      2. Registration Under the Securities Act.

            (a) Except as set forth in Section 2(b) below, the Company agrees to
      file under the Securities Act, as soon as practicable, but no later than
      90 days after the Closing Date, a registration statement relating to an
      offer to exchange (such registration statement, the "Exchange Registration
      Statement", and such offer, the "Exchange Offer") any and all of the
      Securities for a like aggregate principal amount of debt securities issued
      by the Company and guaranteed by each of the Guarantors, which debt
      securities and guarantees are substantially identical to the Securities
      and the Guarantees, respectively (and are entitled to the benefits of a
      trust indenture which is substantially identical to the Indenture or is
      the Indenture and which has been qualified under the Trust Indenture Act),
      except that they have been registered pursuant to an effective
      registration statement under the Securities Act and do not contain
      provisions for the additional interest contemplated in Section 2(c) below
      (such new debt securities hereinafter called "Exchange Securities"). The
      Company agrees to use its reasonable best efforts to cause the Exchange
      Registration Statement to become effective under the Securities Act as
      soon as practicable, but no later than 180 days after the Closing Date.
      The Exchange Offer will be registered under the Securities Act on the
      appropriate form and will comply with all applicable tender offer rules
      and regulations under the Exchange Act. The Company further agrees to use
      its reasonable best efforts to commence and complete the Exchange Offer
      promptly, but no later than 30 business days after such registration
      statement has become effective, hold the Exchange Offer open for at least
      20 business days and exchange Exchange Securities for all Registrable
      Securities that have been properly tendered and not withdrawn on or prior
      to the expiration of the Exchange Offer. The Exchange Offer will be deemed
      to have been "completed" only if the debt securities received by holders
      other than Restricted Holders in the Exchange Offer for Registrable
      Securities are, upon receipt, transferable by each such holder without
      need for further compliance with Section 5 of the Securities Act (except
      for the requirement to deliver a prospectus included in the Exchange
      Registration Statement applicable to resales by broker-dealers of Exchange
      Securities received by such broker-dealer pursuant to an Exchange Offer in
      exchange for Registrable Securities other than those acquired by the
      broker-dealer directly from the Company) and without material restrictions
      under the blue sky or securities laws of a substantial majority of the
      States of the United States of America. The Exchange Offer shall be deemed
      to have been completed upon the earlier to occur of (i) the Company having
      exchanged the Exchange Securities for all outstanding Registrable
      Securities pursuant to the Exchange Offer and (ii) the Company having
      exchanged, pursuant to the Exchange Offer, Exchange Securities for all
      Registrable Securities that have been properly tendered and not withdrawn
      before the expiration of the Exchange Offer, which shall be on a date that
      is at least 30 days following the commencement of the


                                       4


      Exchange Offer. The Company agrees (x) to include in the Exchange
      Registration Statement a prospectus for use in any resales by any holder
      of Exchange Securities that is a broker-dealer (where such Exchange
      Security was received by a broker-dealer in an Exchange Offer in exchange
      for a Registrable Security that was acquired by such broker-dealer for its
      own account as a result of market-making or other trading activities, so
      long as such Registrable Security was not acquired directly from the
      Company or an affiliate of the Company) and (y) to keep such Exchange
      Registration Statement effective for a period (the "Resale Period")
      beginning when Exchange Securities are first issued in the Exchange Offer
      and ending upon the earlier of the expiration of the 120th day after the
      Exchange Offer has been completed or such time as such broker-dealers no
      longer own any Registrable Securities. With respect to such Exchange
      Registration Statement, such holders shall have the benefit of the rights
      of indemnification and contribution set forth in Sections 6(a), (c), (d)
      and (e) hereof.

            (b) If (i) on or prior to the time the Exchange Offer is completed
      existing Commission interpretations are changed such that the debt
      securities or the related guarantees received by holders other than
      Restricted Holders in the Exchange Offer for Registrable Securities are
      not or would not be, upon receipt, transferable by each such holder
      without need for further compliance with Section 5 of the Securities Act
      (except for the requirement to deliver a prospectus included in the
      Exchange Registration Statement applicable to resales by broker-dealers of
      Exchange Securities received by such broker-dealer pursuant to an Exchange
      Offer in exchange for Registrable Securities that were acquired by such
      broker-dealer for its own account as a result of market-making or other
      trading activities, so long as such Registrable Security was not acquired
      directly from the Company or an affiliate of the Company), (ii) the
      Exchange Offer has not been completed within 225 days following the
      Closing Date or (iii) the Exchange Offer is not available to any holder of
      the Securities and such holder notifies the Company in writing prior to
      the 255th day following the Closing Date that: (A) it is prohibited by law
      or Commission policy from participating in the Exchange Offer; or (B) that
      it may not resell the Exchange Securities acquired by it in the Exchange
      Offer to the public without delivering a prospectus and the prospectus
      contained in the Exchange Registration Statement is not appropriate or
      available for such resales; or (C) that it is a broker-dealer and owns
      Registrable Securities acquired directly from the Company or an affiliate
      of the Company (an "Electing Holder"), the Company shall, in lieu of (or,
      in the case of clause (iii), in addition to) conducting the Exchange Offer
      contemplated by Section 2(a), file under the Securities Act as soon as
      practicable, but no later than the later of 60 days after the time such
      obligation to file arises or such later date on which the Exchange
      Registration Statement would have been required to be filed, a "shelf"
      registration statement providing for the registration of, and the sale on
      a continuous or delayed basis by the holders of, all of the Registrable
      Securities, pursuant to Rule 415 or any similar rule that may be adopted
      by the Commission (such filing, the "Shelf Registration" and such
      registration statement, the "Shelf Registration Statement"). The Company
      agrees to use its reasonable best efforts (x) to cause the Shelf
      Registration Statement to become or be declared effective no later than
      120 days after such Shelf Registration Statement is filed or such later
      date on which the Exchange Registration Statement would have been required
      to be declared effective and to keep such Shelf Registration Statement
      continuously effective for a period ending on the earlier of the second
      anniversary of the Effective Time or such time as there are no longer any
      Registrable Securities outstanding, provided, however, that no holder
      shall be entitled to be named as a selling securityholder in the Shelf
      Registration Statement or to use the prospectus forming a part thereof for
      resales of Registrable Securities unless such holder is an Electing Holder
      who agrees to be bound by all of the provisions of this Agreement
      applicable to such holder, and (y) after the Effective Time of


                                       5


      the Shelf Registration Statement, promptly upon the request of any holder
      of Registrable Securities that is not then an Electing Holder, to take any
      action reasonably necessary to enable such holder to use the prospectus
      forming a part thereof for resales of Registrable Securities, including,
      without limitation, any action reasonably necessary to identify such
      holder as a selling securityholder in the Shelf Registration Statement,
      provided, however, that nothing in this Clause (y) shall relieve any such
      holder of the obligation to return a completed and signed Notice and
      Questionnaire to the Company in accordance with Section 3(d)(iii) hereof.
      The Company further agrees to supplement or make amendments to the Shelf
      Registration Statement, as and when required by the rules, regulations or
      instructions applicable to the registration form used by the Company for
      such Shelf Registration Statement or by the Securities Act or rules and
      regulations thereunder for shelf registration, and the Company agrees to
      furnish to each Electing Holder copies of any such supplement or amendment
      prior to its being used or promptly following its filing with the
      Commission.

            (c) In the event that (i) the Company has not filed the Exchange
      Registration Statement or Shelf Registration Statement on or before the
      date on which such registration statement is required to be filed pursuant
      to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration
      Statement or Shelf Registration Statement has not become effective or been
      declared effective by the Commission on or before the date on which such
      registration statement is required to become or be declared effective
      pursuant to Section 2(a) or 2(b), respectively, or (iii) the Exchange
      Offer has not been completed within 30 business days after the initial
      effective date of the Exchange Registration Statement relating to the
      Exchange Offer (if the Exchange Offer is then required to be made) or (iv)
      any Exchange Registration Statement or Shelf Registration Statement
      required by Section 2(a) or 2(b) hereof is filed and declared effective
      but shall thereafter, prior to the time such Exchange Registration
      Statement or Shelf Registration Statement is no longer required to be
      effective pursuant to Section 2(a) or 2(b), either be withdrawn by the
      Company or shall become subject to an effective stop order issued pursuant
      to Section 8(d) of the Securities Act suspending the effectiveness of such
      registration statement (except as specifically permitted herein) without
      being succeeded immediately by an additional registration statement filed
      and declared effective (each such event referred to in clauses (i) through
      (iv), a "Registration Default" and each period during which a Registration
      Default has occurred and is continuing, a "Registration Default Period"),
      then, as liquidated damages for such Registration Default, subject to the
      provisions of Section 9(b), special interest ("Special Interest"), in
      addition to the Base Interest, shall accrue at a per annum rate of 0.25%
      for the first 90 days of the Registration Default Period. The amount of
      Special Interest shall increase by an additional 0.25% per annum of the
      principal amount of the Securities with respect to each subsequent 90-day
      period until all Registration Defaults have been cured, up to a maximum
      amount of 1.0% per annum of the principal amount of the Securities.

            (d) The Company shall take, and shall cause the Guarantors to take,
      all actions reasonably necessary or advisable to be taken by it to ensure
      that the transactions contemplated herein are effected as so contemplated,
      including all actions reasonably necessary or desirable to register the
      Guarantees under the registration statement contemplated in Section 2(a)
      or 2(b) hereof, as applicable.

            (e) Any reference herein to a registration statement as of any time
      shall be deemed to include any document incorporated, or deemed to be
      incorporated, therein by reference as of such time and any reference
      herein to any post-effective amendment to a registration


                                       6


      statement as of any time shall be deemed to include any document
      incorporated, or deemed to be incorporated, therein by reference as of
      such time.

      3. Registration Procedures.

            If the Company files a registration statement pursuant to Section
2(a) or Section 2(b), the following provisions shall apply:

            (a) At or before the Effective Time of the Exchange Offer or the
      Shelf Registration, as the case may be, the Company shall qualify the
      Indenture under the Trust Indenture Act of 1939, as amended (the "Trust
      Indenture Act").

            (b) In the event that such qualification would require the
      appointment of a new trustee under the Indenture, the Company shall
      appoint a new trustee thereunder pursuant to the applicable provisions of
      the Indenture.

            (c) In connection with the Company's obligations with respect to the
      registration of Exchange Securities as contemplated by Section 2(a) (the
      "Exchange Registration"), if applicable, the Company shall, as soon as
      practicable (or as otherwise specified):

                  (i) prepare and file with the Commission, as soon as
            practicable but no later than 90 days after the Closing Date, an
            Exchange Registration Statement on any form which may be utilized by
            the Company and which shall permit the Exchange Offer and resales of
            Exchange Securities by broker-dealers during the Resale Period to be
            effected as contemplated by Section 2(a), and use its reasonable
            best efforts to cause such Exchange Registration Statement to become
            effective as soon as practicable thereafter, but no later than 180
            days after the Closing Date;

                  (ii) as soon as practicable prepare and file with the

            contemplated in Section 2(a) hereof and as may be required by the
            applicable rules and regulations of the Commission and the
            instructions applicable to the form of such Exchange Registration
            Statement, and promptly provide each broker-dealer holding Exchange

            all material respects with the requirements of the Securities Act
            and the Trust Indenture Act and the rules and regulations of the
            Commission thereunder, as such broker-dealer reasonably may request,
            in a timely manner, prior to the expiration of the Resale Period,
            for use in connection with resales of Exchange Securities;

                  (iii) promptly notify each broker-dealer that has requested or
            received copies of the prospectus included in such registration
            statement, and confirm such advice in writing, (A) when such
            Exchange Registration Statement or the prospectus included therein
            or any prospectus amendment or supplement or post-effective
            amendment has been filed with the Commission, and, with respect to
            such Exchange Registration Statement or any post-effective

            receipt by the Company of any notification with respect to the
            suspension of the qualification of the Exchange Securities for sale

            effected pursuant thereto, each of which notices shall contain the
            text of the amendment or waiver proposed or effected, as the case
            may be;

                  (xix) in the event that any broker-dealer registered under the
            Exchange Act shall underwrite any Registrable Securities or
            participate as a member of an underwriting syndicate or selling
            group or "assist in the distribution" (within the meaning of the
            Conduct Rules (the "Conduct Rules") of the National Association of
            Securities Dealers, Inc. ("NASD") or any successor thereto, as
            amended from time to time)


                                       14


            thereof, whether as a holder of such Registrable Securities or as an
            underwriter, a placement or sales agent or a broker or dealer in
            respect thereof, or otherwise, assist such broker-dealer in
            complying with the requirements of such Conduct Rules, including by
            (A) if such Conduct Rules shall so require, engaging a "qualified
            independent underwriter" (as defined in such Conduct Rules) to
            participate in the preparation of the Shelf Registration Statement
            relating to such Registrable Securities, to exercise usual standards
            of due diligence in respect thereto and, if any portion of the
            offering contemplated by such Shelf Registration Statement is an
            underwritten offering or is made through a placement or sales agent,
            to recommend the yield of such Registrable Securities, (B)
            indemnifying any such qualified independent underwriter to the
            extent of the indemnification of underwriters provided in Section 6
            hereof, and (C) providing such information to such broker-dealer as
            may be required in order for such broker-dealer to comply with the
            requirements of the Conduct Rules; and

                  (xx) comply with all applicable rules and regulations of the
            Commission, and make generally available to its securityholders as
            soon as practicable but in any event not later than eighteen months
            after the effective date of such Shelf Registration Statement, an
            earning statement of the Company and its subsidiaries complying with
            Section 11(a) of the Securities Act (including, at the option of the
            Company, Rule 158 thereunder).

            (e) In the event that the Company would be required, pursuant to
      Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement
      or sales agent, if any, therefor and the managing underwriters, if any,
      thereof, the Company shall without delay prepare and furnish to each of
      the Electing Holders, to each placement or sales agent, if any, and to
      each such underwriter, if any, a reasonable number of copies of a
      prospectus supplemented or amended so that, as thereafter delivered to
      purchasers of Registrable Securities, such prospectus shall conform in all
      material respects to the applicable requirements of the Securities Act and
      the Trust Indenture Act and the rules and regulations of the Commission
      thereunder and shall not contain an untrue statement of a material fact or
      omit to state a material fact required to be stated therein or necessary
      to make the statements therein not misleading in light of the
      circumstances then existing. Each Electing Holder agrees that upon receipt
      of any notice from the Company pursuant to Section 3(d)(viii)(F) hereof,
      such Electing Holder shall forthwith discontinue the disposition of
      Registrable Securities pursuant to the Shelf Registration Statement
      applicable to such Registrable Securities until such Electing Holder shall
      have received copies of such amended or supplemented prospectus, and if so
      directed by the Company, such Electing Holder shall deliver to the Company
      (at the Company's expense) all copies, other than permanent file copies,
      then in such Electing Holder's possession of the prospectus covering such
      Registrable Securities at the time of receipt of such notice.

            (f) In the event of a Shelf Registration, in addition to the
      information required to be provided by each Electing Holder in its Notice
      Questionnaire, the Company may require such Electing Holder to furnish to
      the Company such additional information regarding such Electing Holder and
      such Electing Holder's intended method of distribution of Registrable
      Securities as may be required in order to comply with the Securities Act.
      Each such Electing Holder agrees to notify the Company as promptly as
      practicable of any inaccuracy or change in information previously
      furnished by such Electing Holder to the Company or of the occurrence of
      any event in either case as a result of which any prospectus relating to
      such Shelf Registration contains or would contain an untrue statement of a
      material fact


                                       15


      regarding such Electing Holder or such Electing Holder's intended method
      of disposition of such Registrable Securities or omits to state any
      material fact regarding such Electing Holder or such Electing Holder's
      intended method of disposition of such Registrable Securities required to
      be stated therein or necessary to make the statements therein not
      misleading in light of the circumstances then existing, and promptly to
      furnish to the Company any additional information required to correct and
      update any previously furnished information or required so that such
      prospectus shall not contain, with respect to such Electing Holder or the
      disposition of such Registrable Securities, 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 not misleading in
      light of the circumstances then existing.

            (g) Until the expiration of two years after the Closing Date, the
      Company will not, and will not permit any of its "affiliates" (as defined
      in Rule 144) to, resell any of the Securities that have been reacquired by
      any of them except pursuant to an effective registration statement under
      the Securities Act.

      that can be expected to cause a material adverse change, in or affecting
      the general affairs, management, financial position, stockholders' equity
      or results of operations of the Company and the Guarantors taken as a

      6. Indemnification.

            (a) Indemnification by the Company and each of the Guarantors. The
      Company and each of the Guarantors, jointly and severally, will indemnify
      and hold harmless each of the holders of Registrable Securities included
      in an Exchange Registration Statement, each of the Electing Holders of
      Registrable Securities included in a Shelf Registration Statement and each
      person who controls such holder within the meaning of the Securities Act
      or Exchange Act against any losses, claims, damages or liabilities, joint
      or several, to which such indemnified person may become subject under the
      Securities Act or otherwise, insofar as such losses, claims, damages or
      liabilities (or actions in respect thereof) arise out of or are based upon
      an untrue statement or alleged untrue statement of a material fact
      contained in any Exchange Registration Statement or Shelf Registration
      Statement, as the case may be, under which such Registrable Securities
      were registered under the Securities Act, or any preliminary, final or
      summary prospectus contained therein or furnished by the Company to any
      such indemnified person, or any amendment or supplement thereto, or arise
      out of or are based upon the omission or alleged omission to state therein
      a material fact required to be stated therein or necessary to make the
      statements therein not misleading, and will reimburse such indemnified
      person for any legal or other expenses reasonably incurred by them in
      connection with investigating or defending any such action or claim as
      such expenses are incurred; provided, however, that none of the Company or
      the Guarantors shall be liable to any such person in any such case to the
      extent that any such loss, claim, damage or liability arises out of or is
      based upon an untrue statement or alleged untrue statement or omission or
      alleged omission made in such registration


                                       18


      statement, or preliminary, final or summary prospectus, or amendment or
      supplement thereto, in reliance upon and in conformity with written
      information furnished to the Company by such person expressly for use
      therein. The Company will also indemnify agents and underwriters to the
      same extent as provided above with respect to the indemnification of
      Electing Holders of the Registrable Securities.

            (b) Indemnification by the Holders and any Agents and Underwriters.
      The Company may require, as a condition to including any Registrable
      Securities in any registration statement filed pursuant to Section 2(b)
      hereof and to entering into any underwriting agreement with respect
      thereto, that the Company shall have received an undertaking reasonably
      satisfactory to it from the Electing Holder of such Registrable Securities
      and from each underwriter named in any such underwriting agreement,
      severally and not jointly, to (i) indemnify and hold harmless the Company,
      each of the Guarantors, each person who controls the Company or any of the
      Guarantors within the meaning of the Securities Act or Exchange Act and
      all other holders of Registrable Securities, against any losses, claims,
      damages or liabilities to which such indemnified person may become
      subject, under the Securities Act or otherwise, insofar as such losses,
      claims, damages or liabilities (or actions in respect thereof) arise out
      of or are based upon an untrue statement or alleged untrue statement of a
      material fact contained in such registration statement, or any
      preliminary, final or summary prospectus contained therein or furnished by
      the Company to any such indemnified person, or any amendment or supplement
      thereto, or arise out of or are based upon the omission or alleged
      omission to state therein a material fact required to be stated therein or
      necessary to make the statements therein not misleading, in each case to
      the extent, but only to the extent, that such untrue statement or alleged
      untrue statement or omission or alleged omission was made in reliance upon
      and in conformity with written information furnished to the Company by
      such indemnified person expressly for use therein, and (ii) reimburse the
      Company and each of the Guarantors for any legal or other expenses
      reasonably incurred by the Company and each of the Guarantors in
      connection with investigating or defending any such action or claim as
      such expenses are incurred; provided, however, that no such Electing
      Holder shall be required to undertake liability to any person under this
      Section 6(b) for any amounts in excess of the dollar amount of the
      proceeds to be received by such Electing Holder from the sale of such
      Electing Holder's Registrable Securities pursuant to such registration.

            (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
      party under subsection (a) or (b) above of written notice of the
      commencement of any action or proceeding (including a government
      investigation), such indemnified party shall, if a claim in respect
      thereof is to be made against an indemnifying party pursuant to the
      indemnification provisions of or contemplated by this Section 6, notify
      such indemnifying party in writing of the commencement thereof; but the
      omission so to notify the indemnifying party shall not relieve it from any
      liability which it may have to any indemnified party otherwise than under
      the indemnification provisions of or contemplated by Section 6(a) or 6(b)
      hereof. In case any such action shall be brought against any indemnified
      party and it shall notify an indemnifying party of the commencement
      thereof, such indemnifying party shall be entitled to participate therein
      and, to the extent that it shall wish, jointly with any other indemnifying
      party similarly notified, to assume the defense thereof, with counsel
      reasonably satisfactory to such indemnified party (who shall not, except
      with the consent of the indemnified party, be counsel to the indemnifying
      party), and, after notice from the indemnifying party to such indemnified
      party of its election so to assume the defense thereof, such indemnifying
      party shall not be liable to such indemnified party for any legal expenses
      of other counsel or any other expenses, in each case subsequently incurred
      by such indemnified party, in


                                       19


      connection with the defense thereof other than reasonable costs of
      investigation. No indemnifying party shall, without the prior written
      consent of the indemnified party, effect the settlement or compromise of,
      or consent to the entry of any judgment with respect to, any pending or
      threatened action or claim in respect of which indemnification or
      contribution may be sought hereunder (whether or not the indemnified party
      is an actual or potential party to such action or claim) unless such
      settlement, compromise or judgment (i) includes an unconditional release
      of the indemnified party from all liability arising out of such action or
      claim and (ii) does not include a statement as to or an admission of
      fault, culpability or a failure to act by or on behalf of any indemnified
      party.

            (d) Contribution. If for any reason the indemnification provisions
      contemplated by Section 6(a) or Section 6(b) are unavailable to or
      insufficient to hold harmless an indemnified party in respect of any
      losses, claims, damages or liabilities (or actions in respect thereof)
      referred to therein, then each indemnifying party shall contribute to the
      amount paid or payable by such indemnified party as a result of such
      losses, claims, damages or liabilities (or actions in respect thereof) in
      such proportion as is appropriate to reflect the relative fault of the
      indemnifying party and the indemnified party in connection with the
      statements or omissions which resulted in such losses, claims, damages or
      liabilities (or actions in respect thereof), as well as any other relevant
      equitable considerations. The relative fault of such indemnifying party
      and indemnified party shall be determined by reference to, among other
      things, whether the 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 by such indemnified
      party, and the parties' relative intent, knowledge, access to information
      and opportunity to correct or prevent such statement or omission. The
      parties hereto agree that it would not be just and equitable if
      contributions pursuant to this Section 6(d) were determined by pro rata
      allocation (even if the holders or any agents or underwriters or all of
      them were treated as one entity for such purpose) or by any other method
      of allocation which does not take account of the equitable considerations
      referred to in this Section 6(d). The amount paid or payable by an
      indemnified party as a result of the losses, claims, damages, or
      liabilities (or actions in respect thereof) referred to above shall be
      deemed to include any legal or other fees or expenses reasonably incurred
      by such indemnified party in connection with investigating or defending
      any such action or claim. Notwithstanding the provisions of this Section
      6(d), no holder shall be required to contribute any amount in excess of
      the amount by which the dollar amount of the proceeds received by such
      holder from the sale of any Registrable Securities (after deducting any
      fees, discounts and commissions applicable thereto) exceeds the amount of
      any damages which such holder has otherwise been required to pay by reason
      of such untrue or alleged untrue statement or omission or alleged
      omission, and no underwriter shall be required to contribute any amount in
      excess of the amount by which the total price at which the Registrable
      Securities underwritten by it and distributed to the public were offered
      to the public exceeds the amount of any damages which such underwriter 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' and any underwriters'
      obligations in this Section 6(d) to contribute shall be several in
      proportion to the principal amount of Registrable Securities registered or
      underwritten, as the case may be, by them and not joint. For purposes of
      this Section 6(d), each person, if any, who controls such indemnified
      party within the meaning of the Securities Act or the Exchange Act shall
      have the same rights to contribution as such indemnified party


                                       20


      and each person, if any, who controls the Company within the meaning of
      the Securities or the Exchange Act shall have the same rights to
      contribution as the Company.

            (e) The obligations of the Company and each of the Guarantors under
      this Section 6 shall be in addition to any liability which the Company or
      any of the Guarantors may otherwise have and shall extend, upon the same
      terms and conditions, to each officer, director and partner of each
      holder, agent and underwriter and each person, if any, who controls any
      holder, agent or underwriter within the meaning of the Securities Act; and
      the obligations of the holders and any agents or underwriters contemplated
      by this Section 6 shall be in addition to any liability which the
      respective holder, agent or underwriter may otherwise have and shall
      extend, upon the same terms and conditions, to each officer and director
      of the Company or any of the Guarantors (including any person who, with
      his consent, is named in any registration statement as about to become a
      director of the Company or any of the Guarantors) and to each person, if
      any, who controls the Company within the meaning of the Securities Act.

      7. Underwritten Offerings.

            (a) Selection of Underwriters. If any of the Registrable Securities
      covered by the Shelf Registration are to be sold pursuant to an
      underwritten offering, the managing underwriter or underwriters thereof
      shall be designated by Electing Holders holding at least a majority in
      aggregate principal amount of the Registrable Securities to be included in
      such offering, provided that such designated managing underwriter or
      underwriters is or are reasonably acceptable to the Company.

            (b) Participation by Holders. Each holder of Registrable Securities
      hereby agrees with each other such holder that no such holder may
      participate in any underwritten offering hereunder unless such holder (i)
      agrees to sell such holder's Registrable Securities on the basis provided
      in any underwriting arrangements approved by the persons entitled
      hereunder to approve such arrangements and (ii) completes and executes all
      questionnaires, powers of attorney, indemnities, underwriting agreements
      and other documents reasonably required under the terms of such
      underwriting arrangements.

      8. Rule 144.

            The Company covenants to the holders of Registrable Securities that
to the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Securities Act (including the reports under Section 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the
Commission under the Securities Act) and the rules and regulations adopted by
the Commission thereunder, and shall take such further action as any holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar or successor rule or regulation hereafter adopted
by the Commission. Upon the request, in writing, of any holder of Registrable
Securities in connection with that holder's sale pursuant to Rule 144, the
Company shall deliver to such holder a written statement as to whether it has
complied with such requirements.


                                       21


      9. Miscellaneous.

            (a) No Inconsistent Agreements. The Company represents, warrants,
      covenants and agrees that it has not granted, and shall not grant, on or
      after the date of this Exchange and Registration Rights Agreement,
      registration rights with respect to its securities which would be
      inconsistent with the rights granted to holders of Registrable Securities
      in this Exchange and Registration Rights Agreement.

            (b) Specific Performance. The parties hereto acknowledge that there
      would be no adequate remedy at law if the Company fails to perform any of
      its obligations hereunder and that the Purchasers and the holders from
      time to time of the Registrable Securities may be irreparably harmed by
      any such failure, and accordingly agree, that the Purchasers and such
      holders, in addition to any other remedy to which they may be entitled at
      law or in equity, may obtain such relief as may be required to
      specifically enforce the obligations of the Company under this Exchange
      and Registration Rights Agreement in accordance with the terms and
      conditions of this Exchange and Registration Rights Agreement, in any
      court of the United States or any State thereof having jurisdiction.

      other communications hereunder shall be in writing and shall be deemed to

      certified mail, postage prepaid, return receipt requested) as follows: If
      to the Company, to it at 259 North Radnor-Chester Road, Suite 100, Radnor,
      Pennsylvania 19087-5283, and if to a holder, to the address of such holder
      set forth in the security register or other records of the Company, or to
      such other address as the Company or any such holder may have furnished to

      of address shall be effective only upon receipt.

            (d) Parties in Interest. All the terms and provisions of this
      Exchange and Registration Rights Agreement shall be binding upon, shall
      inure to the benefit of and shall be enforceable by the parties hereto and
      the holders from time to time of the Registrable Securities and the
      respective successors and assigns of the parties hereto and such holders.
      In the event that any transferee of any holder of Registrable Securities
      shall acquire Registrable Securities, in any manner, whether by gift,
      bequest, purchase, operation of law or otherwise, such transferee shall,
      without any further writing or action of any kind, be deemed a beneficiary
      hereof for all purposes and such Registrable Securities shall be held
      subject to all of the terms of this Exchange and Registration Rights
      Agreement, and by taking and holding such Registrable Securities such
      transferee shall be entitled to receive the benefits of, and be
      conclusively deemed to have agreed to be bound by all of the applicable
      terms and provisions of this Exchange and Registration Rights Agreement.
      If the Company shall so request, any such successor, assign or transferee
      shall agree in writing to acquire and hold the Registrable Securities
      subject to all of the applicable terms hereof.

            (e) Survival. The respective indemnities, agreements,
      representations, warranties and each other provision set forth in this
      Exchange and Registration Rights Agreement or made pursuant hereto shall
      remain in full force and effect regardless of any investigation (or
      statement as to the results thereof) made by or on behalf of any holder of
      Registrable Securities, any director, officer or partner of such holder,
      any agent or underwriter or any director, officer or partner thereof, or
      any controlling person of any of the foregoing, and shall survive delivery
      of and payment for the Registrable Securities pursuant to the


                                       22

      Securities by such holder and the consummation of an Exchange Offer.

            (f) Governing Law. This Exchange and Registration Rights Agreement
      shall be governed by and construed in accordance with the laws of the
      State of New York.

      paragraphs of this Exchange and Registration Rights Agreement are inserted

      Securities at the time outstanding. Each holder of any Registrable
      Securities at the time or thereafter outstanding shall be bound by any

      thereof set forth in Section 9(c) above and at the office of the Trustee
      under the Indenture.

      such respective counterparts shall together constitute one and the same
      instrument.

                                     (Date)

Reference is hereby made to the Exchange and Registration Rights Agreement (the
"Exchange and Registration Rights Agreement") between Airgas, Inc. (the
"Company") and the Purchasers named therein. Pursuant to the Exchange and
Registration Rights Agreement, the Company has filed with the United States
Securities and Exchange Commission (the "Commission") a registration statement

resale under Rule 415 of the Securities Act of 1933, as amended (the "Securities
Act"), of the Company's [ ]% Senior Subordinated Notes due 2011 (the
"Securities"). A copy of the Exchange and Registration Rights Agreement is
attached hereto. All capitalized terms not otherwise defined herein shall have
the meanings ascribed thereto in the Exchange and Registration Rights Agreement.

Each beneficial owner of Registrable Securities (as defined below) is entitled
to have the Registrable Securities beneficially owned by it included in the
Shelf Registration Statement. In order to have Registrable Securities included
in the Shelf Registration Statement, this Notice of Registration Statement and
Selling Securityholder Questionnaire ("Notice and Questionnaire") must be

of Registrable Securities who do not complete, execute and return this Notice
and Questionnaire by such date (i) will not be named as selling securityholders
in the Shelf Registration Statement and (ii) may not use the Prospectus forming

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

The term "Registrable Securities" is defined in the Exchange and Registration
Rights Agreement.

      assume. The Selling Securityholder may also sell Registrable Securities
      short and deliver Registrable Securities to close out such short
      positions, or loan or pledge Registrable Securities to broker-dealers that
      in turn may sell such securities.
