2.  DEMAND REGISTRATION

          (a) RIGHT TO DEMAND. At any time after the Hold Period Termination
Date, one or more Holders of the Notes shall have the right to make a written
request (such request, if in compliance with the requirements hereof, a "DEMAND
NOTICE") to the Issuer to register all or part of such Holders' Registrable
Notes under and in accordance with the provisions of the Securities Act, which
request must specify (i) the aggregate principal amount at maturity of the
Registrable Notes to be registered, and (ii) the intended method of disposition
thereof. Within 15 days after receipt of a Demand Notice, the Issuer will send
written notice of such Demand Notice to all Holders of Registrable Notes who did
not participate in the Demand Notice, and the Issuer will include in such
registration all Registrable Notes of such other Holders with respect to which
the Issuer has received written requests for inclusion therein within 10
Business Days after the receipt by the applicable Holder of the Issuer's written
notice. As soon as reasonably practicable thereafter, but in no event later than
the Demand Filing Deadline, the Issuer will cause to be filed a Registration
Statement covering such Registrable Notes that the Issuer has been so requested
to register providing for the registration under the Securities Act of such
Registrable Notes so to be registered in accordance with the intended method of
distribution specified in the Demand Notice (a "DEMAND REGISTRATION STATEMENT").
Such Registration Statement shall be on Form S-1 or any other appropriate form
permitting registration of such Registrable Notes. The Issuer shall not permit
any securities other than the Registrable Notes to be included in a Registration
Statement without the consent of the Holders of a majority of the principal
amount of the Notes to be registered in such Registration Statement. The Issuer
shall use its reasonable best efforts to cause any such Registration Statement
to be declared effective under the Securities Act as soon as practicable after
the date on which such Registration Statement is filed (such date, the "FILING
DATE"), but not later than the Effectiveness Date and to keep such Registration
Statement continuously effective for 90 days from the actual date of its
effectiveness (subject to extension pursuant to the last paragraph of Section 5)
(the "TERMINATION DATE"), or such shorter period ending when all Registrable
Notes covered by such Registration Statement have been sold in the manner set
forth and as contemplated in such Registration Statement. Notwithstanding
anything to the contrary in this Agreement, at any time, the Issuer may (i)
delay the filing of any Registration Statement or extend the Offering Memorandum

                                        4
<Page>

Deadline or (ii) delay or suspend (a) the effectiveness of a Registration
Statement or (b) the use of any Offering Memorandum, in either case of clause
(i) or clause (ii) for a reasonable period of time, but not in excess of an
aggregate of 90 days in any consecutive twelve month period, if the Board of
Managers of the Issuer determine in good faith that the filing of any such
Registration Statement (or effectiveness or the continuing effectiveness
thereof) or the circulation of an Offering Memorandum (or any other use thereof)
would require the disclosure of non-public material information that, in the
reasonable judgment of the Board of Managers of the Issuer, would be detrimental
to the Issuer if so disclosed or would otherwise materially adversely affect a
financing, acquisition, disposition, merger or other material transaction.

          (b) EFFECTIVENESS OF REGISTRATIONS. For purposes of Section 4(b), the
Issuer shall not be deemed to have effected a Registration under this Agreement
in connection with any Registration Statement or Offering Memorandum with
respect to which the Holders have withdrawn or cancelled their Demand Notice or
a Rule 144A Notice (i) at any time prior to the filing of a Registration
Statement or the completion of preparation of a preliminary Offering Memorandum,
as the case may be, in respect of such request or, (ii) in the case of an
Underwritten Offering, at any time following the failure of any condition to the
obligation of the underwriters to effect such offering (other than any such
failure which is caused by any action or failure to act on the part of any or
all of the Holders). No such withdrawal or cancellation shall affect the
Holders' obligation, if any, to pay the expenses described in Section 6. In
addition, if after a Registration Statement is initially declared effective by
the SEC, such Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Registration Statement shall be deemed not to have become
effective for purposes of this Agreement.

          (c) SUPPLEMENTS AND AMENDMENTS. The Issuer shall promptly supplement
and amend a Registration Statement if required by the rules, regulations or
instructions applicable to the registration form used for such Registration
Statement, if required by the Securities Act.

3.  ADDITIONAL INTEREST

          (a) The Issuer agrees that the Holders of Registrable Notes will
suffer damages if the Issuer fails to fulfill its obligations under Section 2 or
Section 8 hereof (except as a result of the failure of the Holders or any
underwriters to fulfill their obligations hereunder) and that it would not be
feasible to ascertain the extent of such damages with precision. Accordingly,
the Issuer agrees to pay, as liquidated damages, additional interest on
Registrable Notes ("ADDITIONAL INTEREST") under the circumstances and to the
extent set forth below (each of which shall be given independent effect):

          (i) if a Demand Registration Statement has not been filed on or prior
     to its Demand Filing Deadline, then commencing on the day after such Demand
     Filing Deadline, Additional Interest shall be accrued on the Registrable
     Notes to be covered by such Demand Registration Statement over and above
     the accrued interest at a rate of .25% per annum on the Accreted

                                        5
<Page>

     Value of such Registrable Notes for the first 90 days immediately following
     such Demand Filing Deadline, such Additional Interest rate increasing by an
     additional .25% per annum on the Accreted Value of such Registrable Notes
     at the beginning of each subsequent 90-day period;

          (ii) if such Demand Registration Statement has not been declared
     effective on or prior to such Effectiveness Date, then commencing on the
     day after such Effectiveness Date, Additional Interest shall be accrued on
     the Registrable Notes included in such Demand Registration Statement over
     and above the accrued interest at a rate of .25% per annum on the Accreted
     Value of such Notes for the first 90 days immediately following the day
     after such Effectiveness Date, such Additional Interest rate increasing by
     an additional .25% per annum on the Accreted Value of such Registrable
     Notes at the beginning of each subsequent 90-day period;

          (iii) if a Demand Registration Statement has been declared effective
     and such Demand Registration Statement ceases to be effective at any time
     prior to the Termination Date, then Additional Interest shall be accrued on
     the Registrable Notes affected thereby over and above any other accrued
     interest at a rate of .25% per annum on the Accreted Value of such Notes
     for the first 90 days commencing on the day such Registration Statement
     ceases to be effective, such Additional Interest rate increasing by an
     additional .25% per annum on the Accreted Value of such Demand Registrable
     Notes at the beginning of each such subsequent 90-day period;

          (iv) if a preliminary Offering Memorandum has not been prepared in
     accordance with the provisions of Section 8 on or prior to its Offering
     Memorandum Deadline, then commencing on the day after such Offering
     Memorandum Deadline, Additional Interest shall be accrued on the
     Registrable Notes to be covered by the Rule 144A Resale proposed in such
     Rule 144A Notice over and above the accrued interest at a rate of .25% per
     annum on the Accreted Value of such Registrable Notes for the first 90 days
     immediately following such Offering Memorandum Deadline, such Additional
     Interest rate increasing by an additional .25% per annum on the Accreted
     Value of such Registrable Notes at the beginning of each subsequent 90-day
     period;

PROVIDED, HOWEVER, that the Additional Interest rate on any Note may not exceed
at any one time in the aggregate 1.0% per annum on the Accreted Value of such
Registrable Notes; PROVIDED, FURTHER that Additional Interest shall not accrue
if the failure of the Issuer to comply with its obligations hereunder is a
result of the failure of the Holders or any underwriters to fulfill their
obligations hereunder; and PROVIDED, FURTHER, that (1) upon the filing of a
Registration Statement (in the case of (i) above), (2) upon the effectiveness of
a Registration Statement (in the case of (ii) above), (3) upon the effectiveness
of a substitute Registration Statement (in the case of (iii) above), or (4) upon
the preparation of a preliminary Offering Memorandum in accordance with the
provisions of Section 8 (except with respect to the requirement that such
Offering Memorandum be prepared on or before the Offering Memorandum

                                        6
<Page>

Deadline) (in the case of (iv) above), Additional Interest on such Registrable
Notes as a result of such clause shall cease to accrue.

          (b) The Issuer shall notify the Trustee within one Business Day after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid. Any amounts of Additional Interest due pursuant
to Section 3(a) will accrue semi-annually on each July 1, and January 1 (each an
"ADDITIONAL INTEREST PAYMENT DATE"), commencing with the first such date
occurring after any such Additional Interest commences to accrue. The amount of
Additional Interest will be determined on the basis of a 360-day year comprised
of twelve 30-day months.

          On any Additional Interest Payment Date, to the extent any Additional
Interest shall have accrued during the period from the previous Additional
Interest Payment Date (the "INTEREST PERIOD") due to the occurrence during such
Interest Period of an event described in Section 3(a), the Issuer shall issue a
note or notes to the holders on the Additional Interest Payment Date
substantially in the form of Exhibit A to the Indenture. The Accreted Value of
such notes shall be equal to the Additional Interest accrued during such
Interest Period and shall otherwise have the same terms as the Notes.

4.  REGISTRATIONS

          (a) UNDERWRITTEN REGISTRATIONS. If any of the Registrable Notes
covered by a Registration Statement or Offering Memorandum are to be sold in an
Underwritten Offering, the investment banker or investment bankers and manager
or managers that will manage the offering will be selected by the Holders of a
majority in aggregate principal amount at maturity of the Registrable Notes
included in such offering and reasonably acceptable to the Issuer.

          (b) NUMBER OF REGISTRATIONS. The Issuer shall be obligated to effect
up to five (5) Registrations (whether pursuant to Section 2(a) or Section 8) in
the aggregate pursuant to this Agreement.

5.  REGISTRATION PROCEDURES

          In connection with the obligations of the Issuer pursuant (i) to
Section 2 hereof, the Issuer shall use its reasonable best efforts to cause a
Registration Statement to become effective and remain effective as provided
herein, and (ii) to Section 8 hereof, the Issuer shall use its reasonable best
efforts to prepare a preliminary and a final Offering Memorandum, and in each
case (and to the extent applicable to the preparation of a preliminary and a
final Offering Memorandum pursuant to Section 8), without limiting generality of
the foregoing, the Issuer shall use its reasonable best efforts to, as
expeditiously as possible:

          (a) Before filing a Registration Statement or Prospectus or any
amendments or

                                        7
<Page>

supplements thereto (not including documents that would be incorporated or
deemed to be incorporated therein by reference), afford the Holders of the
Registrable Notes covered by a Registration Statement, their counsel and the
managing underwriters, if any, an opportunity to review, promptly, copies of all
such documents proposed to be filed, and such Holders shall have the opportunity
to object to any information pertaining to the Holders and their plan of
distribution that is contained therein and the Issuer will make the corrections
reasonably requested by such Holders prior to filing any such Registration
Statement, Prospectus or any amendment or supplement thereto; PROVIDED, HOWEVER,
that the Issuer shall not be required to afford such Holders an opportunity to
review a copy of (i) any such document that has not been materially changed from
a copy of such document that such person was previously afforded an opportunity
to review and (ii) any amendments or supplements to a Registration Statement or
Prospectus which are made solely as a result of any filing by the Issuer of
reports required to be filed pursuant to the Exchange Act.

          (b) Prepare and file with the SEC such amendments and post-effective
amendments to a Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the time periods prescribed
hereby; cause the related Prospectus to be supplemented by any Prospectus
supplement required by applicable law, and as so supplemented to be filed
pursuant to Rule 424 (or any similar provisions then in force) promulgated under
the Securities Act; and comply with the provisions of the Securities Act and the
Exchange Act and the rules and regulations of the SEC promulgated thereunder
applicable to it with respect to the disposition of all securities covered by
such Registration Statement as so amended or in such Prospectus as so
supplemented.

          (c) Notify the selling Holders of Registrable Notes, their counsel and
the managing underwriters, if any, promptly (but in any event within two
Business Days after becoming aware thereof) (i) when a Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective (including in such notice a written statement that any
Holder may, upon request, obtain, without charge, as many conformed copies of
such Registration Statement or post-effective amendment including financial
statements and schedules, including any documents incorporated or deemed to be
incorporated by reference and exhibits, as they may reasonably request), (ii) of
any request by the SEC for any amendment or supplement to such Registration
Statement or Prospectus included therein, (iii) of the issuance by the SEC of
any stop order suspending the effectiveness of such Registration Statement or of
any order preventing or suspending the use of any preliminary Prospectus or the
initiation of any proceedings for that purpose, (iv) if at any time when a
prospectus is required by the Securities Act to be delivered in connection with
sales of the Registrable Notes covered by such Registration Statement the
representations and warranties of the Issuer contained in any underwriting
agreement contemplated by Section 5(o) cease to be true and correct in all
material respects, (v) of the receipt by the Issuer of any notification with
respect to the suspension of the qualification or exemption from qualification
of such Registration Statement or any of the Registrable Notes for offer or sale
in any jurisdiction, or with respect to the initiation or threatening of any
proceeding for such purpose, (vi) of the happening of any event, the existence
of any condition or any information becoming known that

                                        8
<Page>

makes any statement made in such Registration Statement or related Prospectus,
or in an Offering Memorandum, or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires the making of any changes in such Registration Statement, Prospectus,
Offering Memorandum or documents so that, in the case of a Registration
Statement, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, not misleading, and that in the case of the Prospectus
or Offering Memorandum, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, and (vii) of the Issuer's reasonable
determination that a post-effective amendment to such Registration Statement or
a supplement to an Offering Memorandum would be appropriate.

          (d) Use its reasonable best efforts to prevent the issuance of any
order suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the qualification
(or exemption from qualification) of any of the Registrable Notes for sale in
any jurisdiction, and, if any such order is issued, to obtain the withdrawal of
any such order at the earliest possible moment.

          (e) If requested by the managing underwriters, if any, or the Holders
of a majority in aggregate principal amount at maturity of the Registrable Notes
being sold in connection with an Underwritten Offering, (i) promptly incorporate
in a Prospectus supplement or post-effective amendment or in an Offering
Memorandum, as applicable, such information as the managing underwriters, if
any, or such Holders reasonably request to be included therein, (ii) make all
required filings of any such Prospectus supplement or such post-effective
amendment as soon as practicable after the Issuer receives notification of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment, and (iii) supplement or make amendments to any Registration Statement
or Offering Memorandum, as applicable.

          (f) Furnish to each selling Holder of Registrable Notes who so
requests and to counsel and each managing underwriter, if any, without charge,
as many conformed copies of the Registration Statement and each post-effective
amendment thereto and of each Offering Memorandum and supplement thereto,
including financial statements and schedules, and, if requested, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits
as they may reasonably request.

          (g) Deliver to each selling Holder of Registrable Notes, their counsel
and the underwriters, if any, without charge, as many copies of each Prospectus
and Offering Memorandum (including each form of preliminary prospectus and
offering memorandum) and each amendment or supplement thereto and any documents
incorporated by reference therein as such Persons may reasonably request; and,
subject to the last paragraph of this Section 5, the Issuer hereby consents to
the use of such Prospectus and Offering Memorandum and each amendment or
supplement thereto by

                                        9
<Page>

each of the selling Holders of Registrable Notes and the underwriters or agents,
if any, in connection with the offering and sale of the Registrable Notes
covered by such Prospectus or Offering Memorandum and any amendment or
supplement thereto.

          (h) Prior to any public offering of Registrable Notes, to register or
qualify, and to cooperate with the selling Holders of Registrable Notes, the
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Notes for offer and sale under the securities
or Blue Sky laws of such jurisdictions within the United States as any selling
Holder, or the managing underwriters reasonably request in writing; PROVIDED
that where Registrable Notes are offered other than through an Underwritten
Offering, the Issuer agrees to cause its counsel to perform Blue Sky
investigations and file registrations and qualifications required to be filed
pursuant to this Section 5(h); keep such registration or qualification (or
exemption therefrom) effective during the period any Registration Statement is
required to be kept effective and do any and all other acts or things reasonably
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Notes covered by any Registration Statement; PROVIDED, HOWEVER, that
the Issuer shall not be required to (A) qualify generally to do business in any
jurisdiction where it is not then so qualified, (B) take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or (C) become subject to taxation in any such jurisdiction
where it is not then so subject.

          (i) Cooperate with the selling Holders of Registrable Notes and the
managing underwriters, if any, to facilitate the timely preparation and delivery
of certificates representing Registrable Notes to be sold, which certificates
shall not bear any restrictive legends and shall be in a form eligible for
deposit with The Depository Trust Company; and enable such Registrable Notes to
be in such denominations and registered in such names as the managing
underwriters, if any, or selling Holders of Registrable Notes may reasonably
request at least two Business Days prior to any sale of Registrable Notes.

          (j) Use its reasonable best efforts to cause the Registrable Notes
covered by a Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
selling Holders or the underwriters, if any, to consummate the disposition of
such Registrable Notes, except as may be required solely as a consequence of the
nature of such selling Holder's business, in which case the Issuer will

expense of the Issuer, a supplement or post-effective amendment to a
Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Notes being sold thereunder, such Prospectus will not contain an
untrue statement of a material fact or omit to state a

                                       10
<Page>

material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not

          (l) Use its reasonable best efforts to cause the Registrable Notes
covered by a Registration Statement or Offering Memorandum, as applicable, to be
rated with the appropriate rating agencies, if so requested by the Holders of a
majority in aggregate principal amount at maturity of Registrable Notes covered
by a Registration Statement or Offering Memorandum or the managing underwriters,
if any.

          (m) Prior to the actual effective date of a Registration Statement or

          (n) Cooperate with each selling Holder of Registrable Notes covered by
a Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Notes and their respective counsel in connection
with any filings required to be made with the National Association of Securities
Dealers, Inc. (the "NASD").

          (o) If requested by Holders of a majority in aggregate principal
amount at maturity of Registrable Notes covered by a Registration Statement or
Offering Memorandum, enter into an underwriting agreement in form, scope and
substance as is customary in underwritten offerings and take all such other
actions as are reasonably requested by the managing underwriters in order to
expedite or facilitate the registration or the disposition of such Registrable
Notes, and in such connection, (i) make such representations and warranties to
the underwriters, with respect to the business of the Issuer and its
subsidiaries, and a Registration Statement, Prospectus or Offering Memorandum
and documents, if any, incorporated or deemed to be incorporated by reference
therein, in each case, in form, substance and scope as are customarily made by
issuers to underwriters in underwritten offerings of debt securities similar to
the Registrable Notes, and confirm the same if and when requested; (ii) obtain

substance reasonably satisfactory to the managing underwriters, addressed to the

financial statements and financial data are, or are required to be, included in

indemnification provisions and procedures no less

                                       11
<Page>

favorable to the Participants than those set forth in Section 7 (or such other
less favorable provisions and procedures acceptable to Holders of a majority in
aggregate principal amount at maturity of Registrable Notes covered by such
Registration Statement or Offering Memorandum and the managing underwriters or
agents) with respect to all parties to be indemnified pursuant to said Section;
and (v) (A) with respect to an aggregate of two Registrations pursuant to
Section 2(a) or Section 8 upon the written request of the Holders providing the
Demand Notice or the Rule 144A Notice, as applicable, and as reasonably
determined by the Issuer, make the appropriate members of the Issuer's senior
management available to participate in customary "road show" activities with
respect to such two Registrations PROVIDED, HOWEVER, that the participation of
such management in such customary "road show" activities described in this
clause (A) shall count against the two management participations allotted hereby
regardless of whether the related Registration becomes "effective" within the
meaning of this Agreement or Exhibit A hereto, as the case may be, and (B) for
all other registrations pursuant to Section 2(a) or Section 8 (including Rule
144A Resales), as reasonably determined by the Issuer, make the appropriate
members of the Issuer's senior management available to participate in
conference-calls, meetings at the offices of the Issuer (or such other places as
agreed to by the Issuer in its sole discretion) and such other marketing support
activities for the Registrable Notes to be registered hereunder PROVIDED that in
each case under this clause (B) such activities shall be arranged so as to cause
minimal disruption to such management personnel's work-related duties to the
Issuer and its affiliates. The above clauses (i)-(iv) shall be done at each
closing under such underwriting agreement, or as and to the extent required
thereunder.

          (p) Make available for inspection by a representative of the selling
Holders of Registrable Notes, any underwriter participating in any such
disposition of Registrable Notes, if any, and any attorney or accountant or
other agent retained by any such representative of such selling Holders or
underwriter (collectively, the "INSPECTORS"), at the offices where normally
kept, during reasonable business hours, all financial and other records,
pertinent corporate documents and properties of the Issuer and its subsidiaries,
and cause the officers, directors and employees of the Issuer and its
subsidiaries to supply all information, in each case reasonably requested by any
such Inspector in connection with a Registration Statement or Offering
Memorandum; PROVIDED, HOWEVER, that any information that is designated in
writing by the Issuer, in good faith, as confidential at the time of delivery of
such information, shall be kept confidential by such Inspector unless (i)
disclosure of such information is required by court or administrative order,
(ii) disclosure of such information, in the opinion of counsel to such
Inspector, is necessary to avoid or correct a misstatement or omission of a
material fact in a Registration Statement, Prospectus or Offering Memorandum or
any supplement or post-effective amendment thereto or disclosure is otherwise
required by law, (iii) disclosure of such information is, in the opinion of
counsel for any Inspector, necessary or advisable in connection with any action,
claim, suit or proceeding, directly or indirectly, involving or potentially
involving such Inspector and arising out of, based upon, relating to, or
involving this Agreement, or any transactions contemplated hereby or arising
hereunder, or (iv) such information becomes generally available to the public
other than as a result of a disclosure or failure to safeguard by such
Inspector. Each selling Holder of such Registrable Notes will be required to
agree that information obtained by it as a result of

                                       12
<Page>

such inspections shall be deemed confidential and shall not be used by it as the
basis for any market transactions in the securities of the Issuer unless and
until such is made generally available to the public. Each selling Holder of
such Registrable Notes will be required to further agree that it will, upon
learning that disclosure of any such information is sought in a court of
competent jurisdiction, give notice to the Issuer and allow the Issuer to
undertake appropriate action to prevent disclosure of the information deemed
confidential at their expense.

          (q) Provide an indenture trustee for the Registrable Notes and, in
connection with any Registration Statement, cause the Indenture to be qualified
under the TIA not later than the effective date of the Registration Statement
relating to the Registrable Notes; and in connection therewith, cooperate with
the Trustee under any such indenture and the Holders of the Registrable Notes,
to effect such changes to such indenture as may be required for such Indenture
to be so qualified in accordance with the terms of the TIA; and execute, and use
its reasonable best efforts to cause such trustee to execute, all documents as
may be required to effect such changes, and all other forms and documents
required to be filed with the SEC to enable such indenture to be so qualified in
a timely manner.

          (r) Comply with all applicable rules and regulations of the SEC and
make generally available to its securityholders earnings statements satisfying
the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder
(or any similar rule promulgated under the Securities Act) no later than 45 days
after the end of any fiscal quarter (or 90 days after the end of any 12-month
period if such period is a fiscal year) commencing at the end of any fiscal
quarter in which Registrable Notes are sold to underwriters in a firm commitment
or best efforts Underwritten Offering.

          (s) Use its reasonable best efforts to take all other steps reasonably
necessary to effect the registration of the Registrable Notes covered by a
Registration Statement.

          The Issuer may require each selling Holder of Registrable Notes as to
which any registration is being effected to furnish to the Issuer such
information regarding such selling Holder and the distribution of such
Registrable Notes as the Issuer may, from time to time, reasonably request. The
Issuer may exclude from such registration the Registrable Notes of any selling
Holder so long as such selling Holder fails to furnish such information within a
reasonable time after receiving such request. If the identity of a selling
Holder of Registrable Notes is to be disclosed in a Registration Statement, such
selling Holder shall be permitted to include all information regarding such
selling Holder in such Registration Statement as it shall reasonably request.

          Each Holder, upon receipt of any notice from the Issuer of the
happening of any event of the kind described in Section 5(c), will forthwith
discontinue disposition of such Registrable Notes covered by such Registration
Statement or Prospectus (or Offering Memorandum), until such Holder's receipt of
the copies of the supplemented or amended Prospectus (or Offering Memorandum)
contemplated by Section 5(c), or until it is advised in writing (the "ADVICE")
by the Issuer that the use of the applicable Prospectus (or Offering Memorandum)
may be resumed. In the event the Issuer shall

                                       13
<Page>

give any such notice, the Termination Date shall be extended by the number of
days during such periods from and including the date of the giving of such
notice to and including the date when each seller of Registrable Notes covered
by such Registration Statement (or Offering Memorandum) shall have received the
copies of the supplemented or amended Prospectus (or Offering Memorandum)
contemplated by Section 5(c) or the Advice.

6.  EXPENSES

          All fees and expenses (including any underwriting discounts and
commissions) incident to the performance of or compliance with this Agreement by

7.  INDEMNIFICATION

          (a) The Issuer, agrees to indemnify and hold harmless each Holder of
Registrable Notes, the affiliates, officers, directors, representatives,
employees and agents of each such Person, and each Person, if any, who controls
any such Person within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (each, a "PARTICIPANT"), from and against any and
all losses, claims, damages, judgments, liabilities and reasonable expenses
(including, without limitation, the reasonable legal fees and other expenses
actually incurred in connection with any suit, action or proceeding or any claim
asserted) caused by, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in such Registration
Statement (or any amendment thereto) or Prospectus or Offering Memorandum (as
amended or supplemented if the Issuer shall have furnished any amendments or
supplements thereto) or any preliminary Prospectus or Offering Memorandum, or
caused by, arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the case of the Prospectus or Offering Memorandum in
the light of the circumstances under which they were made, not misleading;
PROVIDED, HOWEVER, that the Issuer will not be liable for any untrue statement
or omission or alleged untrue statement or omission in such Registration
Statement, Prospectus or Offering Memorandum that was (i) made by the Issuer in
reliance upon and in conformity with information furnished to the Issuer by the
selling Holders or the underwriters for use in such Registration Statement,
Prospectus or Offering Memorandum, or (ii) corrected by the Issuer in an amended
or supplemented Registration Statement, Prospectus or Offering Memorandum if the
Person asserting any such loss, claim, damage or liability purchased Registrable
Notes which are the subject thereof from such Participant in reliance upon such
inaccurate Prospectus or Offering Memorandum but was not sent or given a copy of
the corrected Prospectus or Offering Memorandum (as amended or supplemented) at
or prior to the written confirmation of the sale of such Registrable Notes, to
such Person, unless such failure to deliver such corrected Prospectus or
Offering Memorandum (as amended or supplemented) was a result of noncompliance
by the Issuer with Section 5 of this Agreement or (iii) contained in any
Prospectus or Offering Memorandum that the Participant delivered and was not
permitted to use in accordance with the last paragraph of Section 5.

          (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Issuer, the Issuer's affiliates, officers, directors,
representatives, employees and agents and each Person who controls the Issuer
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent (but on a several, and not joint, basis) as the
foregoing indemnity from the Issuer to each Participant, but only with reference
to information relating to such Participant furnished to the Issuer in writing
by such Participant expressly for use in such Registration Statement, Prospectus
or Offering Memorandum, any amendment or supplement thereto, or any preliminary
Prospectus or Offering Memorandum. The liability of any Participant under this
paragraph shall in no event exceed the proceeds received by such Participant
from sales of Registrable Notes giving rise to such obligations.

          (c) If any suit, action, proceeding (including any governmental or
regulatory

                                       15
<Page>

investigation), claim or demand shall be brought or asserted against any Person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such Person (the "INDEMNIFIED PERSON") shall promptly
notify the Person against whom such indemnity may be sought (the "INDEMNIFYING
PERSON") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the fees and expenses actually incurred by such counsel related to such
proceeding; PROVIDED, HOWEVER, that the failure to so notify the Indemnifying
Person (i) shall not relieve it of any obligation or liability which it may have
hereunder or otherwise (unless and only to the extent that such failure directly
results in the loss or compromise of any material rights or defenses by the
Indemnifying Person). In any such proceeding, any Indemnified Person shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Person unless (i) the Indemnifying
Person and the Indemnified Person shall have mutually agreed in writing to the
contrary, (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both the Indemnifying Person and the Indemnified Person and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
Indemnifying Person shall not, in connection with any proceeding or separate but
substantially similar related proceeding in the same jurisdiction arising out of
the same general allegations, be liable for the fees and expenses of more than
one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for the Participants and such control Persons
of Participants shall be designated in writing by Participants who sold a
majority in interest of Registrable Notes sold by all such Participants in the
related registration or offering and any such separate firm for the Issuer, its
directors, its officers and such control Persons of the Issuer shall be
designated in writing by the Issuer. The Indemnifying Person shall not be liable
for any settlement of any proceeding effected without its written consent, but
if settled with such consent or if there be a final non-appealable judgment for
the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. No Indemnifying Person shall, without the prior written consent of the
Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement includes an unconditional release of such Indemnified
Person from all liability on claims that are the subject matter of such
proceeding.

          (d) If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is

                                       16
<Page>

appropriate to reflect the relative fault of the Indemnifying Person or Persons
on the one hand and the Indemnified Person or Persons on the other in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities (or actions in respect thereof). The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Issuer
on the one hand or such Participants or such other Indemnified Person, as the
case may be, on the other, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission and
any other equitable considerations appropriate under the circumstances.

          (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by PRO RATA allocation
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages, judgments, liabilities and expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any reasonable legal or other expenses actually incurred by such
Indemnified Person in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Notes,
exceeds the amount of any damages that such Participant has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

          (f) The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability which the Indemnifying Persons
may otherwise have to the Indemnified Persons referred to above.

8.  RULE 144A TRANSACTION

          At any time after the Hold Period Termination Date but prior to the
time any Holder or Holders have given an aggregate of five Demand Notices or
Rule 144A Notices, including requests to execute a copy of the Exchange Offer
Registration Rights Agreement, any Holder shall be entitled to elect, by
providing written notice of such election (a "RULE 144A NOTICE") to the Issuer,
to pursue a sale of all or a portion of the Registrable Notes pursuant to Rule
144A under the Securities Act (a "RULE 144A RESALE"). Such written notice shall
specify the aggregate principal amount at maturity of the Registrable Notes to
be included in the Rule 144A Resale and the intended method of disposition
thereof. In connection with any Rule 144A Resale, the Holder or Holders may
elect (if an election for an exchange offer is available under applicable law
and regulations) to require the Issuer to enter into an Exchange Offer
Registration Rights Agreement (a "REGISTRATION ELECTION") with the initial
purchasers in

                                       17
<Page>

the Rule 144A Resale. If (and only if) such Registration Election is included in
a Rule 144A Notice, then such Rule 144A Notice and Registration Election
together shall count as only one (1) Registration within the meaning of Section
4(b). In the event that such Registration Election is made, then the Issuer
shall promptly execute an Exchange Offer Registration Rights Agreement.

          In connection with a Rule 144A Notice, the Issuer will cooperate in
connection with the related Rule 144A Resale by using its reasonable best
efforts (and subject to the cooperation of the Holders) to prepare a preliminary
Offering Memorandum on or before the Offering Memorandum Deadline and shall
otherwise comply with the provisions of Section 5 to the extent that such
provisions either refer to a Rule 144A Resale or to the extent that such
provisions are typically applicable to Rule 144A Resales. Without limiting the
foregoing and provided that the Holders shall have given at least one (1)
Business Day prior written notice to the Issuer as to the time of the pricing,
upon receipt of the pricing information from the Holders, the Issuer shall
promptly prepare a final Offering Memorandum that incorporates such pricing
information and makes any other changes that are necessary to prepare a final
Offering Memorandum. The failure of the Holders to give at least one (1)
Business Day prior written notice to the Issuer as to the time of the pricing
shall not affect the Issuer's obligation to prepare a final Offering Memorandum
unless and to the extent that such failure effects the ability of the Company to
promptly prepare such final Offering Memorandum.

9.  MISCELLANEOUS

          (a) NO INCONSISTENT AGREEMENTS. The Issuer has not, as of the date
hereof, and the Issuer shall not, after the date of this Agreement, enter into
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The Issuer has not entered and
will not enter into any agreement with respect to any of its securities which
will grant to any Person piggy-back rights with respect to a Registration
Statement.

          (b) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Issuer has obtained the
written consent of Holders of at least a majority of the then outstanding
aggregate principal amount at maturity of Registrable Notes. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders of Registrable
Notes whose securities are being sold pursuant to a Registration Statement and
that does not directly or indirectly affect, impair, limit or compromise the
rights of other Holders of Registrable Notes may be given by Holders of at least
a majority in aggregate principal amount at maturity of the Registrable Notes
being sold by such Holders pursuant to such Registration Statement; PROVIDED
that the provisions of this sentence may not be amended, modified or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

Ladies and Gentlemen:

Reference is made to the Registration Rights Agreement dated as of June 30, 1999
(the "Registration Rights Agreement") between Huntsman International Holdings
LLC, formerly known as Huntsman ICI Holdings LLC (the "Issuer") and ICI Finance
plc ("ICI Finance"), and to the letter agreement dated November 2, 2000, as
amended (the "B Note Letter Agreement"), between ICI Finance and the Issuer.
Capitalized terms used but not otherwise defined herein shall have the meanings
ascribed to them in the Registration Rights Agreement.

In consideration of the mutual covenants and agreements set forth herein, the
parties hereto agree as follows:

1.   The B Note Letter Agreement is hereby terminated, including, for the
     avoidance of doubt, (i) the obligations of the Issuer under the last
     sentence of the third paragraph of Section 7 thereof and (ii) any
     transaction notice served thereunder.

2.   The Hold Period Termination Date in the Registration Rights Agreement shall
     be deemed to have occurred 30 days after the date hereof so that, during
     such 30-day period, the Issuer shall have the ability to investigate and
     observe the market for its debt securities without any overhang from any
     pending sale or transfer of the Registrable Notes.

3.   The Registration Rights Agreement is hereby amended as follows:

     (a)  The following definition shall be added to Section 1:
<Page>

          dated as of o, 2001 between the Issuer and the Holders."

     (b)  in the seventh sentence in Section 2(a), the words "at any time, the
          Issuer may (i) delay the filing" shall be deleted and replaced by the
          words "the Issuer may, on one occasion only in any consecutive twelve
          month period (i) delay the filing";

     (c)  in the seventh sentence in Section 2(a), the words "90 days in any
          consecutive twelve month period" shall be deleted and replaced by the

     (d)  in the first sentence of Section 2(b), clause (ii), after the words
          "(other than any such failure which is caused by any action or failure
          to act on the part of any or all of the Holders)", the following words
          shall be inserted: "which is set forth in any written purchase
          agreement entered into, inter alia, between the Holders, on the one
          hand, and such underwriter, on the other hand (it being understood and
          agreed that the failure or inability of the Holders or any underwriter
          to enter into a purchase agreement shall not constitute a failure of
          any condition for the purposes of this clause (ii))".

     (e)  Section 4(b) shall be deleted in its entirety and replaced by the
          following:

          "NUMBER OF REGISTRATIONS. The Issuer shall be obligated to effect up
          to six (6) Registrations (whether pursuant to Section 2(a) or Section

          five (5) of such Demand Notices or Rule 144A Notices may be given at
          any time and one additional Demand Notice or Rule 144A Notice may only
          be given at any time on or after January 1, 2004, and PROVIDED FURTHER
          that each Private Sale Notice given by a Holder pursuant to the
          Private Sale Letter Agreement shall be counted as a Registration
          effected under this Agreement.";

          Registrations pursuant to Section 2(a) or Section 8" shall be deleted

          Registrations for which a Demand Notice or Rule 144A Notice is given
          prior to January 1, 2004) pursuant to Section 2(a) or Section 8,";

     (g)  in the first sentence of Section 5(o), clause (v)(A), the words "with

          participations allotted hereby regardless of whether any such Private
          Sale is consummated,";

     (j)  in the proviso to Section 5(o), clause (v)(B), after the words "the
          Issuer and its affiliates." the following words shall be inserted:
          "Notwithstanding the foregoing, the Issuer will not be obligated to
          participate, or to make members of the Issuer's management available
          to participate, in more than four roadshows under this Agreement.";

          or compliance with this Agreement or the Private Sale Letter Agreement
          by the Issuer shall be borne by the Holders, and shall constitute a

4.   At any time and from time to time after the date hereof until ICI Finance
     and/or its affiliates has completed (x) the sale of all of its Registrable
     Notes or (y) the sale or other disposition of a majority of the voting or
     economic interest in any subsidiary or subsidiaries that, directly or
     indirectly, hold all of the Registrable Notes, the Issuer shall reasonably
     cooperate and assist ICI Finance in any effort to pre-market the
     Registrable Notes, by making reasonably available the relevant senior
     management of the Issuer to participate in a reasonable number of due
     diligence conference calls with ICI Finance and/or its affiliates and any
     prospective purchaser (subject to execution of Confidentiality Agreements),
     and the provision of historical financial information to any prospective
     purchaser, PROVIDED that such activities shall be arranged so as to cause
     minimal disruption to such management personnel's work-related duties to
     the Issuer and its affiliates.

5.   At any time after the date hereof until ICI Finance and/or its affiliates
     has completed (x) the sale of all of its Registrable Notes or (y) the sale
     or other disposition of a majority of the voting or economic interest in
     any subsidiary or subsidiaries that, directly or indirectly, hold all of
     the Registrable Notes, ICI Finance and/or its affiliates shall be entitled
     to elect, by providing written notice of such election (a "Private Sale
     Notice") to the Issuer, to pursue a private sale of all or part of the
     Registrable Notes of ICI Finance and/or its affiliates (a "Private Sale"),
     PROVIDED that ICI Finance and/or its affiliates will not be deemed to have
     given (for the purposes of Section 4(b) of the Registration Rights
     Agreement and for purposes of the following paragraph), a Private Sale
     Notice with respect to which the Holders have withdrawn or cancelled such
     Private Sale Notice (i) at any time prior to the completion or preparation
     of an Information Memorandum described in Section 5(d) below (for the
     avoidance of doubt, the test under this clause (i) is completion of the
     Information Memorandum, not delivery thereof to any prospective purchaser)
     or (ii) at any time following the failure of any condition to the
     obligations of any purchaser to effect such Private Sale (other than any
     such failure which is caused by any action or failure to act on the part of
     any or all of the Holders) which are set forth in any written purchase
     agreement entered into, inter alia, between ICI Finance and/or any of its
     affiliates, on the one hand, and such prospective purchaser, on the other
     hand (it being understood and agreed that the failure or inability of ICI
     Finance, any of its affiliates or any prospective purchaser to enter into a
     purchase agreement shall not constitute a failure of any condition for the
     purposes of this clause (ii)).

     ICI Finance and/or its affiliates shall be entitled to give up to eight
     Private Sale Notices and the Issuer shall be obligated to participate in up
     to six Private Sale Roadshows (as defined below) in the aggregate pursuant
     to this letter agreement, PROVIDED that:

                                       5
<Page>

     (1)  no more than three Private Sale Notices may be given within any two
          year period and no more than two Private Sale Notices may be given in
          any one year period,

     (2)  each Registration effected pursuant to the Registration Rights
          Agreement shall reduce by one the number of Private Sale Notices that
          ICI Finance and/or its affiliates can give hereunder, and

     (3)  each roadshow which occurs pursuant to the Registration Rights
          Agreement shall be counted as a Private Sale Roadshow hereunder.

     For the avoidance of doubt, ICI Finance and/or its affiliates may:

     (x)  subject to the limitations and conditions set forth herein, give two
          Private Sale Notices even if all six Registrations under the
          Registration Rights Agreement (either by giving a Demand Notice, Rule
          144A Notice or Private Sale Notice) have been effected, and

     (y)  subject to the limitations and conditions set forth herein, instruct
          the Issuer to participate in two Private Sale Roadshows even if all
          four roadshows under the Registration Rights Agreement have occurred.

     In connection with a Private Sale, the Issuer will comply with the
     provisions of Section 5 of the Registration Rights Agreement to the extent
     that such provisions would be customary for a private sale transaction
     (including, without limitation, the requirements of paragraphs (a)-(j)
     below), and will also reasonably cooperate with and assist ICI Finance
     and/or its affiliates in any such Private Sale by using its reasonable best
     efforts, as expeditiously as practicable, to:

     (a)  enter into a purchase agreement relating to a purchase of the
          Registrable Notes, which agreement will contain terms and conditions
          customary in transactions of a similar kind, and in which the Issuer
          will give such representations, warranties and indemnities and obtain
          such opinions of the Issuer's counsel and accountants' comfort letters
          as are customary in private sale transactions;

     (b)  in the event that ICI Finance and/or its affiliates shall sell all of
          the Registrable Notes to one or more purchasers in a single
          transaction, the Issuer shall enter into a registration rights
          agreement with such purchasers relating to the Registrable Notes
          substantially in the form attached hereto as Exhibit A (the
          "Purchasers' Registration Rights Agreement") and upon execution and
          delivery of the Purchasers Registration Rights Agreement, the Issuer's
          obligations under the Registration Rights Agreement and

                                       6
<Page>

          under this letter agreement shall automatically terminate and the
          Issuer shall have no further liability or obligation thereunder or
          hereunder;

     (c)  prior to the first sale by ICI Finance or any of its affiliates of any
          Registrable Notes, negotiate in good faith with regard to any
          reasonable changes proposed by the prospective purchasers to the
          Amended and Restated Indenture dated as of the date hereof governing
          the Notes (the "Indenture") and the Purchasers' Registration Rights
          Agreement, PROVIDED that the Issuer will not be obligated to agree to
          any such changes that (i) would be detrimental to the Issuer's or ICI
          Finance and/or its affiliates' interest, respectively (except in any
          immaterial respect) and (ii) would constitute a "significant
          modification" as determined under U.S. Treasury
          Regulations SECTION 1.1001-3), in each case, in the reasonable
          judgment of the Issuer;

     (d)  prepare an information memorandum and any necessary or appropriate
          amendment or supplement thereto (the "Information Memorandum")
          regarding the business, operations and prospects of the Issuer,
          including a review of the Issuer's historical and projected financial
          information by business unit. The Information Memorandum will, once
          approved by the Issuer, be provided by ICI Finance and/or its
          affiliates to prospective purchasers on a strictly confidential basis,
          PROVIDED that the Information Memorandum will not be provided to a
          Holder (whether or not a Member of the Issuer as defined in the
          Issuer's LLC Agreement), any prospective purchaser or any other person
          who has not entered into a written confidentiality agreement with
          respect thereto and to any other confidential information provided by
          the Issuer or its advisors, including any such information provided or
          obtained pursuant to this letter agreement, that is customary for a
          private sale transaction and reasonably satisfactory, in form and
          substance, to the Issuer (each, a "Confidentiality Agreement"). The
          Issuer will be responsible for the contents of the Information
          Memorandum, subject to normal exceptions, including any forward
          looking information contained therein, which will be prepared in good
          faith;

     (e)  subject to execution of Confidentiality Agreements, provide for review
          any information provided to any of the Issuer's lenders, or to the
          lenders of any of the Issuer's principal operating subsidiaries,
          within the past 12 months;

     (f)  subject to execution of Confidentiality Agreements, provide all
          information and documentation reasonably requested by a prospective
          purchaser and its counsel in connection with their

                                       7
<Page>

          investigation of the Issuer's business, financial performance and
          prospects, including, without limitation, everything to be provided to
          Inspectors pursuant to Section 5(p) of the Registration Rights
          Agreement;

     (g)  subject to execution of Confidentiality Agreements,

          (i)  as reasonably determined by the Issuer, make the appropriate
               senior management of the Issuer (including, without limitation,
               the Issuer's CFO and Treasurer) and each of the Issuer's
               principal business units available to participate in conference
               calls, meetings at the offices of the Issuer (or such other
               places as agreed between the parties and such other marketing
               support activities for the Registrable Notes to be sold under
               this letter agreement, PROVIDED that in each case under this
