     the Issuers shall file with the SEC, no later than the Filing Date, a
     Registration Statement (the "Exchange Offer Registration Statement") on an
                                  -------------------------------------

     to the Indenture (other than such changes to the Indenture or any such
     identical trust indenture as are necessary to comply with the TIA) and
     which, in either case, has been qualified under the TIA.  The Exchange
     Offer shall comply with all applicable tender offer rules and regulations
     under the Exchange Act and other applicable law. The Issuers shall use
     their reasonable best efforts to (x) cause the Exchange Offer Registration
     Statement to be declared effective under the Securities Act on or before
     the Effectiveness Date; (y) keep the Exchange Offer open for at least 20
     business days (or longer if required by applicable law) after the date that
     notice of the Exchange Offer is mailed to Holders; and (z) consummate the
     Exchange Offer on or prior to the 45th day following the date on which the
     Exchange Offer Registration Statement is declared effective by the SEC.

     the Exchange Offer Registration Statement is initially declared effective
     by the SEC, the Exchange Offer or the issuance of the Exchange Notes

     or requirement of the SEC or any other governmental agency or court, the
     Exchange Offer Registration Statement shall be deemed not to have become
     effective for purposes of this Agreement.

          Each Holder that participates in the Exchange Offer will be required,
as a condition to its participation in the Exchange Offer, to represent to the
Company in writing (which may be contained in the applicable letter of
transmittal) that any Exchange Notes to be received by it will be acquired in
the ordinary course of its business, that at the time of the consummation of the
Exchange Offer such Holder will have no arrangement or understanding with any
Person to participate in the distribution of the Exchange Notes in violation of
the provisions of the Securities Act, that such Holder is not an affiliate of
the Company within the meaning of the Securities Act and that such Holder is not
acting on behalf of a Person who could not make the foregoing representations.

          Upon consummation of the Exchange Offer in accordance with this
Section 2, the provisions of this Agreement shall continue to apply, mutatis
                                                                     -------

Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and Exchange
Notes held by Participating Broker-Dealers (as defined), and the Issuers shall
have no further obligation to register Registrable Notes (other than Private
Exchange Notes and other than in respect of any Exchange Notes as to which
clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof.

          No securities other than the Exchange Notes and Guarantees shall be
included in the Exchange Offer Registration Statement.

          (b)  The Issuers shall include within the Prospectus contained in the
     Exchange Offer Registration Statement a section entitled "Plan of
     Distribution," reasonably acceptable to the Initial Purchasers, 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 brokerdealer in the
     Exchange Offer (a "Participating Broker-Dealer"), whether such positions or
                        ---------------------------                             
     policies have been publicly disseminated by the staff of the SEC or such
     positions or policies represent the prevailing views of the staff of the
     SEC.  Such "Plan of Distribution" section shall also expressly permit, 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 permitted by
     applicable policies and regulations of the SEC, all Participating Broker-
     Dealers, and include a statement describing the means by which
     Participating Broker-Dealers may resell the Exchange Notes in compliance
     with the Securities Act.

          The Issuers shall use their reasonable best efforts to keep the
Exchange Offer Registration Statement effective and to amend and supplement the
Prospectus contained 

 
                                                                               6

                                                                  --------  
however, that such period shall not be required to exceed 90 days after such 
- -------                                           
Exchange Offer Registration Statement is declared effective (or such longer
period if extended pursuant to the last paragraph of Section 5 hereof) (the
"Applicable Period").
 -----------------   

          If, prior to consummation of the Exchange Offer, any Holder holds any
Notes acquired by it that have, or that are reasonably likely to be determined
to have, the status of an unsold allotment in an initial distribution, or any
Holder is not entitled to participate in the Exchange Offer, the Company upon
the request of any such Holder shall simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to any such Holder, in
exchange (the "Private Exchange") for such Notes held by any such Holder, a like
               ----------------                                                 
principal amount of notes (the "Private Exchange Notes") of the Company,
                                ----------------------                  
guaranteed by the Guarantors, that are identical in all material respects to the
Exchange Notes except for the placement of a restrictive legend on such Private
Exchange Notes.  The Private Exchange Notes shall be issued pursuant to the same
indenture as the Exchange Notes and bear the same CUSIP number as the Exchange
Notes.

          In connection with the Exchange Offer, the Issuers shall:

               (i)  mail, or cause to be mailed, to each Holder of record
     entitled to participate in the Exchange Offer a copy of the Prospectus
     forming part of the Exchange Offer Registration Statement, together with an
     appropriate letter of transmittal and related documents;

               (ii)  utilize the services of a depositary for the Exchange Offer
     with an address in the Borough of Manhattan, The City of New York;

               (iii)  permit Holders to withdraw tendered 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

               (iv)  otherwise comply in all material respects with all
     applicable laws, rules and regulations.

          As soon as practicable after the close of the Exchange Offer and the
Private Exchange, if any, the Issuers shall:

          (i)    accept for exchange all Registrable Notes validly tendered and
     not validly withdrawn pursuant to the Exchange Offer and the Private
     Exchange, if any;

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

 
                                                                               7

          (iii)  cause the Trustee to authenticate and deliver promptly to each
     Holder of 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.

          The Exchange Offer and the Private Exchange shall not be subject to
any conditions, other than that (i) the Exchange Offer or Private Exchange, as
the case may be, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) no action or proceeding shall have
been instituted or threatened in any court or by any governmental agency which
might prohibit or materially impair the ability of the Issuers to proceed with
the Exchange Offer or the Private Exchange, and no material adverse development
shall have occurred in any existing action or proceeding with respect to the
Issuers and (iii) all govern mental approvals shall have been obtained, which
approvals the Issuers deem necessary for the consummation of the Exchange Offer
or Private Exchange. In addition, each broker-dealer that desires to participate
in the Exchange Offer and to receive Exchange Notes will be required to
represent that the Notes being tendered by such broker-dealer were acquired in
ordinary trading or market-making activities and not in transactions directly
with any Issuer or Affiliate thereof. A broker-dealer that is not able to make
the foregoing representation will not be permitted to participate in the
Exchange Offer.

          The Exchange Notes and the Private Exchange Notes shall be issued
under (i) the Indenture or (ii) an indenture identical in all material respects
to the Indenture and which, in either case, has been qualified under the TIA or
is exempt from such qualification and shall provide that the Exchange Notes (but
not the Private Exchange Notes) shall not be subject to the transfer
restrictions set forth in the Indenture. The Indenture or such indenture shall
provide that the Exchange Notes, the Private Exchange Notes and the Notes shall
vote and consent together on all matters as one class and that none of the
Exchange Notes, the Private Exchange Notes or the Notes will have the right to
vote or consent as a separate class on any matter.

          (c)  If, (i) because of any change in law or in currently prevailing
     interpretations,of the staff of the SEC, the Issuers are not permitted to
     effect the Exchange Offer, (ii) the Exchange Offer is not consummated
     within 195 days of the Issue Date, (iii) any holder of Private Exchange
     Notes so requests in writing to the Company within 60 days after the
     consummation of the Exchange Offer, or (iv) in the case of any Holder that
     participates in the Exchange Offer, such Holder does not receive Exchange
     Notes on the date of the exchange that may 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 or an "underwriter",
     each within the meaning of the Securities Act), then in the case of each of
     clauses (i) to and including (iv) of this sentence, the Company shall
     promptly deliver to the Holders and the Trustee written notice thereof (the
     "Shelf Notice") and shall file a Shelf Registration pursuant to Section 3
      ------------                                                            
     hereof.

          3.  Shelf Registration
              ------------------

 
                                                                               8

          If at any time a Shelf Notice is delivered as contemplated by Section
2(c) hereof, then:

          (a)  Shelf Registration.  The Issuers, as promptly as practicable,
               ------------------                                           
     shall 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 not exchanged in the Exchange Offer, Private Exchange Notes and
     Exchange Notes as to which Section 2(c)(iv) is applicable (the "Initial
                                                                     -------
     Shelf Registration"). The Issuers shall use their reasonable best efforts 
     -------------------                                               
     to file with the SEC the Initial Shelf Registration on or before the
     applicable Filing Date. The Initial Shelf Registration shall be on an
     appropriate form permitting registration of such Registrable Notes for
     resale by Holders in the manner or manners designated by them (including,
     without limitation, one or more underwritten offerings). The Issuers shall
     not permit any securities other than the Registrable Notes to be included
     in the Initial Shelf Registration or any Subsequent Shelf Registration (as
     defined below).

          The Issuers shall use their reasonable best efforts to cause the
Initial Shelf Registration to be declared effective under the Securities Act on
or prior to the Effectiveness Date and to keep the Initial Shelf Registration
continuously effective under the Securities Act until the date which is two
years from the Issue Date (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, pursuant to Rule 144 or otherwise are no longer Registrable Notes
or (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; provided, however, that the Effectiveness Period in respect of the Initial
     --------  -------                                                         
Shelf Registration shall be extended to the extent required to permit dealers to
comply with the applicable prospectus delivery requirements of Rule 174 under
the Securities Act and as otherwise provided herein.  No Holder may include any
of its Registrable Notes in any Shelf Registration Statement pursuant to this
Agreement or be entitled to receive Additional Interest (as defined below)
pursuant to Section 4 hereof unless and until such Holder furnishes to the
Company, in writing, within 15 business days after receipt of a request
therefor, such information as is required by applicable law and as the Company
may reasonably request for use in connection with any Shelf Registration
Statement or Prospectus or preliminary prospectus included therein.  Each Holder
as to which any Shelf Registration Statement is being effected agrees to furnish
promptly to the Company all information required to be disclosed in order to
make information previously furnished to the Company by such Holder not
materially misleading.

          (b)  Subsequent Shelf Registrations.  If the Initial Shelf
               ------------------------------                       
     Registration or any Subsequent Shelf Registration ceases to be effective
     for any reason at any time during the Effectiveness Period (other than as
     permitted in the second paragraph of Section 3(a) above because of the sale
     of all of the securities registered thereunder), the Issuers shall use
     their reasonable best efforts to obtain the prompt withdrawal of any order
     suspending the effectiveness thereof, and in any event shall within 30 days
     of such cessation of effectiveness amend the Initial Shelf Registration in
     a manner to 

 
                                                                               9

     obtain the withdrawal of the order suspending the effectiveness thereof,
     or, in the Company's sole discretion, file an additional "shelf"
     Registration Statement pursuant to Rule 415 covering all of the Registrable
     Notes covered by and not sold under the Initial Shelf Registration or an
     earlier Subsequent Shelf Registration (each, a "Subsequent Shelf
                                                     ----------------
     Registration").  If a Subsequent Shelf Registration is filed, the
     ------------                                                     
     Issuers shall use their reasonable best efforts to cause the Subsequent
     Shelf Registration to be declared effective under the Securities Act 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
     ------------                                                               
     Registration.

          (c)  Supplements and Amendments.  The Issuers 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, if required by the Securities Act, or if
     reasonably requested by the Holders of a majority in aggregate principal
     amount of the Registrable Notes covered by such Registration Statement or
     by any underwriter of such Registrable Notes.

          4.  Additional Interest
              -------------------

          (a)  The Issuers and the Initial Purchasers agree that the Holders
     will suffer damages if the Issuers fail to fulfill their 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 agrees to pay, as liquidated damages, additional 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 Offer Registration Statement nor
          the Initial Shelf Registration has been filed on or prior to the
          applicable Filing Date or (B) notwithstanding that the Issuers have
          consummated or will consummate the Exchange Offer, the Issuers are
          required to file a Shelf Registration and such Shelf Registration is
          not filed on or prior to the Filing Date applicable thereto, then,
          commencing on the day after any such Filing Date, Additional Interest
          shall accrue on the principal amount of the Notes at a rate of 0.25%
          per annum for the first 90 days immediately following each such Filing
          Date, and such Additional Interest rate shall increase by an
          additional 0.25% per annum at the beginning of each subsequent 90-day
          period; or

               (ii) if (A) neither the Exchange Offer Registration Statement nor
          the Initial Shelf Registration is declared effective by the SEC on or
          prior to the relevant Effectiveness Date or (B) notwithstanding that
          the Issuers have consummated or will consummate the Exchange Offer,
          the Issuers are 

 
                                                                              10

          required to file a Shelf Registration and such Shelf Registration is
          not declared effective by the SEC on or prior to the Effectiveness
          Date in respect of such Shelf Registration, then, commencing on (x)
          the 151st day after the Issue Date, in the case of clause (A) or (y)
          the date after the 60th day following the applicable Filing Date in
          the case of clause (B), Additional Interest shall accrue on the
          principal amount of the Notes at a rate of 0.25% per annum for the
          first 90 days immediately following the day after such date, and such
          Additional Interest rate shall increase by an additional 0.25% per
          annum at the beginning of each subsequent 90-day period; or

               (iii)   if (A) the Issuers have not exchanged Exchange Notes for
          all Notes validly tendered in accordance with the terms of the
          Exchange Offer on or prior to the 45th day after the date on which the
          Exchange Offer Registration Statement relating thereto was declared
          effective or (B) if applicable, a Shelf Registration has been declared
          effective and such Shelf Registration ceases to be effective at any
          time during the Effectiveness Period, then Additional Interest shall
          accrue on the principal amount of the Notes at a rate of 0.25% per
          annum for the first 90 days commencing on the (x) 46th day after such
          effective date, in the case of (A) above, or (y) the day such Shelf
          Registration ceases to be effective in the case of (B) above, and such
          Additional Interest rate shall increase by an additional 0.25% per
          annum at the beginning of each such subsequent 90-day period;

provided, however, that the Additional Interest rate on the Notes may not exceed
- --------  -------                                                               
at any one time in the aggregate 1.50% per annum; provided, further, however,
                                                  --------  -------  ------- 
that (1) upon the filing of the Exchange Offer Registration Statement or a Shelf
Registration as required hereunder (in the case of clause (i) above of this
Section 4), (2) upon the effectiveness of the Exchange Offer Registration
Statement or a Shelf Registration Statement as required hereunder (in the case
of clause (ii) of this Section 4), or (3) upon the exchange of the applicable
Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of this
Section 4), or upon the effectiveness of the applicable Shelf Registration
Statement which had ceased to remain effective (in the case of (iii)(B) of this
Section 4), Additional Interest on the Notes in respect of which such events
relate 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 (a)(i), (a)(ii) or (a)(iii) of this
     Section 4 will be payable in cash semiannually on each May 15  and November
     15 (to the holders of record on the May 1 and November 1 immediately
     preceding such dates), commencing with the first such 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 Registrable 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 

 
                                                                              11

     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.  Registration Procedures
              -----------------------

          In connection with the filing of any Registration Statement pursuant
to Sections 2 or 3 hereof, the Issuers shall effect such registrations to permit
the sale of the 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 Issuers hereunder each of the
Issuers shall:

          (a)  Prepare and file with the SEC prior to the applicable Filing
     Date, a Registration Statement or Registration Statements as prescribed by
     Sections 2 or 3 hereof, and use its reasonable best efforts to cause each
     such Registration Statement to become effective and remain effective as
     provided herein; provided, however, that, if (1) such filing is pursuant to
                      --------  -------                                         
     Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer
     Registration Statement filed pursuant to Section 2 hereof 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 Issuers shall furnish to and afford the Holders of
     the Registrable Notes included in such Registration Statement or each such
     Participating Broker-Dealer, as the case may be, their counsel and the
     managing underwriters, if any, 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 prior to
     the effectiveness of such Registration Statement (in each case at least
     five business days prior to such filing, or such later date as is
     reasonable under the circumstances).  The Issuers shall not file any
     Registration Statement or Prospectus or any amendments or supplements
     thereto if the Holders of a majority in aggregate principal amount of the
     Registrable Notes included in such Registration Statement, or any such
     Participating Broker-Dealer, as the case may be, their counsel, or the
     managing underwriters, if any, shall reasonably object on a timely basis.

          (b)  Prepare and file with the SEC such amendments and post-effective
     amendments to each Shelf Registration Statement or Exchange Offer
     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 each of 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 

 
                                                                              12

     Prospectus. The Issuers shall be deemed not to have used their reasonable
     best efforts to keep a Registration Statement effective during the
     Effectiveness Period or the Applicable Period, as the case may be, relating
     thereto if any Issuer voluntarily takes any action that would result in
     selling Holders of the Registrable Notes covered thereby 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 or permitted by this Agreement.

          (c)  If(1) a Shelf Registration is filed pursuant to Section 3 hereof,
     or (2) a Prospectus contained in the Exchange Offer Registration Statement
     filed pursuant to Section 2 hereof 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 from whom the
     Company has received written notice that it will be a Participating Broker-
     Dealer in the Exchange Offer, notify the selling Holders of Registrable
     Notes, or each such Participating Broker-Dealer, as the case may be, their
     counsel and the managing underwriters, if any, promptly (but in any event
     within one day), and confirm such notice in writing, (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 under the Securities Act
     (including in such notice a written statement that any Holder may, upon
     request, obtain, at the sole expense of the Issuers, 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 preliminary 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 or resales of Exchange Notes
     by Participating Broker-Dealers the representations and warranties of the
     Issuers contained in any agreement (including any underwriting agreement)
     contemplated by Section 5(1) hereof cease to be true and correct in all
     material respects, (iv) of the receipt by any Issuer 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, it will
     not contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and that in the case of the Prospectus,
     it will not contain any untrue statement of a material fact or omit to
     state any material fact required to be stated 

 
                                                                              13

     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading, and (vi) of the
     Issuers' determination that a post-effective amendment to a Registration
     Statement would be appropriate.

          (d)  If (1) a Shelf Registration is filed pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Notes during the Applicable Period, use its reasonable 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 reasonable best efforts to obtain
     the withdrawal of any such order at the earliest possible moment.

          (e)  If a Shelf Registration is filed pursuant to Section 3 and if
     requested by the managing underwriter or underwriters (if any), the Holders
     of a majority in aggregate principal amount of the Registrable Notes being
     sold in connection with an underwritten offering or any Participating
     Broker-Dealer, (i) as promptly as practicable incorporate in a prospectus
     supplement or post-effective amendment such information as the managing
     underwriter or underwriters (if any), such Holders, any Participating
     Broker-Dealer or counsel for any of them reasonably request to be included
     therein, (ii) make all required filings of such prospectus supplement or
     such post-effective amendment as soon as practicable after an Issuer has
     received notification of the matters to be incorporated in such prospectus
     supplement or post-effective amendment, and (iii) supplement or make
     amendments to such Registration Statement.

          (f)  If (1) a Shelf Registration is filed pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Notes during the Applicable Period, furnish to each selling
     Holder of Registrable Notes and to each such Participating Broker-Dealer
     who so requests and to their respective counsel and each managing 
     underwriter, if any, at the sole expense of the Issuers, one conformed copy
     of the Registration Statement or Registration Statements and each post-
     effective amendment thereto, including financial statements and schedules,
     and, if requested, all documents incorporated or deemed to be incorporated
     therein by reference and all exhibits.

          (g)  If (1) a Shelf Registration is filed pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Notes during the Applicable Period, deliver to each selling
     Holder of Registrable Notes, or each such 

 
                                                                              14

     Participating Broker-Dealer, as the case may be, their respective counsel,
     and the underwriters, if any, at the sole expense of the Issuers, as many
     copies of the Prospectus or Prospectuses (including each form of
     preliminary prospectus) and each amendment or supplement thereto and any
     documents incorporated by reference therein as such Persons may reasonably
     request; and, subject to the last paragraph of this Section 5, the Issuers
     hereby consent to the use of such Prospectus and each amendment or
     supplement thereto by each 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.

          (h)  Prior to any public offering of Registrable Notes or any delivery
     of a Prospectus contained in the Exchange Offer Registration Statement by
     any Participating Broker-Dealer who seeks to sell Exchange Notes during
     the Applicable Period, use its reasonable 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 managing
     underwriter or 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 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 the
     managing underwriter or underwriters reasonably request in writing;
     provided, however, that where Exchange Notes held by Participating Broker-
     --------  -------                                                        
     Dealers or Registrable Notes are offered other than through an underwritten
     offering, the Issuers agree to cause their counsel to perform Blue Sky
     investigations and file registrations and qualifications required to be
     filed pursuant to this Section 5(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, however, that no Issuer shall
                                        --------  -------                      
     be required to (A) qualify generally to do business in any jurisdiction
     where it is not then so qualified, (B) take any 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 excess of a nominal
     dollar amount in any such jurisdiction where it is not then so subject.

          (i)  If a Shelf Registration is filed pursuant to Section 3 hereof,
     cooperate with the selling Holders of Registrable Notes and the managing
     underwriter or underwriters, if any, to facilitate the timely preparation
     and delivery of certificates representing Registrable Notes to be sold,
     which certificates shall not bear any restrictive legends and shall be in a
     form eligible for deposit with The Depository Trust Company; and enable
     such Registrable Notes to be in such denominations and 

 
                                                                              15

     registered in such names as the managing underwriter or underwriters, if
     any, or Holders may request.

          (j)  If (1) a Shelf Registration is filed pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Notes during the Applicable Period, upon the occurrence of
     any event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly
     as practicable prepare and (subject to Section 5(a) hereof) file with the
     SEC, at the sole expense of the Issuers, a supplement or post-effective
     amendment to the Registration Statement or a supplement to the related
     Prospectus or any document incorporated or deemed to be incorporated
     therein by reference, or file any other required document so that, as
     thereafter delivered to the purchasers of the Registrable Notes being sold
     thereunder or to the purchasers of the Exchange Notes to whom such
     Prospectus will be delivered by a Participating Broker-Dealer, any such
     Prospectus will not contain an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading. Notwithstanding the foregoing, the Issuers shall not
     be required to amend or supplement a Registration Statement, any related
     Prospectus or any document incorporated therein by reference, in the event
     that, and for a period not to exceed an aggregate of 75 days in any 
     calendar year if, (i) an event occurs and is continuing as a result of
     which the Shelf Registration would, in the Company's good faith judgment,
     contain an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, and (ii) (a) the
     Company determines in its good faith judgment that the disclosure of such
     event at such time would have a material adverse effect on the business,
     operations, condition (financial or otherwise) or prospects of the Company
     or (b) the disclosure otherwise relates to a pending material business
     transaction that has not yet been publicly disclosed or with respect to
     which financial statements or other financial information would be required
     to be included in a Registration Statement and are not yet available.

          (k)  Prior to the effective date of the first Registration Statement
     relating to the Registrable Notes, (i) provide the Trustee with
     certificates for the Registrable Notes in a form eligible for deposit with
     The Depository Trust Company and (ii) provide a CUSIP number for the
     Registrable Notes.

          (l)  In connection with any underwritten offering of Registrable Notes
     pursuant to a Shelf Registration, enter into an underwriting agreement as
     is customary in underwritten offerings of debt securities similar to the
     Notes in form and substance reasonably satisfactory to the Company and take
     all such other actions as are reasonably requested by the managing
     underwriter or underwriters in order to expedite or facilitate the
     registration or the disposition of such Registrable Notes and, in such
     connection, (i) make such representations and warranties to, and 

 
                                                                              16

     covenants with, the underwriters with respect to the business of the
     Company and the subsidiaries of the Company (including any acquired
     business, properties or entity, if applicable) and the Registration
     Statement, Prospectus and documents, if any, incorporated or deemed to be
     incorporated by reference therein, in each case, as are customarily made by
     issuers to underwriters in underwritten offerings of debt securities
     similar to the Notes, and confirm the same in writing if and when requested
     in form and substance reasonably satisfactory to the Company; (ii) obtain
     the written opinions of counsel to the Company and written updates thereof
     in form, scope and substance reasonably satisfactory to the managing
     underwriter or underwriters, addressed to the underwriters covering the
     matters customarily covered in opinions reasonably requested in
     underwritten offerings and such other matters as may be reasonably
     requested by the managing underwriter or underwriters; (iii) use its
     reasonable best efforts to obtain "cold comfort" letters and updates
     thereof in form, scope and substance reasonably satisfactory to the
     managing underwriter or underwriters from the independent public
     accountants of the Company (and, if necessary, any other independent public
     accountants of the Company, any subsidiary of the Company or of any
     business acquired by the Company for which financial statements and
     financial data are, or are required to be, included or incorporated by
     reference in the Registration Statement), addressed to each of the
     underwriters, such letters to be in customary form and covering matters of
     the type customarily covered in "cold comfort" letters in connection with
     underwritten offerings of debt securities similar to the Notes and such
     other matters as reasonably requested by the managing underwriter or
     underwriters as permitted by the Statement on Auditing Standards No. 72;
     and (iv) if an underwriting agreement is entered into, the same shall
     contain indemnification provisions and procedures no less favorable to the
     sellers and underwriters, if any, than those set forth in Section 7 hereof
     (or such other provisions and procedures acceptable to Holders of a
     majority in aggregate principal amount of Registrable Notes covered by such
     Registration Statement and the managing underwriter or underwriters or
     agents, if any). The above shall be done at each closing under such
     underwriting agreement, or as and to the extent required thereunder.

          (m)  If (1) a Shelf Registration is filed pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Notes during the Applicable Period, make available for
     inspection by any selling Holder of such Registrable Notes being sold, or
     each such Participating Broker-Dealer, as the case may be, any underwriter
     participating in any such disposition of Registrable Notes, if any, and any
     attorney, accountant or other agent retained by any such selling Holder or
     each such Participating Broker-Dealer, as the case may be, or underwriter
     (collectively, the "Inspectors"), at the offices where normally kept,
                         ----------                                       
     during reasonable business hours, all financial and other records,
     pertinent corporate documents and instruments of the Company and
     subsidiaries of the Company (collectively, the "Records") as shall be
                                                     -------              
     reasonably necessary to enable them to exercise any applicable due
     diligence responsibilities, and cause the officers, directors and employees
     of the 

 
                                                                              17

     Company and any of its subsidiaries to supply all information reasonably
     requested by any such Inspector in connection with such Registration
     Statement and Prospectus. Each Inspector shall agree in writing that it
     will keep the Records confidential and that it will not disclose any of the
     Records unless (i) the disclosure of such Records is necessary to avoid or
     correct a material misstatement or material omission in such Registration
     Statement or Prospectus, (ii) the release of such Records is ordered
     pursuant to a subpoena or other order from a court of competent
     jurisdiction, or (iii) the information in such Records has been made
     generally available to the public not in violation of any person's or
     entity's confidentiality obligations; provided, however, that prior notice
                                           --------  -------                   
     shall be provided as soon as practicable to the Company of the potential
     disclosure of any information by such Inspector pursuant to clauses (i) or
     (ii) of this sentence to permit the Company to obtain a protective order
     (or waive the provisions of this paragraph (m)) and that such Inspector
     shall take such actions as are reasonably necessary to protect the
     confidentiality of such information (if practicable) to the extent such
     action is otherwise not inconsistent with, an impairment of or in
     derogation of the rights and interests of the Holder or any Inspector.

          (n)  Provide an indenture trustee for the Registrable Notes or the
     Exchange Notes, as the case may be, and cause the Indenture or the trust
     indenture provided for in Section 2(a) hereof, as the case may be, to be
     qualified under the TIA not later than the effective date of the first
     Registration Statement relating to the Registrable Notes; and in connection
     therewith, cooperate with the trustee under any such indenture and the
     Holders of the Registrable Notes, 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 reasonable 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.

          (o)  Comply with all applicable rules and regulations of the SEC and
     make generally available to its securityholders with regard to any
     applicable Registration Statement, a consolidated earnings statement
     satisfying the provisions of Section 11(a) of the Securities Act and Rule
     158 thereunder (or any similar rule promulgated under the Securities Act)
     no later than 60 days after the end of any fiscal quarter (or 120 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.

          (p)  If the Exchange Offer or a Private Exchange is to be consummated,
     upon delivery of the Registrable Notes by Holders to the Company (or to
     such other Person as directed by the Issuer) in exchange for the Exchange
     Notes or the Private Exchange Notes, as the case may be, the Company shall
     mark, or cause to be 

 
                                                                              18

     marked, on such Registrable Notes that such Registrable Notes are being
     canceled in exchange for the Exchange Notes or the Private Exchange Notes,
     as the case may be; in no event shall such Registrable Notes be marked as
     paid or otherwise satisfied.

          (q)  Cooperate with each seller of Registrable Notes covered by any
     Registration Statement and each underwriter, if any, participating in the
     disposition of such Registrable Notes and their respective counsel in
     connection with any filings required to be made with the National
     Association of Securities Dealers, Inc. (the "NASD").
                                                   ----   

          (r)  Use its reasonable best efforts to take all other steps
     reasonably necessary to effect the registration of the Exchange Notes
     and/or Registrable Notes covered by a Registration Statement contemplated
     hereby.

          The Company may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such Registrable Notes as the
Company may, from time to time, reasonably request.  The Company may exclude
from such registration the Registrable Notes of any seller so long as such
seller fails to furnish such information within a reasonable time after
receiving such request.  Each seller as to which any Shelf 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 to the
Company by such seller not materially misleading.

          If any such Registration Statement refers to any Initial Purchaser by
name or otherwise as the holder of any securities of the Company, then such
Initial Purchaser shall have the right to require (i) the insertion therein of
language, in form and substance reasonably satisfactory to such Initial
Purchaser and the Company, to the effect that the holding by such Initial
Purchaser of such securities is not to be construed as a recommendation by such
Initial Purchaser of the investment quality of the securities covered thereby
and that such holding does not imply that such Initial Purchaser will assist in
meeting any future financial requirements of the Company, or (ii) in the event
that such reference to such Initial Purchaser by name or otherwise is not
required by the Securities Act or any similar federal statute then in force, the
deletion of the reference to such Initial Purchaser in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder of Registrable Notes and each Participating Broker-Dealer
agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold
by such Participating Broker-Dealer, as the case may be, that, upon actual
receipt of any notice from the Company of the happening of any event of the
kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such
Holder will forthwith discontinue disposition of such Registrable Notes covered
by such Registration Statement or Prospectus or Exchange Notes to be sold by
such Holder or Participating Broker-Dealer, as the case may be, until such
Holder's or Participating Broker-Dealer's receipt of the copies of the
supplemented or 

 
                                                                              19

amended Prospectus contemplated by Section 5(j) hereof, or until it is advised
in writing (the "Advice") by the Company that the use of the applicable 
                 ------                                  
Prospectus may be resumed, and has received copies of any amendments or
supplements thereto. In the event that the Company 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 and
including the date when each seller of Registrable Notes covered by such
Registration Statement or Exchange Notes to be sold by such Participating 
Broker-Dealer, as the case may be, shall have received (x) the copies of the
supplemented or amended Prospectus contemplated by Section 5(j) hereof or (y)
the Advice.

          6.  Registration Expenses
              ---------------------

          All fees and expenses incident to the performance of or compliance

     statements therein, in the case of the Prospectus in light of the
     circumstances under which they were made, not misleading, except insofar as
                                                               ------
     such losses, claims, damages or liabilities are caused by any untrue
     statement or omission or alleged untrue statement or omission made in
     reliance upon and in conformity with information relating to any
     Participant furnished to the Company in writing by such Participant
     expressly for use therein and with respect to any preliminary Prospectus,
     to the extent that any such loss, claim, damage or liability arises solely
     from the fact that any Participant sold Notes to a person to whom there was
     not sent or given a copy of the Prospectus (as amended or supplemented) at
     or prior to the written confirmation of such sale if the Company shall have
     previously furnished copies thereof to the Participant in accordance
     herewith and the Prospectus (as amended or supplemented) would have
     corrected any such untrue statement or omission.

          (b)  Each Participant agrees, severally and not jointly, to indemnify
     and hold harmless the Issuers, their respective affiliates, officers,
     directors, representatives, employees and agents of each Issuer and each
     Person who controls each Issuer within the meaning of Section 15 of the
     Securities Act or Section 20 of the Exchange Act to the same extent (but on
     a several, and not joint, basis) as the foregoing indemnity from the
     Issuers to each Participant, but only with reference to information
     relating to such Participant furnished to the Company in writing by such
     Participant expressly for use in any Registration Statement or Prospectus,
     any amendment or supplement thereto, or any preliminary prospectus.  The
     liability of any Participant under this paragraph shall in no event exceed
     the proceeds received by such Participant from sales of Registrable Notes
     or Exchange Notes giving rise to such obligations.

 
                                                                              21

          (c)  If any suit, action, proceeding (including any governmental or
     regulatory investigation), claim or demand shall be brought or asserted
     against any Person in respect of which indemnity may be sought pursuant to
     either of the two preceding paragraphs, such Person (the "Indemnified
                                                               -----------
     Person") shall promptly notify the Persons against whom such indemnity may
     ------                                                                    
     be sought (the "Indemnifying Persons") in writing, and the Indemnifying
                     --------------------                                   
     Persons, upon request of the Indemnified Person, shall retain counsel
     reasonably satisfactory to the Indemnified Person to represent the
     Indemnified Person and any others the Indemnifying Persons may reasonably
     designate in such proceeding and shall pay the fees and expenses actually
     incurred by such counsel related to such proceeding; provided, however,
                                                          --------  ------- 
     that the failure to so notify the Indemnifying Persons (i) will not
     relieve it from any liability under paragraph (a) or (b) above unless and
     to the extent such failure results in the forfeiture by the Indemnifying
     Person of substantial rights and defenses and (ii) will not, in any event,
     relieve the Indemnifying Person from any obligations to any Indemnified
     Person other than the indemnification obligation provided in paragraphs
     (a) and (b) above.  In any such proceeding, any Indemnified Person shall
     have the right to retain its own counsel, but the fees and expenses of such
     counsel shall be at the expense of such Indemnified Person unless (i) the
     Indemnifying Persons and the Indemnified Person shall have mutually agreed
     to the contrary, (ii) the Indemnifying Persons shall have failed within a
     reasonable period of time to retain counsel reasonably satisfactory to the
     Indemnified Person or (iii) the named parties in any such proceeding
     (including any impleaded parties) include both any Indemnifying Person and
     the Indemnified Person or any affiliate thereof and representation of both
     parties by the same counsel would be inappropriate due to actual or
     potential differing interests between them. It is understood that the
     Indemnifying Persons shall not, in connection with such proceeding or
     separate but substantially similar related proceeding in the same
     jurisdiction arising out of the same general allegations, be liable for the
     fees and expenses of more than one separate firm (in addition to any local
     counsel) for all Indemnified Persons, and that all such fees and expenses
     shall be reimbursed promptly as they are incurred. Any such separate firm
     for the Participants and such control Persons of Participants shall be
     designated in writing by Participants who sold a majority in interest of
     Registrable Notes and Exchange Notes sold by all such Participants and
     shall be reasonably acceptable to the Company, and any such separate firm
     for the Issuers, their affiliates, officers, directors, representatives,
     employees and agents and such control Persons of such Issuer shall be
     designated in writing by such Issuer and shall be reasonably acceptable to
     the Holders.

          The Indemnifying Persons shall not be liable for any settlement of any
proceeding effected without its prior written consent (which consent shall not
be unreasonably withheld or delayed), but if settled with such consent or if
there be a final non-appealable judgment for the plaintiff for which the
Indemnified Person is entitled to indemnification pursuant to this Agreement,
each of the Indemnifying Persons agrees to indemnify and hold harmless each
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment.  No Indemnifying Person shall, without the prior written
consent of the Indemnified Persons (which consent shall not be unreasonably
withheld or delayed), 

 
                                                                              22

effect any settlement or compromise of any pending or threatened proceeding in
respect of which any Indemnified Person is or could have been a party, or
indemnity could have been sought hereunder by such Indemnified Person, unless
such settlement (A) includes an unconditional written release of such
Indemnified Person, in form and substance reasonably satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of such Indemnified Person.

          (d)  If the indemnification provided for in the first and second
     paragraphs of this Section 7 is for any reason unavailable to, or
     insufficient to hold harmless, an Indemnified Person in respect of any
     losses, claims, damages or liabilities referred to therein, then each
     Indemnifying Person under such paragraphs, in lieu of indemnifying such
     Indemnified Person thereunder and in order to provide for just and
     equitable contribution, shall contribute to the amount paid or payable by
     such Indemnified Per son as a result of such losses, claims, damages or
     liabilities in such proportion as is appropriate to reflect (i) the
     relative benefits received by the Indemnifying Person or Persons on the one
     hand and the Indemnified Person or Persons on the other from the offering
     of the Notes or (ii) if the allocation provided by the foregoing clause (i)
     is not permitted by applicable law, not only such relative benefits but
     also the relative fault of the Indemnifying Person or Persons on the one
     hand and the Indemnified Person or Persons on the other in connection with
     the statements or omissions or alleged statements or omissions that
     resulted in such losses, claims, damages or liabilities (or actions in
     respect thereof) as well as any other relevant equitable considerations.
     The relative fault of the parties shall be determined by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by the Issuers on the one hand or such
     Participant or such other Indemnified Person, as the case may be, on the
     other, the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission, and any
     other equitable considerations appropriate in the circumstances.

          (e)  The parties agree that it would not be just and equitable if
     contribution pursuant to this Section 7 were determined by pro rata
                                                                --- ----
     allocation (even if the Participants were treated as one entity for such
     purpose) or by any other method of allocation that does not take account of
     the equitable considerations referred to in the immediately preceding
     paragraph.  The amount paid or payable by an Indemnified Person as a result
     of the losses, claims, damages, judgments, liabilities and expenses
     referred to in the immediately preceding paragraph shall be deemed to
     include, subject to the limitations set forth above, any reasonable legal
     or other expenses actually incurred by such Indemnified Person in
     connection with investigating or defending any such action or claim.
     Notwithstanding the provisions of this Section 7, in no event shall a
     Participant be required to contribute any amount in excess of the amount by
     which proceeds received by such Participant from sales of Registrable Notes
     or Exchange Notes, as the case may be, exceeds the amount of any damages
     that such Participant has otherwise been required to pay or has paid by
     reason of 

 
                                                                              23

     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.

          (f)  Any losses, claims, damages, liabilities or expenses for which an
     indemnified party is entitled to indemnification or contribution under
     this Section 7 shall be paid by the Indemnifying Person to the Indemnified
     Person as such losses, claims, damages, liabilities or expenses are
     incurred.  The indemnity and contribution agreements contained in this
     Section 7 and the representations and warranties of the Issuers set forth
     in this Agreement shall remain operative and in full force and effect,
     regard less of (i) any investigation made by or on behalf of any Holder or
     any person who controls a Holder, the Issuer, its directors, officers,
     employees or agents or any person controlling an Issuer, and (ii) any
     termination of this Agreement.

          (g)  The indemnity and contribution agreements contained in this
     Section 7 will be in addition to any liability which the Indemnifying
     Persons may otherwise have to the Indemnified Persons referred to above.

          8.  Rules 144 and 144A
              ------------------

          Each of the Issuers covenants and agrees that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and,
if at any time such Issuer is not required to file such reports, such Issuer
will, upon the request of any Holder or beneficial owner of Registrable Notes,
make available such information necessary to permit sales pursuant to Rule 144A
under the Securities Act.  Each of the Issuers further covenants and agrees, for
so long as any Registrable Notes remain outstanding that it will make available
any information as any Holder of Registrable Notes may reasonably request, all
to the extent required from time to time to enable such holder to sell
Registrable Notes without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144(k) and Rule 144A under the
Securities Act, as such Rules may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the SEC.

          9.  Underwritten Registrations
              --------------------------

          If any of the Registrable Notes covered by any Shelf Registration are
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 and shall be reasonably acceptable to the
Issuer.

 
                                                                              24

          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.

          10.  Miscellaneous
               -------------

          (a)  No Inconsistent Agreements.  The Issuers have not, as of the date
               --------------------------                                       
     hereof, and the Issuers shall not, after the date of this Agreement, enter
     into any agreement with respect to any of its securities that is
     inconsistent with the rights granted to the Holders of Registrable Notes in
     this Agreement or otherwise conflicts with the provisions hereof.  The
     rights granted to the Holders hereunder do not in any way conflict with and
     are not inconsistent with the rights granted to the holders of the Issuers'
     other issued and outstanding securities under any such agreements.  The
     Issuers will not enter into any agreement with respect to any of their
     securities which will grant to any Person piggy-back registration rights
     with respect to any Registration Statement.

          (b)  Amendments and Waivers.  The provisions of this Agreement may not
               ----------------------                                           
     be amended, modified or supplemented, and waivers or consents to departures
     from the provisions hereof may not be given, otherwise than with the prior
     written consent of (I) the Company and (II)(A) the Holders of not less than
     a majority in aggregate principal amount of the then outstanding
     Registrable Notes and (B) in circumstances that would materially adversely
     affect the Participating Broker-Dealers, the Participating Broker-Dealers
     holding not less than a majority in aggregate principal amount of the
     Exchange Notes held by all Participating Broker-Dealers; provided, however,
                                                              --------  -------
     that Section 7 and this Section 10(c) may not be amended, modified or
     supplemented without the prior written consent of each Holder and each
     Participating Broker-Dealer (including any person who was a Holder or
     Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the
     case may be, disposed of pursuant to any Registration Statement) affected
     by any such amendment, modification or supplement. 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 sold pursuant to a
     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 sold pursuant to such Registration
     Statement.

          (c)  Notices.  All notices and other communications (including,
               -------

     reference only and shall not limit or otherwise affect the meaning hereof.

 
                                                                              26

          (g)  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
               -------------                                                    
     IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO

     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 reasonable 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

     Notes is required hereunder, Registrable Notes held by the Company or its

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