                    NOTICE OF ANNUAL MEETING OF STOCKHOLDERS
                           TO BE HELD JANUARY 24, 2001

To Our Stockholders:

         You are cordially invited to attend our Annual Meeting of Stockholders
to be held in Rooms Cottonwood A and B of the Hyatt Regency Hotel at 1200
Louisiana Street, Houston, Texas at 9:00 a.m. (Houston time) on Wednesday,
January 24, 2001. At the Annual Meeting you will be asked to vote on each of the
following proposals:

         o    the election of six directors, each of whom will hold office until
              our Annual Meeting of Stockholders in 2002 and until his successor
              has been duly elected and qualified;

         o    the ratification and approval of the appointment of Deloitte &
              Touche LLP as our independent accountants for the fiscal year
              ending September 30, 2001;

         o    the ratification and approval of an Amendment to the Sterling
              Chemicals Holdings, Inc. Omnibus Stock Awards and Incentive Plan
              increasing the number of shares available for awards thereunder
              from 1,000,000 to 2,000,000; and

         o    the adoption of an amendment to our Certificate of Incorporation
              increasing the number of authorized shares of our common stock
              from 20,000,000 shares to 35,000,000 shares.

You are entitled to vote on each of these proposals if you were a stockholder at
the close of business on December 4, 2000. Our Board of Directors recommends a
vote FOR each of the nominated directors and FOR each of the other proposals.
You may also be asked to consider and act upon any other business that may
properly come before the Annual Meeting or any adjournment or postponement
thereof.

         Your vote is very important. If you do not expect to attend the Annual
Meeting in person, please sign, date and complete the enclosed proxy and return
it without delay in the enclosed envelope, which requires no postage if mailed
in the United States. Mailing your completed proxy will not prevent you from
later revoking that proxy and voting in person at the Annual Meeting. If you
want to vote at the Annual Meeting but your shares are held by an intermediary,
such as a broker or bank, you will need to obtain proof of ownership of your
shares as of December 4, 2000 from the intermediary.

                                              By Order of the Board of Directors

                               PROXY STATEMENT FOR
                         ANNUAL MEETING OF STOCKHOLDERS
                           TO BE HELD JANUARY 24, 2001


GENERAL INFORMATION

Purpose of this Proxy Statement

We have prepared this Proxy Statement to solicit proxies on behalf of our Board
of Directors for use at our 2001 Annual Meeting and any adjournment or
postponement thereof. We intend to mail this Proxy Statement and accompanying
proxy card to all of our stockholders entitled to vote at the Annual Meeting on
or about December 22, 2000.

Time and Place of Annual Meeting

The Annual Meeting will be held on Wednesday, January 24, 2001, at 9:00 a.m.
(Houston time) in Rooms Cottonwood A and B of the Hyatt Regency Hotel at 1200
Louisiana Street, Houston, Texas.

Who May Vote

If you owned any shares of our common stock on December 4, 2000, as reflected in
our stock register, you may vote at the Annual Meeting.

How to Vote

You may vote in person at the Annual Meeting or by proxy. We recommend you vote
by proxy even if you plan to attend the Annual Meeting. You can always change
your vote at the Annual Meeting. If you want to vote at the Annual Meeting but
your shares are held by an intermediary, such as a broker or bank, you will need
to obtain proof of ownership of your shares as of December 4, 2000, or a proxy
to vote your shares, from the intermediary.

Quorum

In order to carry on any business at the Annual Meeting we must have a quorum.
This means that at least a majority of our outstanding shares eligible to vote
at the Annual Meeting must be represented at the Annual Meeting, either in
person or by proxy. Any shares owned by us or any of our subsidiaries are not
counted for this purpose. Shares of our common stock held by intermediaries that
are voted for at least one matter at the Annual Meeting will be counted as being
present for purposes of determining a quorum for all matters, even if the
beneficial owner's discretion has been withheld for voting on some or all other
matters (commonly referred to as a "broker non-vote").

Outstanding Shares

On December 4, 2000, there were 12,999,979 shares of our common stock
outstanding, 215,972 of which were held by Sterling Chemicals, Inc., our
wholly-owned subsidiary.

List of Stockholders

A list of our stockholders entitled to vote at the Annual Meeting will be
available for inspection at the Annual Meeting, as well as at our offices at
1200 Smith Street, Suite 1900, Houston, Texas 77002 for ten days prior to the
Annual Meeting. Any inspection of this list at our offices will need to be
conducted between 7:30 a.m. and 4:30 p.m. (Houston time). Please contact our
Corporate Secretary prior to coming to our offices to conduct an inspection.

<PAGE>   5

Votes Needed

Each share of our common stock is entitled to cast one vote for each director to
be elected and one vote on each other matter voted on at the Annual Meeting.
Directors will be elected by the favorable vote of a plurality of our shares of
common stock that are entitled to vote and are present at the Annual Meeting, in
person or by proxy, meaning that the six candidates with the largest number of
affirmative votes will be elected as our directors. Under this format,
abstentions and broker non-votes will not affect the outcome of the election.

Adoption of the amendment to our Certificate of Incorporation will require the
favorable vote of a majority of the shares of our common stock that are entitled
to vote on the adoption. Therefore, on this matter, abstentions from voting and
broker non-votes will have the same effect as a vote against the proposal.

Ratification and approval of the appointment of Deloitte & Touche LLP as our
independent accountants for fiscal 2001 and ratification and approval of the
Amendment to our Omnibus Plan, as well as any other business that may properly
come before the Annual Meeting for a vote, will require the favorable vote of a
majority of the shares of our common stock that are entitled to vote on the
matter and are present at the Annual Meeting, in person or by proxy (unless a
greater vote is required by law or our charter or bylaws). Therefore, on these
matters, an abstention from voting will have the same effect as a vote against
the proposal. However, broker non-votes are considered not to be present for
voting on these matters and, consequently, do not count as votes for or against
these proposals and are not considered in calculating the number of votes
necessary for approval.

Solicitation of Proxies and Expenses

We are asking for your proxy on behalf of our Board. We will bear the entire
cost of preparing, printing and soliciting proxies. We will send proxy
solicitation materials to all of our stockholders of record as of December 4,
2000 and to all intermediaries, such as brokers and banks, that held any of our
shares on that date on behalf of others. These intermediaries will then forward
solicitation materials to the beneficial owners of our shares and we will
reimburse them for their reasonable forwarding expenses. Our directors, officers
and employees may also solicit proxies in person or by telephone.

How Proxies Work

Giving us your proxy means that you are authorizing us to vote your shares at
the Annual Meeting in the manner you direct. You may vote for all, some or none
of our director candidates. You may also vote for or against the other proposals
or abstain from voting.

If you sign and return the enclosed proxy card and do not withhold authority to
vote for the election of any of our director candidates, all of your shares will
be voted for the election of each of our director candidates. If you withhold
authority to vote for any of our director candidates, none of your shares will
be voted for those candidates but all of your shares will be voted for the
election of the candidates as to whom you have not withheld authority to vote.

If any of our director candidates becomes unavailable for any reason before the
election, we may reduce the number of directors serving on our Board or our
Board may designate a substitute candidate. We have no reason to believe that
any of our director candidates will be unavailable. If our Board designates a
substitute candidate, the persons named in the enclosed proxy card will vote
your shares for such substitute if they are instructed to do so by our Board or,
if our Board does not do so, in accordance with their own best judgment.

If you sign and return the enclosed proxy card but do not specify how you want
your shares voted, your shares will be voted in favor of each of our director
candidates, in favor of the proposal to ratify and approve the appointment of
Deloitte & Touche LLP as our independent accountants for fiscal 2001, in favor
of the proposal to ratify and approve the Amendment to our Omnibus Plan


                                      -2-
<PAGE>   6

and in favor of the adoption of the amendment to our Certificate of
Incorporation.

If you sign and return the enclosed proxy card and any additional business
properly comes before the Annual Meeting, the persons named in the enclosed
proxy card will vote your shares on those matters as instructed by our Board or,
in the absence of any express instructions, in accordance with their own best
judgment. As of the date of this Proxy Statement, we were not aware of any other
matter to be raised at the Annual Meeting.

You may receive more than one proxy or voting card depending on how you hold
your shares. If your hold your shares through someone else, such as a broker or
a bank, you may get materials from them asking you how you want your shares
voted.

Revoking a Proxy

You may revoke your proxy at any time before your shares are voted by providing
our Corporate Secretary with either a new proxy with a later date or a written
notice of your desire to revoke your proxy at the following address: Sterling
Chemicals Holdings, Inc., 1200 Smith Street, Suite 1900, Houston, Texas 77002;
Attention: Corporate Secretary. You may also revoke your proxy at any time prior
to your shares having been voted by attending the Annual Meeting in person and
notifying the inspector of election of your desire to revoke your proxy.
However, your proxy will not automatically be revoked merely because you attend
the Annual Meeting.

Stockholders Proposals

Our Board of Directors does not intend to bring any other matters before the
Annual Meeting and has not been informed that any other matters are to be
presented by others. Our bylaws contain several requirements that must be
satisfied in order for any of our stockholders to bring a proposal before one of
our annual meetings, including a requirement of delivering proper advance notice
to us. Stockholders are advised to review our bylaws if they intend to present a
proposal at any of our annual meetings.

Annual Report and Available Information

Our annual report to stockholders, including financial statements, accompanies
this Proxy Statement but does not constitute a part of the proxy solicitation
materials. WE WILL FURNISH A COPY OF OUR ANNUAL REPORT ON FORM 10-K (INCLUDING
FINANCIAL STATEMENTS AND THE FINANCIAL STATEMENT SCHEDULES BUT WITHOUT EXHIBITS)
FOR OUR FISCAL YEAR ENDED SEPTEMBER 30, 2000, WITHOUT CHARGE, TO ANY PERSON
WHOSE VOTE IS SOLICITED BY THIS PROXY STATEMENT UPON WRITTEN REQUEST TO THE
FOLLOWING ADDRESS: STERLING CHEMICALS HOLDINGS, INC., 1200 SMITH STREET, SUITE
1900, HOUSTON, TEXAS 77002; ATTENTION: MANAGER OF INVESTOR RELATIONS. In
addition, upon written request, we will furnish a copy of any exhibit to our
annual report on Form 10-K to any person whose vote is solicited by this Proxy
Statement upon payment of our reasonable expenses incurred in connection with
providing the copy of the exhibit.

Inspector of Election

Our Board of Directors has appointed Katherine Holdsworth, our Assistant
Secretary, as the inspector of election. The inspector of election will
separately calculate affirmative and negative votes, abstentions and broker
non-votes for each of the proposals.

                                       Earlier in his career, Mr. Towe held
                                       various management positions over a
                                       period of nearly 20 years in Union
                                       Carbide Corporation, a multinational
                                       chemicals and plastics manufacturer. Mr.
                                       Towe also serves as a director of several
                                       private companies.

         The holders of 6,653,583 shares of our common stock, representing
approximately 52% of our outstanding shares, are parties to a Third Amended and
Restated Voting Agreement dated as of February 1, 1999. The parties to the
Voting Agreement and its most pertinent terms are described in detail in this
Proxy Statement under the heading "Certain Transactions." The parties to the
Voting Agreement are required to vote all of their shares of our common stock in
favor of three nominees to our Board; one to be designated by certain affiliates
of Clipper Capital Partners, L.P. who are commonly referred to collectively as
"The Clipper Group," one to be designated by Gordon A. Cain and one to be
designated by Koch Capital Services, Inc. Mr. Towe is the current designee of
The Clipper Group. William A. McMinn was Mr. Cain's designee until his
resignation from our Board on October 26, 2000. Mr. Cain has the right to
designate Mr. McMinn's replacement and, upon any such designation, the existing
members of our Board will elect Mr. Cain's designee to our Board. Koch Capital
has waived its right to designate a member of our Board.

DIRECTOR COMPENSATION

         Any of our employees who serve on our Board do not receive additional
compensation for serving on our Board, although all of our directors are
reimbursed for their travel expenses related to their services as a director.
Each of our non-employee directors is paid a fee of $2,500 per quarter for his
service as a director, with the exception that our Vice Chairman is paid $5,000
per quarter. Our non-employee directors also receive $1,000 for each Board
meeting they attend and $400 for each telephonic meeting in which they
participate that lasts at least 30 minutes. Members of our Board committees who
are not our employees are paid $700 for each committee meeting they attend,
unless that member also serves as Chairman of the committee, in which case he
receives $1,700 per meeting. Prior to April 26, 2000, the committee meeting
attendance fee for one of our non-employee directors who was serving as the
Chairman of one of our Board committees was $1,400. On April 26, 2000, our Board
also established an annual retainer of $1,000 to be paid to our non-employee
directors who are serving as the Chairman of one of our Board committees. George
J. Damiris, one of our former non-employee directors, is employed by Koch
Ventures, Inc. and, under established policies of Koch Ventures, Inc., all
compensation earned by Mr. Damiris during fiscal 2000 was paid directly to Koch
Ventures, Inc.

         Under our 1997 Nonqualified Stock Option Plan for Non-Employee
Directors, each of our non-employee directors received fully vested options to
purchase 1,000 shares of our common stock on October 1, 1999, with the exception
that our Vice Chairman received options to purchase 2,000 shares. Effective as
of April 26, 2000, our 1997 Nonqualified Stock Option Plan was amended and
restated as our Amended and Restated Stock Plan for Non-Employee Directors.
Under our Amended and Restated Stock Plan, each of our non-employee directors
will receive $15,000 in shares of our common stock and fully vested options to
purchase 2,000 shares of our common stock on October 1 of each year, starting
with October 1, 2000. The annual grant of shares under our Amended and Restated
Stock Plan is valued at the average market price for a share of our common stock
during the 90-day period ending on the date of grant. Under both our 1997
Nonqualified Stock Option Plan and our Amended and Restated Stock Plan, each of
our non-employee directors has the ability to elect not to participate. As
discussed in this Proxy Statement under "Certain Transactions," Koch Capital,
who holds a significant amount of our common stock, was given the right under a
Voting Agreement to designate a person for election to our Board. We previously
entered into an agreement with Koch Capital under which we agreed to issue to


                                      -6-
<PAGE>   10

Koch Capital the options that would have otherwise been granted to the director
it designates if its designee elects to not participate under the relevant Plan.
Koch Capital received options to acquire 1,000 shares under our 1997
Nonqualified Stock Option Plan during fiscal 2000 pursuant to this arrangement.
The terms and conditions of these options were substantially similar to those
governing the options granted to our other non-employee directors, with the main
exception being that the options granted to Koch Capital did not immediately
expire upon the termination of service of its designated director. However, Koch
Capital has waived its right to designate a member of our Board under the Voting
Agreement and all options previously issued to Koch Capital under our 1997
Nonqualified Stock Option Plan have expired.

BOARD COMMITTEES

         Our Board of Directors has created various standing committees to help
carry out its duties, including a Compensation Committee and an Audit and
Compliance Committee. Generally speaking, our Board committees work on key
issues in greater detail than would be possible at full Board meetings. We do
not have a standing nominating committee.

Compensation Committee

         Our Compensation Committee is currently comprised of three of our
non-employee directors, Frank J. Hevrdejs (Chairman), Allan R. Dragone and Rolf
H. Towe, and met six times in fiscal 2000. Our Compensation Committee
establishes and reviews compensation for all of our elected officers and those
of our subsidiaries and also administers our executive compensation programs.
Our Compensation Committee consults, from time to time, with outside experts
concerning the performance of its duties.

Audit and Compliance Committee

         Our Audit and Compliance Committee is currently comprised of two of our
non-employee directors, Hunter Nelson (Chairman) and Robert W. Roten, and met
nine times in fiscal 2000. A vacancy currently exists on our Audit and
Compliance Committee which will be filled through the appointment of one of our
non-employee directors to this Committee by our Board, upon its determination of
an appropriate individual. This Committee operates under a written charter
adopted by our Board, a copy of which is attached to this Proxy Statement as
Appendix A. Our Audit and Compliance Committee recommends the appointment of our
independent auditors to our Board, meets with these auditors to review their
report on the financial statements of our business and approves the audit and
other services to be provided by these auditors. In addition, our Audit and
Compliance Committee reviews our Form 10-K and Form 10-Q reports and our
practices in preparing published financial statements. Our Audit and Compliance
Committee also provides oversight with respect to the establishment of and
adherence to corporate compliance programs, codes of conduct and other policies
and procedures concerning our business and our compliance with all relevant
laws.

         Mr. Nelson is considered "independent" under the listing standards of
the New York Stock Exchange, the American Stock Exchange and the National
Association of Securities' Dealers. Mr. Roten is not considered independent
under any of these listing standards solely because he formerly served as our
President. Under each of the listing standards, a director is considered to be
not independent if he was employed by the relevant corporation or any of its
affiliates in any of the last three years. As Mr. Roten retired as our President
on March 31, 1998, and assuming that no events that impact the analysis of his
independence occur before March 31, 2001, Mr. Roten will be considered
independent under all of these listing standards on April 1, 2001.

         Our Audit and Compliance Committee has furnished the following report
for inclusion in this Proxy Statement.

Roles in Financial Reporting

         Sterling's management is responsible for Sterling's internal controls
and the financial reporting process. The independent accountants hired by
Sterling are responsible for performing an independent audit of Sterling's
consolidated financial statements in accordance with generally accepted auditing
standards and to issue a report thereon. The Committee's responsibility is to
monitor and oversee these processes.

Fiscal 2000 Financial Statements

         In order to fulfill our monitoring and oversight duties, we reviewed
the audited financial statements included in Sterling's Annual Report on Form
10-K for the fiscal year ended September 30, 2000 and we met and held
discussions with Sterling's management and Deloitte & Touche LLP, Sterling's
independent accountants, with respect to those financial statements. Management
represented to us that all of these financial statements were prepared in
accordance with generally accepted accounting principles. We also discussed with
Deloitte & Touche the matters required to be discussed by Statement on Auditing
Standards No. 61. Finally, we reviewed the written disclosures provided to us by
Deloitte & Touche, as required by Independence Standards Board Standard No. 1,
and we discussed with Deloitte & Touche its own independence. Based upon our
discussions with management and Deloitte & Touche and our review of Deloitte &
Touche's report and the representations of management, we recommended to
Sterling's Board of Directors that the audited financial statements for
Sterling's fiscal year ended September 30, 2000 be included in Sterling's Annual
Report on Form 10-K for the fiscal year ended September 30, 2000.

Additional Information

         No portion of this report shall be deemed to be incorporated by
reference into any filing under the Securities Act or under the Securities
Exchange Act through any general statement incorporating by reference the Proxy
Statement in which this report appears in its entirety, except to the extent
that Sterling specifically incorporates this report or a portion of this report
by reference. In addition, this report shall not otherwise be deemed to be filed
under either of such Acts.

                                           Respectfully submitted,

                                           The Audit and Compliance Committee
                                               of the Board of Directors

                                           T. Hunter Nelson (Chairman)
                                           Robert W. Roten

RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS
(Item 2 on the Proxy Card)

         Our Board, at the recommendation of our Audit and Compliance Committee,
has appointed Deloitte & Touche LLP as our independent accountants for the
fiscal year ending September 30, 2001. We are asking that you ratify that
appointment. Deloitte & Touche has been our independent accounting firm for our
last five fiscal years and we believe that they are well qualified for the job.
Representatives of Deloitte & Touche will be present at the Annual Meeting to
answer appropriate questions and to make a statement, if they desire to do so.

         OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL.

<PAGE>   13

RATIFICATION OF AMENDMENT TO OMNIBUS PLAN
(Item 3 on the Proxy Card)

         Our Board has unanimously approved the Amendment to our Omnibus Plan.
We are asking that you ratify and approve the Amendment. Our Omnibus Plan
authorizes the grant of various stock, stock-related and cash awards to our
employees. Our Omnibus Plan became effective as of April 23, 1997 and was
approved by our stockholders at their meeting held on January 28, 1998. The
purpose of our Omnibus Plan is to provide a means through which we may attract
and retain employees and a means through which those of our employees who are
responsible for our successful administration and management can acquire and
maintain stock ownership. We believe that our Omnibus Plan strengthens these
employees' concern for our welfare and their desire to remain our employees. Our
Omnibus Plan also provides these employees with additional incentive and reward
opportunities that are designed to enhance our profitable growth. Under the
Amendment to our Omnibus Plan, the total number of shares of our common stock
available for awards under the Plan will be increased from 1,000,000 to
2,000,000 shares.

         OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL.


              The full text of our Omnibus Plan, as amended by the Amendment, is
set forth in Appendix B to this Proxy Statement. The basic features of our
Omnibus Plan are summarized below. However, this summary is qualified in its
entirety by reference to the full text of our Omnibus Plan.

Eligibility

              All of our officers and employees are eligible to receive awards
under our Omnibus Plan. We currently have approximately 1,112 officers and
employees who are eligible to participate under our Omnibus Plan.

Administration

              Our Omnibus Plan is administered by our Compensation Committee,
which is comprised solely of "outside directors" who are "disinterested persons"
under the Internal Revenue Code and the Securities Exchange Act, respectively.
Our Compensation Committee selects the participants who will receive awards,
determines the type and terms of awards to be granted and interprets and
administers our Omnibus Plan.

Stock Subject to the Plan; Term

              If the Amendment to our Omnibus Plan is approved by our
stockholders, the number of shares of our common stock that may be awarded under
the Plan will be increased from 1,000,000 shares to 2,000,000 shares. In
addition, our Compensation Committee may adjust awards previously granted under
our Omnibus Plan to prevent dilution or enlargement of the rights of
participants under the Plan that would otherwise result from a stock dividend,
stock split, combination of shares, recapitalization, merger, consolidation,
reorganization or other similar corporate event. No awards may be granted under
our Omnibus Plan after April 23, 2007 but the Plan itself will remain in effect
until all awards granted under the Plan have been satisfied or expired. Our
Compensation Committee may, however, suspend or terminate our Omnibus Plan prior
to that time.


                                      -10-
<PAGE>   14

Types of Awards

              Under our Omnibus Plan, we may grant awards in the form of stock
options, stock appreciation rights (which are commonly referred to as "SARs"),
shares of restricted stock, performance awards and phantom stock to eligible
participants.


       o      Employee Stock Options. Stock options may be granted under our
              Omnibus Plan as incentive stock options ("ISOs") or non-qualified
              stock options. Our Compensation Committee determines the terms and
              conditions of each stock option award and has the authority to
              determine the form in which payment of the exercise price for any
              stock option may be made. However, the exercise price for an ISO
              cannot be less than the market value of a share of our common
              stock on the date of grant. In addition, an ISO may not be awarded
              to any of our employees who own more than 10% of the total
              combined voting power of all classes of our stock unless the ISO
              is not exercisable after five years from the date of grant and the
              exercise price for the ISO is at least 110% of the fair market
              value of a share of our common stock on the date of grant. Our
              Compensation Committee has generally imposed a five-year vesting
              schedule for all awards of stock options. However, any stock
              options granted under our Omnibus Plan become fully exercisable in
              the event of the optionee's termination of employment by reason of
              death, disability or retirement or in the event of a "change of
              control." No stock option granted under our Omnibus Plan may be
              exercised after the tenth anniversary of the date of grant or the
              earlier termination of the stock option. All stock options that
              have been awarded under our Omnibus Plan have been granted with an
              exercise price at or above the fair market value of a share of our
              common stock on the date of grant.

       o      Stock Appreciation Rights. SAR awards consist of the right to
              receive cash or shares of our common stock having a value equal to
              the amount, if any, by which the fair market value of a share of
              our common stock on the date the SAR is exercised exceeds the
              exercise price of the SAR. An SAR may be granted in tandem with
              stock options or separate and apart from a grant of stock options.
              Our Compensation Committee determines the exercise price of each
              SAR award and has the authority to determine the form in which
              payment of the exercise price for any SAR award may be made. The
              Compensation Committee may subject SAR awards to a vesting
              schedule; provided, however, that upon the death, disability or
              retirement of a grantee of an SAR award, or in the event of a
              change of control, the SAR award becomes fully exercisable.

       o      Restricted Stock. Restricted stock awards consist of the grant of
              shares of our common stock, subject to forfeiture over a specified
              period. A recipient of a restricted stock award obtains the
              immediate right to vote the shares, receive any dividends on the
              shares and otherwise enjoy the rights of a stockholder that
              pertain to the shares. However, the recipient of a restricted
              stock award may not sell or otherwise transfer those shares until
              any restrictions specified in the award expire. Our Compensation
              Committee determines the amount and form of payment (if any) for
              any shares of restricted stock awarded, sets the restrictions
              related to the award and the time at which those restrictions
              expire. If our Compensation Committee does not specify any amount
              of payment for an award of restricted stock, the recipient of the
              award is not required to make any payment for the shares unless
              otherwise required by law. The expiration of any restrictions on
              an award of restricted stock may be based on the attainment of
              certain financial targets established by our Compensation
              Committee or the recipient's continued employment with us for a
              specified period of time;


                                      -11-
<PAGE>   15

              provided, however, that upon the recipient's death, disability or
              retirement, or in event of a change of control, all restrictions
              automatically lapse or expire.

       o      Performance Awards. Performance awards consist of the right to
              receive payments in cash or shares of our common stock, subject to
              the achievement of certain performance goals. Our Compensation
              Committee sets the performance goals related to each performance
              award, the length of the period during which the award may be
              earned and the maximum value of the award. Performance goals may
              be based upon the recipient's individual performance, our
              performance as a whole or the performance of the business unit in
              which the recipient works. A performance award terminates,
              however, if the recipient of the award does not remain
              continuously employed by us during the performance period.

       o      Phantom Stock. Phantom stock awards consist of the right to
              receive payments in cash or shares of our common stock, subject to
              the fulfillment of conditions specified at the time of the award.
              Our Compensation Committee sets the conditions to payment of each
              phantom stock award. the length of the period during which the
              award will vest or may be earned and the maximum value of the
              award. A phantom stock award terminates, however, if the recipient
              of the award does not remain continuously employed by us during
              the vesting period.

Transferability; Exercise

              Awards under our Omnibus Plan are not transferable other than by
will or the laws of descent and distribution. In addition, during the lifetime
of a recipient of an award, the award may only be exercised by the recipient or
his or her guardian or legal representative. However, our Compensation Committee
may, in its discretion, provide at the time of the award of a particular stock
option (other than an ISO) that the stock option may be transferred by the
recipient, in whole or in part, subject to such terms and conditions as our
Compensation Committee may specify.

Federal Income Tax Consequences with Respect to Options

              The following summary is based on provisions of the Internal
Revenue Code and income tax regulations and proposed income tax regulations
thereunder. Our Omnibus Plan is not qualified under Section 401(a) of the
Internal Revenue Code.

       o      Non-Qualified Stock Options. No federal income tax is imposed on
              an optionee upon the grant of a non-qualified stock option. If a
              non-qualified stock option is exercised, the optionee will
              generally be treated as having received compensation taxable as
              ordinary income in the year of exercise in an amount equal to the
              amount by which the fair market value of the shares of our common
              stock acquired through the exercise of the option, as of the date
              of exercise, exceeds the aggregate exercise price paid for such
              shares. Upon any subsequent disposition of any of the shares of
              our common stock received upon exercise of the option, the
              optionee will be treated as having realized long-term or
              short-term capital gain or loss, depending on the holding period
              of the shares, in an amount equal to the difference between the
              fair market value of those shares as of the date of exercise of
              the stock option and the amount received for those shares in the
              disposition. If a non-qualified stock option is exercised, we may
              claim a deduction for "compensation paid" at the same time and in
              the same amount as income is recognized by the optionee, to the
              extent that this amount is an ordinary expense and satisfies the
              test of reasonable compensation.


                                      -12-
<PAGE>   16

       o      Incentive Stock Options. No federal income tax is imposed on the
              optionee upon the grant of an ISO. If an ISO is exercised, the
              optionee generally will not be treated as having received
              compensation taxable as ordinary income if the optionee does not
              dispose of the shares of our stock acquired through the exercise
              of the ISO within two years after the date of the grant of the ISO
              or within one year after the exercise of the ISO. However, the
              optionee may be subject to the tax adjustment described below
              under Alternative Minimum Tax. Upon any subsequent disposition of
              any shares of our common stock received upon exercise of an ISO,
              the optionee will be treated as having realized long-term or
              short-term capital gain or loss, depending on the holding period
              of those shares, in an amount equal to the difference between the
              aggregate exercise price paid for those shares as of the date of
              exercise of the ISO and the amount received for those shares in
              the disposition. If an ISO is exercised and the optionee holds the
              shares for the required time, we may not claim any deduction in
              connection with the grant or exercise of the ISO or the
              disposition of the shares of our common stock acquired through the
              exercise of the ISO.

              If the optionee disposes of any shares of our common stock
              acquired through the exercise of an ISO before the required time
              period has expired, the optionee will generally be treated as
              having received compensation taxable as ordinary income in the
              year of disposition of those shares in an amount equal to the
              amount equal to the lesser of (i) the difference between the fair
              market value of those shares as of the date of exercise and the
              aggregate exercise price paid for those shares and (ii) the
              difference between the amount realized upon the disposition of
              those shares and the aggregate exercise price paid for those
              shares. In addition, the optionee will be treated as having
              realized long-term or short-term capital gain or loss, depending
              on the holding period of the shares, in an amount equal to the
              difference between the amount received for those shares in the
              disposition and the amount reported as taxable ordinary income. If
              an ISO is exercised and the optionee does not hold the shares for
              the required time, we may claim a deduction for "compensation
              paid" at the same time and in the same amount as income is
              recognized by the optionee, to the extent that this amount is an
              ordinary expense and satisfies the test of reasonable
              compensation.

       o      Alternative Minimum Tax. The amount by which the fair market value
              of any shares of our common stock acquired through the exercise of
              an ISO exceeds the exercise price paid for such shares is an
              adjustment to alternative minimum taxable income for the
              optionee's taxable year in which the exercise occurs (unless those
              shares are disposed of in the same taxable year).

       o      Payment of Option Price in Shares. Our Compensation Committee may
              permit an optionee to pay the exercise price under a non-qualified
              stock option through the delivery of other shares of our common
              stock owned by the optionee having a fair market value equal to
              the exercise price. If an optionee pays the exercise price under a
              non-qualified stock option in this manner, the optionee will not
              realize any gain or loss on the exchange of the previously owned
              shares. The optionee's basis in the shares acquired through the
              exercise of the stock option will be split into two categories.
              For a number of shares equal to the number of previously owned
              shares delivered to pay the exercise price, the optionee will have
              the same basis as he or she had in the previously owned shares.
              For the remaining shares received through the exercise of the
              stock option, the optionee's basis will generally be equal to the
              fair market value of those shares at the time of exercise. In
              addition, the optionee will be


                                      -13-
<PAGE>   17

              treated as having received compensation taxable as ordinary income
              in an amount equal to the fair market value of these remaining
              shares at the time of exercise.

              Our Compensation Committee may also permit an optionee to pay the
              exercise price under an ISO through the delivery of other shares
              of our common stock owned by the optionee having a fair market
              value equal to the exercise price. If an optionee pays the
              exercise price under an ISO in this manner, the federal income tax
              consequences to the optionee will depend on the nature of the
              previously owned shares. If the previously owned shares were
              acquired through the exercise of a qualified stock option, an ISO
              or an option granted under an employee stock purchase plan and the
              shares are being transferred prior to the expiration of the
              applicable minimum statutory holding period, the transfer will be
              treated as a disqualifying disposition of the previously owned
              shares. If the previously owned shares were acquired in any of
              these manners but are being transferred after the applicable
              minimum statutory holding period, or were acquired in any other
              manner, the optionee will not realize any gain or loss on the
              exchange of the previously owned shares. In either case, the
              optionee's basis in the shares acquired through the exercise of
              the ISO will be split into two categories and all other ISO rules
              will apply. For a number of shares equal to the number of
              previously owned shares delivered to pay the exercise price, the
              optionee will have the same basis as he or she had in the
              previously owned shares, increased by any income recognized by the
              optionee in connection with any disqualifying disposition of the
              previously owned shares. For the remaining shares received through
              the exercise of the ISO, the optionee's basis will be zero. Upon
              any subsequent disqualifying disposition of any shares of our
              common stock received through the exercise of an ISO where the
              payment of the exercise price is made through the delivery of
              previously owned shares, the shares of our stock having the lowest
              basis will be treated as having been disposed of first.

Amendment and Termination

              Our Board, in its discretion, may amend, suspend or terminate our
Omnibus Plan at any time. However, any amendment, suspension or termination of
our Omnibus Plan by our Board is subject to approval by our stockholders if that
approval is required by law or our Board determines that such approval is
necessary to comply with the requirements of any securities exchange on which
our stock is listed or otherwise desires to have our stockholders approve the
relevant amendment, suspension or termination. Irrespective of any approval by
our stockholders, our Omnibus Plan may not be amended, suspended or terminated
in a manner that will terminate any outstanding awards or adversely affect the
rights of any participant under our Omnibus Plan in a material manner unless
that participant consents.

Grants Under the Omnibus Plan

              Future awards that may be made to our executive officers and other
employees under our Omnibus Plan are not presently determinable. Awards under
our Omnibus Plan are made at the discretion of our Compensation Committee in
accordance with the provisions of the Plan and our Compensation Committee's
compensation policies, which are discussed in the Compensation Committee Report
on Executive Compensation appearing in this Proxy Statement. The following table
sets forth certain information with respect to stock options granted under our
Omnibus Plan on or before December 4, 2000. Other than the options that were
originally granted on April 22, 1998, each of which was granted with a four-year
vesting period, all options were granted with five-year vesting periods and had
varying exercise prices depending on the fair market value of a share of our
common stock at the time of grant. In December of 1998, we reduced the exercise
price of all outstanding stock options held by our


                                      -14-

then current employees to $6.00 per share. On December 4, 2000, the closing
price of a share of our stock was $0.62.

ADOPTION OF AMENDMENT TO CERTIFICATE OF INCORPORATION
(Item 4 on the Proxy Card)

         Our Board of Directors has approved an amendment to our Certificate of
Incorporation to increase the total number of shares of stock we are authorized
to issue to 37,000,000, consisting of 35,000,000 shares of common stock, par
value $0.01 per share, and 2,000,000 shares of preferred stock, par value $0.01
per share. Currently, we are authorized to issue 20,000,000 shares of common
stock and 2,000,000 shares of preferred stock. As of the record date, 12,999,979
of such authorized shares were outstanding and 2,068,827 of such authorized
shares were reserved for issuance, leaving 4,931,194 shares of common stock
available for issuance for other corporate purposes as of that date. The
additional shares of common stock authorized by the proposed amendment to our
Certificate of Incorporation will be identical in all respects to our existing
common stock and will not carry any preemptive rights.

         We believe that the increase in the number of authorized shares of
common stock will provide us with increased flexibility to meet various
corporate objectives and is in our best interest and the best interest of our
stockholders. We have, in the past, financed a portion of acquisitions of other
companies through the issuance of various equity securities. In addition, in the
future, we may wish to issue equity securities in connection with further
acquisitions, our search for a new Chief Executive Officer or the improvement of
our capital structure. We also may wish to consider the issuance of additional
shares of common stock through stock dividends in appropriate circumstances.
Accordingly, the continued availability of shares of common stock is necessary
to provide us with the flexibility to take advantage of opportunities in such
situations. There are, at present, no understandings, agreements or arrangements
concerning the issuance of additional shares of common stock, except for shares
currently reserved for issuance under employee and director benefit plans and
our outstanding warrants. Pursuant to Delaware law, authorized and unissued
shares of common stock (other than those shares reserved for certain purposes)
are available for issuance by us to such persons and for such consideration as
our Board of Directors may determine from time to time. You may not be given the
opportunity to vote on such matters, unless stockholder approval is required by
applicable law or our Board of Directors in its judgment recommends stockholder
approval. You generally will not have preemptive rights to subscribe for newly
issued shares.

         We believe that the amendment to our Certificate of Incorporation will
provide flexibility needed to meet corporate objectives and is in our best
interests and your best interest. Even if the amendment is approved by our
stockholders, the amendment will not become effective until filed with the State
of Delaware. Our Board of Directors will determine if and when such filing will
be made.

         OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         Our executive compensation program is administered by the Compensation
Committee of our Board of Directors. This Committee, which is comprised of
non-employee directors, is responsible for discharging the compensation
responsibilities of our Board. This Committee reviews general compensation
issues and determines the compensation of all of our senior executives and other
key employees and recommends and administers our employee benefit plans that
provide benefits to our senior executives. Our Compensation Committee has
furnished the following report on executive compensation for inclusion in this
Proxy Statement.

Compensation Philosophy and Objectives

         Sterling's senior executive compensation program is designed to
motivate, reward and retain the management talent needed to achieve its business
goals and maintain a leadership position in the petrochemicals industry. Under
this program, a significant portion of the potential compensation of Sterling's
senior executives is dependent on increased stockholder value. This program
offers Sterling's senior executives salary levels and compensation incentives
designed to:

         o        attract, motivate and retain talented and productive
                  executives;

         o        recognize individual performance and Sterling's performance
                  relative to the performance of other companies of comparable
                  size, complexity and quality; and

         o        support Sterling's short-term and long-term goals.

We believe that this approach ensures an appropriate link between the
compensation of Sterling's senior executives and the accomplishment of
Sterling's goals and its stockholders' objectives.

         We use a number of sources to determine whether the compensation
program provided to Sterling's senior executives is competitive. Our primary
method of determining competitiveness involves obtaining compensation review
data from independent compensation consultants, which we use to compare our
compensation program to those offered by a group of chemical and allied products
corporations. We also compare our compensation program to those offered by a
select group of non-chemical companies that we feel are comparable in size and
performance. We do not compare our compensation program against those offered by
each of the companies included in the S&P Chemicals Index used in the Stock
Performance Graph contained in the Proxy Statement in which this report is
included because we do not consider many of those companies to be competitors of
Sterling, either in the market or for executive talent.

Total Compensation

         The three major components of Sterling's senior executive compensation
program are base salary, annual incentive compensation and stock-based
compensation. Our goal is to set base salaries for Sterling's senior executives
at or below competitive market rates of comparable companies, while providing
annual and stock-based compensation opportunities which are above competitive
market rates and are linked to Sterling's financial performance. We believe that
focusing executive compensation on variable incentive pay will help Sterling
meet its performance goals and enhance stockholder value in the long term.

Base Salaries

         Our strategy is to reduce the emphasis on fixed compensation for
Sterling's senior executives by positioning their base salaries at or below
industry levels. Initially, these base salaries are set at levels intended to
reflect the individual's experience, level of responsibility, job classification
and competence. Under our strategy, dramatic changes in base salary are not
generally made unless required to adjust for market movements, promotions or
significant changes in responsibility or individual performance. Except with
respect to the grant of stock options, Sterling's Board of Directors provides
final approval of the compensation of all of Sterling's senior executive
officers, including the Chairman of the Board and the Chief Executive Officer.


                                      -18-
<PAGE>   22

Annual Incentive Compensation

         Sterling's senior executives and other qualified employees can earn
additional cash compensation under Sterling's Profit Sharing Plan and Bonus
Plan. The additional compensation available under each of these plans is
intended to reward the achievement of annual corporate financial goals.
Generally, no additional compensation is available under either of the plans
unless Sterling's financial performance meets threshold levels established by us
and Sterling's Board of Directors at the beginning of each fiscal year. The
amount of additional compensation available under these plans is based on these
threshold levels, formulae set for the individual's job classification (with
individuals having greater management responsibility having the opportunity to
earn larger percentages) and on individual performance. We administer both of
these plans and recommend the total amount of annual compensation to Sterling's
Board of Directors. Sterling's Board of Directors approves the aggregate amount
of incentive compensation awards to all participants and we then approve
individual awards. In evaluating an individual's performance, we rely on the
members of Sterling's senior management. No awards were made under either plan
in fiscal 2000.

Stock-Based Compensation

         We are permitted to grant incentive stock options, non-qualified stock
options, stock appreciation rights, restricted stock awards, performance awards
and phantom stock awards to Sterling's senior executives and key employees under
Sterling's Omnibus Stock Awards and Incentive Plan. We determine the terms and
amounts of awards to be granted to individuals under the Omnibus Plan based upon
a variety of factors, including:

         o        level of responsibility and job classification;

         o        job performance;

         o        present and potential contributions to Sterling's long term
                  success; and

         o        the extent that the base salary of the individual is below
                  industry levels based on the compensation survey described
                  above.

The primary purpose of stock-based compensation is to provide Sterling's senior
executives and key employees with incentives to concentrate on Sterling's
performance over the long term. We believe that stock-based compensation is an
appropriate and effective method for aligning the interests of Sterling's senior
executives and key employees with Sterling's long term goal of maximizing
stockholder value because the employees will not receive any benefit from this
compensation unless the stock price rises.

         Sterling's Omnibus Plan permits us to specify the number of shares
covered by awards and the vesting schedule. We have generally imposed a
five-year vesting schedule for all awards in order to provide an incentive to
create stockholder value over time, since the full benefit of the awards cannot
be realized unless there is appreciation in stock value over a number of years.
However, options granted under the Omnibus Plan become fully exercisable in the
event of the optionee's termination of employment by reason of death, disability
or retirement and may become fully exercisable in the event of a "change of
control." No option may be exercised after the tenth anniversary of the date of
grant or the earlier termination of the option. All options are granted with an
exercise price at or above the fair market value of a share of Sterling's common
stock on the date of grant.

<PAGE>   23

         During fiscal 2000, we awarded non-qualified stock options to acquire
an aggregate of 100,500 shares of Sterling's common stock under the Omnibus
Plan. We did not make any other awards under the Omnibus Plan in fiscal 2000.
Also during fiscal 2000, options to acquire an aggregate of 27,070 shares of
Sterling's common stock expired as a result of resignations of several
employees.

Compensation to the Chairman of the Board and the Chief Executive Officer

         Frank P. Diassi has been Sterling's Chairman of the Board since August
21, 1996. Peter W. De Leeuw was Sterling's President and Chief Executive Officer
until May 8, 2000. In fiscal 2000, Mr. Diassi was paid a base salary of $350,016
and Mr. De Leeuw was paid a base salary at a rate of $325,000 per annum. We used
the same executive compensation practices described above to determine the
compensation paid to Messrs. Diassi and De Leeuw in fiscal 2000 and believe that
their fiscal 2000 base salaries were below the mid-point salary paid to similar
individuals in the competitive market. In fiscal 2000, neither Mr. Diassi nor
Mr. De Leeuw received any awards under the Omnibus Plan. Upon Mr. De Leeuw's
retirement, we paid a one-time payment to Mr. De Leeuw of $1,235,000 and $20,838
as compensation for unused vacation time.

Tax Treatment

         We consider the anticipated tax treatment of our executive compensation
program when setting levels and types of compensation. Section 162(m) of the
Internal Revenue Code generally disallows a tax deduction to public companies
for compensation paid to the company's chief executive officer or any of the
other four most highly compensated executive officers in excess of $1 million in
any year, with certain performance-based compensation being specifically exempt
from this deduction limit. In fiscal 2000, no employee of Sterling subject to
this limit received compensation in excess of $1 million. Consequently, we
believe that the requirements of Section 162(m) will not affect the tax
deductions available to Sterling in connection with its executive compensation
for the 2000 fiscal year.

Additional Information

         No portion of this report shall be deemed to be incorporated by
reference into any filing under the Securities Act or under the Securities
Exchange Act through any general statement incorporating by reference the Proxy
Statement in which this report appears in its entirety, except to the extent
that Sterling specifically incorporates this report or a portion of this report
by reference. In addition, this report shall not otherwise be deemed to be filed
under either of such Acts except the extent required by Item 402 of Regulation
S-K.

     *   The "value" of unexercised options is based on the amount, if any, by
         which the market price of a share of our common stock on the relevant
         date exceeds the exercise price of the option. The actual gain, if any,
         that one of our officers realizes from the exercise of options will
         depend on the market price of a share of our common stock at the time
         of exercise. An "In-The-Money" option is an option for which the
         exercise price is lower than the market price of a share of our common
         stock on the relevant date. None of our officers held options with an
         exercise price below the market price of a share of our common stock as
         of September 30, 2000.

                                       payable to an employee under this Plan
                                       are effectively limited in amount to
                                       those benefits that would be payable to
                                       an employee having Average Earnings of
                                       $170,000.

Pension Benefit                        Each of our salaried employees who is
  Equalization Plan                    eligible to participate in our Pension
                                       Plan is also eligible to participate in
                                       our Pension Benefit Equalization Plan.
                                       Our Equalization Plan pays additional
                                       benefits to employees whose benefits
                                       under our Pension Plan are limited as a
                                       result of specified limitations under the
                                       Internal Revenue Code. The amount of
                                       benefits payable under our Equalization
                                       Plan is designed to eliminate the effect
                                       of these limitations on the aggregate
                                       pension benefits payable to the
                                       participants but not provide any
                                       additional benefits beyond that amount.
                                       These benefits are generally payable at
                                       the times we pay benefits under our
                                       Pension Plan. We have paid benefits under
                                       our Equalization Plan to former
                                       employees.

Supplemental                           Each of our employees who are a part of
  Employee                             management or who are considered "highly
    Retirement Plan                    compensated" and subject to limitations
                                       on the amount of Pension Plan benefits

                                       participate in our Supplemental Employee
                                       Retirement Plan. Our Supplemental Plan
                                       pays additional benefits to employees
                                       whose benefits under our Pension Plan are
                                       limited as a result of such employee's
                                       Average Earnings exceeding $170,000 or
                                       due to the removal of certain Social
                                       Security integration benefits from the
                                       Pension Plan. The amount of benefits
                                       payable under our Supplemental Plan is
                                       designed to eliminate the effect of these
                                       limitations on the aggregate pension
                                       benefits payable to the participants but
                                       not provide any additional benefits
                                       beyond that amount. These benefits are
                                       generally payable at the same time as
                                       when we pay benefits under our Pension
                                       Plan. We have paid benefits under our
                                       Supplemental Plan to former employees.

         The following table sets forth the aggregate amount of annual normal
retirement benefits that would be payable under our Pension Plan, Equalization
Plan and Supplemental Plan if an employee retired during calendar 2000 at the
age of 65 with the years of service shown (assuming the continued existence of
our Pension Plan, Equalization Plan and Supplemental Plan without substantial
change and payment in the form of a single life annuity).

For our executive officers, the compensation covered by these Plans is solely
that compensation reported under the salary column in the executive compensation
table appearing in this Proxy Statement and may, as to a particular executive
officer for a given year, differ by more than 10% from that executive officer's
total annual compensation reported in the executive compensation table,
depending on the amount of bonuses and other annual compensation paid to that
executive officer during the relevant year.

         As of September 30, 2000, the credited years of service under these
Plans of each individual who served as our Chief Executive Officer or acted in a
similar capacity during fiscal 2000 and our other four most highly compensated
officers during fiscal 2000 were:

         All of the benefits appearing in the pension plan table are computed on
a single-life annuity basis and are not subject to any deduction for Social
Security or other offset amounts. However, our Supplemental Plan does contain an
alternative formula for determining benefits which includes a Social Security
offset. We have never used this alternative formula to determine the amount of
any benefits paid under our Supplemental Plan.

Employment Agreements

     GARY M. SPITZ

         On January 19, 1998, we entered into an Employment Agreement with Mr.
Spitz under which we engaged Mr. Spitz to serve as our Chief Financial Officer
and Vice President - Finance. Under his Employment Agreement, Mr. Spitz earns a
base salary that was initially set at $180,000 per year (subject to increase at
the discretion of our Board) and he participates in our bonus and incentive
plans. In addition, when Mr. Spitz signed his Employment Agreement, we paid Mr.
Spitz a $25,000 signing bonus and granted Mr. Spitz 5,000 shares of our common
stock (1,250 of which are currently subject to forfeiture if Mr. Spitz's
employment is terminated under specified circumstances) and options to purchase
45,000 shares of our common stock for $12 per share (with 20% of such options
vesting annually on each January 19, commencing with January 19, 1999). On
December 14, 1998, we reduced the exercise price of these options to $6 per
share. Mr. Spitz was also granted the right to purchase up to 50,000 shares of
our common stock but that right expired on April 30, 1998 without having been
exercised.

         Either we or Mr. Spitz may terminate Mr. Spitz's Employment Agreement
at any time, for any reason or for no reason. However, if Mr. Spitz terminates
his employment for a Good Reason (as defined in his Employment Agreement) after
the occurrence of a specified change of control or we terminate Mr. Spitz's
employment for any reason other than Misconduct or Disability (as those terms
are defined in his Employment Agreement), Mr. Spitz is entitled to continuing
coverage under all of our life, healthcare, medical and dental insurance plans
and programs (excluding disability) for 24 months, so long as Mr. Spitz pays any
required employee premiums under these plans or programs or COBRA. However, we
are not required to make these payments or provide these coverages if Mr.
Spitz's employment is terminated after his "normal retirement date" under our
Pension Plan and our obligation to provide continuing coverage under our
benefits plans immediately ends if Mr. Spitz obtains other employment where he
is provided with substantially similar benefits.

     DAVID G. ELKINS

         On November 12, 1997, we entered into an Employment Agreement with Mr.
Elkins under which we engaged Mr. Elkins to serve as our General Counsel and
Corporate Secretary and one of our Vice Presidents. Under his Employment
Agreement, Mr. Elkins earns a base salary that was initially set at $200,000 per
year (subject to increase at the discretion of our Board) and he participates in
our bonus and incentive plans. In addition, when Mr. Elkins signed his
Employment Agreement, we granted Mr. Elkins 5,000 shares of our common stock
(1,250 of which are currently subject to forfeiture if Mr. Elkins' employment is
terminated under specified circumstances) and options to purchase 60,000 shares
of our common stock for $12 per share (with 25% of such options vesting annually
on each January 1, commencing with January 1, 1999). On December 14, 1998, we
reduced the exercise price of these options to $6 per share. Mr. Elkins was also
granted the right to purchase up to 80,000 shares of our common stock but that
right expired on April 30, 1998 without having been exercised.


                                      -26-
<PAGE>   30

         Either we or Mr. Elkins may terminate Mr. Elkins' Employment Agreement
at any time, for any reason or for no reason. However, if Mr. Elkins terminates
his employment for a Good Reason (as defined in his Employment Agreement) or we
terminate Mr. Elkins' employment for any reason other than Misconduct or
Disability (as those terms are defined in his Employment Agreement), Mr. Elkins
is entitled to continuing coverage under all of our life, healthcare, medical
and dental insurance plans and programs (excluding disability) for 36 months, so
long as Mr. Elkins pays any required employee premiums under these plans or
programs or COBRA. However, we are not required to make these payments or
provide these coverages if Mr. Elkins' obtains other employment where he is
provided with substantially similar benefits. Finally, if Mr. Elkins' Employment
Agreement is terminated under these circumstances, all vesting and similar
requirements and all conditions to entitlement to benefits are deemed satisfied
under these plans and programs, meaning that all options held by Mr. Elkins
would immediately vest and all forfeiture provisions for any restricted stock
would immediately lapse.

         Under his Employment Agreement, Mr. Elkins is entitled to participate
in, and receive benefits under, most of our employee benefit plans as if his
employment with us commenced on January 1, 1993 or, in the case of our
post-retirement healthcare plan, January 1, 1988. In addition, Mr. Elkins is
entitled under his Employment Agreement to receive pension benefits which are
supplemental to the pension benefits payable to Mr. Elkins under our Pension
Plan, Equalization Plan and Supplemental Plan.

Severance Agreement

         On May 1, 2000, we entered into a Severance Agreement with Mr. De Leeuw
in connection with his retirement as our President and Chief Executive Officer,
which was effective as of May 8, 2000. Under the Severance Agreement, we paid
Mr. De Leeuw a lump sum amount for all unpaid base salary earned by Mr. De Leeuw
as of May 12, 2000, an additional lump sum payment of $20,837 as payment for
unused vacation time and an additional lump sum severance payment of $1,235,000.
We also paid Mr. De Leeuw $341,250 on October 26, 2000 as his prorated portion
of the bonus Mr. De Leeuw would have earned under our bonus plan had he remained
employed by us through that date. When we hired Mr. De Leeuw as our President
and Chief Executive Officer, we granted Mr. De Leeuw 10,000 shares of our common
stock subject to certain restrictions and options to acquire 125,000 shares of
our common stock subject to vesting over a five year period. Under the Severance
Agreement, Mr. De Leeuw became fully vested in all of such shares free of any
restrictions and all of these options. The Severance Agreement also contains
customary releases by us and Mr. De Leeuw and an agreement by Mr. De Leeuw to
not engage in specified competitive activities for a one-year period.

Key Employee Protection Plan

         On January 26, 2000, our Board approved our Key Employee Protection
Plan, which has subsequently been amended. Our Compensation Committee is
authorized to designate a select group of management or highly compensated
employees as participants under our Key Employee Protection Plan and set their
applicable multipliers. Our Compensation Committee may also terminate any
participant's participation under this Plan on 60 days' notice if it determines
that the participant is no longer one of our key employees.

         Under our Key Employee Protection Plan, any participant under the Plan
that terminates his or her employment for "Good Reason" or is terminated by us
for any reason other than "Misconduct" or "Disability" within two years after
the date on which a specified change of control occurs is entitled to benefits
under the Plan. If a participant becomes entitled to benefits under our Key
Employee Protection Plan, we are required to provide the participant with a lump
sum cash payment equal to the participant's


                                      -27-
<PAGE>   31

applicable multiplier times the sum of the participant's highest annual base
compensation during the last three years plus the participant's targeted bonus
for the year of termination. The amount of this payment is reduced, however, by
the amount of any other separation, severance or termination payments made by us
to the participant under any other plan or agreement or pursuant to law. In
addition, if the participant is not one of our senior executives, the
participant is not entitled to this amount if his or her termination date is
after his or her normal retirement date. The participant is also entitled to
receive any accrued but unpaid compensation, compensation for unused vacation
time and any unpaid vested benefits earned or accrued under any of our benefit
plans (other than qualified plans). Finally, for a period of 24 months
(including 18 months COBRA coverage), the participant will continue to be
covered by all of our life, health care, medical and dental insurance plans and
programs (other than disability), as long as the participant makes a timely
COBRA election and pays the regular employee premiums required under our plans
and programs and by COBRA. However, if the participant is not one of our senior
executives, the participant is not entitled to continued coverage under our
plans and programs if his or her termination date is after his or her normal
retirement date. In addition, our obligation to continue to provide coverage
under our plans and programs to any participant ceases if and when the
participant becomes employed on a full-time basis by a third party which
provides the participant with substantially similar benefits.

         If so approved by our Compensation Committee, any of our senior
executives can become entitled to receive all of the benefits provided under the
Plan, irrespective of whether a change of control has occurred. However, if
benefits are paid to a participant under this provision of the Plan, the senior
executive's applicable multiplier is reduced by 50%.

         If any payment or distribution under our Key Employee Protection Plan
to any participant is subject to excise tax pursuant to Section 4999 of the
Internal Revenue Code, the participant is entitled to receive a gross-up payment
from us in an amount such that, after payment by the participant of all taxes on
the gross-up payment, the amount of the gross-up payment remaining is equal to
the excise tax imposed under Section 4999 of the Internal Revenue Code. However,
the maximum amount of any gross-up payment is 25% of the sum of the
participant's highest annual base compensation during the last three years plus
the participant's targeted bonus for the year of payment.

         We may terminate our Key Employee Protection Plan at any time and for
any reason but any termination does not become effective as to any participant
until 90 days after we give the participant notice of the termination of the
Plan. In addition, we may amend our Key Employee Protection Plan at any time and
for any reason but any amendment that reduces, alters, suspends, impairs or
prejudices the rights or benefits of any participant in any material respect
does not become effective as to a participant until 90 days after we give the
participant notice of the amendment of the Plan. However, no termination of our
Key Employee Protection Plan, or any of these types of amendments to the Plan,
can be effective with respect to any participant if the termination or amendment
is related to, in anticipation of or during the pendency of a change of control
or is for the purpose of encouraging or facilitating a change of control. In
addition, no termination or amendment of our Key Employee Protection Plan can
affect the rights or benefits of any participant that are accrued under the Plan
at the time of termination or amendment or that accrue thereafter on account of
a change of control that occurred prior to the termination or amendment.

         In connection with our recapitalization in August of 1996, our common
stock was delisted from the New York Stock Exchange and is now included in the
OTC Electronic Bulletin Board maintained by the National Association of
Securities Dealers, Inc. We believe that this delisting, combined with the
contemporaneous significant reductions in the overall number of outstanding
shares and record holders of our common stock, have significantly reduced the
liquidity of the trading market for shares of our common stock.

         We cannot give you any assurance as to future trends in the cumulative
total return on shares of our common stock or of the following indices and we do
not make or endorse any predictions as to future stock performance.

terminates upon the earlier of (a) December 15, 2008 and (b) the later of (i)
the expiration of the Standby Purchase Agreement to which he is a party and (ii)
the time at which Mr. Cain beneficial owns less than 5% of our outstanding
shares.

         The holders of 8,753,243 shares of our common stock, representing
approximately 68% of our outstanding shares, are parties to a Stockholders
Agreement originally dated as of August 21, 1996 and a Tag-Along Agreement dated
as of August 21, 1996. The Stockholders Agreement restricts the transfer of
shares of our common stock held by the parties (with certain exceptions),
including any disposition of a control position, unless such shares are first
offered to be sold to our ESOP, then to us and then to the other parties to the
Stockholders Agreement. The Tag-Along Agreement provides that if any party to
the agreement, either by themselves or together with others, proposes to
transfer a total of 51% or more of our outstanding shares of common stock, that
party must give notice of the proposed transfer to each person that retained
shares of our common stock in our recapitalization conducted in August of 1996,
and each of these stockholders will have the right to have any shares they
retained in that recapitalization included in the transfer on a pro rata basis
and on the same terms and conditions.

         Since October 1, 1991, we have had ongoing commercial relationships in
the ordinary course of business with certain affiliates of Koch Industries,
Inc., including agreements for the supply of raw materials, sales of
petrochemicals and transportation of natural gas. During the fiscal year ended
September 30, 2000:

         o    we made product sales to and purchased raw materials from Koch
              Chemical and Koch Nitrogen Company, indirect wholly owned
              subsidiaries of Koch Industries;

         o    we made payments to John Zink Company, an indirect wholly owned
              subsidiary of Koch Industries, in consideration for certain
              contracting and construction services performed at our facilities
              in Texas City, Texas; and


                                      -33-
<PAGE>   37

         o    we made payments to Koch Gateway Pipeline Company for the
              transportation of natural gas to the our acrylic fiber plant
              through a pipeline in which it is a partner.

Each of these relationships represented less than 1% of our revenues, with the
exception that our raw material purchases from Koch Nitrogen and Koch Chemical
totaled around 3.3% of our revenues. In addition, in 1998 we filed a lawsuit
against John Zink Company seeking recovery for certain types of damages we
sustained in connection with a release of nickel carbonyl from our methanol unit
on July 30, 1997. This lawsuit has been voluntarily dismissed but, under a
tolling agreement between the parties, may be refiled at any time. Finally, in
May of 2000, we entered into a new 3-1/2 year ammonia supply agreement with Koch
Nitrogen. The new ammonia supply agreement replaced our prior ammonia supply
agreement with Koch Nitrogen which was not scheduled to expire until 2002. The
new ammonia supply agreement requires us to purchase the same annual quantity of
ammonia from Koch Nitrogen but at a revised pricing formula. In connection with
the execution of the new ammonia supply agreement, we made a payment to Koch
Nitrogen of $1.2 million to settle a dispute under the old ammonia supply
agreement and we also made a one-time payment to Koch Nitrogen of $1.8 million
in exchange for the revised pricing formula.

         As of December 15, 1998, we entered into separate Standby Purchase
Agreements with each of Messrs. Diassi and Hevrdejs, William A. McMinn (one of
our former directors), Gordon A. Cain, James Crane and Koch Capital Services,
Inc. Pursuant to the terms of these agreements, these parties committed to
purchase up to 2,500,000 shares of our common stock at a price of $6.00 per
share, if, as and when we request at any time prior to December 15, 2001. In
order to induce these parties to enter into the Standby Purchase Agreements, we
issued to them warrants to purchase an aggregate of 300,000 shares of our common
stock at an exercise price of $6.00 per share. In addition, under the Standby
Purchase Agreements, we agreed to issue to these parties additional warrants to
purchase up to 300,000 additional shares of our common stock if, as and when
they purchase shares of our common stock under these agreements. Any shares of
our common stock purchased under the Standby Purchase Agreements or on the
exercise of the warrants issued under the Standby Purchase Agreements will be
subject to the terms of the Voting Agreement, the Stockholders Agreement and the
Tag-Along Agreement described above.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires our
officers, directors and anyone who beneficially owns at least 10% of our common
stock to file reports regarding their ownership of our common stock and any
changes in that ownership with the SEC. We believe that, during fiscal 2000, our
officers, directors and 10% stockholders complied with all Section 16(a) filing
requirements. In making this statement we have relied on our review of copies of
these reports furnished to us and written representations from our officers and
directors.

                                   APPENDIX A

                     Audit and Compliance Committee Charter


                             PRELIMINARY STATEMENTS

              WHEREAS, the Board of Directors (the "Board") of Sterling
Chemicals Holdings, Inc. (the "Corporation") has heretofore established and
designated a standing committee of the Board known as the Audit and Compliance
Committee (the "Committee");

              WHEREAS, the Board has heretofore delegated oversight
responsibility to the Committee for the financial reporting, control and audit
functions of the Board and for compliance and monitoring programs, corporate
information and reporting systems and similar matters; and

              WHEREAS, the Board desires to adopt a formal written charter to
govern the composition, duties and responsibilities of the Committee;

              NOW, THEREFORE, IT IS HEREBY RESOLVED that this Audit and
Compliance Committee Charter (this "Charter") be, and it hereby is, adopted and
approved as the Charter of the Committee.

ROLE OF THE COMMITTEE

              The Committee shall act on behalf of the Board and oversee all
material aspects of the Corporation's financial reporting, control, audit and
compliance functions, except those reserved by the Board and those related to
the responsibilities of another standing committee of the Board. The Committee's
role includes a particular focus on the qualitative aspects of financial
reporting to the Corporation's stockholders, the Corporation's processes for the
management of financial risk and compliance with significant applicable legal,
ethical and regulatory requirements. The Committee shall review, discuss and
assess its own performance, as well as its role and responsibilities, and may
make recommendations to the Board regarding changes in the Committee's role or
responsibilities or this Charter. The Board shall review the adequacy of this
Charter at least once annually.

              While the Committee has the responsibilities and powers set forth
in this Charter, it is not the duty of the Committee to prepare financial
statements, to plan or conduct audits or to assure that the Corporation's
financial statements are complete and accurate or in accordance with generally
accepted accounting principles. Management is solely responsible for preparing
the financial statements and implementing internal controls and the
Corporation's external auditors are solely responsible for auditing the
financial statements and monitoring the effectiveness of the internal controls.
Nor is it the duty of the Committee to conduct investigations, to resolve
disagreements (if any) between management and the Corporation's external
auditors or to assure compliance with the Corporation's policies or any laws,
rules, regulations, permits or licenses.

COMPOSITION OF THE COMMITTEE

              The Committee shall consist of such number of directors (not less
than three) as the Board shall determine from time to time. Each member of the
Committee, including it chairman and any alternate members, shall be appointed
by the Board, shall serve at the pleasure of the Board and may be removed at any
time by the Board (with or without cause). Each Committee member shall (i) be


                                      A-i
<PAGE>   40


independent of management and free from any relationship that, in the opinion of
the Board, would interfere with the exercise of independent judgment as a member
of the Committee, (ii) have general knowledge of the primary industries in which
the Corporation operates, (iii) have the ability to read and understand
fundamental financial statements, including a balance sheet, income statement
and statement of cash flow and (iv) have the ability to understand key financial
risks and related controls and control processes. At least one member of the
Committee should be literate in business and financial reporting and control,
including knowledge of regulatory requirements, and should have past employment
experience in finance or accounting (or other comparable financial
sophistication or financial management expertise). No member of the Committee
may serve on the Compensation Committee of the Board at any time while such
member is a member of the Committee. The term of each member of the Committee
shall be determined in accordance with the Bylaws of the Corporation. The Board
shall have the power at any time to fill vacancies in, to change the membership
of or to dissolve the Committee.

COMMITTEE OPERATING PRINCIPLES

              The Committee shall fulfill its responsibilities within the
context of the following overriding principles:

              o     Working Relationships - The Committee should maintain
                    strong, positive working relationships with management,

                    attorneys.

              o     Communications and Coordination - The Committee should
                    strive to keep fully informed of current and prospective
                    issues facing the Corporation through, communications with
                    senior management, other standing committees of the Board
                    and key advisors, including internal and external auditors,
                    accountants and attorneys. In addition, the Committee should
                    strive to coordinate its compliance activities with the
                    Environmental, Health and Safety Committee of the
                    Corporation and the other standing committees of the Board.

              o     Education - The Committee should regularly review important
                    financial and operating topics that present potential
                    significant risk to the Corporation. Each member of the
                    Committee is encouraged to participate in relevant and
                    appropriate self-study education to assure understanding of
                    the business of the Corporation and its subsidiaries and the
                    environment in which they operate.

              o     Expectations and Information Needs - The Committee should
                    communicate its expectations and the nature, timing and
                    extent of information it requires to management and internal
                    and external auditors, accountants and attorneys. Written
                    materials, including key performance indicators and measures
                    related to key financial risks, should be provided to the
                    Committee by management at least one week in advance of any
                    meeting of the Committee at which such materials will be
                    discussed.

The Committee shall have direct access to the financial, legal and other staff
and advisors of the Corporation and shall have the authority, at the
Corporation's expense, to retain and consult with such professional advisors,
independent auditors and other experts in connection with the performance of its
duties and the exercise of its authority and powers.

MONITORING FINANCIAL REPORTING AND RELATED MATTERS

              Relationship With External Auditors. The external auditors of the
Corporation, in their capacity as independent public accountants, shall be
accountable to the Board and the Committee as representatives of the
stockholders. The Committee shall have primary responsibility for the

will be report to the Committee. In executing its oversight role with respect to
financial reporting and related matters, the Committee shall:

              o     make recommendations to the Board regarding the selection
                    and termination of the Corporation's external auditors;

              o     review and assess the nature and effect of any non-audit
                    services provided by the external auditors; and

              o     review and assess the external auditors' compensation and
                    the scope and proposed terms of their engagement, including
                    the range of audit and non-audit fees.

The Committee shall annually review the performance (effectiveness, objectivity
and independence) of the Corporation's internal and external auditors. The
Committee shall ensure receipt of a formal written statement from the external
auditors consistent with standards set by the Independence Standards Board.
Additionally, the Committee shall discuss with the auditor relationships or
services that may affect auditor objectivity or independence. If the Committee
is not satisfied with any external auditor's assurances of independence, it
shall take or recommend to the Board appropriate action to ensure the
independence of the external auditor.

              Financial Reporting and Controls. The Committee shall be charged
with the responsibility of reviewing the adequacy of the Corporation's financial
statements and financial reporting systems. In this regard, the Committee shall:

              o     review all major financial reports in advance of filings or
                    distributions;

              o     consider major changes and other questions of choice
                    regarding the appropriate auditing and accounting principles
                    and practices to be followed when preparing the
                    Corporation's financial statements, including major
                    financial statement issues and risks and their impact or
                    potential effect on reported financial information and the
                    scope, as well as the level of involvement by external
                    auditors in the preparation and review, of unaudited
                    quarterly or other interim-period information;

              o     review the annual audit plan and the process used to develop
                    the plan and monitor the status of activities;

              o     review the results of each external audit, including any
                    qualifications in the external auditor's opinion, any
                    related management letter, management's responses to
                    recommendations made by the external auditor in connection
                    with the audit and any reports submitted to the Committee by
                    internal auditors (if any) that are material to the
                    Corporation as a whole and management's responses to those
                    reports;

              o     discuss with the Corporation's external auditors (i) methods
                    used to account for significant unusual transactions, (ii)
                    the effect of significant accounting policies in


                                      A-iii
<PAGE>   42

                    controversial or emerging areas for which there is a lack of
                    authoritative guidance or consensus, (iii) the process used
                    by management in formulating particularly sensitive
                    accounting estimates and the basis for the auditor's
                    conclusion regarding reasonableness of such estimates and
                    (iv) disagreements with management over the application of
                    accounting principles, the basis for management's accounting
                    estimates and the disclosures in the financial statements;
                    and

              o     review the Corporation's annual and quarterly financial
                    statements and the views of management and the Corporation's
                    external auditors on the overall quality of the
                    Corporation's annual and interim financial reporting.

If any internal or external auditor of the Corporation identifies any
significant issue relative to overall Board responsibility that has been
communicated to management but, in their judgment, have not been adequately
addressed, they should communicate these issues to the chairman of the
Committee.

              Internal Financial Controls. The Committee shall review the
appointment and replacement of the senior internal-auditing executive of the
Corporation (if any) and any key financial management of the Corporation and
shall review the performance of the Corporation's internal auditors (if any).
The Corporation's internal auditors (if any) shall be responsible to the Board
through the Committee. The Committee shall consider, in consultation with the
Corporation's external auditors and the Corporation's senior internal-auditing
executive (if any), the adequacy of the Corporation's internal financial
controls. The Committee shall meet periodically with the senior
internal-auditing executive (if any) to discuss special problems or issues that
may have been encountered by the internal auditors (if any) and review the
implementation of any recommended corrective actions. The Committee shall also
meet periodically with senior management to review the Corporation's major
financial risk exposures.

              Communications With the Board. The Committee shall serve as a
channel of communication between the Corporation's external auditors and the
Board and between the Corporation's senior internal-auditing executive (if any)
and the Board.

              Regulatory Examinations. The Committee shall review and assess any
SEC inquiries and the results of examination by other regulatory authorities in
terms of important findings, recommendations and management's response.

COMPLIANCE MATTERS

              Compliance Programs and Procedures. In executing its oversight
role with respect to compliance functions, the Committee shall review the
adequacy of the Corporation's compliance and monitoring programs, corporate
information and reporting systems, codes of conduct, policies, standards,
practices and procedures (including compliance guides and manuals) for employees
of the Corporation and its subsidiaries. In addition, the Committee shall meet
periodically with senior management to discuss their views on whether:

              o     the operations of the Corporation and its subsidiaries are
                    conducted in compliance with all applicable laws, rules,
                    regulations, permits and licenses, including those
                    pertaining to environmental, health, safety, securities,
                    financial and employment matters;

              o     all accounting and reporting financial errors, fraud and
                    defalcations, legal violations and instances of
                    non-compliance with the Corporation's compliance and
                    monitoring


                                      A-iv

                    are detected;

                    to appropriate governmental officials when discovered and
                    prompt, voluntary remedial measures are instituted; and

              o     senior management and the Board are provided with timely,
                    accurate information to allow management and the Board to
                    reach informed judgments concerning the Corporation's
                    compliance with law and business performance.

              Compliance Officers. The Committee shall designate one or more
executives of the Corporation to be in charge of the Corporation's compliance
and monitoring programs, corporate information and reporting systems, codes of
conduct, policies, standards, practices and procedures, including the day-to-day

establish its own rules of procedure; provided, however, that such rules of
procedure are not inconsistent with the Certificate of Incorporation or Bylaws
of the Corporation or with any specific direction as to the conduct of its
affairs as shall have been given by the Board. The Committee shall keep regular
minutes of its proceedings and report the same to the Board when requested.

              Reporting to the Board. The Committee, through its chairman, shall

employees upon whom the responsibilities of the successful administration and
management of the Company and its Subsidiaries rest, and whose present and
potential contributions to the welfare of the Company and its Subsidiaries are
of importance, can acquire and maintain stock ownership, thereby strengthening
their concern for the welfare of the Company and its Subsidiaries and their
desire to remain in the Company's and its Subsidiaries' employ. A further
purpose of the Plan is to provide such employees with additional incentive and
reward opportunities designed to enhance the profitable growth of the Company
and its Subsidiaries. Accordingly, the Plan provides for granting Incentive
Stock Options, Nonqualified Stock Options, Stock Appreciation Rights, Restricted
Stock Awards, Performance Awards, Phantom Stock Awards, or any combination of
the foregoing, as is best suited to the circumstances of the particular employee
as provided herein.

              (b) Powers. Subject to the provisions of the Plan, the Committee
shall have sole authority, in its discretion, to determine which employees shall
receive an Award, the time or times when such Award shall be made, whether an
Incentive Stock Option, Nonqualified Option or Stock Appreciation Right shall be
granted, the number of shares of Stock which may be issued under each Option,

Committee may take into account the nature of the services rendered by the
respective employees, their present and potential contributions to the
Employer's success and such other factors as the Committee in its discretion
shall deem relevant.

              (c) Additional Powers. The Committee shall have such additional
powers as are delegated to it by the other provisions of the Plan. Subject to
the express provisions of the Plan, the Committee is authorized to construe the
Plan and the respective agreements executed thereunder, to prescribe such rules
and regulations relating to the Plan as it may deem advisable to carry out the
Plan, and to determine the terms, restrictions and provisions of each Award
including such terms, restrictions and provisions as

<PAGE>   49

shall be requisite in the judgment of the Committee to cause designated Options
to qualify as Incentive Stock Options, and to make all other determinations
necessary or advisable for administering the Plan. The Committee may correct any
defect or supply any omission or reconcile any inconsistency in any agreement
relating to an Award in the manner and to the extent it shall deem expedient to
carry it into effect. The determinations of the Committee on the matters
referred to in this Article IV shall be conclusive.

              (d) Expenses. All expenses and liabilities incurred by the
Committee in the administration of this Plan shall be borne by the Company. The
Committee may employ attorneys, consultants, accountants or other persons to
assist the Committee in the carrying out of its duties hereunder.

                          V. STOCK SUBJECT TO THE PLAN

              (a) Stock Grant and Award Limits. The Committee may from time to
time grant Awards to one or more employees determined by it to be eligible for
participation in the Plan in accordance with the provisions of Paragraph VI.
Subject to Paragraph XII, the aggregate number of shares of Stock that may be
issued under the Plan shall not exceed 2,000,000 shares. The shares subject to
this Plan shall consist of authorized but unissued shares of Stock or previously
issued shares of Stock reacquired and held by the Company, and such number of
shares shall be and is hereby reserved for such purpose. Shares of Stock shall
be deemed to have been issued under the Plan only to the extent actually issued
and delivered pursuant to an Award. To the extent that an Award lapses or the
rights of its Holder terminate or the Award is to only be paid in cash or is
paid in cash, any shares of Stock subject to such Award shall again be available
for the grant of an Award. To the extent that an Award lapses or the rights of
its Holder terminate, any shares of Stock subject to such Award shall again be
available for the grant of an Award. Separate stock certificates shall be issued
by the Company for those shares acquired pursuant to the exercise of an
Incentive Stock Option and for those shares acquired pursuant to the exercise of
a Nonqualified Stock Option.

              (b) Stock Offered. The stock to be offered pursuant to the grant
of an Award may be authorized but unissued Stock or Stock previously issued and
outstanding and reacquired by the Company.

                                 VI. ELIGIBILITY

              Awards may be granted only to persons who, at the time of grant,
are employees. Awards may not be granted to any Director who is not an employee.
An Award may be granted on more than one occasion to the same person, and,
subject to the limitations set forth in the Plan, such Award may include an
Incentive Stock Option or a Nonqualified Stock Option, a Stock Appreciation
Right, a Restricted Stock Award, a Performance Award, a Phantom Stock Award or
any combination thereof.

                               VII. STOCK OPTIONS

              (a) Option Period. The term of each Option shall be as specified
by the Committee at the date of grant.

              (b) Limitations on Exercise of Option. An Option shall be
exercisable in whole or in such installments and at such times as determined by
the Committee.

              (c) Special Limitations on Incentive Stock Options. To the extent
that the aggregate Fair Market Value (determined at the time the respective
Incentive Stock Option is granted) of Stock with


                                       B-v
<PAGE>   50

respect to which Incentive Stock Options are exercisable for the first time by
an employee during any calendar year under all incentive stock option plans of
the Company and its Affiliates exceeds $100,000, such Incentive Stock Options
shall be treated as Nonqualified Stock Options as determined by the Committee.
The Committee shall determine, in accordance with applicable provisions of the
Code, Treasury Regulations and other administrative pronouncements, which of an
Optionee's Incentive Stock Options will not constitute Incentive Stock Options
because of such limitation and shall notify the Optionee of such determination
as soon as practicable after such determination. No Incentive Stock Option shall
be granted to an employee if, at the time the Option is granted, such employee
owns stock possessing more than 10% of the total combined voting power of all
classes of stock of the Company or of its parent or subsidiary corporation,
within the meaning of section 422(b)(6) of the Code, unless (i) at the time such
Option is granted the option price is at least 110% of the Fair Market Value of
the Stock subject to the Option and (ii) such Option by its terms is not
exercisable after the expiration of five years from the date of grant.

              (d) Option Agreement. Each Option shall be evidenced by an Option
Agreement in such form and containing such provisions not inconsistent with the
provisions of the Plan as the Committee from time to time shall approve,
including, without limitation, provisions to qualify an Incentive Stock Option
under section 422 of the Code. An Option Agreement may provide for the payment
of the option price, in whole or in part, in cash or by the delivery of a number
of shares of Stock (plus cash if necessary) having a Fair Market Value equal to
such option price. Each Option shall specify the effect of termination of
employment on the exercisability of the Option; provided, that upon the death of
an Optionee, the Retirement of an Optionee, or upon the Optionee becoming
Disabled, all outstanding Options of such Optionee shall immediately vest and
become exercisable. Moreover, an Option Agreement may provide for a "cashless
exercise" of the Option by establishing procedures whereby the Holder, by a
properly-executed written notice, directs (i) an immediate market sale or margin
loan respecting all or a part of the shares of Stock to which he is entitled
upon exercise pursuant to an extension of credit by the Company to the Holder of
the option price, (ii) the delivery of the shares of Stock from the Company
directly to a brokerage firm and (iii) the delivery of the option price from the
sale or margin loan proceeds from the brokerage firm directly to the Company.
Such Option Agreement may also include, without limitation, provisions relating
to (i) vesting of Options, subject to the provisions hereof accelerating such
vesting upon the occurrence of an IPO or a Change of Control, (ii) tax matters
(including provisions (y) permitting the delivery of additional shares of Stock
or the withholding of shares of Stock from those acquired upon exercise to
satisfy federal or state income tax withholding requirements and (z) dealing
with any other applicable employee wage withholding requirements), and (iii) any
other matters not inconsistent with the terms and provisions of this Plan that
the Committee shall in its sole discretion determine. The terms and conditions
of the respective Option Agreements need not be identical.

              (e) Option Price and Payment. The price at which a share of Stock
may be purchased upon exercise of an Option shall be determined by the
Committee, but (i) such purchase price shall not be less than the Fair Market
Value of Stock subject to an Incentive Stock Option on the date the Incentive
Stock Option is granted and (ii) such purchase price shall be subject to
adjustment as provided in Paragraph XII. The Option or portion thereof may be
exercised by delivery of an irrevocable notice of exercise to the Company. The
purchase price of the Option or portion thereof shall be paid in full in the
manner prescribed by the Committee.

              (f) Stockholder Rights and Privileges. The Holder shall be
entitled to all the privileges and rights of a stockholder only with respect to
such shares of Stock as have been purchased under the Option and for which
certificates of stock have been registered in the Holder's name.


                                      B-vi
<PAGE>   51

              (g) Options and Rights in Substitution for Stock Options Granted
by Other Corporations. Options and Stock Appreciation Rights may be granted
under the Plan from time to time in substitution for stock options held by
individuals employed by corporations who become employees as a result of a
merger or consolidation of the employing corporation with the Company, an
Affiliate, or any Subsidiary, or the acquisition by the Company, an Affiliate or
a Subsidiary of the assets of the employing corporation, or the acquisition by
the Company, an Affiliate or a Subsidiary of stock of the employing corporation
with the result that such employing corporation becomes a Subsidiary.

                         VIII. STOCK APPRECIATION RIGHTS

              (a) Stock Appreciation Rights. A Stock Appreciation Right is the
right to receive an amount equal to the Spread with respect to a share of Stock
upon the exercise of such Stock Appreciation Right. Stock Appreciation Rights
may be granted in connection with the grant of an Option, in which case the
Option Agreement will provide that exercise of Stock Appreciation Rights will
result in the surrender of the right to purchase the shares under the Option as
to which the Stock Appreciation Rights were exercised. The Spread with respect
to a Stock Appreciation Right may be payable either in cash, shares of Stock
with a Fair Market Value equal to the Spread or in a combination of cash and
shares of Stock. With respect to Stock Appreciation Rights that are subject to
Section 16 of the 1934 Act, however, the Committee shall, except as provided in
Paragraph XII(c), retain sole discretion (i) to determine the form in which
payment of the Stock Appreciation Right will be made (i.e., cash, securities or
any combination thereof) or (ii) to approve an election by a Holder to receive
cash in full or partial settlement of Stock Appreciation Rights.

              (b) Stock Appreciation Rights Agreement. Stock Appreciation Rights
granted independently of Options shall be evidenced by a Stock Appreciation
Rights Agreement. Each Stock Appreciation Rights Agreement shall specify the
effect of termination of employment on the exercisability of the Stock
Appreciation Rights; provided, that upon the death of a Holder of a Stock
Appreciation Right, the Retirement of such Holder, or upon such Holder becoming
Disabled, all outstanding Stock Appreciation Rights of such Holder shall
immediately vest and become exercisable. Stock Appreciation Rights Agreements
may also include, without limitation, provisions relating to (i) vesting of
Awards, subject to the provisions hereof accelerating vesting upon the
occurrence of an IPO or a Change of Control, (ii) tax matters (including
provisions covering applicable wage withholding requirements), and (iii) any
other matters not inconsistent with the terms and provisions of this Plan, that
the Committee shall in its sole discretion determine. The terms and conditions
of the respective Stock Appreciation Rights Agreements need not be identical.

              (c) Exercise Price. The exercise price of each Stock Appreciation
Right shall be determined by the Committee in its sole discretion and shall be
subject to adjustment as provided in Paragraph XII.

              (d) Exercise Period. The term of each Stock Appreciation Right
shall be as specified by the Committee at the date of grant.

              (e) Limitations on Exercise of Stock Appreciation Right. A Stock
Appreciation Right shall be exercisable in whole or in such installments and at
such times as determined by the Committee.

                           IX. RESTRICTED STOCK AWARDS

              (a) Restricted Stock Awards. A Restricted Stock Award shall be
represented by a certificate of Stock registered in the name of the Holder of
such Restricted Stock Award. The Holder


                                      B-vii
<PAGE>   52

shall have the right to receive dividends with respect to Stock subject to a
Restricted Stock Award, to vote Stock subject thereto and to enjoy all other
stockholder rights, except that (i) the Holder shall not be entitled to delivery
of the Stock certificate until the Forfeiture Restrictions shall have expired,
(ii) the Company shall retain custody of the Stock until the Forfeiture
Restrictions shall have expired, (iii) the Holder may not sell, transfer,
pledge, exchange, hypothecate or otherwise dispose of the Stock until the
Forfeiture Restrictions shall have expired, and (iv) a breach of the terms and
conditions established by the Committee pursuant to the Restricted Stock
Agreement shall cause a forfeiture of the Restricted Stock Award.

              (b) Forfeiture Restrictions to be Established by the Committee.
The Forfeiture Restrictions on shares of Stock that are the subject of a
Restricted Stock Award shall be determined by the Committee in its sole
discretion, and the Committee may provide that the Forfeiture Restrictions shall
lapse upon (i) the attainment of targets established by the Committee that are
based on (1) the price of a share of Stock, (2) the Company's earnings per
share, (3) the Company's revenue, (4) the revenue of a business unit of the
Company designated by the Committee, (5) the return on stockholders' equity
achieved by the Company, or (6) the Company's pre-tax cash flow from operations,
(ii) the Holder's continued employment with the Employer for a specified period
of time, or (iii) a combination of any two or more of the factors listed in
clauses (i) and (ii) of this sentence. Each Restricted Stock Award may have
different Forfeiture Restrictions, in the discretion of the Committee. The
Forfeiture Restrictions applicable to a particular Restricted Stock Award shall
not be changed except as permitted by Paragraph IX(b) or Paragraph XII.

              (c) Other Terms and Conditions. At the time of a Restricted Stock
Award, the Committee may, in its sole discretion, prescribe additional terms,
conditions or restrictions relating to Restricted Stock Awards, including, but
not limited to, rules pertaining to the termination of employment of a Holder
prior to expiration of the Forfeiture Restrictions; provided, that upon the
death of a Holder of a Restricted Stock Award, the Retirement of such Holder, or
upon such Holder becoming Disabled, all Forfeiture Restrictions applicable to
all Restricted Stock Awards of such Holder shall lapse and expire. Such
additional terms, conditions or restrictions shall be set forth in a Restricted
Stock Agreement made in conjunction with the Award. Such Restricted Stock
Agreement may also include, without limitation, provisions relating to (i)
subject to the provisions hereof accelerating vesting upon the occurrence of an
IPO or a Change of Control, vesting of Awards, (ii) tax matters (including
provisions (y) covering any applicable employee wage withholding requirements
and (z) prohibiting an election by the Holder under section 83(b) of the Code),
and (iii) any other matters not inconsistent with the terms and provisions of
this Plan that the Committee shall in its sole discretion determine. The terms
and conditions of the respective Restricted Stock Agreements need not be
identical.

              (d) Payment for Restricted Stock. The Committee shall determine
the amount and form of any payment for Stock received pursuant to a Restricted
Stock Award, provided that in the absence of such a determination, a Holder
shall not be required to make any payment for Stock received pursuant to a
Restricted Stock Award, except to the extent otherwise required by law.

              (e) Agreements. At the time any Award is made under this Paragraph
IX, the Company and the Holder shall enter into a Restricted Stock Agreement
setting forth each of the matters as the Committee may determine to be
appropriate. The terms and provisions of the respective Restricted Stock
Agreements need not be identical.

                              X. PERFORMANCE AWARDS

              (a) Performance Period. The Committee shall establish, with
respect to and at the time of each Performance Award, a performance period over
which the performance of the Holder shall be measured.

              (b) Performance Awards. Each Performance Award shall have a
maximum value established by the Committee at the time of such Award.

              (c) Performance Measures. A Performance Award shall be awarded to
an employee contingent upon future performance of the employee, the Company, an
Affiliate, any Subsidiary, or any division or department thereof by or in which
he is employed during the performance period. The Committee shall establish the
performance measures applicable to such performance prior to the beginning of
the performance period but subject to such later revisions as the Committee
shall deem appropriate to reflect significant, unforeseen events or changes.

              (d) Awards Criteria. In determining the value of Performance
Awards, the Committee shall take into account an employee's responsibility
level, performance, potential, other Awards and such other considerations as it
deems appropriate.

              (e) Payment. Following the end of the performance period, the
Holder of a Performance Award shall be entitled to receive payment of an amount,
not exceeding the maximum value of the Performance Award, based on the
achievement of the performance measures for such performance period, as
determined by the Committee. Payment of a Performance Award may be made in cash,
Stock or a combination thereof, as determined by the Committee. Payment shall be
made in a lump sum or in installments as prescribed by the Committee. Any
payment to be made in Stock shall be based on the Fair Market Value of the Stock
on the payment date. If a payment of cash is to be made on a deferred basis, the
Committee shall establish whether interest shall be credited, the rate thereof
and any other terms and conditions applicable thereto.

              (f) Termination of Employment. A Performance Award shall terminate
if the Holder does not remain continuously in the employ of the Employer at all
times during the applicable performance period, except as maybe determined by
the Committee or as may otherwise be provided in the Award at the time granted.

              (g) Agreements. At the time any Award is made under this Paragraph
X, the Company and the Holder shall enter into a Performance Stock Award
Agreement setting forth each of the matters contemplated hereby, and, in
addition such matters are set forth in Paragraph IX(b) as the Committee may
determine to be appropriate. The terms and provisions of the respective
agreements need not be identical.

                            XI. PHANTOM STOCK AWARDS

              (a) Phantom Stock Awards. Phantom Stock Awards are rights to
receive shares of Stock (or cash in an amount equal to the Fair Market Value
thereof), or rights to receive an amount equal to any appreciation in the Fair
Market Value of Stock (or portion thereof) over a specified period of time,
which vest over a period of time (subject to the provisions hereof accelerating
vesting upon the occurrence of an IPO or a Change of Control) as established by
the Committee, without payment of any amounts by the Holder thereof (except to
the extent otherwise required by law) or satisfaction of any performance


                                      B-ix
<PAGE>   54

criteria or objectives. Each Phantom Stock Award shall have a maximum value
established by the Committee at the time of such Award.

              (b) Award Period. The Committee shall establish, with respect to
and at the time of each Phantom Stock Award, a period over which or the event
upon which the Award shall vest with respect to the Holder.

              (c) Awards Criteria. In determining the value of Phantom Stock
Awards, the Committee shall take into account an employee's responsibility
level, performance, potential, other Awards and such other considerations as it
deems appropriate.

              (d) Payment. Following the end of the vesting period for a Phantom
Stock Award, the Holder of a Phantom Stock Award shall be entitled to receive
payment of an amount, not exceeding the maximum value of the Phantom Stock
Award, based on the then vested value of the Award. Payment of a Phantom Stock
Award may be made in cash, Stock or a combination thereof as determined by the
Committee. Payment shall be made in a lump sum or in installments as prescribed
by the Committee in its sole discretion. Any payment to be made in Stock shall
be based on the Fair Market Value of the Stock on the payment date. Cash
dividend equivalents may be paid during or after the vesting period with respect
to a Phantom Stock Award, as determined by the Committee. If a payment of cash
is to be made on a deferred basis, the Committee shall establish whether
interest shall be credited, the rate thereof and any other terms and conditions
applicable thereto.

              (e) Termination of Employment. Except as may be otherwise
determined by the Committee or as set forth in the Award at the time of grant, a
Phantom Stock Award shall terminate if the Holder does not remain continuously
in the employ of the Employer at all times during the applicable vesting period;
provided, however, that upon the death of a Holder of a Phantom Stock Award, the
Retirement of such Holder, or upon such Holder becoming Disabled, all
outstanding Phantom Stock Awards of such Holder shall immediately vest and
become distributable.

              (f) Agreements. At the time any Award is made under this Paragraph
XI, the Company and the Holder shall enter into a Phantom Stock Award Agreement
setting forth each of the matters contemplated hereby and, in addition, such
matters as are set forth in Paragraph IX(b) as the Committee may determine to be
appropriate. The terms and provisions of the respective agreements need not be
identical.

                     XII. RECAPITALIZATION OR REORGANIZATION

              (a) The shares with respect to which Awards may be granted are
shares of Stock as presently constituted, but if, and whenever, prior to the
expiration of an Award theretofore granted, the Company shall effect a
subdivision or consolidation of such shares of Stock or other capital
readjustment, the number of shares of Stock with respect to which such Award may
thereafter be exercised or satisfied, as applicable, (i) in the event of an
increase in the number of outstanding shares shall be proportionately increased,
and the purchase price per share shall be proportionately reduced, and (ii) in
the event of a reduction in the number of outstanding shares shall be
proportionately reduced, and the purchase price per share shall be
proportionately increased.

              (b) If the Company recapitalizes or otherwise changes its capital
structure, thereafter upon any exercise or satisfaction, as applicable, of an
Award theretofore granted the Holder shall be entitled to (or entitled to
purchase, if applicable) under such Award, in lieu of the number of shares of
Stock then covered by such Award, the number and class of shares of stock and
securities to which the Holder


                                       B-x
<PAGE>   55

would have been entitled pursuant to the terms of the recapitalization if,
immediately prior to such recapitalization, the Holder had been the holder of
record of the number of shares of Stock then covered by such Award.

              (c) In the event of an IPO or a Change of Control, all outstanding
Awards shall immediately vest and become exercisable or satisfiable, as
applicable. The Committee, in its discretion, may determine that upon the
occurrence of a Change of Control, each Award other than an Option outstanding
hereunder shall terminate within a specified reasonable number of days after
notice to the Holder, and such Holder shall receive, with respect to each share
of Stock subject to such Award, cash in an amount equal to the excess, if any,
of the Change of Control Value over any exercise price or purchase price paid,
if applicable. Further, in the event of a Change of Control, the Committee, in
its discretion shall act to effect one or more of the following alternatives
with respect to outstanding Options, which may vary among individual Holders and
which may vary among Options held by any individual Holder: (i) determine a
reasonable period of time on or before a specified date (before or after such
Change of Control) after which specified date all unexercised Options and all
rights of Holders thereunder shall terminate, (2) require the mandatory
surrender to the Company by selected Holders of some or all of the outstanding
Options held by such Holders (irrespective of whether such Options are then
exercisable under the provisions of the Plan) as of a date, before or after such
Change of Control, specified by the Committee, in which event the Committee
shall thereupon cancel such Options and the Company shall pay to each Holder an
amount of cash per share equal to the excess, if any, of the Change of Control
Value of the shares subject to such Option over the exercise price(s) under such
Options for such shares, or (3) provide that thereafter upon any exercise of an
Option theretofore, granted the Holder shall been titled to purchase under such
Option, in lieu of the number of shares of Stock then covered by such Option,
the number and class of shares of stock or other securities or property
(including, without limitation, cash) to which the Holder would have been
entitled pursuant to the terms of the agreement of merger, consolidation or sale
of assets and dissolution if, immediately prior to such merger, consolidation or
sale of assets and dissolution the Holder has been the holder of record of the
number of shares of Stock then covered by such Option. The provisions contained
in this paragraph shall not terminate any rights of the Holder to further
payments pursuant to any other agreement with the Company following a Change of
Control.

              (d) In the event of changes in the outstanding Stock by reason of
recapitalization, reorganizations, mergers, consolidations, combinations,
exchanges or other relevant changes in capitalization occurring after the date
of the grant of any Award and not otherwise provided for by this Paragraph XII,
any outstanding Awards and any agreements evidencing such Awards shall be
subject to adjustment by the Committee at its reasonable discretion as to the
number and price of shares of Stock or other consideration subject to such
Awards. In the event of any such change in the outstanding Stock, the aggregate
number of shares available under the Plan may be appropriately adjusted by the
Committee, whose determination shall be reasonable and conclusive.

              (e) The existence of the Plan and the Awards granted hereunder
shall not affect in any way the right or power of the Board or the stockholders
of the Company to make or authorize any adjustment, recapitalization,
reorganization or other change in the Company's capital structure or its
business, any merger or consolidation of the Company, any issue of debt or
equity securities ahead of or affecting Stock or the rights thereof, the
dissolution or liquidation of the Company or any sale, lease, exchange or other
disposition of all or any part of its assets or business or any other corporate
act or proceeding.

              (f) Any adjustment provided for in Subparagraphs (a), (b), (c) or
(d) above shall be subject to any required stockholder action.


                                      B-xi
<PAGE>   56

              (g) Except as herein before expressly provided, the issuance by
the Company of shares of stock of any class or securities convertible into
shares of stock of any class, for cash, property, labor or services, upon direct
sale, upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares of obligations of the Company convertible into such shares
or other securities, and in any case whether or not for fair value, shall not
affect, and no adjustment by reason thereof shall be made with respect to, the
number of shares of Stock subject to Awards theretofore granted or the purchase
price per share, if applicable.

                   XIII. AMENDMENT AND TERMINATION OF THE PLAN

              The Board, in its discretion, may at any time or times amend,
suspend or terminate the Plan; provided, however, such action shall be subject
to the approval of the stockholders of the Company where stockholder approval
(i) is required by applicable law or (ii) the Board determines (A) such approval
is necessary to comply with any requirements of any securities exchange on which
the stock is listed or (B) such approval is desired for any other reason;
provided, further, however, that no amendment, suspension or termination of the
Plan may, without the consent of the holder of an Award, terminate such Award or
adversely affect such person's rights in any material respect.

                               XIV. MISCELLANEOUS

              (a) No Right to An Award. Neither the adoption of the Plan by the
Company nor any action of the Board or the Committee shall be deemed to give an
employee any right to be granted an Award to purchase Stock, a right to a Stock
Appreciation Right, a Restricted Stock Award, a Performance Award or a Phantom
Stock Award or any of the rights hereunder except as may be evidenced by an
Award or by an Option Agreement, Stock Appreciation Rights Agreement, Restricted
Stock Agreement, Performance Award Agreement or Phantom Stock Award Agreement on
behalf of the Company, and then only to the extent and on the terms and
conditions expressly set forth therein. The Plan shall be unfunded. The Company
shall not be required to establish any special or separate fund or to make any
other segregation of funds or assets to assure the payment of any Award.

              (b) Employees' Rights Unsecured. The right of an employee to
receive Stock, cash or any other payment under this Plan shall be an unsecured
claim against the general assets of the Company. The Company may, but shall not
be obligated to, acquire shares of Stock from time to time in anticipation of
its obligations under this Plan, but a Participant shall have no right in or
against any shares of Stock so acquired. All Stock shall constitute the general
assets of the Company and may be disposed of by the Company at such time and for
such purposes as it deems appropriate.

              (c) Agreement Controls. No discretionary action by the Committee
as set forth herein shall amend or supersede the express terms of any Agreement.

              (d) No Employment Rights Conferred. Nothing contained in the Plan
shall (i) confer upon any employee any right with respect to continuation of
employment with any Employer or (ii) interfere in any way with the right of any
Employer to terminate an employee's employment at any time.

              (e) Other Laws; Withholding. The Company shall not be obligated to
issue any Stock pursuant to any Award granted under the Plan at any time when
the shares covered by such Award have not been registered under the Securities
Act of 1933 and such other state and federal laws, rules or regulations as the
Company or the Committee deems applicable and, in the opinion of legal counsel
for the Company, there is no exemption from the registration requirements of
such laws, rules or regulations available for the issuance and sale of such
shares. Unless the Awards and Stock covered by this Plan


                                      B-xii
<PAGE>   57

have been registered under the Securities Act of 1933, or the Company has
determined that such registration is unnecessary, each Holder exercising an
Award under this Plan may be required by the Company to give representation in
writing that such Holder is acquiring such shares for his or her own account for
investment and not with a view to, or for sale in connection with, the
distribution of any part thereof. No fractional shares of Stock shall be
delivered, nor shall any cash in lieu of fractional shares be paid. The Company
shall have the right to deduct in connection with all Awards any taxes required
by law to be withheld and to require any payments required to enable it to
satisfy its withholding obligations.

              (f) No Restriction on Corporate Action. Nothing contained in the
Plan shall be construed to prevent the Company, an Affiliate or any Subsidiary
from taking any corporate action which is deemed by the Company, an Affiliate or
any Subsidiary to be appropriate or in its best interest, whether or not such
action would have an adverse effect on the Plan or any Award made under the
Plan. No employee, beneficiary or other person shall have any claim against the
Company, an Affiliate or any Subsidiary as a result of any such action.

              (g) Restrictions on Transfer. Except as provided below, an Award
shall not be transferable otherwise than by will or the laws of descent and
distribution and shall be exercisable during the Holder's lifetime only by such
Holder or the Holder's guardian or legal representative. However, the Committee
may, in its discretion, provide in an option agreement (other than with respect
to an Incentive Stock Option) that the option right granted to the individual
may be transferred (in whole or in part and shall be subject to such terms and
conditions as the Committee may impose thereon, including, without limitation,
the approval by the Company of the form of transfer agreement) by the individual
to (i) the spouse, children or grandchildren of the individual ("Immediate
Family Members"), (ii) a trust or trusts for the exclusive benefit of the
Immediate Family Members and, if applicable, the individual, (iii) a partnership
in which such Immediate Family Members and, if applicable, the individual are
the only partners, or (iv) any other person or entity otherwise permitted by the
Committee. Following transfer, any such transferred option rights shall continue
to be subject to the same terms and conditions as were applicable to the option
rights immediately prior to transfer; provided, however, that no transferred
option rights shall be exercisable unless arrangements satisfactory to the
Company have been made to satisfy any tax withholding obligations the Company
may have with respect to the option rights.

              (h) Beneficiary Designation. Each Holder may name, from time to
time, any beneficiary or beneficiaries (who may be named contingently or
successively) to whom any benefit under the Plan is to be paid in case of his or
her death before he or she receives any or all of such benefit. Each designation
will revoke all prior designations by the same Holder, shall be in a form
prescribed by the Committee, and will be effective only when filed by the Holder
in writing with the Committee during his lifetime. In the absence of any such
designation, benefits remaining unpaid at the Holder's death shall be paid to
his estate.

              (i) Rule 16b-3. It is intended that the Plan and any grant of an
Award made to a person subject to Section 16 of the 1934 Act meet all of the
requirements of Rule 16b-3. If any provision of the Plan or any such Award would
disqualify the Plan or such Award under, or would otherwise not comply with,
Rule 16b-3, such provision or Award shall be construed or deemed amended to
conform to Rule 16b-3.

              (j) Section 162(m). If the Plan is subject to Section 162(m) of
the Code, it is intended that the Plan comply fully with and meet all the
requirements of Section 162(m) of the Code so that Options and Stock
Appreciation Rights granted hereunder and, if determined by the Committee,
Restricted Stock Awards, shall constitute "performance-based" compensation
within the meaning of such section. If any


                                     B-xiii
<PAGE>   58

provision of the Plan would disqualify the Plan or would not otherwise permit
the Plan to comply with Section 162(m) as so intended, such provision shall be
construed or deemed amended to conform to the requirements or provisions of
Section 162(m);provided that no such construction or amendment shall have an
adverse effect on the economic value to a Holder of any Award previously granted
hereunder.

              (k) Indemnification. Each person who is or shall have been a
member of the Committee or of the Board and any employee delegated authority
hereunder shall be indemnified and held harmless by the Company against and from
any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by him in connection with or resulting from any claim, action, suit, or
proceeding to which he may be a party or in which he may be involved by reason
of any action taken or failure to act under the Plan and against and from any
and all amounts paid by him in settlement thereof, with the Company's approval,
or paid by him in satisfaction of any judgment in any such action, suit, or
proceeding against him, provided he shall give the Company prompt written notice
of any such action, suit or proceeding, and an opportunity, at its own expense,
to handle, defend and/or settle the same before he undertakes to handle, defend
and/or settle it on his own behalf. The foregoing right of indemnification shall
not be exclusive of any other rights or indemnification to which such persons
may be entitled under the Company's Articles of Incorporation or Bylaws, as a
matter of law, or otherwise, or any power that the Company may have to indemnify
them or hold them harmless.

              (l) Governing Law. This Plan shall be construed in accordance with
the laws of the State of Delaware and applicable federal law.

              IN WITNESS WHEREOF, Sterling Chemicals Holdings, Inc. has caused
this document to be duly executed in its name and behalf by its proper officer
thereunto duly authorized, effective for all purposes as of the date of the
adoption of the Plan by the Board, being April 23, 1997.
