Dear
Sirs: 

        Universal
Compression, Inc, a Texas corporation (the "Company"), proposes to issue and sell to you (the "Initial
Purchasers"), upon the terms set forth in a purchase agreement dated May 21, 2003 (the "Purchase Agreement"),
$175,000,000 aggregate principal amount of its 71/4% Senior Notes due 2010 (the "Initial Notes"). The Initial Notes will be issued
pursuant to an Indenture, to be dated as of the date hereof (the "Indenture"), between the Company and The Bank of New York, as trustee (the
"Trustee"). To satisfy a condition to the obligations of the Initial Purchasers under the Purchase Agreement, the Company agrees with the Initial
Purchasers, for the benefit of the Initial Purchasers and the subsequent holders of the Notes (as defined below) (collectively the "Holders"), as
follows: 

        1.    Registered Exchange Offer.    Unless not permitted by applicable law (after the Company has complied with the
ultimate paragraph of this Section 1), the Company shall prepare and, not later than 90 days (such 90th day being a "Filing Deadline")
after the date on which the Initial Purchasers purchase the Initial Notes pursuant to the Purchase Agreement (the "Closing Date"), file with the
Securities and Exchange Commission (the "Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended (the "Securities Act"), with respect to a
proposed offer (the "Registered Exchange Offer") to the Holders of Transfer Restricted Notes (as defined in Section 6 hereof), who are not
prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial Notes, a like aggregate
principal amount of debt securities of the Company issued under the Indenture, identical in all material respects to the Initial Notes and registered under the Securities Act (the
"Exchange Notes"). The Company shall (i) use its commercially reasonable best efforts to cause such Exchange Offer Registration Statement to be
declared effective under the Securities Act within 180 days after the Closing Date (such 180th day being an "Effectiveness Deadline");
(ii) promptly following the effectiveness of the Exchange Offer Registration Statement, offer the Exchange Notes in exchange for surrender of the Initial Notes; and (iii) use its
commercially reasonable best efforts to keep the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered
Exchange Offer is mailed to the Holders (such period being called the "Exchange Offer Registration Period"). 

        When
the Company commences the Registered Exchange Offer, the Company (i) will be entitled to consummate the Registered Exchange Offer 30 days after such commencement
(provided that the Company has accepted all the Initial Notes theretofore validly tendered in accordance with the terms of the Registered Exchange Offer) and (ii) will be required to consummate
the Registered Exchange Offer on or before the 60th business day after the date on which the Exchange Offer Registration Statement is declared effective (the "Consummation
Deadline"). 

        Following
the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of
such Registered Exchange Offer to enable each Holder of Transfer Restricted Notes electing to exchange the Initial Notes for Exchange Notes (assuming that such Holder is not an affiliate of the
Company within the meaning of the Securities Act, 

 

acquires
the Exchange Notes in the ordinary course of such Holder's business and has no arrangements with any person to participate in the distribution of the Exchange Notes and is not prohibited by
any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Notes 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 acknowledges that, pursuant to current interpretations by the Commission's staff of Section 5 of the Securities Act, in the absence of an applicable exemption
therefrom, (i) each Holder which is a broker-dealer electing to exchange Initial Notes, acquired for its own account as a result of market making activities
or other trading activities, for Exchange Notes (an "Exchanging Dealer"), is required to deliver a prospectus containing the information set forth in
(a) Annex A hereto on the cover, (b) Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer" section, and (c) Annex C hereto in the "Plan
of Distribution" section of such prospectus in connection with a sale of any such Exchange Notes received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial
Purchaser that elects to sell Notes (as defined below) acquired in exchange for Initial Notes constituting any portion of an unsold allotment, is required to deliver a prospectus containing the
information required by Item 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 

        The
Company shall use its commercially 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 lawfully delivered 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 Notes; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Notes held
by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto available to any broker-
dealer for use in connection with any resale of any Exchange Notes for a period of not less than 180-days after the consummation of the Registered Exchange Offer. 

        If,
upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial Notes acquired by it as part of its initial distribution, the Company, simultaneously with the
delivery of the Exchange Notes pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange (the
"Private Exchange") for the Initial Notes held by such Initial Purchaser, a like principal amount of debt securities of the Company issued under the
Indenture and identical in all material respects to the Initial Notes (the "Private Exchange Notes"). The Initial Notes, the Exchange Notes and the
Private Exchange Notes are herein collectively called the "Notes." 

        In
connection with the Registered 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; 

        (b)   keep
the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice thereof is mailed to the
Holders; 

        (c)   utilize
the services of a depositary for the Registered Exchange Offer, which may be the Trustee or an affiliate of the Trustee; 

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

        (e)   otherwise
comply with all applicable laws. 

2

 

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

        (x)   accept
for exchange all the Notes validly tendered and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange; and 

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

        The
Indenture will provide that the Exchange Notes will not be subject to the transfer restrictions set forth in the Indenture and that all the Notes will vote and consent together on
all matters as one class and that none of the Notes will have the right to vote or consent as a class separate from one another on any matter. 

        Interest
on each Exchange Note and Private Exchange Note issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on
which interest was paid on the Initial Notes surrendered in exchange therefor or, if no interest has been paid on the Initial Notes, from the date of original issue of the Initial Notes. 

        Each
Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the commencement of the Registered Exchange Offer
(i) any Exchange Notes received by such Holder will be acquired in the ordinary course of business, (ii) such Holder has no arrangements or understanding with any person to participate
in the distribution of the Initial Notes or the Exchange Notes within the meaning of the Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule 405 of the Securities
Act, of the Company or if it is an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such
Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Notes and (v) if such Holder is a broker-dealer, that it will
receive Exchange Notes for its own account in exchange for Initial Notes that were acquired as a result of market-making activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. 

        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 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 include an untrue statement of a
material fact or omit to state 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. 

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

        2.    Shelf Registration.    If, (i) because of any change in law or in applicable interpretations thereof by
the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not
consummated by the 240th day after the Closing Date, (iii) any Initial Purchaser so requests with respect to the Initial Notes (or the Private Exchange Notes) not 

3

 

eligible
to be exchanged for Exchange Notes in the Registered Exchange Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging
Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder
does not receive freely tradeable Exchange Notes on the date of the exchange and any such Holder so requests, the Company shall take the following actions (the date on which any of the conditions
described in the foregoing clauses (i) through (iv) occur, including in the case of clause (iii) or (iv) the receipt of the required notice, being a
"Trigger Date"): 

        (a)   The
Company shall promptly (but in no event more than 60 days after the Trigger Date (such 60th day being a "Shelf Filing
Deadline")) use its commercially reasonable best efforts to file with the Commission and thereafter cause to be declared effective (x) in the case of clause (i)
above, no later than 180 days after the Closing Date and (y) otherwise no later than 60 days after the Shelf Filing Deadline (such 180th day or 60th day being an
"Effectiveness Deadline") a registration statement (the "Shelf Registration Statement" and, together
with the Exchange Offer Registration Statement, a "Registration Statement") on an appropriate form under the Securities Act relating to the offer and
sale of the Transfer Restricted Notes (as defined in Section 6(d)) by the Holders thereof from time to time in accordance with the methods of distribution set
forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the "Shelf Registration"); provided, however, that
no Holder (other than an Initial Purchaser) shall be entitled to have the Notes held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the
provisions of this Agreement applicable to such Holder. 

        (b)   The
Company shall use its commercially reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included
therein to be lawfully delivered by the Holders of the relevant Notes, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the date of its
effectiveness or such shorter period that will terminate when all the Notes covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) are no longer subject
to restrictions on resale pursuant to Rule 144 under the Securities Act, or any successor rule thereof. 

        (c)   Notwithstanding
any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any
amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements
of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. 

        3.    Registration Procedures.    In connection with any Shelf Registration contemplated by Section 2 hereof
and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, 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, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is
participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its reasonable best efforts to reflect in each such document, when so filed with the
Commission, such comments as such Initial Purchaser reasonably may 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 Registered Exchange Offer; (iii) if requested by an Initial Purchaser,
include the information required by Item 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a part of the Exchange Offer Registration
Statement; (iv) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution," 

4

 

reasonably
acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential
"underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) of Exchange Notes received by such broker-dealer in the Registered Exchange Offer (a "Participating
Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of
the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf
Registration Statement, include the names of the Holders who propose to sell Notes pursuant to the Shelf Registration Statement as selling securityholders. 

        (b)   The
Company shall give written notice to the Initial Purchasers, the Holders of the Notes and any Participating Broker-Dealer from whom the Company has received prior
written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice 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
the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective
amendment thereto has become effective; 

        (ii)   of
any request by the Commission for amendments or supplements to the 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 the Registration Statement or the initiation of any proceedings for that purpose; 

        (iv)  of
the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Notes 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 Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the
prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the
prospectus, in light of the circumstances under which they were made) not misleading. 

        (c)   The
Company shall make every commercially reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the
Registration Statement. 

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

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

        (f)    The
Company shall, during the Shelf Registration Period, deliver to each Holder of Notes included within the coverage of the Shelf Registration, without charge, as many
copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company
consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Notes in connection with the offering
and sale of the Notes covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

5

 

        (g)   The
Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating Broker-Dealer and such other persons required to deliver a prospectus
following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such
persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if
necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and
sale of the Exchange Notes covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer Registration Statement. 

        (h)   Prior
to any public offering of the Notes pursuant to any Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Notes
included therein and their respective counsel in connection with the registration or qualification of the Notes for offer and sale under the securities or "blue sky" laws of such states of the United
States as any Holder of the Notes 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 Notes covered
by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or
(ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 

        (i)    The
Company shall cooperate with the Holders of the Notes to facilitate the timely preparation and delivery of certificates representing the Notes to be sold pursuant to
any Registration Statement free of any restrictive legends. 

        (j)    Upon
the occurrence of any event contemplated by paragraphs (ii) through (v) of Section 3(b) above during the period for which the Company is
required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the
related prospectus and any other required document so that, as thereafter delivered to Holders of the Notes or purchasers of Notes, the prospectus will not contain an untrue statement of a material
fact or omit to state any 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. If the
Company notifies the Initial Purchasers, the Holders of the Notes and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to
suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers, the Holders of the Notes and any such Participating Broker-Dealers shall
suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for
in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of
the Notes and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j). 

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

        (l)    The
Company will comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf
Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act, no 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 Company's first fiscal quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period. 

6

 

        (m)  The
Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall
be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder
pursuant to the applicable provisions of the Indenture. 

        (n)   The
Company may require each Holder of Notes to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and
the distribution of the Notes as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, including requiring the Holder to properly complete and execute
such selling Note Holder notice and questionnaires, and any amendments or supplements thereto, as the Company may reasonably deem necessary or appropriate, and the Company may exclude from such
registration the Notes of any Holder that fails to furnish such information within a reasonable time after receiving such request. 

        (o)   The
Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as
any Holder of the Notes shall reasonably request in order to facilitate the disposition of the Notes pursuant to any Shelf Registration. 

        (p)   In
the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the Holders of the Notes, any underwriter participating
in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Notes or any such underwriter all relevant financial and
other records, pertinent corporate documents and properties of the Company and (ii) cause the Company's officers, directors, employees, accountants and auditors to supply all relevant
information reasonably requested by the Holders of the Notes or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be
reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and
information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described
in Section 4 hereof. 

        (q)   In
the case of any Shelf Registration, the Company, if requested by any Holder of Notes covered thereby, shall cause (i) its counsel to deliver an opinion and
updates thereof relating to the Notes in customary form addressed to such Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date of
such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include the existence and good standing of the Company; the due authorization, execution and
delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of the
applicable Notes; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Notes, or any agreement of
the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the
requirements of the Securities Act and the Trust Indenture Act, respectively; and, as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent
post-effective amendment thereto, as the case may be, the absence from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any
documents incorporated by reference therein of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act);
(ii) its officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable Notes and (iii) its independent
public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the selling
Holders of the applicable Notes and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary
underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72. 

7

 

        (r)   In
the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its
counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Exhibit C to the Purchase Agreement with such changes as are customary
in connection with the preparation of a Registration Statement and (ii) its independent public accountants and the independent public accountants with respect to any other entity for which
financial information is provided in the Registration Statement to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements
as to the substance thereof as set forth in Section 7(e) of the Purchase Agreement, with appropriate date changes. 

8

  

        (s)   If
a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Notes by Holders to the Company (or to such other Person as
directed by the Company) in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, the Company shall mark, or caused to be marked, on the Initial Notes so exchanged that
such Initial Notes are being canceled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall the Initial Notes be marked as paid or otherwise
satisfied. 

        (t)    The
Company will use its reasonable best efforts to (a) if the Initial Notes have been rated prior to the initial sale of such Initial Notes, confirm such ratings
will apply to the Notes covered by a Registration Statement, or (b) if the Initial Notes were not previously rated, cause the Notes covered by a Registration Statement to be rated with the
appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Notes covered by such Registration Statement, or by the managing underwriters, if any. 

        (u)   In
the event that any broker-dealer registered under the Exchange Act shall underwrite any Notes or participate as a member of an underwriting syndicate or selling group
or "assist in the distribution" (within the meaning of the Conduct Rules (the "Rules") of the National Association of Securities Dealers, Inc.
("NASD")) thereof, whether as a Holder of such Notes or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or
otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including Rule 2720, shall so
require, engaging a "qualified independent underwriter" (as defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Notes, to exercise usual
standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent,
to recommend the yield of such Notes, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and
(iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 

        (v)   The
Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Notes covered by a Registration Statement
contemplated hereby. 

        4.    Registration Expenses.    

        (a)   All
expenses incident to the Company's performance of and compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement is
ever filed or 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 of Prospectuses), messenger and delivery services and telephone; 

        (iv)  all
fees and disbursements of counsel for the Company; and 

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

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

        (b)   In
connection with any Registration Statement required by this Agreement, the Company will reimburse the Initial Purchasers and the Holders of Transfer Restricted Notes
who are tendering Initial Notes in the Registered Exchange Offer and/or selling or reselling Notes pursuant to the "Plan of 

9

 

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 Vinson & Elkins L.L.P. unless another firm shall be chosen by the Holders of a majority in principal amount of the Transfer Restricted Notes for whose benefit such Registration
Statement is being prepared. 

        5.    Indemnification.    

        (a)   The
Company agrees to indemnify and hold harmless each Holder of the Notes, any Participating Broker-Dealer and each person, if any, who controls such Holder or such
Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any Participating Broker-Dealer and such controlling persons are referred to collectively as the
"Indemnified Parties") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but
not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Notes) to which each Indemnified Party may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as
such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other
expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company
shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged
omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance upon and in conformity
with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement
or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall
not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Notes concerned, to the extent that a
prospectus relating to such Notes was required to be delivered by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage
or liability of such Holder or Participating Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Notes to
such person, a copy of the final prospectus if the Company had previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity
agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each
person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders of the Notes
if requested by such Holders. 

        (b)   Each
Holder of the Notes, severally and not jointly, will indemnify and hold harmless the Company and its officers and employees, each of its directors, and each person,
if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which
the Company or any such director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages,
liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or
supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to
make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in
conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, 

10

 

shall
reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with
investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the
Company or any such director, officer, employee or controlling person. 

        (c)   Promptly
after receipt by an indemnified party under this Section 5 of notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party in writing of the
commencement thereof; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have
under this Section 5 except to the extent 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 that it may have to an indemnified party otherwise than under this Section 5. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with
any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 5 for any legal or other expenses,
other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. Notwithstanding the election of the indemnifying party to assume
the defense of such action, such indemnified party shall have the right to employ separate counsel and to participate in the defense of such action, and the indemnified party shall bear the fees,
costs and expenses of such separate counsel (and shall pay such fees, costs and expenses promptly after receipt of any invoice therefor from the indemnifying party). However, if any of the following
circumstances shall occur, the indemnifying party shall bear the fees, costs and expenses of such separate counsel (and shall pay such fees, costs and expenses promptly after receipt of any invoice
therefor from the indemnified party): (i) in the reasonable judgment of the indemnified party, the use of counsel chosen by the indemnifying party to represent such indemnified party would
present such counsel with a conflict of interest; (ii) the defendants in, or targets of, any such action include both an indemnified party and the indemnifying party, and such indemnified party
shall have reasonable concluded that there may be legal defenses available to it or to other indemnified parties which are different from or in addition to those available to the indemnifying party
(in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party); (iii) the indemnifying party shall not have employed
counsel satisfactory to such indemnified party, in the exercise of such indemnified party's reasonable judgment, to represent such indemnified party within a reasonable time after notice of the
institution of any such action; or (iv) the indemnifying party shall authorize such indemnified party to employ separate counsel at the expense of the indemnifying party. 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 action in respect of which any
indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such
indemnified party from all liability on any claims that are 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 any indemnified party. 

        (d)   If
the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or
(b) above, then each indemnifying party shall, to the extent such indemnification is unavailable or insufficient, contribute to the amount paid or payable by such indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above in such proportion as is appropriate to reflect the relative
fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a 

11

 

material
fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case
may be, on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the
Holders of the Notes shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Notes pursuant to a Registration
Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company. 

        (e)   The
agreements contained in this Section 5 shall survive the sale of the Notes pursuant to a Registration Statement and shall remain in full force and effect,
regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 

        6.    Additional Interest Under Certain Circumstances.    

        (a)   By
way of liquidated damages, additional interest (the "Additional Interest") with respect to the Initial Notes shall be
assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a "Registration
Default"): 

        (i)    any
Registration Statement required by this Agreement is not filed with the Commission on or prior to the Filing Deadline or Shelf Filing Deadline, as applicable; 

        (ii)   any
Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline; 

        (iii)  the
Registered Exchange Offer has not been consummated on or prior to the Consummation Deadline; or 

        (iv)  any
Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be
effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Notes during the periods specified herein because
either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any 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, or (2) it shall be necessary to amend such Registration
Statement or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder. 

Each
of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to
operation of law or as a result of any action or inaction by the Commission. 

        Additional
Interest shall accrue on the Initial Notes over and above the interest set forth in the title of the Initial Notes from and including the date on which any such Registration
Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of $.05 per week per $1,000 principal amount of Initial Notes (the
"Additional Interest Rate") for the first 90-day period immediately following the occurrence of such Registration Default. The Additional
Interest Rate shall increase by an additional $.05 per week per $1,000 principal amount of Initial Notes with respect to each subsequent 90-day period until all Registration Defaults have
been cured, up to a maximum Additional 

12

 

Interest
Rate of $.50 per week per $1,000 principal amount of Notes. Additional Interest shall not accrue under more than one of clauses (i) through (iv) of the preceding paragraph at
any one Time. 

        (b)   A
Registration Default referred to in Section 6(a)(iv) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration
Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf
Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared
effective to permit Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in such Shelf Registration Statement or the
related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related
prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 

        (c)   Any
amounts of Additional Interest due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the Notes. 

        (d)   "Transfer Restricted Notes" means each Note until (i) the date on which such Note has been exchanged by a person
other than a broker-dealer for a freely transferable Exchange Note in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an
Initial Note for an Exchange Note, the date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus
contained in the Exchange Offer Registration Statement, (iii) the date on which such Note has been effectively registered under the Securities Act and disposed of in accordance with the Shelf
Registration Statement or (iv) the date on which such Note 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. 

        7.    Rules 144 and 144A.    The Company shall use its 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 request of any Holder of Notes, make
publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any
Holder of Notes may reasonably request, all to the extent required from time to time to enable such Holder to sell Notes without registration under the Securities Act within the limitation of the
exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Initial Notes
identified to the Company by the Initial Purchasers upon request. Upon the request of any Holder of Initial Notes, the Company shall deliver to such Holder a written statement as to whether it has
complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 

        8.    Underwritten Registrations.    If any of the Transfer Restricted Notes covered by any Shelf Registration are to
be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering ("Managing
Underwriters") will be selected, with the reasonable approval of the Company, by the Holders of a majority in aggregate principal amount of such Transfer Restricted Notes to be
included in such offering. 

        No
person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person's Transfer Restricted Notes 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. 

13

 

        9.    Miscellaneous.    

        (a)    Remedies.    Each of the parties hereto acknowledges and agrees that the payment of Additional Interest as
provided in Section 6 hereof shall be the exclusive remedy for any failure by the Company to comply with its obligations under Sections 1 and 2 hereof. 

        (b)    No Inconsistent Agreements.    The Company will not on or after the date of this Agreement enter into any
agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof. 

        (c)    Amendments and Waivers.    The provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Notes affected by
such amendment, modification, supplement, waiver or consent. Without the consent of the Holder of each Note, however, no modification may change the provisions relating to the payment of Additional
Interest. 

        (d)    Notices.    All notices and other communications provided for or permitted hereunder shall be made in writing
by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery:

ANNEX A  

        Each
broker-dealer that receives Exchange Notes 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 Notes. 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 Notes received in exchange
for Initial Notes where such Initial Notes 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." 

ANNEX B  

        Each
broker-dealer that receives Exchange Notes for its own account in exchange for Initial Notes, where such Initial Notes 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 Notes. See "Plan of Distribution." 

ANNEX C  

PLAN OF DISTRIBUTION  

        Each
broker-dealer that receives Exchange Notes 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 Notes. 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 Notes received in exchange for
Initial Notes where such Initial Notes 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                        , 2003, all
dealers effecting transactions in the Exchange Notes may be required to deliver a prospectus.(1) 

	(1)
	In
addition, if applicable the legend required by Item 502(b) of Regulation S-K will appear on the outside back cover page of the Exchange Offer prospectus. 

        The
Company will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes 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 Notes
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 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
Notes. Any broker-dealer that resells Exchange Notes 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 Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of Exchange Notes 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 Notes) other than commissions
or concessions of any brokers or dealers and will indemnify the Holders of the Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.
