USE OF PROCEEDS

        Unless otherwise specified in a prospectus supplement, the net proceeds from the sale of the securities to which this prospectus relates will be used for general corporate purposes. General corporate purposes may include repayment of debt, repurchases of outstanding shares of common stock, acquisitions, investments, additions to working capital, capital expenditures and advances to or investments in our subsidiaries. Net proceeds may be temporarily invested prior to use.

DESCRIPTION OF THE DEBT SECURITIES

        This section describes the general terms and provisions of any debt securities that we may offer in the future. A prospectus supplement relating to a particular series of debt securities will describe the material terms of that particular series and to the extent to which the general terms and provisions contained herein apply to that particular series.

GENERAL

        The debt securities will either be our senior debt securities or our subordinated debt securities. We expect to issue the debt securities under one or more separate indentures between us and J.P. Morgan Trust Company, National Association (formerly known as Chase Manhattan Bank and Trust Company, National Association), as trustee. Senior debt securities will be issued under a senior indenture and subordinated debt securities will be issued under a subordinated indenture. Together, the senior indenture and subordinated indenture are called indentures. For additional information, you should look at the applicable form of indenture that is filed as an exhibit to our registration statement on Form S-3 (file number 333-30786), dated March 17, 2000. Each of the indentures is incorporated by reference into this prospectus. In this description of the debt securities, the words "we," "us" or "our" refer only to Hewlett-Packard Company and not to any of our subsidiaries.

        Debt securities may be issued in separate series without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series. We are not limited as to the amount of debt securities we may issue under the indentures. Unless otherwise provided in a prospectus supplement, a series of debt securities may be reopened for issuance of additional debt securities of such series.

TERMS OF A PARTICULAR SERIES

        Each prospectus supplement relating to a particular series of debt securities will include specific information relating to the offering. This information will include some or all of the following terms of the debt securities of the series:

•

whether the debt securities are senior or subordinated;



•

the offering price;



•

the title;



•

any limit on the aggregate principal amount;



•

the person who shall be entitled to receive interest, if other than the record holder on the record date;



•

the date the principal will be payable;



•

the interest rate, if any, the date interest will accrue, the interest payment dates and the regular record dates;



•

the interest rate, if any, payable on overdue installments of principal, premium or interest;

2

---

•

the place where payments shall be made;



•

any mandatory or optional redemption provisions;



•

if applicable, the method for determining how principal, premium, if any, or interest will be calculated by reference to an index or formula;



•

if other than U.S. currency, the currency or currency units in which principal, premium, if any, or interest will be payable and whether we or the holder may elect payment to be made in a different currency;



•

the portion of the principal amount that will be payable upon acceleration of stated maturity, if other than the entire principal amount;



•

if the principal amount payable at stated maturity will not be determinable as of any date prior to stated maturity, that the amount payable will be deemed to be the principal amount;



•

any defeasance provisions if different from those described below under "Satisfaction and Discharge—Defeasance;"



•

any conversion or exchange provisions;



•

whether the debt securities will be issuable in the form of a global security;



•

any subordination provisions if different from those described below under "Subordinated Debt Securities;"



•

any paying agents, authenticating agents or security registrars;



•

any guarantees on the debt securities;



•

any security for any of the debt securities;



•

any deletions of, or changes or additions to, the events of default or covenants; and



•

any other specific terms of such debt securities.

        Unless otherwise specified in the prospectus supplement:

•

the debt securities will be registered debt securities; and



•

registered debt securities denominated in U.S. dollars will be issued in denominations of $1,000 or multiples of $1,000.

        Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at time of issuance is below market rates.

EXCHANGE AND TRANSFER

        Debt securities may be transferred or exchanged at the office of the security registrar or at the office of any transfer agent designated by us. We will not impose a service charge for any transfer or exchange, but we may require holders to pay any tax or other governmental charges associated with any transfer or exchange.

        In the event of any potential redemption of debt securities of any series in part, we will not be required to:

•

issue, register the transfer of, or exchange any debt security of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption and ending at the close of business on the day of the mailing; or

3

---

•

register the transfer of or exchange any debt security of that series selected for redemption, in whole or in part, except the unredeemed portion being redeemed in part.

        We have initially appointed the trustee as the security registrar. Any transfer agent, in addition to the security registrar, initially designated by us will be named in the prospectus supplement. We may designate additional transfer agents, change transfer agents or change the office of the transfer agent, change any security registrar or act as security registrar. However, we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

GLOBAL SECURITIES

        The debt securities of any series may be represented, in whole or in part by one or more global securities. Each global security will:

•

be registered in the name of a depositary that we will identify in a prospectus supplement;



•

be deposited with the depositary or nominee or custodian; and



•

bear any required legends.

        No global security may be exchanged in whole or in part for debt securities registered in the name of any person other than the depositary or any nominee, referred to as certificated debt securities, unless:

•

the depositary has notified us that it is unwilling or unable to continue as depositary or has ceased to be qualified to act as depositary;



•

an event of default is continuing; or



•

any other circumstances described in a prospectus supplement have occurred permitting the issuance of certificated debt securities.

        As long as the depositary, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner and holder of the debt securities represented by the global security for all purposes under the indenture. Except in the above limited circumstances, owners of beneficial interests in a global security will not be:

•

entitled to have the debt securities registered in their names;



•

entitled to physical delivery of certificated debt securities; and



•

considered to be holders of those debt securities under the indenture.

        Payments on a global security will be made to the depositary or its nominee as the holder of the global security. Some jurisdictions have laws that require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

        Institutions that have accounts with the depositary or its nominee are referred to as "participants." Ownership of beneficial interests in a global security will be limited to participants and to persons that may hold beneficial interests through participants. The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants.

        Ownership of beneficial interests in a global security will be shown on and effected through records maintained by the depositary, with respect to participants' interests, or any participant, with respect to interests of persons held by participants on their behalf.

4

---

        Payments, transfers and exchanges relating to beneficial interests in a global security will be subject to policies and procedures of the depositary. The depositary policies and procedures may change from time to time. Neither the trustee nor we will have any responsibility or liability for the depositary's or any participant's records with respect to beneficial interests in a global security.

PAYMENT AND PAYING AGENTS

        Unless otherwise indicated in the prospectus supplement:

•

Payment of interest on a debt security on any interest payment date will be made to the person in whose name the debt security is registered at the close of business on the regular record date; and



•

Payment on debt securities of a particular series will be payable at the office of a paying agent or paying agents designated by us.

        At our option, however, we may pay interest by mailing a check to the record holder.

        The corporate trust office of the trustee will initially be designated as our sole paying agent. We may also name any other paying agents in the prospectus supplement. We may designate additional paying agents, change paying agents or change the office of any paying agent. However, we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

        All monies paid by us to a paying agent for payment on any debt security which remain unclaimed for a period ending the earlier of 10 business days prior to the date the money would be turned over to the state, or at the end of two years after the payment was due, will be repaid to us. Thereafter, the holder may look only to us for such payment.

CONSOLIDATION, MERGER AND SALE OF ASSETS

        We may not consolidate with or merge into any other person, in a transaction in which we are not the surviving corporation, or convey, transfer or lease our properties and assets substantially as an entirety to, any person, unless:

•

the successor, if any, is a U.S. corporation, limited liability company, partnership, trust or other entity;



•

the successor assumes our obligations on the debt securities and under the indentures;



•

immediately after giving effect to the transaction, no default or event of default shall have occurred and be continuing; and



•

certain other conditions are met.

EVENTS OF DEFAULT

        Each indenture defines an event of default with respect to any series of debt securities as one or more of the following events:

        (1)   failure to pay principal of or any premium on any debt security of that series when due;

        (2)   failure to pay any interest on any debt security of that series for 30 days when due;

        (3)   failure to make any sinking fund payment for 30 days when due;

        (4)   failure to perform any other covenant in the indenture if that failure continues for 90 days after we are given the notice required in the indenture;

5

---

        (5)   our bankruptcy, insolvency or reorganization; and

        (6)   any other event of default specified in the prospectus supplement.

        An event of default of one series of debt securities is not necessarily an event of default for any other series of debt securities.

        If an event of default, other than an event of default described in clause (5) above, shall occur and be continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding securities of that series may declare the principal amount of the debt securities of that series to be due and payable immediately. If an event of default described in clause (5) above shall occur, the principal amount of all the debt securities of that series will automatically become immediately due and payable. Any payment by us on the subordinated debt securities following any acceleration will be subject to the subordination provisions described below under "Subordinated Debt Securities."

        After acceleration, the holders of a majority in aggregate principal amount of the outstanding securities of that series, under certain circumstances, may rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, or other specified amount, have been cured or waived.

        Other than the duty to act with the required care during an event of default, the trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders shall have offered to the trustee reasonable indemnity. Generally, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will 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.

        A holder will not have any right to institute any proceeding under the indentures, or for the appointment of a receiver or a trustee, or for any other remedy under the indentures, unless:

        (1)   the holder has previously given to the trustee written notice of a continuing event of default with respect to the debt securities of that series;

        (2)   the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made a written request and have offered reasonable indemnity to the trustee to institute the proceeding; and

        (3)   the trustee has failed to institute the proceeding and has not received direction inconsistent with the original request from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series within 60 days after the original request.

        Holders may, however, sue to enforce the payment of principal, premium or interest on any series of debt securities on or after the due date without following the procedures listed in (1) through (3) above.

        We will furnish the trustee an annual statement by our officers as to whether or not we are in default in the performance of the indenture and, if so, specifying all known defaults.

MODIFICATION AND WAIVER

        We and the trustee may make modifications and amendments to the indentures with the consent of the holders of a majority in aggregate principal amount of the outstanding securities of each series affected by the modification or amendment. We may also make modifications and amendments to the

6

---

indentures for the benefit of the holders, without their consent, for certain purposes including, but not limited to:

•

providing for our successor to assume the covenants under the indenture;



•

adding covenants or events of default;



•

making certain changes to facilitate the issuance of the securities;



•

securing the securities;



•

providing for a successor trustee;



•

curing any ambiguities or inconsistencies;



•

permitting or facilitating the defeasance and discharge of the securities; and



•

other changes specified in the indenture.

        However, neither we nor the trustee may make any modification or amendment without the consent of the holder of each outstanding security of that series affected by the modification or amendment if such modification or amendment would:

•

change the stated maturity of any debt security;



•

reduce the principal, premium, if any, or interest on any debt security;



•

reduce the principal of an original issue discount security or any other debt security payable on acceleration of maturity;



•

change the place of payment or the currency in which any debt security is payable;



•

impair the right to sue for any payment after the stated maturity or redemption date;



•

if subordinated debt securities, modify the subordination provisions in a materially adverse manner to the holders of subordinated debt securities;



•

adversely affect the right to convert any debt security; or



•

change the provisions in the indenture that relate to modifying or amending the indenture.

SATISFACTION AND DISCHARGE; DEFEASANCE

        We may be discharged from our obligations on the debt securities of any series if we deposit enough money with the trustee to pay all the principal, interest and any premium due to the stated maturity date or redemption date of the debt securities.

        Each indenture contains a provision that permits us to elect either or both of the following:

•

to be discharged from all of our obligations, subject to limited exceptions, with respect to any series of debt securities then outstanding; and



•

to be released from our obligations under the following covenants and from the consequences of an event of default resulting from a breach of these and a number of other covenants:

        (1)   the limitations on sale and lease-back transactions under the senior indenture;

        (2)   the limitations on liens under the senior indenture;

        (3)   covenants as to payment of taxes and maintenance of properties; and

        (4)   the subordination provisions under the subordinated indenture.

7

---

        To make either of the above elections, we must deposit in trust with the trustee enough money to pay in full the principal, interest and premium on the debt securities. This amount may be made in cash and/or U.S. government obligations. As a condition to either of the above elections, we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of the action.

        If any of the above events occur, the holders of the debt securities of the series will not be entitled to the benefits of the indenture, except for registration of transfer and exchange of debt securities, replacement of lost, stolen or mutilated debt securities and, if applicable, conversion and exchange of debt securities.

NOTICES

        Notices to holders will be given by mail to the addresses of the holders in the security register.

GOVERNING LAW

        The indentures and the debt securities will be governed by, and construed under, the laws of the State of New York, without regard to conflicts of laws principles.

REGARDING THE TRUSTEE

        The indentures limit the right of the trustee, if it becomes our creditor, to obtain payment of claims or secure its claims.

        The trustee is permitted to engage in certain other transactions. If the trustee acquires any conflicting interest, however, and there is a default under the debt securities of any series for which they are trustee, the trustee must eliminate the conflict or resign. J.P. Morgan Trust Company, National Association is also our depositary and affiliates of J.P. Morgan Trust Company, National Association, have performed and continue to perform other services for us in the normal course of business.

SENIOR DEBT SECURITIES

        The senior debt securities will be unsecured, unless we elect otherwise, and will rank equally with all of our other unsecured and non-subordinated senior debt.

COVENANTS IN THE SENIOR INDENTURE

        LIMITATIONS ON LIENS.    Neither we nor any restricted subsidiary will issue, incur, create, assume or guarantee any secured debt without securing the senior debt securities equally and ratably with or prior to that secured debt unless the total amount of all secured debt with which the senior debt securities are not at least equally and ratably secured would not exceed the greater of $500 million or 10% of our consolidated net tangible assets.

        LIMITATIONS ON SALE AND LEASE-BACK TRANSACTIONS.    Subject to the last paragraph of this section, neither we nor any restricted subsidiary will enter into any lease with a term longer than three years covering any of our principal property or any restricted subsidiary that is sold to any other person in connection with that lease unless either:

        (1)   we or any restricted subsidiary would be entitled to incur indebtedness secured by a mortgage on the principal property involved in such transaction at least equal in amount to the attributable debt with respect to the lease, without equally and ratably securing the senior debt securities, pursuant to "Limitation on Liens" described above; or

8

---

        (2)   an amount equal to the greater of the following amounts is applied within 180 days of such sale to the retirement of our or any restricted subsidiary's long-term debt or the purchase or development of comparable property:

•

the net proceeds from the sale; or



•

the attributable debt with respect to the sale and lease-back transaction.

        However, either we or our restricted subsidiaries would be able to enter into a sale and lease-back transaction without being required to apply the net proceeds as required by (2) above if the sum of the following amounts would not exceed the greater of $500 million or 10% of our consolidated net tangible assets:

•

the total amount of the sale and lease-back transactions; and



•

the total amount of secured debt.

DEFINITIONS RELATING TO THE SENIOR DEBT SECURITIES

SUBORDINATED DEBT SECURITIES

        The subordinated debt securities are subordinated in right of payment to the prior payment in full of all senior debt, including any senior debt securities. In the event of our dissolution, winding up, liquidation or reorganization, the holders of senior debt shall be entitled to receive payment in full

10

---

before holders of subordinated debt securities shall be entitled to receive any payment or distribution on any subordinated debt securities.

        In the event of insolvency, upon any distribution of our assets:

•

holders of subordinated debt securities are required to pay over their share of such distribution to the trustee in bankruptcy, receiver or other person distributing our assets to pay all senior debt remaining to the extent necessary to pay all holders of senior debt in full; and



•

our unsecured creditors who are not holders of subordinated debt securities or holders of senior debt may recover less, ratably, than holders of senior debt and may recover more, ratably, than the holders of subordinated debt securities.

DEFINITIONS RELATING TO SUBORDINATED DEBT SECURITIES

        "senior debt" means the principal, premium, if any, and unpaid interest on:

•

our indebtedness for borrowed money;



•

our obligations evidenced by bonds, debentures, notes or similar instruments;



•

our obligations under any interest rate swaps, caps, collars, options, and similar arrangements;



•

our obligations under any foreign exchange contract, currency swap contract, futures contract, currency option contract, or other foreign currency hedge arrangements;



•

our obligations under any credit swaps, caps, floors, collars and similar arrangements;



•

indebtedness incurred, assumed or guaranteed by us in connection with the acquisition by us or any of our subsidiaries of any business, properties or assets, except purchase-money indebtedness classified as accounts payable under generally accepted accounting principles;



•

our obligations as lessee under leases required to be capitalized on the balance sheet in conformity with generally accepted accounting principles;



•

all obligations under any lease or related document, including a purchase agreement, in connection with the lease of real property which provides that we are contractually obligated to purchase or cause a third party to purchase the leased property and thereby guarantee a minimum residual value of the leased property to the lessor and our obligations under such lease or related document to purchase or to cause a third party to purchase such leased property;



•

our reimbursement obligations in respect of letters of credit relating to indebtedness or our other obligations that qualify as indebtedness or obligations of the kind referred to above; and



•

our obligations under direct or indirect guaranties in respect of, and obligations to purchase or otherwise acquire, or otherwise to assure a creditor against loss in respect of, indebtedness or obligations of others of the kinds referred to above.

        However, senior debt shall not include (i) any indebtedness or obligation that provides that such indebtedness or obligation is not superior in right of payment to the subordinated debt securities or provides that such indebtedness is subordinate to our other indebtedness and obligations and (ii) indebtedness related to our Liquid Yield Option™ Notes due 2017.

        The subordinated debt securities are effectively subordinated to all existing and future liabilities of our subsidiaries. Any right we have to participate in any distribution of the assets of any of our

11

---

subsidiaries upon their liquidation, reorganization or insolvency, and the consequent right of holders of senior debt securities to participate in those assets, will be subject to the claims of the creditors of such subsidiary. In addition, any claim we may have as a creditor would still be subordinate to any security interest in the assets of such subsidiary and any indebtedness of such subsidiary senior to that held by us.

DESCRIPTION OF COMMON STOCK

        Our certificate of incorporation authorizes us to issue up to 9,600,000,000 shares of common stock, par value $0.01 per share. As of May 12, 2006 there were approximately 2,802,381,088 shares of common stock outstanding.

        The holders of common stock as of the applicable record date are entitled to one vote per share on all matters to be voted upon by the stockholders. The holders of common stock have cumulative voting rights for the election of our directors in accordance with our bylaws and Delaware law. Subject to preferences applicable to any outstanding preferred stock, the holders of common stock are entitled to receive ratably such dividends as may be declared from time to time by the board of directors out of funds legally available for distribution, and, in the event of our liquidation, dissolution or winding up, the holders of common stock are entitled to share in all assets remaining after payment of liabilities. The common stock has no preemptive or conversion rights and is not subject to further calls or assessments by us. There are no redemption or sinking fund provisions available to the common stock. The common stock currently outstanding is validly issued, fully paid and nonassessable.

        The transfer agent and registrar for the common stock is Computershare Investor Services.

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW

        We are subject to the provisions of Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder, unless:

        (1)   prior to such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

        (2)   upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned:

•

by persons who are directors and also officers; and



•

by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

        (3)   at or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66²/3% of the outstanding voting stock that is not owned by the interested stockholder.

        Section 203 defines "business combination" to include:

        (1)   any merger or consolidation involving the corporation and the interested stockholder;

        (2)   any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

12

---

        (3)   subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

        (4)   any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

        (5)   the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

        In general, Section 203 defines an "interested stockholder" as any person who or which beneficially owns 15% or more of the outstanding voting stock of the corporation or any person affiliated with or controlling or controlled by the corporation that was the owner of 15% or more of the outstanding voting stock of the corporation at any time within the three-year period immediately prior to the date of determination if such person is an interested stockholder.

        The existence of this provision would be expected to have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, including discouraging attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

DESCRIPTION OF PREFERRED STOCK

GENERAL

        Our certificate of incorporation authorizes us to issue up to 300,000,000 shares of preferred stock, par value $0.01 per share, in one or more series. As of the date of this prospectus, we did not have any outstanding shares of preferred stock or options to purchase preferred stock. Our board of directors, however, has the authority without stockholder consent, subject to certain limitations imposed by law or our bylaws, to issue one or more series of preferred stock at any time. The certificate of designation relating to each series will fix the rights, preferences and restrictions of the preferred stock of each series. A prospectus supplement relating to each such series will specify the terms of the preferred stock as determined by our board of directors, including the following:

•

the number of shares in any series;



•

the designation for any series by number, letter or title that shall distinguish the series from any other series of preferred stock;



•

the dividend rate and whether dividends on that series of preferred stock will be cumulative, noncumulative or partially cumulative;



•

the voting rights of that series of preferred stock, if any;



•

any conversion provisions applicable to that series of preferred stock;



•

any redemption or sinking fund provisions applicable to that series of preferred stock including whether there is any restriction on the repurchase or redemption of the preferred stock while there is any arrearage in the payment of dividends or sinking fund installments;



•

the liquidation preference per share of that series of preferred stock, if any; and



•

the terms of any other preferences or rights, if any, applicable to that series of preferred stock.

        We will describe the specific terms of a particular series of preferred stock in the prospectus supplement relating to that series. The description of preferred stock above and the description of the terms of a particular series of preferred stock in the related prospectus supplement will not be complete. You should refer to the certificate of designation for complete information. The prospectus

13

---

supplement will also contain a description of certain U.S. federal income tax consequences relating to the preferred stock.

        Although it has no present intention to do so, our board of directors, without stockholder approval, may issue preferred stock with voting and conversion rights, which could adversely affect the voting power of the holders of common stock. If we issue preferred stock, it may have the effect of delaying, deferring or preventing a change of control.

DESCRIPTION OF THE DEPOSITARY SHARES

        At our option, we may elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. If we do, we will issue to the public receipts for depositary shares and each of these depositary shares will represent a fraction, to be set forth in the prospectus supplement, of a share of a particular series of preferred stock. Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of preferred stock underlying that depositary share, to all rights and preferences of the preferred stock underlying that depositary share. Those rights include dividend, voting, redemption and liquidation rights.

        The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

        Depositary receipts issued pursuant to the depositary agreement will evidence the depositary shares. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

        The summary of terms of the depositary shares contained in this prospectus is not complete. You should refer to the forms of the deposit agreement, our certificate of incorporation and the certificate of amendment for the applicable series of preferred stock that are, or will be, filed with the SEC.

DIVIDENDS

        The depositary will distribute all cash dividends or other cash distributions received in respect of the series of preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date, which will be the same date as the record date for the preferred stock.

        In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net proceeds to the holders.

LIQUIDATION PREFERENCE

        In the event of our voluntary or involuntary liquidation, dissolution or winding up, the holders of each depositary share will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

REDEMPTION

        If a series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the

14

---

redemption, in whole or in part, of preferred stock held by the depositary. Whenever we redeem any preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from us and not fewer than 35 nor more than 60 days, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of the preferred stock and the depositary shares.

VOTING

        Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying the preferred stock. Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock underlying that holder's depositary shares. The record date for the depositary will be the same date as the record date for the preferred stock. The depositary will try, as far as practicable, to vote the preferred stock underlying the depositary shares in accordance with such instructions, and we will agree to take all action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote the preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.

WITHDRAWAL OF PREFERRED STOCK

        Owners of depositary shares are entitled, upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, to receive the number of whole shares of preferred stock underlying the depositary shares. Partial shares of preferred stock will not be issued. Holders of preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for the preferred stock.

AMENDMENT AND TERMINATION OF DEPOSIT AGREEMENT

        The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended at any time and from time to time by agreement between us and the depositary. However, any amendment which materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by the depositary or us only if:

•

all outstanding depositary shares have been redeemed; or



•

there has been a final distribution in respect of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.

CHARGES OF DEPOSITARY

        We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will also pay charges of the depositary in connection with the initial deposit of the preferred stock and the initial issuance of the depositary shares, any redemption of the preferred stock and all withdrawals of preferred stock by owners of depositary shares. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement to be for their accounts. The depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt if the charges are not paid.

15

---

MISCELLANEOUS

        The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

        Neither the depositary nor we will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing our respective obligations under the deposit agreement. Our obligations and those of the depositary will be limited to performance in good faith of our respective duties under the deposit agreement. Neither the depositary nor we will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely on written advice of counsel or accountants, on information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information and on documents believed to be genuine and to have been signed or presented by the proper party or parties.

RESIGNATION AND REMOVAL OF DEPOSITARY

        The depositary may resign at any time by delivering a notice to us of its election to do so. We may remove the depositary at any time. Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice for resignation or removal and must be a bank or trust company having its principal office in the United States of America and having a combined capital and surplus of at least $150,000,000.

FEDERAL INCOME TAX CONSEQUENCES

        Owners of the depositary shares will be treated for United States federal income tax purposes as if they were owners of the preferred stock underlying the depositary shares. As a result, owners will be entitled to take into account for United States federal income tax purposes, income and deductions to which they would be entitled if they were holders of such preferred stock. No gain or loss will be recognized for United States federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares. The tax basis of each share of preferred stock to an exchanging owner of depositary shares will be, upon such exchange, the same as the aggregate tax basis of the depositary shares exchanged. The holding period for preferred stock in the hands of an exchanging owner of depositary shares will include the period during which such person owned such depositary shares.

DESCRIPTION OF THE WARRANTS

GENERAL

        We may issue warrants for the purchase of debt securities, preferred stock or common stock. Warrants may be issued independently or together with debt securities, preferred stock or common stock and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

        This summary of certain provisions of the warrants is not complete. For the complete terms of the warrant agreement, you should refer to the provisions of the warrant agreement that will be filed with the SEC in connection with the offering of warrants.

PLAN OF DISTRIBUTION

        We may sell the securities separately or together:

•

through one or more underwriters or dealers in a public offering and sale by them,



•

directly to investors, or



•

through agents.

        We may sell the securities from time to time:

•

in one or more transactions at a fixed price or prices which may be changed from time to time,



•

at market prices prevailing at the times of sale,



•

at prices related to such prevailing market prices, or



•

at negotiated prices.

        We will describe the method of distribution of the securities in the prospectus supplement.

        We may determine the price or other terms of the securities offered under this prospectus by use of an electronic auction. We will describe how any auction will determine the price or any other terms, how potential investors may participate in the auction and the nature of the underwriters' obligations in the related supplement to this prospectus.

        Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us or our purchasers, as their agents in connection with the sale of securities. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act of 1933, as amended (the "Securities Act"). As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. The prospectus supplement will identify any such underwriter, dealer or agent and describe any compensation received by them from us. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

        Underwriters, dealers and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments

18

---

made by the underwriters, dealers or agents, under agreements between us and the underwriters, dealers and agents.

        We may grant underwriters who participate in the distribution of securities an option to purchase additional securities to cover over-allotments, if any, in connection with the distribution.

        Unless otherwise indicated in the applicable prospectus supplement, all securities offered by this prospectus, other than our common stock, will be new issues of securities with no established trading market. Underwriters involved in the public offering and sale of securities may make a market in the securities but are not required to do so and may discontinue market-making activity at any time. No assurance can be given as to the liquidity of the trading market for any securities.

        Underwriters or agents and their associates may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

        Any underwriter may engage in over-allotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Over-allotment involves sales in excess of the offering size, which creates a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of those activities at any time.

LEGAL MATTERS

        Charles N. Charnas, Vice President, Deputy General Counsel and Assistant Secretary of HP or another lawyer within HP's Legal Department will provide opinions regarding the authorization and validity of the securities and, to the extent that authorization and validity are governed by New York law, such internal counsel may rely on the opinion of Wilson Sonsini Goodrich & Rosati Professional Corporation. Mr. Charnas and the other lawyers in HP's Legal Department are paid salaries by HP, are participants in various employee benefit plans offered by HP to its employees generally and own and have options to purchase shares of HP common stock. Any underwriters will also be advised about the validity of the securities and other legal matters by their own counsel, which will be named in the prospectus supplement.

Item 15.    Indemnification of directors and officers.

        Section 145 of the General Corporation Law of the State of Delaware authorizes a court to award or a corporation's board of directors to grant indemnification to directors and officers in terms that are sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933.

        Our certificate of incorporation contains a provision eliminating the personal liability of our directors to HP or its stockholders for breach of fiduciary duty as a director to the fullest extent permitted by applicable law.

        Our bylaws provide for the indemnification of our directors and officers to the maximum extent permitted by Delaware law. Our bylaws also provide:

          (i)  that we are authorized to enter into individual indemnification contracts with our directors and officers to the fullest extent not prohibited by Delaware law, and

         (ii)  that we shall not be required to indemnify any director or officer if (a) the director or officer has not met the standard of conduct which makes indemnification permissible under Delaware law, or (b) the proceeding for which indemnification is sought was initiated by such director or officer and such proceeding was not authorized by the board of directors.

        HP maintains liability insurance for our directors and officers. HP has also agreed to indemnify certain officers against certain claims by their former employers as a result of their employment by HP.

        In addition, our bylaws give us the power to indemnify our employees and agents to the maximum extent permitted by Delaware law.

        The underwriting agreements that may be entered into between us and the underwriters may contain certain provisions regarding indemnification of our officers and directors by the underwriters.

To be filed as an exhibit to a Current Report on Form 8-K and incorporated by reference or by post-effective amendment.

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; (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 clauses (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:

        (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 Registration Statement or made in any such document immediately prior to such effective date; and

        (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-3

---

         (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, each filing of Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act 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 provisions described under Item 15 above, 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 that:

        (1)   For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430(a) and contained in a form of prospectus filed by the registrant pursuant to Rule 420(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

        (2)   For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.
