     Underwritten Registration or Underwritten Offering:

     2.   Shelf Registration.

           (a)  The Company shall prepare and file with
the SEC, as soon as practicable but in any event on or
prior  to the  date  90  days  following the latest date
of  original issuance  of  the Notes (the "Filing
Date"), a  Registration Statement  for an offering to be
made on a continuous  basis pursuant  to  Rule  415  of
the Securities  Act  (a  "Shelf Registration")
registering the resale from time to  time  by Holders
thereof  of all of the Registrable Securities  (the
"Initial   Shelf Registration").    The   Initial
Shelf Registration  shall  be on an appropriate  SEC
Registration Statement  form permitting registration of
such  Registrable Securities  for  resale by such
Holders in  the  manner  or manners  designated by them
(including, without  limitation, one  or more
Underwritten Offerings).  The Company shall use its best
efforts to cause the Initial Shelf Registration  to be
declared effective under the Securities Act as  soon  as
practicable  but in any event on or prior to  the  date
120 days  following  the Filing Date (the "Effectiveness
Target Date"),  and shall use its best efforts to keep
the Initial Shelf   Registration   continuously
effective under   the Securities  Act, subject to the
provisions of Section  2(c), until  the  earlier  of the
expiration of the  Effectiveness Period  or  the  date
a Subsequent Shelf  Registration  (as defined  below)
covering all of the Registrable  Securities has  been
declared  effective under  the  Securities  Act. Subject
to  the  right of the Company to have  the  Initial
Shelf  Registration not be effective, or not to be
updated, amended  or supplemented, for periods of time
set  forth  in Section 2(c), the Company further agrees
to  use  its  best efforts  to  prevent the happening of
any event  that would cause  the Initial Shelf
Registration to contain a material misstatement or
omission or to be not effective and  usable for   resale
of  the  Registrable  Securities during   the Effective
Period.

           (b)   If  the Initial Shelf Registration  or
any
subsequent Shelf Registration ceases to be effective for
any reason  as a result of the issuance of a stop order
by  the SEC at any time during the Effectiveness Period,
the Company shall  use  its best efforts to obtain the
prompt withdrawal of  any  order suspending the
effectiveness thereof, and  in any  event  shall  within
30  days  of  such  cessation  of effectiveness  amend
the  Shelf Registration  in  a  manner reasonably
expected to obtain the withdrawal of  the  order
suspending  the effectiveness thereof, or file an
additional Shelf   Registration   covering  all  of
the Registrable Securities  (a  "Subsequent  Shelf
Registration").   If   a Subsequent  Shelf Registration
is filed, the  Company  shall use   its  best  efforts
to cause  the  Subsequent   Shelf Registration to be
declared effective as soon as practicable after  such
filing and to keep such Registration  Statement
continuously effective until the end of  the
Effectiveness Period.

           (c)   In  the event (A) of the happening  of
any
event  of the kind described in Section 3(c)(ii),
3(c)(iii), 3(c)(iv),  3(c)(v) or 3(c)(vi) hereof or (B)
that,  in  the good  faith  judgment of the Company,  it
is  advisable  to suspend  the use of the Prospectus for
a discrete period  of time  due  to  pending  material
corporate  developments  or similar  material  events
that have not  yet  been  publicly
disclosed  and  as  to  which the  Company  believes
public disclosure  will be prejudicial to the Company,
the Company shall  deliver  a  certificate  in  writing,
signed  by  an authorized executive officer of the
Company, to the  Special Counsel,                    the
Initial   Purchasers   and   the
Managing
Underwriters,  if  any, to the effect of the  foregoing
and thereafter the use of the Prospectus shall be
suspended, and the  Company,  subject to the terms of
this  Section  2(c), shall
thereafter   not  be  required   to   maintain      the
effectiveness or update the Shelf Registration.  The
Company will  use  its best efforts to ensure that the
use  of  the Prospectus  may  be resumed as soon as
practicable,  in  the case  of suspension under Section
2(c)(A), and, in the  case of  a  pending development or
event referred to  in  Section 2(c)(B)  hereof,  as soon
as, in the good faith-judgment  of the  Company,  public
disclosure of such material  corporate development  or
similar material event  would  not  have  a material
adverse effect on the Company.  Notwithstanding the
foregoing, the Company shall not under any circumstances
be entitled  to exercise its right under this Section
2(c)  to suspend  the use of the Prospectus (whether as
a result  of events  referred to in Section 2(c)(A)
hereof or as a result of  the  pending development or
event referred to in Section 2(c)(B)  hereof)  more than
one (1) time in  any  three  (3) month  period,  and
the periods in which  the  use  of  the Prospectus  is
suspended shall not exceed 15  days  in  any three-month
period (a "Suspension Period").

           (d)  The parties hereto agree that the
Holders of Registrable  Securities will suffer  damages,
and that  it would  not  be  feasible to ascertain  the
extent  of  such damages with   precision,  if  (i)
the
Initial   Shelf Registration  has not been filed on or
prior to  the  Filing Date,  (ii)  the  Initial Shelf
Registration  has  not  been declared  effective by the
Effectiveness Target Date,  (iii) prior  to the end of
the Effectiveness Period, the SEC shall have issued a
stop order suspending the effectiveness of the Shelf
Registration or proceedings have been initiated  with
respect to the Shelf Registration under Section 8(d) or
8(e) of  the Securities Act, (iv) the aggregate number
of days in any  one  Suspension  Period exceeds  the
period permitted pursuant  to  Section  2(c) hereof  or
(v)  the number  of Suspension Periods exceeds the
number permitted pursuant  to Section  2(c) hereof (each
of the events of a type described in  any  of  the
foregoing  clauses  (i) through  (v)  are individually
referred  to herein as  an "Event,"  and  the Filing
Date  in  the case of clause (i), the  Effectiveness
Target  Date in the case of clause (ii), the date  on
which the effectiveness  of  the
Shelf  Registration  has  been suspended   or
proceedings with  respect  to   the   Shelf Registration
under Section 8(d) or 8(e) of  the  Securities Act  have
been commenced in the case of clause  (iii),  the date
on
which the duration of a Suspension Period  exceeds the
period permitted by Section 2(c) hereof in the case  of
clause  (iv),  and  the  date  of  the  commencement  of
a Suspension  Period that causes the limit on  the
number of Suspension Periods under Section 2(c) hereof
to be exceeded in  the case of clause (v), being
referred to herein  as  an "Event  Date").
Notwithstanding the foregoing, the  parties hereto
agree  that  an Event shall be deemed  not  to  have
occurred  to the extent the parties mutually agree that
the direct, proximate cause of said Event was the act or
failure to act of one or more Holders, the Initial
Purchasers or the Managing Underwriters.  Events shall
be deemed to  continue until the date of the termination
of such Event, which shall be the following dates with
respect to the respective types of  Events:  the date
the Initial Registration Statement is filed  in  the
case  of an Event of the type described  in clause  (i),
the  date  the Initial Shelf Registration  is declared
effective in the case of clause (ii), the date that all
stop  orders  suspending effectiveness  of  the  Shelf
Registration have been removed and the proceedings
initiated with respect to the Shelf Registration under
Section 8(d) or 8(e) or the Securities Act have
terminated, as the case  may be,  in the case of Events
of the types described in clause (iii), termination of
the Suspension Period which caused the aggregate  number
of days in any one Suspension  Period to exceed  the
number permitted by Section 2(c) to be exceeded in the
case of Events of the types described in clause (iv),
and  termination of the Suspension Periods, the
commencement of  which  caused the number of Suspension
Periods permitted by  Section 2(d) to be exceeded in the
case of Events of the type described in clause (v).
     Accordingly, upon the occurrence of any Event and
until such time as there are no Events which have
occurred and are continuing (a "'Damages Accrual
Period"), commencing on  the Event  Date on which such
Damages Accrual Period began,  the Company agrees to
pay, as liquidated damages, and not  as  a penalty,  an
additional amount (the "Liquidated  Damages"): (i) to
each holder of Notes that are Registrable Securities,
accruing at  a  rate equal to one-half of one  percent
per annum (50 basis points) on the aggregate principal
amount of Notes  that  are Registrable Securities held
by such Holder and  (ii) to each holder of shares of
Common Stock that  are Registrable Securities, accruing
at a rate equal to one-half of  one percent per annum
(50 basis points) calculated on an amount  equal  to
the  product of (x) the  then-applicable Conversion
Price (as defined in the Indenture),  times  (y) the
number  of shares of Common Stock that are  Registrable
Securities   held  by  such holder.   Notwithstanding
the
foregoing,  no  Liquidated Damages shall accrue  as  to
any Registrable Securities from and after the earlier of
(x) the date  such  securities are no longer Registrable
Securities, and  (y)  the  expiration of the
Effectiveness Period.    The
rate  of  accrual of the Liquidated Damages with respect
to any  period shall not exceed the rate provided for
in this paragraph   notwithstanding  the  occurrence
of multiple concurrent Events.

   The Company shall pay the Liquidated Damages due on
any Notes  or Common Stock by depositing with the
Trustee under the  Indenture, in trust, for the benefit
of the
holders  of Notes or Common Stock, as the case may be,
entitled thereto, at  least  one Business Day prior to
the applicable  Damages Payment  Date, sums sufficient
to pay the Liquidated Damages accrued or accruing since
the last preceding Damages Payment Date  through  such
Damages Payment Date.   The  Liquidated Damages  shall
be paid by the Company to the Record  Holders on each
Damages Payment Date by wire transfer of immediately
available  funds  to the account specified  by  them  or
by mailing checks to their registered addresses as they
appear in  the Note register (as defined in the
Indenture), in  the case  of the Notes, and in the
register of the Company  for the Common  Stock, in the
case of the Common Stock,  if  no such  accounts have
been specified on or before  the Damage Payment Date;
provided, however, that any Liquidated Damages accrued
with respect to any Note or portion thereof  called for
redemption  on  a redemption date,  or  repurchased  in
connection  with  a  Change in Control (as  defined  in
the Indenture)  on a repurchase date, or converted  into
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 Note  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
(or  promptly  following  the conversion date, in the
case of conversion of a Note).  If a holder  of  a Note
submits a Note for conversion during  the period
between a record date for the payment of  Liquidated
Damages  and  the related Damages Payment Date,
Liquidated Damages for the period from the conversion
date through  the next succeeding Damages Payment Date
shall  accrue  and  be payable to the holder of Common
Stock received on conversion on the next succeeding
Damages Payment Date, notwithstanding that  such  holder
was not a Record Holder with  respect  to such  Damages
Payment Date.  The Trustee shall be  entitled, on
behalf of the Holders of Notes and Common Stock to  seek
any  available remedy for the enforcement of this
Agreement, including  for  the payment  of  such
Liquidated  Damages. Nothing  shall preclude a Holder of
Registrable  Securities from pursuing  or obtaining
specific performance  or  other equitable relief with
respect to this Agreement.
   All  of  the  Company's obligations set forth  in
this Section  2(d)  which  are outstanding with
respect to  any Registrable Securities at the time such
security ceases  to be  a Registrable Security shall
survive until such time  as all such obligations with
respect to such security have been satisfied  in  full
(notwithstanding termination  of the
Agreement pursuant to Section 7(o)).

     The  parties  hereto agree that the Liquidated
Damages provided  for  in this Section 2(d) constitute
a reasonable estimate  of the damages that may be
incurred by holders  of Registrable  Securities (other
than the Initial  Purchasers) by  reason  of the
failure of the Shelf Registration  to  be filed or
declared effective or unavailable (absolutely or as a
practical  matter) for effecting resales  of
Registrable Securities,  as  the case may be, in
accordance  with  the provisions hereof.
     3.    Registration Procedures.  In connection with
the
Company's  registration obligations under Section 2
hereof, the  Company shall effect such registrations to
permit  the sale  of  the Registrable Securities in
accordance with  the intended  method  or  methods of
disposition  thereof,  and pursuant  thereto  the
Company shall  as  expeditiously  as possible:
           (a)  Prepare and file with the SEC a
Registration Statement or Registration Statements on any
appropriate form under  the  Securities Act available
for the  sale  of  the Registrable Securities by the
Holders thereof in  accordance with  the intended method
or methods of distribution thereof and shall include all
required financial statements, and use its  best
efforts to cause each such Registration Statement to
become effective and remain effective as provided
herein; provided,        that   before  filing,  any
such
Registration Statement  or  Prospectus or any amendments
or  supplements thereto  the Company shall furnish
within a reasonable  time period  to each Selling Holder
(if requested by such Selling Holder), the Initial
Purchasers, the Special Counsel and the Managing
Underwriters of such offering, if any,  copies  of all
such  documents proposed to be filed,  which  documents
will  be  subject to the review of each Selling  Holder
(if requested  by such Selling Holder), the Initial
Purchasers, the Special Counsel and such Managing
Underwriters, and the Company  shall not file any such
Registration  Statement or
amendment  thereto  or  any  Prospectus  or  any
supplement thereto  to                            which
the  Holders  of  a  majority   of                the
Registrable   Securities  covered   by   such
Registration
Statement,  the  Initial Purchasers or the  Special
Counsel shall reasonably object in writing within five
Business Days after  the receipt thereof.  In addition,
the Company  shall use  its  best  efforts  to reflect
in each  such  document referenced  in  this paragraph
so filed with  the  SEC  such comments as the Initial
Purchasers, Special Counsel and  the Managing
Underwriters, if any, may propose.

           (b)   Subject to Section 2(c), prepare  and
file with  the  SEC such amendments and post-effective
amendments to  each Registration Statement as may be
necessary to  keep such  Registration Statement
continuously effective for  the applicable period
specified in Section 2; cause the  related Prospectus
to be  supplemented by any required  Prospectus
supplement, and as so supplemented to be filed pursuant
to Rule 424 (or any similar provisions then in force)
under the Securities  Act  and  comply  with  the
provisions of  the Securities  Act  with  respect to
the disposition  of  all securities covered by such
Registration Statement during the applicable period in
accordance with the intended methods or disposition
by the  sellers  thereof  set  forth  in  such
Registration  Statement as so amended or such Prospectus
as
so  supplemented.   The Company shall ensure  that  (i)
any Shelf  Registration  and  any  amendment  thereto
and any
Prospectus  forming  a  part thereof and  any  amendment
or
supplement  thereto complies in all material  respects
with the  Act and the rules and regulations thereunder,
(ii)  any Shelf Registration and any amendment thereto
does not,  when it  becomes
effective,  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 light of the circumstances under
which they were made,  not misleading and (iii) any
Prospectus forming  part of  any  Shelf Registration,
and any amendment or supplement to  such Prospectus,
does not include an untrue statement or a  material fact
or omit to state a material fact  necessary in order to
make the statements therein, in the light of the
circumstances under which they were made, not
misleading.

          (c)   Notify the Holders, the Initial
Purchasers, the  Special Counsel and the Managing
Underwriters, if  any, promptly, and (if requested by
any such person) confirm such notice  in  writing, (i)
when a Prospectus,  any  Prospectus supplement,
a Registration Statement or  a  post-effective
amendment  to a Registration Statement has been  filed
with the  SEC,  and, with respect to a Registration
Statement   or
any  post-effective  amendment, when  the  same  has
become effective;  (ii)  of any request by the  SEC  or
any  other federal  or                            state
governmental authority for amendments             or
supplements   to   a  Registration  Statement   or
related
Prospectus  or  for  additional information,  (iii)  of
the issuance by  the  SEC  or  any  other  federal  or
state
governmental  authority  of any stop  order  suspending
the effectiveness of a Registration Statement or the
initiation or  threatening of any proceedings for that
purpose, (iv) of the  receipt by the Company of any
notification with respect to  the  suspension of the
qualification or  exemption  from qualification of any
of the Registrable Securities for  sale in  any
jurisdiction or the initiation or threatening of any
proceedings
for such purpose, (v) of the existence  of  any
fact or happening of any event which makes any statement
of
a  material  fact in such Registration Statement or
related
Prospectus  or  any document incorporated or  deemed  to
be incorporated  therein  by reference untrue  or  which
would require  the  making  of  any changes  in  the
Registration Statement  or Prospectus in order 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, 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, in the light of the circumstances under which
they were made,  not  misleading,  and  (vi)  of  the
Company's determination   that  a  post-effective
amendment   to a Registration Statement would be
appropriate.
         (d)  Use its best efforts to obtain the
withdrawal of  any order suspending the effectiveness of
a Registration Statement,  or  the  lifting  of  any
suspension of                                       the
qualification (or exemption from qualification)  of  any
of the Registrable Securities for sale in any
jurisdiction,  at the earliest possible moment.
          (e)  If requested by the Initial Purchasers or
the Managing  Underwriters, if any, or the Holders of a
Majority of  the  Registrable  Securities being  sold,
(i)  promptly incorporate  in  a  Prospectus supplement
or post-effective amendment to Registration Statement
such information as  the Initial
Purchaser,  the  Special  Counsel,  the
Managing

agree should  be  included  therein, and (ii)  make  all
required filings of such Prospectus supplement or such
post-effective amendment  as  soon  as practicable after
the  Company  has received  notification  of  the
matters proposed         to
be
incorporated in such Prospectus supplement or post
effective amendment.

         (f)  Furnish to each Selling Holder (if
requested by  such  Selling Holder), the Special
Counsel, the  Initial Purchasers,  and each Managing
Underwriter, if any,  without charge,  at  least  one
conformed copy of the  Registration Statement or
Statements and any amendment thereto, including
financial  statements but excluding schedules, all
documents incorporated  or deemed  to  be  incorporated
therein
by
reference and all exhibits.

           (g)   Deliver to each Selling Holder, the
Special Counsel,
the   Initial  Purchasers   and   each
Managing
Underwriter,  if  any, in connection with  any  offering
of Registrable  Securities, without charge, as many
copies  of the  Prospectus or Prospectuses relating to
such Registrable Securities (including each preliminary
prospectus)  and  any amendment   or  supplement
thereto as  such  persons
may reasonably request; and the Company hereby consents
to the use  of  such  Prospectus  or each amendment  or
supplement thereto  by  each  of  the  Selling Holders
of Registrable Securities and the Underwriters, if any,
in connection  with any  offering and sale of the
Registrable Securities covered by such Prospectus or any
amendment or supplement thereto.

          (h)   Prior to any public offering of
Registrable Securities,  to  register or qualify or
cooperate  with  the Selling Holders, the Managing
Underwriters, if any, and  the Special  Counsel  in
connection with  the  registration  or qualification
(or exemption  from  such  registration
or
qualification) of such Registrable Securities for offer
and
sale   under  the  securities  or  Blue  Sky  laws  of
such
jurisdictions within the United States as any Selling
Holder or Managing 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 or
advisable to  enable the  disposition  in such
jurisdictions of  the  Registrable Securities covered by
the applicable Registration Statement, provided,  that
the  Company will not be  required  to  (i) qualify
generally to do business in any jurisdiction  where it
is not then so qualified (ii) take any action that would
subject  it  to general service of process in  suits  or
to taxation  in any such jurisdiction where it is not
then  so subject.

           (i)  Cause the Registrable Securities covered
by the  applicable Registration Statement to be
registered with or  approved by such other governmental
agencies in addition to the SEC or authorities within
the United States as may be necessary to enable the
Selling Holder or Holders thereof or the   Managing
Underwriters,  if  any, to  consummate  the disposition
of such Registrable Securities.
           (j)  During the Effectiveness Period (subject
to the  provisions  of  Section  2(c)),  immediately
upon the existence  of any fact or the occurrence of any
event as  a result  of which a Registration Statement
shall contain  any untrue  statement of a material fact
or omit to  state  any material fact required to be
stated therein or necessary  to make  the  statements
therein, in light of the circumstances under  which they
were made, not misleading, or a Prospectus shall
contain  any untrue statement of a material  fact  or
omit  to  state  any material fact required  to  be
stated therein or necessary to make the statements
therein, in  the light of the circumstances under which
they were made,  not misleading,  promptly  prepare  and
file  a  posteffective amendment to each Registration
Statement or a supplement  to the  related Prospectus or
any document incorporated therein by reference or file
any other required document (such as  a Current  Report
on Form 8K) that would be incorporated  by reference
into  the Registration  Statement  so  that  the
Registration Statement  shall  not  contain   any
untrue statement or a material fact or omit to state any
material fact required to be stated therein or necessary
to make  the statements   therein  not  misleading,  in
light   of the
circumstances under which they were made, and  so  that
the Prospectus  will  not  contain any  untrue
statement of  a material fact or omit to state any
material fact or omit  to state  any  material fact
required to be stated therein  or necessary  to make the
statements therein, in the  light  of the
circumstances  under  which  they were   made,
not misleading, as thereafter delivered to the
purchasers of the Registrable  Securities being sold
thereunder,  and in  the case
of  a  posteffective  amendment  to  a  Registration
Statement  use  its  best efforts  to  cause  it  to
become effective as soon as practicable.

          (k)  Enter into such agreements (including, in
the event of an Underwritten Offering, an underwriting
agreement in form, scope and substance as is customary
in Underwritten Offerings)  and  take all such other
actions in  connection therewith  (including, in the
event of an the  Underwritten Offering,   those
reasonably  requested
by  the   Managing
Underwriters,  if any, or the Holders of a Majority  of
the Registrable  Securities being sold) in order to
expedite  or
facilitate  the  disposition of such Registrable
Securities and  in  such  connection, whether or  not
an underwriting agreement  is  entered into, and if the
registration  is
an underwritten registration, (i) make such
representations and warranties to the Holders of such
Registrable Securities and the underwriters with respect
to the business of the Company and its subsidiaries, the
Registration Statement, Prospectus and   documents
incorporated  by   reference   or   deemed incorporated
by reference, if any, in each case,  in  form, substance
and scope as are customarily made by  issuers
to underwriters in underwritten offerings and confirm
the same if  and  when requested; (ii) use its
reasonable efforts  to
obtain  opinions  of  counsel to  the  Company  and
updates thereof  (which  counsel and opinions (in  form,
scope  and substance) shall be reasonably satisfactory

and the Holders  of  a majority of the Registrable
Securities being sold) addressed to each of the
underwriters covering the matters customarily covered in
opinions requested in underwritten offerings  and such
other matters as may be reasonably requested  by  such
Special  Counsel and Managing Underwriters;  (iii)  use
its reasonable efforts  to obtain "cold  comfort"
letters  and updates thereof  from  the  independent
certified   public accountants  of  the Company (and, if
necessary,  any other certified  public  accountants  of
any  subsidiary of  the Company  or any business
acquired or to be acquired  by  the Company  for  which
financial statements and financial  data are,  or  are
required to be, included in the  Registration
Statement),  addressed to each of the Managing
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, and  (iv) deliver such documents
and certificates as may be reasonably requested  by  the
Holders of a majority of the Registrable Securities
being sold, the Special Counsel and the  Managing
Underwriters, if any, to evidence the continued validity
of the  representations and warranties of the Company
and its subsidiaries  made  pursuant to  clause  (i)
above and   to
evidence  compliance with any customary conditions
contained in  the  underwriting agreement or other
agreement  entered into  by  the  Company.  The above
shall  be  done  at  each closing under such
underwriting or similar agreement as  and to the extent
required thereunder.

            (1)    Make  available  for  inspection   by
a
representative  of  the  Holders of  Registrable
Securities being  sold, any Managing Underwriter
participating  in  any disposition  of  Registrable
Securities,  if  any,  and  any attorney  or accountant
retained by such Selling Holders
or underwriter,   financial   and  other   records,
pertinent
corporate  documents and properties of the Company  and
its subsidiaries,  and  cause the executive officers,
directors and  employees of the Company and its
subsidiaries to supply all   information   reasonably
requested   by   any                                such
representative, Managing Underwriter, attorney or
accountant in connection with such disposition;
provided, however, that any  information  that  is
reasonable  and in  good  faith designated by the
Company in writing as confidential at  the time   of
delivery  of  such information  shall  be
kept confidential by such persons, unless (i) disclosure
of such information is required by court or
administrative order          or
is   necessary   to  respond  to  inquiries  of
regulatory authorities, (ii) disclosure of such
information is required by  law  (including any
disclosure requirements pursuant
to federal securities laws in connection with the filing
of any Registration Statement or the use of any
prospectus referred
to  in  this  Agreement),  (iii)  such  information
becomes generally available to the public other than as
a result  of 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.

            (m)   Comply  with  all  applicable  rules
and
regulations  of  the SEC in all material respects  and
make generally
available   to   its  securityholders   earnings
statements  (which  need  not  be  audited)  satisfying
the
provisions of Section 11(a) of the Securities Act  and
Rule 158  thereunder (or any similar rule promulgated
under  the Securities Act) no later than 45 days after
the end  of  any 12-month  period (or 90 days after the
end of any  12-month period  if
such period is a fiscal year) (i) commencing  at
the   end   of  any  fiscal  quarter  in  which
Registrable
Securities  are sold to underwriters in firm  commitment
or
best  efforts underwritten offering and (ii) if not sold
to underwriters  in such an offering, commencing on  the
first day  of  the  first fiscal quarter of the Company
commencing after  the effective date of a Registration
Statement, which statements shall cover said 12-month
periods.

            (n)   Cooperate  with  the  Selling  Holders
of Registrable Securities, the Initial Purchasers, the
Special Counsel and the Managing Underwriters, if any,
to facilitate the   timely   preparation  and  delivery
of
certificates representing  Registrable Securities  to
be sold  and  not bearing any restrictive legends; and
enable such Registrable Securities
to  be in such denominations and  registered  in
such names as the Holders may request.

           (o)  Not later than the effectiveness date of
any Registration Statement hereunder, provide a CUSIP
number for the    Registrable   Securities   registered
under    such Registration  Statement, and provide the
Trustee  under  the Indenture  and the transfer agent
for the Common Stock  with printed  certificates for the
Registrable  Securities  which are in a form eligible
for deposit with The Depository Trust Company.
           (p)  Cause all shares of Common Stock covered
by the  Registration Statement to be listed on, each
securities exchange  or quotation system on which the
Company's  Common Stock  is  then listed or quoted no
later than the date  the Registration  Statement  is
declared  effective,  and,
in
connection therewith, to the extent applicable, to make
such findings  under  the Exchange Act (e.g.,  the
filing of  a Registration Statement on Form 8-A) and to
have such filings declared effective thereunder.

           (q)   Cooperate and assist in any filing
required to  be  made  with  the National Association
of Securities Dealers, Inc.

          (r)  Cause the Indenture to be qualified under
the TIA,  and,
in  connection  therewith,  cooperate  with  the
Trustee and the Holders, the Initial Purchasers, the
Special Counsel  and  the Managing Underwriters, if any,
to  effect such  changes to the Indenture 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 documents as may  be  required  to effect  such
changes and  all other  forms  and  documents required
to be filed with the SEC to enable such  Indenture
to be so qualified in a timely manner.
     The Company may require each Holder of securities
to be sold  pursuant to any Registration Statement to
furnish  to the  Company such information regarding the
Holder  and  the distribution of such securities as the
Company may from time to                           time
reasonably  require  for   inclusion               in
such
Registration  Statement.  Any Holder who  fails  to
provide such   information  shall  not  be  entitled  to
use  the
Prospectus.

     4.    Registration  Expenses.  All  fees  and
expenses
incident  to the Company's obligations under this
Agreement shall  be
borne by the Company whether or not  any  of  the
Registration  Statements become effective.   Such  fees
and expenses
shall include,  without  limitation,
(i) all
registration and filing fees (including, without
limitation, fees  and
expenses with respect to filings required  to  be
made  with  the National Association of Securities
Dealers, Inc.),
(ii) printing       expenses   (including,   without
limitation,   expenses   of   printing
certificates for
Registrable  Securities in a form eligible for
deposit with The Depository Trust Company and of
printing Prospectuses if the  printing  of
Prospectuses is
requested by  the  Special Counsel,  the  Initial
Purchasers, the Managing Underwriters or  the  holders
of a Majority of the Registrable Securities included  in
any Registration Statement), (iii)  reasonable fees  and
disbursements of counsel for the Company  and  the
Special Counsel  in connection with the Shelf
Registration (provided that the Company shall not be
liable for the fees and  expenses of more than one
separate firm for all parties (other  than  the Company)
participating in any transaction hereunder),
and (iv)  fees  and  disbursements   of
all independent  certified  public accountants  referred
to in Section  3(k)(iii)  hereof (including the
expenses  of any special  audit  and "cold comfort"
letters  required by  or incident  to  such
performance).  In addition,  the Company shall pay the
fees and expenses incurred in connection  with the
listing or quotation of the securities to be registered
on  any  securities exchange or quotations system  on
which similar securities issued by the Company are then
listed and the  fees         and expenses  of any
person,  including  special
experts, retained by the Company.

     5.   Indemnification.

           (a)  Indemnification by the Company.  The
Company shall   indemnify  and  hold  harmless  each
Holder,  the
directors,  officers,  employees and  agents  of  each
such Holder and each person, if any, who controls any
such Holder (within  the meaning of either Section 15 of
the Securities Act  or Section 20 of the Exchange Act)
from and against all losses, liabilities, damages and
expenses (including without limitation, any legal or
other expenses reasonably  incurred in  connection  with
defending or investigating  any  such action or claim)
(collectively, "Losses"), arising out of or based  upon
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
arising  out of  or  based  upon any  omission  or
alleged omission to  state therein a material fact
required  to  be stated therein or necessary to make the
statements  therein not misleading, in light of the
circumstances  under  which they  were made, except
insofar as such Losses arise out of or  are  based upon
the information relating to  any Holder furnished
to the Company in writing by any Holder expressly
for  use  therein.   The Company shall also  indemnify
each underwriter, their officers and directors, and
each person who  controls such person (within the
meaning of Section          15
of  the Securities Act or Section 20 of the Exchange Act
to
the  same  extent and with the same limitations as
provided above with respect to the indemnification of
the Holders       or
Registrable Securities.

           (b)   Indemnification  by Holder  of
Registrable Securities.   Each Holder, agrees severally
and not  jointly to  indemnify and hold harmless the
Company, its  directors, its  officers  who  sign a
Registration Statement  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
Exchange Act), from and against all losses arising  out
of or  based  upon any untrue statement of a material
fact contained  in  any  Registration  Statement,
Prospectus or
arising out of or based upon any omission of a material
fact required  to  be  stated therein or necessary  to
make  the statements   therein  not  misleading,  in
light   of     the
circumstances under which they were made, to the extent,
but only  to  the extent, that such untrue statement or
omission is  contained in any information relating to
such Holder         so
furnished in writing by such Holder to the Company
expressly for use in such Registration Statement or
Prospectus.  In no event   shall  the  liability  of
any Selling  Holder
of
Registrable  Securities hereunder be greater in amount
than the  dollar  amount of the proceeds received by
such Holder upon  the sale of the Registrable Securities
giving rise    to
such indemnification obligation.

           (c)  Conduct of Indemnification Proceedings.
In
case    any    proceeding   (including   any
governmental
investigation) shall be instituted involving any  person
in
respect of which indemnity may be sought pursuant to
either of  the two   preceding  paragraphs,  such
person (the
"indemnified  party")  shall  promptly  notify  the
person against whom such indemnity may be sought (the
"indemnifying party") in writing, but failure so to
notify an indemnifying party  shall  not relieve such
indemnifying party  from  any liability  hereunder  to
the extent  it  is  not  materially prejudiced  as  a
result thereof.  The indemnifying  party, upon  request
of the indemnified party, shall retain counsel
satisfactory  to the  indemnified party  to  represent
the indemnified party and any others the indemnifying
party  may designate in  such proceeding and shall pay
the  fees  and disbursements  of  such counsel related
to such proceeding. In any such proceeding, any
indemnified party shall have the right  to  retain its
own counsel, but the fees and expenses of  such counsel
shall be at the expense of such indemnified party
unless (i) the indemnifying party and the indemnified
party  shall have mutually agreed to the retention  to
such counsel  (ii)  the named  parties to  any  such
proceeding (including   any impleaded  parties)  include
both
the
indemnifying   party   and   the   indemnified   party
and
representation of both parties by the same counsel would
be
inappropriate due to actual or potential differing
interests between them, or (iii) the indemnifying party
shall not have employed  counsel satisfactory to the
indemnified  party
to
represent  the  indemnified party within a  reasonable
time after   notice  of  commencement  of  the  action.
It             is
understood that the indemnifying party shall not, in
respect of the legal expenses or any indemnified party
in connection with  any  proceeding  or related
proceedings in  the  same jurisdiction,  be liable for
the fees and expenses  of  more than  one  separate firm
(in addition to any local  counsel)
for  all  indemnified  parties under Section  5(a)  or
5(b)
hereof  who  are parties to such proceeding or
proceedings, and  that all such fees and expenses shall
be reimbursed       as
they  are  incurred.  The indemnifying party  shall  not
be
liable for any settlement of any proceeding effected
without its written consent, but if settled with such
consent or   if
there   be   a   final  judgment  for  the  plaintiff,
the
indemnifying party agrees to indemnify the indemnified
party from  and  against any loss or liability by reason
of  such
settlement  or  judgment.   Notwithstanding  the
foregoing
sentence,  if  at any time an indemnified party  shall
have requested an indemnifying party to reimburse the
indemnified party  for  fees and expenses of counsel as
contemplated   by
the  second  and  third  sentences of this  paragraph,
such indemnifying  party agrees that it shall be liable
for  any
settlements  of any proceeding effected without its
written
consent if (i) such settlement is entered into more than
45
days  after  receipt  by  such  indemnifying  party  of
the
aforesaid request and (ii) such indemnifying party shall
not have  reimbursed  the indemnified party in
accordance with such  request  prior  to the date 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.

            (d)    Contribution.   If  the
indemnification provided  for  in  this  Section  5  is
unavailable  to                             an
indemnified  party  under Section 5(a)  or  5(b)  hereof
in
respect  of  any  Losses  or is insufficient  to  hold
such indemnified                              party
harmless,   then   each                  applicable
indemnifying party, in lieu of indemnifying such
indemnified party,  shall  contribute to the amount paid
or  payable  by
such  indemnified party as a result of such Losses,  (i)
in
such  proportion as is appropriate to reflect  the
relative
benefits  received by the indemnifying party or  parties
on
the  one  hand and the indemnified party or parties  an
the
other hand 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 indemnifying party or
parties on the one hand and of the  indemnified  party
or parties on  the  other
hand     in
connection with the statements or omissions that
resulted in such  Losses,  as  well  as  any  other
relevant equitable considerations.  Benefits received by
the Company  shall                         be
deemed  to  be  equal  to the total net  proceeds
from the initial  placement  of the Notes pursuant
to  the Purchase
Agreement.   Benefits  received by  the  Initial
Purchasers
shall  be deemed to be equal to the total purchase
discounts and  commissions received by them pursuant
to the   Purchase
Agreement  and benefits received by any other Holders
shall be  deemed  to  be  equal to the value  of
receiving  Notes registered  under the Securities
Act. Benefits received                           by
any  underwriter shall be deemed to be equal  to  the
total underwriting discounts and commissions, as set
forth on  the cover  page  of  the  Prospectus  forming
a  part of         the
Registration Statement which resulted in such  Losses.
The
relative  fault  of  the Holders on the  one  hand  and
the
Company  on the other hand 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 Holders or by the Company
and the  parties' relative  intent,  knowledge,  access
to information                                   and
opportunity   to  correct  or  prevent  such  statement
or
omission.  The Holders' respective obligations to
contribute pursuant to this paragraph are several in
proportion to  the respective number of Registrable
Securities they  have  sold pursuant to a Registration
Statement, and not joint.

   The  parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section
5(d) were determined by pro rata allocation or by any
other method  or allocation  that  does not take into
account  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
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 this Section  5(d),
an
indemnifying  party that is a Selling Holder of
Registrable Securities shall not be required to
contribute any amount in excess  of the amount by which
the total price at which  the Registrable Securities sold
by such indemnifying  party  and distributed to the
public were offered to the public exceeds the  amount of
any damages which such indemnifying party 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  indemnity, contribution and expense
reimbursement obligations of the Company hereunder shall
be in addition to any  liability  the  Company may
otherwise  have  hereunder, under the Purchase Agreement
or otherwise.
     The indemnity and contribution provisions contained
in this Section 5 shall remain operative and in full
force and effect  regardless of (i) any termination of
this Agreement, (ii) any investigation made by or on
behalf of any Holder or any  person  controlling any
Holder,  or the  Company,  its officers or directors or
any person controlling the  Company and  (iii)  the  sale
of any Registrable Securities  by  any Holder.
     6.   Information Requirements.
           (a)   The Company shall file the reports
required to  be filed by it under the Securities Act and
the Exchange Act,  and if at any time the Company is not
required to file such  reports,  it will, upon the
request of any  Holder  of Registrable   Securities,
make publicly  available   other information so long as
necessary to permit sales pursuant to Rule  144  and
Rule 144A under the  Securities  Act.                 The
Company  further covenants that it will cooperate  with
any
Holder  of  Registrable  Securities and  take  such
further reasonable  action  as any Holder of Registrable
Securities may   reasonably  request  (including,
without limitation, making  such  reasonable
representations as any such  Holder may  reasonably
request), all to the extent  required  from time  to
enable such Holder to sell Registrable  Securities
without  registration under the Securities  Act  within
the
limitation of the exemptions provided by Rule 144  and
Rule 144A   under   the  Securities  Act. Notwithstanding
the
foregoing,  nothing  in this Section 6 shall  be  deemed
to require the Company to register any of its securities
under any section of the Exchange Act.

           (b)   The Company shall file the reports
required to  be  filed by it under the Exchange Act and
shall  comply with all other requirements set forth in
the instructions to the  appropriate SEC Registration
Statement form  permitting registration of the
Registrable Securities for resale by the Holders thereof
in the manner or manners designated by them.
     7.   Miscellaneous.
           (a)   Remedies.  In the event of a breach by
the Company of its obligations under this Agreement, each
Holder of  Registrable Securities, in addition to being
entitled to exercise  all rights granted by law,
including recovery  of damages,  will  be entitled to
specific performance  of  its rights  under  this
Agreement.   The Company  agrees  that monetary damages
would not be adequate compensation for  any loss
incurred  by reason or a breach by it of  any  of  the
provisions of this Agreement and hereby further agrees
that, in  the  event of  any action for specific
performance  in respect  of such breach, it shall waive
the defense  that  a remedy at law would be adequate.
           (b)  No Conflicting Agreements.  The Company
has not  entered,  as of the date hereof and shall  not,
on  or after  the  date of this Agreement, enter into any
agreement with  respect  to  its securities which
conflicts  with  the rights  granted to the Holders of
Registrable Securities  in this  Agreement.  The Company
represents and  warrants  that the  rights granted to the
Holders of Registrable Securities hereunder do not in any
way conflict with the rights granted to  the holders of
the Company's securities under any  other agreements.
           (c)   Amendments and Waivers.  The provisions
of this  Agreement, including the provisions of this
sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions
hereof may not be given,  unless the Company has obtained
the written  consent of Holders of a Majority of the then
outstanding Registrable Securities.   Notwithstanding the
foregoing,  a  waiver  or consent to depart from the
provisions hereof with respect to a  matter that relates
exclusively to the rights of  holders of  Registrable
Securities whose securities are  being  sold pursuant  to
a  Registration Statement and  that  does  not directly
or indirectly affect the rights of other Holders of
Registrable Securities may be given by Holders of at
least a majority  of the Registrable Securities being
sold  by such Holders; provided, that the provisions of
this sentence  may not
be  amended,  modified,  or  supplemented  except
in
accordance with the provisions of the immediately
preceding sentence.

Initial Purchasers or subsequent holders of Registrable
Securities if such subsequent holders are deemed to be
such affiliates solely  by  reason of  their  holdings
of  such Registrable  Securities) shall not be counted
in determining whether such consent or approval was
given by the Holders of such required percentage.

           (g)   Successors  and Assigns.   Any  person
who purchases   any  Registrable  Securities  from  an
Initial Purchaser shall be deemed, for purposes of this

of any Registrable Securities.
