         effective but, during the Shelf Registration Period, shall thereafter
         cease to be effective or fail to be usable for its intended purpose or
         if the Company suspends the use of the Prospectus forming a part
         thereof; except under the circumstances and for the time periods set
         forth in Section 3(c) above,

(each such event referred to in foregoing clauses (i) through (iii), a
"REGISTRATION DEFAULT"), the Company hereby agrees to pay additional interest
("SPECIAL INTEREST") with respect to the Transfer Restricted Securities from and
including the day following the Registration Default to but excluding the day on
which the Registration Default has been cured, which shall accrue as follows:

<PAGE>

                  (A) in respect of the Notes, to each Holder of Notes at the
         rate of an additional 0.5% per year of the principal amount of the
         Notes held by such Holders; and

                  (B) in respect of any shares of Common Stock issued upon
         conversion of Notes, to each holder of such shares of Common Stock at
         the rate of an additional 0.5% per year of the principal amount of the
         Notes formerly held by such holders that were converted into such
         shares of Common Stock.

         (e) All accrued Special Interest shall be paid in arrears to Holders by
the Company on each Damages Payment Date by wire transfer of immediately
available funds pursuant to the notice requirements of Section 4(l). Following
the cure of all Registration Defaults relating to any particular Note or share
of Common Stock issued upon conversion of Notes, the accrual of Special Interest
with respect to such Note or such share of Common Stock shall cease.

SECTION 4 REGISTRATION PROCEDURES

         In connection with any Shelf Registration Statement, the following

(iii) except as permitted by Section 3, any Prospectus forming part of any Shelf
Registration Statement, and any amendment or supplement to such Prospectus, does
not include an untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements, in the light of the
circumstances under which they were made, not misleading.

         (b) (1) The Company shall advise the Initial Purchasers and the Holders
of Transfer Restricted Securities named in any Shelf Registration Statement that
have provided in writing to the Company a telephone or facsimile number and
address for notices, and, if requested by the Initial Purchasers or any such
Holder, confirm such advice in writing when a Shelf Registration Statement and
any amendment thereto has been filed with the Commission and when the Shelf
Registration Statement or any post-effective amendment thereto has become
effective.

of Transfer Restricted Securities named in any Shelf Registration Statement,
which have provided in writing to the Company a telephone or facsimile number

<PAGE>

                  (ii) of the initiation by the Commission of proceedings

                  (iv) of the receipt by the Company of any notification with
         respect to the suspension of the qualification of the securities

                  (v) of the existence of any fact and the happening of any
         event (including, without limitation, pending negotiations relating to,
         or the consummation of, a transaction or the occurrence of any event
         which would require additional disclosure of material non-public
         information by the Company in the Shelf Registration Statement as to
         which the Company has a bona fide business purpose for preserving
         confidential or which renders the Company unable to comply with
         Commission requirements) that, in the opinion of the Company, makes
         untrue any statement of a material fact made in its Shelf Registration
         Statement, the Prospectus or any amendment or supplement thereto or any
         document incorporated by reference therein or requires the making of

         necessary to make the statements therein (in the case of the
         Prospectus, in light of the circumstances under which they were made)
         not misleading.

         Such advice may be accompanied by an instruction to suspend the use of

thereto as such Holder may reasonably request; subject to any notice by the
Company in accordance with Section 5(b) hereof, the Company consents to the use
of the Prospectus or any amendment or supplement thereto by each of the selling
Holders for the purposes of offering and resale of the Transfer Restricted
Securities

                                       7

covered by the Prospectus in accordance with the applicable regulations

their respective counsel in connection with the registration or qualification of
such Transfer Restricted Securities for offer and sale under the securities or
blue sky laws of such jurisdictions of the United States as any such Holders
reasonably request in writing not later than the date that is five business days
prior to the date upon which this Agreement specifies that the Shelf
Registration Statement shall become effective; PROVIDED, HOWEVER, that the
Company will not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to take any action which would
subject it to general or unlimited service of process or to taxation in any such
jurisdiction where it is not then so subject.

         (g) The Company shall cooperate with the Holders of Transfer Restricted
Securities to facilitate the timely preparation and delivery of certificates
representing Transfer Restricted Securities to be sold pursuant to any Shelf
Registration Statement free of any restrictive legends and in such denominations
and registered in such names as Holders may request in writing.

         (h) Except to the extent otherwise permitted under Section 3, upon the
occurrence of any event contemplated by paragraph 4(b)(2)(v) hereof, the Company
shall promptly prepare a post-effective amendment to any Shelf Registration
Statement or an amendment or supplement to the related Prospectus or file any
other required document so that as thereafter delivered to purchasers of the
Transfer Restricted Securities covered thereby, the Prospectus will not include
an untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

         (i) Not later than the effective date of any such Shelf Registration
Statement hereunder, the Company shall cause to be provided a CUSIP number for

applicable trustee with certificates for such Notes in a form eligible for
deposit with The Depository Trust Company.

         (j) The Company shall make generally available to its security holders
in a regular filing on Form 10-Q or 10-K an earnings statement satisfying the

Statement.

         (l) The Company may require each Holder of Transfer Restricted
Securities, which are to be sold pursuant to any Shelf Registration Statement,
to furnish to the Company within 20 business days after written request for such
information has been made by the Company, such information regarding the Holder
and the distribution of such securities as the Company may from time to time
reasonably require for inclusion in such Shelf Registration Statement and such

                                       8

<PAGE>

other information as may be necessary or advisable in the reasonable opinion of
the Company and its counsel, in connection with such Shelf Registration
Statement. No Holder of Transfer Restricted Securities shall be entitled to the
benefit of any Special Interest (as set forth in the Notes) under the Indenture
and the Notes or be entitled to use the Prospectus unless and until such Holder

information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

         (m) The Company shall, if requested, promptly incorporate in a
Prospectus supplement or post-effective amendment to a Shelf Registration
Statement, such information as the Majority Holders reasonably agree should be
included therein in order to effect their distribution of the Notes and shall
make all required filings of such Prospectus supplement or post-effective
amendment as soon as notified of the matters to be incorporated in such
Prospectus supplement or post-effective amendment; PROVIDED, HOWEVER, that the
Company shall not be required to take any action pursuant to this Section 4(m)
that would, in the opinion of counsel for the Company, violate applicable law or
to include information the disclosure of which at the time would have a material
adverse effect on the business or operations of the Company and/or its
subsidiaries, as determined in good faith by the Company.

         (n) In the case of any Shelf Registration Statement, the Company shall:

                  (i) make available at reasonable times prior to the
         effectiveness of the related Shelf Registration Statement for
         inspection by representatives of the Holders of Transfer Restricted
         Securities to be registered thereunder and any attorney, accountant or
         other agent retained by such Holders, at the office where normally kept
         during normal business hours, all financial and other records,
         pertinent corporate documents and properties of the Company and its
         subsidiaries, and cause the Company's officers, directors and employees
         to supply all relevant information reasonably requested by the Holders'
         attorneys, accountants or other agents in connection with any such
         Shelf Registration Statement as is customary for similar due diligence
         examinations; PROVIDED, HOWEVER, that the foregoing inspection and
         information gathering shall be coordinated by one counsel designated by
         the Holders and that such persons shall first agree in writing with the
         Company that any information that is designated in writing by the
         Company, in good faith, as confidential at the time of delivery of such
         information shall be kept confidential by such person, unless such
         disclosure is made in connection with a court proceeding or required by
         law, or such information becomes available to the public generally or
         through a third party without an accompanying obligation of
         confidentiality; and

                  (ii) upon the effectiveness of such Shelf Registration
         Statement and the effectiveness of each post-effective amendment
         thereto, deliver such documents and certificates as may be reasonably
         requested by the Majority Holders, including those to evidence
         compliance with Section 4(h).

                  (iii) The Company may offer securities of the Company other
         than the Notes under the Shelf Registration Statement, except where
         such offer would conflict with the terms of the Purchase Agreement.

thereof or supplement thereto, or arise out of, or are based upon, the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, judgment, liability or action; PROVIDED,
HOWEVER, that (i) the Company will not be liable in any case to the extent that
any such loss, claim, damage or liability arises out of, or is based upon, any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any such Holder
specifically for inclusion therein and (ii) the Company will not be liable to
any indemnified party under this indemnity agreement with respect to the Shelf
Registration Statement or Prospectus to the extent that any such loss, claim,
damage or liability of such indemnified party results solely from an untrue
statement of a material fact contained in, or the omission of a material fact
from, the Shelf Registration Statement or Prospectus, which untrue statement or
omission was corrected in an amended or supplemented Shelf Registration
Statement or Prospectus, if the person alleging such loss, claim, damage or
liability was not sent or given, at or prior to the written confirmation of such
sale, a copy of the amended or supplemented Shelf Registration Statement or
Prospectus if the Company had previously furnished copies thereof to such
indemnified party and if delivery of a prospectus is required by the Act and was
not so made. This indemnity agreement will be in addition to any liability which
the Company may otherwise have.

         (b) Each Holder of Transfer Restricted Securities covered by a Shelf
Registration Statement (including each Initial Purchaser) severally agrees to
indemnify and hold harmless (i) the Company, (ii) each of its directors, (iii)
each of its officers who signs such Shelf Registration Statement and (iv) each
person who controls the Company within the meaning of either the Act or the
Exchange Act to the same extent as the foregoing indemnity from the Company to
each such Holder, but only with reference to written information relating to
such Holder furnished to the Company by or on behalf of such Holder specifically
for inclusion in the documents referred to in the foregoing indemnity. This
indemnity agreement will be in addition to any liability which any such Holder
may otherwise have. In no event shall any Holder, its directors, officers or any
person who controls such Holder be liable or responsible for any amount in
excess of the amount by which the total amount received by such Holder with
respect to its sale of Transfer Restricted Securities pursuant to a Shelf
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages that such
Holder, its directors, officers or any person who controls such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

         (c) Promptly after receipt by an indemnified party under this Section 7
or notice of the commencement of any action, the indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 7, notify the indemnifying party in writing of the commencement thereof;
but the failure to so notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party


                                       11

<PAGE>

from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. The indemnifying party shall
be entitled to assume the defense of any such claim and to appoint counsel of
the indemnifying party's choice at the indemnifying party's expense to represent
the indemnified party in any action for which indemnification is sought (in
which case the indemnifying party shall not thereafter be responsible for the
fees and expenses of any separate counsel retained by the indemnified party or
parties except as set forth below); PROVIDED, HOWEVER, that such counsel shall
be reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel (and local
counsel) if (i) the use of counsel chosen by the indemnifying party to represent
the indemnified party would present such counsel with a conflict of interest,
(ii) the actual or potential defendants in, or targets of, any such action
include both the indemnified party and the indemnifying party, and the
indemnified party reasonably concluded that there may be legal defenses
available to it and/or other indemnified parties that are different from or
additional to those available to the indemnifying party, (iii) the indemnifying
party did not employ counsel satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of the institution
of such action or (iv) the indemnifying party authorized the indemnified party
to employ separate counsel at the expense of the indemnifying party. The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against all losses, claims, damages and liabilities by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and, prior to the date of such settlement, the indemnifying party shall
have failed to comply with such reimbursement request. Notwithstanding the
immediately preceding sentence, if at any time an indemnified party shall have
requested an indemnifying party to reimburse the indemnified party for fees and
expenses of counsel, an indemnifying party shall not be liable for any
settlement of the nature contemplated by the immediately preceding sentence
effected without its consent if such indemnifying party (i) reimburses such
indemnified party in accordance with such request to the extent that it
considers such request to be reasonable and (ii) provides written notice to the
indemnified party substantiating the unpaid balance as unreasonable, in each
case, prior to the date of settlement. An indemnifying party shall not, without
the prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding for which indemnification or contribution may
be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action), unless such settlement, compromise
or consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding and does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

         (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 7 is unavailable or insufficient to hold harmless an indemnified
party for any reason, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall to the extent


                                       12

<PAGE>

permitted by law have a joint and several obligation to contribute to the
aggregate losses, claims, damages and liabilities (including legal or other
expenses reasonably incurred in connection with investigating or defending same)
(collectively "LOSSES") to which such indemnified party may be subject in such
proportion as is appropriate to reflect the relative benefits received by such
indemnifying party, on the one hand, and such indemnified party, on the other
hand, from the Initial Placement and the Shelf Registration Statement that
resulted in such Losses; PROVIDED, HOWEVER, that in no case shall any Initial
Purchaser be responsible, in the aggregate, for any amount in excess of the
purchase discount or commission applicable to such Note, as set forth in Section
2 of the Purchase Agreement. If the allocation provided by the immediately
preceding sentence is unavailable for any reason, the indemnifying party and the
indemnified party shall contribute in such proportion as is appropriate to
reflect not only such relative benefits, but also the relative fault of such
indemnifying party, on the one hand, and such indemnified party, on the other
hand, in connection with the statements or omissions which resulted in such
Losses, as well as any other relevant equitable considerations. Benefits
received by the Company shall be deemed to be equal to the sum of (x) the total
net proceeds from the Initial Placement (before deducting expenses) as set forth
in Section 2 of the Purchase Agreement and (y) the total amount of additional
interest that the Company was not required to pay as a result of registering the
securities covered by the Shelf Registration Statement that resulted in such
Losses. Benefits received by the Initial Purchasers shall be deemed to be equal
to the total purchase discounts and commissions as set forth in Section 2 of the
Purchase Agreement, and benefits received by any other Holders shall be deemed
to be equal to the value of the Transfer Restricted Securities sold by such
Holders under the Shelf Registration Statement. Relative fault shall be
determined by reference to whether any alleged untrue statement or omission
relates to information provided by the indemnifying party, on the one hand, or
by the indemnified party, on the other hand. The parties agree that it would not
be just and equitable if contribution were determined by pro rata allocation or
any other method of allocation that does not take account of the equitable
considerations referred to above. Notwithstanding the provisions of this
paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was guilty of such fraudulent misrepresentation. For purposes of this
Section 7, each person who controls a Holder within the meaning of either the
Act or the Exchange Act and each director, officer, employee and agent of such
Holder shall have the same rights to contribution as such Holder, and each
person who controls the Company within the meaning of either the Act or the
Exchange Act, each officer of the Company who shall have signed the Shelf
Registration Statement and each director of the Company shall have the same
rights to contribution as the Company, subject in each case to the applicable
terms and conditions of this paragraph (d). The obligations of each Holder and
each Initial Purchaser hereunder are several and not joint.

         (e) The provisions of this Section 7 shall remain in full force and
effect, regardless of any investigation made by or on behalf of any Holder or
the Company or any of the officers, directors or controlling persons referred to
in Section 7 hereof, and will survive the sale by a Holder of Transfer
Restricted Securities or Exchange Notes.

SECTION 8 RULE 144A AND RULE 144

                                       13

<PAGE>


         The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 9 MISCELLANEOUS

         (a) NO INCONSISTENT AGREEMENTS. The Company has not, as of the date
hereof, entered into, nor shall it, on or after the date hereof, enter into, any
agreement with respect to its securities that would prevent the Company from
satisfying or continuing to satisfy its obligations herein or that would
otherwise conflict with the provisions hereof. Without limiting the foregoing,
the Company may from time to time grant registration rights to holders of its
securities so long as such rights do not diminish the contractual obligations of
the Company to the Holders herein.

         (b) AMENDMENTS AND WAIVERS. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, qualified, 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 the
Holders of at least a majority of the then outstanding aggregate principal
amount of Notes; PROVIDED, HOWEVER, that with respect to any matter that
directly or indirectly adversely affects the rights of any Initial Purchaser
hereunder, the Company shall obtain the written consent of each such Initial
Purchaser against which such amendment, qualification, supplement, waiver or
consent is to be effective. Notwithstanding the foregoing (except the foregoing
proviso), a waiver or consent to depart from the provisions hereof, with respect
to a matter, which relates exclusively to the rights of Holders whose securities
are being sold pursuant to a Shelf Registration Statement and does not directly
or indirectly adversely affect the rights of other Holders, may be given by the
Majority Holders, determined on the basis of Notes being sold rather than
registered under such Shelf Registration Statement.

         (c) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telex, telecopier, or air courier guaranteeing overnight delivery:

                  (i) if to a Holder, at the most current address given by such
         holder to the Company in accordance with the provisions of this Section
         9(c), which address initially is, with respect to each Holder, the
         address of such Holder maintained by the registrar under the Indenture

                  (ii) with a copy in like manner to Banc of America Securities
         LLC;


                                       14

<PAGE>

                  (iii) if to the Initial Purchasers, initially at the
         respective addresses set forth in the Purchase Agreement; and

                  (iv) if to the Company, initially at its address set forth in
         the Purchase Agreement.

         All such notices and communications shall be deemed to have been duly
given when received.

         Upon the date of filing of a Shelf Registration Statement notice shall
be delivered to Banc of America Securities LLC, on behalf of the Initial
Purchasers in the form attached hereto as Exhibit A.

         The Initial Purchasers or the Company by notice to the other may
designate additional or different addresses for subsequent notices or
communications.

         (d) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
of, and be binding upon, the successors and assigns of each of the parties
hereto, including, without the need for an express assignment or any consent by
the Company thereto, subsequent Holders of Notes. The Company hereby agrees to
extend the benefits of this Agreement to any Holder of Notes and any such Holder
may specifically enforce the provisions of this Agreement as if an original
party hereto.

         (e) 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 an original, and all of which taken
together shall constitute one and the same agreement.

         (f) HEADINGS. The headings in this agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (g) GOVERNING LAW. This agreement shall be governed by and construed in
accordance with the internal laws of the State of New York applicable to
agreements made and to be performed in said State (without reference to the
conflict of law rules thereof).

         (h) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and the
remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties
shall be enforceable to the fullest extent permitted by law.

         (i) NOTES HELD BY THE COMPANY, ETC. Whenever the consent or approval of
Holders of a specified percentage of principal amount of Notes is required
hereunder, Notes held by the Company or its Affiliates (other than subsequent
Holders of Notes if such subsequent Holders are deemed to be Affiliates solely
by reason of their holdings of such Notes) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.

         (j) ENTIRE AGREEMENT. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive

to the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein

Restricted Securities. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.
