Dear Sirs and Mesdames:

Genworth Financial, Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and to sell to Morgan Stanley & Co. Incorporated, Deutsche Bank Securities Inc. and Goldman, Sachs & Co., as underwriters (the “Underwriters”), U.S. $600,000,000 principal amount of 6.15% Fixed-to-Floating Rate Junior Subordinated Notes due 2066 (the “Notes”). The Notes will be issued pursuant to an Indenture to be dated as of November 14, 2006 (the “Base Indenture”), between the Company and The Bank of New York Trust Company, N.A., as indenture trustee (the “Trustee”), as supplemented by the First Supplemental Indenture to be dated as of November 14, 2006 (the “First Supplemental Indenture”) between the Company and the Trustee. The Base Indenture, as supplemented by the First Supplemental Indenture, is referred to herein as the “Indenture.”

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, on Form S–3 (File No. 333-138437), relating to securities, including the Notes, to be issued from time to time by the Company. The registration statement as amended to the date of this Agreement is hereinafter referred to as the “Registration Statement,” and the related prospectus covering the Notes dated November 3, 2006 is hereinafter referred to as the “Base Prospectus.” For purposes of this Agreement, “Prospectus” means the final prospectus relating to the Notes, including any prospectus supplement thereto relating to the Notes, as filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations under the Securities Act of 1933, as amended (the “Securities Act”), and the term “preliminary prospectus” means the Base Prospectus, as supplemented by the Preliminary Prospectus Supplement dated November 7, 2006.

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and “Time of Sale Prospectus” means the Base Prospectus and the preliminary prospectus, together with the free writing prospectuses, if any, each identified on Schedule II hereto (which shall not include any Electronic Road Show as defined in Section 1(b) hereof). As used herein, the terms “Registration Statement,” “preliminary prospectus,” “Time of Sale Prospectus” and Prospectus shall include the documents, if any, incorporated by reference therein. The terms “supplement,” “amendment,” and “amend” as used herein with respect to the Registration Statement, the Base Prospectus, the Time of Sale Prospectus, the preliminary prospectus or any free writing prospectus shall include all documents subsequently filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are incorporated by reference therein.

In addition, the Company will enter into a Replacement Capital Covenant to be dated November 14, 2006 (the “Replacement Capital Covenant”) (as described in the Time of Sale Prospectus and the Prospectus) for the benefit of a specified class of Covered Debtholders (as defined in the Replacement Capital Covenant) pursuant to which the Company will covenant (on its own behalf and on behalf of its subsidiaries) not to redeem, repurchase or purchase, as applicable, the Notes on or before November 15, 2046, unless the Company complies with certain specified conditions.

8. Covenants of the Underwriters. The Underwriters covenant with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of the Underwriters that otherwise would not be required to be filed by the Company thereunder but for the action of the Underwriters (other than, for the avoidance of doubt, the final term sheet prepared by the Company and filed with the Commission pursuant to Section 6(k)). The Underwriters acknowledge and agree that, except as may be set forth in Schedule II hereto, the Company has not authorized or approved any “issuer information” (as defined in Rule 433(h)) for use in any free writing prospectus prepared by or on behalf of the Underwriters.

9. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any Electronic Road Show or the Prospectus (if used within the period set forth in paragraph (f) of Section 6 hereof and as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Underwriters expressly for use therein.

(b) Each Underwriter agrees, severally but not jointly, to indemnify and hold harmless the Company, the directors and officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the preliminary prospectus, the Time of Sale Prospectus, any other free writing

18

prospectus that the Company has filed or is required to file pursuant to Rule 433(d) of the Securities Act or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by the Underwriters on behalf of such Underwriter expressly for use in the Registration Statement, the preliminary prospectus, the Time of Sale Prospectus, any other free writing prospectus that the Company has filed or is required to file pursuant to Rule 433(d) of the Securities Act or the Prospectus or any amendment or supplement thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Underwriters. In the case of any such separate firm for the Company and such directors, officers and control persons of the Company, such firm shall be designated in writing by the

19

Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 9(a) or 9(b) is unavailable to an indemnified party in respect of any losses, claims, damages or liabilities referred to under such paragraph, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) if the indemnifying party is the Company, in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Notes, (ii) if the indemnifying person is an Underwriter, in such proportion as is appropriate to reflect the relative fault of such Underwriter on the one hand and the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities or (iii) if the allocation provided by clause 9(d)(i)or 9(d)(ii) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above or the relative fault referred to in clause 9(d)(ii) but also the relative fault (in cases covered by clause 9(d)(i)) or such relative benefits (in cases covered by clause 9(d)(ii)) of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Notes shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Notes. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the

20

Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective aggregate principal amount of Notes they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Notes.

10. Termination. The Underwriters may terminate this Agreement by notice given by the Underwriters to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in the State of New York or the United States shall have been declared by Federal or New York State authorities, or (iii) there shall have occurred any material outbreak, or material escalation, of hostilities or other national or international

21

calamity or crisis, of such magnitude and severity in its effect on the financial markets of the United States, in the reasonable judgment of the Underwriters, as to prevent or materially impair the marketing, or enforcement of contracts for sale, of the Notes.

11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Notes that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Notes to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Notes set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Underwriters may specify, to purchase the Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Notes that any Underwriter has agreed to purchase on such date pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such principal amount of Notes without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Notes and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes to be purchased, and arrangements satisfactory to the Underwriters and the Company for the purchase of such Notes are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Underwriters or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any one of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel)

22

reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

12. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. Nature of Underwriters’ Obligations. The Company acknowledges that in connection with the offering of the Notes: (a) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (b) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (c) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Notes.

16. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Notes, represents the entire agreement between the Company, on the one hand, and the Underwriters, on the other, with respect to the preparation of the preliminary prospectus, the Time of Sale Prospectus, the Prospectus, and the conduct of the offering, and the purchase and sale of the Notes.

FORM OF U.S. COMPANY COUNSEL LETTER

The primary purpose of our professional engagement was not to establish or confirm factual matters or financial or quantitative information, and many determinations involved in the preparation of the Registration Statement, the Time of Sale Prospectus and Prospectus are of a non-legal character. In addition, we have not undertaken any obligation to verify independently any of the factual matters set forth in the Registration Statement, the Time of Sale Prospectus and Prospectus. Consequently, in this letter we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus and Prospectus. Also, we do not make any statement herein with respect to any of the financial statements and related notes thereto, the financial statement schedules or the financial, statistical or accounting data contained in the Registration Statement, the Time of Sale Prospectus and Prospectus.

We have reviewed the Registration Statement, the Time of Sale Prospectus and Prospectus and we have participated in conferences with representatives of the Company, its independent public accountants, its special insurance regulatory counsel, its local counsel, you and your counsel, at which conferences the contents of the Registration Statement, the Time of Sale Prospectus and Prospectus and related matters were discussed.

Subject to the foregoing, we confirm to you that, on the basis of the information we gained in the course of performing the services referred to above, no facts have come to our attention which cause us to believe that (i) the Registration Statement, as of the effective date, or the Prospectus, as of its date, do not comply as to form in all material respects with the requirements of the Securities Act of 1933, as amended, and the Rules and Regulations thereunder, (ii) the Registration Statement, as of the effective date thereof, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading, (iii) the Time of Sale Prospectus, as of the date of the Underwriting Agreement, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iv) the Prospectus, as of its date or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.
