Ladies and Gentlemen:

    The undersigned hereby tenders to OM Acquisition Corp., a Delaware
corporation ('PURCHASER') and a wholly-owned subsidiary of Old Mutual plc, a
public limited company incorporated in England and Wales ('PARENT'), the
above-described shares of common stock, par value $0.01 per share (the
'SHARES'), of United Asset Management Corporation, a Delaware corporation (the
'COMPANY'), pursuant to Purchaser's offer to purchase all outstanding Shares at
a price of $25.00 per Share, subject to downward adjustment as provided in the
Offer to Purchase, net to the seller in cash, without interest thereon, upon the
terms and subject to the conditions contained in the Offer to Purchase, dated
July 17, 2000, and in this Letter of Transmittal (which, together with any
amendments or supplements thereto or hereto, collectively constitute the
'OFFER'). The undersigned understands that Purchaser reserves the right to
transfer or assign, in whole at any time, or in part from time to time, to one
or more of its affiliates, the right to purchase all or any portion of the
Shares tendered pursuant to the Offer, but any











such transfer or assignment will not relieve Purchaser of its obligations under
the Offer and will in no way prejudice the rights of tendering stockholders to
receive payment for Shares validly tendered and accepted for payment pursuant to
the Offer. Receipt of the Offer is hereby acknowledged.

    The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of June 16, 2000 (the 'MERGER AGREEMENT'), among Parent, Purchaser and the
Company.

    Upon the terms and subject to the conditions of the Offer (and if the Offer
is extended or amended, the terms of any such extension or amendment), subject
to, and effective upon, acceptance for payment of, and payment for, the Shares
tendered herewith in accordance with the terms of the Offer, the undersigned
hereby sells, assigns and transfers to, or upon the order of, Purchaser all
right, title and interest in and to, and any and all claims in respect of or
arising or having arisen as a result of the undersigned's status as a holder of,
all the Shares that are being tendered hereby (and any and all non-cash
dividends, distributions, rights, other Shares or other securities issued or
issuable in respect thereof on or after June 16, 2000 (collectively,
'DISTRIBUTIONS')), and irrevocably constitutes and appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Shares (and  all Distributions), with full power of substitution (such
power of attorney being deemed to be an irrevocable power coupled with an
interest), to (i) deliver certificates for such Shares (and any and all
Distributions), or transfer ownership of such Shares (and any and all
Distributions) on the account books maintained by the Book-Entry Transfer
Facility, together, in any such case, with all accompanying evidences of
transfer and authenticity, to or upon the order of Purchaser, (ii) present such
Shares (and any and all Distributions) for transfer on the books of the Company
and (iii) receive all benefits and otherwise exercise all rights of beneficial
ownership of such Shares (and any and all Distributions), all in accordance with
the terms of the Offer.

    By executing this Letter of Transmittal, the undersigned hereby irrevocably
appoints each designee of Purchaser as the attorney-in-fact and proxy of the
undersigned, each with full power of substitution, to vote at any annual or
special meeting of the Company's stockholders or any adjournment or postponement
thereof or otherwise in such manner as each such attorney-in-fact and proxy or
his substitute shall in his sole discretion deem proper with respect to, to
execute any written consent concerning any matter as each such attorney-in-fact
and proxy or his substitute shall in his sole discretion deem proper with
respect to, and to otherwise act as each such attorney-in-fact and proxy or his
substitute shall in his sole discretion deem proper with respect to, all of the
Shares (and any and all Distributions) tendered hereby and accepted for payment
by Purchaser. This appointment will be effective if and when, and only to the
extent that, Purchaser accepts such Shares for payment pursuant to the Offer.
This power of attorney and proxy are irrevocable and are granted in
consideration of the acceptance for payment of such Shares in accordance with
the terms of the Offer. Such acceptance for payment shall, without further
action, revoke any prior powers of attorney and proxies granted by the
undersigned at any time with respect to such Shares (and any and all
Distributions), and no subsequent powers of attorney, proxies, consents or
revocations may be given by the undersigned with respect thereto (and, if given,
will not be deemed effective). Purchaser reserves the right to require that, in
order for Shares or other securities to be deemed validly tendered, immediately
upon Purchaser's acceptance for payment of such Shares, Purchaser must be able
to exercise full voting, consent and other rights with respect to such Shares
(and any and all Distributions), including voting at any meeting of the
Company's stockholders.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby and all Distributions, that the undersigned owns the Shares tendered
hereby within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended (the 'EXCHANGE ACT'), that the tender of the
tendered Shares complies with Rule 14e-4 under the Exchange Act, and that when
the same are accepted for payment by Purchaser, Purchaser will acquire good,
marketable and unencumbered title thereto and to all Distributions, free and
clear of all liens, restrictions, charges and encumbrances and the same will not
be subject to any adverse claims. The undersigned will, upon request, execute
and deliver any additional documents deemed by the Depositary or Purchaser to be
necessary or desirable to complete the sale, assignment and transfer of the
Shares tendered hereby and all Distributions. In addition, the undersigned shall
remit and transfer promptly to the Depositary for the account of Purchaser all
Distributions in respect of the Shares tendered hereby, accompanied by
appropriate documentation of transfer, and, pending such remittance and transfer
or appropriate assurance thereof, Purchaser shall be entitled to all rights and
privileges as owner of each such Distribution and may withhold the entire
purchase price of the Shares tendered hereby or deduct from such purchase price
the amount or value of such Distribution as determined by Purchaser in its sole
discretion.











    All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned, and any obligation of the undersigned
hereunder shall be binding upon the heirs, executors, administrators, personal
representatives, trustees in bankruptcy, successors and assigns of the
undersigned. Except as stated in the Offer, this tender is irrevocable.

    The undersigned understands that the valid tender of Shares pursuant to any
one of the procedures described in Section 3 of the Offer to Purchase and in the
Instructions hereto will constitute a binding agreement between the undersigned
and Purchaser upon the terms and subject to the conditions of the Offer (and if
the Offer is extended or amended, the terms or conditions of any such extension
or amendment). Without limiting the foregoing, if the price to be paid in the
Offer is amended in accordance with the terms of the Merger Agreement, the price
to be paid to the undersigned will be the amended price notwithstanding the fact
that a different price is stated in this Letter of Transmittal. The undersigned
recognizes that under certain circumstances described in the Offer to Purchase,
Purchaser may not be required to accept for payment any of the Shares tendered
hereby.

    Unless otherwise indicated herein in the box entitled 'Special Payment
Instructions,' please issue the check for the purchase price of all Shares
purchased and/or return any certificates for Shares not tendered or accepted for
payment in the name(s) of the registered holder(s) appearing above under
'Description of Shares Tendered.' Similarly, unless otherwise indicated under
'Special Delivery Instructions,' please mail the check for the purchase price of
all Shares purchased and/or return any certificates for Shares not tendered or
not accepted for payment (and any accompanying documents, as appropriate) to the
address(es) of the registered holder(s) appearing above under 'Description of
Shares Tendered.' In the event that the boxes entitled 'Special Payment
Instructions' and 'Special Delivery Instructions' are both completed, please
issue the check for the purchase price of all Shares purchased and/or return any
certificates evidencing Shares not tendered or not accepted for payment (and any
accompanying documents, as appropriate) in the name(s) of, and deliver such
check and/or return any such certificates (and any accompanying documents, as
appropriate) to, the person(s) so indicated. Unless otherwise indicated herein
in the box entitled 'Special Payment Instructions,' please credit any Shares
tendered herewith by book-entry transfer that are not accepted for payment by
crediting the account at the Book-Entry Transfer Facility designated above. The
undersigned recognizes that Purchaser has no obligation, pursuant to the
'Special Payment Instructions,' to transfer any Shares from the name of the
registered holder thereof if Purchaser does not accept for payment any of the
Shares so tendered.

Agent's Message in connection with a book-entry delivery of Shares, and any
other documents required by this Letter of Transmittal must be received by the
Depositary at one of its addresses specified on the back cover of the Offer to
Purchase on or prior to the Expiration Date and either Share certificates
representing tendered Shares must be received by the Depositary, or such Shares

must be received by the Depositary, in each case on or prior to the Expiration

    If a stockholder desires to tender Shares pursuant to the Offer and such
stockholder's Share certificates are not immediately available or time will not
permit all required documents to reach the Depositary on or prior to the
Expiration Date, or the procedures for book-entry transfer cannot be complied on
a timely basis, such Shares may nevertheless be tendered if all of the following
guaranteed delivery procedures described herein and in Section 3 of the Offer to
Purchase are duly complied with.

    Pursuant to such guaranteed delivery procedures, (i) such tender is made by
or through an Eligible Institution, (ii) a properly completed and duly executed
Notice of Guaranteed Delivery, substantially in the form made available by
Purchaser, is received by the Depositary, as provided below, on or prior to the
Expiration Date and (iii) the Share certificates (or a Book-Entry Confirmation)
representing all tendered Shares, in proper form for transfer, together with a
properly completed and duly executed Letter of Transmittal (or a facsimile
thereof), with any required signature guarantees (or, in the case of a
book-entry transfer, an Agent's Message) and any other documents required by the
Letter of Transmittal are received by the Depositary, within three New York
Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery.

    The term 'AGENT'S MESSAGE' means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of the
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares which are the subject of the Book-Entry
Confirmation, that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that Purchaser may enforce such agreement
against the participant.

    The signatures on this Letter of Transmittal cover the Shares tendered
hereby.

    THE METHOD OF DELIVERY OF CERTIFICATES REPRESENTING THE SHARES, THIS LETTER
OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE
BOOK-ENTRY TRANSFER FACILITY, IS AT THE ELECTION AND SOLE RISK OF THE TENDERING
STOCKHOLDER. THE SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY
THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY
CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.











    No alternative, conditional or contingent tenders will be accepted, and no
fractional Shares will be purchased. All tendering stockholders, by executing
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of acceptance of their Shares for payment.

    3. INADEQUATE SPACE. If the space provided herein under 'Description of

certificate numbers with respect to such Shares should be listed on a separate
signed schedule attached hereto.

    4. PARTIAL TENDERS. (Not applicable to stockholders who tender by book-entry
transfer). If fewer than all the Shares evidenced by any Share certificate
delivered to the Depositary herewith are to be tendered hereby, fill in the
number of Shares that are to be tendered in the box entitled 'Number of Shares
Tendered.' In any such case, new certificate(s) for the remainder of the Shares
that were evidenced by the old Share certificates, but were not tendered by you,
will be sent to the registered holder, unless otherwise provided in the
appropriate box on this Letter of Transmittal, as soon as practicable after the
Expiration Date or the termination of the Offer. All Shares represented by
certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.

this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the face of the certificate(s) without alteration, enlargement or any change
whatsoever.

    If any of the Shares tendered hereby are held of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.

    If any of the tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.

    If this Letter of Transmittal or any Share certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to Purchaser of the authority of such person so to act must be
submitted.

    If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and transmitted hereby, no endorsements of Share certificates or
separate stock powers are required unless payment or certificates for Shares not
tendered or not accepted for payment are to be issued in the name of a person
other than the registered holder(s). Signatures on any such Share certificates
or stock powers must be guaranteed by an Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares evidenced by certificates listed and
transmitted hereby, the Share certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on the Share certificates. Signature(s) on any
such Share certificates or stock powers must be guaranteed by an Eligible
Institution as described in Instruction 1 hereto.

    6. STOCK TRANSFER TAXES. Except as otherwise provided in this
Instruction 6, Purchaser will pay all stock transfer taxes with respect to the
transfer and sale of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price of any Shares purchased is to be made to,
or if certificates for Shares not tendered or not accepted for payment are to be
registered in the name of, any person other than the registered holder(s), or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder(s) or such other person or
otherwise) payable on account of the transfer to such other person will be
deducted from the purchase price of such Shares purchased unless evidence
satisfactory to Purchaser of the payment of such taxes, or exemption therefrom,
is submitted.

    Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Share certificates evidencing the
Shares tendered hereby.

    7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check for the purchase
price of any Shares accepted for payment is to be issued in the name of, and/or
Share certificates for Shares not accepted for payment or not tendered are to be
issued in the name of and/or returned to, a person other than the signer of this
Letter of Transmittal or if a check is to be sent, and/or such certificates are
to be returned, to a person other than the signer of this Letter of Transmittal,
or to an address other than that shown above, the appropriate boxes on this
Letter of











Transmittal should be completed. Any stockholder(s) delivering Shares by
book-entry transfer may request that Shares not purchased be credited to such
account maintained at the Book-Entry Transfer Facility as such stockholder(s)
may designate in the box entitled 'Special Payment Instructions.' If no such
instructions are given, any such Shares not purchased will be returned by
crediting the account at the Book-Entry Transfer Facility designated above as
the account from which such Shares were delivered.

    8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent at its address and phone number specified at
the end of this Letter of Transmittal.

    9. WAIVER OF CONDITIONS. Subject to the Merger Agreement, Purchaser reserves
the absolute right in its sole discretion to waive, at any time or from time to
time, any of the specified conditions of the Offer, in whole or in part, in the
case of any Shares tendered.

    10. BACKUP WITHHOLDING. UNDER THE FEDERAL INCOME TAX LAWS, THE DEPOSITARY
WILL BE REQUIRED TO WITHHOLD 31% OF THE AMOUNT OF ANY PAYMENTS MADE TO CERTAIN
STOCKHOLDERS PURSUANT TO THE OFFER. TO PREVENT BACKUP FEDERAL INCOME TAX
WITHHOLDING ON PAYMENTS MADE TO CERTAIN STOCKHOLDERS WITH RESPECT TO THE
PURCHASE PRICE OF SHARES PURCHASED PURSUANT TO THE OFFER, EACH SUCH STOCKHOLDER
MUST PROVIDE THE DEPOSITARY WITH HIS CORRECT TAXPAYER IDENTIFICATION NUMBER
('TIN') ON THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL AND
CERTIFY, UNDER PENALTY OF PERJURY, THAT SUCH TIN IS CORRECT AND THAT SUCH
STOCKHOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX WITHHOLDING.

    Backup withholding is not an additional income tax. Rather, the amount of
the backup withholding can be credited against the federal income tax liability
of the person subject to the backup withholding, provided that the required
information is given to the IRS. If backup withholding results in an overpayment
of tax, a refund can be obtained by the stockholder upon filing an income tax
return.

    The stockholder is required to give the Depositary the TIN (i.e., social
security number or employer identification number) of the record owner of the
Shares. If the Shares are held in more than one name or are not in the name of
the actual owner, consult the enclosed 'Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9' for additional guidance on which
number to report.

    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN is
provided to the Depositary. However, such amounts will be refunded to such
stockholder if a TIN is provided to the Depositary within 60 days.

    Certain stockholders (including, among others, most corporations and certain
foreign individuals and entities) are not subject to backup withholding.
Noncorporate foreign stockholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, a copy of which may be
obtained from the Depositary, in order to avoid backup withholding. See the
enclosed 'Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9' for more instructions.

    11. LOST, DESTROYED OR STOLEN SHARE CERTIFICATES. If any certificate(s)
representing Shares has (have) been lost, destroyed or stolen, the stockholder
should promptly notify the Depositary by checking the box immediately preceding
the special payment/special delivery instructions and indicating the number of
Shares lost. The stockholder will then be instructed as to the steps that must
be taken in order to replace the Share certificate(s). This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost, destroyed or stolen Share certificates have been followed. To
expedite replacement, call Equiserve, the transfer agent, at (800) 733-5001.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF) TOGETHER WITH
ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN
AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR TENDERED
SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT
TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE EXPIRATION
DATE, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR
GUARANTEED DELIVERY.











                           IMPORTANT TAX INFORMATION

    Under the federal income tax laws, a stockholder whose tendered Shares are
accepted for payment is generally required to provide the Depositary (as payer)
with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder is an individual, the TIN is his social security number. If a
tendering stockholder is subject to backup withholding, such stockholder must
cross out item (2) of Part 2 (the Certification box) on the Substitute
Form W-9. If the Depositary is not provided with the correct TIN, the
stockholder may be subject to a $50 penalty imposed by the Internal Revenue
Service. In addition, payments that are made to such stockholder with respect to
Shares purchased pursuant to the Offer may be subject to backup withholding.

    Certain stockholders (including, among others, most corporations, and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. In order for a foreign individual to qualify as an
exempt recipient, that stockholder must submit a statement, signed under
penalties of perjury, attesting to that individual's exempt status. Such
statements can be obtained from the Depositary. Exempt stockholders, other than
foreign individuals, should furnish their TIN, write 'Exempt' on the face of the
Substitute Form W-9, and sign, date and return the Substitute Form W-9 to the
Depositary. See the enclosed 'Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9' for additional instructions.

    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
income tax. Rather, the amount of the backup withholding can be credited against
the federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the stockholder upon filing an income tax return.

PURPOSE OF SUBSTITUTE FORM W-9

    To prevent backup withholding of federal income tax on payments made to
certain stockholders with respect to Shares purchased pursuant to the Offer, the
stockholder is required to notify the Depositary of such stockholder's correct
TIN by completing the form contained herein certifying that the TIN provided on
Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN).

WHAT NUMBER TO GIVE THE DEPOSITARY

    The stockholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares. If
the Shares are in more than one name or are not in the name of the actual owner,
consult the enclosed 'Guidelines for Certification of Taxpayer Identification
Number on Substitute Form W-9' for additional guidance on which number to
report. If the tendering stockholder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future, such
stockholder should write 'Applied For' in the space provided for in the TIN in
Part 1, and sign and date the Substitute Form W-9. If 'Applied For' is written
in Part 1 and the Depositary is not provided with a TIN within sixty (60) days,
the Depositary will withhold 31% on all payments of the purchase price until a
TIN is provided to the Depositary.

                                am waiting for a number to be issued for me), and

                                (2) I am not subject to backup withholding because: (a) I am exempt from backup
                                    withholding, or (b) I have not been notified by the Internal Revenue Service (the
                                    'IRS') that I am subject to backup withholding as a result of a failure to report
                                    all interest or dividends, or (c) the IRS has notified me that I am no longer
                                    subject to backup withholding.

                                CERTIFICATION INSTRUCTIONS -- You must cross out item (2) above if you have been
                                notified by the IRS that you are currently subject to backup withholding because of
                                under-reporting interest or dividends on your tax returns. However, if after being
                                notified by the IRS that you are subject to backup withholding, you receive another
                                notification from the IRS that you are no longer subject to backup withholding, do not
                                cross out such item (2). (Also see instructions in the enclosed Guidelines)
