Dear Sirs:
 
     Coltec Industries Inc, a Pennsylvania corporation (the "Issuer"), proposes
to issue and sell to Credit Suisse First Boston Corporation, BT Alex. Brown
Incorporated, BancAmerica Robertson Stephens Inc. and NationsBanc Montgomery
Securities LLC (collectively, the "Initial Purchasers"), upon the terms set
forth in a purchase agreement of even date herewith (the "Purchase Agreement"),
$300,000,000 aggregate principal amount of its 7 1/2% Senior Notes Due 2008 (the
"Initial Securities") to be unconditionally guaranteed (the "Guaranties") by the
parties listed on the signature page hereto (the "Guarantors" and together with
the Issuer, the "Company"). The Initial Securities will be issued pursuant to an
Indenture, dated as of April 16, 1998 (the "Indenture") among the Issuer, the
Guarantors named therein and Bankers Trust Company (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), the Exchange Securities (as defined
below) and the Private Exchange Securities (as defined below) (collectively the
"Holders"), as follows:
 
     1. Registered Exchange Offer.  The Company shall, at its own cost, prepare
and, within 90 days after (or if the 90th 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 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 reasonable best efforts to cause such Exchange Offer Registration Statement
to become effective under the Securities Act within 150 days (or if the 150th
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 20 business 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").
 
     If the Company effects the Registered Exchange Offer, the Company will be
entitled to close the Registered Exchange Offer 20 business 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.
   2
 
     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 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, acquired for its own account as a result of
market making activities or other trading activities, for Exchange Securities
(an "Exchanging Dealer"), is required to deliver a prospectus containing
substantially the information set forth in (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 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 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 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 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.
 
     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities 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 Securities 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 (including the
existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States, but excluding
provisions relating to the matters described in Section 6 hereof) to the Initial
Securities (the "Private Exchange Securities"). The Initial Securities, the
Exchange Securities and the Private Exchange Securities are herein collectively
called the "Securities".
 
     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) except as provided elsewhere herein, keep the Registered Exchange
     Offer open for not less than 20 business 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;
 
                                        2
   3
 
          (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 or
the Private Exchange, 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 and the Private
     Exchange;
 
          (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 or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.
 
     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 will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.
 
     Interest on each Exchange Security and Private Exchange Security 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 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 or the Exchange 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 (or the Private Exchange 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 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
 
                                        3
   4
 
Dealer) that participates in the 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 more than 60 days after so required or requested pursuant to this
     Section 2) file with the Commission and thereafter shall use its reasonable
     best efforts to cause to be declared effective 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 Securities 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 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 Securities, for a period of two years (or for such longer period
     if extended pursuant to this paragraph (b) or to Section 3(j) below) from
     the date of its effectiveness or such shorter period that will terminate
     when all the Securities covered by the Shelf Registration Statement (i)
     have been sold pursuant thereto or (ii) are no longer restricted securities
     (as defined in Rule 144 under the Securities Act, or any successor rule
     thereof); provided, however, the Company shall not be obligated to keep the
     Shelf Registration Statement continuously effective to the extent set forth
     above if (i) the Company determines, in its reasonable judgment, upon
     advice of counsel, as authorized by a resolution of its Board of Directors,
     that the continued effectiveness and usability of the Shelf Registration
     Statement would (x) require the disclosure of material information, which
     the Company has a bona fide business reason for preserving as confidential,
     or (y) interfere with any financing, acquisition, corporate reorganization
     or other material transaction or development involving the Company or any
     of its subsidiaries or its parent or the contemplated timing thereof,
     provided that the failure to keep the Shelf Registration Statement
     effective and usable for offers and sales of Securities for such reason
     shall last no longer than 45 days in any three-month period or three
     periods not to exceed an aggregate of 90 days in any 12-month period
     (whereafter Additional Interest (as defined in Section 6(a)) shall accrue
     and be payable), and (ii) the Company promptly thereafter complies with the
     requirements of Section 3(j) hereof, if applicable; provided further that
     the number of days of any actual Suspension Period (as defined below) shall
     be added on to the end of the two-year period specified above. Any such
     period during which the Company is excused from keeping the Shelf
     Registration Statement effective and usable for offers and sales of
     Securities is referred to herein as a "Suspension Period." A Suspension
     Period shall commence on and include the date that the Company gives notice
     that the Shelf Registration Statement is no longer effective or the
     prospectus included therein is no longer usable for offers and sales of
     Securities and shall end on the earlier to occur of (1) the date on which
     each seller of Securities covered by the Shelf Registration Statement
     either receives the copies of the supplemented or amended prospectus
     contemplated by Section 3(j) hereof or is advised in writing by the Company
     that the use of the prospectus may be resumed and (2) the expiration of 45
     days in any three-month period or three periods not to exceed an aggregate
     of 90 days in any 12-month period during which one or more Suspension
     Periods has been in effect. Except as provided above, 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.
 
                                        4

     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 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
     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 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
     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 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.
 
          After the effectiveness of the Registration Statement, the Company
     shall give written notice to the Initial Purchasers, the Holders and any
     such Participating Broker-Dealer (which notice pursuant to clauses (i)-(iv)
     hereof shall be accompanied by an instruction to suspend the use of the
     prospectus until the requisite changes have been made):
 
             (i) of any request by the Commission for amendments or supplements
        to the Registration Statement or the prospectus included therein or for
        additional information;
 
             (ii) 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;
 
             (iii) 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
 
             (iv) of the happening of any event (including, without limitation,
        of any event resulting in a Suspension Period) 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.
 
                                        5
   6
 
          (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 Exchanging Dealer and 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.
 
          (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 reasonably
     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 (other than an event resulting in
     a Suspension Period) contemplated by paragraphs (i) through (iv) 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 (i) through
     (iv) of Section 3(b) above to suspend the use of the prospectus until the
     requisite changes to the prospectus have
 
                                        6
   7
 
     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 (without duplication of any extension under Section 2(b))
     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, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.
 
          (l) The Company 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 of the Company
     satisfying the provisions of Section 11(a) of the Securities Act, no later
     than 45 days after the end of four quarterly periods (or 90 days, if such
     period is a fiscal year) beginning with the Company's first fiscal quarter
     commencing after the effective date of the Registration Statement, which
     statement shall cover such four quarterly periods.
 
          (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. Each Holder of Securities or any underwriter, attorney,
     accountant or agent conducting an inspection under this Section 3(p) will
     be required, as a condition to conducting such investigation, to agree that
     information obtained by it as a result of such inspections shall be deemed
     confidential and shall not be used by it as the basis for any market
     transactions in the securities of the Company unless and until such
     information is generally available to the public.
 
                                        7
   8
 
          (q) In the case of any Shelf Registration, the Company, if requested
     by any Holder of Securities covered thereby, shall cause (i) its counsel
     (which may include internal counsel) to deliver an opinion and updates
     thereof relating to the Securities in customary form and substance
     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; (ii) its officers to 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 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 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 public 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 substantially 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 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 6(a) and (f) of the Purchase Agreement, with appropriate
     date changes.
 
          (s) If a Registered Exchange Offer or a Private Exchange 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 or the Private Exchange Securities, as the case
     may be, 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 or the Private Exchange Securities, as
     the case may be; in no event shall the Initial Securities be marked as paid
     or otherwise satisfied.
 
          (t) The Company will use its reasonable 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, in each case,
     if so requested prior to the effectiveness of the Registration Statement 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
     reasonably 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
     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 Securities covered
     by a Registration Statement contemplated hereby. The Initial Purchasers
     agree to provide any reasonable assistance requested by the Company in
     complying with its
 
                                        8
   9
 
     obligations pursuant to this Section 3, including, without limitation,
     identifying and contacting Holders entitled to participate in the
     Registered Exchange Offer.
 
     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; provided that such Holders shall be
responsible for any and all underwriting discounts and commissions and all other
costs and expenses customarily borne by securityholders in similar
circumstances; provided further that prior to employing counsel in connection
with a Registered Exchange Offer, the Initial Purchasers will consult with the
Company and the Company's counsel to determine if separate counsel is necessary.
 
     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, such controlling persons and their respective
affiliates, directors, officers, employees, representatives and agents 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,
subject to the limitation set forth in the immediately preceding clause, 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 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, its subsidiaries, affiliates,
directors, officers, employees, representatives and agents and any such
controlling person and each person, if any, who controls the Company within the
meaning of the Securities Act or the
 
                                        9
   10
 
Exchange Act from and against any losses, claims, damages or liabilities or any
actions in respect thereof, to which the Company, its subsidiaries, affiliates,
directors, officers, employees, representatives and agents and any such
controlling person 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
them 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
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
                                       10
   11
 
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.
 
     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 within 90 days of April 16, 1998, neither the Exchange Offer
     Registration Statement nor a Shelf Registration Statement has been filed
     with the Commission;
 
          (ii) If within 180 days of April 16, 1998, 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.
 
Subject to paragraph (b) below, 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, at a rate of 0.50% per annum, calculated on the principal amount of the
Notes as of the day on which such interest is payable.
 
     (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, (y) other material events, with respect
to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus or (z) a Suspension Period not to exceed 45
days in any three-month period or three periods not to exceed an aggregate of 90
days in any 12-month period pursuant to Section 2(b) 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 or until the Company is
no longer required to keep such Registration Statement effective or such
prospectus useable pursuant to the terms of this Agreement.
 
     (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 Securities. The amount of Additional
Interest will be determined by multiplying the applicable Additional Interest
rate by the principal
                                       11
   12
 
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
brokerdealer 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 Security is distributed to the public pursuant to Rule 144
under the Securities Act or is saleable pursuant to Rule 144(k) under the
Securities Act.
 
     7. Rules 144 and 144A.  The Company shall use its reasonable best efforts
to file the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time the Company is not required
to file such reports, it will, upon the 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 reasonable 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.
 
     No person may participate in any underwritten registration hereunder unless
such person (i) agrees to sell such person's Transfer Restricted Securities on
the basis reasonably provided in any underwriting arrangements approved by the
persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.
 
     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.
