     voting securities of such corporation (entitled to vote generally in the
     election of directors), are beneficially owned, directly or indirectly, by
     all or substantially all of the individuals and entities who, immediately
     prior to such acquisition, were the beneficial owners of the then

     of the then outstanding common stock and voting securities (entitled to
     vote generally in the election of directors) of the corporation resulting
     from such reorganization, merger or consolidation in substantially the same
     proportions as their respective ownership, immediately prior to such
     reorganization, merger or consolidation, of the Common Stock and Voting
     Securities; or

               1.4.3. The occurrence after the Effective Date of (a) a complete
     liquidation or substantial dissolution of the Company, or (b) the sale or
     other disposition of all or substantially all of the assets of the Company,

medical physician, each shall appoint one medical physician and those two
physicians shall appoint a third physician who shall make such determination. In

"Company's Successor" (as defined in Section 8.2 below) to expressly assume this
Agreement in writing, and all of the duties and obligations of the Company
hereunder in accordance with Section 8.2.

Agreement and specifically as provided in Section 4.1, the Company hereby agrees
that the Executive shall during the "Term of Employment" (as defined in Section

thereafter unless, not later than 180 days prior to any such anniversary, either
party to this Agreement shall have given notice to the other that the Term of
Employment shall not be extended or further extended beyond its then

the Code, or any successor or like provision, with respect to any payment or

and/or any Affiliate and for which the Executive may qualify, nor shall anything
herein limit or otherwise prejudice such rights as the Executive may have under
any other existing or future agreements with the Company and/or any Affiliate,

which are vested benefits or which the Executive is otherwise entitled to
receive under any plans or programs of the Company and/or any Affiliate at or

obligation to establish or maintain any such plan, policy or program.

     8.   Successors.

          8.1. The Executive. This Agreement is personal to the Executive and,
without the prior express written consent of the Company, shall not be
assignable by the Executive, except that the Executive's rights to receive any
compensation or benefits under this Agreement may be transferred or disposed of
pursuant to testamentary disposition, intestate succession or pursuant to a
domestic relations order. This Agreement shall inure to the benefit of and be
enforceable by the Executive's heirs, beneficiaries and/or legal
representatives.

          8.2. The Company. This Agreement shall inure to the benefit of and be

assets, whether direct or indirect, by purchase, merger, consolidation,
acquisition of stock, or otherwise (the "Company's Successor"), by an agreement
in form and substance satisfactory to the Executive, expressly to assume and
agree to perform this Agreement in the same manner and to the same extent as the
Company would be required to perform if no such succession had taken place.

     9.   Restrictive Covenants.

          9.1. Non-Solicitation. If the Executive's employment with the Company
terminates for any reason, the Executive, for the greater of twelve months after

he has incurred a termination of service under Section 6.4), shall not (except
on the Company's behalf), directly or indirectly, on his own behalf or on behalf
of any other person, firm, partnership, corporation or other entity, (a) solicit
or service the business of any of the Company's or its Affiliates' clients, any
of the Company's or its Affiliates' former clients which were clients within
twelve months prior to the termination of his employment or any of the
prospective clients which were being actively solicited by the Company or its
Affiliates at the time of the termination of his employment or (b) attempt to
cause or induce any employee of the Company or its Affiliates to leave the
Company or the Affiliate.

          9.2. Non-Competition. If the Executive's employment with the Company
terminates for any reason, except by non-renewal of this Agreement by the
Company for reason other than for Cause, the Executive, for the greater of
twelve months after any such termination or the period during which the
Executive receives Base Salary continuation after any such termination (for
these purposes, the Executive shall be deemed to receive Base Salary
continuation for three years if he has incurred a termination of service under
Section 6.4), shall not, directly or indirectly, within or with respect to the
United States of America engage, without the consent of the Company, in any
business or activity, whether as an employee, consultant, partner, principal,
agent, representative, stockholder or in any other capacity, or render any
services or provide any advice to any business, activity, person or entity which
competes with any PET packaging business; provided, however, that the
Executive's ownership of not more than 5% of the stock of any publicly-traded
corporation shall not be a violation of this Section 9.2. The Executive
acknowledges that his skills are such that he can be gainfully employed in
noncompetitive employment and that the agreement not to compete will in no way
prevent him from earning a living. The Executive understands and agrees that the
rights and obligations set forth in this Section 9.2 shall extend beyond the
Term of Employment.

          9.3. Confidentiality. The Executive shall not, during the Term of
Employment and at any time thereafter, without the prior express written consent
of the Company, directly or indirectly divulge, disclose or make available or
accessible any Confidential Information (as defined below) to any person, firm,
partnership, corporation, trust or any other entity or third party (other than
when required to do so in good faith to perform the Executive's duties and
responsibilities under this Agreement or when (a) required to do so by a lawful
order of a court of competent jurisdiction, any governmental authority or
agency, or any recognized subpoena power, or (b) necessary to prosecute the
Executive's rights against the Company or its Affiliates' or to defend himself
against any allegations). In addition, the Executive shall not create any
derivative work or other product based on or resulting from any Confidential
Information (except in the good faith performance of his duties under this
Agreement). The Executive shall also proffer to the Board's designee, no later
than the effective date of any termination of his employment with the Company
for any reason, and without retaining any copies, notes or excerpts thereof, all
memoranda, computer disks or other media, computer programs, diaries, notes,
records, data, customer or client lists, marketing plans and strategies, and any
other documents consisting of or containing Confidential Information that are in
the Executive's actual or constructive possession or which are subject to his
control at such time. For purposes of this Agreement, "Confidential Information"
shall mean all information respecting the business and activities of the
Company, or any Affiliate of the Company, including, without limitation, the
terms and provisions of this Agreement, the clients, customers, suppliers,
employees, consultants, computer or other files, projects, products, computer
disks or other media, computer hardware or computer software programs, marketing
plans, financial information, methodologies, know-how, processes, practices,
approaches, projections, forecasts, formats, systems, data gathering methods
and/or strategies of the Company or any Affiliate. Notwithstanding the
immediately preceding sentence, Confidential Information shall not include any
information that is, or becomes, generally available to the public (unless such
availability occurs as a result of the Executive's breach of any portion of this
Section 9.3).

          9.4. Ownership of Inventions. Each Invention (as defined below) made,
conceived or first actually reduced to practice by the Executive, whether alone
or jointly with

                                        9

others, during the term of Executive's employment with the Company and each
Invention made, conceived or first actually reduced to practice by the
Executive, whether alone or jointly with others, within one year after the
termination of Executive's employment with the Company which relates in any way
to work performed for the Company during the term of Executive's employment,
shall be promptly disclosed in writing to the Board. Such report shall be
sufficiently complete in technical detail and appropriately illustrated by
sketch or diagram to convey to one skilled in the art of which the invention
pertains, a clear understanding of the nature, purpose, operations, and, to the
extent known, the physical, chemical, biological or other characteristics of the
Invention. As used in this Agreement, "Invention" means any invention, discovery
or innovation with regard to any facet of the Company's business whether or not
patentable, made, conceived, or first actually reduced to practice by Executive,
alone or jointly with others, in the course of, in connection with, or as a
result of service as an employee of the Company, including any art, method,
process, machine, manufacture, design or composition of matter, or any
improvement thereof. Each Invention, as herein defined, shall be the sole and
exclusive property of the Company. The Executive agrees to execute an assignment
to the Company or its nominee of the Executive's entire right, title and
interest in and to any Invention, without compensation beyond that provided in
this Agreement. The Executive further agrees, upon the request of the Company
and at its expense, that the Executive will execute any other instrument and
document necessary or desirable in applying for and obtaining patents in the
United States and in any foreign country with respect to any Invention. The
Executive further agrees, whether or not the Executive is then an employee of
the Company, to cooperate to the extent and in the manner reasonably requested
by the Company in the prosecution or defense of any claim involving a patent
covering any Invention or any litigation or other claim or proceeding involving
any Invention covered by this Agreement, but all expenses thereof shall be paid
by the Company.

          9.5. Injunctive Relief. The Executive acknowledges and agrees that the
Company will have no adequate remedy at law, and would be irreparably harmed, if
the Executive breaches or threatens to breach any of the provisions of this
Section 9 of this Agreement. The Executive agrees that the Company shall be
entitled to equitable and/or injunctive relief to prevent any breach or
threatened breach of this Section 9, and to specific performance of each of the
terms of such Section in addition to any other legal or equitable remedies that
the Company may have. The Executive further agrees that he shall not, in any
equity proceeding relating to the enforcement of the terms of this Section 9,
raise the defense that the Company has an adequate remedy at law.

          9.6. Special Severability. The terms and provisions of this Section 9
are intended to be separate and divisible provisions and if, for any reason, any
one or more of them is held to be invalid or unenforceable, neither the validity
nor the enforceability of any other provision of this Agreement shall thereby be
affected. It is the intention of the parties to this Agreement that the
potential restrictions on the Executive's future employment imposed by this
Section 9 be reasonable in both duration and geographic scope and in all other
respects. If for any reason any court of competent jurisdiction shall find any
provisions of this Section 9 unreasonable in duration or geographic scope or
otherwise, the Executive and the Company agree that the restrictions and
prohibitions contained herein shall be effective to the fullest extent allowed
under applicable law in such jurisdiction.

Executive. In no event shall the Executive be obligated to seek other employment
or take any other action by way of mitigation of the amounts payable to the
Executive under any of the provisions of this Agreement. The Company agrees to

                                 General Release

     IN CONSIDERATION OF the payment of $10.00, and for other good and valuable
consideration, the receipt of which is hereby acknowledged, and in consideration
of the terms and conditions contained in the Executive Employment Agreement,
dated as of July __, 2003, (the "Employment Agreement") by and between David J.
Waksmann, Esq. (the "Executive") and Constar International Inc. (the "Company"),
the Executive on behalf of himself and his heirs, executors, administrators, and
assigns, releases and discharges the Company and its past present and future
subsidiaries, divisions, affiliates and parents (including without limitation to
the foregoing Crown Cork & Seal Company, Inc.), and their respective current and
former officers, directors, employees, agents, and/or owners, and their
respective successors, and assigns and any other person or entity claimed to be
jointly or severally liable with the Company or any of the aforementioned
persons or entities (the "Released Parties") from any and all manner of actions
and causes of action, suits, debts, dues, accounts, bonds, covenants, contracts,
agreements, judgments, charges, claims, and demands whatsoever ("Losses") which
the Executive and his heirs, executors, administrators, and assigns have, had,
or may hereafter have, against the Released Parties or any of them arising out
of or by reason of any cause, matter, or thing whatsoever from the beginning of
the world to the date hereof, including without limitation, any and all matters
relating to the Executive's employment by the Company and the cessation thereof,
and any and all matters arising under any federal, state, or local statute,
rule, or regulation, or principle of contract law or common law, including but
not limited to, the Family and Medical Leave Act of 1993, as amended, 29 U.S.C.
(S)(S) 2601 et seq., Title VII of the Civil Rights Act of 1964, as amended, 42
U.S.C. (S)(S) 2000 et seq., the Age Discrimination in Employment Act of 1967, as
amended, 29 U.S.C. (S)(S) 621 et seq. (the "ADEA"), the Americans with
Disabilities Act of 1990, as amended, 42 U.S.C. (S)(S) 12101 et seq., the Worker

amended, 29 U.S.C. (S)(S) 1001 et seq., the Pennsylvania Human Relations Act, as
amended, 43 P.S. (S)(S) 955 et. seq., and any other equivalent or similar
federal, state, or local statute; provided, however, that the Executive does not
release or discharge the Released Parties from any of the Company's obligations
to him under the Employment Agreement or Losses arising under the ADEA which
arise after the date on which the Executive executes this general release. It is
understood that nothing in this general release is to be construed as an
admission on behalf of the Released Parties of any wrongdoing with respect to
the Executive, any such wrongdoing being expressly denied.

     The Executive represents and warrants that he fully understands the terms
of this general release, that he has been encouraged to seek, and has sought,
the benefit of advice of legal counsel, and that he knowingly and voluntarily,
of his own free will, without any duress, being fully informed, and after due
deliberation, accepts its terms and signs below as his own free act. Except as
otherwise provided herein, the Executive understands that as a result of
executing this general release, he will not have the right to assert that the
Company or any other of the Released Parties unlawfully terminated his
employment or violated any of his rights in connection with his employment or
otherwise.

                                       14

     The Executive further represents and warrants that he has not filed, and
will not initiate, or cause to be initiated on his behalf any complaint, charge,
claim, or proceeding against any of the Released Parties before any federal,
state, or local agency, court, or other body relating to any claims barred or
released in this General Release thereof, and will not voluntarily participate
in such a proceeding. However, nothing in this general release shall preclude or
prevent the Executive from filing a claim, which challenges the validity of this
general release solely with respect to the Executive's waiver of any Losses
arising under the ADEA. The Executive shall not accept any relief obtained on
his behalf by any government agency, private party, class, or otherwise with
respect to any claims covered by this General Release.

     The Executive may take twenty-one (21) days to consider whether to execute
this General Release. Upon the Executive's execution of this general release,
the Executive will have seven (7) days after such execution in which he may
revoke such execution. In the event of revocation, the Executive must present
written notice of such revocation to the Company's Chief Executive Officer. If
seven (7) days pass without receipt of such notice of revocation, this General
Release shall become binding and effective on the eighth (8th) day after the
execution hereof (the "Effective Date').

INTENDING TO BE LEGALLY BOUND, I hereby set my hand below:
