Item 1.01. Entry into a Material Definitive Agreement.

On September 9, 2009, Agilent Technologies, Inc. (the "Company") entered into an underwriting agreement with Barclays Capital Inc., Citigroup Global Markets Inc. and Credit Suisse Securities (USA) LLC, on behalf of the several underwriters named therein, in connection with the offer and sale of $250 million in aggregate principal amount of its 4.45% Senior Notes due 2012 (the "2012 Notes") and $500 million in aggregate principal amount of its 5.50% Senior Notes due 2015 (the "2015 Notes" and, together with the 2012 Notes, the "Notes") in an underwritten public offering (the "Offering"). The underwriting agreement contains customary representations and covenants and includes the terms and conditions of the sale of the Notes, indemnification and contribution obligations and other terms and conditions customary in agreements of this type.

The Notes are being issued pursuant to the Indenture, dated as of October 24, 2007, (the "Indenture") between the Company and U.S. Bank National Association, as trustee (the "Trustee"), and, in connection with the 2012 Notes, the Second Supplemental Indenture, to be dated as of September 14, 2009, between the Company and the Trustee (the "Second Supplemental Indenture"), and, in connection with the 2015 Notes, the Third Supplemental Indenture, to be dated as of September 14, 2009, between the Company and the Trustee (the "Third Supplemental Indenture") with the following principal terms.

The 2012 Notes and 2015 Notes are being issued at a price to the public of 99.911% and 99.687%, respectively, of their principal amount. The 2012 Notes and 2015 Notes will (a) mature on September 14, 2012 and September 14, 2015, respectively and (b) bear interest at a fixed rate of 4.45% and 5.50%, respectively, per annum, payable semi-annually on March 14 and September 14 of each year, commencing on March 14, 2010. The Notes are unsecured and will rank equally in right of payment with all of the Company's other senior unsecured indebtedness.

The Notes are redeemable, in whole or in part at any time, at the Company's option, at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to, but not including, the date of redemption: (a) 100% of the principal amount of the Notes to be redeemed; or (b) the sum of the present values of the remaining scheduled payments thereon discounted to the date of redemption, on a semi-annual basis, at the applicable Treasury Rate (as defined in the Second Supplemental Indenture or the Third Supplemental Indenture, as applicable) plus 50 basis points. In addition, upon the occurrence of a Change of Control (as defined in the Second Supplemental Indenture or the Third Supplemental Indenture, as applicable) of the Company that results in a decrease of the ratings of the 2012 Notes and/or the 2015 Notes by any of Fitch Ratings Ltd. ("Fitch"), Moody's Investors Services Inc. ("Moody's") or Standard & Poor's Rating Services ("S&P"), if they are then rating the 2012 Notes or the 2015 Notes, as applicable, such that the 2012 Notes and/or the 2015 Notes are rated below investment grade, the Company will be required to make an offer to repurchase the 2012 Notes and/or the 2015 Notes, as applicable, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to, but not including, the date of repurchase.

The Indenture contains covenants that limit the ability of the Company and its subsidiaries to grant liens on certain assets to secure indebtedness, and to enter into sale and lease-back transactions, subject to certain exceptions.

The Notes are subject to customary events of default, including: (a) the Company's failure to pay principal or premium, if any, on the Notes when due at maturity, upon redemption or otherwise; (b) the Company's failure to pay interest for 30 days after the interest becomes due and payable; (c) the Company's failure to repurchase notes tendered for repurchase following the occurrence of a Change of Control Repurchase Event (as defined in the Second Supplemental Indenture or the Third Supplemental Indenture, as applicable);
(d) the Company's failure to perform, or its breach of, any other covenant or warranty in the Indenture for 90 days after either the Trustee or holders of at least 25% in principal amount of the outstanding Notes have given the Company written notice of the default or breach in the manner required by the Indenture;
(e) specified events involving the Company's bankruptcy, insolvency or

reorganization; and (f) (1) a failure to make any payment at maturity, including any applicable grace period, on any indebtedness of the Company (other than indebtedness of the Company owing to any of its subsidiaries) outstanding in an amount in excess of $100 million and continuance of this failure to pay or (2) a default on any indebtedness of the Company (other than indebtedness owing to any of its subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of $100 million without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (1) or (2) above.

The descriptions above are summaries and are qualified in their entirety by the Indenture, filed as Exhibit 4.01 to the Company's Registration Statement on Form S-3 filed on October 24, 2007 (File No. 333-146892) and the Underwriting Agreement, the Second Supplemental Indenture, the Third Supplemental Indenture, the form of 2012 Notes and the form of 2015 Notes, filed as Exhibit No. 1.01, 4.01, 4.02, 4.03 and 4.04 hereto, respectively, and, in each case, incorporated by reference herein.
