Dear Shareholders of the Berger/BIAM IPT - International Fund:

         A Special Meeting of Shareholders of the Fund has been scheduled for
Friday, May 5, 2000. At the meeting, shareholders will be asked to approve a new
Investment Advisory Agreement and a new Sub-Advisory Agreement for the Fund.
More detail is contained in the accompanying Proxy Statement.

         Recently, Berger LLC (Berger) and Bank of Ireland Asset Management
(U.S.) Limited (BIAM) announced their intention to dissolve their joint venture
BBOI Worldwide LLC (BBOI). Currently, Berger and BIAM provide investment
advisory, sub-advisory and administrative services to the Fund through BBOI. By
dissolving BBOI, Berger and BIAM are proposing to provide those services to the
Fund directly, instead of through BBOI. Thus, you are being asked to approve new
agreements so that investment advisory and sub-advisory services for the Fund
are provided directly by Berger and BIAM.

         The investment advisory fee borne by the Fund will also be decreased
under the new agreements. No change is proposed for any other fees borne by the
Fund. In addition, the investment objective, policies and restrictions of the
Fund will not change as a result of the new agreements. BIAM will continue to be
responsible for day-to-day management of the Fund.

         Accompanying this letter is a proxy statement, voting instruction card
and business reply envelope. Please take a moment to look over the material and
cast your vote on the proposals put forth.

         YOUR VOTE IS IMPORTANT. WHETHER OR NOT YOU PLAN TO ATTEND THE MEETING
IN PERSON, PLEASE SIGN THE ENCLOSED VOTING INSTRUCTION CARD AND RETURN IT AS
SOON AS POSSIBLE IN THE ACCOMPANYING POSTAGE-PAID ENVELOPE. THE TRUSTEES OF THE
FUND RECOMMEND THAT YOU VOTE "FOR" THE PROPOSALS.

         The Fund has enlisted the services of Shareholder Communications
Corporation ("SCC"), a professional proxy solicitation firm, to assist with the
proxy process. As the meeting date approaches, you may receive a call from SCC
encouraging you to exercise your right to vote.

         Again, we urge you to review the enclosed proxy material and vote
utilizing one of the convenient methods found on the voting instruction card.

         If you have any questions regarding the enclosed material or the
execution of your vote, please do not hesitate to call 1-800-634-9899. Thank you
for taking the time to consider these important proposals and for your
investment in the Fund.

                                                          Sincerely,

                                                          /s/  Jack R. Thompson

           IMPORTANT INFORMATION FOR VARIABLE ANNUITY CONTRACT OWNERS
                    AND VARIABLE LIFE INSURANCE POLICY OWNERS


- --------------------------------------------------------------------------------

         These materials are for a special shareholders' meeting scheduled for
May 5, 2000, at 11:00 a.m., Mountain time, relating to the Berger/BIAM IPT -
International Fund, a series of Berger Institutional Products Trust. They
discuss the proposals to be voted on at the meeting, and contain a proxy
statement and voting instruction card. A voting instruction card is, in essence,
a ballot. When you complete your voting instruction card, it tells your
insurance company how to vote its proxy on important issues relating to the
portion of your account that is allocated to the Fund.

If you complete and sign the voting instruction card, the shares will be voted
exactly as you instruct. If you simply sign and return the voting instruction
card, the shares will be voted in accordance with the Trustees' recommendations.
If you do not return a voting instruction card at all, the shares will be voted
in the same proportion as shares for which instructions have been received from
other variable annuity contract holders and variable life insurance
policyholders.

- --------------------------------------------------------------------------------

WE URGE YOU TO SPEND A FEW MINUTES REVIEWING THE PROPOSALS IN THE PROXY
STATEMENT. THEN, FILL OUT THE VOTING INSTRUCTION CARD AND RETURN IT IN THE
ENVELOPE PROVIDED.

                                 PROXY STATEMENT
                     FOR THE SPECIAL MEETING OF SHAREHOLDERS

                            TO BE HELD ON MAY 5, 2000

         This Proxy Statement is furnished in connection with the solicitation
of proxies by the Trustees of Berger Institutional Products Trust (the Trust),
to be used at the Special Meeting of Shareholders of the outstanding series of
the Trust known as the Berger/BIAM IPT - International Fund (the Fund) to be
held on May 5, 2000, at 11:00 a.m. (local time), at the Four Points Sheraton
Hotel, 600 South Colorado Blvd., 1st Floor Tree Room, Denver, Colorado, for the
purposes set forth in the accompanying Notice of Special Meeting of
Shareholders, as further described below.

         Shares of the Fund are not offered directly to the public, but are sold
only in connection with investment in and payments under variable annuity
contracts and variable life insurance contracts (Variable Contracts) issued by
certain life insurance companies (Participating Insurance Companies). As a
result, the separate accounts of the Participating Insurance Companies, rather
than individual owners of Variable Contracts (Contract Owners), are the
shareholders of the Fund entitled to vote on the Proposals at the meeting.
However, under current law, a Participating Insurance Company is required to
request voting instructions from its Contract Owners and must vote Fund shares
held by each of its separate accounts in proportion to the voting instructions
received. Accordingly, Participating Insurance Companies are soliciting voting
instructions from the Contract Owners of the Variable Contracts with respect to
the matters set forth in this Proxy Statement. In connection with the
solicitation of voting instructions, the Participating Insurance Companies will
furnish a copy of this Proxy Statement to all Contract Owners.

         Shareholders of the Fund of record at the close of business on March 6,
2000 (the Record Date), are entitled to attend and to vote at the meeting and at
any and all adjournments of the meeting. On the Record Date, there were
outstanding 456,421 shares of the Berger/BIAM IPT - International Fund. These
shares constitute all of the outstanding shares of the Trust entitled to vote at
the meeting. Each proposal and each item of other business which may properly
come before the meeting will be voted on separately. Each share is entitled to
one vote and each fractional share shall be entitled to a fractional vote.

         On the Record Date, separate accounts of Participating Insurance
Companies were the only shareholders of the Fund. As noted above, Contract
Owners are indirectly invested in the Fund through their Variable Contracts and
have the right to instruct their Participating Insurance Companies how to vote
shares of the Fund on all matters requiring a vote of shareholders. Contract
Owners indirectly invested in the Fund at the close of business on the Record
Date will be entitled to notice of the meeting and to instruct their
Participating Insurance Companies how to vote the number of shares of the Fund
attributable to their Variable Contracts at the meeting.

         Contract Owners may use the voting instruction card included with this
Proxy Statement to instruct their Participating Insurance Companies how to vote
those shares attributable to their Variable Contracts as of the Record Date.
Participating Insurance Companies will vote the shares held in their respective
separate accounts at the meeting in accordance with their respective Contract
Owners' instructions.

         If the accompanying voting instruction card is properly executed,
returned in time to be voted at the meeting and not revoked, the relevant
Participating Insurance Company will vote those shares in accordance with the
Contract Owner's instructions marked on the card. If the Contract Owners signs
and returns the voting




                                       1
<PAGE>   6

instruction card, but does not indicate a choice as to the Proposals presented,
the relevant Participating Insurance company will vote the shares in accordance
with the Trustees' recommendations. If a Contract Owner does not return a voting
instruction card at all, the shares attributable to that Contract Owners will be
voted in the same manner and in the same proportion as the shares for which it
has received instructions from other Contract Owners.

         An executed and returned voting instruction card may nevertheless be
revoked by a Contract Owner at any time before it is voted by sending written
notice of the revocation to the Fund or by appearing personally at the meeting
and instructing the Participating Insurance Company in person.

         This Proxy Statement and the accompanying Notice of Special Meeting of
Shareholders and proxy are first being mailed to shareholders of record on or
about March 17, 2000. The Participating Insurance Companies will furnish a copy
of this Proxy Statement and voting instruction card to each of their Contract
Owners to solicit voting instructions.

         The cost of preparing and mailing the Notice of Special Meeting of
Shareholders, the proxy, this Proxy Statement, and any additional proxy
material, will be borne by the Fund's investment advisor, BBOI Worldwide LLC, or
its affiliates, and not by the Fund. The most recently available annual report
of the Fund has been mailed to shareholders. IF YOU HAVE NOT RECEIVED THE REPORT
OR WOULD LIKE TO RECEIVE AN ADDITIONAL COPY, WITHOUT CHARGE, PLEASE WRITE TO THE
FUND AT 210 UNIVERSITY BLVD., SUITE 900, DENVER, COLORADO 80206, OR CALL
1-800-259-2820 AND IT WILL BE SENT BY FIRST-CLASS MAIL.

                         THE PROPOSALS TO BE VOTED UPON

         At the meeting, shareholders will be asked to vote their shares to
approve a new Investment Advisory Agreement and a new Sub-Advisory Agreement
(the Agreements) for the Fund, and to transact such other business as may
properly come before the meeting or any adjournment thereof.

         THE TRUSTEES OF THE TRUST RECOMMEND THAT YOU VOTE FOR THE PROPOSALS, AS
MORE FULLY DESCRIBED BELOW.

         Implementation of the proposed Agreements is contingent upon both
Proposals being approved. In other words, unless both Proposals are approved,
neither of the proposed Agreements will be implemented for the Fund. If the
Proposals are approved, it is anticipated that the new Agreements will be
implemented as soon as practicable after the meeting.

================================================================================

                           BACKGROUND TO THE PROPOSALS

================================================================================

WHY ARE THE NEW AGREEMENTS BEING PROPOSED?

         New Agreements are proposed because Berger LLC (Berger) and Bank of
Ireland Asset Management (U.S.) Limited (BIAM) intend to dissolve their joint
venture BBOI Worldwide LLC (BBOI). BBOI currently serves as investment adviser
to the Fund. By dissolving BBOI, Berger and BIAM desire to begin providing
services for the Fund directly, rather than indirectly as they now do through
BBOI. New Agreements are being proposed to reflect that new arrangement and to
reflect the lower investment advisory fees paid under the Agreements.




                                       2
<PAGE>   7



WHO IS BBOI?

         BBOI is a joint venture company owned 50/50 by Berger and BIAM. In
1996, Berger and BIAM formed BBOI with the intention of creating and servicing
new mutual funds together through BBOI. Currently, BBOI serves as the investment
adviser and administrator to the Fund. BBOI delegates its advisory and
administrative duties to its joint venture partners -- BIAM, which serves as
sub-adviser, and Berger, which serves as sub-administrator. However, Berger and
BIAM have recently decided to dissolve BBOI and desire to provide services to
the Fund directly. Under the proposed new arrangements, BBOI would not serve the
Fund in any capacity.

WHAT NEW ARRANGEMENTS ARE PROPOSED?

         As noted above, Berger and BIAM intend to dissolve BBOI and, subject to
shareholder approval at the meeting, to serve the Fund directly, rather than
through BBOI. Under the new arrangement, Berger would serve as investment
adviser and BIAM as sub-adviser. In addition, the investment advisory fee borne
by the Fund will be lowered, as will the sub-advisory fee paid by Berger to
BIAM.

         In addition to advisory services, BBOI also currently provides for the
Fund administrative services. Under the new arrangement, Berger would be
directly responsible to the Fund for providing those services, rather than being
responsible for them indirectly through BBOI.

         Under the new arrangements, the Fund would also change its name to
Berger IPT - International Fund.

WHY ARE SHAREHOLDERS BEING ASKED TO VOTE?

         A shareholder vote is being requested since the re-alignment of the
companies providing advisory services to the Fund will not include BBOI.
Instead, new Agreements would be signed by Berger and BIAM, rather than BBOI.
The law requires that shareholders be asked to approve the new Investment
Advisory and Sub-Advisory Agreements before they are implemented. Shareholder
approval is not required or being requested to implement the new administrative
services arrangements or name change.

WOULD THIS CHANGE THE AMOUNT OF FEES PAID BY THE FUND?

         Yes, they would be lowered. Currently, the Fund bears an investment
advisory fee at the annual rate of 0.90% of average daily net assets. Under the
new Investment Advisory Agreement, the Fund would bear an investment advisory
fee at the annual rate of 0.85% of the first $500 million of average daily net
assets, 0.80% of the next $500 million, and 0.75% of all amounts in excess of $1
billion. There is no change proposed in the nature or level of any services
being provided to the Fund.

         Shareholders in the Fund do not pay any sales loads, redemption or
exchange fees, but do bear indirectly the Fund's annual fund operating expenses,
which vary from year to year. The following table shows the current annual fund
operating expenses of the Fund as of the last fiscal year end, December 31,
1999, and the pro forma annual fund operating expenses as if the new Investment
Advisory Agreement had been in effect throughout the last fiscal year. The
following expenses do not include any charges or expenses deducted by your
variable insurance contract or retirement plan. Refer to your variable contract
prospectus or retirement plan documents for an explanation of those charges and
expenses.

(1) Under a written contract, the Fund's investment advisor waives its fee and

terminated or amended except by a vote of the Fund's Board of Trustees.

EXAMPLE COSTS

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. They use the same assumptions that other funds use in their prospectuses:

o        $10,000 initial investment
o        5% total return for each year
o        Fund operating expenses remain the same for each period
o        Redemption after the end of each period

Your actual costs may be higher or lower, so these examples should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

the Fund, the Fund's annual operating expenses in any fiscal year, including the
investment advisory fee and custodian fees, but excluding brokerage commissions,
interest, taxes and extraordinary expenses, exceed 1.20% of the Fund's average
daily net assets for that fiscal year. The

contract may not be terminated or amended except by a vote of the Fund's Board
of Trustees. Berger has agreed to sign a written contract limiting the Fund's
expenses at the same level, if the new Agreements are approved and implemented.

         Under the current Sub-Advisory Agreement, BBOI (and not the Fund) is
responsible for paying BIAM a sub-advisory fee at the annual rate of 0.45% of
average daily net assets. During the fiscal year ended December 31, 1999, BIAM
waived a portion of the sub-advisory fees it was entitled to receive under the
Sub-Advisory Agreement. This sub-advisory fee waiver was scheduled to terminate
effective October 15, 2000. During the fiscal year ended December 31, 1999, BIAM
earned $24,630 in sub-advisory fees, of which BBOI paid BIAM $0, after waiver.
Under the new Sub-Advisory Agreement, Berger (and not the Fund) will be
responsible for paying BIAM a sub-advisory fee at the annual rate of 0.45% of
the first $50 million of average daily net assets, 0.40% of the next $50
million, and 0.30% of all amounts in excess of $100 million. If this new
sub-advisory fee had been in effect during the fiscal year ended December 31,
1999, the sub-advisory fee earned by BIAM would not have changed from the amount
earned during that fiscal year.

WOULD THIS CHANGE THE FUND'S INVESTMENT OBJECTIVE OR POLICIES?

         No. The Fund's investment objectives and investment policies,
limitations, restrictions and guidelines are not proposed to change in any
respect.

WOULD THIS CHANGE THE FUND'S DAY-TO-DAY INVESTMENT MANAGEMENT?

         No. As stated above, BIAM will continue as sub-adviser providing the
day-to-day investment management of the Fund, if shareholders approve the new
Agreements.

WOULD THIS CHANGE THE DUTIES OR SERVICES FOR WHICH BERGER AND BIAM ARE EACH
RESPONSIBLE?

         Although there will be no change in the nature or level of services
provided to the Fund, there is proposed to be a change in the alignment of the
companies responsible for providing those services. Currently, BBOI serves both
as investment adviser and administrator to the Fund. BBOI delegates its
investment advisory responsibilities to BIAM, as sub-adviser, and delegates its
administrative duties to Berger, as sub-administrator.

         In contrast, under the new Agreements, Berger will serve directly as
investment adviser to the Fund and, in that capacity, will be responsible for
managing all their investment operations, including overseeing, evaluating and
monitoring any sub-adviser. Berger will also serve directly as the Fund's
administrator. BIAM will continue to be responsible for day-to-day investment
management of the Fund's portfolio in its capacity as sub-adviser.

         The new arrangements will re-align the Fund's service providers in a
way that is more consistent with the other mutual funds in the Berger Funds
family and is believed to be more understandable to investors.

WHAT DID THE TRUSTEES CONSIDER AND WHAT IS THEIR RECOMMENDATION?

         At a meeting held on February 15, 2000, the Trustees of the Trust,
including a majority of the Trustees who are not "interested persons" of the
Fund or BBOI (the Independent Trustees) as defined in the Investment Company Act
of 1940 (1940 Act), approved the new Investment Advisory Agreement with Berger,
and the new Sub-Advisory Agreement between Berger and BIAM, contingent on
shareholder approval. They also approved the new administrative services
arrangements and name change which are not being submitted for shareholder vote.

         In considering whether to approve the Agreements and to recommend
approval to shareholders, the Trustees inquired into a number of matters and
considered various factors. The materials considered by the Trustees included
information regarding Berger and BIAM and their personnel, operations, financial
condition and investment philosophy.




                                       5
<PAGE>   10

         In addition to these and other matters, the Trustees considered:

o        Berger's history as adviser of the Berger Funds and BIAM's reputation
         and track record as sub-adviser of the Fund

o        the fact that the current day-to-day investment management is not
         proposed to change

o        the fact that the investment advisory fee is proposed to be decreased,
         and that the other fees paid or borne by the Fund are not proposed to
         change

o        the fact that under the proposed arrangements, Berger will be directly
         responsible to the Fund for investment advice provided, even though
         day-to-day portfolio management will continue to be the responsibility
         of BIAM

o        the fact that Berger and BIAM have committed to use their best efforts
         to ensure compliance with Section 15(f) of the 1940 Act (see "Section
         15(f) of the Investment Company Act of 1940" below), including avoiding
         any "unfair burden" (as defined in the Act) to the Fund as a result of
         the dissolution of BBOI.

         The Trustees believed it was especially important that the investment
advisory fee is proposed to be decreased and that otherwise, there would no
change to the fees paid or borne by the Fund and no change in the day-to-day
management of the Fund's portfolio. In addition, the fact that Berger and BIAM
would continue to be responsible for the investment advice provided was
considered significant to assuring quality and consistency of investment
management under the new Agreements. Moreover, the Trustees believed it was
important that Berger and BIAM had committed to using best efforts to ensure
compliance with Section 15(f).

         The Trustees recognized that this new arrangement re-aligns the
companies providing services to the Fund, but believed that the proposed
arrangement reflects at least as accurately as the current arrangement the
allocation in practice of responsibilities between Berger and BIAM. In addition,
the Trustees believed that Berger and BIAM are capable of adequately fulfilling
their respective responsibilities in their proposed roles at least as well as in
their current roles.

         Finally, the Trustees also believed there may be an advantage in
understandability and efficiency to having the adviser and sub-adviser
relationships for the Fund more consistent with those applicable to the other
Berger Funds, and believed it is important that the entire cost of the
shareholders' meeting and the preparation and solicitation of proxies is to be
borne by BBOI and not by the Fund or the Trust.

         After examining relevant materials furnished to them, meeting with
executive officers of BBOI and discussing the foregoing factors, the Trustees
(including the Independent Trustees) determined that the proposed Agreements
would be in the best interests of the Fund and its shareholders. Accordingly,
subject to shareholder approval of the Fund, the terms of the Agreements were
unanimously approved by the Trustees (including the Independent Trustees). The
Trustees further directed that the Agreements be submitted to a shareholder vote
with the Trustees' unanimous recommendation for approval.

         If the shareholders of the Fund do not approve both of the Proposals,
the proposed arrangements and Agreements will not be implemented for the Fund,
and the current Investment Advisory Agreement and Sub-Advisory Agreement will
continue in effect. In that event, the Trustees would consider what further
action, if any, should be taken in the best interests of the Fund and its
shareholders.

         THE TRUSTEES UNANIMOUSLY RECOMMEND THAT SHAREHOLDERS VOTE TO APPROVE
THE PROPOSALS.

================================================================================

                               THE NEW AGREEMENTS

================================================================================

WHAT ARE THE KEY PROVISIONS OF THE PROPOSED NEW AGREEMENTS?

         The services provided to the Fund under the new Agreements are, in
substance, the same as those provided under the current Investment Advisory
Agreement and Sub-Advisory Agreement. However, under the new Agreements, instead
of BBOI acting as adviser and delegating all of its duties to BIAM as
sub-adviser, Berger will act as adviser and engage BIAM as sub-adviser.
Following is a brief description of some of the key provisions of the new
Agreements.

         Advisory Services. Under the proposed new Investment Advisory
Agreement, Berger will be responsible, as adviser, for the same duties that BBOI
is responsible for under the current Investment Advisory Agreement. In general,
Berger will be responsible for managing all the investment operations of the
Fund.

         As is the case under the current Investment Advisory Agreement, Berger
will be permitted under the proposed Investment Advisory Agreement to engage a
sub-adviser in furtherance of its duties and responsibilities under the
Investment Advisory Agreement, subject to approval of the Trustees. Berger will
engage BIAM to be responsible for day-to-day investment management
responsibilities under the Sub-Advisory Agreement.

         BIAM's responsibilities under the proposed Sub-Advisory Agreement are
in substance the same as they are under the current Sub-Advisory Agreement. BIAM
is and will continue to be responsible for day-to-day investment management of
the Fund's portfolio.

         Fees. The investment advisory fee borne or paid by the Fund under the
new Investment Advisory Agreement will be lower than that currently borne by the
Fund. Currently, BBOI is paid an investment advisory fee of 0.90% of the average
daily net assets of the Fund. Under the new Investment Advisory Agreement,
Berger will be paid an investment advisory fee at the annual rate of 0.85% of
the first $500 million of average daily net assets, 0.80% of the next $500
million, and 0.75% of all amounts in excess of $1 billion.

         The sub-advisory fee paid by the adviser to the sub-adviser will also
be lowered. Currently, BBOI is obligated to pay BIAM, before waiver, a
sub-advisory fee at an annual rate of 0.45% of average daily net assets. Under
the new Sub-Advisory Agreement, Berger will pay BIAM a sub-advisory fee at the
annual rate of 0.45% of the first $50 million of average daily net assets, 0.40%
of the next $50 million, and 0.30% of all amounts in excess of $100 million. The
Fund is not currently responsible for paying BIAM's sub-advisory fee, and it
will not be responsible for paying BIAM's sub-advisory fee under the new
Sub-Advisory Agreement either.

         Liability Limitation. Under the liability limitation provisions of the
new Agreements, neither Berger nor BIAM will be liable for losses as the result
of any error of judgment or mistake of law in performing its services, except
for willful misfeasance, bad faith or gross negligence in the performance of its
duties, or by reason of reckless disregard of its obligations and duties under
the Agreements and except to the extent otherwise provided by law. This is the
same as the liability limitation provision that appears in the current
Investment Advisory and Sub-Advisory Agreements. In addition, the new Investment
Advisory Agreement with Berger eliminates all indemnity provisions contained in
the current Investment Advisory Agreement, consistent with the advisory
agreements for the other Berger Funds. Further, the liability limitations and
indemnifications in the Sub-Advisory Agreement between Berger and BIAM are
proposed to remain the same as those in the current Sub-Advisory Agreement,
except that a provision will be added to limit Berger's liability to BIAM in the
same manner as BIAM's liability is limited to Berger and the Trust.

         Term. The current Investment Advisory and Sub-Advisory Agreements are
dated May 1, 1997, and were last submitted to a vote and approved by the initial
shareholder at the inception of the Fund on May 1, 1997. Continuation of the
current Agreements was last approved on April 15, 1999.

         If approved by shareholders, the new Agreements will be implemented and
remain in effect until April 2002, and will thereafter continue for successive
one-year periods if continuation is specifically approved at least annually by
the Trustees, or by the vote of a "majority of the outstanding voting
securities" of the Fund as defined under the 1940




                                       7
<PAGE>   12

Act and, in either case, by a majority of the Independent Trustees of the Trust
by votes cast in person at a meeting called for that purpose.

         Termination. The new Agreements may be terminated at any time, without
penalty, by vote of the Trustees or by the vote of "a majority of the
outstanding voting securities" on 60 days' written notice. The Sub-Advisory
Agreement may also be terminated by Berger or by BIAM: (i) upon a material
breach without cure of certain covenants contained in the agreement between
Berger and BIAM relating to the dissolution of BBOI; (ii) upon a material breach
of the Sub-Advisory Agreement; or (iii) after the expiration of 5 years from the
date of the Sub-Advisory Agreement, upon 60 days' advance written notice. The
Agreements will terminate automatically in the event of an "assignment" (as
defined under the 1940 Act).

         Forms of the proposed new Agreements are attached to this Proxy
Statement as Appendix A and Appendix B and should be referred to for details.

         In September 1999, Mr. Thompson received an interest in Berger as part
of his compensation as an executive officer of Berger.

SECTION 15(f) OF THE INVESTMENT COMPANY ACT OF 1940

         As part of the dissolution of BBOI, Berger and BIAM will receive agreed
upon distributions from BBOI, and Berger and BBOI will forego receipt of certain
amounts from BIAM that BIAM would otherwise owe as a joint venturer in BBOI. As
a result, Section 15(f) of the 1940 Act may be considered to apply to the
dissolution. That section generally provides that Berger, BIAM or BBOI may
receive benefits in connection with the sale of an interest in BBOI resulting in
an "assignment" (transfer) of the current Investment Advisory Agreement or
Sub-Advisory Agreement if:

o        for three years following the transaction, at least 75% of the Trustees
         of the Fund are Independent Trustees, and

o        no "unfair burden" (as defined in the 1940 Act) is imposed on the Fund
         as a result of the transaction or any express or implied terms,
         conditions or understandings applicable to the transaction.

         Currently, more than 75% of the Trustees of the Trust are Independent
Trustees. In addition, for a period of three years following the dissolution of
BBOI, Berger has agreed to use its best efforts to assure that at least 75% of
the Trustees of the Fund are Independent Trustees. Further, Berger and BIAM
represented to the Trust that they have no express or implied understanding,
arrangement or intention to impose an "unfair burden" on the Fund and have
agreed to use their respective best efforts to assure compliance with Section
15(f).

================================================================================

                         MEETING AND VOTING INFORMATION

================================================================================

TWO-TIER FUND STRUCTURE; INDIRECT VOTE

         Shares of the Fund are not offered directly to the public, but are sold
only in connection with Variable Contracts issued by Participating Insurance
Companies. As a result, the separate accounts of the Participating Insurance
Companies, rather than individual Contract Owners, are the shareholders of the
Fund entitled to vote on the Proposals.

         However, each Participating Insurance Company will vote such shares in
the manner that is required by law and interpretations thereof, as amended or
changed from time to time. Under current law, a Participating Insurance Company
is required to request voting instructions from Contract Owners and must vote
Fund shares held by each of its separate accounts in proportion to the voting
instructions received. If you complete and sign the voting instruction card, the
shares attributable to your Variable Contract will be voted exactly as you
instruct. If you simply sign and return the voting instruction card, the shares
will be voted in accordance with the Trustees' recommendations. If you do not
return a voting instruction card at all, the shares will be voted in the same
proportion as shares for which instructions have been received from other
Contract Owners of your Participating Insurance Company.

VOTE NEEDED TO ADOPT PROPOSALS

         Approval of each Proposal for the Fund requires the affirmative vote of
a "majority of the outstanding voting securities" of the Fund, within the
meaning of the 1940 Act. The term "majority of the outstanding voting
securities"



                                       10
<PAGE>   15
is defined under the 1940 Act to mean (a) 67% or more of the outstanding shares
present at a meeting of shareholders of the Fund, where the holders of more than
50% of the outstanding shares are present or represented by proxy, or (b) more
than 50% of the outstanding shares of the Fund, whichever is less.

SOLICITATION OF PROXIES

         Solicitation of proxies or voting instructions from Contract Owners
will be made primarily by mail, but may also be made by telephone, facsimile or
personal interview conducted by certain officers or employees of the Trust, BBOI
or their affiliates or representatives. The cost of preparing and mailing the
Notice of Special Meeting of Shareholders, the proxy, this Proxy Statement and
any additional proxy material will be borne by BBOI or its affiliates and not by
the Fund or the Trust.

         A proxy solicitation firm has been engaged to solicit proxies or voting
instructions from Contract Owners. The expenses associated with engaging a proxy
solicitation firm cannot be reasonably estimated at this time. If such expenses
are incurred, they will be borne by BBOI or its affiliates. Participating
Insurance Companies may be reimbursed by BBOI or its affiliates for the
reasonable expenses in forwarding proxy materials to their Contract Owners.

         If a Contract Owner wishes to participate in the meeting and any
adjournments of the meeting, the Contract Owner may submit the voting
instruction card included with this Proxy Statement or attend the meeting in
person. An executed and returned voting instruction card may nevertheless be
revoked by a Contract Owner at any time before it is voted at the meeting by
sending written notice of the revocation to the Trust or by appearing personally
and giving instructions at the meeting.

QUORUM AND VOTING

         Under the Trust Instrument of the Trust, the presence in person or by
proxy of one-third of the outstanding shares of the Fund entitled to vote shall
constitute a quorum for the transaction of business at the meeting. If a quorum
is not present (in person or by proxy) at the time any session of the meeting is
called to order, the persons named as proxies on the proxy card may vote those
proxies which have been received to adjourn the meeting to a later date.

         As of the Record Date, the sole shareholders of the Fund were
Participating Insurance Companies. Since Participating Insurance Companies are
the legal owners of all outstanding shares, attendance by the Participating
Insurance Companies at the meeting will constitute a quorum under the Trust's
Trust Instrument.

         Whether or not a quorum is present, if sufficient votes in favor of the
Proposals or any other proposal presented at the meeting have not been received,
the persons named as proxies may propose one or more adjournments of the meeting
to permit further solicitation of proxies with respect to a proposal. All such
adjournments will require the affirmative vote of a majority of the shares
present in person or by proxy at the session of the meeting to be adjourned. A
vote may be taken on one or more proposals presented at the meeting prior to any
such adjournment if sufficient votes for its approval have been received.

         In tallying shareholder votes, abstentions will be counted for purposes
of determining whether a quorum is present for purposes of convening the
meeting. As mentioned above, each of the Proposals must be approved by the Fund
by (a) a percentage of voting securities present at the meeting, or (b) a
majority of the shares issued and outstanding. Abstentions will be considered to
be both present and issued and outstanding and, as a result, will have the
effect of being counted as votes against a Proposal.

         If any other proposal is presented at the meeting that must be approved
by a percentage of "shares voted" on the proposal, abstentions and broker
non-votes will not be counted as "shares voted" and therefore will have no
effect on the result of the vote.



                                       11

         If the accompanying form of voting instruction card is properly
executed and returned in time to be voted at the meeting, the shares covered
thereby will be voted in accordance with the instructions marked thereon by the
Contract Owner. In the event that the Contract Owner signs and returns the card,
but does not indicate a choice as to a Proposal on the card, the shares covered
thereby will be voted in accordance with the Trustees' recommendation, which is
to vote in favor of the Proposals set forth in the Notice of Special Meeting of
Shareholders, and will be voted in the discretion of the Participating Insurance
Company with regard to any other proposal presented at the meeting. In turn,
shares represented by proxies signed by the Participating Insurance Companies
will be voted similarly at the meeting by the persons named as proxies therein.

PRINCIPAL HOLDERS OF VOTING SECURITIES

         As of the Record Date, the Trustees and officers of the Trust owned as

         Any shareholder with ownership of 25% or more of the Fund's outstanding
securities may be deemed to control it. However, the Participating Insurance
Companies will exercise voting rights attributable to the shares held by them in
accordance with voting instructions received from owners of the contracts issued
by them. To this extent, the Participating Insurance Companies will not exercise
control over the Trust or the Fund by virtue of the voting rights arising from
their record ownership of Fund shares.

         As of the Record Date, no Contract Owners were known to the Trust to be
the indirect beneficial owners of more than 5% of the shares of the Fund except
that the shares owned of record by Conseco Variable Insurance Company include
shares attributable to a Variable Contract owned by Berger, which constitute
approximately 44% of the outstanding shares of the Fund. Berger acquired its
contract in order to provide the initial capital to establish the Fund. Because
the shares attributable to Berger's contract exceed 25% of the outstanding
shares of the Fund, Berger may be deemed to control the Fund. However, Berger
has advised the Trust that it intends to instruct Conseco to vote the shares
attributable to its Variable Contract in the same proportion as shares for which
instructions have been received from other Contract Owners. To that extent,
Berger will not exercise control over the vote on the Proposals by virtue of its
Variable Contract ownership.

OTHER BUSINESS

         While the meeting is called to act upon any other business that may
properly come before it, at the date of this Proxy Statement the only business
which the management of the Fund intends to present or knows that others will

present are the Proposals mentioned in the Notice of Special Meeting of
Shareholders. If any other matters lawfully come before the meeting, and in all
procedural matters at the meeting, proxies which do not contain specific
restrictions to the contrary will be voted on such matters in the discretion of
the persons named as proxies therein, or their substitutes, present and acting
at the meeting.

PROPOSALS OF SHAREHOLDERS

         The Fund need not hold annual shareholder meetings, except as required
by the 1940 Act, applicable state law or the Trust Instrument. Therefore, it is
not presently anticipated that the Fund will hold regular meetings of
shareholders in subsequent years. Accordingly, no anticipated date of the next
meeting can be provided nor a deadline established for the submittal of future
proposals from shareholders.

IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY. WHETHER OR NOT YOU EXPECT TO
ATTEND THE MEETING, PLEASE SIGN THE VOTING INSTRUCTION CARD PROMPTLY AND RETURN
IT IN THE ENCLOSED ENVELOPE TO AVOID UNNECESSARY EXPENSE AND DELAY. NO POSTAGE
IS NECESSARY.

                  as a regulated investment company or as required to maintain
                  compliance with any diversification provisions applicable to
                  insurance company separate accounts or qualified plans
                  investing in the Fund;

         (b)      To cause its officers to attend meetings and furnish oral or

                  fully informed as to the condition of the investment portfolio
                  of the Fund, the investment decisions of Berger, and the
                  investment considerations which have given rise to those
                  decisions;

         (c)      To place orders for the purchase and sale of securities for
                  investments of the Fund and for other related transactions,
                  or, in the event a sub-adviser is engaged pursuant to the
                  authority granted in this Agreement, to supervise the purchase
                  and sale of securities for investments of the Fund and for
                  other related transactions as directed by any such
                  sub-adviser; to give instructions to the custodian (including
                  any subcustodian) of the Fund as to deliveries of securities
                  to and from such custodian and receipt and payments of cash
                  for the account of the Fund, and advise the Trust on the same
                  day such instructions are given; and to submit such reports
                  relating to the valuation of the Fund's assets and to
                  otherwise assist in the calculation of the net asset value of
                  shares of the Fund as may reasonably be requested; on behalf
                  of the Fund, to exercise such voting rights, subscription
                  rights, rights to consent to corporate action and any other
                  rights pertaining to the Fund's assets that may be exercised,
                  in accordance with any policy pertaining to the same that may
                  be adopted or agreed to by the Trustees of the Trust, or, in
                  the event that the Trust retains the right to exercise such
                  voting and other rights, to furnish the Trust with advice as
                  to the manner in which such rights should be exercised;

         (d)      To maintain all books and records required to be maintained by
                  Berger pursuant to the 1940 Act and the rules and regulations
                  promulgated thereunder, as the same may be amended from time
                  to time, with respect to transactions on behalf of the Fund,
                  and



                                       15
<PAGE>   20

                  to furnish the Trustees with such periodic and special reports
                  as the Trustees reasonably may request. Berger agrees that all
                  records which it maintains for the Fund or the Trust are the
                  property of the Trust, agrees to permit the reasonable
                  inspection thereof by the Trust or its designees and agrees to
                  preserve for the periods prescribed under the 1940 Act any
                  records which it maintains for the Trust and which are
                  required to be maintained under the 1940 Act, and further
                  agrees to surrender promptly to the Trust or its designees any
                  records which it maintains for the Trust upon request by the
                  Trust; and

         (e)      At such times as shall be reasonably requested by the
                  Trustees, to provide the Trustees with economic, operational
                  and investment data and reports, including without limitation
                  all information and materials reasonably requested by or
                  requested to be delivered to the Trustees of the Trust
                  pursuant to Section 15(c) of the 1940 Act, and make available
                  to the Trustees any economic, statistical and investment
                  services normally available to similar investment company
                  clients of Berger.

         3. Further Obligations. In all matters relating to the performance of
this Agreement, Berger shall act in conformity with the Trust's Trust
Instrument, bylaws and currently effective registration statements under the
1940 Act and the 1933 Act and any amendments or supplements thereto (the
"Registration Statements") and with the written policies, procedures and
guidelines of the Fund, and written instructions and directions of the Trustees
of the Trust, and shall comply with the requirements of the 1940 Act, the
Advisers Act, the rules thereunder, and all other applicable federal and state
laws and regulations. The Trust agrees to provide Berger with copies of the
Trust's Trust Instrument, bylaws, Registration Statements, written policies,
procedures and guidelines, and written instructions and directions of the
Trustees, and any amendments or supplements to any of them at, or, if
practicable, before the time such materials become effective. Berger shall
maintain errors and omissions insurance in an amount at least equal to that
disclosed to the Trustees in connection with their approval of this Agreement.

         4. Sub-Advisers. Berger may engage one or more sub-advisers in
furtherance of Berger's duties and responsibilities under this Agreement,
subject to the approval of the Trustees of the Trust and, if required by law,
the shareholders of the Fund, pursuant in each case to a written agreement with
a party that, if applicable, meets the requirements of Section 15 of the 1940
Act and the rules thereunder applicable to contracts for service as an
investment adviser of a registered investment company, subject, however, to such
exemptions as may be granted by the Securities and Exchange Commission. The
engagement of one or more sub-advisers pursuant to this provision shall not
diminish or relieve in any way the liability of Berger for any of its duties and
responsibilities under this Agreement. Berger shall appropriately oversee,
monitor and evaluate the activities of any sub-adviser engaged hereunder.



                                       16
<PAGE>   21

         5. Obligations of Trust. The Trust shall have the following obligations
under this Agreement:

         (a)      To keep Berger continuously and fully informed as to the
                  composition of the investment portfolio of the Fund and the
                  nature of all of the Fund's assets and liabilities from time
                  to time;

         (b)      To furnish Berger with a certified copy of any financial
                  statement or report prepared for the Fund by certified or
                  independent public accountants and with copies of any
                  financial statements or reports made to the Fund's
                  shareholders or to any governmental body or securities
                  exchange;

         (c)      To furnish Berger with any further materials or information
                  which Berger may reasonably request to enable it to perform
                  its function under this Agreement; and

         (d)      To compensate Berger for its services in accordance with the
                  provisions of Section 6 hereof.

         6. Compensation. The Trust shall pay to Berger for its services under
this Agreement a fee, payable in United States dollars, at an annual rate of
0.85% of the first $500 million of average daily net assets of the Fund, 0.80%
of the next $500 million of average daily net assets of the Fund, and 0.75% of
any part of the average daily net assets of the Fund in excess of $1 billion.
This fee shall be computed and accrued daily and payable monthly as of the last
day of each month during which or part of which this Agreement is in effect. For
the month during which this Agreement becomes effective and the month during
which it terminates, however, there shall be an appropriate proration of the fee
payable for such month based on the number of calendar days of such month during
which this Agreement is effective.

         7. Expenses.

         (a) Expenses Paid by the Trust. The Trust assumes and shall pay all
expenses incidental to its operations and business not specifically assumed or
agreed to be paid by Berger hereunder or otherwise, including, but not limited
to, any compensation, fees or reimbursements which the Trust pays to its
Trustees who are not interested persons of Berger; compensation of the Fund's
custodian, transfer agent, registrar and dividend disbursing agent and other
service providers; legal, accounting, audit and printing expenses;
administrative, clerical, recordkeeping and bookkeeping expenses; brokerage
commissions and all other expenses in connection with execution of portfolio
transactions (including any appropriate commissions paid to Berger or its
affiliates for effecting exchange listed, over-the-counter or other securities
transactions); interest; all federal, state and local taxes (including stamp,
excise, income and franchise taxes); costs of stock certificates and expenses of
delivering such certificates to the purchasers thereof; expenses of local
representation in Delaware; expenses of shareholders' meetings and of preparing,
printing and distributing proxy statements, notices, and reports to
shareholders; expenses of preparing and filing reports and tax returns with
federal and state regulatory authorities; all expenses incurred in complying
with all federal and state laws and the laws




                                       17
<PAGE>   22

of any foreign country applicable to the issue, offer or sale of shares of the
Fund, including, but not limited to, all costs involved in preparing, printing
and mailing prospectuses and statements of additional information to
shareholders of the Fund; and all fees, dues and other expenses incurred by the
Trust in connection with the membership of the Trust in any trade association or
other investment company organization. To the extent that Berger shall perform
any of the above described administrative and clerical functions, including
transfer agency, registry, dividend disbursing, recordkeeping, bookkeeping,
accounting and blue sky monitoring and registration functions, and the
preparation of reports and returns, the Trust shall pay to Berger compensation
for, or reimburse Berger for its expenses incurred in connection with, such
services as Berger and the Trust shall agree from time to time, any other
provision of this Agreement notwithstanding.

         (b) Expenses Paid by Berger. Berger shall pay all its own costs and
expenses incurred in fulfilling its obligations under this Agreement. In
addition to such costs and expenses, Berger shall incur and pay the following
expenses relating to the Fund's operations:

             (i) Reasonable compensation, fees and related expenses of the
Trust's officers and Trustees, except for such Trustees who are not interested
persons of Berger;

             (ii) Rental of offices of the Trust; and

             (iii) Fees of any sub-adviser engaged by Berger pursuant to the
authority granted in Section 4 hereof.

         8. Brokerage Commissions. For purposes of this Agreement, brokerage
commissions paid by the Fund upon the purchase or sale of its portfolio
securities shall be considered a cost of securities of the Fund and shall be
paid by the Fund. Absent instructions from the Trust to the contrary, Berger is
authorized and directed to place portfolio transactions for the Fund only with
brokers and dealers who render satisfactory service in the execution of orders
at the most favorable prices and at reasonable commission rates, provided,
however, that Berger may pay a broker an amount of commission for effecting a
securities transaction in excess of the amount of commission another broker
would have charged for effecting that transaction if Berger determines in good
faith that such amount of commission was reasonable in relation to the value of
the brokerage and research services provided by such broker viewed in terms of
either that particular transaction or the overall responsibilities of Berger.
Berger is also authorized to consider sales of variable insurance contracts that
permit allocation of contract values to the Fund as a factor in selecting
broker-dealers to execute portfolio transactions for the Fund. In placing
portfolio business with such broker-dealers, Berger shall seek the best
execution of each transaction. Subject to the terms of this Agreement and the
applicable requirements and provisions of the law, including the 1940 Act and
the Securities Exchange Act of 1934, as amended, and in the event that Berger or
an affiliate is registered as a broker-dealer, Berger may select a broker with
which it or any of its affiliates or the Fund is affiliated. Berger or such
affiliated broker may effect or execute Fund securities transactions, whether on
a securities exchange or in the over-the-counter market, and receive separate




                                       18
<PAGE>   23

compensation from the Fund therefor. Notwithstanding the foregoing, the Trust
shall retain the right to direct the placement of all portfolio transactions,
and the Trustees of the Trust may establish policies or guidelines to be
followed by Berger in placing portfolio transactions for the Trust pursuant to
the foregoing provisions. Berger shall report on the placement of portfolio
transactions in the prior fiscal quarter at each quarterly meeting of such
Trustees. To the extent consistent with applicable law, purchase or sell orders
for the Fund may be aggregated with simultaneous purchase or sell orders for
other clients of Berger. Whenever Berger simultaneously places orders to
purchase or sell the same security on behalf of the Fund and one or more other
clients of Berger, such orders will be allocated as to price and amount among
all such clients in a manner reasonably believed by Berger to be fair and
equitable to each client. The Trust recognizes that in some cases, this
procedure may adversely affect the results obtained for the Fund.

         9. Termination. This Agreement may be terminated at any time, without
penalty, by the Trustees of the Trust, or by the shareholders of the Fund acting
by vote of at least a majority of its outstanding voting securities, provided in
either case that sixty (60) days' advance written notice of termination be given
to Berger at its principal place of business. This Agreement may be terminated
by Berger at any time, without penalty, by giving sixty (60) days' advance
written notice of termination to the Trust, addressed to its principal place of
business. The Trust agrees that, consistent with the terms of the Trust's Trust
Instrument, the Trust shall cease to use the name "Berger" in connection with
the Fund as soon as reasonably practicable following any termination of this
Agreement if Berger does not continue to provide investment advice to the Fund
after such termination.

         10. Assignment. This Agreement shall terminate automatically in the
event of any assignment of this Agreement.

         11. Term. This Agreement shall continue in effect until April 30, 2002,
unless sooner terminated in accordance with its terms, and shall continue in
effect from year to year thereafter only so long as such continuance is
specifically approved at least annually by the vote of a majority of the
Trustees of the Trust who are not parties hereto or interested persons of any
such party, cast in person at a meeting called for the purpose of voting on the
approval of the terms of such renewal, and by either the Trustees of the Trust
or the affirmative vote of a majority of the outstanding voting securities of
the Fund.

         12. Amendments. This Agreement may be amended by the parties only if
such amendment is specifically approved (i) by a majority of the Trustees,
including a majority of the Trustees who are not interested persons of the Fund
or Berger and, (ii) if required by applicable law, by the affirmative vote of a
majority of the outstanding voting securities of the Fund.

         13. Allocation of Expenses. The Trustees shall determine the basis for
making an appropriate allocation of the Trust's expenses (other than those
directly attributable to the Fund)



                                       19
<PAGE>   24

between the Fund and any other series of the Trust and between the Fund and
other investment companies managed by Berger or its affiliates.

         14. Limitation on Personal Liability. NOTICE IS HEREBY GIVEN that the
Trust is a business trust organized under the Delaware Business Trust Act
pursuant to a Certificate of Trust filed in the office of the Secretary of State
of the State of Delaware. All parties to this Agreement acknowledge and agree
that the Trust is a series trust and all debts, liabilities, obligations and
expenses incurred, contracted for or otherwise existing with respect to a
particular series shall be enforceable against the assets held with respect to
such series only, and not against the assets of the Trust generally or against
the assets held with respect to any other series and further that no Trustee,
officer or holder of shares of beneficial interest of the Trust shall be
personally liable for any of the foregoing.

         15. Limitation of Liability of Berger. Berger shall not be liable for
any error of judgment or mistake of law or for any loss arising out of any
investment or for any act or omission taken with respect to the Fund, except for
willful misfeasance, bad faith or gross negligence in the performance of its

section, "Berger" shall include any affiliate of Berger performing services for
the Trust contemplated hereunder and managers, officers and employees of Berger

employee of Berger to engage in any other business or to devote his or her time
and attention in part to the management or other aspects of any other business,
whether of a similar nature or a dissimilar nature. It is understood that
Trustees, officers and shareholders of the Trust are or may become interested in
Berger as managers, officers and shareholders of Berger, that managers,

interested in the Trust, and that Berger may become interested in the Trust as a
shareholder or otherwise.

         WHEREAS, Berger has entered into an Investment Advisory Agreement (the
"Advisory Agreement") with Berger Institutional Products Trust (the "Trust"), a
Delaware business trust and an open-end management investment company registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), with
respect to Berger IPT - International Fund (the "Fund"), a separate series of
the Trust;

         WHEREAS, BIAM is engaged in the business of rendering investment
advisory services and is registered as an investment adviser under the
Investment Advisers Act of 1940, as amended (the "Advisers Act"); and

         WHEREAS, Berger, with the approval of the Trust, desires to delegate to
BIAM its duties and responsibilities for providing investment advisory services
to the Fund, and BIAM is willing to accept such delegation and to render such
investment advisory services.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged the parties agree as follows:

         1. Duties of BIAM. Berger hereby engages the services of BIAM as
sub-adviser for the Fund in furtherance of the Advisory Agreement. BIAM agrees
to perform the following duties, subject to the oversight of Berger and to the
overall control of the officers and the Trustees of the Trust:

                  (a) BIAM shall manage the investment operations of the Fund
         and the composition of its investment portfolio, and determine without
         prior consultation with Berger or the Trust, what securities and other
         assets of the Fund will be acquired, held, disposed of or loaned in
         conformity with the investment objective, policies and restrictions and
         the other statements concerning the Fund in the Trust's trust
         instrument, as amended from time to time (the "Trust Instrument"), the
         Trust's bylaws ("Bylaws") and the Trust's registration statements under
         the 1940 Act and the Securities Act of 1933, as amended (the "1933
         Act"), the 1940 Act and the Advisers Act, the rules and regulations
         thereunder, and all other applicable federal and state laws and
         regulations, and the provisions of the Internal Revenue Code of 1986,
         as amended, applicable to the Fund as a regulated investment company;

                  (b) BIAM shall cause its officers to attend meetings and
         furnish oral or written reports, as the Trust or Berger may reasonably
         require, in order to keep Berger, the Trustees and



<PAGE>   27

         appropriate officers of the Trust fully informed as to the condition of
         the investment portfolio of the Fund, the investment decisions of BIAM,
         and the investment considerations which have given rise to those
         decisions;

                  (c) BIAM shall maintain all books and records required to be
         maintained by BIAM pursuant to the 1940 Act, the Advisers Act, and the
         rules and regulations promulgated thereunder, as the same may be
         amended from time to time, with respect to transactions on behalf of
         the Fund, and shall furnish the Trustees and Berger with such periodic
         and special reports as the Trustees or Berger reasonably may request.
         BIAM hereby agrees that all records which it maintains for the Fund or
         the Trust are the property of the Trust, agrees to permit the
         reasonable inspection thereof by the Trust or its designees and agrees
         to preserve for the periods prescribed under the 1940 Act and the
         Advisers Act any records which it maintains for the Trust and which are
         required to be maintained under the 1940 Act and the Advisers Act, and
         further agrees to surrender promptly to the Trust or its designees any
         records which it maintains for the Trust upon request by the Trust;

                  (d) BIAM shall place orders for the purchase and sale of
         securities for investments of the Fund and for other related
         transactions; to give instructions to the custodian (including any
         subcustodian) of the Fund as to deliveries of securities to and from
         such custodian and receipt and payments of cash for the account of the
         Fund, and advise the Trust on the same day such instructions are given;

                  (e) BIAM will provide Berger and the Trust with the current
         reports that show holdings, current prices, income details and
         month-end valuations, and shall communicate with the custodian and
         Berger on valuation issues concerning the Fund's securities;

                  (f) BIAM shall, on behalf of the Fund, exercise such voting
         rights, subscription rights, rights to consent to corporate action and
         any other rights pertaining to the Fund's assets that may be exercised,
         in accordance with any policy pertaining to the same that may be
         adopted or agreed to by the Trustees of the Trust, or, in the event
         that the Trust retains the right to exercise such voting and other
         rights, to furnish the Trust with advice as may be reasonably requested
         as to the manner in which such rights should be exercised;

                  (g) At such times as shall be reasonably requested by the
         Trustees or Berger, BIAM shall provide the Trustees and Berger with
         economic, operational and investment data and reports, including
         without limitation all information and materials reasonably requested
         by or requested to be delivered to the Trustees of the Trust pursuant
         to Section 15(c) of the 1940 Act, and shall make available to the
         Trustees and Berger any economic, statistical and investment services
         normally available to similar investment company clients of BIAM; and

                  (h) BIAM will provide to Berger for regulatory filings and
         other appropriate uses pertaining to the activities of BIAM relating to
         the Fund or the Trust materially accurate and complete information
         relating to BIAM as may reasonably be requested by Berger from time to
         time.


<PAGE>   28
         2. Further Obligations. In all matters relating to the performance of
this Agreement, BIAM shall act in conformity with the Trust Instrument, Bylaws
and currently effective registration statement under the 1940 Act and the 1933
Act and any amendments or supplements thereto (the "Registration Statements")
and with the written policies, procedures and guidelines of the Fund, written
instructions and directions of the Trustees based on resolutions duly adopted by
the Trustees, and written instructions and directions of Berger, officers of the
Trust, as may be communicated to it by Berger and shall comply with the
requirements of the 1940 Act, the Advisers Act, the rules thereunder, and all
other applicable federal and state laws and regulations. Berger agrees to
provide to BIAM copies of the Trust Instrument, Bylaws, Registration Statement,
written policies, procedures, and guidelines, written instructions of the
Trustees based on resolutions duly adopted by the Trustees, and written
instructions from Berger, officers of the Trust, and any amendments or
supplements to any of them at, or, if practicable, before the time such
materials become adopted. BIAM shall not be required to follow any amendments or
supplements to any such policies, procedures, guidelines or written instructions
until BIAM has received such amendment or supplement in writing. BIAM may
perform its services through any qualified employee, officer or agent of BIAM,
and Berger and the Trust shall not be entitled to the efforts, advice,
recommendations or judgment of any specific person.

         3. Obligations of Berger. Berger shall have the following obligations
under this Agreement:

                  (a) To keep BIAM continuously and fully informed (or cause the
         custodian of the Fund's assets to keep BIAM so informed) as to the
         composition of the investment portfolio of the Fund, cash requirements
         and cash available for investment in the Fund and the nature of all of
         the Fund's assets and liabilities;

                  (b) To furnish BIAM with a certified copy of any financial
         statement or report prepared for the Fund by certified or independent
         public accountants and with copies of any financial statements or
         reports made to the Fund's investors or to any governmental body or
         securities exchange;

                  (c) To furnish BIAM with any further materials or information
         which BIAM may reasonably request to enable it to perform its function
         under this Agreement;

                  (d) To compensate BIAM for its services in accordance with the
         provisions of Section 4 hereof.

         4. Compensation. Berger shall pay to BIAM for its services under this
Agreement a fee, payable in United States dollars, in accordance with the
Schedule in Exhibit A hereto. This fee shall be computed and accrued daily and
payable monthly on the last day of each month during which or part of which this
Agreement is in effect. BIAM reserves the right to waive or reimburse all or any
portion of its fees hereunder.

         5. Expenses and Excluded Expenses. BIAM shall pay all its own costs and
expenses incurred in rendering the services required under this Agreement.


<PAGE>   29
         6. Brokerage Commissions. For purposes of this Agreement, brokerage
commissions paid by the Fund upon the purchase or sale of its portfolio
securities shall be considered a cost of securities of the Fund and shall be
paid by the Fund. Absent instructions from Berger or the Trust to the contrary,
BIAM shall place all orders for the purchase and sale of securities for the Fund
with brokers and dealers selected by BIAM in the exercise of its fiduciary duty
to obtain best execution. BIAM is authorized and directed to place portfolio
transactions for the Fund only with brokers and dealers who BIAM believes will
render satisfactory service in the execution of orders at the best overall terms
available; provided, however, that BIAM may pay a broker an amount of commission
for effecting a securities transaction in excess of the amount of commission
another broker would have charged for effecting that transaction if BIAM
determines in good faith that such amount of commission was reasonable in
relation to the value of the brokerage and research services provided by such
broker viewed in terms of either that particular transaction or the overall
responsibilities of BIAM. BIAM is also authorized, consistent with the
requirements of NASD Conduct Rule 2830(k), to consider sales of variable
insurance contracts that permit allocation of contract values to the Fund as a
factor in selecting broker-dealers to execute portfolio transactions for the
Fund. In placing portfolio business with such broker-dealers, BIAM shall seek
the best execution of each transaction. Subject to the terms of this Agreement
and the applicable requirements and provisions of the law, including the 1940
Act and the Securities Exchange Act of 1934, as amended, and in the event that
BIAM or an affiliate is registered as a broker-dealer, BIAM may select a broker
with which it or any of its affiliates or the Fund is affiliated. BIAM or such
affiliated broker may effect or execute Fund securities transactions on an
agency basis, whether on a securities exchange or in the over-the-counter
market, and receive compensation from the Fund therefor.

         Notwithstanding the foregoing, the Trust shall retain the right to
direct the placement of all portfolio transactions, and Berger or the Trustees
may establish policies or guidelines to be followed by BIAM in placing portfolio
transactions for the Fund pursuant to the foregoing provisions. BIAM shall
report on the placement of portfolio transactions in the prior fiscal quarter at
each quarterly meeting of the Trustees. To the extent consistent with applicable
law, purchase or sell orders for the Fund may be aggregated with simultaneous
purchase or sell orders for other clients of BIAM. Whenever BIAM simultaneously
places orders to purchase or sell the same security on behalf of the Fund and
one or more other clients of BIAM, such orders will be allocated as to price and
amount among all such clients in a manner reasonably believed by BIAM to be fair
and equitable to each client. Berger and the Trust recognize that, in some
cases, this procedure may adversely affect the results obtained for the Fund.

         7. Representations of BIAM. BIAM hereby represents, warrants and
covenants to Berger as follows:

                  (a) BIAM: (i) is registered as an investment adviser under the

         company pursuant to Section 9(a) of the 1940 Act or otherwise, and of
         the institution of any administrative, regulatory or judicial
         proceeding against BIAM that could have a material adverse effect upon
         BIAM's ability to fulfill its obligations under this Agreement.

                  (b) BIAM has adopted a written code of ethics complying with
         the requirements of Rule 17j-1 under the 1940 Act and will provide

         its adoption. Within 45 days after the end of the last calendar quarter
         of each year that this Agreement is in effect, the president or a vice
         president of BIAM shall certify to Berger that BIAM has complied with

         violation. Upon the written request of Berger, BIAM shall permit
         Berger, its employees or its agents to examine the reports required to
         be made to BIAM by Rule 17j-1.

                  (c) BIAM has provided Berger with a copy of its Form ADV as
         most recently filed with the U.S. Securities and Exchange Commission
         ("SEC") and will, promptly after filing any material amendment to its
         Form ADV with the SEC, furnish a copy of such amendment to Berger.

                  (d) BIAM will notify Berger of any change in the identity or
         control of its shareholders owning a 10% or greater interest in BIAM,
         or any change that would constitute a change in control of BIAM under
         the 1940 Act, prior to any such change if BIAM is aware, or should be
         aware, of any such change, but in either event as soon as any such
         change becomes known to BIAM, so long as such prior notification would
         not violate applicable law. In such event, BIAM shall notify Berger
         upon the occurrence of such change of control.

         8. Representations of Berger. Berger hereby represents, warrants and
covenants to BIAM as follows:

                  (a) Berger: (i) is registered as an investment adviser under
         the Advisers Act and will continue to be so registered for so long as
         this Agreement remains in effect; (ii) is not prohibited by the 1940
         Act or the Advisers Act from fulfilling its obligations under this
         Agreement; (iii) has met in all material respects, and will continue to
         meet in all material respects for so long as this Agreement remains in
         effect, any other applicable federal or state requirements, or the
         applicable requirements of any regulatory or industry self-regulatory
         organization necessary to be met in order to fulfill its obligations
         under this Agreement; (iv) has the legal and corporate authority to
         enter into and perform this Agreement; and (v) will immediately notify
         BIAM of the occurrence of any event that would disqualify Berger from
         serving as an investment adviser of an investment company pursuant to
         Section 9(a) of the 1940 Act or otherwise, and of the institution of
         any administrative, regulatory or judicial proceeding against Berger
         that could have a material adverse effect upon Berger' ability to
         fulfill its obligations under this Agreement.


<PAGE>   31

                  (b) Berger has adopted a written code of ethics complying with
         the requirements of Rule 17j-1 under the 1940 Act and will provide BIAM
         with a copy of such code of ethics, together with evidence of its
         adoption.

                  (c) Berger has provided BIAM with a copy of its Form ADV as
         most recently filed with the U.S. Securities and Exchange Commission
         ("SEC") and will, promptly after filing any material amendment to its
         Form ADV with the SEC, furnish a copy of such amendment to BIAM.

                  (d) Berger will notify BIAM of any change in the identity or
         control of its shareholders owning a 10% or greater interest in Berger,
         or any change that would constitute a change in control of Berger under
         the 1940 Act, prior to any such change if Berger is aware, or should be
         aware, of any such change, but in either event as soon as any such
         change becomes known to Berger, so long as such prior notification
         would not violate applicable law. In such event, Berger shall notify
         BIAM upon the occurrence of such change of control.

         9. Term. This Agreement shall become effective as of the date first set
forth above and shall continue in effect until the date before the second
anniversary of this Agreement, unless sooner terminated in accordance with its
terms, and shall continue in effect from year to year thereafter only so long as
such continuance is specifically approved at least annually by the vote of a
majority of the Trustees who are not parties hereto or interested persons of the
Trust or Berger, cast in person at a meeting called for the purpose of voting on
the approval of the terms of such renewal, and by either the Trustees or the
affirmative vote of a majority of the outstanding voting securities of the Fund.

         10. Termination. This Agreement may be terminated: (i) at any time,
without penalty, by the Trustees, or by the holders of interests in the Fund
acting by vote of at least a majority of its outstanding voting securities,
provided in any such case that 60 days' advance written notice of termination be
given to BIAM at its principal place of business; (ii) at any time, without
penalty, by the Trust if BIAM becomes unable to discharge its duties and
obligations under this Agreement; (iii) by BIAM or Berger upon a material breach
by the other party hereto of any of the covenants in Section 8 of that certain

breach shall not have been cured within a 30 day period after notice of such
breach; (iv) by BIAM or Berger upon a material breach by the other party hereto
of any of the terms of this Agreement, if such breach shall not have been cured
within a 30 day period after notice of such breach; or (v) by BIAM or Berger at
any time after the expiration of five (5) years from the date of this Agreement,
without penalty, by giving 60 days' advance written notice of termination to the
other party hereto and to the Trust.

         11. Assignment and Amendments. This Agreement shall automatically
terminate in the event of its assignment. This Agreement may be amended by the
