                          AGREEMENT AND PLAN OF MERGER

          AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), dated as of June 16,
2000, by and among United Asset Management Corp., a Delaware corporation (the
"COMPANY"), Old Mutual plc, a public limited company incorporated in England and
Wales ("PARENT"), and OM Acquisition Corp., a Delaware corporation and a wholly
owned subsidiary of Parent ("PURCHASER").

                                    RECITALS

            WHEREAS, it is proposed that Purchaser acquire all of the issued and
outstanding shares of Common Stock, par value $0.01 per share, of the Company
(the "COMMON SHARES"), other than Common Shares beneficially owned by Parent or
Purchaser (references to Parent shall, where the context so requires, be deemed
to refer to Purchaser as well);

            WHEREAS, it is proposed that Purchaser will make a cash tender offer
(the "OFFER") in compliance with Section 14(d)(1) of the Securities Exchange Act
of 1934, as amended (together with the rules and regulations promulgated
thereunder, the "EXCHANGE ACT") to acquire all the issued and outstanding Common
Shares, other than Common Shares beneficially owned by Parent or Purchaser, for
$25 per Common Share (the "BASE OFFER PRICE", and, such amount, as it may be
adjusted in accordance with Section 1.4 hereof, or any greater amount per share
paid pursuant to the Offer, the "OFFER PRICE"), net to the seller in cash, upon
the terms and subject to the conditions of this Agreement and Annex I hereto;
and that the Offer will be followed by the merger (the "MERGER") of Purchaser
with and into the Company, with the Company being the surviving corporation, in
accordance with the Delaware General Corporation Law ("DGCL"), pursuant to which
each issued and outstanding Common Share not beneficially owned by Parent will
be converted into the right to receive the Offer Price upon the terms and
subject to the conditions provided herein and in Annex I hereto;

            WHEREAS, the Company, Parent and Purchaser desire to make certain
representations, warranties, covenants and agreements in connection with this
Agreement;

            WHEREAS, the Board of Directors of the Company (the "COMPANY BOARD")
has received the oral opinion of Goldman, Sachs & Co. (the "FINANCIAL ADVISOR"),
and which oral opinion will be promptly confirmed in writing, to the effect
that, based on, and subject to, the various assumptions and qualifications set
forth in such opinion, as of the date of such opinion, the Offer Price to be
received by the holders of the Common Shares in the Offer and the Merger is fair
from a financial point of view to such holders (the "FAIRNESS OPINION"); and

            WHEREAS, the Company Board has unanimously approved this Agreement
and the Offer, determined that this Agreement, the Offer, the Merger and the
other transactions contemplated hereby are advisable and in the best interests
of the Company and its stockholders and adopted the plan of merger set forth
herein;

            WHEREAS, the Boards of Directors of Parent and Purchaser have
approved this Agreement and the Offer, determined that this Agreement, the
Offer, the Merger and the other transactions contemplated hereby are advisable
and in the best interests of Parent and Purchaser and adopted the plan of merger
set forth herein;


<PAGE>

            NOW, THEREFORE, in consideration of the premises, and of the
representations, warranties, covenants and agreements contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, intending to be legally bound hereby, the parties hereto
agree as follows:

                                    ARTICLE I

                                    THE OFFER

            Section 1.1.    THE OFFER.

            (a)  Provided that this Agreement shall not have been terminated in
accordance with Article VII and subject to the conditions set forth in Annex I
hereto (the "TENDER OFFER CONDITIONS"),, not later than 30 calendar days
following the date hereof, Purchaser shall, and Parent shall cause Purchaser to,
commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer to
purchase all outstanding Common Shares at the Offer Price. The obligation of
Purchaser to accept for payment any Common Shares tendered pursuant to the Offer
will be subject only to the satisfaction of the Tender Offer Conditions. The
initial scheduled expiration date of the Offer shall be the 20th business day
following the date of commencement of the Offer (determined using Rule 14d-2
under the Exchange Act).

            (b) Purchaser expressly reserves the right to waive any Tender Offer
Condition, to increase the Offer Price and to make any other changes in the
terms and conditions of the Offer. Notwithstanding the foregoing, without the
prior written consent of the Company, Purchaser shall not (i) impose conditions
to the Offer in addition to the Tender Offer Conditions, (ii) modify or amend
the Tender Offer Conditions or any other term of the Offer in a manner adverse
to the holders of Common Shares, (iii) reduce the number of Common Shares
subject to the Offer, (iv) reduce the Minimum Tender Condition (as defined in
Annex I), (v) reduce the Offer Price, (vi) except as provided in the following
sentence, extend the Offer if all of the Tender Offer Conditions are satisfied
or waived, or (vii) change the form of consideration payable in the Offer.
Notwithstanding the foregoing, Purchaser may, in accordance with Applicable Law,
and without the consent of the Company, extend the Offer at any time, and from
time to time, (i) beyond the initial scheduled expiration date or any subsequent
scheduled expiration of the Offer if, at such scheduled expiration of the Offer,
any of the Tender Offer Conditions shall not be satisfied or, to the extent
permitted by this Agreement, waived (and, so long as this Agreement is in
effect, the Offer has been commenced and the Tender Offer Conditions have not
been satisfied or waived, Purchaser shall, and Parent shall cause Purchaser to,
cause the Offer not to expire, and shall extend the Offer from time to time
until the Termination Date (as defined in Section 7.2(a)(i)), subject, however,
to Purchaser's and Parent's rights of termination under this Agreement) or (ii)
for any period required by any rule, regulation or interpretation of the
Securities and Exchange Commission (the "SEC") or the staff thereof applicable
to the Offer. Unless otherwise agreed by the Purchaser and the Company, any
extension of the Offer pursuant to the preceding sentence or clause (i) of the
second preceding sentence of this Section 1.1(b) shall not exceed the lesser of
five business days or such fewer number of days that Purchaser reasonably
believes are necessary to cause the Tender Offer Conditions to be satisfied.
Purchaser may in addition, provided that doing so shall not require any
extension of what would otherwise be the final expiration date of the Offer,
provide a "subsequent offering period" (as contemplated by Rule 14d-11


                                       -2-
<PAGE>

under the Exchange Act) of not less than three business days and not more than
ten business days following its acceptance for payment of Common Shares in the
Offer. Parent and Purchaser shall comply with the obligations respecting prompt
payment and announcement under the Exchange Act, and, without limiting the
generality of the foregoing, Purchaser shall, and Parent shall cause Purchaser
to, pay for any and all Common Shares validly tendered and not withdrawn
pursuant to the Offer that Purchaser becomes obligated to purchase pursuant to
the Offer within two business days following acceptance for payment of any and
all such Common Shares pursuant to the Offer.

         Section 1.2.  ACTIONS BY PARENT AND PURCHASER.

         (a)  On the date of commencement of the Offer, Parent and Purchaser
shall file with the SEC a Tender Offer Statement on Schedule TO, including all
exhibits thereto (together with all amendments and supplements thereto, the
"SCHEDULE TO") with respect to the Offer, the Merger and the other transactions
contemplated hereby. The Schedule TO shall contain or incorporate by reference
an offer to purchase (the "OFFER TO PURCHASE") and forms of the related letter
of transmittal and any related documents (the Schedule TO, the Offer to Purchase
and such other documents, together with all supplements or amendments thereto,
collectively, the "OFFER DOCUMENTS").

         (b)  Parent and Purchaser represent that the Offer Documents shall
comply in all material respects with the requirements of applicable federal
securities laws, including the Exchange Act, on the date filed with the SEC and
on the date first published, sent or given to the Company's stockholders, shall
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that no representation is made by Parent or Purchaser
with respect to information supplied by the Company in writing specifically for
inclusion in the Offer Documents. Each of Parent and Purchaser agrees to correct
promptly, and the Company agrees to notify Parent promptly as to, any
information provided by it for use in the Offer Documents, if and to the extent
such information shall have become false or misleading in any material respect,
and each of Parent and Purchaser further agrees to take all steps necessary to
cause the Offer Documents as so corrected to be filed with the SEC and to be
disseminated to all of the holders of Common Shares, in each case as and to the
extent required by applicable federal securities laws. Parent and Purchaser
agree to provide the Company and its counsel in writing any comments Parent,
Purchaser or their counsel may receive from the SEC or its staff with respect to
the Offer Documents promptly after receipt of such comments. Parent and
Purchaser shall use their respective reasonable best efforts to respond to such
comments promptly and shall provide the Company copies of any written responses
and telephonic notification of any oral responses by Parent, Purchaser or their
counsel.

          Section 1.3.  COMPANY ACTIONS.

          (a)  The Company shall file with the SEC and mail to the holders of
Common Shares, on the date of the filing by Parent and Purchaser of the Offer
Documents, a Solicitation/Recommendation Statement on Schedule 14D-9 (together
with any amendments or supplements thereto, the "SCHEDULE 14D-9") reflecting the
recommendation of the Company Board that holders of Common Shares tender their
Common Shares pursuant to the Offer, and shall dis-


                                       -3-
<PAGE>

seminate the Schedule 14D-9 as required by Rule 14d-9 promulgated under the
Exchange Act. The Schedule 14D-9 will set forth, and the Company hereby
represents that the Company Board, at a meeting duly called and held, has (i)
determined by unanimous vote of its directors, that the Offer and the Merger are
fair to, advisable and in the best interests of the Company and its
stockholders, (ii) approved the Offer and this Agreement and the transactions
contemplated hereby in accordance with the DGCL, (iii) resolved to recommend
acceptance of the Offer and approval of this Agreement by the Company's
stockholders, and (iv) taken all action, if any, necessary to render Section 203
of the DGCL inapplicable to the Offer and the Merger; PROVIDED, HOWEVER, that
such recommendation and approval may be withdrawn, modified or amended to the
extent that the Company Board determines in good faith, after consultation with
outside counsel, that such action is required in the exercise of the Company
Board's fiduciary duties under Applicable Law. The Company further represents
that, prior to the execution hereof, the Financial Advisor has delivered to the
Company Board the Fairness Opinion. The Company further represents and warrants
that it has been authorized by the Financial Advisor to reproduce the written
Fairness Opinion in full (and only in full), and may also include references to
the Fairness Opinion and to the Financial Advisor and its relationship with the
Company (in each case in form and substance as the Financial Advisor shall
reasonably approve in advance), in any statement on Schedule 14D-9 or proxy
statement relating to the transactions contemplated hereby that the Company is
required to file or distribute to its stockholders under the Exchange Act or
other Applicable Law. The Company further represents that it will file such
other documentation and take such other actions as are required by Applicable
Law to effect the purposes of this Agreement. The Company hereby consents to the
inclusion in the Offer Documents of the recommendation of the Company Board
described in this Section 1.3(a).

           (b)  The Schedule 14D-9 will comply in all material respects with the
provisions of applicable federal securities laws, and, on the date filed with
the SEC and on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements made therein, in light of the circumstances under which
they were made, not misleading, except that no representation is made by the
Company with respect to information supplied by Parent or Purchaser in writing
for inclusion in the Schedule 14D-9. Each of the Company, on the one hand, and
Parent and Purchaser, on the other hand, agrees promptly to correct any
information provided by either of them for use in the Schedule 14D-9 if and to
the extent that it shall have become false or misleading, and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and to be disseminated to the holders of
Common Shares, in each case, as and to the extent required by applicable federal
securities laws. The Company agrees to provide Parent and its counsel in writing
any comments the Company may receive from the SEC or its staff with respect to
the Schedule 14D-9 promptly after receipt of such comments. The Company shall
use its reasonable best efforts to respond to such comments promptly and shall
provide Parent copies of any written responses and telephonic notification of
any oral responses by the Company or its counsel.

          (c)  In connection with the Offer, the Company will promptly, or shall
cause its transfer agent to promptly, furnish Purchaser with mailing labels,
security position listings, any non-objecting beneficial owner lists and any
available listing containing the names and addresses of the record holders of
Common Shares as of the most recent practicable date and shall furnish Purchaser
with such additional information (including, but not limited to, updated lists
of


                                      -4-
<PAGE>

holders of Common Shares and their addresses, mailing labels and lists of
security positions and non-objecting beneficial owner lists) and such other
assistance as Purchaser or its agents may reasonably request in communicating
the Offer to the Company's record and beneficial stockholders. Subject to the
requirements of Applicable Law, and except for such steps as are appropriate to
disseminate the Offer Documents and any other documents necessary to consummate
the Offer and the Merger, Parent, Purchaser and their affiliates, associates,
agents and advisors shall use the information contained in any such labels,
listings and files only in connection with the Offer and the Merger, and, if
this Agreement shall be terminated, will deliver to the Company all copies of
such information then in their possession.

          Section 1.4.  ADJUSTMENT TO OFFER PRICE.

          (a)  If Aggregate Client Revenue (as defined in Annex I hereto) as of
the most recent calendar month-end prior to the acceptance by Purchaser of
Common Shares for payment pursuant to the Offer (the "LAST MONTH-END") (such
amount of Aggregate Client Revenue as of the Last Month-End being hereinafter
referred to as the "LME AMOUNT") is less than the Requisite Revenue Percentage
and greater than 75% of Aggregate Client Revenue as of May 31, 2000, the Offer
Price shall be equal to (x) the Base Offer Price multiplied by (y) a quotient,
the numerator of which is the LME amount plus an amount equal to the product of
(A) a percentage equal to 100% less the Requisite Revenue Percentage multiplied
by (B) Aggregate Client Revenue as of May 31, 2000, and the denominator of which
is Aggregate Client Revenue as of May 31, 2000; provided that if (1) the LME
Amount is less than (2) an amount equal to the product of the Requisite Revenue
Percentage multiplied by Aggregate Client Revenue as of May 31, 2000 (the
"REQUISITE AMOUNT") by an amount that is more than 5% of Aggregate Client
Revenue as of May 31, 2000 (such shortfall in excess of Aggregate Client Revenue
as of May 31, 2000, expressed as a percentage of Aggregate Client Revenue as of
May 31, 2000, the "ADDITIONAL REVENUE SHORTFALL"), the Offer Price shall also be
reduced by an additional amount equal to (x) the Base Offer Price multiplied by
(y) the Additional Revenue Shortfall. For the avoidance of doubt, the effect of
the foregoing sentence shall be to reduce the Base Offer Price by 1% for every
1% (measured with respect to Aggregate Client Revenue as of May 31, 2000) by
which the LME Amount is less than the Requisite Amount for the first 5%
(measured with respect to Aggregate Client Revenue as of May 31, 2000) shortfall
of the LME Amount from the Requisite Amount, and 2% for every 1% (measured with
respect to Aggregate Client Revenue as of May 31, 2000) by which the LME Amount
is less than the Requisite Amount for any shortfall of the LME Amount from the
Requisite Amount in excess of the first 5% (measured with respect to Aggregate
Client Revenue as of May 31, 2000).) Notwithstanding the foregoing, if, as of
the Last Month-End, Fund Approval and Client Consent (each as defined below) are
obtained from Clients (as defined below) the Aggregate Client Revenue of which
accounts together represent the Requisite Amount, the Offer Price shall be equal
to the Base Offer Price. If the LME Amount is less than 75% of Aggregate Client
Revenue as of May 31, 2000 and Purchaser waives the conditions set forth in
paragraph (b) of Annex I, the Offer Price shall be adjusted as if the LME Amount
were equal to 75% of Aggregate Client Revenue as of May 31, 2000. For the
purposes of this Agreement, the "REQUISITE REVENUE PERCENTAGE" shall be equal to
(x) 90% less (y) the product of 1.5% times the number of calendar month-ends
between the date hereof and the Last Month-End, including the Last Month-End (so
that, for instance, if the Last Month-End shall be August 31, 2000, the
Requisite Revenue Percentage would be 85.5%).


                                      -5-
<PAGE>

          (b)  In addition, the Offer Price shall also be subject to reduction
by an amount equal to a quotient equal to one-half of Special Costs (as defined
in Section 1.5 of the Company Disclosure Letter) divided by the total number of
outstanding Common Shares (determined on a fully diluted basis, after giving
effect to the exercise or conversion of all options, rights and securities
exercisable or convertible into Common Shares).

                                   ARTICLE II

                                   THE MERGER

          Section 2.1.  THE MERGER. Upon the terms and subject to the
satisfaction or waiver of the conditions hereof, and in accordance with the
applicable provisions of this Agreement and the DGCL, at the Effective Time (as
defined below) Purchaser shall be merged with and into the Company. Following
the Merger, the separate corporate existence of Purchaser shall cease, and the
Company shall continue as the surviving corporation (the "SURVIVING
CORPORATION").

         Section 2.2.  EFFECTIVE TIME. As soon as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the Company
and Purchaser shall cause a certificate of merger (the "CERTIFICATE OF MERGER")
to be executed, verified and filed with, and delivered to, in the manner
required by the DGCL, the Secretary of State of the State of Delaware, and the
parties shall take such other and further actions as may be required by
Applicable Law to make the Merger effective. The Merger shall become effective
at such time as the Certificate of Merger is duly filed with the Secretary of
State of the State of Delaware or at such later time as is agreed to by the
parties hereto and as specified in the Certificate of Merger (the "EFFECTIVE
TIME"). Prior to the filing referred to in this Section 2.2, the closing will be
held at the offices of Weil, Gotshal & Manges LLP, 767 Fifth Avenue, New York,
New York 10153 (or such other place as the parties may agree) for the purpose of
confirming all of the foregoing.

         Section 2.3.  EFFECTS OF THE MERGER. From and after the Effective Time,
the Merger shall have the effects set forth in the DGCL. Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time, all the
properties, rights, privileges, powers and franchises of the Company and
Purchaser shall vest in the Surviving Corporation, and all debts, liabilities
and duties of the Company and Purchaser shall become the debts, liabilities and
duties of the Surviving Corporation.

        Section 2.4.  CERTIFICATE OF INCORPORATION AND BY-LAWS OF THE SURVIVING
CORPORATION. (a) The certificate of incorporation of Purchaser as in effect
immediately prior to the Effective Time shall be the articles of incorporation
of the Surviving Corporation until thereafter amended in accordance with the
provisions thereof and Applicable Law, except that Article I of the certificate
of incorporation of the Surviving Corporation shall read until thereafter
amended: "The name of the corporation (the "CORPORATION") is: United Asset
Management Corporation."

        (b)  The by-laws of Purchaser in effect at the Effective Time shall be
the by-laws of the Surviving Corporation until amended in accordance with the
provisions thereof, the articles of incorporation and Applicable Law.

        Section 2.5.  DIRECTORS. The directors of Purchaser immediately prior to

accordance with the articles of incorporation and the by-laws of the Surviving
Corporation.

        Section 2.6.  OFFICERS. The officers of Purchaser immediately prior to
the Effective Time shall be the initial officers of the Surviving Corporation

accordance with the articles of incorporation and the by-laws of the Surviving
Corporation.

        Section 2.7.  CONVERSION OF COMMON SHARES. At the Effective Time, by
virtue of the Merger and without any action on the part of the holders thereof,
each Common Share issued and outstanding immediately prior to the Effective Time
(other than (i) any Common Shares held by Parent, Purchaser, any direct or
indirect wholly owned Subsidiary of Parent or Purchaser (the "PARENT SHARES"),
or by any wholly owned Subsidiary of the Company, which Common Shares shall
remain outstanding, and (ii) Dissenting Shares (as defined herein)), shall by
virtue of the Merger be cancelled and retired and shall be converted into the
right to receive pursuant to Section 3.2 the Offer Price, payable to the holder
thereof, without interest thereon, upon surrender of the certificate formerly
representing such Common Share or any replacement certificates representing such
Common Shares as may be obtained from the transfer agent of the Company.

        Section 2.8. CONVERSION OF PURCHASER COMMON STOCK. Purchaser has
outstanding 10 shares of common stock, par value $0.01 per share, all of which
shares are entitled to vote with respect to approval and adoption of this
Agreement. At the Effective Time, each share of common stock, par value $0.01
per share, of Purchaser issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the holder thereof, be converted into and become one validly issued, fully
paid and non-assessable share of common stock, par value $0.01 per share, of the
Surviving Corporation.

         Section 2.9. OPTIONS; STOCK PLANS.

        (a)  Prior to the acceptance for payment of Common Shares in the Offer,
the Company Board (or, if appropriate, any committee thereof) shall adopt
appropriate resolutions and take all other actions necessary to provide for the
cancellation, effective at the Effective Time, of all the outstanding Company
Options heretofore granted under any Stock Plan (as defined below) and
Stand-Alone Option Plans (as defined below). Such cancellation shall occur
without any payment therefor except as provided in Section 5.9.

        (b)  The Company shall take all actions necessary to provide that,
effective as of the Effective Time, (i) the Option Plan and the Stand-Alone
Option Plans shall be terminated, (ii) the provisions in the Deferral Plans and
any other plan, program or arrangement providing for the issuance or grant of
any other interest in respect of the capital stock of the Company shall be
deleted, and (iii) no holder of Company Options or Warrants (as defined below)
will have any


                                      -7-
<PAGE>

right to receive any shares of capital stock of the Company or, if applicable,
the Surviving Corporation, upon exercise of any Company Option or Warrant.

          Section 2.10.  STOCKHOLDERS' MEETING.

          (a)  If required by Applicable Law in order to consummate the Merger,
the Company, acting through the Company Board, shall, in accordance with
Applicable Law, and provided that this Agreement shall not have been terminated:

                (i)   duly call, give notice of, convene and hold a special
          meeting of its stockholders (the "SPECIAL MEETING") to be held as soon
          as practicable following the acceptance for payment of Common Shares
          by Purchaser pursuant to the Offer for the purpose of considering and
          taking action upon this Agreement;

                (ii)  together with Parent, prepare and file with the SEC a
          preliminary proxy statement soliciting Company stockholder approval of
          the Merger and this Agreement, and use reasonable best efforts to
          obtain and furnish the information required to be included by the SEC
          in the Proxy Statement (as defined below) and, after consultation with
          each other, to respond as soon as practicable to any comments made by
          the SEC with respect to the preliminary proxy statement and cause a
          definitive proxy statement (the "PROXY STATEMENT"), which the parties
          agree shall comply as to form in all material respects with all
          Applicable Law, to be mailed to its stockholders at the earliest
          practicable date following expiration or termination of the Offer; and

                (iii) include in the Proxy Statement (x) the recommendation of
          the Company Board that stockholders of the Company vote in favor of
          the approval of the Merger and of this Agreement (except as set forth
          in the proviso to Section 1.3(a)) and (y) the Fairness Opinion in
          accordance with the provisions of Section 1.3(a).

          (b) Parent agrees that it will vote, or cause to be voted, all Common
Shares then owned by it, Purchaser or any of Parent's other Subsidiaries in
favor of the approval of the Merger and of this Agreement.

          (c) Whenever any event occurs which is required to be set forth in an
amendment or supplement to the Proxy Statement, Parent or the Company, as the
case may be, shall promptly inform the other of each such occurrence and
cooperate in the filing with the SEC and/or mailing to the Company stockholders
of such amendment or supplement. Each of the parties agrees that the information
provided by it for inclusion in the Proxy Statement and each amendment or
supplement thereto, at the time of mailing thereof and at the time of the
Special Meeting, will not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. If, at any time prior to the Effective Time, any information
pertaining to one of the parties or, to such party's knowledge, any of its
affiliates or its officers or directors, contained in or omitted from the Proxy
Statement makes statements contained therein materially false or misleading,
such party shall promptly so advise the other parties and provide such other
parties with the information necessary to make the statements contained therein
not false or misleading. In the event of such advice being given pursuant to the


                                      -8-
<PAGE>

preceding sentence, the Company and Parent shall cooperate to file promptly with
the SEC (after reasonable opportunity for Parent and the Company to review and
comment thereon) any required amendments or supplements to the Proxy Statement
and, to the extent required by Applicable Law, disseminate such amendments or
supplements to the Company stockholders.

        Section 2.11.  MERGER WITHOUT MEETING OF STOCKHOLDERS. Notwithstanding
Section 2.10, in the event that Purchaser shall acquire pursuant to the Offer
such number of Common Shares which, when aggregated with the number of Common
Shares otherwise beneficially owned by Parent, represents 90% of the total
number of outstanding Common Shares on the date of, and after giving effect to,
such acquisition, the parties hereto agree to take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after the
acceptance for payment of Common Shares by Purchaser pursuant to the Offer
without a meeting of stockholders of the Company, in accordance with Section 253
of the DGCL.

                                 ARTICLE III

                  DISSENTING SHARES; PAYMENT FOR COMMON SHARES

        Section 3.1.  DISSENTING SHARES. Notwithstanding anything in this
Agreement to the contrary, Common Shares outstanding immediately prior to the
Effective Time that are held by stockholders (i) who shall have neither voted
for approval and adoption of this Agreement and the Merger nor consented thereto
in writing and (ii) who shall be entitled to and who shall have demanded
properly in writing appraisal for such Common Shares in accordance with Section
262 of the DGCL ("DISSENTING SHARES"), shall not be converted into the right to
receive the Offer Price at or after the Effective Time unless and until the
holder of such Common Shares fails to perfect, withdraws or otherwise loses such
holder's right to appraisal. If a holder of Dissenting Shares shall withdraw (in
accordance with Section 262(k) of the DGCL) his or her demand for such appraisal
or shall become ineligible for such appraisal, then, as of the Effective Time or
the occurrence of such event, whichever last occurs, such holder's Common Shares
shall cease to be Dissenting Shares and shall be converted into and represent
the right to receive the Offer Price, without interest thereon. The Company
shall give Parent prompt notice of any written demands for appraisal received by
the Company and the opportunity to participate in all negotiations and
proceedings with respect to demands for appraisal. The Company shall not, except
with the prior written consent of Parent, make any payment with respect to, or
offer to settle or settle, or otherwise negotiate, any such demands.

        Section 3.2.   PAYMENT FOR COMMON SHARES.

        (a)  Prior to the Effective Time, Purchaser shall designate a bank or
trust company reasonably acceptable to the Company to act as paying agent (the
"PAYING AGENT") in effecting the payment of the Offer Price in respect of
certificates that, immediately prior to the Effective Time, represent Common
Shares (the "CERTIFICATES") entitled to payment of the Offer Price pursuant to
Section 2.7. At the Effective Time, Parent or Purchaser shall deposit, or cause
to be deposited, in trust, upon terms (including as to the release of such funds
to holders of Common Shares upon consummation of the Merger) reasonably
acceptable to the Company,


                                      -9-
<PAGE>

with the Paying Agent the aggregate Offer Price to
which holders of Common Shares shall be entitled at the Effective Time pursuant
to Section 2.7.

        (b)  Promptly after the Effective Time, the Paying Agent shall mail to
each record holder of Certificates a form of letter of transmittal which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates to the
Paying Agent and instructions for use in surrendering such Certificates and
receiving the Offer Price in respect thereof. Upon the surrender of each such
Certificate, together with a duly executed letter of transmittal and any other
required documents, the Paying Agent shall, as soon as practicable, pay the
holder of such Certificate an amount equal to the product of (x) the Offer Price
multiplied by (y) the number of Common Shares formerly represented by such
Certificate, in consideration therefor, and such Certificate shall forthwith be
cancelled. Until so surrendered, each such Certificate (other than Certificates
representing Common Shares held by Parent or Purchaser, any wholly owned
Subsidiary of Parent or Purchaser, in the treasury of the Company or by any
wholly owned Subsidiary of the Company or Dissenting Shares) shall represent
solely the right to receive the aggregate Offer Price relating thereto. No
interest or dividends shall be paid or accrued on the Offer Price. If the Offer
Price (or any portion thereof) is to be delivered to any individual,
corporation, trust, association, unincorporated association, estate,
partnership, joint venture, limited liability company, Governmental Entity (as
defined in Section 4.1) or other legal entity (each, a "PERSON"), other than the
Person in whose name the Certificate surrendered is registered, it shall be a
condition to such right to receive such Offer Price that the Certificate so
surrendered shall be properly endorsed or otherwise be in proper form for
transfer, that the signatures on the Certificate shall be properly guaranteed,
and that the Person surrendering such Common Shares shall pay to the Paying
Agent any transfer or other Taxes required by reason of the payment of the Offer
Price to a Person other than the registered holder of the Certificate
surrendered, or shall establish to the satisfaction of the Paying Agent that
such Taxes have been paid or are not applicable. In the event any Certificate
shall have been lost, stolen or destroyed, the Paying Agent shall be required to
pay the full Offer Price in respect of any Common Shares represented by such
Certificate; however, Parent may require the owner of such lost, stolen or
destroyed Certificate to execute and deliver to the Paying Agent a form of
affidavit claiming such Certificate to be lost, stolen or destroyed in form and
substance reasonably satisfactory to Parent, and the posting by such owner of a
bond in such amount as Parent may determine is reasonably necessary as indemnity
against any claim that may be made against Parent or the Paying Agent.

        (c)  Promptly following the date which is 120 days after the Effective
Time, the Paying Agent shall deliver to the Surviving Corporation all cash,
Certificates and other documents in its possession relating to the transactions
contemplated hereby, and the Paying Agent's duties shall terminate. Thereafter,
each holder of a Certificate may surrender such Certificate to the Surviving
Corporation and (subject to applicable abandoned property, escheat and similar
Applicable Law) receive in consideration therefor the aggregate Offer Price
relating thereto, without any interest or dividends thereon, except as required
under Applicable Law. Notwithstanding the foregoing, none of Parent, Purchaser,
the Company or the Paying Agent shall be liable to any Person in respect of any
cash delivered to a public official pursuant to any applicable abandoned
property, escheat or similar Applicable Law. If any Certificates shall not have
been surrendered immediately prior to such date on which any payment pursuant to
this Article III would otherwise escheat to or become the property of any
Governmental Entity, the


                                      -10-
<PAGE>

cash payment in respect of such Certificate shall, to the extent permitted by
Applicable Law, become the property of the Surviving Corporation, free and clear
of all claims or interests of any Person previously entitled thereto.

        (d)  Immediately prior to the Effective Time, the stock transfer books
of the Company shall be closed, and, after the Effective Time, there shall be no
transfers on the stock transfer books of the Surviving Corporation of any Common
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation or
the Paying Agent, they shall be surrendered and cancelled in return for the
payment of the aggregate Offer Price relating thereto, as provided in this
Article III.

        (e)  From and after the Effective Time, the holders of Certificates
evidencing ownership of Common Shares outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such Common Shares
except as otherwise provided herein or by Applicable Law. Such holders shall
have no rights, after the Effective Time, with respect to such Common Shares
except to surrender such Certificates in exchange for the Offer Price pursuant
to this Agreement or to perfect any rights of appraisal as a holder of
Dissenting Shares that such holders may have pursuant to Section 262 of the
DGCL.

        (f)  Each of Parent, Purchaser, the Paying Agent and the Surviving
Corporation shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder Common Shares such
amounts as it is required to deduct and withhold with respect to the making of
such payment under the Internal Revenue Code of 1986, as amended, and any
successor thereto (the "CODE") and the rules and regulations promulgated
thereunder, or any provision of state, local or foreign Tax Law. To the extent
that amounts are so withheld by Parent, Surviving Corporation, Purchaser or
Paying Agent, as the case may be, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the Common
Shares in respect of which such deduction and withholding was made by Parent,
Surviving Corporation, Purchaser or Paying Agent, as the case may be.

                                    ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

        Section 4.1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Except as
set forth in the disclosure letter delivered to Parent by the Company on or
prior to entering into this Agreement (the "COMPANY DISCLOSURE LETTER"), the
Company hereby represents and warrants to Parent that (it being understood that
the words "to the Knowledge of the Company" or "the Company's Knowledge" and any
words of similar import shall mean the actual knowledge of the persons whose
names are set forth in Section 4.1(a) of the Company Disclosure Letter):

        (a)  ORGANIZATION, GOOD STANDING AND QUALIFICATION. Each of the Company
and its Subsidiaries (as defined below) is a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
organization and has all requisite corporate or similar power and authority to
own and operate its properties and assets and to carry on its business as
presently conducted and is qualified to do business and is in good standing as a
foreign corporation in each jurisdiction where the ownership or operation of its
properties or


                                      -11-
<PAGE>

conduct of its business requires such qualification, except where the failure to
be so qualified or in good standing, when taken together with all other such
failures, is not, individually or in the aggregate, reasonably likely to have a
Company Material Adverse Effect (as defined below). The Company has made
available to Parent complete and correct copies of the Company's and its
material Subsidiaries' (including all active, directly owned, domestic
Subsidiaries') charters and bylaws, each as amended to date. The Company's and
its material Subsidiaries' charters and bylaws made available are in full force
and effect. Section 4.1(a) of the Company Disclosure Letter contains, as
qualified therein, a correct and complete list of all Subsidiaries of the
Company.

            As used in this Agreement, the term (x) "SUBSIDIARY" means, with
respect to the Company or Parent, as the case may be, any Person (other than
pooled investment vehicles that constitute Exempt Fund Clients), of which at
least a majority of the securities or ownership interests having by their terms
ordinary voting power to elect a majority of the Board of Directors or other
persons performing similar functions, or a general partner interest or managing
membership interest, is directly or indirectly owned or controlled by such party
or by one or more of its respective Subsidiaries and (y) "COMPANY MATERIAL
ADVERSE EFFECT" means a material adverse effect on the financial condition,
operations, properties, business or results of operations of the Company and its
Subsidiaries taken as a whole (other than any change or effect arising out of
(A) a decline or deterioration in the economy or the capital markets in general
or the markets in which the Company and its Subsidiaries operate, or (B) this
Agreement or the transactions contemplated hereby or the announcement thereof)
or an effect which is reasonably likely to prevent, materially delay or
materially impair the ability of the Company to consummate the transactions
contemplated by this Agreement or to carry on the business of the Company and
its Subsidiaries, taken as a whole, substantially in the same manner as
currently conducted.

        (b)  CAPITAL STRUCTURE. The authorized stock of the Company consists of
200,000,000 Common Shares, of which 56,525,502 Common Shares were outstanding as
of the close of business on June 15, 2000, and 5,000,000 shares of preferred
stock, par value $1.00 per share, of which none were outstanding as of the date
hereof. All of the outstanding Common Shares have been duly authorized and are
validly issued, fully paid and nonassessable. The Company has no commitments to
issue or deliver Common Shares except that, as of June 15, 2000, there were
16,924,597 Common Shares reserved for issuance pursuant to the United Asset
Management Corporation Second Amended and Restated 1994 Stock Option Plan (the
"OPTION PLAN)", the United Asset Management Corporation Stock Option Deferral
Plan and the United Asset Management Corporation Deferred Compensation Plan
(such two plans, the "DEFERRAL PLANS") and the Stand-Alone Option Plans (the
"STAND-ALONE OPTION PLANS") identified in Section 4.1(b) of the Company
Disclosure Letter (the Stand-Alone Option Plans, together with the Option Plan
and the Deferral Plans, the "STOCK PLANS"), and except for shares issuable
pursuant to outstanding warrants (the "WARRANTS"). Section 4.1(b) of the Company
Disclosure Letter contains a correct and complete list of the Warrants, each
outstanding option to purchase Common Shares under the Stock Plans (each a
"COMPANY OPTION"), including the holder, date of grant, exercise price and
number of Common Shares subject thereto. Each of the outstanding shares of
capital stock or other securities of each of the Company's Subsidiaries is duly
authorized, validly issued, fully paid and nonassessable and owned by the
Company or by a direct or indirect wholly owned subsidiary of the Company, free
and clear of any lien, pledge, security interest, claim or other encumbrance.
Except as set forth above, there are no Common Shares authorized, re-



                                      -12-
<PAGE>

served, issued or outstanding and there are no preemptive or other outstanding
rights, subscriptions, options, warrants, stock appreciation rights, redemption
rights, repurchase rights, registration rights, convertible securities or other
agreements, arrangements or commitments of any character relating to the issued
or unissued share capital or other ownership interest of the Company or any of
its Subsidiaries or any other securities or obligations convertible or
exchangeable into or exercisable for, or giving any Person a right to subscribe
for or acquire, any securities of the Company or its Subsidiaries, and no
securities evidencing such rights are authorized, issued or outstanding. Neither
the Company nor any of its Subsidiaries has outstanding any bonds, debentures,
notes or other obligations the holders of which have the right to vote (or
convertible into or exercisable for securities having the right to vote) with
the stockholders of the Company or any of its Subsidiaries on any matter
("VOTING DEBT").

        (c)  CORPORATE AUTHORITY; APPROVAL AND FAIRNESS.

             (i)   The Company has all requisite corporate power and authority
          and has taken all corporate action necessary in order to execute,
          deliver and perform its obligations under this Agreement and to
          consummate, subject only to approval of the Merger by the holders of a
          majority of the outstanding Common Shares entitled to vote on the
          matter (the "COMPANY REQUISITE VOTE"), the Merger. This Agreement is a
          valid and binding agreement of the Company enforceable against the
          Company in accordance with its terms, subject to bankruptcy,
          insolvency, fraudulent transfer, reorganization, moratorium and
          similar laws of general applicability relating to or affecting
          creditors' rights and to general equity principles (the "BANKRUPTCY
          AND EQUITY EXCEPTION").

             (ii) The Board of Directors of the Company (A) has duly adopted the
          plan of merger set forth herein and approved this Agreement and the
          other transactions contemplated hereby, (B) has declared that the
          Merger and this Agreement and the other transactions contemplated
          hereby are advisable and in the best interests of the Company and its
          stockholders, and (C) has received the Fairness Opinion.

        (d)  GOVERNMENTAL FILINGS; NO VIOLATIONS.

             (i) Other than the filings and/or notices (A) pursuant to Section
     2.2 or as set forth in Section 4.1(d) of the Company Disclosure Letter,
     (B) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
     amended (the "HSR ACT"), the Exchange Act, the Securities Act of 1933, as
     amended (the "SECURITIES ACT"), the Investment Company Act of 1940 (the
     "1940 ACT"), the Investment Advisers Act of 1940, as amended (the "ADVISERS
     ACT") and the Change in Bank Control Act, as amended (the "BANK CONTROL
     ACT"), (C) to comply with state banking or securities or "blue-sky" laws,
     and (D) required to be made with the NYSE, the National Association of
     Securities Dealers, Inc. ("NASD") and other applicable self-regulatory
     organizations, no filings, reports or notices are required to be made by
     the Company with, nor are any consents, registrations, approvals, permits
     or authorizations required to be obtained by the Company from, any
     governmental or regulatory authority, agency, commission, body or other
     governmental entity ("GOVERNMENTAL ENTITY"), in connection with the
     execution and delivery of this Agreement by the Company and the
     consummation by the Company of the Merger and the other transactions
     contemplated hereby.


                                      -13-
<PAGE>


              (ii)  The execution, delivery and performance of this Agreement by
     the Company do not, and the consummation by the Company of the Merger and
     the other transactions contemplated hereby will not, constitute or result
     in (A) a breach or violation of, or a default under, the charter or bylaws
     of the Company or the comparable governing instruments of any of its
     Subsidiaries, (B) a breach or violation of, or a default under, the
     acceleration of any obligations or the creation of a lien, pledge, security
     interest or other encumbrance on the assets of the Company or any of its
     Subsidiaries (with or without notice, lapse of time or both) pursuant to,
     any agreement, lease, contract, note, mortgage, indenture, arrangement or
     other obligation, whether written or oral ("CONTRACTS" and individually, a
     "CONTRACT"), binding upon the Company or any of its Subsidiaries (provided,
     as to consummation, the filings, reports and notices are made, and
     approvals are obtained, as referred to in Section 4.1(d)(i)) or any
     Applicable Law or governmental or non-governmental permit, registration,
     authorization or license to which the Company or any of its Subsidiaries is
     subject, or (C) any change in the rights or obligations of any party under
     any Contract, except, in the case of clause (B) or (C) above, for any
     breach, violation, default, acceleration, creation or change that is not,
     individually or in the aggregate, reasonably likely to have a Company
     Material Adverse Effect. Section 4.1(d) of the Company Disclosure Letter
     sets forth a correct and complete list of all Material Contracts (as
     defined below) of the Company and its Subsidiaries pursuant to which
     consents or waivers are or may be required prior to consummation of the
     transactions contemplated by this Agreement (whether or not subject to the
     exception set forth with respect to clauses (B) and (C) above).

        (e)  COMPANY REPORTS; FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES.

        (i)  The Company has delivered or made available to Parent each
     registration statement, report, proxy statement or information statement
     prepared by it since December 31, 1997, including the Company's Annual
     Report on Form 10-K for the year ended December 31, 1999 (the "AUDIT DATE,"
     and such report on Form 10-K, the "COMPANY 1999 10-K") in the form
     (including exhibits, annexes and any amendments thereto) filed with the SEC
     (collectively, including any such reports filed with the SEC subsequent to
     the date hereof, the "COMPANY REPORTS"). As of their respective dates, the
     Company Reports did not, and any Company Reports filed with the SEC
     subsequent to the date hereof will not, contain any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements made therein, in light of the
     circumstances in which they were made, not misleading. Each of the
     consolidated balance sheets included in or incorporated by reference into
     the Company Reports (including the related notes and schedules) fairly
     presents, or will fairly present, the consolidated financial position of
     the Company and its Subsidiaries as of its date and each of the
     consolidated statements of income and of cash flows included in or
     incorporated by reference into the Company Reports (including any related
     notes and schedules) fairly presents, or will fairly present, the results
     of operations, retained earnings and changes in financial position, as the
     case may be, of the Company and its Subsidiaries for the periods set forth
     therein (subject, in the case of unaudited statements, to notes and normal
     year-end audit adjustments that will not be material in amount or effect),
     in each case in accordance with accounting principles generally accepted in
     the United States ("U.S.




                                      -14-

     GAAP") consistently applied during the periods involved, except as may be
     noted therein.

              (ii)  Except for those liabilities that are disclosed in the
     Company Reports filed prior to the date hereof, neither the Company nor any
     of its Subsidiaries has incurred any liability of any nature whatsoever
     (whether absolute, accrued, contingent or otherwise and whether due or to
     become due) that, individually or in the aggregate, has had or is
     reasonably likely to have a Company Material Adverse Effect.

        (f)  ABSENCE OF CERTAIN CHANGES. Except as disclosed in the Company
Reports filed prior to the date hereof, since the Audit Date the Company and its
Subsidiaries have conducted their respective businesses only in, and have not
engaged in any material transaction other than according to, the ordinary and
usual course of such businesses consistent with past practice and there has not
been (i) any change in the financial condition, operations, properties, business
or results of operations of the Company and its Subsidiaries or any development
or combination of developments, that, individually or in the aggregate, has had
or is reasonably likely to have a Company Material Adverse Effect; (ii) any
damage, destruction or other casualty loss with respect to any material asset or
property owned, leased or otherwise used by the Company or any of its
Subsidiaries, whether or not covered by insurance, except for such damage,
destruction or other casualty loss which, individually or in the aggregate, has
not had and is not reasonably likely to have a Company Material Adverse Effect;
(iii) any change by the Company in Tax or accounting principles, practices or
methods other than as required by U.S. GAAP or Applicable Law or as disclosed in
the Company Reports filed prior to the date hereof; or (iv) any declaration,
setting aside or payment of any dividend or other distribution in respect of the
stock of the Company, other than regular quarterly cash dividends paid by the
Company not in excess of $0.20 per Common Share. Since the Audit Date, except as
provided for herein or as disclosed in the Company Reports filed prior to the
date hereof, there has not been any increase in the compensation payable or that
would become payable by the Company to officers or key employees of the Company
or any of its Subsidiaries or any amendment of any of the Compensation and
Benefit Plans (as defined in Section 4.1(i)) other than increases or amendments
in the ordinary course consistent with past practice.

         (g)  PROXY STATEMENT; OFFER DOCUMENTS. The Proxy Statement will comply
in all material respects with the Securities Act and the Exchange Act, except
that no representation is made by the Company with respect to information
supplied by Parent for inclusion in the Proxy Statement. None of the information
supplied by the Company in writing for inclusion in the Offer Documents or
provided by the Company in the Schedule 14D-9 will, at the respective times that
the Offer Documents and the Schedule 14D-9 are filed with the SEC and are first
published or sent or given to holders of Common Shares, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

         (h)  LITIGATION AND LIABILITIES. Except as disclosed in the Company
Reports filed prior to the date hereof, there are no (i) civil, criminal or
administrative actions, suits, claims, hearings, investigations, inquiries or
proceedings pending or, to the Knowledge of the Company, threatened against the

abilities of any nature, whether or not accrued, contingent or otherwise and
whether or not required to be disclosed, or any other facts or circumstances of
which the Company has Knowledge that is reasonably likely to result in any
claims against, or obligations or liabilities of, the Company or any of its
Subsidiaries, except for those that are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect.

          (i)   EMPLOYEE BENEFITS.

               (i)   A copy of each material bonus, incentive, deferred
     compensation, pension, retirement, profit-sharing, thrift, savings,
     employee stock ownership, stock bonus, stock purchase, restricted stock,
     stock option, employment, termination, severance, compensation, medical,
     health, welfare, fringe benefits or other plan, or agreement that covers
     employees, directors, former employees or former directors of the Company
     or any of its Subsidiaries with respect to service for the Company or any
     of its Subsidiaries (the "COMPENSATION AND BENEFIT PLANS") and any trust
     agreement or insurance contract forming a part of any such Compensation
     and Benefit Plan has been made available to Parent prior to the date
     hereof. The Compensation and Benefit Plans are listed in Section 4.1(i) of
     the Company Disclosure Letter.

             (ii)  All Compensation and Benefit Plans are in substantial
     compliance with all Applicable Law, including the Code and the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA"), and any
     regulations and rules promulgated thereunder and any applicable foreign
     law. Each Compensation and Benefit Plan that is an "employee pension
     benefit plan" within the meaning of Section 3(2) of ERISA (a "PENSION
     PLAN") and that is intended to be qualified under Section 401(a) of the
     Code has received a favorable determination letter from the Internal
     Revenue Service (the "IRS"), and to the Knowledge of the Company, there are
     no existing circumstances that are reasonably likely to result in
     revocation of any such favorable determination letter. There is no pending
     or, to the Knowledge of the Company, threatened legal action, suit, claim
     or governmental investigation relating to any of the Compensation and
     Benefit Plans, other than claims for benefits in the ordinary course.
     Neither the Company nor any of its Subsidiaries has engaged in a
     transaction with respect to any Compensation and Benefit Plan that,
     assuming the taxable period of such transaction expired as of the date
     hereof, would be reasonably likely to subject the Company or any of its
     Subsidiaries to a material Tax or penalty imposed by either Section 4975 of
     the Code or Section 502 of ERISA.

              (iii)  None of the Compensation and Benefit Plans is subject to
     Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code. None
     of the Company and its Subsidiaries nor any of their respective ERISA
     Affiliates (as defined below) has, at any time during the last six years,
     contributed to or been obligated to contribute to any "multiemployer plan"
     within the meaning of Section 4001(a)(3) of ERISA (a "MULTIEMPLOYER PLAN");
     and (iii) none of the Company and its Subsidiaries nor any ERISA Affiliates
     has incurred any liability to a Multiemployer Plan as a result of a
     complete or partial withdrawal from such Multiemployer Plan, as those terms
     are defined in Part I of Subtitle E of Title IV of ERISA, that has not been
     satisfied in full. "ERISA AFFILIATE" means, with respect to the Company or
     any of its Subsidiaries, any entity, trade or business, that is a member of
     a group described in Section 414(b), (c), (m) or (o) of the Code or Section


                                      -16-
<PAGE>

     4001(b)(1) of ERISA that includes the Company or such Subsidiary, or that
     is a member of the same "controlled group" as the Company or such
     Subsidiary pursuant to Section 4001(a)(14) of ERISA.

              (iv)  All material contributions required to be made under the
     terms of any Compensation and Benefit Plan as of the date hereof have been
     made or have been reflected on the Company's or the appropriate
     Subsidiary's most recent financial statements.

               (v)   Neither the Company nor any of its Subsidiaries have any
     obligations for retiree health and life benefits under any Compensation and
     Benefit Plan, other than benefits mandated under Section 4980B of the Code
     or by other Applicable Law, or pursuant to individual agreements.

              (vi)  The consummation of the Merger and the other transactions
     contemplated by this Agreement (including as a result of any termination of
     employment in connection therewith) will not (A) entitle any employee,
     consultant or director of the Company or any of its Subsidiaries to any
     payment (including severance pay or similar compensation) or any increase
     in compensation, (B) accelerate the time of payment or vesting or trigger
     any payment of compensation or benefits under, increase the amount payable
     or trigger any other material obligation pursuant to, any of the
     Compensation and Benefit Plans, or (C) result in any payment becoming due
     by Parent, Purchaser, the Company or any of its Subsidiaries that would be
     subject to Sections 162(m), 280G or 4999 of the Code.

              (vii)  With respect to each Compensation and Benefit Plan, if
     applicable, the Company has provided, made available, or will make
     available upon request, to Parent, true and complete copies of existing:
     (A) the most recent Form 5500 filed with the IRS; (B) the most recent
     financial statement; (C) the most recent summary plan description; and (D)

     recognition or certification, and there are no representation or
     certification proceedings or petitions seeking a representation proceeding

     involving the Company or any of its Subsidiaries pending with any labor
     organization or group of employees of the Company or any of its

all amendments thereto (together with the Contracts referred to in the first
sentence of this paragraph (p) and any other material Contracts of the Company
and its Subsidiaries, including all revenue sharing contracts, contracts of the
Company to finance or otherwise support the operations of its Subsidiaries or
compensate employees of its Subsidiaries, and all contracts for the acquisition
of Subsidiaries, the "MATERIAL CONTRACTS"). Neither the Company nor any of its
Subsidiaries nor, to the Knowledge of the Company, any other party is in breach
of or in default under any Material Contract except for such breaches and
defaults as are not, individually or in the aggregate, reasonably likely to have
a Company Material Adverse Effect.

        (q)  INVESTMENT CONTRACTS, FUNDS AND CLIENTS.

             (i)  Certain of the Company's Subsidiaries provide investment
     management, investment advisory and sub-advisory and certain other related
     services (each such Subsidiary, an "ADVISORY ENTITY"). Each Contract for
     such services is referred to herein as an "INVESTMENT CONTRACT"; each other
     party thereto or other Person with respect to which an Advisory Entity
     provides investment advice thereunder is referred herein to as a "CLIENT";
     each Client that is registered as an investment company under the 1940 Act
     is referred to herein as a "FUND CLIENT"; and each Client that is an
     investment company but is exempt from registration under the 1940 Act by
     virtue of sections 3(c)(1) and 3(c)(7) of that Act is referred to herein as
     an "EXEMPT FUND CLIENT."

                (A)  Except as is not, individually or in the aggregate,
          reasonably likely to have a Company Material Adverse Effect, there
          does not exist under any Investment Contract any event or condition
          that, after notice or lapse of time or both, would constitute an event
          of default thereunder on the part of the Company or such Subsidiary,
          or, to the Knowledge of the Company, any other party thereto.

                (B)  Except as is not, individually or in the aggregate,
          reasonably likely to have a Company Material Adverse Effect, each
          commodity trading advisor disclosure document provided by the Company
          or any of its Subsidiaries to any Client did not contain any untrue
          statement of a material fact or omit to state a material fact
          necessary in order to make the statements made therein, in light of
          the circumstances under which they were made, not misleading.

                (C)  Except as is not, individually or in the aggregate,
          reasonably likely to have a Company Material Adverse Effect, neither
          the Company, any of its Subsidiaries or, to the Company's Knowledge,
          any other person "associated" with the Company or any of its
          Subsidiaries (as defined under the Advisers Act), has been convicted
          of any crime or has been subject to any disqualification that would be
          a basis for denial, suspension, or revocation of registration of an
          investment adviser under Section 203(e) of the Advisers Act or Rule
          206(4)-4(b) thereunder or of a broker-dealer under Section 15 of the
          Exchange Act during the five-year period immediately preceding the
          date hereof; and, to the Knowledge of Company, there is no basis for,
          or proceeding or investigation that could reasonably be expected to
          become the basis for, any such disqualification, denial, suspension or
          revocation.

          (ii)  FUND CLIENTS.

                (A)  Except in the case of Subadvisory Fund Clients, each Fund
          Client is, and at all times required under the securities laws has
          been, duly registered with the SEC as an investment company under the
          1940 Act; and each Fund Client, except for Subadvisory Fund Clients,
          and except as would not, individually or in the aggregate, reasonably
          be likely to have a Company Material Adverse Effect, is in compliance
          with (1) the Applicable Laws, regulations, rules or orders of the SEC,
          NASD, the IRS, and any other governmental agency or self-regulatory
          body having jurisdiction over such Fund Client or its distributor or
          investment adviser, (2) the Applicable Laws of any state in which such
          Fund Client is registered, qualified, or sold, and (3) the terms and
          conditions of its Prospectus and Statement of Additional Information.

                (B)(1) Except as is not, individually or in the aggregate,
          reasonably likely to have a Company Material Adverse Effect, each
          Investment Contract in effect on the date hereof between the Company
          or any of its Subsidiaries and a Fund Client or any other investment
          company registered under the 1940 Act and any subsequent renewal has
          been duly authorized, executed and delivered by the Company or such
          Subsidiary, as the case may be, the Fund Client and, to the Knowledge
          of the Company, each other party thereto, if any; and is a valid and
          legally binding agreement, enforceable against the Company or such
          Subsidiary, as the case may be, and, to the Knowledge of Company, each
          other party thereto; and (2) each Investment Contract with a Fund
          Client, except in the case of Subadvisory Fund Clients, and except as
          is not, individually or in the aggregate, reasonably likely to have a
          Company Material Adverse Effect, has been adopted in compliance with
          Section 15 of the 1940 Act and, if applicable, Rule 12b-1 thereunder.

          Agreement, shall include any related statement of additional
          information), as amended or supplemented, relating to each Fund Client
          (except Subadvisory Fund Clients), is in substantial compliance with
          the requirements of the Securities Act and the 1940 Act, applicable
          state laws and, where applicable, the rules of the NASD. None of such
          prospectuses, amendments or supplements, as of their respective dates,
          includes or included an untrue statement of a material fact or omits
          or omitted to state a material fact necessary in order to make the
          statements made therein, in the light of the circumstances under which
          they were made, not misleading.

                (D)   Except in the case of Subadvisory Fund Clients, and except
          as is not, individually or in the aggregate, reasonably likely to have
          a Company Material Adverse Effect, none of the Investment Contracts
          between a Fund Client and the Company or any Subsidiary of the Company
          contains any undertaking by such entity to cap fees or to reimburse
          any or all fees thereunder, except as of the date hereof, (i) as may
          be disclosed in the applicable Fund Client Financial Statements or
          (ii) as has been previously disclosed, and except, as of any other
          date on or prior to the Effective Time as may be agreed from time to
          time with the Board of any Fund Client on terms deemed to be in the
          best interests of such Fund Client and its shareholders.

                (E)   Except in the case of Subadvisory Fund Clients, and except
          as is not, individually or in the aggregate, reasonably likely to have

          the Board of a Fund Client under Rule 12b-1 under the 1940 Act ("12B-1
          PLAN") (or form of 12b-1 Plan adopted by similar series or classes of
          shares offered by more than one investment company registered under
          the 1940 Act) and all payments due since January 1, 1998 under each
          distribution or principal underwriting agreement to which any Fund
          Client is a party have been made in compliance with the related 12b-1
          Plan; and the operation of each such 12b-1 Plan currently complies
          with Rule 12b-1.

                (F)   Except in the case of Subadvisory Fund Clients, and
          except as is not, individually or in the aggregate, reasonably likely
          to have a Company Material Adverse Effect, (1) each of the Fund
          Clients has issued its shares, units or other interests and operated
          in substantial compliance with its investment objectives and policies
          and with Applicable Law, including Section 17 of the 1940 Act; and (2)
          each Board of a Fund Client has been established and operates in
          conformity with the requirements and restrictions of Sections 10 and
          16 of the 1940 Act.

                (G)    Each Subsidiary of the Company that acts as an investment
          adviser or distributor to an investment company registered under the
          1940 Act has adopted a formal code of ethics and a written policy
          regarding insider trading, each of which substantially complies with
          Applicable Law. The policies of the Company and each such Subsidiary
          with respect to avoiding conflicts of interest are as set forth in the
          most recent Forms ADV thereof, as amended; and to the Company's
          Knowledge, there have been no material violations or allegations of


                                      -24-
<PAGE>

          violations of such policies that have occurred or been made that have
          not been addressed in accordance with these procedures.

          officers, directors, or employees of the Company or its Subsidiaries
          has any express or implied understanding or arrangement that would
          impose an unfair burden on any of the Fund Clients or would in any way
          violate Section 15(f) of the 1940 Act as a result of this transaction.

                (I)   Neither the Company, any of its Subsidiaries, the Fund
          Clients or, to the best of the Company's Knowledge, any other person
          "associated" (as defined under the Advisers Act) with Company, any of
          its Subsidiaries or any of the Fund Clients, has for a period not less
          than five (5) years prior to the date hereof been convicted of any
          crime, or is or has been subject to any disqualification that would be
          a basis for disqualification as an investment adviser to any
          investment company pursuant to Section 9(a) of the 1940 Act, and, to
          Company's Knowledge, there is no basis for, or proceeding or
          investigation that could become the basis for, any such
          disqualification.

                (J)  Except in the case of Subadvisory Fund Clients, and except

          and (2) each Fund Client is in substantial compliance with the terms
          and conditions of its constituent documents.

                (iii)  EXEMPT FUND CLIENTS.

          exclusion from any representation or warranty in paragraph (m) or (q)
          relating to any Subadvisory Fund Client shall apply only to the extent
          that the Company or any Subsidiary of the Company does not have any
          contractual or other legal responsibility in the event such
          representation or warranty fails to be true or correct.

Except as set forth in the disclosure letter delivered to the Company by Parent
on or prior to entering into this Agreement (the "PARENT DISCLOSURE LETTER"),
Parent hereby represents and warrants to the Company that (it being understood
that the words "to the Knowledge of Parent" or "Parent's Knowledge" and any
words of similar import shall mean the actual knowledge of the persons whose
names are set forth in Section 4.2(a) of the Parent Disclosure Letter):

        (a)  ORGANIZATION, GOOD STANDING AND QUALIFICATION. Each of Parent
and Purchaser is a corporation duly organized, validly existing and (in the case
of Purchaser) in good standing under the laws of its respective jurisdiction of
organization and has all requisite corporate or similar power and authority to
own and operate its properties and assets and to carry on its business as
presently conducted and is qualified to do business and is in good standing as a
foreign corporation in each jurisdiction where the ownership or operation of its
properties or conduct of its business requires such qualification, except where
the failure to be so qualified or in such good standing, when taken together
with all other such failures, is not, individually or in the aggregate,
reasonably likely to have a Parent Material Adverse Effect (as defined below).

        As used in this Agreement, the term "PARENT MATERIAL ADVERSE EFFECT"
means a material adverse effect on the financial condition, operations,
properties, business or results of operations of Parent and its Subsidiaries
taken as a whole (other than any change or effect arising out of (A) a decline
or deterioration in the economy or the capital markets in general or the markets
in which Parent and its Subsidiaries operate, or (B) this Agreement or the
transactions contemplated hereby or the announcement thereof ) or an effect
which is reasonably likely to prevent, materially delay or materially impair the
ability of Parent to consummate the transactions contemplated by this Agreement.

        (b)  PURCHASER. Since the date of its incorporation, Purchaser has
not carried on any business or conducted any operations other than the execution
of this Agreement, the performance of its obligations hereunder and matters
ancillary thereto. Purchaser was incorporated solely for the purpose of
consummating the transactions contemplated hereby. The authorized capital stock
of Purchaser consists of 100 shares of common stock, par value $0.01 per share,
10 shares of which are validly issued and outstanding, fully paid and
nonassessable and are owned by Parent free and clear of all liens, claims and
encumbrances.

         (c)   CORPORATE AUTHORITY; APPROVAL.

               (i)   Each of Parent and Purchaser has all requisite corporate
     power and authority and, subject, if required under Applicable Law (or
     under any requirements of the London Stock Exchange), to approval by the
     holders of a majority of Parent's outstanding ordinary shares, has taken
     all corporate action necessary in order to execute, de-


                                      -27-
<PAGE>

     liver and perform its obligations under this Agreement and to consummate
     the Merger. This Agreement is a valid and binding agreement of each of
     Parent and Purchaser enforceable against each of Parent and Purchaser in
     accordance with its terms, subject to the Bankruptcy and Equity Exception.

               (ii)  (A) The Board of Directors of each of Parent and Purchaser
     has duly adopted the plan of merger set forth herein and approved this
     Agreement and the other transactions contemplated hereby, and (B) the Board
     of Directors of Purchaser has declared that the Merger and this Agreement
     and the other transactions contemplated hereby are advisable and in the
     best interests of Purchaser and its stockholders and adopted the plan of
     merger set forth herein.

          (d)  FINANCING. Parent has available, and will have available as
of the time of acceptance for payment and purchase of the Common Shares pursuant
to the Offer, and will timely provide Purchaser with, all funds necessary to pay
for all Common Shares that the Purchaser becomes obligated to accept for payment
and pay for pursuant to the Offer and to consummate the Merger and the
transactions contemplated by this Agreement.

          (e)   GOVERNMENTAL FILINGS; NO VIOLATIONS.

                (i)  Other than the filings and/or notices (A) pursuant to

     with state banking or securities or "blue sky" laws, and (E) required to be
     made with the NYSE, the NASD, the London Stock Exchange and other
     applicable self-regulatory organizations, no filings, reports or notices
     are required to be made by Parent or Purchaser with, nor are any consents,
     registrations, approvals, permits or authorizations required to be obtained
     by Parent from, any Governmental Entity, in connection with the execution
     and delivery of this Agreement by Parent or Purchaser and the consummation
     by Parent or Purchaser of the Offer, the Merger and the other transactions
     contemplated hereby, except those that the failure to make or obtain are
     not, individually or in the aggregate, reasonably likely to have a Parent
     Material Adverse Effect.

                (ii)  The execution, delivery and performance of this Agreement
     by Parent and Purchaser do not, and the consummation by Parent and
     Purchaser of the Offer, the Merger and the other transactions contemplated
     hereby will not, constitute or result in (A) a breach or violation of, or a
     default under, the charter or bylaws (or comparable governing instruments)
     of Parent or Purchaser, (B) a breach or violation of, or a default under,
     the acceleration of any obligations or the creation of a lien, pledge,

     to, any Contract binding upon Parent or any of its Subsidiaries (provided,
     as to consummation, the filings, reports and notices are made, and
     approvals are obtained, as referred to in Section 4.2(e)(i)) or any
     Applicable Law (or under any requirements of the London Stock Exchange) or

     license to which Parent or any of its Subsidiaries is subject, or (C) any
     change in the rights or obligations of any party under


                                      -28-
<PAGE>

     any Contract, except, in the case of clause (B) or (C) above, for breach,
     violation, default, acceleration, creation or change that is not,
     individually or in the aggregate, reasonably likely to have a Parent
     Material Adverse Effect.

             (f)  PROXY STATEMENT; SCHEDULE 14D-9. None of the information
supplied or to be supplied by Parent or Purchaser in writing for inclusion in
the Proxy Statement, if any, the Schedule 14D-9 or other filings with the SEC
required to effectuate the transactions contemplated by this Agreement will, at
the respective times that the Proxy Statement, if any, the Schedule 14D-9 or
such other filings are filed with the SEC and are first published or sent or
given to holders of Common Shares, and in the case of the Proxy Statement, if
any, at the time that it or any amendment or supplement thereto is mailed to the
Company's stockholders, at the time of the Special Meeting or at the Effective
Time, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

              (g) BROKERS AND FINDERS. Neither Parent nor any of its officers,
directors or employees has employed any broker or finder or incurred any
liability for any brokerage fees, commissions or finders' fees in connection
with the Merger or the other transactions contemplated in this Agreement except
that Parent has employed Credit Suisse First Boston and Chase Securities, Inc.
as its financial advisors.

          (a)  Parent covenants and agrees as to itself and each of its
Subsidiaries that, after the date hereof and prior to the Effective Time (unless
the Company shall otherwise approve in writing) neither it nor any of its
Subsidiaries shall take any action that would cause any representation or
warranty of Parent herein to become untrue in any material respect, and neither
it nor any of its Subsidiaries shall authorize or enter into an agreement that
would reasonably be expected to have such an effect.

          (b)  If required under Applicable Law (or under any requirements of
the London Stock Exchange), Parent shall duly call and give notice of within 30
calendar days of the date hereof and, as promptly as reasonably practicable
thereafter, convene and hold an extraordinary general meeting of its
shareholders (the "EGM") for the purpose of seeking prompt shareholder approval
of this Agreement and the transactions contemplated hereby. Subject to its
fiduciary duties under Applicable Law, the Board of Directors of Parent shall
recommend that Parent's shareholders approve this Agreement and the transactions
contemplated hereby, and shall not withdraw or adversely modify its
recommendation in any material respect.

          Section 5.3.   ACQUISITION PROPOSALS.

          (a)  The Company will not, and will not permit or cause any of its

shall direct its and its Subsidiaries' employees, agents and representatives
(including any advisor, investment banker, attorney or ac-


                                      -31-

countant retained by it or any of its Subsidiaries) ("REPRESENTATIVES") not to,
directly or indirectly, initiate, solicit, encourage (including by way of
furnishing non-public information or assistance) or take any other action to
facilitate any inquiries or the making of any proposal or offer with respect to
an Acquisition Proposal, or engage in any negotiations concerning, or provide
any confidential information or data to, or have any discussions with, any
Person relating to an Acquisition Proposal, whether made before or after the
date of this Agreement, or otherwise facilitate any effort or attempt to make or
implement an Acquisition Proposal; PROVIDED, HOWEVER, that prior to the
acceptance for payment of the Shares pursuant to the Offer, the Company may, and
may authorize and permit its employees, agents and Representatives to, furnish
or cause to be furnished confidential information and may participate in such
negotiations and discussions or take any other action otherwise prohibited by
this Section 5.3(a) with any Person (unless such other action is subject to the
restrictions of Section 5.3(b), in which case such other action shall only be
permitted in accordance with such restrictions) that, after the date hereof,
makes an unsolicited written Acquisition Proposal if and only to the extent that
(A) the Company Board determines in good faith (after having consulted with
outside legal counsel) that such action is necessary in order for its directors
to comply with their fiduciary duties under Applicable Law, (B) prior to taking
such action, the Company (x) provides notice to Parent to the effect that it
intends to take such action and (y) receives from such Person an executed
confidentiality agreement in reasonably customary form and in any event
containing terms at least as stringent as those contained in the Confidentiality
Agreement (as defined below), and (C) the Company promptly advises Parent of the
identity of such Person and the terms and conditions of any such Acquisition
Proposal. The Company will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing. The Company also will promptly
request each Person that has heretofore executed a confidentiality agreement in
connection with its consideration of an Acquisition Proposal to return all
confidential information heretofore furnished to such Person by the Company or
on the Company's behalf. Neither the Company nor any of its Subsidiaries shall
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which it is a party and shall enforce, to the fullest
extent permitted under Applicable Law, the provisions of any such agreement,
including, but not limited to, by obtaining injunctions to prevent any breaches
of such agreements and to enforce specifically the terms and provisions thereof
in any court having jurisdiction. Notwithstanding the foregoing, nothing
contained herein shall prevent the Company from complying with Rule 14e-2
promulgated under the Exchange Act with regard to an Acquisition Proposal.

            "ACQUISITION PROPOSAL" means any bona fide inquiry, offer or
proposal regarding any of the following (other than the transactions
contemplated by this Agreement): (1) any merger, consolidation, share exchange,
recapitalization, liquidation, dissolution, business combination or other
similar transaction involving the Company or any one or more of its Subsidiaries
having, individually or in the aggregate, assets under management in excess of
$10 billion; (ii) any sale, lease exchange, mortgage, pledge, transfer or other
disposition of the stock or assets of the Company or one or more Subsidiaries of
the Company having, individually or in the aggregate, assets under management in
excess of $10 billion; (iii) any tender offer (including a self tender offer) or
exchange offer that, if consummated, would result in any Person or group
beneficially owning more than 20% of the outstanding Common Shares or the filing
of a registration statement under the Securities Act of 1933 in connection with
any such proposed exchange offer; (iv) any acquisition of 20% or more of the
outstanding Common Shares; or (v) any public an-


                                      -32-
<PAGE>


nouncement by the Company or any third party of a proposal, plan or intention to
do any of the foregoing or any agreement to engage in any of the foregoing.

          (b)  Except as expressly permitted by this Section 5.3(b), the Company
Board shall not approve any letter of intent, agreement in principle,
acquisition agreement or similar agreement relating to any Acquisition Proposal.
The Company may, however, terminate this Agreement pursuant to Section
7.2(a)(vi) if (i) the Company Board has received a Superior Acquisition
Proposal, (ii) in light of such Superior Acquisition Proposal the Company Board
has determined in good faith (after having consulted with outside legal counsel)
that it is necessary for the Company Board to terminate this Agreement in order
to comply with its fiduciary obligations under Applicable Law, (iii) the Company
has notified Parent in writing of the terms of the Superior Acquisition Proposal
and the determinations described in clause (ii) above, (iv) at least five
business days following receipt by Parent of the notice referred to in clause
(iii) above, and taking into account any revised proposal made by Parent since
receipt of the notice referred to in clause (iii) above, such Superior
Acquisition Proposal (as the same may have been modified or amended, but
provided that Parent shall have received the requisite notice of any such
modification or amendment) remains a Superior Acquisition Proposal and the
Company Board has again made the determinations referred to in clause (ii) above
(although no additional time period shall be required following such
determinations, unless Parent shall have, following notice of the determinations
referred to in clause (ii) above, proposed to increase the Offer Price, or
otherwise offered to amend the terms of the transaction contemplated hereby to
make them more favorable to the Company and its stockholders, in which case the
Company shall again notify Parent in writing of the determinations described in
clause (ii) above (but provided that the period specified in this clause (iv)
shall be two business days in the event of any subsequent notice with respect to
a Superior Acquisition Proposal)), (v) the Company is in compliance with Section
5.3(a) and 5.3(b), (vi) the Company Board concurrently approves, and the Company
concurrently enters into, a definitive agreement providing for the
implementation of such Superior Acquisition Proposal, and (vii) the Company
concurrently shall have paid the Termination Fee required by Section 7.3(c), in
the manner contemplated thereby. "SUPERIOR ACQUISITION PROPOSAL" means any bona
fide unsolicited written Acquisition Proposal to acquire all or substantially
all of the Common Shares or assets of the Company which the Company Board
determines in its good faith judgment (after consultation with the Company's
independent financial advisor) to be (x) on terms superior in value from a
financial point of view to the holders of Common Shares than the transactions
contemplated by this Agreement, taking into account all the terms and conditions
of such proposal and this Agreement (including any proposal by Parent to amend
the terms of the transactions contemplated by this Agreement) and (y) reasonably
capable of being completed, taking into account all financial, regulatory, legal
and other aspects of such proposal.

          Section 5.4. INFORMATION SUPPLIED. The Company and Parent each agree,
as to itself and its Subsidiaries, that none of the information supplied or to
be supplied by it or its Subsidiaries for inclusion or incorporation by
reference in the Proxy Statement, the Schedule TO, the Schedule 14D-9, Parent's
shareholder circular (if required under Applicable Law) in connection with the
EGM and any amendment or supplement thereto will, at the date of mailing to
stockholders and at the time of any meeting of stockholders of the Company to be
held in connection with the Merger, in either such case contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

          Section 5.5.  FILINGS; OTHER ACTIONS; NOTIFICATION.

          (a)  The Company and Parent shall cooperate with each other and use
(and shall cause their respective Subsidiaries to use) all reasonable best
efforts to, and propose to the Fund Clients that they, take or cause to be taken
all actions, and do or cause to be done all things, necessary, proper or
advisable on their part under this Agreement and Applicable Laws to consummate
and make effective the Merger and the other transactions contemplated by this
Agreement as soon as practicable, including preparing and filing as promptly as
practicable all documentation to effect all necessary notices, reports,
applications and other filings and to obtain as promptly as practicable all
consents, registrations, approvals, permits and authorizations necessary or
advisable to be obtained from any third party and/or any Governmental Entity in
order to consummate the Merger or any of the other transactions contemplated by
this Agreement, and including (i) contesting any legal proceeding challenging
the Merger; and (ii) the execution of any additional instruments necessary to
consummate the transactions contemplated hereby. Subject to Applicable Laws
relating to the exchange of information, Parent and the Company shall have the
right to review in advance, and to the extent practicable each will consult the
other with respect to all the information relating to Parent or the Company, as
the case may be, and any of their respective Subsidiaries, that appear in any
filing made with, or written materials submitted to, any third party and/or any
Governmental Entity in connection with the Merger and the other transactions
contemplated by this Agreement. In exercising the foregoing right, each of the
Company and Parent shall act reasonably and as promptly as practicable. In case
at any time after the Effective Time any further action is necessary to carry
out the purposes of this Agreement, the proper officers and directors of each
party hereto shall take all such necessary action. Parent shall take all such
action as may be necessary so that holders of the Warrants shall be lawfully and
adequately provided for in accordance with the provisions of any agreement or
instrument relating to the Warrants.

          (b) The Company and Parent each shall, upon request by the other,
furnish the other with all information concerning itself, its Subsidiaries,
directors, officers and stockholders and such other matters as may be reasonably
necessary or advisable in connection with the Proxy Statement or any other
statement, filing, notice or application made by or on behalf of Parent, the
Company or any of their respective Subsidiaries to any third party and/or any
Governmental Entity in connection with the Merger and the transactions
contemplated by this Agreement.

          (c) The Company and Parent each shall keep the other apprised of the
status of matters relating to completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notice or other
communications received by Parent or the Company, as the case may be, or any of
its Subsidiaries, from any third party and/or any Governmental Entity with
respect to the Merger and the other transactions contemplated by this Agreement.
The Company and Parent each shall give prompt notice to the other of any change
(i) that, individually or in the aggregate, is or is reasonably likely to result
in a Company Material Adverse Effect or Parent Material Adverse Effect,
respectively, or would constitute a breach of warranty under this Agreement.

          Section 5.6.  ACCESS. Upon reasonable notice, and except as may
otherwise be required by Applicable Law, the Company shall (and shall cause its
Subsidiaries to) afford Parent's officers, directors or Representatives access,
during normal business hours throughout the


                                      -34-
<PAGE>

period prior to the Effective Time, to the Company's and its Subsidiaries'
personnel, properties, books, contracts and records (including any Tax Returns
and work papers of independent auditors) and, during such period, shall (and
shall cause its Subsidiaries to) furnish promptly to the other all information
concerning the Company's and its Subsidiaries' business, properties, personnel,
Fund Clients and Exempt Fund Clients and to such other information as may
reasonably be requested. During such period, it shall furnish promptly to Parent
and, at the request of Parent, to any of its Representatives (i) a copy of each
report, schedule and other document filed by it, its Subsidiaries or any such
Fund Client or Exempt Fund Client pursuant to the requirements of federal or
state securities laws, and (ii) all other financial and operating data and other
information concerning the business, properties, assets and personnel of it, its
Subsidiaries or any Fund Client or Exempt Fund Client as any of its
Representatives may reasonably request. No investigation pursuant to this
Section shall affect or be deemed to modify any representation or warranty made
by the Company and provided, further, that the foregoing shall not require the
Company to permit any inspection, or to disclose any information, that in the
reasonable judgment of the Company would result in the disclosure of any trade
secrets of third parties or violate any of its obligations with respect to
confidentiality if the Company shall have used all reasonable efforts to obtain
the consent of such third party to such inspection or disclosure. All requests
for information made pursuant to this Section shall be directed to an executive
officer of the Company or such Person as may be designated by either of the
Company's officers. All such information shall be governed by the terms of the
Confidentiality Agreement (as defined in Section 8.7).

          Section 5.7.  STOCK EXCHANGE DE-LISTING. The Surviving Corporation
shall use its best efforts to cause the Common Shares to be de-listed from the
NYSE and de-registered under the Exchange Act as soon as practicable following
the Effective Time.

          Section 5.8.  PUBLICITY. The initial press release shall be a joint
press release and thereafter the Company and Parent each shall consult with each
other prior to issuing any press releases or otherwise making public
announcements with respect to the Merger and the other transactions contemplated
by this Agreement and prior to making any filings with any third party and/or
any Governmental Entity (including any applicable securities exchange) with
respect thereto, except as may be required by Applicable Law or by obligations
pursuant to any listing agreement with or rules of any applicable securities
exchange.

          Section 5.9.   BENEFITS.

          (a) OPTIONS.  Prior to the consummation of the Offer, the Company
Board (or, if appropriate, any committee thereof) shall use its reasonable best
efforts (including by adopting appropriate resolutions and seeking all consents
from optionees) so that immediately prior to the Effective Time, except as may
be otherwise agreed by Parent and the holder of any Company Options, all Company
Options (whether vested or unvested) that are then outstanding shall be
cancelled in exchange for a payment by the Company to the holder thereof in
cash, as soon as practicable following the Effective Time, equal to the product
of (i) the total number of Common Shares subject to such Company Option and (ii)
the excess, if any, of the Offer Price over the exercise price per Common Share
subject to such Company Option (the "CASH PAYMENTS") (less any applicable
withholding Taxes). The Company Board shall use its reasonable best efforts to
terminate the Option Plan, the Stand-Alone Option Plans and any other plan,
program or arrangement providing for the issuance or grant of any other interest
in respect of the capital stock


                                      -35-
<PAGE>

of the Company or any subsidiary in each case effective prior to the Effective
Time. The Company and Parent agree that the Cash Payments are the sole payments
that will be made with respect to or in relation to the Company Options.

          (b)  EMPLOYEE BENEFITS.

            (i)   Parent agrees that, during the period commencing at the
     Effective Time and ending on the second anniversary thereof, the
     individuals who are, as of the Effective Time, employees of the Company and
     its Subsidiaries (the "COMPANY Employees") will continue to be provided
     with benefits under employee benefit plans (other than plans involving the
     issuance of Common Shares) that are no less favorable in the aggregate than
     those currently provided by the Company and its Subsidiaries to such
     Company Employees.

           (ii)  For all purposes under the employee benefit plans of Parent
     and its affiliates providing benefits after the Effective Time, each
     Company Employee shall be credited with his or her years of service with
     the Company and its Subsidiaries before the Effective Time, to the same
     extent as such Company Employee was entitled, before the Effective Time, to
     credit for such service under any similar Compensation and Benefit Plans,
     except to the extent such credit would result in a duplication of benefits.
     In addition, and without limiting the generality of the foregoing: (i) each
     Company Employee shall be immediately eligible to participate, without any
     waiting time, in any and all employee benefit plans sponsored by Parent and
     its affiliates for the benefit of Company Employees (such plans,
     collectively, the "NEW PLANS") to the extent coverage under such New Plan
     replaces coverage under a comparable Compensation and Benefit Plan in which
     such Company Employee participated immediately before the Effective Time
     (such plans, collectively, the "OLD PLANS"); and (ii) for purposes of each
     New Plan providing medical, dental, pharmaceutical and/or vision benefits
     to any Company Employee, Parent shall cause all pre-existing condition
     exclusions and actively-at-work requirements of such New Plan to be waived
     for such employee and his or her covered dependents, and Parent shall cause
     any eligible expenses incurred by such employee and his or her covered
     dependents during the portion of the plan year of the Old Plan ending on
     the date such employee's participation in the corresponding New Plan begins
     to be taken into account under such New Plan for purposes of satisfying all
     deductible, coinsurance and maximum out-of-pocket requirements applicable
     to such employee and his or her covered dependents for the applicable plan
     year as if such amounts had been paid in accordance with such New Plan.

           (iii)  Parent shall, and shall cause the Surviving Corporation to,
     honor the Compensation and Benefit Plans in accordance with their terms as
     in effect immediately before the Effective Time; PROVIDED, that nothing
     herein shall prevent Parent from amending or terminating any Compensation
     and Benefit Plan in accordance with their terms and subject to Applicable
     Law; and PROVIDED, FURTHER, that the Compensation and Benefit Plans listed
     in Section 4.1(i) of the Company Disclosure Letter shall not be amended or
     terminated in any manner adverse to the Company Employees before the first
     anniversary of the Effective Time.



                                      -36-
<PAGE>

            (iv)  Prior to the consummation of the Offer, the Company Board (or,
     if appropriate, any committee thereof) shall cause all account balances of
     participants in the United Asset Management Corporation Profit Sharing and
     401(k) Plan (as amended) to be fully vested immediately prior to the
     Effective Time.

           Section 5.10. EXPENSES. Parent shall pay all charges and expenses,
including those of the Paying Agent, in connection with the transactions
contemplated in Article III. Except as otherwise provided in Section 7.3(b),
whether or not the Merger is consummated, all costs and expenses incurred in
connection with this Agreement and the Merger and the other transactions
contemplated by this Agreement shall be paid by the party incurring such
expense, except that expenses incurred in connection with the filing fee for and
the printing and mailing of the Schedule TO and the Proxy Statement shall be
shared equally by Parent and the Company.

          Section 5.11. INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.

          (a)  From and after the Effective Time, Parent agrees that it will,
and will cause the Surviving Corporation to indemnify and hold harmless each
present and former director and officer of the Company (when acting in such
capacity) determined as of the Effective Time (the "INDEMNIFIED PARTIES")
against any and all costs or expenses (including reasonable attorneys' fees),
judgments, fines, losses, claims, damages or liabilities (collectively, "COSTS")
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of matters existing or occurring at or prior to the Effective Time, whether
asserted or claimed prior to, at or after the Effective Time, to the fullest
extent that the Company would have been permitted under Delaware law and its
charter or bylaws in effect on the date hereof to indemnify such Person (and
Parent shall also advance expenses as incurred to the fullest extent permitted
under applicable law).

          (b)  Any Indemnified Party wishing to claim indemnification under
paragraph (a) of this Section 5.11, upon learning of any such claim, action,
suit, proceeding or investigation, shall promptly notify Parent thereof, but the
failure to so notify shall not relieve Parent or the Surviving Corporation of
any liability it may have to such Indemnified Party to the extent such failure
does not prejudice the indemnifying party. In the event of any such claim,
action, suit, proceeding or investigation (whether arising before or after the
Effective Time), (i) Parent or the Surviving Corporation shall have the right to
assume the defense thereof and neither Parent nor the Surviving Corporation
shall be liable to such Indemnified Parties for any legal expenses of other
counsel or any other expenses subsequently incurred by such Indemnified Parties
in connection with the defense thereof, except that if Parent or the Surviving
Corporation elects not to assume such defense or counsel for the Indemnified
Parties advises that there are issues which raise conflicts of interest between
Parent or the Surviving Corporation and the Indemnified Parties, the Indemnified
Parties may retain counsel reasonably satisfactory to Parent, and Parent or the
Surviving Corporation shall pay all reasonable fees and expenses of such counsel
for the Indemnified Parties promptly as statements therefor are received;
PROVIDED, HOWEVER, that Parent shall be obligated pursuant to this paragraph (b)
to pay for only one firm of counsel for all Indemnified Parties in any
jurisdiction unless, under applicable standards of professional conduct, the use
of one counsel for such Indemnified Parties would present such counsel with a
conflict of interest, (ii) the Indemnified Parties will reasonably cooperate in
the defense of any such matter, and (iii) neither Parent nor the Surviving
Corporation shall be liable for any settlement


                                      -37-
<PAGE>

effected without Parent's prior written consent, which Parent will not
unreasonably withhold; and PROVIDED, FURTHER, that neither Parent nor the
Surviving Corporation shall have any obligation hereunder to any Indemnified
Party if and when a court of competent jurisdiction shall ultimately determine,
and such determination shall have become final, that the indemnification of such
Indemnified Party in the manner contemplated hereby is prohibited by Applicable
Law.

          (c)  The Surviving Corporation shall maintain a policy of officers'
and directors' liability insurance for acts and omissions occurring prior to the
Effective Time with coverage in amount and scope at least as favorable as the
Company's existing directors' and officers' liability insurance coverage ("D&O
INSURANCE") for a period of at least six years after the Effective Time so long
as the annual premium therefor is not in excess of 300% of the last annual
premium paid prior to the date hereof (the "CURRENT PREMIUM"); PROVIDED,
HOWEVER, if the existing D&O Insurance expires, is terminated or canceled during
such six-year period, the Surviving Corporation will use all reasonable efforts
to obtain D&O Insurance for the remainder of such period for a premium not in
excess (on an annualized basis) of 300% of the Current Premium.

          (d)  The provisions of this Section are intended to be for the benefit
of, and shall be enforceable by, each of the Indemnified Parties, their heirs
and their representatives.

          Section 5.12. TAKEOVER STATUTE. If any Takeover Statute is or may
become applicable to the Merger or the other transactions contemplated by this
Agreement, each of Parent and the Company and its Board of Directors shall grant
such approvals and take such actions as are necessary so that such transactions
may be consummated as promptly as practicable on the terms contemplated by this
Agreement, and otherwise act to eliminate or minimize the effects of such
statute or regulation on such transactions.

          Section 5.13. COMPLIANCE WITH 1940 ACT SECTION 15; CLIENT CONSENTS.

          (a) Prior to the Effective Time, the Company shall use its reasonable
best efforts to ensure compliance with Section 15(f) of the 1940 Act, so that
the transactions contemplated by this Agreement will be in compliance at the
Effective Time with Section 15(f) of the 1940 Act, including, to assure that at
the time of the Effective Time at least 75% of the Board of Directors or
Trustees of each Fund Client are not "interested persons" (as such term is
defined in the 1940 Act) of the Surviving Corporation or the Company.

          (b) Parent will use its reasonable best efforts to assure compliance
with the conditions of Section 15(f) of the 1940 Act as it applies to the
transactions contemplated by the Agreement. From and after the Effective Time,
Parent shall conduct the business of the Surviving Corporation so as to assure
that, insofar as within the control of Parent:

              (i)   for a period of three years after the Effective Time, at
     least 75% of the members of the Board of Directors or Trustees of each Fund
     Client which continues its existing or a replacement Investment Contract
     with an Advisory Entity that constitutes an investment advisory agreement
     are not (A) "interested persons" of the Surviving Corporation, or (B)
     "interested persons" of the Company; and

              (ii)  there is not imposed on any Fund Client an "unfair burden"
     (within the meaning of Section 15(f) of the 1940 Act) as a result of the
     transactions contemplated by


                                      -38-
<PAGE>

     this Agreement, or any express or implied terms, conditions or
     understandings applicable thereto.

          (c)  Each of Parent and the Company shall use its reasonable best
efforts to obtain, in accordance with the 1940 Act, (i) in the case of each Fund
Client other than Fund Clients for whom an Advisory Entity provides subadvisory
services, the due consideration and due approval by the board of directors of
such Fund Client, or (ii) in the case of each Fund Client for whom an Advisory
Entity provides subadvisory services, approval of the Fund Client's advisor and
the approval of the board of directors of such Fund Client to the extent
required by Applicable Law ("FUND APPROVAL") of a new advisory agreement to be
in effect with the applicable Advisory Entity immediately following acceptance
for payment of Common Shares in the Offer on the same terms as its Investment
Contract in effect on the date hereof (or as of the date of commencement of
operations of such Fund Client, if after the date hereof). To the extent that
due consideration and approval of any such new Investment Contract by such Fund
Client's securityholders is required under the 1940 Act, the Company shall use
its reasonable best efforts to cause such Fund Client to obtain such approval.

        (d)   As soon as reasonably practicable following the date hereof, the
Company shall cause the Advisory Entities to send notices (each, a "NOTICE"),
(A) informing their Clients of the transactions contemplated by this Agreement,
(B) requesting the consent or approval of the assignment or deemed assignment if
client consent to such assignment or deemed assignment is required by Applicable
Law or is required under the respective Investment Contract for such assignment
or deemed assignment resulting from the transactions contemplated hereby, (C)
affirming the Advisory Entity's intention to continue the advisory services
pursuant to the existing Investment Contract following the Effective Time if
such Client does not terminate such Investment Contract prior to the Effective
Time, and (D) stating that the consent of such Client will be deemed to have
been granted if such Client continues to accept such advisory services for at
least 45 days after such Notice without termination, provided that such Client
shall not have affirmatively stated to the Company or such Advisory Entity that
it does not consent or terminated its respective Investment Contract prior to
the acceptance for payment and purchase of the Common Shares pursuant to the
Offer. Before any Notice is sent hereunder, the form of such Notice shall be
provided to Parent for review and approval, which approval shall not be
unreasonably withheld or delayed. Parent agrees that consent for any Investment
Contract to the assignment or deemed assignment resulting from the transactions
contemplated hereby ("CLIENT CONSENT") shall be deemed given for all purposes
hereunder (i) if no consent is required under Applicable Law or the respective
Investment Contract, or (ii) if such consent is required under Applicable Law
(but not under the respective Investment Contract), if the written consent or
approval requested in any Notice is received, or, if the written consent or
approval requested in any Notice is not received within forty-five (45) days of
mailing Notice to a Client (provided that in the event a Client shall, prior to
the Last Month-End, have affirmatively stated in writing to the Company or such
Affiliate of the Company with which such Client has an advisory relationship
that it does not so consent or shall have terminated its respective Investment
Contract, Client Consent shall not be deemed given by such Client) (the
"NEGATIVE CONSENT PROCEDURE"). Parent shall use its reasonable best efforts to
cooperate with and assist the Company in obtaining Client Consents pursuant to
this Section 5.13(d).

          (e)  Notwithstanding anything to the contrary contained herein, the
covenants of the parties contained in this Section 5.13 are intended only for
the benefit of the parties and for no other Person.

          Section 5.14. QUALIFICATION OF THE FUND CLIENTS; FUND CLIENT BOARDS.
Subject to applicable fiduciary duties to the Fund Clients, the Company will use
and cause each of its Subsidiaries to use its reasonable best efforts to ensure
that the Fund Clients take no action (i) that would prevent any Fund Client from
qualifying as a "regulated investment company", within the meaning of Section
851 of the Code, (ii) that would be inconsistent with any Fund Client's
prospectus and other offering, advertising and marketing materials, or (iii)
with respect to the Exempt Fund Clients that are currently taxed as
partnerships, take no action that would cause such an Exempt Fund Client to be
subject to taxation on a net income basis under the Code.

          Section 5.15. EXEMPTION FROM LIABILITY UNDER SECTION 16(B). Parent and
the Company shall take all such steps as may be required or reasonably requested
to cause the transactions contemplated by this Agreement and any other
dispositions of Company equity securities (including derivative securities) in
connection with this Agreement by each individual who is a director or officer
of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act
and the rules and regulations promulgated thereunder, such steps to be taken in
accordance with the No-Action Letter dated January 12, 1999, issued by the SEC
to Skadden, Arps, Slate, Meagher & Flom LLP, or as may otherwise be reasonably
requested by the Company.

          Section 5.16. TRANSFER TAXES. All stock transfer, real estate
transfer, documentary, stamp, recording and other similar Taxes (including
interest, penalties and additions to any such Taxes) ("TRANSFER TAXES") incurred
in connection with the transactions contemplated hereby shall be paid by either
Purchaser or the Surviving Corporation, and the Company shall cooperate with
Purchaser and Parent in preparing, executing and filing any Tax Returns with
respect to, or qualifying for any exemptions from, such Transfer Taxes.

          Section 5.17. INTERIM DIRECTORS. Promptly upon the acceptance for
payment of, and payment by Purchaser for, Common Shares pursuant to the Offer,
Purchaser shall be entitled to designate, for election by the Company Board,
such number of directors on the Company Board as will give Purchaser, subject to
compliance with Section 14(f) of the Exchange Act and the DGCL, majority
representation on the Company Board; PROVIDED, HOWEVER, that in the event that
Purchaser's designees are appointed or elected to the Company Board, until the
Effective Time the Company Board shall have at least three directors who are
directors on the date of this Agreement (the "CONTINUING DIRECTORS"); PROVIDED,
HOWEVER, that, in such event, if the number of Continuing Directors shall be
reduced below three for any reason whatsoever, any remaining Continuing
Directors (or Continuing Director, if there shall be only one remaining) shall
be entitled to designate persons to fill such vacancies who shall be deemed to
be Continuing Directors for purposes of this Agreement or, if no Continuing
Directors then remain, the other directors shall designate three persons to fill
such vacancies who are not officers, shareholders or affiliates of Parent or
Purchaser, and such persons shall be deemed to be Continuing Directors for
purposes of this Agreement. Subject to Applicable Law, the Company shall take
all action requested by Parent necessary to effect any such election, including
mailing to its shareholders the Information Statement containing the information
required by Section 14(f) of the Exchange Act


                                      -40-
<PAGE>

and Rule 14f-1 promulgated thereunder, and the Company shall make such mailing
with the mailing of the Schedule 14D-9 (provided that Purchaser shall have
provided to the Company on a timely basis all information required to be
included in the Information Statement with respect to Purchaser's designees). In
connection with the foregoing, the Company shall promptly, at the option of
Purchaser, either increase the size of the Company Board or obtain the
resignation of such number of its current directors as is necessary to enable
Purchaser's designees to be elected or appointed to the Company Board as
provided above.

            Section 5.18.  AGGREGATE CLIENT REVENUE AS OF MAY 31, 2000. On or
prior to the date that is ten business days following the date hereof, the
Company shall provide to Parent a schedule setting forth Aggregate Client
Revenue as of May 31, 2000. No later than 30 business days before acceptance for
payment of Common Shares in the Offer, Parent may notify the Company of any
disagreement it may have with the information set forth in such schedule and the
reasons for such disagreement. Parent and the Company will work in good faith to
resolve any such disagreement and mutually agree on the amount of Aggregate
Client Revenue as of May 31, 2000 within the following period of ten business
days. If Parent and the Company are unable to so agree, the dispute shall be
submitted to a big five accounting firm, without a substantial relationship with
either Parent or the Company, to be mutually agreed by Parent and the Company,
and, within 15 business days such firm shall determine Aggregate Client Revenue
as of May 31, 2000, which amount as so determined shall be binding on the
parties for all purposes hereunder.

                                      -41-
<PAGE>

in Section 6.1 to be satisfied if such failure was caused by such party's

                                  ARTICLE VII

            (iv)  by action of the Board of Directors of Parent, if, due to an

     warranties or covenants contained in this Agreement,

             (v)  by action of the Company Board, (A) if, due to an occurrence

     of any representation or warranty contained herein ((determined without
     giving effect to any qualifications as to "Parent Material Adverse Effect,"
     "material" or similar qualifications), and excluding those where the
     failure of such representations and warranties to be so true and correct
     (without giving effect to any qualifications as to "Parent Material Adverse
     Effect," "material" or similar qualifications) would not, individually or
     in the aggregate, be reasonably likely to have a Parent Material Adverse
     Effect), which breach cannot be or has not been cured within 20 days after
     the giving of written notice to Parent of such breach; or (y) a material
     breach by Parent or Purchaser of any of its covenants or agreements
     contained herein, which breach cannot be or has not been cured within 20
     days after the giving of written notice to Parent, or

             (vi)   by action of the Company Board, in accordance with all the
     requirements of Section 5.3(b);

      PROVIDED, that the right to terminate this Agreement pursuant to clause
      (i) above shall not be available to any party that has breached in any

      Offer to be consummated prior to the Termination Date, and PROVIDED,
      FURTHER, that this Agreement may not in any event be terminated except
      pursuant to clause (ii) above, at any time after Purchaser shall have

(without giving effect to any qualifications as to "Special Company Material
Adverse Effect," "material" or similar qualifications) at any time on and after
the date hereof and prior to June 30, 2000 as though made on and as of such date
(except to the extent any such representation or warranty expressly speaks as of
an earlier or different date, and except for changes contemplated or permitted
by the terms hereof) except, in either case, where the failure of such
representations and warranties to be so true and correct (without giving effect
to any qualifications as to "Special Company Material Adverse Effect,"
"material" or similar qualifications) would not, in the aggregate, have a
Special Company Material Adverse Effect, and provided that such breach cannot be
or has not been cured within 20 days after the giving of written notice to the
Company of such breach or of an attempted termination pursuant to this Section
7.2(b) (and no such attempted termination shall be effective unless such cure
period shall have expired without the cure of the alleged basis for such
termination).

            For the purposes of this Section 7.2(b), the Company hereby
represents and warrants to Parent that, except as set forth in the Company
Disclosure Letter, the representations and


                                      -43-
<PAGE>

warranties set forth in Section 4.1(a), (b) (as to the final three sentences
only), (d)(ii), (e)(ii), (f), (h), (i), (j), (k), (m), (n), (p), (q) or (s)(ii)
or (iii), are true and correct, MUTATIS MUTANDIS and subject to the other rules
of interpretation set forth in this Section 7.2(b), as if each reference therein
to "the Company" or "the Company and its Subsidiaries" or any similar reference
were instead to "the Special Subsidiaries" (as defined below). For the purposes
of this Section 7.2(b), such representations and warranties shall be called the
"SPECIAL REPRESENTATIONS."

            For the purposes of the Special Representations (x) all references
to Company Material Adverse Effect in the Company Representations shall be
considered to be references to Special Company Material Adverse Effect and (y)
all requirements that any matter be listed, set forth or enumerated on the
Company Disclosure Letter shall be disregarded, and no failure to provide any
otherwise required disclosure shall constitute a breach or violation of the
Special Representations (but all limitations and qualifications set forth in the
Company Disclosure Letter shall be given full effect).

            For the purposes hereof, the following terms shall have the
following meanings:

            "SPECIAL COMPANY MATERIAL ADVERSE EFFECT" means a material adverse
effect on the financial condition, operations, properties, business or results
of operations of the Special Subsidiaries taken as a whole (other than any
change or effect arising out of (A) a decline or deterioration in the economy or
the capital markets in general or the markets in which the Special Subsidiaries
operate, or (B) this Agreement or the transactions contemplated hereby or the
announcement thereof).

            "SPECIAL SUBSIDIARIES" means those Subsidiaries identified as such
in Section 7.2(b) of the Company Disclosure Letter, and "LIMITED SPECIAL
SUBSIDIARIES" means those Subsidiaries identified as such in Section 7.2(b) of
the Company Disclosure Letter.

            If this Agreement is not terminated and the Merger not abandoned in
accordance with this Section 7.2(b), the Special Representations shall cease to
be of any further force or effect, and shall be of no relevance for any purpose
hereunder.

           Section 7.3.  EFFECT OF TERMINATION AND ABANDONMENT.

          (a)  In the event of termination of this Agreement and the abandonment
of the Merger pursuant to this Article VII, this Agreement (other than as set
forth in Section 8.1) shall become void and of no effect with no liability on
the part of any party hereto (or of any of its directors, officers, employees,
agents, legal and financial advisors or other representatives); PROVIDED,
HOWEVER, except as otherwise provided herein, no such termination shall relieve
any party hereto of any liability or damages resulting from any breach of this
Agreement.

          (b)  In the event that this Agreement is terminated by Parent or the
Company pursuant to Section 7.2(a)(i) or by Parent pursuant to Section
7.2(a)(iii) or (iv), and, prior to the date of such termination, any Person
(other than Parent or any Affiliate of Parent) has made to the Company an
Acquisition Proposal or shall have publicly announced an intention (whether or
not conditional) to make a proposal or offer relating to an Acquisition
Proposal, then the Company shall pay to Parent, no later than two business days
after the earlier to occur of (i) the date of entrance by the Company into a
definitive agreement to consummate a transaction that con-


                                      -44-
<PAGE>

stitutes that or any other Acquisition Proposal or (ii) the date any Person
(other than Parent or any Affiliate of Parent) purchases 50% or more of the
assets or voting securities of the Company and its Subsidiaries (provided that
any definitive agreement contemplated by clauses (i) and (ii) of this sentence
is entered into by the Company, or if there is no such agreement with respect to
a purchase contemplated by clause (ii), any tender, exchange or other offer or
arrangement for the Company's voting securities is first publicly disclosed,
within 18 months of such termination of this Agreement), an amount equal to $43
million (the "TERMINATION FEE").

          (c)  This Agreement shall not be terminated by the Company pursuant to
Section 7.2(a)(vi) unless the Company shall concurrently pay to Parent an amount
equal to the Termination Fee by wire transfer of immediately available funds.

          Section 7.4. PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR
WAIVER. A termination of this Agreement pursuant to Section 7.1 or 7.2, an
amendment of this Agreement pursuant to Section 8.2 or an extension or waiver
pursuant to Section 8.3, or any action with similar import or effect shall, in
order to be effective, require in the case of the Company, in the event that
Purchaser's designees are appointed or elected to the Company Board as provided
in Section 5.17, after the acceptance for payment of Common Shares pursuant to
the Offer and prior to the Effective Time, the affirmative vote of the majority
of the Continuing Directors. In the event that Purchaser's designees are
appointed or elected to the Company Board as provided in Section 5.17, after the
acceptance for payment of Common Shares pursuant to the Offer and prior to the
Effective Time, the affirmative vote of the majority of the Continuing Directors
shall be required by the Company to (i) amend or terminate this Agreement, (ii)
exercise or waive any of the Company's rights or remedies under this Agreement,
or (iii) extend the time for performance of Parent's or Purchaser's respective
obligations under this Agreement.

                                     ANNEX I

                             CONDITIONS TO THE OFFER

            Notwithstanding any other provisions of the Offer, Purchaser shall
not be required to accept for payment or (subject to any applicable rules and
regulations of the SEC) pay for, and may delay the acceptance for payment of,
any Common Shares and may terminate or, subject to the terms of the Merger
Agreement, amend the Offer, unless (i) there shall have been validly tendered
and not withdrawn prior to the expiration of the Offer such number of Common
Shares as would constitute, together with any Common Shares theretofore
beneficially owned by Parent, a majority of the outstanding Common Shares
(determined on a fully diluted basis, after giving effect to the exercise or
conversion of all options, rights and securities exercisable or convertible into
voting securities) (the "MINIMUM TENDER CONDITION"), and (ii) the waiting period
applicable to the acceptance for payment and purchase of Common Shares in the
Offer under the HSR Act shall have expired or been terminated, and all reports
or other filings and consents, registrations, approvals, permits or
authorizations in each case that has been specifically identified in the Parent
Disclosure Letter as a condition to Purchaser's obligation to accept for payment
and purchase Common Shares in the Offer (such specifically identified required
notices, reports or other filings and consents, registrations, approvals,
permits and authorizations, collectively, "GOVERNMENTAL CONSENTS"), shall have
been made or obtained (as the case may be), or if, at any time on or after the
date of the Merger Agreement and prior to Purchaser's acceptance for payment of
Common Shares, any of the following conditions exists or shall have occurred and
remain in effect:

          (a) there shall be pending or overtly threatened any action by any
          Governmental Entity, or any Applicable Law enacted, entered, enforced
          or deemed applicable to the Offer, (i) that would reasonably be
          expected to or which does prohibit or impose any material limitations
          on Parent's or Purchaser's ownership or operation (or that of any of
          their respective Subsidiaries or affiliates) of all or a material
          portion of their or the Company's or any of its Subsidiaries'
          businesses or assets, or to compel Parent or Purchaser or their
          respective Subsidiaries and affiliates to dispose of or hold separate
          any material portion of the business or assets of the Company or
          Parent or Purchaser and their respective Subsidiaries, in each case
          taken as a whole, (ii) that would reasonably be expected to or which
          does make the acceptance for payment of, or the payment for, some or
          all of the Common Shares illegal or otherwise prohibiting, restricting
          or significantly delaying acceptance for payment of Common Shares in
          the Offer or consummation of the Merger or the performance of any of
          the other transactions contemplated by the Merger Agreement, or that
          would reasonably be expected to obtain from the Company or Purchaser
          any damages that are material in relation to the Company and its
          Subsidiaries as taken as a whole, (iii) that would reasonably be
          expected to or which does impose material limitations on the ability
          of Purchaser, or render Purchaser unable, to acquire or hold or to
          exercise effectively all material rights of ownership of the Common
          Shares, including, the right to vote any Common Shares purchased by
          Purchaser on all matters properly presented to the stockholders of the
          Company, or effectively to control in any material respect the
          business, assets or operations of the Company, its Subsidiaries or
          Purchaser or any of their respective affiliates, (iv) that would
          reasonably be expected to or which does impose circumstances under

          a Parent Material Adverse Effect, or (v) which otherwise would
          reasonably be expected to have a Company Material Adverse Effect; or

          (b) as of the Last Month-End, there shall not have been (i) Fund
          Approval obtained with respect to Fund Clients and (ii) Client Consent

          accounts, as of such date, together represent 75% (the "REQUIRED
          CONSENT PERCENTAGE") or more of the sum of aggregate Fund Client

          each such account on such date, by the applicable annual fee rate for
          such account at such date (excluding any performance-based fees and
          net of any fee waivers, expense reimbursements or assumptions and
          unreimbursed payments by the Company or such Subsidiaries to brokers,
          dealers or other Persons with respect to the distribution of shares of
          the Fund Clients or services provided to Fund Client shareholders
          pursuant to any distribution or shareholder services agreements). As
          used herein, "NON-FUND CLIENT REVENUE" shall mean, as of any given
          date, the aggregate annualized investment advisory and subadvisory
          fees for all Non-Fund Client accounts managed by the Company and its
          Subsidiaries, determined by multiplying the Adjusted Assets Under
          Management for each such account by the applicable annual fee rate for
          such account at such date (excluding any performance-based fees and
          net of any referral or servicing fees payable by the Company or such
          Subsidiaries). As used herein, the "ADJUSTED ASSETS UNDER MANAGEMENT"
          shall mean, for any account at a particular date, the amount of assets
          under management by the Company or any of its Subsidiaries in that
          account at May 31, 2000, as adjusted for net cash flows (additions,
          withdrawals and reinvestments), new accounts and terminated accounts
          from and after May 31, 2000; or

          (c) as of the Last Month-End, there shall not have been (i) Fund
          Approval obtained with respect to Fund Clients of the Limited Special
          Subsidiaries and (ii) Client Consent obtained, in the manner
          contemplated by Section 5.13(d) of the Merger Agreement, of Non-Fund
          Clients of the Limited Special Subsidiaries, the aggregate Fund Client
          Revenue and Non-Fund Client Revenue of which accounts, as of such
          date, together represent 80% or more of the sum of aggregate Fund
          Client Revenue and Non-Fund Cli-

          ent Revenue as of May 31, 2000 of the Limited Special Subsidiaries; or

          (d) as of the Last Month-End, there shall not have been Fund Approval
          obtained with respect to Fund Clients of Pilgrim, Baxter & Associates,
          the aggregate Fund Client Revenue of which accounts, as of such date,
          together represent 90% or more of the sum of aggregate Fund Client
          Revenue as of May 31, 2000 of Pilgrim, Baxter & Associates; or

          (e) there shall have occurred any changes, events, effects or
          developments that, individually or in the aggregate, constituted, or
          that would reasonably be expected to constitute a Company Material
          Adverse Effect; or

          (f) the Merger Agreement shall have been terminated in accordance with
          its terms; or

          (g) (i) the Company Board shall have withdrawn, changed or modified
          (including by amendment of its Schedule 14D-9), in any such case in a
          manner adverse to Purchaser or Parent, its approval or recommendation
          of the Offer, the Merger Agreement or the Merger or shall have
          recommended an Acquisition Proposal, or shall have adopted any
          resolution to effect any of the foregoing, or (ii) the Company Board
          shall have recommended any proposal other than the Merger Agreement in
          respect of an Acquisition Proposal; PROVIDED, HOWEVER, that any public
          statement by the Company that (A) it has received an Acquisition
          Proposal or otherwise taken any action permitted by Section 5.3(a) of
          the Merger Agreement or (B) otherwise describes the operation of the
          provisions of the Merger Agreement relating to an Acquisition
          Proposal, termination or the Company Board's approval or
          recommendation of the Merger Agreement or the transactions
          contemplated thereby, shall not, in and of themselves, be deemed to be
          a public proposal to withdraw, change or modify the Company Board's
          approval or recommendation for the purposes of this clause (g); or

          (h) the representations and warranties of the Company set forth in the
          Merger Agreement shall not be true and correct (without giving effect
          to any qualifications as to "Company Material Adverse Effect,"
          "material" or similar qualifications) on and as of the Expiration Date
          as though made on and as of the Expiration Date (except to the extent
          any such representation or warranty expressly speaks as of an earlier
          or different date, and except for changes contemplated or permitted by
          the terms hereof) except, in either case, where the failure of such
          representations and warranties to be so true and correct (without
          giving effect to any qualifications as to "Company Material Adverse
          Effect," "material" or similar qualifications) would not, in the
          aggregate, have a Company Material Adverse Effect; or

          (i) the Company shall not have performed in all material respects all
          obligations required to be performed by it under the Merger Agreement
          at or prior to the Expiration Date; or


                                      A-3

          (j) provided such approval is required by Applicable Law (or by any
          requirements of the London Stock Exchange), the Merger Agreement and
          the transactions contemplated hereby shall not have been approved by
          the holders of a majority of Parent's outstanding ordinary shares at
          the EGM; or

          (k) there shall have occurred and be continuing (i) any general
          suspension of trading in, or limitation on prices for, securities on
          the New York Stock Exchange or the London Stock Exchange (excluding
          any coordinated trading halt triggered as a result of a specified
          decrease in a market index) related to market conditions, (ii) a
          declaration of a banking moratorium or any suspension of payments in
          respect of banks in the United States or the United Kingdom by any
          Governmental Entity, (iii) any material mandatory limitation by any
          Governmental Entity on the extension of credit by banks or other
          lending institutions in the United Kingdom, or (iv) a commencement of
          a war directly or indirectly involving the United States or the United
          Kingdom.

            The parties acknowledge that the Tender Offer Conditions set forth
above in this Annex I are for the sole benefit of Parent and Purchaser, that
Parent or Purchaser may assert the failure of any of the Tender Offer Conditions
regardless of the circumstances (other than any circumstance arising solely by
any action or inaction by Parent or Purchaser) giving rise to any such failure,
that the Company shall not assert the failure of, or waive, any such condition
without the prior written consent of Parent and Purchaser, and that if Parent or
Purchaser elects to waive any such condition to the Offer (which Parent or
Purchaser may do in whole or in part at any time and from time to time), the
Company shall cooperate and comply with such election. The failure by Parent or
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right, and each such right shall be deemed an
ongoing right that may be asserted at any time and from time to time.

            Should the Offer be terminated pursuant to any of the foregoing
provisions, all tendered Common Shares not theretofore accepted for payment
shall forthwith be returned to the tendering stockholders.
