Securities owned, directly or indirectly, by the Company or its Affiliates shall
be deemed not to be outstanding.


     SECTION 2. Shelf Registration Statement.

     (a) The Company agrees to file with the SEC as soon as reasonably
practicable after the Closing Date, but in no event later than the Filing Date,
a Registration Statement for an offering to be made on a continuous basis
pursuant to Rule 415 covering all of the Transfer Restricted Securities or
separate Registration Statements for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Common Stock and Notes
constituting Transfer Restricted Securities, respectively (such Registration
Statement or Statements, collectively, the "Shelf Registration Statement") Each
Shelf Registration Statement shall be on Form S-3 under the Securities Act or
another appropriate form selected by the Company permitting registration of such
Transfer Restricted Securities for resale by the Holders in the manner or
manners reasonably designated by Holders of a majority in interest of Transfer
Restricted Securities being sold. The Company shall not permit any securities
other than the Transfer Restricted Securities to be included in any Shelf
Registration Statement. The Company shall use all reasonable efforts to cause
each Shelf Registration Statement to be declared effective pursuant to the
Securities Act as soon as reasonably practicable following the filing thereof
and to use all reasonable efforts to keep such Shelf Registration Statement
continuously effective under the Securities Act, subject to Section 2(d) hereof,
for two years after the date on which all of the Transfer Restricted Securities
are sold (including those sold pursuant to the option granted to the Initial
Purchasers in the Purchase Agreement) to the Initial Purchasers (the
"Effectiveness Period"), or such shorter period ending when there cease to be
any Transfer Restricted Securities outstanding.


     (b) Supplements and Amendments. The Company shall use all reasonable
efforts to keep each Shelf Registration Statement continuously effective by
supplementing and amending the Shelf Registration Statement if required by the
rules, regulations or instructions applicable to the registration form used for
such Shelf Registration Statement, if required by the Securities Act or if
reasonably requested by the Holders of a majority in interest of the Transfer
Restricted Securities or by any underwriter of such Transfer Restricted
Securities.

     (c) Selling Securityholder Information. Each Holder wishing to sell
Transfer Restricted Securities pursuant to a Shelf Registration Statement and
related Prospectus agrees to deliver a Notice and Questionnaire that confirms
such Holder's agreement to be bound by the terms of this Agreement and includes
such information regarding it and the distribution of its Transfer Restricted
Securities as is required by law to be disclosed by the Holder in the applicable
Registration Statement (the "Requisite Information") to the Company prior to the

                                       5
<PAGE>

effectiveness of the Shelf Registration Statement. The Company shall not be
required to include in any Shelf Registration Statement and related Prospectus
the Transfer Restricted Securities of any Holder that does not provide the
Company with a Notice and Questionnaire in accordance with this Section 2(c).
The Company shall file, within five Business Days after the receipt of a Notice
and Questionnaire from any Holder which includes the Requisite Information with
respect to such Holder, a Prospectus supplement pursuant to Rule 424 or
otherwise amend or supplement such Registration Statement to include in the
Prospectus the Requisite Information as to such Holder (and the Transfer
Restricted Securities held by such Holder), and the Company shall provide such
Holder within five Business Days after receipt of such Notice and Questionnaire
with a copy of such Prospectus as so amended or supplemented containing the
Requisite Information in order to permit such Holder to comply with the
Prospectus delivery requirements of the Securities Act in a timely manner with
respect to any proposed disposition of such Holder's Transfer Restricted
Securities and to file the same with the SEC. Each Holder shall promptly notify
the Company of any material changes to the Requisite Information contained in
the Notice and Questionnaire provided to the Company by such Holder. If the
Company shall fail to file the appropriate supplement or amendment within five
Business Days of receipt of such notice (except where such failure to file is
due to the objection to filing any such amendment or supplement by the holders
of a majority in interest of the Transfer Restricted Securities, or the managing
underwriters, if any, pursuant to Section 4(a)), the Company shall pay the
Holder Liquidated Damages in the manner set forth in Section 3. Furthermore, if
the filing requires a post-effective amendment to the Registration Statement and
such amendment is not declared effective within 45 Business Days of the filing
of the post-effective amendment, the Company shall pay the Holder Liquidated
Damages in the manner set forth in Section 3.

     If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require, in the event that such reference to such Holder by
name or otherwise is not required by the Securities Act or any similar Federal
statute then in force, the deletion of the reference to such Holder in such
Registration Statement at the time subsequent to the time that such reference
ceases to be required and the Company otherwise intends to amend our supplement
the Shelf Registration Statement.

     (d) Material Events; Suspension of Sales. Notwithstanding the provisions
contained in this Section 2, in the event that, in the judgment of the Company's
Board of Directors, it is advisable to suspend use of the Prospectus due to
pending corporate developments, public filings with the SEC or similar events,
the Company shall promptly deliver a written certificate to each registered
Holder, the Trustee, the Transfer Agent and the managing underwriters, if any,
to the effect that the use of the Prospectus is to be suspended until the
Company shall

                                       6
<PAGE>

deliver a written notice that the use of the Prospectus may be resumed.
Thereafter, the use of the Prospectus shall be suspended, and the Company shall
not be required to maintain the effectiveness of, or amend or update the Shelf
Registration Statement, or amend or supplement the Prospectus; provided,
however, that the Company shall only be permitted to suspend the use of the
Prospectus for a period not to exceed 30 days in any six-month period or two
periods not to exceed an aggregate of 60 days in any 12-month period. The
Company will use its best efforts to ensure that the use of the Prospectus may
be resumed as soon as, in the judgment of the Company's Board of Directors,
disclosure of the material relating to such pending development, filing or event
would not have a material adverse effect on the Company.

     (e) Additional Agreements of Holders. Each Holder agrees not to dispose of
Transfer Restricted Securities pursuant to the Shelf Registration Statement
without complying with the prospectus delivery requirements under the Act and
the provisions of paragraph (d) above regarding use of the Prospectus. Each
Holder further agrees that it will comply fully with applicable federal and
state securities laws in connection with the distribution of any Transfer
Restricted Securities pursuant to the Shelf Registration Statement. Each Holder
further acknowledges having been advised by the Company that applicable federal
securities laws prohibit Holders from trading in securities of the Company at
any time while in possession of material non-public information about the
Company.


     SECTION 3. Liquidated Damages.


     (a) The Company and the Initial Purchasers agree that the Holders will
suffer damages if the Company fails to fulfill its obligations pursuant to
Section 2 hereof and that it would not be possible to ascertain the extent of
such damages. Accordingly, the Company hereby agrees to pay liquidated damages
("Liquidated Damages") to each Holder under the circumstances and to the extent
set forth below:

          (i)  if the Shelf Registration Statement has not been filed with the
               SEC on or prior to the Filing Date; or

          (ii) if each Shelf Registration Statement is not declared effective by
               the SEC on or prior to the applicable Effectiveness Target Date;
               or

          (iii) any Shelf Registration Statement ceases to be effective or
               usable at any time during the Effectiveness Period (without being
               succeeded on the same day immediately by a post-effective
               amendment or supplement to such Registration Statement that cures
               such failure and that is itself, in the case of post-effective
               amendment, immediately declared effective) for a period of time
               which shall

                                       7
<PAGE>

               exceed 90 days in the aggregate in any period of 365 consecutive
               days; (any of the foregoing, a "Registration Default").

     In the event of a Registration Default, the Company will pay Liquidated
Damages to each holder of Transfer Restricted Securities, during the first
90-day period immediately following the occurrence of such Registration Default
in an amount equal to $0.05 per week per $1,000 principal amount of Notes
adjusted to an equivalent per share basis in accordance with the conversion
price. The rate of accrual of the Liquidated Damages will increase by $0.05 per
week per $1,000 principal amount of Notes or Common Stock constituting Transfer
Restricted Securities (adjusted to an equivalent per share basis in accordance
with the conversion price for Common Stock constituting Transfer Restricted
Securities) for each subsequent 90-day period until the applicable Registration
Statement is filed, the applicable Registration Statement is declared effective
and becomes available for effecting sales of securities, or the Shelf
Registration Statement again becomes effective and becomes available for
effecting sales of securities, as the case may be, up to a maximum amount of
Liquidated Damages of $0.25 per week per $1,000 principal amount of Notes
adjusted to an equivalent per share basis in accordance with the conversion
price. Following the cure of a Registration Default, Liquidated Damages will
cease to accrue with respect to such Registration Default (without in any way
limiting the effect of any subsequent Registration Default). All accrued
Liquidated Damages shall be paid to the holders of (i) Notes constituting
Transfer Restricted Securities, pursuant to the terms of the Indenture with
respect to the payment of interest and (ii) shares of Common Stock, in the
manner as interest payments on the Notes on semiannual payment dates that
correspond to interest payment dates for the Notes. The parties hereto agree and
acknowledge that the payment of Liquidated Damages to holders of Common Stock
upon a Registration Default pursuant to this Agreement shall not be a dividend
on such shares of Common Stock.

     (b) The Company shall notify the Transfer Agent or the Trustee, as the case
may be, within five Business Days after each and every date on which a
Registration Default occurs. Liquidated Damages , as calculated by the Company,
shall be paid by the Company to the Record Holders of Common Stock on each
Damages Payment Date by wire transfer of immediately available funds to the
accounts specified by them or by mailing checks to their registered addresses as
they appear in the register of the Company for the Common Stock, if no such
accounts have been specified in the Notice and Questionnaire on or before the
Damages Payment Date; and Liquidated Damages shall be paid by the Company to the
Record Holders of the Notes on each semi-annual interest payment date together
with interest to be paid on the Notes pursuant to the terms of the Indenture, by
wire transfer of immediately available funds to the accounts specified by them
or by mailing checks to their registered addresses as they appear in the Notes
Register (as defined in the Indenture) if no such accounts have been specified
in the Notice and Questionnaire on or before the Damages

                                       8
<PAGE>

Payment Date; provided, however, that any Liquidated Damages accrued with
respect to any Notes or portion thereof called for redemption on a redemption
date, repurchased on a repurchase date, or converted into shares of Common Stock
on a conversion date prior to the Damages Payment Date shall, in any such event,
be paid instead to the Holder who submitted such Notes or portion thereof for
redemption, repurchase or conversion on the applicable redemption date,
repurchase date or conversion date, as the case may be, on such date.


     SECTION 4. Registration Procedures. In connection with the Company's
registration obligations hereunder, the Company shall effect such registrations
on the appropriate form selected by the Company to permit the resale of Transfer
Restricted Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall as expeditiously as
reasonably possible:

     (a) No fewer than five Business Days prior to the initial filing of a
Registration Statement or Prospectus and no fewer than two Business Days prior
to the filing of any amendment or supplement thereto (excluding, unless
requested, any document that would be incorporated or deemed to be incorporated
therein by reference and then only to the Holder who so requested), furnish to
the Holders whose Transfer Restricted Securities are required to be included in
such Registration Statement or Prospectus pursuant to Section 2(c) hereof and
the managing underwriters, if any, copies of all such documents proposed to be
filed (excluding, unless requested, those incorporated or deemed to be
incorporated by reference and then only to the Holder who so requested) and
cause the officers and directors of the Company, counsel to the Company and
independent certified public accountants to the Company to respond to such
inquiries as shall be necessary in connection with such Registration Statement,
in the opinion of counsel to the underwriters, if any, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file any such Registration Statement or related Prospectus or any amendments or
supplements thereto (excluding any document that would be incorporated or deemed
incorporated by reference) to which the Holders of a majority in interest of the
Transfer Restricted Securities or the managing underwriters, if any, shall
reasonably object on a timely basis.

     (b) Prepare and file with the SEC such amendments, including post-effective
amendments, to each Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the applicable time period set
forth in Section 2(a) hereof; subject to Section 2(d) hereof, cause the related
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the Securities Act and the
Exchange Act with respect to the disposition of all securities covered by such
Registration Statement during such period in accordance with the intended method
or methods of disposition by the Holder set forth in such Registration

                                       9
<PAGE>

Statement as so amended or in such Prospectus as so supplemented (including,
without limitation, the filing of any Prospectus supplement pursuant to Rule 424
in order to add or change any selling security holder information (including any
such supplements or amendments pursuant to Section 2(c) hereof, provided such
Holder to which such change applies complies with the Requisite Information
requirements of Section 2(c) hereof))

(c) Notify the Holders and the managing underwriters, if any, promptly (and in
the case of an event specified by clause (i) of this paragraph in no event fewer
than two Business Days prior to such filing), and (if requested by any such
person), confirm such notice in writing, (i) when a Prospectus or any Prospectus
supplement or post-effective amendment is proposed to be filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective, (ii) of any request of the SEC or any other Federal
or state governmental authority for amendments or supplements to such
Registration Statement or related Prospectus or for additional information
related thereto, (iii) of the issuance by the SEC, any state securities
commission, any other governmental agency or any court of any stop order, order
or injunction suspending or enjoining the use or the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose,
(iv) if at any time any of the representations and warranties of the Company
contained in any agreement (including any underwriting agreement) contemplated
by Section 4(m) hereof are not true and correct in all material respects, (v) of
the receipt by the Company of any notification with respect to the suspension of
the qualification or exemption from qualification of any of the Transfer
Restricted Securities for sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose, and (vi) of the existence of any
fact and the happening of any event that makes any statement made in such
Registration Statement or related Prospectus untrue in any material respect, or
that requires the making of any changes in such Registration Statement or
Prospectus so that in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading and that, in the case of the Prospectus, such Prospectus will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

     (d) Use all reasonable efforts to avoid the issuance of, or, if issued, to
obtain the withdrawal of any stop order or order enjoining or suspending the use
or effectiveness of a Registration Statement or the lifting of any suspension of
the qualification (or exemption from qualification) of any of the Transfer
Restricted Securities for sale in any jurisdiction, at the earliest practicable
moment.

     (e) If requested by the managing underwriters, if any, or the Holders of a
majority in interest of the Transfer Restricted Securities being sold in
connection with such offering, promptly include in a Prospectus supplement or
post-effective

                                       10
<PAGE>

amendment such information as the managing underwriters, if any, and such
Holders agree should, in their reasonable judgment, be included therein, and
make all required filings of such Prospectus supplement or such post-effective
amendment as soon as reasonably practicable after the Company has received
notification of the matters to be included in such Prospectus supplement or
post-effective amendment; provided, however, that the Company shall not be
required to take any action pursuant to this Section 4(e) that, in the opinion
of counsel for the Company, would violate applicable law;

     (f) Furnish to each Holder who so requests and each managing underwriter,
if any, without charge, at least one conformed copy of each Registration
Statement and each amendment thereto, including financial statements (but
excluding schedules, all documents incorporated or deemed to be incorporated
therein by reference and all exhibits, unless requested in writing by such
Holder or any managing underwriter);

     (g) Deliver to each Holder and the underwriters, if any, without charge, as
many copies of the Prospectus or Prospectuses (including each form of
Prospectus) and each amendment or supplement thereto to as such persons may
reasonably request; and, unless the Company shall have given notice to such
Holder pursuant to Section 2(d), the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders of Transfer Restricted Securities and the underwriters, if any, in
connection with the offering and sale of the Transfer Restricted Securities
covered by such Prospectus and any amendment or supplement thereto, provided,
however, that no Holder shall be entitled to use the Prospectus unless and until
such Holder shall have furnished to the Company any and all Requisite
Information pursuant to Section 2(c) hereof;

     (h) Use all reasonable efforts to register or qualify, or cooperate with
the Holders of Transfer Restricted Securities to be sold or tendered for, the
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of, such Transfer Restricted Securities for offer and sale under
the securities or Blue Sky laws of such jurisdictions within the United States
as any Holder or underwriter reasonably requests in writing, keep each such
registration or qualification (or exemption therefrom) effective during the
period such Registration Statement is required to be kept effective and do any
and all other acts or things necessary legally to enable the disposition in such
jurisdictions of the Transfer Restricted Securities covered by the applicable
Registration Statement; provided, however, that the Company shall not be
required to qualify generally to do business in any jurisdiction where it is not
then so qualified, take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject or subject the
Company to any tax in any such jurisdiction where it is not then so subject;

                                       11
<PAGE>

     (i) In connection with any sale or transfer of Transfer Restricted
Securities that will result in such securities no longer being Transfer
Restricted Securities, cooperate with the Holders and the managing underwriters,
if any, to facilitate the timely preparation and delivery of certificates
representing Transfer Restricted Securities to be sold, which certificates shall
not bear any restrictive legends, shall bear a CUSIP number different from the
CUSIP number for the Transfer Restricted Securities and shall be in a form
eligible for deposit with The Depository Trust Company and enable such Transfer
Restricted Securities to be in such denominations and registered in such names
as the managing underwriters, if any, or Holders may reasonably request at least
two Business Days prior to any sale of Transfer Restricted Securities;

     (j) Use all reasonable efforts to cause the offering of the Transfer
Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States, except as may be required as a consequence of the nature of a
Holder's business, in which case the Company will cooperate in all reasonable
respects with the filing of such Registration Statement and the granting of such
approvals as may be reasonably necessary to enable the seller or sellers thereof
or the underwriters, if any, to consummate the disposition of such Transfer
Restricted Securities; provided, however, that the Company shall not be required
to register the Transfer Restricted Securities in any jurisdiction that would
require the Company to qualify to do business in any jurisdiction where it is
not then so qualified, subject it to general service of process in any such
jurisdiction where it is not then so subject or subject the Company to any tax
in any such jurisdiction where it is not then so subject or to;

     (k) Upon the occurrence of any event contemplated by Section 4 (vi) hereof,
as promptly as reasonably practicable (subject to any suspension of sales
pursuant to Section 2(d) hereof), prepare a supplement or amendment, including,
if appropriate, a post-effective amendment, to each Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, such Prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading;

     (l) Prior to the effective date of the first Registration Statement
relating to the Transfer Restricted Securities, to provide a CUSIP number for
the Transfer Restricted Securities to be sold pursuant to the Registration
Statement;

     (m) Enter into such agreements (including any underwriting agreements in
form, scope and substance as are customary in underwritten offerings) reasonably
satisfactory to the Company and take all such other reasonable actions in

                                       12
<PAGE>

connection therewith (including those reasonably requested by the managing
underwriters, if any, or the Holders of a majority in interest of the Transfer
Restricted Securities being sold) in order to expedite or facilitate the sale of
such Transfer Restricted Securities; provided, however, that the Company is not
required to facilitate an underwritten offering without its consent. In such
connection, whether or not an underwriting agreement is entered into and whether
or not the registration is an underwritten registration, the Company will: (i)
make such representations and warranties to the Holders of such Transfer
Restricted Securities and the underwriters, if any, with respect to the business
of the Company and its subsidiaries (including with respect to businesses or
assets acquired or to be acquired by any of them), and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, in form, substance and scope as
are customarily made by issuers to underwriters in underwritten offerings and
reasonably acceptable to the Company, and confirm the same if and when
requested; (ii)seek to obtain opinions of counsel to the Company and updates
thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the managing underwriters, if any, addressed to each
selling Holder of Transfer Restricted Securities and each of the underwriters,
if any, covering the matters customarily covered in opinions requested in
underwritten offerings (including any such matters as may be reasonably
requested by such underwriters); (iii) use all reasonable efforts to obtain
customary "cold comfort" letters and updates thereof from the independent
certified public accountants of the Company (and, if necessary, any other
independent certified public accountants of any subsidiary of the Company or of
any business acquired by the Company for which financial statements and
financial data is, or is required to be, included in the Registration
Statement), addressed (where reasonably possible) to each selling Holder of
Transfer Restricted Securities and each of the underwriters, if any, such
letters to be in customary form and covering matters of the type customarily
covered in "cold comfort" letters in connection with underwritten offerings;
(iv) if an underwriting agreement is entered into, the same shall contain
indemnification provisions and procedures no less favorable to the selling
Holders of Transfer Restricted Securities and the underwriters, if any, than
those set forth in Section 6 hereof (or such other provisions and procedures
acceptable to Holders of a majority in interest of the Transfer Restricted
Securities covered by such Registration Statement and the managing
underwriters); and (v) deliver such documents and certificates as may be
reasonably requested by the Holders of majority interest of the Transfer
Restricted Securities being sold or the managing underwriters, if any, to
evidence the continued validity of the representations and warranties made
pursuant to clause (i) of this Section 4(m) and to evidence compliance with any
customary conditions contained in the underwriting agreement or other agreement
entered into by the Company;


     (n) Make available for inspection by a representative of the Holders of
Transfer Restricted Securities being sold, any underwriter participating in any

                                       13
<PAGE>

such disposition of Transfer Restricted Securities, if any, and any attorney,
consultant or accountant retained by such selling Holders or underwriter, at the
offices where normally kept, during reasonable business hours, all financial and
other records, pertinent corporate documents and properties of the Company and
its subsidiaries as they may reasonably request, and cause the officers,
directors, agents and employees of the Company and its subsidiaries to supply
all information in each case reasonably requested by any such representative,
underwriter, attorney, consultant or accountant in connection with such
Registration Statement, provided, however, that such persons shall first agree
in writing with the Company that any information that is reasonably and in good
faith designated by the Company in writing as confidential at the time of
delivery or inspection (as the case may be) of such information shall be kept
confidential by such persons, unless (i) in the reasonable opinion of the
Company or its counsel, disclosure of such information is required by court or
administrative order or is necessary to respond to inquiries of regulatory
authorities, (ii) in the reasonable opinion of the Company or its counsel,
disclosure of such information is required by law (including any disclosure
requirements pursuant to Federal securities laws in connection with the filing
of any Registration Statement or the use of any Prospectus), (iii) such
information becomes generally available to the public other than as a result of
a disclosure or failure to safeguard by any such person or (iv) such information
becomes available to any such person from a source other than the Company and
such source is not bound by a confidentiality agreement.

     (o) Use all reasonable efforts to cause the Indenture to be qualified under
the TIA not later than the effective date of the first Registration Statement
relating to the Transfer Restricted Securities; and in connection therewith,
cooperate with the Trustee and the Holders of Notes or Common Stock constituting
Transfer Restricted Securities to effect such changes to the Indenture, if any,
as may be required for such Indenture to be so qualified in accordance with the
terms of the TIA; and execute, and use its best efforts to cause the Trustee to
execute, all customary documents as may be required to effect such changes, and
all other forms and documents (including Form T-1) required to be filed with the
SEC to enable the Indenture to be so qualified under the TIA in a timely manner.

     (p) Comply with applicable rules and regulations of the SEC and make
generally available to its security holders earning statements satisfying the
provisions of Section 11(a) of the Securities Act or Rule 158 (or any similar
rule promulgated under the Securities Act), no later than 45 days after the end
of any 12-month period (or 90 days after the end of any 12- month period if such
period is a fiscal year) commencing at the end of any fiscal quarter in which
Transfer Restricted Securities are sold to underwriters in a firm commitment or
best efforts underwritten offering and if not sold to underwriters in such an
offering, commencing on the first day of the first fiscal quarter after the
effective date of a

                                       14
<PAGE>

Registration Statement, which statement shall cover said period, consistent with
the requirements of Rule 158; and

     (q) (i) list all shares of Common Stock covered by any Registration
Statements on any securities exchange on which the Common Stock is then listed
or (ii) authorize for quotation on the SmallCap Market or the National Market of
the National Association of Securities Dealers Automated Quotation System
("Nasdaq") all Common Stock covered by all such Registration Statements if the
Common Stock is then so authorized for quotation.

     SECTION 5. Registration Expenses.

     All fees and expenses incident to the performance of or compliance with
this Agreement by the Company shall be borne by it whether or not any
Registration Statement is filed or becomes effective and whether or not any
securities are offered or sold pursuant to any Registration Statement.  The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filings fees (including, without
limitation, fees and expenses with respect to filings required to be made with
the National Association of Securities Dealers, Inc. and in compliance with
securities or Blue Sky laws (including, without limitation and in addition to
that provided for in this Section 5, fees and disbursements of counsel for the
underwriters in connection with Blue Sky qualifications of the Transfer
Restricted Securities and determination of the eligibility of the Transfer
Restricted Securities for investment under the laws of such jurisdictions as the
managing underwriters, if any, or Holders of a majority in interest of Transfer
Restricted Securities, may designate)), (ii) printing expenses (including,
without limitation, of printing Prospectuses if the printing of Prospectuses is
required by the managing underwriters, if any, or by the Holders of a majority
in interest of the Transfer Restricted Securities included), (iii) messenger,
telephone and delivery expenses, (iv) reasonable fees and disbursements of
counsel for the Company (plus any local counsel deemed appropriate by the
Holders of a majority in interest of the Transfer Restricted Securities) in
accordance with the provisions of this Section 5 hereof, (v) fees and
disbursements of all independent certified public accountants referred to in
Section 4(m)(iii) (including, without limitation, the expenses of any special
audit and "comfort" letters required by or incident to such performance), (vi)
fees and expenses of all other persons retained by the Company.  In addition,
the Company shall pay its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of an annual audit and the fees and expenses
incurred in connection with the listing of the securities to be registered on
any securities exchange or the Nasdaq SmallCap Market or the Nasdaq National

any Transfer Restricted Securities sold by it.

     SECTION 6. Indemnification.

     (a) The Company agrees to indemnify and hold harmless each of (i) the
Initial Purchasers, (ii) each Holder, (iii) each person, if any, who controls
(within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) any of the foregoing (any of the persons referred to in this
clause (iii) being hereinafter referred to as a "controlling person"), and (iv)
the respective officers, directors, partners, employees, representatives and
agents of the Initial Purchasers, the Holders (including predecessor Holders),
or any controlling person (any person referred to in clause (i), (ii), (iii) or
(iv) may hereinafter be referred to as an "Indemnified Person"), from and
against any and all losses, claims, damages, liabilities, expenses and judgments
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement or Prospectus or in any amendment or
supplement thereto or in any preliminary Prospectus, or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of any
Prospectus or supplement thereto, in the light of the circumstances under which
they were made) not misleading, except insofar as such losses, claims, damages,
liabilities, expenses or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Indemnified Person furnished to the Company by or on behalf of such
Indemnified Person expressly for use therein (which shall include, without
limitation, the Requisite Information in the Notice and Questionnaire provided
to the Company by such Indemnified Person); provided, however, that the
foregoing indemnity with respect to any preliminary Prospectus shall not inure
to the benefit of any Indemnified Person from whom the person asserting such
losses, claims, damages, liabilities, expenses and judgments purchased
securities if such untrue statement or omission or alleged untrue statement or
omission made in such preliminary Prospectus is eliminated or remedied in the
Prospectus and a copy of the Prospectus shall not have been furnished to such
person in a timely manner due to the wrongful action or wrongful inaction of
such Indemnified Person, whether as a result of negligence or otherwise.

     (b) In case any action shall be brought against any Indemnified Person,
based upon any Registration Statement or any such Prospectus or any amendment or
supplement thereto and with respect to which indemnity may be sought against the
Company, such Indemnified Person shall promptly notify the Company in writing
and the Company shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Person and payment of all
fees and expenses. Any Indemnified Person shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Person, unless the employment of such counsel shall have been
specifically authorized in writing by the Company, the Company shall have failed

                                       16
<PAGE>

to assume the defense and employ counsel or such Indemnified Person or Persons
shall have been advised by counsel that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action or proceeding or that there may
be legal defenses available to such Indemnified Person or Persons different from
or in addition to those available to the indemnifying party or parties (in which
case the Company shall not have the right to assume the defense of such action
on behalf of such Indemnified Person, it being understood, however, that the
Company shall not, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all such Indemnified Persons, which firm shall be designated in
writing by such Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred). The Company shall not be liable for any
settlement of any such action effected without its written consent but if
settled with the written consent of the Company, the Company agrees to indemnify
and hold harmless any Indemnified Person from and against any loss or liability
by reason of such settlement. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any pending
or threatened proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

     (c) In connection with any Registration Statement pursuant to which any
Holder (or predecessor Holder) sold or offered for resale Transfer Restricted
Securities, such Holder agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, officers, employees, representatives and
agents and any person controlling the Company within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act, to the same extent as
the foregoing indemnity from the Company to each Indemnified Person but only
with reference to information relating to such Indemnified Person furnished by
or on behalf of such Indemnified Person expressly for use in such Registration
Statement (which shall include, without limitation, the Requisite Information in
the Notice and Questionnaire provided to the Company by such Indemnified
Person). In case any action shall be brought against the Company, any of its
directors, officers, employees, representatives and agents, or any person
controlling the Company based on such Registration Statement and in respect of
which indemnity may be sought against any Indemnified Person, the Indemnified
Person shall have the rights and duties given to the Company (except that if the
Company shall have assumed the defense thereof, such Indemnified Person shall
not be required to do so, but may employ separate counsel therein and
participate in defense thereof but the fees and expenses of such counsel shall
be at the expense of such Indemnified Person), and the Company, its directors,
officers,

                                       17
<PAGE>

employees, representatives and agents, and any person controlling the Company
shall have the rights and duties given to the Indemnified Person by Section 6(b)
hereof.

     (d) If the indemnification provided for in this Section 6 is applicable by
its terms but unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities, expenses or judgments referred to therein, then
each indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities, expenses and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and each Indemnified Person on the other hand pursuant
to the Purchase Agreement or from the offering for resale of the Transfer
Restricted Securities or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company and each such Indemnified Person in connection
with the statements or omissions which resulted in such losses, claims, damages,
liabilities, expenses or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and each such Indemnified
Person shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Company or such Indemnified
Person and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     The Company, the Holders and the Initial Purchasers agree that it would not
be just and equitable if contribution pursuant to this Section 6(d) were
determined by pro rata allocation (even if the Indemnified Person were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities, expenses or judgments
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 6, no Indemnified Person shall be required to contribute any amount in
excess of the amount by which the total net profit received by it in connection
with the sale of the Transfer Restricted Securities pursuant to this Agreement
exceeds the amount of any damages which such Indemnified Person has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Indemnified

                                       18
<PAGE>

Persons' obligations to contribute pursuant to this Section 6(d) are several in
proportion to the respective amount of Transfer Restricted Securities included
in and sold pursuant to any such Registration Statement by each Indemnified
Person and not joint.

     SECTION 7. Underwritten Registration.

     If any of the Transfer Restricted Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be investment bankers of recognized national
standing selected by the Holders of a majority in interest of such Transfer
Restricted Securities included in such offering, subject to the consent of the
Company (which will not be unreasonably withheld or delayed).

     No person may participate in any underwritten registration hereunder unless
such person 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 completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up agreements and other documents reasonably required under the
terms of such underwriting arrangements.

     SECTION 8. Miscellaneous.

     (a) Remedies. In the event of a breach by the Company or by a Holder of any
of their respective obligations under this Agreement, each Holder or the
Company, in addition to being entitled to exercise all rights granted by law,
including, without limitation, recovery of damages, will be entitled to specific
performance of its rights under this Agreement. The Company and each Holder
agree that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of any of the provisions of this Agreement
and hereby further agree that, in the event of any action for specific
performance in respect of such breach, they shall waive the defense that a
remedy at law would be adequate. This Section 8(a) shall not apply to any breach
for which Liquidated Damages have been specifically provided hereunder.

     (b) No Inconsistent Agreements. The Company shall not enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The Company is not currently a party to any agreement
granting any registration rights with respect to any of its securities to any
person which conflicts with the Company's obligations hereunder. Without
limiting the generality of the foregoing, without the written consent of the
Holders of a majority in interest of the Transfer Restricted Securities, the
Company shall not grant to any person the right to request it to register any of
its securities under the Securities Act unless

                                       19
<PAGE>

the rights so granted are subject in all respect to the prior rights of the
Holders set forth herein, and are not otherwise in conflict or inconsistent with
the provisions of this Agreement.

     (c) No Adverse Action Affecting the Transfer Restricted Securities. The
Company will not take any action with respect to the Transfer Restricted
Securities which would adversely affect the ability of any of the Holders to
include such Transfer Restricted Securities in a registration undertaken
pursuant to this Agreement.

     (d) No Piggyback on Registrations. After the date hereof, the Company shall
not grant to any of its security holders (other than the Holders in such
capacity) the right to include any of its securities in any Shelf Registration
Statement.

     (e) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof, may not be given,
without the written consent of the Holders of a majority in interest of the
Transfer Restricted Securities; provided, however, that, for the purposes of
this Agreement, Transfer Restricted Securities that are owned, directly or
indirectly, by either the Company or an Affiliate of the Company are not deemed
outstanding. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose Transfer Restricted Securities are being sold pursuant
to an underwritten offering and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority in interest of the
Transfer Restricted Securities being sold by such Holders pursuant to such an
underwritten offering; provided, however, that the provisions of this sentence
may not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence.

     (f) Notices. All notices and other communications provided for herein shall
be made in writing by hand-delivery, next day air courier, certified first-class
mail, return receipt requested or telecopy:

               (i) if to a Holder, to the address of such Holder as it appears

shall be deemed to have been duly given, when delivered by hand, if personally
delivered; one Business Day after being timely delivered to a next-day air
courier, five Business Days after being deposited in the mail, postage prepaid,
if mailed; and when receipt is acknowledged by the recipient's telecopier
machine, if telecopied.

     (g) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors and permitted assigns of each of the parties
and shall inure to the benefit of each existing and future Holder. The Company
may not assign its rights or obligations hereunder without the prior written
consent of the Holders of a majority in interest of the Transfer Restricted
Securities, other than by operation of law pursuant to a merger or consolidation
to which the Company is a party.

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

     (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED WITHIN THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW.

     (j) Severability. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

Section or paragraph of this Agreement, unless expressly stated otherwise.

     (l) Attorneys' Fees. In any action or proceeding brought to enforce any
provision of this Agreement, or where any provision hereof is validly asserted
as a defense, the prevailing party, as determined by the court, shall be
entitled to recover its reasonable attorneys' fees in addition to any other
available remedy.

6.   Plan of Distribution:

     Except as set forth below, the undersigned (including its donees or
     pledgees) intends to distribute the Transfer Restricted Securities listed
     above in Item (3) pursuant to the Shelf Registration Statement only as
     follows (if at all): Such Transfer Restricted Securities may be sold from

     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 cresses or block transactions) (i) on
     any national securities exchange or quotation service on which the Transfer
     Restricted Securities may be listed or quoted at the time of sale, (ii) in
     the over-the-counter market, (iii) in transactions otherwise than on such
     exchanges or services or in the over-the-counter market, or (iv) through
     the writing of options.  In connection with sales of the Transfer
     Restricted Securities or otherwise, the undersigned may enter into hedging
     transactions with broker-dealers, which may in turn engage in short sales
     of the Transfer Restricted Securities in the course of hedging the
     positions they assume.  The Selling Securityholder may also sell Transfer
     Restricted Securities short and deliver Transfer Restricted Securities to
     close out such short positions, or loan or pledge Transfer Restricted
     Securities to broker-dealers that in turn may sell such securities.

     State any exceptions here:

with the provisions of the Exchange Act and the rules thereunder relating to

or regulations), in connection with any offering of Transfer Restricted
