                                       15



     "Withdrawal Liability" means liability to a Multiemployer Plan as a result
of a complete or partial withdrawal from such Multiemployer Plan, as such terms
are defined in Part I of Subtitle E of Title IV of ERISA.

     SECTION 1.2. Classification of Loans and Borrowings. For purposes of this
Agreement, Loans may be classified and referred to by Class (e.g., a "Revolving
Loan") or by Type (e.g., a "Eurodollar Loan") or by Class and Type (e.g., a
"Eurodollar Revolving Loan"). Borrowings also may be classified and referred to
by Class (e.g., a "Revolving Borrowing") or by Type (e.g., a "Eurodollar
Borrowing") or by Class and Type (e.g., a "Eurodollar Revolving Borrowing").

     SECTION 1.3. Terms Generally. The definitions of terms herein shall apply
equally to the singular and plural forms of the terms defined. Whenever the
context may require, any pronoun shall include the corresponding masculine,
feminine and neuter forms. The words "include", "includes" and "including" shall
be deemed to be followed by the phrase "without limitation". The word "will"
shall be construed to have the same meaning and effect as the word "shall".
Unless the context requires otherwise (a) any definition of or reference to any
agreement, instrument or other document herein shall be construed as referring
to such agreement, instrument or other document as from time to time amended,
supplemented or otherwise modified (subject to any restrictions on such
amendments, supplements or modifications set forth herein), (b) any reference
herein to any Person shall be construed to include such Person's successors and
assigns, (c) the words "herein", "hereof" and "hereunder", and words of similar

     SECTION 1.4. Accounting Terms; GAAP. If at any time any change in GAAP
would affect the computation of any financial ratio or requirement set forth in
any Loan Document, and either the Borrower or the Required Lenders shall so
request, the Administrative Agent, the Lenders and the Borrower shall negotiate
in good faith to amend such ratio or requirement to preserve the original intent
thereof in light of such change in GAAP (subject to the approval of the Required
Lenders); provided, that until so amended, (i) such ratio or requirement shall
continue to be computed in accordance with GAAP prior to such change therein and
(ii) the Borrower shall provide to the Administrative Agent and the Lenders
financial statements and other documents required under this Agreement or as
reasonably requested hereunder setting forth a reconciliation between
calculations of such ratio or requirement made before and after giving effect to
such change in GAAP. Borrower has advised the Administrative Agent that it does,
and is required to, consolidate CCT in its consolidated financial statements,
but that Borrower does not have the power to control CCT. Accordingly, financial
position, results of operations and cash flows of CCT shall be included for the
purpose of (a) the definitions of "Consolidated EBTIDA", "Consolidated Interest
Charges", "Consolidated Net Worth" and "Consolidated Total Debt", (b) the
financial statements and reporting requirements in Section 5.1 and (c)
determining compliance with the financial covenants in Section 6.9. CCT shall

the closing conditions in Article IV, the affirmative covenants in Article V,
the negative covenants in Article VI, and the events of default in Article VII.

                                   ARTICLE II.
                                   THE CREDITS

     SECTION 2.1. Commitments. Subject to the terms and conditions set forth
herein, each Lender agrees to make Revolving Loans to the Borrower from time to
time during the Availability Period in an aggregate principal amount that will
not result in such Lender's Revolving Credit Exposure exceeding such Lender's
Commitment. Within the foregoing limits and subject to the terms and conditions
set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans.

     SECTION 2.2. Loans and Borrowings. (a) Each Revolving Loan shall be made as
part of a Borrowing consisting of Revolving Loans made by the Lenders ratably in
accordance with their respective Commitments. The failure of any Lender to make
any Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments of the Lenders are several
and no Lender shall be responsible for any other Lender's failure to make Loans
as required.

          (b) Subject to Section 2.13, each Revolving Borrowing shall be
     comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may
     request in accordance herewith. Each Swingline Loan shall be an ABR Loan.
     Each Lender at its option may make any Eurodollar Loan by causing any
     domestic or foreign branch or Affiliate of such Lender to make such Loan
     (so long as such election of a foreign branch or Affiliate does not
     increase the Borrower's cost hereunder); provided that any exercise of such
     option shall not affect the obligation of the Borrower to repay such Loan
     in accordance with the terms of this Agreement.

          (c) At the commencement of each Interest Period for any Eurodollar
     Revolving Borrowing, such Borrowing shall be in an aggregate amount that is
     an integral multiple of $500,000 and not less than $3,000,000. At the time
     that each ABR Revolving Borrowing is made, such Borrowing shall be in an
     aggregate amount that is an integral multiple of $250,000 and not less than
     $1,000,000; provided that an ABR Revolving Borrowing may be in an aggregate
     amount that is equal to the entire unused balance of the total Commitments
     or that is required to finance the reimbursement of an LC Disbursement as
     contemplated by Section 2.5(e). Each Swingline Loan shall be in an amount
     that is an integral multiple of $100,000 and not less than $1,000,000.
     Borrowings of more than one Type and Class may be outstanding at the same
     time; provided that there shall not at any time be more than a total of 12
     Eurodollar Revolving Borrowings outstanding.

          (d) Notwithstanding any other provision of this Agreement, the
     Borrower shall not be entitled to request, or to elect to convert or
     continue, any Borrowing if the Interest Period requested with respect
     thereto would end after the Maturity Date.


                                       17



     SECTION 2.3. Requests for Revolving Borrowings. To request a Revolving
Borrowing, the Borrower shall notify the Administrative Agent of such request by
telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m.,
New York City time, three Business Days before the date of the proposed
Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New
York City time, on the same day of the proposed Borrowing; provided that any
such notice of an ABR Revolving Borrowing to finance the reimbursement of an LC
Disbursement as contemplated by Section 2.5(e) may be given not later than 10:00
a.m., New York City time, on the date of the proposed Borrowing. Each such
telephonic Borrowing Request shall be irrevocable and shall be confirmed
promptly by hand delivery or telecopy to the Administrative Agent of a written
Borrowing Request in a form approved by the Administrative Agent and signed by
the Borrower. Each such telephonic and written Borrowing Request shall specify
the following information in compliance with Section 2.2:

               (i) the aggregate amount of the requested Borrowing;

               (ii) the date of such Borrowing, which shall be a Business Day;

               (iii) whether such Borrowing is to be an ABR Borrowing or a
          Eurodollar Borrowing;

               (iv) in the case of a Eurodollar Borrowing, the initial Interest
          Period to be applicable thereto, which shall be a period contemplated
          by the definition of the term "Interest Period"; and

               (v) the location and number of the Borrower's account to which
          funds are to be disbursed, which shall comply with the requirements of
          Section 2.6.

If no election as to the Type of Revolving Borrowing is specified, then the
requested Revolving Borrowing shall be an ABR Borrowing. If no Interest Period
is specified with respect to any requested Eurodollar Revolving Borrowing, then
the Borrower shall be deemed to have selected an Interest Period of one month's
duration. Promptly following receipt of a Borrowing Request in accordance with
this Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Loan to be made as part of the
requested Borrowing.

     SECTION 2.4. Swingline Loans. (a) Subject to the terms and conditions set
forth herein, the Swingline Lender agrees to make Swingline Loans to the
Borrower from time to time during the Availability Period, in an aggregate
principal amount at any time outstanding that will not result in (i) the
aggregate principal amount of outstanding Swingline Loans exceeding $20,000,000
or (ii) the aggregate Revolving Credit Exposures of all Lenders exceeding the
total Commitments; provided that the Swingline Lender shall not be required to
make a Swingline Loan to refinance an outstanding Swingline Loan. Within the
foregoing limits and subject to the terms and conditions set forth herein, the
Borrower may borrow, prepay and reborrow Swingline Loans.

          (b) To request a Swingline Loan, the Borrower shall notify the
     Administrative Agent of such request by telephone (confirmed by telecopy),
     not later than 1:00 p.m., New York City time, on the day of a proposed
     Swingline Loan. Each such notice shall be irrevocable and shall specify the
     requested date (which shall be a Business Day) and


                                       18



     amount of the requested Swingline Loan and other relevant information that
     would be required under Section 2.3 if the Swingline Loan were a Revolving
     Borrowing. The Administrative Agent will promptly advise the Swingline
     Lender of any such notice received from the Borrower. The Swingline Lender
     shall make each Swingline Loan available to the Borrower by means of a
     credit to the general deposit account of the Borrower with the Swingline
     Lender (or, in the case of a Swingline Loan made to finance the
     reimbursement of an LC Disbursement as provided in Section 2.5(e), by
     remittance to the Issuing Bank) by 3:00 p.m., New York City time, on the
     requested date of such Swingline Loan.

          (c) The Swingline Lender may by written notice given to the
     Administrative Agent not later than 1:00 p.m., New York City time, on any
     Business Day require the applicable Lenders to acquire participations on
     such Business Day in all or a portion of the Swingline Loans outstanding.
     Such notice shall specify the aggregate amount of Swingline Loans in which
     the applicable Lenders will participate. Promptly upon receipt of such
     notice, the Administrative Agent will give notice thereof to each
     applicable Lender, specifying in such notice such Lender's Applicable
     Percentage of such Swingline Loan or Loans. Each applicable Lender hereby
     absolutely and unconditionally agrees, upon receipt of notice as provided
     above, to promptly pay to the Administrative Agent, for the account of the
     Swingline Lender, such Lender's Applicable Percentage of such Swingline
     Loan or Loans. Each applicable Lender acknowledges and agrees that its
     obligation to acquire participations in Swingline Loans pursuant to this
     paragraph is absolute and unconditional and shall not be affected by any
     circumstance whatsoever, including the occurrence and continuance of a
     Default or reduction or termination of the Commitments, and that each such
     payment shall be made without any offset, abatement, withholding or
     reduction whatsoever. Each applicable Lender shall comply with its
     obligation under this paragraph by wire transfer of immediately available
     funds, in the same manner as provided in Section 2.6 with respect to Loans
     made by such Lender (and Section 2.6 shall apply, mutatis mutandis, to the
     payment obligations of the Lenders), and the Administrative Agent shall
     promptly pay to the Swingline Lender the amounts so received by it from the
     Lenders. The Administrative Agent shall notify the Borrower of any
     participations in any Swingline Loan acquired pursuant to this paragraph,
     and thereafter payments in respect of such Swingline Loan shall be made to
     the Administrative Agent and not to the Swingline Lender. Any amounts
     received by the Swingline Lender from the Borrower (or other party on
     behalf of the Borrower) in respect of a Swingline Loan after receipt by the
     Swingline Lender of the proceeds of a sale of participations therein shall
     be promptly remitted to the Administrative Agent; any such amounts received
     by the Administrative Agent shall be promptly remitted by the
     Administrative Agent to the Lenders that shall have made their payments
     pursuant to this paragraph and to the Swingline Lender, as their interests
     may appear; provided that any such payment so remitted shall be repaid to
     the Swingline Lender or to the Administrative Agent, as applicable, if and
     to the extent such payment is required to be refunded to the Borrower for
     any reason. The purchase of participations in a Swingline Loan pursuant to
     this paragraph shall not relieve the Borrower of any default in the payment
     thereof.


                                       19


     SECTION 2.5. Letters of Credit. (a) General. Subject to the terms and
conditions set forth herein, the Borrower may request the issuance of Letters of
Credit for its own account, in a form reasonably acceptable to the
Administrative Agent and the Issuing Bank, at any time and from time to time
during the Availability Period. In the event of any inconsistency between the
terms and conditions of this Agreement and the terms and conditions of any form
of letter of credit application or other agreement submitted by the Borrower to,
or entered into by the Borrower with, the Issuing Bank relating to any Letter of
Credit, the terms and conditions of this Agreement shall control.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
     Conditions. To request the issuance of a Letter of Credit (or the
     amendment, renewal or extension of an outstanding Letter of Credit), the
     Borrower shall hand deliver or telecopy (or transmit by electronic
     communication, if arrangements for doing so have been approved by the
     Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably
     in advance of the requested date of issuance, amendment, renewal or
     extension) a notice requesting the issuance of a Letter of Credit, or
     identifying the Letter of Credit to be amended, renewed or extended, and
     specifying the date of issuance, amendment, renewal or extension (which
     shall be a Business Day), the date on which such Letter of Credit is to
     expire (which shall comply with paragraph (c) of this Section), the amount
     of such Letter of Credit, the name and address of the beneficiary thereof
     and such other information as shall be necessary to prepare, amend, renew
     or extend such Letter of Credit. If requested by the Issuing Bank, the
     Borrower also shall submit a letter of credit application on the Issuing
     Bank's standard form in connection with any request for a Letter of Credit.
     A Letter of Credit shall be issued, amended, renewed or extended only if
     (and upon issuance, amendment, renewal or extension of each Letter of
     Credit the Borrower shall be deemed to represent and warrant that), after
     giving effect to such issuance, amendment, renewal or extension (i) the LC
     Exposure shall not exceed $10,000,000 and (ii) the aggregate Revolving
     Credit Exposures of all Lenders shall not exceed the total Commitments.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to
     the close of business on the earlier of (i) the date one year after the
     date of the issuance of such Letter of Credit (or, in the case of any
     renewal or extension thereof, one year after such renewal or extension) and
     (ii) the date that is five Business Days prior to the Maturity Date;
     provided that any Letter of Credit with a one-year term may provide for the
     renewal thereof for additional one-year periods (which in no event shall
     extend beyond the date referred to in clause (ii) above).

          (d) Participations. By the issuance of a Letter of Credit (or an
     amendment to a Letter of Credit increasing the amount thereof) and without
     any further action on the part of the Issuing Bank or the Lenders, the
     Issuing Bank hereby grants to each Lender, and each Lender hereby acquires
     from the Issuing Bank, a participation in such Letter of Credit equal to
     such Lender's Applicable Percentage of the aggregate amount available to be
     drawn under such Letter of Credit. In consideration and in furtherance of
     the foregoing, each Lender hereby absolutely and unconditionally agrees to
     pay to the Administrative Agent, for the account of the Issuing Bank, such
     Lender's Applicable Percentage of each LC Disbursement made by the Issuing
     Bank and not reimbursed by


                                       20



     the Borrower on the date due as provided in paragraph (e) of this Section,
     or of any reimbursement payment required to be refunded to the Borrower for
     any reason. Each Lender acknowledges and agrees that its obligation to
     acquire participations pursuant to this paragraph in respect of Letters of
     Credit is absolute and unconditional and shall not be affected by any
     circumstance whatsoever, including any amendment, renewal or extension of
     any Letter of Credit or the occurrence and continuance of a Default or
     reduction or termination of the Commitments, and that each such payment
     shall be made without any offset, abatement, withholding or reduction
     whatsoever.

          (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement
     in respect of a Letter of Credit, the Borrower shall reimburse such LC
     Disbursement by paying to the Administrative Agent an amount equal to such
     LC Disbursement not later than 12:00 noon, New York City time, on the date
     that such LC Disbursement is made, if the Borrower shall have received
     notice of such LC Disbursement prior to 10:00 a.m., New York City time, on
     such date, or, if such notice has not been received by the Borrower prior
     to such time on such date, then not later than 12:00 noon, New York City
     time, on the Business Day immediately following the day that the Borrower
     receives such notice; provided that if such LC Disbursement is not less
     than $100,000, the Borrower may, subject to the conditions to borrowing set
     forth herein, request in accordance with Section 2.3 or 2.4 that such
     payment be financed with an ABR Revolving Borrowing or Swingline Loan in an
     equivalent amount and, to the extent so financed, the Borrower's obligation
     to make such payment shall be discharged and replaced by the resulting ABR
     Revolving Borrowing or Swingline Loan. If the Borrower fails to make such
     payment when due, the Administrative Agent shall notify each Lender of the
     applicable LC Disbursement, the payment then due from the Borrower in
     respect thereof and such Lender's Applicable Percentage thereof. Promptly
     following receipt of such notice, each Lender shall pay to the
     Administrative Agent its Applicable Percentage of the payment then due from
     the Borrower, in the same manner as provided in Section 2.6 with respect to
     Loans made by such Lender (and Section 2.7 shall apply, mutatis mutandis,
     to the payment obligations of the Lenders), and the Administrative Agent
     shall promptly pay to the Issuing Bank the amounts so received by it from
     the Lenders. Promptly following receipt by the Administrative Agent of any
     payment from the Borrower pursuant to this paragraph, the Administrative
     Agent shall distribute such payment to the Issuing Bank or, to the extent
     that Lenders have made payments pursuant to this paragraph to reimburse the
     Issuing Bank, then to such Lenders and the Issuing Bank as their interests
     may appear. Any payment made by a Lender pursuant to this paragraph to
     reimburse the Issuing Bank for any LC Disbursement (other than the funding
     of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not
     constitute a Loan and shall not relieve the Borrower of its obligation to
     reimburse such LC Disbursement.

          (f) Obligations Absolute. Subject to the provisions of the next
     sentence, the Borrower's obligation to reimburse LC Disbursements as
     provided in paragraph (e) of this Section shall be absolute, unconditional
     and irrevocable, and shall be performed strictly in accordance with the
     terms of this Agreement under any and all circumstances whatsoever and
     irrespective of (i) any lack of validity or enforceability of any Letter of
     Credit or this Agreement, or any term or provision therein, (ii) any draft
     or other document presented under a Letter of Credit proving to be forged,
     fraudulent or invalid in


                                       21



     any respect or any statement therein being untrue or inaccurate in any
     respect, (iii) payment by the Issuing Bank under a Letter of Credit against
     presentation of a draft or other document that does not strictly comply
     with the terms of such Letter of Credit, or (iv) any other event or
     circumstance whatsoever, whether or not similar to any of the foregoing,
     that might, but for the provisions of this Section, constitute a legal or
     equitable discharge of, or provide a right of setoff against, the
     Borrower's obligations hereunder. Neither the Administrative Agent, the
     Lenders nor the Issuing Bank, nor any of their Related Parties, shall have
     any liability or responsibility by reason of or in connection with the
     issuance or transfer of any Letter of Credit or any payment or failure to
     make any payment thereunder (irrespective of any of the circumstances
     referred to in the preceding sentence), or any error, omission,
     interruption, loss or delay in transmission or delivery of any draft,
     notice or other communication under or relating to any Letter of Credit
     (including any document required to make a drawing thereunder), any error
     in interpretation of technical terms or any consequence arising from causes
     beyond the control of the Issuing Bank; provided that the foregoing shall
     not be construed to excuse the Issuing Bank from liability to the Borrower
     to the extent of any direct damages (as opposed to consequential damages,
     claims in respect of which are hereby waived by the Borrower to the extent
     permitted by applicable law) suffered by the Borrower that are caused by
     the Issuing Bank's failure to exercise care when determining whether drafts
     and other documents presented under a Letter of Credit comply with the
     terms thereof. The parties hereto expressly agree that, in the absence of
     gross negligence or willful misconduct on the part of the Issuing Bank (as
     finally determined by a court of competent jurisdiction), the Issuing Bank
     shall be deemed to have exercised care in each such determination. In
     furtherance of the foregoing and without limiting the generality thereof,
     the parties agree that, with respect to documents presented which appear on
     their face to be in substantial compliance with the terms of a Letter of
     Credit, the Issuing Bank may, in its sole discretion, either accept and
     make payment upon such documents without responsibility for further
     investigation, regardless of any notice or information to the contrary, or
     refuse to accept and make payment upon such documents if such documents are
     not in strict compliance with the terms of such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly
     following its receipt thereof, examine all documents purporting to
     represent a demand for payment under a Letter of Credit. The Issuing Bank
     shall promptly notify the Administrative Agent and the Borrower by
     telephone (confirmed by telecopy) of such demand for payment and whether
     the Issuing Bank has made or will make an LC Disbursement thereunder;
     provided that any failure to give or delay in giving such notice shall not
     relieve the Borrower of its obligation to reimburse the Issuing Bank and
     the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If the Issuing Bank shall make any LC
     Disbursement, then, unless the Borrower shall reimburse such LC
     Disbursement in full on the date such LC Disbursement is made, the unpaid
     amount thereof shall bear interest, for each day from and including the
     date such LC Disbursement is made to but excluding the date that the
     Borrower reimburses such LC Disbursement, at the rate per annum then
     applicable to ABR Revolving Loans; provided that if the Borrower fails to
     reimburse such LC Disbursement when due pursuant to paragraph (e) of this
     Section, then Section 2.12(d)


                                       22



     shall apply. Interest accrued pursuant to this paragraph shall be for the
     account of the Issuing Bank, except that interest accrued on and after the
     date of payment by any Lender pursuant to paragraph (e) of this Section to
     reimburse the Issuing Bank shall be for the account of such Lender to the
     extent of such payment.

          (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced
     at any time by written agreement among the Borrower, the Administrative
     Agent, the replaced Issuing Bank and the successor Issuing Bank. The
     Administrative Agent shall notify the Lenders of any such replacement of
     the Issuing Bank. At the time any such replacement shall become effective,
     the Borrower shall pay all unpaid fees accrued for the account of the
     replaced Issuing Bank pursuant to Section 2.11(b). From and after the
     effective date of any such replacement, (i) the successor Issuing Bank
     shall have all the rights and obligations of the Issuing Bank under this
     Agreement with respect to Letters of Credit to be issued thereafter and
     (ii) references herein to the term "Issuing Bank" shall be deemed to refer
     to such successor or to any previous Issuing Bank, or to such successor and
     all previous Issuing Banks, as the context shall require. After the
     replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall
     remain a party hereto and shall continue to have all the rights and
     obligations of an Issuing Bank under this Agreement with respect to Letters
     of Credit issued by it prior to such replacement, but shall not be required
     to issue additional Letters of Credit.

          (j) Cash Collateralization. If any Event of Default shall occur and be
     continuing, on the Business Day that the Borrower receives notice from the
     Administrative Agent or the Required Lenders (or, if the maturity of the
     Loans has been accelerated, Lenders with LC Exposure representing greater
     than 66 and 2/3% of the total LC Exposure) demanding the deposit of cash
     collateral pursuant to this paragraph, the Borrower shall deposit in an
     account with the Administrative Agent, in the name of the Administrative
     Agent and for the benefit of the Lenders, an amount in cash equal to the LC
     Exposure as of such date plus any accrued and unpaid interest thereon;
     provided that the obligation to deposit such cash collateral shall become
     effective immediately, and such deposit shall become immediately due and
     payable, without demand or other notice of any kind, upon the occurrence of
     any Event of Default with respect to the Borrower described in clause (h)
     or (i) of Article VII. Such deposit shall be held by the Administrative
     Agent as collateral for the payment and performance of the obligations of
     the Borrower under this Agreement. The Administrative Agent shall have
     exclusive dominion and control, including the exclusive right of
     withdrawal, over such account. Other than any interest earned on the
     investment of such deposits, which investments shall be made at the option
     and sole discretion of the Administrative Agent and at the Borrower's risk
     and expense, such deposits shall not bear interest. Interest or profits, if
     any, on such investments shall accumulate in such account. Moneys in such
     account shall be applied by the Administrative Agent to reimburse the
     Issuing Bank for LC Disbursements for which it has not been reimbursed and,
     to the extent not so applied, shall be held for the satisfaction of the
     reimbursement obligations of the Borrower for the LC Exposure at such time
     or, if the maturity of the Loans has been accelerated (but subject to the
     consent of Lenders with LC Exposure representing greater than 66 and 2/3%
     of the total LC Exposure), be applied to satisfy other obligations of the
     Borrower under this Agreement. If the Borrower is required to provide an
     amount of cash collateral


                                       23



     hereunder as a result of the occurrence of an Event of Default, such amount
     (to the extent not applied as aforesaid) shall be returned to the Borrower
     within three Business Days after all Events of Default have been cured or
     waived.

     SECTION 2.6. Funding of Borrowings. (a) Each Lender shall make each Loan to
be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds by 12:00 noon, New York City time, to the account of
the Administrative Agent most recently designated by it for such purpose by
notice to the Lenders; provided that Swingline Loans shall be made as provided
in Section 2.4. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to an
account of the Borrower designated by the Borrower in the applicable Borrowing
Request; provided that ABR Revolving Loans made to finance the reimbursement of
an LC Disbursement as provided in Section 2.5(e) shall be remitted by the
Administrative Agent to the Issuing Bank.

          (b) Unless the Administrative Agent shall have received notice from a
     Lender prior to the proposed date of any Borrowing that such Lender will
     not make available to the Administrative Agent such Lender's share of such
     Borrowing, the Administrative Agent may assume that such Lender has made
     such share available on such date in accordance with paragraph (a) of this
     Section and may, in reliance upon such assumption, make available to the
     Borrower a corresponding amount. In such event, if a Lender has not in fact
     made its share of the applicable Borrowing available to the Administrative
     Agent, then the applicable Lender and the Borrower severally agree to pay
     to the Administrative Agent forthwith on demand such corresponding amount
     with interest thereon, for each day from and including the date such amount
     is made available to the Borrower to but excluding the date of payment to
     the Administrative Agent, at (i) in the case of such Lender, the greater of
     the Federal Funds Effective Rate and a rate determined by the
     Administrative Agent in accordance with banking industry rules on interbank
     compensation or (ii) in the case of the Borrower, the interest rate
     applicable to ABR Loans. If such Lender pays such amount to the
     Administrative Agent, then such amount shall constitute such Lender's Loan
     included in such Borrowing.

     SECTION 2.7. Interest Elections. (a) Each Revolving Borrowing initially
shall be of the Type specified in the applicable Borrowing Request and, in the
case of a Eurodollar Revolving Borrowing, shall have an initial Interest Period
as specified in such Borrowing Request. Thereafter, the Borrower may elect to
convert such Borrowing to a different Type or to continue such Borrowing and, in
the case of a Eurodollar Revolving Borrowing, may elect Interest Periods
therefor, all as provided in this Section. The Borrower may elect different
options with respect to different portions of the affected Borrowing, in which
case each such portion shall be allocated ratably among the Lenders holding the
Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing. This Section shall not apply to
Swingline Borrowings, which may not be converted or continued.

          (b) To make an election pursuant to this Section, the Borrower shall
     notify the Administrative Agent of such election by telephone by the time
     that a Borrowing Request would be required under Section 2.3 if the
     Borrower were requesting a Revolving Borrowing of the Type resulting from
     such election to be made on the effective date of such election. Each such
     telephonic Interest Election Request shall be irrevocable and


                                       24



     shall be confirmed promptly by hand delivery or telecopy to the
     Administrative Agent of a written Interest Election Request in a form
     approved by the Administrative Agent and signed by the Borrower.

          (c) Each telephonic and written Interest Election Request shall
     specify the following information in compliance with Section 2.2:

               (i) the Borrowing to which such Interest Election Request applies
          and, if different options are being elected with respect to different
          portions thereof, the portions thereof to be allocated to each
          resulting Borrowing (in which case the information to be specified
          pursuant to clauses (iii) and (iv) below shall be specified for each
          resulting Borrowing);

               (ii) the effective date of the election made pursuant to such
          Interest Election Request, which shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing
          or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the
          Interest Period to be applicable thereto after giving effect to such
          election, which shall be a period contemplated by the definition of
          the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

          (d) Promptly following receipt of an Interest Election Request, the
     Administrative Agent shall advise each Lender of the details thereof and of
     such Lender's portion of each resulting Borrowing.

          (e) If the Borrower fails to deliver a timely Interest Election
     Request with respect to a Eurodollar Revolving Borrowing prior to the end
     of the Interest Period applicable thereto, then, unless such Borrowing is
     repaid as provided herein, at the end of such Interest Period such
     Borrowing shall be converted to an ABR Borrowing. Notwithstanding any
     contrary provision hereof, if an Event of Default has occurred and is
     continuing and the Administrative Agent, at the request of the Required
     Lenders, so notifies the Borrower, then, so long as an Event of Default is
     continuing (i) no outstanding Revolving Borrowing may be converted to or
     continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar
     Revolving Borrowing shall be converted to an ABR Borrowing at the end of
     the Interest Period applicable thereto.

     SECTION 2.8. Termination and Reduction of Commitments. (a) Unless
previously terminated, the Commitments shall terminate on the Maturity Date.

          (b) The Borrower may at any time terminate, or from time to time
     reduce, the Commitments; provided that (i) each reduction of the
     Commitments shall be in an amount that is an integral multiple of $500,000
     and not less than $2,000,000 and (ii) the


                                       25



     Borrower shall not terminate or reduce the Commitments if, after giving
     effect to any concurrent prepayment of the Loans in accordance with Section
     2.10, the aggregate Revolving Credit Exposures of all Lenders would exceed
     the total Commitments.

          (c) The Borrower shall notify the Administrative Agent of any election
     to terminate or reduce the Commitments under paragraph (b) of this Section
     at least three Business Days prior to the effective date of such
     termination or reduction, specifying such election and the effective date
     thereof. Promptly following receipt of any notice, the Administrative Agent
     shall advise the Lenders of the contents thereof. Each notice delivered by
     the Borrower pursuant to this Section shall be irrevocable; provided that a
     notice of termination of the Commitments delivered by the Borrower may
     state that such notice is conditioned upon the effectiveness of other
     credit facilities, in which case such notice may be revoked by the Borrower
     (by notice to the Administrative Agent on or prior to the specified
     effective date) if such condition is not satisfied. Any termination or
     reduction of the Commitments shall be permanent but shall not affect the
     right of the Borrower to increase the Commitment in accordance with Section
     2.19. Each reduction of the Commitments shall be made ratably among the
     Lenders in accordance with their respective Commitments.

     SECTION 2.9. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby
unconditionally promises to pay (i) to the Administrative Agent for the account
of each Lender the then unpaid principal amount of each Revolving Loan on the
Maturity Date and (ii) to the Swingline Lender the then unpaid principal amount
of each Swingline Loan on the earlier of the Maturity Date and the first date
after such Swingline Loan is made that is the 15th or last day of a calendar
month and is at least two Business Days after such Swingline Loan is made;
provided that on each date that a Revolving Borrowing is made, the Borrower
shall repay all Swingline Loans then outstanding. On the Maturity Date, all
Loans shall become absolutely due and payable and the Borrower shall pay all of
the Loans outstanding, together with any and all accrued and unpaid interest
thereon.

          (b) Each Lender shall 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.

          (c) The Administrative Agent shall maintain accounts in which it shall
     record (i) the amount of each Loan made hereunder, the Class and Type
     thereof and the Interest Period applicable thereto, (ii) the amount of any
     principal or interest due and payable or to become due and payable from the
     Borrower to each Lender hereunder and (iii) the amount of any sum received
     by the Administrative Agent hereunder for the account of the Lenders and
     each Lender's share thereof.

          (d) The entries made in the accounts maintained pursuant to paragraph
     (b) or (c) of this Section shall be prima facie evidence of the existence
     and amounts of the obligations recorded therein; provided that the failure
     of any Lender or the Administrative Agent to maintain such accounts or any
     error therein shall not in any


                                       26



     manner affect the obligation of the Borrower to repay the Loans in
     accordance with the terms of this Agreement.

          (e) Any Lender may request that Loans made by it be evidenced by a
     promissory note. In such event, the Borrower shall prepare, execute and
     deliver to such Lender a promissory note payable to the order of such
     Lender (or, if requested by such Lender, to such Lender and its registered
     assigns) and in a form approved by the Administrative Agent. Thereafter,
     the Loans evidenced by such promissory note and interest thereon shall at
     all times (including after assignment pursuant to Section 9.4) be
     represented by one or more promissory notes in such form payable to the
     order of the payee named therein (or, if such promissory note is a
     registered note, to such payee and its registered assigns).

     SECTION 2.10. Prepayment of Loans. (a) The Borrower shall have the right at
any time and from time to time to prepay any Borrowing in whole or in part,
subject to prior notice in accordance with paragraph (b) of this Section.

          (b) The Borrower shall notify the Administrative Agent (and, in the
     case of prepayment of a Swingline Loan, the Swingline Lender) by telephone
     (confirmed by telecopy) of any prepayment hereunder (i) in the case of
     prepayment of a Eurodollar Revolving Borrowing, not later than 11:00 a.m.,
     New York City time, three Business Days before the date of prepayment, (ii)
     in the case of prepayment of an ABR Revolving Borrowing, not later than
     11:00 a.m., New York City time, one Business Day before the date of
     prepayment or (iii) in the case of prepayment of a Swingline Loan, not
     later than 12:00 noon, New York City time, on the date of prepayment. Each
     such notice shall be irrevocable and shall specify the prepayment date and
     the principal amount of each Borrowing or portion thereof to be prepaid;
     provided that if a notice of prepayment is given in connection with a
     conditional notice of termination of the Commitments as contemplated by
     Section 2.8, then such notice of prepayment may be revoked if such notice
     of termination is revoked in accordance with Section 2.8. Promptly
     following receipt of any such notice relating to a Revolving Borrowing, the
     Administrative Agent shall advise the Lenders of the contents thereof. Each
     partial prepayment of any Revolving Borrowing shall be in an amount that
     would be permitted in the case of an advance of a Revolving Borrowing of
     the same Type as provided in Section 2.2. Each prepayment of a Revolving
     Borrowing shall be applied ratably to the Loans included in the prepaid
     Borrowing. Prepayments shall be accompanied by accrued interest to the
     extent required by Section 2.12.

     SECTION 2.11. Fees. (a) The Borrower agrees to pay to the Administrative
Agent for the account of each Lender a commitment fee, which shall accrue daily
at the rates set forth below (calculated in accordance with the definition of
"Applicable Rate") on such Lender's unused Commitment (less such Lender's
Applicable Percentage of the average daily balance of Letters of Credit), during
the period from and including the Effective Date to but excluding the date on
which such Commitment terminates; provided that if such Lender continues to have
any Revolving Credit Exposure after its Commitment terminates with respect
thereto, then such commitment fee shall continue to accrue on the daily amount
of such Lender's Swingline


                                       27



Exposure and LC Exposure from and including the date on which its Commitment
terminates to but excluding the date on which such Lender ceases to have any
Revolving Credit Exposure:



Pricing Level    Leverage Ratio:                        Commitment Fee
- -------------   -----------------                       --------------
                                                  
1               < 0.50:1.00                                 0.125%
2               greater than equal to 0.50:1.00 and <       0.150%
                1.00:1.00
3               greater than equal to 1.00:1.00 and <       0.175%
                1.50:1.00
4               greater than equal to 1.50:1.00 and <       0.200%
                2.00:1.00
5               greater than equal to 2.00:1.00             0.300%


Accrued commitment fees shall be payable in arrears on the last day of March,
June, September and December of each year and on the date on which the
Commitments terminate, commencing on the first such date to occur after the date
hereof; provided that any commitment fees accruing after the date on which the
Commitments terminate shall be payable on demand. All commitment fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (b) The Borrower agrees to pay (i) to the Administrative Agent for the
     account of each Lender a participation fee with respect to its
     participations in Letters of Credit, which shall accrue at the same
     Applicable Rate used to determine the interest rate applicable to
     Eurodollar Revolving Loans on the average daily amount of such Lender's LC
     Exposure (excluding any portion thereof attributable to unreimbursed LC
     Disbursements) during the period from and including the Effective Date to
     but excluding the later of the date on which such Lender's Commitment
     terminates and the date on which such Lender ceases to have any LC
     Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue
     at the rate or rates per annum separately agreed upon between the Borrower
     and the Issuing Bank on the average daily amount of the LC Exposure
     (excluding any portion thereof attributable to unreimbursed LC
     Disbursements) during the period from and including the Effective Date to
     but excluding the later of the date of termination of the Commitments and
     the date on which there ceases to be any LC Exposure, as well as the
     Issuing Bank's standard fees with respect to the issuance, amendment,
     renewal or extension of any Letter of Credit or processing of drawings
     thereunder. Participation fees and fronting fees accrued through and
     including the last day of March, June, September and December of each year
     shall be payable on the third Business Day following such last day,
     commencing on the first such date to occur after the Effective Date;
     provided that all such fees shall be payable on the date on which the
     Commitments terminate and any such fees accruing after the date on which
     the Commitments terminate shall be payable on demand. Any other fees
     payable to the Issuing Bank pursuant to this paragraph shall be payable
     within 10 days after demand.


                                       28




     All participation fees and fronting fees shall be computed on the basis of
     a year of 360 days and shall be payable for the actual number of days
     elapsed (including the first day but excluding the last day).

          (c) The Borrower agrees to pay to the Administrative Agent or the Lead
     Arranger, for its own account, fees payable in the amounts and at the times
     provided in the Fee Letter or as separately agreed upon from time to time
     between the Borrower and the Administrative Agent and/or the Lead Arranger.

          (d) All fees payable hereunder shall be paid on the dates due, in
     immediately available funds, to the Administrative Agent (or to the Issuing
     Bank, in the case of fees payable to it) for distribution, in the case of
     commitment fees and participation fees, to the Lenders. Fees paid shall not
     be refundable under any circumstances (unless miscalculated).

     SECTION 2.12. Interest. (a) The Loans comprising each ABR Borrowing shall
bear interest at the Alternate Base Rate plus the Applicable Rate.

          (b) The Loans comprising each Eurodollar Borrowing shall bear interest
     at the Adjusted LIBO Rate for the Interest Period in effect for such
     Borrowing plus the Applicable Rate.

          (c) Notwithstanding the foregoing, if any principal of or interest on
     any Loan or any fee or other amount payable by the Borrower hereunder is
     not paid when due, whether at stated maturity, upon acceleration or
     otherwise, such overdue amount shall bear interest, after as well as before
     judgment, at a rate per annum equal to (i) in the case of overdue principal
     of any Loan, 2% plus the rate otherwise applicable to such Loan as provided
     in the preceding paragraphs of this Section or (ii) in the case of any
     other amount, 2% plus the rate applicable to ABR Loans as provided in
     paragraph (a) of this Section.

          (d) Accrued interest on each Loan shall be payable in arrears on each
     Interest Payment Date for such Loan and, in the case of Revolving Loans,
     upon termination of the Commitments; provided that (i) interest accrued
     pursuant to paragraph (c) of this Section shall be payable on demand, (ii)
     in the event of any repayment or prepayment of any Loan (other than a
     prepayment of an ABR Revolving Loan prior to the end of the Availability
     Period), accrued interest on the principal amount repaid or prepaid shall
     be payable on the date of such repayment or prepayment and (iii) in the
     event of any conversion of any Eurodollar Revolving Loan prior to the end
     of the current Interest Period therefor, accrued interest on such Loan
     shall be payable on the effective date of such conversion.

          (e) All interest hereunder shall be computed on the basis of a year of
     360 days, except that interest computed by reference to the Alternate Base
     Rate at times when the Alternate Base Rate is based on the Prime Rate shall
     be computed on the basis of a year of 365 days (or 366 days in a leap
     year), and in each case shall be payable for the actual number of days
     elapsed (including the first day but excluding the last day). The


                                       29



     applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be
     determined by the Administrative Agent, and such determination shall be
     conclusive absent manifest error.

     SECTION 2.13. Alternate Rate of Interest. If prior to the commencement of
any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be
     conclusive absent manifest error) that adequate and reasonable means do not
     exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as
     applicable, for such Interest Period; or

          (b) the Administrative Agent is advised by the Required Lenders that
     the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest
     Period will not adequately and fairly reflect the cost to such Lenders (or
     Lender) of making or maintaining their Loans (or its Loan) included in such
     Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Revolving Borrowing to, or
continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be
ineffective, and (ii) if any Borrowing Request requests a Eurodollar Revolving
Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that if
the circumstances giving rise to such notice affect only one Type of Borrowings,
then the other Type of Borrowings shall be permitted.

     SECTION 2.14. Increased Costs. (a) If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
          deposit or similar requirement against assets of, deposits with or for
          the account of, or credit extended by, any Lender (except any such
          reserve requirement reflected in the Adjusted LIBO Rate) or the
          Issuing Bank; or

               (ii) impose on any Lender or the Issuing Bank or the London
          interbank market any other condition affecting this Agreement or
          Eurodollar Loans made by such Lender or any Letter of Credit or
          participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the
Issuing Bank of participating in, issuing or maintaining any Letter of Credit or
to reduce the amount of any sum received or receivable by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such
additional amount or amounts as will compensate such Lender or the Issuing Bank,
as the case may be, for such additional costs incurred or reduction suffered.


                                       30



          (b) If any Lender or the Issuing Bank determines (absent manifest
     error) that any Change in Law regarding capital requirements has or would
     have the effect of reducing the rate of return on such Lender's or the
     Issuing Bank's capital or on the capital of such Lender's or the Issuing
     Bank's holding company, if any, as a consequence of this Agreement or the
     Loans made by, or participations in Letters of Credit held by, such Lender,
     or the Letters of Credit issued by the Issuing Bank, to a level below that
     which such Lender or the Issuing Bank or such Lender's or the Issuing
     Bank's holding company could have achieved but for such Change in Law
     (taking into consideration such Lender's or the Issuing Bank's policies and
     the policies of such Lender's or the Issuing Bank's holding company with
     respect to capital adequacy), then from time to time the Borrower will pay
     to such Lender or the Issuing Bank, as the case may be, such additional
     amount or amounts as will compensate such Lender or the Issuing Bank or
     such Lender's or the Issuing Bank's holding company for any such reduction
     suffered.

          (c) A certificate of a Lender or the Issuing Bank setting forth the
     amount or amounts necessary to compensate such Lender or the Issuing Bank
     or its holding company, as the case may be, as specified in paragraph (a)
     or (b) of this Section shall be delivered to the Borrower and shall be
     conclusive absent manifest error. The Borrower shall pay such Lender or the
     Issuing Bank, as the case may be, the amount shown as due on any such
     certificate within 10 days after receipt thereof.

          (d) Failure or delay on the part of any Lender or the Issuing Bank to
     demand compensation pursuant to this Section shall not constitute a waiver
     of such Lender's or the Issuing Bank's right to demand such compensation;
     provided that the Borrower shall not be required to compensate a Lender or
     the Issuing Bank pursuant to this Section for any increased costs or
     reductions incurred more than 180 days prior to the date that such Lender
     or the Issuing Bank, as the case may be, notifies the Borrower of the
     Change in Law giving rise to such increased costs or reductions and of such
     Lender's or the Issuing Bank's intention to claim compensation therefor;
     provided further that if the Change in Law giving rise to such increased
     costs or reductions is retroactive, then the 180-day period referred to
     above shall be extended to include the period of retroactive effect
     thereof.

     SECTION 2.15. Break Funding Payments. In the event of (a) the payment of
any principal of any Eurodollar Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Eurodollar Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice may be revoked under Section
2.10(b) and is revoked in accordance therewith), or (d) the assignment of any
Eurodollar Loan other than on the last day of the Interest Period applicable
thereto as a result of a request by the Borrower pursuant to Section 2.18, then,
in any such event, the Borrower shall compensate each Lender for the actual
loss, cost and expense attributable to such event. In the case of a Eurodollar
Loan, such loss, cost or expense to any Lender shall be deemed to include an
amount determined by such Lender to be the excess, if any, of (i) the amount of
interest which would have accrued on the principal amount of such Loan had such
event not occurred, at the Adjusted LIBO Rate (and without reference to the
Applicable Margin) that would have been applicable to such Loan, for


                                       31



the period from the date of such event to the last day of the then current
Interest Period therefor (or, in the case of a failure to borrow, convert or
continue, for the period that would have been the Interest Period for such
Loan), over (ii) the amount of interest which would accrue on such principal
amount for such period at the interest rate which such Lender would bid were it
to bid, at the commencement of such period, for dollar deposits of a comparable
amount and period from other banks in the eurodollar market. A certificate of
any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

     SECTION 2.16. Taxes. (a) Any and all payments by or on account of any
obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or
Issuing Bank (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay any Other Taxes to the
     relevant Governmental Authority in accordance with applicable law.

          (c) The Borrower shall indemnify the Administrative Agent, each Lender
     and the Issuing Bank, within 10 days after written demand therefor, for the
     full amount of any Indemnified Taxes or Other Taxes paid by the
     Administrative Agent, such Lender or the Issuing Bank, as the case may be,
     on or with respect to any payment by or on account of any obligation of the
     Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
     asserted on or attributable to amounts payable under this Section) and any
     penalties, interest and reasonable expenses arising therefrom or with
     respect thereto, whether or not such Indemnified Taxes or Other Taxes were
     correctly or legally imposed or asserted by the relevant Governmental
     Authority. A certificate as to the amount of such payment or liability
     delivered to the Borrower by a Lender or the Issuing Bank, or by the
     Administrative Agent on its own behalf or on behalf of a Lender or the
     Issuing Bank, shall be conclusive absent manifest error.

          (d) As soon as practicable after any payment of Indemnified Taxes or
     Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
     deliver to the Administrative Agent the original or a certified copy of a
     receipt issued by such Governmental Authority evidencing such payment, a
     copy of the return reporting such payment or other evidence of such payment
     reasonably satisfactory to the Administrative Agent.

          (e) Any Foreign Lender that is entitled to an exemption from or
     reduction of withholding tax under the law of the jurisdiction in which the
     Borrower is located, or any treaty to which such jurisdiction is a party,
     with respect to payments under this


                                       32



     Agreement shall deliver to the Borrower (with a copy to the Administrative
     Agent), at the time or times prescribed by applicable law, such properly
     completed and executed documentation prescribed by applicable law or
     reasonably requested by the Borrower as will permit such payments to be
     made without withholding or at a reduced rate.

          (f) If the Administrative Agent or a Lender determines, in its sole
     discretion, that it has received a refund of any Taxes or Other Taxes as to
     which it has been indemnified by the Borrower or with respect to which the
     Borrower has paid additional amounts pursuant to this Section 2.16, it
     shall pay over such refund to the Borrower (but only to the extent of
     indemnity payments made, or additional amounts paid, by the Borrower under
     this Section 2.16 with respect to the Taxes or Other Taxes giving rise to
     such refund), net of all out-of-pocket expenses of the Administrative Agent
     or such Lender and without interest (other than any interest paid by the
     relevant Governmental Authority with respect to such refund); provided,
     that the Borrower, upon the request of the Administrative Agent or such
     Lender, agrees to repay the amount paid over to the Borrower (plus any
     penalties, interest or other charges imposed by the relevant Governmental
     Authority) to the Administrative Agent or such Lender in the event the
     Administrative Agent or such Lender is required to repay such refund to
     such Governmental Authority. This Section shall not be construed to require
     the Administrative Agent or any Lender to make available its tax returns
     (or any other information relating to its taxes which it deems
     confidential) to the Borrower or any other Person.

     SECTION 2.17. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
(a) The Borrower shall make each payment required to be made by it hereunder
(whether of principal, interest, fees or reimbursement of LC Disbursements, or
of amounts payable under Section 2.14, 2.15 or 2.16, or otherwise) prior to
12:00 noon, New York City time, on the date when due, in immediately available
funds, without set-off or counterclaim. Any amounts received after such time on
any date may, in the discretion of the Administrative Agent, be deemed to have
been received on the next succeeding Business Day for purposes of calculating
interest thereon. All such payments shall be made to the Administrative Agent at
its offices at 270 Park Avenue, New York, New York, except payments to be made
directly to the Issuing Bank or Swingline Lender as expressly provided herein
and except that payments pursuant to Sections 2.14, 2.15, 2.16 and 9.3 shall be
made directly to the Persons entitled thereto. The Administrative Agent shall
distribute any such payments received by it for the account of any other Person
to the appropriate recipient promptly following receipt thereof. If any payment
hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and, in the case of any
payment accruing interest, interest thereon shall be payable for the period of
such extension. All payments hereunder shall be made in dollars.

          (b) If at any time insufficient funds are received by and available to
     the Administrative Agent to pay fully all amounts of principal,
     unreimbursed LC Disbursements, interest and fees then due hereunder, such
     funds shall be applied (i) first, towards payment of interest and fees then
     due hereunder, ratably among the parties entitled thereto in accordance
     with the amounts of interest and fees then due to such parties, and (ii)
     second, towards payment of principal and unreimbursed LC Disbursements then
     due hereunder, ratably among the parties entitled thereto in


                                       33



     accordance with the amounts of principal and unreimbursed LC Disbursements
     then due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or
     counterclaim or otherwise, obtain payment in respect of any principal of or
     interest on any of its Revolving Loans or participations in LC
     Disbursements or Swingline Loans resulting in such Lender receiving payment
     of a greater proportion of the aggregate amount of its Revolving Loans and
     participations in LC Disbursements and Swingline Loans and accrued interest
     thereon than the proportion received by any other Lender, then the Lender
     receiving such greater proportion shall purchase (for cash at face value)
     participations in the Revolving Loans and participations in LC
     Disbursements and Swingline Loans of other Lenders to the extent necessary
     so that the benefit of all such payments shall be shared by the Lenders
     ratably in accordance with the aggregate amount of principal of and accrued
     interest on their respective Revolving Loans and participations in LC
     Disbursements and Swingline Loans; provided that (i) if any such
     participations are purchased and all or any portion of the payment giving
     rise thereto is recovered, such participations shall be rescinded and the
     purchase price restored to the extent of such recovery, without interest,
     and (ii) the provisions of this paragraph shall not be construed to apply
     to any payment made by the Borrower pursuant to and in accordance with the
     express terms of this Agreement or any payment obtained by a Lender as
     consideration for the assignment of or sale of a participation in any of
     its Loans or participations in LC Disbursements to any assignee or
     participant, other than to the Borrower or any Subsidiary or Affiliate
     thereof (as to which the provisions of this paragraph shall apply). The
     Borrower consents to the foregoing and agrees, to the extent it may
     effectively do so under applicable law, that any Lender acquiring a
     participation pursuant to the foregoing arrangements may exercise against
     the Borrower rights of set-off and counterclaim with respect to such
     participation as fully as if such Lender were a direct creditor of the
     Borrower in the amount of such participation.

          (d) Unless the Administrative Agent shall have received notice from
     the Borrower prior to the date on which any payment is due to the
     Administrative Agent for the account of the Lenders or the Issuing Bank
     hereunder that the Borrower will not make such payment, the Administrative
     Agent may assume that the Borrower has made such payment on such date in
     accordance herewith and may, in reliance upon such assumption, distribute
     to the Lenders or the Issuing Bank, as the case may be, the amount due. In
     such event, if the Borrower has not in fact made such payment, then each of
     the Lenders or the Issuing Bank, as the case may be, severally agrees to
     repay to the Administrative Agent forthwith on demand the amount so
     distributed to such Lender or Issuing Bank with interest thereon, for each
     day from and including the date such amount is distributed to it to but
     excluding the date of payment to the Administrative Agent, at the greater
     of the Federal Funds Effective Rate and a rate determined by the
     Administrative Agent in accordance with banking industry rules on interbank
     compensation.

          (e) If any Lender shall fail to make any payment required to be made
     by it pursuant to Section 2.4(c), 2.5(d) or (e), 2.6(b), 2.17(d) or 9.3(c),
     then the Administrative Agent may, in its discretion (notwithstanding any
     contrary provision hereof), apply any amounts thereafter received by the
     Administrative Agent for the account of such Lender


                                       34



     to satisfy such Lender's obligations under such Sections until all such
     unsatisfied obligations are fully paid.

     SECTION 2.18. Mitigation Obligations; Replacement of Lenders. (a) If any
Lender requests compensation under Section 2.14, or if the Borrower is required
to pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to Section 2.16, then such Lender shall use
reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its rights and obligations hereunder to
another of its offices, branches or affiliates, if, in the judgment of such
Lender, such designation or assignment (i) would eliminate or reduce amounts
payable pursuant to Section 2.14 or 2.16, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to
pay all reasonable costs and expenses incurred by any Lender in connection with
any such designation or assignment.

          (b) If any Lender requests compensation under Section 2.14, or if the
     Borrower is required to pay any additional amount to any Lender or any
     Governmental Authority for the account of any Lender pursuant to Section
     2.16, or if any Lender defaults in its obligation to fund Loans hereunder,
     then the Borrower may, at its sole expense and effort, upon notice to such
     Lender and the Administrative Agent, require such Lender to assign and
     delegate, without recourse (in accordance with and subject to the
     restrictions contained in Section 9.4), all its interests, rights and
     obligations under this Agreement to an assignee that shall assume such
     obligations (which assignee may be another Lender, if a Lender accepts such
     assignment); provided that (i) the Borrower shall have received the prior
     written consent of the Administrative Agent (and if a Commitment is being
     assigned, the Issuing Bank), which consent shall not unreasonably be
     withheld, (ii) such Lender shall have received payment of an amount equal
     to the outstanding principal of its Loans and funded participations in LC
     Disbursements and Swingline Loans, accrued interest thereon, accrued fees
     and all other amounts payable to it hereunder, from the assignee (to the
     extent of such outstanding principal and accrued interest and fees) or the
     Borrower (in the case of all other amounts) and (iii) in the case of any
     such assignment resulting from a claim for compensation under Section 2.14
     or payments required to be made pursuant to Section 2.16, such assignment
     will result in a reduction in such compensation or payments. A Lender shall
     not be required to make any such assignment and delegation if, within five
     Business Days after being notified that the Borrower proposes to require a
     Lender to make such assignment and delegation hereunder, as a result of a
     waiver by such Lender or otherwise, the circumstances entitling the
     Borrower to require such assignment and delegation cease to apply.

     SECTION 2.19. Increase in Commitments. The Borrower shall have the right
upon one or more occasions by written notice to the Administrative Agent (a
"Commitment Increase Notice") to request an increase in the aggregate Commitment
(the amount of increase requested on any occasion being referred to herein as
the "Increase Amount"), to a maximum aggregate Commitment of $150,000,000;
provided that at the time of the Commitment Increase Notice and at the time such
request would become effective (i) no Default has occurred and is continuing or
would exist after giving effect to such increase in the Commitment, and (ii) the
Borrower will be in pro forma compliance with all of the covenants of Section
6.9 after giving effect to such


                                       35



increase in the Commitment. The Commitment Increase Notice shall be delivered by
the Agent to the Lenders and shall specify a time period selected by the
Borrower within which each Lender is requested to respond to such Commitment
Increase Notice (which shall in no event be less than ten Business Days from the
date of delivery of such Commitment Increase Notice to the Lenders). Each Lender
shall notify the Administrative Agent within such time period whether or not it
agrees to increase its Commitment and, if so, whether by an amount equal to,
greater than, or less than its Applicable Percentage of such requested increase.
Any such Lender not responding within such time period shall be deemed to have
declined to increase its Commitment. The Administrative Agent shall notify the
Borrower and each Lender of such other Lender's responses to each request made
hereunder. After the expiration of the time period set forth in the Commitment
Increase Notice or receipt by the Administrative Agent of responses to the
Commitment Increase Notice from each of the Lenders, then the Borrower may, to
achieve the full amount of the requested increase in the Commitments, invite one
or more other Persons (other than individuals) (an "Additional Lender") that
have agreed to provide the Increase Amount and that are acceptable to each of
the Administrative Agent, Swingline Lender and Issuing Bank (such consent not to
be unreasonably withheld) (it being agreed that any Lender as of the date of the
Commitment Increase Notice would be acceptable) may be admitted as a Lender
party to this Agreement in accordance with the provisions of Section 9.4(e).
None of the Administrative Agent, Lead Arranger or any other Lender shall have
any obligation or other commitment to provide all or any portion of the Increase
Amount. Any such increase in the Commitment shall become effective upon written
notice by the Administrative Agent (which shall be promptly delivered by the
Administrative Agent) to the Borrower and the Lenders specifying the effective
date of such increase in Commitment, together with a revised Schedule 2.1
stating the new Commitment, and, in respect thereof, the Commitment Amount of
each Additional Lender, the respective continuing Commitment amount of the other
Lenders and the new Revolving Credit Exposure of the Lenders. Upon the effective
date of the increased Commitment, each Additional Lender shall make all (if any)
such payments to the Administrative Agent for distribution to the other Lenders
as may be necessary to result in the respective Revolving Loans held by such
Additional Lender and the other Lenders being equal to such applicable Lender's
Revolving Credit Exposure (as set forth in the revised Schedule 2.1) of the
aggregate principal amount of all Revolving Loans outstanding as of such date.
The Borrower hereby agrees that any Additional Lender so paying any such amount
to the other Lenders pursuant to the preceding sentence shall be entitled to all
the rights of a Lender having Commitments hereunder in respect of such amounts,
that such payments to such other Lenders shall thereafter constitute Revolving
Loans made by such Additional Lender hereunder and that such Additional Lender
may exercise all of its right of payment with respect to such amounts as fully
as if such Additional Lender had initially advanced to the Borrower directly the
amount of such payments. If any such adjustment payments pursuant to the
preceding sentences of this Section 2.19 are made by an Additional Lender to
other Lenders at a time other than the end of an Interest Period in the case of
all or any portion of Revolving Loans constituting Eurodollar Loans, the
Borrower shall pay to each of the Lenders receiving any such payment, at the
time that such payment is made pursuant to this Section 2.19, the amount that
would be required to be paid by the Borrower pursuant to Section 2.15 had such
payments been made directly by the Borrower.


                                       36


                                  ARTICLE III.
                         REPRESENTATIONS AND WARRANTIES

     Each Loan Party represents and warrants to the Lenders that:

     SECTION 3.1. Organization; Powers. The Borrower and each Material
Subsidiary is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization and has all requisite power and
authority to carry on its business as now conducted. Each Subsidiary other than
a Material Subsidiary is duly organized, validly existing and in good standing
under the laws of the jurisdiction of its organization and has all requisite
power and authority to carry on its business as now conducted, except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. Except where the failure to do
so, individually or in the aggregate, could not reasonably be expected to result
in a Material Adverse Effect, the Borrower and each Subsidiary is qualified to
do business in, and is in good standing in, every jurisdiction where such
qualification is required.

     SECTION 3.2. Authorization; Enforceability. The Transactions are within
each Loan Party's corporate powers and have been duly authorized by all
necessary corporate and, if required, stockholder action. This Agreement has
been duly executed and delivered by each Loan Party and constitutes a legal,
valid and binding obligation of each Loan Party, enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally and subject to
general principles of equity, regardless of whether considered in a proceeding
in equity or at law.

     SECTION 3.3. Governmental Approvals; No Conflicts. The Transactions (a) do
not require any consent or approval of, registration or filing with, or any
other action by, any Governmental Authority, except such as have been obtained
or made and are in full force and effect, (b) will not violate any applicable
law or regulation or the charter, by-laws or other organizational documents of
the Borrower or any of its Subsidiaries or any order of any Governmental
Authority, (c) will not violate or result in a default under any indenture,
agreement or other instrument binding upon the Borrower or any of its
Subsidiaries or its assets, or give rise to a right thereunder to require any
payment to be made by the Borrower or any of its Subsidiaries, and (d) will not
result in the creation or imposition of any Lien on any asset of the Borrower or
any of its Subsidiaries.

     SECTION 3.4. Financial Condition; No Material Adverse Change. (a) The
Borrower has heretofore furnished to the Lenders its consolidated balance sheet
and statements of income, stockholders equity and cash flows (i) as of and for
the fiscal year ended June 30, 2006, reported on by Ernst & Young LLP,
independent public accountants, and (ii) as of and for the fiscal quarter and
the portion of the fiscal year ended September 30, 2006, certified by its chief
financial officer. Such financial statements present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Borrower and its consolidated Subsidiaries as of such dates and for such periods
in accordance with GAAP, subject to year-end audit adjustments and the absence
of footnotes in the case of the statements referred to in clause (ii) above.


                                       37



          (b) Since June 30, 2006, there has been no material adverse change in
     the business, assets, operations, prospects or condition, financial or
     otherwise, of the Borrower and its Subsidiaries, taken as a whole.

     SECTION 3.5. Properties. (a) Each of the Borrower and its Subsidiaries has
good title to, or valid leasehold interests in, all its real and personal
property material to its business, except for minor defects in title that do not
interfere with its ability to conduct its business as currently conducted or to
utilize such properties for their intended purposes.

          (b) Each of the Borrower and its Subsidiaries owns, or is licensed to
     use, all trademarks, tradenames, copyrights, patents and other intellectual
     property material to its business, and the use thereof by the Borrower and
     its Subsidiaries does not infringe upon the rights of any other Person,
     except for any such infringements that, individually or in the aggregate,
     could not reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.6. Litigation and Environmental Matters. (a) There are no
actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of any Loan Party, threatened
against or affecting the Borrower or any of its Subsidiaries (i) that would
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve
this Agreement or the Transactions.

          (b) Except for the Disclosed Matters and except with respect to any
     other matters that, individually or in the aggregate, could not reasonably
     be expected to result in a Material Adverse Effect, neither the Borrower
     nor any of its Subsidiaries (i) has failed to comply with any Environmental
     Law or to obtain, maintain or comply with any permit, license or other
     approval required under any Environmental Law, (ii) has become subject to
     any Environmental Liability, (iii) has received notice of any claim with
     respect to any Environmental Liability or (iv) knows of any basis for any
     Environmental Liability.

          (c) Since the date of this Agreement, there has been no change in the
     status of the Disclosed Matters that, individually or in the aggregate, has
     resulted in, or materially increased the likelihood of, a Material Adverse
     Effect.

     SECTION 3.7. Compliance with Laws and Agreements. Each of the Borrower and
its Subsidiaries is in compliance with all laws, regulations and orders of any
Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No Default has occurred and is
continuing.

     SECTION 3.8. Investment and Holding Company Status. Neither the Borrower
nor any of its Subsidiaries is (a) an "investment company" as defined in, or
subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 2005.


                                       38



     SECTION 3.9. Taxes. Each of the Borrower and its Subsidiaries has timely
filed or caused to be filed all Tax returns and reports required to have been
filed (within any applicable extension) and has paid or caused to be paid all
Taxes required to have been paid by it, except (a) Taxes that are being
contested in good faith by appropriate proceedings and for which the Borrower or
such Subsidiary, as applicable, has set aside on its books adequate reserves or
(b) to the extent that the failure to do so could not reasonably be expected to
result in a Material Adverse Effect.

     SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably expected
to occur that, when taken together with all other such ERISA Events for which
liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date
of the most recent financial statements reflecting such amounts, exceed the fair
market value of the assets of such Plan, and the present value of all
accumulated benefit obligations of all underfunded Plans (based on the
assumptions used for purposes of Statement of Financial Accounting Standards No.
87) did not, as of the date of the most recent financial statements reflecting
such amounts, exceed the fair market value of the assets of all such underfunded
Plans.

     SECTION 3.11. Disclosure. Neither the Information Memorandum nor any of the
other reports, financial statements, certificates or other information furnished
by or on behalf of any Loan Party to the Administrative Agent or any Lender in
connection with the negotiation of this Agreement or delivered hereunder (as
modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided that (a) with respect to projected financial
information, each Loan Party represents only that such information was prepared
in good faith based upon assumptions believed to be reasonable at the time, and
(b) to the extent the representations made in this Section 3.11 relate to CCT or
Behavioral and Medical Research, LLC, such representations are made to the best
of the knowledge of the each Loan Party.

     SECTION 3.12. Subsidiaries. As of the date hereof, Schedule 3.12 is a
complete list of each of the Borrower's Subsidiaries and such Subsidiary's
jurisdiction of incorporation.

     SECTION 3.13. Federal Regulations. Neither the Borrower nor any of its
Subsidiaries is engaged or will engage in any activities, nor shall use any
portion of the proceeds of the Loans be used for any purpose, which in either
case violate or are inconsistent with the provisions of Regulations U and X of
the Board of Governors of the Federal Reserve System as now and from time to
time hereafter in effect.

                                  ARTICLE IV.
                                   CONDITIONS

     quarters of each fiscal year of the Borrower, its consolidated balance
     sheet and related statements of operations, stockholders' equity and cash

     or proposed to be taken with respect thereto, (ii) setting forth reasonably
     detailed calculations demonstrating compliance with Section 6.9 and (iii)
     stating whether any change in GAAP or in the application thereof has
     occurred since the date of the audited financial statements referred to in

     such change on the financial statements accompanying such certificate;

          (d) promptly after the same become publicly available, copies of all
     periodic and other reports, proxy statements and other materials filed by

the Administrative Agent and the Lenders upon the filing of such items with the
Securities and Exchange Commission, provided that such items are readily
available for public viewing on EDGAR, or (ii) clause (c) of this Section by the
Borrower shall be deemed satisfied by delivery to the Administrative Agent of
such items for posting to Intralinks or other such similar system (to the extent
Intralinks or such other system has been established, is functioning and is
accessible to each Lender).

     SECTION 5.2. Notices of Material Events. The Borrower will furnish to the
Administrative Agent and each Lender prompt written notice of the following:

          (b) the filing or commencement of any action, suit or proceeding by or

          (d) any other development that results in, or could reasonably be
     expected to result in, a Material Adverse Effect.

Each notice delivered under this Section shall be accompanied by a statement of
a Financial Officer or other executive officer of the Borrower setting forth the
details of the event or development requiring such notice and any action taken
or proposed to be taken with respect thereto.

     SECTION 5.3. Existence; Conduct of Business. The Borrower will, and will
cause each of its Subsidiaries to, do or cause to be done all things necessary
to preserve, renew and keep in full force and effect its legal existence and the
rights, licenses, permits, privileges and franchises material to the conduct of
the business of the Borrower and its Subsidiaries, taken as a whole; provided
that the foregoing shall not prohibit any merger, consolidation, liquidation or
dissolution permitted under Section 6.3.

     SECTION 5.4. Payment of Obligations. The Borrower will, and will cause each
of its Subsidiaries to, pay its obligations, including Tax liabilities, that, if
not paid, could result in a Material Adverse Effect before the same shall become
delinquent or in default, except where (a) the validity or amount thereof is
being contested in good faith by appropriate proceedings, (b) the Borrower or
such Subsidiary has set aside on its books adequate reserves with respect
thereto in accordance with GAAP and (c) the failure to make payment pending such
contest could not reasonably be expected to result in a Material Adverse Effect.

will cause each of its Subsidiaries to, (a) keep and maintain all property
material to the conduct of the business of the Borrower and its Subsidiaries,
taken as a whole, in good working order and condition, ordinary wear and tear
excepted, and (b) maintain, with financially sound and reputable insurance
companies, insurance in such amounts and against such risks as are customarily
maintained by companies engaged in the same or similar businesses operating in
the same or similar locations.

     SECTION 5.6. Books and Records; Inspection Rights. The Borrower will, and
will cause each of its Subsidiaries to, keep proper books of record and account
in which full, true and correct entries are made of all dealings and
transactions in relation to its business and activities. The Borrower will, and
will cause each of its Subsidiaries to, permit any representatives designated by
the Administrative Agent or the Required Lenders, upon reasonable prior notice,
to visit and inspect its properties, to examine and make extracts from its books
and records, and to discuss its affairs, finances and condition with its
officers and independent accountants, all at such reasonable times and as often
as reasonably requested, provided that such visits shall not


                                       43



occur more than once per calendar year unless an Event of Default has occurred
and is continuing.

     SECTION 5.7. Compliance with Laws. The Borrower will, and will cause each
of its Subsidiaries to, comply with all laws, rules, regulations and orders of
any Governmental Authority applicable to it or its property, except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

     SECTION 5.8. Use of Proceeds and Letters of Credit. The proceeds of the
Loans will be used only (a) to finance Permitted Acquisitions; (b) to repay all
outstanding amounts under the Borrower's Advised Line Facility; (c) to finance
Permitted Stock Repurchases, and (d) for general corporate purposes of the
Borrower and its Subsidiaries. No part of the proceeds of any Loan will be used,
whether directly or indirectly, for any purpose that entails a violation of any
of the Regulations of the Board, including Regulations T, U and X.

     SECTION 5.9. Additional Subsidiaries. In the event the Borrower acquires or
creates any Material U.S. Subsidiaries or if any existing Subsidiary becomes a
Material U.S. Subsidiary after the Effective Date, the Borrower shall forthwith
promptly cause such Subsidiary to become a Subsidiary Guarantor; provided that,
at the reasonable discretion of the Administrative Agent, no such Material U.S.
Subsidiary shall be required to become a Subsidiary Guarantor to the extent that
doing so would be reasonably likely to cause material adverse tax consequences
to the Borrower and its Subsidiaries.

                                  ARTICLE VI.

     SECTION 6.8. Restrictive Agreements. The Borrower will not, and will not
permit any of its Subsidiaries to, directly or indirectly, enter into, incur or

create, incur or permit to exist any Lien upon any of its property or assets, or
(b) the ability of any Subsidiary to pay dividends or other distributions with
respect to any shares of its capital stock or to make or repay loans or advances

apply to restrictions and conditions imposed by law or by this Agreement, (ii)
the foregoing shall not apply to restrictions and conditions (x) existing on the

restriction or condition) or (y) pursuant to the provisions governing
Indebtedness permitted pursuant to clause (f) or (h) of Section 6.1, so long as
such restrictions are not more restrictive than any restriction in this
Agreement, (iii) the foregoing shall not apply to customary restrictions and
conditions contained in agreements relating to the sale of a Subsidiary pending
such sale, provided such restrictions and conditions apply only to the
Subsidiary that is to be sold and such sale is permitted hereunder, (iv) clause
(a) of the foregoing shall not apply to restrictions or conditions imposed by
any agreement relating to secured Indebtedness permitted by this Agreement if
such restrictions or conditions apply only to the property or assets securing
such Indebtedness; and (v) clause (a)


                                       48

     reduction for losses) from after September 30, 2006, plus 100% of all Net

     be (i) included in Consolidated EBITDA all Consolidated EBITDA attributable
     to any Person or business acquired by (and thereafter owned by) the
     Borrower or any Subsidiary of the Borrower during such period as if such
     Person or business had been acquired on the day before the first day of
     such period and (ii) excluded from such Consolidated EBITDA all
     Consolidated EBITDA attributable to any Person or business disposed of by
     the Borrower or any Subsidiary of the Borrower during such period as if

respective fiscal year ends without giving prior notice to the Administrative

                                  ARTICLE VIII.
                            THE ADMINISTRATIVE AGENT

     Each of the Lenders and the Issuing Bank hereby irrevocably appoints the
Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to
the Administrative Agent by the terms hereof, together with such actions and
powers as are reasonably incidental thereto.

     The bank serving as the Administrative Agent hereunder shall have the same
rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and such bank
and its Affiliates may accept deposits from, lend money to and generally engage
in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

     The Administrative Agent shall not have any duties or obligations except
those expressly set forth herein. Without limiting the generality of the
foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is
continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing as directed by the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.2), and (c) except as expressly set forth
herein, the Administrative Agent shall not have any duty to disclose, and shall
not be liable for the failure to disclose, any information relating to the
Borrower or any of its Subsidiaries that is communicated to or obtained by the
bank serving as Administrative Agent or any of its Affiliates in any capacity.
The Administrative Agent shall not be liable for any action taken or not taken
by it with the consent or at the request of the Required Lenders (or such other
number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.2) or in the absence of its own gross
negligence or willful misconduct. The Administrative Agent shall be deemed not
to have knowledge of any Default unless and until written notice thereof is
given to the Administrative Agent by the Borrower or a Lender, and the
Administrative Agent shall not be responsible for or have any duty to ascertain
or inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement, (ii) the contents of any certificate, report or
other document delivered hereunder or in connection herewith, (iii) the
performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein, (iv) the validity, enforceability, effectiveness or
genuineness of this Agreement or any other agreement, instrument or document, or
(v) the satisfaction of any


                                       52



condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon. The Administrative Agent may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

     The Administrative Agent may perform any and all its duties and exercise
its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such
resignation, the Required Lenders shall have the right, in consultation with the
Borrower, to appoint a successor. If no successor shall have been so appointed
by the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of its resignation, then
the retiring Administrative Agent may, on behalf of the Lenders and the Issuing
Bank, appoint a successor Administrative Agent which shall be a bank with an
office in New York, New York, or an Affiliate of any such bank. Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor,
such successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Borrower to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the Administrative Agent's
resignation hereunder, the provisions of this Article and Section 9.3 shall
continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative
Agent.

     Each Lender acknowledges that it has, independently and without reliance
upon the Administrative Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not


                                       53



taking action under or based upon this Agreement, any related agreement or any
document furnished hereunder or thereunder.

     The Lead Arranger shall have no duties, responsibilities or obligations to,
no authority to act for, any other party to this Agreement by virtue of its
status as Lead Arranger hereunder.

                                   ARTICLE IX.
                                  MISCELLANEOUS

     apply to notices pursuant


                                       54



     to Article II unless otherwise agreed by the Administrative Agent and the
     applicable Lender. The Administrative Agent or the Borrower may, in its
     discretion, agree to accept notices and other communications to it

     it; provided that approval of such procedures may be limited to particular

     hereto. All notices and other communications given to any party hereto in
     accordance with the provisions of this Agreement shall be deemed to have
     been given on the date of receipt.

     SECTION 9.2. Waivers; Amendments. (a) No failure or delay by the
Administrative Agent, the Issuing Bank or any Lender in exercising any right or
power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent, the Issuing Bank and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan or issuance of a Letter of Credit shall not be
construed as a waiver of any Default, regardless of whether the Administrative
Agent, any Lender or the Issuing Bank may have had notice or knowledge of such
Default at the time.

          (b) Neither this Agreement nor any provision hereof may be waived,
     amended or modified except pursuant to an agreement or agreements in
     writing entered into by the Borrower and the Required Lenders or by the
     Borrower and the Administrative Agent with the consent of the Required
     Lenders; provided that no such agreement shall (i) increase the Commitment
     of any Lender without the written consent of such Lender, (ii) reduce the
     principal amount of any Loan or LC Disbursement or reduce the rate of
     interest thereon, or reduce any fees payable hereunder, without the written
     consent of each Lender affected thereby, (iii) postpone the scheduled date
     of payment of the principal amount of any Loan or LC Disbursement, or any
     interest thereon, or any fees payable hereunder, or reduce the amount of,
     waive or excuse any such payment, or postpone the scheduled date of
     expiration of any Commitment, without the written consent of each Lender
     affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would
     alter the pro rata sharing of payments required thereby, without the
     written consent of each Lender, or (v) change any of the provisions of this
     Section or the definition of "Required Lenders" or any other provision
     hereof specifying the number or percentage of Lenders required to waive,
     amend or modify any rights hereunder or make any determination or grant any
     consent hereunder, without the written consent of each Lender; provided
     further that no such agreement shall amend, modify or otherwise affect the
     rights or duties of the Administrative Agent, the Issuing Bank or the
     Swingline Lender hereunder without the prior written consent of the
     Administrative Agent, the Issuing Bank or the Swingline Lender, as the case
     may be.

     SECTION 9.3. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay

and its Affiliates, including the reasonable fees, charges and disbursements of

credit facilities provided for herein, the preparation and administration of
this Agreement or any amendments, modifications or waivers of the provisions
hereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing
Bank in connection with the issuance, amendment, renewal or extension of any
Letter of Credit or any demand for payment thereunder and (iii) all
out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or
any Lender, including the fees, charges and disbursements of any counsel for the
Administrative Agent, the Issuing Bank or any Lender, in connection with the
enforcement or protection of its rights after a Default in connection with this
Agreement, including its rights under this Section, or in connection with the
Loans made or Letters of Credit issued hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit.

          (b) The Borrower shall indemnify the Administrative Agent, the Issuing
     Bank and each Lender, and each Related Party of any of the foregoing
     Persons (each such Person being called an "Indemnitee") against, and hold
     each Indemnitee harmless from, any and all losses, claims, damages,
     liabilities and related expenses, including the fees, charges and
     disbursements of any counsel for any Indemnitee, incurred by or asserted
     against any Indemnitee arising out of, in connection with, or as a result
     of (i) the execution or delivery of this Agreement or any agreement or
     instrument contemplated hereby, the performance by the parties hereto of
     their respective obligations hereunder or the consummation of the
     Transactions or any other transactions contemplated hereby, (ii) any Loan
     or Letter of Credit or the use of the proceeds therefrom (including any
     refusal by the Issuing Bank to honor a demand for payment under a Letter of
     Credit if the documents presented in connection with such demand do not
     strictly comply with the terms of such Letter of Credit), (iii) any actual
     or alleged presence or release of Hazardous Materials on or from any
     property owned or operated by the Borrower or any of its Subsidiaries, or
     any Environmental Liability related in any way to the Borrower or any of
     its Subsidiaries, or (iv) any actual or prospective claim, litigation,
     investigation or proceeding relating to any of the foregoing, whether based
     on contract, tort or any other theory and regardless of whether any
     Indemnitee is a party thereto; provided that such indemnity shall not, as
     to any Indemnitee, be available to the extent that such losses, claims,
     damages, liabilities or related expenses are determined by a court of
     competent jurisdiction by final and nonappealable judgment to have resulted
     from the gross negligence or willful misconduct of such Indemnitee.

          (c) To the extent that the Borrower fails to pay any amount required
     to be paid by it to the Administrative Agent, the Issuing Bank or the
     Swingline Lender under paragraph (a) or (b) of this Section, each Lender
     severally agrees to pay to the Administrative Agent, the Issuing Bank or
     the Swingline Lender, as the case may be, such Lender's Applicable
     Percentage (determined as of the time that the applicable unreimbursed
     expense or indemnity payment is sought) of such unpaid amount; provided
     that the unreimbursed expense or indemnified loss, claim, damage, liability
     or related


                                       56



     expense, as the case may be, was incurred by or asserted against the
     Administrative Agent, the Issuing Bank or the Swingline Lender in its
     capacity as such.

          (d) To the extent permitted by applicable law, the Borrower shall not
     assert, and hereby waives, any claim against any Indemnitee, on any theory
     of liability, for special, indirect, consequential or punitive damages (as
     opposed to direct or actual damages) arising out of, in connection with, or
     as a result of, this Agreement or any agreement or instrument contemplated
     hereby, the Transactions, any Loan or Letter of Credit or the use of the
     proceeds thereof.

          (e) All amounts due under this Section shall be payable promptly after
     written demand therefor.

     SECTION 9.4. Successors and Assigns. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby (including any Affiliate of
the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower
may not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment
or transfer by the Borrower without such consent shall be null and void) and
(ii) no Lender may assign or otherwise transfer its rights or obligations
hereunder except in accordance with this Section. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby
(including any Affiliate of the Issuing Bank that issues any Letter of Credit),
Participants (to the extent provided in paragraph (c) of this Section) and, to
the extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b)  (i) Subject to the conditions set forth in paragraph (b)(ii)
     below, any Lender may assign to one or more assignees all or a portion of
     its rights and obligations under this Agreement (including all or a portion
     of its Commitment and the Loans at the time owing to it) with the prior
     written consent (such consent not to be unreasonably withheld) of:

                    (A) the Borrower, provided that no consent of the Borrower
               shall be required for an assignment to a Lender, an Affiliate of
               a Lender, an Approved Fund or, if an Event of Default has
               occurred and is continuing, any other assignee; and

                    (B) the Administrative Agent, provided that no consent of
               the Administrative Agent shall be required for an assignment of
               any Commitment to an assignee that is a Lender with a Commitment
               immediately prior to giving effect to such assignment.

               (ii) Assignments shall be subject to the following additional
          conditions:

                    (A) except in the case of an assignment to a Lender or an
               Affiliate of a Lender or an assignment of the entire remaining
               amount of


                                       57



               the assigning Lender's Commitment or Loans of any Class, the
               amount of the Commitment or Loans of the assigning Lender subject
               to each such assignment (determined as of the date the Assignment
               and Assumption with respect to such assignment is delivered to
               the Administrative Agent) shall not be less than $5,000,000
               unless each of the Borrower and the Administrative Agent
               otherwise consent, provided that no such consent of the Borrower
               shall be required if an Event of Default has occurred and is
               continuing;

                    (B) each partial assignment shall be made as an assignment
               of a proportionate part of all the assigning Lender's rights and
               obligations under this Agreement;

                    (C) the parties to each assignment shall execute and deliver
               to the Administrative Agent an Assignment and Assumption,
               together with a processing and recordation fee of $3,500 (which
               fee shall be paid by the assigning Lender);

                    (D) the assignee, if it shall not be a Lender, shall deliver
               to the Administrative Agent an Administrative Questionnaire in
               which the assignee designates one or more credit contacts to whom
               all syndicate-level information (which may contain material
               non-public information about the Borrower, the Loan Parties and
               their related parties or their respective securities) will be
               made available and who may receive such information in accordance
               with the assignee's compliance procedures and applicable laws,
               including Federal and state securities laws;

                    (E) any Foreign Lender shall have delivered tax certificates
               described in Section 2.16, which indicate that such Foreign
               Lender is exempt from any withholding tax under the law of the
               jurisdiction in which the Borrower is located, or any treaty to
               which such jurisdiction is a party; and

                    (F) the assignee, if it shall not be a Lender, shall deliver
               to the Administrative Agent an Administrative Questionnaire in
               which the assignee designates one or more credit contacts to whom
               all syndicate-level information (which may contain material
               non-public information about the Borrower, the Loan Parties and
               their related parties or their respective securities) will be
               made available and who may receive such information in accordance
               with the assignee's compliance procedures and applicable laws,
               including Federal and state securities laws.

          For the purposes of this Section 9.4(b), the term "Approved Fund" has
     the following meaning:

          "Approved Fund" means any Person (other than a natural person) that is
     engaged in making, purchasing, holding or investing in bank loans and
     similar extensions of credit


                                       58



     in the ordinary course of its business and that is administered or managed
     by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
     Affiliate of an entity that administers or manages a Lender.

               (iii) Subject to acceptance and recording thereof pursuant to
          paragraph (b)(iv) of this Section, from and after the effective date
          specified in each Assignment and Assumption the assignee thereunder
          shall be a party hereto and, to the extent of the interest assigned by
          such Assignment and Assumption, have the rights and obligations of a
          Lender under this Agreement, and the assigning Lender thereunder
          shall, to the extent of the interest assigned by such Assignment and
          Assumption, be released from its obligations under this Agreement
          (and, in the case of an Assignment and Assumption covering all of the
          assigning Lender's rights and obligations under this Agreement, such
          Lender shall cease to be a party hereto but shall continue to be
          entitled to the benefits of Sections 2.14, 2.15, 2.16 and 9.3). Any
          assignment or transfer by a Lender of rights or obligations under this
          Agreement that does not comply with this Section 9.4 shall be treated
          for purposes of this Agreement as a sale by such Lender of a
          participation in such rights and obligations in accordance with
          paragraph (c) of this Section.

               (iv) The Administrative Agent, acting for this purpose as an
          agent of the Borrower, shall maintain at one of its offices a copy of
          each Assignment and Assumption delivered to it and a register for the
          recordation of the names and addresses of the Lenders, and the
          Commitment of, and principal amount of the Loans and LC Disbursements
          owing to, each Lender pursuant to the terms hereof from time to time
          (the "Register"). The entries in the Register shall be conclusive, and
          the Borrower, the Administrative Agent, the Issuing Bank and the
          Lenders may treat each Person whose name is recorded in the Register
          pursuant to the terms hereof as a Lender hereunder for all purposes of
          this Agreement, notwithstanding notice to the contrary. The Register
          shall be available for inspection by the Borrower, the Issuing Bank
          and any Lender, at any reasonable time and from time to time upon
          reasonable prior notice.

               (v) Upon its receipt of a duly completed Assignment and
          Assumption executed by an assigning Lender and an assignee, any
          certificates required by Section 2.16(e), the assignee's completed
          Administrative Questionnaire (unless the assignee shall already be a
          Lender hereunder), the processing and recordation fee referred to in
          paragraph (b) of this Section and any written consent to such
          assignment required by paragraph (b) of this Section, the
          Administrative Agent shall accept such Assignment and Assumption and
          record the information contained therein in the Register; provided
          that if either the assigning Lender or the assignee shall have failed
          to make any payment required to be made by it pursuant to Section
          2.4(c), 2.5(d) or (e), 2.6(b), 2.17(d) or 9.3(c), the Administrative
          Agent shall have no obligation to accept such Assignment and
          Assumption and record the information therein in the Register unless
          and until such payment shall have been made in full, together with all
          accrued interest


                                       59



          thereon. No assignment shall be effective for purposes of this
          Agreement unless it has been recorded in the Register as provided in
          this paragraph.

          (c)  (i) Any Lender may, without the consent of the Borrower, the
     Administrative Agent, the Issuing Bank or the Swingline Lender, sell
     participations to one or more banks or other entities (a "Participant") in
     all or a portion of such Lender's rights and obligations under this
     Agreement (including all or a portion of its Commitment and the Loans owing
     to it); provided that (A) such Lender's obligations under this Agreement
     shall remain unchanged, (B) such Lender shall remain solely responsible to
     the other parties hereto for the performance of such obligations and (C)
     the Borrower, the Administrative Agent, the Issuing Bank and the other
     Lenders shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Agreement.
     Any agreement or instrument pursuant to which a Lender sells such a
     participation shall provide that such Lender shall retain the sole right to
     enforce this Agreement and to approve any amendment, modification or waiver
     of any provision of this Agreement; provided that such agreement or
     instrument may provide that such Lender will not, without the consent of
     the Participant, agree to any amendment, modification or waiver described
     in the first proviso to Section 9.2(b) that affects such Participant.
     Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each
     Participant shall be entitled to the benefits of Sections 2.14, 2.15 and
     2.16 to the same extent as if it were a Lender and had acquired its
     interest by assignment pursuant to paragraph (b) of this Section. To the
     extent permitted by law, each Participant also shall be entitled to the
     benefits of Section 9.8 as though it were a Lender, provided such
     Participant agrees to be subject to Section 2.17(c) as though it were a
     Lender.

               (ii) A Participant shall not be entitled to receive any greater
          payment under Section 2.14 or 2.16 than the applicable Lender would
          have been entitled to receive with respect to the participation sold
          to such Participant. A Participant that would be a Foreign Lender if
          it were a Lender shall not be entitled to the benefits of Section 2.16
          unless the Borrower is notified of the participation sold to such
          Participant and such Participant agrees, for the benefit of the
          Borrower, to comply with Section 2.16(e) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in
     all or any portion of its rights under this Agreement to secure obligations
     of such Lender, including without limitation any pledge or assignment to
     secure obligations to a Federal Reserve Bank, and this Section shall not
     apply to any such pledge or assignment of a security interest; provided
     that no such pledge or assignment of a security interest shall release a
     Lender from any of its obligations hereunder or substitute any such pledgee
     or assignee for such Lender as a party hereto.

          (e) On one or more occasions, one or more Additional Lenders may be
     admitted as Lenders party to this Agreement in connection with an increase
     of the total Commitment pursuant to Section 2.19, subject to (i) execution
     and delivery by any such Additional Lender to the Administrative Agent, for
     recording in the Register, of an Instrument of Adherence substantially in
     the form of Exhibit D hereto (an "Instrument of Adherence"), (ii)
     acceptance of such Instrument of Adherence by each of the


                                       60



     Administrative Agent and the Borrower by their respective executions
     thereof, and (iii) the completion of an Administrative Questionnaire by
     such Additional Lender promptly delivered to the Administrative Agent. Upon
     the satisfaction of the foregoing conditions, from and after the effective
     date specified in each such Instrument of Adherence, the Additional Lender
     shall be a Lender party hereto and have the rights and obligations of a
     Lender hereunder.

     SECTION 9.5. Survival. All covenants, agreements, representations and
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any
Letter of Credit is outstanding and so long as the Commitments have not expired
or terminated. The provisions of Sections 2.14, 2.15, 2.16 and 9.3 and Article
VIII shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof.

     SECTION 9.6. Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof. Except as provided in
Section 4.1, this Agreement shall become effective when it shall have been
executed by the Administrative Agent and when the Administrative Agent shall
have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

     SECTION 9.7. Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

     SECTION 9.8. Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations at any


                                       61



time owing by such Lender or Affiliate to or for the credit or the account of
the Borrower against any of and all the obligations of the Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

     SECTION 9.9. Governing Law; Jurisdiction; Consent to Service of Process.
(a) This Agreement shall be construed in accordance with and governed by the law
of the State of New York.

          (b) The Borrower hereby irrevocably and unconditionally submits, for
     itself and its property, to the nonexclusive jurisdiction of the Supreme
     Court of the State of New York sitting in New York County and of the United
     States District Court of the Southern District of New York, and any
     appellate court from any thereof, in any action or proceeding arising out
     of or relating to this Agreement, or for recognition or enforcement of any
     judgment, and each of the parties hereto hereby irrevocably and
     unconditionally agrees that all claims in respect of any such action or
     proceeding may be heard and determined in such New York State or, to the
     extent permitted by law, in such Federal court. Each of the parties hereto
     agrees that a final judgment in any such action or proceeding shall be
     conclusive and may be enforced in other jurisdictions by suit on the
     judgment or in any other manner provided by law. Nothing in this Agreement
     shall affect any right that the Administrative Agent, the Issuing Bank or
     any Lender may otherwise have to bring any action or proceeding relating to
     this Agreement against the Borrower or its properties in the courts of any
     jurisdiction.

          (c) The Borrower hereby irrevocably and unconditionally waives, to the
     fullest extent it may legally and effectively do so, any objection which it
     may now or hereafter have to the laying of venue of any suit, action or
     proceeding arising out of or relating to this Agreement in any court
     referred to in paragraph (b) of this Section. Each of the parties hereto
     hereby irrevocably waives, to the fullest extent permitted by law, the
     defense of an inconvenient forum to the maintenance of such action or
     proceeding in any such court.

          (d) Each party to this Agreement irrevocably consents to service of
     process in the manner provided for notices in Section 9.1. Nothing in this
     Agreement will affect the right of any party to this Agreement to serve
     process in any other manner permitted by law.

     SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD


                                       62



NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION.

     SECTION 9.11. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

     SECTION 9.12. Confidentiality. (a) Each of the Administrative Agent, the
Issuing Bank and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to the Borrower and its
obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section or (ii) becomes available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis from a source other than the
Borrower. For the purposes of this Section, "Information" means all information
received from the Borrower relating to the Borrower or its business, other than
any such information that is available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis prior to disclosure by the
Borrower. Any Person required to maintain the confidentiality of Information as
provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information. Each of the Administrative Agent, Issuing
Bank, and the Lenders agrees to use reasonable commercial efforts (if it may
legally do so) to provide prior notice of any disclosure of Information pursuant
to clauses (b) or (c) above.

          (b) EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION
     9.12(a) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL
     NON-PUBLIC INFORMATION CONCERNING THE BORROWER AND ITS RELATED PARTIES OR
     THEIR RESPECTIVE SECURITIES, AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE
     PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT
     WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE
     PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.


                                       63



          (c) ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS,
     FURNISHED BY THE BORROWER OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN
     THE COURSE OF ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL
     INFORMATION, WHICH MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE
     BORROWER, THE LOAN PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE
     SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO THE BORROWER AND THE
     ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED IN ITS ADMINISTRATIVE
     QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN
     MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE
     PROCEDURES AND APPLICABLE LAW.

     SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
