HEWLETT-PACKARD COMPANY

OFFICERS’ CERTIFICATE PURSUANT TO

SECTION 301 OF THE INDENTURE

September 19, 2011

We, Paul T. Porrini and John N. McMullen, do hereby certify that we are the duly appointed Vice President, Deputy General Counsel and Assistant Secretary and Senior Vice President and Treasurer, respectively, of Hewlett-Packard Company, a Delaware corporation (the “Company”). We further certify, pursuant to the consent of the Debt Subcommittee of the Board of Directors of the Company adopted as of September 13, 2011 (a copy of which is attached hereto as Exhibit A), that pursuant to Section 301 of the Indenture, dated as of June 1, 2000 (the “Indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor to The Bank of New York Trust Company, N.A ., the successor to J.P. Morgan Trust Company, National Association, the successor to Chase Manhattan Bank and Trust Company, National Association), as trustee, three series of debt securities of the Company are hereby established, with the following terms and provisions:

1. The titles of such series of Securities shall be the “Floating Rate Global Notes due September 19, 2014” (the “Floating Rate Global Notes”), the “2.350% Global Notes due March 15, 2015” (the “2015 Global Notes”), the “3.000% Global Notes due September 15, 2016” (the “2016 Global Notes”), the “4.375% Global Notes due September 15, 2021” (the “2021 Global Notes”) and the “6.000% Global Notes due June 1, 2041” (the “2041 Global Notes”, together with the 2015 Global Notes, the 2016 Global Notes and the 2021 Global Notes, the “Fixed Rate Global Notes”, and the Fixed Rate Global Notes and the Floating Rate Global Notes, collectively, the “Global Notes”) (copies of which are attached hereto as Exhibits B-1, B-2, B-3, B-4, and B-5, respectively).

2. The aggregate principal amount of the Global Notes that may be authenticated and delivered under the Indenture shall be $350,000,000 aggregate principal amount of the Floating Rate Global Notes, $750,000,000 aggregate principal amount of the 2015 Global Notes, $1,300,000,000 aggregate principal amount of the 2016 Global Notes, $1,000,000,000 aggregate principal amount of the 2021 Global Notes and $1,200,000,000 aggregate principal amount of the 2041 Global Notes (except for Global Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Global Notes pursuant to Sections 304, 305, 306, 906 and 1107 of the Indenture, and except for any Global Notes which, pursuant to Section 303 of the Indenture, shall be deemed never to have been authenticated and delivered thereunder).

3. The prices at which the Global Notes shall be issued to the public are: 100% for the Floating Rate Global Notes; 99.977% for the 2015 Global Notes; 99.784% for the 2016 Global Notes; 99.816% for the 2021 Global Notes; and 99.863% for the 2041 Global Notes.

4. Interest on the Global Notes shall be payable to the Persons in whose names the Global Notes (or one or more Predecessor Securities) are registered at the close of business on the Regular Record Date for such interest.

5. The Stated Maturity of the Floating Rate Global Notes on which the principal thereof is due and payable is September 19, 2014 (if such date is not a Business Day, payment of principal, premium, if any, and interest for the Securities will be paid on the next Business Day; provided, however, that no interest on that payment will accrue from and after September 19, 2014). The Stated Maturity of the 2015 Global Notes on which the principal thereof is due and payable is March 15, 2015 (if such date is not a Business Day, payment of principal, premium, if any, and interest for the Securities will be paid on the next Business Day; provided, however, that no interest on that payment will accrue from and after March 15, 2015). The Stated Maturity of the 2016 Global Notes on which the principal thereof is due and payable is September 15, 2016 (if such date is not a Business Day, payment of principal, premium, if any, and interest for the Securities will be paid on the next Business Day; provided, however, that no interest on that payment will accrue from and after September 15, 2016). The Stated Maturity of the 2021 Global Notes on which the principal thereof is due and payable is September 15, 2021 (if such date is not a Business Day, payment of principal, premium, if any, and interest for the Securities will be paid on the next Business Day; provided, however, that no interest on that payment will accrue from and after September 15, 2021). The Stated Maturity of the 2041 Global Notes on which the principal thereof is due and payable is September 15, 2041 (if such date is not a Business Day, payment of principal, premium, if any, and interest for the Securities will be paid on the next Business Day; provided, however, that no interest on that payment will accrue from and after September 15, 2041).

6. The Floating Rate Global Notes will bear interest for each interest period at a rate determined by the calculation agent. The calculation agent is The Bank of New York Mellon Trust Company, N.A. until such time as the Company appoints a successor calculation agent. The interest rate on the Floating Rate Global Notes for a particular interest period will be a per annum rate equal to three-month USD LIBOR as determined on the interest determination date plus 1.55%. The interest determination date for an interest period will be the second London business day preceding the first day of such interest period. Promptly upon determination, the calculation agent will inform the Trustee and the Company of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the calculation agent shall be binding and conclusive on the holders of the Floating Rate Global Notes, the Trustee and the Company. A London business day is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

Interest on the Floating Rate Global Notes will be paid to but excluding the relevant Interest Payment Date. Interest payments on the 2013 Floating Rate Global Notes will be made quarterly in arrears on March 19, June 19, September 19 and December 19 of each year, beginning on December 19, 2011, to the person in whose name the Floating Rate Global Notes are registered at the close of business on the Business Day immediately preceding the Interest Payment Date. Interest on the Floating Rate Global Notes will accrue from and including September 19, 2011, to but excluding the

-2-

first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but excluding the next Interest Payment Date or date of Maturity, as the case may be. Each of these periods is referred to as an “interest period.” The amount of accrued interest that the Company will pay for any interest period shall be calculated by multiplying the face amount of the Floating Rate Global Notes then outstanding by an accrued interest factor. This accrued interest factor is computed by adding the interest factor calculated for each day from September 19, 2011, or from the latest date interest was paid to the date for which accrued interest is being calculated. The interest factor for each day is computed by dividing the interest rate applicable to that date by 360. If an Interest Payment Date for the Floating Rate Global Notes falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day.

On any interest determination date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least $1,000,000, as such rate appears on “Reuters Page LIBOR01” at approximately 11:00 a.m., London time, on such interest determination date. If on an interest determination date, such rate does not appear on the “Reuters Page LIBOR 01” as of 11:00 a.m., London time, or if the “Reuters Page LIBOR01” is not available on such date, the calculation agent will obtain such rate from Bloomberg L.P.’s page “BBAM.”

If no offered rate appears on “Reuters Page LIBOR01” or Bloomberg L.P.’s page “BBAM” on an interest determination date at approximately 11:00 a.m., London time, then the calculation agent (after consultation with the Company) will select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the calculation agent will select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by them at approximately 11:00 a.m., New York City time, on the interest determination date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable interest period in an amount of at least $1,000,000 that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next interest period will be set equal to the rate of LIBOR for the then current interest period.

Upon request from any holder of Floating Rate Global Notes, the calculation agent will provide the interest rate in effect for the Floating Rate Global Notes for the current interest period and, if it has been determined, the interest rate to be in effect for the next interest period.

-3-

All percentages resulting from any calculation of the interest rate on the Floating Rate Global Notes will be rounded to the nearest one hundred-thousandth of a percentage point with five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculation on the Floating Rate Global Notes will be rounded to the nearest cent (with one-half cent being rounded upward). Each calculation of the interest rate on the Floating Rate Global Notes by the calculation agent will (in the absence of manifest error) be final and binding on the Holders and the Company.

The interest rate on the Floating Rate Global Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by Unites States law of general application.

7. The 2015 Global Notes will bear interest at the rate of 2.350% per year. Interest on the 2015 Global Notes will be paid semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2012, to the holders of record of the 2015 Global Notes at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the related Interest Payment Date. Interest on the 2015 Global Notes will accrue from and including September 19, 2011, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but excluding the next Interest Payment Date or Maturity date, as the case may be. Interest on the 2015 Global Notes will be paid on the basis of a 360-day year comprised of twelve 30-day months. If an Interest Payment Date on the 2015 Global Notes falls on a date that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day.

8. The 2016 Global Notes will bear interest at the rate of 3.000% per year. We will make interest payments on the 2016 Global Notes semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2012, to the holders of record of the 2016 Global Notes at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the related Interest Payment Date. Interest on the 2016 Global Notes will accrue from and including September 19, 2011, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but excluding the next Interest Payment Date or Maturity date, as the case may be. Interest on the 2016 Global Notes will be paid on the basis of a 360-day year comprised of twelve 30-day months. If an Interest Payment Date on the 2016 Global Notes falls on a date that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day.

9. The 2021 Global Notes will bear interest at the rate of 4.375% per year. We will make interest payments on the 2021 Global Notes semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2012, to the holders of record of the 2021 Global Notes at the close of business on the fifteenth day (whether or not a Business Day)

-4-

immediately preceding the related Interest Payment Date. Interest on the 2021 Global Notes will accrue from and including September 19, 2011, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but excluding the next Interest Payment Date or Maturity date, as the case may be. Interest on the 2021 Global Notes will be paid on the basis of a 360-day year comprised of twelve 30-day months. If an Interest Payment Date on the 2021 Global Notes falls on a date that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day.

10. The 2041 Global Notes will bear interest at the rate of 6.000% per year. We will make interest payments on the 2041 Global Notes semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2012, to the holders of record of the 2041 Global Notes at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the related Interest Payment Date. Interest on the 2041 Global Notes will accrue from and including September 19, 2011, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but excluding the next Interest Payment Date or Maturity date, as the case may be. Interest on the 2041 Global Notes will be paid on the basis of a 360-day year comprised of twelve 30-day months. If an Interest Payment Date on the 2041 Global Notes falls on a date that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day.

11. The Global Notes shall be issued in the form of one or more Global Securities (the “Global Securities”). So long as the Global Notes shall be issued in whole in the form of the Global Securities, the principal of, premium, if any, and interest, if any, on the Global Notes shall be paid in immediately available funds to the Depositary or a nominee of the Depositary. If at any time the Global Notes are no longer represented by the Global Securities and are issued in definitive form (“Certificated Securities”), then the principal of, premium, if any, and interest, if any, on each Certificated Security at Maturity shall be paid to the Holder upon surrender of such Certificated Security at the office or agency maintained by the Company in the Borough of Manhattan, The City of New York (which shall initially be the office of The Bank of New York, an affiliate of The Bank of New York Mellon Trust Company, N.A., the Trustee), provided that such Certificated Security is surrendered to the Trustee, acting as Paying Agent, in time for the Paying Agent to make such payments in such funds in accordance with its normal procedures. Payments of interest with respect to Certificated Securities other than at Maturity may, at the option of the Company, be made by check mailed to the address of the Person entitled thereto as it appears on the Security Register on the relevant Regular or Special Record Date or by wire transfer in same day funds to such account as may have been appropriately designated to the Paying Agent by such Person in writing not later than such relevant Regular or Special Record Date. Each payment of principal, premium, if any, and interest, if any, shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Transfer of the Global Notes shall be registrable on the Securities Register upon the surrender of the Global Notes for registration

-5-

of transfer at the office or agency maintained by the Company in the Borough of Manhattan, The City of New York (which shall initially be the office of The Bank of New York, an affiliate of The Bank of New York Mellon Trust Company, N.A., the Trustee).

12. If the acquisition of Autonomy Corporation plc (“Autonomy”) pursuant to the recommended cash offer (the “Offer”) by Hewlett-Packard Vision B.V., an indirect wholly-owned subsidiary of the Company, for the entire issued and to be issued share capital of Autonomy is not consummated on or prior to October 1, 2012, or if prior to October 1, 2012, the Offer lapses or is withdrawn, the Company will redeem the Securities at a Redemption Price equal to 101% of the aggregate outstanding principal amount of the Securities, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to but excluding the Special Mandatory Redemption Date.

The “Special Mandatory Redemption Date” means the earlier to occur of (1) October 31, 2012, if the Autonomy acquisition has not been completed on or prior to October 1, 2012 or (2) the 30th day (or if such day is not a business day, the first business day thereafter) following the Offer lapsing or being withdrawn.

13. The Fixed Rate Global Notes are subject to redemption at the option of the Company.

14. The Company will have the right to redeem the Fixed Rate Global Notes, in whole or in part, on at least 30 days’ but no more than 60 days’ prior written notice mailed to the registered holders of the Fixed Rate Global Notes to be redeemed. The redemption price will be equal to the greater of (1) 100% of the principal amount of the Securities to be redeemed and (2) the sum, as determined by the Company based on the Reference Treasury Dealer Quotations, of the present value of the principal amount of the Securities to be redeemed and the remaining scheduled payments of interest thereon from the Redemption Date to the Maturity Date (the “Remaining Life”) (not including any portion of such payments of interest accrued as of the Redemption Date) discounted from the scheduled payment dates to the Redemption Date on a semi-annual basis at the Treasury Rate plus 35 basis points in the case of the 2015 Global Notes, 35 basis points in the case of the 2016 Global Notes, 35 basis points in the case of the 2021 Global Notes and 40 basis points in the case of the 2041 Global Notes, plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the Redemption Date.

If money sufficient to pay the redemption price of and accrued interest on the Fixed Rate Global Notes (or portions thereof) to be redeemed on the redemption date is deposited with the Trustee or Paying Agent on or before the redemption date and certain other conditions are satisfied, then on and after the redemption date, interest will cease to accrue on the Fixed Rate Global Notes (or such portion thereof) called for redemption and such Fixed Rate Global Notes will cease to be outstanding. If any redemption date is not a Business Day, the Company will pay the redemption price on the next Business Day without any interest or other payment due to the delay.

-6-

If fewer than all of the Fixed Rate Global Notes in one series are to be redeemed, the Trustee will select the Fixed Rate Global Notes in that series for redemption on a pro rata basis, by lot or by such other method as the Trustee deems appropriate and fair. No Fixed Rate Global Notes of $1,000 or less will be redeemed in part.

“Comparable Treasury Issue” means the United States Treasury security selected by a Reference Treasury Dealer appointed by the Company as having a maturity comparable to the Remaining Life that would be utilized, at the time of selection, and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity with the Remaining Life.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by each Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date; provided that if three such quotations cannot reasonably be obtained by the Company, but if two such quotations are obtained, then the average of the two quotations shall be used, and if only one such quotation can reasonably be obtained by the Company, then one quotation shall be used.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the applicable Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for the redemption date.

15. The Global Notes are not subject to any sinking fund or analogous provisions.

16. The Global Notes shall be issuable only in denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

22. The defeasance and covenant defeasance provisions of Article Thirteen of the Indenture will apply to each series of the Global Notes.

23. The Global Notes may not be converted into other securities or property.

The Global Notes will be represented by one or more Global Securities registered in the name of DTC or Cede & Co., as a nominee of DTC.

In the event that Certificated Securities are issued in exchange for a Global Security, the form of certificate evidencing the Certificated Security shall be in substantially the form of Global Security, with such grammatical and other changes as are necessary to evidence the Certificated Securities in definitive form rather than as Global Securities.

Capitalized terms used herein that are not otherwise defined herein shall have the meanings assigned to them in the Indenture.
