Highlights

This prospectus describes the general provisions of the Flex Extra variable
annuity contracts. We offer two contracts: a flexible purchase payment contract
and a single purchase payment contract. The contracts are the same, except that
there are:

(1)   different sales and administrative charges;

(2)   different minimum purchase payment amounts; and

(3)   certain differences associated with tax-qualified plans.

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. However,
this time period may vary by state. 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 the contract value or if you elect to begin receiving annuity payments
under the contract. The amount of the contingent deferred sales charge depends
on the type of contract you purchase, the length of time since we issued your
contract and the amount of your withdrawal or the amount you apply to an annuity
payment. The contingent deferred sales charge for the flexible purchase payment
contract ranges from 8% to 0%. The contingent deferred sales charge for the
single purchase payment contract ranges from 5% to 0%.

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: 

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

o     paid to your beneficiary after you die;

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

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

o     paid under an immediate annuity; or

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

The Internal Revenue 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.

excess of 0.11% of the average daily net asset value of these Funds through

Examples

The following examples are designed to help you understand the expenses in the
contracts. The examples show the cumulative expenses you would pay assuming you
invested $1,000 in a contract and allocated all of it to a fund that earned 5%
each year. All the expenses shown in the table of fees and expenses, including
the annual fund expenses, are assumed to apply.

There are two sets of examples. The first set of examples assumes you purchased
a single purchase payment contract and the second set of examples assumes you
purchased a flexible purchase payment contract.

The purpose of the Table of Fees and Expenses is to assist you in understanding
the various costs and expenses that you will incur. The table reflects expenses
of the separate account and the funds.

The examples for the single purchase payment contract reflect the $30 annual
administrative charge as an annual charge of 0.04%. This charge is based on an
anticipated average contract value of $75,000.

The examples for the flexible purchase payment contract reflect the $35 annual
administrative charge as an annual charge of 0.15%. The charge is based on an
anticipated average contract value of $23,333.

The examples do not reflect any premium taxes. However, premium taxes may apply.

The examples should not be considered a representation of past or future
expenses. Actual expenses may be greater or less than those shown.

There is an accumulation unit value history contained in Appendix A - Condensed

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 Extra Variable Annuity Contracts - General Overview

Flex Extra 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 payment, 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 Extra contracts, like all deferred
annuity con-tracts, 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 various investment choices. Your choices include
seven funds and one fixed interest account called the Guaranteed Principal
Account (GPA). 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 as well as the interest we credit on your value in the GPA.

At the beginning of the income phase, you can choose to receive annuity payments
on a variable basis, a 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.

The contract is available as a single purchase payment contract or a flexible
purchase payment contract.

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

o     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;

   
o     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";
    


                                                                               9
<PAGE>
 
o     deferred compensation plans for state and local governments and tax-exempt
      organizations established under the provisions of Section 457 of the Code;
      and

   
o     Individual Retirement Annuities established in accordance with Section 408
      of the Code. These are referred to as IRAs. This also includes Roth IRA's
      and those under a Simplified Employee Pension Plan or a Saving Incentive
      Match Plan (also called SIMPLE IRA).
    

Contracts issued by Separate Account 2 are 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. They may be purchased by a
Charitable Remainder Trust.

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 were there is:

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

o     a non-natural person;

o     a trust; or

o     an employer sponsored plan.

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.

In most states, we will not issue a flexible purchase contract to you if you are
75 1/2 years or older as of the date we proposed to issue the contract. In most
states, we will not issue a single purchase contract to you if you are 79 1/2
years or older as of the date we proposed to issue the contract.

As the owner of the contract, you exercise all rights under the contract. The
owner names the beneficiary.

Annuitant 

The annuitant is the person on whose life we base annuity payments.

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.

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.

A beneficiary who is the surviving spouse of the owner of a contract that we
issued as an IRA, may elect to treat the contract as if he/she were the contract
owner. Please call our Annuity Service Center for more information.


                                                                              11

Purchasing A Contract

Purchase Payments

Single Purchase Payment Contract:

o     Minimum - $25,000

o     Maximum - $1,000,000, without our prior approval

Flexible Purchase Payment Contract:

o     Minimum

      o     $2,000, if you intend to make only one purchase payment over the
            lifetime of the contract; or otherwise 

      o     $600, divided by the number of installments (not more than 12) which
            you expect to make each year.

o     Maximum - $1,000,000 total payments without our prior approval.

You can make additional purchase payments to your flexible purchase payment
contract of at least $50.

We have the right to reject any application or purchase payment.

You may make your initial purchase payment, along with your completed
application, by giving them to your agent. You can make additional purchase
payments:

o     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

o     by 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)

Allocation Of Purchase Payments

When you purchase your contract, you choose how we will apply your purchase
payment(s) among the investment choices. If you make additional purchase
payments under our flexible purchase payment contract, we will apply them in the
same way that you requested on your application, unless you tell us otherwise.

Once we receive your purchase payment and the necessary information at our
lockbox or Annuity Service Center, we will apply your first purchase payment
within 2 business days. If you do not give us all the information we need, we
will contact you to get it. If for some reason we are unable to complete the
issue process within 5 business days, we will either send back your money or get
your permission to keep it until we get all of the necessary information.

If you add more money to your contract by making additional purchase payments,
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.

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 7 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 7 funds that are listed below. We may add additional funds
in the future.

   
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

The Guaranteed Principal Account

   
You may allocate purchase payments to our fixed interest account referred to as
the Guaranteed Principal Account (GPA). Payments that you allocate to the GPA
become part of MassMutual's general account assets. You can also make transfers
of your contract value into or from the GPA with some restrictions.
    

You do not participate in the investment performance of the assets in the GPA.
Instead, we credit your contract with interest at a specified rate that we
declare in advance. We guarantee this rate will be at least 3.5% per year. We
may also credit a higher rate of interest at our discretion.

Although we are not obligated to credit interest at a rate higher than 3.5%, we
will credit and guarantee a secondary interest rate, that may be higher but will
never be lower than 3.5%, for each calendar year period. In addition, we may pay
a rate of interest in excess of the secondary guarantee for periods we deem
appropriate.

For TSAs, we credit interest on loaned amounts held in the GPA at a daily rate
equivalent to the greater of:

o     3.5% per year, or

o     the adjustable loan interest rate in effect, less an amount that will not
      exceed 4%.

Contract Value

Your contract value is the sum of your value in the separate account and the
GPA.

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 to the funds, 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 Oppenheimer Strategic Bond Fund/VA. When the
New York Stock Exchange closes on that Monday, we determine that the value of an
accumulation unit for the Oppenheimer Strategic Bond Fund/VA 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 Oppenheimer Strategic Bond Fund/VA.
    

Transfers

You can transfer all or part of your contract value among the funds and the GPA.
Transfers out of the GPA are subject to certain limitations. We have the right
to terminate or modify these transfer provisions.

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.

Transfers During the Accumulation Phase

You may transfer all or part of your assets among the funds or into the GPA
without charge. However, we reserve the right to limit transfers to once every
90 days. You may not make transfers during the period 30 days before your
contract enters the income phase.

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.


                                                                              15
<PAGE>
 
Transfers from the GPA to the funds are subject to the following restrictions:

(1)   You are limited to one transfer out of the GPA each contract year; and

(2)   Annual transfers out of the GPA cannot exceed 25% of the amount you have
      in the GPA on the date the transfer is made. However, if you transfer 25%
      of your contract value from the GPA for three consecutive years, the
      fourth consecutive annual transfer may be for the entire amount in the
      GPA, provided that no payments or transfers have been made into the GPA
      during the period.

If your contract is a TSA with a right to make loans, the maximum amount of any
transfer from the GPA is the lesser of:

(1)   25% of the amount in the GPA on the date the transfer is made; or

(2)   the amount in the GPA on the date the transfer is made, less the amount of
      any outstanding contract loan.

Finally, we reserve the right to:

(1)   limit the sum of any transfer and partial withdrawals from the GPA during
      any contract year to no more than 25% of the amount in the GPA on the date
      that the transfer or first partial withdrawal from the GPA is made during
      that contract year; and

(2)   prohibit transfers from the GPA to the MML Money Market Fund.

Transfers During the Income Phase.

You may not make any transfers during the Income Phase.

Automatic Transfers

We currently offer the following four automatic transfer programs:

o     Dollar Cost Averaging

o     Asset Allocation Program

o     Interest Sweep Option

o     GPA Liquidation Program

These programs are only available during the accumulation phase. You may
participate in only one of the automatic transfer programs at a time. We
currently do not charge you for participating in these programs, but we reserve
the right to do so in the future.

Dollar Cost Averaging Program

The Dollar Cost Averaging Program allows you to systematically transfer a set
amount from a selected fund to any of the other funds or to the GPA. By
allocating amounts on a regular schedule as opposed to allocating the total
amount at one particular time, you may be less susceptible to the impact of
market fluctuations.

Dollar Cost Averaging does not assure a profit and does not protect you against
loss in declining markets. Since Dollar Cost Averaging involves continuous
investment in securities regardless of fluctuating price levels of such
securities, you should consider your financial ability to continue the Dollar
Cost Averaging Program through periods of fluctuating price levels.

The minimum amount you can transfer is $500. You must have a minimum balance of
$6,000 in the originating fund in order to participate in the Dollar Cost
Averaging Program.

The minimum duration of participation in any Dollar Cost Averaging program is
currently 12 months. Dollar Cost Averaging transfers can be made monthly or
quarterly.

Your Dollar Cost Averaging option will terminate:

o     upon your death;

o     if we make the last transfer you selected;

o     if you request a loan on a TSA contract;

o     if you begin the income phase of your contract; or


16
<PAGE>
 
o     if we receive your written request to terminate the program at least 5
      business days prior to the next scheduled transfer date.

We have the right to modify, terminate or suspend the Dollar Cost Averaging
Program.

Asset Allocation Program

The asset allocation program allows you to periodically adjust the percentage of
your contract value allocated to selected investment choices. We will
automatically transfer money between investment choices to maintain your desired
allocation. With the asset allocation program, you may maintain a balanced and
diversified approach to investing, as decreases in one fund can be offset by
gains in another.

You can choose to have the transfers done quarterly, semi-annually, or annually.
However, you may only make annual transfers if you use the GPA in your asset
allocation program. If you are making annual transfers, you must maintain a
contract value of at least $6,000. If you are making semi-annual or quarterly
transfers, your minimum contract value must be $25,000. You may adjust your
allocations at any time.

Your Asset Allocation option will terminate:

o     upon your death;

o     if we make the last transfer you elected;

o     if your contract value falls below the minimum;

o     if you request a loan on a TSA contract;

o     if you begin the income phase of your contract; or

o     if we receive your written request to terminate the program at least 5
      business days prior to the next scheduled transfer date.

Interest Sweep Option

Under this program, we will automatically transfer earnings from your GPA
account to one or more selected funds. By allocating these earnings to the
funds, you can pursue further growth in the value of your contract through more
aggressive investments. However, the interest sweep option does not assure
profit and does not protect against loss in declining markets.

To participate in this program, you must have at least $6,000 in your GPA
account at the time of transfer. While the program is in effect, you can adjust
your allocations as necessary.

This service will terminate:

o     if your account balance falls below the required minimum amount in the
      GPA;

o     upon your death;

o     if you request a loan on a TSA contract;

o     if you begin the income phase of your contract; or

o     if we receive your written request to terminate the program at least 5
      business days prior to the next scheduled transfer date.

GPA Liquidation Program

Under the GPA liquidation program, you can automatically transfer 25% of your
GPA balance to one or more funds until your GPA balance is liquidated in the
fourth year. This option lets you systematically transfer your money into more
aggressive funds. The GPA liquidation program does not assure a profit and does
not protect you against loss in declining markets.

There are no required minimum balances, and the program will continue until all
your GPA account value is transferred. All transfers are made on an annual
basis. You may adjust your allocations at any time.

This service will terminate:

o     upon your death;

o     if you request a loan on a TSA contract;

o     if you begin the income phase of your contract;

o     if you add any money to the GPA through transfers or additional purchase
      payments during the 4-year period; or


                                                                              17
<PAGE>
 
o     if we receive your written request to terminate the program at least 5
      business days prior to the next scheduled transfer date.

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.

If you make a partial withdrawal, you must tell us from which investment choices
you want the withdrawal taken. You must withdraw at least $100 or the entire
value in a fund or the GPA, if less. If your request for a partial withdrawal
will reduce your contract value to less than $500, we will treat the request as
a full withdrawal of your contract value. Partial withdrawals may be subject to
a contingent deferred sales charge.

If you request a full withdrawal of your contract value, you may ask us to make
the payment in one sum or apply the amount to one or more payment options.

We reserve the right to limit the sum of any transfer and partial withdrawals
from the GPA during any contract year to no more than 25% of the amount in the
GPA on the date that the transfer or first partial withdrawal from the GPA is
made during that contract year.

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

o     less any applicable contingent deferred sales charge;

o     less any applicable premium tax;

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

Your withdrawal is effective on the business day we receive your written 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.

Automatic Withdrawal Option Program

This program provides for an automatic monthly, quarterly, semi-annual or annual
payment of at least $100. You may elect to receive payment amounts that are for
a constant dollar, a constant percentage or IRS minimum required distributions.
We may restrict the options available to you, depending on whether your contract
is qualified or non-qualified. Our Annuity Service Center can provide you with
complete information.

To initiate this program, your contract value must be at least $10,000.
Currently, we do not charge you to participate in this program, but we reserve
the right to charge up to $3.00 per withdrawal in the future. This program is
only available during the accumulation phase.

You must elect this program in writing. Once we accept the request, the program
will go into effect as of the date of the first regularly scheduled partial
withdrawal. You may elect to have your automatic withdrawal amounts transferred
electronically to your bank account.

You can make changes to your program by sending us a written request. However,
changes may only be made once each calendar year.

We consider withdrawals under the program to be one withdrawal for the contract
year for purposes of the free withdrawal provision. If you have not taken a
withdrawal earlier in the contract year, we will apply the 10% free withdrawal
to withdrawals under this program.

Your automatic withdrawal program ends:

o     upon your death;

o     if your contract value falls below $500;

o     if we process the last withdrawal you selected;

o     if you begin the income phase of your contract; or


18
<PAGE>
 
o     if we receive your written request to terminate the program at least 5
      business days prior to the next scheduled transfer date.

If you participate in this program, you may be subject to surrender charges.

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

Right to Make Loans from a TSA Contract

In some states, if your contract is a non-ERISA and non-Texas Optional
Retirement Program TSA, you may be able to make a loan under your contract. All
such loans must conform to the requirements of the Code. There are limitations
on the amount of loan you can make and there is a required loan repayment
schedule. If you default, the outstanding debt will be considered a taxable
distribution and we will do appropriate tax reporting. We will withdraw
sufficient contract value to repay the debt to the extent such withdrawals are
not restricted under the Code.

If you own a TSA Contract with an outstanding loan and are taking an eligible
distribution of your entire contract value, we will deduct any outstanding
contract debt from the amount you withdraw. If you make a partial withdrawal,
the contract value remaining after the withdrawal must not be less than: 

o     the amount of any outstanding loan, plus

o     interest on the loan for 12 months based on the loan interest rate then in
      effect, plus

o     any contingent deferred sales charge that would apply to such an amount
      otherwise withdrawn.

Amounts held in the GPA equal to the amount of any outstanding loan are not
available for withdrawal.


                                                                              19

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 are:

Insurance Charges

Each business day we deduct our insurance charges 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. The insurance charge has two parts:
(1) the mortality and expense risk charge and (2) the administrative expense
charge. The total insurance charges are 1.30%. We have the right to increase
these charges to a total of 1.40%.

Mortality and Expense Risk Charge

This charge is equal, on an annual basis, to 1.15% of the daily value of the
assets invested in each fund, after fund expenses are deducted. We can increase
this charge, but the charge will never exceed 1.25%. This charge is for:

o     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;

o     the expense risk that the current administrative expense and annual
      administrative charges will be insufficient to cover the actual cost of
      administering the contracts.

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

Administrative Expense Charge

This charge is equal, on an annual basis, to 0.15% of the daily value of the
assets invested in each fund, after expenses are deducted. We assess this
charge, together with the annual administrative charge, to reimburse us for all
the expenses associated with the administration of the contract and the separate
account. Some of these expenses are: preparation of the contract, confirmations,
annual reports and statements, maintenance of contract records, personnel costs,
legal and accounting fees, filing fees, and computer and systems costs.

Administrative Charge

Starting in the second contract year, we impose a charge against each contract
to reimburse us for expenses relating to the issuance and maintenance of the
contract. We deduct this charge on the first day of the contract year.

If you own a single purchase payment contract, we deduct $30 per contract year
as an administrative charge. The charge is $35 per contract year if you own a
flexible purchase payment contract. We may increase this charge, but it will not
exceed $50. We have set the administrative charge and the administrative expense
charge so that we will not make a profit on these charges.

We make this deduction from the funds you have selected in the order noted in
your contract and then from the GPA. The charge we impose against amounts in the
GPA will not be greater than 1% of your contract value in the GPA on the
contract anniversary.

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 on the amount you withdraw that
exceeds the free withdrawal amount. We may also apply the charge if you elect to
begin the income phase of your contract under certain annuity payment options.
We use this charge to cover certain expenses related to the sale of the
contract.


20
<PAGE>
 
The contingent deferred sales charge will be a percent of the amount you
withdraw or a percent of your contract value at the maturity date. The amount of
the charge depends on the length of time between when we issued your contract
and when you make a withdrawal or begin receiving annuity payments.

The contingent deferred sales charge is assessed as follows:

                                         Charge for                  Charge for

The total amount of the contingent deferred sales charge we deduct will not
exceed 8.5% of your total purchase payments.

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

o     Upon our payment of a death benefit;

o     If you are 59 1/2 or older, and you apply your entire contract value:

      o     under a fixed lifetime payment option;

      o     under a fixed annuity, fixed time payment option with payments for
            10 years or more;

      o     to purchase a single premium immediate life annuity issued by us or
            one of our affiliates;

      o     to purchase a single premium immediate annuity certain, with
            payments guaranteed for 10 years or more, issued by us or one of our
            affiliates.

o     If you apply your entire contract value:

      o     under a variable lifetime payment option; or 

      o     under a variable fixed-time payment option, with payments for 10
            years or more.

o     On a lump-sum payment equal to the present value of the remaining payments
      under a variable fixed-time payment option, if we had imposed a contingent
      deferred sales charge on the maturity date;

o     If you surrender your contract before April 30, 2000 and you use the
      proceeds of the surrender to purchase a new group annuity issued by us.
      The group annuity contract may be subject to charges upon withdrawal;

   
o     If you withdraw "excess contributions" to a plan qualifying for special
      income tax treatment. These types of plans are referred to as qualified
      plans. They include TSAs and IRAs. We look to the Internal Revenue Code
      for the definition and description of excess contributions;
    

o     If your contract was purchased by exchanging a previously issued
      MassMutual variable annuity contract where we waived the contingent
      deferred sales charge due to an earlier exchange or which was subject to
      an initial sales charge;

o     If you exchange a fixed annuity contract issued by us or any of our
      affiliates which has no surrender charge and has at least 60 days until
      its maturity date, for a single purchase payment contract;

o     If the bail out provision applies. The bail out provision applies if, at
      any time before your contract matures, the effective annual interest rate
      credited to the GPA falls below the specified interest rate for a calendar
      quarter. (New York requires that the values be in the GPA in order to take
      advantage of this provision.) The specified interest rate is equivalent to
      the average discount rate on the


                                                                              21
<PAGE>
 
      91-day U. S. Treasury bills during the preceding quarter, reduced by
      1.40%. Within 10 days after the effective annual interest rate credited to
      the GPA falls below the specified interest rate, we will send you a
      written notice. This notice will indicate that you may fully withdraw your
      contract value or begin receiving annuity payments without incurring a
      contingent deferred sales charge for a period of 60 days after we mail the
      notice to you.

   
Owners of certain IRA or non-qualified Flex Extra annuity contracts that are
beyond the contingent deferred sales charge period may exchange these contracts
for Panorama Premier contracts issued by us or our subsidiary, C.M. Life
Insurance Company. We call this the "Flex Extra Exchange Program". Any contract
value that you exchange to a Panorama Premier contract will not be subject to a
contingent deferred sales charge under the Panorama Premier contract. If you
make any additional purchase payments to the Panorama Premier contract, they
will be subject to a contingent deferred sales charge as assessed under the
Panorama Premier contract.
    

If you purchased your contract by exchanging a previously issued MassMutual
Flex-Annuity contract, we will base your contingent deterred sales charges on
the issue date of the Flex-Annuity contract.

The exchange programs may not be available in all states. Check with your agent.
We have the right to terminate these exchange programs at any time. If you want
more information about the exchange programs, contact your agent or us at the
Annuity Service Center.

Free Withdrawals

We will not deduct a contingent deferred sales charge on an amount up to 10% of
your contract value:

o     on your first withdrawal in each contract year, and

o     on the maturity date, if you have not made any withdrawals during that
      contract year.

You may not carry over any unused portion of this 10% free withdrawal to any
later withdrawal or maturity date in that contract year.

We have a different free withdrawal provision for contracts purchased by a
Charitable Remainder Trust. Subject to state availability, we will not impose a
contingent deferred sales charge on withdrawals in each contract year equal to
the greater of:

o     10% of the contract value on the date of the first withdrawal in the
      contract year; or

o     earnings in the contract as of the date of the withdrawal.

Premium Taxes

   
Some states and other governmental entities charge premium taxes or similar
taxes. We are responsible for the payment of these taxes and will make a
deduction either from your purchase payments when they are made or from your
contract value when you make withdrawals, when you enter the income phase, or
upon your death, depending on your state of residence. 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 which 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.

The Income Phase

If you want to receive regular income from your annuity, you can choose to
receive fixed and/or variable annuity payments under one of several annuity
options. You can choose the month and year to begin those payments. We call that
date the maturity date.

We ask you to choose your maturity date when you purchase your contract. If you
do not choose an annuity option, we will assume that you selected a variable
monthly annuity under a life income option with 120 payments guaranteed. You can
defer your maturity date to any allowable date later than your current maturity
date, provided we receive the written request 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 30 days before the earlier maturity date desired.

The maturity date must be:

   
(1)   the contract anniversary nearest to the annuitant's 85th birthday;
    

(2)   if state law permits, you may defer the maturity date to age 90; or

(3)   in states where available, the maturity date may be deferred to age 100 on
      contracts purchased by a Charitable Remainder Trust. 

At the maturity date, you have the same fund choices that you had during the
accumulation phase. You can choose whether payments will be fixed, variable, or
a combination of both. You may also elect to receive your contract value in a
lump sum.

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 .

Fixed Annuity Payments

If you choose fixed payments, the payment amount will not vary. The payment
amount will depend upon the following 5 things:

o     the value of your contract on the maturity date;

o     the deduction of premium taxes, if applicable;

o     the deduction of a contingent deferred sales charge, if applicable;

o     the annuity option you select; and

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

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: 

o     the value of your contract on the maturity date;

o     the deduction of premium taxes, if applicable;

o     the deduction of a contingent deferred sales charge, if applicable; and

o     the annuity option you select;

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

o     an assumed investment rate (AIR) of 4%.

Future variable payments will depend on the performance of the funds you
selected. If the actual performance exceeds the 4% assumed 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.


                                                                              23
<PAGE>
 
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
cannot change the annuity option or the frequency of annuity payments. Also, you
may not transfer among the funds and the GPA. In addition, during the income
phase we do not allow withdrawals, except as explained under the fixed time
payment option.

Fixed Income Payment Option. (available as a fixed payment only) 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. The last payment will
be for the remaining balance.

Fixed Time Payment Option. We will make fixed and/or variable monthly annuity
payments for any period selected, up to 30 years. You may elect to withdraw the
present value of the remaining unpaid monthly annuity payments, subject to any
applicable contingent deferred sales charge.

Lifetime Payment Option. We will make fixed and/or variable payments based on
the life of the annuitant. If you elect this option, we will make annuity
payment:

(1)   without any guaranteed number of payments;

(2)   with payments guaranteed for the amount applied; or

(3)   with a guaranteed number of payments for 5, 10 or 20 years.

Interest Payment Option. (available only on non-qualified contracts and
available only as a fixed 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.

Joint Lifetime Payment Option. We will make fixed and/or variable annuity
payments, based on the lives of two annuitants. When one dies, payments continue
for the lifetime of the other. The two variations of this option are:

(1)   Payments for two lives only. No specific number of payments is guaranteed.
      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 and/or
variable monthly payments based on the lives of two annuitants. Payments will
continue while both are living. When one dies, reduced payments will continue
for the lifetime of the other. These reduced payments will be two-thirds of what
we would have paid if both persons had continued to live. Payments stop when
both persons have died.

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 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 do one of two things depending upon what the annuitant elected
at the maturity date: 

o     We will continue making the guaranteed payments to the designated
      beneficiary, or

o     We will make a payment in one sum.

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 which you may elect.


24
<PAGE>
 
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.

We will deduct the amount of any applicable premium taxes, and the amount of any
outstanding contract debt if the contract is a TSA.

We may pay the death benefit in one sum within 7 days after we receive 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 do not impose a contingent deferred sales charge on death benefit
payments.


                                                                              25

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 deferral 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: deductible and non-deductible
Individual Retirement Annuities (IRAs) and pension and profit-sharing plans,
which include 401(k) plans, H.R. 10 Plans, TSAs, etc.

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 the taxpayer reaches age 59 1/2 ;

(2)   paid to your beneficiary after you die;

(3)   paid if the taxpayer becomes 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


26
<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: 

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

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

o     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); 

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

o     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;

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

o     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);

o     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

o     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:

o     reaches age 59 1/2;

o     leaves his/her job;

o     dies;

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

o     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
    


                                                                              27
<PAGE>
 
paid to a spouse as a result of a qualified domestic relations order are not
subject to these restrictions.

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:

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

o     retire;

o     die; or

o     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
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, April 27, 1987, 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
    


28
<PAGE>
 
   
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 re-invested. Therefore the effective yield is slightly higher
than the yield because of the compounding effect.
    

Related Performance

   
Some of the funds available to you may be similar to mutual funds offered in the
retail marketplace. These funds generally have the same investment objectives,
policies and portfolio managers as the retail mutual funds and usually were
formed after the retail mutual funds. While these funds generally have identical
investment objectives, policies and portfolio managers, they are separate and
distinct from retail mutual funds. In fact, performance of these funds may be
dramatically different from the performance of the retail mutual funds. This is
due to differences in the funds' sizes, dates shares of stocks are purchased and
sold, cash flows and expenses. You should remember that retail mutual fund
performance is not the performance of the funds available in this contract and
is not an indication of future performance of these funds.
    

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.
    

Distributors

MML Distributors, LLC (MML Distributors) serves as principal underwriter for the
contracts. MML Investors Service, Inc. (MMLISI) serves as co-underwriter for the
contracts. Their purpose as underwriters is to distribute the contracts.

MML Distributors and MMLISI are wholly-owned subsidiaries of MassMutual. Both
are located at 1414 Main Street, Springfield, Massachusetts 01144-1013

We will pay commissions to our agents who sell the contracts. Currently, we pay
an amount up to 4% of purchase payments.

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


                                                                              29
<PAGE>
 
based on our liability for future variable monthly annuity payments.

Reservation Of Rights

We reserve the right to:

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

o     Add separate account divisions.

o     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, if 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:

o     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

o     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

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

We have reserved the right to defer payment for a withdrawal from the GPA for
the period permitted by law but not for more than six months.

Legal Proceedings

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

Financial Statements

We have included our financial statements and those of the Separate Accounts in
the Statement of Additional Information.

                               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. MassMutual is licensed to transact a life, accident and health
insurance business in all fifty 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 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 Extra 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 MassMutual receives at its Home Office a true
copy thereof. 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 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


                                       2
<PAGE>
 
      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, 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. Non-ERISA TSA values
      may be pledged, however, as collateral for contract loans; and

      (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 or other
      written instrument incident to a divorce.

Assignments may be subject to federal income tax.

                           RESTRICTIONS ON REDEMPTION

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

                      SERVICE ARRANGEMENTS AND DISTRIBUTION

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

MML Distributors may enter into selling agreements with other broker-dealers
which are registered with the SEC as broker-dealers under the Securities
Exchange Act of 1934 and are members of the National Association of Securities
Dealers, Inc. ("selling brokers"). The contracts are sold through agents who are
licensed by state insurance department officials to sell the contracts. These
agents are also registered representatives of selling brokers or MMLISI. The
contracts are offered in all states and the District of Columbia.

   
Pursuant to the Underwriting and Servicing Agreement, both MML Distributors and
MMLISI will receive compensation for their activities as underwriters for each
Separate Account. Compensation paid to MMLISI in 1998 was $350,000. Compensation
paid to MML Distributors in 1998 was $10,000. Commissions will be paid through
MMLISI and MML Distributors to agents and selling brokers for selling the
contracts. During 1998, 1997, and 1996, commission payments amounted to
$37,183,157, $38,134,964, and $35,521,258 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


                                       3
<PAGE>
 
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 contracts described in
the Prospectus.

These Servicing and Administration Agreements may be terminated by the parties
without the payment of any penalty upon sixty 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. Contract owners will not receive
notice with respect to changes in the agreements.

The offering of the contracts is continuous.

                      PURCHASE OF SECURITIES BEING OFFERED

   
Interests in the Separate Account are sold to contract owners as accumulation
units. Until April 30, 2000, deferred contingent sales charges that may
otherwise have been applicable will be waived upon the surrender of a contract
where the proceeds of such redemption are used to purchase certain new
MassMutual group contracts. Charges applicable to the particular group contract,
including any surrender charges, will continue to apply.
    

             Exchange Program: Flex Extra Variable Annuity Contracts

   
Owners of IRA or non-qualified Flex Extra contracts that are beyond the
contingent deferred sales charge period may exchange such contracts for Panorama
Premier variable annuity contracts issued by MassMutual, subject to state
availability or CM Life Insurance Company, a MassMutual life insurance
subsidiary (the "Exchange Program"). For flexible purchase payment contracts,
the sales charge period ends in the tenth year. For single purchase payment
contracts, it ends in the sixth year. The Exchange Program is only available in
those states that have approved both contracts. The entire contract value of the
Flex Extra contract must be transferred to the Panorama Premier contract. While
there is no upper limit on the amount of the contract value, it must be at least
$5,000 ($2,000 for IRA contracts) on the date the owner signs the Panorama
Premier application.

An exchange may occur if the contract owner has money in the Flex Extra
Guaranteed Principal Account ("GPA") even if the applicable state has not
approved the Fixed Account feature of the Panorama Premier contract. In that
case, the contract owner may transfer value in the GPA to any Panorama Premier
sub-account. While value in Flex Extra's GPA must be transferred to Panorama
Premier's Fixed Account, all other assets may be transferred into the
sub-accounts designated by the owner in the application for the Panorama Premier
variable annuity contract. The transfers shall occur within two business days of
the receipt in good order of the Panorama Premier application and all necessary
paperwork. For purposes of determining the amounts that can subsequently be
transferred from and between accounts, a new contract year will begin upon the
issuance of the Panorama Premier contract.
    

When eligible Flex Extra contracts are exchanged for Panorama Premier contracts,
no contingent deferred sales charge shall apply to initial purchase payments
made pursuant to the exchange, but all subsequent purchase payments shall be
subject to the contingent deferred sales charges.

The company may terminate the Exchange Program at any time at its sole
discretion. For further information about the Exchange Program contact your
registered representative or call MassMutual at (800) 234-5606.

   
As indicated in the Panorama Premier prospectus (Highlights: Free Look), the
Panorama Premier contract can be returned to the Company for any reason within
ten (10) calendar days, or longer in certain circumstances, after its receipt by
the contract owner. If this right is exercised, the contract will be terminated
and treated as if it were never issued. Furthermore, the Flex Extra contract
will be reinstated as if it had never been exchanged for the Panorama Premier
contract.
    

In determining whether an exchange is appropriate, a contract owner should
carefully compare the Flex Extra and Panorama Premier contracts and should
carefully review the prospectuses for both products.

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

   
                             The Accumulation Phase
               Valuation Date, Valuation Time and Valuation Period
    

Each day on which the net asset value of the shares of any of the Funds is
determined is a "Valuation Date." The value of shares of the Funds held in 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 of the Separate Account 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.

                  Purchase of Accumulation Units in a Division
                             of a Separate Account

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

The Accumulation Unit Value is determined as of the Valuation Time. Provided
that the contract application is complete, Accumulation Units are purchased at
their Accumulation Unit Value within two days of the date on which a purchase
payment is received in good order in the mail or by wire transfer at
MassMutual's Annuity Service Center or a designated bank lockbox. If such date
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 an initial 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
application information, for example) the payment amount will be refunded unless
specific consent to retain the payment for a longer period is obtained from the
prospective purchaser.
    

                              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


                                        5
<PAGE>
 
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.

   
See the General Formulas section for the general formulas used to compute the
value of an Accumulation Unit for any Division of a Separate Account, and for a
hypothetical illustration using such formulas.
    

                                    
                                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. A contingent deferred sales charge (as described in the
Prospectus) may be deducted from the Accumulated Value of your contract at
maturity. Fixed or 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 of amounts attributable to
a contract to each Division of a Separate Account is determined by multiplying
the number of Accumulation Units credited to a Division on the maturity date of
the contract by the Accumulation Unit Value of that Division on the payment
calculation date for the first variable monthly 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.


                                        6
<PAGE>
 
                                  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
Committee v. Norris.

                            Assumed Investment Rates

The assumed investment rate for each Separate Account Division will be 4% per
annum unless a lower rate is required by state law. The assumed investment rate
will affect the amount by which variable monthly annuity payments will vary from
month to month. If the actual net investment performance for a Division for the
period between the date any variable monthly 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.

                   Illustration of Computation of Accumulation
                and Annuity Unit Value Using Hypothetical Example

The above computations may be illustrated by the following hypothetical example:
Assume that the net earnings of the Division for the Valuation Period were
$11,760; that the value of net assets at the beginning of the Valuation Period
was $30,000,000; that the asset charge was .00003562 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 1.00035638
(.00039200 plus 1.00000000 minus .00003562). The new Accumulation Unit Value
would be $1.13540449 ($1.13500000 x 1.00035638). At an effective annual rate of
4%, the rate of interest for one day is .00010746, and the new Annuity Unit
Value would be $1.06726557 ($1.06700000 x 1.00035638 divided by 1.00010746).

             Illustration of Computation of Variable Monthly Annuity
               Payments for a Contract Using Hypothetical Example

The above computations may be illustrated by the following hypothetical example:
Assume that 35,000 Accumulation Units in a Division of 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 $1.20050000). 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.

                              PERFORMANCE MEASURES

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

                    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, the administrative charge,
and all other fund, Separate Account and contract level charges, except premium
taxes, if any. The administrative charge will be apportioned among the Divisions
of the Separate Account based upon the percentage of in-force contracts
investing in each of the Divisions.

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.

                           Non-Standard Total Returns

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 (April 27, 1987), 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, 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 (April 27, 1987) which they were not.
Beginning on the contract inception date (April 27, 1987), actual accumulation
unit values are used for the MML Equity, MML Money Market, MML Managed Bond, and
MML Blend Funds. Beginning on September 12, 1994, actual accumulation unit
values are used for the Oppenheimer Aggressive Growth, Oppenheimer Global
Securities, and Oppenheimer Strategic Bond Funds.

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 MML 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, it assumes
the income earned is re-invested. Therefore, the effective yield is slightly
higher than the yield because of the compounding effect.

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

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

Before Administrative Charge Deduction (Separate Accounts 1 and 2)

7-Day Yield:                            3.49%

7-Day Effective Yield:                  3.55%

The performance figures discussed above reflect historical results of the Funds
and are not intended to indicate or to predict future performance.

                               FEDERAL TAX MATTERS

                                     General

Note: The following description is based upon the 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 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 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
    


                                       15
<PAGE>
 
   
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.

                          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 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.
    


                                       17

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.
Norris that optional annuity benefits provided under an employer's deferred
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 501(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.

      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
    


                                       18
<PAGE>
 
   
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 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
    


                                       19
<PAGE>
 
   
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.

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
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
Flex Extra (Qualified) segment 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 companies, provide a
reasonable basis for the opinion expressed above.

Massachusetts Mutual Variable Annuity Separate Account 1 - Flex Extra
(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
      Flex Extra (Qualified) segment (the "Segment").

      On September 13, 1994, MassMutual paid $15,000 to provide the initial
      capital for the Segment's three most recently established divisions: 1,516
      shares were purchased in the management investment company described in
      Note 2 supporting the three Oppenheimer divisions of the Segment.

2.    INVESTMENT OF THE SEGMENT'S ASSETS

      The Flex Extra (Qualified) Segment maintains seven 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, the MML Blend
      Division invests in shares of MML Blend Fund, the Oppenheimer Capital
      Appreciation Division invests in shares of Oppenheimer Aggressive Growth
      Fund, the Oppenheimer Global Securities Division invests in shares of
      Oppenheimer Global Securities Fund and the Oppenheimer Strategic Bond
      Division invests in shares of Oppenheimer Strategic Bond 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 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.

      Oppenheimer Aggressive Growth Fund, Oppenheimer Global Securities Fund and
      Oppenheimer Strategic Bond Fund are part of the Oppenheimer Variable
      Account Funds (the "Oppenheimer Trust"). The Oppenheimer Trust is a
      diversified, open-end management investment company registered under the
      Investment Company Act of 1940, for which OppenheimerFunds, Inc. ("OFI"),
      a controlled subsidiary of MassMutual, serves as investment manager.

      In addition to the seven divisions of the Segment, a Contract Owner may
      also allocate funds to the Guaranteed Principal Account, which is part of
      MassMutual's general account. Because of exemptive and exclusionary
      provisions, interests in the Guaranteed Principal Account, which is part
      of MassMutual's general account, are not registered under the Securities
      Act of 1933. Also, the general account is not registered as an investment
      company under the Investment Company Act of 1940.

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.


                                       F-6
<PAGE>
 
Notes To Financial Statements (Continued)

      A. Investment Valuation

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

      B. Accounting for Investments

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

      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 (the "Contracts"). 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 Segment. Net transfers
      from MassMutual to the Segment totaled $218,271 and $314,296 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 AND ADMINISTRATIVE EXPENSES

      Daily charges are made which are currently equivalent on an annual basis
      to 1.30% of the net asset value of the Segment (the "Net Asset Value").
      The mortality and expense risk part of this charge is made daily at an
      annual rate which is currently equal to 1.15%, and will not exceed 1.25%

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 Extra (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 companies, provide a
reasonable basis for the opinion expressed above.

Massachusetts Mutual Variable Annuity Separate Account 2 - Flex Extra
(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 Extra (Non-Qualified)
      segment, (the "Segment").

      On September 13, 1994, MassMutual paid $15,000 to provide the initial
      capital for the Segment's three most recently established divisions: 1,516
      shares were purchased in the management investment company described in
      Note 2 supporting the three Oppenheimer divisions of the Segment.

2.    INVESTMENT OF THE SEGMENT'S ASSETS

      The Flex Extra (Non-Qualified) Segment maintains seven 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, the MML Blend
      Division invests in shares of MML Blend Fund, the Oppenheimer Capital
      Appreciation Division invests in shares of Oppenheimer Aggressive Growth
      Fund, the Oppenheimer Global Securities Division invests in shares of
      Oppenheimer Global Securities Fund and the Oppenheimer Strategic Bond
      Division invests in shares of Oppenheimer Strategic Bond 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 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.

      Oppenheimer Aggressive Growth Fund, Oppenheimer Global Securities Fund and
      Oppenheimer Strategic Bond Fund are part of the Oppenheimer Variable
      Account Funds (the "Oppenheimer Trust"). The Oppenheimer Trust is an
      open-end, diversified, management investment company, registered under the
      Investment Company Act of 1940, for which OppenheimerFunds, Inc. ("OFI"),
      a controlled subsidiary of MassMutual, serves as investment manager.

      In addition to the seven divisions of the Segment, a contractowner may
      also allocate funds to the Guaranteed Principal Account, which is part of
      MassMutual's general account. Because of exemptive and exclusionary
      provisions, interests in the Guaranteed Principal Account, which is part
      of MassMutual's general account, are not registered under the Securities
      Act of 1933. Also, the general account is not registered as an investment
      company under the Investment Company Act of 1940.

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.


                                      F-6

Notes To Financial Statements (Continued)

A.    Investment Valuation

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

B.    Accounting for Investments

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

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 (the "Contracts"). 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 Segment. Net transfers
      from MassMutual to the Segment totaled $227,563 and $96,577 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 AND ADMINISTRATIVE EXPENSES

      Daily charges are made which are currently equivalent on an annual basis
      to 1.30% of the net asset value of the Segment (the "Net Asset Value").
      The mortality and expense risk part of this charge is made daily at an
      annual rate which is currently equal to 1.15%, and will not exceed 1.25%
      of the Net Asset Value. The administrative expense part of this charge is
      made daily at an annual rate of 0.15% of the Net Asset Value.

5.    DISTRIBUTION AGREEMENT

      MML Distributors, LLC ("MML Distributors"), a wholly-owned subsidiary of
      MassMutual, serves as principal underwriter of the contracts pursuant to
      an underwriting and servicing agreement among MML Distributors, MassMutual
      and Separate Account 2. MML Distributors is registered with the Securities
      and Exchange Commission (the "SEC") as a broker-dealer under the
      Securities Exchange Act of 1934 and is a member of the National
      Association of Securities Dealers, Inc. (the "NASD"). MML Distributors may
      enter into selling agreements with other broker-dealers who are registered
      with the SEC and are members of the NASD in order to sell the contracts.

      MML Investors Services, Inc. ("MMLISI") a wholly-owned subsidiary of
      MassMutual, serves as co-underwriter of the contracts pursuant to
      underwriting and servicing agreements among MMLISI, MassMutual and
      Separate Account 2. MMLISI is registered with the SEC as a broker-dealer
      under the Securities Exchange Act of 1934 and is a member of the NASD.
      Registered representatives of MMLISI sell the contracts as authorized
      variable life insurance agents under applicable state insurance laws.

      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 MML Distributors or MMLISI.
      MML Distributors and MMLISI also receive compensation for their activities
      as underwriters 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.

Notes To Statutory Financial Statements (Continued)

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

accumulated benefit obligations.

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.

<PAGE>
 
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.

Notes To Statutory Financial Statements (Continued)


   The carrying value and estimated fair value of bonds at December 31, 1998 by
   contractual maturity are shown below. Expected maturities will differ from
   contractual maturities because borrowers may have the right to call or prepay
   obligations with or without prepayment penalties.


                                                                     Estimated

      TOTAL                                        $25,215.8         $26,696.9
                                                   =========         =========


   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

   Other Subsidiaries:

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

    and affiliated companies as of December 31, 1998 is illustrated below. The

Item 28.    Indemnification


                                       17
<PAGE>
 
            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. 14 to Registration Statement
    No. 33-7724 filed on Form N-4     

Ladies and Gentlemen:

    
This opinion is furnished in connection with the filing of Post-Effective
Amendment No. 14 to Registration Statement No. 33-7724 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 1 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:     

1. 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 1 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
