substantial restrictions on the transferability of both the GOF New Shares and

any of the Huntsman Parties, the Investors or the CP Parties, which breach shall
not have been cured within 30 days following receipt by the breaching party of
written notice of such breach from any of the other party hereto or prior to the
Closing, if sooner, or which breach, by its nature, cannot be cured prior to the
Closing, or (ii) if GOF's obligations under Sections 12.4(a) and 12.4(b) shall
have been terminated;

                (d)  by Family Holdings II (i) (provided that none of the

shall not otherwise affect the rights and obligations of any other party to this
Agreement, (i) (provided that none of the CP Parties is then in material breach
of any representation, warranty, covenant or other agreement contained herein)
if there shall have been a material breach of any of the material covenants or
agreements set forth in this Agreement on the part of any of the Huntsman
Parties, the Investors or GOF, which breach shall not have been cured within 30
days following receipt by the breaching party of written notice of such breach
from any of the other party hereto or prior to the Closing, if sooner, or which
breach, by its nature, cannot be cured prior to the Closing, (ii) if GOF's
obligations under Sections 12.4(a) and 12.4(b) shall have been terminated, (iii)
if

                                       43
<Page>

 CPF's obligations under Sections 12.5(a) and 12.5(c) shall have been
terminated, or (iv) if a Chapter 11 Case has not been filed on or before July

          11.2  EFFECT OF TERMINATION. In the event of termination of this
Agreement by any party to this Agreement as provided in Section 11.1, this
Agreement shall forthwith become void and have no effect except (a) Sections
11.2 and 13.1 shall survive any termination of this Agreement and (b) that
notwithstanding anything to the contrary contained in this Agreement, no party
shall be relieved or released from any liabilities or damages arising out of its
breach of any provision of this Agreement.

          11.3  AMENDMENT. Subject to compliance with applicable law, this
Agreement may be amended as provided herein. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of GOF, Family
Holdings II, CPF, HMP, H Corp and H Poly, and any such amendment shall be
binding on all parties hereto, and CPF agrees that its written approval of such
amendment(s) shall not be unreasonably withheld, conditioned or delayed.
Notwithstanding the foregoing, following the Closing, this Agreement may not be
amended except by an instrument in writing signed on behalf of each of GOF,
Family Holdings II, HMP, H Corp and H Poly, and any such amendment shall be
binding on all parties hereto; PROVIDED, HOWEVER, that any such amendment shall
also be subject to the prior reasonable acceptance of CPF where both (i) such
amendment would have a material adverse effect on the rights attributable to the
Interest of CPF (the "affected CPF rights") and (ii) such material adverse
effect would be disproportionate (after taking into account any
disproportionality in the relative rights of any CP Party and GOF prior to any
such amendment) to the effect such amendment would have on the rights
attributable to the Interest of GOF.

          11.4  EXTENSION; WAIVER. At any time prior to the Closing, the
parties to this Agreement may, to the extent legally allowed, (a) extend the

party hereto, (b) waive any inaccuracies in the representations and warranties
of any other party contained herein or in any document delivered pursuant hereto
and (c) waive compliance with any of the agreements or conditions of any other
party contained herein. Any agreement on the part of a party to this Agreement
to any such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party, but such extension or waiver or
failure to insist on strict compliance with an obligation, covenant, agreement
or condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.

          13.7  SEVERABILITY. Any term or provision of this Agreement which is

rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

contemplated by this Agreement without the consent of the other parties.

contemplated under Article II hereof with respect to the SPV, neither this
Agreement nor any of the rights, interests or obligations hereunder shall be
assigned by any of the parties hereto (whether by operation of law or otherwise)
