Highlights

This prospectus describes the general provisions of the Flex-Annuity variable
annuity contracts. We offered the contracts for sale in tax-qualified
arrangements and non-tax qualified arrangements.

We no longer offer these contracts for sale to the public. Contract owners may
continue, however, to make purchase payments to their contract.


Free Look

You have a right to examine your contract. If you change your mind about owning
your contract, you can cancel it within 10 days after receiving it. When you
cancel the contract within this time period, we will not assess a contingent
deferred sales charge. You will receive back your contract value as of the
business day we receive your contract and written request at our Annuity Service
Center, plus any amount we deducted from your purchase payment(s). If your state
requires it, or if you purchase this contract as an IRA, we will return the
greater of your purchase payments less any withdrawals you took, or your
contract value, plus any amount we deducted from your purchase payment(s). In
some states, the period may be longer.


Contingent Deferred Sales Charge

We do not deduct a sales charge when we receive a purchase payment from you.
However, we may assess a contingent deferred sales charge if you withdraw any
part of or all of your contract value, or if on the maturity date of your
contract, you elect to receive fixed annuity payments or a lump sum payment.

The amount of the contingent deferred sales charge depends on:

 .     the amount of purchase payments you make and

 .     the length of time between when you make the purchase payments and when
      you withdraw the value of the accumulation units purchased with them, or
      when your contract reaches its maturity date and you elect to receive 
      fixed annuity payments or a lump sum payment.

The contingent deferred sales charge ranges from:

 .    11% to 0% on the value of the accumulation units purchased with your 
     first $3,000 of purchase payments,

 .    5% to 0% on the value of the accumulation units purchased with your
     cumulative purchase payments between $3,000 and $35,000, and 

 .    0% on the value of the accumulation units purchased with your cumulative
     purchase payments over $35,000.


Federal Income Tax Penalty

If you withdraw any of the contract value from your non-qualified contract, a
10% federal income tax penalty may be applied to the amount of the withdrawal
that is includible in your gross income for tax purposes. Some withdrawals may
be exempt from the penalty tax. They include any amounts: 

 .    paid on or after you reach age 59 1/2;

 .    paid to your beneficiary after you die;

 .    paid if you become totally disabled as the term is defined in the Internal
     Revenue Code;

 .    paid in a series of substantially equal payments made annually or more
     frequently for life or a period not exceeding life expectancy;

 .    paid under immediate annuity; or

 .    that come from purchase payments made prior to August 14, 1982.

The Internal Revenue Code (the Code) treats any withdrawal as first coming from
earnings and then from your purchase payments. Separate tax penalties and
restrictions apply to withdrawals under qualified contracts. Please refer to the
Taxes section of this prospectus for more information.

The Company

Massachusetts Mutual Life Insurance Company (MassMutual), 1295 State Street,
Springfield, Massachusetts, is a mutual life insurance company chartered in 1851
under the laws of Massachusetts. MassMutual is currently licensed to transact
life, accident, and health insurance business in all states, the District of
Columbia, Puerto Rico and certain provinces of Canada.
    
MassMutual had consolidated statutory assets in excess of $67 billion and
estimated total assets under management of $176.8 billion as of December 31,
1998.      


The Flex-Annuity Contracts 

General Overview 

Flex-Annuity is a contract between you, the owner and us, MassMutual. The
contracts are intended for retirement savings or other long-term investment
purposes. In exchange for your purchase payments, we agree to pay you an income
when you choose to receive it. You select the income period beginning on a date
you designate that is in the future. The Flex-Annuity contracts, like all
deferred annuity contracts, have two phases - the accumulation phase and the
income phase. Your contract is in the accumulation phase until you decide to
begin receiving annuity payments that begin on the maturity date. During the
accumulation phase we provide a death benefit. Once you begin receiving annuity
payments, your contract enters the income phase.

You are not taxed on contract earnings until you take money from your contract.
This is known as tax deferral.

The contracts are called variable annuities because you can choose to allocate
your purchase payment(s) among four funds. The amount of money you are able to
accumulate in your contract during the accumulation phase depends on the
investment performance of the funds you select.

At the beginning of the income phase, you can choose to receive annuity payments
on a variable basis, fixed basis or a combination of both. If you choose
variable payments, the amount of the annuity payments will fluctuate depending
on the investment performance of the funds you select for the income phase. If
you select to receive payments on a fixed basis, the payments you receive will
remain level.

Contracts issued by Separate Account 1 are designed for use in retirement plans
which qualify for special federal tax treatment under the Code. The following
are the types of plans for which the contracts are suitable: 

 .    pension and profit-sharing plans qualified under Section 401(a) or 403(a)
     of the Code, and participant-directed individual account plans under
     Section 404(c) of ERISA. These plans are sometimes referred to as ERISA
     Plans;

 .    annuity purchase plans adopted by public school systems and certain
     tax-exempt organizations pursuant to Section 403(b) of the Code. These
     plans are sometimes called "Tax Sheltered Annuities" or "TSAs";

 .    deferred compensation plans for state and local governments and tax-exempt
     organizations established under the provisions of Section 457 of the Code;
     and

 .    Individual Retirement Annuities established in accordance with Section 408
     of the Code. These are referred to as IRAs. This also includes IRA's under
     a Simplified Employee Pension Plan.

Contracts issued by Separate Account 2 were sold for use in retirement plan
arrangements other than the qualified plans offered through Separate Account 1.
These contracts are referred to as non-qualified.

                                                                               7

Ownership Of A Contract


Owner

The owner is named at time of application. The owner of the contract must be the
annuitant, except in the following situations where there is:

 .    a custodian for a minor annuitant under the Uniform Gifts or Transfers to
     Minors Act; 

 .    a non-natural person;

 .    a trust; or

 .    an employer sponsored plan.

As the owner of the contract, you exercise all rights under the contract. The
owner names the beneficiary. Subject to any requirements of the Code applicable
to your contract, you may change the owner of the contract at any time prior to
the maturity date by written request. Changing the owner may result in tax
consequences.

Participants under a qualified contract, except for TSAs and IRAs, may not be
the contract owner. Therefore, the participants have no ownership rights. Under
Section 457 deferred compensation plans, the state or political subdivision or
tax-exempt organization must be the contract owner.


Annuitant

The annuitant is the person on whose life we base annuity payments. The
annuitant was named when we issued your contract.


Beneficiary

The beneficiary is the person(s) or entity you name to receive any death benefit
You name the beneficiary at the time of application. Unless an irrevocable
beneficiary has been named, you can change the beneficiary at any time before
the annuitant dies. If an irrevocable beneficiary is named, this beneficiary
must consent to the exercise of any contract rights.

You can name different classes of beneficiaries, such as primary or secondary.
These classes set the order of payment. There may be more than one beneficiary
in a class.

Purchase Payments


How Contracts Were Purchased

The minimum initial purchase payment was:

 .    $600 divided by the number of installments (not mote than 12) which you
     expected to make each year; or

 .    $2,000, if you intended to make only one purchase payment over the lifetime
     of the contract.

You can make additional purchase payments to your contract of at least $25.

We reserve the right to establish a maximum on the total purchase payments you
may make to your contract This maximum will be at least $500,000.

You may make additional purchase payments by:
    
 .    mailing your check that clearly indicates your name and contract number to
     our lockbox:      

     MassMutual VA
     P.O. Box 92714
     Chicago, IL 60675-2714

 .    instructing your bank to wire transfer funds to:

     Chase Manhattan Bank, New York, New York
     ABA #021000021
     MassMutual Account #910-2-517290
     Ref: VA Income Contract #
     Name:  (Your Name)

We have the right to reject any purchase payment.


Allocation Of Purchase Payments

If you make additional purchase payments, we will apply them in the same way as
you requested on your application, unless you tell us otherwise. We will credit
these amounts to your contract on the business day we receive them at our
lockbox or Annuity Service Center. Our business day closes when the New York
Stock Exchange closes, usually 4:00 p.m. Eastern time. If we receive your
purchase payment at our lockbox or Annuity Service Center on a non-business day
or after the business day closes, we will credit the amount to your contract
effective the next business day.

                                                                               9

Investment Choices


The Separate Accounts

We established two separate accounts:

Massachusetts Mutual Variable Annuity Separate Account 1 (Separate Account 1)
and Massachusetts Mutual Variable Annuity Separate Account 2 (Separate Account
2). We established these separate accounts to hold the assets that underlie the
contracts. We established Separate Account 1 for qualified contracts on April 8,
1981, and Separate Account 2 for non-qualified contracts on October 14, 1981. We
have registered both separate accounts with the Securities and Exchange
Commission as unit investment trusts under the Investment Company Act of 1940.

We own the assets of the separate accounts. However, those separate account
assets equal to the reserves and other contract liabilities are not chargeable
with liabilities arising out of any other business we may conduct. All the
income, gains and losses (realized or unrealized) resulting from these assets
are credited to, or charged against, the contracts and not against any other
contracts we may issue.

We have divided each separate account into 4 divisions. Each of these divisions
invests in a fund. You bear the complete investment risk for purchase payments
that you allocate to a fund.


The Funds

The contract offers the 4 funds listed below.

MML Series Investment Fund ("MML Trust")
    
MML Trust is a no-load, open-end, investment company having eight series of
shares, each of which has a different investment objective designed to meet
different investment needs. Four of the series are available to you. MassMutual
serves as the investment adviser to the MML Trust. MassMutual has entered into a
subadvisory agreement with David L. Babson and Company, Inc. ("Babson"), a
controlled subsidiary of MassMutual. Babson manages the investment of the assets
of the MML Equity Fund and the equity sector of the MML Blend Fund.      

MML Equity Fund. The MML Equity Fund seeks to achieve a superior rate of return
over time from both capital appreciation and current income and to preserve
capital by investing in equity securities.

MML Money Market Fund. The MML Money Market Fund seeks to maximize current
income, to preserve capital and to maintain liquidity by investing in money
market instruments.

MML Managed Bond Fund. The MML Managed Bond Fund seeks a high rate of return,
consistent with capital preservation, by investing primarily in investment
grade, publicly-traded, fixed income securities.

MML Blend Fund. The MML Blend Fund seeks a high total rate of return over time,
consistent with prudent investment risk and capital preservation, by investing
in equity, fixed income and money market securities.

- --------------------------------------------------------------------------------
There is no assurance that the funds will achieve their stated objective. The
fund prospectuses contain more detailed information about the funds. Current
copies of the fund prospectuses are attached to this prospectus. You should read
the information contained in the funds' prospectuses carefully before investing.
- --------------------------------------------------------------------------------

Contract Value 

Your contract value is your value in the separate account. Your value in the
separate account will vary depending on the investment performance of the funds
you choose. In order to keep track of your contract value, we use a unit of
measure called an accumulation unit. During the income phase of your contract we
call the unit an annuity unit.


Accumulation Units

Every business day we determine the value of an accumulation unit for each of
the funds. Changes in the accumulation unit value reflect the investment
performance of the funds as well as the deductions we make for our separate
account charges.

The value of an accumulation unit may go up or down from business day to
business day. The Statement of Additional Information contains more information
on the calculation of contract value.

When you make a purchase payment, we credit your contract with accumulation
units. We determine the number of accumulation units to credit by dividing the
amount of the purchase payment allocated to a fund by the value of one
accumulation unit for that fund. When you make a withdrawal, we deduct from your
contract accumulation units representing the withdrawal.

We calculate the value of an accumulation unit for each fund after the New York
Stock Exchange closes each business day. Any change in the accumulation unit
value will be reflected in your contract value.

Example:

On Monday we receive an additional purchase payment of $5,000 from you. You have
told us you want this to go to the MML Blend Fund. When the New York Stock
Exchange closes on that Monday, we determine that the value of an accumulation
unit for the MML Blend is $13.90. We then divide $5,000 by $13.90 and credit
your contract on Monday night with 359.71 accumulation units for the MML Blend
Fund.


Transfers

Transfers During the Accumulation Phase

You may transfer all or part of your contract value among the funds without
charge. You may not make transfers during the period 30 days before your
contract enters the income phase.

You can make transfers by telephone. If you want to use our automatic voice
response system, you must submit a written request to obtain a personal
identification number (PIN). We will use reasonable procedures to confirm that
instructions given to us by telephone are genuine. We may be liable for any
losses due to unauthorized or fraudulent instructions, if we fail to use such
procedures. We may tape record all telephone instructions. We do not offer the
telephone transfer service to contracts owned by custodians, guardians or
trustees.
    
Your transfer is effective on the business day we receive your request at our
Annuity Service Center. Our business day closes when the New York Stock Exchange
closes, usually 4:00 p.m. Eastern time. If we receive your transfer request
at our Annuity Service Center on a non-business day or after our business day
closes, your transfer request will be effective on the next business day.      

Transfers During the Income Phase

We do not permit transfers during the income phase.


Withdrawals

During the accumulation phase you may make either a partial or total withdrawal
of your contract value. The Internal Revenue Code imposes special rules in the
case of a TSA contract.

                                                                              11
<PAGE>
 
If you make a partial withdrawal, you must tell us from which investment
choice(s) you want the withdrawal taken. You must withdraw at least $100 or the
entire value in a fund, if less. If your request for a partial withdrawal will
reduce your contract value to less than $600, we will treat the request as a
full withdrawal of your contract value.

Full or partial withdrawals may be subject to a contingent deferred sales
charge.

When you make a total withdrawal you will receive the value of your contract:

 .    less any applicable contingent deferred sales charge;

 .    less any applicable premium tax;

 .    less any purchase payments we credited to your contract that have not
     cleared the bank, until they clear the bank; and

 .    less an administrative charge if you fully withdraw your contract value on
     a date other than the contract anniversary.

Your withdrawal is effective on the business day we receive your request at our
Annuity Service Center. If we receive your request at our Annuity Service Center
on a non-business day or after our business day closes, your withdrawal request
will be effective on the next business day. We will pay any withdrawal amount
within 7 days of our receipt of your fully completed written request at our
Annuity Service Center unless we are required to suspend or postpone withdrawal
payments.

You may receive your withdrawal amount in one lump sum or apply it to one of the
payment options offered.

- --------------------------------------------------------------------------------
Income taxes, tax penalties and certain restrictions may apply to any withdrawal
you make.

Expenses

There are charges and other expenses associated with the contracts that reduce
the return on your investment in the contract. These charges and expenses ate:


Insurance Charge

Each business day we deduct an insurance charge from the assets of the separate
account. We do this as part of our calculation of the value of the accumulation
units and the annuity units. This charge is equal, on an annual basis, to 1.25%
of the daily value of the assets invested in each fund, after fund expenses are
deducted. We refer to this charge as an asset charge. This charge is for:

 .    the mortality risk associated with the insurance benefits we provide,
     including our obligation to make annuity payments after the maturity date
     regardless of how long all annuitants live, the death benefits, and the
     guarantee of rates used to determine your annuity payments during the
     income phase; and

 .    the expense risk that the current administrative charge and the contingent
     deferred sales charge will be insufficient to cover the actual cost of
     administering the contracts.

If the asset charge is not sufficient to cover the actual costs, we will bear
the loss. However, we do expect to profit from this charge.


Administrative Charge

On each contract anniversary, we impose an administrative charge against each
contract to reimburse us for expenses relating to the issuance and maintenance
of the contract. The charge is $35. We may increase this charge, but it will not
exceed $50.

We make this deduction from your contract value in proportion to your value in
each fund.

Your first contract anniversary is one calendar year from the date we issued
your contract. 

We also deduct this charge between contract anniversary dates:

 .    if you fully withdraw your contract value;

 .    on the maturity date; or

 .    if the annuitant dies while the contract is in the accumulation phase, and
     the death benefit is the contract value.

We will not assess the administrative charge against any contract purchased with
proceeds from:

 .    a variable annuity contract issued by MassMutual which was subject to an
     initial sales charge;

 .    any fixed dollar life insurance or fixed dollar annuity contract issued by
     MassMutual where such proceeds were not subject to a surrender charge; or

 .    a variable annuity contract held under a MassMutual Agent Pension Plan;

if within six months of the purchase of a contract, you had purchased a new
contract and kept both contracts in force.

We have set the administrative charge so that we do not profit from this charge.


Contingent Deferred Sales Charge

We do not deduct a sales charge when we receive a purchase payment. However, we
may assess a contingent deferred sales charge if: 

 .    you withdraw all or part of your contract value, or

 .    you elect to receive fixed annuity payments on your contract maturity date,
     or

 .    you elect to receive a lump-sum payment on your contract maturity date.

We use this charge to cover certain expenses related to the sale of the
contract.

The amount of the contingent deferred sales charge depends on the following two
factors:

                                                                              13
<PAGE>
 
1.   The total amount of purchase payments you make, and

2.   The length of time between when you make the purchase payments and when you
     withdraw them, or when your contract reaches its maturity date.

The contingent deferred sales charge ranges from 11% to 0% on the value of the
accumulation units purchased with your first $3,000 of purchase payments. We
will assess a contingent deferred sales charge of 11% if you redeem accumulative
units in the same contract year you purchased them. This charge decreases 1%
each contract year from the date you made the purchase payments.

The contingent deferred sales charge ranges from 5% to 0% on the value of the
accumulation units purchased with your cumulative purchase payments between
$3,000 and $35,000. We will assess a contingent deferred sales charge of 5% if
you redeem accumulation units in the same contract year you purchased them. This
charge declines 1% each contract year from the date you made the purchase
payments.

We do not assess a contingent deferred sales charge on the value of the
accumulation units purchased with your cumulative purchase payments in excess of
$35,000.

We will redeem accumulation units with the lowest applicable contingent deferred
sales charge First.

The contingent deferred charge is illustrated in the following table:

The amount of the contingent deferred sales charge we deduct at any time, plus
contingent deferred sales charges we previously deducted, will not exceed 8.5%
of the total purchase payments you made to that time.

In addition to the free withdrawals described later in this section, we will not
impose a contingent deferred sales charge under the following circumstances: 

 .    Against purchase payments made by exchanging a previously issued MassMutual
     variable annuity contract which was subject to an initial sales charge;

 .    Against purchase payments made by exchanging any fixed dollar life
     insurance or fixed dollar annuity contract issued by MassMutual where such
     proceeds were not subject to a surrender charge;

 .    Against purchase payments made by exchanging a variable annuity contract
     held under the MassMutual Agent Pension Plan; or 

 .    Against a contract exchanged for a Flex Extra variable annuity contract
     issued by MassMutual.

Free Withdrawals

Beginning in the 5th contract year, we will not deduct a contingent deferred
sales charge if you redeem up to 10% of the number of accumulation units in each
fund as of the last day of the preceding contract year. You may not carry over
any unused portion of this 10% free withdrawal amount to any future contract
year.


Premium Taxes
    
Some states and other governmental entities charge premium taxes or similar
taxes. We are responsible for the payment of these taxes. We currently deduct
from any purchase payment any premium tax that is due when purchase payments are
made before allocating the payment to your investment choice. However, we will
deduct the premium taxes at the time of death, withdrawal of your total contract
value, or when annuity payments begin, if state law requires. We do not expect
to make a profit from this deduction. Premium taxes generally range from 0% to
3.5%, depending on the state.      


Transfer Fee

There is no charge for transfers during the accumulation phase. We do not allow
transfers during the income phase.


Income Taxes

We will deduct from the contract any income taxes that we incur because of the
operation of the separate account. At the present time, we are not making any
such deductions. We will deduct any withholding taxes required by law.


Fund Expenses

There are deductions from and expenses paid out of the assets of the various
funds, which are described in the attached fund prospectuses. We may enter into
certain arrangements under which we are reimbursed by the funds' advisors,
distributors and/or affiliates for the administrative services that we provide.

                                                                              15
<PAGE>
 
The Income Phase

If you want to receive regular income from your annuity, you can choose to
receive fixed or variable annuity payments under one of several annuity options.
You also may elect to receive your contract value in one sum. If you elect a
fixed annuity payment or a lump-sum payment, we may assess a contingent deferred
sales charge against your contract value on the maturity date.

You can choose the month and year in which those payments begin. We call that
date the maturity date.

We ask you to choose your maturity date when you purchase your contract. You can
defer your maturity date to any allowable date later than your current maturity
date provided we receive your written request at our Annuity Service Center at
least 90 days before the current maturity date. You can also elect to have an
earlier maturity date than the current date in effect, provided that we receive
the written request at least 31 days before the new maturity date you elected.

You may elect an annuity option at any time before the maturity date. If you do
not elect an annuity option by the maturity date, we will assume that you
selected a variable monthly annuity under a life income option with 120 payments
guaranteed.

Annuity payments must begin by the earlier of:

1.   the contract anniversary nearest to the annuitant' s 85th birthday, if you
     allocate your purchase payments to Separate Account 2;

2.   the contract anniversary nearest to the annuitant' s 75th birthday, if you
     allocate your purchase payments to Separate Account 1.

In order to avoid adverse tax consequences, you should begin to take
distributions at least equal to the minimum amount required by the IRS, no later
than the required beginning date. If your contract is an IRA, that date should
be the year you reach age 70 1/2. For qualified plans and TSAs, that date is the
later of your retirement or when you reach age 70 1/2.

At the maturity date, you have the same fund choices that you had during the
accumulation phase. If you elect variable annuity payments and do not tell us
otherwise, we will base your annuity payments on the investment allocations that
are in place on the maturity date.

After the maturity date, we will not assess a contingent deferred sales charge
if the annuitant withdraws up to the full amount of the then present value of
any remaining unpaid payments certain under the payment option. The beneficiary
may make these withdrawals if the annuitant has died. However, when you elect a
payment option, you may indicate that the annuitant does not have the right to
withdraw unpaid payments certain under the lifetime payment option or the joint
lifetime payment options.


Fixed Annuity Payments

If you choose Fixed payments, the payment amount will not vary. The payment
amount will depend upon the following 6 things:

 .    the value of your contract on the maturity date;

 .    the deduction of any applicable premium taxes; 

 .    the annuity option you select; 

 .    the age and sex of the annuitant (and joint annuitant if a joint payment
     option is elected);

 .    the deduction of any applicable contingent deferred sales charge; and

 .    the deduction of an administrative charge. 

16
<PAGE>
 
Variable Annuity Payments

If you choose variable payments, over time the payment amount will vary with the
investment performance of the funds. The first payment amount will depend on the
following 6 things:

 .    the value of your contract on the maturity date; 

 .    the deduction of any applicable premium taxes;

 .    the deduction of an administrative charge;

 .    the annuity option you select;

 .    the age and sex of the annuitant (and joint annuitant if a joint payment
     option is elected); and

 .    an assumed investment rate (AIR) of 4% per year.

Future variable payments will depend on the performance of the funds you
selected. If the actual performance exceeds the 4% assumed investment rate plus
the deductions for expenses, your annuity payments will increase. Similarly, if
the actual rate is less than 4% plus the amount of the deductions, your annuity
payments will decrease.


Annuity Unit Value

In order to keep track of the value of your variable annuity payment, we use a
unit of measure called an annuity unit We calculate the number or your annuity
units at the beginning of the income phase. During the income phase, the number
of annuity units will not change. However, the value of your annuity units will
change to reflect the investment performance of the funds you selected.

For a more detailed description of how the value of an annuity unit and the
amount of the variable annuity payments are calculated, see the Statement of
Additional Information.


Annuity Options

The following annuity options are available. After annuity payments begin, you
may not transfer among the funds. In addition, under most income options, you
may not change the annuity option, the frequency of annuity payments or make
withdrawals once your contract is in the income phase.

Fixed Income Payment Option. We will make each monthly payment for an agreed
fixed amount. Each monthly payment will be at least $10 for each $1,000 applied.
We will pay interest on the unpaid balance each month at a rate we determine.
This rate will not be less than 3% per year. Payments will continue until the
amount we hold runs out (Not available as a variable annuity payment.)

Fixed Time Payment Option. We will make equal monthly payments for any period
you select, up to 30 years. The amount of each payment depends on your contract
value at the maturity date, the period you select and the monthly payment rates
we use when your first payment is due. You may elect this option with either
fixed or variable payments.

Lifetime Payment Option. We will make fixed or variable annuity payments based
on the life of the annuitant. If you choose a variable annuity payment plan, the
payments are not guaranteed as to the amount, and may vary. If you elect this
option, annuity payments will be made either:

1.   without any guaranteed number of payments;

2.   with payments guaranteed for the amount applied; or

3.   with payments guaranteed for 5 or 10 years.

Interest Payment Option. We will hold any amount applied under this option. We
will pay any interest on the unpaid balance each month at a rate we determine.
This rate will not be less than 3% per year. (Not available as a variable
annuity payment.)

Joint Lifetime Payment Option. We will make fixed or variable payments based on
the lives of 2 named people. If a fixed income is elected, the payments are
equal. If a variable income is elected, the payments are not guaranteed as to
amount and may vary. 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 of this option are:

                                                                              17
<PAGE>
 
1.   Payments for two lives only. We guarantee no specific number of payments.
     Payments stop when both 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.

Joint Lifetime Payment Option With Reduced Payments. We will make Fixed or
variable monthly payments based on the lives of two annuitants. When one dies,
we will make reduced payments during the lifetime of the survivor. We will stop
payments once both annuitants have died. These reduced payments will be
two-thirds of what they would have been if both annuitants had continued to
live.

If your contract value is less than $2,000 on the maturity date, or if the
annuity option you elect produces an initial monthly payment of less than $20,
we reserve the right to pay you a lump sum less any applicable contingent
deferred sales charge, rather than a series of annuity payments.


Payments After Death of an Annuitant

Generally, if a payment option with a guaranteed number of payments is elected,
and the annuitant dies before we have completed the guaranteed number of
payments, we will pay in one sum the present value of any unpaid payments under
the option to the beneficiary. We will determine the present value as of the
business day we receive written notice of death at our Annuity Service Center.


Limitation on Payment Options

If you purchase a contract as a TSA or an IRA, the Internal Revenue Code imposes
restrictions on the types of payment options that you may elect.

18

Payments On Death


Death Of Annuitant During Accumulation Phase

If the annuitant dies during the accumulation phase, we will pay a death benefit
to the beneficiary. The death benefit will be the greater of:

1.   the total of all purchase payments, less any withdrawals and any applicable
     charges; or

2.   your contract value as of the business day we receive proof of death, less
     any applicable administrative charge. 

We will deduct the amount of any applicable premium taxes.

We may pay the death benefit in one sum within 7 days after we receive due proof
of death and all other required forms at our Annuity Service Center. With our
consent, you may have the death benefit paid under one of the available payment
options.

We will credit interest on the death benefit until we pay the death benefit in
one sum or apply it to a payment option, at the greater of:

 .    the interest rate we currently pay on amounts held in our general account
     under interest payment settlement options, or

 .    the rate earned by the Money Market Division, adjusted by the deduction of
     the asset charge.

We do not impose a contingent deferred sales charge on death benefit 
payments.

                                                                              19

Taxes


NOTE: We have prepared the following information on taxes as a general
discussion of the subject. It is not intended as tax advice to any individual.
You should consult your own tax adviser about your own circumstances. We have
included in the Statement of Additional Information an additional discussion
regarding taxes.


Annuity Contracts In General

Annuity contracts are a means of setting aside money for future needs - usually
retirement. Congress recognized how important saving for retirement was and
provided special rules in the Internal Revenue Code (Code) for annuities.

Simply stated, these rules provide that you will not be taxed on the earnings on
the money held in your annuity contract until you take the money out. This is
referred to as tax deferral. There are different rules as to how you are taxed
depending on how you take the money out and the type of contract - qualified or
non-qualified.

You, as the owner of a non-qualified annuity, will generally not be taxed on
increases in the value of your contract until a distribution occurs - either as
a withdrawal or as annuity payments. When you make a withdrawal, you are taxed
on the amount of the withdrawal that is earnings. For annuity payments,
different rules apply. A portion of each annuity payment is treated as a partial
return of your purchase payments and is not taxed. The remaining portion of the
annuity payment is treated as ordinary income. How the annuity payment is
divided between taxable and non-taxable portions depends upon the period over
which the annuity payments are expected to be made. Annuity payments received
after you have recovered all of your purchase payments are fully includible in
income.

When a non-qualified contract is owned by a non-natural person (e.g.,
corporation or certain other entities other than a trust holding the contract as
an agent for a natural person), the contract will generally not be treated as an
annuity for tax purposes.


Qualified And Non-Qualified Contracts

If you purchase the contract as an individual and not under any pension plan,
specially sponsored program or an individual retirement annuity, your contract
is referred to as a non-qualified contract.

If you purchase the contract under a pension plan, specially sponsored program,
or an individual retirement annuity, your contract is referred to as a qualified
contract. Examples of qualified plans are: Individual Retirement Annuities
(IRAs) and pension and profit-sharing plans, which include 401(k) plans and H.R.
10 Plans.


Withdrawals - Non-Qualified Contracts

If you make a withdrawal from your contract, the Code treats that withdrawal as
first coming from earnings and then from your purchase payments. Such withdrawn
earnings are includible in income.

The Code also provides that any amount received under an annuity contract that
is included in income may be subject to a penalty. The amount of the penalty is
equal to 10% of the amount that is includible in income. Some withdrawals will
be exempt from the penalty. They include any amounts:

1.   paid on or after you reach age 59 1/2;

2.   paid to your beneficiary after you die;

3.   paid if you become totally disabled (as that term is defined in the Code);

4.   paid in a series of substantially equal payments made annually (or more
     frequently) for life or a period not exceeding life expectancy;

5.   paid under an immediate annuity; or

20
<PAGE>
 
6.   which come from purchase payments made prior to August 14, 1982.


Withdrawals - Qualified Contracts

If you have no cost basis for your interest in a qualified contract, the full
amount of any distribution is taxable to you as ordinary income. If you do have
a cost basis for your interest, a portion of the distribution is taxable,
generally based on the ratio of your cost basis to your total contract value.
Special tax rules may be available for certain distributions from a qualified
contract.

Section 72(t) of the Code imposes a 10% penalty tax on the taxable portion of
any distribution from qualified retirement plans, including contracts issued and
qualified under Code Sections 401 (Pension and Profit-Sharing Plans), 408
(Individual Retirement Annuities - IRAs), and 408A (Roth IRAs). Exceptions from
the penalty tax are as follows:

 .    distributions made on or after you reach age 59 1/2;

 .    distributions made after your death or disability (as defined in Code
     Section 72(m)(7);

 .    after separation from service, distributions that are part of substantially
     equal periodic payments made not less frequently than annually for your
     life (or life expectancy) or the joint lives (or joint life expectancies)
     of you and your designated beneficiary (in applying this exception to
     distributions from IRAs, a separation from service is not required);

 .    distributions made after separation of service if you have reached age 55
     (not applicable to distributions from IRAs);

 .    distributions made to you up to the amount allowable as a deduction to you
     under Code Section 213 for amounts you paid during the taxable year for
     medical care;

 .    distributions made to an alternate payee pursuant to a qualified domestic
     relations order (not applicable to distributions from IRAs);

 .    distributions from an IRA for the purchase of medical insurance (as
     described in Code Section 213(d)(1)(D)) for you and your spouse and
     dependents if you received unemployment compensation for at least 12 weeks
     and have not been re-employed for at least 60 days);

 .    distributions from an IRA to the extent they do not exceed your qualified
     higher education expenses (as defined in Code Section 72(t)(7) for the
     taxable year; and

 .    distributions from an IRA which are qualified first-time home buyer
     distributions (as defined in Code Section 72(t)(8)).

Generally, distributions from a qualified plan must begin no later than April
1st of the calendar year following the later of (a) the year in which you attain
age 70 1/2 or (b) the calendar year in which you retire. The date set forth in
(b) does not apply to an IRA. Required distributions do not apply to a Roth IRA
during your lifetime. Required distributions must be over a period not exceeding
your life expectancy or the joint lives or joint life expectancies of you and
your designated beneficiary. If required minimum distributions are not made, a
50% penalty tax is imposed on the amount that should have been distributed.


Withdrawals - Tax-Sheltered Annuities

The Code limits the withdrawal of purchase payments made by owners through
salary reductions from certain Tax-Sheltered Annuities. Withdrawals of salary
reduction amounts and their earnings can only be made when an owner:

 .    reaches age 59 1/2;

 .    leaves his/her job;

 .    dies;

 .    becomes disabled, as that term is defined in the Code; or 

 .    in the case of hardship.

In the case of hardship, the owner can only withdraw his/her own purchase
payments made through salary reductions and not any earnings. Any contract value
as of December 31, 1988 is not subject to these restrictions. Additionally,
return of "excess contributions" or amounts paid to a spouse as a result of a
qualified domestic 

                                                                              21
<PAGE>
 
Withdrawals - Texas Optional 
Retirement Program

No withdrawals may be made in connection with a contract issued pursuant to the
Texas Optional Retirement Program for faculty members of Texas public
institutions of higher learning before you:

 .    terminate employment in all such institutions and repay employer
     contributions if termination occurs during the First twelve months of
     employment;

 .    retire;

 .    die; or

 .    attain age 70 1/2.

Other Information

Performance
                                        
We may advertise certain performance-related information. This information
reflects historical performance and is not intended to indicate or predict the
future performance.


Standardized Total Returns

We will show standardized average annual total returns for separate account
divisions that have been in existence for more than one year. These returns
assume you made a single $1,000 payment at the beginning of the period and
withdrew the entire amount at the end of the period. The return reflects a
deduction for the contingent deferred sales charge, the administrative charge
and all other separate account and contact level charges, except premium taxes,
if any.

If a division has been in existence for less than one year, we will show the
aggregate total return. This assumes you made a single $1,000 payment at the
beginning of the period and withdrew the entire amount at the end of the period.
The return reflects the change in unit value and a deduction of the contingent
deferred sales charge.


Nonstandard Total Returns

We will also show total returns based on historical performance of the divisions
and underlying funds. We may assume the contacts were in existence prior to
their inception date, August 18, 1982, which they were not. Total return
percentages included all fund level and separate account level charges. They do
not include a contingent deferred sales charge, administrative charge, or
premium taxes, if any. If these charges were included, returns would be less
than those shown.

Total Returns compare the value of an accumulation unit at the beginning of a
period with the value of an accumulation unit at the end of the period.

Average Annual Total Returns measure this performance over a period of time
greater than one year. Average annual total returns compare values over a given
period of time and express the percentage as an average annual rate.

Yield and Effective Yield

We may also show yield and effective yield for the MML Money Market Fund over a
seven-day period, which we will then "annualize". This means that when we
calculate yield, we assume that the amount of money the investment earns for the
week is earned each week over a 52-week period. We show this as a percentage of
the investment. We calculate the "effective yield" similarly, but when we
annualize the amount, we assume the income earned is reinvested. Therefore the
effective yield is slightly higher than the yield because of the compounding
effect.


Year 2000
                                        
Like other businesses and governments around the world, we could be adversely
affected if the computer systems used by us and those with which we do business
do not properly recognize the year 2000. This is commonly known as the "Year
2000 issue".

In 1996, we began an enterprise-wide process of identifying, evaluating and
implementing changes to computer systems and applications software to address
the Year 2000 issue on our own behalf and on behalf of certain subsidiaries. We
are addressing the Year 2000 issue internally with modifications to existing
programs and conversions to new programs. We are also seeking assurances from
vendors, customers, service providers, governments and others with which we
conduct business, to determine their year 2000 readiness.

The costs related to the Year 2000 issue are currently being expensed, and when
measured against net gain from operations, are not material to us.


                                                                              23
<PAGE>
 
Distributors
                                        
MML Investors Services, Inc. (MMLISI), a wholly-owned subsidiary of MassMutual,
acted as the principal underwriter for the contracts. The contracts are no
longer offered for sale to the public. However, you may continue to make
purchase payments to your contract. MMLISI is the current broker-dealer for the
existing contracts. MMLISI's address is 1414 Main Street, Springfield,
Massachusetts 01144-1013.

Assignment
                                        
The contract cannot be sold, discounted, assigned or pledged as a collateral for
a loan, security for the performance of any other obligation, or any other
purpose to anyone other than us.

Voting Rights
                                        
We are the legal owner of the fund shares. However, when a fund solicits proxies
in conjunction with a vote of shareholders, it is required to obtain from you
and other owners, instructions as to how to vote those shares. When we receive
those instructions, we will vote all of the shares, for which we have not
received voting instructions, in proportion to those instructions. This will
also include any shares that we own on our own behalf If we determine that we
are no longer required to comply with the above, we will vote the shares in our
own right.

During the accumulation phase of your contract and while the annuitant is
living, we determine the number of shares you may vote by dividing your contract
value in each fund, if any, by $100. Fractional shares are counted. During the
income phase or after the annuitant dies, we determine the number of shares you
may vote based on our liability for future variable monthly annuity payments.

Reservation Of Rights

We reserve the right to:

 .    Substitute another fund for one of the funds you have selected;

 .    Add separate account divisions;

 .    Change the name of a separate account; and

 .    Split or consolidate the number of accumulation units or annuity units for
     any separate account division and correspondingly decrease or increase the
     accumulation or annuity unit values for any division.

If we exercise any of these rights, we will receive prior approval from the
Securities and Exchange Commission, when necessary. We will also give you notice
of our intent to exercise any of these rights.

Suspension Of Payments Or Transfers

We may be required to suspend or postpone payments for withdrawals or transfers
from the funds for any period when:

 .    the New York Stock Exchange is closed (other than customary weekend and
     holiday closings) or trading on the New York Stock Exchange is restricted;
     or

 .    an emergency exists as a result of which disposal of shares of the funds is
     not reasonably practicable or we cannot reasonably value the shares of the
     fund; or

 .    during any other period when the Securities and Exchange Commission, by
     order, so permits for your protection.


Legal Proceedings

We are currently not involved in any legal proceedings that might adversely
impact the contracts.

                              GENERAL INFORMATION


                                   MassMutual
                                   ----------
    
Massachusetts Mutual Life Insurance Company ("MassMutual") is a mutual life
insurance company specially chartered by the Commonwealth of Massachusetts on
May 14, 1851. It is currently licensed to transact life (including variable
life), accident, and health insurance business in all states, the District of
Columbia, Puerto Rico and certain provinces of Canada. MassMutual had
consolidated statutory assets in excess of $67 billion and estimated total
assets under management of $176.8 billion as of December 31, 1998. Its Home
Office is located in Springfield, Massachusetts.     



                             The Separate Accounts
                             ---------------------

Massachusetts Mutual Variable Annuity Separate Account 1 ("Separate Account 1")
was established as a separate investment account of MassMutual on April 8, 1981
in accordance with the provisions of Chapter 175 of the Massachusetts General
Laws. Massachusetts Mutual Variable Annuity Separate Account 2 ("Separate
Account 2") was established as a separate investment account of MassMutual on
October 14, 1981 in accordance with the provisions of Chapter 175 of the
Massachusetts General Laws.

Each 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 Accounts or of MassMutual. Under Massachusetts law, however, both
MassMutual and each Separate Account are subject to regulation by the Division
of Insurance of the Commonwealth of Massachusetts.

Although the assets of each Separate Account are assets of MassMutual, assets of
each Separate Account equal to the reserves and other Flex-Annuity Contract
liabilities which depend on the investment performance of the Separate Account
are not chargeable with liabilities arising out of any other business MassMutual
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 MassMutual. All obligations arising under the
Flex-Annuity contracts (the "contracts"), however, are general corporate
obligations of MassMutual.



                             ASSIGNMENT OF CONTRACT
                                        
MassMutual 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 the original or a true copy thereof is received at its Home
Office. MassMutual assumes no responsibility for the validity of any assignment.

While the contracts are generally assignable, all non-tax qualified (Separate
Account 2) contracts must carry a non-transferability endorsement which
precludes their assignment. For qualified (Separate Account 1) 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 MassMutual at its Home Office. 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,
     MassMutual reserves the right to pay to 

                                       2
<PAGE>
 
     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 prior to the maturity date, MassMutual
     will pay to the assignee in one sum, to the extent that he is entitled, the
     greater of (a) the total of all purchase payments, less the net amount of
     all partial redemptions, and (b) the accumulated value of the contract less
     the administrative charge, and any balance of such value will be paid to
     the beneficiary in one sum or applied under one or more of the payment
     options elected;

     (3) Contracts used in connection with a tax-qualified retirement plan must
     be endorsed to provide that they may not be sold, assigned or pledged for
     any purpose unless they are owned by the trustee of a trust described in
     Section 401(a) or by the administrator of an annuity plan described under
     Section 403(a) of the Code;

     (4) 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;

     (5) 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 MassMutual, except to a former spouse of the annuitant in
     accordance with the terms of a divorce decree of other written instrument
     incident to a divorce.

Redemptions of TSAs may be restricted as required by Section 403(b)(11) of the
Internal Revenue Code (see, "Withdrawals - Tax-Sheltered Annuities" in the
prospectus for details). In restricting any such redemption, MassMutual relies
on the relief from sections 22(c), 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 represents that it complies with the
provisions of paragraphs (1)-(4) as set forth in the No Action Letter.     

                        DISTRIBUTION AND ADMINISTRATION
                                        
Under a Servicing Agreement between MML Investors Services, Inc. ("MMLISI"), a
wholly-owned subsidiary of MassMutual, and the Separate Accounts, MMLISI agreed
to act as principal underwriter for each Separate Account and each Separate
Account agreed that MMLISI would be its exclusive principal underwriter.
    
Under the Servicing Agreement, MMLISI may receive compensation for its
activities as principal underwriter. In 1998 and 1997 there was no such
compensation. Commissions will be paid through MMLISI to agents for selling the
contracts. During 1998 and 1997, commission payments amounted to $234,373 and
$337,411, respectively.     

Under Administration Agreements, MassMutual has agreed to provide, or provide
for, and assume: (1) all services and expenses required for the administration
of those contracts which depend in whole or in part on the investment
performance of the Separate Accounts; and (2) all services and expenses required
for the administration of the Separate Accounts other than the services and
expenses referred to in (1). MassMutual also has agreed to provide, or provide
for, and assume all services and expenses required for the Separate Accounts'
management-related services. MassMutual receives no compensation for such
services apart from the various charges against the contract described in the
Prospectus.

These Servicing and Administrative Agreements may be terminated by the parties
without the payment of any penalty upon thirty days' written notice. The
agreements immediately terminate in the event of their assignment (within the
meaning of the Investment Company Act of 1940). The agreements may be amended at
any time by the mutual consent of the parties. The contract owner will not
receive notice with respect of changes in the agreement.

As of March 31, 1988, the contracts are no longer offered for sale. Purchase
payments will, however, continue to be accepted under the contracts.

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 each
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 will vary from Valuation Date to Valuation Date. The initial
Accumulation Unit Value for each Division was set at $1 .00000000. 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.

                  --------------------------------------------
                             of a Separate Account
                             ---------------------
                                        
You may allocate purchase payments among the four Divisions of the Separate
Account. At the end of each Valuation Period MassMutual will apply your purchase
payment (after deducting any applicable premium taxes) 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 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 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 on the date a purchase payment is received in good
order by MassMutual in the mail or by wire transfer at MassMutual's Annuity
Service Center or a designated bank lock box. 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 as of the next Valuation Time following the date
the payment is received. If a purchase payment is not applied to purchase
Accumulation Units within five business days after receipt at MassMutual's
Annuity Service Center (due to incomplete or ambiguous instructions, for
example) the payment will be refunded unless specific consent to retain the
payment for a longer period is obtained from the prospective purchaser.

                             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 1.00000000, decreased by the applicable Asset Charge.
The Net Investment Factor may be greater than or less than 1.00000000.

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

The Gross Investment Rate for each Division of a 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 each Division are 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 each Separate Account is to take dividends and capital gain
distributions on shares of the Funds held by each Separate Account in additional
shares and not in cash.

                                The Income Phase     
                                ----------------
    
When your contract approaches its maturity date, you may choose to have the
contract value provide you at maturity with either fixed annuity payments
(referred to as the "Fixed Income Option" in your contract), variable monthly
annuity payments (referred to as the "Variable Income Option" in your contract),
or a combination of the two. You also may elect to receive the contract value in
one lump sum. If you elect a fixed annuity or a lump sum payment, a contingent
deferred sales charge (as described in the Prospectus) may be deducted from the
accumulated value of your contract at maturity. If, however, you elect a
variable monthly annuity, no contingent deferred sales charge will be deducted
from the accumulated value of your contract. Variable monthly annuity payments
may be received under several different payment options. If you have made no
election within a reasonable time after the maturity date, the contract will
provide you with the automatic payment of a variable monthly annuity under a
life income option with payments guaranteed for 10 years.     


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

                            Variable Monthly Annuity
                            ------------------------
                                        
If you select a variable monthly annuity, 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 joint and survivor payment option with reduced survivor
income is elected. Variable monthly annuity 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 attributable to each
Division of the contract 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 annuity payment. Such value is then multiplied by the
purchase rate (as defined below) to determine the amount of the first variable
monthly annuity payment attributable to each Division. Finally, the amount of
the first variable monthly annuity 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 annuity 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 $1,000 of Accumulated Value at maturity date applied to
that Division. The purchase rates which will be applied will be those specified
in the contract or those in use by MassMutual when the first variable monthly
annuity payment is due, whichever provides the higher income. The purchase rate
will differ according to the payment option which you elect and 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
                                                        -----------------

                            Assumed Investment Rates
                            ------------------------
    
The Assumed Investment Rate for each 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 annuity payments will vary from month to month.
If the actual net investment performance for a Separate Account Division for the
period between the date any Variable Monthly Annuity payment is determined and
the date the next variable monthly annuity 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. The initial Annuity Unit Value
for each Division was set at $1.00000000. 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 1.00000000 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.

               -------------------------------------------------
                                        
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 .00003425 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 $1.13500000 and $1.06700000, 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 .00039200 ($11,760
divided by $30,000,000). The Net Investment Factor would be 1.00035775
(.00039200 plus 1.00000000 minus .00003425). The new Accumulation Unit Value
would be $1.13540605 ($1.13500000 x 1.00035775). At an effective annual rate of
4%, the rate of interest for one day is .00010746, and the new Annuity Unit
Value would be $l.06726703 ($1.06700000 x 1.00035775 divided by 1.00010746).

The above computations may be illustrated by the following hypothetical example:
Assume that 35,000 Accumulation Units in a Division of a 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
annuity payment was $1.35000000; and that the Annuity Unit Value of such
Division on the payment calculation date for the first variable monthly annuity
payment was $1.20000000 and for the second Variable Monthly Annuity payment was
$1.20050000.

The first variable monthly annuity payment would be $266.96 (35,000 x 1.35000000
x .00565). The number of Annuity Units of such Division credited would be
222.467 ($266.96 divided by $1.20000000). The amount of the second Variable
Monthly Annuity payment would be $267.07 (222.467 x $l.20050000). 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 annuity payment would be equal to the sum thereof.

                      Standardized Average Annual Total Return
                      ----------------------------------------

MassMutual will show standardized average annual total returns for each Separate
Account Division that has been in existence for more than one year. These
returns assume you made a single $1,000 payment at the beginning of the period
and withdrew the entire amount at the end of the period. The return reflects a
deduction for the contingent deferred sales charge, and all other fund, Separate
Account and contract level charges, except premium taxes, if any.

If a Separate Account Division has been in existence for less than one year,
MassMutual will show the aggregate total return. This assumes you made a single
$1,000 payment at the beginning of the period and withdrew the entire amount at
the end of the period. The return reflects the change in unit value and a
deduction of the contingent deferred sales charge.

The following tables show the standardized average annual total return for the
Divisions for the period ended December 31, 1998.

                           --------------------------
                                        
MassMutual will also show total returns based on historical performance of the
Divisions and underlying funds. MassMutual may assume the contracts were in
existence prior to their inception date (August 18, 1982), which they were not.
Total return percentages include all fund level and separate account level
charges. They do not include a contingent deferred sales charge, annual
administrative charge, or premium taxes, if any. If these charges were included,
returns would be less than those shown.

Total Returns compare the value of an accumulation unit at the beginning of a
period with the value of an accumulation unit at the end of the period.

Average Annual Total Returns measure this performance over a period of time
greater than one year. Average annual total returns compare values over a given
period of time and express the percentage as an average annual rate.

The performance figures discussed below, are calculated on the basis of the
historical performance of the funds, and may assume the contracts were in
existence prior to their inception date (August 18, 1982) which they were not.
Beginning on the contract inception date (August 18, 1982), actual accumulation
unit values are used for the calculations.

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, a nationally recognized independent
reporting service or similar service that rank mutual funds and other investment
companies by overall performance, investment objectives and assets; (b) compared
to indices; (c) tracked by other ratings services, companies, publications or
persons who rank separate accounts or other investment products on overall
performance or other criteria; and (d) 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.

MassMutual may also show yield and effective yield for the Money Market Division
over a seven-day period, which MassMutual then "annualizes". This means that
when MassMutual calculates yield, it assumes that the amount of money the
investment earns for the week is earned each week over a 52-week period.
MassMutual shows this as a percentage of the investment. MassMutual calculates
the "effective yield" similarly but when it annualizes the amount, MassMutual
assumes the income earned is re-invested. Therefore, the effective yield is
slightly higher than the yield because of the compounding effect.

These figures reflect a deduction for all Fund, Separate Account and contract
level charges assuming the contract remains inforce. The figures do not reflect
the contingent deferred sales charge or premium tax deductions (if any), which
if included would reduce the percentages reported.

The 7-day yield and effective yield for the Money Market Division for the period
ended December 31, 1998 are as follows:

Before Annual Administrative Charge Deduction 
7-Day Yield:
- ----------- 

Separate Account 1

                              FEDERAL TAX MATTERS
                                        

                                    General
                                        
Note: The following description is based upon MassMutual's understanding of
current federal income tax law applicable to annuities in general. MassMutual
cannot predict the probability that any changes in such laws will be made.
Purchasers are cautioned to seek competent tax advice regarding the possibility
of such changes. MassMutual does not guarantee the tax status of the contracts.
Purchasers bear the complete risk that the contracts may not be treated as
"annuity contracts" under federal income tax laws. It should be further
understood that the following discussion is not exhaustive and that special
rules not described herein may be applicable in certain situations. Moreover, no
attempt has been made to consider any applicable state or other tax laws.

Section 72 of the Code governs taxation of annuities in general. An owner is
generally not taxed on increases in the value of a contract until distribution
occurs, either in the form of a lump sum payment or as annuity payments under
the annuity option selected. For a lump sum payment received as a total
withdrawal (total surrender), the recipient is taxed on the portion of the
payment that exceeds the cost basis of the contract. For non-qualified
contracts, this cost basis is generally the purchase payments, while for
qualified contracts there may be no cost basis. The taxable portion of the lump
sum payment is taxed at ordinary income tax rates.

For annuity payments, a portion of each payment in excess of an exclusion amount
is includible in taxable income. The exclusion amount for payments based on a
fixed annuity option is determined by multiplying the payment by the ratio that
the cost basis of the contract (adjusted for any period or refund feature) bears
to the expected return under the contract. The exclusion amount for payments
based on a variable annuity option is determined by dividing the cost basis of
the contract (adjusted for any period certain or refund guarantee) by the number
of years over which the annuity is expected to be paid. Payments received after
the investment in the contract has been recovered (i.e. when the total of the
excludable amount equals the investment in the contract) are fully taxable. The
taxable portion is taxed at ordinary income tax rates. For certain types of
qualified plans there may be no cost basis in the contract within the meaning of
Section 72 of the Code. Owners, annuitants and beneficiaries under the contracts
should seek competent financial advice about the tax consequences of any
distributions.

MassMutual is taxed as a life insurance company under the Code. For federal
income tax purposes, the separate account is not a separate entity from
MassMutual, and its operations form a part of MassMutual.


                                Diversification

Section 817(h) of the Code imposes certain diversification standards on the
underlying assets of variable annuity contracts. The Code provides that a
variable annuity contract will not be treated as an annuity contract for any
period (and any subsequent period) for which the investments are not, in
accordance with regulations prescribed by the United States Treasury Department
("Treasury Department"), adequately diversified. Disqualification of the
contract as an annuity contract would result in the imposition of federal income
tax to the Owner with respect to earnings allocable to the contract prior to the
receipt of payments under the contract. The Code contains a safe harbor
provision which provides that annuity contracts such as the contract meet the
diversification requirements if; as of the end of each quarter, the underlying
assets meet the diversification standards for a regulated investment company and
no more than fifty-five percent (55%) of the total assets consist of cash, cash
items, U.S. Government securities and securities of other regulated investment
companies.

On March 2, 1989, the Treasury Department issued Regulations (Treas. Reg. 
1.817-5), which established diversification requirements for the investment
portfolios underlying variable contracts such as the contract. The regulations
amplify the diversification requirements for variable contracts set forth in the
Code and provide an alternative to the safe harbor provision described above.
Under the regulations, an investment portfolio will be deemed     

                                       11
<PAGE>
 
    
adequately diversified if: (1) no more than 55% of the value of the total assets
of the portfolio is represented by any one investment; (2) no more than 70% of
the value of the total assets of the portfolio is represented by any two
investments; (3) no more than 80% of the value of the total assets of the
portfolio is represented by any three investments; and (4) no more than 90% of
the value of the total assets of the portfolio is represented by any four
investments.

The Code provides that, for purposes of determining whether or not the
diversification standards imposed on the underlying assets of variable contracts
by Section 817(h) of the Code have been met, "each United States government
agency or instrumentality shall be treated as a separate issuer."

MassMutual intends that all investment portfolios underlying the contracts will
be managed in such a manner as to comply with these diversification
requirements.

The Treasury Department has indicated that the diversification regulations do
not provide guidance regarding the circumstances in which owner control of the
investments of the separate account will cause the owner to be treated as the
owner of the assets of the separate account, thereby resulting in the loss of
favorable tax treatment for the contract. At this time it cannot be determined
whether additional guidance will be provided and what standards may be contained
in such guidance.

The amount of owner control which may be exercised under the contract is
different in some respects from the situations addressed in published rulings
issued by the Internal Revenue Service in which it was held that the policy
owner was not the owner of the assets of the separate account. It is unknown
whether these differences, such as the owner's ability to transfer among
investment choices or the number and type of investment choices available, would
cause the owner to be considered as the owner of the assets of the separate
account resulting in the imposition of federal income tax to the owner with
respect to earnings allocable to the contract prior to receipt of payments under
the contract.

In the event any forthcoming guidance or ruling is considered to set forth a new
position, such guidance or ruling will generally be applied only prospectively.
However, if such ruling or guidance was not considered to set forth a new
position, it may be applied retroactively resulting in the owner being
retroactively determined to be the owner of the assets of the separate account.

Due to the uncertainty in this area, MassMutual reserves the right to modify the
contract in an attempt to maintain favorable tax treatment.


                               Multiple Contracts

The Code provides that multiple non-qualified annuity contracts which are issued
within a calendar year to the same contract owner by one company or its
affiliates are treated as one annuity contract for purposes of determining the
tax consequences of any distribution. Such treatment may result in adverse tax
consequences including more rapid taxation of the distributed amounts from such
combination of contracts. Owners should consult a tax adviser prior to
purchasing more than one non-qualified annuity contract in any calendar year.

                     Contracts Owned by Other than Natural Persons

Under Section 72(u) of the Code, the investment earnings on premiums for the
contracts will be taxed currently to the owner if the owner is a non-natural
person, e.g., a corporation or certain other entities. Such contracts generally
will not be treated as annuities for federal income tax purposes. However, this
treatment is not applied to a contract held by a trust or other entity as an
agent for a natural person nor to contracts held by qualified plans. Purchasers
should consult their own tax counsel or other tax adviser before purchasing a
contract to be owned by a non-natural person.     

                                       12
<PAGE>
 
    
                         Tax Treatment of Assignments

An assignment or pledge of a contract may be a taxable event. Owners should
therefore consult competent tax advisers should they wish to assign or pledge
their contracts.

                            Income Tax Withholding

All distributions or the portion thereof which is includible in the gross income
of the owner are subject to federal income tax withholding. Generally, amounts
are withheld from periodic payments at the same rate as wages and at the rate of
10% from non-periodic payments. However, the owner, in most cases, may elect not
to have taxes withheld or to have withholding done at a different rate.

Effective January 1, 1993, certain distributions from retirement plans qualified
under Section 401 of the Code, which are not directly rolled over to another
eligible retirement plan or individual retirement account or individual
retirement annuity, are subject to a mandatory 20% withholding for federal
income tax. The 20% withholding requirement generally does not apply to: a) a
series of substantially equal payments made at least annually for the life or
life expectancy of the participant or joint and last survivor expectancy of the
participant and a designated beneficiary or for a specified period of 10 years
or more; or b) distributions which are required minimum distributions; or c) the
portion of the distributions not includible in gross income (i.e. returns of
after-tax contributions). The 20% withholding requirement also does not apply to
hardship distributions from a 401(k) plan made after December 31, 1998.
Participants should consult their own tax counsel or other tax adviser regarding
withholding requirements.

             Tax Treatment of Withdrawals - Non-Qualified Contracts
                                        
Section 72 of the Code governs treatment of distributions from annuity
contracts. It provides that if the contract value exceeds the aggregate purchase
payments made, any amount withdrawn will be treated as coming first from the
earnings and then, only after the income portion is exhausted, as coming from
the principal. Withdrawn earnings are includible in gross income. It further
provides that a ten percent (10%) penalty will apply to the income portion of
any premature distribution. However, the penalty is not imposed on amounts
received: (a) after the taxpayer reaches age 59 1/2; (b) after the death of the
owner; (c) if the taxpayer is totally disabled (for this purpose disability is
as defined in Section 72(m)(7) of the Code); (d) in a series of substantially
equal periodic payments made not less frequently than annually for the life (or
life expectancy) of the taxpayer or for the joint lives (or joint life
expectancies) of the taxpayer and his or her beneficiary; (e) under an immediate
annuity; or (f) which are allocable to purchase payments made prior to August
14, 1982.

With respect to (d) above, if the series of substantially equal periodic
payments is modified before the later of your attaining age 59 1/2 or 5 years
from the date of the first periodic payment, then the tax for the year of the
modification is increased by an amount equal to the tax which would have been
imposed (the 10% tax penalty), but for the exception, plus interest for the tax
years in which the exception was used.

The above information does not apply to qualified contracts. However, separate
tax withdrawal penalties and restrictions may apply to such qualified contracts.
(See "Tax Treatment of Withdrawals - Qualified Contracts" below.)

                                Qualified Plans
                                        
The contracts offered herein are designed to be suitable for use under various
types of qualified plans. Taxation of participants in each qualified plan varies
with the type of plan and terms and conditions of each specific plan. Owners,
annuitants and beneficiaries are cautioned that benefits under a qualified plan
may be subject to the terms and conditions of the plan regardless of the terms
and conditions of the contracts issued pursuant to the plan. Some retirement
plans are subject to distribution and other requirements that are not
incorporated into MassMutual's administrative procedures. Owners, participants
and beneficiaries are responsible for determining that contributions,
distributions and other transactions with respect to the contracts comply with
applicable law. Following are general     

                                       13

descriptions of the types of qualified plans with which the contracts may be
used. Such descriptions are not exhaustive and are for general informational
purposes only. The tax rules regarding qualified plans are very complex and will
have differing applications depending on individual facts and circumstances.
Each purchaser should obtain competent tax advice prior to purchasing a contract
issued under a qualified plan.

Contracts issued pursuant to qualified plans include special provisions
restricting contract provisions that may otherwise be available as described
herein. Generally, contracts issued pursuant to qualified plans are not
transferable except upon surrender or annuitization. Various penalty and excise
taxes may apply to contributions or distributions made in violation of
applicable limitations. Furthermore, certain withdrawal penalties and
restrictions may apply to surrenders from qualified contracts. (See "Tax
Treatment of Withdrawals - Qualified Contracts" below.)

On July 6, 1983, the Supreme Court decided in Arizona Governing Committee v.
                                           ---------------------------------

compensation plan could not, under Title VII of the Civil Rights Act of 1964,
vary between men and women. The contracts sold by MassMutual in connection with
qualified plans will utilize annuity tables which do not differentiate on the
basis of sex. Such annuity tables will also be available for use in connection
with certain non-qualified deferred compensation plans.

a.   Tax Sheltered Annuities

Section 403(b) of the Code permits the purchase of "tax sheltered annuities" by
public schools and certain charitable, educational and scientific organizations
described in Section 50l(c)(3) of the Code. These qualifying employers may make
contributions to the contracts for the benefit of their employees. Such
contributions are not includible in the gross income of the employees until the
employees receive distributions from the contracts. The amount of contributions
to the tax sheltered annuity is limited to certain maximums imposed by the Code.
Furthermore, the Code sets forth additional restrictions governing such items as
transferability, distributions, nondiscrimination and withdrawals. (See "Tax
Treatment of Withdrawals - Qualified Contracts" and "Tax Sheltered Annuities -
Withdrawal Limitations" below.) Employee loans are not allowable under the
contracts. Any employee should obtain competent tax advice as to the tax
treatment and suitability of such an investment.

b.   H.R. 10 Plans

Section 401 of the Code permits self-employed individuals to establish qualified
plans for themselves and their employees, commonly referred to as "H.R. 10" or
"Keogh" plans. Contributions made to the plan for the benefit of the employees
will not be included in the gross income of the employees until distributed from
the Plan. The tax consequences to participants may vary depending upon the
particular plan design. However, the Code places limitations and restrictions on
all plans including on such items as: amount of allowable contributions; form,
manner and timing of distributions; transferability of benefits; vesting and
nonforfeitability of interests; nondiscrimination in eligibility and
participation; and the tax treatment of distributions, withdrawals and
surrenders. (See "Tax Treatment of Withdrawals - Qualified Contracts" below.)
Purchasers of contracts for use with an H.R. 10 Plan should obtain competent tax
advice as to the tax treatment and suitability of such an investment.

c.   Individual Retirement Annuities

Section 408(b) of the Code permits eligible individuals to contribute to an
individual retirement program known as an "Individual Retirement Annuity"
("IRA"). Under applicable limitations, certain amounts may be contributed to an
IRA which will be deductible from the individual's gross income. These IRAs are
subject to limitations on eligibility, contributions, transferability and
distributions. (See "Tax Treatment of Withdrawals - Qualified Contracts" below.)
Under certain conditions, distributions from other IRAs and other Qualified
Plans may be rolled over or transferred on a tax-deferred basis into an IRA.
Sales of contracts for use with IRAs are subject to special requirements imposed
by the Code, including the requirement that certain informational disclosure be
given to persons desiring to establish an IRA. Purchasers of contracts to be
qualified as Individual Retirement Annuities should obtain competent tax advice
as to the tax treatment and suitability of such an investment.     

                                       14
<PAGE>
 
    
     Roth IRAs

Section 408A of the Code provides that beginning in 1998, individuals may
purchase a new type of non-deductible IRA, known as a Roth IRA. Purchase
payments for a Roth IRA are limited to a maximum of $2,000 per year. Lower
maximum limitations apply to individuals with adjusted gross incomes between
$95,000 and $110,000 in the case of single taxpayers, between $150,000 and
$160,000 in the case of married taxpayers filing joint returns, and between $0
and $10,000 in the case of married taxpayers filing separately. An overall
$2,000 annual limitation continues to apply to all of a taxpayer's IRA
contributions, including Roth IRA and non-Roth IRAs.

Qualified distributions from Roth IRAs are free from federal income tax. A
qualified distribution requires that an individual has held the Roth IRA for at
least five years and, in addition, that the distribution is made either after
the individual reaches age 59 1/2, on the individual's death or disability, or
as a qualified first-time home purchase, subject to a $10,000 lifetime maximum,
for the individual, a spouse, child, grandchild, or ancestor. Any distribution
which is not a qualified distribution is taxable to the extent of earnings in
the distribution. Distributions are treated as made from contributions first and
therefore no distributions are taxable until distributions exceed the amount of
contributions to the Roth IRA. The 10% penalty tax and the regular IRA
exceptions to the 10% penalty tax apply to taxable distributions from a Roth
IRA.

Amounts may be rolled over from one Roth IRA to another Roth IRA. Furthermore,
an individual may make a rollover contribution from a non-Roth IRA to a Roth
IRA, unless the individual has adjusted gross income over $100,000 or the
individual is a married taxpayer filing a separate return. The individual must
pay tax on any portion of the IRA being rolled over that represents income or a
previously deductible IRA contribution. However, for rollovers in 1998, the
individual may pay that tax ratably over the four taxable year period beginning
with tax year 1998.

Purchasers of contracts to be qualified as a Roth IRA should obtain competent
tax advice as to the tax treatment and suitability of such an investment.

d.   Corporate Pension and Profit-Sharing Plans

Sections 401(a) and 401(k) of the Code permit corporate employers to establish
various types of retirement plans for employees. These retirement plans may
permit the purchase of the contracts to provide benefits under the plan.
Contributions to the plan for the benefit of employees will not be includible in
the gross income of the employees until distributed from the plan. The tax
consequences to participants may vary depending upon the particular plan design.
However, the Code places limitations and restrictions on all Plans including on
such items as: amount of allowable contributions; form, manner and timing of
distributions; transferability of benefits; vesting and nonforfeitability of
interests; nondiscrimination in eligibility and participation; and the tax
treatment of distributions, withdrawals and surrenders. (See "Tax Treatment of
Withdrawals - Qualified Contracts" below.) Purchasers of contracts for use with
Corporate Pension or Profit Sharing Plans should obtain competent tax advice as
to the tax treatment and suitability of such an investment.

               Tax Treatment of Withdrawals - Qualified Contracts
                                        
In the case of a withdrawal under a qualified contract, a ratable portion of the
amount received is taxable, generally based on the ratio of the individual's
cost basis to the individual's total accrued benefit under the retirement plan.
Special tax rules may be available for certain distributions from a qualified
contract. Section 72(t) of the Code imposes a 10% penalty tax on the taxable
portion of any distribution from qualified retirement plans, including contracts
issued and qualified under Code Sections 401 (H.R. 10 and Corporate Pension and
Profit-Sharing Plans), 403(b) (Tax-Sheltered Annuities), and 408 (Individual
Retirement Annuities) and 408A (Roth IRAs). To the extent amounts are not
includible in gross income because they have been rolled over to an IRA or to
another eligible qualified plan, no tax penalty will be imposed. The tax penalty
will not apply to the following distributions: (a) if distribution is made on or
after the date on which the owner or annuitant (as applicable) reaches age 
59 1/2; (b) distributions following the death or     

                                       15
<PAGE>
 
    
disability of the owner or annuitant (as applicable) (for this purpose
disability is as defined in Section 72(m) (7) of the Code); (c) after separation
from service, distributions that are part of substantially equal periodic
payments made not less frequently than annually for the life (or life
expectancy) of the owner or annuitant (as applicable) or the joint lives (or
joint life expectancies) of such owner or annuitant (as applicable) and his or
her designated beneficiary; (d) distributions to an owner or annuitant (as
applicable) who has separated from service after he has attained age 55; (e)
distributions made to the owner or annuitant (as applicable) to the extent such
distributions do not exceed the amount allowable as a deduction under Code
Section 213 to the owner or annuitant (as applicable) for amounts paid during
the taxable year for medical care; (f) distributions made to an alternate payee
pursuant to a qualified domestic relations order; (g) distributions from an
Individual Retirement Annuity for the purchase of medical insurance (as
described in Section 213(d)( 1)(D) of the Code) for the owner or annuitant (as
applicable) and his or her spouse and dependents if the owner or annuitant (as
applicable) has received unemployment compensation for at least 12 weeks (this
exception will no longer apply after the owner or annuitant (as applicable) has
been re-employed for at least 60 days); (h) distributions from an Individual
Retirement Annuity made to the owner or annuitant (as applicable) to the extent
such distributions do not exceed the qualified higher education expenses (as
defined in Section 72(t)(7) of the Code) of the owner or annuitant (as
applicable) for the taxable year; and (i) distributions from an Individual
Retirement Annuity made to the owner or annuitant (as applicable) which are
qualified first-time home buyer distributions (as defined in Section 72(t)(8) of
the Code.) The exceptions stated in (d) and (f) above do not apply in the case
of an Individual Retirement Annuity. The exception stated in (c) above applies
to an Individual Retirement Annuity without the requirement that there be a
separation from service.

With respect to (c) above, if the series of substantially equal periodic
payments is modified before the later of your attaining age 59 1/2 or 5 years
from the date of the first periodic payment, then the tax for the year of the
modification is increased by an amount equal to the tax which would have been
imposed (the 10% penalty tax) but for the exception, plus interest for the tax
years in which the exception was used. 

Generally, distributions from a qualified plan must begin no later than April
1st of the calendar year following the later of (a) the year in which the
employee attains age 70 1/2 or (b) the calendar year in which the employee
retires. The date set forth in (b) does not apply to an Individual Retirement
Annuity. Required distributions do not apply to a Roth IRA during the lifetime
of the Owner. Required distributions must be over a period not exceeding the
life expectancy of the individual or the joint lives or life expectancies of the
individual and his or her designated beneficiary. If the required minimum
distributions are not made, a 50% penalty tax is imposed as to the amount not
distributed.

               Tax Sheltered Annuities - Withdrawal Limitations

The Code limits the withdrawal of amounts attributable to contributions made
pursuant to a salary reduction agreement (as defined in Section 403(b)(11) of
the Code) to circumstances only when the owner: (1) attains age 59 1/2; (2)
separates from service; (3) dies; (4) becomes disabled (within the meaning of
Section 72(m)(7) of the Code); or (5) in the case of hardship. However,
withdrawals for hardship are restricted to the portion of the contract owner's
value which represents contributions made by the owner and does not include any
investment results. The limitations on withdrawals became effective on January
1, 1989 and apply only to salary reduction contributions made after December 31,
1988, to income attributable to such contributions and to income attributable to
amounts held as of December 31, 1988. The limitations on withdrawals do not
affect transfers between tax sheltered annuity plans. Contract owners should
consult their own tax counsel or other tax adviser regarding any distributions.

            Section 457 Deferred Compensation ("Section 457") Plans

Employees of (and independent contractors who perform services for) certain
state and local governmental units, or certain tax-exempt employers, may
participate in a Section 457 plan of the employer, allowing them to defer part
of their salary or other compensation. The amount deferred, and accrued income
thereon, will not be taxable until it is paid or otherwise made available to the
employee.      




                                       16

<PAGE>
 
    
The maximum amount that can be deferred under a Section 457 plan in any tax year
is generally one-third of the employee's includible compensation, up to $8,000
(in 1998). Includible compensation means earnings for services rendered to the
employer which are includible in the employee's gross income, excluding the
contributions under the Section 457 plan or a Tax-Sheltered Annuity. Certain
catch-up deferrals are permitted during the last three (3) years before an
employee attains normal retirement age. The contract purchased is issued to the
employer, and the employee has no rights or vested interest in the contract. All
contract value must be held for the exclusive benefit of the employee, and
payments can only be made in accordance with Section 457 plan provisions.
Presently, tax-free transfers of assets in a section 457 plan can only be made
to another section 457 plan in certain limited cases.

Purchasers of contracts for use with Section 457 plans should obtain competent
tax advice as to the tax treatment and suitability of such an investment.

Report Of Independent Accountants

To the Contract Owners of Massachusetts Mutual Variable Annuity Separate Account
2 and the Board of Directors of Massachusetts Mutual Life Insurance Company 

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets present fairly, in
all material respects, the financial position of each of the divisions of the
Flex Annuity IV (Non-Qualified) segment of Massachusetts Mutual Variable Annuity
Separate Account 2 (hereafter referred to as "the Account") at December 31,
1998, the results of each of their operations for the year then ended and the
changes in each of their net assets for each of the two years in the period then
ended, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Account's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of investments owned at
December 31, 1998 by correspondence with the investment company, provide a
reasonable basis for the opinion expressed above.

Massachusetts Mutual Variable Annuity Separate Account 2-Flex-Annuity IV (Non-
Qualified)

Notes To Financial Statements

1.   HISTORY

     Massachusetts Mutual Variable Annuity Separate Account 2 ("Separate Account
     2") is a separate investment account established on October 14, 1981 by
     Massachusetts Mutual Life Insurance Company ("MassMutual"). Separate
     Account 2 operates as a registered unit investment trust pursuant to the
     Investment Company Act of 1940.

     MassMutual maintains two segments within Separate Account 2. The segments
     are Flex-Annuity IV (Non-Qualified) and Flex Extra (Non-Qualified). These
     notes and the financial statements presented herein, with the exception of
     Note 9, describe and consist only of the Flex-Annuity IV (Non-Qualified)
     segment (the "Segment").

2.   INVESTMENT OF THE SEGMENT'S ASSETS

     The Segment maintains four divisions. The MML Equity Division invests in
     shares of MML Equity Fund, the MML Money Market Division invests in shares
     of MML Money Market Fund, the MML Managed Bond Division invests in shares
     of MML Managed Bond Fund and the MML Blend Division invests in shares of
     MML Blend Fund.

     MML Equity Fund, MML Money Market Fund, MML Managed Bond Fund and MML Blend
     Fund are four of six separate series of shares of the MML Series Investment
     Fund (the "MML Trust"). The MML Trust is a no-load, open-end, management
     investment company registered under the Investment Company Act of 1940.
     MassMutual serves as investment manager of the MML Trust David L. Babson &
     Company, Inc. ("Babson"), a controlled subsidiary of MassMutual, serves as
     the investment sub-adviser to MML Equity Fund and the Equity Sector of the
     MML Blend Fund.

3.   SIGNIFICANT ACCOUNTING POLICIES

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

     A. Investment Valuation

     The investments in MML Equity Fund, MML Money Market Fund, MML Managed Bond
     Fund and MML Blend Fund are each stated at market value which is the net
     asset value of each of the respective 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.

     C. Federal Income Taxes

     Operations of the Segment form a part of the total operations of
     MassMutual, and the Segment is not taxed separately. MassMutual is taxed as
     a life insurance company under the provisions of the 1986 Internal Revenue
     Code, as amended. The Segment 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 the Segment's investment
     performance. Accordingly, no provision for federal income tax has been
     made. MassMutual may, however, make such a charge in the future if an
     unanticipated change of current law results in a company tax liability
     attributable to the Segment.

Notes To Financial Statements (Continued)

     D. Annuitant Mortality Fluctuation Reserve

     The Segment maintains a reserve as required by regulatory authorities to
     provide for mortality losses incurred. The reserve is increased quarterly
     for mortality gains and its proportionate share of any increases in value.
     The reserve is charged quarterly for mortality losses and its proportionate
     share of any decreases in value. Transfers to or from MassMutual are then
     made quarterly to adjust the Segment. Net transfers from the Segment to
     MassMutual totaled $70,343 and $29,402 for the years ended December 31,
     1998 and 1997. The reserve is subject to a maximum of 3% of the Segment's
     annuity reserves. Any mortality losses in excess of this reserve will be
     assumed by MassMutual. The reserve is not available to owners of Contracts
     except to the extent necessary to cover mortality losses under the
     Contracts.

     E. Annuity Reserves

     Annuity reserves are developed by using accepted actuarial methods and are
     computed using the 1971 Individual Annuity Mortality Table, as modified.

     F. 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 FOR MORTALITY AND EXPENSE RISKS

     Daily charges for mortality and expense risks assumed by MassMutual are
     made which are equivalent on an annual basis to 1.25% of the value of the
     Segment's Contracts.

5.   DISTRIBUTION AGREEMENT

     MML Investors Services, Inc. ("MMLISI"), a wholly-owned subsidiary of
     MassMutual, serves as the principal underwriter of the contracts. MMLISI is
     registered as a broker-dealer under the Securities Exchange Act of 1934 and
     is a member of the National Association of Securities Dealers, Inc. The
     contracts are no longer offered for sale to the public. Contract owners may
     continue, however, to make purchase payments under existing contracts.
     MMLISI is the current broker-dealer for the existing contracts.

     Pursuant to the underwriting and servicing agreements, commissions or other
     fees due to registered representatives for servicing the contracts are paid
     by MassMutual on behalf of MMLISI. MMLISI also receives compensation for
     its activities as underwriter of the contracts.

Report of Independent Accountants

To the Contract Owners of Massachusetts Mutual Variable Annuity Separate 
Account 1 and the Board of Directors of Massachusetts Mutual Life Insurance 
Company

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets present fairly, in
all material respects, the financial position of each of the divisions of the
Variable Annuity Fund 4 and Flex Annuity IV (Qualified) segments of
Massachusetts Mutual Variable Annuity Separate Account 1 (hereafter referred to
as "the Account") at December 31, 1998, the results of each of their operations
for the year then ended and the changes in each of their net assets for each of
the two years in the period then ended, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Account's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which 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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of investments owned at December 31, 1998 by correspondence with
the investment company, provide a reasonable basis for the opinion expressed
above.

Massachusetts Mutual Variable Annuity Separate Account 1 -Variable Annuity Fund
4 and Flex-Annuity IV (Qualified)

Notes To Financial Statements

1. HISTORY

   Massachusetts Mutual Variable Annuity Separate Account 1 ("Separate Account
   1") is a separate investment account established on April 8, 1981 by
   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.

   MassMutual maintains three segments within Separate Account 1. The segments
   are Variable Annuity Fund 4, Flex-Annuity IV (Qualified) and Flex Extra
   (Qualified). These notes and the financial statements presented herein, with
   the exception of Note 9, describe and consist only of the Variable Annuity
   Fund 4 and Flex-Annuity IV (Qualified) segments (the "Segment").

2. INVESTMENT OF THE SEGMENT'S ASSETS

   The Variable Annuity Fund 4 and the Flex-Annuity IV (Qualified) segments each
   have four divisions. The MML Equity Division invests in shares of MML Equity
   Fund, the MML Money Market Division invests in shares of MML Money Market
   Fund, the MML Managed Bond Division invests in shares of MML Managed Bond
   Fund and the MML Blend Division invests in shares of MML Blend Fund.

   MML Equity Fund, MML Money Market Fund, MML Managed Bond Fund and MML Blend
   Fund are four of the six separate series of shares of the MML Series
   Investment Fund (the "MML Trust"). The MML Trust is a no-load, open-end,
   management investment company registered under the Investment Company Act of
   1940. MassMutual serves as investment manager of the MML Trust. David L.
   Babson and Company, Inc. ("Babson"), a controlled subsidiary of MassMutual,
   serves as the investment sub-adviser to MML Equity Fund and the Equity Sector
   of the MML Blend Fund.

3. SIGNIFICANT ACCOUNTING POLICIES

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

   A. Investment Valuation

   Investments in MML Equity Fund, MML Money Market Fund, MML Managed Bond Fund
   and MML Blend Fund are each stated at market value which is the net asset
   value of each of the respective 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 the Segment form a part of the total operations of MassMutual,
   and the Segment is not taxed separately. MassMutual is taxed as a life
   insurance company under the provisions of the 1986 Internal Revenue Code, as
   amended. The Segment 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 the Segment's investment
   performance. Accordingly, no provision for federal income tax has been made.
   MassMutual may, however, make such a charge in the future if an unanticipated
   change of current law results in a company tax liability attributable to the
   Segment.

   D. Annuitant Mortality Fluctuation Reserve

   The Segment maintains a reserve as required by regulatory authorities to
   provide for mortality losses incurred. The reserve is increased quarterly for
   mortality gains and its proportionate share of any increases in value. The
   reserve is charged quarterly for mortality losses and its proportionate share
   of any decreases in value. Transfers to or from MassMutual are then made
   quarterly to adjust the Segments. Net transfers from the Segments to
   MassMutual totaled $162,413 for the year ended December 31, 1998 and net
   transfers from MassMutual to the Segments totaled $31,303 for the year ended
   December 31, 1997. The reserve is subject to a maximum of 3% of the Segment's
   annuity reserves. Any mortality losses in excess of this reserve will be
   assumed by MassMutual. The reserve is not available to owners of Contracts
   except to the extent necessary to cover mortality losses under the Contracts.

   E. Annuity Reserves

   Annuity reserves are developed by using accepted actuarial methods and are
   computed using the 1971 Individual Annuity Mortality Table, as modified.

   F. 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 FOR MORTALITY AND EXPENSE RISKS

   A. Variable Annuity Fund 4 Contracts

   Currently, daily charges for mortality and expense risks assumed by
   MassMutual are made which are equivalent on an annual basis to 0.730% of the
   value of the Variable Annuity Fund 4 Contracts. Effective on January 1 of any
   year after the first Contract year, the daily charge made for the assumption
   of mortality and expense risks will be as determined by MassMutual, but in no
   event will such charge be at an annual rate of more than 1.2045% of the value
   of the Variable Annuity Fund 4 Contracts.

   B. Flex-Annuity IV (Qualified) Contracts

   Daily charges for mortality and expense risks assumed by MassMutual are made
   which are equivalent on an annual basis to 1.25% of the value of the
   Flex-Annuity IV Contracts.

5.   DISTRIBUTION AGREEMENT

     MML Investors Services, Inc. ("MMLISI"), a wholly-owned subsidiary of
     MassMutual, serves as the principal underwriter of the contracts. MMLISI is
     registered as a broker-dealer under the Securities Exchange Act of 1934 and
     is a member of the National Association of Securities Dealers, Inc. The
     Contracts are no longer offered for sale to the public. Contract owners may
     continue, however, to make purchase payments under existing contracts.

     Pursuant to the underwriting and servicing agreements, commissions or other
     fees due to registered representatives for selling and servicing the
     contracts are paid by MassMutual on behalf of MMLISI. MMLISI also receives
     compensation for its activities as underwriter of the contracts.

Report Of Independent Accountants

To the Board of Directors and Policyholders of
Massachusetts Mutual Life Insurance Company

We have audited the accompanying statutory statements of financial position of
Massachusetts Mutual Life Insurance Company as of December 31, 1998 and 1997,
and the related statutory statements of income and changes in policyholders'
contingency reserves, and of cash flows for each of the three years in the
period ended December 31, 1998. 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 in Note 1, these financial statements were prepared in conformity
with accounting practices prescribed or permitted by the Division of Insurance
of the Commonwealth of Massachusetts, 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, are presumed to be
material.

In our opinion, because of the effects of the matter discussed in the preceding
paragraph, the financial statements audited by us do not present fairly, in
conformity with generally accepted accounting principles, the financial position
of Massachusetts Mutual Life Insurance Company as of December 31, 1998 and 1997,
or the results of its operations or its cash flows for each of the three years
in the period ended December 31, 1998.

In our opinion, the financial statements audited by us present fairly, in all
material respects, the financial position of Massachusetts Mutual Life Insurance
Company as of December 31, 1998 and 1997, and the results of its operations and
its cash flows for each of the three years in the period ended December 31,
1998, on the basis of accounting described in Note 1.

Notes To Statutory Financial Statements

    Massachusetts Mutual Life Insurance Company ("the Company") is a mutual life
    insurance company and as such has no shareholders. The Company's primary
    business is individual life insurance, annuity and disability income
    products distributed primarily through career agents. The Company also
    provides either directly or through its subsidiaries, a wide range of
    pension products and services, as well as investment services to
    individuals, corporations and institutions in all 50 states and the District
    of Columbia.

    On March 1, 1996, the operations of the former Connecticut Mutual Life
    Insurance Company ("Connecticut Mutual") were merged into the Company. This
    merger was accounted for under the pooling of interests method of
    accounting. For the purposes of this presentation, these financial
    statements reflect historical amounts giving retroactive effect as if the
    merger had occurred on January 1, 1996 in conformity with the practices of
    the National Association of Insurance Commissioners ("NAIC") and the
    accounting practices prescribed or permitted by the Division of Insurance of
    the Commonwealth of Massachusetts. In 1996, merger-related expenses totaling
    $66.1 million were recorded in the Statutory Statement of Income. On the
    merger date, policyholders' reserves attributable to disability income
    contracts were strengthened by $75.0 million, investment reserves for real
    estate were increased by $49.8 million and net prepaid pension assets were
    increased by $10.4 million with all adjustments reflected as a charge to
    policyholders' contingency reserves.

    On March 31, 1996, the Company sold MassMutual Holding Company Two, Inc., a
    wholly-owned subsidiary, and its subsidiaries, including Mirus Life
    Insurance Company (formerly the MML Pension Insurance Company; currently
    doing business as "UniCARE"), which comprised the Company's group life and
    health business, to WellPoint Health Networks, Inc. The Company received
    total consideration of $402.2 million ($340.0 million in cash and $62.2
    million in notes receivable) and recognized a before tax gain of $187.9
    million. The Company, pursuant to a 1994 reinsurance agreement, cedes its
    group life, accident and health business to UniCARE.

1.  SUMMARY OF ACCOUNTING PRACTICES

    The accompanying statutory financial statements, have been prepared in
    conformity with the statutory accounting practices of the NAIC and the
    accounting practices prescribed or permitted by the Division of Insurance of
    the Commonwealth of Massachusetts and are different in some respects from
    financial statements prepared in accordance with generally accepted
    accounting principles ("GAAP"). 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 GAAP would require these expenses to be capitalized and
    recognized over the life of the policies; (b) policy reserves are based upon
    statutory mortality, morbidity 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 reported 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 and variable life products,
    variable annuities and investment related products are reported as premium
    income and changes in reserves, whereas under GAAP, these payments would be
    recorded as deposits to policyholders' account balances.

    In March 1998, the NAIC adopted the Codification of Statutory Accounting
    Principles ("Codification"). Codification provides a comprehensive guide of
    statutory accounting principles for use by insurers in all states and is
    expected to become effective no later than January 1, 2001. The effect of
    adopting Codification shall be reported as an adjustment to policyholders'
    contingency reserves on the effective date. The Company is currently
    reviewing the impact of Codification; however, since the Division of
    Insurance of the Commonwealth of Massachusetts has not approved
    Codification, the ultimate impact cannot be determined at this time.

Notes To Statutory Financial Statements (Continued)

    The preparation of 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 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 these financial
    statements.

    Certain 1997 and 1996 amounts have been reclassified to conform with the
    current year presentation.

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

A.  Investments

    Bonds and stocks are valued in accordance with rules established by the
    NAIC. Generally, bonds are valued at amortized cost, preferred stocks in
    good standing at cost, and common stocks, except for unconsolidated
    subsidiaries, at fair value.

    Mortgage loans are valued at unpaid principal net of unamortized premium or
    discount. The Company discontinues the accrual of interest on mortgage loans
    which are delinquent more than 90 days or when collection is uncertain. Real
    estate is valued at cost less accumulated depreciation, impairment
    allowances and mortgage encumbrances. Encumbrances totaled $63.5 million in
    1998 and $14.2 million in 1997. Depreciation on investment real estate is
    calculated using the straight-line and constant yield methods.

    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.

    Investments in unconsolidated subsidiaries and affiliates, joint ventures
    and other forms of partnerships are included in other investments on the
    Statutory Statement of Financial Position and are accounted for using the
    equity method.

    In compliance with regulatory requirements, the Company maintains an Asset
    Valuation Reserve ("AVR") and an Interest Maintenance Reserve ("IMR"). The
    AVR and other investment reserves stabilize the policyholders' contingency
    reserves against fluctuations in the value of stocks, as well as declines in
    the value of bonds, mortgage loans and real estate investments. The IMR
    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 interest related hedging activities. These interest rate
    related gains and losses are amortized into income using the grouped method
    over the remaining life of the investment sold or over the remaining life of
    the underlying asset. Net realized after tax capital gains of $189.1 million
    in 1998, $95.4 million in 1997 and $73.1 million in 1996 were charged to the
    IMR. Amortization of the IMR into net investment income amounted to $40.3
    million in 1998, $31.0 million in 1997, and $26.9 million in 1996.

    Realized capital gains and losses, less taxes, not includible in the IMR,
    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 policyholders' contingency reserves.

B.  Separate Accounts

    Separate account assets and liabilities represent segregated funds
    administered and invested by the Company for the benefit of pension,
    variable annuity and variable life insurance contractholders. Assets consist
    principally of marketable securities reported at fair value. Premiums,
    benefits and expenses of the separate


                                     FF-8
<PAGE>
 
Notes To Statutory Financial Statements (Continued)

    accounts are reported in the Statutory Statement of Income. The Company
    receives administrative and investment advisory fees from these accounts.

    Net transfers to separate accounts of $821.3 million, $355.7 million and
    $636.5 million in 1998, 1997 and 1996, respectively, are included in the
    addition of policyholders' reserves and funds.

C.  Non-admitted Assets

    Assets designated as "non-admitted" (principally certain furniture,
    equipment and other receivables) are excluded from the Statutory Statement
    of Financial Position by an adjustment to policyholders' contingency
    reserves.

D.  Policyholders' Reserves and Funds

    Policyholders' reserves for life insurance contracts are developed using
    accepted actuarial methods computed principally on the net level premium and
    the Commissioners' Reserve Valuation Method bases using the American
    Experience and the 1941, 1958 and 1980 Commissioners' Standard Ordinary
    mortality tables with assumed interest rates ranging from 2.5 to 6.75
    percent.

    Reserves for individual annuities, guaranteed investment contracts and
    deposit administration and immediate participation guarantee contracts are
    based on accepted actuarial methods principally at interest rates ranging
    from 2.25 to 11.25 percent. Reserves for policies and contracts considered
    investment contracts have a carrying value of $7,734.6 million and $8,077.9
    million at December 31, 1998 and 1997, respectively with a fair value of
    $7,940.6 million and $8,250.0 million at December 31, 1998 and 1997,
    respectively, as determined by discounted cash flow projections.

    Disability income policy reserves are generally calculated using the two-
    year preliminary term, net level premium and fixed net premium methods and
    various morbidity tables.

    The Company made certain changes in the valuation of policyholders' reserves
    which increased policyholders' contingency reserves by $8.6 million in 1998
    and decreased policyholders' contingency reserves by $55.4 million and $72.2
    million in 1997 and 1996, respectively.

E.  Premium and Related Expense Recognition

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

F.  Policyholders' Dividends

    The Board of Directors annually approves dividends to be paid in the
    following year. These dividends are allocated to reflect the relative
    contribution of each group of policies to policyholders' contingency
    reserves and consider investment and mortality experience, expenses and
    federal income tax charges. The liability for policyholders' dividends is
    equal to the estimated amount of dividends to be paid in the following
    calendar year.

G. Cash and Short-term Investments

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

H. Policyholders' Contingency Reserves

   Policyholders' contingency reserves represent surplus of the Company as
   reported to regulatory authorities and are intended to protect policyholders
   against possible adverse experience.

2. SURPLUS NOTES

   The Company issued surplus notes of $100.0 million at 7.50 percent and $250.0
   million at 7.625 percent in 1994 and 1993, respectively. These notes are
   unsecured and subordinate to all present and future indebtedness of the
   Company, policy claims and prior claims against the Company as provided by
   the Massachusetts General Laws. Issuance was approved by the Commissioner of
   Insurance of the Commonwealth of Massachusetts ("the Commissioner").

   All payments of interest and principal are subject to the prior approval of
   the Commissioner. Sinking fund payments are due as follows: $62.5 million in
   2021, $87.5 million in 2022, $150.0 million in 2023 and $50.0 million in
   2024.

   Interest on the notes issued in 1994 is scheduled to be paid on March 1 and
   September 1 of each year, to holders of record on the preceding February 15
   or August 15, respectively. Interest on the notes issued in 1993 is scheduled
   to be paid on May 15 and November 15 of each year, to holders of record on
   the preceding May 1 or November 1, respectively. Interest expense is not
   recorded until approval for payment is received from the Commissioner.
   Interest of $26.6 million was approved and paid in 1998, 1997 and 1996.

   The proceeds of the notes, less a $24.4 million reserve in 1998, and a $28.3
   million reserve in 1997 for contingencies associated with the issuance of the
   notes, are recorded as a component of the Company's policyholders'
   contingency reserves as permitted by the Division of Insurance. These surplus
   note reserves are included in asset valuation and other investment reserves
   on the Statutory Statement of Financial Position.

3. BENEFIT PLANS

   The Company provides multiple benefit plans to employees, agents and retirees
   including retirement plans and life and health benefits.

   Retirement Plans

   The Company has two non-contributory defined benefit plans covering
   substantially all of its employees. One plan includes active employees and
   retirees previously employed by Connecticut Mutual Life Insurance Company
   which merged with MassMutual in 1996; the other plan includes all other
   eligible employees and retirees. Benefits are based on the employees' years
   of service, compensation during the last five years of employment and
   estimated social security retirement benefits. The Company accounts for these
   plans following Financial Accounting Standards Board Statement No. 87,
   "Employers' Accounting for Pensions". Accordingly, as permitted by the
   Massachusetts Division of Insurance, the Company has recognized a pension
   asset of $216.0 million and $157.4 million at December 31, 1998 and 1997,
   respectively. Company policy is to fund pension costs in accordance with the
   requirements of the Employee Retirement Income Security Act of 1974 and,
   based on such requirements, no funding was required for the years ended
   December 31, 1998, and 1997. The assets of the plans are invested in the
   Company's general account and separate accounts.


                                     FF-10
<PAGE>
 
Notes To Statutory Financial Statements (Continued)

   The Company also has defined contribution plans for employees and agents. The
   Company funds the plans by matching employee contributions, subject to
   statutory limits. Company contributions and any earnings on them are vested
   based on years of vesting service using a graduated vesting schedule in 20
   percent increments over a five-year period.

   Life and Health

   Life and health insurance benefits are provided to employees and agents
   through group insurance contracts. Substantially all of the Company's
   employees and agents may become eligible for continuation of certain of these
   benefits if they retire as active employees or agents of the Company. The
   Company adopted the National Association of Insurance Commissioners'
   accounting standard for post retirement life and health benefit costs,
   requiring these benefits to be accounted for using the accrual method for
   employees and agents eligible to retire and current retirees. The initial
   transition obligation of $137.9 million is being amortized over twenty years
   through 2012. During 1998, the Company transferred the administration of the
   retiree life and health plan benefit obligations and supporting assets to an
   unconsolidated subsidiary.

   The status of the defined benefit plans as of December 31 is as follows:

                                         Retirement          Life and Health

A one percent increase in the annual assumed inflation rate in medical cost
rates would increase the 1998 accumulated postretirement benefit liability and
benefit expense by $9.2 million and $1.1 million, respectively. A one percent
decrease in the annual assumed inflation rate in medical costs rates would
decrease the 1998 accumulated postretirement benefit liability and benefit
expense by $8.5 million and $1.0 million, respectively.

Notes To Statutory Financial Statements (Continued)

   The expense charged to operations for all employee benefit plans is $32.1
   million in 1998, $23.9 million in 1997 and $38.1 million in 1996. In 1997,
   there was a significant reduction in plan participants in the Connecticut
   Mutual Plan which resulted in recognition of a pension plan curtailment gain
   of $10.7 million.

4. RELATED PARTY TRANSACTIONS

   The company has management and service contracts or cost sharing arrangements
   with various subsidiaries and affiliates whereby the Company, for a fee, will
   furnish a subsidiary or affiliate, as required, operating facilities, human
   resources, computer software development and managerial services. Fees earned
   under the terms of the contracts or arrangements were $205.0 million and
   $137.3 million for 1998 and 1997, respectively.

   The Company has reinsurance agreements with its subsidiaries, C.M. Life
   Insurance Company and MML Bay State Life Insurance Company, including stop-
   loss and modified coinsurance agreements on life insurance products. Total
   premiums assumed on these agreements were $38.4 million in 1998, $40.9
   million in 1997 and $44.1 million in 1996.

5. FEDERAL INCOME TAXES

   Provision for federal income taxes is based upon the Company's estimate of
   its current 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, acquisition costs and restructuring costs and of permanent
   differences such as the equity tax, resulted in effective tax rates which
   differ from the statutory tax rate.

   The Company plans to file its 1998 federal income tax return on a
   consolidated basis with its eligible life affiliates and non-life affiliates.
   C.M. Life Insurance Company, which is not an eligible life affiliate, files a
   separate return. The Company and its eligible life insurance and non-life
   affiliates are subject to a written tax allocation agreement, which allocates
   the group's consolidated tax liability for payment purposes. Generally, the
   agreement provides that affiliates with losses shall be compensated for the
   use of their losses and credits by other affiliates.

   The Internal Revenue Service has completed examining the Company's income tax
   returns through the year 1992 for Massachusetts Mutual and 1995 for
   Connecticut Mutual, and is currently examining Massachusetts Mutual for the
   years 1993 and 1994. The Company believes adjustments which may result from
   such examinations will not materially affect its financial position.

   Components of the formula authorized by the Internal Revenue Service for
   determining deductible policyholder dividends have not been finalized for
   1998 or 1997. The Company records the estimated effects of anticipated
   revisions in the Statutory Statement of Income.

   Federal tax payments were $152.4 million in 1998, $353.4 million in 1997 and
   $330.7 million in 1996.

6. INVESTMENTS

   The Company maintains a diversified investment portfolio. Investment policies
   limit concentration in any asset class, geographic region, industry group,
   economic characteristic, investment quality or individual investment. In the
   normal course of business, the Company enters into commitments to purchase
   privately placed bonds and to issue mortgage loans.

   Proceeds from sales of investments in bonds were $11,663.4 million during
   1998, $11,427.8 million during 1997 and $6,390.7 million during 1996. Gross
   capital gains of $331.8 million in 1998, $200.7 million in 1997 and $188.8
   million in 1996 and gross capital losses of $47.3 million in 1998, $68.8
   million in 1997 and $255.5 million in 1996 were realized on those sales,
   portions of which were included in the IMR. The estimated fair value of non-
   publicly traded bonds is determined by the Company using a pricing matrix and
   quoted market prices for publicly traded bonds.

B. Stocks

   Common stocks, except for unconsolidated subsidiaries, had a cost of $238.4
   million in 1998 and $250.3 million in 1997.

C. Mortgages

   The fair value of mortgage loans, as determined from a pricing matrix for
   performing loans and the estimated underlying real estate value for non-
   performing loans, was $6,178.8 million and $5,039.1 million at December 31,
   1998 and 1997, respectively.

   The Company had restructured loans with book values of $126.6 million, and
   $202.3 million at December 31, 1998 and 1997, respectively. These loans
   typically have been modified to defer a portion of the contractual interest
   payments to future periods. Interest deferred to future periods totaled $0.1
   million in 1998, $5.1 million in 1997 and $2.2 million in 1996. At December
   31, 1998, scheduled commercial mortgage loan maturities were as follows: 
   1999 - $341.0 million; 2000 - $333.0 million; 2001 - $305.2 million; 2002 -
   $210.6 million; 2003 - $299.0 million; and $3,106.4 million thereafter.

D. Policy Loans

   Policy loans are recorded at cost as it is not practicable to determine the
   fair value since they do not have a stated maturity.

E. Other

   Preferred stocks in good standing had fair values of $116.0 million in 1998
   and $145.5 million in 1997, using a pricing matrix for non-publicly traded
   stocks and quoted market prices for publicly traded stocks.

Notes To Statutory Financial Statements (Continued)

   The carrying value of investments which were non-income producing for the
   preceding twelve months was $13.2 million and $5.7 million at December 31,
   1998 and 1997, respectively.

7. PORTFOLIO RISK MANAGEMENT

   The Company manages its investment risks, primarily to reduce interest rate
   and duration imbalances determined in asset/liability analyses. The fair
   values of these financial instruments, described below, which are not
   recorded in the financial statements, unless otherwise noted, are based upon
   market prices or prices obtained from brokers. The Company does not hold or
   issue these financial instruments for trading purposes.

   The notional amounts described do not represent amounts exchanged by the
   parties and, thus, are not a measure of the exposure of the Company. The
   amounts exchanged are calculated on the basis of the notional amounts and the
   other terms of the instruments, which relate to interest rates, exchange
   rates, security prices or financial or other indexes.

   The Company utilizes interest rate swap agreements, options, and purchased
   caps and floors to reduce interest rate exposures arising from mismatches
   between assets and liabilities and to modify portfolio profiles to manage
   other risks identified. Under interest rate swaps, the Company agrees to an
   exchange, at specified intervals, between streams of variable rate and fixed
   rate interest payments calculated by reference to an agreed-upon notional
   principal amount. Gains and losses realized on the termination of contracts
   are deferred and amortized through the IMR over the remaining life of the
   associated contract. IMR amortization is included in net investment income on
   the Statutory Statement of Income. Net amounts receivable and payable are
   accrued as adjustments to investment income and included in other assets on
   the Statutory Statement of Financial Position. At December 31, 1998 and 1997,
   the Company had swaps with notional amounts of $4,382.0 million and $3,220.2
   million, respectively. The fair values of these instruments were $84.1
   million at December 31, 1998 and $20.9 million at December 31, 1997.

   Options grant the purchaser the right to buy or sell a security or enter into
   a derivative transaction at a stated price within a stated period. The
   Company's option contracts have terms of up to fifteen years. The amounts
   paid for options purchased are amortized into investment income over the life
   of the contract on a straight-line basis. Unamortized costs are included in
   other investments on the Statutory Statement of Financial Position. Gains and
   losses on these contracts are recorded at the expiration or termination date
   and are deferred and amortized through the IMR over the remaining life of the
   option contract. At December 31, 1998 and 1997, the Company had option
   contracts with notional amounts of $12,704.4 million and $5,388.2 million,
   respectively. The Company's credit risk exposure was limited to the
   unamortized costs of $92.5 million and $59.0 million, which had fair values
   of $161.9 million and $99.6 million at December 31, 1998 and 1997,
   respectively.

   Interest rate cap agreements grant the purchaser the right to receive the
   excess of a referenced interest rate over a stated rate calculated by
   reference to an agreed upon notional amount. Interest rate floor agreements
   grant the purchaser the right to receive the excess of a stated rate over a
   referenced interest rate calculated by reference to an agreed upon notional
   amount. Amounts paid for interest rate caps and floors are amortized into
   investment income over the life of the asset on a straight-line basis.
   Unamortized costs are included in other investments on the Statutory
   Statement of Financial Position. Amounts receivable and payable are accrued
   as adjustments to investment income and included in the Statutory Statement
   of Financial Position as other assets. Gains and losses on these contracts,
   including any unamortized cost, are recognized upon termination and are
   deferred and amortized through the IMR over the remaining life of the
   associated cap or floor agreement. At December 31, 1998 and 1997, the company
   had agreements with notional amounts of $4,337.9 million and $3,348.6
   million, respectively. The Company's credit risk exposure on these agreements
   is limited to the unamortized costs of $22.7 million and $18.2 million at
   December 31, 1998 and 1997, respectively. The fair values of these
   instruments were $43.9 million and $23.4 million at December 31, 1998 and
   1997, respectively.

Notes To Statutory Financial Statements (Continued)

   The Company enters into forward U.S. Treasury, and Government National
   Mortgage Association ("GNMA") and Federal National Home Mortgage Association
   ("FNMA") commitments for the purpose of managing interest rate exposure. The
   Company generally does not take delivery on forward commitments. These
   commitments are instead settled with offsetting transactions. Gains and
   losses on forward commitments are recorded when the commitment is closed and
   amortized through the IMR over the remaining life of the asset. At December
   31, 1998 and 1997, the Company had U. S. Treasury, GNMA and FNMA purchase
   commitments which will settle during the following year with contractual
   amounts of $603.4 million and $1,100.7 million, respectively. The fair values
   of these commitments were $604.1 million and $1,117.6 million, including net
   unrealized gains of $0.7 million and $16.9 million at December 31, 1998 and
   1997, respectively.

   The Company utilizes other agreements to reduce exposures to various risks.
   Notional amounts relating to these agreements totaled $384.2 million and
   $385.6 million at December 31, 1998 and 1997, respectively. The fair values
   of these instruments resulted in an unrealized gain of $7.2 million at
   December 31, 1998 and an unrealized loss of $6.8 million at December 31,
   1997.

   The Company is exposed to credit-related losses in the event of
   nonperformance by counterparties to derivative financial instruments. This
   exposure is limited to contracts with a positive fair value. The amounts at
   risk in a net gain position were $272.5 million and $146.7 million at
   December 31, 1998 and 1997, respectively. The Company monitors exposure to
   ensure counterparties are credit worthy and concentration of exposure is
   minimized. Additionally, collateral positions have been obtained with
   counterparties when considered prudent.

8. INVESTMENTS IN UNCONSOLIDATED SUBSIDIARIES

   MassMutual has two primary insurance subsidiaries, C.M. Life, which primarily
   writes variable annuities and universal life insurance, and MML Bay State,
   which primarily writes variable life and annuity business. MassMutual's
   wholly-owned non-insurance subsidiary MassMutual Holding Company, Inc.
   ("MMHC") owns subsidiaries which include retail and institutional asset
   management, registered broker dealer and international life and annuity
   operations.

   MassMutual accounts for the value of its investments in subsidiaries at their
   underlying net equity. Operating results for such subsidiaries are reflected
   as net unrealized capital gains in the Statement of Changes in Policyholders'
   Contingency Reserves. Net investment income is recorded by MassMutual to the
   extent that dividends are declared by the subsidiaries. The Company holds
   debt issued by MMHC and its subsidiaries of $1,111.3 million and $792.4
   million at December 31, 1998 and 1997, respectively.

   Below is summarized financial information for the unconsolidated subsidiaries
   as of December 31 and for the year then ended:

                                                  1998            1997

9.  REINSURANCE

    The Company has reinsurance agreements with other insurance companies in the
    normal course of business. In addition, the Company cedes the remainder of
    its group life and health business to UniCARE. Premiums, benefits to
    policyholders and provisions for future benefits are stated net of
    reinsurance. The Company remains liable to the insured for the payment of
    benefits if the reinsurer cannot meet its obligations under the reinsurance
    agreements. Total premiums ceded were $183.9 million in 1998, $294.6 million
    in 1997 and $793.5 million in 1996.

10. BUSINESS RISKS AND CONTINGENCIES

    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
    premium taxes. The Company believes such assessments in excess of amounts
    accrued will not materially affect its financial position, results of
    operations or liquidity.

    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.

11. SUBSIDIARIES AND AFFILIATED COMPANIES

Item 27.          Number of Contract Owners     
                      
                  As of February 26, 1999, 923 Separate Account 2 Contracts were
                  in force.     
    
Item  28.         Indemnification     

                  MassMutual 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 MassMutual pursuant to the
                  foregoing provisions, or otherwise, MassMutual 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 MassMutual
                  of expenses incurred or paid by a director, officer or
                  controlling person of MassMutual 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, MassMutual 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.

Re: Post-Effective Amendment No.18 to Registration Statement 
    No.2-75413 filed on Form N-4     

Ladies and Gentlemen:
    
This opinion is furnished in connection with the filing of Post-Effective
Amendment No.18 to Registration Statement No.2-75413 on Form N-4 under the
Securities Act of 1933 for Massachusetts Mutual Life Insurance Company's
("MassMutual") flexible premium variable annuity contract (the "Contract").
Massachusetts Mutual Variable Annuity Separate Account 2 issues the Contract.
         
As an attorney for MassMutual, I provide legal advice to MassMutual 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:     

l. MassMutual is a valid and subsisting corporation, organized and operated
under the laws of the Commonwealth of Massachusetts and is subject to regulation
by the Massachusetts Commissioner of Insurance.

2. Massachusetts Mutual Variable Annuity Separate Account 2 is a separate
account validly established and maintained by MassMutual in accordance with
Massachusetts 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
