JPMorgan Securities Inc.
Merrill Lynch, Pierce, Fenner & Smith
 Incorporated
c/o J.P. Morgan Securities Inc.
270 Park Avenue, 4th floor
New York, New York  10017

Ladies and Gentlemen:

          Mission Resources Corporation, a Delaware corporation (the "Company"),
proposes to issue and sell to J.P. Morgan Securities Inc. ("JPMorgan") and
Merrill Lynch, Pierce, Fenner & Smith Incorporated (together with JPMorgan, the
"Initial Purchasers") upon the terms and subject to the conditions set forth in
a purchase agreement dated May 23, 2001 (the "Purchase Agreement"), $125,000,000
aggregate principal amount of its 10 7/8% Senior Subordinated Notes due 2007
Series B (the "Securities") to be jointly and severally guaranteed (the
"Guarantees") by the subsidiaries of the Company listed on Schedule 1 and the
signatories hereto (collectively, the "Guarantors").  Capitalized terms used but
not defined herein shall have the meanings given to such terms in the Purchase
Agreement.

          As an inducement to the Initial Purchasers to enter into the Purchase
Agreement and in satisfaction of a condition to the obligations of the Initial
Purchasers thereunder, the Company and the Guarantors agree with the Initial
Purchasers, for the benefit of the holders (including the Initial Purchasers) of
the Securities, the Exchange Securities (as defined herein) and the Private
Exchange Securities (as defined herein) (collectively, the "Holders"), as
follows:

          1.  Registered Exchange Offer.  The Company shall (i) prepare and, not
later than 90 days following the date of original issuance of the Securities
(the "Issue Date"), file with the Commission a registration statement (the
"Exchange Offer Registration Statement") on an appropriate form under the
Securities Act with respect to a proposed offer to the Holders of the Securities
and the Guarantees (the "Exchange Offer") to issue and deliver to such Holders,
in exchange for the Securities and the Guarantees, a like aggregate principal
amount of debt securities of the Company and guarantees thereof by the
Guarantors (the "Exchange Securities") that are identical in all material
respects to the Securities, except for the transfer restrictions
<PAGE>

relating to the Securities, (ii) use its reasonable best efforts to cause the
Exchange Offer Registration Statement to become effective under the Securities
Act no later than 150 days after the Issue Date and the Exchange Offer to be
consummated no later than 180 days after the Issue Date and (iii) keep the
Exchange Offer Registration Statement effective for not less than 20 business
days (or longer, if required by applicable law) after the date on which notice
of the Exchange Offer is mailed to the Holders (such period being called the
"Exchange Offer Registration Period"). The Exchange Securities will be issued
under the Indenture or an indenture (the "Exchange Securities Indenture")
between the Company, the Guarantors and the Trustee or such other bank or trust
company that is reasonably satisfactory to the Initial Purchasers, as trustee
(the "Exchange Securities Trustee"), such indenture to be identical in all
material respects to the Indenture, except for the transfer restrictions
relating to the Securities (as described above).

          Upon the effectiveness of the Exchange Offer Registration Statement,
the Company shall promptly commence the Exchange Offer, it being the objective
of such Exchange Offer to enable each Holder electing to exchange Securities for
Exchange Securities (assuming that such Holder (a) is not an affiliate of the
Company or an Exchanging Dealer (as defined herein) not complying with the
requirements of the next sentence, (b) is not an Initial Purchaser holding
Securities that have, or that are reasonably likely to have, the status of an
unsold allotment in an initial distribution, (c) acquires the Exchange
Securities in the ordinary course of such Holder's business and (d) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Securities) and to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of
the several states of the United States.  The Company, the Guarantors, the
Initial Purchasers and each Exchanging Dealer acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the Securities
Act, each Holder that is a broker-dealer electing to exchange Securities,
acquired for its own account as a result of market-making activities or other
trading activities, for Exchange Securities (an "Exchanging Dealer"), is
required to deliver a prospectus containing substantially the information set
forth in Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of such prospectus in connection
with a sale of any such Exchange Securities received by such Exchanging Dealer
pursuant to the Exchange Offer.

          If, prior to the consummation of the Exchange Offer, any Holder holds
any Securities acquired by it that have, or that are reasonably likely to be
determined to have, the status of an unsold allotment in an initial
distribution, or any Holder is not entitled to participate in the Exchange
Offer, the Company shall, upon the request of any such Holder, simultaneously
with the delivery of the Exchange Securities in the Exchange Offer, issue and
deliver to any such Holder, in exchange for the Securities held by such Holder
(the "Private Exchange"), a like aggregate principal amount of debt securities
of the Company  and guarantees thereof by the Guarantors (the "Private Exchange
Securities") that are identical in all material respects to the Exchange
Securities, except for the transfer restrictions relating to such Private
Exchange Securities.  The Private Exchange Securities will be issued under the
same indenture as the

                                       2
<PAGE>

Exchange Securities, and the Company shall use its reasonable best efforts to
cause the Private Exchange Securities to bear the same CUSIP number as the
Exchange Securities.

          In connection with the Exchange Offer, the Company shall:

                (a) mail to each Holder a copy of the prospectus forming part of
             the Exchange Offer Registration Statement, together with an
             appropriate letter of transmittal and related documents;

                (b) keep the Exchange Offer open for not less than 20 business
             days (or longer, if required by applicable law) after the date on
             which notice of the Exchange Offer is mailed to the Holders;

                (c) utilize the services of a depositary for the Exchange Offer
             with an address in the Borough of Manhattan, The City of New York;

                (d) permit Holders to withdraw tendered Securities at any time
             prior to the close of business, New York City time, on the last
             business day on which the Exchange Offer shall remain open; and

                (e) otherwise comply in all respects with all laws that are
             applicable to the Exchange Offer.

          As soon as practicable after the close of the Exchange Offer and any
Private Exchange, as the case may be, the Company shall:

                (a) accept for exchange all Securities tendered and not validly
             withdrawn pursuant to the Exchange Offer and the Private Exchange;

                (b) deliver to the Trustee for cancellation all Securities so
             accepted for exchange; and

                (c) cause the Trustee or the Exchange Securities Trustee, as the
             case may be, promptly to authenticate and deliver to each Holder,
             Exchange Securities or Private Exchange Securities, as the case may
             be, equal in principal amount to the Securities of such Holder so
             accepted for exchange.

          The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein in order to permit such prospectus to be used by
all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Securities; provided that (i) in the case where
such prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer, such period shall be the lesser of 180 days and the date on
which all Exchanging Dealers have sold all Exchange Securities held by them and
(ii) the Company shall make such prospectus

                                       3
<PAGE>

and any amendment or supplement thereto available to any broker-dealer for use
in connection with any resale of any Exchange Securities for a period of not
less than 180 days after the consummation of the Exchange Offer.

          The Indenture or the Exchange Securities Indenture, as the case may
be, shall provide that the Securities, the Exchange Securities and the Private
Exchange Securities shall vote and consent together on all matters as one class
and that none of the Securities, the Exchange Securities or the Private Exchange
Securities will have the right to vote or consent as a separate class on any
matter.

          Interest on each Exchange Security and Private Exchange Security
issued pursuant to the Exchange Offer and in the Private Exchange will accrue
from the last interest payment date on which interest was paid on the Securities
surrendered in exchange therefor or, if no interest has been paid on the
Securities, from the Issue Date.

          Each Holder participating in the Exchange Offer shall be required to
represent to the Company that at the time of the consummation of the Exchange
Offer (i) any Exchange Securities received by such Holder will be acquired in
the ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any person to participate in the distribution of the
Securities or the Exchange Securities within the meaning of the Securities Act
and (iii) such Holder is not an affiliate of the Company or, if it is such an
affiliate, such Holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.

          Notwithstanding any other provisions hereof, the Company will ensure
that (i) any Exchange Offer Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations of the
Commission thereunder, (ii) any Exchange Offer Registration Statement and any
amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) any prospectus forming part of any Exchange Offer Registration Statement,
and any supplement to such prospectus, does not, as of the consummation of the
Exchange Offer, include an untrue statement of a material fact or omit 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.

          2.  Shelf Registration.  If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff the Company is not
permitted to effect the Exchange Offer as contemplated by Section 1 hereof, or
(ii) for any other reason the Exchange Offer is not consummated within 180 days
after the Issue Date, or (iii) any Initial Purchaser so requests with respect to
Securities or Private Exchange Securities not eligible to be exchanged for
Exchange Securities in the Exchange Offer and held by it following the
consummation of the Exchange Offer, or (iv) any applicable law or
interpretations do not permit any Holder to participate in the Exchange Offer,
or (v) any Holder that participates in the Exchange Offer does

                                       4
<PAGE>

not receive freely transferable Exchange Securities in exchange for tendered
Securities, or (vi) the Company so elects, then the following provisions shall
apply:

                (a) The Company and the Guarantors shall use their reasonable
             best efforts to file as promptly as practicable (but in no event
             more than the later of 45 days after so required or requested
             pursuant to this Section 2 or 90 days after the Issue Date) with
             the Commission (the "Shelf Filing Date"), and thereafter shall use
             their reasonable best efforts to cause to be declared effective, a
             shelf registration statement on an appropriate form under the
             Securities Act relating to the offer and sale of the Transfer
             Restricted Securities (as defined below) by the Holders thereof
             from time to time in accordance with the methods of distribution
             set forth in such registration statement (hereafter, a "Shelf
             Registration Statement" and, together with any Exchange Offer
             Registration Statement, a "Registration Statement").

                (b) The Company and the Guarantors shall use their reasonable
             best efforts to keep the Shelf Registration Statement continuously
             effective in order to permit the prospectus forming part thereof to
             be used by Holders of Transfer Restricted Securities for a period
             ending on the earlier of (i) two years from the Issue Date or such
             shorter period that will terminate when all the Transfer Restricted
             Securities covered by the Shelf Registration Statement have been
             sold pursuant thereto and (ii) the date on which the Securities
             become eligible for resale without volume restrictions pursuant to
             Rule 144 under the Securities Act (in any such case, such period
             being called the "Shelf Registration Period"). The Company and the
             Guarantors shall be deemed not to have used their reasonable best
             efforts to keep the Shelf Registration Statement effective during
             the requisite period if they voluntarily take any action that would
             result in Holders of Transfer Restricted Securities covered thereby
             not being able to offer and sell such Transfer Restricted
             Securities during that period, unless such action is required by
             applicable law.

                (c) Notwithstanding any other provisions hereof, the Company
             will ensure that (i) any Shelf Registration Statement and any
             amendment thereto and any prospectus forming part thereof and any
             supplement thereto complies in all material respects with the
             Securities Act and the rules and regulations of the Commission
             thereunder, (ii) any Shelf Registration Statement and any amendment
             thereto (in either case, other than with respect to information
             included therein in reliance upon or in conformity with written
             information furnished to the Company by or on behalf of any Holder
             specifically for use therein (the "Holders' Information")) does not
             contain an untrue statement of a material fact or omit to state a
             material fact required to be stated therein or necessary to make
             the statements therein not misleading and (iii) any prospectus
             forming part of any Shelf Registration Statement, and any
             supplement to such prospectus (in either case, other than with
             respect to Holders' Information), does not include an untrue
             statement of a material fact or omit 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.

                (d) In the absence of the events described in clauses (i)
             through (vi) of the first paragraph of this Section 2, the Company
             and the Guarantors shall not be permitted to discharge its
             obligations hereunder by means of the filing of a Shelf
             Registration Statement.

                                       5
<PAGE>

          3.  Additional Interest.  (a) The parties hereto agree that the
Holders of Transfer Restricted Securities will suffer damages if the Company and
the Guarantors fail to fulfill their obligations under Section 1 or Section 2,
as applicable, and that it would not be feasible to ascertain the extent of such
damages. Accordingly, if (i) the Exchange Offer Registration Statement is not
filed with the Commission on or prior to 90 days after the Issue Date or the
Shelf Registration Statement is not filed with the Commission on or before the
Shelf Filing Date, (ii) the Exchange Offer Registration Statement is not
declared effective within 150 days after the Issue Date or the Shelf
Registration Statement is not declared effective within 60 days of the Shelf
Filing Date, (iii) the Exchange Offer is not consummated on or prior to 180 days
after the Issue Date, or (iv) the Shelf Registration Statement is filed and
declared effective within 60 days after the Shelf Filing Date but shall
thereafter cease to be effective (at any time that the Company and the
Guarantors are obligated to maintain the effectiveness thereof) without being
succeeded within 30 days by an additional Registration Statement filed and
declared effective (each such event referred to in clauses (i) through (iv), a
"Registration Default"), the Company and the Guarantors will be jointly and
severally obligated to pay additional interest to each Holder of Transfer
Restricted Securities, during the period of one or more such Registration
Defaults, in an amount equal to $ 0.192 per week per $1,000 principal amount of
Transfer Restricted Securities held by such Holder until (i) the applicable
Registration Statement is filed, (ii) the Exchange Offer Registration Statement
is declared effective and the Exchange Offer is consummated, (iii) the Shelf
Registration Statement is declared effective or (iv) the Shelf Registration
Statement again becomes effective, as the case may be. Following the cure of all
Registration Defaults, the accrual of additional interest will cease. As used
herein, the term "Transfer Restricted Securities" means each Security or Private
Exchange Security until the earliest to occur of: (i) the date on which such
Security has been exchanged for a freely transferable Exchange Security in the
Exchange Offer, (ii) the date on which such Security or Private Exchange
Security has been effectively registered under the Securities Act and disposed
of in accordance with the Shelf Registration Statement or (iii) the date on
which such Security or Private Exchange Security is distributed to the public
pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule
144(k) under the Securities Act. Notwithstanding anything to the contrary in
this Section 3(a), neither the Company nor the Guarantors shall be required to
pay additional interest to a Holder of Transfer Restricted Securities if such
Holder failed to comply with its obligations to make the representations set
forth in the second to last paragraph of Section 1 or failed to provide the
information required to be provided by it, if any, pursuant to Section 4(n).

          (b) The Company shall notify the Trustee and the Paying Agent under
the Indenture immediately upon the happening of each and every Registration
Default. The Company and the Guarantors shall pay the additional interest due on
the Transfer Restricted Securities by depositing with the Paying Agent (which
may not be the Company for these purposes), in trust, for the benefit of the
Holders thereof, prior to 10:00 a.m., New York City time, on the next interest
payment date specified by the Indenture and the Securities, sums sufficient to
pay the additional interest then due. The additional interest due shall be
payable on each interest payment date specified by the Indenture and the
Securities to the record holder entitled to receive the interest payment to be
made on such date. Each obligation to pay

                                       6
<PAGE>

additional interest shall be deemed to accrue from and including the date of the
applicable Registration Default.

          (c) The parties hereto agree that the additional interest provided for
in this Section 3 constitute a reasonable estimate of and are intended to
constitute the sole damages that will be suffered by Holders of Transfer
Restricted Securities by reason of the failure of (i) the Shelf Registration
Statement or the Exchange Offer Registration Statement to be filed, (ii) the
Shelf Registration Statement to remain effective or (iii) the Exchange Offer
Registration Statement to be declared effective and the Exchange Offer to be
consummated, in each case to the extent required by this Agreement.

          4.  Registration Procedures.  In connection with any Registration
Statement, the following provisions shall apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to
the filing thereof with the Commission, a copy of the Registration Statement and
each amendment thereof and each supplement, if any, to the prospectus included
therein and shall use its reasonable best efforts to reflect in each such
document, when so filed with the Commission, such comments as any Initial
Purchaser may reasonably propose; (ii) include the information set forth in
Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of the prospectus forming a part
of the Exchange Offer Registration Statement, and include the information set
forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the
Exchange Offer; and (iii) if requested by any Initial Purchaser, include the
information required by Items 507 or 508 of Regulation S-K, as applicable, in
the prospectus forming a part of the Exchange Offer Registration Statement.

          (b) The Company shall advise each Initial Purchaser, each Exchanging
Dealer and the Holders (if applicable) and, if requested by any such person,
confirm such advice in writing (which advice pursuant to clauses (ii)-(v) hereof
shall be accompanied by an instruction to suspend the use of the prospectus
until the requisite changes have been made):

                (i) when any Registration Statement and any amendment thereto
             has been filed with the Commission and when such Registration
             Statement or any post-effective amendment thereto has become
             effective;

                (ii) of any request by the Commission for amendments or
             supplements to any Registration Statement or the prospectus
             included therein or for additional information;

                (iii) of the issuance by the Commission of any stop order
             suspending the effectiveness of any Registration Statement or the
             initiation of any proceedings for that purpose;

                                       7
<PAGE>

                (iv) of the receipt by the Company of any notification with
             respect to the suspension of the qualification of the Securities,
             the Exchange Securities or the Private Exchange Securities for sale
             in any jurisdiction or the initiation or threatening of any
             proceeding for such purpose; and

                (v) of the happening of any event that requires the making of
             any changes in any Registration Statement or the prospectus
             included therein in order that the statements therein are not
             misleading and do not omit to state a material fact required to be
             stated therein or necessary to make the statements therein not
             misleading.

          (c) The Company and the Guarantors will make every reasonable effort
to obtain the withdrawal at the earliest practicable time of any order
suspending the effectiveness of any Registration Statement.

          (d) The Company will furnish to each Holder of Transfer Restricted
Securities included within the coverage of any Shelf Registration Statement,
without charge, at least one conformed copy of such Shelf Registration Statement
and any post-effective amendment thereto, including financial statements and
schedules and, if any such Holder so requests in writing, all exhibits thereto
(including those, if any, incorporated by reference).

          (e) The Company will, during the Shelf Registration Period, promptly
deliver to each Holder of Transfer Restricted Securities included within the
coverage of any Shelf Registration Statement, without charge, as many copies of
the prospectus (including each preliminary prospectus) included in such Shelf
Registration Statement and any amendment or supplement thereto as such Holder
may reasonably request; and the Company consents to the use of such prospectus
or any amendment or supplement thereto by each of the selling Holders of
Transfer Restricted Securities in connection with the offer and sale of the
Transfer Restricted Securities covered by such prospectus or any amendment or
supplement thereto.

          (f) The Company will furnish to each Initial Purchaser and each
Exchanging Dealer, and to any other Holder who so requests, without charge, at
least one conformed copy of the Exchange Offer Registration Statement and any
post-effective amendment thereto, including financial statements and schedules
and, if any Initial Purchaser or Exchanging Dealer or any such Holder so
requests in writing, all exhibits thereto (including those, if any, incorporated
by reference).

          (g) The Company will, during the Exchange Offer Registration Period or
the Shelf Registration Period, as applicable, promptly deliver to each Initial
Purchaser, each Exchanging Dealer and such other persons that are required to
deliver a prospectus following the Exchange Offer, without charge, as many
copies of the final prospectus included in the Exchange Offer Registration
Statement or the Shelf Registration Statement and any amendment or supplement
thereto as such Initial Purchaser, Exchanging Dealer or other persons may
reasonably request; and the Company and the Guarantors consent to the use of
such prospectus or any amendment or supplement thereto by any such Initial
Purchaser, Exchanging Dealer or other persons, as applicable, as aforesaid.

                                       8
<PAGE>

          (h) Prior to the effective date of any Registration Statement, the
Company and the Guarantors will use their reasonable best efforts to register or
qualify, or cooperate with the Holders of Securities, Exchange Securities or
Private Exchange Securities included therein and their respective counsel in
connection with the registration or qualification of, such Securities, Exchange
Securities or Private Exchange Securities for offer and sale under the
securities or blue sky laws of such jurisdictions as any such Holder reasonably
requests in writing and do any and all other acts or things necessary or
advisable to enable the offer and sale in such jurisdictions of the Securities,
Exchange Securities or Private Exchange Securities covered by such Registration
Statement; provided that the Company and the Guarantors will not be required to
qualify generally to do business in any jurisdiction where it is not then so
qualified or to take any action which would subject it to general service of
process or to taxation in any such jurisdiction where it is not then so subject.

          (i) The Company and the Guarantors will cooperate with the Holders of
Securities, Exchange Securities or Private Exchange Securities to facilitate the
timely preparation and delivery of certificates representing Securities,
Exchange Securities or Private Exchange Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations
and registered in such names as the Holders thereof may request in writing prior
to sales of Securities, Exchange Securities or Private Exchange Securities
pursuant to such Registration Statement.

          (j) If any event contemplated by Section 4(b)(ii) through (v) occurs
during the period for which the Company and the Guarantors are required to
maintain an effective Registration Statement, the Company will promptly prepare
and file with the Commission a post-effective amendment to the Registration
Statement or a supplement to the related prospectus or file any other required
document so that, as thereafter delivered to purchasers of the Securities,
Exchange Securities or Private Exchange Securities from a Holder, the prospectus
will not include an untrue statement of a material fact or omit 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.

          (k) Not later than the effective date of the applicable Registration
Statement, the Company will provide a CUSIP number for the Securities, the
Exchange Securities and the Private Exchange Securities, as the case may be, and
provide the applicable trustee with printed certificates for the Securities, the
Exchange Securities or the Private Exchange Securities, as the case may be, in a
form eligible for deposit with The Depository Trust Company.

          (l) The Company and the Guarantors will comply with all applicable
rules and regulations of the Commission and will make generally available to its
security holders as soon as practicable after the effective date of the
applicable Registration Statement an earning statement satisfying the provisions
of Section 11(a) of the Securities Act; provided that in no event shall such
earning statement be delivered later than 45 days after the end of a 12-month
period (or 90 days, if such period is a fiscal year) beginning with the first
month of the

                                       9
<PAGE>

Company's first fiscal quarter commencing after the effective date of the
applicable Registration Statement, which statement shall cover such 12-month
period.

          (m) The Company and the Guarantors will cause the Indenture or the
Exchange Securities Indenture, as the case may be, to be qualified under the
Trust Indenture Act as required by applicable law in a timely manner.

          (n) The Company may require each Holder of Transfer Restricted
Securities to be registered pursuant to any Shelf Registration Statement to
furnish to the Company such information concerning the Holder and the
distribution of such Transfer Restricted Securities as the Company may from time
to time reasonably require for inclusion in such Shelf Registration Statement,
and the Company may exclude from such registration the Transfer Restricted
Securities of any Holder that fails to furnish such information within a
reasonable time after receiving such request.

          (o) In the case of a Shelf Registration Statement, each Holder of
Transfer Restricted Securities to be registered pursuant thereto agrees by
acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company pursuant to Section 4(b)(ii) through (v), such Holder
will discontinue disposition of such Transfer Restricted Securities until such
Holder's receipt of copies of the supplemental or amended prospectus
contemplated by Section 4(j) or until advised in writing (the "Advice") by the
Company that the use of the applicable prospectus may be resumed. If the Company
shall give any notice under Section 4(b)(ii) through (v) during the period that
the Company is required to maintain an effective Registration Statement (the
"Effectiveness Period"), such Effectiveness Period shall be extended by the
number of days during such period from and including the date of the giving of
such notice to and including the date when each seller of Transfer Restricted
Securities covered by such Registration Statement shall have received (x) the
copies of the supplemental or amended prospectus contemplated by Section 4(j)
(if an amended or supplemental prospectus is required) or (y) the Advice (if no
amended or supplemental prospectus is required).

          (p) In the case of a Shelf Registration Statement, the Company and the
Guarantors shall enter into such customary agreements (including, if requested,
an underwriting agreement in customary form) and take all such other action, if
any, as Holders of a majority in aggregate principal amount of the Securities,
Exchange Securities and Private Exchange Securities being sold or the managing
underwriters (if any) shall reasonably request in order to facilitate any
disposition of Securities, Exchange Securities or Private Exchange Securities
pursuant to such Shelf Registration Statement.

          (q) In the case of a Shelf Registration Statement, the Company shall
(i) make reasonably available for inspection by a representative of, and Special
Counsel (as defined below) acting for, Holders of a majority in aggregate
principal amount of the Securities, Exchange Securities and Private Exchange
Securities being sold and any underwriter participating in any disposition of
Securities, Exchange Securities or Private Exchange Securities pursuant to such
Shelf Registration Statement, all relevant financial and other records,
pertinent

                                       10
<PAGE>

corporate documents and properties of the Company and its subsidiaries and (ii)
use its reasonable best efforts to have its officers, directors, employees,
accountants and counsel supply all relevant information reasonably requested by
such representative, Special Counsel or any such underwriter (an "Inspector") in
connection with such Shelf Registration Statement.

          (r) In the case of a Shelf Registration Statement, the Company shall,
if requested by Holders of a majority in aggregate principal amount of the
Securities, Exchange Securities and Private Exchange Securities being sold,
their Special Counsel or the managing underwriters (if any) in connection with
such Shelf Registration Statement, use its reasonable best efforts to cause (i)
its counsel to deliver an opinion relating to the Shelf Registration Statement
and the Securities, Exchange Securities or Private Exchange Securities, as
applicable, in customary form, (ii) its officers to execute and deliver all
customary documents and certificates requested by Holders of a majority in
aggregate principal amount of the Securities, Exchange Securities and Private
Exchange Securities being sold, their Special Counsel or the managing
underwriters (if any) and (iii) its independent public accountants to provide a
comfort letter or letters in customary form, subject to receipt of appropriate
documentation as contemplated, and only if permitted, by Statement of Auditing
Standards No. 72.

          5.  Registration Expenses.  The Company and the Guarantors will bear
all expenses incurred in connection with the performance of its obligations
under Sections 1, 2, 3 and 4 and the Company will reimburse the Initial
Purchasers and the Holders for the reasonable fees and disbursements of one firm
of attorneys (in addition to any local counsel) chosen by the Holders of a
majority in aggregate principal amount of the Securities, the Exchange
Securities and the Private Exchange Securities to be sold pursuant to each
Registration Statement (the "Special Counsel") acting for the Initial Purchasers
or Holders in connection therewith.

          6.  Indemnification.  (a) In the event of a Shelf Registration
Statement or in connection with any prospectus delivery pursuant to an Exchange
Offer Registration Statement by an Initial Purchaser or Exchanging Dealer, as
applicable, the Company and each of the Guarantors shall jointly and severally
indemnify and hold harmless each Holder (including, without limitation, any such
Initial Purchaser or Exchanging Dealer), its affiliates, their respective
officers, directors, employees, representatives and agents, and each person, if
any, who controls such Holder within the meaning of the Securities Act or the
Exchange Act (collectively referred to for purposes of this Section 6 and
Section 7 as a Holder) from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof (including, without
limitation, any loss, claim, damage, liability or action relating to purchases
and sales of Securities, Exchange Securities or Private Exchange Securities), to
which that Holder may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any such Registration
Statement or any prospectus forming part thereof or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under

                                       11
<PAGE>

which they were made, not misleading, and shall reimburse each Holder promptly
upon demand for any legal or other expenses reasonably incurred by that Holder
in connection with investigating or defending or preparing to defend against or
appearing as a third party witness in connection with any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Guarantors shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, an untrue statement or alleged untrue statement in or omission or
alleged omission from any of such documents in reliance upon and in conformity
with any Holders' Information; and provided, further, that with respect to any
such untrue statement in or omission from any related preliminary prospectus,
the indemnity agreement contained in this Section 6(a) shall not inure to the
benefit of any Holder from whom the person asserting any such loss, claim,
damage, liability or action received Securities, Exchange Securities or Private
Exchange Securities to the extent that such loss, claim, damage, liability or
action of or with respect to such Holder results from the fact that both (A) a
copy of the final prospectus and any amendment or supplement thereto was not
sent or given to such person at or prior to the written confirmation of the sale
of such Securities, Exchange Securities or Private Exchange Securities to such
person and (B) the untrue statement in or omission from the related preliminary
prospectus was corrected in the final prospectus or any amendment or supplement
thereto unless, in either case, such failure to deliver the final prospectus or
any amendment or supplement thereto was a result of non-compliance by the
Company with Section 4(d), 4(e), 4(f) or 4(g).

          (b) In the event of a Shelf Registration Statement, each Holder shall
indemnify and hold harmless the Company, each Guarantor and their respective
affiliates, their respective officers, directors, employees, representatives and
agents, and each person, if any, who controls the Company or any Guarantor
within the meaning of the Securities Act or the Exchange Act (collectively
referred to for purposes of this Section 6(b) and Section 7 as the Company),
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof, to which the Company may become subject, whether
commenced or threatened, under the Securities Act, the Exchange Act, any other
federal or state statutory law or regulation, at common law or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any such Registration Statement or any prospectus forming part
thereof or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, but in each case only
to the extent that the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with any
Holders' Information furnished to the Company by such Holder, and shall
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending or preparing to defend
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that no such Holder shall be liable for any indemnity claims hereunder
in excess of the amount of net proceeds received by such Holder from the sale of
Securities, Exchange Securities or Private Exchange Securities pursuant to such
Shelf Registration Statement.

                                       12
<PAGE>

          (c) Promptly after receipt by an indemnified party under this Section
6 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
however, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced by such failure; and provided, further,
that the failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 6. If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 6 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than the reasonable costs of investigation;
provided, however, that an indemnified party shall have the right to employ its
own counsel in any such action, but the fees, expenses and other charges of such
counsel for the indemnified party will be at the expense of such indemnified
party unless (1) the employment of counsel by the indemnified party has been
authorized in writing by the indemnifying party, (2) the indemnified party has
reasonably concluded (based upon written advice of counsel to the indemnified
party) that there may be legal defenses available to it or other indemnified
parties that are different from or in addition to those available to the
indemnifying party, (3) a conflict or potential conflict exists (based upon
written advice of counsel to the indemnified party) between the indemnified
party and the indemnifying party (in which case the indemnifying party will not
have the right to direct the defense of such action on behalf of the indemnified
party) or (4) the indemnifying party has not in fact employed counsel reasonably
satisfactory to the indemnified party to assume the defense of such action
within a reasonable time after receiving notice of the commencement of the
action, in each of which cases the reasonable fees, disbursements and other
charges of counsel will be at the expense of the indemnifying party or parties.
It is understood that the indemnifying party or parties shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees, disbursements and other charges of more than one
separate firm of attorneys (in addition to any local counsel) at any one time
for all such indemnified party or parties. Each indemnified party, as a
condition of the indemnity agreements contained in Sections 6(a) and 6(b), shall
use all reasonable efforts to cooperate with the indemnifying party in the
defense of any such action or claim. No indemnifying party shall be liable for
any settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action,
the indemnifying party agrees to indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment. No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been

                                       13
<PAGE>

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

          7.  Contribution.  If the indemnification provided for in Section 6 is
unavailable or insufficient to hold harmless an indemnified party under Section
6(a) or 6(b), then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering and sale
of the Securities, on the one hand, and a Holder with respect to the sale by
such Holder of Securities, Exchange Securities or Private Exchange Securities,
on the other, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and each of the Guarantors on the one hand and such Holder
on the other with respect to the statements or omissions that resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and each of the Guarantors on the one hand and a Holder on the other
with respect to such offering and such sale shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Securities (before
deducting expenses) received by or on behalf of the Company and each of the
Guarantors, on the one hand, and the total discounts and commissions received by
such Holder with respect to the Securities, Exchange Securities or Private
Exchange Securities, on the other, bear to the total gross proceeds from the
sale of Securities, Exchange Securities or Private Exchange Securities. The
relative fault 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 the Company and each of the
Guarantors or information supplied by the Company and each of the Guarantors on
the one hand or to any Holders' Information supplied by such Holder on the
other, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 7 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 7 shall be deemed
to include, for purposes of this Section 7, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending or preparing to defend any such action or claim. Notwithstanding
the provisions of this Section 7, an indemnifying party that is a Holder of
Securities, Exchange Securities or Private Exchange Securities shall not be
required to contribute any amount in excess of the amount by which the total
price at which the Securities, Exchange Securities or Private Exchange
Securities sold by such indemnifying party to any purchaser exceeds the amount
of any damages which such indemnifying party has otherwise paid or become liable
to pay by reason of any untrue or alleged untrue statement or omission or
alleged omission.

                                       14
<PAGE>

No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          8.  Rules 144 and 144A.  The Company shall use its reasonable best
efforts to file the reports required to be filed by it under the Securities Act
and the Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the written request of any Holder
of Transfer Restricted Securities, make publicly available other information so
long as necessary to permit sales of such Holder's securities pursuant to Rules
144 and 144A. The Company and the Guarantors covenant that they will take such
further action as any Holder of Transfer Restricted Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Transfer Restricted Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rules 144 and 144A
(including, without limitation, the requirements of Rule 144A(d)(4)). Upon the
written request of any Holder of Transfer Restricted Securities, the Company and
the Guarantors shall deliver to such Holder a written statement as to whether it
has complied with such requirements. Notwithstanding the foregoing, nothing in
this Section 8 shall be deemed to require the Company to register any of its
securities pursuant to the Exchange Act.

          9.  Underwritten Registrations.  If any of the Transfer Restricted
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority in aggregate principal amount of such Transfer Restricted Securities
included in such offering, subject to the consent of the Company (which shall
not be unreasonably withheld or delayed), and such Holders shall be responsible
for all underwriting commissions and discounts in connection therewith.

          No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

          10. Exchange of Existing 10 7/8% Senior Subordinated Notes.
Notwithstanding any other provision of this Agreement, the Company may register
the exchange of the 10 7/8% Senior Subordinated Notes due 2007 that the Company
issued under the Indenture (as amended to the date hereof) dated as of April 9,
1997 (the "1997 Notes"), in the Exchange Offer Registration Statement filed
hereunder; provided that the securities issued in exchange for such securities
and the Exchange Securities must be issued under the same indenture (whether the
Indenture or the Exchange Securities Indenture). If the 1997 Notes are covered
by the Exchange Offer Registration Statement pursuant to this Section 10, the
terms "Exchange Offer" shall include the offer to exchange the 1997 Notes.

                                       15
<PAGE>

          11.  Miscellaneous.  (a) Amendments and Waivers. The provisions of
this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities, taken as a single class. Notwithstanding the foregoing, a
waiver or consent to depart from the provisions hereof with respect to a matter
that relates exclusively to the rights of Holders whose Securities, Exchange
Securities or Private Exchange Securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities being sold by such Holders pursuant to such Registration
Statement.

          (b) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telecopier or air courier guaranteeing next-day delivery:

                (1) if to a Holder, at the most current address given by such
             Holder to the Company in accordance with the provisions of this
             Section 10(b), which address initially is, with respect to each
             Holder, the address of such Holder maintained by the Registrar
             under the Indenture, with a copy in like manner to J. P. Morgan
             Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith
             Incorporated;

                (2) if to an Initial Purchaser, initially at its address set
             forth in the Purchase Agreement;

                (3) if to the Company, initially at the address of the Company
             set forth in the Purchase Agreement; and

                (4) if to the Guarantors, initially at the address of the
             Guarantors set forth in the Purchase Agreement.

          All such notices and communications shall be deemed to have been duly
given: when delivered by hand, if personally delivered; one business day after
being delivered to a next-day air courier; five business days after being
deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

          (c) Successors And Assigns. This Agreement shall be binding upon the
Company, the Guarantors and their respective successors and assigns.

          (d) Counterparts. This Agreement may be executed in any number of
counterparts (which may be delivered in original form or by telecopier) 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.

                                       16
<PAGE>

          (e) Definition of Terms. For purposes of this Agreement, (a) the term
"business day" means any day on which the New York Stock Exchange, Inc. is open
for trading, (b) the term "subsidiary" has the meaning set forth in Rule 405
under the Securities Act and (c) except where otherwise expressly provided, the
term "affiliate" has the meaning set forth in Rule 405 under the Securities Act.

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

          (g) Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

          (h) Remedies. In the event of a breach by the Company or any of the
Guarantors or by any Holder of any of their respective obligations under this
Agreement, each Holder or the Company or any Guarantor, as the case may be, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages (other than the recovery of damages for a breach by the
Company or any Guarantor of their obligations under Sections 1 or 2 hereof for
which additional interest has been paid pursuant to Section 3 hereof), will be
entitled to specific performance of its rights under this Agreement. The
Company, each Guarantor and each Holder agree that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agree that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

          (i) No Inconsistent Agreements. Each of the Company and each Guarantor
represents, warrants and agrees that (i) it has not entered into, shall not, on
or after the date of this Agreement, enter into any agreement that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof, (ii) it has not previously
entered into any agreement which remains in effect granting any registration
rights with respect to any of its debt securities to any person and (iii)
without limiting the generality of the foregoing, without the written consent of
the Holders of a majority in aggregate principal amount of the then outstanding
Transfer Restricted Securities, it shall not grant to any person the right to
request the Company to register any debt securities of the Company under the
Securities Act unless the rights so granted are not in conflict or inconsistent
with the provisions of this Agreement.

          (j) No Piggyback on Registrations. Neither the Company nor the
Guarantors nor any of its security holders (other than the Holders of Transfer
Restricted Securities in such capacity) shall have the right to include any
securities of the Company in any Shelf Registration or Exchange Offer other than
Transfer Restricted Securities.

          (k) Severability. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein

                                       17
<PAGE>

shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their reasonable best efforts
to find and employ an alternative means to achieve the same or substantially the
same result as that contemplated by such term, provision, covenant or
restriction. It is hereby stipulated and declared to be the intention of the
parties that they would have executed the remaining terms, provisions, covenants
and restrictions without including any of such that may be hereafter declared
invalid, illegal, void or unenforceable.

                                       18

          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Securities where such Securities were acquired by such broker-dealer as a result
of market-making activities or other trading activities.  The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale.  See "Plan of Distribution."

          Each broker-dealer that receives Exchange Securities for its own
account in exchange for Securities, where such Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities.  See "Plan of Distribution".

                              PLAN OF DISTRIBUTION

          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities.  The Company has agreed
that, for a period of 180 days after the Expiration Date, it will make this
prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale.  In addition, until _______________, 200_,
all dealers effecting transactions in the Exchange Securities may be required to
deliver a prospectus.

          The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers.  Exchange Securities received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or at negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities.  Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act.  The Letter of Transmittal states that,
by acknowledging that it will deliver and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

          For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any broker-
dealers and will indemnify the Holders of the Securities (including any broker-
dealers) against certain liabilities, including liabilities under the Securities
Act.
