DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of the Debt Securities that we may offer using this prospectus and the related indenture. This section is only a summary and does not purport to be complete. You must look to the relevant form of Debt Security and the indenture, as may be supplemented, for a full understanding of all terms of any series of Debt Securities. These forms and the indenture have been or will be filed or will be incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See "Where You May Find More Information About General Mills" for information on how to obtain copies.

A prospectus supplement will describe the specific terms of any particular series of Debt Securities, including any of the terms in this section that will not apply to that series, and any special considerations, including tax considerations, applicable to those Debt Securities. The prospectus supplement relating to each series of Debt Securities that we offer using this prospectus will be attached to the front of this prospectus. In some instances, certain of the precise terms of Debt Securities you are offered may be described in a further prospectus supplement, known as a "pricing supplement." If information in a prospectus supplement is inconsistent with the information in this prospectus, then the information in the prospectus supplement will apply and, where applicable, supersede the information in this prospectus.

We may issue an unlimited amount of Debt Securities using this prospectus. We may also issue Debt Securities pursuant to the indenture in transactions that are exempt from the registration requirements of securities laws.

General

We may issue any of our Debt Securities either separately or together with, on conversion of or in exchange for other securities.

None of the Debt Securities described in this prospectus will be secured by any of our property or assets. Accordingly, you will be one of our unsecured creditors.

We may issue Debt Securities as original issue discount securities, which are Debt Securities that are offered and sold at a discount, which may be substantial, below their stated principal amount. The prospectus supplement relating to any original issue discount securities will describe United States federal income tax consequences and other special considerations applicable to them. We may also issue Debt Securities as indexed securities or securities denominated in foreign currencies or currency units, which will be described in more detail in the prospectus supplement relating to those Debt Securities.

What is an Indenture?

As required by United States federal law for all bonds and notes of companies that are publicly offered, the Debt Securities will be governed by a document called an "indenture." An indenture is a contract between us and a trustee. The trustee has two main roles:

The Debt Securities will be issued under an indenture dated February 1, 1996, as supplemented, between us and U.S. Bank National Association, as trustee. We may issue as many distinct series of Debt Securities under the indenture as we wish. The indenture does not limit the principal amount of Debt Securities that we may issue under it. The indenture is governed by New York law and will be qualified under the Trust Indenture Act of 1939.

Our Trustee

U.S. Bank National Association, as trustee under the indenture, has been appointed by us as paying agent and registrar with regard to the Debt Securities. The trustee also acts as an agent for the issuance of our United States commercial paper. The trustee and its affiliates currently provide cash management and other banking and advisory services to us in the normal course of business and may from time to time in the future provide other banking and advisory services to us in the ordinary course of business, in each case in exchange for a fee.

Specific Terms of Each Series of Debt Securities

The prospectus supplement (including any separate pricing supplement) relating to any series of Debt Securities that we offer using this prospectus will describe the amount, price and other specific terms of the offered Debt Securities, including the following, if applicable:

Legal Ownership; Street Name and Indirect Holders; Global Securities

Who is the Legal Owner? Our obligations with respect to the Debt Securities, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to persons or entities who are the registered holders of the Debt Securities. We do not have direct obligations to investors who hold the Debt Securities indirectly, either because they choose to do so or because the relevant series of Debt Securities has been issued only in the form of global securities, as described below. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that registered holder is legally required to pass the payment along to you as an indirect holder but fails to do so.

What is "Street Name" Ownership? One common form of indirect ownership is known as holding in "street name." This is the phrase used to describe investors who hold securities in accounts at banks or brokers. We generally will not recognize investors who hold Debt Securities in this manner as the legal holders of those securities. Instead, we will generally recognize as the legal holder only the bank or broker or the financial institution that the bank or broker uses to hold the Debt Securities. The intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the Debt Securities, either because they agree to do so in the agreements with their customers or because they are legally required to do so.

6

If you hold Debt Securities in street name, you should check with your own institution to find out:

What is a Global Security? If we choose to issue Debt Securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. We do this by requiring that a global security be registered in the name of a financial institution that we select and by requiring that the Debt Securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below under "- Special Situations when a Global Security will be Terminated" occur. The financial institution that acts as the sole direct holder of the global security is called the depositary. Any person who wishes to own a Debt Security that is issued as a global security may only do so indirectly through an account with a broker, bank or other financial institution that in turn has an account with the depositary.

Special Investor Considerations for Global Securities. As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. We will not recognize the investor as a direct holder of Debt Securities and will instead deal only with the depositary that holds the global security. If you are an investor in Debt Securities that are issued only in the form of global securities, you should be aware that:

Special Situations when a Global Security will be Terminated. In a few special situations described below, a global security will terminate and interests in it will be exchanged for physical certificates representing the Debt Securities. After that exchange, the choice of whether to hold Debt Securities directly or in street name will be up to you. You must consult your own bank or broker to find out how to have your interests in Debt Securities transferred to your own name as the direct holder under these circumstances.

The special situations for termination of a global security are:

7

The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of Debt Securities covered by the prospectus supplement. When a global security terminates, the depositary, not us or the trustee, is responsible for determining the names of the institutions that will be the initial direct holders.

In the remainder of this description and in the descriptions of the terms of the Debt Securities, "you" means direct holders and not street name or other indirect holders.

Form, Exchange and Transfers

The Debt Securities will be issued only in fully registered form, without interest coupons, and unless otherwise indicated in the prospectus supplement, in denominations of $1,000 and any integral multiples of $1,000.

You may have your Debt Securities broken into more Debt Securities of smaller denominations or combined into fewer Debt Securities of larger denominations as long as the total principal amount of the series is not changed. This is called an exchange.

You may exchange or transfer Debt Securities at the office of the trustee. You will not be required to pay a service charge to transfer or exchange Debt Securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the entity performing the role of maintaining the list of registered direct holders, which is called the "security registrar," is satisfied with your proof of ownership.

The security registrar also serves as the transfer agent to perform transfers. The trustee will act as the security registrar and transfer agent. We may change this appointment to another entity or perform it ourselves. If we have designated other or additional registrars or transfer agents, they will be named in the prospectus supplement. We may cancel the designation of any particular registrar or transfer agent. We may also approve a change in the office through which any registrar or transfer agent acts.

If the Debt Securities of any series are redeemable and we redeem less than all of them, we may block the transfer or exchange of Debt Securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of Debt Securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any Debt Security being partially redeemed.

If a Debt Security is issued as a global security, only the depositary will be entitled to transfer and exchange the Debt Security as described in this section since the depositary will be the sole holder of the Debt Security. See "- Legal Ownership; Street Name and Indirect Holders; Global Securities" above.

Payment and Paying Agents

Unless we say otherwise in the applicable prospectus supplement, we will pay interest to you if you are a registered holder listed in the trustee's records at the close of business on a particular day in advance of each due date for interest, even if you no longer own the Debt Security on the interest due date. That particular day is called the regular record date and will be stated in the prospectus supplement.

Holders buying and selling Debt Securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the registered holder on the regular record date. The most common manner is to adjust the sales price of the Debt Securities to apportion interest fairly between buyer and seller.

We will pay interest, principal and any other money due on the Debt Securities at the corporate trust office of the trustee (which initially will also act as paying agent) in St. Paul, Minnesota. That office is currently located at 60 Livingston Avenue, St. Paul, Minnesota 55107. You must make arrangements to have your payments picked up at or wired from that office. We may also choose to pay interest by mailing checks directly to the registered holders at their address appearing in the security register.

We may also arrange for additional payment offices, and may cancel or change these offices, including our use of the trustee's corporate trust office. We may also authorize paying agents other than the trustee to make payments on the notes on our behalf, including choosing to act as our own paying agent. We must notify the trustee of changes in the paying agents for any particular series of Debt Securities.

Regardless of who acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount becomes due to direct holders will be repaid to us. After that two-year period, you may look only to us for payment and not to the trustee or any other paying agent.

8

If you are a street name or other indirect holder, you should consult your bank or broker for information on how you will receive payments.

Notices

We and the trustee will send notices regarding the Debt Securities only to direct holders, using their addresses as listed in the trustee's records.

Mergers and Similar Events

We are generally permitted under the indenture to consolidate or merge with another company. We are also permitted to sell or lease some or all of our assets to another company. However, we may not take any of these actions unless the following conditions, among others, are met:

You should know that there is no precise, established definition of what would constitute a sale or lease of substantially all of our assets under applicable law and, accordingly, there may be uncertainty as to whether a sale or lease of less than all of our assets would subject us to this provision.

If we merge out of existence or transfer (except through a lease) substantially all our assets, and the other firm becomes our successor and is legally responsible for the Debt Securities, we will be relieved of our own responsibility for the Debt Securities.

It is possible that the merger, sale of assets or other transaction would cause some of our property to become subject to a mortgage or other legal mechanism giving lenders preferential rights in our property over other lenders or over our general creditors if we fail to repay them. We have promised the holders of the Debt Securities to limit these preferential rights, called "liens," as discussed below under "- Certain Restrictive Covenants - Limitation on Liens on Major Property and United States and Canadian Operating Subsidiaries," or grant an equivalent lien to the holders of the Debt Securities.

Modification and Waiver

There are three types of changes we can make to the indenture and the Debt Securities.

Changes Requiring Your Approval.First, there are changes that cannot be made to your Debt Securities without your specific approval. These include:

9

Changes Not Requiring Approval. Second, changes may be made by us and the trustee without any vote by holders of Debt Securities. These include:

Changes Requiring a Majority Vote. Third, we need a vote by direct holders of Debt Securities owning at least a majority of the principal amount of each series affected by the change to make any other change to the indenture that is not of the type described in the preceding two paragraphs. A majority vote of this kind is also required to obtain a waiver of any past default, except a payment default on principal or interest or concerning a provision of the indenture that cannot be changed without the consent of the direct holder.

Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a Debt Security:

Debt Securities will not be considered outstanding, and therefore will not be eligible to vote, if owned by us or one of our affiliates or if we have deposited or set aside money in trust for their payment or redemption. Debt Securities will also not be eligible to vote if they have been fully defeased as described below under "- Defeasance - Full Defeasance."

We will generally be entitled to set any day as a record date for the purpose of determining the direct holders of outstanding Debt Securities that are entitled to vote or take other action under the indenture. In some circumstances, generally related to a default by us on the Debt Securities, the trustee will be entitled to set a record date for action by holders.

If you are a street name or other indirect holder, you should consult your bank or broker for information on how approval may be granted or denied if we wish to change the indenture or the Debt Securities or request a waiver.

Defeasance

The following discussion of full defeasance and covenant defeasance will apply to your series of Debt Securities only if we choose to have them apply to that series. If we do so choose, we will state that in the applicable prospectus supplement.

Full Defeasance. If there is a change in United States federal tax law as described below, we could legally release ourselves from any payment or other obligations on the Debt Securities of any or all series, called "full defeasance," if we put in place the following arrangements for you to be repaid:

10

In addition, no default must have occurred and be continuing with respect to those Debt Securities at the time the deposit is made (and, with respect only to bankruptcy and similar events, during the 90 days following the deposit), and we have delivered a certificate and a legal opinion to the effect that the deposit does not:

If we ever did accomplish full defeasance, you would have to rely solely on the trust deposit, and could no longer look to us, for repayment on the Debt Securities of the affected series. Conversely, the trust deposit would likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

Covenant Defeasance. Under current United States federal tax law, we can make the same type of deposit described above and be released from many of the covenants in any or all series of Debt Securities. This is called "covenant defeasance." In that event, you would lose the protection of those covenants but would gain the protection of having money and securities set aside in trust to repay the Debt Securities. In order to achieve covenant defeasance, we must do the following:

If we accomplish covenant defeasance, the following provisions, among others, would no longer apply:

If we accomplish covenant defeasance, you can still look to us for repayment of the Debt Securities if there is a shortfall in the trust deposit. Depending on the event causing the default, however, you may not be able to obtain payment of the shortfall.

Redemption

We May Choose to Redeem Your Debt Securities. We may be able to pay off your Debt Securities before their normal maturity. If we have this right with respect to your specific Debt Securities, the right will be described in the applicable prospectus supplement, which will also specify when we can exercise this right and how much we will have to pay in order to redeem your Debt Securities.

If we choose to redeem your Debt Securities, we will mail written notice to you not less than 30 days prior to redemption and not more than 60 days prior to redemption. Also, you may be prevented from exchanging or transferring your Debt Securities when they are subject to redemption, as described above under "- Form, Exchange and Transfers."

11

Default and Related Matters

You will have special rights if an event of default occurs and is not cured.

What is an Event of Default? For each series of Debt Securities the term "event of default" means any of the following:

Remedies if an Event of Default Occurs. In the event of our bankruptcy, insolvency or other similar proceeding, all of the Debt Securities will automatically be due and immediately payable. If a non-bankruptcy event of default has occurred with respect to any series and has not been cured, the trustee or the direct holders of not less than 25% in principal amount of the Debt Securities of the affected series may declare the entire principal amount of all the Debt Securities of that series to be due and immediately payable. This is called a "declaration of acceleration of maturity."

A declaration of acceleration of maturity may be canceled by the direct holders of at least a majority in principal amount of the Debt Securities of the affected series if any other defaults on those Debt Securities have been waived or cured and we pay or deposit with the trustee an amount sufficient to pay the following with respect to the Debt Securities of that series:

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any direct holders unless the holders offer the trustee reasonable protection from expenses and liability, called an "indemnity." If reasonable indemnity is provided, the direct holders of a majority in principal amount of the outstanding Debt Securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority direct holders may also direct the trustee in exercising any trust or power conferred on the trustee under the indenture.

Before you may bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to any Debt Securities of any series, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your Debt Security on or after its due date.

Every year we will certify in a written statement to the trustee that we are in compliance with the indenture and each series of Debt Securities or specify any default that we know about.

12

If you are a street name or other indirect holder, you should consult your bank or broker for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration of maturity.

Conversion or Exchange Rights

Unless otherwise described in the prospectus supplement, the Debt Securities are not convertible or exchangeable for shares of our common stock.

Ranking of Debt Securities

The Debt Securities are not subordinated to any of our other unsecured debt obligations and, therefore, they rank equally with all our other unsecured and unsubordinated indebtedness. The Debt Securities will effectively rank junior to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and to all liabilities of our subsidiaries.

Certain Restrictive Covenants

The indenture contains restrictive covenants that will apply to all Debt Securities issued under it unless we say otherwise in the applicable prospectus supplement, the most significant of which are described below.

Limitation on Liens on Major Property and United States and Canadian Operating Subsidiaries. Some of our property may be subject to a mortgage or other legal mechanism that gives our lenders preferential rights in that property over other lenders, including you and the other direct holders of the Debt Securities, or over our general creditors, if we fail to pay them back. These preferential rights are called "liens." In the indenture, we promise not to create, issue, assume, incur or guarantee any indebtedness for borrowed money that is secured by a mortgage, pledge, lien, security interest or other encumbrance on:

unless we also secure all the Debt Securities that are still outstanding under the indenture equally with the indebtedness being secured. This promise does not restrict our ability to sell or otherwise dispose of our interests in any United States or Canadian operating subsidiary.

These requirements do not apply to liens:

We may also avoid securing the Debt Securities equally with the indebtedness being secured if the amount of the indebtedness being secured plus the value of any sale and lease back transactions, as described below, is 15% or less than the amount of our consolidated total assets minus our consolidated non-interest bearing current liabilities, as reflected on our consolidated balance sheet.

13

If a merger or other transaction would create any liens that are not permitted as described above, we must grant an equivalent lien to the direct holders of the Debt Securities.

Limitation on Sale and Leaseback Transactions. In the indenture, we also promise that we and our United States and Canadian operating subsidiaries will not enter into any sale and leaseback transactions on any of our flourmills, manufacturing or packaging plants or research laboratories located in the United States or Canada owned by us or one of our current or future United States or Canadian operating subsidiaries (referred to in the indenture as "principal properties") unless we satisfy some restrictions. A sale and leaseback transaction involves our sale to a lender or other investor of a property of ours and our leasing back that property from that party for more than three years, or a sale of a property to, and its lease back for three or more years from, another person who borrows the necessary funds from a lender or other investor on the security of the property.

We may enter into a sale and leaseback transaction covering any of our principal properties only if:

We determine the attributable value of a sale and leaseback transaction by choosing the lesser of (1) or (2) below:

14

PLAN OF DISTRIBUTION

We may sell the Debt Securities through underwriters or dealers, directly to one or more purchasers, or through agents. The prospectus supplement will include the names of underwriters, dealers or agents retained. The prospectus supplement also will include the purchase price of the Debt Securities, our proceeds from the sale, any underwriting discounts or commissions and other items constituting underwriters' compensation, and any securities exchanges on which the Debt Securities may be listed.

We may offer the Debt Securities to the public through underwriting syndicates managed by managing underwriters or through underwriters without a syndicate. If underwriters are used, the underwriters will acquire the Debt Securities for their own account. They 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. Unless otherwise indicated in the related prospectus supplement, the obligations of the underwriters to purchase the Debt Securities will be subject to customary conditions precedent and the underwriters will be obligated to purchase all the Debt Securities offered if any of the Debt Securities are purchased. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

Unless the prospectus supplement states otherwise, all Debt Securities will be new issues of Debt Securities with no established trading market. Any underwriters who purchase Debt Securities from us for public offering and sale may make a market in the Debt Securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance concerning the liquidity of the trading market for any Debt Securities.

In order to facilitate the offering of the Debt Securities, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Debt Securities or any other securities, the prices of which may be used to determine payments on the Debt Securities. Specifically, the underwriters may over-allot in connection with any such offering, creating a short position in the Debt Securities for their own accounts. In addition, to cover over-allotments or to stabilize the price of the Debt Securities or of any other securities, the underwriters may bid for, and purchase, the Debt Securities or any other securities in the open market. Finally, in any offering of the Debt Securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the Debt Securities in the offering if the syndicate repurchases previously distributed Debt Securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the Debt Securities above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

Underwriters, dealers and agents that participate in the distribution of the Debt Securities may be underwriters as defined in the Securities Act and any discounts or commissions received by them from us and any profit on the resale of the Debt Securities by them may be treated as underwriting discounts and commissions under the Securities Act.

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 in the ordinary course of their businesses.

One or more firms, referred to as "remarketing firms," may also offer or sell the Debt Securities, if the prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the Debt Securities in accordance with a redemption or repayment pursuant to the terms of the Debt Securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm's compensation. Remarketing firms may be deemed to be underwriters in connection with the Debt Securities they remarket. Remarketing firms may be entitled under agreements that may be entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

We may authorize underwriters, dealers and agents to solicit offers by certain specified institutions to purchase Debt Securities from us at the public offering price set forth in a prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions included in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of the contracts.

Unless indicated in the applicable prospectus supplement, we do not expect to list the Debt Securities on a securities exchange.

VALIDITY OF DEBT SECURITIES

The validity of the Debt Securities will be passed upon for us by Dorsey & Whitney LLP, unless otherwise indicated in the applicable prospectus supplement.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the various expenses expected to be incurred by General Mills, Inc. (the "Company") in connection with the offering described in this registration statement.

Item 15. Indemnification of Directors and Officers.

Under provisions of the Company's By-laws, each person who is or was a director or officer of the Company shall be indemnified by the Company to the fullest extent permitted by Delaware law.

Under Section 145 of the Delaware General Corporation Law, the directors and officers of the Company are entitled, under certain circumstances, to be indemnified by it against all expenses and liabilities incurred by or imposed upon them as a result of suits or actions brought against them as such directors and officers, if they act in good faith and in a manner they reasonably believe to be in or not opposed to the best interests of the Company, and, with respect to any criminal action, have no reasonable cause to believe their conduct was unlawful; except that no indemnification shall be made against expenses in respect of any claim, issue or matter as to which they shall have been adjudged to be liable to the Company, unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, they are fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

The Company maintains directors' and officers' liability insurance that reimburses the Company for certain indemnification liabilities and expenses, and covers directors and officers in certain situations where indemnification is not available from the Company.

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 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 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), (ii) and (iii) 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 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 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 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) 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 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 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 report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 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 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.
