  /1/The Management Fee for the JAS Worldwide Growth Portfolio reflects a
  reduced fee schedule effective July 1, 1997. The management fee for this
  Portfolio reflects the new rate applied to the net assets as of December
  31, 1997. Other expenses are based on gross expenses of the shares before
  expense offset arrangements for the fiscal year ended December 31, 1997.
  The information for the Fund is net of fee waivers or reductions from Janus
  Capital Corporation. Other waivers, if applicable, are first applied
  against the management fee and then against other expenses. Without such
  waivers or reductions, the Management Fee, Other Expenses and Total Fund
  Expenses for the JAS Worldwide Growth Portfolio would have been 0.72%,
  0.09% and 0.81%. Janus Capital Corporation may modify or terminate the
  waivers or reductions at any time upon at least 90 days' notice to the
  Fund's Board of Trustees.
 
  /2/BAMCO, Inc. will reduce its fee to the extent required to limit Baron
  Capital Asset Fund's total operating expenses to 1.5% for the first $250
  million of assets in the Fund, 1.35% for the Fund assets over $250 million
  and up to $500 million, and 1.25% for Fund assets over $500 million.
  Without the expense limitations, the Fund estimates that actual expenses
  would be 1.6%.

THE NEW FUNDS. Information about each of the New Funds, including their
investment objectives and investment management, is contained below.
 
    THE NEUBERGER & BERMAN ADVISERS MANAGEMENT TRUST: PARTNERS PORTFOLIO
    (the "N&B AMT Partners Portfolio") seeks capital growth by investing in
    common stocks and other equity securities of medium to large
    capitalization established companies. Neuberger & Berman Management
    Incorporated(R) serves as the Fund's investment adviser. Neuberger &
    Berman, LLC serves as the Fund's investment sub-adviser. Neuberger &
    Berman Management Incorporated(R) or its affiliate may compensate
    Lincoln Life or its affiliate for administrative, distribution, or other
    services. The compensation would be based on assets of the Neuberger &
    Berman Advisers Management Trust attributable to the Contracts and to
    certain other contracts issued or administered by Lincoln Life and its
    affiliates.
 
    THE LINCOLN NATIONAL AGGRESSIVE GROWTH FUND, INC. (the "Aggressive
    Growth Fund") seeks to maximize capital appreciation by investing in a
    diversified portfolio of equity securities of small and medium-sized
    companies which have a dominant position within their respective
    industries, are undervalued or have potential for growth in earnings.
    The Fund invests primarily in companies with market capitalizations of
    between $250 million and $5 billion at the time of purchase. Lincoln
    Investment Management, Inc. serves as the Fund's investment adviser.
    Lynch & Mayer, Inc. serves as the Fund's investment sub-adviser.
 
    THE LINCOLN NATIONAL SOCIAL AWARENESS FUND, INC. (the "Social Awareness
    Fund") seeks long-term capital appreciation by investing primarily in a
    portfolio of common stock and securities convertible into common stock,
    which adhere to certain specific social criteria. Lincoln Investment
    Management, Inc. serves as the Fund's investment adviser. Vantage
    Investment Advisors serves as the Fund's investment sub-adviser.
 
    THE JANUS ASPEN SERIES: WORLDWIDE GROWTH PORTFOLIO (the "JAS Worldwide
    Growth Portfolio") seeks long-term growth of capital in a manner
    consistent with the preservation of capital by investing primarily in
    common stocks of foreign and domestic issuers. The Fund has flexibility
    to invest on a worldwide basis in companies and other organizations of
    any size, regardless of country of organization or place of principal
    business activity. The Fund normally invests in issuers from at least
    five different countries, including the United States, but may at times
    invest in fewer than five countries or even a single country. Janus
    Capital Corporation serves as the Fund's investment adviser. Janus
    Capital Corporation or its affiliate may compensate Lincoln Life or its
    affiliate for administrative, distribution, or other services. The
    compensation would be based on assets of the Janus Aspen Series
    attributable to the Contracts and to certain other contracts issued or
    administered by Lincoln Life and its affiliates.
 
    BARON CAPITAL FUNDS TRUST, INSURANCE SHARES: BARON CAPITAL ASSET FUND
    (the "Baron Capital Asset Fund") seeks capital appreciation through
    investments in securities of small sized companies with market
    capitalizations of approximately $100 million to $1 billion and medium
    sized companies with market capitalizations of $1 billion to $2 billion,
    with undervalued assets or favorable growth prospects. BAMCO, Inc.
    serves as the Fund's investment adviser. BAMCO, Inc. or its affiliate
    may compensate Lincoln Life or its affiliate for administrative,
    distribution, or other services. The compensation would be based on
    assets of the Baron Capital Funds Trust attributable to the Contracts
    and to certain other contracts issued or administered by Lincoln Life
    and its affiliates.
 
Additional information about the New Funds, their investment policies, risks,
fees and expenses and all other aspects of their operations, can be found in
the attached prospectuses for the New Funds, which should be read carefully
before investing. THERE IS NO ASSURANCE THAT ANY NEW FUND WILL ACHIEVE ITS
STATED OBJECTIVES. Additional copies of the New Funds' prospectuses, as well
as their Statements of Additional Information, can be obtained directly from
each of the New Funds without charge by writing to the New Fund at the address
noted on the front of the New Fund prospectus.
 
CHANGES UNDER THE CONTRACTS. On or about September 30, 1998, the Lincoln
National Life Insurance Company ("Lincoln Life") and Lincoln National Variable
Annuity Account L ("Account L") filed an application with the Securities and
Exchange Commission (the "SEC") seeking an order approving the substitution of
shares of the Social Awareness Fund for shares of the Calvert Social Balanced
Portfolio (the "Social Balanced Portfolio") and shares of the Aggressive
Growth Fund for shares of the American Century VP Capital Appreciation (the
"Capital Appreciation").
                                                                                
                                       2
<PAGE>
     
If approved, the effect of the share substitution will be to replace the
Social Balanced Portfolio with the Social Awareness Fund, and the Capital
Appreciation with the Aggressive Growth Fund, as investment options under your
Contract. The Social Awareness Fund and the Aggressive Growth Fund are
described in the current prospectus for these New Funds, enclosed herewith.
 
If approved, Lincoln Life would carry out the proposed substitutions as soon
as all necessary regulatory approvals have been obtained, and once the systems
needed to perform the substitution are in place (anticipated to be on or about
May 1, 1999), by redeeming the Social Balanced Portfolio shares in cash and
purchasing with the proceeds shares of the Social Awareness Fund, and by
redeeming the Capital Appreciation shares in cash and purchasing with the
proceeds shares of the Aggressive Growth Fund. If carried out, the proposed
substitutions would result in the involuntary reinvestment of Participants'
cash value invested in the Social Balanced Portfolio and the Capital
Appreciation.
 
From the date of this supplement until at least 30 days after the proposed
substitutions, neither Lincoln Life nor Account L will exercise any rights
reserved by it under any of the Contracts to impose restrictions or fees on
transfers.
 
If you have any questions about these changes, please contact your financial
consultant or call Lincoln Life at 1-800-341-0441.
 
LINCOLN LIFE AND THE VARIABLE ACCOUNT. We are one of the largest stock life
insurance companies in the United States. We are owned by Lincoln National
Corp. ("LNC") which is also organized under Indiana law. LNC's primary
businesses are insurance and financial services. Lincoln Life is the issuer of
the variable annuity Contracts. The obligations set forth in the Contracts,
other than those of the Contractowner, are our obligations. We also serve as
principal underwriter for the Contracts.
 
On May 21, 1998, The Lincoln National Life Insurance Company announced its
intentions to acquire certain domestic individual life insurance business from
Aetna, Inc. via a 100% indemnity reinsurance transaction. The transaction is
expected to close in the fall of 1998.

                    SUPPLEMENT DATED OCTOBER 1, 1998 TO THE
             STATEMENT OF ADDITIONAL INFORMATION DATED MAY 1, 1998
 
This supplement provides performance information in conjunction with certain
changes to the Variable Investment Divisions available for allocation of
Contributions or cash value under the Group Variable Annuity Contracts noted
above (the "Contracts"), effective on October 1, 1998. Please retain this
supplement with your Contract Statement of Additional Information for your
reference. Unless otherwise stated, capitalized terms have the same
definitions as in the prospectus.
 
As of October 1, 1998, five additional investment options, Janus Aspen Series:
Worldwide Growth Portfolio (the "JAS Worldwide Growth Portfolio"), the
Neuberger & Berman Advisers Management Trust: Partners Portfolio (the "N&B AMT
Partners Portfolio"), the Lincoln National Aggressive Growth Fund, Inc. (the
"Aggressive Growth Fund"), the Lincoln National Social Awareness Fund, Inc.
(the "Social Awareness Fund"), and the Baron Capital Funds Trust: Baron
Capital Asset Fund (the "Baron Capital Asset Fund") (together the "New Funds")
will be available under the Contracts. Each New Fund is available through a
new Sub-Account in the Variable Investment Division: the Global Growth
Account, the Mid Cap Value Account, the Mid Cap Growth I Account, the Social
Awareness Account, and the Small Cap Growth Account (together the "New Sub-
Accounts"). The following performance information should be added to the
performance information included in the Contract Statement of Additional
Information.
 
SUB-ACCOUNT PERFORMANCE
 
Standard total return is not available for the New Sub-Accounts, because they
did not commence operations until the date of this supplement.
 
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 New
Funds and the assumption that the Sub-Accounts were in existence for the same
periods as those indicated for the New 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 New 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.

Item 26.  Persons Controlled by or Under Common Control with The Lincoln
          National Life Insurance Company ("Lincoln Life") or Account L

controlled by Lincoln Life although Lincoln Life will follow voting instructions
of Contractholders with respect to voting on certain important matters requiring
a vote of Contractholders.

Item 27.  Number of Contractholders

As of March 31, 1998, Registrant had 245 Contractholders.

Item 28.  Indemnification

Under the Participation Agreements entered into between Lincoln Life 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"), Lincoln Life and its directors,
officers, employees, agents and control persons have been indemnified by the
Funds 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 Lincoln Life against any liability, loss, damages,
costs or expenses which Lincoln Life 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.

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.

Item 29.  Principal Underwriter

          (a)    Lincoln Financial Advisors Corporation also acts as the
                 principal underwriter for Lincoln Life & Annuity Variable

                              JANUS ASPEN SERIES

                         FUND PARTICIPATION AGREEMENT

     THIS AGREEMENT is made this 15th day of September, 1998, between JANUS
ASPEN SERIES, an open-end management investment company organized as a Delaware
business trust (the "Trust"), and The Lincoln National Life Insurance Company, a
life insurance company organized under the laws of the State of Indiana (the
"Company"), on its own behalf and on behalf of each segregated asset account of
the Company set forth on Schedule A, as may be amended from time to time (the
"Accounts").

                             W I T N E S S E T H:
                             ------------------- 

     WHEREAS, the Trust has registered with the Securities and Exchange
Commission as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act"), and has registered the offer
and sale of its shares under the Securities Act of 1933, as amended (the "1933
Act"); and

     WHEREAS, the Trust desires to act as an investment vehicle for separate
accounts established for variable life insurance policies and variable annuity
contracts to be offered by insurance companies that have entered into
participation agreements with the Trust (the "Participating Insurance
Companies"); and

     WHEREAS, the beneficial interest in the Trust is divided into several
series of shares, each series representing an interest in a particular managed
portfolio of securities and other assets (the "Portfolios"); and

     WHEREAS, the Trust has received an order from the Securities and Exchange
Commission granting Participating Insurance Companies and their separate
accounts exemptions from the provisions of Sections 9(a), 13(a), 15(a) and 15(b)
of the 1940 Act, and Rules 6e-2(b)(15) and 6e-3(T)(b)(15) thereunder, to the
extent necessary to permit shares of the Trust to be sold to and held by
variable annuity and variable life insurance separate accounts of both
affiliated and unaffiliated life insurance companies and certain qualified
pension and retirement plans (the "Exemptive Order"); and
<PAGE>
 
     WHEREAS, the Company has registered or will register (unless registration
is not required under applicable law) certain variable life insurance policies
and/or variable annuity contracts under the 1933 Act (the "Contracts"); and

     WHEREAS, the Company has registered or will register (unless registration
is not required pursuant to Section 3(v)(ii) of the 1940 Act) each Account as a
unit investment trust under the 1940 Act; and

     WHEREAS, the Company desires to utilize shares of one or more Portfolios as
an investment vehicle of the Accounts;

     NOW, THEREFORE, in consideration of their mutual promises, the parties
agree as follows:

                       Article I.  SALE OF TRUST SHARES

     1.1   The Trust shall make shares of its Portfolios available to the
Accounts at the net asset value next computed after receipt of such purchase
order by the Trust (or its agent), as established in accordance with the
provisions of the then current prospectus of the Trust. Shares of a particular
Portfolio of the Trust shall be ordered in such quantities and at such times as
determined by the Company to be necessary to meet the requirements of the
Contracts. The Trustees of the Trust (the "Trustees") may refuse to sell shares
of any Portfolio to any person, or suspend or terminate the offering of shares
of any Portfolio if such action is required by law or by regulatory authorities
having jurisdiction or is, in the sole discretion of the Trustees acting in good
faith and in light of their fiduciary duties under federal and any applicable
state laws, necessary in the best interests of the shareholders of such
Portfolio.

     1.2   The Trust will redeem any full or fractional shares of any Portfolio
when requested by the Company on behalf of an Account at the net asset value
next computed after receipt by the Trust (or its agent) of the request for
redemption, as established in accordance with the provisions of the then current
prospectus of the Trust. The Trust shall make payment for such shares in the
manner established from time to time by the Trust, but in no event shall payment
be delayed for a greater period than is permitted by the 1940 Act.

     1.3   For the purposes of Sections 1.1 and 1.2, the Trust hereby appoints
the Company as its agent for the limited purpose of receiving and accepting
purchase and redemption orders resulting from investment in and payments under
the Contracts. Receipt by the Company shall constitute receipt by the Trust
provided that i) such orders are received by the Company in good order prior to
the time the net asset value of each Portfolio is priced in accordance with its
prospectus and ii) the Trust receives notice of such orders by 10:00 a.m. New
York time on the next following Business Day. The Trust will confirm receipt of
each trade in a manner mutually agreeable to the Trust and the Company.
"Business Day" shall mean any day on which the New York Stock Exchange is open
for trading and on which the Trust calculates its net asset value pursuant to
the rules of the Securities and Exchange Commission.

                                       2
<PAGE>
 
     1.4   Purchase orders that are transmitted to the Trust in accordance with
Section 1.3 shall be paid for no later than 2:00 p.m. New York time on the same
Business Day that the Trust receives notice of the order. The Trust shall use
its best efforts to pay for redemption orders that are transmitted to the
Company in accordance with Section 1.2 no later than 2:30 p.m. New York time on
the same Business Day that the Trust receives notice of the order. Payments
shall be made in federal funds transmitted by wire.

     1.5   Issuance and transfer of the Trust's shares will be by book entry
only. Stock certificates will not be issued to the Company or the Account.
Shares ordered from the Trust will be recorded in the appropriate title for each
Account or the appropriate subaccount of each Account.

     1.6   The Trust shall furnish prompt notice to the Company of any income
dividends or capital gain distributions payable on the Trust's shares. The
Company hereby elects to receive all such income dividends and capital gain
distributions as are payable on a Portfolio's shares in additional shares of
that Portfolio. The Company reserves the right, on its behalf and on behalf of
the Account, to revoke this election and to receive all such dividends in cash.
The Trust shall notify the Company of the number of shares so issued as payment
of such dividends and distributions.

     1.7   The Trust shall make the net asset value per share for each Portfolio
available to the Company on a daily basis as soon as reasonably practical after
the net asset value per share is calculated and shall use its best efforts to
make such net asset value per share available by 6 p.m. New York time.

     1.8   The Trust agrees that its shares will be sold only to Participating
Insurance Companies and their separate accounts and to certain qualified pension
and retirement plans to the extent permitted by the Exemptive Order. No shares
of any Portfolio will be sold directly to the general public. The Company agrees
that Trust shares will be used only for the purposes of funding the Contracts
and Accounts listed in Schedule A, as amended from time to time.

                                       3

     1.9   The Trust agrees that all Participating Insurance Companies shall
have the obligations and responsibilities regarding pass-through voting (unless
exempt therefrom) and conflicts of interest corresponding to those contained in
Section 2.8 and Article IV of this Agreement.

                   Article II.   OBLIGATIONS OF THE PARTIES

     2.1   The Trust shall prepare and be responsible for filing with the
Securities and Exchange Commission and any state regulators requiring such
filing all shareholder reports, notices, proxy materials (or similar materials
such as voting instruction solicitation materials), prospectuses and statements
of additional information of the Trust. The Trust shall bear the costs of
registration and qualification of its shares, preparation and filing of the
documents listed in this Section 2.1 and all taxes to which an issuer is subject
on the issuance and transfer of its shares.

     2.2   At the option of the Company, the Trust shall either (a) provide the
Company (at the Company's expense) with as many copies of the Trust's current
prospectus, annual report, semi-annual report and other shareholder
communications, including any amendments or supplements to any of the foregoing,
as the Company shall reasonably request; or (b) provide the Company with a
camera ready copy of such documents in a form suitable for printing. The Trust
shall be responsible for its pro-rated share of the printing costs. The Trust
shall provide the Company with a copy of its statement of additional information
in a form suitable for duplication by the Company. The Trust (at its expense)
shall provide the Company with copies of any Trust-sponsored proxy materials in
such quantity as the Company shall reasonably require for distribution to
Contract owners.

     2.3   The Company shall bear the costs (unless Janus Capital Corporation or
the Trust, pursuant to the terms of the letter to Company dated September 15,
1998, is required to bear the costs) of printing and distributing the Trust's
prospectus, statement of additional information, shareholder reports and other
shareholder communications to owners of and applicants for policies for which
the Trust is serving or is to serve as an investment vehicle. The Company shall
bear the costs of distributing proxy materials (or similar materials such as
voting solicitation instructions) to Contract owners. The Company assumes sole
responsibility for ensuring that such materials are delivered to Contract owners
in accordance with applicable federal and state securities laws.

     2.4   The Company agrees and acknowledges that the Trust's adviser, Janus
Capital Corporation ("Janus Capital"), is the sole owner of the name and mark
"Janus" and that all use of any designation comprised in whole or part of Janus
(a "Janus Mark") under this Agreement shall inure to the benefit of Janus
Capital. Except as provided in Section 2.5, the Company shall not use any Janus
Mark on its own behalf or on behalf of the Accounts or Contracts in any
registration statement, advertisement, sales literature or other materials
relating to the Accounts or Contracts without the prior written consent of Janus
Capital. Such consent will not be unreasonably withheld and if no written
objection is received within 10 business days of receipt, approval will be
deemed given. Upon termination of this Agreement for any reason, the Company
shall cease all use of any Janus Mark(s) as soon as reasonably practicable.

or its designee, a copy of each Contract prospectus or statement of additional
information in which the Trust or its investment adviser is named within 20 days
of the filing of such document with the Securities and Exchange Commission. The
Company shall furnish, or shall cause to be furnished, to the Trust or its
designee, each piece of sales literature or other promotional material in which
the Trust or its investment adviser is named, at least ten Business Days prior
to its use. No such material shall be used if the Trust or its designee
reasonably objects to such use within fifteen Business Days after receipt of
such material.

or its designee, a copy of each Trust prospectus or statement of additional
information in which the Company is named within 20 days of the filing of such

least ten Business Days prior to its use. No such material shall be used if the
Company or its designee reasonably objects to such use within fifteen Business
Days after receipt of such material.

     2.6   The Company shall not give any information or make any
representations or statements on behalf of the Trust or concerning the Trust or
its investment adviser in connection with the sale of the Contracts other than
information or representations contained in and accurately derived from the
registration statement or prospectus for the Trust shares (as such registration
statement and prospectus may be amended or supplemented from time to time),
reports of the Trust, Trust-sponsored proxy statements, or in sales literature
or other promotional material approved by the Trust or its designee, except as
required by legal process or regulatory authorities or with the written
permission of the Trust or its designee. Such consent will not be unreasonably
withheld and if no written objection is received within 10 business days of
receipt, approval will be deemed given.

     2.7   The Trust shall not give any information or make any representations
or statements on behalf of the Company or concerning the Company, the Accounts
or the Contracts other than information or representations contained in and
accurately derived from the registration statement or prospectus for the
Contracts (as such registration statement and prospectus may be amended or
supplemented from time to time), or in materials approved by the Company for
distribution including sales literature or other promotional materials, except
as required by legal process or regulatory authorities or with the written
permission of the Company.

     2.8   So long as, and to the extent that the Securities and Exchange
Commission interprets the 1940 Act to require pass-through voting privileges for
variable policyowners, the Company will provide pass-through voting privileges
to owners of policies whose cash values are invested, through the Accounts, in
shares of the Trust. The Trust shall require all Participating Insurance
Companies to calculate voting privileges in the same manner and the Company
shall be responsible for assuring that the Accounts calculate voting privileges
in the manner established by the Trust. With respect to each Account, the
Company will vote shares of the Trust held by the Account and for which no
timely voting instructions from policyowners are received as well as shares it
owns that are held by that Account, in the same proportion as those shares for
which voting instructions are received. The Company and its agents will in no
way recommend or oppose or interfere with the solicitation of proxies for Trust
shares held by Contract owners without the prior written consent of the Trust,
which consent may be withheld in the Trust's sole discretion.

     2.9   The Company shall notify the Trust of any applicable state insurance
laws that restrict the Portfolios' investments or otherwise affect the operation
of the Trust and shall notify the Trust of any changes in such laws.

                 Article III.  REPRESENTATIONS AND WARRANTIES

     3.1   The Company represents and warrants that it is an insurance company
duly organized and validly existing under the laws of the State of Indiana and
that it has legally and validly established each Account as a segregated asset
account under such law on the date set forth in Schedule A.

     3.2   The Company represents and warrants that each Account (1) has been
registered or, prior to any issuance or sale of the Contracts, will be
registered as a unit investment trust in accordance with the provisions of the
1940 Act or, alternatively (2) has not been registered in proper reliance upon
the exclusion from registration under Section 3(c)(ii) of the 1940 Act.

                                       6
<PAGE>
 
     3.3   The Company represents and warrants that the Contracts or interests
in the Accounts (1) are or, prior to issuance, will be registered as securities
under the 1933 Act or, alternatively (2) are not registered because they are
properly exempt from registration under the 1933 Act or will be offered
exclusively in transactions that are properly exempt from registration under the
1933 Act. The Company further represents and warrants that the Contracts will be
issued and sold in compliance in all material respects with all applicable
federal and state laws.

     3.4   The Trust represents and warrants that it is duly organized and
validly existing under the laws of the State of Delaware.

     3.5   The Trust represents and warrants that the Trust shares offered and
sold pursuant to this Agreement will be registered under the 1933 Act and the
Trust shall be registered under the 1940 Act prior to any issuance or sale of
such shares. The Trust shall amend its registration statement under the 1933 Act
and the 1940 Act from time to time as required in order to effect the continuous
offering of its shares. The Trust shall register and qualify its shares for sale
in accordance with the laws of the various states only if and to the extent
deemed advisable by the Trust.

     3.6   The Trust represents and warrants that the investments of each
Portfolio will comply with Subchapter M and the diversification requirements set
forth in Section 817(h) of the Internal Revenue Code of 1986, as amended
("Code"), and the rules and regulations thereunder. In the event of a breach of
this Section 3.6 by the Trust, it will a) immediately notify the Company of the
breach and b) take the necessary steps to adequately diversify each Portfolio so
as to achieve compliance within the grace period offered by Regulation 1.817-5.

                       Article IV.  POTENTIAL CONFLICTS

     4.1   The parties acknowledge that the Trust's shares may be made available
for investment to other Participating Insurance Companies. In such event, the
Trustees will monitor the Trust for the existence of any material irreconcilable
conflict between the interests of the contract owners of all Participating
Insurance Companies. An irreconcilable material conflict may arise for a variety
of reasons, including: (a) an action by any state insurance regulatory
authority; (b) a change in applicable federal or state insurance, tax, or
securities laws or regulations, or a public ruling, private letter ruling, no-
action or interpretative letter, or any similar action by insurance, tax, or
securities regulatory authorities; (c) an administrative or judicial decision in
any relevant proceeding; (d) the manner in which the investments of any
Portfolio are being managed; (e) a difference in voting instructions given by
variable annuity contract and variable life insurance contract owners; or (f) a
decision by an insurer to disregard the voting instructions of contract owners.
The Trustees shall promptly inform the Company if they determine that an
irreconcilable material conflict exists and the implications thereof.

                                       7
<PAGE>
 
     4.2   The Company agrees to promptly report any potential or existing
conflicts of which it is aware to the Trustees. The Company will assist the
Trustees in carrying out their responsibilities under the Exemptive Order by
providing the Trustees with all information reasonably necessary for the
Trustees to consider any issues raised including, but not limited to,
information as to a decision by the Company to disregard Contract owner voting
instructions.

     4.3   If it is determined by a majority of the Trustees, or a majority of
its disinterested Trustees, that a material irreconcilable conflict exists that
affects the interests of Contract owners, the Company shall, in cooperation with
other Participating Insurance Companies whose contract owners are also affected,
at its expense and to the extent reasonably practicable (as determined by the
Trustees) take whatever steps are necessary to remedy or eliminate the
irreconcilable material conflict, which steps could include: (a) withdrawing the
assets allocable to some or all of the Accounts from the Trust or any Portfolio
and reinvesting such assets in a different investment medium, including (but not
limited to) another Portfolio of the Trust, or submitting the question of
whether or not such segregation should be implemented to a vote of all affected
Contract owners and, as appropriate, segregating the assets of any appropriate
group (i.e., annuity contract owners, life insurance contract owners, or
variable contract owners of one or more Participating Insurance Companies) that
votes in favor of such segregation, or offering to the affected Contract owners
the option of making such a change; and (b) establishing a new registered
management investment company or managed separate account.

     4.4   If a material irreconcilable conflict arises because of a decision by
the Company to disregard Contract owner voting instructions and that decision
represents a minority position or would preclude a majority vote, the Company
may be required, at the Trust's election, to withdraw the affected Account's
investment in the Trust and terminate this Agreement with respect to such
Account; provided, however that such withdrawal and termination shall be limited
to the extent required by the foregoing material irreconcilable conflict as
determined by a majority of the disinterested Trustees. Any such withdrawal and
termination must take place within six (6) months after the Trust gives written
notice that this provision is being implemented. Until the end of such six (6)
month period, the Trust shall continue to accept and implement orders by the
Company for the purchase and redemption of shares of the Trust.

     4.5   If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to the Company conflicts with
the majority of other state regulators, then the Company will withdraw the
affected Account's investment in the Trust and terminate this Agreement with
respect to such Account within six (6) months after the Trustees inform the
Company in writing that it has determined that such decision has created an
irreconcilable material conflict; provided, however, that such withdrawal and
termination shall be limited to the extent required by the foregoing material
irreconcilable conflict as determined by a majority of the disinterested
Trustees. Until the end of such six (6) month period, the Trust shall continue
to accept and implement orders by the Company for the purchase and redemption of
shares of the Trust.

<PAGE>
 
     4.6   For purposes of Sections 4.3 through 4.6 of this Agreement, a
majority of the disinterested Trustees shall determine whether any proposed
action adequately remedies any irreconcilable material conflict, but in no event
will the Company be required to establish a new funding medium for the Contracts
if an offer to do so has been declined by vote of a majority of Contract owners
materially adversely affected by the irreconcilable material conflict. In the
event that the Trustees determine that any proposed action does not adequately
remedy any irreconcilable material conflict, then the Company will withdraw the
Account's investment in the Trust and terminate this Agreement within six (6)
months after the Trustees inform the Company in writing of the foregoing
determination; provided, however, that such withdrawal and termination shall be
limited to the extent required by any such material irreconcilable conflict as
determined by a majority of the disinterested Trustees.

     4.7   The Company shall at least annually submit to the Trustees such
reports, materials or data as the Trustees may reasonably request so that the
Trustees may fully carry out the duties imposed upon them by the Exemptive
Order, and said reports, materials and data shall be submitted more frequently
if deemed appropriate by the Trustees.

     4.8   If and to the extent that Rule 6e-2 and Rule 6e-3(T) are amended, or
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the 1940
Act or the rules promulgated thereunder with respect to mixed or shared funding
(as defined in the Exemptive Order) on terms and conditions materially different
from those contained in the Exemptive Order, then the Trust and/or the
Participating Insurance Companies, as appropriate, shall take such steps as may
be necessary to comply with Rules 6e-2 and 6e-3(T), as amended, and Rule 6e-3,
as adopted, to the extent such rules are applicable.

               breach of this Agreement by the Company.

          (f)  arise out of (i) a failure by TRUST to substantially provide the
               services and furnish the materials under the terms of this
               Agreement; or (ii) a failure by a Portfolio(s) invested in by the

               Portfolio(s) invested in by the Separate Account to qualify as a
               "regulated investment company" under Subchapter M of the code.

     5.2   Indemnification By the Trust. The Trust agrees to indemnify and hold
harmless the Company and each of its directors, officers, employees and agents

     5.3   Neither the Company nor the Trust shall be liable under the
indemnification provisions of Sections 5.1 or 5.2, as applicable, with respect
to any Losses incurred or assessed against an Indemnified Party that arise from
such Indemnified Party's willful misfeasance, bad faith or negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations or duties under this Agreement.

     5.4   Neither the Company nor the Trust shall be liable under the
indemnification provisions of Sections 5.1 or 5.2, as applicable, with respect
to any claim made against an Indemnified Party unless such Indemnified Party
shall have notified the other party in writing within a reasonable time after
the summons, or other first written notification, giving information of the
nature of the claim shall have been served upon or otherwise received by such
Indemnified Party (or after such Indemnified Party shall have received notice of
service upon or other notification to any designated agent), but failure to
notify the party against whom indemnification is sought of any such claim shall
not relieve that party from any liability which it may have to the Indemnified
Party in the absence of Sections 5.1 and 5.2.

     5.5   In case any such action is brought against the Indemnified Parties,
the indemnifying party shall be entitled to participate, at its own expense, in
the defense of such action. The indemnifying party also shall be entitled to
assume the defense thereof, with counsel reasonably satisfactory to the party
named in the action. After notice from the indemnifying party to the Indemnified
Party of an election to assume such defense, the Indemnified Party shall bear
the fees and expenses of any additional counsel retained by it, and the
indemnifying party will not be liable to the Indemnified Party under this
Agreement for any legal or other expenses subsequently incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

               available to meet the requirements of the Contracts as determined
               by the Company. Prompt notice of the election to terminate for
               such cause shall be furnished by the Company. Termination shall
               be effective ten days after the giving of notice by the Company;
               or

          (c)  at the option of the Fund upon institution of formal proceedings

               commission of any state or any other regulatory body regarding
               the Company's duties under this Agreement or related to the sale
               of the Contracts, the operation of each Account, the
               administration of the Contracts or the purchase of Fund shares,
               or an expected ruling, judgment or outcome which would, in the
               Fund's reasonable judgment, materially impair the Company's
               ability to perform the Company's obligations and duties
               hereunder; or

          (d)  at the option of the Company upon institution of formal
               proceedings against the Fund, the Fund's distributor, the Fund's
               investment manager or any sub-investment manager, by the NASD,
               the SEC, or any state securities or insurance commission or any
               other regulatory body regarding the duties of the Fund or its
               distributor under this Agreement, or an expected or anticipated
               ruling, judgment or outcome which would, in the Company's
               reasonable judgment, materially impair the Fund's or the
               distributor's ability to perform Fund's or distributor's
               obligations and duties hereunder; or

          (e)  at the option of the Company upon institution of formal
               proceedings against the Fund's investment manager or sub-
               investment manager by the NASD, the SEC, or any state securities
               or insurance commission or any other regulatory body which would,
               in the good faith opinion of the Company, result in material harm
               to the Accounts, the Company, or Contractowners; or

          (f)  upon requisite vote of the Contract owners having an interest in
               the affected Portfolios (unless otherwise required by applicable
               law) and written approval of the Company, to substitute the
               shares of another investment company for the corresponding shares
               of the Fund in accordance with the terms of the Contracts; or

          (g)  at the option of the Fund in the event any of the Contracts are
               not registered, issued or sold in accordance with applicable
               Federal and/or state law; or

                                       14

          (h)  at the option of the Company or the Fund upon a determination by
               a majority of the Fund Board, or a majority of disinterested Fund
               Board members, that an irreconcilable material conflict exists
               among the interests of (i) any contract owners or (ii) the
               interests of the Participating Insurance Companies investing in
               the Fund; or

          (i)  at the option of the Company if the Fund ceases to qualify as a
               Regulated Investment Company under Subchapter M of the Code, or
               under any successor or similar provision, or if the Company
               reasonably believes, based on an opinion of its counsel, that the
               Fund may fail to so qualify; or

          (j)  at the option of the Company if the Fund fails to meet the
               diversification requirements specified in Section 817(h) of the
               Code and any regulations thereunder; or

          (k)  at the option of the Fund if the Contracts cease to qualify as
               annuity contracts or life insurance policies, as applicable,
               under the Code, or if the Fund reasonably believes that the
               Contracts may fail to so qualify; or

          (l)  at the option of either the Fund or the Distributor if the Fund
               or the Distributor, respectively, shall determine, in their sole

               subject of material adverse publicity which is likely to have a
               material adverse impact upon the business and operations of

               a material adverse change in their respective businesses or
               financial condition; or (2) the Fund or its distributor, or both
               of them, shall have been the subject of material adverse
               publicity which is likely to have a material adverse impact upon
               the business and operations of the Company; or

          (n)  upon the assignment of this Agreement (including, without
               limitation, any transfer of the Contracts or the Accounts to
               another insurance company pursuant to an assumption reinsurance

     THIS AGREEMENT, made and entered into this 1st day of July, 1998, by and
between Lincoln National Aggressive Growth Fund, Inc. a corporation organized
under the laws of Maryland (the "Fund"), and THE LINCOLN NATIONAL LIFE INSURANCE
CO., an Indiana insurance corporation (the "Company"), on its own behalf and on
behalf of each separate account of the Company named in Schedule 1 to this
Agreement as in effect at the time this Agreement is executed and such other
separate accounts that may be added to Schedule 1 from time to time in
accordance with the provisions of Article XI of this Agreement (each such
account referred to as the "Account"; collectively, the "Accounts").

     WHEREAS, the Fund is engaged in business as an open-end management
investment company and was established for the purpose of serving as the
investment vehicle for separate accounts established for variable life insurance
policies and variable annuity contracts (collectively referred to as "Variable
Insurance Products," the owners of such products being referred to as "Product
owners") to be offered by insurance companies which have entered into
participation agreements with the Fund ("Participating Insurance Companies");
and

     WHEREAS, the Fund filed with the Securities and Exchange Commission (the
"SEC") and the SEC has declared effective a registration statement (referred to
herein as the "Fund Registration Statement" and the prospectus contained
therein, or filed pursuant to Rule 497 under the 1933 Act, referred to herein as
the "Fund Prospectus") on Form N-lA to register itself as an open-end management
investment company (File No. 811-3212) under the Investment Company Act of 1940,
as amended (the "1940 Act"), and the Fund shares (File No. 2-80743) under the
Securities Act of 1933, as amended (the "1933 Act"); and

     WHEREAS, the Company has filed a registration statement with the SEC to
register under the 1933 Act (unless exempt therefrom) certain variable annuity
contracts and/or variable life insurance policies described in Schedule 2 to
this Agreement as in effect at the time this Agreement is executed and such
other variable annuity contracts and variable life insurance policies which may
be added to Schedule 2 from time to time in accordance with Article XI of this
Agreement (such policies and contracts shall be referred to herein collectively
as the "Contracts," each such registration statement for a class or classes of
contracts listed on Schedule 2 being referred to as the "Contracts Registration
Statement" and the prospectus for each such class or classes being referred to
herein as the "Contracts Prospectus," and the owners of the such contracts, as
distinguished from all Product Owners, being referred to as "Contract Owners");
and

     WHEREAS, each Account, a validly existing separate account, duly authorized
by the Company on the date set forth on Schedule 1, sets aside and invests
assets attributable to the Contracts; and




                                       
<PAGE>
 
     WHEREAS, the Company has registered or will have registered each Account
with the SEC as a unit investment trust under the 1940 Act before any Contracts
are issued by that Account; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, the Company intends to purchase shares on behalf of each Account to
fund its Contracts and the Fund is authorized to sell such shares to unit
investment trusts such as the Accounts at net asset value;

     NOW, THEREFORE, in consideration of their mutual promises, the Company and
the Fund agree as follows:


                        Article I.  SALE OF FUND SHARES

     1.1.   The Fund agrees to sell to the Company those shares which the
Company orders on behalf of the Account, executing such orders on a daily basis
in accordance with Section 1.4 of this Agreement.

     1.2.   The Fund agrees to make shares available for purchase by the Company
on behalf of the Account at the then applicable net asset value per share on
Business Days as defined in Section 1.4 of this Agreement, and the Fund shall
use its best efforts to calculate and deliver such net asset value by 7:00 p.m.,
E.S.T., on each such Business Day. Notwithstanding any other provision in this
Agreement to the contrary, the Board of Directors of the Fund (the "Fund Board")
may suspend or terminate the offering of shares, if such action is required by
law or by regulatory authorities having jurisdiction or if, in the sole
discretion of the Fund Board acting in good faith and in light of its fiduciary
duties under Federal and any applicable state laws, suspension or termination is
necessary and in the best interests of the shareholders (it being understood
that "shareholders" for this purpose shall mean Product owners).

     1.3.   The Fund agrees to redeem, at the Company's request, any full or
fractional shares of the Fund held by the Account or the Company, executing such
requests at the net asset value on a daily basis (LL will expect same day
redemption wires unless unusual circumstances evolve which cause the Fund to
have to redeem securities) in accordance with Section 1.4 of this Agreement, the
applicable provisions of the 1940 Act and the then currently effective Fund
Prospectus. Notwithstanding the foregoing, the Fund may delay redemption of Fund
shares to the extent permitted by the 1940 Act, any rules, regulations or orders
thereunder, or the then currently effective Fund Prospectus.



                                        2
<PAGE>
 
     1.4  (a)  For purposes of Sections 1.1, 1.2 and 1.3, the Company shall be
               the agent of the Fund for the limited purpose of receiving
               redemption and purchase requests from the Account (but not from
               the general account of the Company), and receipt on any Business
               Day by the Company as such limited agent of the Fund prior to the
               time prescribed in the current Fund Prospectus (which as of the
               date of execution of this Agreement is 4 p.m., E.S.T.) shall
               constitute receipt by the Fund on that same Business Day,
               provided that the Fund receives notice of such redemption or
               purchase request by 9:00 a.m., E.S.T. on the next following
               Business Day. For purposes of this Agreement, "Business Day"
               shall mean any day on which the New York Stock exchange is open
               for trading.

          (b)  The Company shall pay for the shares on the same day that it
               places an order with the Fund to purchase those Fund shares for
               an Account. Payment for Fund shares will be made by the Account
               or the Company in Federal Funds transmitted to the Fund by wire
               to be received by 11:00 a.m., E.S.T. on the day the Fund is
               properly notified of the purchase order for shares. The Fund will
               confirm receipt of each trade and these confirmations will be
               received by the Company via Fax or Email by 3:00 p.m. E.S.T. If
               Federal Funds are not received on time, such funds will be
               invested, and shares purchased thereby will be issued, as soon as
               practicable.

          (c)  Payment for shares redeemed by the Account or the Company will be
               made in Federal Funds transmitted to the Company by wire on the
               same day the Fund is notified of the redemption order of shares,
               except that the Fund reserves the right to delay payment of
               redemption proceeds, but in no event may such payment be delayed
               longer than the period permitted under Section 22(e) of the 1940
               Act. The Fund shall not bear any responsibility whatsoever for
               the proper disbursement or crediting of redemption proceeds if
               securities must be redeemed; the Company alone shall be
               responsible for such action.

     1.5.   Issuance and transfer of Fund shares will be by book entry only.
Stock certificates will not be issued to the Company or the Account. Purchase
and redemption orders for Fund shares will be recorded in an appropriate ledger
for the Account or the appropriate subaccount of the Account.

     1.6.   The Fund shall furnish notice as soon as reasonably practicable to
the Company of any income dividends or capital gain distributions payable on any
shares. The Company, on its behalf and on behalf of the Account, hereby elects
to receive all such dividends and distributions as are payable on any shares in
the form of additional shares of that Fund. The Company reserves the right, on
its behalf and on behalf of the Account, to revoke this election and to receive
all such dividends in cash. The Fund shall notify the Company of the number of
shares so issued as payment of such dividends and distributions.

     1.7.   The Fund shall use its best efforts to make the net asset value per
share available to the Company by 7:00 p.m., E.S.T. each Business Day, and in
any event, as soon as reasonably practicable after the net asset value per share
is calculated, and shall calculate such net asset value in accordance with the
then currently effective Fund Prospectus. The Fund shall not be liable for any
information provided to the Company pursuant to this Agreement which information
is based on incorrect information supplied by the Company to the Fund.

     1.8. (a)  The Company may withdraw the Account's investment in the Fund
               only: (i) as necessary to facilitate Contract owner requests;
               (ii) upon a determination by a majority of the Fund Board, or a
               majority of disinterested Fund Board members, that an
               irreconcilable material conflict exists among the interests of
               (x) any Product Owners or (y) the interests of the Participating
               Insurance Companies investing in the Fund; (iii) upon requisite
               vote of the Contractowners having an interest in the Fund to
               substitute the shares of another investment company for shares in
               accordance with the terms of the Contracts; (iv) as required by
               state and/or federal laws or regulations or judicial or other
               legal precedent of general application; or (v) at the Company=s
               sole discretion, pursuant to an order of the SEC under Section
               26(b) of the 1940 Act.

          (b)  The parties hereto acknowledge that the arrangement contemplated
               by this Agreement is not exclusive and that the Fund shares may
               be sold to other insurance companies (subject to Section 1.9
               hereof) and the cash value of the Contracts may be invested in
               other investment companies.

          (c)  The Company shall not, without prior notice to the Fund (unless
               otherwise required by applicable law), take any action to operate
               the Accounts as management investment companies under the 1940
               Act.

     1.9.   The Fund agrees that Fund shares will be sold only to Participating
Insurance Companies and their separate accounts. The Fund will not sell Fund
shares to any insurance company or separate account unless an agreement
complying with Article VII of this Agreement is in effect to govern such sales.
No Fund shares will be sold to the general public.

                  Article II.  REPRESENTATIONS AND WARRANTIES

     2.1.   The Company represents and warrants (a) that the Contracts are

respects with all applicable Federal and state laws and (c) that the Company
will require of every person distributing the Contracts that the Contracts be
offered and sold in compliance in all material respects with all applicable

or, prior to the issuance of any Contracts, will register each Account (unless

will maintain such registrations for so long as any Contracts issued under them
are outstanding.

     2.2.   The Fund represents and warrants that Fund shares sold pursuant to
this Agreement shall be registered under the 1933 Act and duly authorized for

     2.3.   The Fund represents and warrants that it currently qualifies as a
Regulated Investment Company under Subchapter M of the Internal Revenue Code of
1986, as amended (the "Code").  The Fund further represents and warrants that it
will make every effort to continue to qualify and to maintain such qualification

it has ceased to so qualify or that it might not so qualify in the future.

     2.4.    The Fund represents and warrants that it will comply with Section
817(h) of the Code, and all regulations issued thereunder.

     2.5.    The Company represents that the Contracts are currently and at the

policies, whichever is appropriate, under applicable provisions of the Code.
The Company shall make every effort to maintain such treatment and shall notify

Contracts have ceased to be so treated or that they might not be so treated in
the future.

     2.6.    The Fund represents that the Fund's investment policies, fees and

with Section 6.6. The Fund, however, makes no representation as to whether any
aspect of its operations (including, but not limited to, fees and expenses and
investment policies) otherwise complies with the insurance laws or regulations
of any state.  The Company alone shall be responsible for informing the Fund of
any investment restrictions imposed by state insurance law and applicable to the
Fund.

     2.7.    The Fund represents and warrants that it has and maintains a
fidelity bond in accordance with Rule 17g-1 under the 1940 Act. The Fund will
immediately notify the Company in the event the fidelity bond coverage should

   Article III.  PROSPECTUSES AND PROXY STATEMENTS; SALES MATERIAL AND OTHER
                                  INFORMATION
                 

     3.1.   The Fund shall provide the Company with as many copies of the
current Fund Prospectus as the Company may reasonably request. If requested by
the Company in lieu thereof, the Fund at its expense shall provide to the
Company a camera-ready copy, and electronic version,  of the current Fund
Prospectus suitable for printing and other assistance as is reasonably necessary
in order for the Company to have a new Contracts Prospectus printed together
with the Fund Prospectus in one document. See Article V for a detailed
explanation of the responsibility for the cost of printing and distributing Fund
prospectuses.

     3.2.   The Fund Prospectus shall state that the Statement of Additional
Information for the Fund is available from the Fund and the Fund shall provide
such Statement free of charge to the Company and to any outstanding or
prospective Contract owner who requests such Statement.


     3.3. (a)  The Fund at its expense shall provide to the Company a camera-
               ready copy of the Fund's shareholder reports and other
               communications to shareholders (except proxy material), in each
               case in a form suitable for printing, as determined by the
               Company. The Fund shall be responsible for the costs of printing
               and distributing these materials to Contract owners.


          (b)  The Fund at its expense shall be responsible for preparing,
               printing and distributing its proxy material. The Company will
               provide the appropriate Contractowner names and addresses to the
               Fund for this purpose.


     3.4.   The Company shall furnish to the Fund, prior to its use, each piece
            of sales literature or other promotional material in which the Fund
            is named. No such material shall be used, except with the prior
            written permission of the Fund. The Fund agrees to respond to any
            request for approval on a prompt and timely basis. Failure of the
            Fund to respond within 10 days of the request by the Company shall
            relieve the Company of the obligation to obtain the prior written
            permission of the Fund.

     3.5.   The Company shall not give any information or make any
            representations or statements on behalf of the Fund or concerning
            the Fund other than the information or representations contained in
            the Fund Registration Statement or Fund Prospectus, as such
            Registration Statement and Prospectus may be amended or supplemented
            from time to time, or in reports or proxy statements for the Fund,
            or in sales literature or other promotional material approved by the
            Fund, except with the prior written permission of the Fund. The Fund
            agrees to respond to any request for permission on a prompt and
            timely basis. If the Fund does not respond within 10 days of a
            request by the Company, then the Company shall be relieved of the
            obligation to obtain the prior written permission of the Fund.

reports of the Account which are in the public domain or approved in writing by
the Company for distribution to Contract owners, or in sales literature or other
promotional material approved in writing by the Company, except with the prior
written permission of the Company. The Company agrees to respond to any request
for permission on a prompt and timely basis. If the Company fails to respond
within 10 days of a request by the Fund, then the Fund is relieved of the
obligation to obtain the prior written permission of the Company.

     3.7.   The Fund will provide to the Company at least one complete copy of
all Fund Registration Statements, Fund Prospectuses, Statements of Additional
Information, annual and semi-annual reports and other reports, proxy statements,

purposes of preparing a report or other filing to be filed with or submitted to
a regulatory agency. If a party requests any such information before it has been
filed, the other party will provide the requested information if then available
and in the version then available at the time of such request.

          (b)  vote Fund shares attributable to Contract owners for which no

                         Article V. FEES AND EXPENSES

     All expenses incident to performance by the Fund under this Agreement
(including expenses expressly assumed by the Fund pursuant to this Agreement)

Prospectuses and SAIs to existing Contractowners. (If for this purpose the
Company decided to print the Fund Prospectuses and SAIs in a booklet or separate
booklets containing disclosure for the Contracts and for underlying funds other
than those of the Fund, then the Fund shall pay only its proportionate share of
the total cost to distribute the booklet to existing Contractowners.

     The Company is responsible for the cost of printing and distributing Fund
prospectuses and SAIs for new sales; and Account Prospectuses and SAIs for
existing Contractowners. The Company shall have the final decision on choice of

register and qualify the Contracts for sale to the extent required by applicable
securities laws of the various states.

     6.3.   The Fund shall amend the Fund Registration Statement under the 1933
Act and the 1940 Act from time to time as required in order to effect for so

     6.4.   The Company shall be responsible for assuring that any prospectus
offering a Contract that is a life insurance contract where it is reasonably
possible that such Contract would be deemed a "modified endowment contract," as
that term is defined in Section 7702A of the Code, will describe the
circumstances under which a Contract could be treated as a modified endowment
contract (or policy).

     6.5.   To the extent that it decides to finance distribution expenses
pursuant to Rule 12b-1, the Fund undertakes to have a Fund Board of Directors, a
majority of whom are not interested persons of the Fund, formulate and approve
any plan under Rule 12b-1 to finance distribution expenses.

     6.6. (a)  When appropriate in order to inform the Fund of any applicable
               state-mandated investment restrictions with which the Fund must
               comply, the Company shall arrange with the Fund to amend Schedule
               3, pursuant to the requirements of Article XI.

          (b)  Should the Fund become aware of any restrictions which may be
               appropriate for inclusion in Schedule 3, the Company shall be
               informed immediately of the substance of those restrictions.

                       Article VII.  POTENTIAL CONFLICTS

     7.1.  The Company agrees to report to the Board of Directors of the Fund
(the "Board") any potential or existing conflicts between the interests of
Product Owners of all separate accounts investing in the Fund, and to assist the
Board in carrying out its responsibilities under Section 6e-3(T) of the 1940
Act, by providing all information reasonably necessary for the Board to consider
any issues raised, including information as to a decision to disregard voting
instructions of variable contract owners.

                                      10
<PAGE>
 
     7.2.   If a majority of the Board, or a majority of disinterested Board
Members, determines that a material irreconcilable conflict exists, the Board
shall give prompt notice to all Participating Insurance Companies.

          (a)  If a majority of the whole Board, after notice to the Company and
               a reasonable opportunity for the Company to appear before it and
               present its case, determines that the Company is responsible for
               said conflict, and if the Company agrees with that determination,
               the Company shall, at its sole cost and expense, take whatever
               steps are necessary to remedy the material irreconcilable
               conflict. These steps could include: (i) withdrawing the assets
               allocable to some or all of the affected Accounts from the Fund
               and reinvesting such assets in a different investment vehicle, or
               submitting the question of whether such segregation should be
               implemented to a vote of all affected Contractowners and, as
               appropriate, segregating the assets of any particular group
               (i.e., variable annuity Contractowners, variable life insurance
               policyowners, or variable Contractowners of one or more
               Participating Insurance Companies) that votes in favor of such
               segregation, or offering to the affected Contractowners the
               option of making such a change; and (ii) establishing a new
               registered mutual fund or management separate account; or (iii)
               taking such other action as is necessary to remedy or eliminate
               the material irreconcilable conflict.

          (b)  If the Company disagrees with the Board's determination, the
               Company shall file a written protest with the Board, reserving
               its right to dispute the determination as between just the
               Company and the Fund and to seek reimbursement from the Fund for
               the reasonable costs and expenses of resolving the conflict .
               After reserving that right the Company, although disagreeing with
               the Board that it (the Company) was responsible for the conflict,
               shall take the necessary steps, under protest, to remedy the
               conflict, substantially in accordance with paragraph (a) just
               above, for the protection of Contractowners.

          (c)  As between the Company and the Fund, if within 45 days after the
               Board's determination the Company elects to press the dispute, it
               shall so notify the Board in writing. The parties shall then
               attempt to resolve the matter amicably through negotiation by
               individuals from each party who are authorized to settle the
               matter. If the matter has not been amicably resolved within 60
               days from the date of the Company's notice of its intent to press
               the dispute, then before either party shall undertake to litigate
               the dispute it shall be submitted to non-binding arbitration
               conducted expeditiously in accordance with the CPR Rules for Non-
               Administered Arbitration of Business Disputes, by a sole
               arbitrator; provided, however, that if one party has requested
               the other party to seek an amicable resolution and the other
               party has failed to participate, the requesting party may
               initiate arbitration before expiration of the 60-day period set
               out just above.

                                      11
<PAGE>
 
                    If within 45 days of the commencement of the process to
               select an arbitrator the parties cannot agree upon the
               arbitrator, then he or she will be selected from the CPR Panels
               of Neutrals. The arbitration shall be governed by the United
               States Arbitration Act, 9 U.S.C. Sec. 1-16. The place of
               arbitration shall be Fort Wayne, Indiana. The Arbitrator is not
               empowered to award damages in excess of compensatory damages.

          (d)  If the Board shall determine that the Fund or another was
               responsible for the conflict, then the Board shall notify the
               Company immediately of that determination. The Fund shall assure
               the Company that it (the Fund) or that other Participating
               Insurance Company as applicable, shall, at its sole cost and
               expense, take whatever steps are necessary to eliminate the
               conflict.

          (e)  Nothing in Sections 7.2(b) or 7.2(c) shall constitute a waiver of
               any right of action which the Company may have against other
               Participating Insurance Companies for reimbursement of all or
               part of the costs and expenses of resolving the conflict.

     7.3.   If a material irreconcilable conflict arises because of the
Company's decision to disregard Contractowner voting instructions and that
decision represents a minority position or would preclude a majority vote, the
Company shall withdraw (without charge or penalty) the Account's investment in
the Fund, if the Fund so elects.

     7.4.   For purposes of this Article, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable conflict.  However, in no event will the
Fund be required to establish a new funding medium for any variable contract,
nor will the Company be required to establish a new funding medium for any
Contract, if in either case an offer to do so has been declined by a vote of a
majority of affected Contractowners.

                        Article VIII.  INDEMNIFICATION

     8.1.   Indemnification by the Company. The Company agrees to indemnify and
hold harmless the Fund and each person who controls or is associated with the
Fund (other than another Participating Insurance Company) within the meaning of
such terms under the federal securities laws and any officer, trustee, director,
employee or agent of the foregoing, against any and all losses, claims, damages
or liabilities, joint or several (including any investigative, legal and other
expenses reasonably incurred in connection with, and any amounts paid with the
prior written consent of the Company in settlement of, any action, suit or
proceeding or any claim asserted), to which they or any of them may become
subject under any statute or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Contracts
               Registration Statement, Contracts Prospectus, sales literature or
               other promotional material for the Contracts or the Contracts
               themselves (or any amendment or supplement to any of the
               foregoing), or arise out of or are based upon the omission or the
               alleged omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading in light of the circumstances in which they were made;
               provided that this obligation to indemnify shall not apply if
               such statement or omission or such alleged statement or alleged
               omission was made in reliance upon and in conformity with
               information furnished in writing to the Company by the Fund (or a
               person authorized in writing to do so on behalf of the Fund) for
               use in the Contracts Registration Statement, Contracts Prospectus
               or in the Contracts or sales literature (or any amendment or
               supplement) or otherwise for use in connection with the sale of
               the Contracts or Fund shares; or

          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact by or on behalf of the
               Company (other than statements or representations contained in
               the Fund Registration Statement, Fund Prospectus or sales
               literature or other promotional material of the Fund not supplied
               by the Company or persons under its control) or wrongful conduct
               of the Company or persons under its control with respect to the
               sale or distribution of the Contracts or Fund shares; or

                                      13
<PAGE>
 
          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Fund Registration Statement,
               Fund Prospectus or sales literature or other promotional material
               of the Fund or any amendment thereof or supplement thereto, or
               the omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in light of the circumstances in which
               they were made, if such statement or omission was made in
               reliance upon and in conformity with information furnished to the
               Fund by or on behalf of the Company; or

          (d)  arise as a result of any failure by the Company to provide the
               services and furnish the materials or to make any payments under
               the terms of this Agreement; or

          (e)  arise out of any material breach by the Company of this
               Agreement, including but not limited to any failure to transmit a
               request for redemption or purchase of Fund shares on a timely
               basis in accordance with the procedures set forth in Article I;
               or

          (f)  arise as a result of the Company's providing the Fund with
               inaccurate information, which causes the Fund to calculate its
               Net Asset Values incorrectly.

This indemnification will be in addition to any liability which the Company may
otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.2.   Indemnification by the Fund. The Fund agrees to indemnify and hold
harmless the Company and each person who controls or is associated with the
Company within the meaning of such terms under the federal securities laws and
any officer, director, employee or agent of the foregoing, against any and all
losses, claims, damages or liabilities, joint or several (including any
investigative, legal and other expenses reasonably incurred in connection with,
and any amounts paid with the prior written consent of the Fund in settlement
of, any action, suit or proceeding or any claim asserted), to which they or any
of them may become subject under any statute or regulation, at common law or
otherwise, insofar as such losses, claims, damages or liabilities:


          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Fund
               Registration Statement, Fund Prospectus (or any amendment or
               supplement thereto) or sales literature or other promotional
               material of the Fund, or arise out of or are based upon the
               omission or the alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in light of the circumstances in which
               they were made; provided that this obligation to indemnify shall
               not apply if such statement or omission or alleged statement or
               alleged omission was made in reliance upon and in conformity with
               information furnished in writing by the Company to the Fund for
               use in the Fund Registration Statement, Fund Prospectus (or any
               amendment or supplement thereto) or sales literature for the Fund
               or otherwise for use in connection with the sale of the Contracts
               or Fund shares; or

                                      14
<PAGE>
 
          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact made by the Fund (other than
               statements or representations contained in the Fund Registration
               Statement, Fund Prospectus or sales literature or other
               promotional material of the Fund not supplied by the Distributor
               or the Fund or persons under their control) or wrongful conduct
               of the Fund or persons under its control with respect to the sale
               or distribution of the Contracts or Fund shares; or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Contract's Registration
               Statement, Contracts Prospectus or sales literature or other
               promotional material for the Contracts (or any amendment or
               supplement thereto), or the omission or alleged omission to state
               therein a material fact required to be stated therein or
               necessary to make the statements therein not misleading in light
               of the circumstances in which they were made, if such statement
               or omission was made in reliance upon information furnished in
               writing by the Fund to the Company (or a person authorized in
               writing to do so on behalf of the Fund); or

          (d)  arise as a result of any failure by the Fund to provide the
               services and furnish the materials under the terms of this
               Agreement (including, but not by way of limitation, a failure,
               whether unintentional or in good faith or otherwise: (i) to
               comply with the diversification requirements specified in
               Sections 2.4 and 6.1 in Article VI of this Agreement; and (ii) to
               provide the Company with accurate information sufficient for it
               to calculate its accumulation and/or annuity unit values in
               timely fashion as required by law and by the Contracts
               Prospectuses); or

          (e)  arise out of any material breach by the Fund of this Agreement.

This indemnification will be in addition to any liability which the Fund may
otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.3.   Indemnification Procedures.  After receipt by a party entitled to
indemnification ("indemnified party") under this Article VIII of notice of the
commencement of any action, if a claim in respect thereof is to be made by the
indemnified party against any person obligated to provide indemnification under
this Article VIII ("indemnifying party"), such indemnified party will notify the
indemnifying party in writing of the commencement thereof as soon as practicable
thereafter, provided that the omission to so notify the indemnifying party will
not relieve it from any liability under this Article VIII, except to the extent
that the omission results in a failure of actual notice to the indemnifying
party and such indemnifying party is damaged solely as a result of the failure
to give such notice.  The indemnifying party, upon the request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding.  In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment.

     A successor by law of the parties to this Agreement shall be entitled to
the benefits of the indemnification contained in this Article VIII.  The
indemnification provisions contained in this Article VIII shall survive any
termination of this Agreement.

                          Article IX. APPLICABLE LAW

     9.1.   This Agreement shall be construed and the provisions hereof
interpreted under and in accordance with the laws of the state of Indiana,
without giving effect to the principles of conflicts of law.

     9.2.   This Agreement shall be subject to the provisions of the 1933,
1934 and 1940 Acts, and the rules and regulations and rulings thereunder,
including such exemptions from those statutes, rules and regulations as the SEC
may grant, and the terms hereof shall be limited, interpreted and construed in
accordance therewith.

     10.1.   This Agreement shall terminate:

          (a)  at the option of any party upon 120 days advance written notice
               to the other parties; or

          (b)  at the option of the Company if shares of the Fund are not
               available to meet the requirements of the Contracts as determined
               by the Company. Prompt notice of the election to terminate for
               such cause shall be furnished by the Company. Termination shall
               be effective ten days after the giving of notice by the Company;
               or

          (c)  at the option of the Fund upon institution of formal proceedings
               against the Company by the NASD, the SEC, the insurance
               commission of any state or any other regulatory body regarding
               the Company's duties under this Agreement or related to the sale
               of the Contracts, the operation of the Account, the
               administration of the Contracts or the purchase of Fund shares;

          (d)  at the option of the Company upon institution of formal
               proceedings against the Fund, the investment advisor or any sub-
               investment advisor, by the NASD, the SEC, or any state securities
               or insurance commission or any other regulatory body; or

                                      17
<PAGE>
 
          (e)  upon requisite vote of the Contract owners having an interest in
               the Fund (unless otherwise required by applicable law) and
               written approval of the Company, to substitute the shares of
               another investment company for the corresponding shares of the
               Fund in accordance with the terms of the Contracts; or

          (f)  at the option of the Fund in the event any of the Contracts are
               not registered, issued or sold in accordance with applicable
               Federal and/or state law; or

          (g)  at the option of the Company or the Fund upon a determination by
               a majority of the Fund Board, or a majority of disinterested Fund
               Board members, that an irreconcilable material conflict exists
               among the interests of (i) any Product owners or (ii) the
               interests of the Participating Insurance Companies investing in
               the Fund; or

          (h)  at the option of the Company if the Fund ceases to qualify as a
               Regulated Investment Company under Subchapter M of the Code, or
               under any successor or similar provision, or if the Company
               reasonably believes, based on an opinion of its counsel, that the
               Fund may fail to so qualify; or

                                      18

          (i)  at the option of the Company if the Fund fails to meet the
               diversification requirements specified in Section 817(h) of the
               Code and any regulations thereunder; or

          (j)  at the option of the Fund if the Contracts cease to qualify as
               annuity contracts or life insurance policies, as applicable,
               under the Code, or if the Fund reasonably believes that the
               Contracts may fail to so qualify; or

          (k)  at the option of the Fund if the Fund shall determine, in its
               sole judgment exercised in good faith, that either (1) the
               Company shall have suffered a material adverse change in its
               business or financial condition; or (2) the Company shall have
               been the subject of material adverse publicity which is likely to
               have a material adverse impact upon the business and operations
               of the Fund; or

          (l)  at the option of the Company, if the Company shall determine, in
               its sole judgment exercised in good faith, that: (1) the Fund
               shall have suffered a material adverse change in its business or
               financial condition; or (2) the Fund shall have been the subject
               of material adverse publicity which is likely to have a material
               adverse impact upon the business and operations of the Company;
               or

          (m)  automatically upon the assignment of this Agreement (including,
               without limitation, any transfer of the Contracts or the Accounts
               to another insurance company pursuant to an assumption
               reinsurance agreement) unless the non-assigning party consents
               thereto or unless this Agreement is assigned to an affiliate of
               the Company or the Fund, as the case may be.

     10.2.   Notice Requirement.  Except as otherwise provided in Section 10.1,
no termination of this Agreement shall be effective unless and until the party
terminating this Agreement gives prior written notice to the other party of its
intent to terminate, which notice shall set forth the basis for such
termination.  Furthermore:

          (a)  In the event that any termination is based upon the provisions of
               Article VII or the provisions of Section 10.1(a) of this
               Agreement, such prior written notice shall be given in advance of
               the effective date of termination as required by such provisions;
               and

          (b)  in the event that any termination is based upon the provisions of
               Section 10.1(c) or 10.1(d) of this Agreement, such prior written
               notice shall be given at least ninety (90) days before the
               effective date of termination, or sooner if required by law or
               regulation.

     10.3.  Effect of Termination

          (a)  Notwithstanding any termination of this Agreement pursuant to
               Section 10.1 of this Agreement, the Fund will, at the option of
               the Company, continue to make available additional Fund shares
               for so long after the termination of this Agreement as the
               Company desires, pursuant to the terms and conditions of this
               Agreement as provided in paragraph (b) below, for all Contracts
               in effect on the effective date of termination of this Agreement
               (hereinafter referred to as "Existing Contracts"). Specifically,
               without limitation, if the Company so elects to make additional
               Fund shares available, the owners of the Existing Contracts or
               the Company, whichever shall have legal authority to do so, shall
               be permitted to reallocate investments in the Fund, redeem
               investments in the Fund and/or invest in the Fund upon the making
               of additional purchase payments under the Existing Contracts.

          (b)  If Fund shares continue to be made available after such
               termination, the provisions of this Agreement shall remain in
               effect except for Section 10.1(a) and thereafter either the Fund
               or the Company may terminate the Agreement, as so continued
               pursuant to this Section 10.3, upon prior written notice to the
               other party, such notice to be for a period that is reasonable
               under the circumstances but, if given by the Fund, need not be
               for more than six months.

          (c)  The parties agree that this Section 10.3 shall not apply to any
               termination made pursuant to Article VII, and the effect of such
               Article VII termination shall be governed by the provisions set
               forth or incorporated by reference therein.

new classes of variable annuity contracts and variable life insurance policies
to be issued by the Company through new or existing Separate Accounts investing
in the Fund.  The provisions of this Agreement shall be equally applicable to
each such separate account and each such class of contracts or policies, unless
the context otherwise requires.  Any such amendment must be signed by the
parties and must bear an effective date for that amendment.

                             Article XII.  NOTICES

Lincoln National Aggressive Growth Fund, Inc. State-mandated Investment
Restrictions Applicable to the Fund As of July 1, 1998

The California Department of Insurance has established the following Guidelines
for an underlying portfolio of a Separate Account:

Borrowing. The borrowing limit for any fund is 33 1/3 percent of total assets.
Entering into a reverse repurchase agreement shall be considered "borrowing" as
that term is used herein.

Foreign investments - diversification

The diversification guidelines to be followed by international and global funds
are as follows:

          a.   An international fund or a global fund is sufficiently
               diversified if it is invested in a minimum of three different
               countries at all times, and has invested no more than 50 percent
               of total assets in any one second-tier country and no more than
               25 percent of total assets in any one third-tier country. First-
               tier countries are: Germany, the United Kingdom, Japan, the
               United States, France, Canada, and Australia. Second-tier
               countries are all countries not in the first or third tier. 
               Third-tier countries are countries identified as "emerging" or
               "developing" by the International Bank for Reconstruction and
               Development ("World Bank") or International Finance Corporation.

          b.   A regional fund is sufficiently diversified if it is invested in
               a minimum of three countries. The name of the fund must
               accurately describe the fund.

          c.   The name of the single country fund must accurately describe the
               fund.

          d.   An index fund must substantially mirror the index.

                (Former Title: "Agreement to Purchase Shares")
                                    Between
                    THE LINCOLN NATIONAL LIFE INSURANCE CO.
                                      And

                  LINCOLN NATIONAL SOCIAL AWARENESS FUND, INC.

     THIS AGREEMENT, made and entered into this 1st day of July, 1998,
by and between Lincoln National Social Awareness Fund, Inc.  a corporation
organized under the laws of Maryland (the "Fund"), and THE LINCOLN NATIONAL LIFE
INSURANCE CO., an Indiana insurance corporation (the "Company"), on  its  own
behalf  and  on behalf of each separate account of the Company named in Schedule
1 to this Agreement as in effect at the time this Agreement is executed and such
other separate accounts that may be added to Schedule 1 from time to time in
accordance with the provisions of Article XI of this Agreement (each such
account referred to as the "Account"; collectively, the "Accounts").

     WHEREAS, the Fund is engaged in business as an open-end management
investment company and was established for the purpose of serving as the
investment vehicle for separate accounts established for variable life insurance
policies and variable annuity contracts (collectively referred to as "Variable
Insurance Products," the owners of such products being referred to as "Product
owners") to be offered by insurance companies which have entered into
participation agreements with the Fund ("Participating Insurance Companies");
and

     WHEREAS, the Fund filed with the Securities and Exchange Commission (the
"SEC") and the SEC has declared effective a registration statement (referred to
herein as the "Fund Registration Statement" and the prospectus contained
therein, or filed pursuant to Rule 497 under the 1933 Act, referred to herein as
the "Fund Prospectus") on Form N-lA to register itself as an open-end management
investment company (File No. 811-3212) under the Investment Company Act of 1940,
as amended (the "1940 Act"), and the Fund shares (File No. 2-80743) under the
Securities Act of 1933, as amended (the "1933 Act"); and

     WHEREAS, the Company has filed a registration statement with the SEC to
register under the 1933 Act (unless exempt therefrom) certain variable annuity
contracts and/or variable life insurance policies described in Schedule 2 to
this Agreement as in effect at the time this Agreement is executed and such
other variable annuity contracts and variable life insurance policies which may
be added to Schedule 2 from time to time in accordance with Article XI of this
Agreement (such policies and contracts shall be referred to herein collectively
as the "Contracts," each such registration statement for a class or classes of
contracts listed on Schedule 2 being referred to as the "Contracts Registration
Statement" and the prospectus for each such class or classes being referred to
herein as the "Contracts Prospectus," and the owners of the such contracts, as
distinguished from all Product Owners, being referred to as "Contract Owners");
and

     WHEREAS, each Account, a validly existing separate account, duly
authorized by the Company on the date set forth on Schedule 1, sets aside and
invests assets attributable to the Contracts; and
<PAGE>
 
     WHEREAS, the Company has registered or will have registered each Account
with the SEC as a unit investment trust under the 1940 Act before any Contracts
are issued by that Account; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, the Company intends to purchase shares on behalf of each Account to
fund its Contracts and the Fund is authorized to sell such shares to unit
investment trusts such as the Accounts at net asset value; and

      WHEREAS, pursuant to Articles of Merger approved by the Company in 1988,
the Company succeeded to all the legal rights and responsibilities of Lincoln
National Pension Insurance Company, the signatory to the original Agreement to
Purchase Shares, which this Agreement amends and restates; and

        NOW, THEREFORE, in consideration of their mutual promises, the Company
and the Fund agree as follows:

                        Article I.  SALE OF FUND SHARES

     1.1.   The Fund agrees to sell to the Company those shares which the
Company orders on behalf of the Account, executing such orders on a daily basis
in accordance with Section 1.4 of this Agreement.

     1.2.   The Fund agrees to make shares  available for purchase by the
Company on behalf of the Account at the then applicable net asset value per
share on Business Days as defined in Section 1.4 of this Agreement, and the Fund
shall use its best efforts to calculate and deliver such net asset value by 7:00
p.m., E.S.T., on each such Business Day.  Notwithstanding any other provision in
this Agreement to the contrary, the Board of Directors of the Fund (the "Fund
Board") may suspend or terminate the offering of  shares, if such action is
required by law or by regulatory authorities having jurisdiction or if, in the
sole discretion of the Fund Board acting in good faith and in light of its
fiduciary duties under Federal and any applicable state laws, suspension or
termination is necessary and in the best interests of the shareholders  (it
being understood that "shareholders" for this purpose shall mean Product
owners).

     1.3.   The Fund agrees to redeem, at the Company's request, any full or
fractional shares of the Fund held by the Account or the Company, executing such
requests at the net asset value on a daily basis (LL will expect same day
redemption wires unless unusual circumstances evolve which cause the Fund to
have to redeem securities) in accordance with Section 1.4 of this Agreement, the
applicable provisions of the 1940 Act and the then currently effective Fund
Prospectus.  Notwithstanding the foregoing, the Fund may delay redemption of
Fund shares to the extent permitted by the 1940 Act, any rules, regulations or
orders thereunder, or the then currently effective Fund Prospectus.

     1.4  (a)  For purposes of Sections 1.1, 1.2 and 1.3, the Company shall be
               the agent of the Fund for the limited purpose of receiving
               redemption and purchase requests from the Account (but not from
               the general account of the Company), and receipt on any Business
               Day by the Company as such limited agent of the Fund prior to the
               time prescribed in the current Fund Prospectus (which as of the
               date of execution of this Agreement is 4 p.m., E.S.T.) shall
               constitute receipt by the Fund on that same Business Day,
               provided that the Fund receives notice of such redemption or
               purchase request by 9:00 a.m., E.S.T. on the next following
               Business Day. For purposes of this Agreement, "Business Day"
               shall mean any day on which the New York Stock exchange is open
               for trading.

          (b)  The Company shall pay for the shares on the same day that it
               places an order with the Fund to purchase those Fund shares for
               an Account. Payment for Fund shares will be made by the Account
               or the Company in Federal Funds transmitted to the Fund by wire
               to be received by 11:00 a.m., E.S.T. on the day the Fund is
               properly notified of the purchase order for shares. The Fund will
               confirm receipt of each trade and these confirmations will be
               received by the Company via Fax or Email by 3:00 p.m. E.S.T. If
               Federal Funds are not received on time, such funds will be
               invested, and shares purchased thereby will be issued, as soon as
               practicable.

          (c)  Payment for shares redeemed by the Account or the Company will be
               made in Federal Funds transmitted to the Company by wire on the
               same day the Fund is notified of the redemption order of shares,
               except that the Fund reserves the right to delay payment of
               redemption proceeds, but in no event may such payment be delayed
               longer than the period permitted under Section 22(e) of the 1940
               Act. The Fund shall not bear any responsibility whatsoever for
               the proper disbursement or crediting of redemption proceeds if
               securities must be redeemed; the Company alone shall be
               responsible for such action.

     1.5.  Issuance and transfer of Fund shares will be by book entry only.
Stock certificates will not be issued to the Company or the Account.  Purchase
and redemption orders for Fund shares will be recorded in an appropriate ledger
for the Account or the appropriate subaccount of the Account.

     1.6.   The Fund shall furnish notice as soon as reasonably practicable to
the Company of any income dividends or capital gain distributions payable on any
shares.  The Company, on its behalf and on behalf of the Account, hereby elects
to receive all such dividends and distributions as are payable on any shares in
the form of additional shares of that Fund.  The Company reserves the right, on
its behalf and on behalf of the Account, to revoke this election and to receive
all such dividends in cash.  The Fund shall notify the Company of the number of
shares so issued as payment of such dividends and distributions.

                                       3

     1.7.   The Fund shall use its best efforts to make the net asset value
per share available to the Company by 7:00 p.m., E.S.T. each Business Day, and
in any event, as soon as reasonably practicable after the net asset value per
share is calculated, and shall calculate such net asset value in accordance with
the then currently effective Fund Prospectus.  The Fund shall not be liable for
any information provided to the Company pursuant to this Agreement which
information is based on incorrect information supplied by the Company to the
Fund.

     1.8. (a)  The Company may withdraw the Account's investment in the Fund
               only: (i) as necessary to facilitate Contract owner requests;
               (ii) upon a determination by a majority of the Fund Board, or a
               majority of disinterested Fund Board members, that an
               irreconcilable material conflict exists among the interests of
               (x) any Product Owners or (y) the interests of the Participating
               Insurance Companies investing in the Fund; (iii) upon requisite
               vote of the Contractowners having an interest in the Fund to
               substitute the shares of another investment company for shares in
               accordance with the terms of the Contracts; (iv) as required by
               state and/or federal laws or regulations or judicial or other
               legal precedent of general application; or (v) at the Company=s
               sole discretion, pursuant to an order of the SEC under Section
               26(b) of the 1940 Act.

          (b)  The parties hereto acknowledge that the arrangement contemplated
               by this Agreement is not exclusive and that the Fund shares may
               be sold to other insurance companies (subject to Section 1.9
               hereof) and the cash value of the Contracts may be invested in
               other investment companies.

          (c)  The Company shall not, without prior notice to the Fund (unless
               otherwise required by applicable law), take any action to operate
               the Accounts as management investment companies under the 1940
               Act.

     1.9.   The Fund agrees that Fund shares will be sold only to Participating
Insurance Companies and their separate accounts.  The Fund will not sell Fund
shares to any insurance company or separate account unless an agreement
complying with Article VII of this Agreement is in effect to govern such sales.
No Fund shares will be sold to the general public.

                  Article II.  REPRESENTATIONS AND WARRANTIES

     2.1.   The Company represents and warrants (a) that the Contracts are

current Fund Prospectus as the Company may reasonably request. If requested by
the Company in lieu thereof, the Fund at its expense shall provide to the

representations or statements on behalf of the Fund or concerning the Fund other
than the information or representations contained in the Fund Registration

               in timely fashion; and
               
          (c)  vote Fund shares held by the Company on its own behalf or on
               behalf of the Account that are not attributable to Contract
               owners in the same proportion as Fund shares of such Series for

shall be paid by the Fund to the extent permitted by law.  Except as may
otherwise be provided in Section 1.4 and Article VII of this Agreement, the

under Rule 12b-1 under the 1940 Act.

     The Fund is responsible for the cost of printing and distributing Fund
Prospectuses and SAIs to existing Contractowners. (If for this purpose the
Company decided to print the Fund Prospectuses and SAIs in a booklet or separate
booklets containing disclosure for the Contracts and for underlying funds other
than those of the Fund, then the Fund shall pay only its proportionate share of
the total cost to distribute the booklet to existing Contractowners.)

     The Company is responsible for the cost of printing and distributing Fund
prospectuses and SAIs for new sales; and Account Prospectuses and SAIs for
existing Contractowners. The Company shall have the final decision on choice of
printer for all Prospectuses and SAIs.

                     Article VI.  COMPLIANCE UNDERTAKINGS

     6.2.   The Company shall amend the Contracts Registration Statements
under the 1933 Act and the Account's Registration Statement under the 1940 Act
from time to time as required in order to effect the continuous offering of the
Contracts or as may otherwise be required by applicable law.  The Company shall
register and qualify the Contracts for sale to the extent required by applicable
securities laws of the various states.

     6.3.   The Fund shall amend the Fund Registration Statement under the
1933 Act and the 1940 Act from time to time as required in order to effect for
so long as Fund shares are sold the continuous offering of Fund shares as
described in the then currently effective Fund Prospectus.  The Fund shall
register and qualify Fund shares for sale to the extent required by applicable
securities laws of the various states.

     6.4.   The Company shall be responsible for assuring that any prospectus
offering a Contract that is a life insurance contract where it is reasonably
possible that such Contract would be deemed a "modified endowment contract," as
that term is defined in Section 7702A of the Code, will describe the
circumstances under which a Contract could be treated as a modified endowment
contract (or policy).

     6.5.   To the extent that it decides to finance distribution expenses
pursuant to Rule 12b-1, the Fund undertakes to have a Fund Board of Directors, a
majority of whom are not interested persons of the Fund, formulate and approve
any plan under Rule 12b-1 to finance distribution expenses.

     6.6. (a)  When appropriate in order to inform the Fund of any applicable
               state-mandated investment restrictions with which the Fund must
               comply, the Company shall arrange with the Fund to amend Schedule
               3, pursuant to the requirements of Article XI.

          (b)  Should the Fund become aware of any restrictions which may be
               appropriate for inclusion in Schedule 3, the Company shall be
               informed immediately of the substance of those restrictions.

                       Article VII.  POTENTIAL CONFLICTS

     7.1.   The Company agrees to report to the Board of Directors of the Fund
(the "Board") any potential or existing conflicts between the interests of
Product Owners of all separate accounts investing in the Fund, and to assist the
Board in carrying out its responsibilities under Section 6e-3(T) of the 1940
Act, by providing all information reasonably necessary for the Board to consider
any issues raised, including information as to a decision to disregard voting
instructions of variable contract owners.

     7.2.   If a majority of the Board, or a majority of disinterested Board
Members, determines that a material irreconcilable conflict exists, the Board
shall give prompt notice to all Participating Insurance Companies.

          (a)  If a majority of the whole Board, after notice to the Company and
               a reasonable opportunity for the Company to appear before it and
               present its case, determines that the Company is responsible for
               said conflict, and if the Company agrees with that determination,
               the Company shall, at its sole cost and expense, take whatever
               steps are necessary to remedy the material irreconcilable
               conflict. These steps could include: (i) withdrawing the assets
               allocable to some or all of the affected Accounts from the Fund
               and reinvesting such assets in a different investment vehicle, or
               submitting the question of whether such segregation should be
               implemented to a vote of all affected Contractowners and, as
               appropriate, segregating the assets of any particular group
               (i.e., variable annuity Contractowners, variable life insurance
               policyowners, or variable Contractowners of one or more
               Participating Insurance Companies) that votes in favor of such
               segregation, or offering to the affected Contractowners the
               option of making such a change; and (ii) establishing a new
               registered mutual fund or management separate account; or (iii)
               taking such other action as is necessary to remedy or eliminate
               the material irreconcilable conflict.

                                       11
<PAGE>
 
          (b)  If the Company disagrees with the Board's determination, the
               Company shall file a written protest with the Board, reserving
               its right to dispute the determination as between just the
               Company and the Fund and to seek reimbursement from the Fund for
               the reasonable costs and expenses of resolving the conflict.
               After reserving that right the Company, although disagreeing with
               the Board that it (the Company) was responsible for the conflict,
               shall take the necessary steps, under protest, to remedy the
               conflict, substantially in accordance with paragraph (a) just
               above, for the protection of Contractowners.

          (c)  As between the Company and the Fund, if within 45 days after the
               Board's determination the Company elects to press the dispute, it
               shall so notify the Board in writing. The parties shall then
               attempt to resolve the matter amicably through negotiation by
               individuals from each party who are authorized to settle the
               matter. If the matter has not been amicably resolved within 60
               days from the date of the Company=s notice of its intent to press
               the dispute, then before either party shall undertake to litigate
               the dispute it shall be submitted to non-binding arbitration
               conducted expeditiously in accordance with the CPR Rules for Non-
               Administered Arbitration of Business Disputes, by a sole
               arbitrator; provided, however, that if one party has requested
               the other party to seek an amicable resolution and the other
               party has failed to participate, the requesting party may
               initiate arbitration before expiration of the 60-day period set
               out just above.

               If within 45 days of the commencement of the process to select an
               arbitrator the parties cannot agree upon the arbitrator, then he
               or she will be selected from the CPR Panels of Neutrals. The
               arbitration shall be governed by the United States Arbitration
               Act, 9 U.S.C. Sec. 1-16. The place of arbitration shall be Fort
               Wayne, Indiana. The Arbitrator is not empowered to award damages
               in excess of compensatory damages.

          (d)  If the Board shall determine that the Fund or another was
               responsible for the conflict, then the Board shall notify the
               Company immediately of that determination. The Fund shall assure
               the Company that it (the Fund) or that other Participating
               Insurance Company as applicable, shall, at its sole cost and
               expense, take whatever steps are necessary to eliminate the
               conflict.

          (e)  Nothing in Sections 7.2(b) or 7.2(c) shall constitute a waiver of
               any right of action which the Company may have against other
               Participating Insurance Companies for reimbursement of all or
               part of the costs and expenses of resolving the conflict.

     7.3.   If a material irreconcilable conflict arises because of the
Company's decision to disregard Contractowner voting instructions and that
decision represents a minority position or would preclude a majority vote, the
Company shall withdraw (without charge or penalty) the Account's investment in
the Fund, if the Fund so elects.

     7.4.   For purposes of this Article, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable conflict.  However, in no event will the
Fund be required to establish a new funding medium for any variable contract,
nor will the Company be required to establish a new funding medium for any
Contract, if in either case an offer to do so has been declined by a vote of a
majority of affected Contractowners.

                        Article VIII.  INDEMNIFICATION

     8.1.   Indemnification by the Company.  The Company agrees to indemnify
and hold harmless the Fund and each person who controls or is associated with
the Fund (other than another Participating Insurance Company) within the meaning
of such terms under the federal securities laws and any officer, trustee,
director, employee or agent of the foregoing, against any and all losses,
claims, damages or liabilities, joint or several (including any investigative,
legal and other expenses reasonably incurred in connection with, and any amounts
paid with the prior written consent of the Company in settlement of, any action,
suit or proceeding or any claim asserted), to which they or any of them may
become subject under any statute or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Contracts
               Registration Statement, Contracts Prospectus, sales literature or
               other promotional material for the Contracts or the Contracts
               themselves (or any amendment or supplement to any of the
               foregoing), or arise out of or are based upon the omission or the
               alleged omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading in light of the circumstances in which they were made;
               provided that this obligation to indemnify shall not apply if
               such statement or omission or such alleged statement or alleged
               omission was made in reliance upon and in conformity with
               information furnished in writing to the Company by the Fund (or a
               person authorized in writing to do so on behalf of the Fund) for
               use in the Contracts Registration Statement, Contracts Prospectus
               or in the Contracts or sales literature (or any amendment or
               supplement) or otherwise for use in connection with the sale of
               the Contracts or Fund shares; or

                                       13
<PAGE>
 
          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact by or on behalf of the
               Company (other than statements or representations contained in
               the Fund Registration Statement, Fund Prospectus or sales
               literature or other promotional material of the Fund not supplied
               by the Company or persons under its control) or wrongful conduct
               of the Company or persons under its control with respect to the
               sale or distribution of the Contracts or Fund shares; or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Fund Registration Statement,
               Fund Prospectus or sales literature or other promotional material
               of the Fund or any amendment thereof or supplement thereto, or
               the omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in light of the circumstances in which
               they were made, if such statement or omission was made in
               reliance upon and in conformity with information furnished to the
               Fund by or on behalf of the Company; or

          (d)  arise as a result of any failure by the Company to provide the
               services and furnish the materials or to make any payments under
               the terms of this Agreement; or
               
          (e)  arise out of any material breach by the Company of this
               Agreement, including but not limited to any failure to transmit a
               request for redemption or purchase of Fund shares on a timely
               basis in accordance with the procedures set forth in Article I;
               or

          (f)  arise as a result of the Company=s providing the Fund with
               inaccurate information, which causes the Fund to calculate its
               Net Asset Values incorrectly.

This indemnification will be in addition to any liability which the Company may
otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.2.   Indemnification by the Fund.  The Fund agrees to indemnify and
hold harmless the Company and each person who controls or is associated with the
Company within the meaning of such terms under the federal securities laws and
any officer, director, employee or agent of the foregoing, against any and all
losses, claims, damages or liabilities, joint or several (including any
investigative, legal and other expenses reasonably incurred in connection with,
and any amounts paid with the prior written consent of the Fund in settlement
of, any action, suit or proceeding or any claim asserted), to which they or any
of them may become subject under any statute or regulation, at common law or
otherwise, insofar as such losses, claims, damages or liabilities:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Fund
               Registration Statement, Fund Prospectus (or any amendment or
               supplement thereto) or sales literature or other promotional
               material of the Fund, or arise out of or are based upon the
               omission or the alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in light of the circumstances in which
               they were made; provided that this obligation to indemnify shall
               not apply if such statement or omission or alleged statement or
               alleged omission was made in reliance upon and in conformity with
               information furnished in writing by the Company to the Fund for
               use in the Fund Registration Statement, Fund Prospectus (or any
               amendment or supplement thereto) or sales literature for the Fund
               or otherwise for use in connection with the sale of the Contracts
               or Fund shares; or

          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact made by the Fund (other than
               statements or representations contained in the Fund Registration
               Statement, Fund Prospectus or sales literature or other
               promotional material of the Fund not supplied by the Distributor
               or the Fund or persons under their control) or wrongful conduct
               of the Fund or persons under its control with respect to the sale
               or distribution of the Contracts or Fund shares; or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Contract's Registration
               Statement, Contracts Prospectus or sales literature or other
               promotional material for the Contracts (or any amendment or
               supplement thereto), or the omission or alleged omission to state
               therein a material fact required to be stated therein or
               necessary to make the statements therein not misleading in light
               of the circumstances in which they were made, if such statement
               or omission was made in reliance upon information furnished in
               writing by the Fund to the Company (or a person authorized in
               writing to do so on behalf of the Fund); or

                                       15
<PAGE>
 
          (d)  arise as a result of any failure by the Fund to provide the
               services and furnish the materials under the terms of this
               Agreement (including, but not by way of limitation, a failure,
               whether unintentional or in good faith or otherwise: (i) to
               comply with the diversification requirements specified in
               Sections 2.4 and 6.1 in Article VI of this Agreement; and (ii) to
               provide the Company with accurate information sufficient for it
               to calculate its accumulation and/or annuity unit values in
               timely fashion as required by law and by the Contracts
               Prospectuses); or

          (e)  arise out of any material breach by the Fund of this Agreement.

This indemnification will be in addition to any liability which the Fund may
otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.3.   Indemnification Procedures.  After receipt by a party entitled to
indemnification ("indemnified party") under this Article VIII of notice of the
commencement of any action, if a claim in respect thereof is to be made by the
indemnified party against any person obligated to provide indemnification under
this Article VIII ("indemnifying party"), such indemnified party will notify the
indemnifying party in writing of the commencement thereof as soon as practicable
thereafter, provided that the omission to so notify the indemnifying party will
not relieve it from any liability under this Article VIII, except to the extent
that the omission results in a failure of actual notice to the indemnifying
party and such indemnifying party is damaged solely as a result of the failure
to give such notice.  The indemnifying party, upon the request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding.  In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment.

     A successor by law of the parties to this Agreement shall be entitled to
the benefits of the indemnification contained in this Article VIII.  The
indemnification provisions contained in this Article VIII shall survive any
termination of this Agreement.

                          Article IX. APPLICABLE LAW

     9.1.   This Agreement shall be construed and the provisions hereof
interpreted under and in accordance with the laws of the state of Indiana,
without giving effect to the principles of conflicts of law.

     9.2.   This Agreement shall be subject to the provisions of the 1933,
1934 and 1940 Acts, and the rules and regulations and rulings thereunder,
including such exemptions from those statutes, rules and regulations as the SEC
may grant, and the terms hereof shall be limited, interpreted and construed in
accordance therewith.

                            Article X. TERMINATION

     10.1.   This Agreement shall terminate:

          (a)  at the option of any party upon 120 days advance written notice
               to the other parties; or

          (b)  at the option of the Company if shares of the Fund are not
               available to meet the requirements of the Contracts as determined
               by the Company. Prompt notice of the election to terminate for
               such cause shall be furnished by the Company. Termination shall
               be effective ten days after the giving of notice by the Company;
               or

          (c)  at the option of the Fund upon institution of formal proceedings
               against the Company by the NASD, the SEC, the insurance
               commission of any state or any other regulatory body regarding
               the Company's duties under this Agreement or related to the sale
               of the Contracts, the operation of the Account, the
               administration of the Contracts or the purchase of Fund shares;

                                       17
<PAGE>
 
          (d)  at the option of the Company upon institution of formal
               proceedings against the Fund, the investment advisor or any sub-
               investment advisor, by the NASD, the SEC, or any state securities
               or insurance commission or any other regulatory body; or

          (e)  upon requisite vote of the Contract owners having an interest in
               the Fund (unless otherwise required by applicable law) and
               written approval of the Company, to substitute the shares of
               another investment company for the corresponding shares of the
               Fund in accordance with the terms of the Contracts; or

          (f)  at the option of the Fund in the event any of the Contracts are
               not registered, issued or sold in accordance with applicable
               Federal and/or state law; or

          (g)  at the option of the Company or the Fund upon a determination by
               a majority of the Fund Board, or a majority of disinterested Fund
               Board members, that an irreconcilable material conflict exists
               among the interests of (i) any Product owners or (ii) the
               interests of the Participating Insurance Companies investing in
               the Fund; or

          (h)  at the option of the Company if the Fund ceases to qualify as a
               Regulated Investment Company under Subchapter M of the Code, or
               under any successor or similar provision, or if the Company
               reasonably believes, based on an opinion of its counsel, that the
               Fund may fail to so qualify; or

                                       18
<PAGE>
 
          (i)  at the option of the Company if the Fund fails to meet the
               diversification requirements specified in Section 817(h) of the
               Code and any regulations thereunder; or

          (j)  at the option of the Fund if the Contracts cease to qualify as
               annuity contracts or life insurance policies, as applicable,
               under the Code, or if the Fund reasonably believes that the
               Contracts may fail to so qualify; or

          (k)  at the option of the Fund if the Fund shall determine, in its
               sole judgment exercised in good faith, that either (1) the
               Company shall have suffered a material adverse change in its
               business or financial condition; or (2) the Company shall have
               been the subject of material adverse publicity which is likely to
               have a material adverse impact upon the business and operations
               of the Fund; or
               
          (l)  at the option of the Company, if the Company shall determine, in
               its sole judgment exercised in good faith, that: (1) the Fund
               shall have suffered a material adverse change in its business or
               financial condition; or (2) the Fund shall have been the subject
               of material adverse publicity which is likely to have a material
               adverse impact upon the business and operations of the Company;
               or

          (m)  automatically upon the assignment of this Agreement (including,
               without limitation, any transfer of the Contracts or the Accounts
               to another insurance company pursuant to an assumption
               reinsurance agreement) unless the non-assigning party consents
               thereto or unless this Agreement is assigned to an affiliate of
               the Company or the Fund, as the case may be.

     10.2.   Notice Requirement.  Except as otherwise provided in Section 10.1,
no termination of this Agreement shall be effective unless and until the party
terminating this Agreement gives prior written notice to the other party of its
intent to terminate, which notice shall set forth the basis for such
termination.  Furthermore:

          (a)  In the event that any termination is based upon the provisions of
               Article VII or the provisions of Section 10.1(a) of this
               Agreement, such prior written notice shall be given in advance of
               the effective date of termination as required by such provisions;
               and

          (b)  in the event that any termination is based upon the provisions of
               Section 10.1(c) or 10.1(d) of this Agreement, such prior written
               notice shall be given at least ninety (90) days before the
               effective date of termination, or sooner if required by law or
               regulation.

     10.3.   Effect of Termination

          (a)  Notwithstanding any termination of this Agreement pursuant to
               Section 10.1 of this Agreement, the Fund will, at the option of
               the Company, continue to make available additional Fund shares
               for so long after the termination of this Agreement as the
               Company desires, pursuant to the terms and conditions of this
               Agreement as provided in paragraph (b) below, for all Contracts
               in effect on the effective date of termination of this Agreement
               (hereinafter referred to as "Existing Contracts"). Specifically,
               without limitation, if the Company so elects to make additional
               Fund shares available, the owners of the Existing Contracts or
               the Company, whichever shall have legal authority to do so, shall
               be permitted to reallocate investments in the Fund, redeem
               investments in the Fund and/or invest in the Fund upon the making
               of additional purchase payments under the Existing Contracts.

                                       20
<PAGE>
 
          (b)  If Fund shares continue to be made available after such
               termination, the provisions of this Agreement shall remain in
               effect except for Section 10.1(a) and thereafter either the Fund
               or the Company may terminate the Agreement, as so continued
               pursuant to this Section 10.3, upon prior written notice to the
               other party, such notice to be for a period that is reasonable
               under the circumstances but, if given by the Fund, need not be
               for more than six months.

          (c)  The parties agree that this Section 10.3 shall not apply to any
               termination made pursuant to Article VII, and the effect of such
               Article VII termination shall be governed by the provisions set
               forth or incorporated by reference therein.

          Article XI.  APPLICABILITY TO NEW ACCOUNTS AND NEW CONTRACTS

     The parties to this Agreement may amend the schedules to this Agreement
from time to time to reflect changes in or relating to the Contracts and to add
new classes of variable annuity contracts and variable life insurance policies
to be issued by the Company through new or existing Separate Accounts investing
in the Fund.  The provisions of this Agreement shall be equally applicable to
each such separate account and each such class of contracts or policies, unless
the context otherwise requires.  Any such amendment must be signed by the
parties and must bear an effective date for that amendment.

                             Article XII.  NOTICES

     Any notice shall be sufficiently given when sent by registered or
certified mail to the other party(ies) at the address of such party(ies) set

Lincoln National Social Awareness Fund, Inc. State-mandated Investment
Restrictions Applicable to the Fund As of July 1, 1998

The California Department of Insurance has established the following Guidelines
for an underlying portfolio of a Separate Account:

Borrowing. The borrowing limit for any fund is 33 1/3 percent of total assets.
Entering into a reverse repurchase agreement shall be considered "borrowing" as
that term is used herein.

Foreign investments - diversification

The diversification guidelines to be followed by international and global funds
are as follows:

          a.   An international fund or a global fund is sufficiently
               diversified if it is invested in a minimum of three different
               countries at all times, and has invested no more than 50 percent
               of total assets in any one second-tier country and no more than
               25 percent of total assets in any one third-tier country. First-
               tier countries are: Germany, the United Kingdom, Japan, the
               United States, France, Canada, and Australia. Second-tier
               countries are all countries not in the first or third tier. 
               Third-tier countries are countries identified as "emerging" or
               "developing" by the International Bank for Reconstruction and
               Development ("World Bank") or International Finance Corporation.

          b.   A regional fund is sufficiently diversified if it is invested in
               a minimum of three countries. The name of the fund must
               accurately describe the fund.

          c.   The name of the single country fund must accurately describe the
               fund.

          d.   An index fund must substantially mirror the index.

                         FUND PARTICIPATION AGREEMENT


     THIS AGREEMENT made as of the 18th day of September, 1998, by and between
NEUBERGER&BERMAN ADVISERS MANAGEMENT TRUST ("TRUST"), a Delaware business trust,
ADVISERS MANAGERS TRUST ("MANAGERS TRUST"), a New York common law trust,
NEUBERGER&BERMAN MANAGEMENT INCORPORATED ("N&B MANAGEMENT"), a New York
corporation, and THE LINCOLN NATIONAL LIFE INSURANCE COMPANY ("LIFE COMPANY"), a
life insurance company organized under the laws of the State of Indiana.

     WHEREAS, TRUST and MANAGERS TRUST are registered with the Securities and
Exchange Commission ("SEC") under the Investment Company Act of 1940, as amended
("40 Act") as open-end, diversified management investment companies; and

     WHEREAS, TRUST is organized as a series fund comprised of several
portfolios ("Portfolios"), the currently available of which are listed on
Appendix A hereto; and

     WHEREAS, MANAGERS TRUST is organized as a series fund, comprised of several
portfolios ("Series"), the currently operational of which are listed on Appendix
A hereto; and

     WHEREAS, each Portfolio of TRUST will invest all of its net investable
assets in a corresponding Series of MANAGERS TRUST; and

     WHEREAS, TRUST was organized to act as the funding vehicle for certain
variable life insurance and/or variable annuity contracts ("Variable Contracts")
offered by life insurance companies through separate accounts of such life
insurance companies ("Participating Insurance Companies") and also offers its
shares to certain qualified pension and retirement plans; and

     WHEREAS, TRUST has received an order from the SEC, dated May 5,1995 (File
No. 812-9164), granting Participating Insurance Companies and their separate
accounts exemptions from the provisions of Sections 9(a), 13(a), 15(a) and 15(b)
of the '40 Act, and Rules 6e-2(b)(15) and 6e-3(T)(b)(15) thereunder, to the
extent necessary to permit shares of the Portfolios of the TRUST to be sold to
and held by variable annuity and variable life insurance separate accounts of
both affiliated and unaffiliated life insurance companies and certain qualified
pension and retirement plans (the "Order"); and

     WHEREAS, LIFE COMPANY has established or will establish one or more
separate accounts ("Separate Accounts") to offer Variable Contracts and is
desirous of having one or more Portfolios of the TRUST as one or more of the
underlying funding vehicles for such Variable Contracts; and
<PAGE>
 
     WHEREAS, N&B MANAGEMENT is registered with the SEC as an investment adviser
under the Investment Advisers Act of 1940, as amended, and as a broker-dealer
under the Securities Exchange Act of 1934, as amended; and

     WHEREAS, N&B MANAGEMENT is the administrator and distributor of the shares
of each Portfolio of TRUST and investment manager of the corresponding Series of
MANAGERS TRUST; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, LIFE COMPANY intends to purchase shares of TRUST to fund the
aforementioned Variable Contracts and TRUST is authorized to sell such shares to
LIFE COMPANY at net asset value;

     NOW, THEREFORE, in consideration of their mutual promises, LIFE COMPANY,
TRUST, MANAGERS TRUST and N&B MANAGEMENT agree as follows:

                        Article I. SALE OF TRUST SHARES

     1.1   TRUST agrees to make available to the Separate Accounts of LIFE
COMPANY shares of the selected Portfolios as listed in Appendix B for investment
of proceeds from Variable Contracts allocated to the designated Separate
Accounts, such shares to be offered as provided in TRUST's Prospectus.

     1.2   TRUST agrees to sell to LIFE COMPANY those shares of the selected
Portfolios of TRUST which LIFE COMPANY orders, executing such orders on a daily
basis at the net asset value next computed after receipt by TRUST or its
designee of the order for the shares of TRUST. For purposes of this Section 1.2,
LIFE COMPANY shall be the designee of TRUST for receipt of such orders from LIFE
COMPANY and receipt by such designee shall constitute receipt by TRUST; provided
that TRUST receives notice of such order by 9:30 a.m. New York time on the next
following Business Day. "Business Day" shall mean any day on which the New York
Stock Exchange is open for trading and on which TRUST calculates its net asset
value pursuant to the rules of the SEC.

     1.3   TRUST agrees to redeem for cash, on LIFE COMPANY's request, any full
or fractional shares of TRUST held by LIFE COMPANY, executing such requests on a
daily basis at the net asset value next computed after receipt by TRUST or its
designee of the request for redemption. For purposes of this Section 1.3, LIFE
COMPANY shall be the designee of TRUST for receipt of requests for redemption
from LIFE COMPANY and receipt by such designee shall constitute receipt by
TRUST; provided that TRUST receives notice of such request for redemption by
9:30 a.m. New York time on the next following Business Day.

                                       2
<PAGE>
 
     1.4   TRUST shall furnish, on or before the ex-dividend date, notice to
LIFE COMPANY of any income dividends or capital gain distributions payable on
the shares of any Portfolio of TRUST. LIFE COMPANY hereby elects to receive all
such income dividends and capital gain distributions as are payable on a
Portfolio's shares in additional shares of the Portfolio. TRUST shall notify
LIFE COMPANY of the number of shares so issued as payment of such dividends and
distributions. LIFE COMPANY reserves the right to elect to receive any such
income dividends or capital gain distributions in cash.

     1.5   TRUST shall make the net asset value per share for the selected
Portfolio(s) available to LIFE COMPANY on a daily basis as soon as reasonably
practicable after the net asset value per share is calculated but shall use its
best efforts to make such net asset value available by 6:00 p.m. New York time.
If TRUST provides LIFE COMPANY with materially incorrect share net asset value
information through no fault of LIFE COMPANY, LIFE COMPANY on behalf of the
Separate Accounts, shall be entitled to an adjustment to the number of shares
purchased or redeemed to reflect the correct share net asset value. Any material
error in the calculation of net asset value per share, dividend or capital gain
information shall be reported promptly upon discovery by TRUST or N&B MANAGEMENT
to LIFE COMPANY.

     1.6   At the end of each Business Day, LIFE COMPANY shall use the
information described in Section 1.5 to calculate Separate Account unit values
for the day. Using these unit values, LIFE COMPANY shall process each such
Business Day's Separate Account transactions based on requests and premiums
received by it by the close of trading on the floor of the New York Stock
Exchange (currently 4:00 p.m. New York time) to determine the net dollar amount
of TRUST shares which shall be purchased or redeemed at that day's closing net
asset value per share. The net purchase or redemption orders so determined shall
be transmitted to TRUST by LIFE COMPANY by 9:30 a.m. New York Time on the
Business Day next following LIFE COMPANY's receipt of such requests and premiums
in accordance with the terms of Sections 1.2 and 1.3 hereof. TRUST shall provide
written confirmations of all purchase or redemption orders of TRUST shares to
LIFE COMPANY by 2:00 p.m. New York time on the Business Day that such purchase
or redemption orders are received by the TRUST in accordance with the terms of
Sections 1.2 and 1.3 hereof.

     1.7   If LIFE COMPANY's order requests the purchase of TRUST shares, LIFE
COMPANY shall pay for such purchase by wiring federal funds to TRUST or its
designated custodial account on the day the order is transmitted by LIFE
COMPANY. If LIFE COMPANY's order requests a net redemption resulting in a
payment of redemption proceeds to LIFE COMPANY, TRUST shall wire the redemption
proceeds to LIFE COMPANY on the day the order is transmitted by LIFE

                                       3
<PAGE>
 
COMPANY, unless doing so would require TRUST to dispose of portfolio securities
or otherwise incur additional costs, but in such event, proceeds shall be wired
to LIFE COMPANY within seven days and TRUST shall notify the person designated
in writing by LIFE COMPANY as the recipient for such notice of such delay by
3:00 p.m. New York Time the same Business Day that LIFE COMPANY transmits the
redemption order to TRUST. If LIFE COMPANY's order requests the application of
redemption proceeds from the redemption of shares to the purchase of shares of
another fund administered or distributed by N&B MANAGEMENT, TRUST shall so apply
such proceeds the same Business Day that LIFE COMPANY transmits such order to
TRUST.

     1.8   Notwithstanding Section 1.7, TRUST reserves the right to suspend the
right of redemption or postpone the date of payment or satisfaction upon
redemption consistent with Section 22(e) of the 40 Act and any rules thereunder.

     1.9   TRUST agrees that all shares of the Portfolios of TRUST will be sold
only to Participating Insurance Companies which have agreed to participate in
TRUST to fund their Separate Accounts and/or to certain qualified pension and
other retirement plans, all in accordance with the requirements of Section
817(h) of the Internal Revenue Code of 1986, as amended ("Code") and Treasury
Regulation 1.817-5. Shares of the Portfolios of TRUST will not be sold directly
to the general public.

     1.10  TRUST may refuse to sell shares of any Portfolio to any person, or
suspend or terminate the offering of the shares of any Portfolio if such action
is required by law or by regulatory authorities having jurisdiction or is, in
the sole discretion of the Board of Trustees of TRUST, acting in good faith and
in light of its fiduciary duties under federal and any applicable state laws,
deemed necessary and in the best interests of the shareholders of such
Portfolios.

                  Article II.  REPRESENTATIONS AND WARRANTIES

     2.1   LIFE COMPANY represents and warrants that it is an insurance company
duly organized and validly existing under the laws of Indiana and that it has

Exchange Act of 1934.

to any issuance or sale of the Variable Contracts, will register each Separate
Account as a unit investment trust ("UIT") in accordance with the provisions of
the '40 Act and cause each Separate Account to remain so registered to

                                       4
<PAGE>
 
serve as a segregated asset account for the Variable Contracts, unless an
exemption from registration is available.

     2.3   LIFE COMPANY represents and warrants that the Variable Contracts will
be registered under the Securities Act of 1933 (the "'33 Act"), unless an
exemption from registration is available, prior to any issuance or sale of the

compliance in all material respects with all applicable federal and state laws,
including any applicable state insurance law suitability requirement.

     2.4   LIFE COMPANY represents and warrants that the Variable Contracts are
currently and at the time of issuance will be treated as life insurance,
endowment or annuity contracts under applicable provisions of the Code, that it
will maintain such treatment and that it will notify TRUST immediately upon
having a reasonable basis for believing that the Variable Contracts have ceased
to be so treated or that they might not be so treated in the future.

     2.5   LIFE COMPANY represents and warrants that it shall deliver such
prospectuses, statements of additional information, proxy statements and
periodic reports of the Trust as may be required to be delivered under
applicable federal or state law and interpretations of federal and state

the diversification requirements set forth in Section 817(h) of the Code, and
the rules and regulations thereunder, including without limitation Treasury
Regulation 1.817-5, and will notify LIFE COMPANY immediately upon having a

the Portfolio to achieve compliance within the grace period afforded by
Regulation 1.817-5.

                                       5
<PAGE>
 
     2.8   TRUST represents and warrants that each Portfolio invested in by the
Separate Account is currently qualified as a "regulated investment company"
under Subchapter M of the Code, that it will make every effort to maintain such

basis for believing it has ceased to so qualify or might not so qualify in the
future.

                 Article III.  PROSPECTUS AND PROXY STATEMENTS

     3.1   TRUST shall prepare and be responsible for filing with the SEC and
any state regulators requiring such filing all shareholder reports, notices,
proxy materials (or similar materials such as voting instruction solicitation
materials), prospectuses and statements of additional information of TRUST.

supplements thereto, to existing Variable Contract owners of LIFE COMPANY:

          (i)     prospectuses and statements of additional information;

          (ii)    annual and semi-annual reports; and

          (iii)   proxy materials.

     LIFE COMPANY will submit any bills for printing, duplicating and/or mailing
costs, relating to the TRUST (or individual Portfolio) documents described
above, to TRUST for reimbursement by TRUST. LIFE COMPANY shall monitor such
costs and shall use its best efforts to control these costs. LIFE COMPANY will
provide TRUST on a semi-annual basis, or more frequently as reasonably requested
by TRUST, with a current tabulation of the number of existing Variable Contract
owners of LIFE COMPANY whose Variable Contract values are invested in TRUST.
This tabulation will be sent to TRUST in the form of a letter signed by a duly
authorized officer of LIFE COMPANY attesting to the accuracy of the information
contained in the letter. If requested by LIFE COMPANY, the TRUST shall provide
such documentation (including a final copy of the TRUST's prospectus as set in
type or in camera-ready copy) and other assistance as is reasonably necessary in
order for LIFE COMPANY to print together in one document the current prospectus
for the Variable Contracts issued by LIFE COMPANY and the current prospectus for
the TRUST. For purposes of

<PAGE>
 
this Article III, if LIFE COMPANY so requests, TRUST will provide a separate
prospectus for each TRUST Portfolio used in a particular Separate Account,
provided such prospectus is contained in the TRUST's currently effective
registration statement. Should LIFE COMPANY wish to print any of these documents
in a format different from that provided by TRUST, LIFE COMPANY shall provide
Trust with sixty (60) days' prior written notice and LIFE COMPANY shall bear the
cost associated with any format change.

     3.3   TRUST will provide, at its expense, LIFE COMPANY with the following
TRUST (or individual Portfolio) documents, and any supplements thereto, with
respect to prospective Variable Contract owners of LIFE COMPANY:

          (i)     camera-ready copy of the current prospectus for printing by
                  the LIFE COMPANY;

          (ii)    camera-ready copies of the individual Portfolio prospectuses
                  filed as part of the TRUST's registration statement;

          (iii)   a copy of the statement of additional information suitable for
                  duplication;

          (iv)    camera-ready copy of proxy material suitable for printing; and

          (v)     camera-ready copy of the annual and semi-annual reports for
                  printing by the LIFE COMPANY.

     3.4   TRUST will provide LIFE COMPANY with at least one complete copy of
all prospectuses, statements of additional information, annual and semi-annual
reports, proxy statements, exemptive applications and all amendments or
supplements to any of the above that relate to the Portfolios within 20 days
after the filing of each such document with the SEC or other regulatory
authority. LIFE COMPANY will provide TRUST with at least one complete copy of
all prospectuses, statements of additional information, annual and semi-annual
reports, proxy statements, exemptive applications and all amendments or
supplements to any of the above that relate to a Separate Account and the TRUST
within 20 days after the filing of each such document with the SEC or other
regulatory authority.

                          Article IV.  SALES MATERIALS

     4.1   LIFE COMPANY will furnish, or will cause to be furnished, to TRUST

<PAGE>
 
prior to its intended use. No such material will be used if TRUST, MANAGERS
TRUST or N&B MANAGEMENT objects to its use in writing within five (5) Business
Days after receipt of such material.

     4.2   TRUST and N&B MANAGEMENT will furnish, or will cause to be furnished,
to LIFE COMPANY, each piece of sales literature or other promotional material in
which LIFE COMPANY or its Separate Accounts are named, at least ten (10)
Business Days prior to its intended use. No such material will be used if LIFE
COMPANY objects to its use in writing within five (5) Business Days after
receipt of such material.

     4.3   TRUST and its affiliates and agents shall not give any information or
make any representations on behalf of LIFE COMPANY or concerning LIFE COMPANY,
the Separate Accounts, or the Variable Contracts issued by LIFE COMPANY, other
than the information or representations contained in a registration statement,
prospectus or offering statement for such Variable Contracts, as such
registration statement, prospectus or offering statement may be amended or
supplemented from time to time, or in reports of the Separate Accounts or
reports prepared for distribution to owners of such Variable Contracts, or in
sales literature or other promotional material approved by LIFE COMPANY or its
designee, except with the written permission of LIFE COMPANY.

     4.4   LIFE COMPANY and its affiliates and agents shall not give any
information or make any representations on behalf of TRUST or concerning TRUST
other than the information or representations contained in a registration
statement or prospectus for TRUST, as such registration statement and prospectus
may be amended or supplemented from time to time, or in sales literature or
other promotional material approved by TRUST or its designee, except with the
written permission of TRUST.

     4.5   For purposes of this Agreement, the phrase "sales literature or other
promotional material" or words of similar import include, without limitation,
advertisements (such as material published, or designed for use, in a newspaper,
magazine or other periodical, radio, television, telephone or tape recording,
videotape display, signs or billboards, motion pictures or other public media),
sales literature (such as any written communication distributed or made
generally available to customers or the public, including brochures, circulars,
research reports, market letters, form letters, seminar texts, or reprints or
excerpts of any other advertisement, sales literature, or published article),
educational or training materials or other communications distributed or made
generally available to some or all agents or employees, registration statements,
prospectuses, statements of additional information, shareholder reports and
proxy materials, and any other material constituting sales

<PAGE>
 
literature or advertising under National Association of Securities Dealers, Inc.
rules, the '40 Act or the '33 Act.

                         Article V. POTENTIAL CONFLICTS

     5.1   The Board of Trustees of TRUST and MANAGERS TRUST (the "Boards") will
monitor TRUST and MANAGERS TRUST, respectively, (collectively the "Funds"), for
the existence of any material irreconcilable conflict between the interests of
the Variable Contract owners of Participating Insurance Company Separate
Accounts investing in the Funds. A material irreconcilable conflict may arise
for a variety of reasons, including: (a) state insurance regulatory authority
action; (b) a change in applicable federal or state insurance, tax, or
securities laws or regulations, or a public ruling, private letter ruling, or
any similar action by insurance, tax, or securities regulatory authorities; (c)
an administrative or judicial decision in any relevant proceeding; (d) the
manner in which the investments of the Funds are being managed; (e) a difference
in voting instructions given by variable annuity and variable life insurance
contract owners or by contract owners of different Participating Insurance
Companies; or (f) a decision by a Participating Insurance Company to disregard
voting instructions of Variable Contract owners.

     5.2   LIFE COMPANY will report any potential or existing conflicts to the
Boards. LIFE COMPANY will provide each appropriate Board with all information
reasonably necessary for it to consider any issues raised in carrying out its
responsibilities under the Conditions set forth in the notice issued by the SEC
for the Funds on April 12, 1995 (the "Notice") (Investment Company Act Release
No. 21003), which LIFE COMPANY has reviewed. LIFE COMPANY will inform each
appropriate Board whenever Variable Contract owner voting instructions are
disregarded by LIFE COMPANY. These responsibilities will be carried out with a
view only to the interests of the Variable Contract owners.

     5.3   If a majority of the Board of a Fund or a majority of its
disinterested trustees or directors, determines that a material irreconcilable
conflict exists, affecting the LIFE COMPANY, LIFE COMPANY, at its expense and to
the extent reasonably practicable (as determined by a majority of disinterested
trustees or directors), will take any steps necessary to remedy or eliminate the
material irreconcilable conflict consistent with the terms and conditions set
forth in the Notice.

     If a material irreconcilable conflict arises because of LIFE COMPANY's
decision to disregard Variable Contract owner voting instructions, and that
decision represents a minority position or would preclude a majority vote, LIFE
COMPANY may be required, at the election of the relevant Fund, to withdraw its
Separate

                                       9
<PAGE>
 
Account's investment in such Fund, and no charge or penalty will be imposed as a
result of such withdrawal. The responsibility to take such remedial action shall
be carried out with a view only to the interests of the Variable Contract
owners.

     For the purposes of this Section 5.3, a majority of the disinterested
members of the applicable Board shall determine whether or not any proposed
action adequately remedies any irreconcilable material conflict, but in no event
will the relevant Fund or N&B MANAGEMENT (or any other investment adviser of the
Funds) be required to establish a new funding medium for any Variable Contract.

     5.4   Any Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly and in
writing to LIFE COMPANY.

     5.5   No less than annually, LIFE COMPANY shall submit to the Boards such
reports, materials or data as such Boards may reasonably request so that the
Boards may fully carry out the obligations imposed upon them by these
Conditions. Such reports, materials, and data shall be submitted more frequently
if deemed appropriate by the applicable Boards, provided that such request shall
not be unreasonable.

                              Article VI.  VOTING

     6.1   LIFE COMPANY will provide pass-through voting privileges to all
Variable Contract owners participating in registered Separate Accounts so long
as the SEC continues to interpret the '40 Act as requiring pass-through voting
privileges for such Variable Contract owners. This condition will apply to UIT-
Separate Accounts investing in TRUST and to managed separate accounts investing
in MANAGERS TRUST to the extent a vote is required with respect to matters
relating to MANAGERS TRUST. Accordingly, LIFE COMPANY, where applicable, will
vote shares of a Fund held in its registered Separate Accounts in a manner
consistent with voting instructions timely received from its Variable Contract
owners. LIFE COMPANY will be responsible for assuring that each of its
registered Separate Accounts that participates in any Fund calculates voting
privileges in a manner consistent with other participants as defined in the
Conditions set forth in the Notice ("Participants"). The obligation to calculate
voting privileges in a manner consistent with all other registered Separate
Accounts investing in a Fund will be a contractual obligation of all
Participants under the agreements governing participation in the Funds. Each
Participant will vote shares held in a given registered Separate Account for
which it has not received timely voting instructions, as well as shares it owns,
in the same proportion as its votes those shares in that Account for which it
has received voting instructions.

     6.2   If and to the extent Rule 6e-2 and Rule 6e-3(T) are amended, or Rule
6e-3 is adopted, to provide exemptive relief from any provision of the '40 Act
or the rules thereunder with respect to mixed and shared funding on terms and
conditions materially different from any exemptions granted in the Order, then
TRUST, MANAGERS TRUST and/or the Participants, as appropriate, shall take such
steps as may be necessary to comply with Rule 6e-2 and Rule 6e-3(T), as amended,
and Rule 6e-3, as adopted, to the extent such Rules are applicable.

                         Article VII.  INDEMNIFICATION

     7.1   Indemnification by LIFE COMPANY.  LIFE COMPANY agrees to indemnify
and hold harmless TRUST, MANAGERS TRUST, N&B MANAGEMENT and each of their
Trustees, directors, officers, employees and agents and each person, if any, who
controls TRUST or MANAGERS TRUST or N&B MANAGEMENT within the meaning of Section
15 of the '33 Act (collectively, the "Indemnified Parties" for purposes of this
Article VII) against any and all losses, claims, damages, liabilities (including
amounts paid in settlement with the written consent of LIFE COMPANY, which
consent shall not be unreasonably withheld) or litigation (including reasonable
legal and other expenses), to which the Indemnified Parties may become subject
under any statute, regulation, at common law or otherwise, insofar as such
losses, claims, damages, liabilities or expenses (or actions in respect thereof)
or settlements are related to the offer, sale or acquisition of TRUST's shares
or the Variable Contracts and:

          (a)  arise out of or are based upon any untrue statements or alleged
               untrue statements of any material fact contained in the
               Registration Statement or prospectus for the Variable Contracts
               or contained in the Variable Contracts (or any amendment or
               supplement to any of the foregoing), or arise out of or are based
               upon the omission or the alleged omission to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, provided that this
               agreement to indemnify shall not apply as to any Indemnified
               Party if such statement or omission or such alleged statement or
               omission was made in reliance upon and in conformity with
               information furnished to LIFE COMPANY by or on behalf of TRUST
               for use in the registration statement or prospectus for the
               Variable Contracts or in the Variable Contracts or sales
               literature (or any amendment or supplement to any of the
               foregoing) or otherwise for use in

                                       11
<PAGE>
 
               connection with the sale of the Variable Contracts or TRUST
               shares; or

          (b)  arise out of or as a result of untrue statements or
               representations (other than statements or representations
               contained in the registration statement, prospectus or sales
               literature of TRUST not supplied by LIFE COMPANY, or persons
               under its control) or wilful misfeasance, bad faith or negligence
               of LIFE COMPANY or persons under its control, with respect to the
               sale or distribution of the Variable Contracts or TRUST shares;
               or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in a registration statement,
               prospectus, or sales literature of TRUST or any amendment thereof
               or supplement thereto or the omission or alleged omission to
               state therein a material fact required to be stated therein or
               necessary to make the statements therein not misleading if such
               statement or omission or such alleged statement or omission was
               made in reliance upon and in conformity with information
               furnished to TRUST for inclusion therein by or on behalf of LIFE
               COMPANY; or

          (d)  arise as a result of any failure by LIFE COMPANY to substantially
               provide the services and furnish the materials under the terms of
               this Agreement; or

          (e)  arise out of or result from any material breach of any
               representation and/or warranty made by LIFE COMPANY in this
               Agreement or arise out of or result from any other material
               breach of this Agreement by LIFE COMPANY.

     7.2   LIFE COMPANY shall not be liable under this indemnification provision
with respect to any losses, claims, damages, liabilities or litigation incurred
or assessed against an Indemnified Party as such may arise from such Indemnified
Party's willful misfeasance, bad faith, or gross negligence in the performance
of such Indemnified Party's duties or by reason of such Indemnified Party's
reckless disregard of obligations or duties under this Agreement or to TRUST,
whichever is applicable.

     7.3   LIFE COMPANY shall not be liable under this indemnification provision
with respect to any claim made against an Indemnified Party unless such
Indemnified Party shall have notified LIFE COMPANY in writing within a
reasonable time after

                                       12
<PAGE>
 
the summons or other first legal process giving information of the nature of the
claim shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify LIFE COMPANY of any such claim shall not relieve
LIFE COMPANY from any liability which it may have to the Indemnified Party
against whom such action is brought otherwise than on account of this
indemnification provision. In case any such action is brought against an
Indemnified Party, LIFE COMPANY shall be entitled to participate at its own
expense in the defense of such action. LIFE COMPANY also shall be entitled to
assume the defense thereof, with counsel reasonably satisfactory to the party
named in the action. After notice from LIFE COMPANY to such party of LIFE
COMPANY's election to assume the defense thereof, the Indemnified Party shall
bear the fees and expenses of any additional counsel retained by it, and LIFE
COMPANY will not be liable to such party under this Agreement for any legal or
other expenses subsequently incurred by such party independently in connection
with the defense thereof other than reasonable costs of investigation.

     7.4  Indemnification by N&B MANAGEMENT.  N&B MANAGEMENT agrees to indemnify
and hold harmless LIFE COMPANY and each of its directors, officers, employees,
and agents and each person, if any, who controls LIFE COMPANY within the meaning
of Section 15 of the '33 Act (collectively, the "Indemnified Parties" for the
purposes of this Article VII) against any and all losses, claims, damages,
liabilities (including amounts paid in settlement with the written consent of
N&B MANAGEMENT which consent shall not be unreasonably withheld) or litigation
(including reasonable legal and other expenses) to which the Indemnified Parties
may become subject under any statute, or regulation, at common law or otherwise,
insofar as such losses, claims, damages, liabilities or expenses (or actions in
respect thereof) or settlements are related to the offer, sale or acquisition of
TRUST's shares or the Variable Contracts and:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the
               registration statement or prospectus or sales literature of TRUST
               (or any amendment or supplement to any of the foregoing), or
               arise out of or are based upon the omission or the alleged
               omission to state therein a material fact required to be stated
               therein or necessary to make the statements therein not
               misleading, provided that this agreement to indemnify shall not
               apply as to any Indemnified Party if such statement or omission
               or such alleged statement or omission was made in reliance upon
               and in conformity with information furnished to N&B MANAGEMENT or
               TRUST by or on

                                       13
<PAGE>
 
               behalf of LIFE COMPANY for use in the registration statement or
               prospectus for TRUST or in sales literature (or any amendment or
               supplement to any of the foregoing) or otherwise for use in
               connection with the sale of the Variable Contracts or TRUST
               shares; or

          (b)  arise out of or as a result of untrue statements or
               representations (other than statements or representations
               contained in the registration statement, prospectus or sales
               literature for the Variable Contracts not supplied by N&B
               MANAGEMENT or persons under its control) or wilful misfeasance,
               bad faith or negligence of TRUST or N&B MANAGEMENT or persons
               under their control, with respect to the sale or distribution of
               the Variable Contracts or TRUST shares; or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in a registration statement,
               prospectus, or sales literature covering the Variable Contracts,
               or any amendment thereof or supplement thereto, or the omission
               or alleged omission to state therein a material fact required to
               be stated therein or necessary to make the statements therein not
               misleading, if such statement or omission or such alleged
               statement or omission was made in reliance upon and in conformity
               with information furnished to LIFE COMPANY for inclusion therein
               by or on behalf of TRUST; or

          (d)  arise as a result of (i) a failure by TRUST to substantially
               provide the services and furnish the materials under the terms of
               this Agreement; or (ii) a failure by a Portfolio(s) invested in
               by the Separate Account to comply with the diversification
               requirements of Section 817(h) of the Code and the regulations
               thereunder; or (iii) a failure by a Portfolio(s) invested in by
               the Separate Account to qualify as a "regulated investment
               company" under Subchapter M of the Code; or

          (e)  arise out of or result from any material breach of any
               representation and/or warranty made by N&B MANAGEMENT in this
               Agreement or arise out of or result from any other material
               breach of this Agreement by N&B MANAGEMENT.

     7.5   N&B MANAGEMENT shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations and duties under this Agreement or to
LIFE COMPANY.

     7.6   N&B MANAGEMENT shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified N&B MANAGEMENT in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify N&B MANAGEMENT of
any such claim shall not relieve N&B MANAGEMENT from any liability which it may
have to the Indemnified Party against whom such action is brought otherwise than
on account of this indemnification provision. In case any such action is brought
against the Indemnified Parties, N&B MANAGEMENT shall be entitled to participate
at its own expense in the defense thereof. N&B MANAGEMENT also shall be entitled
to assume the defense thereof, with counsel satisfactory to the party named in
the action. After notice from N&B MANAGEMENT to such party of N&B MANAGEMENT's
election to assume the defense thereof, the Indemnified Party shall bear the
fees and expenses of any additional counsel retained by it, and N&B MANAGEMENT
will not be liable to such party under this Agreement for any legal or other
expenses subsequently incurred by such party independently in connection with
the defense thereof other than reasonable costs of investigation.

                        Article VIII.  TERM; TERMINATION

     8.1   This Agreement shall be effective as of the date hereof and shall
continue in force until terminated in accordance with the provisions herein.

     8.2   This Agreement shall terminate in accordance with the following
provisions:

          (a)  At the option of LIFE COMPANY or TRUST at any time from the date
               hereof upon 90 days' notice, unless a shorter time is agreed to
               by the parties;

          (b)  At the option of LIFE COMPANY, if TRUST shares are not reasonably
               available to meet the requirements of the Variable Contracts as
               determined by LIFE COMPANY. Prompt notice of election to
               terminate

                                       15
<PAGE>
 
               pursuant to this Section 8.2(b) shall be furnished by LIFE
               COMPANY, said termination to be effective ten days after receipt
               of notice unless TRUST makes available a sufficient number of
               shares to reasonably meet the requirements of the Variable
               Contracts within said ten-day period;

          (c)  At the option of LIFE COMPANY, upon the institution of formal
               proceedings against TRUST or N&B MANAGEMENT by the SEC, or any
               other regulatory body, the expected or anticipated ruling,
               judgment or outcome of which would, in LIFE COMPANY's reasonable
               judgment, materially impair TRUST's ability to meet and perform
               TRUST's obligations and duties hereunder or N&B MANAGEMENT's
               ability to manage any Portfolio. Prompt notice of such election
               to terminate shall be furnished by LIFE COMPANY with said
               termination to be effective upon receipt of notice;

          (d)  At the option of TRUST, upon the institution of formal
               proceedings against LIFE COMPANY by the SEC, the National
               Association of Securities Dealers, Inc., or any other regulatory
               body, the expected or anticipated ruling, judgment or outcome of
               which would, in TRUST's reasonable judgment, materially impair
               LIFE COMPANY's ability to meet and perform its obligations and
               duties hereunder. Prompt notice of election to terminate shall be
               furnished by TRUST with said termination to be effective upon
               receipt of notice;

          (e)  In the event TRUST's shares are not registered, issued or sold in
               accordance with applicable state or federal law, or such law
               precludes the use of such shares as the underlying investment
               medium of Variable Contracts issued or to be issued by LIFE
               COMPANY. Termination shall be effective upon such occurrence
               without notice;

          (f)  At the option of TRUST if the Variable Contracts cease to qualify
               as annuity contracts or life insurance contracts, as applicable,
               under the Code, or if TRUST reasonably believes that the Variable
               Contracts may fail to so qualify. Termination shall be effective
               upon receipt of notice by LIFE COMPANY;

          (g)  At the option of LIFE COMPANY, upon TRUST's breach of any
               material provision of this Agreement, which breach has not been
               cured to the satisfaction of

                                       16
<PAGE>
 
               LIFE COMPANY within ten days after written notice of such breach
               is delivered to TRUST;

          (h)  At the option of TRUST, upon LIFE COMPANY's breach of any
               material provision of this Agreement, which breach has not been
               cured to the satisfaction of TRUST within ten days after written
               notice of such breach is delivered to LIFE COMPANY;

          (i)  At the option of TRUST, if the Variable Contracts are not
               registered (unless an exemption from registration is available),
               issued or sold in accordance with applicable federal and/or state
               law. Termination shall be effective immediately upon such
               occurrence without notice;

          (j)  At the option of LIFE COMPANY, with respect to a Portfolio, upon
               the vote of Variable Contract Owners and written approval of LIFE
               COMPANY to substitute shares of another investment company for
               the shares of any Portfolio in accordance with the terms of the
               Variable Contracts, provided LIFE COMPANY has given TRUST forty-
               five (45) days' notice of the date of such substitution;

          (k)  In the event this Agreement is assigned without the prior written
               consent of LIFE COMPANY, TRUST, MANAGERS TRUST and N&B
               MANAGEMENT, termination shall be effective immediately upon such
               occurrence without notice;

          (l)  At the option of LIFE COMPANY if a Portfolio fails to satisfy the
               diversification requirements set forth in Section 2.7 hereof and
               does not cure such failure within the grace period afforded by
               Regulation 1.817-5. Termination shall be effective immediately
               upon notice.

     8.3   Notwithstanding any termination of this Agreement pursuant to Section
8.2 hereof, TRUST will continue to make available additional TRUST shares
(limited to shares of the Portfolios designated in Appendix B), as provided
below, at the option of LIFE COMPANY for so long as LIFE COMPANY desires
pursuant to the terms and conditions of this Agreement, for all Variable
Contracts in effect on the effective date of termination of this Agreement
(hereinafter referred to as "Existing Contracts"). Specifically, without
limitation, if LIFE COMPANY so elects for TRUST to make additional TRUST shares
available, the owners of the Existing Contracts or LIFE COMPANY, whichever shall
have legal authority to do so, shall be permitted to reallocate investments in
TRUST, redeem investments in TRUST and/or invest in

                                       17
<PAGE>
 
TRUST upon the payment of additional premiums under the Existing Contracts. In
the event of a termination of this Agreement pursuant to Section 8.2 hereof,
LIFE COMPANY, as promptly as is practicable under the circumstances, shall
notify TRUST and N&B MANAGEMENT whether LIFE COMPANY elects for TRUST to
continue to make TRUST shares available after such termination. If TRUST shares
continue to be made available after such termination, the provisions of this
Agreement shall remain in effect. The parties agree that this Section 8.3 shall
not apply to any terminations of this Agreement by the TRUST, MANAGERS TRUST or
N&B MANAGEMENT pursuant to Sections 8.2(f),(h),(i) or (k) hereof.

     8.4   Except as necessary to implement Variable Contract owner initiated
transactions, or as required by state insurance laws or regulations, LIFE
COMPANY shall not redeem the shares attributable to the Variable Contracts (as
opposed to the shares attributable to LIFE COMPANY's assets held in the Separate
Accounts), and LIFE COMPANY shall not prevent Variable Contract owners from
allocating payments to a Portfolio that was otherwise available under the
Variable Contracts, until thirty (30) days after the LIFE COMPANY shall have
notified TRUST of its intention to do so.

                              Article IX.  NOTICES

     Any notice hereunder shall be given by registered or certified mail return

                                     Among
                    THE LINCOLN NATIONAL LIFE INSURANCE CO.
                                      And

                              BARON CAPITAL, INC.


     THIS AGREEMENT, made and entered into this 28th day of August, 1998 by and
among Baron Capital Funds Trust (and all series thereof) a business trust
organized under the laws of the State of Delaware (the "Fund"), and THE LINCOLN
NATIONAL LIFE INSURANCE CO., an Indiana insurance corporation (the "Company"),
on its own behalf and on behalf of each separate account of the Company named in
Schedule 1 to this Agreement as in effect at the time this Agreement is executed
and such other separate accounts that may be added to Schedule 1 from time to
time in accordance with the provisions of Article XI of this Agreement (each
such account referred to as the "Account"), and Baron Capital, Inc. (the
"Distributor").

     WHEREAS, the Fund is engaged in business as an open-end management
investment company and has a class of stock (the "Fund Insurance Shares") that

the owners of such products being referred to as "Product owners") to be offered
by insurance companies which have entered into participation agreements with the
Fund ("Participating Insurance Companies"); and

     WHEREAS, the Fund filed with the Securities and Exchange Commission (the
"SEC") and the SEC has declared effective a registration statement (referred to
herein as the "Fund Registration Statement" and the prospectus contained
therein, or filed pursuant to Rule 497 under the 1933 Act, referred to herein as
the "Fund Prospectus") on Form N-lA to register itself as an open-end management
investment company (File No. 33-40839) under the Investment Company Act of 1940,
as amended (the "1940 Act"), and the Fund Insurance Shares (File No. 811-8505)

<PAGE>
 
     WHEREAS, each Account, a validly existing separate account, duly authorized
by resolution of the Board of Directors of the Company on the date set forth on
Schedule 1, sets aside and invests assets attributable to the Contracts; and

     WHEREAS, the Company has registered or will have registered each Account
with the SEC as a unit investment trust under the 1940 Act before any Contracts
are issued by that Account; and
     
     WHEREAS, the Distributor is registered as a broker-dealer with the SEC
under the Securities Exchange Act of 1934, as amended (the "1934 Act"), and is a
member in good standing of the National Association of Securities Dealers, Inc.
(the "NASD"); and

     WHEREAS, the Distributor and the Fund have entered into an agreement (the
AFund Distribution Agreement") pursuant to which the Distributor will distribute
the Fund Insurance Shares; and

     WHEREAS, BAMCO, Inc. (the "Investment Manager") is registered as an
investment adviser under the 1940 Act and any applicable state securities laws
and serves as an investment manager to the Fund pursuant to an agreement; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, the Company intends to purchase Fund Insurance Shares on behalf of
each Account to fund its Contracts and the Distributor is authorized to sell
such Fund Insurance Shares to unit investment trusts such as the Accounts at net
asset value;

     NOW, THEREFORE, in consideration of their mutual promises, the Company, the
Fund and the Distributor agree as follows:


                       Article I.  SALE OF FUND SHARES
           
     1.1.   The Distributor agrees to sell to the Company those Fund Insurance
Shares, which the Company orders on behalf of each Account, executing such
orders on a daily basis in accordance with Section 1.4 of this Agreement.

                                       2
<PAGE>
 
     1.2.   The Fund agrees to make Fund Insurance Shares available for purchase
by the Company on behalf of each Account at the then applicable net asset value
per share on Business Days as defined in Section 1.4 of this Agreement, and the
Fund shall use its best efforts to calculate and deliver such net asset value by
6:00 p.m., E.S.T., on each such Business Day. Notwithstanding any other
provision in this Agreement to the contrary, the Board of Directors of the Fund
(the "Fund Board") may suspend or terminate the offering of shares, if such
action is required by law or by regulatory authorities having jurisdiction or
if, in the sole discretion of the Fund Board acting in good faith and in light
of its fiduciary duties under Federal and any applicable state laws, suspension
or termination is necessary and in the best interests of the shareholders (it
being understood that "shareholders" for this purpose shall mean Product
owners).

     1.3.   The Fund agrees to redeem, at the Company's request, any full or
fractional Fund Insurance Shares held by each Account or the Company, executing
such requests at the net asset value on a daily basis (Company will expect same
day redemption wires unless unusual circumstances evolve which cause the Fund to
have to redeem securities) in accordance with Section 1.4 of this Agreement, the
applicable provisions of the 1940 Act and the then currently effective Fund
Prospectus. Notwithstanding the foregoing, the Fund may delay redemption of Fund
Insurance Shares of any series to the extent permitted by the 1940 Act, any
rules, regulations or orders thereunder, or the then currently effective Fund
Prospectus.


     1.4. (a)  For purposes of Sections 1.1, 1.2 and 1.3, the Company shall be
               the agent of the Fund for the limited purpose of receiving
               redemption and purchase requests from each Account (but not from
               the general account of the Company), and receipt on any Business
               Day by the Company as such limited agent of the Fund prior to the
               time prescribed in the current Fund Prospectus (which as of the
               date of execution of this Agreement is 4 p.m., E.S.T.) shall
               constitute receipt by the Fund on that same Business Day,
               provided that the Fund, or its designee, receives notice of such
               redemption or purchase request by 11:00 a.m., E.S.T. on the next
               following Business Day. For purposes of this Agreement, "Business
               Day" shall mean any day on which the New York Stock exchange is
               open for trading.

          (b)  The Company shall pay for the shares on the same day that it
               places an order with the Fund to purchase those Fund Insurance
               Shares for an Account. Payment for Fund Insurance Shares will be
               made by each Account or the Company in Federal Funds transmitted
               to the Fund by wire to be received by 11:00 a.m., E.S.T. on the
               day the Fund is properly notified of the purchase order for
               shares. The Fund will confirm receipt of each trade and these
               confirmations will be received by the Company via Fax or Email by
               1:00 p.m. E.S.T. If Federal Funds are not received on time, such
               funds will be invested, and shares purchased thereby will be
               issued, as soon as practicable.

                                       3
<PAGE>
 
          (c)  Payment for shares redeemed by each Account or the Company will
               be made in Federal Funds transmitted to the Company by wire on
               the same day the Fund is notified of the redemption order of
               shares, except that the Fund reserves the right to delay payment
               of redemption proceeds, but in no event may such payment be
               delayed longer than the period permitted under Section 22(e) of
               the 1940 Act. Neither the Fund nor the Distributor shall bear any
               responsibility whatsoever for the proper disbursement or
               crediting of redemption proceeds if securities must be redeemed;
               the Company alone shall be responsible for such action.

     1.5.   Issuance and transfer of Fund Insurance Shares will be by book entry
only. Stock certificates will not be issued to the Company or the Account.
Purchase and redemption orders for Fund Insurance Shares will be recorded in an
appropriate ledger for each Account or the appropriate subaccount of each
Account.

     1.6.   The Fund shall furnish notice as soon as reasonably practicable to
the Company of any income dividends or capital gain distributions payable on any
shares. The Company, on its behalf and on behalf of each Account, hereby elects
to receive all such dividends and distributions as are payable on any Fund
Insurance Shares in the form of additional shares. The Company reserves the
right, on its behalf and on behalf of each Account, to revoke this election and
to receive all such dividends in cash. The Fund shall notify the Company of the
number of Fund Insurance Shares so issued as payment of such dividends and
distributions.

     1.7.   The Fund shall use its best efforts to make the net asset value per
share available to the Company by 6 p.m., E.S.T. each Business Day, and in any
event, as soon as reasonably practicable after the net asset value per share is
calculated, and shall calculate such net asset value in accordance with the then
currently effective Fund Prospectus. Neither the Fund, any Series, the
Distributor, nor the Investment Manager nor any of their affiliates shall be
liable for any information provided to the Company pursuant to this Agreement
which information is based on incorrect information supplied by the Company to
the Fund, the Distributor or the Investment Manager.

     1.8. (a)  The Company may withdraw each Account's investment in the Fund
               only: (i) as necessary to facilitate Contract owner requests;
               (ii) upon a determination by a majority of the Fund Board, or a
               majority of disinterested Fund Board members, that an
               irreconcilable material conflict exists among the interests of
               (x) any Product Owners or (y) the interests of the Participating
               Insurance Companies investing in the Fund; (iii) upon requisite
               vote of the Contractowners having an interest in the affected
               Fund to substitute the shares of another investment company for
               shares in accordance with the terms of the Contracts; (iv) as
               required by state and/or federal laws or regulations or judicial
               or other legal precedent of general application; or (v) at the
               Company's sole discretion, pursuant to an order of the SEC under
               Section 26(b) of the 1940 Act.

                                        4                                      
<PAGE>
 
          (b)  The parties hereto acknowledge that the arrangement contemplated
               by this Agreement is not exclusive and that the Fund Insurance
               Shares may be sold to other insurance companies (subject to
               Section 1.9 hereof) and the cash value of the Contracts may be
               invested in other investment companies.

          (c)  The Company shall not, without prior notice to the Distributor
               (unless otherwise required by applicable law), take any action to
               operate each Account as a management investment company under the
               1940 Act.

     1.9.   The Fund and the Distributor agree that Fund Insurance Shares will
be sold only to Participating Insurance Companies and their separate accounts.
The Fund and the Distributor will not sell Fund Insurance Shares to any
insurance company or separate account unless an agreement complying with Article
VII of this Agreement is in effect to govern such sales. No Fund Insurance
Shares will be sold to the general public.

                  Article II.  REPRESENTATIONS AND WARRANTIES

     2.1.   The Company represents and warrants (a) that the Contracts are

it has ceased to so qualify or that it might not so qualify in the future.

     2.4.   The Fund represents and warrants that it will comply with Section

believing that the Contracts have ceased to be so treated or that they might not
be so treated in the future.

expenses, and operations are and shall at all times remain in material

perform this Agreement; and with any state- mandated investment restrictions set

   Article III.  PROSSPECTUSES AND PROXY STATEMENTS; SALES MATERIAL AND OTHER
                                  INFORMATION                                  

     3.1.   The Distributor shall provide the Company with as many copies of the
current Fund Prospectus as the Company may reasonably request. If requested by
the Company in lieu thereof, the Fund at its expense shall provide to the
Company a camera-ready copy, and electronic version, of the current Fund
Prospectus suitable for printing and other assistance as is reasonably necessary
in order for the Company to have a new Contracts Prospectus printed together
with the Fund Prospectus in one document. See Article V for a detailed
explanation of the responsibility for the cost of printing and distributing Fund
prospectuses .

Information for the Fund is available from the Distributor (or, in the Fund's
discretion, the Fund Prospectus shall state that such Statement is available
from the Fund), and the Distributor (or the Fund) shall provide such Statement
free of charge to the Company and to any outstanding or prospective Contract
owner who requests such Statement.

     3.3. (a)  The Fund at its expense shall be responsible for preparing,
               printing and distributing its proxy material. The Company will
               provide the appropriate Contractowner names and addresses to the

     3.4.    The Company shall furnish each piece of sales literature or other
promotional material in which the Fund or the Investment Manager is named to
theFund or the Distributor prior to its use. No such material shall be used,
except with the prior written permission of the Fund or the Distributor. The

prompt and timely basis. Failure of the Fund to respond within 10 days of the
request by the Company shall relieve the Company of the obligation to obtain the
prior written permission of the Fund or the Distributor.

be amended or supplemented from time to time, or in reports or proxy statements
for the Fund, or in sales literature or other promotional material approved by
the Fund or by the Distributor, except with the prior written permission of the
Fund or the Distributor. The Fund agrees to respond to any request for
permission on a prompt and timely basis. If neither the Fund nor the Distributor
responds within 10 days of a request by the Company, then the Company shall be
relieved of the obligation to obtain the prior written permission of the Fund.

required by applicable securities laws of the various states.

     6.4.   The Company shall be responsible for assuring that any prospectus
offering a Contract that is a life insurance contract where it is reasonably

circumstances under which a Contract could be treated as a modified endowment
contract (or policy).

     6.5.   To the extent that it decides to finance distribution expenses
pursuant to Rule 12b-1, the Fund undertakes to have a Fund Board of Directors, a

          (b)  Should the Fund or the Distributor become aware of any
               restrictions which may be appropriate for inclusion in Schedule

               those restrictions.
              
                       Article VII.  POTENTIAL CONFLICTS
              
     7.1.   The Company has reviewed a copy of the order (the "Mixed and Shared
Funding Order") dated June 16, 1998 of the Securities and Exchange Commission
under Section 6c of the Act and, in particular, has reviewed the conditions to
the relief set forth in the related Notice. As set forth therein, the Company
agrees to report to the Board of Directors of the Fund (the "Board") any
potential or existing conflicts between the interests of Product Owners of all
separate accounts investing in the Fund, and to assist the Board in carrying out
its responsibilities under the conditions of the Mixed and Shared Funding Order
by providing all information reasonably necessary for the Board to consider any
issues raised, including information as to a decision to disregard voting
instructions of variable contract owners.

     7.2.   If a majority of the Board, or a majority of disinterested Board
Members, determines that a material irreconcilable conflict exists, the Board
shall give prompt notice to all Participating Insurance Companies.


          (a)  If a majority of the whole Board, after notice to the Company and
               a reasonable opportunity for the Company to appear before it and
               present its case, determines that the Company is responsible for
               said conflict, and if the Company agrees with that determination,
               the Company shall, at its sole cost and expense, take whatever
               steps are necessary to remedy the irreconcilable material
               conflict. These steps could include: (a) withdrawing the assets
               allocable to some or all of the affected Accounts from the Fund
               and reinvesting such assets in a different investment vehicle, or
               submitting the question of whether such segregation should be
               implemented to a vote of all affected Contractowners and, as
               appropriate, segregating the assets of any particular group
               (i.e., variable annuity Contractowners, variable life insurance
               policyowners, or variable Contractowners of one or more
               Participating Insurance Companies) that votes in favor of such
               segregation, or offering to the affected Contractowners the
               option of making such a change; and (b) establishing a new
               registered mutual fund or management separate account, or taking
               such other action as is necessary to remedy or eliminate the
               irreconcilable material conflict.



          (b)  If the Company disagrees with the Board's determination, the
               Company shall file a written protest with the Board, reserving
               its right to dispute the determination as between just the
               Company and the Fund. After reserving that right the Company,
               although disagreeing with the Board that it (the Company) was
               responsible for the conflict, shall take the necessary steps,
               under protest, to remedy


                                     

                                       11
<PAGE>
 
               the conflict, substantially in accordance with paragraph (a) just
               above, for the protection of Contractowners.


          (c)  As between the Company and the Fund, if within 45 days after the
               Board's determination the Company elects to press the dispute, it
               shall so notify the Board in writing. The parties shall then
               attempt to resolve the matter amicably through negotiation by
               individuals from each party who are authorized to settle the
               matter.

               If the matter has not been amicably resolved within 60 days from
               the date of the Company's notice of its intent to press the
               dispute, hen before either party shall undertake to litigate the
               dispute it shall be submitted to non-binding arbitration
               conducted expeditiously in accordance with the CPR Rules for Non-
               Administered Arbitration of Business Disputes, by a sole
               arbitrator; provided, however, that if one party has requested
               the other party to seek an amicable resolution and the other
               party has failed to participate, the requesting party may
               initiate arbitration before expiration of the 60-day period set
               out just above.



               If within 45 days of the commencement of the process to select an
               arbitrator the parties cannot agree upon the arbitrator, then he
               or she will be selected from the CPR Panels of Neutrals. The
               arbitration shall be governed by the United States Arbitration
               Act, 9 U.S.C. Sec. 1-16. The place of arbitration shall be Fort
               Wayne, Indiana. The Arbitrator is not empowered to award damages
               in excess of compensatory damages.



          (d)  If the Board shall determine that the Fund or another insurer was
               responsible for the conflict, then the Board shall notify the
               Company immediately of that determination. The Fund shall assure
               the Company that it (the Fund) or that other insurer, as
               applicable, shall, at its sole cost and expense, take whatever
               steps are necessary to eliminate the conflict.


     7.3.   If a material irreconcilable conflict arises because of the
Company's decision to disregard Contractowner voting instructions and that
decision represents a minority position or would preclude a majority vote, the
Company shall withdraw (without charge or penalty) each Account's investment in
the Fund, if the Fund so elects.

     7.4.   Subject to the terms of Section 7.2 above, the Company shall carry
out the responsibility to take remedial action in the event of a Board
determination of an irreconcilable material conflict with a view only to the
interests of Contractowners.

     7.5.   For purposes of this Article, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable conflict, but in no event will the Fund
be required to establish a new funding medium for any variable contract, nor
will the Company be required to establish a new funding medium for any

                                     

                                       12

Contract if in either case an offer to do so has been declined by a vote of a
majority of affected Contractowners.

                        Article VIII.  INDEMNIFICATION

     8.1.   Indemnification by the Company.  The Company agrees to indemnify
and hold harmless the Fund, the Distributor and each person who controls or is
associated with the Fund (other than another Participating Insurance Company) or
the Distributor within the meaning of such terms under the federal securities
laws and any officer, trustee, director, employee or agent of the foregoing,
against any and all losses, claims, damages or liabilities, joint or several
(including any investigative, legal and other expenses reasonably incurred in
connection with, and any amounts paid in settlement of, any action, suit or
proceeding or any claim asserted), to which they or any of them may become
subject under any statute or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Contracts
               Registration Statement, Contracts Prospectus, sales literature or
               other promotional material for the Contracts or the Contracts
               themselves (or any amendment or supplement to any of the
               foregoing), or arise out of or are based upon the omission or the
               alleged omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading in light of the circumstances in which they were made;
               provided that this obligation to indemnify shall not apply if
               such statement or omission or such alleged statement or alleged
               omission was made in reliance upon and in conformity with
               information furnished in writing to the Company by the Fund or
               the Distributor (or a person authorized in writing to do so on
               behalf of the Fund or the Distributor) for use in the Contracts
               Registration Statement, Contracts Prospectus or in the Contracts
               or sales literature (or any amendment or supplement) or otherwise
               for use in connection with the sale of the Contracts or Fund
               Insurance Shares; or

          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact by or on behalf of the
               Company (other than statements or representations contained in
               the Fund Registration Statement, Fund Prospectus or sales
               literature or other promotional material of the Fund not supplied
               by the Company or persons under its control) or wrongful conduct
               of the Company or persons under its control with respect to the
               sale or distribution of the Contracts or Fund Insurance Shares;
               or

          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Fund Registration Statement,
               Fund Prospectus or sales literature or other promotional material
               of the Fund or any amendment thereof or supplement thereto, or
               the omission or alleged omission to state therein a
               
                                      13
<PAGE>
 
               material fact required to be stated therein or necessary to make
               the statements therein not misleading in light of the
               circumstances in which they were made, if such statement or
               omission was made in reliance upon and in conformity with
               information furnished to the Fund by or on behalf of the Company;
               or
               
          (d)  arise as a result of any failure by the Company to provide the
               services and furnish the materials or to make any payments under
               the terms of this Agreement; or

          (e)  arise out of any material breach by the Company of this
               Agreement, including but not limited to any failure to transmit a
               request for redemption or purchase of Fund Insurance Shares on a
               timely basis in accordance with the procedures set forth in
               Article 1; or

          (f)  arise as a result of the Company's providing the Fund with
               inaccurate information, which causes the Fund to calculate its
               Net Asset Values incorrectly.

This indemnification will be in addition to any liability which the Company may
otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.2.   Indemnification by the Distributor.  The Distributor agrees to
indemnify and hold harmless the Company and each person who controls or is
associated with the Company within the meaning of such terms under the federal
securities laws and any officer, director, employee or agent of the foregoing,
against any and all losses, claims, damages or liabilities, joint or several
(including any investigative, legal and other expenses reasonably incurred in
connection with, and any amounts paid in settlement of, any action, suit or
proceeding or any claim asserted), to which they or any of them may become
subject under any statute or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities:

          (a)  arise out of or are based upon any untrue statement or alleged
               untrue statement of any material fact contained in the Fund
               Registration Statement, Fund Prospectus (or any amendment or
               supplement thereto) or sales literature or other promotional
               material of the Fund, or arise out of or are based upon the
               omission or the alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in light of the circumstances in which
               they were made; provided that this obligation to indemnify shall
               not apply if such statement or omission or alleged statement or
               alleged omission was made in reliance upon and in conformity with
               information furnished in writing by the Company to the Fund or
               the Distributor for use in the Fund

               Insurance Shares; or
               
          (b)  arise out of or are based upon any untrue statement or alleged
               untrue statement of a material fact made by the Distributor or
               the Fund (other than statements or representations contained in
               the Fund Registration Statement, Fund Prospectus or sales
               literature or other promotional material of the Fund not supplied
               by the Distributor or the Fund or persons under their control) or
               wrongful conduct of the Distributor or persons under its control
               with respect to the sale or distribution of the Contracts or Fund
               Insurance Shares; or
               
          (c)  arise out of any untrue statement or alleged untrue statement of
               a material fact contained in the Contract's Registration
               Statement, Contracts Prospectus or sales literature or other
               promotional material for the Contracts (or any amendment or
               supplement thereto), or the omission or alleged omission to state
               therein a material fact required to be stated therein or
               necessary to make the statements therein not misleading in light
               of the circumstances in which they were made, if such statement
               or omission was made in reliance upon information furnished in
               writing by the Distributor or the Fund to the Company (or a
               person authorized in writing to do so on behalf of the Fund or
               the Distributor); or

          (d)  arise as a result of any failure by the Fund to provide the
               services and furnish the materials under the terms of this
               Agreement (including, but not by way of limitation, a failure,
               whether unintentional or in good faith or otherwise: (i) to
               comply with the diversification requirements specified in Article
               VI of this Agreement; and (ii) to provide the Company with
               accurate information sufficient for it to calculate its
               accumulation and/or annuity unit values in timely fashion as
               required by law and by the Contracts Prospectuses); or

          (e)  arise out of any material breach by the Distributor or the
               Fund of this Agreement.

This indemnification will be in addition to any liability which the Distributor
may otherwise have; provided, however, that no party shall be entitled to
indemnification if such loss, claim, damage or liability is due to the willful
misfeasance, bad faith, gross negligence or reckless disregard of duty by the
party seeking indemnification.

     8.3.   Indemnification Procedures.  After receipt by a party entitled to
indemnification ("indemnified party") under this Article VIII of notice of the
commencement of any action, if a claim in respect thereof is to be made by the
indemnified party against any person obligated to provide indemnification under
this Article VIII ("indemnifying party"), such indemnified party will notify the
indemnifying party in writing of the commencement thereof as soon as practicable


                                      

                                       15

thereafter, provided that the omission to so notify the indemnifying party will
not relieve it from any liability under this Article VIII, except to the extent
that the omission results in a failure of actual notice to the indemnifying
party and such indemnifying party is damaged solely as a result of the failure
to give such notice.  The indemnifying party, upon the request of the
indemnified party shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding.  In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment.

     A successor by law of the parties to this Agreement shall be entitled to
the benefits of the indemnification contained in this Article VIII.  The
indemnification provisions contained in this Article VIII shall survive any
termination of this Agreement.

                          Article IX. APPLICABLE LAW

     9.1.   This Agreement shall be construed and the provisions hereof
interpreted under and in accordance with the laws of the state of Indiana,
without giving effect to the principles of conflicts of laws.

     9.2.   This Agreement shall be subject to the provisions of the 1933,
1934 and 1940 Acts, and the rules and regulations and rulings thereunder,
including such exemptions from those statutes, rules and regulations as the SEC
may grant, and the terms hereof shall be limited, interpreted and construed in
accordance therewith.

     10.1.   This Agreement shall terminate:

          (a)  at the option of any party upon 120 days advance written notice

               available to meet the requirements of the Contracts as determined

               such cause shall be furnished by the Company. Termination shall
               be effective ten days after the giving of notice by the Company;

          (c)  at the option of the Fund upon institution of formal proceedings
               against the Company by the NASD, the SEC, the insurance
               commission of any state or any other regulatory body regarding
               the Company's duties under this Agreement or related to the sale
               of the Contracts, the operation of each Account, the
               administration of the Contracts or the purchase of Fund Insurance
               Shares, or an expected or anticipated ruling, judgment or outcome
               which would, in the Fund's reasonable judgment, materially impair
               the Company's ability to perform the Company's obligations and
               duties hereunder; or

          (d)  at the option of the Company upon institution of formal
               proceedings against the Fund, the Distributor, the Investment

               any state securities or insurance commission or any other
               regulatory body regarding the duties of the Fund or the
               Distributor under this Agreement, or an expected or anticipated
               ruling, judgment or outcome which would, in the Company's
               reasonable judgment, materially impair the Fund's or the
               Distributor's ability to perform Fund's or Distributor's
               obligations and duties hereunder; or

          (e)  at the option of the Company upon institution of formal
               proceedings against the Investment Manager or Sub-investment
               Manager by the NASD, the SEC, or any state securities or
               insurance commission or any other regulatory body which would, in
               the good faith opinion of the Company, result in material harm to
               the Accounts, the Company, or Contractowners.

          (f)  upon requisite vote of the Contract owners having an interest in
               the affected Series (unless otherwise required by applicable law)
               and written approval of the Company, to substitute the shares of
               another investment company for the corresponding shares of the
               Fund in accordance with the terms of the Contracts; or

          (g)  at the option of the Fund in the event any of the Contracts are

               Federal and/or state law; or

                                        17
<PAGE>
 
          (h)  at the option of the Company or the Fund upon a determination by
               a majority of the Fund Board, or a majority of disinterested Fund
               Board members, that an irreconcilable material conflict exists
               among the interests of (i) any Product owners or (ii) the
               interests of the Participating Insurance Companies investing in
               the Fund; or

          (i)  at the option of the Company if the Fund ceases to qualify as a
               Regulated Investment Company under Subchapter M of the Code, or
               under any successor or similar provision, or if the Company
               reasonably believes, based on an opinion of its counsel, that the
               Fund may fail to so qualify; or

          (j)  at the option of the Company if the Fund fails to meet the
               diversification requirements specified in Section 817(h) of the
               Code and any regulations thereunder; or

          (k)  at the option of the Fund if the Contracts cease to qualify as
               annuity contracts or life insurance policies, as applicable,
               under the Code, or if the Fund reasonably believes that the
               Contracts may fail to so qualify; or

          (l)  at the option of either the Fund or the Distributor if the Fund
               or the Distributor, respectively, shall determine, in their sole
               judgment exercised in good faith, that either (1) the Company
               shall have suffered a material adverse change in its business or
               financial condition; or (2) the Company shall have been the
               subject of material adverse publicity which is likely to have a
               material adverse impact upon the business and operations of
               either the Fund or the Distributor; or

          (m)  at the option of the Company, if the Company shall determine, in
               its sole judgment exercised in good faith, that either: (1) the
               Fund and the Distributor, or either of them, shall have suffered
               a material adverse change in their respective businesses or
               financial condition; or (2) the Fund or the Distributor, or both
               of them, shall have been the subject of material adverse
               publicity which is likely to have a material adverse impact upon
               the business and operations of the Company; or

          (n)  upon the assignment of this Agreement (including, without
               limitation, any transfer of the Contracts or the Accounts to
               another insurance company pursuant to an assumption reinsurance
               agreement) unless the non-assigning party consents thereto or
               unless this Agreement is assigned to an affiliate of the
               Distributor.

     10.2.   Notice Requirement.  Except as otherwise provided in Section 10.1,
no termination of this Agreement shall be effective unless and until the party
terminating this Agreement gives prior written notice to all other parties to
this Agreement of its intent to terminate which notice shall set forth the basis
for such termination.  Furthermore:
                                      

                                       18
<PAGE>
 
          (a)  In the event that any termination is based upon the provisions of
               Article VII or the provisions of Section 10.1(a) of this
               Agreement, such prior written notice shall be given in advance of
               the effective date of termination as required by such provisions;
               and

          (b)  in the event that any termination is based upon the provisions of
               Section 10.1(c) or 10.1(d) of this Agreement, such prior written
               notice shall be given at least ninety (90) days before the
               effective date of termination, or sooner if required by law or
               regulation.

          (c)  in the event that any termination is based upon the provisions of
               Section 10.1(e) of this Agreement, such prior written notice
               shall be given at least sixty (60) days before the date of any
               proposed vote to replace the Fund's shares

     10.3.   Effect of Termination
            
          (a)  Notwithstanding any termination of this Agreement pursuant to
               Section 10.1 of this Agreement, the Fund and the Distributor
               will, at the option of the Company, continue to make available
               additional Fund Insurance Shares for so long after the
               termination of this Agreement as the Company desires, pursuant to
               the terms and conditions of this Agreement as provided in
               paragraph (b) below, for all Contracts in effect on the effective
               date of termination of this Agreement (hereinafter referred to as
               "Existing Contracts"). Specifically, without limitation, if the
               Company so elects to make additional Fund Insurance Shares
               available, the owners of the Existing Contracts or the Company,
               whichever shall have legal authority to do so, shall be permitted
               to reallocate investments in the Fund, redeem investments in the
               Fund and/or invest in the Fund upon the making of additional
               purchase payments under the Existing Contracts.

          (b)  In the event of a termination of this Agreement pursuant to
               Section 10.1 of this Agreement, the Fund and the Distributor
               shall promptly notify the Company whether the Distributor and the
               Fund will continue to make Fund Insurance Shares available after
               such termination. If Fund Insurance Shares continue to be made
               available after such termination, the provisions of this
               Agreement shall remain in effect except for Section 10.1(a) and
               thereafter either the Fund or the Company may terminate the
               Agreement, as so continued pursuant to this Section 10.3, upon
               prior written notice to the other party, such notice to be for a
               period that is reasonable under the circumstances but, if given
               by the Fund, need not be for more than six months.
               
          (c)  The parties agree that this Section 10.3 shall not apply to any
               termination made pursuant to Article VII or any conditions or
               undertakings incorporated by reference in Article VII, and the
               effect of such Article VII termination shall be governed by the
               provisions set forth or incorporated by reference therein.

                     State-mandated Investment Restrictions
                             Applicable to the Fund
                             As of August 28, 1998


The California Department of Insurance has established the following Guidelines
for an underlying portfolio of a Separate Account:

Borrowing.  Borrowing limits for any variable contract separate account
portfolio are (1) 10% of net asset value when borrowing for any general purpose;
and (2) 25% of net asset value when borrowing as a temporary measure to
facilitate redemptions. Net asset value of a portfolio is the market value of
all investments or assets owned less outstanding liabilities of the portfolio at
the time that any new or additional borrowing is undertaken.

Foreign Investments - Diversification.

1.   A portfolio will be invested in a minimum of five different foreign
countries at all times.

However, this minimum is reduced to four when foreign investments comprise less
than 80% of the portfolio's net asset value; to three when less than 60% of that
value; to two when less than 40%; and to one when less than 20%.

2.   Except as set forth in items 3 and 4 below, a Portfolio will have no more
than 20% of its net asset value invested in securities of issuers located in any
one country.

3.   A Portfolio may have an additional 15% of its net asset value invested in
securities of issuers located in any one of the following countries: Australia,
Canada, France, Japan, the United Kingdom or Germany.

4.   A Portfolio's investments in United States issuers are not subject to the
