Credit Suisse First Boston Corporation
Salomon Smith Barney Inc.
RBC Dominion Securities Corporation
Simmons & Company International
c/o Credit Suisse First Boston Corporation
Eleven Madison Avenue
New York, New York 10010-3629

Dear Sirs:

     Varco International, Inc., a Delaware corporation (the "Issuer"), proposes
to issue and sell to Credit Suisse First Boston Corporation, Salomon Smith
Barney Inc., RBC Dominion Securities Corporation and Simmons & Company
International (collectively, the "Initial Purchasers"), upon the terms set forth
in a purchase agreement of even date herewith (the "Purchase Agreement"),
$200,000,000 aggregate principal amount of its 7 1/4% Senior Notes due 2011 (the
"Initial Securities") to be guaranteed (the "Guaranties") by Varco I/P, Inc.;
Tubo-FGS, LLC; Tuboscope (Holding U.S.) Inc.; Fiber Glass Systems Holdings, LLC;
Fiber Glass Systems, LP; Varco, LP; Quality Tubing Inc.; Tuboscope Pipeline
Services Inc.; and Environmental Procedures Inc. (the "Guarantors" and together
with the Issuer, the "Company"). The Initial Securities will be issued pursuant
to an Indenture, dated as of May 1, 2001, (the "Indenture") among the Issuer,
the Guarantors and Bank of New York Trust Company of Florida (the "Trustee"). As
an inducement to the Initial Purchasers, the Company agrees with the Initial
Purchasers, for the benefit of the holders of the Initial Securities (including,
without limitation, the Initial Purchasers) and the Exchange Securities (as
defined below) (collectively the "Holders"), as follows:

     1.   Registered Exchange Offer. Unless the Registered Exchange Offer (as
defined below) is not permitted by applicable law, the Company shall, at its own
cost, prepare and, not later than 120 days after (or if the 120th day is not a
business day, the first business day thereafter) the date of original issue of
the Initial Securities (the "Issue 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
<PAGE>

1933, as amended (the "Securities Act"), with respect to a proposed offer (the
"Registered Exchange Offer") to the Holders of Transfer Restricted Securities
(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 Securities, a like
aggregate principal amount of debt securities (the "Exchange Securities") of the
Company issued under the Indenture and identical in all material respects to the
Initial Securities (except for the transfer restrictions relating to the Initial
Securities and the provisions relating to the matters described in Section 6
hereof) that would be registered under the Securities Act. The Company shall use
its best efforts to cause such Exchange Offer Registration Statement to become
effective under the Securities Act within 180 days (or if the 180th day is not a
business day, the first business day thereafter) after the Issue Date of the
Initial Securities and shall keep the Exchange Offer Registration Statement
effective 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"). The Initial
Securities and the Exchange Securities are herein collectively referred to as
the "Securities."

     If the Company effects the Registered Exchange Offer, the Company will be
entitled to close the Registered Exchange Offer 30 days after the commencement
thereof provided that the Company has accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer.

     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 Securities (as defined in Section 6
hereof) electing to exchange the Initial Securities for Exchange Securities
(assuming that such Holder is not an affiliate of the Company within the meaning
of the Securities Act, acquires the Exchange Securities in the ordinary course
of such Holder's business and has no arrangements with any person to participate
in the distribution of the Exchange Securities and is not prohibited by any law
or policy of the Commission from participating in the Registered Exchange Offer)
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 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 Securities (as defined below), 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, among other things, the information set forth in (a)
Annex A hereto on the cover, (b) Annex B hereto in the "Exchange Offer
Procedures" section (or similarly titled section) and the "Purpose of the
Exchange Offer" section (or similarly titled section), and (c) 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 Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Exchange Securities acquired in exchange for Securities constituting any portion
of an unsold allotment is required to deliver a prospectus

                                       2
<PAGE>

containing the information required by Items 507 or 508 of Regulation S-K under
the Securities Act, as applicable, in connection with such sale.

     The Company shall use its 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 Securities; 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 Securities 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 Securities
for a period of not less than 90 days after the consummation of the Registered
Exchange Offer.

     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 and related documents;

     (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
with an address in the Borough of Manhattan, The City of New York, which may be
the Trustee or an affiliate of the Trustee;

     (d)  permit Holders to withdraw tendered Securities 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.

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

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

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

     (z)  cause the Trustee to authenticate and deliver promptly to each Holder
of the Initial Securities, Exchange Securities equal in principal amount to the
Initial Securities of such Holder so accepted for exchange.

                                       3
<PAGE>

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities shall be considered collectively to be a single class for all
purposes of the Indenture, including, without limitations waivers, amendments,
redemptions and offers to purchase.

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

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered 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 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
Securities and (v) if such Holder is a broker-dealer, that it will receive
Exchange Securities for its own account in exchange for Initial Securities 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 Securities.

     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.

     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 within
180 days of the Issue Date, (iii) any Initial Purchaser so requests with respect
to the Initial Securities not eligible to be exchanged for Exchange Securities
in the Registered Exchange Offer and held by it following consummation of the
Registered Exchange Offer or (iv) any 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

                                       4
<PAGE>

Registered Exchange Offer, such Holder does not receive freely tradeable
Exchange Securities on the date of the exchange, the Company shall take the
following actions:

     (a)  The Company shall, at its cost, as promptly as practicable (but in no
event later than the later of (i) 120 days after (or if the 120th day is not a
business day, the first business day thereafter) the Issue Date and (ii) 60 days
after so otherwise required or requested pursuant to this Section 2) file with
the Commission and thereafter shall use its best efforts to cause to be declared
effective one 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 Securities (as defined in Section 6
hereof) 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
Securities 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 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 Securities,
until the earlier to occur of (i) the time when the Securities covered by the
Shelf Registration Statement can be sold pursuant to Rule 144 without any
limitations under clauses (c), (e), (f) and (h) of Rule 144 and (ii) two years
(or for such longer period if extended pursuant to Section 3(j) below) from the
Issue Date or such shorter period that will terminate when all the Securities
covered by the Shelf Registration Statement (a) have been sold pursuant thereto
or (b) are no longer restricted securities (as defined in Rule 144 under the
Securities Act, or any successor rule thereof). The Company shall be deemed not
to have used its best efforts to keep the Shelf Registration Statement effective
during the requisite period if it voluntarily takes any action that would result
in Holders of Securities covered thereby not being able to offer and sell such
Securities during that period, unless such action is required by applicable law.

     (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:

                                       5
<PAGE>

     (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 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 (or similarly titled section)
and the "Purpose of the Exchange Offer" section (or similarly titled 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 Items 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," reasonably acceptable to the Initial Purchasers, which shall

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
Securities 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 Securities
pursuant to the Shelf Registration Statement, as selling securityholders.

     (b)  The Company shall give written notice to the Initial Purchasers, the
Holders of the Securities 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;

                                       6
<PAGE>

          (iv)  of the receipt by the Company or its legal counsel of any
     notification with respect to the suspension of the qualification of the
     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 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 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 Securities 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 Securities 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 Securities in connection with the offering and sale of the Securities
covered by the prospectus, or any amendment or supplement thereto, included in
the Shelf Registration Statement.

     (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 Securities covered by the
prospectus, or any amendment or supplement thereto, included in such Exchange
Offer Registration Statement.

                                       7
<PAGE>

     (h)  Prior to any public offering of the Securities, pursuant to any
Registration Statement, the Company shall register or qualify or cooperate with
the Holders of the Securities included therein and their respective counsel in
connection with the registration or qualification of the Securities for offer
and sale under the securities or "blue sky" laws of such states of the United
States as any Holder of the Securities 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 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 Securities to
facilitate the timely preparation and delivery of certificates representing the
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 may request a reasonable period of time prior to sales of the
Securities pursuant to such Registration Statement.

     (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 Securities or
purchasers of Securities, 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 Securities 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 Securities 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 Securities 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 Securities
and the Exchange Securities and provide the applicable trustee with printed
certificates for the Initial Securities and the Exchange Securities 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

                                       8
<PAGE>

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.

     (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 Securities to be sold pursuant
to the Shelf Registration Statement to furnish to the Company such information
regarding the Holder and the distribution of the Securities as the Company may
from time to time reasonably require for inclusion in the Shelf Registration
Statement, and the Company may exclude from such registration the Securities of
any Holder that unreasonably 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 Securities shall reasonably request in
order to facilitate the disposition of the Securities 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 Securities, 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 Securities 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 Securities 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; provided further, that any person to whom information is provided under
this Section 3(p) agrees in writing to maintain the confidentiality of such
information to the extent such information is not in the public domain.

     (q)  In the case of any Shelf Registration, the Company, if requested by
any Holder of Securities covered thereby, shall cause (i) its counsel to deliver
an opinion and updates thereof relating to the Securities 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 covering the matters customarily covered in opinions
requested in underwritten offerings in the form acceptable to the managing
underwriters (ii) its officers to

                                       9
<PAGE>

execute and deliver all customary documents and certificates and updates thereof
requested by any underwriters of the applicable Securities and (iii) its
independent public accountants to provide to the selling Holders of the
applicable Securities 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.

     (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 Section 6(c) of the
Purchase Agreement with such changes as are customary in connection with the
preparation of a Registration Statement and (ii) its independent public
accountants 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 6(a) and 6(f) of the Purchase
Agreement, with appropriate date changes.

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

     (t)  The Company will use its best efforts to (a) if the Initial Securities
have been rated prior to the initial sale of such Initial Securities, confirm
such ratings will apply to the Securities covered by a Registration Statement,
or (b) if the Initial Securities were not previously rated, cause the Securities
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 Securities 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 Securities 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 Securities 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 Securities, 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 Securities, (ii) indemnifying any such qualified independent underwriter
to the extent of the indemnification of underwriters provided

                                      10
<PAGE>

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 best efforts to take all other steps
necessary to effect the registration of the Securities covered by a Registration
Statement contemplated hereby.

     4.   Registration Expenses. The Company shall bear all fees and expenses
incurred in connection with the performance of its obligations under Sections 1
through 3 hereof (including the reasonable fees and expenses, if any, of Simpson
Thacher & Bartlett, counsel for the Initial Purchasers, incurred in connection
with the Registered Exchange Offer), whether or not the Registered Exchange
Offer or a Shelf Registration is filed or becomes effective, and, in the event
of a Shelf Registration, shall bear or reimburse the Holders of the Securities
covered thereby for the reasonable fees and disbursements of one firm of counsel
designated by the Holders of a majority in principal amount of the Initial
Securities covered thereby to act as counsel for the Holders of the Initial
Securities in connection therewith.

     5.   Indemnification. (a) The Company agrees to indemnify and hold harmless
each Holder of the Securities, 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 Securities) 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 Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered by such Holder or
Participating Broker-Dealer under the Securities Act in connection with such
purchase and any

                                      11
<PAGE>

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 Securities 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 Securities if requested by such Holders.

     (b)  Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and its officers and 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
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, shall reimburse, as incurred, the Company for any legal
or other expenses reasonably incurred by the Company or any such 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 of its controlling persons.

     (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 of the commencement thereof; but the omission so to notify
the indemnifying party will not, in any event, relieve the indemnifying party
from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. 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 (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying 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

                                      12
<PAGE>

indemnified party in connection with the defense thereof. No indemnifying party
shall, without the prior written consent of the indemnified party, 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 includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action.

     (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 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 (i) in such proportion as is appropriate to reflect the relative benefits
received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the exchange of the Securities, pursuant to
the Registered Exchange Offer, or (ii) if the allocation provided by the
foregoing clause (i) 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 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 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 Securities 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 Securities 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 Securities 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.

                                      13

     6.    Additional Interest Under Certain Circumstances. (a) Additional
interest (the "Additional Interest") with respect to the Initial Securities
shall be assessed as follows if any of the following events occur (each such
event in clauses (i) through (iii) below a "Registration Default":

     (i)   If by August 29, 2001, neither the Exchange Offer Registration
Statement nor a Shelf Registration Statement has been filed with the Commission;

     (ii)  If by October 29, 2001, neither the Registered Exchange Offer is
consummated nor, if required in lieu thereof, the Shelf Registration Statement
is declared effective by the Commission; or

     (iii) If after either the Exchange Offer Registration Statement or the
Shelf Registration Statement is declared effective (A) such Registration
Statement thereafter ceases to be effective; or (B) such Registration Statement
or the related prospectus ceases to be usable (except as permitted in paragraph
(b)) in connection with resales of Transfer Restricted Securities 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.

Additional Interest shall accrue on the Initial Securities over and above the
interest set forth in the title of the Securities 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 (such period shall be
referred to herein as the "Registration Default Period"), at a rate of 0.25% per
annum for the first 90 days of the Registration Default period and at a rate of
0.50% per annum thereafter for the remaining period of the Registration Default
Period.

     (b)   A Registration Default referred to in Section 6(a)(iii)(B) 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 clause (i), (ii)
or (iii) of Section 6(a) above will be payable in cash on the regular interest
payment dates with respect to the Initial

                                       14
<PAGE>

Securities. The amount of Additional Interest will be determined by multiplying
the applicable Additional Interest rate by the principal amount of the Initial
Securities, multiplied by a fraction, the numerator of which is the number of
days such Additional Interest rate was applicable during such period (determined
on the basis of a 360-day year comprised of twelve 30-day months), and the
denominator of which is 360.

     (d)  "Transfer Restricted Securities" means each Security until (i) the
date on which such Transfer Restricted Security has been exchanged by a person
other than a broker-dealer for a freely transferable Exchange Security in the
Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the
Registered Exchange Offer of an Initial Security 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 Initial Security 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 Initial Security is distributed to the public pursuant to
Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) or
another substantially similar resale exemption promulgated in the future 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 Initial Securities, 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 Initial Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Initial Securities 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 Securities identified to the
Company by the Initial Purchasers upon request. Upon the request of any Holder
of Initial Securities, 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
Securities 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 by
the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering and shall be reasonably
acceptable to the Company. The Company shall pay the fees and expenses of such
investment bankers and managers only to the extent specifically provided in
Section 4. In no event shall the Company be responsible for paying any
underwriting discounts or commissions in connection with such underwritten
offering.

     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

                                       15
<PAGE>

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.

     9.   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, except by the Company and the written
consent of the Holders of a majority in principal amount of the Securities
affected by such amendment, modification, supplement, waiver or consents.
Notwithstanding the foregoing, a waiver or consent to departure from the
provisions hereof that relates exclusively to the rights of Holders whose
securities are being tendered pursuant to the Exchange Offer and that does not
affect directly or indirectly the rights of other Holders whose securities are
not being tendered pursuant to such Exchange Offer may be given by the Holders
of a majority of the outstanding principal amount of Transfer Restricted
Securities being tendered or registered.

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

     (c)  No Inconsistent Agreements. The Company has not, as of the date
hereof, entered into, nor shall it, on or after the date hereof, enter into, any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders herein or otherwise conflicts with the provisions hereof.

     (d)  Successors and Assigns. This Agreement shall be binding upon (i) the
successors and assigns of each of the parties to this Agreement, without the
need for an express assignment, and (ii) subsequent Holders of the Securities.

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

     (h)  Severability. If any one or more of the provisions contained herein,
or the application thereof in any circumstance, is held invalid, illegal or
unenforceable, the validity, legality and enforceability of any such provision

     (i)  Securities Held by the Company. Whenever the consent or approval of
Holders of a specified percentage of principal amount of Securities is required
hereunder, Securities held by the Company or its affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

     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
Initial Securities where such Initial 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 Initial 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 Initial Securities where such Initial 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. 1

     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 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 brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
