2. EXCHANGE OFFER

     (a)  Unless the Exchange Offer would not be permitted by applicable laws or

          Subsidiary Guarantor to) (i)


                                        4



          use commercially reasonable efforts to prepare and file with the SEC
          promptly after the date hereof and by the Filing Date, a registration
          statement (the "Exchange Registration Statement") on an appropriate
          form under the Securities Act with respect to an offer (the "Exchange
          Offer") to the Holders of Notes to issue and deliver to such Holders,
          in exchange for the Notes, a like principal amount of Exchange Notes,
          (ii) use commercially reasonable efforts to cause the Exchange
          Registration Statement to become effective as promptly as practicable
          after the filing thereof and on or before the Effectiveness Date,
          (iii) use its best efforts to keep the Exchange Registration Statement
          effective until the consummation of the Exchange Offer in accordance
          with its terms, and (iv) commence the Exchange Offer and use its best
          efforts to issue, on or prior to 30 Business Days after the date on
          which the Exchange Registration Statement is declared effective,
          Exchange Notes in exchange for all Notes tendered prior thereto in the
          Exchange Offer. The Exchange Offer shall not be subject to any
          conditions, other than that the Exchange Offer does not violate
          applicable law or any applicable interpretation of the staff of the
          SEC.

     (b)  The Exchange Notes shall be issued under, and entitled to the benefits
          of, (i) the Indenture or a trust indenture that is identical to the
          Indenture (other than such changes as are necessary to comply with any
          requirements of the SEC to effect or maintain the qualifications
          thereof under the TIA) and (ii) the Collateral Agreements.

     (c)  Interest on the Exchange Notes and Private Exchange Notes will accrue
          (i) from the later of (A) the last interest payment date on which
          interest was paid on the Notes surrendered in exchange therefor, or
          (B) if the Notes are surrendered for exchange on a date in a period
          which includes the record date for an interest payment date to occur
          on or after the date of such exchange and as to which interest was
          paid, the date of such interest payment date; or (ii) if no interest
          has been paid on the Notes, from the Closing Date. Each Exchange Note
          and Private Exchange Note shall bear interest at the rate set forth
          thereon; provided, that interest with respect to the -------- period
          prior to the issuance thereof shall accrue at the rate or rates borne
          by the Notes from time to time during such period.

     (d)  The Company may require each Holder as a condition to participation in
          the Exchange Offer to represent (i) that any Exchange Notes received
          by it will be acquired in the ordinary course of its business, (ii)
          that at the time of the commencement and consummation of the Exchange
          Offer such Holder has not entered into any arrangement or
          understanding with any Person to participate in the distribution
          (within the meaning of the Securities Act) of the Exchange Notes in
          violation of the provisions of the Securities Act, (iii) that if such
          Holder is an "affiliate" of the Company within the meaning of Rule 405
          of the Securities Act, it will comply with the registration and
          prospectus delivery requirements of the Securities Act to the extent
          applicable to it, (iv) if such Holder is not a broker-dealer, that it
          is not engaged in, and does not intend to engage in, the distribution
          of the Notes and (v) if such Holder is a Participating Broker-Dealer
          (as defined


                                        5



          below), that it will deliver a Prospectus in connection with any
          resale of the Exchange Notes.

     (e)  The Company shall (and shall cause each Subsidiary Guarantor to)
          include within the Prospectus contained in the Exchange Registration
          Statement a section entitled "Plan of Distribution" reasonably
          acceptable to the Initial Purchaser which shall contain a summary
          statement of the positions taken or policies made by the staff of the
          SEC with respect to the potential "underwriter" status of any
          broker-dealer that is the beneficial owner (as defined in Rule 13d-3
          under the Exchange Act) of Exchange Notes received by such
          broker-dealer in the Exchange Offer for its own account in exchange
          for Notes that were acquired by it as a result of market-making or
          other trading activity (a "Participating Broker-Dealer"), whether such
          positions or policies have been publicly disseminated by the staff of
          the SEC or such positions or policies, in the judgment of the Initial
          Purchaser, represent the prevailing views of the staff of the SEC.
          Such "Plan of Distribution" section shall also allow, to the extent
          permitted by applicable policies and regulations of the SEC, the use
          of the Prospectus by all Persons subject to the prospectus delivery
          requirements of the Securities Act, including, to the extent so
          permitted, all Participating Broker-Dealers, and include a statement
          describing the manner in which Participating Broker-Dealers may resell
          the Exchange Notes. The Company shall use its best efforts to keep the
          Exchange Registration Statement effective and to amend and supplement
          the Prospectus contained therein, in order to permit such Prospectus
          to be lawfully delivered by all Persons subject to the prospectus
          delivery requirements of the Securities Act for such period of time as
          such Persons must comply with such requirements in order to resell the
          Exchange Notes; provided that such period shall not exceed the lesser
          of 180 days and the date on which all persons subject to the
          prospectus delivery requirements of the Securities Act have sold all
          Exchange Notes held by them (the "Applicable Period").

     (f)  If, upon consummation of the Exchange Offer, the Initial Purchaser
          hold any Notes acquired by them and having the status of an unsold
          allotment in the initial distribution, the Company (upon the written
          request from the Initial Purchaser) shall, simultaneously with the
          delivery of the Exchange Notes in the Exchange Offer, issue and
          deliver to the Initial Purchaser, in exchange (the "Private Exchange")
          for the Notes held by the Initial Purchaser, a like principal amount
          of Notes that are identical to the Exchange Notes except for the
          existence of restrictions on transfer thereof under the Securities Act
          and securities laws of the several states of the United States (the
          "Private Exchange Notes") (and which are issued pursuant to the same
          indenture as the Exchange Notes). The Private Exchange Notes shall
          bear the same CUSIP number as the Exchange Notes.

     (g)  In connection with the Exchange Offer, the Company shall (and shall
          cause each Subsidiary Guarantor to):

          (i)  mail to each Holder a copy of the Prospectus forming part of the
               Exchange Registration Statement, together with an appropriate
               letter of transmittal


                                        6



               that is an exhibit to the Exchange Registration Statement, and
               any related documents;

          (ii) keep the Exchange Offer open for not less than 20 Business Days
               after the date notice thereof is mailed to the Holders (or longer
               if required by applicable law);

          (iii) utilize the services of a depository for the Exchange Offer with
               an address in the Borough of Manhattan, the City of New York,
               which may be the Trustee or an affiliate thereof;

          (iv) permit Holders to withdraw tendered Registrable Notes at any time
               prior to the close of business, New York time, on the last
               Business Day on which the Exchange Offer shall remain open; and

          (v)  otherwise comply in all material respects with all applicable
               laws.

     (h)  As soon as practicable after the close of the Exchange Offer or the
          Private Exchange, as the case may be, the Company shall (and shall
          cause each Subsidiary Guarantor to):

          (i)  accept for exchange all Registrable Notes validly tendered
               pursuant to the Exchange Offer or the Private Exchange, as the
               case may be, and not validly withdrawn;

          (ii) deliver to the Trustee for cancellation all Registrable Notes so
               accepted for exchange; and

          (iii) cause the Trustee to authenticate and deliver promptly to each
               Holder tendering such Registrable Notes, Exchange Notes or
               Private Exchange Notes, as the case may be, equal in principal
               amount to the Notes of such Holder so accepted for exchange.

     (i)  The Exchange Notes and the Private Exchange Notes may be issued under
          (i) the Indenture or (ii) an indenture identical to the Indenture
          (other than such changes as are necessary to comply with any
          requirements of the SEC to effect or maintain the qualification
          thereof under the TIA), which in either event will provide that the
          Exchange Notes will not be subject to the transfer restrictions set
          forth in the Indenture, that the Private Exchange Notes will be
          subject to the transfer restrictions set forth in the Indenture, and
          that the Exchange Notes, the Private Exchange Notes and the Notes, if
          any, will be deemed one class of security (subject to the provisions
          of the Indenture) and entitled to participate in all the security
          granted by the Company pursuant to the Collateral Agreements and in
          any Subsidiary Guarantee (as such terms are defined in the Indenture)
          on an equal and ratable basis.

     (j)  If: (i) prior to the consummation of the Exchange Offer, the Holders
          of a majority in aggregate principal amount of Registrable Notes
          determines in its or their


                                        7



          reasonable judgment that (A) the Exchange Notes would not, upon
          receipt, be tradeable by the Holders thereof without restriction under
          the Securities Act and the Exchange Act and without material
          restrictions under applicable Blue Sky or state securities laws, or
          (B) the interests of the Holders under this Agreement, taken as a
          whole, would be materially adversely affected by the consummation of
          the Exchange Offer; (ii) applicable interpretations of the staff of
          the SEC would not permit the consummation of the Exchange Offer prior
          to the Effectiveness Date; (iii) subsequent to the consummation of the
          Private Exchange, any Holder of Private Exchange Notes so requests;
          (iv) the Exchange Offer is not consummated within 30 Business Days
          from the date the Exchange Registration Statement was declared
          effective; or (v) in the case of (A) any Holder not permitted by
          applicable law or SEC policy to participate in the Exchange Offer, (B)
          any Holder participating in the Exchange Offer that receives Exchange
          Notes that may not be sold without restriction under state and federal
          securities laws (other than due solely to the status of such Holder as
          an affiliate of the Company within the meaning of the Securities Act)
          or (C) any broker-dealer that holds Notes acquired directly from the
          Company or any of its affiliates and, in each such case contemplated
          by this clause (v), such Holder notifies the Company within six months
          of consummation of the Exchange Offer, then the Company shall promptly
          (and in any event within five Business Days) deliver to the Holders
          (or in the case of an occurrence of any event described in clause (v)
          of this Section 2(j), to any such Holder) and the Trustee notice
          thereof (the "Shelf Notice") and shall as promptly as possible
          thereafter (but in no event more than 45 days after delivery of the
          Shelf Notice) file an Initial Shelf Registration pursuant to Section
          3.

3. SHELF REGISTRATION

     If a Shelf Notice is delivered pursuant to Section 2(j), then this Section
3 shall apply to all Registrable Notes. Otherwise, upon consummation of the
Exchange Offer in accordance with Section 2, the provisions of Section 3 shall
apply solely with respect to (i) Notes held by any Holder thereof not permitted
to participate in the Exchange Offer, (ii) Notes held by any broker-dealer that
acquired such Notes directly from the Company or any of its affiliates and (iii)
Exchange Notes that are not freely tradeable as contemplated by Section 2(j)(v)
hereof, provided in each case that the relevant Holder has duly notified the
Company within six months of the Exchange Offer as required by Section 2(j)(v).

     (a)  Initial Shelf Registration. The Company shall (and shall cause each
          Subsidiary Guarantor to), as promptly as practicable, file with the
          SEC a Registration Statement for an offering to be made on a
          continuous basis pursuant to Rule 415 covering all of the Registrable
          Notes (the "Initial Shelf Registration"). If the Company (and any
          Subsidiary Guarantor) has not yet filed an Exchange Registration
          Statement, the Company shall (and shall cause each Subsidiary
          Guarantor to) file with the SEC the Initial Shelf Registration on or
          prior to the Filing Date and shall use its best efforts to cause such
          Initial Shelf Registration to be declared effective under the
          Securities Act on or prior to the Effectiveness Date. Otherwise, the
          Company shall (and shall cause each Subsidiary Guarantor


                                        8



          to) use its best efforts to file with the SEC the Initial Shelf
          Registration within 30 days of the delivery of the Shelf Notice and
          shall use its best efforts to cause such Shelf Registration to be
          declared effective under the Securities Act as promptly as practicable
          thereafter (but in no event more than 45 days after delivery of the
          Shelf Notice). The Initial Shelf Registration shall be on Form S-1 or
          another appropriate form permitting registration of such Registrable
          Notes for resale by Holders in the manner or manners reasonably
          designated by them (including, without limitation, one or more
          underwritten offerings). The Company and Subsidiary Guarantors shall
          not permit any securities other than the Registrable Notes to be
          included in any Shelf Registration. The Company shall (and shall cause
          each Subsidiary Guarantor to) use its best efforts to keep the Initial
          Shelf Registration continuously effective under the Securities Act
          until the date which is 24 months from the Closing Date (subject to
          extension pursuant to the last sentence of Section 6(w) (the
          "Effectiveness Period"), or such shorter period ending when (i) all
          Registrable Notes covered by the Initial Shelf Registration have been
          sold in the manner set forth and as contemplated in the Initial Shelf
          Registration, (ii) a Subsequent Shelf Registration covering all of the
          Registrable Notes covered by and not sold under the Initial Shelf
          Registration or an earlier Subsequent Shelf Registration has been
          declared effective under the Securities Act or (iii) there cease to be
          any outstanding Registrable Notes.

     (b)  Subsequent Shelf Registrations. If the Initial Shelf Registration or
          any Subsequent Shelf Registration (as defined below) ceases to be
          effective for any reason at any time during the Effectiveness Period
          (other than because of the sale of all of the securities registered
          thereunder), the Company shall (and shall cause each Subsidiary
          Guarantor to) 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 such Shelf
          Registration in a manner to obtain the withdrawal of the order
          suspending the effectiveness thereof, or file (and cause each
          Subsidiary Guarantor to file) an additional "shelf" Registration
          Statement pursuant to Rule 415 covering all of the Registrable Notes
          (a "Subsequent Shelf Registration"). If a Subsequent Shelf
          Registration is filed, the Company shall (and shall cause each
          Subsidiary Guarantor to) 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 Subsequent Shelf Registration
          continuously effective for a period equal to the number of days in the
          Effectiveness Period less the aggregate number of days during which
          the Initial Shelf Registration or any Subsequent Shelf Registration
          was previously continuously effective. As used herein the term "Shelf
          Registration" means the Initial Shelf Registration and any Subsequent
          Shelf Registrations

     (c)  Supplements and Amendments. The Company shall promptly supplement and
          amend any Shelf Registration if required by the rules, regulations or
          instructions applicable to the registration form used for such Shelf
          Registration or if required by the Securities Act.


                                        9



     (d)  Provision of Information. No Holder of Registrable Notes shall be
          entitled to include any of its Registrable Notes in any Shelf
          Registration pursuant to this Agreement unless such Holder furnishes
          to the Company and the Trustee in writing, within 20 days after
          receipt of a written request therefor, such information as the Company
          and the Trustee after conferring with counsel with regard to
          information relating to Holders that would be required by the SEC to
          be included in such Shelf Registration or Prospectus included therein,
          may reasonably request for inclusion in any Shelf Registration or
          Prospectus included therein, and no such Holder shall be entitled to
          Additional Interest pursuant to Section 4 hereof unless and until such
          Holder shall have provided such information.

4. ADDITIONAL INTEREST

     (a)  The Company and each Subsidiary Guarantor acknowledges and agrees that
          the Holders of Registrable Notes will suffer damages if the Company or
          any Subsidiary Guarantor fails to fulfill its material obligations
          under Section 2 or Section 3 hereof and that it would not be feasible
          to ascertain the extent of such damages with precision. Accordingly,
          the Company and the Subsidiary Guarantors agree to pay additional cash
          interest on the Notes ("Additional Interest") under the circumstances
          and to the extent set forth below (each of which shall be given
          independent effect):

          (i)  if (A) neither the Exchange Registration Statement nor the
               Initial Shelf Registration has been filed on or prior to the
               Filing Date or (B) notwithstanding that the Exchange Offer has or
               will be consummated, the Company is required to file a Shelf
               Registration Statement and such Shelf Registration Statement in
               not filed on or prior to the date required under Section 3 of
               this Registration Rights Agreement, then Additional Interest
               shall accrue on the Notes over and above any stated interest at a
               rate of 0.25% per annum of the principal amount of such Notes for
               the first 90 days immediately following the Filing Date, such
               Additional Interest rate increasing by an additional 0.25% per
               annum at the beginning of each subsequent 90-day period;

          (ii) if (A) neither the Exchange Registration Statement nor the
               Initial Shelf Registration is declared effective on or prior to
               the Effectiveness Date or (B) notwithstanding that the Exchange
               Offer has or will be consummated, the Company is required to file
               a Shelf Registration Statement and such Shelf Registration
               Statement is not declared effective by the SEC on or prior to the
               90th day following the date such Shelf Registration Statement was
               filed, then, commencing on the day after either such required
               effective date, Additional Interest shall accrue on the Notes
               over and above any stated interest at a rate of 0.25% per annum
               of the principal amount of such Notes for the first 90 days
               immediately following the Effectiveness Date, such Additional
               Interest rate increasing by an additional 0.25% per annum at the
               beginning of each subsequent 90-day period;


                                       10



          (iii) if (A) the Company (and any Subsidiary Guarantor) has not
               exchanged Exchange Notes for all Notes validly tendered in
               accordance with the terms of the Exchange Offer on or prior to
               the 30th Business Day after the Effectiveness Date or (B) if
               applicable, a Shelf Registration has been declared effective and
               such Shelf Registration ceases to be effective at any time prior
               to the second anniversary of the Closing Date (other than such
               time as all Notes have been disposed of thereunder) and is not
               declared effective again within 30 days, then Additional Interest
               shall accrue on the Notes, over and above any stated interest, at
               a rate of 0.25% per annum of the principal amount of such Notes
               for the first 90 days commencing on (x) the 31st Business Day
               after the Effectiveness Date, in the case of (A) above, or (y)
               the day such Shelf Registration ceases to be effective in the
               case of (B) above, such Additional Interest rate increasing by an
               additional 0.25% per annum at the beginning of each such
               subsequent 90-day period;

          provided, however, that Additional Interest will not accrue under more
          than one of the foregoing clauses (i), (ii) or (iii) at any one time;
          provided further, that the maximum Additional Interest rate on the
          Notes may not exceed at any one time in the aggregate 1.00% per annum;
          and provided further, that (1) upon the filing of the Exchange
          Registration Statement or Initial Shelf Registration (in the case of
          (i) above), (2) upon the effectiveness of the Exchange Registration
          Statement or Initial Shelf Registration (in the case of (ii) above),
          or (3) upon the exchange of Exchange Notes for all Notes tendered (in
          the case of (iii)(A) above), or upon the effectiveness of a Shelf
          Registration which had ceased to remain effective (in the case of
          (iii)(B) above), Additional Interest on the Notes as a result of such
          clause (or the relevant subclause thereof), as the case may be, shall
          cease to accrue.

     (b)  The Company shall notify the Trustee within three Business Days after
          each and every date on which an event occurs in respect of which
          Additional Interest is required to be paid (an "Event Date"). Any
          amounts of Additional Interest due pursuant to clause (a)(i), (a)(ii)
          or (a)(iii) of this Section 4 will be payable in cash, on the dates
          and in the manner provided in the Indenture and whether or not any
          cash interest would then be payable on such date, commencing with the
          first such semi-annual date occurring after any such Additional
          Interest commences to accrue. The amount of Additional Interest will
          be determined by multiplying the applicable Additional Interest rate
          by the principal amount of the Notes, multiplied by a fraction, the
          numerator of which is the number of days such Additional Interest rate
          was applicable during such period (determined on the basis of a
          360-day year comprised of twelve 30-day months and, in the case of a
          partial month, the actual number of days elapsed), and the denominator
          of which is 360.

5. HOLD-BACK AGREEMENTS

     The Company agrees that it will not effect any public or private sale or
distribution (including a sale pursuant to Regulation D under the Securities
Act) of any securities the same as or similar to those covered by a Registration
Statement filed pursuant to Section 2 or 3 hereof


                                       11



(other than Additional Notes (as defined in the Indenture) issued under the
Indenture), or any securities convertible into or exchangeable or exercisable
for such securities, during the 10 days prior to, and during the 90-day period
beginning on, the effective date of any Registration Statement filed pursuant to
Sections 2 and 3 hereof unless the Holders of a majority of the aggregate
principal amount of the Registrable Notes to be included in such Registration
Statement consent, if the managing underwriter thereof (if any) so requests in
writing.

6. REGISTRATION PROCEDURES

     In connection with the filing of any Registration Statement pursuant to
Sections 2 or 3 hereof, the Company shall (and shall cause each Subsidiary
Guarantor to) effect such registrations to permit the sale of such securities
covered thereby in accordance with the intended method or methods of disposition
thereof, and pursuant thereto and in connection with any Registration Statement
filed by the Company hereunder, the Company shall (and shall cause each
Subsidiary Guarantor to):

     (a)  Prepare and file with the SEC as soon as practicable after the date
          hereof but in any event on or prior to the Filing Date, the Exchange
          Registration Statement or if the Exchange Registration Statement is
          not filed because of the circumstances contemplated by Section 2(j), a
          Shelf Registration as prescribed by Section 3, and use its
          commercially reasonable efforts to cause each such Registration
          Statement to become effective and remain effective as provided herein;
          provided that, if (1) a Shelf Registration is filed pursuant to
          Section 3 or (2) a Prospectus contained in an Exchange Registration
          Statement filed pursuant to Section 2 is required to be delivered
          under the Securities Act by any Participating Broker-Dealer who seeks
          to sell Exchange Notes during the Applicable Period relating thereto,
          before filing any Registration Statement or Prospectus or any
          amendments or supplements thereto the Company shall (and shall cause
          each Subsidiary Guarantor to), if requested, furnish to and afford the
          Holders of the Registrable Notes to be registered pursuant to such
          Shelf Registration Statement, each Participating Broker-Dealer, the
          managing underwriters, if any, and each of their respective counsel, a
          reasonable opportunity to review copies of all such documents
          (including copies of any documents to be incorporated by reference
          therein and all exhibits thereto) proposed to be filed (in each case
          at least five Business Days prior to such filing). The Company and
          each Subsidiary Guarantor shall not file any such Registration
          Statement or Prospectus or any amendments or supplements thereto in
          respect of which the Holders must provide information for the
          inclusion therein without the Holders being afforded an opportunity to
          review such documentation if the Holders of a majority in aggregate
          principal amount of the Registrable Notes covered by such Registration
          Statement, or any such Participating Broker-Dealer, as the case may
          be, the managing underwriters, if any, or any of their respective
          counsel shall reasonably object in writing on a timely basis. A Holder
          shall be deemed to have reasonably objected to such filing if such
          Registration Statement, amendment, Prospectus or supplement, as
          applicable, as proposed to be filed, contains an untrue statement of a
          material fact or omits to state any material fact necessary to make
          the statements therein not


                                       12



          misleading or fails to comply with the applicable requirements of the
          Securities Act.

     (b)  Provide an indenture trustee for the Registrable Notes, the Exchange
          Notes or the Private Exchange Notes, as the case may be, and cause the
          Indenture (or other indenture relating to the Registrable Notes) to be
          qualified under the TIA not later than the effective date of the first
          Registration Statement; and in connection therewith, to effect such
          changes to such 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 such 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.

     (c)  Prepare and file with the SEC such pre-effective amendments and
          post-effective amendments to each Shelf Registration or Exchange
          Registration Statement, as the case may be, as may be necessary to
          keep such Registration Statement continuously effective for the
          Effectiveness Period or the Applicable Period, as the case may be;
          cause the related Prospectus to be supplemented by any Prospectus
          supplement required by applicable law, and as so supplemented to be
          filed pursuant to Rule 424 (or any similar provisions then in force)
          promulgated under the Securities Act; and comply with the provisions
          of the Securities Act and the Exchange Act applicable to them with
          respect to the disposition of all securities covered by such
          Registration Statement as so amended or in such Prospectus as so
          supplemented and with respect to the subsequent resale of any
          securities being sold by a Participating Broker-Dealer covered by any
          such Prospectus. The Company and each Subsidiary Guarantor shall not,
          during the Applicable Period, voluntarily take any action that would
          result in selling Holders of the Registrable Notes covered by a
          Registration Statement or Participating Broker-Dealers seeking to sell
          Exchange Notes not being able to sell such Registrable Notes or such
          Exchange Notes during that period, unless such action is required by
          applicable law, rule or regulation or permitted by this Agreement.

     (d)  Furnish to such selling Holders and Participating Broker-Dealers who
          so request in writing (i) upon the Company's receipt, a copy of the
          order of the SEC declaring such Registration Statement and any post
          effective amendment thereto effective, (ii) such reasonable number of
          copies of such Registration Statement and of each amendment and
          supplement thereto (in each case including any documents incorporated
          therein by reference and all exhibits), (iii) such reasonable number
          of copies of the Prospectus included in such Registration Statement
          (including each preliminary Prospectus) and each amendment and
          supplement thereto, and such reasonable number of copies of the final
          Prospectus as filed by the Company and each Subsidiary Guarantor
          pursuant to Rule 424(b) under the Securities Act, in conformity with
          the requirements of the Securities Act and each amendment and
          supplement thereto, and (iv) such other documents (including any
          amendments required to be filed pursuant to clause (c) of this
          Section), as any such Person may reasonably request in writing. The
          Company and the Subsidiary Guarantors hereby consent to the use of the
          Prospectus by each


                                       13



          of the selling Holders of Registrable Notes or each such Participating
          Broker-Dealer, as the case may be, and the underwriters or agents, if
          any, and dealers, if any, in connection with the offering and sale of
          the Registrable Notes covered by, or the sale by Participating
          Broker-Dealers of the Exchange Notes pursuant to, such Prospectus and
          any amendment or supplement thereto.

     (e)  If (1) a Shelf Registration is filed pursuant to Section 3, or (2) a
          Prospectus contained in an Exchange Registration Statement filed
          pursuant to Section 2 is required to be delivered under the Securities
          Act by any Participating Broker-Dealer who seeks to sell Exchange
          Notes during the Applicable Period relating thereto, the Company shall
          notify in writing the selling Holders of Registrable Notes, or each
          such Participating Broker-Dealer, as the case may be, the managing
          underwriters, if any, and each of their respective counsel promptly
          (but in any event within two Business Days) (i) when a Prospectus or
          any Prospectus supplement or post-effective amendment has been filed,
          and, with respect to a Registration Statement or any post-effective
          amendment, when the same has become effective (including in such
          notice a written statement that any Holder may, upon request, obtain,
          without charge, one conformed copy of such Registration Statement or
          post-effective amendment including financial statements and schedules,
          documents incorporated or deemed to be incorporated by reference and
          exhibits), (ii) of the issuance by the SEC of any stop order
          suspending the effectiveness of a Registration Statement or of any
          order preventing or suspending the use of any Prospectus or the
          initiation of any proceedings for that purpose, (iii) if at any time
          when a Prospectus is required by the Securities Act to be delivered in
          connection with sales of the Registrable Notes the representations and
          warranties of the Company and any Subsidiary Guarantor contained in
          any agreement (including any underwriting agreement) contemplated by
          Section 6(n) hereof cease to be true and correct, (iv) of the receipt
          by the Company or any Subsidiary Guarantor of any notification with
          respect to the suspension of the qualification or exemption from
          qualification of a Registration Statement or any of the Registrable
          Notes or the Exchange Notes to be sold by any Participating
          Broker-Dealer for offer or sale in any jurisdiction, or the initiation
          or threatening of any proceeding for such purpose, (v) of the
          happening of any event, the existence of any condition or any
          information becoming known that makes any statement made in such
          Registration Statement or related Prospectus or any document
          incorporated or deemed to be incorporated therein by reference untrue
          in any material respect or that requires the making of any changes in,
          or amendments or supplements to, such Registration Statement,
          Prospectus or documents so that, in the case of the Registration
          Statement and 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 light
          of the circumstances under which they were made, not misleading, (vi)
          of any reasonable determination by the Company or any Subsidiary
          Guarantor that a post-effective amendment to a Registration Statement
          would be appropriate and (vii) of any request by the SEC for
          amendments to the Registration Statement or supplements to the
          Prospectus or for additional information relating thereto.


                                       14



     (f)  Use its best efforts to prevent the issuance of any order suspending
          the effectiveness of a Registration Statement or of any order
          preventing or suspending the use of a Prospectus or suspending the
          qualification (or exemption from qualification) of any of the
          Registrable Notes or the Exchange Notes to be sold by any
          Participating Broker-Dealer, for sale in any jurisdiction, and, if any
          such order is issued, to use its best efforts to obtain the withdrawal
          of any such order at the earliest possible date.

     (g)  If (A) a Shelf Registration is filed pursuant to Section 3, (B) a
          Prospectus contained in an Exchange Registration Statement filed
          pursuant to Section 2 is required to be delivered under the Securities
          Act by any Participating Broker-Dealer who seeks to sell Exchange
          Notes during the Applicable Period or (C) reasonably requested in
          writing by the managing underwriters, if any, or the Holders of a
          majority in aggregate principal amount of the Registrable Notes being
          sold in connection with an underwritten offering, (i) promptly
          incorporate in a Prospectus supplement or post-effective amendment
          such information or revisions to information therein relating to such
          underwriters or selling Holders as the managing underwriters, if any,
          or such Holders or any of their respective counsel reasonably request
          in writing to be included or made 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 to be incorporated in such Prospectus supplements or
          post-effective amendment.

     (h)  Prior to any public offering of Registrable Notes or any delivery of a
          Prospectus contained in the Exchange Registration Statement by any
          Participating Broker-Dealer who seeks to sell Exchange Notes during
          the Applicable Period, use its best efforts to register or qualify,
          and to cooperate with the selling Holders of Registrable Notes or each
          such Participating Broker-Dealer, as the case may be, the
          underwriters, if any, and their respective counsel in connection with
          the registration or qualification (or exemption from such registration
          or qualification) of such Registrable Notes or Exchange Notes, as the
          case may be, for offer and sale under the securities or Blue Sky laws
          of such jurisdictions within the United States as any selling Holder,
          Participating Broker-Dealer or any managing underwriter or
          underwriters, if any, reasonably request in writing; provided that
          where Exchange Notes held by Participating Broker-Dealers or
          Registrable Notes are offered other than through an underwritten
          offering, the Company and each Subsidiary Guarantor agree to cause its
          counsel to perform Blue Sky investigations and file any registrations
          and qualifications required to be filed pursuant to this Section 6(h),
          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 reasonably
          necessary or advisable to enable the disposition in such jurisdictions
          of the Exchange Notes held by Participating Broker-Dealers or the
          Registrable Notes covered by the applicable Registration Statement;
          provided that neither the Company nor any Subsidiary Guarantor shall
          be required to (A) qualify generally to do business in any
          jurisdiction where it is not then so qualified, (B) take any


                                       15



          action that would subject it to general service of process in any such
          jurisdiction where it is not then so subject or (C) subject itself to
          taxation in any such jurisdiction where it is not then so subject.

          connection with such Registration Statement. Each Inspector shall
          agree in writing that it will keep the Records confidential and not
          disclose any of the Records unless (i) the disclosure of such Records

          Registration Statement, (ii) the release of such Records is ordered
          pursuant to a subpoena or other order from a court of competent

          involving or potentially involving such Inspector and arising out of,

          Broker-Dealer will be required to agree that information obtained by
          it as a result of such inspections shall be deemed confidential and
          shall not be used by it as the basis for any market transactions in

          required to further agree that it will, upon learning that disclosure
          of such Records is sought


                                       18



          in a court of competent jurisdiction, give notice to the Company and,
          to the extent practicable, use its best efforts to allow the Company,
          at its expense, to undertake appropriate action to prevent disclosure
          of the Records deemed confidential at its expense.

          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
          Notes are sold to underwriters in a 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 after the effective date of a Registration Statement,
          which statements shall cover said 12-month periods.

     (q)  Upon consummation of an Exchange Offer or Private Exchange, obtain an
          opinion of counsel to the Company and the Subsidiary Guarantors (in
          form, scope and substance reasonably satisfactory to the Initial
          Purchaser), addressed to the Trustee for the benefit of all Holders
          participating in the Exchange Offer or Private Exchange, as the case
          may be, to the effect that (i) the Company and the Subsidiary
          Guarantors have duly authorized, executed and delivered the Exchange
          Notes or the Private Exchange Notes, as the case may be, and the
          Indenture, (ii) the Exchange Notes or the Private Exchange Notes, as
          the case may be, and the Indenture constitute legal, valid and binding
          obligations of the Company and the Subsidiary Guarantors, enforceable
          against the Company and the Subsidiary Guarantors in accordance with
          their respective terms, except as such enforcement may be subject to
          customary United States and foreign exceptions and (iii) all
          obligations of the Company and the Subsidiary Guarantors under the
          Exchange Notes or the Private Exchange Notes, as the case may be, and

          obligations of the Company and the Subsidiary Guarantors under the
          Notes, Indenture and Collateral Agreements to the extent and as
          discussed in the Registration Statement.

     (r)  If the Exchange Offer or a Private Exchange is to be consummated, upon
          delivery of the Registrable Notes by the Holders to the Company and
          the Subsidiary Guarantors (or to such other Person as directed by the
          Company and the Subsidiary Guarantors) in exchange for the Exchange
          Notes or the Private Exchange Notes, as the case may be, the Company
          and the Subsidiary Guarantors shall mark, or caused to be marked, on
          such Registrable Notes that the Exchange Notes or the Private Exchange
          Notes, as the case may be, are being issued as substitute evidence of
          the indebtedness originally evidenced by the Registrable Notes;
          provided that in no event shall such Registrable Notes be marked as
          paid or otherwise satisfied.

          in connection with any filings required to be made with the NASD.

     (t)  Use its best efforts to cause all Securities covered by a Registration
          Statement to be listed on each securities exchange, if any, on which
          similar debt securities issued by the Company are then listed.

     (u)  Use its best efforts to take such other steps as may be reasonably
          necessary to effect the registration of the Registrable Notes covered
          by a Registration Statement contemplated hereby.

     (v)  The Company may require each seller of Registrable Notes or
          Participating Broker-Dealer as to which any registration is being

          seller or Participating Broker-Dealer and the distribution of such
          Registrable Notes as the Company may, from time to time, reasonably
          request in writing. The Company may exclude from such registration the
          Registrable Notes of any seller who fails to furnish such information
          within a reasonable time (which time in no event shall exceed 45 days,
          subject to Section 3(d) hereof) after receiving such request. Each
          seller of Registrable Notes or Participating Broker-Dealer as to which
          any registration is being effected agrees to furnish promptly to the
          Company all information required to be disclosed in order to make the
          information previously furnished by such seller not materially
          misleading.

     (w)  Each Holder of Registrable Notes and each Participating Broker-Dealer
          agrees by acquisition of such Registrable Notes or Exchange Notes to
          be sold by such Participating Broker-Dealer, as the case may be, that,
          upon receipt of any notice from the Company of the happening of any
          event of the kind described in Section 6(e)(2)(ii), 6(e)(2)(iii),
          6(e)(2)(iv), 6(e)(2)(v), or 6(e)(2)(vi), such Holder will forthwith
          discontinue disposition of such Registrable Notes covered by a
          Registration Statement and such Participating Broker-Dealer will
          forthwith discontinue disposition of such Exchange Notes pursuant to
          any Prospectus and, in each case, forthwith discontinue dissemination
          of such Prospectus until such Holder's or Participating
          Broker-Dealer's receipt of the copies of the supplemented or amended
          Prospectus contemplated by Section 6(k), or until it is advised in
          writing (the "Advice") by the Company and the Subsidiary Guarantors
          that the use of the applicable Prospectus may be resumed, and has
          received copies of any amendments or supplements thereto and, if so
          directed by the Company and the Subsidiary Guarantors, such Holder or
          Participating Broker-Dealer, as the case may be, will deliver to the
          Company all copies, other than permanent file copies, then in such
          Holder's or Participating Broker-Dealer's possession, of the
          Prospectus covering such Registrable Notes current at the time of the
          receipt of such notice. In the event the Company and the Subsidiary
          Guarantors shall give any such notice, the Applicable Period shall be
          extended by the number of days during such periods from and including
          the date of the giving of such notice to


                                       20



          and including the date when each Participating Broker-Dealer shall
          have received (x) the copies of the supplemented or amended Prospectus

          incurred, directly or indirectly caused by, related to, based upon,
          arising out of or in connection with any untrue or alleged untrue
          statement of a material fact contained in any Registration Statement,
          Prospectus or form of prospectus, or in any amendment or supplement
          thereto, or in any preliminary prospectus, or any omission or alleged
          omission to state therein 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, but only to
          the extent, that such Losses are finally judicially determined by a
          court of competent jurisdiction in a final, unappealable order, except
          insofar as such Losses are solely based upon information relating to
          such Holder or Participating Broker-Dealer and furnished in writing to
          the Company and the Subsidiary Guarantors (or reviewed and approved in
          writing) by such Holder or Participating Broker-Dealer or their
          counsel expressly for use therein; provided, however, that the Company
          and the Subsidiary Guarantors will not be liable to any Indemnified
          Party (as defined


                                       22



          below) under this Section 8 to the extent Losses were solely caused by
          an untrue statement or omission or alleged untrue statement or
          omission that was contained or made in any preliminary prospectus and
          corrected in the Prospectus or any amendment or supplement thereto if
          (i) the Prospectus does not contain any other untrue statement or
          omission or alleged untrue statement or omission of a material fact
          that was the subject matter of the related proceeding, (ii) any such
          Losses resulted from an action, claim or suit by any Person who
          purchased Registrable Notes or Exchange Notes which are the subject
          thereof from such Indemnified Party and (iii) it is established in the
          related proceeding that such Indemnified Party failed to deliver or
          provide a copy of the Prospectus (as amended or supplemented) to such
          Person with or prior to the confirmation of the sale of such
          Registrable Notes or Exchange Notes sold to such Person if required by
          applicable law, unless such failure to deliver or provide a copy of
          the Prospectus (as amended or supplemented) was a result of
          noncompliance by the Company with Section 6 of this Agreement. The
          Company and the Subsidiary Guarantors also agree to indemnify
          underwriters, selling brokers, dealer managers and similar securities
          industry professionals participating in the distribution, their
          officers, directors, agents and employees and each Person who controls
          such Persons (within the meaning of Section 5 of the Securities Act or
          Section 20(a) of the Exchange Act) to the same extent as provided
          above with respect to the indemnification of the Holders or the
          Participating Broker-Dealer.

     (b)  Indemnification by Holder. In connection with any Registration
          Statement, Prospectus or form of prospectus, any amendment or
          supplement thereto, or any preliminary prospectus in which a Holder is
          participating, such Holder shall furnish to the Company and the
          Subsidiary Guarantors in writing such information as the Company and
          the Subsidiary Guarantors reasonably request for use in connection
          with any Registration Statement, Prospectus or form of prospectus, any
          amendment or supplement thereto, or any preliminary prospectus and
          shall indemnify and hold harmless the Company, the Subsidiary
          Guarantors, their respective directors and each Person, if any, who
          controls the Company and the Subsidiary Guarantors (within the meaning
          of Section 15 of the Securities Act and Section 20(a) of the Exchange
          Act), and the directors, officers and partners of such controlling
          persons, to the fullest extent lawful, from and against all Losses
          arising out of or based upon any untrue or alleged untrue statement of
          a material fact contained in any Registration Statement, Prospectus or
          form of prospectus or in any amendment or supplement thereto or in any
          preliminary prospectus, or 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 light of the circumstances under
          which they were made, not misleading to the extent, but only to the
          extent, that such losses are finally judicially determined by a court
          of competent jurisdiction in a final, unappealable order to have
          resulted solely from an untrue statement or alleged untrue statement
          of a material fact or omission or alleged omission of a material fact
          contained in or omitted from any information so furnished in writing
          by such Holder to the Company and the Subsidiary Guarantors expressly
          for use therein. Notwithstanding the foregoing, in no event


                                       23



          shall the liability of any selling Holder be greater in amount than
          such Holder's Maximum Contribution Amount (as defined below).

     (c)  Conduct of Indemnification Proceedings. If any proceeding shall be
          brought or asserted against any Person entitled to indemnity hereunder
          (an "Indemnified Party"), such Indemnified Party shall promptly notify
          the party or parties from which such indemnity is sought (the
          "Indemnifying Party" or "Indemnifying Parties", as applicable) in
          writing; provided, that the failure to so notify the Indemnifying
          Parties shall not relieve the Indemnifying Parties from any obligation
          or liability except to the extent (but only to the extent) that it
          shall be finally determined by a court of competent jurisdiction
          (which determination is not subject to appeal) that the Indemnifying
          Parties have been prejudiced materially by such failure.

     The Indemnifying Party shall have the right, exercisable by giving written
notice to an Indemnified Party, within 20 Business Days after receipt of written
notice from such Indemnified Party of such proceeding, to assume, at its
expense, the defense of any such proceeding, provided, that an Indemnified Party
shall have the right to employ separate counsel in any such proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party or parties unless: (1) the
Indemnifying Party has agreed to pay such fees and expenses; or (2) the
Indemnifying Party shall have failed promptly to assume the defense of such
proceeding or shall have failed to employ counsel reasonably satisfactory to
such Indemnified Party; or (3) the named parties to any such proceeding
(including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party or any of its affiliates or controlling persons, and such
Indemnified Party shall have been advised by counsel that there may be one or
more defenses available to such Indemnified Party that are in addition to, or in
conflict with, those defenses available to the Indemnifying Party or such
affiliate or controlling person (in which case, if such Indemnified Party
notifies the Indemnifying Parties in writing that it elects to employ separate
counsel at the expense of the Indemnifying Parties, the Indemnifying Parties
shall not have the right to assume the defense and the reasonable fees and
expenses of such counsel shall be at the expense of the Indemnifying Party; it
being understood, however, that, the Indemnifying Party shall not, in connection
with any one such proceeding or separate but substantially similar or related
proceedings 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 (together with appropriate local counsel) at any
time for such Indemnified Party).

     No Indemnifying Party shall be liable for any settlement of any such
proceeding effected without its written consent, which shall not be unreasonably
withheld, but if settled with its written consent, or if there be a final
judgment for the plaintiff in any such proceeding, each Indemnifying Party
jointly and severally agrees, subject to the exceptions and limitations set
forth above, to indemnify and hold harmless each Indemnified Party from and
against any and all Losses by reason of such settlement or judgment. The
Indemnifying Party shall not consent to the entry of any judgment or enter into
any settlement that does not include as an unconditional term thereof the giving
by the claimant or plaintiff to each Indemnified Party of a release, in form and
substance reasonably satisfactory to the Indemnified Party, from all liability
in respect


                                       24



of such proceeding for which such Indemnified Party would be entitled to
indemnification hereunder (whether or not any Indemnified Party is a party
thereto).

     (d)  Contribution. If the indemnification provided for in this Section 8 is
          unavailable to an Indemnified Party or is insufficient to hold such
          Indemnified Party harmless for any Losses in respect of which this
          Section 8 would otherwise apply by its terms (other than by reason of
          exceptions provided in this Section 8), then each applicable
          Indemnifying Party, in lieu of indemnifying such Indemnified Party,
          shall have a joint and several obligation to contribute to the amount
          paid or payable by such Indemnified Party as a result of such Losses,
          in such proportion as is appropriate to reflect the relative fault of
          the Indemnifying Party, on the one hand, and such Indemnified Party,
          on the other hand, in connection with the actions, statements or
          omissions that resulted in such Losses as well as any other relevant
          equitable considerations. The relative fault of such Indemnifying
          Party, on the one hand, and Indemnified Party, on the other hand,
          shall be determined by reference to, among other things, whether any
          untrue or alleged untrue statement of a material fact or omission or
          alleged omission to state a material fact relates to information
          supplied by such Indemnifying Party or Indemnified Party, and the
          parties' relative intent, knowledge, access to information and
          opportunity to correct or prevent any such statement or omission. The
          amount paid or payable by an Indemnified Party as a result of any
          Losses shall be deemed to include any legal or other fees or expenses
          incurred by such party in connection with any proceeding, to the
          extent such party would have been indemnified for such fees or
          expenses if the indemnification provided for in Section 8(a) or 8(b)
          was available to such party.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 8(d), a selling Holder shall not
be required to contribute, in the aggregate, any amount in excess of such
Holder's Maximum Contribution Amount. A selling Holder's "Maximum Contribution
Amount" shall equal the excess of (i) the aggregate proceeds received by such
Holder pursuant to the sale of such Registrable Notes or Exchange Notes over
(ii) the aggregate amount of damages that such Holder 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 Holders' obligations to contribute pursuant to this
Section 8(d) are several in proportion to the respective principal amount of the
Registrable Securities held by each Holder hereunder and not joint. The
Company's and Subsidiary Guarantors' obligations to contribute pursuant to this
Section 8(d) are joint and several.

     The indemnity and contribution agreements contained in this Section 8 are
in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.


                                       25



9. RULES 144 AND 144A

     The Company covenants that it shall (a) file the reports required to be
filed by it (if so required) under the Securities Act and the Exchange Act in a
timely manner and, if at any time the Company is not required to file such
reports, it will, upon the written request of any Holder of Registrable Notes,
make publicly available other information necessary to permit sales pursuant to
Rule 144 and 144A and (b) take such further action as any Holder may reasonably
request in writing, all to the extent required from time to time to enable such
Holder to sell Registrable Notes without registration under the Securities Act
pursuant to the exemptions provided by Rule 144 and Rule 144A. Upon the request
of any Holder, the Company shall deliver to such Holder a written statement as
to whether it has complied with such information and requirements.

10. UNDERWRITTEN REGISTRATIONS OF REGISTRABLE NOTES

     If any of the Registrable Notes covered by any Shelf Registration is to be
sold in an underwritten offering, the investment banker or investment bankers
and manager or managers that will manage the offering will be selected by the
Holders of a majority in aggregate principal amount of such Registrable Notes
included in such offering; provided, however, that such investment banker or
investment bankers and manager or managers must be reasonably acceptable to the
Company.

     No Holder of Registrable Notes may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

11. MISCELLANEOUS

     (a)  Remedies. In the event of a breach by either the Company or any of the
          Subsidiary Guarantors of any of their respective obligations under
          this Agreement, each Holder, in addition to being entitled to exercise
          all rights provided herein, in the Indenture or, in the case of the
          Initial Purchaser, in the Purchase Agreement, or granted by law,
          including recovery of damages, will be entitled to specific
          performance of its rights under this Agreement. The Company and the
          Subsidiary Guarantors agree that monetary damages would not be
          adequate compensation for any loss incurred by reason of a breach by
          either the Company or any of the Subsidiary Guarantors 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, the Company shall (and shall cause each Subsidiary Guarantor
          to) waive the defense that a remedy at law would be adequate.

     (b)  No Inconsistent Agreements. The Company and each of the Subsidiary
          Guarantors have not entered, as of the date hereof, and the Company
          and each of


                                       26



          the Subsidiary Guarantors shall not enter, after the date of this
          Agreement, into any agreement with respect to any of its securities
          that is inconsistent with the rights granted to the Holders of
          Securities in this Agreement or otherwise conflicts with the
          provisions hereof. The Company and each of the Subsidiary Guarantors
          have not entered and will not enter into any agreement with respect to
          any of its securities that will grant to any Person piggy-back rights
          with respect to a Registration Statement.

     (c)  Adjustments Affecting Registrable Notes. The Company shall not,
          directly or indirectly, take any action with respect to the
          Registrable Notes as a class that would adversely affect the ability
          of the Holders to include such Registrable Notes in a registration
          undertaken pursuant to this Agreement.

     (d)  Amendments and Waivers. The provisions of this Agreement may not be
          amended, modified or supplemented, and waivers or consents to
          departures from the provisions hereof may not be given, otherwise than
          with the prior written consent of the Holders of not less than a
          majority in aggregate principal amount of the then outstanding
          Registrable Notes in circumstances that would adversely affect any
          Holders of Registrable Notes; provided, however, that Section 8 and
          this Section 11(d) may not be amended, modified or supplemented
          without the prior written consent of each Holder. 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 Notes whose securities are being tendered
          pursuant to the Exchange Offer or sold pursuant to a Notes
          Registration Statement and that does not directly or indirectly
          affect, impair, limit or compromise the rights of other Holders of
          Registrable Notes may be given by Holders of at least a majority in
          aggregate principal amount of the Registrable Notes being tendered or
          being sold by such Holders pursuant to such Notes Registration
          Statement.

     (i)  Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
          ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
          PRINCIPLES OF CONFLICT OF LAW. THE COMPANY HEREBY IRREVOCABLY SUBMITS
          TO THE JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH
          OF MANHATTAN IN THE CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN
          THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK IN RESPECT OF ANY
          SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
          AGREEMENT, AND IRREVOCABLY ACCEPTS FOR ITS AND IN RESPECT OF ITS
          PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF THE AFORESAID
          COURTS. THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY
          EFFECTIVELY DO SO UNDER APPLICABLE LAW, TRIAL BY JURY AND ANY
          OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF
          ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY
          CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH
          COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THE COMPANY
          IRREVOCABLY CONSENTS, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO
          UNDER APPLICABLE LAW, TO THE SERVICE OF PROCESS OF ANY OF THE
          AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING
          OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO
          THE COMPANY AT ITS SAID ADDRESS, SUCH SERVICE TO BECOME EFFECTIVE 30
          DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY
          HOLDER TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO
          COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE COMPANY IN
          ANY OTHER JURISDICTION.

     (j)  Severability. 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.

     (k)  Securities Held by the Company or Its Affiliates. Whenever the consent
          or approval of Holders of a specified percentage of Securities is
          required hereunder, Securities held by the Company or its affiliates
          (as such term is defined in Rule


                                       29



          405 under the Securities Act) shall not be counted in determining
          whether such consent or approval was given by the Holders of such
          required percentage.

     (l)  Third Party Beneficiaries. Holders and Participating Broker-Dealers
          are intended third party beneficiaries of this Agreement and this
          Agreement may be enforced by such Persons.

     (m)  Entire Agreement. This Agreement, together with the Purchase
          Agreement, the Indenture and the Collateral Agreements, is intended by
          the parties as a final and exclusive statement of the agreement and
          understanding of the parties hereto in respect of the subject matter
          contained herein and therein and any and all prior oral or written
          agreements, representations, or warranties, contracts, understanding,
          correspondence, conversations and memoranda between the Initial
          Purchaser on the one hand and the Company and the Subsidiary
          Guarantors on the other, or between or among any agents,

          interest or successors in interest with respect to the subject matter
          hereof and thereof are merged herein and replaced hereby.

     (n)  Blackout Period.

          (i)  Notwithstanding anything herein to the contrary, the Company may
               suspend the filing, effectiveness or use of any Registration
               Statement (and therefore suspend sales thereunder) for certain
               periods ("Blackout Periods") if the majority of the Company's
               board of directors (the "Board") determines in good faith that
               the offer or sale of Registrable Securities thereunder would (A)
               materially impede, delay or interfere with any material pending
               or proposed financing, acquisition, corporate reorganization or
               other similar transaction involving the Company for which the
               Board has authorized negotiations; or (B) require disclosure of
               material nonpublic information which, if disclosed at such time,
               would be materially harmful to the Company's interests.

          (ii) The cumulative Blackout Periods in any 12-month period commencing
               on the Closing Date may not exceed an aggregate of 90 days during
               any 12-month period. The Company may exercise its rights pursuant
               to this Section 11(n) twice during any 12-month period, and then
               only as to separate events.


                                       30



     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.
