ENDORSEMENT
The Contract and Certificate are endorsed as outlined below.
In the SPECIFICATIONS section on page 2, the section entitled GUARANTEED
INTEREST RATE is corrected to read:
There is a guaranteed interest rate for Purchase Payment(s) held in the
Fixed Plus Account (See 1.14) and the GA Account (See 1.15).
All references in the Contract and Certificate to the "Aetna Processing Office"
are changed to "Aetna Service Center".
In PART 1. GENERAL DEFINITIONS
Add the following definitions:
DOLLAR COST AVERAGING - A program which allows a Participant to
systematically transfer amounts from the Aetna money market fund under the
Contract to the Fixed Plus Account, the Guaranteed Accumulation Account
and/or one or more of the Funds held by the Separate Account. Amounts may
be transferred out of existing funds into the Aetna money market fund under
the Contract. Amounts transferred to or from the Fixed Plus Account and
subsequently surrendered during the accumulation period will be subject to
the Fixed Plus Account transfer and partial surrender restrictions
described in the Contract. Amounts transferred from the Guaranteed
Accumulation Account Guaranteed Term before the end of that Guaranteed Term
may be subject to a Market Value Adjustment. Aetna reserves the right to
change terms and conditions for Dollar Cost Averaging upon notification to
the Contract Holder and Participants. To elect to participate in Dollar
Cost Averaging, Participants should contact the Aetna Service Center. This
program is not available to Participants in the Account Rebalancing
program.
ACCOUNT REBALANCING - A program which allows Participants to reallocate
their Individual Account values to match the investment allocations
originally selected. Only account values invested in the Separate Account
(excluding GET) are eligible to be rebalanced. Account values invested in
the Guaranteed Accumulation Account and the Fixed Plus Account are not
eligible to be rebalanced. Transfers made under this program will not be
subject to the annual transfer limits imposed by the Contract. To elect to
participate in Account Rebalancing, Participants should contact the Aetna
Service Center. This program is not available to Participants in the Dollar
Cost Averaging program.
Replace the definition of NONUNITIZED SEPARATE ACCOUNT with the following
definition:
A separate account, set up by Aetna under Title 38, Section 38a-433 of the
Connecticut General Statutes, that holds assets for GA Account Guaranteed
Terms of more than three years and, on and after September 1, 1998, amounts
allocated or transferred to Guaranteed Terms of three years or less. There
are no discrete units for this Account. The Contract Holder or Participant,
as applicable, does not participate in the investment gain or loss from
assets held in the Nonunitized Separate Account. Such gain or loss is borne
entirely by Aetna. The assets of the Nonunitized Separate Account, to the
extent of reserves and other contract liabilities, may not be charged with
other Aetna liabilities.
Amounts allocated to a Guaranteed Term of three years or less prior to
September 1, 1998, will remain in the General Account as provided by
Section 1.17, and will remain in the General Account until the applicable
Guaranteed Term's Maturity Date. If such amounts are reinvested on such
Maturity Date, such amounts will be reinvested in a Guaranteed Term in the
Nonunitized Separate Account.

Replace the definition of PURCHASE PAYMENT(S) with the following definition:
Payments received by Aetna at the Aetna Service Center for current contributions
under the Plan, as well as transferred amounts of 401(a) funds under the Plan
from other investment providers. In PART III. PURCHASE PAYMENT, CURRENT VALUE,
AND SURRENDER PROVISIONS, the section entitled INDIVIDUAL ACCOUNT(S) is revised
to read:
This Contract is issued to the Contract Holder. However, Aetna will
maintain two Individual Accounts for each Participant. These are:
(a) An Employer Account: This Individual Account will be credited with
employer Net Purchase Payments and transferred amounts of 401(a)
funds, attributable to employer contributions, from other investment
providers; and
(b) An Employee Account: This Individual Account will be credited with
employee Net Purchase Payments, specifically amounts subject to Code
Section 414(h) and transferred amounts of 401(a) funds, attributable
to 414(h) contributions from other investment providers.
Replace (c) of the section entitled NET RETURN FACTOR(S) - SEPARATE ACCOUNT with
the following:
Minus a daily actuarial charge at an annual rate that will not exceed 1.25%
for Annuity mortality and expense risks and profit and a daily
administrative charge that will not exceed 0.25% on an annual basis. The
administrative charge may be changed annually except for amounts that have
been used to purchase an Annuity.
Endorsed and made part of the Contract or Certificate on February 1, 2001, or on
the Effective Date of the Contract or Certificate, if later.
