                     5.50% Convertible Senior Notes due 2026

                          REGISTRATION RIGHTS AGREEMENT

                                                               November 21, 2006

To the Purchasers Party to
The Purchase Agreement dated
November 15, 2006 with
C&D Technologies, Inc.

Dear Sirs:

            C&D Technologies, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell to the purchasers listed on Schedule I attached
hereto (collectively, the "Purchasers"), upon the terms set forth in a purchase
agreement dated November 15, 2006 (the "Purchase Agreement"), $54,500,000
aggregate principal amount of its 5.50% Convertible Senior Notes Due 2026 (the
"Notes"). The Notes will be convertible into shares of common stock, par value
$0.01 per share, of the Company (the "Common Stock") at the conversion rate set
forth in the Indenture, dated as of the date hereof (the "Indenture"), between
the Company and The Bank of New York, as trustee (the "Trustee"), and the Notes
will be issued pursuant to the Indenture. As an inducement to the Purchasers to
enter into the Purchase Agreement, the Company agrees with the Purchasers, for
the benefit of (i) the Purchasers and (ii) the holders of the Notes and the
Common Stock issuable upon conversion of the Notes (collectively, the
"Securities") from time to time until the earlier of (i) such time as such
Securities have been sold pursuant to a Shelf Registration Statement (as defined
below) or (ii) the expiration of the Shelf Registration Period (as defined
below) (each of the foregoing a "Holder" and collectively the "Holders"), as
follows:

            1. Shelf Registration.

            (a) The Company shall, at its cost, prepare and, as promptly as
practicable (but in no event more than ninety (90) days after the original
issuance of the Notes (such original issuance date, the "Closing Date")) file
with the Securities and Exchange Commission (the "Commission"), and thereafter
use its commercially reasonable efforts to cause to be declared effective, no
later than one hundred eighty (180) days after the Closing Date, a registration
statement (the "Shelf Registration Statement") on an appropriate form under the
Securities Act of 1933, as amended (the "Securities Act") relating to the offer
and sale of the Transfer

<PAGE>

Restricted Securities (as defined in Section 5(d) hereof) by the Holders thereof
from time to time in accordance with the methods of distribution set forth in
the Shelf Registration Statement and Rule 415 under the Securities Act
(hereinafter, the "Shelf Registration"); provided, however, that no Holder
(other than a Purchaser) shall be entitled to have the Securities held by it
covered by such Shelf Registration Statement unless such Holder agrees in
writing to be bound by all the provisions of this Agreement applicable to such
Holder.

            (b) The Company shall use its commercially reasonable efforts to
keep the Shelf Registration Statement continuously effective in order to permit
the prospectus included therein (the "Prospectus") to be lawfully delivered by
the Holders of the relevant Securities, for a period of two years (or for such
longer period if extended pursuant to Section 2(h) below) from the Closing Date
or such shorter period that will terminate when all the Securities covered by
the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) may
be sold pursuant to Rule 144(k) under the Securities Act, or any successor rule
thereof, or otherwise transferred in a manner that results in (A) the Securities
not being subject to transfer restrictions under the Securities Act and (B) the
absence of a need for a restrictive legend regarding registration under the
Securities Act (assuming for purpose of this Section 1(b)(ii) that the Holders
thereof are not affiliates of the Company) or (iii) cease to be outstanding (in
any such case, such period being called the "Shelf Registration Period"). The
Company shall be deemed not to have used its commercially reasonable efforts to
keep the Shelf Registration Statement effective during the requisite period if
it voluntarily takes any action that would result in Holders of Securities
covered thereby not being able to offer and sell such Securities during that
period, unless such action is (i) required by applicable law or (ii) taken by
the Company in good faith and contemplated by Section 2(b)(v) and 2(b)(vi)
below, and the Company thereafter complies with the requirements of Section
2(h).

            (c) Notwithstanding any other provisions of this Agreement to the
contrary, the Company shall cause the Shelf Registration Statement and the
Prospectus and any amendment or supplement thereto, as of the effective date of
the Shelf Registration Statement, amendment or supplement, (i) to comply in all
material respects with the applicable requirements of the Securities Act and the
rules and regulations of the Commission and (ii) not to contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading other than any such
statement that may be made or omitted in reasonable reliance upon and in
conformity with written information furnished by a Holder specifically for
inclusion therein.

            (d) Each Holder of Transfer Restricted Securities (as defined in
Section 5(d) hereof) agrees that if such Holder wishes to sell Transfer
Restricted Securities pursuant to the Shelf Registration Statement and related
Prospectus, it will do so only in accordance with this Section 1(d) and Section
2(h). Each Holder of Transfer Restricted Securities wishing to sell Transfer
Restricted Securities pursuant to the Shelf Registration Statement and related
Prospectus and to be listed as a selling securityholder in the Shelf
Registration Statement and related Prospectus at the time the Shelf Registration
Statement is declared effective (the "Effective Time") agrees to deliver a
written notice, substantially in the form of Annex A attached hereto (such a
notice, when completed, duly executed and so delivered, a "Notice and
Questionnaire") to the Company at least one (1) Business Day (a "Business Day"
meaning each

                                      - 2 -
<PAGE>

day that is not a Saturday, Sunday or legal holiday) prior to the filing of the
Shelf Registration Statement or any amendment thereto (each Holder delivering
the Notice and Questionnaire, a "Notice Holder"). From and after the date the
Shelf Registration Statement is declared effective, each Holder wishing to sell
Securities pursuant to the Shelf Registration Statement and related Prospectus
that has not previously delivered a Notice and Questionnaire to the Company in
accordance with the foregoing provisons of this Section 1(d) agrees to deliver a
Notice and Questionnaire to the Company at least five (5) Business Days prior to
any intended distribution of Transfer Restricted Securities under the Shelf
Registration Statement. The Company shall, as promptly as reasonably practicable
after the later of the date of receipt of a Notice and Questionnaire or the
expiration of any Suspension Period (as defined in Section 2(b) hereof) in
effect when the Notice and Questionnaire is delivered (i) if required by
applicable law, file with the Commission 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
under the Securities Act 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 Transfer Restricted Securities
in accordance with applicable law and, if the Company shall file a
post-effective amendment to the Shelf Registration Statement, use commercially
reasonable efforts to cause such post-effective amendment to be declared
effective under the Securities Act as promptly as is practicable; (ii) provide
such Holder copies of any documents filed pursuant to Section 1(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
1(d)(i).

            2. Registration Procedures. In connection with the Shelf
Registration contemplated by Section 1 hereof, the following provisions shall
apply:

            (a) The Company shall (i) give notice to the Holders in the manner
as set forth in the Indenture (A) of its intention to file a Shelf Registration
Statement (the "Filing Notice") and (B) when the Shelf Registration Statement or
any amendment thereto has been filed with the Commission and when the Shelf
Registration Statement or any post-effective amendment thereto has become
effective; and (ii) include the names of the Holders who propose to sell
Securities pursuant to the Shelf Registration Statement as selling
securityholders. The Filing Notice will seek, among other things, a
determination from each such Holder as to whether such Holder elects to have its
Notes and the Common Stock issuable on conversion thereof registered for sale
pursuant to the Shelf Registration Statement.

            (b) The Company shall give written notice (a "Deferral Notice") to
the Holders (which notice pursuant to clauses (ii)-(vi) hereof (each a "Material
Event") shall be accompanied by an instruction to suspend the use of the
Prospectus until the requisite changes have been made) of any of the following:

                  (i) when the Shelf Registration Statement or any amendment
thereto has been filed with the Commission and when the Shelf Registration
Statement or any post-effective amendment thereto has become effective;

                                      - 3 -
<PAGE>

                  (ii) any request by the Commission for amendments or
supplements to the Shelf Registration Statement or the Prospectus included
therein or for additional information, or it shall become necessary to amend
such Shelf Registration Statement or supplement the related prospectus to comply
with the Securities Act or the Securities Exchange Act of 1934, as amended (the
"Exchange Act") or the respective rules thereunder;

                  (iii) the issuance by the Commission of any stop order
suspending the effectiveness of the Shelf Registration Statement or the
initiation of any proceedings for that purpose;

                  (iv) the receipt by the Company or its legal counsel of any
notification with respect to the suspension of the qualification of the
Securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose;

                  (v) the happening of any event that requires the Company to
make changes in the Shelf Registration Statement or the Prospectus in order that
the Shelf Registration Statement or the Prospectus neither contains an untrue
statement of a material fact nor omits to state a material fact required to be
stated therein or necessary to make the statements therein (in the case of the
Prospectus, in light of the circumstances under which they were made) not
misleading; and

                  (vi) the occurrence or existence of any pending corporate
development or other similar event with respect to the Company or a public
filing with the Commission that, in the reasonable discretion of the Company,
makes it appropriate to defer the filing of the Shelf Registration Statement or
suspend the availability of a Shelf Registration Statement and the related
Prospectus.

The Company shall be entitled to exercise its right under this Section 2(b) to
defer the filing of or suspend the availability of the Shelf Registration
Statement and any Prospectus upon the occurrence of any event contemplated by
clauses (ii) through (vi) above, without incurring or accruing any obligation to
pay Additional Interest pursuant to Section 5, for one or more periods not to
exceed an aggregate of 30 days in any 3-month period or an aggregate of 60 days
in any 12-month period (such period during which the availability of the
Registration Statement and any Prospectus is suspended being a "Suspension
Period").

            (c) The Company shall use its commercially reasonable efforts to
obtain the withdrawal at the earliest possible time, of any order suspending the
effectiveness of the Shelf Registration Statement.

            (d) The Company shall furnish to each Holder of Securities included
within the coverage of the Shelf Registration Statement, without charge, at
least one copy of the Shelf Registration Statement and any post-effective
amendment thereto, including financial statements and schedules, and, if the
Holder so requests in writing, all exhibits thereto (including those, if any,
incorporated by reference); provided that the Company shall have no obligation
to furnish to any such Holder any document that is available on the Commission's
EDGAR system.

            (e) The Company shall, during the Shelf Registration Period, deliver
to each Holder of Securities included within the coverage of the Shelf
Registration Statement, without

                                      - 4 -
<PAGE>

charge, as many copies of the Prospectus (including each preliminary prospectus)
included in the Shelf Registration Statement and any amendment or supplement
thereto as such person may reasonably request. The Company consents, subject to
the provisions of this Agreement, to the use of the Prospectus or any amendment
or supplement thereto by each of the Notice Holders in connection with the
offering and sale of the Securities covered by the Prospectus, or any amendment
or supplement thereto, included in the Shelf Registration Statement.

            (f) Prior to any public offering of the Securities pursuant to the
Shelf Registration Statement, the Company shall use its commercially reasonable
efforts to register or qualify or cooperate with the Notice Holders included
therein and their respective counsel in connection with the registration or
qualification of the Securities for offer and sale under the securities or "blue
sky" laws of such states of the United States as any Notice Holder reasonably
requests in writing and do any and all other acts or things necessary or
advisable to enable the disposition in such jurisdictions of the Securities
covered by such Registration Statement; provided, however, that the Company
shall not be required to (i) qualify generally to do business in any
jurisdiction where it is not then so qualified or (ii) take any action which
would subject it to general service of process or to taxation in any
jurisdiction where it is not then so subject.

            (g) Subject to the terms of the Indenture, the Company shall
cooperate with the Notice Holders to facilitate the timely preparation and
delivery of certificates representing the Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations
and registered in such names as the Holders may request a reasonable period of
time prior to sales of the Securities pursuant to the Shelf Registration
Statement.

            (h) Upon the occurrence of any Material Event during the period for
which the Company is required to maintain an effective Shelf Registration
Statement, the Company shall, as promptly as practicable, prepare and file, if
necessary pursuant to applicable law, a post-effective amendment to the Shelf
Registration Statement or an amendment or supplement to the Prospectus and any
other required document that would be incorporated by reference into such shelf
Registration Statement and Prospectus so that, as thereafter delivered to
Holders or purchasers of the Securities, the Shelf Registration Statement, the
Prospectus and documents incorporated therein will not contain an 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 light of the
circumstances under which they were made, not misleading. If the Company
provides a Deferral Notice to the Holders to suspend the use of the Prospectus,
Holders shall suspend use of such Prospectus, and the two-year period of
effectiveness of the Shelf Registration Statement provided for in Section 1(b)
above shall be extended by the number of days from and including the date of the
giving of such notice to and including the date when the Initial Purchasers and
the Holders shall have been advised by the Company that the Prospectus may be
used or have received such amended or supplemented prospectus pursuant to this
Section 2(h).

            (i) Not later than the effective date of the Shelf Registration
Statement, the Company will provide CUSIP numbers for the Notes and the Common
Stock registered under the Shelf Registration Statement, and, subject to the
terms of the Indenture, provide the Trustee with printed certificates for such
Notes, in a form eligible for deposit with The Depository Trust Company.

                                      - 5 -
<PAGE>

            (j) The Company will comply with all rules and regulations of the
Commission to the extent and so long as they are applicable to the Shelf
Registration and will make generally available to its security holders (or
otherwise provide in accordance with Section 11(a) of the Securities Act) an
earnings statement satisfying the provisions of Section 11(a) of the Securities
Act, no later than 45 days after the end of a 12-month period (or 90 days, if
such period is a fiscal year) beginning with the first month of the Company's
first fiscal quarter commencing after the effective date of the Shelf
Registration Statement, which statement shall cover such 12-month period.

            (k) The Company shall cause the Indenture to be qualified under the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), in a timely
manner and containing such changes, if any, as shall be necessary for such
qualification. In the event that such qualification would require the
appointment of a new trustee under the Indenture, the Company shall appoint a
new trustee thereunder pursuant to the applicable provisions of the Indenture.

            (l) The Company may require each Holder of Securities to be sold
pursuant to the Shelf Registration Statement to furnish to the Company all such
information regarding the Holder and the distribution of the Securities as the
Company may from time to time reasonably require for inclusion in the Shelf
Registration Statement, and the Company may exclude from such registration the
Securities of any Holder that fails to furnish such information within a
reasonable time after receiving such request. Each Holder agrees, by acquisition
of the Securities, to be bound by and to comply in all respects with its
obligations as a Holder under this Agreement and that no Holder of Securities
shall be entitled to have the Securities held by it covered by the Shelf
Registration Statement or to sell any of such Securities pursuant to the Shelf
Registration Statement or to receive a Prospectus relating thereto, unless such
Holder has furnished the Company with a Notice and Questionnaire as required in
accordance with Section 1(d) (including all 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 Securities
as may be required to be disclosed in the Shelf Registration Statement under
applicable law or pursuant to comments of the Commission or as the Company may
reasonably request.

            (m) The Company shall enter into such customary agreements
(including, if requested, an underwriting agreement in customary form) and take
all such other action, if any, as any Holder shall reasonably request in order
to facilitate the disposition of the Securities pursuant to the Shelf
Registration.

            (n) The Company shall (i) make reasonably available for inspection
by the Holders, any underwriter participating in any disposition pursuant to the
Shelf Registration Statement and any attorney, accountant or other agent
retained by the Holders or any such underwriter all relevant financial and other
records, pertinent corporate documents and properties of the Company and (ii)
cause the Company's officers, directors, employees, accountants and auditors to
supply all relevant information reasonably requested by the Holders or any such
underwriter, attorney, accountant or agent in connection with the Shelf
Registration Statement, in

                                      - 6 -
<PAGE>

each case, as shall be reasonably necessary to enable such persons, to conduct a
reasonable investigation within the meaning of Section 11 of the Securities Act;
provided, however, that the foregoing inspection and information gathering shall
be coordinated on behalf of the Holders by one counsel designated by and on
behalf of the Holders as described in Section 3 hereof.

            (o) The Company, if requested by any Notice Holder covered by the
Shelf Registration Statement, shall cause (i) its counsel to deliver an opinion
and updates thereof relating to the Securities in customary form addressed to
such Notice Holders and the managing underwriters, if any, thereof and dated, in
the case of the initial opinion, the effective date of such Shelf Registration
Statement (it being agreed that the matters to be covered by such opinion shall
include, without limitation, the good standing of the Company and its
subsidiaries; the qualification of the Company and its subsidiaries to transact
business as foreign corporations; the due authorization, execution and delivery
of the relevant agreement of the type referred to in Section 2(m) hereof; the
due authorization, execution, authentication and issuance, and the validity and
enforceability, of the Securities; the absence of governmental approvals
required to be obtained in connection with the Shelf Registration Statement, the
offering and sale of the applicable Securities, or any agreement of the type
referred to in Section 2(m) hereof; the compliance as to form of the Shelf
Registration Statement and any documents incorporated by reference therein and
of the Indenture with the requirements of the Securities Act and the Trust
Indenture Act, respectively; and a separate letter to such counsel's knowledge
as of the date of the opinion and as of the effective date of the Shelf
Registration Statement or most recent post-effective amendment thereto, as the
case may be regarding the absence from the Shelf Registration Statement and the
Prospectus included therein, as then amended or supplemented, and from any
documents incorporated by reference therein of an untrue statement of a material
fact or the omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading (in the case
of any such documents, in the light of the circumstances existing at the time
that such documents were filed with the Commission under the Exchange Act); (ii)
its officers to execute and deliver all customary documents and certificates and
updates thereof requested by any underwriters of the applicable Securities
(including a certificate as to the absence of material legal or governmental
proceedings involving the Company and its subsidiaries, to the knowledge of the
officer executing such certificate) and (iii) its independent registered public
accounting firm and the independent registered public accounting firm with
respect to any other entity for which financial information is provided in the
Shelf Registration Statement to provide to the Notice Holders and any
underwriter therefor a comfort letter in customary form and covering matters of
the type customarily covered in comfort letters in connection with primary
underwritten offerings, subject to receipt of appropriate documentation as
contemplated, and only if permitted, by Statement of Auditing Standards No. 72.

            (p) In the event that any broker-dealer registered under the
Exchange Act shall underwrite any Securities or participate as a member of an
underwriting syndicate or selling group or "assist in the distribution" (within
the meaning of the Conduct Rules (the "Rules") of the National Association of
Securities Dealers, Inc. ("NASD")) thereof, whether as a Holder of such
Securities or as an underwriter, a placement or sales agent or a broker or
dealer in respect thereof, or otherwise, the Company will assist such
broker-dealer in complying with the requirements of such Rules, including,
without limitation, by (i) if such Rules, including Rule 2720, shall so require,
engaging a "qualified independent underwriter" (as defined in Rule 2720)

                                      - 7 -
<PAGE>

to participate in the preparation of the Shelf Registration Statement relating
to such Securities, to exercise usual standards of due diligence in respect
thereto and, if any portion of the offering contemplated by such Shelf
Registration Statement is an underwritten offering or is made through a
placement or sales agent, to recommend the yield of such Securities, (ii)
indemnifying any such qualified independent underwriter to the extent of the
indemnification of underwriters provided in Section 5 hereof and (iii) providing
such information to such broker-dealer as may be required in order for such
broker-dealer to comply with the requirements of the Rules

            (q) The Company shall use its commercially reasonable efforts to
take all other steps necessary to effect the registration of the Securities
covered by the Shelf Registration Statement contemplated hereby.

            3. Registration Expenses.

            (a) All expenses incident to the Company's performance of and
compliance with this Agreement will be borne by the Company, regardless of
whether a Shelf Registration Statement is ever filed or becomes effective,
including without limitation, (i) all registration and filing fees and expenses;
(ii) all fees and expenses of compliance with federal securities and state "blue
sky" or securities laws; (iii) all expenses of printing (including printing
certificates for the Securities to be issued and printing of Prospectuses),
messenger and delivery services and telephone; (iv) all fees and disbursements
of counsel for the Company; (v) all application and filing fees in connection
with listing the Securities on a national securities exchange or automated
quotation system pursuant to the requirements hereof; and (vi) all fees and
disbursements of any independent registered public accounting firm referred to
in Section 2(o) (including the expenses of any special audit and comfort letters
required by or incident to such performance). The Company will bear its internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any person, including special
experts, retained by the Company.

            (b) In connection with the Shelf Registration Statement required by
this Agreement, the Company will reimburse the Notice Holders of Securities
covered by the Shelf Registration Statement, for the reasonable fees and
disbursements of not more than one counsel, designated by the Notice Holders of
a majority in aggregate principal amount of the Securities covered by the Shelf
Registration Statement (provided that Notice Holders of Common Stock issued upon
the conversion of the Notes shall be deemed to be Notice Holders of the
aggregate principal amount of Notes from which such Common Stock was converted)
to act as counsel for the Notice Holders in connection therewith.

            4. Indemnification.

            (a) The Company agrees to indemnify and hold harmless each Notice
Holder and each person, if any, who controls such Notice Holder within the
meaning of the Securities Act or the Exchange Act (each Notice Holder and such
controlling persons are referred to collectively as the "Notice Holder
Indemnified Parties") from and against any losses, claims, damages or
liabilities, joint or several, or any actions in respect thereof (including, but
not limited to, any losses, claims, damages, liabilities or actions relating to
purchases and sales of the

                                      - 8 -
<PAGE>

Securities) to which each Notice Holder Indemnified Party may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in the
Shelf Registration Statement or Prospectus including any document incorporated
by reference therein or in any amendment or supplement thereto or in any
preliminary prospectus or any issuer free-writing prospectus (as defined in Rule
433 under the Securities Act) (a "FWP"), in any "issuer information" (as defined
in Rule 433 under the Securities Act) of the Company, which issuer information
is required to be, or is, filed with the Commission, or any Prospectus together
with any combination of one or more FWPs, if any, related to any such
registration or in any filing prepared or executed by the Company (or based upon
written information furnished by or on behalf of the Company expressly for use
in such filing) in connection with the qualification of the offering under the
securities or other "blue sky" laws of any jurisdiction in which Registrable
Securities are offered ("Blue Sky Filing"), relating to the Shelf Registration,
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 shall reimburse, as incurred, the Notice
Holder Indemnified Parties for any legal or other expenses reasonably incurred
by the Notice Holder Indemnified Parties in connection with investigating or
defending any such loss, claim, damage, liability or action in respect thereof;
provided, however, that the Company shall not be liable in any such case to the
extent that such loss, claim, damage or liability arises out of or is based upon
any untrue statement or alleged untrue statement or omission or alleged omission
made in the Shelf Registration Statement or Prospectus or in any amendment or
supplement thereto or in any preliminary prospectus or FWP or in any issuer
information relating to the Shelf Registration (i) in reliance upon and in
conformity with written information pertaining to such Notice Holder and
furnished to the Company by or on behalf of such Notice Holder specifically for
inclusion therein or (ii) so made in the Prospectus used by such Notice Holder
after such time as the Company has advised such Notice Holder of such untrue
statement or omission or alleged untrue statement or omission and that the
filing of a post-effective amendment or supplement thereto was required until
such time as such post-effective amendment or supplement is so filed; provided
further, however, that this indemnity agreement will be in addition to any
liability which the Company may otherwise have to such Notice Holder Indemnified
Party. The Company shall also indemnify underwriters, their officers and
directors and each person who controls such underwriters within the meaning of
the Securities Act or the Exchange Act to the same extent as provided above with
respect to the indemnification of the Notice Holders of the Securities if
requested by such Notice Holders. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of any Notice Holder
Indemnified Party and shall survive the transfer of securities by such Holder or
underwriter and any termination of this Agreement.

            (b) Each Notice Holder, severally and not jointly, will, if the
securities held by it are included in Shelf Registration Statement, indemnify
and hold harmless the Company and each person, if any, who controls the Company
within the meaning of the Securities Act or the Exchange Act (each a "Company
Indemnified Party") from and against any losses, claims, damages or liabilities
or any actions in respect thereof, to which the Company Indemnified Party may
become subject under the Securities Act, the Exchange Act or otherwise, insofar
as such losses, claims, damages, liabilities or actions arise out of or are
based upon (i) (A) any untrue statement or alleged untrue statement of a
material fact contained in the Shelf Registration

                                      - 9 -
<PAGE>

Statement or in any amendment thereto or (B) the omission or alleged omission to
state therein a material fact necessary to make the statements therein not
misleading or (ii) (A) any untrue statement or alleged untrue statement of a
material fact contained in the prospectus or supplement thereto or in any
preliminary prospectus relating to the Shelf Registration, or (B) the omission
or alleged omission to state therein a material fact necessary to make the
statements therein, not misleading, but in each case only to the extent that the
untrue statement or omission or alleged untrue statement or omission was made in
reliance upon and in conformity with written information pertaining to such
Notice Holder and furnished to the Company by or on behalf of such Notice Holder
specifically for inclusion therein; and, subject to the limitations set forth
immediately preceding this clause and Section 4(c) hereof, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company Indemnified Party in connection with investigating or defending any such
loss, claim, damage, liability or action in respect thereof; provided, however,
that the aggregate amount which any such Notice Holder shall be required to pay
pursuant to this Section 4 shall in no event be greater than the amount of the
net proceeds received by such Notice Holder upon the sale of the Securities
pursuant to the Shelf Registration Statement or Prospectus giving rise to such
claims less all amounts previously paid by such Notice Holder with respect to
any such claims. This indemnity agreement will be in addition to any liability
which such Notice Holder may otherwise have to the Company Indemnified Party.
Such indemnity shall survive the transfer of securities by such Notice Holder
and any termination of this Agreement.

            (c) Promptly after receipt by an indemnified party under this
Section 4 of notice of the commencement of any action, claim or proceeding
(including a governmental investigation), such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 4, notify the indemnifying party of the commencement thereof; but the
failure to notify the indemnifying party shall not relieve the indemnifying
party from any liability that it may have under subsection (a) or (b) above
except to the extent that it has been materially and actually prejudiced by such
failure; provided further that the failure to notify the indemnifying party
shall not relieve it from any liability that it may have to an indemnified party
otherwise than under subsection (a) or (b) above (it being understood that this
sentence is not intended to modify or alter in any way the rights of the
indemnified party or the obligations of the indemnifying party with respect to
such other liability). In case any such action, claim or proceeding is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, which consent shall not be unreasonably withheld or
delayed, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof the indemnifying party will not be liable to such indemnified
party under this Section 4 for any legal or other expenses, other than
reasonable costs of investigation, subsequently incurred by such indemnified
party in connection with the defense thereof. It is understood and agreed that
the indemnifying party shall not, 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 reasonably necessary local counsel)
for all indemnified parties, and that all such reasonable fees and expenses
shall be paid or reimbursed as they are incurred. Any such separate firm for the
Notice Holder Indemnified Parties shall be designated in

                                     - 10 -
<PAGE>

writing by the Notice Holder Indemnified Parties and any such separate firm for
the Company Indemnified Parties shall be designated in writing by the Company.
The indemnifying party shall not be liable for any settlement effected without
its written consent unless (i) such settlement is entered into in good faith by
the indemnified party more than 45 days after receipt by such indemnifying party
of written notice of the proposed settlement, (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 for any fees and expenses for which the
indemnified party is entitled to and has requested indemnification hereunder
prior to the date of such settlement. No indemnifying party shall, without the
prior written consent of the indemnified party, which consent shall not be
unreasonably withheld or delayed, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement (i) includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action, (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
and (iii) does not provide for any action on the part of any indemnified party
other than the payment of money damages which are to be paid in full by the
indemnifying party.

            (d) If the indemnification provided for in this Section 4 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in
subsection (a) or (b) above in such proportion as is appropriate to reflect the
relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements, omissions or
actions that resulted in such losses, claims, damages or liabilities (or actions
in respect thereof) as well as any other relevant equitable considerations. The
relative fault of the parties shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or such Notice Holder or such other
indemnified party, as the case may be, on the other, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement, omission or action. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any proceeding, action or claim which is the subject
of this subsection (d). Notwithstanding any other provision of this Section
4(d), the Notice Holders shall not be required to contribute any amount in
excess of the amount by which the net proceeds received by such Notice Holders
from the sale of the Securities pursuant to the Shelf Registration Statement
exceeds the amount of damages which such Notice Holders have 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 paragraph (d), each person, if any, who
controls such indemnified party within the meaning of the Securities Act or the
Exchange Act shall have the same rights to contribution as such indemnified
party and each person, if any, who controls the Company within the

                                     - 11 -
<PAGE>

meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company.

            (e) The agreements contained in this Section 4 shall survive the
sale of the Securities pursuant to the Shelf Registration Statement and shall
remain in full force and effect, regardless of any termination or cancellation
of this Agreement or any investigation made by or on behalf of any indemnified
party.

            5. Additional Interest Under Certain Circumstances.

            (a) The Company shall pay additional interest (the "Additional
Interest") to the holders of Transfer Restricted Securities as follows if any of
the following events occur (each such event in clauses (i) through (iii) below a
"Registration Default"):

                  (i) the Shelf Registration Statement has not been filed with
the Commission by the ninetieth (90th) day after the Closing Date;

                  (ii) the Shelf Registration Statement has not been declared
effective by the Commission by the one hundred and eightieth (180th) day after
the Closing Date; or

                  (iii) the Shelf Registration Statement is declared effective
by the Commission but (A) the Shelf Registration Statement thereafter ceases to
be effective or (B) the Shelf Registration Statement or the Prospectus ceases to
be usable in connection with resales of Transfer Restricted Securities (as
defined below) during the periods specified herein because (1) any event occurs
as a result of which the Prospectus forming part of such Shelf Registration
Statement would include any 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, (2) it shall be
necessary to amend such Shelf Registration Statement or supplement the related
prospectus, to comply with the Securities Act or the Exchange Act or the
respective rules thereunder or (3) such Shelf Registration Statement has expired
before a replacement Shelf Registration Statement has become effective.

Each of the foregoing will constitute a Registration Default whatever the reason
for any such event and whether it is voluntary or involuntary or is beyond the
control of the Company or pursuant to operation of law or as a result of any
action or inaction by the Commission.

      The Company shall pay Additional Interest to the Holders of the Notes that
are Transfer Restricted Securities over and above the interest set forth in the
title of the Notes from and including the date on which any such Registration
Default shall occur to but excluding the date on which all such Registration
Defaults have been cured; provided, that in no event shall the Company be
obligated to pay Additional Interest following the expiration of the Shelf
Registration Period; and provided further, however, that no such Additional
Interest shall accrue for or during any Suspension Period. Additional Interest
will accrue at a rate of (a) 0.25% (one quarter of one percent) of the principal
amount of such Notes per annum to and including the 90th day following the
occurrence of such Registration Default and (b) 0.50% (one half of one percent)
of the principal amount of such Notes per annum from and after the 91st day
following such Registration Default (such interest rates pursuant to clauses (a)
and (b), the "Additional

                                     - 12 -
<PAGE>

Interest Rate") No additional interest will accrue on any shares of Common Stock
into which Notes have been converted.

            (b) A Registration Default referred to in Section 5(a)(iii) hereof
shall be deemed not to have occurred and be continuing in relation to the Shelf
Registration Statement or the related Prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to the Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Notice Holders to use the related Prospectus or (y) other material events with
respect to the Company that would need to be described in such Shelf
Registration Statement or the related Prospectus and (ii) in the case of clause
(y), the Company is proceeding promptly and in good faith to amend or supplement
the Shelf Registration Statement and related Prospectus to describe such events;
provided, however, that in any case if such Registration Default occurs for a
continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured but in no event shall Additional
Interest accrue for or during any Suspension Period.

            (c) Any amounts of Additional Interest due pursuant to Section 5(a)
will be payable in cash semiannually in arrears on November 15 and May 15 (each,
an "Interest Payment Date") to Holders of record of the applicable Notes on the
preceding November 1 and May 1. The amount of Additional Interest will be
determined by multiplying the Additional Interest Rate by the principal amount
of the applicable Notes, further multiplied by a fraction, the numerator of
which is the number of days such Additional Interest Rate was applicable during
such period (determined on the basis of a 360 day year comprised of twelve
30-day months), and the denominator of which is 360. If a Holder converts its
Notes, all Additional Interest, if any, that has accrued since the Interest
Payment Date last preceding the date of conversion will be deemed to be paid in
full upon such conversion, and no separate payment will be made by the Company
upon conversion on account of such Additional Interest.

            (d) "Transfer Restricted Securities" means each Security until (i)
the date on which such Security has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (ii) the date on which such Security is distributed to the public
pursuant to Rule 144 under the Securities Act or assuming for this purpose that
the Holder thereof is not an affiliate of the Company, is saleable pursuant to
Rule 144(k) under the Securities Act.

            6. Rules 144 and 144A. The Company shall use its best efforts to
file the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time the Company is not required
to file such reports, it will, upon the request of any Holder, make publicly
available other information so long as necessary to permit sales of their
securities pursuant to Rules 144 and 144A. The Company covenants that it will
take such further action as any Holder may reasonably request, all to the extent
required from time to time to enable such Holder to sell Transfer Restricted
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rules 144 and 144A (including the requirements of
Rule 144A(d)(4)). Upon the request of any Holder, the Company shall deliver to
such Holder a written statement as to whether it has complied with such

                                     - 13 -
<PAGE>

requirements. Notwithstanding the foregoing, nothing in this Section 6 shall be
deemed to require the Company to register any of its securities pursuant to the
Exchange Act.

            7. Underwritten Registrations. If any of the Transfer Restricted
Securities covered by the Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will administer the offering ("Managing Underwriters") will be selected by
the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering (provided that Holders of
Common Stock issued upon conversion of the Notes shall not be deemed Holders of
Common Stock, but shall be deemed to be Holders of the aggregate principal
amount of Notes from which such Common Stock was converted).

            No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

            8. Miscellaneous.

            (a) Remedies. The Company acknowledges and agrees that any failure
by the Company to comply with its obligations under Section 1 hereof may result
in material irreparable injury to the Holders for which there is no adequate
remedy at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, any Holder may obtain such
relief as may be required to specifically enforce the Company's obligations
under Sections 1 hereof. The Company further agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

            (b) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, except by the Company and the written
consent of the Holders of a majority in principal amount of the Securities
affected by such amendment, modification, supplement, waiver or consents
(provided that Holders of Common Stock issued upon conversion of Notes shall not
be deemed Holders of Common Stock, but shall be deemed to be Holders of the
aggregate principal amount of Notes from which such Common Stock was converted).
Without the consent of the Holder of the Notes, however, no modification may
change the provisions relating to the payment of Additional Interest.

            (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, first-class mail,
facsimile transmission, or air courier which guarantees overnight delivery:

                  (1) if to a Holder that is not a Notice Holder, at the most
current address given by such Holder to the Company.

                  (2) if to a Notice Holder, at the most current address given
by such Notice Holder to the Company in a Notice and Questionnaire or any
amendment thereto.

courier guaranteeing next day delivery.

            (d) 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 is inconsistent with the rights
granted to the Holders herein or otherwise conflicts with the provisions hereof.

            (e) Successors and Assigns. This Agreement shall be binding upon the
Company and its successors and assigns.

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

together shall constitute one and the same agreement.

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

            (h) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD

Agreement, the parties hereto submit to the nonexclusive jurisdiction of any
federal or state court in the State of New York.

            (i) Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY

<PAGE>

INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT.

            (j) Severability. If any one or more of the provisions contained
herein, or the application thereof in any circumstance, is held invalid, illegal
or unenforceable, the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions contained
herein shall not be affected or impaired thereby.

            (k) Securities Held by the Company. Whenever the consent or approval
of Holders of a specified percentage of principal amount of Securities is
required hereunder, Securities held by the Company or its affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

            (l) Third Party Beneficiaries. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Purchasers, on the other hand, and shall have the right to enforce
such agreements directly to the extent they may deem such enforcement necessary
or advisable to protect their rights or the rights of Holders hereunder.

            If the foregoing is in accordance with your understanding of our
agreement, please sign and return to the Company a counterpart hereof, whereupon
this instrument, along with all counterparts, will become a binding agreement
among the several Purchasers and the Company in accordance with its terms.

                                    Very truly yours,

                                    C&D TECHNOLOGIES, INC.

                             C&D TECHNOLOGIES, INC.
             FORM OF SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

      The undersigned beneficial holder of 5.50% Convertible Senior Notes due
2026 (the "Notes") of C&D Technologies, Inc. (the "Company") and/or common
stock, $0.01 par value per share, issued or issuable upon conversion of the
Notes (the "Registrable Securities") understands that the Company has filed or
intends to file with the Securities and Exchange Commission (the "Commission") a
registration statement on 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 Securities, in accordance with the
terms of the registration rights agreement, dated as of November 21, 2006 (the
"Registration Rights Agreement"), among the Company and the Purchasers named
therein. A copy of the Registration Rights Agreement is available from the
Company upon request at the address set forth below. All capitalized terms not
otherwise defined herein shall have the meaning ascribed thereto in the
Registration Rights Agreement.

      Each beneficial holder of Registrable Securities, including beneficial
holders of Notes convertible into Registrable Securities (each a "beneficial
owner"), 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 prospectus to purchasers of Registrable Securities
and be bound by those provisions of the Registration Rights Agreement applicable
to such beneficial owner (including certain indemnification provisions as
described below). Beneficial owners that do not complete this Notice and
Questionnaire and deliver it to the Company as provided below will not be named
as selling securityholders in the prospectus and, therefore, will not be
permitted to sell any Registrable Securities pursuant to the Shelf Registration
Statement. Beneficial owners are required to complete and deliver this Notice
and Questionnaire at least one business day prior to the filing of the Shelf
Registration Statement so that such beneficial owners may be named as selling
securityholders in the related prospectus at the time of effectiveness. The
Company has agreed to pay additional amounts pursuant to the Registration Rights
Agreement under certain circumstances set forth therein.

      Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and the related prospectus.
Accordingly, holders and beneficial owners of Registrable Securities are advised
to consult their own securities law counsel regarding the consequences of being
named or not being named as a selling securityholder in the Shelf Registration
Statement and the related prospectus.

                                     NOTICE

      The undersigned beneficial owner (the "Selling Securityholder") of
Registrable Securities hereby gives notice to the Company of its intention to
sell or otherwise dispose of Registrable Securities beneficially owned by it and
listed below in Item 3 (unless otherwise specified under such Item 3) pursuant
to the Shelf Registration Statement. The undersigned, by signing and

                                      A-1
<PAGE>

returning this Notice and Questionnaire, understands that it will be bound by
the terms and conditions of this Notice and Questionnaire and the Registration
Rights Agreement.

      Pursuant to the Registration Rights Agreement, the undersigned has agreed
to indemnify and hold harmless the Company's directors and officers and each
person, if any, who controls the Company within the meaning of either Section 15
of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), from and against certain losses arising in
connection with statements concerning the undersigned that are made in the
Company's Shelf Registration Statement or the related prospectus in reliance
upon the information provided in this Notice and Questionnaire.

      If the Selling Securityholder transfers all or any portion of the
Registrable Securities listed in Item 3 below after the date on which such
information is provided to the Company, the Selling Securityholder agrees to
notify the transferee(s) at the time of the transfer of its rights and
obligations under this Notice and Questionnaire and the Registration Rights
Agreement.

5. Plan of Distribution.

      Except as set forth below, the undersigned (including its donees or
pledgees) intends to distribute the Registrable Securities listed above in Item
3 pursuant to the Shelf Registration Statement only as follows (if at all): Such
Registrable Securities may be sold from time to time directly by the undersigned
or, alternatively, through underwriters, broker-dealers or agents. If the
Registrable Securities are sold through underwriters, broker-dealers or agents,
the Selling Securityholder will be responsible for underwriting discounts or
commissions or agents' commissions. Such Registrable Securities may be sold in
one or more transactions at fixed prices, at prevailing market prices at the
time of sale, at varying prices determined at the time of sale or at negotiated
prices. Such sales may be effected in transactions (which may involve block
transactions) (i) on any national securities exchange or quotation service on
which the Registrable Securities may be listed or quoted at the time of sale,
(ii) in the over-the-counter market, or (iii) in transactions otherwise than on
such exchanges or services or in the over-the-counter market. The Selling
Securityholder may pledge or grant a security interest in some or all of the
Registrable Securities owned by it and, if it defaults in the performance of its
secured obligations, the pledgees or secured parties may offer and sell the
Registrable Securities from time to time pursuant to the prospectus. The Selling
Securityholder also may transfer and donate the Registrable Securities in other
circumstances in which case the transferees, donees, pledgees or other
successors in interest will be the selling securityholder for purposes of the
prospectus.

State any exceptions here:

________________________________________________________________________________

________________________________________________________________________________

Note: In no event will such method(s) of distribution take the form of an
underwritten offering of the Registrable Securities without the prior written
agreement of the Company.

      The undersigned acknowledges its obligation to comply with the provisions
of the Exchange Act and the rules thereunder relating to stock manipulation,
particularly Regulation M thereunder (or any successor rules or regulations), in
connection with any offering of Registrable Securities pursuant to the
Registration Rights Agreement. The undersigned agrees that neither it nor any
person acting on its behalf will engage in any transaction in violation of such
provisions.

      The undersigned beneficial owner and selling securityholder hereby
acknowledges its obligations under the Registration Rights Agreement to
indemnify and hold harmless certain persons as set forth therein. Pursuant to
the Registration Rights Agreement, the Company has agreed under certain
circumstances to indemnify the undersigned beneficial owner and selling
securityholder against certain liabilities.

      In accordance with the undersigned's obligation under the Registration
Rights Agreement to provide such information as may be required by law for
inclusion in the Shelf Registration Statement, the undersigned agrees to
promptly notify the Company of any inaccuracies or changes in the information
provided herein that may occur subsequent to the date hereof at any time while
the Shelf Registration Statement remains effective.

any date shall include, without duplication, any Additional Interest accrued or
payable as of such date as provided in the Registration Rights Agreement.

      "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control"
(including, with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as used with respect to any Person, shall mean

exchange.

      "Applicable Stock Price" on a Trading Day means the Volume-Weighted
Average Price per share of Common Stock (or any security into which the Common
Stock has been converted in connection with a Fundamental Change) on such

average of the bid and ask prices or, if there is more than one bid or ask
price, the average of the average bid and the average ask prices) on such
Trading Day as reported in composite transactions on the NYSE or, if the Common
Stock is not listed on the NYSE, on the principal United States securities
exchange on which the Common Stock is then traded or, if the Common Stock is not
listed on a United States national or regional securities exchange, as reported
by the National Association of Securities Dealers Automated Quotation system
("Nasdaq") or, if the Common Stock is not quoted on Nasdaq, as available in any
other over-the-counter market or, if not available on any over-the-counter
market, the Closing Sale Price shall be such price as the Board of Directors of
the Company shall determine in good faith.

      "Common Stock" means any stock of any class of the Company which has no
preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding-up of the Company

include only shares of the class designated as Common Stock of the Company, par
value $0.01 per share, at the date of this Indenture or shares of any class or
classes resulting from any reclassification or reclassifications thereof and
which have no preference in respect of dividends or of amounts payable in the
event of any voluntary or involuntary liquidation, dissolution or winding-up of
the Company and which are not subject to redemption by the Company; provided,
however, that if at any time there shall be more than one such resulting class,
the shares of each such class then so issuable shall be substantially in the
proportion which the total number of shares of such class resulting from all
such reclassifications bears to the total number of shares of all such classes
resulting from all such reclassifications.

      "Company" means the party named as such in the first paragraph of this
Indenture until a successor replaces it pursuant to the applicable provisions of
this Indenture, and thereafter "Company" shall mean such successor Company.

Registrar shall keep a register of the Securities ("Register") and of their
transfer and exchange.

      The Company may have one or more co-registrars, one or more additional
paying agents, and one or more additional conversion agents. The term
"Registrar" includes any co-registrar, including any named pursuant to Section
9.6. The term "Paying Agent" includes any additional paying agent, including any
named pursuant to Section 9.6. The term "Conversion Agent" includes any
additional conversion agent, including any named pursuant to Section 9.6.

      The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any Agent not a party to this Indenture.
If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent
or agent for service of notices and demands in any place required by this
Indenture, or fails to give the foregoing notice, the Trustee shall act as such.
The Company or any Affiliate of the Company may act as Paying Agent.

      The Company hereby initially appoints the Trustee as Registrar, Paying
Agent and Conversion Agent in connection with the Securities.

Section 2.4. Paying Agent to Hold Money and Securities in Trust

      Prior to 10:00 a.m., New York City time, on each due date of payments in
respect of, or delivery of Common Stock, Cash or other consideration or any
combination thereof, as applicable and as provided herein, upon conversion of,
any Security, the Company shall deposit with the Paying Agent Cash (in
immediately available funds if deposited on the due date) and/or with the
Conversion Agent such number of shares of Common Stock and/or other
consideration sufficient to make such payments or deliveries when so becoming
due. The Company shall require each Paying Agent or Conversion Agent, as
applicable (other than the Trustee), to agree in writing that such Agent shall
hold in trust for the benefit of Securityholders or the Trustee all Cash, Common
Stock and/or other consideration, as applicable, held by such Agent for the
making of payments or deliveries in respect of the Securities and shall notify
the Trustee in writing of any default by the Company in making any such payment
or delivery. If the Company or an Affiliate of the Company acts as Paying Agent
or Conversion Agent, as applicable, it shall segregate the Cash, Common Stock
and other consideration, as applicable, held by it as Paying Agent or Conversion
Agent, as applicable, and hold it as a separate trust fund.

      The Company at any time may require a Paying Agent or Conversion Agent, as
applicable, to pay all Cash, Common Stock or other consideration, as applicable,
held by it to the Trustee, and the Trustee may at any time during the
continuance of any Default, upon written request to the Paying Agent or the
Conversion Agent, as applicable, require such Paying Agent or Conversion Agent,
as applicable, to pay forthwith to the Trustee all Cash, Common Stock or other
consideration, as applicable, so held in trust by such Paying Agent or
Conversion Agent. Upon doing so, the Paying Agent or the Conversion Agent, as
applicable, shall have no further liability for such Cash, Common Stock or other
consideration, as applicable.

Section 2.5. Securityholder Lists

      The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
the Securityholders. If the Trustee is not the Registrar, the Company shall
furnish to the Trustee on or before each Interest Payment Date, and at such
other times as the Trustee may request in writing, a list of the names and
addresses of the Securityholders in such form and as of such date as the Trustee
may reasonably request.

Section 2.6. Transfer and Exchange

      (a) Subject to compliance with any applicable additional requirements
contained in Section 2.12, when a Security is presented to a Registrar with a
request to register a transfer thereof or to exchange such Security for an equal
principal amount of Securities of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested; provided,
however, that every Security presented or surrendered for registration of
transfer or exchange shall, if such Security is a Certificated Security, be duly
endorsed or accompanied by an assignment form, in the form included in Exhibit A
attached hereto and, if applicable, a transfer certificate, in the form included
in Exhibit B attached hereto, and in form reasonably satisfactory to the
Registrar duly executed by the Holder thereof or its attorney duly authorized in
writing. To permit registration of transfers and exchanges, upon surrender of
any Security for registration of transfer or exchange at an office or agency
maintained pursuant to Section 2.3, the Company shall execute and the Trustee
shall authenticate Securities of a like aggregate principal amount at the
Registrar's request. Any exchange or transfer shall be without charge, except
that the Company or the Registrar may require payment of a sum sufficient to
cover any tax, assessment or other governmental charge that may be imposed in
relation thereto, other than exchanges pursuant to Section 2.10, Section 13.5,
Article 3, Article 5 or Article 7, in each case, not involving any transfer.

      Neither the Company, any Registrar nor the Trustee shall be required to
exchange or register a transfer of (i) any Securities for a period of 15 days
preceding any mailing of a notice of Securities to be redeemed, (ii) any
Securities or portions thereof selected or called for redemption (except, in the
case of redemption of a Security in part, the portion thereof not to be
redeemed) or (iii) any Securities or portions thereof in respect of which a Put
Notice has been delivered and not validly withdrawn by the Holder thereof
(except, in the case of the purchase of a Security in part, the portion thereof
not to be purchased).

      All Securities issued upon any transfer or exchange of Securities shall be
valid obligations of the Company, evidencing the same debt and entitled to the
same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

      (b) Any Registrar appointed pursuant to Section 2.3 or Section 9.6 hereof
shall provide to the Trustee such information as the Trustee may reasonably
request in connection with the delivery by such Registrar of Securities upon
transfer or exchange of Securities.

      The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between

                                      -13-
<PAGE>

or among Agent Members or other beneficial owners of interests in any Global
Security) other than to require delivery of such opinions of counsel,
certificates and other documentation or evidence as are expressly required by,
and to do so if and when expressly required by the terms of, this Indenture
(including if so requested by the Company exercising a right to require the
delivery of such items), and to examine the same to determine substantial
compliance as to form with the express requirements hereof.

      Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book-entry system maintained by the Depository
(or its agent), and that ownership of a beneficial interest in a Global Security
shall be required to be reflected in a book-entry system.

Section 2.7. Replacement Securities

      If (a) any mutilated security is surrendered to the Company, a Registrar
or the Trustee, or (b) the Company, the Registrar and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Security, and, in either case, there is delivered to the Company, the Registrar
and the Trustee such security or indemnity as shall be reasonably required by
them to save each of them harmless, then, in the absence of notice to the
Company, such Registrar or the Trustee that such Security has been acquired by a
bona fide or protected purchaser, the Company shall issue, and the Trustee
shall, upon receipt of a Company Order (which the Company agrees to deliver
promptly), authenticate and deliver, in exchange for any such mutilated Security
or in lieu of any such destroyed, lost or stolen Security, a new Security of
like tenor and principal amount, bearing a number not contemporaneously
outstanding.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, or is about to be redeemed pursuant to
Article 3 or purchased by the Company pursuant to Article 5, the Company in its
discretion may, instead of issuing a new Security, pay, redeem or purchase such
Security, as the case may be, in accordance herewith.

      Upon the issuance of any new Securities under this Section 2.7, the
Company may require the payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in relation thereto and any
other reasonable expenses (including the reasonable fees and expenses of the
Trustee or the Registrar) in connection therewith.

      Every new Security issued pursuant to this Section 2.7 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued and outstanding
hereunder.

      The provisions of this Section 2.7 are (to the extent lawful) exclusive
and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities.

Section 2.8. Outstanding Securities

      Securities outstanding at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those paid, redeemed or repurchased
pursuant to Section 2.7, those delivered to it for cancellation and those
described in this Section 2.8 as not outstanding.

      If a Security is replaced pursuant to Section 2.7 (other than a mutilated
Security surrendered for replacement), it ceases to be outstanding unless the
Trustee receives, subsequent to the new Security's authentication, proof
satisfactory to the Company that the replaced Security is held by a bona fide or
protected purchaser. A mutilated Security ceases to be outstanding upon
surrender and replacement thereof pursuant to Section 2.7.

      If the Paying Agent holds, in accordance with the terms of this Indenture,
prior to 10:00 a.m., New York City time, on the Final Maturity Date or a
Redemption Date or on a Put Purchase Date, as the case may be, Cash sufficient
to pay all Securities then payable, then on and after such Final Maturity Date,
Redemption Date or Put Purchase Date, as the case may be, such Securities shall
cease to be outstanding and interest on such Securities shall cease to accrue.

      If a Security is converted in accordance with Article 7, then on the
Conversion Date, such Security shall cease to be outstanding and interest on
such Security shall cease to accrue, unless there shall be a default in the
delivery of the consideration payable hereunder upon such conversion.

      Subject to the restrictions contained in Section 2.9, a Security does not
cease to be outstanding solely because the Company or an Affiliate of the
Company holds the Security.

Section 2.9. Treasury Securities

      In determining whether the Holders of the required principal amount of
Securities have given or concurred in any notice, request, demand,
authorization, direction, waiver or consent, Securities owned by the Company or
any other obligor on the Securities or by any Affiliate of the Company or of
such other obligor shall be disregarded and deemed not to be outstanding for
such purposes, except that, for purposes of determining whether the Trustee
shall be protected in relying on any such notice, request, demand,
authorization, direction, waiver or consent, only Securities which a Trust
Officer actually knows are so owned shall be so disregarded. Securities so owned
which have been pledged in good faith shall not be disregarded if the pledgee
establishes to the satisfaction of the Trustee the pledgee's right so to act
with respect to the Securities and that the pledgee is not, and is not acting on
the behalf of, the Company or any other obligor on the Securities or any
Affiliate of the Company or of such other obligor.

Section 2.10. Temporary Securities

      Until definitive Securities are ready for delivery, the Company may
prepare and execute, and, upon receipt of a Company Order, the Trustee shall
authenticate and deliver, temporary Securities. Temporary Securities shall be
substantially in the form of definitive Securities but may have variations that
the Company with the consent of the Trustee reasonably considers appropriate for
temporary Securities. After the preparation of definitive Securities, the

                                      -15-
<PAGE>

temporary Securities shall be exchangeable for definitive Securities upon
surrender of the temporary Securities at the office or agency of the Company
designated for such purpose pursuant to Section 2.3, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities,
the Company shall execute and the Trustee shall, upon receipt of a Company Order
(which the Company agrees to deliver promptly), authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of authorized
denominations. Until so exchanged the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities.

Section 2.11. Cancellation

      The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent shall
forward to the Trustee or its agent any Securities surrendered to them for
transfer, exchange, redemption, payment or conversion. The Trustee and no one
else shall cancel, in accordance with its standard procedures, all Securities
surrendered for transfer, exchange, redemption, payment, conversion or
cancellation and shall deliver the canceled Securities to the Company. The
Company may not issue new Securities to replace Securities that it has paid or
delivered to the Trustee for cancellation or that any Holder has converted
pursuant to Article 7.

      All Securities that are redeemed or purchased pursuant to Articles 3 or 5
or otherwise acquired by the Company shall be delivered to the Trustee for
cancellation. If the Company shall acquire any of the Securities, such
acquisition shall not operate as a repurchase or satisfaction of the
indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

Section 2.12. Legend; Additional Transfer and Exchange Requirements

      (a) Transfer and Exchange of Global Securities.

      (i) Certificated Securities shall be issued in exchange for interests in
the Global Securities only (x) if the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the Global Securities or if it
at any time ceases to be a "clearing agency" registered under the Exchange Act,
if so required by applicable law or regulation, and a successor Depositary is
not appointed by the Company within 90 days of such notice or (y) if an Event of
Default has occurred and is continuing, each in accordance with the Applicable
Procedures. In any such case, the Company shall execute, and the Trustee shall,
upon receipt of a Company Order (which the Company agrees to deliver promptly),
authenticate and deliver Certificated Securities in an aggregate principal
amount equal to the principal amount of such Global Securities in exchange
therefor. Only Restricted Certificated Securities shall be issued in exchange
for beneficial interests in Restricted Global Securities, and only Unrestricted
Certificated Securities shall be issued in exchange for beneficial interests in
Unrestricted Global Securities. Certificated Securities issued in exchange for
beneficial interests in Global Securities shall be registered in such names and
shall be in such authorized denominations as the Depositary, pursuant to
instructions from its Agent Members or otherwise in accordance with the
Applicable Procedures, shall instruct the Trustee. The Trustee shall deliver or
cause to be delivered such Certificated Securities to the Persons in whose name
such Securities are so

                                      -16-
<PAGE>

registered. Such exchange shall be effected in accordance with the Applicable
Procedures. In the event that the Certificated Securities are not issued to each
such beneficial owner promptly after the Registrar has received a request from
the Depositary to issue such Certificated Securities, the Company expressly
acknowledges, with respect to the right of any Holder to pursue a remedy
pursuant to Section 11.6 or 11.7 hereof, the right of any beneficial holder of
Securities to pursue such remedy with respect to the portion of the Global
Security that represents such Beneficial Owner's Securities as if such
Certificated Notes had been issued.

      (ii) Notwithstanding any other provisions of this Indenture other than the
provisions set forth in Section 2.12(a)(i), a Global Security may not be
transferred except as a whole by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

      (b) Transfer and Exchange of Certificated Securities. In the event that
Certificated Securities are issued in exchange for beneficial interests in
Global Securities in accordance with Section 2.12(a)(i), and, on or after such
event, Certificated Securities are presented by a Holder to the Registrar with a
request:

            (x) to register the transfer of the Certificated Securities to a
      person who will take delivery thereof in the form of Certificated
      Securities only; or

            (y) to exchange such Certificated Securities for an equal principal
      amount of Certificated Securities of other authorized denominations,

such Registrar shall register the transfer or make the exchange as requested;
provided, however, that the Certificated Securities presented or surrendered for
register of transfer or exchange:

            (i) shall be duly endorsed or accompanied by a written instrument of
      transfer in accordance with the proviso to the first sentence of Section
      2.6(a); and

            (ii) in the case of a Restricted Certificated Security, such request
      shall be accompanied by the following additional information and
      documents, as applicable:

                  (1) if such Restricted Certificated Security is being
            delivered to the Registrar by a Holder for registration in the name
            of such Holder, without transfer, or such Restricted Certificated
            Security is being transferred to the Company or a Subsidiary of the
            Company, a certification to that effect from such Holder (in
            substantially the form set forth in Exhibit B);

                  (2) if such Restricted Certificated Security is being
            transferred to a person the Holder reasonably believes is a QIB in
            accordance with Rule 144A, or pursuant to an effective registration
            statement under the Securities Act, a certification to that effect
            from such Holder (in substantially the form set forth in Exhibit B);

                                      -17-
<PAGE>

                  (3) if such Restricted Certificated Security is being
            transferred pursuant to an exemption from the registration
            requirements of the Securities Act in accordance with Rule 144 or
            pursuant to and in compliance with another exemption from the
            registration requirements under the Securities Act, a certification
            to that effect from the Holder (in substantially the form set forth
            in Exhibit B) and, if the Company or the Registrar so requests, an
            opinion of counsel, certificates and other information reasonably
            acceptable to the Company and the Registrar to the effect that such
            transfer does not require registration under the Securities Act.

      (c) Transfer of a Beneficial Interest in a Restricted Global Security for
a Beneficial Interest in an Unrestricted Global Security. Any person having a
beneficial interest in a Restricted Global Security may upon request, subject to
the Applicable Procedures, transfer such beneficial interest to a Person who is
required or permitted to take delivery thereof in the form of a beneficial
interest in an Unrestricted Global Security. Upon receipt by the Trustee of
written instructions, or such other form of instructions as is customary for the
Depositary, from the Depositary or its nominee on behalf of any Person having a
beneficial interest in a Restricted Global Security and the following additional
information and documents in such form as is customary for the Depositary from
the Depositary or its nominee on behalf of the Person having such beneficial
interest in the Restricted Global Security (all of which may be submitted by
facsimile or electronically):

            (i) if such beneficial interest is being transferred pursuant to an
      effective registration statement under the Securities Act, a certification
      to that effect from the Holder (in substantially the form set forth in
      Exhibit B); or

            (ii) if such beneficial interest is being transferred pursuant to an
      exemption from the registration requirements of the Securities Act in
      accordance with Rule 144, a certification to that effect from the Holder
      (in substantially the form set forth in Exhibit B) and, if the Company or
      the Trustee so requests, an opinion of counsel, certificates and other
      information reasonably acceptable to the Company and the Registrar to the
      effect that such transfer does not require registration under the
      Securities Act;

the Registrar shall reduce or cause to be reduced the aggregate principal amount
of the Restricted Global Security by the appropriate principal amount and shall
increase or cause to be increased the aggregate principal amount of the
Unrestricted Global Security by a like principal amount. Such transfer shall
otherwise be effected in accordance with the Applicable Procedures. If no
Unrestricted Global Security is then outstanding, the Company shall execute and
the Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver an Unrestricted Global Security.

      (d) Transfer of a Beneficial Interest in an Unrestricted Global Security
for a Beneficial Interest in a Restricted Global Security. Any person having a
beneficial interest in an Unrestricted Global Security may upon request, subject
to the Applicable Procedures, transfer such beneficial interest to a person who
is required or permitted to take delivery thereof in the form of a beneficial
interest in a Restricted Global Security. Upon receipt by the Trustee of written
instructions, or such other form of instructions as is customary for the
Depositary, from

                                      -18-
<PAGE>

the Depository or its nominee on behalf of any person having a
beneficial interest in an Unrestricted Global Security and the following
additional information and documents in such form as is customary for the
Depositary, from the Depositary or its nominee on behalf of the person having
such beneficial interest in the Unrestricted Global Security (all of which may
be submitted by facsimile or electronically):

            (i) a certification from the Holder (in substantially the form set
      forth in Exhibit B) to the effect that such beneficial interest is being
      transferred to a person that the transferor reasonably believes is a QIB
      in accordance with Rule 144A;

            (ii) if such beneficial interest in such Unrestricted Global
      Security is being transferred in compliance with any other exemption from
      registration under the Securities Act, certification to that effect from
      such Holder (in substantially the form set forth in Exhibit B) and, if the
      Company or the Trustee so requests, an opinion of counsel, certificates
      and other information reasonably acceptable to the Company and the
      Registrar to the effect that such transfer does not require registration
      under the Securities Act; or

            (iii) a certification (in substantially the form set forth in
      Exhibit B) to the effect that such beneficial interest is being
      transferred to the Company or a Subsidiary of the Company,

the Registrar shall reduce or cause to be reduced the aggregate principal amount
of the Unrestricted Global Security by the appropriate principal amount and
shall increase or cause to be increased the aggregate principal amount of the
Restricted Global Security by a like principal amount. Such transfer shall
otherwise be effected in accordance with the Applicable Procedures. If no
Restricted Global Security is then outstanding, the Company shall execute and
the Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver a Restricted Global Security.

      (e) Transfers of Certificated Securities for Beneficial Interest in Global
Securities. In the event that Certificated Securities are issued in exchange for
beneficial interests in Global Securities and, thereafter, the events or
conditions specified in Section 2.12(a)(i) which required such exchange shall
cease to exist, the Company shall mail notice to the Trustee and to the Holders
(i) stating that Holders may exchange Certificated Securities for interests in
Global Securities by complying with the procedures set forth in this Indenture
and (ii) briefly describing such procedures and the events or circumstances
requiring that such notice be given. Thereafter, if Certificated Securities are
presented by a Holder to a Registrar with a request:

            (x) to register the transfer of such Certificated Securities to a
      Person who will take delivery thereof in the form of a beneficial interest
      in a Global Security, which request shall specify whether such Global
      Security will be a Restricted Global Security or an Unrestricted Global
      Security; or

            (y) to exchange such Certificated Securities for an equal principal
      amount of beneficial interests in a Global Security, which beneficial
      interests will be owned by the Holder transferring such Certificated
      Securities (provided that in the case of such an

                                      -19-
<PAGE>

      exchange, Restricted Certificated Securities may be exchanged only for
      Restricted Global Securities and Unrestricted Certificated Securities may
      be exchanged only for Unrestricted Global Securities),

the Registrar shall register the transfer or make the exchange as requested by
canceling such Certificated Security and causing the aggregate principal amount
of the applicable Global Security to be increased accordingly and, if no such
Global Security is then outstanding, the Company shall issue and the Trustee
shall, upon receipt of a Company Order (which the Company agrees to deliver
promptly) authenticate and deliver a new Global Security; provided, however,
that the Certificated Securities presented or surrendered for registration of
transfer or exchange:

                  (i) shall be duly endorsed or accompanied by a written
            instrument of transfer in accordance with the proviso to Section
            2.6(a);

                  (ii) in the case of a Restricted Certificated Security to be

            information and documents, as applicable:

                        (1) if such Restricted Certificated Security is being

                  under the Securities Act, a certification to that effect from
                  such Holder (in substantially the form set forth in Exhibit
                  B); or

                        (2) if such Restricted Certificated Security is being

                  requirements of the Securities Act, including without
                  limitation the exemption provided by Rule 144 thereunder, a
                  certification to that effect from such Holder (in
                  substantially the form set forth in Exhibit B) and, if the

            Global Security, shall be accompanied by a certification to that
            effect from such Holder (in substantially the form set forth in
            Exhibit B):

                  (iv) in the case of an Unrestricted Certificated Security to
            be transferred or exchanged for a beneficial interest in an
            Unrestricted Global Security, or in the case of a Restricted

                        (1) if such Unrestricted Certificated Security is being
                  transferred to a person the Holder reasonably believes is a
                  QIB (which, in the case of an exchange, shall be such Holder)
                  in accordance with Rule 144A, a certification to that effect
                  from such Holder (in substantially the form set forth in
                  Exhibit B);

                        (2) if such Unrestricted Certificated Security is being
                  transferred in compliance with any other exemption from
                  registration under the Securities Act, certification to that
                  effect from such Holder (in substantially the form set forth
                  in Exhibit B) and, if the Company or the Trustee so requests,
                  an opinion of counsel, certificates and other information
                  reasonably acceptable to the Company and the Registrar to the
                  effect that such transfer does not require registration under
                  the Securities Act; or

                        (3) if such Unrestricted Certificated Security is being
                  transferred to the Company or a Subsidiary of the Company, a
                  certification to that effect from such Holder (in
                  substantially the form set forth in Exhibit B).

      (f) Legends.

      (i) Except as permitted by the following paragraphs (ii), (iii) and (iv),
each Global Security and Certificated Security (and all Securities issued in
exchange therefor or upon registration of transfer or replacement thereof) shall
bear a legend in substantially the form called for by footnote 2 to Exhibit A
attached hereto (the "Restricted Legend"), for so long as it is required by this
Indenture to bear such legend.

      (ii) Upon any sale or transfer of a Restricted Security (x) after the
expiration of the holding period applicable to sales of the Securities under
Rule 144(k) of the Securities Act, (y) pursuant to Rule 144 or another exemption
from the registration requirements of the Securities Act pursuant to which the
transferee is permitted to transfer such Restricted Securities without
restriction or (z) pursuant to an effective registration statement under the
Securities Act:

                  (1) in the case of any Restricted Certificated Security, each
            Registrar shall permit the Holder thereof to transfer such
            Restricted Certificated Security to a transferee who, unless such
            transferee is an Affiliate of the Company, shall take such Security
            in the form of an Unrestricted Certificated Security or (under the
            circumstances described in Section 2.12(e)) an Unrestricted Global
            Security, and in each case shall rescind any restriction on the
            transfer of such Security; provided, however, that the Holder of
            such Restricted Certificated Security shall,

                                      -21-
<PAGE>

            in connection with such exchange or transfer, comply with the other
            applicable provisions of this Section 2.12; and

                  (2) in the case of a Restricted Global Security, each
            Registrar shall permit the Holder of a beneficial interest therein
            to transfer such beneficial interest in a Restricted Global Security
            to a transferee who, unless such transferee is an Affiliate of the
            Company, shall take such Security in the form of a beneficial
            interest in an Unrestricted Global Security and shall rescind any
            restriction on transfer of such Security; provided, however, that
            such Unrestricted Global Security shall continue to be subject to
            the provisions of Section 2.12(a)(ii); and provided further,
            however, that the owner of such beneficial interest shall, in
            connection with such transfer, comply with the other applicable
            provisions of this Section 2.12.

If the Registrar so requests or if the Applicable Procedures so require, prior
to the removal of any restrictive legend at the end of the holding period
applicable to sales of the Securities under Rule 144(k) of the Securities Act,
such requesting Holder shall deliver an Opinion of Counsel in form reasonably
acceptable to the Registrar and the Company to the effect that the restrictions
on transfer contained herein and the restrictive legend are no longer required
in order to maintain compliance with the Securities Act.

      (iii) Upon the exchange, registration of transfer or replacement of
Securities not bearing the Restricted Legend, the Company shall issue, and the
Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver, Securities that do not bear such
Restricted Legend.

      (iv) After the expiration of the holding period pursuant to Rule 144(k) of
the Securities Act, the Company may with the consent of any Holder of a
Restricted Global Security or a Restricted Certificated Security that is not an
Affiliate of the Company, remove any restriction of transfer on such Security,
and the Company shall issue, and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), authenticate and deliver
Securities that do not bear the Restricted Legend.

      (v) Until the earliest to occur of (w) the expiration of the holding
period applicable to sales of the Securities under Rule 144(k) of the Securities
Act, (x) a transfer pursuant to Rule 144 or another exemption from the
registration requirements of the Securities Act pursuant to which the transferee
is permitted to transfer such Restricted Securities without restriction, (y) a
transfer pursuant to an effective registration statement under the Securities
Act or (z) the inclusion of such shares in an effective registration statement
under the Securities Act and the delivery by the holder thereof to the Company
of an undertaking in form and substance reasonably satisfactory to the Company
that such holder will not transfer or otherwise dispose of such shares except
pursuant to such registration statement and in compliance with any prospectus
delivery requirements under the Securities Act, the shares of Common Stock
issued upon conversion of the Securities shall bear a legend substantially to
the same effect as the Restricted Legend; provided that all Securities held by
Affiliates of the Company shall bear the Restricted Legend at all times.

                                      -22-

      (g) Transfers to the Company. Nothing contained in this Indenture or in
the Securities shall prohibit the sale or other transfer of any Securities
(including beneficial interests in Global Securities) to the Company, or any of
its Subsidiaries or any of its Affiliates; provided, however, that neither the
Company nor any of its Subsidiaries shall resell or otherwise transfer any such
Security.

Section 2.13. CUSIP Numbers

      The Company in issuing the Securities may use one or more "CUSIP," "ISIN"
or other similar numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP," "ISIN" or other similar numbers in notices of redemption or
purchase as a convenience to Holders; provided, however, that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption or purchase and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption or
purchase shall not be affected by any defect in or omission of such numbers. The
Company shall promptly notify the Trustee of any change in the "CUSIP," "ISIN"
or other similar numbers.

Section 2.14. Ranking

      The obligations of the Company arising under or in connection with this
Indenture and every outstanding Security issued under this Indenture from time
to time constitutes and shall constitute a senior unsecured general obligation
of the Company, ranking equally with existing and future senior unsecured
indebtedness of the Company, including without limitation the Company's 5.25%
Convertible Senior Notes Due 2025, and ranking senior in right of payment to any
future indebtedness of the Company that is expressly made subordinate to the
Securities by the terms of such indebtedness.

Section 2.15. Persons Deemed Owners

      Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of, Redemption Price or Put
Price for, and interest on, the Security, for the purpose of receiving Common
Stock, Cash and, if applicable, any Make-Whole Premium upon conversion and for
all other purposes whatsoever, whether or not such Security is overdue, and none
of the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. The registered Holder of a Global Security
may grant proxies and otherwise authorize any person, including Agent Members
and persons that may hold interests through Agent Members, to take any action
that a Holder is entitled to take under this Indenture or the Securities.

Section 2.16. Defaulted Interest

      If the Company defaults on a payment of interest on the Securities, it
shall pay the defaulted interest, plus (to the extent permitted by law) any
interest payable on the defaulted interest, in accordance with the terms hereof,
to the Persons who are Holders on a subsequent

                                      -23-
<PAGE>

special record date, which date shall be at least five Business Days prior to
the payment date. The Company shall fix such special record date and payment
date in a manner satisfactory to the Trustee. At least 10 days before such
special record date, the Company shall mail to each Holder a notice that states
the special record date, the payment date and the amount of defaulted interest,
and interest payable on defaulted interest, if any, to be paid. The Company may
make payment of any defaulted interest in any other lawful manner not
inconsistent with the requirements (if applicable) of any securities exchange on
which the Securities may be listed and, upon such notice as may be required by
such exchange, if, after written notice given by the Company to the Trustee of
the proposed payment pursuant to this sentence, such manner of payment shall be
deemed practicable by the Trustee.

                                    ARTICLE 3

                                   REDEMPTION

Section 3.1. Redemption of Securities; Notice to Trustee

      (a) At any time on and after November 15, 2011, the Securities may be
redeemed at the option of the Company at any time or from time to time as
described below. Upon any redemption pursuant to this Section 3.1, the Company
shall provide the notice required by Section 3.3 hereof (which notice may be
revoked at any time prior to the time at which the Company or the Trustee, as
the case may be, has given such notice to Securityholders) and shall pay a
redemption price in Cash equal to 100% of the principal amount of the Securities
being redeemed, plus any accrued and unpaid interest (including Additional
Interest, if any) to, but excluding, the date fixed for redemption, payable in
Cash (the "Redemption Price").

      (b) In the event that the Company elects to redeem the Securities on a
Redemption Date that is after any Interest Payment Record Date but on or before
the corresponding Interest Payment Date or that results in the conversion of the
Securities prior to that Interest Payment Date, the Company shall be required to
pay any accrued and unpaid interest to the Holder who was the registered Holder
on the Interest Payment Record Date immediately preceding such Redemption Date
or conversion.

      (c) If the Company elects to redeem Securities pursuant to this Section
3.1 and paragraph 5 of the Securities, it shall notify the Trustee of the
Redemption Date and the principal amount of Securities to be redeemed at least
15 days prior to the date notice of the Redemption Date is given to the Holders
pursuant to Section 3.3 (unless a shorter notice shall be satisfactory to the
Trustee).

Section 3.2. Selection of Securities to be Redeemed

      If less than all of the Securities are to be redeemed, unless the
Applicable Procedures provide otherwise, the Trustee shall select the Securities
to be redeemed. The Trustee shall make the selection by lot, on a pro rata basis
or by any other method the Trustee considers fair and appropriate or in
accordance with the Applicable Procedures to the extent the Securities are
issued as Global Securities. Securities in denominations of $1,000 principal
amount may only be redeemed in whole. The Trustee may select for redemption
portions (equal to $1,000

                                      -24-
<PAGE>

principal amount or any integral multiple thereof) of the principal of
Securities that have denominations larger than $1,000 principal amount.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of the Securities to be
redeemed.

      Securities and portions of Securities that are to be redeemed are
convertible by the Holder until 5:00 p.m., New York City time, on the Business
Day immediately preceding the Redemption Date. If any Security selected for
partial redemption is converted in part before termination of the conversion
right with respect to the portion of the Security so selected, the converted
portion of such Security shall be deemed to be taken from the portion selected
for redemption. Securities that have been converted subsequent to the Trustee
commencing selection of Securities to be redeemed but prior to redemption of
such Securities shall be treated by the Trustee as outstanding for the purpose
of such selection.

Section 3.3. Notice of Redemption

      At least 30 days but not more than 60 days before a Redemption Date, the
Company shall mail or cause to be mailed a notice of redemption to each Holder
of Securities to be redeemed in accordance with Section 16.2.

      The notice shall identify the Securities (including the CUSIP number(s) of
the Securities) to be redeemed and shall state:

                        (1) the Redemption Date;

                        (2) the Redemption Price;

                        (3) the then current Conversion Rate;

                        (4) the names and addresses of the Paying Agent and
                  Conversion Agent;

                        (5) that Securities called for redemption must be
                  presented and surrendered to the Paying Agent to collect the
                  Redemption Price;

                        (6) that Holders who wish to convert Securities must
                  surrender such Securities for conversion prior to 5:00 p.m.,
                  New York City time, on the Business Day immediately preceding
                  the Redemption Date and must satisfy the other requirements
                  set forth in paragraph 8 of the Securities and Article 7
                  hereof;

                        (7) that, unless the Company defaults in making the
                  payment of the Redemption Price, interest on Securities called
                  for redemption shall cease accruing on and after the
                  Redemption Date; and

                        (8) if any Security is being redeemed in part, the
                  portion of the principal amount of such Security to be
                  redeemed and that, after the Redemption

                                      -25-
<PAGE>

                  Date, upon presentation and surrender of such Security, a new
                  Security or Securities in aggregate principal amount equal to
                  the unredeemed portion thereof shall be issued.

      If any of the Securities to be redeemed is in the form of a Global
Security, then the Company shall modify such notice to the extent necessary to
accord with the Applicable Procedures applicable to redemptions.

      At the Company's written request, the Trustee shall give the notice of
redemption to each Holder in the Company's name and at the Company's expense;
provided, however, that the Company makes such request at least three Business
Days (unless a shorter period shall be satisfactory to the Trustee) prior to the
date by which such notice of redemption must be given to Holders in accordance
with this Section 3.3; provided further, however, that the text of the notice of
redemption shall be prepared by the Company.

Section 3.4. Effect of Notice of Redemption

      Once notice of redemption is mailed, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price stated
in the notice, except for Securities that are converted in accordance with the
provisions of this Indenture. Upon surrender to the Paying Agent, such
Securities shall be paid at the Redemption Price.

Section 3.5. Deposit of Redemption Price

      Prior to 10:00 a.m., New York City time, on the applicable Redemption
Date, the Company shall deposit with the Paying Agent (or, if the Company or an
Affiliate acts as Paying Agent, shall segregate and hold in trust as provided in
Section 2.4) an amount of Cash (in immediately available funds if deposited on
such Redemption Date) sufficient to pay the aggregate Redemption Price of all
Securities or portions thereof that are to be redeemed on that Redemption Date,
other than Securities or portions thereof called for redemption on that date
that have been delivered by the Company to the Trustee for cancellation or have
been delivered by the Holder thereof for conversion.

      If the Paying Agent holds, in accordance with the terms hereof, at 10:00
a.m., New York City time, on the applicable Redemption Date, Cash sufficient to
pay the Redemption Price of all Securities to be redeemed on such date, then, on
and after such Redemption Date, such Securities shall cease to be outstanding
and interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their Holders to the Paying Agent, and the rights of
the Holders in respect thereof shall terminate (other than the right to receive
the Redemption Price upon delivery of such Securities by their Holders to the
Paying Agent).

Section 3.6. Securities Redeemed in Part

      Any Certificated Security that is to be redeemed only in part shall be
surrendered at the office of the Paying Agent and, promptly after the Redemption
Date, the Company shall issue and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), authenticate and deliver
to the Holder of such Security without service charge a new

                                      -26-
<PAGE>

Security or Securities, of such authorized denomination or denominations as may
be requested by such Holder, in aggregate principal amount equal to, and in
exchange for, the portion of the principal amount of the Security so surrendered
that is not redeemed.

Section 3.7. Repayment to the Company

      To the extent that the aggregate amount of Cash deposited by the Company
pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Securities
or portions thereof that the Company is obligated to redeem on the Redemption
Date (because of the conversion of Securities pursuant to Article 7 or
otherwise) then, promptly after the Redemption Date, the Paying Agent shall
return any such excess Cash to the Company.

Section 5.1. Purchase of Securities at Option of the Holder upon a Fundamental
Change

      (a) In the event a Fundamental Change shall occur at any time when any
Securities remain outstanding, the Securities shall be purchased by the Company,
at the option of any Holder thereof, in accordance with the provisions of
paragraph 6 of the Securities on a date specified by the Company (the
"Fundamental Change Purchase Date") that is not less than 45 Business Days after
the date the Company mails the Fundamental Change Company Notice pursuant to
Section 5.1(b), at a purchase price in Cash equal to 100% of the principal
amount of the Securities tendered for purchase, plus accrued and unpaid interest
(including Additional Interest, if any) to, but not including, the Fundamental
Change Purchase Date (the "Fundamental Change Purchase Price"), subject to
satisfaction by or on behalf of any Holder of the requirements set forth in
Section 5.1(c).

      A "Fundamental Change" shall be deemed to have occurred upon the
occurrence of any of the following:

                  (1) any "person" or "group" files a Schedule 13D or Schedule
            TO, or any successor schedule, form or report under the Exchange
            Act, disclosing, or the Company otherwise becomes aware, that such
            person or group is or has become the "beneficial owner," directly or
            indirectly, of shares of the Company's voting Stock representing 50%
            or more of the total voting power of all outstanding classes of the
            Company's voting stock or has the power, directly or indirectly, to
            elect a majority of the members of the "board of directors" of the
            Company;

                  (2) the Company consolidates with, or merges with or into,
            another Person or the Company sells, assigns, conveys, transfers,
            leases or otherwise disposes of all or substantially all of the
            Company's assets, or any Person

                                      -27-
<PAGE>

            consolidates with, or merges with or into, the Company, in any such
            event other than pursuant to a transaction in which the Persons (the
            "Existing Shareholders") that "beneficially owned," directly or
            indirectly, shares of the Company's voting stock immediately prior
            to such transaction beneficially own, directly or indirectly, shares
            of voting stock representing a majority of the total voting power of
            all outstanding classes of voting stock of the surviving or
            transferee person in substantially the same proportion amongst such
            Existing Shareholders as such ownership immediately prior to such
            transaction;

                  (3) a majority of the members of the "board of directors" of
            the Company are not "continuing directors;"

                  (4) the Company's Common Stock ceases to be listed on the NYSE
            or another national securities exchange and is not then quoted on
            The Nasdaq Global Market or The Nasdaq Global Select Market or
            another established automated over-the-counter trading market in the
            United States; or

                  (5) the Company's Common Stock is suspended from trading on
            the NYSE or another national securities exchange or The Nasdaq
            Global Market or The Nasdaq Global Select Market or another
            established automated over-the-counter trading market in the United
            States and, in any such case, such suspension is not lifted within
            60 days after commencement thereof.

            Notwithstanding anything to the contrary set forth in this Section
      5.1, a merger or consolidation shall be deemed not to constitute a
      Fundamental Change if greater than 90% of the consideration (excluding
      Cash payments for fractional shares and Cash payments pursuant to
      dissenters' appraisal rights) in the merger or consolidation constituting
      the Fundamental Change consists of common stock traded on the NYSE or
      another national securities exchange or quoted on The Nasdaq Global Market
      or The Nasdaq Global Select Market (or which shall be so traded or quoted
      when issued or exchanged in connection with such merger or consolidation)
      and as a result of such transaction or transactions the Securities become
      convertible solely into shares of such common stock.

            o     "person" and "group" shall have the meanings given to them for
                  purposes of Sections 13(d) and 14(d) of the Exchange Act or

                  disposing of securities within the meaning of Rule 13d-5(b)(1)
                  under the Exchange Act, or any successor provision;

            o     a "beneficial owner" shall be determined in accordance with
                  Rule 13d-3 under the Exchange Act, as in effect on the date of
                  this Indenture;

            o     "beneficially own" and "beneficially owned" have meanings
                  correlative to that of beneficial owner;

                  Indenture; or was nominated for election or elected to such
                  board of directors with the approval of: (a) a majority of the
                  continuing directors who were members of such board at the
                  time of such nomination or election or (b) a nominating
                  committee, a majority of which committee were Continuing

provided, however, that:

                  (1) if at any time the Conversion Rate shall be adjusted
            pursuant to this Indenture, then, on the date and at the time such
            adjustment is so required to be made pursuant hereto, each price set
            forth in the Make-Whole Premium Table above under the column titled
            "Stock Price" shall be deemed to be adjusted so that such price, at
            and after such time, shall be equal to the product of (1) such price
            as in effect immediately before such adjustment to such price and
            (2) a fraction whose numerator is the Conversion Rate in effect
            immediately before such adjustment to the Conversion Rate and whose
            denominator is the Conversion Rate to be in effect, in accordance
            herewith, immediately after such adjustment to the Conversion Rate;

                  (2) if the Stock Price is between two Stock Prices on the
            Make-Whole Premium Table or the Effective Date is between two
            Effective Dates on the Make-Whole Premium Table, the Make-Whole
            Premium shall be determined by straight-line interpolation between
            the Make-Whole Premium amounts set forth for the higher and lower
            Stock Prices and the two Effective Dates, as applicable, based on a
            365-day year;

                  (3) if the Stock Price is equal to or in excess of $25.00 per
            share (subject to adjustment in the same manner as the Stock Price
            as set forth in Section 6.1(b)(iii)(1)) the Make-Whole Premium will
            be as set forth in the bottom row of the table; and

                  (4) if the Stock Price is less than $4.30 per share (subject
            to adjustment in the same manner as the Stock Price as set forth in
            Section 6.1(b)(iii)(1)), the Make-Whole Premium shall be deemed to
            be equal to zero.

      (c) The Make-Whole Premium with respect to a Fundamental Change shall be
paid solely in shares of Common Stock (other than Cash paid in lieu of
fractional shares); provided, however, that if, in connection with such
Fundamental Change, all or substantially all of the shares of Common Stock have
been converted into or exchanged for Cash, other securities or other property,
then such Make-Whole Premium shall be paid in the same form of consideration
into which all or substantially all of the shares of Common Stock have been
converted or exchanged in connection with such Fundamental Change (other than
Cash paid in lieu of fractional interests in any security or pursuant to
dissenters' rights), in accordance herewith; provided, further, that if holders
of the Common Stock receive or have the right to receive more than one form of
consideration in connection with such Fundamental Change, then, for purposes

                                      -38-
<PAGE>

of the immediately preceding proviso, the forms of consideration in which the
Make-Whole Premium shall be paid shall be in proportion to the relative value,
determined in accordance with Section 6.1(d), of the different forms of
consideration paid to holders of Common Stock in connection with such
Fundamental Change; provided further, that, in all cases, any fractional
interests in any security (including Common Stock) or other property
constituting a portion of the Make-Whole Premium payable to a Holder shall be
paid exclusively in Cash (such fractional interest to be valued in accordance
with Section 6.1(d)).

      (d) The value of the shares of Common Stock or other consideration for
purposes of determining the number of shares of Common Stock or other
consideration to be issued or delivered, as the case may be, in respect of a
Make-Whole Premium with respect to a Fundamental Change shall be calculated as
follows:

            (i) in the case such Fundamental Change is a transaction in which
      all or substantially all of the shares of Common Stock have been, as of
      the Effective Date of such Fundamental Change, converted into or exchanged
      for the right to receive securities or other assets or property (including
      Cash), the consideration shall be valued as follows:

                  (1) securities that are traded on the NYSE or other U.S.
            national securities exchange or approved for quotation on Nasdaq or
            any similar system of automated dissemination of quotations of
            securities prices shall be valued at 98% of the average of the
            volume-weighted average prices of such securities (determined in the
            same manner in which the Volume-Weighted Average Price is calculated
            in accordance herewith; provided, however, that if such
            volume-weighted average prices are not available, then the closing
            sales prices of such securities (determined in the same manner in
            which the Closing Sale Price is calculated in accordance herewith)
            on such exchange or system for the five consecutive Trading Days
            beginning on the second Trading Day after the Effective Notice Date
            of such Fundamental Change; provided, however, that the Board of
            Directors shall, in its good faith determination (which
            determination shall be described in a resolution of the Board of
            Directors), make appropriate adjustments to account for any event
            that, assuming such securities were Common Stock, would require,
            pursuant hereto, an adjustment to the Conversion Rate to become
            effective, or any such event whose "ex" date occurs, at any time
            during such five consecutive Trading Days,

                  (2) other securities, assets or property (other than Cash)
            shall be valued at 98% of the average of the fair market value of
            such securities, assets or property (other than Cash) as of the
            close of business on the sixth Trading Day after the Effective
            Notice Date of such Fundamental Change, as determined by two
            independent nationally recognized investment banks selected by the
            Company, and

                  (3) 100% of any Cash.

            (ii) in all other cases, the value of each share of Common Stock
      shall be the average of the Applicable Stock Prices for the five
      consecutive Trading Days

                                      -39-
<PAGE>

      immediately preceding but not including the Effective Date with respect to
      such Fundamental Change (which average shall be appropriately adjusted by
      the Board of Directors, in its good faith determination (which
      determination shall be described in a resolution of the Board of
      Directors), to account for any adjustment, pursuant hereto, to the
      Conversion Rate that shall become effective, or any event requiring,
      pursuant hereto, an adjustment to the Conversion Rate where the "ex" date
      of such event occurs, at any time during such five consecutive Trading
      Days).

      (e) A calculation agent appointed from time to time by the Company (the
"Calculation Agent") shall, on behalf of and on request by the Company,
calculate (A) the Stock Price and (B) the Make-Whole Premium with respect to
such Stock Price, based on the Effective Date specified by the Company, and
shall deliver its calculation of the Stock Price and Make-Whole Premium to the
Company and the Trustee within three Business Days of the request by the Company
or the Trustee. In addition, the Calculation Agent shall, on behalf of and upon
request by the Company or the Trustee, make the determinations described in
Section 6.1(d) above and deliver its calculations to the Company or the Trustee
by 9:00 p.m., New York City time, on the Business Day prior to the applicable
Fundamental Change Purchase Date. The Company or, at the Company's request, the
Trustee, in the name and at the expense of the Company, shall, on the date that
is the seventh Trading Day after the Effective Notice Date with respect to a
Fundamental Change in connection with which a Make-Whole Premium is payable,
mail to each Holder a notice in accordance with Section 16.2, and the Company
shall disseminate on such day a press release, setting forth the Stock Price and
Make-Whole Premium per $1,000 principal amount of Securities (including the
amount and kind of consideration per $1,000 principal amount in which such
Make-Whole Premium is payable) with respect to such Fundamental Change. Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice. The Company shall verify, in writing, to
the Trustee all calculations made by the Calculation Agent pursuant to this
Section 6.1(e). A Calculation Agent shall have the same rights as an Agent to
deal with the Company or an Affiliate of the Company. The Trustee shall not be
responsible for any of the aforementioned calculations and shall be entitled to
rely on an Officers' Certificate with respect to the same.

      (f) Prior to 10:00 a.m., New York City time, on each Fundamental Change
Purchase Date on which a Make-Whole Premium is payable, the Company shall
deposit with the Trustee or with one or more Paying Agents (or, if the Company
or an Affiliate or Subsidiary of the Company is acting as the Paying Agent, set
aside, segregate and hold in trust as provided in Section 2.4) a number of
shares of Common Stock (or other consideration in which such Make-Whole Premium
is payable as herein provided), plus an amount in Cash for fractional interests
in accordance with Section 6.1(c), sufficient to pay the aggregate Make-Whole
Premium due on such Fundamental Change Purchase Date. Payment of the Make-Whole
Premium for Securities surrendered for conversion within the period described in
Section 6.1(a) shall be made promptly on the applicable Fundamental Change
Purchase Date by mailing checks in respect of Cash (or delivering such Cash by
wire transfer if permitted in accordance with Section 9.1) and otherwise
delivering entitlements to securities, other assets or property for the amount
payable to the Holders of such Securities entitled thereto as they shall appear
in the Register.

                                   CONVERSION

Section 7.1. Conversion Privilege.

      Subject to and upon compliance with the provisions of this Article 7 and
paragraph 8 of the Security, at the option of the Holder thereof, any Security,
in whole or in part, may be converted into fully paid and non-assessable Common
Stock at a Conversion Rate (the "Conversion Rate"), initially equivalent to
206.7183 shares of Common Stock per $1,000 principal amount of Securities,
subject to adjustment pursuant to Section 7.6, on or prior to 5:00 p.m., New
York City time, on the Business Day immediately preceding the Final Maturity
Date.

Section 7.2. Conversion Procedure

      (a) The right of conversion attaching to any Security may be exercised at
any time during which conversion is permitted in accordance with Section 7.1 (i)
if such Security is represented by a Global Security, by book-entry transfer to
the Conversion Agent through the facilities of the Depositary in accordance with
the Applicable Procedures, or (ii) if such Security is represented by a
Certificated Security, by delivery of such Security at the specified office of
the Conversion Agent, accompanied, in either case, by: (1) a duly signed and
completed conversion notice, in the form as set forth on the reverse of Security
attached hereto as Exhibit A (a "Conversion Notice"); (2) if such Certificated
Security has been lost, stolen, destroyed or mutilated, a notice to the
Conversion Agent in accordance with Section 2.7 regarding the loss, theft,
destruction or mutilation of the Security; (3) appropriate endorsements and
transfer documents if required by the Conversion Agent; and (4) payment of any
tax or duty, in accordance with Section 7.4, which may be payable in respect of
any transfer involving the issue or delivery of the Common Stock in the name of
a Person other than the Holder of the Security. The date on which the Holder
satisfies all of those requirements is the "Conversion Date." The Company shall
deliver to the Holder through a Conversion Agent a certificate for the number of
whole shares of Common Stock issuable upon the conversion (and Cash in lieu of
any fractional shares pursuant to Section 7.3) as soon as practicable after all
of the requirements for such conversion have been satisfied.

      (b) The person in whose name the Security is registered shall be deemed to
be a stockholder of record on the Conversion Date; provided, however, that no
surrender of a Security or satisfaction of the other conditions in Section
7.2(b) on any date when the stock transfer books of the Company shall be closed
shall be effective to constitute the person or persons entitled to receive the
shares of Common Stock upon such conversion as the record holder or holders of
such shares of Common Stock on such date, but such surrender shall, provided
that all such conditions have been satisfied, be effective to constitute the
person or persons entitled to receive such shares of Common Stock as the record
holder or holders thereof for all purposes at the close of business on the next
succeeding day on which such stock transfer books are open; provided further,
however, that such conversion shall be at the Conversion Rate in effect on the
date on which all such conditions have been satisfied and such Security was
delivered as if the stock transfer books of the Company had not been closed.
Upon conversion of a Security, such person shall no longer be a Holder of such
Security. No separate payment or adjustment will be made

                                      -41-
<PAGE>

for accrued and unpaid interest on a converted Security or for dividends or
distributions on shares of Common Stock issued upon conversion of a Security
except as provided in this Indenture.

      (c) Upon surrender of a Security that is converted in part, the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder, a
new Security equal in principal amount of the unconverted portion of the
Security surrendered.

Section 7.3. Fractional Shares

      The Company will not issue fractional shares of Common Stock upon
conversion of Securities and instead will deliver Cash in an amount equal to the
value of such fraction computed on the basis of the Applicable Stock Price on
the Trading Day immediately before the Conversion Date.

Section 7.4. Taxes on Conversion

      If a Holder converts a Security, the Company shall pay any documentary,
stamp or similar issue or transfer taxes or duties relating to the issuance or
delivery of shares of Common Stock upon exercise of such conversion rights.
However, the Holder shall pay any tax or duty which may be payable relating to
any transfer involving the issuance or delivery of shares of Common Stock in a
name other than the Holder's name. The Conversion Agent may refuse to deliver
the certificate representing shares of Common Stock being issued in a name other
than the Holder's name until the Conversion Agent receives a sum sufficient to
pay any tax or duties which will be due because the shares are to be issued in a
name other than the Holder's name. Nothing herein shall preclude any tax
withholding required by law or regulation.

Section 7.5. Company to Provide Stock

      (a) The Company shall, prior to the issuance of any Securities hereunder,
and from time to time as may be necessary, reserve at all times and keep
available, free from preemptive rights, out of its authorized but unissued
Common Stock, a sufficient number of shares of Common Stock deliverable upon
conversion of all of the Securities.

      (b) All shares of Common Stock that may be issued upon conversion of the
Securities shall be newly issued shares or shares held in the treasury of the
Company, shall be duly authorized, validly issued, fully paid and nonassessable
and shall be free of any preemptive rights and free of any lien or adverse
claim.

      (c) The Company shall comply with all applicable securities laws
regulating the offer and delivery of any Common Stock upon conversion of
Securities and shall list or cause to have quoted such shares of Common Stock on
the NYSE or any United States national or regional securities exchange or on
Nasdaq or such other market on which the Common Stock is then listed or quoted;
provided, however, that, if the rules of such automated quotation system or
exchange permit the Company to defer the listing of such Common Stock until the
first conversion of the Securities into Common Stock in accordance with the
provisions of this Indenture, the Company covenants to list such Common Stock
issuable upon conversion of the

                                      -42-
<PAGE>

Securities in accordance with the requirements of such automated quotation
system or exchange at such time.

      (d) Notwithstanding anything herein to the contrary, nothing herein shall
give to any Holder any rights as a creditor in respect solely of its right to
conversion.

Section 7.6. Adjustment of Conversion Rate

      The Conversion Rate shall be adjusted from time to time by the Company as
follows:

      (a) In case the Company shall (i) issue shares of its Common Stock as a
dividend or distribution on its Common Stock or (ii) subdivide, combine or
reclassify its outstanding Common Stock, the Conversion Rate in effect
immediately prior thereto shall be adjusted so that the Holder of any Security
thereafter surrendered for conversion shall be entitled to receive that number
of shares of Common Stock which it would have been entitled to (without giving
effect to any arrangement pursuant to such dividend, distribution, subdivision,
combination or reclassification not to issue fractional shares of Common Stock)
had such Security been converted immediately prior to the record date of such
event or the happening of such event. An adjustment made pursuant to this
subsection (a) shall become effective immediately after the record date in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision, combination or
reclassification.

      (b) In case the Company shall issue rights or warrants to all holders of
its Common Stock entitling them to subscribe for or purchase shares of Common
Stock at a price per share less than the Current Market Price per share (as
determined in accordance with subsection (f) of this Section 7.6) of Common
Stock on the record date for such issuance (other than a distribution of rights
pursuant to the Existing Rights Plan), the Conversion Rate in effect immediately
prior to the close of business on the record date for the issuance shall be
increased by multiplying the Conversion Rate in effect immediately prior to the
close of business on such record date by a fraction of which (A) the numerator
shall be the sum of (I) the number of shares of Common Stock outstanding
(excluding shares held in the treasury of the Company) at the close of business
on such record date and (II) the aggregate number of shares (the "Underlying
Shares") of Common Stock underlying all such issued rights or warrants (whether
by exercise, conversion, exchange or otherwise) and (B) the denominator shall be
the sum of (I) number of shares of Common Stock outstanding (excluding shares
held in the treasury of the Company) at the close of business on such record
date and (II) the number of shares of Common Stock which the aggregate exercise,
conversion, exchange or other price at which the Underlying Shares may be
subscribed for or purchased pursuant to such rights or warrants would purchase
at such Current Market Price per share of Common Stock. Such increase shall
become effective immediately prior to the opening of business on the Business
Day following such record date. In no event shall the Conversion Rate be
decreased pursuant to this Section 7.6(b). Notwithstanding the preceding
sentence, the Conversion Rate will be adjusted in accordance with this Section
7.6(b) to the extent that such rights or warrants are not exercised prior to
their expiration.

      (c) In case the Company shall distribute to all holders of its Common
Stock any shares of capital stock of the Company, evidences of indebtedness or
other non-Cash assets, or rights or warrants (excluding (i) dividends,
distributions and rights or warrants referred to in

                                      -43-
<PAGE>

subsection (a) or (b) of this Section 7.6, (ii) distributions referred to in
subsection (e) of this Section 7.6 and (iii) the distribution of rights pursuant
to a shareholder rights plan (including the Existing Rights Plan) for which
provision has been made in accordance with the third paragraph of this Section
7.6(c)), the Conversion Rate shall be increased by multiplying the Conversion
Rate in effect immediately prior to the close of business on the record date for
the distribution by a fraction of which (A) the numerator shall be the Current
Market Price per share (as defined in subsection (f) of this Section 7.6)) of
the Common Stock on such record date and (B) the denominator shall be an amount
equal to (I) such Current Market Price per share less (II) the fair market value
on such record date (as determined by the Board of Directors, whose
determination shall be conclusive evidence of such fair market value and which
shall be evidenced by an Officers' Certificate delivered to the Trustee) of the
portion of the capital stock, evidences of indebtedness or other non-Cash assets
so distributed or of such rights or warrants applicable to one share of Common
Stock (determined on the basis of the number of shares of Common Stock
outstanding at the close of business on the record date); provided, however,
that, in the event the then fair market value (as so determined) of the portion
of the capital stock, evidences of indebtedness or other non-Cash assets so
distributed or of such rights or warrants applicable to one share of Common
Stock is equal to or greater than the Current Market Price per share of the
Common Stock on such record date, then, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Holder shall have the right to
receive upon conversion (in addition to any other consideration payable
hereunder upon conversion) the amount of capital stock, evidences of
indebtedness or other non-Cash assets so distributed or of such rights or
warrants such holder would have received had such holder converted each Security
on such record date. In no event shall the Conversion Rate be decreased pursuant
to this Section 7.6(c). Such adjustment (if any) shall be made successively
whenever any such distribution is made and shall become effective immediately
after such record date.

      In the event that such dividend or distribution is not so paid or made,
the Conversion Rate shall again be adjusted to be the Conversion Rate which
would then be in effect if such dividend or distribution had not been declared.
If the Board of Directors of the Company determines the fair market value of any
distribution for purposes of this Section 7.6(c) by reference to the actual or
when issued trading market for any securities, it must in doing so consider the
prices in such market over the same period used in computing the applicable
Current Market Price per share of Common Stock.

      The Company shall make adequate provisions such that, upon conversion of
the Securities into Common Stock, to the extent that the Existing Rights Plan or
any new shareholder rights plan (i.e. poison pill) hereafter implemented by the
Company is in effect upon such conversion, the Holders of Securities will
receive, in addition to the Common Stock and other consideration payable
hereunder upon conversion, the rights described in such Existing Rights Plan or
new rights plan (whether or not the rights have separated from the Common Stock
at the time of conversion), subject to the limitations set forth in such
Existing Rights Plan or new rights plan. Any distribution of rights or warrants
pursuant to such Existing Rights Plan or new rights plan complying with the
requirements set forth in the immediately preceding sentence of this paragraph
shall not constitute a distribution of rights or warrants pursuant to this
Section 7.6(c).

                                      -44-
<PAGE>

      (d) In case the Company shall dividend or distribute (other than in
connection with a liquidation, dissolution or winding up of the Company) Cash (a
"Cash Dividend") to all holders of Common Stock (other than a distribution
requiring an adjustment to the Conversion Rate pursuant to Section 7.6(e)), the
Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the close of business on the record date for the
determination of holders of Common Stock entitled to such dividend or
distribution by a fraction (A) whose numerator shall be the average of the
Volume-Weighted Average Prices per share of Common Stock (or, if such
Volume-Weighted Average Prices are not available, the Closing Sale Prices) for
the five consecutive Trading Days ending on the date immediately preceding the
"ex" date (as defined in Section 7.6(f)) for such Cash Dividend or distribution
(which average shall be appropriately adjusted by the Board of Directors, in its
good faith determination (which determination shall be described in a resolution
of the Board of Directors), to account for any adjustment, pursuant hereto, to
the Conversion Rate that shall become effective, or any event requiring,
pursuant hereto, an adjustment to the Conversion Rate where the "ex" date of
such event occurs, at any time during such five consecutive Trading Days); and
(B) whose denominator shall be an amount equal to (I) such average
Volume-Weighted Average Price (or, if applicable, average Closing Sale Price)
per share of Common Stock less (II) the amount per share of Common Stock of such
Cash Dividend or distribution. An adjustment to the Conversion Rate pursuant to
this Section 7.6(d) shall become effective immediately prior to the opening of
business on the Business Day immediately following such record date. In no event
shall the Conversion Rate be decreased pursuant to this Section 7.6(d).

      (e) In case the Company or any Subsidiary of the Company shall distribute
Cash or other consideration in respect of a tender offer or exchange offer made
by the Company or any Subsidiary of the Company for all or any portion of the
Common Stock where the sum of the aggregate amount of such Cash distributed and
the aggregate fair market value (as determined in good faith by the Board of
Directors, whose determination shall be conclusive and set forth in a resolution
of the Board of Directors), as of the Expiration Date (as defined below), of
such other consideration distributed (such sum, the "Aggregate Amount")
expressed as an amount per share of Common Stock validly tendered or exchanged,
and not withdrawn, pursuant to such tender offer or exchange offer as of the
Expiration Time (as defined below) (such tendered or exchanged shares of Common
Stock, the "Purchased Shares") exceeds the Current Market Price per share (as
determined in accordance with subsection (f) of this Section 7.6) of Common
Stock on the last date (such last date, the "Expiration Date") on which tenders
or exchanges could have been made pursuant to such tender offer or exchange
offer (as the same may be amended through the Expiration Date), then the
Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the close of business on the Expiration Date by a fraction
(A) whose numerator is equal to the sum of (I) the Aggregate Amount and (II) the
product of (a) the Current Market Price per share of Common Stock (as determined
in accordance with subsection (f) of this Section 7.6) on the Expiration Date
and (b) an amount equal to the number of shares of Common Stock outstanding as
of the last time (the "Expiration Time") at which tenders or exchanges could
have been made pursuant to such tender offer or exchange offer (excluding
Purchased Shares and shares held at such time in the treasury of the Company)
and (B) whose denominator is equal to the product of (I) the number of shares of
Common Stock outstanding as of the Expiration Time (including all Purchased
Shares but excluding shares held at such time in the treasury of the Company)
and (II) such Current Market Price per share of

                                      -45-
<PAGE>

Common Stock on the Expiration Date. An increase, if any, to the Conversion Rate
pursuant to this Section 7.6(e) shall become effective immediately prior to the
opening of business on the Business Day following the Expiration Date. In the
event that the Company or a Subsidiary of the Company is obligated to purchase
shares of Common Stock pursuant to any such tender offer or exchange offer, but
the Company or such Subsidiary is permanently prevented by applicable law from
effecting any such purchases, or all such purchases are rescinded, then the
Conversion Rate shall again be adjusted to be the Conversion Rate which would
then be in effect if such tender offer or exchange offer had not been made. If
the application of this Section 7.6(e) to any tender offer or exchange offer
would result in a decrease in the Conversion Rate, no adjustment shall be made
for such tender offer or exchange offer under this Section 7.6(e).

      (f) For the purpose of making a computation pursuant to this Section 7.6,
the current market price (the "Current Market Price") on a date of determination
shall mean the average of the Closing Sale Prices per share of Common Stock for
the five consecutive Trading Days ending on the date of determination; provided,
however, that such Current Market Price shall be appropriately adjusted by the
Board of Directors, in its good faith determination (which determination shall
be described in a resolution of the Board of Directors), to account for any
adjustment pursuant hereto (other than the adjustment requiring such
computation) to the Conversion Rate that shall become effective, or any event
(other than the event requiring such computation) requiring, pursuant hereto, an
adjustment to the Conversion Rate where the "ex" date of such event occurs, at
any time during such five consecutive Trading Days. For purposes hereof, the
term "ex" date means (i) when used with respect to any dividend or distribution,
the first date on which the Common Stock trades, regular way, on the relevant
exchange or in the relevant market from which the Closing Sale Price was
obtained without the right to receive such dividend or distribution; and (ii)
when used with respect to any tender offer or exchange offer, the first date on
which the Common Stock trades, regular way, on the relevant exchange or in the
relevant market from which the Closing Sale Price was obtained after the
expiration time of such tender offer or exchange offer (as it may be amended or
extended).

      (g) In any case in which this Section 7.6 shall require that an adjustment
be made following a record date or Expiration Date, as the case may be,
established for purposes of this Section 7.6, the Company may elect to defer
(but only until five Business Days following the filing by the Company with the
Trustee of the certificate described in Section 7.9) issuing to the Holder of
any Security converted after such record date or Expiration Date the shares of
Common Stock and other capital stock of the Company, evidences of indebtedness
or other non-Cash assets or rights or warrants issuable upon such conversion
over and above the shares of Common Stock and other capital stock of the
Company, evidences of indebtedness or other non-Cash assets or rights or
warrants issuable, or Cash payable, upon such conversion only on the basis of
the Conversion Rate prior to adjustment; and, in lieu of the shares, evidences
of indebtedness or other non-Cash assets or rights or warrants the issuance of
which, or Cash the payment of which, is so deferred, the Company shall issue or
cause its transfer agents to issue due bills or other appropriate evidence
prepared by the Company of the right to receive such shares or Cash, as the case
may be. If any distribution in respect of which an adjustment to the Conversion
Rate is required to be made as of the record date or Expiration Date therefor is
not thereafter made or paid by the Company for any reason, the Conversion Rate
shall be readjusted

                                      -46-
<PAGE>

to the Conversion Rate which would then be in effect if such record date had not
been fixed or such effective date or Expiration Date had not occurred.

Section 7.7. No Adjustment

      No adjustment in the Conversion Rate shall be required unless the
adjustment would result in a change in the Conversion Rate of at least 1%;
provided, however, that any adjustment which by reason of this Section 7.7 is
not required to be made shall be carried forward and taken into account in
subsequent adjustments. All calculations under this Article 7 shall be made to
the nearest one-thousandth of a cent or to the nearest one-thousandth of a
share, as the case may be.

      Except as otherwise provided for in this Indenture, the Company shall not
be required to adjust the Conversion Rate for the issuance of its Common Stock
or any securities convertible or exchangeable for its Common Stock or the right
to purchase its Common Stock or such convertible or exchangeable securities.

      No adjustment need be made for (i) issuances of Common Stock pursuant to a
Company plan for reinvestment of dividends or interest or the investment of
additional optional amounts thereunder in shares of Common Stock or for a change
in the par value or a change to no par value of the Common Stock or (ii) upon
the issuance of any shares of Common Stock or options or rights to purchase
shares of Common Stock pursuant to any present or future employee, director or
consultant benefit plan or program of or assumed by the Company or any of its
subsidiaries.

      To the extent that the Securities become convertible into the right to
receive Cash, interest will not accrue on such Cash.

      No adjustment to the Conversion Rate need be made pursuant to Section 7.6
for a transaction if Holders are to participate in the transaction without
conversion on a basis and with notice that the Board of Directors of the Company
determines in good faith to be fair and appropriate in light of the basis and
notice on which holders of Common Stock participate in the transaction.

      No adjustment to the Conversion Rate need be made upon the issuance of any
shares of Common Stock pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security outstanding as of the date the Securities
were first issued.

      No adjustment to the Conversion Rate need be made for accrued and unpaid
interest, including additional interest, if any.

Section 7.8. Other Adjustments

      Subject to applicable stock exchange rules and listing standards, the
Company shall be entitled to increase the Conversion Rate by any amount for a
period of at least 20 days if the Company's Board of Directors determines that
such increase would be in the best interests in the Company, provided the
Company has given to holders at least 15 days' prior notice, in accordance with
Section 16.2, of any such increase in the Conversion Rate. Subject to applicable

                                      -47-
<PAGE>

stock exchange rules and listing standards, the Company shall be entitled to
increase the Conversion Rate, in addition to the events requiring an increase in
the Conversion Rate pursuant to Section 7.6, as it in its discretion shall
determine to be advisable in order to avoid or diminish any tax to stockholders
in connection with any stock dividends, subdivisions of shares, distributions of
rights to purchase stock or securities or distributions of securities
convertible into or exchangeable for stock hereafter made by the Company to its
stockholders.

Section 7.9. Notice of Adjustment

      Whenever the Conversion Rate or conversion privilege is adjusted, the
Company shall promptly mail to Securityholders a notice of the adjustment in
accordance with Section 16.2, and file with the Trustee an Officers' Certificate
briefly stating the facts requiring the adjustment and the manner of computing
it. Unless and until the Trustee shall receive an Officers' Certificate setting
forth an adjustment of the Conversion Rate, the Trustee may assume without
inquiry that the Conversion Rate has not been adjusted and that the last
Conversion Rate of which it has knowledge remains in effect.

Section 7.10. Limitation on Conversions.

      Notwithstanding any other provision of this Article 7, no Initial
Purchaser and no Affiliate of any such Initial Purchaser or other person acting
on behalf of such Initial Purchaser (a "Purchaser Affiliate"), may convert any
Securities (whether or not acquired directly from the Company), if the number of
shares of Common Stock that would be received by such Initial Purchaser or
Purchaser Affiliate, when aggregated with all other shares of Common Stock
previously acquired upon conversion of any Securities by such Initial Purchaser
and its Purchaser Affiliates as a group (whether or not such previously-acquired
shares are still held by such Initial Purchaser or a Purchaser Affiliate), would
exceed 1,280,652 shares. Any Holder who submits a Conversion Notice shall be
deemed to certify that the conversion contemplated by such Conversion Notice is
not prohibited by the provisions of this Section 7.10 and that it was in
compliance with such provisions.

Section 7.11. Effect of Reclassification, Consolidation, Merger or Sale on
              Conversion Privilege

      If (1) there shall occur (a) any reclassification of the Common Stock
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination); (b) a
statutory share exchange, consolidation, merger or combination involving the
Company other than a merger in which the Company is the continuing corporation
and which does not result in any reclassification of, or change (other than in
par value, or from par value to no par value, or from no par value to par value,
or as a result of a subdivision or combination) in, outstanding shares of Common
Stock; or (c) a sale or conveyance as an entirety or substantially as an
entirety of the property and assets of the Company, directly or indirectly, to
another Person; and (2) pursuant to such reclassification, statutory share
exchange, consolidation, merger, combination, sale or conveyance, holders of
outstanding shares of Common Stock would be entitled to receive stock (other
than Common Stock), other securities, other property, assets or Cash for such
shares of Common Stock, then the Company, or such successor or surviving,
purchasing or transferee Person, as the case may be, shall, as a condition
precedent to such reclassification, statutory share exchange,

                                      -48-
<PAGE>

consolidation, merger, combination, sale or conveyance, execute and deliver to
the Trustee a supplemental indenture providing that, at and after the effective
time of such reclassification, statutory share exchange, consolidation, merger,
combination, sale or conveyance, the Holder of each Security then outstanding
shall have the right to convert such Security into the kind and amount of shares
of stock and other securities and property (including Cash) receivable upon such
reclassification, statutory share exchange, consolidation, merger, combination,
sale or conveyance by a holder of the number of shares of Common Stock
deliverable upon conversion of such Security immediately prior to such
reclassification, statutory share exchange, consolidation, merger, combination,
sale or conveyance, assuming that such Holder would not have exercised any
rights of election that such Holder would have had as a holder of Common Stock
to select a particular type of consideration. Such supplemental indenture shall
provide for adjustments of the Conversion Rate which shall be as nearly
equivalent as may be practicable to the adjustments of the Conversion Rate
provided for in this Article 7. If, in the case of any such reclassification,
statutory share exchange, consolidation, merger, combination, sale or
conveyance, the stock or other securities and property (including Cash)
receivable thereupon by a holder of Common Stock include shares of stock or
other securities and property of a Person other than the successor or surviving,
purchasing or transferee Person, as the case may be, in such reclassification,
statutory share exchange, consolidation, merger, combination, sale or
conveyance, then such supplemental indenture shall also be executed by such
other Person and shall contain such additional provisions to protect the
interests of the Holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
provisions of this Section 7.11 shall similarly apply to successive
reclassifications, statutory share exchanges, consolidations, mergers,
combinations, sales and conveyances. The foregoing, however, shall not in any
way affect the right a Holder of a Security may otherwise have pursuant to
Section 7.6(c) to receive rights and warrants in accordance therewith.

      In the event the Company shall execute a supplemental indenture pursuant
to this Section 7.11, the Company shall promptly file with the Trustee (x) an
Officers' Certificate briefly stating the reasons therefor, the kind or amount
of shares of stock or other securities or property (including Cash) receivable
by Holders of the Securities upon the conversion of their Securities after any
such reclassification, statutory share exchange, consolidation, merger,
combination, sale or conveyance, any adjustment to be made with respect thereto
and that all conditions precedent have been satisfied and (y) an Opinion of
Counsel that all conditions precedent have been satisfied, and shall promptly
mail notice thereof to all Holders.

Section 7.12. Trustee's Disclaimer

      The Trustee shall have no duty to determine when an adjustment under this
Article 7 should be made, how it should be made or what such adjustment should
be, but may accept as conclusive evidence of that fact or the correctness of any
such adjustment set forth in, and shall be protected in relying upon, an
Officers' Certificate, including the Officers' Certificate with respect thereto
which the Company is obligated to file with the Trustee pursuant to Section 7.9.
The Trustee makes no representation as to the validity or value of any
securities or assets issued upon conversion of Securities, and the Trustee shall
not be responsible for the Company's failure to comply with any provisions of
this Article 7.

                                      -49-
<PAGE>

      The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 7.11, but may accept as conclusive evidence of the
correctness thereof, and shall be fully protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 7.11.

Section 7.13. [Reserved].

Section 7.14. Effect of Conversion; Conversion After Record Date

      Except as provided in this Section 7.14, a converting Holder of Securities
shall not be entitled to receive any separate Cash payments with respect to
accrued and unpaid interest on any such Securities being converted. By delivery
to the Holder of the number of shares of Common Stock or other consideration
issuable or Cash payable upon conversion in accordance with this Article 7, the
Company will have satisfied its obligations with respect to the Securities and
any accrued and unpaid interest on such Securities will not be paid. If any
Securities are converted after the close of business on an Interest Payment
Record Date but prior to the corresponding Interest Payment Date, the Holder of
such Securities as of the close of business on such Interest Payment Record Date
shall receive, on such Interest Payment Date, the interest payable on such
Security on such Interest Payment Date notwithstanding the conversion thereof;
provided, however, each Security surrendered for conversion after the close of
business on an Interest Payment Record Date but prior to the corresponding
Interest Payment Date shall be accompanied by payment from the converting Holder
thereof, for the account of the Company, in Cash, an amount equal to the
interest payable on such Security on such Interest Payment Date; provided
further that no such payment need be made if (a) the Company has specified a
Redemption Date that is after the close of business on an Interest Payment
Record Date but on or prior to the corresponding Interest Payment Date or that
results in conversion prior to that Interest Payment Date, (b) any overdue
interest exists at the time of conversion with respect to such Security, but
only to the extent of the amount of such overdue interest or (c) the Holder
surrenders any Securities for conversion after the close of business on the
Interest Payment Record Date relating to the final Interest Payment Date.

      Except as otherwise provided in this Indenture, no payment or adjustments
in respect of payments of interest on Securities surrendered for conversion or
any dividends or distributions on the Common Stock issued upon conversion shall
be made upon the conversion of any Securities.

                                    ARTICLE 8

                              SUBSIDIARY GUARANTEE

Section 8.1. Subsidiary Guarantors

      If any Subsidiary of the Company shall guarantee any obligation of the
Company evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses by the Company (other than the Existing Credit Facility,
(each such obligation a "Debt Security") the Company

                                      -50-
<PAGE>

shall (i) cause each of (1) such Subsidiary and (2) any Subsidiary to which the
Company has transferred all or substantially all of its assets concurrently to
become a Subsidiary Guarantor by executing and delivering to the Trustee a
supplemental indenture pursuant to which such Subsidiary shall unconditionally
guarantee (a "Subsidiary Guarantee") all of the Company's obligations under the
Securities and this Indenture on a senior unsecured basis, on terms
substantially consistent with guarantees of substantially similar debt
obligations, to the same extent as the Subsidiary referred to above in (1)
guaranteed such other Debt Securities and (ii) cause an Opinion of Counsel to be
delivered to the Trustee to the effect that such supplemental indenture has been
duly authorized and executed by each such Person and constitutes the valid,
binding and enforceable obligation of each such Person (subject to customary
exceptions concerning creditors' rights and equitable principles).

      Such supplemental indenture shall be executed by manual signature on
behalf of each respective Subsidiary Guarantor by any one of such Subsidiary
Guarantor's Chairman of the Board of Directors, Vice Chairman of the Board of
Directors, Chief Executive Officer, President or Chief Financial Officer or Vice
Presidents, attested by its Secretary or Assistant Secretary.

      Such supplemental indenture bearing the manual signatures of individuals
who were at any time the proper officers of a Subsidiary Guarantor shall bind
such Subsidiary Guarantor, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the execution and delivery of the
supplemental indenture or did not hold such offices at the date of such
supplemental indenture.

Section 8.2. Subsidiary Guarantors May Consolidate, Etc., on Certain Terms

      Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of any Subsidiary Guarantor with or into the
Company or any other Subsidiary Guarantor or shall prevent any sale or
conveyance of the property of any Subsidiary Guarantor as an entirety or
substantially as an entirety to the Company or any other Subsidiary Guarantor.

Section 8.3. Release of Subsidiary Guarantors

      If (i) subject to Article 10 hereof, any sale or other disposition of all
or substantially all of the assets of any Subsidiary Guarantor occurs (by way of
merger, consolidation or otherwise) or a sale or other disposition of all of the
Capital Stock of any Subsidiary Guarantor, in each case to a Person that is not
(either before or after giving effect to such transactions) the Company or a
Subsidiary of the Company, (ii) in the case of a Subsidiary referred to in
Section 8.1(i)(1) hereof, such Subsidiary is no longer a guarantor of any Debt
Securities, or (iii) in the case of a Subsidiary referred to in Section
8.1(i)(2) hereof, no Subsidiary of the Company is a guarantor of any Debt
Securities, and, in any such case, if the Company shall deliver to the Trustee
an Officers' Certificate certifying to that effect as of the date of such
Officers' Certificate, then automatically, without the requirement of any
further action by the Company, such Subsidiary or the Trustee, such Subsidiary
shall cease to be a Subsidiary Guarantor hereunder and such Subsidiary or, as
applicable in the case of clause (i) above, the acquiring Person shall have no
continuing obligation or liability under its Subsidiary Guarantee. The Trustee
shall, at the

                                      -51-
<PAGE>

Company's expense, execute and deliver such instruments as the Company may
reasonably request to evidence such termination.

      (a) Notwithstanding that the Company may not be required to be or remain
subject to the reporting requirements of Section 13 or 15(d) of the Exchange

within the time periods specified by the SEC. The Company shall file with the

would prohibit or forgive the Company from paying all or any portion of the
principal amount, Redemption Price or Put Price in respect of Securities, or any
interest on the Securities as contemplated herein, wherever enacted, now or at
any time hereafter in force, or which may affect the covenants or the
performance of this Indenture, and the Company, to the extent it may lawfully do

Section 10.1. Company May Consolidate, Etc., Only on Certain Terms

      The Company shall not consolidate with or merge into any other Person (in
a transaction in which the Company is not the surviving Person) or convey,
transfer or lease all or substantially all of the Company's properties and
assets to any successor Person, unless:

            consolidation, merger, conveyance, transfer or lease and, if a

      Notwithstanding the foregoing, the Company may transfer all or
substantially all of its assets to a wholly-owned Subsidiary without such

                              DEFAULT AND REMEDIES

Section 11.1. Events of Default

      An "Event of Default" shall occur if:

                  (1) the Company defaults in the payment of any principal of
            any of the Securities when the same becomes due and payable (whether
            at maturity, upon Redemption, on a Put Purchase Date or otherwise);

                  (2) the Company defaults in the payment of any accrued and
            unpaid interest (including Additional Interest, if any, and any
            Make-Whole Premium) when due and payable, and such default continues
            for a period of 30 days;

                  (3) the Company fails to satisfy its conversion obligations
            upon exercise of a Holder's conversion rights pursuant hereto;

                  (4) the Company fails to provide the Fundamental Change
            Company Notice when required by this Indenture;

                  (5) the Company fails to comply with any of its other
            agreements contained in the Securities or in this Indenture (other
            than those referred to in

                                      -55-
<PAGE>

            clauses 1 through 4 above or clause 9 below) and such failure
            continues for 60 days after receipt by the Company of a Notice of
            Default;

                  (6) the Company or any Significant Subsidiary fails to make
            any payment of principal in excess of $10,000,000 in respect of
            indebtedness for borrowed money, when and as the same shall become
            due and payable, whether at maturity or upon acceleration, and such
            indebtedness is not paid, or such acceleration is not rescinded, by
            the end of the 30th day after receipt by the Company or such
            Significant Subsidiary of a Notice of Default;

                  (7) the Company, or any other Significant Subsidiary pursuant
            to or within the meaning of any Bankruptcy Law:

                  (A) commences a voluntary case or proceeding;

                  (B) consents to the entry of an order for relief against it in
            an involuntary case or proceeding or the commencement of any case
            against it;

                  (C) consents to the appointment of a Custodian of it or for
            any substantial part of its property; or

                  (D) makes a general assignment for the benefit of its
            creditors; or

                  (8) a court of competent jurisdiction enters an order or
            decree under any Bankruptcy Law that:

                  (A) is for relief against the Company or a Significant
            Subsidiary in an involuntary case or proceeding;

                  (B) appoints a Custodian of the Company or a Significant
            Subsidiary for any substantial part of the property of the Company
            or such Significant Subsidiary; or

                  (C) orders the winding up or liquidation of the Company or a
            Significant Subsidiary;

      and in each case of this subclause (8) the order or decree remains
      unstayed and in effect for 60 consecutive days.

            The term "Bankruptcy Law" means Title 11 of the United States Code
      (or any successor thereto) or any similar federal or state law for the
      relief of debtors. The term "Custodian" means any receiver, trustee,
      assignee, liquidator, sequestrator or similar official under any
      Bankruptcy Law.

                  (9) The Company fails to perform or comply with Article 8
            hereof, or any Subsidiary Guarantee ceases to be in full force and
            effect (other than in accordance with the terms of this Indenture)
            or is declared to be null and void and unenforceable or the
            Subsidiary Guarantee is found to be invalid or a Subsidiary

                                      -56-
<PAGE>

            Guarantor that is a Significant Subsidiary denies its liability
            under its Subsidiary Guarantee (other than by reason of release of
            the Subsidiary Guarantor in accordance with the terms of this
            Indenture).

      A default under clause (5) or (6) above is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities then outstanding notify the Company and the
Trustee, in writing of the Default, and the Company does not cure the Default
(and such Default is not waived) within the time period specified in clauses (5)
or (6) above, as applicable, after actual receipt of such notice. The notice
given pursuant to this Section 11.1 must specify the Default, demand that it be
remedied and state that the notice is a "Notice of Default." When any Default
under this Section 11.1 is cured in accordance herewith, it shall cease to be a
Default.

      The Trustee shall not be charged with knowledge of any Event of Default
unless written notice thereof shall have been given to a Trust Officer at the
Corporate Trust Office of the Trustee by the Company (including, without
limitation, pursuant to Section 9.3), a Paying Agent, any Holder or any agent of
any Holder.

Section 11.2. Acceleration

      If an Event of Default (other than an Event of Default with respect to the
Company specified in clause (7) or (8) of Section 11.1) occurs and is
continuing, the Trustee may, by notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the Securities then outstanding may,
by notice to the Company and the Trustee, declare all unpaid principal of plus
interest (including Additional Interest, if any) accrued and unpaid through the
date of such declaration on all the Securities then outstanding to be due and
payable upon any such declaration, and the same shall thereupon become and be
immediately due and payable.

      If an Event of Default with respect to the Company specified in clause (7)
or (8) of Section 11.1 occurs, all unpaid principal of plus accrued and unpaid
interest (including Additional Interest, if any) on all the Securities then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

      The Holders of a majority in aggregate principal amount of the Securities
then outstanding or the Holders originally causing the acceleration by notice to
the Trustee may rescind an acceleration of Securities and its consequences
before a judgment or decree for the payment of money has been obtained by the
Trustee if (a) the rescission would not conflict with any existing order or
decree, (b) all existing Events of Default, other than the nonpayment of the
principal of plus accrued and unpaid interest on the Securities that has become
due solely by such declaration of acceleration, have been cured or waived and
(c) all payments due to the Trustee and any predecessor Trustee under Section
12.6 have been made. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

                                      -57-
<PAGE>

Section 11.3. Other Remedies

      If an Event of Default occurs and is continuing, the Trustee may, but
shall not be obligated to, pursue any available remedy by proceeding at law or
in equity to collect the payment of the principal of or accrued and unpaid
interest on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

      The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

Section 11.4. Waiver of Defaults and Events of Default

      Subject to Sections 11.7 and 13.2, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by notice to the Trustee may
waive an existing Default or Event of Default and its consequence, except a
Default or Event of Default in the payment of the principal of, or any interest
(including Additional Interest, if any) on any Security, or the payment of any
applicable Fundamental Change Purchase Price or Redemption Price, or a failure
by the Company to convert any Securities in accordance with Article 7 or any
Default or Event of Default in respect of any provision of this Indenture or the
Securities that, under Section 13.2, cannot be modified or amended without the
consent of the Holders of each outstanding Security. When a Default or Event of
Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right. This Section 11.4
shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section
316(a)(1)(B) is hereby expressly excluded from this Indenture, as permitted by
the TIA.

Section 11.5. Control by Majority

      The Holders of a majority in aggregate principal amount of the Securities
then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it under this Indenture. However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, that the Trustee
determines may be unduly prejudicial to the rights of another Holder or the
Trustee, or that may involve the Trustee in personal liability unless the
Trustee is offered security or indemnity reasonably satisfactory to it; provided
that the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction; provided further that this provision shall
not affect the rights of the Trustee set forth in Section 12.1(b)(v). This
Section 11.5 shall be in lieu of Section 316(a)(1)(A) of the TIA and such
Section 316(a)(1)(A) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

Section 11.6. Limitations on Suits

      Subject to Section 11.7, a Holder of a Security may not pursue any remedy
with respect to this Indenture or the Securities unless:

                                      -58-
<PAGE>

                  (1) the Holder gives to the Trustee written notice of a
            continuing Event of Default;

                  (2) the Holders of at least 25% in aggregate principal amount
            of the then outstanding Securities make a written request to the
            Trustee to pursue the remedy;

                  (3) such Holder or Holders offer to the Trustee security or
            indemnity reasonably satisfactory to the Trustee against any loss,
            liability or expense;

                  (4) the Trustee does not comply with the request within 60
            days after receipt of the notice, request and the offer of security
            or indemnity; and

                  (5) no direction inconsistent with such written request has
            been given to the Trustee during such 60-day period by the Holders
            of a majority in aggregate principal amount of the Securities then
            outstanding.

      A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over such other
Securityholder.

Section 11.7. Rights of Holders to Receive Payment and to Convert

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of the principal amount, Redemption
Price, Fundamental Change Purchase Price or interest (including Additional
Interest, if any) on any Security, on or after the respective due dates
expressed in the Security and this Indenture, to convert such Security in
accordance with Article 7 and to bring suit for the enforcement of any such
payment on or after such respective dates or the right to convert, is absolute
and unconditional and shall not be impaired or affected without the consent of
the Holder.

Section 11.8. Collection Suit by Trustee

      If an Event of Default in the payment of principal or interest specified
in clause (1) or (2) of Section 11.1 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or another obligor on the Securities for the whole amount owing with
respect to the Securities and the amounts provided for in Section 12.6.

Section 11.9. Trustee May File Proofs of Claim

      The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Holders allowed in
any judicial proceedings relative to the Company (or any other obligor on the
Securities), its creditors or its property and shall be entitled and empowered
to collect and receive any money or other property payable or deliverable on any
such claims and to distribute the same, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent

                                      -59-
<PAGE>

to the making of such payments directly to the Holders, to pay to the Trustee
any amount due to it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 12.6, and to the extent that such payment of the
reasonable compensation, expenses, disbursements and advances in any such
proceedings shall be denied for any reason, payment of the same shall be secured
by a lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other property which the Holders may be entitled to
receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or, on behalf of any
Holder, to authorize, accept or adopt any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

Section 11.10. Priorities

      Any money or property collected by the Trustee pursuant to this Article
11, and after an Event of Default, any money or other property distributable in
respect of the Company's obligations under this Indenture shall be paid out in
the following order:

            First, to the Trustee (including any predecessor Trustee) for
      amounts due under Section 12.6;

            Second, to Securityholders for amounts due and unpaid on the
      Securities for the principal amount, Redemption Price, Fundamental Change
      Purchase Price or interest (including Additional Interest, if any) or
      Make-Whole Premium, if any, as the case may be, ratably, without
      preference or priority of any kind, according to such amounts due and
      payable on the Securities; and

            Third, the balance, if any, to the Company.

      The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 11.10. At least 15 days before such record
date, the Trustee shall mail to each Holder and the Company a notice that states
the record date, the payment date and the amount to be paid.

Section 11.11. Undertaking for Costs

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 11.11 does not apply to a suit made by the Trustee, a
suit by a Holder pursuant to Section 11.7, or a suit by Holders of more than 25%
in aggregate principal amount of the Securities then outstanding. This Section
11.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is
hereby expressly excluded from this Indenture, as permitted by the TIA.

                                      -60-
<PAGE>

Section 11.12. Delay or Omission Not Waiver

      No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article 11 or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

                                     TRUSTEE

Section 12.1. Certain Duties and Responsibilities of Trustee

      (a) The Trustee, prior to the occurrence of an Event of Default with
respect to the Securities and after the curing or waiving of all Events of
Default with respect to the Securities that may have occurred, shall undertake
to perform with respect to the Securities such duties and only such duties as
are specifically set forth in this Indenture, and no implied covenants shall be
read into this Indenture against the Trustee. In case an Event of Default with
respect to the Securities has occurred (that has not been cured or waived), the
Trustee shall exercise with respect to the Securities such of the rights and
powers vested in it by this Indenture, and use the same degree of care and skill
in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

      (b) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

            (i) prior to the occurrence of an Event of Default with respect to
      the Securities and after the curing or waiving of all such Events of
      Default with respect to the Securities that may have occurred:

                  (1) the duties and obligations of the Trustee shall with
            respect to the Securities be determined solely by the express
            provisions of this Indenture, and the Trustee shall not be liable
            with respect to the Securities except for the performance of such
            duties and obligations as are specifically set forth in this
            Indenture, and no implied covenants or obligations shall be read
            into this Indenture against the Trustee; and

                  (2) in the absence of bad faith on the part of the Trustee,
            the Trustee may with respect to the Securities conclusively rely, as
            to the truth of the statements and the correctness of the opinions
            expressed therein, upon any certificates or opinions furnished to
            the Trustee and conforming to the requirements of this Indenture;
            but in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Trustee, the Trustee shall be under a duty to examine the same to
            determine

                                      -61-
<PAGE>

            whether or not they conform to the requirements of this Indenture
            (but need not confirm or investigate the accuracy of any
            mathematical calculations or other facts stated therein);

            (ii) This subsection shall not be construed to limit the effect of
      Section 12.1(b)(v).

            (iii) the Trustee shall not be liable for any error of judgment made
      in good faith by a Trust Officer or Trust Officers, unless it shall be
      proved that the Trustee was negligent in ascertaining the pertinent facts;

            (iv) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the holders of not less than a majority in principal amount
      of the Securities at the time Outstanding (determined as provided in
      Section 2.8) relating to the time, method and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee under this Indenture with
      respect to the Securities; and

            (v) None of the provisions contained in this Indenture shall require
      the Trustee to expend or risk its own funds or otherwise incur personal
      financial liability in the performance of any of its duties or in the
      exercise of any of its rights or powers, if there is reasonable ground for
      believing that the repayment of such funds or liability is not reasonably
      assured to it under the terms of this Indenture or adequate indemnity
      against such risk is not reasonably assured to it.

      (c) Whether or not expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability or affording
protection to the Trustee shall be subject to the provisions of this Section.

Section 12.2. Certain Rights of Trustee

      Except as otherwise provided in Section 12.1:

believed by it in good faith to be genuine and to have been signed or presented
by the proper party or parties;

      (b) Any request, direction, order or demand of the Company mentioned

      (c) The Trustee may consult with counsel and the advice of such counsel or
any Opinion of Counsel shall be full and complete authorization and protection
in respect of any action taken or suffered or omitted hereunder in good faith
and in reliance thereon;

                                      -62-
<PAGE>

      (d) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders, pursuant to the provisions of this Indenture, unless
such Securityholders shall have offered to the Trustee security or indemnity
reasonably satisfactory to it against the costs, expenses and liabilities that
may be incurred therein or thereby;

      (e) The Trustee shall not be liable for any action taken or omitted to be
taken by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture;

      (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or

further inquiry or investigation into such facts or matters as it may see fit;
and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney at the sole cost of the
Company and shall incur no liability or additional liability of any kind by
reason of such inquiry or investigation.

      (g) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

      (h) The Trustee shall not be deemed to have knowledge or be charged with
knowledge of an Event of Default except (i) if the Trustee is acting as Paying
Agent, any Default or Event of Default occurring pursuant to Sections 9.1,

Section 12.5. Moneys Held in Trust

      Subject to the provisions of Section 11.5, all moneys received by the

      (a) The Company covenants and agrees to pay to the Trustee, and the

any provision of law in regard to the compensation of a trustee of an express
trust), as the Company and the Trustee may from time to time agree in writing
for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee, and, except as otherwise expressly provided herein, the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with

and the expenses and disbursements of its counsel and of all Persons not

directors and employees) for, and to hold it harmless against, any loss,
liability or expense incurred without gross negligence or bad faith or willful
misconduct on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the reasonable costs
and expenses of defending itself against any claim of liability in the premises.

this Indenture and resignation or removal of the Trustee.

      (b) The obligations of the Company under this Section to compensate and

as such, except funds held in trust for the benefit of the Holders.

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 11.1(7) or (8) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

      For the purposes of this Section 12.6, the "Trustee" shall include any
predecessor Trustee; provided, however, that the gross negligence, bad faith or
willful misconduct of any Trustee hereunder shall not affect the rights of any
other Trustee hereunder.

Section 12.7. Reliance on Officers' Certificate

      Except as otherwise provided in Section 12.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be

                                      -65-
<PAGE>

proved or established prior to taking or suffering or omitting to take any
action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of bad faith on the part of
the Trustee, be deemed to be conclusively proved and established by an Officers'
Certificate or Opinion of Counsel delivered to the Trustee and such certificate,
in the absence of bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken, suffered or omitted to be taken by it under
the provisions of this Indenture upon the faith thereof.

shall promptly appoint a successor trustee with respect to the Securities by or

Securities and appoint a successor trustee by or pursuant to a resolution of the
Company's Board of Directors, or, unless the Trustee's duty to resign is stayed
as provided herein, subject to Section 11.11, any Securityholder who has been a
bona fide holder of a Security or Securities for at least six months may, on
behalf of that holder and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, remove the Trustee and appoint a successor trustee.

      (c) The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee by so
notifying the Trustee and the Company and may appoint a successor Trustee with
the consent of the Company. If no successor trustee shall have been so appointed
and have accepted appointment within 30 days after such notification of removal
by the Holders, the Trustee to be removed may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to the
Securities, or any Securityholder who has been a bona fide holder of a Security
or Securities for at least six months may on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may, as it may deem proper prescribe or appoint a successor
trustee.

removal of the Trustee and appointment of a successor trustee with respect to
the Securities pursuant to any of the provisions of this Section shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 12.11.

      (e) So long as no event which is, or after notice or lapse of time, or

Trustee (i) a resolution of the Company's Board of Directors appointing a
successor Trustee, effective as of a date specified therein, and (ii) an

                     5.50% CONVERTIBLE SENIOR NOTES DUE 2026

      This Security is one of a duly authorized issue of 5.50% Convertible
Senior Notes due 2026 (the "Securities") of the Company issued under an
Indenture, dated as of November 21, 2006 (the "Indenture"), between the Company
and The Bank of New York, as trustee (the "Trustee"). The terms of the Security
include those stated in the Indenture, those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (the "TIA"), and those
set forth in this Security. This Security is subject to all such terms, and
Holders are referred to the Indenture and the TIA for a statement of all such
terms. To the extent permitted by applicable law, if any provision of this
Security conflicts with the express provisions of the Indenture, the provisions
of the Indenture shall govern and be controlling. Capitalized terms used but not
defined herein have the meanings assigned to them in the Indenture unless
otherwise indicated.

1. Interest.

      Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months as set forth on the face of the Security.

      If this Security is redeemed pursuant to paragraph 5 of this Security, or
the Holder elects to require the Company to purchase this Security pursuant to
paragraph 6 or 7 of this Security, on a date that is after an Interest Payment
Record Date but prior to the corresponding Interest Payment Date, interest and
Additional Interest, if any, accrued and unpaid hereon to, but not including,
the applicable Redemption Date or Fundamental Change Purchase Date shall be paid
to the Holder of this Security as of such Interest Payment Record Date. Interest
and Additional Interest, if any, accrued and unpaid hereon at the Final Maturity
Date also shall be paid to the same Holder to whom the Company pays the
principal of this Security.

      Interest and Additional Interest, if any, on Securities converted after
the close of business on an Interest Payment Record Date but prior to the
corresponding Interest Payment Date shall be paid, on such Interest Payment
Date, to the Holder of the Securities as of the close of business on the
Interest Payment Record Date but, upon conversion, the converting Holder must
pay the Company an amount equal to the interest that shall be payable on such
Interest Payment Date. No such payment need be made with respect to Securities
converted after an Interest Payment Record Date and prior to the corresponding
Interest Payment Date (1) if the Company has specified a Redemption Date that is
after the close of business on an Interest Payment Record Date but on or prior
to the corresponding Interest Payment Date, (2) any overdue interest exists at
the time of conversion with respect to the Securities being converted, but only
to the extent of the amount of such overdue interest, or (3) if the Holder
converts after the close of business on the last Interest Payment Record date
prior to the Final Maturity Date.

                                      A-5
<PAGE>

      Except as otherwise stated herein, any reference herein to interest
accrued or payable as of any date shall include Additional Interest, if any,
accrued or payable on such date as provided in the Indenture or the Registration
Rights Agreement.

2. Method of Payment.

      Payment of the principal of, and interest on, the Securities shall be made
at the office of the Paying Agent in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts. The Holder must surrender this Security to a Paying Agent to
collect payment of principal. Payment of interest on Certificated Securities
shall be made by check mailed to the address of the Person entitled thereto as
such address appears in the Register; provided, however, that Holders with
Securities in an aggregate principal amount in excess of $2.0 million shall be
paid, at their written election, by wire transfer of immediately available
funds. Notwithstanding the foregoing, so long as the Securities are registered
in the name of a Depositary or its nominee, all payments with respect to the
Securities shall be made by wire transfer of immediately available funds to the
account of the Depositary or its nominee.

3. Paying Agent, Registrar, Conversion Agent.

      Initially, the Trustee will act as Paying Agent, Registrar and Conversion
Agent. The Company or any Affiliate of the Company may act as Paying Agent,
Registrar or Conversion Agent, subject to the terms of the Indenture.

4. Indenture.

      The Securities are general unsubordinated unsecured obligations of the
Company limited to $54,500,000 aggregate principal amount. The Indenture does
not limit other debt of the Company, secured or unsecured.

5. Redemption at the Option of the Company.

      At any time on and after November 15, 2011, the Securities may be redeemed
at the option of the Company at any time or from time to time as described
below. Upon any redemption pursuant to Section 3.1 of the Indenture, the Company
shall provide the notice required by Section 3.3 of the Indenture (which notice
may be revoked at any time prior to the time at which the Company or the
Trustee, as the case may be, has given such notice to Securityholders) and shall
pay a Redemption Price in Cash equal to 100% of the principal amount of the
Securities being redeemed, plus any accrued and unpaid interest (including
Additional Interest, if any) to, but excluding, the date fixed for redemption,
payable in Cash.

      A notice of redemption pursuant to this Section of this Security shall be
mailed at least 30 days but not more than 60 days before a Redemption Date to
each Holder of Securities to be redeemed at the Holder's address as such address
appears in the Register. If Cash sufficient to pay the Redemption Price of all
Securities for which notice of redemption is given is deposited with the Paying
Agent by 10:00 a.m., New York City time, on the Redemption Date, then, on and
after such Redemption Date, such Securities shall cease to be outstanding and
interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their

                                      A-6
<PAGE>

Holders to the Paying Agent, and the Holders thereof shall have no rights as
such other than the right to receive the Redemption Price upon delivery of such
Securities to the Paying Agent. Securities in denominations larger than $1,000
principal amount may be redeemed in part but only in multiples of $1,000
principal amount.

6. Purchase by the Company Upon a Fundamental Change.

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase for Cash, at the option of any Holder, all or any
portion of the Securities held by such Holder upon a Fundamental Change in
multiples of $1,000 at the Fundamental Change Purchase Price. To exercise such
right, a Holder shall deliver to the Paying Agent a Fundamental Change Purchase
Notice containing the information set forth in the Indenture, at any time prior
to 5:00 p.m., New York City time, on the Business Day immediately preceding the
Fundamental Change Purchase Date, and shall deliver the Securities to the Paying
Agent as set forth in the Indenture.

      Holders have the right to withdraw any Fundamental Change Purchase Notice
by delivering to the Paying Agent a written notice of withdrawal in accordance
with the provisions of the Indenture.

      If Cash sufficient to pay the Fundamental Change Purchase Price of all
Securities or portions thereof to be purchased with respect to a Fundamental
Change Purchase Date is deposited with the Paying Agent by 10:00 a.m., New York
City time, on the Fundamental Change Purchase Date then, on and after such
Fundamental Change Purchase Date such Securities shall cease to be outstanding
and interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their Holders to the Paying Agent, and the Holders
thereof shall have no rights as such other than the right to receive the
Fundamental Change Purchase Price upon delivery of such Securities to the Paying
Agent.

7. Purchase by the Company at the Option of the Holder on Specified Dates

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase for Cash, at the option of any Holder, all or any
portion of the Securities held by such Holder upon each Purchase Date in
multiples of $1,000 at the Put Option Purchase Price. To exercise such right, a
Holder shall deliver to the Paying Agent a Put Option Notice containing the
information set forth in the Indenture, at any time prior to 5:00 p.m., New York
City time, on the Business Day immediately preceding the Put Option Purchase
Date, and shall deliver the Securities to the Paying Agent as set forth in the
Indenture.

      Holders have the right to withdraw any Put Option Notice by delivering to
the Paying Agent a written notice of withdrawal in accordance with the
provisions of the Indenture.

      If Cash sufficient to pay the Put Option Price of all Securities or
portions thereof to be purchased with respect to a Put Option Purchase Date is
deposited with the Paying Agent by 10:00 a.m., New York City time, on the Put
Option Purchase Date then, on and after such Put Option Purchase Date such

the Paying Agent, and the Holders thereof shall have no rights as such other
than the right to receive the Put Option Purchase Price upon delivery of such
Securities to the Paying Agent.

8. Conversion.

      Subject to the terms and conditions of the Indenture, a Holder of a
Security may convert the principal amount of such Security (or any portion
thereof equal to $1,000 principal amount or any integral multiple of $1,000
principal amount in excess thereof) into shares of Common Stock at any time
prior to 5:00 p.m., New York City time, on the Business Day immediately
preceding the Final Maturity Date, at the Conversion Rate then in effect;
provided, however, that, if such Security is called for redemption pursuant to
paragraph 5, such conversion right shall terminate at the close of business on
the Business Day immediately preceding the Redemption Date, unless there shall
be a default in the payment of the Redemption Price, in which case the
conversion right with respect to such Security shall terminate at 5:00 p.m., New
York City time, on the date such default is cured and such Security is redeemed
in accordance herewith; provided further, that, if a Put Notice with respect to
a Security is delivered in accordance with the Indenture, such Security shall
not be convertible unless such Put Notice is duly withdrawn in accordance with
the Indenture or unless there shall be a default in the payment of the Put
Price, in which case the conversion right with respect to such Security shall
terminate at 5:00 p.m., New York City time, on the date such default is cured
and such Security is purchased in accordance with the Indenture.

      The initial Conversion Rate is 206.7183 shares of Common Stock per $1,000
principal amount of Securities, which represents an initial Conversion Price of
approximately $4.84 per share of Common Stock. The Conversion Rate is subject to
adjustment under certain circumstances as provided in the Indenture. No
fractional shares will be issued upon conversion. In lieu thereof, the Company
shall deliver Cash in an amount equal to the value of such fraction computed on
the basis of the Applicable Stock Price on the Trading Day immediately before
the Conversion Date.

      To convert a Security, a Holder must (i) if the Security is represented by
a Global Security, comply with the Applicable Procedures, or (ii) if the
Security is represented by a Certificated Security, (a) deliver to the
Conversion Agent a duly signed and completed Conversion Notice set forth below,
(b) deliver the Security to the Conversion Agent, (c) deliver to the Conversion
Agent appropriate endorsements and transfer documents if required by the
Conversion Agent and (d) pay any tax or duty, if required pursuant to the
Indenture. A Holder may convert a portion of a Security equal to $1,000 or any
integral multiple thereof.

      A Holder's right to convert a Security may be limited pursuant to Section
7.10 of the Indenture.

      The Company will furnish to any Holder, upon request and without charge,
copies of the certificate of incorporation and by-laws of the Company then in
effect. Any such request may be addressed to the Company or to the Registrar.

9. Make-Whole Premium.

      Subject to the limitations set forth in the Indenture, if a Fundamental
Change occurs prior to November 15, 2011, the Company shall pay the Make-Whole
Premium to Holders of the Securities who convert their Securities on a
Conversion Date that falls within a period that (i) begins at the opening of
business on the date (the "Effective Notice Date") the Fundamental Change
Company Notice with respect to such Fundamental Change is mailed in accordance
with Section 5.1(b) of the Indenture and (ii) ends at the close of business on
the second Trading Day immediately preceding the Fundamental Change Purchase
Date corresponding to such Fundamental Change. The Make-Whole Premium with
respect to a Fundamental Change shall be paid solely in shares of the Common
Stock (other than Cash paid in lieu of fractional shares); provided, however,
that if, in connection with such Fundamental Change, all or substantially all of
the shares of Common Stock have been converted into or exchanged for Cash, other
securities or other property, then such Make-Whole Premium shall be paid in the
same form of consideration into which all or substantially all of the shares of
Common Stock have been converted or exchanged in connection with such
Fundamental Change (other than Cash paid in lieu of fractional interests in any
security or pursuant to dissenters' rights), in accordance with the Indenture.
The Make-Whole Premium will be in addition to, and not in substitution for, any
Cash, securities or other assets otherwise due to Holders of Securities upon
conversion as described in the Indenture.

10. Denominations; Transfer; Exchange.

      The Securities are in registered form, without coupons, in denominations
of $1,000 and integral multiples of $1,000. A Holder may register the transfer
of or exchange Securities in accordance with the Indenture. The Registrar may

transfer documents and to pay certain taxes, assessments or other governmental
charges that may be imposed in relation thereto by law or permitted by the
Indenture.

11. Persons Deemed Owners.

      The registered Holder of a Security may be treated as the owner of such

      The Trustee and the Paying Agent shall return to the Company upon written
request any Cash or securities held by them for the payment of any amount with
respect to the Securities that remains unclaimed for two years, subject to
applicable unclaimed property law. After return to the Company, Holders entitled

creditors unless an applicable abandoned property law designates another person.

13. Amendment, Supplement and Waiver.

      Subject to certain exceptions, the Securities or the Indenture may be
amended or supplemented with the consent of the Holders of at least a majority
in aggregate principal amount of the Securities then outstanding, and, subject

or Event of Default with respect to the Securities and its consequences or

Trustee may amend or supplement the Indenture or the Securities to, among other
things, cure any ambiguity, defect or inconsistency or make any change that does
not adversely affect in any material respect the legal rights under the
Indenture of any Holder.

14. Defaults and Remedies.

      If any Event of Default other than as a result of certain events of
bankruptcy, insolvency or reorganization of the Company occurs and is
continuing, the principal of all the Securities then outstanding plus accrued
and unpaid interest may be declared due and payable in the manner and with the
effect provided in the Indenture. If an Event of Default occurs as a result of
certain events of bankruptcy, insolvency or reorganization of the Company, the
principal amount of the Securities plus accrued and unpaid interest shall become
due and payable immediately without any declaration or other act on the part of
the Trustee or any Holder, all to the extent provided in the Indenture.

15. Trustee Dealings with the Company.

      Subject to certain limitations imposed by the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not the Trustee.

16. No Recourse Against Others.

      No recourse under or upon any obligation, covenant or agreement of the
Company contained in the Indenture, or in this Security, or because of any
indebtedness evidenced thereby or hereby, shall be had against any incorporator,
as such, or against any past, present or future employee, stockholder, officer
or director, as such, of the Company or of any successor, either directly or
through the Company or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the Holders and as part of
