OUR COMPANY

     NRG Energy, Inc., or NRG or the Company, is a wholesale power generation company with a significant presence in major competitive power markets in the United States. NRG is engaged in the ownership, development, construction and operation of power generation facilities, the transacting in and trading of fuel and transportation services, and the trading of energy, capacity and related products in the regional markets in the US and select international markets where its generating assets are located.

     As of December 31, 2008, NRG had a total global portfolio of 189 active operating fossil fuel and nuclear generation units, at 48 power generation plants, with an aggregate generation capacity of approximately 24,005 MW, and approximately 550 MW under construction which includes partners’ interests of 275 MW. In addition, NRG has ownership interests in two wind farms representing an aggregate generation capacity of 270 MW, which includes partner interests of 75 MW. Within the US, NRG has one of the largest and most diversified power generation portfolios in terms of geography, fuel-type and dispatch levels, with approximately 22,925MWof fossil fuel and nuclear generation capacity in 177 active generating units at 43 plants and ownership interests in two wind farms representing 195MWof wind generation capacity. These power generation facilities are primarily located in Texas (approximately 11,010 MW, including the 195 MW from the two wind farms), the Northeast (approximately 7,020 MW), South Central (approximately 2,845 MW), and West (approximately 2,130 MW) regions of the US, and approximately 115 MW of additional generation capacity from the Company’s thermal assets.

     NRG’s principal domestic power plants consist of a mix of natural gas-, coal-, oil-fired, nuclear and wind facilities, representing approximately 45%, 33%, 16%, 5% and 1% of the Company’s total domestic generation capacity, respectively. In addition, 15% of NRG’s domestic generating facilities have dual or multiple fuel capacity, which allows plants to dispatch with the lowest cost fuel option.

     NRG’s domestic generation facilities consist of intermittent, baseload, intermediate and peaking power generation facilities, the ranking of which is referred to as Merit Order, and include thermal energy production plants. The sale of capacity and power from baseload generation facilities accounts for the majority of the Company’s revenues and provides a stable source of cash flow. In addition, NRG’s generation portfolio provides the Company with opportunities to capture additional revenues by selling power during periods of peak demand, offering capacity or similar products to retail electric providers and others, and providing ancillary services to support system reliability. We were incorporated as a Delaware corporation on May 29, 1992. Our common stock is listed on the New York Stock Exchange under the symbol “NRG”. Our headquarters and principal executive offices are located at 211 Carnegie Center, Princeton, New Jersey 08540. Our telephone number is (609) 524-4500. Our website is www.nrgenergy.com.

     We have summarized certain general features of the debt securities from the indenture. A form of indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The following description of the terms of the debt securities and the guarantees sets forth certain general terms and provisions. The particular terms of the debt securities and guarantees offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities and guarantees will be described in the related prospectus supplement. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the related prospectus supplement and to the following description.

     United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable prospectus supplement.

     Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional United States federal income tax considerations will be set forth in the applicable prospectus supplement.

     The term “debt securities” includes debt securities denominated in U.S. dollars or, if specified in the applicable prospectus supplement, in any other freely transferable currency or units based on or relating to foreign currencies.

     We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 or $5,000 and any integral multiples thereof. Subject to the limitations provided in the indenture and as otherwise described in the prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the office of the trustee maintained in the Borough of Manhattan, The City of New York 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.

Guarantees

     Any debt securities may be guaranteed by one or more of our direct or indirect subsidiaries. Each prospectus supplement will describe any guarantees for the benefit of the series of debt securities to which it relates, including required financial information of the subsidiary guarantors, as applicable.

DESCRIPTION OF PREFERRED STOCK

     The following briefly summarizes the general terms of the preferred stock we may offer, other than pricing and related terms that will be disclosed in an accompanying prospectus supplement. You should read the particular terms of any series of preferred stock offered by us, which will be described in more detail in any prospectus supplement relating to such series, together with the more detailed provisions of our Amended and Restated Certificate of Incorporation and the certificate of designation relating to each particular series of preferred stock for provisions that may be important to you. The Amended and Restated Certificate of Incorporation is incorporated by reference into the registration statement of which this prospectus forms a part. The certificate of designation relating to the particular series of preferred stock offered by an accompanying prospectus supplement and this prospectus will be filed as an exhibit to a document incorporated by reference in the registration statement. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.

     As of the date of this prospectus, we are authorized to issue up to 10,000,000 shares of preferred stock, par value $0.01 per share. As of February 12, 2009, 419,900 shares of 4% Convertible Perpetual Preferred Stock were outstanding, 250,000 shares of 3.625% Convertible Perpetual Preferred Stock were outstanding, and 1,699,280 shares of the 5.75% Mandatory Convertible Preferred Stock were outstanding.

     Under our Amended and Restated Certificate of Incorporation, our Board of Directors is authorized to issue shares of preferred stock in one or more series, and to establish from time to time a series of preferred stock with the following terms specified:

• the number of shares to be included in the series;

• the designation, powers, preferences and rights of the shares of the series; and

• the qualifications, limitations or restrictions of such series.

     Prior to the issuance of any series of preferred stock, our Board of Directors will adopt resolutions creating and designating the series as a series of preferred stock and the resolutions will be filed in a certificate of designation as an amendment to the Amended and Restated Certificate of Incorporation. The term “Board of Directors” includes any duly authorized committee.

     The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future. Our Board of Directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our or our subsidiaries’ officers, directors and employees pursuant to benefit plans or otherwise. Shares of preferred stock we issue may have the effect of rendering more difficult or discouraging an acquisition of us deemed undesirable by our Board of Directors.

     The preferred stock will be, when issued, fully paid and nonassessable. Holders of preferred stock will not have any preemptive or subscription rights to acquire more of our stock.

7

     The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.

Rank

     Unless otherwise specified in the prospectus supplement relating to the shares of a series of preferred stock, such shares will rank on an equal basis with each other series of preferred stock and prior to the common stock as to dividends and distributions of assets.

Dividends

     Holders of each series of preferred stock will be entitled to receive dividends when, as and if declared by our Board of Directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books or, if applicable, the records of the depositary referred to below on the record dates fixed by the Board of Directors. Dividends on a series of preferred stock may be cumulative or noncumulative.

     We may not declare, pay or set apart for payment dividends on the preferred stock unless full dividends on other series of preferred stock that rank on an equal or senior basis have been paid or sufficient funds have been set apart for payment for

• all prior dividend periods of other series of preferred stock that pay dividends on a cumulative basis; or

• the immediately preceding dividend period of other series of preferred stock that pay dividends on a noncumulative basis.

     Partial dividends declared on shares of preferred stock and each other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for each series of preferred stock.

     Similarly, we may not declare, pay or set apart for payment non-stock dividends or make other payments on the common stock or any other of our stock ranking junior to the preferred stock until full dividends on the preferred stock have been paid or set apart for payment for

• all prior dividend periods if the preferred stock pays dividends on a cumulative basis; or

• the immediately preceding dividend period if the preferred stock pays dividends on a noncumulative basis.

Conversion and Exchange

     The prospectus supplement for a series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for shares of our common stock, our preferred stock, our other securities or the debt or equity securities of one or more other entities.

Redemption and Sinking Fund

     If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or the option of the holder thereof and may be mandatorily redeemed. Any partial redemptions of preferred stock will be made in a way that the Board of Directors decides is equitable.

     Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

     No series of preferred stock will receive the benefit of a sinking fund except as set forth in the applicable prospectus supplement.

Liquidation Preference

     Upon any voluntary or involuntary liquidation, dissolution or winding up, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement

8

relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Such distributions will be made before any distribution is made on any securities ranking junior relating to liquidation, including common stock.

     If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of our available assets on a ratable basis in proportion to the full liquidation preferences. Holders of such series of preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.

Voting Rights

     The holders of shares of preferred stock will have no voting rights, except:

• as otherwise stated in the prospectus supplement;

• as otherwise stated in the certificate of designation establishing such series; and

• as required by applicable law.

     At each annual meeting of stockholders, our directors are elected to hold office until the expiration of the term for which they are elected, and until their successors have been duly elected and qualified; except that if any such election is not so held, such election will take place at a stockholders’ meeting called and held in accordance with the Delaware General Corporation Law (“DGCL”). Our directors are divided into three classes as nearly equal in size as is practicable, designated Class I, Class II and Class III. At each annual meeting, directors to replace those of a class whose terms expire at such annual meeting will be elected to hold office until the third succeeding annual meeting and until their respective successors have been duly elected and qualified. If the number of directors is changed, any newly created directorships or decrease in directorships will be so apportioned among the classes as to make all classes as nearly equal in number as practicable.

Item 15. Indemnification of Directors and Officers.

Delaware

     Section 145 of the DGCL authorizes a corporation, subject to the procedures and limitations stated therein, to indemnify its directors, officers, employees and agents against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement reasonably incurred provided they act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, they had no reasonable cause to believe their conduct was unlawful. In the case of proceedings brought by or on behalf of the corporation, indemnification is limited to expenses and is not permitted if the individual is adjudged liable to the corporation, unless the court determines otherwise. The statute provides that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under any by-law, agreement, vote of stockholders or disinterested directors or otherwise.

     Article NINE of our Amended and Restated Certificate of Incorporation provides for the limitation of liability of directors and for the indemnification of directors and officers. Article NINE states that to the fullest extent permitted by the DGCL, and except as otherwise provided in our Amended and Restated By-laws, (i) no director of the Company shall be liable to the Company or its stockholders for monetary damages arising from a breach of fiduciary duty owed to the Company or its stockholders; and (ii) the Company shall indemnify its officers and directors.

     Set forth below are material provisions of Article FIVE of our by-laws that authorize the indemnification of directors and officers:

• Section 1 of Article FIVE provides that our directors and officers shall be indemnified and held harmless by the Company to the fullest extent authorized by the DGCL. In addition, this right of indemnification continues to persons who have ceased to be our directors or officers and to his or her heirs, executors and administrators; provided, however, that, except with respect to proceedings to enforce rights to indemnification, the Company shall not indemnify any such indemnitee in connection with a proceeding

II-1

	initiated by such indemnitee except to the extent such proceeding was authorized in writing by the Board of Directors of the Company.
•	Section 3 of Article FIVE provides that the Company may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director, officer, employee or agent of the Company against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, whether or not the Company would have the power to indemnify such person against such expenses, liability or loss under the DGCL.
•	Section 5 of Article FIVE provides that the rights to indemnification conferred in Article FIVE of our by-laws and in our certificate of incorporation shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise.

The bylaws of Texas Genco Financing Corp. provide, subject to certain exceptions, for the indemnification of all current and former directors, officers, employees or agents against expenses, judgments, fines and amounts paid in connection with actions to which such person is a party by reason of the fact that he or she was a director, officer, employee or agent of the corporation, except that the corporation shall be required to indemnify a person for an action initiated by that person only if the proceeding was authorized by the board of directors.

Virginia

     Sections 13.1-697, -698, -699, -701, -702, -703 and -704 of the Virginia Stock Corporation Act (“VSCA”) provide, generally and in part, that a corporation may indemnify an individual made a party to a proceeding because he is or was a director, against liability incurred in the proceeding if he conducted himself in good faith and reasonably believed, in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests, or in all other cases, that his conduct was at least not opposed to its best interests and, in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful; provided, however, that a corporation may not indemnify a director in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation or in connection with any other proceeding charging improper personal benefit to him in which he was adjudged liable. Such indemnification in connection with a proceeding by or in the right of the corporation is limited to reasonable expenses incurred in connection therewith. Unless limited by a corporation’s certificate of incorporation, similar indemnity with respect to expenses incurred is mandatory under the above-referenced Sections of the VSCA for a director or officer who was wholly successful on the merits or otherwise, in defense of any proceedings to which he was a party because he is or was a director or officer, as the case may be. Any such indemnification may be made only as authorized in each specific case after a determination by disinterested directors, special legal counsel or disinterested shareholders that indemnification is permissible because the indemnitee has met the applicable standard of conduct. Directors and officers may also apply for court-ordered indemnification. Pursuant to Section 13.1-704 of the VSCA, a corporation may also indemnify and advance expenses to any director or officer to the extent provided by the corporation’s certificate of incorporation, any bylaw made by the shareholders or any resolution adopted by the shareholders, except an indemnity against willful misconduct or a knowing violation of the criminal law.

     The bylaws of Chickahominy River Energy Corp. provide generally for the indemnification of directors and officers to the fullest extent authorized by the VSCA, except that the corporation shall only be required to indemnify a person for an action initiated by that person if the proceeding was authorized by the board of directors.

California

     Section 317 of the California General Corporation Law (“CAGCL”) authorizes a court to award, or a corporation to grant, indemnity to officers, directors and other agents for reasonable expenses incurred in connection

II-3

with the defense or settlement of an action by or in the right of the corporation or in a proceeding by reason of the fact that the person is or was an officer, director, or agent of the corporation. Indemnity is available where the person party to a proceeding or action acted in good faith and in a manner reasonably believed to be in the best interests of the corporation and its shareholders and, with respect to criminal actions, had no reasonable cause to believe his conduct was unlawful. To the extent a corporation’s officer, director or agent is successful on the merits in the defense of any proceeding or any claim, issue or related matter, that person shall be indemnified against expenses actually and reasonably incurred. Under Section 317 of the CAGCL, expenses incurred in defending any proceeding may be advanced by the corporation prior to the final disposition of the proceeding upon receipt of any undertaking by or on behalf of the officer, director, employee or agent to repay that amount if it is ultimately determined that the person is not entitled to be indemnified. Indemnifications are to be made by a majority vote of a quorum of disinterested directors, or by approval of members not including those persons to be indemnified, or by the court in which such proceeding is or was pending upon application made by either the corporation, the agent, the attorney, or other person rendering services in connection with the defense. The indemnification provided by Section 317 is not exclusive of any other rights to which those seeking indemnification may be entitled.

     The charter documents of Hanover Energy Company authorize the corporation to provide indemnification of agents through bylaw provisions, agreements with agents, vote of shareholders or disinterested directors, or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the California Corporations code, subject only to the applicable limits set forth in Section 204 of the California Corporations Code with respect to actions for breach of duty to the corporation or its shareholders.

     The bylaws of Hanover Energy Company and Eastern Sierra Energy Company provide, subject to certain exceptions, to the fullest extent permissible under California law, for the indemnification of all current and former directors and officers in connection with actions to which such person is a party by reason of the fact that he or she was a director or officer of the corporation, except that the corporation shall only be required to indemnify a person for an action initiated by that person if the proceeding was authorized by the board of directors. The bylaws also provide that employees and agents may be indemnified by the company to subject to the terms of any agreement between the corporation and the person, be indemnified to the fullest extent permissible under California law.

     Section 17155 of the Beverly-Killea Limited Liability Company Act, which provides that, except for a breach of certain fiduciary duties, the articles of organization or written operating agreement of a limited liability company may provide for indemnification of any person, including, without limitation, any manager, member, officer, employee or agent of the limited liability company, against judgments, settlements, penalties, fines or expenses of any kind incurred as a result of acting in that capacity.

     The limited liability company agreement of Hoffman Summit Wind Project LLC provides, to the fullest extent permitted under California law, that the company may indemnify any member, manager, officer, employee or agent of the companies from and against any and all claims and demands arising by reason of the fact that such person is, or was, a member, manager, officer, employee or agent of the companies, provided the person acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, the best interests of the company.

     The bylaws of NEO Corporation provide that the corporation shall indemnify any person made or threatened to be made a party to a proceeding by reason of the former or present official capacity of the person acting for the corporation or acting in an official capacity with another entity at the direction or request of the corporation, according to the terms and under the procedures provided in Minnesota Statutes Section 302A.

     Article 2.02-1 of the Texas Business Corporation Act (“TXBCA”) authorizes a Texas corporation to indemnify a person who was, is, or is threatened to be made a named defendant or respondent in a proceeding, including any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative, or investigative because the person is or was a director. The TXBCA provides that unless a court of competent jurisdiction determines otherwise, indemnification is permitted only if it is determined that the person (1) conducted himself in good faith; (2) reasonably believed (a) in the case of conduct in his official capacity as a director of the corporation, that his conduct was in the corporation’s best interests; and (b) in all other cases, that his conduct was at least not opposed to the corporation’s best interests; and (3) in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. A person may be indemnified under Article 2.02-1 of the TXBCA against judgments, penalties (including excise and similar taxes), fines, settlements, and reasonable expenses actually incurred by the person (including court costs and attorneys’ fees), but if the person is found liable to the corporation or is found liable on the basis that personal benefit was improperly received by him, the indemnification is limited to reasonable expenses actually incurred and shall not be made in respect of any proceeding in which the person has been found liable for willful or intentional misconduct in the performance of his duty to the corporation. A corporation is obligated under Article 2.02-1 of the TXBCA to indemnify a director or officer against reasonable expenses incurred by him in connection with a proceeding in which he is named defendant or respondent because he is or was director or officer if he has been wholly successful, on the merits or otherwise, in the defense of the proceeding. Under Article 2.02-1 of the TXBCA a corporation may (1) indemnify and advance expenses to an officer, employee, agent or other persons who are or were serving at the request of the corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another entity to the same extent that it may indemnify and advance expenses to its directors, (2) indemnify and advance expenses to directors and such other persons identified in (1) to such further extent, consistent with law, as may be provided in the corporation’s articles of incorporation, bylaws, action of its board of directors, or contract or as permitted by common law and (3) purchase and maintain insurance or another arrangement on behalf of directors and such other persons identified in (1) against any liability asserted against him and incurred by him in such a capacity or arising out of his status as such a person.

     The bylaws of Texas Genco Holdings, Inc. provide for indemnification of directors and officers to the fullest extent permissible under Texas law. The bylaws also provide the company may indemnify any other agent of the company in connection with their agency to the fullest extent permissible under Texas law.

     Article 2.20 of the Texas Limited Liability Company Act authorizes a limited liability company to indemnify members and managers, officers, and other persons and purchase and maintain liability insurance for such persons. To the extent that at law or in equity, a member, manager, officer, or other person has duties (including fiduciary

II-5

duties) and liabilities relating thereto to a limited liability company or to another member or manager, such duties and liabilities may be expanded or restricted by provisions in the regulations.

     The regulations of Texas Genco GP, LLC provide for indemnification of members, managers, officers, employees or agents of the company to the full extent permissible under Texas law who are party to any action by reason of the indemnitee’s relation to the company, provided the indemnitee acted in good faith and in a manner the indemnitee reasonably believed to be in or not opposed to the best interests of the company, and, with respect to any criminal action or proceeding, did not have reasonable cause to believe the indemnitee’s conduct was unlawful.

     Article 11 of the Texas Revised Limited Partnership Act (“TRLPA”) provides for the indemnification of a general partner, limited partner, employee or agent by the limited partnership under certain circumstances against expenses and liabilities incurred in legal proceedings involving such persons because of their being or having been a general partner, limited partner, employee or agent of the limited partnership. Under the TRLPA, a limited partnership may purchase insurance on behalf of a general partner, limited partner, employee or agent of the limited partnership against any liability incurred regardless of whether the person could be indemnified under the TLRPA.

     The limited partnership agreements of NRG South Texas LP and Texas Genco Services, LP provide for the indemnification of any general partner, limited partner, employee or agent of the partnership to the fullest extent permissible under Texas law in any action to which the indemnitee becomes, or is threatened to be made, a respondent or defendant because of the indemnitee’s relation to the partnership. The partnerships may also purchase insurance against any liabilities incurred with regard to a general partner, limited partner, employee or agent.

Item 16. Exhibits.

     Reference is made to the attached Exhibit Index.

Item 17. Undertakings.

(a) Each of the undersigned registrants 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;
(ii)	To reflect in the prospectus any facts or events arising after the effective date of the 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 in the 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 a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii)	To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided,however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the 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, 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 initialbona fideoffering thereof.

II-6

(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 to any purchaser:

(i)

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

(ii)

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 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 initialbona fideoffering 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 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 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) Each of the undersigned registrants hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of such annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the 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 initialbona fideoffering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referred to in Item 15, or otherwise, each of the registrants 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

II-7

indemnification against such liabilities (other than the payment by such 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, such 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.
