held in the Pledge Account.

       SECTION 5. DISBURSEMENTS FROM THE PLEDGE ACCOUNT; TRANSFERS OF ADDITIONAL
AMOUNTS TO THE PLEDGE ACCOUNT.

              (a) On July 26, 2002, the Indenture Trustee, may, pursuant to
written instructions given by the Indenture Trustee to the Pledge Trustee (each
an "Issuer Order"), instruct the Pledge Trustee to release from the Pledge
Account, and pay to the Holders of the Securities electing to require the

sufficient to provide for payment in full of the Purchase Price of the
Securities. Upon receipt of an Issuer Order, the Pledge Trustee will release
funds from (and to the extent of) proceeds of the Pledged Securities in the
Pledge Account in an amount sufficient to provide for the payment in full of
such Purchase Price, as instructed in such Issuer Order, and to transfer such

in respect of the Pledged Securities then credited to the Pledge Account,
together with any cash then held in the Pledge Account, exceed 100% of the
amount necessary, as certified in writing by a nationally recognized firm of
independent accountants selected by the Grantor and delivered to the Indenture
Trustee, to provide for the payment of the Purchase Price of all of the
outstanding Securities on July 26, 2002, the Grantor may instruct the Indenture
Trustee, pursuant to an Issuer Order, to direct the Pledge Trustee to release
any such excess amount to the Grantor or to another party designated by the
Grantor (the "Grantor's Designee"). Upon receipt of such Issuer Order (which
shall be accompanied by a certificate from such nationally recognized firm of
independent accountants stating that the scheduled interest and principal
payments in respect of the Pledged Securities credited to the Pledge Account,
together with any cash held in the Pledge Account, in each case after giving
effect to such release, equal or exceed 100% of the amount necessary to provide
for the payment of the Purchase Price of all of the outstanding Securities on
July 26, 2002), the Indenture Trustee shall, as soon as reasonably practicable,
instruct the Pledge Trustee to release funds from (and to the extent of)
proceeds of such Pledged Securities in accordance with such Issuer Order and the
accompanying certificate and to transfer such funds to the Grantor or the
Grantor's Designee, as the case may be.

              (c) Upon the release of any Collateral from the Pledge Account in
accordance with the terms of this Section 5, whether upon release of proceeds of
Collateral to the Indenture Trustee for the benefit of the Holders as payment of
the Purchase Price of the Securities or upon release of proceeds of Collateral
to the Grantor or the Grantor's Designee as provided in Section 5(b), the
security interest evidenced by this Agreement in such released Collateral will
automatically terminate and be of no further force and effect.

              (d) On the Business Day prior to July 26, 2002, the Indenture
Trustee shall give the Pledge Trustee notice (by Issuer Order) as to the amount
which will be paid pursuant to Section 5(a).

              (e) Nothing contained in this Agreement (including without
limitation the provisions hereof regarding the delivery of Issuer Orders by the
Indenture Trustee to the Pledge Trustee) shall (i) afford the Grantor any right
to issue entitlement orders to the Pledge Trustee or any other Person with
respect to the Pledge Account or any security entitlement in respect of the
Pledged Securities, or otherwise afford the Grantor control of the Pledge
Account or any such security entitlement, or (ii) otherwise give rise to any
rights of the Grantor with respect to the Pledge Account, the Pledged
Securities, or any security entitlement thereto, other than the Grantor's rights
under this Agreement as the beneficial owner of Collateral pledged to and
subject to the exclusive dominion and control of the Indenture Trustee in its
capacity as such. The Grantor acknowledges, confirms and agrees that the
Indenture Trustee holds a security interest in the Pledged Securities solely as
Indenture Trustee for the Holders of the Securities.

prior to any release of any Collateral to the Grantor or the Grantor's Designee,
the Grantor shall deliver to the Indenture Trustee such certificates, opinions
or other documents as may be required by the Indenture or the Trust Indenture
Act in connection with such release and shall otherwise comply with the
requirements of the Indenture and the Trust Indenture Act applicable thereto.

              (g) If at any time the Grantor is obligated to pay any amount to
the Indenture Trustee pursuant to the terms of this Agreement and the Indenture
Trustee charges such amount against the Pledge Account with the result that the
scheduled interest and principal payments in respect of the Pledged Securities
then credited to the Pledge Account, together with any cash then held in the
Pledge Account, are less than 100% of the amount necessary to provide for the
payment in full of amounts owing on the Securities, the Grantor shall deposit
cash into the Pledge Account in the amount of such deficiency and shall deliver
to the Indenture Trustee a certificate from a nationally recognized firm of
independent accountants stating that the scheduled interest and principal
payments in respect of the Pledged Securities credited to the Pledge Account,
together with any cash held in the Pledge Account, in each case after giving
effect to such deposit by the Grantor, equal or exceed 100% of the amount
necessary to provide for the payment in full amounts owing on the Securities.

Securities and the crediting thereof to the Pledge Account in accordance with

Trustee) or to effect the purposes of this Agreement.

              (b) The Grantor hereby authorizes the Indenture Trustee to file
any financing or continuation statements with respect to the Collateral without

detail, and (y) contain any other information required by part 5 of Article 9 of
the Uniform Commercial Code of the appropriate jurisdiction for the sufficiency
or filing office acceptance of any financing statement or amendment.

              (f) The Pledge Trustee covenants and agrees with the Grantor and
the Indenture Trustee that for so long as the Pledge Trustee holds assets in the
Pledge Account, the Pledge Trustee will, as soon as reasonably practicable,

other time as the parties may mutually agree. The Grantor will provide the
Pledge Trustee with a schedule of its fiscal months as soon as such schedule

INDENTURE TRUSTEE'S REASONABLE DISCRETION TO TAKE ANY ACTION AND TO EXECUTE ANY
INSTRUMENT THAT THE INDENTURE TRUSTEE MAY DEEM NECESSARY OR ADVISABLE TO
ACCOMPLISH THE PURPOSES OF THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION:

              (a) to ask for, demand, collect, sue for, recover, compromise,
receive and give acquittance and receipt for moneys due and to become due under
or in respect of any of the Collateral,

              (b) to receive, indorse and collect any drafts or other
instruments, documents and chattel paper,

              (c) to file any claims or take any action or institute any
proceedings that the Indenture Trustee may reasonably deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
the rights of the Indenture Trustee with respect to any of the Collateral, and

              (d) to pay or discharge any taxes or Liens levied or placed upon
the Collateral, the legality or validity thereof and the amounts necessary to
discharge the same to be determined by the Indenture Trustee in its sole
discretion, and such payments made by the Indenture Trustee to become part of
the Secured Obligations of the Grantor to the Indenture Trustee, due and payable
immediately upon demand;

provided, however, that the Indenture Trustee shall have no obligation to
perform any of the foregoing actions. The Indenture Trustee's authority under
this Section 10 shall include, without limitation, the authority to endorse and
negotiate any checks or instruments representing proceeds of Collateral in the
name of the Grantor, execute and give receipt for any certificate of ownership
or any document constituting Collateral, transfer title to any item of
Collateral, sign the Grantor's name on all financing statements (to the extent
permitted by applicable law) or any other documents reasonably deemed necessary
or appropriate by the Indenture Trustee to preserve, protect or perfect the
security interest in the Collateral and to file the same, prepare, file and sign
the Grantor's name on any notice of Lien, and to take any other actions arising
from or incident to the powers granted to the Indenture Trustee in this
Agreement. This power of attorney is coupled with an interest and is irrevocable
by the Grantor.

       SECTION 11. NO ASSUMPTION OF DUTIES; REASONABLE CARE. THE RIGHTS AND
POWERS CONFERRED ON THE PLEDGE TRUSTEE AND THE INDENTURE TRUSTEE HEREUNDER ARE
SOLELY TO PRESERVE AND PROTECT THE SECURITY INTEREST OF THE INDENTURE TRUSTEE
AND THE HOLDERS OF THE SECURITIES IN AND TO THE COLLATERAL GRANTED HEREBY AND
SHALL NOT BE INTERPRETED TO, AND SHALL NOT, IMPOSE ANY DUTIES ON THE PLEDGE
TRUSTEE OR THE INDENTURE TRUSTEE IN CONNECTION THEREWITH OTHER THAN THOSE
EXPRESSLY PROVIDED HEREIN OR IN THE INDENTURE OR IMPOSED UNDER APPLICABLE LAW.
EXCEPT AS PROVIDED BY HEREIN, BY APPLICABLE LAW OR BY THE INDENTURE, EACH OF THE
PLEDGE TRUSTEE AND THE INDENTURE TRUSTEE SHALL BE DEEMED TO HAVE EXERCISED
REASONABLE CARE IN THE CUSTODY AND PRESERVATION OF ANY COLLATERAL IN ITS
POSSESSION IF THE COLLATERAL IS ACCORDED TREATMENT SUBSTANTIALLY EQUAL TO THAT
WHICH THE PLEDGE TRUSTEE OR INDENTURE TRUSTEE, AS THE CASE MAY BE, ACCORDS
SIMILAR PROPERTY HELD BY ITSELF FOR ITS OWN ACCOUNT, IT BEING UNDERSTOOD THAT
NEITHER THE INDENTURE TRUSTEE NOR THE PLEDGE TRUSTEE SHALL HAVE ANY
RESPONSIBILITY FOR (a) ASCERTAINING OR TAKING ACTION WITH RESPECT TO CALLS,
CONVERSIONS, EXCHANGES,

                                       8
<PAGE>   9

MATURITIES OR OTHER MATTERS RELATIVE TO ANY COLLATERAL, WHETHER OR NOT THE
PLEDGE TRUSTEE OR THE INDENTURE TRUSTEE HAS OR IS DEEMED TO HAVE KNOWLEDGE OF
SUCH MATTERS, (b) TAKING ANY NECESSARY STEPS TO PRESERVE RIGHTS AGAINST ANY
PARTIES WITH RESPECT TO ANY COLLATERAL OR (c) INVESTING OR REINVESTING ANY OF
THE COLLATERAL OR ANY LOSS ON ANY INVESTMENT. WITHOUT LIMITING ANY RIGHTS OF THE
INDENTURE TRUSTEE HEREUNDER, THE RIGHTS AND LIMITATIONS UPON THE LIABILITY OF
THE INDENTURE TRUSTEE SET FORTH IN ARTICLE 7 OF THE INDENTURE ARE EXPRESSLY
INCORPORATED HEREIN AND MADE A PART HEREOF.

       SECTION 12. INDEMNITY. THE GRANTOR SHALL INDEMNIFY, HOLD HARMLESS AND
DEFEND THE INDENTURE TRUSTEE, THE PLEDGE TRUSTEE AND EACH OF THEIR RESPECTIVE
DIRECTORS, OFFICERS, AGENTS AND EMPLOYEES, FROM AND AGAINST ANY AND ALL CLAIMS,
ACTIONS, OBLIGATIONS, LIABILITIES AND EXPENSES, INCLUDING DEFENSE COSTS,
INVESTIGATIVE FEES AND COSTS, AND LEGAL FEES AND DAMAGES ARISING FROM THEIR
EXECUTION OF OR PERFORMANCE UNDER THIS AGREEMENT, EXCEPT TO THE EXTENT THAT SUCH
CLAIM, ACTION, OBLIGATION, LIABILITY OR EXPENSE IS DIRECTLY ATTRIBUTABLE TO THE
BAD FAITH, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PERSON.
THIS INDEMNIFICATION SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT FOR A
PERIOD OF TIME FROM THE TERMINATION OF THIS AGREEMENT EQUAL TO THE STATUTORY
LIMITATION OF CLAIMS FOR BREACH OF A WRITTEN CONTRACT UNDER THE LAWS OF THE
STATE OF NEW YORK AS IN EFFECT ON THE DATE HEREOF.

       SECTION 13. REMEDIES UPON EVENT OF DEFAULT. IF ANY EVENT OF DEFAULT SHALL
HAVE OCCURRED AND BE CONTINUING:

              (a) The Indenture Trustee may exercise, in addition to all other
rights given by law or by this Agreement or the Indenture, all of the rights and
remedies with respect to the Collateral of a secured party under the Uniform
Commercial Code as in effect from time to time in any relevant jurisdiction and
also may, without notice except as specified below, (i) sell, redeem or
liquidate any of the Collateral, (ii) transfer any or all of the Collateral to
any account designated by the Indenture Trustee, including an account or
accounts established in the Indenture Trustee's name, (iii) register title to
any Collateral in any name specified by the Indenture Trustee, including the
name of the Indenture Trustee or any of its nominees or agents, without
reference to any interest of the Grantor, or (iv), sell the Collateral or any
part thereof in one or more parcels at any broker's board or at public or
private sale, in one or more sales or lots, at any of the Indenture Trustee's
offices or elsewhere, for cash, on credit or for future delivery, and upon such
other terms as the Indenture Trustee may deem commercially reasonable. The
Grantor agrees that the Collateral is of a type customarily sold on recognized
markets and, accordingly, that no notice to any Person is required before any
sale of any of the Collateral pursuant to the terms of this Agreement; provided,
however that, without prejudice to the foregoing, to the extent notice of any
such sale shall be required by law, the Grantor agrees that at least ten days'
notice to the Grantor of the time and place of any public sale or the time after
which any private sale is to be made shall constitute reasonable notification.
The Indenture Trustee shall not be obligated to make any sale of Collateral
regardless of notice of sale having been given. The Indenture Trustee may
adjourn any public or private sale from time to time by announcement at the time
and place fixed therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned. The purchaser of any or all
Collateral so sold shall thereafter hold the same absolutely free from any
claim, encumbrance or right of any kind whatsoever created by or through the
Grantor. Any sale of the Collateral conducted in conformity with reasonable
commercial practices of banks, insurance companies, commercial finance
companies, or other financial institutions disposing of property similar to the
Collateral shall be deemed to be commercially reasonable. The Indenture Trustee
or any Holder of Securities may, in its own name or in the name of a designee or
nominee, buy any of the Collateral at any public sale and, if permitted by
applicable law, at any private sale. All expenses (including court costs and
reasonable attorneys' fees, expenses and disbursements) of, or incident to, the
enforcement of any of the provisions hereof shall be recoverable from the
proceeds of the sale or other disposition of the Collateral. If there are
insufficient Pledged Securities together with proceeds of Pledged Securities and
other Collateral in the Pledge Account to make any required payment on the
Secured Obligations, the Grantor shall be liable to the Indenture Trustee for
any deficiency.

              (b) The Indenture Trustee may, without notice to the Grantor
except as required by law and at any time or from time to time, charge, set-off
and otherwise apply all or any part of the Secured Obligations against the
Pledge Account or any part thereof.

                                       9
<PAGE>   10

              (c) The Grantor further agrees to use its best efforts to do or
cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Collateral pursuant to this Section 13 valid
and binding and in compliance with any and all other applicable requirements of
law. The Grantor further agrees that a breach of any of the covenants contained
in this Section 13 will cause irreparable injury to the Indenture Trustee and
the Holders of the Securities, that the Indenture Trustee and the Holders of the
Securities have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section 13 shall be
specifically enforceable against the Grantor and, to the fullest extent
permitted by law, the Grantor hereby waives and agrees not to assert any
defenses against an action for specific performance of such covenants except for
a defense that no Event of Default has occurred and is continuing.

       SECTION 14. EXPENSES. THE GRANTOR SHALL PAY THE PLEDGE TRUSTEE
COMPENSATION FOR ITS SERVICES HEREUNDER IN ACCORDANCE WITH THE TERMS SET FORTH
IN A SEPARATE AGREEMENT BETWEEN THE GRANTOR AND THE PLEDGE TRUSTEE. THE GRANTOR
WILL UPON DEMAND PAY TO THE INDENTURE TRUSTEE AND THE PLEDGE TRUSTEE THE AMOUNT
OF ANY AND ALL REASONABLE EXPENSES, INCLUDING, WITHOUT LIMITATION, THE
REASONABLE FEES, EXPENSES AND DISBURSEMENTS OF COUNSEL, EXPERTS AND AGENTS
RETAINED BY THE INDENTURE TRUSTEE OR THE PLEDGE TRUSTEE, AS THE CASE MAY BE,
THAT THE INDENTURE TRUSTEE OR THE PLEDGE TRUSTEE, AS THE CASE MAY BE, MAY INCUR
IN CONNECTION WITH (a) THE REVIEW, NEGOTIATION AND ADMINISTRATION OF THIS
AGREEMENT, (b) THE CUSTODY OR PRESERVATION OF, OR THE SALE OF, COLLECTION FROM,
OR OTHER REALIZATION UPON, ANY OF THE COLLATERAL, (c) THE EXERCISE OR
ENFORCEMENT OF ANY OF THE RIGHTS OF THE INDENTURE TRUSTEE AND THE HOLDERS OF THE
SECURITIES HEREUNDER OR (d) THE FAILURE BY THE GRANTOR TO PERFORM OR OBSERVE ANY
OF THE PROVISIONS HEREOF.

              Section 15.2. No Adverse Interpretation of Other Agreements. This
Agreement may not be used to interpret another pledge, security or debt
agreement of the Grantor or any subsidiary thereof. No such pledge, security or
debt agreement (other than the Indenture) may be used to interpret this
Agreement.

              Section 15.3. Severability. The provisions of this Agreement are
severable, and if any clause or provision shall be held invalid, illegal or
unenforceable in whole or in part in any jurisdiction, then, to the fullest
extent permitted by law, such invalidity or unenforceability shall affect in
that jurisdiction only such clause or provision, or part thereof, and shall not
in any manner affect such clause or provision in any other jurisdiction or any
other clause or provision of this Agreement in any jurisdiction.

              Section 15.4. Headings. The headings in this Agreement have been
inserted for convenience of reference only, are not to be considered a part
hereof and shall in no way modify or restrict any of the terms or provisions
hereof.

              Section 15.5. Counterpart Originals. This Agreement may be signed
in two or more counterparts, each of which shall be deemed an original, but all
of which shall together constitute one and the same agreement.

              Section 15.6. Benefits of Agreement. Nothing in this Agreement,
express or implied, shall give to any Person, other than the parties hereto and
their successors hereunder, and the Holders of the Securities, any benefit or
any legal or equitable right, remedy or claim under this Agreement.

              Section 15.7. Amendments, Waivers and Consents. Any amendment or
waiver of any provision of this Agreement and any consent to any departure by
the Grantor from any provision of this Agreement shall be effective only if made
or duly given in compliance with all of the terms and provisions of the
Indenture, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given. Neither the
Indenture Trustee nor any Holder of Securities shall be deemed, by any act,
delay, indulgence, omission or otherwise, to have waived any right or remedy
hereunder or to have acquiesced in any Event of Default or in any breach of any
of the terms and conditions hereof. Failure of the Indenture Trustee or any
Holder of Securities to exercise, or delay in exercising, any right, power or
privilege hereunder shall not preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. A waiver by the Indenture
Trustee or any Holder of Securities of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy that the
Indenture Trustee or such Holder would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

              Section 15.8. Interpretation of Agreement. To the fullest extent
permitted by applicable law, acceptance of or acquiescence in a course of
performance rendered under this Agreement shall not be relevant to determine the
meaning of this Agreement even though the accepting or acquiescing party had
knowledge of the nature of the performance and opportunity for objection.

              Section 15.9. Continuing Security Interest; Termination.

              (a) This Agreement shall create a continuing security interest in
and to the Collateral and shall, unless otherwise provided in this Agreement,
remain in full force and effect until the payment in full in cash of the Secured
Obligations. This Agreement shall be binding upon the Grantor, its transferees,
successors and assigns, and shall inure, together with the rights and remedies
of the Indenture Trustee hereunder, to the benefit of the Indenture Trustee, the
Holders of the Securities, the Pledge Trustee and their respective successors,
transferees and assigns.

<PAGE>   12

              (b) This Agreement (other than Grantor's obligations under
Sections 12 and 14) shall terminate on the later of payment in full in cash of
the Secured Obligations and July 27, 2002. At such time, the Indenture Trustee
shall, pursuant to an Issuer Order, direct the Pledge Trustee to promptly
transfer to the Grantor all of the Collateral hereunder that has not been sold,
disposed of, retained or applied by or on behalf of the Indenture Trustee in
accordance with the terms of this Agreement and the Indenture and take all other
actions that are necessary to release the security interest created by this
Agreement in and to the Collateral, including the execution and delivery of all
termination statements necessary to terminate any financing or continuation
statements filed with respect to the Collateral. Such transfer shall be without
warranty by or recourse to the Indenture Trustee in its capacity as such, except
as to the absence of any Liens on the Collateral created by or arising through
the Indenture Trustee, and shall be at the expense of the Grantor.

              Section 15.10. Survival of Representations and Covenants. All
representations, warranties and covenants of the Grantor contained herein shall
survive the execution and delivery of this Agreement.

              Section 15.11. Waivers. The Grantor, to the fullest extent
permitted by applicable law, waives presentment and demand for payment of any of
the Obligations, protest and notice of dishonor or default with respect to any
of the Obligations, and all other notices to which the Grantor might otherwise
be entitled, except as otherwise expressly provided herein or in the Indenture.

              Section 15.12. Authority of the Pledge Trustee and the Indenture
Trustee.

              (a) Each of the Pledge Trustee and Indenture Trustee shall have
and be entitled to exercise all powers hereunder that are specifically granted
to it by the terms hereof, together with such powers as are reasonably incident
thereto. Each of the Pledge Trustee and the Indenture Trustee may perform any of
its duties hereunder or in connection with the Collateral by or through agents
or employees and shall be entitled to retain counsel and to act in reliance upon
the advice of counsel concerning all such matters. Except as otherwise expressly
provided in this Agreement or the Indenture, neither the Indenture Trustee or
the Pledge Trustee nor any director, officer, employee, attorney or agent of the
Indenture Trustee or Pledge Trustee shall be liable to the Grantor for any
action taken or omitted to be taken by the Indenture Trustee or the Pledge
Trustee, as the case may be, hereunder, except for its own bad faith, gross
negligence or willful misconduct, and neither the Indenture Trustee nor the
Pledge Trustee shall be responsible for the validity, effectiveness or
sufficiency hereof or of any document or security furnished pursuant hereto. The
Indenture Trustee and the Pledge Trustee and their respective directors,
officers, employees, attorneys and agents shall be entitled to rely on any
communication, instrument or document reasonably believed by it or them to be
genuine and correct and to have been signed or sent by the proper person or
persons.

              (b) The Grantor acknowledges that the rights and responsibilities
of the Indenture Trustee under this Agreement with respect to any action taken
by the Indenture Trustee or the exercise or non-exercise by the Indenture
Trustee of any option, right, request, judgment or other right or remedy
provided for herein or resulting or arising out of this Agreement shall, as
between the Indenture Trustee and the Holders of the Securities, be governed by
the Indenture and by such other agreements with respect thereto as may exist
from time to time among them, but, as between the Indenture Trustee and the
Grantor, the Indenture Trustee shall be conclusively presumed to be acting as
agent for the Holders of the Securities with full and valid authority so to act
or refrain from acting, and the Grantor shall not be obligated or entitled to
make any inquiry respecting such authority.

              Section 15.13. Final Expression. This Agreement, together with the
Indenture and any other agreement executed in connection herewith, is intended
by the parties as a final expression of this Agreement and is intended as a
complete and exclusive statement of the terms and conditions thereof.

              Section 15.14. Rights of Holders of the Securities. No Holder of
Securities shall have any independent rights hereunder other than those rights
receive payments on the Securities granted to individual Holders of the
Securities pursuant to the Indenture; provided that nothing in this subsection
shall limit any rights granted to the Indenture Trustee under the Securities or
the Indenture.

AGENT FOR SERVICE OF PROCESS IN ANY SUIT, ACTION OR PROCEEDING WITH RESPECT TO

LAWS BROUGHT IN ANY FEDERAL OR STATE COURT LOCATED IN THE CITY OF NEW YORK AND
AGREES TO SUBMIT TO THE JURISDICTION OF ANY SUCH COURT.

              (d) THE GRANTOR AGREES THAT THE INDENTURE TRUSTEE SHALL, IN ITS
CAPACITY AS INDENTURE TRUSTEE OR IN THE NAME AND ON BEHALF OF ANY HOLDER OF
SECURITIES, HAVE THE RIGHT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW
(AND TO THE EXTENT THE INDENTURE TRUSTEE HAS RECEIVED INDEMNITY DEEMED
SATISFACTORY TO IT AND HAS AGREED TO DO SO), TO PROCEED AGAINST THE GRANTOR OR
THE COLLATERAL IN A COURT IN ANY LOCATION REASONABLY SELECTED IN GOOD FAITH (AND
HAVING PERSONAL OR IN REM JURISDICTION OVER THE GRANTOR OR THE COLLATERAL, AS

(EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT OR THE INDENTURE) THE INDENTURE
TRUSTEE IN ITS CAPACITY AS TRUSTEE, OR THE PLEDGE TRUSTEE IN ITS CAPACITY AS

OCCURRING IN CONNECTION THEREWITH, UNLESS IT IS DETERMINED BY A FINAL AND
NONAPPEALABLE JUDGMENT OF A COURT THAT IS BINDING ON THE INDENTURE TRUSTEE OR
SUCH HOLDER OF SECURITIES, AS THE CASE MAY BE, THAT SUCH LOSSES WERE THE RESULT
OF ACTS OR OMISSIONS ON THE PART OF THE INDENTURE TRUSTEE OR SUCH HOLDERS OF
SECURITIES, AS THE CASE MAY BE, CONSTITUTING BAD FAITH, GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.

SHELF REGISTRATION.

       The Company shall prepare and file or cause to be prepared and filed with
the SEC no later than a date which is ninety (90) days after the Issue Date (the
"Filing Deadline Date") a Registration Statement for an offering to be made on a
delayed or continuous basis pursuant to Rule 415 of the Securities Act (a "Shelf
Registration Statement") registering the resale from time to time by Holders
thereof of all of the Registrable Securities (the "Initial Shelf Registration
Statement"). The Initial Shelf Registration Statement shall be on Form S-3 or
another appropriate form permitting registration of such Registrable Securities
for resale by such Holders in accordance with the methods of distribution
reasonably elected by the Holders and set forth in the Initial Shelf
Registration Statement; provided, that in no event will such method(s) of
distribution take the form of an underwritten offering of the Registrable
Securities without the prior agreement of the Company. The Company shall use
reasonable efforts to cause the Initial Shelf Registration Statement to be
declared effective under the Securities Act by the date (the "Effectiveness
Deadline Date") that is one hundred and eighty (180) days after the Issue Date,
and to keep the Initial Shelf Registration Statement (or any Subsequent Shelf
Registration Statement) continuously effective under the Securities

                                       3
<PAGE>   4

Act until the expiration of the Effectiveness Period subject to the rights of
the Company under Section 3(i) to create a Deferral Period. At the time the
Initial Shelf Registration Statement is declared effective, each Holder that
became a Notice Holder on or prior to the date 10 Business Days prior to such
time of effectiveness shall be named as a selling securityholder in the Initial
Shelf Registration Statement and the related Prospectus in such a manner as to
permit such Holder to deliver such Prospectus to purchasers of Registrable
Securities in accordance with applicable law under ordinary circumstances,
subject to compliance with blue sky laws. None of the Company's securityholders
(other than the Holders of Registrable Securities) shall have the right to
include any of the Company's securities in the Shelf Registration Statement.

       If the Initial Shelf Registration Statement or any Subsequent Shelf
Registration Statement ceases to be effective other than during a Deferral
Period for any reason at any time during the Effectiveness Period, the Company
shall use reasonable efforts to obtain the prompt withdrawal of any order
suspending the effectiveness thereof, and in any event shall within thirty (30)
days of such cessation of effectiveness amend the Shelf Registration Statement
in a manner reasonably expected by the Company to obtain the withdrawal of the
order suspending the effectiveness thereof, or file an additional Shelf
Registration Statement covering all of the Securities that as of the date of
such filing are Registrable Securities (a "Subsequent Shelf Registration
Statement"). If a Subsequent Shelf Registration Statement is filed, the Company
shall use reasonable efforts to cause the Subsequent Shelf Registration
Statement to become effective as promptly as reasonably practicable after such
filing, unless during a Deferral Period, or, if filed during a Deferral Period,
after the expiration of a Deferral Period, and to keep such Registration
Statement (or subsequent Shelf Registration Statement) continuously effective
until the end of the Effectiveness Period.

       The Company shall supplement and amend the Shelf Registration Statement
if required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration Statement, if
required by the Securities Act or, to the extent to which the Company does not
reasonably object, as reasonably requested by the Initial Purchaser or by the
Trustee on behalf of the registered Holders.

       Each Holder of Registrable Securities agrees that if such Holder wishes
to sell Registrable Securities pursuant to a Shelf Registration Statement and
related Prospectus, it will do so only in accordance with this Section 2(d) and
Section 3(i). Each Holder of Registrable Securities wishing to sell Registrable
Securities pursuant to a Shelf Registration Statement and related Prospectus
agrees to deliver a Notice and Questionnaire to the Company at least five (5)
Business Days prior to any intended distribution of Registrable Securities under
the Shelf Registration Statement. From and after the date the Initial Shelf
Registration Statement is declared effective, the Company shall, as promptly as
reasonably practicable after the date a Notice and Questionnaire is delivered,
(i) if required by applicable law, file with the SEC a post-effective amendment
to the Shelf Registration Statement or prepare and, if required by applicable
law, file a supplement to the related Prospectus or a supplement or amendment to
any document incorporated therein by reference or file any other document
required by the SEC so that the Holder delivering such Notice and Questionnaire
is named as a selling securityholder in the Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of the Registrable Securities in accordance with
applicable law and, if the Company shall file a post-effective amendment to the
Shelf Registration Statement, use reasonable efforts to cause such
post-effective amendment to be declared effective under the Securities Act as
promptly as reasonably practicable; (ii) provide such Holder copies of any
documents filed pursuant to Section 2(d)(i); and (iii) notify such Holder as
promptly as reasonably practicable after the effectiveness under the Securities
Act of any post-effective amendment filed pursuant to Section 2(d)(i); provided,
that if such Notice and Questionnaire is delivered during a Deferral Period, the
Company shall so inform the Holder delivering such Notice and Questionnaire and
shall take the actions set forth in clauses (i), (ii) and (iii) above upon
expiration of the Deferral Period in accordance with Section 3(i), provided,
further, that if under applicable law the Company has more than one option as to
the type or manner of making any such filing, as set forth in an opinion of
nationally-recognized counsel experienced in such matters delivered by the
Holder to the Company, it will make the required filing or filings in the manner
or of a type that is reasonably expected to result in the earliest availability
of the Prospectus for effecting resales of Registrable Securities unless such
option would be adverse to the Company or result in increased costs.
Notwithstanding anything contained herein to the contrary, the Company shall be
under no obligation to name any Holder that is not a Notice Holder as a selling
securityholder in any Registration Statement or related Prospectus; provided,
however, that any Holder that becomes a Notice Holder pursuant to the provisions
of Section 2(d) of this Agreement (whether or not such Holder was a Notice
Holder at the

                                       4
<PAGE>   5

time the Registration Statement was initially declared effective) shall be named
as a selling securityholder in the Registration Statement or related Prospectus
subject to and in accordance with the requirements of this Section 2(d).

       The parties hereto agree that the Holders of Registrable Securities will
suffer damages, and that it would not be feasible to ascertain the extent of
such damages with precision, if (i) the Initial Shelf Registration Statement has
not been filed on or prior to the Filing Deadline Date, (ii) the Initial Shelf
Registration Statement has not been declared effective under the Securities Act
on or prior to the Effectiveness Deadline Date, or (iii) the aggregate duration
of Deferral Periods in any period exceeds the number of days permitted in
respect of such period pursuant to Section 3(i) hereof (each of the events of a
type described in any of the foregoing clauses (i) through (iii) are
individually referred to herein as an "Event," and the Filing Deadline Date in
the case of clause (i), the Effectiveness Deadline Date in the case of clause
(ii), and the date on which the aggregate duration of Deferral Periods in any
period exceeds the number of days permitted by Section 3(i) hereof in the case
of clause (iii), being referred to herein as an "Event Date"). Events shall be
deemed to continue until the "Event Termination Date," which shall be the
following dates with respect to the respective types of Events: the date the
Initial Shelf Registration Statement is filed in the case of an Event of the
type described in clause (i), the date the Initial Shelf Registration Statement
is declared effective under the Securities Act in the case of an Event of the
type described in clause (ii), termination of the Deferral Period that caused
the limit on the aggregate duration of Deferral Periods in a period set forth in
Section 3(i) to be exceeded in the case of the commencement of an Event of the
type described in clause (iii).

       Accordingly, commencing on (and including) any Event Date and ending on
(but excluding) the next date on which there are no Events that have occurred
and are continuing (a "Damages Accrual Period"), the Company agrees to pay, as
liquidated damages and not as a penalty, an amount (the "Liquidated Damages
Amount"), payable on the Damages Payment Dates to Record Holders of then
outstanding LYONs that are Registrable Securities, of then outstanding shares of
Underlying Common Stock issued upon conversion of LYONs that are Registrable
Securities, if any, as the case may be, accruing, for each portion of such
Damages Accrual Period beginning on and including a Damages Payment Date (or, in
respect of the first time that the Liquidation Damages Amount is to be paid to
Holders on a Damages Payment Date as a result of the occurrence of any
particular Event occurring since the most recent Damages Payment Event, from the
Event Date) and ending on but excluding the first to occur of (A) the date of
the end of the Damages Accrual Period or (B) the next Damages Payment Date, at a
rate per annum equal to one-quarter of one percent (0.25%) for the first 90-day
period from the Event Date, and thereafter at a rate per annum equal to one-half
of one percent (0.5%) of the aggregate Applicable Principal Amount of such LYONs
to the Record Holder of the then outstanding LYONs that are Registrable
Securities or the aggregate Applicable Conversion Price of the shares of
Underlying Common Stock to the Record Holder of the then outstanding shares of
Underlying Common Stock that are Registrable Securities, as the case may be, in
each case determined as of the Business Day immediately preceding the next
Damages Payment Date; provided, that any Liquidated Damages Amount accrued with
respect to any LYON or portion thereof called for redemption on a redemption
date or converted into Underlying Common Stock on a conversion date prior to the
Damages Payment Date, shall, in any such event, be paid instead to the Holder
who submitted such LYON or portion thereof for redemption or conversion on the
applicable redemption date or conversion date, as the case may be, on such date
(or promptly following the conversion date, in the case of conversion).
Notwithstanding the foregoing, no Liquidated Damages Amounts shall accrue as to
any Registrable Security from and after the earlier of (x) the date such
security is no longer a Registrable Security and (y) expiration of the
Effectiveness Period. The rate of accrual of the Liquidated Damages Amount with
respect to any period shall not exceed the rate provided for in this paragraph
notwithstanding the occurrence of multiple concurrent Events. Following the cure
of all Events requiring the payment by the Company of Liquidated Damages Amounts
to the Holders of Registrable Securities pursuant to this Section, the accrual
of Liquidated Damages Amounts will cease (without in any way limiting the effect
of any subsequent Event requiring the payment of the Liquidated Damages Amount
by the Company ) and accrued and unpaid Liquidated Damages will be paid in cash
to the date of such cure to the Holder of record on the immediately succeeding
Damages Payment Date.

       The Trustee shall be entitled, on behalf of Holders of LYONs or
Underlying Common Stock, to seek any available remedy for the enforcement of
this Agreement, including for the payment of any Liquidated Damages Amount.
Notwithstanding the foregoing, the parties agree that the sole remedy for a
violation of the terms of this Agreement with respect to which liquidated
damages are expressly provided shall be such liquidated damages.

                                       5
<PAGE>   6

       All of the Company's obligations set forth in this Section 2(e) that are
outstanding with respect to any Registrable Security at the time such Security
ceases to be a Registrable Security shall survive until such time as all such
obligations with respect to such security have been satisfied in full
(notwithstanding termination of this Agreement pursuant to Section 8(j)).

       The parties hereto agree that the liquidated damages provided for in this
Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by Holders of Registrable Securities by reason of the failure of the
Shelf Registration Statement to be filed or declared effective or available for
effecting resales of Registrable Securities in accordance with the provisions
hereof.

Registration Procedures. In connection with the registration obligations of the
Company under Section 2 hereof, the Company shall:

       Before filing any Registration Statement or Prospectus or any amendments
or supplements thereto with the SEC, furnish to the Initial Purchaser copies of
all such documents proposed to be filed and use reasonable efforts to reflect in
each such document when so filed with the SEC such comments as the Initial
Purchaser reasonably shall propose.

       Prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the applicable period
specified in Section 2(a); cause the related Prospectus to be supplemented by
any required Prospectus supplement, and as so supplemented to be filed pursuant
to Rule 424 (or any similar provisions then in force) under the Securities Act;
and use reasonable efforts to comply with the provisions of the Securities Act
applicable to it with respect to the disposition of all securities covered by
such Registration Statement during the Effectiveness Period in accordance with
the intended methods of disposition by the sellers thereof set forth in such
Registration Statement as so amended or such Prospectus as so supplemented.

       As promptly as reasonably practicable give notice to the Notice Holders
and the Initial Purchaser (i) when any Prospectus, Prospectus supplement,
Registration Statement or post-effective amendment to a Registration Statement
has been filed with the SEC and, with respect to a Registration Statement or any
post-effective amendment, when the same has been declared effective, by release
made to Reuters Economic Services and Bloomberg Business News or other
reasonable means of distribution. (ii) of any request, following the
effectiveness of the Initial Shelf Registration Statement under the Securities
Act, by the SEC or any other federal or state governmental authority for
amendments or supplements to any Registration Statement or related Prospectus or
for additional information, (iii) of the issuance by the SEC or any other
federal or state governmental authority of any stop order suspending the
effectiveness of any Registration Statement or the initiation or threatening of
any proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of (but not the nature of or details concerning)
a Material Event (provided, however, that no notice by the Company shall be
required pursuant to this clause (v) in the event that the Company either
promptly files a Prospectus supplement to update the Prospectus or a Form 8-K or
other appropriate Exchange Act report that is incorporated by reference into the
Registration Statement, which, in either case, contains the requisite
information with respect to such Material Event that results in such
Registration Statement no longer containing any untrue statement of material
fact or omitting to state a material fact necessary to make the statements
contained therein not misleading) and (vi) of the determination by the Company
that a post-effective amendment to a Registration Statement will be filed with
the SEC, which notice may, at the discretion of the Company (or as required
pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which
event the provisions of Section 3(i) shall apply.

       Use reasonable efforts to obtain the withdrawal of any order suspending
the effectiveness of a Registration Statement or the lifting of any suspension
of the qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction in which they have been qualified for
sale, in either case at the earliest possible moment or, if a Deferral Period is
in effect, at the earliest possible moment after the Deferral Period.

                                       6
<PAGE>   7

       If reasonably requested by the Initial Purchaser or any Notice Holder, as
promptly as reasonably practicable incorporate in a Prospectus supplement or
post-effective amendment to a Registration Statement such information as the
Initial Purchaser or such Notice Holder shall, on the basis of an opinion of
nationally-recognized counsel experienced in such matters, determine to be
required to be included therein by applicable law and make any required filings
of such Prospectus supplement or such post-effective amendment; provided, that
the Company shall not be required to take any actions under this Section 3(e)
that are not, in the reasonable opinion of counsel for the Company, in
compliance with applicable law.

       As promptly as reasonably practicable furnish to each Notice Holder and
the Initial Purchaser, upon their request and without charge, at least one (1)
conformed copy of the Registration Statement and any amendment thereto,
including financial statements, but excluding schedules, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits
(unless requested in writing to the Company by such Notice Holder or the Initial
Purchaser, as the case may be).

       During the Effectiveness Period, deliver to each Notice Holder in
connection with any sale of Registrable Securities pursuant to a Registration
Statement, without charge, as many copies of the Prospectus or Prospectuses
relating to such Registrable Securities (including each preliminary prospectus)
and any amendment or supplement thereto as such Notice Holder may reasonably
request; and the Company hereby consents (except during such periods that a
Deferral Notice is outstanding and has not been revoked) to the use of such
Prospectus or each amendment or supplement thereto by each Notice Holder in
connection with any offering and sale of the Registrable Securities covered by
such Prospectus or any amendment or supplement thereto in the manner set forth
therein.

       Subject to Section 3(i), prior to any public offering of the Registrable
Securities pursuant to the Shelf Registration Statement, use reasonable efforts
to register or qualify or cooperate with the Notice Holders in connection with
the registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any Notice Holder reasonably requests in writing (which request may be included
in the Notice and Questionnaire) it being agreed that no such registration or
qualification will be made unless so requested; prior to any public offering of
the Registrable Securities pursuant to the Shelf Registration Statement, use
reasonable efforts to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period in connection with such
Notice Holder's offer and sale of Registrable Securities pursuant to such
registration or qualification (or exemption therefrom) and do any and all other
acts or things necessary to enable the disposition in such jurisdictions of such
Registrable Securities in the manner set forth in the relevant Registration
Statement and the related Prospectus; provided, that the Company will not be
required to (i) qualify as a foreign corporation or as a dealer in securities in
any jurisdiction where it is not otherwise qualified but for this Agreement or
(ii) take any action that would subject it to general service of process in
suits or to taxation in any such jurisdiction where it is not then so subject.

       Upon (A) the issuance by the SEC of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of
proceedings with respect to the Shelf Registration Statement under Section 8(d)
or 8(e) of the Securities Act, (B) the occurrence of any event or the existence
of any fact (a "Material Event") as a result of which any Registration Statement
shall 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, or any Prospectus shall 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, or (C) the occurrence or existence
of any corporate development that, in the discretion of the Company, makes it
appropriate to suspend the availability of the Shelf Registration Statement and
the related Prospectus, (i) in the case of clause (B) above, subject to the next
sentence, as promptly as reasonably practicable prepare and file a
post-effective amendment to such Registration Statement or a supplement to the
related Prospectus or any document incorporated therein by reference or file any
other required document that would be incorporated by reference into such
Registration Statement and Prospectus so that such Registration Statement does
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 such Prospectus does 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, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder,
and, in the case of a post-effective amendment to a Registration

                                       7
<PAGE>   8

Statement, subject to the next sentence, use reasonable efforts to cause it to
be declared effective as promptly as is reasonably practicable, and (ii) give
notice to the Notice Holders that the availability of the Shelf Registration
Statement is suspended (a "Deferral Notice") and, upon receipt of any Deferral
Notice, each Notice Holder agrees not to sell any Registrable Securities
pursuant to the Registration Statement until such Notice Holder's receipt of
copies of the supplemented or amended Prospectus provided for in clause (i)
above, or until it is advised in writing by the Company that the Prospectus may
be used, and has received copies of any additional or supplemental filings that
are incorporated or deemed incorporated by reference in such Prospectus. The
Company will use all reasonable efforts to ensure that the use of the Prospectus
may be resumed (x) in the case of clause (A) above, as promptly as reasonably
practicable, (y) in the case of clause (B) above, as soon as, in the sole
judgment of the Company, public disclosure of such Material Event would not be
prejudicial to or contrary to the interests of the Company or, if necessary to
avoid unreasonable burden or expense, as soon as reasonably practicable
thereafter and (z) in the case of clause (C) above, as soon as, in the
discretion of the Company, such suspension is no longer appropriate. The period
during which the availability of the Registration Statement and any Prospectus
is suspended (the "Deferral Period") shall, without the Company incurring any
obligation to pay liquidated damages pursuant to Section 2(e), not exceed
forty-five (45) days in any three (3) month period or ninety (90) days in any
twelve (12) month period.

       If reasonably requested in writing in connection with a disposition of
Registrable Securities pursuant to a Registration Statement, make reasonably
available for inspection during normal business hours by a representative for
the Notice Holders of such Registrable Securities and any broker-dealers,
attorneys and accountants retained by such Notice Holders, all relevant
financial and other records, pertinent corporate documents and properties of the
Company and its subsidiaries, and cause the appropriate executive officers,
directors and designated employees of the Company and its subsidiaries to make
reasonably available for inspection during normal business hours all relevant
information reasonably requested by such representative for the Notice Holders
or any such broker-dealers, attorneys or accountants in connection with such
disposition, in each case as is customary for similar "due diligence"
examinations; provided, however, that such persons shall first agree in writing
with the Company that any information that is reasonably designated by the
Company in writing as confidential at the time of delivery of such information
shall be kept confidential by such persons and shall be used solely for the
purposes of exercising rights under this Agreement and such person shall comply
with applicable securities laws, unless (i) disclosure of such information is
required by court or administrative order or is necessary to respond to
inquiries of regulatory authorities, (ii) disclosure of such information is
required by law (including any disclosure requirements pursuant to federal
securities laws in connection with the filing of any Registration Statement or
the use of any Prospectus referred to in this Agreement), (iii) such information
becomes generally available to the public other than as a result of a disclosure
or failure to safeguard by any such person or (iv) such information becomes
available to any such person from a source other than the Company and such
source is not bound by a confidentiality agreement; and provided further, that
the foregoing inspection and information gathering shall, to the greatest extent
possible, be coordinated on behalf of all the Notice Holders and the other
parties entitled thereto by the counsel referred to in Section 5.

       Comply with all applicable rules and regulations of the SEC and make
generally available to its securityholders earning statements (which need not be
audited) 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 90 days after the end of the first 12-month period constituting a
fiscal year commencing on the first day of the first fiscal quarter of the first
fiscal year of the Company commencing after the effective date of a Registration
Statement, which statements shall cover said 12-month periods.

       Cooperate with each Notice Holder to facilitate the timely preparation
and delivery of certificates representing Registrable Securities sold pursuant
to a Registration Statement, and cause such Registrable Securities to be in such
denominations as are permitted by the Indenture and registered in such names as
such Notice Holder may request in writing at least two Business Days prior to
any sale of such Registrable Securities.

       Provide a CUSIP number for all Registrable Securities covered by each
Registration Statement not later than the effective date of such Registration
Statement and provide the Trustee for the LYONs and the transfer agent for the
Common Stock with certificates for the Registrable Securities that are in a form
eligible for deposit with The Depository Trust Company.

                                       8
<PAGE>   9

       Make reasonable effort to provide such information as is required for any
filings required to be made with the National Association of Securities Dealers,
Inc.

       Upon (i) the filing of the Initial Shelf Registration Statement and (ii)
the effectiveness of the Initial Shelf Registration Statement, announce the
same, in each case by release to Reuters Economic Services and Bloomberg
Business News or other reasonable means of distribution.

       Enter into such customary agreements and take all such other reasonable
necessary actions in connection therewith (including those reasonably requested
by the holders of a majority of the Registrable Securities being sold) in order
to expedite or facilitate disposition of such Registrable Securities; provided
that the Company shall not be required to take any action in connection with an
underwritten offering without its consent; and

       Cause the Indenture to be qualified under the TIA not later than the
effective date of any Registration Statement; and in connection therewith,
cooperate with the Trustee to effect such changes to the Indenture as may be
required for the Indenture to be so qualified in accordance with the terms of
the TIA and execute, and use reasonable efforts to cause the 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 the Indenture to be so
qualified in a timely manner.

       Holder's Obligations. Each Holder agrees, by acquisition of the
Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Registration
Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Company with a Notice and Questionnaire as required pursuant to
Section 2(d) hereof (including the information required to be included in such
Notice and Questionnaire) and the information set forth in the next sentence.
Each Notice Holder agrees promptly to furnish to the Company all information
required to be disclosed in order to make the information previously furnished
to the Company by such Notice Holder not misleading and any other information
regarding such Notice Holder and the distribution of such Registrable Securities
as may be required to be disclosed in the Registration Statement under
applicable law or pursuant to SEC comments. Each Holder further agrees,
following termination of the Effectiveness Period, to notify the Company within
10 business days of request, of the amount of Registrable Securities sold
pursuant to the Registration Statement and, in the absence of a response, the
Company may assume that all of the Holder's Registrable Securities were so sold.

       Registration Expenses. The Company shall bear all fees and expenses
incurred in connection with the performance by the Company of its obligations
under Sections 2 and 3 of this Agreement whether or not any of the Registration
Statements are declared effective. Such fees and expenses shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (x) with respect to filings required to be made with the
National Association of Securities Dealers, Inc. and (y) of compliance with
federal and state securities or Blue Sky laws to the extent such filings or
compliance are required pursuant to this Agreement (including, without
limitation, reasonable fees and disbursements of the counsel specified in the
next sentence in connection with Blue Sky qualifications of the Registrable
Securities under the laws of such jurisdictions as the Notice Holders of a
majority of the Registrable Securities being sold pursuant to a Registration
Statement may designate)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities in a
form eligible for deposit with The Depository Trust Company), (iii) duplication
expenses relating to copies of any Registration Statement or Prospectus
delivered to any Holders hereunder, (iv) fees and disbursements of counsel for
the Company in connection with the Shelf Registration Statement, and (v)
reasonable fees and disbursements of the Trustee and its counsel and of the
registrar and transfer agent for the Common Stock. In addition, the Company
shall bear or reimburse the Notice Holders for the fees and disbursements of one
firm of legal counsel for the Holders, which shall, upon the written consent of
the Initial Purchaser (which shall not be unreasonably withheld), be a
nationally recognized law firm experienced in securities law matters designated
by the Company. In addition, the Company shall pay the internal expenses of the
Company (including, without limitation, all salaries and expenses of officers
and employees performing legal or accounting duties), the expense of any annual
audit, the fees and expenses incurred in connection with the listing of the
Registrable Securities on any securities exchange on which the same securities
of the Company are then listed and the fees and expenses of any person,
including special experts, retained by the Company.

INDEMNIFICATION; CONTRIBUTION.

                                       9
<PAGE>   10

       The Company agrees to indemnify and hold harmless the Initial Purchaser
and each Holder of Registrable Securities and each person, if any, who controls
the Initial Purchaser or any Holder of Registrable Securities within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act, as
follows:

              (a) against any and all loss, liability, claim, damage and expense
       whatsoever, as incurred, arising out of any untrue statement or alleged
       untrue statement of a material fact contained in the Registration
       Statement (or any amendment thereto), or the omission or alleged omission
       therefrom of a material fact required to be stated therein or necessary
       to make the statements therein not misleading or arising out of any
       untrue statement or alleged untrue statement of a material fact included
       in any preliminary prospectus or the Prospectus (or any amendment or
       supplement thereto), or the omission or alleged omission therefrom of a
       material fact necessary in order to make the statements therein, in the
       light of the circumstances under which they were made, not misleading;

              (b) against any and all loss, liability, claim, damage and expense
       whatsoever, as incurred, to the extent of the aggregate amount paid in
       settlement of any litigation, or any investigation or proceeding by any
       governmental agency or body, commenced or threatened, or of any claim
       whatsoever based upon any such untrue statement or omission, or any such
       alleged untrue statement or omission, provided that (subject to Section
       6(d) below) any such settlement is effected with the prior written
       consent of the Company; and

              (c) against any and all expense whatsoever, as incurred (including
       the fees and disbursements of counsel chosen by the Initial Purchaser),
       reasonably incurred in investigating, preparing or defending against any
       litigation, or any investigation or proceeding by any governmental agency
       or body, commenced or threatened, or any claim whatsoever based upon any
       such untrue statement or omission, or any such alleged untrue statement
       or omission, to the extent that any such expense is not paid under (i) or
       (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Initial Purchaser, such Holder of Registrable Securities (which also
acknowledges the indemnity provisions herein) or any person, if any, who
controls the Initial Purchaser or any such Holder of Registrable Securities
expressly for use in the Registration Statement (or any amendment thereto), or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); provided, further, that this indemnity agreement shall not apply to
any loss, liability, claim, damage or expense (1) arising from an offer or sale
of Registrable Securities occurring during a Deferral Period, if a Deferral
Notice was given to such Notice Holder in accordance with Section 8(b), or (2)
if the Holder fails to deliver at or prior to the written confirmation of sale,
the most recent Prospectus, as amended or supplemented, and such Prospectus, as
amended or supplemented, would have corrected such untrue statement or omission
or alleged untrue statement or omission of a material fact.

       In connection with any Shelf Registration in which a Holder, including,
without limitation, the Initial Purchaser, of Registrable Securities is
participating, in furnishing information relating to such Holder of Registrable
Securities to the Company in writing expressly for use in such Registration
Statement, any preliminary prospectus, the Prospectus or any amendments or
supplements thereto, the Holders of such Registrable Securities agree, severally
and not jointly, to indemnify and hold harmless the Initial Purchaser and each
person, if any, who controls the Initial Purchaser within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act and the
Company, and each person, if any, who controls the Company within the meaning of
either such Section, against any and all loss, liability, claim, damage and
expense described in the indemnity contained in subsection (a) of this Section,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto), or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company by or on behalf of such Holder of
Registrable Securities (which also acknowledges the indemnity provisions herein)
or any person, if any, who controls any such Holder of Registrable Securities
expressly for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

                                       10
<PAGE>   11

       The Initial Purchaser agrees to indemnify and hold harmless the Company,
the Holders of Registrable Securities, and each person, if any, who controls the
Company or any Holder of Registrable Securities within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act against any
and all loss, liability, claim, damage and expense described in the indemnity
contained in subsection (a) of this Section, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Registration Statement (or any amendment thereto), or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by the Initial Purchaser expressly for use in the Registration
Statement (or any amendment thereto) or such preliminary prospectus or the
Prospectus (or any amendment or supplement thereto).

       Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement. The indemnifying party, upon
request of the indemnified party, shall retain counsel reasonably satisfactory
to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party 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 party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for (a) the fees and expenses of more than one separate firm (in
addition to any local counsel), whose fees must be reasonable, for the Initial
Purchaser, Holders of Registrable Securities, and all persons, if any, who
control the Initial Purchaser or Holders of Registrable Securities within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act, collectively (b) the fees and expenses of more than one separate firm (in
addition to any local counsel), whose fees must be reasonable, for the Company
and each person, if any, who controls the Company within the meaning of either
such Section, and that all fees and expenses payable under (a) and (b) above
shall be reimbursed as they are incurred. In the case of any such separate firm
for the Initial Purchaser, Holders of Registrable Securities, and control
persons of the Initial Purchaser and Holders of Registrable Securities, such
firm shall be designated in writing by the Initial Purchaser. In the case of any
such separate firm for the Company and control persons of the Company, such firm
shall be designated in writing by the Company. The indemnifying party 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 party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. No indemnifying party shall, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 6 (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

       If at any time an indemnified party shall have requested an indemnifying
party to reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 6(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of aforesaid request, (ii) such indemnifying party shall have
received notice of the terms of such settlement at least 30 days prior to such
settlement being entered into and (iii) such indemnifying party shall not have
reimbursed such indemnified party in accordance with such request prior to the
date of such settlement; provided, that an indemnifying party shall not be
liable for any such settlement effected without its consent if such indemnifying
party (1) reimburses such indemnified party in accordance with such request to
the extent it considers such request to be reasonable and (2) provides written
notice to the indemnified party substantiating the unpaid balance as
unreasonable, in each case prior to the date of such settlement.

                                       11
<PAGE>   12

       If the indemnification to which an indemnified party is entitled under
this Section 6 is for any reason unavailable to or insufficient although
applicable in accordance with its terms to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the indemnifying party or parties on the one hand and of
the indemnified party on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

       The relative fault of the Company on the one hand and the Holders of the
Registrable Securities or the Initial Purchaser on the other hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or by the
Holder of the Registrable Securities or the Initial Purchaser and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

       The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(e) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 6(e). The
aggregate amount of losses, liabilities, claims, damages, and expenses incurred
by an indemnified party and referred to above in this Section 6(e) shall be
deemed to include any out-of-pocket legal or other expenses reasonably incurred
by such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

       Notwithstanding the provisions of this Section 6, neither the Holder of
any Registrable Securities nor the Initial Purchaser, shall be required to
indemnify or contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by such Holder of Registrable
Securities or by the Initial Purchaser, as the case may be, and distributed to
the public were offered to the public exceeds the amount of any damages that
such Holder of Registrable Securities or the Initial Purchaser 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.

       For purposes of this Section 6(e), each person, if any, who controls the
Initial Purchaser or any Holder of Registrable Securities within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as the Initial Purchaser or such Holder, and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Company, as the case may be.

Information Requirements. The Company covenants that, if at any time before the
end of the Effectiveness Period the Company is not subject to the reporting
requirements of the Exchange Act, the Company will cooperate with any Holder of
Registrable Securities and take such further reasonable action as any Holder of
Registrable Securities may reasonably request in writing (including, without
limitation, making such reasonable representations as any such Holder may
reasonably request), all to the extent required from time to time to enable such
Holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144 and Rule 144A
under the Securities Act and customarily taken in connection with sales pursuant
to such exemptions. Upon the written request of any Holder of Registrable
Securities, the Company shall deliver to such Holder a written statement as to
whether the Company has complied with such filing requirements, unless such a
statement has been included in the Company's most recent report required to be
filed and filed pursuant to Section 13 or Section 15(d) of Exchange Act.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities under any section of the
Exchange Act.

Miscellaneous; No Conflicting Agreements. The Company is not, as of the date
hereof, a party to, nor shall the Company, on or after the date of this
Agreement, enter into, any agreement with respect to its securities that

                                       12
<PAGE>   13

conflicts with the rights granted to the Holders of Registrable Securities in
this Agreement. The Company represents and warrants that the rights granted to
the Holders of Registrable Securities hereunder do not in any way conflict with
the rights granted to the holders of the Company's other issued and outstanding
securities under any other agreements.

Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless the Company has obtained the written consent of Holders of a majority of
the then outstanding Underlying Common Stock constituting Registrable Securities
(with Holders of LYONs deemed to be the Holders, for purposes of this Section,
of the number of outstanding shares of Underlying Common Stock into which such
LYONs are or would be convertible or exchangeable as of the date on which such
consent is requested). 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 Securities whose securities
are being sold pursuant to a Registration Statement and that does not directly
or indirectly affect the rights of other Holders of Registrable Securities may
be given by Holders of at least a majority of the Registrable Securities 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. Each
Holder of Registrable Securities outstanding at the time of any such amendment,
modification, supplement, waiver or consent or thereafter shall be bound by any
such amendment, modification, supplement, waiver or consent effected pursuant to
this Section 8(a), whether or not any notice, writing or marking indicating such
amendment, modification, supplement, waiver or consent appears on the
Registrable Securities or is delivered to such Holder.

Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand delivery, by telecopier, by courier
guaranteeing overnight delivery or by first-class mail, return receipt
requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after
being deposited with such courier, if made by overnight courier or (iv) on the
date indicated on the notice of receipt, if made by first-class mail, to the

Approval of Holders. Whenever the consent or approval of Holders of a specified
percentage of Registrable Securities is required hereunder, Registrable
Securities held by the Company or its affiliates (as such term is defined in
Rule 405 under the Securities Act) (other than the Initial Purchaser or
subsequent Holders of Registrable Securities if such subsequent Holders are
deemed to be such affiliates solely by reason of their holdings of such
Registrable Securities) shall not be counted in determining whether such consent
or approval was given by the Holders of such required percentage.

Successors and Assigns. Any person who purchases any Registrable Securities from
the Initial Purchaser shall be deemed, for purposes of this Agreement, to be an
assignee of the Initial Purchaser. This Agreement shall inure to the benefit of
and be binding upon the successors and assigns of each of the parties and shall
inure to the benefit of and be binding upon each Holder of any Registrable
Securities.

Counterparts. This Agreement may be executed in any number of counterparts and
by the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be original and all of which taken together shall constitute
one and the same agreement.

Headings. The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof.

Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK.

Severability. If any term, provision, covenant or restriction of this Agreement
is held to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated
thereby, and the parties hereto shall use their best efforts to find and employ
an alternative means to achieve the same or substantially the same result as
that contemplated by such term, provision, covenant or restriction, it being
intended that all of the rights and privileges of the parties shall be
enforceable to the fullest extent permitted by law.

Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and is intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein and the registration rights granted by the
Company with respect to the Registrable Securities. Except as provided in the
Purchase Agreement, there are no restrictions, promises, warranties or
undertakings, other than those set forth or referred to herein, with respect to
the registration rights granted by the Company with respect to the Registrable
Securities. This Agreement supersedes all prior agreements and undertakings
among the parties solely with respect to such registration rights.

Termination. This Agreement and the obligations of the parties hereunder shall
terminate upon the end of the Effectiveness Period, except for any liabilities
or obligations under Sections 4, 5 or 6 hereof and the obligations to make
payments of and provide for Liquidated Damages under Section 2(e) hereof to the

which shall remain in effect in accordance with its terms.
