(b) Notwithstanding any other provision herein, if after the date of this Agreement any change in applicable law or regulation (either by way of changes in existing laws or regulations or the introductions of new laws or regulations) or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall change the basis of taxation of payments to the Lender of the principal of or interest on any LIBOR Borrowing made by the Lender, Fees or other amounts payable hereunder (other than changes in respect of taxes imposed on the net income of the Lender), or shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by the Lender, including without limitation any reserve requirement that may be applicable to "eurocurrency liabilities" under and as defined in Regulation D, or shall impose on the Lender or the London interbank market any other condition affecting this Agreement or any LIBOR Borrowing made by the Lender, and the result of any of the foregoing shall be to increase the cost to the Lender of making or maintaining any LIBOR Borrowing or to reduce the amount of any sum received or receivable by the Lender hereunder or under the Note (in respect of LIBOR Borrowing only), whether of principal, interest or otherwise, by an amount deemed by the Lender in good faith to be material, then, the Borrower will pay to the Lender upon demand such additional amount or amounts as will compensate the Lender for such additional costs incurred or reduction suffered.

(c) A certificate of the Lender setting forth such amount or amounts as shall be necessary to compensate the Lender or its holding company as specified in paragraph (a) or (b) above, as the case may be, and setting forth in reasonable detail the manner in which such amount or amounts shall have been determined shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay the Lender the amount shown as due on any such certificate delivered by it within ten (10) days after its receipt of the same.

(d) Failure on the part of the Lender to demand compensation for any increased costs or reduction in amounts received or receivable with respect to any period shall not constitute a waiver of the Lender's right to demand compensation with respect to such period or any other period. The protection of this Section shall be available to the Lender regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have occurred or been imposed, provided that if the Lender is compensated for such increased costs or reduction by any Governmental Authority or third party in the event such invalidity or inapplicability is finally determined, then the Lender shall return to the Borrower the respective compensation paid by the Borrower, up to the lesser of such amount as is received by the Lender or such amount as was paid by the Borrower.

(e) Without prejudice to the survival of any other agreement contained herein, the agreements and obligations contained in this Section shall survive Termination, provided that the Borrower shall have no further obligation to the Lender under this Section unless a certificate setting forth the amount of such obligation shall have been delivered by the Lender pursuant to paragraph (c) above within ninety (90) calendar days after the Termination Date.

(f) The Lender shall give notification to the Borrower of any event or prospective event which will give rise to the operation of paragraphs (a) or (b) of this Section, such notification to be sent within thirty (30) days of the date of the public promulgation of the effective date of any such law, rule, regulation, guidelines or change therein.

Section 2.14 Change in Legality.

(a) Notwithstanding any other provision herein, if any change in any law or regulation or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for the Lender to make or maintain any LIBOR Borrowing or to give effect to its obligations as contemplated hereby with respect to any LIBOR Borrowing, then by written notice to the Borrower setting forth in reasonable detail the relevant circumstances and the effect thereof, the Lender may:

(i) declare that LIBOR Borrowings will not thereafter be made by the Lender hereunder, whereupon any request by the Borrower for a LIBOR Borrowing shall be deemed a request for a Base Rate Borrowing unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding LIBOR Borrowings made by it be converted to Base Rate Borrowings, in which event all such LIBOR Borrowings shall be automatically converted to Base Rate Borrowings as of the effective date of such notice as provided in paragraph (b) below.

In the event the Lender shall exercise its rights under (i) or (ii) above, all payments and prepayments of principal which would otherwise have been applied to repay the LIBOR Borrowings that would have been made by the Lender or the converted LIBOR Borrowings of the Lender shall instead be applied to repay the Base Rate Borrowings made by the Lender in lieu of, or resulting from the conversion of, such LIBOR Borrowings.

(b) For purposes of this Section, a notice to the Borrower by the Lender shall be effective as to each LIBOR Borrowing, if lawful, on the last day of the Interest Period currently applicable to such LIBOR Borrowing; in all other cases such notice shall be effective on the date of receipt by the Borrower.

(c) The Lender shall use its best efforts to give prompt notification to the Borrower of any event or prospective event which will give rise to the operation of paragraph (a) of this Section.

Section 2.15 Redeployment Loss. The Borrower shall pay to the Lender on demand against any Redeployment Loss (defined below) arising as a consequence of any payment, prepayment (optional or mandatory) or conversion of a LIBOR Borrowing required by any other provision of this Agreement or otherwise made or deemed made on a date other than the last day of the Interest Period applicable thereto, or failure to borrow, convert or extend a LIBOR Borrowing after giving notice. "Redeployment Loss" shall mean, in each circumstance, a fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in such Interest Period matures, calculated as follows for each such month:

(i) Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until the last day of the Interest Period applicable thereto.

(ii) Subtract from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such Interest Period at the LIBOR Rate in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid.

(iii) If the result obtained in (ii) for any month is greater than zero, discount that difference by the LIBOR Rate used in (ii) above.

The Borrower acknowledges that prepayment of such amount may result in the Lender incurring additional costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. The Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of the prepayment costs, expenses and/or liabilities of the Lender. If the Borrower fails to pay any prepayment fee when due, the amount of such prepayment fee shall thereafter bear interest until paid at the Default Rate.

A certificate of the Lender setting forth in reasonable detail any amount or amounts which the Lender is entitled to receive pursuant to this Section and setting forth in reasonable detail the manner in which such amounts shall have been determined shall be delivered to the Borrower and shall be conclusive absent manifest error. Without prejudice to the survival of any other agreement contained herein, the agreements and obligations contained in this Section shall survive Termination provided that the Borrower shall have no further obligation to the Lender under this Section unless a certificate setting forth the amount of such obligation shall have been delivered by the Lender pursuant to the preceding sentence within ninety (90) calendar days after the Termination Date.

Section 2.16 Payments.

(a) The Borrower shall make each payment (including without limitation principal of or interest on any Borrowing or any Fees or other amounts) hereunder and under any other Loan Document no later than 11:00 a.m., California time, on the date when due in Dollars to the Lender at its offices at 100 West Washington, Phoenix, Arizona, or at such other location as it may direct the Borrower in writing to use, in immediately available funds.

(b) Whenever any payment (including without limitation principal of or interest on any Borrowing or any Fees or other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or Fees, if applicable.

(c) The Borrower authorizes the Lender to collect all principal and interest due under each Loan by charging the Borrower's demand deposit account number 4159-518950 with the Lender, or any other demand deposit account maintained by the Borrower with the Lender, for the full amount thereof. Should there be insufficient funds in any such demand deposit account to pay all such sums when due, the full amount of such deficiency shall be immediately due and payable by the Borrower.

Section 2.17 Taxes.

(a) All payments by the Borrower under this Agreement shall be made without setoff or counterclaim and in such amounts as may be necessary in order that all such payments after deduction or withholding for or on account of any present or future taxes, levies, imposts, duties, withholdings or other charges of whatsoever nature and all liabilities with respect thereto, other than any taxes on or measured by the gross or net income of the Lender pursuant to the income and/or franchise tax laws of the jurisdictions in which the Lender is incorporated or organized or in which the principal office of the Lender or the branch that is a party to this Agreement of the Lender is located (all such nonexcluded taxes, levies, imposts, duties, withholdings and liabilities being hereinafter referred to as "Taxes"), shall not be less than the amounts otherwise specified to be paid by the Borrower to or for the account of the Lender (or any transferee or assignee (each, a "Transferee")) under this Agreement. With respect to each deduction or withholding for or on account of any Taxes of the Lender (or Transferee), the Borrower shall promptly (and in any event not later than forty-five (45) days thereafter) furnish to the Lender (or Transferee) a receipt evidencing payment thereof.

(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 hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as "Stamp Taxes").

(c) The Borrower will indemnify the Lender (or Transferee) for the full amount of Taxes and Stamp Taxes (including without limitation any Taxes or Stamp Taxes imposed by any jurisdiction on amounts payable under this Section) paid by the Lender (or Transferee) and any liability (including without limitation penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Stamp Taxes were correctly or legally asserted by the relevant taxing authority or other Governmental Authority. Such indemnification shall be made within thirty (30) days after the date the Lender (or Transferee) makes written demand therefor. If the Lender, as the result of any Tax with respect to which the Borrower is required to make a payment pursuant to this Section shall realize a tax credit or refund in its country or other jurisdiction of incorporation or organization or in the jurisdiction in which its principal office is then located, which tax credit or refund would not have been realized but for the Borrower's payment of such Tax, the Lender shall pay to the Borrower an amount equal to such tax credit or refund (to the extent of amounts that have been paid by the Borrower under this Section with respect to such credit or refund) net of all out-of-pocket expenses of the Lender; provided that the Borrower, upon the request of the Lender, agrees to return such credit or refund (plus penalties, interest or other charges) to the Lender in the event the Lender is required to repay such credit or refund to the relevant taxing authority. Any amount required to be calculated pursuant to this Section shall be calculated in good faith by the Lender (or Transferee), and such calculation shall be conclusive and binding upon the parties hereto.

(d) Without prejudice to the survival of any other agreement contained herein, the agreements and obligations contained in this Section shall survive Termination, provided that the Borrower shall have no further obligation to the Lender under this Section unless a certificate setting forth the amount of such obligation shall have been delivered by the Lender to the Borrower within ninety (90) calendar days after the Termination Date.

(e) Nothing contained in this Section shall require the Lender to make available any of its tax returns (or any other information relating to its taxes) which it deems to be confidential.

(f) The Lender shall give notification to the Borrower of any event or prospective event which will give rise to the operation of paragraphs (a) or (b) of this Section, such notification to be sent within thirty (30) days of the date of the public promulgation of the effective date of any such Taxes or Stamp Taxes.

Section 2.18 Termination or Assignment of Commitments Under Certain Circumstances.

(a) If the Lender claims any additional amounts payable pursuant to Section 2.13 or Section 2.17 or exercises its rights under Section 2.14, it shall (consistent with legal and regulatory restrictions) (i) promptly notify the Borrower of the circumstances giving rise to such additional amounts or the exercise of such rights and (ii) file any certificate or document requested by the Borrower or take any other action if the making of such a filing or change or the taking of such action would avoid the need for or reduce the amount of any such additional amounts which may thereafter accrue or avoid the circumstances giving rise to such exercise and would not, in the sole determination of the Lender (or Transferee), be otherwise disadvantageous to the Lender (or Transferee).

(b) The Lender represents and warrants to the Borrower that as of the date hereof it is not aware of any claims available to it under Section 2.13, 2.14 or 2.17 or any circumstances which it has determined will enable it to make any such claims.

Section 2.19 Guaranties. At all times prior to Termination, the Borrower shall cause the Loans and the Borrower's obligations under this Agreement to be guaranteed by a valid and effective continuing guaranty (collectively, the "Guaranties") substantially in the form of Exhibit "C", duly executed and delivered by each Subsidiary of the Borrower.

(iii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect; provided that payment by the Lender under such Letter of Credit against presentation of such draft or document shall not have constituted gross negligence or willful misconduct;

Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (i) foreclose against personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

(d) Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators selected according to the Rules; provided, however, that all three arbitrators must actively participate in all hearings and deliberations. Each arbitrator will be a neutral attorney licensed in the State of Arizona or a neutral retired judge of the state or federal judiciary of Arizona, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator's discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of Arizona and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Arizona Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(e) Discovery. In any arbitration proceeding discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than twenty (20) days before the hearing date and within one hundred eighty (180) days of the filing of the dispute with the AAA. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party's presentation and that no alternative means for obtaining information is available.

(f) Class Proceedings and Consolidations. The resolution of any dispute arising pursuant to the terms of this Agreement shall be determined by a separate arbitration proceeding and such dispute shall not be consolidated with other disputes or included in any class proceeding.

(g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding.

(h) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within one hundred eighty (180) days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

(a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of Arizona State court or Federal court of the United States of America sitting in Phoenix, Arizona, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Arizona State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) Each of the parties hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any Arizona State or Federal court sitting in Phoenix, Arizona. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 8.1. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 8.16 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY (AMONG OTHER THINGS) THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 8.17 Confidentiality. The Lender agrees to keep confidential (and to cause its officers, directors, employees, agents and representatives to keep confidential) the Information (as defined below), except that the Lender shall be permitted to disclose Information (i) to such of its officers, directors, employees, agents and representatives (including outside counsel) as need to know such Information; (ii) to the extent required by applicable laws and regulations or by any subpoena or similar legal process, or requested by any bank regulatory authority (provided that the Lender shall, except for Information requested by any such bank regulatory authority, promptly notify the Borrower (to the extent practicable and lawful, notice shall be given to the Borrower before such disclosure is made so as to permit the Borrower to seek a protective order) of the circumstances and content of each such disclosure and shall request confidential treatment of any Information so disclosed); (iii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Agreement, (B) becomes available to the Lender on a non-confidential basis from a source other than the Borrower or its Affiliates, or (C) was available to the Lender on a non-confidential basis prior to its disclosure to the Lender by the Borrower or its Affiliates; or (iv) to the extent the Borrower shall have consented to such disclosure in writing. As used in this Section 8.17, as to the Lender, "Information" shall mean any financial statements, materials, documents and other information that the Borrower or any of its Affiliates may have furnished or may hereafter furnish to the Lender in connection with this Agreement or any other materials prepared by any such person from any of the foregoing.

IN WITNESS WHEREOF, the Borrower and the Lender have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
