         Cova and Lord, Abbett & Co., (the Fund's Investment Manager) each made
         initial capital contributions to the Fund and together own the majority
         of the outstanding shares of the Fund.

         COVA Variable Annuity Account One, a separate account of COVA Financial
         Services Life Insurance Company is a Delaware corporation located at
         One Tower Lane, Oakbrook Terrace, Illinois 60181.

         Great American Reserve Insurance Company is a life insurance company
         organized under the laws of the State of Indiana located at 11815 N.
         Pennsylvania Street, Carmel, Indiana 46032-4572.

         Lord, Abbett & Co. is a partnership located at The General Motors
         Building, 767 Fifth Avenue, New York, New York 10153-0203. Eight of the

Item 26. Number of Record Holders of Securities

         The Life Companies and Lord, Abbett & Co. are the shareholders of the
         Fund.

Item 27. Indemnification

         Registrant is incorporated under the laws of the State of Maryland and
         is subject to Section 2-418 of the Corporations and Associations
         Article of the Annotated Code of the State of Maryland controlling the
         indemnification of the directors and officers. Since Registrant has its
         executive offices in the State of New York, and is qualified as a
         foreign corporation doing business in such State, the persons covered
         by the foregoing statute may also be entitled to and subject to the
         limitations of the indemnification provisions of Section 721-726 of the
         New York Business Corporation Law.

         The general effect of these statutes is to protect officers, directors
         and employees of Registrant against legal liability and expenses
         incurred by reason of their positions with the Registrant. The statutes
         provide for indemnification for liability
<PAGE>

Part C
Page 3


         for proceedings not brought on behalf of the corporation and for those
         brought on behalf of the corporation, and in each case place conditions
         under which indemnification will be permitted, including requirements
         that the officer, director or employee acted in good faith. Under
         certain conditions, payment of expenses in advance of final disposition
         may be permitted. The By-Laws of Registrant, without limiting the
         authority of Registrant to indemnify any of its officers, employees or
         agents to the extent consistent with applicable law, makes the
         indemnification of its directors mandatory subject only to the
         conditions and limitations imposed by the above-mentioned Section 2-418
         of Maryland Law and by the provisions of Section 17(h) of the
         Investment Company Act of 1940 as interpreted and required to be
         implemented by SEC Release No. IC-11330 of September 4, 1980.

         In referring in its By-Laws to, and making indemnification of directors
         subject to the conditions and limitations of, both Section 2-418 of the
         Maryland Law and Section 17(h) of the Investment Company Act of 1940,
         Registrant intends that conditions and limitations on the extent of the
         indemnification of directors imposed by the provisions of either
         Section 2-418 or Section 17(h) shall apply and that any inconsistency
         between the two will be resolved by applying the provisions of said
         Section 17(h) if the condition or limitation imposed by Section 17(h)
         is the more stringent. In referring in its By-Laws to SEC Release No.
         IC-11330 as the source for interpretation and implementation of said
         Section 17(h), Registrant understands that it would be required under
         its By-Laws to use reasonable and fair means in determining whether
         indemnification of a director should be made and undertakes to use
         either (1) a final decision on the merits by a court or other body
         before whom the proceeding was brought that the person to be
         indemnified ("indemnitee") was not liable to Registrant or to its
         security holders by reason of willful malfeasance, bad faith, gross
         negligence, or reckless disregard of the duties involved in the conduct
         of his office ("disabling conduct") or (2) in the absence of such a
         decision, a reasonable determination, based upon a review of the facts,
         that the indemnitee was not liable by reason of such disabling conduct,
         by (a) the vote of a majority of a quorum of directors who are neither
         "interested persons" (as defined in the 1940 Act) of Registrant nor
         parties to the proceeding, or (b) an independent legal counsel in a
         written opinion. Also, Registrant will make advances of attorneys' fees
         or other expenses incurred by a director in his defense only if (in
         addition to his undertaking to repay the advance if he is not
         ultimately entitled to indemnification) (1) the indemnitee provides a
         security for his undertaking, (2) Registrant shall be insured against
         losses arising by reason of any lawful advances, or (3) a majority of a
         quorum of the non-interested, non-party directors of Registrant, or an
         independent legal counsel in a written opinion, shall determine, based
         on a review of readily available facts, that there is reason to believe
         that the indemnitee ultimately will be found entitled to
         indemnification.
<PAGE>

Part C
Page 4


         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 Act and is, therefore, unenforceable.
         In the event that a claim for indemnification against such liabilities
         (other than the payment by the Registrant of expense 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 Act
         and will be governed by the final adjudication of such issue.

         In addition, Registrant maintains a directors' and officers errors and
         omissions liability insurance policy protecting directors and officers
         against liability for breach of duty, negligent act, error or omission
         committed in their capacity as directors or officers. The policy
         contains certain exclusions, among which is exclusion from coverage for
         active or deliberate dishonest or fraudulent acts and exclusion for
         fines or penalties imposed by law or other matters deemed uninsurable.

Item 28. Business and Other Connections of Investment Adviser

         Lord, Abbett & Co. acts as investment adviser for twelve other open-end
         investment companies and as investment adviser to approximately 6,220

2. THE FUND
- --------------------------------------------------------------------------------

The Fund is a diversified open-end management investment company incorporated
under the laws of Maryland on August 28, 1989. The Fund is a series fund
currently comprised of one active Portfolio: the Growth and Income Portfolio
(the "Portfolio"). The Portfolio issues one separate class of shares: the
Variable Contract Class which is offered by this Prospectus. Each share of
common stock of the Fund, regardless of Class, has a par value of $.001 per
share and has one vote and an equal right to dividends and distributions with
respect to the Portfolio, except as to those dividends and distributions which
are affected by expenses unique to a class. All shares have noncumulative voting
rights for the election of Directors. Each share is fully paid, nonassessable
and freely transferable. There are no liquidation, conversion or preemptive
rights. The fiscal year-end of the Fund is December 31.

Distribution of Fund Shares

Lord Abbett Distributor LLC ("Lord Abbett Distributor"), located at The General
Motors Building, 767 Fifth Avenue, New York, New York 10153-0203, is the
distributor of the shares of the Portfolio. The Board of Directors of the Fund
has adopted a distribution plan (the "Plan") pursuant to Rule 12b-1 under the
Investment Company Act of 1940, as amended (the "1940 Act"), for the shares,
which has been approved by the shareholders of the Portfolio. The Plan has not
been activated to date. Under the Plan, the Variable Contract Class (the
"Class") of the Portfolio may bear certain costs of distributing shares in
accordance with the Plan. (See "Distribution Plan" below.) Shares of the Class
(the "shares") are currently issued and redeemed only in connection with
investment in and payments under certain variable annuity contracts issued by
life insurance companies and their affiliates ("Life Companies"). The shares are
purchased and redeemed at net asset value. Lord Abbett Distributor and the Fund
each reserves the right to suspend, change or withdraw the offering of shares of
any Portfolio or Portfolios or any of the terms of such offering.

Distribution Plan

Pursuant to the Plan, the Fund, on behalf of the Class, may make payments to
Lord Abbett Distributor for remittance to a Life Company for certain
distribution expenses incurred or paid by such Life Company, provided that such
remittances in the aggregate do not exceed 0.15 of 1%, on an annual basis, of
the average daily net asset value of shares of the Portfolio sold to such Life
Company to be used as the underlying investment for variable life insurance and
variable annuity contracts ("Variable Contracts"). For the year ended December
31, 1997, no payments were made pursuant to the Plan.

Distribution expenses for which a Life Company may be reimbursed include, but
are not limited to, expenses of printing and distributing Fund prospectuses,
statements of 


                                      -3-
<PAGE>

additional information and shareholder reports to existing and potential
Variable Contract owners and developing and preparing Fund advertisements and
other promotional materials designed to promote the distribution of shares. Lord
Abbett will be required to submit to the Directors for approval annual
distribution expense budgets and quarterly reports of, and requests for payment
of, distribution expenses as to the Portfolio.

Variable annuity contract owners should refer to the fee table section of their
separate account prospectuses for further information with respect to the effect
of the Plan on their annuity contract expenses.

3. INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------

The Portfolio of the Fund has an investment objective that it pursues through
investment policies as described below. The Portfolio is managed by Lord, Abbett
& Co. ("Lord Abbett") and its risks and opportunities should be carefully
examined. There is no assurance that the investment objective of the Portfolio
will be met.

Growth and Income Portfolio

The investment objective of the Growth and Income Portfolio is long-term growth
of capital and income without excessive fluctuation in market value.

The Fund intends to keep the Portfolio's assets invested in those securities
which are selling at reasonable prices in relation to value and, in doing so, it
may have to forego some opportunities for gains when, in the Fund's judgment,
they carry excessive risk.

The Portfolio will try to anticipate major changes in the economy and select
stocks which it believes will benefit most from these changes.

The Portfolio will normally invest in common stocks (including securities
convertible into common stocks) of large, seasoned companies in sound financial
condition, which common stocks are expected to show above-average price
appreciation. Although the prices of common stocks fluctuate and their dividends
vary, historically, common stocks have appreciated in value and their dividends
have increased when the companies they represent have prospered and grown.

The Portfolio constantly seeks to balance the opportunity for profit against the
risk of loss. In the past, very few industries have continuously provided the
best investment opportunities. The Portfolio will take a flexible approach and
make adjustments to reflect changes in the opportunity for sound investments
relative to the risks assumed. Therefore, the Portfolio will sell stocks that
are judged to be overpriced and reinvest the proceeds in other securities which
are believed to offer better values.


                                      -4-
<PAGE>

The Portfolio will not purchase securities for trading purposes. To create
reserve purchasing power and also for temporary defensive purposes, the
Portfolio may invest in straight bonds and other fixed-income securities.

Other Investment Policies and Techniques

When the Fund believes that the Portfolio should assume a temporary defensive
position because of unfavorable investment conditions, the Portfolio may
temporarily hold its assets in cash and short-term money market instruments.

See "Risk Factors" below for a discussion of special diversification standards
which the Portfolio will meet.

The Fund intends to utilize from time to time one or more of the investment
techniques identified below and described in the Statement of Additional
Information. It is the Fund's current intention that no more than 5% of the
Portfolio's net assets will be at risk in the use of any one of such investment
techniques identified below. While some of these techniques involve risk when
utilized independently, the Fund intends to use them to reduce risk and
volatility in the Portfolio, although this result cannot be assured by the use
of such investment techniques.

Covered Call Options. The Fund may write call options on securities it owns. A
call option on stock gives the purchaser of the option, upon payment of a
premium to the writer of the option, the right to call upon the writer to
deliver a specified number of shares of a stock on or before a fixed date at a
predetermined price.

Rights and Warrants. The Fund may invest in rights and warrants to purchase
securities. Included within these purchases, but not exceeding 2% of the value
of the Portfolio's net assets, may be warrants which are not listed on the New
York Stock Exchange or American Stock Exchange.

Repurchase Agreements. The Fund may enter into repurchase agreements with
respect to a security. A repurchase agreement is a transaction by which the Fund
acquires a security and simultaneously commits to resell that security to the
seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon
date. The Fund requires at all times that the repurchase agreement be
collateralized by cash or U.S. Government securities having a value equal to, or
in excess of, the value of the repurchase agreement. Such agreements permit the
Fund to keep all of its assets at work while retaining flexibility in pursuit of
investments of a longer-term nature.

Other Policies of the Portfolio

It is the Fund's current intention that no more than 5% of the Portfolio's net
assets will be at risk in the use of any one of the policies identified below.


                                      -5-
<PAGE>

Closed-End Investment Companies. The Fund may invest in shares of closed-end
investment companies if bought in primary or secondary offerings with a fee or
commission no greater than the customary brokers commission. Shares of such
investment companies sometimes trade at a discount or premium in relation to
their net asset value.

Lending of Portfolio Securities. The Fund may seek to earn income by lending its
Portfolio securities if the loan is collateralized and complies with regulatory
requirements.

Emergency Borrowing. The Fund will be permitted to borrow money up to one-third
of the value of the Portfolio's total assets taken at current value but only
from banks as a temporary measure for extraordinary or emergency purposes.
Beyond 5% of the Portfolio's total assets (at current value), this borrowing may
not be used for investment leverage to purchase securities. As a matter of
operating policy, the Portfolio will not borrow more than 25% of its total
assets taken at current value.

Change in Investment Objective

The Fund will not change the investment objective of the Portfolio without
shareholder approval as described below in "Investment Restrictions." However,
the Fund's policies and techniques are not fundamental. Therefore, if it is
determined that an objective of the Portfolio can best be achieved by a
substantive change in such a policy or technique, the change will be made
without shareholder approval by disclosing it in the Prospectus.

Investment Restrictions

In addition to the investment objectives set forth above, certain restrictions
relating to the investment of assets of the Portfolio are set forth in the
Statement of Additional Information. These investment restrictions are also
deemed fundamental and neither such restrictions nor the investment objectives
of the Portfolio may be changed without the approval of the holders of a
majority of the outstanding shares of the Portfolio (which for this purpose and
under the 1940 Act means the lesser of (i) 67% of the shares represented at a
meeting at which more than 50% of the outstanding shares are present or
represented by proxy or (ii) more than 50% of the outstanding shares).

4. RISK FACTORS
- --------------------------------------------------------------------------------

The Fund serves as the underlying investment for Variable Contracts issued by
the Life Companies.

Section 817(h) of the Internal Revenue Code of 1986, as amended (the "Code"),
imposes certain diversification standards on the underlying assets of Variable
Contracts held in any Portfolios of the Fund. The Code provides that a Variable
Contract shall not be 


                                      -6-
<PAGE>

treated as an annuity contract or life insurance for any period (and any
subsequent period) for which the investments are not, in accordance with
regulations prescribed by the Treasury Department, adequately diversified.
Disqualification of a Variable Contract as an annuity contract or life insurance
would result in imposition of federal income tax on contract owners with respect
to earnings allocable to the Variable Contract prior to the receipt of payments
under the Variable Contract. Section 817(h)(2) of the Code is a safe harbor
provision which provides that contracts such as the Variable Contracts meet the
diversification requirements if, as of the close of each quarter, the underlying
assets meet the diversification standards for a regulated investment company and
no more than fifty-five percent (55%) of the total assets consists of cash, cash
items, U.S. Government securities and securities of other regulated investment
companies.

On March 2, 1989, the Treasury Department issued Regulations (Treas. Reg.
1.817-5), which established diversification requirements for the investment
portfolios underlying Variable Contracts. The Regulations amplify the
diversification requirements for Variable Contracts set forth in Section 817(h)
of the Code and provide an alternative to the safe harbor provision described
above. Under the Regulations, an investment portfolio will be deemed adequately
diversified if (i) no more than 55 percent of the value of the total assets of
the portfolio is represented by any one investment; (ii) no more than 70 percent
of such value is represented by any two investments; (iii) no more than 80
percent of such value is represented by any three investments; and (iv) no more
than 90 percent of such value is represented by any four investments. For
purposes of these Regulations, all securities of the same issuer are treated as
a single investment.

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

The Portfolio will be managed in such a manner as to comply with these
diversification requirements. It is possible that in order to comply with the
diversification requirements, less desirable investment decisions may be made
which would affect the investment performance of the Portfolio.

The prices of long-term securities are more volatile than those of short-term
debt securities. When interest rates go up or down, the market value of such
long-term debt securities tends to go down or up, respectively, to a greater
extent than in the case of short-term debt securities.

5. PORTFOLIO TURNOVER RATES
- --------------------------------------------------------------------------------

For the years ended December 31, 1996 and 1997, the portfolio turnover rates of
the Portfolio were 48.93% and 43.09%, respectively. Higher portfolio turnover
rates may 


                                      -7-
<PAGE>

involve correspondingly higher brokerage costs, which would have to be borne
directly by the Fund and ultimately by its shareholders.

6. MANAGEMENT
- --------------------------------------------------------------------------------

The Fund is managed by its officers on a day-to-day basis under the overall
direction of its Board of Directors. The Fund employs Lord Abbett as investment
manager for the Portfolio pursuant to a Management Agreement. Lord Abbett has
been an investment manager for over 68 years and currently manages approximately
$27 billion in a family of mutual funds and other advisory accounts. Lord Abbett
provides the Fund with investment management services and executive and other
personnel, pays the remuneration of its officers, provides the Fund with office
space and pays for ordinary and necessary office and clerical expenses relating
to research, statistical work and supervision of the Portfolio and certain other
costs. The Fund pays all other expenses not expressly assumed by Lord Abbett,
including, without limitation, outside Directors' fees and expenses, association
membership dues, legal and auditing fees, shareholder servicing costs, expenses
relating to shareholder meetings, expenses of preparing, printing and mailing
stock certificates and shareholder reports, expenses of registering the Fund's
shares under federal and state securities laws, expenses of printing and mailing
prospectuses to existing shareholders, insurance premiums and brokerage and
other expenses relating to the execution of Portfolio transactions. Lord Abbett
provides similar services to twelve other funds having their own investment
objectives and also advises other investment clients. Lord Abbett and Cova
Financial Services Life Insurance Company provided operating funds to the Fund
through their purchase of the initial shares of the Fund.

Mr. W. Thomas Hudson, Jr. is Executive Vice President of the Fund and is
primarily responsible for the day-to-day management of the Portfolio. Mr. Hudson
has been employed by Lord Abbett since 1982.

Under the Management Agreement, the Fund is obligated to pay Lord Abbett a
monthly fee, based on average daily net assets of the Portfolio for each month,
at an annual rate of 0.50 of 1%. In addition, the Fund will pay all expenses not
expressly assumed by Lord Abbett. For the year ended December 31, 1997, the
Portfolio of the Fund paid Lord Abbett $2,019,891 in advisory fees.

7. EXPENSES OF THE FUND
- --------------------------------------------------------------------------------

Lord Abbett may waive its management fee and/or advance other expenses of the
Fund. Although each Class must bear the expenses solely attributable to it, the
Classes are expected to experience cost savings over the aggregate amount that
would be payable if each Class were a separate fund, because they have the same
Directors, accountants, attorneys and share other general and administrative
expenses. Any expenses which are not solely attributable to a specific Class are
allocated on the basis of the net assets of the 


                                      -8-
<PAGE>

respective Classes. For the year ended December 31, 1997, the expenses borne by
the Portfolio amounted to $2,084,990 or 0.52 of 1% of its average daily net
assets.

8. SHAREHOLDER RIGHTS
- --------------------------------------------------------------------------------

The Portfolio issues one class of shares and may issue additional separate
classes of shares in the future. Each share represents an equal proportionate
interest in the assets of the Portfolio with each other share in the Portfolio.
On any matter submitted to a vote of shareholders, all shares of the Fund then
issued and outstanding and entitled to vote shall be voted in the aggregate and
not by class except for matters concerning only one class. The holder of each
share of stock of the Fund will be entitled to one vote for each full share and
a fractional vote for each fractional share of stock. Shares of one class may
not bear the same economic relationship to the Fund as shares of another class.

In accordance with its view of present applicable law, the Fund views the
separate account(s) of Life Companies as shareholders of the Fund having the
right to vote Fund shares at any meeting of shareholders and will provide
pass-through voting privileges to all contract owners. Life Companies will vote
shares of the Fund held in the separate account(s) for which no timely voting
instructions from contract owners are received, as well as shares they own, in
the same proportion as those shares for which voting instructions are received.
Additional information concerning voting rights is described in the separate
account prospectuses.

The Fund's By-Laws provide that the Fund shall not hold an annual meeting of its
shareholders in any year unless one or more matters are required to be acted on
by shareholders under the 1940 Act, or unless called at the request in writing
of a majority of the Board of Directors or by shareholders holding at least
one-quarter of the shares of the Fund outstanding and entitled to vote at the
meeting. The Fund will hold a shareholder meeting to fill existing vacancies on
the Board in the event that less than a majority of Directors were elected by
the shareholders. The Directors shall also call a meeting of shareholders for
the purpose of voting upon the question of removal of any Director when
requested in writing to do so by the record holders of not less than 10 percent
of the outstanding shares. Under the By-Laws of the Fund and in accordance with
the 1940 Act, shareholder approval of the independent auditors of the Fund will
not be required except when shareholder meetings are held. The Fund has an
obligation to assist shareholder communications.

9. PURCHASE AND REDEMPTION OF SHARES
- --------------------------------------------------------------------------------

Shares are currently only sold to the separate accounts of the Life Companies at
net asset value (see below). Redemptions will be effected by the separate
accounts to meet obligations under the Variable Contracts. Contract owners do
not deal directly with the Fund with respect to acquisition or redemption of
shares.


                                      -9-
<PAGE>

In selecting broker-dealers to execute portfolio transactions for the Fund's
Portfolio, if two or more broker-dealers are considered capable of best
execution, the Fund may prefer the broker-dealer who has sold Fund shares
through the sale of such Variable Contracts.


                                      -10-
<PAGE>

10. DIVIDENDS AND DISTRIBUTIONS
- --------------------------------------------------------------------------------

All dividends and distributions are distributed to the shareholders and will be
payable in shares or cash at the election of shareholders. The Life Companies,
with respect to shares held by their separate accounts, have elected, and intend
to continue to elect, to receive dividends and distributions in shares.
Dividends and distributions are made at such frequency and in such amount as to
assure compliance with the Internal Revenue Code.

11. TAX STATUS
- --------------------------------------------------------------------------------

It is the intention of the Fund to have the Portfolio qualify, and for the
fiscal year ended December 31, 1997, it did qualify, as a "regulated investment
company" under Subchapter M of the Internal Revenue Code. The Fund distributes
all of its net income and gains to its shareholders ( including the separate
accounts). The Portfolio is treated as a separate entity for federal income tax
purposes and, therefore, the investments and results of the Portfolio are
determined separately for purposes of determining whether the Portfolio
qualifies as a "regulated investment company" and for purposes of determining
net ordinary income (or loss) and net realized capital gains (or losses).

12. NET ASSET VALUE
- --------------------------------------------------------------------------------

Portfolio shares are sold and redeemed at a price equal to the share's net asset
value. Net asset value per share is determined as of the close of the New York
Stock Exchange (normally 4:00 P.M. Eastern Standard Time) on each day that the
New York Stock Exchange is open for trading by dividing the net assets of each
class by the number of shares outstanding for that class at the time of
calculation. The daily net asset value per share is also determined once daily
on each day (other than a day during which no such shares were tendered for
redemption and no order to purchase or sell such shares was received by the
Fund) in which there is a sufficient degree of trading in the Portfolio's
securities that the current net asset value of the Portfolio's shares might be
materially affected by changes in the value of the securities.

Total assets are determined by adding the total current value of the Portfolio's
securities, cash, receivables and other assets and subtracting liabilities.
Portfolio shares are sold and redeemed at the net asset value next determined
after receipt of the sales order or request for redemption.

Securities that are listed on a securities exchange are valued at their closing
sales price on the day of the valuation. Price valuations for listed securities
are based on market quotations where the security is primarily traded or, if not
available, are valued at the mean of the bid and asked prices on any valuation
date. Unlisted securities in a Portfolio are primarily valued based on their
latest quoted bid price or, if not available, are valued by a method determined
by the Directors to accurately reflect fair value. Money market 


                                      -11-
<PAGE>

instruments maturing in 60 days or less are valued on the basis of amortized
cost, which means that they are valued at their acquisition cost to reflect a
constant amortization rate to maturity of any premium or discount, rather than
at current market value.

13. PERFORMANCE
- --------------------------------------------------------------------------------

From time to time, advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Total
return information will include the Portfolio's average annual compounded rate
of return for a given period, based upon the value of the shares acquired
through a hypothetical $1000 investment at the beginning of the specified period
and the net asset or redemption value of such shares at the end of the period,
assuming reinvestment of all dividends and distributions at net asset value. In
lieu of or in addition to total return calculations, such information may
include performance rankings and similar information from independent
organizations such as Lipper Analytical Services, Inc., Business Week, Forbes or
other industry publications.

Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share can be expected to fluctuate over time. Further information
about the Fund's performance is contained in the Annual Report to shareholders
which may be obtained, without charge, by calling 800-831-LIFE with respect to
Variable Contracts of Cova ; 800-342-6307 with respect to Variable Contracts of

                       Investment Objectives and Policies

The Fund's investment objectives and policies are described in the Prospectus
under "Investment Objectives and Policies." In addition to those investment
objectives, the Growth and Income Portfolio (the "Portfolio") is subject to the
following investment restrictions which cannot be changed without approval of a
majority of the outstanding shares of the Portfolio. The Portfolio may not: (1)
sell short securities or buy securities or evidences of interests therein on
margin, although it may obtain short-term credit necessary for the clearance of
purchases of securities; (2) buy or sell put or call options, although it may
buy, hold or sell rights or warrants, write covered call options and enter into
closing purchase transactions as discussed below; (3) borrow money which is in
excess of one-third of the value of its total assets taken at market value
(including the amount borrowed) and then only from banks as a temporary measure
for extraordinary or emergency purposes (borrowings beyond 5% of such total
assets may not be used for investment leverage to purchase securities but solely
to meet redemption requests where the liquidation of the Portfolio's investment
is deemed to be inconvenient or disadvantageous); (4) invest in securities or
other assets not readily marketable at the time of purchase or subject to legal
or contractual restrictions on resale except as described under "Restricted or
Not Readily Marketable Securities for the Fund's Portfolio" below; (5) act as
underwriter of securities issued by others, unless it is deemed to be one in
selling a portfolio security requiring registration under the Securities Act of
1933, such as those described under "Restricted or Not Readily Marketable
Securities for the Fund's Portfolio" below; (6) lend money or securities to any
person except that it may enter into short-term repurchase agreements with
sellers of securities it has purchased, and it may lend its portfolio securities
to registered broker-dealers where the loan is 100% secured by cash or its
equivalent as long as it complies with regulatory requirements and the Fund
deems such loans not to expose the Portfolio to significant risk (investment in
repurchase agreements exceeding 7 days and in other illiquid investments is
limited to a maximum of 5% of a Portfolio's assets); (7) pledge, mortgage or
hypothecate its assets; however, this provision does not apply to permitted
borrowing mentioned above or to the grant of escrow receipts or the entry into
other similar escrow arrangements arising out of the writing of covered call
options; (8) buy or sell real estate including limited partnership interests
therein (except securities of companies, such as real estate investment trusts,
that deal in real estate or interests therein), or oil, gas or other mineral
leases, commodities or commodity contracts in the ordinary course of its
business, except such interests and other property acquired as a result of
owning 


                                      -14-
<PAGE>

other securities, though securities will not be purchased in order to acquire
any of these interests; (9) invest more than 5% of its gross assets, taken at
market value at the time of investment, in companies (including their
predecessors) with less than three years' continuous operation; (10) buy
securities if the purchase would then cause a Portfolio to have more than (i) 5%
of its gross assets, at market value at the time of purchase, invested in
securities of any one issuer, except securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, or (ii) 25% of its gross assets,
at market value at the time of purchase, invested in securities issued or
guaranteed by a foreign government, its agencies or instrumentalities; (11) buy
voting securities if the purchase would then cause a Portfolio to own more than
10% of the outstanding voting stock of any one issuer; (12) own securities in a
company when any of its officers, directors or security holders is an officer or
director of the Fund or an officer, director or partner of the Investment
Manager or sub-adviser, if after the purchase any of such persons owns
beneficially more than 1/2 of 1% of such securities and such persons together
own more than 5% of such securities; (13) concentrate its investments in any
particular industry, but if deemed appropriate for attainment of its investment
objective, up to 25% of its gross assets (at market value at the time of
investment) may be invested in any one industry classification used for
investment purposes; or (14) buy securities from or sell them to the Fund's
officers, directors, or employees, or to the Investment Manager or sub-adviser
or to their partners, directors and employees.

Changes in Fund Objectives, Restrictions, Policies and Strategies

The Fund's investment objectives described in the Prospectus and the Fund's
investment restrictions described above in this Statement of Additional
Information, both under the same heading "Investment Objectives and Policies,"
can be changed only with the approval of a majority of the outstanding shares of
the affected Portfolio. All of the Fund's policies and techniques, including
those described below, can be changed without such approval.

Other Investments. Described below are other Fund policies and techniques
applicable to one or all of the Portfolios as indicated.

Investment Techniques for the Fund's Portfolio

The Fund intends to utilize from time to time one or more of the investment
techniques described below, including covered call options, rights and warrants
and repurchase agreements. It is the Fund's current intention that no more than
5% of the Portfolio's net assets will be at risk in the use of any one of such
investment techniques. While some of these techniques involve risk when utilized
independently, the Fund intends to use them to reduce risk and volatility in its
Portfolio.


                                      -15-
<PAGE>

Covered Call Options. The Fund may write call options on securities it owns. A
call option on stock gives the purchaser of the option, upon payment of a
premium to the writer of the option, the right to call upon the writer to
deliver a specified number of shares of a stock on or before a fixed date at a
predetermined price.

The writing of call options will, therefore, involve a potential loss of
opportunity to sell securities at higher prices. The writer of a fully
collateralized call option assumes the full downside risk of the securities
subject to such option. In addition, in exchange for the premium received, the
writer of the call gives up the gain possibility of the stock appreciating
beyond the call price. While an option that has been written is in force, the
maximum profit that may be derived from the optioned stock is the sum of the
premium (less brokerage commissions and fees) plus the difference between the
strike price of the call and the market price of the underlying security.

The Fund's custodian will segregate cash, liquid high grade debt securities or
other permitted securities in an amount not less than the value of the Fund's
assets committed to written covered call options. If the value of the securities
segregated declines, additional cash or permitted securities will be added on a
daily basis (i.e., marked to market) so that the segregated amount will not be
less than the amount of the Fund's commitments with respect to such written
options.

Rights and Warrants. The Fund may invest in rights and warrants to purchase
securities. Included within that amount, but not to exceed 2% of the value of
the Portfolio's net assets, may be warrants which are not listed on the New York
Stock Exchange or American Stock Exchange.

Rights represent a privilege offered to holders of record of issued securities
to subscribe (usually on a pro rata basis) for additional securities of the same
class, of a different class, or of a different issuer, as the case may be.
Warrants represent the privilege to purchase securities at a stipulated price
and are usually valid for several years. Rights and warrants generally do not
entitle a holder to dividends or voting rights with respect to the underlying
securities nor do they represent any rights in the assets of the issuing
company.

Also, the value of a right or warrant may not necessarily change with the value
of the underlying securities, and rights and warrants cease to have value if
they are not exercised prior to their expiration date.

Repurchase Agreements. The Fund may enter into repurchase agreements with
respect to a security. A repurchase agreement is a transaction by which the Fund
acquires a security and simultaneously commits to resell that security to the
seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon
date. The resale price reflects the purchase price plus an agreed-upon market
rate of interest which is unrelated to the coupon rate or date of maturity of
the 


                                      -16-
<PAGE>

purchased security. In this type of transaction, the securities purchased by the
Fund have a total value in excess of the value of the repurchase agreement. The
Fund requires at all times that the repurchase agreement be collateralized by
cash or U.S. government securities having a value equal to, or in excess of, the
value of the repurchase agreement. Such agreements permit the Fund to keep all
of its assets at work while retaining flexibility in pursuit of investments of a
longer-term nature.

The use of repurchase agreements involves certain risks. For example, if the
seller of the agreement defaults on its obligation to repurchase the underlying
securities at a time when the value of these securities has declined, the Fund
may incur a loss upon disposition of them. If the seller of the agreement
becomes insolvent and subject to liquidation or reorganization under the
Bankruptcy Code or other laws, a bankruptcy court may determine that the
underlying securities are collateral not within the control of the Fund and
therefore subject to sale by the trustee in bankruptcy. Even though the
repurchase agreements may have maturities of seven days or less, they may lack
liquidity, especially if the issuer encounters financial difficulties. While the
Fund acknowledges these risks, it is expected that they can be controlled
through stringent selection criteria and careful monitoring procedures. The Fund
intends to limit repurchase agreements to transactions with dealers and
financial institutions believed by the Fund to present minimal credit risks. The
Fund will monitor creditworthiness of the repurchase agreement sellers on an
ongoing basis.

Restricted or Not Readily Marketable Securities for the Fund's Portfolio

Although the Fund has no current intention of investing in such securities in
the foreseeable future, no more than 5% of the value of the Portfolio may be
invested in securities with legal or contractual restrictions on resale
("restricted securities") (including securities qualifying for resale under SEC
Rule 144A that are determined by the Board, or by Lord Abbett pursuant to the
Board's delegation, to be liquid securities, restricted securities, repurchase
agreements with maturities of more than seven days and over-the-counter
options), other than repurchase agreements and those restricted securities which
have a liquid market among certain institutions, including the Fund, and in
securities which are not readily marketable.

Lending of Securities by the Fund's Portfolio

Although the Fund has no current intention of doing so in the foreseeable
future, the Fund may seek to earn income by lending portfolio securities. Under
present regulatory policies, such loans may be made to member firms of the New
York Stock Exchange and are required to be secured continuously by collateral
consisting of cash, cash equivalents, or United States Treasury bills maintained
in an amount at least equal to the market value of the securities loaned. The


                                      -17-
<PAGE>

Fund will have the right to call a loan and obtain the securities loaned at any
time on five days' notice. During the existence of a loan the Fund will receive
the income earned on investment of collateral. The aggregate value of the
securities loaned will not exceed 15% of the value of the Portfolio's total
assets.

Portfolio Turnover Rates

During the fiscal year ended December 31, 1997, the portfolio turnover rate of
the Portfolio was 43.09% compared to 48.93% for the prior fiscal year.

(1)   Outside directors' fees, including attendance fees for board and committee
      meetings, are allocated among all Lord Abbett-sponsored funds based on the
      net assets of each fund. A portion of the fees payable by the Fund to its
      outside directors is being deferred under a plan that deems the deferred
      amounts to be invested in shares of the Fund for later distribution to the
      directors.

(2)   The amounts in Column 3 were accrued by the Lord Abbett-Sponsored Funds
      for the 12 months ended December 31, 1997 with respect to the equity based
      plans established for independent directors in 1996. This plan supercedes
      a previously approved retirement plan for all future directors. Current
      directors had the option to convert their accrued benefits under the
      retirement plan. All of the outside directors except one made such an
      election. Each plan also provides for a pre-retirement death benefit and
      actuarially reduced joint-and-survivor spousal benefits.

(3)   This column shows aggregate compensation, including directors fees and
      attendance fees for board and committee meetings, of a nature referred to
      in footnote one, accrued by the Lord Abbett-sponsored funds during the
      year ended December 31, 1997. The amounts of the aggregate compensation
      payable by the Fund as of December 31, 1997 deemed invested in Fund
      shares, including dividends reinvested and changes in net asset value
      applicable to such deemed investments, were: Mr. Bigelow, $ 3,135; Mr.
      Dixon, $1,078; Mr. Jansing, $4,041; Mr. MacDonald, $1,040; Mr. Millican,
      $4,076 and Mr. Neff, $ 4,041. If the amounts deemed invested in Fund
      shares were added to each director's actual holdings of Fund shares as of
      December 31, 1997, each would own, the following: Mr. Bigelow, 60 shares;
      Mr. Dixon, 59 shares; Mr. Jansing, 59 shares; Mr. McDonald, 62 shares; Mr.
      Millican, 59 shares; and Mr. Neff, 60 shares.

(4)   Mr. Jansing chose to continue to receive benefits under the retirement
      plan, which provides that outside directors (Trustees) may receive annual
      retirement benefits for life equal to their final annual retainer
      following retirement at or after age 72 with at least ten years of
      service. Thus, if Mr. Jansing were to retire and the annual retainer
      payable by the funds were the same as it is today, he would receive annual
      retirement benefits of $50,000.

The services to be provided by Lord Abbett are described under "Management" in
the Prospectus. Under the Management Agreement, the Fund on behalf of the
Portfolio is obligated to pay Lord Abbett a monthly fee, based on the average
daily net assets of the Portfolio for each month, at the annual rate of 0.50 of
1%. For the fiscal years ended December 31, 1995, 1996 and 1997 Lord Abbett
received $704,093, $1,234,273 and $2,019,891 in advisory fees, respectively.

The Fund pays all expenses not expressly assumed by Lord Abbett, including,
without limitation, outside directors' fees and expenses, association membership
dues, legal and auditing fees, taxes, transfer and dividend disbursing agent
fees, shareholder servicing costs, expenses relating to shareholder meetings,
expenses of preparing, printing and mailing stock certificates and shareholder
reports, expenses of registering the Fund's shares under federal and state
securities laws, expenses of printing and mailing prospectuses to existing

held by BNY or its foreign branches to be held by certain qualified foreign
banks and depositories.

                             Portfolio Transactions

Our policy is to obtain best execution on all our portfolio transactions, which
means that we seek to have purchases and sales of portfolio securities executed
at the most favorable prices, considering all costs of the transaction including
brokerage commissions and dealer markups and markdowns and taking into account
the full range and quality of the brokers' services. Consistent with obtaining
best execution, we generally pay, as described below, a higher commission than
some brokers might charge on the same transactions. Our policy with respect to
best execution governs the selection of brokers or dealers and the market in
which the transaction is executed. To the extent permitted by law, we may, if
considered advantageous, make a purchase from or sale to another Lord
Abbett-sponsored fund without the intervention of any broker-dealer.

Broker-dealers are selected on the basis of their professional capability and
the value and quality of their brokerage and research services. Normally, the
selection is made by traders who are officers of the Fund and also are employees
of Lord Abbett. These traders do the trading as well for other accounts --
investment companies (of which they are also officers) and other investment
clients -- managed by Lord Abbett. They are responsible for obtaining best
execution.

We pay a commission rate that we believe is appropriate to give maximum
assurance that our brokers will provide us, on a continuing basis, the highest
level of brokerage services available. While we do not always seek the lowest
possible commissions on particular trades, we believe that our commission rates
are in line with the rates that many other institutions pay. Our traders are
authorized to pay brokerage commissions in excess of those that other brokers
might accept on the same transactions in recognition of the value of the
services performed by the executing brokers, viewed in terms of either the
particular transaction or the overall responsibilities of Lord Abbett with
respect to us and the other accounts they manage. Such services include showing
us trading opportunities including blocks, a willingness and ability to take
positions in securities, knowledge of a particular security or market proven
ability to handle a particular type of trade, confidential treatment, promptness
and reliability.

Some of these brokers also provide research services at least some of which are
useful to Lord Abbett in their overall responsibilities with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,


                                      -23-
<PAGE>

portfolio strategy and the performance of accounts and trading equipment and
computer software packages, acquired from third-party suppliers, that enable
Lord Abbett to access various information bases. Such services may be used by
Lord Abbett in servicing all their accounts, and not all of such services will
necessarily be used by Lord Abbett in connection with their management of the
Fund; conversely, such services furnished in connection with brokerage on other
accounts managed by Lord Abbett may be used in connection with their management
of the Fund, and not all of such services will necessarily be used by Lord
Abbett in connection with their advisory services to such other accounts. We
have been advised by Lord Abbett that research services received form brokers
cannot be allocated to any particular account, are not a substitute for Lord
Abbett's services but are supplemental to their own research effort and when
utilized, are subject to internal analysis before being incorporated by Lord
Abbett into their investment process. As a practical matter, it would not be
possible for Lord Abbett to generate all of the information presently provided
by brokers. While receipt of research services from brokerage firms has not
reduced Lord Abbett's normal research activities, the expenses of Lord Abbett
could be materially increased if it attempted to generate such additional
information through its own staff and purchased such equipment and software
packages directly from the suppliers.

No commitments are made regarding the allocation of brokerage business to or
among brokers, and trades are executed only when they are dictated by investment
decisions of the Fund to purchase or sell portfolio securities.

If two or more broker-dealers are considered capable of offering the equivalent
likelihood of best execution, the broker-dealer who has sold our shares and/or
shares of other Lord Abbett-sponsored funds may be preferred.

If other clients of Lord Abbett buy or sell the same security at the same time
as we do, transactions will, to the extent practicable, be allocated among all
participating accounts in proportion to the amount of each order and will be
executed daily until filled so that each account shares the average price and
commission cost of each day. Other clients who direct that their brokerage
business be placed with specific brokers or who invest through wrap accounts
introduced to Lord Abbett by certain brokers may not participate with us in the
buying and selling of the same securities as described above. If these clients
wish to buy or sell the same security as we do, they may have their transactions
executed at times different from our transactions and thus may not receive the
same price or incur the same commission cost as we do.

We will not seek "reciprocal" dealer business (for the purpose of applying
commissions in whole or in part for our benefit or otherwise) from dealers as
consideration for the direction to them of portfolio business.

During the fiscal years ended December 31, 1997, 1996 and 1995, the total dollar
amounts of brokerage commissions paid by the Fund were $631,256, $389,776 and
$409,371, respectively.

                                       6.
                         Net Asset Value of Fund Shares

Information concerning how we value our shares for the purchase and redemption
of our shares is contained in the Prospectus under "Purchase and Redemption of
Shares," respectively.

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock Exchange ("NYSE") (normally at 4:00 P.M. Eastern Standard
Time) on each day that the NYSE is open for trading by dividing our total net
assets by the number of shares outstanding at the time of calculation. The NYSE
is closed on Saturdays and Sundays and the following holidays -- New Year's Day,
Martin Luther King, Jr.'s Birthday (observed), Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.

Valuation of Securities Held in the Portfolio

The Fund values its portfolio securities at market value as of the close of the
NYSE. Market value will be determined as follows: securities listed or admitted
to trading privileges on the New York or American Stock Exchange or on the
NASDAQ National Market System are valued at the last sales price, or, if there
is no sale on that day, at the mean between the last bid and asked prices, or,
in the case of bonds, in the over-the-counter market if, in the judgment of the
Fund's officers, that market more accurately reflects the market value of the
bonds. Over-the-counter securities not traded on the NASDAQ National Market
System are valued at the mean between the last bid and asked prices. Securities
for which market quotations are not available are valued at fair market value
under procedures approved by the Board of Directors.

                                       7.
                           Dividends and Distributions

It is the Fund's intention to distribute substantially all the net investment
income, if any, of the Portfolio. For dividend purposes, net investment income
of the Portfolio will consist of dividends and/or interest earned by the
Portfolio less the expenses of such Portfolio.

All net realized capital gains of the Fund, if any, are declared and distributed
annually.

                            Distribution Arrangements

General

Lord Abbett Distributor LLC ("Lord Abbett Distributor") serves as the
distributor in connection with the offering of the Fund's shares. In connection
with the sale of its shares, the Fund has authorized Lord Abbett Distributor to
provide only such information and to make only such statements and
representations which are not materially misleading or which are contained in
the Fund's then current Prospectus or Statement of Additional Information or
shareholder reports in such financial and other statements which are furnished
to Lord Abbett by the Fund.

The Fund and Lord Abbett Distributor are parties to a Distribution Agreement
that continues in force until December, 1998. The Distribution Agreement may be
terminated by either party and will automatically terminate in the event of its
assignment. The Distribution Agreement may be renewed annually if specifically
approved by the Board of Directors or by vote of a majority of the outstanding
voting securities of the Fund provided that any such renewal shall be approved
by the vote of a majority of the Directors who are not parties to the
Distribution Agreement and are not "interested persons" of the Fund and have no
direct or indirect financial interest in the operation of the Distribution
Agreement.

                                       9.
                                      Taxes

The Fund intends to qualify as a regulated investment company under Subchapter M
of the Internal Revenue Code of 1986, as amended. Under such provisions, the
Fund will not be subject to Federal income tax on that part of its net ordinary
income and net realized capital gains which it distributes to shareholders. The
Portfolio will be treated as a separate entity for Federal income tax purposes
and, therefore, the investments and results of the Portfolio are determined
separately for purposes of determining whether the Fund qualifies as a regulated
investment company and for purposes of determining the Fund's net ordinary
income (or loss) and net realized capital gains (or losses). To qualify for
treatment as a regulated investment company, the Fund must, among other things,
derive in each taxable year at least 90% of its gross income from dividends,
interest and gains from the sale or other disposition of securities and certain
other related income and derive less than 30% of its gross income in each
taxable year from the gains (without deduction for losses) from the sale or
other disposition of securities (including, in certain circumstances, gains from
options, futures, forward contracts and foreign currencies) held for less than
three months.

                         Calculation of Performance Data

The Portfolio's average annual compounded rate of return is determined by
reference to a hypothetical $1,000 investment that includes capital appreciation
and depreciation for the stated period, according to the following formula:

                           P(1+T)(n) = ERV

where

P   =             a hypothetical initial payment of $1000
T   =             average annual total return
n   =             number of years
ERV   =           ending redeemable value of the hypothetical $1000 purchase
                  at the end of the period.

Aggregate total return is calculated in a similar manner, except that the
results are not annualized. Each calculation assumes that all dividends and
distributions are reinvested at net asset value on the reinvestment dates during
the period.

Using this method to compute average annual compounded rates of total return for
the Portfolio's last one, five and the life of the fund periods ending on
December 31, 1997 were: 24.34%, 17.87% and 16.56% respectively.

                                       11.
                              Financial Statements

The financial statements for the fiscal year ended December 31, 1997 and the
report of Deloitte & Touche LLP, independent auditors, on such financial
statements contained in the 1997 Annual Report to Shareholders of Lord Abbett
Series Fund, Inc. are incorporated herein by reference to such financial
statements and report in reliance upon the authority of Deloitte & Touche LLP as

            F. To do any and all things herein set forth, and in addition such
other acts and things as are necessary or convenient to the attainment of the
purposes of this Corporation, or any of them, to the same extent as natural
persons lawfully might or could do in any part of the world, and to engage in
any lawful act or activity for which corporations may be organized under the
laws of the State of Maryland.

            The foregoing objects and purposes shall, except as otherwise
expressly provided, be in no way limited or restricted by reference to, or
inference from the terms of any other clause of this or any other Article of
these Articles of Incorporation, and shall each be regarded as independent, and
construed as powers as well as objects and purposes, and the enumeration of
specific purposes, objects and powers shall not be


                                       2

construed to limit or restrict in any manner the meaning of general terms or the
general powers of the Corporation now or hereafter conferred by the laws of the
State of Maryland, nor shall the expression of one thing be deemed to exclude
another, though it be of like nature, not expressed; provided, however, that the
Corporation shall not have power to carry on within the State of Maryland any
business whatsoever the carrying on of which would preclude it from being
classified as an ordinary business corporation under the laws of said State; nor
shall any of the foregoing statements of its objects, purposes and powers be
deemed to permit the Corporation to carry on any business, or exercise any
powers, in any state, territory, district or county except to the extent that
the same may lawfully be carried on or exercised under the laws thereof.

                                    ARTICLE V

            SECTION 1. The total number of shares which the Corporation has
authority to issue is 1,000,000,000 shares of capital stock of the par value of
$.001 each (the "Shares"), having an aggregate par value of $1,000,000. The
Shares shall initially constitute three classes designated initially as the
"Growth & Income Class", consisting of 50,000,000 Shares, the "Growth Class",
consisting of 50,000,000 Shares and the "Global Equity Class", consisting of
50,000,000 Shares. The Board of Directors shall have the power and authority to
further classify or reclassify any unissued Shares from time to time, including
the power and authority to allocate classes of Shares (including classes of
unissued Shares with classes of Issued Shares) to series of Shares, by setting
or changing the preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends, qualifications, or terms or
conditions of redemption of such classes and series of Shares. For the purpose
of these Articles of Incorporation, the term "Class" shall mean such an initial
separate and distinct class of Shares and any further separate and distinct
class of Shares from time to time created by the Board of Directors and the term
"Series" shall mean a series of Shares to which any two or more Classes are
allocated by the Board of Directors. The Board of Directors shall also have the
power and authority to redesignate any class of series of issued Shares by
setting forth such redesignation in Articles Supplementary filed with the
Maryland State Department of Assessments and Taxation.

      [On November 6, 1996, the Articles of Incorporation of the Corporation
were further supplemented by the filing of Articles Supplementary with the State
Department of Assessments and Taxation of Maryland which specified the legal
name for the existing Growth and Income Class of the Corporation as the
"Variable Contract Class."


                                       3

      On November 6, 1996, the Articles of Incorporation of the Corporation were
further supplemented by the filing of Articles Supplementary with the State
Department of Assessments and Taxation of Maryland which, pursuant to the power
and authority of the Board of Directors of the Corporation to classify and
reclassify unissued Shares of stock of the Corporation, including the power and
authority to allocate Classes of Shares to Series of Shares, classified the
capital stock of the Corporation by (a) classifying from previously unclassified
Shares, 50,000,000 authorized but unissued Shares as the "Pension Class," and
(b) allocating the Variable Contact Class and the Pension Class to a Series of
Shares designated as the "Growth and Income Portfolio" (the "Portfolio"). Such
Articles Supplementary further provided that all Shares of a Class or of a
Series shall represent the same interest in the Corporation and have the same
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications, and terms and conditions of
redemption as the other Shares of that Class or Series, except to the extent
that the Board of Directors provides for differing preferences, conversion or
other rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption of Shares of such Classes
or such Series as determined pursuant to the Articles, or as otherwise
determined pursuant to those Articles Supplementary or additional Articles
Supplementary filed for record with the State Department of Assessments and
Taxation of Maryland, or by the Board of Directors in accordance with law.

      Such Articles Supplementary further provided that subject to the power of
the Board of Directors to classify and reclassify unissued shares, all Shares of
the Pension Class and the Variable Contract Class of the Portfolio shall be
invested in the investment portfolio of the Corporation, and shall have the same
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications, and terms and conditions of
redemption set forth in Article V of the Articles of Incorporation of the
Corporation and shall be subject to all other provisions of the Articles of
Incorporation relating to stock of the Corporation generally and to the
provisions of those Articles Supplementary.

      Such Articles Supplementary further provided that liabilities and expenses
relating solely to a particular Class of the Portfolio (including, without
limitation, distribution expenses under a plan in effect adopted for such Class
pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended (the
"Act"), and administrative expenses under an administration or service
agreement, plan or other arrangement, however designated, which may be adopted
for such Class) shall be allocated to and borne by such Class of the Portfolio
to the extent determined by the Board of Directors, and shall be 


                                       4
<PAGE>

appropriately reflected (in the manner determined by the Board of Directors) in
the net asset value, dividends and distributions and liquidation rights of the
Shares of such Class.

      Such Articles Supplementary further provided that dividends paid by the
Corporation on each Class of Shares of the Portfolio, to the extent any
dividends are paid, will be calculated in the same manner, will be paid at the
same time, and will be in the same amount, except that (a) any expenses
allocated to a Class of the Portfolio, in the manner set forth under those
Articles Supplementary, shall be borne exclusively by that Class and (b) income,
realized and unrealized capital gains and losses and expense not allocated to a
Class of the Portfolio shall be allocated to each Class on the basis of the net
asset value of that Class in relation to the net asset value of the Portfolio.

      Such Articles Supplementary further provided that the net asset value of
each Share of a Class of the Portfolio shall be determined in accordance with
the Articles with appropriate adjustments to reflect the allocations of
expenses, income, and realized and unrealized capital gains and losses of the
Portfolio between its Classes as provided above. The assets belonging to each
Class shall be combined and the assets belonging to such Class shall be an
undivided interest in such combined assets, the percentage of which shall be
determined from time to time on the basis of the net asset value of that Class,
in relation to the net asset value of the Portfolio.]

            SECTION 2. A description of the relative preferences, conversion and
other rights, voting powers, restrictions, limitations as to dividends,
qualifications and terms and conditions of redemption of all Classes of Shares
is as follows, unless otherwise set forth in Articles Supplementary filed with
the Maryland State Department of Assessments and Taxation describing any further
Class or Classes or any Series from time to time created by the Board of
Directors:

            (a) Assets Belonging to Class. All consideration received by the
      Corporation for the issuance or sale of Shares of a particular Class,
      together with all assets in which consideration is invested or reinvested,
      all income, earnings, profits and proceeds thereof, including any proceeds
      derived from the sale, exchange or liquidation of such assets, and any
      funds or payments derived from any reinvestment of such proceeds in
      whatever form the same may be, shall belong to that Class for all
      purposes, subject only to the rights of creditors, and shall be so
      recorded upon the books of account of the Corporation. Such consideration,
      assets, income, earnings, profits and proceeds, including any proceeds
      derived from the sale, exchange or liquidation of such assets, and any
      funds or payments derived from any reinvestment of such proceeds, in
      whatever form the same may 


                                       5
<PAGE>

      be, together with any unallocated items (as hereinafter defined) relating
      to that Class as provided in the following sentence, are herein referred
      to as "assets belonging to" that Class. In the event that there are any
      assets, income, earnings, profits or proceeds thereof, funds or payments
      that are not readily identifiable as belonging to any particular Class
      (collectively "Unallocated Items"), the Board of Directors shall allocate
      such Unallocated Items to and among any one or more of the Classes created
      from time to time in such manner and on such basis as it, in its sole
      discretion, deems fair and equitable; and any Unallocated Items so
      allocated to a particular Class shall belong to that Class. Each such
      allocation by the Board of Directors shall be conclusive and binding upon
      stockholders of all Classes for all purposes. If two or more Classes
      comprise a Series, the assets belonging to each such Class shall be
      combined and the assets belonging to each such Class shall be combined and
      the assets belonging to such a Class shall be an undivided interest in
      such combined assets, the percentage of which shall be determined in the
      manner set forth in the Articles Supplementary filed with the Maryland
      State Department of Assessments and Taxation describing such Series.

            (b) Liabilities Belonging to Class. The assets belonging to each
      particular Class shall be charged with the liabilities of the Corporation
      in respect of that Class and with all expenses, costs, charges and
      reserves attributable to that Class, and shall be so recorded upon the
      books of account of the Corporation. Such liabilities, expenses, costs,
      charges and reserves, together with any unallocated items (as hereinafter
      defined) relating to that Class as provided in the following sentence, so
      charged to that Class, are herein referred to as "liabilities belonging
      to" that Class. In the event there are any unallocated liabilities,
      expenses, costs, charges or reserves of the Corporation which are not
      readily identifiable as belonging to any particular Class (collectively
      "Unallocated Items"), the Board of Directors shall allocate and charge
      such Unallocated Items to and among any one or more of the Classes created
      from time to time in such manner and on such basis as the Board of
      Directors in its sole discretion deems fair and equitable; and any
      Unallocated Items so allocated and charged to a particular Class shall
      belong to that Class. Each such allocation by the Board of Directors shall
      be conclusive and binding upon the stockholders of all Classes for all
      purposes.

            (c) Dividends. Dividends and distributions on Shares of a particular
      Class may be paid to the holders of Shares of that Class at such times, in
      such manner and from such of the income and capital gains, accrued or
      realized, from the assets belonging to that Class, after providing for
      actual and accrued liabilities belonging to that Class, as the Board of
      Directors may determine.


                                       6
<PAGE>

            (d) Liquidation. In the event of the liquidation or dissolution of
      the Corporation the stockholders of each Class that has been created shall
      be entitled to receive, as a Class, when and as declared by the Board of
      Directors, the excess of the assets belonging to that Class over the
      liabilities belonging to that Class. The assets so distributable to the
      stockholders of any particular class shall be distributed among such
      stockholders in proportion to the number of shares of the Class held by
      them and recorded on the books of the Corporation.

            (e) Voting. On each matter submitted to vote of the stockholders,
      each holder of a Share shall be entitled to one vote for each such Share
      standing in his name on the books of the Corporation irrespective of the
      Class thereof and all Shares of all Classes shall vote as a single class
      ("Single Class Voting"); provided, however, that (i) as to any matter with
      respect to which a separate vote of any Class or Series is required by the
      Investment Company Act of 1940 or would be required under the Maryland
      General Corporation Law, such requirements as to a separate vote by that
      Class or Series shall apply in lieu of Single Class Voting as described
      above; (ii) in the event that the separate vote requirements referred to
      in (i) above apply with respect to one or more Classes or Series or
      classes, then, subject to (iii) below, the Shares of all other Classes
      shall vote as a single class; and (iii) as to any matter which does not
      affect the interest of a particular Class or Series, only the holders of
      Shares of the one or more affected Classes or Series shall be entitled to
      vote.

            (f) Equality. All Shares of each particular Class shall represent an
      equal proportionate interest in the assets belonging to that Class
      (subject to the liabilities belonging to that Class), and each Share of
      any particular Class shall be equal to each other Share of that Class, but
      the provisions of this sentence shall not restrict any distinctions that
      may exist with respect to stockholder elections to receive dividends or
      distributions in cash or Shares or that may otherwise exist with respect
      to dividends and distributions on Shares of the same Class.

            SECTION 3. The Shares of the Corporation, of any Class, shall be
subject to the following provisions:

            (a) All Shares now or hereafter authorized, of any Class, shall be
      subject to redemption and be redeemable at the option of the stockholder,
      in the sense used in the general laws of the State of Maryland authorizing
      the formation of corporations. Each holder of the Shares, upon request to
      the Corporation accompanied by surrender (to the Corporation, or an agent
      designated by it) of the 


                                       7
<PAGE>

      appropriate stock certificate or certificates, if any, in proper form for
      transfer, and such other instruments as the Board of Directors may
      require, shall be entitled to require the Corporation to redeem all or any
      part of the Shares outstanding in the name of such holder on the books of
      the Corporation, at a redemption price for Shares of that Class equal to
      the net asset value of such Shares of that Class determined as hereinafter
      set forth, less a charge, not to exceed one percent (1%) of such net asset
      value, if and as fixed by resolution of the Board of Directors of the
      Corporation from time to time.

            (b) Notwithstanding the foregoing, the Board of Directors of the
      Corporation may suspend the right of the holders of the Shares of any
      Class to require the Corporation to redeem Shares or may suspend any
      voluntary purchase of such Shares:

                  (i) for any period (A) during which the New York Stock
            Exchange is closed other than the customary weekend and holiday
            closing, or (B) during which trading on the New York Stock Exchange
            is restricted;

                  (ii) for any period during which an emergency, as defined by
            the rules of the Securities and Exchange Commission or any successor
            thereto, exists as a result of which (A) disposal by the Corporation
            of securities owned by it is not reasonably practicable, or (B) it
            is not reasonably practicable for the Corporation fairly to
            determine the value of its net assets; or

                  (iii) for such other periods as the Securities and Exchange
            Commission or any successor thereto may by order permit for the
            protection of security holders of the Corporation.

            (c) the Corporation, pursuant to a resolution of the Board of
      Directors and without the vote or consent of stockholders of the
      Corporation, shall have the right to redeem at net asset value all Shares,
      of any Class, in any stockholder account in which there are less than 25
      Shares or such lesser number of Shares as shall be specified in such
      resolution. Such resolution shall set forth that redemption of Shares in
      such accounts has been determined to be necessary to reduce
      disproportionately burdensome expenses in servicing stockholder accounts,
      or to be otherwise in the economic best interest of the Corporation. Such
      resolution shall provide that prior notice of at least 30 days shall be
      given to a 


                                       8
<PAGE>

      stockholder before such redemption of shares and the stockholder will have
      30 days (or such longer period as is specified in the resolution) from the
      date of the notice to avoid such redemption by increasing his account to
      at least 25 Shares, or such lesser number of Shares as is specified in the
      resolution.

            SECTION 4. Notwithstanding any provision of Maryland law requiring
any action to be taken or authorized by the affirmative vote of the holders of a
designated proportion greater than a majority of the Shares outstanding or of
the votes entitled to be cast, such action shall be effective and valid if taken
or authorized by the affirmative vote of the holders of a majority of the total
number of Shares outstanding or entitled to vote thereon pursuant to the
provisions of these Articles of Incorporation.

            SECTION 5. No holder of stock of the Corporation shall, as such
holder, have any right to purchase or subscribe for any Shares which the
Corporation may issue or sell (whether out of the number of Shares now or
hereafter authorized by these Articles of Incorporation, or any amendment
thereof, or out of any Shares acquired by the Corporation after the issue
thereof, or otherwise) other than such right, if any, as the Board of Directors,
in its discretion, may determine.

                                   ARTICLE VI

            The current number of directors of the Corporation is eight, and the
names of those who shall act as such until their successors are duly elected and
qualify are as follows:

                               Robert S. Dow
                               E. Wayne Nordberg
                               E. Thayer Bigelow
                               Stewart S. Dixon
                               John C. Jansing
                               C. Alan MacDonald
                               Hansel B. Millican
                               Thomas J. Neff


                                       9
<PAGE>

However, the By-Laws of the Corporation may fix the number of directors at a
number other than eight and may authorize the Board of Directors, by the vote of
a majority of the entire Board of Directors, to divide the Board into classes,
to increase or decrease the number of directors within a limit specified in the
By-Laws, provided that in no case shall the number of directors be less than
three, and to fill the vacancies created by any such increase in the number of
directors. Unless otherwise provided in the By-Laws of the Corporation, the
directors of the Corporation need not be stockholders.

                                   ARTICLE VII

            The following provisions are inserted for the management of the
business and conduct of the affairs of the Corporation, and to create, define,
limit and regulate the powers of the Corporation, the directors and the
stockholders.

            SECTION 1. In furtherance and not in limitation of the powers
conferred by the statute and pursuant to these Articles of Incorporation, the
Board of Directors is expressly authorized to do the following:

            (a) To make, adopt, alter, amend and repeal By-Laws of the
      Corporation.

            (b) To declare (from interest, dividends or other income received or
      accrued, from accruals of original issue or other discounts on obligations
      held, from capital or other profits on portfolio assets whether realized
      or unrealized, from surplus whether earned, capital or paid in from any
      other lawful sources with respect to a particular Class) dividends and
      distributions on the Corporation's Shares, with respect to such Class, for
      payment in cash, property or the Corporation's own stock to stockholders
      of record on such dates (which may be as frequently as every day) and
      payable at such intervals as the Board of Directors shall determine at any
      time in advance of such payment, whether or not the amount of such payment
      can at that time be determined or must be calculated subsequent to
      declaration and prior to payment by reference to amounts or other factors
      not yet determined at the time of declaration (including but not limited
      to the amount of a dividend or distribution to be determined only be
      reference to what is sufficient to enable the Corporation to qualify as a
      regulated investment company under the United States Internal Revenue Code
      or to avoid liability for Federal income tax); provided that if a dividend
      is paid from any source other than earned 


                                       10
<PAGE>

      surplus, the source of the dividend shall be disclosed not later than at
      the time of payment to the stockholders of such Class or Classes who
      receive it (the authority granted by this subsection (b) to permit,
      without limitation, and if otherwise lawful: the declaration of dividends
      or distributions by means of a formula or other similar method of
      determination whether or not the amount of such dividend or distribution
      can be calculated at the time of such declaration; establishing record or
      payment dates for dividends or distributions on any basis, including
      establishing a number of record or payment dates subsequent to the
      declaration at any dividend or distribution; establishing the same payment
      date for any number of dividends or distributions declared prior to such
      date; providing for the payment of dividends or distributions declared and
      as yet unpaid to stockholders of the Corporation redeeming shares prior to
      the payment date otherwise applicable; and providing in advance for the
      conditions under which any dividend or distribution may be payable in the
      Corporation's own shares to all or less than all of the Corporation's
      stockholders with respect to a particular Class and for the calculation of
      any transfer from earned surplus to capital surplus in excess of the
      transfer to the stated capital of the aggregate par value of the shares of
      a particular Class so to be issued, whether such dividend or distribution
      is in authorized but unissued or in treasury shares of the Corporation).

            (c) To issue and sell or to cause the issuance and sale of Shares,
      of any Class, in such amounts and on such terms and conditions, for such
      purpose and for such amount or kind of consideration as is now or
      hereafter permitted by the laws of the State of Maryland and in accordance
      with the Investment Company Act of 1940.

            (d) To purchase and to cause to be purchased Shares, of any Class,
      pursuant to these Articles of Incorporation, upon tender thereof by the
      holder or holders thereof or otherwise, provided the Corporation has
      assets belonging to that Class legally available for such purpose whether
      arising out of paid-in surplus, other surplus, net profits or otherwise,
      to such extent and in such manner and upon such terms as the Board of
      Directors shall deem expedient, and to pay for such Shares in cash
      belonging to that Class then held or owned by the Corporation.

            (e) To authorize, subject to such vote, consent, or approval of
      stockholders and other conditions, if any, as may be required by any
      applicable statute, rule or regulation, the execution and performance by
      the Corporation of an agreement or agreements with any person,
      corporation, association, partnership, or other organization whereby,
      subject to the supervision and control of the Board of 


                                       11
<PAGE>

      Directors, any such other person, corporation, association, partnership,
      or other organization, shall render managerial, investment advisory and
      related services to the Corporation (including, if deemed advisable, the
      management or supervision of the investment portfolios of the Corporation)
      upon such terms and conditions as may be provided in such agreement or
      agreements.

            (f) To authorize, subject to such vote, consent or approval of
      stockholders and other conditions, if any, as may be required by any
      applicable statute, rule or regulation, the execution and performance by
      the Corporation of an agreement or agreements, which may be exclusive,
      with any person, corporation, association, partnership or other
      organization, as distributor, providing for the sale and distribution of
      the Shares. Such agreement or agreements may provide for the charge by the
      Corporation of a premium over the net asset value (determined as
      hereinafter provided) of such Shares and allowance of a discount by the
      Corporation to such distributor, and may further provide for the
      reallowance by such distributor of concessions or commissions from but not
      exceeding such discount; provided, however, that such discount shall not
      exceed the amount of the premium. Such agreement may also provide for the
      payment of certain distribution expenses by the Corporation.

            (g) To authorize any agreement of the character described in
      subsection (e) or (f) of this Section 1 with any person, corporation,
      association, partnership or other organization, although one or more of
      the members of the Board of Directors or officers of the Corporation may
      be the other party to any such agreement or an officer, director,
      shareholder, or member of such other party, and no such agreement shall be
      invalidated or rendered voidable by reason of the existence of any such
      relationship. Any director of the Corporation who is also a director or
      officer of such corporation or who is so interested may be counted in
      determining the existence of a quorum at any meeting of the Board of
      Directors which shall authorize any such agreement, and may vote thereat
      to authorize any such contract or transaction, with like force and effect
      as if he were not such director or officer of such other corporation or
      not so interested. Any agreement entered into pursuant to said subsections
      (e) or (f) shall be consistent with and subject to the requirements of the
      Investment Company Act of 1940 (including any amendment thereof or other
      applicable Act of Congress hereafter enacted), and no amendment to any
      agreement entered into pursuant to said subsection (e) (other than an

      voting securities of the Corporation (and of each Class affected by such
      amendment) as such phrase is defined in the Investment Company Act of
      1940.

            SECTION 2. The Board of Directors may authorize the purchase by the
Corporation, either directly or through any agent, of the Shares, of any Class,
in the open market or otherwise, at prices not in excess of the net asset value
of such Shares (determined as hereinafter provided) as of a time determined by
the Board of Directors reasonably proximate to the time of purchase by the
Corporation or any such agent.

            SECTION 3. For the purposes referred to in these Articles of
Incorporation, the net asset value of the Shares of a particular Class as of any
particular time shall be determined by or pursuant to the direction of the Board
of Directors as follows:

            (a) The net asset value of each Share, of any Class, at any
      particular time, shall be the quotient, carried out to not less than two
      decimal points, obtained by dividing the net value of the assets of the
      Corporation belonging to that Class (determined as hereinafter provided)
      as of such determination time by the total number of Shares of that Class
      then outstanding, including all Shares of that Class which the Corporation
      has agreed to sell for which the price has been determined, and excluding
      Shares of that Class which have been surrendered to the Corporation or an
      agent and which the Corporation has agreed to purchase, for which the
      price has been determined.

            The net value of the assets of the Corporation of a Class as of any
      such determination time shall be determined in accordance with sound
      accounting practice by deducting from the gross value of the assets of the
      Corporation belonging to that Class (determined as hereinafter provided)
      at such time, the amount of all liabilities belonging to that Class,
      including accrued expenses, such reserves as may be set up to cover taxes
      and any other liabilities, and such other deductions belonging to such
      Class as in the opinion of the Board of Directors of the Corporation are
      in accordance with sound accounting practice.

            The gross value of the assets of the Corporation of a Class at any
      such determination time shall be an amount equal to all cash, receivables,
      the market value of all securities for which market quotations are readily
      available and the fair value of other assets of the Corporation belonging
      to that Class at such determination time, all determined in accordance
      with sound accounting practice and giving effect to the following:


                                       13
<PAGE>

                  (1) the market value as of any such determination time of any
            security owned by the Corporation which is traded in the NASDAQ
            National Market System or is listed or admitted to trading
            privileges on the New York Stock Exchange or the American Stock
            Exchange shall be the last sale price or (in the case of a security
            in which there has been no previously reported sale transaction
            since the last determination time) the mean between the last bid
            price and the last asked price, for such security on such exchange
            or in such market system. In case securities being valued are listed
            or admitted to trading privileges on any securities exchange other
            than the New York Stock Exchange, the American Stock Exchange, or
            the NASDAQ National Market System, the securities exchange, sale
            transactions or bid or asked prices which are to be used as
            aforesaid shall be selected by the Board of Directors or any officer
            or other person designated by the Board of Directors for the
            purpose.

                  (2) The market value of securities traded in an
            over-the-counter market and not traded in the NASDAQ National Market
            System, shall be the mean between the last bid and asked price in
            such market prior to such determination time.

                  (3) The market value of other property, including any
            securities which are neither listed nor admitted to trading
            privileges on any exchange or traded in an over-the-counter market,
            shall be determined in good faith in such manner as the Board of
            Directors shall prescribe from time to time.

                  (4) The determination of the market value of securities
            hereunder may be made in reliance on any recognized source of
            quotations or basis for ascertaining quotations.

                  (5) If a security is traded in more than one market, a
            determination may be made as to which market most accurately
            reflects the value of such security.

            (b) The Board of Directors is empowered, in its discretion, to
      establish other methods for determining such net asset value whenever such
      other methods are deemed by it to be necessary or desirable, including,
      but without limiting the generality of the foregoing, any method deemed
      necessary or desirable in order to 


                                       14

      enable the Corporation to comply with any provision of the Investment
      Company Act of 1940 or any rule or regulation thereunder.

            SECTION 4. The presence in person or by proxy of the holders of
one-third of the Shares of all Classes issued and outstanding and entitled to
vote thereat shall constitute a quorum for the transaction of any business at
all meetings of the shareholders, except as otherwise provided by law or in
these Articles of Incorporation and except that where the holders of Shares of
any Class are entitled to a separate vote as a Class (a "Separate Class") or
where the holders of Shares of two or more (but not all) Classes are required to
vote as a single class (a "Combined Class"), the presence in person or by proxy
of the holders of one-third of the Shares of that Separate Class or Combined
Class, as the case may be, issued and outstanding and entitled to vote thereat
shall constitute a quorum for such vote. If, however, a quorum with respect to
all Classes, a Separate Class or a Combined Class, as the case may be, shall not
be present or represented at any meeting of the shareholders, the holders of a
majority of the Shares of all Classes, such Separate Class or such Combined
Class, as the case may be, present in person or by proxy and entitled to vote
shall have power to adjourn the meeting from time to time as to all Classes,
such Separate Class or such Combined Class, as the case may be, without notice
other than announcement at the meeting, until the requisite number of Shares
entitled to vote at such meeting shall be present. At such adjourned meeting at
which the requisite number of Shares entitled to vote thereat shall be
represented any business may be transacted which might have been transacted at
the meeting as originally notified. The absence from any meeting of stockholders
of the number of Shares in excess of one-third of the Shares of all Classes or
of the affected Class or Classes, as the case may be, which may be required by
the laws of the State of Maryland, the Investment Company Act of 1940 or any
other applicable law, or by these Articles of Incorporation, for action upon any
given matter shall not prevent action at such meeting upon any other matter or
matters which may properly come before the meeting, if there shall be present
thereat, in person or by proxy, holders of the number of Shares required for
action in respect of such other matter or matters.

            SECTION 5. Any determination as to any of the following matters made
by or pursuant to the direction of the Board of Directors consistent with these
Articles of Incorporation and in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of duties, shall be final and conclusive
and shall be binding upon the Corporation and every holder of the Shares, of any
Class, namely, the amount of the assets, obligations, liabilities and expenses
of the Corporation belonging to any Class; the amount of the net income of the
Corporation from dividends and interest for any period and the amount of assets
at any time legally available for the payment of dividends with respect to any
Class; the amount of paid-in surplus, other surplus, annual or other net
profits, or net assets in excess of capital, undivided profits, or excess of
profits over losses 


                                       16

on sales of securities belonging to any Class; the amount, purpose, time of
creation, increase or decrease, alteration or cancellation of any reserves or
charges and the propriety thereof (whether or not any obligation or liability
for which such reserves or charges shall have been created shall have been paid
or discharged) with respect to any Class; the market value, or any sale, bid or
asked price to be applied in determining the market value, of any security owned
or held by the Corporation with respect to any Class; the fair value of any
asset owned by the Corporation; the number of Shares of the Corporation of any
Class issued or outstanding; the existence of conditions permitting the
postponement of payment of the repurchase price of Shares of Class or the
suspension of the right of redemption as provided by law; any matter relating to
the acquisition, holding and disposition of securities and other assets by the
Corporation belonging to any Class; any question as to whether any transaction
constitutes a purchase of securities on margin, a short sale of securities, or
an underwriting of the sale of, or participation in any underwriting or selling
group in connection with the public distribution of any securities; and any
matter relating to the issue, sale, repurchase and/or other acquisition or
disposition of Shares of any Class.

            SECTION 6. The Corporation is adopting its corporate title through
permission of the firm of Lord, Abbett & Co., which is entering into a
management or advisory contract with the Corporation. Such contract shall make
appropriate provisions that upon the termination of such contract for any cause,
or if such firm or subsidiary or affiliate or successor deems it advisable to
withdraw the right to the use of its name, the Corporation will, at the request
of such firm or a subsidiary, affiliate or successor lawfully using the name,
take such action as may be necessary to change its name to eliminate all use of
or reference to the words "Lord Abbett" in any form and will not use the
registered service mark of Lord, Abbett & Co., without the written consent of
such firm, subsidiary, affiliate or successor. The Corporation shall also agree
in such contract that investment companies other than the Corporation for which
such firm or a subsidiary successor may act as investment adviser, and other
companies affiliated with Lord, Abbett & Co., may be formed with the words "Lord
Abbett" in their corporate titles. Such agreements on the part of the
Corporation are hereby made binding upon it, its directors, officers,
stockholders, creditors and all other persons claiming under or through it.

            To the fullest extent permitted by Maryland statutory or decisional
law, as amended from time to time, no director or officer of the Corporation

extent such exemption from liability or limitation thereof is not permitted by
the Investment Company Act of 1940, as amended from time to time. No amendment

time conferred upon the stockholders of the Corporation by these Articles of

Company  Act  of  1940  or  any  other   applicable   law  or  the  Articles  of
Incorporation, for action upon any given matter shall not prevent action of such
meeting  upon any other  matter or matters  which may  properly  come before the
meeting,  if there shall be present thereat,  in person or by proxy,  holders of
the number of Shares required for action in respect of such matter or matters.

of  Incorporation or by these By-Laws and except that with respect to a question
as to which  the  holders  of Shares of any Class or  Classes  are  entitled  or
required to vote as a Separate  Class or a Combined  Class,  as the case may be,
such question shall be decided as to such Separate Class or such Combined Class,
as the case may be, by a majority  of the votes cast by Shares of such  Separate
Class or such Combined Class, as the case may be.
                  With  respect  to  all  Shares  having  voting  rights  (a)  a
shareholder  may vote the  Shares  owned of record by him either in person or by

its date unless  otherwise  provided in the proxy and (b) in all  elections  for
directors every shareholder shall have the right to vote, in person or by proxy,
the Shares owned of record by him, for as many persons as there are directors to
be elected and for whose election he has a right to vote.

                                   ARTICLE III

                  Section 1. General Powers. The property,  affairs and business
of the  corporation  shall  be  managed  by the  Board of  Directors,  provided,
however, that the Board of Directors may authorize the Corporation to enter into
an  agreement  or  agreements   with  any  person,   corporation,   association,
partnership  or other  organization,  subject  to the  Board's  supervision  and

of the  Board  there  shall be less than a quorum  present,  a  majority  of the
directors present may adjourn the meeting from time to time until a quorum shall

majority of the whole Board,  may elect directors to fill vacancies in the Board
resulting  from an increase in the number of  directors or from any other cause.
Directors  so chosen  shall hold office until their  respective  successors  are
elected and qualify,  unless sooner displaced  pursuant to law or these By-Laws.
The  stockholders,  at any meeting called for the purpose,  may, with or without
cause,  remove any director by the affirmative vote of the holders of a majority
of the votes  entitled to be cast, and at any meeting called for the purpose may
fill the vacancy in the Board thus caused.
                  Section 4. Regular Meetings.  Regular meetings of the Board of
Directors  shall be held at such time and place,  within or without the State of
Maryland, as may from time to time be fixed by Resolution of the Board or as may

President, any Vice President or any two directors.  Each special meeting of the
Board  shall be held at such  place,  either  within or  outside of the State of
Maryland,  as shall be designated in the notice of such meeting.  Notice of each
such meeting shall be mailed to each  director,  at his residence or usual place
of  business,  at least  two days  before  the day of the  meeting,  or shall be
directed to him at such place by  telegraph  or cable,  or be  delivered  to him
personally  not later  than the day before  the day of the  meeting.  Every such
notice  shall  state  the time and place of the  meeting  but need not state the
purposes thereof,  except as otherwise expressly provided in these By-Laws or by
statute.
                  Section 6. Telephonic Conference Meetings.  Any meeting of the
Board or any committee thereof may be held by conference  telephone,  regardless
where each  director  may be located at the time,  by means of which all persons
participating  in the  meeting can hear each other,  and  participation  in such
meeting in such manner  shall  constitute  presence  in person at such  meeting,
except  where the  Investment  Company  Act of 1940,  as  amended,  specifically
requires that the vote of such director be cast in person.
                  Section 7. Fees and Expenses. The directors shall receive such
fees and expenses for services to the  Corporation  as may be fixed by the Board
of Directors,  subject  however,  to such  limitations as may be provided in the
Articles of  Incorporation.  Nothing  herein  contained  shall be  construed  to
preclude any director from serving the  Corporation  in any other capacity as an
officer, agent or otherwise and receiving compensation therefor.

                  Section 8.  Transactions  with Directors.  Except as otherwise
provided  by  law  or in  the  Articles  of  Incorporation,  a  director  of the
Corporation  shall not in the  absence of fraud be  disqualified  from office by
dealing or contracting  with the  Corporation  either as a vendor,  purchaser or
otherwise,  nor in the absence of fraud shall any transaction or contract of the
Corporation  be void or  voidable  or  affected  by  reason of the fact that any
director,  or any firm of which any director is a member,  or any corporation of
which  any  director  is an  officer,  director  or  stockholder,  is in any way
interested in such transaction or contract;  provided that at the meeting of the
Board of  Directors,  at which said  contract or  transaction  is  authorized or
confirmed, the existence of an interest of such director, firm or corporation is
disclosed  or made  known  and there  shall be  present a quorum of the Board of
Directors a majority of which, consisting of directors not so interested,  shall
approve  such  contract  or  transaction.  Nor shall any  director  be liable to
account to the  Corporation  for any profit  realized by him from or through any
such  transaction  or  contract  of the  Corporation  ratified  or  approved  as
aforesaid, by reason of the fact that he or any firm of which he is a member, or
any  corporation  of which  he is an  officer,  director,  or  stockholder,  was
interested  in such  transaction  or contract.  Directors so  interested  may be
counted when  present at meetings of the Board of  Directors  for the purpose of
determining the existence of a quorum.  Any contract,  transaction or act of the
Corporation or of the Board of Directors (whether or not approved or ratified as
hereinabove provided) which shall be ratified by a majority of the votes cast at
any  annual or  special  meeting  at which a quorum is  present  called for such
purpose,  or approved  in writing by a majority in interest of the  stockholders
having voting power without a meeting,  shall,  except as otherwise  provided by
law,  be valid and as binding as though  ratified  by every  stockholder  of the
Corporation.


<PAGE>



                  Section  9.  Committees.   The  Board  of  Directors  may,  by
resolution  adopted  by a majority  of the whole  Board,  designate  one or more
committees  each such  committee  to  consist  of two or more  directors  of the
Corporation,  which,  to the  extent  permitted  by law  and  provided  in  said
resolution,  shall  have and may  exercise  the  powers  of the  Board  over the
business and affairs of the  Corporation,  and may have power to  authorize  the
seal of the  Corporation  to be affixed to all papers which may require it. Such
committee or committees  shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors.  A majority of the
members  of any such  committee  may  determine  its action and fix the time and
place of its meetings,  unless the Board of Directors shall  otherwise  provide.
The Board of Directors shall have power at any time to change the membership of,
to fill vacancies in, or to dissolve any such committee.
                  Section 10. Written Consents. Any action required or permitted
to be taken at any meeting of the Board of Directors or by any committee thereof
may be taken without a meeting,  if a written  consent  thereto is signed by all
members of the Board or of such committee,  as the case may be, and such written
consent is filed with the minutes or proceedings of the Board or committee.


<PAGE>



                  Section 11. Waiver of Notice. Whenever under the provisions of
these By-Laws, or of the Articles of Incorporation, or of any of the laws of the
State of  Maryland,  or other  applicable  statue,  the  Board of  Directors  is
authorized  to hold any  meeting  or take any action  after  notice or after the
lapse of any prescribed period of time, a waiver thereof, in writing,  signed by
the person or persons  entitled to such notice or lapse of time,  whether signed
before or after the time of meeting  or action  stated  herein,  shall be deemed
equivalent thereto.  The presence at any meeting of a person or persons entitled
to notice  thereof  shall be deemed a waiver of such notice as to such person or
persons.

                                   ARTICLE IV
                                    OFFICERS
                  Section 1.  Number  and  Designation.  The Board of  Directors
shall each year appoint  from among their  members a Chairman and a President of
the Corporation,  and shall appoint one or more Vice Presidents, a Secretary and
a Treasurer and, from time to time, any other officers and agents as it may deem
proper.  Any two of the above mentioned  offices,  except those of the President
and a Vice  President,  may be held by the same  person,  but no  officer  shall
execute,  acknowledge or verify any instrument in more than one capacity if such
instrument be required by law or by these  By-Laws to be executed,  acknowledged
or verified by any two or more officers.
                  Section 2. Term of Office.  The term of office of all officers
shall be one year or until  their  respective  successors  are  chosen;  but any
officer or agent chosen or  appointed by the Board of Directors  may be removed,
with or without cause, at any time, by the affirmative vote of a majority of the
members of the Board then in office.


<PAGE>





                  Section 3. Duties. Subject to such limitations as the Board of
Directors may from time to time prescribe, the officers of the Corporation shall
each have such  powers and duties as  generally  appertain  to their  respective
offices, as well as such powers and duties as from time to time may be conferred
by the Board of Directors.

                              CERTIFICATE OF STOCK
                  Section  1.  Form  and  Issuance.   Each  stockholder  of  the
Corporation,  of a  particular  Class,  shall be  entitled  upon  request,  to a
certificate  or  certificates,  in such form as the Board of Directors  may from
time to time  prescribe,  which shall represent and certify the number of shares
of stock of the  Corporation  of that Class of stock owned by such  stockholder.
The  certificates  for  shares  of  stock  of the  Corporation  shall  bear  the
signature,  either  manual or  facsimile,  of the  Chairman  of the  Board,  the
President or a Vice President and the Treasurer or an Assistant Treasurer or the
Secretary  or an Assistant  Secretary,  and shall be sealed with the seal of the
Corporation  or bear a  facsimile  of  such  seal.  The  validity  of any  stock
certificate shall not be affected if any officer whose signature appears thereon
ceases to be an officer of the Corporation before such certificate is issued.


<PAGE>





                  Section  2.  Transfer  of  Stock.  The  shares of stock of the
Corporation of any Class shall be  transferable  on the books of the Corporation
by the holder thereof in person or by a duly authorized attorney, upon surrender
for  cancellation of a certificate or certificates  for a like number of shares,
with a duly  executed  assignment  and power of  transfer  endorsed  thereon  or
attached thereto, or, if no certificate has been issued to the holder in respect
of shares of stock of the  Corporation,  upon  receipt of written  instructions,
signed by such holder,  to transfer  such shares from the account  maintained in
the name of such  holder by the  Corporation  or its  agent.  Such  proof of the
authenticity  of the  signatures as the  Corporation or its agent may reasonably
require shall be provided.


<PAGE>





                  Section 3. Lost, Stolen, Destroyed and Mutilated Certificates.
The holder of any stock of the Corporation of any Class shall immediately notify
the Corporation of any loss, theft, destruction or mutilation of any certificate
therefore, and the Board of Directors may, in its discretion, cause to be issued
to him a new certificate or  certificates  of stock of the same Class,  upon the
surrender of the mutilated  certificate or in case of loss, theft or destruction
of the certificate upon satisfactory proof of such loss, theft or destruction of
the certificate upon satisfactory proof of such loss, theft, or destruction; and
the Board of Directors  may, in its  discretion,  require the owner of the lost,
stolen or destroyed certificate,  or his legal  representatives,  to give to the
Corporation  and to such  registrar or transfer  agent as may be  authorized  or
required to countersign such new certificate or certificates a bond, in such sum
as they may direct,  and with such surety or  sureties,  as they may direct,  as
indemnity  against  any claim  that may be made  against  them or any of them on
account of or in connection with the alleged loss,  theft, or destruction of any
such certificate.


<PAGE>



                  Section 4. Record  Date.  The Board of  Directors  may fix, in
advance, a date as the record date for the purpose of determining  stockholders,
of any Class,  entitled to notice of, or to vote at, any meeting of stockholders
of any Class,  or  stockholders  of any Class entitled to receive payment of any
dividend or the allotment of any rights,  or in order to make a determination of
stockholders of any Class for any other proper purpose.  Such date, in any case,
shall be not more than 90 days,  and in case of a meeting of  stockholders,  not
less than 10 days,  prior to the date on which the particular  action  requiring
such  determination  of  stockholders is to be taken. In lieu of fixing a record
date,  the Board of Directors may provide that the stock transfer books shall be
closed for a stated period but not to exceed,  in any case, 20 days prior to the
date of any  meeting of  stockholders  or the date for payment of any divided or
the allotment of rights.  If the stock transfer books are closed for the purpose
of  determining  stockholders  entitled  to notice of or to vote at a meeting of
stockholders,  such  books  shall be  closed  for at  least 10 days  immediately
preceding such meeting.  If no record date for the determination of stockholders
entitled to notice of, or to vote at, a meeting of stockholders  shall be at the
close of business on the day on which notice of the meeting is mailed or the day
30 days before the meeting, whichever is the closer date to the meeting, and the
record date for the determination of stockholders entitled to receive payment of
a dividend or an  allotment  of any rights  shall be at the close of business on
the day on which the resolution of the Board of Directors declaring the dividend
or allotment of rights is adopted,  provided that the payment or allotment  date
shall  not be  more  than  90  days  after  the  date  of the  adoption  of such
resolution.

                                   ARTICLE VI
                                 CORPORATE BOOKS
                  The books of the  Corporation may be kept outside the State of
Maryland at such place or places as the Board of Directors may from time to time
determine.  The original or duplicate  stock ledger shall be  maintained  at the
office of the Corporation's transfer agent.

                                   ARTICLE VII
                                   SIGNATURES



                  Except as otherwise  provided in these By-Laws or as the Board
of Directors  may  generally or in  particular  cases  authorize  the  execution
thereof in some other manner, all deeds, leases,  transfers,  contracts,  bonds,
notes,  checks,  drafts and other obligations made,  accepted or endorsed by the
Corporation and all endorsements,  assignments, transfers, stock powers or other
instruments  of transfer of  securities  owned by or standing in the name of the
Corporation shall be signed or executed by two officers of the Corporation,  who
shall be the Chairman,  the President or a Vice President and a Vice  President,
the Secretary or the Treasurer.

                                  ARTICLE VIII
                                   FISCAL YEAR

resolution of the Board of Directors of the Corporation.

                                 CORPORATE SEAL
                  The corporate seal of the Corporation  shall consist of a flat
faced  circular  die  with  the word  "Maryland"  together  with the name of the
Corporation, the year of its organization,  and such other appropriate legend as
the Board of Directors may from time to time determine, cut or engraved thereon.
In lieu of the corporate seal, when so authorized by the Board of Directors or a
duly  empowered  committee  thereof,  a facsimile  thereof may be  impressed  or
affixed or reproduced.

suit or proceeding, whether civil, criminal, administrative or investigative, in
which the director  was, is, or is  threatened  to be made a named  defendant or

penalty,  fine,  settlement and  reasonable  expense so incurred by the director
shall be paid by the Corporation or, if paid by the director,  reimbursed to the

imposed by the applicable  provisions of Section 2-418 of the  Corporations  and
Associations  Article of the Annotated  Code of the State of Maryland and by the

as  interpreted  and as required to be  implemented  by Securities  and Exchange
Commission  Release No.  IC-11330 of September 4, 1980. The foregoing  shall not
limit  the  authority  of the  Corporation  to  indemnify  any of its  officers,
employees, or agents to the extent consistent with applicable law.
