                       MML BAY STATE LIFE INSURANCE COMPANY
              OPPENHEIMERFUNDS LIFETRUST VARIABLE ANNUITY CONTRACT
                MML BAY STATE VARIABLE ANNUITY SEPARATE ACCOUNT 1
    
                                   May 1, 1998      

This prospectus (the "Prospectus") describes a flexible purchase payment
individual variable annuity contract (the "Contract") issued by MML Bay State
Life Insurance Company ("MML Bay State"). The Contract provides for the
accumulation of contract values prior to maturity and for the distribution of
annuity benefits thereafter.
    
Purchase payments may be allocated among the fourteen Divisions (subject to
state availability) of MML Bay State Variable Annuity Separate Account 1 (the
"Separate Account"), and, in the majority of states, a Fixed Account with a
Market Value Adjustment feature (the "Fixed Account"). Purchase payments
allocated to a Division of the Separate Account will be invested in a
corresponding fund (a "Fund") of either MML Series Investment Fund (the "MML
Trust") or Oppenheimer Variable Account Funds (the "Oppenheimer Trust"
collectively MML Trust and Oppenheimer Trust are referred to as the "Trusts").
The MML Trust is a no-load, open-end management investment company and the
Oppenheimer Trust is a diversified open-end investment company. The Prospectus
for MML Trust, which is attached to this Prospectus, describes the investment
objectives and risks of investing in the four available MML Funds: MML Equity
Fund; MML Money Market Fund; MML Managed Bond Fund; and MML Blend Fund.
Similarly, the Prospectus for the Oppenheimer Trust describes the investment
objectives and risks of investing in the ten available Oppenheimer Funds:
Oppenheimer Money Fund; Oppenheimer High Income Fund; Oppenheimer Bond Fund;
Oppenheimer Aggressive Growth Fund (Prior to May 1, 1998, this Fund was named
Oppenheimer Capital Appreciation Fund.); Oppenheimer Growth Fund; Oppenheimer
Multiple Strategies Fund; Oppenheimer Global Securities Fund; Oppenheimer
Strategic Bond Fund; Oppenheimer Growth & Income Fund, and subject to state
availability, Oppenheimer Small Cap Growth Fund.      

Annuity benefits can be either fixed or variable amounts or a combination of
both. The Contract value prior to maturity, except for amounts allocated to the
Fixed Account, and the amount of any variable annuity payments thereafter will
vary with the investment performance of the Funds which You have selected. MML
Bay State serves as depositor for the Separate Account.
    
This Prospectus sets forth the information that a prospective investor ought to
know before investing. Certain additional information about the Contract is
contained in a Statement of Additional Information dated May 1, 1998, which has
been filed with the Securities and Exchange Commission and is incorporated
herein by reference. The Statement of Additional Information is available upon
written or oral (call 1-800-258-4511) request and without charge from the
Service Center.      
    
The Securities and Exchange Commission (SEC) maintains a Web site
(http://www.sec.gov) that contains the Statement of Additional Information,
material incorporated by reference and other information regarding registrants
that is filed with the SEC electronically.      
    
THIS PROSPECTUS MUST BE ACCOMPANIED BY OR PRECEDED BY THE PROSPECTUSES OF BOTH
THE OPPENHEIMER VARIABLE ACCOUNT FUNDS AND THE MML SERIES INVESTMENT FUND, WHICH
ARE ATTACHED HERETO. ADDITIONALLY, IN STATES WHERE THE FIXED ACCOUNT IS OFFERED,
THIS PROSPECTUS MUST ALSO BE ACCOMPANIED BY A PROSPECTUS FOR THE FIXED ACCOUNT.

birthday and 0% thereafter, but not more than two times the difference between
all purchase payments and all redemptions; or (b) the Accumulated Value of the
Contract less any applicable Administrative Charge (and any Sales Charge, if the
Annuitant's age on the Contract Date exceeds 75).

If the Contract Owner dies prior to the Maturity Date, the named beneficiary
will receive the Cash Redemption Value of the Contract.

Please note that in some states, the Death Benefit described above may not be
available. For more information concerning the available death benefits see The
Death Benefit

TAX TREATMENT
    
Under current law, during the accumulation phase of the Contract, the Contract's
Accumulated Value is not taxed. If redemptions are made from the Contract prior
to age 59 1/2, a ten percent (10%) federal income tax penalty will apply to the
income portion of the withdrawal. In certain instances, the tax penalty will not
apply. Please review Taxation of Contracts in General, for a more detailed
description of the tax rules applicable to the Contract. Partial or full
redemption of a Contract may require MML Bay State to withhold 20% of the amount
redeemed, as more fully described in the Taxation of Qualified Plans, TSAs and
IRAs.      

RIGHT TO RETURN CONTRACT

The Contract entitles the purchaser to a 10-day revocation right more fully
described under Right to Return Contracts.

CHARGES UNDER THE CONTRACT

MML Bay State assesses certain charges for the administration and the mortality
and expense risks associated with the Contract. MML Bay State also assesses a
contingent deferred sales charge (the "Sales Charge") if all or some of the
value is redeemed prior to the expiration of a seven-year period following the
date of each purchase payment.

Each Contract Year, MML Bay State permits You to redeem, without a Sales Charge,
up to 10% of the Contract's premiums that would otherwise be assessed a Sales
Charge. For more information concerning this feature, please consult Contingent
Deferred Sales Charge.

ASSET CHARGE
    
MML Bay State currently imposes a charge of 1.40% on an annual basis against the
assets held in the Separate Account. (MML Bay State reserves the right to
increase this fee to 1.50% see - Asset Charge).      

ADMINISTRATIVE CHARGE

An administrative charge, currently $30 (maximum $50) will be assessed annually
on each Contract. This charge will be waived for Contracts which have an
Accumulated Value of at least $50,000.

PREMIUM TAXES
    
Additionally, a deduction is made for premium taxes for purchase payments made
into Contracts in certain jurisdictions where such tax applies. Currently, the
applicable premium tax will be deducted at the time of redemption, death,
maturity, or annuitization. (See - Premium Taxes.)

The purpose of the table set forth above is to assist You in understanding the
various costs and expenses that Contract Owners bear directly or indirectly. The
table is based on estimated amounts for the most recent fiscal year and reflects
the expenses of the Separate Account and the Trusts, adjusted to reflect changes
in management fee rates and a voluntary expense limitation. The table does not
reflect the deduction of premium taxes.      
    
For the purpose of calculating the expenses in the above examples, we have
converted the $30 annual administrative charge to a 0.06% annual asset charge
based on an average contract size of $50,000.      

Converted in this way, this annual charge (on a percentage basis) would be
higher for smaller contracts and lower for larger contracts. No annual
Administrative Charge is assessed on contracts with accumulated values of
$50,000 or more.

The above examples should not be considered representative of past or future
expenses; actual expenses may be more or less than those shown.

Insurance Company,
The Separate Account, and
The Trusts

MML BAY STATE LIFE INSURANCE
COMPANY
    
MML Bay State Life Insurance Company ("MML Bay State") is a life insurance
company and a wholly-owned subsidiary of Massachusetts Mutual Life Insurance
Company ("MassMutual"). Organized in 1894 under the laws of the state of
Missouri, MML Bay State (formerly known as Western Life Insurance Company of
America) was purchased in 1981 by MassMutual. Its name was changed in March
1982. On June 30, 1997 MML Bay State was redomesticated from the State of
Missouri to the State of Connecticut. MML Bay State's Home Office is located in
Hartford, Connecticut.      
    
MML Bay State currently is licensed to sell variable life insurance in all
states except New York. MML Bay State plans to obtain variable annuity authority
in all states except New York, and, as of March 1, 1998, it had obtained such
authority in 45 states and the District of Columbia. The Contract is available
only in states where this approval process has been completed.      

OPPENHEIMERFUNDS, INC.
    
OppenheimerFunds, Inc. ("OFI") is a corporation organized under the laws of the
state of Colorado. It has operated as an investment adviser since April 30,
1959. It (including a subsidiary) currently advises U.S. investment companies
with assets aggregating over $75 billion as of December 31, 1997, and having
more than 3.5 million shareholder accounts. OFI is owned by Oppenheimer
Acquisition Corp., a holding company owned in part by senior management of OFI,
and ultimately controlled by MassMutual. OFI serves as investment adviser to the
Oppenheimer Trust. OFI is registered as an investment adviser under the
Investment Advisers Act of 1940.      

MASSMUTUAL
    
MassMutual is a mutual life insurance company chartered in 1851 under the laws
of Massachusetts. Its Home Office is located in Springfield, Massachusetts.
MassMutual is licensed to transact life, accident, and health insurance business
in all fifty states of the United States, the District of Columbia, Puerto Rico,

business in all states, the District of Columbia and Puerto Rico.      
    
MassMutual has estimated unconsolidated statutory assets in excess of $57
billion, and estimated total assets under management in excess of $152 billion.
     

THE SEPARATE ACCOUNT

MML Bay State Variable Annuity Separate Account 1 (the "Separate Account") was
established on January 14, 1994. It is a separate account of MML Bay State
registered with the Securities and Exchange Commission as a unit investment
trust. The Separate Account meets the definition of a Separate Account under
Rule 0-1(e) under the Investment Company Act of 1940.
    
The Separate Account is divided into Divisions. Each Division invests in
corresponding shares of either the MML Trust or the Oppenheimer Trust. The value
of both Accumulation Units and Annuity Units in each Division reflects the
investment results of its underlying Funds. Please note that MML Bay State
reserves the right to add, or substitute Divisions, create new separate
accounts, in some cases restrict Funds, and to invest in shares of other series
of the Trusts or of other registered, open-end investment companies. See --
Reservation of Rights.      

    
Although MML Bay State owns the assets of the Separate Account, assets of the
Separate Account equal to the reserves and other Contract liabilities which
depend on the investment performance of the Separate Account and are not
chargeable with liabilities arising out of any other business MML Bay State may
conduct. The income and capital gains and losses, realized or unrealized, of
each Division of the Separate Account are credited to or charged against such
Division without regard to the income and capital gains and losses of the other
Divisions or other accounts of MML Bay State. This state law provision has been
supported in several recent decisions in states reviewing this issue. All
obligations arising under a Contract, however, are general corporate obligations
of MML Bay State.      

THE TRUSTS
    
Each of the Trusts described below has separate assets and liabilities and a
separate net asset value per share. An investor's interest in a Separate Account
is limited to the Fund(s) in which shares are held. Since market risks are
inherent in all securities to varying degrees, assurance cannot be given that
the investment objective of any of the Funds will be met.      
    
Financial Statements for the Oppenheimer Trust and for the MML Trust are
contained in their respective Statements of Additional Information.      
    
Additional information concerning the investment objectives and policies of the
Funds can be found in the current prospectuses for the Trusts which are attached
to this prospectus and should be read carefully before making any decision
concerning allocation of premium payments.

INVESTMENTS AND OBJECTIVES OF
THE AVAILABLE FUNDS:

MML Equity Fund

The assets of the MML Equity Fund are invested primarily in common stocks and
other equity-type securities. The primary investment objective of the MML Equity
Fund is to achieve a superior total rate of return over an extended period of
time from both capital appreciation and current income. A secondary investment
objective is the preservation of capital when business and economic conditions
indicate that investing for defensive purposes is appropriate.

MML Money Market Fund

The assets of the MML Money Market Fund are invested in short-term debt
instruments, including but not limited to commercial paper, certificates of
deposit, bankers' acceptances, and obligations issued, sponsored, or guaranteed
by the United States government or its agencies or instrumentalities. The
investment objectives of the MML Money Market Fund are to achieve high current
income, preservation of capital, and liquidity.

MML Managed Bond Fund
    
The assets of the MML Managed Bond Fund are invested primarily in publicly
issued, readily marketable, fixed income securities of such maturities as
MassMutual, as investment manager, deems appropriate from time to time in light
of market conditions and prospects. The investment objective of the MML Managed
Bond Fund is to achieve as high a total rate of return on an annual basis as is
considered consistent with the preservation of capital values.      

MML Blend Fund
    
The assets of the MML Blend Fund are invested in a portfolio of common stocks
and other equity-type securities, bonds and other debt securities with
maturities generally exceeding one year, and money market instruments and other
debt securities with maturities generally not exceeding one year. The investment
objective of the MML Blend Fund is to achieve as high a level of total rate of
return over an extended period of time as is considered consistent with prudent
investment risk and the preservation of capital values.      
    
Oppenheimer Money Fund      
    
Oppenheimer Money Fund seeks the maximum current income from investments in
"money market" securities consistent with low capital risk and maintenance of
liquidity. Its shares are neither insured nor guaranteed by the U.S. Government,
and there is no assurance that this Fund will be able to maintain a stable net
asset value of $1.00 per share.      

Oppenheimer High Income Fund

Oppenheimer High Income Fund seeks a high level of current income from
investment in high yield, high-risk, fixed-income securities, including unrated
securities or securities in the lower rating categories. These securities may be
considered to be speculative. Please consult the Oppenheimer Trust prospectus
for a more complete discussion of the risks and investment objectives associated
with this Fund.

Oppenheimer Bond Fund
    
Oppenheimer Bond Fund primarily seeks a high level of current income by
investing primarily in debt securities. Secondarily, the Fund seeks capital
growth when consistent with its primary objective.      
    
Oppenheimer Aggressive Growth Fund*      
    
Oppenheimer Aggressive Growth Fund seeks to achieve capital appreciation by
investing in "growth-type" companies.

<PAGE>
 
by investing in securities of well-known established companies.

Oppenheimer Multiple Strategies Fund

includes current income and capital appreciation in the value of its shares)
from investments in common stocks and other equity securities, bonds and other
debt securities, and "money market" securities.

Oppenheimer Global Securities Fund
    
Oppenheimer Global Securities Fund seeks long-term capital appreciation by
investing a substantial portion of assets in securities of foreign issuers,
"growth-type" companies, cyclical industries and special situations which are
considered to have appreciation possibilities. Current income is not an
objective. This Fund's investments may be considered to be speculative. Please
consult the Oppenheimer Trust prospectus for a more complete discussion of the
risks and investment objectives associated with this Fund.      

Oppenheimer Strategic Bond Fund

Oppenheimer Strategic Bond Fund seeks a high level of current income principally
derived from interest on debt securities and seeks to enhance such income by
writing covered call options on debt securities. The Fund invests principally
in: (i) foreign government and corporate debt securities; (ii) U.S. Government
securities; and (iii) lower-rated high yield, high-risk debt securities. This
Fund's investments may be considered to be speculative. Please consult the
Oppenheimer Trust prospectus for a more complete discussion of the risks and
investment objectives associated with this Fund.

Oppenheimer Growth & Income Fund

Oppenheimer Growth & Income Fund seeks a high total return (which includes
growth in the value of its shares as well as current income) from equity and
debt securities. From time to time this Fund may focus on small to medium
capitalization common stocks, bonds and convertible securities.
    
Oppenheimer Small Cap Growth Fund*      
    
Oppenheimer Small Cap Growth Fund seeks capital appreciation. Current income is
not an objective. In seeking its objective, the Fund emphasizes investments in
securities of "growth-type" companies with market capitalization less than $1
billion, including common stocks, preferred stocks, convertible securities,
rights warrants and options, in proportions which may vary from time to time.
     
    
*Subject to state availability      
    
All dividends and capital gains distributions paid by the Funds' shares are
automatically reinvested in additional shares at their net asset value
determined on the distribution date.      
    
An Explanation of the Contract      
    
The principal provisions of the Contract are described below. If You desire
additional information, You should refer to the Contract and to the Statement of
Additional Information. For a complete understanding of Your rights, You should
also review any applicable employee benefit plan documents.      

GENERAL-USES OF THE CONTRACT

The Contract described herein is an individual variable annuity contract issued
by MML Bay State. Purchase payments are flexible. The Contract may be purchased
by individuals or entities for use in arrangements not receiving favorable tax
treatment under the Internal Revenue Code.
    
The Contract is also available for use in the following retirement plans which
qualify (with necessary endorsement as appropriate) for special federal tax
treatment under the Internal Revenue Code of 1986, as amended (the "Code"): (1)
pension and profit-sharing plans qualified under Section 401(a) or 403(a) of the
Code ("Qualified Plans"), which may also constitute participant-directed
individual account plans under Section 404(c) of ERISA; (2) annuity purchase
plans adopted by public school systems and certain tax-exempt organizations
pursuant to Section 403(b) of the Code ("Tax Sheltered Annuities" or "TSAs");
and (3) Individual Retirement Annuities established in accordance with Section
408 of the Code ("IRAs"), including those established by employer contributions
under a Simplified Employee Pension Plan arrangement. MML Bay State also may
make this Contract available in the Roth IRA market. The section of this
prospectus, Taxation of Qualified Plans, TSAs and IRAs, includes information on
Roth IRAs. At MML Bay State's request, the Internal Revenue Service has issued
to MML Bay State favorable opinion letters approving specific versions of the
Contract. IRA Contract Owners with these Contracts will receive a copy of the
favorable opinion letter. The Internal Revenue Service approval is a
determination only as to the form of the Contract for use as an IRA and does not
represent a determination of the merits of the Contract as an IRA. Under
tax-qualified retirement plans except TSAs and IRAs, participants may not be the
Contract Owners and, therefore, may have no Contract Owners' rights.      
    
Unless restricted by endorsement or the terms of the Contract, the Contract
Owner has all rights in the Contract prior to the Maturity Date, including the
right to make a partial or full redemption of the Contract, to designate and
change the beneficiaries who will receive the proceeds at the death of the
Annuitant or Contract Owner before the Maturity Date, to transfer amounts among
the Divisions of the Separate Account (and to and from the Fixed Account, if
available) and to designate a payment option to begin on the Maturity Date.
Prior to issue, a Contract will be endorsed to preclude the Contract Owner from
assigning the Contract as collateral. Although both Owner and the Joint Owner
must authorize any change made to the Contract, either the Owner or Joint Owner
may exercise certain Contract rights with the consent, satisfactory to us, of
the other.      


                                      12
<PAGE>
 
The Contract Owner may, subject to certain limitations, be the Annuitant or
another individual or entity.

The Accumulation (Pay-In) Period

HOW CONTRACTS MAY BE PURCHASED

The minimum initial purchase payment is $2,000. After making Your initial
payment, You may make as many or as few subsequent purchase payments of at least
$100 as You desire. The Contract permits MML Bay State to establish a maximum on
total purchase payments that may be made under the Contract. This maximum is
$1,000,000 without prior Home Office approval.

INITIAL PURCHASE

You may place Your initial purchase payment, together with a completed
Application, with Your registered representative.

SUBSEQUENT PURCHASES

You may make subsequent purchase payments by mailing Your check, clearly
indicating Your name and Contract Number, to the Service Center.

WIRE TRANSFER

You may make purchase payments by wire transfer. For instructions concerning how
to make a wire transfer, please contact the Service Center.

ELECTRONIC DATA TRANSMISSION OF
APPLICATION INFORMATION
    
MML Bay State may accept, by agreement with a limited number of broker-dealers,
electronic data transmission of Application information, along with wire
transmittals of initial purchase payments from the broker-dealers to the Service
Center for purchase of the Contract. The Contract Owner must sign the
Application prior to exercising any ownership rights in the Contract. Please
contact the Service Center to receive more information about electronic data
transmission of Application information.      

ALLOCATION OF PURCHASE PAYMENTS

You may direct that Your purchase payments (after deducting any applicable
premium taxes) be allocated among the Divisions of the Separate Account.
Additionally, where available, and subject to minimum allocations of $1,000,
purchase payments may be allocated to Segments of the Fixed Account. Initial
purchase payment allocations to either a Division of the Separate Account or to
a Segment will be effective as of the Valuation Date within two business days of
the date an initial purchase payment is received in good order at the Service
Center provided that Your Contract application is complete. If an initial
purchase payment is not applied within five business days after receipt (due to
incomplete or ambiguous application information, for example), the payment
amount will be refunded unless specific consent to retain the payment for a
longer period is obtained from the prospective purchaser. Purchase payments
allocated to a Division will be applied to purchase Accumulation Units in that
Division at its Accumulation Unit value on the Valuation Date. These
Accumulation Units will be used in determining the value of amounts held in a
Division of a Separate Account credited to a Contract on or prior to the
Maturity Date. The value of the Accumulation Units in each Division will vary
with and will reflect the investment performance of that Division (which in turn
will reflect the investment performance and expenses of the Fund in which the
assets of that Division are invested), less any applicable taxes and the
applicable Asset Charge. A more detailed description of how the value of an
Accumulation Unit is calculated is contained in the Statement of Additional
Information.

MML Bay State will credit to your Contract subsequent purchase payments as of
the day received in good order, provided that the payment is received prior to
that day's Valuation Time. If received after that day's Valuation Time or on a
day that is not a Valuation Day (e.g., a day when the New York Stock Exchange is
closed), MML Bay State will credit the payment to your account as of the next
Valuation Date.

GENERAL TRANSFER RULES

Prior to 30 days before the Maturity Date, the Contract Owner may make transfers
among Divisions of the Separate Account (and if available among Segments of the
Fixed Account) without the imposition of a transfer fee. If more than four
transfers have been made in a Contract Year, MML Bay State reserves the right to
deduct a transfer fee of $20. Currently 14 transfers may be made per Contract
Year without charge. (Transfers made by Dollar Cost Averaging do not count
against the 14 transfer limit.)

If a Variable Monthly Income is in effect, transfers among the Divisions of the
Separate Account are limited to one transfer every three months.
    
All transfers, whether occurring before or after the Maturity Date are subject
to the following:      

   (a) The minimum amount which may be transferred is the lesser of: (1) $500;
       or (2) the Accumulated Value in the Division or the Accumulated Amount in
       a Segment.

   (b) Transfers will be effected as of the Valuation Date which is on or next
       follows the date Your request is received in good order at the Service
       Center. Transfer requests may be made by telephone (during the
       Accumulation Period), facsimile, or by written direction. Please note
       that no transfers may be made within thirty days before Maturity Date.


                                      13
<PAGE>
 
   (c) Transfer requests must clearly specify the amount to be transferred from
       each Division or Segment (if the Fixed Account is available) and the
       Division or Segment to which amounts are to be transferred. Unless
       otherwise specified, transfers from a Segment of the Fixed Account will
       be taken on a first-in, first-out basis. Transfer requests made during
       the Annuity pay-out period must specify the percentage to be transferred
       among the Divisions of the Separate Account.

   (d) Transfers to a Segment of the Fixed Account may not be less than $1,000.
       If the Segment elected is not available, the transfer will not be
       processed.

   (e) Transfers made from the Fixed Account are subject to a Market Value
       Adjustment ("MVA") unless the transfer is being taken from an Accumulated
       Amount within thirty days prior to its Expiration Date. The MVA will be
       applied as of the effective date of the transfer.

   (f) Transfer fees will be deducted from the Division or Segment from which
       the transfer has been made, unless the balance remaining in such Division
       or Segment is insufficient to cover the applicable transfer fee. If this
       is the case, the transfer fee will be deducted from the amount being
       transferred.

   (g) We reserve the right to limit the number and frequency of transfers made
       during a Contract Year.

   (h) After a payout option has been invoked, transfers may not be made between
       a Fixed Income and a Variable Monthly Income option.

TELEPHONE TRANSFERS

Contract Owners, subject to the limitations described below, may make transfers
among either Divisions or the Fixed Account (if available) during the
Accumulation Period by telephoning a transfer request to the Service Center at
its toll free telephone number. This feature will be made automatically
available to Contract Owners unless MML Bay State receives different
instructions. Through use of this toll free number, Contract Owners may also
obtain information concerning the Contract including Accumulated Values. This
service is not available to Contracts owned by Custodians or Trustees of
Qualified Plans, or Contracts held by Guardians. Normal transfer provisions
apply.

MML Bay State will not be liable for complying with any telephone instructions
it reasonably believes to be genuine, nor for any loss, damage, cost or expense
in acting on telephone instructions. MML Bay State will employ reasonable
procedures to ensure the legitimacy of telephone transfer requests. Such
procedures may include, among others, requiring forms of personal identification
prior to acting upon telephone instructions, providing written confirmation of
such transactions to the Contract, and/or tape recording of telephone transfer
request instructions received from a Contract Owner. If we fail to follow such
procedures, we may be liable for losses due to unauthorized or fraudulent
instructions.

AUTOMATIC TRANSFERS

MML Bay State offers You two automatic transfer options described below. They
are available any time before the Maturity Date. The automatic transfer options
are not available for use with the Fixed Account. Only one of the automatic
transfer options may be in effect at a time. Both options are subject to the
transfer rules discussed above. Although no charge is currently imposed for this
service, MML Bay State reserves the right to impose a fee in the future.

Dollar Cost Averaging

Dollar Cost Averaging is a feature whereby a Contract amount is periodically
transferred from one Division of the Separate Account to one or more other
designated Divisions of the Separate Account. Once the feature is elected, these
transfers occur automatically at the frequency elected monthly, quarterly,
semiannually, or annually.

Dollar Cost Averaging provides a mechanism designed to minimize the negative
effects of short-term market fluctuations. Over a period of time, an investor
may, at least theoretically, be able to purchase more units than he or she would
have been able to purchase had all monies been invested on a single Valuation
Date when the value of the units was high.

Dollar Cost Averaging may be available at any time, provided that the Division
from which the automatic transfers will be made has a value of at least $6,000.
The minimum amount any Division may receive is $100. All Divisions are available
for use with this feature.

Asset Reallocation

You may elect the Asset Reallocation option as a means of maintaining a constant
allocation of Accumulated Value among the Divisions in which You have allocated
Your monies. If You elect this option, we will make automatic transfers among
selected Divisions on a quarterly, semiannual, or annual basis as You instruct
us. A minimum Accumulated Value of $20,000 is required in order to elect this
option. Allocations will be made on a basis consistent with the allocation
selected for new purchase payments.

RIGHT TO RETURN CONTRACTS
    
You may return Your Contract to MML Bay State (at its Service Center) at any
time within 10 days after the Contract has been delivered to you (unless a
longer period is required by applicable state law). The Contract must be
accompanied by a written request signed by You that indicates You wish to return
the Contract. If You exercise this right and Your Contract is not an IRA, then
You will receive the Accumulated      


                                      14
<PAGE>
 
Value of the Contract plus any premium tax deductions, except where state law
requires us to return the amount of purchase payment(s) made less the net amount
of partial redemptions. If You exercise this right and Your Contract is an IRA,
You will not receive less than the amount of purchase payment(s) made less the
net amount of partial redemptions. For this purpose, the Accumulated Value of
the Contract will be determined as of the Valuation Time on the date on which
the Contract is received at MML Bay State's Service Center or at the next
Valuation Time after receipt if the Contract is received on other than a
Valuation Date.

THE DEATH BENEFIT

A death benefit is paid upon the death of either the Contract Owner (for jointly
owned Contracts, upon the first death of the two Owners) or Annuitant. If a
Contract Owner and Annuitant are the same, the Death Benefit paid will be the
Annuitant Death Benefit.

Contract Owner Death Benefit

If a Contract Owner, who is not the annuitant, dies prior to the Maturity Date,
the named beneficiary will receive the Cash Redemption Value of the Contract.

Annuitant Death Benefit

Historically, variable annuities have guaranteed a return of premiums less
withdrawals as a minimum standard death benefit. This Contract offers one of two
enhancements, depending on Your contract state.

If the Annuitant dies before the Maturity Date, the beneficiary named in the
Contract will receive the greater of: (a) the total of all purchase payments
made to the Contract less all partial redemptions accumulated at 5% to
Annuitant's 75th birthday and 0% thereafter, but not more than two times the
difference between all purchase payments and all redemptions; or (b) the
Accumulated Value of the Contract less any applicable Administrative Charge (and
any Sales Charge, if the Annuitant's age on the Contract Date exceeds 75).
    
In certain states, the death benefit described above may not be available for
Annuitant's whose issue age is less than 76. In those instances, the death
benefit during the first three Contract years will be equal to the greater of:
(a.) the total of all purchase payments made to the Contract less all partial
redemptions; or (b.) the Accumulated Value of the Contract less any applicable
Administrative Charge. During any subsequent three Contract Year period, the
death benefit will be the greater of: (a.) the death benefit on the last day of
the previous three Contract Year period plus any purchase payments made less all
partial redemptions since then; or (b.) the Accumulated Value of the Contract
less any applicable Administrative Charge.      

In any case, the amount of Death Benefit received will be reduced by the amount
of any applicable premium tax.

The Death Benefit is determined as of the Valuation Date which is on or next
follows the date on which due proof of death is received at the Service Center.
The death benefit will be paid within seven days of receipt of due proof of
death and all other requirements. With MML Bay State's consent, the death
benefit may be applied under one or more of the payment options provided for in
the Contract (see - Payment Options). If a Payment Option is not selected, the
death benefit will be paid in one sum.

A beneficiary who is the surviving spouse of the Contract Owner of a Contract
issued as an IRA may elect to treat the Contract as if he or she were the
Contract Owner.

REDEMPTION PRIVILEGES

Subject to the special rules regarding TSAs, discussed below, You may redeem all
or part of the Accumulated Value of a Contract on or prior to its Maturity Date
if the Annuitant is alive. The amount of any partial redemption, however, must
be at least $100, and requests for a partial redemption which would reduce the
Accumulated Value of the Contract to less than $1,000 plus outstanding premium
taxes will be treated as a request for a full redemption. You may incur a Sales
Charge upon redemption. (See - CHARGES AND DEDUCTIONS.) Any partial redemption
will be paid in one sum. If the entire Contract is redeemed, the cash redemption
value may be paid in one sum or applied under one or more of the payment
options. You must designate the Division(s) (or the Segment of the Fixed
Account, if available) from which any partial redemption is to be made. Unless
otherwise specified, partial redemptions from a Segment of the Fixed Account
will be taken on a first-in, first-out basis. A partial redemption from a
Division will reduce the number of Accumulation Units in that Division by an
amount equal to the sum of the redemption payment plus any Sales Charge, divided
by the Accumulation Unit Value.

The Accumulation Unit value on redemption is determined as of the Valuation Time
on the date on which the written request for redemption is received in good
order at the Service Center or, if that date is not a Valuation Date, on the
next Valuation Date after receipt.
    
Redemption payments from a Separate Account will be made within seven days (or a
shorter period if required by law) after written request in good order is
received at MML Bay State's Service Center. The right of redemption may be
suspended or payments postponed whenever: (1) the New York Stock Exchange is
closed, except for holidays and weekends; (2) the Securities and Exchange
Commission has determined that trading on the New York Stock Exchange is
restricted; (3) the Securities and Exchange Commission permits suspension or
postponement and so orders; or (4) an emergency exists, as defined by the
Securities and Exchange Commission, so that valuation of the assets of each
Separate Account or disposal of securities held by it is not reasonably
practicable.      

In addition, a purchase payment amount is not available to satisfy a redemption
request until the check, or other instrument by which the purchase payment was
made, has been honored.

Redemptions of amounts from the Fixed Account may be de-


                                      15
<PAGE>
 
layed for up to six months from the date the request is received by us at our
Service Center. If payment is delayed 30 days or more, we will add interest at
an annual rate of not less than 3%.

Amounts withdrawn may be includable in the gross income of the Contract Owner in
the year in which the withdrawal occurs. Additionally, a 10% tax penalty may be
applicable (as described more fully in the Penalty Taxes section).

Redemption payments may be subject to federal income tax and elective and/or
mandatory tax withholding. (See FEDERAL TAX STATUS).

AUTOMATIC PARTIAL REDEMPTIONS

An Automatic Partial Redemption program permitting Contract Owners to elect to
receive automatic partial redemptions on a periodic basis is available on a
limited basis. All applicable limitations concerning redemptions apply to this
program. Additionally, automatic partial redemptions may be subject to penalty
taxes.

This program is available only during the Accumulation Period of the Contract.

Although no charge is imposed for processing automatic partial redemptions
currently, MML Bay State reserves the right to impose a fee for this program in
the future.

TAX SHELTERED ANNUITY
REDEMPTION RESTRICTIONS

The redemption of Internal Revenue Code Section 403(b) annuities (Tax Sheltered
Annuities, "TSAs") may be restricted. Specifically, salary reduction
contributions after 1988 and post-1988 earnings on all salary reduction
contributions may not be distributed to the Annuitant until age 59 1/2, death,
disability, or separation from service with the TSA employer. Such salary
reduction contributions may be withdrawn, however, for "hardship".

The Annuity (Pay-Out) Period

ANNUITY BENEFITS
    
You may elect to change the Maturity Date of Your Contract. The Maturity Date
may not be later than the Contract anniversary nearest the Annuitant's 90th
birthday (or at an earlier date if required by applicable state law). In
general, in order to avoid adverse tax consequences, distributions, either by a
partial redemption or by maturing the Contract, from a Contract issued as an IRA
or as a TSA or under a qualified plan should begin for the calendar year in
which the Annuitant reaches age 70 1/2 and should be made each year thereafter
in an amount no less than the Accumulated Value of the Contract at the end of
the previous year divided by the applicable life expectancy (see Taxation of
Qualified Plans, TSAs, and IRAs and Roth IRAs, for additional information). You
may elect to defer the Maturity Date to any permissible date after the
previously specified Maturity Date, provided that a written notice within 90
days before the Maturity Date then in effect is received by MML Bay State at the
Service Center. You also may elect to advance the Maturity Date to a date prior
to the specified Maturity Date or prior to any new Maturity Date You may have
selected, provided that written notice is received at MML Bay State's Service
Center at least 30 days before the Maturity Date elected. For additional rules
regarding TSAs. (See -Tax Sheltered Annuity Redemption Restrictions.)      

When Your Contract approaches its Maturity Date You may choose to receive either
Fixed Income payments, (referred to as the "Fixed Income Option" in Your
Contract), Variable Monthly Income payments (referred to as the "Variable Income
Option" in Your Contract), or a combination of the two. You also may elect to
receive the Maturity Value in one sum. If You have made no election within
thirty days prior to the Maturity Date, the Contract will automatically pay a
Variable Monthly Income under a life income option with payments guaranteed for
10 years.

PAYMENT OPTIONS

You may elect either a Fixed or a Variable Monthly Income payment option by
submitting a written request in a form satisfactory to MML Bay State. MML Bay
State must receive this request at the Service Center 30 days prior to the
Maturity Date of the Contract. For a description of payment options from which
You (or in some cases a Beneficiary) may choose, You should refer to the
Contracts. Generally, once selected, You may not change Your payment option.

Income payments may be received under several different payment options. If the
value of a Contract applied to any payment option is less than $2,000 or
produces an initial Income payment of less than $20, MML Bay State may discharge
its obligation by paying the value applied, less any applicable Sales Charge, in
one sum to the person entitled to receive the first annuity payment.

Upon Your request, MML Bay State will endorse a Contract to eliminate or
restrict any payment option in order that the plan pursuant to which the
Contract is issued remains qualified under the Internal Revenue Code, provided
such endorsement is not otherwise contrary to law. MML Bay State may make
available payment options in addition to those set forth in the Contract.

You may transfer amounts among the Divisions if the Variable Monthly Income
option is selected subject to transfer restrictions described in General
Transfer Rules.

Fixed Income Option
    
If You select a Fixed Income, each payment will be for a fixed dollar amount and
will not vary with or reflect the investment performance of the Separate
Account. For further information regarding the Fixed Income and the payment 
     

                                      16
<PAGE>
 
options thereunder, You should refer to Your Contract.

Variable Monthly Income Option

If You select a Variable Monthly Income, amounts held in the Fixed Account that
are to be used to provide Variable Monthly Income payments will be credited to
the MML Money Market Division of the Separate Account unless the Contract Owner
instructs MML Bay State otherwise. Each annuity payment will be based upon the
value of the Annuity Units credited to Your Contract.

You may transfer among the Divisions no more frequently than once every 3 months
under this option. (See - General Transfer Rules for transfer guidelines.)

The number of Annuity Units in each Division to be credited to Your Contract is
based on the value of the Accumulation Units in that Division and the applicable
Purchase Rate. The Purchase Rate will differ according to the payment option You
have elected and takes into account the age, year of birth and sex of the
Annuitant. The value of the Annuity Units will vary with, and reflect the
investment performance of, each Division to which Annuity Units are credited
based on an Assumed Investment Rate of 4% per year. This Rate is a fulcrum rate
around which Variable Monthly Income payments will vary. An actual net rate of
return for a Division for the month greater than the Assumed Investment Rate
will increase Variable Monthly Income payments attributable to that Division. An
actual net rate of return for a Division for the month less than the Assumed
Investment Rate will decrease Variable Monthly Income payments attributable to
that Division.

For a more detailed description of how the value of an Annuity Unit and the
amount of Variable Monthly Income payments are calculated, see the Statement of
Additional Information.

Fixed-Time Payment Option

If You elect this option, Variable Monthly Income payments will be made for any
period selected, up to 30 years. If provided in the payment option election, You
may withdraw the full amount, subject to any applicable Sales Charge of the then
present value of the remaining unpaid Variable Monthly Income payments. (See -
CHARGES AND DEDUCTIONS.) The present value will be calculated using an assumed
investment rate of 4% per year unless a lower rate is required by state law. A
mortality risk charge continues to be assessed against Contract values under
this option. (See - CHARGES AND DEDUCTIONS.)

Life Income Payments

If You elect this option, Variable Monthly Income payments will be made during
the lifetime of the Annuitant, either: (1) without any guaranteed number of
payments; or (2) with a guaranteed number of payments for 5 or 10 years. Of
these two alternatives, alternative (1) offers the maximum level of monthly
payments since there is no guarantee of a higher number of payments and no
provision for payments to the beneficiary upon the death of the Annuitant. Since
there is no such guarantee, however, it would be possible to receive only one
annuity payment if the Annuitant died prior to the due date of the second
annuity payment, two if he or she died before the third annuity payment date,
etc.

Joint-and-Survivor Life Income Payments

If You elect this option, Variable Monthly Income payments will be made during
the joint lifetime of the two Annuitants and thereafter during the lifetime of
the survivor, either: (1) without a guaranteed number of payments; or (2) with a
guaranteed number of payments for 10 years from the date the payments begin.

Joint-and-Survivor Life Income Payments
(Two-Thirds to the Survivor)

If You elect this option, Variable Monthly Income payments will be made during
the joint lifetime of the two annuitants, and thereafter at two-thirds the prior
rate during the lifetime of the survivor, in both cases without a guaranteed
number of payments.

Payments After Death of Annuitant

Generally, if a payment option with a guaranteed number of payments is elected,
and the Annuitant(s) should die before the guaranteed number of payments have
been completed, MML Bay State will continue making the guaranteed payments to
the designated beneficiary.

Special Limitations

Where the Contract is issued pursuant to a TSA, or as an IRA, there are special
limitations on the types of payment options which You may elect.

Charges and Deductions

1.  ASSET CHARGE

    MML Bay State receives a daily-computed charge against the assets of the
    Separate Account (the "Asset Charge") for: (1) assuming the risks that (a)
    its estimates of longevity will turn out to be inadequate, and (b) the
    Administrative Charge may be insufficient to cover the administrative
    expenses associated with the Contract; (2) other administrative expenses;
    and (3) the Death Benefit. The Asset Charge is currently equal to 1.40% on
    an annual basis of the net asset value of the Separate Account assets
    attributable to the Contracts.

    The mortality and expense risk part of this charge will be computed daily at
    an annual rate, currently equal to 1.15% of the net asset value of the
    Separate Account assets attributable to the Contracts (0.30% is for assuming
    mortality risks and 0.85% is for assuming expense risks). MML Bay State
    reserves the right to raise this rate up to 1.25%.

    The administrative expense part of this Charge will be computed daily at an
    annual rate of 0.15%.


                                      17
<PAGE>
 
    The third component of the Asset Charge is 0.10% assessed to reimburse MML
    Bay State for the cost of providing the enhanced Death Benefit under the
    Contract. For more information concerning the enhanced Death Benefit. (See -
    Annuitant Death Benefit.)

2.  ADMINISTRATIVE CHARGE

    In addition to that portion of the Asset Charge assigned to administrative
    expenses, each year on the Contract anniversary date a charge is imposed
    against each Contract to reimburse MML Bay State for administrative expenses
    incurred by MML Bay State during the previous year relating to the issuance
    and maintenance of the Contract (the "Administrative Charge"). The
    Administrative Charge is also imposed on death, maturity, or full
    redemption. The Administrative Charge is currently $30 per year. MML Bay
    State reserves the right to increase the Administrative Charge up to $50 per
    year. This charge is not designed to produce a profit and is subject to
    statutory limitations.

    If a Contract's Accumulated Value is $50,000 or more when the Administrative
    Charge would be deducted, the Administrative Charge will be waived. This
    charge will be deducted on a pro rata basis from each Division of the
    Separate Account and then pro-rata from Segments of the Fixed Account.
    Deductions from Segments will be made on a first-in, first-out basis.

3.  CONTINGENT DEFERRED SALES CHARGE

    Sales charges are not deducted at the time a purchase payment is made.
    Instead, to reimburse MML Bay State for sales expenses including
    commissions, sales literature and related costs, a Contingent Deferred Sales
    Charge (the "Sales Charge") may be imposed upon a full or partial
    redemption, upon maturity, and upon certain death benefits.

    Sales charges are based on the purchase payments made and the time that has
    passed since we received them. The part of the sales charge related to each
    purchase payment is a level percentage of that payment during each year
    since it was paid. For each successive year, the percentage decreases until
    it becomes zero. Sales charge percentages for each purchase payment are
    shown in the table below.

                           Sales Charge Percentages

- --------------------------------------------------------------------------------
   Full Years since payment    0    1    2    3    4    5    6    7 or more
- --------------------------------------------------------------------------------
   Percentage                 7%   6%   5%   4%   3%   2%   1%         0%
- --------------------------------------------------------------------------------

Example:  You make a $1,000 purchase payment on May 10, 1991. The sales charge
                            related to this purchase payment is: 
                            $70 from May 10, 1991, through May 9, 1992; 
                            $60 from May 10, 1992, through May 9, 1993;
                            
                            $10 from May 10, 1997, through May 9, 1998; and $0
                            thereafter.

Subject to the limits stated below, the Sales Charge at any time is based solely
on the purchase payments assumed to be redeemed at that time. In determining the
Sales Charge, we assume that purchase payments are redeemed in the order in
which they are paid. Any amounts in excess of purchase payments are assumed to
be redeemed last.
    
Each Contract Year, You may redeem the following amounts without incurring a
Sales Charge:      
    
(1)  all unredeemed purchase payments that are at least seven years old; and 
     

(2) 10% of the purchase payments that are less than seven years old.
    
No Sales Charge will be imposed upon a death benefit payable upon the
Annuitant's death if the Contract was issued to an Annuitant less than 76 years
old. Also a Sales Charge will not be assessed upon a full redemption or
maturity of the Contract if all proceeds of the Contract are:      
    
(1) applied under a variable lifetime payment option or variable fixed-time
    payment option (with payment for 10 years or more) in the Contract; or      

(2) applied under a fixed or combination fixed-variable lifetime payment option
    or fixed-time payment option (with payments for 10 years or more) in the
    Contract and the Annuitant is age 59 1/2 or older.
    
The Sales Charge may also be eliminated when an agent of MML Bay State sells a
Contract to specified members of his or her family.      

To the extent sales expenses are not covered by the sales charge, they will be
recovered from MML Bay State's surplus, which may include proceeds derived from
the asset charge described above.

Any available waiver of a Sales Charge will be applied on a non-discriminatory
basis.


                                      18
<PAGE>
 
4.  PREMIUM TAXES

    Several states (and certain municipalities) levy premium taxes on annuities.
    Currently, no premium tax will be deducted when purchase payments are
    received; any applicable premium tax will be deducted at the time of
    redemption, death, maturity or annuitization. MML Bay State reserves the
    right to deduct premium taxes at the time when a purchase payment is made.
    Premium tax rates on annuities currently range up to 3.5%.
    
5.  FUND EXPENSES      

    The Accumulated Value of the Separate Account reflects the value of shares
    held in the Oppenheimer Trust and the MML Trust. Each Trust charges certain
    investment advisery fees and other expenses against the value of each Fund.
    For a complete description of the expenses and deductions for each Trust,
    please review the accompanying prospectuses for each Trust.

The Fixed Account and the
Market Value Adjustment
Feature

The following summarizes certain features of the Fixed Account which is
available as part of the Contract in the majority of states during the
Accumulation Period. Please review the Prospectus for the Fixed Account before
making any allocations to it. The Fixed Account offers different Segments which
provide the option of earning interest at one or more Guaranteed Rates on all or
a portion of Your Accumulated Value. As of the date of this prospectus, we offer
Segments with Guarantee Periods of 1, 3, 5, and 7 years.

You may allocate purchase payments or transfer all or a portion of Your
Accumulated Value to one or more Segments of the Fixed Account. Amounts credited
to a Segment of the Fixed Account will earn interest at the Guaranteed Rate
applicable on the date the amounts are credited. The applicable Guarantee Rate
does not change during the Guarantee Period. You may have multiple amounts
credited to a single Segment or multiple Segments. We may change the Segments
available for allocations of purchase payments, transfers and renewals at any
time. The Guaranteed Rate for any Segment may never be less than 3%. Please note
that if You allocate sums to the Fixed Account, You will bear the investment
risk that such amounts will increase or decrease in value.

The end of a Guarantee Period for a specific amount credited to a Segment is
called its Expiration Date. At that time, the Guarantee Period normally "renews"
and we begin crediting interest for a new Guarantee Period lasting the same
amount of time as the one just ended. The Accumulated Amount then earns interest
at the new Guaranteed Rate applicable at the time of renewal. You may also
choose different Segments from among those we are then offering, or

You may transfer all or a portion of the Accumulated Amount to the Separate
Account.

To the extent permitted by law, we reserve the right at any time to offer
Segments with Guarantee Periods that differ from those available when Your
Contract was issued. We also reserve the right, at any time, to stop accepting
new amounts credited, transferred, or renewed for a particular Segment.
    
Between 75 and 45 days before the end of the Expiration Date for an Accumulation
Amount, we will inform You of the Guaranteed Rates being offered and Segments
available as of the date of such notice. The Guaranteed Rates on the date of a
renewal may be more or less than the rates quoted in such notice.      

If Your Accumulated Amount's Segment is no longer available for new amounts
credited, or You choose a different Segment that is no longer available, we will
try to reach You so that You may make another choice.
    
If a choice is not made at this point, the Segment with the next shortest
Guarantee Period available will be used and if not available, the Segment with
the next longest Period will be used.      

MARKET VALUE ADJUSTMENT

Any withdrawal of Your Accumulated Amount will be subject to a Market Value
Adjustment ("MVA") unless the effective date of the withdrawal is within 30 days
prior to the end of a Guarantee Period. For this purpose, redemptions,
transfers, death benefits based on a Contract Owner's death, and maturity
amounts are treated as withdrawals. The MVA is an adjustment that will be
applied to the amount being withdrawn which is subject to the MVA, after the
deduction of any applicable Administrative Charge and before the deduction of
any applicable Sales Charge. The MVA can be positive or negative. The amount
being withdrawn after application of the MVA can therefore be greater than or
less than the amount withdrawn before application of the MVA.

The MVA will reflect the relationship between the Current Rate (as defined
below) for the Accumulated Amount being withdrawn and the Guaranteed Rate. It
also reflects the time remaining in the applicable Guarantee Period. Generally,
if the Guaranteed Rate is lower than the applicable Current Rate, then the
application of the MVA will result in a lower payment upon withdrawal.
Similarly, if the Guaranteed Rate is higher than the applicable Current Rate,
the application of the MVA will result in a higher payment upon withdrawal.

The Market Value Adjustment which is applied to the amount being withdrawn is
determined by using the following formula:

                                                        
                  (                    )                 
 (MVA  =  Amount x( (1 +i ) /n/  -  1) )
                  ( ( ----) ---        )
                  ( ( 1+j ) 365        )
where,


                                      19
<PAGE>
 
Amount is the amount being withdrawn from a given accumulated amount less any
applicable administrative charges.

i, is the Guaranteed Rate being credited to the Accumulated
Amount subject to the MVA.

j, the "Current Rate," is the Guaranteed Rate, available as of the effective
date of the application of the MVA, for current allocations to the Segment with
a Guarantee Period equal to the time remaining to the Expiration Date for the
amount being withdrawn rounded to the next higher number of complete years.

n, is the number of days remaining in the Guarantee Period
of the amount subject to the MVA.

In the determination of "j," if MML Bay State currently does not offer the
applicable Segment, we will determine "j" above using a method as described in
the Statement of Additional Information.

Distribution
    
MML Distributors, LLC ("MML Distributors"), 1414 Main Street, Springfield, MA
01144-1013, is the principal underwriter of the Contracts pursuant to an
Underwriting and Servicing Agreement to which MML Distributors, MML Bay State
and the Separate Account are parties. MML Investors Services, Inc. ("MMLISI"),
also located at 1414 Main Street, Springfield, MA 01144-1013, serves as the
co-underwriter of the Contracts. Both MML Distributors and MMLISI are registered
with the Securities and Exchange Commission (the "SEC") as broker-dealers under
the Securities Exchange Act of 1934 and are members of the National Association
of Securities Dealers, Inc. (the "NASD"). The maximum commission a broker-dealer
will receive is 6.25%.      

MML Distributors may enter into selling agreements with other broker-dealers
which are registered with the SEC and are members of the NASD ("selling
brokers"). Contracts are sold through agents who are licensed by state insurance
officials to sell the Contracts. These agents are also registered
representatives of selling brokers or of MMLISI.

Additionally, Oppenheimer Funds Distributor, Inc. ("OFDI"), a subsidiary of OFI,
and MML Distributors have entered into an agreement pursuant to which OFDI has
agreed to promote sales of the product through wholesale distribution
arrangements with such broker-dealers. Registered representatives of the
particular broker-dealer, who are also properly licensed to sell MassMutual
products, may make such sales.

MML Distributors does business under different variations of its name; including
the name MML Distributors, L.L.C. in the states of Illinois, Michigan, Oklahoma,
South Dakota and Washington; and the name MML Distributors, Limited Liability
Company in the states of Maine, Ohio and West Virginia.

From time to time, OFDI may enter into special arrangements with broker-dealers
which may provide for the payment of higher compensation to such broker-dealers
in connection with the sale of Contracts. Prospective purchasers of the
Contracts will be informed of such arrangements prior to the completion of the
sale of the Contracts.

Miscellaneous Provisions

TERMINATION OF LIABILITY

MML Bay State's liability under a Contract terminates on the death of the
Contract Owner or Annuitant(s) and on the completion of any guaranteed payments.
There is no liability for any proportionate monthly annuity payment from the
date of the last payment to the date of death.
    
ADJUSTMENT OF UNITS AND
UNIT VALUES      
    
MML Bay State reserves the right in its sole discretion to split or consolidate
the number of Accumulation Units or Annuity Units for any Division of the
Separate Account and correspondingly decrease or increase the Accumulation or
Annuity Unit values for any such Division whenever it deems such action to be
desirable. Any such adjustment will have no adverse effect on rights under the
Contracts.      
    
PERIODIC STATEMENTS      

While the Contract is in force prior to the Maturity Date and before the death
of the Annuitant, MML Bay State will furnish to the Contract Owner at least
semiannually a status report showing the number of Accumulation Units credited
to each Division of the Separate Account, the corresponding Accumulation Unit
values, the value of amounts in the Fixed Account (if available) and the
Accumulated Value of the Contract.

CONTRACT OWNER'S VOTING RIGHTS

As long as the Separate Account continues to operate as a unit investment trust
under the Investment Company Act of 1940, the Contract Owner during the lifetime
of the Annuitant, or the beneficiary after the Annuitant's death, will be
entitled to give instructions as to how the shares of the Funds held in the
Separate Account (or other securities held in lieu of such shares) deemed
attributable to the Contract should be voted at meetings of shareholders of the
Funds or the Trusts. Those persons entitled to give voting instructions will be
determined as of the record date for the meeting.
    
The number of Fund shares held in the Separate Account deemed attributable to a
Contract prior to its Maturity Date and during the lifetime of the Annuitant
will be determined by dividing the Contract's value held in each Division of the
Separate Account, if any by $100. Fractional votes are counted. After the
Maturity Date or after the death of the Annuitant, the number of Fund shares
deemed attributable to the Contract will      


                                      20
<PAGE>
 
be based on the liability for future Variable Monthly Annuity payments under the
Contract as of the record date and thus the voting rights will decrease as
payments are made.

Contract Owners or beneficiaries will receive proxy material and a form with
which voting instructions may be given. Fund shares held by the Separate Account
as to which no effective instructions have been received or which are
attributable to assets transferred from MML Bay State's general account will be
voted for or against any proposition in the same proportion as the shares as to
which instructions have been received.

In situations where the Annuitant is not the Contract Owner, the Annuitant will
have the right to instruct the Contract Owner with respect to the votes
attributable to any vested interest the Contract Owner has in the Contract. MML
Bay State's obligation in this instance will be to make available to the
Contract Owner copies of the proxy material for distribution to the Annuitant.
Votes representing interests as to which the Contract Owner is not instructed
may, in turn, be voted by the Contract Owner in his discretion.

RESERVATION OF RIGHTS

MML Bay State may, at any time, make any change in a Contract to the extent that
such change is required in order to make the Contract conform with any law or
regulation issued by any governmental agency to which MML Bay State is subject.
If shares of any Fund should not be available, or, if in the judgment of MML Bay
State, investment in shares of a Fund is no longer appropriate in view of the
purposes of a Division of the Separate Account, shares of other series of the
Trusts or of other registered, open-end investment companies may be substituted
for such Fund shares. Payments received after a date specified by MML Bay State
may be applied to the purchase of shares of another Trust series or investment
company in lieu of shares of that Fund. Additionally, if in the judgment of MML
Bay State, investment in shares of a Fund is no longer appropriate, MML Bay
State reserves the right to withdraw availability of a Division of the Separate
Account for further amounts being credited. In any event, approval of the SEC
must be obtained. MML Bay State reserves the right to change the name of a
Separate Account or to add Divisions to the Separate Account for the purpose of
investing in additional investment vehicles. Additionally, we reserve the right
to terminate the Contract: (a) if no purchase payment has been received for at
least two consecutive years measured from the date we received the last purchase
payment; and (b) if the Accumulated Value less any deduction we would make for
premium taxes, the Cash Redemption Value and the unredeemed premium payments are
all less than $2,000. Before exercising this right, we will provide You with
written notice of our decision.

Federal Tax Status

INTRODUCTION

The ultimate effect of federal income taxes on the value of the Contract, on
annuity payments, and on the economic benefit to the Contract Owner, Annuitant
or beneficiary depends on a variety of factors including the type of retirement
plan for which the Contract is purchased and the tax and employment status of
the individual concerned. The discussion contained herein is general in nature
and is not intended as tax advice. Each person concerned should consult a
competent tax adviser for complete information and advice. No attempt is made to
consider any applicable state or other local tax laws. Moreover, the discussion
herein is based upon MML Bay State's understanding of current federal income tax
laws as they are currently interpreted. No representation is made regarding the
likelihood of continuation of those current federal income tax laws or of the
current interpretations by the Internal Revenue Service ("IRS").

TAX STATUS OF MML BAY STATE

Under existing federal law, no taxes are payable by MML Bay State on investment
income and realized capital gains of the Separate Account credited to the
Contracts. Accordingly, MML Bay State does not intend to make any charge to the
Separate Accounts to provide for company income taxes. MML Bay State may,
however, make such a charge in the future if an unanticipated construction of
current law or a change in law results in a company tax liability attributable
to the Separate Account.

MML Bay State may incur state and local taxes (in addition to premium taxes) in
several states. At present, these taxes are not significant. If they increase,
however, charges for such taxes attributable to the Separate Account may be
made.

Taxation of Contracts in General

Under Section 817(h) of the Internal Revenue Code (the "Code") a Contract (other
than one used in a tax-qualified retirement plan) will not be treated as an
annuity contract and will be taxed on the annual increase in earnings if, as of
the end of any quarter, the Funds, or the Fund on which the Contract is based
are not adequately diversified in accordance with regulations prescribed by the
Treasury Department. It is anticipated that the Trusts will comply with the
Code's diversification requirements.

Subject to certain annuity distribution rules (see - Annuity Distribution Rules
of Section 72(s)), annuity payments under the Contracts are taxable under
Section 72 of the Code. For contributions made after February 28, 1986, a
Contract Owner that is not a natural person will be taxed on the annual increase
in the earnings of a Contract unless the Contract Owner holds the Contract as
agent for a natural person. Otherwise, increases in the value of a Contract are


                                      21
<PAGE>
 
not subject to tax until actually or constructively received.
    
Amounts received prior to the Maturity Date from Contracts not under tax
qualified arrangements (see - Taxation of Qualified Plans TSAs, IRAs and Roth
IRAs, for a discussion of Contracts used in the qualified plan market) are
subject to tax to the extent of any earnings or gains in the Contract; amounts
received which are in excess of such earnings or gains are considered a return
 of capital. Similarly, amounts borrowed upon the Contract will be treated as
amounts received under the Contract and will be taxable to the same extent. If
an individual Contract Owner transfers ownership, for other than full and
adequate consideration, the Contract Owner will be taxed on the transfer as
though he or she had taken a full redemption of the Contract. For Contracts
entered into after October 21, 1988, all annuity contracts issued by the same
insurer and its affiliates to the same Contract Owner within the same calendar
year must be aggregated in determining the amount of gain realized on a
withdrawal from any one.       

If the Contract is obtained in a tax-free exchange of contracts under Section
1035 of the Code, different tax rules may apply. If a distribution prior to the
Maturity Date of a contract obtained in such an exchange is entirely
attributable to investments in the surrendered contract prior to August 14,
1982, the distribution will first be considered a return of capital to the
extent of those investments and only the amounts received in excess of those
investments will be regarded as taxable earnings or gains.

PENALTY TAXES
    
In addition to the foregoing tax consequences, certain distributions under the
Contract will be subject to a penalty tax under Code Section 72(q) (for non-tax
qualified Contracts) or 72(t) (for Contracts in tax qualified plans see -
Taxation of Qualified Plans, TSAs, IRAs and Roth IRAs) of 10% of the amount of
the distribution that is includable in gross income. However, the following
distributions from non-tax qualified Contracts currently are not subject to the
penalty tax: (1) withdrawals made after the Contract Owner is 59 1/2 years old;
(2) payments made to a beneficiary (or to the estate of the Contract Owner) on
or after the death of the Contract Owner; (3) payments attributable to a
Contract Owner becoming disabled; or (4) substantially equal periodic payments
made (at least annually) for the lifetime (or life expectancy) of the Contract
Owner or for the joint lifetimes (or joint life expectancies) of the Contract
Owner and the beneficiary.      

When monthly annuity payments commence, they are taxable as ordinary income in
the year of receipt to the extent that they exceed that portion of the
"Investment in the Contract" allocable to that year. The Investment in the
Contract will equal the gross amount of purchase payments made under the
Contract less any amount that was previously received under the Contract but was
not included in gross income. The Investment in the Contract would also be
increased by any amount that was previously included in gross income under the
Contract but was not received. This amount, divided by the anticipated number of
monthly annuity payments, gives the "excludable amount," which is the portion of
each annuity payment considered to be a return of capital and, therefore, not
taxable. Under this exclusion ratio, the total amount excluded from payments
actually received is limited to the Investment in the Contract. The rules for
determining the excludable amount are contained in Section 72 of the Code and
regulations thereunder and require adjustment when the payment option elected
provides a feature such as a guaranteed number of payments.

ANNUITY DISTRIBUTION RULES OF SECTION 72(S)
    
Annuity distribution requirements are imposed under Section 72(s) of the Code.
MML Bay State understands that these requirements do not apply to Contracts
issued to or under Qualified Plans, TSAs, IRAs and Roth IRAs.        
    
Under Section 72(s), a Contract will not be treated as an annuity subject to
Section 72 of the Code, unless it provides for certain required distributions
from and after the date of death of the Contract Owner. The Contracts will be
endorsed before issue to provide that annuity payments be made only in
accordance with these distribution requirements, as applicable.      
    
SPOUSAL CONTINUANCE       
    
Where the Annuitant and Owner are the same person and his/her spouse is named
the designated beneficiary of the contract then on the death of the
Annuitant/Owner the designated beneficiary may continue the contract in his/her
own name as Annuitant and Owner. The new Annuitant/Owner has all rights under
the contract including naming a new beneficiary and making additional purchase
payments.        

TAX WITHHOLDING
    
Certain tax withholding is imposed on payments that are made under the Contracts
(for Contracts in tax qualified plans, see Taxation of Qualified Plans, TSAs,
IRAs and Roth IRAs). Withheld amounts do not constitute an additional tax, but
are fully creditable on the individual tax return of each payee who is affected
by tax withholding. Furthermore, no payments will be subject to the withholding
if (1) it is reasonable to believe that the payments are not includable in gross
income, or (2) the payee elects not to have withholding apply. The payee may
make such an election either by filing an election form with MML Bay State or,
in the case of redemptions, by following procedures that MML Bay State has
established to afford payees an opportunity to elect out of withholding. These
forms and procedures will be provided to payees by MML Bay State upon a request
for payment.        

Unless the Payee elects not to have withholding apply (for Contracts in tax
qualified plans see - Taxation of Qualified Plans, TSAs and IRAs), MML Bay State
is required to with-


                                      22
<PAGE>
 
hold, for federal income tax purposes, 10% of the taxable portion of any
redemption payment or non-periodic distribution under the Contracts. Periodic
annuity payments under the Contracts are subject to withholding at the payee's
wage base rate. If the payee of these annuity payments does not file an
appropriate withholding certificate (obtainable from any local IRS office) with
MML Bay State, it will be presumed that the payee is married claiming three
exemptions.

TAX REPORTING

MML Bay State is required to report all taxable payments and distributions to
the IRS and to the payees. Payees will receive reports of taxable payments and
distributions by January 31 of the year following the year of payment.
    
TAXATION OF QUALIFIED PLANS, TSAS, IRAS AND ROTH IRAS        

The tax rules applicable to participants in retirement plans that qualify for
special federal income tax treatment ("Qualified Plans") vary according to the
type of plan and its terms and conditions.

Increases in the value of a Contract are not subject to tax until received by
the employee or his beneficiary. Monthly annuity payments under Qualified Plans
are taxed as described above (see - TAXATION OF CONTRACTS IN GENERAL, except
that the "investment in the Contract" under a Qualified Plan is normally the
gross amount of purchase payment made by the employee under the Contract or made
by the employer on the employee's behalf and included in the employee's taxable
income when made.

If the Annuitant receives a distribution that qualifies as a "lump sum
distribution" under the Code, he or she may be eligible for special "5-year
averaging" treatment of the funds received (or "10-year averaging" treatment if
he or she was age 50 or older on January 1, 1986). TSAs and IRAs are not
eligible for the special treatment under the "lump sum distribution" rules.
Effective for calendar years beginning January 1, 2000, five year averaging of
lump-sum distributions will no longer be available.
    
Certain TSA contributions may not be distributed to the Annuitant until age 59
1/2, death, disability, separation of service or hardship. (See - Redemption
Privileges.) Distributions from Qualified Plans, IRAs, Roth IRAs and TSAs may be
subject to a 10% penalty tax on amounts withdrawn before age 59 1/2. However,
the following distributions from Qualified Plans (and TSAs and IRAs except as
otherwise noted) are not subject to the penalty: (1) payments made to a
beneficiary (or the estate of an Annuitant) on or after the death of the
Annuitant; (2) payments attributable to an Annuitant becoming disabled; (3)
substantially equal periodic payments made (at least annually) for the lifetime
(or life expectancy) of the Annuitant or for the joint lifetimes (or joint life
expectancies) of the Annuitant and the beneficiary (for Qualified Plans and
TSAs, payments can only begin after the employee separates from service); (4)
payment for certain medical expenses; (5) payment after age 55 and separation
from service (not applicable to IRAs); (6) payments to an alternate payee
pursuant to a qualified domestic relations order under Code Section 414(p) (not
applicable to IRAs); (7) effective for calendar years beginning January 1, 1997,
withdrawals from IRAs by certain unemployed persons for payment of health
insurance premiums; (8) effective for calendar years beginning January 1, 1998,
withdrawals from IRAs for the payment of certain qualified higher education
expenses; and (9) effective for calendar years beginning January 1, 1998,
withdrawals from IRAs for certain first-time homebuyer expenses, subject to a
$10,000 lifetime cap. Qualified distributions from Roth IRAs are not subject to
the penalty tax. The exceptions applicable to IRAs also apply to Roth IRAs. 
     
    
IRAs are subject to limitations on the amount that may be contributed. The
deductibility of contributions by individuals or their spouses who are active
participants in an employer maintained pension or profit sharing plan may be
reduced based on the individual's adjusted gross income. In addition, certain
distributions from Qualified Plans and TSAs may be placed into an IRA on a
tax-deferred basis.       
    
In general, tax law requires that minimum distributions be made from Qualified
Plans by 5% owners, and IRAs begin(ning at age 70 1/2) (and from all others in
Qualified Plans and) TSAs at the later of age 70 1/2 or when the employee
retires. To avoid penalty taxes of 50 percent or more, required distributions,
including distributions which should have been distributed in prior years,
should not be rolled over to IRAs. No minimum distributions are required from a
Roth IRA.       

Distributions from Qualified Plans and TSAs are subject to mandatory federal
income tax withholding. MML Bay State is required to withhold 20% when a payment
from a Qualified Plan or TSA is an "eligible rollover distribution" and such
payment is not directly rolled over to another Qualified Plan, TSA or IRA. In
general, an "eligible rollover distribution" is any taxable distribution other
than: (1) payments for the life (or life expectancy) of the Annuitant, or for
joint life (or joint life expectancies) of the Annuitant and the beneficiary;
(2) payments made over a period of ten years or more; and (3) required minimum
distributions (see above). Plan administrators should be able to tell Annuitants
what other payments are not "eligible rollover distributions".

Taxable distributions that are not "eligible rollover distributions" are subject
to the withholding rules for annuities (See Tax Withholding.)
    
Special rules apply in the case of Roth IRAs. Roth IRAs are specially designated
IRAs. Contributions to Roth IRAs are not deductible and are limited based on
modified adjusted gross income. Contrary to regular IRAs, contributions are
permitted after age 70 1/2.       
    
Qualified distributions from Roth IRAs are not included in income. Distributions
that are not qualified distributions are treated first as a return of investment
to the extent of the       


                                      23
<PAGE>
 
    
individual's contributions to Roth IRAs and as a taxable distribution to the
extent of any excess. Roth IRAs are not subject to required minimum distribution
rules.       
    
An individual (other than a married individual filing separately) with an
adjusted gross income of $100,000 or less may roll over distributions within 60
days from a regular IRA to a Roth IRA of may convert a regular IRA into a Roth
IRA. While the rollover would be subject to tax, it would not be subject to the
10% premature distribution penalty tax. If the rollover occurs during 1998, the
income is spread out over four tax years.        

Performance Measures

MML Bay State may show the performance under the Contracts in the following
ways:

STANDARDIZED AVERAGE ANNUAL TOTAL RETURN

Except for Divisions of the Separate Account which have been in existence for
less than one year, MML Bay State will show the Standardized Average Annual
Total Return for a Division of the Separate Account which, as prescribed by the
rules of the SEC, is the effective annual compounded rate of return that would
have produced the cash redemption value over the stated period had the
performance remained constant throughout. The Standardized Average Annual Total
Return assumes a single $1000 payment made at the beginning of the period and
full redemption at the end of the period. It reflects a deduction for the Sales
Charge, the annual administrative charge and all other Fund, Separate Account,
and Contract level charges except premium taxes, if any. The annual
Administrative Charge will be apportioned among the Divisions of the Separate
Account based upon the percentages of Contracts investing in each of the
Divisions.

For Divisions of the Separate Account which have been in existence for less than
one year, MassMutual will show the aggregate total return as permitted by the
SEC. The aggregate total return assumes a single one thousand dollar payment
made at the beginning of the period and full redemption at the end of the
period. It reflects the change in unit value and a deduction of the contingent
deferred sales charge.

ADDITIONAL PERFORMANCE MEASURES

The performance figures discussed below may be calculated on the basis of the
historical performance of the Funds, and may assume that the Contracts were in
existence prior to the Inception Date (which they were not). Beginning the date
that the product became available to for sale to the public, actual Accumulation
Unit Values will be used for the calculations. Such Accumulation Unit Values
will be accompanied by the Standardized Average Annual Total Return described
above. The difference between the first set of additional performance measures,
PERCENTAGE CHANGE and ANNUALIZED RETURNS on Accumulation Unit Values, and the
second set, the NON-STANDARDIZED ANNUAL and AVERAGE ANNUAL TOTAL RETURNS, is
that the second set is based on specified premium patterns and includes the
deduction of the annual Administrative Charge, whereas the first set does not.
Additional details are described below.

ACCUMULATION UNIT VALUES: PERCENTAGE CHANGE AND ANNUALIZED RETURNS

MML Bay State will show the PERCENTAGE CHANGE in the value of an Accumulation
Unit for a Division of the Separate Account with respect to one or more periods.
The ANNUALIZED RETURN, or average annual change in Accumulation Unit Values, may
also be shown with respect to one or more periods. For a one year period, the
Percentage Change and the Annualized Return are effective annual rates of return
and are equal. For periods greater than one year, the Annualized Return is the
effective annual compounded rate of return for the periods stated. Since the
value of an Accumulation Unit reflects the Separate Account and Trust expenses
(see Table of Fees and Expenses), the Percentage Change and Annualized Returns
also reflect these expenses. These percentages, however, do not reflect the
annual Administrative Charge and the Sales Charge or premium taxes (if any),
which if included would reduce the percentages reported. For periods of less
than one year, the percentage change in accumulation unit value may be shown.

The NON-STANDARDIZED ANNUAL TOTAL RETURN and the NON-STANDARDIZED AVERAGE ANNUAL
TOTAL RETURN reflect a deduction for the annual Administrative Charge as well as
reflecting deductions for the Separate Account expenses and the expenses of the
Trusts. They are based on specified premium patterns which produce the resulting
Accumulated Values. They do not include Sales Charges or premium taxes (if any),
which would reduce the percentages reported.

The NON-STANDARDIZED ANNUAL TOTAL RETURN for a Division is the effective annual
rate of return that would have produced the ending Accumulated Value, as of the
stated one-year period.

The NON-STANDARDIZED AVERAGE ANNUAL TOTAL RETURN for a Division is the effective
annual compounded rate of return that would have produced the ending Accumulated
Value over the stated period had the performance remained constant throughout.

Note: The NON-STANDARDIZED ANNUAL TOTAL RETURN will be less than the NON-
STANDARDIZED ANNUALIZED RETURN on Accumulation Unit values for the same period
due to the effect of the annual Administrative Charge. Additionally, the
magnitude of this difference will depend on the size of the Accumulated Value
from which the


                                      24
<PAGE>
 
Annual Administrative Charge is deducted.

YIELD AND EFFECTIVE YIELD. MML Bay State may also show yield and effective yield
figures for the Money Market and Money Fund Divisions of the Separate Account.
"Yield" refers to the income generated by an investment in the Money Market and
Money Fund Divisions over a seven-day period, which is then "annualized". That
is, the amount of income generated by the investment during that week is assumed
to be generated each week over a 52-week period and is shown as a percentage of
the investment. The "effective yield" is calculated similarly but, when
annualized, the income earned by an investment in these divisions is assumed to
be re-invested. Therefore the effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment. These
figures will reflect a deduction for Fund, Separate Account, and certain
Contract level charges, and the Annual Administrative Charge assuming such
Contract remains in force. The Administrative Charge is based on a hypothetical
contract where such charge is applicable. These figures do not reflect the Sales
Charge or premium taxes, (if any), which if included would reduce the yields
reported.

The performance measures discussed above reflect results of the Funds and are
not intended to indicate or predict future performance. For more detailed
information, see the Statement of Additional Information.

Performance information for the Separate Account Divisions may be: (a) compared
to other variable annuity separate accounts or other investment products
surveyed by Lipper Analytical Services, Inc. a nationally recognized independent
reporting service or similar services that rank mutual funds and other
investment companies by overall performance, investment objectives and assets;
(b) tracked by other ratings services, companies, publications or persons who
rank separate accounts or other investment products on overall performance or
other criteria; and (c) included in data bases that produce reports and
illustrations by organizations such as CDA Weisenberger. Performance figures
will be calculated in accordance with standardized methods established by each
reporting service.

                        GENERAL INFORMATION AND HISTORY


                                 MML Bay State
                                 -------------

MML Bay State Life Insurance Company ("MML Bay State") is a corporation
established under the laws of Missouri. Formerly known as Western Life Insurance
Company of America, its name was changed to MML Bay State following the purchase
by Massachusetts Mutual Life Insurance Company ("MassMutual") of all of the
Company's issued and outstanding stock. MML Bay State is licensed to transact a
life, accident and health insurance business in all states except New York. As
of March 1, 1998, MML Bay State has obtained approval to write variable annuity
business in 45 states and the District of Columbia, and currently plans to seek
such authority in all states except for New York.
    
On June 30, 1997 MML Bay State was redomesticated from the State of Missouri to
the State of Connecticut. MML Bay State's Home Office is located in Hartford,
Connecticut.        

                            OppenheimerFunds, Inc.
                            ---------------------- 

OppenheimerFunds, Inc. ("OFI") is a corporation organized under the laws of the
state of Colorado. It has operated as an investment adviser since April 30,
1959. It (including a subsidiary) currently advises U.S. investment companies
with assets aggregating over $75 billion as of December 31, 1997, and having
over 3.5 million shareholder accounts. OFI is owned by Oppenheimer Acquisition
Corp., a holding company owned in part by senior management of OFI, and
ultimately controlled by MassMutual.

                               The Separate Account
                               --------------------
    
MML Bay State Variable Annuity Separate Account 1 (the "Separate Account") was
established as a separate investment account of MML Bay State on January 14,
1994, in accordance with the provisions of Chapter 309.376 of Missouri Statutes.
The Separate Account is registered as a unit investment trust under the
Investment Company Act of 1940. A unit investment trust is a type of investment
company which invests its assets in the shares of one or more management
investment companies rather than directly in its own portfolio of investment
securities. Registration under the Investment Company Act of 1940 does not
involve supervision of the management or investment practices or policies of the
Separate Account or of MML Bay State. As a result of MML Bay State's
redomestication to Connecticut on June 30, 1997, both MML Bay State and the
Separate Account are subject to regulation by the Insurance Department of the
State of Connecticut.       
    
The Separate Account is divided into fourteen Divisions (subject to state
availability). Four of the Divisions, MML Equity, MML Managed Bond, MML Blend,
and MML Money Market, invest in corresponding shares of MML Series Investment
Fund ("MML Trust"). The remaining ten Divisions, Oppenheimer Money, Oppenheimer
High Income, Oppenheimer Bond, Oppenheimer Capital Appreciation (This Division
will be known as the Oppenheimer Aggressive Growth Division once necessary
regulatory approvals are obtained.), Oppenheimer Growth, Oppenheimer Multiple
Strategies, Oppenheimer Global Securities, Oppenheimer Strategic Bond,
Oppenheimer Growth & Income, and subject to state availability, Oppenheimer
Small Cap Growth, invest in corresponding shares of Oppenheimer Variable Account
Funds (the "Oppenheimer Trust" and collectively with MML Trust, the "Trusts").
MML Bay State reserves the right to add additional divisions or separate
accounts. The value of both Accumulation Units (see The Accumulation (Pay-In)
Period section in the prospectus) and Annuity Units (see The Annuity (Pay Out)
Period section in the prospectus) in each Division reflects the investment
results of its underlying Fund.       

Although the assets of the Separate Account are assets of MML Bay State, assets
of the Separate Account equal to the reserves and other annuity contract
liabilities which depend on the investment performance of the Separate Account
are not chargeable with liabilities arising out of any other business MML Bay
State may conduct. The income and capital gains and losses, realized or
unrealized, of each Division of a Separate Account are credited to or charged
against such Division without regard to the income and capital gains and losses
of the other Divisions or other accounts of MML

Contracts (the "Contracts"), however, are general corporate obligations of MML
Bay State.

                                  The Trusts
                                  ----------

1.     The MML Trust
       -------------
    
The MML Trust is a no-load, open-end management investment company consisting of
six separate series of shares. The Separate Account invests in MML Equity Fund,
MML Money Market Fund, MML Managed Bond Fund, and MML Blend Fund (the "MML
Funds") each of which has its own investment objectives and policies. MassMutual
organized the MML Trust for the purpose of providing vehicles for the investment
of assets held in various separate investment accounts, including the Separate
Account, established by MassMutual or its life insurance company subsidiaries
such as MML Bay State. A statement of additional information concerning the MML
Trust is available upon request from the Service Center.       

2.     The Oppenheimer Trust
       ---------------------
     
The Oppenheimer Trust is a diversified open-end, investment company consisting
of the following funds: Oppenheimer Global Securities Fund, Oppenheimer High
Income Fund, Oppenheimer Money Fund, Oppenheimer Strategic Bond Fund,
Oppenheimer Aggressive Growth Fund (Prior to May 1, 1998, this Fund was called
Oppenheimer Capital Appreciation Fund.), Oppenheimer Multiple Strategies Fund,
Oppenheimer Bond Fund, Oppenheimer Growth Fund, Oppenheimer Growth & Income Fund
and subject to state availability, Oppenheimer Small Cap Growth Fund. Each of
these funds is available to Contract Owners. The Oppenheimer Trust was organized
for the purpose of providing funds to variable life and annuity contracts, and
exemptive relief permitting such sales has been obtained from the Securities and
Exchange Commission ("SEC"). Shares of the Trusts are not available to the
public. A statement of additional information concerning the Oppenheimer Trust
is available upon request from the Service Center.       

3.     General Information Concerning the Trusts
       -----------------------------------------
    
A Separate Account purchases and redeems shares of specified funds at their net
asset value without the imposition of any sales or redemption charge.
Distributions made on the shares of each Fund held by a Division of a Separate
Account are immediately reinvested in shares of a corresponding Fund at net
asset value, which shares are added to the assets of the appropriate Division of
the Separate Account. MassMutual serves as investment manager of each of the MML
Funds pursuant to separate investment management agreements executed by
MassMutual and each of the MML Funds. David L. Babson and Company, Inc.
("Babson"), a subsidiary of MassMutual, serves as the investment sub-adviser to
MML Equity Fund and the Equity Sector of the MML Blend Fund. Both MassMutual and
Babson are registered as investment advisers under the Investment Advisers Act
of 1940.       

OFI serves as investment adviser to the Funds of the Oppenheimer Trust. OFI is
registered as an investment adviser under the Investment Advisers Act of 1940.
The Prospectus and Statement of Additional Information for both the MML Trust
and the Oppenheimer Trust contain a description of their respective Funds, their
investment objectives, policies and restrictions, their expenses, the risks
attendant therein, and aspects of their operation.


                              Possible Conflicts
                              ------------------

1.     MML Trust
       ---------
    
Assets of registered variable life separate investment accounts of MassMutual
and its wholly-owned subsidiary, MML Bay State Life Insurance Company ("MML Bay
State") are invested in the MML Funds. Because registered variable annuity
separate investment accounts of MassMutual and MML Bay State are also invested
in the MML Funds, it is        


                                       3
<PAGE>
 
    
possible that material conflicts could arise between owners of the Contracts and
owners of variable life insurance policies funded by the various life separate
accounts. Possible conflicts could arise if: (i) state insurance regulators
should disapprove of or require changes in investment policies, investment
advisers or principal underwriters, or if MassMutual or MML Bay State should be
permitted to act contrary to actions approved by holders of the variable life
insurance policies under rules of the SEC; (ii) adverse tax treatment of the
Contracts or other variable contracts would result from using the same Funds;
(iii) different investment strategies would be more suitable for the Contracts
than for other variable contracts; or (iv) state insurance laws or regulations
or other applicable laws would prohibit the funding of variable annuity separate
accounts and variable life separate accounts by the same MML Funds. The Board of
Trustees of the MML Trust will follow monitoring procedures which have been
developed to determine whether material conflicts have arisen. Such Board will
have a majority of Trustees who are not interested persons of the MML Trust, and
determinations whether or not a material conflict exists will be made by a
majority of such disinterested Trustees. If a material irreconcilable conflict
exists, MassMutual and MML Bay State will take such action at their own expense
as may be required to cause MassMutual's and MML Bay State's variable life
separate accounts to be invested solely in shares of mutual funds which offer
their shares exclusively to variable life insurance separate accounts, unless,
in certain cases, the holders of both the variable life insurance policies and
the variable annuity contracts vote not to effect such segregation.      

2.     Oppenheimer Trust
       -----------------

The Oppenheimer Trust was established for use as an investment vehicle by
variable contract separate accounts such as the Separate Accounts. Accordingly,
it is possible that a material irreconcilable conflict may develop between the
interests of Contract Owners and other separate accounts investing in the
Oppenheimer Trust. The Board of Trustees of the Oppenheimer Trust (the "Board")
will monitor the Oppenheimer Funds for the existence of any such conflicts. If
it is determined that a conflict exists, the Board will notify MML Bay State and
appropriate action will be taken to eliminate such irreconcilable conflict. Such
steps may include: (1) withdrawing the assets allocable to some or all of the
separate accounts from the particular Oppenheimer Fund and reinvesting such
assets in a different investment medium, including (but not limited to) another
Oppenheimer Fund; (2) submitting the question to whether such segregation should
be implemented to a vote of all affected Contract Owners; and (3) establishing a
new registered management investment company or managed separate account.

                            Assignment of Contract
                            ---------------------- 

MML Bay State will not be charged with notice of any assignment of a Contract or
of the interest of any beneficiary or of any other person unless the assignment
is in writing and MML Bay State receives at its Service Center a true copy
thereof. MML Bay State assumes no responsibility for the validity of any
assignment.

While the Contracts are generally assignable, all non-tax qualified Contracts
must carry a non-transferability endorsement which precludes their assignment.
For qualified Contracts, the following exceptions and provisions should be
noted:
         
      (1) No person entitled to receive annuity payments under a Contract or
part or all of the Contract's value will be permitted to commute, anticipate,
encumber, alienate or assign such amounts, except upon the written authority of
the Contract Owner given during the Annuitant's lifetime and received in good
order by MML Bay State at its Service Center. To the extent permitted by law, no
Contract nor any proceeds or interest payable thereunder will be subject to the
Annuitant's or any other person's debts, contracts or engagements, nor to any
levy or attachment for payment thereof;
    
      (2) If an assignment of a Contract is in effect on the maturity date, MML
Bay State reserves the right to pay to the assignee in one sum the amount of the
Contract's maturity value to which he is entitled, and to pay any balance of
such value in one sum to the Contract Owner, regardless of any payment options
which the Contract Owner may have elected. Moreover, if an assignment of a
Contract is in effect at the death of the Annuitant or Owner prior to the
maturity date, MML Bay State will pay to the assignee in one sum, to the extent
that he or she is entitled, the death benefit available under the Contract.
Please consult The Death Benefit section of the prospectus for more information;
     

                                       4
<PAGE>
 
      (3) Contracts used in connection with annuity purchase plans adopted by
public school systems and certain tax-exempt organizations pursuant to Section
403(b) of the Code ("tax-sheltered annuities" or "TSAs") must be endorsed to
provide that they are non-transferable; and

      (4) Contracts issued under a plan for an Individual Retirement Annuity
pursuant to Section 408 of the Code must be endorsed to provide that they are
non-transferable. Such Contracts may not be sold, assigned, discounted, or
pledged as collateral for a loan or as security for the performance of an
obligation or for any other purpose by the Annuitant to any person or party
other than MML Bay State, except to a former spouse of the Annuitant in
accordance with the terms of a divorce decree or other written instrument
incident to a divorce.

Assignments may be subject to federal income tax.

                        RESTRICTIONS ON REDEMPTION

Redemptions of TSAs may be restricted as required by Section 403(b) (11) of the
Internal Revenue Code (see, "Tax- Sheltered Annuity Redemption Restrictions" in
the prospectus for details). In restricting any such redemption, MassMutual
relies on the relief from sections 22(e), 27(c) and 27(d) of the Investment
Company Act of 1940 granted in American Council of Life Insurance [1988 Transfer
Binder] Fed. Sec. L. Rep (CCH) 78,904 (November 22, 1988) (the "No Action
Letter"). In relying on such relief, MassMutual hereby represents that it
complies with the provisions of paragraphs (1) - (4) as set forth in the No
Action Letter.

The financial statements of the Separate Account and the statutory financial
statements of MML Bay State included in this Statement of Additional Information
have been included herein in reliance on the reports of Coopers & Lybrand
L.L.P., Springfield, Massachusetts 01101, independent accountants, given on the
authority of that firm as experts in accounting and auditing. Coopers &
Lybrand's report on the statutory financial statements of MML Bay State includes
explanatory paragraphs relating to the use of statutory accounting practices
rather than generally accepted accounting principles.      

                           Distribution and Administration
                           -------------------------------

MML Distributors, LLC ("MML Distributors"), a wholly-owned subsidiary of
MassMutual, is the principal underwriter for the contract pursuant to an
Underwriting and Servicing Agreement among MML Bay State, MML Distributors and
the Separate Account. MML Investors Services, Inc. ("MMLISI"), also a
wholly-owned subsidiary of MassMutual, serves as co-underwriter for the
Contract.

MML Distributors may enter into selling agreements with other broker-dealers
which are registered with the SEC as broker-dealers under the Securities
Exchange Act of 1934 and are members of the National Association of Securities
Dealers, Inc. ("selling brokers"). The Contract is sold through agents who are
licensed by state insurance department officials to sell the Contract. These
agents are also registered representatives of selling brokers or MMLISI. The
Contract will be offered on a continuous basis in certain states where MML Bay
State has the authority to write variable annuity business and the Contract has
been approved.
    
Pursuant to the Underwriting and Servicing Agreement, both MML Distributors and
MMLISI will receive compensation for their activities as underwriters for each
Separate Account. Compensation paid to MMLISI in 1997 was $15,000. Compensation
paid to MML Distributors in 1997 was $53,750. Commissions will be paid through
MMLISI and MML Distributors to agents and selling brokers for selling the
Contracts. During 1997, 1996 and 1995, such payments amounted to $8,762,111,
$10,362,608, and $2,899,557 respectively.

An Administration Agreement among MassMutual, MML Bay State, ALLIANCE-ONE
Services, L.P. ("ALLIANCE- ONE") and the Separate Account exists pursuant to
which ALLIANCE-ONE has agreed to provide: all services required for the
administration of those Contracts which depend in whole or in part on the
investment performance of the Separate Account. Additionally, pursuant to such
Agreement, ALLIANCE-ONE will keep such other records as may be mandated by state
and federal laws and regulations. ALLIANCE-ONE will operate MML Bay State's
Service Center and will respond to Contract Owner inquiries concerning the
status of their Contracts through June 30, 1998. However, the Administrative
Agreement will terminate on June 30, 1998. Effective July 1, 1998, the contracts
will be administered at the Annuity Service Center, H564, P.O. Box 9067,
Springfield, MA 01102-9067.      
    
The offering of the Contracts is continuous.      

                     Purchase of Securities Being Offered
                     ------------------------------------     
    
Interests in the Separate Account are sold to Contract Owners as accumulation
units. Charges associated with such securities are discussed in the Charges and
Deductions Section of the prospectus for the Contract. The Contract does not
offer any special purchase plan or exchange program not discussed in the
prospectus. (For a discussion of instances when sales charges will be waived,
see Contingent Deferred Sales Charges Section of the prospectus.)      

            CONTRACT VALUE CALCULATIONS FOR AMOUNTS ALLOCATED TO AN
                   INVESTMENT DIVISION OF A SEPARATE ACCOUNT

                       The Accumulation (Pay-In) Period
                       --------------------------------  
              Valuation Date, Valuation Time and Valuation Period
              ---------------------------------------------------

Each day on which the net asset value of the shares of any of the Funds is
determined is a "Valuation Date." The value of shares of the Funds held in the
Separate Account is determined as of the "Valuation Time," which is the time of
the close of trading on the New York Stock Exchange (currently 4:00 p.m. New
York time) on a Valuation Date. A "Valuation Period" is the period, consisting
of one or more days, from one Valuation Time to the next succeeding Valuation
Time.

                            Accumulation Unit Value
                            -----------------------

The value of an Accumulation Unit (the "Accumulation Unit Value") for each
Division of the Separate Account will vary from Valuation Date to Valuation
Date. The initial Accumulation Unit Value for each Division was set at
$1.000000. The Accumulation Unit Value for each Division on any date thereafter
is equal to the product of the "Net Investment Factor" for that Division (as
defined below) for the Valuation Period which includes such date and the
Accumulation Unit Value for that Division on the preceding Valuation Date.

                 Purchase of Accumulation Units in a Division
                 --------------------------------------------
                             of a Separate Account
                             ---------------------

You may allocate purchase payments among the investment Divisions of the
Separate Account and to the Fixed Account, where available. At the end of each
Valuation Period MML Bay State will apply your purchase payment (after deducting
any applicable premium taxes) to each Separate Account Division that you have
allocated in order to purchase Accumulation Units of the designated Division(s).
These Accumulation Units will be used in determining the value of amounts in the
Separate Account credited to the Contract on or prior to the maturity date and
the amount of variable annuity benefits at maturity. The value of the
Accumulation Units in each Division will vary with and will reflect the
investment performance and expenses of that Division (which in turn will reflect
the investment performance of the corresponding Fund in which the assets of the
Division are invested), any applicable taxes and the applicable Asset Charge.

The Accumulation Unit Value is determined as of the Valuation Time. Provided
that the Contract application is complete, Accumulation Units are purchased at
their Accumulation Unit Value within two days of the date a purchase

                                       6
<PAGE>
 
payment is received in good order at the Service Center. If the date of receipt
is not a Valuation Date, or if the purchase payment is received after the
Valuation Time or other than by mail or wire transfer, the value of the
Accumulation Units purchased will be determined within two days of the next
Valuation Time following the date the payment is received. If an initial
purchase payment is not applied within five business days after receipt (due to
incomplete or ambiguous Application information, for example) the payment amount
will be refunded unless specific consent to retain the payment for a longer
period is obtained from the prospective purchaser. For subsequent purchase
payments, the Valuation Date will be the date which is on or next follows the
date of receipt.
    
Amounts allocated to a Fixed Account will earn interest at a Guaranteed Rate for
the Guarantee Period. If, however, a Contract Owner redeems amounts held in the
Fixed Account, or transfers such sums before the Expiration Date of the selected
Accumulated Amount, such sums will be subject to a Market Value Adjustment
("MVA"). The application of the MVA may operate to provide a yield which is less
than the return generated pursuant to the Guarantee Rate. If an applicable
Segment is not available, then the formula used to calculate the Guaranteed Rate
available as of the effective date of the application of the MVA (referred to as
"j" in the formula described in the Market Value Adjustment section of the
prospectus) will be determined by interpolation or extrapolation of the
Guaranteed Rates for the Segments then available. (Please consult the prospectus
for the Fixed Account for more information).      
    
Net Investment Factor      
- ---------------------

The Net Investment Factor for each Division for any Valuation Period is equal to
the sum of the Gross Investment Rate for that Division (as defined below) for
the Valuation Period and 1.000000, decreased by the applicable Asset Charge.
The Net Investment Factor may be greater than or less than 1.000000.

                             Gross Investment Rate
                             ---------------------

The Gross Investment Rate for each Division of the Separate Account is equal to
the net earnings of that Division during the Valuation Period, divided by the
value of the net assets of that Division at the beginning of the Valuation
Period. The net earnings of the Division is equal to the accrued investment
income and capital gains and losses (realized and unrealized) of that Division
and an adjustment for taxes paid or provided for. The Gross Investment Rate will
be determined in accordance with generally accepted accounting principles and
applicable laws, rules and regulations. The Gross Investment Rate may be
positive or negative.

The policy of the Separate Account is to take dividends and capital gain
distributions on shares of the Funds held by the Separate Account in additional
shares and not in cash.

See the General Formulas section below for the general formulas which may be
        ----------------
used to compute the value of an Accumulation Unit for any Division of the
Separate Account, and for an explanation of how a hypothetical illustration
using such formulas may be developed. 

                         The Annuity (Pay-Out) Period
                         ----------------------------

When your Contract approaches its maturity date, you may choose to have the
Maturity Value of the Contract provide you at maturity with either Fixed Income
payments (referred to as the "Fixed Income Option" in your Contract), Variable
Monthly Income payments [referred to as the "Variable Monthly Income Option" in
your Contract], or a combination of the two. You also may elect to receive the
Maturity Value in one lump sum. Fixed or Variable Monthly Income payments may be
received under several different payment options. If you have made no election
within 30 days prior to the maturity date, the Contract will provide you with
the automatic payment of a Variable Monthly Income under a life income option
with payments guaranteed for 10 years.

                                 Fixed Income
                                 ------------

                                       7
<PAGE>
 
If you select a Fixed Income, then each annuity payment will be for a
fixed-dollar amount and will not vary with or reflect the investment performance
of the Separate Account or its Divisions. For further information regarding the
type of annuity benefit and the payment options available thereunder, you should
refer to your Contract.

                            Variable Monthly Income
                            -----------------------

If you select a Variable Monthly Income, then each annuity payment will be based
upon the value of the Annuity Units. This value will vary with and reflect the
investment performance of each Division to which Annuity Units are credited. The
number of Annuity Units will not vary, but will remain fixed during the annuity
period unless a Contract Owner makes transfers to another Division or a joint
and survivor Payment Option with reduced survivor income (as described in the
Prospectus). Variable Monthly Income payments will be made by withdrawal of
assets from the Separate Account.

                      Annuity Units and Monthly Payments
                      ----------------------------------

The number of Annuity Units in each Division to be credited to a Contract is
determined in the following manner. First, the value of amounts attributable to
a Contract for each Division of the Separate Account is determined by
multiplying the number of Accumulation Units credited to a Division on the
maturity date of the Contract by the Accumulation Unit Value of that Division on
the Payment Calculation Date for the first Variable Monthly Income payment. Such
value is then multiplied by the "purchase rate" (as defined below) to determine
the amount of the first Variable Monthly Income payment attributable to each
Division. Finally, the amount of the first Variable Monthly Income payment
attributable to each Division is divided by the Annuity Unit Value for that
Division on the Payment Calculation Date for such payment to determine the
number of Annuity Units for that Division.

The dollar amount of each Variable Monthly Income payment (other than the first
payment under a Contract) is equal to the sum of the products obtained by
multiplying the number of Annuity Units in each Division credited to the
Contract by their value (the "Annuity Unit Value") on the Payment Calculation
Date.

                                 Purchase Rate
                                 -------------  

The purchase rate for each Division is the amount of Variable Monthly Annuity
payment purchased by each $1,000 applied to that Division. The purchase rates
which will be applied will be those specified in the Contract or those in use by
MML Bay State when the first Variable Monthly Income payment is due, whichever
provides the higher income. The purchase rate will differ according to the
payment option elected. Such rate takes into account the age and year of birth
of the Annuitant or Annuitants. The sex of the Annuitant or Annuitants will also
be considered unless the Contract is issued on a unisex basis, including cases
issued in connection with an employer-sponsored plan covered by the United
States Supreme Court case of Arizona Governing Committee v. Norris. 
                             -------------------------------------

                             Assumed Investment Rates
                             ------------------------

The Assumed Investment Rate for each Separate Account Division will be 4% per
annum unless a lower rate is required by state law. The Assumed Investment Rate
will affect the amount by which Variable Monthly Income payments will vary from
month to month. If the actual net investment performance for a Division for the
period between the date any Variable Monthly Income payment is determined and
the date the next Variable Monthly Income payment is determined is equivalent on
an annual basis to an investment return at the Assumed Investment Rate, then the
amount of the next payment attributable to that Division will be equal to the
amount of the last payment. If such net investment performance for a Division is
equivalent to an investment return greater than the Assumed Investment rate, the
next payment attributable to that Division will be larger than the last; if such
net investment performance for a Division is equivalent to a return smaller than
the Assumed Investment Rate, then the next payment attributable to that Division
will be smaller than the last.

                              Annuity Unit Value
                              ------------------

The Annuity Unit Value for a Division depends on the Assumed Investment Rate and
on the Net Investment Factor for that Division. In 1994, the initial Annuity
Unit Value for each Division was set at $1.000000. An Annuity Unit Value for a
Division on any date thereafter is equal to the Net Investment Factor for the
Valuation Period which includes such date divided by the sum of 1.000000 plus
the rate of interest for the number of days in such Valuation Period at an
effective annual rate equal to the Assumed Investment Rate, and multiplied by
the Annuity Unit Value for the Division on the preceding Valuation Date.

               and Annuity Unit Value Using Hypothetical Example
               -------------------------------------------------

The above computations may be illustrated by the following hypothetical example:
Assume that the net earnings of the Division for the Valuation Period were
$11,760; that the value of net assets at the beginning of the Valuation Period
was $30,000,000; that the Asset Charge was .000038 per day; that the values of
an Accumulation Unit and an Annuity Unit in the Division of the Separate Account
on the preceding Valuation Date were $1.135000 and $1.067000, respectively, that
the corresponding Assumed Investment Rate was 4% and that the Valuation Period
was one day.

The Gross Investment Rate for the Valuation Period would be .000392 ($11,760
divided by $30,000,000). The Net Investment Factor would be 1.000354 (.000392
plus 1.000000 minus .000038). The new Accumulation Unit Value would be $1.1354
($1.135000 x 1.000354). At an effective annual rate of 4%, the rate of interest
for one day is .000107, and the new Annuity Unit Value would be $1.0673
($1.067000 x 1.000354 divided by 1.000107).

              Payments for a Contract Using Hypothetical Example      
              --------------------------------------------------

The above computations may be illustrated by the following hypothetical example:
Assume that 35,000 Accumulation Units in a Division of the Separate Account were
to be applied; that the purchase rate for the Assumed Investment Rate and
payment option elected was $5.65 per $1,000; that the Accumulation Unit Value of
such Division on the Payment Calculation Date for the first Variable Monthly
Income payment was $1.350000; and that the Annuity Unit Value of such Division
on the Payment Calculation Date for the first Variable Monthly Income was
$1.200000 and for the second Variable Monthly Income payment was $1.20050.

The first Variable Monthly Income payment would be $266.96 (35,000 X 1.350000 X
 .005650). The number of Annuity Units of such Division credited would be 222.467
($266.96 divided by $1.200000). The amount of the second Variable Monthly Income
payment would be $267.07 (222.467 X $1.200500). If the Contract has Annuity
Units credited in more than one Division of a Separate Account, the above
computation would be made for each Division and the Variable Monthly Income
Payment would be equal to the sum thereof.

                             PERFORMANCE MEASURES

MML Bay State may show the performance for the Divisions of the Separate Account
in the following ways:

                       Standardized Average Annual Total Return
                       ---------------------------------------- 
    
MML Bay State will show the "SEC Average Annual Total Return," formulated as
prescribed by the rules of the SEC, for each Division of the Separate Account
which has been in existence for more than one year. The Standardized Average
Annual Total Return is the effective annual compounded rate of return that would
have produced the cash redemption value over the stated period had the
performance remained constant throughout. The calculation assumes a single
$1,000 payment made at the beginning of the period and full redemption at the
end of the period. It reflects a deduction for the contingent deferred sales
charge, the annual Administrative Charge and all other Fund, Separate Account
and Contract level charges except premium taxes, if any. The annual
administrative charge will be apportioned among the Divisions of the Separate
Account based upon the percentages of in force Contracts investing in each of
the Divisions. For any Division which has been in existence for less than one
year, MML Bay State will show the aggregate total return as permitted by the
SEC. This aggregate total return will reflect the change in unit value and a
deduction for the contingent deferred sales charge. The Company may choose to
show Standardized Average Annual Total Returns based on inception of the
underlying Fund.      
    
For Divisions of the Separate Account which have been in existence for less than
one year, MML Bay State will show the aggregate total return as permitted by the
SEC. The aggregate total return assumes a single one thousand dollar payment
made at the beginning of the period and full redemption at the end of the
period. It reflects the change in unit value and a deduction of the contingent
deferred sales charge.

                        Additional Performance Measures
                        -------------------------------      
    
The performance figures discussed below, may be calculated on the basis of the
historical performance of the Funds, and may assume the Contracts were in
existence prior to their inception date, (which they were not). Beginning the
date the Contracts became available, actual Accumulation Unit values are used
for the calculations. These returns may be based on specified premium patterns
which produce the resulting Accumulated Values. They reflect a deduction for the
Separate Account expenses, MML Trust expenses, Oppenheimer Trust expenses, and
the annual Administrative Charge. They do not include contingent deferred sales
charges or premium taxes (if any), which if included would reduce the
percentages reported.      

The difference between the first set of additional performance measures,
ANNUALIZED RETURNS on Accumulation Unit Values, and the second set, the
NON-STANDARDIZED ANNUAL and AVERAGE ANNUAL TOTAL RETURNS, is that the second set
includes the deduction of the annual Administrative Charge, whereas the first
set does not.
    
                           ACCUMULATION UNIT VALUES
                              ANNUALIZED RETURNS      
    
The ANNUALIZED RETURN, or average annual change in Accumulation Unit values, may
be shown with respect to one or more periods. For one year, the Annualized
Return is the effective annual rate of return. For periods greater than one
year, the Annualized Return will be the effective annual compounded rate of
return for the periods stated. Since the value of an Accumulation Unit reflects
the expenses of the Separate Account and Trust (See Table of Fees and Expenses
of the Prospectus), the Annualized Returns also reflect these expenses. These
percentages, however, do not reflect contingent deferred sales charge or premium
taxes (if any), which if included would reduce the percentages that MML Bay
State reports.

* This Division will be known as the Oppenheimer Aggressive Growth Division

The NON-STANDARDIZED ANNUAL TOTAL RETURN and the NON-STANDARDIZED AVERAGE ANNUAL
TOTAL RETURN reflect a deduction for the Annual Administrative Charge as well as
reflecting deductions for the Separate Account expenses and the expenses of the
Trusts. They are based on specified premium patterns which produce the resulting
Accumulated Values. They do not include Sales Charges or premium taxes (if any),
which would reduce the percentages reported.

The NON-STANDARDIZED ANNUAL TOTAL RETURN for a Division of the Separate Account
is the effective annual rate of return that would have produced the ending
Accumulated Value of the stated one-year period had the division been in
existence.

         

The NON-STANDARDIZED AVERAGE ANNUAL TOTAL RETURN for a Division of the Separate
Account is the effective annual compounded rate of return that would have
produced the ending Accumulated Value over the stated period had the performance
remained constant throughout.

Note: The NON-STANDARDIZED ANNUAL TOTAL RETURN will be less than the
NON-STANDARDIZED ANNUALIZED RETURN on Accumulation Unit values for the same
period due to the effect of the annual Administrative Charge. Additionally, the
magnitude of this difference will depend on the size of the Accumulated Value
from which the annual Administrative Charge is deducted.

The performance figures discussed above reflect historical results of the Funds
and are not intended to indicate or to predict future performance.
    
Performance information for the Separate Account Divisions may be: (a) compared
to other variable annuity separate accounts or other investment products
surveyed by Lipper Analytical Services, Inc. a nationally recognized independent
reporting service or similar services that rank mutual funds and other
investment companies by overall performance, investment objectives and assets;
(b) tracked by other ratings services, companies, publications or persons who
rank separate accounts or other investment products on overall performance or
other criteria; and (c) included in data bases that can be used to produce
reports and illustrations by organizations such as CDA Wiesenberger. Performance
figures will be calculated in accordance with standardized methods established
by each reporting service.

                           YIELD AND EFFECTIVE YIELD
    
MML Bay State may show yield and effective yield figures for the MML Money
Market and Oppenheimer Money Divisions of the Separate Account. "Yield" refers
to the income generated by an investment in either money market Division over a
seven-day period, which is then "annualized." That is, the amount of income
generated by the investment during that week is assumed to be generated each
week over a 52-week period and is shown as a percentage of the investment. The
"effective" yield is calculated similarly but, when annualized, the income
earned by an investment in a money market division is assumed to be re-invested.
Therefore the effective yield will be slightly higher than the yield because of
the compounding effect of this assumed reinvestment.      

These figures will reflect a deduction for Fund, Separate Account, and certain
Contract level charges and the Annual Administrative Charge assuming such
contract remains in force. The Administrative Charge is based on a hypothetical
contract where such charge is applicable. These figures do not reflect the Sales
charge or premium taxes (if any), which if included would reduce the yields.

The following tables show the 7-day Yield and Effective Yield for the MML Money
Market Division and the Oppenheimer Money Division of the Separate Account for
the periods ended December 31, 1997:

Report Of Independent Accountants

To the Contract Owners of MML Bay State Variable Annuity Separate Account I
and the Board of Directors of MML Bay State Life Insurance Company

We have audited the accompanying statements of assets and liabilities of MML Bay
State Variable Annuity Separate Account I (comprising, respectively, the MML
Equity Division, MML Money Market Division, MML Managed Bond Division, MML Blend
Division, Oppenheimer Money Division, Oppenheimer High Income Division,
Oppenheimer Bond Division, Oppenheimer Capital Appreciation Division,
Oppenheimer Growth Division, Oppenheimer Multiple Strategies Division,
Oppenheimer Global Securities Division, Oppenheimer Strategic Bond Division and
Oppenheimer Growth & Income Division - the "Divisions") as of December 31, 1997,
the related statements of operations for the year then ended, and the statements
of changes in net assets for each of the two years in the periods then ended.
These financial statements are the responsibility of management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
verification of investments owned as of December 31, 1997, by examination of the
records of MML Series Investment Fund and by confirmation with Oppenheimer
Variable Account Funds. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of each of the respective
Divisions constituting MML Bay State Variable Annuity Separate Account I as of
December 31, 1997, the results of their operations for the year then ended, and
the changes in their net assets for each of the two years in the period then
ended, in conformity with generally accepted accounting principles.

MML Bay State Variable Annuity Separate Account 1

Notes To Financial Statements

1.  HISTORY

    MML Bay State Variable Annuity Separate Account 1 ("Separate Account 1") is
    a separate investment account established on January 14, 1994 by MML Bay
    State Life Insurance Company ("MML Bay State"). MML Bay State is a
    wholly-owned subsidiary of Massachusetts Mutual Life Insurance Company
    ("MassMutual"). Separate Account 1 operates as a registered unit investment
    trust pursuant to the Investment Company Act of 1940 and the rules
    promulgated thereunder.

    On November 15, 1994, MML Bay State paid $60,000 to provide the initial
    capital for Separate Account 1's twelve initial divisions: 14,099 shares
    were purchased in the two management investment companies described in Note
    2.

    On July 5, 1995, MML Bay State paid $5,000 to establish Separate Account 1's
    thirteenth division: 500 shares were purchased in the Growth & Income
    Division of the Oppenheimer Variable Account Fund described in Note 2.

2.  INVESTMENT OF THE SEPARATE ACCOUNT 1 ASSETS

    Separate Account 1 maintains thirteen divisions. Each division invests in
    corresponding shares of either MML Series Investment Trust ("MML Trust") or
    Oppenheimer Variable Account Funds ("Oppenheimer Trust").

    MML Equity Fund, MML Money Market Fund, MML Managed Bond Fund and MML Blend
    Fund are four series of shares of MML Trust. The MML Trust is a registered,
    no-load, open-end, management investment company for which MassMutual serves
    as investment manager. Concert Capital Management, Inc. ("Concert") served
    as the investment sub-adviser to MML Equity Fund and the Equity Sector of
    the MML Blend Fund from 1993-1996. Concert merged with and into David L.
    Babson and Company, Inc. ("Babson") effective December 31, 1996. At such
    time, both Concert and Babson were wholly-owned subsidiaries of DLB
    Acquisition Corporation, which is a controlled subsidiary of MassMutual.
    Thus, effective January 1, 1997, Babson serves as the investment sub-advisor
    to MML Equity Fund and the Equity Sector of the MML Blend Fund.

    Oppenheimer Money Fund, Oppenheimer High Income Fund, Oppenheimer Bond Fund,
    Oppenheimer Capital Appreciation Fund, Oppenheimer Growth Fund, Oppenheimer
    Multiple Strategies Fund, Oppenheimer Global Securities Fund, Oppenheimer
    Strategic Bond Fund and Oppenheimer Growth & Income Fund (the "Oppenheimer
    Funds") are the nine separate funds of the Oppenheimer Trust. The
    Oppenheimer Trust is a registered, open-end, diversified management
    investment company for which OppenheimerFunds, Inc. ("OFI"), a controlled
    subsidiary of MassMutual, serves as investment adviser (Prior to January 5,
    1996, OFI was known as Oppenheimer Management Corporation.)

    In addition to the thirteen divisions of Separate Account 1, a
    contractowner, in certain states, may also allocate funds to the Fixed
    Account. Proceeds from the Fixed Account will be deposited in a non-unitized
    segment of MML Bay State's general account organized as a separate account
    for accounting purposes. The interests in the Fixed Account are registered
    under the Securities Act of 1933.

3.  SIGNIFICANT ACCOUNTING POLICIES

    The following is a summary of significant accounting policies followed
    consistently by Separate Account 1 in preparation of the financial
    statements in conformity with generally accepted accounting principles.

A.  Investment Valuation

    Investments in the MML Trust and the Oppenheimer Trust are each stated at
    market value which is the net asset value of each of the respective
    underlying funds.

B.  Accounting for Investments

    Investment transactions are accounted for on trade date and identified cost
    is the basis followed in determining the cost of investments sold for
    financial statement purposes. Dividend income is recorded on the ex-dividend
    date.

Notes To Financial Statements (Continued)

C.  Federal Income Taxes

    Operations of Separate Account 1 form a part of the total operations of MML
    Bay State, and Separate Account 1 is not taxed separately. MML Bay State is
    taxed as a life insurance company under the provisions of the 1986 Internal
    Revenue Code, as amended. Separate Account 1 will not be taxed as a
    "regulated investment company" under Subchapter M of the Internal Revenue
    Code. Under existing federal law, no taxes are payable on investment income
    and realized capital gains attributable to Contracts which depend on
    Separate Account 1's investment performance. Accordingly, no provision for
    federal income tax has been made. MML Bay State may, however, make such a
    charge in the future if an unanticipated change of current law results in a
    company tax liability attributable to Separate Account 1.

D.  Annuity Reserve

    Annuity reserves are developed by using accepted actuarial methods and are
    computed using the 1983 Annuity Table a, with Projection Scale G. Separate
    Account 1 has an annuity reserve of $146,238 at December 31, 1997.

E.  Estimates

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the financial
    statements and the reported amounts of revenues and expenses during the
    reporting period. Actual results could differ from those estimates.

4.  CHARGES

    An asset charge is computed against the net asset value of Separate Account
    1's assets ("Net Asset Value"). The asset charge is currently equivalent on
    an annual basis to 1.40% of the Net Asset Value. The mortality and expense
    risk part of this charge is made daily at an annual rate which is currently
    equal to 1.15%, and will not exceed 1.25% of the Net Asset Value. The
    administrative expense part of the charge is made daily at an annual rate of
    0.l5%. The third component of the asset charge is a charge of 0.10% of the
    Net Asset Value assessed to reimburse MML Bay State for the cost of
    providing the enhanced death benefit under the contract. MML Bay State also
    charges for administrative costs and may impose a contingent deferred sales
    charge and a premium tax charge upon redemption, maturity or annuitization.

5.  DISTRIBUTION AGREEMENTS

    Effective May 1, 1996, MML Distributors, LLC ("MML Distributors"), a
    wholly-owned subsidiary of MassMutual, serves as principal underwriter of
    the contracts pursuant to an underwriting and servicing agreement among MML
    Distributors, MML Bay State and Separate Account I. MML Distributors is
    registered with the Securities and Exchange Commission (the "SEC") as a
    broker-dealer under the Securities Exchange Act of 1934 and is a member of
    the National Association of Securities Dealers, Inc. (the "NASD"). MML
    Distributors may enter into selling agreements with other broker-dealers who
    are registered with the SEC and are members of the NASD in order to sell the
    contracts.

    Prior to May 1, 1996, MML Investors Services, Inc. ("MMLISI") a wholly-owned
    subsidiary of MassMutual, served as principal underwriter of the contracts.
    Effective May 1, 1996, MMLISI serves as co-underwriter of the contracts
    pursuant to underwriting and servicing agreements among MMLISI, MML Bay
    State and Separate Account I. MMLISI is registered with the SEC as a
    broker-dealer under the Securities Exchange Act of 1934 and is a member of
    the NASD. Registered representatives of MMLISI sell the contracts as
    authorized variable life insurance agents under applicable state insurance
    laws.

Report Of Independent Accountants     
    
To the Board of Directors and Policyholders of     
MML Bay State Life Insurance Company

We have audited the accompanying statutory statements of financial position of
MML Bay State Life Insurance Company as of December 31, 1997 and 1996, and the
related statutory statements of income, changes in capital stock and surplus,
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As described more fully in Note 1, these financial statements were prepared in
conformity with statutory accounting practices of the National Association of
Insurance Commissioners and the accounting practices prescribed or permitted by
the Department of Insurance of the State of Connecticut, and prior to June 30,
1997, the Department of Insurance of the State of Missouri (collectively
"statutory accounting principles"), which practices differ from generally
accepted accounting principles. The effects on the financial statements of the
variances between the statutory basis of accounting and generally accepted
accounting principles, although not reasonably determinable at this time, are
presumed to be material.

In our opinion, because of the effects of the matter discussed in the preceding
paragraph, the financial statements referred to above do not present fairly, in
conformity with generally accepted accounting principles, the financial position
of MML Bay State Life Insurance Company at December 31, 1997 and 1996, or the
results of its operations or its cash flows for each of the three years in the
period ended December 31, 1997.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of MML Bay State Life Insurance
Company at December 31, 1997 and 1996, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1997, on
the statutory basis of accounting described in Note 1.

Notes To Statutory Financial Statements
    
1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION     

MML Bay State Life Insurance Company ("the Company") is a wholly-owned
subsidiary of Massachusetts Mutual Life Insurance Company ("MassMutual"). The
Company is primarily engaged in the sale of flexible and limited premium
variable whole life insurance and variable annuities distributed through career
agents. On March 1, 1996, the operations of Connecticut Mutual Life Insurance
Company were merged into MassMutual.

The accompanying statutory financial statements, except as to form, have been
prepared in conformity with the statutory accounting practices of the National
Association of Insurance Commissioners ("NAIC") and the accounting practices
prescribed or permitted by the Department of Insurance of the State of
Connecticut, and prior to June 30, 1997, the Department of Insurance of the
State of Missouri. On June 30, 1997, the Company redomesticated from the state
of Missouri to the state of Connecticut which did not have any effect on the
accounting practices being followed.

The accompanying statutory financial statements are different in some respects
from GAAP financial statements. The more significant differences are as follows:
(a) acquisition costs, such as commissions and other costs directly related to
acquiring new business, are charged to current operations as incurred, whereas
under GAAP these expenses would be capitalized and recognized over the life of
the policies; (b) policy reserves are based upon statutory mortality and
interest requirements without consideration of withdrawals, whereas GAAP
reserves would be based upon reasonably conservative estimates of mortality,
morbidity, interest and withdrawals; (c) bonds are generally carried at
amortized cost whereas GAAP generally requires they be valued at fair value; (d)
deferred income taxes are not provided for book-tax timing differences as would
be required by GAAP; and (e) payments received for universal life products and
variable annuities are reported as premium revenue, whereas under GAAP, these
payments would be recorded as deposits to policyholders' account balances.

The NAIC is currently engaged in an extensive project to codify statutory
accounting principles ("Codification") with a goal of providing a comprehensive
guide of statutory accounting principles for use by insurers in all states. This
comprehensive guide, which has not been approved by the NAIC or any state
insurance department, includes seventy-two Statements of Statutory Accounting
Principles ("SSAPs") and is expected to be effective no earlier than January 1,
1999. The effect of adopting these SSAPs shall be reported as an adjustment to
surplus on the effective date. Management is currently reviewing the impact of
Codification. However, since the SSAPs have not been finalized, the ultimate
impact cannot be determined at this time.

The preparation of statutory financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, as well as disclosures of contingent assets and liabilities, at the
date of the statutory financial statements. Management must also make estimates
and assumptions that affect the amounts of revenues and expenses during the
reporting period. Future events, including changes in the levels of mortality,
morbidity, interest rates and asset valuations, could cause actual results to
differ from the estimates used in the statutory financial statements.
    
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES     

The following is a description of the Company's principal accounting policies
and practices.

A.  Investments

Bonds are valued in accordance with rules established by the National
Association of Insurance Commissioners. Generally, bonds are valued at amortized
cost.

Policy loans are carried at the outstanding loan balance less amounts unsecured
by the cash surrender value of the policy.

Short-term investments are stated at amortized cost, which approximates fair
value.

In compliance with regulatory requirements, the Company maintains an Asset
Valuation Reserve and an Interest Maintenance Reserve. The Asset Valuation
Reserve and other investment reserves stabilize surplus against declines in the
value of bonds.

                                       26
<PAGE>
 
Notes To Statutory Financial Statements (Continued)

The Interest Maintenance Reserve captures after-tax realized capital gains and
losses which result from changes in the overall level of interest rates for all
types of fixed income investments and amortizes these capital gains and losses
into income using the grouped method over the remaining life of the investment
sold or over the life of the underlying asset. Net realized after tax capital
losses of $0.1 million in 1997 and 1996 and net realized after tax capital gains
of $0.3 million in 1995 were charged to the Interest Maintenance Reserve.
Amortization of the Interest Maintenance Reserve into net investment income
amounted to $0.1 million in 1997, 1996 and 1995. The Interest Maintenance
Reserve is included in other liabilities on the statutory Statement of Financial
Position.

Realized capital gains and losses, less taxes, not includable in the Interest
Maintenance Reserve, are recognized in net income. Realized capital gains and
losses are determined using the specific identification method. Unrealized
capital gains and losses are included in surplus.

B.  Separate Accounts

Separate account assets and liabilities represent segregated funds administered
and invested by the Company for the benefit of variable annuity and variable
life insurance policyholders. Assets, consisting of holdings in an open-end
series investment fund affiliated with MassMutual, bonds, common stocks, and
short-term investments, are reported at fair value. The transfer due from
separate account represents the policyholders' account values in excess of
statutory benefit reserves. Premiums, benefits and expenses of the separate
accounts are reported in the Statutory Statement of Income. The Company receives
compensation for providing administrative services to the separate account and
for assuming mortality and expense risks in connection with the policies. The
Company had $3.4 million and $3.0 million of its assets invested in the separate
account as of December 31, 1997 and 1996, respectively.

Net transfers to separate accounts of $479.4 million, $356.1 million, and $59.8
million in 1997, 1996 and 1995, respectively, are included in the addition to
policyholders' reserves, funds and separate accounts.

C.  Policyholders' Reserves

Policyholders' reserves for life contracts were developed using accepted
actuarial methods computed principally on the net level premium method and the
Commissioners' Reserve Valuation Method using the 1958 and 1980 Commissioners'
Standard Ordinary mortality tables with assumed interest rates ranging from 3.5
to 5.5 percent. Reserves for individual annuities are based on accepted
actuarial methods, principally at interest rates ranging from 5.5 to 6.0
percent.

During 1994, actuarial guidelines requiring additional reserves for immediate
payment of claims became effective. While the Company's aggregate reserves were
sufficient, the reserves for certain products were not recorded. The effect of
correctly recording these reserves was $1.3 million at December 31, 1994 and was
recorded as an adjustment to surplus during 1995.

D.  Premium and Related Expense Recognition

Premium revenue is recognized annually on the anniversary date of the policy.
Annuity premium is recognized when received. Commissions and other costs related
to issuance of new policies, maintenance and settlement costs, are charged to
current operations when incurred.

E.  Cash and Short-Term Investments

For purposes of the Statutory Statement of Cash Flows, the Company considers all
highly liquid short-term investments purchased with a maturity of twelve months
or less to be cash and short-term investments.

3. CAPITAL STOCK AND SURPLUS     

The Board of Directors of MassMutual has authorized the contribution of funds to
the Company sufficient to meet the capital requirements of all states in which
the Company is licensed to do business. Substantially all of the statutory
capital stock and surplus is subject to dividend restrictions relating to
various state regulations which limit the payment of dividends without prior
approval. Under these regulations, $7.5 million of capital stock and surplus is
available for distribution to the shareholder in 1998 without prior regulatory
approval.
    
4. RELATED PARTY TRANSACTIONS     

MassMutual and the Company have an agreement whereby MassMutual, for a fee, will
furnish the Company, as required, operating facilities, human resources,
computer software development and managerial services. Fees incurred under the
terms of the agreement were $26.8 million, $16.4 million and $6.6 million in
1997, 1996 and 1995, respectively.

The Company had reinsurance agreements with MassMutual in which MassMutual
assumed specific plans of insurance on a coinsurance basis and on a yearly
renewal term basis. The coinsurance agreement was terminated in 1995. A
termination fee of $6.2 million was recorded as an expense and paid to
MassMutual for the right to retain future fees and charges on the reinsurance
business. Premium income and policy benefits and payments are stated net of
reinsurance. Premium income of $5.1 million, $3.8 million and $29.6 million was
ceded to MassMutual in 1997, 1996 and 1995, respectively. Death benefits of $5.5
million, $3.1 million and $1.8 million were ceded to MassMutual in 1997, 1996
and 1995, respectively.

The Company entered into a stop-loss agreement with MassMutual on January 1,
1997, with maximum coverage at $25.0 million, under which the Company cedes
claims which, in aggregate exceed 18% of the covered volume for any year. For
1997, this limit was $15.4 million and it was not exceeded. The Company paid
approximately $1.0 million in premiums under the agreement in 1997.

During 1996, MassMutual contributed additional paid in capital of $25.0 million
cash to the Company and purchased an additional 2,500 shares of common stock for
$0.5 million.
    
5. FEDERAL INCOME TAXES     

The provision for federal income taxes is based upon the Company's best estimate
of its tax liability. No deferred tax effect is recognized for temporary
differences that may exist between financial reporting and taxable income.
Accordingly, the reporting of miscellaneous temporary differences, such as
reserves and acquisition costs, resulted in effective tax rates which differ
from the statutory tax rate.

The Company plans to file its 1997 federal income tax return on a consolidated
basis with its parent, MassMutual and MassMutual's other eligible life and
non-life affiliates. The Company and its eligible life and non-life affiliates
are subject to a written tax allocation agreement which allocates the group's
tax liability for payment purposes. Generally, the agreement provides that loss
members shall be compensated for the use of their losses and credits by other
members.

The Internal Revenue Service has completed examining MassMutual's income tax
returns through the year 1992 and is currently examining the Company for the
years 1993 and 1994. The Company believes any adjustments resulting from such
examinations will not materially affect its statutory financial statements.

The Company made federal tax payments of $10.9 million in 1997, $12.8 million in
1996 and $1.9 million in 1995.

limit concentration in any asset class, geographic region, industry group,
economic characteristic, investment quality or individual investment.

Notes To Statutory Financial Statements (Continued)

Proceeds from sales and maturities of investments in bonds were $20.4 million
during 1997, $28.7 million during 1996 and $36.6 million during 1995. Gross
capital gains of $0.1 million in 1997, $0.1 million in 1996 and $0.5 million in
1995 and gross capital losses of $0.1 million in 1997, $0.1 million in 1996, and
$0.1 million in 1995 were realized on those sales, portions of which were
included in the Interest Maintenance Reserve. The estimated fair value of
non-publicly traded bonds is determined by the Company using a pricing matrix.

B.   Other

It is not practicable to determine the fair value of policy loans which do not
have a stated maturity.
    
7. LIQUIDITY     

The withdrawal characteristics of the policyholders' reserves and funds,
including separate accounts, and the invested assets which support them at
December 31, 1997 are illustrated below:

8. BUSINESS RISKS AND CONTINGENCIES     

Approximately 49% of the Company's premium revenue in 1997 was derived from
three customers and approximately 52% of the Company's premium revenue in 1996,
was derived from two customers.

The Company is subject to insurance guaranty fund laws in the states in which it
does business. These laws assess insurance companies amounts to be used to pay
benefits to policyholders and claimants of insolvent insurance companies. Many
states allow these assessments to be credited against future premiums. The
Company believes such assessments in excess of amounts accrued will not
materially affect its financial position, results of operations or liquidity. In
1997, the Company elected not to admit $0.1 million of guaranty fund premium tax
offset receivables relating to prior assessments.

The Company is involved in litigation arising in and out of the normal course of
its business. Management intends to defend these actions vigorously. While the
outcome of litigation cannot be foreseen with certainty, it is the opinion of
management, after consultation with legal counsel, that the ultimate resolution
of these matters will not materially affect its financial position, results of
operations or liquidity.
    
9. RECLASSIFICATIONS     

Certain 1996 and 1995 amounts have been reclassified to conform with the current
year presentation.

Item 28.      Indemnification      


                                      30
<PAGE>
 
              MML Bay State directors and officers are indemnified under its by-
              laws. No indemnification is provided with respect to any liability
              to any entity which is registered as an investment company under
              the Investment Company Act of 1940 or to the security holders
              thereof, where the basis for such liability is willful
              misfeasance, bad faith, gross negligence or reckless disregard of
              the duties involved in the conduct of office.

              Insofar as indemnification for liabilities arising under the
              Securities Act of 1933 may be permitted to directors, officers and
              controlling persons of MML Bay State pursuant to the foregoing
              provisions, or otherwise, MML Bay State has been advised that in
              the opinion of the Securities and Exchange Commission such
              indemnification is against public policy as expressed in the
              Securities Act of 1933, and is, therefore, unenforceable. In the
              event that a claim for indemnification against such liabilities
              (other than the payment by MML Bay State of expenses incurred or
              paid by a director, officer or controlling person of MML Bay State
              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, MML Bay State
              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 of 1933
              and will be governed by the final adjudication of such issue.

Dear Contract Owner:

READ YOUR CONTRACT CAREFULLY. We have used examples to explain some of the
provisions. These examples do not reflect the actual amounts or status of this
contract. As you read through the contract, remember the words "we," "us," and
"our" refer to MML Bay State Life Insurance Company.

We will pay the maturity benefit to the Payee when this contract matures if the
Annuitant and Owner are living at that time. If the Annuitant or Owner dies
before this contract matures, we will pay the death benefit to the Beneficiary
when due proof of the death is received at our Service Center. Either payment is
subject to the terms of this contract, which are contained on this and the
following pages.

For service or information on this contract, contact our Service Center.

YOU HAVE A RIGHT TO RETURN THIS CONTRACT. If you decide not to keep this
contract, return it within ten days after you receive it. It may be returned by
delivering or mailing it to our Service Center. Then, the contract will be as
though it had never been issued. We will promptly refund the accumulated value
of this contract on the date we receive it, plus any deductions made from the
purchase payments. 

Signed for MML Bay State Life Insurance Company at Springfield, Massachusetts.

Sincerely yours,

                                                    /s/ Thomas J. Finnegan. Jr.

                              President             Secretary


This Contract provides that:  Flexible purchase payments may be made, while the
                                Annuitant and Owner are living, to the date 
                                this contract matures. 
                              A death benefit is payable if the Annuitant or 
                                Owner dies before this contract matures.
                              A monthly life income is payable beginning on 
                                the date this contract matures if the Annuitant 
                                and Owner are living at that time.

This Contract is not participating. It does not provide for the payment of
dividends.

All values and payments based on the investment performance of the Separate
Account shown on the Schedule Page are variable and not guaranteed as to dollar
amount.

Contract Summary

This Summary briefly describes some of the major contract provisions. Since it
does not go into detail, the actual provisions will control. See those
provisions for full information and any limits that may apply. The "Where To
Find It" on the inside of the back cover shows where these provisions may be
found.

We will pay a maturity benefit if the Annuitant and Owner are living on the
maturity date and the contract is in force at that time. We will pay a death
benefit if the Annuitant or Owner dies before this contract matures and while it
is in force. "In force" means that the contract has not terminated. Since this
is a variable annuity contract, neither of these benefits is guaranteed as to
dollar amount. Instead, all values and benefits that depend on the investment
performance of the Separate Account shown on the Schedule Page are variable and
not guaranteed as to dollar amount.

Purchase payments for this contract are flexible. Therefore, after the first
purchase payment has been paid, there is no requirement that any specific amount
of purchase payment be made on any date. Instead, within the limits stated in
the contract, any amount may be paid on any date before the maturity date while
the Annuitant and Owner are living.

Rights available under this contract include the rights to:

      . Assign this contract;
      . Change the Owner, the Payee, or any Beneficiary; 
      . Redeem this contract; 
      . Make partial redemptions; 
      . Change the date this contract matures; 
      . Allocate purchase payments among the divisions of the Separate Account; 
        and 
      . Transfer values among the divisions of the Separate Account.

This contract also includes a number of Payment Options. These provide
alternative ways to pay the maturity value, the death benefit, or the amount
payable upon redemption of this contract.

                        Part 1.   The Basics Of This Contract

                        In this Part, we discuss some basic concepts that are
                        necessary to understand this contract.

The Parties Involved -  The Owner is the person who owns this contract, as 
Owner, Joint Owner,     shown on our records.
Annuitant, Beneficiary,
Irrevocable             A Joint Owner may be named on this contract. In this   
Beneficiary, Payee      case, the Owner and the Joint Owner will have equal and
                        undivided interest in this contract. While a Joint Owner
                        is named under this contract:                           

                             . All rights and benefits conditioned on the Owner
                               living are conditioned on both the Owner and the
                               Joint Owner living;

                             . Either the Owner or the Joint Owner may exercise
                               an Owner right with the consent, satisfactory to
                               us, of the other;

                             . All notices, any tax forms, and any other
                               mailings about this contract will be sent to the
                               Owner's mailing address; and

                             . Any benefit payable upon the death of the Owner
                               will be payable upon the death of the Owner or
                               the Joint Owner, whomever dies first.

                        The Annuitant is the person on whose life this contract
                        is issued. Payment of the maturity benefit will be made
                        if that person is living when this contract matures. The
                        Annuitant may be the Owner of this contract, or someone
                        else may be the Owner; in the latter case, payment of
                        the maturity benefit will be made if both the Annuitant
                        and Owner are living when this contract matures.

                        Example: You buy a contract on your own life and name
                                 yourself as Owner. In this case, you are both
                                 the Annuitant and Owner. If you buy a contract
                                 on your spouse's life and name yourself as
                                 Owner, then the Annuitant and Owner are
                                 different people.

                        A Beneficiary is any person named on our records to
                        receive death proceeds after the Annuitant or Owner
                        dies. There may be different classes of Beneficiaries,
                        such as primary and secondary. These classes set the
                        order of payment. There may be more than one Beneficiary
                        in a class.

                        Example: Debbie is named as primary (first) Beneficiary.
                                 Anne and Scott are named as Beneficiaries in
                                 the secondary class. If Debbie is alive when
                                 the Annuitant dies, she receives any death
                                 benefit. But if Debbie is dead and Anne and
                                 Scott are alive when the Annuitant dies, Anne
                                 and Scott receive any death benefit.

                        Any Beneficiary may be named an Irrevocable Beneficiary.
                        An Irrevocable Beneficiary is one whose consent is
                        needed to change the named Beneficiary. Also, this
                        Beneficiary must consent to the exercise of other
                        contract rights.

                        The Payee is the person named on our records to receive
                        the maturity benefit when this contract matures. The
                        Annuitant is the Payee unless the Owner names another
                        Payee.

Dates - Contract Date,  Two important dates shown on the Schedule Page are the
Contract Anniversary    Contract Date and the Issue Date.
Date, Contract Year,
Issue Date, Maturity    The Contract Date is the starting point for determining
Date                    Contract Anniversary Dates and Contract Years. The first
                        Contract Anniversary Date is one year after the Contract
                        Date. The period from the Contract Date to the first
                        Contract Anniversary Date, or from one Contract
                        Anniversary Date to the next, is called a Contract Year.

                        Example: The Contract Date is June 10, 19X1. The first
                                 Contract Anniversary Date is June 10, 19X2. The
                                 period from June 10, 19X1, through June 9,
                                 19X2, is a Contract Year.

                        The Issue Date is used to determine the start of the
                        contestability period. We discuss contestability below.

                        Another important date shown on the Schedule Page is the
                        maturity date. This is the date the maturity benefit is
                        payable unless an earlier or later maturity date is
                        elected (see Part 4). The maturity benefit will be
                        payable only if this contract is in force and the
                        Annuitant and Owner are living on the maturity date.

This Is A Legal         This annuity is a legal contract between the Owner and
Contract                us. The entire contract consists of the application and
                        the annuity, which includes any riders. We have issued
                        this contract in return for the application and the
                        payment of the first purchase payment. Any change or
                        waiver of its terms must be in writing and signed by our
                        Secretary or an Assistant Secretary to be effective.

Trusts And Other        We are not responsible for carrying out the terms of any
Agreements              trust or other agreement that is not a part of this
                        contract. Our only responsibility is to perform
                        according to the terms of this contract.

Representations And     We rely on all statements made by or for the Annuitant
Contestability          in the application. Legally, these statements are
                        considered to be representations and not warranties. We
                        can bring legal action to contest the validity of this
                        contract for any material misrepresentation of a fact.
                        To do so, however, the misrepresentation must have been
                        in the application for this contract and a copy of the
                        application must have been attached to this contract
                        when issued.

                        In the absence of fraud, we cannot contest the validity
                        of this contract after it has been in force during the
                        lifetime of the Annuitant for two years from its Issue
                        Date.

Misstatement Of Age Or  One of the questions in the application concerns the
Sex                     Annuitant's date of birth; another concerns the
                        Annuitant's sex. If the sex or date of birth given is
                        not correct, all benefits and amounts payable under this
                        contract will be what would have been provided if the
                        correct sex and date of birth had been given.

                        No life income payments will be made until we have
                        received satisfactory proof of the Annuitant's sex and
                        date of birth at our Service Center.

Meaning Of In Force     "In force" means that this contract has not terminated.
                        This contract is in force from its Issue Date or, if
                        later, the date the first purchase payment is paid.
                        Subject to the Right To Terminate Contract provision in
                        Part 2, payment of future purchase payments is not
                        required to continue this contract in force.

Service Center          All service for this contract is provided through our
                        Service Center. The mailing address and telephone number
                        of our Service Center are shown on the Schedule Page. We
                        will send written notice of any change in this
                        information.

Contract State          This contract shall be construed according to the laws
                        of the state in which it was delivered.

                        currency of the United States of America. All monetary
                        amounts shown in this contract are in U.S. dollars.

                        Part 2.   Purchase Payments

                        Purchase payments are the amounts that may be paid to us
                        under this contract. Purchase payments for this contract
                        are discussed in this Part.

The First Purchase      The first purchase payment for this contract is due on
Payment                 the Contract Date. This contract will not be in force
                        until the first purchase payment has been paid to us.
<PAGE>
 
Purchase Payment        After the first purchase payment has been paid and     
Flexibility             subject to the Right To Terminate Contract provision,  
                        payment of additional purchase payments is not required
                        to continue the contract in force. Instead, any amount 
                        may be paid at any time before the maturity date while 
                        the Annuitant and Owner are living. However, no purchase
                        payment can be less than $100 without our consent.      

                        We have the right to set a maximum limit on the total
                        amount of purchase payments that may be made under this
                        contract. Any such limit will not be less than $500,000.

Right To Terminate      We have the right to terminate this contract if: 
Contract
                                . No purchase payment has been made for at least
                                  two consecutive years measured from the date
                                  we received the last purchase payment; and
                                . Each of the following amounts is less than
                                  $2,000 on the date we send notice of our
                                  election to terminate this contract: (1)The
                                  accumulated value of this contract:
                                  (1) The accumulated value of this contract
                                      (see Part 3) less any premium tax we would
                                      deduct on redemptions;
                                  (2) The cash redemption value (see Part 4);
                                      and
                                  (3) The sum of all purchase payments made into
                                      this contract less any partial redemption
                                      amounts.

                        If we exercise this right, we will mail a written notice
                        of termination to the Owner at the last known address
                        shown on our records. This notice will state that the
                        contract will terminate 30 days after we have mailed the
                        notice unless we receive a purchase payment that brings
                        the accumulated value (less any premium tax) to at least
                        $2,000 before that time.

                        If we terminate this contract, we will pay to the Owner
                        the greater of the amounts in items (1) and (2) above.

Where To Pay            All purchase payments are payable to us at our Service
                        Center. Upon request, a receipt signed by our Secretary
                        or an Assistant Secretary will be given for any purchase
                        payment made.

Net Purchase Payments   A net purchase payment is a purchase payment we receive
                        less any premium tax we deduct at that time.

Allocation Of Net       Each net purchase payment we receive will be allocated 
Purchase Payments       among the divisions of the Separate Account, as directed
                        in the application. This allocation will remain in     
                        effect until changed by any later election satisfactory
                        to us and received at our Service Center.               
                        
                        Part 3.   Separate Account, Values, And Charges

                        This contract provides that the accumulated value is
                        based on the investment performance of the Separate
                        Account and is not guaranteed as to dollar amount. This
                        Part gives information about the Separate Account and
                        the values and charges connected with it.

The Separate Account    The Separate Account shown on the Schedule Page is a
                        separate investment account we have established under
                        Missouri law. It is subject to the laws of the state in
                        which this contract was delivered.

                        The Separate Account has several divisions. Each
                        division invests in shares of an investment Fund. The
                        divisions are shown on the Schedule Page.

                        The values of the assets in the divisions are variable
                        and are not guaranteed. They depend on the investment
                        results of the Separate Account shown on the Schedule
                        Page.

                        We own the assets of the Separate Account. Those assets
                        will only be used to support variable annuities. A
                        portion of the assets equal to the reserves and other
                        liabilities of the Separate Account will not be charged
                        with liabilities that arise from any other business we
                        may conduct. However, we may transfer assets exceeding
                        the reserves and other liabilities of the Separate
                        Account to our general account. The income and capital
                        gains and losses, whether or not realized, from each
                        division of the Separate Account are credited to or
                        charged against that division without regard to any of
                        our other income and capital gains or losses. The assets
                        of the Separate Account are protected from the claims of
                        our creditors.

Changes In The          We have the right to establish both additional divisions
Separate Account        of the Separate Account and additional Separate Accounts
                        from time to time. Amounts credited to any additional  
                        divisions established would be invested in shares of   
                        other Funds. For any division, we have the right to    
                        substitute new Funds.                                   

                        Subject to applicable provisions of federal securities
                        laws, we have the right to change the investment policy
                        of any division of the Separate Account with the
                        approval of the Missouri Insurance Commissioner. If
                        required, evidence of the approval of a material change
                        by the Missouri Insurance Commissioner will be filed
                        with the insurance supervisory official of the state
                        where this contract is delivered. We will notify the
                        Owner if the Missouri Insurance Commissioner approves
                        any material change.

                        We have the right to withdraw availability of any
                        division of the Separate Account for future amounts
                        being credited. We will notify the Owner before we
                        withdraw any division of the Separate Account.

                        We have the right to operate the Separate Account as a
                        unit investment trust under the Investment Company Act
                        of 1940 or in any other form permitted by law.

Accumulation Units      Accumulation units are used to measure the variable   
And Annuity Units       values on or before the maturity date of this contract.
                        Annuity units are used to determine the amount of each
                        payment of Variable Monthly Income after those payments
                        have begun. The value of a unit is determined as of the
                        valuation time on each valuation date for valuation of
                        the Separate Account. The value of any unit can vary  
                        from valuation date to valuation date. That value     
                        reflects the investment performance of the division of
                        the Separate Account applicable to that unit. The value
                        of accumulation units and annuity units is discussed  
                        further in Part 7.                                     

Valuation Date,         A valuation date is any date the New York Stock Exchange
Valuation Time,         (or its successor) is open for trading. A valuation    
Valuation Period        period is the period of time from the end of one       
                        valuation date to the end of the next valuation date.  
                        The valuation time is the time of day the New York Stock
                        Exchange (or its successor) closes on a valuation date.
                        All actions to be performed on a valuation date will be
                        performed as of the valuation time.

                                . Maturity of the contract (see Part 5); 
                                . Death of the Annuitant or Owner (see Part 5); 
                                . Full or partial redemption (see Part 4); 
                                . Transfers of values from the division to any
                                  other divisions (see Part 4);
                                . Assessment of an administrative charge from
                                  the division (see Administrative Charge
                                  provision below in this Part); and        
                                . Assessment of a transfer fee from the division
                                  (see Transfer Fee provision below in this
                                  Part).

                        Amounts are credited to and taken from divisions of the
                        Separate Account by purchasing and selling accumulation
                        units. Accumulation units will be purchased and sold at
                        the unit value as of the valuation time on the valuation
                        date of purchase or sale. The number of units purchased
                        or sold will be the amount of money for purchase or sale
                        divided by that unit value.

                        Example: The amount applied is $550. The date of
                                 purchase is June 10, 19X4. The accumulation
                                 unit value on that date is $10. The number of
                                 units purchased would be 55 ($550 divided by
                                 $10 = 55). If, instead, the unit value was $11,
                                 then the amount applied would purchase 50 units
                                 ($550 divided by $11 = 50).

                        If a purchase payment, or a request that causes us to
                        purchase or sell accumulation units, is received by us
                        before the valuation time on a valuation date,
                        accumulation units will be purchased or sold as of that
                        valuation date. Otherwise, accumulation units will be
                        purchased or sold as of the next following valuation
                        date.

                        In no case will accumulation units be purchased or sold
                        before the Contract Date.

Accumulated Value Of    The value of the accumulation units credited to this  
Contract                contract in a division of the Separate Account is equal
                        to the accumulation unit value in that division on the
                        date the value is determined, multiplied by the number
                        of those units in that division.                       

                        The accumulated value of this contract on any date is
                        the total of the values of the accumulation units
                        credited to this contract in each division of the
                        Separate Account.

Administrative Charge   An administrative charge will be assessed each year on
                        the Contract Anniversary Date. An administrative charge
                        will also be assessed upon full redemption, death, or
                        maturity. In either case, however, we will not assess
                        the charge if the accumulated value of the contract at
                        that time is $50,000 or more.

                        The amount of the administrative charge will be
                        determined each year by us. However, it will not exceed
                        $50, or any lower limit required by law. Any
                        administrative charge assessed will be taken from all
                        divisions in the Separate Account on a pro rata basis,
                        based on the value of the accumulation units credited to
                        this contract in each division.

                        The administrative charge discussed in this provision is
                        in addition to any charge for administrative expenses
                        contained in the asset charge discussed in the Net
                        Investment Factor provision in Part 7.

Deductions For Sales    Sales charges are not deducted from purchase payments  
Charges                 when received by us. Instead, we may make deductions for
                        sales charges from amounts payable upon full or partial
                        redemption of this contract. We may also make deductions
                        for sales charges from the death benefit in certain    
                        cases. Finally, we may make deductions for sales charges
                        from the maturity value on the maturity date of this   
                        contract.                                               
                        
                        In certain situations, however, sales charges will not
                        apply. Sales charges will not be assessed on the
                        following amounts of purchase payments:

                             1. All amounts paid as death benefits due to the
                                Annuitant's death if the Annuitant's age on the
                                Contract Date (shown on the Schedule Page) is 75
                                or less;
                             2. The full amount if the Annuitant has not reached
                                age 59 1/2 and all proceeds from maturity or
                                full redemption of this contract are applied
                                under any one, or more than one, of the
                                following payment options:
                                  a. Variable Monthly Income Option B with
                                     payments for 10 years or more and
                                  b. Variable Monthly Income Options C, E, and
                                     F;

                               3. The full amount if the Annuitant has attained
                                  age 59 1/2 and all proceeds from maturity or
                                  full redemption of this contract are applied
                                  under any one, or more than one, of the
                                  following payment options:
                                        a. Fixed Income or Variable Monthly
                                           Income Option B with payments for 10
                                           years or more; and
                                        b. Fixed Income or Variable Monthly
                                           Income Options C, E, and F;
                               4. During any Contract Year: 
                                        a. Any amounts not yet redeemed for
                                           which the sales charge percentage
                                           (see Amount Of Sales Charge provision
                                           below) is 0%; and
                                        b. 10% of the amounts not yet redeemed
                                           for which the sales charge percentage
                                           is 1% or greater.

Amount Of Sales Charge  Sales charges are based on the purchase payments made
                        and the time that has passed since we received them.

                        The part of the sales charge related to a purchase
                        payment is a level percentage of that payment during
                        each year since it was paid. For each successive year,
                        the percentage decreases until it becomes zero. Sales
                        charge percentages for each purchase payment are shown
                        in the table below.


                          Year Since               Year Since        
                            Payment    Percentage    Payment          Percentage
                          ----------   ----------   ----------        ----------
                              1st          7%           5th               3%
                              2nd          6            6th               2
                              3rd          5            7th               1
                              4th          4            8th and later     0

                        Example: You make a $1,000 purchase payment on May 10,
                                 19X1. The part of the sales charge related to
                                 this purchase payment is:
                                      $70 from May 10, 19X1 through May 9, 19X2;
                                      $60 from May 10, 19X2 through May 9, 19X3;
                                       :
                                      $10 from May 10, 19X7 through May 9, 19X8;
                                      and $0 thereafter.

                        Subject to the limits stated above in the Deductions For
                        Sales Charges provision, the sales charge at any time is
                        based solely on the purchase payments assumed to be
                        redeemed at that time. In determining the sales charge,
                        we assume that purchase payments are redeemed in the
                        order in which they are paid. Any amounts in excess of
                        purchase payments are assumed to be redeemed last.

                        Example: You've made two purchase payments of $1,000
                                 each, one on May 10, 19X1, and the other on
                                 July 21, 19X4.

                                 You make your first request for a partial
                                 redemption on August 7, 19X5; it is for $800.
                                 The sales charge is based solely on the first
                                 $1,000 purchase payment, made in 19X1, since it
                                 exceeds the $800 requested. Since August 7,
                                 19X5, is during the 5th year since the purchase
                                 payment was made, the sales charge percentage
                                 is 3%. But a sales charge is assessed only on
                                 $600 (all but 10% of the $2,000 not yet
                                 redeemed). The sales charge is therefore $18
                                 (3% of $600), and you receive $782.

                                 You request a second partial redemption of $800
                                 on September 21, 19X8. The sales charge is
                                 based on the remaining $200 from the first
                                 purchase payment and on $600 from the second.
                                 The percentage for the first purchase payment
                                 is 0% (8th year since payment) and for the
                                 second is 3% (5th year since payment). But a
                                 sales charge is assessed only on $500 (none of
                                 the $200 not yet redeemed having a percentage
                                 of 0% and, on the $600, all but 10% of the
                                 $1,000 not yet redeemed having a percentage of
                                 1% or greater). The sales charge is then $15
                                 (3% of $500), and you receive $785.

                        Part 4.   Life Benefits

                        This variable annuity contract provides a maturity
                        benefit if the Annuitant and Owner are living on the
                        maturity date and the contract is in force at that time.
                        It provides a death benefit if the Annuitant or Owner
                        dies before the maturity date while the contract is in
                        force. There are other rights and benefits available
                        under this contract. These "Life Benefits" are discussed
                        in this Part.

                        Contract Ownership

Rights Of Owner         While the Annuitant is living, the Owner may exercise
                        all rights given by this contract or allowed by us.
                        These rights include assigning this contract, changing
                        Beneficiaries, changing ownership, enjoying all contract
                        benefits, and exercising all contract options. The
                        consent of any Irrevocable Beneficiary is needed to
                        exercise any contract right.

Assigning This Contract This contract may be assigned. But for any assignment to
                        be binding on us, we must receive a signed copy of it at
                        our Service Center. We will not be responsible for the
                        validity of any assignment.

                        Once we receive a signed copy, the rights of the Owner
                        and the interest of any Beneficiary or any other person
                        will be subject to the assignment.

Changing The Owner,     The Owner, the Payee, or the Beneficiary may be changed
Payee, Or Beneficiary   while the Annuitant is living. We do not limit the
                        number of changes that may be made. To make a change,
                        the Owner's written request, satisfactory to us, must be
                        received at our Service Center. The change will take
                        effect as of the date the request is signed, even if the
                        Annuitant or Owner dies before we receive it. Each
                        change will be subject to any payment we made or other
                        action we took before receiving the request.

Transfers Of Values     Transfers of values are subject to the limitations
                        stated in the Limitations On Transfers provision below.
                        Subject to those limitations, transfers of values may be
                        made upon direction, satisfactory to us, received at our
                        Service Center. These transfers are transfers of values
                        between divisions of the Separate Account. Before any
                        proceeds from this contract are applied to a payment
                        option, these transfers will be made by selling all or
                        part of the accumulation units in a division and
                        applying the value of the sold units to purchase units
                        in any other division. While payments are being made
                        under a Variable Monthly Income payment option, these
                        transfers will be made by exchanging all or part of the
                        annuity units in a division for a number of annuity
                        units in any other division that give the same amount of
                        monthly income as of the date of transfer.

                        An amount transferred from a division of the Separate
                        Account may be expressed in terms of either a dollar
                        amount or a whole-number percentage.

                        Transfers will be as of the valuation date specified in
                        the Purchase And Sale Of Accumulation Units provision in
                        Part 3. All transfers made on one date will be
                        considered one transfer.

Limitations On          The smallest amount that can be transferred from a
Transfers               division of the Separate Account is $500 or, if less,
                        the value of the accumulation units or annuity units
                        credited to this contract in that division.

                        We reserve the right to limit the number and frequency
                        of transfers allowed during any Contract Year.

                        Transfers cannot be made during the 30-day period ending
                        on the maturity date.

Transfer Fee            We reserve the right to assess a transfer fee of $20 for
                        each transfer of value in a Contract Year in excess of
                        four transfers.

                        If we assess a transfer fee, it will be assessed as of
                        the date of the transfer. Any transfer fee assessed will
                        be taken from the divisions of the Separate Account from
                        which the amounts are transferred.

                        Redeeming This Contract

Right To Redeem         This contract may be redeemed for its cash redemption
                        value, while the Annuitant and Owner are living, at any
                        time before it matures. Redemption will be effective on
                        the date we receive this contract and a written
                        redemption request, satisfactory to us, at our Service
                        Center. A later effective date may be elected in the
                        redemption request.

Cash Redemption Value   The cash redemption value on any date is the accumulated
                        value of this contract less any deductions for sales and
                        administrative charges and less any premium tax we
                        deduct at that time. The accumulated value of this
                        contract is described in Part 3.

Partial Redemptions     Partial redemptions may be made, while the Annuitant and
                        Owner are living, at any time before this contract
                        matures. The request must state the division (or
                        divisions) from which redemption will be made. Partial
                        redemptions will be made by selling a sufficient number
                        of accumulation units to provide the partial redemption
                        including any sales charge deduction that applies to
                        that redemption.

                        Any partial redemption will be subject to the limits set
                        forth below.

                             . Any partial redemption must be for at least $100.

                             . The accumulated value of the contract remaining
                               after a partial redemption must be at least
                               $1,000 plus any premium tax we would deduct at
                               that time on a full redemption.

When And How We Pay     Any partial redemption made will be paid in one sum.
                        However, if the entire contract is redeemed, the cash
                        redemption value may be paid in one sum or applied under
                        any payment option. See Part 6.

                        We will pay all redemptions within seven days after the
                        written request for the redemption is received by us at
                        our Service Center. However, this time period is subject
                        to any extension permitted under federal laws, rules,
                        and regulations applying to redemption of variable
                        annuity contracts.

                        Right To Change The Maturity Date

Electing An Early       Before this contract matures and while it is in force,
Maturity Date           the maturity date may be changed to any date that is
                        earlier than the maturity date then in effect. To elect
                        an earlier maturity date, we require that the Owner's
                        written election for the change be received at our
                        Service Center at least 30 days before the early
                        maturity date wanted.

Electing A Later        Before this contract matures and while it is in force,
Maturity Date           the maturity date may be changed to any date that is
                        later than the maturity date then in effect. However,
                        that later maturity date must be on or before the
                        Contract Anniversary Date nearest the Annuitant's 90th
                        birthday. To elect a later maturity date, the Owner must
                        send us written election to be received at our Service
                        Center within 90 days before the maturity date then in
                        effect. Any rider this contract has will be cancelled
                        when the change is made.

                        Other Provisions Regarding Life Benefits

Periodic Statements     While this contract is in force before the maturity
                        date, or the Annuitant's or Owner's death if earlier, we
                        will send a Status Report to the Owner at least
                        semiannually. This Report will show:

                             . The number of accumulation units in each division
                               of the Separate Account;
                             . The accumulation unit value in each division of
                               the Separate Account;
                             . The accumulated value of this contract; 
                             . The cash redemption value of this contract; and 
                             . Any other information required by applicable law.
<PAGE>
 
                        All this information will be as of a date not more than
                        45 days before the date the Status Report is mailed.

                        We will also give the Owner any other periodic reports,
                        containing information about this contract, that may be
                        required by federal or state law.

Receipt Of Information  Any directions, requests, or other information received
                        other than by mail at our Service Center after the time
                        set for valuation of the Separate Account will be deemed
                        to have been received the next day.


                        Part 5.   Maturity Benefit And Death Benefit

                        The maturity benefit is the payment we will make when
                        this contract matures if the Annuitant and Owner are
                        living at that time. The death benefit is the amount of
                        money we will pay when we receive due proof at our
                        Service Center that the Annuitant, or Owner if the
                        Annuitant is still living, has died before the contract
                        matures. These benefits are discussed in this Part.

                        Maturity Benefit

Maturity Value          The maturity value is the cash redemption value of this
                        contract on the maturity date.

Monthly Life Income     When this contract matures, the maturity value will be
                        applied to provide a monthly life income under Variable
                        Monthly Income Payment Option C, as described in Part 6.
                        This income will be based on the life of the Annuitant
                        and will be paid for the lifetime of the Annuitant. The
                        first payment is due on the maturity date. Future
                        payments will be due on the same day of the month as the
                        maturity date. The final payment will be the last one
                        due before the Annuitant's death.

                        There is a guarantee as to the first 120 income
                        payments. If the Annuitant dies before all these
                        payments are made, we will continue to make payments
                        until 120 income payments have been made.

                        The Owner may change the payment option at any time,
                        while the Annuitant is living, up to 30 days before the
                        maturity date.

Alternate Settlements   There are other settlements available when this contract
At Maturity             matures. That is, the Owner may elect to have the      
                        maturity value either applied under any other payment  
                        option discussed in Part 6 or paid in one sum.          

                        In any case, if an assignment of this contract is in
                        effect on the maturity date, we have the right to pay
                        the maturity value in one sum. Any amount due the
                        assignee will be paid to the assignee. The balance, if
                        any, will be paid to the Owner.

Restriction On Rights   The Annuitant cannot assign, transfer, or place any
                        restriction on this contract without the Owner's written
                        consent. No income payment under this contract can be
                        assigned, transferred, or taken in advance of its due
                        date, and the right to receive any income payments
                        cannot be restricted, without the Owner's written
                        consent. In any case, the Owner's written consent must
                        be given before the Annuitant dies and must be received
                        at our Service Center.

                        Death Benefit

Amount Of Death         The amount of the death benefit is determined as of the
Benefit                 date we receive due proof of death at our Service     
                        Center.

                                     -11-

                        If the death benefit is payable due to the death of the
                        Annuitant, the amount of the death benefit is the
                        greater of:

                             . The accumulated value of this contract less any
                               deduction for administrative charge (and any
                               sales charge if the Annuitant's age on the
                               Contract Date exceeds 75); and

                             . The accumulation at interest of all purchase
                               payments made less any partial redemption
                               amounts, but not more than twice the sum of
                               purchase payments less partial redemption
                               amounts. The effective annual rate of interest
                               used in this accumulation will be 5%% for any
                               period before the Annuitant's 75th birthday and
                               0%% thereafter.

                        In all cases, the amount of death benefit due to the
                        Annuitant's death is reduced by any premium tax we
                        deduct at that time.

                        If the Owner is not the Annuitant and the death benefit
                        is payable due to the death of the Owner, the amount of
                        the death benefit will be the cash redemption value of
                        this contract.

                        Interest On Maturity Or Death Benefit

Interest Payable        If the maturity value is paid in one sum after this
                        contract matures, we will add interest from the maturity
                        date to the date of payment. If the death benefit is
                        paid in one sum, we will add interest from the date
                        proof of death is received to the date of payment.

                        If the death benefit is applied under a payment option,
                        interest will be paid from the valuation date that is on
                        or next follows the date written notice of death is
                        received to the effective date of that option. It will
                        be paid in one sum to the Beneficiary living on the
                        effective date.

                        In all cases, the amount of interest payable on the
                        maturity value or death benefit will be the same as
                        would be paid under Option D of the payment options for
                        the applicable period of time. See Part 6 for a
                        description of Option D.

                        Part 6.   Payment Options

                        These are Optional Methods of Settlement. They provide
                        alternate ways in which payment can be made. This
                        contract provides Fixed Income payment options. It also
                        provides Variable Monthly Income payment options. These
                        two types of options are discussed below. Any other
                        payment option agreed to by us may be elected.

Fixed Income Payment    A Fixed Income payment option provides payments that are
Options                 guaranteed by us under our general account. The amounts
                        of these payments do not depend on the investment
                        performance of the Separate Account.

                        All the payment options described in this Part are
                        available on a Fixed Income basis. They are described in
                        terms of monthly payments. However, annual, semiannual,
                        or quarterly payments may be requested instead. The
                        amount of these payments will be determined in a way
                        that is consistent with monthly payments and will be
                        quoted on request.

Variable Monthly        A Variable Monthly Income payment option provides
Income Payment Options  payments that are not guaranteed as to dollar amount.
                        Instead, they are based on the investment performance of
                        the Separate Account. Payment options B, C, E, and F are
                        available on a Variable Monthly Income basis. Payment
                        can only be made monthly. The manner in which the dollar
                        amounts of Variable Monthly Income payments are computed
                        is set forth in Part 7.
<PAGE>
 
Availability Of         All or part of the death benefit, the maturity value, or
Payment Options         the cash redemption value may be applied under any     
                        payment option. If the contract is assigned, any amount
                        due to the assignee will be paid in one sum. The       
                        balance, if any, may be applied under any payment      
                        option.                                                 
                        
                        If the Schedule Page shows that this contract was issued
                        on a unisex rate basis, the female rates shown in the
                        Option C, E, and F Tables apply in all cases. The male
                        rates in those Tables do not apply to unisex-rate
                        contracts.

Minimum Amounts         If the amount to be applied under any option is less
                        than $2,000, we may pay that amount in one sum instead.
                        If payments under a Fixed Income option amount to less
                        than $20 each, we have the right to make payments at
                        less frequent intervals. If the first payment under a
                        Variable Monthly Income option amounts to less than $20,
                        we have the right to make a one-sum payment.

Option A                Level Income Payment Option (not available as a Variable
                        Monthly Income option). Monthly payments are level. The
                        amount of each payment may not be less than $10 for each
                        $1,000 applied. Interest will be credited each month on
                        the unpaid balance and added to it. This interest will
                        be at a rate determined by us, but not less than the
                        equivalent of 2 1/2% per year. Payments continue until
                        the amount we hold runs out. The last payment will be
                        for the balance only.

Option B                Fixed Time Payment Option (available as a Fixed Income
                        option and as a Variable Monthly Income option). For
                        either option, monthly payments will be made for any
                        period selected, up to 30 years. For Fixed Income Option
                        B, the monthly payments are level. They depend on the
                        total amount applied, the period selected, and the
                        monthly payment rates we are using when the first
                        payment is due. The rate for any payment will not be
                        less than shown in the Fixed Income Option B Table.

                        For Variable Monthly Income Option B, the payments are
                        not guaranteed as to amount and may vary during the
                        period selected. The Variable Income Option B Table
                        shows the first monthly payment for each $1,000 applied.

                             payment, multiply by 11.865.

Option C                Lifetime Payment Option. For Fixed Income Option C, the
                        monthly payments are level. For Variable Income Option
                        C, the payments are not guaranteed as to amount and may
                        vary. For either option, the payments are based on the
                        life of a named person. Payments will continue for the
                        life of that person. The three variations are :

                        (1) Payments for life only (available as a Fixed Income
                        option and as a Variable Monthly Income option). No
                        specific number of payments is guaranteed. Payments stop
                        when the named person dies.

                        (2) Payments guaranteed for amount applied (not
                        available as a Variable Monthly Income option). Payments
                        stop when they equal the amount applied or when the
                        named person dies, whichever is later. "Amount applied"
                        means the dollar amount used to provide the income.

                        (3) Payments guaranteed for 5, 10, or 20 years
                        (available as a Fixed Income option and as a Variable
                        Monthly Income option). Payments stop at the end of the
                        selected guaranteed period or when the named person
                        dies, whichever is later.

                        The Fixed Income Option C Table shows the minimum
                        monthly payment for each $1,000 applied. The Variable
                        Monthly Income Option C Table shows the minimum amount
                        of the first monthly payment for each $1,000 applied.
                        The actual payments will be based on the monthly payment
                        rates we are using when the first payment is due. They
                        will not be less than shown in the Table.

Option D                Interest Payment Option (not available as a Variable
                        Monthly Income option). We will hold any amount applied
                        under this option. Interest on the unpaid balance will
                        be paid each month at a rate determined by us. This rate
                        will not be less than the equivalent of 2 1/2% per
                        year.

Option E                Joint Lifetime Payment Option (available as a Fixed
                        Income option and as a Variable Monthly Income option).
                        For Fixed Income Option E, the monthly payments are
                        level. For Variable Income Option E, the payments are
                        not guaranteed as to amount and may vary. For either
                        option, the payments are based on the lives of two named
                        persons. While both are living, one payment will be made
                        each month. When one dies, payments continue for the
                        lifetime of the other. The two variations are:

                        (1) Payments for two lives only. No specific number of
                        payments is guaranteed. Payments stop when both named
                        persons have died.

                        (2) Payments guaranteed for 10 years. Payments stop at
                        the end of 10 years or when both named persons have
                        died, whichever is later.

                        The Fixed Income Option E Table shows the minimum
                        monthly payment for each $1,000 applied. The Variable
                        Monthly Income Option E Table shows the minimum amount
                        of the first monthly payment for each $1,000 applied.
                        The actual payments will be based on the monthly rates
                        we are using when the first payment is due. They will
                        not be less than shown in the Table.

Option F          Joint Lifetime Payment Option With Reduced Payments (available
                  as a Fixed Income option and as a Variable Monthly Income
                  option). Monthly payments are based on the lives of two named
                  persons. Payments will continue while both are living. When
                  one dies, reduced payments will continue for the lifetime of
                  the other. These reduced payments will be two-thirds of what
                  they would have been if both persons had continued to live.
                  Payments stop when both named persons have died.

                  The Fixed Income Option F Table shows the minimum monthly
                  payment for each $1,000 applied. The Variable Monthly Income
                  Option F Table shows the minimum amount of the first monthly
                  payment for each $1,000 applied. The actual payments will be
                  based on the rates we are using when the first payment is due.
                  They will not be less than shown in the Table.

Electing A Payment       To elect any option, we require that a written request,
Option                   satisfactory to us, be received at our Service Center.
                         The Owner may elect an option during the Annuitant's
                         lifetime. If the death benefit is payable in one sum
                         when the Annuitant dies, the Beneficiary may elect an
                         option with our consent.

                         Options for any amount payable to an association,
                         corporation, partnership, or fiduciary are available
                         with our consent. However, a corporation or partnership
                         may apply any amount payable to it under Option C, E,
                         or F if the option payments are based on the life or
                         lives of the Annuitant, the Annuitant's spouse, any
                         child of the Annuitant, or any other person agreed to
                         by us.

Effective Date And       The effective date of an option is the date the amount
Payment Date             is applied under that option. For a death benefit, this
                         is the date that due proof of the Annuitant's or
                         Owner's death is received at our Service Center. For a
                         maturity value, it is the date the contract matures.
                         For the cash redemption value, it is the effective date
                         of redemption.
<PAGE>
 
                         The first payment is due on the effective date, except
                         that the first payment under Option D is due one month
                         later. A later date for the first payment may be
                         requested in the payment option election. All payment
                         dates will fall on the same day of the month as the
                         first one. No payment will become due until a payment
                         date. No part payment will be made for any period
                         shorter than the time between payment dates.

                         Example: Monthly payments are being made to your son on
                                  the 1st of each month. He dies on the 10th. No
                                  part payment is due your son or his estate for
                                  the period between the 1st and the 10th.

Withdrawals And          If provided in the payment option election, all or part
Changes                  of the unpaid balance under Options A and D may be
                         withdrawn or applied under any other option.

                         If provided in the payment option election, the
                         commuted value of the future payments under Variable
                         Monthly Income Option B may be withdrawn. In this case,
                         the number of annuity units that Variable Monthly
                         Income Option B has in each division of the Separate
                         Account will be commuted at the Assumed Investment
                         Rate. The commuted units in each division will be
                         multiplied by the annuity unit value for that division
                         on the date the commuted value is determined. The
                         commuted value will be the sum of the values determined
                         for each division less any deduction for sales charges
                         that applies.

                         A deduction for sales charges will apply only if:

                              . No sales charges were deducted when the
                                redemption or maturity value was applied under
                                Variable Monthly Income Option B; and 
                              . A deduction for sales charges would be made if
                                this contract was redeemed or matured in one sum
                                on the date commutation is made; and 
                              . Commutation is made during the lifetime of the
                                person receiving the Option B payments.

                         The amount of the sales charge deduction will be the
                         same as if this contract was redeemed for an amount
                         equal to the commuted value (before deduction of the
                         sales charge) on the date commutation is made.

Income Protection        To the extent permitted by law, each option payment and
                         any withdrawal shall be free from legal process and the
                         claim of any creditor of the person entitled to them.
                         No option payment and no amount held under an option
                         can be taken or assigned in advance of its payment
                         date, unless the Owner's written consent is given
                         before the Annuitant dies. This consent must be
                         received at our Service Center.

                         Part 7.   Notes On Our Computations

                         This Part covers some technical points about this
                         contract.

Net Investment Factor    For each division of the Separate Account, the Net
                         Investment Factor for any valuation period is the gross
                         investment rate for that period plus 1.000000 and minus
                         an asset charge. This asset charge will be not more
                         than .0000411 for each day of a valuation period. The
                         Net Investment Factor may be greater or less than
                         1.000000.

                         For each division of the Separate Account, the gross
                         investment rate for any valuation period is equal to:

                              . The net earnings of that division during the
                                valuation period, divided by 
                              . The value of the total assets of that division
                                at the beginning of the valuation period.

                                     -21-

                         The net earnings of each division are equal to the
                         accrued investment income and capital gains and losses
                         (realized and unrealized) of that division reduced by
                         any amount charged against that division for taxes paid
                         or reserved for by us. The gross investment rate will
                         be determined by us in accordance with generally
                         accepted accounting principals and applicable laws,
                         rules, and regulations. This determination shall be
                         conclusive upon the Owner, the Annuitant, any
                         Beneficiary, and any assignee and any other person
                         under this contract.

Accumulation Unit        The value of an accumulation unit in each division was
Value                    set at $1.000000 on the first valuation date selected
                         by us. The value on any date thereafter is equal to the
                         product of the Net Investment Factor for that division
                         for the valuation period that includes that date and
                         the value of the corresponding accumulation unit value
                         on the preceding valuation date.

Annuity Unit Value       All annuity unit values in each division were set at
                         $1.000000 on the first valuation date selected by us.
                         The value on any date thereafter is equal to (a) the
                         Net Investment Factor for that division for the
                         valuation period that includes that date divided by (b)
                         the sum of 1.000000 and the rate of interest for the
                         number of days in the valuation period, computed at an
                         effective annual rate equal to the Assumed Investment
                         Rate, and multiplied by (c) the corresponding annuity
                         unit value on the preceding valuation date.

Assumed Investment       The Assumed Investment Rate is the annual interest rate
Rate                     assumed in determining the first payment under each of
                         the Variable Monthly Income payment options. The amount
                         of each subsequent payment from each division of the
                         Separate Account will depend on the relationship
                         between the Assumed Investment Rate and the actual
                         investment performance of that division. The Assumed
                         Investment Rate will be 4% per annum. If a 4% rate
                         would result in a first Variable Monthly Income payment
                         larger than that permitted under applicable state law,
                         we will select a lower rate to comply with that law.

Adjustment Of Units      We have the right to split or consolidate the number of
And Values               accumulation units or annuity units credited to the
                         contract, with a corresponding increase or decrease in
                         the unit values. We may exercise this right whenever we
                         consider an adjustment of units to be desirable.
                         However, strict equity will be preserved in making any
                         adjustment. No adjustment will have any material effect
                         on the benefits, provisions, or investment return of
                         this contract, or on the Owner, Annuitant, any
                         Beneficiary, any assignee or other person, or on us.

Payment Calculation      Payments under a Variable Monthly Income payment option
Date                     are calculated on a payment calculation date. That date
                         is the earliest valuation date that is not more than 10
                         days before the due date of the payment.

Computing Variable       The first payment under a Variable Monthly Income
Monthly Income           payment option is computed in the following steps:
Payments          
                              (1) For each division, we multiply the proceeds
                                  from the division by the rate we are using for
                                  the payment option as of the date of the first
                                  payment.  
                              (2) For each division, we multiply the result of
                                  step (1) above by the ratio of the
                                  accumulation unit value for the division on
                                  the first payment calculation date (see
                                  Payment Calculation Date provision above) to
                                  the accumulation unit value of the division on
                                  the due date the first payment is due. 
                              (3) We sum the results of step (2) for all
                                  divisions of the Separate Account; this is the
                                  first payment.
 
                         Future payments under a Variable Monthly Income payment
                         option are measured by annuity units. The number of
                         annuity units in each division is the portion of the
                         first payment provided by that division divided by the
                         annuity unit value for that division on the first
                         payment calculation date.
<PAGE>
 
                         For payments after the first one, the annuity units in
                         each division are multiplied by the annuity unit value
                         on the payment calculation date that applies. The
                         payment to be made on the payment due date is the sum
                         of the amounts provided by each division.

Basis Of Computation     In computing the minimum payments under Fixed Income
                         payment options C, E, and F, we use mortality rates
                         from the 1983 Table a with Projection Scale G for 30
                         years and with female rates set back five years.

                         The Variable Monthly Income Option C, E, and F Tables
                         are based on mortality rates from the 1983 Table a,
                         with Projection Scale G, for annuitants born in 1942.
                         For all other years of birth, the mortality improvement
                         is determined by adjusting the annuitant's age
                         according to the following table:

Guarantees               All benefits, payments, and values under this contract
                         that depend on the investment performance of the
                         Separate Account may increase or decrease, as discussed
                         in this Part. However, we guarantee that the dollar
                         amounts of variable benefits will not be adversely
                         affected by variations of actual expenses from expense
                         charges stated in this contract. Also, those benefits
                         will not be adversely affected by variations in actual
                         mortality from the mortality assumptions stated in this
                         contract.

                         A part of the assets of the Separate Account is the
                         reserve for variable benefits and liabilities that
                         depend on the investment performance of that Account.

                         liabilities we have that arise from any business we
                         conduct that does not depend on the performance of that
                         Account.

Re:  Post-Effective Amendment No. 4 to Registration Statement
     No. 33-76920 filed on Form N-4

Ladies and Gentlemen:

This opinion is furnished in connection with the filing of Post-Effective
Amendment No. 4 to Registration Statement No. 33- 76920 on Form N-4 under the
Securities Act of 1933 for MML Bay State Life Insurance Company's ("MML Bay
State") flexible premium variable annuity contract (the "Contract"). MML Bay
State Variable Annuity Separate Account 1 issues the Contract.

As Attorney for MML Bay State, I provide legal advice to MML Bay State in
connection with the operation of its variable products. In such role I am
familiar with the Post-Effective Amendment for the Contract. In so acting, I
have made such examination of the law and examined such records and documents as
in my judgment are necessary or appropriate to enable me to render the opinion
expressed below. I am of the following opinion:

1. MML Bay State is a valid and subsisting corporation, operated under the laws
of the state of Connecticut and is subject to regulation by the Connecticut
Commissioner of Insurance.

2. MML Bay State Variable Annuity Separate Account 1 is a separate account
validly maintained by MML Bay State in accordance with Connecticut law.

3. All of the prescribed corporate procedures for the issuance of the Contract
have been followed, and all applicable state laws have been complied with.

I hereby consent to the use of this opinion as an exhibit to this Post-Effective
Amendment.

Very truly yours,

/s/ James M. Rodolakis
