     NOTE: SIGNATURES MUST BE PROVIDED BELOW. PLEASE READ THE ACCOMPANYING
                             INSTRUCTIONS CAREFULLY
 
    The undersigned acknowledges that he or she has received and reviewed the
Prospectus, dated December 5, 1997 (the "Prospectus"), of Burke Industries,
Inc., a Delaware corporation (the "Company"), and this Letter of Transmittal
(the "Letter"), which together constitute the Company's offer (the "Exchange
Offer") to exchange an aggregate principal amount of up to $110 million of its
10% Senior Notes due 2007 (the "New Notes") of the Company for a like principal
amount of the issued and outstanding 10% Senior Notes due 2007 (the "Old Notes")
of the Company from the holders (the "Holders") thereof. Capitalized terms used
but not defined herein have the meanings given to them in the Exchange Offer.
 
    For each Old Note accepted for exchange, the Holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note. No interest will be payable on the Old Notes on the date of the
exchange for the New Notes and Old Notes accepted for exchange will cease to
accrue interest from and after the consummation of the Exchange Offer; therefore
no interest will be paid thereon to the Holders at such time. Each New Note will
bear interest at 10% per annum and will be payable in cash semiannually in
arrears on each February 15 and August 15, commencing on February 15, 1998.
Holders of Old Notes accepted for exchange will be deemed to have waived the
right to receive any other payment of interest on the Old Notes. The Company
reserves the right, at any time or from time to time, to extend the Exchange
Offer at its discretion, in which event the term "Expiration Date" shall mean
the latest time and date to which the Exchange Offer is extended. The Company
shall notify the Holders of the Old Notes of any extension by means of a press
release or other public announcement prior to 9:00 A.M., New York City time, on
the next business day after the previously scheduled Expiration Date.
 
    This Letter is to be completed by a Holder of Old Notes either if
certificates are to be forwarded herewith or if a tender of certificates for Old
Notes, if available, is to be made by book-entry transfer to the account
maintained by the Exchange Agent at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures

set forth in "The Exchange Offer--Procedures for Tendering Old Notes" section of
the Prospectus. Holders of Old Notes whose certificates are not immediately
available, or who are unable to deliver their certificates or confirmation of
the book-entry tender of their Old Notes into the Exchange Agent's account at
the Book-Entry Transfer Facility (a "Book-Entry Confirmation") and all other
documents required by this Letter to the Exchange Agent on or prior to the
Expiration Date, may tender their Old Notes according to the guaranteed delivery
procedures set forth in "The Exchange Offer--Guaranteed Delivery Procedures"
section of the Prospectus. See Instruction 1. Delivery of documents to the
Book-Entry Transfer Facility does not constitute delivery to the Exchange Agent.
 
    The undersigned has completed the appropriate boxes below and signed this
Letter to indicate the action the undersigned desires to take with respect to
the Exchange Offer.
 
    List below the Old Notes to which this Letter relates. If the space provided
below is inadequate, the certificate numbers and principal amount of Old Notes
should be listed on a separate signed schedule affixed hereto.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of Old
Notes indicated above. Subject to, and effective upon, the acceptance for
exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns
and transfers to, or upon the order of, the Company all right, title and
interest in and to such Old Notes as are being tendered hereby.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Old Notes tendered
hereby and that the Company will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim when the same are accepted by the Company. The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent as
its agent and attorney-in-fact with full power of substitution, for purposes of
delivering this Letter and the Old Notes to the Company. The Power of Attorney
granted in this paragraph shall be deemed irrevocable from and after the
Expiration Date and coupled with an interest. The undersigned hereby further
represents that any New Notes acquired in exchange for Old Notes tendered hereby
will have been acquired in the ordinary course of business of the person
receiving such New Notes, whether or not such person is the undersigned, that
neither the Holder of such Old Notes nor any such other person is participating,
intends to participate or has an arrangement or understanding with any person to
participate in the distribution of such New Notes and that neither the Holder of
such Old Notes nor any such other person is an "affiliate," of the Company, as
defined in Rule 405 under the Securities Act of 1933, as amended (the
"Securities Act").
 
    The undersigned also acknowledges that this Exchange Offer is being made in
reliance on an interpretation by the staff of the Securities and Exchange
Commission (the "SEC") set forth in no-action letters to third parties, based on
which the Company believes that the New Notes issued in exchange for the Old
Notes pursuant to the Exchange Offer may be offered for resale, resold and
otherwise transferred by any Holder thereof (other than any such Holder that is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such New Notes are
acquired in the ordinary course of such Holder's business and such Holder has no
arrangement with any person to participate in the distribution of such New
Notes. If the undersigned is not a broker-dealer, the undersigned represents
that it is not engaged in, and does not intend to engage in, a distribution of
New Notes. If the undersigned is a broker-dealer that will receive New Notes for
in exchange for Old Notes, it represents that the Old Notes to be exchanged for
New Notes were acquired by it as a result of market-making activities or other
trading activities, and acknowledges that it will deliver a prospectus in
connection with any resale of such New Notes; however, by so acknowledging and
by delivering a prospectus, the undersigned will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. The undersigned
acknowledges that in reliance on an interpretation by the staff of the SEC, a
broker-dealer may fulfill his prospectus delivery requirements with respect to
the New Notes (other than a resale of an unsold allotment from the original sale
of the Old Notes) with the Prospectus which constitutes part of this Exchange
Offer.
 
    The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer--Withdrawal Rights" section
of the Prospectus.
 
    Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please deliver the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not exchanged)
in the name of the undersigned or, in the case of a book-entry delivery of Old
Notes, please credit the account indicated above maintained at the Book-Entry
Transfer Facility. Similarly, unless otherwise indicated under the box entitled
"Special Delivery Instructions" below, please send the New Notes (and, if
applicable, substitute certificates representing Old Notes for any Old Notes not
exchanged) to the undersigned at the address shown above in the box entitled
"Description of Old Notes."

    FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER OF 10% SENIOR
NOTES DUE 2007 FOR ANY AND ALL OUTSTANDING 10% SENIOR NOTES DUE 2007 OF BURKE
INDUSTRIES, INC.
 
    1.  DELIVERY OF THIS LETTER AND NOTES; GUARANTEED DELIVERY PROCEDURES: This
letter is to be completed by noteholders either if certificates are to be
forwarded herewith or if tenders are to be made pursuant to the procedures for
delivery by book-entry transfer set forth in "The Exchange Offer--Procedures for
Tendering Old Notes" section of the Prospectus. Certificates for all physically
tendered Old Notes, or Book-Entry Confirmation, as the case may be, as well as a
properly completed and duly executed letter (or manually signed facsimile
hereof) and any other documents required by this Letter, must be received by the
Exchange Agent at the address set forth herein on or prior to the Expiration
Date, or the tendering Holder must comply with the guaranteed delivery
procedures set forth below. Old Notes tendered hereby must be in denominations
of principal amount of $1,000 and any integral multiple thereof.
 
    Noteholders whose certificates for Old Notes are not immediately available
or who cannot deliver their certificates and all other required documents to the
Exchange Agent on or prior to the Expiration Date, or who cannot complete the
procedure for book-entry transfer on a timely basis, may tender their Old Notes
pursuant to the guaranteed delivery procedures set forth in "The Exchange
Offer--Guaranteed Delivery Procedures" section of the Prospectus. Pursuant to
such procedures, (i) such tender must be made by or through an Eligible
Institution and a Notice of Guaranteed Delivery must be signed by such Holder,
(ii) on or prior to the Expiration Date, the Exchange Agent must receive from
the Holder and the Eligible Institution a properly completed and duly executed
Notice of Guaranteed Delivery (by facsimile transmission, mail or hand
delivery), substantially in the form provided by the Company, setting forth the
name and address of the Holder of Old Notes, the certificate number or numbers
of the tendered Old Notes, and the principal amount of Old Notes tendered,
stating that the tender is being made thereby and guaranteeing that within four
(4) business days after the date of delivery of the Notice of Guaranteed
Delivery, the tendered Old Notes, a duly executed Letter of Transmittal and any
other required documents will be deposited by the Eligible Institution with the

in proper form for transfer, or Book-Entry Confirmation, as the case may be, and
all other documents required by this Letter, must be received by the Exchange
Agent within four (4) business days after the Expiration Date.
 
    The method of delivery of this Letter, the Old Notes and all other required
documents is at the election and risk of the tendering Holders, but the delivery
will be deemed made only when actually received or confirmed by the Exchange
Agent. If such delivery is by mail, it is recommended that registered mail,
properly insured, with return receipt requested, be used. Instead of delivery by
mail, it is recommended that that the Holder use an overnight or hand delivery
service. In all cases, it is suggested that the mailing be made sufficiently in
advance of the Expiration Date to permit delivery to the Exchange Agent prior to
5:00 p.m., New York City time, on the Expiration Date. See "The Exchange Offer"
section of the Prospectus.
 
    2.  PARTIAL TENDERS (NOT APPLICABLE TO NOTEHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER): If less than all of the Old Notes evidenced by a submitted
certificate are to be tendered, the tendering Holder(s) should fill in the
aggregate principal amount of Old Notes to be tendered in the box above entitled
"Description of Old Notes--Principal Amount of Old Notes Transmitted." Holders
whose Old Notes are not tendered or are tendered but not accepted in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights and preferences and subject to the limitations applicable thereto
under the Indenture. Following consummation of the Exchange Offer, the Holders
will continue to be subject to the existing restrictions upon transfer thereof
and the Company will have no further obligation to such Holders to provide for
the registration under the Securities Act of the Old Notes held by them. ALL OF
THE OLD NOTES DELIVERED TO THE EXCHANGE AGENT WILL BE DEEMED TO HAVE BEEN
TENDERED UNLESS OTHERWISE INDICATED.
 
    3.  SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
SIGNATURES: If this Letter is signed by the registered Holder of the Old Notes
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificates without any change whatsoever.
 
    If any tendered Old Notes are owned of record by two or more joint owners,
all such owners must sign this Letter.
 
    If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this Letter as there are different registrations of certificates.
 
    When this Letter is signed by the registered Holder or Holders of the Old
Notes specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If, however, the New Notes are to be issued,
or any untendered Old Notes are to be reissued, to a person other than the
registered Holder, then

endorsements of any certificates transmitted hereby or separate bond powers are
required. Signatures on such certificate(s) must be guaranteed by an Eligible
Institution.
 
    If this Letter is signed by a person other than the registered Holder or
Holders of any certificate(s) specified herein, such certificate(s) must be
endorsed or accompanied by appropriate bond powers, in either case signed
exactly as the name or names of the registered Holder or Holders appear(s) on
the certificate(s) and signatures on such certificate(s) must be guaranteed by
an Eligible Institution.
 
    If this Letter or any certificates or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must be
submitted.
 
    ENDORSEMENTS ON CERTIFICATES FOR OLD NOTES OR SIGNATURES ON BOND POWERS
REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS A MEMBER OF
A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE NATIONAL
ASSOCIATION OF SECURITIES DEALERS, INC. OR BY A COMMERCIAL BANK OR TRUST COMPANY
HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES (AN "ELIGIBLE
INSTITUTION").
 
    SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE INSTITUTION,
PROVIDED THE OLD NOTES ARE TENDERED: (I) BY A REGISTERED HOLDER OF OLD NOTES
(WHICH TERM, FOR PURPOSES OF THE EXCHANGE OFFER, INCLUDES ANY PARTICIPANT IN THE
BOOK-ENTRY TRANSFER FACILITY SYSTEM WHOSE NAME APPEARS ON A SECURITY POSITION
LISTING AS THE HOLDER OF SUCH OLD NOTES) TENDERED WHO HAS NOT COMPLETED THE BOX
ENTITLED "SPECIAL ISSUANCE INSTRUCTIONS" OR "SPECIAL DELIVERY INSTRUCTIONS," ON
THIS LETTER, OR (II) FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION.
 
    4.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS: Tendering Holders of Old
Notes should indicate in the applicable box the name and address to which New
Notes issued pursuant to the Exchange Offer and/or Old Notes not exchanged are
to be sent, if different from the name or address of the person signing this
Letter. In the case of issuance in a different name, the employer identification
or social security number of the person named must also be indicated.
Noteholders tendering Old Notes by book-entry transfer may request that Old
Notes not exchanged be credited to such account maintained at the Book-Entry
Transfer Facility as such noteholder may designate hereon. If no such
instructions are given, such Old Notes not exchanged will be returned to the
name or address of the person signing this Letter.
 
    5.  TRANSFER TAXES: The Company will pay all transfer taxes, if any,
applicable to the transfer of Old Notes to it or its order pursuant to the
Exchange Offer. If however, certificates representing New Notes and/or Old Notes
for principal amounts not tendered or accepted for exchange are to be delivered
to, or are to be registered or issued in the name of, any person other than the
registered Holder of the Old Notes tendered hereby, or if tendered Old Notes are
registered in the name of any person other than the person signing this Letter,
or if a transfer tax is imposed for any reason other than the transfer of Old
Notes to the Company or its order pursuant to the Exchange Offer, the amount of
any such transfer taxes (whether imposed on the registered Holder or any other
persons) will be payable by the tendering Holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted herewith, the
amount of such transfer taxes will be billed directly to such tendering Holder.
 
    EXCEPT AS PROVIDED IN THIS INSTRUCTION 5, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE OLD NOTES SPECIFIED IN THIS LETTER.
 
    6.  WAIVER OF CONDITIONS: The Company reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.
 
    7.  NO CONDITIONAL TENDERS: No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering Holders of Old Notes, by
execution of this Letter, shall waive any right to receive notice of the
acceptance of their Old Notes for exchange.
 
    Neither the Company, the Exchange Agent nor any other person is obligated to
give notice of any defect or irregularity with respect to any tender of Old
Notes nor shall any of them incur any liability for failure to give any such
notice.
 
    8.  MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES: Any Holder whose Old
Notes have been mutilated, lost, stolen or destroyed should contact the Exchange
Agent at the address indicated above for further instructions.

Prospectus and this Letter, may be directed to the Exchange Agent, at the
address indicated above.

                           IMPORTANT TAX INFORMATION
 
    Under current Federal income tax law, any Holder whose tendered Old Notes
are accepted for payment generally is required to provide the Exchange Agent (as
agent for the payer) with his or her correct taxpayer identification number
("TIN") on Substitute Form W-9 below. If such Holder of Old Notes is an
individual, the TIN is his or her social security number. If the Exchange Agent
is not provided with the correct TIN, the Holder of Old Notes may be subject to
a $50 penalty imposed by the Internal Revenue Service. In addition, payments
that are made to such Holders of Old Notes with respect to New Notes may be
subject to backup withholding.
 
    Certain Holders of Old Notes (including, among others, all corporations and
certain foreign individuals) may not be subject to these backup withholding and
reporting requirements. Exempt Holders of Old Notes should indicate their exempt
status on Substitute Form W-9. In order for a foreign individual to qualify as
an exempt recipient, that Holder of Old Notes must submit a properly completed
Internal Revenue Service Form W-8, signed under penalties of perjury, attesting
to his or her exempt status. Such statements can be obtained from the Exchange
Agent. See the enclosed Guidelines for Certification of Taxpayer Identification
Number on Substitute W-9 for additional instructions.
 
    If backup withholding applies, the Exchange Agent is required to withhold 31
percent of any such payments made to the Holder of Old Notes. Backup withholding
is not an additional tax. Rather, the federal income tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained.
 
    PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a Holder of Old
Notes with respect to Old Notes exchanged pursuant to the Exchange Offer, each
Holder of Old Notes is required to notify the Exchange Agent of his, her or its
correct TIN by completing the Substitute Form W-9 below certifying the TIN
provided on such form is correct (or that such Holder of Old Notes is awaiting a
TIN) and that (1) such Holder of Old Notes has not been notified by the Internal
Revenue Service that he, she or it is subject to backup withholding as a result
of failure to report all interest or dividends or (2) the Internal Revenue
Service has notified such Holder of Old Notes that he, she or it is no longer
subject to backup withholding.
 
    WHAT NUMBER TO GIVE THE EXCHANGE AGENT
 
    The Holder of Old Notes is required to give the Exchange Agent the social
security number or employer identification number of the record owner of the Old
Notes. If the Old Notes 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 guidelines on which
number to report.
