                                  (UNAUDITED)

1. MERGER ACTIVITIES:

     Sterling Chemicals, Inc. (prior to the Merger, "Sterling") and STX
Acquisition Corp. ("STX Acquisition"), a Delaware corporation formed in April
1996 by an investor group led by The Sterling Group, Inc. ("TSG") and The
Unicorn Group L.L.C. ("Unicorn"), entered into an Amended and Restated Agreement
and Plan of Merger dated April 24, 1996 (the "Merger Agreement"). On August 20,
1996, the Merger Agreement was approved by a majority of the shares outstanding,
and on August 21, 1996, STX Acquisition merged with and into Sterling, changing
its name to Sterling Chemicals Holdings, Inc. ("Holdings"), and continuing as
the surviving corporation (the "Merger"). In connection with the Merger,
Holdings transferred all of its operating assets and liabilities excluding its
13 1/2% Senior Secured Discount Notes Due 2008 (the "13 1/2% Notes") to a wholly
owned subsidiary, STX Chemicals Corp., which at the time of the Merger changed
its name to Sterling Chemicals, Inc. (after the Merger, "Chemicals"). Holdings
has no direct subsidiaries other than Chemicals. As used herein, the term
"Company" refers to Sterling and its subsidiaries prior to the consummation of
the Merger and, following the Merger, to Holdings and its subsidiaries,
including Chemicals.

     Each share of Sterling's common stock outstanding immediately prior to the
Merger was converted (at the election of the holder thereof) into either $12.00
cash or the right to retain such shares ("Rollover Shares"), with the aggregate
number of Rollover Shares limited to 5.0 million. As a result of the Merger, on
August 21, 1996, the former STX Acquisition stockholders held approximately 5.3
million shares (49%), stockholders with Rollover Shares held approximately 5.0
million shares (46%), and the Company's newly formed Employee Stock Ownership
Plan (the "ESOP") held approximately 542,000 shares (5%) of the outstanding
shares of Holdings' common stock, par value $0.01 per share ("Holdings Common
Stock").

     The Merger was financed by the proceeds of bank term loans of $356.5
million, including an ESOP term loan of $6.5 million, amounts drawn against a
revolving credit facility of $6.4 million each pursuant to a new credit
agreement (the "Original Credit Agreement"), an offering by Chemicals of $275.0
million of Chemicals' 11 3/4% Senior Subordinated Notes Due 2006 (the "11 3/4%
Notes"), an offering of $191.8 million (initial proceeds of $100 million)
representing 191,751 Units, with each unit consisting of one 13 1/2% Note and
one Warrant to purchase three shares of Holdings Common Stock for $0.01 per
share beginning in August 1997, equity raised by STX Acquisition of
approximately $70.7 million, and cash on hand of $10.3 million. These proceeds
were used to redeem Sterling's common stock other than Rollover Shares ($608.3
million), purchase other equity interests (primarily stock appreciation rights
("SARs")) ($14.6 million), repay debt outstanding prior to the Merger ($142.7
million), loan monies to the new ESOP ($6.5 million), and pay fees and expenses
($46.8 million).

     The Company has accounted for the Merger and related financing
(collectively the "1996 Recapitalization") as a series of debt and equity
transactions representing a recapitalization. Accordingly, the historical basis
of the Company's assets and liabilities have not been impacted by the 1996
Recapitalization.


2. BASIS OF PRESENTATION:

     In the opinion of management, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments necessary to present
fairly the consolidated financial position of the Company and Chemicals as of
June 30, 1997 and their consolidated results of operations and cash flows for
the applicable three month and nine month periods ended June 30, 1997 and 1996.
All such adjustments are of a normal and recurring nature. The results of
operations for the periods presented are not necessarily indicative of the
results to be expected for the full year. The accompanying unaudited condensed
consolidated financial statements should be, and are assumed to have been, read
in conjunction with the consolidated financial statements and notes included in
Holdings' and Chemicals' combined Annual Report on Form 10-K for the fiscal year
ended September 30, 1996 (the "Annual Report"). The condensed consolidated
balance sheets as of September 30, 1996 included herein have been derived from
the audited consolidated balance sheets as of September 30, 1996 included in the
Annual Report. The condensed consolidated 

                                       11
<PAGE>
 
financial statements as of and for the three month and nine month periods ended
June 30, 1997 included herein have been subjected to a review by Deloitte &
Touche LLP, the Company's independent public accountants, whose reports are
included herein.

     Certain amounts reported in the financial statements for the prior periods
have been reclassified to conform with the current financial statement
presentation with no effect on net income or stockholders' equity.

</TABLE>

     As part of the 1996 Recapitalization, Chemicals entered into the Original
Credit Agreement with Texas Commerce Bank National Association, as agent bank
for a syndicate of lenders, and Credit Suisse First Boston and Chase Securities,
Inc. as co-arrangers. Funding under the Original Credit Agreement occurred
August 21, 1996, upon the consummation of the Merger. The Original Credit
Agreement provides for facilities consisting of a six and one-half year
revolving credit facility providing for up to $100 million (subject to a monthly
borrowing base calculation) in revolving loans (the "Revolver"), a term loan
facility consisting of a six and one-half year $200 million Tranche A term loan
and an eight-year $150 million Tranche B term loan (the "Original Term Loans"),
and a four-year $6.5 million ESOP Term Loan (the "ESOP Loan").

     On January 31, 1997, the Company acquired (the "AFB Acquisition") the
acrylic fibers business (the "AFB") of Cytec Industries Inc. ("Cytec") (See Note
7). In connection with the AFB Acquisition, Chemicals entered into a credit
agreement (the "New Credit Agreement" and together with the Original Credit
Agreement, the "Senior Credit Agreements") with Texas Commerce Bank National
Association, as agent bank for a syndicate of lenders, and Credit Suisse First
Boston and Chase Securities Inc. as co-arrangers. Funding under the New Credit
Agreement occurred January 31, 1997, upon consummation of the AFB Acquisition.
The New Credit Agreement provides for a term loan facility consisting of a $31
million Tranche A term loan due June 30, 2003, and a $50 million Tranche B term
loan due September 30, 2004 (the "New Term Loans" and together with the Original
Term Loans, the "Term Loans").

     The Term Loans, the ESOP Loan and the Revolver borrowings bear interest, at
Chemicals' option, at an annual rate of either the Eurodollar Rate or the Base
Rate plus an Applicable Margin ranging from 0% to 3% depending 

                                       12
<PAGE>
 
upon the Company's Leverage Ratio (as defined in the Original Credit Agreement).
The "Base Rate" is equal to the greater of the Prime Rate as announced from time
to time by the agent bank, the "Federal Funds Effective Rate" plus 1/2% or the
"Base CD Rate" plus 1% (as such terms are defined in the Senior Credit
Agreements). The Original Credit Agreement also requires Chemicals to pay a
commitment fee in the amounts of 3/8% or 1/2% of the unused commitment under the
Revolver depending on the Company's Leverage Ratio.

     On April 7, 1997, Chemicals completed a private offering (the "11 1/4%
Notes Offering") of $150,000,000 of 11 1/4% Senior Subordinated Notes Due 2007
(the "11 1/4% Notes"). The 11 1/4% Notes are unsecured senior subordinated
obligations of Chemicals, ranking subordinate in right of payment to all
existing and future senior debt of Chemicals, but pari passu with the 11 3/4%
Notes and all future senior subordinated indebtedness. On July 7, 1997,
Chemicals completed a registered exchange offer, pursuant to which all of the 
11 1/4% Notes were exchanged for publicly registered 11 1/4% Notes with
substantially similar terms.

     The proceeds of the 11 1/4% Notes Offering were used to prepay outstanding
indebtedness under the Term Loans. In connection with such prepayments,
Chemicals and the requisite lenders under the Senior Credit Agreements effected
amendments to the Senior Credit Agreements ("the Amendments"). Among other
things, the Amendments (i) permitted and provided for the issuance of the 
11 1/4% Notes, (ii) adjusted the method of the application of voluntary
prepayments to allow the proceeds of the 11 1/4% Notes Offering to be applied in
a manner that significantly reduced required principal payments, particularly
over the next three years, (iii) amended certain financial covenants to make
them somewhat less restrictive, including amendments to ratios specified in the
Amendments, (iv) increased the commitment under the Revolver by $25 million to
$125 million and (v) included a new financial covenant with respect to the
maintenance of a specified Senior Debt Leverage Ratio (as defined in the
Amendments). Unamortized debt issue costs related to the Term Loans of
approximately $6.0 million pre-tax, $3.9 million after-tax, were expensed in
April 1997 and recorded as an extraordinary loss from early extinguishment of
debt.


5. COMMITMENTS AND CONTINGENCIES:

Product Contracts

     The Company has certain long-term agreements that provide for the
dedication of 100% of the Company's production of acetic acid, plasticizers,
tertiary butylamine, and sodium cyanide, each to one customer. The Company also
has various sales and conversion agreements that dedicate significant portions
of the Company's production of styrene monomer, acrylonitrile, and methanol, the
Company's major petrochemical products, to various customers. These agreements
generally provide for cost recovery plus an agreed margin or element of profit
based upon market price.

Environmental Regulations

     The Company's operations involve the handling, production, transportation
and disposal of materials classified as hazardous or toxic and are extensively
regulated under environmental and health and safety laws. Operating permits
which are required for the Company's operations are subject to periodic renewal
and may be revoked or modified for cause. New laws or permit requirements and
conditions may affect the Company's operations, products, or waste disposal.
Past or future operations may result in claims or liabilities. Expenditures
could be required to upgrade waste water collection, pretreatment, or disposal
systems or for other matters related to production, transportation and disposal
of materials classified as hazardous or toxic.

Legal Proceedings

     Ammonia Release Lawsuits. A description of the ammonia release lawsuit is
found under "Legal Proceedings" in Note 7 of the "Notes To Consolidated
Financial Statements" of the Annual Report and is incorporated herein by
reference. As discussed therein, approximately 2,600 of the plaintiffs agreed to
submit their damage claims to binding arbitration. Each of the plaintiffs who
agreed to participate in the arbitration waived any right of recovery for
punitive or exemplary damages. Pursuant to the agreement to arbitrate, a two-
week evidentiary proceeding was conducted in July 1996 before a three-judge
panel to determine the amount of damages. On May 1, 1997, the three-judge panel
awarded the plaintiffs an amount of damages which was well within the limits of
the Company's 

                                       13
<PAGE>
 
insurance coverages and will not have a material adverse impact on the financial
position, results of operations, or cash flows of the Company.

     The Company continues to vigorously defend against the claims of the
plaintiffs who did not participate in the July 1996 arbitration.

     Other Lawsuits. The Company is subject to various other claims and legal
actions that arise in the ordinary course of its business.

Litigation Contingency

     In accordance with Statement of Financial Accounting Standards No. 5,
"Accounting for Contingencies," and Financial Accounting Standards Board
Interpretation No. 39, "Offsetting of Amounts Related to Certain Contracts," the
Company has made estimates of the reasonably possible range of its liability
with regard to outstanding litigation for which it may incur liability. In
addition, liabilities have been accrued based on the estimated probable loss
from such litigation. These estimates are based on management's judgments using
currently available information as well as consultation with the Company's
insurance carriers and outside legal counsel. A number of the claims in these
litigation matters are covered by the Company's insurance policies. The Company
therefore has also made estimates of its probable recoveries under these
insurance policies based on its understanding of these policies, discussions
with its insurers and consultation with outside legal counsel, in addition to
management's judgments. Based on the foregoing, as of June 30, 1997, the Company
has accrued approximately $15.6 million as its estimate of aggregate contingent
liability for these matters, and has also recorded aggregate receivables from
its insurers of approximately $15.0 million. At June 30, 1997, management
estimates that the aggregate reasonably possible range of loss for all
litigation combined, in addition to the amount accrued, is from $0 to $20
million. The Company believes that this additional reasonably possible loss is
substantially covered by insurance.

     While the Company has based its estimates on its evaluation of available
information to date and the other matters described above, much of the
litigation is in its early stages and it is impossible to predict with certainty
the ultimate outcome. The Company will adjust its estimates as necessary as
additional information is developed and evaluated. However, the Company believes
that the final resolution of these contingencies will not have a material
adverse impact on the financial position, results of operations, or cash flows
of the Company. The timing of probable insurance recoveries, and additional
accruals or payment of liabilities, if any, are not expected to have a material
adverse effect on the financial position, results of operations, or cash flows
of the Company.


6. NEW ACCOUNTING STANDARDS:

     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed Of." This statement
establishes new accounting standards for measuring the impairment of long-lived
assets. The Company adopted this Statement in the first quarter of fiscal 1997.
The adoption of this Statement did not have a material adverse effect on the
Company's financial position, results of operations, or cash flows.

     The Financial Accounting Standards Board issued SFAS No. 123, "Accounting
for Stock-Based Compensation" in October 1995. Under SFAS No. 123, companies are
permitted to either adopt this new standard and record expenses for stock
options and other stock-based employee compensation plans based on their fair
value at date of grant, or continue to apply its current accounting policy under
Accounting Principles Board ("APB") Opinion No. 25 and increase its footnote
disclosure. In the first quarter of fiscal 1997, the Company elected to continue
to apply APB Opinion No. 25, and will increase its footnote disclosure to
include the pro forma impact on net income and earnings per share of the
application of the fair value based method of accounting.

     The Financial Accounting Standards Board issued SFAS No. 128, "Earnings Per
Share," in February 1997. SFAS No. 128, which is effective for periods ending
after December 15, 1997, establishes standards for computing and presenting
earnings per share ("EPS"). SFAS No. 128 replaces the presentation of primary
EPS previously prescribed by APB No. 15 with a presentation of basic EPS, which
is computed by dividing income available to common stockholders by the weighted
average number of common shares outstanding for the period. The statement also
requires dual presentation of basic and diluted EPS. Diluted EPS is computed
similarly to fully diluted EPS 

                                       14
<PAGE>
 
pursuant to APB No. 15. Pro forma basic and diluted EPS for all historical
periods presented, assuming that SFAS No. 128 was effective at the beginning of
each such historical period, would not be materially different from what has
been presented using APB No. 15.

     In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income," ("SFAS No. 130") and Statement No. 131,
"Disclosures About Segments of an Enterprise and Related Information," ("SFAS
No. 131"). SFAS No. 130 and SFAS No. 131 are effective for fiscal years
beginning after December 15, 1997. SFAS No. 130 establishes standards for
reporting and displaying of comprehensive income and its components. SFAS No.
131 establishes standards for the way that public business enterprises report
information about operating segments in interim and annual financial statements.
These two statements will have no effect on the Company's 1997 financial
statements, but management is currently evaluating what, if any, additional
disclosures may be required when these two statements are adopted in the first
quarter of fiscal 1999.


7. BUSINESS ACQUISITIONS:

     On January 31, 1997, the Company acquired the AFB from Cytec. The AFB, now
owned by two wholly owned subsidiaries of the Company (collectively "Sterling
Fibers"), recorded sales of approximately $139 million in calendar year 1996 and
consists of an acrylic fibers plant located near Pensacola, Florida, and several
associated marketing and research offices. Sterling Fibers is one of two acrylic
fibers manufacturers in the United States. Cytec will supply acrylonitrile to
Sterling Fibers through the continuation of a five-year supply agreement ending
in 2002. The acquisition was financed through the incurrence of $81 million of
term debt under the New Credit Agreement with substantially the same lenders as
those under the Original Credit Agreement, the issuance of $10 million
(liquidation value) of Series A "pay in kind" mandatory redeemable preferred
stock ("Series A Preferred") to Cytec, and the sale of $10 million of Holdings
Common Stock in a private placement. The Company used the purchase method to
account for the acquisition, and operating results of Sterling Fibers beginning
February 1, 1997 are included with those of the Company.

  The following table presents the unaudited pro forma results of operations of
the Company as if the AFB Acquisition had occurred on October 1, 1995. The pro
forma results have been prepared for comparative purposes only and do not
purport to be indicative of what would have occurred had the AFB Acquisition
been made at the beginning of fiscal year 1996 or of results which may occur in
the future (in thousands, except per share amounts).

     On July 10, 1997, Sterling Pulp Chemicals (Sask) Ltd. ("Sterling Sask"), an
indirect wholly owned subsidiary of Holdings and Chemicals, acquired
substantially all of the assets of Saskatoon Chemicals Ltd. ("Saskatoon
Chemicals"), a subsidiary of Weyerhaeuser Canada Ltd. (the "Saskatoon
Acquisition"). The acquired assets include a manufacturing plant near Saskatoon,
Saskatchewan, and were used by Saskatoon Chemicals to manufacture sodium
chlorate, caustic soda, calcium hypochlorite, chlorine, and hydrochloric acid.
Total consideration of $69.2 million was financed with (i) approximately $54.6
million under a new credit facility established by Sterling Sask with a group of
lenders, (ii) approximately $7.3 million pursuant to a private placement of
Holdings Common Stock, and (iii) approximately $7.3 million pursuant to a
private placement of Units, each Unit consisting of shares of Holdings' newly
authorized Cumulative Redeemable Preferred Stock, Series B ("Series B
Preferred") and Warrants to purchase shares of Holdings Common Stock. The
Saskatoon Acquisition will be accounted for under the purchase method of
accounting for financial reporting purposes during the fourth quarter of fiscal
1997.

8. EMPLOYEE BENEFITS:

Omnibus Stock Awards and Incentive Plan

     In April 1997, the Board of Directors, upon recommendation of the
Compensation Committee, but subject to shareholder approval at the next
stockholders meeting, approved the establishment of the Omnibus Stock Awards and
Incentive Plan (the "Omnibus Plan"). Under the Omnibus Plan, the Company may
grant to key employees, incentive and nonqualified stock options, stock
appreciation rights, restricted stock awards, performance awards, and phantom
stock awards. The terms and amounts of the awards will be determined by the
Compensation Committee of the Board of Directors. One million shares of the
Company's stock are reserved for issuance under the Omnibus Plan. In the event
of a change of control of the Company or a qualified public offering of Holdings
Common Stock, all awards will immediately vest and become exercisable.

     In July 1997, the Company granted approximately 260,000 stock options to
key employees of the Company with an exercise price of $12.00 per share. The
options vest 20% per year beginning on January 1, 1998, and are exercisable
through January 1, 2007.


Nonqualified Stock Option Plan for Non-Employee Directors

     Also in April 1997, the Board of Directors, upon recommendation of the
Compensation Committee, approved the establishment of the Nonqualified Stock
Option Plan for Non-Employee Directors (the "Nonqualified Plan"). Each non-
employee director of the Company is eligible to participate in the Nonqualified
Plan. Each eligible director on the date of adoption of the Nonqualified Plan
will be granted an option to acquire 2,000 shares of Holdings Common Stock
(4,000 shares for the Vice-Chairman), and each eligible director who is serving
on the Board of Directors on each subsequent October 1st will automatically be
granted an option to acquire 1,000 shares of Holdings Common Stock (2,000 shares
for the Vice-Chairman). All options will expire ten years from date of grant.
All options will be granted at the fair market value on the date of grant. A
total of 160,000 shares of Holdings Common Stock are reserved for issuance under
the Nonqualified Plan.
                                                                                
     Effective April 1997, the Company granted 14,000 stock options to non-
employee directors of the Company with an exercise price of $12.00 per share.
The options are exercisable immediately and expire on the tenth anniversary of
the date of grant.


Profit Sharing and Bonus Plan

     In January 1997, the Board of Directors, upon recommendation of the
Compensation Committee, approved the establishment of a Profit Sharing Plan that
is designed to benefit all qualified employees, and a Bonus Plan that is
expected to provide for bonuses to certain key employees based on the Company's
annual financial performance.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders
of Sterling Chemicals Holdings, Inc.

     We have reviewed the accompanying condensed consolidated balance sheet of
Sterling Chemicals Holdings, Inc. and subsidiaries (the "Company") as of June
30, 1997, and the related condensed consolidated statements of operations and
cash flows for the three-month and nine-month periods then ended. These
financial statements are the responsibility of the Company's management.

     We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.

     Based on our review, we are not aware of any material modifications that
should be made to the condensed consolidated financial statements referred to
above for them to be in conformity with generally accepted accounting
principles.

     We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of the Company as of September 30,
1996, and the related consolidated statements of operations, stockholders'
equity, and cash flows for the year then ended (not presented herein); and in
our report dated December 6, 1996, we expressed an unqualified opinion on those
consolidated financial statements. In our opinion, the information set forth in
the accompanying condensed consolidated balance sheet as of September 30, 1996
is fairly stated in all material respects, in relation to the consolidated
balance sheet from which it has been derived.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

Certain capitalized terms used herein have the meanings assigned to them in the
Notes To Condensed Consolidated Financial Statements.


OVERVIEW

     Holdings is a holding company whose only material asset is its investment
in Chemicals. Chemicals and its subsidiaries own substantially all of the
consolidated operating assets and are obligated for substantially all
liabilities of the Company other than the 13 1/2% Notes which are an obligation
of Holdings. The Merger that occurred on August 21, 1996, and related financings
were accounted for as a recapitalization, with no change in the basis of the
assets and liabilities of Chemicals. Other than the additional interest expense
associated with the 13 1/2% Notes and the preferred stock dividend associated
with the Series A Preferred issued to Cytec, the results of operations for the
Company are essentially the same as those for Chemicals. Accordingly, the
discussion that follows is applicable to both entities, except as specifically
noted. A separate discussion of the results of operations for Chemicals for the
three month and nine month periods ended June 30, 1997 would not, in the opinion
of the Company, provide any additional meaningful information.


RECENT DEVELOPMENTS

     On July 29, 1997, the methanol production facility at the Texas City Plant
was shut down due to operating problems. Repairs are ongoing, and production at
the facility is expected to resume in September 1997. Financial results for the
fourth fiscal quarter ending September 30, 1997 will be negatively impacted by
the shut down; however, the shut down is not expected to have a material adverse
effect on the Company's results of operations for the fiscal year ended
September 30, 1997. No assurance can be given that the shut down, should it
continue longer than expected, will not have a material adverse effect on the
Company. The shut down does not materially affect the operation of any other
facilities at the Texas City Plant.

     On July 23, 1997, the Company announced the signing of a non-binding letter
of intent with W.K. Croxton (Pty) Ltd. to form a joint venture that would
construct a sodium chlorate plant in South Africa. Formation of the venture and
construction of the plant are subject to numerous conditions, and no assurances
can be given that either will occur.

     On July 10, 1997, Sterling Sask, an indirect wholly owned subsidiary of
Holdings and Chemicals, acquired substantially all of the assets of Saskatoon
Chemicals, a subsidiary of Weyerhaeuser Canada Ltd. Sterling Sask was
established in connection with the Saskatoon Acquisition and was designated as
an Unrestricted Subsidiary under the indentures governing the 13 1/2% Notes, the
11 3/4% Notes, and the 11 1/4% Notes (the "Indentures"). The acquired assets
include a manufacturing plant near Saskatoon, Saskatchewan, and were used by
Saskatoon Chemicals to manufacture sodium chlorate, caustic soda, calcium
hypochlorite, chlorine, and hydrochloric acid. Total consideration of $69.2
million was financed with (i) approximately $54.6 million under a new credit
facility established by Sterling Sask with a group of lenders, (ii)
approximately $7.3 million pursuant to a private placement of Holdings Common
Stock, and (iii) approximately $7.3 million pursuant to a private placement of
Units, each Unit consisting of shares of Series B Preferred Stock and Warrants
to purchase shares of Holdings Common Stock. The Saskatoon Acquisition will be
accounted for under the purchase method of accounting for financial reporting
purposes during the fourth quarter of fiscal 1997.

     On April 7, 1997, Chemicals completed its private offering of $150,000,000
of 11 1/4% Notes. The 11 1/4% Notes are unsecured senior subordinated
obligations of Chemicals, ranking subordinate in right of payment to all
existing and future senior debt of Chemicals, but pari passu with the 11 3/4%
Notes and all future senior subordinated indebtedness. On July 7, 1997,
Chemicals completed a registered exchange offer, pursuant to which all of the 11
1/4% Notes were exchanged for publicly registered 11 1/4% Notes with
substantially similar terms.

     The proceeds of the 11 1/4% Notes Offering were used to prepay outstanding
indebtedness under the Term Loans. In connection with such prepayments,
Chemicals and the requisite lenders under the Senior Credit Agreements effected
the Amendments. Among other things, the Amendments (i) permitted and provided
for the issuance of the 11 1/4% Notes, (ii) adjusted the method of the
application of voluntary prepayments to allow the proceeds of the 11 1/4% Notes
Offering to be applied in a manner that significantly reduced required principal
payments, particularly over the next three years, (iii) amended certain
financial covenants to make them somewhat less restrictive, including amendments
to specific ratios specified in the Amendments, (iv) increased the commitment
under the Revolver by $25 million to $125 million, and (v) included a new
financial covenant with respect to the maintenance of a specified Senior Debt
Leverage Ratio (as defined in the Amendments).  Unamortized debt issue costs
related to the Term Loans of approximately $6.0 million pre-tax, $3.9 million
after-tax, were expensed in April 1997 and recorded as an extraordinary loss
from early extinguishment of debt.

RESULTS OF OPERATIONS

     Consolidated revenues increased for the three and nine month periods ending
June 30, 1997, compared to the same periods in fiscal 1996. The primary reasons
for these increased revenues were five months of operations from the recently
acquired AFB, increased volumes for sodium chlorate, due in part to the startup
of the Company's new sodium chlorate plant in Valdosta, Georgia (the "Valdosta
Plant"), and revenues from the Company's new methanol unit at the Texas City,
Texas plant (the "Texas City Plant"). Consolidated net income (loss) was lower
due to lower petrochemical margins (primarily styrene), along with an increase
of interest expense to $23.9 million and $63.4 million for the three and nine
month periods of 1997, respectively, compared to $1.2 million and $4.4 million,
respectively, for the same periods last year.

     Revenues for the third quarter of fiscal 1997 were $239.2 million compared
to revenues of $218.4 million for the third quarter of fiscal 1996, an increase
of 10%. A net loss of $9.6 million, or $0.84 per share, was recorded for the
third quarter of fiscal 1997 compared to net income of $16.4 million, or $0.29
per share, for the third quarter of fiscal 1996. Included in the third quarter
of 1997 net loss was an extraordinary pre-tax charge of $6.0 million, or $3.9
million after-tax, related to the write-off of unamortized debt issue costs as a
result of the partial prepayment of the Term Loans with proceeds of the 11 1/4%
Notes Offering.

     Revenues for the first nine months of fiscal 1997 were $665.9 million
compared to revenues of $600.8 million for the first nine months of fiscal 1996,
an increase of nearly 11%. A net loss of $24.8 million or $2.24 per share was
recorded for the first nine months of fiscal 1997 compared to net income of
$35.6 million or $0.64 per share for the first nine months of fiscal 1996.
Included in the nine months of fiscal 1997 net loss was an extraordinary pre-tax
charge of $6.0 million, or $3.9 million after-tax, related to the write-off of
unamortized debt issue costs as a result of the partial prepayment of the Term
Loans.

Petrochemicals

     Petrochemical business revenues for the three months ending June 30, 1997,
were $163.8 million as compared to $180.5 million in the prior year period.  The
9% decrease in revenues was primarily due to reduced acrylonitrile and styrene
volumes, partially offset by the positive impact of the new methanol unit.  The
nine months ending June 30, 1997, revenues were $482.6 million as compared to
$487.3 million in the same period of 1996.  The 1% decrease in revenues was
primarily due to reduced acrylonitrile and styrene volumes, mostly offset by the
positive impact of the new methanol unit.  The Company's petrochemical business
recorded operating income of $5.1 million and an operating loss of $1.5 million,
respectively, for the three and nine month periods of 1997 compared to operating
income of $15.4 million and $30.0 million, respectively, for the same periods of
fiscal 1996.  The decrease in operating earnings for the third quarter was
primarily due to lower styrene and acrylonitrile volumes and lower styrene
margins.  The decrease in operating earnings for the nine month period was
primarily due to lower styrene and acrylonitrile margins.

     Styrene.   Styrene revenues decreased 9% to  $79.1 million in the third
quarter of fiscal 1997 and 2% to $244.1 million for the first nine months of
fiscal 1997 compared to the same periods in fiscal 1996. Styrene sales prices
decreased moderately from the same fiscal 1996 periods because of weaker market
conditions, particularly in the export market. Average sales prices for both the
third quarter and first nine months of fiscal 1997 decreased by approximately 1%
from the same periods a year ago. Sales volumes for both the three and nine
month periods decreased 10% and 4%, respectively, when compared to the same
periods last year.

     The prices of styrene's major raw materials, benzene and ethylene, were
higher during the third quarter and first nine months of fiscal 1997 compared to
the same periods in fiscal 1996. Benzene prices were approximately 6% and 19%
higher, and ethylene prices were approximately 12% and 24% higher, for the
respective 1997 periods compared to 1996. These price escalations contributed
significantly to the decline in styrene margins as market conditions did not
allow for sufficient styrene price increases to compensate for these rising
costs.

     Acrylonitrile. Acrylonitrile revenues decreased 26% to $35.9 million in the
third quarter of fiscal 1997 and 16% to $103.8 million for the first nine months
of fiscal 1997 compared to the same periods in fiscal 1996. The decreased
revenues in both periods were primarily due to reduced volumes of 27% and 5%,
respectively, for the three and nine months of 1997 as compared to the same
periods of 1996. The 27% reduction in volumes in the third quarter of 1997 were
primarily due to the partial shutdown of production as a result of operating
difficulties 

                                       21
<PAGE>
 
following the completion of a capital project. In addition, the reduced revenues
in the nine month period of fiscal 1997 were impacted by a 12% decrease in the
average acrylonitrile sales price realized by the Company.

     The prices of acrylonitrile's major raw materials, propylene and ammonia,
were approximately 16% and (1)% higher (lower), respectively, in the third
quarter and 17% and 12% higher, respectively, for the first nine months of
fiscal 1997 than for the corresponding periods in fiscal 1996. These increases
contributed to the decline in acrylonitrile margins.

     Methanol. Methanol revenues for the third quarter of 1997 were $20.6
million, bringing the total revenues for the first nine months of fiscal 1997 to
$52.5 million. Margins improved significantly in the third quarter as the price
of natural gas (the primary raw material for methanol) declined significantly
without a corresponding drop in the price of methanol. In addition, the methanol
unit benefited from operating at 112% of capacity. The methanol unit was under
construction during the corresponding periods of 1996. 

     Other Petrochemical Products. Revenues from the Company's other
petrochemical products (including acetic acid, plasticizers, tertiary
butylamine, and sodium cyanide) in the third quarter of fiscal 1997 were $28.2
million, a decrease of 37% when compared to the same period last year. Revenues
for the nine month period ended June 30, 1997 were down 28% to $82.2 million
when compared to the same 1996 period. The decrease in revenues in both periods
was primarily due to a decline in acetic acid revenues resulting from a
procedural change in the billings under the Company's production contract with
BP Chemicals Inc. ("BP") and the recording of related revenues. Prior to the
startup of the Company's methanol unit, the Company purchased the methanol used
in the production of acetic acid. Under the BP contract, such purchases were
ultimately re-billed to BP and included in acetic acid revenues. Methanol for
acetic acid production is now supplied by the Company's methanol facility and is
included in methanol revenues.

Pulp Chemicals

     Revenues from the Company's pulp chemical business increased 9% to $41.0
million and 11% to $125.5 million for the third quarter and first nine months of
fiscal 1997, respectively, when compared to the same periods last year. The
increase in revenues was primarily due to an increase in sales volumes of sodium
chlorate of 22% and 14%, respectively, when compared to the corresponding three
and nine month periods of 1996. The increase in sales volumes in the third
quarter was aided by the startup of the Valdosta Plant in December 1996. Average
sales prices for sodium chlorate declined 7% in the third quarter of fiscal 1997
compared to the corresponding period in 1996. Average sodium chlorate sales
prices for the first nine months of 1997 were 2% lower than the corresponding
period in 1996.  Revenues from the sale of generators and royalty income
decreased 27% in the third quarter and increased 3% in the first nine months of
fiscal 1997 compared to the corresponding periods of 1996. This 27% decrease in
revenues in the third quarter of 1997 was primarily due to reduced project work
related to generators.  Operating earnings for the pulp chemicals business were
$10.9 million for the third quarter of fiscal 1997 compared to $10.4 million
during the corresponding period of 1996. Operating earnings for the pulp
chemicals business were $35.2 million for the first nine months of fiscal 1997
compared to $28.3 million for the corresponding period in 1996. The increase for
the three and nine month periods were primarily due to increased sales volumes
of sodium chlorate. In addition, the Company recorded $2.9 million of expenses
associated with stock appreciation rights for its pulp chemicals employees
during the nine months of fiscal 1996.

Fibers

     For the five-month period from February 1, 1997, to June 30, 1997, Sterling
Fibers recorded revenues and operating earnings of $57.8 million and $2.9
million, respectively. For the three months ended June 30, 1997, Sterling Fibers
recorded revenues and operating earnings of $34.4 million and $2.1 million,
respectively.  Because the Company did not acquire the assets constituting the
AFB prior to January 31, 1997, there are no corresponding results for prior
periods.


Selling, General, and Administrative Expenses

     Selling, general, and administrative ("SG&A") expense increased to $11.0
million during the third quarter of fiscal 1997 as compared to $7.7 million in
the comparable period of fiscal 1996.  The $3.3 million increase was primarily
due to AFB SG&A expense recorded since the acquisition in January 1997. SG&A
expenses for the first nine months of fiscal 1997 were $24.3 million compared to
$23.8 million in the first nine months of fiscal 1996. The 

                                       22
<PAGE>
 
$0.5 million increase was primarily due to AFB SG&A expense recorded since the
acquisition in January 1997, mostly offset by a sales tax refund in 1997 and
lower employee profit sharing and other overheads.

Interest and Debt Related Expense

     Interest and debt related expenses for the three and nine month periods
ending June 30, 1997, were $23.9 million and $63.4 million, respectively,
compared to $1.2 million and $4.4 million, respectively, for the corresponding
periods in 1996. This increase is primarily due to the additional debt incurred
in the 1996 Recapitalization and the AFB Acquisition.

Extraordinary Item

     The $3.9 million after-tax ($6.0 million pre-tax) extraordinary item
relates to unamortized debt issue costs which were expensed in April 1997 as a
result of the partial prepayment of the Term Loans.


LIQUIDITY AND CAPITAL RESOURCES

Debt Structure

     On August 21, 1996, the Company completed the 1996 Recapitalization,
significantly increasing the Company's leverage and cash requirements for debt
service related to the Original Credit Agreement, the 13 1/2% Notes and the 11
3/4% Notes.  In connection with the AFB Acquisition, Chemicals entered into the
New Credit Agreement, which was funded on January 31, 1997, upon consummation of
the AFB Acquisition.  On April 7, 1997, Chemicals completed the 11 1/4% Notes
Offering, the proceeds of which were used to partially repay the Term Loans.  At
June 30, 1997, the Company's long-term debt (including current maturities) was
$842.2 million.

     The Company's ability to obtain additional financing in the future for
working capital, capital expenditures, acquisitions and general corporate
purposes, should it need to do so, will be affected by the covenants in its
various debt agreements and by cash requirements for debt service. The Senior
Credit Agreements and the Indentures contain numerous financial and operational
covenants, including, without limitation, restrictions on the Company's ability
to incur indebtedness, pay dividends, create liens, sell assets, engage in
mergers and acquisitions, and refinance existing indebtedness, as well as the
obligation of the Company to maintain certain financial ratios. As of June 30,
1997, these restrictions currently operate to prevent the Company from incurring
any additional debt other than debt incurred under the Revolver or pursuant to
certain limited "baskets" and other exceptions. The 11 1/4% Notes Offering was
permitted under the Indentures as a Refinancing of Debt outstanding under the
Senior Credit Agreements. The Indentures will also permit the Company to
consummate acquisitions if the pro forma effect of such an acquisition has
sufficient positive impact on certain financial ratios. In addition, under
limited circumstances the Company may make acquisitions through the incurrence
of debt in Unrestricted Subsidiaries (as defined in the Indentures). The
financing for the Saskatoon Acquisition was structured in this manner. The
Senior Credit Agreements also require that certain amounts of Excess Cash Flow
(as defined therein) be used to prepay amounts outstanding under the Term Loans.
The first such mandatory prepayment, if any, is not required to be made until
January 1998. The Company's ability to comply with the terms of its various debt
agreements (including its ability to comply with such covenants) and to meet its
debt service obligations will depend on its future performance. The Company was
in compliance with its financial covenants (as amended) in effect as of June 30,
1997.

     The Company intends to meet its liquidity needs for operating activities
and capital expenditures (other than acquisitions) through internally generated
funds and, to the extent necessary, borrowings under the Revolver. As part of
the Amendments, on April 7, 1997, the total commitment under the Revolver was
increased by $25 million to $125 million. The Company believes that such sources
of funds will be sufficient to permit the Company to meet its liquidity needs
during fiscal 1997. As of June 30, 1997, Chemicals had drawn approximately $26.8
million under the Revolver and issued approximately $2.0 million in letters of
credit under the Revolver, thereby reducing the available commitment under the
Revolver at such time to approximately $96.2 million (compared to an available
commitment thereunder as of March 31, 1997 of $77.4 million).

     The Senior Credit Agreements and the indentures for the 11 3/4% Notes and
the 11 1/4% Notes contain provisions which restrict the payment of advances,
loans, and dividends from Chemicals to Holdings. The most restrictive of those
covenants limit such payments during fiscal 1997 to approximately $1.6 million
plus any amounts due to 

                                       23
<PAGE>
 
Holdings from Chemicals under an intercompany tax sharing agreement. Such
restriction is not expected to limit Holdings' ability to meet its obligations
in fiscal 1997.

Working Capital

     Working capital of the Company was $138.9 million at June 30, 1997, up from
$76.9 million at September 30, 1996. The $62.0 million increase in working
capital was primarily due to the addition of the AFB which contributed
approximately $29 million to total working capital and an increase in pulp and
petrochemicals accounts receivables partially due to the Valdosta Plant, the new
methanol plant, profit sharing accruals under the plasticizers sales agreement
with BASF and business terms and timing of collections.

Cash Flow

     Net cash provided by operations was $11.5 million during the first nine
months of fiscal 1997 compared to $31.4 million for the corresponding period in
fiscal 1996. The decrease was primarily attributable to higher payments for
interest and lower operating earnings.

Capital Expenditures

     The Company's capital expenditures for the first nine months of fiscal 1997
were $32.6 million compared to $73.0 million in the same period last year. The
capital expenditures in the first nine months of fiscal 1997 were primarily
related to the construction of the Valdosta Plant of $13.0 million, along with
the distributive control system upgrade at the Company's acrylonitrile unit.
During the remainder of fiscal 1997, the Company expects to make an additional
$6 million to $8 million of capital expenditures primarily for process
modernization in styrene and acrylonitrile and routine safety, environmental,
and replacement capital in the Company's petrochemical, pulp chemical, and
fibers businesses. The Company expects to fund its remaining fiscal 1997 capital
expenditures from operating cash flow, plus borrowings under the Revolver, if
needed.

                                 --------------

       Section 2.01.  Authorized Capital.  (a) The total number of shares of
stock that the Corporation shall have the authority to issue is 22,000,000
shares of capital stock, consisting of (i) 2,000,000 shares of preferred stock,

which is expressly authorized to fix the same in its absolute discretion subject
to the foregoing conditions.  Shares so issued for which the consideration shall

and shall not be liable to any further call or assessment thereon, and the
holders of such shares shall not be liable for any further payments in respect
of such shares.

       (c) The right to cumulate votes for the election of directors as provided

<PAGE>
 
       Section 2.02.  Preferred Stock.  (a)  The Preferred Stock may be issued
from time to time in one or more series.  Authority is hereby expressly granted
to and vested in the Board of Directors to authorize from time to time the

of Preferred Stock authorized by it, the Board of Directors shall be authorized
to establish by resolution or resolutions, and by filing a certificate pursuant
to the applicable law of the State of Delaware (a "Preferred Stock
Designation"), the following to the fullest extent now or hereafter permitted by
the DGCL:

          (i) the designation of such series;

         (ii) the number of shares to constitute such series;

        (iii) whether such series is to have voting rights (full, special or
   limited) or is to be without voting rights;

         (iv) if such series is to have voting rights, whether or not such
   series is to be entitled to vote as a separate class either alone or together
   with the holders of the Common Stock or one or more other series of Preferred
   Stock;

          (v) the preferences and relative, participating, optional, conversion
   or other special rights (if any) of such series and the qualifications,
   limitations or restrictions (if any) with respect to such series;

         (vi) the redemption rights and price(s), if any, of such series, and
   whether or not the shares of such series shall be subject to the operation of
   retirement or sinking funds to be applied to the purchase or redemption of
   such shares for retirement and, if such retirement or sinking funds or funds
   are to be established, the periodic amount thereof and the terms and
   provisions relative to the operation thereof;

        (vii) the dividend rights and preferences (if any) of such series,
   including, without limitation, (A) the rates of dividends payable thereon,
   (B) the conditions upon which and the time when such dividends are payable,
   (C) whether or not such dividends shall be cumulative or noncumulative and,
   if cumulative, the date or dates from which such dividends shall accumulate
   and (D) whether or not the payment of such dividends shall be preferred to
   the payment of dividends payable on the Common Stock or any other series of
   Preferred Stock;

       (viii) the preferences (if any), and the amounts thereof, which the
   holders of such series shall be entitled to receive upon the voluntary or
   involuntary liquidation, dissolution or winding-up of, or upon any
   distribution of the assets of, the Corporation;

         (ix) whether or not the shares of such series, at the option of the
   Corporation or the holders thereof or upon the happening of any specified
   event, shall be convertible into or 

                                      -3-
<PAGE>
 
   exchangeable for (A) shares of Common Stock, (B) shares of any other series
   of Preferred Stock or (C) any other stock or securities of the Corporation;

          (x) if such series is to be convertible or exchangeable, the price or
   prices or ratio or ratios or rate or rates at which such conversion or
   exchange may be made and the terms and conditions (if any) upon which such
   price or prices or ratio or ratios or rate or rates may be adjusted; and

         (xi) such other rights, powers and preferences with respect to such
   series as may to the Board of Directors seem advisable.

Any series of Preferred Stock may vary from any other series of Preferred Stock
in any or all of the foregoing respects and in any other manner.

       (b) The Board of Directors may, with respect to any existing series of
Preferred Stock but subject to the Preferred Stock Designation creating such
series, (i) increase the number of shares of Preferred Stock designated for such
series by a resolution adding to such series authorized and unissued shares of
Preferred Stock not designated for any other series or (ii) decrease the number
of shares of Preferred Stock designated for such series by a resolution
subtracting from such series shares of Preferred Stock designated for such
series (but not below the number of shares of such series then outstanding), and
the shares so subtracted shall become authorized, unissued and undesignated
shares of Preferred Stock.

       (c) No vote of the holders of the Common Stock or the Preferred Stock
shall, unless otherwise expressly provided in a Preferred Stock Designation, be
a prerequisite to the issuance of any shares of any series of the Preferred
Stock authorized by and complying with the conditions of this Certificate of
Incorporation.  Shares of any series of Preferred Stock that have been
authorized for issuance pursuant to this Certificate of Incorporation and that
have been issued and reacquired in any manner by the Corporation (including upon
conversion or exchange thereof) shall be restored to the status of authorized
and unissued shares of Preferred Stock and may be reissued as part of a new
series of Preferred Stock to be created by resolution or resolutions of the

therefor.

       (c) In the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the Corporation, after payment or provision for payment of the
debts and other liabilities of the Corporation, and subject to the preferential

<PAGE>
 
Preferred Stock in respect thereof, the holders of shares of the Common Stock

available for distribution to its stockholders, ratably in proportion to the
number of shares of the Common Stock held by them. For purposes of this

sale, lease, exchange or conveyance of all or a part of the assets of the
Corporation.

       Section 2.04.  Stock Options, Warrants, etc.  Unless otherwise expressly

Stock, the Corporation shall have authority to create and issue warrants, rights
and options entitling the holders thereof to purchase from the Corporation
shares of the Corporation's capital stock of any class or series or other
securities of the Corporation for such consideration and to such persons, firms
or corporations as the Board of Directors, in its sole discretion, may
determine, setting aside from the authorized but unissued stock of the
Corporation the requisite number of shares for issuance upon the exercise of
such warrants, rights or options.  Such warrants, rights and options shall be
evidenced by one or more instruments approved by the Board of Directors.  The
Board of Directors shall be empowered to set the exercise price, duration, time
for exercise and other terms of such warrants, rights or options; provided,
however, that the consideration to be received for any shares of capital stock
subject thereto shall not be less than the par value thereof.

Corporation shall from time to time be fixed exclusively by the Board of
Directors in accordance with, and subject to the limitations set forth in, the
bylaws of the Corporation (the "Bylaws"); provided, however, that the Board of
Directors shall at all times consist of a minimum of three and a maximum of
fifteen members, subject, however, to increases above fifteen members as may
required in order to permit the holders of any series of Preferred Stock to
exercise their right (if any) to elect additional directors under specified
circumstances.  No decrease in the number of directors shall have the effect of
shortening the term of any incumbent director.  Anything in this Certificate of
Incorporation or the Bylaws to the contrary notwithstanding, each director shall
hold office until his successor is elected and qualified or until his earlier
death, resignation or removal.

       Section 3.02.  Nomination and Election.  (a) Nominations of persons for
election or reelection to the Board of Directors may be made by or at the
direction of the Board of Directors. The Bylaws may set forth procedures for the
nomination of persons for election or reelection to the Board of Directors and
only persons who are nominated in accordance with such procedures (if any) shall
be eligible for election or reelection as directors of the Corporation;
provided, however, that such procedures shall not infringe upon (i) the right of
the Board of Directors to nominate persons for election or reelection to the
Board of Directors or (ii) the rights of the holders of any series of 

                                      -5-

Preferred Stock, voting separately by class or series, to elect additional
directors under specified circumstances.

       (b) Each director shall be elected in accordance with this Certificate of
Incorporation, the Bylaws and applicable law.  Election of directors by the
Corporation's stockholders need not be by written ballot unless the Bylaws so
provide.

       Section 3.03.  Removal.  No director may be removed except by the
affirmative vote of the holders of not less than a majority in voting power of
all the outstanding shares of capital stock of the Corporation entitled to vote
generally in an election of directors, voting together as a single class. The
Board of Directors may not remove any director, and no recommendation by the

Directors.

       Section 3.04.  Vacancies.  (a) In case any vacancy shall occur on the
Board of Directors because of death, resignation or removal, such vacancy may be
filled only by a majority (or such higher percentage as may be specified in the
Bylaws) of the directors remaining in office (though less than a quorum), and
the director so appointed shall serve for the unexpired term of his predecessor
or until his successor is elected and qualified or until his earlier death,
resignation or removal.  If there are no directors then in office, an election
of directors may be held in the manner provided by applicable law.

       (b) Any newly-created directorship resulting from any increase in the
number of directors may be filled only by a majority (or such higher percentage
as may be specified in the Bylaws) of the directors then in office (though less
than a quorum).  Each director so appointed shall hold office until his
successor is elected and qualified or until his earlier death, resignation or
removal.

       (c) Except as expressly provided in this Certificate of Incorporation or
as otherwise provided by applicable law, stockholders of the Corporation shall
not have the right to fill vacancies or newly-created directorships on the Board
of Directors.

       Section 3.05.  Subject to Rights of Holders of Preferred Stock.
Notwithstanding the foregoing provisions of this Article III, if the Preferred
Stock Designation creating any series of Preferred Stock entitles the holders of
such Preferred Stock, voting separately by class or series, to elect additional
directors under specified circumstances, then all provisions of such Preferred
Stock Designation relating to the nomination, election, term of office, removal,
filling of vacancies and other features of such directorships shall, as to such
directorships, govern and control over any conflicting provisions of this
Article III.

       Section 3.06.  Limitation of Access of Stockholders to Books and Records.
In furtherance of, and not in limitation of, the powers conferred by law, the
Board of Directors is expressly authorized and empowered to determine from time

conditions and regulations, the accounts and books of the

Corporation, or any of them, shall be open to inspection of stockholders and,
except as so determined or as expressly provided in this Certificate of
Incorporation or in any Preferred Stock Designation, no stockholder shall have
any right to inspect any account, book or document of the Corporation other than
such rights as may be conferred by applicable law.

       Section 3.07.  Limitation of Personal Liability.  (a) No person who is or
was a director of the Corporation shall be personally liable to the Corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which
the director derived an improper personal benefit.

       (b) If the DGCL is hereafter amended to authorize corporate action
further limiting or eliminating the personal liability of directors, then the
personal liability of the directors to the Corporation or its stockholders shall
be limited or eliminated to the full extent permitted by the DGCL, as so amended
from time to time.

business for consideration at any meeting of stockholders but only as may be
expressly provided in, and then only in compliance with, the Bylaws.

       (c) Business transacted at any special meeting of stockholders shall be
limited to the purposes stated in the notice or waivers of notice of such

Section 3.1 or 3.2 hereof, such amounts shall be paid pro rata to each record
holder of shares of Preferred Stock in the proportion that the total number of
shares owned by such record holder bears to the total number of shares of
Preferred Stock then outstanding.

       Section 4.  Liquidation.  4.1.  Each share of Preferred Stock shall be
preferred over the shares of Junior Stock so that, in the event of any
Liquidation, each holder of Preferred Stock shall be entitled to receive out of
the assets of the Corporation available for distribution to its stockholders
(whether from capital, surplus or earnings), in preference to the holders of and
before any payment or distribution is made to the holders of shares of Junior
Stock upon such Liquidation, an amount in cash equal to (i) the Liquidation
Value plus an amount equal to all accrued and unpaid dividends thereon
(including any additional dividends accrued pursuant to Section 3.2 hereof) to
the date of final distribution multiplied by (ii) the number of outstanding
shares of Preferred Stock owned by such holder (such amounts with respect to all
shares of Preferred Stock, in the aggregate, the "Liquidation Payment").  If,
upon any Liquidation, the assets (or proceeds thereof) distributable among the
holders of Preferred Stock are insufficient to pay the Liquidation Payment in
full, then such assets (or the proceeds thereof) shall be distributable among
such holders ratably in accordance with the respective amounts which would be
payable on such shares if all amounts payable thereon were payable in full.

       4.2.    For the purposes of this Section 4, neither any merger or
consolidation involving the Corporation nor any sale, conveyance, exchange or
transfer (for cash, shares of stock, securities or other consideration) of all
or substantially all of the property or assets of the Corporation shall be
deemed to be a Liquidation, unless such sale, conveyance, exchange or transfer
shall be in connection with a plan of liquidation, dissolution or winding up of
the Corporation.

       4.3.    After the payment in cash to the holders of Preferred Stock of
the full amount of the Liquidation Payment with respect to all outstanding
shares of Preferred Stock, the holders of outstanding shares of Preferred Stock
shall have no right or claim, based solely on their ownership of shares of
Preferred Stock, to any of the remaining assets of the Corporation.

                                     A-iv
<PAGE>
 
       4.4.    In the event the assets of the Corporation available for
distribution to the holders of shares of Preferred Stock upon any Liquidation
shall be insufficient to pay the Liquidation Payment in full, no such
distribution shall be made on account of any shares of any Parity Stock upon
such Liquidation unless proportionate distributive amounts shall be paid on
account of all shares of the Preferred Stock, ratably, according to the
respective amounts which would be payable on the Preferred Stock and such Parity
Stock upon such Liquidation if all amounts payable thereon were paid in full.

       Section 5.  Redemption.  5.1.   The holder of any share of Preferred
Stock may, at his or its option, on any Dividend Payment Date occurring on or
after June 30, 2009, elect to have the Corporation redeem all or any number of
shares of Preferred Stock held by such holder, such election to be made by
providing written notice of such election and the number of shares of Preferred
Stock elected to be redeemed to the Corporation  (a "Holder Redemption Notice")
not less than 30 nor more than 90 days prior to the applicable Dividend Payment
Date. The Corporation shall, on the applicable Dividend Payment Date, redeem the
shares of Preferred Stock elected to be redeemed pursuant to such Holder
Redemption Notice and pay the holder of such shares the Redemption Price
therefor, provided that the Corporation has sufficient legally available funds
for such purpose.  In the event that the Corporation is required to redeem any
shares of Preferred Stock and does not have sufficient funds legally available
to redeem all of such shares, it shall use all of the funds that it does have
available for such purpose, if any, to redeem such number of shares of Preferred
Stock as is possible with such funds, pro rata, among all holders of Preferred
Stock which have previously provided the Corporation with a Holder Redemption
Notice and for which all or any portion of the shares of Preferred Stock elected
to be redeemed thereunder have not been redeemed. Any shares of Preferred Stock
which are not redeemed because the Corporation does not have sufficient funds
shall remain outstanding and the holders thereof shall continue to be entitled
to all the rights and benefits of holders of Preferred Stock under this
Designation of Rights.

       5.2.    In the event that the Corporation fails to pay any dividend in
respect of any shares of Preferred Stock on any Dividend Payment Date pursuant
to Section 3.1 or Section 3.3 hereof which the Corporation is not prohibited by
applicable law from declaring or paying, in addition to his or its rights
pursuant to Section 5.1 hereof, the holder of each such share of Preferred Stock
may, at his or its option, elect to have the Corporation redeem such share of
Preferred Stock by providing written notice of such election to the Corporation
(a "Holder Put Notice") within 30 days after the applicable Dividend Payment
Date, such election to specify the number of shares of Preferred Stock elected
to be redeemed.  Within 30 days after the receipt of any Holder Put Notice, the
Corporation shall redeem each share of Preferred Stock elected to be redeemed
pursuant to such Holder Put Notice which is eligible for redemption pursuant to
this Section 5.2 and pay the holder the Redemption Price therefor; provided,
however, that the Corporation shall not have any obligation to redeem any such
share of Preferred Stock if, prior to the expiration of such 30-day period, the
Corporation pays the dividend on such share that should have been paid for the
applicable Divided Payment Date (either in cash or in Additional Shares).  Any
shares of Preferred Stock which are not redeemed pursuant to the proviso to the
immediately preceding sentence shall remain outstanding and the holders thereof
shall continue to be entitled to all rights and benefits of holders of Preferred
Stock under this Designation of Rights.

                                      A-v
<PAGE>
 
       5.3.    The Corporation may, at its option, at any time and from time to
time, elect to redeem all or any number of shares of Preferred Stock, such
election to be made by providing written notice of such election and the number
of shares of Preferred Stock elected to be redeemed to the holders thereof (a
"Corporation Redemption Notice") not less than 10 days prior to the proposed
date of redemption (the "Redemption Date").  The Corporation shall, on the
applicable Redemption Date, redeem the shares of Preferred Stock elected to be
redeemed pursuant to such Corporation Redemption Notice and pay the holders of
such shares the Redemption Price therefor.  In the event that the Corporation
elects to redeem less than all of the shares of Preferred Stock, it shall redeem
the shares of Preferred Stock which it has elected to redeem, pro rata, among
all holders of Preferred Stock.

       5.4 The Corporation shall, from time to time, redeem shares of Preferred
Stock to the extent required pursuant to Section 6.3.

       5.5.    Upon any redemption of shares of Preferred Stock, the shares of
Preferred Stock so redeemed shall have the status of authorized and unissued
shares of preferred stock of the Corporation, unclassified as to series, and the
number of shares of preferred stock which the Corporation shall have authority
to issue shall not be decreased by the redemption of such shares of Preferred
Stock.

       Section 6.  Certain Restrictions.  6.1.  So long as the Corporation shall
be in default of any obligation to make any redemption pursuant to Section 5
hereof, the Corporation shall not, directly or indirectly, (a) declare or pay
any dividend or distribution on or with respect to any Junior Stock other than
solely in shares of Junior Stock or (b) declare or pay any dividend or
distribution on or with respect to any Parity Stock other than in shares of
Junior Stock or, with respect to any other dividends or distributions, except in
Parity Stock of the same class or series.

       6.2.    So long as any Additional Shares are outstanding or any accrued
dividends on the Preferred Stock are unpaid, the Corporation shall not, directly
or indirectly, (a) declare or pay any dividend or distribution on or with
respect to any Junior Stock other than solely in shares of Junior Stock or (b)
declare or pay any dividend or distribution on or with respect to any Parity
Stock other than in shares of Junior Stock or, with respect to any other
dividends or distributions, except in Parity Stock of the same class or series.

       6.3.    So long as any shares of Preferred Stock remain outstanding, the
Corporation shall not, directly or indirectly:

       (a) issue any additional shares of Preferred Stock (other than Additional
   Shares) or any shares of Prior Stock (including as a dividend or distribution
   on any securities);

       (b) (i) redeem, purchase or otherwise acquire or retire for value any
   Junior Stock or (ii) redeem, defease, purchase or otherwise acquire or retire
   for value (whether or not prior to scheduled maturity or scheduled sinking
   fund payment) any mandatory redemption, sinking fund or analogous obligation
   in respect of Junior Stock;

                                     A-vi
<PAGE>
 
       (c) (i) redeem, purchase or otherwise acquire or retire for value any
   Parity Stock unless a proportionate number of shares of Preferred Stock,
   rounded to the nearest whole share, are redeemed, purchased or otherwise
   acquired or retired for value, ratably, according to the respective amounts
   which would have been payable on the Preferred Stock and such Parity Stock
   upon a Liquidation if all amounts payable thereon were paid in full or (ii)
   redeem, defease, purchase or otherwise acquire or retire for value (whether
   or not prior to scheduled maturity or scheduled sinking fund payment) any
   mandatory redemption, sinking fund or analogous obligation in respect of
   Parity Stock unless proportionate amounts shall be paid on account of all
   shares of the Preferred Stock, ratably, according to the respective amounts
   which would be payable on the Preferred Stock and such Parity Stock upon a
   Liquidation if all amounts payable thereon were paid in full.

       (d) reclassify (by merger, consolidation or otherwise) any Junior Stock
   or Parity Stock as Prior Stock;

       (e) merge into or consolidate with any entity where the surviving or
   continuing corporation will have any outstanding Prior Stock other than
   capital stock corresponding to shares of Prior Stock of the Corporation
   issued before any agreement for such merger or consolidation; or

       (f) amend, alter or repeal by merger or otherwise any of the provisions
   of this Designation of Rights, the Certificate of Incorporation or the By-
   laws of the Corporation so as in any such case to adversely affect the voting
   powers, designations, preferences and relative, participating, optional or
   other special rights, and qualifications, limitations or restrictions of the
   shares of Preferred Stock;

provided, however, that nothing contained in this Designation shall be deemed or
construed to prohibit or restrict the right or ability of any employee stock
ownership plan of the Corporation or any of its subsidiaries to purchase or
otherwise acquire any shares of Junior Stock or any loan or other extension of
credit by the Corporation or any of its subsidiaries to any such employee stock
ownership plan.

       6.4 Notwithstanding anything to the contrary contained in this Section 6,
(a) at any time during which the Corporation is then in default of any
obligation to make any redemption pursuant to Section 5 hereof, the Corporation
may nevertheless, directly or indirectly, purchase shares of Junior Stock
covered by any employee stock ownership plan of the Corporation or any of its
subsidiaries existing on December 23, 1996 (the "ESOP") or a successor plan (i)
to the extent required by those provisions of the ESOP or any successor plan
that are no more favorable to the employees of the Corporation than the
provisions of the ESOP (a "Successor Plan") and (ii) to the extent required by
law, and (b) at any time during which the Corporation is not in default of any
obligation to make any redemption pursuant to Section 5 hereof, the Corporation
may, directly or indirectly, purchase:

                                     A-vii
<PAGE>
 
         (i) shares of Junior Stock from employees of the Corporation or any of
   its subsidiaries, former employees of the Corporation or any of its
   subsidiaries or the estates of deceased employees of the Corporation or any
   of its subsidiaries, or any party to the Stockholders Agreement of the
   Corporation dated August 21, 1996 (or his or its successors or permitted
   assigns) with an aggregate consideration paid by the Corporation in any
   fiscal year of the Corporation of less than or equal to $5,000,000; provided,
   however, that to the extent that the Corporation fails to resell any such
   shares of Junior Stock within one year after the date of purchase for
   consideration greater than or equal to the consideration paid by the
   Corporation for such shares, the Corporation shall, on the first anniversary
   of the purchase of such shares, redeem a number of shares of Preferred Stock,
   rounded to the nearest whole number, having an aggregate Redemption Price
   equal to the consideration paid by the Corporation for such shares of Junior
   Stock, if such shares have not been sold within such one year period, or the
   excess of the purchase price for such shares over the price for which such
   shares were resold, as applicable;

         (ii) shares of Junior Stock from employees of the Corporation or any of
   its subsidiaries, former employees of the Corporation or any of its
   subsidiaries or the estates of deceased employees of the Corporation or any
   of its subsidiaries; provided, however, that, if at any time the aggregate
   consideration paid by the Corporation, directly or indirectly, for the
   purchase of such shares of Junior Stock pursuant to this clause (ii) exceeds
   $1,000,000 in any fiscal year of the Corporation, the Corporation shall
   concurrently redeem a number of shares of Preferred Stock, rounded to the
   nearest whole number, with a Liquidation Value equal to the amount of such
   excess; and

         (iii)  shares of Junior Stock covered by the ESOP or any Successor Plan
   to the extent required by (A) the provisions thereof or (B) to the extent
   required by law.

       Section 7.  Voting.  7.1. The holders of shares of Preferred Stock shall
have no voting rights whatsoever, except for any voting rights to which such
holders may be entitled under applicable laws and except for the voting rights
set forth in the following provisions of this Section 7.

       7.2.    If and whenever at any time or times dividends payable on shares
of the Preferred Stock shall have been in arrears and unpaid in an aggregate
amount equal to or exceeding the amount of dividends payable thereon for two
Dividend Periods, then the number of directors constituting the Board shall be
increased by one and the holders of shares of the Preferred Stock shall have the
exclusive right (the "Special Voting Right"), voting separately as a class, to
elect one director of the Corporation.

       7.3.    The Special Voting Right may be exercised initially either by
written consent or at a special meeting of the holders of the Preferred Stock,
called as hereinafter provided, or at any annual meeting of stockholders held
for the purpose of electing directors, and thereafter at each such annual
meeting until such time as all dividends in arrears on shares of the Preferred
Stock shall have been paid in full (whether in cash or in Additional Shares), at
which time the Special Voting Right 

                                    A-viii
<PAGE>
 
and the term of the director elected pursuant to the exercise of the Special
Voting Right shall automatically terminate. Upon termination of the Special
Voting Right, the number of directors constituting the Board shall, without
further action, be reduced by one, subject always to increase as provided above
upon revesting of the Special Voting Right.

       7.4.    At any time when the Special Voting Right shall have vested and
if the Special Voting Right shall not already have been exercised by written
consent, a proper officer of the Corporation may call, and, upon the written
request, addressed to the Secretary of the Corporation, of the record holders of
shares representing 25% of the then outstanding shares of Preferred Stock, shall
call, a special meeting of the holders of Preferred Stock.  Such meeting shall
be held at the earliest practicable date upon the notice required for annual
meetings of stockholders at the place for holding annual meetings of
stockholders of the Corporation or, if none, at a place designated by the
Secretary of the Corporation.  Notwithstanding the provisions of this Section
7.4, no such special meeting shall be called during a period within 60 days
immediately preceding the date fixed for the next annual meeting of
stockholders.

       7.5.    At any meeting held for the purpose of electing directors at
which the holders of Preferred Stock are entitled to exercise the Special Voting
Right, the presence (in person or by proxy) of the holders of 50% of the then
outstanding shares of the Preferred Stock shall be required and shall be
sufficient to constitute a quorum of such class for the exercise of the Special
Voting Right.

       7.6.    Any director elected by holders of Preferred Stock pursuant to
the exercise of the Special Voting Right shall hold office until the next annual
meeting of stockholders (unless such term has previously terminated pursuant to
Section 7.3 hereof) and any vacancy in respect of any such directorship shall be
filled only by the holders of Preferred Stock by written consent or at a special
meeting called in accordance with the procedures set forth in Section 7.4
hereof, or, if no special meeting is called or written consent executed, at the
next annual meeting of stockholders.

       7.7.    In exercising the Special Voting Right and for all other matters
as to which the holders of shares of Preferred Stock are entitled to vote, each
share of Preferred Stock shall have one vote; provided, however, that any shares
owned beneficially or of record by the Corporation or any of its subsidiaries
shall be deemed to be not outstanding and the holders thereof shall not be
entitled to any vote unless such restriction on such voting right shall be
prohibited by applicable law.

       Section 8.  Ranking.  8.1. All shares of Preferred Stock shall rank
senior, as to payments of dividends and as to distributions of assets (including
any distribution of assets upon any Liquidation), to all shares of Junior Stock,
whether presently outstanding or issued after the date hereof.

       8.2.    All shares of Preferred Stock shall rank on a parity, as to
payments of dividends and as to distributions of assets (including any
distribution of assets upon any Liquidation), with all shares of Parity Stock
issued after the date hereof.

                                     A-ix
<PAGE>
 
       8.3.    As of the date on which this Designation is filed with the
Secretary of State of the State of Delaware, (a) no shares of Prior Stock or
Parity Stock are outstanding and (b) no shares of Junior Stock are outstanding
other than shares of Common Stock.

       Section 9.    Non-Assessability.  The shares of Preferred Stock when
issued, shall be fully-paid and nonassessable.

       Section 10. Preemptive Rights.  The Preferred Stock is not entitled to
any preemptive rights or subscription rights in respect of any Capital Stock.

       Section 11. Registration Books, etc.  The Corporation will keep, or cause
to be kept, at its principal office (or at the office of its agent for such
purpose) proper books in which the names and addresses of the holders of shares
of Preferred Stock issued by the Corporation shall be registered and in which
transfers of such shares may be registered.  The Corporation may treat the
registered holder of any shares of Preferred Stock as the absolute owner thereof
for the purpose of receiving all dividends and redemption payments thereon and
for all other purposes, and the Corporation shall not be affected by any notice
or knowledge to the contrary.

       Section 12. No Consent for Certain Actions.  Anything herein to the
contrary notwithstanding, no consent, approval or vote of the holders of
Preferred Stock shall be required for (a) the creation of any indebtedness of
any kind of the Corporation, (b) the creation of any class of Junior Stock or
Parity Stock, (c) the issuance of shares of Junior Stock or Parity Stock or (d)
any increase or decrease in the amount of authorized Junior Stock or Parity
Stock or any increase, decrease or change in the par value thereof.

       Section 13. Amendments and Waivers.  This Designation of Rights may not
be amended nor may compliance with any of the provisions of this Designation of
Rights be waived without, in each instance, the affirmative vote (at a meeting)
or the written consent (with or without a meeting) of the holders of all the
shares of Preferred Stock then outstanding.

       Section 14. Severability of Provisions.  Whenever possible, each
provision hereof shall be interpreted in a manner as to be effective and valid
under applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof.  If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

       Section 15. Certifications.  On or before June 30 and December 31 of each
year, the Corporation shall provide the Holders with a report, certified by an
officer of the Corporation, setting forth (a) the number of shares of Junior
Stock purchased during the immediately preceding 12-month period pursuant to
Section 6.4(b)(i) (including the dates of purchase and the consideration paid by
the Corporation with respect to each such purchase) and (b) the number of shares
of Junior Stock 

                                      A-x
<PAGE>
 
so purchased by the Corporation which have been resold by the Corporation during
such 12-month period (including the dates of sale and the consideration received
by the Corporation with respect to each such sale).

       Section 16. Notices.  Any notice required to be given hereunder shall be
sufficient if in writing, sent by courier service (with proof of service), hand
delivery or certified or registered mail (return receipt requested and first-
class postage prepaid), and addressed (a) if to any record holder of shares of
Preferred Stock, to the address of such record holder as reflected in the
transfer records for shares of Preferred Stock maintained by the Corporation or
any transfer agent, or (b) if to the Corporation, at its principal executive
offices to the attention of its Secretary.  Any notice given in accordance with
this provision by the Corporation shall be deemed delivered as of the date
receipt or proof of service or delivery is confirmed or on the third Business
Day after the date mailed.

shares of Preferred Stock owned by such holder (such amounts with respect to all
shares of Preferred Stock, in the aggregate, the "Liquidation Amount").  If,
upon any Liquidation, the assets (or proceeds thereof) distributable among the
holders of Preferred Stock are insufficient to pay the Liquidation Amount in
full, then such assets (or the proceeds thereof) shall be distributable among
such holders ratably in accordance with the respective amounts which would be
payable on such shares if all amounts payable thereon were payable in full.

deemed to be a Liquidation, unless such sale, conveyance, exchange or transfer
shall be in connection with a plan of liquidation, dissolution or winding up of
the Corporation.

       4.3 After the payment in cash to the holders of Preferred Stock of the
full amount of the Liquidation Amount with respect to all outstanding shares of
Preferred Stock, the holders of outstanding shares of Preferred Stock shall have
no right or claim, based solely on their ownership of shares of Preferred Stock,
to any of the remaining assets of the Corporation.

       4.4 In the event the assets of the Corporation available for distribution
to the holders of shares of Preferred Stock upon any Liquidation shall be
insufficient to pay the Liquidation Amount in full, no such distribution shall
be made on account of any shares of any Parity Stock upon such Liquidation
unless proportionate distributive amounts shall be paid on account of all shares
of the Preferred Stock, ratably, according to the respective amounts which would
be payable on the 

                                     A-ix

Stock which it has elected to redeem, pro rata, among all holders of Preferred
Stock.

option, elect to have the Corporation redeem all or any number of shares of
Preferred Stock held by such holder, such election to be made by providing
written notice of such election and the number of shares of Preferred Stock
elected to be redeemed to the Corporation (a "Change of Control Redemption
Election") not less than 5 business days prior to the Redemption Date.

       (d) Subject to Section 5.4, the Corporation shall, on the Redemption
Date, redeem the shares of Preferred Stock elected to be redeemed pursuant to
each timely delivered Change of Control Redemption Election and pay the holder
of such shares the Redemption Price therefor, provided that the Corporation has
sufficient legally available funds for such purpose (taking into effect any
obligation of the Corporation to the holders of any Parity Stock related to such
redemption).  Notwithstanding the foregoing, in lieu of the Corporation's making
such purchase, the Corporation may designate a third party to purchase all
shares of Preferred Stock at the same price, payable in cash, and terms and
subject to conditions and procedures no less favorable to the holders of
Preferred Stock than those set forth above in this Section 5.3; provided,
however, that the Corporation shall be liable for, and shall redeem the shares
of Preferred Stock as set forth in this Section 5.3 upon, any default by such
third party to consummate such offer.

       5.4 In the event that the Corporation is required to redeem any shares of
Preferred Stock pursuant to Section 5.1 or Section 5.3 above and does not have
sufficient funds legally available to redeem all of such shares (taking into
effect any obligation of the Corporation to the holders of any Parity Stock
related to such redemption), it shall use all of the funds that it does have
available for such purpose, if any, to redeem such number of shares of Preferred
Stock as is possible with such funds, pro rata, among all holders of Preferred
Stock which have previously provided the Corporation with a Holder Redemption
Notice or a timely Change of Control Redemption Election, as applicable, and for
which all or any portion of the shares of Preferred Stock elected to be redeemed
thereunder have not been redeemed (taking into effect any obligation of the
Corporation to the holders of any Parity Stock related to such redemption).  Any
shares of Preferred Stock which are not redeemed because the Corporation does
not have sufficient funds shall remain outstanding and the holders thereof shall
continue to be entitled to all rights and benefits of holders of Preferred Stock
under this Designation of Rights.

       5.5 The Corporation shall, from time to time, redeem shares of Preferred
Stock to the extent required pursuant to Section 6.2.

       5.6 Upon any redemption of shares of Preferred Stock, the shares of
Preferred Stock so redeemed shall have the status of authorized and unissued
shares of preferred stock of the Corporation, unclassified as to series, and the
number of shares of preferred stock which the 

                                     A-xi
<PAGE>
 
Corporation shall have authority to issue shall not be decreased by the
redemption of such shares of Preferred Stock.

       Section 6.  Certain Restrictions.  6.1  So long as the Corporation shall
be in default of any obligation to make any redemption pursuant to Section 5
hereof and, so long as any Additional Shares are outstanding or any accrued
dividends on the Preferred Stock are unpaid, the Corporation shall not, directly
or indirectly, (a) declare, pay or set apart for payment any dividend or
distribution on or with respect to any Parity Stock other than in shares of
Junior Stock or in Parity Stock of the same class or series or (b) declare, pay
or set apart for payment any dividend or distribution on or with respect to any
Junior Stock other than solely in shares of Junior Stock.

       6.2 So long as any shares of Preferred Stock remain outstanding, the
Corporation shall not, directly or indirectly:

       (a) issue any additional shares of Preferred Stock (other than Additional
   Shares) or any shares of Prior Stock (including as a dividend or distribution
   on any securities);

       (b) (i) redeem, purchase or otherwise acquire or retire for value any
   Junior Stock or (ii) redeem, defease, purchase or otherwise acquire or retire
   for value (whether or not prior to scheduled maturity or scheduled sinking
   fund payment) any mandatory redemption, sinking fund or analogous obligation
   in respect of Junior Stock;

       (c) (i) redeem, purchase or otherwise acquire or retire for value any
   Parity Stock unless a proportionate number of shares of Preferred Stock,
   rounded to the nearest whole share, are redeemed, purchased or otherwise
   acquired or retired for value, ratably, according to the respective amounts
   which would have been payable on the Preferred Stock and such Parity Stock
   upon a Liquidation if all amounts payable thereon were paid in full or (ii)
   redeem, defease, purchase or otherwise acquire or retire for value (whether
   or not prior to scheduled maturity or scheduled sinking fund payment) any
   mandatory redemption, sinking fund or analogous obligation in respect of
   Parity Stock unless proportionate amounts shall be paid on account of all
   shares of the Preferred Stock, ratably, according to the respective amounts
   which would be payable on the Preferred Stock and such Parity Stock upon a
   Liquidation if all amounts payable thereon were paid in full;

       (d) reclassify (by merger, consolidation or otherwise) any Junior Stock
   or Parity Stock as Prior Stock;

       (e) merge into or consolidate with any entity where the surviving or
   continuing corporation will have any outstanding Prior Stock other than
   capital stock corresponding to shares of Prior Stock of the Corporation
   issued before any agreement for such merger or consolidation; or

       (f) amend, alter or repeal by merger or otherwise any of the provisions
   of this Designation of Rights, the Certificate of Incorporation or the By-
   laws of the Corporation so as in any such case to adversely affect the voting
   powers, designations, preferences and 

                                     A-xii
<PAGE>
 
   relative, participating, optional or other special rights, and
   qualifications, limitations or restrictions of the shares of Preferred Stock,
   except as permitted in the Stock Purchase Agreement;

provided, however, that nothing contained in this Designation shall be deemed or
construed to prohibit or restrict the right or ability of any employee stock
ownership plan of the Corporation or any of its Subsidiaries to purchase or
otherwise acquire any shares of Junior Stock or any loan or other extension of
credit by the Corporation or any of its Subsidiaries to any such employee stock
ownership plan.

       6.3 Notwithstanding anything to the contrary contained in this Section 6,
(a) at any time during which the Corporation is then in default of any
obligation to make any redemption pursuant to Section 5 hereof, the Corporation
may nevertheless, directly or indirectly, purchase shares of Junior Stock
covered by any employee stock ownership plan of the Corporation or any of its
Subsidiaries existing on December 23, 1996 (the "ESOP") or a successor plan (i)
to the extent required by those provisions of the ESOP or any successor plan
that are no more favorable to the employees of the Corporation than the
provisions of the ESOP (a "Successor Plan") and (ii) to the extent required by
law, and (b) at any time during which the Corporation is not in default of any
obligation to make any redemption pursuant to Section 5 hereof, the Corporation
may, directly or indirectly, purchase:

         (i) shares of Junior Stock from employees of the Corporation or any of
   its Subsidiaries, former employees of the Corporation or any of its
   Subsidiaries or the estates of deceased employees of the Corporation or any
   of its Subsidiaries, or any party to the Stockholders Agreement of the
   Corporation dated August 21, 1996 (or his or its successors or permitted
   assigns) with an aggregate consideration paid by the Corporation in any
   fiscal year of the Corporation of less than or equal to $5,000,000; provided,
   however, that to the extent that the Corporation fails to resell any such
   shares of Junior Stock within one year after the date of purchase for
   consideration greater than or equal to the consideration paid by the
   Corporation for such shares, the Corporation shall, on the first anniversary
   of the purchase of such shares, redeem a number of shares of Preferred Stock,
   rounded to the nearest whole number, having an aggregate Redemption Price
   equal to the consideration paid by the Corporation for such shares of Junior
   Stock, if such shares have not been sold within such one year period, or the
   excess of the purchase price for such shares over the price for which such
   shares were resold, as applicable;

         (ii) shares of Junior Stock from employees of the Corporation or any of
   its Subsidiaries, former employees of the Corporation or any of its
   Subsidiaries or the estates of deceased employees of the Corporation or any
   of its Subsidiaries; provided, however, that, if at any time the aggregate
   consideration paid by the Corporation, directly or indirectly, for the
   purchase of such shares of Junior Stock pursuant to this clause (ii) exceeds
   $1,000,000 in any fiscal year of the Corporation, the Corporation shall
   concurrently redeem a number of shares of Preferred Stock rounded to the
   nearest whole number, with a Liquidation Value equal to the amount of such
   excess; and

                                    A-xiii
<PAGE>
 
         (iii)  shares of Junior Stock covered by the ESOP or any Successor Plan
   (1) to the extent required by the provisions thereof or (2) to the extent
   required by law.

       Section 7.  Voting.  7.1  The holders of shares of Preferred Stock shall
have no voting rights whatsoever, except for any voting rights to which such
holders may be entitled under applicable laws and except for the voting rights
set forth in the following provisions of this Section 7.

       7.2 Voting Right.  Upon the occurrence and during the continuance of an
Event of Non-Compliance specified in clause (i) of the definition thereof, the
number of directors constituting the Board shall without further act be
increased by one and the holders of shares of the Preferred Stock shall have the
exclusive right (the "Special Voting Right"), voting separately as a class, to
elect one director of the Corporation.

       7.3 The Special Voting Right may be exercised initially either by written
consent or at a special meeting of the holders of the Preferred Stock, called as
hereinafter provided, or at any annual meeting of stockholders held for the
purpose of electing directors, and thereafter at each such annual meeting until
such time as such Event of Non-Compliance shall have been cured in full, (i) in
the case of an Event of Non-Compliance under clause (i)(a) of the definition
thereof, by the declaration and payment or accrual or compounding of the
relevant dividends in cash or in Additional Shares, or (ii) in the case of an
Event of Non-Compliance under clause (i)(b) of the definition thereof, by the
declaration and payment of the relevant dividends in cash or in Additional
Shares, at which time the Special Voting Right and the term of the director
elected pursuant to the exercise of the Special Voting Right shall automatically
terminate.  Upon termination of the Special Voting Right, the number of
directors constituting the Board shall, without further action, be reduced by
one, subject always to increase as provided above upon revesting of the Special
Voting Right.

       7.4 At any time when the Special Voting Right shall have vested and if
the Special Voting Right shall not already have been exercised by written
consent, a proper officer of the Corporation may call, and, upon the written
request, addressed to the Secretary of the Corporation, of the record holders of
shares representing 25% of the then outstanding shares of Preferred Stock, shall
call, a special meeting of the holders of Preferred Stock.  Such meeting shall
be held at the earliest practicable date upon the notice required for annual
meetings of stockholders at the place for holding annual matings of stockholders
of the Corporation or, if none, at a place designated by the Secretary of the
Corporation.  Notwithstanding the provisions of this Section 7.4, no such
special meeting shall be called during a period within 60 days immediately
preceding the date fixed for the next annual meeting of stockholders.

       7.5 At any meeting held for the purpose of electing directors at which
the holders of Preferred Stock are entitled to exercise the Special Voting
Right, the presence (in person or by proxy) of the holders of 50% of the then
outstanding shares of the Preferred Stock shall be required and shall be
sufficient to constitute a quorum of such class for the exercise of the Special
Voting Right.

                                     A-xiv
<PAGE>
 
       7.6 Any director elected by holders of Preferred Stock pursuant to the
exercise of the Special Voting Right shall hold office until the next annual
meeting of stockholders (unless such term has previously terminated pursuant to
Section 7.3 hereof) and any vacancy in respect of any such directorship shall be
filled only by the holders of Preferred Stock by written consent or at a special
meeting called in accordance with the procedures set forth in Section 7.4
hereof, or, if no special meeting is called or written consent executed, at the
next annual meeting of stockholders.

       7.7 In exercising the Special Voting Right and for all other matters as
to which the holders of shares of Preferred Stock are entitled to vote, each
share of Preferred Stock shall have one vote; provided, however, that any shares
owned beneficially or of record by the Corporation or any of its Subsidiaries
shall be deemed to be not outstanding and the holders thereof shall not be
entitled to any vote unless such restriction on such voting right shall be
prohibited by applicable law.

       8.  Ranking  8.1  All shares of Preferred Stock shall rank senior, as to
payments of dividends and as to distributions of assets (including any
distribution of assets upon any Liquidation), to all shares of Junior Stock,
whether presently outstanding or issued after the date hereof.

       8.2 All shares of Preferred Stock shall rank on a parity, as to payments
of dividends and as to distributions of assets (including any distribution of
assets upon any Liquidation), with all shares of Series A Preferred Stock, and
with all Parity Stock issued after the date hereof.

       8.3 As of the date on which this Designation of Rights is filed with the
Secretary of State of the State of Delaware, (a) no shares of Prior Stock are
outstanding and (b) no shares of Junior Stock are outstanding other than shares
of Common Stock.

       Section 9.  Nonassessibility.  The shares of Preferred stock when issued,
shall by fully-paid and nonassessable.

       Section 10. Preemptive Rights.  The Preferred Stock is not entitled to
any preemptive rights or subscription rights in respect of any Capital Stock.

       Section 11. Registration Books, etc..  The Corporation will keep, or
cause to be kept, at its principal office (or at the office of its agent for
such purpose) proper books in which the names and addresses of the holders of
shares of Preferred Stock issued by the Corporation shall be registered and in
which transfers of such shares may be registered.  The Corporation may treat the
registered holder of any shares of Preferred Stock as the absolute owner thereof
for the purpose of receiving all dividends and redemption payments thereon and
for all other purposes, and the Corporation shall not be affected by any notice
or knowledge to the contrary.

       Section 12. No Consent for Certain Actions.  Anything herein to the
contrary notwithstanding, no consent, approval or vote of the holders of
Preferred Stock shall be required for (i) the creation of any indebtedness of
any kind of the Corporation, (ii) the creation of any class of 

                                     A-xv
<PAGE>
 
Junior Stock or Parity Stock, (iii) the issuance of shares of Junior Stock or
Parity Stock or (iv) any increase, decrease or change in the par value thereof.

       Section 13. Amendments and Waivers.  This Designation of Rights may not
be amended nor may compliance with any of the provisions of this Designation of
Rights be waived without, in each instance, the affirmative vote (at a meeting)
or the written consent (with or without a meeting) of the holders of two-thirds
of the shares of Preferred Stock then outstanding.

       Section 14. Severability of Provisions.  Whenever possible, each
provision hereof shall be interpreted in a manner as to be effective and valid
under applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof.  If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

       Section 15. Certifications.  On or before June 30 and December 31 of each
year, the Corporation shall provide the Holders with a report, certified by an
officer of the Corporation, setting forth (i) the number of shares of Junior
Stock purchased during the immediately preceding 12-month period pursuant to
Section 6.4(b)(i) (including the dates of purchase and the consideration paid by
the Corporation with respect to each such purchase) and (ii) the number of
shares of Junior Stock so purchased by the Corporation which have been resold by
the Corporation during such 12-month period (including the dates of sale and the
consideration received by the Corporation with respect to each such sale).

       Section 16. Notices.  Any notice required to be given hereunder shall be
sufficient if in writing, sent by courier service (with proof of service), hand
delivery or certified or registered mail (return receipt requested and first-
class postage prepaid), and addressed (i) if to any record holder of shares of
Preferred Stock, to the address of such record holder as reflected in the
transfer records for shares of Preferred Stock maintained by the Corporation or
any transfer agent, or (ii) if to the Corporation, at its principal executive
offices to the attention of its Secretary.  Any notice given in accordance with
this provision by the Corporation shall be deemed delivered as of the date
receipt or proof of service or delivery is confirmed or when such notice is
returned as undeliverable.

                           ORIGINAL ISSUE OF WARRANTS

          Section II.1. Issuance of Warrants; Form of Warrant Certificates. The
Warrants shall be issued in connection with the issuance of the Series B
Preferred Stock and shall at all times be separately transferable from the
Series B Preferred Stock. Certificates representing the Warrants (the "Warrant
Certificates") shall be issued in registered form only, shall be substantially
in the form attached hereto as Exhibit A, shall be dated the date on which
countersigned by the Warrant Agent and shall have such insertions as are
appropriate or required or permitted by this Agreement and may have such
letters, numbers or other marks of identification and such legends and
endorsements stamped, printed, lithographed or engraved thereon as Holdings may
deem appropriate and as are not inconsistent with the provisions of this
Agreement, or as may be required to comply with any applicable law, rule or
regulation, or to conform to usage. The definitive Warrant Certificates shall be
typed, printed, lithographed or engraved or produced by any combination of these
methods or may be produced in any other manner permitted by applicable law,
rules and regulations, all as determined by the officers executing such Warrant
Certificates, as evidenced by their execution of such Warrant Certificates.

          Section II.2.  Legends.  Each Warrant shall bear the following legend:

     THE COMMON STOCK, PAR VALUE $.01 PER SHARE, OF HOLDINGS (THE "COMMON
     STOCK") FOR WHICH THIS WARRANT IS EXERCISABLE MAY NOT BE OFFERED OR SOLD IN
     THE UNITED STATES ABSENT REGISTRATION UNDER THE SECURITIES AND EXCHANGE ACT
     OF 1933, AS AMENDED (THE "SECURITIES ACT") AND ANY APPLICABLE STATE
     SECURITIES LAWS OR AN APPLICABLE EXEMPTION FROM SUCH REGISTRATION
     REQUIREMENTS.  ACCORDINGLY, NO HOLDER SHALL BE ENTITLED TO EXERCISE SUCH
     HOLDER'S WARRANTS AT ANY TIME UNLESS, AT THE TIME OF EXERCISE, (i) A
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT RELATING TO THE SHARES OF
     COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS WARRANT HAS BEEN FILED
     WITH, AND DECLARED EFFECTIVE BY, THE SECURITIES AND EXCHANGE COMMISSION
     (THE "COMMISSION"), AND NO STOP ORDER SUSPENDING THE EFFECTIVENESS OF SUCH
     REGISTRATION STATEMENT HAS BEEN ISSUED BY THE COMMISSION, OR (ii) THE
     ISSUANCE OF SUCH SHARES IS PERMITTED PURSUANT TO AN EXEMPTION FROM THE
     REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ANY APPLICABLE STATE
     SECURITIES LAWS.

          Section II.3. Execution and Delivery of Warrant Certificates. Warrant
Certificates evidencing Warrants to purchase initially an aggregate of up to
201,048 shares of Common Stock may be executed, on or after the date of this
Agreement, by Holdings and delivered to the Warrant Agent for countersignature,
and the Warrant Agent shall thereupon countersign and deliver such Warrant
Certificates, at the expense of Holdings, upon the written order and at the
direction of Holdings to the purchasers thereof on the date of issuance. The
Warrant Agent is hereby authorized to countersign and deliver Warrant
Certificates as required by this Section 2.3 or

                                       3
<PAGE>
 
by Section 2.4, Section 3.3, Section 3.4 or Article V hereof.

          The Warrant Certificates shall be executed on behalf of Holdings by
its Chairman of the Board, Chief Executive Officer or President or by a Vice
President, either manually or by facsimile signature printed thereon.  The
Warrant Certificates shall be countersigned by manual or facsimile signature of
the Warrant Agent and shall not be valid for any purpose unless so
countersigned.  In case any officer of Holdings whose signature shall have been
placed upon any of the Warrant Certificates shall cease to be an officer of
Holdings before countersignature by the Warrant Agent and the issuance and
delivery thereof, such Warrant Certificates may, nevertheless, be countersigned
by the Warrant Agent and issued and delivered with the same force and effect as
though such person had not ceased to be such officer of Holdings.

          Section II.4.  Transfer and Exchange.  Holdings shall cause to be kept
at the office of the Warrant Agent a register in which, subject to such
reasonable regulations as it may prescribe, Holdings shall provide for the
registration of Warrant Certificates and transfers and exchanges of Warrant
Certificates as provided in this Agreement.

          A Holder may transfer its Warrants only by written application to the
Warrant Agent stating the name of the proposed Transferee and otherwise
complying with the terms of this Agreement.  No such transfer shall be effected
until, and such Transferee shall succeed to the rights of a Holder only upon,
final acceptance and registration of the transfer by the Warrant Agent in the
register in accordance with this Agreement.  Prior to the registration of any
transfer of Warrants by a Holder as provided herein, Holdings, the Warrant Agent
and any agent of Holdings may treat the person in whose name the Warrants are
registered as the owner thereof for all purposes and as the person entitled to
exercise the rights represented thereby, any notice to the contrary
notwithstanding.  When Warrants are presented to the Warrant Agent with a
request to register the transfer thereof or to exchange them for an equal number
of Warrants of other authorized denominations, the Warrant Agent shall register
the transfer or make the exchange as requested if the requirements of this
Agreement for such transaction are met.  To permit registrations of transfers
and exchanges, Holdings shall execute Warrant Certificates at the Warrant
Agent's request.  No service charge shall be made for any registration of
transfer or exchange of Warrants, but Holdings may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection with any registration of transfer of Warrants.

          All Warrant Certificates issued upon any registration of transfer or
exchange of Warrants shall be the valid obligations of Holdings, evidencing the
same obligations, and entitled to the same benefits under this Agreement, as the
Warrant Certificates surrendered for registration of transfer or exchange.

          Section II.5.  Surrender of Warrant Certificates.  Any Warrant
Certificate surrendered for registration of transfer, exchange or exercise of
the Warrants represented thereby shall, if surrendered to Holdings, be delivered
to the Warrant Agent, and all Warrant Certificates surrendered or so delivered
to the Warrant Agent shall be promptly cancelled by the Warrant Agent
and shall not be reissued by Holdings and, except as provided in this Article II
in case of an exchange, Article III hereof in case of the exercise of less than
all the Warrants represented thereby or Article V in case of a mutilated Warrant
Certificate, no Warrant Certificate shall be issued hereunder in lieu thereof.
The Warrant Agent shall destroy all cancelled Warrant Certificates in accordance
with its normal procedures.

                                  ARTICLE III

                      EXERCISE PRICE; EXERCISE OF WARRANTS

          Section III.1.  Exercise Price.  Each Warrant Certificate shall, when
countersigned by the Warrant Agent, entitle the Holder thereof, subject to the
provisions of this Agreement, to purchase one share of Common Stock (subject to
adjustment as provided herein) for each Warrant represented thereby at a
purchase price (the "Exercise Price") of $.01 per share; provided that, at the
option of the Holder thereof, payment of the Exercise Price may be satisfied
through the delivery and cancellation of additional Warrants having an aggregate
Spread equal to the aggregate Exercise Price of the Warrants being exercised.
The calculation of the Spread and the number of Warrants deliverable in payment
of the Exercise Price shall be verified by Holdings.

          Section III.2.  Exercise; Restrictions on Exercise.  (a)  At any time
commencing on the date hereof and on or before the Expiration Date, any
outstanding Warrants may be exercised on any Business Day; provided that the
Registration Statement is, at the time of exercise, effective and available or
the exercise of such Warrants is exempt from the registration requirements of
the Securities Act.  Any Warrants not exercised by 5:00 p.m., New York City
time, on the Expiration Date shall expire and all rights of the Holders of such
Warrants shall terminate.  Additionally, pursuant to Section 4.1(h)(B) hereof,
the Warrants may expire and all rights of the Holders of such Warrants shall
terminate in the event Holdings merges or consolidates with or sells all or
substantially all of its property and assets to a Person if the consideration
payable to holders of Common Stock in exchange for their Common Stock in
connection with such merger, consolidation or sale consists solely of cash or in
the event of the dissolution, liquidation or winding up of Holdings.

          (b) Holdings shall give notice not less than 90 and not more than 120
days prior to the Expiration Date to the Holders of all then outstanding
Warrants to the effect that the Warrants will terminate and become void as of
5:00 p.m., New York City time, on the Expiration Date; provided, however, that
the failure by Holdings to give such notice as provided in this Section shall
not affect such termination and becoming void of the Warrants as of 5:00 p.m.,
New York City time, on the Expiration Date.
 
          (c) In the event a Holder exercises its Warrants at a time when the
Registration Statement is not effective and available, such Holder must furnish
to the Warrant Agent and Holdings such certifications, legal opinions or other
information as either of them may reasonably require to confirm that such
exercise is being made pursuant to an exemption from the registration
requirements of the Securities Act.

          Section III.3. Method of Exercise; Payment of Exercise Price. In
order to exercise all or any of the Warrants represented by a Warrant
Certificate, the Holder thereof must surrender for exercise the Warrant
Certificate to the Warrant Agent at its corporate trust office set forth in
Section 9.5 hereof, with the Subscription Form set forth in the Warrant
Certificate duly executed, together with payment in full of the Exercise Price
then in effect for each share of Common Stock or other securities or property
issuable upon exercise of the Warrants as to which a Warrant is exercised; such
payment may be made (x) by wire transfer or by certified or official bank or
bank cashier's check payable to the order of Holdings or (y) as permitted
pursuant to the proviso in Section 3.1. The Warrant Agent shall promptly notify
Holdings in writing upon the exercise of any Warrant and of the number of shares
of Common Stock delivered upon the exercise of such Warrant; all payments
received upon exercise of Warrants shall be delivered to Holdings by the Warrant
Agent as instructed in writing by Holdings. If less than all the Warrants
represented by

                                       5
<PAGE>
 
a Warrant Certificate are exercised, such Warrant Certificate
shall be surrendered and a new Warrant Certificate of the same tenor and for the
number of Warrants which were not exercised shall be executed by Holdings and
delivered to the Warrant Agent and the Warrant Agent shall countersign the new
Warrant Certificate, registered in such name or names as may be directed in
writing by the Holder, and shall deliver the new Warrant Certificate to the
Person or Persons entitled to receive the same.  Upon exercise of any Warrants
following surrender of a Warrant Certificate in conformity with the foregoing
provisions, the Warrant Agent shall instruct Holdings to transfer promptly to or
upon the written order of the Holder of such Warrant Certificate appropriate
evidence of ownership of any Common Stock or other securities or property
(including money) to which it is entitled, registered or otherwise placed in
such name or names as may be directed in writing by the Holder, and to deliver
such evidence of ownership and any other securities or property (including
money) to the Person or Persons entitled to receive the same, together with an
amount in cash in lieu of any fractional shares as provided in Section 4.5
hereof; provided that the Holder of such Warrant shall be responsible for the
payment of any transfer taxes or other governmental charges imposed as the
result of any change in ownership of such Warrants or the issuance of such
Common Stock or other securities or Warrants other than to the registered owner
of such Warrants.  Upon exercise of a Warrant or Warrants, the Warrant Agent is
hereby authorized and directed to requisition from any transfer agent of the
Common Stock (and all such transfer agents are hereby irrevocably authorized to
comply with all such requests) certificates (bearing the legend set forth in
Section 9.11, if applicable) for the necessary number of shares to which the
Holder of the Warrant or Warrants may be entitled.  A Warrant shall be deemed to
have been exercised immediately prior to the close of business on the date of
the surrender for exercise, as provided above, of the Warrant Certificate
representing such Warrant and, for all purposes of this Agreement, the Person
entitled to receive any Common Stock or other securities or property deliverable
upon such exercise shall, as between such Person and Holdings, be deemed to be
the Holder of such Common Stock or other securities or property of record as of
the close of business on such date and shall be entitled to receive, and the
Warrant Agent shall deliver, at the expense of Holdings, to such Person, any
money, Common Stock or other securities or property to which he would have been
entitled had he been a record holder on such date.

                                   ARTICLE IV

                                  ADJUSTMENTS

          Section IV.1.  Adjustments.  The number of shares of Common Stock
issuable upon exercise of each Warrant shall be subject to adjustment from time
to time as follows:

          (a) Stock Dividends; Stock Splits; Reverse Stock Splits;
Reclassifications.  In case Holdings shall (i) pay a dividend or make any other
distribution with respect to its Common Stock in shares of any class or series
of its capital stock, (ii) subdivide its outstanding Common Stock, (iii) combine
its outstanding Common Stock into a smaller number of shares or (iv) issue any
shares of its capital stock in a reclassification of the Common Stock (other
than a reclassification in connection with a merger, consolidation or other
business combination which will be governed by Section 4.1(h)), the number of
shares of Common Stock purchasable upon exercise of each Warrant immediately
prior to the record date for such dividend or distribution or the effective date
of such subdivision, combination or reclassification shall be adjusted so that
the Holder of each Warrant shall be entitled to receive the kind and number of
shares of Common Stock or other securities of Holdings which such Holder would
have been entitled to receive after the happening of any of the events described
above had such Warrant been exercised immediately prior to the happening of such
event or any record date with respect thereto (with any record date

                                       6
<PAGE>
 
requirement being deemed to have been satisfied). An adjustment made pursuant to
this Section 4.1(a) shall become effective immediately after the effective date
of such event retroactive to the record date, if any, for such event.

          (b) Rights; Options; Warrants.  In case Holdings shall issue rights,
options, warrants or convertible or exchangeable securities (other than a
convertible or exchangeable security subject to Section 4.1(a)) to all holders
of its Common Stock, entitling them to subscribe for or purchase Common Stock at
a price per share of Common Stock (determined in the case of such rights,
options, warrants or convertible or exchangeable securities, by dividing (x) the
total amount receivable by Holdings in consideration of the issuance of such
rights, options, warrants or convertible or exchangeable securities, if any,
plus the total consideration payable to Holdings upon exercise, conversion or
exchange thereof, by (y) the total number of shares of Common Stock covered by
such rights, options, warrants or convertible or exchangeable securities) which
is lower (at the record date for such issuance) than the then Current Market
Value per share of Common Stock, the number of shares of Common Stock thereafter
purchasable upon exercise of each Warrant shall be determined by multiplying the
number of shares of Common Stock theretofore purchasable upon exercise of each
Warrant by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to the issuance of such rights,
options, warrants or convertible or exchangeable securities plus the number of
additional shares of Common Stock offered for subscription or purchase or
issuable upon conversion or exchange, and the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to the issuance
of such rights, options, warrants or convertible or exchangeable securities plus
the number of shares which the aggregate offering price of the total number of
shares of Common Stock so offered would purchase at the then Current Market
Value per share of Common Stock.  Such adjustment shall be made whenever such
rights, options, warrants or convertible or exchangeable securities are issued,
and shall become effective retroactively immediately after the record date for
the determination of shareholders entitled to receive such rights, options,
warrants or convertible or exchangeable securities.

          (c) Issuance of Common Stock at Lower Values.  In case Holdings shall
sell or issue any shares of Common Stock or Right (excluding (i) any Right
issued in any of the transactions described in Section 4.1(a) or (b) above, (ii)
any shares of Common Stock issued pursuant to (x) any Rights outstanding on the
date of this Agreement, (y) a Right, if on the date such Right was issued, the
exercise, conversion or exchange price per share of Common Stock with respect
thereto was at least equal to the Current Market Value per share of Common Stock
on such date and (z) Rights (with respect to not more than an aggregate of 5% of
the outstanding shares of Common Stock) issued to employees of Holdings and its
subsidiaries resident in Canada pursuant to Holdings' stock option plan and
(iii) any Right issued as consideration when any corporation or business is
acquired, merged into or becomes part of Holdings or a subsidiary of Holdings in
an arm's-length transaction between Holdings and a Person other than an
Affiliate of Holdings) at a price per share of Common Stock (determined in the
case of such Right, by dividing (x) the total amount receivable by Holdings in
consideration of the sale and issuance of such Right, plus the total
consideration payable to Holdings upon exercise, conversion or exchange thereof,
by (y) the total number of shares of Common Stock covered by such Right) that is
lower than the Current Market Value per share of Common Stock in effect
immediately prior to such sale or issuance, then the number of shares of Common
Stock thereafter purchasable upon the exercise of each Warrant shall be
determined by multiplying the number of shares of Common Stock theretofore
purchasable upon exercise of such Warrant by a fraction, the numerator of which
shall be the number of shares of Common Stock outstanding immediately after such
sale or issuance and the denominator of which shall be the number of shares of
Common Stock outstanding immediately prior to such sale or issuance plus the
number of shares of Common Stock which the aggregate consideration received
(determined as provided below) for such sale

                                       7
<PAGE>
 
or issuance would purchase at such Current Market Value per share of Common
Stock. For purposes of this Section 4.1(c), the shares of Common Stock which the
holder of any such Right shall be entitled to subscribe for or purchase shall be
deemed to be issued and outstanding as of the date of such sale and issuance and
the consideration received by Holdings therefor shall be deemed to be the
consideration received by Holdings for such Right, plus the consideration or
premiums stated in such Right to be paid for the shares of Common Stock covered
thereby. In case Holdings shall sell and issue shares of Common Stock or any
Right, for a consideration consisting, in whole or in part, of property other
than cash or its equivalent, then in determining the "price per share of Common
Stock" and the "consideration received by Holdings" for purposes of the first
sentence of this Section 4.1(c), the Board of Directors of Holdings shall
determine, in good faith, the fair value of said property, which determination
shall be evidenced by a resolution of the Board of Directors of Holdings. In
case Holdings shall sell and issue any Right together with one or more other
securities as part of a unit at a price per unit, then in determining the "price
per share of Common Stock" and the "consideration received by Holdings" for
purposes of the first sentence of this Section 4.1(c), the Board of Directors of
Holdings shall determine, in good faith, the fair value of the Right then being
sold as part of such unit.

          (d) Distributions of Debt, Assets, Subscription Rights or Convertible
Securities.  In case Holdings shall fix a record date for the making of a
distribution to all holders of its Common Stock of evidences of its
indebtedness, assets, cash dividends or distributions (excluding dividends or
distributions referred to in Section 4.1(a) above and excluding distributions in
connection with the dissolution, liquidation or winding up of Holdings which
will be governed by Section 4.1(h)(B) below) or securities (excluding those
referred to in Section 4.1(a), Section 4.1(b) or Section 4.1(c) above), then in
each case the number of shares of Common Stock purchasable after such record
date upon the exercise of each Warrant shall be determined by multiplying the
number of shares of Common Stock purchasable upon the exercise of such Warrant
immediately prior to such record date by a fraction, the numerator of which
shall be the Current Market Value per share of Common Stock immediately prior to
the record date for such distribution and the denominator of which shall be the
Current Market Value per share of Common Stock immediately prior to the record
date for such distribution less the then fair value (as determined in good faith
by the Board of Directors of Holdings) of the portion of the assets, evidence of
indebtedness, cash dividends or distributions or securities so distributed
applicable to one share of Common Stock.  Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the date of
distribution retroactive to the record date for the determination of
shareholders entitled to receive such distribution.

          (e) Expiration of Rights, Options and Conversion Privileges.  Upon the
expiration of any rights, options, warrants or conversion or exchange privileges
that have previously resulted in an adjustment hereunder, if any thereof shall
not have been exercised, the number of shares of Common Stock issuable upon the
exercise of each Warrant shall, upon such expiration, be readjusted and shall
thereafter, upon any future exercise, be such as they would have been had they
been originally adjusted (or had the original adjustment not been required, as
the case may be) as if (i) the only shares of Common Stock so issued were the
shares of Common Stock, if any, actually issued or sold upon the exercise of
such rights, options, warrants or conversion or exchange rights and (ii) such
shares of Common Stock, if any, were issued or sold for the consideration
actually received by Holdings upon such exercise plus the consideration, if any,
actually received by Holdings for issuance, sale or grant of all such rights,
options, warrants or conversion or exchange rights whether or not exercised;
provided, that no such readjustment shall have the effect of

                                       8
<PAGE>
 
decreasing the number of shares issuable upon exercise of each Warrant by a
number, in excess of the amount or number of the adjustment initially made in
respect to the issuance, sale or grant of such rights, options, warrants or
conversion or exchange rights.

          (f) Current Market Value.  For the purposes of any computation
hereunder, the Current Market Value per share of Common Stock or of any other
security (herein collectively referred to as a "security") at any date herein
specified shall be:

          (i)  if the security is not registered under the Exchange Act, the
     value of the security (A) determined in good faith by the Board of
     Directors of Holdings and certified in a board resolution based upon the
     most recently completed arm's-length transaction with respect to such
     security between Holdings and a Person other than an Affiliate of Holdings
     and the closing of which occurs on such date or shall have occurred within
     the six months preceding such date, or (B) if no such transaction shall
     have occurred within such six-month period, most recently determined as of
     a date within the six months preceding such date by an Independent
     Financial Expert selected by Holdings, or (C) if no such determination
     shall have been made within such six-month period or if Holdings so
     chooses, determined as of such date by an Independent Financial Expert
     selected by Holdings, or

          (ii) if the security is registered under the Exchange Act, the average
     of the daily market prices of the security for the 20 consecutive trading
     days immediately preceding such date or, if the security has been
     registered under the Exchange Act for less than 20 consecutive trading days
     before such date, then the average of the daily market prices for all of
     the trading days before such date for which daily market prices are
     available.  The market price for each such trading day shall be:  (A) in
     the case of a security listed or admitted to trading on any national
     securities exchange, the closing sales price, regular way, on such day, or
     if no sale takes place on such day, the average of the closing bid and
     asked prices on such day on the principal national securities exchange on
     which such security is listed or admitted, as determined by the Board of
     Directors of Holdings, in good faith, (B) in the case of a security not
     then listed or admitted to trading on any national securities exchange, the
     last reported sale price on such day, or if no sale takes place on such
     day, the average of the closing bid and asked prices on such day, as
     reported by a reputable quotation source designated by Holdings, (C) in the
     case of a security not then listed or admitted to trading on any national
     securities exchange and as to which no such reported sale price or bid and
     asked prices are available, the average of the reported high bid and low
     asked prices on such day, as reported by a reputable quotation service, or
     a newspaper of general circulation in the Borough of Manhattan, City and
     State of New York customarily published on each Business Day, designated by
     Holdings, or, if there shall be no bid and asked prices on such day, the
     average of the high bid and low asked prices, as so reported, on the most
     recent day (not more than 30 days prior to the date in question) for which
     prices have been so reported and (D) if there are no bid and asked prices
     reported during the 30 days prior to the date in question, the Current
     Market Value of the security shall be determined as if the security were
     not registered under the Exchange Act.

          (g) De Minimis Adjustments. No adjustment in the number of shares of
Common Stock purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one percent (1%) in the number
of shares of Common Stock purchasable upon the exercise of each Warrant;
provided, however, that any adjustments which by reason of this Section 4.1(g)
are not required to be made shall be carried forward and taken into

                                       9
<PAGE>
 
account in any subsequent adjustment. All calculations shall be made to the
nearest one-thousandth of a share.

          (h) Consolidation, Merger, Etc.  (A)  Subject to the provisions of
Subsection (B) below of this Section 4.1(h), in case of the consolidation of
Holdings with, or merger of Holdings with or into, or of the sale of all or
substantially all of the properties and assets of Holdings to, any Person and in
connection therewith consideration is payable to holders of Common Stock (or
other securities or property purchasable upon exercise of Warrants) in exchange
therefor, the Warrants shall remain subject to the terms and conditions set
forth in this Agreement and each Warrant shall, after such consolidation, merger
or sale, entitle the Holder to receive upon exercise the number of shares of
capital stock or other securities or property (including cash) of Holdings, or
of such Person resulting from such consolidation or surviving such merger or to
which such sale shall be made, as the case may be, that would have been
distributable or payable on account of the shares of Common Stock (or other
securities or properties purchasable upon exercise of Warrants) if such Holder's
Warrants had been exercised immediately prior to such merger, consolidation or
sale (or, if applicable, the record date therefor); and in any such case the
provisions of this Agreement with respect to the rights and interests thereafter
of the Holders of Warrants shall be appropriately adjusted by the Board of
Directors of Holdings in good faith so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or any property
thereafter deliverable on the exercise of the Warrants.

          (B)  Notwithstanding the foregoing, (x) if Holdings merges or
consolidates with, or sells all or substantially all of its property and assets
to, another Person and consideration is payable to holders of Common Stock in
exchange for their Common Stock in connection with such merger, consolidation or
sale which consists solely of cash, or (y) in the event of the dissolution,
liquidation or winding up of Holdings, then the Holders of Warrants shall be
entitled to receive distributions on the date of such event on an equal basis
with holders of Common Stock (or other securities issuable upon exercise of the
Warrants) as if the Warrants had been exercised immediately prior to such event,
less the Exercise Price.  Upon receipt of such payment, if any, the right of a
Holder shall terminate and cease and such Holder's Warrants shall expire.  In
case of any such merger, consolidation or sale of assets, the surviving or
acquiring Person and, in the event of any dissolution, liquidation or winding up
of Holdings, Holdings shall deposit promptly with the Warrant Agent the funds,
if any, necessary to pay the Holders of the Warrants.  After receipt of such
deposit from such Person or Holdings and after receipt of surrendered Warrant
Certificates, the Warrant Agent shall make payment by delivering a check in such
amount as is appropriate (or, in the case of consideration other than cash, such
other consideration as is appropriate) to such Person or Persons as it may be
directed in writing by the Holder surrendering such Warrants.

          (i) In addition to the foregoing adjustments, the Board of Directors
of Holdings may make any other adjustment to increase the number of Underlying
Securities issuable upon exercise of Warrants as it may, in good faith, deem
desirable to protect the rights and benefits of Holders.  In addition, Holdings
may from time to time increase the number of Underlying Securities issuable upon
exercise of Warrants, provided that any such increase must be effective for at
least 30 calendar days, and must be preceded by written notice of such increase
to the Holders and the Warrant Agent, which notice must be mailed at least 30
calendar days prior to the effective date of such increase.  Any such increase
shall not alter or adjust the Exercise Price.

          (j) If at any time the Current Market Value of any security is
required in order to comply with the terms of this Agreement, and such Current
Market Value is determined in accordance with Section 4.1(f)(i) hereof: (1) if
clause (A) of Section 4.1(f)(i) is applicable,

                                       10
<PAGE>
 
Holdings shall, as promptly as practicable, deliver to the Warrant Agent a copy
of the board resolution certifying the Current Market Value determination and a
brief description of the arm's-length transaction upon which such determination
was based; (2) if clause (B) of Section 4.1(f)(i) is applicable, Holdings shall
as promptly as practicable deliver to the Warrant Agent the value report of the
Independent Financial Expert, stating the value of the security and briefly
describing the nature and scope of the examination upon which the determination
was made (the "Value Report"); and (3) if clause (C) of Section 4.1(f)(i) is
applicable, Holdings shall cause the Independent Financial Expert to deliver to
Holdings, with a copy to the Warrant Agent, within 45 days of the appointment of
the Independent Financial Expert, a Value Report. The Warrant Agent shall have
no duty with respect to any such board resolution or Value Report, except to
keep it on file and available for inspection by the Holders. The determination
as to value in accordance with the provisions of this Section 4.1(j) shall be
conclusive on all Persons. The Independent Financial Expert shall use one or
more valuation methods that it determines, in its best professional judgment, to
be most appropriate. The Independent Financial Expert shall consult with
management of Holdings in order to allow management to comment on the proposed
value prior to delivery to Holdings of any Value Report of the Independent
Financial Expert pursuant to clause (3) above.

          Section IV.2.  Notice of Adjustment.  Whenever the number of shares of
Common Stock or other stock or property purchasable upon the exercise of each
Warrant is adjusted, as herein provided, Holdings shall cause the Warrant Agent
promptly to mail, at the expense of Holdings, to each Holder notice of such
adjustment or adjustments and shall deliver to the Warrant Agent a certificate
of a firm of independent public accountants selected by the Board of Directors
of Holdings (who may be the regular accountants employed by Holdings) setting
forth the number of shares of Common Stock or other stock or property
purchasable upon the exercise of each Warrant after such adjustment, setting
forth a brief statement of the facts requiring such adjustment and setting forth
the computation by which such adjustment was made.  Such certificate shall be
conclusive evidence of the correctness of such adjustment.  The Warrant Agent
shall be entitled to and shall be fully protected in relying on such certificate
and shall be under no duty or responsibility with respect to any such
certificate, except to exhibit the same, from time to time, to any Holder
desiring an inspection thereof during reasonable business hours.  The Warrant
Agent shall not at any time be under any duty or responsibility to any Holders
to determine whether any facts exist which may require any adjustment of the
Exercise Price or the number of shares of Common Stock or other securities or
property purchasable on exercise of the Warrants, or with respect to the nature
or extent of any such adjustment when made, or with respect to the method
employed in making such adjustment, or the validity or value (or the kind or
amount) of any Common Stock or other securities or property which may be
purchasable on exercise of the Warrants.  The Warrant Agent shall not be deemed
to have knowledge of such adjustment unless and until it shall have received
such certificate.  The Warrant Agent shall not be responsible for any failure of
Holdings to make any cash payment or to issue, transfer or deliver any shares of
Common Stock or other securities or property upon the exercise of any Warrant.

          Section IV.3. Statement on Warrants. Irrespective of any adjustment in
the number or kind of shares purchasable upon the exercise of the Warrants,
Warrants theretofore or thereafter issued may continue to express the same
number and kind of shares as are stated in the Warrants initially issuable
pursuant to this Agreement.

          Section IV.4.  Notice of Consolidation, Merger, Etc.  In case at any
time after the date hereof and prior to 5:00 p.m., New York City time, on the
Expiration Date, there shall be any (i) consolidation or merger involving
Holdings or sale, transfer or other disposition of all or substantially all of
Holdings's property, assets or business (except a merger in which Holdings shall

                                       11
<PAGE>
 
be the surviving corporation and holders of Common Stock (or other securities or
property purchasable upon exercise of the Warrants) receive no consideration in
respect of their shares) or (ii) any other transaction contemplated by Section
4.1(h)(B) above, then in any one or more of such cases, Holdings shall cause to
be mailed to the Warrant Agent and each Holder of a Warrant, at the earliest
practicable time (and, in any event, not less than 20 calendar days before any
date set for definitive action), notice of the date on which such
reorganization, sale, consolidation, merger, dissolution, liquidation or winding
up shall take place, as the case may be.  Such notice shall also set forth such
facts as shall indicate the effect of such action (to the extent such effect may
be known at the date of such notice) on the kind and amount of Common Stock and
other securities, money and other property deliverable upon exercise of the
Warrants.  Such notice shall also specify the date as of which the holders of
record of the Common Stock or other securities or property issuable upon
exercise of the Warrants shall be entitled to exchange their shares for
securities, money or other property deliverable upon such reorganization, sale,
consolidation, merger, dissolution, liquidation or winding up, as the case may
be.

          Section IV.5. Fractional Interests. If more than one Warrant shall be
presented for exercise in full at the same time by the same Holder, the number
of full shares of Common Stock which shall be issuable upon such exercise
thereof shall be computed on the basis of the aggregate number of shares of
Common Stock purchasable on exercise of the Warrants so presented. If any
fraction of a share of Common Stock would, except for the provisions of this
Section 4.5, be issuable on the exercise of any Warrant (or specified portion
thereof), Holdings shall pay an amount in cash calculated by it to be equal to
the then Current Market Value per share of Common Stock multiplied by such
fraction computed to the nearest whole cent.


                                   ARTICLE V

                               LOSS OR MUTILATION

          Upon receipt by Holdings and the Warrant Agent of evidence
satisfactory to them of the ownership and the loss, theft, destruction or
mutilation of any Warrant Certificate and of indemnity in the form of an
indemnity bond satisfactory to them and (in the case of mutilation) upon
surrender and cancellation thereof, then, in the absence of notice to Holdings
or the Warrant Agent that the Warrants  represented thereby have been acquired
by a bona fide purchaser, Holdings shall execute and the Warrant Agent shall
countersign and deliver to the registered Holder of the lost, stolen, destroyed
or mutilated Warrant Certificate, in exchange for or in lieu thereof, a new
Warrant Certificate of the same tenor and for like aggregate number of Warrants.
Upon the issuance of any new Warrant Certificate under this Article V, Holdings
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and other expenses
(including the fees and expenses of the Warrant Agent) in connection therewith.
Every new Warrant Certificate executed and delivered pursuant to this Article V
in lieu of any lost, stolen or destroyed Warrant Certificate shall constitute a
contractual obligation of Holdings, whether or not the allegedly lost, stolen or
destroyed Warrant Certificates shall be at any time enforceable by anyone, and
shall be entitled to the benefits of this Agreement equally and proportionately
with any and all other Warrant Certificates duly executed and delivered
hereunder.  The provisions of this Article V are exclusive and shall preclude
(to the extent lawful) all other rights or remedies with respect to the
replacement of mutilated, lost, stolen, or destroyed Warrant Certificates.

                                   ARTICLE VI

                         AUTHORIZATION AND RESERVATION
                     OF COMMON STOCK; PURCHASE OF WARRANTS

          Section VI.1.  Reservation of Authorized Common Stock.  Holdings shall
at all times reserve and keep available for issue upon the exercise of Warrants
such number of its authorized but unissued shares of Common Stock or other
securities of Holdings deliverable upon exercise of Warrants as will be
sufficient to permit the exercise in full of all outstanding Warrants and will
cause appropriate evidence of ownership of such Common Stock or other securities
of Holdings to be delivered to the Warrant Agent upon its request for delivery
upon the exercise of Warrants, and all such shares of Common Stock will, at all
times, be duly approved for listing subject to official notice of issuance on
each securities exchange, interdealer quotation system or market, if any, on
which such Common Stock is then listed.  Holdings covenants that all Common
Stock or other securities of Holdings that may be issued upon the exercise of
the Warrants will, upon issuance, be duly authorized, validly issued, fully paid
and nonassessable, and free from preemptive rights and all taxes, liens,
charges, encumbrances and security interests.

          Section VI.2.  Purchase of Warrants by Holdings.  Holdings shall have
the right, except as limited by law, other agreement or herein, to purchase or
otherwise acquire Warrants at such times, in such manner and for such
consideration as it may deem appropriate.  In the event Holdings shall purchase
or otherwise acquire Warrants, the related Warrant certificates shall thereupon
be delivered to the Warrant Agent and be cancelled by it and retired.


                              ARTICLE VII

                    WARRANT HOLDERS NOT DEEMED STOCKHOLDERS

          Holdings and the Warrant Agent may deem and treat the registered
Holder(s) of the Warrant Certificates as the absolute owner(s) thereof
(notwithstanding any notation of ownership or other writing thereon made by
anyone), for the purpose of any exercise thereof and for all other purposes, and
neither Holdings nor the Warrant Agent shall be affected by any notice to the
contrary.  Prior to the exercise of the Warrants, no Holder of a Warrant
Certificate, as such, shall be entitled to any rights of a stockholder of
Holdings, including, without limitation, the right to vote or to consent to any
action of the stockholders, to receive dividends or other distributions, to
exercise any preemptive right or to receive any notice of meetings of
stockholders and, except as otherwise provided in this Agreement, shall not be
entitled to receive any notice of any proceedings of Holdings.

                                  ARTICLE VIII

                               THE WARRANT AGENT

          Section VIII.1.  Duties and Liabilities.  The Warrant Agent hereby
accepts the agency established by this Agreement and agrees to perform the
duties and obligations, and no implied duties or obligations shall be read into
this Agreement against Warrant Agent, imposed by this Agreement upon the terms
and conditions herein set forth, by all of which Holdings and the Holders of
Warrants, by their acceptance thereof, shall be bound.

                                       13
<PAGE>
 
          (a) The statements contained herein and in the Warrant Certificate
shall be taken as statements of Holdings, and the Warrant Agent assumes no
responsibility for the correctness of any of the same except as describe the
Warrant Agent or any action taken by it.  The Warrant Agent assumes no
responsibility with respect to the distribution of the Warrants except as herein
otherwise provided.

          (b) The Warrant Agent shall not be responsible for any failure of
Holdings to comply with the covenants contained in this Agreement or in the
Warrants to be complied with by Holdings.

          (c) The Warrant Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty thereunder either itself (through
its employees) or by or through its attorneys or agents (which shall not include
its employees) and shall not be responsible for the misconduct of any agent
appointed.

          (d) Whenever in the performance of its duties under this Agreement the
Warrant Agent shall deem it necessary or desirable that any fact or matter be
proved or established by Holdings prior to taking or suffering any action
hereunder, such fact or matter (unless such evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by the Chairman of the Board, President,
Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, a
Vice President, the Treasurer or Secretary of Holdings and delivered to the
Warrant Agent; and such certificate shall be full authorization to the Warrant
Agent for any action taken or suffered by it under the provisions of this
Agreement in reliance upon such certificate.

          (e) Holdings agrees to pay the Warrant Agent reasonable compensation
for all services rendered by the Warrant Agent in the performance of its duties
under this Agreement, to reimburse the Warrant Agent for all expenses, taxes and
governmental charges and other charges of any kind and nature incurred by the
Warrant Agent (including reasonable fees and expenses of the Warrant Agent's
counsel and agents) in the performance of its duties under this Agreement.
Holdings also agrees to indemnify the Warrant Agent for, and to hold it harmless
against, any loss, liability, or expenses incurred without negligence or willful
misconduct on the part of Warrant Agent, for anything done or omitted by the
Warrant Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability in the premises.  The indemnity provided for herein shall survive the
expiration of the Warrants and termination of this Agreement.  The cost and
expenses incurred in enforcing this right of indemnification shall be paid by
Holdings.  The Warrant Agent may conclusively rely upon and shall be protected
and shall incur no liability for or in respect of any action taken, suffered or
omitted by it in connection with, its administration of this Agreement in
reliance upon any Warrant Certificate or certificate for shares of stock or
other securities of Holdings, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons.

          Notwithstanding anything in the Agreement to the contrary, in no event
shall the Warrant Agent be liable for special indirect, or consequential loss or
damage of any kind whatsoever (including but not limited to lost profits), even
if the Warrant Agent has been advised of the likelihood of such loss or damage
and regardless of the form of the action.

          (f) The Warrant Agent shall be under no obligation to institute any
action, suit 

                                       14
<PAGE>
 
or legal proceeding or to take any other action likely to involve
expense unless Holdings or one or more Holders shall furnish the Warrant Agent
with reasonable security and indemnity satisfactory to the Warrant Agent for any
costs and expenses which may be incurred, but this provision shall not affect
the power of the Warrant Agent to take such action as the Warrant Agent may
consider proper, whether with or without any such security or indemnity.  All
rights of action under this Agreement or under any of the Warrants may be
enforced by the Warrant Agent without the possession of any of the Warrants or
the production thereof at any trial or other proceeding relative thereto, and
any such action, suit or proceeding instituted by the Warrant Agent shall be
brought in its name as Warrant Agent, and any recovery of judgment shall be for
the ratable benefit of the Holders, as their respective rights or interests may
appear.

          (g) The Warrant Agent and any stockholder, director, officer or
employee of the Warrant Agent may buy, sell or deal in any of the Warrants or
other securities of Holdings or become pecuniarily interested in any
transactions in which Holdings may be interested, or contract with or lend money
to Holdings or otherwise act as fully and freely as though it were not Warrant
Agent under this Agreement or such director, officer or employee.  Nothing
herein shall preclude the Warrant Agent from acting in any other or for any
other capacity for Holdings or for any other legal entity including, without
limitation, acting as transfer agent or as a lender to the Company or an
affiliate thereof.

          (h) The Warrant Agent shall act hereunder solely as agent, and its
duties shall be determined solely by the provisions hereof.  The Warrant Agent
shall not be liable for anything which it may do or refrain from doing in
connection with this Agreement except for its own negligence or willful
misconduct.

          (i) The Warrant Agent may conclusively rely upon and shall be
protected by Holdings and shall not incur any liability or responsibility to
Holdings or to any Holder for any action taken in reliance on any notice,
resolution, waiver, consent, order, certificate, or other paper, document or
instrument reasonably believed by it to be genuine and to have been signed, sent
or presented by the proper party or parties.

          (j) The Warrant Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Warrant Agent) or in respect of the validity or
execution of any Warrant (except its counter-signature thereof); nor shall the
Warrant Agent by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any Underlying Securities (or
other stock) to be issued pursuant to this Agreement or any Warrant, or as to
whether any Underlying Securities (or other stock) will, when issued, be validly
issued, fully paid and nonassessable, or as to the Exercise Price or the number
or amount of Underlying Securities or other securities or other property
issuable upon exercise of any Warrant.

          (k) The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, President, Chief Executive Officer, Chief Operating
Officer, Chief Financial Officer, a Vice President or Secretary of Holdings, and
to apply to such officers for advice or instructions in connection with its
duties, and shall not be liable for any action taken or suffered to be taken by
it and without negligence in accordance with instructions of any such officer or
officers.

          Section VIII.2. Right to Consult Counsel. Before the Warrant Agent
acts or refrains from acting, it may at any time consult with legal counsel (who
may be legal counsel for

                                       15
<PAGE>
 
Holdings), and the opinion or advice of such counsel shall be full and complete
authorization and protection to the Warrant Agent and the Warrant Agent shall
incur no liability or responsibility to Holdings or to any Holder for any action
taken, suffered or omitted by it in good faith in accordance with the opinion or
advice of such counsel.

          Section VIII.3. No Restrictions on Actions. The Warrant Agent and any
stockholder, director, officer or employee of the Warrant Agent may buy, sell or
deal in any of the Warrants or other securities of Holdings or become
pecuniarily interested in transactions in which Holdings may be interested, or
contract with or lend money to Holdings or otherwise act as fully and freely as
though it were not the Warrant Agent under this Agreement. Nothing herein shall
preclude the Warrant Agent from acting in any other capacity for Holdings or for
any other legal entity.

          Section VIII.4. Change of Warrant Agent. The Warrant Agent may resign
from its position as such and be discharged from all further duties and
liabilities hereunder (except liability arising as a result of the Warrant
Agent's own negligence or willful misconduct), after giving one month's prior
written notice to Holdings. Holdings may remove the Warrant Agent upon one
month's written notice specifying the date when such discharge shall take
effect, and the Warrant Agent shall thereupon in like manner be discharged from
all further duties and liabilities hereunder, except as aforesaid. Holdings
shall cause to be mailed to each Holder of a Warrant a copy of said notice of
resignation or notice of removal, as the case may be. Upon such designation or
removal Holdings shall appoint in writing a new warrant agent. If Holdings shall
fail to make such appointment within a period of 30 calendar days after it has
been notified in writing of such resignation by the resigning Warrant Agent or
after such removal, then the Holder of any Warrant may apply to any court of
competent jurisdiction for the appointment of a new warrant agent. Pending
appointment of a successor to the original Warrant Agent, either by Holdings or
by such a court, the duties of the Warrant Agent shall be carried out by
Holdings. Any new warrant agent, whether appointed by Holdings or by such a
court, shall be a bank (or subsidiary thereof) or trust company doing business
under the laws of the United States or any state thereof, in good standing and
having a combined capital and surplus of not less than $50,000,000. The combined
capital and surplus of any such new warrant agent shall be deemed to be the
combined capital and surplus as set forth in the most recent annual report of
its condition published by such warrant agent prior to its appointment; provided
that such reports are published at least annually pursuant to law or to the
requirements of a federal or state supervising or examining authority. After
acceptance in writing of such appointment by the new warrant agent, it shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named herein as the Warrant Agent, without any further
assurance, conveyance, act or deed; however, the original Warrant Agent shall in
all events deliver and transfer to the successor Warrant Agent all property, if
any, at the time held hereunder by the original Warrant Agent and if for any
reason it shall be necessary or expedient to execute and deliver any further
assurance, conveyance, act or deed, the same shall be done at the expense of
Holdings and shall be legally and validly executed and delivered by the
resigning or removed Warrant Agent. Not later than the effective date of any
such appointment, Holdings shall file notice thereof with the resigning or
removed Warrant Agent and shall forthwith cause a copy of such notice to be
mailed to each Holder of a Warrant at the cost and expense of Holdings. Failure
to give any notice provided for in this Section 8.5, however, or any defect
therein, shall not affect the legality or validity of the resignation of the
Warrant Agent or the appointment of a new warrant agent, as the case may be.

          Section VIII.5. Successor Warrant Agent. Any corporation into which
the Warrant Agent or any new warrant agent may be merged, or any corporation
resulting from any

                                       16
<PAGE>
 
consolidation to which the Warrant Agent or any new warrant agent shall be a
party, shall be a successor Warrant Agent under this Agreement without any
further act; provided that such corporation would be eligible for appointment as
successor to the Warrant Agent under the provisions of Section 8.5 hereof. Any
such successor Warrant Agent shall promptly cause notice of its succession as
Warrant Agent to be mailed to each Holder of a Warrant .


                                   ARTICLE IX

                                 MISCELLANEOUS

          Section IX.1.  Money Deposited with the Warrant Agent.  The Warrant
Agent shall not be required to pay interest on any moneys deposited pursuant to
the provisions of this Agreement except such as it shall agree in writing with
Holdings to pay thereon.  Any moneys, securities or other property which at any
time shall be deposited by Holdings or on its behalf with the Warrant Agent
pursuant to this Agreement shall be and are hereby assigned, transferred and set
over to the Warrant Agent in trust for the purpose for which such moneys,
securities or other property shall have been deposited; but such moneys,
securities or other property need not be segregated from other funds, securities
or other property except to the extent required by law.


          Section IX.2.  Payment of Taxes.  All Common Stock or other securities
issuable upon the exercise of Warrants shall be validly issued, fully paid and
nonassessable, and Holdings shall pay any taxes and other governmental charges
that may be imposed under the laws of the United States of America or any
political subdivision or taxing authority thereof or therein in respect of the
issue or delivery thereof or of other securities deliverable upon exercise of
Warrants (other than income taxes imposed on the Holders).  Holdings shall not
be required, however, to pay any tax or other charge imposed in connection with
any transfer involved in the issue of any certificate for Common Stock or other
securities or property issuable upon the exercise of the Warrants or payment of
cash to any Person other than the Holder of a Warrant Certificate surrendered
upon the exercise of a Warrant and in case of such transfer or payment, the
Warrant Agent and Holdings shall not be required to issue any stock certificate
or pay any cash until such tax or charge has been paid or it has been
established to the Warrant Agent's and Holdings's satisfaction that no such tax
or charge is due.

          Section IX.3.  Merger, Consolidation or Sale of Assets of Holdings.
Holdings will not merge into or consolidate with any other Person, or sell or
otherwise transfer all or substantially all of its property, assets or business
to a successor of Holdings, unless the Person resulting from such merger or
consolidation, or such successor of Holdings, shall expressly assume, by
supplemental agreement satisfactory in form to the Warrant Agent and executed
and delivered to the Warrant Agent, the due and punctual performance and
observance of each and every covenant and condition of this Agreement to be
performed and observed by Holdings.

          Section IX.4.  Reports to Holders.  Notwithstanding that Holdings may
not be required to remain subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, Holdings shall file with the Commission and provide
the Warrant Agent and the Holders with such annual reports and such information,
documents and other reports specified in Section 13 and 15(d) of the Exchange
Act, such information, documents and other reports to be so filed and provided
at the times specified for the filing of such information, documents and reports
under such Sections.

          Section IX.6.  Governing Law.  The laws of the State of New York
applicable to contracts to be performed entirely in that state shall govern this
Agreement.

          Section IX.7.  Binding Effect.  This Agreement shall be binding upon
and inure to the benefit of Holdings and the Warrant Agent and their respective
successors and assigns, and the Holders from time to time of the Warrants.
Nothing in this Agreement is intended or shall be construed to confer upon any
Person, other than Holdings, the Warrant Agent and the Holders of the Warrants,
any right, remedy or claim under or by reason of this Agreement or any part
hereof.

          Section IX.8.  Counterparts.  This Agreement may be executed manually
or by facsimile in any number of counterparts, each of which shall be deemed an
original, but all of which together constitute one and the same instrument.

          Section IX.9.  Amendments.  The Warrant Agent may, without the consent
or concurrence of the Holders of the Warrants, by supplemental agreement or
otherwise, join with Holdings in making any changes or corrections in this
Agreement, subject to both parties' agreement in writing thereof, that (a) are
required to correct any defective or inconsistent provision or clerical omission
or mistake or manifest error herein contained or (b) add to the covenants and
agreements of Holdings in this Agreement further covenants and agreements of
Holdings thereafter to be

                                       18
<PAGE>
 
observed, or surrender any rights or power reserved to or conferred upon
Holdings in this Agreement; provided that in either case such changes or
corrections do not and will not adversely affect, alter or change the rights,
privilege or immunities of the Holders of Warrants. Any amendment or supplement
to this Agreement that has an adverse effect on the interests of the Holders of
the Warrants shall require the written consent of the Holders of two-thirds of

          THE COMMON STOCK EVIDENCED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED
          UNDER THE U.S. SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND

          TO CLAUSE (ii) OF THE PRECEDING SENTENCE MUST BE ACCOMPANIED BY SUCH
          CERTIFICATIONS, LEGAL OPINIONS AND OTHER INFORMATION AS ARE REASONABLY

          This certifies that __________________, or its registered assigns, is
the owner of the number of Warrants set forth above, each of which represents
the right to purchase, commencing July 10, 1997, from STERLING CHEMICALS
HOLDINGS, INC., a Delaware corporation ("Holdings"), one share of Common Stock,
par value $.01 per share (the "Common Stock"), of Holdings (subject to
adjustment as provided in the Warrant Agreement hereinafter referred to) at the
purchase price (the "Exercise Price") of $.01 per share of Common Stock, upon
surrender hereof at the office of Harris Trust and Savings Bank or to its
successor as the warrant agent under the Warrant Agreement hereinafter referred
to (any such warrant agent being herein call the "Warrant Agent"), with the
Subscription Form on the reverse hereof duly executed, with signature guaranteed
as therein specified and simultaneous payment in full (by wire transfer or by
certified or official bank or bank cashier's check payable to the order of
Holdings, or by the surrender of Warrants having an aggregate Spread (as defined
in the Warrant Agreement) equal to the Exercise Price of the Warrants being
exercised) of the purchase price for the shares as to which the Warrant(s)
represented by this Warrant Certificate are exercised, all subject to the terms
and conditions hereof and of the Warrant Agreement.  Notwithstanding the
foregoing, Holdings shall have the right to not allow an exercise of any
Warrants in the event the Registration Statement is not effective and available
at the time Warrants are exercised, unless prior to the exercise of such
Warrants, the Holder thereof furnishes to the Warrant Agent and Holdings such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such exercise is being made pursuant to an
exemption from the registration requirements of the Securities Act.

          This Warrant Certificate is issued under and in accordance with a
Warrant Agreement dated as of July 10, 1997 (the "Warrant Agreement"), between
Holdings and Harris Trust and Savings Bank, as Warrant Agent, and is subject to
the terms and provisions contained therein, all of which terms and provisions
the Holder of this Warrant Certificate consents to by acceptance hereof. The
Warrant Agreement is hereby incorporated herein by reference and made a part
hereof. Reference is hereby made to the Warrant Agreement for a full description
of the rights, limitations of rights, obligations, duties and immunities
thereunder of Holdings and the Holders of the Warrants. The summary of the terms
of the Warrant Agreement contained in this Warrant Certificate is qualified in
its entirety by express reference to the Warrant Agreement. All terms used in
this Warrant Certificate that are defined in the Warrant Agreement shall have
the meanings assigned to them in the Warrant Agreement.

          Copies of the Warrant Agreement are on file at the office of the
Warrant Agent and may be obtained by writing to the Warrant Agent at the
following address:

          Harris Trust and Savings Bank
          700 Louisiana Street
          Suite 3350
          Houston, Texas  77002
          Attention:  Ray G. Rosenbaum

          If Holdings merges or consolidates with or into, or sells all or
substantially all of its property and assets to, another Person solely for cash,
or in the event of the dissolution, liquidation or winding-up of Holdings, the
Holders of Warrants shall be entitled to receive distributions on the date of
such event on an equal basis with holders of Common Stock (or other securities
issuable upon exercise of the Warrants) as if the Warrants had been exercised
immediately prior to such event (less the Exercise Price).

          The number of shares of Common Stock purchasable upon the exercise of
each Warrant is subject to adjustment as provided in the Warrant Agreement.
Except as stated in the immediately preceding paragraph, in the event Holdings
merges or consolidates with, or sells all or substantially all of its assets to,
another Person, each Warrant will, upon exercise, entitle the Holder thereof to
receive the number of shares of capital stock or other securities or the amount
of money and other property which the holder of a share of Common Stock (or
other securities or property issuable upon exercise of a Warrant) is entitled to
receive upon completion of such merger, consolidation or sale.

          As to any final fraction of a share which the same Holder of one or
more Warrants would otherwise be entitled to purchase upon exercise thereof in
the same transaction, Holdings shall pay the cash value thereof determined as
provided in the Warrant Agreement.

          All Common Stock or other securities issuable by Holdings upon the
exercise of Warrants shall be validly issued, fully-paid and nonassessable, and
Holdings shall pay all taxes and other governmental charges that may be imposed
under the laws of the United States of America or any political subdivision or
taxing authority thereof or therein in respect of the issue or delivery of such
shares or of other securities deliverable upon exercise of Warrants.  Holdings
shall not be required, however, to pay any tax or other charge imposed in
connection with any transfer involved in the issue of any certificate for Common
Stock, and in such case Holdings shall not be required to issue or deliver any
stock certificate until such tax or other charge has been paid or it has been
established to the Warrant Agent's and Holdings' satisfaction that no tax or
other charge is due.

          This Warrant Certificate and all rights hereunder are transferable by
the registered Holder hereof, in whole or in part, in accordance with the
provisions of the Warrant Agreement, on the register of Holdings maintained by
the Warrant Agent for such purpose at its office in New Houston, Texas, upon
surrender of this Warrant Certificate duly endorsed, or accompanied by a written
instrument of transfer form satisfactory to Holdings and the Warrant Agent duly
executed, with signatures guaranteed as specified in the attached Form of
Assignment, by the registered Holder hereof or his attorney duly authorized in
writing and upon payment of any necessary transfer tax or other governmental
charge imposed upon such transfer.  Upon any partial transfer, Holdings will
issue and the Warrant Agent will deliver to such Holder a new Warrant
Certificate or Certificates with respect to any portion not so transferred.
Each taker and Holder of this Warrant Certificate, by taking and holding the
same, consents and agrees that prior to the registration of

                                      A-3
<PAGE>
 
transfer as provided in the Warrant Agreement, Holdings and the Warrant Agent
may treat the person in whose name the Warrants are registered as the absolute
owner hereof for any purpose and as the Person entitled to exercise the rights
represented hereby, any notice to the contrary notwithstanding.

          This Warrant Certificate may be exchanged, in accordance with the
terms of the Warrant Agreement, at the office of the Warrant Agent maintained
for such purpose in Houston, Texas for Warrant Certificates representing the
same aggregate number of Warrants, each new Warrant Certificate to represent
such number of Warrants as the Holder hereof shall designate at the time of such
exchange.

          Prior to the exercise of the Warrants represented hereby, the Holder
of this Warrant Certificate, as such, shall not be entitled to any rights of a
stockholder of Holdings, including, without limitation, the right to vote or to
consent to any action of the stockholders, to receive dividends or other
distributions, to exercise any preemptive right or to receive any notice of
meetings of stockholders, and shall not be entitled to receive any notice of any
proceedings of Holdings except as provided in the Warrant Agreement.

          This Warrant Certificate shall be void and all rights evidenced hereby
shall cease on December 1, 2007, unless sooner terminated by the liquidation,
dissolution or winding-up of Holdings or as otherwise provided in the Warrant
Agreement upon the consolidation or merger of Holdings with, or sale of Holdings
to, another Person.

agrees to vote (or cause to be voted) the Voting Stock owned by it in favor of
the Clipper Designee and to take any other necessary or desirable action in its
capacity as a stockholder of the Company to cause the Clipper Designee to be
elected to the Board.  Without limitation of the foregoing, Koch agrees to cause
the Koch Director to vote in favor of the Clipper Designee and each Stockholder
who is a member of the Board agrees, subject to his fiduciary duties, to vote in
favor of the Clipper Designee.

          (b) In the event Clipper shall make an Interim Clipper Designation in
accordance with paragraph (a) above in order to fill the vacancy created by the
death, resignation or removal of the Clipper Director and in the event a
majority of the directors remaining in office shall fail or refuse to appoint
the Clipper Designee to fill such vacancy within 30 days after receipt by the
Company of such Interim Clipper Designation, then the Company agrees, if
requested by Clipper to do so, to call a special meeting of the stockholders of
the Company for the purpose of voting upon a proposal to elect the Clipper
Designee to the Board; provided, however, that in no event shall the Company be
required to call a special meeting of the stockholders if the Company has given
a formal notice of the next Annual Meeting.

          3.4. Failure of Clipper to Designate.  If the Clipper Representative
shall fail or refuse to designate a nominee for director pursuant to Section 3.2
or 3.3, such directorship shall remain vacant unless and until such designation
shall be made as provided in this Article III; provided, however, that if such
vacancy results in less than the minimum number of directors required by law or
by the charter or bylaws of the Company as then in effect, such vacancy shall be
filled by an individual elected by a majority of the directors then serving.

          3.5. Removal of Clipper Director.  The Clipper Representative shall
have the exclusive right (except as otherwise provided by applicable law or the
Company's charter) to remove or replace the Clipper Director.  If the Clipper
Representative desires to remove the Clipper Director, it shall give written
notice of such desire to the Company and the other Stockholders who shall

                                      -4-
<PAGE>
 
thereupon become obligated to vote all Voting Stock owned by them in favor of
the removal of the Clipper Director.  No Stockholder (other than the Clipper
Investors) shall vote any of the securities of the Company owned by it or take
any other action in its capacity as a stockholder of the Company for the removal
of the Clipper Director without the prior written approval of the Clipper
Representative.

          3.6. The Clipper Observer.  The Clipper Representative shall have the
right, exercisable by written notice to the Company, to designate from time to
time an observer (the "Clipper Observer") who shall have the right to attend
meetings of the Board and to receive information delivered to the Board, at the
expense of the Clipper Investors.  The initial Clipper Observer shall be Kevin
A. Macdonald.

          3.7. Termination/Suspension of Clipper Rights.  Notwithstanding
anything in this Agreement to the contrary, the rights of the Clipper Investors
and the Clipper Representative under this Article III and the obligations of the
other parties hereto under this Article III shall terminate immediately and
without notice upon the earlier of (i) the termination of this Agreement under
Section 7.3 and (ii) any event or occurrence resulting in the holding by the
Clipper Investors of less than 5% of the outstanding shares of Common Stock.
Promptly upon the termination of its rights under this Article III, the Clipper
Investors agree to (i) cause the resignation of, or provide notice to the other
parties hereto as provided in Section 3.5 requesting the removal of, the
incumbent Clipper Director and (ii) inform the Clipper Observer that his rights
under Section 3.6 have terminated.

          3.8. Irrevocable Proxy.  Each of the Stockholders hereby grants to the
Clipper Representative, on behalf of  the Clipper Investors, an irrevocable
proxy to vote all shares of Common Stock presently or at any future time owned
beneficially or of record by such Stockholder which the Stockholder is entitled
to vote, and to represent and otherwise act as such Stockholder could act, in
the same manner and with the same effect as if such Stockholder were personally
present, at any annual, special or other meeting of the stockholders of the
Company, and at any adjournment thereof, or pursuant to any written consent in
lieu of meeting or otherwise; provided, however, that any such vote or consent
in lieu thereof or any other action so taken shall be solely for the purposes of
electing a Clipper Designee to the Board as provided in Section 3.2 or 3.3 or
removing the Clipper Director from the Board as provided in Section 3.5.

                                   ARTICLE IV
                               The Koch Director

          4.1. General.  Koch shall be entitled to designate one individual as a
director nominee to serve on the Board. Such designation shall be made annually
as provided in Section 4.2 or at other times as provided in Section 4.3. The
parties hereto acknowledge that George B. Gregory has heretofore been designated
and elected as the initial Koch Director.  The Koch Director shall serve on the
Board until a successor director shall be duly elected and qualified or until
his earlier death, removal or resignation.

                                      -5-

          4.2. Annual Koch Designations.  The Company shall, no later than 45
days prior to the mailing of any proxy statement with respect to an Annual
Meeting, notify Koch of the date of such mailing.  As soon as practicable after
receipt of such notice but in any event no later than 20 days prior to the
mailing date specified therein, Koch shall provide the Company a written
statement ("Annual Koch Designation") designating either the incumbent Koch
Director or a person other than the incumbent Koch Director, in which event the
Annual Koch Designation shall include such other person's name, age, principal
occupation, business address and telephone number and residence address and
telephone number.  The Annual Koch Designation shall also include or be
accompanied by (i) all information relating to the person designated therein
that is required to be disclosed in the proxy statement pursuant to applicable
regulations of the Securities and Exchange Commission, (ii) such person's
consent to being named in the proxy statement as a nominee and (iii) a statement
of such person's intention to serve as a director if elected to the Board. The
Company shall nominate for election at such Annual Meeting the person designated
in the Annual Koch Designation. Subject to applicable laws, the Company agrees
to take all other actions reasonably necessary to cause the Koch Designee to be
elected to the Board. Each Stockholder agrees to vote (or cause to be voted) the
Voting Stock owned by it in favor of the Koch Designee and to take any other
necessary or desirable action in its capacity as a stockholder of the Company to
elect the Koch Designee to the Board.

          4.3. Interim Koch Designations.  (a)  In case a vacancy shall occur on
the Board because of the death, resignation or removal of the Koch Director,
Koch may elect either (i) to have such vacancy filled at the next Annual Meeting
pursuant to a designation made in accordance with Section 4.2 or (ii) to have
such vacancy filled prior to such Annual Meeting by a majority of the directors
remaining in office.  If Koch wishes to make the election provided for in clause
(ii) above, it shall designate a successor director nominee by written notice
given to the Company and each of the other Stockholders (the "Interim Koch
Designation").  Subject to applicable laws, the Company shall recommend that the
remaining directors elect the Koch Designee and shall take all other actions
reasonably necessary to cause the Koch Designee to be elected to the Board.
Each Stockholder agrees to vote the Voting Stock owned by it in favor of the
Koch Designee and to take any other necessary or desirable action in its
capacity as a stockholder of the Company to cause the Koch Designee to be
elected to the Board.  Without limitation of the foregoing, the Clipper
Investors agrees to cause the Clipper Director to vote in favor of the Koch
Designee and each Stockholder who is a member of the Board agrees, subject to
his fiduciary duties, to vote in favor of the Koch Designee.

          (b) In the event Koch shall make an Interim Koch Designation in
accordance with paragraph (a) above in order to fill the vacancy created by the
death, resignation or removal of the Koch Director and in the event a majority
of the directors remaining in office shall fail or refuse to appoint the Koch
Designee to fill such vacancy within 30 days after receipt by the Company of
such Interim Koch Designation, then the Company agrees, if requested by Koch to
do so, to call a special meeting of the stockholders of the Company for the
purpose of voting upon a proposal to elect the Koch Designee to the Board;
provided, however, that in no event shall the Company be required to call a
special meeting of the stockholders if the the Company has given a formal notice
of the next Annual Meeting.

          4.4. Failure of Koch to Designate.  If Koch shall fail or refuse to
designate a nominee for director pursuant to Section 4.2 or 4.3, such
directorship shall remain vacant unless and until such designation shall be made
as provided in this Article IV; provided, however, that if such vacancy results
in less than the minimum number of directors required by law or by the charter
or bylaws of the Company as then in effect, such vacancy shall be filled by an
individual elected by a majority of the directors then serving.

          4.5. Removal of Koch Director.  Koch shall have the exclusive right
(except as otherwise provided by applicable law) to remove or replace the Koch
Director.  If Koch desires to remove the Koch Director, it shall give written
notice of such desire to the Company and the other Stockholders who shall
thereupon become obligated to vote all Voting Stock owned by them in favor of
the removal of the Koch Director.  No Stockholder (other than  Koch) shall vote
any of the securities of the Company owned by it or take any other action in its
capacity as a stockholder of the Company for the removal of the Koch Director
without the prior written approval of Koch.

          4.6. Termination/Suspension of Koch Rights.  Notwithstanding anything
in this Agreement to the contrary, the rights of Koch under this Article IV and
the obligations of the other parties hereto under this Article IV shall
terminate immediately and without notice upon the earlier of (i) the termination
of this Agreement under Section 7.3 and (ii) any event or occurrence resulting
in the holding by Koch of less than 5% of the outstanding shares of Common
Stock.  Promptly upon the termination of its rights under this Article IV, Koch
agrees to cause the resignation of, or provide notice to the other parties
hereto as provided in Section 4.5 requesting the removal of, the incumbent Koch
Director.

          4.7. Irrevocable Proxy.  Each of the Stockholders hereby grants to
Koch an irrevocable proxy to vote all shares of Common Stock presently or at any
future time owned beneficially or of record by such Stockholder which the
Stockholder is entitled to vote, and to represent and otherwise act as such
Stockholder could act, in the same manner and with the same effect as if such
Stockholder were personally present, at any annual, special or other meeting of
the stockholders of the Company, and at any adjournment thereof, or pursuant to
any written consent in lieu of meeting or otherwise; provided, however, that any
such vote or consent in lieu thereof or any other action so taken shall be
solely for the purposes of electing a Koch Designee to the Board as provided in
Section 4.2 or 4.3 or removing the Koch Director from the Board as provided in
Section 4.5.



                                   ARTICLE V
               Certain Restrictions on Sale of Common Stock, etc.

owned by any Stockholder shall bear the following legend:

                                      -7-
<PAGE>
 
          The shares represented by this certificate are subject to the terms
          and conditions of a Voting Agreement, a copy of which is on file with
          the Secretary of Sterling Chemicals Holdings, Inc., and are held and
          may be sold, assigned, transferred or otherwise disposed of only in
          accordance with such agreement.

          (b) Upon the termination of this Agreement under Section 7.3, the
Company shall, without charge and upon surrender of certificates by the holders
thereof and written request of such holders, cancel all certificates evidencing
shares of Common Stock bearing the legend described above and issue to the
holders thereof replacement certificates that do not bear such legend for an
equal number of shares held by such holders.  Upon the transfer of any Common
Stock bearing the legend described above to a party believed by the Company to
be not bound by and subject to this Agreement by virtue of Section 7.2, the
Company shall, without charge and upon surrender of certificates by the holders
thereof and written request of either the transferor or transferee, cancel all
certificates evidencing such shares of Common Stock and issue to the transferee
thereof replacement certificates that do not bear such legend.

          5.2. Voting Trusts, etc.  No Stockholder shall deposit any shares of
Common Stock in a voting trust or subject any shares of Common Stock to any
arrangement or agreement (other than this Agreement) with respect to the voting
of such shares unless such trust or arrangement or agreement is made expressly
subject to the provisions of this Agreement.  Except as provided in this
Agreement, no Stockholder shall give any proxy or power of attorney with respect
to any shares of Common Stock that permits the holder thereof to vote such
shares in its discretion in an election of directors or for the removal of the
Clipper Director or the Koch Director unless such proxy or power of attorney is
made expressly subject to the provisions of this Agreement.

                                   ARTICLE VI
                         Representations and Warranties

          Each party hereto hereby represents and warrants, severally and not
jointly, to each other party hereto as follows:

     party nor the consummation by such party of the transactions contemplated
     hereby will conflict with or constitute a violation of or default under any
     contract, commitment, agreement, arrangement or restriction of any kind to

parties, may designate additional or different addresses for subsequent notices
or communications.

          7.9. Counterparts.  This Agreement may be executed in counterparts,

together shall constitute one and the same agreement.

          7.10.     Entire Agreement.  This Agreement contains the entire
agreement among the parties hereto with respect to the subject matter hereof and
supersedes all prior arrangements or understandings with respect to the subject
matter hereof.
