(New York City time) on the date of such A Borrowing, make available for the account of its Applicable Lending Office to the Agent at its New York address referred to in Section 8.02, in same day funds, such Bank's ratable portion of such A Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at the Agent's aforesaid address. (b) Anything herein to the contrary notwithstanding: (i) at no time shall there be outstanding to the Borrower more than six A Borrowings comprised of Eurodollar Rate Advances; (ii) the Borrower may not select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less than $20,000,000; (iii) if the Majority Banks shall notify the Agent that either (A) the Eurodollar Rate for any Interest Period for any Eurodollar Rate Advances will not adequately reflect the cost to such Banks of making or funding their respective Eurodollar Rate Advances for such Interest Period, or (B) that U.S. dollar deposits for the relevant amounts and Interest Period for their respective Advances are not available to them in the London interbank market, or it is otherwise impossible to have Eurodollar Rate Advances, the Agent shall forthwith so notify the Borrower and the Banks, whereupon (I) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (II) the obligations of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent, at the request of the Majority Banks, shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and, except as provided in Section 2.02(b)(v), each Advance comprising any requested A Borrowing shall be a Base Rate Advance; (iv) if the Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances, the obligation of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and, except as -13- 18 provided in Section 2.02(b)(v), each Advance comprising any requested A Borrowing shall be a Base Rate Advance; and (v) if the Borrower has requested a proposed A Borrowing consisting of Eurodollar Rate Advances and as a result of circumstances referred to in Section 2.02(b)(iii) or (iv) such A Borrowing would not consist of Eurodollar Rate Advances, the Borrower may, by notice given not later than 3:00 P.M.

(c) Each Notice of A Borrowing shall be irrevocable and binding on the Borrower, except as set forth in Section 2.02(b)(v). In the case of any A Borrowing which the related Notice of A Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Bank against any loss, cost or expense incurred by such Bank as a result of any failure to fulfill on or before the date specified in such Notice of A Borrowing for such A Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of reasonably anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the A Advance to be made by such Bank as part of such A Borrowing when such A Advance, as a result of such failure, is not made on such date. A certificate in reasonable detail as to the basis for and the amount of such loss, cost or expense submitted to the Borrower and the Agent by such Bank shall be prima facie evidence of the amount of such loss, cost or expense. If an A Borrowing which the related Notice of A Borrowing specifies is to be comprised of Eurodollar Rate Advances is not made as an A Borrowing comprised of Eurodollar Rate Advances as a result of Section 2.02(b), the Borrower shall indemnify each Bank against any loss (excluding loss of profits), cost or expense incurred by such Bank by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank prior to the time such Bank is actually aware that such A Borrowing will not be so made to fund the A Advance to be made by such Bank as part of such A Borrowing. A certificate in reasonable detail as to the basis for and the amount of such loss, cost or expense submitted to the Borrower and the Agent by such Bank shall be prima facie evidence of the amount of such loss, cost or expense. (d) Unless the Agent shall have received notice from a Bank prior to the date of any A Borrowing that such Bank will not make available to the Agent such Bank's ratable portion of such A Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such A Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the -14- 19 Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to A Advances comprising such A Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's A Advance as part of such A Borrowing for purposes of this Agreement. (e) The failure of any Bank to make the A Advance to be made by it as part of any A Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its A Advance on the date of such A Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the A Advance to be made by such other Bank on the date of any A Borrowing.

If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Bank or the Agent (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 taxation authority or other authority in accordance with applicable law. (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made by the Borrower hereunder or under the Notes executed by it or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or such Notes (hereinafter referred to as "Other Taxes"). (c) The Borrower will indemnify each Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.14) owed and paid by such Bank or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom -20- 25 or with respect thereto.

(d) Within 30 days after the date of the payment of Taxes by or at the direction of the Borrower, the Borrower will furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof.

The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation.

(iv) If the Borrower notifies the Agent that such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the Agent shall give prompt notice thereof to the Banks and such B Borrowing shall not be made. (v) If the Borrower accepts one or more of the offers made by any Bank or Banks pursuant to paragraph (iii)(B) above, the Agent shall in turn promptly notify (A) each Bank that has made an offer as described in paragraph (ii) above, of the date and aggregate amount of such B Borrowing and whether or not any offer or offers made by such Bank pursuant to paragraph (ii) above have been accepted by the Borrower, (B) each Bank that is to make a B Advance as part of such B Borrowing, of the amount of each B Advance to be made by such Bank as part of such B Borrowing, and (C) each Bank that is to make a B Advance as part of such B Borrowing, upon receipt, that the Agent has received forms of -23- 28 documents appearing to fulfill the applicable conditions set forth in Article III.

(c) Within the limits and on the conditions set forth in this Section 2.16, the Borrower may from time to time borrow under this Section 2.16, repay or prepay pursuant to subsection (d) below, and reborrow under this Section 2.16, provided that a B Borrowing shall not be made by the Borrower within three Business Days of the date of another B Borrowing. (d) The Borrower shall repay to the Agent for the account of each Bank which has made a B Advance to the Borrower, or each other holder of a B Note of the Borrower, on the maturity date of each B Advance made to the Borrower (such maturity date being that specified by the Borrower for repayment of such B Advance in the related Notice of B Borrowing delivered pursuant to subsection (a)(i) above and provided in the B Note evidencing such B Advance) the then unpaid principal amount of such B Advance.

Each Bank agrees promptly to notify the Borrower after such set-off and application made by such Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Bank may have. Section 8.06. Binding Effect; Transfers. (a) This Agreement shall become effective when it shall have been executed by the Borrower and the Agent and when each Bank listed on the signature pages hereof has delivered an executed counterpart hereof to the Agent, has sent to the Agent a facsimile copy of its signature hereon or has notified the Agent that such Bank has executed this Agreement and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each Bank and their respective successors and assigns, except that the Borrower shall not have the right to assign any of its rights hereunder or any interest herein without the prior written consent of all of the Banks. Each Bank may assign to one or more banks, financial institutions or government entities all or any part of, or may grant participations to one or more banks, financial institutions or government entities in or to all or any part of, any Advance or Advances owing to such Bank, any Note or Notes held by such Bank and all or any portion of such Bank's Commitments, and to the extent of any such assignment or participation (unless otherwise stated therein) the assignee or purchaser of such assignment or participation shall, to the fullest extent permitted by law, have the same rights and benefits hereunder and under such Note or Notes as it would have if it were such Bank hereunder, provided that, except in the case of an assignment meeting the requirements of the next sentence hereof, (1) such Bank's obligations under this Agreement, including, without limitation, its Commitment hereunder, shall remain unchanged, such Bank shall remain responsible for the performance thereof, such Bank shall remain the holder of any such Note or Notes for all purposes under this Agreement, and the Borrower, the other Banks and the Agent shall continue to deal solely with and directly with such Bank in connection with such Bank's rights and obligations under this Agreement; and (2) no Bank shall assign or grant a participation that conveys to the assignee or participant the right to vote or consent under this Agreement, other than the right to vote upon or consent to (i) any increase in the amount of any Commitment of such Bank; (ii) any reduction of the principal amount of, or interest to be paid on, such Bank's Advance or Advances or Note or Notes; (iii) any reduction of any fee or other amount payable hereunder to such Bank; or (iv) any postponement of any date fixed for any payment of principal of, or interest on, such Bank's Advance or Advances or Note or Notes or any fee or other amount payable hereunder to such Bank. If (I) the assignee of any Bank either (1) is another Bank or is an affiliate of a Bank or (2) is approved in writing by the Agent and the Borrower or (3) is approved in writing by the Agent and either an Event of Default exists or the Borrower has relinquished the right to approve the assignment pursuant to Section 8.06(b), and (II) such assignee assumes all or any portion (which portion shall be a constant, and not a varying, percentage, and the amount of the Commitment assigned, whether all or a portion, shall be in a minimum amount of $5,000,000 or such lesser amount as may be approved in writing by the Agent and the Borrower for such assignment) of the Commitment of such -46- 51 assigning Bank by executing a document in the form of Exhibit F (or with such changes thereto as have been approved in writing by the Agent in its sole discretion as evidenced by its execution thereof) duly executed by the Agent, the Borrower (unless an Event of Default exists or the Borrower has relinquished the right to approve the assignment pursuant to Section 8.06(b)), such assigning Bank and such assignee and delivered to the Agent ("Transfer Agreement"), then upon such delivery, (i) such assigning Bank shall be released from its obligations under this Agreement with respect to all or such portion, as the case may be, of its Commitments, (ii) such assignee shall become obligated for all or such portion, as the case may be, of such Commitments and all other obligations of such assigning Bank hereunder with respect to or arising as a result of all or such portion, as the case may be, of such Commitments, (iii) such assignee shall be assigned the right to vote or consent under this Agreement, to the extent of all or such portion, as the case may be, of such Commitments, (iv) the Borrower shall deliver, in replacement of the A Note of the Borrower to such assigning Bank then outstanding (a) to such assignee, a new A Note of the Borrower in the amount of the Commitment of such assigning Bank which is being so assumed by such assignee plus, in the case of any assignee which is already a Bank hereunder, the amount of such assignee's Commitment immediately prior to such assignment (any such assignee which is already a Bank hereunder agrees to cancel and return to the Borrower, with reasonable promptness following the delivery of such new A Note, the A Note being replaced thereby), (b) to such assigning Bank, a new A Note in the amount of the balance, if any, of the Commitment of such assigning Bank to the Borrower (without giving effect to any B Reduction) retained by such assigning Bank (and such assigning Bank agrees to cancel and return to the Borrower, with reasonable promptness following delivery of such new A Notes, the A Note being replaced thereby), and (c) to the Agent, photocopies of such new A Notes, (v) if such assignment is of all of such assigning Bank's Commitment, all of the outstanding A Advances made by such assigning Bank shall be transferred to such assignee, (vi) if such assignment is not of all of such Commitments, a part of each A Advance to the Borrower equal to the amount of such Advance multiplied by a fraction, the numerator of which is the amount of such portion of such assigning Bank's Commitment so assumed and the denominator of which is the amount of the Commitment of such assigning Bank (without giving effect to any B Reduction) immediately prior to such assumption, shall be transferred to such assignee and evidenced by such assignee's A Note from the Borrower, and the balance of such A Advance shall be evidenced by such assigning Bank's new A Note from the Borrower delivered pursuant to clause (iv)(b) of this sentence, (vii) if such assignee is not a "Bank" hereunder prior to such assignment, such assignee shall become a party to this Agreement as a Bank and shall be deemed to be a "Bank" hereunder, and the amount of all or such portion, as the case may be, of the Commitment so assumed shall be deemed to be the amount set opposite such assigning Bank's name on Schedule IV for purposes of this Agreement, and (viii) if such assignee is not a Bank hereunder prior to such assignment, such assignee shall be deemed to have specified the offices of such assignee named in the respective Transfer Agreement as its "Domestic Lending Office" and "Eurodollar Lending Office" for all purposes of this Agreement and to have specified for purposes of Section 8.02 the notice information set forth in such Transfer Agreement; and the Agent shall promptly after execution of any Transfer Agreement by the Agent and the other parties thereto notify the Banks of the parties to such Transfer Agreement and the amounts of the assigning Bank's Commitment assumed thereby. -47- 52 (b) If the Borrower does not consent to a proposed assignment by a Bank pursuant to the last sentence of Section 8.06(a), the Borrower may, within 15 days of its receipt of a request that it consent to such assignment nominate by notice to the Agent and such Bank a bank which, if it is not a Bank, is acceptable to the Agent, and which unconditionally offers in writing (with a copy to the Agent) to purchase and assume, to the extent of the amount of such proposed assignment, in accordance with all of the provisions of the last sentence of Section 8.06(a) (including execution of an appropriate Transfer Agreement), all of such Bank's rights and obligations (including, without limitation, its Commitment) hereunder and interest in the Advances owing to such Bank and the Notes held by such Bank without recourse at par plus interest accrued thereon to the date of such purchase on a date therein specified (not less than three nor greater than five Business Days after such nomination). Such Bank at its option may elect to accept or not accept such purchase offer. If a Bank accepts such an offer and the bank first nominated by the Borrower pursuant to this Section 8.06(b) fails to purchase such rights and interest on such specified date in accordance with the terms of such offer, the Borrower may, within 15 days of such failure, repeat the process contemplated by the first sentence of this Section 8.06(b) by nominating another bank for purposes of this Section 8.06(b) by notice to the Agent and such Bank. If the Borrower does not so nominate such a bank within 15 days of its receipt of such request that it consent to such assignment or if the Borrower fails to nominate another bank following such a failure to purchase or if such second nominated bank fails to purchase in accordance with the terms of an offer complying with the first sentence of this Section 8.06(b), the Borrower shall be deemed to have relinquished its right to consent to such assignment. If such Bank elects to not accept such a purchase offer under this Section 8.06(b) as to a particular proposed assignment, the Borrower shall not be deemed to have relinquished its right to consent to such assignment. (c) The Borrower agrees to promptly execute the Transfer Agreement pertaining to any assignment as to which approval by the Borrower of the assignee is not required by clause (I) of the last sentence of Section 8.06(a). (d) Any Bank may assign, as collateral or otherwise, any of its rights (including, without limitation, rights to payments of principal of and/or interest on the Notes) under this Agreement or any of the Notes to any Federal Reserve Bank without notice to or consent of the Borrower or the Agent. Section 8.07. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York. Section 8.08. Interest. It is the intention of the parties hereto that the Agent and each Bank shall conform strictly to usury laws applicable to it, if any. Accordingly, if the transactions with the Agent or any Bank contemplated hereby would be usurious under applicable law, then, in that event, notwithstanding anything to the contrary in the Notes, this Agreement or any other agreement entered into in connection with or as security for this Agreement or the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under applicable law that -48- 53 is contracted for, taken, reserved, charged or received by the Agent or such Bank, as the case may be, under the Notes, this Agreement or under any other agreement entered into in connection with or as security for this Agreement or the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law and any excess shall be cancelled automatically and, if theretofore paid, shall at the option of the Agent or such Bank, as the case may be, be credited by the Agent or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent or such Bank, as the case may be, by the Borrower or refunded by the Agent or such Bank, as the case may be, to the Borrower, and (ii) in the event that the maturity of any Note or other obligation payable to the Agent or such Bank, as the case may be, is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to the Agent or such Bank, as the case may be, may never include more than the maximum amount allowed by such applicable law and excess interest, if any, to the Agent or such Bank, as the case may be, provided for in this Agreement or otherwise shall be cancelled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall, at the option of the Agent or such Bank, as the case may be, be credited by the Agent or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent or such Bank, as the case may be, by the Borrower or refunded by the Agent or such Bank, as the case may be, to the Borrower. Section 8.09. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto 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 8.10. Survival of Agreements, Representations and Warranties, Etc. All warranties, representations and covenants made by the Borrower or any officer of the Borrower herein or in any certificate or other document delivered in connection with this Agreement shall be considered to have been relied upon by the Banks and shall survive the issuance and delivery of the Notes and the making of the Advances regardless of any investigation. The indemnities and other payment obligations of the Borrower contained in this Agreement, and the indemnities by the Banks in favor of the Agent and its officers, directors, employees and agents, will survive the repayment of the Advances and the termination of this Agreement. Section 8.11. Borrower's Right to Apply Deposits. In the event that any Bank is placed in receivership or enters a similar proceeding, the Borrower may, to the full extent permitted by law, make any payment due to such Bank hereunder, to the extent of finally collected unrestricted deposits of the Borrower in U.S. dollars held by such Bank, by giving notice to the Agent and such Bank directing such Bank to apply such deposits to such indebtedness. If the amount of such deposits is insufficient to pay such indebtedness then due and owing in full, the Borrower shall pay the balance of such insufficiency in accordance with this Agreement. Section 8.12. Confidentiality. Each Bank agrees that it will use best efforts, to the extent not inconsistent with practical business requirements, not to disclose without the prior consent -49- 54 of the Borrower (other than to employees, auditors, accountants, counsel or other professional advisors of the Agent or any Bank) any information with respect to the Borrower or its Subsidiaries which is furnished pursuant to this Agreement and which (i) the Borrower in good faith considers to be confidential and (ii) is either clearly marked confidential or is designated by the Borrower to the Agent or the Banks in writing as confidential, provided that any Bank may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or Federal regulatory body having or claiming to have jurisdiction over such Bank or submitted to or required by the Board of Governors of the Federal Reserve System or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (c) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (d) in order to comply with any law, order, regulation or ruling applicable to such Bank, (e) to the prospective transferee in connection with any contemplated transfer of any of the Notes or any interest therein by such Bank, provided that such prospective transferee executes an agreement with or for the benefit of the Borrower containing provisions substantially identical to those contained in this Section 8.12, and provided further that if the contemplated transfer is a grant of a participation in a Note (and not an assignment), no such information shall be authorized to be delivered to such participant pursuant to this clause (e) except (i) such information delivered pursuant to Section 4.01(e) or Section 5.01(b) (other than paragraph (iv) thereof), and (ii) if prior notice of the delivery thereof is given to the Borrower, such information as may be required by law or regulation to be delivered, (f) in connection with the exercise of any remedy by such Bank pertaining to this Agreement, any of the Notes or any other document delivered in connection herewith, (g) in connection with any litigation involving such Bank pertaining to this Agreement, any of the Notes or any other document delivered in connection herewith, (h) to any Bank or the Agent, or (i) to any affiliate of any Bank, provided that such affiliate executes an agreement with or for the benefit of the Borrower containing provisions substantially identical to those contained in this Section 8.12. Section 8.13. WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT, AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY NOTE OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. -50- 55 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.
