from the date of this Agreement up to but not including the Revolving Facility
Commitment Termination Date in an aggregate principal amount not to exceed at
any time outstanding Borrowing Base.

                     (ii)      Each Revolving Facility Loan which shall not
utilize the Revolving Facility Loan Commitment in full shall be in an amount of
not less than Two Hundred Thousand Dollars ($200,000), provided that each LIBOR

made and maintained at such Lender’s Lending Office for such type of Loan. The
failure of any Lender to make any requested Revolving Facility Loan to be made

responsible for the failure of any other Lender to make such Loans to be made by
such other Lender.

364-Day Facility Term Loans may be outstanding, at the Borrowers option, as
either Alternate Base Rate Loans or LIBOR Rate Loans. Each type of Loan shall be
made and maintained at such Lender’s Lending Office for such type of Loan. The
failure of any Lender to make any requested 364-Day Facility Term Loan to be
made by it on the date specified for such Loan shall not relieve any other
Lender of its obligation (if any) to make such Loan on such date, but no Lender
shall be responsible for the failure of any other Lender to make such Loans to
be made by such other Lender.

--------------------------------------------------------------------------------

                     (iv)      Reduction of Commitment. The Borrowers shall have
the right, upon at least ten (10) Business Days’notice to Agent, to terminate in
whole or reduce in part the unused portion of the 364-Day Facility Amount

specifying: (a) the date of such Loan; (b) the amount of such Loan; (c) the type

Facility Term Loans, each Lender will make available to Agent at 1185 Avenue of
the Americas, New York, New York 10036 immediately available funds, such
Lender’s pro rata share of such 364-Day Facility Term Loans. After Agent’s
receipt of such funds, not later than 3:30 P.M. on the date of such 364-Day
Facility Term Loans and upon fulfillment of the applicable conditions set forth
in Article III hereof, Agent will make such 364-Day Facility Term Loans
available to the Borrowers in immediately available funds by crediting the
amount thereof to the Borrowers account with Agent.

          (c)      Letter of Credit Facility.

                     (i)      Letter of Credit Commitment. Subject to the terms
and conditions hereof, Fleet National Bank, in its capacity as issuer of any
Letter of Credit (the “Issuing Lender”) in reliance on the agreements of the
other Lenders set forth in subsection 2.01(c)(iv), agrees to issue letters of
credit (the “Letters of Credit”) for the account of a Borrower on any Business
Day in such form as may be approved from time to time by the Issuing Lender;
provided that the Issuing Lender shall have no obligation to issue any Letter of
Credit if, in the case of any standby letter of credit the proposed beneficiary
thereof is not acceptable to the Issuing Lender or, after giving effect to such
issuance, (A) the Letter of Credit Obligations would exceed the Letter of Credit
Commitment or (B) the availability of Borrowers to borrow pursuant to the
Borrowing Base would be less than zero, or (C) the sum of the Revolving Facility
Loans plus the Letter of Credit Obligations would exceed the Revolving Facility
Commitment.

-14-

--------------------------------------------------------------------------------

                                          Each Letter of Credit shall:     
     

                                          A.      be denominated in Dollars and
shall be either (A) a standby letter of credit issued to support obligations of
the Borrower, contingent or otherwise, under any requirement of law relating to
workmen’s compensation or under any other obligation to the extent such
obligation, and the necessity to provide a Letter of Credit in connection
therewith, arises in the ordinary course of business, or (B) a commercial letter
of credit issued in respect of the purchase of goods by the Borrower and its
Subsidiaries in the ordinary course of business, and

                                          B.      expire (A) in the case of
standby letters of credit, no later than 12 months from the date of issuance or
amendment thereof or (13) in the case of commercial letters of credit, no later
than 120 days from the date of issuance or amendment thereof, but in any event
no later than 30 days prior to the Revolving Facility Termination Date.

                                          C.      be subject to the Uniform
Customs and Practice for Documentary Credits, Pub. 500 and, to the extent not
inconsistent therewith, the laws of the State of New York.

                                          D.      The Issuing Lender shall not
at any time be obligated to issue any Letter of Credit hereunder if such
issuance would conflict with, or cause the Issuing Lender or any Letter of
Credit Participant to exceed any limits imposed by, any applicable requirement
of law.

                     (ii)      Procedure for Issuance of Letters of Credit. Each
Borrower from time to time may request that the Issuing Lender issue a Letter of
Credit by delivering to the Issuing Lender at its address for notices specified
herein an Application therefor, completed to the satisfaction of the Issuing
Lender, and such other certificates, documents and other papers and information
as the Issuing Lender may request. Upon receipt of any Application, the Issuing
Lender will process such Application and the certificates, documents and other
papers and information delivered to it in connection therewith in accordance
with its customary procedures and shall promptly issue the Letter of Credit
requested thereby (but in no event shall the Issuing Lender be required to issue
any Letter of Credit earlier than three Business Days after its receipt of the
Application therefor and all such other certificates, documents and other papers
and information relating thereto) by issuing the original of such Letter of
Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing
Lender and the Borrower. The Issuing Lender shall furnish a copy of such Letter
of Credit to the Borrower promptly following the issuance thereof.

                     (iii)      Fees, Commissions and Other Charges.

                                          A.      Each Borrower shall pay to the
Issuing Lender, for the account of the Issuing Lender, a letter of credit
commission with respect to each Letter >of Credit, computed for the period from
the date of such payment to the date upon which the next such payment is due
hereunder at a rate per annum equal to the Applicable Margin on Revolving
Facility Loans which are LIBOR Loans on such date, calculated on the basis of a
360-day year, of the aggregate amount available to be drawn under such Letter of
Credit on the date on which such fee is calculated; with respect to each Letter
of Credit, a percentage to be agreed upon among the Issuing Lender and the
Lenders of any such letter of credit commission shall be retained by the Issuing
Lender for its own account, and the balance of any letter of credit commission
shall be payable to the Letter of Credit Participants and the Issuing Lender to
be shared ratably among them in accordance with their respective Revolving
Credit Commitment Percentages. Such commissions shall be payable in advance on
the date of issuance of each Letter of Credit and on each Letter of Credit fee
payment date to occur thereafter and shall be nonrefundable.

-15-

--------------------------------------------------------------------------------

                                          B.      In addition to the foregoing
fees and commissions, the Borrower shall pay or reimburse the Issuing Lender for
all normal and customary costs and expenses incurred or charged by the Issuing
Lender in issuing, effecting payment under, amending or otherwise administering
any Letter of Credit.

                                          C.      The Issuing Lender shall,
promptly following its receipt thereof, distribute to the Issuing Lender and the
Letter of Credit Participants all fees and commissions received by the Issuing
Lender for their respective accounts pursuant to this subsection.

                     (iv)      Letter of Credit Participations.

                                          A.      The Issuing Lender irrevocably
agrees to grant and hereby grants to each Letter of Credit Participant and, to
induce the Issuing Lender to issue Letters of Credit hereunder, each Lender
irrevocably agrees to accept and purchase and hereby accepts and purchases from
the Issuing Lender, on the terms and conditions hereinafter stated, for such
Lenders account and risk an undivided interest equal to such Lender’s Revolving
Facility Commitment Percentage in the Issuing Lender’s obligations and rights
under each Letter of Credit issued hereunder and the amount of each draft paid
by the Issuing Lender thereunder. Each Letter of Credit Participant
unconditionally and irrevocably agrees with the Issuing Lender that, if a draft
is paid under any Letter of Credit for which the Issuing Lender is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such Letter of Credit Participant shall pay to the Issuing Lender
upon demand at the Issuing Lender’s address for notices specified herein an
amount equal to such Letter of Credit Participant’s Revolving Facility
Commitment percentage of the amount of such draft, or any part thereof, which is
not so reimbursed.

                                          B.      If any amount required to be
paid by any Letter of Credit Participant to the Issuing Lender in respect of any
unreimbursed portion of any payment made by the Issuing Lender under any Letter
of Credit is not paid to the Issuing Lender within three Business Days after the
date such payment is due, such Letter of Credit Participant shall pay to the
Issuing Lender on demand an amount equal to the product of (i) such amount,
times (ii) the daily average Federal funds rate, as quoted by the Issuing
Lender, during the period from and including the date such payment is required
to the date on which such payment is immediately available to the Issuing
Lender, times (iii) a fraction the numerator of which is the number of days that
elapse during such period and the denominator of which is 360. If any such
amount required to be paid by any Letter of Credit Participant is not in fact
made available to the Issuing Lender by such Letter of Credit Participant within
three Business Days after the date such payment is due, the Issuing Lender shall
be entitled to recover from such Letter of Credit Participant, on demand, such
amount with interest thereon calculated from such due date at the rate per annum
applicable to ABR Loans hereunder. A certificate of the Issuing Lender submitted
to any Letter of Credit Participant with respect to any amounts owing under this
subsection shall be conclusive in the absence of manifest error.

-16-

--------------------------------------------------------------------------------

                                          C.      Whenever, at any time after
the Issuing Lender has made payment under any Letter of Credit and has received
from any Letter of Credit Participant its pro rata share of such payment, the
Issuing Lender receives any payment related to such Letter of Credit (whether
directly from the Borrower or otherwise, including proceeds of collateral
applied thereto by the Issuing Lender), or any payment of interest on account
thereof, the Issuing Lender will distribute to such Letter of Credit Participant
its pro rata share thereof, provided, however, that in the event that any such
payment received by the Issuing Lender shall be required to be returned by the
Issuing Lender, such Letter of Credit Participant shall return to the Issuing
Lender the portion thereof previously distributed by the Issuing Lender to it.

                     (v)      Reimbursement Obligation.

                                          A.      The Borrowers agree to
reimburse the Issuing Lender on each date on which the Issuing Lender notifies
the Borrowers of the date and amount of a draft presented under any Letter of
Credit and paid by the Issuing Lender for the amount of (i) such draft so paid
and (ii) any taxes, fees, charges or other costs or expenses incurred by the
Issuing Lender in connection with such payment. Each such payment shall be made
to the Issuing Lender at its address for notices specified herein in lawful
money of the United States of America and in immediately available funds.

                                          B.      Interest shall be payable on
any and all amounts remaining unpaid by the Borrowers under this subsection from
the date such amounts become payable (whether at stated maturity, by
acceleration or otherwise) until payment in full at the rate which would be
payable on any outstanding ABR Loans which were then overdue.

                                          C.      Each drawing under any Letter
of Credit shall constitute a request by the Borrowers to the Issuing Lender for
a borrowing pursuant to subsection 2.01 of ABR Loans in the amount of such
drawing. The borrowing date with respect to such borrowing shall be the date of
such drawing.

                     (vi)      Obligations Absolute.

                                          A.      Each Borrower’s obligations
under this Section (c) shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Borrower may have or have had against the Issuing Lender or
any beneficiary of a Letter of Credit.

                                          B.      The Borrower also agrees with
the Issuing Lender that the Issuing Lender shall not be responsible for, and the
Borrower’s Reimbursement Obligations shall not be affected by, among other
things, (i) the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, or (ii) any dispute between or among the Borrower and any
beneficiary of any Letter of Credit or any other party to which such Letter of
Credit may be transferred or (iii) any claims whatsoever of the Borrower against
any beneficiary of such Letter of Credit or any such transferee.

-17-

--------------------------------------------------------------------------------

                                          C.      The Issuing Lender shall not
be liable for any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit, except for errors or omissions caused by
the Issuing Lender’s gross negligence or willful misconduct.

                                          D.      Each Borrower agrees that any
action taken or omitted by the Issuing Lender under or in connection with any
Letter of Credit or the related drafts or documents, if done in the absence of
gross negligence or willful misconduct and in accordance with the standards of
care specified in the Uniform Commercial Code of the State of New York, shall be
binding on the Borrower and shall not result in any liability of the Issuing
Lender to the Borrower.

                     (vii)      Letter of Credit Payments. If any draft shall be
presented for payment under any Letter of Credit, the Issuing Lender shall
promptly notify the Borrower of the date and amount thereof. The responsibility
of the Issuing Lender to the Borrower in connection with any draft presented for
payment under any Letter of Credit shall, in addition to any payment obligation
expressly provided for in such Letter of Credit, be limited to determining that
the documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are in conformity with such Letter of Credit.

                     (viii)      Application To the extent that any provision of
any Application related to any Letter of Credit is inconsistent with the
provisions of this Section 2.01(c), the provisions of this Section 2.01(c) shall
apply.

     Section 2.02 Interest. The Borrowers shall pay interest to Agent, for the
account of each Lender, on the outstanding and unpaid principal amount of all
Loans made under this Agreement at a rate per annum as follows:

     (a)      For an Alternate Base Rate Loan at a rate equal to the Alternate
Base Rate plus the Applicable Margin.

     (b)      For a LIBOR Rate Loan at a rate equal to the LIBOR Rate plus the
Applicable Margin.

     Any change in the interest rate based on the Prime Rate or Federal Funds
Rate resulting from a change in the Prime Rate or Federal Funds Rate shall be
effective as of the opening of business on the day on which such change in the
Prime Rate or Federal Funds Rate, respectively, becomes effective.

     Interest on each Alternate Base Rate Loan shall be calculated on the basis
of a year of 365 days for the actual number of days elapsed. Interest on each
LIBOR Rate Loan shall be calculated on the basis of a year of 360 days for the
actual number of days elapsed.

-18-

--------------------------------------------------------------------------------

     Interest on the Loans shall be paid in immediately available funds to Agent
at its Principal Office for the account of the applicable Lending Office of each
Lender as follows:

     (a) For each Alternate Base Rate Loan, on the last day of each quarter
commencing on the last day of the first quarter following such Loan and
continuing on the last day of each successive quarter thereafter.

     (b) For each LIBOR Rate Loan, on the last Business Day of the applicable
Interest Period for such Loan, and on maturity, and, if earlier, upon the
expiration of each three (3) month period following the commencement of such
Interest Period.

               Agent may collect and Borrowers will pay a late charge not to
exceed five (5) percent of any installment of principal or interest, or of any
other amount due to Agent which is not paid or reimbursed by the Borrowers
within ten (10) days of the due date thereof to defray the cost and extra
expense involved in handling such delinquent payment and the increased risk of
non-collection.

               Upon the occurrence and continuance of an Event of Default, or
after maturity, the interest rate for all Loans shall be 2% per annum in excess
of the interest rate in effect at the time of the Event of Default or maturity
(the “Default Rate”); provided, however, said Default Rate shall not apply if
such Event of Default has been waived by Agent, in writing.

               All agreements between the Borrowers, Guarantors and Subsidiaries
and Agent and/or the Lenders are hereby expressly limited so that in no
contingency or event whatsoever, whether by reason of acceleration of maturity
of the indebtedness evidenced hereby or otherwise, shall the amount paid or
agreed to be paid for the use or the forbearance of the indebtedness evidenced
hereby exceed the maximum permissible under applicable law. As used herein, the
term “applicable law” shall mean the law in effect as of the date hereof
provided, however, that in the event there is a change in the law which results
in a higher permissible rate of interest, then said Agreements shall be governed
by such new law as of its effective date. In this regard, it is expressly agreed
that it is the intent of all parties hereto in the execution, delivery and
acceptance of said Agreements to contract in strict compliance with the laws of
the State of New York from time to time in effect. If, under or from any
circumstances whatsoever, fulfillment of any provision hereof or of any of the
Loan Documents at the time of performance of such provision shall be due, shall
involve transcending the limit of such validity prescribed by applicable law,
then the obligation to be fulfilled shall automatically be reduced to limits of
such validity, and if under or from circumstances whatsoever Agent, Lenders or
any of them should ever receive as interest and amount which would exceed the
highest lawful rate, such amount which would be excessive interest shall be
applied to the reduction of the principal balance evidenced hereby and not to
the payment of interest. This provision shall control every other provision of
all agreements between Borrowers, Guarantors, Subsidiaries, Agent and the
Lenders.

     Section 2.03 Conversions and Renewals. So long as an Event of Default has
not occurred and is continuing, the Borrowers may elect from time to time to
convert all or a part of one type of Loan into another type of Loan (i.e., a
LIBOR Rate Loan or an Alternate Base Rate Loan) or to renew all or part of a
Loan by giving Agent notice at one (1) Business Day before conversion into
Alternate Base Rate Loan, and at least two (2) Business Days before the
conversion into or renewal of a LIBOR Rate Loan, specifying: (a) the renewal or
applicable Conversion Date; (b) the amount of the Loan to be converted or
renewed; (c) in the case of conversions, the type of Loan to be converted into;
and (d) in the case of renewals of or a conversion into LIBOR Rate Loans, the
duration of the Interest Period applicable thereto; provided that (i) the
minimum principal amount of each Loan outstanding after a renewal or conversion
shall be Two Hundred Thousand Dollars ($200,000) in the case of Alternate Base
Rate Loans, and Five Hundred Thousand Dollars ($500,000) in the case of LIBOR
Rate Loans; and (ii) LIBOR Rate Loans can be converted only on the last day of
the Interest Period for such Loan. Agent shall promptly notify each Lender of
each such notice. All conversions and renewals shall be made in the proportion
that each Lender’s Loan bears to the total amount of all of the Lenders Loans.
All notices given under this Section 2.03 shall be irrevocable and shall be
given not later than 11:00 A.M. Eastern Time on the day which is not less than
the number of Business Days specified above for such notice. If the Borrowers
shall fail to give Agent the notice as specified above for the renewal or
conversion of a LIBOR Rate Loan prior to the end of the Interest Period with
respect thereto, such LIBOR Rate Loan shall automatically be converted into an
Alternate Base Rate Loan on the last day of the Interest Period for such Loan. A
maximum of twelve (12) LIBOR Rate Loans may be outstanding at any one time.

-19-

--------------------------------------------------------------------------------

     Section 2.04 Commitment and Other Fees. The Borrowers agree to pay to
Agent, for the account of each Lender, a Commitment Fee, computed based upon a
360 day year, on the average daily unused portion of the Lenders’ Commitment
from the date of this Agreement until:

     (a) with respect to Revolving Facility Loans, the Revolving Facility
Commitment Termination Date, payable on the last day of each quarter, commencing
June 30, 2001, and ending on the Revolving Facility Commitment Termination Date;
and

     (b) with respect to 364-Day Facility Term Loans, the 364-Day Facility Term
Loan Commitment Termination Date, payable on the last day of each quarter,
commencing June 30, 2001, and ending on the 364-Day Facility Term Loan
Commitment Termination Date.

     For purposes of this section, the amount of all outstanding Letters of
Credit shall be considered as a part of the used portion of Lenders Commitment.

     Upon receipt of any Commitment Fees, Agent will promptly cause such
payments to be distributed to the Lenders in the proportion that each Lender’s
unused Commitment bears to the total of all the Lenders’ unused Commitments.

     In addition to the above, Borrowers and Agent have entered into a separate
written agreement as to certain additional fees payable to Agent and Lenders.

     Section 2.01 Notes.

     (a) All Revolving Facility Loans made by the Lenders under this Agreement
shall be evidenced by, and repaid with interest in accordance with, separate
promissory notes of the Borrowers in substantially the form of Exhibit D (each,
a “Revolving Facility Note” and collectively, the “Revolving Facility Notes”),
duly completed, dated the date of this Agreement, and payable to each Lender for
the account of their respective Lending Offices, such Revolving Facility Notes
to represent the obligation of the Borrowers to repay the Revolving Facility
Loans. Each Lender is hereby authorized by the Borrowers to endorse on the
schedule attached to the Revolving Facility Note held by it the amount and type
of each Revolving Facility Loan and each renewal, conversion, and payment of
principal amount received by such Lender for the account of its Lending Office
on account of its Revolving Facility Loans, which endorsement shall, in the
absence of manifest error, be conclusive as to the outstanding balance of the
Revolving Facility Loans made by such Lender; provided, however, that the
failure to make such notation with respect to any Revolving Facility Loan or
renewal, conversion, or payment shall not limit or otherwise affect the
obligations of the Borrowers under this Agreement or the Revolving Facility Note
held by such Lender. All Revolving Facility Loans shall be repaid on the
Revolving Facility Commitment Termination Date.

-20-

--------------------------------------------------------------------------------

     (b) All 364-Day Facility Term Loans made by the Lenders under this
Agreement shall be evidenced by, and repaid with interest in accordance with,
separate promissory notes of the Borrowers in substantially the form of Exhibit
E (each, a “364-Day Facility Term Loan Note” and collectively, the “364-Day
Facility Term Loan Notes”), duly completed, dated the date of this Agreement,
and payable to each Lender for the account of their respective Lending Offices,
such 364-Day Facility Term Loan Notes to represent the obligation of the
Borrowers to repay the 364-Day Facility Term Loans. Each Lender is hereby
authorized by the Borrowers to endorse on the schedule attached to the 364-Day
Facility Term Loan Note held by it the amount and type of each 364-Day Facility
Term Loan and each renewal, conversion, and payment of principal amount received
by such Lender for the account of its Lending Office on account of its 364-Day
Facility Term Loans, which endorsement shall, in the absence of manifest error,
be conclusive as to the outstanding balance of the 364-Day Facility Term Loans
made by such Lender; provided, however, that the failure to make such notation
with respect to any 364-Day Facility Term Loan or renewal, conversion, or
payment shall not limit or otherwise affect the obligations of the Borrowers
under this Agreement or the 364-Day Facility Term Loan Note held by such Lender.

     (c) Each 364-Day Facility Term Note shall provide for payment of interest
in accordance with Section 2.02, with the final maturity date being the 364-Day
Facility Commitment Termination Date. While Lenders shall not have any
obligation of any kind whatsoever to Borrowers or any of them to do so, Lenders
may, upon consent of all Lenders as to terms and conditions, offer to convert
the matured 364-Day Term Loans to term loans to be amortized over a period of
time.

     (d) Upon receipt of an affidavit of a duly authorized officer of the Agent
or a Lender, as to the loss, theft, destruction or mutilation of any Note or any
other security document which is not of public record, and, in the case of any
such loss or theft of a Note, furnishing appropriate agreements of
indemnification from the Lender or third parties, the Borrower will issue a
replacement in lieu thereof and otherwise of like tenor.

     Section 2.02 Prepayments. The Borrowers may, upon at least one (1) Business
Day notice to Agent in the case of Alternate Base Rate Loans and at least two
(2) Business Days’ notice to Agent in the case of LIBOR Rate Loans, prepay the
Revolving Facility Notes and/or the 364-Day Facility Term Loan Notes, in whole
or in part, with accrued interest to the date of such prepayment on the amount

this Agreement and under the Notes not later than 12:00 P.M. Eastern Time on the

such Lender’s Loans to which the payment applies bears to the total amount of
all Lenders’ Loans to which the payment applies and (b) other fees payable to
any Lender to be applied in accordance with the terms of this Agreement. The
Borrowers hereby authorizes each Lender, if and to the extent payment is not
made when due under this Agreement or under the Notes, to charge from time to
time against any account of the Borrowers with such Lender any amount as due.
Whenever any payment to be made under this Agreement or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall be
included in the computation of the payment of interest and the applicable

     Section 2.10 Illegality. Notwithstanding any other provision in this
Agreement to the contrary, if any Lender determines that any applicable law,
rule, or regulation, or any change therein, or any change in the interpretation
or administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation or administration thereof, or
compliance by such Lender with any request or directive (whether or not having
the force of law) of any such authority, central bank, or comparable agency
shall make it unlawful or impossible for such Lender (or its Lending Office) to
maintain or fund its LIBOR Rate Loans, then upon notice to the Borrowers (with a
copy to Agent) by such Lender, the outstanding principal amount of all LIBOR
Rate Loans, together with interest accrued thereon, and any other amounts
payable to the Lenders under this Agreement shall be repaid (a) immediately upon
demand of such Lender if such change or compliance with such request, in the
judgment of such Lender, requires immediate repayment, or (b) at the expiration
of the last Interest Period to expire before the effective date of any such
change or request.

     Section 2.3 Disaster. Notwithstanding anything to the contrary herein, if
Agent determines (which determination shall be conclusive) that:

          (a)      Quotations of interest rates for the relevant deposits
referred to in the definition of LIBOR Interest Rate, as the case may be, are
not being provided in the relevant amounts or for the relative maturities for
purposes of determining the rate of interest on a LIBOR Rate Loan as provided in
this Agreement; or

          (b)      If the Required Lenders determine (which determination shall
be conclusive) that the relevant rates of interest referred to in the definition
of LIBOR Interest Rate, upon the basis of which the rate of interest for any
such type of Loan is to be determined do not accurately cover the cost to the
Lenders of making or maintaining such type of Loans; then Agent shall forthwith
give notice thereof to the Borrowers, whereupon (i) the obligation of the
Lenders to make LIBOR Rate Loans, shall be suspended until Agent notifies the
Borrowers that the circumstances giving rise to such suspension no longer exist,
and (ii) the Borrowers shall repay in full the then outstanding principal amount
of each LIBOR Rate Loan, as the case may be, together with accrued interest
thereon, on the last day of the then current Interest Period applicable to such
Loan or convert from LIBOR to Alternate Base Rate Loans pursuant to Section
2.03.

     Section 2.4 Increased Cost. From time to time upon notice to the Borrowers
from a Lender (with a copy to Agent), the Borrowers shall pay to Agent, for the
account of the applicable Lender, such amounts as any Lender may determine to be
necessary to compensate such Lender for any costs incurred by such Lender which
such Lender determines are attributable to its making or maintaining any LIBOR
Rate Loans hereunder or its obligation to make any such Loans hereunder, or any
reduction in any amount receivable by such Lender under this Agreement or its
Note in respect of any such Loans or such obligation (such increases in costs
and reductions in amounts receivable being herein called “Additional Costs”),
resulting from any change after the date of this Agreement in U.S. federal,
state, municipal, or foreign laws or regulations (including Regulation D), or
the adoption or making after such date of any interpretations, directives, or
requirements applying to a class of banks including such Lender of or under U.S.
federal, state, municipal, or foreign laws or regulations (whether or not having
the force of law) by any court or governmental or monetary authority charged
with the interpretation or administration thereof (“Regulatory Change”), which:
(a ) changes the basis of taxation of any amounts payable to such Lender under
this Agreement or its Note in respect of any of such Loans (other than taxes
imposed on the overall net income of such Lender or of its Lending Office for
any of such Loans by the jurisdiction where the Principal Office or such Lending
Office is located); or (b) imposes or modifies any reserve, special deposit,
compulsory loan, or similar requirements relating to any extensions of credit or
other assets of, or any deposits with or other liabilities of, such Lender
(including any of such Loans or any deposits referred to in the definition of
LIBOR Interest Rate); or (c) imposes any other condition affecting this
Agreement or such Lenders Note (or any of such extensions of credit or
liabilities). Such Lender will notify the Borrowers (with a copy to Agent) of
any event occurring after the date of this Agreement which will entitle such
Lender to compensation pursuant to this Section 2.12 as promptly as practicable
after it obtains knowledge thereof and determines to request such compensation.

-23-

--------------------------------------------------------------------------------

     Determinations by any Lender for purposes of this Section 2.12 of the
effect of any Regulatory Change on its costs of making or maintaining Loans or
on amounts receivable by it in respect of Loans, and of the additional amounts
required to compensate such Lender in respect of any Additional Costs, shall be
conclusive, provided that such determinations are made on a reasonable basis.

     Section 2.13 Risk-Based Capital. In the event that any Lender determines
that (a) compliance with any judicial, administrative, or other governmental
interpretation of any law or regulation or (b) compliance by such Lender or any
corporation controlling such Lender with any guideline or request from any
central bank or other governmental authority (whether or not having the force of
law) has the effect of requiring an increase in the amount of capital required
or expected to be maintained by such Lender or any corporation controlling such
Lender, and such Lender determines that such increase is based upon its
obligations hereunder, and other similar obligations, the Borrowers shall pay to
Agent, for the account of such Lender, such additional amount as shall be
certified by such Lender to be the amount allocable to such Lenders obligations
to the Borrowers hereunder. Such Lender will notify the Borrowers (with a copy
to Agent) of any event occurring after the date of this Agreement that will
entitle such Lender to compensation pursuant to this Section 2.13 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation.

     Determinations by any Lender for purposes of this Section 2.13 of the
effect of any increase in the amount of capital required to be maintained by
such Lender and of the amount allocable to such Lender’s obligations to the
Borrowers hereunder shall be conclusive, provided that such determinations are
made on a reasonable basis.

     Section 2.14 Funding Loss Indemnification. Upon notice to the Borrowers
from a Lender (with a copy to Agent), the Borrowers shall pay to Agent, for the
account of the applicable Lender, such amount or amounts as shall be sufficient
(in the reasonable opinion of such Lender) to compensate it for any loss, cost,
or expense incurred as a result of:

-24-

--------------------------------------------------------------------------------

(a) Any payment of a LIBOR Rate Loan on a date other than the last day of the
Interest Period for such Loan including, but not limited to acceleration of the
Loans by Agent but excluding any such payment made as a mandatory prepayment
pursuant to Section 2.06 hereof in connection with a voluntary sale of assets,
or debt offering or equity offering; or

(b) Any failure by the Borrowers to borrow or convert, as the case may be, a
LIBOR Rate Loan on the date for borrowing or conversion, as the case may be.

     Section 2.15 Guaranties. Within thirty (30) business days after its
organization, payment and performance of the Loans will be unconditionally
guaranteed by each Subsidiary, present and future, of each Borrower by execution
of a Guaranty. Further, within thirty (30) Business Days after its organization,
each Subsidiary shall (a) become a Borrower under the Agreement, and shall be
bound by the Agreement as fully as if it were an original signatory thereto, and
(b) provide Agent with such documentation as may be required to effectuate the
foregoing.

     Section 2.16 Security. Payment and performance of the Revolving Facility
Loans and the 364-Day Facility Term Loans shall be secured by a first priority
security interest in the Collateral.

     Section 2.17 Non-Receipt of Funds by Agent. Unless Agent shall have
received notice from a Lender, prior to the date on which such Lender is to
provide funds to Agent for a Loan to be made by such Lender, that such Lender
will not make available to Agent such funds, Agent may assume that such Lender
has made such funds available to Agent on the date of such Loan in accordance
with Section 2.01 and Agent, in its sole discretion, may, but shall not be
obligated to, in reliance upon such assumption, make available to a Borrower on
such date a corresponding amount. If and to the extent such Lender shall not
have so made such funds available to Agent, such Lender agrees to repay to Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to a Borrower until the
date such amount is repaid to Agent, at the customary rate set by Agent for the
correction of errors among banks for three (3) Business Days and thereafter at
the Prime Rate. If such Lender shall repay such corresponding amount to Agent,
such amount so repaid shall constitute that Lender’s Loan for purposes of this
Agreement. If such Lender does not pay such corresponding amount forthwith upon
Agent’s demand therefor, Agent shall promptly notify such Borrower, and such
Borrower shall immediately pay such corresponding amount to Agent with interest
thereon, for each day from the date such amount is made available to such
Borrower until the date such amount is repaid to Agent, at the rate of interest
applicable at the time to such proposed Loan.

     Unless Agent shall have received notice from the Borrowers prior to the
date on which any payment is due to the Lenders hereunder that the Borrowers
will not make such payment in full, Agent may assume that the Borrowers have
made such payment in full to Agent on such date and Agent in its sole discretion
may, but shall not be obligated to, in reliance upon such assumption, cause to
be distributed to each Lender on such due date an amount equal to the amount
then due such Lender. If and to the extent the Borrowers shall not have so made
such payment in full to Agent, each Lender shall repay to Agent forthwith on
demand such amount distributed to such Lender together with interest thereon,
for each day from the date such amount is distributed to such Lender until the
date such Lender repays such amount to Agent, at the customary rate set by Agent
for the correction of errors among banks for three (3) Business Days and
thereafter at the Prime Rate.

-25-

--------------------------------------------------------------------------------

     Section 2.18 Application of Payments. So long as an Event of Default has
occurred and is continuing, all payments shall be applied as follows:

          (a)      Against fees or commissions due;

          (b)      Against accrued interest;

          (c)      Against principal to be applied to such obligations and in
such order as the Required Lenders shall determine, provided however that, if

installment, then such prepayments shall be applied in inverse order of maturity
of such installments.

-43-

--------------------------------------------------------------------------------

     With respect to all Letters of Credit with respect to which presentment for
honor shall not have occurred at the time of an acceleration pursuant to the
preceding paragraph, the Borrower shall at such time deposit in a cash
collateral account opened by the Agent an amount equal to the aggregate then
undrawn and unexpired amount of such Letters of Credit. The Borrower hereby
grants to the Agent, for the benefit of the Issuing Lender and the Letter of
Credit Participants, a security interest in such cash collateral to secure all
obligations of the Borrower under this Agreement and the other Loan Documents.
Amounts held in such cash collateral account shall be applied by the Agent to
the payment of drafts drawn under such Letters of Credit, and the unused portion
thereof after all such Letters of Credit shall have expired or been fully drawn
upon, if any, shall be applied to repay other obligations of the Borrower
hereunder and under the Notes. After all such Letters of Credit shall have
expired or been fully drawn upon, all reimbursement obligations shall have been
satisfied and all other Obligations of the Borrower hereunder and under the
Notes shall have been paid in full, the balance, if any, in such cash collateral
account shall be returned to the Borrower. The Borrower shall execute and
deliver to the Agent, for the account of the Issuing Lender and the Letter of
Credit Participants, such further documents and instruments as the Agent may
request to evidence the creation and perfection of the within security interest
in such cash collateral account.

     Without limiting the foregoing, upon the occurrence of any Event of
Default, Agent may, and, upon the request of the Required Lenders, shall, at any
time and from time to time, take any and all such action as Agent may elect to
enforce any and all rights and interest created and existing under the Loan
Documents or arising under applicable law, including, without limitation, all
rights and remedies existing under the Security Agreements (the enumeration of
any such rights not intended to be exhaustive and the exercise of any right
shall not preclude the exercise of any other rights).

     Further, upon the occurrence and during the continuance of any Event of
Default, each Lender is hereby authorized at any time and from time to time,
without notice to any Borrower (any such notice being expressly waived by each
Borrower), to set off and apply any and all deposits (general or special, time
or demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of a Borrower
against any and all of the obligations of such Borrower now or hereafter
existing under this Agreement or such Lender’s Note or any other Loan Document,
irrespective of whether or not Agent or such Lender shall have made any demand
under this Agreement or such Lender’s Note or such other Loan Document and
although such obligations may be unmatured. Each Lender agrees promptly to
notify the Borrowers (with a copy to Agent) after any such setoff and
application, provided that the failure to give such notice shall not affect the
validity of such setoff and application. The rights of each Lender under this
Section 8.01 are in addition to other rights and remedies (including, without
limitation, other rights of setoff) which such Lender may have.

ARTICLE IX.

AGENCY PROVISIONS

     Section 9.01 Authorization and Action. Each Lender hereby irrevocably
appoints and authorizes Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement as are delegated to Agent by the terms
hereof, together with such powers as are reasonably incidental thereto. The
duties of Agent shall be mechanical and administrative in nature and Agent shall
not by reason of this Agreement be a trustee or fiduciary for any Lender. Agent
shall have no duties or responsibilities except those expressly set forth
herein. Agent shall furnish the Lenders with copies of any financial reports
received by Agent pursuant to paragraphs 5.08(a), 5.08(b), 5.08(e), 5.08(f) and
5.08(g), promptly after receipt thereof by Agent. As to any matters not
expressly provided for by this Agreement (including, without limitation,
enforcement or collection of the Notes), Agent shall not be required to exercise
any discretion or take any action, but shall be required to act or to refrain
from acting (and shall be fully protected in so acting or so refraining from
acting) upon the instructions of the Required Lenders, and such instructions
shall be binding upon all Lenders and all holders of Notes; provided, however,
that Agent shall not be required to take any action which exposes Agent to
personal liability or which is contrary to this Agreement or applicable law.

     Section 9.02 Liability of Agent. Neither Agent nor any of its directors,
officers, agents or employees shall be liable for any action taken or omitted to
be taken by it or them under or in connection with this Agreement in the absence
of its or their own gross negligence or willful misconduct. Without limitation
of the generality of the foregoing, Agent (a) may treat the payee of any Note as
the holder thereof until Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to Agent; (b) may

public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants, or experts; (c) makes no warranty or
representation to the Lenders and shall not be responsible to the Lenders for
any statements, warranties, or representations made in or in connection with
this Agreement; (d) shall not have any duty to ascertain or to inquire as to the

Agreement on the part of the Borrowers, or to inspect the property (including
the books and records) of the Borrowers; (e) shall not be responsible to the
Lenders for the due execution, legality, validity, enforceability, genuineness,
perfection, sufficiency, or value of this Agreement or any other instrument or
document furnished pursuant thereto; and (f) shall incur no liability under or
in respect of this Agreement by acting upon any notice, consent, certificate, or
other instrument or writing (which may be sent by telegram, telex, or facsimile
transmission) believed by it to be genuine and signed or sent by the proper
party or parties.

-45-

--------------------------------------------------------------------------------

     Agent shall be fully justified in failing or refusing to take any action
under this Agreement or any other Loan Document unless it shall first receive
such advice or concurrence of the Required Lenders as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. In all cases the Agent shall be fully
protected in acting, or in refraining from acting, under this Agreement and the
Notes and the other Loan Documents in accordance with a request of the Required
Lenders, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders and all future holders of the
Notes.

     Section 9.03 Rights of Agent as a Lender. With respect to its Commitment,
the Loans made by it and the Note issued to it, Agent shall have the same rights
and powers under this Agreement as any other Lender and may exercise the same as
though it were not Agent; and the term “Lender” or “Lenders” shall, unless
otherwise expressly indicated, include Agent in its individual capacity. Agent
and its Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, the Borrowers,
any of its Subsidiaries and any Person who may do business with or own
securities of the Borrowers or any Subsidiary, all as if Agent were not Agent
and without any duty to account therefor to the Lenders.

     Section 9.04 Independent Credit Decisions. Each Lender acknowledges that it
has, independently and without reliance upon 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 Agent or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement. Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
Agent hereunder, Agent shall have no duty or responsibility to provide the
Lender with any credit or other information concerning the affairs, financial
condition or business of the Borrowers or any of them, any Guarantor or any
Subsidiary (or any of their respective Affiliates) which may come into the
possession of Agent or any of its Affiliates.

-46-

--------------------------------------------------------------------------------

     Section 9.05 Indemnification. The Lenders to indemnify Agent (to the extent
not reimbursed by the Borrowers), ratably according to the respective amounts of
their Commitment, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against Agent in any way relating to or arising out of this Agreement
or any action taken or omitted by Agent under this Agreement, provided that
Agent shall be liable for any portion of any of the foregoing resulting from
Agent’s gross negligence or willful misconduct. Without limitation of the
foregoing, the Lenders agree to reimburse Agent (to the extent not reimbursed by
the Borrowers) promptly upon demand for its ratable share of any out-of-pocket
expenses (including reasonable counsel fees) incurred by Agent in connection
with the preparation, administration, or enforcement of, or legal advice in
respect of rights or responsibilities under, this Agreement.

     Section 9.06 Notice of Default. Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default unless the Agent
has received notice from a Lender or a Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
“notice of default.” In the event that the Agent receives such a notice, the
Agent shall give prompt notice thereof to the Lenders. The Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders; provided that unless and until the Agent shall
have received such directions, the Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interests of
the Lenders.

     Section 9.07 Successor Agent. Agent may resign at any time by giving at
least sixty (60) days’ prior written notice thereof to the Lenders and the
Borrowers and may be removed at any time with or without cause by the Required
Lenders. Upon any such resignation or removal, the Required Lenders shall have
the right to appoint a successor Agent. If no successor Agent shall have been so
appointed by the Required Lenders, and shall have accepted such appointment,
within thirty (30) days after the retiring Agent’s giving of notice of
resignation or the Required Lenders’ removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which
shall be a commercial bank organized under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least One Billion Dollars ($1,000,000,000). Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations under this Agreement. After any retiring Agent’s
resignation or removal hereunder as Agent, the provisions of this Article IX
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement.

     Section 9.08 Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
setoff, or otherwise) on account of the Note held by it in excess of its ratable
share of payments on account of the Notes obtained by all the Lenders, such
Lender shall purchase from the other Lenders such participations in the Notes
held by them as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of the other Lenders, provided, however, that
if all or any portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each Lender shall be rescinded and each
Lender shall repay to the purchasing Lender the purchase price to the extent of
such recovery together with an amount equal to such Lender’s ratable share
(according to the proportion of (a) the amount of such Lender’s required
repayment to (b) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 9.08
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of setoff) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

-47-

--------------------------------------------------------------------------------

     Section 9.09 Successors and Assigns, Participations and Assignments

     (a) This Agreement shall be binding upon and inure to the benefit of each
Borrower, the Lenders, the Agent and their respective successors and assigns,
except that each Borrower may not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

     (b) Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other entities (“Participants”) participating interests in any Loan
owing to such Lender, any Commitment of such Lender or any other interest of
such Lender hereunder and under the other Loan Documents. In the event of any
such sale by a Lender of a participating interest to a Participant, such
Lender’s obligations under this Agreement to the other parties to this Agreement
shall remain unchanged, such Lender shall remain solely responsible for the
performance thereof, such Lender shall remain the holder of any such Loan for
all purposes under this Agreement and the other Loan Documents, and each
Borrower and the Agent shall continue to deal solely and directly with such
Lender in connection with such Lender’s rights and obligations under this
Agreement and the other Loan Documents. Each Borrower agrees that if amounts
outstanding under this Agreement are due or unpaid, or shall have been declared
or shall have become due and payable upon the occurrence of an Event of Default,
each Participant shall, to the maximum extent permitted by applicable law, be
deemed to have the right of setoff in respect of its participating interest in
amounts owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, provided that, in purchasing such participating interest, such
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in subsection 9.08 as fully as if it were a Lender
hereunder. Each Participant shall be entitled to the benefits of subsections
2.10, 2.11, 2.12 and 2.13 with respect to its participation in the Commitments
and the Loans outstanding from time to time as if it was a Lender; so long as
such Participant shall have complied with the requirements of this subsection
provided that no Participant shall be entitled to receive any greater amount
pursuant to any such subsection than the transferor Lender would have been
entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

     (c) Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time and from time to
time assign to any Lender or any affiliate thereof or, with the consent of
IMPATH Inc. (which consent shall not be required if an Event of Default has
occurred and is continuing) and the Agent (which consents shall not be
unreasonably withheld), to an additional bank or financial institution (so long
as such assignee is either a domestic U.S. bank or a U.S. branch of a foreign
bank and has unrestricted capital of at least Five Hundred Million Dollars
($500,000,000) (an “Assignee”) all or any part of its rights and obligations
under this Agreement and the other Loan Documents pursuant to an Assignment and
Acceptance, substantially in the form of Exhibit H hereto, executed by such
Assignee, such assigning Leader (and, in the case of an Assignee that is not
then a Lender or an affiliate thereof, by the Agent) and delivered to the Agent
for its acceptance and recording in the Register (as defined herein), provided
that, in the case of any such assignment to an additional bank or financial
institution (unless such assignment is made at a time when an Event of Default
shall have occurred and be continuing, for a period in excess of 60 days), (i)
the sum of the aggregate principal amount of the Loans, the aggregate amount of
the Letter of Credit Obligations and the aggregate amount of the Revolving
Credit Commitments being assigned and (ii) if such assignment is of less than
all of the rights and obligations of the assigning Lender, the sum of the
aggregate principal amount of the Loans, the aggregate amount of the Letter of
Credit Obligations and the aggregate amount of the Revolving Credit Commitments
remaining with the assigning Lender, are each not less than Five Million Dollars
($5,000,000) (or such lesser amount as may be agreed to by each Borrower and the
Agent). Upon such execution, delivery, acceptance and recording, from and after
the effective date determined pursuant to such Assignment and Acceptance, (x)
the Assignee thereunder shall be a party hereto and, to the extent provided in
such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with a Commitment as set forth therein, and (y) the assigning Lender
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Leader’s rights and obligations under this Agreement, such assigning Lender
shall cease to be a party hereto).

-48-

--------------------------------------------------------------------------------

     (d) The Agent, on behalf of each Borrower, shall maintain at the address of
the Agent referred to in subsection 10.02 a copy of each Assignment and
Acceptance delivered to it and a register (the “Register”) for the recordation
of the names and addresses of the Lenders and the Commitments of, and principal
amounts of the Loans owing to, each Lender from time to time. The entries in the
Register shall be conclusive, in the absence of manifest error, and each
Borrower, the Agent and the Leaders may (and, in the case of any Loan or other
obligation hereunder not evidenced by a Note, shall) treat each Person whose
name is recorded in the Register as the owner of a Loan or other obligation
hereunder as the owner thereof for all purposes of this Agreement and the other
Loan Documents, notwithstanding any notice to the contrary. Any assignment of
any Loan or other obligation hereunder not evidenced by a Note shall be
effective only upon appropriate entries with respect thereto being made in the
Register. The Register shall be available for inspection by each Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

     (e) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an Assignee (and, in the case of an Assignee that is not
then a Lender or an affiliate thereof, by the Agent) together with payment to
the Agent of a registration and processing fee of $3,500 from the Assignor or
the Assignee, the Agent shall (i) promptly accept such Assignment and Acceptance
and (ii) on the effective date determined pursuant thereto record the
information contained therein in the Register and give notice of such acceptance
and recordation to the Lenders and each Borrower.

     (f) Each Borrower authorizes each Lender to disclose to any Participant or
Assignee (each, a “Transferee”) and any prospective Transferee any and all
financial information in such Lender’s possession concerning each Borrower and
its Affiliates which has been delivered to such Lender by or on behalf of each
Borrower pursuant to this Agreement or which has been delivered to such Lender
by or on behalf of each Borrower in connection with such Lender’s credit
evaluation of the Borrower and its Affiliates prior to becoming a party to this
Agreement.

-49-

--------------------------------------------------------------------------------

     (g) For avoidance of doubt, the parties to this Agreement acknowledge that
the provisions of this subsection concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank
in accordance with applicable law.

counterparts and by different parties to this Agreement in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same Agreement.

     Section 10.11 Headings. Article and Section headings in the Loan Documents
are included in such Loan Documents for the convenience of reference only and
shall not constitute a part of the applicable Loan Documents for any other
purpose.

     Section 10.12 Jury Trial Waiver; Jurisdiction, Etc. EACH BORROWER AND EACH
GUARANTOR AND SUBSIDIARY HEREBY WAIVE TRIAL BY JURY IN ANY ACTION/ PROCEEDING,
CLAIM OR COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, ARISING
OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT OR THE LOAN DOCUMENTS. NO OFFICER
OF ANY OF THE LENDERS HAS AUTHORITY TO WAIVE, CONDITION, OR MODIFY THIS
PROVISION. EACH BORROWER HEREBY FURTHER AGREES THAT THE FOLLOWING COURTS:

     State Court - Any state or local court of the State of New York;

     Federal Court - United States District Court for the Southern District of
New York;

or at the option of Agent, any court in which Agent shall initiate legal or
equitable proceedings and which has subject matter jurisdiction over the matter
in controversy, shall have exclusive jurisdiction to hear and determine any
claims or disputes between any Borrower and Agent pertaining directly or
indirectly to this Agreement or to any matter arising in connection with this
Agreement. Each Borrower expressly submits and consents in advance to such
jurisdiction in any action or proceeding commenced in such courts, hereby
waiving personal service of the summons and complaint, or other process of
papers issued therein, and agreeing that service of such summons and complaint,
or other process or papers, may be made by registered or certified mail
addressed to the Borrowers at the address set forth herein. Should any Borrower
fail to appear or answer any summons, complaint, process or papers so served
within thirty (30) days after the mailing thereof, it shall be deemed in default
and an order and/or judgment may be entered against it as demanded or prayed for
in such summons, complaint, process or papers. The exclusive choice of forum set
forth herein shall not be deemed to preclude the enforcement of any judgment
obtained in such forum or the taking of any action under this Agreement to
enforce the same in any appropriate jurisdiction. Agent may have rights against
any or all of the Borrowers, now or in the future, in its capacity as secured
party, creditor, or in any other capacities. Such rights may include the right
to deprive any such Borrower of or affect the use of or possession or enjoyment
of such Borrower’s property; and in the event Agent deems it necessary to
exercise any of such rights prior to the rendition of a final judgment against
any such Borrower, or otherwise, such Borrower may be entitled to notice and/or
hearing under the Constitution of the United States and/or State of New York,
New York statutes (to determine whether or not Agent has a probable cause to
sustain the validity of Agent’s claim), or the right to notice and/or hearing
under other applicable state or federal laws pertaining to prejudgment remedies
prior to the exercise by Agent of any such rights. Each Borrower expressly
waives any such right to prejudgment remedy notice or hearing to which such
Borrower may be entitled; provided, however, that this waiver shall not include
a waiver of such rights as such Borrower shall have to prior notice of the
proposed disposition of Collateral by Agent. Specifically and without limiting
the generality of the foregoing, each Borrower recognizes that in certain
instances Agent has and shall continue to have an absolute right to effect
collection of any of the Receivables or Collateral with respect to which Agent
holds a security interest without the necessity of according to each Borrower
any prior notice or hearing. This shall be a continuing waiver and remain in
full force and effect so long as any Borrower is obligated to Agent.
