    Section 2.03.  Special Meetings.  Special meetings of the shareholders may be held at any time and
for any purpose and may be called by the Chief Executive Officer, the Chairman of the Board, the Chief Financial Officer, any two directors, or by a shareholder or shareholders holding ten percent
(10%) or more of the shares entitled to vote on the matters to be presented to the meeting, except that a special meeting of shareholders called for the purpose of considering any action to directly
or indirectly facilitate or effect a business combination (as defined by Minnesota Law), including any action to change or otherwise affect the composition of the Board of Directors for that purpose,
may not be called by less than twenty-five percent (25%) of the shares entitled to vote on the matters to be presented at the meeting. 

    Section 2.04.  Quorum, Adjourned Meetings.  The holder of a majority of the shares entitled to
vote shall constitute a quorum for the transaction of business at any regular or special meeting. In case a quorum shall not be present at a meeting, those present may adjourn the meeting to such day
as they shall, by majority vote, agree upon, and a notice of such adjournment and the date and time at which such meeting shall be reconvened shall be mailed to each shareholder entitled to vote at
least 5 days before such adjourned meeting. If a quorum is present, a meeting may be adjourned from time to time 

 

without notice other than announcement at the meeting. At adjourned meetings at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally
noticed. If a quorum is present, the shareholders may continue to transact business until adjournment notwithstanding the withdrawal of enough shareholders to leave less than a quorum. 

    Section 2.05.  Voting.  At each meeting of the shareholders, every shareholder having the right to
vote shall be entitled to vote either in person or by proxy. Each shareholder, unless the Articles of Incorporation or statute provide otherwise, shall have one vote for each share having voting power

Incorporation, or these Bylaws.

60 days preceding the date of any meeting of shareholders, as a record date for the determination of the shareholders entitled to notice of, and to vote at, such meeting, notwithstanding any
transfer of shares on the books of the corporation after any record date so fixed. The Board of Directors may close the books of the corporation against the transfer of shares during the whole or any
part of such period. 

    If
the Board of Directors fails to fix a record date for determination of the shareholders entitled to notice of, and to vote at, any meeting of shareholders, the record date shall be
the 20th day preceding the date of such meeting.

    Section 2.08.  Waiver of Notice.  Notice of any regular or special meeting may be waived by any
shareholder either before, at or after such meeting orally or in a writing signed by such shareholder or a representative entitled to vote the shares of such shareholder. A shareholder, by his
attendance at any meeting of shareholders, shall be deemed to have waived notice of such meeting, except where the shareholder objects at the beginning of the meeting to the transaction of business
because the item may
not lawfully be considered at that meeting and does not participate in the consideration of the item at that meeting. 

    Section 2.09.  Written Action.  Any action which might be taken at a meeting of the shareholders
may be taken without a meeting if done in writing and signed by all of the shareholders entitled to vote on that action.

notice of any proposal to be submitted at an annual meeting and such notice must be delivered to the Secretary of the corporation so as to be received at the principal executive offices of the
corporation not less than 120 days in advance of the date of the corporation's proxy statement released to shareholders in connection with the previous year's annual meeting of shareholders,
except that is no annual meeting was held in the previous year or the date of the annual meeting has been changed by

more than 30 days from the date contemplated at the time of the previous year's proxy statement, such notice must be so received a reasonable time before the solicitation is made. Each such
notice shall set forth as to each matter the shareholder proposes to bring before the annual meeting (a) a brief description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting; (b) the name and address of the shareholder proposing such business; (c) the class and number of share of the corporation
which are beneficially owned by the shareholder; (d) any material interest of the shareholder in such business; and (e) such other information regarding such business as would be
required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had the matter been proposed by the Board of Directors. Notwithstanding
anything in these Bylaws to the contrary, no business shall be considered properly brought before an annual meeting by a shareholder unless it is brought in accordance with the procedures set forth in

majority of directors present at a duly held meeting at the time the action is taken or the affirmative vote of the holders of a majority of the voting power of the shares present and entitled to vote
on that item of business, considered for this purpose as one class. Except as otherwise provided by law or by these bylaws, the directors of the corporation shall be elected at the Annual Meeting of

Shareholders after their election. In case of any increase or decrease in the number of directors, the increase or decrease shall be distributed among the several classes as nearly equal as possible,
as shall be determined by the affirmative vote of a majority of directors present at a duly held meeting at the time the action is taken or by the affirmative vote of the holders of a majority of the
voting power of the shares present and entitled to vote on that item of business. 

    Section 3.03  Nomination of Director Candidates.  Nomination of candidates for election to the
Board of Directors of the corporation at any annual meeting of the shareholders may be made only by or at the direction of the Board of Directors or by a shareholder entitled to vote at such annual
meeting. All such nominations, except those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the corporation. To be timely,
any such notice must be received at the principal executive offices of the corporation not less than 120 days in advance of the date of the corporation's proxy statement released to
shareholders in connection with the previous year's annual meeting of shareholders, except that if no annual meeting was held in the previous year or the date of the annual meeting has been changed by

3

 

notice; (ii) the name and address of the shareholder giving the notice as the same appears in the corporation's stock register; (iii) the number of shares of capital stock of the
corporation which are beneficially owned by each such nominee and by such shareholder; and (iv) such other information concerning each such nominee as would be required soliciting proxies for
the election of such nominee.
Such notice must also include a signed consent of each such nominee to serve as a director of the corporation, if elected. 

    If
the officer of the corporation presiding at an annual meeting of the shareholders determines that a director nomination was not made in accordance with the foregoing procedures,
such nomination shall be void and shall be disregarded for all purposes. 

    Section 3.04.  Determination of Contested Elections.  In the event that there are more candidates
for election to the Board of Directors at a meeting of the shareholders than there are directors to be elected at such meeting (a "Contested Election"), the vote for election of directors shall be by
ballot and the officer of the corporation presiding at the meeting shall appoint two persons, who need not be shareholders, to act as Inspectors of Election at such meeting. 

    The
Inspectors so appointed, before entering on the discharge of their duties, shall take and subscribe on oath or affirmation faithfully to execute the duties of Inspectors at such
meeting with strict impartiality and according to the best of their ability, and thereupon the Inspectors shall take charge of the polls and after the balloting shall canvas the votes and determine in
accordance with law and make a certificate to the corporation of the results of the vote taken. No director or candidate for the office of director shall be appointed an Inspector. 

    The
nominees for election to the Board of Directors in a Contested Election who are certified by the Inspectors as having been elected shall be deemed to be duly elected and qualified
upon the expiration of three business days following the date of such certification; provided that, in the event any court proceedings are commenced which challenge the results of such Contested
Election, such nominees shall not be deemed to be duly elected and qualified until all such court proceedings, including appeals, shall have been finally concluded. 

    Section 3.05.  Chairman of the Board.  The Board of Directors may elect from their number, a
Chairman of the Board, who shall not be deemed an officer of the Corporation as a result of such title. The Chairman of the Board, if one is elected, shall preside at all meetings of the directors and
shall have such other duties as may be prescribed, from time to time, by the Board of Directors. 

    Section 3.06.  Board Meetings.  Meetings of the Board of Directors may be held from time to time

mail, telephone, telegram or in person. 

    Section 3.08.  Waiver of Notice.  Notice of any meeting of the Board of Directors may be waived by
any director either before, at, or after such meeting orally or in a writing signed by such director. A director, by his attendance at any meeting of the Board of Directors, shall be deemed to have
waived notice of such meeting, except where the director objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and does not
participate thereafter in the meeting. 

    Section 3.09.  Quorum.  A majority of the directors holding office immediately prior to a meeting
of the Board of Directors shall constitute a quorum for the transaction of business at such meeting.

    Section 3.10.  Absent Directors.  A director may give advance written consent or opposition to a
proposal to be acted on at a meeting of the Board of Directors. If such director is not present at the meeting, consent or opposition to a proposal does not constitute presence for purposes of
determining the existence of a quorum, but consent or opposition shall be counted as a vote in favor of or against the proposal and shall be entered in the minutes or other record of action at the
meeting, if the proposal acted on at the meeting is substantially the same or has substantially the same effect as the proposal to which the director has consented or objected. 

    Section 3.11.  Conference Communications.  Any or all directors may participate in any meeting of
the Board of Directors, or of any duly constituted committee thereof, by any means of communication through which the directors may simultaneously hear each other during such meeting. For the purposes
of establishing a quorum and taking any action at the meeting, such directors participating pursuant to this Section 3.10 shall be deemed present in person at the meeting, and the place of the
meeting shall be the place or origination of the conference communication. 

    Section 3.12.  Vacancies: Newly Created Directorships.  Vacancies in the Board of Directors of
this corporation occurring by reason of death, resignation, removal or disqualification shall be filled for the unexpired term by a majority of the remaining directors of the Board although less than
a quorum; newly created directorships resulting from an increase in the authorized number of directors by action
of the Board of Directors as permitted by Section 3.02 may be filled by the affirmative vote of a majority of directors present at a duly held meeting at the time the action is taken. 

    Section 3.13.  Removal.  Any or all of the directors may be removed from office at any time, with
or without cause, by the affirmative vote of the holders of not less than 662/3 percent of the outstanding shares of Common Stock of the corporation or by the affirmative vote of
662/3 percent of the directors in office at the time the vote is taken. In the event that the entire Board or any one or more directors be so removed, new directors shall be elected at
the same meeting. 

    Section 3.14  Committees.  A resolution approved by the affirmative vote of a majority of the
Board of Directors may establish committees having the authority of the Board in the management of the business of the corporation to the extent provided in the resolution. A committee shall consist
of one or more persons, who need not be directors, appointed by affirmative vote of a majority of the directors present. Committees are subject to the direction and control of the Board of Directors,
except for special litigation committees, and vacancies in the membership thereof shall be filed by the Board of Directors. 

    A
majority of the members of the committee present at a meeting is a quorum for the transaction of business, unless a larger or smaller proportion or number is provided in a
resolution approved by the affirmative vote of a majority of directors present. 

    Section 3.15.  Written Action.  Any action which might be taken at a meeting of the Board of
Directors, or any duly constituted committee thereof, may be taken without a meeting if done in writing and signed by all of the directors or committee members, unless the Articles provide otherwise
and the action need not be approved by the shareholders. 

    Section 3.16.  Compensation.  Directors who are not salaried officers of this corporation shall
receive such fixed sum per meeting attended or such fixed annual sum as shall be determined, from time to time, by resolution of the Board of Directors. The Board of Directors may, by resolution,

any director from serving this corporation in any other capacity and receiving proper compensation therefor.

clauses (vii) and (viii) (less the amount of the proceeds of such debt so
incurred used to pay (A) the consideration for the Sierra Acquisition in an
amount not exceeding $24,000,000 plus reasonable fees and expenses as described

merger (such Recapitalization and all transactions related thereto, including
those described in the first recital through the sixth recital hereto, being
herein referred to as the "Original Transaction");

      WHEREAS, in connection with the Original Transaction, (i) the Other Asset
Contributors received cash in consideration for the redemption of their shares
by Holdco, (ii) the shares of Acquisition Subco held by Acquisition LLC were

                        DEFINITIONS AND ACCOUNTING TERMS

      SECTION 1.1. Defined Terms. The following terms (whether or not
underscored) when used in this Agreement, including its preamble and recitals,
shall, except where the context otherwise requires, have the following meanings
(such meanings to be equally applicable to the singular and plural forms
thereof):

      "Acquired Controlled Person" means any Person (i) in which the Borrower or
any of its Restricted Subsidiaries has made an Investment permitted under clause
(l)(i)(y) of Section 7.2.5 and (ii) as to which the Borrower or such Restricted

                                       -5-
<PAGE>

hereof, "control" means the power to appoint a majority of the board of

      "Affiliate" of any Person means any other Person which, directly or

Administrative Agent shall take effect at the opening of business on the day of
such establishment or announcement. As used herein, the reference rate shall
mean an index rate determined by the Administrative Agent from time to time as a
means of pricing certain extensions of credit and is neither directly tied to
any external rate of interest or index nor necessarily the lowest rate of
interest charged by the Administrative Agent at any given time.

required to be delivered by the Borrower to the Administrative Agent pursuant to
clause (c) of Section 7.1.1, a fee which shall accrue at a rate of 1/2 of 1% per
annum, and (ii) for each day thereafter, a fee which shall accrue at the
applicable rate per annum set forth below under the column entitled "Applicable
Commitment Fee", determined by reference to the applicable Leverage Ratio
referred to below:

                                                          Applicable
                Leverage Ratio                          Commitment Fee
                --------------                          --------------

                greater than or
                equal to 4.0:1.0                            0.500%

               less than 4.0:1.0                            0.375%

      The Leverage Ratio used to compute the Applicable Commitment Fee for any
day referred to in clause (ii) above shall be the Leverage Ratio set forth in
the Compliance Certificate most recently delivered by the Borrower to the
Administrative Agent on or prior to such day pursuant to clause (c) of Section
7.1.1. Changes in the Applicable Commitment Fee resulting from a change in the
Leverage Ratio shall become effective on the first day following delivery by the
Borrower to the Administrative Agent of a new Compliance Certificate pursuant to
clause (c) of Section 7.1.1. If the Borrower shall fail to deliver a Compliance
Certificate within the number of days after the end of any Fiscal Quarter as
required pursuant to clause (c) of Section 7.1.1 (without giving effect to any
grace period), the Applicable Commitment Fee from and including the first day
after the date on which such Compliance Certificate was required to be delivered
to and including the date the Borrower delivers to the Administrative Agent the
next Compliance Certificate shall conclusively equal the highest Applicable
Commitment Fee set forth above. Notwithstanding the foregoing, the Borrower may,
in its sole discretion, within ten Business Days following the end of any Fiscal
Quarter, deliver to the Administrative Agent a written estimate (the "Leverage
Ratio Estimate") setting forth the Borrower's good faith estimate of the
Leverage Ratio (based on calculations contained in an estimated Compliance
Certificate) that will be set forth in the next Compliance Certificate required
to be delivered by the Borrower to the Administrative Agent pursuant to clause
(c) of Section 7.1.1. In the event that the Leverage Ratio Estimate indicates
that there would be a change in the Applicable Commitment Fee resulting from a
change in the Leverage Ratio, such change will become effective on the first day

                                       -7-
<PAGE>

following delivery of the Leverage Ratio Estimate. In the event that, once the
next Compliance Certificate is delivered, the Leverage Ratio as set forth in
such Compliance Certificate differs from that calculated in the Leverage Ratio
Estimate delivered for the Fiscal Quarter with respect to which such Compliance
Certificate has been delivered, and such difference results in an Applicable
Commitment Fee which is greater than the Applicable Commitment Fee theretofore
in effect, then (A) such greater Applicable Commitment Fee shall be deemed to be
in effect for all purposes of this Agreement from the first day following the
delivery of the Leverage Ratio Estimate and (B) if the Borrower shall have
theretofore made any payment of commitment fees in respect of the period from
the first day following the delivery of the Leverage Ratio Estimate to the
actual date of delivery of such Compliance Certificate, then, on the next
Quarterly Payment Date, the Borrower shall pay as a supplemental payment of
commitment fees, an amount which equals the difference between the amount of
commitment fees that would otherwise have been paid based on such new Leverage
Ratio and the amount of such commitment fees actually so paid.

      "Applicable Margin" means at all times during the applicable periods set
forth below,

            (a) with respect to the unpaid principal amount of each (i) Term-B
      Loan maintained as a (A) Base Rate Loan, 2.50% per annum and (B) LIBO Rate
      Loan, 3.75% per annum and (ii) Term-C Loan maintained as a (A) Base Rate
      Loan, 2.00% per annum and (B) LIBO Rate Loan, 3.25% per annum;

            (b) from the Amendment Effective Date through (but excluding) the
      date upon which the Compliance Certificate for the Fiscal Quarter ending
      December 31, 2000 is delivered by the Borrower to the Administrative Agent
      pursuant to clause (c) of Section 7.1.1, with respect to the unpaid
      principal amount of each (i) Swing Line Loan (which shall be borrowed and
      maintained only as a Base Rate Loan) and each Revolving Loan and Term-A
      Loan maintained as a Base Rate Loan, 0.50% per annum, and (ii) Revolving
      Loan and Term-A Loan maintained as a LIBO Rate Loan, 1.75% per annum; and

            (c) at all times after the date of delivery of the Compliance
      Certificate described in clause (b) above, with respect to the unpaid
      principal amount of each Swing Line Loan (which shall be borrowed and
      maintained only as a Base Rate Loan) and each Revolving Loan and Term-A
      Loan, the rate determined by reference to the applicable Leverage Ratio
      and at the applicable percentage per annum set forth below under the
      column entitled "Applicable Margin for Base Rate Loans", in the case of
      Base Rate Loans, or by reference to the applicable Leverage Ratio and at
      the applicable percentage per annum set forth below under the column
      entitled "Applicable Margin for LIBO Rate Loans" in the case of LIBO Rate
      Loans:

greater than or equal to 4.0:1.0 and
          less than 5.0:1.0                    1.50%                  2.75%

greater than or equal to 3.0:1.0 and
          less than 4.0:1.0                    1.00%                  2.25%

          less than 3.0:1.0                    0.50%                  1.75%

      The Leverage Ratio used to compute the Applicable Margin for Swing Line
Loans, Revolving Loans and Term-A Loans for any day referred to in clause (c)
above shall be the Leverage Ratio set forth in the Compliance Certificate most
recently delivered by the Borrower to the Administrative Agent on or prior to
such day pursuant to clause (c) of Section 7.1.1. Changes in the Applicable
Margin for Swing Line Loans, Revolving Loans and Term-A Loans resulting from a
change in the Leverage Ratio shall become effective on the first day following
delivery by the Borrower to the Administrative Agent of a new Compliance
Certificate pursuant to clause (c) of Section 7.1.1. If the Borrower shall fail
to deliver a Compliance Certificate within the number of days after the end of
any Fiscal Quarter as required pursuant to clause (c) of Section 7.1.1 (without
giving effect to any grace period), the Applicable Margin for Swing Line Loans,
Revolving Loans and Term-A Loans from and including the first day after the date
on which such Compliance Certificate was required to be delivered to the date
the Borrower delivers to the Administrative Agent the next Compliance
Certificate shall conclusively equal the highest Applicable Margin for Swing
Line Loans, Revolving Loans and Term-A Loans set forth above. Notwithstanding
the foregoing, the Borrower may, in its sole discretion, within ten Business
Days following the end of any Fiscal Quarter, deliver to the Administrative
Agent a Leverage Ratio Estimate setting forth the Borrower's good faith estimate
of the Leverage Ratio (based on calculations set forth in an estimated
Compliance Certificate) that will be set forth in the next Compliance
Certificate required to be delivered by the Borrower to the Administrative Agent
pursuant to clause (c) of Section 7.1.1. In the event that the Leverage Ratio
Estimate indicates that there would be a change in the Applicable Margin
resulting from a change in the Leverage Ratio, such change will become effective
on the first day following delivery of the Leverage Ratio Estimate. In the event
that, once the next Compliance Certificate is delivered, the Leverage Ratio as
set forth in such Compliance Certificate differs from that calculated in the
Leverage Ratio Estimate delivered for the Fiscal Quarter with respect to which
such Compliance Certificate has been delivered, and such difference results in
an Applicable Margin which is greater than the Applicable Margin theretofore in
effect, then (A) such greater Applicable Margin shall be deemed

                                       -9-
<PAGE>

to be in effect for all purposes of this Agreement from the first day following
the delivery of the Leverage Ratio Estimate and (B) if the Borrower shall have
theretofore made any payment of interest in respect of Swing Line Loans,
Revolving Loans or Term-A Loans, or of letter of credit fees pursuant to the
first sentence of Section 3.3.3, in any such case in respect of the period from
the first day following the delivery of the Leverage Ratio Estimate to the
actual date of delivery of such Compliance Certificate, then, on the next
Quarterly Payment Date, the Borrower shall pay as a supplemental payment of
interest and/or letter of credit fees, an amount which equals the difference
between the amount of interest and letter of credit fees that would otherwise
have been paid based on such new Leverage Ratio and the amount of such interest
and letter of credit fees actually so paid.

      Swing Line Lender described in this clause (b) is herein referred to as
      its "Swing Line Loan Commitment". On the terms and subject to the
      conditions hereof, the Borrower may from time to time borrow, prepay and
      reborrow Swing Line Loans.

            (c) At any time that no Default has occurred and is continuing, and
      prior to the Revolving Loan Commitment Termination Date, the Borrower may
      notify the Agents that the Borrower is requesting that, on the terms and
      subject to the conditions contained in this Agreement, the Lenders and/or
      other lenders not then a party to this Agreement

                                      -43-
<PAGE>

      provide up to an aggregate amount of $25,000,000 in additional Revolving
      Loan Commitments. Upon receipt of such notice, the Syndication Agent shall
      use commercially reasonable efforts to arrange for the Lenders or other
      Eligible Institutions to provide such additional Revolving Loan
      Commitments; provided that the Syndication Agent will first offer each of
      the Lenders that then has a Percentage of the Revolving Loan Commitment a
      pro rata portion of any such additional Revolving Loan Commitment.
      Alternatively, CSFB may commit to provide the full amount of the requested
      additional Revolving Loan Commitment and then offer portions of such
      additional Revolving Loan Commitment to the Lenders or other Eligible
      Institutions, subject to the proviso to the immediately preceding
      sentence. Nothing contained in this clause (c) or otherwise in this
      Agreement is intended to commit any Lender or any Agent to provide any
      portion of any such additional Revolving Loan Commitments. If and to the
      extent that any Lenders and/or other lenders agree, in their sole
      discretion, to provide any such additional Revolving Loan Commitments, (i)
      the Revolving Loan Commitment Amount shall be increased by the amount of
      the additional Revolving Loan Commitments agreed to be so provided, (ii)
      the Percentages of the respective Lenders in respect of the Revolving Loan
      Commitment shall be proportionally adjusted (provided that the Percentage
      of each Lender shall not be increased without the consent of such Lender),
      (iii) at such time and in such manner as the Borrower and the Syndication
      Agent shall agree (it being understood that the Borrower and the Agents
      will use commercially reasonable efforts to avoid the prepayment or
      assignment of any LIBO Rate Loan on a day other than the last day of the
      Interest Period applicable thereto), the Lenders shall assign and assume
      outstanding Revolving Loans and participations in outstanding Letters of
      Credit so as to cause the amounts of such Revolving Loans and
      participations in Letters of Credit held by each Lender to conform to the
      respective Percentages of the Revolving Loan Commitment of the Lenders and
      (iv) the Borrower shall execute and deliver any additional Notes or other
      amendments or modifications to this Agreement or any other Loan Document
      as the Agents may reasonably request.

      SECTION 2.1.3. Letter of Credit Commitment. Subject to compliance by the
Borrower with the terms of Article III of the Amendment Agreement and Section
2.1.5 and 5.2, from time to time on any Business Day occurring concurrently with
(or after) the Amendment Effective Date but prior to the Revolving Loan
Commitment Termination Date, the applicable Issuer will (i) issue one or more
standby or commercial letters of credit (each referred to as a "Letter of
Credit") for the account of the Borrower or any of its Restricted Subsidiaries
in the Stated Amount requested by the Borrower on such day, or (ii) extend the
Stated Expiry Date of an existing standby or commercial Letter of Credit
previously issued hereunder to a date not later than the earlier of (x) the
sixth anniversary of the Closing Date and (y) one year from the date of such
extension (subject to automatic renewal provisions); provided that,
notwithstanding the terms of this clause (y), a Letter of Credit may, if
required by the beneficiary thereof, contain automatic renewal provisions
pursuant to which the Stated Expiry Date shall be automatically extended (to a
date not beyond the date specified in clause (x) above), unless notice to the
contrary shall have been given to the beneficiary prior to the then existing
Stated Expiry Date in accordance with the

                                      -44-
<PAGE>

terms specified in such Letter of Credit by the applicable Issuer or the account
party of such Letter of Credit (which notice by the account party shall also
have been provided to the applicable Issuer in writing).

      SECTION 2.1.4. Lenders Not Permitted or Required to Make the Loans. No
Lender shall be permitted or required to, and the Borrower shall not request any
Lender to, make

            (a) any Term-C Loan if, after giving effect thereto, the aggregate
      original principal amount of all the Term-C Loans of such Lender would
      exceed such Lender's Percentage of the Term-C Loan Commitment Amount;

            (b) any Revolving Loan if, after giving effect thereto, the
      aggregate outstanding principal amount of all the Revolving Loans (i) of
      all the Lenders with Revolving Loan Commitments, together with the Letter
      of Credit Outstandings and the aggregate outstanding principal amount of
      all Swing Line Loans, would exceed the then existing Revolving Loan
      Commitment Amount, or (ii) of such Lender, together with such Lender's
      Percentage of the aggregate amount of all Letter of Credit Outstandings,
      and such Lender's Percentage of the outstanding principal amount of all
      Swing Line Loans, would exceed such Lender's Percentage of the then
      existing Revolving Loan Commitment Amount.

            (c) any Swing Line Loan if, after giving effect thereto (i) the
      aggregate outstanding principal amount of all Swing Line Loans would
      exceed the Swing Line Loan Commitment Amount or (ii) the sum of the
      aggregate amount of all Letter of Credit Outstandings plus the aggregate
      principal amount of all Revolving Loans and Swing Line Loans then
      outstanding would exceed the then existing Revolving Loan Commitment
      Amount.

      SECTION 2.1.5. Issuer Not Permitted or Required to Issue Letters of
Credit. No Issuer shall be permitted or required to issue any Letter of Credit
if, after giving effect thereto, (a) the aggregate amount of all Letter of
Credit Outstandings would exceed the Letter of Credit Commitment Amount or (b)
the sum of the aggregate amount of all Letter of Credit Outstandings plus the
aggregate principal amount of all Revolving Loans and Swing Line Loans then
outstanding would exceed the then existing Revolving Loan Commitment Amount.

      SECTION 2.2. Reduction of Revolving Loan Commitment Amount. The Borrower
may, from time to time on any Business Day occurring after the Closing Date,
voluntarily reduce the Revolving Loan Commitment Amount; provided, however, that
all such reductions shall require at least three Business Days' prior notice to
the Administrative Agent and be permanent, and any partial reduction of any
Commitment Amount shall be in an aggregate amount of $500,000 or any larger
integral multiple of $100,000. Any such reduction of the Revolving Loan
Commitment Amount which reduces the Revolving Loan Commitment Amount below the
Letter of Credit Commitment Amount or the Swing Line Loan Commitment Amount
shall result in an automatic

                                      -45-
<PAGE>

and corresponding reduction of the Letter of Credit Commitment Amount or the
Swing Line Loan Commitment Amount, as the case may be, to an aggregate amount
not in excess of the Revolving Loan Commitment Amount, as so reduced, without
any further action on the part of the applicable Issuer or the Swing Line
Lender.

      SECTION 2.3. Borrowing Procedures and Funding Maintenance. Term-C Loans
and Revolving Loans shall be made by the Lenders in accordance with Section
2.3.1, and Swing Line Loans shall be made by the Swing Line Lender in accordance
with Section 2.3.2.

      SECTION 2.3.1. Term-C Loans and Revolving Loans. By delivering a Borrowing
Request to the Administrative Agent on or before 12:00 p.m. (noon), Designated
City time, on a Business Day, the Borrower may from time to time irrevocably
request, on not less than one Business Day's notice (in the case of Base Rate
Loans) or three Business Days' notice (in the case of LIBO Rate Loans) nor more
than five Business Days' notice (in the case of any Loans), that a Borrowing
consisting of Term-C Loans and/or Revolving Loans be made in an aggregate amount
of $500,000 or any larger integral multiple of $100,000, or in the unused amount
of the applicable Commitment. No Borrowing Request shall be required, and the
minimum aggregate amounts specified under this Section 2.3.1 shall not apply, in
the case of Revolving Loans made under clause (b) of Section 2.3.2 to refund
Refunded Swing Line Loans or Revolving Loans deemed made under Section 2.6.2 in
respect of unreimbursed Disbursements. On the terms and subject to the
conditions of this Agreement, each Borrowing shall be comprised of the type of
Loans, and shall be made on the Business Day, specified in such Borrowing
Request. On or before 1:00 p.m., Designated City time, on such Business Day each
Lender shall deposit with the Administrative Agent same day funds in an amount
equal to such Lender's Percentage of the requested Borrowing. Such deposit will
be made to an account which the Administrative Agent shall specify from time to
time by notice to the Lenders. To the extent funds are received from the
Lenders, the Administrative Agent shall make such funds available to the
Borrower by wire transfer to the accounts the Borrower shall have specified in
its Borrowing Request. No Lender's obligation to make any Loan shall be affected
by any other Lender's failure to make any Loan.

      SECTION 2.3.2. Swing Line Loans. (a) By telephonic notice, promptly
followed (within one Business Day) by the delivery of a confirming Borrowing
Request, to the Swing Line Lender and the Administrative Agent on or before
10:00 a.m., Designated City time, on the Business Day the proposed Swing Line
Loan is to be made, the Borrower may from time to time irrevocably request that
a Swing Line Loan be made by the Swing Line Lender in a minimum principal amount
of $500,000 or any larger integral multiple of $100,000. All Swing Line Loans
shall be made as Base Rate Loans and shall not be entitled to be converted into
LIBO Rate Loans. The proceeds of each Swing Line Loan shall be made available by
the Swing Line Lender, by 3:00 p.m., Designated City time, on the Business Day
telephonic notice is received by it as provided in this clause (a), to the
Borrower by wire transfer to the account the Borrower shall have specified in
its notice therefor.

                                      -46-
<PAGE>

      (b) If (i) any Swing Line Loan shall be outstanding for more than four
Business Days or (ii) any Default shall occur and be continuing, each Lender
with a Revolving Loan Commitment (other than the Swing Line Lender) irrevocably
agrees that it will, at the request of the Swing Line Lender and upon notice
from the Administrative Agent, unless such Swing Line Loan shall have been
earlier repaid in full, make a Revolving Loan (which shall initially be funded
as a Base Rate Loan) in an amount equal to such Lender's Percentage in respect
of the Revolving Loan Commitments of the aggregate principal amount of all such
Swing Line Loans then outstanding (such outstanding Swing Line Loans hereinafter
referred to as the "Refunded Swing Line Loans"); provided, that the Swing Line
Lender shall not request, and no Lender with a Revolving Loan Commitment shall
make, any Refunded Swing Line Loan if, after giving effect to the making of such
Refunded Swing Line Loan, the sum of all Swing Line Loans and Revolving Loans
made by such Lender, plus such Lender's Percentage in respect of the Revolving
Loan Commitments of the aggregate amount of all Letter of Credit Outstandings,
would exceed such Lender's Percentage of the then existing Revolving Loan
Commitment Amount. On or before 12:00 p.m., Designated City time, on the first
Business Day following receipt by each Lender of a request to make Revolving
Loans as provided in the preceding sentence, each such Lender with a Revolving
Loan Commitment shall deposit in an account specified by the Swing Line Lender
the amount so requested in same day funds and such funds shall be applied by the
Swing Line Lender to repay the Refunded Swing Line Loans. At the time the
aforementioned Lenders make the above referenced Revolving Loans, the Swing Line
Lender shall be deemed to have made, in consideration of the making of the
Refunded Swing Line Loans, a Revolving Loan in an amount equal to the Swing Line
Lender's Percentage in respect of the Revolving Loan Commitments of the
aggregate principal amount of the Refunded Swing Line Loans. Upon the making (or
deemed making, in the case of the Swing Line Lender) of any Revolving Loans
pursuant to this clause (b), the amount so funded shall become outstanding as a
Revolving Loan of such Lender and to the extent to made (or deemed made, in the
case of the Swing Line Lender) shall no longer constitute a portion of the
applicable Swing Line Loan. All interest payable with respect to any Revolving
Loans made (or deemed made, in the case of the Swing Line Lender) pursuant to
this clause (b) shall be appropriately adjusted to reflect the period of time
during which the Swing Line Lender had outstanding Swing Line Loans in respect
of which such Revolving Loans were made. Each Lender's obligation (in the case
of Lenders with a Revolving Loan Commitment) to make the Revolving Loans
referred to in this clause (b) shall be absolute and unconditional and shall not
be affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right which such Lender may have against the Swing
Line Lender, the Borrower or any other Person for any reason whatsoever; (ii)
the occurrence or continuance of any Default; (iii) any adverse change in the
condition (financial or otherwise) of the Borrower or any other Obligor; (iv)
the acceleration or maturity of any Loans or the termination of any Commitment
after the making of any Swing Line Loan; (v) any breach of this Agreement or any
other Loan Document by the Borrower or any Lender; or (vi) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

      SECTION 2.3.3. Existing Revolving Loans, Existing Term-A Loans and
Existing Term-B Loans. As of the Amendment Effective Date, the Existing
Revolving Loans, the Existing Term-A

                                      -47-
<PAGE>

Loans and the Existing Term-B Loans originally made under the Existing Credit
Agreement shall remain outstanding hereunder as Revolving Loans, Term-A Loans
and Term-B Loans, respectively, in each case, as if made hereunder on the
Amendment Effective Date. No amounts paid or prepaid with respect to Term-A
Loans or Term-B Loans may be reborrowed.

      SECTION 2.4. Continuation and Conversion Elections. By delivering a
Continuation/Conversion Notice to the Administrative Agent on or before 12:00
p.m. (noon), Designated City time, on a Business Day, the Borrower may from time
to time irrevocably elect, on not less than one Business Day's notice (in the
case of a conversion of LIBO Rate Loans to Base Rate Loans) or three Business
Days' notice (in the case of a continuation of LIBO Rate Loans or a conversion
of Base Rate Loans into LIBO Rate Loans) nor more than five Business Days'
notice (in the case of any Loans) that all, or any portion in a minimum amount
of $500,000 or any larger integral multiple of $100,000, be, in the case of Base
Rate Loans, converted into LIBO Rate Loans or, in the case of LIBO Rate Loans,
converted into Base Rate Loans or continued as LIBO Rate Loans (in the absence
of delivery of a Continuation/Conversion Notice with respect to any LIBO Rate
Loan at least three Business Days before the last day of the then current
Interest Period with respect thereto, such LIBO Rate Loan shall, on such last
day, automatically convert to a Base Rate Loan); provided, however, that (x)
each such conversion or continuation shall be pro rated among the applicable
outstanding Loans of the relevant Lenders, and (y) no portion of the outstanding
principal amount of any Loans may be continued as, or be converted into, LIBO
Rate Loans when any Default has occurred and is continuing.

      SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan, so long as such
action does not result in increased costs to the Borrower; provided, however,
that such LIBO Rate Loan shall nonetheless be deemed to have been made and to be
held by such Lender, and the obligation of the Borrower to repay such LIBO Rate
Loan shall nevertheless be to such Lender for the account of such foreign
branch, Affiliate or international banking facility; and provided, further,
however, that, except for purposes of determining whether any such increased
costs are payable by the Borrower, such Lender shall cause such foreign branch,
Affiliate or international banking facility to comply with the applicable
provisions of clause (b) of Section 4.6 with respect to such LIBO Rate Loan. In
addition, the Borrower hereby consents and agrees that, for purposes of any
determination to be made for purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall
be conclusively assumed that each Lender elected to fund all LIBO Rate Loans by
purchasing Dollar deposits in its LIBOR Office's interbank Eurodollar market.

      SECTION 2.6. Issuance Procedures. By delivering to the applicable Issuer
and the Administrative Agent an Issuance Request on or before 12:00 p.m. (noon),
Designated City time, on a Business Day, the Borrower may, from time to time
irrevocably request, on not less than five Business Days' notice (or such
shorter or longer notice as may be acceptable to the applicable Issuer), in the
case of an initial issuance of a Letter of Credit, and not less than five nor
more than

                                      -48-
<PAGE>

ten Business Days' notice (unless a shorter or longer notice period is
acceptable to the applicable Issuer) prior to the then existing Stated Expiry
Date of a Letter of Credit, in the case of a request for the extension of the
Stated Expiry Date of a Letter of Credit, that such Issuer issue, or extend the
Stated Expiry Date of, as the case may be, an irrevocable Letter of Credit on
behalf of the Borrower (whether issued for the account of or on behalf of the
Borrower or any of its Restricted Subsidiaries) in such form as may be requested
by the Borrower and approved by such Issuer, for the purposes described in
Section 7.1.9. Notwithstanding anything to the contrary contained herein or in
any separate application for any Letter of Credit, the Borrower hereby
acknowledges and agrees that it shall be obligated to reimburse the applicable
Issuer upon each Disbursement paid under a Letter of Credit, and it shall be
deemed to be the obligor for purposes of each such Letter of Credit issued
hereunder (whether the account party on such Letter of Credit is the Borrower or
a Subsidiary of the Borrower). Upon receipt of an Issuance Request, the
Administrative Agent shall promptly notify the applicable Issuer and each Lender
that has a Revolving Loan Commitment thereof. Each Letter of Credit shall by its
terms be stated to expire on a date (its "Stated Expiry Date") no later than the
earlier to occur of (i) the sixth anniversary of the Closing Date or (ii) one
year from the date of its issuance (subject to automatic renewal provisions);
provided that, notwithstanding the terms of this clause (ii), a Letter of Credit
may, if required by the beneficiary thereof, contain automatic renewal
provisions pursuant to which the Stated Expiry Date shall be automatically
extended (to a date not beyond the date specified in clause (i) above), unless
notice to the contrary shall have been given to the beneficiary prior to the
then existing Stated Expiry Date in accordance with the terms specified in such
Letter of Credit by the applicable Issuer or the account party of such Letter of
Credit (which notice by the account party shall also have been provided to the
applicable Issuer in writing). The applicable Issuer will make available to the
beneficiary thereof the original of each Letter of Credit which it issues
hereunder. In the event that the Issuer is other than the Administrative Agent,
such Issuer will send by facsimile transmission to the Administrative Agent,
promptly on the first Business Day of each week, its daily maximum amount
available to be drawn under the Letters of Credit issued by such Issuer for the
previous week. The Administrative Agent shall deliver to each Lender upon each
calendar month end, and upon each payment of the letter of credit fees payable
pursuant to Section 3.3.3, a report setting forth the daily maximum amount
available to be drawn for all Issuers during such period. Notwithstanding
anything to the contrary herein, any Issuance Request delivered to the
applicable Issuer or Administrative Agent by the Borrower by telecopier shall be
confirmed promptly in an original writing delivered to such Issuer or
Administrative Agent, as the case may be.

      SECTION 2.6.1. Other Lenders' Participation. Upon the issuance of each
Letter of Credit issued by an Issuer pursuant hereto, and without further
action, each Lender (other than such Issuer) that has a Revolving Loan
Commitment shall be deemed to have irrevocably purchased from such Issuer, to
the extent of its Percentage in respect of the Revolving Loan Commitments, and
such Issuer shall be deemed to have irrevocably granted and sold to such Lender
a participation interest in such Letter of Credit (including the Contingent
Liability and any Reimbursement Obligation and all rights with respect thereto),
and such Lender shall, to the extent of its Percentage in respect of the
Revolving Loan Commitments, be responsible for

                                      -49-
<PAGE>

reimbursing promptly (and in any event within one Business Day) the applicable
Issuer for Reimbursement Obligations which have not been reimbursed by the
Borrower in accordance with Section 2.6.3. In addition, such Lender shall, to
the extent of its Percentage in respect of the Revolving Loan Commitments, be
entitled to receive a ratable portion of the letter of credit fees payable
pursuant to Section 3.3.3 with respect to each Letter of Credit and of interest
payable pursuant to Section 3.2 with respect to any Reimbursement Obligation. To
the extent that any Lender has reimbursed the applicable Issuer for a
Disbursement as required by this Section, such Lender shall be entitled to
receive its ratable portion of any amounts subsequently received (from the
Borrower or otherwise) in respect of such Disbursement.

      SECTION 2.6.2. Disbursements; Conversion to Revolving Loans. The
applicable Issuer will notify the Borrower and the Administrative Agent promptly
of the presentment for payment of any drawing under any Letter of Credit issued
by such Issuer, together with notice of the date (the "Disbursement Date") such
payment shall be made (each such payment, a "Disbursement"). Subject to the
terms and provisions of such Letter of Credit and this Agreement, such Issuer
shall make such payment to the beneficiary (or its designee) of such Letter of
Credit. Prior to 12:30 p.m., Designated City time, on the first Business Day
following the Disbursement Date (the "Disbursement Due Date"), the Borrower will
reimburse the Administrative Agent, for the account of such Issuer, for all
amounts which such Issuer has disbursed under such Letter of Credit, together
with interest thereon at the rate per annum otherwise applicable to Revolving
Loans (made as Base Rate Loans) from and including the Disbursement Date to but
excluding the Disbursement Due Date and, thereafter (unless such Disbursement is
converted into a Base Rate Loan on the Disbursement Due Date), at a rate per
annum equal to the rate per annum then in effect with respect to overdue
Revolving Loans (made as Base Rate Loans) pursuant to Section 3.2.2 for the
period from the Disbursement Due Date through the date of such reimbursement;
provided, however, that, if no Default shall have then occurred and be
continuing, unless the Borrower has notified the Administrative Agent no later
than one Business Day prior to the Disbursement Due Date that it will reimburse
such Issuer for the applicable Disbursement, then the amount of the Disbursement
shall be deemed to be a Borrowing of Revolving Loans constituting Base Rate
Loans and following the giving of notice thereof by the Administrative Agent to
the Lenders, each Lender with a Revolving Loan Commitment (other than such
Issuer) will deliver to such Issuer on the Disbursement Due Date immediately
available funds in an amount equal to such Lender's Percentage of such
Borrowing. Each conversion of Disbursement amounts into Revolving Loans shall
constitute a representation and warranty by the Borrower that on the date of the
making of such Revolving Loans all of the statements set forth in Section 5.2.1
are true and correct.

      SECTION 2.6.3. Reimbursement. The obligation (a "Reimbursement
Obligation") of the Borrower under Section 2.6.2 to reimburse the applicable
Issuer with respect to each Disbursement (including interest thereon) not
converted into a Base Rate Loan pursuant to Section 2.6.2, and, upon the
Borrower failing or electing not to reimburse such Issuer and the giving of
notice thereof by the Administrative Agent to the Lenders, each Lender's (to the
extent it has a Revolving Loan Commitment) obligation under Section 2.6.1 to
reimburse such Issuer or

                                      -50-
<PAGE>

fund its Percentage of any Disbursement converted into a Base Rate Loan, shall
be absolute and unconditional under any and all circumstances and irrespective
of any setoff, counterclaim or defense to payment which the Borrower or such
Lender, as the case may be, may have or have had against such Issuer or any such
Lender, including any defense based upon the failure of any Disbursement to
conform to the terms of the applicable Letter of Credit (if, in such Issuer's
good faith opinion, such Disbursement is determined to be appropriate) or any
non-application or misapplication by the beneficiary of the proceeds of such
Letter of Credit; provided, however, that after paying in full its Reimbursement
Obligation hereunder, nothing herein shall adversely affect the right of the
Borrower or such Lender, as the case may be, to commence any proceeding against
such Issuer for any wrongful Disbursement made by such Issuer under a Letter of
Credit as a result of acts or omissions constituting gross negligence or willful
misconduct on the part of such Issuer.

      SECTION 2.6.4. Deemed Disbursements. Upon the occurrence and during the
continuation of any Event of Default of the type described in clauses (b)
through (d) of Section 8.1.9 with respect to any Obligor (other than
Subsidiaries that are not Material Subsidiaries) or, with notice from the
Administrative Agent acting at the direction of the Required Lenders, upon the
occurrence and during the continuation of any other Event of Default,

            (a) an amount equal to that portion of all Letter of Credit
      Outstandings attributable to the then aggregate amount which is undrawn
      and available under all Letters of Credit issued and outstanding shall,
      without demand upon or notice to the Borrower or any other Person, be
      deemed to have been paid or disbursed by the applicable Issuer under such
      Letters of Credit (notwithstanding that such amount may not in fact have
      been so paid or disbursed); and

            (b) upon notification by the Administrative Agent to the Borrower of
      its obligations under this Section, the Borrower shall be immediately
      obligated to reimburse the applicable Issuer for the amount deemed to have
      been so paid or disbursed by such Issuer.

Any amounts so payable by the Borrower pursuant to this Section shall be
deposited in cash with the Administrative Agent and held as collateral security
for the Obligations in connection with the Letters of Credit issued by the
applicable Issuer. At such time as the Events of Default giving rise to the
deemed disbursements hereunder shall have been cured or waived, the
Administrative Agent shall return to the Borrower all amounts then on deposit
with the Administrative Agent pursuant to this Section, together with accrued
interest at the Federal Funds Rate, which have not been applied to the
satisfaction of such Obligations.

      SECTION 2.6.5. Nature of Reimbursement Obligations. The Borrower and, to
the extent set forth in Section 2.6.1, each Lender with a Revolving Loan
Commitment, shall assume all risks of the acts, omissions or misuse of any
Letter of Credit by the beneficiary thereof. No

                                      -51-
<PAGE>

Issuer (except to the extent of its own gross negligence or willful misconduct)
shall be responsible for:

            (a) the form, validity, sufficiency, accuracy, genuineness or legal
      effect of any Letter of Credit or any document submitted by any party in
      connection with the application for and issuance of a Letter of Credit,
      even if it should in fact prove to be in any or all respects invalid,
      insufficient, inaccurate, fraudulent or forged;

            (b) the form, validity, sufficiency, accuracy, genuineness or legal
      effect of any instrument transferring or assigning or purporting to
      transfer or assign a Letter of Credit or the rights or benefits thereunder
      or the proceeds thereof in whole or in part, which may prove to be invalid
      or ineffective for any reason;

            (c) failure of the beneficiary to comply fully with conditions
      required in order to demand payment under a Letter of Credit;

            (d) errors, omissions, interruptions or delays in transmission or
      delivery of any messages, by mail, cable, telegraph, telex or otherwise;
      or

            (e) any loss or delay in the transmission or otherwise of any
      document or draft required in order to make a Disbursement under a Letter
      of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any Lender with a Revolving Loan
Commitment hereunder. In furtherance and extension and not in limitation or
derogation of any of the foregoing, any action taken or omitted to be taken by
the applicable Issuer in good faith (and not constituting gross negligence or
willful misconduct) shall be binding upon the Borrower, each Obligor and each
such Lender, and shall not put such Issuer under any resulting liability to the
Borrower, any Obligor or any such Lender, as the case may be.

      SECTION 2.6.6. Existing Letters of Credit. Notwithstanding anything to the
contrary herein, the Letters of Credit outstanding under and as defined in the
Existing Credit Agreement shall be deemed to be Letters of Credit outstanding
hereunder as if issued on the Amendment Effective Date.

      SECTION 2.7. Register; Notes.

            (a) Each Lender may maintain in accordance with its usual practice
      an account or accounts evidencing the Indebtedness of the Borrower to such
      Lender resulting from each Loan made by such Lender, including the amounts
      of principal and interest payable and paid to such Lender from time to
      time hereunder. In the case of a Lender that does not request, pursuant to
      clause (b)(ii) below, execution and delivery of a Note evidencing the
      Loans made by such Lender to the Borrower, such account or accounts shall,
      to the extent

                                      -52-
<PAGE>

      not inconsistent with the notations made by the Administrative Agent in
      the Register, be conclusive and binding on the Borrower absent manifest
      error; provided, however, that the failure of any Lender to maintain such
      account or accounts shall not limit or otherwise affect any Obligations of
      the Borrower or any other Obligor.

            (b)(i) The Borrower hereby designates the Administrative Agent to
      serve as the Borrower's agent, solely for the purpose of this clause (b),
      to maintain a register (the "Register") on which the Administrative Agent
      will record each Lender's Commitments, the Loans made by each Lender and
      each repayment in respect of the principal amount of the Loans of each
      Lender and annexed to which the Administrative Agent shall retain a copy
      of each Lender Assignment Agreement delivered to the Administrative Agent
      pursuant to Section 10.11.1. Failure to make any recordation, or any error
      in such recordation, shall not affect the Borrower's obligation in respect
      of such Loans. The entries in the Register shall be conclusive, in the
      absence of manifest error, and the Borrower, the Administrative Agent and
      the Lenders shall treat each Person in whose name a Loan (and as provided
      in clause (ii) the Note evidencing such Loan, if any) is registered as the
      owner thereof for all purposes of this Agreement, notwithstanding notice
      or any provision herein to the contrary. A Lender's Commitment and the
      Loans made pursuant thereto may be assigned or otherwise transferred in
      whole or in part only by registration of such assignment or transfer in
      the Register. Any assignment or transfer of a Lender's Commitment or the
      Loans made pursuant thereto shall be registered in the Register only upon
      delivery to the Administrative Agent of a Lender Assignment Agreement duly
      executed by the assignor thereof. No assignment or transfer of a Lender's
      Commitment or the Loans made pursuant thereto shall be effective unless
      such assignment or transfer shall have been recorded in the Register by
      the Administrative Agent as provided in this Section.

            (ii) The Borrower agrees that, upon the request to the
      Administrative Agent by any Lender, the Borrower will execute and deliver
      to such Lender, as applicable, a Revolving Note, a Term-A Note, a Term-B
      Note, a Term-C Note and a Swing Line Note evidencing the Loans made by
      such Lender. The Borrower hereby irrevocably authorizes each Lender to
      make (or cause to be made) appropriate notations on the grid attached to
      such Lender's Notes (or on any continuation of such grid), which
      notations, if made, shall evidence, inter alia, the date of, the
      outstanding principal amount of, and the interest rate and Interest Period
      applicable to the Loans evidenced thereby. Such notations shall, to the
      extent not inconsistent with the notations made by the Administrative
      Agent in the Register, be conclusive and binding on the Borrower absent
      manifest error; provided, however, that the failure of any Lender to make
      any such notations or any error in any such notations shall not limit or
      otherwise affect any Obligations of the Borrower or any other Obligor. The
      Loans evidenced by any such Note and interest thereon shall at all times
      (including after assignment pursuant to Section 10.11.1) be represented by
      one or more Notes payable to the order of the payee named therein and its
      registered assigns. A Note and the obligation evidenced thereby may be
      assigned or otherwise transferred in

                                      -53-
<PAGE>

      whole or in part only by registration of such assignment or transfer of
      such Note and the obligation evidenced thereby in the Register (and each
      Note shall expressly so provide). Any assignment or transfer of all or
      part of an obligation evidenced by a Note shall be registered in the
      Register only upon surrender for registration of assignment or transfer of
      the Note evidencing such obligation, accompanied by a Lender Assignment
      Agreement duly executed by the assignor thereof, and thereupon, if
      requested by the assignee, one or more new Notes shall be issued to the
      designated assignee and the old Note shall be returned by the
      Administrative Agent to the Borrower marked "exchanged". No assignment of
      a Note and the obligation evidenced thereby shall be effective unless it
      shall have been recorded in the Register by the Administrative Agent as
      provided in this Section.

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

      SECTION 3.1. Repayments and Prepayments; Application.

      SECTION 3.1.1. Repayments and Prepayments. The Borrower shall repay in
full the unpaid principal amount of each Loan upon the Stated Maturity Date
therefor. Prior thereto, payments and repayments of Loans shall or may be made
as set forth below.

            (a) From time to time on any Business Day, the Borrower may make a
      voluntary prepayment, in whole or in part, of the outstanding principal
      amount of any

                  (i) Loans (other than Swing Line Loans); provided, however,
            that

                        (A) any such prepayment of the Term-A Loans, Term-B
                  Loans or Term-C Loans shall be made pro rata among Term-A
                  Loans, Term-B Loans and Term-C Loans, as applicable, of the
                  same type and, if applicable, having the same Interest Period
                  of all Lenders that have made such Term-A Loans, Term-B Loans
                  or Term-C Loans, and any such prepayment of Revolving Loans
                  shall be made pro rata among the Revolving Loans of the same
                  type and, if applicable, having the same Interest Period of
                  all Lenders that have made such Revolving Loans;

                        (B) the Borrower shall comply with Section 4.4 in the
                  event that any LIBO Rate Loan is prepaid on any day other than
                  the last day of the Interest Period for such Loan;

                        (C) all such voluntary prepayments shall require at
                  least one Business Day's notice in the case of Base Rate
                  Loans, three Business Days'

                  notice in the case of LIBO Rate Loans, but no more than five
                  Business Days' notice in the case of any Loans, in each case
                  in writing to the Administrative Agent; and

                        (D) all such voluntary partial prepayments shall be in
                  an aggregate amount of $500,000 or any larger integral
                  multiple of $100,000 or in the aggregate principal amount of
                  all Loans of the applicable Tranche and type then outstanding;
                  or

                  (ii) Swing Line Loans, provided that

                        (A) all such voluntary prepayments shall require prior
                  telephonic notice to the Swing Line Lender on or before 11:00
                  a.m., Designated City time, on the day of such prepayment
                  (such notice to be confirmed in writing by the Borrower within
                  24 hours thereafter); and

                        (B) all such voluntary partial prepayments shall be in
                  an aggregate amount of $500,000 and an integral multiple of
                  $100,000 or in the aggregate principal amount of all Swing
                  Line Loans then outstanding.

            (b) No later than five Business Days following the delivery by the
      Borrower of its annual audited financial reports required pursuant to
      clause (b) of Section 7.1.1 (beginning with the financial reports
      delivered in respect of the 2000 Fiscal Year), the Borrower shall deliver
      to the Administrative Agent a calculation of the Excess Cash Flow for the
      Fiscal Year last ended and, no later than five Business Days following the
      delivery of such calculation, make or cause to be made a mandatory
      prepayment of the Term Loans in an amount equal to 50% of the Excess Cash
      Flow (if any) for such Fiscal Year less (ii) the aggregate amount of all
      voluntary prepayments of the principal of the Term Loans actually made in
      such Fiscal Year pursuant to clause (a) of Section 3.1.1, to be applied as
      set forth in Section 3.1.2; provided, however, that such prepayment shall
      only be required to be made to the extent that the amount of Debt, as
      reduced by giving effect to such prepayment, would result in a Leverage
      Ratio of greater than 3.50:1 on a pro forma basis as of the date of such
      prepayment.

            (c) No later than one Business Day (in the case of Net Debt
      Proceeds) or 30 calendar days (in the case of Net Disposition Proceeds)
      following the receipt of any Net Disposition Proceeds or Net Debt Proceeds
      by (x) in the case of Net Debt Proceeds, Holdco, the Borrower or any
      Restricted Subsidiary of the Borrower and (y) in the case of Net
      Disposition Proceeds, the Borrower or any Restricted Subsidiary of the
      Borrower, the Borrower shall deliver to the Administrative Agent a
      calculation of the amount of such Net Disposition Proceeds or Net Debt
      Proceeds, as the case may be, and, to the extent the amount of such Net
      Disposition Proceeds or Net Debt Proceeds, as the case may be, with
      respect to any single transaction or series of related transactions,
      exceeds $2,000,000,

                                      -55-
<PAGE>

      make a mandatory prepayment of the Term Loans in an amount equal to 100%
      of such Net Disposition Proceeds or Net Debt Proceeds, as the case may be,
      to be applied as set forth in Section 3.1.2; provided, that no mandatory
      prepayment on account of such Net Disposition Proceeds shall be required
      under this clause if the Borrower informs the Agents no later than 30 days
      following the receipt of any Net Disposition Proceeds of its or its
      Restricted Subsidiary's good faith intention to apply such Net Disposition
      Proceeds to the acquisition of other assets or property consistent with
      the business permitted to be conducted pursuant to Section 7.2.1
      (including by way of merger or Investment) within 365 days following the
      receipt of such Net Disposition Proceeds, with the amount of such Net
      Disposition Proceeds unused after such 365 day period being applied to the
      Loans pursuant to Section 3.1.2.

            (d) The Borrower shall, concurrently with the receipt of any Net
      Equity Proceeds by Holdco, the Borrower or any Restricted Subsidiary of
      the Borrower, deliver to the Administrative Agent a calculation of the
      amount of such Net Equity Proceeds, and no later than five Business Days
      following the delivery of such calculation, and, to the extent that the
      amount of such Net Equity Proceeds with respect to any single transaction
      or series of related transactions exceeds $2,000,000, and subject to the
      proviso below, make or cause to be made a mandatory prepayment of the Term
      Loans in an amount equal to 50% of such Net Equity Proceeds to be applied
      as set forth in Section 3.1.2; provided, however, that such prepayment
      shall only be required to be made to the extent that the amount of Debt,
      as reduced by giving effect to such prepayment would result in a Leverage
      Ratio of greater than 3.50:1 on a pro forma basis as of the date of such
      prepayment (which pro forma calculation shall include, in the case of Net
      Equity Proceeds of the Initial Public Offering, the use of up to
      $60,000,000 of such Net Equity Proceeds to redeem Senior Subordinated
      Notes (including in such $60,000,000 amounts paid on account of principal
      of, and premium, if any, on, such Senior Subordinated Notes but excluding
      amounts paid on account of interest accrued on such Senior Subordinated
      Notes or fees in respect thereof));

            (e) The Borrower shall, no later than the 60th calendar day
      following the receipt by the Borrower or any of its Restricted
      Subsidiaries of any Casualty Proceeds in excess of $2,000,000
      (individually or in the aggregate in any Fiscal Year), make or cause to be
      made a mandatory prepayment of the Term Loans in an amount equal to 100%
      of such Casualty Proceeds, to be applied as set forth in Section 3.1.2;
      provided, that no mandatory prepayment on account of Casualty Proceeds
      shall be required under this clause if the Borrower informs the Agents no
      later than 60 days following the occurrence of the Casualty Event
      resulting in such Casualty Proceeds of its or its Restricted Subsidiary's
      good faith intention to apply such Casualty Proceeds to the rebuilding or
      replacement of the damaged, destroyed or condemned assets or property
      subject to such Casualty Event or the acquisition of other assets or
      property consistent with the business permitted to be conducted pursuant
      to Section 7.2.1 (including by way of merger or Investment) and in fact
      uses such Casualty Proceeds to rebuild or replace the damaged, destroyed
      or

                                      -56-
<PAGE>

      condemned assets or property subject to such Casualty Event or to acquire
      such other property or assets within 365 days following the receipt of
      such Casualty Proceeds, with the amount of such Casualty Proceeds unused
      after such 365 day period being applied to the Loans pursuant to Section
      3.1.2; provided further, however, that at any time when any Event of
      Default shall have occurred and be continuing or Casualty Proceeds not
      applied as provided above shall exceed $2,000,000, such Casualty Proceeds
      will be deposited in an account maintained with the Administrative Agent
      for disbursement at the request of the Borrower to pay for such
      rebuilding, replacement or acquisition.

            (f) On each date when any reduction in the Revolving Loan Commitment
      Amount shall become effective, the Borrower shall make a mandatory
      prepayment of Revolving Loans and (if necessary) Swing Line Loans and (if
      necessary) deposit with the Administrative Agent cash collateral for
      Letter of Credit Outstandings in an aggregate amount equal to the excess,
      if any, of the sum of (i) the aggregate outstanding principal amount of
      all Revolving Loans and Swing Line Loans and (ii) the aggregate amount of
      all Letter of Credit Outstandings over the Revolving Loan Commitment
      Amount as so reduced;

            (g) The Borrower shall, on the Stated Maturity Date and on each
      Quarterly Payment Date occurring during any period set forth below, make a
      scheduled repayment of the outstanding principal amount, if any, of Term-A
      Loans in an aggregate amount equal to the amount set forth below opposite
      such Stated Maturity Date or period, as applicable (as such amounts may
      have otherwise been reduced pursuant to this Agreement):

            (j) Following the prepayment in full of the Term Loans, on the date
      the Term Loans would otherwise have been required to be prepaid on account
      of any Net Disposition Proceeds, Net Debt Proceeds, Excess Cash Flow, Net
      Equity Proceeds or Casualty Proceeds, the Borrower shall first, prepay
      Revolving Loans and Swing Line Loans, and, second, deposit with the
      Administrative Agent cash collateral for Letter of Credit Outstandings, in
      an aggregate amount equal to the amount by which the Term Loans would
      otherwise have been required to be prepaid if Term Loans had been
      outstanding.

            (k) The Borrower shall, immediately upon any acceleration of the
      Stated Maturity Date of any Loans or Obligations pursuant to Section 8.2
      or Section 8.3, repay all outstanding Loans and other Obligations, unless,
      pursuant to Section 8.3, only a portion of all Loans and other Obligations
      are so accelerated (in which case the portion so accelerated shall be so
      prepaid).

                                      -58-
<PAGE>

      Each prepayment of any Loans made pursuant to this Section shall be
without premium or penalty, except as may be required by Section 4.4. No
prepayment of principal of any Revolving Loans or Swing Line Loans pursuant to
clause (a) or (j) of this Section 3.1.1 shall cause a reduction in the Revolving
Loan Commitment Amount or the Swing Line Loan Commitment Amount, as the case may
be.

      SECTION 3.1.2. Application. (a) Subject to clause (b) below, each
prepayment or repayment of principal of the Loans of any Tranche shall be
applied, to the extent of such prepayment or repayment, first, to the principal
amount thereof being maintained as Base Rate Loans, and second, to the principal
amount thereof being maintained as LIBO Rate Loans.

      (b) Each prepayment of Term Loans made pursuant to clauses (a), (b), (c),
(d) and (e) of Section 3.1.1 shall be applied, (i) on a pro rata basis, to the
outstanding principal amount of all remaining Term-A Loans, Term-B Loans and
Term-C Loans and (ii) in respect of each Tranche of Term Loans, in direct order
of maturity of the remaining scheduled quarterly amortization payments in
respect thereof, until all such Term-A Loans, Term-B Loans and Term-C Loans have
been paid in full (provided, however, that if the Borrower at any time elects in
writing, in its sole discretion, to permit any Lender that has Term-B Loans or
Term-C Loans to decline to have such Loans prepaid, then any Lender having
Term-B Loans or Term-C Loans outstanding may, by delivering a notice to the
Agents at least one Business Day prior to the date that such prepayment is to be
made, decline to have such Loans prepaid with the amounts set forth above, in
which case 50% of the amounts that would have been applied to a prepayment of
such Lender's Term-B Loans or Term-C Loans, as the case may be, shall instead be
applied to a prepayment of the Term-A Loans (until paid in full), with the
balance being retained by the Borrower).

      SECTION 3.2. Interest Provisions. Interest on the outstanding principal
amount of the Loans shall accrue and be payable in accordance with this Section
3.2.

      SECTION 3.2.1. Rates. (a) Each Base Rate Loan shall accrue interest on the
unpaid principal amount thereof for each day from and including the day upon
which such Loan was made or converted to a Base Rate Loan to but excluding the
date such Loan is repaid or converted to a LIBO Rate Loan at a rate per annum
equal to the sum of the Alternate Base Rate for such day plus the Applicable
Margin for such Loan on such day.

      (b) Each LIBO Rate Loan shall accrue interest on the unpaid principal
amount thereof for each day during each Interest Period applicable thereto at a
rate per annum equal to the sum of the LIBO Rate (Reserve Adjusted) for such
Interest Period plus the Applicable Margin for such Loan on such day.

All LIBO Rate Loans shall bear interest from and including the first day of the
applicable Interest Period to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such LIBO Rate Loan.

      SECTION 3.2.2. Post-Maturity Rates. After the date any principal amount of
any Loan shall have become due and payable (whether on the applicable Stated
Maturity Date, upon acceleration or otherwise), or any other monetary Obligation
(other than overdue Reimbursement Obligations which shall bear interest as
provided in Section 2.6.2) of the Borrower shall have become due and payable,
the Borrower shall pay, but only to the extent permitted by law, interest (after
as well as before judgment) on such amounts at a rate per annum equal to (a) in
the case of any overdue principal of Loans, overdue interest thereon, overdue
commitment fees or other overdue amounts in respect of Loans or other
obligations (or the related Commitments) under a particular Tranche, the rate
that would otherwise be applicable to Base Rate Loans under such Tranche
pursuant to Section 3.2.1 plus 2% and (b) in the case of other overdue monetary
Obligations, the rate that would otherwise be applicable to Revolving Loans that
were Base Rate Loans plus 2%.

      SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be
payable, without duplication:

            (a) on the Stated Maturity Date therefor;

            (b) in the case of a LIBO Rate Loan, on the date of any payment or
      prepayment, in whole or in part, of principal outstanding on such Loan, to
      the extent of the unpaid interest accrued through such date on the
      principal so paid or prepaid;

            (c) with respect to Base Rate Loans, on each Quarterly Payment Date
      occurring after the Amendment Effective Date;

            (d) with respect to LIBO Rate Loans, on the last day of each
      applicable Interest Period (and, if such Interest Period shall exceed
      three months, at intervals of three months after the first day of such
      Interest Period); and

            (e) on that portion of any Loans the Stated Maturity Date of which
      is accelerated pursuant to Section 8.2 or Section 8.3, immediately upon
      such acceleration.

Interest accrued on Loans, Reimbursement Obligations or other monetary
Obligations arising under this Agreement or any other Loan Document after the
date such amount is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise) shall be payable upon demand.

      SECTION 3.3. Fees. The Borrower agrees to pay the fees set forth in this
Section 3.3. All such fees shall be non-refundable.

      SECTION 3.3.1. Commitment Fee. The Borrower agrees to pay to the
Administrative Agent for the account of each Lender that has a Revolving Loan
Commitment (under the Existing Credit Agreement or hereunder), for each day
during the period (including any portion thereof

                                      -60-
<PAGE>

when any of the Lenders' Revolving Loan Commitments are suspended by reason of
the Borrower's inability to satisfy any condition of Article V) commencing on
the Closing Date and continuing to but excluding the Revolving Loan Commitment
Termination Date, a commitment fee on such Lender's Percentage of the unused
portion, whether or not then available, of the Revolving Loan Commitment Amount
(net of Letter of Credit Outstandings) for such day at a rate per annum equal to
the Applicable Commitment Fee for such day. Such commitment fee shall be payable
by the Borrower in arrears on each Quarterly Payment Date, commencing with the
first such day following the Closing Date, and on the Revolving Loan Commitment
Termination Date. The making of Swing Line Loans shall not constitute usage of
the Revolving Loan Commitment with respect to the calculation of commitment fees
to be paid by the Borrower to the Lenders. Payments by the Borrower to the Swing
Line Lender in respect of accrued interest on Swing Line Loans shall be net of
the commitment fee payable in respect of the Swing Line Lender's Revolving Loan
Commitment.

      SECTION 3.3.2. Administrative Agent Fee. The Borrower agrees to pay an
administration fee to the Administrative Agent, for its own account, in the
amount and at such times set forth in the Administrative Agent Fee Letter.

      SECTION 3.3.3. Letter of Credit Fee. The Borrower agrees to pay to the
Administrative Agent, for the pro rata account of the applicable Issuer and each
other Lender that has a Revolving Loan Commitment (under the Existing Credit
Agreement or hereunder), a letter of credit fee for each day on which there
shall be any Letters of Credit outstanding in an amount equal to (i) with
respect to each standby Letter of Credit, a rate per annum equal to the then
Applicable Margin for Revolving Loans maintained as LIBO Rate Loans, multiplied
by the Stated Amount of each such Letter of Credit; and (ii) with respect to
each documentary Letter of Credit, 1.25% per annum multiplied by the Stated
Amount of each such Letter of Credit, such fees being payable quarterly in
arrears on each Quarterly Payment Date. The Borrower further agrees to pay to
the applicable Issuer an issuance fee at the rates and on such dates agreed to
between the Borrower and such Issuer.

                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

      SECTION 4.1. LIBO Rate Lending Unlawful. If any Lender shall determine
(which determination shall, in the absence of manifest error, upon notice
thereof to the Borrower and the Lenders, be conclusive and binding on the
Borrower) that the introduction of or any change in or in the interpretation of
any law, in each case after the date upon which such Lender shall have become a
Lender under the Existing Credit Agreement or hereunder, makes it unlawful, or
any central bank or other governmental authority asserts, after such date, that
it is unlawful, for such Lender to make, continue or maintain any Loan as, or to
convert any Loan into, a LIBO Rate Loan, the obligations of such Lender to make,
continue, maintain or convert any Loans as or to

                                      -61-
<PAGE>

LIBO Rate Loans shall, upon such determination, forthwith be suspended until
such Lender shall notify the Administrative Agent that the circumstances causing
such suspension no longer exist (with the date of such notice being the
"Reinstatement Date"), and (i) all LIBO Rate Loans previously made by such
Lender shall automatically convert into Base Rate Loans at the end of the then
current Interest Periods with respect thereto or sooner, if required by such law
or assertion and (ii) all Loans thereafter made by such Lender and outstanding
prior to the Reinstatement Date shall be made as Base Rate Loans, with interest
thereon being payable on the same date that interest is payable with respect to
the corresponding Borrowing of LIBO Rate Loans made by Lenders not so affected.

      SECTION 4.2. Deposits Unavailable. If the Administrative Agent shall have
determined that (i) Dollar deposits in the relevant amount and for the relevant
Interest Period are not available to the Administrative Agent in its relevant
market, or (ii) by reason of circumstances affecting the Administrative Agent's
relevant market, adequate means do not exist for ascertaining the interest rate
applicable hereunder to LIBO Rate Loans, then, upon notice from the
Administrative Agent to the Borrower and the Lenders, the obligations of all
Lenders under Section 2.3 and Section 2.4 to make or continue any Loans as, or
to convert any Loans into, LIBO Rate Loans shall forthwith be suspended until
the Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

      SECTION 4.3. Increased LIBO Rate Loan Costs, etc. The Borrower agrees to
reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or of converting (or of its obligation to convert) any
Loans into, LIBO Rate Loans (excluding any amounts, whether or not constituting
Taxes, referred to in Section 4.6) arising as a result of any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority that occurs after the date upon which such
Lender became a Lender under the Existing Credit Agreement or hereunder. Such
Lender shall promptly notify the Administrative Agent and the Borrower in
writing of the occurrence of any such event, such notice to state, in reasonable
detail, the reasons therefor and the additional amount required fully to
compensate such Lender for such increased cost or reduced amount. Such
additional amounts shall be payable by the Borrower directly to such Lender
within five days of its receipt of such notice, and such notice shall, in the
absence of manifest error, be conclusive and binding on the Borrower.

      SECTION 4.4. Funding Losses. In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the principal amount of any Loan as, or to
convert any portion of the principal amount of any Loan into, a LIBO Rate Loan,
but excluding any loss of margin after the date of any such conversion,
repayment, prepayment or failure to borrow, continue or convert) as a result of
(i) any conversion

                                      -62-
<PAGE>

or repayment or prepayment of the principal amount of any LIBO Rate Loans on a
date other than the scheduled last day of the Interest Period applicable
thereto, whether pursuant to Section 3.1 or otherwise, (ii) any Loans not being
borrowed as LIBO Rate Loans in accordance with the Borrowing Request therefor,
or (iii) any Loans not being continued as, or converted into, LIBO Rate Loans in
accordance with the Continuation/ Conversion Notice therefor, then, upon the
written notice of such Lender to the Borrower (with a copy to the Administrative
Agent), the Borrower shall, within five days of its receipt thereof, pay
directly to such Lender such amount as will (in the reasonable determination of
such Lender) reimburse such Lender for such loss or expense. Such written notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on the Borrower.

      SECTION 4.5. Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority, in each case occurring after the applicable
Lender became a Lender under the Existing Credit Agreement or hereunder, affects
or would affect the amount of capital required or expected to be maintained by
any Lender or any Person controlling such Lender, and such Lender determines (in
its sole and absolute discretion) that the rate of return on its or such
controlling Person's capital as a consequence of its Commitments, participation
in Letters of Credit or the Loans made by such Lender is reduced to a level
below that which such Lender or such controlling Person could have achieved but
for the occurrence of any such circumstance, then, in any such case upon notice
from time to time by such Lender to the Borrower, the Borrower shall immediately
pay directly to such Lender additional amounts sufficient to compensate such
Lender or such controlling Person for such reduction in rate of return. A
statement of such Lender as to any such additional amount or amounts (including
calculations thereof in reasonable detail) shall, in the absence of manifest
error, be conclusive and binding on the Borrower. In determining such amount,
such Lender may use any method of averaging and attribution that it (in its sole
and absolute discretion) shall deem applicable; provided, that such Lender may
not impose materially greater costs on the Borrower than on other similarly
situated borrowers by virtue of any such averaging or attribution method.

      SECTION 4.6. Taxes. (a) All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder or under any
other Loan Document (including Reimbursement Obligations, fees and expenses)
shall be made free and clear of and without deduction for any present or future
income, excise, stamp or franchise taxes and other taxes, fees, duties,
withholdings or other charges of any nature whatsoever imposed by any taxing
authority from or through which payments originate or are made or deemed made by
or to the Borrower, but excluding (i) any income, excise, stamp or franchise
taxes and other similar taxes, fees, duties, withholdings or other charges
imposed on any Lender or either of the Agents by a jurisdiction under the laws
of which such Lender or Agent is organized or in which its principal executive
office is located, or otherwise as a result of a present or former connection
between the applicable lending office (or office through which it performs any
of its actions as Lender or Agent) of such Lender or Agent and the jurisdiction
of the governmental authority imposing such tax or any

                                      -63-
<PAGE>

political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from such Agent or such Lender having executed,
delivered or performed its obligations or received a payment under, or taken any
action to enforce, this Agreement and any Note) or (ii) any income, excise,
stamp or franchise taxes and other similar taxes, fees, duties, withholdings or
other charges to the extent that they are in effect and would apply as of the
date any Person becomes a Lender or Assignee Lender under the Existing Credit
Agreement or hereunder, or as of the date that any Lender changes its applicable
lending office, to the extent such taxes become applicable as a result of such
change (other than a change in an applicable lending office made pursuant to
Section 4.10 below) (such non-excluded items being called "Taxes"). In the event
that any withholding or deduction from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule or regulation, then the Borrower will (i) pay directly to the relevant
taxing authority the full amount required to be so withheld or deducted, (ii)
promptly forward to the Administrative Agent an official receipt or other
documentation available to the Borrower reasonably satisfactory to the
Administrative Agent evidencing such payment to such authority, and (iii) pay to
the Administrative Agent for the account of the Lenders such additional amount
or amounts as is necessary to ensure that the net amount actually received by
each Lender will equal the full amount such Lender would have received had no
such withholding or deduction been required, provided, however, that the
Borrower shall not be required to pay any such additional amounts in respect of
amounts payable to any Lender that is not organized under the laws of the United
States or a state thereof to the extent that the related tax is imposed (or an
exemption therefrom is not available) as a result of such Lender or Agent
failing to comply with the requirements of clause (b) of Section 4.6.

      Moreover, if any Taxes are directly asserted against either of the Agents
or any Lender with respect to any payment received by such Agents or such Lender
hereunder, such Agents or such Lender may pay such Taxes and the Borrower will
promptly pay to such Person such additional amount (including any penalties,
interest or expenses) as is necessary in order that the net amount received by
such Person (including any Taxes on such additional amount) shall equal the
amount of such Taxes paid by such Person; provided, however, that the Borrower
shall not be obligated to make payment to the Lenders or the Agents (as the case
may be) pursuant to this sentence in respect of penalties or interest
attributable to any Taxes, if written demand therefor has not been made by such
Lenders or the Agents within 60 days from the date on which such Lenders or the
Agents knew of the imposition of Taxes by the relevant taxing authority or for
any additional imposition which may arise from the failure of the Lenders or the
Agents to apply payments in accordance with the tax law after the Borrower has
made the payments required hereunder; provided, further, that the Borrower shall
not be required to pay any such additional amounts in respect of any amounts
payable to any Lender or any Agent (as the case may be) that is not organized
under the laws of the United States or a state thereof to the extent the related
Tax is imposed as a result of such Lender failing to comply with the
requirements of clause (b) of Section 4.6. After the Lenders or the Agents (as
the case may be) learn of the imposition of Taxes, such Lenders and the Agents
will act in good faith to notify the Borrower of its obligations hereunder as
soon as reasonably possible.

                                      -64-
<PAGE>

      If the Borrower fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent, for the account of the
respective Lenders, the required receipts or other required documentary
evidence, the Borrower shall indemnify the Lenders for any incremental Taxes,
interest or penalties that may become payable by any Lender as a result of any
such failure.

      (b) Each Non-U.S. Lender shall, (i) on or prior to the date of the
execution and delivery of this Agreement, in the case of each Lender listed on
the signature pages hereof, or, in the case of an Assignee Lender, on or prior
to the date it becomes a Lender, execute and deliver to the Borrower and the
Administrative Agent, two or more (as the Borrower or the Agents may reasonably
request) United States Internal Revenue Service Forms W-8ECI or Forms W-8BEN (or
successor forms) establishing the Lender's exemption from United States federal
withholding tax, or, solely if such Lender is claiming exemption from United
States withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest", United States Internal Revenue Service
Forms W-8BEN and a certificate signed by a duly authorized officer of such
Lender representing that such Lender is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code, or such other forms or documents (or successor
forms or documents), appropriately completed, establishing that payments to such
Lender are exempt from withholding or deduction of United States federal
withholding taxes; and (ii) deliver to the Borrower and the Administrative Agent
two further copies of any such form or documents on or before the date that any
such form or document expires or becomes obsolete and after the occurrence of
any event requiring a change in the most recent such form or document previously
delivered by it to the Borrower. Each Lender and each Agent agrees, to the
extent reasonable and without material cost to it, to provide to the Borrower
and the Administrative Agent such other applicable forms or certificates as
would reduce or eliminate any Tax otherwise applicable.

      (c) If the Borrower determines in good faith that a reasonable basis
exists for contesting the imposition of a Tax with respect to a Lender or either
of the Agents, the relevant Lender or Agent, as the case may be, shall cooperate
with the Borrower in challenging such Tax at the Borrower's expense if requested
by the Borrower; provided, however, that nothing in this Section 4.6 shall
require any Lender or Agent to submit to the Borrower or any Person any tax
returns or any part thereof, or to prepare or file any tax returns other than as
such Lender or Agent in its sole discretion shall determine.

      (d) If a Lender or an Agent shall receive a refund (including any offset
or credits from a taxing authority (as a result of any error in the imposition
of Taxes by such taxing authority) of any Taxes paid by the Borrower pursuant to
subsection 4.6(a) above, such Lender or such Agent (as the case may be) shall
promptly pay the Borrower the amount so received, with interest from the taxing
authority with respect to such refund, net of any tax liability incurred by such
Lender or Agent that is attributable to the receipt of such refund and such
interest.

      (e) Each Lender and each Agent agrees, to the extent reasonable and
without material cost to it, to cooperate with the Borrower to minimize any
amounts payable by the Borrower

                                      -65-
<PAGE>

under this Section 4.6; provided, however, that nothing in this Section 4.6
shall require any Lender or Agent to take any action which, in the sole
discretion of such Lender or Agent, is inconsistent with its internal policy and
legal and regulatory restrictions.

      (f) If the Borrower is required to pay additional amounts to or for the
account of any Lender or Agent pursuant to clause (a) of this Section 4.6 as a
result of a change of law occurring after the Closing Date, then such Lender or
Agent, at the request of the Borrower, will change the jurisdiction of its
applicable lending office (or office through which it performs any of its
actions as Agent) if such change (i) would eliminate or reduce any such
additional payment which may thereafter accrue and (ii) is not, in the good
faith determination of such Lender or Agent, otherwise disadvantageous to such
Lender or Agent.

      SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly
provided, all payments by or on behalf of the Borrower pursuant to this
Agreement or any other Loan Document shall be made by the Borrower to the
Administrative Agent for the pro rata account of the Lenders, Agents or Lead
Arranger, as applicable, entitled to receive such payment. All such payments
required to be made to the Administrative Agent shall be made, without setoff,
deduction or counterclaim, not later than 11:00 a.m., Designated City time, on
the date due, in same day or immediately available funds, to such account as the
Administrative Agent shall specify from time to time by notice to the Borrower.
Funds received after that time shall be deemed to have been received by the
Administrative Agent on the next succeeding Business Day. The Administrative
Agent shall promptly remit in same day funds to each Lender, Agent or Lead
Arranger, as the case may be, its share, if any, of such payments received by
the Administrative Agent for the account of such Lender, Agent or Lead Arranger,
as the case may be. All interest and fees shall be computed on the basis of the
actual number of days (including the first day but excluding the last day)
occurring during the period for which such interest or fee is payable over a
year comprised of 360 days (or, in the case of interest on a Base Rate Loan, 365
days or, if appropriate, 366 days). Whenever any payment to be made shall
otherwise be due on a day which is not a Business Day, such payment shall
(except as otherwise required by clause (i) of the definition of the term
"Interest Period") be made on the next succeeding Business Day and such
extension of time shall be included in computing interest and fees, if any, in
connection with such payment.

      SECTION 4.8. Sharing of Payments. If any Lender shall obtain any payment
or other recovery (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Loan or Reimbursement Obligation (other than
pursuant to the terms of Sections 4.3, 4.4 and 4.5) in excess of its pro rata
share of payments then or therewith obtained by all Lenders entitled thereto,
such Lender shall purchase from the other Lenders such participation in the
Credit Extensions made by them as shall be necessary to cause such purchasing
Lender to share the excess payment or other recovery ratably with each of them;
provided, however, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing Lender, the purchase shall
be rescinded and each Lender which has sold a participation to the purchasing
Lender shall repay to the purchasing Lender the purchase price to the ratable
extent of

                                      -66-
<PAGE>

such recovery together with an amount equal to such selling Lender's ratable
share (according to the proportion of (i) the amount of such selling Lender's
required repayment to the purchasing Lender in respect of such recovery, to (ii)
the total amount so recovered from the purchasing Lender) of any interest or
other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section may, to the fullest
extent permitted by law, exercise all its rights of payment (including pursuant
to Section 4.9) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation. If
under any applicable bankruptcy, insolvency or other similar law, any Lender
receives a secured claim in lieu of a setoff to which this Section applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders entitled
under this Section to share in the benefits of any recovery on such secured
claim.

      SECTION 4.9. Setoff. Each Lender shall, upon the occurrence of any Event
of Default described in clauses (b) through (d) of Section 8.1.9 with respect to
any Obligor (other than a Subsidiary that is not a Material Subsidiary) or, with
the consent of the Required Lenders, upon the occurrence of any other Event of
Default, to the fullest extent permitted by law, have the right to appropriate
and apply to the payment of the Obligations then due to it, and (as security for
such Obligations) the Borrower hereby grants to each Lender a continuing
security interest in, any and all balances, credits, deposits, accounts or
moneys of the Borrower then or thereafter maintained with or otherwise held by
such Lender; provided, however, that any such appropriation and application
shall be subject to the provisions of Section 4.8. Each Lender agrees promptly
to notify the Borrower and the Administrative Agent after any such setoff and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such setoff and application. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff under applicable law or otherwise)
which such Lender may have.

      SECTION 4.10. Mitigation. Each Lender agrees that if it makes any demand
for payment under Sections 4.3, 4.4, 4.5, or 4.6, or if any adoption or change
of the type described in Section 4.1 shall occur with respect to it, it will use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, as
determined in its sole discretion) to designate a different lending office if
the making of such a designation would reduce or obviate the need for the
Borrower to make payments under Section 4.3, 4.4, 4.5, or 4.6, or would
eliminate or reduce the effect of any adoption or change described in Section
4.1.

      SECTION 4.11. Replacement of Lenders. Each Lender hereby severally agrees
as set forth in this Section. If any Lender (a "Subject Lender") (i) makes
demand upon the Borrower for (or if the Borrower is otherwise required to pay)
amounts pursuant to Section 4.3, 4.5 or 4.6, (ii) gives notice pursuant to
Section 4.1 requiring a conversion of such Subject Lender's LIBO Rate Loans to
Base Rate Loans or any change in the basis upon which interest is to accrue in

                                      -67-
<PAGE>

respect of such Subject Lender's LIBO Rate Loans or suspending such Lender's
obligation to make Loans as, or to convert Loans into, LIBO Rate Loans, (iii)
becomes a Non-Consenting Lender or (iv) becomes a Non-Funding Lender, the
Borrower may, within 180 days of receipt by the Borrower of such demand or
notice (or the occurrence of such other event causing the Borrower to be
required to pay such compensation) or within 180 days of such Lender becoming a
Non-Consenting Lender or a Non-Funding Lender, as the case may be, give notice
(a "Replacement Notice") in writing to the Agents and such Subject Lender of its
intention to replace such Subject Lender with a financial institution (a
"Replacement Lender") designated in such Replacement Notice. If the Agents
shall, in the exercise of their reasonable discretion and within 30 days of
their receipt of such Replacement Notice, notify the Borrower and such Subject
Lender in writing that the designated financial institution is satisfactory to
the Agents (such consent not being required where the Replacement Lender is
already a Lender), then such Subject Lender shall, subject to the payment of any
amounts due pursuant to Section 4.4, assign, in accordance with Section 10.11.1,
all of its Commitments, Loans and other rights and obligations under this
Agreement and all other Loan Documents (including Reimbursement Obligations) to
such designated financial institution; provided, however, that (i) such
assignment shall be without recourse, representation or warranty and shall be on
terms and conditions reasonably satisfactory to such Subject Lender and such
designated financial institution and (ii) the purchase price paid by such
designated financial institution shall be in the amount of such Subject Lender's
Loans and its Percentage in respect of any Revolving Loan Commitment under which
there are outstanding Reimbursement Obligations of such Reimbursement
Obligation, together with all accrued and unpaid interest and fees in respect
thereof, plus all other amounts (including the amounts demanded and unreimbursed
under Sections 4.3, 4.5 and 4.6), owing to such Subject Lender hereunder. Upon
the effective date of an assignment described above, the designated financial
institution or Replacement Lender shall become a "Lender" for all purposes under
this Agreement and the other Loan Documents.

302(f) of ERISA, which, in either case, is reasonably expected to lead to a
liability to such Pension Plan in excess of $5,000,000. No condition exists or
event or transaction has occurred with respect to any Pension Plan which could
reasonably be expected to result in the incurrence by the Borrower or any member
of the Controlled Group of any material liability, fine or penalty other than
such condition, event or transaction which would not reasonably be expected to

Benefit Plans") of the Disclosure Schedule or otherwise approved by the Agents

the last financial statement the Borrower has not increased any contingent
liability with respect to any post-retirement benefit under a Welfare Plan,
other than liability for continuation coverage described in Part 6 of Subtitle B
of Title I of ERISA, except as would not have a Material Adverse Effect.

Agents, the Lead Arranger, the Issuers or any Lender will be, taken as a whole,
true and accurate in every material respect on the date as of which such
information is dated or certified and such information is not, or shall not be,

necessary to make such information not materially misleading.

      Any term or provision of this Section to the contrary notwithstanding,
insofar as any of the factual information described above includes assumptions,
estimates, projections or opinions, no representation or warranty is made herein
with respect thereto; provided, however, that to the extent any such
assumptions, estimates, projections or opinions are based on factual matters,
the Borrower has reviewed such factual matters and nothing has come to its
attention in the context of such review which would lead it to believe that such
factual matters were not or are not true and correct in all material respects or

under the provisions of Section 548 of the Bankruptcy Code (11 U.S.C. ss.101 et
seq., as from time to time hereafter amended, and any successor or similar
statute) or any applicable state law respecting fraudulent transfers or
fraudulent conveyances. On the Closing Date, after giving effect to the Original
Transaction, the Borrower was Solvent.

      (b) The New Transaction (including, among other things, the incurrence of
the Term-C Loans by the Borrower and the application of the proceeds of the
Term-C Loans), will not

                                      -76-

involve or result in any fraudulent transfer or fraudulent conveyance under the

            (g) as soon as practicable after the controller, chief financial or
      accounting officer or the chief executive officer of the Borrower or a

      steps in writing to terminate any Pension Plan or (ii) the occurrence of
      any event with respect to a Pension Plan which, in the case of clause (i)
      or (ii), could reasonably be expected to result in a contribution to such
      Pension Plan by (or a liability to) the Borrower or a member of the
      Borrower's Controlled Group in excess of $5,000,000, (iii) the failure to
      make a required contribution to any Pension Plan if such failure is

cause each of its Subsidiaries to, comply in all material respects with all
applicable laws, rules, regulations and orders, such compliance to include (i)
except as permitted under Section 7.2.8, the maintenance and preservation of its
existence and qualification as a foreign business entity, except where the
failure to so qualify could not reasonably be expected to have a Material
Adverse Effect, and (ii) the payment, before the same become delinquent, of all
material taxes, assessments and governmental charges imposed upon it or upon its
property except to the extent being contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with GAAP shall have
been set aside on its books.

      SECTION 7.1.3. Maintenance of Properties. Except to the extent that the
failure to do so could not reasonably be expected to have a Material Adverse
Effect, the Borrower will, and will cause each of its Restricted Subsidiaries

wear and tear excepted), and make necessary and proper repairs, renewals and
replacements so that its business carried on in connection therewith may be
properly conducted at all times, unless the Borrower determines in good faith
that the continued maintenance of any of its properties is no longer
economically desirable.

Restricted Subsidiaries to, maintain or cause to be maintained with responsible
insurance companies insurance with respect to its properties and business
against such casualties and contingencies and of such types and in such amounts

endorsements as the Agents may reasonably request and will, upon request of the
Agents, furnish to the Agents and each Lender a certificate of an Authorized
Officer of the Borrower setting forth the nature and extent of all insurance
maintained by the Borrower and its Restricted Subsidiaries in accordance with
this Section.

      SECTION 7.1.5. Books and Records. The Borrower will, and will cause each
of its Restricted Subsidiaries to, keep books and records which accurately
reflect in all material respects all of its business affairs and transactions
and permit the Agents, the Issuers and each Lender or any of their respective
representatives, at reasonable times and intervals, and upon reasonable notice,
but, unless an Event of Default shall have occurred and be continuing, not more
frequently than once in each Fiscal Year, to visit its business offices, to
discuss its financial matters with its officers and, after notice to the
Borrower and provision of an opportunity for the Borrower to participate in such
discussion, its independent public accountants (and the Borrower hereby
authorizes such independent public accountants to discuss the Borrower's
financial matters with each Issuer and each Lender or its representatives,
whether or not any representative of the Borrower is present so long as the
Borrower has been afforded a reasonable opportunity to be present) and to
examine, and to photocopy extracts from, any of its books or other financial
records. The cost and expense of each such visit shall be borne by the

      the terms of this clause could not reasonably be expected to have a
      Material Adverse Effect;

            (b) promptly notify the Agents and provide copies of all written
      claims, complaints, notices or inquiries relating to the condition of its
      facilities and properties which relate to environmental matters or
      compliance with Environmental Laws which would have, or would reasonably
      be expected to have, a Material Adverse Effect, and promptly cure and have
      dismissed with prejudice any material actions and proceedings relating to
      compliance with Environmental Laws, except to the extent being diligently
      contested in good faith by appropriate proceedings and for which adequate
      reserves in accordance with GAAP have been set aside on its books; and

      SECTION 7.1.7. Future Subsidiaries. Upon any Person becoming, after the

Subsidiary or a Future Pledged Foreign Subsidiary, the Borrower shall notify the
Agents of such acquisition, and

            (a) the Borrower shall promptly cause such U.S. Subsidiary (other
      than (x) CRL Transactions Co., Inc., (y) until the PAIC Trigger Date, each
      of PAIC and each of its Subsidiaries unless such Person is merged into the
      Borrower as permitted under Section 7.2.8(a) prior to the PAIC Trigger
      Date, in which case the provisions of this clause (a) shall no longer
      apply to such Person and (z) until the Primedica Trigger Date, each of
      Primedica and each of its Subsidiaries unless such Person is merged into
      the Borrower as permitted under Section 7.2.8(a) prior to the Primedica
      Trigger Date, in which case the provisions of this clause (a) shall no
      longer apply to such Person) to execute and deliver to the Administrative
      Agent, with counterparts for each Lender, a Subsidiary Guaranty (or a
      supplement thereto) and a supplement to the Subsidiary Pledge and Security
      Agreement (and, if such U.S. Subsidiary owns any real property, to the
      extent required by clause (b) of Section 7.1.8, a Mortgage), together with
      UCC financing statements (form UCC-1) executed and delivered by such U.S.
      Subsidiary naming such U.S. Subsidiary as the debtor and the
      Administrative Agent as the secured party, or other similar instruments or
      documents, in appropriate form for filing under the UCC and any other
      applicable recording statutes, in the case of real property, of all
      jurisdictions as may be necessary or, in the reasonable opinion of the
      Administrative Agent, desirable to perfect the security interest of the
      Administrative Agent pursuant to the Subsidiary Pledge and Security
      Agreement or a Mortgage, as the case may be (other than the perfection of
      security interests in motor vehicles); and

            (b) the Borrower shall promptly deliver, or cause to be delivered,
      to the Administrative Agent under a Pledge Agreement (as supplemented, if
      necessary, by a Foreign Pledge Agreement or other supplement thereto)
      certificates (if any) representing all of the issued and outstanding
      shares of Capital Stock of such Subsidiary owned by the Borrower or any
      Restricted Subsidiary of the Borrower that is a U.S. Subsidiary (other
      than (x) until the PAIC Trigger Date, each of PAIC and each of its
      Subsidiaries unless such Person is merged into the Borrower as permitted
      under Section 7.2.8(a) prior to the PAIC Trigger Date and (y) until the
      Primedica Trigger Date, each of Primedica and each of its Subsidiaries
      unless such Person is merged into the Borrower as permitted under Section
      7.2.8(a) prior to the Primedica Trigger Date, which in either such case
      the provisions of this clause (b) shall no longer apply to such Person),
      as the case may be, along with undated powers of transfer for such
      certificates, executed in blank, or, if any

                                      -81-

      securities subject thereto are uncertificated securities or are held
      through a securities intermediary, the Administrative Agent shall have
      obtained "control" (as defined in the UCC applicable to the perfection of
      such securities) over such securities, or other appropriate steps shall
      have been taken under applicable law resulting in the perfection and
      "control" (as defined in the UCC) of the security interest granted in
      favor of the Administrative Agent pursuant to the terms of a Pledge
      Agreement,

      together, in each case, with such opinions, in form and substance and from
counsel satisfactory to the Agents, as the Agents may reasonably require;
provided, however, that notwithstanding the foregoing, no Foreign Subsidiary
shall be required to execute and deliver a Mortgage or a supplement to the
Subsidiary Pledge and Security Agreement, nor will the Borrower or any U.S.
Subsidiary of the Borrower be required to deliver in pledge pursuant to a Pledge
Agreement in excess of 65% of the Voting Stock of a Foreign Subsidiary; provided
further, however, that subject to the immediately preceding proviso, the
Borrower shall be required to pledge for the benefit of the Lenders, as soon as
reasonably practicable, only those shares of Capital Stock which it owns of
Charles River Japan other than those shares which are required to be pledged to
Ajinomoto Co., Inc. ("Ajinomoto") pursuant to its agreement to pay Ajinomoto 1.4
billion Yen over a three year period to acquire an additional 16% of Charles
River Japan.

      SECTION 7.1.8. Future Leased Property and Future Acquisitions of Real
Property; Future Acquisition of Other Property.

            (a) Prior to entering into any new lease of real property or
      renewing any existing lease of real property following the Closing Date,
      the Borrower shall, and shall cause each of its U.S. Subsidiaries that are
      Restricted Subsidiaries to, use its (and their) best efforts (which shall
      not require the expenditure of cash or the making of any material
      concessions under the relevant lease) to deliver to the Administrative
      Agent a Waiver executed by the lessor of any real property that is to be
      leased by the Borrower or such U.S. Subsidiary for a term in excess of one
      year in any state which by statute grants such lessor a "landlord's" (or
      similar) Lien which is superior to the Administrative Agent's, to the
      extent the value of any personal property of the Borrower or its U.S.
      Subsidiaries that are Restricted Subsidiaries to be held at such leased
      property exceeds (or it is anticipated that the value of such personal
      property will, at any point in time during the term of such leasehold
      term, exceed) $3,000,000.

            (b) In the event that the Borrower or any of its U.S. Subsidiaries
      that are Restricted Subsidiaries shall acquire any real property (other
      than any Primedica Mortgaged Facility) having a value as determined in
      good faith by the Administrative Agent in excess of $2,000,000 in the
      aggregate, the Borrower or the applicable U.S. Subsidiary shall, promptly
      after such acquisition, execute a Mortgage in favor of the Administrative
      Agent, as mortgagee for the ratable benefit of the Lenders, and provide
      the Administrative Agent with (i) evidence of the completion (or
      satisfactory arrangements for the completion) of all recordings and
      filings of such Mortgage as may be necessary or, in

                                      -82-
<PAGE>

      the reasonable opinion of the Administrative Agent, desirable effectively
      to create a valid, perfected, first priority Lien, subject to Liens
      permitted by Section 7.2.3, against the properties purported to be covered
      thereby, (ii) mortgagee's title insurance policies in favor of the
      Administrative Agent, as mortgagee for the ratable benefit of the Lenders,
      in amounts and in form and substance and issued by insurers, in each case
      reasonably satisfactory to the Agents, with respect to the property
      purported to be covered by such Mortgage, insuring that title to such
      property is indefeasible and that the interests created by the Mortgage
      constitute valid first Liens thereon free and clear of all defects and
      encumbrances other than as permitted by Section 7.2.3 or as approved by
      the Agents, and such policies shall also include, to the extent available,
      a revolving credit endorsement and such other endorsements as the Agents
      shall reasonably request and shall be accompanied by evidence of the
      payment in full of all premiums thereon, and (iii) such other approvals,
      opinions, or documents as the Agents may reasonably request; provided,
      however, that the provisions of this clause (b) shall not apply with
      respect to any properties owned or acquired by (A) any of PAIC or any of
      its Subsidiaries until the PAIC Trigger Date unless such Person is merged
      into the Borrower as permitted under Section 7.2.8(a) prior to the PAIC
      Trigger Date or (B) any of Primedica or any of its Subsidiaries until the
      Primedica Trigger Date unless such Person is merged into the Borrower as
      permitted under Section 7.2.8(a) prior to the Primedica Trigger Date,
      which in either such case the provisions of this clause (b) shall no
      longer apply to such Person.

            (c) In accordance with the terms and provisions of the Pledge
      Agreements, the Borrower and each U.S. Subsidiary that is a Restricted
      Subsidiary shall provide the Agents with evidence of all recordings and
      filings as may be necessary or, in the reasonable opinion of the
      Administrative Agent, desirable to create a valid, perfected first
      priority Lien, subject to the Liens permitted by Section 7.2.3, against
      all property acquired after the Closing Date (excluding motor vehicles,
      leases of real property and (except to the extent required under clause
      (b) of this Section 7.1.8) fee interests in real property); provided,
      however, that the provisions of this clause (c) shall not apply with
      respect to any such property owned or acquired by (x) any of PAIC or any
      of its Subsidiaries until the PAIC Trigger Date unless such Person is
      merged into the Borrower as permitted under Section 7.2.8(a) prior to the
      PAIC Trigger Date or (x) any of Primedica or any of its Subsidiaries until
      the Primedica Trigger Date unless such Person is merged into the Borrower
      as permitted under Section 7.2.8(a) prior to the Primedica Trigger Date,
      which in either such case case the provisions of this clause (c) shall no
      longer apply to such Person.

      SECTION 7.1.9. Use of Proceeds, etc. The Borrower shall

            (a) apply the proceeds of the Loans

                  (i) in the case of the Existing Term Loans and Existing
            Revolving Loans in an aggregate principal amount not in excess of
            $2,000,000 made on the Closing

            Date, to pay, in part, the cash portion of the obligations of Holdco
            in connection with the Original Transaction and to pay the
            transaction fees and expenses associated with the Original
            Transaction (directly or by paying the Subco Dividend); provided,
            that the aggregate amount of such transaction fees and expenses
            shall not exceed $20,000,000;

                  (ii) in the case of the Term-C Loans, to pay, in part, a
            portion of the purchase price and the Primedica Transaction Fees and
            Expenses due in connection with the consummation of the New
            Transaction; provided, that the aggregate amount of the Primedica
            Transaction Fees and Expenses shall not exceed $1,200,000; and

                  (iii) in the case of Revolving Loans (other than Existing
            Revolving Loans described in clause (a)(i) above) and Swing Line
            Loans, for working capital and general corporate purposes of the
            Borrower and its Subsidiaries; and

            (b) use Letters of Credit only for purposes of supporting working
      capital and general corporate purposes of the Borrower and its Restricted
      Subsidiaries.

      SECTION 7.1.10. Hedging Obligations. Within six months following the
Closing Date, the Administrative Agent shall have received evidence satisfactory
to it that the Borrower has entered into interest rate swap, cap, collar or
similar arrangements (including such Indebtedness accruing interest at a fixed
rate by its terms) designed to protect the Borrower against fluctuations in
interest rates with respect to at least 50% of the aggregate principal amount of
the Term Loans and the Senior Subordinated Notes for a period of at least three
years from the Closing Date, with terms reasonably satisfactory to the Borrower
and the Agents.

      SECTION 7.1.11. Year 2000 Compliance. The Borrower will promptly notify
the Administrative Agent in the event the Borrower discovers or determines that
any computer application (including those of its suppliers and vendors) that is
material to its or any of its Restricted Subsidiaries' businesses and operations
will not be Year 2000 compliant as of January 1, 2000, except to the extent that
such failure could not reasonably be expected to have a Material Adverse Effect.

      SECTION 7.2. Negative Covenants. The Borrower agrees with the Agents and
each Lender that, until the Termination Date has occurred, the Borrower will
perform the obligations set forth in this Section 7.2.

      SECTION 7.2.1. Business Activities. The Borrower will not, and will not
permit any of its Restricted Subsidiaries to, engage in any business activity,
except the business activities of the type in which the Borrower and its
Subsidiaries are engaged on the Closing Date (after giving effect to the
Original Transaction) and any businesses reasonably ancillary, incidental or
related thereto.

      satisfactory to the Agents which shall be duly executed and delivered to
      (and indorsed to the order of) the Administrative Agent in pledge pursuant
      to a Pledge Agreement and (2) in the case of any such Indebtedness owed by

      of the Borrower and its Restricted Subsidiaries, not to exceed an amount
      (the "Base Amount") equal to (i) (A) $17,500,000 in the case of the Fiscal
      Year ending December 31, 2000 and (B) $22,500,000 in the case of each
      Fiscal Year thereafter; plus (ii) an aggregate amount in addition to the
      Base Amount over the term of this Agreement equal to $25,000,000;
      provided, however, that, to the extent the Base Amount exceeds the
      aggregate amount of Capital Expenditures (other than amounts permitted to
      be made pursuant to clause (a)(ii) above or clause (b) below) actually
      made during such Fiscal Year, such excess amount (up to an aggregate of
      50% of the amount of the Base Amount for such Fiscal Year) may be carried
      forward to (but only to) the next succeeding Fiscal Year (any such amount
      to be certified by the Borrower to the Agents in the Compliance
      Certificate delivered for the last Fiscal Quarter of such Fiscal Year, and
      any such amount carried forward to a succeeding Fiscal Year shall be
      deemed to be used prior to the Borrower and its Restricted Subsidiaries
      using the Base Amount for such succeeding Fiscal Year, without giving
      effect to such carry-forward).

            (b) The parties acknowledge and agree that the permitted Capital
      Expenditure level set forth in clause (a) above shall be exclusive of (i)

      Restricted Subsidiaries, after the Closing Date and specifically
      identified in a certificate delivered by an Authorized Officer of the
      Borrower to the Agents on or about the time such capital contribution or
      equity issuance is made (but in any event prior to the time of the Capital
      Expenditure made with such capital contribution or equity issuance)
      (provided that, to the extent such cash capital contributions or any
      proceeds from such equity issuance constitute Net Equity Proceeds arising
      from the issuance by Holdco or the Borrower of their respective Capital
      Stock, only that portion of such Net Equity Proceeds which are not
      required to be applied as a prepayment pursuant to clause (d) of Section
      3.1.1 may be used for Capital Expenditures pursuant to this clause (b))
      and (ii) any portion of any acquisition that is permitted under Section
      7.2.5 (other than pursuant to clause (d) thereof) that is accounted for as
      a Capital Expenditure.

      SECTION 7.2.8. Consolidation, Merger, etc. The Borrower will not, and will
not permit any of its Restricted Subsidiaries to, liquidate or dissolve,
consolidate with, or merge into or with,

any other corporation, or purchase or otherwise acquire all or substantially all
of the assets of any Person (or of any division thereof), except

            (a) any such Restricted Subsidiary may liquidate or dissolve
      voluntarily into, and may merge with and into, the Borrower (so long as
      the Borrower is the surviving corporation of such combination or merger)
      or any other Restricted Subsidiary, and the assets or Capital Stock of any
      Restricted Subsidiary may be purchased or otherwise acquired by the
      Borrower or any other Restricted Subsidiary; provided, that
      notwithstanding the above, a Restricted Subsidiary may only liquidate or
      dissolve into, or merge with and into, another Restricted Subsidiary of
      the Borrower if, after giving effect to such combination or merger, the
      Borrower continues to own (directly or indirectly), and the Administrative
      Agent continues to have pledged to it pursuant to a Pledge Agreement, a
      percentage of the issued and outstanding shares of Capital Stock (on a
      fully diluted basis) of the Restricted Subsidiary surviving such
      combination or merger that is equal to or in excess of the percentage of
      the issued and outstanding shares of Capital Stock (on a fully diluted
      basis) of the Restricted Subsidiary that does not survive such combination
      or merger that was (immediately prior to the combination or merger) owned
      by the Borrower or pledged to the Administrative Agent;

            (b) so long as no Default has occurred and is continuing or would
      occur after giving effect thereto, the Borrower or any of its Restricted
      Subsidiaries may purchase all or substantially all of the assets of any
      Person (or any division thereof) not then a Restricted Subsidiary, or
      acquire such Person by merger, if permitted (without duplication) pursuant
      to Section 7.2.7 or clause (e), (f), (l), (o), (p), (q) or (r) of Section
      7.2.5;

            (c) the Borrower and its Restricted Subsidiaries may consummate the
      Original Transaction; and

            (d) the Borrower and its Restricted Subsidiaries may liquidate or
      dissolve Charles River China and Charles River Mexico and may take any
      action described in clause (b) or (d) of Section 8.1.9.

contribute or otherwise convey, or grant options, warrants or other rights with
respect to, all or any part of its assets, whether now owned or hereafter
acquired (including accounts receivable and Capital Stock of Restricted
Subsidiaries) to any Person, unless:

            (a) such sale, transfer, lease, contribution or conveyance of such
      assets is (i) in the ordinary course of its business (and does not
      constitute a sale, transfer, lease, contribution or other conveyance of
      all or a substantial part of the Borrower's and its Restricted
      Subsidiaries' assets, taken as a whole) or is of obsolete or worn out
      property,

      its Restricted Subsidiaries or between Restricted Subsidiaries of the
      Borrower;

            (b) such sale, transfer, lease, contribution or conveyance
      constitutes (i) an Investment permitted under Section 7.2.5, (ii) a Lien
      permitted under Section 7.2.3, or (iii) a Restricted Payment permitted
      under Section 7.2.6;

            (c) (i) such sale, transfer, lease, contribution or conveyance of
      such assets is for fair market value and the consideration consists of no
      less than 75% in cash or is a Lien permitted under Section 7.2.3(h)(iii),
      (ii) the Net Disposition Proceeds received from such assets, together with
      the Net Disposition Proceeds of all other assets sold, transferred,
      leased, contributed or conveyed pursuant to this clause (c) since the
      Closing Date (but excluding any Net Disposition Proceeds received from the

      Subsidiaries of the two islands in the Florida Keys that were previously
      used by them to study a non-human primate breeding colony and the
      Primedica Toxicology Facility), does not exceed (individually or in the
      aggregate) $20,000,000 over the term of this Agreement and (iii) an amount
      equal to the Net Disposition Proceeds generated from such sale, transfer,

      business, but only in connection with the compromise or collection
      thereof.

      SECTION 7.2.10. Modification of Certain Agreements. Without the prior
written consent of the Required Lenders, the Borrower will not, and will not
permit any of its Restricted Subsidiaries to, consent to any amendment,
supplement, amendment and restatement, waiver or other modification of any of
the terms or provisions contained in, or applicable to, any Senior Subordinated
Debt Document or the PAIC Subordinated Convertible Note (including any agreement
or indenture related thereto or to the Subordinated Debt Issuance or the
issuance of the PAIC Subordinated Convertible Note) or any Material Document or
any schedules, exhibits or agreements related thereto (the "Restricted
Agreements"), in each case which would materially adversely affect the rights or
remedies of the Lenders, or the Borrower's or any other Obligor's ability to
perform hereunder or under any Loan Document or which would (a) increase the
cash consideration payable in respect of the Recapitalization, (b), in the case

Senior Subordinated Debt Document or PAIC Subordinated Convertible Note, change
the subordination provisions thereof (including any default or conditions to an
event of default relating thereto), or change any collateral therefor (other
than to release such collateral), if (in the case of this clause (d)), the
effect of such amendment or change, individually or together with all other
amendments or changes made, is to increase the obligations of the obligor
thereunder or to confer any additional rights on the holders of such Senior
Subordinated Debt, the PAIC Subordinated Convertible Note, or any such
Restricted Agreement (or a trustee or other representative on their behalf).

      SECTION 7.2.11. Transactions with Affiliates. The Borrower will not, and
will not permit any of its Restricted Subsidiaries to, enter into, or cause,

            (a) the (i) creation or assumption of any Lien upon its properties,
      revenues or assets, whether now owned or hereafter acquired securing any
      Obligation or any senior refinancing thereof (other than, in the case of
      any assets acquired with the proceeds of any Indebtedness permitted under
      Section 7.2.2(c), customary limitations and prohibitions contained in such
      Indebtedness and in the case of any Indebtedness permitted under clauses

      Borrower (other than customary limitations and prohibitions in any
      Indebtedness permitted under clauses (b), (e), (g), (h) and (i) of Section
      7.2.2 that are applicable to the Restricted Subsidiary of the Borrower
      that has incurred such Indebtedness and its assets; provided, that such
      limitations shall be limited solely to such Restricted Subsidiary (and any
      of its Restricted Subsidiaries) and its (and their) assets).

      SECTION 7.2.13. Securities of Subsidiaries. The Borrower will not permit
any Restricted Subsidiary to issue any Capital Stock (whether for value or
otherwise) to any Person other than the Borrower or another wholly-owned

such Person on the security of such property or rental obligations of the
Borrower or any of its Restricted Subsidiaries.

      SECTION 7.2.15. Designation of Senior Indebtedness. The Borrower will not
permit any Indebtedness (other than the Indebtedness incurred hereunder or under

Obligor shall, directly or indirectly, contest in any manner the effectiveness,
validity, binding nature or enforceability thereof; or any Lien securing any

provide cash collateral to be deposited with the Administrative Agent in an
amount equal to the undrawn amount of all Letters of Credit outstanding and/or

Commitments shall terminate and the Borrower shall deposit with the

                                   ARTICLE IX

                                   THE AGENTS

      SECTION 9.1. Actions. Each Lender hereby appoints CSFB as its Syndication
Agent and UBOC as its Administrative Agent under and for purposes of this
Agreement and each other Loan Document. Each Lender authorizes the Agents to act
on behalf of such Lender under this Agreement and each other Loan Document and,
in the absence of other written instructions from the Required Lenders received
from time to time by the Agents (with respect to which each of the Agents agrees
that it will comply, except as otherwise provided in this Section or as
otherwise advised by counsel), to exercise such powers hereunder and thereunder
as are specifically delegated to or required of the Agents by the terms hereof
and thereof, together with such powers as may be reasonably incidental thereto.
Each Lender hereby indemnifies (which indemnity shall survive any termination of
this Agreement) the Agents, ratably in accordance with their respective Term
Loans outstanding and Commitments (or, if no Term Loans or Commitments are at
the time outstanding and in effect, then ratably in accordance with the
principal amount of Term Loans held by such Lender and their respective
Commitments as in effect in each case on the date of the termination of this
Agreement), from and against any and all liabilities, obligations, losses,
damages, claims, costs or expenses of any kind or nature whatsoever which may at
any time be imposed on, incurred by, or asserted against, either of the Agents
in any way relating to or arising out of this Agreement and any other Loan
Document, including reasonable attorneys' fees, and as to which any Agent is not
reimbursed by the Borrower or any other Obligor (and without limiting the
obligation of the Borrower or any other Obligor to do so); provided, however,
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, claims, costs or expenses which are
determined by a court of competent jurisdiction in a final proceeding to have
resulted solely from such Agent's gross negligence or willful misconduct. The
Agents shall not be required to take any action hereunder or under any other
Loan Document, or

                                      -105-
<PAGE>

to prosecute or defend any suit in respect of this Agreement or any other Loan
Document, unless it is indemnified hereunder to its satisfaction. If any
indemnity in favor of either of the Agents shall be or become, in such Agent's
determination, inadequate, such Agent may call for additional indemnification
from the Lenders and cease to do the acts indemnified against hereunder until
such additional indemnity is given. The Borrower and the Lenders agree that the
Administrative Agent may delegate any of its duties under this Agreement to any
of its Affiliates. Any such Affiliate (and such Affiliate's directors, officers,
agents and employees) which performs duties in connection with this Agreement
shall be entitled to the same benefits of the indemnification, waiver and other
protective provisions to which such Agent is entitled under Articles IX and X.

      SECTION 9.2. Funding Reliance, etc. Unless the Administrative Agent shall
have been notified by telephone, confirmed in writing, by any Lender by 1:00
p.m., Designated City time, on the Business day prior to a Borrowing or
disbursement with respect to a Letter of Credit pursuant to Section 2.6.2 that
such Lender will not make available the amount which would constitute its
Percentage of such Borrowing on the date specified therefor, the Administrative
Agent may assume that such Lender has made such amount available to the
Administrative Agent and, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If and to the extent that such Lender shall
not have made such amount available to the Administrative Agent, such Lender
severally agrees and the Borrower agrees to repay the Administrative Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date the Administrative Agent made such amount available
to the Borrower to the date such amount is repaid to the Administrative Agent,
at the interest rate applicable at the time to Loans comprising such Borrowing.

      SECTION 9.3. Exculpation; Notice of Default. (a) None of the Agents or the
Lead Arranger nor any of their respective directors, officers, employees or
agents shall be liable to any Lender for any action taken or omitted to be taken
by it under this Agreement or any other Loan Document, or in connection herewith
or therewith, except for its own willful misconduct or gross negligence, nor
responsible for any recitals or warranties herein or therein, nor for the
effectiveness, enforceability, validity or due execution of this Agreement or
any other Loan Document, nor for the creation, perfection or priority of any
Liens purported to be created by any of the Loan Documents, or the validity,
genuineness, enforceability, existence, value or sufficiency of any collateral
security, nor to make any inquiry respecting the performance by the Borrower of
its obligations hereunder or under any other Loan Document. Any such inquiry
which may be made by any Agent or any Issuer shall not obligate it to make any
further inquiry or to take any action. The Agents and each Issuer shall be
entitled to rely upon advice of counsel concerning legal matters and upon any
notice, consent, certificate, statement or writing which the Agents or the
Issuers, as applicable, believe to be genuine and to have been presented by a
proper Person.

      (b) No Agent shall be deemed to have knowledge or notice of the occurrence
of any Default or Event of Default hereunder unless such Agent has received
written notice from (A) in the case of the Administrative Agent, a Lender or the
Borrower referring to this Agreement describing such Default or Event of Default
and stating that such notice is a "notice of default"

                                      -106-
<PAGE>

and (B) in the case of the Syndication Agent, from the Administrative Agent as
set forth in the immediately following sentence. In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
prompt notice thereof to the Syndication Agent and the Lenders.

      SECTION 9.4. Successor. The Syndication Agent may resign as such upon one
Business Day's notice to the Borrower and the Administrative Agent. The
Administrative Agent may resign as such at any time upon at least 30 days' prior
notice to the Borrower and all Lenders. If the Administrative Agent at any time
shall resign, the Required Lenders may, with the prior consent of the Borrower
(which consent shall not be unreasonably withheld), appoint another Lender as a
successor Administrative Agent which shall thereupon become the Administrative
Agent hereunder. If no successor Administrative Agent shall have been so
appointed by the Required Lenders, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent's giving notice of
resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which shall be one of the
Lenders or a commercial banking institution organized under the laws of the
United States or a United States branch or agency of a commercial banking
institution, and having a combined capital and surplus of at least $500,000,000.
Upon the acceptance of any appointment as Administrative Agent hereunder by a
successor Administrative Agent, such successor Administrative Agent shall be
entitled to receive from the retiring Administrative Agent such documents of
transfer and assignment as such successor Administrative Agent may reasonably
request, and shall thereupon succeed to and become vested with all rights,
powers, privileges and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and
obligations under this Agreement. After any retiring Administrative Agent's
resignation hereunder as the Administrative Agent, the provisions of (i) this
Article IX shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was the Administrative Agent under this Agreement, and (ii)
Section 10.3 and Section 10.4 shall continue to inure to its benefit.

      SECTION 9.5. Credit Extensions by each Agent. Each Agent and each Issuer
shall have the same rights and powers with respect to (x) (i) in the case of an
Agent, the Credit Extensions made by it or any of its Affiliates and (ii) in the
case of an Issuer, the Loans made by it or any of its Affiliates, and (y) the
Notes held by it or any of its Affiliates as any other Lender and may exercise
the same as if it were not an Agent or Issuer. Each Agent, each Issuer and each
of their respective Affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with the Borrower or any Subsidiary or
Affiliate of the Borrower as if such Agent or Issuer were not an Agent or Issuer
hereunder.

      SECTION 9.6. Credit Decisions. Each Lender acknowledges that it has,
independently of each Agent, the Lead Arranger, each Issuer and each other
Lender, and based on such Lender's review of the financial information of the
Borrower, this Agreement, the other Loan Documents (the terms and provisions of
which being satisfactory to such Lender) and such other documents, information
and investigations as such Lender has deemed appropriate, made its own credit

                                      -107-
<PAGE>

decision to extend its Commitments. Each Lender also acknowledges that it will,
independently of each Agent, the Lead Arranger, each Issuer and each other
Lender, and based on such other documents, information and investigations as it
shall deem appropriate at any time, continue to make its own credit decisions as
to exercising or not exercising from time to time any rights and privileges
available to it under this Agreement or any other Loan Document.

      SECTION 9.7. Copies, etc. The Administrative Agent shall give prompt
notice to each Lender of each notice or request required or permitted to be
given to the Administrative Agent by the Borrower pursuant to the terms of this
Agreement (unless concurrently delivered to the Lenders by the Borrower). The
Administrative Agent will distribute to each Lender each document or instrument
received for such Lender's account and copies of all other communications
received by the Administrative Agent from the Borrower for distribution to the
Lenders by the Administrative Agent in accordance with the terms of this
Agreement.

      SECTION 9.8. The Syndication Agent and the Administrative Agent.
Notwithstanding anything else to the contrary contained in this Agreement or any
other Loan Document, the Agents, in their respective capacities as such, each in
such capacity, shall have no duties or responsibilities under this Agreement or
any other Loan Document nor any fiduciary relationship with any Lender, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or otherwise exist against either
Agent, as applicable, in such capacity except as are explicitly set forth herein
or in the other Loan Documents.

      SECTION 9.9. Documentation Agent. The Lender identified on the signature
pages of this Agreement as the "Documentation Agent" shall not have any right,
power, obligation, liability, responsibility or duty under this Agreement (or
any other Loan Document) other than those applicable to all Lenders as such.
Without limiting the foregoing, the Lender so identified as the "Documentation
Agent" shall not have or be deemed to have any fiduciary relationship with any
other Lender. Each Lender acknowledges that it has not relied, and will not
rely, on the Lender so identified as the "Documentation Agent" in deciding to
enter into this Agreement and each other Loan Document to which it is a party or
in taking or not taking action hereunder or thereunder.

                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

      SECTION 10.1. Waivers, Amendments, etc. The provisions of this Agreement
and of each other Loan Document may from time to time be amended, modified or
waived, if such amendment, modification or waiver is in writing and consented to
by the Borrower and each Obligor party thereto and by the Required Lenders;
provided, however, that any such amendment, modification or waiver of the type
set forth below shall require the consent of the Person or Persons described
below for such amendment, modification or waiver:

                                      -108-
<PAGE>

            (a) Unless consented to by each Lender, no such amendment,
      modification or waiver shall be effective if it would modify any
      requirement hereunder that any particular action be taken by all the
      Lenders, all the Lenders with respect to any Tranche of Loans or
      Commitments or by the Required Lenders, release Holdco from its
      obligations under the Holdco Guaranty and Pledge Agreement, release any
      Subsidiary Guarantor that is a Material Subsidiary from its obligations
      under the Subsidiary Guaranty (except as otherwise provided in the
      Subsidiary Guaranty), if any, or release all or substantially all of the
      collateral security (except in each case as otherwise specifically
      provided in this Agreement, any such Subsidiary Guaranty or a Pledge
      Agreement).

            (b) Unless consented to by each Lender adversely affected thereby,
      no such amendment, modification or waiver shall be effective if it would
      modify this Section 10.1, or clause (i) of Section 10.10, change the
      definition of "Required Lenders", increase any Commitment Amount or the
      Percentage of any Lender (other than pursuant to clause (c) of Section
      2.1.2), reduce any fees described in Section 3.3 (other than the
      administration fee referred to in Section 3.3.2) or extend any Commitment
      Termination Date.

            (c) No such amendment, modification or waiver shall be effective if
      it would extend the Stated Maturity Date for any Loan or reduce the
      principal amount of or rate of interest on or fees payable in respect of
      any Loan or any Reimbursement Obligations (which shall in each case
      include the conversion of all or any part of the Obligations into equity
      of any Obligor), unless such amendment, modification or waiver shall have
      been consented to by the Lender which has made such Loan or, in the case
      of a Reimbursement Obligation, the Issuer owed, and those Lenders
      participating in, such Reimbursement Obligation.

            (d) No such amendment, modification or waiver shall be effective if
      it would affect adversely the interests, rights or obligations of any
      Agent, Issuer or Lead Arranger (in its capacity as Agent, Issuer or Lead
      Arranger), unless such amendment, modification or waiver shall have been
      consented to by such Agent, Issuer or Lead Arranger, as the case may be.

            (e) No such amendment, modification or waiver shall be effective if
      it would have the effect (either immediately or at some later time) of
      enabling the Borrower to satisfy a condition precedent to the making of a
      Revolving Loan or the issuance of a Letter of Credit unless such
      amendment, modification or waiver shall have been consented to by the
      holders of at least 51% of the Revolving Loan Commitments.

            (f) No such amendment, modification or waiver shall be effective if
      it would amend, modify or waive the provisions of clause (a)(i) of Section
      3.1.1 or clause (b) of Section 3.1.2 or effect any amendment, modification
      or waiver that by its terms adversely affects the rights of Lenders
      participating in any Tranche differently from those of Lenders
      participating in other Tranches, unless such amendment, modification or
      waiver shall have

                                      -109-
<PAGE>

      been consented to by the holders of at least 51% of the aggregate amount
      of Loans outstanding under the Tranche or Tranches affected by such
      modification, or, in the case of a modification affecting the Revolving
      Loan Commitments, the Lenders holding at least 51% of the Revolving Loan
      Commitments.

No failure or delay on the part of any Agent, any Issuer, any Lender or any
other Secured Party in exercising any power or right under this Agreement or any
other Loan Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further
exercise thereof or the exercise of any other power or right. No notice to or
demand on the Borrower in any case shall entitle it to any notice or demand in
similar or other circumstances. No waiver or approval by any Agent, any Issuer
or any Lender under this Agreement or any other Loan Document shall, except as
may be otherwise stated in such waiver or approval, be applicable to subsequent
transactions. No waiver or approval hereunder shall require any similar or
dissimilar waiver or approval thereafter to be granted hereunder.

      For purposes of this Section 10.1, the Syndication Agent, in coordination
with the Administrative Agent, shall have primary responsibility, together with
the Borrower, in the negotiation, preparation and documentation relating to any
amendment, modification or waiver under this Agreement, any other Loan Document
or any other agreement or document related hereto or thereto contemplated
pursuant to this Section.

      SECTION 10.2. Notices. All notices and other communications provided to
any party under this Agreement or any other Loan Document shall be in writing or

Administrative Agent shall promptly forward such notice to the address or
facsimile number of such Lender set forth on such Lender's signature page hereto
or on Schedule II hereto or in the Lender Assignment Agreement pursuant to which
such Lender became a Lender hereunder), (b) in the case of any Lender by the

pursuant to which it became a party hereto, (c) in the case of any Agent, at its
address or facsimile number set forth below its signature hereto, and (d) in the
case of the Borrower, to its address or facsimile number set forth on its
signature page hereto, or, in any case, at such address or facsimile number as

indemnifies, exonerates and holds each Agent, each Issuer, the Lead Arranger and
each Lender and each of their respective Affiliates, and each of their
respective partners, officers, directors, employees and agents, and each other
Person controlling any of the foregoing within the meaning of either Section 15
of the Securities Act of 1933, as amended, or Section 20 of the Securities
Exchange Act of 1934, as amended (collectively, the "Indemnified Parties"), free
and harmless from and against any and all actions, causes of action, suits,
losses, costs, liabilities and damages, and expenses actually incurred in
connection therewith (irrespective of whether any such Indemnified Party is a
party to the action for which indemnification hereunder is sought), including
reasonable attorneys' fees and disbursements (collectively, the "Indemnified
Liabilities"), incurred by the Indemnified Parties or any of them as a result
of, or arising out of, or relating to

            (a) any transaction financed or to be financed in whole or in part,
      directly or indirectly, with the proceeds of any Credit Extension;

                                      -111-
<PAGE>

            (b) the entering into and performance of this Agreement and any
      other Loan Document by any of the Indemnified Parties (excluding any
      successful action brought by or on behalf of the Borrower as the result of
      any failure by any Lender to make any Credit Extension hereunder);

            (c) any investigation, litigation or proceeding related to any
      acquisition or proposed acquisition by the Borrower or any of its
      Subsidiaries of all or any portion of the Capital Stock or assets of any
      Person, whether or not such Agent, such Issuer, such Lead Arranger or such
      Lender is party thereto;

            (d) any alleged or actual investigation, litigation or proceeding
      related to any environmental cleanup, audit or noncompliance with or
      liability under any Environmental Law relating to the use, ownership or
      operation by Holdco, the Borrower or any of their respective Subsidiaries
      of any Hazardous Material; or

            (e) the presence on or under, or the escape, seepage, leakage,
      spillage, discharge, emission or release from, any real property owned or
      operated by Holdco, the Borrower or any Subsidiary thereof of any
      Hazardous Material present on or under such property in a manner giving
      rise to liability at or prior to the time Holdco, the Borrower or such
      Subsidiary owned or operated such property (including any losses,
      liabilities, damages, injuries, costs, expenses or claims asserted or
      arising under any Environmental Law), regardless of whether caused by, or
      within the control of, Holdco, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or willful misconduct or any Hazardous Materials that are
manufactured, emitted, generated, treated, released, stored or disposed of on
any real property of the Borrower or any of its Subsidiaries or any violation of
Environmental Law that occurs on or with respect to any real property of the
Borrower or any of its Subsidiaries to the extent occurring after such real
property is transferred to any Indemnified Person or its successor by
foreclosure sale, deed in lieu of foreclosure, or similar transfer, except to
the extent such manufacture, emission, release, generation, treatment, storage
or disposal or violation is actually caused by Holdco, the Borrower or any of
the Borrower's Subsidiaries. The Borrower and its permitted successors and
assigns hereby waive, release and agree not to make any claim, or bring any cost
recovery action against, any Agent, any Issuer, the Lead Arranger or any Lender
under CERCLA or any state equivalent, or any similar law now existing or
hereafter enacted, except to the extent arising out of the gross negligence or
willful misconduct of any Indemnified Party or arising out of any Hazardous
Materials that are manufactured, emitted, generated, treated, released, stored
or disposed of on any real property of the Borrower or any of its Subsidiaries
or any violation of Environmental Law that occurs on or with respect to any real
property of the Borrower or any of its Subsidiaries to the extent occurring
after such real property is transferred to any Indemnified Person or its
successor by foreclosure sale, deed in lieu of foreclosure, or similar transfer.
It is expressly understood and agreed that to the extent that any

                                      -112-
<PAGE>

Indemnified Party is strictly liable under any Environmental Laws, the
Borrower's obligation to such Indemnified Party under this indemnity shall
likewise be without regard to fault on the part of the Borrower, to the extent
permitted under applicable law, with respect to the violation or condition which
results in liability of such Indemnified Party. Notwithstanding anything to the
contrary herein, each Agent, each Issuer, the Lead Arranger and each Lender
shall be responsible with respect to any Hazardous Materials that are
manufactured, emitted, generated, treated, released, stored or disposed of on
any real property of the Borrower or any of its Subsidiaries or any violation of
Environmental Law that occurs on or with respect to any such real property to
the extent it occurs after such real property is transferred to any Agent,
Issuer, Lead Arranger or Lender to its successor by foreclosure sale, deed in
lieu of foreclosure, or similar transfer, except to the extent such manufacture,
emission, release, generation, treatment, storage or disposal or violation is
actually caused by Holdco, the Borrower or any of the Borrower's Subsidiaries.
If and to the extent that the foregoing undertaking may be unenforceable for any
reason, the Borrower hereby agrees to make the maximum contribution to the
payment and satisfaction of each of the Indemnified Liabilities which is
permissible under applicable law.

      SECTION 10.5. Survival. The obligations of the Borrower under Sections
4.3, 4.4, 4.5, 4.6, 10.3 and 10.4, and the obligations of the Lenders under
Sections 4.8 and 9.1, shall in each case survive any termination of this
Agreement, the payment in full of all Obligations and the termination of all
Commitments. The representations and warranties made by the Borrower and each
other Obligor in this Agreement and in each other Loan Document shall survive
the execution and delivery of this Agreement and each such other Loan Document.

      SECTION 10.6. Severability. Any provision of this Agreement or any other
Loan Document which is prohibited or unenforceable in any jurisdiction shall, as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Agreement or such Loan Document or affecting the validity or enforceability
of such provision in any other jurisdiction.

      SECTION 10.7. Headings. The various headings of this Agreement and of each
other Loan Document are inserted for convenience only and shall not affect the
meaning or interpretation of this Agreement or such other Loan Document or any
provisions hereof or thereof.

      SECTION 10.8. Execution in Counterparts. This Agreement may be executed by
the parties hereto in several counterparts, each of which shall be deemed to be
an original and all of which shall constitute together but one and the same
agreement.

      SECTION 10.9. Governing Law; Entire Agreement. THIS AGREEMENT, ANY NOTES
AND, EXCEPT TO THE EXTENT OTHERWISE EXPRESSLY PROVIDED THEREIN, EACH OTHER LOAN
DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY THE

Documents constitute the entire

                                      -113-
<PAGE>

understanding among the parties hereto with respect to the subject matter hereof
and supersede any prior agreements, written or oral, with respect thereto.

      SECTION 10.10. Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that (i) the Borrower may not assign
or transfer its rights or obligations hereunder without the prior written
consent of each of the Agents and all Lenders, and (ii) the rights of sale,
assignment and transfer of the Lenders are subject to Section 10.11.

      SECTION 10.11. Sale and Transfer of Loans and Notes; Participations in

      SECTION 10.11.1. Assignments. Any Lender (the "Assignor Lender"),

            (a) with the written consents of the Borrower, the Agents and (in
      the case of any assignment of participations in Letters of Credit or
      Revolving Loan Commitments) the Issuers (which consents (i) shall not be
      unreasonably delayed or withheld, (ii) of the Borrower shall not be
      required upon the occurrence and during the continuance of any Event of
      Default and (iii) of the Agents and the Issuers shall not be required in
      the case of assignments made by CSFB or any of its Affiliates), may at any
      time assign and delegate to one or more commercial banks, funds that are
      regularly engaged in making, purchasing or investing in loans or
      securities, or other financial institutions, and

            (b) with notice to the Borrower, the Agents, and (in the case of any
      assignment of participations in Letters of Credit or Revolving Loan
      Commitments) the Issuers, but without the consent of the Borrower, the
      Agents or the Issuers, may assign and delegate to any of its Affiliates or
      Related Funds or to any other Lender or any Affiliate or Related Fund of
      any other Lender

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an "Assignee Lender"), all or any fraction of such Assignor Lender's Loans,
participations in Letters of Credit and Letter of Credit Outstandings with
respect thereto and Commitments (which assignment and delegation shall be, as
among Revolving Loan Commitments, Revolving Loans and participations in Letters
of Credit, of a constant, and not a varying, percentage) is in a minimum
aggregate amount of (i) $2,000,000 (provided that (1) assignments that are made
on the same day to funds that (x) invest in commercial loans and (y) are managed
or advised by the same investment advisor or any Affiliate of such investment
advisor may be treated as a single assignment for purposes of the minimum amount
and (2) no minimum amount shall be required in the case of any assignment
between two Lenders so long as the Assignor Lender has an aggregate amount of
Loans and Commitments of at least $2,000,000 following such assignment) unless
the Borrower and the

                                      -114-
<PAGE>

Agents otherwise consent or (ii) the then remaining amount of such Assignor
Lender's Loans and Commitments; provided, however, that any such Assignee Lender
will comply, if applicable, with the provisions contained in Section 4.6 and the
Borrower, each other Obligor and the Agents shall be entitled to continue to
deal solely and directly with such Assignor Lender in connection with the
interests so assigned and delegated to an Assignee Lender until

            (c) written notice of such assignment and delegation, together with
      payment instructions, addresses and related information with respect to
      such Assignee Lender, shall have been given to the Borrower and the Agents
      by such Assignor Lender and such Assignee Lender;

            (d) such Assignee Lender shall have executed and delivered to the
      Borrower and the Agents a Lender Assignment Agreement, accepted by the
      Agents;

            (e) the processing fees described below shall have been paid; and

            (f) the Administrative Agent shall have registered such assignment
      and delegation in the Register pursuant to clause (b) of Section 2.7.

From and after the date that the Agents accept such Lender Assignment Agreement
and such assignment and delegation is registered pursuant to clause (b) of
Section 2.7, (x) the Assignee Lender thereunder shall be deemed automatically to
have become a party hereto and to the extent that rights and obligations
hereunder have been assigned and delegated to such Assignee Lender in connection
with such Lender Assignment Agreement, shall have the rights and obligations of
a Lender hereunder and under the other Loan Documents, and (y) the Assignor
Lender, to the extent that rights and obligations hereunder have been assigned
and delegated by it in connection with such Lender Assignment Agreement, shall
be released from its obligations hereunder and under the other Loan Documents.
Any Assignor Lender that shall have previously requested and received any Note
or Notes in respect of any Tranche to which any such assignment applies shall,
upon the acceptance by the Administrative Agent of the applicable Lender
Assignment Agreement, mark such Note or Notes "exchanged" and deliver them to
the Borrower (against, if the Assignor Lender has retained Loans or Commitments
with respect to the applicable Tranche and has requested replacement Notes
pursuant to clause (b)(ii) of Section 2.7, its receipt from the Borrower of
replacement Notes in the principal amount of the Loans and Commitments of the
applicable Tranche retained by it). Such Assignor Lender or such Assignee Lender
(unless the Assignor Lender or the Assignee Lender is CSFB or one of its
Affiliates) must also pay a processing fee to the Administrative Agent upon
delivery of any Lender Assignment Agreement in the amount of $2,500 (with only
one such fee payable in connection with simultaneous assignments from the same
Assignor Lender to Assignee Lenders that are Related Funds), unless such
assignment and delegation is by a Lender to its Affiliate or Related Fund or if
such assignment and delegation is by a Lender to a Federal Reserve Bank, as
provided below or is otherwise consented to by the Administrative Agent. Any
attempted assignment and delegation not made in accordance with this Section
10.11.1 shall be null and void. Nothing contained in this

                                      -115-

Section 10.11.1 shall prevent or prohibit any Lender from pledging its rights
(but not its obligations to make Loans or participate in Letters of Credit of
Letter of Credit Outstandings) under this Agreement and/or its Loans hereunder
to a Federal Reserve Bank in support of borrowings made by such Lender from such
Federal Reserve Bank and any Lender that is a fund that invests in bank loans
may pledge all or any portion of its rights (but not its obligations to make
Loans or participate in Letters of Credit or Letter of Credit Outstandings)
hereunder to any trustee or any other representative of holders of obligations
owed or securities issued by such fund as security for such obligations or
securities. In the event that S&P, Moody's or Thompson's BankWatch (or
InsuranceWatch Ratings Service, in the case of Lenders that are insurance
companies (or Best's Insurance Reports, if such insurance company is not rated
by Insurance Watch Ratings Service)) shall, after the date that any Lender with
a Commitment to make Revolving Loans or participate in Letters of Credit becomes
a Lender, downgrade the long- term certificate of deposit rating or long-term
senior unsecured debt rating of such Lender, and the resulting rating shall be
below BBB-, Baa3 or C (or BB, in the case of Lender that is an insurance company
(or B, in the case of an insurance company not rated by InsuranceWatch Ratings
Service)) respectively, then the applicable Issuer or the Borrower shall have
the right, but not the obligation, upon notice to such Lender and the Agents, to
replace such Lender with an Assignee Lender in accordance with and subject to
the restrictions contained in this Section, and such Lender hereby agrees to
transfer and assign without recourse (in accordance with and subject to the
restrictions contained in this Section) all its interests, rights and
obligations in respect of its Revolving Loan Commitment under this Agreement to
such Assignee Lender; provided, however, that (i) no such assignment shall
conflict with any law, regulation or order of any governmental authority and
(ii) such Assignee Lender shall pay to such Lender in immediately available
funds on the date of such assignment the principal of and interest and fees (if
any) accrued to the date of payment on the Loans made, and Letters of Credit
participated in, by such Lender hereunder and all other amounts accrued for such
Lender's account or owed to it hereunder.

      SECTION 10.11.2. Participations. Any Lender may at any time sell to one or
more commercial banks or other Persons (each such commercial bank and other
Person being herein called a "Participant") participating interests in any of
the Loans, Commitments, participations in Letters of Credit and Letters of
Credit Outstandings or other interests of such Lender hereunder; provided,
however, that

            (a) no participation contemplated in this Section shall relieve such
      Lender from its Commitments or its other obligations hereunder or under
      any other Loan Document;

            (b) such Lender shall remain solely responsible for the performance
      of its Commitments and such other obligations;

            (c) the Borrower and each other Obligor and the Agents shall
      continue to deal solely and directly with such Lender in connection with
      such Lender's rights and obligations under this Agreement and each of the
      other Loan Documents;

                                      -116-
<PAGE>

            (d) no Participant, unless such Participant is an Affiliate of such
      Lender, or is itself a Lender, shall be entitled to require such Lender to
      take or refrain from taking any action hereunder or under any other Loan
      Document, except that such Lender may agree with any Participant that such
      Lender will not, without such Participant's consent, agree to (i) any
      reduction in the interest rate or amount of fees that such Participant is
      otherwise entitled to, (ii) a decrease in the principal amount, or an
      extension of the final Stated Maturity Date, of any Loan in which such
      Participant has purchased a participating interest or (iii) a release of
      all or substantially all of the collateral security under the Loan
      Documents or any Material Subsidiary that is a Subsidiary Guarantor under
      the Subsidiary Guaranty, in each case except as otherwise specifically
      provided in a Loan Document; and

            (e) the Borrower shall not be required to pay any amount under
      Sections 4.3, 4.4, 4.5, 4.6, 10.3 and 10.4 that is greater than the amount
      which it would have been required to pay had no participating interest
      been sold.

The Borrower acknowledges and agrees, subject to clause (e) above, that, to the
fullest extent permitted under applicable law, each Participant, for purposes of
Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 10.3 and 10.4, shall be considered a
Lender.

      SECTION 10.12. Other Transactions. Nothing contained herein shall preclude
any Agent or any other Lender from engaging in any transaction, in addition to
those contemplated by this Agreement or any other Loan Document, with the
Borrower or any of its Affiliates in which the Borrower or such Affiliate is not
restricted hereby from engaging with any other Person.

      SECTION 10.13. Forum Selection and Consent to Jurisdiction. ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE LENDERS, THE ISSUERS
OR THE BORROWER RELATING THERETO SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY (TO
THE EXTENT PERMITTED UNDER APPLICABLE LAW) IN THE COURTS OF THE STATE OF NEW
YORK, NEW YORK COUNTY, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN

AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE
AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER
PROPERTY MAY BE FOUND. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK, NEW YORK COUNTY, AND OF
THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE
PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE
BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH

                                      -117-
<PAGE>

SUCH LITIGATION. THE BORROWER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY
REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE
STATE OF NEW YORK. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER
MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT
REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM. TO THE EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY ACQUIRE
ANY IMMUNITY FROM JURISDICTION OF ANY COURT OF FROM ANY LEGAL PROCESS (WHETHER
THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF
EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWER
HEREBY IRREVOCABLY WAIVES (TO THE EXTENT PERMITTED UNDER APPLICABLE LAW) SUCH
IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS.

      SECTION 10.14. Waiver of Jury Trial. THE AGENTS, THE ISSUERS, THE LENDERS
AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE ISSUERS, THE LENDERS OR
THE BORROWER RELATING THERETO. THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS
RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER
PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENTS AND THE LENDERS ENTERING INTO
THIS AGREEMENT AND EACH SUCH OTHER LOAN DOCUMENT.

      SECTION 10.15. Confidentiality. The Agents, the Issuers, the Lead Arranger
and the Lenders shall hold all non-public information obtained pursuant to or in
connection with this Agreement or obtained by them based on a review of the
books and records of the Borrower or any of its Subsidiaries in accordance with
their customary procedures for handling confidential information of this nature,
but may make disclosure to any of their examiners, Affiliates, Related Funds,
investment advisors or Affiliates thereof, outside auditors, counsel and other

      each Agent, each Issuer, the Lead Arranger and each Lender shall promptly
      notify the Borrower of any request by any governmental agency or
      representative thereof (other than any such request in connection with an
      examination of the financial condition of such Agent, such Issuer, the
      Lead Arranger and such Lender by such governmental agency) for disclosure
      of any such non-public information prior to disclosure of such
