This prospectus describes group annuity contracts ("Contracts") offered by UNUM
Life Insurance Company of America ("UNUM/America"), a subsidiary of UNUM Hold-
ing Company and its wholly-owned parent company, UNUM Corporation. The Con-
tracts are designed to enable Participants and Employers to accumulate funds
for retirement programs meeting the requirements of the following Sections of
the Internal Revenue Code of 1986, as amended (the "Code"): 401(a), 403(b), 408
and 457 and other related Sections as well as for programs offering non-quali-
fied annuities. A Participant is an employee or other person affiliated with
the Contractholder on whose behalf a Participant Account is maintained under
the terms of the Contract.
   
The Contracts permit Contributions to be deposited in the Guaranteed Interest
Division, which is part of UNUM/ America's General Account, and in certain Sub-
Accounts in UNUM/America's VA-I Separate Account ("Variable Investment Divi-
sion"). Contributions to the Guaranteed Interest Division earn interest at a
guaranteed rate declared by UNUM/America. Contributions to the Variable Invest-
ment Division will increase or decrease in dollar value depending on the in-
vestment performance of the underlying funds in which the Sub-Accounts invest.
Special limits apply to withdrawals and transfers from the Guaranteed Interest
Division.     
 
Currently, the Variable Investment Division consists of the nine Sub-Accounts
listed below: Next to each listed Sub-Account is the name of the fund (the
"Fund") in which the Sub-Account invests. For more information about the in-
vestment objectives, policies and risks of the Funds please refer to the pro-
spectus for each of the Funds.

                     UNUM LIFE INSURANCE COMPANY OF AMERICA
   
  UNUM/America is a life insurance company founded in Maine in 1966.
UNUM/America is a subsidiary of UNUM Holding Company and its wholly-owned
parent company, UNUM Corporation whose stock is traded on the New York Stock
Exchange.     
 
                                  LINCOLN LIFE
   
  On October 1, 1996 (the "Closing Date"), UNUM/America completed the sale of
its tax-sheltered annuity business to The Lincoln National Life Insurance
Company ("Lincoln Life"), pursuant to an acquisition agreement with Lincoln
Life (the "Acquisition Agreement"). Under the Acquisition Agreement, Lincoln
Life assumed UNUM/America's obligations under the Contracts and Lincoln Life &
Annuity Company of New York ("Lincoln-NY") assumed UNUM/America's obligations
under Contracts originally issued in New York by UNUM Life Insurance Company
(the "New York Contracts") other than those obligations to Contractholders
and/or Participants who neither consented nor were deemed to have consented to
the assumption.     
   
  Lincoln Life is a subsidiary of LNC, which is a publicly-owned company whose
stock is traded on the New York Stock Exchange. See "Acquisition Agreement with
The Lincoln National Life Insurance Company."     
 
                               CONTRACTS OFFERED
   
  The Group Variable Annuity Contracts offered by this prospectus were made
available to Employers and other entities to provide a way to accumulate funds
for retirement and to provide Payout Annuities.     
 
                           HOW CONTRIBUTIONS ARE MADE
 
  Contributions under the Contract are deposited by the Contractholder.
Depending upon the type of Plan offered, Contributions may consist of salary
reduction Contributions, Employer Contributions or Participant post-tax
Contributions. Contributions are forwarded by the Contractholder to
UNUM/America and allocated among the two Divisions in accordance with
information provided by the Contractholder. See "Contract Provisions,
Contributions under the Contract".
 
                               DIVISIONS OFFERED
 
  Contributions may be allocated to the Guaranteed Interest Division or to the
Variable Investment Division or to both Divisions. The Variable Investment
Division currently consists of nine Sub-Accounts. A Contractholder may choose
to offer between zero and nine of the Sub-Accounts to its Participants under a
Contract. The Sub-Accounts invest their assets in shares of a corresponding
Fund. For a full description of the Funds, see the prospectuses for the Funds.
 
                  TRANSFERS BETWEEN DIVISIONS AND SUB-ACCOUNTS
 
  During the Accumulation Period, a Participant or a Contractholder under
certain Plans may make transfers between and among Divisions and Sub-Accounts.
Certain Plans may limit the transfers in dollar amount, type of Contribution,
or frequency. Certain Plans may require Contractholder approval for a transfer.
See "Transfers between Divisions and Sub-Accounts".

                                  WITHDRAWALS
 
  During the Accumulation Period, a Participant may withdraw any part of their
account balance subject to the restrictions imposed by the Code and regulations
thereof and by the applicable Plan. With respect to Plans subject to Title I of
the Employee Retirement Income Security Act of 1974 (ERISA), the Contractholder
must authorize UNUM/America to process a withdrawal request by a Participant.
Withdrawal requests under Section 457 Plans must also be authorized by the
Contractholder. With respect to withdrawal requests by Participants under Plans
not subject to Title I of ERISA, certain Contracts may require that the
Participants must certify to UNUM/America that an eligible event under the Code
has occurred. Withdrawal requests must be in writing and in a form acceptable
to UNUM/America.
   
  Certain Plans are also subject to distribution requirements under Section
401(a)(9) of the Code including the incidental death benefit requirements of
Section 401(a)(9)(G). Certain transfers from one Qualified Plan contract to
another Qualified Plan contract are not subject to withdrawal restrictions
under the Code. Certain withdrawals are subject to a 10% Federal Excise Tax for
premature distributions. See "Federal Income Tax Considerations."     
   
  Certain types of withdrawals are subject to a contingent deferred sales
charge ("CDSC"). See "Contract Provisions, Deductions and Charges."     
       
                                 DEATH BENEFITS
 
  The Contracts provide for a Death Benefit for a Participant who dies during
the Accumulation Period. See "Contract Provisions, Death Benefits."
 
                                PAYOUT ANNUITIES
 
  As permitted by the applicable Plan, a Participant or a Beneficiary of a
deceased Participant may elect to convert all or part of the Participant's
Account balance or the Death Benefit, as appropriate, to a Payout Annuity.
UNUM/America offers both Guaranteed and Variable Annuities. The range of
annuity options available include life annuities and annuities for a specific
time period as well as others described more fully in this prospectus. See
"Annuity Period."
 
                              FREE-LOOK PROVISION
 
  A Participant under a Section 403(b) or 408 Plan and certain Non-Qualified
Plans has ten days, in most cases, from the date the Participant receives an
Active Life Certificate to notify UNUM/America in writing that the Participant
does not choose to participate under the Contract and to receive a return of
funds. See "Free-Look Period."
 
                                   FEE TABLE
   
  The following table and examples, prescribed by the SEC, are included to
assist Contractholders and Participants in understanding the transaction and
operating expenses imposed directly or indirectly under the Contracts. The
standardized tables and examples assume the highest deductions possible under
the Contracts, whether or not such deductions actually would be made from a
Participant's Account. A CDSC is deducted from a Participant's Account balance
only if a total or partial withdrawal is made, and then only if one of the
exceptions does not apply.

  The effect of the Annual Administration Charge for a period is determined by
dividing the total amount of such charges collected in the previous year by the
total average net assets of the
 
                                       8
<PAGE>
 
   
accounts for the previous year, as of the previous month ended; accounts
include accounts available under Variable Annuity II of UNUM/America and under
corresponding accounts of Lincoln Life.     
- --------
/1/Premium taxes are not shown. UNUM/America deducts the amount of premium tax-
   es, if any, when paid. Loans taken by a Participant with respect to the Par-
   ticipant's Account balance in the Guaranteed Interest Division may be sub-
   ject to a charge for establishing the loan.
 
/2/The Employer has the option of paying the Annual Administration Charge on
   behalf of the Participants under a Contract. In such a situation, the pro-
   jected expenses would be lower than those indicated in the examples. This
   charge is not imposed during the Annuity Period. In certain situations the
   Annual Administration Charge may be reduced or eliminated. See "Deductions &
   Charges--Annual Administration Charge."
          
/3/Until complete order instructions are received, initial Contributions may be
   allocated temporarily to Fidelity's Variable Insurance Products Fund: Money
   Market Portfolio. Management fees for this fund are 0.21%. Other expenses
   are 0.10%. Total Fund Expenses are 0.31%. See "Initial Contributions."     
   
/4/A portion of the brokerage commissions that certain funds pay was used to
   reduce fund expenses. In addition, certain funds have entered into arrange-
   ments with their custodian whereby credits realized as a result of
   uninvested cash balances were used to reduce custodian expenses. Including
   these reductions, the total operating expenses presented in the table would
   have been 0.57% for VIP Equity-Income Portfolio, 0.67% for VIP Growth Port-
   folio, and 0.64% for VIP II Asset Manager Portfolio.     
   
/5/The figures above are based on expenses for fiscal year 1997, and have been
   restated to reflect an increase in transfer agency expenses of 0.01% ex-
   pected to be incurred in 1998. "Management Fees" includes a performance ad-
   justment which, depending on performance, would cause the fee to be as high
   as 0.85% or as low as 0.55%. "Other Expenses" reflects an indirect fee. Net
   fund operating expenses after reductions for fees paid indirectly (again,
   restated) would be 0.78%.     
   
  The Contracts are designed for retirement planning. Withdrawals prior to
retirement or the Annuity Commencement Date are not consistent with the long-
term purposes of the Contracts and the applicable tax laws. Withdrawals may
also be subject to federal income tax and a 10% Federal tax penalty.     
   
  The fee table and examples reflect expenses and charges of the Sub-Accounts
and the expenses of the applicable Fund for the year ended December 31, 1997.
HOWEVER, THE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR
FUTURE EXPENSES AND CHARGES OF THE SUB-ACCOUNTS OR THE FUNDS. SIMILARLY, THE
ASSUMED 5% ANNUAL RATE OF RETURN IS NOT AN ESTIMATE OR A GUARANTEE OF FUTURE
INVESTMENT PERFORMANCE. See "Deductions and Charges" in this prospectus and the
discussion of Fund Management in the prospectus for each of the Funds for
further information.     
 
                            PERFORMANCE INFORMATION
 
  From time-to-time the Variable Investment Division may advertise or use in
sales literature information concerning the investment performance of the
various Sub-Accounts. No performance presentation should be considered as
representative of future investment results. Actual performance is a function
not only of the investment management of the underlying Funds and market
forces, but of the time and frequency of Contributions, the charges and fees
imposed under the Contract, the fees and expenses of the Funds, and transfers
made by a Participant, among other factors.
  
                                       9
<PAGE>
 
  The investment performance of the Sub-Accounts may be advertised in
comparison with the performances of other variable annuities, other investment
companies (such as mutual funds), and recognized indices (such as the Dow Jones
Industrial Average, Standard & Poor's 500 Composite Stock Price Index, NASDAQ
Index, Consumer Price Index), and data published by Lipper Analytical Services,
Inc., Morningstar, and Variable Annuity Research and Data Service or comparable
services. Performance of the Sub-Accounts may also be compared with performance
of other types of investments. Some advertisements may also include published
editorial comments and performance rankings by independent organizations and
publications that monitor the performance of separate accounts and mutual
funds.
 
  The Sub-Accounts may advertise average annual total return performance
information according to the SEC standardized formula. Average annual total
return shows the average annual percentage increase, or decrease, in the value
of a hypothetical $1,000 contribution allocated to a Sub-Account from the
beginning to the end of each specified period of time. The SEC standardized
formula gives effect to all applicable charges under the Contracts. This method
of calculating performance further assumes that (i) a $1,000 contribution was
allocated to a Sub-Account, (ii) no transfers or additional payments were made
and (iii) the withdrawal of the investment occurs at the end of the period.
Premium taxes are not included in the term "charges" for purposes of this
calculation. The Sub-Accounts may also advertise this total return performance
as described above on a cumulative basis.
   
  The Sub-Accounts may also present non-standard performance information based
on the history of a Fund and adjusted to reflect the fees and charges imposed
under a Contract. The Sub-Accounts may present total return information
computed on a calendar year basis. The Sub-Accounts may also present total
return information over specified periods of time (computed on an average
annual or cumulative basis) either assuming that no CDSC will be deducted or
assuming that no CDSC or administrative charge will be deducted. The Sub-
Accounts may present hypothetical examples that apply the total return to a
hypothetical initial investment. The Sub-Accounts may also present total return
information based on different amounts of periodic investments. For additional
performance information, please refer to the Statement of Additional
Information.     
 
                               PUBLISHED RATINGS
 
  From time to time, in advertisements or in reports to Contractholders,
UNUM/America may reflect endorsements. Endorsements are often in the form of a
list of organizations, individuals or other parties which recommend
UNUM/America or the Contracts. The endorser's name will be used only with the
endorser's consent. It should be noted that the list of endorsements may change
from time to time.
 
  Also, from time to time, the rating of UNUM/America as an insurance company
by A.M. Best may be referred to in advertisements or in reports to
Contractholders. Each year the A.M. Best Company reviews the financial status
of thousands of insurers, culminating in the assignment of Best's Ratings.
These ratings reflect Best's opinion of the relative financial strength and
operating performance of an insurance company in comparison to the norms of the
life/health insurance Industry. Best's ratings range from A++ to F.
 
  In addition, the claims-paying ability of UNUM/America as measured by the
Standard and Poor's Rating Group may be referred to in advertisements or in
reports to Contractholders. A Standard and Poor's insurance claims-paying
ability rating is an assessment of an operating insurance company's financial
capacity to meet the obligations of its insurance policies in accordance with
their terms. Standard and Poor's ratings range from AAA to CCC.
 
  From time to time UNUM/America may refer to Moody's Investors Service rating
of UNUM/America. Moody's Investors Service financial strength ratings indicate
an insurance company's ability to discharge policyholder obligations and claims
and are based on an analysis of the insurance company and its relationship to
its parent, subsidiaries, and affiliates. Moody's Investors Service ratings
range from Aaa to C.

  The financial statements of the Variable Investment Division and of
UNUM/America may be found in the Statement of Additional Information.
 
   UNUM/AMERICA, LINCOLN LIFE, THE VARIABLE INVESTMENT DIVISION AND THE FUNDS
 
                     UNUM LIFE INSURANCE COMPANY OF AMERICA
   
  UNUM/America is a life insurance company originally chartered under Maine law
in 1966 as Unionmutual Stock Life Insurance Company of America. On November 18,
1986, its name was changed it to UNUM Life Insurance Company of America. On
December 31, 1991, was merged with UNUM Life Insurance Company and UNUM Pension
and Insurance Company, with the surviving company being UNUM Life Insurance
Company of America ("UNUM/America"). UNUM/America's principal executive offices
are located at 2211 Congress Street, Portland, Maine 04122. UNUM /America's
telephone number is (207)770-2211. UNUM/America provides a broad line of
disability, health and life insurance products, in addition to group retirement
products. UNUM/America is currently licensed to issue variable contracts in 49
states and the District of Columbia. Administrative services necessary for the
operation of the Variable Investment Division and the Contracts are currently
provided by The Lincoln National Life Insurance Company. See "Deductions and
Charges--Annual Administration Charge."     
   
  UNUM/America is a subsidiary of UNUM Holding Company and its wholly-owned
parent company, UNUM Corporation. UNUM Corporation was organized under Delaware
law on January 11, 1985. UNUM Corporation is a publicly-owned company whose
stock is traded on the New York Stock Exchange.     
 
     ACQUISITION AGREEMENT WITH THE LINCOLN NATIONAL LIFE INSURANCE COMPANY
 
  On October 1, 1996 (the "Closing Date"), UNUM/America completed the sale of
its tax-sheltered annuity business to The Lincoln National Life Insurance
Company ("Lincoln Life"), pursuant to an
 
                                       12
<PAGE>
 
acquisition agreement with Lincoln Life (the "Acquisition Agreement"). Under
the Acquisition Agreement, Lincoln Life assumed UNUM/America's obligations
under the Contracts and Lincoln Life & Annuity Company of New York ("Lincoln-
NY") assumed UNUM/America's obligations under the New York Contracts (other
than those obligations to Contractholders and/or Participants who neither
consented nor were deemed to have consented to the assumption).
 
  Lincoln Life is a stock life insurance company incorporated under the laws of
Indiana on June 12, 1905. Lincoln Life is principally engaged in offering life
insurance policies and annuity policies, and ranks among the largest United
States stock life insurance companies in terms of assets and life insurance in
force. Lincoln Life is also one of the leading life reinsurers in the United
States. Lincoln Life is licensed in all states (except New York) and the
District of Columbia, Guam, and the Virgin Islands.
       
  Lincoln Life is wholly owned by Lincoln National Corporation ("LNC"), a
publicly held insurance holding company incorporated under Indiana Law on
January 5, 1968. The principal office of Lincoln Life is located at 1300 South
Clinton Street, Fort Wayne, Indiana 46801. The principal office of LNC is
located at 200 East Berry Street, Fort Wayne, Indiana 46802. Through
subsidiaries, LNC engages primarily in the issuance of life insurance and
annuities, property-casualty insurance, and other financial services.
   
  UNUM/America and Lincoln Life have notified Contractholders and/or
Participants regarding the assumption of their Contracts (other than New York
Contracts) by Lincoln Life or, in the case of the New York Contracts, by
Lincoln-NY. If the Contractholder opted out of the assumption (or refused to
consent where affirmative consent was required), UNUM/America will remain as
the insurer of the Contract and Participants under that Contract will not be
given the opportunity to have their certificates assumed by Lincoln Life.
Whether or not a Contract was assumed by Lincoln Life, it is administered by
Lincoln Life. If, under a Contract some Participants did opt out and some did
not, the Contract was bifurcated--one Contract has UNUM/America as the insurer
and the other has Lincoln Life as the insurer (or, for the New York Contracts,
Lincoln-NY). Both Contracts, however, are administered by Lincoln Life.     
          
  Currently, the Lincoln Life and Lincoln-NY separate accounts invest in the
underlying Funds that are available through the Sub-Accounts of UNUM/America's
Variable Investment Division, but there can be no assurance that such Funds
will always be made available through the Lincoln Life and Lincoln-NY Separate
Accounts.     
                     
                  LINCOLN FINANCIAL ADVISORS CORPORATION     
   
  Lincoln Financial Advisors Corporation ("LFA"), a registered broker-dealer,
is the principal underwriter of the Contracts. As such, LFA will be offering
the Contracts and performing all duties and functions that are necessary and
proper for distribution of the Contracts. LFA also may enter into sales
agreements with independent broker-dealers for the sale of the Contracts. LFA
may pay sales commissions to broker-dealers up to an amount equivalent to 3.5%
of Contributions under a Contract. LFA's principal business address is 1300
South Clinton Street, Fort Wayne, Indiana 46802. LFA, as a broker-dealer, will
do business in the state of Texas under the name LNC Equity Sales Corporation.
    
       
       
                        THE VARIABLE INVESTMENT DIVISION
 
  On December 31, 1991, pursuant to the merger of UNUM Life Insurance Company
and UNUM Pension and Insurance Company into UNUM/America, the Variable
Investment Division was transferred intact to UNUM/America. Prior to that, on
July 8, 1988, the Board of Directors of UNUM Life Insurance Company authorized
the establishment of the Variable Investment Division called the TSAVA Separate
Account in accordance with the Maine Insurance Code. On February 7, 1991, the
 
                                       13
<PAGE>
 
Board of Directors of UNUM Life Insurance Company expanded the scope of the
Variable Investment Division and changed its name to the VA-I Separate Account.
Under Maine law, the funds in the Variable Investment Division are owned by
UNUM/America and UNUM/America is not, nor can UNUM/America be, a trustee with
respect to those funds. The Variable Investment Division is registered with the
Securities and Exchange Commission ("SEC") as a unit investment trust under the
Investment Company Act of 1940 ("1940 Act"). Registration with the SEC does not
involve supervision of the management or investment practices or policies of
either the Variable Investment Division or UNUM/America by the SEC.
 
  The Variable Investment Division currently consists of nine Sub-Accounts. The
Sub-Accounts invest in shares of the Funds. Therefore, the investment
experience of the Sub-Accounts depends on the performance of the Funds.
 
  The income, gains and losses, realized or unrealized, from assets allocated
to the Variable Investment Division are credited to or charged against the
Variable Investment Division, without regard to other income, gains or losses
in UNUM/America's general account or any other separate account. The Contract
provides that the assets of the Variable Investment Division may not be charged
with liabilities arising out of any other business of UNUM/America.
UNUM/America may accumulate in the Variable Investment Division proceeds from
charges under the Contract and other amounts in excess of the Variable
Investment Division assets representing Contract reserves and liabilities.
UNUM/America is the issuer of the Contracts and the obligations set forth
therein, other than those of the Contractholder or the Participant, are
UNUM/America's. As noted previously, however, UNUM/America has entered into an
agreement providing for the assumption of UNUM/America's obligations under the
New York Contracts (other than the New York Contracts) by Lincoln Life or, in
the case of the New York Contracts, by Lincoln-NY. See "Acquisition Agreement
With The Lincoln National Life Insurance Company."

                                   THE FUNDS
   
  The nine Sub-Accounts invest directly in nine corresponding Funds. Each of
these Funds was formed as an investment vehicle for insurance company separate
accounts. The investment objectives and policies of certain Funds are similar
to the investment objectives and policies of other portfolios that may be
managed by the same investment adviser or manager. The investment results of
the Funds, however, may be higher or lower than the results of such other
portfolios.There can be no assurance, and no representation is made, that the
investment results of any of the Funds will be comparable to the investment
results of any other portfolio, even if the other portfolio has the same
investment adviser or manager.     
 
  Information about each of the Funds, including their investment objectives
and investment management, is contained below. Additional information about the
Funds, their investment policies, risks, fees and expenses and all other
aspects of their operations, can be found in the prospectuses for the Funds,
which should be read carefully before investing. THERE IS NO ASSURANCE THAT ANY
FUND WILL ACHIEVE ITS STATED OBJECTIVE. Additional copies of the Funds'
prospectuses, as well as their Statements of Additional Information, can be
obtained directly from each of the Funds without charge by writing to the
particular Funds at the addresses noted on the front of the Fund prospectus.
Shares of the Funds are sold not only to the Sub-Accounts but also to variable
annuity and variable life separate accounts of other insurance companies. For a
disclosure of possible conflicts involved in the Sub-Accounts investing in
Funds that are so offered, see the applicable Fund prospectus.
 
  On the effective date of a Participant's transfer to Lincoln Life, the
Participant's Account balance in the Variable Investment Division will be
transferred to a Lincoln Life separate account. For Participants under the New
York Contracts, the Account balances will be transferred to a Lincoln-NY
separate account. UNUM/America and Lincoln Life intend that the Lincoln Life
separate account and the Lincoln-NY separate account will each have nine Sub-
Accounts which will invest in the same nine Funds currently offered by
UNUM/America's Variable Investment Division. Any deletion of Funds or
substitution of different Funds would require regulatory approval. Additional
Funds may nevertheless be added or deleted in the future.
   
  All dividend and capital gain distributions of the Funds are automatically
reinvested in shares of the distributing Funds at their net asset value on the
date of distribution.

  UNUM/America has designed these Contracts for Employers and other entities to
enable Participants and Employers to accumulate funds for retirement programs
meeting the requirements of the following Sections of the Internal Revenue Code
of 1986, as amended (the "Code"): 401(a), 403(b), 408, 457 and other related
Sections as well as for programs offering non-qualified annuities. For Plans
that have allocated rights to the Participant, UNUM/America will issue to each
Participant a separate Active Life Certificate that describes the basic
provisions of the Contract to each Participant.     
 
                        CONTRIBUTIONS UNDER THE CONTRACT
   
  Generally, under the Contracts, Contractholders forward Contributions to
UNUM/America for investment. Depending on the Plan, the Contributions may
consist of salary reduction Contributions, Employer Contributions or post-tax
Contributions. Lincoln Life administers the Contracts including, among other
services, processing Contributions (which may be temporarily maintained in
Lincoln Life's general account) and withdrawals.     
 
  Contributions may accumulate on either a guaranteed or variable basis
depending upon the Divisions available under the Contract and/or the Division
in which the Contributions are deposited. Contributions to the Guaranteed
Interest Division become part of UNUM/America's General Account and are
guaranteed a minimum rate of interest.
 
  UNUM/America will also declare in advance a guaranteed interest rate which
will be effective for all amounts in the Participant's Account balance in the
Guaranteed Interest Division during the designated year. This rate will never
be less than the minimum rate of interest. UNUM/America may also declare in
advance separate interest rate guarantees which are in excess of the guaranteed
 
                                       17
<PAGE>
 
interest rate for some or all of the Participant's Account balance in the
Guaranteed Interest Division for specific period(s) during the designated year.
UNUM/America assumes the risk of investment gain or loss on contributions to
the Guaranteed Interest Division. See "Guaranteed Interest Division."
Contributions to the Variable Investment Division are credited with a rate of
return dependent upon the investment experience of the Sub-Accounts in which
the Contributions are invested.
 
  Contributions by Participants may be in any amount unless there is a minimum
amount set by the Contractholder or Plan. A Contract may require the
Contractholder to contribute a minimum annual amount on behalf of all
Participants. Annual Contributions under Qualified Plans may be subject to
maximum limits imposed by the Code. Annual Contributions under non-qualified
plans may be limited by the terms of the Contract. In the Statement of
Additional Information see "Tax Law Considerations" for a discussion of these
limits. Subject to any restrictions imposed by the Plan or the Code, transfers
from other Contracts and qualified rollover Contributions will be accepted.
 
  Section 830.205 of the Texas Education Code provides that Employer or state
Contributions (other than salary reduction Contributions) on behalf of
Participants in the Texas Optional Retirement Program ("ORP") vest after one
year of participation in the program. UNUM/America will return Employer
Contributions to the Contractholder for those employees who terminate
employment in all Texas institutions of higher education before becoming
vested. During this first participation year in the ORP, ORP Participants may
only direct Employer and state Contributions to the Guaranteed Interest
Division.
 
  Contributions must be in United States funds unless UNUM/America agrees in
writing to accept other currencies. Any non-US funds will be converted to U.S.
funds. All withdrawals and distributions under this Contract will be in U.S.
funds. If a bank or other financial institution does not honor the check or
other payment method constituting a Contribution, UNUM/America will treat the
Contribution as invalid. All allocation and subsequent transfers resulting from
the invalid Contributions shall be reversed and the party responsible for the
invalid Contribution shall reimburse UNUM/America for any losses or expenses
resulting from the invalid Contribution.
 
                             INITIAL CONTRIBUTIONS
 
  The initial Contribution for a Participant will be credited to the
Participant's Account no later than two Business Days after it is received by
UNUM/America if it is preceded or accompanied by a completed enrollment form
containing all the information necessary for processing the Participant's
Contribution. If UNUM/America does not receive a complete enrollment form,
UNUM/America will notify the Contractholder or the Participant that
UNUM/America does not have the necessary information to process the
Contribution. If the necessary information is not provided to UNUM/America
within five (5) Business Days after UNUM/America first receives the initial
Contribution, UNUM/America will return the initial Contribution less any
withdrawal(s) by the Participant or by the Contractholder, unless the
Participant or the Contractholder specifically consents to UNUM/America
retaining the Contribution until the enrollment form is made complete.
 
  Notwithstanding the above, when the Contract includes language regarding the
"Pending Allocation Account", the following shall apply: Where state approval
has been obtained, if UNUM/America receives Contributions which are not
accompanied by a properly completed Enrollment Form, UNUM/America will notify
the Contractholder of that fact and deposit the Contributions to the Pending
Allocation Account, unless such Contributions are designated to another Account
in accordance with the Plan. Within two business days of receipt of a properly
completed Enrollment Form, the Participant's Account balance in the Pending
Allocation Account will be transferred in accordance with the allocation
percentages elected on the Enrollment Form. All future Contributions will also
be allocated in accordance with these percentages until such time as the
Participant may notify UNUM/America of a change. If a properly completed
Enrollment Form is not received after three monthly notices have been sent, the
Participant's Account balance in the
 
                                       18
<PAGE>
 
Pending Allocation Account will be refunded to the Contractholder within 105
days of the date of the initial Contribution. The Pending Allocation Account
invests in Fidelity's Variable Insurance Products Fund: Money Market Portfolio
and is not available as an investment option under the group annuity contract.
Mortality & Expense Risk Charges and the Annual Administration Charge do not
apply to this Account. These charges will be applicable upon receipt of a
properly completed Enrollment Form and the Participant's Contract Participation
Date will be the date money was deposited in the Pending Allocation Account.
 
                          ALLOCATION OF CONTRIBUTIONS
 
  A Participant must designate in writing, subject to the Plan, the percent of
their Contribution which will be allocated to each Division and to each Sub-
Account available under their Contract. The Contributions allocation percentage
to the Guaranteed Investment Division or any Sub-Account can be in any whole
percent. A Participant whose Employer offers two or more UNUM/America Contracts
for the same type of Qualified or Non-Qualified Plans may allocate
Contributions to a maximum of ten Sub-Accounts and THE Guaranteed Interest
Division. Participants, subject to the terms of the Plan, may change the
allocation of Contributions by notifying UNUM/America in writing or by
telephone in accordance with procedures published by UNUM/America. Telephone
requests for allocation changes follow the same verification of identity rules
as for Transfers. (See "Telephone Transfers.") When UNUM/America receives a
notice in writing, the form must be acceptable to UNUM/America. Upon receipt by
UNUM/America, the change will be effective for all Contributions received
concurrently with the allocation change form and for all future Contributions,
unless a later date is requested. Changes in the allocation of future
Contributions have no effect on amounts a Participant may have already
contributed. Such amounts, however, may be transferred between Divisions and
Sub-Accounts pursuant to the requirements described in "Transfers between
Divisions and Sub-Accounts." Allocations of employer contributions may be
restricted by the applicable plan.
 
                            SUBSEQUENT CONTRIBUTIONS
 
  The Contractholder will forward Contributions to UNUM/America specifying the
amount being contributed on behalf of each Participant. The Contractholder must
send Contributions and provide such allocation information in accordance with
procedures established by UNUM/America. The Contributions shall be allocated
among the Guaranteed Interest Division and the Variable Investment Division in
accordance with the Contractholder's or the Participant's written instructions
as described above in "Allocation of Contributions."
 
                          INVESTMENT OF CONTRIBUTIONS
 
  Contributions are invested as of the date of receipt at UNUM/America,
provided that they are received on a Business Day and allocation information is
provided in a form acceptable to UNUM/America in accordance with procedures
established by UNUM/America. Contributions on behalf of a Participant which are
allocated to the Variable Investment Division will be credited with
Accumulation Units as of that date. A Participant's interest in the Variable
Investment Division during the Accumulation Period is the value of the
Participant's Accumulation Units in the Variable Investment Division. Upon
payment of a Contribution, the number of Accumulation Units credited to a
Participant's Account in a Sub-Account is calculated by dividing the
Contribution allocated to the Sub-Account by the dollar value of an
Accumulation Unit next determined after receipt of the Contribution. The number
of Accumulation Units purchased will not vary as a result of any subsequent
fluctuations in the Accumulation Unit Value. The Accumulation Unit Value, of
course, fluctuates with the investment performance of the underlying Fund and
also reflects deductions and charges made against the Variable Investment
Division.
 
                                       19
<PAGE>
 
                   DETERMINATION OF ACCUMULATION UNIT VALUE
          
  Contributions allocated to the Variable Investment Division are converted
into Accumulation Units. This is done by dividing each Contribution by the
value of an Accumulation Unit for the Valuation Period during which the
Contribution is allocated to the Variable Investment Division. The
Accumulation Unit Value for each Sub-Account was or will be established at the
inception of the Sub-Account. It may increase or decrease from Valuation
Period to Valuation Period. The Accumulation Unit Value for a Sub-Account for
a later Valuation Period is determined as follows:     
     
    (a) The total value of Fund shares held in the Sub-Account is calculated
  by multiplying the number of shares by the net asset value at end of the
  Valuation Period, and adding any dividend or other distribution of the Fund
  if an ex-dividend date occurs during the Valuation Period; minus     
     
    (b) The liabilities of the Sub-Account at the end of the Valuation Peri-
  od; these liabilities include daily charges imposed on the Sub-Account, and
  may include a charge or credit with respect to any taxes paid or reserved
  for by UNUM/America that it determines result from the operations of the
  Variable Investment Division; and     
     
    (c) The result of (b) is divided by the number of Accumulation Units out-
  standing at the beginning of the Valuation Period.     
   
The daily charges imposed on a Sub-Account for any Valuation Period are equal
to the mortality and expense risk charge for the number of calendar days in
the Valuation Period.     
 
  The Participant's Account balance is equal to the sum of the Participant's
Account balances in both the Variable Investment Division and the Guaranteed
Interest Division.
 
                 TRANSFERS BETWEEN DIVISIONS AND SUB-ACCOUNTS
 
  During the Accumulation Period and subject to the terms of the Plan,
transfers may be made of all or part of a Participant's Account balance in any
Division or Sub-Account to another Sub-Account or Division. Transfers will not
change the allocation of future Contributions to the Divisions and Sub-
Accounts. UNUM/America does not require that any minimum amount be
transferred. To effect a transfer, UNUM/America must receive a written
transfer request in a form acceptable to UNUM/America.
 
  Transfers to or from the Variable Investment Division are made using the
Accumulation Unit Value next computed following UNUM/America's receipt of the
written transfer request.
 
            TELEPHONE TRANSFERS BETWEEN DIVISIONS AND SUB-ACCOUNTS
 
  UNUM/America may accept telephone transfers from Participants when this is
allowed by the Contractholder. In order to prevent unauthorized or fraudulent
transfers, UNUM/America will require a Participant to provide certain
identifying information before UNUM/America will act upon their instructions.
UNUM/America may also assign the Participant a Personal Identification Number
(PIN) to serve as identification. UNUM/America will not be liable for
following telephone instructions it reasonably believes are genuine. Telephone
transfer requests may be recorded and written confirmation of all transfer
requests will be mailed to the Participant or Contractholder on the next
Business Day. Telephone transfers will be processed on the Business Day that
they are received when they are received at the UNUM/America Home Office
before 4:00 P.M. ET. If the Participant or Contractholder determines that a
transfer has been made in error, the Participant or Contractholder must notify
UNUM/America within 30 days of the confirmation notice date. See "Contract
Provisions, Transfers between Divisions and Sub-Accounts."

                                  WITHDRAWALS
 
  During the Accumulation Period and subject to the terms of the Plan,
withdrawals may be made from either or both Divisions of all or part of the
Participant's Account balance in a Division or Sub-Account remaining after
deductions for any applicable (1) CDSC; (2) Annual Administration Charge
(imposed on Total Withdrawals), (3) premium taxes, and (4) outstanding loan
including loan security. Annuity Conversion Amounts are not considered
withdrawals. See "Annuity Period, Annuities: General."
 
  All withdrawal requests must indicate the amount to be withdrawn and be
submitted in a form acceptable to UNUM/America. If the request does not specify
the Sub-Accounts and/or the Divisions from which the withdrawal is to be made,
the withdrawal will be made pro rata based on balances in the Sub-Accounts and
the Guaranteed Interest Division. UNUM/America does not require that any
minimum amount be withdrawn. Telephone withdrawal requests are not available.
 
  Withdrawals from the Variable Investment Division are made by reducing the
Participant's number of Accumulation Units in the applicable Sub-Account. In
determining the number of Accumulation Units to be reduced, UNUM/America uses
the Accumulation Unit Value next computed after UNUM/America's receipt of the
written withdrawal request.
 
  Payment of all Variable Investment Division withdrawal amounts will be made,
within the time period allowed under current Federal law but in no case later
than seven days, after receipt by UNUM/America of the withdrawal request in a
form acceptable to UNUM/America. See "Market Emergencies."
 
                               TOTAL WITHDRAWALS
 
  A Total Withdrawal can only be made by a Participant who has no outstanding
loans under the Contract. A Total Withdrawal of a Participant's Account will
occur when (a) the Participant or Contractholder requests the liquidation of
the Participant's entire Account balance, or (b) the amount requested plus any
CDSC results in a remaining Participant's Account balance of less than or equal
to the Annual Administration Charge, in which case the request is treated as if
it were a request for liquidation of the Participant's entire account balance.
 
  Any Active Life Certificate must be surrendered to UNUM/America when a Total
Withdrawal occurs. If a Contractholder resumes Contributions on behalf of a
Participant after a Total Withdrawal, the Participant will receive a new
Participation Date and Active Life Certificate.
 
  A Participant refund under the free-look provisions is not considered a Total
Withdrawal.
 
                              PARTIAL WITHDRAWALS
 
  A Partial Withdrawal of a Participant's Account will occur when less than a
Total Withdrawal is made from a Participant's Account.
 
                          SYSTEMATIC WITHDRAWAL OPTION
 
  Participants who are at least age 59 1/2, are separated from service from
their employer, or are disabled, and certain spousal beneficiaries and
alternate payees who are former spouses, may be eligible for a Systematic
Withdrawal Option ("SWO") under the Contract. Under the SWO a Participant may
elect to withdraw either a monthly amount which is an approximation of the
interest earned between each payment period based upon the interest rate in
effect at the beginning of each respective payment period, or a flat dollar
amount withdrawn on a periodic basis. Payments are made only from the
Guaranteed Interest Account. A Participant must have a vested pre-tax account
 
                                       21
<PAGE>
 
balance of at least $10,000 in order to select the SWO. A Participant may
transfer amounts from the Variable Investment Division to the Guaranteed
Interest Division in order to support SWO payments. These transfers, however,
are subject to the transfer restrictions described in this Prospectus and/or
imposed by any applicable Plan. A one-time fee of up to $30 may be charged to
set up the SWO. This charge is waived for total vested pre-tax account balances
of $25,000 or more. More information about SWO, including applicable fees and
charges, is available in the Contracts and Active Life Certificates as well as
from UNUM/America.
 
                          MAXIMUM CONSERVATION OPTION
 
  Under certain Contracts participants who are at least age 70 1/2 may request
that UNUM/America calculate and pay to them the minimum annual distribution
required by Sections 401(a)(9), 403(b)(10), 408(a) or 457(d) of the Code. The
Participant must complete forms as required by UNUM/America in order to elect
this option. UNUM/America will base its calculation solely on the Participant's
Account Value with UNUM/America. Participants who select this option are
responsible for determining the minimum distributions amount applicable to
their non-UNUM/America Contracts.
 
                            WITHDRAWAL RESTRICTIONS
 
  Withdrawals under Section 403(b) Contracts are subject to the limitations
under Section 403(b)(11) of the Code and regulations thereof and in any
applicable Plan document. That section provides that salary reduction
Contributions deposited and earnings credited on any salary reduction
Contributions after December 31, 1988 may only be withdrawn if the Participant
has (1) died; (2) become disabled; (3) attained age 59 1/2; (4) separated from
service; or (5) incurred a hardship. Amounts accumulated in one Section
403(b)(1) contract may be transferred to another Section 403(b)(1) contract or
Section 403(b)(7) custodial account without a penalty under the Code. If
amounts accumulated in a Section 403(b)(7) custodial account are deposited in a
Contract, such amounts will be subject to the same withdrawal restrictions as
are applicable to post-1988 salary reduction Contributions under the Contracts.
For more information on these provisions see "Federal Income Tax
Considerations."
 
  Withdrawal requests for a Participant under Section 457(b) Plans and Plans
subject to Title I of ERISA must be authorized by the Contractholder on behalf
of a Participant. All withdrawal requests will require the Contractholder's
written authorization and written documentation specifying the portion of the
Participant's Account balance which is available for distribution to the
Participant. Withdrawal requests for Section 457(f) Plans must be requested by
the Contractholder.
 
  As required by Section 830.105 of the Texas Education Code, withdrawal
requests by Participants in the Texas Optional Retirement Program ("ORP") are
only permitted in the event of (1) death; (2) retirement; (3) termination of
employment in all Texas institutions of higher education; or (4) attainment of
age 70 1/2. A Participant in an ORP Contract is required to obtain a
certificate of termination from the Participant's Employer before a withdrawal
request can be granted.
 
  For withdrawal requests (other than transfers to other investment vehicles),
by Participants under Plans not subject to Title I of ERISA and non-457 Plans,
the Participant must certify to UNUM/America that one of the events listed in
the Code has occurred (and provide supporting information, if requested) and
that UNUM/America may rely on such representation in granting such withdrawal
request. See "Federal Income Tax Considerations." A Participant should consult
their tax adviser as well as review the provisions of their Plan before
requesting a withdrawal.
 
  In addition to the restrictions noted above, a Plan may contain additional
withdrawal or transfer restrictions.
 
  Early withdrawals, as defined under Section 72(q) and 72(t) of the Code, may
be subject to a ten percent excise tax.

                                 DEATH BENEFITS
 
  The payment of death benefits will be governed by the provisions of the
applicable Plan and the Code. In the event of the death of a Participant during
the Accumulation Period, UNUM/America will pay the Beneficiary, if one is
living, or the Plan the greater of the following amounts:
 
    (1) The Net Contributions, or
 
    (2) The Participant's Account balance less any outstanding loan (includ-
  ing principal and due and accrued interest), as of the date of notifica-
  tion.
 
  If UNUM/America is not notified of the Participant's death within six months
of such death, the Beneficiary will receive the Death Benefit amount described
in paragraph (2).
 
  A Beneficiary may elect to have the Death Benefit (1) paid as a lump sum, (2)
converted to a Payout Annuity or (3) as a combination of a lump sum payment and
a Payout Annuity.
 
  UNUM/America will calculate the Death Benefit as of the end of the Valuation
Period during which it receives both satisfactory notification of the
Participant's death and an election of a form of Death Benefit (as described
below). Payment of a lump sum election will be made within the time period
prescribed by Federal law but in no case later than seven days following such
calculation. Payment of an annuity option will be paid in accordance with the
provisions regarding annuities. See "Annuity Period." If no election is made
within sixty days following UNUM/America's receipt of satisfactory notice of
the Participant's death, the Death Benefit will be paid in the form of a lump
sum payment and will be calculated as of the end of the Valuation Period during
which that sixtieth day occurs (and payment will be made within the time period
prescribed by Federal law but in no case later than seven days after such
calculation date).
 
  Satisfactory proof of death may consist of: a copy of a certified death
certificate; a copy of a certified decree of a court of competent jurisdiction
as to the finding of death; a written statement by a medical doctor who
attended the deceased at the time of death; or any other proof satisfactory to
UNUM/America.
 
  Notwithstanding the above, if the Beneficiary is someone other than the
spouse of the deceased Participant, the Code provides that the Beneficiary may
not elect an annuity which would commence later than December 31st of the
calendar year following the calendar year of the Participant's death. If a non-
spousal Beneficiary elects to receive payment in a single lump sum, the Code
provides that such payment must be received no later than December 31st of the
fourth calendar year following the calendar year of the Participant's death.
 
  If the Beneficiary is the surviving spouse of the deceased Participant,
distributions are not required under the Code to begin earlier than December
31st of the calendar year in which the Participant would have attained age 70
1/2. If the surviving spouse dies before the date distributions commence, then,
for purposes of determining the date distributions to the Beneficiary must
commence, the date of death of the surviving spouse is substituted for the date
of death of the Participant.
 
  If there is no living named Beneficiary on file with UNUM/America at the time
of a Participant's death and unless the Plan directs otherwise, UNUM/America
will pay the Death Benefit to the Participant's estate in the form of a lump
sum payment, upon receipt of satisfactory proof of the Participant's death, but
only if such proof of death is received by UNUM/America no later than the end
of the fourth calendar year following the year of the Participant's death. In
such case, valuation of the Death Benefit will occur as of the end of the
Valuation Period during which due proof of death is received by UNUM/America,
and the lump sum Death Benefit will be paid within the time period prescribed
by Federal law but in no case later than seven days of that date.

                             DEDUCTIONS AND CHARGES
   
  UNUM/America will deduct the charges described below to cover costs and
expenses, services provided and risks assumed under the Contracts. UNUM/America
incurs certain costs and expenses for the distribution and administration of
the Contracts and for providing the benefits payable thereunder. The amount of
a charge may not necessarily correspond to the costs associated with providing
the services or benefits indicated by the designation of the charge. For
example, the CDSC may not fully cover all of the sales and distribution
expenses actually incurred by UNUM/America, and proceeds from other charges,
including the mortality and expense risk charge, may be used in part to cover
such expenses.     
 
                CHARGES AGAINST THE VARIABLE INVESTMENT DIVISION
 
MORTALITY AND EXPENSE RISK CHARGES
 
  Certain charges will be assessed as a percentage of the value of the net
assets of the Variable Investment Division to compensate UNUM/America for risks
assumed in connection with the Contracts.
 
  UNUM/America deducts from the net assets of the Variable Investment Division
a daily charge of 1.20% on an annual basis.
 
  This charge is assessed both during the Accumulation Period and the Annuity
Period although, during the Annuity Period, UNUM/America will bear no mortality
risk with respect to the Annuity Options that do not involve life
contingencies. This amount is intended to compensate UNUM/America for certain
Mortality and Expense Risks UNUM/America assumes in operating the Variable
Investment Division and for providing services to the Participant. The total
charge may not be altered.
 
  The Expense Risk is the risk that UNUM/America's actual expenses in issuing
and administering the Contract will be more than UNUM/America estimated. The
Mortality Risk borne by UNUM/America arises from the chance that UNUM/America's
actuarial estimate of mortality rates during the Annuity Period, as guaranteed
in the Contract, may prove erroneous and that an Annuitant may live longer than
expected. This contractual guarantee assures that neither an Annuitant's own
longevity nor an improvement in life expectancy generally will have any adverse
effect under the Contracts. In addition, UNUM/America bears the Mortality Risk
that it guarantees to pay a Death Benefit that may be higher than the
Participant's Account balance upon the death of the Participant prior to the
Annuity Period.
 
                         CHARGES AGAINST THE CONTRACTS
 
  The charges that UNUM/America assesses in connection with the Contracts are
described below.
 
ANNUAL ADMINISTRATION CHARGE
 
  UNUM/America provides many administrative functions in connection with the
Contracts, including receiving and allocating Contributions in accordance with
the Contracts, making annuity payments when they become due, and preparing and
filing all reports required to be filed by the Variable Investment Division. In
addition, UNUM/America provides Participants with Account statements and
accounting services that keep track of pre-tax monies, employee and Employer
monies, vested Account balances and rollover or transferred monies.
 
  In consideration for these administrative services, UNUM/America currently
deducts $25 (or the balance of the Participant's Account if less) per year from
each Participant's Account balance on the last Business Day of the month in
which a Participation Anniversary occurs. This charge is deducted only during
the Accumulation Period. This Annual Administration Charge is also withdrawn
from a Participant's Account balance if and when a Participant's Account is
totally withdrawn on any date
 
                                       24
<PAGE>
 
other than the last Business Day of the month in which the Participation
Anniversary occurs. The charge may be increased or decreased (subject to any
appropriate regulatory approvals).
 
  The Annual Administration Charge may be reduced or waived for those
Participants who are participating under another UNUM/America Contract which
imposes an Annual Administration Charge or where UNUM/America's interest costs
or expenses are reduced due to the terms of the Contract, economies of scale or
administrative assistance provided by the Contractholder. In addition, the
Employer has the option of paying the Annual Administration charge on behalf of
the Participants under a Contract.
 
  Under certain Contracts, the Contractholder may also choose to have the
Annual Administration Charge paid only by those Participants in the Variable
Investment Division. Contracts offering this provision will typically have a
declared interest rate in the Guaranteed Interest Division which is lower than
under Contracts not offering this provision. For Contracts offering this
provision, the Annual Administration Charge will be withdrawn as described in
this section.
 
  Since the Closing Date, Lincoln Life has administered the Contracts on behalf
of UNUM/America pursuant to an administrative services agreement. See
"Acquisition Agreement with The Lincoln National Life Insurance Company."
 
PREMIUM TAXES
 
  Certain states require that a premium tax be paid on contributions to a
variable annuity Contract. Others assess a premium tax at the time of
annuitization. UNUM/America will deduct any applicable premium tax from the
Participant's Account balance at the time required by state law.
 
CONTINGENT DEFERRED SALES CHARGE
 
  UNUM/America does not impose a sales charge at the time a Contribution is
made to a Participant's Account under the Contract. During the Accumulation
Period UNUM/America charges a CDSC in the amount of 6% on all Total or Partial
Withdrawals of a Participant's Account balance unless UNUM/America receives, at
the time of the withdrawal request, reasonable proof necessary to verify that:
(a) the Participant has attained age 59 1/2; (b) the Participant has died; (c)
the Participant has incurred a disability as defined under the Contract; or (d)
the Participant has terminated employment with the Employer and is at least 55
years of age.
 
  The CDSC reimburses UNUM/America for part or all of its expenses related to
distributing the Contracts. If the revenues generated by the CDSC are not
sufficient to cover UNUM/America's actual costs of distribution, such costs
will be paid from UNUM/America's General Account assets, which may include any
ultimate profit derived from the mortality and expense risk charge.
 
  Under certain Contracts, the Contractholder may choose to add "financial
hardship" as another event which is not subject to a CDSC. A Contractholder may
also choose to eliminate the requirement that a participant must be at least 55
years of age when he terminates employment. Finally, a Contractholder can add a
provision to their Contract entitling Participants to withdraw, once each
calendar year, up to 20% of their Account balance without the imposition of a
CDSC. These contracts which provide additional benefits to Participants may
receive a declared guaranteed interest rate which is lower than other contracts
not providing these additional benefits.
 
  The CDSC on any withdrawal may be reduced or eliminated but only to the
extent that UNUM/America anticipates that it will incur lower sales expenses or
perform fewer sales services due to economies arising from (a) the size of the
particular group, (b) an existing relationship with the Contractholder or
Employer, (c) the utilization of mass enrollment procedures, or (d) the
performance of sales functions by the Contractholder or an Employer which
UNUM/America would otherwise be required to perform.
 
  The CDSC is imposed on the Gross Withdrawal Amount. A Participant may request
to receive a specific Net Withdrawal Amount. If the Participant requests a
specific Net Withdrawal Amount, the
 
                                       25
<PAGE>
 
CDSC will be imposed on a Gross Withdrawal Amount, which after deducting the
CDSC, gives the Participant the Net Withdrawal Amount requested. The following
example illustrates the formula:
 
  Participant requests a Net Withdrawal Amount of $100 in their tenth
Participation Year. UNUM/America will impose the 6% CDSC on a Gross Withdrawal
Amount of $106.38 and the Participant will receive $100. This is the standard
procedure for withdrawals.
 
  The CDSC will be deducted from the Divisions and Sub-Accounts in proportion
to amounts withdrawn therefrom. Death Benefit payments and amounts converted to
an annuity are not subject to a CDSC. In no event will the CDSC, when added to
any CDSC previously imposed due to a Participant withdrawal, exceed 8.5% of the
cumulative Contributions to a Participant's Account.
 
                                 MISCELLANEOUS
 
  The Variable Investment Division purchases shares from the Funds at net asset
value. The net asset value reflects investment management fees and other
expenses that have already been deducted from the assets of the Funds. The
Funds' investment management fees, expenses and expense limitations, if
applicable, are more fully described in each prospectus for the Funds.
 
                                 ANNUITY PERIOD
 
                           PAYOUT ANNUITIES: GENERAL
   
  To the extent permitted by the Plan, the Participant, or the Beneficiary of a
deceased Participant, may elect to convert all or part of the Participant's
Account balance or the Death Benefit to a Payout Annuity. Payout Annuities are
available as either a Guaranteed or Variable Annuity or a combination of both.
Annuity payments from a Guaranteed Annuity remain constant throughout the
annuity period. Payout Annuities may be maintained in the Variable Investment
Division, or, if the Participant so agrees, in a separate account of Lincoln
Life ("Variable Payout Division"). No charge will be imposed at the time that
the Annuity Conversion Amount is applied to a Variable Payout Division in
implementing any Payout Annuity option. The Contract benefits and charges for a
Payout Annuity, whether maintained in the Variable Investment Division or in a
Variable Payout Division, are as described in this prospectus. The selection of
funds available through a Variable Payout Division may, however, differ from
the selection of Funds available through the Variable Investment Division. If a
Participant's Payout Annuity will be maintained in a Variable Payout Division,
a prospectus for the Variable Payout Division will be provided prior to the
Annuity Commencement Date. Annuity payments from a Variable Annuity fluctuate
depending upon the investment experience of the applicable sub-accounts.
Variable Annuity payments are based upon Annuity Unit Values. See "Annuity
Payments" below and "Determination of Variable Annuity Payments" in the
Statement of Additional Information for more information.     
 
  The Annuity Commencement Date marks the date on which the first annuity
payment is made to an Annuitant. For Plans subject to Section 401(a)(9)(B) of
the Code, a Beneficiary must select an Annuity Commencement Date that is not
later than one year after the date of the Participant's death. A Participant or
Contractholder may select any Annuity Commencement Date for the Annuitant which
is then reflected in the Retired Life Certificate. However, since an annuity
payment is considered a distribution under the Code, selection of an Annuity
Commencement Date may be affected by the distribution restrictions under the
Code and the minimum distribution requirements under Section 401(a)(9) of the
Code. See "Federal Income Tax Considerations." The selection of an Annuity
Commencement Date, the annuity option, the amount of the Payout Annuity and
whether the amount is to be paid as a Guaranteed or a Variable Annuity must be
made by the Participant in writing, in a satisfactory form, and received at
least 30 days in advance of the Annuity Commencement Date. After the Annuity
Commencement Date an Annuitant may not change either the annuity option or the
type (i.e., variable or guaranteed) of Payout Annuity for any amount applied
toward the purchase of an annuity.
 
                                       26
<PAGE>
 
  The Annuity Conversion Amount is either the Participant's Account balance, or
a portion thereof, or the Death Benefit plus interest, as of the Annuity
Payment Calculation Date. For a Guaranteed Annuity, the Annuity Commencement
Date is typically one month after the Annuity Payment Calculation Date;
subsequent payments are at one month intervals from the Annuity Commencement
Date. For a Variable Annuity, the Annuity Commencement Date is 10 Business Days
after the initial Annuity Payment Calculation Date; subsequent monthly payments
have Annuity Payment Calculation Dates which are 10 business days prior. The 10
Business Days are necessary to calculate the amount of the Payout Annuity
payments and to mail the checks in advance of their monthly due dates.
 
  If the Participant's Account balance or the Beneficiary's Death Benefit is
less than $2,000 or if the amount of the first scheduled payment is less than
$20, the annuity may be cancelled and the Participant or Beneficiary required
to accept payment of the entire amount in a lump sum.
 
                            PAYOUT ANNUITY PAYMENTS
 
  The amount of each annuity payment will depend upon the Annuity Conversion
Amount, The annuity option, the age of the Participant(s) on the initial
Annuity Payment Calculation Date, and the length of time from the initial
Annuity Payment Calculation Date to the Annuity Commencement Date. Unless
otherwise notified, the Participant's Account balance in the Guaranteed
Interest Division will be applied toward a Guaranteed Annuity and the
Participant's Account balance in the Variable Investment Division toward a
Variable Annuity.
 
  The payment amount for a Guaranteed Annuity is determined by dividing the
Participant's Annuity Conversion Amount in the Guaranteed Interest Division as
of the initial Annuity Payment Calculation Date by the applicable Annuity
Conversion Factor.
   
  The initial payment amount for a Variable Annuity is determined by dividing
the Participant's Annuity Conversion Amount(s) in the applicable Sub-Account(s)
as of the initial Annuity Payment Calculation Date by the applicable Annuity
Conversion Factor as defined in the Contract. The amounts of subsequent
payments vary depending on the investment experience of the sub-account(s) of
the Variable Investment Division or of a Variable Payout Division, as
applicable, and the interest rate option selected by the Participant. The
payment amounts will not be affected by mortality or expense experience and
will not be reduced by an Annual Administration Charge. For additional
information on the determination of subsequent payment amounts, refer to the
Statement of Additional Information, "Determination of Variable Annuity
Payments."     
 
                             PAYOUT ANNUITY OPTIONS
 
  Participants are offered a range of annuity options including, but not
limited to, the following:
 
SINGLE LIFE ANNUITY
 
  Payments are made monthly during the lifetime of the Annuitant, and the
annuity terminates with the last payment preceding death.
 
LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR 10, 15 OR 20 YEARS
 
  Payments are made monthly during the lifetime of the Annuitant with a monthly
payment guaranteed to the Beneficiary for the remainder of the selected number
of years, if the Annuitant dies before the end of the period selected. Payments
under this annuity option are smaller than a Single Life Annuity without a
guaranteed payment period.
 
JOINT LIFE ANNUITIES
 
  Payments are made monthly during the joint lifetime of the Annuitant and a
designated second person.
 
NON-LIFE ANNUITIES
 
  Annuity payments are guaranteed monthly for the selected number of years.
While there is no right to make any total or partial withdrawals during the
Annuity Period, an Annuitant who has
 
                                       27
<PAGE>
 
selected this annuity option as a Variable Annuity or a surviving Beneficiary
may request at any time during the payment period that the present value of any
remaining installments be paid in one lump sum. Such lump sum payment will be
treated as a Total Withdrawal during the Accumulation Period and may be subject
to a CDSC. See, "Deductions and Charges" and "Federal Income Tax
Considerations."
 
  Under Qualified Plans, any annuity selected must be payable over a period
that does not extend beyond the life expectancy of the Participant and the
Participant's designated Beneficiary. If the Beneficiary is someone other than
the Participant's spouse, the present value of payments to be made to the
Participant must be more than 50% of the present value of the total payments to
be made to the Participant and the Beneficiary.
 
  In the event that an Annuitant dies before the end of a designated Annuity
period, the Beneficiary, if any, or the Annuitant's estate will receive any
remaining payments due under the annuity option in effect.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion assumes that the Contracts will qualify as annuity
Contracts for Federal income tax purposes. The description of the Federal
income tax status of amounts received under the Contracts is not exhaustive and
is not intended to cover all situations. Contractholders and Participants
should seek advice from their tax advisers on a regular basis as to the
application of Federal (and, where applicable, state and local) tax laws to
amounts received by them or their Beneficiaries under the Contracts. All dollar
amounts and percentages stated below are subject to change according to Federal
law. With respect to the transfer of Contracts from UNUM/America to Lincoln
Life or Lincoln-NY, there will be no adverse tax consequences to
Contractholders or participants as a result of the transfer. For additional
Federal Income Tax Considerations, please refer to the Statement of Additional
Information.
 
                              NON-QUALIFIED PLANS
 
  Under a Non-Qualified Plan, an individual may make Contributions to the
Contract which are neither tax-deductible or tax deferred. The earnings on the
Contributions accumulate on a tax-deferred basis until withdrawn. Non-Qualified
Plans investing in annuity Contracts are subject to the Federal taxation rules
of Section 72 of the Code.
 
  The Code does not limit the Participant's contributions to a Section 72 plan.
There are no Code restrictions on withdrawals or minimum age when the
Participant must begin withdrawals.
   
  Section 401(a) Plans. Section 401(a) of the Code provides special tax
treatment for pension, profit sharing and stock bonus Plans established by
employers for their employees. Contributions to a Section 401(a) Plan and any
earnings attributable to such Contributions are currently excluded from the
Participant's income. Section 401(a) Plans are subject to, among other things,
limitations on: maximum contributions, minimum coverage and participation,
minimum funding, minimum vesting requirements and distribution requirements.
The specific limitations are outlined in the plan document adopted by the
employer.     
 
  A Participant who makes a withdrawal from a Section 401(a) program must
include that amount in current income. In addition, Section 401(k)(2) of the
Code requires that salary reduction
 
  Contributions made and/or earnings credited on any salary reduction
Contributions may not be withdrawn from the Participant's Section 401(k)
program prior to the Participant having (1) attained age 59 1/2, (2) separated
from service, (3) become disabled, (4) died or (5) incurred a hardship.
Hardship withdrawals may not include any income credited after December 31,
1988 that is attributable to any salary reduction Contributions. In addition,
Section 402 of the Code permits
 
                                       28
<PAGE>
 
tax-free rollovers from Section 401(a) programs to individual retirement
annuities or certain other Section 401(a) programs under certain circumstances.
   
  Section 403(B) Plans. A Participant who is an employee of a hospital or other
tax-exempt organization described in Section 501(c)(3) or 501(e) of the Code
may exclude from current earnings amounts contributed to a Section 403(b)
program. Under the terms of a Section 403(b) program, an Employer may make
Contributions directly to the program on behalf of the Participant, the
Participant may enter into a salary reduction agreement with the Participant's
Employer authorizing the Employer to contribute a percentage of the
Participant's salary to the program and/or the Participant may authorize the
Employer to make after tax Contributions to the program. Currently, the Code
permits employees to defer up to $10,000 of their income through salary
agreements. All Contributions made to the Section 403(b) program are subject to
the limitations described in Code Sections 402(g) regarding elective deferral
amounts, 403(b)(2) regarding the maximum exclusion allowance, and 415(a)(2) and
415(c) regarding the limitations on annual additions.     
 
  A Participant who makes a withdrawal from their Section 403(b) program must
include that amount in current income. In addition, Section 403(b)(11) of the
Code requires that salary reduction Contributions made and/or earnings credited
on any salary reduction Contributions after December 31, 1988 may not be
withdrawn from the Participant's Section 403(b) program prior to the
Participant having (1) attained age 59 1/2, (2) separated from service, (3)
become disabled, (4) died or (5) incurred a hardship. Hardship withdrawals may
not include any income credited after December 31, 1988 that is attributable to
any salary reduction Contributions. The Internal Revenue Service has ruled
(Revenue Ruling 90-24) that amounts may be transferred between Section 403(b)
investment vehicles as long as the transferred funds retain withdrawal
restrictions at least as restrictive as that of the transferring investment
vehicle. Such transferred amounts are considered withdrawals under the Contract
and will be subject to a CDSC, if applicable. See "Deductions and Charges--
Contingent Deferred Sales Charges." In addition, Section 403(b)(8) of the Code
permits tax-free rollovers from Section 403(b) programs to individual
retirement annuities or other Section 403(b) programs under certain
circumstances. Qualified distributions eligible for rollover treatment may be
subject to a 20% federal tax withholding depending on whether or not the
distribution is paid directly to an eligible retirement plan.
   
  Section 408 Plans (IRAS). Under current law, individuals may contribute and
deduct the lesser of $2,000 or 100% of their compensation to an IRA. The $2,000
is increased to $4,000 when the IRA covers the taxpayer and a non-working
spouse . The deduction for Contributions is phased out for individuals who are
considered active participants under Qualified Plans and whose Adjusted Gross
Income attains a certain level. In 1998, for a single person the $2,000
deduction is available when the taxpayer's Adjusted Gross Income is $30,000 or
less. For each $50 that the taxpayer's Adjusted Gross Income rises above
$30,000, the taxpayer's deductible IRA is reduced by $10. When the single
taxpayer's Adjusted Gross Income is $40,000 or greater, a tax deduction for an
IRA is no longer available. In 1998, for a married couple filing jointly, the
threshold level is $50,000 rather than $30,000. For a married person filing
separately, the threshold is $0.     
 
  In addition, certain amounts distributed from Section 401(a) and 403(b) Plans
may be rolled over to an IRA on a tax-free basis if done in a timely manner
(within 60 days of the Participant's receipt of the distribution). The
limitations on contributions discussed above do not apply to amounts rolled
over to an IRA.
 
  All Participants in an IRA receive an IRA Disclosure. This document explains
the tax rules that apply to IRAs in greater detail.
 
  Eligible Section 457 Plans. Eligible Section 457 Plans may be established by
state and local governments as well as private tax-exempt organizations (other
than churches). Participants may contribute on a before tax basis to a deferred
compensation Plan of their employer in accordance
 
                                       29
<PAGE>
 
   
with the employer's Plan and Section 457 of the Code. Section 457 places
limitations on the amount of Contributions to these Plans. Generally, the
limitation is one-third of includable compensation or $7,500, as indexed,
whichever is less. In the Participant's final year of employment the $7,500
limit is increased to $15,000.     
 
  Participants in an Eligible 457 Plan may not receive a withdrawal or other
distribution from their Plan except in the event of separation of service from
the employer, attainment of age 70 1/2, or when faced with an unforeseen
emergency. The Contractholder's Plan may further restrict the Participant's
rights to a withdrawal.
          
  An employee electing to participate in an Eligible Section 457 Plan should
understand that their rights and benefits are governed strictly by the terms of
the Plan. Plans of state or local governments established on August 20, 1996,
or later, must hold all assets and income in trust (or custodial accounts or an
annuity contract) for the exclusive benefit of participants and their
beneficiaries. State or local government plans that were in existence before
August 20, 1996 are allowed until January 1, 1999 to meet this requirement.
Non-governmental plans are not subject to this requirement and employees of
these plans are general creditors of the Employer. Participants under Eligible
Section 457 Plans should look to the terms of their Plan for any changes in
regard to participation other than those disclosed in this Prospectus.     
 
  Section 457(f) Plans. Section 457(f) Plans may be established by state and
local governments as well as private tax-exempt organizations. Employers and
Participants may contribute on a before-tax basis to a deferred compensation
Plan of their employer in accordance with the employer's Plan. Section 457(f)
does not place limitations on the amount of Contributions to these Plans;
however, the Internal Revenue Service may review these plans to determine if
the deferral amount is acceptable to the IRS based on the nature of the 457(f)
Plan.
 
  Participants in 457(f) Plans may not receive a withdrawal or other
distribution from their 457(f) Plans until a distributable event occurs. The
Plan will define such events.
 
  An employee electing to participate in a Section 457(f) Plan should
understand that their rights and benefits are governed strictly by the terms of
the Plan, that they are in fact a general creditor of the Employer under the
terms of the Plan, that the Employer is legal owner of any Contract issued with
respect to the Plan and that the Employer retains all rights under the Contract
issued with respect to the Plan. Participants under Section 457(f) Plans should
look to the terms of their Plan for any charges in regard to participating
other than those disclosed in this Prospectus.
 
  Taxation of Annuities: General. In Qualified Plans such as 401(a), 403(b),
408 and Eligible 457 Plans, the Participant is not taxed on the value in their
accounts until they receive payments from the account. In some situations,
default or forgiveness of a loan will result in taxable income. Distributions
from all these Plans are taxed under the rules of Sections 72 and 402 of the
Code.
 
  Taxation Prior to the Annuity Commencement Date. Section 72 of the Code
provides that a total or partial withdrawal prior to the Annuity Commencement
Date will be taxable to the extent the amount of the income in the
Participant's account exceeds the Participant's investment in the Participant's
account. In general, distributions from a Participant's account under Sections
401(a), 403(b) and 408 Plans under which the Participant made after-tax
contributions will be taxable according to a formula based on the ratio of the
Participant's investment in the Contract to the total value of the
Participant's Account balance as of the date of the distribution. Under an
Eligible 457 Plan the Participant is taxed on the value when it is made
available to the Participant. In a 457(f) Plan the Participant is taxed when
their right to a distribution is no longer subject to a substantial risk of
forfeiture.
 
  Penalty Tax for Premature Distributions. Sections 72(q) and 72(t) impose a
10% excise tax on certain premature distributions for non-qualified and Section
401(a), 403(b) and 408 Plans. The penalty tax will not apply to distributions
made on account of the Participant having (i) attained age
 
                                       30
<PAGE>
 
59 1/2; (ii) become disabled; or (iii) died. The penalty tax will also not
apply under 401(a) and 403(b) retirement plans where a Participant separates
from service after age 55. In addition, the penalty does not apply if the
distribution is received as a series of substantially equal periodic payments
made for the life (or life expectancy) of the Participant or the joint lives
(or life expectancies) of the Participant and a designated Beneficiary. The 10%
excise tax is an additional tax; it does not apply to any money that the
Participant receives as a return of their cost basis. The 10% excise tax does
not apply to Section 457 Plans.
 
  Minimum Distributions. Participants in Plans subject to Code Sections 401(a),
403(b), 408 and Eligible 457 Plans are subject to Minimum Distribution Rules.
For a Participant who attains age 70 1/2 after December 31, 1987, distributions
must begin by April 1 of the calendar year following the calendar year in which
the Participant attains age 70 1/2. For a Participant who attains age 70 1/2
before January 1, 1988, distributions must begin on the April 1 of the calendar
year following the later of (1) the calendar year in which the Participant
attains age 70 1/2 or (2) the calendar year in which the Participant retires.
 
                                 VOTING RIGHTS
 
  UNUM/America is the legal owner of the shares of the Funds held by the
Variable Investment Division. As such, UNUM/America is entitled to vote those
Fund shares with respect to issues such as the election of a Fund's directors,
ratification of a Fund's choice of independent auditors and other matters
required by the 1940 Act to be voted on by shareholders.
 
  In those years in which the Funds hold a shareholder meeting, UNUM/America
will solicit from Contractholders voting instructions with respect to Fund
shares held by the Variable Investment Division. Each Contractholder will
receive a number of votes in proportion to the Contractholder's investment in
the corresponding Sub-Account as of the record date established by the Fund.
 
  During the Accumulation Period, a Participant has the right to instruct
Contractholders as to the votes attributable to their Participant Account
balance in the Sub-Accounts. Annuitants have similar rights with respect to the
annuity amount attributable to the Sub-Accounts.
 
  UNUM/America will furnish Contractholders with sufficient Fund proxy material
and voting instruction forms for all Participants who have voting rights under
the Contract. UNUM/America will vote those Fund shares attributable to the
Contract for which UNUM/America receives no voting instructions in the same
proportion as UNUM/America will vote shares for which UNUM/America has received
instructions. UNUM/America will vote shares attributable to amounts
UNUM/America may have in the Variable Investment Division in the same
proportion as votes that UNUM/America receives from Contractholders. If the
federal securities laws or regulations or any interpretation of them changes so
that UNUM/America is permitted to vote shares of the Fund in UNUM/America's own
right or to restrict Participant voting, UNUM/America may do so.
 
  Fund shares may be held by separate accounts of insurance companies
unaffiliated with UNUM/America. Fund shares held by those separate accounts
will be voted, in most cases, according to the instruction of owners of
insurance policies and Contracts issued by those other unaffiliated insurance
companies. This will dilute the effect of the voting instructions of the
Contractholders in the Variable Investment Division. UNUM/America does not
foresee any disadvantage to this. Pursuant to conditions imposed in connection
with regulatory relief, the Fund's Board of Directors has an obligation to
monitor events to identify conflicts that may arise and to determine what
action, if any, should be taken. For further information, see the prospectuses
for the Funds.

                           OTHER CONTRACT PROVISIONS
 
                        RIGHTS RESERVED BY UNUM/AMERICA
 
  UNUM/America reserves the right, subject to compliance with applicable law,
including approval by the Contractholder or the Participants if required by
law, (1) to create additional Sub-Accounts in the Variable Investment Division,
(2) to combine or eliminate Sub-Accounts in the Variable Investment Division,
(3) to transfer assets from one Sub-Account in the Variable Investment Division
to another, (4) to transfer assets to the General Account and other separate
accounts, (5) to cause the deregistration and subsequent re-registration of the
Variable Investment Division under the Investment Company Act of 1940, (6) to
operate the Variable Investment Division under a committee and to discharge
such committee at any time, and (7) to eliminate any voting rights which the
Contractholder or the Participants may have with respect to the Variable
Investment Division, (8) to amend the Contract to meet the requirements of the
Investment Company Act of 1940 or other federal securities laws and
regulations, (9) to operate the Variable Investment Division in any form
permitted by law, (10) to substitute shares of another fund for the shares held
by a Sub-Account, and (11) to make any change required by the Internal Revenue
Code, ERISA or the Securities Act of 1933. Participants will be notified if any
changes are made that result in a material change in the underlying investments
of the Variable Investment Division.
 
                                 ASSIGNABILITY
 
  The Contracts are not assignable without UNUM/America's prior written
consent. In addition, a Participant, a Beneficiary or an Annuitant may not,
unless permitted by law, assign or encumber any payment due under the Contract.
 
                               MARKET EMERGENCIES
 
  While UNUM/America may not suspend the right of redemption or delay payment
from the Variable Investment Division for more than the time period allowed
under Federal law but in no case longer than seven days, the following events
may delay payment for more than seven days: (1) any period when the New York
Stock Exchange is closed (other than customary weekend and holiday closings);
(2) any period when trading in the markets normally utilized is restricted, or
an emergency exists as determined by the Securities and Exchange Commission, so
that disposal of investments or determination of the Accumulation Unit Value or
Variable Annuity payment value is not reasonably practicable; or (3) for such
other periods as the Securities and Exchange Commission by order may permit for
the protection of the Participants.
 
                             CONTRACT DEACTIVATION
 
  Under certain Contracts, UNUM/America may deactivate a Contract by
prohibiting new contributions and/or new Participants after the date of
deactivation. UNUM/America will give the Contractholder and the Participants
not less than 90 days notice of the date of deactivation.
 
                                FREE-LOOK PERIOD
 
  Participants under Sections 403(b), 408 and certain Non-Qualified Plans will
receive an Active Life Certificate upon UNUM/America's receipt of a duly
completed participation enrollment form. If the Participant chooses not to
participate under the Contract, the Participant may exercise the free-look
right by sending a written notice to UNUM/America that the Participant does not
wish to participate under the Contract, within 10 days after the date the
Active Life Certificate is received by the Participant. For purposes of
determining the date on which the Participant has sent written notice, the
postmark date will be used.
 
                                       32
<PAGE>
 
  If a Participant exercises the free-look right in accordance with the
foregoing procedure, UNUM/America will refund in full the Participant's
aggregate Contributions less aggregate withdrawals made on behalf of the
Participant or, if greater, with respect to Contributions to the Variable
Investment Division, the Participant's Account balance in the Variable
Investment Division on the date the Participant's written notice is received by

                              OTHER CONTRACTS     
   
  UNUM/America and the Variable Investment Division offer other group variable
annuity contracts which invest in the same Funds. These contracts may impose
different charges that could affect Sub-Account performance, and may offer
different benefits.     
 
                          GUARANTEED INTEREST DIVISION
 
                                    GENERAL
 
  Contributions to the Guaranteed Interest Division become part of
UNUM/America's General Account. The General Account is subject to regulation
and supervision by the Maine Insurance Department as well as the insurance laws
and regulations of the jurisdictions in which the Contracts are distributed. In
reliance on certain exemptions, exclusions and rules, UNUM/America has not
registered the interests in the General Account as a security under the
Securities Act of 1933 and has not registered the General Account as an
investment company under the 1940 Act.
 
  Accordingly, neither the General Account nor any interests therein are
subject to regulation under the 1933 Act or the 1940 Act. UNUM/America has been
advised that the staff of the SEC has not made a review of the disclosures
which are included in this prospectus which relate to the General Account and
the Guaranteed Interest Division. These disclosures, however, may be subject to
certain generally applicable provisions of the federal securities laws relating
to the accuracy and completeness of statements made in prospectuses. This
prospectus is generally intended to serve as a disclosure document only for
aspects of the Contract involving the Variable Investment Division and contains
only selected information regarding the Guaranteed Interest Division. Complete
details regarding the Guaranteed Interest Division are in the Contract.
 
  Amounts contributed to the Guaranteed Interest Division are guaranteed a
minimum interest rate according to contract minimums of at least 3.0%.
UNUM/America will also declare in advance a guaranteed interest rate which will
be effective for all amounts in the Participant's Account balance in the
Guaranteed Interest Division during the designated year. This rate will never
be less than the minimum rate of interest. UNUM/America may also declare in
advance separate interest rate guarantees which are in excess of the guaranteed
interest rate for some or all of the Participant's Account balance in the
Guaranteed Interest Division for specific period(s) during the designated year.
A Participant who makes a Contribution to the Guaranteed Interest Division is
credited with interest beginning on the next calendar day following the date of
receipt if all Participant data is complete.
 
       PARTICIPANT'S ACCOUNT BALANCE IN THE GUARANTEED INTEREST DIVISION
 
  The Participant's Account balance in the Guaranteed Interest Division on any
Valuation Date will reflect the amount and frequency of any Contributions
allocated to the Guaranteed Interest Division, plus any transfers from the
Variable Investment Division and interest credited to the Guaranteed Interest
Division, less any withdrawals, CDSC, Annual Administration Charges and loan-
related charges allocated to the Guaranteed Interest Division and any transfers
to the Variable Investment Division.

<PAGE>
 
                    TRANSFERS, TOTAL AND PARTIAL WITHDRAWALS
 
  Amounts in the Guaranteed Interest Division are generally subject to the same
rights and limitations and will be subject to the same charges as are amounts
allocated to the Variable Investment Division with respect to Total or Partial
Withdrawals. See "Deferral Periods."
 
                                     LOANS
 
  During a Participant's Accumulation Period, a Participant, whose Plan permits
loans, may apply for a loan under the Contract by completing a loan application
available from UNUM/America. Loans are secured by the Participant's Account
balance in the Guaranteed Interest Division. The amounts and terms of a
Participant loan may be subject to the restrictions imposed under Section 72(p)
of the Code, Title I of ERISA, and any applicable Plans. With respect to Plans
subject to Title I of ERISA, the initial amount of a Participant loan may not
exceed the lesser of 50% of the Participant's vested Account balance in the
Guaranteed Interest Division or $50,000 and must be at least $1,000. A
Participant in a Plan that is not subject to ERISA may borrow up to $10,000 of
their vested Account balance without regard to the 50% limitation stated above.
A Participant may have only one loan outstanding at any time and may not
establish more than one loan in any six month period. Amounts serving as
collateral for the loan are not subject to the minimum interest rate under the
Contract and will accrue interest at a rate which is below the loan interest
rate as provided in the Contract. Under certain Contracts, a one-time fee of up
to $50 may be charged to set up a loan. More information about loans, including
interest rates and applicable fees and charges, is available in the Contracts,
Active Life Certificates, and the Annuity Loan Agreement as well as from
UNUM/America.
 
                                DEFERRAL PERIODS
 
  If a payment is to be made from the Guaranteed Interest Division,
UNUM/America may defer the payment for the period permitted by the law of the
jurisdiction in which the Contract is distributed, but in no event, for more
than 6 months after a written election is received by UNUM/America. During the
period of deferral, interest at the then current interest rate will continue to
be credited to a Participant's Account in the Guaranteed Interest Division.

                          PREPARING FOR YEAR 2000     
   
  Lincoln Life is, as noted at page 13 above, responsible for administering the
Contracts and the Variable Investment Division on behalf of UNUM/America.
Lincoln Life's responsibilities include the operation of the computer systems
related to the Variable Investment Division, which are distinct from those used
by UNUM/America in its other operations. Many existing computer programs use
only two digits to identify a year in the date field. These programs were
designed and developed without considering the impact of the upcoming change in
the century. If not corrected, many computer applications could fail or create
erroneous results by or at the year 2000. The year 2000 issue affects virtually
all companies and organizations. Since Lincoln Life operates and is responsible
for the updating of the Variable Investment Division-related computer programs,
and the computer systems used by UNUM/America in other businesses are not
integrated with these systems, this prospectus describes the year 2000 updating
efforts of Lincoln Life for these systems, rather than those of UNUM/America
with respect to computer systems used in its other businesses. An affiliate of
Lincoln Life, Delaware Service Company (Delaware), provides substantially all
of the necessary accounting and valuation services for the Variable Investment
Division. Delaware, for its part, is responsible for updating all of its
computer systems, including those which service the Variable Investment
Division, to accommodate the year 2000. Lincoln Life and Delaware have begun
formal discussions with each other to assess the requirements for their
respective systems to interface     
 
                                       34
<PAGE>
 
   
properly in order to facilitate the accurate and orderly operation of the
Variable Investment Division beginning in the year 2000.     
   
  The year 2000 issue is pervasive and complex and affects virtually every
aspect of the businesses of both Lincoln Life and Delaware (the Companies). The
computer systems of the Companies and their interfaces with the computer
systems of vendors, suppliers, customers and other business partners are
particularly vulnerable. The inability to properly recognize date-sensitive
electronic information and to transfer data between systems could cause errors
or even complete failure of systems, which would result in a temporary
inability to process transactions correctly and engage in normal business
activities for the Variable Investment Division. The Companies respectively are
redirecting significant portions of their internal information technology
efforts and are contracting, as needed, with outside consultants to help update
their systems to accommodate the year 2000. Also, in addition to the
discussions with each other noted above, the Companies have respectively
initiated formal discussions with other critical parties that interface with
their systems to gain an understanding of the progress by those parties in
addressing year 2000 issues. While the Companies are making substantial efforts
to address their own systems and the systems with which they interface, it is
not possible to provide assurance that operational problems will not occur. The
Companies presently believe that, assuming the modification of existing
computer systems, updates by vendors and conversion to new software and
hardware, the year 2000 issue will not pose significant operations problems for
their respective computer systems. In addition, the Companies are incorporating
potential issues surrounding year 2000 into their contingency planning process,
in the event that, despite these substantial efforts, there are unresolved year
2000 problems. If the remediation efforts noted above are not completed timely
or properly, the year 2000 issue could have a material adverse impact on the
operation of the businesses of Lincoln Life or Delaware, or both, and/or the
processing of transactions involving the Variable Investment Division.     
   
  The cost of addressing year 2000 issues and the timeliness of completion will
be closely monitored by management of the respective Companies. Nevertheless,
there can be no guarantee that estimated costs will be achieved, and actual
results could differ significantly from those anticipated. Specific factors
that might cause such differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer problems, and other uncertainties.

                  DETERMINATION OF VARIABLE ANNUITY PAYMENTS
   
As stated in the prospectus, the amount of each Variable Annuity payment will
vary depending on investment experience.     
 
The initial payment amount of the Annuitant's Variable Annuity for each Sub-
Account is determined by dividing his Annuity Conversion Amount in each Sub-
Account as of the initial Annuity Payment Calculation Date by the Applicable
Annuity Conversion Factor as defined as follows:
 
The Annuity Conversion Factors which are used to determine the initial
payments are based on the 1983 Individual Annuity Mortality Table, set back
four (4) years, and an interest rate in an integral percentage ranging from
zero to six percent (0 to 6.00%) as selected by the Annuitant.
 
The amount of the Annuitant's subsequent Variable Annuity payment for each
Sub-Account is determined by:
 
(a)   Dividing the Annuitant's initial Variable Annuity payment amount by the
      Annuity Unit Value for that Sub-Account selected for his interest rate
      option as described above as of his initial annuity Payment Calculation
      Date; and
 
(b)   Multiplying the resultant number of annuity units by the Annuity Unit
      Values for the Sub-Account selected for his interest rate option for his
      respective subsequent Annuity Payment Calculation Dates.
 
The Annuity Unit Value for all Sub-Accounts for all interest rate options will
initially be set at ten dollars ($10). Each subsequent Annuity Unit Value for
a Sub-Account for an interest rate option is determined by:
 
    Dividing the Accumulation Unit Value for the Sub-Account as of
    subsequent Annuity Payment Calculation Date (APCD) by the Accumulation
    Unit Value for the Sub-Account as of the immediately preceding APCD;
 
    Dividing the resultant factor by one (1.00) plus the interest rate
    option to the n/365 power where n is the number of days from the
    immediately preceding APCD to the subsequent APCD; and
 
    Multiplying this factor times the Annuity Unit Value as of the
    immediately preceding APCD.

                           PERFORMANCE CALCULATIONS
 
STANDARD TOTAL RETURN CALCULATION
 
The Variable Investment Division may advertise average annual total return
information calculated according to a formula prescribed by the Securities and
Exchange Commission ("SEC"). Average annual total return shows the average
annual percentage increase, or decrease, in the value of a hypothetical
Contribution allocated to a Sub-Account from the beginning to the end of each
specified period of time. The SEC standardized version of this performance
information is based on an assumed Contribution of $1,000 allocated to a Sub-
Account at the beginning of each period and surrender or withdrawal of the
value of that amount at the end of each specified period, giving effect to any
CDSC and all other charges and fees applicable under the Contract. The effect
of the Annual Administration Charge for a period is determined by dividing the
total amount of such charges collected in the previous year by the total
average net assets of the accounts for the previous year, as of the previous
month ended; accounts include accounts available under Variable Annuity II of
UNUM/America and under corresponding accounts of Lincoln Life, pending
assumption reinsurance by Lincoln Life of Variable Annuity II contracts issued
through such UNUM/America accounts. This method of calculating performance
further assumes that (i) a $1,000 Contribution was allocated to a Sub-Account
and (ii) no transfers or additional payments were made. Premium taxes are not
included in the terms "charges" for purposes of this calculation. Average
annual total return is calculated by finding the average annual compounded
rates of return of a hypothetical Contribution that would compare the
Accumulation Unit value on the first day of the specified period to the ending
redeemable value at the end of the period according to the following formula:
 
  T = (ERV/C) 1/n - 1
 
Where T equals average annual total return, where ERV (the ending redeemable
value) is the value at the end of the applicable period of a hypothetical
Contribution of $1,000 made at the beginning of the applicable period, where C
equals a hypothetical Contribution of $1,000, and where n equals the number of
years.
   
For Sub-Account average annual total return information calculated according
to the formula prescribed by the SEC, see "Sub-Account Performance."     
 
NON-STANDARDIZED CALCULATION OF TOTAL RETURN PERFORMANCE
   
In addition to the standardized average annual total return information
described above, we may present total return information computed on bases
different from that standardized method. Such non-standard performance
information may be based on the historical performance of a Fund and adjusted
to reflect some or all of the fees and charges imposed under a Contract.     
   
The Variable Investment Division also may present total return information
computed on the same basis as the standardized method except that charges
deducted from the hypothetical Contribution will not include any CDSC.
Consistent with the long-term investment and retirement objectives of the
Contract, this total return presentation assumes either (i) investment in the
Contract continues beyond the Accumulation Period and/or (ii) one or more of
the conditions for Total or Partial Withdrawal without incurring a CDSC are
met. The Variable Investment Division may also present total return
information computed on the same basis as the standardized method except that
charges deducted from the hypothetical Contribution will not include either
the CDSC or the Annual Administration Charge. The total return percentage
under both of these non-standardized methods will be higher than that
resulting from the standardized method.     
   
The Sub-Accounts also may present total return information calculated by
subtracting a Sub-Account's Accumulation Unit Value at the beginning of a
period from the Accumulation Unit Value of that Sub-Account at the end of the
period and dividing that difference (in that Sub-Account's Accumulation Unit
Value) by the Accumulation Unit Value of that Sub-Account at the beginning of
the period. This computation results in a total growth rate for the specified
period which we annualize in order to obtain the average annual percentage
change in the Accumulation Unit Value for the period used. This method of
calculating performance does not take into account CDSC, the Contract Annual
Administration Charge or premium taxes, and assumes no transfers. Such
percentages would be lower if these charges were included in the calculation.

In addition, the Variable Investment Division may present actual aggregate
total return figures for various periods, reflecting the cumulative change in
value of an investment in the Variable Investment Division for the specified
period.
   
For information regarding the historical performance of the Funds adjusted for
the fees and charges imposed under a Contract, see "Historical Fund
Performance Adjusted for Variable Investment Division and Contract Fees and
Charges."     
 
PERFORMANCE INFORMATION
   
The tables below provide performance information for each Sub-Account for
specified periods ending December 31, 1997. The performance information is
based on historical performance of the underlying Funds adjusted for charges
applicable to the Variable Annuity I Separate Account. THIS INFORMATION DOES
NOT INDICATE OR REPRESENT FUTURE PERFORMANCE.     
 
TOTAL RETURN
 
Total returns quoted in sales literature or advertisements reflect all aspects
of a Sub-Account's return. Average annual returns are calculated by
determining the growth or decline in value of a hypothetical historical
investment in the Sub-Account over a stated period of time, and then
calculating the annually compounded percentage rate that would have produced
the same result if the rate of growth or decline had been constant over the
period. Contractholders and participants should recognize that average annual
returns represent averaged returns rather than actual year-to-year
performance.
          
SUB-ACCOUNT PERFORMANCE     
   
The tables below assume a hypothetical investment of $1,000 at the beginning
of the period in the Sub-Account investing in the applicable Fund and
withdrawal of the investment on 12/31/97. The rates thus reflect the mortality
and expense risk charge, the withdrawal charge and a pro rata portion of the
Annual Administration Charge. The first table shows Sub-Account average annual
total return information calculated according to the formula prescribed by the
SEC. The second table shows Sub-Account cumulative total return information.

HISTORICAL FUND PERFORMANCE ADJUSTED FOR VARIABLE INVESTMENT DIVISION AND
CONTRACT FEES AND CHARGES     
   
Performance information for the periods prior to the date the Sub-Accounts
commenced operations will be calculated based on the performance of the Funds
and the assumption that the Sub-Accounts were in existence for the same
periods as those indicated for the Funds, with the Contract charges that were
in effect during the time periods shown. This performance information is
referred to as "adjusted" performance information. THIS INFORMATION DOES NOT
INDICATE OR REPRESENT FUTURE PERFORMANCE.

Table 1A below assumes a hypothetical investment of $1,000 at the beginning of
the period in the Sub-Account investing in the applicable fund and withdrawal
of the investment on 12/31/97. The rates thus reflect the mortality and
expense risk charge, the withdrawal charge and a pro rata portion of the
Annual Administration Charge. Table 1B shows the cumulative total return on
the same basis.

*The above calendar-year returns assume a hypothetical investment of $1,000 on
January 1 of the first full calendar year that the underlying fund was in
existence. The returns assume that the money will be left on account until
retirement and thus no CDSC will be deducted. Returns are provided for years
before the fund was an available investment option under the Contract. Returns
for those periods reflect a hypothetical return as if those funds were
available under the Contract, and reflect the deduction of the mortality and
expense risk charge. The returns do not reflect deductions for the pro rata
portion of the Annual Administration Charge or the CDSC.
 
                            TAX LAW CONSIDERATIONS
 
RETIREMENT PROGRAMS:
 
Participants are urged to discuss the income tax considerations of their
retirement plan with their tax advisors. In many situations special rules may
apply to the plans and/or to the participants.
 
Contributions to retirement programs subject to Sections 401(a), 403(a),
403(b), 408 and 457(b) may be excludable from a Participant's reportable gross
income if the Contributions do not exceed the limitations imposed under the
Code. Certain plans allow employees to make Elective Salary Deferral
Contributions. Certain Plans allow Employers to make Contributions. The
information below is a brief summary of some of the important federal tax
considerations that apply to retirement plans. The Code requires that 401(a)
Plans and certain 403(b) Plans be in writing and that the Employer communicate
the provisions of the Plans to employees. When there is a written Plan, often
the Contribution limits, withdrawal rights and other provisions of the Plan
may be more restrictive than those allowed by the Code.
 
                    Elective Salary Deferral Contributions:
          
For calendar year 1998 the maximum elective salary deferral contributions to a
401(k) Plan which is a type of 401(a) Plan is limited to $10,000; for a 403(b)
plan the limit is $10,000 unless the employee is a qualified employee; for an
Eligible 457 Plan the limit is $8,000.     
 
                Total Salary Deferral & Employer Contributions:
 
QUALIFIED RETIREMENT PLAN -- 401(a) PLAN
 
The Code limits the Contributions to a defined contribution 401(a) plan to the
lesser of $30,000 or 25% of compensation.
 
                                      11
<PAGE>
 
TAX SHELTERED ANNUITY PLAN -- 403(b) PLAN
 
Total Contributions which include both salary deferral Contributions and
Employer Contributions are also limited.
 
The combined limit is:
 
(a) the amount determined by multiplying 20 percent of the employee's
    includable compensation by the number of years of service, over
 
(b) the aggregate of the amount contributed by the Employer for annuity
    contracts and excludable from the gross income of the employee for the
    prior taxable year.
   
Therefore, if the maximum exclusion allowance is less than $10,000 a year, the
employee's elective deferrals plus any other Employer Contributions cannot
exceed this lesser amount.     
 
Section 415 of the Code imposes limitations with respect to annual
contributions to all Section 403(b) programs, qualified plans and simplified
employee pensions maintained by the Employer. A Participant's annual
Contributions to these programs and defined contribution plans cannot exceed
the lesser of $30,000 or 25 percent of the employee's compensation. This
amount is subject to the maximum exclusion allowance and the salary deferral
amount limitations.
 
ELIGIBLE 457 PLAN -- 457(b) PLAN
   
For a 457(b) plan the contribution is the lesser of $7,500, as indexed, or 33%
of the employee's compensation.     
 
SECTION 457(f) PLANS
 
These are non-qualified deferred compensation arrangements between an Employer
and its employees. There are no stated limits in the Code regarding this type
of Plan.
 
INDIVIDUAL RETIREMENT ACCOUNT -- IRA OR 408 PLAN
 
For IRA's the maximum deductible contribution is the lesser of $2,000 or 100%
of taxable income. The $2,000 is increased to $4,000 when the IRA covers the
taxpayer and a non-working spouse.
 
TRANSFERS AND ROLLOVERS:
 
Participants who receive distributions from their 401(a) or 403(b) contract
may transfer the amount not representing employee Contributions to an
Individual Retirement Account or Annuity (IRA) or another Section 401(a) or
403(b) program without including that amount in gross income for the taxable
year in which paid. Note 401(a) distributions may not be transferred to a
403(b) plan or vice versa. If the rollover amount is paid directly to the
Participant, the amount distributed may be subject to a 20% federal tax
withholding. If the amount is paid directly to an acceptable rollover account,
UNUM/America is not required to withhold any amount. In order for the
distribution to qualify for rollover, the distribution must be made on account
of the employee's death, after the employee attains age 59 1/2, on account of
the employee's separation from service, or after the employee has become
disabled. The distribution cannot be part of a series of substantially equal
payments made over the life expectancy of the employee or the joint life
expectancies of the employee and his or her spouse or made for a specified
period of 10 years or more. The rollover must be made within sixty days of the
distribution. Pursuant to Revenue Ruling 90-24, a Participant, to the extent
permitted by any applicable Contract or Plan, may transfer funds between
Section 403(b) investment vehicles, including both Section 403(b)(1) annuity
contracts and Section 403(b)(7) custodial accounts. Any amount transferred
must continue to be subject to withdrawal restrictions at least as restrictive
as that of the transferring investment vehicle. UNUM/America considers any
total or partial transfer from a UNUM/America investment vehicle to a non-
UNUM/America investment vehicle to be a withdrawal.
 
Once every twelve months a participant in an IRA may roll the money from one
IRA to another IRA.
 
In Eligible 457 Plans and in Section 457(f) Plans, the Employer controls the
movement of assets from one funding vehicle to another.
 
                                      12
<PAGE>
 
EXCISE TAX ON EARLY DISTRIBUTIONS:
 
Section 72(t) of the Code provides that any distribution made to a Participant
in a 401(a), 403(b) or 408 plan other than on account of the following events
will be subject to a 10 percent excise tax on the taxable amount distributed:
 
a) the employee has attained age 59 1/2;
 
b) the employee has died;
 
c) the employee is disabled;
 
d) the employee is 55 and has separated from service (Does not apply to
   IRA's).
   
Distributions which are received as a life annuity where payment is made at
least annually will not be subject to an excise tax. Certain amounts paid for
medical care may also not be subject to an excise tax. Distributions from 408
Plans may qualify for additional exceptions.     
 
MINIMUM DISTRIBUTION RULES:
 
The value in a Contract under Sections 401(a), 403(b) and 408 are subject to
the distribution rules provided in Section 401(a)(9) of the Code. Generally,
that section requires that an employee must begin receiving distributions of
his post-1986 balance by April 1 of the calendar year following the calendar
year in which the employee attains age 70 1/2. Such distributions must not
exceed the life expectancy of the employee or the life expectancy of such
employee and the designated beneficiary (as defined under the plan). An
employee who attained age 70 1/2 before January 1, 1988 must begin receiving
distributions by April 1 of the calendar year following the later of (a) the
calendar year in which the employee attains age 70 1/2 or (b) the calendar
year in which the employee retires. There are special rules for Section 403(b)
Plans.
 
Amounts contributed to an Eligible 457 Contract must be distributed not
earlier than the earliest of: 1) calendar year in which the Participant
attains age 70 1/2, 2) the Participant separates from service with the
Employer, or 3) when the Participant has an unforeseen emergency. However, in
no event may the distribution begin any later than described in Sections
401(a)(9) and 457(d) of the Code.
 
Additionally, distribution of an employee's entire Account balance (including
pre-1987 funds) must satisfy the minimum distribution incidental benefit
requirement. In general, this requires that death and other non-retirement
benefits payable under the above plans be incidental to the primary purpose of
the program which is to provide deferred compensation to the employee. A payee
is subject to a penalty for failing to receive the required minimum annual
distribution. Section 4974(a) of the Code provides that a payee will be
subject to a penalty equal to 50 percent of the amount by which the required
minimum distribution exceeds the actual amount distributed during the taxable
year.
 
Additional information on federal income taxation is included in the
prospectus.
 
                           DISTRIBUTION OF CONTRACTS
   
Lincoln Financial Advisors Corporation ("LFA"), an indirect subsidiary of
Lincoln National Corporation, is registered with the Securities and Exchange
Commission as a broker-dealer under the Securities Exchange Act of 1934 and is
a member of the National Association of Securities Dealers, Inc. LFA is the
Variable Investment Division's principal underwriter and also enters into
selling agreements with other unaffiliated broker-dealers authorizing them to
offer the Contracts. LFA will pay these unaffiliated broker-dealers a
distribution allowance which will be used to pay commissions to their
registered representatives. This distribution allowance will not be deducted
from Participant Contributions or Account balances but will be paid from
UNUM/America's General Account assets (including any charges collected).     
   
UNUM Sales Corporation, which served as the principal underwriter to the
Variable Investment Division prior to October 1, 1996, received underwriting
commissions from UNUM/America of $4,223,000 and $6,130,700 in 1996 and 1995,
respectively. LFA, which became principal underwriter on October 1, 1996,
received no underwriting commissions from UNUM/America prior to December 31,
1997.

 Company of America VA-1 Separate Account
 
We have audited the accompanying statement of assets and liabilities of UNUM
Life Insurance Company of America VA-1 Separate Account as of December 31,
1997, and the related statements of operations and changes in net assets for
each of the two years in the period then ended. 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. Our
procedures included confirmation of investments held by the custodian as of
December 31, 1997. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of UNUM Life Insurance Company
of America VA-1 Separate Account at December 31, 1997, and the results of its
operations and changes in net assets for each of the two years in the period
then ended in conformity with generally accepted accounting principles.

        VA-1 SEPARATE ACCOUNT OF UNUM LIFE INSURANCE COMPANY OF AMERICA
 
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. ORGANIZATION AND ACCOUNTING POLICIES
 
Organization:
 
VA-1 Separate Account of UNUM Life Insurance Company of America ("UNUM
America") is registered under the Investment Company Act of 1940. The Separate
Account was established in accordance with the laws of the State of Maine. Its
registration statement became effective in December 1989. The assets are held
for the exclusive benefit of the variable annuity contract owners and may not
be used to satisfy any obligations that may arise from any other business
conducted by UNUM America. Any excess of assets over reserves and other
contract liabilities may be transferred to UNUM America's General Account.
Principal markets are hospitals and non-profit organizations located
throughout the United States of America, with specific concentrations in the
states of New York and California.
 
On October 1, 1996, UNUM America completed the sale of its group tax-sheltered
annuity ("TSA") business to The Lincoln National Life Insurance Company
("Lincoln Life") and Lincoln Life & Annuity Company of New York ("Lincoln New
York"), a wholly owned subsidiary of Lincoln Life. At the time of the sale,
the fair value of Separate Account assets was approximately $436,590,000. The
contracts were initially reinsured on an indemnity basis. Upon consent of the
TSA contractholders and/or participants, the contracts are considered
reinsured on an assumption basis, legally releasing UNUM America from future
contractual obligation to the respective contractholders and/or participants.
Assets attributable to such participants' contracts are then transferred to
separate accounts of Lincoln Life and Lincoln New York. Assets attributable to
contracts of participants with respect to which such consent is not obtained
will remain in the Separate Account. During 1997, the net assets of the
Separate Account decreased by approximately $502,568,000 from novations of
assets to the separate accounts of Lincoln Life and Lincoln New York.
 
Investments:
 
In accordance with the terms of the variable annuity contracts, all payments
transferred to the Separate Account by the contract owners are allocated to
purchase shares of either Dreyfus Stock Index Fund, Dreyfus Variable
Investment Fund: Small Cap Portfolio ("Dreyfus Small Cap Portfolio"), the
American Century Variable Portfolios: American Century VP Capital Appreciation
("American Century VP Capital Appreciation Portfolio") and American Century VP
Balanced ("American Century VP Balanced Portfolio"), Fidelity's Variable
Insurance Products Fund: Growth Portfolio ("VIPF Growth Portfolio"),
Fidelity's Variable Insurance Products Fund II: Asset Manager Portfolio ("VIPF
II Asset Manager Portfolio"), Fidelity's Variable Insurance Products Fund:
Equity-Income Portfolio ("VIPF Equity-Income Portfolio"), Calvert Responsibly
Invested Balanced Portfolio or T. Rowe Price International Series, Inc. ("T.
Rowe Price International Series"). Fidelity's Variable Insurance Products
Funds: Money Market Portfolio ("VIPF Money Market Portfolio") is used only for
investment of initial contributions for which UNUM America has not received
complete order instructions. Upon receipt of complete order instructions, the
payments transferred to VIPF Money Market Portfolio are allocated to purchase
shares of one of the above funds.
 
The Separate Account is fully invested in shares of Dreyfus Stock Index Fund,
Dreyfus Small Cap Portfolio, American Century VP Capital Appreciation
Portfolio, American Century VP Balanced Portfolio, VIPF Growth Portfolio, VIPF
II Asset Manager Portfolio, VIPF Equity-Income Portfolio, Calvert Responsibly
Invested Balanced Portfolio, T. Rowe Price International Series and VIPF Money
Market Portfolio, which are carried at market value. Security transactions are
recorded on the trade date. All contracts participating in the Separate
Account are in the accumulation phase. Dividends are fully reinvested and
immediately credited to participant accounts with the exception of VIPF Money
Market Portfolio which is invested monthly. Unrealized gain and loss represent
the difference between the cost and market value of invested assets. Realized
gain and loss are reported on an average cost basis. Gross unrealized gains
for all investments were $4,936,088 as of December 31, 1997 and $77,317,207 as
of December 31, 1996. Gross unrealized losses for all investments were $7,471
as of December 31, 1997 and $0 as of December 31, 1996.

Contract Charges:
 
UNUM America is the depositor for the Separate Account. Administrative services
necessary for the operation of the Separate Account and the variable annuity
contracts are provided by UNUM America. Although UNUM America deducts for sales
and administrative expenses under the contracts, UNUM America assumes an
expense risk that these deductions may prove insufficient to cover the cost of
those expenses.
 
In addition, UNUM America assumes a mortality risk under the contracts in that
it agrees to make annuity payments regardless of how long a particular
annuitant or their payee lives and how long all annuitants or other payees in a
class live, if payment options involving life contingencies are chosen. Those
annuity payments are determined in accordance with annuity purchase rate
provisions established at the time the contracts are issued. UNUM America also
assumes a mortality risk in providing a death benefit under the contracts.
 
To compensate UNUM America for assuming these mortality and expense risks, an
effective annual mortality and expense risk charge of 1.20% of each portfolio's
average daily net assets is imposed on each portfolio within the Separate
Account with the exception of VIPF Money Market Portfolio. For 1997 and 1996,
the mortality and expense risk charges totaled $1,460,336 and $4,927,857,
respectively.
 
Federal Income Taxes:
 
  For purposes of federal income taxes, the Separate Account is considered to
be part of UNUM America for the years ended December 31, 1997 and 1996, and its
operations are not taxed separately. The liability for any federal income taxes
generated by the Separate Account is attributable to UNUM America. UNUM America
is taxed as a property and casualty insurance company under the applicable
provisions of the Internal Revenue Code.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
 UNUM Life Insurance Company of America
 
  We have audited the accompanying balance sheets of UNUM Life Insurance
Company of America as of December 31, 1997 and 1996, and the related
statements of income, stockholder's equity, and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit incudes 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 our audits provide a reasonable basis for
our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of UNUM Life Insurance
Company of America as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

SUPPLEMENTAL DISCLOSURE OF NONCASH OPERATING AND INVESTING ACTIVITIES:
 
As discussed in Note 5, "Sale of Tax-Sheltered Annuity Business," consent for
assumption reinsurance has been given by contractholders and participants
owning approximately 92% of assets under management related to the tax-
sheltered annuity business UNUM America sold in 1996. In connection with the
consents received during 1997, UNUM America reduced its deposit assets by
$2,282 million, policy loan assets by $103.5 million, other policyholder fund
liabilities by $2,447.8 million and separate account assets and liabilities by
$502.6 million.
 
In conjunction with the sale of UNUM America's tax sheltered annuity business
during 1996, fixed maturities available for sale of $588.6 million and short-
term investments of $1,825.9 million were transferred to the buyer on October
1, 1996. Upon transfer, there was a corresponding increase in UNUM America's
deposit assets.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Basis of Presentation
 
The accompanying financial statements of UNUM Life Insurance Company of
America ("UNUM America") have been prepared on the basis of generally accepted
accounting principles. UNUM America is jointly owned by UNUM Holding Company
and UNUM Corporation. UNUM Holding Company is wholly-owned by UNUM
Corporation. The 1995 financial statements have been restated to include the
accounts of Commercial Life Insurance Company ("Commercial Life") which was
merged with UNUM America effective December 31, 1996. 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.
 
Reclassification
 
Certain 1996 and 1995 amounts have been reclassified in 1997 for comparative
purposes.
 
Investments
 
Investments are reported as follows:
 
  . Fixed maturities available for sale (certain bonds and redeemable
    preferred stocks)--at fair value.
  . Equity securities available for sale (common stocks and non-redeemable
    preferred stocks)--at fair value.
  . Mortgage loans--at amortized cost less an allowance for probable losses.
  . Real estate--at cost less accumulated depreciation.
  . Policy loans--at unpaid principal balance.
  . Other long-term investments--at cost plus UNUM America's equity in
    undistributed net earnings since acquisition.
  . Short-term investments--are considered available for sale and are carried
    at cost which approximates fair value.
 
Fixed maturities and equity securities are classified as available for sale as
they may be sold in response to changes in interest rates, resultant
prepayment risk, liquidity and capital needs or other similar economic
factors. Unrealized gains and losses related to securities classified as
available for sale are excluded from net income and reported in a separate
component of stockholders' equity, net of applicable deferred taxes and
related adjustments to unpaid claims and claim expenses. The unrealized gains
and losses are determined based on estimated market values at the balance
sheet date and are not necessarily the amounts which would be realized upon
sale of the securities or representative of future market values. Changing
interest rates affect the level of unrealized gains and losses related to
securities classified as available for sale. While rising interest rates are
beneficial when investing current cash flows, they can also reduce the fair
value of existing fixed rate long-term investments. In addition, lower
interest rates can lead to early payoffs and refinancing of some of UNUM
America's fixed rate investments. Management generally invests in fixed rate
instruments that are structured to limit the exposure to such reinvestment
risk.
 
Realized investment gains and losses, which are determined on the basis of
specific identification and include adjustments for allowances for probable
losses, are reported separately in the Statements of Income.
 
If a decline in fair value of an invested asset is considered to be other than
temporary or if a long-lived asset is deemed to be permanently impaired, the
investment is reduced to its net realizable value and the reduction is
accounted for as a realized investment loss.
 
UNUM America discontinues the accrual of investment income on invested assets
when it is determined that collectability is doubtful. UNUM America recognizes
investment income on impaired loans when the income is received.

                    UNUM LIFE INSURANCE COMPANY OF AMERICA
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
Real estate held for sale is included in other assets in the Balance Sheets
and is valued net of a valuation allowance which reduces the carrying value to
the lower of fair value less estimated costs to sell or cost. This valuation
allowance is periodically adjusted based on subsequent changes in UNUM
America's estimate of fair value less costs to sell.
 
Purchases and sales of short-term financial instruments are part of investing
activities and not necessarily a part of the cash management program.
Therefore, short-term financial instruments are classified as investments in
the Balance Sheets and are included as investing activities in the Statements
of Cash Flows.
 
Deferred Policy Acquisition Costs
 
The costs of acquiring new business that vary with and are related primarily
to the production of new business have been deferred to the extent such costs
are deemed recoverable from future profits. Such costs include commissions,
certain costs of policy issue and underwriting and certain variable field
office expenses.
 
For individual disability, group disability, and group life and health
business, the costs are amortized in proportion to expected future premiums.
For universal life products, the costs are amortized in proportion to
estimated gross profits from interest margins, mortality and other elements of
performance under the contracts. Amortization is adjusted periodically to
reflect differences between actual experience and original assumptions, with
any resulting changes reflected in current operating results. The amounts
deferred and amortized were as follows:

Separate Accounts
 
Certain assets from tax-sheltered annuity ("TSA") contracts are in separate
accounts that are pooled investment funds of securities. Prior to January 1,
1997, the assets of UNUM America's defined benefit plan were held in the
separate accounts (see Note 8 "Employee Benefit and Incentive Plans").
Investment income and realized gains and losses on these accounts accrue
directly to the contractholders. Assets, carried at market value, and
liabilities of the separate accounts are shown separately in the Balance
Sheets. The assets of the separate accounts are legally segregated and are not
subject to claims that arise out of any other business of UNUM America.
 
On October 1, 1996, UNUM America closed the sale of its TSA business to The
Lincoln National Life Insurance Company, a subsidiary of Lincoln National
Corporation (see Note 5 "Sale of Tax-Sheltered Annuity Business"). For legal
considerations, the separate account's TSA related assets were not transferred
on October 1, 1996. TSA related assets are transferred only upon receipt of a
contractholder and participant's consent for assumption reinsurance.
 
Accounting for Participating Individual Life Insurance
 
Participating policies issued by the former Union Mutual Life Insurance
Company ("Union Mutual") prior to UNUM America's conversion to a stock life
insurance company on November 14, 1986, will remain participating as long as
they remain in force. A Participation Fund Account ("PFA") was established for
the benefit of all of Union Mutual's individual participating life and annuity
policies and contracts.
 
The assets of the PFA provide for the benefit, dividend and certain expense
obligations of the participating individual life insurance policies and
annuity contracts. This line of business participates in the experience of the

<PAGE>
 
                    UNUM LIFE INSURANCE COMPANY OF AMERICA
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
PFA and its operations have been excluded from the Statements of Income. The
PFA represented approximately 3.7% and 2.9% of total assets and 4.6% and 3.4%
of total liabilities at December 31, 1997, and 1996, respectively.
 
Other Policyholder Funds
 
Other policyholder funds are liabilities for investment-type contracts and
represent customer deposits plus interest credited to those deposits at
various rates.
 
Liabilities for Restructuring Activities
 
Liabilities for restructuring activities are recorded when management, prior
to the balance sheet date, commits to execute an exit plan that will result in
the incurral of costs that have no future economic benefit or approves a plan
of termination and communicates sufficient detail of the plan to employees.
Liabilities for restructuring activities are included in other liabilities in
the Balance Sheets.
 
Income Taxes
 
The provision for income taxes includes amounts currently payable and deferred
income taxes, which result from differences between financial reporting and
tax bases of assets and liabilities and are measured using enacted tax rates
and laws. A valuation allowance is established for deferred tax assets when it
is more likely than not that an amount will not be realized.
 
Foreign Currency Translation
 
UNUM America has several branch operations located in foreign countries, the
largest being in Canada. These branches generally maintain their balance sheet
and income statement accounts in local functional currencies. These currencies
are translated to U.S. dollars using ending and quarterly average exchange
rates, respectively. The resulting translation adjustments are reported in a
separate component of stockholders' equity.
 
Recognition of Premium Revenues and Related Expenses
 
Group insurance premiums are recognized as income over the period to which the
premiums relate. Individual disability premiums are recognized as income when
due. Benefits and expenses are matched with earned premiums to result in
recognition of profits over the life of the contracts. This association is
accomplished by recording a provision for future policy benefits and unpaid
claims and claim expenses and by amortizing deferred policy acquisition costs.
 
For retirement and universal life products, premium and other policy fee
revenue consist of charges for the cost of insurance, policy administration
and surrenders assessed during the period. Charges related to services to be
performed in the future are deferred until earned. The amounts received in
excess of premium and fees are recorded as deposits and included in other
policyholder funds in the Balance Sheets. Benefits and expenses include
benefit claims in excess of related account balances, interest credited at
various rates and amortization of deferred policy acquisition costs.
 
Reinsurance
 
UNUM America is involved in both the cession and assumption of reinsurance
with other companies. Risks are reinsured with other companies to reduce UNUM
America's exposure to large losses and permit recovery of a portion of direct
losses. UNUM America remains liable to the insured for the payment of policy
benefits if the reinsurers cannot meet their obligations under the reinsurance
agreements. Deferred policy acquisition costs, premiums, benefits and expenses
are stated net of reinsurance ceded to other companies. UNUM America

evaluates the financial condition of its reinsurers and monitors
concentrations of credit risk to minimize exposure to significant losses from
reinsurer insolvencies.
 
Changes in Accounting Estimates
 
During fourth quarter 1997, certain reinsurance pools managed by UNUM
Corporation's wholly-owned subsidiary, Duncanson & Holt Inc., received new
claim information from ceding insurance enterprises about certain older pool
years and completed an analysis of recent claims experience deterioration. As
a result of these factors, certain pools have strengthened claim reserves. The
impact to UNUM America in fourth quarter 1997 from these pool claim reserve
increases was a $6.7 million increase in benefits to policyholders reported in
the Special Risk Insurance segment, reducing net income by $4.4 million in the
Statement of Income.
 
During 1995, UNUM America sold virtually all of its common stock portfolio.
The sale of the common stock portfolio, which partially supported certain
disability reserves, and the reinvestment of the proceeds primarily in
investment grade fixed income assets at yields below the average portfolio
yield, resulted in lower reserve discount rates for certain disability
products reported in the Disability Insurance segment. This change in
accounting estimate to lower certain discount rates resulted in an increase of
$114.1 million to benefits to policyholders in the Statement of Income, and a
decrease to net income of $74.2 million.
 
During 1995, UNUM America increased group long term disability reserves for
incurred but not reported ("IBNR") claims, as reported in the Disability
Insurance segment. The increased IBNR reserves were based on management's
judgment that claims incurred but not yet reported would reflect increased
levels of claims incidence and severity. This change in accounting estimate
resulted in an increase to benefits to policyholders in the Statement of
Income of $34.3 million, and a decrease to net income of $22.3 million.
 
During 1995, UNUM America increased reserves for unpaid claims related to the
association group disability business by $15.0 million to reflect management's
expectations of slower than expected claim recoveries. This change in
accounting estimate, which was reported in the Disability Insurance segment,
decreased net income by $9.8 million.
 
Accounting Pronouncements Adopted
 
Effective December 31, 1997, UNUM America adopted Financial Accounting
Standards ("FAS") No. 129, "Disclosures of Information About Capital
Structure," which consolidates disclosure requirements related to the type and
nature of securities contained in an entity's capital structure. FAS 129 does
not add to or change any of UNUM America's disclosures.
 
Effective January 1, 1997, UNUM America adopted FAS No. 125, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities," which established accounting and reporting standards for
transfers and servicing of financial assets and extinguishments of
liabilities. The statement provides guidance for recognition or derecognition
of assets and liabilities, focusing on the concepts of control and
extinguishment. The adoption of FAS 125 did not have a material effect on UNUM
America's results of operations or financial position.
 
Effective January 1, 1996, UNUM America adopted FAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of," which established accounting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles to be disposed of. The adoption of FAS 121 did not have a material
effect on UNUM America's results of operations or financial position.
 
New Accounting Pronouncements
 
In June 1997, the Financial Accounting Standards Board ("FASB") issued FAS No.
130, "Reporting Comprehensive Income," which establishes standards for
reporting and display of comprehensive income and its
 
                                      F-9

components in a financial statement with the same prominence as other
financial statements. Comprehensive income is defined as net income adjusted
for changes in stockholders' equity resulting from events other than net
income or transactions related to an entity's capital instruments. UNUM
America is required to adopt FAS 130 effective January 1, 1998, with
reclassification of financial statements for earlier years required.
 
  In June 1997, the FASB issued FAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which establishes standards for reporting
information about operating segments. Generally, FAS 131 requires that
financial information be reported on the basis that is used internally for
evaluating performance. UNUM America is required to adopt FAS 131 effective
January 1, 1998, and comparative information for earlier years must be
restated. This statement does not need to be applied to interim financial
statements in the initial year of application. UNUM America is currently
considering what impact, if any, FAS 131 will have on its current segment
reporting structure.
 
In February 1998, the FASB issued FAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits," which revises current disclosure
requirements for employers' pension and other retiree benefits. FAS 132 does
not change the measurement or recognition of pension or other postretirement
benefit plans. UNUM America is required to adopt FAS 132 effective January 1,
1998, with restatement of disclosures for earlier years required.
 
In December 1997, the Accounting Standards Executive Committee issued
Statement of Position ("SOP") 97-3, "Accounting by Insurance and Other
Enterprises for Insurance-Related Assessments," which provides guidance on
accounting for insurance-related assessments. UNUM America is required to
adopt SOP 97-3 effective January 1, 1999. Previously issued financial
statements should not be restated unless the SOP is adopted prior to the
effective date and during an interim period. The adoption of SOP 97-3 is not
expected to have a material impact on UNUM America's results of operations,
liquidity or financial position.

UNUM America's fixed maturities are reported at fair value as a result of
being classified as available for sale. Accordingly, the related liability for
unpaid claims and claims expenses is adjusted to reflect the changes that
would have been necessary if the related fixed maturities were sold at their
fair value and the proceeds were reinvested at current yields. At December 31,
1997, and 1996, the unrealized gain on available for sale fixed maturities was
$275.9 million and $202.3 million, respectively, and the related unpaid claims
adjustment was $169.1 million and $119.4 million, respectively.
 
The marketable securities held in trust relate to the individual disability
reinsurance agreement (see Note 6 "Reinsurance"). Changes in fair value of the
assets and the related adjustment to unpaid claims are reflected in the equity
section of UNUM America's Balance Sheet.

NOTE 4. RESERVES
 
Reserves for Future Policy Benefits
 
Reserves for future policy benefits are calculated by the net-level premium
method and are based on UNUM America's expected morbidity, mortality and
interest rate assumptions at the time a policy is issued. These reserves
represent the portion of premiums received, accumulated with interest and held
to provide for claims that have not yet been incurred. The reserve assumptions
are periodically reviewed and compared with actual experience and may be
revised if it is determined that future expected experience is different from
the reserve assumptions. Reserves for group insurance policies consist
primarily of unearned premiums. The interest rates used in the calculation of
reserves for future policy benefits at December 31, 1997, and 1996,
principally ranged from 5.0% to 9.5%. Certain reserve calculations are based
on variable interest rates within these ranges.
 
Reserves for Unpaid Claims and Claim Expenses
 
Unpaid claims and claim expense reserves represent the amount estimated to
fund claims that have been reported but not settled and claims incurred but
not reported. Reserves for unpaid claims are estimated based on UNUM America's
historical experience and other actuarial assumptions that consider the
effects of current developments, anticipated trends, risk management programs
and renewal actions. Many factors affect actuarial calculations of claim
reserves, including but not limited to interest rates and current and
anticipated incidence rates, recovery rates, and economic and societal
conditions. Management periodically performs a review of reserve estimates and
assumptions. If management determines reserve assumptions need to be updated,
any resulting adjustment to reserves are reflected in current results. Given
that insurance products contain inherent risks and uncertainties, the ultimate
liability may be more or less than such estimates indicate.
 
The interest rates used in the calculation of disability claims reserves at
December 31, 1997, and 1996, were principally as follows:
 
<TABLE>

                                                         1997          1996

Group long term disability..........................         7.84%         7.88%
Individual disability............................... 7.0% to 9.50% 7.0% to 9.50%
</TABLE>
 
The interest rate used to discount the disability reserves is a composite of
the yields on assets specifically identified with each block of business. The
discount rate may decline further depending on the interest rate environment.
UNUM America periodically adjusts prices on both existing and new business in
an effort to mitigate the impact of the current interest rate environment.
 
For other accident and health business, reserves are based on projections of
historical claims run-out patterns.

</TABLE>
 
The additional reserves for amounts incurred related to prior years were
primarily the result of interest accrued on reserves, changes in reserve
estimates and assumptions of interest rates, morbidity, mortality and expense
costs. Due to the long term claims payment pattern of some of UNUM America's
businesses, certain reserves, particularly disability, are discounted for
interest.
 
The effects of changes in reserve estimates and assumptions were more
significant in 1995, primarily as a result of increased reserves from lower
discount rates for certain disability products following the sale of the
common stock portfolio, and adjustments to strengthen certain disability
reserves in 1995.
 
Beginning in 1995, as explained in Note 2 "Investments," unpaid claims are
adjusted to reflect changes that would have been necessary if the unrealized
gains and losses had been realized. Where applicable, UNUM America has
reflected those adjustments in the liability balances with corresponding
credits or charges, net of related deferred taxes, reported as a component of
unrealized gains in stockholders' equity.
 
NOTE 5. SALE OF TAX-SHELTERED ANNUITY BUSINESS
 
On October 1, 1996, UNUM America closed the sale of its group tax-sheltered
annuity ("TSA") businesses to The Lincoln National Life Insurance Company
("Lincoln"), a subsidiary of Lincoln National Corporation. The sale involved
approximately 1,650 group contractholders and assets under management of
approximately $3.2 billion. The contracts were initially reinsured on an
indemnity basis. Upon consent of the TSA contractholders and participants, the
contracts are considered reinsured on an assumption basis, legally releasing
UNUM America from future contractual obligation to the respective
contractholders and participants.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
To effect the sale of the TSA business, UNUM America transferred into a trust
account held for the benefit of Lincoln approximately $2,641 million of
assets. UNUM America has recorded a deposit asset in its Balance Sheet
representing the assets which support the TSA contracts of those
contractholders and participants that have not given consent for assumption
reinsurance. At December 31, 1997, the deposit asset related to the TSA
transaction was approximately $252 million.
 
The sale resulted in a deferred pretax gain of $77.2 million, which is being
recognized in income in proportion to contractholder and participant consents
for assumption reinsurance. Through December 31, 1997, consent for assumption
reinsurance has been provided by TSA contractholders and participants owning
approximately 92% of assets under management.
 
Historical results of the TSA business included in UNUM America's Statements
of Income were as follows:

NOTE 6. REINSURANCE
 
UNUM America is involved in both the cession and assumption of reinsurance
with other companies.
 
On October 23, 1996, UNUM America announced the execution of a definitive
reinsurance agreement between UNUM America and Centre Life Reinsurance Limited
("Centre Re"), a Bermuda-based reinsurance specialist, for reinsurance
coverage of the active life reserves of UNUM America's existing United States
non-cancelable individual disability ("ID") block of business. This agreement
does not reinsure any claims incurred prior to January 1, 1996. The agreement
follows UNUM America's announcement in late 1994 that it would no longer
market the non-cancelable form of ID coverage in the United States.
 
The agreement is a finite reinsurance arrangement that transfers liabilities
to Centre Re based on the level of statutory reserves. Centre Re has an
obligation to absorb losses within a defined risk layer, while UNUM America
must fund an experience layer representing the difference between reserves
related to the reinsured block, based on generally accepted accounting
principles ("GAAP"), and the bottom of Centre Re's defined risk layer. Within
this experience layer, UNUM America retains the earnings risk related to
potential adverse experience from the reinsured block. Under the agreement,
UNUM America funds a trust account, initially established in late 1996, with
assets equal to the amount of GAAP reserves related to the reinsured block
plus the amount of its experience layer. The value of UNUM America's
experience layer increases or decreases in conjunction with the underlying
operating results of the reinsured block. Additionally, realized gains or
losses on assets sold, and unrealized gains or losses on marketable securities
held in the trust and the related claim reserves, affect the valuation of the
experience layer. UNUM America reflects the carrying value of the experience
layer in its Balance Sheet as a deposit asset, which at December 31, 1997,
totaled approximately $347 million. Changes in the experience layer derived
from the underlying operating results of the reinsured block are reflected in
fees and other income and realized gains or losses from sales of trust assets
are reflected as realized investment gains (losses) in UNUM America's
Statement of Income. Changes in the experience layer resulting from unrealized
gains or losses on marketable securities held in the trust and the related
claim reserves are reflected as unrealized gains or losses in the equity
section of UNUM America's Balance Sheet.

In fourth quarter 1996, UNUM America recognized a pretax charge of $49.7
million, which represents the present value of the anticipated minimum amount
of fees to be paid to Centre Re under the agreement. UNUM has the right, but
no obligation, to recapture the business after five years, with certain
penalties.

For the years ended December 31, 1997, 1996 and 1995, recoveries recognized
under reinsurance agreements offset benefits to policyholders by $270.9
million, $65.7 million and $50.7 million, respectively.
 
NOTE 7. BUSINESS RESTRUCTURING AND OTHER CHARGES
 
Business Restructuring
 
Charges of $7.2 million and $8.4 million were recorded in 1996 and 1995,
respectively. The charge in 1996 was related to the merger of Commercial Life
into UNUM America. The charge in 1995 related to the acceleration of
organizational changes within UNUM America and the decision to discontinue the
individual disability non-cancelable product. Partially offsetting the charge
recorded in 1995 was a curtailment gain, related to workforce reductions in
UNUM Corporation's noncontributory defined benefit pension plan, which
includes UNUM America.
 
Intangible Asset Write-offs and Future Loss Reserves
 
In connection with the merger of Commercial Life into UNUM America, the sale
of the tax-sheltered annuity business (see Note 5 "Sale of Tax-Sheltered
Annuity Business"), as well as UNUM America's continued efforts to strengthen
its focus on its core products, the company initiated a review of certain
products, which resulted in the recognition of pretax charges totaling $37.5
million during 1996. These charges reduced income before income taxes by $13.1
million in the Disability Insurance segment, $9.4 million in the Special Risk
Insurance segment, and $15.0 million in the Retirement Products segment. On an
after-tax basis the charges reduced net income by $25.1 million.
 
The total charges of $37.5 million included the write-off of certain
intangible assets, primarily deferred acquisition costs, totaling $12.7
million. These intangible assets were deemed unrecoverable primarily due to
the expectation of continued losses in the association group disability
business. Additionally, in conjunction with the completion of a review of UNUM
America's discontinued product portfolio, a $22.4 million charge was taken to
establish a reserve for the present value of expected future losses on certain
discontinued products. Losses for these products are charged to the reserve at
the time realized. The products incorporated in the charge consist of certain
discontinued special risk, retirement and medical products.

NOTE 8. EMPLOYEE BENEFIT AND INCENTIVE PLANS
 
Pension Plans
 
At December 31, 1997, UNUM Corporation had a noncontributory defined benefit
pension plan ("Lifecycle Plan") covering substantially all domestic employees,
including employees of UNUM America. The Lifecycle Plan provides benefits
based on the employee's age at retirement, years of service and earnings
during the highest five of the last ten years of employment. UNUM America
funds its pension plan in accordance with the requirements of the Employee
Retirement Income Security Act of 1974, as amended. Beginning in 1997, plan
assets were transferred from UNUM America's separate accounts into a trust for
the exclusive benefit of plan participants, and includes 448,784 shares of
UNUM Corporation common stock.
 
In 1997, UNUM Corporation changed the measurement date for the valuation of
its pension plan and postretirement benefit plan assets and actuarially
determined obligations from December 31, to September 30. The change in
measurement date had no effect on 1997 or prior years' net pension and
periodic postretirement benefit costs.
 
Postretirement Health Care and Life Insurance Benefits
 
UNUM America provides certain health care and life insurance benefits for
retired employees and covered dependents. Substantially all domestic employees
of UNUM America may become eligible for these benefits if they meet minimum
age and service requirements, if they are eligible for retirement benefits and
if they agree to contribute a portion of the cost. UNUM America has the right
to modify or terminate these benefits. The underlying plans are not currently
funded. The cost of these plans was $3.0 million, $8.0 million and $8.5
million for the years ended December 31, 1997, 1996 and 1995, respectively. At
December 31, 1997, and 1996 the liability associated with these plans was
$71.3 million and $64.8 million, respectively.
 
Retirement Savings Plans
 
UNUM America participates in UNUM Corporation's Retirement Savings Plan.
Effective January 1, 1997, UNUM Corporation introduced a single retirement
savings plan for all domestic employees who meet the eligibility requirement
of one year of service. Dependent upon the employee's annual earnings,
eligible employees may contribute up to 15% of their annual compensation,
including incentive payouts. UNUM America matches 100% of the employee's
contribution up to 3% of the employee's compensation, plus 50% of the
employee's contribution on the next 2% of the employee's compensation, to a
maximum of 4%. Employees become 100% vested immediately upon becoming eligible
to participate. Expense for this plan and the former plans amounted to $7.3
million, $5.6 million and $6.3 million in 1997, 1996 and 1995, respectively.
 
Annual Incentive Plans
 
UNUM America has several annual incentive plans for certain employees and
executive officers that provide additional compensation based on achievement
of predetermined annual corporate and affiliate financial and non-financial
goals. In 1997, 1996 and 1995, expense for these plans was $26.1 million,
$31.1 million and $14.7 million, respectively.
 
Stock Options
 
The 1996 Long-Term Stock Incentive Plan ("1996 Incentive Plan") provides for
granting options to officers, nonemployee directors of UNUM America, and key
employees to purchase UNUM Corporation common stock over ten years. The 1996
Incentive Plan also provides for granting to key officers restricted stock
awards whose vesting is contingent upon achieving prescribed financial
performance objectives or upon the grantee remaining in UNUM's employ for a
specified period of time. Options and restricted stock may be granted annually
at the discretion of the Committee.

The 1998 Goals Stock Option Plan provides for granting to all eligible
employees up to 300 options to purchase UNUM Corporation common stock. The
options will vest to the employee nine years from the date of grant. Vesting
may be accelerated to an earlier date at the discretion of the plan
administrator.
 
NOTE 9. DIVIDEND RESTRICTIONS
 
UNUM America is subject to various state insurance regulatory restrictions
that limit the maximum amount of dividends available from its United States
domiciled insurance subsidiaries without prior approval. The amount available
under current law for payment of dividends during 1998 to UNUM Corporation
from UNUM America without state insurance regulatory approval is approximately
$182 million. Dividends in excess of this amount may only be paid with state
insurance regulatory approval. The statutory capital and surplus of UNUM
America was approximately $946 million and $961 million, at December 31, 1997,
and 1996, respectively. The statutory net operating income, which excludes
realized investment gains and losses net of tax, of UNUM America was
approximately $182 million, $113 million and $227 million for 1997, 1996 and
1995, respectively. State insurance regulatory authorities prescribe statutory
accounting practices that differ in certain respects from generally accepted
accounting principles. The significant differences relate to deferred
acquisition costs, deferred income taxes, non-admitted asset balances,
required investment risk reserves and reserve calculation assumptions.

NOTE 11. FAIR VALUES OF FINANCIAL INSTRUMENTS
 
Fair values are based on quoted market prices, when available. In cases where
quoted market prices are not available, fair values are based on estimates
using present value or other valuation techniques. These valuation techniques
require management to develop a significant number of assumptions, including
discount rates and estimates of future cash flow. Derived fair value estimates
cannot be substantiated by comparison to independent markets or to disclosures
by other companies with similar financial instruments. These fair value
disclosures do not purport to be the amount that could be realized in
immediate settlement of the financial instrument.
 
The following table summarizes the carrying amounts and fair values of UNUM
America's financial instruments at December 31, 1997, and 1996:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
The following methods and assumptions were used in estimating fair value
disclosures for financial instruments:
 
Fixed Maturities Available for Sale: Fair values for fixed maturities are
based on quoted market prices, where available. If quoted market prices are
not available, fair values are estimated using values obtained from
independent pricing services or, in the case of private placements, are
estimated by discounting expected future cash flows using a current market
rate applicable to the yield, credit quality and maturity of the investments.
 
Equity Securities Available for Sale: Fair values for equity securities
available for sale are based on quoted market prices and are reported in the
Balance Sheets at these values.
 
Mortgage Loans: Fair values for mortgage loans are estimated based on
discounted cash flow analyses using interest rates currently being offered for
similar mortgage loans to borrowers with similar credit ratings and
maturities. Mortgage loans with similar characteristics are aggregated for
purposes of the calculations.
 
Policy Loans, Short-term Investments, Cash, Accrued Investment Income and
Deposit Assets: Fair values for these instruments approximate the carrying
amounts reported in the Balance Sheets.
 
Investment-type Insurance Contracts: Fair values for liabilities under
investment-type insurance contracts with defined maturities are estimated
using discounted cash flow calculations based on interest rates that would be
offered currently for similar contracts with maturities consistent with those
remaining for the contracts being valued. Fair values for liabilities under
investment-type insurance contracts with no defined maturities are the amounts
payable on demand after surrender charges at the balance sheet date.
 
The estimated fair values of liabilities under all insurance contracts
(investment-type and other than investment-type) are taken into consideration
in UNUM America's overall management of interest rate risk, which minimizes
exposure to changing interest rates through the matching of investment
maturities with amounts due under insurance contracts.
 
Individual Annuities and Supplementary Contracts not Involving Life
Contingencies: Fair values approximate the carrying amounts reported in other
policyholder funds in the Balance Sheets.

NOTE 12. DERIVATIVE FINANCIAL INSTRUMENTS
 
UNUM America periodically uses options, futures, and forward exchange
contracts which are common derivative financial instruments, to hedge certain
risks associated with anticipated purchases and sales of investments,
anticipated debt issuance and certain payments denominated in foreign
currencies, primarily Canadian dollars. These derivative financial instruments
are used to protect UNUM America from the effect of market fluctuations in
interest and exchange rates between the contract date and the date on which
the hedged transaction occurs.
 
In using these instruments, UNUM America is subject to the off-balance-sheet
credit risk that the counterparties of the transactions will fail to perform
as contracted. UNUM America manages this risk by only entering into contracts
with highly rated institutions and listed exchanges. UNUM America does not
hold or issue derivative financial instruments for the purpose of trading.
 
Historically, all positions UNUM America has taken in derivative contracts
have qualified for hedge accounting in accordance with the criteria
established by FAS 52, "Foreign Currency Translation," and FAS 80, "Accounting
for Futures Contracts." Upon entering a derivative contract, UNUM America uses
this criteria to evaluate the correlation of risk protection provided by a
derivative contract to the risk created by market fluctuations to ensure hedge
accounting is appropriate for the contract. Accordingly, gains or losses
related to qualifying hedges of firm commitments or anticipated transactions
involving investment purchases and debt issuance are deferred and recognized
as an adjustment to the carrying amount of the underlying asset or liability
when the hedged transaction occurs. Gains or losses related to qualifying
hedges of anticipated transactions involving the sale of investments are
deferred and recognized in income when the hedged transaction occurs. No gains
or losses related to qualifying hedges of anticipated transactions involving
payments denominated in foreign currencies are recorded if the hedged
transaction is likely to occur.
 
The amount of any deferred gains or losses on outstanding interest rate
futures contracts, which require daily cash settlement, are included in fixed
maturities in UNUM America's Balance Sheet. The fair values of any outstanding
forward exchange rate contracts and options which do not require daily cash
settlement, are not recognized in UNUM America's Balance Sheet.
 
Any resulting gains or losses from early termination of a derivative
designated as a hedge are deferred and recognized in income or as an
adjustment of the carrying amount of the underlying asset or liability when
the hedged transaction occurs. Any gains or losses that result when the
designated item is extinguished, such as maturity, sale, or termination, or
when the hedged transaction is no longer likely to occur, are included in
income in the period in which the extinguishment takes place or it is known
that the hedged anticipated transaction will not occur.
 
UNUM America had no open derivative financial instruments at December 31,
1997. UNUM America had open interest rate futures contracts at December 31,
1996, with notional amounts of $159.7 million to hedge anticipated sales of
investments in 1997. These futures contracts had a related net unrealized gain
of $1.3 million.
 
NOTE 13. LITIGATION
 
In the normal course of its business operations, UNUM America is involved in
litigation from time to time with claimants, beneficiaries and others, and a
number of lawsuits were pending at December 31, 1997. In some instances, these
proceedings include claims for punitive damages and similar types of relief in
unspecified or substantial amounts, in addition to amounts for alleged
contractual liability or other compensatory damages. In the opinion of
management, the ultimate liability, if any, arising from this litigation is
not expected to have a material adverse effect on the financial position,
operating results or liquidity of UNUM America.
 
On December 29, 1993, UNUM America filed a suit in the United States District
Court for the District of Maine, seeking a federal income tax refund. The suit
was based on a claim for a deduction in certain prior tax years for
 
                                     F-22

$652 million in cash and stock distributed to policyholders in connection with
the 1986 conversion of Union Mutual Life Insurance Company to a stock company.
UNUM America has fully paid, and provided for in prior years' financial
statements, the tax at issue in this litigation. On May 23, 1996, the District
Court issued its decision that the distribution in question was not a
deductible expenditure. On December 2, 1997, the United States Court of
Appeals affirmed the decision of the District Court denying UNUM America's
claim for refund. UNUM America is currently considering whether to request
that the United States Supreme Court review the decision of the United States
Court of Appeals.
 
NOTE 14. AFFILIATED COMPANIES AND RELATED PARTY TRANSACTIONS
 
UNUM America provides management and administrative services to affiliates,
which are wholly-owned by UNUM Corporation. UNUM America allocates,
principally at cost, the related expenses based on direct association whenever
possible. If the expenses cannot be readily associated, the costs are
allocated based on ratios of the relative time spent, extent of usage or
varying volume of work performed.
 
On December 31, 1997, UNUM America entered into a 100% indemnity coinsurance
agreement with UNUM International Limited ("UNUM International"), an
affiliated company organized under the laws of the Islands of Bermuda. Under
the agreement, UNUM America transferred group long term disability ("group
LTD") claim reserves to UNUM International with respect to disabilities which
occurred prior to December 31, 1992. UNUM America will continue to transfer
group LTD claim reserves to UNUM International each quarter with respect to
disabilities which occurred during the quarter ending nineteen quarters prior
to the ceding date. Either party may terminate this agreement as to risks not
yet ceded upon ninety days notice in writing to the other party. At December
31, 1997, $56.5 million of the claim liabilities were ceded to UNUM
International under this agreement.
 
On February 28, 1995, UNUM Corporation borrowed $100 million under its
revolving credit facility, which was infused into UNUM America in exchange for
surplus debentures which matured on August 31, 1996, and accrued interest at
5.66% annually. Repayment of principal and interest on the surplus debentures
was subject to state insurance regulatory approval. On December 31, 1995, UNUM
America repaid $50 million of the surplus debentures, plus accrued interest of
$5.5 million to UNUM Corporation. In April, 1996, UNUM America received
approval from the Maine Bureau of Insurance to repay the remaining $50 million
in surplus debentures. The company repaid the principal and interest in April
1996.
 
During December 1993, UNUM America loaned $60 million to UNUM Corporation.
These notes matured on December 20, 1996, and accrued interest at 5.66%
annually. On December 31, 1995, UNUM Corporation repaid $50 million of these
notes to UNUM America. UNUM Corporation repaid the $10 million outstanding
note to UNUM America in April 1996.

Item 27.       Number of Contractholders

        
As of March 31, 1998, Registrant had 53 Contractholders.          

Item 28.       Indemnification

Under the Participation Agreements entered into between UNUM/America and the
Dreyfus Life & Annuity Index Fund, Inc., Dreyfus Variable Investment Fund and
Dreyfus Corporation, Variable Insurance Products Funds I and II and Fidelity
Distributors Corporation, Twentieth Century Management Company, Acacia Capital
Corporation, and T. Rowe Price (the "Funds"), UNUM/America and its directors,
officers, employees, agents and control persons have been indemnified by the
Fund against any losses, claims or liabilities that arise out of any untrue
statement or alleged untrue statement or omission of a material fact in the
Funds' registration statements, prospectuses or sales literature.  In addition,
the Funds will indemnify UNUM/America against any liability, loss, damages,
costs or expenses which UNUM/America may incur as a result of the Funds'
incorrect calculations, incorrect reporting and/or untimely reporting of the
Funds' net asset values, dividend rates or capital gain distribution rates.

UNUM/America's by-laws provide that UNUM/America "may indemnify any person made
or threatened to be made a party of any action or proceeding, including an
action by or in the right of any other corporation of any type or kind, domestic
or foreign, which any director, officer or employee of the Corporation served in
any capacity at the request of the Corporation, by reason of the fact that he,
his testator or intestate, was a director, officer or employee of the
Corporation or served such other corporation in any capacity, against judgments,
fines, amounts paid in settlement and reasonable expenses, including attorneys'
fees, actually and necessarily incurred as a result of such action or
proceeding, or any appeal therein, if such director, officer, or employee acted,
in good faith, for a purpose which he or she reasonably believed to be in the
best interests of the corporation."

Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
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 the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant 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.

                          ARTICLE III - CONTRIBUTIONS

3.1    INITIAL CONTRIBUTION:  The initial Contribution for a Participant will be
       credited to the Participant's Account no later than two (2) Business Days

       shall notify UNUM in writing in a form acceptable to UNUM or by telephone
       in accordance with procedures published by UNUM of such changes.

3.3    PAYMENT OF SUBSEQUENT CONTRIBUTIONS:  You shall forward Contributions to
       UNUM specifying the amount being contributed on behalf of each
       Participant. You shall forward such Contributions and provide such
       allocation information in accordance with procedures established by UNUM.
       The Contributions shall be allocated among the Guaranteed Interest
       Division and each Sub-Account in accordance with the percentage
       information provided by the Participant subject to the terms of the Plan.

3.4    CHARACTERIZATION OF TRANSFER CONTRIBUTIONS:  For all Contributions
       transferred from another Contract, UNUM must be provided with the
       following information in a form acceptable to UNUM:

       (a)  The source of the Contributions transferred (e.g., salary reduction,
            employer match or post-tax Contributions). UNUM will record all such
            transferred amounts where no source information is provided as
            salary reduction Contributions.

       (b)  Identification of Contributions transferred as Contributions made or
            earnings credited:

            (i)    prior to January 1, 1987;
            (ii)   during 1987 and 1988; or
            (iii)  subsequent to December 31, 1988.

            Amounts not so identified will be treated as attributable to period
            (iii) for purposes of Sections 7.4 and 7.5.

3.5    MAXIMUM CONTRIBUTION:  Total and overall limitations on Contributions in
       a calendar year for a Participant are subject to the limits imposed under
       Sections 402(g), 403(b) and 415 of the Internal Revenue Code of 1986 (the
       Code), as it may be amended from time to time. UNUM assumes no
       responsibility for monitoring these limits for a Participant.

3.6    VALUATION:  A Guaranteed Interest Division Contribution will be allocated
       as of the Business Day that UNUM receives the Contribution and UNUM will
       credit interest beginning with the next calendar day following the
       Business Day that UNUM receives the Contribution.

                                       8
<PAGE>
 
       For a Variable Investment Division Sub-Account Contribution, UNUM will
       credit a Participant's Account with the number of Accumulation Units for
       each Sub-Account selected by the Participant with the number of
       Accumulation Units equal to the Contribution Amount divided by the
       Accumulation Unit Value which is next computed following UNUM's receipt
       of the Contribution.

3.7    ANNUAL ADMINISTRATION CHARGE:  UNUM will deduct the amount stated in
       Section 1.5 from each Participant's Account each year on the last
       Business Day of the month in which his Participation Anniversary occurs
       unless the Contractholder pays the charge in a single payment. If the
       Participant's Account balance is less than this amount on that day, UNUM
       will deduct the entire balance from his Account.

       When a Total Withdrawal of a Participant's Account, as defined in Section
       7.2, occurs on a date other than the last Business Day of the month in
       which his Participation Anniversary occurs, UNUM will first deduct the
       amount stated in Section 1.5 from his Participant's Account.

       ANNUAL ADMINISTRATION CHARGE:  UNUM will deduct the amount stated in
       Section 1.5 on a pro-rata basis from the Participant's Variable
       Investment Division Account balance each year on the last Business Day of
       the month in which his Participation Anniversary occurs unless the
       Contractholder pays the charge in a single payment. If the Participant's
       Variable Investment Division Account balance is less than this amount on
       that day, UNUM will deduct the entire balance from his Variable
       Investment Division Account.

       When a Participant requests, on a date other than the last Business Day
       of the month in which his Participation Anniversary occurs,

          (a)  a withdrawal, or
          (b)  a transfer,

       from the Variable Investment Division, which would leave a remaining
       balance of less than the Annual Administration Charge defined in Section
       1.5, UNUM will first deduct the amount stated in Section 1.5 from the
       Participant's Variable Investment Division Account balance prior to the
       Withdrawal or Transfer.

3.8    UNALLOCATED CONTRIBUTION:  If a properly completed enrollment form has
       not been received for a Participant, UNUM will deposit such Contributions
       to the Pending Allocation Account as described in ARTICLE II-
       DEFINITIONS, unless such Contributions are designated to another Account
       in accordance with the Plan.

       UNUM will follow up with the Contractholder monthly for a period of
       ninety (90) days for enrollment information for Participants with
       deposits in the Pending Allocation Account.

       Within two (2) business days of receipt of a completed enrollment form,
       the Participant's Account balance in the Pending Allocation Account will
       be transferred to the Divisions and/or Sub-Accounts according to the
       percentages requested by the Participant. When the

                                       9
<PAGE>
 
       completed enrollment form is received, the Participation Date will be the
       date on which the first Contribution on behalf of the Participant was
       deposited into the Pending Allocation Account.

       If an enrollment form is not received after the ninety (90) day notice, a
       Participant's Account balance in the Pending Allocation Account will be
       refunded to the Contractholder within one hundred five (105) days of the
       date of the initial Contribution. Contributions received after a refund
       while there is still no allocation information, will be deposited to the
       Pending Allocation Account.

       The Pending Allocation Account will only be used for the purpose
       mentioned above; Participants may not direct a portion of their
       Contributions to this Account. Contributions deposited in the Pending
       Allocation Account will not be afforded the same rights as Contributions
       under this Contract. The following Articles and/or Sections under this
       Contract will not be applicable: (i) Section 3.7 ANNUAL ADMINISTRATION
       CHARGE, (ii) ARTICLE VI - TRANSFERS BETWEEN DIVISION AND SUB-ACCOUNTS,
       (iii) ARTICLE VII - WITHDRAWALS AND DISTRIBUTIONS, (iv) ARTICLE IX -

                   ARTICLE IV - GUARANTEED INTEREST DIVISION

4.1    PARTICIPANT'S ACCOUNT BALANCE IN GUARANTEED INTEREST DIVISION:  The
       dollar value of a Participant's Account balance in the Guaranteed
       Interest Division as of a date will be equal to the sum of:

       (a)  Contributions allocated, on behalf of the Participant, to the
            Guaranteed Interest Division on or prior to that date, and

       (b)  Amounts transferred, on behalf of the Participant, to the Guaranteed
            Interest Division from the Variable Investment Division on or prior
            to that date, less any;

       (c)  Gross Withdrawal Amounts from the Guaranteed Interest Division, on
            behalf of the Participant, on or prior to that date; and

       (d)  Amounts transferred, on behalf of the Participant, to the Variable
            Investment Division on or prior to that date; and

       (e)  Applicable charges to the Participant's Account on or prior to that
            date; and

       (f)  Annuity Conversion Amounts, on behalf of the Participant, on or
            prior to that date, plus any;

       (g)  Interest credited to the Participant's Account balance in the
            Guaranteed Interest Division on or prior to that date.

4.2    INTEREST:  UNUM will credit interest each day to the portion of the
       Participant's Account balance in the Guaranteed Interest Division, using
       the previous day's ending balance. The rate of interest credited each
       day, if compounded for three hundred sixty-five (365) days, yields the
       annual interest rate in effect for the day.

       UNUM will declare in advance a guaranteed interest rate which will be
       effective for all amounts in the Participant's Account balance in the
       Guaranteed Interest Division during the designated year. This rate will
       never be less than three percent (3%). However, this minimum rate will
       not be considered for purposes of Section 10.6 (EFFECT OF LOAN ON
       PARTICIPANT'S ACCOUNT) under this Contract.

       UNUM may also declare in advance separate interest rate guarantees which
       are in excess of the guaranteed interest rate for some or all of the
       Participant's Account balance in the Guaranteed Interest Division for
       specific period(s) during the designated year.

                    ARTICLE V - VARIABLE INVESTMENT DIVISION

5.1    PARTICIPANT'S ACCOUNT BALANCE IN THE VARIABLE INVESTMENT DIVISION:
       The Participant's Account balance in the Variable Investment Division is
       equal to the sum of the dollar value of a Participant's Account balance
       in each Sub-Account as of the end of a Valuation Period which will be
       equal to the product of:

       (a)  The Participant's number of Accumulation Units as of the end of that
            Valuation Period; times

       (b)  The Accumulation Unit Value as of the end of that Valuation Period.

5.2    ACCUMULATION UNITS:  The number of Accumulation Units a Participant has
       in a Sub-Account as of the end of any Valuation Period is the number of
       Accumulation Units the Participant had in that Sub-Account as of the end
       of the preceding Valuation Period; plus

       (a)  The number of Accumulation Units attributable to amounts deposited
            to or transferred to that Sub-Account during the current Valuation
            Period; minus

       (b)  The number of Accumulation Units attributable to amounts transferred
            from, converted to an annuity, removed as a charge, paid as a death
            benefit, or withdrawn from that Sub-Account during the current
            Valuation Period.

5.3    ACCUMULATION UNIT VALUE:  The Accumulation Unit Value for each Sub-
       Account was set initially at ten dollars ($10), except for the Index
       Account which was set at nine and nine hundred six one thousands
       ($9.9060) of a dollar. Subsequent Accumulation Unit Values are determined
       by multiplying;

       (a)  The Net Investment Factor for the current Valuation Period by;

       (b)  The Accumulation Unit Value as of the end of the immediately
            preceding Valuation Period.

5.4    NET INVESTMENT FACTOR:  The Net Investment Factor is used to measure the
       investment experience of a Sub-Account net of the Mortality and Expense
       Risk Charge as defined in Section 5.5. The Net Investment Factor for a
       Valuation Period is equal to (a) divided by (b) with the result
       multiplied by (c) and adjusted by the amount per share of any taxes which
       are incurred by UNUM because of the existence of the Sub-Account;

                                       12
<PAGE>
 
       where (a) is;

            the net asset value per share of the underlying mutual fund held by
            the Sub-Account as of the end of the Valuation Period, plus;

            the amount per share of any dividend or capital gain distribution
            from the underlying mutual fund held by the Sub-Account during the
            Valuation Period,

       where (b) is;

            the net asset value per share of the underlying mutual fund held by
            the Sub-Account as of the end of the immediately preceding Valuation
            Period,

       where (c) is;

            one (1.00) minus the Annual Mortality and Expense Risk Charge shown
            in Section 1.6 to the n/365th power where n equals the number of
            calendar days since the immediately preceding Valuation Date.

5.5    MORTALITY AND EXPENSE RISK CHARGE:  This charge is imposed to compensate
       UNUM for its assumption of mortality and expense risks under this
       Contract. This charge is shown on an annualized basis in Section 1.6 and
       is deducted on a daily basis as described in Section 5.4. This charge may
       not be increased without the approval of a majority of all affected UNUM
       contractholders.

       Account.

       You or the Participant may make a transfer request by notifying UNUM in
       writing in a form acceptable to UNUM or by telephone in accordance with

                  ARTICLE VII - WITHDRAWALS AND DISTRIBUTIONS

7.1    WITHDRAWALS DURING THE ACCUMULATION PERIOD:  During the Accumulation
       Period, a Participant may withdraw from any or all Divisions, subject to
       the restrictions stated in Section 7.4, all or part of the Participant's
       Account balance in the Division or Sub-Accounts remaining after
       reductions for any applicable Annual Administration Charge (imposed on
       Total Withdrawals), Contingent Deferred Sales Charge (CDSC), premium
       taxes and outstanding loan, including the loan security thereon. Annuity
       Conversion Amounts are not considered withdrawals.

       All withdrawal requests must be submitted in a form acceptable to UNUM
       and must indicate the amount and the Division(s) from which the
       withdrawal is to be made.

       UNUM reserves the right to delay payment of Guaranteed Interest Division
       withdrawal amounts per Section 12.8.

7.2    TOTAL WITHDRAWALS:  A Total Withdrawal of a Participant's Account will
       occur when a Participant who has no outstanding loans

       (a)  requests the liquidation of his entire Account balance, or

       (b)  requests an amount such that the amount requested plus any CDSC as
            defined in Section 7.6 results in a remaining Participant's Account
            balance being less than the applicable Annual Administration Charge
            as defined in Section 1.5, in which case, the request is treated as
            if it were a request for liquidation of the Participant's entire
            Account balance.

       The Participant's Active Life Certificate must be surrendered to UNUM
       when a Total Withdrawal of a Participant's Account occurs.

       A Participant refund under the Free-look provisions of Section 12.17 is
       not considered a Total Withdrawal under this Article.

7.3    PARTIAL WITHDRAWALS:  A Partial Withdrawal of a Participant's Account
       will occur when:

       (a)  A Participant who has an outstanding loan makes a withdrawal; or

       (b)  A Participant who has no outstanding loans, requests an amount less
            than a total withdrawal.

            Subject to Title I of ERISA: Any portion of the Participant's
            Account balance that has been recorded by UNUM as a salary reduction
            contribution made and/or earnings credited prior to January 1, 1989,
            (including transferred amounts recorded as such pursuant to Section
            3.4), may be withdrawn for any reason. Any portion of the
            Participant's Account balance that has been recorded by UNUM as a

            December 31, 1988, (including transferred amounts recorded as such
            pursuant to Section 3.4), are subject to the withdrawal restrictions
            stated in Section 403(b) of the Code. Participants must certify to
            UNUM (and provide supporting information, if requested), that an
            event permitting withdrawal has occurred and that UNUM may rely on

7.5    MINIMUM DISTRIBUTION REQUIREMENTS FOR SECTION 403(b) PLANS:  Section
       403(b)(10) of the Code and regulations thereunder require that
       distributions be made from this Contract in a manner which satisfies
       requirements similar to the requirements of Section 401(a)(9) including
       the incidental death benefit requirements of Section 401(a)(9)(G).

       (1)  Section 401(a)(9) requires that:

       (2)  A Participant may choose to have the Participant's Account
            distributed in one of the following manners:

            (a)  As a lump sum payment;

<PAGE>
 
            (c)  As an annual distribution where the amount distributed each
                 calendar year is at least an amount equal to the quotient
                 obtained by dividing: (a) the amount of the Participant's
                 Account required to be distributed as of December 31 of the

                 the Participant, or the life expectancy of the Participant and
                 the Beneficiary; or

            other withdrawal has been made in that
            calendar year

       (b)  For all other amounts subject to a CDSC,
            the CDSC will equal                                   6%

       UNUM requires reasonable proof necessary to verify that the withdrawal
       meets the conditions described above in Section 7.6(a) and such proof
       must be submitted with the withdrawal request. If You or the Participant
       do not furnish the proof requested by UNUM, the CDSC stated in Section
       7.6(b) shall apply.

       The CDSC on any withdrawal may be reduced or eliminated but only to the
       extent that UNUM anticipates that it will incur lower sales expenses or
       perform fewer sales services due to economies arising from (i) the size
       of the particular group, (ii) an existing relationship with the
       Contractholder, (iii) the utilization of mass enrollment procedures, or
       (iv) the performance of sales functions by the Contractholder or an
       employee organization which UNUM would otherwise be required to perform.

       In no event will the CDSC, when added to any CDSC previously imposed due
       to a Participant withdrawal, exceed eight and one-half percent (8.5%) of
       the cumulative Contributions to a Participant's Account.

7.7    SYSTEMATIC WITHDRAWAL OPTION:  Any Participant who: (a) is at least age
       fifty-nine and one-half (59 1/2), or (b) is disabled and receiving Social
       Security disability benefits, or (c) is separated from service with the
       Contractholder may elect this option. A Participant must also have a
       vested Participant Account balance of at least ten thousand dollars
       $10,000) of pre-tax Contributions under this Contract at the date of the
       election.

       Amounts held for a spousal payee under a Qualified Domestic Relations
       Order (QDRO) shall be recognized as eligible for the Systematic
       Withdrawal Option. Any spousal payee who wishes to elect this
       distribution option must also meet the minimum ten thousand dollars
       ($10,000). Account balance requirement and either the age or disability
       requirement as discussed above.

       A Participant may elect to receive monthly, quarterly, semi-annual, or
       annual payments in a flat amount or payments on a monthly basis for an
       interest equivalency amount. An interest equivalency amount is an
       approximation of the interest earned between each payment period based
       upon the interest rate in effect at the beginning of each respective
       payment period. This amount will be determined by UNUM. (See Attachment I
       for illustration.) A Participant may change the frequency, payment type,
       or payment amount of his Systematic Withdrawal Option by submitting a
       request in writing on a form acceptable to UNUM. A Participant may make
       such a change only once during each calendar year.

       A Participant may at any time direct UNUM to cease payments under this
       option provided the request is made in writing. A Participant who chooses
       to stop receiving systematic withdrawals may not request that any
       systematic withdrawal payments begin again until the next calendar year.

                                       18
<PAGE>
 
       Systematic withdrawals shall be withdrawn from amounts allocated to the
       Guaranteed Interest Division of the Participant's Account balance. If the
       balance of the Guaranteed Interest Division is not sufficient to meet the
       payment amount requested, the Participant, in writing, may direct UNUM on
       a form acceptable to UNUM to transfer the appropriate amount to the
       Guaranteed Interest Division; otherwise, such payment will cease.

       UNUM will deduct the Systematic Withdrawal Set-Up Charge indicated in
       Section 1.10 from the Participant's Account balance each time a
       Systematic Withdrawal Option is established. The applicable CDSC, if any,
       will be assessed on each systematic withdrawal payment.

       Payments under this option shall stop upon the earliest of the following
       events.

       (a)  On the date of the Participant's death. A Beneficiary who is a
            spouse may elect this option by requesting it in writing on a form
            acceptable to UNUM, unless election of this form of benefit would
            violate any other requirements of this contract. The spousal
            Beneficiary must meet the ten thousand dollar ($10,000) minimum
            Account balance requirement prior to electing the Systematic
            Withdrawal Option; or

       (b)  When there is an insufficient Participant Account balance after
            deducting the applicable CDSC and Annual Administration Charge, if
            any, to pay the amount requested; or

       (c)  The Participant fails to meet the requirements of the Systematic
            Withdrawal Option as outlined above in the first (1st) paragraph of
            this Section.

       If a disabled or terminated Participant, who is currently receiving a
       Systematic Withdrawal Option payment, returns to service with the
       Contractholder, the Contractholder or Participant must notify UNUM in
       writing within thirty (30) days from the date of return to service. UNUM
       reserves the right to discontinue the Systematic Withdrawal Option
       payment under these circumstances.

       If a Participant wishes to exercise this option under another UNUM
       Annuity Contract, such request shall be considered separate from this
       Contract and shall follow the Systematic Withdrawal Option rules under
       that Annuity Contract, if permitted.

       UNUM may, at its option, discontinue the Systematic Withdrawal Option
       under this Contract at any time provided You are given at least thirty
       (30) days advance written notice.

7.8    DIRECT ROLLOVER OPTION:  Beginning January 1, 1993, a Participant or
       Beneficiary may elect this option for any distribution that qualifies as
       an Eligible Rollover Distribution as defined by Section 402(c) of the
       Internal Revenue Code and that meets all the following requirements:

       (1)  The distribution must be paid directly to either a single Individual
            Retirement Account or to a single Tax Deferred Annuity. The check,
            wire, or other form of remittance shall be made payable to the
            trustee, custodian, or financial institution sponsoring the

                                       19
<PAGE>
 
            Individual Retirement Account or Tax Deferred Annuity. The form of
            remittance will not be an instrument that can be negotiated by the
            Participant.

       (2)  The Participant must provide, in a form acceptable to UNUM, all
            information necessary to make the payment to an Individual
            Retirement Account or Tax Deferred Annuity.

       (3)  The Participant or Beneficiary may not revoke a request for payment
            under this option for any payment after UNUM has received a written
            request for a direct rollover.

                         ARTICLE VIII - DEATH BENEFITS

8.1    DEATH BENEFIT DURING THE ACCUMULATION PERIOD:  If death of the
       Participant occurs during the Accumulation Period, UNUM will pay the
       Beneficiary, if one is living, the greater of the following amounts:

       (a)  The Net Contributions, or

       (b)  The Participant's Account balance less any outstanding loan
            (including principal and due and accrued interest).

       UNUM will calculate the Death Benefit as of the end of the Valuation
       Period during which it receives both satisfactory notification of the
       Participant's death, pursuant to Section 8.2, and the election of a form
       of benefit pursuant to Section 8.3. If no election is made pursuant to
       Section 8.3 within sixty (60) days following UNUM's receipt of
       satisfactory notice of death, the Death Benefit will be calculated as of
       the end of the Valuation Period during which that sixtieth (60th) day
       occurs.

       If UNUM makes a withdrawal payment pursuant to a Participant request
       prior to receiving notice that the Participant has died, but subsequent
       to the Participant's death, UNUM will deduct that payment from each of
       (a) and (b) above in calculating the Death Benefit.

8.2    NOTIFICATION OF DEATH:  UNUM must be notified of a Participant's death no
       later than six (6) months from the Participant's date of death in order
       for the Beneficiary to receive the Death Benefit amount described in
       Section 8.1(a) above. Such notification must be in a form satisfactory to
       UNUM. Beneficiaries for whom notification of a Participant's death is
       received more than six (6) months after the Participant's date of death
       shall receive the Death Benefit amount described in Section 8.1(b) above.

8.3    PAYMENT OF DEATH BENEFIT:  Within sixty (60) calendar days after UNUM
       receives satisfactory notification of the Participant's death, the
       Beneficiary must make an election to have the Death Benefit applied in
       one of the following ways:

       (a)  As a lump sum payment to the Beneficiary; or

       (b)  Towards an annuity to be distributed in substantially equal
            installments over the life expectancy of the Beneficiary or a period
            certain not exceeding the life expectancy of the Beneficiary; or

       (c)  A combination of the above.

       A Beneficiary who does not make an election pursuant to this section
       within sixty (60) days after UNUM receives notification of the
       Participant's death will receive a lump sum payment calculated in
       accordance with Section 8.1(b) above.

                                       21
<PAGE>
 
       If the Beneficiary is someone other than the spouse of the deceased
       Participant, the Code provides that the Beneficiary may not elect an
       annuity which would commence later than December 31 of the calendar year
       following the calendar year of the Participant's death. If a non-spousal
       Beneficiary elects to receive payment in a single lump sum, such payment
       must be received no later than December 31 of the fourth (4th) calendar
       year following the calendar year of the Participant's death.

       If the Beneficiary is the surviving spouse of the deceased Participant,
       under the Code, distributions are not required to begin earlier than
       December 31 of the calendar year in which the Participant would have
       attained age seventy and one-half (70-1/2). If the surviving spouse dies
       before the date on which annuity distributions commence, then, for
       purposes of the Death Benefit, the surviving spouse shall be deemed to be
       the Participant.

       If there is no living named Beneficiary on file with UNUM at the time of
       a Participant's death, UNUM will pay the Death Benefit to the
       Participant's estate in a single lump sum upon receipt of satisfactory
       proof of the Participant's death, but not later than December 31 of the
       fourth (4th) calendar year following the calendar year of the
       Participant's death. Valuation of the Death Benefit shall occur as of the
       end of the Valuation Period during which due proof of the Participant's
       death is received by UNUM.

8.4    DEATH DURING THE ANNUITY PERIOD:  If the Annuitant dies during the
       Annuity Period, the Beneficiary, if any, or the Annuitant's estate will
       receive the amount payable, if any, according to the in-force annuity
       options. Any remaining Participant's Account balance will be paid in
       accordance with the provisions of this Article.

                         ARTICLE IX - PAYOUT ANNUITIES

9.1    ELECTION OF PAYOUT ANNUITY OPTION:  A Participant eligible to receive a
       distribution under the Code or a Beneficiary of a deceased Participant
       may notify UNUM in writing in a form acceptable to UNUM that the
       Participant or the Beneficiary is electing to convert all or part of the
       Participant's Account balance or Death Benefit to a Payout Annuity option
       available under this Contract. Upon being notified of such an election,
       UNUM shall calculate the amount to be converted to a Payout Annuity as
       either the Participant's Account balance, or a portion thereof, or the
       Death Benefit as of the initial Annuity Payment Calculation Date, as
       appropriate, less the charge for premium taxes, if any.

       If the Participant's Account balance or the Beneficiary's Death Benefit
       is less than two thousand dollars ($2,000) or if the amount of the first
       scheduled payment is less than twenty dollars ($20), UNUM may, at its
       option, cancel the Payout Annuity and pay the Participant or Beneficiary
       his entire Account balance or Death Benefit in a lump sum.

9.2    GUARANTEED ANNUITY:  The payment amount is determined by dividing the
       Annuitant's Annuity Conversion Amount in the Guaranteed Interest Division
       as of the initial Annuity Payment Calculation Date by the applicable
       Annuity Conversion Factor as defined in Section 9.4.

9.3    VARIABLE ANNUITY:  The initial payment amount of the Annuitant's Variable
       Annuity for each Sub-Account is determined by dividing his Annuity
       Conversion Amount in each Sub-Account as of the initial Annuity Payment
       Calculation Date by the applicable Annuity Conversion Factor as defined
       in Section 9.4.

       The amount of the Annuitant's subsequent Variable Annuity payment for
       each Sub-Account is determined by:

       (a)  Dividing the Annuitant's initial Variable Annuity payment amount by
            the Annuity Unit Value for that Sub-Account selected for his
            interest rate option as described in Section 9.4 as of his initial
            Annuity Payment Calculation Date; and

       (b)  Multiplying the resultant number of annuity units by the Annuity
            Unit Values for the Sub-Account selected for his interest rate
            option for his respective subsequent Annuity Payment Calculation
            Dates.

       The Annuity Unit Value for all Sub-Accounts for all interest rate options
       will initially be set at ten dollars ($10). Each subsequent Annuity Unit
       Value for a Sub-Account for an interest rate option is determined by:

            Dividing the Accumulation Unit Value for the Sub-Account as of the
            subsequent Annuity Payment Calculation Date (APCD) by the
            Accumulation Unit Value for the Sub-Account as of the immediately
            preceding APCD,

                                       23
<PAGE>
 
            Dividing the resultant factor by one (1.00) plus the interest rate
            option to the n/365 power where n is the number of days from the
            immediately preceding APCD to the subsequent APCD, and

            Multiplying this factor times the Annuity Unit Value as of the
            immediately preceding APCD.

9.4    BASIS OF ANNUITY CONVERSION FACTORS:

       (a)  Guaranteed Annuities - The maximum Annuity Conversion Factors that
            may be used by UNUM under this Contract are based on the1983
            Individual Annuity Mortality Table, set back four (4) years, and an
            interest rate of three percent (3.0%). From time to time, lower
            conversion factors may be used by UNUM. (Lowering the conversion
            factor will increase the amount of the annuity payment.)

       (b)  Variable Annuities - The Annuity Conversion Factors which are used
            to determine the initial payments are based on the1983 Individual
            Annuity Mortality Table, set back four (4) years, and an interest
            rate in an integral percentage ranging from zero to six percent (0
            to 6.00%) as selected by the Annuitant.

9.5    PAYOUT ANNUITY OPTIONS:  The following Payout Annuity options are
       available:

       (a)  Life
       (b)  Life with payments guaranteed for ten (10), fifteen (15) or twenty
            (20) years
       (c)  Joint and Survivor
       (d)  Payments guaranteed for ten (10), fifteen (15) or twenty (20) years
       (e)  Other offered by UNUM.

       To the extent option (d) is elected for a Variable Annuity, the Annuitant
       may request at any time during the payment period that the present value
       of any remaining installments be paid in one lump sum. However, any lump
       sum so elected will be treated as a withdrawal during the Accumulation
       Period subject to the applicable CDSC stated in Section 7.6.

9.6    RETIRED LIFE CERTIFICATE:  Once an annuity option is selected by a
       Participant, or the Beneficiary of a deceased Participant, UNUM will
       issue to the Annuitant an appropriate Certificate evidencing UNUM's
       obligations.

                               ARTICLE X - LOANS

10.1   GENERAL:  During a Participant's Accumulation Period, the Participant, if
       permitted by the applicable Section 403(b) Plan, may apply for a loan
       under this Contract by completing a loan application available from UNUM.
       Loans are secured by the Participant's Account balance in the Guaranteed
       Interest Division.

10.2   RESTRICTIONS ON LOAN AMOUNT:  The amount and terms of a loan are subject
       to the restrictions imposed under Section 72(p) of the Code, as it may be
       amended from time to time.

       Additionally, the initial amount of a Participant's loan may not exceed
       ninety percent (90%) of the Participant's Account balance in the
       Guaranteed Interest Division.

10.3   MINIMUM LOAN AMOUNT:  The initial amount of a loan must be at least one
       thousand dollars ($1,000).

10.4   NUMBER OF LOANS OUTSTANDING:  A Participant may have only one loan
       outstanding at any time and may not establish more than one loan in any
       six (6) month period. However, a Participant may renegotiate an
       outstanding loan balance once during the term of the loan.

10.5   LOAN INTEREST RATE:  The initial interest rate on a loan will be the
       lesser of (a) the rate being credited in the Guaranteed Interest Division
       as of the date of the loan and (b) the Moody's Corporate Bond Yield
       Average, rounded to the nearest five basis points (0.05%) for the first
       month in the calendar quarter which precedes the date of the loan. The
       loan interest rate will remain fixed for the term of the loan, unless the
       initial interest rate on a hypothetical new loan to the Participant would
       be lower than the Participant's actual loan rate by more than fifty basis
       points (0.50%). In such case, the loan interest rate will be reduced to
       such lower rate as of the first day that such lower rate would
       hypothetically be effective.

10.6   EFFECT OF LOAN ON PARTICIPANT'S ACCOUNT:  When a Participant takes a
       loan, UNUM will subdivide his Participant's Account balance in the
       Guaranteed Interest Division by establishing a loan reserve account in an
       amount initially equal to the initial loan amount. Funds held in the loan
       reserve account are held as security for the loan and will accrue
       interest at a rate which is three percent (3.0%) below the loan interest
       rate. To the extent that the loan interest rate is subsequently reduced,
       the rate credited to funds in the loan reserve account will also be
       reduced in order to maintain the three percent (3.0%) differential.

       As the Participant makes repayments to UNUM on the loan, an amount equal
       to the principal component of the repayment, plus the interest accrued in
       the loan reserve account, will be transferred from his loan reserve
       account back to his Participant's Account balance in the Guaranteed
       Interest Division.

                                       25
<PAGE>
 
       In addition, an amount equal to ten percent (10%) of the principal of the
       loan will be held as security to cover the interest and the CDSC, should
       the Participant fail to make the required quarterly payments of principal
       and interest. This amount will earn interest at the interest rate in
       effect in the Guaranteed Interest Division but will not be available for
       withdrawals. As the principal is reduced, the amount held as security
       will also be reduced.

10.7   DEFAULT IN LOAN REPAYMENT:  If a Participant fails to make any quarterly
       principal and interest payment within thirty (30) days of the payment due
       date, his loan will be in default and UNUM will deduct from his loan
       reserve account and from his Participant's Account balance in the
       Guaranteed Interest Division the principal, due and accrued interest, and
       any CDSC thereon, as of the default date. UNUM will also recharacterize
       the principal and due and accrued interest as a withdrawal.

10.8   RESERVATION OF RIGHTS BY UNUM:  UNUM reserves the right to:

       (a)  Delay making a loan for up to six (6) months from the date the loan
            application is received; or

       (b)  With ninety (90) days written notice to You, amend any portion of
            the loan specifications with regard to applications for new loans;
            or

       (c)  With ninety (90) days written notice to You, discontinue making new
            loans under this Contract.

10.9   LOAN SET-UP CHARGE:  UNUM will charge a Participant the amount specified
       in Section 1.7 each time a loan is established. The amount will be
       withdrawn from the Participant's Account balance.

            ARTICLE XI - DISCONTINUANCE AND TERMINATION OF CONTRACT

11.1   CONTRACT DISCONTINUANCE BY CONTRACTHOLDER:  You may discontinue this
       Contract by written notice to UNUM. This contract will be deemed
       discontinued on the later of the date You specify or the date the written
       notice is received by UNUM.

11.2   CONTRACT DISCONTINUANCE BY UNUM:  UNUM may, at its option, discontinue
       this Contract in whole or in part if (a) You fail to meet the Minimum
       Contribution Amount specified in Section 1.1 or (b) a modification in
       this Contract is necessary in order to comply with Federal or State
       requirements, including the Employee Retirement Income Security Act of
       1974, and You refuse to accept a substantially similar contract offered
       by UNUM that incorporates such modification. Discontinuance pursuant to
       this Section shall be effective as of a date specified by UNUM, provided
       You are given at least fifteen (15) days advance written notice in which
       to cure any remediable defaults. Discontinuance by UNUM supersedes any
       date established under Section 11.1.

<PAGE>
 
       Such determination shall be conclusive for the purpose of this Contract.
       UNUM shall be fully protected in relying on the reports and other
       information furnished by You and need not inquire as to the accuracy or
       completeness of such reports and information.

12.5   MISSTATEMENTS:  If UNUM provides a benefit under this Contract based upon
       misstated or omitted information, including but not limited to
       misstatement of age, UNUM will make adjustments to the benefit to reflect
       the correct information. UNUM is relieved and discharged from any
       liability and responsibility with respect to benefits provided in
       reliance upon information You furnish.

12.6   ASSIGNMENT:  You may not assign this Contract without UNUM's prior
       written consent. A Participant or Beneficiary under this Contract may
       not, unless permitted by law, assign or encumber any payment due under
       this Contract.

12.7   MARKET EMERGENCIES:  If transactions are to be made to or from the
       Variable Investment Division, UNUM may not suspend the right of
       redemption or delay payment for more than seven (7) calendar days after
       tender for redemption, except for (1) any period when the New York Stock
       Exchange is closed (other than customary weekend and holiday closings);
       (2) any period when trading in the markets normally utilized is
       restricted, or an emergency exists as determined by the Securities and
       Exchange Commission, so that disposal of investments or determination of
       the Accumulation Unit Value is not reasonably practicable; or (3) for
       such other periods as the Securities and Exchange Commission by order may
       permit for the protection of the Participants.

12.8   DEFERRAL PERIODS:  If a withdrawal is to be made from the Guaranteed
       Interest Division, UNUM may defer the payment for the period permitted by
       the law of the state in which this Contract was delivered but not more
       than six (6) months after a written election is received by UNUM. During
       the period of deferral, interest at the then current interest rate(s)
       will continue to be credited to a Participant's Account in the Guaranteed
       Interest Division.

12.9   DEDUCTIONS FOR PREMIUM TAXES:  UNUM will deduct from Participant Account
       balances any premium tax levied as a result of the existence of
       Participant Accounts by any state or other governmental entity.

12.10  FACILITY OF PAYMENT:  If any person is, in the judgment of UNUM,
       physically or mentally incapable of personally receiving and giving a
       valid receipt for any payment due him under this Contract, UNUM may,
       unless and until claim shall have been made by a duly appointed legal
       guardian or conservator of the person and property of such person, make
       such payment or any part thereof to such other person or institution
       which, in the judgment of UNUM, is then contributing toward or providing
       for the care and maintenance of such person. In no event will any such
       payment exceed the maximum allowed under the applicable law of the state
       in which this Contract is delivered. Such payment shall fully discharge
       UNUM of its obligations to the extent of the payment.

       UNUM will make any payment which has become due to a Participant or an
       Annuitant and has not been paid prior to his death, to the Participant's
       Beneficiary or Beneficiaries, his

                                       30

<PAGE>
 
       executors or administrators. If no Beneficiary or personal representative
       has been named, UNUM may make payment to any one or more of the surviving
       members of the following classes of relatives; spouse, children,
       grandchildren, brothers, sisters, and parents. Such payment shall fully
       discharge UNUM for all liability to the extent of the payment.

12.11  EVIDENCE OF SURVIVAL:  When a benefit payment is contingent upon the
       survival of any person, evidence of such person's survival must be
       furnished to UNUM, either by such person's endorsement of the check drawn
       for such payment, or by other satisfactory means.

12.12  NON-WAIVER:  The failure on UNUM's part to perform or insist upon the
       strict performance of any provision or condition of this Contract shall
       neither constitute a waiver of UNUM's rights to perform or require
       performance of such provision or condition, nor stop UNUM from exercising
       any other rights it may have in such provision, condition, or otherwise
       in this Contract or any Plan.

12.13  RECEIPT OF NOTICE:  Whenever UNUM receives information establishing any
       right or conferring any benefit upon any Participant or Beneficiary, such
       receipt shall be deemed to take place on any Business Day that such
       information is received.

12.14  SEPARABILITY OF PROVISIONS:  If any provision of this Contract is
       determined to be invalid, the remainder of the provisions shall remain in
       full force and effect.

12.15  THE SEPARATE ACCOUNT:  The Separate Account is registered and operated as
       a Unit Investment Trust under the Investment Company Act of 1940. As
       such, the assets of each Sub-Account are invested in a registered
       management investment company (mutual fund).

       The Separate Account will be legally separated from UNUM's other
       accounts. The Separate Account's assets will, at the time during the year
       that adjustments in the reserves are made, have a value of at least equal
       to the reserves and other contract liabilities with respect to the
       Separate Account, and at all other times, will have a value approximately
       equal to, or in excess of, such reserves and liabilities. The portion of
       the assets having a value equal to, or approximately equal to, the
       reserves and contract liabilities will not be chargeable with liabilities
       arising out of any other business which UNUM may conduct.

       UNUM reserves the right, subject to compliance with applicable law,
       including approval by You or the Participants if required by law, (1) to
       create additional Sub-Accounts, (2) to combine or eliminate Sub-Accounts,
       (3) to transfer assets from one Sub-Account to another, (4) to transfer
       assets to the General Account and other separate accounts, (5) to cause
       the deregistration and subsequent re-registration of the Separate Account
       under the Investment Company Act of 1940, (6) to operate the Separate
       Account under a committee and to discharge such committee at any time,
       and (7) to eliminate any voting rights which You or Participants may have
       with respect to the Separate Account, (8) to amend the Contract to meet
       the requirements of the Investment Company Act of 1940 or other federal
       securities laws and regulations, (9) to operate the Separate Account in
       any form permitted by law, (10) to substitute shares of another fund for
       the shares held by a Sub-Account, and (11) to make

                                       31
<PAGE>
 
       any change required by the Internal Revenue Code, the Employee Retirement
       Income Security Act of 1974, or the Securities Act of 1933, to the extent
       not provided in Section 12.2.

12.16  PAYMENT OF BENEFITS:  UNUM shall make payment of benefits under this
       Contract directly to a Participant or Beneficiary at the last known
       address on file with UNUM.

12.17  FREE-LOOK PERIOD:  A Participant will receive an Active Life Certificate
       upon UNUM's receipt of a duly completed participation enrollment form. If
       the Participant chooses not to participate under this Contract, he may
       exercise his Free-look right by sending a written notice to UNUM that he
       does not wish to participate under this Contract within ten (10) days
       after the date the Certificate is received by the Participant. For
       purposes of determining the date on which the Participant has sent
       written notice, the postmark date will be used.

       If a Participant exercises his Free-look right in accordance with the
       foregoing procedure, UNUM will refund in full the Participant's aggregate
       Contributions less aggregate withdrawals, or if greater, with respect to
       Contributions to the Variable Investment Division, the Participant's
       Account balance in the Variable Investment Division on the date the
       canceled Certificate is received by UNUM.

                                  ATTACHMENT I
                                  ------------



The formula for the interest equivalency amount (IEA) is:

                                 /29.5/366/
       IEA = ACCT. BAL x ((1 + I )        - 1)

WHERE:

       IEA          is the Interest Equivalency Amount.

       ACCT. BAL.   is the Participant's Account balance at the later of: the
                    beginning of the contract year and the most recent date on
                    which the credited interest rate changed.

       I            is the interest rate currently being credited to the
                    contract


EXAMPLE: The Account balance at the beginning of the year is one hundred
thousand dollars ($100,000) and the interest rate credited to the contract is
six percent (6.00%). The Interest Equivalency Amount for each month of the
current year is:

                             /29.5/366/
       IEA = $100,000 x (1.06        -1)

           =  $470.76
