ELECTION FORM

I.  CONVERTIBLE PREFERRED STOCK OFFERING MEMORANDUM

     I acknowledge receipt of a copy of the Memorandum from David E.
Worthington, dated April 1, 1998 (the "Memorandum"), on behalf of Burke
Industries, Inc. (the "Company").  All terms used below which are defined in the
Memorandum have the same meanings below.

II.  SUBSCRIPTION

     Subject to the terms and conditions hereof, I hereby offer and agree to
purchase the number of shares of Convertible Preferred Stock of the Company
issuable upon the investment of the amount set forth above my signature below.
I acknowledge that if I elect not to purchase my maximum PRO RATA share of the
Convertible Preferred Stock in the Preferred Stock Offering, JFLEI will purchase
such remaining unsubscribed shares of the Convertible Preferred Stock.

     I agree that this Election Form is irrevocable.  If the Preferred Stock
Offering is, however, cancelled or withdrawn for any reason, the Company shall
return to me the funds tendered with this Election Form (with any allocable
interest).  This Election Form may be accepted only by written acknowledgment by
the Company as set forth below and no sale of Convertible Preferred Stock shall
be deemed to have been made hereunder prior to such written acceptance.

III.  REPRESENTATIONS AND WARRANTIES

     I understand that the shares of the Convertible Preferred Stock have not
been registered under the federal Securities Act of 1933, as amended (the
"Securities Act") or registered or qualified under the securities or blue sky
laws of any state and are being offered and sold in reliance upon an exemption
from federal registration provided in Section 4(2) of the Securities Act (and
Regulation D promulgated thereunder) and similar exemptions under state
securities or blue sky laws.  I hereby make the following agreements,
representations, declarations, acknowledgments and warranties with the intent
that they may be relied upon in determining the availability of such exemptions
and my suitability as a purchaser of the Convertible Preferred Stock.

     (1)  I am an "accredited investor" (as such term is defined in Rule 501 of
Regulation D promulgated under the Securities Act) by reason of one of the
following:

          (a)  The undersigned is a bank as defined in Section 3(a)(2) of the
               Securities Act or any savings and loan association or other
               institution as defined in Section 3(a)(5)(A) of the Securities
               Act acting in its individual or fiduciary capacity;

          (b)  The undersigned is a trust with total assets in excess of
               $5,000,000, not formed for the specific purpose of acquiring the
               Convertible Preferred Stock;

          (c)  I am a director or executive officer of the Company;

          (d)  I have an individual net worth, or a joint net worth with my
               spouse, in excess of $1,000,000;

          (e)  I had an individual income in each of 1996 and 1997 in excess of
               $200,000 and reasonably anticipate that I will have income in
               excess of $200,000 in 1998;

          (f)  I had a joint income with my spouse in excess of $300,000 in each
               of 1996 and 1997 and reasonably anticipate reaching the same
               joint income level with my spouse in 1998;

          (g)  The undersigned is a broker or dealer registered pursuant to
               Section 15 of the Securities Exchange Act of 1934, as amended;

               Section 2(13) of the Securities Act;

          (i)  The undersigned is an investment company registered under the
               Investment Company Act of 1940 or a business development company
               as defined in Section 2(a)(48) of the Securities Act; or

          (j)  The undersigned is an entity (including a corporation or
               partnership) in which all of the equity owners individually are
               accredited investors as described above.

All information which I have provided or will provide to the Company, including
but not limited to my and, if applicable, my spouse's financial position and
knowledge of financial and business matters, is true, correct and complete.  I
will promptly provide to the Company written notice


                                          1


of any material changes in my financial position or, if applicable, that of my
spouse that could affect my status as an "accredited investor," and such
information will be true, correct and complete.  I understand that the Company
will rely in a material degree upon the representations contained herein.

    (2)  I am a bona fide resident and domiciliary of the state included in the
address set forth after my signature.  (If the undersigned is a corporation,

enforceable against me in accordance with its terms.

capable of evaluating the merits and risks of an investment in the Convertible
Preferred Stock.  I have not relied in connection with this investment upon any
representations, warranties or agreements other than those set forth in this
Election Form or the Memorandum.  My financial situation is such that I can
afford to bear the economic risk of holding the Convertible Preferred Stock for
an indefinite period of time, and I can afford to suffer the complete loss of my
investment in the Convertible Preferred Stock.

    (5)  I am subscribing for the shares of Convertible Preferred Stock for my
own account and not with a view to or for sale in connection with any
distribution of all or any part of the shares of the Convertible Preferred
Stock.  I have no contract, undertaking, agreement or arrangement with any
person to sell, transfer or pledge to such person or any other person any or all
of the shares of Convertible Preferred Stock for which I am subscribing, and I
have no present plans or intentions to enter into any such contract,
undertaking, agreement or arrangement.  I will acquire title to the shares of
the Convertible Preferred Stock as set forth in my own name.

    (6)  None of the Company or any officer, employee, agent or affiliate of the
Company has made any representations or warranties or statements to me, other
than as are set forth in the Memorandum.

    (7)  I am not relying on the Company with respect to any tax considerations
involved in an investment in the Convertible Preferred Stock.

    (8)  I understand that certain legends as required by applicable federal and
state securities laws will be placed on any certificate or certificates
representing the shares of Convertible Preferred Stock.

    (9)  I understand that neither the federal Securities and Exchange
Commission nor the securities administrator of any state has passed upon the
adequacy or accuracy of the information set forth in the Memorandum or made any
finding or determination as to the fairness of the investment in the shares of
Convertible Preferred Stock or any recommendation or endorsement of the shares
of the Convertible Preferred Stock as an investment.  No contrary representation
has been made to the undersigned.

    (10) At the Company's request, I will promptly furnish such additional
information and execute such other instruments or documents as may reasonably be
required by the Company in connection with my purchase of the Convertible
Preferred Stock.
