SECTION 2.        HOLDERS

         A Person is deemed to be a holder of 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 (the "EXCHANGE OFFER FILING DATE"), but in no
event later than 60 days after the Closing Date (such 60th 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 150 days after the Closing Date (such 150th 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 


                                       4
   5
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 registration of the Series B Notes to be
offered in exchange for Series A Notes that are Transfer Restricted Securities
and to permit 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 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 30th day being the "CONSUMMATING 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 Transfer Restricted
Securities acquired directly from the Company or any Affiliate of the Company),
may exchange such Transfer Restricted Securities pursuant to the Exchange Offer;
however, such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus to be provided by
the Company, 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
and that the Prospectus contained in the Exchange Offer Registration Statement
may be used by such Broker-Dealer to satisfy such prospectus delivery
requirement. 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).

         To the extent necessary to ensure that the Prospectus contained in the
Exchange Offer 


                                       5
   6
Registration Statement is continuously 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 and amended as required by the provisions of Section
6(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
shall promptly provide sufficient copies of the latest version of such
Prospectus to such Broker-Dealer promptly upon request, and in no event later
than one day after such request, at any time during such period.

SECTION 4.        SHELF REGISTRATION

         (a) Shelf Registration. If (i) (A) the Exchange Offer is not permitted
by applicable law or Commission policy (after the Company and the Guarantors
have complied with the procedures set forth in Section 6(a)(i) below) or (B) for
any other reason the Exchange Offer is not Consummated within 180 days after the
Closing Date or (ii) if any Holder of Transfer Restricted Securities notifies
the Company prior to the 20th business day 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
as promptly as practicable deliver to the Holders and the Trustee written notice
thereof (the "Shelf Notice"), and the Company 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 (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)(A) 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).


                                       6
   7
         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 and amended as required by and subject to
the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure
that it is available for sales of Transfer Restricted Securities by the Holders
thereof entitled to the benefit of this Section 4(a), and to ensure that it
conforms 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 when all Transfer
Restricted Securities covered by such Shelf Registration Statement have been
sold pursuant thereto (the "Effectiveness Period"). No securities other than
Transfer Restricted Securities shall be included in any Shelf Registration
Statement.

         (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
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 immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective immediately (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 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 $.50 per week per $1,000 in principal amount of Transfer
Restricted Securities; provided that the Company 


                                       7
   8
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 by the Company 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. All obligations of the Company and the Guarantors set
forth in the preceding paragraph that are outstanding with respect to any
Transfer Restricted Security at the time such security ceases to be a Transfer
Restricted Security shall survive until such time as all such obligations with
respect to such security shall have been satisfied in full.

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 that tendered Notes 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) 


                                       8

     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.
     Each Holder using the Exchange Offer to participate in a distribution of
     the Series B Notes hereby acknowledges and agrees 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. (available June 5, 1991) and Exxon Capital Holdings Corporation
     (available May 13, 1988), as interpreted in the Commission's letter to
     Shearman & Sterling dated July 2, 1993, and similar no-action letters
     (including, if applicable, any no-action letter 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 Co., Inc. (available June 5, 1991) as
     interpreted in the Commission's letter to 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 the Guarantors 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 (x) comply with all
the provisions of Section 6(c) below and (y) use their respective best efforts
to effect such registration to permit the sale of the Transfer Restricted


                                       9
   10
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 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.

         (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 a
     material misstatement or omission 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 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 the selling Holders promptly and, if requested by such
     Persons, 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 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 


                                       10
   11
     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 the Initial Purchaser and each selling Holder named
     in any Registration Statement or Prospectus 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 selling Holders in connection with such sale, if any, for a
     period of at least five Business Days, 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 selling Holders shall reasonably
     object within five Business Days after the receipt thereof. A selling
     Holder shall be deemed to have reasonably objected to such filing if such
     Registration Statement, amendment, Prospectus or supplement, as applicable,
     as proposed to be filed, contains a material misstatement or omission 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 the selling Holders 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 selling Holders may reasonably
     request;

             (vii) make available at reasonable times for inspection by the
     selling Holders participating in any disposition pursuant to such
     Registration Statement and any attorney or 


                                       11
   12
     accountant retained by such selling 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
     selling 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 selling 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 selling 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 selling 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 selling 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 any amendment or supplement thereto by each of the
     selling Holders in connection with the offering and the sale of the
     Transfer Restricted Securities covered by the Prospectus or any amendment
     or supplement thereto;

             (xi) in the case of a Shelf Registration Statement only, upon the
     request of any selling 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 such Registration Statement contemplated by this Agreement as may be
     reasonably requested by any Holder of Transfer Restricted Securities in
     connection with any sale or resale pursuant to such Registration Statement.
     In such connection, the Company and the Guarantors shall:

             (A) upon request of any selling Holder, furnish (or in the case of
         paragraphs (2) and (3), use its best efforts to cause to be furnished)
         to each selling 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 the Guarantors by (x) 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 


                                       12
   13
             thereof, the matters set forth in paragraphs (a) and (ee) of 
             Section 6 and (a) and (b) of Section 9 of the Purchase Agreement 
             and such other similar matters as the selling 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
             (j) of Section 9 of the Purchase Agreement and such other matter as
             the selling Holders 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, representatives of the
             independent public accountants for the Company and the Guarantors
             and have 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 (relying as to materiality to the extent such
             counsel deems appropriate upon the statements of officers and other
             representatives of the Company and the Guarantors and without
             independent check or verification), no facts came to such counsel's
             attention that caused such counsel to believe that the 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(1) 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
         clause (A) above and with any customary 


                                       13
   14
         conditions contained in the 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 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) issue, upon the request of any Holder 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 amount of Series A Notes surrendered to the Company by such
     Holder in exchange therefor or being sold by such Holder; such Series B
     Notes to be registered in the name of such Holder or in the name of the
     purchaser(s) of such Series B Notes, as the case may be; in return, the
     Series A Notes held by such Holder shall be surrendered to the Company for
     cancellation;

             (xiv) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the selling 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;

             (xv) 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;

             (xvi) 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;

             (xvii) 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


                                       14
   15
     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);

             (xix) 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 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

             (xx) use their respective best efforts to cause the Transfer
Restricted Securities or the Series B Notes, as applicable, covered by an
effective registration statement required by Section 3 or Section 4 hereof to be
rated by one or two rating agencies, if and as so requested by the Holders of a
majority in aggregate principal amount of Transfer Restricted Securities
relating to such registration statement or the managing underwriters in
connection therewith, if any;

             (xxi) 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.

             (xxii) use their respective best efforts to take all other steps
necessary to effect the registration of the Transfer Restricted Securities
covered by a Registration Statement contemplated hereby.

         (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.

   16
SECTION 7.        REGISTRATION EXPENSES

         (a) All expenses incident to the Company's and the Guarantors'
performance of or compliance with this Agreement will be borne by the Company,
regardless of whether a Registration Statement becomes effective, including
without limitation: (i) all registration and filing fees and expenses; (ii) all
fees and expenses of compliance with federal securities and state Blue Sky or

(viii) all fees and disbursements of independent certified public accountants of

         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

         (b) In connection with any Registration Statement required by this

disbursements of not more than one counsel, who shall be Skadden, Arps, Slate,
Meagher & Flom LLP, unless another firm 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, jointly and severally, agree to
indemnify and hold harmless each Holder, its directors, its 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


                                       16
   17
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 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 upon information relating to
any of the Holders furnished in writing to the Company by any of the Holders.

         (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 to each of the Indemnified Holders, but only
with reference to information relating to such Indemnified Holder furnished in
writing to the Company by such Indemnified Holder expressly for use in any
Registration Statement. In no event shall any Indemnified Holder be liable or
responsible for any amount in excess of the amount by which the total amount
received by such Indemnified Holder with respect to its sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (i) the
amount paid by such Indemnified Holder for such Transfer Restricted Securities
and (ii) the amount of any damages that such Indemnified 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 Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing
(provided that the failure to give such notice shall not relieve the
indemnifying party of its obligations under Section 8 (a) or (b) unless and only
to the extent that the indemnifying party is materially prejudiced by the
failure to notify) 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), an Indemnified 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 Indemnified 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 promptly 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 separate 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


                                       17
   18
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
Indemnified Holders, in the case of the parties indemnified pursuant to Section
8(a), and by the Company, 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 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 Indemnified 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 Indemnified 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 and the Guarantors, on the one
hand, or by the Indemnified 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 


                                       18
   19
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 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 or its
related Indemnified Holders 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 its Transfer Restricted Securities pursuant to a
Registration Statement exceeds the sum of (A) the amount paid by such Holder for
such Transfer Restricted Securities plus (B) 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 of the Holders hereunder and not
joint.

SECTION 9.            RULE 144 AND RULE 144A

         The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder of Transfer Restricted Securities, to any
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 Purchaser 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 Purchaser or
any Holder may 


                                       19
   20
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.

         (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 the Guarantor has previously entered into 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 of its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose securities are being tendered pursuant to the Exchange Offer
and that does not affect directly or indirectly the rights of other Holders
whose 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 Purchaser, 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
permitted hereunder shall be made in writing by hand-delivery, first-class mail

of and be binding upon the successors and assigns of each of the parties,

subsequent Holders of Transfer Restricted Securities; provided, that nothing

Restricted Securities such Person shall be conclusively deemed to have agreed to
be bound by and to perform all of the terms and provisions of this Agreement,
including the restrictions on resale set forth in this Agreement and, if
applicable, the Purchase Agreement, and such Person shall be entitled to receive
the benefits hereof.

         (g) Counterparts. This Agreement may be executed in any number of
