               FIRST ALLMERICA FINANCIAL LIFE INSURANCE COMPANY


Dear Contract Owner:

The Palladian Trust (the "Trust") will hold a special meeting of shareholders on
June 8, 1998.

The attached Notice and Statement Concerning the Special Meeting discusses the
five proposals to be considered at the meeting. The Board of Trustees of the
Trust has considered the proposals and determined that the approval of each one
is in the best interest of the contract owners participating in the Trust.

You, as the owner of a variable annuity contract that participates in a separate
account of either Allmerica Financial Life Insurance and Annuity Company or
First Allmerica Financial Life Insurance Company (collectively "Allmerica"), are
entitled to instruct Allmerica how to vote the shares of the Capital Stock of
the Trust related to your interest in the separate account as of the close of
business on April 9, 1998.

You have received a separate voting instruction form for each Palladian Trust
Portfolio in which you hold an interest. The voting instruction form for each
Portfolio lists the proposals to be voted upon by contract owners with an
interest in that Portfolio. Not all Portfolios will vote on every proposal.

Please take a few minutes to consider this matter and then exercise your right
to give your instructions by completing, dating, and signing EVERY enclosed
voting instruction form. Included is a self-addressed and postage-paid envelope
for your convenience. In order to be given effect, your voting instructions must
be received no later than June 2, 1998.

If you have any questions about these materials, please contact Allmerica at 
(800) 917-1909.

This Statement uses the term "persons having voting rights with respect to" a
particular Portfolio to refer to a contract owner who has allocated all or part
of his or her contract fund to be invested in that Portfolio. Each contract
owner is entitled to give instructions on how to vote the number of 
<PAGE>
 
                                       2


shares of each Portfolio related to his or her interests in the Separate
Accounts. Each full share shall have one vote, and each fractional share shall
have a proportionate fractional vote. Votes of abstaining contract owners are
not counted. If a contract owner submits a properly executed voting instruction
form but omits instructions with respect to one or more items or proposals,
Allmerica Financial Life Insurance and Annuity Company and First Allmerica
Financial Life Insurance Company (collectively, "Allmerica") will vote the
appropriate number of Trust shares as if the contract owner had given
instructions to vote for approval of that item or proposal. Allmerica will vote
Portfolio shares held in each subaccount for which it does not receive properly
executed instruction forms in the same proportion as it votes Portfolio shares
held in that subaccount for which it does receive properly executed instruction
forms.

Interactive/Telecomm Portfolios owns the following Portfolio shares:

received from persons having voting rights, which will then be eligible to be
considered for distribution with the proxy materials for the next called meeting
of such persons.

                                PROPOSAL NO. 1

                                  ELECTION OF
                                 NEW TRUSTEES

All person having voting rights with respect to any of the Portfolios will vote
on this proposal.

The business and affairs of the Trust is managed under the direction of the
Board of Trustees (the "Board"), which serves the same function as the Board of
Directors of a corporation. Each Trustee is elected by all persons having voting
rights with respect to the Trust collectively. Currently, the Board has two
Trustees, Matthew J. Stacom (who serves as Chairman) and Tom N. Dallape.

At the recommendation of AFIMS, the Trust's new Manager, the Board has nominated
Gordon Holmes and George J. Sullivan, Jr. also to serve as Trustees.  If and
when shareholders elect Mr. Gordon and/or Mr. Sullivan, Mr. Stacom will retire
and Mr. Sullivan will become Chairman and President of the Trust.

During 1997, the Board of Trustees met four times.  The Board of Trustees does
not currently have an audit, nominating, or compensation committee.  During
1997, the Board had an Audit Committee comprised of the Trustees who were not
interested persons of the Trust or its advisers. That Committee met once in
1997.  Because all current and nominated Trustees are not interested persons of
the Trust or its adviser, the Audit Committee is currently inactive.

The table below sets forth information about the current Trustees, the nominees
to serve as Trustees, and the officers of the Trust:

None of the current Trustees or nominees for Trustee are "interested persons" of
the Trust, as that term is defined in the 1940 Act.  When Palladian Advisors,
Inc. ("PAI") served as an adviser to the Trust, Mr. Stacom was an interested
person of the Trust because he is Chairman of PAI.  Because PAI no longer serves
as an adviser to the Trust, Mr. Stacom is no longer an interested person of the
Trust.

Messrs. Stacom and Dallape do not receive any pension or retirement benefits
from the Trust. Neither  individual receives any additional compensation from
any registered investment companies other than the Trust.

REQUIRED VOTE

The shares of all the Portfolios are voted together to elect Trustees. Each
person nominated for Trustee will be elected if he receives the votes of a
majority of the outstanding shares of the Trust. The Investment Company Act of
1940 (the "1940 Act") defines a majority of outstanding shares of the Trust as
the lesser of (a) a vote of 67% or more of the outstanding Trust shares whose
holders are present or represented by proxy at the meeting if the holders of
more than 50% of all outstanding Trust shares are present in person or
represented by proxy at the meeting, or (b) a vote of more than 50% of all
outstanding Trust shares. If one nominee does not receive the votes of a
majority of outstanding shares, he will not be elected, but that will not affect
the election of the other nominee.

THE BOARD RECOMMENDS THAT YOU VOTE FOR BOTH OF THE NOMINEES TO THE BOARD OF
TRUSTEES.

                                PROPOSAL NO. 2

              APPROVAL OF A NEW MANAGEMENT AGREEMENT UNDER WHICH
           ALLMERICA FINANCIAL INVESTMENT MANAGEMENT SERVICES, INC.
                      WILL SERVE AS MANAGER OF THE TRUST

All person having voting rights with respect to any of the Portfolios will vote
on this proposal.

Allmerica Financial Investment Management Services, Inc. ("AFIMS" or the
"Manager") serves as Manager to the Trust pursuant to a Management Agreement
with the Trust dated February 12, 1998, as amended April 9, 1998 (the
"Management Agreement"). That agreement was initially approved by the Board of
Trustees (the "Board") on February 11, 1998 and minor amendments were approved
by the Board on April 9, 1998.  AFIMS may continue as Manager only until June
11, 1998, unless persons having voting rights approve the Management Agreement.

AFIMS is the successor to another investment adviser affiliated with Allmerica,
Allmerica Investment Management Company, Inc. ("AIMCO").  Prior to April 16,
1998, AIMCO served as an investment adviser to investment companies registered
under the 1940 Act and was also engaged in financial planning for other clients.
As part of a reorganization on April 16, 1998, AIMCO transferred to AFIMS that
portion of its business relating to registered investment companies such as the
Trust, while AIMCO retained its financial planning business.  The same personnel
and procedures previously employed by AIMCO to service the Trust are used by
AFIMS.   Thus, while AIMCO is the signatory to the Management Agreement, AFIMS
has assumed AIMCO's role under that agreement.

This proposal submits the Management Agreement approved by the Board for the
approval of persons having voting rights. If the persons having voting rights
approve the Management Agreement, it will continue in effect through February
11, 2000 and will continue thereafter if the Board approves it annually. The
Management Agreement will terminate on June 11, 1998 with respect to any
Portfolio for which persons having voting rights fail to approve this proposal.

This proposal would not change the Portfolio Managers who have day-to-day
responsibility for the investment decisions for each Portfolio. Regardless
whether persons having voting rights accept or reject this proposal, each
Portfolio will retain its current Portfolio Manager. Information about a change
in Portfolio Manager for the Global Strategic Income Portfolio appears below in
connection with Proposal 4.

BACKGROUND

Prior to February 12, 1998, Palladian Advisors, Inc. ("PAI" or the "former
manager") served as Manager to the Trust pursuant to a management agreement
between PAI and the Trust. PAI is a California corporation located at 701
Palomar Airport Road, Suite 300, Carlsbad, California 92009.
<PAGE>
 
                                       9

PAI had agreed to limit operating expenses and reimburse those expenses to the
extent that each Portfolio's "other expenses" (i.e., expenses other than
management fees) from September 11, 1996 through December 31, 1997 exceed the
following expense limitations (expressed as an annualized percentage of average
daily net assets):  Value Portfolio, 0.70%; Growth Portfolio, 0.70%;
International Growth Portfolio, 1.20%; Global Strategic Income Portfolio, 1.20%;
Global Interactive/Telecomm Portfolio, 1.20%.

At the request of the Board of Trustees, PAI had committed to pay all amounts
due under the expense reimbursement arrangement on or about December 31, 1997.
In January 1998, however, PAI advised the Board of Trustees that it did not have
sufficient assets to make the required payment. Accordingly, the Board of
Trustees and PAI pursued and considered other options under which the payment
could be made. The Board of Trustees determined that it was in the best
interests of shareholders to accept an offer from a group (the "Payment Group")
willing to immediately pay to the Trust the full amount due under the expense
limitation. The Payment Group currently includes Allmerica and certain
principals of PAI or entities selling the variable contracts.

On January 28, 1998, the Payment Group paid the Portfolios the following
amounts, which were the full amounts due under the expense limitation
arrangement:  Value Portfolio, $128,362.72; Growth Portfolio, $114,448.91;
International Growth Portfolio, $89,895.43; Global Strategic Income Portfolio,
$103,436.57; Global Interactive/Telecomm Portfolio, $88,983.02. Accordingly, the
Trust has been fully reimbursed for amounts owed under the expense limitation
arrangement.

Through December 31, 1999, each Portfolio must reimburse the Payment Group for
the payment described above, provided that such reimbursement does not cause the
Portfolio's "other expense" ratio to exceed the previous expense limitation for
that Portfolio under the Manager's expense limitation arrangement. (Those
limitations are listed above.)  This reimbursement obligation is the same as the
reimbursement obligation that was in place for PAI. After December 31, 1999, the
Portfolios' reimbursement liability to the Payment Group will cease.

BOARD APPROVAL OF NEW MANAGEMENT AGREEMENT

In light of the background described above, the Board and PAI requested that
AIMCO (the predecessor to AFIMS) accept the role of Manager of the Trust. The
Board concluded that having the Allmerica-affiliated investment adviser assume
this responsibility was in the best interests of the Trust and its shareholders.
AFIMS (as successor to AIMCO) has substantial experience acting as the overall
manager of a multiple-portfolio mutual fund in which it monitors and oversees
separate subadvisers who are responsible for day-to-day investment decisions.
The Board also considered that the Management Agreement, including the
compensation terms, are substantially the same as the previous management
agreement with PAI. AIMCO agreed to assume the role of Manager.  At a February
11, 1998 meeting, the Board unanimously approved a new Management Agreement with
AIMCO and appointed AIMCO Manager of the Trust as of February 12, 1998. The
Board was subsequently notified of the reorganization by which AIMCO's
responsibilities under the Management Agreement were assumed by AFIMS.  In
accordance with rules of the Securities and 
<PAGE>
 
                                       10

Exchange Commission (the "SEC") the Management Agreement is effective for 120
days to provide time for the Trust to seek shareholder approval. As noted above,
this Proposal seeks shareholder approval of the Management Agreement so that it
may continue in effect past June 11, 1998.

NEW EXPENSE LIMITATION AGREEMENT

Allmerica has voluntarily agreed to limit operating expenses and reimburse those
expenses to the extent that each Portfolio's 1998 "other expenses" (i.e.,
expenses other than management fees) exceed the following expense limitations
(expressed as an annualized percentage of average daily net assets):  Value
Portfolio, 1.00%; Growth Portfolio, 1.00%; International Growth Portfolio,
1.20%; Global Strategic Income Portfolio, 1.20%; Global Interactive/Telecomm
Portfolio, 1.20%. For the three global or international Portfolios, the expense
limitation for 1998 is the same percentage (1.20%) as the 1997 limitation, which
is described in the prospectus. For the Value and Growth Portfolios, the 1998
limitation is 1.00% rather than the 0.70% 1997 limitation. Allmerica has agreed
to pay any amount due for a calendar month not later than the 15th day of the
following calendar month (with any final adjustment to be made not later than
January 15, 1999). Allmerica, if agreed to by the Board, may continue this
voluntary expense limitation past December 31, 1998. This expense limitation was
implemented effective February 13, 1998. In addition, on February 24, 1998,
Allmerica voluntarily contributed to the Portfolios the following amounts as
capital:  Value Portfolio, $8,469.29; Growth Portfolio, $10,350.93;
International Growth Portfolio, $7,723.73; Global Strategic Income Portfolio,
$7,936.72; Global Interactive/Telecomm Portfolio,  $6,618.72. These amounts were
contributed to offset expenses accrued to the Portfolios in excess of the
expense limitations during the period January 1, 1998 through February 12, 1998.
Allmerica received no shares of beneficial interest or other consideration in
exchange for these contributions. These capital contributions resulted in an
increase in paid-in capital for each Portfolio.

For the two years following the date that the Allmerica expense limitation ends,
each Portfolio will reimburse Allmerica for any Portfolio expenses it reimbursed
pursuant to the expense limitation, provided that such reimbursement to
Allmerica does not cause the Portfolio's "other expense" ratio to exceed the
limitation for that Portfolio set forth above. This reimbursement for the 1998
expenses will not commence until the Payment Group has been fully reimbursed for
the 1996 and 1997 expenses, as discussed above. After the two year period after
the Allmerica expense limitation ends, the Portfolios' obligation to reimburse
Allmerica will cease.

INFORMATION ABOUT THE NEW MANAGER

AFIMS, a Massachusetts corporation, is registered with the Securities and
Exchange Commission as an investment adviser. AFIMS is located at 440 Lincoln
Street, Worcester, Massachusetts 01653. AFIMS is wholly-owned subsidiary of SMA
Financial Corp., which in turn is a wholly-owned subsidiary of First Allmerica
Financial Life Insurance Company, a wholly owned subsidiary of Allmerica
Financial Corporation ("AFC"). AFC is the parent company of the two life
insurance companies -- Allmerica Financial Life Insurance Company and Annuity
Company and First Allmerica Financial Life Insurance Company -- that currently
utilize the Trust as an underlying fund 
<PAGE>
 
                                       11


for their variable contracts. FMR Corporation owns or controls over 10% of the
common stock of AFC and therefore may be deemed to have a controlling interest
in AFC. Edward C. Johnson 3d and Abigail P. Johnson each may be deemed a
controlling person of FMR Corporation by virtue of their ownership or control of
stock of that entity.

AFIMS currently serves as the investment manager for the Allmerica Investment
Trust. Like the Palladian Trust, the Allmerica Investment Trust consists of a
number of separate portfolios that serve as the underlying investment vehicle
for variable insurance contracts. Each Allmerica Investment Trust portfolio has
a separate subadviser, who serves in a similar capacity to a Portfolio Manager
for a Palladian Trust Portfolio. Fourteen  series of the Allmerica Investment
Trust have commenced operations. Information about each appears in the following
chart.

INFORMATION ABOUT THE NEW MANAGEMENT AGREEMENT

The Management Agreement is set forth in Appendix B. It is substantially
identical to the Management Agreement with PAI, the former manager, except for
substituting the name and address of the new Manager. The agreement provides
that the Manager will recommend Portfolio Managers to the Board of Trustees to
provide day-to-day investment management of each Portfolio; will monitor each
Portfolio Manager and make appropriate recommendations to the Board as to
whether to retain or terminate Portfolio Managers; will coordinate
administrative matters and provide administrative personnel and services; and
will provide reports, consultation, and other reasonable services to the Board.
In the event a Portfolio Manager is terminated or resigns, the agreement
authorizes the Manager to provide day-to-day investment management of that
Portfolio. Pursuant to the agreement, the Manager agrees to act in conformity
with the Trust's registration statement filed with the Securities and Exchange
Commission, with the Board's instructions and directions, and with 
<PAGE>
 
                                       14

all applicable laws and regulations. The agreement requires that the Manager pay
its own expenses, as well as the salaries and other fees and expenses for any
officer or trustee of the Trust who serves as an officer, director, or employee
of the Manager or its affiliates. The agreement requires the Trust to pay for
investment advisory and management fees (which are described below); the Trust's
independent public accountants; the Trust's transfer agent, registrar, and
dividend disbursing agent (if any); the Trust's custodian; costs incurred to
calculate the value of each Portfolio's assets; taxes and costs associated with
maintaining tax records; any salaries of any officers or employees of the Trust
who are not officers, directors, or employees of the Manager or its affiliates;
brokerage fees and commissions in connection with Portfolio transactions; any
costs associated with borrowing by the Trust; costs of communicating with and
providing information to shareholders and regulatory authorities; the Trust's
legal fees; stock certificates; the fees and expenses of Trustees who are
unaffiliated with the Manager; the fidelity bond required under federal
securities laws and any insurance costs; any membership dues for any association
to which the Trust belongs; organizational and offering expenses; and any
extraordinary expenses of the Trust that may arise. The agreement describes the
compensation paid to the Manager. (That compensation is also described below.)
The agreement imposes liability on the Manager for losses caused by the
Manager's breach of fiduciary duty (as limited by certain provisions of the
federal securities laws); willful misfeasance, bad faith, or gross negligence by
the Manager; or reckless disregard by the Manager of its obligations and duties
under the agreement. The Trust may not recover from the Manager for losses
arising from other causes. The agreement specifies that it will terminate if not
approved by persons having voting rights; if so approved, the agreement will
continue for two years, and from year to year afterwards so long as the Board
annually re-approves it. The agreement also provides that it will terminate in
the event of an "assignment" as defined by the 1940 Act (which is essentially a
change of control of the Manager).

INVESTMENT ADVISORY FEES

The fee structure of the new Management Agreement is identical to that of the
old agreement with PAI. That structure is described below. Fees and expenses
under the new Management Agreement will thus be the same as under the old,
except that Allmerica voluntarily has agreed to limit certain expenses as
explained above.

Each Portfolio pays an overall management fee, computed and accrued daily and
paid monthly, based on its average daily net assets. The overall fee varies
based on the performance of that Portfolio (after expenses) compared to that of
an appropriate benchmark. The overall advisory fee is split among the various
advisers in the following manner. The Portfolio Manager receives 80% of the fee,
and AFIMS receives the remaining 20%.

Fixed Advisory Fee For The First Year. For the period beginning on the effective
date of a Portfolio Management Agreement with a new Portfolio Manager (or, in
the case of a new Portfolio, the day on which the Portfolio commenced investment
operations) and ending with the last day of the twelfth full calendar month
thereafter, each Portfolio will pay a monthly advisory fee calculated at an
annual rate of 0.80% of the Portfolio's average daily net assets.

                                       15

Performance-Based Fee. After the first year with a new Portfolio Manager as
described above, each Portfolio pays, at the end of each month, a monthly
advisory fee equal to a Basic Fee plus or minus an Incentive Fee. (As explained
below, the fee might be reduced if absolute performance is negative.)  The
monthly Basic Fee equals one-twelfth of the annual Basic Fee rate of 2.0%
multiplied by average daily net assets over the previous 12 months. The
Incentive Fee rate ranges from -2.0% to +2.0% on an annual basis, depending on a
comparison of the Portfolio's performance (reflecting a deduction of Portfolio
expenses) and the performance of a selected benchmark index over the past 12
months. The monthly Incentive Fee, like the monthly Basic Fee, is calculated by
multiplying one- twelfth of the Incentive Fee rate on an annual basis by the
average daily net assets over the previous 12 months. Accordingly, the Total Fee
could range from 0.0% to an annual rate of 4.0%, depending on performance.

As noted above, performance of both the Portfolio and the selected benchmark
index is calculated on a rolling 12-month period (i.e., the previous 12 months,
including the month for which the fee is being calculated). The performance of a
Portfolio is calculated by first determining the change in the Portfolio's net
asset value per share during the period, assuming the reinvestment of
distributions during that period, and then expressing this amount as a
percentage of the net asset value per share at the beginning of the period. Net
asset value per share is calculated by dividing the value of the securities held
by the Portfolio plus any cash or other assets minus all liabilities including
accrued advisory fees and the other expenses, by the total number of shares
outstanding at the time. The performance of the selected benchmark index is
calculated as the sum of the change in the level of the index during the period,
plus the value of any dividends or distributions made by the companies whose
securities comprise the index accumulated to the end of the period, and then
expressing that amount as a percentage of the index at the beginning of the
period.

No Incentive Fee will be paid if the Portfolio's performance equals the targeted
performance --selected benchmark index plus 2.25 percentage points. The maximum
fee will be paid if performance is 5.25 percentage points higher than the target
(i.e., 7.5 percentage points higher than the selected benchmark index). No fee
will be paid if performance is 5.25 percentage points lower than the target
(i.e., more than 3 percentage points below the selected benchmark index). The
chart below further explains the Incentive Fee at various performance levels.

Maximum Fee If Performance Is Negative. Notwithstanding the above schedule, if
the absolute performance of a Portfolio (after payment of all expenses,
including the Basic Fee and any Incentive Fee) after the first year is negative,
the monthly advisory fee will be the lesser of the fee calculated pursuant to
the above schedule or the alternative monthly advisory fee described below,
which under certain circumstances results in the Portfolios paying either no
advisory fee or a lower monthly advisory fee than under the performance fee
schedule above. If a Portfolio's performance (after payment of all expenses
including advisory fees) is negative and does not exceed the selected benchmark
by six percentage points (on an annual basis), no monthly advisory fee will be
paid. If the Portfolio's performance (after payment of all expenses including
advisory fees) is negative and does not exceed the selected benchmark by twelve
percentage points but does exceed the selected benchmark by six percentage
points (on an annual basis), the alternate monthly advisory fee will be based on
an annual rate of 1.0% of average daily net assets over the previous 12 months.
If, on the other hand, the performance of a Portfolio (after payment of all
expenses including advisory fees) is negative but exceeds the selected benchmark
by twelve percentage points or more (on an annual basis), the alternative
monthly advisory fee will be based on an annual rate of 2.0% of average daily
net assets over the previous 12 months.

Size of Fee. The Basic Fee payable by the Portfolios after the first year is at
a rate higher than the investment advisory fees paid by most other investment
companies. If a Portfolio outperforms the selected benchmark by 3.0 percentage
points or more, the advisory fee payable by a Portfolio may further exceed those
paid by other investment companies. On the other hand, if a Portfolio
underperforms the selected benchmark, the advisory fee paid by the Portfolio may
be less than those paid by other investment companies. If, during the applicable
performance period, a Portfolio underperforms the selected  benchmark  by three
or more percentage points, the Portfolio will not pay any advisory fee, although
the Manager, Portfolio Advisor and Portfolio Managers will remain obligated to
provide the Portfolio with the services contemplated herein as long as they are
in effect.

Performance Benchmarks. As described above, total advisory fees paid to each
Portfolio Manager for advising the Portfolios are based on the performance of
the Portfolio they manage relative to a market benchmark selected in light of
the investment objective and policies of the Portfolio. The performance
benchmarks selected for the Portfolios are listed below and described in more
detail in the prospectus.

RELATIONSHIP WITH PROPOSAL NO. 3.

Each Portfolio will vote separately on this Proposal. AFIMS will continue to
serve as overall Manager for each Portfolio for which persons having voting
rights approve both this Proposal AND, if applicable, Proposal No. 3, which
would substitute AFIMS for the previous Manager in each Portfolio's separate
Portfolio Management Agreement. This means that for the Value, Growth,
International Growth, and Global Interactive/Telecomm Portfolios, persons having
voting rights with respect to the Portfolio must approve both Proposals for
AFIMS to continue to serve as overall Manager of that Portfolio. Persons having
voting rights with respect to the Global Strategic Income Portfolio do not vote
on Proposal 3, and AFIMS will continue as overall Manager for that Portfolio if
persons having voting rights approve this Proposal only.

In the event that persons having voting rights with respect to a particular
Portfolio do not approve this Proposal or, if applicable, both this Proposal and
Proposal 3, then AFIMS will cease serving as overall Manager to that Portfolio
as of June 11, 1998, and the Board will meet to consider appropriate action with
regard to that Portfolio.


REQUIRED VOTE

Each Portfolio will vote separately on this Proposal No. 2. The Proposal will be
adopted by a Portfolio if a majority of outstanding shares of the Portfolio vote
FOR approval of the Proposal. The 1940 Act defines a majority of outstanding
shares of a Portfolio as the lesser of (a) a vote of 67% or more of the
Portfolio's shares whose holders are present or represented by proxy at the
meeting if the holders of more than 50% of all outstanding Portfolio's shares
are present in person or represented by proxy at the meeting, or (b) a vote of
more than 50% of all outstanding Portfolio shares.

THE BOARD RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL NO. 2.

                                 PROPOSAL NO. 3

                       APPROVAL OF AGREEMENTS UNDER WHICH
            ALLMERICA FINANCIAL INVESTMENT MANAGEMENT SERVICES, INC.
                 IS SUBSTITUTED FOR THE PREVIOUS MANAGER UNDER
                      THE PORTFOLIO MANAGEMENT AGREEMENTS


Persons having voting rights with respect to the following Portfolios (the
"Affected Portfolios") will vote on this proposal:

    .     Value Portfolio
    .     Growth  Portfolio
    .     International Growth Portfolio
    .     Global Interactive/Telecomm Portfolio

Persons having voting rights only with respect to the Global Strategic Income
Portfolio will not vote on this proposal.

The Portfolio Manager for each Portfolio provides the day-to-day investment
management of the Portfolio pursuant to a Portfolio Management Agreement. The
parties to that agreement include the Portfolio Manager, the Trust, and the
overall Manager.  As explained above in connection with Proposal 2, the Trust
has a new Manager.  Initially the new Manager was Allmerica Investment
Management Company, Inc. ("AIMCO").  The parties executed "substitution
agreements" substituting AIMCO as the new Manager under the Portfolio Management
Agreement.  As part of a corporate reorganization on April 16, 1998, AIMCO
transferred to AFIMS that portion of its business relating to registered
investment companies such as the Trust.  The same personnel and procedures
previously employed by AIMCO to service the Trust are used by AFIMS.   Thus,
while AIMCO is the signatory to the substitution agreement, AFIMS has assumed
AIMCO's role under those agreements.

Although no Portfolio Management Agreement for the Affected Portfolios will
change in any material respect other than substituting AIMCO (and now its
successor AFIMS) for PAI, that substitution technically results in a new or
amended agreement. Accordingly, this Proposal submits the substitution
agreements for the approval of persons having voting rights.

As explained above in connection with Proposal 2, the Board of Trustees
concluded at its February 11, 1998 meeting that the best interests of the Trust
would be served if AIMCO (the predecessor to AFIMS) replaced PAI as Manager. The
Board accordingly approved the substitution agreements.

The form of substitution agreement appears in Appendix C. It provides that AIMCO
will replace PAI as a party to the respective Portfolio Management Agreement.
AFIMS (as successor to AIMCO) now has responsibility for any duty formerly
assigned to PAI and arising after the date of the agreement.
<PAGE>
 
                                       19

The Portfolio Management Agreements for each Portfolio will not change, other
than the substitution of the new Manager of the Trust. Each Portfolio will
continue to have the same Portfolio Manager responsible for day-to-day
management of the Portfolio's investments. Each Portfolio Management Agreement
provides generally that the Portfolio Manager will provide research services and
make decisions about what securities and other instruments the Portfolio will
invest in. The Portfolio Manager must make investment decisions for the
Portfolio in conformity with the Portfolio's investment objective and policies.
The Portfolio Manager must, under the applicable Portfolio Management Agreement,
comply with applicable laws and regulations. The Portfolio Manager must also
provide information about Portfolio transactions to the Trust's custodian.
Pursuant to each Portfolio Management Agreement, the Portfolio Manager must
provide information and reports to the Board of Trustees.  Each Portfolio
Management Agreement specifies that the Portfolio Manager must pay its own
expenses and salaries and fees of any officer or trustee of the Trust who is an
officer, director, or employee of the Portfolio Manager. The Portfolio Manager
is not otherwise responsible for the Trust's or a Portfolio's expenses. Each
Portfolio Management Agreement imposes liability on a Portfolio Manager for
losses caused by the Portfolio Manager's breach of fiduciary duty (as limited by
certain provisions of the federal securities laws); willful misfeasance, bad
faith, or gross negligence by the Portfolio Manager; or reckless disregard by
the Portfolio Manager of its obligations and duties under the agreement. The
Trust may not recover from the Portfolio Manager for losses arising from other
causes. The Portfolio Management Agreement provides that it will terminate in
the event of an "assignment" (which is essentially a change of control of the
Portfolio Manager), but will otherwise continue so long as on the Board of
Trustees re-approves it annually.

Each Portfolio Management Agreement also describes the fee structure for the
particular Portfolio. The substitution agreements will not have any effect on
                                                       ---
that fee structure. A description of the fee structure for each Portfolio
appears above in connection with Proposal 2. Additional information about AFIMS
also appears above in connection with Proposal 2. Information about the
Portfolio Managers appears in Appendix A.

With respect to each Affected Portfolio, the Proposal will go into effect only
if persons having voting rights with respect to the Portfolio approve both this
Proposal and Proposal No. 2. For more information, see Proposal No. 2.

REQUIRED VOTE

The Affected Portfolios will each vote on this Proposal separately. The Proposal
will be adopted by a Portfolio if a majority of outstanding shares of the
Portfolio vote FOR approval of the Proposal. The 1940 Act defines a majority of
outstanding shares of a Portfolio as the lesser of (a) a vote of 67% or more of
the Portfolio's shares whose holders are present or represented by proxy at the
meeting if the holders of more than 50% of all outstanding Portfolio's shares
are present in person or represented by proxy at the meeting, or (b) a vote of
more than 50% of all outstanding Portfolio shares.

                                 PROPOSAL NO. 4

               APPROVAL OF A NEW PORTFOLIO MANAGEMENT AGREEMENT,
              PURSUANT TO WHICH ALLMERICA ASSET MANAGEMENT, INC.
                       WOULD SERVE AS PORTFOLIO MANAGER
                   TO THE GLOBAL STRATEGIC INCOME PORTFOLIO


Only persons having voting rights with respect to the Global Strategic Income
Portfolio will vote on this proposal.

Since the Trust commenced operations in 1996, Fischer Francis Trees & Watts
("Fischer Francis") has served as Portfolio Manager to the Global Strategic
Income Portfolio (the "Portfolio"). In response to a request from Fischer
Francis that it be replaced as Portfolio Manager, at an April 9, 1998 meeting,
the Board approved an agreement terminating the Portfolio Management Agreement
with Fischer Francis as of the close of business on April 10, 1998.  At that
meeting, the Board also approved a new Portfolio Management Agreement with
Allmerica Asset Management Company, Inc. ("AAM") to serve as Portfolio Manager
to the Global Strategic Income Portfolio. AAM is an affiliate of AFIMS, the
current overall Trust Manager, and has expertise in investing in fixed-income
securities.

This Proposal submits the Portfolio Management Agreement with AAM for the
approval of persons having voting rights with respect to the Portfolio.  If
approved, the Portfolio Management Agreement will continue indefinitely so long
as the Board approves the agreement annually.

INFORMATION ABOUT THE NEW PORTFOLIO MANAGEMENT AGREEMENT

The new Portfolio Management Agreement with AAM is substantially identical to
the previous agreement with Fischer Francis.  This paragraph summarizes
provisions common to both agreements.  The agreement provides generally that the
Portfolio Manager will provide research services and make decisions about what
securities and other instruments the Portfolio will invest in. The Portfolio
Manager must make investment decisions for the Portfolio in conformity with the
Portfolio's investment objective and policies. The Portfolio Manager must, under
the Portfolio Management Agreement, comply with applicable laws and regulations.
The Portfolio Manager must also provide information about Portfolio transactions
to the Trust's custodian. Pursuant to the 
<PAGE>
 
                                       23

Portfolio Management Agreement, the Portfolio Manager must provide information
and reports to the Board of Trustees. The Portfolio Management Agreement
specifies that the Portfolio Manager must pay its own expenses and salaries and
fees of any officer or trustee of the Trust who is an officer, director, or
employee of the Portfolio Manager. The Portfolio Manager is not otherwise
responsible for the Trust's or the Portfolio's expenses. The Portfolio
Management Agreement imposes liability on a Portfolio Manager for losses caused
by the Portfolio Manager's breach of fiduciary duty (as limited by certain
provisions of the federal securities laws); willful misfeasance, bad faith, or
gross negligence by the Portfolio Manager; or reckless disregard by the
Portfolio Manager of its obligations and duties under the agreement. The Trust
may not recover from the Portfolio Manager for losses arising from other causes.
The Portfolio Management Agreement provides that it will terminate in the event
of an "assignment" (which is essentially a change of control of the Portfolio
Manager), but will otherwise continue so long as on the Board of Trustees re-
approves it annually.

The new Portfolio Management Agreement differs from the previous agreement with
Fischer Francis in one material respect. Under the previous agreement with
Fischer Francis, the relevant benchmark for comparing performance and computing
the Portfolio Manager's compensation was the JP Morgan Global Governmental Bond
Index, Unhedged, an index intended to measure the global government bond market
of 13 countries weighted by market capitalization. This benchmark reflected the
Portfolio's global focus. As explained below in connection with Proposal 5,
however, the Board has approved a change in the Portfolio's objective to remove
the global emphasis, and has submitted that proposed change for the approval of
persons having voting rights. Because AAM and the Board anticipate that the
Portfolio will focus more on domestic fixed-income securities, the agreement was
changed to make the relevant benchmark the Lehman Brothers Aggregate Bond Index.
This index measures the overall domestic bond market and combines four other
indices: the Lehman Brothers Government Bond Index, which tracks the returns of
U.S. Treasuries, agency bonds, and one- to three- year U.S. government
obligations; the Lehman Brothers Corporate Bond Index, which tracks the returns
of all publicly issued, fixed-rate, nonconvertible, dollar-denominated,
investment-grade corporate debt registered with the Securities and Exchange
Commission; the Lehman Brothers Mortgage-Backed Securities Index, which includes
15- and 30-year fixed-rate securities backed by mortgage pools issued by GNMA,
FNMA, and FHLMC; and the Lehman Brothers Asset-Backed Securities Index, which
tracks fixed-income securities that represent a participation in, or are secured
by and payable from, a stream of payments generated by particular assets (for
example, trade receivables).

The fee structure of the new Portfolio Management Agreement is the same as under
the old Portfolio Management Agreement with Fischer Francis (except for the
change in performance benchmark) and is described above in connection with
Proposal 2. The new Portfolio Management Agreement will result in one change
relating to fees, however. Under the new agreement (as under the former
agreement), during a Portfolio Manager's first year serving in that capacity,
rather than paying a performance-based fee, the Portfolio will pay a fixed fee
of 0.80% of average daily net assets. After the twelfth full calendar month has
elapsed under the agreement, the performance-based fee will be in effect.
Fischer Francis had already served as Portfolio Manager for a full year, so the
performance-
<PAGE>
 
                                       24

based fee structure was in effect. AAM has not served as Portfolio Manager for a
year, so the Portfolio will pay a fixed fee of 0.80% of average daily net assets
until that year has elapsed.

AAM's fee is subject to an additional limitation.  From the time that AAM
assumed the role of Portfolio Manager until shareholders approve the new
agreement, the Trust will pay AAM the lesser of the following two fees:  (1) the
                                      ------
0.80% fee set by the new agreement; and (2) the fee that Fischer Francis would
have been paid.

ADDITIONAL FEE INFORMATION

1997 Fee Information. The following table summarizes the expenses of the

Pro Forma Fee Information. The following table shows an estimate of what 1997
expenses would have been had AAM served as subadviser for the Portfolio under
the new Portfolio Manager Agreement.  The table assumes that AAM became
Portfolio Manager on January 1, 1997 and thus the one-year start-up fee of 0.80%
was in effect for all of 1997.  As in the first table, expenses are expressed as
a percentage of average net assets during the year. Expenses reflect applicable
expense limitations currently in effect. This table and example do not include
any expenses charged under any variable contract, such as sales charges or

BOARD CONSIDERATION

On April 9, 1998, the Board of Trustees met in person to consider the proposed
Portfolio Management Agreement with AAM. Representatives from AAM made a
presentation to the Board, and the Board was provided with materials about AAM,
its investment philosophies and strategies, its key personnel, its other
clients, and examples of performance.  The Board considered the terms of the
Portfolio Management Agreement and the fact that it was substantially identical
to the prior agreement. The Board also considered the proposed change in
performance benchmark, which it 
<PAGE>
 
                                       26


concluded adequately reflected the Portfolio's proposed new investment
objective. Finally, the Board considered the fairness of the proposed fee, the
fact that it had the same rate structure as under the previous agreement, and
that the performance-based fee structure would not begin until AAM had served as
Portfolio Manager for a year. The Board concluded that entering into the new
Portfolio Management Agreement with AAM was in the best interests of the
Portfolio and its investors. Accordingly, the Board voted unanimously to approve
the proposed agreement.

REQUIRED VOTE

The proposal will be adopted if it is approved by the vote of a majority of
outstanding shares of the Global Strategic Income Portfolio. The 1940 Act
defines a majority of outstanding shares of a Portfolio as the lesser of (a) a
vote of 67% or more of the Portfolio's shares whose holders are present or
represented by proxy at the meeting if the holders of more than 50% of all
outstanding Portfolio's shares are present in person or represented by proxy at
the meeting, or (b) a vote of more than 50% of all outstanding Portfolio shares.

THE BOARD RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL NO. 4.

                                       27

                                PROPOSAL NO. 5

                    APPROVAL OF A NEW INVESTMENT OBJECTIVE
                   FOR THE GLOBAL STRATEGIC INCOME PORTFOLIO

Only persons having voting rights with respect to the Global Strategic Income
Portfolio (the "Portfolio") will vote on this Proposal.

Each Portfolio has certain investment policies that are fundamental, which means
they cannot be changed without shareholder approval and other investment
policies that are non-fundamental, which the Board of Trustees may change
without shareholder approval.

The Portfolio's current investment objective, which is a fundamental investment
policy, specifies that the Portfolio invest in both domestic and foreign-fixed
income securities. This proposal would change the Portfolio's investment
objective to remove the global emphasis. The revised investment objective would
thus de-emphasize investment in foreign fixed-income securities, although the
Portfolio would continue to have the ability to invest in some foreign fixed-
income securities.

If persons having voting rights approve this Proposal, the name of the Portfolio
will be changed to the "Strategic Income Portfolio" to reflect the new
investment objective. In addition, the Board has adopted new non-fundamental
investment policies consistent with the new investment objective. These new
policies will become effective if and when this Proposal is approved.  As
explained above in connection with Proposal 4, the Board has proposed that
Allmerica Asset Management, Inc. ("AAM") continue serving as Portfolio Manager
of the Portfolio. The proposed changes will make the Portfolio's investment
policies similar to those of other portfolios currently managed by AAM.

INVESTMENT OBJECTIVE

The Global Strategic Income Portfolio (the "Portfolio") currently has the
following investment objective, which is fundamental:

     THE GLOBAL STRATEGIC INCOME PORTFOLIO seeks to make money for investors by
     investing for high current income and capital appreciation in a variety of
     domestic and foreign fixed-income securities.

If this Proposal is adopted, the Portfolio's investment objective will change to
the following:

     THE STRATEGIC INCOME PORTFOLIO seeks to make money for investors by
     investing for high current income and capital appreciation in a variety of
     fixed-income securities.

The new investment objective would focus thus eliminate the reference to foreign
fixed-income securities.
<PAGE>
 
                                       28

NON-FUNDAMENTAL INVESTMENT POLICIES

If persons having voting rights approve this Proposal, the Board will also adopt
the following non-fundamental investment policies:

     The Portfolio allocates its assets among debt securities in three separate
     areas: 1) investment grade corporate debt securities and securities issued
     or guaranteed as to principal or interest by the U.S. Government or its
     agencies or instrumentalities; 2) below investment-grade corporate debt
     securities; and 3) foreign securities which include government debt of
     developed and emerging markets, corporate obligations of foreign companies,
     and debt obligations of supranational entities. The Portfolio will select
     particular debt securities based on their relative value merits.

     Debt securities in which the Strategic Income Portfolio may invest include
     bonds, notes, debentures, mortgage-backed and asset-backed securities, and
     other similar instruments. The Portfolio normally invests at least 50% of
     its total assets in U.S. and foreign debt and other fixed-income securities
     that, at the time of purchase, are investment grade. The Strategic Income
     Portfolio may consider making carefully selected investments in below
     investment-grade quality (also called high yield or junk bonds), which
     involve a high degree of risk and are predominantly speculative. Consistent
     with the foregoing percentage limitations, the Portfolio may invest in
     securities that are in default in payment of principal and/or interest.

     Investments in foreign markets involve substantial risks typically not
     associated with investing in the United States. Emerging market securities
     generally are subject to greater risk than securities from developed
     nations. For purposes of the Portfolio's operations, "emerging markets"
     consist of all countries determined by the Portfolio Manager to have
     developing or emerging economies and markets.

     The Strategic Income Portfolio also may invest up to 5% of its assets in
     loan participations and assignments.

These new investment policies differ from the current ones by eliminating
certain policies specific to foreign securities. This change is consistent with
the new investment objective's decreased focus of foreign fixed-income
securities.

Although foreign securities may involve different risks than domestic
securities, under both the old and new policies, the Portfolio must invest at
least 50% of total assets in investment-grade fixed-income securities, and may
invest up to 50% of total assets in fixed-income securities rated below
investment grade. Accordingly, AAM does not anticipate that investment risk will
necessarily decrease as a result of the new policies.

REQUIRED VOTE

The proposal will be adopted if it is approved by the vote of a majority of
outstanding shares of the Global Strategic Income Portfolio. The 1940 Act
defines a majority of outstanding shares of a Portfolio as the lesser of (a) a
vote of 67% or more of the Portfolio's shares whose holders are present or
represented by proxy at the meeting if the holders of more than 50% of all
outstanding Portfolio's shares are present in person or represented by proxy at
the meeting, or (b) a vote of more than 50% of all outstanding Portfolio shares.

Neither the Board nor Allmerica is currently aware of any other matters that
will be considered at the meeting. In the event any additional business or
matter is properly presented to the meeting, Allmerica will vote your properly
executed voting instruction form in accordance with its best judgment.

                        INVESTMENT MANAGEMENT AGREEMENT
                        -------------------------------

          Agreement, made the 12th day of February, 1998, and amended the ___
day of April, 1998, between The Palladian Trust (the "Trust"), a Massachusetts

company registered under the Investment Company Act of 1940, as amended (the
"1940 Act"); and

          WHEREAS, the Manager is registered as an investment adviser under the
Investment Advisers Act of 1940; and

          WHEREAS, the Trust is authorized to issue shares of beneficial
interest in separate portfolios with each such portfolio representing interests
in a separate portfolio of securities and other assets; and

          WHEREAS, the Trust currently offers shares of five portfolios
designated as The Value Portfolio, The Growth Portfolio, The International
Growth Portfolio, The Global Strategic Income Portfolio, and The Global
Interactive/Telecomm Portfolio (collectively, the "Current Portfolios"); and

          WHEREAS, the Trust may establish additional portfolios with respect to

hereunder and with respect to which the Manager is willing to do so (those
portfolios plus the Current Portfolios are collectively referred to as the

management services with respect to the Current Portfolios for the period and on
the terms set forth in this Agreement, subject to the direction of the Board of
Trustees of the Trust (the "Board of Trustees"). The Manager accepts such
appointment and agrees to render the services described herein for the
compensation provided in paragraph 9.  In the event the Trust establishes one or
more portfolios other than the Current Portfolios with respect to which it
desires to retain the Manager to render management services pursuant to this
Agreement, it shall so notify the Manager in writing.  If the Manager is willing

     2.   Services of the Manager.  Subject to the supervision of the Board of
          -----------------------                                             
Trustees, the Manager shall provide the following management services with
respect to the Portfolios:
 
          (a) The Manager shall analyze and recommend for consideration by the
Board of Trustees investment advisory firms to be retained by the Trust to
provide day-to-day investment management of the Portfolios (the "Portfolio
Managers").

          (b) The Manager shall monitor and evaluate the performance of the
Portfolio Managers and make recommendations to the Board of Trustees concerning
the renewal or termination of agreements with Portfolio Managers (the "Portfolio
Management Agreements"), although the Manager is not authorized, except as
provided in paragraph 3 of the Agreement, to make determinations with respect to
the investment of a Portfolio's assets or the purchase or sale of securities or
other investments for a Portfolio.

          (c) The Manager shall monitor the Portfolio Managers for compliance
with the investment policies and restrictions of each Portfolio, the 1940 Act,
the Internal Revenue Code, and all other applicable federal and state laws and
regulations.

          (d) The Manager shall coordinate all matters relating to the functions
of the Trust's Manager, Portfolio Managers, custodian, transfer agent,
accountants, attorneys, and other parties performing services or operational
functions for the Trust.

          (e) The Manager shall provide the Trust and the Portfolios with the
services of a sufficient number of persons competent to perform such
administrative and clerical functions as are necessary to provide effective
supervision and administration of the Trust.

          (f) The Manager shall provide the Trust with adequate office space,
communications facilities, and other facilities necessary for its operations as
contemplated in this Agreement.

          (g) The Manager shall provide the Board of Trustees such periodic and
special reports as the Board may reasonably request.
<PAGE>
 
                                       36

          (h) The Manager shall make its officers and employees available to the
Board of Trustees and officers of the Trust for consultation and discussions
regarding the administration and management of the Trust.

          (i) The Manager shall provide such assistance as the Board of Trustees
shall reasonably request in connection with the conduct of meetings of the Board
or otherwise.

     3.   Investment Management Authority.  In the event that a Portfolio
          -------------------------------                                
Management Agreement pertaining to a Portfolio is terminated or if, at any time,
no Portfolio Manager is engaged to manage the assets of a Portfolio, then the
Manager, subject to the supervision of the Board of Trustees, will provide day-
to-day investment management of any such Portfolio.  The Manager will provide
investment research and conduct a continuous program of evaluation, investment,
sales, and reinvestment of the Portfolio's assets by determining the securities
and other investments that shall be purchased, entered into, sold, closed, or
exchanged for the Portfolio, when these transactions should be executed, and
what portion of the assets of the Portfolio should be held in the various
securities and other investments in which it may invest.  The Manager is hereby
authorized to execute and perform such services on behalf of the Portfolio.  To
the extent permitted by the investment policies of the Portfolio, the Manager
shall make decisions for the Portfolio as to foreign currency matters and make
determinations as to, and execute and perform, foreign currency exchange
contracts on behalf of the Portfolio.  The Manager will provide the services
under this Agreement in accordance with the Portfolio's investment objective or
objectives, policies, and restrictions as stated in the Trust's registration
statement under the Securities Act of 1933 and the 1940 Act as filed with the
Securities and Exchange Commission ("SEC") and amended from time to time (the
"Registration Statement").  Furthermore, under these circumstances:

          (a) The Manager will use reasonable efforts to manage the Portfolio so
that it will (1) qualify as a regulated investment company under Subchapter M of
the Internal Revenue Code, (2) comply with the diversification requirements of
Section 817(h) of the Internal Revenue Code and regulations issued thereunder,
and (3) comply with any other rules and regulations pertaining to investment
vehicles underlying variable annuity or variable life insurance policies.  In
managing the Portfolio in accordance with these requirements, the Manager shall
be entitled to receive and act upon advice of counsel to the Trust or counsel to
the Manager.

          (b) On occasions when the Manager deems the purchase or sale of a
security to be in the best interest of the Portfolio as well as any other
investment advisory clients, the Manager may, to the extent permitted by
applicable laws and regulations, including, but not limited to Section 17(d) of
the 1940 Act, but shall not be obligated to, aggregate the securities to be so
sold or purchased with those of its other clients where such aggregation is not
inconsistent with the policies set forth in the Registration Statement.  In such
event, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by the Manager in a manner
that is fair and equitable in the judgment of the Manager in the exercise of its
fiduciary obligations to the Trust and to such other clients.
<PAGE>
 
                                       37

          (c) In connection with the purchase and sale of securities for the
Portfolio, the Manager will arrange for the transmission to the custodian for
the Trust on a daily basis, such confirmation, trade tickets, and other
documents and information as may be reasonably necessary to enable the custodian
to perform its administrative and recordkeeping responsibilities with respect to
the Portfolio.  With respect to portfolio securities to be purchased or sold
through the Depository Trust Company, the Manager will arrange for the automatic
transmission of the confirmation of such trades to the Trust's custodian.
 
          (d) The Manager will assist the custodian or recordkeeping agent for
the Trust in determining, consistent with the procedures and policies stated in
the Registration Statement, the value of any portfolio securities or other
assets of the Portfolio for which the custodian or recordkeeping agent seeks
assistance or review from the Manager.  The Manager will monitor on a daily
basis the determination by the custodian or recordkeeping agent for the Trust
the value of portfolio securities and other assets of the Portfolio and the
determination of net asset value of the Portfolio.

          (e) The Manager will regularly report to the Board of Trustees on the
investment program for the Portfolio, and will furnish the Board of Trustees
such periodic and special reports as the Board may reasonably request.

          (f) In rendering the services required under this paragraph, the
Manager may, from time to time, employ or associate with itself such person or
persons as it believes necessary to assist it in carrying out its obligations
under this Agreement.  The Manager shall be responsible for making reasonable
inquiries and for reasonably ensuring that any employee of the Manager, any
person or firm that the Manager has employed or with which it has associated, or
any employee thereof involved in any material connection with the handling of
Trust assets, has not, to the best of the Manager's knowledge:

               (i)   been convicted, in the last ten (10) years, of any felony
     or misdemeanor arising out of conduct involving embezzlement, fraudulent
     conversion, or misappropriation of funds or securities, or involving
     violations of Sections 1341, 1342, or 1343 of Title 18, United States Code;
     or

               (ii)  been found by any state regulatory authority, within the
     last ten (10) years, to have violated or to have acknowledged violation of
     any provision of any state insurance law involving fraud, deceit, or
     knowing misrepresentation; or

               (iii) been found by any federal or state regulatory authorities,
     within the last ten (10) years, to have violated or to have acknowledged
     violation of any provisions of federal or state securities laws involving
     fraud, deceit, or knowing misrepresentation.

          (g)  In connection with its responsibilities under this paragraph 3,
the Manager is responsible for decisions to buy and sell securities and other
investments for the Portfolio, broker-
<PAGE>
 
                                       38

dealer selection, and negotiation of brokerage commission rates. The Manager's
primary consideration in effecting a security transaction will be to obtain the
best execution for the Portfolio, taking into account the factors specified in
the Registration Statement. Subject to the Registration Statement and such
policies as the Board of Trustees may determine and consistent with Section
28(e) of the Securities Exchange Act of 1934, the Manager shall not be deemed to
have acted unlawfully or to have breached any duty created by this Agreement or
otherwise solely by reason of its having caused the Portfolio to pay a broker-
dealer for effecting a portfolio investment transaction in excess of the amount
of commission another broker-dealer would have charged for effecting that
transaction, if the Manager or its affiliate 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-dealer, viewed in terms of either
that particular transaction or the Manager's overall responsibilities with
respect to the Portfolio and to its other clients as to which it exercises
investment discretion.

     4.   Conformity with Applicable Law.  The Manager, in the performance of
          ------------------------------                                     
its duties and obligations under this Agreement, shall act in conformity with

of Trustees and will conform to, and comply with, the requirements of the 1940
Act and all other applicable federal and state laws and regulations.

     5.   Exclusivity.  The services of the Manager under this Agreement are not
          -----------

and it will promptly surrender any of such records upon request.

     9.   Compensation.
          ------------ 

          (a) For the services provided and the expenses borne by the Manager
pursuant to this Agreement, each Portfolio will pay the Manager a fee calculated
in accordance with this paragraph 9.

          (b) A Portfolio will pay the Manager 20% of the Initial Monthly
Advisory Fee or the Monthly Advisory Fee, as those terms are defined in this
paragraph, whichever is applicable; provided, however, that for any period
during which the Manager is providing the services described in paragraph 3,  a
Portfolio will pay the Manager 100% of the Initial Monthly Advisory Fee or the
Monthly Advisory Fee, as those terms are defined in this paragraph, whichever is
applicable.

          (c) For the period beginning with the effective date of a Portfolio
Management Agreement with a new Portfolio Manager (or, for those Portfolios that
have had only one Portfolio Manager, the day on which the Portfolio commenced
operations) and ending with the last day of the twelfth full calendar month
thereafter, the Portfolio will pay at the end of each month, an advisory fee
calculated at an annual rate of 0.80% of the Portfolio's average daily net
assets (the "Initial Monthly Advisory Fee").

          (d) For the period beginning with the first day of the thirteenth full
calendar month after the effective date of a Portfolio Management Agreement with
a new Portfolio Manager (or, for those Portfolios that have had only one
Portfolio Manager, the first day of the thirteenth full calendar month after the

of this Agreement, the Portfolio will pay at the end of each month, an advisory
fee (the "Monthly Advisory Fee").  The Monthly Advisory Fee equals the Basic Fee

<PAGE>
 
                                       41


9(e) below) plus the Incentive Fee (as defined in paragraph 9(f) below) and
adjusted, if so required, by paragraph 9(i) below.

          (e) The Basic Fee equals one-twelfth of 2% multiplied by the
Portfolio's average daily net assets for the previous 12 months (including the
month for which the fee is being calculated).

          (f) The Incentive Fee equals:  (i) one-twelfth of the Annual Incentive
Fee set forth in the chart below based on the difference between the Performance
of the Portfolio and the Performance of the Benchmark, as those terms are
defined in paragraphs 9(g) and 9(h) below; (ii) multiplied by the Portfolio's

          (g) The Performance of the Portfolio will be calculated by first
determining the change in the Portfolio's net asset value per share during the
previous twelve months (including the month for which the fee is being computed)
assuming the reinvestment of distributions during that period, and then
expressing this amount as a percentage of the net asset value per share at the
beginning of the period.  Net asset value per share is calculated by dividing
the value of the securities held by the Portfolio plus any cash or other assets
minus all liabilities including accrued advisory fees and the other expenses, by
the total number of shares outstanding at the time.  The Performance of the
Portfolios shall be calculated in accordance with SEC rules.

          (h) The Performance of the Benchmark will be calculated by first
determining the change in the level of the Benchmark during the previous twelve
months (including the month for which the fee is being computed) plus the value
of any cash dividends or distributions made by the companies whose securities
comprise the Benchmark accumulated to the end of the period, and then 
<PAGE>
 
                                       42

expressing this amount as a percentage of the Benchmark at the beginning of the
period. The Performance of the Benchmark shall be calculated in accordance with
SEC rules. The Benchmark for each Portfolio is the Benchmark established by the
agreement between the Trust and the Portfolio Manager for that Portfolio. If any
Benchmark ceases to be published, changes in any material respect or otherwise
becomes impracticable to use for purposes of the Incentive Fee, the Monthly
Advisory Fee for that Portfolio will equal the Basic Fee (with no incentive
adjustment) until such time as the Board of Trustees approves a substitute
Benchmark.

          (i) Notwithstanding paragraphs 9(a)-9(h) above, if the Performance of
a Portfolio (minus payment of all expenses, including the Basic Fee and any
Incentive Fee) is negative and does not exceed the Performance of the Benchmark
by six percentage points, then the Monthly Advisory Fee will equal zero.
Notwithstanding paragraphs 9(a)-9(h) above, if the Performance of a Portfolio
(minus payment of all expenses, including the Basic Fee and any Incentive Fee)
is negative, exceeds the Performance of the Benchmark by six percentage points,
but does not exceed the Performance of the Benchmark by twelve percentage
points, then the Monthly Advisory Fee will not be greater than one-twelfth of 1%
of the Portfolio's average daily net assets for the previous 12 months
(including the month for which the fee is being calculated).  Notwithstanding
paragraphs 9(a)-9(h) above, if the Performance of a Portfolio (minus payment of
all expenses, including the Basic Fee and any Incentive Fee) is negative and
exceeds the Performance of the Benchmark by twelve percentage points, then the
Monthly Advisory Fee will not be greater than one-twelfth of 2% of the
Portfolio's average daily net assets for the previous 12 months (including the
month for which the fee is being calculated).

     10.  Liability and Indemnification.  The Manager and the Trust each may
          -----------------------------                                     
rely on information reasonably believed by it to be accurate and reliable.  The
Manager shall not be liable for any loss suffered by the Trust as the result of
actions by persons other than the Manager or for any loss suffered by the Trust
as the result of any negligent act or error of judgment of the Manager in
connection with the matters to which this Agreement relates, except a loss
resulting from a breach by the Manager of its fiduciary duty with respect to the
receipt of compensation for services (in which case any award of damages shall
be limited to the period and the amount set forth in Section 36(b)(3) of the
1940 Act) or loss resulting from willful misfeasance, bad faith or gross
negligence on its part in the performance of its duties under this Agreement or
from reckless disregard by it of its obligations and duties under this
Agreement.  The Trust shall indemnify the Manager and hold it harmless from all
cost, damage and expense, including reasonable expenses for legal counsel,
incurred by the Manager resulting from actions for which it is relieved of
responsibility by this paragraph.  The Manager shall indemnify the Trust and
hold it harmless from all cost, damage and expense, including reasonable
expenses for legal counsel, incurred by the Trust resulting from (i) a breach by
the Manager of its fiduciary duty with respect to compensation for services paid
by the Trust (in which case any award of damages shall be limited to the period
and the amount set forth in Section 36(b)(3) of the 1940 Act); (ii) willful
misfeasance, bad faith or gross negligence by the Manager in the performance of
its duties under this Agreement; or (iii) reckless disregard by the Manager of
its obligations and duties under this Agreement.

event that continuance is also approved by the vote of a majority of the Board
of Trustees who are not parties to this Agreement or "interested persons" (as
defined in the 1940 Act) of the Trust or the Manager, cast in person at a
meeting called for the purpose of voting on such approval.  Any approval of this
Agreement by the holders of a majority of the outstanding shares (as defined in
the 1940 Act) of a Portfolio shall be effective to continue this Agreement with
respect to such Portfolio notwithstanding (i) that this Agreement has not been
approved by the holders of a majority of the outstanding shares of any other
Portfolio or (ii) that this Agreement has not been approved by the vote of a
majority of the outstanding shares of the Trust, unless such approval shall be
required by any other applicable law or otherwise.  This Agreement may be
terminated by the Trust at any time, without the payment of any penalty, by vote
of a majority of the entire Board of Trustees or by a vote of a majority of the
outstanding voting shares of the Trust, or with respect to a Portfolio, by vote
of a majority of the outstanding voting shares of such Portfolio, on sixty (60)
days' written notice to the Manager, or by the Manager at any time, without the
payment of any penalty, on ninety (90) days' written notice to the Trust.  This
Agreement will automatically and immediately terminate in the event of its
"assignment" (as defined in the 1940 Act).

                                  APPENDIX D

Set forth below is the Portfolio Management Agreement for the Global Strategic
Income Portfolio discussed in Proposal 4.  Allmerica Financial Investment
Management Services, Inc. ("AFIMS") has assumed the role of Allmerica Investment
Management Company, Inc. ("AIMCO") under this agreement.

                       GLOBAL STRATEGIC INCOME PORTFOLIO
                          PORTFOLIO MANAGER AGREEMENT
                       ---------------------------------

     Agreement, made this ___ day of April, 1998, among The Palladian Trust (the
"Trust"), a Massachusetts business trust; Allmerica Investment Management
Company, Inc. (the "Manager"), a Massachusetts corporation; and Allmerica Asset
Management, Inc. (the "Portfolio Manager"), a Massachusetts corporation.

     WHEREAS, the Trust is a diversified, open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"); and

     WHEREAS, the Manager and the Portfolio Manager are both registered as
investment advisers under the Investment Advisers Act of 1940; and

     WHEREAS, the Trust is authorized to issue shares of beneficial interest in
separate portfolios with each such portfolio representing interests in a
separate portfolio of securities and other assets; and

     WHEREAS, the Manager has entered into a management agreement with the
Trust, pursuant to which the Manager will provide, among other services, advice
with respect to the selection and monitoring of portfolio managers to handle the
day-to-day investment management of certain portfolios; and

     WHEREAS, the Trust and the Manager desire to retain the Portfolio Manager
to provide investment advisory services to the Global Strategic Income Portfolio
of the Trust (the "Portfolio"), and the Portfolio Manager is willing to render
such services.

     Therefore, the parties agree as follows:

     1.   Appointment.  The Trust hereby appoints the Portfolio Manager to
          -----------                                                     
provide investment advisory services with respect to the Portfolio for the
period and on the terms set forth in this Agreement, subject to the direction of
the Board of Trustees of the Trust (the "Board of Trustees").  The Portfolio
Manager accepts such appointment and agrees to render the services described
herein for the compensation provided in paragraph 13.
<PAGE>
 
                                       52

     2.   Services of the Portfolio Manager.
          --------------------------------- 

          (a) Subject to the supervision of the Board of Trustees, the Portfolio
Manager will provide day-to-day investment management of the Portfolio.  The
Portfolio Manager will provide investment research and conduct a continuous
program of evaluation, investment, sales, and reinvestment of the Portfolio's
assets by determining the securities and other investments that shall be
purchased, entered into, sold, closed, or exchanged for the Portfolio, when
these transactions should be executed, and what portion of the assets of the
Portfolio should be held in the various securities and other investments in
which it may invest.  The Portfolio Manager is hereby authorized to execute and
perform such services on behalf of the Portfolio.  To the extent permitted by
the investment policies of the Portfolio, the Portfolio Manager shall make
decisions for the Portfolio as to foreign currency matters and make
determinations as to, and execute and perform, foreign currency exchange
contracts on behalf of the Portfolio.  The Portfolio Manager will provide the
services under this Agreement in accordance with the Portfolio's investment
objective or objectives, policies, and restrictions as stated in the Trust's
registration statement under the Securities Act of 1933 and the 1940 Act as
filed with the Securities and Exchange Commission ("SEC") and amended from time
to time (the "Registration Statement").

          (b) The Portfolio Manager will use reasonable efforts to manage the
Portfolio so that it will (1) qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code, (2) comply with the diversification
requirements of Section 817(h) of the Internal Revenue Code and regulations
issued thereunder, and (3) comply with any other rules and regulations
pertaining to investment vehicles underlying variable annuity or variable life
insurance policies.  In managing the Portfolio in accordance with these
requirements, the Portfolio Manager shall be entitled to receive and act upon
advice of counsel to the Trust or counsel to the Manager.

          (c) On occasions when the Portfolio Manager deems the purchase or sale
of a security to be in the best interest of the Portfolio as well as any other
investment advisory clients, the Portfolio Manager may, to the extent permitted
by applicable laws and regulations, including, but not limited to Section 17(d)
of the 1940 Act, but shall not be obligated to, aggregate the securities to be
so sold or purchased with those of its other clients where such aggregation is
not inconsistent with the policies set forth in the Registration Statement.  In
such event, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by the Portfolio Manager in a
manner that is fair and equitable in the judgment of the Portfolio Manager in
the exercise of its fiduciary obligations to the Trust and to such other
clients.

          (d) In connection with the purchase and sale of securities for the
Portfolio, the Portfolio Manager will arrange for the transmission to the
custodian for the Trust on a daily basis, such confirmation, trade tickets, and
other documents and information as may be reasonably necessary to enable the
custodian to perform its administrative and recordkeeping responsibilities with
respect to the Portfolio.  With respect to portfolio securities to be purchased
or sold through the Depository Trust Company, the Portfolio Manager will arrange
for the automatic transmission of the confirmation of such trades to the Trust's
custodian.  The Portfolio Manager will provide to the 
<PAGE>
 
                                       53

Manager copies of the documents and information sent to the custodian and the
Depository Trust Company as requested by the Manager.
 
          (e) The Portfolio Manager will assist the custodian or recordkeeping
agent for the Trust in determining, consistent with the procedures and policies
stated in the Registration Statement, the value of any portfolio securities or
other assets of the Portfolio for which the custodian or recordkeeping agent
seeks assistance or review from the Portfolio Manager.  The Portfolio Manager
will monitor on a daily basis the determination by the custodian or
recordkeeping agent for the Trust the value of portfolio securities and other
assets of the Portfolio and the determination of net asset value of the
Portfolio.

          (f) The Portfolio Manager shall regularly report to the Board of
Trustees on the investment program for the Portfolio, and will furnish the Board
of Trustees such periodic and special reports as the Board may reasonably
request.

          (g) The Portfolio Manager shall make its officers and employees
available to the Board of Trustees, officers of the Trust, and officers of the
Manager for consultation and discussions regarding the investment program for
the Portfolio.

     3.   Broker-Dealer Selection.  The Portfolio Manager is responsible for
          -----------------------                                           
decisions to buy and sell securities and other investments for the Portfolio,
broker-dealer selection, and negotiation of brokerage commission rates.  The
Portfolio Manager's primary consideration in effecting a security transaction
will be to obtain the best execution for the Portfolio, taking into account the
factors specified in the Registration Statement.  Subject to the Registration
Statement and such policies as the Board of Trustees may determine and
consistent with Section 28(e) of the Securities Exchange Act of 1934, the
Portfolio Manager shall not be deemed to have acted unlawfully or to have
breached any duty created by this Agreement or otherwise solely by reason of its
having caused the Portfolio to pay a broker-dealer for effecting a portfolio
investment transaction in excess of the amount of commission another broker-
dealer would have charged for effecting that transaction, if the Portfolio
Manager 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-dealer, viewed in terms of either that particular transaction or the
Portfolio Manager's overall responsibilities with respect to the Portfolio and
to its other clients as to which it exercises investment discretion.

     4.   Employees.  In rendering the services required under this Agreement,
          ---------                                                           
the Portfolio Manager may, from time to time, employ such person or persons as
it believes necessary to assist it in carrying out its obligations under this
Agreement.  The Portfolio Manager shall be responsible for making reasonable
inquiries and for reasonably ensuring that no employee of the Portfolio Manager:

          (a) has been convicted, in the last ten (10) years, of any felony or
          misdemeanor arising out of conduct involving embezzlement, fraudulent
          conversion, or

          any provision of any state insurance law involving fraud, deceit, or
          knowing misrepresentation; or

          (c) has been found by any federal or state regulatory authorities,
          within the last ten (10) years, to have violated or to have
          acknowledged violation of any provisions of federal or state
          securities laws involving fraud, deceit, or knowing misrepresentation;
          or

          (d) is ineligible by reason of Section 9 of the 1940 Act to serve as
          an employee of an investment adviser to an investment company.

     5.   Conformity with Applicable Law.  The Portfolio Manager, in the

thereof, shall be free to render similar services to other investment companies
and other clients and to engage in other activities, so long as its services
hereunder are not impaired thereby.

     7.   Documents.  The Trust has delivered copies of each of the following
          ---------

Manager further agrees that all records which it maintains for the Trust are the
property of the Trust and it will promptly surrender any of such records upon
request.

     9.   Disclosure by Portfolio Manager.  The Portfolio Manager will not

     13.  Compensation.
          ------------ 

          (a) For the services provided and the expenses borne by the Portfolio
Manager pursuant to this Agreement, the Trust will pay the Portfolio Manager 80%
of the Initial Monthly Advisory Fee or the Monthly Advisory Fee, as those terms
are defined in this paragraph, whichever is applicable.

          (b) For the period beginning with the effective date of this Agreement
and ending with the last day of the twelfth full calendar month thereafter, the
Portfolio will pay at the end of each month, an advisory fee calculated at an
annual rate of 0.80% of the Portfolio's average daily net assets (the "Initial
Monthly Advisory Fee").

          (c) For the period beginning with the first day of the thirteenth full
calendar month after the effective date of this Agreement and continuing through
the remainder of the term of this Agreement, the Portfolio will pay at the end
of each month, an advisory fee (the "Monthly Advisory Fee").  The Monthly
Advisory Fee equals the Basic Fee (as defined in paragraph 13(d) below) plus the
Incentive Fee (as defined in paragraph 13(e) below) and adjusted, if so
required, by paragraph 13(h) below.

          (d) The Basic Fee equals one-twelfth of 2% multiplied by the
Portfolio's average daily net assets for the previous 12 months (including the
month for which the fee is being calculated).

          (e) The Incentive Fee equals:  (i) one-twelfth of the Annual Incentive
Fee set forth in the chart below based on the difference between the Performance
of the Portfolio and the Performance of the Benchmark, as those terms are
defined in paragraphs 13(f) and 13(g) below; (ii) multiplied by the Portfolio's
average daily net assets for the previous 12 months (including the month for
which the fee is being calculated).

          (f) The Performance of the Portfolio will be calculated by first
determining the change in the Portfolio's net asset value per share during the
previous twelve months (including the month for which the fee is being computed)
assuming the reinvestment of distributions during that period, and then
expressing this amount as a percentage of the net asset value per share at the
beginning of the period.  Net asset value per share is calculated by dividing
the value of the securities held by the Portfolio plus any cash or other assets
minus all liabilities including accrued advisory fees and the other expenses, by
the total number of shares outstanding at the time.  The Performance of the
Portfolios shall be calculated in accordance with SEC rules.

          (g) The Performance of the Benchmark will be calculated by first
determining the change in the level of the Benchmark during the previous twelve
months (including the month for which the fee is being computed) plus the value
of any cash dividends or distributions made by the companies whose securities
comprise the Benchmark accumulated to the end of the period, and then expressing
this amount as a percentage of the Benchmark at the beginning of the period.
The Performance of the Benchmark shall be calculated in accordance with SEC
rules.  The Benchmark is the Lehman Brothers Aggregate Bond Index.  If the
Benchmark ceases to be published, changes in any material respect or otherwise
becomes impracticable to use for purposes of the Incentive Fee, the Monthly
Advisory Fee will equal the Basic Fee (with no incentive adjustment) until such
time as the Board of Trustees approves a substitute Benchmark.

          (h) Notwithstanding paragraphs 13(a)-13(g) above, if the Performance
of a Portfolio (minus payment of all expenses, including the Basic Fee and any
Incentive Fee) is negative and does not exceed the Performance of the Benchmark
by six percentage points, then the Monthly 

<PAGE>

                                       59

Advisory Fee will equal zero. Notwithstanding paragraphs 13(a)-13(g) above, if
the Performance of a Portfolio (minus payment of all expenses, including the
Basic Fee and any Incentive Fee) is negative, exceeds the Performance of the
Benchmark by six percentage points, but does not exceed the Performance of the
Benchmark by twelve percentage points, then the Monthly Advisory Fee will not be
greater than one-twelfth of 1% of the Portfolio's average daily net assets for
the previous 12 months (including the month for which the fee is being
calculated). Notwithstanding paragraphs 13(a)-13(g) above, if the Performance of
a Portfolio (minus payment of all expenses, including the Basic Fee and any
Incentive Fee) is negative and exceeds the Performance of the Benchmark by
twelve percentage points, then the Monthly Advisory Fee will not be greater than
one-twelfth of 2% of the Portfolio's average daily net assets for the previous
12 months (including the month for which the fee is being calculated).

     14.  Liability and Indemnification.  The Portfolio Manager, the Manager and
          -----------------------------                                         
the Trust each may rely on information reasonably believed by it to be accurate
and reliable.  The Portfolio Manager shall not be liable to the Trust or its
shareholders for any loss suffered by the Trust as the result of any negligent
act or error of judgment of the Portfolio Manager in connection with the matters
to which this Agreement relates, except a loss resulting from a breach by the
Portfolio Manager of its fiduciary duty with respect to the receipt of
compensation for services (in which case any award of damages shall be limited
to the period and the amount set forth in Section 36(b)(3) of the 1940 Act) or
loss resulting from willful misfeasance, bad faith or gross negligence on its
part in the performance of its duties or from reckless disregard by it of its
obligations and duties under this Agreement.  The Trust shall indemnify the
Portfolio Manager and hold it harmless from all cost, damage and expense,
including reasonable expenses for legal counsel, incurred by the Portfolio
Manager resulting from actions for which it is relieved of responsibility by
this paragraph.  The Portfolio Manager shall indemnify the Trust and hold it
harmless from all cost, damage and expense, including reasonable expenses for
legal counsel, incurred by the Trust resulting from (i) a breach by the
Portfolio Manager of its fiduciary duty with respect to compensation for
services paid by the Trust (in which case any award of damages shall be limited
to the period and the amount set forth in Section 36(b)(3) of the 1940 Act);
(ii) willful misfeasance, bad faith or gross negligence by the Portfolio Manager
in the performance of its duties under this Agreement; or (iii) reckless
disregard by the Portfolio Manager of its obligations and duties under this
Agreement.

     15.  Continuation and Termination.  This Agreement shall take effect on the
          ----------------------------                                          
date first written above, and shall continue in effect, unless sooner terminated
as provided herein, for 119 days thereafter, and provided that the Agreement is
approved by a majority of the outstanding voting shares of the Portfolio by the
end of such 119th day, shall continue for two years from the date of this
Agreement and shall continue from year to year thereafter so long as such
continuance is specifically approved at least annually (i) by the vote of a
majority of the Board of Trustees; or (ii) by vote of a majority of the
outstanding voting shares of the Portfolio; provided, further, in either event
that continuance is also approved by the vote of a majority of the Board of
Trustees who are not parties to this Agreement or "interested persons" (as
defined in the 1940 Act) of the Trust, the Manager or the Portfolio Manager cast
in person at a meeting called for the purpose of voting on such approval.  This
Agreement may be terminated (i) by the Trust at any time, without the payment 

<PAGE>

                                       60

of any penalty, by vote of a majority of the entire Board of Trustees or by a
vote of a majority of the outstanding voting shares of the Portfolio, on sixty
(60) days' written notice to the Manager and the Portfolio Manager, (ii) by the
Manager at any time, without the payment of any penalty, on ninety (90) days'
written notice to the Trust and the Portfolio Manager, or (iii) by the Portfolio
Manager at any time, without the payment of any penalty, on ninety (90) days'
written notice to the Trust and the Manager. This Agreement will automatically
and immediately terminate in the event of its "assignment" (as defined in the
1940 Act).

     16.  Independent Contractor.  The Portfolio Manager shall for all purposes
