being hereinafter called the "Trustees") and by the holders of shares of
beneficial interest issued and to be issued hereunder hereinafter provided, and

                              W I T N E S S E T H

     WHEREAS, the Trustees desire to form a trust fund under the laws of the
Commonwealth of Massachusetts for the investment and reinvestment of funds
contributed thereto; and

     WHEREAS, it is proposed that the beneficial interest in the trust assets be
divided into transferable shares of beneficial interest, which may, at the
discretion of the Trustees, be divided into separate series and classes as
hereinafter provided;

     NOW, THEREFORE, the Trustees hereby declare that they will hold in trust
all money and property contributed to the trust fund to manage and dispose of
the same for the benefit of the holders from time to time of the shares of
beneficial interest issued hereunder and subject to the provisions hereof, to
wit:

                                   ARTICLE I

                                   The Trust

     Section 1.1  Name.  The name of the trust created hereby (the "Trust"),
which term shall be deemed to include any series of the Trust when the context
requires, shall be "PIMCO Advisors Institutional Funds", and so far as may be
practicable the Trustees shall conduct the activities of the Trust, execute all
documents and sue or be sued under that name, which name (and the word "Trust"
wherever hereinafter used) shall refer to the Trustees as Trustees, and not
individually, and shall not refer to the officers, agents, employees or
shareholders of the Trust or any Series thereof.  Each Series of the Trust which
shall be established and designated by the Trustees pursuant to Section 6.2
shall conduct its activities under such name as the Trustees

                                       5

shall determine and set forth in the instrument establishing such Series.
Should the Trustees determine that the use of the name of the Trust or any
Series is not advisable, they may select such other name for the Trust or such
Series as they deem proper and the Trust or such Series may conduct its
activities under such other name.  Any name change shall be effective upon the
execution by a majority of the then Trustees of an instrument setting forth the
new name.  Any such instrument shall have the status of an amendment to this
Agreement and Declaration of Trust.

Trust, the following terms shall have the following meanings:

to refer to the Declaration rather than the article or section in which such
words appear.

          "Fundamental Policies" shall mean the investment objective for each
Series and the investment restrictions set forth in the registration statement
for the Trust on Form N-1A and designated as fundamental policies therein.

effective Statement of Additional Information of any Series of the Trust under
the Trust's registration statement filed pursuant to the Securities Act of 1933,
as amended.

they shall continue in office in accordance with the terms hereof, and all other
persons who at the time in question have been duly elected or appointed and have
qualified as Trustees in accordance with the provisions hereof and are then in
office, and each such person is herein referred to as the "Trustee", and
reference in this Declaration to a Trustee or Trustees shall refer to such
person or persons in their capacity as Trustees hereunder.

          "Trust Property" shall mean as of any particular time any and all
property, real or personal, tangible or intangible, which at such time is owned
or held by or for the account of the Trust, any Series thereof or the Trustees.

                                    Trustees

     Section 2.1  Management of the Trust.  The business and affairs of the
Trust shall be managed by the Trustees, and they shall have all powers necessary
and desirable to carry out that responsibility.  The Trustees named herein (or
their successors appointed hereunder) shall serve until the election of Trustees
at the first meeting of Shareholders of the Trust.

     Section 2.2  Election of Trustees.  Except for the Trustees named herein
and those Trustees designated by such Trustees prior to the issuance of Shares,
or appointed to fill vacancies pursuant to Section 2.4 hereof, the Shareholders
of the Trust shall elect Trustees at Shareholder meetings called for that
purpose.  The Trustees need not be elected annually or at regular intervals.
Except as provided in Section 9.2, the Trustees shall not be required to call a
meeting of Shareholders for the purpose of electing Trustees, provided, however,
that in the event that at any time, other than the time preceding the first
meeting of Shareholders for the purpose of electing Trustees, less than a
majority of the Trustees holding office at that time were elected by the
Shareholders, a meeting of the Shareholders for the

                                       7
<PAGE>
 
purpose of electing Trustees shall be held promptly and in any event within 60
days (unless the Commission shall by order extend such period).  No election of
a Trustee shall become effective, however, until the person elected shall have
accepted such election and agreed in writing to be bound by the terms of this
Declaration.  If re-elected, a Trustee may succeed himself.  Trustees need not
own shares.

     Section 2.3  Term of Office of Trustees.  A Trustee duly appointed or
elected hereunder shall hold office until the occurrence of any of the
following:  (a) the Trustee may resign his trust by written instrument signed by
him and delivered to the other Trustees, which shall take effect upon such
delivery or upon such later date as is specified therein; (b) the Trustee may be
removed at any time by written instrument signed by at least two-thirds of the
number of Trustees prior to such removal, specifying the date when such removal
shall become effective; (c) the Trustee who requests in writing to be retired or
who has become mentally or physically incapacitated may be retired by written
instrument signed by a majority of the other Trustees, specifying the date of
his retirement; and (d) the Trustee may be removed at any meeting of
Shareholders of the Trust by a vote of two-thirds of the outstanding Shares or
by a written declaration executed, without a meeting, by the holders of not less
than two-thirds of the outstanding Shares.  A meeting for the purpose of
considering the removal of a person serving as Trustee shall be called by the
Trustees if requested in writing to do so by the holders (which for purposes of
this provision and only this provision shall be the persons having a voting
interest in the shares of the Trust) of not less than 10% of the outstanding
shares of the Trust.

     Section 2.4  Termination of Service and Appointment of Trustees.  In case
of the death, resignation, retirement, removal or mental or physical incapacity
of any of the Trustees, or in case a vacancy shall, by reason of an increase in
number, or for any other reason, exist, the remaining Trustees may (but need not
unless required by the 1940 Act, so long as there are at least two remaining
Trustees) fill such vacancy by appointing for the remaining term of the
predecessor Trustee such other person as they in their discretion shall see fit.
Such appointment shall be effective upon the signing of a written instrument by
a majority of the Trustees in office and the written acceptance of this
Declaration by the appointee.  An appointment of a Trustee may be made by the
Trustees then in office in anticipation of a vacancy to occur by reason of
retirement, resignation or increase in number of Trustees effective at a later
date, provided that said appointment shall become effective only at or after the
effective date of said retirement, resignation or increase in number of Trustees
and the written acceptance of this Declaration by the appointee.  As soon as any
Trustee so appointed shall have accepted this Trust, the trust estate shall vest
in the new Trustee or Trustees, together with the continuing Trustees, without
any further act or conveyance, and he shall be deemed a

                                       8
<PAGE>
 
Trustee hereunder.  Any appointment authorized by this Section 2.4 is subject to
the provisions of Section 16(a) of the 1940 Act.

     Section 2.5  Temporary Absence of Trustee.  Any Trustee may, by power of
attorney, delegate his power for a period not exceeding six months at any one
time to any other Trustee or Trustees, provided that in no case shall less than
two of the Trustees personally exercise the power hereunder except as herein
otherwise expressly provided.

     Section 2.6  Number of Trustees.  The number of Trustees serving hereunder
at any time shall be determined by the Trustees themselves, but once Shares have
been issued shall not be less than two (2) or more than fifteen (15).

     Section 2.7  Effect of Death, Resignation, etc. of a Trustee.  The death,
resignation, retirement, removal, or mental or physical incapacity of the
Trustees, or any one of them, shall not operate to annul or terminate the Trust
or any Series hereunder or to revoke or terminate any existing agency or
contract created pursuant to the terms of this Declaration, and until such
vacancy is filled, the Trustees in office, regardless of their number, shall
have all of the powers granted to the Trustees and shall discharge all the
duties imposed upon them by this Declaration.

     Section 2.8  No Accounting.  Except to the extent required by the 1940 Act
or under circumstances which would justify his removal for cause, no person
ceasing to be a Trustee as a result of his death, resignation, retirement,
removal or incapacity (nor the estate of any such person) shall be required to
make an accounting to the shareholders or remaining Trustees upon such
cessation.

     Section 2.9  Ownership of the Trust.  The assets of the Trust shall be held
separate and apart from any assets now or hereafter held in any capacity other
than as Trustee hereunder by the Trustees or by any successor Trustees.  All of
the assets of the Trust shall at all times be considered as vested in the
Trustees.  No Shareholder shall be deemed to have a severable ownership in any
individual asset of the Trust or any right of partition or possession thereof,
but each Shareholder shall have a proportionate undivided beneficial interest in
the Trust.

                                  ARTICLE III

                               Powers of Trustees

     Section 3.1  General.  The Trustees in all instances shall act as
principals, and are and shall be free from the control of the Shareholders.  The
Trustees shall have full power and authority to do any and all acts and to make
and execute any and all contracts and instruments that they may consider
necessary or

                                       9
<PAGE>
 
appropriate in connection with the management of the Trust.  The Trustees shall
not be bound or limited by present or future laws or customs with regard to
investment by trustees or fiduciaries, but shall have full authority and
absolute power and control over the Trust Property and business of the Trust to
the same extent as if the Trustees were the sole owners of the Trust Property
and business in their own right, including such authority, power and control to
do all acts and things as they, in their uncontrolled discretion, shall deem
proper to accomplish the purposes of this Trust.  The enumeration of any
specific power herein shall not be construed as limiting the aforesaid powers.

     Section 3.2  Investments.  The Trustees shall have power, subject to the
Fundamental Policies, to:

          (a)  conduct, operate and carry on the business of an investment
               company;

               instruments, bank obligations, evidences of indebtedness,
               privately placed debt securities, certificates of deposit or
               indebtedness, commercial paper, repurchase agreements, reverse
               repurchase agreements, firm commitment agreements and "when-
               issued" securities and other securities, including, without
               limitation, those issued, guaranteed, or sponsored by any state,
               territory or possession of the United States and the District of
               Columbia and their political subdivisions, agencies and
               instrumentalities, or by the United States Government or its
               agencies or instrumentalities, or international
               instrumentalities, or by any bank, savings institution,
               corporation or other business entity organized under the laws of
               the United States and, to the extent provided in the Prospectus
               and not prohibited by the Fundamental Policies of the Trust,
               foreign securities of issuers or governments organized under
               foreign laws, foreign currency transactions and options on
               foreign currency transactions, and

                                       10

               other assets; and to exercise any and all rights, powers and
               privileges of ownership or interest in respect of any and all
               such investments of every kind and description, with power to
               designate one or more persons, firms, associations or
               corporations to exercise any of said rights, powers and
               privileges in respect of any of said instruments; and the
               Trustees shall be deemed to have the foregoing powers with
               respect to any additional securities or other assets in which any
               Series of the Trust may invest should the investment policies set
               forth in the Prospectus or the Fundamental Policies be amended.

     The Trustees shall not be limited to investing in obligations maturing
before the possible termination of the Trust or any Series.

     Section 3.3  Legal Title.  Legal title to all the Trust Property shall be
vested in the Trustees as joint tenants except that the Trustees shall have
power to cause legal title to any Trust Property to be held by or in the name of
one or more of the Trustees, or in the name of the Trust or any Series thereof,
or in the name of any other Person as nominee, on such terms as the Trustees may
determine, provided that the interest of the Trust or any Series thereof is
appropriately protected.

     Section 3.4  Issuance and Repurchase of Securities.  The Trustees shall
have the power to issue, sell, repurchase, redeem, retire, cancel, acquire,
hold, resell, reissue, dispose of, transfer, and otherwise deal in, Shares,
including shares in fractional denominations, and, subject to the more detailed
provisions set forth in Articles VII and VIII, to apply to any such repurchase,
redemption, retirement, cancellation or acquisition of Shares any funds or
property of the applicable Series of the Trust whether capital or surplus or
otherwise, to the full extent now or hereafter permitted by the laws of the
Commonwealth of Massachusetts governing business corporations.

     Section 3.5  Borrow Money.  Subject to the Fundamental Policies, the
Trustees shall have power to borrow money or otherwise obtain credit and to
secure the same by mortgaging, pledging or otherwise subjecting as security the

securities, and to endorse, guarantee or undertake the performance of any
obligation, contract or engagement of any other person, form, association or
corporation.

     Section 3.6  Officers; Delegation; Committees.  The Trustees may, as they
consider appropriate, elect and remove officers and appoint and terminate agents
and consultants and hire and terminate employees, any one or more of the
foregoing of whom may be a Trustee and may provide for the compensation of all

continuing exclusive authority over the management of the Trust and the Trust
Property, to delegate from time to time to such of their number or to officers,
employees or agents of the Trust the doing of such things and the execution of
such instruments either in the name of the Trust or the names of the Trustees or
otherwise as the Trustees may deem expedient.  The Trustees may appoint from
their number and terminate any one or more committees consisting of two or more
Trustees, including without implied limitation an Executive Committee which may,
when the Trustees are not in session and subject to the 1940 Act, exercise some
or all of the powers and authority of the Trustees as the Trustees may
determine.

     Section 3.7  Collection and Payment.  The Trustees shall have power to

business of the Trust.

agents, investment advisers, distributors, selected dealers or independent
contractors of the Trust or any Series or Class thereof against all claims
arising by reason of holding any such position or by reason of any action taken
or omitted by any such Person in such capacity, whether or not constituting
negligence, or whether or not the Trust would have the power to indemnify such
Person against such liability; (d) establish pension, profit-sharing, share

not herein specifically mentioned.  Any determination as to what is in the
interests of the Trust or any Series or Class thereof made by the Trustees in
good faith shall be conclusive.  In construing the provisions of this
Declaration, the presumption shall be in favor of a grant of power to the
Trustees.  The Trustees will not be required to obtain any court

                                       13
<PAGE>

bond or other security for the performance of any of his duties hereunder.

                                   ARTICLE IV

                      Advisory, Administrative, Management
                         and Distribution Arrangements

     Section 4.1  Advisory and Management Arrangements.  Subject to a Majority
Shareholder Vote, if required by law, of the applicable Series, the Trustees may
in their discretion from time to time enter into advisory, administrative or
management contracts whereby the other party to such contract shall undertake to
furnish to the Trustees such advisory, administrative and management services,
with respect to a Series as the Trustees shall from time to time consider
desirable and all upon such terms and conditions as the Trustees may in their
discretion determine.  Subject to a Majority Shareholder Vote if required by
law, the investment adviser may engage one or more firms to serve as Portfolio
Manager to a Series pursuant to a sub-investment advisory contract in which the
Portfolio Manager makes all determinations with respect to the purchase and sale
of portfolio securities and places, in the names of the Series all orders for
execution of the Series' portfolio transactions upon such terms and conditions
and for such compensation as the Trustees may in their discretion approve.  A
Portfolio Manager may, in turn, engage its own sub-adviser in managing a
particular Series.  Notwithstanding any provisions of this Declaration, the
Trustees may authorize any adviser, portfolio manager, administrator or manager
(subject to such general or specific instructions as the Trustees may from time
to time adopt) to effect purchases, sales, loans or exchanges of portfolio
securities of any Series of the Trust on behalf of the Trustees or may authorize
any officer, employee or Trustee to effect such purchases, sales, loans or
exchanges pursuant to recommendations of any such adviser, portfolio manager,
administrator or manager (and all without further action by the Trustees).  Any
such purchases, sales, loans or exchanges shall be deemed to have been
authorized by all of the Trustees.

     Section 4.2  Distribution Arrangements.  The Trustees may in their
discretion from time to time enter into a contract, providing for the sale of
the Shares of the Trust or any Series or Class of the Trust, whereby the Trust
may either agree to sell the Shares to the other party to the contract or
appoint such other party as its sales agent for such Shares.  In either case,
the contract shall be on such terms and conditions as the Trustees may in their
discretion determine to be not inconsistent with the provisions of this Article
IV or the By-laws; and such contract may also provide for the repurchase or sale
of Shares by such other party as principal or as agent of the Trust and may
provide that such other party may enter into selected dealer agreements with
registered securities dealers to further the

                                       14
<PAGE>
 
purpose of the distribution or repurchase of the Shares.  The Trustees may adopt
a Distribution Plan pursuant to Rule 12b-1 of the 1940 Act and may authorize the
Trust to make payments from its assets pursuant to such Plan.

     Section 4.3  Parties to Contract.  Any contract of the character described
in Sections 4.1 and 4.2 of this Article IV hereof may be entered into with any
corporation, firm, trust or association, although one or more of the Trustees or
officers of the Trust may be an officer, director, Trustee, shareholder or
member of such other party to the contract, and no such contract shall be
invalidated or rendered voidable by reason of the existence of any such
relationship, nor shall any person holding such relationship be liable merely by
reason of such relationship for any loss or expense to the Trust under or by
reason of said contract or accountable for any profit realized directly or
indirectly therefrom, provided that the contract when entered into was
reasonable and fair and not inconsistent with the provisions of this Article IV
or the By-laws.  The same person (including a firm, corporation, trust or
association) may be the other party to contracts entered into pursuant to
Sections 4.1 and 4.2 above, and any individual may be financially interested or
otherwise affiliated with persons who are parties to any or all of the contracts
mentioned in this Section 4.3.

     Section 4.4  Provisions and Amendments.  Any contract under which the other
party agrees to serve as investment adviser or principal underwriter for the
Fund or any Series or Class thereof, which is entered into pursuant to Sections
4.1 and 4.2 of this Article IV shall be consistent with and subject to the
requirements of Section 15 of the 1940 Act with respect to its continuance in
effect, its termination, and the method of authorization and approval of such
contract or renewal thereof, and no amendment to any contract entered into
pursuant to Section 4.1 shall be effective unless consented to by a Majority
Shareholder Vote of the applicable Series if required by law.

                                   ARTICLE V

         Limitations of Liability of Shareholders, Trustees and Others

     Section 5.1  Trustees, Shareholders, etc. Not Personally Liable; Notice.
All persons extending credit to, contracting with or having any claim against
the Trust shall look only to the assets of the Series with which such person
dealt for payment under such credit, contract or claim; and neither the
Shareholders of any Series nor the Trustees, nor any of the Trust's officers,
employees or agents, whether past, present or future, nor any other Series shall
be personally liable therefor.  Every note, bond, contract, instrument,
certificate or undertaking and every other act or thing whatsoever executed or
done by or on behalf of the Trust, any Series or Class, or the Trustees or any
of them in connection with the Trust shall be conclusively deemed to have been
executed or done only by or for the Trust (or the

                                       15
<PAGE>
 
Series or Class) or the Trustees and not personally.  Nothing in this
Declaration shall protect any Trustee or officer against any liability to the
Trust or the Shareholders to which such Trustee or officer would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of the office of
Trustee or of such officer.

     Every note, bond, contract, instrument, certificate, share or undertaking
made or issued by the Trustees or by any officers or officer shall give notice
that this Declaration is on file with the Secretary of The Commonwealth of
Massachusetts and shall recite to the effect that the same was executed or made
by or on behalf of the Trust or by them as Trustees or Trustee or as officers or
officer and not individually, and that the obligations of such bond, contract,
instrument, certificate, share or undertaking are not binding upon any of them
or the Shareholders individually but are binding only upon the assets and
property of the Trust, or the particular Series in question, as the case may be,
but the omission thereof shall not operate to bind any Trustees or Trustee or
officers or officer or Shareholders or Shareholder individually.

     Section 5.2  Trustee's Good Faith Action; Expert Advice; No Bond or Surety.
The exercise by the Trustees of their powers and discretion hereunder shall be
binding upon everyone interested.  A Trustee shall be liable for his own willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of the office of Trustee, and for nothing else, and
shall not be liable for errors of judgment or mistakes of fact or law.  Subject
to the foregoing, (a) the Trustees shall not be responsible or liable in any
event for any neglect or wrongdoing of any officer, agent, employee, consultant,
adviser, administrator, distributor or principal underwriter, custodian or
transfer, dividend disbursing, Shareholder servicing or accounting agent of the
Trust, nor shall any Trustee be responsible for the act or omission of any other
Trustee; (b) the Trustees may take advice of counsel or other experts with
respect to the meaning and operation of this Declaration and their duties as
Trustees, and shall be under no liability for any act or omission in accordance
with such advice or for failing to follow such advice; and (c) in discharging
their duties, the Trustees, when acting in good faith, shall be entitled to rely
upon the books of account of the Trust and upon written reports made to the
Trustees by any officer appointed by them, any independent public accountant,
and (with respect to the subject matter of the contract involved) any officer,
partner or responsible employee of any adviser, administrator, manager,
distributor, selected dealer, appraiser or other expert, consultant or agent.
The Trustees as such shall not be required to give any bond or surety or any
other security for the performance of their duties.

     Section 5.3  Indemnification of Shareholders.  In case any Shareholder (or
former Shareholder) of any Series of the Trust

                                       16
<PAGE>
 
shall be charged or held to be personally liable for any obligation or liability
of the Trust solely by reason of being or having been a Shareholder and not
because of such Shareholder's acts or omissions or for some other reason, said
Series (upon proper and timely request by the Shareholder) shall assume the
defense against such charge and satisfy any judgment thereon, and the
Shareholder or former Shareholder (or his heirs, executors, administrators or
other legal representatives or in the case of a corporation or other entity, its
corporate or other general successor) shall be entitled out of the assets of
said Series' estate to be held harmless from and indemnified against all loss
and expense arising from such liability.

     Section 5.4  Indemnification of Trustees, Officers, etc.  The Trust shall
indemnify (from the assets of the Trust or Series in question) each of its
Trustees and officers (including persons who serve at the Trust's request as
directors, officers or trustees of another organization in which the Trust has
any interest as a shareholder, creditor or otherwise) [hereinafter referred to
as a "Covered Person"] against all liabilities, including but not limited to
amounts paid in satisfaction of judgments, in compromise or as fines and
penalties, and expenses, including reasonable accountants' and counsel fees,
incurred by any Covered Person in connection with the defense or disposition of
any action, suit or other proceeding, whether civil or criminal, before any
court or administrative or legislative body, in which such Covered Person may be
or may have been involved as a party or otherwise or with which such person may
be or may have been threatened, while in office or thereafter, by reason of
being or having been such a Trustee or officer, director or trustee, except with
respect to any matter as to which it has been determined that such Covered
Person (i) did not act in good faith in the reasonable belief that such Covered
Person's action was in or not opposed to the best interests of the Trust or (ii)
had acted with willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such Covered Person's office
(either and both of the conduct described in (i) and (ii) being referred to
hereafter as "Disabling Conduct").  A determination that the Covered Person is
entitled to indemnification may be made by (i) a final decision on the merits by
a court or other body before whom the proceeding was brought that the person to
be indemnified was not liable by reason of Disabling Conduct, (ii) dismissal of
a court action or an administrative proceeding against a Covered Person for
insufficiency of evidence of Disabling Conduct, or (iii) a reasonable
determination, based upon a review of the facts, that the indemnitee was not
liable by reason of Disabling Conduct by (a) a vote of a majority of a quorum of
Trustees who are neither "interested persons" of the Trust as defined in section
2(a)(19) of the 1940 Act nor parties to the proceeding, or (b) an independent
legal counsel in a written opinion.  Expenses, including accountants' and
counsel fees so incurred by any such Covered Person (but excluding amounts paid
in satisfaction of judgments, in compromise or as fines or penalties), may be
paid from time to time by

                                       17
<PAGE>
 
the Series in question in advance of the final disposition of any such action,
suit or proceeding, provided that the Covered Person shall have undertaken to
repay the amounts so paid to the Series in question if it is ultimately
determined that indemnification of such expenses is not authorized under this
Article V and (i) the Covered Person shall have provided security for such
undertaking, (ii) the Trust shall be insured against losses arising by reason of
any lawful advances, or (iii) a majority of a quorum of the disinterested
Trustees who are not a party to the proceeding, or an independent legal counsel
in a written opinion, shall have determined, based on a review of readily
available facts (as opposed to a full trial-type inquiry), that there is reason
to believe that the Covered Person ultimately will be found entitled to
indemnification.

     Section 5.5  Compromise Payment.  As to any matter disposed of by a
compromise payment by any such Covered Person referred to in Section 5.4,
pursuant to a consent decree or otherwise, no such indemnification either for
said payment or for any other expenses shall be provided unless such
indemnification shall be approved (a) by a majority of the disinterested
Trustees who are not parties to the proceeding or (b) by an independent legal
counsel in a written opinion.  Approval by the Trustees pursuant to clause (a)
or by independent legal counsel pursuant to clause (b) shall not prevent the
recovery from any Covered Person of any amount paid to such Covered Person in
accordance with any of such clauses as indemnification if such Covered Person is
subsequently adjudicated by a court of competent jurisdiction not to have acted
in good faith in the reasonable belief that such Covered Person's action was in
or not opposed to the best interests of the Trust or to have been liable to the
Trust or its Shareholders by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office.

     Section 5.6  Indemnification Not Exclusive, etc.  The right of
indemnification provided by this Article V shall not be exclusive of or affect
any other rights to which any such Covered Person may be entitled.  As used in
this Article V, "Covered Person" shall include such person's heirs, executors
and administrators; "interested Covered Person" is one against whom the action,
suit or other proceeding in question or another action, suit or other proceeding
on the same or similar grounds is then or has been pending or threatened, and a
"disinterested" person is a person against whom none of such actions, suits or
other proceedings or another action, suit or other proceeding on the same or
similar grounds is then or has been pending or threatened.  Nothing contained in
this Article shall affect any rights to indemnification to which personnel of
the Trust, other than Trustees and officers, and other persons may be entitled
by contract or otherwise under law, nor the power of the Trust to purchase and
maintain liability insurance on behalf of any such person.

     Section 5.7  Liability of Third Persons Dealing with Trustees.  No person
dealing with the Trustees shall be bound to make any inquiry concerning the
validity of any transaction made or to be made by the Trustees or to see to the
application of any payments made or property transferred to the Trust or upon
its order.

                                   ARTICLE VI

                         Shares of Beneficial Interest

     Section 6.1  Beneficial Interest.  The interest of the beneficiaries
hereunder shall be divided into transferable shares of beneficial interest which
may be divided into one or more separate and distinct series, or classes
thereof, as the Trustees from time to time create and establish.  Each share
shall have a par value of $.001.  The number of such shares of beneficial
interest authorized hereunder is unlimited.  All Shares issued hereunder
including, without limitation, Shares issued in connection with a dividend in
Shares or a split of Shares, shall be fully paid and nonassessable.

     Section 6.2  Series Designation.  The Trustees, in their discretion from
time to time, may authorize the division of Shares into additional Series, each
additional Series relating to a separate portfolio of investments.  The
following Series are hereby established and designated:

          Utility Stock Fund
          NFJ Equity Income Fund
          NFJ Diversified Low P/E Fund
          NFJ Small Cap Value Fund

          International Active Variable Fund

These Series shall be the only Series until additional Series are established
and designated by the Trustees.  Different Series may be established and
designated and variations in the relative rights and preferences as between the
different Series shall be fixed and determined by the Trustees; provided that
all Shares shall be identical except that there may be variations between
different Series as to investment policies, securities portfolios, purchase
price, determination of net asset value, the price, terms and manner of
redemption, special and relative rights as to dividends and on liquidation,
conversion rights, and conditions under which the several Series shall have
separate voting rights.  All references to Shares in this Declaration shall be
deemed to be shares of any or all Series as the context may require.

     The following provisions shall be applicable to all Series:

          (a)  The number of Shares of each Series that may be issued shall be
               unlimited.  The Trustees may classify or reclassify any unissued
               Shares or any Shares previously issued and required of any Series
               into one or more Series that may be established and designated
               from time to time.  The Trustees may hold as treasury Shares (of
               the same or some other Series), reissue for such consideration
               and on such terms as they may determine, or cancel any Shares of
               any Series reacquired by the Trust at their discretion from time
               to time.

          (b)  The power of the Trustees to invest and reinvest the Trust
               Property of each Series that has been or that may be established
               shall be governed by Section 3.2 of this Declaration.

          (c)  All consideration received by the Trust for the issue or sale of
               Shares of a particular Series, together with all assets in which
               such consideration is invested or reinvested, all income,
               earnings, profits, and proceeds thereof, including any proceeds
               derived from the sale, exchange or liquidation of such assets,
               and any funds or payments derived from any reinvestment of such
               proceeds in whatever form the same may be, shall irrevocably
               belong to that Series for all purposes, subject only to the
               rights of creditors, and shall be so recorded upon the books of
               account of the Trust.  In the event that there are any assets,
               income, earnings, profits and proceeds thereof, funds or payments
               which are not readily identifiable as belonging to any particular
               Series, the Trustees shall allocate them among any one or more of
               the Series established and designated from time to

                                       20
<PAGE>
 
               time in such manner and on such basis as they, in their sole
               discretion, deem fair and equitable.  Each such allocation by the
               Trustees shall be conclusive and binding upon the Shareholders of
               all Series for all purposes.

          (d)  The assets belonging to each particular Series shall be charged
               with the liabilities of the Trust in respect of that Series and
               all expenses, costs, charges and reserves attributable to that
               Series, and any general liabilities, expenses, costs, charges or
               reserves of the Trust which are not readily identifiable as
               belonging to any particular Series shall be allocated and charged
               by the Trustees to and among any one or more of the Series
               established and designated from time to time in such manner and
               on such basis as the Trustees in their sole discretion deem fair
               and equitable.  Each allocation of liabilities, expenses, costs,
               charges and reserves by the Trustees shall be conclusive and
               binding upon the holders of all Series for all purposes.  The
               Trustees shall have full discretion, to the extent not
               inconsistent with the 1940 Act, to determine which items shall be
               treated as income and which items as capital; and each such
               determination and allocation shall be conclusive and binding upon
               the Shareholders.

          (e)  The power of the Trustees to pay dividends and make distributions
               with respect to any one or more Series shall be governed by
               Section 9.2 of this Trust.  Dividends and distributions on Shares
               of a particular Series may be paid with such frequency as the
               Trustees may determine, which may be daily or otherwise, pursuant
               to a standing resolution or resolutions adopted only once or with
               such frequency as the Trustees may determine, to the holders of
               Shares of that Series, from such of the income and capital gains,
               accrued liabilities belonging to that Series.  All dividends and
               distributions on Shares of a particular Series shall be
               distributed pro rata to the holders of that Series in proportion
               to the number of Shares of that Series held by such holders at
               the date and time of record established for the payment of such
               dividends or distributions.

     The establishment and designation of any additional Series of Shares shall
be effective upon the execution by a majority of the then Trustees of any
instrument setting forth the establishment and designation of such Series.  Such
instrument shall also set forth any rights and preferences of such Series which
are in addition to the rights and preferences of Shares set forth in this
Declaration.  The Trustees may by an instrument executed by

                                       21
<PAGE>
 
a majority of their number abolish a Series and the establishment and
designation thereof.  Each instrument referred to in this paragraph shall have
the status of an amendment to this Declaration.

     Section 6.2.1  Class Designation.  The Trustees, in their discretion, may
authorize the division of the Shares of the Trust or the Shares of any Series,
into two or more Classes, and the different Classes shall be established and
designated, and the variations in the relative rights and preferences as between
the different Classes shall be fixed and determined, by the Trustees; provided,
that all Shares of the Trust or of any Series shall be identical to all other
Shares of the Trust or the same Series, as the case may be, except that there
may be variations between different Classes as to allocation of expenses, right
of redemption, special and relative rights as to dividends, and on liquidation,
conversion rights, and conditions under which the several Classes shall have
separate voting rights.  All references to Shares in this Declaration shall be
deemed to be Shares of any or all Classes as the context may require.

     If the Trustees shall divide the Shares of the Trust or any Series into two
or more Classes, the following provisions shall be applicable:

          (a)  All provisions herein relating to the Trust, or any Series of the
               Trust, shall apply equally to each Class of Shares of the Trust
               or of any Series of the Trust, except as the context requires
               otherwise.

          (b)  The number of Shares of each Class that may be issued shall be
               unlimited.  The Trustees may classify or reclassify any unissued
               Shares of the Trust or any Series or any Shares previously issued
               and reacquired of any Class of the Trust or of any Series into
               one or more Classes that may be established and designated from
               time to time.  The Trustees may hold as treasury Shares (of the
               same or some other Class), reissue for such consideration and on
               such terms as they may determine, or cancel any Shares of any
               Class reacquired by the Trust at their discretion from time to
               time.

          (c)  Liabilities, expenses, costs, charges and reserves related to the
               distribution of, and other identified expenses that should
               properly be allocated to, the Shares of a particular Class may be
               charged to and borne solely by such Class, and the bearing of
               expenses solely by a Class of Shares may be appropriately
               reflected (in a manner determined by the Trustees) and cause
               differences in the net asset value attributable to, and the
               dividend, redemption and liquidation rights of, the

                                       22
<PAGE>
 
               Shares of different Classes.  Each allocation of liabilities,
               expenses, costs, charges and reserves by the Trustees shall be
               conclusive and binding upon the Shareholders of all classes for
               all purposes.

     The establishment and designation of any Class of Shares shall be effective
upon the execution of a majority of the then Trustees of an instrument setting
forth such establishment and designation and the relative rights and preferences
of such Class, or as otherwise provided in such instrument.  The Trustees may,
by an instrument executed by a majority of their number, abolish any Class and
the establishment and designation thereof.  Each instrument referred to in this
paragraph shall have the status of an amendment to this Declaration.

     Section 6.3  Rights of Shareholders.  The ownership of the Trust Property
of every description and the right to conduct any business hereinbefore
described are vested exclusively in the Trustees, and the Shareholders shall
have no interest therein other than the beneficial interest conferred by their
Shares with respect to a particular Series or Class, and they shall have no
right to call for any partition or division of any property, profits, rights or
interests of the Trust nor can they be called upon to share or assume any losses
of the Trust, or suffer an assessment of any kind by virtue of their ownership
of Shares.  The Shares shall be personal property giving only the rights in this
Declaration specifically set forth.  The Shares shall not entitle the holder to
preference, preemptive, appraisal, conversion or exchange rights (except for
rights to exchange Shares of one Series for Shares of another Series or Class or
rights to convert shares of one Class for shares of another Class as set forth
in the Prospectus).

     Section 6.4  Trust Only.  It is the intention of the Trustees to create
only the relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time.  It is not the intention of the Trustees to
create a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than a trust.
Nothing in this Declaration shall be construed to make the Shareholders, either
by themselves or with the Trustees, partners or members of a joint stock
association.

     Section 6.5  Issuance of Shares.  The Trustees, in their discretion, may
from time to time without a vote of the Shareholders issue Shares with respect
to any Series that may have been established pursuant to Section 6.2.1 or any
Class that may have been established pursuant to Section 6.2.1, in addition to
the then issued and outstanding Shares and Shares held in the treasury, to such
party or parties and for such amount not less than the then current net asset
value of said Shares and type of consideration, including cash or property, at
such time or times and on such terms as the Trustee may deem best, and may in
such

                                       23
<PAGE>
 
manner acquire other assets (including the acquisition of assets subject to, and
in connection with the assumption of, liabilities) and businesses.  In
connection with any issuance of Shares, the Trustees may issue fractional
Shares.  The Trustees may from time to time divide or combine the Shares of any
Series or Class into a greater or lesser number without thereby changing the
proportionate beneficial interests in such Series or Class of the Trust.
Contributions to the Trust may be accepted for, and Shares shall be redeemed as,
whole Shares and/or 1/1,000ths of a Share or multiples thereof.

     Section 6.6  Register of Shares.  A register shall be kept at the Trust or
the offices of any transfer agent duly appointed by the Trustees under the
direction of the Trustees which shall contain the names and addresses of the
Shareholders and the number of Shares (with respect to each Series and Class
that may have been established) held by them respectively and a record of all
transfers thereof.  Separate registers shall be established and maintained for
each Series and Class of the Trust.  Each such register shall be conclusive as
to who are the holders of the Shares of the applicable Series and Class and who
shall be entitled to receive dividends or distributions or otherwise to exercise
or enjoy the rights of Shareholders.  No Shareholder shall be entitled to
receive payment of any dividend or distribution, nor to have notice given to him
as herein provided, until he has given his address to a transfer agent or such
other officer or agent of the Trustees as shall keep the register for entry
thereon.  The Trust shall not be required to issue certificates for the Shares;
however, the Trustees, in their discretion, may authorize the issuance of share
certificates and promulgate appropriate rules and regulations as to their use.

     Section 6.7  Transfer Agent and Registrar.  The Trustees, or an agent of
the Trust selected by the Trustees, shall have power to employ a transfer agent
or transfer agents, and a registrar or registrars, with respect to the Shares of
the various Series and Classes.  The transfer agent may keep the applicable
register and record therein the original issues and transfers, if any, of the
said Shares of the applicable Series and Classes.  Any such transfer agent and
registrar shall perform the duties usually performed by transfer agents and
registrars of certificates of stock in a corporation, except as modified by the
Trustees.

     Section 6.8  Transfer of Shares.  Except as otherwise provided by the
Trustees, Shares shall be transferable on the records of the Trust only by the

Item 27.  Indemnification.

          Reference is made to Article 5, Section 5.4 of the Registrant's
Agreement and Declaration of Trust, which is incorporated by reference herein.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant by the Registrant pursuant to the Fund's Articles of
Incorporation, its By-Laws or otherwise, the Registrant is aware that in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Act and, therefore, is unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by directors,
officers or controlling persons or the Registrant in connection with the
successful defense of any act, suit or proceeding) is asserted by such
directors, officers or controlling persons in connection with shares being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issues.

Item 28.  Business and Other Connections of Current Investment Adviser.

          Unless otherwise stated, the principal business address of each
organization listed is 840 Newport Center Drive, Newport Beach, CA  92660.

hereinafter provided;

     NOW, THEREFORE, the Trustees hereby declare that they will hold in trust
all money and property contributed to the trust fund to manage and dispose of
the same for the benefit of the holders from time to time of the shares of
beneficial interest issued hereunder and subject to the provisions hereof, to
wit:

                                   ARTICLE I

                                   The Trust

     Section 1.1  Name.  The name of the trust created hereby (the "Trust"),
which term shall be deemed to include any series of the Trust when the context
requires, shall be "PIMCO Advisors Institutional Funds", and so far as may be
practicable the Trustees shall conduct the activities of the Trust, execute all
documents and sue or be sued under that name, which name (and the word "Trust"
wherever hereinafter used) shall refer to the Trustees as Trustees, and not
individually, and shall not refer to the officers, agents, employees or
shareholders of the Trust or any Series thereof.  Each Series of the Trust which
shall be established and designated by the Trustees pursuant to Section 6.2
shall conduct its activities under such name as the Trustees

                                       5

shall determine and set forth in the instrument establishing such Series.
Should the Trustees determine that the use of the name of the Trust or any
Series is not advisable, they may select such other name for the Trust or such
Series as they deem proper and the Trust or such Series may conduct its
activities under such other name.  Any name change shall be effective upon the
execution by a majority of the then Trustees of an instrument setting forth the
new name.  Any such instrument shall have the status of an amendment to this
Agreement and Declaration of Trust.

Trust, the following terms shall have the following meanings:

to refer to the Declaration rather than the article or section in which such
words appear.

          "Fundamental Policies" shall mean the investment objective for each
Series and the investment restrictions set forth in the registration statement
for the Trust on Form N-1A and designated as fundamental policies therein.

they shall continue in office in accordance with the terms hereof, and all other
persons who at the time in question have been duly elected or appointed and have
qualified as Trustees in accordance with the provisions hereof and are then in
office, and each such person is herein referred to as the "Trustee", and
reference in this Declaration to a Trustee or Trustees shall refer to such
person or persons in their capacity as Trustees hereunder.

          "Trust Property" shall mean as of any particular time any and all
property, real or personal, tangible or intangible, which at such time is owned
or held by or for the account of the Trust, any Series thereof or the Trustees.

                                    Trustees

     Section 2.1  Management of the Trust.  The business and affairs of the
Trust shall be managed by the Trustees, and they shall have all powers necessary
and desirable to carry out that responsibility.  The Trustees named herein (or
their successors appointed hereunder) shall serve until the election of Trustees
at the first meeting of Shareholders of the Trust.

     Section 2.2  Election of Trustees.  Except for the Trustees named herein
and those Trustees designated by such Trustees prior to the issuance of Shares,
or appointed to fill vacancies pursuant to Section 2.4 hereof, the Shareholders
of the Trust shall elect Trustees at Shareholder meetings called for that
purpose.  The Trustees need not be elected annually or at regular intervals.
Except as provided in Section 9.2, the Trustees shall not be required to call a
meeting of Shareholders for the purpose of electing Trustees, provided, however,
that in the event that at any time, other than the time preceding the first
meeting of Shareholders for the purpose of electing Trustees, less than a
majority of the Trustees holding office at that time were elected by the
Shareholders, a meeting of the Shareholders for the

                                       7
<PAGE>
 
purpose of electing Trustees shall be held promptly and in any event within 60
days (unless the Commission shall by order extend such period).  No election of
a Trustee shall become effective, however, until the person elected shall have
accepted such election and agreed in writing to be bound by the terms of this
Declaration.  If re-elected, a Trustee may succeed himself.  Trustees need not
own shares.

     Section 2.3  Term of Office of Trustees.  A Trustee duly appointed or
elected hereunder shall hold office until the occurrence of any of the
following:  (a) the Trustee may resign his trust by written instrument signed by
him and delivered to the other Trustees, which shall take effect upon such
delivery or upon such later date as is specified therein; (b) the Trustee may be
removed at any time by written instrument signed by at least two-thirds of the
number of Trustees prior to such removal, specifying the date when such removal
shall become effective; (c) the Trustee who requests in writing to be retired or
who has become mentally or physically incapacitated may be retired by written
instrument signed by a majority of the other Trustees, specifying the date of
his retirement; and (d) the Trustee may be removed at any meeting of
Shareholders of the Trust by a vote of two-thirds of the outstanding Shares or
by a written declaration executed, without a meeting, by the holders of not less
than two-thirds of the outstanding Shares.  A meeting for the purpose of
considering the removal of a person serving as Trustee shall be called by the
Trustees if requested in writing to do so by the holders (which for purposes of
this provision and only this provision shall be the persons having a voting
interest in the shares of the Trust) of not less than 10% of the outstanding
shares of the Trust.

     Section 2.4  Termination of Service and Appointment of Trustees.  In case
of the death, resignation, retirement, removal or mental or physical incapacity
of any of the Trustees, or in case a vacancy shall, by reason of an increase in
number, or for any other reason, exist, the remaining Trustees may (but need not
unless required by the 1940 Act, so long as there are at least two remaining
Trustees) fill such vacancy by appointing for the remaining term of the
predecessor Trustee such other person as they in their discretion shall see fit.
Such appointment shall be effective upon the signing of a written instrument by
a majority of the Trustees in office and the written acceptance of this
Declaration by the appointee.  An appointment of a Trustee may be made by the
Trustees then in office in anticipation of a vacancy to occur by reason of
retirement, resignation or increase in number of Trustees effective at a later
date, provided that said appointment shall become effective only at or after the
effective date of said retirement, resignation or increase in number of Trustees
and the written acceptance of this Declaration by the appointee.  As soon as any
Trustee so appointed shall have accepted this Trust, the trust estate shall vest
in the new Trustee or Trustees, together with the continuing Trustees, without
any further act or conveyance, and he shall be deemed a

                                       8
<PAGE>
 
Trustee hereunder.  Any appointment authorized by this Section 2.4 is subject to
the provisions of Section 16(a) of the 1940 Act.

     Section 2.5  Temporary Absence of Trustee.  Any Trustee may, by power of
attorney, delegate his power for a period not exceeding six months at any one
time to any other Trustee or Trustees, provided that in no case shall less than
two of the Trustees personally exercise the power hereunder except as herein
otherwise expressly provided.

     Section 2.6  Number of Trustees.  The number of Trustees serving hereunder
at any time shall be determined by the Trustees themselves, but once Shares have
been issued shall not be less than two (2) or more than fifteen (15).

     Section 2.7  Effect of Death, Resignation, etc. of a Trustee.  The death,
resignation, retirement, removal, or mental or physical incapacity of the
Trustees, or any one of them, shall not operate to annul or terminate the Trust
or any Series hereunder or to revoke or terminate any existing agency or
contract created pursuant to the terms of this Declaration, and until such
vacancy is filled, the Trustees in office, regardless of their number, shall
have all of the powers granted to the Trustees and shall discharge all the
duties imposed upon them by this Declaration.

     Section 2.8  No Accounting.  Except to the extent required by the 1940 Act
or under circumstances which would justify his removal for cause, no person
ceasing to be a Trustee as a result of his death, resignation, retirement,
removal or incapacity (nor the estate of any such person) shall be required to
make an accounting to the shareholders or remaining Trustees upon such
cessation.

     Section 2.9  Ownership of the Trust.  The assets of the Trust shall be held
separate and apart from any assets now or hereafter held in any capacity other
than as Trustee hereunder by the Trustees or by any successor Trustees.  All of
the assets of the Trust shall at all times be considered as vested in the
Trustees.  No Shareholder shall be deemed to have a severable ownership in any
individual asset of the Trust or any right of partition or possession thereof,
but each Shareholder shall have a proportionate undivided beneficial interest in
the Trust.

                                  ARTICLE III

                               Powers of Trustees

     Section 3.1  General.  The Trustees in all instances shall act as
principals, and are and shall be free from the control of the Shareholders.  The
Trustees shall have full power and authority to do any and all acts and to make

necessary or

                                       9
<PAGE>
 
appropriate in connection with the management of the Trust.  The Trustees shall
not be bound or limited by present or future laws or customs with regard to
investment by trustees or fiduciaries, but shall have full authority and
absolute power and control over the Trust Property and business of the Trust to
the same extent as if the Trustees were the sole owners of the Trust Property
and business in their own right, including such authority, power and control to
do all acts and things as they, in their uncontrolled discretion, shall deem
proper to accomplish the purposes of this Trust.  The enumeration of any
specific power herein shall not be construed as limiting the aforesaid powers.

     Section 3.2  Investments.  The Trustees shall have power, subject to the
Fundamental Policies, to:

          (a)  conduct, operate and carry on the business of an investment
               company;

               instruments, bank obligations, evidences of indebtedness,
               privately placed debt securities, certificates of deposit or
               indebtedness, commercial paper, repurchase agreements, reverse
               repurchase agreements, firm commitment agreements and "when-
               issued" securities and other securities, including, without
               limitation, those issued, guaranteed, or sponsored by any state,
               territory or possession of the United States and the District of
               Columbia and their political subdivisions, agencies and
               instrumentalities, or by the United States Government or its
               agencies or instrumentalities, or international
               instrumentalities, or by any bank, savings institution,
               corporation or other business entity organized under the laws of
               the United States and, to the extent provided in the Prospectus
               and not prohibited by the Fundamental Policies of the Trust,
               foreign securities of issuers or governments organized under
               foreign laws, foreign currency transactions and options on
               foreign currency transactions, and

                                       10

               other assets; and to exercise any and all rights, powers and
               privileges of ownership or interest in respect of any and all
               such investments of every kind and description, with power to
               designate one or more persons, firms, associations or
               corporations to exercise any of said rights, powers and
               privileges in respect of any of said instruments; and the
               Trustees shall be deemed to have the foregoing powers with
               respect to any additional securities or other assets in which any
               Series of the Trust may invest should the investment policies set
               forth in the Prospectus or the Fundamental Policies be amended.

     The Trustees shall not be limited to investing in obligations maturing
before the possible termination of the Trust or any Series.

     Section 3.3  Legal Title.  Legal title to all the Trust Property shall be
vested in the Trustees as joint tenants except that the Trustees shall have
power to cause legal title to any Trust Property to be held by or in the name of
one or more of the Trustees, or in the name of the Trust or any Series thereof,
or in the name of any other Person as nominee, on such terms as the Trustees may
determine, provided that the interest of the Trust or any Series thereof is
appropriately protected.

     Section 3.4  Issuance and Repurchase of Securities.  The Trustees shall
have the power to issue, sell, repurchase, redeem, retire, cancel, acquire,
hold, resell, reissue, dispose of, transfer, and otherwise deal in, Shares,
including shares in fractional denominations, and, subject to the more detailed
provisions set forth in Articles VII and VIII, to apply to any such repurchase,
redemption, retirement, cancellation or acquisition of Shares any funds or
property of the applicable Series of the Trust whether capital or surplus or
otherwise, to the full extent now or hereafter permitted by the laws of the
Commonwealth of Massachusetts governing business corporations.

     Section 3.5  Borrow Money.  Subject to the Fundamental Policies, the
Trustees shall have power to borrow money or otherwise obtain credit and to
secure the same by mortgaging, pledging or otherwise subjecting as security the

securities, and to endorse, guarantee or undertake the performance of any
obligation, contract or engagement of any other person, form, association or
corporation.

     Section 3.6  Officers; Delegation; Committees.  The Trustees may, as they
consider appropriate, elect and remove officers and appoint and terminate agents
and consultants and hire and terminate employees, any one or more of the
foregoing of whom may be a Trustee and may provide for the compensation of all

                                       11
<PAGE>
 
continuing exclusive authority over the management of the Trust and the Trust
Property, to delegate from time to time to such of their number or to officers,
employees or agents of the Trust the doing of such things and the execution of
such instruments either in the name of the Trust or the names of the Trustees or
otherwise as the Trustees may deem expedient.  The Trustees may appoint from
their number and terminate any one or more committees consisting of two or more
Trustees, including without implied limitation an Executive Committee which may,
when the Trustees are not in session and subject to the 1940 Act, exercise some
or all of the powers and authority of the Trustees as the Trustees may
determine.

the Trustees may be taken by a majority of the Trustees present at a meeting of

business of the Trust.

                                       12
<PAGE>

pay, and to pay, such portion of the expenses and compensation of such
committee, depositary or trustee as the Trustees shall deem proper.

(a) employ or contract with such Persons as the Trustees may deem desirable for
the transaction of the business of the Trust or any Series or Class thereof; (b)

agents, investment advisers, distributors, selected dealers or independent
contractors of the Trust or any Series or Class thereof against all claims
arising by reason of holding any such position or by reason of any action taken
or omitted by any such Person in such capacity, whether or not constituting
negligence, or whether or not the Trust would have the power to indemnify such
Person against such liability; (d) establish pension, profit-sharing, share
purchase, and other retirement, incentive and benefit plans for any Trustees,
officers, employees and agents of the Trust; (e) make donations, irrespective of

of foreign governments, and to do all such other things and execute all such
instruments as they deem necessary, proper or desirable in order to promote the
interests of the Trust or any Series or Class thereof although such things are
not herein specifically mentioned.  Any determination as to what is in the
interests of the Trust or any Series or Class thereof made by the Trustees in
good faith shall be conclusive.  In construing the provisions of this
Declaration, the presumption shall be in favor of a grant of power to the
Trustees.  The Trustees will not be required to obtain any court

                                       13
<PAGE>
 
order to deal with the Trust Property.  No Trustee shall be required to give any
bond or other security for the performance of any of his duties hereunder.

                                   ARTICLE IV

                      Advisory, Administrative, Management
                         and Distribution Arrangements

     Section 4.1  Advisory and Management Arrangements.  Subject to a Majority
Shareholder Vote, if required by law, of the applicable Series, the Trustees may
in their discretion from time to time enter into advisory, administrative or
management contracts whereby the other party to such contract shall undertake to
furnish to the Trustees such advisory, administrative and management services,
with respect to a Series as the Trustees shall from time to time consider
desirable and all upon such terms and conditions as the Trustees may in their
discretion determine.  Subject to a Majority Shareholder Vote if required by
law, the investment adviser may engage one or more firms to serve as Portfolio
Manager to a Series pursuant to a sub-investment advisory contract in which the
Portfolio Manager makes all determinations with respect to the purchase and sale
of portfolio securities and places, in the names of the Series all orders for
execution of the Series' portfolio transactions upon such terms and conditions
and for such compensation as the Trustees may in their discretion approve.  A
Portfolio Manager may, in turn, engage its own sub-adviser in managing a
particular Series.  Notwithstanding any provisions of this Declaration, the
Trustees may authorize any adviser, portfolio manager, administrator or manager
(subject to such general or specific instructions as the Trustees may from time
to time adopt) to effect purchases, sales, loans or exchanges of portfolio
securities of any Series of the Trust on behalf of the Trustees or may authorize
any officer, employee or Trustee to effect such purchases, sales, loans or
exchanges pursuant to recommendations of any such adviser, portfolio manager,
administrator or manager (and all without further action by the Trustees).  Any
such purchases, sales, loans or exchanges shall be deemed to have been
authorized by all of the Trustees.

     Section 4.2  Distribution Arrangements.  The Trustees may in their
discretion from time to time enter into a contract, providing for the sale of
the Shares of the Trust or any Series or Class of the Trust, whereby the Trust
may either agree to sell the Shares to the other party to the contract or
appoint such other party as its sales agent for such Shares.  In either case,
the contract shall be on such terms and conditions as the Trustees may in their
discretion determine to be not inconsistent with the provisions of this Article
IV or the By-laws; and such contract may also provide for the repurchase or sale
of Shares by such other party as principal or as agent of the Trust and may
provide that such other party may enter into selected dealer agreements with
registered securities dealers to further the

                                       14
<PAGE>
 
purpose of the distribution or repurchase of the Shares.  The Trustees may adopt
a Distribution Plan pursuant to Rule 12b-1 of the 1940 Act and may authorize the
Trust to make payments from its assets pursuant to such Plan.

     Section 4.3  Parties to Contract.  Any contract of the character described
in Sections 4.1 and 4.2 of this Article IV hereof may be entered into with any
corporation, firm, trust or association, although one or more of the Trustees or
officers of the Trust may be an officer, director, Trustee, shareholder or
member of such other party to the contract, and no such contract shall be
invalidated or rendered voidable by reason of the existence of any such
relationship, nor shall any person holding such relationship be liable merely by
reason of such relationship for any loss or expense to the Trust under or by
reason of said contract or accountable for any profit realized directly or
indirectly therefrom, provided that the contract when entered into was
reasonable and fair and not inconsistent with the provisions of this Article IV
or the By-laws.  The same person (including a firm, corporation, trust or
association) may be the other party to contracts entered into pursuant to
Sections 4.1 and 4.2 above, and any individual may be financially interested or
otherwise affiliated with persons who are parties to any or all of the contracts
mentioned in this Section 4.3.

     Section 4.4  Provisions and Amendments.  Any contract under which the other
party agrees to serve as investment adviser or principal underwriter for the
Fund or any Series or Class thereof, which is entered into pursuant to Sections
4.1 and 4.2 of this Article IV shall be consistent with and subject to the
requirements of Section 15 of the 1940 Act with respect to its continuance in
effect, its termination, and the method of authorization and approval of such
contract or renewal thereof, and no amendment to any contract entered into
pursuant to Section 4.1 shall be effective unless consented to by a Majority
Shareholder Vote of the applicable Series if required by law.

                                   ARTICLE V

         Limitations of Liability of Shareholders, Trustees and Others

     Section 5.1  Trustees, Shareholders, etc. Not Personally Liable; Notice.
All persons extending credit to, contracting with or having any claim against
the Trust shall look only to the assets of the Series with which such person
dealt for payment under such credit, contract or claim; and neither the
Shareholders of any Series nor the Trustees, nor any of the Trust's officers,
employees or agents, whether past, present or future, nor any other Series shall
be personally liable therefor.  Every note, bond, contract, instrument,
certificate or undertaking and every other act or thing whatsoever executed or
done by or on behalf of the Trust, any Series or Class, or the Trustees or any
of them in connection with the Trust shall be conclusively deemed to have been
executed or done only by or for the Trust (or the

                                       15
<PAGE>
 
Series or Class) or the Trustees and not personally.  Nothing in this
Declaration shall protect any Trustee or officer against any liability to the
Trust or the Shareholders to which such Trustee or officer would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of the office of
Trustee or of such officer.

     Every note, bond, contract, instrument, certificate, share or undertaking
made or issued by the Trustees or by any officers or officer shall give notice
that this Declaration is on file with the Secretary of The Commonwealth of
Massachusetts and shall recite to the effect that the same was executed or made
by or on behalf of the Trust or by them as Trustees or Trustee or as officers or
officer and not individually, and that the obligations of such bond, contract,
instrument, certificate, share or undertaking are not binding upon any of them
or the Shareholders individually but are binding only upon the assets and
property of the Trust, or the particular Series in question, as the case may be,
but the omission thereof shall not operate to bind any Trustees or Trustee or
officers or officer or Shareholders or Shareholder individually.

     Section 5.2  Trustee's Good Faith Action; Expert Advice; No Bond or Surety.
The exercise by the Trustees of their powers and discretion hereunder shall be
binding upon everyone interested.  A Trustee shall be liable for his own willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of the office of Trustee, and for nothing else, and
shall not be liable for errors of judgment or mistakes of fact or law.  Subject
to the foregoing, (a) the Trustees shall not be responsible or liable in any
event for any neglect or wrongdoing of any officer, agent, employee, consultant,
adviser, administrator, distributor or principal underwriter, custodian or
transfer, dividend disbursing, Shareholder servicing or accounting agent of the
Trust, nor shall any Trustee be responsible for the act or omission of any other
Trustee; (b) the Trustees may take advice of counsel or other experts with
respect to the meaning and operation of this Declaration and their duties as
Trustees, and shall be under no liability for any act or omission in accordance
with such advice or for failing to follow such advice; and (c) in discharging
their duties, the Trustees, when acting in good faith, shall be entitled to rely
upon the books of account of the Trust and upon written reports made to the
Trustees by any officer appointed by them, any independent public accountant,
and (with respect to the subject matter of the contract involved) any officer,
partner or responsible employee of any adviser, administrator, manager,
distributor, selected dealer, appraiser or other expert, consultant or agent.
The Trustees as such shall not be required to give any bond or surety or any
other security for the performance of their duties.

     Section 5.3  Indemnification of Shareholders.  In case any Shareholder (or
former Shareholder) of any Series of the Trust

                                       16
<PAGE>
 
shall be charged or held to be personally liable for any obligation or liability
of the Trust solely by reason of being or having been a Shareholder and not
because of such Shareholder's acts or omissions or for some other reason, said
Series (upon proper and timely request by the Shareholder) shall assume the
defense against such charge and satisfy any judgment thereon, and the
Shareholder or former Shareholder (or his heirs, executors, administrators or
other legal representatives or in the case of a corporation or other entity, its
corporate or other general successor) shall be entitled out of the assets of
said Series' estate to be held harmless from and indemnified against all loss
and expense arising from such liability.

     Section 5.4  Indemnification of Trustees, Officers, etc.  The Trust shall
indemnify (from the assets of the Trust or Series in question) each of its
Trustees and officers (including persons who serve at the Trust's request as
directors, officers or trustees of another organization in which the Trust has
any interest as a shareholder, creditor or otherwise) [hereinafter referred to
as a "Covered Person"] against all liabilities, including but not limited to
amounts paid in satisfaction of judgments, in compromise or as fines and
penalties, and expenses, including reasonable accountants' and counsel fees,
incurred by any Covered Person in connection with the defense or disposition of
any action, suit or other proceeding, whether civil or criminal, before any
court or administrative or legislative body, in which such Covered Person may be
or may have been involved as a party or otherwise or with which such person may
be or may have been threatened, while in office or thereafter, by reason of
being or having been such a Trustee or officer, director or trustee, except with
respect to any matter as to which it has been determined that such Covered
Person (i) did not act in good faith in the reasonable belief that such Covered
Person's action was in or not opposed to the best interests of the Trust or (ii)
had acted with willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such Covered Person's office
(either and both of the conduct described in (i) and (ii) being referred to
hereafter as "Disabling Conduct").  A determination that the Covered Person is
entitled to indemnification may be made by (i) a final decision on the merits by
a court or other body before whom the proceeding was brought that the person to
be indemnified was not liable by reason of Disabling Conduct, (ii) dismissal of
a court action or an administrative proceeding against a Covered Person for
insufficiency of evidence of Disabling Conduct, or (iii) a reasonable
determination, based upon a review of the facts, that the indemnitee was not
liable by reason of Disabling Conduct by (a) a vote of a majority of a quorum of
Trustees who are neither "interested persons" of the Trust as defined in section
2(a)(19) of the 1940 Act nor parties to the proceeding, or (b) an independent
legal counsel in a written opinion.  Expenses, including accountants' and
counsel fees so incurred by any such Covered Person (but excluding amounts paid
in satisfaction of judgments, in compromise or as fines or penalties), may be
paid from time to time by

                                       17
<PAGE>
 
the Series in question in advance of the final disposition of any such action,
suit or proceeding, provided that the Covered Person shall have undertaken to
repay the amounts so paid to the Series in question if it is ultimately
determined that indemnification of such expenses is not authorized under this
Article V and (i) the Covered Person shall have provided security for such
undertaking, (ii) the Trust shall be insured against losses arising by reason of
any lawful advances, or (iii) a majority of a quorum of the disinterested
Trustees who are not a party to the proceeding, or an independent legal counsel
in a written opinion, shall have determined, based on a review of readily
available facts (as opposed to a full trial-type inquiry), that there is reason
to believe that the Covered Person ultimately will be found entitled to
indemnification.

     Section 5.5  Compromise Payment.  As to any matter disposed of by a
compromise payment by any such Covered Person referred to in Section 5.4,
pursuant to a consent decree or otherwise, no such indemnification either for
said payment or for any other expenses shall be provided unless such
indemnification shall be approved (a) by a majority of the disinterested
Trustees who are not parties to the proceeding or (b) by an independent legal
counsel in a written opinion.  Approval by the Trustees pursuant to clause (a)
or by independent legal counsel pursuant to clause (b) shall not prevent the
recovery from any Covered Person of any amount paid to such Covered Person in
accordance with any of such clauses as indemnification if such Covered Person is
subsequently adjudicated by a court of competent jurisdiction not to have acted
in good faith in the reasonable belief that such Covered Person's action was in
or not opposed to the best interests of the Trust or to have been liable to the
Trust or its Shareholders by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office.

     Section 5.6  Indemnification Not Exclusive, etc.  The right of
indemnification provided by this Article V shall not be exclusive of or affect
any other rights to which any such Covered Person may be entitled.  As used in
this Article V, "Covered Person" shall include such person's heirs, executors
and administrators; "interested Covered Person" is one against whom the action,
suit or other proceeding in question or another action, suit or other proceeding
on the same or similar grounds is then or has been pending or threatened, and a
"disinterested" person is a person against whom none of such actions, suits or
other proceedings or another action, suit or other proceeding on the same or
similar grounds is then or has been pending or threatened.  Nothing contained in
this Article shall affect any rights to indemnification to which personnel of
the Trust, other than Trustees and officers, and other persons may be entitled
by contract or otherwise under law, nor the power of the Trust to purchase and
maintain liability insurance on behalf of any such person.

     Section 5.7  Liability of Third Persons Dealing with Trustees.  No person
dealing with the Trustees shall be bound to make any inquiry concerning the
validity of any transaction made or to be made by the Trustees or to see to the
application of any payments made or property transferred to the Trust or upon
its order.

                                   ARTICLE VI

                         Shares of Beneficial Interest

     Section 6.1  Beneficial Interest.  The interest of the beneficiaries
hereunder shall be divided into transferable shares of beneficial interest which
may be divided into one or more separate and distinct series, or classes
thereof, as the Trustees from time to time create and establish.  Each share
shall have a par value of $.001.  The number of such shares of beneficial
interest authorized hereunder is unlimited.  All Shares issued hereunder
including, without limitation, Shares issued in connection with a dividend in
Shares or a split of Shares, shall be fully paid and nonassessable.

     Section 6.2  Series Designation.  The Trustees, in their discretion from
time to time, may authorize the division of Shares into additional Series, each
additional Series relating to a separate portfolio of investments.  The
following Series are hereby established and designated:

          Utility Stock Fund
          NFJ Equity Income Fund
          NFJ Diversified Low P/E Fund
          NFJ Small Cap Value Fund

          International Active Variable Fund

These Series shall be the only Series until additional Series are established
and designated by the Trustees.  Different Series may be established and
designated and variations in the relative rights and preferences as between the
different Series shall be fixed and determined by the Trustees; provided that
all Shares shall be identical except that there may be variations between
different Series as to investment policies, securities portfolios, purchase
price, determination of net asset value, the price, terms and manner of
redemption, special and relative rights as to dividends and on liquidation,
conversion rights, and conditions under which the several Series shall have
separate voting rights.  All references to Shares in this Declaration shall be
deemed to be shares of any or all Series as the context may require.

     The following provisions shall be applicable to all Series:

          (a)  The number of Shares of each Series that may be issued shall be
               unlimited.  The Trustees may classify or reclassify any unissued
               Shares or any Shares previously issued and required of any Series
               into one or more Series that may be established and designated
               from time to time.  The Trustees may hold as treasury Shares (of
               the same or some other Series), reissue for such consideration
               and on such terms as they may determine, or cancel any Shares of
               any Series reacquired by the Trust at their discretion from time
               to time.

          (b)  The power of the Trustees to invest and reinvest the Trust
               Property of each Series that has been or that may be established
               shall be governed by Section 3.2 of this Declaration.

          (c)  All consideration received by the Trust for the issue or sale of
               Shares of a particular Series, together with all assets in which
               such consideration is invested or reinvested, all income,
               earnings, profits, and proceeds thereof, including any proceeds
               derived from the sale, exchange or liquidation of such assets,
               and any funds or payments derived from any reinvestment of such
               proceeds in whatever form the same may be, shall irrevocably
               belong to that Series for all purposes, subject only to the
               rights of creditors, and shall be so recorded upon the books of
               account of the Trust.  In the event that there are any assets,
               income, earnings, profits and proceeds thereof, funds or payments
               which are not readily identifiable as belonging to any particular
               Series, the Trustees shall allocate them among any one or more of
               the Series established and designated from time to

                                       20
<PAGE>
 
               time in such manner and on such basis as they, in their sole
               discretion, deem fair and equitable.  Each such allocation by the
               Trustees shall be conclusive and binding upon the Shareholders of
               all Series for all purposes.

          (d)  The assets belonging to each particular Series shall be charged
               with the liabilities of the Trust in respect of that Series and
               all expenses, costs, charges and reserves attributable to that
               Series, and any general liabilities, expenses, costs, charges or
               reserves of the Trust which are not readily identifiable as
               belonging to any particular Series shall be allocated and charged
               by the Trustees to and among any one or more of the Series
               established and designated from time to time in such manner and
               on such basis as the Trustees in their sole discretion deem fair
               and equitable.  Each allocation of liabilities, expenses, costs,
               charges and reserves by the Trustees shall be conclusive and
               binding upon the holders of all Series for all purposes.  The
               Trustees shall have full discretion, to the extent not
               inconsistent with the 1940 Act, to determine which items shall be
               treated as income and which items as capital; and each such
               determination and allocation shall be conclusive and binding upon
               the Shareholders.

          (e)  The power of the Trustees to pay dividends and make distributions
               with respect to any one or more Series shall be governed by
               Section 9.2 of this Trust.  Dividends and distributions on Shares
               of a particular Series may be paid with such frequency as the
               Trustees may determine, which may be daily or otherwise, pursuant
               to a standing resolution or resolutions adopted only once or with
               such frequency as the Trustees may determine, to the holders of
               Shares of that Series, from such of the income and capital gains,
               accrued liabilities belonging to that Series.  All dividends and
               distributions on Shares of a particular Series shall be
               distributed pro rata to the holders of that Series in proportion
               to the number of Shares of that Series held by such holders at
               the date and time of record established for the payment of such
               dividends or distributions.

     The establishment and designation of any additional Series of Shares shall
be effective upon the execution by a majority of the then Trustees of any
instrument setting forth the establishment and designation of such Series.  Such
instrument shall also set forth any rights and preferences of such Series which
are in addition to the rights and preferences of Shares set forth in this
Declaration.  The Trustees may by an instrument executed by

                                       21
<PAGE>
 
a majority of their number abolish a Series and the establishment and
designation thereof.  Each instrument referred to in this paragraph shall have
the status of an amendment to this Declaration.

     Section 6.2.1  Class Designation.  The Trustees, in their discretion, may
authorize the division of the Shares of the Trust or the Shares of any Series,
into two or more Classes, and the different Classes shall be established and
designated, and the variations in the relative rights and preferences as between
the different Classes shall be fixed and determined, by the Trustees; provided,
that all Shares of the Trust or of any Series shall be identical to all other
Shares of the Trust or the same Series, as the case may be, except that there
may be variations between different Classes as to allocation of expenses, right
of redemption, special and relative rights as to dividends, and on liquidation,
conversion rights, and conditions under which the several Classes shall have
separate voting rights.  All references to Shares in this Declaration shall be
deemed to be Shares of any or all Classes as the context may require.

     If the Trustees shall divide the Shares of the Trust or any Series into two
or more Classes, the following provisions shall be applicable:

          (a)  All provisions herein relating to the Trust, or any Series of the
               Trust, shall apply equally to each Class of Shares of the Trust
               or of any Series of the Trust, except as the context requires
               otherwise.

          (b)  The number of Shares of each Class that may be issued shall be
               unlimited.  The Trustees may classify or reclassify any unissued
               Shares of the Trust or any Series or any Shares previously issued
               and reacquired of any Class of the Trust or of any Series into
               one or more Classes that may be established and designated from
               time to time.  The Trustees may hold as treasury Shares (of the
               same or some other Class), reissue for such consideration and on
               such terms as they may determine, or cancel any Shares of any
               Class reacquired by the Trust at their discretion from time to
               time.

          (c)  Liabilities, expenses, costs, charges and reserves related to the
               distribution of, and other identified expenses that should
               properly be allocated to, the Shares of a particular Class may be
               charged to and borne solely by such Class, and the bearing of
               expenses solely by a Class of Shares may be appropriately
               reflected (in a manner determined by the Trustees) and cause
               differences in the net asset value attributable to, and the
               dividend, redemption and liquidation rights of, the

                                       22
<PAGE>
 
               Shares of different Classes.  Each allocation of liabilities,
               expenses, costs, charges and reserves by the Trustees shall be
               conclusive and binding upon the Shareholders of all classes for
               all purposes.

     The establishment and designation of any Class of Shares shall be effective
upon the execution of a majority of the then Trustees of an instrument setting
forth such establishment and designation and the relative rights and preferences
of such Class, or as otherwise provided in such instrument.  The Trustees may,
by an instrument executed by a majority of their number, abolish any Class and
the establishment and designation thereof.  Each instrument referred to in this
paragraph shall have the status of an amendment to this Declaration.

     Section 6.3  Rights of Shareholders.  The ownership of the Trust Property
of every description and the right to conduct any business hereinbefore
described are vested exclusively in the Trustees, and the Shareholders shall
have no interest therein other than the beneficial interest conferred by their
Shares with respect to a particular Series or Class, and they shall have no
right to call for any partition or division of any property, profits, rights or
interests of the Trust nor can they be called upon to share or assume any losses
of the Trust, or suffer an assessment of any kind by virtue of their ownership
of Shares.  The Shares shall be personal property giving only the rights in this
Declaration specifically set forth.  The Shares shall not entitle the holder to
preference, preemptive, appraisal, conversion or exchange rights (except for
rights to exchange Shares of one Series for Shares of another Series or Class or
rights to convert shares of one Class for shares of another Class as set forth
in the Prospectus).

     Section 6.4  Trust Only.  It is the intention of the Trustees to create
only the relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time.  It is not the intention of the Trustees to
create a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than a trust.
Nothing in this Declaration shall be construed to make the Shareholders, either
by themselves or with the Trustees, partners or members of a joint stock
association.

     Section 6.5  Issuance of Shares.  The Trustees, in their discretion, may
from time to time without a vote of the Shareholders issue Shares with respect
to any Series that may have been established pursuant to Section 6.2.1 or any
Class that may have been established pursuant to Section 6.2.1, in addition to
the then issued and outstanding Shares and Shares held in the treasury, to such
party or parties and for such amount not less than the then current net asset
value of said Shares and type of consideration, including cash or property, at
such time or times and on such terms as the Trustee may deem best, and may in
such

                                       23
<PAGE>
 
manner acquire other assets (including the acquisition of assets subject to, and
in connection with the assumption of, liabilities) and businesses.  In
connection with any issuance of Shares, the Trustees may issue fractional
Shares.  The Trustees may from time to time divide or combine the Shares of any
Series or Class into a greater or lesser number without thereby changing the
proportionate beneficial interests in such Series or Class of the Trust.
Contributions to the Trust may be accepted for, and Shares shall be redeemed as,
whole Shares and/or 1/1,000ths of a Share or multiples thereof.

     Section 6.6  Register of Shares.  A register shall be kept at the Trust or
the offices of any transfer agent duly appointed by the Trustees under the
direction of the Trustees which shall contain the names and addresses of the
Shareholders and the number of Shares (with respect to each Series and Class
that may have been established) held by them respectively and a record of all
transfers thereof.  Separate registers shall be established and maintained for
each Series and Class of the Trust.  Each such register shall be conclusive as
to who are the holders of the Shares of the applicable Series and Class and who
shall be entitled to receive dividends or distributions or otherwise to exercise
or enjoy the rights of Shareholders.  No Shareholder shall be entitled to
receive payment of any dividend or distribution, nor to have notice given to him
as herein provided, until he has given his address to a transfer agent or such
other officer or agent of the Trustees as shall keep the register for entry
thereon.  The Trust shall not be required to issue certificates for the Shares;
however, the Trustees, in their discretion, may authorize the issuance of share
certificates and promulgate appropriate rules and regulations as to their use.

     Section 6.7  Transfer Agent and Registrar.  The Trustees, or an agent of
the Trust selected by the Trustees, shall have power to employ a transfer agent
or transfer agents, and a registrar or registrars, with respect to the Shares of
the various Series and Classes.  The transfer agent may keep the applicable
register and record therein the original issues and transfers, if any, of the
said Shares of the applicable Series and Classes.  Any such transfer agent and
registrar shall perform the duties usually performed by transfer agents and
registrars of certificates of stock in a corporation, except as modified by the
Trustees.

     Section 6.8  Transfer of Shares.  Except as otherwise provided by the
Trustees, Shares shall be transferable on the records of the Trust only by the
record holder thereof or by his agent thereto duly authorized in writing, upon
delivery to the Trustees or a transfer agent of the Trust of a duly executed
instrument of transfer, together with such evidence of the genuineness of each
such execution and authorization and of other matters as may reasonably be
required.  Upon such delivery, the transfer shall be recorded on the applicable
register of the Trust.  Until such record is made, the Shareholder of record
shall be deemed to be the holder of such Shares for all purposes

                                       24
<PAGE>
 
hereof and neither the Trustees nor any transfer agent or registrar nor any
officer, employee or agent of the Trust shall be affected by any notice of the
proposed transfer.

     Any person becoming entitled to any Shares in consequence of the death,
bankruptcy or incompetence of any Shareholder, or otherwise by operation of law,
shall be recorded on the applicable register of Shares as the holder of such
Shares upon production of the proper evidence thereof to the Trustees or a
transfer agent of the Trust, but until such record is made, the Shareholder of
record shall be deemed to be the holder of such Shares for all purposes hereof
and neither the Trustees nor any transfer agent or registrar nor any officer or
agent of the Trust shall be affected by any notice of such death, bankruptcy or
incompetence, or other operation of law.

     Section 6.9  Notice.  Any and all notices to which any Shareholder
hereunder may be entitled and any and all communications shall be deemed duly
served or given if mailed, postage prepaid, addressed to any Shareholder of
record at his last known address as recorded on the applicable register of the
Trust.

                                  ARTICLE VII

                                   Redemption


     Section 7.1  Redemptions.  All outstanding Shares of any Series and Class
of the Trust may be redeemed at the option of the holders thereof, upon and
subject to the terms and conditions provided in this Article VII.  The Trust
shall, upon application of any Shareholder or pursuant to authorization from any
Shareholder of a particular Series or Class, redeem or repurchase from such
Shareholder outstanding Shares of such Series or Class for the following amount:
with respect to the Shares of any Series, the then current net asset value of
such Shares.

     For purposes of paragraph (b):  (A) if a redemption request identifies
Shares to be redeemed by indicating the manner and date of their acquisition,
then the Trust shall redeem the Shares so identified; (B) if a redemption
request does not contain such identification of the Shares to be redeemed, then
to the extent of the number of Shares which are the subject thereof, such
redemption request shall be deemed to request the redemption of Shares held by
the Shareholder in the following order:  first, Shares purchased at least one
year before receipt of such redemption request; second, Shares acquired upon
reinvestment of dividends or distributions; and third, Shares purchased less
than one year before receipt of such redemption request; and (C) the Trustees
may implement such procedures, including procedures related to the transfer of
Shares, and take such actions as are necessary for the Trust to effect
redemptions in a manner consistent with this paragraph (b).

     Notwithstanding the provisions of Section 10.4 of this Declaration, the
Trustees may amend this Declaration to modify or delete the provisions contained
in paragraph (b) of this Section 7.1 by an instrument in writing signed by a
majority of the then Trustees (or by an officer of the Trust pursuant to the
vote of a majority of such Trustees) without obtaining shareholder approval.

     If so authorized by the Trustees, the Trust may, at any time and from time
to time, charge fees or deferred sales charges for effecting such redemption, at
such rates as the Trustees may establish, as and to the extent permitted under
the 1940 Act, and may, at any time and from time to time, pursuant to such Act,
suspend such right of redemption.  The procedures for effecting redemption shall
be as set forth in the Prospectus with respect to the applicable Series or Class
from time to time.

     The Trust may repurchase Shares directly, through the Distributor or
another agent designated for the purpose by agreement with the owner thereof at
a price not exceeding the net asset value per share as determined as of the time
when the contract purchase is made or the net asset value as of any time which
may be later determined pursuant to Section 8.1 hereof, provided payment is not
made for the Shares prior to the time as of which such net asset value is
determined.

     Section 7.2  Redemptions of Accounts of Less than a Minimum Dollar Amount.
The Trustees shall have the power to redeem shares at a redemption price
determined in accordance with Section 7.1 if at any time the total investment in
such account does not have a minimum dollar value determined from time to time
by the Trustees in their sole discretion; provided, however, that the Trustees
may exercise such power with respect to Shares of any Series or Class only to
the extent the Prospectus or Statement of Additional Information describes such
power with respect to such Series or Class.  In the event the Trustees determine
to exercise their power to redeem Shares provided in this Section 7.2,
Shareholders shall be notified that the value of their account is less than the
then effective minimum dollar amount and allowed at least 30 days to make an
additional investment before redemption is processed.

                                  ARTICLE VIII

         Determination of Net Asset Value, Net Income and Distributions

     Section 8.1  Net Asset Value.  The net asset value of each outstanding
Share of each Series and Class of the Trust shall be determined with respect to
each Series and Class at such time or times on such days as the Trustees may
determine, in accordance with the 1940 Act.  The method of determination of net
asset value shall be determined by the Trustees and shall be as set forth in the
Prospectus or Statement of Additional Information with respect to the applicable
Series or Class.  The power and

                                       26
<PAGE>
 
duty to make the daily calculations for any Series or Class may be delegated by
the Trustees, or an agent of the Trust selected by the Trustees, to the adviser,
administrator, manager, custodian, transfer agent or such other person as the
Trustees or an agent of the Trust selected by the Trustees may determine.  The
Trustees may suspend the daily determination of net asset value to the extent
permitted by the 1940 Act.

     Section 8.2  Distributions to Shareholders.  Except at such times when the
Trustees deem proper, the Trustees will not distribute to Shareholders net
investment income and realized capital gains, but will retain and reinvest such
net profits.  The Trustees may make distributions to Shareholders to the extent
the distribution and the circumstances in which it may be made are determined by
the Trustees to be in the best interests of the Series or Class.  The Trustees
may retain and not reinvest from the net profits such amount as they may deem
necessary to pay the debts or expenses of the Trust or to meet obligations of
the Trust, or as they may deem desirable to use in the conduct of its affairs or
to retain for future requirements or extensions of the business.

     Section 8.3  Power to Modify Foregoing Procedures.  Notwithstanding any of
the foregoing provisions of this Article VIII, the Trustees may prescribe, in
their absolute discretion, such other bases and times for determining the per
share net asset value of the Trust's Shares or net income, or the declaration
and payment of dividends and distributions as they may deem necessary or
desirable to enable the Trust to comply with any provision of the 1940 Act, or
any securities association registered under the Securities Exchange Act of 1934,
or any order of exemption issued by said Commission, all as in effect now or
hereafter amended or modified.

                                   ARTICLE IX

                                  Shareholders

     Section 9.1  Voting Powers.  The Shareholders shall have the power to vote
(i) for the election of Trustees as provided in Article II, Section 2.2; (ii)
for the removal of Trustees as provided in Article II, Section 2.3(d); (iii)
with respect to any investment adviser as provided in Article IV, Section 4.1;
(iv) with respect to the merger, consolidation and sale of assets of the Trust
as provided in Article X, Section 10.3; (v) with respect to the amendment of
this Declaration as provided in Article X, Section 10.4; (vi) to the same extent
as the Shareholders of a Massachusetts business corporation as to whether or not
a court action, proceeding or claim should be brought or maintained derivatively
or as a class action on behalf of the Trust or the Shareholders (provided,
however, that a shareholder of a particular Series or Class shall not be
entitled to a derivative or class action on behalf of any other Series or Class
(or shareholders of any other Series or Class) of the Trust); and

                                       27
<PAGE>
 
(vii) with respect to such additional matters relating to the Trust as may be
required by law, by this Declaration, or the By-laws of the Trust or any
regulation of the Trust, by the Commission or any State, or as the Trustees may
consider desirable.  Any matter affecting a particular Series or Class,
including without limitation, matters affecting the investment advisory
arrangements or investment policies or restrictions of a Series or Class, if
required by law, shall not be deemed to have been effectively acted upon unless
approved by the required vote of the Shareholders of such Series or Class if
required by law.  Unless otherwise required by law, each whole Share shall be
entitled to one vote as to any matter on which it is entitled to vote, and each
fractional Share shall be entitled to a proportionate fractional vote.  There
shall be no cumulative voting in the election of Trustees.  Until Shares are
issued, the Trustees may exercise all rights of Shareholders and may take any
action to be taken by Shareholders which is required or permitted by law, this
Declaration or any By-laws of the Trust.

     Section 9.2  Meetings.  Shareholder meetings shall be held as specified in
the By-laws and in Section 2.2 hereof at the principal office of the Trust or at
such other place as the Trustees may designate.  No annual or regular meetings
of shareholders are required.  Meetings of the Shareholders may be called by the
Trustees and shall be held at such times, on such day and at such hour as the
Trustees may from time to time determine, for the purposes specified in Section
2.2 and for such other purposes as may be specified by the Trustees.

     Section 9.3  Quorum and Required Vote.  Except as otherwise provided by
law, the holders of thirty percent of the outstanding Shares of each Series
present in person or by proxy shall constitute a quorum for the transaction of
any business at any meeting of Shareholders.  If a quorum, as above defined,
shall not be present for the purpose of any vote that may properly come before
the meeting, the Shareholders present in person or by proxy and entitled to vote
at such meeting on such matter holding a majority of the Shares present entitled
to vote on such matter may by vote adjourn the meeting from time to time to be
held at the same place without further notice than by announcement to be given
at the meeting until a quorum, as above defined, entitled to vote on such matter
shall be present, whereupon any such matter may be voted upon at the meeting as
though held when originally convened.  Subject to any applicable requirement of
law, this Declaration or the By-laws, a plurality of the votes cast shall elect
a Trustee and all other matters shall be decided by a majority of the votes cast
entitled to vote thereon.

     Section 9.4  Record Date for Meetings.  For the purpose of determining the
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purpose of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding 30 days, as the Trustees may determine; or without closing the

                                       28
<PAGE>
 
transfer books the Trustees may fix a date not more than 180 days prior to the
date of any meeting of Shareholders or declaration of dividends or other action
as a record date for the determination of the persons to be treated as
Shareholders of record for such purposes, except for dividend payments which
shall be governed by Section 8.2 hereof.

     Section 9.5  Proxies.  Any vote by a Shareholder of the Trust may be made
in person or by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Trustees or their designee
prior to the time the vote is taken.  Pursuant to a resolution of a majority of
the Trustees, proxies may be solicited in the name of one or more Trustees or
one or more officers of the Trust.  Only Shareholders of record shall be
entitled to vote.  A proxy purporting to be executed by or on behalf of a
Shareholder shall be deemed valid unless challenged at or prior to its exercise,
and the burden of proving invalidity shall rest on the challenger.  A proxy with
respect to shares held in the name of two or more persons shall be valid if
executed by any one of them unless at or prior to exercise of the proxy the
Trust receives a specific written notice to the contrary from any one of them.

     Section 9.6  Additional Provisions.  The By-laws may include further
provisions for Shareholders' votes, meetings and related matters.

     Section 9.7  Reports.  The Trustees shall cause to be prepared with respect
to each Series at least annually a report of operations containing a balance
sheet and statement of income and undistributed income of the applicable Series
of the Trust prepared in conformity with generally accepted accounting
principles and an opinion of an independent public accountant on such financial
statements.  It is contemplated that separate reports may be prepared for the
various Series or Classes.  Copies of such reports shall be mailed to all
Shareholders of record of the applicable Series within the time required by the
1940 Act.  The Trustees shall, in addition, furnish to the Shareholders at least
semi-annually, interim reports containing an unaudited balance sheet of the
Series as of the end of such period and an unaudited statement of income and
surplus for the period from the beginning of the current fiscal year to the end
of such period.

     Section 9.8  Shareholder Action by Written Consent.  Any action which may
be taken by Shareholders may be taken without a meeting if a majority of
Shareholders of each Series or Class entitled to vote on the matter (or such
larger proportion thereof as shall be required by any express provision of this
Declaration) consent to the action in writing and the written consents are filed
with the records of the meetings of Shareholders.  Such consent shall be treated
for all purposes as a vote taken at a meeting of Shareholders.

            Duration; Termination of Trust; Amendment; Mergers; Etc.

          Section 10.1  Duration.  Subject to the provisions of Sections 11.2
and 11.3 hereof, this Trust shall continue without limitation of time.

          Section 10.2  Termination.

          (a)  The Trust, or any Series thereof, may be terminated by the
               affirmative vote of a majority of the Trustees, or by the
               affirmative vote of a majority of the Shares of the Trust or
               Series outstanding and entitled to vote, at any meeting of
               shareholders.  Upon the termination of the Trust or any Series:

               (i)  the Trust or such Series shall carry on no business except
                    for the purpose of winding up its affairs;

               (ii) the Trustees shall proceed to wind up the affairs of the
                    Trust or such Series and all of the powers of the Trustees
                    under this Declaration shall continue until the affairs of
                    the Trust or such Series shall have been wound up, including
                    the power to fulfill or discharge the contracts of the Trust
                    or such Series, collect its assets, sell, convey, assign,
                    exchange, transfer or otherwise dispose of all or any part
                    of the remaining Trust Property to one or more persons at
                    public or private sale for consideration which may consist
                    in whole or in part of cash, securities or other property of
                    any kind, discharge or pay its liabilities, and do all other
                    acts appropriate to liquidate its business; provided that
                    any sale, conveyance, assignment, exchange, transfer or
                    other disposition of all or substantially all the Trust
                    Property shall require approval of the principal terms of
                    the transaction and the nature and amount of the
                    consideration by vote or consent of the holders of a
                    majority of the Shares entitled to vote; and

             (iii)  after payment or adequately providing for the payment of all
                    liabilities, and upon receipt of such releases, indemnities
                    and refunding agreements as they deem necessary for their
                    protection, the Trustees may distribute the remaining Trust
                    Property of any Series, in cash or in kind or partly each,
                    among the

                                       30
<PAGE>
 
                    Shareholders of such Series according to their respective
                    rights.

          (b)  After termination of the Trust or any Series and distribution to
               the Shareholders as herein provided, a majority of the Trustees
               shall execute and lodge among the records of the Trust an
               instrument in writing setting forth the fact of such termination.
               Upon termination of the Trust, the Trustees shall thereupon be
               discharged from all further liabilities and duties hereunder, and
               the rights and interests of all Shareholders shall thereupon
               cease.  Upon termination of any Series, the Trustees thereunder
               shall be discharged from any further liabilities and duties with
               respect to such Series, and the rights and interests of all
               Shareholders of such Series shall thereupon cease.

     Section 10.3  Reorganization.  The Trustees may sell, convey, merge and
transfer the assets of the Trust, or the assets belonging to any one or more
Series, to another trust, partnership, association or corporation organized
under the laws of any state of the United States, or to the Trust to be held as
assets belonging to another Series of the Trust, in exchange for cash, shares or
other securities (including, in the case of a transfer to another Series of the
Trust, Shares of such other Series) with such transfer either (1) being made
subject to, or with the assumption by the transferee of, the liabilities
belonging to each Series the assets of which are so transferred, or (2) not
being made subject to, or not with the assumption of, such liabilities;
provided, however, that no assets belonging to any particular Series shall be so
transferred unless the terms of such transfer shall have first been approved at
a meeting called for the purpose by a Majority Shareholder Vote of that Series.
Following such transfer, the Trustees shall distribute such cash, shares or
other securities (giving due effect to the assets and liabilities belonging to
and any other differences among the various Series the assets belonging to which
have so been transferred) among the Shareholders of the Series the assets
belonging to which have been so transferred; and if all of the assets of the
Trust have been so transferred, the Trust shall be terminated.

     The Trust, or any one or more Series, may, either as the successor,
survivor, or non-survivor, (1) consolidate with one or more other trusts,
partnerships, associations or corporations organized under the laws of the
Commonwealth of Massachusetts or any other state of the United States, to form a
new consolidated trust, partnership, association or corporation under the laws
of which any one of the constituent entities is organized, or (2) merge into one
or more other trusts, partnerships, associations or corporations organized under
the laws of the Commonwealth of Massachusetts or any other state of the United
States, or have one or more such trusts, partnerships, associations or

                                       31
<PAGE>
 
corporations merged into it, any such consolidation or merger to be upon such
terms and conditions as

are specified in an agreement and plan of reorganization entered into by the
Trust, or one or more Series as the case may be, in connection therewith.  The
terms "merge" or "merger" as used herein shall also include the purchase or
acquisition of any assets of any other trust, partnership, association or
corporation which is an investment company organized under the laws of the
Commonwealth of Massachusetts or any other state of the United States.  Any such
consolidation or merger shall require the approval of a Majority Shareholder
Vote of each Series affected thereby.

     Shareholders shall have no right to demand payment for their shares or to
any other rights of dissenting shareholders in the event the Trust or any Series
participates in any transaction which would give rise to appraisal or
dissenters' rights by a shareholder of a corporation organized under Chapter
156B of the General Laws of the Commonwealth of Massachusetts.

     Section 10.4  Amendment Procedure.  All rights granted to the Shareholders
under this Declaration are granted subject to the reservation of the right to
amend this Declaration as herein provided, except that no amendment shall repeal
the limitations on personal liability of any Shareholder or Trustee or repeal
the prohibition of assessment upon the Shareholders without the express consent
of each Shareholder or Trustee involved.  Subject to the foregoing, the
provisions of this Declaration (whether or not related to the rights of
Shareholders) may be amended at any time, so long as such amendment does not
adversely affect the rights of any Shareholder with respect to which such
amendment is or purports to be applicable and so long as such amendment is not
in contravention of applicable law, including the 1940 Act, by an instrument in
writing signed by a majority of the then Trustees (or by an officer of the Trust
pursuant to the vote of a majority of such Trustees).  Any amendment to this
Declaration that adversely affects the rights of Shareholders may be adopted at
any time by an instrument in writing signed by a majority of the then Trustees
(or by an officer of the Trust pursuant to a vote of a majority of such
Trustees) when authorized to do so by the vote of a majority of the Shares
entitled to vote.  Subject to the foregoing, any such amendment shall be
effective as provided in the instrument containing the terms of such amendment
or, if there is no provision therein with respect to effectiveness, upon the
execution of such instrument and of a certificate (which may be a part of such
instrument) executed by a Trustee or officer of the Trust to the effect that
such amendment has been duly adopted.

     Section 10.5  Incorporation.  With the approval of the holders of a
majority of the Shares, the Trustees may cause to be organized or assist in
organizing a corporation or corporations under the laws of any jurisdiction or
any other trust, partnership, association or other organization to take over all
of the

                                       32
<PAGE>
 
Trust Property or to carry on any business in which the Trust shall directly or
indirectly have any interest, and to sell, convey and transfer the Trust
Property to any such corporation, trust, association or organization in exchange
for the shares or securities thereof or otherwise, and to lend money to,
subscribe for the Shares or securities of, and enter into any contracts with any
such corporation, trust, partnership, association or organization, or any
corporation, trust, partnership,

association or organization in which the Trust holds or is about to acquire
shares or any other interest.  The Trustees may also cause a merger or
consolidation between the Trust or any successor thereto and any such
corporation, trust, partnership, association or other organization if and to the
extent permitted by law, as provided under the law then in effect.  Nothing
contained herein shall be construed as requiring approval of Shareholders for
the Trustees to organize or assist in organizing one or more corporations,
trusts, partnerships, associations or other organizations and selling, conveying
or transferring a portion of the Trust Property to such organizations or
entities.

                                   ARTICLE XI

                                 Miscellaneous

     Section 11.1  Filing.  This Declaration and any amendment hereto shall be
filed in the office of the Secretary of the Commonwealth of Massachusetts and in
such other places as may be required under the laws of Massachusetts and also
may be filed or recorded in such other places as the Trustees deem appropriate.
Each amendment so filed shall be accompanied by a certificate signed and
acknowledged by a Trustee or officer stating that such action was duly taken in
a manner provided herein, and unless such amendment or such certificate sets
forth some later time for the effectiveness of such amendment, such amendment
shall be effective upon its filing.  A restated Declaration, containing the
original Declaration and all amendments theretofore made, may be executed from
time to time by a majority of the Trustees and shall, upon filing with the
Secretary of the Commonwealth of Massachusetts, be conclusive evidence of all
amendments contained therein and may thereafter be referred to in lieu of the
original Declaration and the various amendments thereto.

     Section 11.2  Resident Agent.  The Trust shall maintain a resident agent in
the Commonwealth of Massachusetts, which agent shall initially be CT Corporation
System, 2 Oliver Street, Boston, Massachusetts 02109.  The Trustees may
designate a successor resident agent, provided, however, that such appointment
shall not become effective until written notice thereof is delivered to the
office of the Secretary of the Commonwealth of Massachusetts.

     Section 11.3  Governing Law.  This Declaration is executed by the Trustees
and delivered in the Commonwealth of Massachusetts and with reference to the
laws thereof, and the rights of

                                       33
<PAGE>
 
all parties and the validity and construction of every provision hereof shall be
subject to and construed according to the laws of said Commonwealth.

     Section 11.4  Counterparts.  This Declaration may be simultaneously
executed in several counterparts, each of which shall be deemed to be an
original, and such counterparts, together, shall constitute one and the same
instrument, which shall be sufficiently evidenced by any such original
counterpart.

     Section 11.5  Reliance by Third Parties.  Any certificate executed by an
individual who, according to the records of the Trust or of any recording office
in which this Declaration may be recorded, appears to be a Trustee hereunder,
certifying to:  (a) the number or identity of Trustees or Shareholders; (b) the
name of the Trust or any Series thereof; (c) the due authorization of the
execution of any instrument or writing; (d) the form of any vote passed at a
meeting of Trustees or Shareholders; (e) the fact that the number of Trustees or
Shareholders present at any meeting or executing any written instrument
satisfies the requirements of this Declaration; (f) the form of any By-laws
adopted by or the identity of any officers elected by the Trustees; (g) the
existence of any fact or facts which in any manner relate to the affairs of the
Trust or any Series or Class; or (h) the establishment of any Series or Class,
shall be conclusive evidence as to the matters so certified in favor of any
person dealing with the Trustees and their successors.

     Section 11.6  Provisions in Conflict with Law or Regulations.

          (a)  The provisions of this Declaration are severable, and if the
               Trustees shall determine, with the advice of counsel, that any of
               such provisions is in conflict with the 1940 Act, the regulated
               investment company provisions of the Internal Revenue Code or
               with other applicable laws and regulations, the conflicting
               provision shall be deemed never to have constituted a part of
               this Declaration; provided, however, that such determination
               shall not affect any of the remaining provisions of this
               Declaration or render invalid or improper any action taken or
               omitted prior to such determination.

          (b)  If any provision of this Declaration shall be held invalid or
               unenforceable in any jurisdiction, such invalidity or
               unenforceability shall attach only to such provision in such
               jurisdiction and shall not in any manner affect such provision in
               any other jurisdiction or any other provision of this Declaration
               in any jurisdiction.

Trustees.

executed as of the ____day of _________, 1993.

                        WRITTEN INSTRUMENT AMENDING THE
                             AMENDED AND RESTATED
                       AGREEMENT AND DECLARATION OF TRUST
                     OF PIMCO ADVISORS INSTITUTIONAL FUNDS


     The undersigned, being a majority of the Trustees of PIMCO Advisors
Institutional Funds, a Massachusetts business trust, (the "Trust") acting
pursuant to Section 6.2.1 of the Amended and Restated Agreement and Declaration
of Trust, dated May 7, 1993, and subsequently amended on July 15, 1993 and
October 29, 1993, (the "Declaration of Trust"), hereby amend the Declaration of
Trust by dividing the Shares of each Series into three Classes designated as
"Institutional Class," "Benefit Plan Class," and "Administrative Class," by
designating all previously issued and outstanding Shares as Institutional Class
Shares, and by assigning the following relative rights and preferences to each
Class:

     Each Class of a Series shall be identical to each other Class of that
Series except as follows:

     (a)  Each Class shall bear the expenses, costs, charges, and liabilities
          relating to any agreements or arrangements entered into by or on
          behalf of the Trust pursuant to which an organization or other person
          agrees to provide services with respect to that Class but not with
          respect to any other Class or Classes of the Trust, as well as any
          other expenses, costs, charges, and liabilities directly attributable
          to a Class which the Trustees determine should be borne solely by that
          Class; and

     (b)  A Class shall not bear the expenses, costs, charges, and liabilities
          relating to any agreements or arrangements entered into by or on
          behalf of the Trust pursuant to which an organization or other person
          agrees to provide services with respect to any other Class or Classes
          of the Trust, nor any other expenses, costs, charges, or liabilities
          directly attributable to shares of any other Class or Classes of the
          Trust which the Trustees determine should be borne exclusively by such
          other Class or Classes; and

     (c)  The dividends and distributions with respect to each Class of a Series
          shall be in such amount as may be declared from time to time by or
          under the direction of the Trustees, and such dividends and
          distributions may vary from dividends and distributions with respect
          to other Classes of that Series to reflect differing allocations of
          the expenses, costs, charges, or liabilities of the Trust among the
          holders of the Classes of Shares of that Series and to equalize the
          net asset value per Share of its Classes, to such extent and for such
          purposes as the Trustees may deem appropriate.

                                       37
<PAGE>
 
     (d) The Shareholders of each Class of each Series shall have (i) exclusive
voting rights with respect to matters on which the Shareholders of the Class
shall be entitled to exclusive voting rights under applicable federal or state
law and on any matters affecting only that Class and (ii) no voting rights with
respect to matters on which the Shareholders of another Class of that Series or
another Series shall be entitled to exclusive voting rights under applicable
federal or state law or on any matters affecting only another Class or Classes.

          IN WITNESS WHEREOF, the undersigned have caused these presents to be
executed as of the __ day of March, 1994.
