The undersigned registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to the registration statement: (i) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof ) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (3) (a) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering, (3)(b) that, for purposes of determining any liability under the Securities Act of 1933, each filing if the registrant's annual report pursuant to Section 13(a) or 15 (d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant, Allstate Life Insurance Company, pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES Pursuant to the requirements of the Securities Act of 1933, Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized in the Township of Northfield, State of Illinois on the 27th day of September, 2004.

Board of Directors
Allstate Life Insurance Company

We have made a review, in accordance with standards of the Public Company
Accounting Oversight Board (United States), of the unaudited interim
consolidated financial information of Allstate Life Insurance Company and
subsidiaries for the periods ended March 31, 2004 and 2003, and June 30, 2004
and 2003, and have issued our reports dated May 7, 2004, and August 10, 2004,
respectively; because we did not perform an audit, we expressed no opinion on
that information.

We are aware that our reports referred to above, which were included in your
Quarterly Reports on Form 10-Q for the quarters ended March 31, 2004, and June
30, 2004, are being used in this Registration Statement.

We also are aware that the aforementioned reports, pursuant to Rule 436(c) under
the Securities Act of 1933, are not considered a part of the Registration
Statement prepared or certified by an accountant or a report prepared or
certified by an accountant within the meaning of Sections 7 and 11 of that Act.

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


We consent to the incorporation by reference in this Registration Statement of
Allstate Life Insurance Company on Form S-3 of our report dated February 4, 2004
(which report expresses an unqualified opinion and includes an explanatory
paragraph relating to changes in the methods of accounting for embedded
derivatives in modified coinsurance agreements and variable interest entities in
2003), appearing in the Annual Report on Form 10-K of Allstate Life Insurance
Company for the year ended December 31, 2003, and to the reference to us under
the heading "Experts" in the Prospectus, which is part of this Registration
Statement.

Exhibit 23 (b) CONSENT OF FOLEY & LARDNER LLP We hereby consent to the reference to our firm under the caption "Legal Matters" in the prospectus included in the initial Form S-3 Registration Statement of Allstate Life Insurance Company, filed on September 27, 2004. /s/ Foley & Lardner LLP FOLEY & LARDNER LLP Washington, D.C.

Exhibit 99 (a)

Experts

The consolidated financial statements and the related consolidated financial
statement schedules incorporated in this prospectus by reference from the
Allstate Life Insurance Company Annual Report on Form 10-K for the year ended
December 31, 2003 have been audited by Deloitte & Touche LLP, an independent
registered public accounting firm, as stated in their report, which is
incorporated by reference herein (which report expresses an unqualified opinion
and includes an explanatory paragraph relating to changes in the methods of
accounting for embedded derivatives in modified coinsurance agreements and
variable interest entities in 2003), and have been so incorporated in reliance
upon the report of such firm given upon their authority as experts in accounting
and auditing.

With respect to the unaudited interim financial information for the periods
ended March 31, 2004 and 2003 and June 30, 2004 and 2003 which is incorporated
herein by reference, Deloitte & Touche LLP, an independent registered public
accounting firm, have applied limited procedures in accordance with standards of
the Public Company Accounting Oversight Board (United States) for a review of
such information. However, as stated in their reports included in the Company's
Quarterly Reports on Form 10-Q for the quarters ended March 31, 2004 and June
30, 2004 and incorporated by reference herein, they did not audit and they do
not express an opinion on that interim financial information. Accordingly, the
degree of reliance on their reports on such information should be restricted in
light of the limited nature of the review procedures applied. Deloitte & Touche
LLP are not subject to the liability provisions of Section 11 of the Securities
Act of 1933 for their reports on the unaudited interim financial information
because those reports are not "reports" or a "part" of the registration
statement prepared or certified by an accountant within the meaning of Sections
7 and 11 of the Act.
