Exhibit 99.4


                            STOCK PURCHASE AGREEMENT

                  STOCK PURCHASE AGREEMENT, dated as of February 28, 1998 (the
"Agreement"), among JAVA ACQUISITION CORP., a Delaware corporation (the
"Purchaser"), and each person or entity named in Schedule A to this Agreement
(the "Sellers").

                  WHEREAS, the Purchaser, Sunbeam Corporation, a Delaware
corporation of which the Purchaser is a wholly owned subsidiary ("Parent"), and
Signature Brands USA, Inc., a Delaware corporation (the "Company"), are entering
into an Agreement and Plan of Merger (the "Merger Agreement") simultaneously
with the entry into this Agreement, which provides, among other things, that the
Purchaser, upon the terms and subject to the conditions thereof, make a cash
tender offer (the "Offer") for all issued and outstanding shares of common
stock, par value $.01 per share, of the Company (the "Shares") at a price of
$8.25 per share, and following consummation of the Offer the Purchaser will
merge with and into the Company with the Company as the surviving corporation
(the "Merger") and each then outstanding Share (other than Shares held by (i)
the Parent or any of its wholly owned subsidiaries, (ii) the Company or any of
its wholly owned subsidiaries or (iii) any holder who perfects dissenters'
rights under Delaware law) would be converted

                                        1






into the right to receive $8.25 in cash, or any higher price paid per Share in
the Offer; and

                  WHEREAS, each of the Sellers wishes to sell to the Purchaser,
and the Purchaser wishes to purchase from each of the Sellers, upon the terms
and subject to the conditions hereinafter set forth, the number of Shares (the
"Seller's Shares") set forth in Schedule A hereto opposite the name of each of
the Sellers.

                  NOW, THEREFORE, the parties hereto agree as follows:

                  1. Sellers' Representations. Each of the Sellers severally
represents and warrants to the Purchaser (a) that such Seller has the power and
authority (or the capacity if an individual) to execute and deliver this
Agreement, (b) that, if a corporation, partnership or other entity, this
Agreement has been duly authorized by all requisite action on the part of the
Seller, (c) that the Seller has duly executed and delivered this Agreement and
this Agreement is a valid and binding agreement, enforceable against such Seller
in accordance with its terms, (d) that neither the execution of this Agreement
nor the consummation by such Seller of the transactions contemplated hereby will
constitute a violation of, or conflict with, or default under, any contract,
commitment, agreement, understanding, arrangement or restriction of any kind to
which such Seller is a party or by which such Seller is bound and, if the Seller

is a corporation, partnership or other entity, the organizational documents
thereof, (e) that on the date hereof such Seller has, and at any

                                        2




Closing (as defined below) hereunder such Seller will have (without exception),
good and valid title to such Seller's Shares, free and clear of all claims,
liens, charges, encumbrances and security interests, restricting such Seller's
ability to enter into this Agreement or perform its obligations hereunder, (f)
that there are no options or rights to purchase or acquire, or agreements
relating to any such rights with respect to, any of such Seller's Shares except
pursuant to this Agreement, (g) that the transfer of such Seller's Shares to the
Purchaser hereunder will vest in the Purchaser good and valid title to such
Shares, free and clear of all claims, liens, charges, encumbrances, security
interests or restrictions on voting and (h) that the number of Shares set forth
in Schedule A hereto opposite the name of such Seller constitutes all of the
Shares owned beneficially or of record by such Seller (other than, in the case
of the Sellers listed on Schedule A other than ML-Lee Acquisition Fund, L.P.,
Thomas H. Lee Equity Partners, L.P. and State Street Bank and Trust Company, not
individually but as trustee of the 1989 Thomas H. Lee Nominee Trust
(collectively, the "Major Sellers"), for differences therefrom which are not
material).

                  2. Purchaser's Representations. The Purchaser represents and
warrants to each of the Sellers that (a) the Purchaser has duly authorized,
executed and delivered this Agreement and this Agreement is a valid and binding
agreement, enforceable against the Purchaser in accordance with its terms and
(b) the Purchaser will acquire the Shares for its own account and not with a
view to or for sale in

                                        3




connection with any distribution thereof, and the Purchaser will not sell or
otherwise dispose of the Shares except in compliance with, or pursuant to an
exemption from registration under, the Securities Act of 1933, as amended, and
the rules and regulations thereunder.

                  3. Agreement to Sell. At the Closing provided for in Section 4
of this Agreement and subject to the conditions in Section 5 of this Agreement,
each of the Sellers will sell, transfer and deliver such Seller's Shares to the
Purchaser (duly endorsed for transfer in blank or accompanied by stock transfer
powers duly executed in blank, with all necessary stock transfer tax stamps
affixed and cancelled) and the Purchaser will purchase such Seller's Shares and
deliver to such Seller a certified or official bank check or checks payable to
or upon the order of such Seller in immediately available funds, at a price per
Share equal to $8.25 such higher per Share price as the Purchaser may have paid
pursuant to the Offer. Each Seller will, upon request of the Purchaser, promptly
execute and deliver all additional documents reasonably deemed by the Purchaser

to be necessary, appropriate or desirable to effect, complete and evidence the
sale, assignment and transfer of such Seller's Shares pursuant to this
Agreement.

                  4. Closing. The closing (the "Closing") of the purchase and
sale hereunder shall take place at the office of Skadden, Arps, Slate, Meagher &
Flom LLP, 919 Third Avenue, New York, New York 10022, or such other place as the

                                        4





parties may mutually agree, on the earlier to occur of (i) the first business
day after the purchase of Shares by the Purchaser pursuant to the Offer or (ii)
if the Offer has otherwise terminated or expired, such date (which shall be at
least one business day following the date of notice) as the Purchaser may
specify in writing to the Sellers. Payment for the Shares shall be in
immediately available funds. Any Seller may tender such Seller's Shares pursuant
to the Offer, provided, however, that until such time as such Shares are
accepted for payment pursuant to the Offer, such Shares shall continue to be
governed by this Agreement. If a Seller's Shares are tendered and accepted for
payment pursuant to the Offer, the payment for such Seller's Shares pursuant to
the Offer shall constitute the Closing of the purchase and sale of such Shares
hereunder.

                  5. Conditions to Closing. (a) The obligations of the 
Purchaser and each of the Sellers under this Agreement shall be subject to the
satisfaction at the Closing of each of the following conditions:

                                    (i)  Neither the Purchaser nor such Seller
         shall be subject to any order, decree or injunction of a court of
         competent jurisdiction which prevents or delays the consummation of the
         transactions contemplated by this Agreement and such Closing shall not
         be prohibited by any rule, regulation, ruling or law.

                                        5






                                    (ii) The applicable waiting period with
         respect to such Closing under the Hart-Scott-Rodino Antitrust 
         Improvements Act of 1976, as amended (the "HSR Act"), shall have 
         expired or been terminated.

                                    (iii) The representations and warranties of
         such Seller (in the case of the Purchaser) or the Purchaser (in the
         case of each Seller) shall be true and correct in all material respects
         and such Seller (in the case of the Purchaser) or the Purchaser (in the
         case of each Seller) shall have complied in all material respects with

         its covenants hereunder.

                  6. Changes in Shares. In the event of any change in the number
of Shares outstanding by recapitalization, declaration of a stock split or
combination or payment of a stock dividend or the like, the number of Shares to
be transferred to the Purchaser and the per Share payments to be made to the
Sellers shall be appropriately adjusted. Each Seller's Shares shall include all
Shares acquired after the date hereof by such Seller and all dividends or
distributions in respect of the Seller's Shares.

                  7. Seller's Covenants. Except as provided for herein, each
Seller agrees not to:

                                        6





                           (a) sell, transfer, pledge, assign or otherwise
dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, assignment or other
disposition of such Seller's Shares;

                           (b) grant any proxies, deposit of such Seller's
Shares into a voting trust or enter into a voting agreement with respect to any
of such Shares;

                           (c) solicit, encourage, participate in or initiate
discussions or negotiations with, or provide information to, any person, other
than Parent or any affiliate of Parent, concerning any merger, sale of assets,
sale of shares of capital stock or similar transactions involving the Company
or any subsidiary or division of the Company; provided nothing herein shall be
deemed to limit or restrict in any respect the ability of Directors of the
Company who are Sellers or may be affiliated with Sellers from exercising the
fiduciary duties in accordance with Section 7.6 of the Merger Agreement; or

                           (d) take any action which would make any 
representation or warranty of such Seller herein untrue or incorrect.

                  8. Seller's Actions. Each Major Seller hereby agrees that at
any meeting of the stockholders of the Company however called, it shall (a) vote
such Seller's Shares in favor of the Merger or any other transaction
contemplated by the Merger Agreement, (b) vote such Seller's Shares against any
action or agreement that would result in a breach in any material respect of any
covenant, representation or

                                        7





warranty or any other obligation of the Company under the Merger Agreement and

(c) vote such Seller's Shares against any action or agreement that would impede,
interfere with or discourage the Offer or the Merger, including, but not limited
to: (i) any extraordinary corporate transaction, such as a merger,
reorganization or liquidation involving the Company or any of its subsidiaries,
(ii) a sale or transfer of a material amount of assets of the Company or any of
its subsidiaries, (iii) any change in the management or Board of Directors of
the Company (other than as contemplated by the Merger Agreement), (iv) any
change in the present capitalization or dividend policy of the Company or (v)
any other material change in the Company's corporate structure or business. Each
Major Seller hereby grants the Purchaser as irrevocable proxy and irrevocably
appoints the Purchaser or its designees, with full power of substitution, its
attorney and proxy to vote all such Seller's Shares in respect of any of the
matters set forth in clauses (a) through (c) of this Section and in the manner
specified in such clauses, provided, however, that such proxy shall not apply to
the matters set forth in clause (c)(iii) of this Section until any waiting
period applicable thereto under the HSR Act shall have expired or been
terminated. Such Seller acknowledges and agrees that this proxy is coupled with
an interest, constitutes, among other things, an inducement for Parent and the
Purchaser to enter into the Merger Agreement, is irrevocable and shall not be
terminated by operation of law or otherwise upon the occurrence of any event
(other than the termination of this

                                        8





Agreement) and that no subsequent proxies will be given (and if given will not
be effective). Any such proxy shall terminate upon the termination of this
Agreement.

                  9. Legend. As soon as practicable after the execution of this
Agreement, each Seller shall surrender the certificates representing such
Seller's Shares to the Purchaser so that the following legend may be placed on
such certificates:

                  "The shares of capital stock represented by this certificate
         are subject to a Stock Purchase Agreement, dated as of February 28,
         1998, between [the Purchaser] and [the Seller]."

                  10. Specific Enforcement. The parties hereto acknowledge that
damages would be an inadequate remedy for a breach of this Agreement and that
the obligations of the parties hereto shall be specifically enforceable, in
addition to any other remedy which may be available at law or in equity.

                  11. Brokerage Fees. Each Seller and the Purchaser, in
connection with the transaction contemplated herein, severally and not jointly
agrees to indem nify and hold the other harmless from and against any and all
claims, liabilities or obligations with respect to any brokerage fees,
commissions or finders' fees asserted by any person on the basis of any act or
statement alleged to have been made by such party or its affiliate (other than,
in the case of the Sellers, an affiliate which is also a Seller).


                                        9



                  12. Expenses. Each party hereto shall pay its own expenses
incurred in connection with this Agreement.

                  13. Survival. Notwithstanding anything contained in Section
14(g) hereof to the contrary, none of the representations, warranties and
agreements made by each of the Sellers and by the Purchaser in this Agreement
shall survive the Closing hereunder and any investigation at any time made by or
on behalf of any party hereto.

                  14. Miscellaneous.

                           (a) Amendment, Etc.  This Agreement may not be
modified, altered or supplemented except upon the execution and delivery of a
written agreement executed by the parties hereto.

                           (b) Assignment. No party to this Agreement may assign
any of its rights or obligations under this Agreement without the prior consent
of the other parties except that the rights and obligations of the Purchaser may
be assigned by the Purchaser to Parent or any of its other wholly owned
subsidiaries but no such transfer shall relieve the Purchaser of its obligations
hereunder if such transferee does not perform such obligations.

                           (c) Binding Effect. This Agreement will be binding
upon, inure to the benefit of and be enforceable by each Seller and such
Seller's respective heirs, beneficiaries, executors, representatives and
permitted assigns.
