for an offering to be made on a delayed or continuous basis pursuant to Rule 415

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 reasonable methods of distribution elected by the Holders,
reasonably approved by the Company, and set forth in the Initial Shelf
Registration Statement. The Company shall not permit any securities other than
the Registrable Securities to be included in any Shelf Registration Statement.
The Company shall use its reasonable best efforts to cause the Initial Shelf
Registration Statement to be declared effective under the Securities Act as
promptly as is practicable but in any event by the date (the "EFFECTIVENESS
DEADLINE DATE") that is 360 days after the Issue Date, and to keep the Initial
Shelf Registration Statement (or any Subsequent Shelf Registration Statement)
continuously effective under the Securities Act until the expiration of the

the Effectiveness Period, the

                                       4
<PAGE>

Company shall use its reasonable best efforts to obtain the prompt withdrawal of
any order suspending the effectiveness thereof, and in any event shall within 10
days of such cessation of effectiveness amend the Shelf Registration Statement
in a manner reasonably expected 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 its
reasonable best efforts to cause the Subsequent Shelf Registration Statement to
become effective as promptly as is practicable after such filing and to keep
such Shelf Registration Statement (or subsequent Shelf Registration Statement)
continuously effective until the end of the Effectiveness Period.

      (c) 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 as reasonably requested by the Purchasers
or Trustee on behalf of the Holders covered by such Shelf Registration
Statement.

      (d) Each Holder 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 wishing to sell Registrable Securities pursuant to a Shelf Registration
Statement and related Prospectus agrees to deliver a completed and executed
Notice and Questionnaire to the Company prior to any attempted or actual
distribution of Registrable Securities under the Shelf Registration Statement;
provided that (A) the Company shall send the Notice and Questionnaire to each
Holder as soon as practicable, but not later than 30 Business Days prior to the
Filing Deadline Date and (B) Holders shall have at least 20 Business Days from
the date on which the Notice and Questionnaire is first sent to such Holders by
the Company to complete and return the Notice and Questionnaire to the Company.
From and after the date the Initial Shelf Registration Statement is declared
effective, the Company shall, as promptly as practicable after the date a Notice
and Questionnaire is delivered, and in any event within the later of (x) five
Business Days after such date or (y) five Business Days after the expiration of
any Suspension Period (1) in effect when the Notice and Questionnaire is
delivered or (2) put into effect within five Business Days of such delivery
date, (i) if required by applicable law, file with the SEC a post-effective
amendment to the Shelf Registration Statement or, if required by applicable law,
prepare and file a supplement to the related Prospectus or a supplement or
amendment to any document incorporated therein by reference or file any other
required document 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 its reasonable best efforts to cause such
post-effective amendment to be declared effective under the Securities Act as
promptly as is practicable, but in any event by the date (the "AMENDMENT
EFFECTIVENESS DEADLINE DATE") that is 45 days after the date such post-effective
amendment is required by this clause to be filed; (ii) provide such Holder a
reasonable number of copies of any documents filed pursuant to Section 2(d)(i);
and (iii) notify such Holder as promptly as 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 Suspension Period,

                                       5
<PAGE>

or a Suspension Period is put into effect within five Business Days after such
delivery date, 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 within ten Business Days after expiration of the Suspension Period
in accordance with Section 3(i). 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 Shelf Registration
Statement or related Prospectus; provided, however, that any Holder that becomes
a Notice Holder pursuant to the provisions of this Section 2(d) (whether or not
such Holder was a Notice Holder at the time the Shelf Registration Statement was
declared effective) shall be named as a selling securityholder in the Shelf
Registration Statement or related Prospectus in accordance with the requirements
of this Section 2(d).

      (e) 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
Initial Shelf Registration Statement is filed and declared effective but shall
thereafter cease to be effective (without being succeeded immediately by an
additional registration statement filed and declared effective) or usable for
the offer and sale of Registrable Securities for a period of time (including any
Suspension Period) which shall exceed 45 days in the aggregate in any
three-month period or 90 days in the aggregate in any 12-month period (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), the date on which the duration of the ineffectiveness or unusability of
the Initial Shelf Registration Statement in any period exceeds the number of
days permitted by clause (iii) hereof in the case of clause (iii), being
referred to herein as an "EVENT DATE"). Events shall be deemed to continue until
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), and the date the Initial Shelf Registration
Statement becomes effective or usable again in the case 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 "LIQUIDATED DAMAGES ACCRUAL PERIOD"), the Company and the
Guarantors severally agree to pay, as liquidated damages and not as a penalty,
("LIQUIDATED DAMAGES") at the rate described below, payable periodically on each
Liquidated Damages Payment Date to Record Holders of Notes that are Registrable
Securities and of shares of Underlying Common Stock issued upon conversion of
Notes that are Registrable Securities, as the case may be, to the extent of, for
each such Liquidated Damages Payment Date, accrued and unpaid Liquidated Damages
to (but excluding) such Liquidated Damages Payment Date (or, if the Liquidated
Damages Accrual Period shall have ended prior to such Liquidated Damages Payment
Date, to the date of the end of the Liquidated Damages Accrual Period); provided
that any Liquidated Damages accrued with respect to any Note or portion thereof
called for redemption on a redemption date or converted into Underlying Common
Stock on a conversion date prior to the Liquidated Damages Payment

                                       6
<PAGE>

Date, shall, in any such event, be paid instead to the Holder who submitted such
Note 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). Liquidated
Damages shall accrue at a rate per annum equal to (1) 0.25% for the first 90-day
period from the Event Date and (2) 0.50% thereafter of (i) the aggregate
principal amount of such Notes or, without duplication, (ii) in the case of
Notes that have been converted into Underlying Common Stock, the Applicable
Conversion Price of such shares of Underlying Common Stock, as the case may be,
in each case determined as of the Business Day immediately preceding the next
Liquidated Damages Payment Date. Notwithstanding the foregoing, no Liquidated
Damages 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 Liquidated
Damages 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 or any
Guarantor of Liquidated Damages to the Holders of Registrable Securities
pursuant to this Section, the accrual of Liquidated Damages shall cease (without
in any way limiting the effect of any subsequent Event requiring the payment of
Liquidated Damages by the Company or any Guarantor).

      The Trustee shall be entitled, on behalf of Holders of Notes, to seek any
available remedy for the enforcement of this Agreement, including for the
payment of any Liquidated Damages. Notwithstanding the foregoing, the parties
agree that the sole monetary damages payable for a violation of the terms of
this Agreement with respect to which liquidated damages are expressly provided
shall be such liquidated damages. Nothing shall preclude a Holder from pursuing
or obtaining a specific performance or equitable relief with respect to this
Agreement.

      All of the Company's and each Guarantor'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(k)).

      The parties hereto agree that the liquidated damages provided for in this
Section 2(e) constitutes 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.

      Section 3. Registration Procedures. In connection with the registration
obligations of the Company under Section 2 hereof, the Company shall:

      (a) Prepare and file with the SEC a Shelf Registration Statement or Shelf
Registration Statements on Form S-3 or any other appropriate form under the
Securities Act available for the sale of the Registrable Securities by the

Shelf Registration Statement to become effective and remain effective as
provided herein; provided that before filing any Shelf Registration Statement or
Prospectus or any amendments or

<PAGE>

supplements thereto with the SEC, the Company shall furnish to the Holders and
counsel for the Holders copies of all such documents proposed to be filed which
documents (other than a prospectus supplement filed solely to update the selling
stockholder information in the Prospectus) will be subject to the review of such
counsel for a period of no less than ten Business Days prior to the initial
filing of the Shelf Registration Statement or any post-effective amendment
thereto or no less than three Business Days prior to the filing of a
pre-effective amendment to the Shelf Registration Statement, and the Company
will not file the Shelf Registration Statement or Prospectus or any amendment or
supplement thereto (other than documents incorporated by reference) to which
such counsel shall reasonably object within three Business Days after the
receipt thereof.

      (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration Statement as may be necessary to keep such
Shelf Registration Statement continuously effective until the expiration of the
Effectiveness Period; 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 its reasonable best efforts to comply with the provisions of the Securities
Act applicable to it with respect to the disposition of all securities covered
by such Shelf Registration Statement during the Effectiveness Period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such Shelf Registration Statement as so amended or such Prospectus as
so supplemented.

      (c) As promptly as practicable give notice to the Notice Holders, the
Purchasers and counsel to the Holders (i) when any Prospectus, Prospectus
supplement, Shelf Registration Statement or post-effective amendment to a Shelf
Registration Statement has been filed with the SEC and, with respect to a Shelf
Registration Statement or any post-effective amendment, when the same has been
declared effective, (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 Shelf 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
Shelf 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) after the
effective date of any Shelf Registration Statement filed pursuant to this
Agreement of the occurrence of (but not the nature of or details concerning) a
Material Event and (vi) of the determination by the Company that a
post-effective amendment to a Shelf 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 Suspension Notice, in
which event the provisions of Section 3(i) shall apply.

      (d) Use its reasonable best efforts to prevent the issuance of, and, if
issued, to obtain the withdrawal of any order suspending the effectiveness of a
Shelf 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

                                       8
<PAGE>

either case at the earliest possible moment, and provide prompt notice to each
Notice Holder and the Purchasers of the withdrawal of any such order.

      (e) If requested by the Purchasers or any Notice Holder, as promptly as
practicable incorporate in a Prospectus supplement or post-effective amendment
to a Shelf Registration Statement such information as the Purchasers or such
Notice Holder shall, on advice from counsel, 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,
on advice from counsel for the Company, the Company determines would not be in
compliance with applicable law.

      (f) As promptly as practicable furnish to each Notice Holder, counsel for
the Holders and for the Purchasers, without charge, at least one conformed copy
of the Shelf 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, which
obligation shall be deemed satisfied if such information is available through
EDGAR or on or through the Company's website.

      (g) During the Effectiveness Period, deliver to each Notice Holder, the
Purchasers and counsel for the Holders, in connection with any sale of
Registrable Securities pursuant to a Shelf 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 and the Purchasers may reasonably
request; and the Company hereby consents (except during such periods that a
Suspension 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.

      (h) Prior to any public offering of the Registrable Securities pursuant to
the Shelf Registration Statement, use its reasonable best 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); and prior to any public offering of the Registrable Securities
pursuant to the Shelf Registration Statement, use its reasonable best 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
reasonably necessary or advisable to enable the disposition in such
jurisdictions of such Registrable Securities in the manner set forth in the
relevant Shelf 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 would not otherwise be
required to qualify 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.

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

not to sell any Registrable Securities pursuant to such Shelf Registration
Statement until such Notice Holder's receipt of copies of the supplemented or
amended Prospectus provided for in clause (g) 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 its
reasonable best efforts to ensure that the use of the Prospectus may be resumed
(x) in the case of clause (A) above, as promptly as is practicable, (y) in the
case of clause (B) above, as soon as, in the reasonable judgment of the Company,
the Shelf Registration Statement does not contain any untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading and the Prospectus
does not contain any untrue statement of a material fact or omits to state any
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, and (z) in the
case of clause (C) above, as soon as, in the reasonable discretion of the
Company, such suspension is no longer appropriate. The period during which the
availability of the Shelf Registration Statement and any Prospectus may be
suspended (the "SUSPENSION PERIOD") without the Company incurring any obligation
to pay liquidated damages pursuant to Section 2(e) shall not exceed 30 days in
any three-month period and 90 days in any 12-month period; provided, however,
that if the use

                                       10
<PAGE>

of the Shelf Registration Statement or any Prospectus is suspended by the
Company pursuant to clause (C) above and the subject Material Event relates to a
previously undisclosed proposed or pending material business transaction, the
disclosure of which would impede the Company's ability to consummate such
transaction or cause the Company to violate any non-disclosure agreement or
confidentiality agreement in any contract relating to such transaction, the
Company may extend a Suspension Period from 30 days to 45 days.

      (j) Make available for inspection during normal business hours by
representatives for the Notice Holders of such Registrable Securities, and any
investment banks, attorneys and accountants retained by such Notice Holders, all
relevant financial and other records and pertinent corporate documents and
properties of the Company and its subsidiaries, and cause the appropriate
officers, directors and employees of the Company and its subsidiaries to make
available for inspection during normal business hours all relevant information
reasonably requested by such representatives for the Notice Holders, or any such
investment banks, 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, at the Company's request, first agree in
writing with the Company that any information that is reasonably and in good
faith 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,
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 Shelf 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 or is not otherwise under a duty of trust to the Company, and provided
that the foregoing inspection and information gathering shall, to the greatest
extent possible, be coordinated on behalf of all the Notice Holders.

      (k) Cooperate with each Notice Holder to facilitate the timely preparation
and delivery of certificates representing Registrable Securities sold pursuant
to a Shelf Registration Statement, which certificates shall not bear any
restrictive legends, and cause such Registrable Securities to be registered in
such names as such Notice Holder may request in writing at least three Business
Days prior to any sale of such Registrable Securities.

      (l) Provide the Trustee 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.

      (m) 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 45 days after the end of any 12-month period (or 90 days after the
end of any 12-month period if such period is a fiscal year) commencing on

                                       11
<PAGE>

the first day of the first fiscal quarter of the Company commencing after the
effective date of a Registration Statement, which statements shall cover said
12-month periods.

      (n) Upon (i) the filing of the Initial Registration Statement and (ii) the
effectiveness of the Initial Registration Statement, announce the same, in each
case by press release to a nationally recognized wire service.

      (o) 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 and the transfer agent for the Common Stock
with printed certificates for the Registrable Securities that are in a form
eligible for deposit with The Depository Trust Company.

      (p) Cause all shares of Common Stock issuable upon conversion of the
Securities to be reserved for listing on each securities exchange or quotation
system on which the Common Stock is then listed no later than the date the
applicable Shelf Registration Statement is declared effective and, shall cause
all Common Stock to be so listed when issued.

      (q) Use its reasonable best efforts to take all other steps necessary to
effect the registration of the Registrable Securities covered by the Shelf
Registration Statement contemplated hereby.

      (r) Enter into such customary agreements and take all such other necessary
actions in connection therewith (including those requested by the holders of a
majority of the Registrable Securities being sold) in order to expedite or
facilitate the disposition of such Registrable Securities.

      (s) If the Registrable Securities are in certificated form, cooperate with
the Holders to facilitate the timely preparation and delivery of certificates
representing the Registrable Securities sold pursuant to any Shelf Registration
Statement free of any restrictive legends and, with respect to any Notes, in
such denominations permitted by the Indenture and registered in such names as
Holders may request at least two Business days prior to settlement of sales of
Registrable Securities pursuant to such Shelf Registration Statement.

      (t) Subject to the exceptions contained in clauses (i) and (ii) of Section
3(h) above, use its reasonable best efforts to cause the Registrable Securities
covered by the applicable Shelf Registration Statement to be registered with or
approved by such other federal, state and local governmental agencies or
authorities, and self-regulatory organizations in the United States as may be
necessary to enable the Holders to consummate the disposition of such
Registrable Securities as contemplated by the Shelf Registration Statement.

      Section 4. Holder's Obligations. Each Holder agrees, by acquisition of the
Registrable Securities, that no Holder shall be entitled to sell any of such
Registrable Securities pursuant to a Shelf 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

                                       12
<PAGE>

other information regarding such Notice Holder and the distribution of such
Registrable Securities as the Company may from time to time reasonably request.
Any sale of any Registrable Securities by any Holder shall constitute a
representation and warranty by such Holder that the information relating to such
Holder and its plan of distribution is as set forth in the Prospectus delivered
by such Holder in connection with such disposition, that such Prospectus does
not as of the time of such sale contain any untrue statement of a material fact
relating to or provided by such Holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact
relating to or provided by such Holder or its plan of distribution necessary in
order to make the statements in such Prospectus, in the light of the
circumstances under which they were made, not misleading.

      Section 5. Registration Expenses. The Company shall bear all fees and
expenses incurred in connection with the performance by the Company of its
obligations under Section 2 and 3 of this Agreement whether or not any of the
Shelf Registration Statements are declared effective. Such fees and expenses
("REGISTRATION 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 New York Stock
Exchange, and (y) of compliance with federal and state securities or Blue Sky
laws, (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 and mailing expenses
relating to copies of any Shelf Registration Statement or Prospectus delivered
to any Holders hereunder, (iv) fees and disbursements of counsel for the Company
and the fees and disbursements of one counsel chosen by the Holders of a
majority of the then outstanding Underlying Common Stock constituting
Registrable Securities (with Holders of Notes deemed to be the Holders, for
purposes of this Section, of the number of outstanding shares of Underlying
Common Stock into which such Notes are or would be convertible, not including,
for this purpose only, any shares of Common Stock payable as a Make-Whole
Premium (as defined in the Indenture) upon conversion of any Note) in connection
with the Shelf Registration Statement, and (v) 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 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 by the
Company of the Registrable Securities on any securities exchange on which
similar securities of the Company are then listed and the fees and expenses of
any person, including special experts, retained by the Company.

      Section 6. Indemnification; Contribution.

      (a) The Company and the Guarantors severally agree to indemnify and hold
harmless each Holder and its directors, officers, employees, members,
representatives and agents and each person, if any, who controls any Holder
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act (each, a "HOLDER INDEMNIFIED PARTY"), from and against (i) any
loss, damage, expense, liability or claim (including the reasonable cost of
investigation) which such Holder Indemnified Party may incur under the
Securities Act, the Exchange Act or otherwise, as incurred, insofar as such
loss, damage, expense, liability or claim arises out of or is based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Shelf Registration Statement or Prospectus or in any amendment or supplement
thereto or in any

                                       13
<PAGE>

preliminary prospectus, or arises out of or is based upon any omission or
alleged omission to state a material fact required to be stated in any Shelf
Registration Statement or in any amendment or supplement thereto or necessary to
make the statements therein not misleading, or arises out of or is based upon
any omission or alleged omission to state a material fact necessary in order to
make the statements made in any Prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, in the light of the circumstances
under which they were made, not misleading, except insofar as any such loss,
damage, expense, liability or claim arises out of or is based upon any untrue
statement or omission or alleged untrue statement or omission of a material fact
contained in, or omitted from, and in conformity with information required to be
included in any Shelf Registration Statement or the related Prospectus pursuant
the Securities Act furnished in writing by or on behalf of any Holder to the
Company, (ii) 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 any such settlement is effected with the written consent of the
Company; and (iii) any and all expense whatsoever, as incurred (including the
fees and disbursements of counsel chosen by any indemnified party), 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 subparagraph (i) or (ii) above; provided,
however, that as to any preliminary prospectus, this indemnity agreement shall
not inure to the benefit of any Holder Indemnified Party on account of any loss,
claim, damage, liability or action arising from the sale of the Registrable
Securities sold pursuant to the Shelf Registration Statement to any person by
such Holder Indemnified Party if (i) that Holder Indemnified Party failed to
send or give a copy of the Prospectus, as the same may be amended or
supplemented, to that person within the time required by the Securities Act
(other than as a result of a failure by the Company to timely deliver copies of
the Prospectus to such Holder Indemnified Party) and (ii) the untrue statement
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact in such preliminary prospectus was corrected in the
Prospectus or a supplement or amendment thereto, as the case may be. This
indemnity agreement will be in addition to any liability that the Company or any
Guarantor may otherwise have.

      (b) Each Holder, severally and not jointly, agrees to indemnify, defend
and hold harmless the Company and the Guarantors, and their directors, officers,
employees, members, representatives and agents and each person, if any, who
controls the Company or any Guarantor within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act (each, a "COMPANY
INDEMNIFIED PARTY") from and against any loss, damage, expense, liability or
claim (including the reasonable cost of investigation) which such Company
Indemnified Party may incur under the Securities Act, the Exchange Act or
otherwise, insofar as such loss, damage, expense, liability or claim arises out
of or is based upon any untrue statement or alleged untrue statement of a
material fact contained in information furnished in writing by or on behalf of
such Holder to the Company required to be included in any Shelf Registration
Statement or the related Prospectus pursuant the Securities Act, or arises out
of or is based upon any omission or alleged omission to state a material fact
required to be stated in any Shelf Registration Statement or in any amendment or
supplement thereto or necessary to make the statements therein not

                                       14
<PAGE>

misleading, or arises out of or is based upon any omission or alleged omission
to state a material fact necessary in order to make the statements in any
Prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, in the light of the circumstances under which they were made, not
misleading, in connection with such information; provided, however, that no such
Holder shall be liable for any claims hereunder in excess of the amount of net
proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Shelf Registration Statement.

      (c) If any action, suit or proceeding (each, a "PROCEEDING") is brought
against any person in respect of which indemnity may be sought pursuant to
either subsection (a) or (b) of this Section 6, such person (the "INDEMNIFIED
PARTY") shall promptly notify the person against whom such indemnity may be
sought (the "INDEMNIFYING PARTY") in writing of the institution of such
Proceeding and the Indemnifying Party shall assume the defense of such
Proceeding with counsel reasonably satisfactory to the Indemnified Party and
shall pay the fees and expenses of such counsel; provided, however, that failure
to so notify the 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 otherwise have than on account of this indemnity agreement. Such Indemnified
Party shall have the right to employ its own counsel, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnified Party is a Holder of Notes representing not less than 33% of the
aggregate principal amount of the then outstanding Notes, (ii) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the contrary,
(iii) the Indemnifying Party has failed within a reasonable time after receipt
of notice to assume defense of a Proceeding to retain counsel reasonably
satisfactory to the Indemnified Party or (iv) the named parties in any such
Proceeding (including any impleaded parties) include both the Indemnifying Party
and the Indemnified Party, the Indemnifying Party proposes to have the same
counsel represent it 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
may, in connection with any Proceeding or related Proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Parties in accordance
with the foregoing sentence, and that all such fees and expenses actually
incurred shall be promptly reimbursed as incurred upon delivery to the
Indemnifying Party of reasonable documentation therefor setting forth such
expenses in reasonable detail. 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 judgment for the plaintiff, the
Indemnifying Party agrees to indemnify and hold harmless any Indemnified Party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an Indemnified Party
shall have requested the Indemnifying Party to reimburse the Indemnified Party
as contemplated by this paragraph, the Indemnifying Party agrees that it shall
be liable for any settlement of any Proceeding effected without its consent if
(i) such settlement is entered into more than 60 Business Days after receipt by
the Indemnifying Party of the aforesaid request, (ii) such indemnifying party
shall not have reimbursed the Indemnified Party in accordance with such request
prior to the date of such settlement and (iii) such Indemnified Party shall have
given such Indemnifying Party at least 30 days' prior notice of its intention to
settle. No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending or threatened Proceeding
in respect of which any Indemnified Party is a party,

                                       15
<PAGE>

unless such settlement includes an unconditional release of such Indemnified
Party from all liability on claims that are the subject matter of such
Proceeding and without admission of fault by the Indemnified Party.

      (d) If the indemnification provided for in this Section 6 is unavailable
to an Indemnified Party under subsections (a) and (b) of this Section 6 in
respect of any losses, damages, expenses, liabilities or claims referred to
therein, then each applicable Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, damages, expenses, liabilities or
claims, as incurred, (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Holders on the
other hand from the offering of the Registrable Securities or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and of the Holders on the other in connection with the statements
or omissions which resulted in such losses, damages, expenses, liabilities or
claims, as well as any other relevant equitable considerations. Notwithstanding
the provisions of this Section 6, neither any of the Purchasers nor any Holder
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
or Purchaser, as the case may be, exceeds the amount of any damages that such
Holder or Purchaser has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. The relative fault
of the Company on the one hand and of the Holders on the other shall be
determined by reference to, among other things, whether the untrue statement or
alleged untrue statement of a material fact or omission or alleged omission
relates to information supplied by the Company or by the Holders and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The amount paid or payable by a
party as a result of the losses, damages, expenses, liabilities and claims
referred to above shall be deemed to include any reasonable legal or other fees
or expenses reasonably incurred by such party in connection with investigating
or defending any Proceeding.

      (e) The Company, the Guarantors and the Holders agree that it would not be
just and equitable if contribution pursuant to this Section 6 were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in subsection (d) above. 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. The Holders' respective
obligations to contribute pursuant to this Section 6 are several in proportion
to the respective amount of Registrable Securities they have sold pursuant to a
Shelf Registration Statement, and not joint. The remedies provided for in this
Section 6 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.

      (f) The indemnity and contribution provisions contained in this Section 6
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Holder or any person controlling any Holder, or the Company or Guarantors,
or the Company's or any Guarantor's officers or directors or any

                                       16
<PAGE>

person controlling the Company or any Guarantor and (iii) the sale of any
Registrable Security by any Holder.

      (g) Section 6 of this Agreement may not be amended except by an instrument
in writing signed by the Indemnified Party affected hereto.

      Section 7. Information Requirements.

      (a) The Company covenants that, if at any time before the end of the
Effectiveness Period it is not subject to the reporting requirements of the
Exchange Act, it will cooperate with any Holder and take such further action as
any Holder may reasonably request in writing, 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, Rule 144A, Regulation S and Regulation D under the
Securities Act and customarily taken in connection with sales pursuant to such
exemptions. Upon the written request of any Holder, the Company shall deliver to
such Holder a written statement as to whether it has complied with such filing
requirements, unless such a statement has been included in the Company's most
recent report filed with the SEC 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 (other than the
Common Stock) under any section of the Exchange Act.

      (b) The Company shall file the reports required to be filed by it under
the Exchange Act and shall comply with all other requirements set forth in the
instructions to Form S-1 or Form S-3, as the case may be, in order to allow the
Company to be eligible to file registration statements on Form S-1 or Form S-3.

      Section 8. Miscellaneous.

      (a) No Contrary Agreements. The Company is not, as of the date hereof, a
party to, nor shall it, on or after the date of this Agreement, enter into, any
agreement with respect to its securities that violates 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 violate the rights granted to the holders of such
Company's securities under any other agreements. Notwithstanding the foregoing,
the Holders acknowledge that the Company is obligated, and may obligate itself
from time to time in the future, to register its securities for other holders.

      (b) Amendments and Waivers. Except as otherwise provided in Section 6(g),
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 Notes deemed
to be the Holders, for purposes of this Section, of the number of outstanding
shares of Underlying Common Stock into which such Notes are or would be
convertible as of the date on which such consent is requested excluding, for
this purpose only, any shares of Common Stock payable as a Make-Whole Premium
(as defined in the Indenture)

                                       17
<PAGE>

upon conversion of any Note). 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 Shelf 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 Shelf 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 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(b), 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.

      (c) 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,

required percentage.

      (e) Successors and Assigns. Any person who purchases any Notes or
Registrable Securities from the Purchasers or any Holder shall be deemed, for

by this Agreement.

      (f) Counterparts. This Agreement may be executed in any number of

The undersigned beneficial owner of Series A 6.5% Senior Convertible Notes due
2014 (the "NOTES") of the Company or common stock of the Company, $0.01 par
value (the "common stock" or the "REGISTRABLE SECURITIES"), understands that the
Registrant has filed or intends to file with the Securities and Exchange
Commission a registration statement on Form S-1 or Form S-3 (the "SHELF
REGISTRATION STATEMENT") for the registration and resale under Rule 415 of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), of the Registrable

defined herein shall have the meaning ascribed thereto in the Registration
Rights Agreement.

Each beneficial owner of Registrable Securities is entitled to the benefits of
the Registration Rights Agreement. In order to sell or otherwise dispose of any
Registrable Securities pursuant to the Shelf Registration Statement, a
beneficial owner of Registrable Securities generally will be required to be
named as a selling securityholder in the related prospectus, deliver a
