2.   EXCHANGE OFFER

          (a)    The Company agrees to file with the SEC on or before the Filing
Date an offer to exchange (the "Exchange Offer") any and all of the Registrable
                                --------------                                 
Securities for a like aggregate principal amount of senior subordinated debt
securities of the Company that are identical to the Notes (the "Exchange
                                                                --------
Securities") (and that are entitled to the benefits of a trust indenture that is
----------                                                                      
identical to the Indenture (other than such changes as are necessary to comply
with any requirements of the SEC to effect or maintain the qualification of such
trust indenture under the TIA) and that has been qualified under the TIA),
except that the Exchange Securities shall have been registered pursuant to an
effective Registration Statement under the Securities Act and shall contain no
restrictive legend thereon.  The Exchange Offer will be registered under the
Securities Act on the appropriate form (the "Exchange Offer Registration
                                             ---------------------------
Statement") and will comply with all applicable tender offer rules and
---------                                                             
regulations under the Exchange Act.  The Company agrees to use its commercially
reasonable best efforts (i) to cause the Exchange Offer Registration Statement
to become effective and to commence the Exchange Offer on or prior to the
Effectiveness Date, (ii) to keep the Exchange Offer open for 20 business days
(or longer if required by applicable law) (the last day of such period, the
"Expiration Date") and (iii) to exchange Exchange Securities for all Notes
 ---------------                                                          
validly tendered and not withdrawn pursuant to the Exchange Offer on or prior to
the fifth day following the Expiration Date.

          Each Holder who participates in the Exchange Offer will be deemed to
represent that any Exchange Securities 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 with any person to
participate in the distribution of the Exchange Securities in violation of the
provisions of the Securities Act, and that such Holder is not an affiliate of
the Company within the meaning of the Securities Act.

          Upon consummation of the Exchange Offer in accordance with this
Section 2, the provisions of this Agreement shall continue to apply, mutatis
mutandis, solely with respect to Registrable Securities that are Private
Exchange Securities, Exchange Securities to which Section 2(c)(v) is applicable
and Exchange Securities held by Participating Broker-Dealers, and the Company
shall have no further obligation to register Registrable Securities (other than
Private Exchange Securities and other than Exchange Securities as to which
Section 
<PAGE>
 
                                      -5-

2(c)(v) hereof applies) pursuant to Section 3 of this Agreement. No securities
other than the Exchange Securities shall be included in the Exchange Offer
Registration Statement.

          (b)    The Company 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 (and publicly disseminated) 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 Securities received by
such broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"). Such
                                             ---------------------------
"Plan of Distribution" section shall also allow the use of the prospectus by all
persons subject to the prospectus delivery requirements of the Securities Act,
including all Participating Broker-Dealers, and include a statement describing
the means by which Participating Broker-Dealers may resell the Exchange
Securities.

          The Company shall use its commercially reasonable best efforts to keep
the Exchange Offer Registration Statement effective and to amend and supplement
the Prospectus contained therein in order to permit such Prospectus to be
lawfully delivered by all persons subject to the prospectus delivery
requirements of the Securities Act for at least 180 days following the first
bona fide offering of securities under such Registration Statement (or such
shorter time as such persons must comply with such requirements in order to
resell the Exchange Securities) (the "Applicable Period").
                                      -----------------   

          If, prior to consummation of the Exchange Offer, any Initial Purchaser
holds any Notes acquired by it and having, or which are reasonably likely to be
determined to have, the status of an unsold allotment in the initial
distribution, the Company upon the request of such Initial Purchaser shall,
simultaneously with the delivery of the Exchange Securities in the Exchange
Offer, issue and deliver to such Initial Purchaser, in exchange (the "Private
                                                                      -------
Exchange") for the Notes held by such Initial Purchaser, a like principal amount
--------                                                                        
of debt securities of the Company that are identical to the Exchange Securities
(the "Private Exchange Securities") (and which are issued pursuant to the same
      ---------------------------                                             
indenture as the Exchange Securities) (except for the placement of a restrictive
legend on such Private Exchange Securities). The Private Exchange Securities
shall bear the same CUSIP number as the Exchange Securities. Interest on the
Exchange Securities and Private Exchange Securities will accrue from the last
interest payment date on which interest was paid on the Notes surrendered in
exchange therefor or, if no interest has been paid on the Notes, from the Issue
Date.

          Any indenture under which the Exchange Securities or the Private
Exchange Securities will be issued shall provide that the holders of any of the
Exchange Securities and the Private Exchange Securities will vote and consent
together on all matters to which such holders are entitled to vote or consent as
one class and that none of the holders of the Exchange Securities and the
Private Exchange Securities 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 Company reasonably determined in
good faith, after consultation with counsel, that it is not permitted to effect
the Exchange Offer, (ii) the Exchange Offer is not commenced  on or prior to the
Effectiveness Date, (iii)  the Exchange Offer is, for any reason, not
consummated on or prior to the 165th day after the Closing Date, (iv) any Holder
of Private Exchange Securities so requests, or (v) in the case of any Holder
that participates in the Exchange Offer, such Holder does not receive Exchange
Securities on the date of the exchange that may be sold without restriction
under state and federal securities laws (the occurrence of any such event, a
"Shelf Registration Event"), then, in the case of each of clauses (i) to and
 ------------------------                                                   
including (v) of this sentence, the Company shall promptly deliver to the
Holders and the Trustee notice thereof (the "Shelf Notice") and shall thereafter
                                             ------------

3.   SHELF REGISTRATION

          If a Shelf Registration Event has occurred (and whether or not an
Exchange Offer Registration Statement has been filed with the SEC or has become
effective, or the Exchange Offer has been consummated), then:

          (a)    Initial Shelf Registration Statement. The Company shall
promptly prepare and 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 Securities (the "Initial Shelf Registration Statement"). The Company
                             ------------------------------------
shall file with the SEC the Initial Shelf Registration Statement on or prior to
the Filing Date. The Initial Shelf Registration Statement shall be on Form S-1
or another appropriate form if available, permitting registration of such
Registrable Securities for resale by such holders in the manner designated by
them (including, without limitation, in one or more underwritten offerings). The
Company shall not permit any securities other than the Registrable Securities to
be included in the Initial Shelf Registration Statement or any Subsequent Shelf
Registration Statement. The Company shall use its commercially reasonable best
efforts to cause the Initial Shelf Registration Statement to be declared
effective under the Securities Act on or prior to the Effectiveness Date, and to
keep the Initial Shelf Registration Statement continuously effective under the
Securities Act until the date which is 36 months from the Issue Date, or such
shorter period ending when (i) all Registrable Securities covered by the Initial
Shelf Registration Statement have been sold in the manner set forth and as
contemplated in the Initial Shelf Registration Statement or (ii) a Subsequent
Shelf Registration Statement covering all of the Registrable Securities has been
declared effective under the Securities Act (such 36 month or shorter period,
the "Effectiveness Period").
     --------------------   

          (b)    Subsequent Shelf Registration Statements. If the Initial Shelf
Registration Statement or any Subsequent Shelf Registration Statement ceases to
be effective for any reason at any time during the Effectiveness Period (other
than because of the sale of all of the securities registered thereunder), the
Company shall use its commercially reasonable best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
the Company shall within 45 days of such cessation of effectiveness amend the
Shelf Registration Statement in a manner reasonably expected to obtain the
withdrawal of the order suspending the effectiveness thereof, or file an
additional "shelf" Registration Statement pursuant to Rule 415 covering all of
the Registrable Securities (a "Subsequent Shelf Registration Statement"). If a
                               ---------------------------------------        
Subsequent Shelf Registration Statement is filed, the Company shall use its
commercially reasonable best efforts to cause the Subsequent Shelf Registration
Statement to be declared effective as soon as reasonably practicable after such
filing and to keep such Registration Statement continuously effective until the
end of the Effectiveness Period. As used herein the term "Shelf Registration
                                                          ------------------
Statement" means the Initial Shelf Registration Statement and any Subsequent
---------                                                                   
Shelf Registration Statement.

          (c)    Supplements and Amendments. The Company shall promptly
supplement and amend the Shelf Registration Statement if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration Statement, if required by the Securities Act, or if
reasonably requested by the Holders of a majority in aggregate principal amount
of the Registrable Securities covered by such Registration Statement or by any
underwriter of such Registrable Securities.

          (d)    Hold-Back Agreements.

            (i)  Restrictions on Public Sale by Holders of Registrable
     Securities. Each Holder of Registrable Securities whose Registrable
     Securities are covered by a Shelf Registration Statement (which Registrable
     Securities are not being sold in the underwritten offering described below)
     agrees, if
<PAGE>
 
                                      -7-

     requested (pursuant to a timely written notice) by the Company or by the
     managing underwriter or underwriters in an underwritten offering, not to
     effect any public sale or distribution of any securities within the class
     of securities covered by such Shelf Registration Statement or any similar
     class of securities of the Company, including a sale pursuant to Rule 144
     or Rule 144A (except as part of such underwritten offering), during the
     period beginning 10 days prior to, and ending 60 days after, the closing
     date of each underwritten offering made pursuant to each Shelf Registration
     Statement, to the extent timely notified in writing by the Company or by
     the managing underwriter or underwriters; provided, however, that each
     holder of Registrable Securities shall be subject to the hold-back
     restrictions of this Section 3(d)(i) only once during the term of this
     Agreement.

          The foregoing provisions shall not apply to any Holder of Registrable
     Securities if such Holder is prevented by applicable statute or regulation
     from entering into any such agreement; provided, however, that any such
     Holder shall undertake, in its request to participate in any such
     underwritten offering, not to effect any public sale or distribution of the
     class of securities covered by such Shelf Registration Statement (except as
     part of such underwritten offering) during such period unless it has
     provided 45 days' prior written notice of such sale or distribution to the
     Company or the managing underwriter or underwriters, as the case may be.

           (ii)  Restrictions on the Company and Others. The Company agrees (A)
     not to effect any public or private sale or distribution (including,
     without limitation, a sale pursuant to Regulation D under the Securities
     Act) of any securities the same as or similar to those covered by a Shelf
     Registration Statement or any securities convertible into or exchangeable
     or exercisable for such securities, during the 10 days prior to, and during
     the 60-day period beginning on, the commencement of an underwritten public
     distribution of Registrable Securities, where the managing underwriter or
     underwriters so requests pursuant to timely written notice; (B) to include
     in any agreements entered into by the Company on or after the date of this
     Agreement (other than any underwriting agreement relating to a public
     offering registered under the Securities Act) pursuant to which the Company
     issues or agrees to issue securities the same as or similar to the Notes a
     provision substantially identical to Section 3(d)(i); and (C) not to grant
     or agree to grant any "piggy-back registration" or other similar rights to
     any holder of the Company's or any of its subsidiaries' securities issued
     on or after the date of this Agreement with respect to any Registration
     Statement.

          (e)    Limitations, Conditions and Qualifications to Obligations Under
Registration Covenants. The obligations of the Company set forth in this Section
3 are subject to each of the following limitations, conditions and
qualifications:

            (i)  Subject to the next sentence of this paragraph, the Company
     shall be entitled to postpone, for a reasonable period of time, the filing
     or effectiveness of, or suspend the rights of any Holders to make sales
     pursuant to, any Registration Statement otherwise required to be prepared,
     filed and made and kept effective by it hereunder; provided, however, that
     the duration of such postponement or suspension may not extend beyond the
     earlier to occur of (A) the day after the cessation of the circumstances
     described in the next sentence of this paragraph on which such postponement
     or suspension is based or (B) 90 days after the date of the determination
     of the Board of Directors referred to in the next sentence. Such
     postponement or suspension may be effected only if the Board of Directors
     of the Company determines reasonably and in good faith that the filing or
     effectiveness of, or sales pursuant to, such Registration Statement would
     materially impede, delay or interfere with any financing, offer or sale of
     securities, acquisition, corporate reorganization or other significant
     transaction involving the Company or any of its affiliates or require
     disclosure of material information which the Company has a
<PAGE>
 
                                      -8-

     bona fide business purpose for preserving as confidential; provided,
     however, that the Company shall be entitled to such postponement or
     suspension only once during the term of this Agreement. If the Company
     shall so postpone the filing of a Registration Statement it shall, as
     promptly as possible, deliver a certificate signed by the chief executive
     officer of the Company to the Holders as to such determination. The
     exercise by the Company of its rights under this Section 3(e) shall not
     relieve it of its obligation to pay Additional Interest pursuant to Section
     4 if the Registration Statement is not filed by the applicable Filing Date
     or declared effective by the applicable Effectiveness Date or postponed or
     suspended beyond the period specified therein.

4.   ADDITIONAL INTEREST

          (a)    The Company and the Initial Purchasers agree that the Holders
of Notes will suffer damages if the Company fails to fulfill its obligations
under Section 2 or Section 3 hereof (including by virtue of its exercise of its
rights under Section 3(d) 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 either the Exchange Offer Registration Statement or the
     Initial Shelf Registration Statement has not been filed on or prior to the
     Filing Date (unless, with respect to the Exchange Offer Registration
     Statement, a Shelf Event shall have occurred prior to the Filing Date),
     Additional Interest shall accrue on the Notes over and above the stated
     interest in an amount equal to $0.05 per week (or any part thereof), per
     $1,000 of Accreted Value (as of the first day of each such week) of Notes
     for the first 90 days immediately following such date, such Additional
     Interest rate increasing by an additional $0.05 per week (or any part
     thereof) per $1,000 of Accreted Value (as of the first day of each such
     week) of the Notes for each subsequent 90-day period;

           (ii)  if either the Exchange Offer Registration Statement or the
     Initial Shelf Registration Statement is not declared effective by the SEC
     on or prior to the Effectiveness Date (unless, with respect to the Exchange
     Offer Registration Statement, a Shelf Event described in clause (i) of
     Section 2(c) above shall have occurred), Additional Interest shall accrue
     on the Notes included or which should have been included in such
     Registration Statement over and above the stated interest in an amount
     equal to $0.05 per week (or any part thereof) per $1,000 of Accreted Value
     (as of the first day of each such week) of Notes for the first 90 days
     immediately following the day after such date, such Additional Interest
     rate increasing by an additional $0.05 per week (or any part thereof) per
     $1,000 of Accreted Value (as of the first day of each such week) of the
     Notes for each subsequent 90-day period; and

          (iii)  if (A) the Company has not exchanged Exchange Securities for
     all Notes validly tendered and not withdrawn in accordance with the terms
     of the Exchange Offer on or prior to the fifth day after the Expiration
     Date, or (B) the Exchange Offer Registration Statement ceases to be
     effective or the Prospectus which is a part thereof cannot be used as a
     result of a postponement or a suspension pursuant to Section 3(e) lasting
     for a period of more than 45 days at any time prior to the Expiration Date,
     or (C) if applicable, any Shelf Registration Statement has been declared
     effective and such Shelf Registration Statement ceases to be effective or
     the Prospectus which is a part thereof cannot be used as a result of a
     postponement or a suspension pursuant to Section 3(e) lasting for a period
     of more than 45 days at any time during the Effectiveness Period, then
     Additional Interest shall accrue on the Notes (over and above any interest
     otherwise payable on the Notes) in an amount equal to $0.05 per week (or
     any part
<PAGE>
 
                                      -9-

     thereof) per $1,000 of Accreted Value (as of the first day of each
     such week) of the Notes for the first 90 days commencing on (x) the sixth
     day after the Expiration Date, in the case of (A) above, or (y) the day the
     Exchange Offer Registration Statement ceases to be effective or a
     postponement or suspension in the case of (B) above, or (z) the day such
     Shelf Registration Statement ceases to be effective in the case of (C)
     above, such Additional Interest rate increasing by an additional $0.05 per
     week (or any part thereof) per $1,000 of Accreted Value (as of the first
     day of each such week) of the Notes 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 $0.50 per week per $1,000 of Accreted Value (as
of the first day of each such week) of the Notes; provided, further, that (1)
upon the filing of the Exchange Offer Registration Statement or a Shelf
Registration Statement as required hereunder (in the case of clause (i) of this
Section 4(a)), (2) upon the effectiveness of the Exchange Offer Registration
Statement or the Shelf Registration Statement as required hereunder (in the case
of clause (ii) of this Section 4(a)) or (3) upon the exchange of Exchange
Securities for all Notes validly tendered and not withdrawn (in the case of
clause (iii)(A) of this Section 4(a)), or upon the effectiveness of the Exchange
Offer Registration Statement which had ceased to remain effective or the end of
the postponement or suspension period (in the case of clause (iii)(B) of this
Section 4(a)), or upon the effectiveness of the Shelf Registration Statement
which had ceased to remain effective (in the case of clause (iii)(C) of this
Section 4(a)), Additional Interest on the Notes as a result of such clause (or
the relevant subclause thereof), as the case may be, shall cease to accrue (but
any accrued amount shall be payable).

          (b)    The Company shall notify the Trustee within one business day
after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). The Company shall
                                                ----------
pay the Additional Interest due on the Registrable Securities by depositing with
the Trustee, in trust, for the benefit of the Holders thereof, on or before the
applicable semi-annual interest payment date, immediately available funds in
sums sufficient to pay the Additional Interest then due to Holders of
Registrable Securities. Each obligation to pay Additional Interest shall be
deemed to accrue immediately following the occurrence of the applicable Event
Date. Any accrued Additional Interest amount shall be due and payable on each
interest payment date immediately after the applicable Event Date to the record
Holder of Registrable Securities entitled to receive the interest payment to be
made on such date as set forth in the Indenture. The parties hereto agree that
the Additional Interest provided for in this Section 4 constitutes a reasonable
estimate of the damages that may be incurred by Holders of Registrable
Securities by reason of the failure of a Shelf Registration Statement or
Exchange Offer Registration Statement to be filed or declared effective, or a
Shelf Registration Statement to remain effective, as the case may be, in
accordance with this Section 4.

5.   REGISTRATION PROCEDURES

          In connection with the registration of any Registrable Securities
pursuant to Sections 2 or 3 hereof, the Company shall use its commercially
reasonable best efforts to effect such registrations to permit the sale of such
Registrable Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall:

          (a)    prepare and file with the SEC on or before the Filing Date, a
Registration Statement or Registration Statements as prescribed by Section 2 or
3, and to use its commercially reasonable best efforts to cause each such
Registration Statement to become effective and remain effective as provided
herein, provided that, if (1) such filing is pursuant to Section 3, or (2) a
Prospectus contained in an Exchange Offer Registration Statement filed pursuant
to Section 2 is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Securities during the
Applicable Period, before filing any Registra-
<PAGE>
 
                                     -10-

tion Statement or Prospectus or any amendments or supplements thereto, the
Company shall furnish to and afford the Holders of the Registrable Securities
and each such Participating Broker-Dealer, as the case may be, covered by such
Registration Statement, 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 (at least five days prior to such filing); the
Company shall not file any Registration Statement or Prospectus or any
amendments or supplements thereto in respect of which the Holders must be
afforded a reasonable opportunity to review prior to the filing of such
document, if the Holders of a majority in aggregate principal amount of the
Registrable Securities covered by such Registration Statement, or such
Participating Broker-Dealer, as the case may be, their counsel, or the managing
underwriters, if any, shall reasonably object;

          (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, in
the case of a Shelf Registration Statement, or until the later of the Expiration
Date and the Applicable Period (if applicable), in the case of the Exchange
Offer Registration Statement; cause the related Prospectus to be supplemented by
any required Prospectus supplement, and as so supplemented to be filed pursuant
to Rule 424 (or any similar provisions then in force) under the Securities Act;
and comply with the provisions of the Securities Act, the Exchange Act and the
rules and regulations of the SEC promulgated thereunder applicable to it with
respect to the disposition of all securities covered by such Registration
Statement as so amended or in such Prospectus as so supplemented and with
respect to the subsequent resale of any securities being sold by a Participating
Broker-Dealer covered by any such Prospectus;

          (c)    if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period notify the selling Holders of
Registrable Securities, 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 five business days), 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 (including in such notice a
written statement that any Holder may, upon request, obtain, without charge, one
conformed copy of such Registration Statement or post-effective amendment
including financial statements and schedules, documents incorporated or deemed
to be incorporated by reference and exhibits); (ii) of the issuance by the SEC
of any stop order suspending the effectiveness of a Registration Statement or of
any order preventing or suspending the use of any 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 Securities the representations and warranties of the
Company contained in any agreement (including any underwriting agreement)
contemplated by Section 5(n) below cease to be true and correct; (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of a Registration Statement or any
of the Registrable Securities or the Exchange Securities 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 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 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 mate-
<PAGE>
 
                                     -11-

rial fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading provided, however, that such
notification need not specifically identify such event if notification of the
occurrence thereof would in the Company's reasonable judgment, involve the
disclosure of confidential non-public information; and (vi) of the Company's
reasonable determination that a post-effective amendments to the Registration
Statement would be appropriate;

          (d)    if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, use its commercially 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 Securities or the Exchange Securities to be sold by any
Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
order is issued, to use its commercially reasonable best efforts to obtain the
withdrawal of any such order at the earliest possible moment;

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

          (f)    if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, furnish to each selling Holder of
Registrable Securities and to each such Participating Broker-Dealer who so
requests and upon request to their respective counsel and each managing
underwriter, if any, without charge, one conformed copy of the Registration
Statement or Statements and each post-effective amendment thereto, including
financial statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference and all exhibits;

          (g)    if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, deliver to each selling Holder of
Registrable Securities, or each such Participating Broker-Dealer, as the case
may be, their counsel, and the underwriters, if any, without charge, 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 Company hereby consents to
the use of such Prospectus and each amendment or supplement thereto by each of
the selling holders of Registrable Securities 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 Securities
covered by or the sale by Participating Broker-Dealers of the Exchange
Securities pursuant to such Prospectus and any amendment or supplement thereto
provided such use complies with all applicable laws and regulations;
<PAGE>
 
                                     -12-

          (h)    prior to any public offering of Registrable Securities or any
delivery of a Prospectus contained in the Exchange Offer Registration Statement
by any Participating Broker-Dealer who seeks to sell Exchange Securities during
the Applicable Period, use its commercially reasonable best efforts to register
or qualify, and to cooperate with the selling Holders of Registrable Securities
or each such Participating Broker-Dealer, as the case may be, the underwriters,
if any, and their respective counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities 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 underwriters reasonably request in
writing, provided that where Exchange Securities held by Participating Broker-
Dealers or Registrable Securities are offered other than through an underwritten
offering, the Company shall cause its counsel to (i) perform Blue Sky
investigations and file registrations and qualifications required to be filed
pursuant to this Section 5(h); (ii) use its commercially reasonable best efforts
to keep each such registration or qualification (or exemption therefrom)
effective during the period such Registration Statement is required to be kept
effective; and (iii) do any and all other acts or things necessary or advisable
to enable the disposition in such jurisdictions of the Exchange Securities held
by Participating Broker-Dealers or the Registrable Securities covered by the
applicable Registration Statement, provided further that the Company shall not
in any case 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, (C) subject itself to taxation in excess of a nominal
dollar amount in any such jurisdiction or (D) conform its capitalization or the
composition of its assets to the securities or blue sky laws of any such
jurisdiction;

          (i)    if a Shelf Registration Statement is filed pursuant to Section
3, cooperate with the selling Holders of Registrable Securities and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing Registrable Securities 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
Securities to be in such denominations and registered in such names as the
managing underwriter or underwriters, if any, or Holders may reasonably request;

          (j)    use its commercially reasonable best efforts to cause the
Registrable Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to enable the seller or sellers thereof or the underwriters, if any,
to consummate the disposition of such Registrable Securities, except as may be
required solely as a consequence of the nature of such selling Holder's
business, in which case the Company will cooperate in all reasonable respects
with the filing of such Registration Statement and the granting of such
approvals;

          (k)    if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, upon the occurrence of any event
contemplated by paragraph 5(c)(v) or 5(c)(vi) above, as promptly as practicable
prepare and (subject to Section 5(a) above) file with the SEC, solely at the
expense of the Company, 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 Securities being sold thereunder or to the purchasers of the
Exchange Securities 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 the light of the circumstances
under which they were made, not misleading;

Registrable Securities covered by a Registration Statement or the Exchange
Securities, as the case may be, to be rated with the appropriate rating
agencies, if so requested by the Holders of a majority in aggregate principal
amount of Registrable Securities covered by such Registration Statement or the
Exchange Securities, as the case may be, or the managing underwriters, if any;

          (m)    prior to the effective date of the first Registration Statement
relating to the Registrable Securities, (i) provide the Trustee with printed

expedite or facilitate the registration or the disposition of such Registrable
Securities, and in such connection if reasonably requested, (i) make such
representations and warranties to the underwriters, with respect to the business

its subsidiaries for which financial statements and financial data are, or are
required to be, included in the Registration Statement), addressed to each of
the underwriters, such letters to be in customary form and covering matters of

underwritten offerings and such other matters as reasonably requested by
underwriters; and (iv) if an underwriting agreement is entered into, the same

corporate documents and properties of the Company and its subsidiaries

                                     -14-

(collectively, the "Records") as shall be necessary to enable them to exercise
                    -------                                                   
any applicable due diligence responsibilities, and cause the officers, directors
and employees of the Company and its subsidiaries to supply all information in
each case requested by any such Inspector in connection with such Registration
Statement; however, records which the Company determines, in good faith, to be
confidential and any Records which the Company notifies the Inspectors are
confidential shall not be disclosed by the Inspectors unless (i) the disclosure
of such Records is necessary to avoid or correct a misstatement or omission in
such Registration Statement; (ii) the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction;
(iii) the information in such Records has been made generally available to the
public; or (iv) release thereof is necessary or advisable in connection with any
action, suit or proceeding involving any Holder or other Inspector;

in connection therewith, cooperate with the trustee under any such indenture and
the holders of the Registrable Securities, 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 commercially 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;

          (q)    comply with all applicable rules and regulations of the SEC to
the extent and so long as they are applicable to the Exchange Offer Registration
Statement or the Shelf Registration Statement and make generally available to
their securityholders earning statements satisfying the provisions of Section
11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the Securities Act) no later than 45 days after the end of any
12-month period (or 90 days after the end of any 12-month period if such period
is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to underwriters in a firm commitment or
commercially reasonable 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;

          (r)    upon consummation of an Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Company in customary form, relating to the
Exchange Securities or the Private Exchange Securities, as the case may be,
addressed to the Trustee for the benefit of all Holders of Registrable
Securities participating in the Exchange Offer or the Private Exchange, as the
case may be, and which includes an opinion that (i) the Company has duly
authorized, executed and delivered the Exchange Securities and Private Exchange
Securities and the related indenture; and (ii) each of the Exchange Securities
or the Private Exchange Securities, as the case may be, and related indenture
constitute legal, valid and binding obligations of the Company, enforceable
against the Company in accordance with their respective terms (with customary
exceptions);

          (s)    if an Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Securities by Holders to the
Company (or to such other Person as directed by the Company) in exchange for the
Exchange Securities or the Private Exchange Securities, as the case may be,
mark, or caused to be marked, on such Registrable Securities that such
Registrable Securities are being cancelled in exchange for the Exchange
Securities or the Private Exchange Securities, as the case may be; in no event
shall such Registrable Securities be marked as paid or otherwise satisfied;
<PAGE>
 
                                     -15-

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

          (u)    use its commercially reasonable best efforts to take all other
steps necessary to effect the registration of the Registrable Securities covered
by a Registration Statement contemplated hereby.

          The Company may require each seller of Registrable Securities or
Participating Broker-Dealer as to which any registration is being effected to
furnish to the Company such information regarding such seller or Participating
Broker-Dealer and the distribution of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
as the Company may, from time to time, reasonably request. The Company may
exclude from such registration the Registrable Securities of any seller or
Participating Broker-Dealer who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

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

6.   REGISTRATION EXPENSES

          (a)    All fees and expenses incident to the performance of or

brokerage commissions, dealers' selling concessions, transfer taxes or any other
selling expenses (other than those expressly enumerated in clauses (i) through
(xiii) above) incurred in connection with the underwriting, offering or sale of
Registrable Securities or Exchange Securities by or on behalf of any Person.

          (b)    In connection with any Shelf Registration Statement hereunder,
the Company shall reimburse the Holders of the Registrable Securities being

more than one counsel (in addition to appropriate local counsel) chosen by the
Holders of a majority in aggregate principal amount of the Registrable
Securities to be included in such Registration Statement and other reasonable
out-of-pocket expenses of the Holders of Registrable Securities incurred in
connection with the registration of the Registrable Securities.

7.   INDEMNIFICATION

          The Company agrees to indemnify and hold harmless each Holder of
Registrable Securities and each Participating Broker-Dealer selling Exchange
Securities during the Applicable Period, the officers and directors of each such
person, and each person, if any, who controls any such person within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act
(each, a "Participant"), from and against any and all losses, claims, damages
          -----------                                                        
and liabilities (including, without limitation, the reasonable legal fees and
other expenses actually incurred in connection with any suit, action or
proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement (or
any amendment thereto) or Prospectus (as amended or supplemented if the Company
shall have furnished any amendments or supplements thereto) or any preliminary
prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the 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
such Participant furnished to the Company in writing by such Participant (or, if
such Participant is not a Holder or a Participating Broker-Dealer, furnished in
writing by the Holder or Participating Broker-Dealer in respect of which such
person is a Participant relating to such Participant) expressly for use therein;
provided that (i) the foregoing indemnity with respect to any preliminary
prospectus shall not inure to the benefit of any Participant (or to the benefit
of any offer or director of, or of any person controlling, such Participant)
from whom the person asserting any such losses, claims, damages or liabilities
purchased Registrable Securities to the extent that such untrue statement or
omission or alleged untrue statement or omission made in such preliminary
prospectus is eliminated or remedied in the related Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) and a copy of the related Prospectus (as so amended or supplemented)
shall not have been 
<PAGE>
 
                                     -17-

furnished to such person at or prior to the sale of such Registrable Securities
or Exchange Securities, as the case may be, to such person and (ii) the
foregoing indemnity with respect to any Prospectus shall not inure to the
benefit of a Holder of Registrable Securities or Participating Broker-Dealer to
the extent that such Holder or Participating Broker-Dealer uses such Prospectus
five business days after such time as the Company shall have advised such Holder
or Participating Broker-Dealer in writing of the happening of any event which
makes any statement of a material fact made in such Prospectus untrue or which
requires the making of any additions to or changes in such Prospectus in order
that it will not contain an untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they are made,
not misleading.

          Each Participant will be required to agree, severally and not jointly,
to indemnify and hold harmless each of the Company, its directors, its officers
who sign the Registration Statement and each person who controls the Company
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
each 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 Securities giving rise to such
obligations.

          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 person against whom such indemnity may be sought (the "Indemnifying
                                                                  ------------
Person") in writing, and the Indemnifying Person, 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 Person may designate in such proceeding and shall pay the
reasonable fees and expenses incurred by such counsel related to such
proceeding, provided, that the failure to so notify the Indemnifying Person
shall not relieve it of any obligation or liability which it may have hereunder
or otherwise (unless and only to the extent that such failure actually
prejudices the Indemnifying Person).  In any such proceeding, any Indemnified
Person shall have the right to retain its own counsel, but, other than in
circumstances involving a conflict among  Indemnified Persons, the fees and
expenses of such counsel shall be at the expense of such Indemnified Person
unless (i) the Indemnifying Person and the Indemnified Person shall have agreed
to the contrary; (ii) the Indemnifying Person has failed within a reasonable
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 the Indemnifying Person and the Indemnified Person and
representation of both parties by the same counsel would be inappropriate due to
an actual or potential conflict of interest.  It is understood that, other than
in circumstances involving a conflict among Indemnified Persons, the
Indemnifying Person shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for the Participants shall be designated in
writing by Participants who sold a majority in interest of Registrable
Securities sold by all such Participants and any such separate firm for the
Company, its directors, its officers and such control persons of the Company
shall be designated in writing by the Company. The Indemnifying Person shall not
be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified
Person shall have requested an Indemnifying Person to reimburse the Indemnified
Person for reasonable fees and expenses incurred by counsel as contemplated by
the third sentence of this paragraph, the Indemnifying Person agrees that 
<PAGE>
 
                                     -18-

it shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 60 days after
receipt by such Indemnifying Person of the aforesaid request and (ii) such
Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement; provided,
however, that the Indemnifying Person shall not be liable for any settlement
effected without its consent pursuant to this sentence if the Indemnifying Party
is contesting, in good faith, the request for reimbursement. No Indemnifying
Person shall, without the prior written consent of the Indemnified Person,
effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party, unless such
settlement includes an unconditional written release of such Indemnified Person
in form and substance satisfactory to the Indemnified Persons from all liability
on claims that are the subject matter of such proceeding.

          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 Person 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 initial
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 benefits received by the
Company on the one hand and the Participants on the other shall be deemed to be
in the same proportion as the total proceeds from the initial offering (net of
discounts and commissions but before deducting expenses) of the Notes received
by the Company bears to the total proceeds received by such Participant from the
sale of Registrable Securities. 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 Company, 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.

          The parties shall 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 and liabilities 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 Securities
exceeds the amount of any damages that such Participant 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.
<PAGE>
 
                                     -19-

          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.   RULE 144 AND RULE 144A

          The Company covenants 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 and, if at any time
the Company is not required to file such reports, it will, upon the request of
any Holder of Registrable Securities, make publicly available other information
so long as necessary to permit sales pursuant to Rule 144 and Rule 144A under
the Securities Act. The Company further covenants that it will take such further
action as any Holder of Registrable Securities may reasonably request, to the
extent required from time to time to enable such Holder to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 and Rule 144A under the Securities Act.

9.   UNDERWRITTEN REGISTRATIONS

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

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) 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 (however the terms applicable to each Holder shall be identical in
all respects) and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements applicable to all Holders.

10.  MISCELLANEOUS

          (a)    Remedies.  In the event of a breach by the Company of any of
its obligations under this Agreement, each Holder of Registrable Securities, in
addition to being entitled to exercise all rights provided herein, in the
Indenture or, in the case of the Initial Purchasers, in the Purchase Agreement
or granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Agreement. The Company agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by it of any of the provisions of this Agreement and hereby further
agrees that, in the event of any action for specific performance in respect of
such breach, it shall waive the defense that a remedy at law would be adequate.

          (b)    No Inconsistent Agreements.  The Company has not, as of the
date hereof, entered into and 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 Securities in this
Agreement or otherwise conflicts with the provisions hereof. The Company has not
entered into and will not enter into any agreement with respect to any of its
securities which will grant to any Person "piggy-back" rights with respect to a
Registration Statement.

          (c)    Adjustments Affecting Registrable Securities.  The Company
shall not, directly or indirectly, take any action with respect to the
Registrable Securities as a class that would adversely affect the abil-
<PAGE>
 
                                     -20-

ity of the Holders of Registrable Securities to include such Registrable
Securities in a registration undertaken pursuant to this Agreement.

          (d)    Guarantors.  So long as any Registrable Securities remain
outstanding, the Company shall cause each of its subsidiaries that becomes a
guarantor of the Notes under the Indenture to execute and deliver a counterpart
to this Agreement which subjects such subsidiary to the provisions of this
agreement as a guarantor (all such subsidiaries, the "Guarantors").  Each of the
                                                      ----------                
Guarantors agrees to join the Company in all of its undertakings hereunder to
effect the Exchange Offer for the Exchange Securities (which will be guaranteed
by each of the Guarantors with terms identical to such Guarantors' guaranty of
the Notes) and the filing of any Shelf Registration Statement required hereunder
(including, without limitation, the undertakings in Section 5 hereof).

          (e)    Amendments and Waivers.  Except as provided in paragraph (d)
above, 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 (A) the
Holders of not less than a majority in aggregate principal amount of the then
outstanding Registrable Securities and (B) in circumstances that would adversely
affect the Participating Broker-Dealers, the Participating Broker-Dealers
holding not less than a majority in aggregate principal amount of the Exchange
Securities held by all Participating Broker-Dealers; provided, however, that
Section 7 and this Section 10(d) 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 Securities or Exchange Securities, 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 Securities 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 Securities may be given by Holders of at least a majority in
aggregate principal amount of the Registrable Securities being sold by such
Holders pursuant to such Registration Statement.

          (f)    Notices.  All notices and other communications (including
without limitation any notices or other communications to the Trustee) provided
for or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, next-day air courier or telecopier:

            (i)  if to a Holder of Registrable Securities, at the most current
     address given by the Trustee to the Company; and

           (ii)  if to the Company, at TCI Satellite Entertainment, Inc., 8085
     South Chester #300, Englewood, CO 80112, Attention: Chief Financial

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; one business day
after being timely delivered to a next-day air courier; and when receipt is
acknowledged by the addressee, if telecopied.

          Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the trustee under the
Indenture at the address specified in such Indenture.

          (g)    Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent Holders of Registrable Securities.

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

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

          (j)    GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

          (k)    Severability.  If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially 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 restrictions without
including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

          (l)    Entire Agreement.  This Agreement, together with the Purchase
Agreement, is intended by the parties as a final expression of their agreement,
and is intended to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained
herein and therein.

          (m)    Securities Held by the Company or Its Affiliates.  Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its affiliates (as such term is defined in Rule 405 under the Securities Act)
shall not be deemed to be not outstanding for purposes of determining whether
such consent or approval was given by the Holders of such required percentage.
