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) or Commission policy, each of the Company (and, to the extent of
the Guarantees, the Guarantors) shall (i) cause the Exchange Offer Registration
Statement to be filed with the Commission as soon as practicable after the
Closing Date, but in no event later than 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 be declared effective by
the Commission at the earliest possible time, but in no event later than 180
days after the Closing Date (such 180th day being the "EFFECTIVENESS
DEADLINE"), (iii) in connection with the foregoing, (A) file all pre-effective
amendments to such Exchange Offer Registration Statement as may be necessary in
order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the Series B Notes to be
made under the Blue Sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer, and (iv) upon the effectiveness of such
Exchange Offer Registration Statement, commence and Consummate the Exchange





                                      -3-
   5
Offer.  The Exchange Offer shall be on the appropriate form permitting (i)
registration of the Series B Notes to be offered in exchange for the Series A
Notes that are Transfer Restricted Securities and (ii) resales of Series B
Notes by Broker-Dealers that are validly 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, if permissible under applicable law or
Commission policy.

         (b)     The Company (and, to the extent of the Guarantees, the
Guarantors) shall use their respective 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 (and, to the extent of the Guarantees, 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, to the extent of the Guarantees, the Guarantors) shall use their
respective reasonable 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 "CONSUMMATION DEADLINE");
provided, however, that the Consummation Deadline shall be subject to extension
for up to an additional 10 Business Days with the written consent of the
Initial Purchasers.

         (c)     The Company shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted
Securities that were acquired for the account of such Broker-Dealer as a result
of market-making activities or other trading activities (other than Series A
Notes acquired directly from the Company or any Affiliate of the Company), may
exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission as a result of a change in policy, rules or
regulations after the date of this Agreement.

         Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement.  To the extent necessary to ensure that the prospectus
contained in the Exchange Offer Registration Statement is available for sales
of Series B Notes by Broker-Dealers, the Company and the Guarantors agree to
use their respective 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 Sections 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 180 calendar days from the Consummation Deadline or such
shorter period as will terminate when all Transfer Restricted Securities
covered by such Registration Statement have been sold pursuant thereto.  The
Company and the Guarantors shall provide sufficient copies of the latest
version of such Prospectus to such Broker-Dealers, promptly upon request, at
any time during such period in order to facilitate such resales.

SECTION 4.       SHELF REGISTRATION



         (a)     Shelf Registration.  If (i) 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 (ii) any Holder of Transfer Restricted Securities shall give written
notice (a "Holder Resale Notice") to the Company on or prior to the 20th
Business Day following the Consummation Deadline that (A) such Holder was
prohibited by applicable law or Commission policy from participating in the
Exchange Offer, (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, to the extent of the Guarantees,
the Guarantors) shall:

         (x) cause to be filed, on or prior to the 45th day 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 Holder Resale Notice (such 45th
day being 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) (in either event, the "SHELF REGISTRATION STATEMENT"),
relating to all Transfer Restricted Securities the Holders of which shall have
previously provided the information required pursuant to Section 4(b) hereof,
and



         (y) shall use their respective reasonable best efforts to cause such
Shelf Registration Statement to be declared effective by the Commission on or
prior to the 180th day after the Filing Deadline for the Shelf Registration
Statement (such 180th day being 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 law or Commission
policy (i.e., clause (a)(i) above), then the filing of the Exchange Offer
Registration Statement shall be deemed to satisfy the requirements of clause
(x) above; provided that, in such event, the Company shall remain obligated to
meet the Effectiveness Deadline set forth in clause (y).



         To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Company (and, to the extent of the Guarantees, the Guarantors)
shall use their respective reasonable 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, until the earliest of: (i) the date that is two
years (as extended pursuant to Section 6(d)) following the Closing Date, (ii)
the Consummation of the Exchange Offer with respect to all Transfer Restricted
Securities and the expiration of 20 Business Days after the Consummation
thereof if during such 20 Business Day period no Holder Resale Notice shall
have been received by the Company or (iii) the date when all Transfer
Restricted Securities covered by such Shelf Registration Statement have been
sold pursuant thereto.





                                      -5-
   7
         (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.

         (c)     Black Out Period.  During any consecutive 365 day period, the
Company may suspend the effectiveness of the Shelf Registration Statement on up
to two occasions for a period of not more than 45 consecutive days (whereafter
a Registration Default shall occur) if there is a possible acquisition or
business combination or other transaction, business development or event
involving the Company that may require disclosure in the Shelf Registration
Statement and the Board of Directors of the Company determines in the exercise
of its reasonable judgment that such disclosure is not in the best interests of
the Company and its stockholders or obtaining any financial statements relating
to a possible acquisition or business combination required to be included in
the Shelf Registration Statement would be impracticable.  In such a case, the
Company shall promptly notify the Holders of the suspension of the Shelf
Registration Statement's effectiveness, provided that such notice shall not
require the Company to disclose the possible acquisition or business
combination or other transaction, business development or event if the Board of
Directors of the Company determines in good faith that such acquisition or
business combination or other transaction, business development or event should
remain confidential.  Upon the abandonment, consummation, or termination of the
possible acquisition or business combination, the suspension of the use of the
Shelf Registration Statement pursuant to this Section 4(c) shall cease and the
Company shall promptly comply with Section 6(c)(ii) hereof and notify the
Holders that disposition of Transfer Restricted Securities may be resumed.  The
Company shall extend the relevant period set forth in Section 4(a) during which
it is required to keep the Shelf Registration Statement effective by the number
of days the use of the Shelf Registration Statement is suspended pursuant to
this Section 4(c).

SECTION 5.       LIQUIDATED DAMAGES

         If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation
Deadline or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within 5 days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective within 10 days of filing such
post-effective amendment to such Registration Statement (each such event
referred to in clauses (i) through (iv), a "REGISTRATION DEFAULT"), then the
Company and the Guarantors hereby jointly and severally agree to pay to each
Holder of Transfer Restricted Securities affected thereby liquidated damages
("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





                                      -6-
   8
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 $.20 per week per $1,000 in principal amount of
Transfer Restricted Securities; provided that the Company and the Guarantors
shall in no event be required to pay Liquidated Damages for more than one
Registration Default at any given time.  Notwithstanding anything to the
contrary set forth herein, (1) upon filing of the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement), in the
case of (i) above, (2) upon the effectiveness of the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (ii) above, (3) upon Consummation of the Exchange
Offer, in the case of (iii) above, or (4) upon the filing of a post-effective
amendment to the Registration Statement or an additional Registration Statement
that causes the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement) to again be declared effective or made usable
in the case of (iv) above, the Liquidated Damages payable with respect to the
Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

         All accrued Liquidated Damages shall be paid to the record Holders
entitled thereto, in the manner provided for the payment of interest in the
Indenture, on each Interest Payment Date, as more fully set forth in the
Indenture and the Notes.  Notwithstanding the fact that any securities for
which Liquidated Damages are due cease to be Transfer Restricted Securities,
all obligations of the Company and the Guarantors to pay Liquidated Damages
with respect to securities shall survive until such time as such obligations
with respect to such securities shall have been satisfied in full.

SECTION 6.       REGISTRATION PROCEDURES

         (a)     Exchange Offer Registration Statement.  In connection with the
Exchange Offer, the Company (and, to the extent of the Guarantees, the
Guarantors) shall (x) comply with all applicable provisions of Section 6(c)
below, (y) use their respective reasonable best efforts to effect such exchange
and to permit the resale of Series B Notes by Broker- Dealers that tendered in
the Exchange Offer Series A Notes that such Broker-Dealer acquired for its own
account as a result of its market making activities or other trading activities
(other than Series A Notes acquired directly from the Company or any of its
Affiliates) being sold in accordance with the intended method or methods of
distribution thereof, and (z) comply with all of the following provisions:

                 (i)      If, following the date hereof there has been
         announced a change in Commission policy with respect to exchange
         offers such as the Exchange Offer, that in the reasonable opinion of
         counsel to the Company raises a 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, including oral advice from the staff of
         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 but shall not be required to
         take commercially unreasonable action to effect a change of Commission
         policy.  In connection with the foregoing, the Company and the
         Guarantors hereby agree to take all such other actions (other than
         such actions as may be commercially unreasonable) 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





                                      -7-
   9
         which such counsel has concluded that such an Exchange Offer should be
         permitted and (C) diligently pursuing a resolution (which need not be
         favorable) by the Commission staff.

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

                 (i) comply with all the provisions of Section 6(c) below and
use their respective reasonable best efforts to effect such registration to
permit the sale of the Transfer Restricted Securities being sold in accordance
with the intended method or methods of distribution thereof (as indicated in
the information furnished to the Company pursuant to Section 4(b) hereof), and
pursuant thereto the Company (and, to the





                                      -8-
   10
extent of the Guarantees, the Guarantors) will prepare and file with the
Commission a Registration Statement relating to the registration on any
appropriate form under the Act, which form shall be available for the sale of
the Transfer Restricted Securities in accordance with the intended method or
methods of distribution thereof within the time periods and otherwise in
accordance with the provisions hereof.

                 (ii) issue, upon the request of any Holder or purchaser of
Series A Notes covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Notes having an aggregate principal amount equal to the
aggregate principal amount of Series A Notes sold pursuant to the Shelf
Registration Statement and surrendered to the Company for cancellation; the
Company shall register Series B Notes on the Shelf Registration Statement for
this purpose and issue the Series B Notes to the purchaser(s) of securities
subject to the Shelf Registration Statement in the names as such purchaser(s)
shall designate.

         (c)     General Provisions.  In connection with any Registration
Statement and any related Prospectus required by this Agreement to permit the
sale or resale of Transfer Restricted Securities (including, without
limitation, any Registration Statement and the related Prospectus required to
permit resales by Broker-Dealers), the Company (and, to the extent of the
Guarantees, the Guarantors) shall:

                 (i)      use their respective reasonable best efforts to keep
         such Registration Statement continuously effective and provide all
         requisite financial statements for the period specified in Section 3
         or 4 of this Agreement, as applicable.  Upon the occurrence of any
         event that would cause any such Registration Statement or the
         Prospectus contained therein (A) to contain an untrue statement of
         material fact or omit to state any material fact necessary to make the
         statements therein not misleading or (B) not to be effective and
         usable for resale of Transfer Restricted Securities during the period
         required by this Agreement, the Company (and, to the extent of the
         Guarantees, the Guarantors) shall file promptly an appropriate
         amendment to such Registration Statement curing such defect, and, if
         Commission review is required, use their respective reasonable best
         efforts to cause such amendment to be declared effective as soon as
         reasonably 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, or such shorter period as will terminate when all Transfer
         Restricted Securities covered by such Registration Statement have been
         exchanged or sold or until such securities no longer constitute
         Transfer Restricted Securities or are no longer outstanding; cause,
         subject to Section 4(c), 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





                                      -9-
   11
         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, and (D) of the existence of any fact or the
         happening of any event that makes any statement of a material fact
         made in the Registration Statement, the Prospectus, any amendment or
         supplement thereto or any document incorporated by reference therein
         untrue, or that requires the making of any additions to or changes in
         the Registration Statement in order to make the statements therein not
         misleading, or that requires the making of any additions to or changes
         in the Prospectus in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading.
         If at any time the Commission shall issue any stop order suspending
         the effectiveness of the Registration Statement, or any state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption from qualification of
         the Transfer Restricted Securities under state securities or Blue Sky
         laws, the Company (and, to the extent of the Guarantees, the
         Guarantors) shall use their respective reasonable best efforts to
         obtain the withdrawal or lifting of such order at the earliest
         practicable 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 managing underwriters, if any, or any
         Holder who is required to deliver a Prospectus in connection with an
         Exchange Offer or who is otherwise named in a Prospectus in connection
         with such exchange or sale (the "Specified Holders"), 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 Specified 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 Specified 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 omits 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, if requested by any Holders within five Business Days
         after receipt of notification thereof from the Company, provide copies
         of such document to each Holder in connection with such exchange or
         sale, if any, make the Company's and the Guarantors' representatives
         available for discussion of such document and other customary due
         diligence matters, and include such information in such document prior
         to the filing thereof as such Holders may reasonably request;





                                      -10-
   12
                 (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 the Guarantors and cause the Company's
         and the Guarantors' officers, directors and employees to supply all
         information reasonably requested by any such Holder, attorney or
         accountant in connection with such Registration Statement or any
         post-effective amendment thereto subsequent to the filing thereof and
         prior to its effectiveness;



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



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



                 (x)      deliver to each Holder without charge, as many copies
         of the Prospectus (including each preliminary prospectus) and any
         amendment or supplement thereto as such Persons reasonably may
         request; the Company (and, to the extent of the Guarantees, the
         Guarantors) hereby consent 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 Specified Holder or the
         managing underwriters, if any, enter into such agreements (including
         underwriting agreements) and make such representations and warranties
         and take all such other customary or appropriate actions as are
         reasonably requested in connection therewith in order to expedite or
         facilitate the disposition of the Transfer Restricted Securities
         pursuant to the applicable Registration Statement contemplated by this
         Agreement as may be reasonably requested by any Specified Holder in
         connection with any sale or resale pursuant to any applicable
         Registration Statement.  In such connection, the Company (and, to the
         extent of the Guarantees, the Guarantors) shall:



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



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





                                      -11-
   13
                                  (2)      an opinion, dated the date of
                          Consummation of the Exchange Offer or the date of
                          effectiveness of the Shelf Registration Statement, as
                          the case may be, of counsel for the Company and the
                          Guarantors covering matters similar to those set
                          forth in paragraph (e) of Section 9 of the Purchase
                          Agreement and such other matters as such Specified
                          Holder may reasonably request, and in any event
                          including a statement to the effect that such counsel
                          has participated in conferences with officers and
                          other representatives of the Company and the
                          Guarantors, 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 investigated or
                          independently verified, and does not assume any
                          responsibility for, 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, in light of the circumstances
                          under which they were made, 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 or statistical data included in any
                          Registration Statement contemplated by this Agreement
                          or the related Prospectus; and



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



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





                                      -12-
   14
                 (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)   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,
         including global certificates, representing Transfer Restricted
         Securities to be sold and not bearing any restrictive legends; and, in
         the case of certificated Transfer Restricted Securities, to register
         such Transfer Restricted Securities in such denominations and such
         names as the selling Holders may request at least two Business Days
         prior to such sale of Transfer Restricted Securities;



                 (xiv)    use their respective reasonable 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 and except as may be required solely as a
         consequence of such Seller's business (in which case the Company and
         the Guarantors will cooperate in all reasonable respects);



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



                 (xvi)    otherwise use their respective reasonable best
         efforts to comply with all applicable rules and regulations of the
         Commission, and to mail or otherwise 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 under the Act (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
         reasonable 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





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

         (d)     Restrictions on Holders.  Each Holder agrees by acquisition of
a Transfer Restricted Security that, upon receipt of (a) the notice referred to
in Section 4(c), (b) the notice referred to in Section 6(c)(iii)(C) or (c) 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 Recommencement Date.

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
securities laws; (iii) all expenses of printing (including printing
certificates for the Series B Notes to be issued in the Exchange Offer and
printing of Prospectuses), messenger and delivery services and telephone; (iv)
all fees and disbursements of counsel for the Company, the Guarantors, in
accordance with Section 7(b) below,  and the Holders of Transfer Restricted
Securities; (v) all application and filing fees in connection with listing the
Series B Notes on a national securities exchange or automated quotation system
pursuant to the requirements hereof; and (vi) all fees and disbursements of
independent certified public accountants of the Company and the Guarantors
(including the expenses of any special audit and comfort letters required by or
incident to such performance).

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

         (b)     In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company and the Guarantors
will reimburse the Initial Purchasers and the Holders of Transfer Restricted
Securities who are tendering Series A Notes in the Exchange Offer and/or
selling or reselling Series A Notes or Series B Notes pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be Andrews & Kurth
L.L.P., unless another firm shall be chosen by





                                      -14-
   16
the Holders of a majority in principal amount of the Transfer Restricted
Securities for whose benefit such Registration Statement is being prepared.
Such Holders shall be responsible for any of their other expenses incurred in
connection with the registration of the sale of their Transfer Restricted
Securities.

SECTION 8.       INDEMNIFICATION

         (a)     The Company and the Guarantors agree, jointly and severally,
to indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all
losses, claims, damages, liabilities and judgments (including without
limitation, any legal or other expenses reasonably incurred in connection with
investigating or defending any matter, including any action that could give
rise to any such losses, claims, damages, liabilities or judgments) caused by
any untrue statement or alleged untrue statement of a material fact contained
in any Registration Statement, preliminary prospectus or Prospectus (or any
amendment or supplement thereto) provided by the Company to any Holder or any
prospective purchaser of Series B Notes or registered Series A Notes, or caused
by any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by an untrue statement or omission or alleged untrue
statement or omission that is based 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, managers 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 any of the Guarantors, to the
same extent as the foregoing indemnity from the Company and the Guarantors to
such Holder set forth in Section 8(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, preliminary prospectus,
Prospectus or any amendment or supplement thereto).  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 dollar amount of the
price at which the Series A Notes purchased by it hereunder and resold to
Eligible Purchasers were offered to the Eligible Purchasers.

         (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
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





                                      -15-
   17
available to it which are different from or additional to those available to
the indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) for all indemnified parties and all such
fees and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by a majority of the Holders, in the case of the parties
indemnified pursuant to Section 8(a), and by the Company and Guarantors, in the
case of parties indemnified pursuant to Section 8(b). The indemnifying party
shall indemnify and hold harmless the indemnified party from and against any
and all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action effected with the indemnifying party's written
consent, which consent will not be unreasonably withheld.  Notwithstanding the
immediately preceding sentence, if in any case where the fees and expenses of
counsel are at the expense of the indemnifying party and an indemnified party
shall have requested the indemnifying party to reimburse the indemnified party
for such fees and expenses of counsel actually incurred by it, such
indemnifying party agrees that it shall be liable for any settlement of any
action effected without its written consent if (i) such settlement is entered
into more than 60 days after the receipt by such indemnifying party of the
aforesaid request (ii) such indemnifying party shall have received notice of
the proposed settlement being entered into at least 20 days prior to such
settlement being entered into and (iii) prior to the date of such settlement
such indemnifying party shall have failed to reimburse the indemnified party in
accordance with such request for reimbursement (or, if within 30 days of the
receipt of the aforesaid request, the indemnifying party shall have made a good
faith written challenge to the reasonableness of the amount of the
reimbursement requested or the sufficiency of the documentation supporting the
reimbursement requested (which challenge shall specifically set forth the
amount of the requested reimbursement which the indemnifying party in good
faith believes to be unreasonable or the basis for the good faith claim as to
the insufficiency of any supporting documentation), this sentence shall only
apply if such indemnifying party shall not have reimbursed the indemnified
party for the amount which is not being so challenged).  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 Holders, 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 benefits received by the Company and
the Guarantors, on the one hand and the Holders, on the other hand, shall be
deemed to be in





                                      -16-
   18
the same proportion as the total net proceeds from the offering of the Series A
Notes (after discounts and commissions, but before deducting expenses) received
by the Company, and the total proceeds received by the Holders from the sale of
Transfer Restricted Securities pursuant to a Registration Statement bear to the
total price to investors of the Series A Notes.  The relative fault of the
Company and the Guarantors, on the one hand, and of the Holders, on the other
hand, shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company or such Guarantor, on the one hand, or by the Holders, on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         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 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: (i)  no Holder (other than the Initial Purchasers), 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 dollar amount by
which the total proceeds received by such Holder from the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (A) the
amount paid by such Holder for such Transfer Restricted Securities and (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 and (ii) no Initial Purchaser shall be required to contribute any
amount in excess of the amount by which the total price at which the Series A
Notes purchased by it hereunder and resold pursuant to the Shelf Registration
Statement were offered to the public exceeds the amount of any damages which
such Initial Purchaser has otherwise been required to pay by reason of such
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(d) are several in proportion to the respective principal
amount of Transfer Restricted Securities held by each Holder hereunder and not
joint.

         (e)     The remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

SECTION 9.       RULE 144A AND RULE 144

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





                                      -17-
   19
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 the Guarantors to comply with their
respective obligations under Sections 3 and 4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Guarantor's obligations under
Sections 3 and 4 hereof.  The Company and the Guarantors further agree to waive
the defense in any action for specific performance that a remedy at law would
be adequate.

         (b)     No Inconsistent Agreements.  Neither the Company nor any
Guarantor will, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof.  Neither the Company nor any Guarantor has previously
entered into any agreement granting any registration rights with respect to its
securities to any Person, except as disclosed in the Offering Memorandum dated
June 19, 1998 with respect to the offering and sale of the Series A Notes.  The
rights granted to the Holders hereunder do not in any way conflict with and are
not inconsistent with the rights granted to the holders of the Company's and
the Guarantors' securities under any agreement in effect on the date hereof.

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

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

         (e)     Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

                 (i)      if to a Holder, at the address set forth on the

         (f)     Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent Holders; provided, that nothing herein shall be deemed
to permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement or the
Indenture.  If 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 taking and holding such Transfer 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
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (h)     Headings.  The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.





                                      -19-
   21
         (i)     Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE CONFLICT OF LAW RULES THEREOF.



         (j)     Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.



         (k)     Entire Agreement.  This Agreement is intended by the parties
as a final expression of their agreement and intended to be a complete and
exclusive statement of the agreement and understanding of the parties hereto in
respect of the subject matter contained herein.  There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to
herein with respect to the registration rights granted with respect to the
Transfer Restricted Securities.  This Agreement supersedes all prior agreements
and understandings between the parties with respect to such subject matter.
