such assignment. In order to further evidence such assignment
(and without prejudice to the effectiveness of the assignment provisions set
forth above), each purchasing Lender and each selling Lender agree to enter into
an Assignment Agreement at the request of a selling Lender or a purchasing
Lender, as the case may be, in form and substance reasonably satisfactory to
each such Lender.

      10.6  AMENDMENTS AND WAIVERS.

            No amendment, modification, termination or waiver of any provision
of this Agreement or of the Notes, and no consent to any departure by Company
therefrom, shall in any event be effective without the written concurrence of
Requisite Lenders; provided that no such amendment, modification, termination,

interest rate or fee is calculated that would result in a reduction of any such
rate or fee), (6) reduce the amount or postpone the due date of any amount
payable in respect of any Letter of Credit, (7) extend the expiration date of
any Letter of Credit beyond the Revolving Loan Commitment Termination Date or

prepayment, or Commitment reduction from those set forth in subsection 2.4 with
respect to one Class but not any other Class shall be deemed to
disproportionately disadvantage such one Class but not to disproportionately
disadvantage any such other Class for purposes of this clause (vi)) and (vii) no
Commitment of a Lender shall be increased without the consent of such Lender and
the consent of Supermajority Lenders. Administrative Agent may, but shall have
no obligation to, with the concurrence of any Lender, execute amendments,

                                      117

<PAGE>

modifications, waivers or consents on behalf of that Lender. Any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on Company in any case
shall entitle Company to any other or further notice or demand in similar or
other circumstances. Any amendment, modification, termination, waiver or consent
effected in accordance with this subsection 10.6 shall be binding upon each
Lender at the time outstanding, each future Lender and, if signed by Company, on
Company.

      10.7  INDEPENDENCE OF COVENANTS.

            All covenants hereunder shall be given independent effect so that if
a particular action or condition is not permitted by any of such covenants, the
fact that it would be permitted by an exception to, or would otherwise be within
the limitations of, another covenant shall not avoid the occurrence of an Event
of Default or Potential Event of Default if such action is taken or condition
exists.

      10.8  NOTICES; EFFECTIVENESS OF SIGNATURES.

            Unless otherwise specifically provided herein, any notice or other
communication herein required or permitted to be given shall be in writing and
may be personally served, or sent by telefacsimile or United States mail or
courier service and shall be deemed to have been given when delivered in person
or by courier service, upon receipt of telefacsimile in complete and legible
form, or three Business Days after depositing it in the United States mail with
postage prepaid and properly addressed; provided that notices to Administrative
Agent shall not be effective until received. For the purposes hereof, the
address of each party hereto shall be as set forth under such party's name on
the signature pages hereof or (i) as to Company and Administrative Agent, such
other address as shall be designated by such Person in a written notice
delivered to the other parties hereto and (ii) as to each other party, such
other address as shall be designated by such party in a written notice delivered
to Administrative Agent.

            Loan Documents and notices under the 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 an original copy with manual signatures and shall be binding on all Loan
Parties, Agents and Lenders. Administrative Agent may also require that any such
documents and signature be confirmed by a manually-signed copy thereof;
provided, however, that the failure to request or deliver any such
manually-signed copy shall not affect the effectiveness of any facsimile
document or signature.

      10.9  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

            A. All representations, warranties and agreements made herein shall
survive the execution and delivery of this Agreement and the making of the Loans
and the issuance of the Letters of Credit hereunder.

            B. Notwithstanding anything in this Agreement or implied by law to
the contrary, the agreements of Company set forth in subsections 2.6D, 2.7,
3.5A, 10.2, 10.3, 10.4, 10.18 and 10.19 and the agreements of Lenders set forth
in subsections 9.2C, 9.4, 10.5 and 10.19 shall survive the payment of the Loans,
the cancellation or expiration of the Letters of Credit and the reimbursement of
any amounts drawn thereunder, and the termination of this Agreement.

                                      118

      10.10 FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.

            No failure or delay on the part of an Agent or any Lender in the
exercise of any power, right or privilege hereunder or under any other Loan
Document shall impair such power, right or privilege or be construed to be a
waiver of any default or acquiescence therein, nor shall any single or partial
exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other power, right or privilege. All rights and
remedies existing under this Agreement and the other Loan Documents are
cumulative to, and not exclusive of, any rights or remedies otherwise available.

      10.11 MARSHALLING; PAYMENTS SET ASIDE.

            Neither any Agent nor any Lender shall be under any obligation to
marshal any assets in favor of Company or any other party or against or in
payment of any or all of the Obligations. To the extent that Company makes a
payment or payments to Administrative Agent or Lenders (or to Administrative
Agent for the benefit of Lenders), or Agents or Lenders enforce any security
interests or exercise their rights of setoff, and such payment or payments or
the proceeds of such enforcement or setoff or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, any other state or federal law, common law or any equitable
cause, then, to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied, and all Liens, rights and remedies therefor
or related thereto, shall be revived and continued in full force and effect as
if such payment or payments had not been made or such enforcement or setoff had
not occurred.

      10.12 SEVERABILITY.

            In case any provision in or obligation under this Agreement or the
Notes shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

      10.13 OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS.

            The obligations of Lenders hereunder are several and no Lender shall
be responsible for the obligations or Commitments of any other Lender hereunder.
Nothing contained herein or in any other Loan Document, and no action taken by
Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders, or
Lenders and Company, as a partnership, an association, a joint venture or any
other kind of entity. The amounts payable at any time hereunder to each Lender
shall be a separate and independent debt, and each Lender shall be entitled to
protect and enforce its rights arising out of this Agreement and it shall not be
necessary for any other Lender to be joined as an additional party in any
proceeding for such purpose.

      10.14 RELEASE OF SECURITY INTEREST OR GUARANTY.

            Upon the proposed sale or other disposition of any Collateral that
is permitted by this Agreement or to which Requisite Lenders have otherwise
consented, or the sale or other

                                      119

<PAGE>

disposition of all of the Capital Stock of a Subsidiary Guarantor to any Person
(other than an Affiliate of Company) permitted by this Agreement or to which
Requisite Lenders have otherwise consented, for which a Loan Party desires to
obtain a security interest release or a release of the Subsidiary Guaranty from
Administrative Agent, such Loan Party shall deliver an Officer's Certificate (i)
stating that the Collateral or the Capital Stock subject to such disposition is
being sold or otherwise disposed of in compliance with the terms hereof and (ii)
specifying the Collateral or Capital Stock being sold or otherwise disposed of
in the proposed transaction. Upon the receipt of such Officer's Certificate,
Administrative Agent shall, at such Loan Party's expense, so long as
Administrative Agent (a) has no reason to believe that the facts stated in such
Officer's Certificate are not true and correct and (b) if the sale or other
disposition of such item of Collateral or Capital Stock constitutes an Asset
Sale, shall have received evidence satisfactory to it that arrangements
satisfactory to it have been made for delivery of the Net Asset Sale Proceeds if
and as required by subsection 2.4, execute and deliver such releases of its
security interest in such Collateral or such Subsidiary Guaranty, as may be
reasonably requested by such Loan Party.

      10.15 HEADINGS.

solely that of debtor and creditor. Accordingly, each of the parties hereto
acknowledges and agrees that the terms of this Agreement shall not be construed
against or in favor of another party.

            (V) AGREES THAT LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN ANY
      OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST COMPANY IN
      THE COURTS OF ANY OTHER JURISDICTION; AND

            (VI) AGREES THAT THE PROVISIONS OF THIS SUBSECTION 10.18 RELATING TO
      JURISDICTION AND VENUE SHALL BE BINDING AND ENFORCEABLE TO THE FULLEST
      EXTENT PERMISSIBLE UNDER NEW YORK GENERAL OBLIGATIONS LAW SECTION 5-1402
      OR OTHERWISE.

      10.19 WAIVER OF JURY TRIAL.

            EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY DEALINGS
BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR THE

and that it knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel. THIS WAIVER

<PAGE>

10.19 AND EXECUTED BY EACH OF THE PARTIES HERETO), AND THIS WAIVER SHALL APPLY
TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY OTHER DOCUMENTS OR
AGREEMENTS RELATING TO THE LOANS MADE HEREUNDER. In the event of litigation,
this Agreement may be filed as a written consent to a trial by the court.

      10.20 CONFIDENTIALITY.

            Each Lender shall hold all non-public information obtained pursuant
to the requirements of this Agreement that has been identified in writing as
confidential by Company in accordance with such Lender's customary procedures
for handling confidential information of this nature and in accordance with safe
and sound banking practices, it being understood and agreed by Company that in
any event a Lender may make disclosures (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel

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 Government Authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party

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
Company, (g) with the consent of Company, (h) to the extent such information (i)
becomes publicly available other than as a result of a breach of this subsection
10.20 or (ii) becomes available to Administrative Agent or any Lender on a
nonconfidential basis from a source other than 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
Lender's or its Affiliates' investment portfolio in connection with ratings
issued with respect to such Lender or its Affiliates and that no written or oral
communications from counsel to an Agent and no information that is or is
designated as privileged or as attorney work product may be disclosed to any
Person unless such Person is a Lender or a participant hereunder; provided that,
unless specifically prohibited by applicable law or court order, each Lender
shall notify Company of any request by any Government Authority or
representative thereof (other than any such request in connection with any
examination of the financial condition of such Lender by such Government
Authority) for disclosure of any such non-public information prior to disclosure
of such information; and provided, further that in no event shall any Lender be
obligated or required to return any materials furnished by Company or any of its
Subsidiaries.

kind, any information with respect to United States federal income tax treatment

hereby and all materials of any kind (including opinions or other tax analyses)
that are provided to Administrative Agent or such Lender relating to such tax
treatment and tax structure.
