SUPPLEMENT DATED SEPTEMBER 30, 2002

TO

PROSPECTUS DATED APRIL 30, 2002, AS SUPPLEMENTED

FOR

FUTURITY SELECT FOUR VARIABLE AND FIXED ANNUITY

ISSUED BY SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)

SUN LIFE OF CANADA (U.S.) VARIABLE ACCOUNT F

Effective September 30, 2002, seven new Funds will be available for investment under the above-captioned prospectus ("Prospectus"). As a result of the addition of the new Funds, the Prospectus is amended and supplemented as follows:

1. The list of the available investment options appearing on the cover page of the Prospectus is supplemented by the addition of the following Funds:

Franklin Templeton Variable Insurance

    Products Trust

   Templeton Growth Securities Fund - Class 2

   Templeton Foreign Securities Fund - Class 2

PIMCO Variable Insurance Trust

   PIMCO Real Return Portfolio

   PIMCO Total Return Portfolio

   PIMCO Emerging Markets Bond Portfolio

   PIMCO High Yield Portfolio

First Eagle SoGen Variable Funds, Inc.

   First Eagle SoGen Overseas Variable Fund

2. The table describing the "Underlying Fund Annual Expenses" is hereby amended and supplemented as follows:

UNDERLYING FUND ANNUAL EXPENSES¹

(numbers in brackets represent expenses before fee waivers or expense reimbursements)²

(as a percentage of Fund net assets)

	Management	Other Fund	12b-1 or	Total Annual
Fund	Fees	Expenses	Service Fees	Fund Expenses
Franklin Templeton Variable Insurance     Products Trust
Templeton Growth Securities Fund, Class 2*	0.80%	0.05%	0.25%	1.10%
Templeton Foreign Securities Fund, Class 2**	0.69%	0.21%	0.25%	1.15%  [1.16%]
PIMCO Variable Insurance Trust
PIMCO Real Return Portfolio +	0.25%	0.26%	0.15%	0.66%  [0.67%]
PIMCO Total Return Portfolio +	0.25%	0.25%	0.15%	0.65%  [0.66%]
PIMCO Emerging Markets Bond Portfolio +	0.45%	0.40%	0.15%	1.00%  [1.28%]
PIMCO High Yield Portfolio +	0.25%	0.35%	0.15%	0.75%  [0.76%]
First Eagle SoGen Variable Funds, Inc.
First Eagle SoGen Overseas Variable Fund ++	0.75%	0.50%	0.25%	1.50%  [2.08%]

*	The Fund administration fee is paid indirectly through the management fee. While the maximum amount payable under each Fund's Rule 12b-1 plan is 0.35% per year of the Fund's average daily net assets, the Fund's Board of Trustees has set the current rate at 0.25% per year.
**	The Fund's manager has agreed in advance to reduce its fee to reflect reduced services resulting from the Fund's investment in a Franklin Templeton money fund. This reduction is required by the Board and an order of the Securities and Exchange Commission.
+	PIMCO has contractually agreed to reduce total annual portfolio operating expenses to the extent such expenses would exceed, due to the payment of organization expenses and Trustees' fees, the following percentages of average daily net assets:

PIMCO Real Return Portfolio	0.65%
PIMCO Total Return Portfolio	0.65%
PIMCO Emerging Markets Bond Portfolio	1.00%
PIMCO High Yield Portfolio	0.75%

Under the Expense Limitation Agreement, PIMCO may recoup these waivers and reimbursements in future periods, not exceeding three years, provided total expenses, including such recoupment, do not exceed the annual expense limit.

++ The Adviser has agreed to waive its advisory fee and, if necessary, reimburse Fund expenses through October 31, 2002, to the extent the Fund's aggregate expenses exceed 1.50% of (annualized) average net assets. The Adviser may or may not continue this arrangement after October 31, 2002, and, if not so continued, the Fund's aggregate expenses could be greater than 1.50% of average net assets for the year. Had the 2001 expense limitation extended only through October 31, 2001, the Fund's aggregate expenses for that year would have been 1.59% of average net assets.

3. Footnote 2 that appears after the table of "Underlying Fund Annual Expenses" is hereby deleted and replaced by the following:

2. All expense figures are shown after expense reimbursements or waivers, except for the bracketed figures which show what the expense figures would have been absent reimbursement. All expense figures are based on actual expenses for the fiscal year ended December 31, 2001, except that (a) the expense figures shown for SC^SM Alger Growth Fund, SC^SM Alger Growth & Income Fund, SC^SM Alger Small Capitalization Fund, Sun Capital^SM All Cap Fund, Templeton Growth Securities Fund, Templeton Foreign Securities Fund, PIMCO Real Return Portfolio, PIMCO Real Return Portfolio, PIMCO Emerging Markets Bond Portfolio, PIMCO High Yield Portfolio, and First Eagle SoGen Overseas Variable Fund are estimates for the year 2002 and (b) certain information relating to the Lord Abbett Series Fund has been restated to reflect the fees and expenses that will be applicable during 2002 as described in note (8) below. No actual expense figures are shown for the Funds listed in (a) because each of them commenced operations in or after April of 2002, and, therefore, has less than 10 months of investment experience.

4. The examples accompanying the table of "Underlying Fund Annual Expenses" are hereby supplemented as follows:

Item 26. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE DEPOSITOR OR REGISTRANT

No person is directly or indirectly controlled by the Registrant. The Registrant is a separate account of Sun Life Assurance Company of Canada (U.S.), a wholly-owned subsidiary of Sun Life of Canada (U.S.) Holdings, Inc., a wholly-owned subsidiary of Sun Life Assurance Company of Canada - U.S. Operations Holdings, Inc., which is in turn a wholly-owned subsidiary of Sun Life Assurance Company of Canada.

The organization chart of Sun Life Assurance Company of Canada is filed as Exhibit 16 to Pre-Effective Amendment No. 1 to the Registration Statement on Form N-4, File No. 333-74844, filed February 14, 2002.

None of the companies listed in such Exhibit 16 is a subsidiary of the Registrant; therefore, the only financial statements being filed are those of Sun Life Assurance Company of Canada (U.S.).

Item 28. INDEMNIFICATION

Pursuant to Section 145 of the Delaware Corporation Law, Article 8 of the By-laws of Sun Life Assurance Company of Canada (U.S.), as amended effective as of January 1, 2000 (a copy of which was filed as Exhibit 6(b) to Pre-Effective Amendment No. 1 to Registrant's Registration Statement on Form N-4, File No. 333-30844) provides for the indemnification of directors, officers and employees of Sun Life Assurance Company of Canada (U.S.).

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Sun Life Assurance Company of Canada (U.S.) pursuant to the certificate of incorporation, by-laws, or otherwise, Sun Life (U.S.) 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 Sun Life (U.S.) of expenses incurred or paid by a director, officer, controlling person of Sun Life (U.S.) 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, Sun Life (U.S.) will submit to a court of appropriate jurisdiction the question whether such indemnification by them is against public policy as expressed in the Act, unless in the opinion of their counsel the matter has been settled by controlling precedent, and will be governed by the final adjudication of such issue.
