The obligations of the Underwriters shall be subject, in the discretion of the Representatives, to the condition that all representations and warranties (except in the case of the Optional Time of Delivery the representations and warranties in Sections 1(c), 1(g) and 1(o)) and other statements of the Company herein shall be true and correct, at and as of each Time of Delivery (it being understood, however, that in the case of the Optional Time of Delivery the representations and warranties in Sections 1(h) and 1(j) shall be limited to the Optional Shares), the condition that the Company shall have performed, in all material respects, all of its obligations hereunder theretofore to be performed and the following additional conditions:

(c) Xxxxxxxx & Xxxxxxxx LLP, counsel for the Company, shall have furnished to the Representatives their opinion or opinions, dated each Time of Delivery, to the effect set forth in Schedule III hereto (it being understood, however, that in the case of the Optional Time of Delivery, that the opinion shall only cover the opinion in paragraph (1) and, with respect to the Optional Shares, the opinion in paragraph (2) set forth in Schedule III hereto);

(d) Xxxxxxxx X. Xxxxxxx, Senior Vice President, Secretary and Deputy General Counsel of the Company, shall have furnished to the Representatives her opinion, dated each Time of Delivery, to the effect set forth in Schedule IV hereto (it being understood, however, that in the case of the Optional Time of Delivery, that the opinion shall only cover the opinion in paragraphs (i), (ii) and (iii) set forth in Schedule IV hereto and shall be limited to the Optional Shares);

(e) On the date of the Prospectus at a time prior to the execution of this Agreement and the First Time of Delivery, the independent registered public accounting firm who

- 11 -

have audited the financial statements of the Company and its subsidiaries incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus shall have furnished to the Representatives a letter, dated the respective dates of delivery thereof, to the effect set forth in Schedule V hereto, and with respect to such letter dated such Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance satisfactory to the Representatives;

(f) Since the respective dates as of which information is given in the Pricing Disclosure Package (excluding any amendment or supplement thereto) and prior to the First Time of Delivery, there shall not have been in the reasonable judgment of the Representatives any Material Adverse Change, otherwise than as set forth or contemplated in the Prospectus (excluding any amendment or supplement thereto);

(g) The Company shall have furnished or caused to be furnished to the Representatives a certificate of the Chief Executive Officer, the President, any Vice Chairman, any Executive or Senior Vice President or any Vice President and a principal financial or accounting officer of the Company, dated each Time of Delivery, in which such officers, to the best of their knowledge after reasonable investigation, shall state that the representations and warranties of the Company in this Agreement (except in the case of the Optional Time of Delivery the representations and warranties in Sections 1(c), 1(g) and 1(o), and it being understood, however, that in the case of the Optional Time of Delivery, the representations and warranties in Section 1(h) and 1(j) shall be limited to the Optional Shares) are true and correct, in all material respects, as of each Time of Delivery, that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied, in all material respects, at or prior to each Time of Delivery, that no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are threatened by the Commission, and that, with respect to the First Time of Delivery only, since the respective dates as of which information is given in the Pricing Disclosure Package, there has not been any Material Adverse Change, otherwise than as set forth or contemplated in the Prospectus as amended or supplemented in accordance with Section 5(a) hereof;

(h) On or after the date hereof and prior to the First Time of Delivery, there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange if the effect of any such event, in the reasonable judgment of the Representatives, is to make it impracticable or inadvisable to proceed with the purchase by the Underwriters of the Securities from the Company; (ii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities; (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, other than any such outbreak, escalation or declaration arising out of or relating to the U.S. war on terrorism that does not represent a significant departure from the conditions that exist at the date hereof, if the effect of any such event in the reasonable judgment of the Representatives is to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the Pricing Disclosure Package or the Prospectus as amended or supplemented in accordance with Section 5(a) hereof; (iv) the suspension of trading in the Common Stock on the New York Stock Exchange, if the effect of such event in the reasonable judgment of the Representatives is to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the

- 12 -

Pricing Disclosure Package or the Prospectus as amended or supplemented in accordance with Section 5(a) or (v) any downgrading in the rating accorded the Company’s senior debt securities by Xxxxx’x Investors Service, a subsidiary of Xxxxx’x Corporation, or Standard & Poor’s, a division of the XxXxxx-Xxxx Companies, Inc., if the effect of such event in the reasonable judgment of the Representatives is to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the Pricing Disclosure Package or the Prospectus as amended or supplemented in accordance with Section 5(a);

(i) The Securities to be delivered on the First Time of Delivery or Optional Time of Delivery, as the case may be, shall have been approved for listing on the New York Stock Exchange, subject to official notice of issuance; and

9. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package (or any amendment or supplement thereto), or any Issuer Free Writing Prospectus, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and will reimburse such Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter expressly for use therein; and provided, further, that the foregoing indemnity agreement contained in this Section 9(a), with respect to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Securities, where (i) prior to the Applicable Time the Company shall have notified such Underwriter that the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus contains an untrue statement of material fact or omits to state therein a material fact necessary in order to make the statements therein not misleading, (ii) such untrue statement or omission of a material fact was corrected in a further amendment or supplement to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing

- 13 -

Prospectus, or any amendment or supplement thereto, or, where permitted by law, an Issuer Free Writing Prospectus, and such corrected Prospectus or Issuer Free Writing Prospectus was provided to such Underwriter prior to the Applicable Time, (iii) such corrected Registration Statement, Prospectus, Preliminary Prospectus or Issuer Free Writing Prospectus (excluding any document incorporated by reference therein) was not conveyed to such person at or prior to the contract for sale of the Securities to such person and (iv) such loss, claim, damage or liability would not have occurred had the corrected Registration Statement, Prospectus, Preliminary Prospectus or Issuer Free Writing Prospectus (excluding any document incorporated by reference therein) been conveyed to such person as provided for in clause (iii) above.

(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company or such controlling person may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under such subsection, except to the extent that it has been prejudiced by such failure. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. 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 that is not subject to further appeal, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party

- 14 -

is or could have been a party and indemnification could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters of the Securities on the other from the offering of the Securities to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters of the Securities on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters in respect thereof. The relative fault 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 required to be stated therein or necessary to make the statements therein not misleading relates to information supplied by the Company on the one hand or by such Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) 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 which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Securities in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

- 15 -

(e) The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the respective Underwriters and each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter, the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the applicable Time of Delivery for such Securities for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such Securities which remains unpurchased does not exceed one-tenth of the aggregate number of all the Securities to be purchased at the applicable Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities which such Underwriter agreed to purchase under this Agreement relating to such Securities and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of Securities which remains unpurchased exceeds one-tenth of the aggregate number of all the Securities to be purchased at the applicable Time of Delivery, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement relating to such Securities shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as

- 16 -

provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

12. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 8 hereof is not satisfied (other than any termination pursuant to Section 8(h)(i), (ii) or (iii) hereof), or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through Citigroup Global Markets Inc. and X.X. Xxxxxx Securities Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Securities.

13. In all dealings hereunder, the Representatives of the Underwriters of the Securities shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly.

All statements, requests, notices and advices hereunder shall be in writing, or by telephone if promptly confirmed in writing, and if to an Underwriter, shall be sufficient in all respects when delivered or sent by facsimile transmission or registered mail as set forth in Schedule I hereto under such Underwriter’s name, and if to the Company shall be sufficient in all respects when delivered or sent by registered mail to 70 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Facsimile Transmission No. (000) 000-0000, Attention: Corporate Secretary.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 9 and Section 11 hereof, their respective officers and directors and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, personal representatives, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently

- 17 -

advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate.

16. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

17. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

18. Time shall be of the essence in this Agreement.

19. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all of such counterparts shall together constitute one and the same instrument.

- 18 -

If the foregoing is in accordance with your understanding, please sign and return to us five counterparts hereof, whereupon this letter and the acceptance by each of you thereof shall constitute a binding agreement between the Company and each of you in accordance with its terms.

•

if the Stock Price is between two Stock Price amounts on the table or the Effective Date is between two dates on the table, the amount of make-whole shares will be determined by straight line interpolation between the make-whole share amounts set

			forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 360-day year;

	•		if the Stock Price is in excess of $120.00 per share (subject to adjustment as described above), then the make-whole share amount will be zero; and

	•		if the Stock Price is less than $10.00 per share (subject to adjustment as described above), or the “minimum stock price,” then the make-whole share amount will be determined as if the stock price equaled the minimum stock price, using straight line interpolation, as described above, if the Effective Date is between two dates on the table.

Form of Opinion of Xxxxxxxx & Xxxxxxxx LLP

[Name and Address of Underwriters]

Ladies and Gentlemen:

In connection with the several purchases today by you and the other Underwriters named in Schedule I to the Underwriting Agreement, dated May 12, 2008 (the “Underwriting Agreement”), between American International Group, Inc., a Delaware corporation (the “Company”), and you, as Representatives of the several Underwriters named therein (the “Underwriters”), of 171,052,631 shares (the “Securities”) of the Company’s common stock, par value $2.50 per share (the “Common Stock”), we, as counsel for the Company, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

(1) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Delaware.

(2) All outstanding shares of the Company’s Common Stock, including the Securities, have been duly authorized and validly issued and are fully paid and nonassessable.

(3) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

We have relied as to certain matters upon information obtained from public officials, officers of the Company and other sources believed by us to be responsible, and we have assumed that the certificates for the outstanding shares of Common Stock, including the Securities, conform to the specimen thereof examined by us and have been duly countersigned by a transfer agent and duly registered by a registrar of the Common Stock, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

Very truly yours,

[Name and Address of Underwriters]

Ladies and Gentlemen:

This is with reference to the registration under the Securities Act of 1933 (the “Securities Act”) and offering of 171,052,631 shares (the “Securities”) of common stock, par value $2.50 per share, of American International Group, Inc. (the “Company”).

Two Registration Statements relating to the Securities (File Nos. 333-143992 and 333-106040) were filed on different dates on Form S-3 in accordance with procedures of the Securities and Exchange Commission (the “Commission”) permitting a delayed or continuous offering of securities pursuant thereto and, if appropriate, a post-effective amendment, document incorporated by reference therein or prospectus supplement that provides information relating to the terms of the securities and the manner of their distribution. References in this letter to the Registration Statement refer to the latest filed Registration Statement.

The Securities have been offered by the Prospectus, dated July 13, 2007 (the “Basic Prospectus”), as supplemented by the Prospectus Supplement, dated May 12, 2008 (the “Prospectus Supplement”), which updates or supplements certain information contained in the Basic Prospectus. The Basic Prospectus, as supplemented by the Prospectus Supplement, does not necessarily contain a current description of the Company’s business and affairs since, pursuant to Form S-3, it incorporates by reference certain documents filed with the Commission that contain information as of various dates.

As counsel to the Company, we reviewed the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the documents listed in Schedule A (those listed documents, taken together with the Basic Prospectus, being referred to herein as the “Pricing Disclosure Package”) and participated in discussions with your representatives and those of the Company and its accountants. Between the date of the Prospectus Supplement and the time of delivery of this letter, we participated in further discussions with your representatives and those of the Company, its accountants and its counsel concerning certain matters relating to the Company and reviewed certificates of certain officers of the Company, a letter addressed to you from the Company’s accountants and an opinion addressed to you from counsel to the Company. On the basis of the information that we gained in the course of the performance of the services referred to above, considered in the light of our understanding of the applicable law (including the requirements of Form S-3 and the character of prospectus contemplated thereby) and the experience we have gained through our practice under the Securities Act, we confirm to you that, in our opinion, each part of the Registration Statement, when such part became effective, and the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement,

III-2

appeared on their face to be appropriately responsive, in all material respects relevant to the offering of the Securities, to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Further, nothing that came to our attention in the course of such review has caused us to believe that, insofar as relevant to the offering of the Securities,

(a) any part of the Registration Statement, when such part became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or

(b) the Pricing Disclosure Package, as of 5:00 P.M. on May 12, 2008 (which you have informed us is prior to the time of the first sale of the Securities by any Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(c) the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

We also advise you that nothing that came to our attention in the course of the procedures described in the second sentence of this paragraph has caused us to believe that (a) the Basic Prospectus, as supplemented by the Prospectus Supplement, or (b) the Pricing Disclosure Package, as of the time of delivery of this letter, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, except for those made under the captions “Description of Common Stock AIG May Offer” in the Basic Prospectus and “Description of the Equity Units,” “Certain United States Tax Consequences to Non-U.S. Holders of Common Stock” and “Underwriting” in the Prospectus Supplement insofar as they relate to provisions of the Securities, equity units and the Underwriting Agreement therein described or insofar as they relate to provisions of United States Federal tax law therein described. Also, we do not express any opinion or belief as to the financial statements or other financial data derived from accounting records contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package or as to the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditors’ attestation report thereon, each as included in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package.

This letter is furnished by us, as counsel to the Company, to you, as Representatives of the Underwriters, solely for the benefit of the Underwriters in their capacity as such, and may not be relied upon by any other person. This letter may not be quoted, referred to or furnished to any purchaser or prospective purchaser of the Securities and may not be used in furtherance of any offer or sale of the Securities.

SCHEDULE IV

Form of Opinion of Xxxxxxxx X. Xxxxxxx

Xxx 16, 2008

[Name and Address of Underwriters]

Ladies and Gentlemen:

I am Senior Vice President, Secretary and Deputy General Counsel of American International Group, Inc., a Delaware corporation (the “Company”), and, as such, I am generally familiar with the corporate affairs of the Company.

This opinion is rendered in connection with the several purchases today by you and the other Underwriters named in Schedule I to the Underwriting Agreement, dated May 12, 2008 (the “Underwriting Agreement”), between the Company and you, as Representatives of the several Underwriters named therein (the “Underwriters”), of 171,052,631 shares (the “Securities”) of the Company’s common stock, par value $2.50 per share (the “Common Stock”).

Two Registration Statements relating to the Securities (File Nos. 333-143992 and 333-106040) were filed on Form S-3 under the Securities Act of 1933 (the “Act”) on different dates. The latest filed Registration Statement was declared effective by the Securities and Exchange Commission (the “Commission”) on July 13, 2007. References in this letter to the Registration Statement refer to the latest filed Registration Statement. The Securities have been offered by the Prospectus dated July 13, 2007 (the “Basic Prospectus”), as supplemented by the Prospectus Supplement, dated May 12, 2008 (the “Prospectus Supplement”).

In rendering my opinion, I, as Senior Vice President, Secretary and Deputy General Counsel of the Company, have examined the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the documents listed in Schedule A hereto (those listed documents, taken together with the Basic Prospectus as amended or supplemented immediately prior to the Applicable Time (as defined below) being referred to herein as the “Pricing Disclosure Package”), and I have examined such corporate records, certificates and other documents, and have reviewed such questions of law, as I have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination and review, it is my opinion that:

(i) The Company has authorized capital stock as set forth in the Company’s Restated Certificate of Incorporation, as amended, as incorporated by reference in the Pricing Disclosure Package and the Basic Prospectus; and all outstanding shares of the Company’s Common Stock, including the Securities, have been duly authorized and validly issued and are fully paid and nonassessble.

(ii) The issue and sale of the Securities, and the compliance by the Company with all of the provisions of the Underwriting Agreement, will not result in a breach of any of the

IV-1

terms or provisions of, or constitute a default under, any material indenture, mortgage, deed of trust, loan agreement, or other material agreement or instrument in effect on the date hereof and known to me, to which the Company is a party or by which the Company may be bound or to which any of the property or assets of the Company is subject or violate any judgment, order or decree of any court or governmental body applicable to the Company, except for such breaches, defaults and violations that would not individually or in the aggregate have a Material Adverse Effect (as defined in the Underwriting Agreement) or affect the validity of the Securities, nor will such action result in any violation of the provisions of the Restated Certificate of Incorporation, as amended, or the By-Laws of the Company in effect on the date hereof.

(iii) No consent, approval, authorization, order, registration or qualification of or with any court or any regulatory authority or other governmental body is required for the issuance and sale of the Securities or the consummation by the Company of the other transactions contemplated by the Underwriting Agreement, except such as have been obtained under the Act, such consents, approvals, authorizations, orders, registrations and qualifications required to list the Securities on the New York Stock Exchange and such consents, approvals, authorizations, orders, registrations or qualifications the failure to obtain or make would not individually or in the aggregate have a Material Adverse Effect or affect the validity of the Securities and as may be required under state securities or Blue Sky laws (including insurance laws of any state relating to offers and sales of securities in such state) in connection with the purchase and distribution of the Securities by the Underwriters, as contemplated by the Underwriting Agreement.

(iv) To the best of my knowledge and information, there are no contracts or other documents required to be summarized or disclosed or filed as exhibits to the Registration Statement, other than those summarized or disclosed in the Registration Statement or filed as exhibits thereto, and there are no legal or governmental proceedings pending or threatened of a character required to be disclosed in the Registration Statement and the Basic Prospectus, as amended or supplemented by the Prospectus Supplement, which are not disclosed.

(v) Nothing which came to my attention has caused me to believe that, insofar as relevant to the offering of the Securities,

(b) the Pricing Disclosure Package, as of 5:00 P.M. on May 12, 2008 (the “Applicable Time”) (which you have informed me is prior to the time of the first sale of the Securities by any Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(c) the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any

IV-2

material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(vi) The documents incorporated by reference in the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the Act and the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder.

In rendering the opinion in paragraph (v), (A) I assume no responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, except for those made under the captions “Description of Common Stock AIG May Offer” in the Basic Prospectus and “Description of the Equity Units” in the Prospectus Supplement insofar as they constitute summaries of the documents therein described, and (B) I express no opinion or belief as to the financial statements or other financial data derived from accounting records contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, or as to the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditors’ attestation report thereon, each as included in the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the Pricing Disclosure Package.

In rendering the opinion in paragraph (vi), I express no opinion or belief as to the financial statements or other financial or statistical data contained in the documents incorporated by reference in the Basic Prospectus or the Prospectus Supplement, or as to the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditors’ attestation report thereon, each as included in the documents incorporated by reference in the Basic Prospectus and the Prospectus Supplement.

The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware, and I am expressing no opinion as to the effect of the laws of any other jurisdiction.

I have relied as to certain matters upon information obtained from public officials, officers of the Company and other sources believed by me to be responsible, and I have assumed that the certificates for the outstanding shares of Common Stock, including the Securities, conform to the specimen thereof examined by me and have been duly countersigned by a transfer agent and duly registered by a registrar of the Common Stock, and that the signatures on all documents examined by me are genuine, assumptions which I have not independently verified.

SCHEDULE V

Form of Letter of Independent Registered Public Accounting Firm

May 12, 2008

American International Group, Inc.

and

The Underwriters listed on Schedule I

Ladies and Gentlemen:

We have audited:

the consolidated financial statements of American International Group, Inc. (the “Company”) and subsidiaries as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 included in the Company’s annual report on Form 10-K for the year ended December 31, 2007 (the “Form 10-K”),

2. the related financial statement schedules included in the Form 10-K, and

the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007.

The consolidated financial statements and financial statement schedules referred to above are incorporated by reference in the registration statements (Nos. 333-143992 and 333-106040) on Form S-3 filed by the Company under the Securities Act of 1933 (the “Act”); our report (which contains an adverse opinion on the effectiveness of internal control over financial reporting) with respect to the audits referred to above is also incorporated by reference in such registration statements. Such registration statements, of which the Prospectus dated July 13, 2007 forms a part, as supplemented by the Prospectus Supplement dated May 12, 2008 are herein collectively referred to as the “Registration Statement.” This letter is furnished with respect to the offering of the Company’s 171,052,631 shares of Common Stock.

In connection with the Registration Statement:

We are an independent registered public accounting firm with respect to the Company within the meaning of the Act and the applicable rules and regulations thereunder adopted by the Securities and Exchange Commission (the “SEC”) and the Public Company Accounting Oversight Board (United States) (the “PCAOB”).

In our opinion, the consolidated financial statements and financial statement schedules audited by us and incorporated by reference in the Registration Statement comply as to form

in all material respects with the applicable accounting requirements of the Act and the Securities Exchange Act of 1934 and the related rules and regulations adopted by the SEC.

3.		We have not audited any financial statements of the Company as of any date or for any period subsequent to December 31, 2007; although we have conducted an audit for the year ended December 31, 2007, the purpose (and therefore the scope) of such audit was to enable us to express our opinion on the consolidated financial statements as of December 31, 2007 and for the year then ended, but not on the financial statements for any interim period within such year. Therefore, we are unable to and do not express any opinion on the unaudited consolidated balance sheet as of March 31, 2008 and the unaudited consolidated statements of income (loss) , comprehensive income (loss), and cash flows for the three-month periods ended March 31, 2008 and 2007, included in the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2008, incorporated by reference in the Registration Statement, or on the Company’s financial position, results of operations or cash flows as of any date or for any period subsequent to December 31, 2007. Also, we have not audited the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007. Therefore, we do not express any opinion on the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007.

4.		For purposes of this letter, we have read the minutes of the 2008 meetings of the Board of Directors and Committees of the Board of Directors of the Company as set forth in the minute books at May 8, 2008, officials of the Company having advised us that the minutes of all such meetings through that date were set forth therein, except for the minutes of the meetings listed below which were not approved in final form, for which agendas were provided to us; officials of the Company have represented that such agendas include all substantive actions taken at such meetings:

	a.		the Board of Directors (the “Board”) - the February 26, 2008, March 12, 2008, May 5, 2008, May 6, 2008 and May 8, 2008 meetings;

	b.		the Audit Committee of the Board — the January 15, 2008, February 7, 2008, February 26, 2008, March 11, 2008, April 16, 2008 and May 5, 2008 meetings;

	c.		the Compensation and Management Resources Committee of the Board — the February 26, 2008 and March 11, 2008 meetings;

	d.		the Finance Committee of the Board - the December 13, 2007, February 12, 2008, March 11, 2008 April 17, 2008 and May 5, 2008 meetings;

	e.		the Nominating and Corporate Governance Committee of the Board — the January 15, 2008 and March 11, 2008 meetings;

V-2

	f.		the Public Policy and Social Responsibility Committee of the Board — the January 15, 2008 and April 16, 2008 meetings, and

	g.		the Regulatory, Compliance and Legal Committee of the Board — the January 16, 2008 and March 12, 2008 meetings.

We have carried out other procedures to May 8, 2008 (our work did not extend to the period from May 9, 2008 to May 12, 2008, inclusive) as follows:

With respect to the three-month periods ended March 31, 2008 and 2007, we have:

	(i)		performed the procedures (completed on May 8, 2008) specified by the PCAOB for a review of interim financial information as described in SAS No. 100, Interim Financial Information, on the unaudited consolidated financial statements as of and for the three-month periods ended March 31, 2008 and 2007 included in the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2008 (the “March 31, 2008 Form 10-Q”), incorporated by reference in the Registration Statement; and

	(ii)		inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the unaudited consolidated financial statements referred to in (i) above comply as to form in all material respects with the applicable accounting requirements of the Securities Exchange Act of 1934 as it applies to the Form 10-Q and the related rules and regulations adopted by the SEC.

The foregoing procedures do not constitute an audit made in accordance with standards of the PCAOB. Also, they would not necessarily reveal matters of significance with respect to the comments in the following paragraph. Accordingly, we make no representations as to the sufficiency of the foregoing procedures for your purposes.

Nothing came to our attention as a result of the foregoing procedures, however, that caused us to believe that:

	(i)		Any material modifications should be made to the unaudited consolidated financial statements described in 4, incorporated by reference in the Registration Statement, for them to be in conformity with generally accepted accounting principles.

	(ii)		The unaudited consolidated financial statements described in 4 do not comply as to form in all material respects with the applicable accounting requirements of the Securities Exchange Act of 1934 as it applies to the Form 10-Q and the related rules and regulations adopted by the SEC.

It should be noted that effective January 1, 2008, the Company adopted FAS 157 “Fair Value Measurements”, FAS 159 “The Fair Value Option for Financial Assets and Financial Liabilities” and FSP FIN 39-1 “Amendment of FASB Interpretation No. 39”.

V-3

6.		Company officials have advised us that no consolidated financial data as of any date or for any period subsequent to March 31, 2008 are available; accordingly, the procedures carried out by us with respect to changes in financial statement items after March 31, 2008 have, of necessity, been limited. We have inquired of certain officials of the Company who have responsibility for financial and accounting matters as to whether (a) at May 8, 2008 there was any change in the capital stock, increase in long-term debt, or decrease in consolidated shareholders’ equity of the Company as compared with amounts shown in the March 31, 2008 unaudited consolidated balance sheet incorporated by reference in the Registration Statement; or (b) for the period from April 1, 2008 to May 8, 2008, there was any decrease, as compared with the corresponding period in the preceding year, in consolidated net income.

		Those officials referred to above stated that due to the fact that there is no consolidated financial data available subsequent to March 31, 2008, they are unable to comment as to whether there was any such change, increase or decrease, except in all instances for changes, increases or decreases that the Registration Statement discloses have occurred or may occur.

7.		For purposes of this letter, we have also read the items identified by you on the attached pages from the Form 10-K and the March 31, 2008 Form 10-Q incorporated by reference in the Registration Statement and have performed the following procedures, which were applied as indicated with respect to the letters explained below. We make no comment as to whether the SEC would view any non-GAAP financial information included or incorporated by reference in the Registration Statement as being compliant with the requirements of Regulation G or Item 10 of Regulation S-K.

In order to induce you to enter into the Underwriting Agreement, the undersigned agrees that, for a period (the “Lock-Up Period”) beginning on the date hereof and ending on, and including, the date that is 90 days after the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of [Name of Underwriter], (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission (the “Commission”) promulgated thereunder (the “Exchange Act”) with respect to, any Common Stock or any other securities of the Company that are substantially similar to Common Stock, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, in each case, in which the undersigned has a “pecuniary interest” (within the meaning of Rule 16a-1(a)(2) under the Exchange Act), whether any such transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock or any other securities of the Company that are substantially similar to Common Stock, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, whether any such transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii). The foregoing sentence shall not apply to (a) the sale of shares of Common Stock upon the exercise of options to purchase Common Stock or the vesting, delivery or settlement of restricted shares, restricted stock units or other awards to provide for any withholding taxes on the exercise, vesting, delivery or settlement thereof or to pay the exercise price thereof, in each case pursuant to employee benefit plans and related plans as in effect on the date hereof or awards previously granted by Starr International Company, Inc., (b) bona fide gifts to tax exempt charitable organizations (other than private charitable foundations), (c) the contribution of Common Stock to a grantor retained annuity trust of which the undersigned is a trustee and the undersigned’s immediate family members (or trusts for their benefit) are the sole beneficiaries, (d) dispositions to any immediate family member or any trust or similar entity for the direct or indirect benefit of the

undersigned and/or the immediate family of the undersigned, provided that such trust or similar entity agrees in writing to be bound by the terms of this Lock-Up Agreement, or (e) any other transaction that would not be required to be reported pursuant to Section 16(a) of the Exchange Act as a result of the applicable person no longer being an executive officer or director for Section 16(a) reporting purposes, provided, that no filing under Section 16(a) of the Exchange Act shall be voluntarily made during the Lock-Up Period.
