* Effective September 1, 1999, the management fee rates for the Select
Aggressive Growth Fund and Select Capital Appreciation Fund were revised. The
Management Fee and Total Fund Expense ratios shown in the table above have been
adjusted to assume that the revised rates took effect January 1, 1999.

(1) Until further notice, Allmerica Financial Investment Management Services,
Inc. ("AFIMS") has declared a voluntary expense limitation of 1.50% of average
net assets for Select International Equity Fund, 1.35% for Select Aggressive
Growth Fund and Select Capital Appreciation Fund, 1.25% for Select Value
Opportunity Fund, 1.20% for Select Growth Fund and Core Equity Fund, 1.10% for
Select Growth and Income Fund, 1.00% for Select Investment Grade Income Fund and
Government Bond Fund, and 0.60% for Equity Index Fund and Money Market Fund. The
total operating expenses of these Funds of AIT were less than their respective
expense limitations throughout 1999.

<PAGE>

Until further notice, AFIMS has declared a voluntary expense limitation of 1.20%
of average daily net assets for the Select Strategic Growth Fund. In addition,
AFIMS has agreed to voluntarily waive its management fee to the extent that
expenses of the Select Emerging Markets Fund exceed 2.00% of the Fund's average
daily net assets, except that such waiver shall not exceed the net amount of
management fees earned by AFIMS from the Fund after subtracting fees paid by
AFIMS to a sub-advisor.

Until further notice, the Select Value Opportunity Fund's management fee rate
has been voluntarily limited to an annual rate of 0.90% of average daily net
assets, and total expenses are limited to 1.25% of average daily net assets.

The declaration of a voluntary management fee or expense limitation in any year
does not bind AFIMS to declare future expense limitations with respect to these
Funds. These limitations may be terminated at any time.

(2) These Funds have entered into agreements with brokers whereby the brokers
rebate a portion of commissions. These amounts have been treated as reductions
of expenses. Including these reductions to the operating expenses, total annual
fund operating expenses were 1.88% for the Select Emerging Markets Fund, 1.01%
for Select International Equity Fund, 0.84% for Select Aggressive Growth Fund,
0.88% for Select Value Opportunity Fund, 0.81% for Select Growth Fund, 1.17% for
Select Strategic Growth Fund, 0.45% for Core Equity Fund, and 0.73% for Select
Growth and Income Fund.

(3) Had there been no fee waivers or expense reimbursements, the Management Fee,
Other Expenses and Total Fund Expenses of the AIM V.I. Aggressive Growth Fund
would have been 0.80%, 1.62% and 2.42%, respectively.

(4) Service Class inception is May 1, 2000. Fees and Expenses shown are based on
those for the Standard Class. The investment advisor for the DGPF Growth
Opportunities Series is Delaware Management Company ("Delaware Management").
Effective May 1, 2000 through October 31, 2000, the investment advisor has
voluntarily agreed to waive its management fee and reimburse the Series for
expenses to the extent that total expenses, exclusive of 12b-1 fees, will not
exceed 0.85%. The declaration of a voluntary expense limitation does not bind
Delaware Management to declare future expense limitations with respect to this
Series.

(5) The investment adviser for the DGPF International Equity Series is Delaware
International Advisers Ltd. ("Delaware International"). Effective May 1, 2000
through October 31, 2000, Delaware International has agreed voluntarily to waive
its management fee and reimburse the Series for expenses to the extent that
total expenses will not exceed 0.95%. This limitation replaces a prior
limitation of 0.95% that expired on April 30, 2000. The fee ratios shown above
have been restated, if necessary, to reflect the new voluntary limitation which
took effect on May 1, 2000. The declaration of a voluntary expense limitation
does not bind Delaware International to declare future expense limitations with
respect to this Series. For the fiscal year ended December 31, 1999, before
waiver and/or reimbursement by Delaware International, total fund expenses as a
percentage of average daily net assets were 0.97%.

(6) A portion of the brokerage commissions that certain funds paid was used to
reduce fund expenses. In addition, through arrangements with certain funds', or
Fidelity Management & Research Company on behalf of certain funds', custodian
credits realized as a result of uninvested cash balances were used to reduce a
portion of the fund's expenses. Including these reductions, total operating
expenses presented in the table would have been 0.87% for the Fidelity VIP
Overseas Portfolio; 0.65% for the Fidelity VIP Growth Portfolio; 0.56% for the
Fidelity VIP Equity-Income Portfolio and 0.62% for the Fidelity VIP II Asset
Manager Portfolio.

(7) Service Class 2 expenses are based on the estimated expenses for the first
year.

<PAGE>

(8) The Funds' Class 2 distribution plan or "rule 12b-1 plan" is described in
the Funds' prospectus. The fund administration fee of the Franklin Natural
Resources Securities Fund is paid indirectly through the management fee. The
Franklin Small Cap Fund pays for similar services directly.

(9) On 2/8/00, a merger and reorganization was approved that combined the assets
of the Franklin Small Cap Fund with a similar fund of the Templeton Variable
Products Series Fund, effective 5/1/00. On 2/8/00, fund shareholders approved
new management fees, which apply to the combined fund effective 5/1/00. The
table shows restated total expenses based on the new fees and assets of the fund
as of 12/31/99, and not the assets of the combined fund. However, if the table
reflected both the new fees and the combined assets, the fund's expenses after
5/1/00 would be estimated to be the same.

(10) The Fund's actual Total Annual Fund Operating Expenses were lower than the
figures shown because its custodian fees were reduced under an expense offset
arrangement. Including the reduction for the expense offset arrangement and
voluntary expense waiver, the Fund's Management Fees, Other Expenses and Total
Fund Expenses would have been 0.75%, 0.50% and 1.25% respectively. Certain
expenses of the Fund were absorbed voluntarily by INVESCO in order to ensure
that expenses for the Fund did not exceed 1.25% of the Fund's average net
expenses pursuant to a commitment between the Fund and INVESCO. This commitment
may be changed at any time following consultation with the board of directors.
The Fund's Management Fees, Other Expenses and Total Fund Expenses for the
fiscal year ended December 31, 1999, excluding any voluntary expense waiver and
expense offset arrangements, would have been 0.75%, 2.11% and 2.86%
respectively.

(11) Expenses are based on the estimated expenses that the new Service Shares
Class of each Portfolio expects to incur in its initial fiscal year.

(12) Pursuant to their respective agreements with KVS, the investment manager
and the accounting agent have agreed, for the one year period commencing on May
1, 2000, to limit their respective fees and to reimburse other expenses to the
extent necessary to limit total operating expenses of the KVS Dreman Financial
Services and the Kemper Technology Growth Portfolios to the amounts set forth in
the Total Fund Expenses column of the table above. Without taking into effect
these expense caps, for the KVS Dreman Financial Services and the Kemper
Technology Growth Portfolios of KVS, management fees are estimated to be 0.75%
and 0.75%, respectively. Other expenses are estimated to be 0.44% and 0.29%,
respectively; and total operating expenses would have been 1.19% and 1.04%,
respectively.

(13) The Kemper Technology Growth Portfolio commenced operations on May 1, 1999,
therefore "other expenses" are annualized. Actual expenses may be greater or
less than shown.

(14) Class II shares of the Pioneer Emerging Markets VCT Portfolio and Pioneer
Real Estate Growth VCT Portfolio commenced operations on May 1, 2000; therefore,
expenses shown are estimated and annualized.

(15) Fees and expenses reflect waivers/reimbursements currently applicable to
the portfolios. As of May 1, 2000, Pioneer Investment Management, Inc. has
agreed voluntarily to limit its management fee and, if necessary, to limit other
operating expenses of Class I shares of the Pioneer Emerging Markets VCT
Portfolio and the Pioneer Real Estate Growth VCT Portfolio to 1.75% and 1.25%,
respectively, of the average daily net assets attributable to Class I shares.
The portion of portfolio expenses attributable to Class II shares will be
reduced only to the extent such expenses are reduced for Class I shares. This
agreement is voluntary and temporary and may be revised or terminated at any
time.

The Underlying Fund information above was provided by the Underlying Funds and
was not independently verified by the Company.

EXPENSE EXAMPLES: The following examples demonstrate the cumulative expenses,
which an Owner of ExecAnnuity '93 (A3021-93) would pay at 1-year, 3-year, 5-year
and 10-year intervals under certain contingencies. Each example assumes a $1,000
investment in a Sub-Account and a 5% annual return on assets and assumes that
the Underlying Fund expenses listed above remain the same in each of the 1, 3, 5
and 10-year intervals. As required by rules of the Securities and Exchange
Commission (the "SEC"), the Policy fee is reflected in the examples by a method
designed to show the "average" impact of the Policy fee on an investment in the
Separate Account. The total Policy fees collected under the Policies by the
Company are divided by the total average net assets attributable to the
Policies. The resulting percentage is 0.05%, and the amount of the Policy fee is
assumed to be $0.50 in the examples. The Policy fee is only deducted when the
Accumulated Value is less than $50,000. Lower costs apply to Policies issued and
maintained as part of a 401(k) plan. Because the expenses of the Underlying
Funds differ, separate examples are used to illustrate the expenses incurred by
an Owner on an investment in the various Sub-Accounts. Owners of ExecAnnuity '91
(A3018-91 and A3018-94) should review the expenses examples in Appendix B.)

THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

(1)(a) If, at the end of the applicable time period, you surrender your Policy
or annuitize* under any period certain option, you would pay the following
expenses on a $1,000 investment, assuming a 5% annual return on assets and no
Rider:**

more of the Funds of AIT. Under each Sub-Adviser agreement, the Sub-Adviser is

AFIMS and the Trustees instructions. AFIMS is solely responsible for the payment
of all fees for investment management services to the Sub-Advisers. The

Agreement, AIT bears all expenses incurred in its operation including fees and

Equity Fund is invested in common stocks and securities convertible into common
stocks that are believed to represent significant underlying value in relation
to current market prices.

AIT EQUITY INDEX FUND -- seeks to provide investment results that correspond to
the aggregate price and yield performance of a representative selection of

Composite Index of 500 Stocks.

preservation of capital and liquidity. The Money Market Fund is invested in a

AIT SELECT AGGRESSIVE GROWTH FUND - seeks above-average capital appreciation by
investing primarily in common stocks of companies which are believed to have
significant potential for capital appreciation.

AIT SELECT CAPITAL APPRECIATION FUND - seeks long-term growth of capital.
Realization of income is not a significant investment consideration and any

objective. The Fund will invest primarily in common stock of industries and

services, and which operate in a favorable competitive environment and
regulatory climate.

income by investing primarily in high-yielding, lower-rated fixed-income

rating. For more information about these lower-rated securities, see the

(1) Until further notice, Allmerica Financial Investment Management Services,
Inc. ("AFIMS") has declared a voluntary expense limitation of 1.50% of average
net assets for Select International Equity Fund, 1.35% for Select Aggressive
Growth Fund and Select Capital Appreciation Fund, 1.25% for Select Value
Opportunity Fund, 1.20% for Select Growth Fund and Core Equity Fund, 1.10% for
Select Growth and Income Fund, 1.00% for Select Investment Grade Income Fund and
Government Bond Fund, and 0.60% for Equity Index Fund and Money Market Fund. The
total operating expenses of these Funds of the Trust were less than their
respective expense limitations throughout 1999.

Until further notice, AFIMS has declared a voluntary expense limitation of 1.20%
of average daily net assets for the Select Strategic Growth Fund. In addition,
AFIMS has agreed to voluntarily

3
<PAGE>

waive its management fee to the extent that expenses of the Select Emerging
Markets Fund exceed 2.00% of the Fund's average daily net assets, except that
such waiver shall not exceed the net amount of management fees earned by AFIMS
from the Fund after subtracting fees paid by AFIMS to a sub-advisor.

(7) Service Class 2 expenses are based on the estimated expenses for the first
year.

4
<PAGE>

(11) Expenses are based on the estimated expenses that the new Service Shares
Class of each Portfolio expects to incur in its initial fiscal year.

(13) The Kemper Technology Growth Portfolio commenced operations on May 1, 1999,
therefore "other expenses" are annualized. Actual expenses may be greater or
less than shown.

The Underlying Fund information above was provided by the Underlying Funds and
was not independently verified by the Company.

<PAGE>

EXPENSE EXAMPLES: The following examples demonstrate the cumulative expenses
which an Owner would pay at 1-year, 3-year, 5-year and 10-year intervals under
certain contingencies. Each example assumes a $1,000 investment in a Sub-Account
and a 5% annual return on assets and assumes that the Underlying Fund expenses
listed above remain the same in each of the 1, 3, 5 and 10-year intervals. As
required by rules of the Securities and Exchange Commission (the "SEC"), the
Contract fee is reflected in the examples by a method designed to show the
"average" impact of the Contract Fee on an investment in the Variable Account.
The total Contract fees collected under the Contracts by the Company are divided
by the total average net assets attributable to the Contracts. The resulting
percentage is 0.05%, and the amount of the Contract fee is assumed to be $0.50
in the examples. The Contract fee is only deducted when the Accumulated Value is
less than $50,000. Lower costs apply to Contracts issued and maintained as part
of a 401(k) plan. Because the expenses of the Underlying Funds differ, separate
examples are used to illustrate the expenses incurred by an Owner on an
investment in the various Sub-Accounts.

THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

(1)(a) If, at the end of the applicable time period, you surrender your Contract
or annuitize* under any commutable period certain option or a noncommutable
fixed period certain option of less than ten years, you would pay the following
expenses on a $1,000 investment, assuming a 5% annual return on assets and no
Riders:**

(c) As indicated in Part B (Statement of Additional Information) in
response to Item 20(c), there were no commissions retained by Allmerica
Investments, Inc., the principal underwriter of the Contracts, for sales of
variable contracts funded by the Registrant in 1999. No other commissions
or other compensation was received by the principal underwriter, directly
or indirectly, from the Registrant during the Registrant's last fiscal
year.

ITEM 30. LOCATION OF ACCOUNTS AND RECORDS

Each account, book or other document required to be maintained by Section
31(a) of the 1940 Act and Rules 31a-1 to 31a-3 thereunder are maintained by
the Company at 440 Lincoln Street, Worcester, Massachusetts.

ITEM 31. MANAGEMENT SERVICES

The Company provides daily unit value calculations and related services for
the Company's separate accounts.

ITEM 32. UNDERTAKINGS

(a) The Registrant hereby undertakes to file a post-effective amendment to
this registration statement as frequently as is necessary to ensure
that the audited financial statements in the registration statement
are never more than 16 months old for so long as payments under the
variable annuity contracts may be accepted.

(b) The Registrant hereby undertakes to include in the prospectus a
postcard that the applicant can remove to send for a Statement of
Additional Information.

(c) The Registrant hereby undertakes to deliver a Statement of Additional
Information and any financial statements promptly upon written or oral
request, according to the requirements of Form N-4.

(d) Insofar as indemnification for liability arising under the 1933 Act
may be permitted to Directors, Officers and Controlling Persons of
Registrant under any registration statement, underwriting agreement or
otherwise, Registrant has been advised that, in the opinion of the
SEC, such indemnification is against public policy as expressed in the
1933 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 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,
Registrant will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of

<PAGE>

appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the 1933 Act and will be
governed by the final adjudication of such issue.

(e) The Company hereby represents that the aggregate fees and charges
under the Policies are reasonable in relation to the services
rendered, expenses expected to be incurred, and risks assumed by the
Company.

ITEM 33. REPRESENTATIONS CONCERNING WITHDRAWAL RESTRICTIONS ON SECTION 403(b)
PLANS AND UNDER THE TEXAS OPTIONAL RETIREMENT PROGRAM

Registrant, a separate account of First Allmerica Financial Life Insurance
Company ("Company"), states that it is (a) relying on Rule 6c-7 under the 1940
Act with respect to withdrawal restrictions under the Texas Optional Retirement
Program ("Program") and (b) relying on the "no-action" letter (Ref. No. IP-6-88)
issued on November 28, 1988 to the American Council of Life Insurance, in
applying the withdrawal restrictions of Internal Revenue Code Section
403(b)(11). Registrant has taken the following steps in reliance on the letter:

1. Appropriate disclosures regarding the redemption/withdrawal
restrictions imposed by the Program and by Section 403(b)(11) have
been included in the prospectus of each registration statement used in
connection with the offer of the Company's variable contracts.

2. Appropriate disclosures regarding the redemption/withdrawal
restrictions imposed by the Program and by Section 403(b)(11) have
been included in sales literature used in connection with the offer of
the Company's variable contracts.

3. Sales Representatives who solicit participants to purchase the
variable contracts have been instructed to specifically bring the
redemption/withdrawal restrictions imposed by the Program and by
Section 403(b)(11) to the attention of potential participants.

4. A signed statement acknowledging the participant's understanding of
(i) the restrictions on redemption/withdrawal imposed by the Program
and by Section 403(b)(11) and (ii) the investment alternatives
available under the employer's arrangement will be obtained from each
participant who purchases a variable annuity contract prior to or at
the time of purchase.

Registrant hereby represents that it will not act to deny or limit a transfer
request except to the extent that a Service-Ruling or written opinion of
counsel, specifically addressing the fact pattern involved and taking into
account the terms of the applicable employer plan, determines that denial or
limitation is necessary for the variable annuity contracts to meet the
requirements of the Program or of Section 403(b). Any transfer request not so
denied or limited will be effected as expeditiously as possible.
