SECTION 2.  HOLDERS

          A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "Holder") whenever such Person owns Transfer Restricted Securities.
          ------

SECTION 3.  REGISTERED EXCHANGE OFFER

          (a)  Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company and the Guarantors shall (i) cause the Exchange
Offer Registration Statement to be filed with the Commission as soon as
practicable after the Closing Date, but in no event later than 90 days after the
Closing Date (such 90th day being the "Filing Deadline"), (ii) use its best
                                       ---------------
efforts to cause such Exchange Offer Registration Statement to become effective
at the earliest possible time, but in no event later than 180 days after the
Closing Date (such 180th day being the "Effectiveness Deadline"), (iii) in
                                        ----------------------
connection with the foregoing, (A) file all pre-effective amendments to such
Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, (B) file, if applicable, a post-effective amendment to such
Exchange Offer Registration Statement pursuant to Rule 430A under the Act and
(C) cause all necessary filings, if any, in connection with the registration and
qualification of the Series B Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and Consummate the Exchange Offer.  The Exchange Offer shall be on the
appropriate form permitting (i) registration of the Series B Notes to be offered
in exchange for the Series A Notes that are Transfer Restricted Securities and
(ii) resales of Series B Notes by Broker-Dealers that tendered into the Exchange
Offer Series A Notes that such Broker-Dealer acquired for its own account as a
result of market making activities or other trading activities (other than
Series A Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

          (b)  The Company and the Guarantors shall use their respective best
efforts to cause the Exchange Offer Registration Statement to be effective
continuously, and shall keep the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
laws to Consummate the Exchange Offer; provided, however, that in no event shall
such period be less than 20 Business Days.  The Company and the Guarantors shall
cause the Exchange Offer to comply with all applicable federal and state
securities laws.  No securities other than the Series B Notes shall be included
in the Exchange Offer Registration Statement.  The Company and the Guarantors
shall use their respective

                                       4
<PAGE>

best efforts to cause the Exchange Offer to be Consummated on the earliest
practicable date after the Exchange Offer Registration Statement has become
effective, but in no event later than 30 business days thereafter (such 30/th/
day being the "Consummation Deadline").
               ---------------------

          (c)  The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer.  Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement.  See the Shearman & Sterling no-action letter (available
July 2, 1993).

          Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement.  To the extent necessary to ensure that the prospectus
contained in the Exchange Offer Registration Statement is available for sales of
Series B Notes by Broker-Dealers, the Company and the Guarantors agree to use
their respective best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Section 6(a) and (c) hereof and in conformity with
the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto.  The Company and the Guarantors shall provide
sufficient copies of the latest version of such Prospectus to such Broker-
Dealers, promptly upon request, and in no event later than one day after such
request, at any time during such period.

                                       5

SECTION 4.  SHELF REGISTRATION

          (a)  Shelf Registration.  If (i) the Exchange Offer is not permitted
               ------------------
by applicable law (after the Company and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the Consummation Deadline that (A) such Holder was prohibited by law or
Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the Series B Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds Series A
Notes acquired directly from the Company or any of its Affiliates, then the
Company and the Guarantors shall:

          (x)  cause to be filed, on or prior to 30 days after the earlier of
(i) the date on which the Company determines that the Exchange Offer
Registration Statement cannot be filed as a result of clause (a)(i) above and
(ii) the date on which the Company receives the notice specified in clause
(a)(ii) above, (such earlier date, the "Filing Deadline"), a shelf registration
                                        ---------------
statement pursuant to Rule 415 under the Act (which may be an amendment to the
Exchange Offer Registration Statement (the "Shelf Registration Statement")),
                                            ----------------------------
relating to all Transfer Restricted Securities, and

          (y)  shall use their respective best efforts to cause such Shelf
Registration Statement to become effective on or prior to 60 days after the
Filing Deadline for the Shelf Registration Statement (such 60th day the
"Effectiveness Deadline").
 ----------------------

          If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Company shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

          To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Company and the Guarantors shall use their respective best efforts
to keep any Shelf Registration Statement required by this Section 4(a)
continuously effective, supplemented, amended and

                                       6
<PAGE>

current as required by and subject to the provisions of Sections 6(b) and (c)
hereof and in conformity with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period of at least two years (as extended pursuant to Section
6(c)(i)) following the Closing Date, or such shorter period as will terminate on
the earlier of the date on which (1) all Transfer Restricted Securities covered
by such Shelf Registration Statement have been sold pursuant thereto or (2)
there cease to be outstanding any Transfer Restricted Securities.

          (b)  Provision by Holders of Certain Information in Connection with
               --------------------------------------------------------------
the Shelf Registration Statement.  No Holder of Transfer Restricted Securities
--------------------------------
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information.  Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

SECTION 5.  LIQUIDATED DAMAGES

          If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within two days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective within five days of filing such post-
effective amendment to such Registration Statement (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Company and the
                                --------------------
Guarantors hereby jointly and severally agree to pay to each Holder of Transfer
Restricted Securities affected thereby liquidated damages in an amount equal to
$.05 per week per $1,000 in principal amount of Transfer Restricted Securities
held by such Holder for each week or portion thereof that the Registration
Default continues for the first 90-day period immediately following the
occurrence of

                                       7
<PAGE>

such Registration Default. The amount of the liquidated damages shall increase
by an additional $.05 per week per $1,000 in principal amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $.25 per week per $1,000 in principal amount of Transfer Restricted
Securities; provided that the Company and the Guarantors shall in no event be
required to pay liquidated damages for more than one Registration Default at any
given time. Notwithstanding anything to the contrary set forth herein, (1) upon
filing of the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement), in the case of (i) above, (2) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon
the filing of a post-effective amendment to the Registration Statement or an
additional Registration Statement that causes the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement) to again be
declared effective or made usable in the case of (iv) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

          All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Notes.  Notwithstanding the fact that any securities for which liquidated
damages are due cease to be Transfer Restricted Securities, all obligations of
the Company and the Guarantors to pay liquidated damages with respect to
securities shall survive until such time as such obligations with respect to
such securities shall have been satisfied in full.  Following the cure of all
Registration Defaults relating to any Transfer Restricted Securities, the
accrual of Liquidated Damages with respect to such Transfer Restricted
Securities will cease.  Each obligation to pay Liquidated Damages shall be
deemed to commence accruing on the date of the applicable Registration Default
and to cease accruing when all Registration Defaults have been cured.  In no
event shall the Company pay Liquidated Damages in excess of the applicable
maximum weekly amount set forth above regardless of whether one or multiple
Registration Defaults exist.

SECTION 6.  REGISTRATION PROCEDURES

          (a)  Exchange Offer Registration Statement.  In connection with the
               -------------------------------------
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Series B Notes by
Broker-Dealers

                                       8
<PAGE>

that tendered in the Exchange Offer Series A Notes that such Broker-Dealer
acquired for its own account as a result of its market making activities or
other trading activities (other than Series A Notes acquired directly from the
Company or any of its Affiliates) being sold in accordance with the intended
method or methods of distribution thereof, and (z) comply with all of the
following provisions:

               (i)   If, following the date hereof there has been announced a
change in Commission policy with respect to exchange offers such as the Exchange
Offer, that in the reasonable opinion of counsel to the Company raises a
substantial question as to whether the Exchange Offer is permitted by applicable
federal law, the Company and the Guarantors hereby agree to seek a no-action
letter or other favorable decision from the Commission allowing the Company and
the Guarantors to Consummate an Exchange Offer for such Transfer Restricted
Securities. The Company and the Guarantors hereby agree to pursue the issuance
of such a decision to the Commission staff level. In connection with the
foregoing, the Company and the Guarantors hereby agree to take all such other
actions as may be requested by the Commission or otherwise required in
connection with the issuance of such decision, including without limitation (A)
participating in telephonic conferences with the Commission, (B) delivering to
the Commission staff an analysis prepared by counsel to the Company setting
forth the legal bases, if any, upon which such counsel has concluded that such
an Exchange Offer should be permitted and (C) diligently pursuing a resolution
(which need not be favorable) by the Commission staff.

               (ii)  As a condition to its participation in the Exchange Offer,
each Holder of Transfer Restricted Securities (including, without limitation,
any Holder who is a Broker Dealer) shall furnish, upon the request of the
Company, prior to the Consummation of the Exchange Offer, a written
representation to the Company and the Guarantors (which may be contained in the
letter of transmittal contemplated by the Exchange Offer Registration Statement)
to the effect that (A) it is not an Affiliate of the Company, (B) it is not
engaged in, and does not intend to engage in, and has no arrangement or
understanding with any person to participate in, a distribution of the Series B
Notes to be issued in the Exchange Offer and (C) it is acquiring the Series B
Notes in its ordinary course of business. As a condition to its participation in
the Exchange Offer each Holder using the Exchange Offer to participate in a
distribution of the Series B Notes shall acknowledge and agree that, if the
resales are of Series B Notes obtained by such Holder in exchange for Series A
Notes acquired directly from the Company or an Affiliate thereof, it (1) could
not, under Commission policy as in effect on the date of this Agreement, rely on
the position of the Commission enunciated in Morgan Stanley and Co., Inc.
                                             ----------------------------

obtained pursuant to clause (i) above), and (2) must comply with the
registration and prospectus delivery requirements of the Act in connection with
a secondary resale transaction and that such a secondary resale transaction must
be covered by an effective registration statement containing the selling
security holder information required by Item 507 or 508, as applicable, of
Regulation S-K.

               (iii) Prior to effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors shall provide a supplemental letter to
the Commission (A) stating that the Company and the Guarantors are registering
the Exchange Offer in reliance on the position of the Commission enunciated in
Exxon Capital Holdings Corporation (available May 13, 1988), Morgan Stanley and
----------------------------------                           ------------------

---------
Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action letter
-------------------
obtained pursuant to clause (i) above, (B) including a representation that
neither the Company nor any Guarantor has entered into any arrangement or
understanding with any Person to distribute the Series B Notes to be received in
the Exchange Offer and that, to the best of the Company's and each Guarantor's
information and belief, each Holder participating in the Exchange Offer is
acquiring the Series B Notes in its ordinary course of business and has no
arrangement or understanding with any Person to participate in the distribution
of the Series B Notes received in the Exchange Offer and (C) any other
undertaking or representation required by the Commission as set forth in any no-
action letter obtained pursuant to clause (i) above, if applicable.

          (b)  Shelf Registration Statement.   In connection with the Shelf
               ----------------------------
Registration Statement, the Company and the Guarantors shall:

          (i)  comply with all the provisions of Section 6(c) below and use
their respective best efforts to effect such registration to permit the sale of
the Transfer Restricted Securities being sold in accordance with the intended
method or methods of distribution thereof (as indicated in the information
furnished to the Company pursuant to Section 4(b) hereof), and pursuant thereto
the Company and the Guarantors will prepare and file with the Commission a
Registration Statement relating to the registration on any appropriate form
under the Act, which form shall be available for the sale of the Transfer
Restricted Securities in accordance with the intended method or methods of
distribution thereof within the time periods and otherwise in accordance with
the provisions hereof.

          (ii) issue, upon the request of any Holder or purchaser of Series A
Notes covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Notes having an aggregate principal amount equal to the
aggregate principal

                                       10
<PAGE>

     amount of Series A Notes sold pursuant to the Shelf Registration Statement
     and surrendered to the Company for cancellation; the Company shall register
     Series B Notes on the Shelf Registration Statement for this purpose and
     issue the Series B Notes to the purchaser(s) of securities subject to the
     Shelf Registration Statement in the names as such purchaser(s) shall
     designate.

          (c)  General Provisions. In connection with any Registration
               ------------------
     Statement and any related Prospectus required by this Agreement, the
     Company and the Guarantors shall:

               (i)    use their respective best efforts to keep such
     Registration Statement continuously effective and provide all requisite
     financial statements for the period specified in Section 3 or 4 of this
     Agreement, as applicable. Upon the occurrence of any event that would cause
     any such Registration Statement or the Prospectus contained therein (A) to
     contain an untrue statement of material fact or omit to state any material
     fact necessary to make the statements therein not misleading or (B) not to
     be effective and usable for resale of Transfer Restricted Securities during
     the period required by this Agreement, the Company and the Guarantors shall
     file promptly an appropriate amendment to such Registration Statement
     curing such defect, and, if Commission review is required, use their
     respective best efforts to cause such amendment to be declared effective as
     soon as practicable.

               (ii)   prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such Registration Statement effective for the
     applicable period set forth in Section 3 or 4 hereof, as the case may be;
     cause the Prospectus to be supplemented by any required Prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
     under the Act in a timely manner; and comply with the provisions of the Act
     with respect to the disposition of all securities covered by such
     Registration Statement during the applicable period in accordance with the
     intended method or methods of distribution by the sellers thereof set forth
     in such Registration Statement or supplement to the Prospectus;

               (iii)  advise each Holder promptly and, if requested by such
     Holder, confirm such advice in writing, (A) when the Prospectus or any
     Prospectus supplement or post-effective amendment has been filed, and, with
     respect to any applicable Registration Statement or any post-effective
     amendment thereto, when the same has become effective, (B) of any request
     by the Commission for amendments to the Registration Statement or
     amendments or supplements to the Prospectus or for additional information
     relating thereto, (C) of the issuance by the Commission of any

                                       11
<PAGE>

     stop order suspending the effectiveness of the Registration Statement under
     the Act or of the suspension by any state securities commission of the
     qualification of the Transfer Restricted Securities for offering or sale in
     any jurisdiction, or the initiation of any proceeding for any of the
     preceding purposes, (D) of the existence of any fact or the happening of
     any event that makes any statement of a material fact made in the
     Registration Statement, the Prospectus, any amendment or supplement thereto
     or any document incorporated by reference therein untrue, or that requires
     the making of any additions to or changes in the Registration Statement in
     order to make the statements therein not misleading, or that requires the
     making of any additions to or changes in the Prospectus in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. If at any time the Commission shall issue any
     stop order suspending the effectiveness of the Registration Statement, or
     any state securities commission or other regulatory authority shall issue
     an order suspending the qualification or exemption from qualification of
     the Transfer Restricted Securities under state securities or Blue Sky laws,
     the Company and the Guarantors shall use their respective best efforts to
     obtain the withdrawal or lifting of such order at the earliest possible
     time;

                    (iv)   subject to Section 6(c)(i), if any fact or event
     contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
     prepare a supplement or post-effective amendment to the Registration
     Statement or related Prospectus or any document incorporated therein by
     reference or file any other required document so that, as thereafter
     delivered to the purchasers of Transfer Restricted Securities, the
     Prospectus will not contain an untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

                    (v)    furnish to each Holder in connection with such
     exchange or sale, if any, before filing with the Commission, copies of any
     Registration Statement or any Prospectus included therein or any amendments
     or supplements to any such Registration Statement or Prospectus (including
     all documents incorporated by reference after the initial filing of such
     Registration Statement), which documents will be subject to the review and
     comment of such Holders in connection with such sale, if any, for a period
     of at least five Business Days prior to the initial filing of a
     Registration Statement and at least three Business Days prior to the filing
     of any amendment or supplement thereto, and the Company will not file any
     such Registration Statement or Prospectus or any amendment or supplement to
     any such Registration Statement or Prospectus (including all such documents
     incorporated by reference) to which such Holders shall reasonably object
     within five Business Days or three Business Days, as applicable, after the
     receipt thereof. A Holder shall be deemed to have reasonably objected to
     such filing if such Registration Statement,

                                       12
<PAGE>

     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading or
     fails to comply with the applicable requirements of the Act;

                    (vi)   promptly prior to the filing of any document that is
     to be incorporated by reference into a Registration Statement or
     Prospectus, provide copies of such document to each Holder in connection
     with such exchange or sale, if any, make the Company's and the Guarantors'
     representatives available for discussion of such document and other
     customary due diligence matters, and include such information in such
     document prior to the filing thereof as such Holders may reasonably
     request;

                    (vii)  subject to reasonable confidentiality procedures,
     make available, at reasonable times, for inspection by each Holder and any
     attorney or accountant retained by such Holders, all financial and other
     records, pertinent corporate documents of the Company and the Guarantors
     and cause the Company's and the Guarantors' officers, directors and
     employees to supply all information reasonably requested by any such
     Holder, attorney or accountant in connection with such Registration
     Statement or any post-effective amendment thereto subsequent to the filing
     thereof and prior to its effectiveness;

                    (viii) if requested by any Holders in connection with such
     exchange or sale, promptly include in any Registration Statement or
     Prospectus, pursuant to a supplement or post-effective amendment if
     necessary, such information as such Holders may reasonably request to have
     included therein, including, without limitation, information relating to
     the "Plan of Distribution" of the Transfer Restricted Securities, and make
     all required filings of such Prospectus supplement or post-effective
     amendment as soon as practicable after the Company is notified of the
     matters to be included in such Prospectus supplement or post-effective
     amendment;

                    (ix)   furnish to each Holder in connection with such
     exchange or sale, without charge, at least one copy of the Registration
     Statement, as first filed with the Commission, and of each amendment
     thereto, including all documents incorporated by reference therein and all
     exhibits (including exhibits incorporated therein by reference);

                    (x)    deliver to each Holder, without charge, as many
     copies of the Prospectus (including each preliminary prospectus) and any
     amendment or supplement thereto as such Persons reasonably may request; the
     Company and the Guarantors hereby consent to the use (in accordance with
     law) of the Prospectus and

                                       13
<PAGE>

     any amendment or supplement thereto by each selling Holder in connection
     with the offering and the sale of the Transfer Restricted Securities
     covered by the Prospectus or any amendment or supplement thereto;

                    (xi)   upon the request of any Holder, enter into such
     agreements (including underwriting agreements) and make such
     representations and warranties and take all such other actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any applicable Registration
     Statement contemplated by this Agreement as may be reasonably requested by
     any Holder in connection with any sale or resale pursuant to any applicable
     Registration Statement. In such connection the Company and the Guarantors
     shall:

                    (A)    upon request of any Holder, furnish (or in the case
          of paragraphs (2) and (3), use its best efforts to cause to be
          furnished) to each Holder, upon Consummation of the Exchange Offer or
          upon the effectiveness of the Shelf Registration Statement, as the
          case may be:

                              (1) a certificate, dated such date, signed on
          behalf of the Company and each Guarantor by (x) the Chief Executive
          Officer, the President or any Vice President and (y) a principal
          financial or accounting officer of the Company and such Guarantor,
          confirming, as of the date thereof, the matters set forth in Sections
          6(y), 9(a) and 9(b) of the Purchase Agreement and such other similar
          matters as such Holders may reasonably request;

                              (2) an opinion, dated the date of Consummation of
          the Exchange Offer or the date of effectiveness of the Shelf
          Registration Statement, as the case may be, of counsel for the Company
          and the Guarantors covering matters similar to those set forth in
          paragraph (e) of Section 9 of the Purchase Agreement and such other
          matters as such Holder may reasonably request, and in any event
          including a statement to the effect that such counsel has participated
          in conferences with officers and other representatives of the Company
          and the Guarantors and representatives of the independent public
          accountants for the Company and the Guarantors and has considered the
          matters required to be stated therein and the statements contained
          therein, although such counsel has not independently verified the
          accuracy, completeness or fairness of such statements; and that such
          counsel advises that, on the basis of the foregoing, no facts came to
          such counsel's attention that caused such counsel to believe that the

                                       14
<PAGE>

          applicable Registration Statement, at the time such Registration
          Statement or any post-effective amendment thereto became effective
          and, in the case of the Exchange Offer Registration Statement, as of
          the date of Consummation of the Exchange Offer, contained an untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, or that the Prospectus contained in such
          Registration Statement as of its date and, in the case of the opinion
          dated the date of Consummation of the Exchange Offer, as of the date
          of Consummation, contained an untrue statement of a material fact or
          omitted 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. Without limiting the foregoing, such
          counsel may state further that such counsel assumes no responsibility
          for, and has not independently verified, the accuracy, completeness or
          fairness of the financial statements, notes and schedules and other
          financial data included in any Registration Statement contemplated by
          this Agreement or the related Prospectus; and

                              (3) a customary comfort letter, dated the date of
          Consummation of the Exchange Offer, or as of the date of effectiveness
          of the Shelf Registration Statement, as the case may be, from the
          Company's independent accountants, in the customary form and covering
          matters of the type customarily covered in comfort letters to
          underwriters in connection with underwritten offerings, and affirming
          the matters set forth in the comfort letters delivered pursuant to
          Section 9(g) of the Purchase Agreement; and

                       (B) deliver such other documents and certificates as may
          be reasonably requested by the selling Holders to evidence compliance
          with the matters covered in clause (A) above and with any customary
          conditions contained in any agreement entered into by the Company and
          the Guarantors pursuant to this clause (xi);

                       (xii) prior to any public offering of Transfer Restricted
     Securities, cooperate with the selling Holders and their counsel in
     connection with the registration and qualification of the Transfer
     Restricted Securities under the securities or Blue Sky laws of such
     jurisdictions as the selling Holders may request and do any and all other
     acts or things necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the
     applicable Registration Statement; provided, however, that neither the
     Company nor

                                       15
<PAGE>

     any Guarantor shall be required to register or qualify as a foreign
     corporation where it is not now so qualified or to take any action that
     would subject it to the service of process in suits or to taxation, other
     than as to matters and transactions relating to the Registration Statement,
     in any jurisdiction where it is not now so subject;

                       (xiii) in connection with any sale of Transfer Restricted
     Securities that will result in such securities no longer being Transfer
     Restricted Securities, cooperate with the Holders to facilitate the timely
     preparation and delivery of certificates representing Transfer Restricted
     Securities to be sold and not bearing any restrictive legends; and to
     register such Transfer Restricted Securities in such denominations and such
     names as the selling Holders may request at least two Business Days prior
     to such sale of Transfer Restricted Securities;

                       (xiv)  use their respective best efforts to cause the
     disposition of the Transfer Restricted 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 to consummate the disposition of such Transfer
     Restricted Securities, subject to the proviso contained in clause (xii)
     above;

                       (xv)   provide a CUSIP number for all Transfer Restricted
     Securities not later than the effective date of a Registration Statement
     covering such Transfer Restricted Securities and provide the Trustee under
     the Indenture with printed certificates for the Transfer Restricted
     Securities which are in a form eligible for deposit with the Depository
     Trust Company;

                       (xvi)  otherwise use their respective best efforts to
     comply with all applicable rules and regulations of the Commission, and
     make generally available to its security holders with regard to any
     applicable Registration Statement, as soon as practicable, a consolidated
     earnings statement meeting the requirements of Rule 158 (which need not be
     audited) covering a twelve-month period beginning after the effective date
     of the Registration Statement (as such term is defined in paragraph (c) of
     Rule 158 under the Act);

                       (xvii) cause the Indenture to be qualified under the TIA
     not later than the effective date of the first Registration Statement
     required by this Agreement and, in connection therewith, cooperate with the
     Trustee and the Holders to effect such changes to the Indenture as may be
     required for such Indenture to be so qualified in accordance with the terms
     of the TIA; and execute and use its best efforts to cause the Trustee to
     execute, all documents that may be required to effect such

                                       16
<PAGE>

     changes and all other forms and documents required to be filed with the
     Commission to enable such Indenture to be so qualified in a timely manner;
     and

                       (xviii) provide promptly to each Holder, upon request,
     each document filed with the Commission pursuant to the requirements of
     Section 13 or Section 15(d) of the Exchange Act.

            (d)     Restrictions on Holders. Each Holder agrees by
                    -----------------------
     acquisition of a Transfer Restricted Security that, upon receipt of the
     notice referred to in Section 6(c)(iii)(C) or any notice from the Company
     of the existence of any fact of the kind described in Section 6(c)(iii)(D)
     hereof (in each case, a "Suspension Notice"), such Holder will forthwith
                              -----------------
     discontinue disposition of Transfer Restricted Securities pursuant to the
     applicable Registration Statement until (i) such Holder has received copies
     of the supplemented or amended Prospectus contemplated by Section 6(c)(iv)
     hereof, or (ii) such Holder is advised in writing by the Company that the
     use of the Prospectus may be resumed, and has received copies of any
     additional or supplemental filings that are incorporated by reference in
     the Prospectus (in each case, the "Recommencement Date"). Each Holder
                                        -------------------
     receiving a Suspension Notice hereby agrees that it will either (i) destroy
     any Prospectuses, other than permanent file copies, then in such Holder's
     possession which have been replaced by the Company with more recently dated
     Prospectuses or (ii) deliver to the Company (at the Company's expense) all
     copies, other than permanent file copies, then in such Holder's possession
     of the Prospectus covering such Transfer Restricted Securities that was
     current at the time of receipt of the Suspension Notice. The time period
     regarding the effectiveness of such Registration Statement set forth in
     Section 3 or 4 hereof, as applicable, shall be extended by a number of days
     equal to the number of days in the period from and including the date of
     delivery of the Suspension Notice to the date of delivery of the
     Recommencement Date.

     SECTION 7.  REGISTRATION EXPENSES

            (a)     All expenses incident to the Company's and the Guarantors'

     Company, regardless of whether a Registration Statement becomes effective,
     including without limitation: (i) all registration and filing fees and

     disbursements of independent certified public accountants of the Company
     and the Guarantors (including the expenses of any special audit and comfort
     letters required by or incident to such performance).

            The Company will, in any event, bear its and the Guarantors'
     internal expenses (including, without limitation, all salaries and expenses
     of its officers and employees performing legal or accounting duties), the
     expenses of any annual audit and the fees and expenses of any Person,
     including special experts, retained by the Company or the Guarantors.

            (b)     In connection with any Registration Statement required by
     this Agreement (including, without limitation, the Exchange Offer
     Registration Statement and the Shelf Registration Statement), the Company
     and the Guarantors will reimburse the Initial Purchasers and the Holders of
     Transfer Restricted Securities who are tendering Series A Notes into in the
     Exchange Offer and/or selling or reselling Series A Notes or Series B Notes
     pursuant to the "Plan of Distribution" contained in the Exchange Offer
     Registration Statement or the Shelf Registration Statement, as applicable,
     for the reasonable fees and disbursements of not more than one counsel, who
     shall be chosen by the Holders of a majority in principal amount of the
     Transfer Restricted Securities for whose benefit such Registration
     Statement is being prepared.

     SECTION 8.  INDEMNIFICATION

            (a)     The Company and the Guarantors agree, jointly and severally,
     to indemnify and hold harmless each Holder, its directors, officers and
     each Person, if any, who controls such Holder (within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act), from and against
     any and all losses, claims, damages, liabilities, judgments, (including
     without limitation, any legal or other expenses incurred in connection with
     investigating or defending any matter, including any action that could give
     rise to any such losses, claims, damages, liabilities or judgments) caused
     by any untrue statement or alleged untrue statement of a material fact
     contained in any Registration Statement, preliminary prospectus or
     Prospectus (or any amendment or supplement thereto) provided by the Company
     to any Holder or any prospective purchaser of Series B Notes or registered
     Series A Notes, 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 not misleading, except insofar as such losses,
     claims, damages, liabilities or judgments are caused by an untrue statement
     or omission or alleged untrue statement or omission that is based

                                       18
<PAGE>

     upon information relating to any of the Holders furnished in writing to the
     Company by any of the Holders provided, however, that the Company shall not
     be liable under the indemnity agreement provided in this Section 8(a) to
     any indemnified party (as defined below) with respect to any preliminary
     prospectus to the extent that the Company shall sustain the burden of
     proving that any such loss, claim, damage, liability or judgment resulted
     from the fact that such indemnified party, in contravention of a
     requirement of applicable law, sold Transfer Restricted Securities to a
     person to whom such indemnified party failed to send or give, on or prior
     to the closing date of such sale, a copy of the Prospectus, as then amended
     or supplemented, if (i) the Company has previously furnished copies thereof
     (sufficiently in advance of such closing date to allow for distribution by
     the closing date) to such indemnified party, and the loss, claim, damage,
     liability or judgment of such indemnified party resulted from an untrue
     statement or omission or a material fact contained in or omitted from the
     preliminary prospectus that was corrected in the Prospectus as, if
     applicable, amended or supplemented prior to such closing date, and such
     Prospectus was required by law to be delivered at or prior to the written
     confirmation of sale to such person and (ii) such failure to give or send
     such Prospectus by such closing date to the party or parties asserting such
     loss, claim, damage, liability or judgment would have constituted a defense
     to the claim asserted by such person.

            (b)     Each Holder of Transfer Restricted Securities agrees,
     severally and not jointly, to indemnify and hold harmless the Company and
     the Guarantors, and their respective directors and officers, and each
     person, if any, who controls (within the meaning of Section 15 of the Act
     or Section 20 of the Exchange Act) the Company or the Guarantors, to the
     same extent as the foregoing indemnity from the Company and the Guarantors
     set forth in section (a) above, but only with reference to information
     relating to such Holder furnished in writing to the Company by such Holder
     expressly for use in any Registration Statement. In no event shall any
     Holder, its directors, officers or any Person who controls such Holder be
     liable or responsible for any amount in excess of the amount by which the
     total amount received by such Holder with respect to its sale of Transfer
     Restricted Securities pursuant to a Registration Statement exceeds (i) the
     amount paid by such Holder for such Transfer Restricted Securities and (ii)
     the amount of any damages that such Holder, its directors, officers or any
     Person who controls such Holder has otherwise been required to pay by
     reason of such untrue or alleged untrue statement or omission or alleged
     omission.

            (c)     In case any action shall be commenced involving any person
     in respect of which indemnity may be sought pursuant to Sec Section 8(a) or
     8(b) (the "indemnified party"), the indemnified party shall promptly notify
                -----------------
     the person against

                                       19
<PAGE>

     whom such indemnity may be sought (the "indemnifying person") in writing
                                             -------------------
     and the indemnifying party shall assume the defense of such action,
     including the employment of counsel reasonably satisfactory to the
     indemnified party and the payment of all fees and expenses of such counsel,
     as incurred (except that in the case of any action in respect of which
     indemnity may be sought pursuant to both Sections 8(a) and 8(b), a Holder
     shall not be required to assume the defense of such action pursuant to this
     Section 8(c), but may employ separate counsel and participate in the
     defense thereof, but the fees and expenses of such counsel, except as
     provided below, shall be at the expense of the Holder). Any indemnified
     party shall have the right to employ separate counsel in any such action
     and participate in the defense thereof, but the fees and expenses of such
     counsel shall be at the expense of the indemnified party unless (i) the
     employment of such counsel shall have been specifically authorized in
     writing by the indemnifying party, (ii) the indemnifying party shall have
     failed to assume the defense of such action or employ counsel reasonably
     satisfactory to the indemnified party or (iii) the named parties to any
     such action (including any impleaded parties) include both the indemnified
     party and the indemnifying party, and the indemnified party shall have been
     advised by such counsel that there may be one or more legal defenses
     available to it which are different from or additional to those available
     to the indemnifying party (in which case the indemnifying party shall not
     have the right to assume the defense of such action on behalf of the
     indemnified party). In any such case, the indemnifying party shall not, in
     connection with any one action or separate but substantially similar or
     related actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the fees and expenses of more
     than one separate firm of attorneys (in addition to any local counsel) for
     all indemnified parties and all such fees and expenses shall be reimbursed
     as they are incurred. Such firm shall be designated in writing by a
     majority of the Holders, in the case of the parties indemnified pursuant to
     Section 8(a), and by the Company and Guarantors, in the case of parties
     indemnified pursuant to Section 8(b). The indemnifying party shall
     indemnify and hold harmless the indemnified party from and against any and
     all losses, claims, damages, liabilities and judgments by reason of any
     settlement of any action (i) effected with its written consent or (ii)
     effected without its written consent if the settlement is entered into more
     than twenty business days after the indemnifying party shall have received
     a request from the indemnified party for reimbursement for the fees and
     expenses of counsel (in any case where such fees and expenses are at the
     expense of the indemnifying party) and, prior to the date of such
     settlement, the indemnifying party shall have failed to comply with such
     reimbursement request. No indemnifying party shall, without the prior
     written consent of the indemnified party, effect any settlement or
     compromise of, or consent to the entry of judgment with respect to, any
     pending or threatened action in respect of which the indemnified party is
     or could have been a party and indemnity or contribution may be or could
     have been sought

                                       20
<PAGE>


hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

          (d)  To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company and
the Guarantors, on the one hand, and the Holders, on the other hand, from their
sale of Transfer Restricted Securities or (ii) if the allocation provided by
clause 8(d)(i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
8(d)(i) above but also the relative fault of the Company and the Guarantors, on
the one hand, and of the Holder, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors, on the one
hand, and of the Holder, on the other hand, shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or such Guarantor, on the one hand, or by
the Holder, on the other hand, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and judgments referred to above shall be deemed to
include, subject to the limitations set forth in the second paragraph of Section
8(a), any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim.

          The Company, the Guarantors and each Holder agree that it would not be
just and equitable if contribution pursuant to this Section 8(d) were determined
by pro rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating

                                       21
<PAGE>

or defending any matter, including any action that could have given rise to such
losses, claims, damages, liabilities or judgments. Notwithstanding the
provisions of this Section 8, no Holder, its directors, its officers or any
Person, if any, who controls such Holder shall be required to contribute, in the
aggregate, any amount in excess of the amount by which the total received by
such Holder with respect to the sale of Transfer Restricted Securities pursuant
to a Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages which such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

SECTION 9. RULE 144A and RULE 144

          The Company and each Guarantor agrees with each Holder, for so long as
any Transfer Restricted Securities remain outstanding and during any period in
which the Company or such Guarantor (i) is not subject to Section 13 or 15(d) of
the Exchange Act, to make available, upon request of any Holder, to such Holder
or beneficial owner of Transfer Restricted Securities in connection with any
sale thereof and any prospective purchaser of such Transfer Restricted
Securities designated by such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to
Section 13 or 15 (d) of the Exchange Act, to make all filings required thereby
in a timely manner in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144.

SECTION 10.    MISCELLANEOUS

          (a) Remedies.  The Company and the Guarantors acknowledge and agree
              --------
that any failure by the Company and/or the Guarantors to comply with their
respective obligations under Sections 3 and 4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders  for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Guarantor's obligations under
Sections 3 and 4 hereof.  The Company and the Guarantors further agree to waive
the defense in any action for specific performance that a remedy at law would be
adequate.

                                       22
<PAGE>

          (b) No Inconsistent Agreements.  Neither the Company nor any Guarantor
              --------------------------
will, on or after the date of this Agreement, enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any Guarantor is currently a party to any agreement
granting any registration rights with respect to its securities to any Person.
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 Company's and
the Guarantors' securities under any agreement in effect on the date hereof.

          (c) Amendments and Waivers.  The provisions of this Agreement may not
              ----------------------
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 10(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates).  Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

          (d) Third Party Beneficiary.  The Holders shall be third party
              -----------------------
beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders hereunder.

          (e) Notices.  All notices and other communications provided for or
              -------

subsequent Holders; provided, that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Transfer Restricted Securities in
violation of the terms hereof or of the Purchase Agreement or the Indenture.  If

manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held
