ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission, or SEC, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended. We may offer the securities described in this prospectus from time to time in one or more offerings. This prospectus only provides you with a general description of the securities to be offered. Each time we sell securities pursuant to this prospectus, we will describe in a prospectus supplement, which will be delivered with this prospectus, specific information about the offering and the terms of the particular securities to be offered. The applicable prospectus supplement may also add, update or change the information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any applicable prospectus supplement, you should rely on the information in the applicable prospectus supplement. You should carefully read both this prospectus and any applicable prospectus supplement, together with the additional information described under the heading “Where You Can Find More Information.”

The registration statement of which this prospectus is a part, including the exhibits to the registration statement, provides additional information about us and the securities. Wherever references are made in this prospectus to information that will be included in a prospectus supplement, to the extent permitted by applicable law, rules or regulations, we may instead include such information or add, update or change the information contained in this prospectus by means of a post-effective amendment to the registration statement of which this prospectus is a part, through filings we make with the SEC that are incorporated by reference into this prospectus or by any other method as may then be permitted under applicable law, rules or regulations. The registration statement, including the exhibits to the registration statement and any post-effective amendment thereto, can be obtained from the SEC, as described under the heading “Where You Can Find More Information.”

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This prospectus (including the information incorporated by reference in this prospectus) contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that address activities, events or developments that we or our management intends, expects, projects, believes or anticipates will or may occur in the future. All statements regarding future performance, earnings projections, earnings guidance, management’s expectations about its future cash needs and effective tax rate, and other future events or developments are forward-looking statements. Forward-looking statements use such words as “may,” “will,” “expect,” “believe,” “intend,” “should,” “could,” “anticipate,” “estimate,” “forecast,” “project,” “plan,” “predict,” “potential” and similar expressions. They are based on management’s assumptions and assessments in the light of past experience and trends, current conditions, expected future developments and other relevant factors. They are not guarantees of future performance, and actual results, developments and business decisions may differ from those envisaged by our forward-looking statements, and we do not assume any obligation to update them. Our forward-looking statements are also subject to risks and uncertainties, which can affect our performance in both the near- and long-term. These forward-looking statements should be considered in light of the information included in this prospectus, including the information under the heading “Risk Factors” in our annual report on Form 10-K for the year ended July 31, 2009, and the other reports that we file with the SEC.

Risks and uncertainties that could materially affect future results include:

•     the effect of litigation and regulatory inquiries associated with the restatement of our prior period financial statements;

•     our ability to successfully complete our business improvement initiatives, which include integrating and upgrading our information systems, and the effect of a serious disruption in our information systems;

•     the impact of legislative, regulatory and political developments globally and the impact of the uncertain global economic environment and the timing and strength of a recovery in the markets and regions we serve, and the extent to which adverse economic conditions may affect our sales volume and results;

•     demand for our products and business relationships with key customers and suppliers, which may be impacted by their cash flow and payment practices, as well as delays or cancellations in shipments;

•     volatility in foreign currency exchange rates, interest rates and energy costs and other macro economic challenges currently affecting us;

•     changes in product mix, market mix and product pricing, particularly relating to the expansion of the systems business;

•     increase in costs of manufacturing and operating costs;

•     our ability to obtain regulatory approval or market acceptance of new technologies, enforce patents and protect proprietary products and manufacturing techniques;

•     fluctuations in our effective tax rate;

•     our ability to successfully complete or integrate any acquisitions;

•     the impact of pricing and other actions by competitors; and

•     our ability to achieve the savings anticipated from cost reduction and gross margin improvement initiatives.

RISK FACTORS

An investment in our securities involves certain risks. You should carefully consider the risk factors discussed under the heading “Cautionary Statement Concerning Forward-Looking Statements” provided at the beginning of this prospectus, the risks described under “Risk Factors” in our most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q, as well as the other information included or incorporated by reference in this prospectus, before making an investment decision. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business or financial performance. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The market or trading price of our securities could decline due to any of these risks or other factors, and you may lose all or part of your investment.

USE OF PROCEEDS

Unless the applicable prospectus supplement indicates otherwise, we intend to use net proceeds from the sale of the debt securities for general corporate purposes, including to refinance or repay outstanding indebtedness if so specified in the applicable prospectus supplement. We may temporarily invest funds that are not immediately needed for these purposes in short-term marketable securities.

RATIO OF EARNINGS TO FIXED CHARGES

Our ratio of earnings to fixed charges for the nine months ended April 30, 2010 and each of the five years in the period ended July 31, 2009 is set forth below. For the purpose of computing these ratios, “earnings” consists of income before provision for income taxes and cumulative effect of a change in accounting principles, plus fixed charges (excluding capitalized interest). “Fixed charges” consists of interest expense (which includes amortization of debt issue costs), capitalized interest and a portion of rentals deemed to be interest.

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture. In addition, we will describe in the applicable prospectus supplement, material United States (“U.S.”) federal tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. Any taxes withheld or deducted from payments in respect of the debt securities and paid to the relevant tax authority shall be deemed to have been paid to the applicable holder. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 and any integral multiples thereof. Subject to the limitations provided in the indenture and in the applicable prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the corporate office of the trustee or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Global Securities

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

Events of Default

Under the terms of the indenture, each of the following constitutes an event of default for a series of debt securities unless it is either inapplicable to a particular series or it is specifically deleted or modified:

•     default for 30 days in the payment of any interest when due;

•     default in the payment of principal, or premium, if any, when due;

•     default for 30 days in the payment of any sinking fund installment, if any, when due;

5

•     default in the performance, or breach, of any covenant or agreement in the indenture for 90 days after written notice;

•     default in the payment of any principal of any of our indebtedness for money borrowed (other than any indebtedness owing to any of our subsidiaries) in a principal amount in excess of $50,000,000 (or the foreign currency equivalent at the time) at the stated final maturity thereof or the occurrence of any other default resulting in the acceleration prior to the stated maturity thereof, if such indebtedness is not discharged or such acceleration is not rescinded or annulled within 30 days after written notice to us by the trustee or to us and the trustee by the holders of not less than 25% in principal amount of the applicable series then outstanding, provided that the resulting event of default under the indenture with respect to such series will be deemed cured or waived, without any further action by us or any other person, if such other default is cured by us or waived by the holders of such indebtedness;

•     certain events of bankruptcy, insolvency or reorganization; and

•     any other event of default described in the applicable company order or supplemental indenture under which the series of debt securities is issued.

We are required to furnish the trustee annually with an officer’s certificate as to our compliance with all conditions and covenants under the indenture. The indenture provides that the trustee may withhold notice to you of any default, except in respect of the payment of the principal of, premium, if any, or interest on the debt securities, if it considers it in the interests of the holders of the debt securities to do so.

Effect of an Event of Default

If an event of default exists (other than an event of default in the case of certain events of bankruptcy), the trustee or the holders of not less than 25% in aggregate principal amount of a series of outstanding debt securities may declare the principal amount, or, if the debt securities are original issue discount securities, the portion of the principal amount as may be specified in the terms of that series, of and all accrued but unpaid interest on all outstanding debt securities of that series to be due and payable immediately, by a notice in writing to us, and to the trustee if given by holders. Upon that declaration the principal (or specified) amount will become immediately due and payable. However, at any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the event of default may, without further act, be deemed to have been waived and such declaration may, without further act, be deemed to have been rescinded and annulled subject to conditions specified in the indenture.

If an event of default in the case of certain events of bankruptcy, insolvency or reorganization exists, the principal amount of all debt securities outstanding under the indenture shall automatically, and without any declaration or other action on the part of the trustee or any holder of such outstanding debt, become immediately due and payable.

Subject to the provisions of the indenture relating to the duties of the trustee, if an event of default then exists, the trustee will be under no obligation to exercise any of its rights or powers under the indenture (other than the payment of any amounts on the debt securities furnished to it pursuant to the indenture) at your (or any other person’s) request, order or direction, unless you have (or such other person has) offered to the trustee reasonable security or indemnity. Subject to the provisions for the security or indemnification of the trustee, the holders of a majority in aggregate principal amount of a series of outstanding debt securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee in connection with the debt securities of that series.

6

Legal Proceedings and Enforcement of Right to Payment

You will not have any right to institute any proceeding in connection with the indenture or for any remedy under the indenture, unless you have previously given to the trustee written notice of a continuing event of default with respect to debt securities of that series. In addition, the holders of at least 25% in aggregate principal amount of a series of the outstanding debt securities must have made written request, and offered reasonable security or indemnity, to the trustee to institute that proceeding as trustee, and, within 60 days following the receipt of that notice, the trustee must not have received from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series a direction inconsistent with that request, and must have failed to institute the proceeding. However, you will have an absolute and unconditional right to receive payment of the principal of, premium, if any, and interest on that debt security on or after the due dates expressed in the debt security and to institute a suit for the enforcement of that payment.

Modification and Waiver

Modification

We and the trustee may modify and amend the indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected. However, no modification or amendment may, without the consent of the holder of each outstanding debt security affected:

•     extend the stated maturity of the principal of, or any installment of interest on, any outstanding debt security;

•     reduce the principal amount of or the interest on or any premium payable upon the redemption of any outstanding debt security;

•     change the currency in which the principal amount of and premium, if any, or interest on any outstanding debt security is denominated or payable;

•     reduce the principal amount of an original issue discount security that would be due and payable upon a declaration of acceleration of the maturity thereof;

•     impair your right to institute suit for the enforcement of any payment on any outstanding debt security after the stated maturity or redemption date;

•     materially adversely affect the economic terms of any right to convert or exchange any outstanding debt security;

•     reduce the percentage of the holders of outstanding debt securities necessary to modify or amend the indenture or to waive compliance with certain provisions of the indenture or certain defaults and consequences of such defaults; or

•     modify any of these provisions or any of the provisions relating to the waiver of certain past defaults or certain covenants, except to increase the required percentage to effect such action or to provide that certain other provisions may not be modified or waived without the consent of all of the holders of the debt securities affected.

7

Waiver

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all debt securities of that series, waive compliance by us with certain restrictive covenants of the indenture.

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all debt securities of that series, generally waive any past default under the indenture and the consequences of such default. However, a default in the payment of the principal of, or premium, if any, or any interest on, any debt security of that series cannot be so waived.

Merger, Consolidation and Sale of Assets

We will not consolidate with or merge into any other entity or sell other than for cash or lease all or substantially all our assets to another entity, or purchase all or substantially all the assets of another entity, and no entity may consolidate with or merge into us, unless:

•     we will be the continuing entity in any merger or consolidation or the successor, transferee or lessee entity (if other than us) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations relating to the debt securities;

•     immediately after such consolidation, merger, sale, lease or purchase, there exists no event of default, and no event which, after notice or lapse of time or both, would become an event of default; and

•     other conditions described in the indenture are met.

This covenant would not apply to a purchase by a subsidiary of all or substantially all of the assets of another entity.

Defeasance and Covenant Defeasance

The indenture provides that we may discharge all of our obligations with respect to any series of the debt securities at any time, and that we may also be released from our obligations under certain covenants and from certain other obligations, including obligations imposed by a company order or supplemental indenture with respect to that series, if any, and elect not to comply with those sections and obligations without creating an event of default. Discharge under the first procedure is called “defeasance” and under the second procedure is called “covenant defeasance.”

Defeasance or covenant defeasance may be effected only if:

•     we irrevocably deposit with the trustee money or U.S. government obligations or a combination thereof, as trust funds in an amount sufficient to pay and discharge each installment of principal of, premium, if any, and interest on, all outstanding debt securities of that series;

•     no event of default under the indenture has occurred and is continuing on the date of such deposit, other than an event of default resulting from the borrowing of funds and the grant of any related liens to be applied to such deposit; and

8

•     we deliver to the trustee an opinion of counsel to the effect that (i) the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge or as a result of the deposit and covenant defeasance and (ii) the deposit, defeasance and discharge or the deposit and covenant defeasance will not otherwise alter those holders’ U.S. federal income tax treatment of principal and interest payments on the debt securities of that series and, in the case of a defeasance, this opinion is accompanied by a ruling to that effect received from or published by the Internal Revenue Service.

Governing Law

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York.

Concerning the Trustee

The trustee under the indenture will have all the duties and responsibilities of an indenture trustee specified in the Trust Indenture Act. The trustee is not required to expend or risk its own funds or otherwise incur financial liability in performing its duties or exercising its rights and powers if it reasonably believes that it is not reasonably assured of repayment or adequate indemnity.

PLAN OF DISTRIBUTION

We may sell the offered debt securities:

•     to or through underwriters or dealers;

•     to or through agents;

•     directly to one or more purchasers;

•     through any combination of these methods; or

•     through any other means described in a prospectus supplement.

We may distribute the debt securities from time to time in one or more transactions, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices. In some cases, we or dealers acting with or on behalf of us may also purchase the debt securities and reoffer them to the public.

Underwriters, dealers and agents that participate in the distribution of the offered debt securities may be underwriters as defined in the Securities Act of 1933, as amended (the “Securities Act”), and any discounts or commissions received by them from us and any profit on the resale of the offered debt securities by them may be treated as underwriting discounts and commissions under the Securities Act. We will identify any managing underwriter, other underwriters or agents, and describe their compensation and the terms of the transactions, in a prospectus supplement.

If we use underwriters in the sale, we will execute an underwriting agreement with the underwriters at the time we reach an agreement for the sale of the debt securities. The underwriters will acquire the debt securities for their own account. The underwriters may resell the debt securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the debt securities will be subject to certain conditions. The underwriters will be obligated to purchase all of the debt securities offered if any of the debt securities are purchased. The underwriters may change from time to time any initial public offering price and any discount or concession allowed or re-allowed or paid to dealers.

We may sell the offered debt securities through agents designated by us. Unless indicated in the applicable prospectus supplement, any agents will agree to use their reasonable best efforts to solicit purchases for the period of their appointment.

If we use dealers in the sale, we will sell the debt securities to the dealer, as principal. The dealer will then sell the debt securities to the public at varying prices that the dealer will determine at the time it sells the debt securities.

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on a national securities exchange or a foreign securities exchange. Each series of debt securities may be a new issue of securities with no established trading market. Underwriters and agents may, from time to time, purchase and sell the debt securities described in this prospectus and the relevant prospectus supplement in the secondary market, but are not obligated to do so. No assurance can be given that there will be a secondary market for the debt securities or liquidity in the secondary market if one develops. From time to time, underwriters and dealers may make a market in the debt securities.

We may authorize agents and underwriters to solicit offers by certain institutions to purchase the debt securities at the public offering price under delayed delivery contracts. If we use delayed delivery contracts,

we will disclose that we are using them in the prospectus supplement and will tell you when we will demand payment and delivery of the debt securities under the delayed delivery contracts. These delayed delivery contracts will be subject only to the conditions that we describe in the prospectus supplement. We will describe in the applicable prospectus supplement the commission that underwriters and agents soliciting purchases of the debt securities under delayed contracts will be entitled to receive.

In compliance with guidelines of the Financial Industry Regulatory Authority (“FINRA”), the maximum consideration or discount to be received by any FINRA member will not exceed 8% of the aggregate amount of the debt securities offered pursuant to this prospectus and any applicable prospectus supplement.

Any underwriter, agent or dealer utilized in the initial offering of debt securities will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

In connection with underwritten offerings of the offered debt securities and in accordance with applicable law and industry practice, the underwriters in certain circumstances are permitted to engage in certain transactions that stabilize the price of the debt securities. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the debt securities. If the underwriters create a short position in the debt securities in connection with the offering, i.e., if they sell more debt securities than are set forth on the cover page of the applicable prospectus supplement, the underwriters may reduce that short position by purchasing debt securities in the open market. The underwriters also may impose a penalty bid on certain underwriters. This means that if the underwriters purchase the debt securities in the open market to reduce the underwriters’ short position or to stabilize the price of the debt securities, they may reclaim the amount of the selling concession from the underwriters who sold those debt securities as part of the offering. In general, purchases of a debt security for the purpose of stabilization or to reduce a short position could cause the price of the debt security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a debt security to the extent that it were to discourage resales of the debt security.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments which the underwriters, dealers or agents may be required to make. Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of their businesses.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the debt securities offered hereby will be passed upon for us by Cleary Gottlieb Steen & Hamilton LLP, our New York counsel.

Item 15.   Indemnification of Directors and Officers.

Section 721 of the New York Business Corporation Law (the “NYBCL”) provides that, in addition to indemnification provided in Article 7 of the NYBCL, a corporation may indemnify a director or officer by a provision contained in the certificate of incorporation or by-laws or by a resolution of its shareowners or directors or by agreement, provided that no indemnification may be made to or on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that such director or officer personally gained in fact a financial profit or other advantage to which he was not legally entitled.

Section 722(a) of the NYBCL provides that a corporation may indemnify a director or officer made, or threatened to be made, a party to any action or proceeding other than a derivative action, whether civil or criminal, by reason of the fact that he was a director or officer of the corporation, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys’ fees, actually and necessarily incurred as a result of such action or proceeding or any appeal therein, if such director or officer acted in good faith, for a purpose which he reasonably believed to be in the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his conduct was unlawful.

II-1

Section 722(c) of the NYBCL provides that a corporation may indemnify a director or officer, made or threatened to be made a party in a derivative action, by reason of the fact that he was a director or officer of the corporation, against amounts paid in settlement and reasonable expenses, including attorneys’ fees, actually and necessarily incurred by him in connection with the defense or settlement of such action or in connection with an appeal therein, if such director or officer acted in good faith, for a purpose which he reasonably believed to be in the best interests of the corporation, except that no indemnification will be available under Section 722(c) of the NYBCL in respect of a threatened or pending action which is settled or otherwise disposed of, or any claim, issue or matter as to which such director or officer shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines upon application that, in view of all the circumstances of the case, the director or officer is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Section 723 of the NYBCL specifies the manner in which payment of indemnification under Section 722 of the NYBCL or indemnification permitted under Section 721 of the NYBCL may be authorized by the corporation. It provides that indemnification may be authorized by the corporation, and that that indemnification by a corporation is mandatory in any case in which the director or officer has been successful, whether on the merits or otherwise, in defending an action or proceeding. In the event that the director or officer has not been successful or the action is settled, indemnification must be authorized by the appropriate corporate action as set forth in Section 723.

Section 724 of the NYBCL provides that, upon application by a director or officer, indemnification may be awarded by a court to the extent authorized. Section 722 and Section 723 of the NYBCL contain certain other miscellaneous provisions affecting the indemnification of directors and officers.

Section 726 of the NYBCL authorizes the purchase and maintenance of insurance to indemnify (1) a corporation for any obligation which it incurs as a result of the indemnification of directors and officers under the provisions of Article 7 of the NYBCL, (2) directors and officers in instances in which they may be indemnified by the corporation under the provisions of Article 7, and (3) directors and officers in instances in which they may not otherwise be indemnified by the corporation under the provisions of Article 7, provided the contract of insurance covering such directors and officers provides, in a manner acceptable to the New York State Superintendent of Insurance, for a retention amount and for co-insurance. Section 726(b) sets forth certain payments for which insurance cannot be provided.

Paragraph 7 of the Certificate of Incorporation of the Company provides in part as follows:

“To the fullest extent permitted by the New York Business Corporation Law as in effect on November 20, 1987 or, if thereafter amended, as so amended, a director of the corporation shall not be liable to the corporation or its shareholders or any of them for damages for any breach of duty as a director.”

Article VII of the By-Laws of the Company provides as follows:

“Section 7.01 Indemnification by the Corporation.  The corporation shall, to the fullest extent permitted by applicable law, indemnify any person made or threatened to be made a party to any action or proceeding, whether civil, criminal, administrative or investigative (and whether or not (i) by or in the right of the corporation to procure a judgment in its favor or (ii) by or in the right of any Other Entity (as defined below) which such person served in any capacity at the request of the corporation, to procure a judgment in its favor), by reason of the fact that such person, or his or her testator or intestate, is or was a director or officer of the corporation or served such Other Entity in any capacity at the request of the corporation, against all judgments, fines, amounts paid in settlement and all expenses, including attorneys’ and other experts’ fees, costs and disbursements, actually and reasonably incurred by such person as a result of such action or proceeding, or any appeal therein, or

II-2

actually and reasonably incurred by such person (a) in making an application for payment of such expenses before any court or other governmental body, or (b) in otherwise seeking to enforce the provisions of this Section 7.01, or (c) in securing or enforcing such person’s rights under any policy of director or officer liability insurance provided by the corporation, if such person acted in good faith, for a purpose which he or she reasonably believed to be in, or, in the case of services for any Other Entity, not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his or her conduct was unlawful. The termination of any action or proceeding by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not in itself create a presumption that such person did not act in good faith, for a purpose which he or she reasonably believed to be in, or, in the case of service for any Other Entity, not opposed to, the best interests of the corporation or that he or she had reasonable cause to believe that his or her conduct was unlawful.

However, (i) no indemnification may be made to or on behalf of any such person if a judgment or other final adjudication adverse to such person establishes that his or her acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled; (ii) no indemnification may be made if there has been a settlement approved by the court and the indemnification would be inconsistent with any condition with respect to indemnification expressly imposed by the court in approving the settlement; and (iii) in the event of a proceeding by or in the right of the corporation to procure a judgment in its favor, no indemnification may be made if it is settled or otherwise disposed of or such person shall have been finally adjudged liable to the corporation, unless (and only to the extent that) the court in which the action was brought, or if no action was brought, any court of competent jurisdiction, determines upon application that, in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Any expense described in the first paragraph of this Section 7.01 that is incurred by any person entitled to indemnification under this Section 7.01 shall be paid or reimbursed to such person by the corporation in advance of the final disposition of any related action or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount to the corporation to the extent, if any, that such person (i) is ultimately found not to be entitled to indemnification or (ii) receives reimbursement for such expenses under a policy of insurance paid for by the corporation. Such advances shall be paid by the corporation to such person within twenty days following delivery of a written request therefor by such person to the corporation. No payment made by the corporation pursuant to this paragraph shall be deemed or construed to relieve the issuer of any insurance policy of any obligation or liability which, but for such payment, such insurer would have to the corporation or to any director or officer of the corporation or other individual to whom or on whose behalf such payment is made by the corporation.

The rights to indemnification and advancement of expenses provided by this Section 7.01:

(i) shall be deemed at all times (whether before or after the adoption of this Section 7.01) to constitute contract rights, as if the provisions of this Section 7.01 were set forth in a separate written contract between each director, officer or other person entitled to indemnification hereunder and the corporation, and the corporation intends to be legally bound to such person (with respect to current directors, officers or employees of the corporation, the rights conferred under this Section 7.01 are present contractual rights and such rights are fully vested, and shall be deemed to have vested fully, immediately upon adoption of this Section 7.01; with respect to any directors, officers or employees of the corporation who commence service following adoption of this Section 7.01, the rights conferred under this provision shall be present contractual rights and such rights shall fully vest, and

II-3

be deemed to have vested fully, immediately upon such director, officer or employee commencing service);

(ii) shall continue as to the person entitled to indemnification hereunder even though he or she may have ceased to serve in the capacity that entitles him or her to indemnification at the time of the action or proceeding; and

(iii) shall inure to the benefit of the heirs, executors and administrators of such person.

A person who has been successful, on the merits or otherwise, in the defense of a civil or criminal action or proceeding of the character described in this Section 7.01 shall be entitled to (i.e., has a legally binding right against the corporation to) the indemnification authorized by this Section 7.01. Except as provided in the immediately preceding sentence, any indemnification provided for in this Section 7.01 (unless ordered by a court under Section 724 of the Business Corporation Law), shall be made by the corporation only if authorized in the specific case:

(1) By the board of directors acting by a quorum consisting of directors who are not parties to such action or proceeding for which indemnification is sought, upon a finding that the person seeking indemnification has met the standard of conduct set forth in the first two paragraphs of this Section 7.01, or,

(2) If a quorum under the immediately preceding subparagraph is not obtainable or, even if obtainable, a quorum of disinterested directors so directs:

(A) by the board upon the opinion in writing of independent legal counsel that indemnification is proper in the circumstances because the applicable standard of conduct set forth in said first two paragraphs has been met by such person, or

(B) by the shareholders upon a finding that the person has met the applicable standard of conduct set forth in said first two paragraphs.

Notwithstanding any other provision hereof, no amendment or repeal of this Section 7.01, or any other corporate action or agreement which prohibits or otherwise limits, reduces or eliminates the right of any person under this Section 7.01, including the right to indemnification or advancement or reimbursement of reasonable expenses hereunder, nor a decision by the board of directors that an individual designated an Elected Officer shall no longer be an Elected Officer shall be effective as to any person until the 60th day following notice to such person of such action, and no such amendment or repeal or other corporate action or agreement shall deprive any person of any right hereunder arising out of or with respect to any alleged or actual act or omission occurring prior to such 60th day.

The corporation is hereby authorized, but shall not be required, to enter into agreements with any of its directors, officers or employees providing for rights to indemnification and advancement and reimbursement of reasonable expenses, including attorneys’ fees, to the extent permitted by law, but the corporation’s failure to do so shall not in any manner affect or limit the rights provided for by this Section 7.01 or otherwise.

For purposes of this Section 7.01, the term “the corporation” shall include any legal successor to the corporation, including any corporation which acquires all or substantially all of the assets of the corporation in one or more transactions, and the term “Other Entity” shall mean a corporation (other than the corporation) of any type or kind, domestic or foreign, or any partnership, joint venture, trust, employee benefit plan or other enterprise. For purposes of this Section 7.01, the corporation shall be deemed to have requested a person to serve an employee benefit plan where the

II-4

performance by such person of his or her duties to the corporation or any subsidiary thereof also imposes duties on, or otherwise involves services by, such person to the plan or participants or beneficiaries of the plan; excise taxes assessed on a person with respect to an employee benefit plan pursuant to applicable law shall be considered fines; and action taken or omitted by a person with respect to any employee benefit plan in the performance of such person’s duties for a purpose reasonably believed by such person to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of the corporation.

Section 7.02 Non-Exclusivity.  The rights granted pursuant to or provided by the provisions of Section 7.01 to any person shall be in addition to and shall not be exclusive of any other rights to indemnification and expenses to which any such person may otherwise be entitled by law, contract or otherwise.”

The Company has purchased liability insurance for its officers and directors as permitted by Section 726 of the NYBCL.

Item 17.   Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth

II-5

in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) If the registrant is relying on Rule 430B:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the

II-6

registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual reports pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.
