ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS.

     On April 21, 1998, Burke Industries, Inc., a California corporation
("Burke"), acquired all of the issued and outstanding capital stock of Mercer
Products Company, Inc., a New Jersey corporation  ("Mercer"), from Sovereign
Specialty Chemicals, Inc., a Delaware corporation ("Sovereign"), for an
aggregate purchase price of $35,750,000, subject to working capital adjustments
(the "Mercer Acquisition") pursuant to a Stock Purchase Agreement, dated
March 5, 1998, among Burke, Sovereign and Mercer (the "Purchase Agreement).

     Financing for the Mercer Acquisition and related expenses was provided, 
in large part, from the sale (the "Offering") of $30 million principal amount 
of Floating Interest Rate Senior Notes Due 2007 (the "Senior Notes") pursuant 
to Rule 144A of the Securities Act of 1933, as amended (the "Securities 
Act").  The balance of the financing was provided with approximately $6.5 
million of cash on hand and $3.0 million from the sale of 3,000 shares of 
Burke's 6% Series C Cumulative Convertible Preferred Stock, on a pro rata 
basis, to the existing shareholders of Burke.

     The Senior Notes mature on August 15, 2007, with interest on the notes
payable semi-annually on February 15 and August 15, commencing August 15, 1998. 
The Senior Notes bear interest at a rate per annum equal to LIBOR plus 400 basis
points, with the interest rate reset semiannually.  The Senior Notes are
unconditionally guaranteed on a joint and several basis by each of Burke's
subsidiaries, including Mercer.  Upon a change of control of Burke, Burke will
be required to make an offer to repurchase all outstanding Senior Notes at 101%
of the aggregate principal amount thereof plus accrued and unpaid interest
thereon at the date of repurchase.

     Burke has agreed to file and use its best efforts to have declared 
effective, under the Securities Act, a registration statement relating to an 
exchange of the unregistered Senior Notes for substantially identical senior 
notes which have been registered under the Securities Act.

     Burke also amended the terms of the indenture relating to its 
outstanding 10% Senior Notes due 2007 (the "Existing Notes") to, among other 
things, permit the issuance of the Senior Notes pursuant to that certain 
First Supplemental Indenture, dated as of April 21, 1998, among Burke, the 
subsidiary guarantors named therein and United States Trust Company of New 
York.

     Founded in 1958, and headquartered in Eustis, Florida, Mercer is a leading
manufacturer of extruded plastic and vinyl products such as vinyl and rubber
cove base, transitional and finish mouldings, corners, stair treads and other
accessories.  Mercer also sells a range of related adhesive products.  Mercer's
product and distribution lines complement Burke's flooring products business. 
While Burke is a dominant producer of rubber cove base and floor covering
accessories in the western United States, Mercer is a leading supplier to the
vinyl cove base and moulding products markets and has a particularly strong
presence in the eastern United States.

The Board of Directors
Mercer Products Company, Inc.:
 
    We have audited the accompanying balance sheet of Mercer Products Company,
Inc. (a wholly owned subsidiary of Laporte plc) as of December 31, 1996, and the
related statements of earnings and retained earnings and cash flows for the year
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Mercer Products Company,
Inc. as of December 31, 1996, and the results of its operations and its cash
flows for the year then ended in conformity with generally accepted accounting

        Inventories are stated at the lower of cost or market, with cost being
    determined on the first-in, first-out basis. Obsolescence is identified
    through quarterly inventory counts and any items appearing on more than two
    consecutive counts are reviewed and, if necessary, prepared for re-grinding.
 
    (c) PROPERTY AND EQUIPMENT
 
        Property and equipment are stated at cost less accumulated depreciation
    and amortization. The Company provides for depreciation and amortization on
    the straight-line method over the estimated useful lives as follows:
 


                                                                 YEARS
                                                                 -----
                                                           
        Building.............................................       50
        Machinery and equipment..............................     7-10
        Furniture and fixtures...............................      3-5
        Leasehold improvements...............................       15

 
    (d) GOODWILL
 
        Goodwill, which represents the excess of purchase price over fair value
    of net assets acquired, is amortized on a straight-line basis over the
    expected periods to be benefited, which is 15 years. Accumulated
    amortization of goodwill and covenants not to compete at December 31, 1996
    was approximately $6,200. The Company assesses the recoverability of this
    intangible asset by determining whether the amortization of the goodwill
    balance over its remaining life can be recovered through undiscounted future
    operating cash flows of the acquired operation. The amount of goodwill
    impairment, if any, is measured based on projected discounted future
    operating cash flows using a discount rate reflecting the Company's average
    cost of funds. The assessment of the recoverability of goodwill will be
    impacted if estimated future operating cash flows are not achieved.
 
    (e) INCOME TAXES
 
        The Company is included within the consolidated Federal income tax
    return of Laporte Inc. in the United States. Income tax expense is
    calculated using the enacted rates in the United States as if the Company
    had been an independent entity.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1996
                                 (IN THOUSANDS)
 
(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

        Deferred tax assets and liabilities are recognized for the future tax
    consequences attributable to differences between the financial statement
    carrying amounts of existing assets and liabilities and their respective tax
    basis and operating loss and tax credit carryforwards. Deferred tax assets
    and liabilities are measured using enacted tax rates expected to apply to
    taxable income in the years in which those temporary differences are
    expected to be recovered or settled. The effect on deferred tax assets and
    liabilities of a change in tax rate is recognized in income in the period
    that includes the enactment date.
 
    (f) USE OF ESTIMATES
 
        The preparation of these financial statements in conformity with
    generally accepted accounting principles required management to make
    estimates and assumptions that affect the reported amounts of assets and
    liabilities and disclosures of contingent assets and liabilities at the date
    of the financial statements and the reported amounts of revenues and
    expenses during the reporting period. Actual results could differ from those
    estimates.
 
    (g) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
        The carrying amounts reported in the Company's balance sheet for cash,
    trade accounts receivable, due from affiliated companies, accounts payable,
    accrued expenses, due to affiliated companies and other liabilities
    approximate their fair value because of the short-term maturity of these
    instruments.
 
        It is not practical to determine the fair value of long-term payable to
    parent and affiliated companies because such amounts, bearing interest
    during the period from January 1, 1996 to December 31, 1996, have no stated
    maturity which makes it difficult to estimate fair value with precision.
 
    (h) CONCENTRATION OF CREDIT RISK
 
        The Company manufactures extruded plastic and vinyl products and markets
    these products to wholesale, specialty, full line, and supply flooring
    distributors and select national and export accounts. As a result, the
    Company grants unsecured credit to customers who deal primarily in the
    industry. Such risk is limited due to the large number of customers,
    generally short payment terms, and their dispersion across geographic areas.
    However, economic factors affecting the industry would have a direct impact
    on the Company and its exposure to credit risk.
 
        One customer accounted for approximately 10% of the Company's sales
    during 1996, and no account receivable from any customer exceeded 10% of the
    Company's accounts receivable balance at December 31, 1996. The Company
    estimates an allowance for doubtful accounts based on the credit worthiness
    of its customers and general economic conditions. Consequently, an adverse
    change in these factors would affect the Company's estimate of bad debts.

                                 (IN THOUSANDS)
 
(5)  RELATED PARTY TRANSACTIONS (CONTINUED)

    (a) PURCHASES OF RAW MATERIALS
 
        Approximately 75% of the raw materials purchased during 1996 were from
    an affiliated company. Management considers that the terms for purchase were
    similar to the terms the Company would have obtained from a third party.
 
    (b) MANAGEMENT FEES
 
        Expenses of $255 that were incurred during the year related to services
    provided by Laporte plc to the Company. These services included general
    management, treasury, tax, financial audit, financial reporting, insurance
    and legal services. The Company has been charged for such services through
    corporate allocations. These expenses were allocated to the Company based on
    estimates of anticipated allocable costs incurred, less amounts charged as
    direct costs or expense rather than by allocation. Management believes that
    the allocation methods used on common expenses were reasonable, produce
    materially accurate results, and are indicative of the expenses that would
    have been incurred had the Company been operated as a stand-alone business.
 
    (c) INTEREST EXPENSE
 
        These financial statements include an allocation of the debt incurred by
    Laporte plc when it originally acquired the Company. Accordingly, interest
    expense at a rate of approximately 9% for 1996 associated with such debt has
    been reflected in these financial statements.
 
    (d) DUE FROM AFFILIATES
 
        Due from affiliates at December 31, 1996 amounts to $93. These
    receivables are noninterest bearing and represent amounts due from other
    subsidiaries of the parent.
 
    (e) DUE TO AFFILIATES
 
        Due to affiliates at December 31, 1996 amounts to $1,219. A total of
    $649 of this balance relates to raw materials purchased from AlphaGary
    Corporation for use in the Company's operations. The remaining balance
    relates to interest payable to the parent for the note outstanding. The
    payables are noninterest bearing.
 
    (f) NOTES PAYABLE TO PARENT
 
        These financial statements include an allocation of the debt incurred by
    Laporte plc when it originally acquired the Company. At December 31, 1996,
    the balance on the loan, net of a receivable from Laporte plc, was $4,655.

    The actual income tax expense for the year ended December 31, 1996 differs
from the expected income tax expense computed by applying the federal statutory
rate of 34% to earnings before income taxes as follows:
 

                                                              
       Expected tax expense....................................  $     427
       Goodwill and other nondeductible items..................        196
       State income taxes, net of federal income tax benefit...         52
                                                                 ---------
                                                                 $     675
                                                                 ---------

    The types of temporary differences between the tax bases of assets and
liabilities and their financial reporting amounts that give rise to the deferred
tax assets and liabilities and their approximate tax effects are as follows:

(7)  EMPLOYEE BENEFIT PLANS
 
    The Company sponsors two defined-contribution plans (an IRS qualifying
401(k) plan and a money purchase pension plan). Participation in these plans is
available to all salaried and hourly employees of the Company. Participating
employees contribute to the 401(k) plan based on a percentage of their
compensation. A percentage of employee contributions are matched by the Company.
The Company further contributes an amount based on a percentage of employee's
pay to the money purchase pension plan. The costs of these plans amounted to
approximately $176 for 1996.

                         NOTES TO FINANCIAL STATEMENTS
                 PERIOD FROM JANUARY 1, 1997 TO AUGUST 4, 1997
                             (DOLLARS IN THOUSANDS)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Mercer Products Company, Inc. (the Company) is a wholly owned subsidiary of
Laporte plc. The Company is primarily a producer of rubber and vinyl products
for sale to wholesale distributors, mainly in the construction, industrial, and
flooring industry. The Company sells domestically to customers throughout the
United States. A significant portion of the Company's sales are to customers in
the construction, industrial, and flooring industry, and as such the company is
affected by the well-being of that industry. The Company does not require
collateral, and all their accounts receivable are unsecured; and while they
believe their trade receivables will be collected, the Company anticipates that
in the event of default they will follow normal collection procedures. Overall,
credit risk related to the Company is limited due to a large number of customers
in differing industries and geographic areas.
 
    Effective August 5, 1997, the Company was purchased by Sovereign Specialty
Chemicals, Inc.
 
INVENTORIES
 
    Inventories are stated at the lower of cost, using the first in, first out
method, or market.
 
PROPERTY, PLANT, AND EQUIPMENT
 
    Property, plant, and equipment are stated at cost.
 
    Depreciation on property, plant, and equipment is calculated on the
straight-line method over the estimated useful lives of the assets. The
following table summarizes the estimated useful lives of the Company's property,
plant, and equipment:
 


                                                                     YEARS
                                                                     -----
                                                               
       Building.................................................          40
       Machinery and equipment..................................          15

 
GOODWILL
 
    Goodwill, which represents the excess of purchase price over fair value of
net assets acquired, is amortized on a straight-line basis over the expected
periods to be benefited, which is 15 years. Accumulated amortization of goodwill
at August 4, 1997, was $6,689. The Company assesses the recoverability of this
intangible asset by determining whether the amortization of the goodwill balance
over its remaining life can be recovered through undiscounted future operating
cash flows of the acquired operation. The amount of goodwill impairment, if any,
is measured based on projected discounted future operating cash flows using a
discount rate reflecting the Company's average cost of funds. The assessment of
the recoverability of goodwill will be impacted if estimated future operating
cash flows are not achieved.
 
INCOME TAXES
 
    The Company is included within the consolidated federal income tax return of
Laporte plc in the United States. For the purposes of these financial statements
income tax expense is calculated, using the enacted rates in the United States
as if the Company had been an independent entity.

                         MERCER PRODUCTS COMPANY, INC.
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                 PERIOD FROM JANUARY 1, 1997 TO AUGUST 4, 1997
                             (DOLLARS IN THOUSANDS)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts reported in the Company's balance sheet for cash, trade
accounts receivable due from affiliated companies, accounts payable, accrued
expenses, due to affiliated companies and other liabilities approximate their
fair value because of the short-term maturity of these instruments.
 
    It is not practical to determine the fair value of long-term payable--parent
and affiliated companies because such amounts, bearing interest during the
period from January 1, 1997 to August 4, 1997, of 9%, have no stated maturity
which makes it difficult to estimate fair value with precision.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of trade accounts which are
from its domestic and international customers. To minimize this risk, ongoing
credit evaluations of customers' financial condition are performed, although
collateral is not required. In addition, the Company maintains an allowance for
potential credit losses.
 
2.  INVENTORIES
 
    The components of inventories at August 4, 1997, are as follows:

           allocations. These expenses were allocated to the Company for
           the period from January 1, 1997 through August 4, 1997, based
           on estimates of anticipated allocable costs incurred, less
           amounts charged as direct costs or expense rather than by
           allocation. Management believes that the allocation methods
           used on common expenses were reasonable, produce materially
           accurate results, and are indicative of the expenses that
           would have been incurred had the Company been operated as a
           stand-alone business.
 
       (c) These financial statements include an allocation of the debt
           incurred by Laporte plc when it originally acquired the
           company. Accordingly, interest expense at a rate of 9% for the
           period from January 1, 1997 to August 4, 1997, associated with
           such debt has been reflected in these financial statements in
           addition to interest on funding balances as shown in Note 1.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                 PERIOD FROM JANUARY 1, 1997 TO AUGUST 4, 1997

7.  EMPLOYEE BENEFIT PLANS
 
    The Company sponsors two defined-contribution plans (an IRS qualified 401(k)
plan and a money purchase pension plan). Participation in these plans is
available to all salaried and hourly employees of the Company. Participating
employees contribute to the 401(k) plan based on a percentage of their
compensation which are matched, based on a percentage of employee contributions
by the Company. The Company further contributes an amount based on a percentage
of employee's pay to the money purchase pension plan. The Company recorded
expense for approximately $358 for the period from January 1, 1997 to August 4,
1997.
 
8.  CONCENTRATIONS OF CREDIT RISK
 
    One customer accounted for 10% of the Company's sales during the period from
January 1, 1997 to August 4, 1997, and no accounts receivable from any customer
exceeded 10% of the Company's gross accounts receivable balance at August 4,
1997. The Company estimates an allowance for doubtful accounts based on the
credit worthiness of its customers as well as general economic conditions.
Consequently, an adverse change in those factors could affect the Company's
estimate of its bad debt.
 
    The Company relies on several vendors to supply raw materials needed for its
products. Although there are a limited number of manufacturers capable of
supplying these needs, the Company believes that other suppliers could provide
for the Company's needs in comparable terms. Abrupt changes in the supply flow
could, however, cause a delay in manufacturing and possible inability to meet
sales commitments on schedule and a possible loss of sales, which would affect
operating results adversely.

                         NOTES TO FINANCIAL STATEMENTS
 
                      PERIOD FROM AUGUST 5, 1997 (DATE OF
                       ACQUISITION) TO DECEMBER 31, 1997
                             (DOLLARS IN THOUSANDS)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Mercer Products Company, Inc. (the Company) is a wholly-owned subsidiary of
Sovereign Specialty Chemicals, Inc. (Sovereign or the Parent Company). Effective
August 5, 1997, Sovereign acquired the Company from Laporte plc (Laporte). The
Company was purchased along with two affiliated companies (affiliated
wholly-owned subsidiaries of Laporte). The total purchase price of the
acquisitions was $133.7 million, including $2 million in acquisition costs. The
purchase price allocated to the Company, based on its estimated fair value was
approximately $35.8 million. The acquisition was accounted for as a purchase.
 
    The Company is primarily a producer of rubber and vinyl products for sale to
wholesale distributors, mainly in the construction, industrial, and flooring
industry. The Company sells domestically to customers throughout the United
States. A significant portion of the Company's sales are to customers in the
construction, industrial, and flooring industry, and as such the company is
affected by the well-being of that industry. The Company does not require
collateral and all their accounts receivable are unsecured; and while they
believe their trade receivables will be collected, the Company anticipates that
in the event of default they will follow normal collection procedures. Overall,
credit risk related to the Company is limited due to a large number of customers
in differing industries and geographic areas.
 
INVENTORIES
 
    Inventories are stated at the lower of cost, using the first in, first out
method, or market.
 
PROPERTY, PLANT, AND EQUIPMENT
 
    Property, plant, and equipment are stated at cost.
 
    Depreciation on property, plant, and equipment is calculated on the
straight-line method over the estimated useful lives of the assets. The
following table summarizes the estimated useful lives of the Company's property,
plant, and equipment:
 


                                                             YEARS
                                                             -----
                                                         
          Building........................................      39
          Machinery and equipment.........................    3-10

 
GOODWILL
 
    Goodwill, which represents the excess of purchase price allocated to the
Company over fair value of net assets acquired, is amortized on a straight-line
basis over the expected periods to be benefited, which is 25 years. Accumulated
amortization of goodwill at December 31, 1997, was $421. The Company assesses
the recoverability of this intangible asset by determining whether the
amortization of the goodwill balance over its remaining life can be recovered
through undiscounted future operating cash flows of the acquired operation. The
amount of goodwill impairment, if any, is measured based on projected discounted
future operating cash flows using a discount rate reflecting the Company's
average cost of funds. The assessment of the recoverability of goodwill will be
impacted if estimated future operating cash flows are not achieved.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
DEFERRED FINANCING COSTS
 
    Deferred financing costs are being amortized using the straight-line method
over the term of the related debt of 7 years. Accumulated amortization was $113,
at December 31, 1997.
 
INCOME TAXES
 
    The Company will be included in the consolidated federal income tax return
of Sovereign Specialty Chemicals, Inc. For the purposes of these financial
statements, income tax expense has been calculated as if the Company had been an
independent entity.
 
    Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts reported in the Company's balance sheet for cash, trade
accounts receivable, due from affiliated companies, accounts payable, accrued
expenses, due to affiliated companies and other liabilities approximate their
fair value because of the short-term maturity of these instruments.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of trade accounts which are
from its domestic and international customers. To minimize this risk, ongoing
credit evaluations of customers' financial condition are performed, although
collateral is not required. In addition, the Company maintains an allowance for
potential credit losses.
 
2.  INVENTORIES
 
    The components of inventories at December 31, 1997, are as follows:

5.  OPERATING LEASES
 
    The Company is a leasee under several noncancelable operating leases for
buildings and machinery and equipment, which expire on various dates through
2004. Rent expense was $103 for the period from August 5, 1997 to December 31,
1997. Future minimum annual lease payments under operating leases are as
follows:

    The current tax benefits are reflected in the balance sheet as due from
affiliated companies as the benefits will be used by the Parent Company in its

    The tax effects of temporary differences that give rise to significant
portions of the deferred tax assets and deferred tax liabilities at December 31,
1997, are presented below:

                                                            ---------

 
7.  LONG-TERM DEBT--PARENT COMPANY
 
    In connection with the purchase of the Company by Sovereign, $30 million in
debt was pushed down to the Company and is reflected as a long-term obligation
to Sovereign. The debt bears interest at 8.25%. In addition, the Company has
recorded $1,955 in deferred financing costs.
 
8.  CORPORATE ALLOCATION OF EXPENSES
 
    Since its acquisition by Sovereign, the Company has operated as a
stand-alone entity. As such, for the period from August 5, 1997 to December 31,
1997, expenses have been paid directly by the Company and no allocation of
Corporate expenses were made by Sovereign. Management believes that the costs
reflected by the Company for the period ended December 31, 1997, are indicative
of the expenses that would have been incurred had the Company been a stand-alone
entity.
 
9.  EMPLOYEE BENEFIT PLANS
 
    The Company sponsors a defined-contribution plan (an IRS qualified 401(k)
plan). Participation in this plan is available to all salaried and hourly
employees of the Company. Participating employees contribute to the 401(k) plan
based on a percentage of their compensation which are matched, based on a
percentage of employee contributions by the Company. The Company recorded
expense for approximately $48 for the period from August 5, 1997 to December 31,
1997.

10.  RISK OF CREDIT CONCENTRATIONS
 
    One customer accounted for 10% of the Company's sales during the period from
August 5, 1997 to December 31, 1997, and no accounts receivable from any
customer exceeded 10% of the Company's gross accounts receivable balance at
December 31, 1997. The Company estimates an allowance for doubtful accounts
based on the credit worthiness of its customers as well as general economic
conditions. Consequently, an adverse change in those factors could affect the
Company's estimate of its bad debts.
 
    The Company relies on several vendors to supply raw materials needed for its
products. Although there are a limited number of manufacturers capable of
supplying these needs, the Company believes that other suppliers could provide
for the Company's needs in comparable terms. Abrupt changes in the supply flow
could, however, cause a delay in manufacturing and possible inability to meet
sales commitments on schedule and a possible loss of sales, which would affect
operating results adversely.
 
11.  SUBSEQUENT EVENT
 
    On March 5, 1998, Sovereign entered into a stock purchase agreement (the
Agreement) for the sale of the Company to Burke Industries, Inc. The purchase
price of the sale as stated in the Agreement is approximately $35.8 million and
includes potential adjustments to the price based upon working capital
measurements. Closing of the sale is anticipated to be prior to April 30, 1998.

(b)  PRO FORMA FINANCIAL INFORMATION

     Combined Pro Forma Financial Statements

     (1)    Unaudited Pro Forma Combined Balance Sheet.

     (2)    Unaudited Pro Forma Combined Statement of Income.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
    The following Unaudited Pro Forma Combined Financial Statements (as 
defined below) of the Company are based on the audited financial statements 
of the Company and Mercer appearing elsewhere in this Current Report on Form 
8-K, or incorporated herein by reference, as adjusted to illustrate the 
estimated effects of the Offering, the related financing transactions, the 
Mercer Acquisition and the prior recapitalization of the Company (the "Prior 
Recapitalization," and, collectively, with the Offering, the related 
financing transactions and the Mercer Acquisition, the "Transactions").  The 
unaudited pro forma adjustments are based upon available information and 
certain assumptions that the Company believes are reasonable. The Unaudited 
Pro Forma Combined Financial Statements and accompanying notes should be read 
in conjunction with the historical financial statements of the Company and 
Mercer and other financial information pertaining to the Company and Mercer 
appearing elsewhere in this Current Report on Form 8-K, or incorporated 
herein by reference.
 
    The Unaudited Pro Forma Combined Financial Statements have been prepared 
to give effect to the Transactions, as if such transactions had occurred on 
January 4, 1997 for the statement of income for the year ended January 2, 
1998 (the "Unaudited Pro Forma Combined Income Statement") and on January 2, 
1998 for the balance sheet (the "Unaudited Pro Forma Combined Balance Sheet," 
which together with the Unaudited Pro Forma Combined Statement of Income 
comprise the "Unaudited Pro Forma Combined Financial Statements"). The pro 
forma adjustments relating to the allocation of the purchase price of Mercer 
represent the Company's preliminary determinations of the purchase accounting 
and other adjustments and are based upon available information and certain 
assumptions the Company considers reasonable under the circumstances. Final 
amounts could differ from those set forth therein. The Mercer Acquisition 
will be treated as a purchase for financial accounting purposes.
 
    The Unaudited Pro Forma Combined Financial Statements do not purport to 
be indicative of what the Company's financial position or results of 
operation would actually have been had the Transactions been completed on 
such date or at the beginning of the periods indicated or to project the 
Company's results of operations for any future date.

    price accounting adjustments and of the fair value of the assets acquired or
    assumed has not yet been made. Accordingly, the purchase accounting
    adjustments made in connection with the development of the unaudited pro
    forma financial information reflect the Company's best estimate based upon
    currently available information. Based upon Mercer's December 31, 1997
    balance sheet, the purchase price allocation would be:

    shares of Convertible Preferred Stock, the use of $6,500 of Burke's cash to
    pay a portion of the Mercer Acquisition consideration and the capitalization
    of $3,000 of deferred financing costs; also reflects the elimination of

    equipment, not contractually acquired or assumed from Sovereign in the

           NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF INCOME
                             (DOLLARS IN THOUSANDS)
 
PRIOR RECAPITALIZATION ADJUSTMENTS
 
    The pro forma financial data for Burke (excluding the Mercer Acquisition)
have been derived from the Company's historical financial statements for the
year ended January 2, 1998 as if the Prior Recapitalization occurred on January
4, 1997. The Prior Recapitalization has been accounted for as a recapitalization
that has no impact on the historical basis of assets and liabilities.

    affiliate of the prior principal shareholders of the Company prior to August
    1997.
 
(2) Includes the elimination of $14,105 representing the Company's cost to
    purchase options issued and outstanding under the Company's stock option
    plan in connection with the Prior Recapitalization. Also reflects the
    elimination of expenses of $1,321 incurred in connection with the Prior
    Recapitalization.
 
(3) Reflects a full year of interest on the Existing Notes net of interest on
    prior debt repaid as follows:

Less historical net interest of existing debt refinanced...........     (5,408)
                                                                     ---------
Incremental interest expense.......................................  $   5,592
                                                                     ---------
                                                                     ---------

 
TRANSACTIONS ADJUSTMENTS
 
    The following adjustments reflect the Transactions, including the Offering,
as applied to the Company's pro forma results and Mercer's actual results as if
the Transactions took place on January 4, 1997.
 
(4) Reflects raw material cost savings of $600 primarily due to the shifting of
    raw material purchases away from Mercer's former affiliate and to lower
    cost, non-affiliated suppliers.
 
(5) Adjustment to cost of sales reflects additional depreciation expense of $179
    while adjustment to selling, general and administrative expenses reflects
    additional amortization expense of $1,070 calculated on a straight line
    basis over 15 years of the excess of purchase price over net assets acquired
    in the Mercer Acquisition, net of Mercer's prior amortization expense.
 
(6) Reflects the elimination of management fees paid to a former controlling
    shareholder of Mercer.
 
(7) Reflects interest on the Senior Notes, net of interest on Mercer's debt not
    assumed:
 

                                                                  
Interest on the Senior Notes.......................................  $   2,850
Amortization of debt issuance costs (9 1/2 years)..................        316
Less historical interest expense on Mercer's debt not assumed......     (1,661)
                                                                     ---------
Incremental interest expense.......................................  $   1,505
                                                                     ---------
                                                                     ---------

 
    Each incremental 25 basis point increase or decrease in the assumed interest
    rate of the Senior Notes would increase or decrease annual interest expense
    on the Senior Notes by $75.
 
(8) Reflects the income tax (benefit) provision arising from the pro forma
    adjustments discussed above based on the Company's pro forma estimated
    effective tax rate of 41.0% for the twelve months ended January 2, 1998.
