(including the delivery of the Prospectus contained therein).

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 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 60 days after the Closing Date (such
60th day being the "FILING DEADLINE"), (ii) use its reasonable best efforts to
cause such Exchange Offer Registration Statement to become effective at the
earliest possible time, but in no event later than 135 days after the Closing
Date (such 135th 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 Debentures to be made under the Blue Sky laws of
such United States jurisdictions as are necessary to permit Consummation of the
Exchange Offer, PROVIDED, HOWEVER, that the Company shall not be required in
connection therewith to register or qualify as a foreign corporation in any
jurisdiction where it is not now 


                                       3



so registered or qualified or to take any action that would subject it to 
service of process in suits or to taxation, other than as to matters and 
transactions relating to the Exchange Offer Registration Statement, in any 
jurisdiction where it is not now so subject, 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 Debentures to be offered in 
exchange for the Series A Debentures that are Transfer Restricted Securities 
and (ii) resales of Series B Debentures by Broker-Dealers that tendered into 
the Exchange Offer Series A Debentures that such Broker-Dealer acquired for 
its own account as a result of market making activities or other trading 
activities (other than Series A Debentures acquired directly from the Company 
or any of its Affiliates) as contemplated by Section 3(c) below.

          (b)  The Company shall use its reasonable 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 shall cause the Exchange Offer to comply
with all applicable federal and state securities laws.  No securities other than
the Series B Debentures (and guarantees thereof, if any) shall be included in
the Exchange Offer Registration Statement.  The Company shall use its reasonable
best efforts to cause the Exchange Offer to be Consummated on or prior to 30
Business Days after the Exchange Offer Registration Statement has become
effective (such 30th Business 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 Debentures 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.  

          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
Debentures received by such Broker-Dealer in the Exchange Offer, the Company
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
Debentures by Broker-Dealers, the Company agrees to use its reasonable 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 

                                       4



have been sold pursuant thereto.  The Company 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.

Section 4.     SHELF REGISTRATION.

          (a)  SHELF REGISTRATION.  If (i) the Exchange Offer is not permitted
by applicable law (after the Company has 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 prior to the 20th day following the
Consummation of the Exchange Offer 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 Debentures 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
Debentures acquired directly from the Company or any of its Affiliates, then the
Company shall:

               (x)  use its best efforts to 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)  use its best efforts to cause such Shelf Registration
Statement to become effective on or prior to 90 days after the obligation to
file such Shelf Registration Statement arises (such 90th 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 shall use its best efforts to keep any Shelf Registration
Statement required by this Section 4(a) continuously effective, supplemented,
amended and 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 when all Transfer Restricted Securities covered by such Shelf
Registration Statement have been sold pursuant thereto.

                                       5




          (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 or prospectus supplement
thereto.  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
(except in the situation described in Section 4(a)(i) above when Section
4(a)(x)(i) has been satisfied) 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 Business Days by a post-effective amendment to such Registration
Statement (or a new Registration Statement) that cures such failure and that is
itself declared effective within five Business 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 hereby agrees 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 $.25 per week
per $1,000 in principal amount of Transfer Restricted Securities; PROVIDED that
the Company 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 

                                       6



fully set forth in the Indenture and the Debentures.  Notwithstanding the 
fact that any securities for which liquidated damages are due cease to be 
Transfer Restricted Securities, all obligations of the Company 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.

Section 6.     REGISTRATION PROCEDURES.

          (a)  EXCHANGE OFFER REGISTRATION STATEMENT.  In connection with the
Exchange Offer, the Company shall (x) comply with all applicable provisions of
Section 6(c) below, (y) use its best efforts to effect such exchange and to
permit the resale of Series B Debentures by any Broker-Dealer that tendered in
the Exchange Offer Series A Debentures 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 Debentures 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 hereby agrees to seek a no-action
     letter or other favorable decision from the Commission allowing the Company
     to Consummate an Exchange Offer for such Transfer Restricted Securities. 
     The Company hereby agrees to pursue the issuance of such a decision to the
     Commission staff level.  In connection with the foregoing, the Company
     hereby agrees 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.  Notwithstanding the foregoing,
     the Company shall not be required to take commercially unreasonable action
     to comply with the requests of the Commission referred to in the previous
     sentence in order to secure a favorable resolution.

               (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 (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 Debentures to be issued in the Exchange Offer and (C) it is
     acquiring the Series B Debentures 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 Debentures
     shall acknowledge and agree that, if the resales are of Series B Debentures
     obtained by such Holder in exchange for Series A Debentures 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) 

                                       7



     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 shall provide a supplemental letter to the
     Commission (A) stating that the Company is 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 the Company has not entered into any arrangement or
     understanding with any Person to distribute the Series B Debentures to be
     received in the Exchange Offer and that, to the best of the Company's
     information and belief, each Holder participating in the Exchange Offer is
     acquiring the Series B Debentures in its ordinary course of business and
     has no arrangement or understanding with any Person to participate in the
     distribution of the Series B Debentures 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 shall a)(i) comply with all the provisions
of Section 6(c) below and use its 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 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, and

          (ii) issue, upon the request of any Holder or purchaser of Series A
Debentures covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Debentures having an aggregate principal amount equal to the
aggregate principal amount of Series A Debentures sold pursuant to the Shelf
Registration Statement and surrendered to the Company for cancellation; the
Company shall register Series B Debentures on the Shelf Registration Statement
for this purpose and issue the Series B Debentures 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
shall:

               (i)    use its 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 

                                       8



     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 shall
     file promptly an appropriate amendment to such Registration Statement or 
     supplement such Prospectus, as applicable, curing such defect, and, if 
     Commission review is required, use its 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 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 shall use its 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 

                                       9



     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, 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 after the receipt thereof.  A 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 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 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)  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 cause the Company's 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);

                                       10



               (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
     hereby consents to the use (in accordance with law) of the Prospectus and
     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 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 by (x) the President or any Vice President
               and (y) a principal financial or accounting officer of the
               Company, 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 such date, of counsel
               for the Company covering, to the extent relevant at such time,
               matters similar to those set forth in paragraph (e) of Section 9
               of the Purchase Agreement and such other matter 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,
               representatives of the independent public accountants for the
               Company 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 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 

                                       11



               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 and statistical data included in any 
               Registration Statement contemplated by this Agreement or the 
               related Prospectus; and

                              (3)    a customary comfort letter, dated such
               date, 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 in form and substance reasonably satisfactory
               to the Holders; 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 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 the Company
     shall not 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;


                                       12




               (xiv)  use its 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 its 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 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) until the disposition of all Transfer Restricted
     Securities held by any Holder, provide promptly to such 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 

                                       13



days equal to the number of days in the period from and including the date of 
delivery of the Suspension Notice to the Recommencement Date.

SECTION 7.     REGISTRATION EXPENSES.

          (a)  All expenses incident to the Company's 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
securities laws; (iii) all expenses of printing (including printing certificates
for the Series B Debentures and printing of Prospectuses), (iv) reasonable
messenger, delivery service and telephone charges; (v) all fees and
disbursements of counsel for the Company, and, in accordance with Section 7(b)
below, the Holders of Transfer Restricted Securities; (vi) all application and
filing fees in connection with listing Debentures on a national securities
exchange or automated quotation system pursuant to the requirements hereof, in
the event the Debentures are so listed; and (vii) all fees and disbursements of
independent certified public accountants of the Company (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 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.

          (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 will reimburse the
Initial Purchaser and the Holders of Transfer Restricted Securities who are
tendering Series A Debentures into in the Exchange Offer and/or selling or
reselling Series A Debentures or Series B Debentures 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 Latham & Watkins,
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 agrees 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, 


                                       15



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 Debentures or registered Series A Debentures, or caused 
by any omission or alleged omission to state therein a material fact required 
to be stated therein or necessary to make the statements therein, in light of 
the circumstances under which they were made, 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 its 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, to the
same extent as the foregoing indemnity from the Company 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 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 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, 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
or 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 


                                       15



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, 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, 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, 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, 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 Section 8(c), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.

          The Company 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, 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 


                                       16



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 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, 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 acknowledge and agree that any failure by
the Company to comply with its 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 obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 3 and
4 hereof.  The Company further agree to waive the defense in any action for
specific performance that a remedy at law would be adequate.

          (b)  NO INCONSISTENT AGREEMENTS.  The Company will not, 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.  The Company has
not previously entered into any agreement that grants 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 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 


                                       17



tendered pursuant to such Exchange Offer, may be given by the Holders of a 
majority of the outstanding principal amount of Transfer Restricted 
Securities being tendered pursuant to such Exchange Offer.

          (d)  THIRD PARTY BENEFICIARY.  The Holders shall be third party
beneficiaries of the agreements made hereunder between the Company, 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

of and be binding upon the successors and assigns of each of the parties,
including without limitation and without the need for an express assignment,
subsequent Holders; PROVIDED, that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Transfer Restricted Securities in

any transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by

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.

                                       18
